3 Minor hashing refactoring.
4 * fns.c (SXHASH_REDUCE): Move to lisp.h.
5 (sxhash_float): Return EMACS_UINT, for consistency with the other
7 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
8 non-static inline function and therefore can't use static vars.
9 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
10 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
11 with the other hash functions.
13 2013-02-09 Eli Zaretskii <eliz@gnu.org>
15 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
16 XXXXXX part of the temporary file pattern is not downcased even
17 when w32-downcase-file-names is non-nil. (Bug#13661)
19 * xdisp.c (decode_mode_spec): Remove handling of %t.
21 * msdos.c (careadlinkatcwd): Remove.
23 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>

27 (load_each_byte): Remove. Update users.
29 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
31 * search.c (scan_buffer): Calculate end byte position just once.
32 (scan_newline): Do not recalculate start_byte.
33 (search_command): Use eassert.
34 * syntax.c (struct lisp_parse_state): New member location_byte.
35 (scan_sexps_forward): Record from_byte and avoid redundant
36 character to byte position calculation ...
37 (Fparse_partial_sexp): ... here. Break too long line.
39 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
41 * lisp.h (make_uninit_vector): New function.
42 * alloc.c (Fvector, Fmake_byte_code):
43 * ccl.c (Fregister_ccl_program):
44 * charset.c (Fdefine_charset_internal, define_charset_internal):
45 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
46 * composite.c (syms_of_composite):

49 * ftfont.c (ftfont_shape_by_flt):
50 * indent.c (recompute_width_table):
51 * nsselect.m (clean_local_selection_data):
52 * syntax.c (init_syntax_once):
53 * w32unsubscribe.c (uniscribe_shape):
54 * window.c (Fcurrent_window_configuration):
55 * xfaces.c (Fx_family_fonts):

58 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
60 * coding.c (Fdefine_coding_system_internal): Use AREF where
61 argument is known to be a vector.
62 * fns.c (Flocale_info): Likewise for ASET.
63 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
64 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
66 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
68 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
71 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
72 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
73 updateCollectionBehaviour.
75 * nsterm.m (NEW_STYLE_FS): Remove.
76 (ns_last_use_native_fullscreen): New variable.
77 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.

79 if isFullscreen returns YES.
80 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
81 (check_native_fs): New function.
82 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
83 (ns_term_init): Remove NEW_STYLE_FS.

87 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
89 (window:willUseFullScreenPresentationOptions:): New method.
90 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
91 Hide toolbar if not enabled (Bug#13444).

94 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
95 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
96 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
97 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
98 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
99 (syms_of_nsterm): Add ns-use-native-fullscreen.
101 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
103 * fileio.c (Qchoose_write_coding_system): Now static.
105 2013-02-04 Eli Zaretskii <eliz@gnu.org>
107 * xdisp.c (window_buffer_changed): region_showing can be negative,
108 which still means region is being displayed.
109 (redisplay_internal): Resurrect code that forced redisplay of the
110 whole window when showing region and the mark has changed. Record
111 the new mark position to allow redisplay optimizations.
112 (display_line): If it->region_beg_charpos is non-zero, set the
113 window's region_showing member to -1. (Bug#13623) (Bug#13626)
115 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
116 not bitfield of 1 bit.
118 2013-02-03 Daniel Colascione <dancol@dancol.org>
120 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
121 daemon mode works on cygw32 when Emacs is installed and not just
124 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
126 Avoid file time stamp bug on MS-Windows (Bug#13149).
127 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
128 as FAT32 doesn't update time stamps when truncating them.
129 Also, check that a file time stamp is not a multiple of 100 ns;
130 this should catch all instances of the problem on MS-Windows,
131 as its native file system resolution is 100 ns or worse, and
132 checking for a non-multiple of 100 ns should impose only a small
133 overhead on systems with ns resolution.
135 2013-02-02 Eli Zaretskii <eliz@gnu.org>
137 Avoid encoding file names on MS-Windows when they need to be run
138 through dostounix_filename.
139 * w32.c (normalize_filename): Accept an additional argument
140 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
141 downcase it even if w32-downcase-file-names is non-nil.
142 (dostounix_filename): Accept an additional argument MULTIBYTE and
143 pass it to normalize_filename.
144 (emacs_root_dir): Adjust.
146 * msdos.h (dostounix_filename): Adjust prototype.
148 * w32.h (dostounix_filename): Adjust prototype.
150 * msdos.c (dostounix_filename): Accept an additional argument and
152 (init_environment): Adjust callers of dostounix_filename.
154 * fileio.c (Ffile_name_directory, file_name_as_directory)
155 (directory_file_name, Fexpand_file_name)
156 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
158 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
160 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
161 variables, as egetenv is case-insensitive for DOS_NT.
163 * dired.c (file_name_completion): Don't call Fdirectory_file_name
164 with an encoded file name.
166 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
167 calls to dostounix_filename.
169 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
171 * unexw32.c (unexec): Adjust call to dostounix_filename.
173 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
175 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
178 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
181 * callproc.c (Fcall_process): Make sure program name in PATH and
182 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
183 is passed to exec/spawnve, which fails unless the file-name
186 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
187 even if w32-quote-process-args is nil.
189 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
191 Fix timestamp bug when write-region appends nothing (Bug#13149).
192 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
193 the file's time stamp doesn't change if Emacs happens to write nothing
194 to the file, and on a buggy file system this could cause Emacs to
195 incorrectly infer that the file system doesn't have the bug.
196 Avoid this problem by inhibiting the inference in this case.
198 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
200 * window.h (struct window): Convert base_line_number, base_line_pos
201 and column_number_displayed members from Lisp_Object to ptrdiff_t.
202 Convert region_showing member from Lisp_Object to bitfield.
203 Remove sequence_number member. Adjust comments.
204 * window.c (sequence_number): Remove.
205 (make_window): Initialize column_number_displayed.
206 * print.c (print_object): Follow the printed representation of
207 frames and print window pointer to distinguish between windows.
208 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
209 * xdisp.c (wset_base_line_number, wset_base_line_pos)
210 (wset_column_number_displayed, wset_region_showing): Remove.
211 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
212 (try_scrolling, try_cursor_movement, redisplay_window)
213 (try_window_reusing_current_matrix, try_window_id, display_line)
214 (display_mode_lines, decode_mode_spec): Adjust users.
215 * .gdbinit (pwinx): Do not print sequence_number.
217 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
219 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
220 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
221 * dired.c: Include <fcntl.h>.
222 (open_directory): New function, which uses open and fdopendir
223 rather than opendir. DOS_NT platforms still use opendir, though.
224 (directory_files_internal, file_name_completion): Use it.
225 (file_attributes): New function, with most of the old Ffile_attributes.
226 (directory_files_internal, Ffile_attributes): Use it.
227 (file_attributes, file_name_completion_stat): First arg is now fd,
228 not dir name. All uses changed. Use fstatat rather than lstat +
230 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
231 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
232 (emacs_readlinkat): New function, with much of the old
233 Ffile_symlink_p, but with an fd argument for speed.
234 It uses readlinkat rather than careadlinkatcwd, so that it
235 need not assume the working directory.
236 (Ffile_symlink_p): Use it.
237 * filelock.c (current_lock_owner): Use emacs_readlinkat
238 rather than emacs_readlink.
239 * lisp.h (emacs_readlinkat): New decl.
240 (READLINK_BUFSIZE, emacs_readlink): Remove.
241 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
242 (emacs_norealloc_allocator, emacs_readlink): Remove.
243 This stuff is moved to fileio.c.
244 * w32.c (fstatat, readlinkat): New functions.
245 (careadlinkat): Don't check that fd == AT_FDCWD.
246 (careadlinkatcwd): Remove; no longer needed.
248 2013-01-31 Glenn Morris <rgm@gnu.org>
250 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
251 (Fwrite_region): Update for new choose_write_coding_system args.
252 Move the last piece of choose_write_coding_system here. (Bug#13522)
253 (syms_of_fileio): Add choose-write-coding-system.
255 2013-01-30 Eli Zaretskii <eliz@gnu.org>
257 * w32.c (sys_open): Zero out the flags for the new file descriptor.
258 (sys_close): Zero out the flags for the file descriptor before
259 closing it. (Bug#13546)
261 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
262 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
263 CharNextExA and CharPrevExA to iterate over file names encoded in
266 * w32.c (w32_get_long_filename, init_environment, readlink):
267 Support file names encoded in DBCS codepages.
268 (readlink): Use the current file-name-coding-system, not the ANSI
269 codepage, to decode and handle targets of symlinks.
271 2013-01-28 Eli Zaretskii <eliz@gnu.org>
273 * w32.c (opendir): Now accepts a 'const char *'.
275 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
277 Remove obsolete redisplay code. See the discussion at
278 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
279 * dispnew.c (preemption_period, preemption_next_check): Remove.
280 (Vredisplay_preemption_period): Likewise.
281 (update_frame, update_single_window, update_window, update_frame_1):
282 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
283 used, following the 2012-06-22 change.
285 2013-01-25 Eli Zaretskii <eliz@gnu.org>
287 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
289 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
291 * font.c (num_fonts): Remove the leftover from old
292 debugging code. Adjust comment style here and there.
293 * insdel.c (insert_1): Remove.
294 * lisp.h (insert_1): Remove prototype.
295 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
297 2013-01-25 Eli Zaretskii <eliz@gnu.org>
299 * w32.c (max_filename_mbslen): New function.
300 (normalize_filename, readdir): Use it to detect locales where ANSI
301 encoding of file names uses a double-byte character set (DBCS).
302 If a DBCS encoding is used, advance by characters using
303 CharNextExA, instead of incrementing a 'char *' pointer. Use
304 _mbslwr instead of _strlwr. (Bug#13515)
306 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
307 request of memory reservation to 1.7GB. (Bug#13065)
309 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
311 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
312 at check_extra_latin label. (Bug#13505)
314 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
316 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
317 Avoid redundant calls to strlen.
319 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
321 Drop async_visible and async_iconified fields of struct frame.
322 This is possible because async input is gone; for details, see
323 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
324 * frame.h (struct frame): Remove async_visible and async_iconified
325 members, convert garbaged to unsigned bitfield. Adjust comments.
326 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
327 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
328 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
329 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
330 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
332 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
333 properly. Likewise for obscured.
335 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
338 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
340 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
342 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
343 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
345 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
347 * xdisp.c (message2, message2_nolog): Remove functions.
348 (message3, message3_nolog): Extract nbytes and multibyteness directly
349 from the string. Change all callers.
350 (message3_nolog): Don't set message_enable_multibyte since set_message
351 will reset it anyway.
352 (message1, message1_nolog): Use message3.
353 (vmessage): Use a stack allocated buffer rather than f->message_buf.
354 (with_echo_area_buffer): Remove last two arguments. Update all callers.
355 (set_message): Drop all but the second arg, which has to be a string.
356 (set_message_1): Simplify now that we know that a1 is NULL and the
357 second arg is a string.
358 * frame.h (struct frame): Remove `message_buf' field.
359 Use glyphs_initialized_p instead.
360 (FRAME_MESSAGE_BUF): Remove macro.
361 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
362 * lisp.h (message2, message2_nolog): Remove declarations.
363 (message3, message3_nolog): Update declarations.
364 * keyboard.c (read_char_minibuf_menu_text)
365 (read_char_minibuf_menu_width): Remove vars.
366 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
367 to correctly handle multibyte strings.
368 * frame.c (delete_frame): Don't free message_buf any more.
369 * editfns.c (message_text, message_length): Remove vars.
370 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
371 * fileio.c (auto_save_error): Use message3 instead of message2.
372 * dispnew.c (adjust_frame_message_buffer): Remove function.
374 2013-01-23 Eli Zaretskii <eliz@gnu.org>
376 * w32term.c (w32fullscreen_hook): Account correctly for the screen
377 real estate used for the tool bar and the menu bar.
379 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
381 * insdel.c (prepare_to_modify_buffer): Force redisplay if
382 hidden buffer is prepared to modification (Bug#13164).
384 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
386 * window.h (struct window): Change window_end_valid member from
387 Lisp_Object to a bitfield. Adjust comments.
388 (wset_window_end_valid): Remove.
389 * window.c (adjust_window_count): Clear window_end_valid.
390 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
391 (Fwindow_line_height, set_window_buffer, Frecenter)
392 (Fsplit_window_internal, Fdelete_other_windows_internal)
393 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
394 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
395 * xdisp.c (check_window_end, reconsider_clip_changes)
396 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
397 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
398 (find_first_unchanged_at_end_row, try_window_id): Likewise.
400 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
402 * xdisp.c (mark_window_display_accurate): Simplify the loop
403 assuming that the only one of vchild, hchild or buffer window
404 slots is non-nil. Call mark_window_display_accurate_1 for
405 the leaf windows only.
406 (mark_window_display_accurate_1): Always assume leaf window.
409 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
411 * emacs.c (Qkill_emacs_hook): Now static.
413 * fileio.c (Finsert_file_contents): Simplify.
414 Remove unnecessary assignments and tests.
416 2013-01-21 Eli Zaretskii <eliz@gnu.org>
418 * w32.c (acl_set_file): Don't test for errors unless
419 set_file_security returns FALSE. Avoids spurious errors when
422 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
424 * fileio.c (Finsert_file_contents): Revert code introduced at
425 2013-01-18 in favor of the simpler and generally better fix.
426 Save stack space by removing 'buffer' and reusing 'read_buf'
429 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
431 * lisp.h (eabs): Define unconditionally (Bug#13419).
432 The old "#if !defined (eabs)" was an unnecessary revenant of back
433 when this macro was called "abs". Document 'eabs' better.
435 2013-01-19 Glenn Morris <rgm@gnu.org>
437 * fns.c (Frandom): Doc fix.
439 2013-01-19 Eli Zaretskii <eliz@gnu.org>
441 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
442 segfault when there are lots of overlays.
444 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
445 when there are lots of overlays. See
446 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
447 for the details and a way to reproduce.
449 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
451 * fileio.c: Use O_APPEND to append.
452 This corresponds better to the natural interpretation of "append",
453 and avoids the need to open the output file twice, or to invoke
454 lseek when APPEND is neither nil nor a number.
455 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
456 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
457 file possibly twice, and lseeking to its end; this avoids the
458 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
459 at the same time: the combination is never needed and apparently
460 it doesn't work with DOS_NT.
462 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
463 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
465 Allow floating-point file offsets.
466 Problem reported by Vitalie Spinu in
467 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
468 * fileio.c (emacs_lseek): Remove.
469 (file_offset): New function.
470 (Finsert_file_contents, Fwrite_region): Use it.
472 2013-01-19 Chong Yidong <cyd@gnu.org>
474 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid

484 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
486 Work around bug in CIFS and vboxsf file systems (Bug#13149).
487 The bug was observed on Ubuntu operating inside a virtual machine,
488 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
489 The workaround introduces a race condition on non-buggy hosts,
490 but it's an unlikely race and anyway there's a nearly identical
491 nearby race that can't be fixed.
492 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
494 (Fwrite_region): Test for file system time stamp bug.

511 gap and end positions after each read and so help make_gap to work
512 properly. Do not signal an I/O error too early and so do not leave
513 not yet decoded characters in a buffer, which was the reason of
514 redisplay crash. Use list2 to build return value. Adjust comments.
516 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
518 Close a race when statting and reading files (Bug#13149).
519 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
520 This avoids a race if the file is renamed between stat and open.
521 This race is not the problem originally noted in Bug#13149;
522 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

623 (save_excursion_restore): Adjust to match new layout. Use free_misc
624 because we do not allocate extra memory any more. Add eassert.
625 * print.c (print_object): New code to print Lisp_Save_Value. Do not
626 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

956 * xterm.h (struct x_output): Remove toolbar_detached member since it's
958 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
959 (xg_create_tool_bar): Adjust users.
961 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
963 * buffer.h (BUF_COMPACT): New macro to follow the common style.
964 * buffer.c (Fget_buffer_create): Use it to set compact field of
965 struct buffer_text to avoid accessing an uninitialized value
966 when compact_buffer is called for the first time.
967 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
968 (Fset_buffer_modified_p): Use buffer_window_count to check
969 whether the buffer is displayed in some window.
970 * xdisp.c (message_dolog): Likewise.
972 2012-12-23 Eli Zaretskii <eliz@gnu.org>
974 * w32.c (acl_set_file): If setting the file security descriptor
975 fails, and the new DACL is identical to the existing one, silently
976 return success. This fixes problems for users backing up their
977 own files without having the necessary privileges for setting
978 security descriptors.
980 * w32proc.c (reader_thread): Do not index fd_info[] with negative
982 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
983 after WaitForSingleObject returns normally. This expedites reader
984 thread shutdown when delete_child triggers it.
985 (reap_subprocess): More accurate commentary for why we call
986 delete_child only when cp->fd is negative.
988 * w32.c (sys_close): Do not call delete_child on a subprocess
989 whose handle is not yet closed. Instead, set its file descriptor
990 to a negative value, so that reap_subprocess will call
991 delete_child on that subprocess when its SIGCHLD arrives.
992 This avoids closing handles used for communications between sys_select
993 and reader_thread, which doesn't give sys_select a chance to
994 notice that the process exited and invoke the SIGCHLD handler for
997 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
999 * nsfns.m (Fns_do_applescript): Run event loop until script has
1000 been executed (Bug#12969).
1001 (ns_run_ascript): Chech as_script for nil, set to nil after
1004 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1006 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1008 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1010 * w32term.c (w32fullscreen_hook): New function.
1011 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1013 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1015 * fileio.c (Finsert_file_contents): Doc fix.
1017 * w32proc.c (new_child, delete_child, find_child_pid): For a
1018 subprocess, consider its slot being in use as long as its process
1019 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1020 slot when a new process is started immediately after killing
1021 another one, without waiting enough time for the first process to
1022 be reaped and resources allocated for it be orderly freed.
1024 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1026 2012-12-21 Chong Yidong <cyd@gnu.org>
1028 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1030 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1032 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1034 * w32.c (get_name_and_id): Always pass NULL as the first argument
1035 of lookup_account_sid. Avoids crashes with UNC file names that
1036 refer to DFS domains, not to specific machine names. (Bug#12621)
1037 Remove now unused argument FNAME; all callers changed.
1038 (get_file_owner_and_group): Remove now unused argument FNAME; all
1041 2012-12-21 Chong Yidong <cyd@gnu.org>
1043 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1044 error for invalid chars, don't check for a nil return value.
1046 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1048 Avoid calls to CHAR_TO_BYTE if byte position is known.
1049 * editfns.c (make_buffer_string_both): Use move_gap_both.
1050 (Fbuffer_string): Use make_buffer_string_both.
1051 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1053 (buf_bytepos_to_charpos): Likewise.
1054 (charpos_to_bytepos): Remove.
1055 * fileio.c (Finsert_file_contents): Use move_gap_both.
1056 * search.c (Freplace_match): Likewise.
1057 * process.c (process_send_region): Likewise. Use convenient
1058 names for byte positions.
1059 * lisp.h (charpos_to_bytepos): Remove prototype.
1060 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1061 * insdel.c (move_gap): Likewise.
1063 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
1065 * xdisp.c (redisplay_internal): Remove now-unused local.
1067 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1069 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1070 (redisplay_internal): Don't bother selecting the frame to get the
1071 proper value of frame-local variables (bug#13225).
1073 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1075 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1076 Rename 4th argument since it may be buffer or string. Adjust comment.
1077 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1079 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1081 * coding.c (Fdetect_coding_region): Do not check start and end with
1082 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1083 (code_convert_region): Likewise.
1085 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1087 * w32.c (acl_get_file, acl_set_file): Run the file name through
1088 map_w32_filename, and resolve any symlinks in the file name, like
1090 (acl_set_file): Call revert_to_self, if any privileges were
1093 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1095 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1096 ($(BLD)/w32.$(O)): Update dependencies.
1098 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1100 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1101 propagate redisplay's scrolling (if any) to the right window.
1102 (redisplay_internal): Use ensure_selected_frame.
1103 (display_mode_lines): Complete last fix.
1104 * window.c (select_window_1): New func, extracted from select_window.
1105 (select_window): Use it.
1106 * window.h (select_window_1): Declare.
1108 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1110 Emulate Posix ACL APIs on MS-Windows.
1111 * w32.c: Include sddl.h and sys/acl.h.
1112 (SDDL_REVISION_1): Define if not already defined.
1113 (g_b_init_get_security_descriptor_dacl)
1114 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
1115 (g_b_init_is_valid_security_descriptor)
1116 (g_b_init_set_file_security): New static flags.

1128 (acl_free, acl_get_file, acl_set_file): New functions.
1130 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1132 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1134 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1135 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1136 for some of that bug's symptoms can now cause Emacs to abort.
1137 Remove the workaround.
1138 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1139 The bug that caused SIGCHLD to get lost has been fixed, and the
1140 workaround for it can now cause Emacs to abort.
1142 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1144 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1145 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1146 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1148 2012-12-16 Romain Francoise <romain@orebokech.com>
1150 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1151 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1152 and copy ACL entries of file in addition to SELinux context if set.
1153 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1155 * Makefile.in (LIBACL_LIBS): New macro.
1158 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
1160 * fileio.c (internal_delete_file): Use bool for boolean.
1162 2012-12-15 Eli Zaretskii <eliz@gnu.org>
1164 Fix bug #13079 on MS-Windows with temp files not being deleted.

1167 (register_child): First argument is now pid_t.
1168 (record_infile, record_pending_deletion): New prototypes.
1170 * w32proc.c (new_child): Initialize input_file and
1171 pending_deletion members of the child.
1172 (delete_child): Delete the child's temporary input file, if any,
1173 that is pending deletion.
1174 (register_child): First argument is now pid_t.
1175 (record_infile, record_pending_deletion): New functions.
1176 (reap_subprocess): Fix a typo in DebPrint string.
1177 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1179 * fileio.c (internal_delete_file): Return an int again: non-zero
1180 if delete-file succeeds, zero otherwise.
1182 * lisp.h (internal_delete_file): Adjust prototype.
1184 * callproc.c (Fcall_process): Don't overwrite infile with result
1186 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1187 asynchronous subprocess, record the name of the input file name,
1189 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1190 delete the file, record it as pending deletion when the subprocess
1193 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1195 * editfns.c [HAVE_PWD_H]: Include grp.h.
1197 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1199 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1201 Fix permissions bugs with setgid directories etc. (Bug#13125)
1202 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1203 to mark it as a placeholder. The old value was often wrong.
1204 The only user of this attribute has been changed to use
1205 file-ownership-preserved-p instead, with its new group arg.
1206 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1208 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

1213 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1215 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1216 try to get accurate owner and group information from NT file
1217 security APIs. This is to make most callers of 'stat' and
1218 'lstat', which don't need that information, much faster.
1220 * dired.c (Ffile_attributes) [WINDOWSNT]:
1221 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1222 owner and group information from 'lstat'.
1224 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1226 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1227 as that confuses set-auto-coding, so insist on the head-read
1228 returning the full 1024 bytes. Let lseek compute the tail offset;
1229 less work for us. Do not ignore I/O errors when reading the tail.
1231 * xdisp.c: Minor style fixes.
1232 (init_iterator): Hoist assignment out of if-expression.
1233 (markpos_of_region): Callers now test for sign, not for -1.

1238 * xdisp.c (markpos_of_region): New function.
1239 (init_iterator): Do not highlight the region of zero length.
1240 (redisplay_window): Check whether the region is of non-zero length.
1241 (try_cursor_movement): Allow if the region length is zero.
1242 (try_window_reusing_current_matrix, try_window_id): Likewise.
1244 2012-12-13 Eli Zaretskii <eliz@gnu.org>
1246 * search.c (search_buffer): Check the inverse translations of each
1247 character in pattern when the buffer being searched is unibyte.
1250 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1252 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1253 files, fixing a regression from 24.2.
1254 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1256 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1258 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1259 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1260 Remove unnecessary S_ISLNK test, as (contra the comments) this
1261 function can't copy symlinks. Improve quality of error message
1262 when attempting to copy files that are neither regular files nor

1270 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1271 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1273 2012-12-12 Daniel Colascione <dancol@dancol.org>
1275 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1276 the dumped Emacs is not a sparse file, greatly improving Cygwin
1277 "make bootstrap" performance.
1279 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1281 * inotify.c (inotify_callback): Generate an Emacs event for every
1282 incoming inotify event.
1284 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1286 * xdisp.c (handle_face_prop): Fix logic of computing
1287 it->start_of_box_run_p.
1288 (append_space_for_newline): If the glyph row is R2L, reset the
1289 iterator's end_of_box_run_p flag before prepending the space glyph.
1290 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1291 iterator's start_of_box_run_p flag before prepending the stretch.
1292 (append_glyph, produce_image_glyph, append_composite_glyph)
1293 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1294 left_box_line_p and right_box_line_p flags of the glyph for R2L
1295 glyph rows. (Bug#13011)
1297 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1302 * window.c (replace_buffer_in_windows_safely): Do nothing
1303 if buffer is not shown in a window.

1309 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1310 encoded_file_name, which is what it is.
1312 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1314 Consistently use marker_position and marker_byte_position.
1315 * fringe.c (Ffringe_bitmaps_at_pos):

1323 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
1324 Replace direct access to marker fields with calls
1325 to marker_position and/or marker_byte_position.

1338 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1341 * w32fns.c (cache_system_info): Initialize the global hinst
1342 variable here so various initialization calls DTRT.
1344 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1345 (hinst): Remove unneeded extern declaration.
1346 (_start): Remove initialization of above variables; remove
1347 initialization of hinst, as cache_system_info now does that.

1456 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
1458 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
1460 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
1461 DWORD_PTR, for compatibility with 64-bit builds.
1463 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
1464 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
1465 (system_process_attributes): Use SIZE_T rather than DWORD, for
1466 compatibility with 64-bit builds.

1472 2012-12-10 Eli Zaretskii <eliz@gnu.org>
1474 * indent.c (Fvertical_motion): If a display string will be
1475 displayed on the left or the right margin, don't consider it as a
1476 factor in cursor positioning. (Bug#13108)
1478 2012-12-10 Martin Rudalics <rudalics@gmx.at>
1480 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
1482 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>

1487 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1489 * w32.c (unsetenv): Return 0 if the input string is too long.
1491 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1493 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1494 * alloc.c (xputenv): New function.
1495 * dbusbind.c (Fdbus_init_bus):
1497 * xterm.c (x_term_init):
1498 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

1500 (tzvalbuf_in_environ): New static var.
1501 (init_editfns): Initialize these two static vars.
1502 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1503 Save old TZ value on stack, if it's small.
1504 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1505 instead, use xputenv+unsetenv to set and restore TZ.
1506 (environbuf): Remove static var. All uses removed.
1507 (Fset_time_zone_rule): Do not save TZ and environ;
1508 no longer needed here.
1509 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1510 Move to inside set_time_zone_rule; they don't need file scope any more.
1511 (set_time_zone_rule): Maintain the TZ=value string separately.
1512 (syms_of_editfns): Don't initialize initial_tz;
1513 init_editfns now does it.
1514 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1515 * lisp.h (xputenv): New decl.
1517 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1519 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1521 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1523 * w32.c (unsetenv, sys_putenv): New functions.
1525 2012-12-08 Chong Yidong <cyd@gnu.org>
1527 * editfns.c (Finsert_char): Make the error message more
1528 informative (Bug#12992).
1530 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1532 Simplify get_lim_data.
1533 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1534 Remove USG and vlimit methods; no longer used these days.
1535 Add #error catchall just in case.
1537 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1538 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1539 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1540 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1541 (deleted_pid_list, Fdelete_process, create_process)
1542 (record_child_status_change, handle_child_signal, deliver_child_signal)
1543 (init_process_emacs, syms_of_process):
1544 Assume SIGCHLD is defined.
1545 (parse_signal): Remove. All uses removed.
1546 (abbr_to_signal): New static function.
1547 (Fsignal_process): Use it to convert signal names to ints.
1548 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1549 kill (getpgrp (), ...).
1550 (emacs_sigaction_init): Assume SIGCHLD is defined.
1551 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1552 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.

1554 All uses replaced by 'kill' with a negative pid.
1555 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1556 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1558 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1560 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1561 This will cause a production Emacs to dump core instead of
1564 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1566 * frame.c (make_frame): Do not set window's buffer to t.
1567 * window.c (Fsplit_window_internal): Likewise. Previously it was
1568 used to indicate that the window is being set up. Now we use
1569 set_window_buffer for all new windows, so the condition in ...
1570 (Fset_window_buffer): ... is always true and can be removed.
1572 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1574 Convenient macro to check whether the buffer is hidden.
1575 * buffer.h (BUFFER_HIDDEN_P): New macro.
1576 * frame.c (make_frame): Use it. Adjust comment.
1577 * buffer.c (candidate_buffer): New function.
1578 (Fother_buffer, other_buffer_safely): Use it.
1580 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1582 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1583 if the child process is still running. Instead, exit the wait
1584 loop and return zero. (Bug#13086)
1586 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1588 * frame.h (x_char_width, x_char_height): Remove prototypes.

1601 Fix a recently-introduced delete-process race condition.
1602 * callproc.c, process.h (record_kill_process):
1603 New function, containing part of the old call_process_kill.
1604 (call_process_kill): Use it.
1605 This does not change call_process_kill's behavior.
1606 * process.c (Fdelete_process): Use record_kill_process to fix a
1607 race condition that could cause Emacs to lose track of a child.
1609 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1611 Avoid code duplication between prev_frame and next_frame.
1612 * frame.c (candidate_frame): New function. Add comment.
1613 (prev_frame, next_frame): Use it. Adjust comment.
1615 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1617 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1618 fails, signal an error instead of continuing with an empty
1620 Encode expanded temp file pattern before passing it to mkstemp or
1623 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1624 Encode the file name before passing it to dostounix_filename, in
1625 case it will downcase it (under w32-downcase-file-names).
1628 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1630 Minor call-process cleanups.
1631 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1632 at the same time as other platforms, to simplify analysis.
1633 No need for fd0_volatile since we have synch_process_fd.
1634 Avoid needless emacs_close; arg is always negative.
1636 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1638 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1641 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1643 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1644 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1645 and mouse_face_hidden members to a bitfields.
1646 * frame.h (struct frame): Remove set-but-not-used space_width member.
1647 (FRAME_SPACE_WIDTH): Remove.
1648 * nsterm.m, w32term.c, xterm.c: Adjust users.
1649 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1650 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1651 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1652 members to a bitfields.
1654 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1656 Don't let call-process be a zombie factory (Bug#12980).
1657 Fixing this bug required some cleanup of the signal-handling code.
1658 As a side effect, this change also fixes a longstanding rare race
1659 condition whereby Emacs could mistakenly kill unrelated processes,
1660 and it fixes a bug where a second C-g does not kill a recalcitrant
1661 synchronous process in GNU/Linux and similar platforms.
1662 The patch should also fix the last vestiges of Bug#9488,
1663 a bug which has mostly been fixed on the trunk by other changes.
1664 * callproc.c, process.h (synch_process_alive, synch_process_death)
1665 (synch_process_termsig, sync_process_retcode):
1666 Remove. All uses removed, to simplify analysis and so that
1667 less consing is done inside critical sections.
1668 * callproc.c (call_process_exited): Remove. All uses replaced
1669 with !synch_process_pid.
1670 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1671 These take the role of what used to be in unwind-protect arg.
1673 (block_child_signal, unblock_child_signal):
1674 New functions, to avoid races that could kill innocent-victim processes.
1675 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1676 (call_process_kill): Record killed processes as deleted, so that
1677 zombies do not clutter up the system. Do this inside a critical
1678 section, to avoid a race that would allow the clutter.
1679 (call_process_cleanup): Fix code so that the second C-g works again
1680 on common platforms such as GNU/Linux.
1681 (Fcall_process): Create the child process in a critical section,
1682 to fix a race condition. If creating an asynchronous process,
1683 record it as deleted so that zombies do not clutter up the system.
1684 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1685 light of these changes. Omit unnecessary call to emacs_close
1686 before failure, as the unwind-protect code does that.
1687 * callproc.c (call_process_cleanup):
1688 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1689 * process.c (record_deleted_pid): New function, containing
1690 code refactored out of Fdelete_process.
1691 (Fdelete_process): Use it.
1692 (process_status_retrieved): Remove. All callers changed to use
1693 child_status_change.
1694 (record_child_status_change): Remove, folding its contents into ...
1695 (handle_child_signal): ... this signal handler. Now, this
1696 function is purely a handler for SIGCHLD, and is not called after
1697 a synchronous waitpid returns; the synchronous code is moved to
1698 wait_for_termination. There is no need to worry about reaping
1699 more than one child now.
1700 * sysdep.c (get_child_status, child_status_changed): New functions.
1701 (wait_for_termination): Now takes int * status and bool
1702 interruptible arguments, too. Do not record child status change;
1703 that's now the caller's responsibility. All callers changed.
1704 Reimplement in terms of get_child_status.
1705 (wait_for_termination_1, interruptible_wait_for_termination):
1706 Remove. All callers changed to use wait_for_termination.
1707 * syswait.h: Include <stdbool.h>, for bool.
1708 (record_child_status_change, interruptible_wait_for_termination):
1710 (record_deleted_pid, child_status_changed): New decls.
1711 (wait_for_termination): Adjust to API changes noted above.
1713 * bytecode.c, lisp.h (Qbytecode): Remove.
1714 No longer needed after 2012-11-20 interactive-p changes.
1716 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1718 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1719 the scroll margin, move point outside the margin. (Bug#13055)
1721 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1723 * gtkutil.c (my_log_handler): New function.
1724 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1726 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1728 * lisp.h (modify_region): Rename to...
1729 (modify_region_1): ...new prototype.
1730 * textprop.c (modify_region): Now static. Adjust users.
1731 * insdel.c (modify_region): Rename to...
1732 (modify_region_1): ...new function to work with current buffer.
1733 Adjust comment and users. Use true and false for booleans.
1735 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1737 * alloc.c (free_save_value): New function.
1738 (safe_alloca_unwind): Use it.
1739 * lisp.h (free_save_value): New prototype.
1740 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1742 (save_excursion_restore): Adjust to match saved data structure.
1743 Use free_save_value to offload some work from GC. Drop obsolete
1746 2012-12-03 Chong Yidong <cyd@gnu.org>
1748 * fileio.c (Vauto_save_list_file_name): Doc fix.
1750 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1752 * w32fns.c: Remove prototype of atof.
1753 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1755 (file_dialog_callback): Make it UINT_PTR.
1757 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1760 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1761 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1764 2012-12-03 Glenn Morris <rgm@gnu.org>
1766 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1768 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1770 Fix xpalloc confusion after memory is exhausted.
1771 * alloc.c (xpalloc): Comment fix.
1772 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1773 and signals an error, do not clear charset_table_size, as
1774 charset_table is still valid.
1775 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1777 Use execve to avoid need to munge environ (Bug#13054).
1778 * callproc.c (Fcall_process):
1779 * process.c (create_process):
1780 Don't save and restore environ; no longer needed.
1781 * callproc.c (child_setup):
1782 Use execve, not execvp, to preserve environ.
1784 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1786 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1788 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1790 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1791 display for sliced images (Bug#10500).
1793 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1795 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1797 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1798 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1800 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1802 * xdisp.c (window_outdated): Remove eassert since it hits
1803 some suspicious corner cases (see Bug#13007 and Bug#13012).
1804 (mode_line_update_needed): New function.
1805 (redisplay_internal, redisplay_window): Use it.
1806 (ensure_selected_frame): New function.
1807 (redisplay_internal, unwind_redisplay): Use it.
1808 (redisplay_internal): Move comment about buffer_shared...
1809 (buffer_shared_and_changed): ...near to its real use.
1811 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1813 * callproc.c (Fcall_process): Don't misreport vfork failure.
1815 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1817 * callproc.c (Fcall_process): Fix vfork portability problems.
1818 Do not assume that fd[0], count, filefd, and save_environ survive
1819 vfork. Fix bug whereby wrong errno value could be reported for
1820 pipe failure. Some minor cleanups, too, as follows. Move buf and
1821 bufsize to the context where they're needed. Change new_argv to
1822 be of type char **, as this is more convenient and avoids casts.
1823 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1824 Now local constants, not macros.
1826 2012-11-18 Kenichi Handa <handa@gnu.org>
1828 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1829 for the variable "f".
1831 2012-11-13 Kenichi Handa <handa@gnu.org>
1833 * font.c (font_unparse_xlfd): Exclude special characters from the
1834 generating XLFD name.
1836 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1838 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
1839 * dired.c (stat_uname, stat_gname):
1840 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1842 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1844 Assume EAGAIN and EINTR are defined.
1846 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1847 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1848 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1849 * lread.c (readbyte_from_file): Assume EINTR is defined.
1850 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1851 Assume EIO and EAGAIN are defined.
1852 * unexcoff.c (write_segment): Assume EFAULT is defined.
1854 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1856 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1859 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1860 highlighting on the frame was cleared. Prevents assertion
1861 violations when repeatedly clicking on the "Top" link of the
1862 "bread-crumbs" in Info buffers.
1864 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1866 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1868 2012-11-24 Ken Brown <kbrown@cornell.edu>
1870 * keyboard.c (HAVE_MOUSE):
1871 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1872 were always defined.
1874 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1876 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1877 between bpos_covered and bpos_max. This fixes cursor display when
1878 several display strings follow each other.
1880 * .gdbinit (pgx): If the glyph's object is a string, display the
1881 pointer to string data, rather than the value of the string object
1882 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1884 * indent.c (Fvertical_motion): If the starting position is covered
1885 by a display string, return to one position before that, to avoid
1886 overshooting it inside move_it_to. (Bug#12930)
1888 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1890 * frame.h (struct frame): Remove display_preempted member

1893 * w32menu.c (pending_menu_activation): Remove since not
1895 (set_frame_menubar): Adjust user.
1896 * w32term.h (struct x_output): Drop outdated #if 0 code.
1897 (struct w32_output): Use bitfields for explicit_parent,
1898 asked_for_visible and menubar_active members.
1899 Drop unused pending_menu_activation member.
1900 * xterm.h (struct x_output): Drop outdated #if 0 code.
1901 Use bitfields for explicit_parent, asked_for_visible,
1902 has_been_visible and net_wm_state_hidden_seen members.
1904 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1906 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1907 of a literal "/". (Bug#12955)
1908 (gl-stamp): Invoke fc.exe directly, not through cmd.
1910 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1912 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1913 * dired.c: Assume HAVE_DIRENT_H.
1914 (NAMLEN): Remove, replacing with ...
1915 (dirent_namelen): New function. All uses changed. Use the GNU macro
1916 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1917 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1918 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1919 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1921 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1922 * ndir.h: Rename to ../nt/inc/dirent.h.
1923 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1924 Do not include <dirent.h>; no longer needed.
1925 * w32.c: Include <dirent.h> rather than "ndir.h".
1927 2012-11-23 Chong Yidong <cyd@gnu.org>
1929 * xftfont.c (xftfont_open): Remove duplicate assignment.
1931 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1933 * alloc.c (Fgarbage_collect): Unblock input after clearing
1934 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1935 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1936 * msdos.c (IT_frame_up_to_date): Use it here...
1937 * w32term.c (w32_frame_up_to_date): ...here...
1938 * xterm.c (XTframe_up_to_date): ...and here...
1939 * nsterm.m (ns_frame_up_to_date): ...but not here.
1940 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1942 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1943 Do not check whether GC is in progress.
1945 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1947 * xdisp.c (window_buffer_changed): New function.
1948 (update_menu_bar, update_tool_bar): Use it to
1949 simplify large 'if' statements.
1950 (redisplay_internal): Generalize commonly used
1951 'tail' and 'frame' local variables.
1953 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1955 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1956 with Windows system header.
1958 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1960 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1961 * alloc.c: Assume unistd.h exists.
1962 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1963 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1964 (getwd) [USG]: Remove; no longer needed.
1965 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1966 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1967 * w32.h (getcwd): Remove decl.
1969 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1971 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1972 Make it set selected_window as well.
1973 (update_tool_bar): Use it.
1975 2012-11-21 Ken Brown <kbrown@cornell.edu>
1977 * emacs.c (main): Set the G_SLICE environment variable for all
1978 Cygwin builds, not just GTK builds. See
1979 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1981 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1983 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1984 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1985 Define for the MSVC compiler.
1987 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1989 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1990 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1991 dostounix_filename. Prevents crashes down the road, because
1992 dostounix_filename assumes it gets a unibyte string.
1993 Reported by Michel de Ruiter <michel@sentient.nl>, see
1994 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1996 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

2000 * lread.c (init_obarray): Set `function' fields to Qnil.
2001 * eval.c (Fcommandp): Ignore Qunbound.
2002 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2003 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2004 Test NILP rather than Qunbound.
2005 (Ffmakunbound): Set to Qnil.
2006 (Fsymbol_function): Never signal an error.
2007 (Finteractive_form): Ignore Qunbound.
2009 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2011 * eval.c (interactive_p): Remove no-longer-used decl.
2013 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2015 * xdisp.c (buffer_shared): Adjust comment.
2016 (buffer_shared_and_changed): New function.
2017 (prepare_menu_bars, redisplay_internal): Use it to
2018 decide whether all windows or frames should be updated.
2019 (window_outdated): New function.
2020 (text_outside_line_unchanged_p, redisplay_window): Use it.
2021 (redisplay_internal): Likewise. Fix indentation.
2023 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2025 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2026 (syms_of_eval): Remove corresponding defsubr.
2027 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2029 2012-11-19 Daniel Colascione <dancol@dancol.org>
2031 * w32fns.c (Fx_file_dialog):
2032 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2033 cygwin_convert_file_name*.
2035 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2036 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2038 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2040 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2042 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2044 * w32select.c: Include w32common.h before w32term.h, so that
2045 windows.h gets included before w32term.h uses some of its
2046 features, see below.
2048 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2050 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2052 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2054 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2056 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2057 (ns_select): Return at once if events are held (Bug#12834).
2059 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2061 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2062 Needed following 2012-10-20 change. (Bug#12902)
2064 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2066 * w32proc.c (waitpid): Remove unused label get_result.
2068 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2070 * makefile.w32-in (SYSWAIT_H): New macro.
2071 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2072 ($(BLD)/sysdep.$(O)): Update dependencies.
2074 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2076 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2077 * callproc.c (relocate_fd): Assume F_DUPFD.
2078 * emacs.c, term.c (O_RDWR): Remove.
2079 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2080 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2081 * nsterm.m: Assume <fcntl.h> exists.
2082 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2083 (create_pty, Fmake_network_process, server_accept_connection)
2084 (wait_reading_process_output, init_process_emacs):
2086 (wait_reading_process_output): Put in a special case for WINDOWSNT
2087 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2088 It's not clear this is needed, but it's a more-conservative change.
2089 (create_process): Assume FD_CLOEXEC.
2090 (create_process, create_pty): Assume O_NOCTTY.
2091 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2092 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2093 Omit if not DOS_NT, since F_GETFL is not defined there.
2094 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2095 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2097 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2098 lack it, since gnulib guarantees this.
2099 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2101 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2103 * w32.c (faccessat): Pretend that directories have the execute bit
2104 set. Emacs expects that, e.g., in files.el:cd-absolute.
2106 * w32proc.c (create_child): Don't clip the PID of the child
2107 process to fit into an Emacs integer, as this is no longer a
2109 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2110 reaping only the process specified by PID argument, if that is
2111 positive. Use PID instead of dead_child to know which process to
2112 reap. Wait for the child to die only if WNOHANG is not in
2114 (sys_select): Don't set dead_child.
2116 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2117 as it is no longer needed.
2119 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2121 (record_child_status_change): Remove the setting of
2122 record_at_most_one_child for the !WNOHANG case.
2124 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2126 Fix problems in ns port found by static checking.
2127 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2128 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2129 not to process group.
2130 (ns_select): Use emacs_write, not write, as that's more robust
2131 in the presence of signals.
2132 (fd_handler:): Check for read errors.
2134 2012-11-16 Glenn Morris <rgm@gnu.org>
2136 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2138 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2140 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2142 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2144 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2145 use the same value of thread handle.
2146 (start_timer_thread): If the timer thread exited (due to error),
2147 clean up by closing the two handles it used. Duplicate the caller
2148 thread's handle here, so it gets duplicated only once, when
2149 launching the timer thread. Set priority of the timer thread, not
2151 (getitimer): Don't duplicate the caller thread's handle here.
2154 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2156 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2159 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2161 Remove no-longer-used pty_max_bytes variable.
2162 * process.c (pty_max_bytes): Remove; unused.
2163 (send_process): Do not set it.
2165 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2167 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2168 Update dependencies.
2170 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2172 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2173 This follows up on the 2012-09-29 patch that removed indirection
2174 for the 'function' field. Reported by Sergey Vinokurov in
2175 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2177 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2179 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2180 different name, as the MS runtime does not have such a function,
2181 and probably never will.) All callers changed. Ignore DIRFD
2182 value if PATH is an absolute file name, to match Posix spec
2183 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2186 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2188 * xdisp.c (echo_area_display, redisplay_internal):
2189 Omit redundant check whether frame_garbaged is set.
2191 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2193 Use faccessat, not access, when checking file permissions (Bug#12632).
2194 This fixes a bug that has been present in Emacs since its creation.
2195 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2196 which must set some sort of record. (Torek's bug report was against
2197 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2198 same common flaw.) See Torek's Usenet posting
2199 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2200 Posted: Fri Apr 8 14:18:56 1983.
2201 * Makefile.in (LIB_EACCESS): New macro.
2203 * callproc.c (init_callproc):
2204 * charset.c (init_charset):
2205 * fileio.c (check_existing, check_executable, check_writable)
2207 * lread.c (openp, load_path_check):
2208 * process.c (allocate_pty):
2210 Use effective UID when checking permissions, not real UID.
2211 * callproc.c (init_callproc):
2212 * charset.c (init_charset):
2213 * lread.c (load_path_check, init_lread):
2214 Test whether directories are accessible, not merely whether they exist.
2215 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2216 * fileio.c (check_existing, check_executable, check_writable)
2218 Use symbolic names instead of integers for the flags, as they're
2220 (check_writable): New arg AMODE. All uses changed.
2221 Set errno on failure.
2222 (Ffile_readable_p): Use faccessat, not stat + open + close.
2223 (Ffile_writable_p): No need to call check_existing + check_writable.
2224 Just call check_writable and then look at errno. This saves a syscall.
2225 dir should never be nil; replace an unnecessary runtime check
2226 with an eassert. When checking the parent directory of a nonexistent
2227 file, check that the directory is searchable as well as writable, as
2228 we can't create files in unsearchable directories.
2229 (file_directory_p): New function, which uses 'stat' on most platforms
2230 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2231 (Ffile_directory_p, Fset_file_times): Use it.
2232 (file_accessible_directory_p): New function, which uses a single
2233 syscall for efficiency.
2234 (Ffile_accessible_directory_p): Use it.
2235 * xrdb.c (file_p): Use file_directory_p.
2236 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2237 * lread.c (openp): When opening a file, use fstat rather than
2238 stat, as that avoids a permissions race. When not opening a file,
2239 use file_directory_p rather than stat.
2240 (dir_warning): First arg is now a usage string, not a format.
2241 Use errno. All uses changed.
2242 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2243 that merely introduced a race.
2244 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2245 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2246 and similarly for the other O_* flags.
2247 * w32.c (sys_faccessat): Rename from sys_access and switch to
2248 faccessat's API. All uses changed.
2249 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2250 (magic_db): Rename from magic_file_p.
2251 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2252 char *, so that we don't have to test for file existence
2253 separately from opening the file for reading. This removes a race
2254 fixes a permission-checking problem, and simplifies the code.
2256 (file_p): Remove; no longer needed.
2258 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2260 Omit glyphs initialization at startup.
2261 * dispnew.c (glyphs_initialized_initially_p): Remove.
2262 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2263 (Fredraw_frame): Move actual code from here...
2264 (redraw_frame): ...to here. Add eassert. Adjust comment.
2265 (Fredraw_display): Use redraw_frame.
2266 * xdisp.c (clear_garbaged_frames): Likewise.
2268 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2270 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2271 passed to pint2str and pint2hrstr to be at most the size of the
2272 frame's decode_mode_spec_buffer. This avoids crashes with very
2273 large values of FIELD_WIDTH argument to decode_mode_spec.
2276 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2278 Fix a race with verify-visited-file-modtime (Bug#12863).
2279 Since at least 1991 Emacs has ignored an mtime difference of no
2280 more than one second, but my guess is that this was to work around
2281 file system bugs that were fixed long ago. Since the race is
2282 causing problems now, let's remove that code.
2283 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2284 whose time stamp is off by no more than a second. Insist that the
2285 file time stamps match exactly.
2287 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2289 * frame.h (struct frame): Convert external_tool_bar member to
2290 1-bit unsigned bitfield.
2291 * termhooks.h (struct terminal): Remove mouse_moved member since
2292 all users are long dead. Adjust comment on mouse_position_hook.
2294 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2296 Simplify by using FOR_EACH_FRAME here and there.
2297 * frame.c (next_frame, prev_frame, other_visible_frames)
2298 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2299 * w32term.c (x_window_to_scroll_bar): Likewise.
2300 * window.c (window_list): Likewise.
2301 * xdisp.c (x_consider_frame_title): Likewise.
2302 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2303 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2304 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2305 * xmenu.c (menubar_id_to_frame): Likewise.
2306 * xselect.c (frame_for_x_selection): Likewise.
2307 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2308 (x_window_to_menu_bar): Likewise.
2309 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2311 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2313 * data.c (Qdefalias_fset_function): Now static.
2315 Another tweak to vectorlike_header change.
2316 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2317 Remove, and replace all uses with ...
2318 (next_in_free_list, set_next_in_free_list):
2319 New functions, which respect C's aliasing rules better.
2321 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2323 * window.c (list4i): Rename from 'quad'. All uses changed.
2324 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2326 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2328 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2329 warning about mixing declarations and code in ISO C90.
2331 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2333 * window.c (Fsplit_window_internal): Set combination limit of
2334 new parent window to t iff Vwindow_combination_limit is t;
2335 fixing a regression introduced with the change from 2012-09-22.
2336 (Fset_window_combination_limit): Fix doc-string.
2338 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2340 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2341 amount when the scroll margins are too large. When scrolling
2342 backwards in the buffer, give up if cannot reach point or the
2343 scroll margin within a reasonable number of screen lines.

2345 point is positioned many lines beyond the window top/bottom.
2348 * ralloc.c (relinquish): If real_morecore fails to return memory
2349 to the system, don't crash; instead, leave the last heap

2361 (Qdefalias_fset_function): New var.
2363 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2365 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

2375 (SCROLL_BAR_VEC_SIZE): Remove.
2376 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2378 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2380 Tweak last vectorlike_header change.
2381 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2382 vectorlike object on the free list. This is introduced to avoid
2383 some (but not all) pointer casting and aliasing problems, see
2384 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2385 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

2389 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2391 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

2414 * lisp.h (sxhash_combine): New inline function, with the contents
2415 of the old SXHASH_COMBINE.
2416 * profiler.c (hashfn_profiler): Use it, instead of having a
2417 special hash function containing a comparison that always yields 1.
2419 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2421 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2422 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2423 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2426 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2428 * image.c (xpm_make_color_table_h): Fix compiler error because
2429 make_hash_table changed.
2431 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2433 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2435 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2437 Use ad-hoc comparison function for the profiler's hash-tables.
2438 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2439 (make_log): Use them.
2440 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2441 call Fequal any more.

2450 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2451 (hash_lookup, hash_remove_from_table): Move assertion checking of
2452 hashfn result here. Check hash-equality before calling cmpfn.

2464 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2465 value of w32-scroll-lock-modifier is neither nil nor one of the
2466 known key modifiers. (Bug#12806)
2468 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2470 Shrink struct vectorlike_header to the only size field.
2471 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2473 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2474 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2475 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2476 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2477 information from the vector header. Adjust comment.

2492 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2493 (large_vectors): Change type to struct large_vector.
2494 (allocate_vector_from_block): Simplify.
2495 (PSEUDOVECTOR_NBYTES): Replace with...
2496 (vector_nbytes): ...new function. Adjust users.
2497 (sweep_vectors): Adjust processing of large vectors.
2498 (allocate_vectorlike): Likewise.
2499 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2500 Add easserts. Adjust XSETPVECTYPESIZE usage.
2501 (allocate_buffer): Use BUFFER_PVEC_INIT.
2502 (live_vector_p): Adjust to match large vector.
2503 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2504 * buffer.h (struct buffer): Add next member.
2505 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2507 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

2513 (xvecsize): New command.
2515 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2517 * keyboard.c (event_to_kboard): Do not dereference
2518 frame_or_window field of SELECTION_REQUEST_EVENT
2519 and SELECTION_CLEAR_EVENT events (Bug#12814).
2520 * xterm.h (struct selection_input_event): Adjust comment.
2522 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2524 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2525 such as Scroll Lock, if the respective keys are treated as
2526 function keys, not as modifiers. This avoids destroying non-ASCII
2527 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2529 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2531 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2533 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2535 Restore some duplicate definitions (Bug#12814).
2536 This undoes part of the 2012-11-03 changes. Some people build
2537 with plain -g rather than with -g3, and they need the duplicate
2538 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2539 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2540 Define as macros, as well as as enums or as constants.
2542 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2544 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2545 to keypad keys (Bug#12816).
2547 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2549 Minor adjustments of recently-changed frame functions.
2550 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2551 known to be a frame (we're in the FRAMEP branch).
2552 * lisp.h (Qframep): Remove decl. frame.h declares this.
2553 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2554 since they're meant for Lisp fixnum values.
2556 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2558 * window.c (Fwindow_combination_limit): Revert to the only
2559 required argument and adjust docstring as suggested in
2560 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2561 by Martin Rudalics <rudalics@gmx.at>.
2563 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2565 Widely used frame validity and checking functions.
2566 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2567 * frame.c (decode_live_frame, decode_any_frame): New functions.
2568 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2569 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2570 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2571 (Fframe_pointer_visible_p): Use decode_any_frame.

2573 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2574 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2575 (Fframe_focus): Likewise. Allow zero number of arguments.
2577 (frame_buffer_list, frame_buffer_predicate): Remove.
2578 * lisp.h (frame_buffer_predicate): Remove prototype.
2579 * buffer.c (Fother_buffer): Use decode_any_frame.
2580 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2581 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2582 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2583 (Fclose_font, Ffont_info): Use decode_live_frame.
2584 * fontset.c (check_fontset_name): Likewise.
2585 * terminal.c (Fframe_terminal): Likewise.
2586 * w32fns.c (check_x_frame): Likewise.
2587 * window.c (Fminibuffer_window, Fwindow_at)
2588 (Fcurrent_window_configuration): Likewise.
2589 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2590 Likewise. Allow zero number of arguments. Adjust docstring.
2591 * dispnew.c (Fredraw_frame): Likewise.
2592 * xfaces.c (frame_or_selected_frame): Remove.
2593 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2594 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2595 (Fframe_face_alist): Use decode_live_frame.
2596 * xfns.c (check_x_frame): Likewise.
2598 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2600 * window.c (quad): New function.
2601 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2602 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2603 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2604 (Fwindow_line_height): Use it.
2605 (Fwindow_fringes): Use list3.
2606 (Fwindow_scroll_bars): Use list4.
2607 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2608 (Fwindow_combination_limit): Allow zero number of arguments.
2610 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2612 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2614 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2615 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2616 file descriptor 2 for standard error. (Bug#12805)
2618 2012-11-05 Chong Yidong <cyd@gnu.org>
2620 * process.c (wait_reading_process_output): Revert previous change.
2622 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2624 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2625 This removes code that has been obsolete since around 1990.
2626 * callproc.c (Fcall_process):
2628 * process.c (create_process):
2629 * term.c (dissociate_if_controlling_tty):
2630 Assume setsid exists.
2631 * callproc.c (child_setup): Assume setpgid exists and behaves as
2632 per POSIX.1-1988 or later.
2633 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2634 * emacs.c (shut_down_emacs):
2635 * sysdep.c (sys_suspend, init_foreground_group):
2636 Assume getpgrp behaves as per POSIX.1-1998 or later.
2637 * msdos.c (setpgrp): Remove.
2638 (tcgetpgrp, setpgid, setsid): New functions.
2639 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2640 * term.c (no_controlling_tty): Remove; unused.
2641 * w32proc.c (setpgrp): Remove.
2642 (setsid, tcgetpgrp): New functions.
2644 Simplify by assuming __fpending.
2645 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2646 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2647 Do not assume that __fpending's result fits in int.
2649 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2651 Remove EMACS_OUTQSIZE+sleep hack.
2652 * dispnew.c (update_frame_1): Remove hack for terminals slower
2653 than 2400 bps, which throttled Emacs by having it sleep.
2654 This code hasn't worked since at least 2007, when the multi-tty stuff
2655 was added, and anyway those old terminals are long dead.
2656 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2657 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2659 Fix data-loss with --version (Bug#9574).
2660 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2661 as we can't assume that emacs_strerror is initialized, and strerror
2662 is good enough here.
2663 (main): Invoke atexit earlier, to catch earlier instances of
2664 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2666 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2668 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2669 (keyDown): Remap keypad keys to X11 virtual key codes.
2671 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2673 Fix data-loss with --batch (Bug#9574).
2674 * emacs.c: Include <close-stream.h>.
2675 (close_output_streams): New function.
2676 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2677 and handles errors appropriately.
2678 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2681 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2682 The symptom is a diagnostic "GLib-WARNING **: In call to
2683 g_spawn_sync(), exit status of a child process was requested but
2684 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2685 waitpid(), so exit status can't be returned." The diagnostic
2686 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2687 The real bug is a race condition between Emacs and glib: Emacs
2688 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2689 so that glib can't find it. Work around the bug by invoking
2690 waitpid only on subprocesses that Emacs itself creates.
2691 * process.c (create_process, record_child_status_change):
2692 Don't use special value -1 in pid field, as the caller now must
2693 know the pid rather than having the callee infer it.
2694 The inference was sometimes incorrect anyway, due to another race.
2695 (create_process): Set new 'alive' member if child is created.
2696 (process_status_retrieved): New function.
2697 (record_child_status_change): Use it.
2698 Accept negative 1st argument, which means to wait for the
2699 processes that Emacs already knows about. Move special-case code
2700 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2701 processes that have already been waited for, by testing and
2702 clearing new 'alive' member.
2703 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2704 now does this internally.
2705 (handle_child_signal): Let record_child_status_change do all
2706 the work, since we do not want to reap all exited child processes,
2707 only the child processes that Emacs itself created.
2708 * process.h (Lisp_Process): New boolean member 'alive'.
2710 Omit duplicate definitions no longer needed with gcc -g3.
2711 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2712 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2713 Define only as macros. There's no longer any need to also define
2714 these symbols as enums or as constants, since we now assume
2715 gcc -g3 when debugging.
2717 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2719 * lisp.mk: Adjust comments to the fact that term/internal is now
2720 loaded from loadup.el.
2722 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2723 (msdos_fatal_signal): New function.
2724 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2727 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2728 for GCC versions before 4.
2729 (emacs_raise): Define to call msdos_fatal_signal.
2731 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2732 iterator when starting in the middle of a display or overlay
2735 2012-11-03 Chong Yidong <cyd@gnu.org>
2737 * process.c (wait_reading_process_output): Clean up the last
2740 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2742 * process.c (wait_reading_process_output): Avoid a race condition
2743 with SIGIO delivery (Bug#11536).
2745 2012-11-03 Chong Yidong <cyd@gnu.org>
2747 * buffer.c (cursor_type): Untabify docstring.
2749 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2751 * frame.h (struct frame): Drop can_have_scroll_bars member
2752 which is meaningless for a long time. Adjust comments.
2753 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2754 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2756 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2758 * window.c (decode_next_window_args): Update window arg after
2759 calling decode_live_window and so fix crash reported at
2760 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2761 by Juanma Barranquero <lekktu@gmail.com>.
2762 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2763 * font.c (Ffont_at): Likewise.
2765 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2767 * widget.c (resize_cb): New function.
2768 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2769 (EmacsFrameResize): Check if all is up to date before changing frame
2772 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2774 Implement backtrace output for fatal errors on MS-Windows.
2775 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2776 (BACKTRACE_LIMIT_MAX): New macro.
2777 (w32_backtrace): New function.
2778 (emacs_abort): Use w32_backtrace when the user chooses not to
2779 attach a debugger. Update the text of the abort dialog.
2781 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2783 Window-related stuff cleanup here and there.
2784 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2785 Use decode_any_window.
2786 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2787 * xdisp.c (Fformat_mode_line): Likewise.
2788 * font.c (Ffont_at): Use decode_live_window.
2789 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2790 * window.c (decode_next_window_args): Likewise.
2791 (decode_any_window): Remove static.
2792 * window.h (decode_any_window): Add prototype.
2793 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2794 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2797 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2799 Remove pad from struct input_event.
2800 * termhooks.h (struct input_event): Remove padding field.
2802 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2803 member is never cons for a long time. Adjust comment.
2804 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2805 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2806 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2807 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2809 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2811 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2813 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2815 Fix crash when using Emacs as commit editor for git (Bug#12697).
2816 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2817 and it is configured in conf_post.h.
2818 (Fcall_process): Don't invoke both setsid and setpgid; the former
2819 is enough, if it exists.
2820 * callproc.c (Fcall_process, child_setup):
2821 * process.c (create_process): Use setpgid.
2822 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2824 * dispnew.c (init_display): Initialize the foreground group
2825 if we are running a tty display.
2826 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2827 * lisp.h (init_foreground_group): New decl.
2828 * sysdep.c (inherited_pgroup): New static var.
2829 (init_foreground_group, tcsetpgrp_without_stopping)
2830 (narrow_foreground_group, widen_foreground_group): New functions.
2831 (init_sys_modes): Narrow foreground group.
2832 (reset_sys_modes): Widen foreground group.
2834 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2836 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2838 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2840 * minibuf.c (read_minibuf): Restore current buffer since
2841 choose_minibuf_frame calling Fset_frame_selected_window may
2842 change it (Bug#12766).
2844 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2846 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2848 2012-10-30 Kenichi Handa <handa@gnu.org>
2850 * font.c (Ffont_at): If WINDOW is specified and it is not
2851 displaying the current buffer, signal an error.
2853 2012-10-29 Daniel Colascione <dancol@dancol.org>
2855 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2856 In preparation for fixing bug#12739, move these functions from
2859 * coding.h, coding.c: ... to here, and compile them only when
2860 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2861 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2863 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2865 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2866 (timer_loop, getitimer, setitimer): Use it instead of
2867 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2869 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2872 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2874 * nsterm.m (NO_APPDEFINED_DATA): New define.
2875 (last_appdefined_event_data): New variable
2876 (last_appdefined_event): Remove.
2877 (ns_select): Initialize t from last_appdefined_event_data instead
2878 of [last_appdefined_event data1].
2879 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2880 remove last_appdefined_event (Bug#12698).
2882 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2884 * frame.c (x_set_font): Catch internal error.
2886 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2888 Avoid overflow in w32 implementation of interval timers.
2889 When possible, for ITIMER_PROF count only times the main thread
2891 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2892 'volatile ULONGLONG' types. All the other data which was
2893 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2894 (GetThreadTimes_Proc): New typedef.
2895 (w32_get_timer_time): New function, returns a suitable time value
2897 (timer_loop): Enter critical section when accessing ULONGLONG
2898 values of the itimer_data struct, as these accesses are no longer
2899 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2900 Remove unused variable.
2901 (init_timers): Initialize s_pfn_Get_Thread_Times.
2902 (start_timer_thread): Don't assign itimer->caller_thread here.
2903 (getitimer): Assign itimer->caller_thread here.
2904 (setitimer): Always call getitimer to get the value of ticks_now.
2905 (sys_spawnve): Avoid compiler warning about format mismatch.
2907 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2909 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2910 mouse movement events if the menu bar is active. This avoids
2911 producing a busy "hour-glass" cursor by Windows if the mouse
2912 pointer is positioned over a tooltip shown for some menu item.
2914 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2916 Don't assume process IDs fit in int.
2917 * emacs.c (shut_down_emacs) [!DOS_NT]:
2918 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2919 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2920 Use pid_t, not int, to store process IDs, as 'int'
2921 is not wide enough on a few platforms (e.g., AIX and IRIX).
2923 2012-10-23 Kenichi Handa <handa@gnu.org>
2925 The following change is to make face-font-rescale-alist work
2926 correctly for non-ASCII fonts.
2928 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2929 (font_open_for_lface): Handle Vface_font_rescale_alist.
2931 2012-10-23 Chong Yidong <cyd@gnu.org>
2933 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2935 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2939 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2941 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2944 2012-10-21 Glenn Morris <rgm@gnu.org>
2946 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2948 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2950 Port to OpenBSD 5.1.
2951 * frame.c (Fmouse_position, Fmouse_pixel_position):
2952 * xdisp.c (produce_stretch_glyph):
2953 Declare local vars only when they're needed.
2954 This is clearer and avoids a warning on OpenBSD about unused vars.
2955 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2956 This is safer, and avoids OpenBSD warnings about unused vars.
2957 * keyboard.c (record_menu_key): Remove unnecessary decl.
2958 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2959 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2960 as our definition clashes with OpenBSD's.
2961 * xfaces.c (load_face_colors, check_lface_attrs)
2962 (get_lface_attributes_no_remap, get_lface_attributes)
2963 (lface_fully_specified_p, x_supports_face_attributes_p)
2964 (tty_supports_face_attributes_p, face_fontset, realize_face)
2965 (realize_x_face, realize_tty_face):
2966 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2967 merely Lisp_Object *. This is more informative and avoids
2968 a warning on OpenBSD about accessing beyond an object's size.
2970 2012-10-20 Chong Yidong <cyd@gnu.org>
2972 * lread.c (Fload): Doc fix (Bug#12592).

2998 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2999 (staticpro): If we run out of staticpro slots, die with an
3000 informative error instead of just calling emacs_abort.
3002 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3004 Fix two flaws reported by Dmitry Antipov.

3258 Use unsigned for counter where wraparound-on-overflow is desired,
3259 since unsigned is guaranteed to have that behavior and signed is not.
3260 (read_char): Use ptrdiff_t for string length.
3261 (get_input_pending): Remove first argument, since it was always
3262 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3263 and behave as if it had that value. Return new value of
3264 input_pending. All callers changed.
3265 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3266 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3268 * keymap.c (push_key_description): Omit last arg, which was always 1.
3269 All callers changed.
3271 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
3273 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

3276 ($(BLD)/term.$(O)): Update dependencies.
3278 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3280 * alloc.c (mark_object): Use meaningful PVEC_NORMAL_VECTOR.
3281 * lisp.h (enum pvec_type): Adjust comments and omit explicit
3282 initializer for PVEC_NORMAL_VECTOR.
3284 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3286 Clean out old termopts cruft.
3287 * termopts.h (flow_control, meta_key): Remove unused decls.
3288 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
3289 Don't include termopts.h.
3291 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3293 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3295 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3297 * commands.h (immediate_quit): Remove duplicate decl.
3299 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3301 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
3303 (nsfont_open): Remove setting of Vfonts_in_cache.
3304 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3306 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3308 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3309 match what GetLastError returns. Explain why the function is
3312 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3313 'is_tooltip_frame', to avoid confusion with its global namesake.
3315 2012-10-08 Daniel Colascione <dancol@dancol.org>
3317 * xdisp.c (start_hourglass): Call w32_note_current_window when
3318 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3319 build that caused Emacs to display the hourglass cursor forever.
3321 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3322 which is broken under remote desktop, calculate the number of
3323 colors available for a display based on the display's number of
3324 planes and number of bits per pixel per plane. (bug#10397).
3326 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3328 * nsfont.m (Vfonts_in_cache): New variable.
3329 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3330 are used. Add cached fonts to Vfonts_in_cache.
3331 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3333 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3335 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3337 (FONT_H): Define after FRAME_H.
3338 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3339 Update dependencies.
3341 * w32term.c: Remove leftover declaration of keyboard_codepage.
3343 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3345 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3346 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3347 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3348 (GLOBAL_SOURCES): Add cygw32.c.
3349 ($(BLD)/unexw32.$(O)):
3351 ($(BLD)/w32console.$(O)):
3352 ($(BLD)/w32fns.$(O)):
3353 ($(BLD)/w32heap.$(O)):
3354 ($(BLD)/w32menu.$(O)):
3355 ($(BLD)/w32proc.$(O)): Add w32common.h.
3357 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3359 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3361 2012-10-08 Daniel Colascione <dancol@dancol.org>
3363 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3364 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3365 accidental message numbering hole. Change other messages to
3368 * w32select.h (HAVE_W32SELECT): Remove.
3370 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3371 w32common.h instead of w32heap.h.
3373 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3374 (get_allocation_unit, get_processor_type, get_w32_major_version)
3375 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3376 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3377 (OS_NT, os_subtype, cache_system_info): Move declarations to
3380 * w32heap.c: Include w32common.h.
3381 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3382 (w32_minor_version, w32_build_number, w32_subtype):
3383 Remove duplicate definitions.
3385 * w32fns.c: Include w32common.h; include w32heap.h only in
3388 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3389 Use `report_file_error' instead of `error' in order to better
3390 inform users of what went wrong. Increase NTGUI_UNICODE file
3391 dialog box file name length to 32k, the maximum allowed by the NT
3394 * w32common.h: New file.
3395 (ROUND_UP, ROUND_DOWN, get_page_size)
3396 (get_allocation_unit, get_processor_type, get_w32_major_version)
3397 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3398 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3399 (OS_NT, os_subtype, cache_system_info): Move here.
3401 * unexw32.c, unexcw.c: Include w32common.h.
3403 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3404 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3405 to call syms_of_w32select.
3407 * cygw32.h: Remove obsolete EXFUN declarations.
3409 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3411 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3412 of w32inevt.o from SOME_MACHINE_OBJECTS.
3414 2012-10-08 Daniel Colascione <dancol@dancol.org>
3416 * image.c: Permanent fix for JPEG compilation issue --- limit
3417 jpeglib `boolean' redefinition to Cygwin builds.
3419 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3421 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3423 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3426 2012-10-08 Daniel Colascione <dancol@dancol.org>
3428 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3429 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3430 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3431 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3432 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3433 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3434 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3435 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3436 now a supported configuration.
3438 * Makefile.in: consolidate image variables into LIBIMAGE; add
3439 W32_OBJ and W32_LIBS. Compile new files.
3442 (_DebPrint) declare tracing facility for W32 debugging. We need
3443 to unify tracing later.
3445 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3446 unconditional use of W32 Unicode functions. Cygwin runs only on
3447 100% Unicode operating systems.
3449 * cygw32.c: New file. Define Cygwin-specific facilities.
3450 (Fcygwin_convert_path_to_windows)
3451 (Fcygwin_convert_path_from_windows): New user functions for
3452 accessing Cygwin path-munging routines.
3454 * cygw32.h: New file.
3455 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3456 UTF-16LE strings temporarily inside non-Lisp-visible string
3459 (w32_strerror): Just what it says on the tin.
3461 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3462 also run for Cygwin; both systems have the same problem with using
3463 GUI facilities in a forked child. Also call syms_of_cygw32,
3464 syms_of_w32select in correct places.
3466 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3467 needs fork-then-exec for daemon launching.
3469 * font.h: Include frame.h.
3471 * image.c: Use the image library cache machinery only when we're
3472 compiling for native WINDOWSNT; Cygwin can use shared libraries
3473 like any other Unixlike system.
3475 * keyboard.c: Clarify a comment regarding the input loop.
3477 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3478 functions directly instead of trying to detect at runtime that our
3479 host operating system supports them. We make this change for two
3480 reasons: Cygwin lacks support for the multibyte character
3481 conversion functions used by the legacy menu code, and Cygwin
3482 never needs to rely on non-Unicode APIs.
3484 * unexw32.c (hinst): Declare extern.
3486 * w32.c: Change header order;
3487 (w32_strerror): Move to w32fns.c because we need it for
3488 non-WINDOWSNT builds.
3490 * w32.h: Add #error macro to make sure we don't include w32.h for
3491 Cygwin builds. Remove w32select declarations.
3493 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3494 w32fns.c. w32console.c is WINDOWSNT-only.
3496 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3497 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3499 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3500 (w32_major_version, w32_minor_version, w32_build_number)
3501 (os_subtype, sound_type): Define here
3502 (w32_defined_color): Make color parameter const for consistency
3503 with other _defined_color functions.
3504 (w32_createwindow): Unconditionally call w32_init_class instead of
3505 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3506 through the code is complex and unnecessary because class
3507 registration is practically free.
3508 (w32_name_of_message): New EMACSDEBUG-only function.
3509 (Fset_message_beep): Move here
3510 (Fx_open_connection): Require that the display name for Windows be
3511 "w32" for consistency, emacsclient disambiguation, and maybe, one
3512 day, multi-window-system support.
3513 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3514 Cygwin files for W32 GUI facilities, since these clearly don't
3515 expect Cygwin names.
3516 (_DebPrint): Define.
3517 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3518 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3519 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3520 (w32_last_error): Remove.
3522 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3524 * w32heap.c (syspage_mask): Declare here.
3525 (cache_system_info): Remove.
3527 * w32inevt.c (faked_key): Define globally, not statically.
3528 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3529 (w32_console_toggle_lock_key): Move to w32fns.c.
3531 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3533 * w32proc.c (_DebPrint): Move to w32fns.c.
3534 * w32select.c: Include string.h, stdio.h for Cygwin.
3535 * w32select.h: New File.
3537 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3539 (w32_message_fd): New variable. Under Cygwin, holds the file
3540 descriptor the system used to tell us about pending thread
3543 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3544 that prevented compilation under non-WINDOWSNT systems.
3546 (w32_initialize): Open /dev/windows and assign it to
3547 w32_message_fd. Provide w32 feature.
3549 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3550 (WM_EMACS_INPUT_READY): add.
3551 (prepend_msg, w32_message_fd): Declare globally.
3554 (keyboard_handle): Use only when WINDOWSNT.
3555 (notify_msg_ready): New function. Posts a message to the main
3556 thread's message queue under CYGWIN, which wakes up the main
3557 thread from select(2) by making the /dev/windows file descriptor
3558 ready. Under WINDOWSNT, it sets an event the same way the old
3561 (post, prepend_msg): Actually call notify_msg_ready instead of
3562 setting the input event directly.
3564 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3566 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3567 but it still has blocs in it, don't return it to the system,
3568 instead of aborting. (Bug#12402)
3570 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3572 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3574 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3575 MAC_OS_X_VERSION_10_6.
3576 (syms_of_nsterm): Remove comment about Panther and above for
3578 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3579 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3580 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3582 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3583 MAC_OS_X_VERSION_10_4.
3585 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3586 MAC_OS_X_VERSION_10_2.
3588 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3590 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3591 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3593 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3594 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3595 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3596 Remove ns_in_resize check.
3597 (ns_clear_frame_area): Remove resize handle code.
3599 * nsfns.m (ns_in_resize): Remove.
3600 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3601 Remove ns_in_resize check.
3603 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3605 Improve sys_siglist detection.
3606 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3607 defined as a macro, as is done in Solaris.
3608 (sys_siglist_entries): New macro.
3609 (save_strsignal): Use it.
3610 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3611 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3613 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3615 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3616 fullscreen/Fullscreen.
3618 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3619 tobar_height is new.
3621 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3622 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3623 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3624 (windowDidResize:): Check for correct window if old style fullscreen.
3625 Capitalize word in comment. Remove incorrect comment.
3626 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3627 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3628 error in drawing background.
3629 (toggleFullScreen:): Remove comment. Rearrange calls.
3630 Set toolbar values to zero, save old height in tobar_height.
3631 Restore tool bar height when leaving fullscreen.
3632 (canBecomeMainWindow): New function.
3634 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3636 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3638 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3640 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3642 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3643 that time stamps of directories could also be changed.
3644 Don't request the too broad GENERIC_WRITE, only the more restrictive
3645 FILE_WRITE_ATTRIBUTES access rights.
3647 * fileio.c (Fset_file_times): Special-case ignoring errors for
3648 directories only on MSDOS, not on MS-Windows.
3650 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3652 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3654 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3656 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3657 see whether CreateFile failed.
3659 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3661 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3662 to avoid similar races.
3663 * keyboard.c (pending_signals): Now bool, not int.
3665 Port timers to OpenBSD, plus check for timer failures.
3666 OpenBSD problem reported by Han Boetes.
3667 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3669 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3670 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3671 like OpenBSD, which has timer_settime but does not declare it.
3672 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3673 whether to use itimerspec-related primitives. All uses of
3674 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3676 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3678 * profiler.c (handle_profiler_signal): Fix a malloc race
3679 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3681 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3683 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3685 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3687 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3688 consistent with the change in return value of 'safe_strsignal'.
3690 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3692 Prefer plain 'static' to 'static inline' (Bug#12541).
3693 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3694 (bidi_set_sor_type, bidi_push_embedding_level)
3695 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3696 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3697 (bidi_cache_search, bidi_cache_ensure_space)
3698 (bidi_cache_iterator_state, bidi_cache_find)
3699 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3700 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3701 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3702 Now 'static', not 'static inline'.
3704 Count overruns when profiling; change units to ns.
3705 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3706 Give extra weight to samples after overruns, to attempt to count
3707 the time more accurately.
3708 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3709 the underlying primitives nominally do ns.
3710 (Fprofiler_cpu_start): Document the change. Mention that
3711 the sampling intervals are only approximate.
3713 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3715 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3717 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3718 case for the special 0 coding-system.
3720 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3721 (Fmake_overlay): Remove redundant tests.
3722 (fix_start_end_in_overlays): Remove redundant recentering.
3724 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3726 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3727 Update dependencies.
3729 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3731 Fix a malloc race condition involving strsignal.
3732 A signal can arrive in the middle of a malloc, and Emacs's signal
3733 handler can invoke strsignal, which can invoke malloc, which is
3734 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3735 Fix it by altering the signal handler so that it does not invoke
3737 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3738 * process.c (status_message): Use const pointer, in case strsignal
3739 is #defined to safe_strsignal.
3740 * sysdep.c (sys_siglist, init_signals): Always define and
3741 initialize a substitute sys_siglist if the system does not define
3742 one, even if HAVE_STRSIGNAL.
3743 (safe_strsignal): Rename from strsignal. Always define,
3744 using sys_siglist. Return a const pointer.
3745 * syssignal.h (safe_strsignal): New decl.
3746 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3748 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3750 * w32proc.c (timer_loop): Fix code that waits for timer
3751 expiration, to avoid high CPU usage.
3753 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3755 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3756 (sweep_weak_table): Remove redundant prototypes.
3758 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3760 * emacs.c: Move the inclusion of TERM_HEADER after including
3761 windows.h on WINDOWSNT. This avoids compilation problems with
3764 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3766 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3767 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3768 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3769 as the previous version used 'void *'.
3771 * ralloc.c (ROUNDUP): Fix last change.
3772 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3775 * w32proc.c <disable_itimers>: New static flag.
3776 (init_timers): Initialize it to zero, after creating the critical
3777 sections used by the timer threads.
3778 (term_timers): Set to 1 before deleting the critical sections.
3779 (getitimer, setitimer): If disable_itimers is non-zero, return an
3780 error indication without doing anything. Reported by Fabrice
3781 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3782 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3784 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3787 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3788 term_ntproc after all the other bookkeeping, to get timers working
3789 as long as possible.
3791 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3793 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3794 Suggested by Juri Linkov in
3795 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3797 Prefer plain 'static' to 'static inline' (Bug#12541).
3798 With static functions, modern compilers inline pretty well by
3799 themselves; advice from programmers often hurts as much as it helps.
3800 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3801 this change shrinks the text size of the Emacs executable by 1.1%
3802 without affecting CPU significantly in my benchmark.

3885 Revert the FOLLOW-SYMLINKS change for file-attributes.

3887 not enough time to get that tested before the freeze today.
3888 * dired.c (directory_files_internal, Ffile_attributes):

3928 compatibility with x64.
3930 * vm-limit.c (lim_data): Now size_t.
3931 (check_memory_limits): Adjust prototypes of real_morecore and
3932 __morecore to receive argument of type ptrdiff_t. Use size_t for

4086 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4087 signal.h, setjmp.h. Include systime.h instead.

4096 (handle_profiler_signal): Rename from sigprof_handler_1,
4097 for consistency with other handlers. Do not check whether
4098 cpu_log is a hash-table if garbage collecting, since it
4099 doesn't matter in that case.

4101 for consistency with other handlers.
4102 (setup_cpu_timer): New function, with much of what used to be in
4103 Fprofiler_cpu_start. Check for out-of-range argument.
4104 Prefer timer_settime if available, and prefer
4105 thread cputime clocks, then process cputime clocks, then
4106 monotonic clocks, to the old realtime clock. Use make_timeval
4107 to round more-correctly when falling back to setitimer.
4108 (Fprofiler_cpu_start): Use it.
4109 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4110 Don't assume that passing NULL as the 2nd argument of setitimer
4111 is the same as passing a pointer to all-zero storage.
4112 Ignore SIGPROF afterwards.
4113 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4114 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4115 non-fatal signal handlers. Ignore SIGPROF on startup.
4116 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4117 in profiler.c, since sysdep.c now uses it.
4119 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4175 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4176 Since this stuff is now private to charset.c, there's no need for
4177 a public macro and no need to inline by hand.

4208 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4210 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4212 Prefer POSIX timers if available.
4213 They avoid a race if the timer is too close to the current time.
4214 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4215 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4216 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4218 2012-09-25 Eli Zaretskii <eliz@gnu.org>

4223 STRING_CHAR_ADVANCE.
4225 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4227 Move Vlibrary_cache to emacs.c and reset before dumping.
4229 * lisp.h (reset_image_types): Declare.
4230 [WINDOWSNT] (Vlibrary_cache): Declare.
4232 * image.c (reset_image_types): New function.
4234 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

4241 * w32.h (Vlibrary_cache): Do not declare.
4243 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4245 * w32proc.c (sys_signal): Handle all signals defined by the
4246 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4247 handlers for signals supported by Windows. Don't override
4248 term_ntproc as the handler for SIGABRT.
4249 (sigaction): Rewrite to call sys_signal instead of duplicating its
4251 (sys_kill): Improve commentary.
4253 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4254 consistency with a signature of a signal handler. All callers
4256 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4257 install term_ntproc as a signal handler for SIGABRT, as that
4258 should be done by the dumped Emacs.
4260 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4262 * w32select.c (term_w32select): Protect against repeated
4263 invocation by setting clipboard_owner to NULL after calling

4274 2012-09-25 Chong Yidong <cyd@gnu.org>
4276 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4278 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4280 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4281 when encountering an unknown bytecode.
4283 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4285 image.c, indent.c: Use bool for booleans.
4286 * dispextern.h (struct image_type): Members valid_p, load, init
4287 now return bool, not int. All uses changed.
4288 * image.c: Omit unnecessary static decls.
4289 (x_create_bitmap_mask, x_build_heuristic_mask):
4290 Return void, not int, since callers don't care about the return value.

4319 Use bool for booleans.
4321 2012-09-24 Chong Yidong <cyd@gnu.org>
4323 * chartab.c (Fset_char_table_default): Obsolete function removed.
4325 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4327 Move pid_t related decls out of lisp.h.
4328 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4329 (interruptible_wait_for_termination):
4330 Move these decls from lisp.h to syswait.h, since they use pid_t.
4331 Needed on FreeBSD; see Herbert J. Skuhra in
4332 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4333 * callproc.c: Include syswait.h.

4350 * nsmenu.m (ns_update_menubar):
4351 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4352 * xfns.c (Fx_show_tip) [USE_GTK]:
4353 Use bool for boolean.
4354 * gtkutil.c (xg_update_frame_menubar):
4355 * xmenu.c (update_frame_menubar):
4356 Return void, not int, since caller ignores return value.
4357 * gtkutil.c (xg_change_toolbar_position):
4360 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4362 * makefile.w32-in (BLOCKINPUT_H): Remove.

4379 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4381 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4382 fatal_error_backtrace.
4384 * w32proc.c (sys_kill): Undo last change: don't do anything when
4385 invoked to deliver SIGABRT to our own process. This is now
4386 handled by emacs_raise.
4388 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4390 * w32term.c (w32_read_socket): Remove leftover reference to
4391 interrupt_input_pending.
4393 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4395 Do not use SA_NODEFER.
4396 Problem reported by Dani Moncayo in
4397 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4399 * sysdep.c (emacs_abort): Do not reset signal handler.
4400 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4401 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4402 wanted even on POSIXish hosts, and it doesn't work on Windows.
4404 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4406 * xterm.c (x_term_init): Call fixup_locale before and after calling
4407 gtk_init (Bug#12392).
4409 2012-09-23 Chong Yidong <cyd@gnu.org>
4411 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4412 Vdynamic_library_alist.
4414 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4415 (Fgnutls_available_p): Caller changed.
4417 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4418 (Flibxml_parse_xml_region): Likewise.
4420 * dispextern.h (struct image_type): Remove arg from init function.
4422 * image.c (Finit_image_library, lookup_image_type)
4423 (define_image_type): Remove now-unneeded second arg.
4424 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4425 (init_tiff_functions, init_gif_functions, init_svg_functions):
4426 Arglist and w32_delayed_load calling convention changed.
4427 (gs_type): Remove init_gs_functions; there is no such function.
4428 (valid_image_p, make_image): Fix caller to lookup_image_type.
4430 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4432 Simplify and avoid signal-handling races (Bug#12471).
4434 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4435 Avoid recursive loop if there's a fatal error in the function itself.
4436 * atimer.c (pending_atimers):
4437 * blockinput.h: Don't include "atimer.h"; no longer needed.
4438 (interrupt_input_pending): Remove. All uses removed.
4439 pending_signals now counts both atimers and ordinary interrupts.
4440 This is less racy than having three separate pending-signal flags.
4441 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4443 Rename from their upper-case counterparts BLOCK_INPUT,
4444 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4445 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4446 This makes it easier to access volatile variables more accurately.
4447 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4448 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4449 that's more reliable if the code is buggy and sets
4450 interrupt_input_blocked to a negative value. All uses changed.
4451 * atimer.c (deliver_alarm_signal):
4452 Remove. No need to deliver this to the parent; any thread can
4453 handle this signal now. All uses replaced by underlying handler.
4454 * atimer.c (turn_on_atimers):
4455 * dispnew.c (handle_window_change_signal):
4456 * emacs.c (handle_danger_signal):
4457 * keyboard.c (kbd_buffer_get_event):
4458 Don't reestablish signal handler; not needed with sigaction.
4459 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4461 Rework to avoid unnecessary accesses to volatile variables.
4462 (UNBLOCK_INPUT_TO): Now a function.
4463 (totally_unblock_input, unblock_input): New decls.
4464 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4465 (init_data): Remove. Necessary stuff now done in init_signal.
4466 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4467 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4468 (fatal_error_code): Remove; no longer needed.
4469 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4470 it doesn't always backtrace. All uses changed. No need to reset
4471 signal to default, since sigaction and/or die does that for us now.
4472 Use emacs_raise (FOO), not kill (getpid (), FOO).
4473 (main): Check more-accurately whether we're dumping.
4474 Move fatal-error setup to sysdep.c
4475 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4476 * gtkutil.c (xg_get_file_name, xg_get_font):
4477 Remove no-longer-needed signal-mask manipulation.
4478 * keyboard.c, process.c (POLL_FOR_INPUT):
4479 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4480 * keyboard.c (read_avail_input): Remove.
4481 All uses replaced by gobble_input.
4482 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4483 (kbd_buffer_store_event_hold, gobble_input):
4484 (record_asynch_buffer_change) [USABLE_SIGIO]:
4485 (store_user_signal_events):
4486 No need to mess with signal mask.
4487 (gobble_input): If blocking input and there are terminals, simply
4488 set pending_signals to 1 and return. All hooks changed to not
4489 worry about whether input is blocked.
4490 (process_pending_signals): Clear pending_signals before processing
4491 them, in case a signal comes in while we're processing.
4492 By convention callers now test pending_signals before calling us.
4493 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4494 New functions, to support changes to blockinput.h.
4495 (handle_input_available_signal): Now extern.
4496 (reinvoke_input_signal): Remove. All uses replaced by
4498 (quit_count): Now volatile, since a signal handler uses it.
4499 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4500 All callers changed. Block SIGINT only if not already blocked.
4501 Clear sigmask reliably, even if Fsignal returns, which it can.
4502 Omit unnecessary accesses to volatile var.
4503 (quit_throw_to_read_char): No need to restore sigmask.
4504 * keyboard.c (gobble_input, handle_user_signal):
4505 * process.c (wait_reading_process_output):
4506 Call signal-handling code rather than killing ourselves.
4507 * lisp.h: Include <float.h>, for...
4508 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4509 (pending_signals): Now volatile.
4510 (syms_of_data): Now const if IEEE floating point.
4511 (handle_input_available_signal) [USABLE_SIGIO]:
4512 (terminate_due_to_signal, record_child_status_change): New decls.
4513 * process.c (create_process): Avoid disaster if memory is exhausted
4514 while we're processing a vfork, by tightening the critical section
4516 (send_process_frame, process_sent_to, handle_pipe_signal)
4517 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4519 (send_process): No need for setjmp/longjmp any more, since the
4520 SIGPIPE stuff is now gone. Instead, report an error if errno
4522 (record_child_status_change): Now extern. PID and W are now args.
4523 Return void, not bool. All callers changed.
4524 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4525 Remove. All uses removed. This bug should be fixed now in a
4527 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4528 and record the child status change directly. This avoids the
4529 need to futz with the signal mask.
4530 (process_fatal_action): Move here from emacs.c.
4531 (emacs_sigaction_flags): New function, containing
4532 much of what used to be in emacs_sigaction_init.
4533 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4534 caught by emacs, to make races less likely.
4535 (deliver_process_signal): Rename from handle_on_main_thread.
4537 (BACKTRACE_LIMIT_MAX): Now at top level.
4538 (thread_backtrace_buffer, threadback_backtrace_pointers):
4540 (deliver_thread_signal, deliver_fatal_thread_signal):
4541 New functions, for more-accurate delivery of thread-specific signals.
4542 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4543 (deliver_arith_signal): Handle in this thread, not
4544 in the main thread, since it's triggered by this thread.
4545 (maybe_fatal_sig): New function.
4546 (init_signals): New arg DUMPING so that we can be more accurate
4547 about whether we're dumping. Caller changed.
4548 Treat thread-specific signals differently from process-general signals.
4549 Block all signals while handling fatal error; that's safer.
4550 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4552 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4553 Ignore SIGPIPE unless batch.
4554 (emacs_backtrace): Output backtrace for the appropriate thread,
4555 which is not necessarily the main thread.
4556 * syssignal.h: Include <stdbool.h>.
4557 (emacs_raise): New macro.
4558 * xterm.c (x_connection_signal): Remove; no longer needed
4559 now that we use sigaction.
4560 (x_connection_closed): No need to mess with sigmask now.
4561 (x_initialize): No need to reset SIGPIPE handler here, since
4562 init_signals does this for us now.
4564 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4566 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4567 background rect may be larger (Bug#12245).
4569 2012-09-23 Chong Yidong <cyd@gnu.org>
4571 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4573 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4575 * .gdbinit: Just stop at fatal_error_backtrace.
4576 See Stefan Monnier's request in
4577 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4578 Remove no-longer-used query of system type.
4580 2012-09-22 Chong Yidong <cyd@gnu.org>
4582 * search.c (Freplace_match): Doc fix (Bug#12325).
4584 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4586 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4587 (Fline_end_position): Doc fix.
4589 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4591 2012-09-22 Chong Yidong <cyd@gnu.org>
4593 * dispextern.h (struct image_type): Add new slot, storing a type
4594 initialization function.
4596 * image.c (define_image_type): Call the image initializer function
4597 if it is defined. Arguments and return value changed.
4598 (valid_image_p, make_image): Callers changed.
4599 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4600 (gif_type, imagemagick_type, svg_type, gs_type):
4601 Add initialization functions.
4602 (Finit_image_library): Call lookup_image_type.
4603 (CHECK_LIB_AVAILABLE): Macro deleted.
4604 (lookup_image_type): Call define_image_type here, rather than via
4605 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4606 (syms_of_image): Move define_image_type calls for xbm_type and
4607 pbm_type to lookup_image_type.
4609 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4611 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4612 'idle_timers' from here ...
4613 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4614 lists, to avoid infloops when the timer does something stupid,
4615 like reinvoke itself with the same or smaller time-out.
4618 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4620 * window.c (Fsplit_window_internal): Handle only Qt value of
4621 Vwindow_combination_limit separately.
4622 (Qtemp_buffer_resize): New symbol.
4623 (Vwindow_combination_limit): New default value.
4626 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4628 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4629 the new overlay string. (Bug#10159)
4631 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4633 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4634 or that fprintf is async-signal-safe. POSIX doesn't require
4637 2012-09-22 Chong Yidong <cyd@gnu.org>
4639 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4642 2012-09-22 Kenichi Handa <handa@gnu.org>
4644 * composite.c (composition_reseat_it): Handle the case that a
4645 grapheme cluster is not covered by a single font (Bug#12352).
4647 2012-09-21 Chong Yidong <cyd@gnu.org>
4649 * image.c (define_image_type): Avoid adding duplicate types to
4650 image_types (Bug#12463). Suggested by Jörg Walter.
4652 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4654 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4655 (print_load_command_name): Add case LC_DATA_IN_CODE.
4656 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4658 2012-09-21 Glenn Morris <rgm@gnu.org>
4660 * eval.c (Frun_hook_with_args_until_success)
4661 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4663 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4665 * fileio.c (Ffile_selinux_context): Only call freecon when
4666 lgetfilecon succeeded.
4667 (Fset_file_selinux_context): Likewise. (Bug#12444)
4669 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4671 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4672 reordering, locate the cursor by calling set_cursor_from_row; if
4673 that fails, clear the desired glyph matrix before returning a
4674 failure indication to the caller. Fixes leaving garbled display
4675 when fast scrolling with a down-key. (Bug#12403)
4676 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4677 scrolling through multibyte text.
4679 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4681 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4682 calling mark_vectorlike since that's the one that marks the window.
4683 (mark_discard_killed_buffers): Mark the final cdr.
4684 * window.h (struct window): Move prev/next_buffers to the
4685 non-standard fields.
4686 * window.c (make_window): Initialize prev/next_buffers manually.
4688 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4690 Omit unused arg EXPECTED from socket hooks.
4691 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4692 * nsterm.m (ns_term_init):
4693 * termhooks.h (struct terminal.read_socket_hook):
4694 * w32inevt.c (w32_console_read_socket):
4695 * w32term.c (w32_read_socket):
4696 * xterm.c (XTread_socket):
4697 Omit unused arg EXPECTED. All callers changed.
4698 (store_user_signal_events): Return void, not int, since callers no
4699 longer care about the return value. All uses changed.
4701 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4703 * w32gui.h (XParseGeometry): Do not declare.
4705 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4707 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4708 Ignore 'expected'. See Eli Zaretskii in
4709 <http://bugs.gnu.org/12471#8> (last line).
4711 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4712 (XParseGeometry): Now static. Substitute extremal values for
4713 values that are out of range.
4715 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4717 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4719 * nsfns.m (XParseGeometry): Remove.
4720 (Fx_create_frame): Call x_set_offset to correctly interpret
4721 top_pos in geometry.
4723 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4724 (Fx_parse_geometry): If there is a space in string, call
4725 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4727 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4729 * search.c (scan_buffer): Use character positions in calls to
4730 region_cache_forward and region_cache_backward, not byte
4731 positions. (Bug#12196)
4733 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4734 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4736 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4737 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4738 emacs_blocked_malloc, now deleted.
4740 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4742 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4743 The workaround was for improving performance on Solaris 2.4, but
4744 is getting in the way now. Emacs will still work if someone is
4745 still running Solaris 2.4 in a museum somewhere; Sun dropped
4746 support for Solaris 2.4 in 2003.
4747 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4748 * process.c (create_process) [HAVE_WORKING_VFORK]:
4749 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4750 since Emacs no longer uses vfork on that platform.
4752 2012-09-17 Glenn Morris <rgm@gnu.org>
4754 * emacs.c: Use COPYRIGHT.
4756 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4758 Remove configure's --without-sync-input option (Bug#12450).
4759 When auditing signal-handling in preparation for cleaning it up,
4760 I found that SYNC_INPUT has race conditions and would be a real
4761 pain to fix. Since it's an undocumented and deprecated
4762 configure-time option, now seems like a good time to remove it.
4763 Also see <http://bugs.gnu.org/11080#16>.
4764 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4765 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4766 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4767 (malloc_hysteresis):
4768 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4769 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4770 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4771 (dont_register_blocks, bytes_used_when_reconsidered)
4772 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4773 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4774 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4775 Remove. All uses removed.
4776 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4777 implementation, one that depends on whether the new macro
4778 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4780 * atimer.c (run_timers, handle_alarm_signal):
4781 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4782 (handle_async_input, process_pending_signals)
4783 (handle_input_available_signal, init_keyboard):
4784 * nsterm.m (ns_read_socket):
4785 * process.c (wait_reading_process_output):
4786 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4787 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4789 * xterm.c (XTread_socket):
4791 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4792 * eval.c (handling_signal): Remove. All uses removed.
4793 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4794 All uses replaced with the SYNC_INPUT version.
4795 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4797 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4800 * font.c (Ffont_shape_gstring): Remove unused local.
4802 2012-09-16 Glenn Morris <rgm@gnu.org>
4804 * Makefile.in (clean): No longer run nextstep's clean.
4806 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4808 (ns-app): Move here from ns.mk, and simplify.
4809 (clean): Simplify nextstep entry.
4810 * ns.mk: Remove file.
4812 2012-09-17 Kenichi Handa <handa@gnu.org>
4814 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4815 not covert the last few charactes.
4817 2012-09-16 Kenichi Handa <handa@gnu.org>
4819 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4820 here, but just check the validity of glyphs in the glyph-string.
4822 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4824 * window.c (Fwindow_parameter, Fset_window_parameter):
4825 Accept any window as argument (Bug#12452).
4827 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4829 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4830 to ns_term_init to avoid memory leak.
4832 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4833 explicit retain/release.
4834 (ns_term_init): Only allow one display. Initialize outerpool and
4837 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4839 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4840 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4841 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4842 the Microsoft problem in a different way, by altering ../nt/config.nt.
4844 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4859 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4860 by lisp.h. This completes removal of setjmp.h inclusion
4861 erroneously announced in the previous commit. (Bug#12446)
4863 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4866 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4867 not defined as a macro. The latter happens on MS-Windows.
4870 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4872 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4873 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4874 Some instances of '#include <setjmp.h>' removed, if the
4875 only reason for the instance was because "lisp.h" was included.
4876 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4877 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4878 and _longjmp with the new symbols. Emacs already uses _setjmp if
4879 available, so this change affects only POSIXish hosts that have
4880 sigsetjmp but not _setjmp, such as some versions of Solaris and
4881 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4882 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4883 (png_load_body) [HAVE_PNG]:
4884 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4885 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4886 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4887 since PNG requires jmp_buf. This is the only exception to the
4888 general rule that we now use sys_setjmp and sys_longjmp.
4889 This exception is OK since this code does not change the signal
4890 mask or longjmp out of a signal handler.
4892 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4894 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4895 Include "syssignal.h", for 'main_thread'.
4897 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4899 Avoid out-of-range marker position (Bug#12426).
4900 * insdel.c (replace_range, replace_range_2):
4901 Adjust markers before overlays, as suggested by comments.
4902 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4903 Remove redundant check before calling offset_intervals.
4905 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4907 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4908 current buffer (Bug#12387).
4910 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4912 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4914 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4916 Use a more backwards-compatible timer format (Bug#12430).
4917 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4918 vector element, not from the 4th, since PSECS is now at the end.
4919 (Fcurrent_idle_time): Doc fix.
4921 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4923 Function to mark objects and remove killed buffers at once.
4924 * alloc.c (discard_killed_buffers): Rename to ...
4925 (mark_discard_killed buffers) ... new name. Add marking
4926 of remaining objects. Fix comment. Adjust users.
4927 (mark_object): Do not touch frame buffer lists here.
4928 * frame.c (delete_frame): Reset frame buffer lists here.
4930 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4932 Better workaround for GNOME bug when --enable-gcc-warnings.
4933 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4934 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4935 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4937 Simplify SIGIO usage (Bug#12408).
4938 The code that dealt with SIGIO was crufty and confusing, e.g., it
4939 played tricks like "#undef SIGIO" but these tricks were not used
4940 consistently. Simplify mostly by not #undeffing standard symbols,
4941 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4942 or not as we please) rather than "defined SIGIO" (standard symbol
4943 that we probably shouldn't #undef).
4944 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4945 Modules that need it can include it.
4946 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4947 * dispextern.h (ignore_sigio): New decl.
4948 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4949 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4950 * emacs.c (shut_down_emacs):
4951 * keyboard.c (kbd_buffer_store_event_hold):
4952 Use ignore_sigio rather than invoking 'signal' directly.
4953 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4955 (FIONREAD, SIGIO): Do not #undef.
4956 (tty_read_avail_input): Use #error rather than a syntax error.
4957 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4958 for I_PIPE, used by SETUP_SLAVE_PTY.
4959 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4960 * sysdep.c (croak): Remove; no longer needed. This bit of
4961 temporary code, with Fred N. Fish's comment that it's temporary,
4962 has been in Emacs since at least 1992!
4963 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4964 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4965 * syssignal.h (croak): Remove decl.
4966 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4967 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4968 now that we're termios-only.
4969 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4970 * term.c (dissociate_if_controlling_tty): Use #error rather than
4973 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4974 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4975 to work around GNOME bug 683906.
4976 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4977 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4978 This works around GCC bug 54561.
4980 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4982 More fixes for 'volatile' and setjmp/longjmp.
4983 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4984 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4985 (png_load_body) [HAVE_PNG]:
4986 (jpeg_load_body) [HAVE_JPEG]:
4987 New function, with most of the old parent function's body.
4988 (png_load) [HAVE_PNG]:
4989 (jpeg_load) [HAVE_JPEG]:
4990 Invoke the new function, to avoid longjmp munging our locals.
4991 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4992 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4993 longjmp is passed 2, as the C standard doesn't guarantee this.
4994 Instead, store the failure code into mgr->failure_code.
4996 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4998 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4999 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5000 (syms_of_keyboard): Remove support for unread-command-char.
5002 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5004 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5005 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5006 violation. (Bug#12426)
5008 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5010 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5012 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5014 * eval.c: Add `inhibit-debugger'.
5015 (Qinhibit_debugger): New symbol.
5016 (call_debugger): Bind it instead of Qdebug_on_error.
5017 (maybe_call_debugger): Test Vinhibit_debugger.
5018 (syms_of_eval): Define inhibit-debugger.
5019 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5020 (syms_of_xdisp): Remove inhibit-debug-on-message.
5022 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5024 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5025 If a nonvolatile local variable is written before a _longjmp to
5026 the frame containing the variable, and is read after the _longjmp,
5027 the value read is indeterminate. Some local variables of type
5028 'struct handler' and 'struct catchtag' are used in this way, so
5029 mark each of their slots as volatile if the slot can be set before
5030 _longjmp and read afterwards.
5031 * lisp.h (struct handler): var and chosen_clause are now volatile.
5032 (struct catchtag): val, next, and pdlcount are now volatile.
5034 * bidi.c (bidi_push_it, bidi_pop_it):
5035 * fns.c (copy_hash_table):
5036 * image.c (define_image_type):
5037 * keyboard.c (kbd_buffer_store_event_hold):
5038 * process.c (Fprocess_send_eof):
5039 * xfaces.c (x_create_gc) [HAVE_NS]:
5040 * xgselect.c (xg_select):
5041 Prefer assignment to memcpy when either will do.
5043 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5044 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5045 time an item is removed. No need to mark this function 'inline';
5046 the compiler knows better than we do.
5048 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5050 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5051 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5052 to change_frame_size (Bug#12388).
5053 (windowDidResize:): Pass YES to updateFrameSize.
5055 * nsterm.h: Add delay parameter to updateFrameSize.
5057 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5059 Discard killed buffers from deleted window and frame objects.
5060 This reduces an amount of references to killed buffers and
5061 helps GC to reclaim them faster.
5062 * alloc.c (discard_killed_buffers): New function.
5063 (mark_object): Use it for deleted windows and frames.
5064 (mark_object): If symbol's value is set up for a killed buffer
5065 or deleted frame, restore its global binding.
5066 * data.c (swap_in_global_binding): Add GC notice.
5067 (swap_in_symval_forwarding): Use convenient set_blv_where.
5068 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5069 * window.h: ... to here.
5071 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5073 Convenient macro to check whether the buffer is live.
5074 * buffer.h (BUFFER_LIVE_P): New macro.
5075 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5076 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5078 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5080 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5081 composition cases (Bug#12364).
5083 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5084 overhang of succeeding glyphs overlapping box cursor.
5086 * w32term.c (x_draw_glyph_string): Likewise.
5088 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5090 Simplify, document, and port floating-point (Bug#12381).
5091 The porting part of this patch fixes bugs on non-IEEE platforms
5092 with frexp, ldexp, logb.
5093 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5095 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5096 support, by removing commented-out code and briefly listing the
5097 C89 functions excluded. The commented-out stuff was confusing
5098 maintenance, e.g., we thought we needed cbrt but it was commented out.
5099 (logb): Remove decl; no longer needed.
5100 (isfinite): New macro, if not already supplied.
5101 (isnan): Don't replace any existing macro.
5102 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5103 are present on all C89 platforms.
5104 (Ffrexp): Do not special-case zero, as frexp does the right thing
5106 (Flogb): Do not use logb, as it doesn't have the desired meaning
5107 on hosts that use non-base-2 floating point. Instead, stick with
5108 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5109 frexp, to avoid getting an unspecified result.
5111 * xdisp.c (Qinhibit_debug_on_message): Now static.
5113 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5115 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5116 NSBezierPath (Bug#12131).
5118 2012-09-10 Chong Yidong <cyd@gnu.org>
5120 * fns.c (Fdelq, Fdelete): Doc fix.
5122 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5124 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5125 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5127 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5129 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5130 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5133 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5135 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5136 left fringe if the window has a left margin. This avoids leaving
5137 traces of the cursor because its leftmost pixel is not drawn over.
5139 * dispnew.c (update_window_line): When the left margin area of a
5140 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5141 that screen line. (Bug#12277)
5143 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5145 Assume C89 or later for math functions (Bug#12381).
5146 This simplifies the code, and makes it a bit smaller and faster,
5147 and (most important) makes it easier to clean up signal handling
5148 since we can stop worring about floating-point exceptions in
5149 library code. That was a problem before C89, but the problem
5150 went away many years ago on all practical Emacs targets.
5151 * data.c, image.c, lread.c, print.c:
5152 Don't include <math.h>; no longer needed.
5153 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5154 might be autoconfigured, as that never happens.
5156 * doprnt.c (DBL_MAX_10_EXP):
5157 * print.c (DBL_DIG):
5158 Remove. C89 or later always defines these.
5159 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5160 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5161 (arith_error, domain_error, domain_error2):
5162 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5163 no longer needed -- we simply return what C returns. All uses removed.
5164 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5166 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5167 Remove. All uses expanded, as these macros are no longer used
5168 more than once and are now more trouble than they're worth.
5169 (Ftan): Use tan, not sin / cos.
5170 (Flogb): Assume C89 frexp.
5171 (fmod_float): Assume C89 fmod.
5172 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5173 (init_floatfns): Remove. All uses removed.
5175 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5177 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5178 compositeToPoint for OSX < 10.6 (Bug#12390).
5180 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5182 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5183 This produces more-accurate results.
5185 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5187 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5188 changes (Bug#12088).
5190 2012-09-08 Chong Yidong <cyd@gnu.org>
5192 * syntax.c (Fstring_to_syntax): Doc fix.
5194 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5196 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5197 in the internal border.
5198 (x_set_window_size): Remove static variables and their usage.
5199 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5200 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5201 Remove fringe/internal border adjustment (Bug#11052).
5202 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5203 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5204 (ns_fix_rect_ibw): Remove.
5205 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5206 (ns_dumpglyphs_box_or_relief): Ditto.
5207 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5209 (ns_dumpglyphs_image): Ditto.
5210 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5212 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5213 their usage. Add fringe_extended_p and its use as in other terms.
5214 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5215 scroll bar was removed.
5216 (updateFrameSize): New function.
5217 (windowDidResize): Move code to updateFrameSize and call it.
5219 * nsterm.h (EmacsView): Add updateFrameSize.
5221 2012-09-07 Chong Yidong <cyd@gnu.org>
5223 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5225 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5227 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5229 More signal-handler cleanup (Bug#12327).
5230 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5231 Problem introduced when merging patches. Noted by Eli Zaretskii in
5232 <http://bugs.gnu.org/12327#67>.
5233 * floatfns.c: Comment fix.
5234 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5235 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5236 and anyway the declaration is harmless even if SIGDANGER is not defined.
5237 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5238 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5239 source files not surprisingly expected syssignal.h to define, or
5240 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5241 Include <sys/ioctl.h>, for FIONREAD.
5242 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5243 This eliminates a problem whereby other files mysteriously had
5244 to include "syssignal.h" before including "systty.h" if they
5245 wanted to use "#ifdef SIGIO".
5247 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5249 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5251 * w32.c (sigemptyset): Empty the set.
5252 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5254 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5256 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5258 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5259 (mark_object): Likewise for frame objects.
5261 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5263 * syssignal.h (handle_on_main_thread): Always declare,
5264 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5265 This ports to platforms without HAVE_PTHREAD.
5267 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5269 Signal-handler cleanup (Bug#12327).
5270 Emacs's signal handlers were written in the old 4.2BSD style with
5271 sigblock and sigmask and so forth, and this led to some
5272 inefficiencies and confusion. Rewrite these to use
5273 pthread_sigmask etc. without copying signal sets around. Also,
5274 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5275 'signal', and instead use functions that do not attempt to take
5276 over the system name space. This patch causes Emacs's text
5277 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5278 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5279 Do not include <signal.h> or "syssignal.h", as these
5280 modules do not use signals.
5281 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5282 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5283 Do not include <signal.h>, as "syssignal.h" does that for us now.
5284 * atimer.c (sigmask_atimers): New function.
5285 (block_atimers, unblock_atimers): New functions,
5286 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5288 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5289 no longer needed here.
5290 * emacs.c (main): Inspect existing signal handler with sigaction,
5291 so that there's no need to block and unblock SIGHUP.
5292 * sysdep.c (struct save_signal): New member 'action', replacing
5293 old member 'handler'.
5294 (save_signal_handlers, restore_signal_handlers):
5295 Use sigaction instead of 'signal' to save and restore.
5296 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5297 New function. All users of 'signal' modified to use set_sighandler
5298 if they're writeonly, and to use sys_signal if they're read+write.
5299 (emacs_sigaction_init, forwarded_signal): New functions.
5300 (sys_signal): Remove. All uses replaced by calls to sigaction
5301 and emacs_sigaction_init, or by direct calls to 'signal'.
5302 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5303 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5304 all uses replaced by pthread_sigmask etc. calls.
5305 * syssignal.h: Include <signal.h>.
5306 (emacs_sigaction_init, forwarded_signal): New decls.
5307 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5308 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5309 (sigmask, sys_sigmask): Remove; no longer needed.
5310 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5311 (sigblock, sigunblock, sigfree):
5312 (sigsetmask) [!defined sigsetmask]:
5313 Remove. All uses replaced by pthread_sigmask.
5314 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5315 no longer need to be replaced, and its typical old uses
5316 are now done via emacs_sigaction_init and sigaction.
5317 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5318 (sys_sigdel): Remove; unused.
5319 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5321 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5323 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5324 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5326 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5328 Explicitly mark buffer_defaults and buffer_local_symbols.
5329 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5330 mark_local_symbols here.
5331 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5332 since special buffers aren't marked here any more.
5333 (allocate_buffer): Chain new buffer with all_buffers here...
5334 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5336 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5337 (syms_of_buffer): Remove staticpro of the above.
5338 (init_buffer_once): Set names for buffer_defaults and
5339 buffer_local_symbols.
5341 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5343 Use bool for booleans in font-related modules.
5344 * font.c (font_intern_prop, font_style_to_value)
5345 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5346 (generate_otf_features, font_check_otf_features, font_check_otf)
5347 (font_match_p, font_list_entities, font_at):

5349 (fontset_find_font, Fset_fontset_font)
5350 (face_suitable_for_char_p) [0]:
5351 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5352 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5353 (m17n_flt_initialized, ftfont_shape_by_flt):

5355 * nsfont.m (nsfont_draw):
5356 * w32font.c (w32font_draw):
5357 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5358 Use bool for booleans.
5359 * font.h: Adjust to above API changes.
5360 (struct font, struct font_driver, struct font_driver_list):
5361 Use bool for booleans.
5362 (struct font): Remove useless member encoding_type.
5364 * fontset.c, xftfont.c: Omit unnecessary static decls.
5366 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5368 * alloc.c (mark_object): Revert window marking code
5369 since it's unsafe for the Fset_window_configuration.
5371 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5373 Fix race conditions with signal handlers and errno (Bug#12327).
5374 Be more systematic about preserving errno whenever a signal
5375 handler returns, even if it's not in the main thread. Do this by
5376 renaming signal handlers to distinguish between signal delivery
5377 and signal handling. All uses changed.
5378 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5379 * data.c (deliver_arith_signal): Rename from arith_error.
5380 * dispnew.c (deliver_window_change_signal): Rename from
5381 window_change_signal.
5382 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5383 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5384 * keyboard.c (deliver_input_available_signal): Rename from
5385 input_available_signal.
5386 (deliver_user_signal): Rename from handle_user_signal.
5387 (deliver_interrupt_signal): Rename from interrupt_signal.
5388 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5389 (deliver_child_signal): Rename from sigchld_handler.
5390 * atimer.c (handle_alarm_signal):
5391 * data.c (handle_arith_signal):
5392 * dispnew.c (handle_window_change_signal):
5393 * emacs.c (handle_fatal_signal, handle_danger_signal):
5394 * keyboard.c (handle_input_available_signal):
5395 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5396 * process.c (handle_pipe_signal, handle_child_signal):
5397 New functions, with the actual signal-handling code taken from the
5398 original respective signal handlers, sans the sporadic attempts to
5399 preserve errno, since that's now done by handle_on_main_thread.
5400 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5401 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5402 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5404 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5405 Move initialization of main_thread to sysdep.c's init_signals.
5406 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5407 our usage, and simplifies the mainline code.
5408 (record_child_status_change): New static function, as a helper
5409 for handle_child_signal, and with most of the old child handler's
5411 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5412 (handle_child_signal): Use the above.
5413 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5414 Moved here from emacs.c.
5415 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5416 code moved here from emacs.c's main function.
5417 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5418 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5419 This lets callers save and restore errno properly.
5421 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5423 Remove redundant or unused things here and there.
5424 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5425 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5426 * editfns.c (Fcompare_buffer_substrings): Likewise.
5427 * frame.h (struct terminal, struct font_driver_list):
5428 Remove redundant declarations.
5429 * window.h (Qleft, Qright): Likewise.

5433 Do not mark objects from deleted buffers, windows and frames.
5434 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5435 (mark_object): Likewise for windows and frames.
5437 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5439 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5440 buffer_defaults and buffer_local_symbols as valid objects.
5441 Return special value to denote them.
5443 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5445 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5446 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5447 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5448 (file_name_absolute_p, Fsubstitute_in_file_name):
5449 (check_executable, check_writable, Ffile_accessible_directory_p)

5451 (Finsert_file_contents, choose_write_coding_system)
5452 (Fwrite_region, build_annotations, a_write, e_write)
5454 * filelock.c (boot_time_initialized, get_boot_time)
5455 (get_boot_time_1, lock_file_1, within_one_second):
5456 * floatfns.c (in_float):
5457 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5458 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5459 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5460 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5461 * window.c (compare_window_configurations):
5462 Use bool for booleans.
5463 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5464 (Fdefault_file_modes): Now mode_t, not int, for modes.
5465 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5466 (internal_delete_file): Now returns void, not a (boolean) int,
5467 since nobody was looking at the return value.
5468 * lisp.h, window.h: Adjust to above API changes.
5470 * xdisp.c (set_message): Simplify and reindent last change.
5472 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5474 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5476 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5478 * eval.c (call_debugger): Make the function non-static so that we
5479 can call it from set_message.
5481 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5482 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5484 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5486 Give more-useful info on a fatal error (Bug#12328).
5487 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5488 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5489 of doing the work ourselves.
5490 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5491 do most of the work.
5492 (fatal_error_backtrace): New function, taken from the guts
5493 of the old fatal_error_signal, but with a new option to output
5495 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5496 info about the signal than just its number.
5497 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5498 * sysdep.c: Include <execinfo.h>
5499 (emacs_backtrace): New function, taken partly from the previous
5500 code of the 'die' function.
5501 (emacs_abort): Call fatal_error_backtrace rather than abort.
5503 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5505 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5506 eager (load-time) macro-expansion.
5507 * lisp.mk (lisp): Add macroexp.
5509 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5511 Simplify redefinition of 'abort' (Bug#12316).
5512 Do not try to redefine the 'abort' function. Instead, redo
5513 the code so that it calls 'emacs_abort' rather than 'abort'.
5514 This removes the need for the NO_ABORT configure-time macro
5515 and makes it easier to change the abort code to do a backtrace.
5516 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5517 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5518 Remove; sysdep.c's emacs_abort now takes its place.
5519 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5520 'abort' changed to use 'emacs_abort'.
5521 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5522 (abort) [!defined abort]: Rename to ...
5523 (emacs_abort): ... new name.
5524 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5525 the place of the old 'abort' in emacs.c.
5526 * w32.c, w32fns.c (abort): Do not #undef.
5527 * w32.c (emacs_abort): Rename from w32_abort.
5529 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5531 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5532 offsets[j].dv, since the y axis of the screen coordinates points
5533 down, while the y axis of the font definition coordinates points
5534 up. This fixes display of Arabic diacritics such as KASRA and
5535 KASRATAN. (Bug#11860)
5537 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5539 Be more systematic about _setjmp vs setjmp.
5540 * alloc.c (test_setjmp, mark_stack):
5541 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5542 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5543 (png_load, my_error_exit, jpeg_load):
5544 * process.c (send_process_trap, send_process):
5545 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5546 The underscored versions are up to 30x faster on some hosts.
5547 Formerly, the code used setjmp+longjmp sometimes and
5548 _setjmp+_longjmp at other times, with no particular reason to
5549 prefer setjmp+longjmp.
5551 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5553 Fix minor problem found by static checking.
5554 * buffer.c (Fdelete_all_overlays): Return nil.
5556 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5558 * buffer.c (Fdelete_all_overlays): New function.
5560 2012-09-03 Chong Yidong <cyd@gnu.org>
5562 * gtkutil.c: Add extern decl for Qxft.
5564 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5579 * eval.c (interactive_p): Omit always-true boolean argument
5580 EXCLUDE_SUBRS_P. All callers changed.
5581 * dispextern.h, lisp.h: Reflect above API changes.
5582 * firstfile.c (dummy): Use the address of 'main', whose signature
5583 won't change, instead of the address of 'initialize', whose
5584 signature just changed from int to bool.
5585 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5586 * msdos.c (fatal_error_in_progress): ... from here.
5587 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5589 (redisplay_internal, unwind_redisplay): Simply clear
5590 REDISPLAYING_P when unwinding, instead of saving its previous,
5591 always-false value and then restoring it.
5593 Clean up some extern decls.
5594 Mostly, this hoists extern decls out of .c files and into .h files.
5595 That way, we're more likely to catch errors if the interfaces change.
5596 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5597 declare xg_mark_data.
5598 * dispextern.h (x_frame_parm_handlers):
5600 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

5616 * xfont.c (x_clear_errors):
5617 * xterm.c (x_frame_parm_handlers):
5618 Remove now-redundant extern decls.
5619 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5620 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5622 * xfaces.c: Remove unnecessary static decls.
5623 * xterm.c (updating_frame): Remove decl of nonexistent object.
5625 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5626 when building globals.h, as the objects that are not built on
5627 this host are not needed to compile C files on this host.
5629 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5631 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5669 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5671 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5679 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5681 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5682 more than one grapheme cluster passed to the shaper: compute the
5683 offset adjustment values separately for each cluster. (Bug#11860)
5685 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5686 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5687 about implicit conversions from integer to pointer.
5689 2012-09-01 Daniel Colascione <dancol@dancol.org>
5691 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5692 system used too early.
5694 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5696 Better seed support for (random).

5738 window-system headers.

5741 window-system headers. Declare Vlibrary_cache when compiling for
5744 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
5745 window system declarations.
5747 * frame.h: Move common functions here: set_frame_menubar,
5748 x_set_window_size, x_sync, x_get_focus_frame,
5749 x_set_mouse_position, x_set_mouse_pixel_position,
5750 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5774 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5776 Remove mark_ttys function and fix tty_display_info initialization.
5777 * lisp.h (mark_ttys): Remove prototype.
5778 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5779 to mark_ttys because all possible values of 'top_frame' slot are
5780 the frames which are reachable from Vframe_list.
5781 * term.c (mark_ttys): Remove.
5782 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5784 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

5789 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
5790 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
5791 bitfields from unsigned char to unsigned.

5809 2012-08-30 Glenn Morris <rgm@gnu.org>
5811 * lread.c (init_lread): For out-of-tree builds, only add the
5812 source directory's site-lisp dir to the load-path if it exists,
5813 consistent with in-tree builds. (Bug#12302)
5815 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5817 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5832 (timeout_handler:): Set timer_fired to YES.
5833 (runDialogAt:): Set timer_fired to NO.
5834 Handle click on close button as quit.
5836 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5837 Add window_closed and button_values. Add void as return value for
5838 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5839 Add process_dialog as new member.
5841 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5843 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5946 Use bool for booleans.
5947 * dired.c (file_name_completion):
5948 * process.h (fd_callback):
5949 Omit int (actually boolean) argument. It wasn't being used.
5951 * composite.h, lisp.h: Reflect above API changes.
5953 * cmds.c, coding.c: Use bool for booleans.

5974 (Fset_coding_system_priority):
5975 * fileio.c (Finsert_file_contents):
5976 Use bool for booleans.
5977 * coding.h, lisp.h: Reflect above API changes.
5978 * coding.c: Remove unnecessary static function decls.
5979 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5980 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5981 not a boolean 'int', since callers never look at the return value.
5982 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5983 * coding.h (decoding_buffer_size, encoding_buffer_size)
5984 (emacs_mule_string_char): Remove unused extern decls.
5985 (struct iso_2022_spec, struct coding_system):
5986 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5987 (struct emacs_mule_spec): Remove unused field 'full_support'.
5988 All initializations removed.
5989 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5991 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5993 Fix spare memory change (Bug#12286).
5994 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5995 (valid_lisp_object_p): Likewise.
5997 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5999 * window.c (Fset_window_configuration): Record any window's old
6000 buffer if it's replaced (see Bug#8789). If the new current
6001 buffer doesn't appear in the selected window, go to its old
6004 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6006 Special MEM_TYPE_SPARE to denote reserved memory.
6007 * alloc.c (enum mem_type): New memory type.
6008 (refill_memory_reserve): Use new type for spare memory.
6009 This prevents live_cons_p and live_string_p from incorrect
6010 detection of uninitialized objects from spare memory as live.
6012 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6015 * Makefile.in (.PHONY): versioclean -> versionclean.
6017 Remove unused external symbols.
6018 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6019 * window.c (Qwindow_valid_p, decode_valid_window):
6020 Now static, not extern.
6021 * data.c (Qinterval): Remove; unused.
6022 (syms_of_data): Do not define 'interval'.
6023 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6024 * window.h (decode_valid_window):
6027 * character.c, charset.c, chartab.c: Use bool for booleans.
6028 * character.c (lisp_string_width, string_count_byte8)

6037 (char_table_set_range, optimize_sub_char_table)
6038 (map_sub_char_table):
6039 Use bool for boolean.
6040 * character.c (str_to_unibyte): Omit last boolean argument; it was
6041 always 0. All callers changed.
6042 * character.h, charset.h: Adjust to match previous changes.
6043 * character.h (char_printable_p): Remove decl of nonexistent function.
6044 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6045 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6046 are all boolean, so make them single-bit bitfields.
6048 * lisp.h (ASET): Remove attempt to detect side effects.
6049 It was meant to be temporary and it often doesn't work,
6050 because when IDX has side effects the behavior of IDX==IDX
6051 is undefined. See Stefan Monnier in
6052 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6054 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6056 * lisp.h (functionp): New function (extracted from Ffunctionp).
6057 (FUNCTIONP): Use it.
6058 * eval.c (Ffunctionp): Use it.
6060 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6062 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6063 as that's faster and simpler than static storage. Don't bother
6064 with the g_main_context_query overhead if g_main_context_pending
6065 says no events are pending.
6066 (gfds, gfds_size): Remove these static vars.
6067 (xgselect_initialize): Remove; no longer needed.
6068 All uses and decls removed.
6070 * emacs.c (fatal_error_signal_hook): Remove.
6071 All uses removed. This leftover from old code was always 0.
6073 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6074 * casefiddle.c (casify_object, casify_region):
6075 * casetab.c (set_case_table):
6076 * category.c, category.h (word_boundary_p):
6077 * category.h (CHAR_HAS_CATEGORY):
6078 Use bool for booleans, instead of int.
6080 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6082 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6084 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6086 On assertion failure, print backtrace if available.
6087 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6088 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6089 * Makefile.in (LIB_EXECINFO): New macro.
6092 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6093 * bytecode.c (exec_byte_code):
6094 * callint.c (check_mark, Fcall_interactively):
6095 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6096 (getenv_internal, sync_process_alive, call_process_exited):
6097 * lisp.h (USE_SAFE_ALLOCA):
6098 Use bool for booleans, instead of int.
6099 * lisp.h, process.h: Adjust prototypes to match above changes.
6100 * callint.c (Fcall_interactively): Don't assume the mark's
6101 offset fits in 'int'.
6103 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6105 * buffer.c, buffer.h: Use bool for boolean.
6106 * buffer.c (reset_buffer_local_variables)
6107 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6108 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

6110 (overlay_touches_p, overlay_strings, Foverlay_put)
6111 (report_overlay_modification, call_overlay_mod_hooks):
6112 (mmap_enlarge, mmap_set_vars):
6113 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6114 Use bool for booleans, instead of int.
6115 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6116 since the 1-or-0 return value is always ignored anyway.
6117 (mmap_initialized_p):
6118 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6119 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6121 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6123 * bidi.c: Use bool for boolean.
6124 This is a bit more readable, and makes the text segment of bidi.o
6125 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6126 Presumably it's faster too.
6127 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6129 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6130 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6131 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6132 (bidi_explicit_dir_char, bidi_level_of_next_char)
6133 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6134 Use bool for booleans, instead of int.
6135 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6136 (bidi_unshelve_cache): Adjust decls to match code.
6138 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6140 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6143 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6145 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6146 * atimer.h: Include <stdbool.h>.
6148 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6150 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6151 compile time tests instead of run time tests on systems that do
6153 (FRAME_MAC_P): Remove leftover from deleted code.
6154 * frame.c (syms_of_frame): Remove leftover from deleted code.
6156 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6158 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6160 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6162 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6163 Otherwise, the compiler complains about (A?B:C) where B is void
6164 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6165 (fontset_add): Return void, for FONTSET_ADD.
6167 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6169 * alloc.c: Use bool for booleans.
6170 (gc_in_progress, abort_on_gc)
6171 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6172 (dont_register_blocks) [GC_MALLOC_CHECK]:
6173 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6174 (check_string_bytes, make_specified_string, memory_full)
6175 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6176 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6177 (mark_stack, valid_pointer_p, make_pure_string)
6178 (Fgarbage_collect, survives_gc_p, gc_sweep):
6179 Use bool for booleans, instead of int.
6180 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6181 Remove unused local.
6182 * alloc.c (PURE_POINTER_P):
6183 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6184 * editfns.c (Fformat):
6185 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6187 * fns.c (sweep_weak_table):
6188 * lisp.h (suppress_checking, push_message, survives_gc_p)
6189 (make_pure_string, gc_in_progress, abort_on_gc):
6190 * lread.c (readchar, read1):
6191 * print.c (Fprin1_to_string):
6192 * xdisp.c (push_message):
6193 Use bool for booleans affected directly or indirectly by
6196 Make recently-introduced setters macros.
6197 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6198 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6199 (set_fontset_default, set_fontset_fallback): Rename from their
6200 upper-case counterparts, and make them functions rather than macros.
6201 This is more consistent with the other recently-introduced setters.
6202 These don't need to be inline, since they're local.
6204 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6206 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6207 the loop (Bug#12247).
6209 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6211 * lisp.h (vcopy): Use memcpy rather than our own loop.
6212 This fixes a performance regression introduced by the recent
6213 addition of vcopy. This means 'vcopy' will need to be modified
6214 for a copying collector, but that's OK. Also, tighten the
6215 checking in the assertion.
6217 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6219 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6220 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6221 non-base glyph for the width of the base character, according to
6222 what x_draw_composite_glyph_string_foreground expects.
6223 Generate WADJUST value according to composition_gstring_width's
6224 expectations, to produce correct width of the composed character.
6225 Reverse the sign of the DU offset produced by ScriptPlace.
6227 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6229 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6231 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6233 Avoid direct writes to contents member of struct Lisp_Vector.
6234 * lisp.h (vcopy): New function to copy data into vector.
6235 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6236 * fns.c (Ffillarray): Use ASET.
6237 * keyboard.c (timer_check_2): Use AREF and ASET.
6238 (append_tool_bar_item, Frecent_keys): Use vcopy.
6239 * lread.c (read_vector): Use ASET.
6240 * msdos.c (Frecent_doskeys): Use vcopy.
6241 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6242 (Finternal_merge_in_global_face): Use ASET and vcopy.
6243 * xfont.c (xfont_list_pattern): Likewise.
6245 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6247 * window.c (Fwindow_point): For the selected window always return
6248 the position of its buffer's point.
6249 (Fset_window_point): For the selected window always go in its
6250 buffer to the specified position.
6252 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6254 Setter macros for fontsets.
6255 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6256 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6257 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6260 2012-08-20 Glenn Morris <rgm@gnu.org>
6262 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6263 Don't assume that `ln -f' works.
6265 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6267 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6268 and later about non-assignments with no effect. See discussion at
6269 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6272 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6274 Inline setter functions for Lisp_Objects slots of struct specbinding.
6275 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6278 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6280 * window.c (select_window): Always make selected window's buffer
6283 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6285 Use AREF and ASET for docstrings of category tables.
6286 * category.h (CATEGORY_DOCSTRING): Use AREF.
6287 (SET_CATEGORY_DOCSTRING): Use ASET.
6288 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6290 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6292 Inline setter functions for hash table members.
6293 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6294 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6295 (set_hash_key_and_value, set_hash_index, set_hash_next)
6296 (set_hash_hash): New functions.
6297 * charset.c, fns.c: Adjust users.
6299 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6301 Inline getter and setter functions for per-buffer values.
6302 * buffer.h (per_buffer_default, set_per_buffer_default)
6303 (per_buffer_value, set_per_buffer_value): New functions.
6304 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6305 * buffer.c, data.c: Adjust users.
6307 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6309 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6311 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6313 Rely on <config.h> + <unistd.h> to declare 'environ',
6314 as gnulib does this if the system doesn't.
6315 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6316 Remove declaration. MS-Windows declares it on stdlib.h which is
6317 included by conf_post.h.
6318 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6319 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6320 * vm-limit.c: Include <unistd.h>, for 'environ'.
6322 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6323 (start_of_data): Remove decl; mem-limits.h provides it.
6325 * xdisp.c (handle_invisible_prop): Make it a bit faster
6326 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6328 2012-08-19 Chong Yidong <cyd@gnu.org>
6330 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6333 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6335 * .gdbinit: Use call instead of set when calling a function in the
6338 * data.c (set_internal): Don't use set_blv_found.
6339 (Fkill_local_variable): Likewise.
6341 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6343 * nsfont.m (ns_ascii_average_width): Ensure the string
6344 ascii_printable is initialized with a null-terminated character
6345 array. Otherwise, it can contain undesired extra characters.
6347 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6349 port new setting code to Sun C 5.8 2005/10/13
6350 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6351 Return void, not Lisp_Object. Otherwise, the compiler
6352 complains about (A?B:C) where B is void and C is Lisp_Object
6353 when compiling CHAR_TABLE_SET, due to the recent change to
6354 the API of sub_char_table_set_contents.
6356 2012-08-18 Chong Yidong <cyd@gnu.org>
6358 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6359 for the string case (Bug#3874).
6361 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6363 * buffer.h (BSET): Remove (Bug#12215).
6364 Replace all uses with calls to new setter functions.

7245 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7246 more like a function. This is because the pointer cast is not
7247 needed. All uses changed.
7248 * print.c (print_string, print_error_message): Avoid length recalc.
7250 Improve fix for macroexp crash with debugging (Bug#12118).
7251 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7252 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7253 not supposed to be invoked from the garbage collector.
7254 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7255 (gc_aset): New function, which is like ASET but can be
7256 used in the garbage collector.

7285 with addition of handling of symlinks and support for 'lstat'.
7286 If possible, get file's attributes and security information by
7287 handle, not by name. Produce S_IFLNK bit for symlinks, when
7288 called from 'lstat'.
7289 (stat, lstat): New functions, call 'stat_worker'.
7290 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7291 symlinks when the underlying filesystem supports them.

7295 Fix macroexp crash on Windows with debugging (Bug#12118).
7296 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7297 checking subscripts; problem introduced with the recent
7298 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7299 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7300 since it's used in non-static inline functions now.
7302 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7303 Don't assume buffer size fits in 'int'. Remove unused local.

7323 * composite.c (COMPOSITE_INLINE):
7324 * dispnew.c (DISPEXTERN_INLINE):
7325 * sysdep.c (SYSTIME_INLINE):
7326 Define to EXTERN_INLINE, so that the corresponding functions
7327 are compiled into code.

7329 (INLINE_HEADER_END): New macros.
7330 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7352 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7354 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7355 This how ASET and AREF are supposed to work, and makes
7356 it easier to think about future improvements. See
7357 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7358 * charset.h (set_charset_attr): New function.

7740 (w32_kbd_patch_key, key_event): Use the codepage returned by
7741 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

7773 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7774 enumeration constants, as PURE and HEAP are too general, and clash
7775 with other headers and sources, such as gmalloc.c and the
7776 MS-Windows system headers. All users changed.
7778 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7780 Revert last save_excursion_save and save_excursion_restore changes.
7781 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7794 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7795 arms of an 'if', not using conditional expressions; otherwise GDB
7796 complains about the types in the unevaluated arm when the argument
7797 is an integer literal.
7798 (xgetint): Simplify expression.
7799 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7800 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7801 Zaretskii in <http://bugs.gnu.org/12036#13>.
7802 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7803 needed now that we have gdb_make_enums_visible.
7804 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7805 (enum enum_USE_LSB_TAG):
7806 New enum types, packaging up enums that need to be exported to GDB.

7848 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7849 emacs.c, as this is a more-suitable home. Had this been done earlier
7850 the fix for 12036 would have avoided some of the problems noted in
7851 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7852 would have been more obvious.
7853 * emacs.c: Do not include <verify.h>; no longer needed.
7854 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7855 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7856 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

7861 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7862 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7863 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7864 not be usable in #if. This simplifies things.
7866 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7868 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7873 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7874 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7875 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7876 Adjust to changes in lisp.h and emacs.c, by using
7877 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7878 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7879 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7880 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7881 instead of gdb_valbits.
7882 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7883 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7884 instead of gdb_array_mark_flag.
7885 (xboolvector): Get size from $->size, not $->header.size.
7886 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7887 (xreload, hook-run, hookpost-run): Remove.
7888 * emacs.c: Include <verify.h>.
7889 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7890 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7892 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7893 (gdb_USE_LSB_TAG): New enum constants.
7894 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7895 Also define these as enum constants, so they're visible to GDB.
7896 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7897 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7898 as constants, so they're visible to GDB.

7901 Now enum constants, not macros, so they're visible to GDB.
7902 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7903 more convenient now. All uses changed.
7904 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7905 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7907 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7914 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7915 add argument, tune behavior, and adjust all callers.
7917 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7919 Use typedef for EMACS_INT, EMACS_UINT.
7920 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7921 than macros. This simplifies debugging in the usual case, since
7922 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7923 and it allows expressions involving EMACS_INT casts.
7924 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7926 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7936 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7938 Adjust buffer text indirection counters at the end of Fkill_buffer.
7939 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7940 buffer is definitely dead. This should really fix an issue reported
7941 by Christoph Scholtes again. (Bug#12007).
7942 (init_buffer_once): Initialize indirection counters of
7943 buffer_defaults and buffer_local_symbols (for sanity and safety).
7945 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7947 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7948 and continuation glyphs on tooltip frames, leave them at zero.

7976 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7978 Swap buffer text indirection counters in Fbuffer_swap_text.
7979 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7980 This avoids crash reported by Christoph Scholtes at
7981 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7983 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7985 * nsmenu.m (Popdown_data): New struct.
7986 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7988 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7989 (initWithContentRect): Make imgView and contentView non-static
7990 and autorelease them. Also autorelease img and matrix (Bug#12005).
7991 (dealloc): Remove (Bug#12005).
7993 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7995 Adjust consing_since_gc when objects are explicitly freed.

8008 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8010 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8011 as it's limited by the amount of memory, not by INT_MAX.
8013 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8015 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8016 in special-event-map. See the discussion at

8075 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8076 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8077 Adjust users accordingly.

8097 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8098 'for_each_per_buffer_object_at'.

8669 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
8670 since nothing has defined it on these platforms.

8739 * s/aix4-2.h (unix): Remove; no longer needed.
8741 EMACS_TIME simplification (Bug#11875).
8742 This replaces macros (which typically do not work in GDB)
8743 with functions, typedefs and enums, making the code easier to debug.
8744 The functional style also makes code easier to read and maintain.
8745 * systime.h: Include <sys/time.h> on all hosts, not just if
8746 WINDOWSNT, since 'struct timeval' is needed in general.

8759 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8760 not functions. All uses rewritten to use the following, respectively:
8761 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8762 (add_emacs_time, sub_emacs_time): New functions.
8763 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8764 * fileio.c (Fcopy_file):
8765 * xterm.c (XTflash): Get the current time closer to when it's used.
8766 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8781 (menu_separator_name_p):
8782 * nsmenu.m (ns_update_menubar):
8783 Prefer memcmp to strncmp when either will do.
8784 * nsterm.m: Include <ftoastr.h>.
8786 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8787 Prefer snprintf to strncpy.
8788 * nsterm.m (ns_term_init):
8789 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8790 * nsterm.m (ns_term_init):
8791 Avoid the need for strncpy, by using build_string or
8792 make_unibyte_string directly. Use dtoastr, not snprintf.
8793 * process.c (Fmake_network_process): Diagnose service names that
8794 are too long, rather than silently truncating them or creating
8795 non-null-terminated names.
8796 (Fnetwork_interface_info): Likewise, for interface names.
8797 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8798 Prefer sprintf to strncat.

8805 Clarify fallback case.
8807 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

8811 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8812 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8813 where argument type is known to be a Lisp_Cons.

8825 Optimize pure C strings initialization.
8826 * lisp.h (make_pure_string): Fix prototype.
8827 (build_pure_c_string): New function, defined as static inline. This
8828 provides a better opportunity to optimize away calls to strlen when
8829 the function is called with compile-time constant argument.
8830 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8831 argument, adjust users accordingly. Use build_pure_c_string where

8834 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8835 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8837 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8839 Avoid calls to strlen in miscellaneous functions.
8840 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

8864 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8865 We include usg5-4-common.h, which defines them both.
8867 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8868 O_RDONLY already includes it).
8870 Stop ns builds setting the EMACSLOADPATH environment variable.
8871 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8872 Now it does not set EMACSLOADPATH, just returns the load-path string.
8873 * nsterm.h: Update accordingly.
8874 * lread.c [HAVE_NS]: Include nsterm.h.
8875 (init_lread) [HAVE_NS]: Use ns_load_path.

8878 2012-07-09 Glenn Morris <rgm@gnu.org>
8880 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8881 since the included bsd-common.h does so.
8883 Stop ns builds setting the EMACSPATH environment variable.
8884 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8885 (ns_init_paths): Do not set EMACSPATH.
8886 * nsterm.h (ns_exec_path): Add it.
8887 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8890 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8892 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8894 * process.c (wait_reading_process_output): 'waitchannels' was unset
8895 when read_kbd || !NILP (wait_for_cell); fix this.
8897 Add GCC-style 'const' attribute to functions that can use it.
8898 * character.h (char_resolve_modifier_mask):
8899 * keyboard.h (make_ctrl_char):
8900 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8911 Minor improvements to make_formatted_string.
8912 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t

8914 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8916 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>

8945 Move marker debugging code under MARKER_DEBUG.
8946 * marker.c (MARKER_DEBUG): Move marker debugging code under
8947 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8948 for bootstrap with --enable-checking (~3x slowdown reported
8949 by Juanma Barranquero <lekktu@gmail.com>).
8950 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8952 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8954 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.

8959 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8960 has no font, use the frame's font. (Bug#11813)
8961 (display_line): Add commentary about displaying truncation glyphs
8963 (produce_special_glyphs): Move here from term.c.
8965 * term.c (produce_special_glyphs): Move to xdisp.c.
8967 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8970 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8972 * xdisp.c (display_line): Avoid warning about implicit declaration
8975 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8977 * lisp.h: Remove empty conditional.
8979 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8981 * lread.c (load_path_check): Now static.
8983 Fix some minor --with-ns problems found by static checking.

8986 * image.c (xpm_load_image) [HAVE_NS]:
8987 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8988 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8989 Remove unused local.

9000 2012-07-07 Glenn Morris <rgm@gnu.org>
9002 * lread.c (load_path_check): New function, split from init_lread.
9003 (init_lread): Reorganize. Motivation:
9004 If EMACSLOADPATH is set, check/warn about that rather than the
9005 defaults, which we are not going to use. Hence we can remove
9006 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9007 Don't warn if site-lisp directories are missing.
9008 If not installed, start from a blank load-path, since
9009 PATH_LOADSEARCH refers to the eventual installation directories.
9011 2012-07-07 Eli Zaretskii <eliz@gnu.org>

9020 GUI frame without a fringe to display continuation or truncation
9022 (insert_left_trunc_glyphs): Support GUI frames: make sure
9023 truncation glyphs overwrite enough glyphs from the current line to
9024 have sufficient space in pixels.
9025 (display_line): Support truncation and continuation glyphs on GUI
9026 frames. If some spare pixels are left on the line after inserting
9027 the truncation glyphs, fill that space with a stretch glyph of a
9028 suitably computed width.
9030 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9031 produce_glyphs, to support GUI sessions.
9033 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9035 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9037 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9039 Do not require float-time's arg to fit in time_t (Bug#11825).
9040 This works better on hosts where time_t is unsigned, and where
9041 float-time is applied to the (negative) difference between two times.
9042 * editfns.c (decode_time_components): Last arg is now double *,
9043 not int *, and means to store all the result as a double, without
9044 worrying about whether the seconds part fits in time_t.
9045 All callers changed.
9046 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9047 All callers changed.
9048 (Ffloat_time): Do not fail merely because the specified time falls
9049 outside of time_t range.
9051 2012-07-07 Glenn Morris <rgm@gnu.org>
9053 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9068 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9069 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9070 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

9073 * xfont.c (compare_font_names): Redo to omit the need for casts.
9075 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9077 * xfns.c (Fx_change_window_property): Doc fix.
9078 * w32fns.c (Fx_change_window_property): Doc fix.
9080 * w32fns.c (Fx_window_property): Accept the same arguments as the
9081 X Windows version. Doc fix.
9082 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9084 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9085 Eli Zaretskii <eliz@gnu.org>
9087 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9088 Windows-specific code from nt/config.nt moved here.
9089 Obsolete settings removed.
9091 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9093 * process.c: Avoid unnecessary calls to gettime.
9094 (wait_reading_process_output): Don't get the time of day
9095 when gobbling data immediately and not waiting, as there's no need
9096 for it in that case. This removes a FIXME.
9098 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9100 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9101 is defined (Bug#11768).

9105 Fix marker debugging code.
9106 * marker.c (byte_char_debug_check): Do not perform the check
9107 if buffer is not multibyte.
9108 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9109 Call byte_char_debug_check with correct arguments.
9111 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9113 Compile marker debugging code only if ENABLE_CHECKING is defined.
9114 * marker.c (byte_char_debug_check, count_markers):
9115 Use only if ENABLE_CHECKING is defined.
9116 (byte_debug_flag): Remove.
9117 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9118 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9120 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9122 Avoid code repetition in marker-related functions.
9123 * marker.c (attach_marker): New function.
9124 (Fset_marker, set_marker_restricted, set_marker_both)
9125 (set_marker_restricted_both): Use it.
9126 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9127 Consistently rename charno to charpos.
9128 (marker_position): Add eassert.
9129 (marker_byte_position): Convert to eassert.

9141 * lisp.h (build_marker): New prototype.
9142 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9143 * composite.c (autocmp_chars): Likewise.
9144 * editfns.c (buildmark): Remove.
9145 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9146 (save_restriction_save): Use build_marker.
9147 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9148 * window.c (save_window_save): Likewise.
9150 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9152 Do not use Fdelete_overlay in delete_all_overlays
9153 to avoid redundant calls to unchain_overlay.
9154 * buffer.c (drop_overlay): New function.
9155 (delete_all_overlays, Fdelete_overlay): Use it.
9156 * minibuf.c (get_minibuffer): Fix comment.
9158 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9160 Port to OpenBSD 5.1 amd64.
9161 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9162 This is needed for OpenBSD, and should be harmless on all BSD systems.
9163 Also, include <sys/sysctl.h>, as it should be available on all
9164 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9165 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9166 use p_pid member, not kp_proc.pid.
9168 2012-07-06 Glenn Morris <rgm@gnu.org>
9170 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9172 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9174 More xmalloc and related cleanup.
9175 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9182 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9183 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9185 Omit needless casts involving void * pointers and allocation.
9186 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9187 as the former is more robust if P's type is changed.
9188 Prefer xzalloc to xmalloc + memset 0.
9189 Simplify malloc-or-realloc to realloc.
9190 Don't worry about xmalloc returning a null pointer.
9191 Prefer xstrdup to xmalloc + strcpy.
9192 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9194 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9195 alloca of a constant.
9197 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9199 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9200 hscroll is larger than the line width. Fixes long and futile
9201 looping inside extend_face_to_end_of_line (on a TTY) producing
9202 glyphs that are not needed and thrown away.
9204 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9206 * marker.c (set_marker_restricted_both): Simplify by using
9209 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9218 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9219 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9220 followed by gtk_box_set_homogeneous (Bug#11768).
9221 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9222 (update_theme_scrollbar_width, xg_create_scroll_bar):
9223 Use gtk_scrollbar_new (Bug#11768).
9224 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9225 (is_box_type): New function (Bug#11768).
9226 (xg_tool_item_stale_p): Call is_box_type.
9227 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9228 with default display (Bug#11768).

9232 * xdisp.c (window_hscroll_limited): New function.
9233 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9234 coordinates when window's hscroll is set to insanely large
9237 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9239 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9298 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9300 * fileio.c (time_error_value): Check the right error number.
9301 Problem reported by Troels Nielsen in
9302 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

9306 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9307 This should be fixed in a better way; see Eli Zaretskii in
9308 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9309 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9311 * fileio.c (time_error_value): Rename from special_mtime.
9312 The old name's problems were noted by Eli Zaretskii in
9313 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9315 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9316 This variable's comment says Emacs needs at least one GDB-visible
9317 symbol of type enum pvec_type, to work around GDB problems.
9318 The symbol's value doesn't matter.
9320 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9321 that causes compilation to fail on pre-C99 compilers.
9323 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9325 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9337 * lisp.h (enum pvec_type): Use fewer bits.
9338 (PSEUDOVECTOR_SIZE_BITS): New constant.
9339 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9340 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9341 change in pvec_type.

9343 (TYPED_PSEUDOVECTORP): Use it.
9344 * fns.c (internal_equal): Adapt code to extract pvectype.
9345 * emacs.c (gdb_pvec_type): Update type.
9346 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9347 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9348 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9349 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9350 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9351 abusing vector->header.next.nbytes.
9352 (live_vector_p): Use PVEC_TYPE.
9353 (mark_object): Adapt code to extract pvectype. Use switch.
9355 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9357 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9358 Tighten new eassert a bit.
9360 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9362 Fix compilation with --enable-gcc-warnings and -O1
9364 * doprnt.c (doprnt): Change type of tem to int, initialize
9365 to avoid compiler warning. Add eassert.
9366 * search.c (simple_search): Initialize match_byte to avoid
9367 compiler warning. Add eassert.
9369 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9371 Avoid weird behavior with large horizontal scrolls.
9372 Without this change, for example, large hscroll values would
9373 mess up Emacs's display on Fedora 15 x86, presumably due to
9374 overflows in int calculations in the display code.
9375 Also, if buffers had long lines, Emacs would freeze.
9376 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9377 (set_window_hscroll): New function, containing the old guts of
9378 Fset_window_hscroll. Return the clipped value.
9379 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9380 This avoids the need to check against PTRDIFF_MAX.
9382 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9384 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

9388 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9390 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9391 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9392 since GCC 4.4.6 issues a bogus warning for them.
9394 Fix bugs in file timestamp newness comparisons.
9395 * fileio.c (Ffile_newer_than_file_p):
9396 * lread.c (Fload): Use full timestamp resolution of files,
9397 not just the 1-second resolution, so that files that are only
9398 slightly newer still count as newer.
9399 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9400 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9402 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9404 * fileio.c: Improve handling of file time marker. (Bug#11852)
9405 (special_mtime): New function.
9406 (Finsert_file_contents, Fverify_visited_file_modtime):
9407 Use it to set special mtime values consistently.
9409 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9411 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9412 marker for non-existing file. (Bug#11852)
9414 2012-07-03 Glenn Morris <rgm@gnu.org>
9416 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9417 and did not make it into globals.h).
9419 2012-07-03 Tom Tromey <tromey@redhat.com>

9457 2012-07-03 Glenn Morris <rgm@gnu.org>
9459 * lisp.h (Frandom): Make it visible to C.
9460 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9461 buffer for invisible buffers. (Bug#1229)

9465 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9466 values which aren't power of 2.
9467 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9468 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9471 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9473 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

9479 * alloc.c (allocate_vector_block): Remove redundant
9480 calls to mallopt if DOUG_LEA_MALLOC is defined.
9481 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9482 avoid calls to mallopt if zero_vector is returned.
9484 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9486 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9487 is enabled, avoid dereferencing NULL current_sblock if
9490 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9492 Cleanup basic buffer management.
9493 * buffer.h (struct buffer): Change layout to use generic vector
9494 marking code. Fix some comments. Change type of 'clip_changed'
9495 to bitfield. Remove unused #ifndef old.
9496 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9497 (GET_OVERLAYS_AT): Fix indentation.
9498 (for_each_per_buffer_object_at): New macro.
9499 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
9500 (Fbuffer_local_variables): Use it.
9501 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9502 * alloc.c (allocate_buffer): Adjust to match new layout of
9503 struct buffer. Fix comment.
9504 (mark_overlay): New function.
9505 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9506 Lisp area of struct buffer.
9507 (mark_object): Use it. Adjust marking of misc objects
9508 and related comments.
9510 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9512 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9513 wrapper that is not needed because the wrapped code is a no-op (zero
9514 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9515 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9517 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9519 * alloc.c (mark_buffer): Simplify. Remove prototype.
9520 (mark_object): Add comment. Reorganize marking of vector-like
9521 objects. Use CHECK_LIVE for all vector-like objects except buffers
9522 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9523 Avoid redundant calls to mark_vectorlike for bool vectors.
9525 2012-06-30 Glenn Morris <rgm@gnu.org>
9527 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9529 * epaths.in (PATH_SITELOADSEARCH): New.
9530 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9531 This is rather than relying on --enable-locallisppath elements
9532 having "site-lisp" in their names. (Bug#10208#25, 11658)
9534 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9536 * w32proc.c (sys_select): Accept and ignore one more argument.
9538 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9540 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9541 (pselect) [!MS_DOS]: Redirect to sys_select.
9543 * sysdep.c: Don't include dos.h and dosfns.h.
9545 * process.c (sys_select):
9546 * msdos.c (sys_select): Accept one more argument and ignore it.
9548 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9549 adapt data types and code to that.
9552 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9553 which clashes with the gnulib function of the same name.
9555 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9557 * font.c (font_style_to_value, font_style_symbolic)
9558 (font_prop_validate_style): Add type checks for values in
9561 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9563 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9566 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9568 * xdisp.c (try_window_id): Undo last change.
9570 * w32.c (getwd): Adjust commentary about startup_dir.
9571 (init_environment): Always call sys_access, even in non-MSVC
9572 builds. Don't chdir to the directory of the Emacs executable.
9573 This undoes code from 1997 which was justified by the need to
9574 "avoid conflicts when removing and renaming directories". But its
9575 downside was that every relative file name was being interpreted
9576 relative to the directory of the Emacs executable, which can never
9577 be TRT. In particular, it broke sys_access when called with
9578 relative file names.
9579 (sys_access): Map GetLastError to errno.
9581 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9583 * window.h (struct window): Change type of 'fringes_outside_margins'
9584 to bitfield. Fix comment. Adjust users accordingly.
9585 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9587 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9590 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9592 * gnutls.c (emacs_gnutls_handshake):
9593 Add QUIT to make the loop interruptible.
9595 2012-06-29 Glenn Morris <rgm@gnu.org>
9597 * charset.c (init_charset): Make lack of etc/charsets fatal.
9599 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9601 * editfns.c (region_limit): Fix type mismatch.
9603 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9605 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9606 undefined. Convert from xassert to eassert.
9607 * nsmenu.m: Convert from xassert to eassert.
9608 * nsterm.m: Likewise.
9610 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9612 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9614 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9616 Avoid integer overflow on scroll-left and scroll-right.
9617 * window.c (HSCROLL_MAX): New macro.
9618 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9619 overflow when requested scroll falls outside ptrdiff_t range.
9621 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9623 * window.h (struct window): Change type of 'hscroll',
9624 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9625 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9626 Adjust users accordingly.
9627 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9628 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9629 from EMACS_INT to ptrdiff_t.
9630 (make_window): Omit redundant initialization.
9632 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9634 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9636 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9638 * window.h (struct window): Change type of 'use_time' and
9639 'sequence_number' from Lisp_Object to int.
9640 * frame.c (make_frame): Adjust users accordingly.
9641 * print.c (print_object): Likewise.
9642 * window.c (select_window, Fwindow_use_time, make_parent_window)
9643 (make_window): Likewise.
9645 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9647 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9648 enabled with --enable-checking=[all,glyphs] configure option.
9649 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9650 adjust comments accordingly.
9651 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
9652 undefined, adjust comments accordingly.

9679 * scroll.c: Likewise.
9680 * sound.c: Likewise.

9689 * xselect.c: Likewise.
9690 * xterm.c: Likewise.
9692 2012-06-27 Stefan Monnier <monnier@iro.umontreal.ca>

9701 avoid GCC warning about unused macro.
9703 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9705 * alloc.c (allocate_string): Omit intervals initialization.
9706 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9707 as in make_pure_string and make_pure_c_string.
9709 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9711 * alloc.c (allocate_string): Fix last change.
9713 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9715 * alloc.c (allocate_string): Remove two redundant calls
9716 to memset, add explicit initialization where appropriate.

9732 when building with Clang.
9734 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

9738 2012-06-26 Eli Zaretskii <eliz@gnu.org>
9740 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
9741 _stricmp and _strnicmp.
9742 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
9744 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9746 * alloc.c (allocate_window): Zero out non-Lisp part of newly
9748 (allocate_process): Likewise for new process.

9759 * term.c (delete_tty): Remove redundant call to memset.
9761 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9763 * alloc.c: Remove build_string.
9764 * lisp.h: Define build_string as static inline. This provides
9765 a better opportunity to optimize away calls to strlen when the
9766 function is called with compile-time constant argument.
9767 * image.c (imagemagick_error): Convert to build_string.
9768 * w32proc.c (sys_spawnve): Likewise.
9769 * xterm.c (x_term_init): Likewise.
9771 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9773 Use sprintf return value instead of invoking strlen on result.
9774 In the old days this wasn't portable, since some sprintf
9775 implementations returned char *. But they died out years ago and
9776 Emacs already assumes sprintf returns int.
9777 Similarly for float_to_string.
9778 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9779 * ccl.c (ccl_driver):
9780 * character.c (string_escape_byte8):
9781 * data.c (Fnumber_to_string):
9782 * doprnt.c (doprnt):
9783 * print.c (print_object):
9784 * xdisp.c (message_dolog):
9785 * xfns.c (syms_of_xfns):
9786 Use sprintf or float_to_string result to avoid need to call strlen.
9787 * data.c (Fnumber_to_string):
9788 Use make_unibyte_string, since the string must be ASCII.
9789 * lisp.h, print.c (float_to_string): Now returns int length.
9790 * term.c (produce_glyphless_glyph):
9791 Use sprintf result rather than recomputing it.
9793 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9794 * Makefile.in (ALL_CFLAGS):
9795 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9796 * gmalloc.c, regex.c: Include <config.h> unconditionally.
9798 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9800 * dispextern.h (xstrcasecmp): Define to library function
9801 strcasecmp if available.
9802 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
9804 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
9806 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):
9807 Avoid comma operator.
9808 * menu.c (push_submenu_start, push_submenu_end)
9809 (push_left_right_boundary, push_menu_pane): Likewise.

9814 * xfns.c (xic_create_fontsetname): Remove redundant calls
9817 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9819 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9820 sprintf already null-terminates its output.
9822 * xfns.c (x_window): Remove redundant cast.
9824 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9826 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9827 `const char *' to `char *' to avoid compiler warning.
9829 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9831 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9832 instead of truncating it to 63 (admittedly a generous limit).
9834 * process.c: Fix spelling and caps in comments.
9836 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9838 * emacs.c (setpgrp): Remove definition, unused.
9839 * sysdep.c (setpgrp): Remove definition, not used in this file.
9841 2012-06-24 Juanma Barranquero <lekktu@gmail.com>
9843 * makefile.w32-in: Update dependencies.

9848 (SYSTIME_H): Add nt/inc/sys/time.h.
9850 * systime.h [WINDOWSNT]: Include sys/time.h.
9852 * s/ms-w32.h (struct timespec): Definition moved from
9853 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
9855 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9857 Switch from NO_RETURN to C11's _Noreturn (Bug#11750).
9858 * buffer.h (buffer_slot_type_mismatch):
9859 * data.c (arith_error) [!FORWARD_SIGNAL_TO_MAIN_THREAD]:
9860 * eval.c (unwind_to_catch):
9861 * image.c (my_png_error, my_error_exit):

9879 * undo.c (user_error):
9880 * unexmacosx.c (unexec_error):
9881 * xterm.c (x_ins_del_lines, x_delete_glyphs):
9882 Use _Noreturn rather than NO_RETURN.
9883 No need for separate decl merely because of _Noreturn.
9884 * sound.c (sound_warning, parse_sound):
9885 Remove unnecessary forward decls.
9887 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9889 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9890 * lisp.h (WAIT_READING_MAX): New macro.
9891 * dispnew.c (Fsleep_for, sit_for):
9892 * keyboard.c (kbd_buffer_get_event):
9893 * process.c (Faccept_process_output):
9894 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9895 This improves on the previous patch, which introduced a bug
9896 when time_t is unsigned and as wide as intmax_t.
9897 See <http://bugs.gnu.org/9000#51>.
9899 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9901 * dispnew.c (sit_for, Fsleep_for):
9902 * keyboard.c (kbd_buffer_get_event):
9903 * process.c (Faccept_process_output): Avoid compiler warnings when
9904 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
9906 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
9908 * makefile.w32-in: Update dependencies.
9910 * w32.c (ltime): Add return type and declare static.
9911 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
9913 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9915 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9916 Privately reported by Herbert J. Skuhra.
9917 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9919 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9920 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9922 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9924 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9925 last argument of make_unibyte_string.
9927 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9928 language ID in the event parameters.
9930 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9931 event.code, not the obscure "character set ID".
9933 2012-06-23 Chong Yidong <cyd@gnu.org>
9935 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9937 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9939 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
9940 * w32.c (fdutimens): New function.
9942 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
9944 * s/ms-w32.h (pselect): Redirect to sys_select.
9946 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
9948 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
9949 in the logic of incrementing and decrementing the value of
9950 use_relocatable_buffers.
9952 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9954 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9955 Privately reported by Herbert J. Skuhra.
9956 [__FreeBSD__]: Remove "*/" typo after "#include".
9957 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
9958 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
9959 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
9960 Don't assume EMACS_TIME and struct timeval are the same type.
9962 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9964 Support higher-resolution time stamps (Bug#9000).
9965 The time stamps are only nanosecond-resolution at the C level,
9966 since that's the best that any real-world system supports now.
9967 But they are picosecond-resolution at the Lisp level, as that's
9968 easy, and leaves room for future OS improvements.
9970 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9973 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9974 Don't get current time unless it's needed.
9976 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9977 now provides it if it's absent.
9978 (start_atimer): Port to higher-res time stamps.
9979 Check for time stamp overflow. Don't get current time more
9980 often than is needed.
9982 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9983 Include systime.h, not time.h.
9984 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9986 * dired.c: Include stat-time.h.
9987 (Ffile-attributes): File times now have higher resolution.
9989 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9990 (struct image): Timestamp now has higher resolution.
9992 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9993 has at least microseconds now. All uses removed.

10005 (make_time): Now static.
10006 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10007 Report an error if the time is invalid, rather than having the caller
10010 * fileio.c: Include <stat-time.h>
10011 (Fcopy_file): Copy higher-resolution time stamps.
10012 Prefer to set the time stamp via a file descriptor if that works.

10026 Check for time stamp overflow.
10027 (read_char, kbd_buffer_get_event, timer_start_idle)
10028 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10029 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10030 Port to higher-resolution time stamps. Do not assume time_t is signed.
10031 (decode_timer): New function. Timers are now vectors of length 9,
10032 not 8, to accommodate the picosecond component.
10033 (timer_check_2): Use it.
10035 * nsterm.m (select_timeout, timeval_subtract): Remove.
10036 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10037 as they're a bit more accurate and handle overflow better.
10038 (ns_select): Change prototype to be compatible with pselect.
10039 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10040 * nsterm.h (ns_select): Adjust prototype.
10042 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes

10057 (wait_reading_process_output):
10058 Port to ns-resolution time stamps.
10059 (Faccept_process_output, wait_reading_process_output):
10060 Check for time stamp overflow. Do not assume time_t is signed.
10061 (select_wrapper): Remove; we now use pselect.
10062 (Fprocess_attributes): Now generates ns-resolution time stamps.
10064 * sysdep.c: Include utimens.h. Don't include utime.h
10065 or worry about struct utimbuf; gnulib does that for us now.
10066 (gettimeofday): Remove; gnulib provides a substitute.
10067 (make_timeval): New function.
10068 (set_file_times): Now sets ns-resolution time stamps.
10069 New arg FD; all uses changed.

10072 Now returns ns-resolution time stamp. All uses changed.
10073 Check for time stamp overflow.
10075 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10076 provides a substitute now.
10078 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10079 since it guarantees struct timespec.
10080 (EMACS_TIME): Now struct timespec, so that we can support
10081 ns-resolution time stamps.
10082 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10083 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10084 (EMACS_USECS): Remove.
10085 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10086 so multiply the arg by 1000 before storing it.
10087 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10089 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10096 (make_timeval, make_lisp_time, decode_time_components): New decls.
10097 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10098 that it mishandled time_t overflow. You can't compare by subtracting!
10099 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10100 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10102 * term.c: Include <sys/time.h>.

10107 in the undo buffer.
10108 (Fprimitive_undo): Use them when restoring time stamps.
10110 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10111 (w32_get_internal_run_time):
10112 Port to higher-resolution Emacs time stamps.
10113 (ltime): Now accepts single 64-bit integer, as that's more convenient
10116 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10118 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10119 for compatibility with pselect. Support ns-resolution time stamps.
10121 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10123 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10124 Check for time stamp overflow, and support ns-resolution time stamps.
10126 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10127 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10128 (timeval_subtract): Remove; no longer needed.
10129 (XTflash, XTring_bell, x_wait_for_event):
10130 Port to ns-resolution time stamps. Don't assume time_t is signed.

10136 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10138 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10139 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10140 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10141 staticidx goes up to 1597 out of 1600 = 0x640.)
10143 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10145 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10146 Otherwise, the umask might be mistakenly 0 while handling input signals.
10148 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10150 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10157 access to `contents' member of Lisp_Vector objects with AREF and ASET
10160 2012-06-19 Chong Yidong <cyd@gnu.org>
10162 * frame.c (delete_frame): When selecting a frame on a different
10163 text terminal, do not alter the terminal's top-frame.

10167 (unwind_format_mode_line): Restore them.
10168 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10170 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10171 since tty frames can be explicitly named.
10172 (prepare_menu_bars): Likewise.
10174 * term.c (Ftty_top_frame): New function.
10176 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

10179 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10180 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10181 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10182 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10183 (METER_1, METER_2): Simplify.
10185 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10187 * data.c (Fdefalias): Return `symbol' (bug#11686).
10189 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10191 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10192 gets killed during executing of this function (Bug#11665).
10193 Try to always return Qt when the buffer has been actually killed.
10194 (Vkill_buffer_query_functions): In doc-string say that functions
10195 run by this hook should not change the current buffer.
10197 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10199 Fix recently-introduced process.c problems found by static checking.

10217 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
10219 * lisp.h (eassert): Assume C89 or later.
10220 This removes the need for CHECK.
10221 (CHECK): Remove. Its comments about always evaluating its
10222 argument were confusing, as 'eassert' typically does not evaluate
10225 * coding.c (produce_chars): Use ptrdiff_t, not int.
10227 * xterm.c (x_draw_underwave): Check for integer overflow.
10228 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10414 as the union type is for debugging, not for production.
10415 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10416 Use an inline function on all platforms when using the union type,
10417 since this is simpler and 'static inline' can be used portably

10559 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10561 * doprnt.c (doprnt): Truncate multibyte char correctly.
10562 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10563 would mishandle a string argument "Xc" if X was a multibyte
10564 character of length 2: it would truncate after X's first byte
10565 rather than including all of X.
10567 2012-06-06 Chong Yidong <cyd@gnu.org>
10569 * buffer.c (word_wrap): Doc fix.

10616 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10618 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10619 Convert pctcpu and pctmem to Lisp float properly.
10620 Let the compiler fold better, as 100.0/0x8000 is exact.
10622 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10624 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10634 bitfields where appropriate, remove unused fields.
10635 * window.h (struct window): Remove unused 'last_mark_x' and
10636 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10637 change its type from Lisp_Object to bitfield.
10638 Change type of 'force_start', 'optional_new_start',
10639 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10640 fields from Lisp_Object to bitfield. Adjust users accordingly.
10642 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10644 Pacify gcc -Wdouble-precision when using Xaw.
10645 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10646 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10647 Use 'float' consistently, rather than 'float' in most places
10648 and 'double' in a couple of places.
10650 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10652 * xdisp.c (handle_stop): Detect whether we have overlay strings
10653 loaded by testing it->current.overlay_string_index to be
10654 non-negative, instead of checking whether n_overlay_strings is
10655 positive. (Bug#11587)
10657 2012-05-31 Chong Yidong <cyd@gnu.org>
10659 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10665 * search.c (search_buffer): Remove calls to
10666 r_alloc_inhibit_buffer_relocation, as it is now called by
10667 maybe_unify_char, which was the cause of relocation of buffer text
10670 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10672 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10673 for the duration of call to load_charset, to avoid problems with
10674 callers of maybe_unify_char that access buffer text through C
10677 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10678 decrement the inhibition flag, instead of just setting or
10681 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10683 Remove obsolete '#define static' cruft.
10684 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10685 This #undef was "temporary" in 2000; it is no longer needed
10686 now that '#define static' has gone away.
10687 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10688 (gray_bitmap_bits): Remove; no longer needed.
10689 All uses replaced with definiens.

10697 Define only on platforms that need it.
10698 * emacs.c: Include <sys/gmon.h> when profiling.
10699 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10700 (__executable_start): Remove decl, since lisp.h does it now.
10701 (safe_bcopy): Remove decl; no longer has that name.
10702 (main): Coalesce #if into single bit of code, for simplicity.
10703 Cast pointers to uintptr_t, since standard libraries want integers
10705 * lisp.h (__executable_start): New decl.
10707 2012-05-31 Glenn Morris <rgm@gnu.org>
10709 * image.c (Fimagemagick_types): Doc fix.

10732 Do not create empty overlays with the evaporate property (Bug#9642).
10733 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10734 Bug#9642, but explicitly check that the buffer the overlay would
10735 be moved to is live and rearrange lines to make sure that errors
10736 will not put the overlay in an inconsistent state.
10737 (Fdelete_overlay): Cosmetics.
10739 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10741 * w32term.c (my_bring_window_to_top): New function.
10742 (x_raise_frame): Use handle returned by DeferWindowPos, which
10743 could be different from the original one.

10756 This avoids undefined behavior that might cause the eassert
10757 to not catch an out-of-range value.
10759 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10761 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

10775 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10776 Only r_alloc_inhibit_buffer_relocation needed to be added;
10777 the others were already declared.
10779 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10780 before checking whether it's out of range. Put the check inside
10782 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10784 2012-05-27 Ken Brown <kbrown@cornell.edu>

10796 they are now on lisp.h.
10798 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10800 * search.c (search_buffer): Use it to inhibit relocation of buffer
10801 text while re_search_2 is doing its job, because re_search_2 is
10802 passed C pointers to buffer text. (Bug#11519)
10804 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10805 Update value to 24.
10807 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10808 state after an additional call to move_it_in_display_line_to, keep
10809 the values of it->max_ascent and it->max_descent found for the
10811 (pos_visible_p): Revert the comparison against bottom_y to what it
10812 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10815 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10817 Fix coding-related core dumps with gcc -ftrapv.
10818 The code was computing A - B, where A and B are pointers, and B is
10819 random garbage. This can lead to core dumps on platforms that
10820 have special pointer registers, and it also leads to core dumps on
10821 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10822 A - B only when B is initialized properly.
10823 * coding.c (coding_set_source, coding_set_destination): Return void.
10824 (coding_change_source, coding_change_destinations): New functions,
10825 with the old behaviors of coding_set_source and coding_set_destination.

10836 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10838 * w32console.c: Include window.h.
10839 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10841 (initialize_w32_display): Initialize mouse-highlight data.
10843 * w32inevt.c: Include termchar.h and window.h.
10844 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10845 moves, call note_mouse_highlight. If help_echo changed, call
10846 gen_help_event to produce help-echo message in the echo area.
10847 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10850 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10852 * lread.c (read1): Simplify slightly to avoid an overflow warning
10853 with GCC 4.7.0 on x86-64.
10855 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10857 * bidi.c (bidi_mirror_char): Revert last change: an int is
10858 definitely wide enough here.

10868 (make_string_from_bytes, make_specified_string)
10869 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10870 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10872 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10873 (allocate_pseudovector):
10874 Use int, not EMACS_INT, where int is wide enough.
10875 (inhibit_garbage_collection, Fgarbage_collect):
10876 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10877 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10878 int might not be wide enough.
10879 (bidi_cache_search, bidi_cache_find, bidi_init_it)

10896 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10897 (validate_region): Omit unnecessary test for b <= e,
10898 since that's guaranteed by the previous test.
10899 (adjust_overlays_for_delete): Avoid pos + length overflow.
10900 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10901 (report_overlay_modification):
10902 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10903 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10904 Omit pointer cast, which isn't needed anyway, and doesn't work
10905 after the EMACS_INT -> ptrdiff_t change.
10906 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10907 * buffer.h: Adjust decls to match defn changes elsewhere.

10909 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10910 Use EMACS_INT, not int, where int might not be wide enough.
10911 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10912 not int, to avoid needless 32-bit limit on 64-bit hosts.
10913 (exec_byte_code): Use tighter memory-full test, one that checks
10914 for alloca overflow. Don't compute the address of the object just
10915 before an array, as that's not portable. Use EMACS_INT, not
10916 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10917 * callint.c (Fcall_interactively):
10918 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10919 * callproc.c (call_process_kill, Fcall_process):
10920 Don't assume pid_t fits into an Emacs fixnum.

10930 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10931 (casify_object): Avoid integer overflow when overallocating buffer.
10932 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10933 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10934 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10935 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10936 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

10940 For CCL_MapSingle, check that content and value are in int range.
10941 (ccl_driver, Fregister_code_conversion_map):
10942 Check that Vcode_version_map_vector is a vector.
10943 (resolve_symbol_ccl_program): Check that vector header is in range.
10944 Always copy the vector, so that we can check its contents reliably
10945 now rather than having to recheck each instruction as it's being
10946 executed. Check that vector words fit in 'int'.
10947 (ccl_get_compiled_code, Fregister_ccl_program)
10948 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10949 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

10951 contents are in range.
10952 (Fccl_execute_on_string): Check that status is in range.
10953 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10954 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10955 Accept and return EMACS_INT, not int, because callers can pass values
10956 out of 'int' range.

10962 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10964 avoid mishandling large integers.

10974 (Fdefine_charset_internal): Check ranges here, more carefully.
10975 Don't rely on undefined behavior with signed left shift overflow.
10976 Don't assume unsigned int fits into fixnum, or that fixnum fits
10977 into unsigned int. Don't require max_code to be a valid fixnum;
10978 that's not true for gb10830 4-byte on a 32-bit host. Allow
10979 invalid_code to be a cons, for the same reason. Require code_offset
10980 to be a character. Avoid int overflow if max_char is close
10982 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10983 this is intended anyway and avoids some undefined behavior.
10984 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10985 INDEX_TO_CODE_POINT, as that's what it expects.
10986 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10987 * charset.h (DECODE_CHAR): Return int, not unsigned;
10988 this is what was intended anyway, and it avoids undefined behavior.
10989 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10990 integer-overflow issues.
10991 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10992 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10993 where the argument is EMACS_INT, and this behavior is not intended.
10994 * chartab.c (Fmake_char_table, Fset_char_table_range)
10995 (uniprop_get_decoder, uniprop_get_encoder):
10996 Don't assume fixnum fits in int.
10997 * cmds.c (move_point): New function, that does the gist of
10998 Fforward_char and Fbackward_char, but does so while checking
10999 for integer overflow more accurately.
11000 (Fforward_char, Fbackward_char): Use it.
11001 (Fforward_line, Fend_of_line, internal_self_insert)
11002 (internal_self_insert):
11003 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11650 * xterm.c (x_x_to_emacs_modifiers):
11651 Don't assume EMACS_INT overflows nicely into int.
11652 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
11653 may come from Lisp.

11662 2012-05-25 Glenn Morris <rgm@gnu.org>
11664 * lisp.mk (lisp): Update for more files being compiled now.
11666 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11668 * lread.c: Remove `read_pure' which makes no difference.
11669 (read_pure): Remove var.
11670 (unreadpure): Remove function.
11671 (readevalloop): Don't call read_list with -1 flag.
11672 (read1, read_vector): Don't test read_pure any more.

11684 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11686 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11689 This directory predates autoconf and is no longer needed nowadays.
11690 Move its few remaining bits of functionality to where they're needed.
11691 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

11696 * lisp.h (USE_LSB_TAG):
11697 * mem-limits.h (EXCEEDS_LISP_PTR):
11698 Use VAL_MAX, not VALBITS, in #if.
11699 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11700 (EMACS_UINT): Define unconditionally now.
11701 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11702 (BITS_PER_EMACS_INT): New constants, replacing
11703 what used to be in config.h, but not useful in #if.
11704 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11705 define them any more.
11706 (VAL_MAX): New macro.
11708 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11709 BITS_PER_EMACS_INT, in #if.
11710 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11711 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11712 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:

11714 Move here from removed file m/intel386.h.
11715 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11716 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11718 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11720 Assume C89 or later.
11721 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

11745 * xfns.c (x_in_use): Remove `static' qualifier.
11746 * xterm.h (x_in_use): Declare.
11747 * xgselect.c: Include xterm.h.
11748 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11749 and `display_arg' (bug#9754).
11751 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11753 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.

11763 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11765 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11766 reference to image_cache->refcount.
11767 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11769 2012-05-17 Juri Linkov <juri@jurta.org>
11771 * search.c (Fword_search_regexp, Fword_search_backward)
11772 (Fword_search_forward, Fword_search_backward_lax)
11773 (Fword_search_forward_lax): Move functions to isearch.el
11774 (bug#10145, bug#11381).
11776 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11778 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11780 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11782 * lread.c (init_obarray): Declare Qt and Qnil as special.
11784 2012-05-14 Glenn Morris <rgm@gnu.org>
11786 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11787 Put "libexec" before "bin", for the sake of init_callproc_1.
11789 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11791 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11793 * unexaix.c: Port to more-recent AIX compilers.
11794 (report_error, report_error_1, make_hdr, copy_sym)
11795 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11796 Make arguments const char *, not char *, to avoid violations of C
11797 standard and to fix some AIX warnings reported by Gilles Pion.
11799 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11801 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11802 already have overlays loaded.
11803 (handle_single_display_spec): Before returning without displaying
11804 fringe bitmap, synchronize the bidi iterator with the main display
11805 iterator, by calling iterate_out_of_display_property.
11806 (iterate_out_of_display_property): Detect buffer iteration by
11807 testing that it->string is a Lisp string.
11808 (get_next_display_element): When the current object is exhausted,
11809 and there's something on it->stack, call set_iterator_to_next to
11810 proceed with what's on the stack, instead of returning zero.
11811 (set_iterator_to_next): If called at the end of a Lisp string,
11812 proceed to consider_string_end without incrementing string
11813 position. Don't increment display vector index past the end of
11814 the display vector. (Bug#11417)
11815 (pos_visible_p): Don't report a position visible when move_it_to
11816 stopped at the last line of window, which happens to be scanned
11817 backwards by the bidi iteration. (Bug#11464)
11819 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11821 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11822 and right-margin display specs even if the spec is invalid or we
11823 are on a TTY, and thus unable to display on the fringes.
11824 That's because the text with the property will not be displayed anyway,
11825 so we need to signal to the caller that this is a "replacing"
11826 display spec. This fixes display when the spec is invalid or we
11829 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11831 * unexaix.c (make_hdr): Fix typo in prototype.
11832 This bug broke the build on AIX. Problem reported by Gilles Pion.
11834 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11836 * keyboard.c (kbd_buffer_get_event): Read special events also in
11837 batch mode. (Bug#11415)
11839 2012-05-12 Glenn Morris <rgm@gnu.org>
11841 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11843 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11845 * lisp.mk (lisp): Add newcomment.elc.
11847 2012-05-12 Glenn Morris <rgm@gnu.org>
11849 * Makefile.in (MKDIR_P): New, set by configure.
11850 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11852 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11854 Remove unused function hourglass_started.
11855 * dispextern.h (hourglass_started):
11856 * w32fns.c (hourglass_started):
11857 * xdisp.c (hourglass_started): Remove.
11859 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11861 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11862 Update dependencies.
11864 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11866 * xgselect.c (xg_select): Put maxfds+1 into a var.
11867 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11869 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11871 2012-05-10 Dave Abrahams <dave@boostpro.com>
11873 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11874 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11876 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11878 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11879 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11880 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11881 Initialize xd_registered_buses.
11883 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11885 Untag more efficiently if USE_LSB_TAG.
11886 This is based on a proposal by YAMAMOTO Mitsuharu in
11887 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11888 For an admittedly artificial (nth 8000 longlist) benchmark on
11889 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11890 Emacs's overall text size by 1%.
11891 * lisp.h (XUNTAG): New macro.
11892 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11893 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11894 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11895 * eval.c (Fautoload):
11896 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11897 * frame.h (XFRAME): Use XUNTAG.
11899 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11900 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11901 Remove unportable assumptions about print widths of types like
11903 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11904 intptr_t when converting between pointer and integer, to avoid GCC
11905 warnings about wrong width.
11907 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11909 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11910 stack for each reader_thread, instead of defaulting to 8MB
11911 determined by the linker. This avoids failures in creating
11912 subprocesses on Windows 7, see the discussion in this thread:
11913 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11915 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11917 Fix up display of the *Minibuf-0* buffer in the mini window.
11918 * keyboard.c (read_char): Don't clear the echo area if there's no
11920 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11921 contents of *Minibuf-0*) if there's no message displayed in its stead.
11923 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11925 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11928 2012-05-06 Chong Yidong <cyd@gnu.org>
11930 * lisp.mk (lisp): Update.
11932 2012-05-05 Jim Meyering <meyering@redhat.com>
11934 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11936 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11938 * data.c (PUT_ERROR): New macro.
11939 (syms_of_data): Use it. Add new error type `user-error'.
11940 * undo.c (user_error): New function.
11941 (Fprimitive_undo): Use it.
11942 * print.c (print_error_message): Adjust print style for `user-error'.
11943 * keyboard.c (user_error): New function.
11944 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11946 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11948 Do not limit current-time-string to years 1000..9999.
11949 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11950 (Fcurrent_time_string): Support any year that is supported by the
11951 underlying localtime representation. Don't use asctime, as it
11952 has undefined behavior for years outside the range -999..9999.
11954 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11956 Fix race conditions involving setenv, gmtime, localtime, asctime.
11957 Without this fix, interrupts could mess up code that uses these
11958 nonreentrant functions, since setting TZ invalidates existing
11959 tm_zone or tzname values, and since most of these functions return
11960 pointers to static storage.
11961 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11962 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11963 Grow the critical sections to include not just invoking
11964 localtime/gmtime, but also accessing these functions' results
11965 including their tm_zone values if any, and any related TZ setting.
11966 (format_time_string): Last arg is now struct tm *, not struct tm **,
11967 so that the struct tm is saved in the critical section.
11968 All callers changed. Simplify allocation of initial buffer, partly
11969 motivated by the fact that memory allocation needs to be outside
11970 the critical section.
11972 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11974 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11975 with RESET_INTERVAL.
11977 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11978 Remove duplicated buffer name initialization.
11980 2012-05-02 Jim Meyering <jim@meyering.net>
11982 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11984 * xfns.c (x_window): Use xstrdup (Bug#11375).
11986 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11988 * xdisp.c (pos_visible_p): If already at a newline from the
11989 display string before the 'while' loop, don't walk back the glyphs
11990 from it3.glyph_row. Solves assertion violation when the display
11991 string begins with a newline (egg.el). (Bug#11367)
11993 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11995 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11998 2012-05-01 Glenn Morris <rgm@gnu.org>

12001 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12002 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12003 All were removed before 23.1.
12005 * dispnew.c: Remove HAVE_LIBNCURSES test;
12006 it is always true on relevant platforms.
12008 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12009 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12011 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12013 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12015 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12016 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12019 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12021 Do not avoid creating empty evaporating overlays (Bug#9642).
12022 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12023 That is, do not delete an evaporating overlay if it becomes
12024 empty after its bounds are adjusted to fit within its buffer.
12025 This fix caused other problems, and I'm reverting it until we get
12026 to the bottom of them.
12028 2012-04-27 Chong Yidong <cyd@gnu.org>
12030 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12032 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12034 * xdisp.c (pos_visible_p): If the window start position is beyond
12035 ZV, start the display from buffer beginning. Prevents assertion
12036 violation in init_iterator when the minibuffer window is scrolled
12037 via the scroll bar.
12039 * window.c (window_scroll_pixel_based): Likewise.
12041 2012-04-27 Chong Yidong <cyd@gnu.org>
12043 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12045 2012-04-27 Glenn Morris <rgm@gnu.org>
12047 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12048 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12050 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12052 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12053 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12055 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12057 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12058 display element, check also the underlying string or buffer
12059 character. (Bug#11341)
12061 * w32menu.c: Include w32heap.h.
12062 (add_menu_item): If the call to AppendMenuW (via
12063 unicode_append_menu) fails, disable Unicode menus only if we are
12064 running on Windows 9X/Me.
12066 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12068 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12069 (xgetint): Add missing shift for LSB tags.
12071 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12073 * keyboard.c (read_char): Don't wipe echo area for select window
12074 events: These might get delayed via `mouse-autoselect-window'
12077 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12079 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12080 manipulation of :loaded-from data.
12082 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12084 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12085 now a cons (bug#11311).
12087 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12089 Do not create empty overlays with the evaporate property (Bug#9642).
12090 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12091 if it becomes empty after its bounds are adjusted to fit within
12092 its buffer. Without this fix, in a nonempty buffer (let ((o
12093 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12094 yields an empty overlay that has the evaporate property, which is
12095 not supposed to happen.
12097 Fix minor GTK3 problems found by static checking.
12098 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

12117 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12118 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12119 (__malloc_size_t, __malloc_ptrdiff_t):
12120 Remove. All uses removed, replaced by the definiens if needed,
12121 since we can assume C89 or better now.
12122 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12210 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12212 * sysdep.c [__FreeBSD__]: Minor cleanups.
12213 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12214 Use Emacs indenting style more consistently. Avoid some casts.
12215 Use 'double' consistently rather than mixing 'float' and 'double'.
12217 2012-04-21 Eduard Wiebe <usenet@pusto.de>
12219 * sysdep.c (list_system_processes, system_process_attributes):

12226 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12228 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12229 It is never used otherwise.
12231 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12233 * print.c (print_preprocess): Only check print_depth if print-circle
12235 (print_object): Check for cycles even when print-circle is nil and
12236 print-gensym is t, but only check print_depth if print-circle is nil.
12238 2012-04-20 Chong Yidong <cyd@gnu.org>
12240 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12241 set the status to "failed" and ensure that sentinel is run.
12243 2012-04-20 Glenn Morris <rgm@gnu.org>
12245 * process.c (Fset_process_inherit_coding_system_flag)

12254 row, return zero immediately.
12255 (try_cursor_movement): If inside continuation line, don't back up
12256 farther than the first row after the header line, if any.
12257 Don't consider the header-line row as "partially visible", even if

12274 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
12275 -Wunused-result, -Wunused-variable. This should go away once
12276 the Emacs and Gnulib regex code is merged.

12298 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12299 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12300 (NEED_MEM_INSERT): New macro.
12301 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12302 Remove one incorrect comment and fix another.

12306 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
12307 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
12308 (r_alloc_sbrk): Now static.
12310 Improve ralloc.c interface checking.
12311 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
12312 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

12321 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
12323 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

12338 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12339 * s/netbsd.h, s/sol2-6.h:
12340 Remove definition of GC_MARK_STACK, since the default now works.
12341 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12342 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12343 no longer the default.
12344 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12346 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12348 * lread.c (lisp_file_lexically_bound_p):

12369 2012-04-11 Daniel Colascione <dancol@dancol.org>
12371 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12372 against is gone. It's better to use vfork now so that when Cygwin
12373 gains a new, working vfork, we use it automatically (bug#10398).
12375 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12390 (force_quit_count): New var.
12391 (handle_interrupt): Use it.
12393 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
12395 * w32.c (w32_delayed_load): Record the full path of the library
12396 being loaded (bug#10424).
12398 2012-04-09 Glenn Morris <rgm@gnu.org>
12400 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12401 not just in the obarray, before snarfing them. (Bug#11036)
12403 * Makefile.in ($(leimdir)/leim-list.el):
12404 Pass EMACS rather than BUILT_EMACS.
12406 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12408 * process.c (make_process):
12409 * process.h: Add integer `gnutls_handshakes_tried' member to
12412 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
12413 Add convenience `GNUTLS_LOG2i' macro.
12415 * gnutls.c (gnutls_log_function2i): Convenience log function.
12416 (emacs_gnutls_read): Use new log functions,
12417 `gnutls_handshakes_tried' process member, and
12418 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12419 attempts per process (connection).
12421 2012-04-09 Chong Yidong <cyd@gnu.org>
12423 * eval.c (Fuser_variable_p, user_variable_p_eh)

12428 * minibuf.c (Fread_variable): Callers changed.
12430 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12432 * xdisp.c (set_cursor_from_row): If the display string appears in
12433 the buffer at position that is closer to point than the position
12434 after the display string, display the cursor on the first glyph of
12435 the display string. Fixes cursor display when a 'display' text
12436 property immediately follows invisible text. (Bug#11094)
12438 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12440 composite.c: use 'double' consistently
12441 * composite.c (get_composition_id): Use 'double' consistently
12442 instead of converting 'float' to 'double' and vice versa; this is
12443 easier to understand and avoids a GCC warning.
12445 2012-04-09 Glenn Morris <rgm@gnu.org>
12447 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12448 preparation for dumping it with emacs. (Bug#4789)
12449 (leimdir): New variable.
12450 ($(leimdir)/leim-list.el): New rule.
12451 (emacs$(EXEEXT)): Depend on leim-list.el.

12467 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12469 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12470 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12471 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12472 objects, as mark_maybe_pointer will catch them otherwise.
12473 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12474 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12478 Fix typo that broke non-Windows builds.
12479 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
12481 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12483 Support building on MS-Windows with libxml2.
12485 * makefile.w32-in (OBJ2): Add xml.$(O).
12486 (GLOBAL_SOURCES): Add xml.c.
12487 ($(BLD)/xml.$(O)): New dependency list.
12489 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12490 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12491 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12492 [!WINDOWSNT]: New macros.
12493 (init_libxml2_functions, libxml2_loaded_p): New functions.
12494 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12495 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12496 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12497 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12499 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12500 Call init_libxml2_functions before calling libxml2 functions.
12501 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12503 * emacs.c: Don't include libxml/parser.h.
12504 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12505 xmlCleanupParser directly.
12507 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12509 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12511 * indent.c (Fvertical_motion): If there is a display string at
12512 point, use it.vpos to compute how many lines to backtrack after
12513 move_it_to point. (Bug#11133)
12515 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12517 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12518 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12519 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12520 macros related to unification of CJK characters. For the details,
12521 see the discussion following the message here:
12522 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12524 2012-04-04 Chong Yidong <cyd@gnu.org>
12526 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12528 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12530 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12531 instead of alloca. (Bug#11138)
12533 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12535 * w32menu.c (is_simple_dialog): Properly check lisp types.
12538 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12540 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12541 position we get to after a call to move_it_to fails the
12542 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12543 only if we wind up in a string from display property. (Bug#11063)
12545 * window.c (Fdelete_other_windows_internal): Invalidate the row
12546 and column information about mouse highlight, so that redisplay
12547 restores it after reallocating the glyph matrices. (Bug#7464)
12549 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12550 string comes from a `display' text property, use the buffer
12551 position of that property as if we actually saw that position in
12553 (move_it_by_lines): Remove the assertion that
12554 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12555 violated when there's a before-string at the beginning of a line.
12558 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12560 * xdisp.c (append_space_for_newline): If the default face was
12561 remapped, use the remapped face for the appended newline.
12562 (extend_face_to_end_of_line): Use the remapped default face for
12563 extending the face to the end of the line.
12564 (display_line): Call extend_face_to_end_of_line when the default
12565 face was remapped. (Bug#11068)
12567 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12569 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12571 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12573 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12575 2012-03-27 Glenn Morris <rgm@gnu.org>
12577 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12580 2012-03-26 Kenichi Handa <handa@m17n.org>
12582 * dispextern.h (struct glyph): Fix previous change. Change the
12583 bit length of glyphless.ch to 25 (Bug#11082).
12585 2012-03-26 Chong Yidong <cyd@gnu.org>
12587 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12588 (command_loop_1): Use it; inhibit selection update for
12589 handle-select-window too (Bug#8996).
12591 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12593 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12595 2012-03-25 Kenichi Handa <handa@m17n.org>
12597 * dispextern.h (struct glyph): Change the bit length of
12598 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12600 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12602 * s/ms-w32.h (tzname): Include time.h before redirecting to
12603 _tzname. Fixes the MSVC build. (Bug#9960)
12605 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12607 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12610 * xterm.c (XTread_socket): Only modify handling_signal if
12611 !SYNC_INPUT. (Bug#11080)
12613 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12615 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12616 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12617 when fetching a multibyte character consumes more bytes than
12618 CHAR_BYTES returns, due to unification of CJK characters in
12619 string_char. (Bug#11073)
12621 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12623 * process.c (wait_reading_process_output): Handle pty disconnect
12624 by refraining from sending oneself a SIGCHLD (bug#10933).
12626 2012-03-22 Chong Yidong <cyd@gnu.org>

12630 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12631 Mark string as coming from a prefix property.
12632 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12633 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12635 2012-03-21 Chong Yidong <cyd@gnu.org>
12637 * xfaces.c (Vface_remapping_alist): Doc fix.
12639 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12641 * w32proc.c (Fw32_set_console_codepage)
12642 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12645 2012-03-20 Chong Yidong <cyd@gnu.org>
12647 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12648 to reflect default non-nil value of redisplay-dont-pause.
12650 2012-03-19 Kenichi Handa <handa@m17n.org>
12652 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12653 it fit in a valid range (Bug#11003).
12655 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12657 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12658 that is not from display property, accept the row as a "cursor
12659 row" if one of the string's character has a non-nil `cursor'
12660 property. Fixes cursor positioning when there are newlines in
12661 overlay strings, e.g. in icomplete.el. (Bug#11035)
12663 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12665 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12667 2012-03-12 Chong Yidong <cyd@gnu.org>
12669 * eval.c (inhibit_lisp_code): Rename from
12670 inhibit_window_configuration_change_hook; move from window.c.
12672 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12673 * window.c (run_window_configuration_change_hook)
12674 (syms_of_window): Callers changed.
12676 2012-03-11 Chong Yidong <cyd@gnu.org>
12678 * keymap.c (Fkey_description): Doc fix (Bug#9700).
12680 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12682 2012-03-10 Chong Yidong <cyd@gnu.org>
12684 * frame.c (other_visible_frames): Don't assume the selected frame
12685 is visible (Bug#10955).
12687 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12689 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
12691 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
12693 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12694 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12697 2012-03-03 Glenn Morris <rgm@gnu.org>
12699 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12701 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12703 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12704 position past the first glyph_row that ends at ZV. (Bug#10902)
12705 (redisplay_window, next_element_from_string): Fix typos in
12707 (redisplay_window): Pass to move_it_vertically the margin in
12708 pixels, not in screen lines.
12710 2012-03-02 Glenn Morris <rgm@gnu.org>
12712 * buffer.c (buffer-list-update-hook): Doc fix.
12714 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12716 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12717 push_it before setting up the iterator for the first overlay
12718 string, even if we have an empty string loaded.
12719 (next_overlay_string): If there's an empty string on the iterator
12720 stack, pop the stack. (Bug#10903)
12722 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12724 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12725 Suggested by Stefan Monnier in
12726 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12727 * alloc.c (widen_to_Lisp_Object): New static function.
12728 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12729 and widening them to Lisp_Objects. This would work even if
12730 USE_LSB_TAG is defined and wide integers are used, which might
12731 happen in a future version of Emacs.
12733 2012-02-25 Chong Yidong <cyd@gnu.org>
12735 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12738 * xselect.c (Fx_selection_exists_p): Doc fix.
12739 (x_clipboard_manager_save_all): Print an informative message
12740 before saving to clipboard manager.
12742 2012-02-24 Chong Yidong <cyd@gnu.org>
12744 * keyboard.c (process_special_events): Handle all X selection
12745 requests in kbd_buffer, not just the next one (Bug#8869).
12747 2012-02-23 Chong Yidong <cyd@gnu.org>
12749 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12750 call when setting menu-bar-lines and tool-bar-lines parameters.
12751 (unwind_create_frame_1): New helper function.
12753 * window.c (inhibit_window_configuration_change_hook): New var.
12754 (run_window_configuration_change_hook): Obey it.
12755 (syms_of_window): Initialize it.

12764 * fileio.c (Vfile_name_handler_alist): Doc fix.
12766 * buffer.c (Fget_file_buffer): Protect against invalid file
12767 handler return value.

12772 when computing $valmask.
12774 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12775 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12776 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12777 It's useless in that case, and it can cause problems on hosts
12778 that allocate halves of EMACS_INT values separately.
12779 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12780 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12781 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12782 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12783 it avoids undefined behavior on hosts where shifting right by more
12784 than the word width has undefined behavior.
12786 2012-02-19 Chong Yidong <cyd@gnu.org>
12788 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12789 (Funhandled_file_name_directory, Ffile_name_as_directory)
12790 (Fdirectory_file_name, Fexpand_file_name)
12791 (Fsubstitute_in_file_name): Protect against invalid file handler
12792 return values (Bug#10845).
12794 2012-02-18 Eli Zaretskii <eliz@gnu.org>
12796 * .gdbinit (pitx): Fix incorrect references to fields of the
12799 2012-02-17 Chong Yidong <cyd@gnu.org>

12803 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
12805 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
12806 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12808 2012-02-15 Chong Yidong <cyd@gnu.org>
12810 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12811 marked as special. Also, starting docstrings with * is obsolete.
12813 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
12815 * gnutls.c (emacs_gnutls_write): Fix last change.

12824 * keymap.c (Fsingle_key_description): Handle char ranges.
12826 2012-02-12 Chong Yidong <cyd@gnu.org>
12828 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12829 as that creates a dangerous corner case.
12831 * window.c (Fdelete_window_internal): Invalidate the mouse
12832 highlight (Bug#9904).
12834 2012-02-12 Glenn Morris <rgm@gnu.org>
12836 * xselect.c (Fx_own_selection_internal)
12837 (Fx_get_selection_internal, Fx_disown_selection_internal)
12838 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12839 * nsselect.m (Fx_own_selection_internal)
12840 (Fx_disown_selection_internal, Fx_selection_exists_p)
12841 (Fx_selection_owner_p, Fx_get_selection_internal):
12842 Sync docs and argument specs with the xselect.c versions.
12844 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12846 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
12848 2012-02-11 Eli Zaretskii <eliz@gnu.org>
12850 * w32select.c (Fx_selection_exists_p): Sync doc string and
12851 argument list with xselect.c. (Bug#10783)
12853 * w16select.c (Fx_selection_exists_p): Sync doc string and
12854 argument list with xselect.c. (Bug#10783)

13401 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13402 verifies glyph row's hash code--we have just reallocated the
13403 glyphs, so their contents can be complete garbage. (Bug#10164)

13567 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13568 is set, removing the need for VIRT_ADDRESS_VARIES.
13569 (PURE_P): Use a more-efficient implementation that needs just one
13570 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the

13572 to 4 (xorl, subq, cmpq, setbe).
13573 * alloc.c (pure): Always extern now, since that's the

13576 consistency with the new puresize.h.
13577 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13578 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13584 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13585 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13586 behave as if the cursor position were at the window margin.
13588 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13589 and the cursor position is out of bounds, behave as if the cursor
13590 position were at the window margin. (Bug#10075)
13592 2011-11-18 Chong Yidong <cyd@gnu.org>
13594 * window.c (Fwindow_combination_limit): Make first argument

13613 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13615 * xdisp.c (row_hash): New function, body extracted from
13616 compute_line_metrics.
13617 (compute_line_metrics): Call row_hash, instead of computing the
13620 * dispnew.c (verify_row_hash): Call row_hash for computing the
13621 hash code of a row, instead of duplicating code from xdisp.c.
13623 * dispextern.h (row_hash): Add prototype.
13625 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13627 * frame.c (delete_frame): Don't delete the terminal when the last

13676 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13677 with user-defined heap size. Bump the default size of the temacs

13681 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13682 current_matrix and desired_matrix. (Bug#9990)
13683 (verify_row_hash) [XASSERTS]: New function.

13730 Avoid some portability problems by eschewing 'extern inline' functions.
13731 The trivial performance wins aren't worth the portability hassles; see
13732 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13734 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

13804 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
13806 Fix some portability problems with 'inline'.
13807 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13808 (window_box_width, window_box_left, window_box_left_offset)
13809 (window_box_right, window_box_right_offset): Declare extern.
13810 Otherwise, these inline functions do not conform to C99 and
13811 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13812 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13813 * intervals.c (adjust_intervals_for_insertion)
13814 (adjust_intervals_for_deletion): Now extern, because otherwise the
13815 extern inline functions 'offset_intervals' couldn't refer to it.
13816 (static_offset_intervals): Remove.
13817 (offset_intervals): Rewrite using the old contents of
13818 static_offset_intervals. The old version didn't conform to C99
13819 because an extern inline function contained a reference to an
13820 identifier with static linkage.
13822 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
13824 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

13830 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
13831 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
13832 return Qleft_to_right.

13841 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
13842 (Fwindow_vscroll): Doc fix.
13843 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
13844 argument, since it makes no sense to pass a live window and for
13845 consistency with window-child.

13873 (unwind_create_frame): New function (Bug#9943).
13874 (Fx_create_frame): Restructure code to be more similar to the one in
13875 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
13876 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
13877 Move terminal->reference_count++ just before making the frame official
13880 * nsterm.m (x_free_frame_resources): New function.

13886 official. Move initialization of image_cache_refcount and
13887 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

13926 * xdisp.c (note_mouse_highlight): If either of
13927 previous/next-single-property-change returns nil, treat that as
13928 the beginning or the end of the buffer. (Bug#9955)
13930 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
13932 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

13955 (mouse_face_from_buffer_pos, note_mouse_highlight):
13956 Rename cover_string to disp_string.
13958 2011-11-01 Martin Rudalics <rudalics@gmx.at>
13960 * window.c (temp_output_buffer_show): Don't use
13961 Vtemp_buffer_show_specifiers.
13962 (Vtemp_buffer_show_specifiers): Remove unused variable.
13964 2011-10-30 Eli Zaretskii <eliz@gnu.org>
13966 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
13967 past the beginning of the current glyph matrix.
13969 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
13971 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
13972 (x_error_handler): Ignore BadMatch for X_SetInputFocus for

13982 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
13983 (get_current_wm_state): Return non-zero if not hidden,
13984 check for _NET_WM_STATE_HIDDEN (Bug#9893).

13992 so that this new function doesn't get optimized away by a

14015 2011-10-29 Glenn Morris <rgm@gnu.org>
14017 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14018 Not clear what it was for, and it causes various bugs. (Bug#9839)
14020 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14022 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

14024 condition to clear the mouse face.
14026 2011-10-28 Chong Yidong <cyd@gnu.org>

14042 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14044 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14045 <oslsachem@gmail.com> for helping to debug this.

14055 (w32font_open_internal, compute_metrics):
14056 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14057 instead of calling the "wide" APIs directly.
14059 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14061 * w32.h (syms_of_w32font): Add prototype.
14063 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

14067 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14068 (Fmove_to_window_line): Doc fix.
14070 2011-10-27 Chong Yidong <cyd@gnu.org>
14072 * process.c (make_process): Set gnutls_state to NULL.
14074 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14075 non-NULL, regardless of GNUTLS_INITSTAGE.
14076 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14077 an error. Set process slots as soon as we allocate them.

14103 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14105 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).

14124 (bidi_resolve_weak): Don't enter the expensive loop if the current
14125 position is before next_en_pos. Record the bidi type of the first
14126 non-ET, non-BN character we find, in addition to its position.
14127 (bidi_level_of_next_char): Invalidate next_en_type when
14128 next_en_pos is over-stepped.
14130 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14132 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14133 * editfns.c: Rewrite current-time-zone so that it invokes
14134 the equivalent of (format-time-string "%Z") to get the time zone name.
14135 This fixes a bug when the time zone name contains characters that
14136 need converting from the system time locale to Emacs internal format.
14137 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14138 that patch fixed format-time-string to do the conversion, but
14139 I forgot to fix current-time-zone.
14140 (format_time_string): New function, containing most of
14141 what Fformat_time_string used to contain.
14142 (Fformat_time_string): Rewrite in terms of format_time_string.
14143 This doesn't change this function's behavior.
14144 (current-time-zone): Rewrite to use format_time_string.
14145 This fixes the bug reported by Michael Schierl in
14146 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14147 Jason Rumney's 2007-06-07 change worked around this bug, but
14149 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14151 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14153 * xdisp.c (start_display): If the character at POS is displayed
14154 via a display vector, reset IT->current.dpvec_index to zero.
14155 (try_window_reusing_current_matrix): If a line ends in a display
14156 vector or the next line starts in a display vector, continue
14157 redrawing the window even though the character position of
14158 start_row was reached.
14161 2011-10-18 Chong Yidong <cyd@gnu.org>
14163 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14164 with nobreak-char-display too.
14166 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14168 Fix part 3 of bug#9771.
14169 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14170 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14171 non-neutral characters if the current character is a paragraph
14172 separator (a.k.a. Newline). This avoids running the same
14173 expensive loop twice, once when we consume the preceding newline
14174 and the other time when the line actually needs to be displayed.
14175 Avoid the loop when we see neutrals on the base embedding level
14176 following a character whose directionality is the same as the
14177 paragraph's. This avoids running the expensive loop when a line
14178 ends in a long sequence of neutrals, like control characters.
14179 Add assertion against STRONG_AL type. Slightly rearrange code
14180 that determines the type of a neutral given the first non-neutral
14182 (bidi_level_of_next_char): Set next_en_pos to zero when
14183 invalidating its info.
14185 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14187 * xdisp.c (push_display_prop): Determine whether to record string
14188 or buffer position by IT->string, not by IT->method. Allow
14189 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14190 (move_it_vertically_backward): Don't look for character position
14191 immediately after the newline when in a continuation line.
14194 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14196 * window.c (coordinates_in_window): Rewrite and delabelize
14197 vertical border check. (Bug#5357) (Bug#9618)
14199 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14201 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14202 errors in XSetWindowBorder (bug#9310).
14204 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14206 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14207 avoid crash when xmalloc overrun checking is enabled.
14209 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14211 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14212 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14213 cursor motion with <left> and <right> arrow keys.
14215 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14216 some callers set that themselves.
14218 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14220 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14221 display string and the previous row comes from the same string and
14222 is empty. (Bug#9739) (Bug#9738)
14224 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14226 * doc.c (get_doc_string): Encode file name (bug#9735).
14228 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14230 * bidi.c (bidi_level_of_next_char):
14231 * xdisp.c (get_visually_first_element): Remove old incorrect
14232 comments regarding the Unicode Line Separator character.
14234 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14236 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

14239 boundary if nzombies > MAX_ZOMBIES.
14240 * alloc.c (dump_zombies): Add missing format specifier.
14242 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14244 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14245 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14247 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14248 Some packages use them to denote characters with modifiers.
14250 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14252 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14253 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14254 matching a pp-number. Rename parameter var to var1.
14256 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14258 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14260 2011-10-08 Glenn Morris <rgm@gnu.org>
14262 * callint.c (Fcall_interactively): Give a more explicit error for the
14263 'c' case with a non-character input. (Bug#8479)
14265 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14267 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14269 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14270 lines that are hscrolled on the left.
14272 * dispnew.c (buffer_posn_from_coords): Account for a possible
14273 presence of header-line. (Bug#4426)
14275 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14277 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14278 Don't advertise functionality which we discourage or doesn't work.
14280 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14282 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14283 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14284 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14285 this makes Emacs dump core during garbage collection on rare
14286 occasions. sizeof is obviously inferior to offsetof here, so
14287 stick with offsetof.
14288 (GC_POINTER_ALIGNMENT): New macro.
14289 (mark_memory): Omit 3rd (offset) arg; caller changed.
14290 Don't assume EMACS_INT alignment is the same as pointer alignment.
14292 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14294 * keyboard.c (read_key_sequence_remapped): New var.
14295 (read_key_sequence): Compute remapping in the right buffer.
14296 (command_loop_1): Use read_key_sequence's remapping directly.
14298 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14300 * dired.c (file_name_completion): Don't expand file name.
14301 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14302 before checking file name handler.
14304 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14305 they've been requested explicitly (bug#9591).
14307 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14309 * keymap.c (Fsingle_key_description): Use make_specified_string
14310 instead of build_string to build string from push_key_description.
14313 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14315 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14316 This fixes a Y2038 bug on 64-bit hosts.
14317 * buffer.c (reset_buffer):
14318 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14319 (Fclear_buffer_auto_save_failure):
14320 Use 0, not -1, to represent an unset failure time, since time_t
14321 might not be signed.
14323 Remove dependency on glibc malloc internals.
14324 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14325 Move back here from lisp.h, but with their new implementations.
14326 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14327 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14328 * charset.c (charset_table_init): New static var.
14329 (syms_of_charset): Use it instead of xmalloc. This removes a
14330 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14331 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14332 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14333 Move back to alloc.c.
14334 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14335 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14337 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14339 * nsterm.m (windowDidResize): Call x_set_window_size only when
14340 ns_in_resize is true. Otherwise set pixelwidth/height and
14341 call change_frame_size (Bug#9628).
14343 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14345 Port --enable-checking=all to Fedora 14 x86-64.
14346 * charset.c (syms_of_charset): Also account for glibc malloc's
14347 internal overhead when calculating the initial malloc maximum.
14349 Port --enable-checking=all to Fedora 14 x86.
14350 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14352 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14353 (overrun_check_realloc, overrun_check_free):
14354 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14355 That way, xmalloc returns a properly-aligned pointer even if
14356 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14357 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14358 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14359 into account when calculating the initial malloc maximum.
14360 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14361 Move here from alloc.c, so that charset.c can use it too.
14362 Properly align; the old code wasn't right for common 32-bit hosts
14363 when configured with --enable-checking=all.
14364 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14365 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14367 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14369 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14372 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14374 * xdisp.c (compute_display_string_end): If there's no display
14375 string at CHARPOS, return -1.
14377 * bidi.c (bidi_fetch_char): When compute_display_string_end
14378 returns a negative value, treat the character as a normal
14379 character not covered by a display string. (Bug#9624)
14381 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14383 * lread.c (Fread_from_string): Fix typo in docstring.
14385 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14387 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14388 newline, reseat the iterator instead of bidi-iterating there one
14389 character at a time. (Bug#9610)
14390 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14391 TO_CHARPOS if the bidi iterator is at base embedding level.
14393 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14395 * lread.c (readevalloop): Use correct code for NBSP.
14396 (read1): Likewise. (Bug#9608)
14398 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14400 * dbusbind.c (Fdbus_register_signal): When service is not
14401 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14403 2011-09-25 Glenn Morris <rgm@gnu.org>
14405 * buffer.c (truncate-lines): Doc fix.
14407 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14409 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14410 (Fset_window_next_buffers): Doc fix.
14412 2011-09-24 Glenn Morris <rgm@gnu.org>
14414 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14416 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14418 Fix minor problems found by static checking.
14419 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14420 * indent.c (Fvertical_motion): Fix == vs = typo.
14422 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14424 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14425 Default value is now t. Doc fix.
14427 * indent.c (Fvertical_motion): Compute and apply the overshoot
14428 logic when moving up, not only when moving down. Fix the
14429 confusing name and values of the it_overshoot_expected variable;
14430 logic changes accordingly. (Bug#9254) (Bug#9549)
14432 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14433 CHARPOS is covered by a display string which includes newlines.
14434 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14435 is covered by a display string with embedded newlines.
14437 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14439 * dbusbind.c (Fdbus_register_signal): Add match rule to
14440 Vdbus_registered_objects_table. (Bug#9581)
14441 (Fdbus_register_method, Vdbus_registered_objects_table):
14444 2011-09-24 Jim Meyering <meyering@redhat.com>
14446 do not ignore write error for any output size
14447 The previous change was incomplete.
14448 While it makes emacs --batch detect the vast majority of stdout
14449 write failures, errors were still ignored whenever the output size is
14450 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14451 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14452 && echo FAIL: ignored write error
14453 FAIL: ignored write error
14454 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14455 && echo FAIL: ignored write error
14456 FAIL: ignored write error
14457 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14459 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14461 * emacs.c (Fkill_emacs): In noninteractive mode exit
14462 non-successfully if a write error occurred on stdout. (Bug#9574)
14464 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14466 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14469 * dispextern.h (struct it): Update the comment documenting what
14472 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14474 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14475 a display string, extend search for cursor position to end of row.
14476 (find_row_edges): If the row ends in a newline from a display
14477 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14478 Handle the case of a display string with multiple newlines.
14479 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14480 non-empty line. Fixes confusing cursor motion with arrow keys at
14481 the beginning of a line that starts with whitespace.
14483 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14485 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14488 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14490 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14491 boolean (Bug#9154).
14493 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14495 * xdisp.c (display_line): Record maximum and minimum buffer
14496 positions even if no glyphs were produced (e.g., by a zero-width
14497 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14498 buffer positions that will be removed from the glyph row because
14500 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14501 column is beyond frame width: don't subtract 1 "pixel" when
14502 computing width of the stretch.
14503 (reseat_at_next_visible_line_start): Undo the change made on
14504 2011-09-17 that saved paragraph information and restored it after
14505 the call to `reseat'. (Bug#9545)
14507 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14509 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14510 and turn window cursor on if cleared (Bug#9415).
14512 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14514 * search.c (boyer_moore): Take unibyte characters from pattern
14515 literally. (Bug#9458)
14517 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14519 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14521 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14523 Fix minor problem found by static checking.
14524 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14525 initialized, to pacify gcc -Wuninitialized.
14527 * fileio.c: Report proper errno when syscall falls.
14528 (Finsert_file_contents): Save and restore errno,
14529 so that report_file_error outputs the correct diagnostic.
14530 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14532 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14534 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14536 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14538 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14539 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14541 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14543 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14544 about the current paragraph and restore it after the call to reseat.
14546 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14547 (bidi_find_paragraph_start): Search back for paragraph beginning
14548 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14549 (bidi_move_to_visually_next): Only trigger paragraph-related
14550 computations when the last character is a newline or at EOB, not
14551 just any NEUTRAL_B. (Bug#9470)
14553 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14554 truncated lines if point is covered by a display string. (Bug#9524)
14556 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14558 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14559 (cons_to_x_long): New function.
14560 (lisp_data_to_selection_data): Use it. Correct the test for
14561 short-versus-long data; it was negated. Break out of vector
14562 loop, for efficiency, when a long datum is discovered.
14564 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14566 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14568 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14570 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14571 GCC PR/17406) by declaring this function with external scope.
14573 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14575 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14576 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14578 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14580 * editfns.c (Fformat): Correctly handle text properties on "%%".
14582 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14584 * xterm.c (x_draw_composite_glyph_string_foreground):

14586 * term.c (encode_terminal_code):
14587 * composite.c (composition_update_it, get_composition_id):
14588 * xdisp.c (get_next_display_element)
14589 (fill_composite_glyph_string): Add comments about special meaning
14590 of TAB characters in a composition.
14592 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14594 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14595 This occurs when processing a multibyte format.
14596 Problem reported by Wolfgang Jenker.
14598 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14600 * xdisp.c (try_cursor_movement): Only check for exact match if
14601 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14603 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14605 Remove unused external symbols.
14606 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14607 * xdisp.c (calc_pixel_width_or_height): Now static.
14608 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14609 * indent.c (check_display_width):
14610 * w32term.c: Fix comment to match code.
14611 * xterm.c, xterm.h (x_catching_errors): Remove.
14613 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14615 * xselect.c: Use signed conversions more consistently (Bug#9498).
14616 (selection_data_to_lisp_data): Assume incoming selection data are
14617 signed integers, not unsigned. This is to be consistent with
14618 outgoing selection data, which was modified to use signed integers
14619 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14620 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14621 expects long, not unsigned long.
14623 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14625 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14626 computation of loop end. Reported by Johan Bockgård
14629 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14631 * frame.c (Fother_visible_frames_p): Function deleted.
14633 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14635 * indent.c (compute_motion): Process display vector front to back
14636 rather than the other way around. (Bug#2496)
14638 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14640 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14642 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14644 * minibuf.c (Fread_from_minibuffer): Doc fix.
14646 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14648 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14649 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14651 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14653 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14654 value for non-existent files.
14656 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14658 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14659 set its "size" to -1. This will set the modtime_size field of
14660 the corresponding buffer to -1, which is what
14661 verify-visited-file-modtime expects for files that do not exist.
14664 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14666 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14668 * lisp.h: ... from here. push_key_description is no longer
14669 defined in keyboard.c, so its declaration should not be in
14670 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14671 logically belongs with push_key_description.
14673 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14675 * buffer.h: Include <sys/types.h> instead of <time.h>.
14676 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14677 Problem reported by Herbert J. Skuhra.
14679 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14681 * xml.c (parse_region): Make the parsing work for
14682 non-comment-starting XML files again (bug#9144).
14684 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14686 * image.c (gif_load): Fix calculation of bottom and right corner.
14689 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14691 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14692 redisplay in small windows.
14694 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14696 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14698 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14700 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14701 Operate on live windows only.
14703 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14705 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14707 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14709 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14710 only under bidi iteration.
14712 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14714 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14716 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14718 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14719 Without this fix, the command to link temacs failed due to an
14720 undefined symbol __builtin_isnan. This is because
14721 /usr/include/iso/math_c99.h #defines isnan(x) to
14722 __builtin_isnan(x), but the bundled gcc, which identifies itself
14723 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14725 * floatfns.c (isnan): #undef, and then #define to a clone of
14727 (Fisnan): Always define, since it's always available now.
14728 (syms_of_floatfns): Always define isnan at the Lisp level.
14730 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14732 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14734 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14736 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14737 The previous code assumed that file offsets (off_t values) fit in
14738 EMACS_INT variables, which is not true on typical 32-bit hosts.
14739 The code messed up by falsely reporting buffer overflow in cases
14740 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14741 when "big" contains more than 2**29 bytes, even though this
14742 inserts just one byte and does not overflow the buffer.
14743 (Finsert_file_contents): Store file offsets as off_t
14744 values, not as EMACS_INT values. Check for overflow when
14745 converting between EMACS_INT and off_t. When checking for
14746 buffer overflow or for overlap, take the offsets into account.
14747 Don't use EMACS_INT for small values where int suffices.
14748 When checking for overlap, fix a typo: ZV was used where
14749 ZV_BYTE was intended.
14750 (Fwrite_region): Don't assume off_t fits into 'long'.
14751 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14753 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14755 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14757 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14759 sprintf-related integer and memory overflow issues (Bug#9412).
14761 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14762 (esprintf, exprintf, evxprintf): New functions.
14763 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14764 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14765 (modify_event_symbol): Do not assume that the length of
14766 name_alist_or_stem is safe to alloca and fits in int.
14767 (Fexecute_extended_command): Likewise for function name and binding.
14768 (Frecursion_depth): Wrap around reliably on integer overflow.
14769 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14770 since some callers pass EMACS_INT values.
14771 (Fsingle_key_description): Don't crash if symbol name contains more
14772 than MAX_ALLOCA bytes.
14773 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14774 (get_minibuffer): Arg is now EMACS_INT, not int.
14775 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14776 (esprintf, exprintf, evxprintf): New decls.
14777 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14779 * dbusbind.c (signature_cat): New function.
14780 (xd_signature, Fdbus_register_signal):
14781 Do not overrun buffer; instead, report string overflow.
14783 * dispnew.c (add_window_display_history): Don't overrun buffer.
14784 Truncate instead; this is OK since it's just a log.
14786 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14787 even if the time zone offset is outlandishly large.
14788 Don't mishandle offset == INT_MIN.
14790 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14791 when creating daemon; the previous buffer-overflow check was incorrect.
14793 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14794 which has the guts of the old verror function.
14796 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14797 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14799 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14800 (font_unparse_xlfd): Don't blindly alloca long strings.
14801 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14802 fits in int, when using sprintf. Use single snprintf to count
14803 length of string rather than counting it via multiple sprintfs;
14804 that's simpler and more reliable.
14805 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14806 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14807 sprintf, in case result does not fit in int.
14809 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14810 (fontset_from_font): Print it.
14812 * frame.c (tty_frame_count): Now printmax_t, not int.
14813 (make_terminal_frame, set_term_frame_name): Print it.
14814 (x_report_frame_params): In X, window IDs are unsigned long,
14815 not signed long, so print them as unsigned.
14816 (validate_x_resource_name): Check for implausibly long names,
14817 and don't assume name length fits in 'int'.
14818 (x_get_resource_string): Don't blindly alloca invocation name;
14819 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14822 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14823 (xg_check_special_colors, xg_set_geometry):
14824 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14826 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14827 Use esprintf, not sprintf, in case result does not fit in int.
14829 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14830 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14831 it as a large positive number.
14832 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14833 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14835 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14836 in case result does not fit in int.
14838 * print.c (float_to_string): Detect width overflow more reliably.
14839 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14840 buffer overrun. Don't assume list length fits in 'int'. Treat
14841 print length of 0 as 0, not as infinity; to be consistent with other
14842 uses of print length in this function. Don't overflow print length
14843 index. Don't assume hash table size fits in 'long', or that
14844 vectorlike size fits in 'unsigned long'.
14846 * process.c (make_process): Use printmax_t, not int, to format
14847 process-name gensyms.
14849 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14851 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14852 to avoid potential buffer overrun.
14854 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14855 if X resource line is longer than 512 bytes.
14857 * xfns.c (x_window): Make sprintf buffer a bit bigger
14858 to avoid potential buffer overrun.
14860 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14862 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14864 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14866 Integer overflow fixes for scrolling, etc.
14867 Without these, Emacs silently mishandles large integers sometimes.
14868 For example, "C-u 4294967297 M-x recenter" was treated as if
14869 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14871 * xdisp.c (try_window_id): Check Emacs fixnum range before
14872 converting to 'int'.
14874 * window.c (window_scroll_line_based, Frecenter):
14875 Check that an Emacs fixnum is in range before assigning it to 'int'.
14876 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14877 values converted from Emacs fixnums.
14878 (Frecenter): Don't wrap around a line count if it is out of 'int'
14879 range; instead, treat it as an extreme value.
14880 (Fset_window_configuration, compare_window_configurations):
14881 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14883 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14884 that can exceed INT_MAX. Check that EMACS_INT value is in range
14885 before assigning it to the (possibly-narrower) index.
14886 (match_limit): Don't assume that a fixnum can fit in 'int'.
14888 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14891 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14892 (Fvertical_motion): Don't wrap around LINES values that don't fit
14893 in 'int'. Instead, treat them as extreme values. This is good
14894 enough for windows, which can't have more than INT_MAX lines anyway.
14896 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14898 * Require libxml/parser.h to avoid compilation warning.
14900 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14902 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14903 since this reportedly can destroy thread storage.
14905 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14907 * syntax.c (find_defun_start): Update all cache variables if
14908 exiting early (Bug#9401).
14910 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14912 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14914 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14915 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14916 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14918 * term.c (tty_append_glyph): New function.
14919 (produce_stretch_glyph): Static function and its prototype deleted.
14921 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14924 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14926 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14927 when checking :margin (Bug#9390).
14928 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14929 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14930 so that the name doesn't mislead. All uses changed.
14932 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14934 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14937 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14939 * xdisp.c (move_it_to): Don't bail out early when reaching
14940 position beyond to_charpos, if we are scanning backwards.
14941 (move_it_vertically_backward): When DY == 0, make sure we get to
14942 the first character in the line after the newline.
14944 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14946 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14947 (ccl_driver): Do not generate an out-of-range pointer.
14948 (Fccl_execute_on_string): Remove unnecessary check for
14949 integer overflow, noted by Stefan Monnier in
14950 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14951 Remove a FIXME that didn't need fixing.
14952 Simplify the newly-introduced buffer reallocation code.
14954 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14956 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14958 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14960 Integer and memory overflow issues (Bug#9196).
14962 * doc.c (get_doc_string): Rework so that
14963 get_doc_string_buffer_size is the actual buffer size, rather than
14964 being 1 less than the actual buffer size; this makes xpalloc more
14967 * image.c (x_allocate_bitmap_record, cache_image):
14968 * xselect.c (Fx_register_dnd_atom):
14969 Simplify previous changes by using xpalloc.
14971 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14972 since either will do and ptrdiff_t is convenient with xpalloc.
14974 * charset.c (charset_table_size)
14975 (struct charset_sort_data.priority): Now ptrdiff_t.
14976 (charset_compare): Don't overflow if priorities differ greatly.
14977 (Fsort_charsets): Don't assume list length fits in int.
14978 Check for size-calculation overflow when allocating sort data.
14979 (syms_of_charset): Allocate an initial charset table that is
14980 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14982 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14984 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14985 The actual value is always <= INT_MAX, and leaving it unsigned made
14986 overflow checking harder.
14988 * dispextern.h (struct glyph_matrix.rows_allocated)
14989 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14990 with xpalloc. The values are still always <= INT_MAX.
14992 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14994 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14995 (SAFE_NALLOCA): New macro.
14997 * region-cache.c (struct boundary.pos, find_cache_boundary)
14998 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14999 (set_cache_region, invalidate_region_cache)
15000 (revalidate_region_cache, know_region_cache, region_cache_forward)
15001 (region_cache_backward, pp_cache):
15002 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15003 so that ptrdiff_t * can be passed to xpalloc.
15004 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15005 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15006 (pp_cache): Don't assume cache_len fits in int.
15007 * region-cache.h: Adjust extern decls to match.
15009 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15010 EMACS_INT, since either will do, for xpalloc.
15012 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15013 (xnmalloc, xnrealloc, xpalloc): New functions.
15015 * bidi.c (bidi_shelve_header_size): New constant.
15016 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15017 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15019 * bidi.c (bidi_cache_shrink):
15020 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15022 Don't update size of array until after memory allocation succeeds,
15023 because xmalloc/xrealloc may not return.
15024 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15025 now that we have proper integer overflow checking.
15026 (record_overlay_string, overlay_strings): Catch overflows when
15027 calculating size of overlay_str_buf.
15029 * callproc.c (Fcall_process): Check for size overflow when
15030 calculating size of args2.
15031 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15032 Normally we prefer signed values, but sticking with ptrdiff_t would
15033 require adding more-complicated checks.
15035 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15036 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15037 Redo buffer-overflow calculations to avoid integer overflow.
15038 Add a FIXME comment where memory seems to be over-allocated.
15040 * character.c (Fstring): Check for size-calculation overflow.
15042 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15043 unnecessary integer overflow. Check for size overflow.
15044 (encode_coding_object): Don't update size until xmalloc succeeds.
15046 * composite.c (get_composition_id): Check for overflow in glyph
15047 length calculations.
15049 Integer and memory overflow fixes for display code.
15050 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15051 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15052 (scrolling_window): Check for overflow in size calculations.
15053 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15054 Don't assume glyph table len fits in int.

15056 (row_table_size): Now ptrdiff_t, not int.
15057 (scrolling_window): Avoid overflow in size calculations.
15058 Don't update size until allocation succeeds.
15059 * fns.c (concat): Check for overflow in size calculations.
15060 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15061 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15062 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15064 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15065 (get_doc_string): Check for size calculation overflow.
15066 Don't update size until allocation succeeds.
15067 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15068 EMACS_INT, where ptrdiff_t will do.
15069 (Fsubstitute_command_keys): Check for string overflow.
15071 * editfns.c (set_time_zone_rule): Don't assume environment length
15073 (message_length): Now ptrdiff_t, not int.
15074 (Fmessage_box): Don't update size until allocation succeeds.
15075 Don't assume message length fits in int.
15076 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15078 * emacs.c (main): Do not reallocate argv, since there is a null at
15079 the end that can be overwritten, and this way there's no need to
15080 worry about size-calculation overflow.
15081 (sort_args): Check for size-calculation overflow.
15083 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15085 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15087 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15088 (x_set_scroll_bar_width, x_figure_window_size):
15089 Check for integer overflow.
15090 (x_set_alpha): Do not assume XINT fits in int.
15092 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15093 This is for the members text_lines, text_cols, total_lines, total_cols,
15094 where the system imposes an 'int' limit.
15096 * fringe.c (Fdefine_fringe_bitmap):
15097 Don't update size until alloc works.
15099 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15100 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15102 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15103 Check for size-calculation overflow.
15104 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15105 do, as we prefer signed integers.
15106 (id_to_widget.max_size, id_to_widget.used)
15107 (xg_store_widget_in_map, xg_remove_widget_from_map)
15108 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15109 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15110 Use and return ptrdiff_t, not int.
15111 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15112 * gtkutil.h: Change prototypes to match the above.
15114 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15115 are duplicate now that they've been promoted to lisp.h.
15116 (x_allocate_bitmap_record, x_alloc_image_color)
15117 (make_image_cache, cache_image, xpm_load):
15118 Don't update size until alloc is done.
15119 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15121 Check for size calculation overflow.
15122 (ct_colors_allocated_max): New constant.
15123 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15126 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15127 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15128 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15129 Use ptrdiff_t, not int, to count maps.
15130 (read_char_minibuf_menu_prompt): Check for overflow in size
15131 calculations. Don't update size until allocation succeeds.
15132 Redo calculations to avoid overflow.
15133 * keyboard.h: Change prototypes to match the above.
15135 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15137 (current_minor_maps): Check for size calculation overflow.
15138 * keymap.h: Change prototypes to match the above.
15140 * lread.c (read1, init_obarray): Don't update size until alloc done.
15142 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15143 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15145 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15146 Now ptrdiff_t, not int.
15147 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
15148 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
15150 * process.c (Fnetwork_interface_list): Check for overflow
15151 in size calculation.
15153 * region-cache.c (move_cache_gap): Check for size calculation overflow.
15155 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
15156 overflow. Don't bother calling xmalloc when xrealloc will do.
15158 * search.c (Freplace_match): Check for size calculation overflow.
15159 (Fset_match_data): Don't assume list lengths fit in 'int'.
15161 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15162 for command line length. Do not attempt to address one before the
15163 beginning of an array, as that's not portable.
15165 * term.c (max_frame_lines): Remove; unused.
15166 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15168 (encode_terminal_code, calculate_costs): Check for size
15169 calculation overflow.

15172 done. Redo calculations to avoid overflow.
15173 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15175 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15176 subtracting pointers.
15177 (gobble_line): Check for overflow more carefully. Don't update size
15180 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
15181 Don't update size until alloc done.
15182 Redo size calculations to avoid overflow.
15183 Check for size calculation overflow.
15184 (main) [DEBUG]: Fix typo in invoking tparam1.

15191 Use ptrdiff_t, not int, for sizes.
15192 (Finternal_make_lisp_face, cache_face):
15193 Check for size calculation overflow.
15194 (cache_face): Treat size calculation overflows as if they were
15195 memory exhaustion (the usual treatment), rather than aborting.
15197 * xfns.c (x_encode_text, x_set_name_internal)
15198 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15199 sizes, since they can exceed INT_MAX in size. Check for size
15200 calculation overflow.
15202 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15203 (xg_select): Check for size calculation overflow.
15204 Don't update size until alloc done.
15206 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15207 as sprintf is limited to int lengths.
15209 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15210 (X_LONG_MIN): New macros.
15211 Use them to make the following changes clearer.
15212 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15213 This change doesn't affect the value now, but it may help remind
15214 future maintainers not to raise the value too much later.
15215 (SELECTION_QUANTUM): Remove, replacing with ...
15216 (selection_quantum): ... new function, which avoids overflow.
15218 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15219 assumption that selection length fits in 'int'.
15220 (x_reply_selection_request, x_handle_selection_request)
15221 (x_get_window_property, receive_incremental_selection)
15222 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15223 (lisp_data_to_selection_data, clean_local_selection_data):

15225 (x_reply_selection_request, x_get_window_property)
15226 (receive_incremental_selection, x_property_data_to_lisp):
15227 Redo calculations to avoid overflow.
15228 (x_reply_selection_request): When sending hint, ceiling it at
15229 X_LONG_MAX rather than relying on wraparound overflow to send
15231 (x_get_window_property, receive_incremental_selection)
15232 (lisp_data_to_selection_data, x_property_data_to_lisp):
15233 Check for size-calculation overflow.
15234 (x_get_window_property, receive_incremental_selection)

15236 Don't store size until memory allocation succeeds.
15237 (x_get_window_property): Plug memory leak on memory exhaustion.
15238 Don't double-block input; malloc is safe here. Don't assume 2**34
15239 - 4 fits in unsigned long. Add an xassert to check
15240 XGetWindowProperty overflow. Be more careful about overflow
15241 calculations, and distinguish size from memory overflow better.
15242 (receive_incremental_selection): When tracing, don't assume
15243 unsigned int is less than INT_MAX.
15244 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15245 harmful) conversions of unsigned short to int.
15246 (lisp_data_to_selection_data): Don't assume that integers
15247 in the range -65535 through -1 fit in an X unsigned short.
15248 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15249 result parameters unless successful. Rely on cons_to_unsigned
15250 to report problems with elements; the old code wasn't right anyway.
15251 (x_check_property_data): Check for int overflow; we cannot use
15252 a wider type due to X limits.
15253 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15255 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15257 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15258 (x_term_init): Check for size calculation overflow.
15259 (x_color_cells): Don't store size until memory allocation succeeds.
15260 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15261 Don't assume alloca size is less than MAX_ALLOCA.
15262 (x_term_init): Don't assume length fits in int (sprintf is limited
15265 Use ptrdiff_t for composition IDs.

15284 * image.c (xpm_get_color_table_h):
15285 * lisp.h (hash_lookup, hash_put):
15286 * minibuf.c (Ftest_completion):
15287 Use ptrdiff_t for hash table indexes, not int (which is too
15288 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15289 32-bit --with-wide-int hosts).
15291 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15292 Add a FIXME comment about memory leaks.
15293 (syms_of_charset): Don't assume xmalloc returns.

15300 with outlandish widths.
15301 * character.h (sanitize_tab_width): Rename from sanitize_width,
15302 now that we have two such functions. All uses changed.

15314 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15316 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

15320 * xterm.c: Don't go over XClientMessageEvent limit.
15321 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15322 (x_send_scroll_bar_event): Likewise. Check that the size does not
15323 exceed limits imposed by XClientMessageEvent, as well as the usual
15324 ptrdiff_t and size_t limits.
15326 * keyboard.c: Overflow, signedness and related fixes.
15327 (make_lispy_movement): Use same integer type in forward decl
15328 that is used in the definition.
15329 (read_key_sequence, keyremap_step):
15330 Change bufsize argument back to int, undoing my 2011-03-30 change.
15331 We prefer signed types, and int is wide enough here.
15332 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15333 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15334 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15335 length, not size_t. Use ptrdiff_t for index, not int.
15336 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15337 possibility of integer overflow.
15339 Overflow, signedness and related fixes for images.
15341 * dispextern.h (struct it.stack[0].u.image.image_id)

15349 * xdisp.c (calc_pixel_width_or_height):
15350 * xfns.c (image_cache_refcount):

15360 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15361 (lookup_image): Remove unnecessary tests.
15362 (xbm_image_p): Locals are now of int, not EMACS_INT,
15363 since parse_image_check makes sure they fit into int.
15364 (png_load, gif_load, svg_load_image):
15365 Prefer int to unsigned where either will do.
15366 (tiff_handler): New function, combining the cores of the
15367 old tiff_error_handler and tiff_warning_handler.
15368 This function is rewritten to use vsnprintf and thereby avoid
15369 stack buffer overflows. It uses only the features of vsnprintf
15370 that are common to both POSIX and native Microsoft.
15371 (tiff_error_handler, tiff_warning_handler): Use it.
15372 (tiff_load, gif_load, imagemagick_load_image):
15373 Don't assume :index value fits in 'int'.
15374 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15375 (imagemagick_load_image): Check that crop parameters fit into
15376 the integer types that MagickCropImage accepts. Don't assume
15377 Vimagemagick_render_type has a nonnegative value. Don't assume
15378 size_t fits in 'long'.
15379 (gs_load): Use printmax_t to print the widest integers possible.
15380 Check for integer overflow when computing image height and width.
15382 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15384 * xdisp.c (redisplay_window): Don't force window start if point

15390 the display spec is of the form `(space ...)'.
15391 (handle_display_spec): Return the value returned by
15392 handle_single_display_spec, not just 1 or zero.
15393 (handle_single_display_spec): If the display spec is of the form
15394 `(space ...)', and specifies display in the text area, return 2
15396 (try_cursor_movement): Check for the need to scroll more
15397 accurately, and prefer exact match for point under bidi.
15398 Don't advance `row' beyond the last row of the window.
15400 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15401 into disp_prop; all users changed.

15415 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15416 buffers, return left-to-right.
15417 (set_cursor_from_row): Consider candidate row a win if its glyph
15418 represents a newline and point is on that newline. Fixes cursor
15419 positioning on the newline at EOL of R2L text within L2R
15420 paragraph, and vice versa.
15421 (try_cursor_movement): Check continued rows, in addition to
15422 continuation rows. Fixes unwarranted scroll when point enters a
15423 continued line of R2L text within an L2R paragraph, or vice versa.
15424 (cursor_row_p): Consider the case of point being equal to
15425 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15426 from the end of a short line to the beginning of a continued line
15427 of R2L text within L2R paragraph.
15428 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15429 composed characters.

15454 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15455 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15456 candidate is selected by the mouse, and that candidate has a
15457 composed character under the mouse.
15459 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15460 coordinates reported by pos-visible-in-window-p for a composed
15461 character in column zero.
15463 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15467 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15469 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15470 consider it a hit if to_charpos is anywhere in the range of the
15471 composed buffer positions.
15473 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15475 * image.c (gif_load): Don't assume that each subimage has the same
15476 dimensions as the base image. Handle disposal method that is
15477 "undefined" by the gif spec (Bug#9335).
15479 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15481 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15487 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15488 from an Org mode buffer to a Speedbar frame.
15490 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15491 a composition, take its buffer position from IT->cmp_it.charpos.
15492 Fixes cursor positioning at the beginning of a line that begins
15493 with a composed character.
15495 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15497 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15498 character bidirectional type, use STRONG_L instead. Fixes crashes
15499 in a buffer produced by `describe-categories'.
15501 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15502 members before the level stack, so they would be saved and
15503 restored when copying iterator state. Fixes incorrect reordering
15504 around TABs covered by display properties.
15506 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

15532 Fix memory allocation problems in Cygwin build (Bug#9273).
15534 * unexcw.c ( __malloc_initialized): Declare external variable.
15535 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15537 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15539 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

15578 * xdisp.c (move_it_in_display_line_to): Don't invoke
15579 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15580 ppos_it. Fixes vertical cursor motion when line beginning is
15581 covered by an image. (Bug#9296)
15583 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15585 * nsterm.h (ns_run_ascript): Declare.

15591 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15592 the event loop. Get status from as_status (Bug#7276).
15594 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15595 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15596 the event loop (Bug#7276).

15600 * gnutls.c (QCgnutls_bootprop_priority)
15601 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
15602 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
15603 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
15604 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
15605 (QCgnutls_bootprop_verify_hostname_error)
15606 (QCgnutls_bootprop_callbacks_verify): Rename from
15607 Qgnutls_bootprop_..., all uses changed.
15609 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
15612 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
15614 * xfaces.c (Qframe_set_background_mode): Now static.
15615 * dispextern.h (Qframe_set_background_mode): Remove decl.
15617 * process.c (Fnetwork_interface_info): Declare local only if needed.
15619 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
15621 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15622 (Fnetwork_interface_list): Allocate in increments of bytes instead
15623 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15624 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15626 (struct ifflag_def): notrailers is smart on OSX.
15627 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15628 Get hardware address with getifaddrs if available.
15630 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15632 * xdisp.c (iterate_out_of_display_property): xassert that
15633 IT->position is set to within IT->object's boundaries. Break from
15634 the loop as soon as EOB is reached; avoids infloops in redisplay
15635 when IT->position is set up wrongly due to some bug.
15636 Set IT->current to match the bidi iterator unconditionally.
15637 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15638 entry. Force push_it to save on the stack the current
15639 buffer/string position, to be restored by pop_it. Fix flags in
15640 the iterator structure wrt the object coming from a display
15641 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15642 properties. (Bug#9284)
15644 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15646 * fontset.c (fontset_get_font_group): Add proper type checks.
15649 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15651 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
15652 and LC_VERSION_MIN_MACOSX.
15653 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
15654 (dump_it) [LC_FUNCTION_STARTS]: Use it.
15656 2011-08-08 Eli Zaretskii <eliz@gnu.org>
15658 * xdisp.c (forward_to_next_line_start): Allow to use the
15659 no-display-properties-and-no-overlays under bidi display.
15660 Set disp_pos in the bidi iterator to avoid searches for display
15661 properties and overlays.
15663 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15665 * editfns.c (Fset_time_zone_rule): Document relationship with the
15668 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
15669 the font entity extracted from the cache (Bug#8109).
15671 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15673 * composite.c (autocmp_chars): Don't reset point. That is done by
15674 restore_point_unwind (Bug#5984).
15676 2011-08-07 Juri Linkov <juri@jurta.org>
15678 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15679 to show the arg `TIME' instead of `TIMEVAL'.
15681 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15683 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15684 display property strides EOL and includes a newline, as in
15685 longlines-mode. (Bug#9254)
15686 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15687 word-wrap under bidirectional display. (Bug#9224)
15689 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15690 is non-zero, even if the data buffer is NULL. Fixes a crash in
15691 vertical-motion with longlines-mode. (Bug#9254)
15693 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15695 * bidi.c <bidi_cache_total_alloc>: Now static.
15696 (bidi_initialize): Initialize bidi_cache_total_alloc.
15698 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15701 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15702 amount allocated this far in `bidi_cache_total_alloc'.
15703 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15704 non-zero, only free the data buffer without restoring the cache
15705 contents. All callers changed.
15707 * dispextern.h (bidi_unshelve_cache): Update prototype.
15709 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15710 (move_it_in_display_line, move_it_to)
15711 (move_it_vertically_backward, move_it_by_lines): Replace the call
15712 to xfree to an equivalent call to bidi_unshelve_cache.
15713 (move_it_in_display_line_to): Fix logic of returning
15714 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15716 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15718 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15719 came from a string character with a `cursor' property. (Bug#9229)
15721 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15723 * Makefile.in (LIB_PTHREAD): New variable.
15724 (LIBES): Add LIB_PTHREAD (Bug#9216).
15726 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15727 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15729 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15731 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15733 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15735 * xterm.c (x_find_topmost_parent): New function.
15736 (x_set_frame_alpha): Find topmost parent window with
15737 x_find_topmost_parent and set the property there also (bug#9181).
15738 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15740 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15742 * callproc.c (Fcall_process): Avoid vfork clobbering
15743 the local vars buffer, coding_systems, current_dir.
15745 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15747 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15749 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15751 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15752 so that it is not optimized away.
15754 * xdisp.c (compute_display_string_pos): Remove unused local.
15756 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15758 Fix slow cursor motion and scrolling in large buffers with
15759 selective display, like Org Mode buffers. (Bug#9218)
15761 * dispextern.h (struct bidi_it): New member disp_prop_p.
15763 * xdisp.c: Remove one-slot cache of display string positions.
15764 (compute_display_string_pos): Accept an additional argument
15765 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15766 for a display string or property. If found, set DISP_PROP_P
15769 * bidi.c (bidi_fetch_char): Accept an additional argument
15770 DISP_PROP_P, and pass it to compute_display_string_pos.
15771 Only handle text covered by a display string if DISP_PROP_P is returned
15772 non-zero. All callers of bidi_fetch_char changed.
15774 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15776 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15778 2010-12-03 Don March <don@ohspite.net>
15780 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15781 last character M-[char] is translated to ESC [char] (bug#7541).
15783 2011-08-02 Kenichi Handa <handa@m17n.org>
15785 * lisp.h (uniprop_table): Extern it.
15787 * chartab.c (uniprop_table): Make it non-static.
15789 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15791 * xdisp.c (forward_to_next_line_start): Accept additional argument
15792 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15794 (reseat_at_next_visible_line_start): Use the bidi iterator state
15795 returned by forward_to_next_line_start to restore the state of
15796 it->bidi_it after backing up to previous newline. (Bug#9212)
15798 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15800 * regex.c (re_comp): Protoize.
15801 (re_exec): Fix return type.
15802 (regexec): Fix type of `ret'. (Bug#9203)
15804 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15806 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15807 This is needed if max-image-size is a floating-point number.
15809 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15811 * print.c (print_object): Print empty symbol as ##.
15813 * lread.c (read1): Read ## as empty symbol.
15815 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15817 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15818 setting frame foreground color (Bug#9175).
15819 (x_set_background_color): Likewise.
15821 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15822 contents (Bug#9176).
15823 (EmacsTooltip -init): Remove bezels and add shadows to
15826 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15827 or scroll bar (Bug#8470).
15829 * nsfont.m (nsfont_open): Remove assignment to voffset and
15830 unnecessary vars hshink, expand, hd, full_height, min_height.
15831 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15833 * nsterm.h (nsfont_info): Remove voffset field.
15835 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15837 Implement strike-through and overline on NextStep (Bug#8863).
15839 * nsfont.m (nsfont_open): Use underline position provided by font,
15840 instead of hard-coded value of 2.
15841 (nsfont_draw): Call ns_draw_text_decoration instead.
15843 * nsterm.h: Add declaration for ns_draw_text_decoration.
15845 * nsterm.m (ns_draw_text_decoration): New function for drawing
15846 underline, overline, and strike-through.
15847 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15848 ns_draw_text_decoration. Change treatment of cursor drawing to
15849 accommodate underlining, etc.
15851 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15853 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15856 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15858 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15859 Without this fix, if a signal arrives just after memory fills up,
15860 'malloc' might be invoked reentrantly.
15862 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15863 In other words, assume that every image size is allowed, on non-X
15864 hosts. This assumption is probably wrong, but it lets Emacs compile.
15866 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15868 * regex.c (re_iswctype): Convert return values to boolean.
15870 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15872 * xdisp.c (compute_display_string_pos): Don't use cached display
15873 string position if the buffer had its restriction changed.
15876 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15878 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15880 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15882 Integer signedness and overflow and related fixes. (Bug#9079)
15884 * bidi.c: Integer size and overflow fixes.
15885 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15886 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15887 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15888 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15889 (bidi_find_other_level_edge):
15890 Use ptrdiff_t instead of EMACS_INT where either will do.
15891 This works better on 32-bit hosts configured --with-wide-int.
15892 (bidi_cache_ensure_space): Check for size-calculation overflow.
15893 Use % rather than repeated addition, for better worst-case speed.
15894 Don't set bidi_cache_size until after xrealloc returns, because it
15896 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15897 (bidi_cache_ensure_space): Also check that the bidi cache size
15898 does not exceed that of the largest Lisp string or buffer. See Eli
15899 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15901 * alloc.c (__malloc_size_t): Remove.
15902 All uses replaced by size_t. See Andreas Schwab's note
15903 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15905 * image.c: Improve checking for integer overflow.
15906 (check_image_size): Assume that f is nonnull, since
15907 it is always nonnull in practice. This is one less thing to
15908 worry about when checking for integer overflow later.
15909 (x_check_image_size): New function, which checks for integer
15910 overflow issues inside X.
15911 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15912 This removes the need for a memory_full check.
15913 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15914 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15915 (xbm_read_bitmap_data): Change locals back to 'int', since
15916 their values must fit in 'int'.
15917 (xpm_load_image, png_load, tiff_load):
15918 Invoke x_create_x_image_and_pixmap earlier,
15919 to avoid much needless work if the image is too large.
15920 (tiff_load): Treat overly large images as if
15921 x_create_x_image_and_pixmap failed, not as malloc failures.
15922 (gs_load): Use x_check_image_size.
15924 * gtkutil.c: Omit integer casts.
15925 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15926 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15928 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15930 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15931 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15932 would wrongly return t on a 64-bit host.
15934 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15935 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15936 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15937 and therefore cause GCC to emit a bogus diagnostic in some cases.
15939 * image.c: Integer signedness and overflow and related fixes.
15940 This is not an exhaustive set of fixes, but it's time to
15941 record what I've got.
15942 (lookup_pixel_color, check_image_size): Remove redundant decls.
15943 (check_image_size): Don't assume that arbitrary EMACS_INT values
15944 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15945 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15946 (tiff_load, imagemagick_load_image):
15947 Check for overflow in size calculations.
15948 (x_create_x_image_and_pixmap): Remove unnecessary test for
15949 xmalloc returning NULL; that can't happen.
15950 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15951 (xpm_color_bucket): Use better integer hashing function.
15952 (xpm_cache_color): Don't possibly over-allocate memory.
15953 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15954 (gif_memory_source):
15955 Use ptrdiff_t, not int or size_t, to record sizes.
15956 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15957 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15958 either works, as we prefer signed integers.
15959 (tiff_read_from_memory, tiff_write_from_memory):
15960 Return tsize_t, not size_t, since that's what the TIFF API wants.
15961 (tiff_read_from_memory): Don't fail simply because the read would
15962 go past EOF; instead, return a short read.
15963 (tiff_load): Omit no-longer-needed casts.
15964 (Fimagemagick_types): Don't assume size fits into 'int'.
15966 Improve hashing quality when configured --with-wide-int.
15967 * fns.c (hash_string): New function, taken from sxhash_string.
15968 Do not discard information about ASCII character case; this
15969 discarding is no longer needed.
15970 (sxhash-string): Use it. Change sig to match it. Caller changed.
15971 * lisp.h: Declare it.
15972 * lread.c (hash_string): Remove, since we now use fns.c's version.
15973 The fns.c version returns a wider integer if --with-wide-int is
15974 specified, so this should help the quality of the hashing a bit.
15976 * emacs.c: Integer overflow minor fix.
15977 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15978 Define only if GNU_LINUX.
15979 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15981 * dispnew.c: Integer signedness and overflow fixes.
15982 Remove unnecessary forward decls, that were a maintenance hassle.
15983 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15985 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15986 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15987 (prepare_desired_row, line_draw_cost):
15988 Use int, not unsigned, where either works.
15989 (save_current_matrix, restore_current_matrix):
15990 Use ptrdiff_t, not size_t, where either works.
15991 (init_display): Check for overflow more accurately, and without
15992 relying on undefined behavior.
15994 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15995 Remove, replacing with the new symbols in lisp.h. All uses changed.
15996 * fileio.c (make_temp_name):
15997 * filelock.c (lock_file_1, lock_file):
15998 * xdisp.c (message_dolog):
15999 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16000 Use pMd etc. instead.
16001 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16002 replacing the pWIDE etc. symbols removed from editfns.c.
16004 * keyboard.h (num_input_events): Now uintmax_t.
16005 This is (very slightly) less likely to mess up due to wraparound.
16008 * buffer.c: Integer signedness fixes.
16009 (alloc_buffer_text, enlarge_buffer_text):
16010 Use ptrdiff_t rather than size_t when either will do, as we prefer
16013 * alloc.c: Integer signedness and overflow fixes.
16014 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16015 (__malloc_size_t): Default to size_t, not to int.
16016 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16017 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16018 Prefer ptrdiff_t to size_t when either would do, as we prefer
16020 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16021 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16022 Now const. Initialize with values that are in range even if char
16024 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16025 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16026 These functions do the right thing with sizes > 2**32.
16027 (check_depth): Now ptrdiff_t, not int.
16028 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16029 Adjust to new way of storing sizes. Check for size overflow bugs
16031 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16032 slightly wrong anyway, as it missed one instance of
16033 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16034 (refill_memory_reserve): Omit needless cast to size_t.
16035 (mark_object_loop_halt): Mark as externally visible.
16037 * xselect.c: Integer signedness and overflow fixes.
16038 (Fx_register_dnd_atom, x_handle_dnd_message):
16039 Use ptrdiff_t, not size_t, since we prefer signed.
16040 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16041 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16042 x_dnd_atoms_size and x_dnd_atoms_length.
16044 * doprnt.c: Prefer signed to unsigned when either works.
16046 * doprnt.c (doprnt):
16048 * xdisp.c (vmessage):
16049 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16050 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16051 prefer signed arithmetic to avoid comparison confusion.
16052 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16053 but is a bit tricky.
16055 Assume freestanding C89 headers, string.h, stdlib.h.
16056 * data.c, doprnt.c, floatfns.c, print.c:
16057 Include float.h unconditionally.
16058 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16059 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16060 * regex.c: Likewise for stddef.h, string.h.
16061 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16062 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16063 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16064 (STDC_HEADERS): Remove obsolete defines.
16065 * sysdep.c: Include limits.h unconditionally.
16067 Assume support for memcmp, memcpy, memmove, memset.
16068 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16069 * regex.c (memcmp, memcpy):
16070 Remove; we assume C89 now.
16072 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16073 (__malloc_safe_bcopy): Remove; no longer needed.
16075 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16076 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16077 well either way, and we prefer signed to unsigned.
16079 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16081 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16082 closes the connection while we're reading (bug#9182).
16084 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16086 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16087 are specified (Bug#9168).
16089 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16091 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16092 Found by GCC static checking and --with-wide-int on a 32-bit host.
16094 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16096 * xdisp.c (compute_display_string_pos): Fix logic of caching
16097 previous display string position. Initialize cached_prev_pos to
16098 -1. Fixes slow-down at the beginning of a buffer.
16100 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16102 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16103 for attrs[LFACE_FONTSET_INDEX].
16105 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16107 * xml.c (parse_region): Remove unused local
16108 that was recently introduced.
16110 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16112 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16113 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16115 * xdisp.c (move_it_in_display_line_to): Record the best matching
16116 position for TO_CHARPOS while scanning the line, and restore it on
16117 exit if none of the characters scanned was an exact match.
16118 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16119 when exact match is impossible due to invisible text, and the
16120 lines are truncated.
16122 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16124 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16127 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16129 Fix a significant slow-down of cursor motion with C-n, C-p,
16130 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16131 auto-repeat under bidi redisplay in fontified buffers.
16132 * xdisp.c (compute_stop_pos_backwards): New function.
16133 (next_element_from_buffer): Call compute_stop_pos_backwards to
16134 find a suitable prev_stop when we find ourselves before
16136 (reseat): Don't look for prev_stop, as that could mean a very long
16138 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16139 <cached_disp_overlay_modiff>: Cache for last found display string
16141 (compute_display_string_pos): Return the cached position if asked
16142 about the same buffer in the same area of character positions, and
16143 the buffer wasn't changed since the time the display string
16144 position was cached.
16146 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16148 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16149 is an integer, which is important for empty lines. (Bug#9149)
16151 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16153 * frame.c (Fmodify_frame_parameters): In tty case, update the
16154 default face if necessary (Bug#4238).
16156 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16158 * editfns.c (Fstring_to_char): No need to explain what a character
16159 is in the docstring (Bug#6576).
16161 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16163 * xml.c (parse_region): Make sure we always return a tree.
16165 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16167 * xml.c (parse_region): If a document contains only comments,
16170 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16172 * xml.c (make_dom): Return comments, too.
16174 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16177 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16178 and the surrounding thread.
16179 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16180 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16181 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16183 * s/openbsd.h (BROKEN_SIGIO): Define.
16184 * unexelf.c (unexec) [__OpenBSD__]:
16185 Don't update the .mdebug section of the Alpha COFF symbol table.
16187 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16189 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16192 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16194 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16195 This fixes some race conditions on the permissions of any newly
16198 * alloc.c (valid_pointer_p): Use pipe, not open.
16199 This fixes some permissions issues when debugging.
16201 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16202 If fchown fails to set both uid and gid, try to set just gid,
16203 as that is sometimes allowed. Adjust the file's mode to eliminate
16204 setuid or setgid bits that are inappropriate if fchown fails.
16206 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16208 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16209 to compare Lisp_Objects.
16210 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16211 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16212 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16214 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16216 * lread.c (read_integer): Unread even EOF character.
16217 (read1): Likewise. Properly record start position of symbol.
16219 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16220 symbol character follows.
16222 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16224 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16225 This works around a problem with the previous change to Fcopy_file.
16226 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16227 and without this change, GCC might complain about discarding
16228 fchown's return value.
16230 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16232 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16234 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16236 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16238 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16240 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16241 it's used from the C level.
16243 * process.c: Use the same condition for POLL_FOR_INPUT in both
16244 keyboard.c and process.c (bug#1858).
16246 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16248 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16249 (Fgnutls_boot): Use it.
16251 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16253 * doc.c (Fsubstitute_command_keys): Revert last change.
16255 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16257 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16258 quotes the next character, and doesn't affect other longer
16259 sequences (bug#8935).
16261 * lread.c (syms_of_lread): Clarify that is isn't only
16262 `eval-buffer' and `eval-defun' that's affected by
16263 `lexical-binding' (bug#8460).
16265 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16267 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16268 bidi redisplay when a line includes both an image and is truncated.
16270 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16272 Fix minor problems found by static checking.
16273 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16274 (elsz): Now a signed constant, not a size_t var. We prefer signed
16275 types to unsigned, to avoid integer comparison confusion. Without
16276 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16277 "cannot optimize loop, the loop counter may overflow", a symptom
16279 * indent.c (Fvertical_motion): Mark locals as initialized.
16280 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16282 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16284 * search.c (Fre_search_backward): Mention `case-fold-search' in
16285 all the re_search_* functions (bug#8138).
16287 * keyboard.c (Fopen_dribble_file): Document when the file is

16298 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
16299 (reseat_to_string): Initialize bidi_it->string.s and
16300 bidi_it->string.schars.
16301 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16302 NULL (avoids a crash in bidi_paragraph_init).
16303 Initialize itb.string.lstring.
16304 (init_iterator): Call bidi_init_it only of a valid
16305 buffer position was specified. Initialize paragraph_embedding to
16307 (reseat_to_string): Initialize the bidi iterator.
16308 (display_string): If we need to ignore text properties of
16309 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16310 original value of -1 will not work with bidi.)
16311 (compute_display_string_pos): First arg is now struct
16312 `text_pos *'; all callers changed. Support display properties on
16314 (compute_display_string_end): Support display properties on Lisp
16316 (init_iterator, reseat_1, reseat_to_string): Initialize the
16317 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16318 when iterating on a string not from display properties).
16319 (compute_display_string_pos, compute_display_string_end):
16320 Fix calculation of the object to scan. Fixes an error when using
16322 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16323 base_level_stop; instead, set base_level_stop to BEGV.
16324 Fixes crashes in vertical-motion.
16325 (next_element_from_buffer): Improve commentary for when
16326 the iterator is before prev_stop.
16327 (init_iterator): Initialize bidi_p from the default value of
16328 bidi-display-reordering, not from buffer-local value. Use the
16329 buffer-local value only if initializing for buffer iteration.
16330 (handle_invisible_prop): Support invisible properties on strings
16331 that are being bidi-reordered.
16332 (set_iterator_to_next): Support bidi reordering of C strings and
16334 (next_element_from_string): Support bidi reordering of Lisp
16336 (handle_stop_backwards): Support Lisp strings as well.
16337 (display_string): Support display of R2L glyph rows.
16338 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16339 (init_iterator): Don't initialize it->bidi_p for strings
16341 (reseat_to_string): Initialize it->bidi_p for strings here.
16342 (next_element_from_string, next_element_from_c_string)
16343 (next_element_from_buffer): Add xassert's for correspondence
16344 between IT's object being iterated and it->bidi_it.string

16347 (next_element_from_c_string): Handle the case of the first string
16348 character that is not the first one in the visual order.
16349 (get_visually_first_element): New function, refactored from common
16350 parts of next_element_from_buffer, next_element_from_string, and
16351 next_element_from_c_string.
16352 (tool_bar_lines_needed, redisplay_tool_bar)
16353 (display_menu_bar): Force left-to-right direction. Add a FIXME
16354 comment for making that be controlled by a user option.
16355 (push_it, pop_it): Save and restore the state of the
16356 bidi iterator. Save and restore the bidi_p flag.
16357 (pop_it): Iterate out of display property for string iteration as
16359 (iterate_out_of_display_property): Support iteration over strings.
16360 (handle_single_display_spec): Set up it->bidi_it for iteration
16361 over a display string, and call bidi_init_it.
16362 (handle_single_display_spec, next_overlay_string)
16363 (get_overlay_strings_1, push_display_prop): Set up the bidi
16364 iterator for displaying display or overlay strings.
16365 (forward_to_next_line_start): Don't use the shortcut if
16367 (back_to_previous_visible_line_start): If handle_display_prop
16368 pushed the iterator stack, restore the internal state of the bidi
16369 iterator by calling bidi_pop_it same number of times.
16370 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16371 and we are bidi-iterating, don't decrement the iterator position;
16372 instead, set the first_elt flag in the bidi iterator, to produce
16374 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16375 (push_display_prop): xassert that we are iterating a buffer.
16376 (push_it, pop_it): Save and restore paragraph_embedding member.
16377 (handle_single_display_spec, next_overlay_string)
16378 (get_overlay_strings_1, reseat_1, reseat_to_string)
16379 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16380 correctly. Don't assume unibyte strings are not bidi-reordered.
16381 (compute_display_string_pos)
16382 (compute_display_string_end): Fix handling the case of C string.
16383 (push_it, pop_it): Save and restore from_disp_prop_p.

16388 popping after iteration over a string that came from a display
16389 property. Fix a typo in popping stretch info. Add an assertion
16390 for verifying that the iterator position is in sync with the bidi
16392 (handle_single_display_spec, get_overlay_strings_1)
16393 (push_display_prop): Fix initialization of paragraph direction for
16394 string when that of the parent object is not yet determined.
16395 (reseat_1): Call bidi_init_it to resync the bidi
16396 iterator with IT's position. (Bug#7616)
16397 (find_row_edges): If ROW->start.pos gives position
16398 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
16399 (handle_stop, back_to_previous_visible_line_start, reseat_1):
16400 Reset the from_disp_prop_p flag.
16401 (SAVE_IT, RESTORE_IT): New macros.

16406 (try_scrolling, redisplay_window, display_line): Use them when
16407 saving a temporary copy of the iterator and restoring it back.
16408 (back_to_previous_visible_line_start, reseat_1)
16409 (init_iterator): Empty the bidi cache "stack".
16410 (move_it_in_display_line_to): If iterator ended up at
16411 EOL, but we never saw any buffer positions smaller than
16412 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16413 motion in bidi-reordered lines.
16414 (move_it_in_display_line_to): Record prev_method and prev_pos
16415 immediately before the call to set_iterator_to_next. Fixes cursor
16416 motion in bidi-reordered lines with stretch glyphs and strings
16417 displayed in margins. (Bug#8133) (Bug#8867)
16418 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16420 (pos_visible_p): Support positions in bidi-reordered lines.
16421 Save and restore bidi cache.
16423 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16424 (bidi_paragraph_info): Delete unused struct.
16425 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
16426 (bidi_cache_start): New variable.
16427 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

16435 (bidi_fetch_char): Accept new argument STRING; all callers
16436 changed. Support iteration over a string. Support strings with
16437 display properties. Support unibyte strings. Fix the type of
16438 `len' according to what STRING_CHAR_AND_LENGTH expects.
16439 (bidi_paragraph_init, bidi_resolve_explicit_1)
16440 (bidi_resolve_explicit, bidi_resolve_weak)
16441 (bidi_level_of_next_char, bidi_move_to_visually_next):
16442 Support iteration over a string.
16443 (bidi_set_sor_type, bidi_resolve_explicit_1)
16444 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16445 can now be zero (for strings); special values 0 and -1 were
16446 changed to -1 and -2, respectively.
16447 (bidi_char_at_pos): New function.
16448 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
16449 Call it instead of FETCH_MULTIBYTE_CHAR.

16459 (bidi_initialize): Initialize the bidi cache start stack pointer.
16460 (bidi_cache_ensure_space): New function, refactored from part of

16464 (bidi_count_bytes, bidi_char_at_pos): New functions.
16465 (bidi_cache_search): Don't assume bidi_cache_last_idx is

16534 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16536 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16537 The old code sometimes used this field without initializing it.
16539 * alloc.c (gc_sweep): Don't read past end of array.
16540 In theory, the old code could also have corrupted Emacs internals,
16541 though it'd be very unlikely.

16545 * character.c (Fcharacterp): Don't advertise optional ignored

16644 Use pthread_sigmask, not sigprocmask (Bug#9010).
16645 sigprocmask is portable only for single-threaded applications, and
16646 Emacs can be multi-threaded when it uses GTK.

16804 (clone_per_buffer_values): Don't assume that

16806 This isn't true in general, and it's particularly not true
16807 if Emacs is configured with --with-wide-int.
16808 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16809 New macros, used in the buffer.c change.

16845 Random fixes. E.g., (random) never returned negative values.
16846 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16847 subseconds part to the entropy, as that's a bit more random.
16848 Prefer signed to unsigned, since the signedness doesn't matter and
16849 in general we prefer signed. When given a limit, use a
16850 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16851 latter isn't right if USE_2_TAGS_FOR_INTS.
16852 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16853 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16863 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
16865 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16866 This is more efficient than Ffile_directory_p and avoids a minor race.
16868 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16870 * buffer.c (Foverlay_put): Say what the return value is
16873 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16874 is a directory before asking whether to use the file name
16876 (barf_or_query_if_file_exists): Make the "File is a directory"
16877 error be more correct.
16879 * fns.c (Frequire): Remove the mention of the .gz files, since
16880 that's installation-specific, but keep the mention of
16881 `get-load-suffixes'.
16883 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
16885 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16893 Qgnutls_bootprop_verify_error (which is no longer used).
16895 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16896 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16897 Also (re)move comments that are misplaced or no longer relevant.
16899 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16901 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16998 * eval.c (struct backtrace): Simplify and port the data structure.
16999 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17000 signed bit field, as this assumption is not portable and it makes
17001 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17002 "char debug_on_exit : 1" as this is not portable either; instead,
17003 use the portable "unsigned int debug_on_exit : 1". Remove unused
17004 member evalargs. Remove obsolete comments about cc bombing out.

17194 (read1): Check for integer overflow in radices, and in
17195 read-circle numbers.

17240 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17241 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17242 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17243 since we're not interested in debugging glyphs with old libraries.
17244 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17245 GCC 4.6.0's static checking.

17287 (x_session_initialize): Do not assume string length fits in int.
17289 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

17338 Use memcpy, not strncpy, where memcpy is what is really wanted.
17339 Don't assume (via atoi) that time_t and pid_t fit in int.
17340 Check for time_t and/or pid_t out of range, e.g., via a network share.
17341 Don't alloca where an auto var works fine.

17357 We prefer signed integers, even for size calculations.
17359 * emacs.c: Don't assume string length fits in 'int'.
17360 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17361 (main): Don't invoke strlen when not needed.
17363 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17364 (XD_DEBUG_MESSAGE): Don't waste a byte.
17366 * callproc.c (getenv_internal_1, getenv_internal)
17367 (Fgetenv_internal):
17368 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17370 * lread.c (invalid_syntax): Omit length argument.
17371 All uses changed. This doesn't fix a bug, but it simplifies the
17372 code away from its former Hollerith-constant appearance, and it's
17373 one less 'int' to worry about when looking at integer-overflow issues.
17374 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17376 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17377 This didn't break anything, but it didn't help either.
17378 It's confusing to put a bogus integer in a place where the actual
17379 value does not matter.
17380 (LIST_END_P): Remove unused macro and its bogus comment.
17381 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17383 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17384 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17386 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17387 We prefer signed types, and the value cannot exceed the EMACS_INT
17388 range anyway (because otherwise the length would not be representable).
17389 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17390 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17391 This avoids a GCC warning when WIDE_EMACS_INT.
17393 * indent.c (sane_tab_width): New function.
17394 (current_column, scan_for_column, Findent_to, position_indentation)
17395 (compute_motion): Use it. This is just for clarity.
17396 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17398 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17400 * lisp.h (lint_assume): New macro.
17401 * composite.c (composition_gstring_put_cache):
17402 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17404 * editfns.c, insdel.c:
17405 Omit unnecessary forward decls, to simplify future changes.
17407 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17409 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17411 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17412 Use much-faster test for byte-length change.
17413 Don't assume string byte-length fits in 'int'.
17414 Check that character arg fits in 'int'.
17415 (mapcar1): Declare byte as byte, for clarity.
17417 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17419 * fns.c (concat): Catch string overflow earlier.
17420 Do not rely on integer wraparound.
17422 * dispextern.h (struct it.overlay_strings_charpos)
17423 (struct it.selective): Now EMACS_INT, not int.
17424 * xdisp.c (forward_to_next_line_start)
17425 (back_to_previous_visible_line_start)
17426 (reseat_at_next_visible_line_start, next_element_from_buffer):
17427 Don't arbitrarily truncate the value of 'selective' to int.
17429 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17431 * composite.c: Don't truncate sizes to 'int'.
17432 (composition_gstring_p, composition_reseat_it)
17433 (composition_adjust_point): Use EMACS_INT, not int.
17434 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17435 not EMACS_UINT, for indexes.
17437 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17439 * buffer.c: Include <verify.h>.
17440 (struct sortvec.priority, struct sortstr.priority):
17441 Now EMACS_INT, not int.
17442 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17443 (struct sortstr.size, record_overlay_string)
17444 (struct sortstrlist.size, struct sortlist.used):
17445 Don't truncate size to int.
17446 (record_overlay_string): Check for size-calculation overflow.
17447 (init_buffer_once): Check at compile-time, not run-time.
17449 2011-06-22 Jim Meyering <meyering@redhat.com>
17451 Don't leak an XBM-image-sized buffer
17452 * image.c (xbm_load): Free the image buffer after using it.
17454 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17457 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17458 that Sun C diagnosed.
17459 * fns.c (secure_hash): Fix pointer signedness issue.
17460 * intervals.c (static_offset_intervals): New function.
17461 (offset_intervals): Use it.
17463 2011-06-21 Leo Liu <sdl.web@gmail.com>
17466 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17469 * fns.c (secure_hash): Rename from crypto_hash_function and change
17470 the first arg to accept symbols.
17471 (Fsecure_hash): New primitive.
17472 (syms_of_fns): New symbols.
17474 2011-06-20 Deniz Dogan <deniz@dogan.se>
17476 * process.c (Fset_process_buffer): Clarify return value in
17479 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17481 * dispnew.c (add_window_display_history): Use BVAR.
17483 * xdisp.c (debug_method_add): Use BVAR.
17484 (check_window_end, dump_glyph_matrix, dump_glyph)
17485 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17487 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17490 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17491 check till after the cache is created in init_frame_faces.
17493 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17495 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17497 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17499 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17500 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17501 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17503 Improve buffer-overflow checking (Bug#8873).
17504 * fileio.c (Finsert_file_contents):
17505 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17506 Remove the old (too-loose) buffer overflow checks.
17507 They weren't needed, since make_gap checks for buffer overflow.
17508 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17509 The old code merely checked for Emacs fixnum overflow, and relied
17510 on undefined (wraparound) behavior. The new code avoids undefined
17511 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17513 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17514 Tune. Don't use wider integers than needed. Don't use alloca.
17515 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17517 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17519 * insdel.c, lisp.h (buffer_overflow): New function.
17520 (insert_from_buffer_1, replace_range, replace_range_2):
17521 * insdel.c (make_gap_larger):
17522 * editfns.c (Finsert_char):
17523 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17525 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17527 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17529 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17531 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17532 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17534 * fileio.c: Don't assume EMACS_INT fits in off_t.
17535 (emacs_lseek): New static function.
17536 (Finsert_file_contents, Fwrite_region): Use it.
17537 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17539 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17541 * fns.c: Don't overflow int when computing a list length.
17542 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17543 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17544 truncation on 64-bit hosts. Check for QUIT every
17545 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17546 faster and is responsive enough.
17547 (Flength): Report an error instead of overflowing an integer.
17548 (Fsafe_length): Return a float if the value is not representable
17549 as a fixnum. This shouldn't happen except in contrived situations.
17550 (Fnthcdr, Fsort): Don't assume list length fits in int.
17551 (Fcopy_sequence): Don't assume vector length fits in int.
17553 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17554 (header_size, word_size): New constants.
17555 (allocate_vectorlike): Don't check size overflow here.
17556 (allocate_vector): Check it here instead, since this is the only
17557 caller of allocate_vectorlike that could cause overflow.
17558 Check that the new vector's length is representable as a fixnum.
17560 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17561 The previous code was bogus. For example, next_almost_prime (32)
17562 returned 39, which is undesirable as it is a multiple of 3; and
17563 next_almost_prime (24) returned 25, which is a multiple of 5 so
17564 why was the code bothering to check for multiples of 7?
17566 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17568 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17570 Variadic C functions now count arguments with ptrdiff_t.
17571 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17572 Back then I didn't know that the Emacs coding style prefers signed int.
17573 Also, in the meantime I found a few more instances where arguments
17574 were being counted with int, which may truncate counts on 64-bit
17575 machines, or EMACS_INT, which may be unnecessarily wide.
17576 * lisp.h (struct Lisp_Subr.function.aMANY)
17577 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17578 Arg counts are now ptrdiff_t, not size_t.
17579 All variadic functions and their callers changed accordingly.
17580 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17581 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17582 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17583 * callint.c (Fcall_interactively): Check arg count for overflow,
17584 to avoid potential buffer overrun. Use signed char, not 'int',
17585 for 'varies' array, so that we needn't bother to check its size
17586 calculation for overflow.
17587 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17588 * eval.c (apply_lambda):
17589 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17590 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17591 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17593 * callint.c (Fcall_interactively): Don't use index var as event count.
17595 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17596 * mem-limits.h (SIZE): Remove; no longer used.
17598 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17600 Remove unnecessary casts.
17601 * xterm.c (x_term_init):
17602 * xfns.c (x_set_border_pixel):
17603 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17604 These aren't needed now that we assume ANSI C.
17606 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17607 It's more likely to cause problems (due to unsigned overflow)
17610 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17612 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17614 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17616 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17618 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17620 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17622 GLYPH_CODE_FACE returns EMACS_INT, not int.
17623 * dispextern.h (merge_faces):
17624 * xfaces.c (merge_faces):
17625 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17626 Don't assume EMACS_INT fits in int.
17628 * character.h (CHAR_VALID_P): Remove unused parameter.
17629 * fontset.c, lisp.h, xdisp.c: All uses changed.
17631 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17633 * fns.c (concat): Minor tuning based on overflow analysis.
17634 This doesn't fix any bugs. Use int to hold character, instead
17635 of constantly refetching from Emacs object. Use XFASTINT, not
17636 XINT, for value known to be a character. Don't bother comparing
17637 a single byte to 0400, as it's always less.
17639 * floatfns.c (Fexpt):
17640 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17642 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17645 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17647 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17648 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17649 incorrectly succeed when S was a string, because 4294967386 was
17650 truncated before it was used.
17652 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17653 Otherwise, an out-of-range integer could cause undefined behavior
17656 * composite.c: Use int, not EMACS_INT, for characters.
17657 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17658 EMACS_INT, for values that are known to be in character range.
17659 This doesn't fix any bugs but is the usual style inside Emacs and
17660 may generate better code on 32-bit machines.
17662 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17663 This is for reasons similar to the recent CHAR_STRING fix.
17664 * charset.c (Fencode_char): Check that character arg is actually
17665 a character. Pass an int to ENCODE_CHAR.
17666 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17667 wider than 'int', as a compile-time check to prevent future regressions
17670 * character.c (char_string): Remove unnecessary casts.
17672 Make sure a 64-bit char is never passed to CHAR_STRING.
17673 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17674 by silently ignoring the top 32 bits, allowing some values
17675 that were far too large to be valid characters.
17676 * character.h: Include <verify.h>.
17677 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17678 arguments are no wider than unsigned, as a compile-time check
17679 to prevent future regressions in this area.
17681 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17682 (Fsubst_char_in_region):
17684 * xdisp.c (decode_mode_spec_coding):
17685 Adjust to CHAR_STRING's new requirement.
17686 * editfns.c (Finsert_char, Fsubst_char_in_region):
17687 * fns.c (concat): Check that character args are actually
17688 characters. Without this test, these functions did the wrong
17689 thing with wildly out-of-range values on 64-bit hosts.
17691 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17692 These casts should not be needed on 32-bit hosts, either.
17693 * keyboard.c (read_char):
17694 * lread.c (Fload): Remove casts to unsigned.
17696 * lisp.h (UNSIGNED_CMP): New macro.
17697 This fixes comparison bugs on 64-bit hosts.
17698 (ASCII_CHAR_P): Use it.
17699 * casefiddle.c (casify_object):
17700 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17701 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17702 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17703 * dispextern.h (FACE_FROM_ID):
17704 * keyboard.c (read_char): Use UNSIGNED_CMP.
17706 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17707 not to EMACS_INT, to avoid GCC warning.
17709 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17711 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17712 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17713 isn't needed on 32-bit machines.
17715 * buffer.c (Fgenerate_new_buffer_name):
17716 Use EMACS_INT for count, not int.
17717 (advance_to_char_boundary): Return EMACS_INT, not int.
17719 * data.c (Qcompiled_function): Now static.
17721 * window.c (window_body_lines): Now static.
17723 * image.c (gif_load): Rename local to avoid shadowing.
17725 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17726 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17727 * alloc.c (make_save_value): Integer argument is now of type
17728 ptrdiff_t, not int.
17729 (mark_object): Use ptrdiff_t, not int.
17730 * lisp.h (pD): New macro.
17731 * print.c (print_object): Use it.
17733 * alloc.c: Use EMACS_INT, not int, to count objects.
17734 (total_conses, total_markers, total_symbols, total_vector_size)
17735 (total_free_conses, total_free_markers, total_free_symbols)
17736 (total_free_floats, total_floats, total_free_intervals)
17737 (total_intervals, total_strings, total_free_strings):
17738 Now EMACS_INT, not int. All uses changed.
17739 (Fgarbage_collect): Compute overall total using a double, so that
17740 integer overflow is less likely to be a problem. Check for overflow
17741 when converting back to an integer.
17742 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17743 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17744 These were 'int' variables that could overflow on 64-bit hosts;
17745 they were never used, so remove them instead of repairing them.
17746 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17747 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17748 Previously, this ceilinged at INT_MAX, but that doesn't work on
17750 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17752 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17753 (allocate_vectorlike): Check for ptrdiff_t overflow.
17754 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17755 when a (possibly-narrower) signed value would do just as well.
17756 We prefer using signed arithmetic, to avoid comparison confusion.
17758 * alloc.c: Catch some string size overflows that we were missing.
17759 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17760 for convenience in STRING_BYTES_MAX.
17761 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17762 The definition here is exact; the one in lisp.h was approximate.
17763 (allocate_string_data): Check for string overflow. This catches
17764 some instances we weren't catching before. Also, it catches
17765 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17766 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17767 and ptrdiff_t and EMACS_INT are both 64 bits.
17769 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17770 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17771 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17773 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17775 * alloc.c (Fmake_string): Check for out-of-range init.
17777 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17779 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17781 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17783 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17784 xg_get_default_scrollbar_width.
17786 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17787 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17788 (style_changed_cb): Call update_theme_scrollbar_width and call
17789 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17790 all frames (Bug#8505).
17791 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17792 Call gtk_window_set_resizable if HAVE_GTK3.
17793 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17794 and height if HAVE_GTK3 (Bug#8505).

18241 Fframe_first_window and Fset_frame_selected_window to window.h.
18243 * window.h: Move EXFUNS for Fframe_root_window,

18248 (Fframe_root_window, Fframe_selected_window)
18249 (Fset_frame_selected_window): Move to window.c.
18250 (Factive_minibuffer_window): Move to minibuf.c.
18251 (Fother_visible_frames_p): New function.

18267 (Fwindow_minibuffer_p): Move up in code and simplify.
18268 (Fset_frame_selected_window): Move here from frame.c.
18270 (Fselected_window, select_window, Fselect_window): Move up in
18271 code. Minor doc-string fixes.
18273 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18275 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18276 Do not assume that spare memory exists; that assumption is valid
18277 only if SYSTEM_MALLOC.
18278 (LARGE_REQUEST): New macro, so that the issue of large requests
18279 is separated from the issue of spare memory.
18281 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
18283 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

18309 New error handlers.
18310 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18311 Obey Vx_select_enable_clipboard_manager. Catch errors in
18312 x_clipboard_manager_save (Bug#8779).
18313 (Vx_select_enable_clipboard_manager): New variable.
18314 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18316 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18318 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18320 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18322 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap

18329 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18331 Support bidi reordering of text covered by display properties.
18333 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18334 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18335 (bidi_cache_search, bidi_cache_iterator_state)
18336 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18337 (bidi_level_of_next_char, bidi_move_to_visually_next):
18338 Support character positions inside a run of characters covered by a
18340 (bidi_paragraph_init, bidi_resolve_explicit_1)
18341 (bidi_level_of_next_char): Call bidi_fetch_char and
18342 bidi_fetch_char_advance instead of FETCH_CHAR and
18343 FETCH_CHAR_ADVANCE.
18344 (bidi_init_it): Initialize new members.
18345 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18347 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18348 instead of using explicit *_CHAR codes.
18349 (bidi_resolve_explicit, bidi_resolve_weak):
18350 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18351 bidirectional text is supported only in multibyte buffers.
18352 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18353 it to initialize the frame_window_p member of struct bidi_it.
18354 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18355 (bidi_resolve_explicit, bidi_resolve_weak)

18357 bidi_it->nchars is non-positive.
18358 (bidi_level_of_next_char): Don't try to lookup the cache for the
18359 next/previous character if nothing is cached there yet, or if we
18360 were just reseat()'ed to a new position.
18362 * xdisp.c (set_cursor_from_row): Set start and stop points
18363 according to the row's direction when priming the loop that looks
18364 for the glyph on which to display cursor.
18365 (single_display_spec_intangible_p): Function deleted.
18366 (display_prop_intangible_p): Reimplement to call
18367 handle_display_spec instead of single_display_spec_intangible_p.
18368 Accept 3 additional arguments needed by handle_display_spec.
18369 This fixes incorrect cursor motion across display property with complex
18370 values: lists, `(when COND...)' forms, etc.
18371 (single_display_spec_string_p): Support property values that are
18372 lists with the argument STRING its top-level element.
18373 (display_prop_string_p): Fix the condition for processing a
18374 property that is a list to be consistent with handle_display_spec.
18375 (handle_display_spec): New function, refactored from the
18376 last portion of handle_display_prop.
18377 (compute_display_string_pos): Accept additional argument
18378 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18379 value of a `display' property is a "replacing spec".
18380 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18381 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18382 the display property, but just return a value indicating whether
18383 the display property will replace the characters it covers.
18384 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18385 frame_window_p members of struct bidi_it.
18386 (compute_display_string_pos, compute_display_string_end):
18388 (push_it): Accept second argument POSITION, where pop_it should
18389 jump to continue iteration.
18390 (reseat_1): Initialize bidi_it.disp_pos.
18392 * keyboard.c (adjust_point_for_property): Adjust the call to
18393 display_prop_intangible_p to its new signature.
18395 * dispextern.h (struct bidi_it): New member frame_window_p.
18396 (bidi_init_it): Update prototypes.
18397 (display_prop_intangible_p): Update prototype.
18398 (compute_display_string_pos, compute_display_string_end):
18399 Declare prototypes.
18400 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18403 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18405 Malloc failure behavior now depends on size of allocation.
18406 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18407 * lisp.h: Change signatures accordingly.
18408 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18409 All callers changed. (Bug#8762)
18411 * gnutls.c: Use Emacs's memory allocators.
18412 Without this change, the gnutls library would invoke malloc etc.
18413 directly, which causes problems on non-SYNC_INPUT hosts, and which
18414 runs afoul of improving memory_full behavior. (Bug#8761)
18415 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18416 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18417 xfree instead of the default malloc, realloc, free.
18418 (Fgnutls_boot): No need to check for memory allocation failure,
18419 since xmalloc does that for us.
18421 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18422 * category.c (hash_get_category_set):
18423 * ccl.c (ccl_driver):
18424 * charset.c (Fdefine_charset_internal):
18425 * charset.h (struct charset.hash_index):
18426 * composite.c (get_composition_id, gstring_lookup_cache)
18427 (composition_gstring_put_cache):
18428 * composite.h (struct composition.hash_index):
18429 * dispextern.h (struct image.hash):

18431 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
18432 (hashfn_equal, hashfn_user_defined, make_hash_table)

18434 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18435 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18436 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18437 * image.c (make_image, search_image_cache, lookup_image)
18438 (xpm_put_color_table_h):
18439 * lisp.h (struct Lisp_Hash_Table):
18440 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18441 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18442 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18443 * alloc.c (allocate_vectorlike):
18444 Check for overflow in vector size calculations.
18445 * ccl.c (ccl_driver):
18446 Check for overflow when converting EMACS_INT to int.
18447 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18448 need to be updated by these changes.
18449 * fns.c (make_hash_table, maybe_resize_hash_table):
18450 Check for integer overflow with large hash tables.
18451 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18452 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18453 (SXHASH_REDUCE): New macro.
18454 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18455 Use it instead of discarding useful hash info with large hash values.
18456 (sxhash_float): New function.
18457 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18458 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18459 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18460 Rewrite to use FIXNUM_BITS, as this simplifies things.
18461 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18462 Adjust signatures to match updated version of code.
18463 (consing_since_gc): Now EMACS_INT, since a single hash table can
18464 use more than INT_MAX bytes.
18466 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18468 Make it possible to build with GCC-4.6+ -O2 -flto.
18470 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18472 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18474 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18475 Call minibuffer-inactive-mode.
18477 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18479 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18480 Update dependencies.
18482 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18484 * data.c (init_data): Remove code for UTS, this system is not
18487 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18489 Don't force ./temacs to start in terminal mode.
18491 * frame.c (make_initial_frame): Initialize faces in all cases, not
18492 only when CANNOT_DUMP is defined.
18493 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18495 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18497 * dispnew.c (add_window_display_history): Use const for the string
18498 pointer. Remove declaration, not needed.
18500 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18502 Use 'inline', not 'INLINE'.
18503 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18504 * alloc.c, fontset.c (INLINE): Remove.
18505 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18506 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18507 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18508 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18509 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18511 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18513 Make it possible to run ./temacs.
18515 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18516 syms_of_callproc does the same thing. Remove test for
18517 "initialized", do it in the caller.
18518 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18520 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18522 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18523 (read_minibuf): Use get_minibuffer.
18524 (syms_of_minibuf): Use DEFSYM.
18525 (Qmetadata): New var.
18526 * data.c (Qbuffer): Don't make it static.
18527 (syms_of_data): Use DEFSYM.
18529 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18531 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18532 (CCL_CODE_MIN): New macro.
18534 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18536 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18538 * eval.c (Qdebug): Now static.
18539 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18540 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18541 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18543 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18545 * image.c: Various fixes to ImageMagick code comments.
18546 (Fimagemagick_types): Doc fix.
18548 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18550 Minor fixes prompted by GCC 4.6.0 warnings.
18552 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18554 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18555 (x_clipboard_manager_save_all): Move extern decl to ...
18556 * xterm.h: ... here, so that it can be checked for consistency.
18558 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18560 * xselect.c (x_clipboard_manager_save_frame)
18561 (x_clipboard_manager_save_all): New functions.
18562 (Fx_clipboard_manager_save): Lisp function deleted.
18564 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18565 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18567 * xterm.h: Update prototype.
18569 2011-05-28 William Xu <william.xwl@gmail.com>
18571 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18572 exiting (Bug#8239).
18574 2011-05-28 Jim Meyering <meyering@redhat.com>
18576 Avoid a sign-extension bug in crypto_hash_function.
18577 * fns.c (to_uchar): Define.
18578 (crypto_hash_function): Use it to convert some newly-signed
18579 variables to unsigned, to avoid sign-extension bugs. For example,
18580 without this change, (md5 "truc") would evaluate to
18581 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18582 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18583 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18585 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18587 Integer overflow fixes.
18589 * dbusbind.c: Serial number integer overflow fixes.
18590 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18591 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18592 to hold a serial number that is too large for a fixnum.
18593 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18594 Check for serial numbers out of range. Decode any serial number
18595 that was so large that it became a float. (Bug#8722)
18597 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18598 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18599 Use XFASTINT rather than XUINT when numbers are nonnegative.
18600 (xd_append_arg, Fdbus_method_return_internal):
18601 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18602 arguments, check that Lisp number is nonnegative, rather than
18603 silently wrapping negative numbers around. (Bug#8722)
18604 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18607 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18609 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18611 ccl: Add integer overflow checks.
18612 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18613 (IN_INT_RANGE): New macros.
18614 (ccl_driver): Use them to check for integer overflow when
18615 decoding a CCL program. Many of the new checks are whether XINT (x)
18616 fits in int; it doesn't always, on 64-bit hosts. The new version
18617 doesn't catch all possible integer overflows, but it's an
18618 improvement. (Bug#8719)
18620 * alloc.c (make_event_array): Use XINT, not XUINT.
18621 There's no need for unsigned here.
18623 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18624 This follows up to the 2011-05-06 change that substituted uintptr_t
18625 for EMACS_INT. This case wasn't caught back then.
18627 Rework Fformat to avoid integer overflow issues.
18628 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18629 now (part of C89). Include <verify.h>.
18630 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18631 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18632 (Fformat): Avoid the prepass trying to compute sizes; it was only
18633 approximate and thus did not catch overflow reliably. Instead, walk
18634 through the format just once, formatting and computing sizes as we go,
18635 checking for integer overflow at every step, and allocating a larger
18636 buffer as needed. Keep track separately whether the format is
18637 multibyte. Keep only the most-recently calculated precision, rather
18638 than them all. Record whether each argument has been converted to
18639 string. Use EMACS_INT, not int, for byte and char and arg counts.
18640 Support field widths and precisions larger than INT_MAX. Avoid
18641 sprintf's undefined behavior with conversion specifications such as %#d
18642 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18643 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18644 formatting out-of-range floating point numbers with int
18645 formats. (Bug#8668)
18647 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18649 * data.c: Avoid integer truncation in expressions involving floats.
18650 * data.c: Include <intprops.h>.
18651 (arith_driver): When there's an integer overflow in an expression
18652 involving floating point, convert the integers to floating point
18653 so that the resulting value does not suffer from catastrophic
18654 integer truncation. For example, on a 64-bit host (* 4
18655 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18656 Do not rely on undefined behavior after integer overflow.
18658 merge count_size_as_multibyte, parse_str_to_multibyte
18659 * character.c, character.h (count_size_as_multibyte):
18660 Rename from parse_str_to_multibyte; all uses changed.
18661 Check for integer overflow.
18662 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18663 since it's now a duplicate of the other. This is more of
18664 a character than a buffer op, so better that it's in character.c.
18665 * fns.c, print.c: Adjust to above changes.
18667 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18669 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18671 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18673 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18674 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18675 (x_clipboard_manager_save): Now static.
18676 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18678 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18679 (crypto_hash_function): Now static.
18680 Fix pointer signedness problems. Avoid unnecessary initializations.
18682 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18684 * termhooks.h (Vselection_alist): Make it terminal-local.
18686 * terminal.c (create_terminal): Initialize it.
18688 * xselect.c: Support for clipboard managers.
18689 (Vselection_alist): Move to termhooks.h as terminal-local var.
18690 (LOCAL_SELECTION): New macro.
18691 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18692 (symbol_to_x_atom): Remove gratuitous arg.
18693 (x_handle_selection_request, lisp_data_to_selection_data)
18694 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18695 (x_own_selection, x_get_local_selection, x_convert_selection):
18696 New arg, specifying work frame. Use terminal-local Vselection_alist.
18697 (some_frame_on_display): Delete unused function.
18698 (Fx_own_selection_internal, Fx_get_selection_internal)
18699 (Fx_disown_selection_internal, Fx_selection_owner_p)
18700 (Fx_selection_exists_p): New optional frame arg.
18701 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18702 (x_handle_selection_clear): Don't treat other terminals with the
18703 same keyboard specially. Use the terminal-local Vselection_alist.
18704 (x_clear_frame_selections): Use Frun_hook_with_args.
18706 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18708 * xterm.h: Add support for those atoms.
18710 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18712 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18713 (converted_selections, conversion_fail_tag): New global variables.
18714 (x_selection_request_lisp_error): Free the above.
18715 (x_get_local_selection): Remove unnecessary code.
18716 (x_reply_selection_request): Args changed; handle arbitrary array
18717 of converted selections stored in converted_selections.
18718 Separate the XChangeProperty and SelectionNotify steps.
18719 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18720 (x_convert_selection): New function.
18721 (x_handle_selection_event): Simplify.
18722 (x_get_foreign_selection): Don't ignore incoming requests while
18723 waiting for an answer; this will fail when we implement
18724 SAVE_TARGETS, and seems unnecessary anyway.
18725 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18726 (Vx_sent_selection_functions): Doc fix.
18728 2011-05-26 Leo Liu <sdl.web@gmail.com>
18730 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18732 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18734 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18736 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18737 for fringe update if it has periodic bitmap.
18738 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18739 and fringe_bitmap_periodic_p.
18741 * fringe.c (get_fringe_bitmap_data): New function.
18742 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18743 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18744 row. Mark glyph row for fringe update if periodicity changed.
18746 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18747 for fringe update unless it has periodic bitmap.
18749 2011-05-25 Kenichi Handa <handa@m17n.org>
18751 * xdisp.c (get_next_display_element): Set correct it->face_id for
18752 a static composition.
18754 2011-05-24 Leo Liu <sdl.web@gmail.com>
18757 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18759 * fns.c (crypto_hash_function, Fsha1): New function.
18760 (Fmd5): Use crypto_hash_function.
18761 (syms_of_fns): Add Ssha1.
18763 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18765 * gnutls.c: Remove unused macros.
18766 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18767 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18768 Remove macros that are defined and never used.
18769 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18771 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18773 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18774 (Fx_get_selection_internal): Minor cleanup.
18775 (Fx_own_selection_internal): Rename arguments for consistency with
18778 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18780 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18782 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18784 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18786 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18788 * dispnew.c (scrolling_window): Don't exclude the case that the
18789 last enabled row in the desired matrix touches the bottom boundary.
18791 2011-05-21 Glenn Morris <rgm@gnu.org>
18793 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18794 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18795 and add some more files.
18797 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18799 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18800 report_file_error introduced by the change from 2011-05-07.
18802 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18804 * systime.h (Time): Define only if emacs is defined.
18805 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18806 where the include path doesn't have X11/X.h by default. See
18807 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18809 2011-05-20 Kenichi Handa <handa@m17n.org>
18811 * composite.c (find_automatic_composition): Fix previous change.
18813 2011-05-20 Glenn Morris <rgm@gnu.org>
18815 * lisp.mk: New file, split from Makefile.in.
18816 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18817 (shortlisp): Remove.
18818 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18820 2011-05-19 Glenn Morris <rgm@gnu.org>
18822 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18823 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18824 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18825 (lisp): Set the order to that of loadup.el.
18826 (shortlisp): Make it a copy of $lisp.
18827 (SOME_MACHINE_LISP): Remove.
18828 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18829 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18831 2011-05-18 Kenichi Handa <handa@m17n.org>
18833 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18834 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18835 (find_automatic_composition): Mostly rewrite for efficiency.
18837 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18839 * makefile.w32-in: Update dependencies.
18841 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18843 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18844 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18846 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18848 Fix some integer overflow issues, such as string length overflow.
18850 * insdel.c (count_size_as_multibyte): Check for string overflow.
18852 * character.c (lisp_string_width): Check for string overflow.
18853 Use EMACS_INT, not int, for string indexes and lengths; in
18854 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18855 the resulting string length overflows an EMACS_INT; instead,
18856 report a string overflow if no precision given. When checking for
18857 precision exhaustion, use a check that cannot possibly have
18858 integer overflow. (Bug#8675)
18859 * character.h (lisp_string_width): Adjust to new signature.
18861 * alloc.c (string_overflow): New function.
18862 (Fmake_string): Use it. This doesn't change behavior, but saves
18863 a few bytes and will simplify future changes.
18864 * character.c (string_escape_byte8): Likewise.
18865 * lisp.h (string_overflow): New decl.
18867 Fixups, following up to the user-interface timestamp change.
18868 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18869 for UI timestamps, instead of unsigned long.
18870 * msdos.c (mouse_get_pos): Likewise.
18871 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18872 * w32gui.h (Time): Define by including "systime.h" rather than by
18873 declaring it ourselves. (Bug#8664)
18875 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18876 * image.c (clear_image_cache): Likewise.
18878 * term.c (term_mouse_position): Don't assume time_t wraparound.
18880 Be more systematic about user-interface timestamps.
18881 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18882 and sometimes 'EMACS_UINT', to represent these timestamps.
18883 This change causes it to use 'Time' uniformly, as that's what X uses.
18884 This makes the code easier to follow, and makes it easier to catch
18885 integer overflow bugs such as Bug#8664.
18886 * frame.c (Fmouse_position, Fmouse_pixel_position):
18887 Use Time, not unsigned long, for user-interface timestamps.
18888 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18889 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18890 * keyboard.h (last_event_timestamp): Likewise.
18891 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18892 * menu.h (xmenu_show): Likewise.
18893 * term.c (term_mouse_position): Likewise.
18894 * termhooks.h (struct input_event.timestamp): Likewise.
18895 (struct terminal.mouse_position_hook): Likewise.
18896 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18897 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18898 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18899 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18900 what it was before.
18901 * menu.h, termhooks.h: Include "systime.h", for Time.
18903 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18904 Don't assume that the difference between two unsigned long values
18905 can fit into an integer. At this point, we know button_down_time
18906 <= event->timestamp, so the difference must be nonnegative, so
18907 there's no need to cast the result if double-click-time is
18908 nonnegative, as it should be; check that it's nonnegative, just in
18909 case. This bug is triggered when events are more than 2**31 ms
18910 apart (about 25 days). (Bug#8664)
18912 * xselect.c (last_event_timestamp): Remove duplicate decl.
18913 (x_own_selection): Remove needless cast to unsigned long.
18915 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18916 that always fit in int. Use a sentinel instead of a counter, to
18917 avoid a temp and to allay GCC's concerns about possible int overflow.
18918 * frame.h (struct frame): Use int for menu_bar_items_used
18919 instead of EMACS_INT, since it always fits in int.
18921 * menu.c (grow_menu_items): Check for int overflow.
18923 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18925 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18926 Before, the code was not consistent. These values cannot exceed
18927 2**31 - 1 so there's no need to make them unsigned.
18928 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18929 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18930 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18932 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18934 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18935 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18936 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18937 presumably because the widths might not match.
18939 * window.c (size_window): Avoid needless test at loop start.
18941 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18943 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18945 2011-05-12 Drew Adams <drew.adams@oracle.com>
18947 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18949 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18951 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18952 `width' to `bar_area_x' and `bar_area_width', respectively.
18953 (x_scroll_run): Take account of fringe background extension.
18955 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18956 Rename local vars `left' and `width' to `bar_area_x' and
18957 `bar_area_width', respectively.
18958 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18959 background extension.
18961 2011-05-10 Jim Meyering <meyering@redhat.com>
18963 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18965 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18967 * image.c (Finit_image_library): Return t for built-in image types,
18968 like pbm and xbm. (Bug#8640)
18970 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18972 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18974 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18976 * w32console.c (Fset_screen_color): Doc fix.
18977 (Fget_screen_color): New function.
18978 (syms_of_ntterm): Defsubr it.
18980 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18981 unlink the temporary file if Fcall_process didn't create it in the
18983 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18984 child process will be redirected to a file specified with `:file'.
18985 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18986 cue to call_process_cleanup not to close that handle.
18988 2011-05-07 Ben Key <bkey76@gmail.com>
18990 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18991 one of two shell specific rules, either bootstrap-temacs-CMD or
18992 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18993 to the previous implementation of the bootstrap-temacs rule.
18994 The bootstrap-temacs-CMD rule is similar to the previous
18995 implementation of the bootstrap-temacs rule except that it
18996 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18999 These changes, along with some changes to nt/configure.bat,
19000 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19001 earlier fix to add support for --cflags and --ldflags options
19002 that include quotes so that it works whether make uses cmd or
19005 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19007 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19008 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19010 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19011 a string. Handle both cases.
19012 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19013 (Fdbus_register_method): Use Qinvalid_function.
19015 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19017 * makefile.w32-in: Update dependencies.
19018 (LISP_H): Add inttypes.h and stdin.h.
19019 (PROCESS_H): Add unistd.h.
19021 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19023 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19024 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19026 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19028 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19030 * term.c (vfatal): Remove stray call to va_end.
19031 It's not needed and the C Standard doesn't allow it here anyway.
19033 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19034 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19036 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19039 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19041 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19043 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19045 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19047 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19049 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19050 * charset.c (Fdefine_charset_internal): Don't initialize
19051 charset.code_space[15]. The value was garbage, on hosts with
19052 32-bit int (Bug#8600).
19054 * lread.c (read_integer): Be more consistent with string-to-number.
19055 Use string_to_number to do the actual conversion; this avoids
19056 rounding errors and fixes some other screwups. Without this fix,
19057 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19058 (digit_to_number): Move earlier, for benefit of read_integer.
19059 Return -1 if the digit is out of range for the base, -2 if it is
19060 not a digit in any supported base. (Bug#8602)
19062 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19064 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19065 to match comment at start of function. This also removes a
19066 GCC warning about overflow in a 32+64-bit port.
19068 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19070 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19071 Reported by Stefan Monnier in
19072 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19073 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19074 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19076 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19077 (EMACS_UINTPTR): Likewise, with uintptr_t.
19079 * lisp.h: Prefer 64-bit EMACS_INT if available.
19080 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19081 on 32-bit hosts that have 64-bit int, so that they can access
19083 However, temporarily disable this change unless the temporary
19084 symbol WIDE_EMACS_INT is defined.
19086 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19088 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19089 This removes an assumption that EMACS_INT and long are the same
19090 width as pointers. The assumption is true for Emacs porting targets
19091 now, but we want to make other targets possible.
19092 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19093 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19094 In the rest of the code, change types of integers that hold casted
19095 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19096 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19097 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19098 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19099 No need to cast type when ORing.
19100 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19101 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19102 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19103 assume EMACS_INT is the same width as char *.
19104 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19105 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19106 Remove no-longer-needed casts.
19107 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19108 (xg_tool_bar_help_callback, xg_make_tool_item):
19109 Use EMACS_INTPTR to hold an integer
19110 that will be cast to void *; this can avoid a GCC warning
19111 if EMACS_INT is not the same width as void *.
19112 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19113 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19114 (current_message_1, set_message_1):
19115 Use a local to convert to proper width without a cast.
19116 * xmenu.c (dialog_selection_callback): Likewise.
19118 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19119 Also, don't assume VALBITS / RAND_BITS is less than 5,
19120 and don't rely on undefined behavior when shifting a 1 left into
19122 * lisp.h (get_random): Change signature to match.
19124 * lread.c (hash_string): Use size_t, not int, for hash computation.
19125 Normally we prefer signed values; but hashing is special, because
19126 it's better to use unsigned division on hash table sizes so that
19127 the remainder is nonnegative. Also, size_t is the natural width
19128 for hashing into memory. The previous code used 'int', which doesn't
19129 retain enough info to hash well into very large tables.
19130 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19132 * dbusbind.c: Don't possibly lose pointer info when converting.
19133 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19134 Use XPNTR rather than XHASH, so that the high-order bits of
19135 the pointer aren't lost when converting through void *.
19137 * eval.c (Fautoload): Don't double-shift a pointer.
19139 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

19173 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19174 Remove unused parameter `fildes'.
19175 * process.c (read_process_output, send_process): Don't pass it.
19177 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19179 Fix previous change: the library cache is defined in w32.c.
19180 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19181 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

19223 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19224 instead of gnutls_record_check_pending.
19226 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19228 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19230 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19231 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19234 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19236 * xterm.c (x_set_frame_alpha): Do not set property on anything

19241 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19243 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19245 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

19266 which is like wait_for_termination, but allows keyboard
19269 * callproc.c (Fcall_process): Add (:file "file") as an option for
19271 (Fcall_process_region): Ditto.
19273 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19275 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19276 rather than `XVECTOR (FOO)->size'.
19278 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19279 inttypes.h, as a gnulib replacement is used if it not available in
19282 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19284 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19285 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19286 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19288 * coding.c (coding_alloc_by_realloc): Error out if destination
19289 will grow beyond MOST_POSITIVE_FIXNUM.
19290 (decode_coding_emacs_mule): Abort if there isn't enough place in
19291 charbuf for the composition carryover bytes. Reserve an extra
19292 space for up to 2 characters produced in a loop.

19294 charbuf for the composition carryover bytes.
19296 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19298 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19299 aborting when %lld or %lll format is passed.

19301 %llo or %llx format is passed. (Bug#8545)
19303 * window.c (window_scroll_line_based): Use a marker instead of
19304 simple variables to record original value of point. (Bug#7952)

19307 produced by %s or %c overflows available buffer space. (Bug#8545)
19309 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19311 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19323 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19324 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19326 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19328 * doprnt.c (doprnt): Don't return value smaller than the buffer
19329 size if the message was truncated. (Bug#8545).
19331 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19333 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

19340 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19342 * makefile.w32-in: Update dependencies.
19344 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19346 Improve `doprnt' and its usage. (Bug#8545)
19347 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19348 `format_end'. Remove support for %l as a conversion specifier.
19349 Don't use xrealloc. Improve diagnostics when the %l size modifier
19350 is used. Update the commentary.
19352 * eval.c (verror): Simplify calculation of size_t.
19354 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19357 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19359 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19362 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19364 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19365 This makes this file independent of the recent pseudovector change.
19367 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19369 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19371 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19372 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19373 Remove unused local.
19374 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19376 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19377 GCC 4.6.0 optimizes based on type-based alias analysis.
19378 For example, if b is of type struct buffer * and v of type struct
19379 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19380 != &v->size, and therefore "v->size = 1; b->size = 2; return
19381 v->size;" must therefore return 1. This assumption is incorrect
19382 for Emacs, since it type-puns struct Lisp_Vector * with many other
19383 types. To fix this problem, this patch adds a new type struct
19384 vectorlike_header that documents the constraints on layout of vectors
19385 and pseudovectors, and helps optimizing compilers not get fooled
19386 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19387 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19388 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19390 (XSETPVECTYPE): Rewrite in terms of new macro.
19391 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19392 This is a bit clearer, and further avoids the possibility of
19393 undesirable aliasing.
19394 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19395 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19396 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19397 since Lisp_Subr is a special case (no "next" field).
19398 (ASIZE): Now uses header.size rather than size.
19399 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19400 to avoid the hassle of writing XVECTOR (foo)->header.size.
19401 (struct vectorlike_header): New type.
19402 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19403 object, to help avoid aliasing.
19404 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19405 (SUBRP): Likewise, since Lisp_Subr is a special case.
19406 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19407 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19408 (struct Lisp_Hash_Table): Combine first two members into a single
19409 struct vectorlike_header member. All uses of "size" and "next" members
19410 changed to be "header.size" and "header.next".
19411 * buffer.h (struct buffer): Likewise.
19412 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19413 * frame.h (struct frame): Likewise.
19414 * process.h (struct Lisp_Process): Likewise.
19415 * termhooks.h (struct terminal): Likewise.
19416 * window.c (struct save_window_data, struct saved_window): Likewise.
19417 * window.h (struct window): Likewise.
19418 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19419 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19420 * buffer.c (init_buffer_once): Likewise.
19421 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19423 * process.c (Fformat_network_address): Use local var for size,
19426 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19428 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19429 * data.c (atof): Remove decl; no longer used or needed.
19430 (digit_to_number): Move to lread.c.
19431 (Fstring_to_number): Use new string_to_number function, to be
19432 consistent with how the Lisp reader treats infinities and NaNs.
19433 Do not assume that floating-point numbers represent EMACS_INT
19434 without losing information; this is not true on most 64-bit hosts.
19435 Avoid double-rounding errors, by insisting on integers when
19436 parsing non-base-10 numbers, as the documentation specifies.
19437 * lisp.h (string_to_number): New decl, replacing ...
19438 (isfloat_string): Remove.
19439 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19440 (read1): Do not accept +. and -. as integers; this
19441 appears to have been a coding error. Similarly, do not accept
19442 strings like +-1e0 as floating point numbers. Do not report
19443 overflow for integer overflows unless the base is not 10 which
19444 means we have no simple and reliable way to continue.
19445 Break out the floating-point parsing into a new
19446 function string_to_number, so that Fstring_to_number parses
19447 floating point numbers consistently with the Lisp reader.
19448 (digit_to_number): Move here from data.c. Make it static inline.
19449 (E_CHAR, EXP_INT): Remove, replacing with ...
19450 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19451 (string_to_number): New function, replacing isfloat_string.
19452 This function checks for valid syntax and produces the resulting
19453 Lisp float number too. Rework it so that string-to-number
19454 no longer mishandles examples like "1.0e+". Use strtoumax,
19455 so that overflow for non-base-10 numbers is reported only when
19456 there's no portable and simple way to convert to floating point.
19458 * textprop.c (set_text_properties_1): Rewrite for clarity,
19459 and to avoid GCC warning about integer overflow.
19461 * intervals.h (struct interval): Use EMACS_INT for members
19462 where EMACS_UINT might cause problems. See
19463 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19464 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19465 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19467 (offset_intervals): Tell GCC not to worry about length overflow
19468 when negating a negative length.
19470 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19471 (overrun_check_free): Likewise.
19473 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19474 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19477 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19478 (gnutls_make_error): Rename local to avoid shadowing.
19479 (gnutls_emacs_global_deinit): ifdef out; not used.
19480 (Fgnutls_boot): Use const for pointer to readonly storage.
19481 Comment out unused local. Fix pointer signedness problems.
19483 * lread.c (openp): Don't stuff size_t into an 'int'.
19484 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19485 about possible signed overflow.
19487 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19488 (GDK_KEY_g): Don't define if already defined.
19489 (xg_prepare_tooltip): Avoid pointer signedness problem.
19490 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19492 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19493 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19495 * xfns.c (Fx_window_property): Simplify a bit,
19496 to make a bit faster and to avoid GCC 4.6.0 warning.
19497 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19499 * fns.c (internal_equal): Don't assume size_t fits in int.
19501 * alloc.c (compact_small_strings): Tighten assertion a little.
19503 Replace pEd with more-general pI, and fix some printf arg casts.
19504 * lisp.h (pI): New macro, generalizing old pEd macro to other
19505 conversion specifiers. For example, use "...%"pI"d..." rather
19506 than "...%"pEd"...".
19507 (pEd): Remove. All uses replaced with similar uses of pI.
19508 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19509 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19510 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19511 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19512 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19513 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19514 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19516 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19517 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19518 * print.c (safe_debug_print, print_object): Likewise.
19519 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19521 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19522 avoiding the 0 flag, which is not portable.
19523 * process.c (Fmake_network_process): Use pI to avoid cast.
19524 * region-cache.c (pp_cache): Likewise.
19525 * xdisp.c (decode_mode_spec): Likewise.
19526 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19527 behavior on 64-bit hosts with printf arg.

19529 (x_stop_queuing_selection_requests): Likewise.
19530 (x_get_window_property): Don't truncate byte count to an 'int'
19533 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19534 here, since it parses constructs like leading '-' and spaces,
19535 which are not wanted; and it overflows with large numbers.
19536 Instead, simply match F[0-9]+, which is what is wanted anyway.
19538 * alloc.c: Remove unportable assumptions about struct layout.
19539 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19540 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19541 (allocate_vectorlike, make_pure_vector): Use the new macros,
19542 plus offsetof, to remove unportable assumptions about struct layout.
19543 These assumptions hold on all porting targets that I know of, but
19544 they are not guaranteed, they're easy to remove, and removing them
19545 makes further changes easier.
19547 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19548 This doesn't fix a bug but makes the code clearer.
19549 (string_overrun_cookie): Now const. Use initializers that
19550 don't formally overflow signed char, to avoid warnings.
19551 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19552 can cause Emacs to crash when string overrun checking is enabled.
19553 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19554 multiple of sizeof (EMACS_INT); it need not be, if
19555 alignof(EMACS_INT) < sizeof (EMACS_INT).
19556 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19558 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19585 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19587 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19588 "cast to pointer from integer of different size".
19590 Improve doprnt and its use in verror. (Bug#8545)
19591 * doprnt.c (doprnt): Document the set of format control sequences
19592 supported by the function. Use SAFE_ALLOCA instead of always
19595 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19596 is one byte too soon. Don't use xrealloc; instead xfree and
19599 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19601 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

19608 docstring. Start callback support.
19609 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19610 unless a fatal error occurred. Call gnutls_alert_send_appropriate

19714 codepoint of an invalid character, to avoid displaying a bogus
19717 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19718 `error', not SYMBOL_NAME itself.
19720 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19721 character arguments to `error'.
19723 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19724 to `error' in error message about FINAL_CHAR argument. Make sure
19725 FINAL_CHAR is a character, and use %c when it is passed as
19726 argument to `error'.
19728 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19730 * s/ms-w32.h (localtime): Redirect to sys_localtime.
19732 * w32.c: Include <time.h>.

19796 * dispextern.h (struct redisplay_interface): Rename param
19797 to avoid shadowing.
19798 * termhooks.h (struct terminal): Likewise.

19915 * nsfont.m: Fixed bugs in ns_get_family and
19916 ns_descriptor_to_entity that were caused by using free to
19917 deallocate memory blocks that were allocated by xmalloc (via
19918 xstrdup). This caused Emacs to crash when compiled with
19919 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19920 --enable-checking=xmallocoverrun). xfree is now used to
19921 deallocate these memory blocks.

19935 (emacs_read, emacs_write): Remove check for negative size, as the
19936 Emacs source code has been audited now.
19937 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
19938 (emacs_read, emacs_write): Use it.
19939 * process.c (send_process): Adjust to the new signatures of
19940 emacs_write and emacs_gnutls_write. Do not attempt to store
19941 a byte offset into an 'int'; it might overflow.

20404 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20405 (overrun_check_free): Protoize.
20407 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20409 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20410 since callers should never pass a negative size.
20411 Change the signature to match that of plain 'read' and 'write'; see
20412 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20413 * lisp.h: Update prototypes of emacs_write and emacs_read.
20415 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20417 * xdisp.c (redisplay_window): Don't try to determine the character
20418 position of the scroll margin if the window start point w->startp
20419 is outside the buffer's accessible region. (Bug#8468)
20421 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20423 Fix write-region and its subroutines for buffers > 2GB.
20424 * fileio.c (a_write, e_write): Modify declaration of arguments and
20425 local variables to support buffers larger than 2GB.
20426 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20428 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20429 argument, local variables, and return value.
20431 * lisp.h: Update prototypes of emacs_write and emacs_read.
20433 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20435 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20437 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20439 Fix more problems found by GCC 4.6.0's static checks.
20441 * xdisp.c (vmessage): Use a better test for character truncation.
20443 * charset.c (load_charset_map): <, not <=, for optimization,
20444 and to avoid potential problems with integer overflow.
20445 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20446 * casetab.c (set_identity, shuffle): Likewise.
20447 * editfns.c (Fformat): Likewise.
20448 * syntax.c (skip_chars): Likewise.
20450 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20451 This also lets GCC 4.6.0 generate slightly better loop code.
20453 * callint.c (Fcall_interactively): <, not <=, for optimization.
20454 (Fcall_interactively): Count the number of arguments produced,
20455 not the number of arguments given. This is simpler and lets GCC
20456 4.6.0 generate slightly better code.
20458 * ftfont.c: Distingish more carefully between FcChar8 and char.
20459 The previous code passed unsigned char * to a functions like
20460 strlen and xstrcasecmp that expect char *, which does not
20461 conform to the C standard.
20462 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20463 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20464 char * when the C standard requires it.
20466 * keyboard.c (read_char): Remove unused var.
20468 * eval.c: Port to Windows vsnprintf (Bug#8435).
20469 Include <limits.h>.
20470 (SIZE_MAX): Define if the headers do not.
20471 (verror): Do not give up if vsnprintf returns a negative count.
20472 Instead, grow the buffer. This ports to Windows vsnprintf, which
20473 does not conform to C99. Problem reported by Eli Zaretskii.
20474 Also, simplify the allocation scheme, by avoiding the need for
20475 calling realloc, and removing the ALLOCATED variable.
20477 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20479 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20480 But keep the doprint source code for now, as we might revamp it
20481 and use it again (Bug#8435).
20482 * lisp.h (doprnt): Remove.
20483 * Makefile.in (base_obj): Remove doprnt.o.
20484 * deps.mk (doprnt.o): Remove.
20486 error: Print 32- and 64-bit integers portably (Bug#8435).
20487 Without this change, on typical 64-bit hosts error ("...%d...", N)
20488 was used to print both 32- and 64-bit integers N, which relied on
20489 undefined behavior.
20490 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20491 * lisp.h (error, verror): Mark as printf-like functions.
20492 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20493 Report overflow in size calculations when allocating printf buffer.
20494 Do not truncate output string at its first null byte.
20495 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20496 Truncate the output at a character boundary, since vsnprintf does not
20498 * charset.c (check_iso_charset_parameter): Convert internal
20499 character to string before calling 'error', since %c now has the
20501 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20502 overflow when computing char to be passed to 'error'. Do not
20503 pass Lisp_Object to 'error'; pass the integer instead.
20504 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20505 formatted with plain %d.
20507 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20509 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20511 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20513 * xterm.c (x_catch_errors): Remove duplicate declaration.
20515 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20517 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20519 2011-04-10 Jim Meyering <meyering@redhat.com>
20521 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20522 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20523 return ssize_t not "int", and use size_t as the buffer length.
20524 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20525 * gnutls.h: Update declarations.
20526 * process.c (read_process_output): Use ssize_t, to match.
20527 (send_process): Likewise.
20529 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20531 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20533 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20535 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20536 Use unsigned char, to match FcChar8 type definition.
20538 * xterm.c (handle_one_xevent):
20539 * xmenu.c (create_and_show_popup_menu):
20540 * xselect.c (x_decline_selection_request)
20541 (x_reply_selection_request): Avoid type-punned deref of X events.
20543 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20545 Fix some uses of `int' instead of EMACS_INT.
20546 * search.c (string_match_1, fast_string_match)
20547 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20548 (scan_buffer, find_next_newline_no_quit)
20549 (find_before_next_newline, search_command, Freplace_match)
20550 (Fmatch_data): Make some `int' variables be EMACS_INT.
20552 * xdisp.c (display_count_lines): 3rd argument and return value now
20553 EMACS_INT. All callers changed.
20554 (pint2hrstr): Last argument is now EMACS_INT.
20556 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20557 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20558 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20559 (decode_coding_utf_16, decode_coding_emacs_mule)
20560 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20561 (decode_coding_ccl, decode_coding_charset)
20562 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20563 (decode_coding_iso_2022, decode_coding_emacs_mule)
20564 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20565 <char_offset, last_offset>: Declare EMACS_INT.
20566 (encode_coding_utf_8, encode_coding_utf_16)
20567 (encode_coding_emacs_mule, encode_invocation_designation)
20568 (encode_designation_at_bol, encode_coding_iso_2022)
20569 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20570 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20572 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20573 (encode_invocation_designation): Last argument P_NCHARS is now
20575 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20576 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20578 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20581 * ccl.c (Fccl_execute_on_string): Declare some variables
20584 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20586 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20588 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20590 * process.c (Fformat_network_address): Doc fix.
20592 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20594 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20596 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20598 * keyboard.c (read_char): Call Lisp function help-form-show,
20599 instead of using internal_with_output_to_temp_buffer.
20600 (Qhelp_form_show): New var.
20601 (syms_of_keyboard): Use DEFSYM macro.
20603 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20605 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20607 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20609 * process.c (Flist_processes): Remove to Lisp.
20610 (list_processes_1): Delete.

20614 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20616 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20618 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20620 Fix more problems found by GCC 4.6.0's static checks.

20624 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20626 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20628 * xdisp.c (vmessage): Mark as a printf-like function.
20630 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20632 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20634 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20635 printf-like functions.
20636 (tiff_load): Add casts to remove these marks before passing them
20637 to system-supplied API.
20639 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20641 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20642 This avoids several warnings with gcc -Wstrict-overflow.
20643 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20644 directly, rather than having caller test rule sign. This avoids
20645 some unnecessary tests.
20646 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20647 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20648 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20650 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20651 (xfont_open): Avoid unnecessary tests.
20653 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20655 * composite.h, composite.c (composition_gstring_put_cache):
20656 Use EMACS_INT, not int, for length.

20659 breaking out part of COMPOSITION_DECODE_RULE.
20660 (COMPOSITION_DECODE_RULE): Use it.

20662 by using the new macro.
20664 * textprop.c (set_text_properties_1): Change while to do-while,
20665 since the condition is always true at first.
20667 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20668 (interval_deletion_adjustment): Return unsigned value.
20671 * process.c (list_processes_1, create_pty, read_process_output):

20683 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20684 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20685 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20687 * print.c (print_error_message): Avoid int overflow.
20689 * font.c (font_list_entities): Redo for clarity,
20690 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20692 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20693 (font_score): Avoid potential overflow in diff calculation.
20695 * fns.c (substring_both): Remove var that is set but not used.
20696 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20698 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20700 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20701 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20702 can always succeed if overflow has undefined behavior.
20704 * search.c (boyer_moore, wordify): Remove vars set but not used.
20705 (wordify): Omit three unnecessary tests.
20707 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20708 All callers changed. This avoids the need for an unused var.
20710 * casefiddle.c (casify_region): Remove var that is set but not used.
20712 * dired.c (file_name_completion): Remove var that is set but not used.
20714 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20716 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20717 (Finsert_file_contents): Remove unnecessary code checking fd.
20719 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20720 Check for integer overflow on size calculations.
20722 * buffer.c (Fprevious_overlay_change): Remove var that is set
20725 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20726 Remove vars that are set but not used.
20727 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20728 (timer_check_2): Mark vars as initialized.
20730 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20732 * image.c (lookup_image): Remove var that is set but not used.
20733 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20735 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20736 that are set but not used.
20738 * xfns.c (make_invisible_cursor): Don't return garbage
20739 if XCreateBitmapFromData fails (Bug#8410).
20741 * xselect.c (x_get_local_selection, x_handle_property_notify):
20742 Remove vars that are set but not used.
20744 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

20754 (map_tty_color) [!defined MSDOS]: Likewise.
20756 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20758 * coding.c: Remove vars that are set but not used.
20759 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20760 All callers changed.
20761 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20762 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20763 (decode_coding_charset): Remove vars that are set but not used.
20765 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20766 that is set but not used.
20768 * print.c (print_object): Remove var that is set but not used.
20770 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20771 The gnulib version avoids calling malloc in the usual case,
20772 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20773 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20774 * filelock.c (current_lock_owner): Likewise.
20775 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

20778 (emacs_readlink): New function.
20779 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20780 ../lib/careadlinkat.h.
20782 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20784 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20785 first non-nil return value).

20789 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20790 if not defined (Bug#8403).

20794 * xdisp.c (display_count_lines): Remove parameter `start',
20795 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

20799 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20800 and thereabouts. All callers changed.
20801 (get_per_char_metric): Remove parameter `f', unused since
20802 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20806 do not dereference NULL upon failed strdup
20807 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20808 (ns_get_family): Likewise.
20810 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

20860 but without exporting it to Lisp.
20862 * doc.c (Fdocumentation, store_function_docstring):
20863 * data.c (Finteractive_form): Handle closures.
20865 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20868 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20870 (exec_byte_code): New function extracted from Fbyte_code to handle new
20871 calling convention for byte-code-functions. Add new byte-codes.
20873 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20875 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20877 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20879 * xdisp.c (redisplay_internal): Fix prototype.
20881 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20883 * xdisp.c (SCROLL_LIMIT): New macro.
20884 (try_scrolling): Use it when setting scroll_limit.
20885 Limit scrolling to 100 screen lines.
20886 (redisplay_window): Even when falling back on "recentering",
20887 position point in the window according to scroll-conservatively,
20888 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20890 (try_scrolling): When point is above the window, allow searching
20891 as far as scroll_max, or one screenful, to compute vertical
20892 distance from PT to the scroll margin position. This prevents
20893 try_scrolling from unnecessarily failing when
20894 scroll-conservatively is set to a value slightly larger than the
20895 window height. Clean up the case of PT below the margin at bottom
20896 of window: scroll_max can no longer be INT_MAX. When aggressive
20897 scrolling is in use, don't let point enter the opposite scroll
20898 margin as result of the scroll.
20899 (syms_of_xdisp) <scroll-conservatively>: Document the
20900 threshold of 100 lines for never-recentering scrolling.
20902 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20904 * dispextern.h (move_it_by_lines):
20905 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20906 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20907 (message_log_check_duplicate): Remove parameters `prev_bol' and
20908 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20909 (redisplay_internal): Remove parameter `preserve_echo_area',
20910 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20912 * indent.c (Fvertical_motion):
20913 * window.c (window_scroll_pixel_based, Frecenter):
20914 Don't pass `need_y_p' to `move_it_by_lines'.
20916 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20918 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20919 steal a few bits to be more compact.
20920 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20921 Remove unneeded casts.
20923 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20925 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20927 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20928 binding" message (bug#7967).
20930 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20932 Fix more problems found by GCC 4.6.0's static checks.
20934 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20935 Remove unused local var.
20937 * editfns.c (Fmessage_box): Remove unused local var.
20939 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20940 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20941 Omit unused local vars.
20942 * window.c (shrink_windows): Omit unused local var.
20943 * menu.c (digest_single_submenu): Omit unused local var.
20944 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20945 Omit unused local var.
20947 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20948 Don't assume string length fits in int.
20949 (keyremap_step, read_key_sequence): Use size_t for sizes.
20950 (read_key_sequence): Don't check last_real_key_start redundantly.
20952 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20953 instead of alloca (Bug#8344).
20955 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20956 (Fbacktrace_frame): Don't assume nframes fits in int.
20958 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20960 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20963 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20965 * cm.c (calccost): Turn while-do into do-while, for clarity.
20967 * keyboard.c (syms_of_keyboard): Use the same style as later
20968 in this function when indexing through an array. This also
20969 works around GCC bug 48267.
20971 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20973 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20975 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20976 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20978 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20979 This avoids undefined behavior on integer overflow, and is a bit
20980 more convenient anyway since it is compared to a size_t variable.
20982 Variadic C functions now count arguments with size_t, not int.
20983 This avoids an unnecessary limitation on 64-bit machines, which
20984 caused (substring ...) to crash on large vectors (Bug#8344).
20985 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20986 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20987 All variadic functions and their callers changed accordingly.
20988 (struct gcpro.nvars): Now size_t, not int. All uses changed.

20990 * editfns.c (general_insert_function): Likewise.
20991 * eval.c (struct backtrace.nargs, interactive_p)
20992 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20993 (funcall_lambda, mark_backtrace): Likewise.
20994 * fns.c (concat): Likewise.
20995 * frame.c (x_set_frame_parameters): Likewise.
20996 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20997 0 if not found, not -1. All callers changed.
20999 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21000 (stack_copy_size): Now size_t, not int.
21001 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21003 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21005 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21006 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21007 All callers changed.
21009 * lisp.h (multibyte_char_to_unibyte):
21010 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21011 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21012 * character.h (CHAR_TO_BYTE8):
21013 * cmds.c (internal_self_insert):
21014 * editfns.c (general_insert_function):
21015 * keymap.c (push_key_description):
21016 * search.c (Freplace_match):
21017 * xdisp.c (message_dolog, set_message_1): All callers changed.
21019 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21021 * keyboard.c (safe_run_hook_funcall): New function.
21022 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21023 don't set the hook to nil, but remove the offending function instead.
21024 (Qcommand_hook_internal): Remove, unused.
21025 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21026 Vcommand_hook_internal.
21028 * eval.c (enum run_hooks_condition): Remove.
21029 (funcall_nil, funcall_not): New functions.
21030 (run_hook_with_args): Call each function through a `funcall' argument.
21031 Remove `cond' argument, now redundant.
21032 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21033 (Frun_hook_with_args_until_failure): Adjust accordingly.
21034 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21036 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21038 * dispextern.h (string_buffer_position): Remove declaration.
21040 * print.c (strout): Remove parameter `multibyte', unused since
21041 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21043 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21044 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21045 All callers changed.
21047 * w32.c (_wsa_errlist): Use braces for struct initializers.
21049 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21050 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21051 All callers changed.
21052 (string_buffer_position): Likewise. Also, make static (it's never
21053 used outside xdisp.c).
21054 (cursor_row_p): Remove parameter `w', unused since
21055 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21057 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21058 All callers changed.
21060 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21062 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21068 (ns_update_auto_hide_menu_bar): New functions.
21069 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

21073 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21075 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21077 * nsmenu.m (runDialogAt): Remove argument to timer_check.
21079 2011-03-27 Glenn Morris <rgm@gnu.org>
21081 * syssignal.h: Replace RETSIGTYPE with void.
21082 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
21083 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
21084 Replace SIGTYPE with void everywhere.
21085 * s/usg5-4-common.h (SIGTYPE): Remove definition.
21086 * s/template.h (SIGTYPE): Remove commented out definition.
21088 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21090 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21091 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21093 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21095 * w32.c (read_unc_volume): Use parameter `henum', instead of
21096 global variable `wget_enum_handle'.
21098 * keymap.c (describe_vector): Remove parameters `indices' and
21099 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21102 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21104 * keyboard.c (timer_check): Remove parameter `do_it_now',
21105 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
21106 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
21107 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
21109 * keyboard.c (read_char):
21110 * w32menu.c (w32_menu_display_help):
21111 * xmenu.c (show_help_event, menu_help_callback):
21112 Adjust calls to `show_help_echo'.
21114 * gtkutil.c (xg_maybe_add_timer):
21115 * keyboard.c (readable_events):
21116 * process.c (wait_reading_process_output):
21117 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21119 * insdel.c (adjust_markers_gap_motion):
21120 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
21121 (gap_left, gap_right): Don't call it.
21123 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

21167 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
21169 * w32term.c (x_set_glyph_string_clipping):
21170 Don't pass uninitialized region to CombineRgn.
21172 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
21174 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
21175 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
21176 (Fx_close_connection): Remove unused variable `i'.
21178 * w32font.c (w32font_draw): Return number of glyphs.

21192 (uniscribe_font_driver): Add missing initializers.
21194 2011-03-23 Julien Danjou <julien@danjou.info>
21196 * term.c (Fsuspend_tty, Fresume_tty):
21197 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21198 * window.c (temp_output_buffer_show):
21199 * insdel.c (signal_before_change):
21200 * frame.c (Fhandle_switch_frame):
21201 * fileio.c (Fdo_auto_save):

21203 * editfns.c (save_excursion_restore):
21204 * cmds.c (internal_self_insert):
21205 * callint.c (Fcall_interactively):
21206 * buffer.c (Fkill_all_local_variables):
21207 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21209 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21210 unconditionally since it does the check itself.
21212 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21214 Fix more problems found by GCC 4.5.2's static checks.
21216 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21217 the first time through the loop, since we know p0 < p1 then.
21218 This also avoids a gcc -Wstrict-overflow warning.
21220 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21221 leading to a memory leak, possible in functions like
21222 load_charset_map_from_file that can allocate an unbounded number
21223 of objects (Bug#8318).
21225 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21226 that could (at least in theory) be that large.
21228 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21229 This is less likely to overflow, and avoids undefined behavior if
21230 overflow does occur. All callers changed. Use strtoul to scan
21231 for the unsigned long integer.
21232 (pint2hrstr): Simplify and tune code slightly.
21233 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21235 * scroll.c (do_scrolling): Work around GCC bug 48228.
21236 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21238 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21239 This also avoids a warning with gcc -Wstrict-overflow.
21240 (validate_x_resource_name): Simplify count usage.
21241 This also avoids a warning with gcc -Wstrict-overflow.
21243 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21246 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21248 * process.c (Fmake_network_process): Use socklen_t, not int,
21249 where POSIX says socklen_t is required in portable programs.
21250 This fixes a porting bug on hosts like 64-bit HP-UX, where
21251 socklen_t is wider than int (Bug#8277).
21252 (Fmake_network_process, server_accept_connection):
21253 (wait_reading_process_output, read_process_output):
21256 * process.c: Rename or move locals to avoid shadowing.
21257 (list_processes_1, Fmake_network_process):
21258 (read_process_output_error_handler, exec_sentinel_error_handler):
21259 Rename or move locals.
21260 (Fmake_network_process): Define label "retry_connect" only if needed.
21261 (Fnetwork_interface_info): Fix pointer signedness.
21262 (process_send_signal): Add cast to avoid pointer signedness problem.
21263 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21264 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21266 Make tparam.h and terminfo.c consistent.
21267 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21268 Include tparam.h instead, since it declares them.
21269 * cm.h (PC): Remove extern decl; tparam.h now does this.
21270 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21271 * terminfo.c: Include tparam.h, to check interfaces.
21272 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21273 (tparam): Adjust signature to match interface in tparam.h;
21274 this removes some undefined behavior. Check that outstring and len
21275 are zero, which they always are with Emacs.
21276 * tparam.h (PC, BC, UP): New extern decls.
21278 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21279 (xftfont_open): Rename locals to avoid shadowing.
21281 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21282 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21283 (OTF_TAG_SYM): Omit macro if not needed.
21284 (ftfont_list): Remove unused local.
21285 (get_adstyle_property, ftfont_pattern_entity):
21286 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21287 Rename locals to avoid shadowing.
21289 * xfont.c (xfont_list_family): Mark var as initialized.
21291 * xml.c (make_dom): Now static.
21293 * composite.c (composition_compute_stop_pos): Rename local to

21330 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21332 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21333 This should get cleaned up, so that child_setup has the
21334 same signature on all platforms.

21498 (Fmemory_limit): Cast sbrk's returned value to char *.
21500 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21505 Use functions, not macros, for up- and down-casing (Bug#8254).
21506 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21507 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21508 to use the following functions instead of these macros.
21509 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21510 EMACS_INT, since callers assume the returned value fits in int.
21511 (upcase1): Likewise, for UPCASE_TABLE.
21512 (uppercasep, lowercasep, upcase): New static inline functions.
21513 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21523 (regex_compile, re_match_2_internal): Mark locals as initialized.
21524 (RETALLOC_IF): Define only if needed.
21525 (WORDCHAR_P): Likewise. This one is never needed, but is used
21526 only in a comment talking about a compiler bug, so put inside
21527 the #if 0 of that comment.
21528 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21529 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21555 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21556 New macros, so that the caller can use some names other than
21557 gcpro1, gcpro2, etc.
21558 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21560 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21561 argument, for consistency with GCPRO2_VAR, etc: it is now the
21562 prefix of the variable, not the variable itself. All uses
21564 * dired.c (directory_files_internal, file_name_completion):
21565 Rename locals to avoid shadowing.
21567 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21568 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21569 dired.c's scmp function, had undefined behavior.
21570 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21571 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21572 * buffer.h: ... to here, because these macros use current_buffer,
21573 and the new implementation with inline functions needs to have
21574 current_buffer in scope now, rather than later when the macros
21576 (downcase, upcase1): New static inline functions.
21577 (DOWNCASE, UPCASE1): Reimplement using these functions.
21578 This avoids undefined behavior in expressions like
21579 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21580 from race conditions in accessing the global variables
21581 case_temp1 and case_temp2.
21582 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21583 * lisp.h (case_temp1, case_temp2): Remove their decls.
21584 * character.h (ASCII_CHAR_P): Move from here ...
21585 * lisp.h: ... to here, so that the inline functions mentioned
21586 above can use them.
21588 * dired.c (directory_files_internal_unwind): Now static.
21590 * fileio.c (file_name_as_directory, directory_file_name):

21593 (file_name_as_directory): Use const pointers when appropriate.
21594 (Fexpand_file_name): Likewise. In particular, newdir might
21595 point at constant storage, so make it a const pointer.
21596 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21597 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21599 (Fset_file_times, Finsert_file_contents, auto_save_error):

21604 to avoid shadowing.
21606 * marker.c (bytepos_to_charpos): Remove; unused.
21608 * lisp.h (verify_bytepos, count_markers): New decls,
21609 so that gcc does not warn that these functions aren't declared.
21611 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21612 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21613 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21614 (copy_text): Remove unused local var.
21616 * filelock.c (within_one_second): Now static.
21617 (lock_file_1): Rename local to avoid shadowing.
21619 * buffer.c (fix_overlays_before): Mark locals as initialized.
21620 (fix_start_end_in_overlays): Likewise. This function should be
21621 simplified by using pointers-to-pointers, but that's a different
21623 (switch_to_buffer_1): Now static.
21624 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21625 (report_overlay_modification): Rename locals to avoid shadowing.
21627 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21628 Fix pointer signedness issue.
21629 (sys_subshell): Mark local as volatile if checking for lint,
21630 to suppress a gcc -Wclobbered warning that does not seem to be right.
21631 (MAXPATHLEN): Define only if needed.
21633 * process.c (serial_open, serial_configure): Move decls from here ...
21634 * systty.h: ... to here, so that they can be checked.
21636 * fns.c (get_random, seed_random): Move extern decls from here ...
21637 * lisp.h: ... to here, so that they can be checked.
21639 * sysdep.c (reset_io): Now static.

21645 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21646 (DENSE_TABLE_SIZE): Remove; unused.
21647 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21648 (describe_map_tree):
21649 Rename locals to avoid shadowing.
21651 * keyboard.c: Declare functions static if they are not used elsewhere.
