1 2013-02-09 Eli Zaretskii <eliz@gnu.org>
3 * callproc.c (Fcall_process_region): Make sure the XXXXXX part of
4 the temporary file pattern is not downcased even when
5 w32-downcase-file-names is non-nil. (Bug#13661)

23 (scan_sexps_forward): Record from_byte and avoid redundant
24 character to byte position calculation ...
25 (Fparse_partial_sexp): ... here. Break too long line.
27 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
29 * lisp.h (make_uninit_vector): New function.
30 * alloc.c (Fvector, Fmake_byte_code):
31 * ccl.c (Fregister_ccl_program):
32 * charset.c (Fdefine_charset_internal, define_charset_internal):
33 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):

42 * window.c (Fcurrent_window_configuration):
43 * xfaces.c (Fx_family_fonts):
44 * xselect.c (selection_data_to_lisp_data): Use it.
46 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
48 * coding.c (Fdefine_coding_system_internal): Use AREF where
49 argument is known to be a vector.
50 * fns.c (Flocale_info): Likewise for ASET.
51 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
52 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
54 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
56 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
59 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
60 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
61 updateCollectionBehaviour.
63 * nsterm.m (NEW_STYLE_FS): Remove.
64 (ns_last_use_native_fullscreen): New variable.
65 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
66 (x_set_window_size): Do not take title bar and tool bar into account
67 if isFullscreen returns YES.
68 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
69 (check_native_fs): New function.
70 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
71 (ns_term_init): Remove NEW_STYLE_FS.

84 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
85 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
86 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
87 (syms_of_nsterm): Add ns-use-native-fullscreen.
89 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
91 * fileio.c (Qchoose_write_coding_system): Now static.
93 2013-02-04 Eli Zaretskii <eliz@gnu.org>
95 * xdisp.c (window_buffer_changed): region_showing can be negative,
96 which still means region is being displayed.
97 (redisplay_internal): Resurrect code that forced redisplay of the
98 whole window when showing region and the mark has changed. Record
99 the new mark position to allow redisplay optimizations.
100 (display_line): If it->region_beg_charpos is non-zero, set the
101 window's region_showing member to -1. (Bug#13623) (Bug#13626)
103 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
104 not bitfield of 1 bit.
106 2013-02-03 Daniel Colascione <dancol@dancol.org>
108 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
109 daemon mode works on cygw32 when Emacs is installed and not just
112 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
114 Avoid file time stamp bug on MS-Windows (Bug#13149).
115 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
116 as FAT32 doesn't update time stamps when truncating them.
117 Also, check that a file time stamp is not a multiple of 100 ns;
118 this should catch all instances of the problem on MS-Windows,
119 as its native file system resolution is 100 ns or worse, and
120 checking for a non-multiple of 100 ns should impose only a small
121 overhead on systems with ns resolution.
123 2013-02-02 Eli Zaretskii <eliz@gnu.org>
125 Avoid encoding file names on MS-Windows when they need to be run
126 through dostounix_filename.
127 * w32.c (normalize_filename): Accept an additional argument
128 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
129 downcase it even if w32-downcase-file-names is non-nil.
130 (dostounix_filename): Accept an additional argument MULTIBYTE and
131 pass it to normalize_filename.
132 (emacs_root_dir): Adjust.
134 * msdos.h (dostounix_filename): Adjust prototype.
136 * w32.h (dostounix_filename): Adjust prototype.
138 * msdos.c (dostounix_filename): Accept an additional argument and
140 (init_environment): Adjust callers of dostounix_filename.
142 * fileio.c (Ffile_name_directory, file_name_as_directory)
143 (directory_file_name, Fexpand_file_name)
144 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
146 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
148 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
149 variables, as egetenv is case-insensitive for DOS_NT.
151 * dired.c (file_name_completion): Don't call Fdirectory_file_name
152 with an encoded file name.
154 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
155 calls to dostounix_filename.
157 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
159 * unexw32.c (unexec): Adjust call to dostounix_filename.
161 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
163 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
166 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
169 * callproc.c (Fcall_process): Make sure program name in PATH and
170 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
171 is passed to exec/spawnve, which fails unless the file-name
174 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
175 even if w32-quote-process-args is nil.
177 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
179 Fix timestamp bug when write-region appends nothing (Bug#13149).
180 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
181 the file's time stamp doesn't change if Emacs happens to write nothing
182 to the file, and on a buggy file system this could cause Emacs to
183 incorrectly infer that the file system doesn't have the bug.
184 Avoid this problem by inhibiting the inference in this case.
186 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
188 * window.h (struct window): Convert base_line_number, base_line_pos
189 and column_number_displayed members from Lisp_Object to ptrdiff_t.
190 Convert region_showing member from Lisp_Object to bitfield.
191 Remove sequence_number member. Adjust comments.
192 * window.c (sequence_number): Remove.
193 (make_window): Initialize column_number_displayed.
194 * print.c (print_object): Follow the printed representation of
195 frames and print window pointer to distinguish between windows.
196 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
197 * xdisp.c (wset_base_line_number, wset_base_line_pos)
198 (wset_column_number_displayed, wset_region_showing): Remove.
199 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
200 (try_scrolling, try_cursor_movement, redisplay_window)
201 (try_window_reusing_current_matrix, try_window_id, display_line)
202 (display_mode_lines, decode_mode_spec): Adjust users.
203 * .gdbinit (pwinx): Do not print sequence_number.
205 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
207 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
208 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
209 * dired.c: Include <fcntl.h>.
210 (open_directory): New function, which uses open and fdopendir
211 rather than opendir. DOS_NT platforms still use opendir, though.
212 (directory_files_internal, file_name_completion): Use it.
213 (file_attributes): New function, with most of the old Ffile_attributes.
214 (directory_files_internal, Ffile_attributes): Use it.
215 (file_attributes, file_name_completion_stat): First arg is now fd,
216 not dir name. All uses changed. Use fstatat rather than lstat +
218 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
219 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
220 (emacs_readlinkat): New function, with much of the old
221 Ffile_symlink_p, but with an fd argument for speed.
222 It uses readlinkat rather than careadlinkatcwd, so that it
223 need not assume the working directory.
224 (Ffile_symlink_p): Use it.
225 * filelock.c (current_lock_owner): Use emacs_readlinkat
226 rather than emacs_readlink.
227 * lisp.h (emacs_readlinkat): New decl.
228 (READLINK_BUFSIZE, emacs_readlink): Remove.
229 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
230 (emacs_norealloc_allocator, emacs_readlink): Remove.
231 This stuff is moved to fileio.c.
232 * w32.c (fstatat, readlinkat): New functions.
233 (careadlinkat): Don't check that fd == AT_FDCWD.
234 (careadlinkatcwd): Remove; no longer needed.
236 2013-01-31 Glenn Morris <rgm@gnu.org>
238 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
239 (Fwrite_region): Update for new choose_write_coding_system args.
240 Move the last piece of choose_write_coding_system here. (Bug#13522)
241 (syms_of_fileio): Add choose-write-coding-system.
243 2013-01-30 Eli Zaretskii <eliz@gnu.org>
245 * w32.c (sys_open): Zero out the flags for the new file descriptor.
246 (sys_close): Zero out the flags for the file descriptor before
247 closing it. (Bug#13546)
249 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
250 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
251 CharNextExA and CharPrevExA to iterate over file names encoded in
254 * w32.c (w32_get_long_filename, init_environment, readlink):
255 Support file names encoded in DBCS codepages.
256 (readlink): Use the current file-name-coding-system, not the ANSI
257 codepage, to decode and handle targets of symlinks.
259 2013-01-28 Eli Zaretskii <eliz@gnu.org>
261 * w32.c (opendir): Now accepts a 'const char *'.
263 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
265 Remove obsolete redisplay code. See the discussion at
266 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
267 * dispnew.c (preemption_period, preemption_next_check): Remove.
268 (Vredisplay_preemption_period): Likewise.
269 (update_frame, update_single_window, update_window, update_frame_1):
270 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
271 used, following the 2012-06-22 change.
273 2013-01-25 Eli Zaretskii <eliz@gnu.org>
275 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
277 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
279 * font.c (num_fonts): Remove the leftover from old
280 debugging code. Adjust comment style here and there.
281 * insdel.c (insert_1): Remove.
282 * lisp.h (insert_1): Remove prototype.
283 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
285 2013-01-25 Eli Zaretskii <eliz@gnu.org>
287 * w32.c (max_filename_mbslen): New function.
288 (normalize_filename, readdir): Use it to detect locales where ANSI
289 encoding of file names uses a double-byte character set (DBCS).
290 If a DBCS encoding is used, advance by characters using
291 CharNextExA, instead of incrementing a 'char *' pointer. Use
292 _mbslwr instead of _strlwr. (Bug#13515)
294 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
295 request of memory reservation to 1.7GB. (Bug#13065)
297 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
299 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
300 at check_extra_latin label. (Bug#13505)
302 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
304 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
305 Avoid redundant calls to strlen.
307 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
309 Drop async_visible and async_iconified fields of struct frame.
310 This is possible because async input is gone; for details, see
311 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
312 * frame.h (struct frame): Remove async_visible and async_iconified
313 members, convert garbaged to unsigned bitfield. Adjust comments.
314 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
315 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
316 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
317 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
318 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
320 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
321 properly. Likewise for obscured.
323 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
326 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
328 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
330 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
331 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
333 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
335 * xdisp.c (message2, message2_nolog): Remove functions.
336 (message3, message3_nolog): Extract nbytes and multibyteness directly
337 from the string. Change all callers.
338 (message3_nolog): Don't set message_enable_multibyte since set_message
339 will reset it anyway.
340 (message1, message1_nolog): Use message3.
341 (vmessage): Use a stack allocated buffer rather than f->message_buf.
342 (with_echo_area_buffer): Remove last two arguments. Update all callers.
343 (set_message): Drop all but the second arg, which has to be a string.
344 (set_message_1): Simplify now that we know that a1 is NULL and the
345 second arg is a string.
346 * frame.h (struct frame): Remove `message_buf' field.
347 Use glyphs_initialized_p instead.
348 (FRAME_MESSAGE_BUF): Remove macro.
349 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
350 * lisp.h (message2, message2_nolog): Remove declarations.
351 (message3, message3_nolog): Update declarations.
352 * keyboard.c (read_char_minibuf_menu_text)
353 (read_char_minibuf_menu_width): Remove vars.
354 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
355 to correctly handle multibyte strings.
356 * frame.c (delete_frame): Don't free message_buf any more.
357 * editfns.c (message_text, message_length): Remove vars.
358 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
359 * fileio.c (auto_save_error): Use message3 instead of message2.
360 * dispnew.c (adjust_frame_message_buffer): Remove function.
362 2013-01-23 Eli Zaretskii <eliz@gnu.org>
364 * w32term.c (w32fullscreen_hook): Account correctly for the screen
365 real estate used for the tool bar and the menu bar.
367 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
369 * insdel.c (prepare_to_modify_buffer): Force redisplay if
370 hidden buffer is prepared to modification (Bug#13164).
372 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
374 * window.h (struct window): Change window_end_valid member from
375 Lisp_Object to a bitfield. Adjust comments.
376 (wset_window_end_valid): Remove.
377 * window.c (adjust_window_count): Clear window_end_valid.
378 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
379 (Fwindow_line_height, set_window_buffer, Frecenter)
380 (Fsplit_window_internal, Fdelete_other_windows_internal)
381 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
382 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
383 * xdisp.c (check_window_end, reconsider_clip_changes)
384 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
385 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
386 (find_first_unchanged_at_end_row, try_window_id): Likewise.
388 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
390 * xdisp.c (mark_window_display_accurate): Simplify the loop
391 assuming that the only one of vchild, hchild or buffer window
392 slots is non-nil. Call mark_window_display_accurate_1 for
393 the leaf windows only.
394 (mark_window_display_accurate_1): Always assume leaf window.
397 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
399 * emacs.c (Qkill_emacs_hook): Now static.
401 * fileio.c (Finsert_file_contents): Simplify.
402 Remove unnecessary assignments and tests.
404 2013-01-21 Eli Zaretskii <eliz@gnu.org>
406 * w32.c (acl_set_file): Don't test for errors unless
407 set_file_security returns FALSE. Avoids spurious errors when
410 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
412 * fileio.c (Finsert_file_contents): Revert code introduced at
413 2013-01-18 in favor of the simpler and generally better fix.
414 Save stack space by removing 'buffer' and reusing 'read_buf'
417 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
419 * lisp.h (eabs): Define unconditionally (Bug#13419).
420 The old "#if !defined (eabs)" was an unnecessary revenant of back
421 when this macro was called "abs". Document 'eabs' better.
423 2013-01-19 Glenn Morris <rgm@gnu.org>
425 * fns.c (Frandom): Doc fix.
427 2013-01-19 Eli Zaretskii <eliz@gnu.org>
429 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
430 segfault when there are lots of overlays.
432 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
433 when there are lots of overlays. See
434 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
435 for the details and a way to reproduce.
437 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
439 * fileio.c: Use O_APPEND to append.
440 This corresponds better to the natural interpretation of "append",
441 and avoids the need to open the output file twice, or to invoke
442 lseek when APPEND is neither nil nor a number.
443 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
444 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
445 file possibly twice, and lseeking to its end; this avoids the
446 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
447 at the same time: the combination is never needed and apparently
448 it doesn't work with DOS_NT.
450 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
451 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
453 Allow floating-point file offsets.
454 Problem reported by Vitalie Spinu in
455 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
456 * fileio.c (emacs_lseek): Remove.
457 (file_offset): New function.
458 (Finsert_file_contents, Fwrite_region): Use it.
460 2013-01-19 Chong Yidong <cyd@gnu.org>
462 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
463 aborting on Fsignal (Bug#13289).
465 2013-01-19 Eli Zaretskii <eliz@gnu.org>
467 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
468 set_file_security as failure due to insufficient privileges.
469 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
470 (fstat): Return owner and group like 'stat' and 'lstat' do.
472 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
474 Work around bug in CIFS and vboxsf file systems (Bug#13149).
475 The bug was observed on Ubuntu operating inside a virtual machine,
476 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
477 The workaround introduces a race condition on non-buggy hosts,
478 but it's an unlikely race and anyway there's a nearly identical
479 nearby race that can't be fixed.

956 (Fset_buffer_modified_p): Use buffer_window_count to check
957 whether the buffer is displayed in some window.
958 * xdisp.c (message_dolog): Likewise.
960 2012-12-23 Eli Zaretskii <eliz@gnu.org>
962 * w32.c (acl_set_file): If setting the file security descriptor
963 fails, and the new DACL is identical to the existing one, silently
964 return success. This fixes problems for users backing up their
965 own files without having the necessary privileges for setting
966 security descriptors.
968 * w32proc.c (reader_thread): Do not index fd_info[] with negative
970 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
971 after WaitForSingleObject returns normally. This expedites reader
972 thread shutdown when delete_child triggers it.
973 (reap_subprocess): More accurate commentary for why we call
974 delete_child only when cp->fd is negative.
976 * w32.c (sys_close): Do not call delete_child on a subprocess
977 whose handle is not yet closed. Instead, set its file descriptor
978 to a negative value, so that reap_subprocess will call
979 delete_child on that subprocess when its SIGCHLD arrives.
980 This avoids closing handles used for communications between sys_select
981 and reader_thread, which doesn't give sys_select a chance to
982 notice that the process exited and invoke the SIGCHLD handler for
985 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
987 * nsfns.m (Fns_do_applescript): Run event loop until script has
988 been executed (Bug#12969).
989 (ns_run_ascript): Chech as_script for nil, set to nil after
992 2012-12-22 Martin Rudalics <rudalics@gmx.at>
994 * window.c (Fselect_window): Reword doc-string (Bug#13248).
996 2012-12-22 Eli Zaretskii <eliz@gnu.org>
998 * w32term.c (w32fullscreen_hook): New function.
999 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1001 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1003 * fileio.c (Finsert_file_contents): Doc fix.
1005 * w32proc.c (new_child, delete_child, find_child_pid): For a
1006 subprocess, consider its slot being in use as long as its process
1007 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1008 slot when a new process is started immediately after killing
1009 another one, without waiting enough time for the first process to
1010 be reaped and resources allocated for it be orderly freed.
1012 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1014 2012-12-21 Chong Yidong <cyd@gnu.org>
1016 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1018 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1020 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1022 * w32.c (get_name_and_id): Always pass NULL as the first argument
1023 of lookup_account_sid. Avoids crashes with UNC file names that
1024 refer to DFS domains, not to specific machine names. (Bug#12621)
1025 Remove now unused argument FNAME; all callers changed.
1026 (get_file_owner_and_group): Remove now unused argument FNAME; all
1029 2012-12-21 Chong Yidong <cyd@gnu.org>
1031 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1032 error for invalid chars, don't check for a nil return value.
1034 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1036 Avoid calls to CHAR_TO_BYTE if byte position is known.
1037 * editfns.c (make_buffer_string_both): Use move_gap_both.
1038 (Fbuffer_string): Use make_buffer_string_both.
1039 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1041 (buf_bytepos_to_charpos): Likewise.
1042 (charpos_to_bytepos): Remove.
1043 * fileio.c (Finsert_file_contents): Use move_gap_both.
1044 * search.c (Freplace_match): Likewise.
1045 * process.c (process_send_region): Likewise. Use convenient
1046 names for byte positions.
1047 * lisp.h (charpos_to_bytepos): Remove prototype.
1048 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1049 * insdel.c (move_gap): Likewise.
1051 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
1053 * xdisp.c (redisplay_internal): Remove now-unused local.
1055 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1057 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1058 (redisplay_internal): Don't bother selecting the frame to get the
1059 proper value of frame-local variables (bug#13225).
1061 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1063 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1064 Rename 4th argument since it may be buffer or string. Adjust comment.
1065 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1067 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1069 * coding.c (Fdetect_coding_region): Do not check start and end with
1070 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1071 (code_convert_region): Likewise.
1073 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1075 * w32.c (acl_get_file, acl_set_file): Run the file name through
1076 map_w32_filename, and resolve any symlinks in the file name, like
1078 (acl_set_file): Call revert_to_self, if any privileges were
1081 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1083 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1084 ($(BLD)/w32.$(O)): Update dependencies.
1086 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1088 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1089 propagate redisplay's scrolling (if any) to the right window.
1090 (redisplay_internal): Use ensure_selected_frame.
1091 (display_mode_lines): Complete last fix.
1092 * window.c (select_window_1): New func, extracted from select_window.
1093 (select_window): Use it.
1094 * window.h (select_window_1): Declare.
1096 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1098 Emulate Posix ACL APIs on MS-Windows.
1099 * w32.c: Include sddl.h and sys/acl.h.
1100 (SDDL_REVISION_1): Define if not already defined.
1101 (g_b_init_get_security_descriptor_dacl)
1102 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
1103 (g_b_init_is_valid_security_descriptor)

1116 (acl_free, acl_get_file, acl_set_file): New functions.
1118 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1120 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1122 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1123 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1124 for some of that bug's symptoms can now cause Emacs to abort.
1125 Remove the workaround.
1126 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1127 The bug that caused SIGCHLD to get lost has been fixed, and the
1128 workaround for it can now cause Emacs to abort.
1130 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1132 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1133 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1134 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1136 2012-12-16 Romain Francoise <romain@orebokech.com>
1138 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1139 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1140 and copy ACL entries of file in addition to SELinux context if set.
1141 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1143 * Makefile.in (LIBACL_LIBS): New macro.

1148 * fileio.c (internal_delete_file): Use bool for boolean.
1150 2012-12-15 Eli Zaretskii <eliz@gnu.org>
1152 Fix bug #13079 on MS-Windows with temp files not being deleted.

1155 (register_child): First argument is now pid_t.
1156 (record_infile, record_pending_deletion): New prototypes.
1158 * w32proc.c (new_child): Initialize input_file and
1159 pending_deletion members of the child.
1160 (delete_child): Delete the child's temporary input file, if any,
1161 that is pending deletion.
1162 (register_child): First argument is now pid_t.
1163 (record_infile, record_pending_deletion): New functions.
1164 (reap_subprocess): Fix a typo in DebPrint string.
1165 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1167 * fileio.c (internal_delete_file): Return an int again: non-zero
1168 if delete-file succeeds, zero otherwise.
1170 * lisp.h (internal_delete_file): Adjust prototype.
1172 * callproc.c (Fcall_process): Don't overwrite infile with result
1174 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1175 asynchronous subprocess, record the name of the input file name,
1177 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1178 delete the file, record it as pending deletion when the subprocess
1181 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1183 * editfns.c [HAVE_PWD_H]: Include grp.h.
1185 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1187 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1189 Fix permissions bugs with setgid directories etc. (Bug#13125)
1190 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1191 to mark it as a placeholder. The old value was often wrong.
1192 The only user of this attribute has been changed to use
1193 file-ownership-preserved-p instead, with its new group arg.
1194 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1196 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

1201 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1203 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1204 try to get accurate owner and group information from NT file
1205 security APIs. This is to make most callers of 'stat' and
1206 'lstat', which don't need that information, much faster.
1208 * dired.c (Ffile_attributes) [WINDOWSNT]:
1209 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1210 owner and group information from 'lstat'.
1212 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1214 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1215 as that confuses set-auto-coding, so insist on the head-read
1216 returning the full 1024 bytes. Let lseek compute the tail offset;
1217 less work for us. Do not ignore I/O errors when reading the tail.
1219 * xdisp.c: Minor style fixes.
1220 (init_iterator): Hoist assignment out of if-expression.
1221 (markpos_of_region): Callers now test for sign, not for -1.
1223 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>

1226 * xdisp.c (markpos_of_region): New function.
1227 (init_iterator): Do not highlight the region of zero length.
1228 (redisplay_window): Check whether the region is of non-zero length.
1229 (try_cursor_movement): Allow if the region length is zero.

1234 * search.c (search_buffer): Check the inverse translations of each
1235 character in pattern when the buffer being searched is unibyte.
1238 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1240 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1241 files, fixing a regression from 24.2.
1242 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1244 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1246 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1247 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1248 Remove unnecessary S_ISLNK test, as (contra the comments) this
1249 function can't copy symlinks. Improve quality of error message
1250 when attempting to copy files that are neither regular files nor

1258 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1259 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1261 2012-12-12 Daniel Colascione <dancol@dancol.org>
1263 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1264 the dumped Emacs is not a sparse file, greatly improving Cygwin
1265 "make bootstrap" performance.
1267 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1269 * inotify.c (inotify_callback): Generate an Emacs event for every
1270 incoming inotify event.
1272 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1274 * xdisp.c (handle_face_prop): Fix logic of computing
1275 it->start_of_box_run_p.
1276 (append_space_for_newline): If the glyph row is R2L, reset the
1277 iterator's end_of_box_run_p flag before prepending the space glyph.
1278 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1279 iterator's start_of_box_run_p flag before prepending the stretch.
1280 (append_glyph, produce_image_glyph, append_composite_glyph)
1281 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1282 left_box_line_p and right_box_line_p flags of the glyph for R2L
1283 glyph rows. (Bug#13011)
1285 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1287 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
1288 if changed buffer is not shown in a window.
1289 * insdel.c (prepare_to_modify_buffer): Likewise.
1290 * window.c (replace_buffer_in_windows_safely): Do nothing
1291 if buffer is not shown in a window.

1297 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1298 encoded_file_name, which is what it is.
1300 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1302 Consistently use marker_position and marker_byte_position.
1303 * fringe.c (Ffringe_bitmaps_at_pos):

1311 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
1312 Replace direct access to marker fields with calls
1313 to marker_position and/or marker_byte_position.

1326 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1329 * w32fns.c (cache_system_info): Initialize the global hinst
1330 variable here so various initialization calls DTRT.
1332 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1333 (hinst): Remove unneeded extern declaration.
1334 (_start): Remove initialization of above variables; remove
1335 initialization of hinst, as cache_system_info now does that.

1444 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
1446 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
1448 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
1449 DWORD_PTR, for compatibility with 64-bit builds.
1451 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
1452 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
1453 (system_process_attributes): Use SIZE_T rather than DWORD, for
1454 compatibility with 64-bit builds.

1460 2012-12-10 Eli Zaretskii <eliz@gnu.org>
1462 * indent.c (Fvertical_motion): If a display string will be
1463 displayed on the left or the right margin, don't consider it as a
1464 factor in cursor positioning. (Bug#13108)
1466 2012-12-10 Martin Rudalics <rudalics@gmx.at>
1468 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.

1475 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1477 * w32.c (unsetenv): Return 0 if the input string is too long.
1479 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1481 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1482 * alloc.c (xputenv): New function.
1483 * dbusbind.c (Fdbus_init_bus):
1485 * xterm.c (x_term_init):
1486 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1487 * editfns.c (initial_tz): Move static var decl up.
1488 (tzvalbuf_in_environ): New static var.
1489 (init_editfns): Initialize these two static vars.
1490 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1491 Save old TZ value on stack, if it's small.
1492 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1493 instead, use xputenv+unsetenv to set and restore TZ.
1494 (environbuf): Remove static var. All uses removed.
1495 (Fset_time_zone_rule): Do not save TZ and environ;
1496 no longer needed here.
1497 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1498 Move to inside set_time_zone_rule; they don't need file scope any more.
1499 (set_time_zone_rule): Maintain the TZ=value string separately.
1500 (syms_of_editfns): Don't initialize initial_tz;
1501 init_editfns now does it.
1502 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1503 * lisp.h (xputenv): New decl.
1505 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1507 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1509 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1511 * w32.c (unsetenv, sys_putenv): New functions.
1513 2012-12-08 Chong Yidong <cyd@gnu.org>
1515 * editfns.c (Finsert_char): Make the error message more
1516 informative (Bug#12992).
1518 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1520 Simplify get_lim_data.
1521 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1522 Remove USG and vlimit methods; no longer used these days.
1523 Add #error catchall just in case.
1525 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1526 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1527 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1528 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1529 (deleted_pid_list, Fdelete_process, create_process)
1530 (record_child_status_change, handle_child_signal, deliver_child_signal)
1531 (init_process_emacs, syms_of_process):
1532 Assume SIGCHLD is defined.
1533 (parse_signal): Remove. All uses removed.
1534 (abbr_to_signal): New static function.
1535 (Fsignal_process): Use it to convert signal names to ints.
1536 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1537 kill (getpgrp (), ...).
1538 (emacs_sigaction_init): Assume SIGCHLD is defined.
1539 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1540 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.

1542 All uses replaced by 'kill' with a negative pid.
1543 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1544 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1546 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1548 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1549 This will cause a production Emacs to dump core instead of
1552 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1554 * frame.c (make_frame): Do not set window's buffer to t.
1555 * window.c (Fsplit_window_internal): Likewise. Previously it was
1556 used to indicate that the window is being set up. Now we use
1557 set_window_buffer for all new windows, so the condition in ...
1558 (Fset_window_buffer): ... is always true and can be removed.
1560 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1562 Convenient macro to check whether the buffer is hidden.
1563 * buffer.h (BUFFER_HIDDEN_P): New macro.
1564 * frame.c (make_frame): Use it. Adjust comment.
1565 * buffer.c (candidate_buffer): New function.
1566 (Fother_buffer, other_buffer_safely): Use it.
1568 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1570 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1571 if the child process is still running. Instead, exit the wait
1572 loop and return zero. (Bug#13086)
1574 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1576 * frame.h (x_char_width, x_char_height): Remove prototypes.

1589 Fix a recently-introduced delete-process race condition.
1590 * callproc.c, process.h (record_kill_process):
1591 New function, containing part of the old call_process_kill.
1592 (call_process_kill): Use it.
1593 This does not change call_process_kill's behavior.
1594 * process.c (Fdelete_process): Use record_kill_process to fix a
1595 race condition that could cause Emacs to lose track of a child.
1597 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1599 Avoid code duplication between prev_frame and next_frame.
1600 * frame.c (candidate_frame): New function. Add comment.
1601 (prev_frame, next_frame): Use it. Adjust comment.
1603 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1605 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1606 fails, signal an error instead of continuing with an empty
1608 Encode expanded temp file pattern before passing it to mkstemp or
1611 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1612 Encode the file name before passing it to dostounix_filename, in
1613 case it will downcase it (under w32-downcase-file-names).
1616 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1618 Minor call-process cleanups.
1619 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1620 at the same time as other platforms, to simplify analysis.
1621 No need for fd0_volatile since we have synch_process_fd.
1622 Avoid needless emacs_close; arg is always negative.
1624 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1626 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1629 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1631 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1632 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1633 and mouse_face_hidden members to a bitfields.
1634 * frame.h (struct frame): Remove set-but-not-used space_width member.
1635 (FRAME_SPACE_WIDTH): Remove.
1636 * nsterm.m, w32term.c, xterm.c: Adjust users.
1637 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1638 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1639 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1640 members to a bitfields.
1642 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1644 Don't let call-process be a zombie factory (Bug#12980).
1645 Fixing this bug required some cleanup of the signal-handling code.
1646 As a side effect, this change also fixes a longstanding rare race
1647 condition whereby Emacs could mistakenly kill unrelated processes,
1648 and it fixes a bug where a second C-g does not kill a recalcitrant
1649 synchronous process in GNU/Linux and similar platforms.
1650 The patch should also fix the last vestiges of Bug#9488,
1651 a bug which has mostly been fixed on the trunk by other changes.
1652 * callproc.c, process.h (synch_process_alive, synch_process_death)
1653 (synch_process_termsig, sync_process_retcode):
1654 Remove. All uses removed, to simplify analysis and so that
1655 less consing is done inside critical sections.
1656 * callproc.c (call_process_exited): Remove. All uses replaced
1657 with !synch_process_pid.
1658 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1659 These take the role of what used to be in unwind-protect arg.
1661 (block_child_signal, unblock_child_signal):
1662 New functions, to avoid races that could kill innocent-victim processes.
1663 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1664 (call_process_kill): Record killed processes as deleted, so that
1665 zombies do not clutter up the system. Do this inside a critical
1666 section, to avoid a race that would allow the clutter.
1667 (call_process_cleanup): Fix code so that the second C-g works again
1668 on common platforms such as GNU/Linux.
1669 (Fcall_process): Create the child process in a critical section,
1670 to fix a race condition. If creating an asynchronous process,
1671 record it as deleted so that zombies do not clutter up the system.
1672 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1673 light of these changes. Omit unnecessary call to emacs_close
1674 before failure, as the unwind-protect code does that.
1675 * callproc.c (call_process_cleanup):
1676 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1677 * process.c (record_deleted_pid): New function, containing
1678 code refactored out of Fdelete_process.
1679 (Fdelete_process): Use it.
1680 (process_status_retrieved): Remove. All callers changed to use
1681 child_status_change.
1682 (record_child_status_change): Remove, folding its contents into ...
1683 (handle_child_signal): ... this signal handler. Now, this
1684 function is purely a handler for SIGCHLD, and is not called after
1685 a synchronous waitpid returns; the synchronous code is moved to
1686 wait_for_termination. There is no need to worry about reaping
1687 more than one child now.
1688 * sysdep.c (get_child_status, child_status_changed): New functions.
1689 (wait_for_termination): Now takes int * status and bool
1690 interruptible arguments, too. Do not record child status change;
1691 that's now the caller's responsibility. All callers changed.
1692 Reimplement in terms of get_child_status.
1693 (wait_for_termination_1, interruptible_wait_for_termination):
1694 Remove. All callers changed to use wait_for_termination.
1695 * syswait.h: Include <stdbool.h>, for bool.
1696 (record_child_status_change, interruptible_wait_for_termination):
1698 (record_deleted_pid, child_status_changed): New decls.
1699 (wait_for_termination): Adjust to API changes noted above.
1701 * bytecode.c, lisp.h (Qbytecode): Remove.
1702 No longer needed after 2012-11-20 interactive-p changes.
1704 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1706 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1707 the scroll margin, move point outside the margin. (Bug#13055)
1709 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1711 * gtkutil.c (my_log_handler): New function.
1712 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1714 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1716 * lisp.h (modify_region): Rename to...
1717 (modify_region_1): ...new prototype.
1718 * textprop.c (modify_region): Now static. Adjust users.
1719 * insdel.c (modify_region): Rename to...
1720 (modify_region_1): ...new function to work with current buffer.
1721 Adjust comment and users. Use true and false for booleans.
1723 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1725 * alloc.c (free_save_value): New function.
1726 (safe_alloca_unwind): Use it.
1727 * lisp.h (free_save_value): New prototype.
1728 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1730 (save_excursion_restore): Adjust to match saved data structure.
1731 Use free_save_value to offload some work from GC. Drop obsolete
1734 2012-12-03 Chong Yidong <cyd@gnu.org>
1736 * fileio.c (Vauto_save_list_file_name): Doc fix.
1738 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1740 * w32fns.c: Remove prototype of atof.
1741 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1743 (file_dialog_callback): Make it UINT_PTR.
1745 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1748 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1749 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1752 2012-12-03 Glenn Morris <rgm@gnu.org>
1754 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1756 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1758 Fix xpalloc confusion after memory is exhausted.
1759 * alloc.c (xpalloc): Comment fix.
1760 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1761 and signals an error, do not clear charset_table_size, as
1762 charset_table is still valid.
1763 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1765 Use execve to avoid need to munge environ (Bug#13054).
1766 * callproc.c (Fcall_process):
1767 * process.c (create_process):
1768 Don't save and restore environ; no longer needed.
1769 * callproc.c (child_setup):
1770 Use execve, not execvp, to preserve environ.
1772 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1774 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1776 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1778 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1779 display for sliced images (Bug#10500).
1781 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1783 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1785 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1786 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1788 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1790 * xdisp.c (window_outdated): Remove eassert since it hits
1791 some suspicious corner cases (see Bug#13007 and Bug#13012).
1792 (mode_line_update_needed): New function.
1793 (redisplay_internal, redisplay_window): Use it.
1794 (ensure_selected_frame): New function.
1795 (redisplay_internal, unwind_redisplay): Use it.
1796 (redisplay_internal): Move comment about buffer_shared...
1797 (buffer_shared_and_changed): ...near to its real use.
1799 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1801 * callproc.c (Fcall_process): Don't misreport vfork failure.
1803 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1805 * callproc.c (Fcall_process): Fix vfork portability problems.
1806 Do not assume that fd[0], count, filefd, and save_environ survive
1807 vfork. Fix bug whereby wrong errno value could be reported for
1808 pipe failure. Some minor cleanups, too, as follows. Move buf and
1809 bufsize to the context where they're needed. Change new_argv to
1810 be of type char **, as this is more convenient and avoids casts.
1811 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1812 Now local constants, not macros.
1814 2012-11-18 Kenichi Handa <handa@gnu.org>
1816 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1817 for the variable "f".
1819 2012-11-13 Kenichi Handa <handa@gnu.org>
1821 * font.c (font_unparse_xlfd): Exclude special characters from the
1822 generating XLFD name.
1824 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1826 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1834 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1835 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1836 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1837 * lread.c (readbyte_from_file): Assume EINTR is defined.
1838 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1839 Assume EIO and EAGAIN are defined.
1840 * unexcoff.c (write_segment): Assume EFAULT is defined.
1842 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1844 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1847 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1848 highlighting on the frame was cleared. Prevents assertion
1849 violations when repeatedly clicking on the "Top" link of the
1850 "bread-crumbs" in Info buffers.
1852 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1854 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1856 2012-11-24 Ken Brown <kbrown@cornell.edu>

1859 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1860 were always defined.
1862 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1864 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1865 between bpos_covered and bpos_max. This fixes cursor display when
1866 several display strings follow each other.
1868 * .gdbinit (pgx): If the glyph's object is a string, display the
1869 pointer to string data, rather than the value of the string object
1870 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1872 * indent.c (Fvertical_motion): If the starting position is covered
1873 by a display string, return to one position before that, to avoid
1874 overshooting it inside move_it_to. (Bug#12930)
1876 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1878 * frame.h (struct frame): Remove display_preempted member

1881 * w32menu.c (pending_menu_activation): Remove since not
1883 (set_frame_menubar): Adjust user.
1884 * w32term.h (struct x_output): Drop outdated #if 0 code.
1885 (struct w32_output): Use bitfields for explicit_parent,
1886 asked_for_visible and menubar_active members.
1887 Drop unused pending_menu_activation member.
1888 * xterm.h (struct x_output): Drop outdated #if 0 code.
1889 Use bitfields for explicit_parent, asked_for_visible,
1890 has_been_visible and net_wm_state_hidden_seen members.
1892 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1894 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1895 of a literal "/". (Bug#12955)
1896 (gl-stamp): Invoke fc.exe directly, not through cmd.
1898 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1900 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1901 * dired.c: Assume HAVE_DIRENT_H.
1902 (NAMLEN): Remove, replacing with ...
1903 (dirent_namelen): New function. All uses changed. Use the GNU macro
1904 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1905 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1906 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1907 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1909 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1910 * ndir.h: Rename to ../nt/inc/dirent.h.
1911 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1912 Do not include <dirent.h>; no longer needed.
1913 * w32.c: Include <dirent.h> rather than "ndir.h".
1915 2012-11-23 Chong Yidong <cyd@gnu.org>
1917 * xftfont.c (xftfont_open): Remove duplicate assignment.
1919 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1921 * alloc.c (Fgarbage_collect): Unblock input after clearing
1922 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1923 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1924 * msdos.c (IT_frame_up_to_date): Use it here...
1925 * w32term.c (w32_frame_up_to_date): ...here...
1926 * xterm.c (XTframe_up_to_date): ...and here...
1927 * nsterm.m (ns_frame_up_to_date): ...but not here.
1928 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1930 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1931 Do not check whether GC is in progress.
1933 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1935 * xdisp.c (window_buffer_changed): New function.
1936 (update_menu_bar, update_tool_bar): Use it to
1937 simplify large 'if' statements.

1939 'tail' and 'frame' local variables.
1941 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1943 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1944 with Windows system header.
1946 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1948 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1949 * alloc.c: Assume unistd.h exists.
1950 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1951 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1952 (getwd) [USG]: Remove; no longer needed.
1953 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1954 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1955 * w32.h (getcwd): Remove decl.
1957 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1959 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1960 Make it set selected_window as well.
1961 (update_tool_bar): Use it.
1963 2012-11-21 Ken Brown <kbrown@cornell.edu>
1965 * emacs.c (main): Set the G_SLICE environment variable for all
1966 Cygwin builds, not just GTK builds. See
1967 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1969 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1971 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1972 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1973 Define for the MSVC compiler.
1975 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1977 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1978 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1979 dostounix_filename. Prevents crashes down the road, because
1980 dostounix_filename assumes it gets a unibyte string.
1981 Reported by Michel de Ruiter <michel@sentient.nl>, see
1982 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1984 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1990 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1991 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1992 Test NILP rather than Qunbound.
1993 (Ffmakunbound): Set to Qnil.
1994 (Fsymbol_function): Never signal an error.
1995 (Finteractive_form): Ignore Qunbound.
1997 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1999 * eval.c (interactive_p): Remove no-longer-used decl.
2001 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2003 * xdisp.c (buffer_shared): Adjust comment.
2004 (buffer_shared_and_changed): New function.
2005 (prepare_menu_bars, redisplay_internal): Use it to
2006 decide whether all windows or frames should be updated.
2007 (window_outdated): New function.
2008 (text_outside_line_unchanged_p, redisplay_window): Use it.
2009 (redisplay_internal): Likewise. Fix indentation.
2011 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2013 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2014 (syms_of_eval): Remove corresponding defsubr.
2015 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2017 2012-11-19 Daniel Colascione <dancol@dancol.org>
2019 * w32fns.c (Fx_file_dialog):
2020 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2021 cygwin_convert_file_name*.
2023 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2024 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2026 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2028 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2030 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2032 * w32select.c: Include w32common.h before w32term.h, so that
2033 windows.h gets included before w32term.h uses some of its
2034 features, see below.
2036 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2038 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2040 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2042 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2044 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2045 (ns_select): Return at once if events are held (Bug#12834).
2047 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2049 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2050 Needed following 2012-10-20 change. (Bug#12902)
2052 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2054 * w32proc.c (waitpid): Remove unused label get_result.
2056 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2058 * makefile.w32-in (SYSWAIT_H): New macro.
2059 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2060 ($(BLD)/sysdep.$(O)): Update dependencies.
2062 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2064 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2065 * callproc.c (relocate_fd): Assume F_DUPFD.
2066 * emacs.c, term.c (O_RDWR): Remove.
2067 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2068 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2069 * nsterm.m: Assume <fcntl.h> exists.
2070 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2071 (create_pty, Fmake_network_process, server_accept_connection)
2072 (wait_reading_process_output, init_process_emacs):
2074 (wait_reading_process_output): Put in a special case for WINDOWSNT
2075 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2076 It's not clear this is needed, but it's a more-conservative change.
2077 (create_process): Assume FD_CLOEXEC.
2078 (create_process, create_pty): Assume O_NOCTTY.
2079 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2080 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2081 Omit if not DOS_NT, since F_GETFL is not defined there.
2082 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2083 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2085 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2086 lack it, since gnulib guarantees this.
2087 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2089 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2091 * w32.c (faccessat): Pretend that directories have the execute bit
2092 set. Emacs expects that, e.g., in files.el:cd-absolute.
2094 * w32proc.c (create_child): Don't clip the PID of the child
2095 process to fit into an Emacs integer, as this is no longer a
2097 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2098 reaping only the process specified by PID argument, if that is
2099 positive. Use PID instead of dead_child to know which process to
2100 reap. Wait for the child to die only if WNOHANG is not in
2102 (sys_select): Don't set dead_child.
2104 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2105 as it is no longer needed.
2107 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2109 (record_child_status_change): Remove the setting of
2110 record_at_most_one_child for the !WNOHANG case.
2112 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2114 Fix problems in ns port found by static checking.
2115 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2116 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2117 not to process group.
2118 (ns_select): Use emacs_write, not write, as that's more robust
2119 in the presence of signals.
2120 (fd_handler:): Check for read errors.
2122 2012-11-16 Glenn Morris <rgm@gnu.org>
2124 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2126 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2128 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2130 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2132 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2133 use the same value of thread handle.
2134 (start_timer_thread): If the timer thread exited (due to error),
2135 clean up by closing the two handles it used. Duplicate the caller
2136 thread's handle here, so it gets duplicated only once, when
2137 launching the timer thread. Set priority of the timer thread, not
2139 (getitimer): Don't duplicate the caller thread's handle here.
2142 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2144 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2147 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2149 Remove no-longer-used pty_max_bytes variable.
2150 * process.c (pty_max_bytes): Remove; unused.
2151 (send_process): Do not set it.
2153 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2155 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2156 Update dependencies.
2158 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2160 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2161 This follows up on the 2012-09-29 patch that removed indirection
2162 for the 'function' field. Reported by Sergey Vinokurov in
2163 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2165 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2167 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2168 different name, as the MS runtime does not have such a function,
2169 and probably never will.) All callers changed. Ignore DIRFD
2170 value if PATH is an absolute file name, to match Posix spec
2171 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2174 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2176 * xdisp.c (echo_area_display, redisplay_internal):
2177 Omit redundant check whether frame_garbaged is set.
2179 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2181 Use faccessat, not access, when checking file permissions (Bug#12632).
2182 This fixes a bug that has been present in Emacs since its creation.
2183 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2184 which must set some sort of record. (Torek's bug report was against
2185 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2186 same common flaw.) See Torek's Usenet posting
2187 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2188 Posted: Fri Apr 8 14:18:56 1983.
2189 * Makefile.in (LIB_EACCESS): New macro.
2191 * callproc.c (init_callproc):
2192 * charset.c (init_charset):
2193 * fileio.c (check_existing, check_executable, check_writable)
2195 * lread.c (openp, load_path_check):
2196 * process.c (allocate_pty):
2198 Use effective UID when checking permissions, not real UID.
2199 * callproc.c (init_callproc):
2200 * charset.c (init_charset):
2201 * lread.c (load_path_check, init_lread):
2202 Test whether directories are accessible, not merely whether they exist.
2203 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2204 * fileio.c (check_existing, check_executable, check_writable)
2206 Use symbolic names instead of integers for the flags, as they're
2208 (check_writable): New arg AMODE. All uses changed.
2209 Set errno on failure.
2210 (Ffile_readable_p): Use faccessat, not stat + open + close.
2211 (Ffile_writable_p): No need to call check_existing + check_writable.
2212 Just call check_writable and then look at errno. This saves a syscall.
2213 dir should never be nil; replace an unnecessary runtime check
2214 with an eassert. When checking the parent directory of a nonexistent
2215 file, check that the directory is searchable as well as writable, as
2216 we can't create files in unsearchable directories.
2217 (file_directory_p): New function, which uses 'stat' on most platforms
2218 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2219 (Ffile_directory_p, Fset_file_times): Use it.
2220 (file_accessible_directory_p): New function, which uses a single
2221 syscall for efficiency.
2222 (Ffile_accessible_directory_p): Use it.
2223 * xrdb.c (file_p): Use file_directory_p.
2224 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2225 * lread.c (openp): When opening a file, use fstat rather than
2226 stat, as that avoids a permissions race. When not opening a file,
2227 use file_directory_p rather than stat.
2228 (dir_warning): First arg is now a usage string, not a format.
2229 Use errno. All uses changed.
2230 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2231 that merely introduced a race.
2232 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2233 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2234 and similarly for the other O_* flags.
2235 * w32.c (sys_faccessat): Rename from sys_access and switch to
2236 faccessat's API. All uses changed.
2237 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2238 (magic_db): Rename from magic_file_p.
2239 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2240 char *, so that we don't have to test for file existence
2241 separately from opening the file for reading. This removes a race
2242 fixes a permission-checking problem, and simplifies the code.
2244 (file_p): Remove; no longer needed.
2246 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2248 Omit glyphs initialization at startup.
2249 * dispnew.c (glyphs_initialized_initially_p): Remove.
2250 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2251 (Fredraw_frame): Move actual code from here...
2252 (redraw_frame): ...to here. Add eassert. Adjust comment.
2253 (Fredraw_display): Use redraw_frame.
2254 * xdisp.c (clear_garbaged_frames): Likewise.
2256 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2258 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2259 passed to pint2str and pint2hrstr to be at most the size of the
2260 frame's decode_mode_spec_buffer. This avoids crashes with very
2261 large values of FIELD_WIDTH argument to decode_mode_spec.
2264 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2266 Fix a race with verify-visited-file-modtime (Bug#12863).
2267 Since at least 1991 Emacs has ignored an mtime difference of no
2268 more than one second, but my guess is that this was to work around
2269 file system bugs that were fixed long ago. Since the race is
2270 causing problems now, let's remove that code.
2271 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2272 whose time stamp is off by no more than a second. Insist that the
2273 file time stamps match exactly.
2275 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2277 * frame.h (struct frame): Convert external_tool_bar member to
2278 1-bit unsigned bitfield.
2279 * termhooks.h (struct terminal): Remove mouse_moved member since
2280 all users are long dead. Adjust comment on mouse_position_hook.
2282 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2284 Simplify by using FOR_EACH_FRAME here and there.
2285 * frame.c (next_frame, prev_frame, other_visible_frames)
2286 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2287 * w32term.c (x_window_to_scroll_bar): Likewise.
2288 * window.c (window_list): Likewise.
2289 * xdisp.c (x_consider_frame_title): Likewise.
2290 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2291 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2292 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2293 * xmenu.c (menubar_id_to_frame): Likewise.
2294 * xselect.c (frame_for_x_selection): Likewise.
2295 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2296 (x_window_to_menu_bar): Likewise.
2297 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2299 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2301 * data.c (Qdefalias_fset_function): Now static.
2303 Another tweak to vectorlike_header change.
2304 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2305 Remove, and replace all uses with ...
2306 (next_in_free_list, set_next_in_free_list):
2307 New functions, which respect C's aliasing rules better.
2309 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2311 * window.c (list4i): Rename from 'quad'. All uses changed.
2312 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2314 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2316 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2317 warning about mixing declarations and code in ISO C90.
2319 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2321 * window.c (Fsplit_window_internal): Set combination limit of
2322 new parent window to t iff Vwindow_combination_limit is t;
2323 fixing a regression introduced with the change from 2012-09-22.
2324 (Fset_window_combination_limit): Fix doc-string.
2326 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2328 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2329 amount when the scroll margins are too large. When scrolling
2330 backwards in the buffer, give up if cannot reach point or the
2331 scroll margin within a reasonable number of screen lines.
2332 Fixes point position in window under scroll-up/down-aggressively when
2333 point is positioned many lines beyond the window top/bottom.
2336 * ralloc.c (relinquish): If real_morecore fails to return memory
2337 to the system, don't crash; instead, leave the last heap
2338 unchanged and return. (Bug#12774)
2340 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2342 * lisp.h (AUTOLOADP): New macro.
2343 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2344 * data.c (Ffset): Remove special ad-advice-info handling.

2368 Tweak last vectorlike_header change.
2369 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2370 vectorlike object on the free list. This is introduced to avoid
2371 some (but not all) pointer casting and aliasing problems, see
2372 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2373 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

2377 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2379 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

2405 special hash function containing a comparison that always yields 1.
2407 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2409 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2410 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2411 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2414 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2416 * image.c (xpm_make_color_table_h): Fix compiler error because
2417 make_hash_table changed.
2419 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2421 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2423 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2425 Use ad-hoc comparison function for the profiler's hash-tables.
2426 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2427 (make_log): Use them.
2428 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2429 call Fequal any more.

2438 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2439 (hash_lookup, hash_remove_from_table): Move assertion checking of
2440 hashfn result here. Check hash-equality before calling cmpfn.

2453 value of w32-scroll-lock-modifier is neither nil nor one of the
2454 known key modifiers. (Bug#12806)
2456 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2458 Shrink struct vectorlike_header to the only size field.
2459 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2461 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2462 PVEC_TYPE_MASK to arrange new bitfield in the vector header.

2482 (allocate_vector_from_block): Simplify.
2483 (PSEUDOVECTOR_NBYTES): Replace with...

2486 (allocate_vectorlike): Likewise.
2487 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2488 Add easserts. Adjust XSETPVECTYPESIZE usage.
2489 (allocate_buffer): Use BUFFER_PVEC_INIT.
2490 (live_vector_p): Adjust to match large vector.
2491 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2492 * buffer.h (struct buffer): Add next member.
2493 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2495 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

2501 (xvecsize): New command.
2503 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2505 * keyboard.c (event_to_kboard): Do not dereference
2506 frame_or_window field of SELECTION_REQUEST_EVENT
2507 and SELECTION_CLEAR_EVENT events (Bug#12814).
2508 * xterm.h (struct selection_input_event): Adjust comment.
2510 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2512 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2513 such as Scroll Lock, if the respective keys are treated as
2514 function keys, not as modifiers. This avoids destroying non-ASCII
2515 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2517 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2519 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2521 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2523 Restore some duplicate definitions (Bug#12814).
2524 This undoes part of the 2012-11-03 changes. Some people build
2525 with plain -g rather than with -g3, and they need the duplicate
2526 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2527 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2528 Define as macros, as well as as enums or as constants.
2530 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2532 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2533 to keypad keys (Bug#12816).
2535 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2537 Minor adjustments of recently-changed frame functions.
2538 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2539 known to be a frame (we're in the FRAMEP branch).
2540 * lisp.h (Qframep): Remove decl. frame.h declares this.
2541 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2542 since they're meant for Lisp fixnum values.
2544 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2546 * window.c (Fwindow_combination_limit): Revert to the only
2547 required argument and adjust docstring as suggested in
2548 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2549 by Martin Rudalics <rudalics@gmx.at>.
2551 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2553 Widely used frame validity and checking functions.
2554 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2555 * frame.c (decode_live_frame, decode_any_frame): New functions.
2556 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2557 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2558 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

2566 * lisp.h (frame_buffer_predicate): Remove prototype.
2567 * buffer.c (Fother_buffer): Use decode_any_frame.
2568 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2569 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2570 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2571 (Fclose_font, Ffont_info): Use decode_live_frame.
2572 * fontset.c (check_fontset_name): Likewise.
2573 * terminal.c (Fframe_terminal): Likewise.
2574 * w32fns.c (check_x_frame): Likewise.
2575 * window.c (Fminibuffer_window, Fwindow_at)
2576 (Fcurrent_window_configuration): Likewise.
2577 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2578 Likewise. Allow zero number of arguments. Adjust docstring.
2579 * dispnew.c (Fredraw_frame): Likewise.
2580 * xfaces.c (frame_or_selected_frame): Remove.
2581 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2582 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2583 (Fframe_face_alist): Use decode_live_frame.
2584 * xfns.c (check_x_frame): Likewise.
2586 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2588 * window.c (quad): New function.
2589 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2590 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2591 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2592 (Fwindow_line_height): Use it.
2593 (Fwindow_fringes): Use list3.
2594 (Fwindow_scroll_bars): Use list4.
2595 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2596 (Fwindow_combination_limit): Allow zero number of arguments.
2598 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2600 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2602 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2603 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2604 file descriptor 2 for standard error. (Bug#12805)
2606 2012-11-05 Chong Yidong <cyd@gnu.org>
2608 * process.c (wait_reading_process_output): Revert previous change.
2610 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2612 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2613 This removes code that has been obsolete since around 1990.
2614 * callproc.c (Fcall_process):
2616 * process.c (create_process):
2617 * term.c (dissociate_if_controlling_tty):
2618 Assume setsid exists.
2619 * callproc.c (child_setup): Assume setpgid exists and behaves as
2620 per POSIX.1-1988 or later.
2621 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2622 * emacs.c (shut_down_emacs):
2623 * sysdep.c (sys_suspend, init_foreground_group):
2624 Assume getpgrp behaves as per POSIX.1-1998 or later.
2625 * msdos.c (setpgrp): Remove.
2626 (tcgetpgrp, setpgid, setsid): New functions.
2627 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2628 * term.c (no_controlling_tty): Remove; unused.
2629 * w32proc.c (setpgrp): Remove.
2630 (setsid, tcgetpgrp): New functions.
2632 Simplify by assuming __fpending.
2633 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2634 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2635 Do not assume that __fpending's result fits in int.
2637 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2639 Remove EMACS_OUTQSIZE+sleep hack.
2640 * dispnew.c (update_frame_1): Remove hack for terminals slower
2641 than 2400 bps, which throttled Emacs by having it sleep.
2642 This code hasn't worked since at least 2007, when the multi-tty stuff
2643 was added, and anyway those old terminals are long dead.
2644 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2645 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2647 Fix data-loss with --version (Bug#9574).
2648 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2649 as we can't assume that emacs_strerror is initialized, and strerror
2650 is good enough here.
2651 (main): Invoke atexit earlier, to catch earlier instances of
2652 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2654 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2656 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2657 (keyDown): Remap keypad keys to X11 virtual key codes.
2659 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2661 Fix data-loss with --batch (Bug#9574).
2662 * emacs.c: Include <close-stream.h>.
2663 (close_output_streams): New function.
2664 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2665 and handles errors appropriately.
2666 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2669 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2670 The symptom is a diagnostic "GLib-WARNING **: In call to
2671 g_spawn_sync(), exit status of a child process was requested but
2672 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2673 waitpid(), so exit status can't be returned." The diagnostic
2674 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2675 The real bug is a race condition between Emacs and glib: Emacs
2676 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2677 so that glib can't find it. Work around the bug by invoking
2678 waitpid only on subprocesses that Emacs itself creates.
2679 * process.c (create_process, record_child_status_change):
2680 Don't use special value -1 in pid field, as the caller now must
2681 know the pid rather than having the callee infer it.
2682 The inference was sometimes incorrect anyway, due to another race.
2683 (create_process): Set new 'alive' member if child is created.
2684 (process_status_retrieved): New function.
2685 (record_child_status_change): Use it.
2686 Accept negative 1st argument, which means to wait for the
2687 processes that Emacs already knows about. Move special-case code
2688 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2689 processes that have already been waited for, by testing and
2690 clearing new 'alive' member.
2691 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2692 now does this internally.
2693 (handle_child_signal): Let record_child_status_change do all
2694 the work, since we do not want to reap all exited child processes,
2695 only the child processes that Emacs itself created.
2696 * process.h (Lisp_Process): New boolean member 'alive'.
2698 Omit duplicate definitions no longer needed with gcc -g3.
2699 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2700 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2701 Define only as macros. There's no longer any need to also define
2702 these symbols as enums or as constants, since we now assume
2703 gcc -g3 when debugging.
2705 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2707 * lisp.mk: Adjust comments to the fact that term/internal is now
2708 loaded from loadup.el.
2710 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2711 (msdos_fatal_signal): New function.
2712 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2715 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2716 for GCC versions before 4.
2717 (emacs_raise): Define to call msdos_fatal_signal.
2719 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2720 iterator when starting in the middle of a display or overlay
2723 2012-11-03 Chong Yidong <cyd@gnu.org>
2725 * process.c (wait_reading_process_output): Clean up the last
2728 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2730 * process.c (wait_reading_process_output): Avoid a race condition
2731 with SIGIO delivery (Bug#11536).
2733 2012-11-03 Chong Yidong <cyd@gnu.org>
2735 * buffer.c (cursor_type): Untabify docstring.
2737 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2739 * frame.h (struct frame): Drop can_have_scroll_bars member
2740 which is meaningless for a long time. Adjust comments.
2741 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2742 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2744 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2746 * window.c (decode_next_window_args): Update window arg after
2747 calling decode_live_window and so fix crash reported at
2748 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2749 by Juanma Barranquero <lekktu@gmail.com>.
2750 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2751 * font.c (Ffont_at): Likewise.
2753 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2755 * widget.c (resize_cb): New function.
2756 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2757 (EmacsFrameResize): Check if all is up to date before changing frame
2760 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2762 Implement backtrace output for fatal errors on MS-Windows.
2763 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2764 (BACKTRACE_LIMIT_MAX): New macro.
2765 (w32_backtrace): New function.
2766 (emacs_abort): Use w32_backtrace when the user chooses not to
2767 attach a debugger. Update the text of the abort dialog.
2769 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2771 Window-related stuff cleanup here and there.
2772 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2773 Use decode_any_window.
2774 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2775 * xdisp.c (Fformat_mode_line): Likewise.
2776 * font.c (Ffont_at): Use decode_live_window.

2781 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2782 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2785 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2787 Remove pad from struct input_event.
2788 * termhooks.h (struct input_event): Remove padding field.
2790 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2791 member is never cons for a long time. Adjust comment.
2792 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2793 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2794 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2795 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2797 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2799 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2801 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2803 Fix crash when using Emacs as commit editor for git (Bug#12697).
2804 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2805 and it is configured in conf_post.h.
2806 (Fcall_process): Don't invoke both setsid and setpgid; the former
2807 is enough, if it exists.
2808 * callproc.c (Fcall_process, child_setup):
2809 * process.c (create_process): Use setpgid.
2810 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2812 * dispnew.c (init_display): Initialize the foreground group
2813 if we are running a tty display.
2814 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2815 * lisp.h (init_foreground_group): New decl.
2816 * sysdep.c (inherited_pgroup): New static var.
2817 (init_foreground_group, tcsetpgrp_without_stopping)
2818 (narrow_foreground_group, widen_foreground_group): New functions.
2819 (init_sys_modes): Narrow foreground group.
2820 (reset_sys_modes): Widen foreground group.
2822 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2824 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2826 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2828 * minibuf.c (read_minibuf): Restore current buffer since
2829 choose_minibuf_frame calling Fset_frame_selected_window may
2830 change it (Bug#12766).
2832 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2834 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2836 2012-10-30 Kenichi Handa <handa@gnu.org>
2838 * font.c (Ffont_at): If WINDOW is specified and it is not
2839 displaying the current buffer, signal an error.
2841 2012-10-29 Daniel Colascione <dancol@dancol.org>
2843 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2844 In preparation for fixing bug#12739, move these functions from
2847 * coding.h, coding.c: ... to here, and compile them only when
2848 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2849 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2851 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2853 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2854 (timer_loop, getitimer, setitimer): Use it instead of
2855 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2857 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2860 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2862 * nsterm.m (NO_APPDEFINED_DATA): New define.
2863 (last_appdefined_event_data): New variable
2864 (last_appdefined_event): Remove.
2865 (ns_select): Initialize t from last_appdefined_event_data instead
2866 of [last_appdefined_event data1].
2867 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2868 remove last_appdefined_event (Bug#12698).
2870 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2872 * frame.c (x_set_font): Catch internal error.
2874 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2876 Avoid overflow in w32 implementation of interval timers.
2877 When possible, for ITIMER_PROF count only times the main thread
2879 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2880 'volatile ULONGLONG' types. All the other data which was
2881 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2882 (GetThreadTimes_Proc): New typedef.
2883 (w32_get_timer_time): New function, returns a suitable time value
2885 (timer_loop): Enter critical section when accessing ULONGLONG
2886 values of the itimer_data struct, as these accesses are no longer
2887 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2888 Remove unused variable.
2889 (init_timers): Initialize s_pfn_Get_Thread_Times.
2890 (start_timer_thread): Don't assign itimer->caller_thread here.
2891 (getitimer): Assign itimer->caller_thread here.
2892 (setitimer): Always call getitimer to get the value of ticks_now.
2893 (sys_spawnve): Avoid compiler warning about format mismatch.
2895 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2897 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2898 mouse movement events if the menu bar is active. This avoids
2899 producing a busy "hour-glass" cursor by Windows if the mouse
2900 pointer is positioned over a tooltip shown for some menu item.
2902 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2904 Don't assume process IDs fit in int.
2905 * emacs.c (shut_down_emacs) [!DOS_NT]:
2906 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2907 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2908 Use pid_t, not int, to store process IDs, as 'int'
2909 is not wide enough on a few platforms (e.g., AIX and IRIX).
2911 2012-10-23 Kenichi Handa <handa@gnu.org>
2913 The following change is to make face-font-rescale-alist work
2914 correctly for non-ASCII fonts.
2916 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2917 (font_open_for_lface): Handle Vface_font_rescale_alist.
2919 2012-10-23 Chong Yidong <cyd@gnu.org>
2921 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2923 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2927 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2929 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2932 2012-10-21 Glenn Morris <rgm@gnu.org>
2934 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2936 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2938 Port to OpenBSD 5.1.
2939 * frame.c (Fmouse_position, Fmouse_pixel_position):
2940 * xdisp.c (produce_stretch_glyph):
2941 Declare local vars only when they're needed.
2942 This is clearer and avoids a warning on OpenBSD about unused vars.
2943 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2944 This is safer, and avoids OpenBSD warnings about unused vars.
2945 * keyboard.c (record_menu_key): Remove unnecessary decl.
2946 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2947 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2948 as our definition clashes with OpenBSD's.
2949 * xfaces.c (load_face_colors, check_lface_attrs)
2950 (get_lface_attributes_no_remap, get_lface_attributes)
2951 (lface_fully_specified_p, x_supports_face_attributes_p)
2952 (tty_supports_face_attributes_p, face_fontset, realize_face)
2953 (realize_x_face, realize_tty_face):
2954 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2955 merely Lisp_Object *. This is more informative and avoids
2956 a warning on OpenBSD about accessing beyond an object's size.
2958 2012-10-20 Chong Yidong <cyd@gnu.org>
2960 * lread.c (Fload): Doc fix (Bug#12592).
2962 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2964 * font.c (Ffont_at): Fix previous change.
2966 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2968 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2969 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

2982 FD_ISSET (Bug#12668).
2984 2012-10-18 Daniel Colascione <dancol@dancol.org>
2986 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2987 (staticpro): If we run out of staticpro slots, die with an
2988 informative error instead of just calling emacs_abort.
2990 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2992 Fix two flaws reported by Dmitry Antipov.
2993 * window.c (Ftemp_output_buffer_show): Remove.

3035 Lisp_Object values. (Bug#12661)
3037 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer

3074 2012-10-15 Martin Rudalics <rudalics@gmx.at>
3076 * window.c (Fwindow_end): Rewrite check whether cached position
3077 can be used (Bug#12600).

3084 enabled by undefining the symbol "interface", which the platform
3085 headers define to something incompatible.
3087 2012-10-14 Daniel Colascione <dancol@dancol.org>
3089 * image.c (init_tiff_functions, init_imagemagick_functions)
3090 (init_svg_functions): Fix cygw32 build break by using these
3091 functions only when WINDOWSNT _and_ HAVE_NTGUI.

3114 removed or renamed by some other process immediately after Emacs
3115 writes it but before Emacs stats it. Do not assume that stat (or

3149 a file exists. This avoids expensive system calls on MS-Windows.
3152 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.

3203 * marker.c (cached_modiff): EMACS_INT, not int.
3205 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
3206 instead of having a wrong decl.
3207 * nsmenu.m (waiting_for_input): Remove wrong decl.

3211 keyboard.c, keymap.c: Use bool for booleans.

3247 since unsigned is guaranteed to have that behavior and signed is not.
3248 (read_char): Use ptrdiff_t for string length.
3249 (get_input_pending): Remove first argument, since it was always
3250 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3251 and behave as if it had that value. Return new value of
3252 input_pending. All callers changed.
3253 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3254 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3256 * keymap.c (push_key_description): Omit last arg, which was always 1.
3257 All callers changed.
3259 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

3270 initializer for PVEC_NORMAL_VECTOR.
3272 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3274 Clean out old termopts cruft.
3275 * termopts.h (flow_control, meta_key): Remove unused decls.
3276 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
3277 Don't include termopts.h.
3279 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3281 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3283 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3285 * commands.h (immediate_quit): Remove duplicate decl.
3287 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3289 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
3291 (nsfont_open): Remove setting of Vfonts_in_cache.
3292 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3294 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3296 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3297 match what GetLastError returns. Explain why the function is
3300 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3301 'is_tooltip_frame', to avoid confusion with its global namesake.
3303 2012-10-08 Daniel Colascione <dancol@dancol.org>
3305 * xdisp.c (start_hourglass): Call w32_note_current_window when
3306 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3307 build that caused Emacs to display the hourglass cursor forever.
3309 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3310 which is broken under remote desktop, calculate the number of
3311 colors available for a display based on the display's number of
3312 planes and number of bits per pixel per plane. (bug#10397).
3314 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3316 * nsfont.m (Vfonts_in_cache): New variable.
3317 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3318 are used. Add cached fonts to Vfonts_in_cache.
3319 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3321 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3323 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3325 (FONT_H): Define after FRAME_H.
3326 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3327 Update dependencies.
3329 * w32term.c: Remove leftover declaration of keyboard_codepage.
3331 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3333 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3334 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3335 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3336 (GLOBAL_SOURCES): Add cygw32.c.
3337 ($(BLD)/unexw32.$(O)):
3339 ($(BLD)/w32console.$(O)):
3340 ($(BLD)/w32fns.$(O)):
3341 ($(BLD)/w32heap.$(O)):
3342 ($(BLD)/w32menu.$(O)):
3343 ($(BLD)/w32proc.$(O)): Add w32common.h.
3345 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3347 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3349 2012-10-08 Daniel Colascione <dancol@dancol.org>
3351 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3352 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3353 accidental message numbering hole. Change other messages to
3356 * w32select.h (HAVE_W32SELECT): Remove.
3358 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3359 w32common.h instead of w32heap.h.
3361 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3362 (get_allocation_unit, get_processor_type, get_w32_major_version)
3363 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3364 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3365 (OS_NT, os_subtype, cache_system_info): Move declarations to
3368 * w32heap.c: Include w32common.h.
3369 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3370 (w32_minor_version, w32_build_number, w32_subtype):
3371 Remove duplicate definitions.
3373 * w32fns.c: Include w32common.h; include w32heap.h only in
3376 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3377 Use `report_file_error' instead of `error' in order to better
3378 inform users of what went wrong. Increase NTGUI_UNICODE file
3379 dialog box file name length to 32k, the maximum allowed by the NT
3382 * w32common.h: New file.
3383 (ROUND_UP, ROUND_DOWN, get_page_size)
3384 (get_allocation_unit, get_processor_type, get_w32_major_version)
3385 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3386 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3387 (OS_NT, os_subtype, cache_system_info): Move here.
3389 * unexw32.c, unexcw.c: Include w32common.h.
3391 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3392 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3393 to call syms_of_w32select.
3395 * cygw32.h: Remove obsolete EXFUN declarations.
3397 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3399 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3400 of w32inevt.o from SOME_MACHINE_OBJECTS.
3402 2012-10-08 Daniel Colascione <dancol@dancol.org>
3404 * image.c: Permanent fix for JPEG compilation issue --- limit
3405 jpeglib `boolean' redefinition to Cygwin builds.
3407 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3409 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3411 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3414 2012-10-08 Daniel Colascione <dancol@dancol.org>
3416 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3417 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3418 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3419 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3420 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3421 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3422 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3423 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3424 now a supported configuration.
3426 * Makefile.in: consolidate image variables into LIBIMAGE; add
3427 W32_OBJ and W32_LIBS. Compile new files.
3430 (_DebPrint) declare tracing facility for W32 debugging. We need
3431 to unify tracing later.
3433 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3434 unconditional use of W32 Unicode functions. Cygwin runs only on
3435 100% Unicode operating systems.
3437 * cygw32.c: New file. Define Cygwin-specific facilities.
3438 (Fcygwin_convert_path_to_windows)
3439 (Fcygwin_convert_path_from_windows): New user functions for
3440 accessing Cygwin path-munging routines.
3442 * cygw32.h: New file.
3443 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3444 UTF-16LE strings temporarily inside non-Lisp-visible string
3447 (w32_strerror): Just what it says on the tin.
3449 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3450 also run for Cygwin; both systems have the same problem with using
3451 GUI facilities in a forked child. Also call syms_of_cygw32,
3452 syms_of_w32select in correct places.
3454 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3455 needs fork-then-exec for daemon launching.
3457 * font.h: Include frame.h.
3459 * image.c: Use the image library cache machinery only when we're
3460 compiling for native WINDOWSNT; Cygwin can use shared libraries
3461 like any other Unixlike system.
3463 * keyboard.c: Clarify a comment regarding the input loop.
3465 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3466 functions directly instead of trying to detect at runtime that our
3467 host operating system supports them. We make this change for two
3468 reasons: Cygwin lacks support for the multibyte character
3469 conversion functions used by the legacy menu code, and Cygwin
3470 never needs to rely on non-Unicode APIs.
3472 * unexw32.c (hinst): Declare extern.
3474 * w32.c: Change header order;
3475 (w32_strerror): Move to w32fns.c because we need it for
3476 non-WINDOWSNT builds.
3478 * w32.h: Add #error macro to make sure we don't include w32.h for
3479 Cygwin builds. Remove w32select declarations.
3481 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3482 w32fns.c. w32console.c is WINDOWSNT-only.
3484 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3485 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3487 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3488 (w32_major_version, w32_minor_version, w32_build_number)
3489 (os_subtype, sound_type): Define here
3490 (w32_defined_color): Make color parameter const for consistency
3491 with other _defined_color functions.
3492 (w32_createwindow): Unconditionally call w32_init_class instead of
3493 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3494 through the code is complex and unnecessary because class
3495 registration is practically free.
3496 (w32_name_of_message): New EMACSDEBUG-only function.
3497 (Fset_message_beep): Move here
3498 (Fx_open_connection): Require that the display name for Windows be
3499 "w32" for consistency, emacsclient disambiguation, and maybe, one
3500 day, multi-window-system support.
3501 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3502 Cygwin files for W32 GUI facilities, since these clearly don't
3503 expect Cygwin names.
3504 (_DebPrint): Define.
3505 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3506 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3507 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3508 (w32_last_error): Remove.
3510 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3512 * w32heap.c (syspage_mask): Declare here.
3513 (cache_system_info): Remove.
3515 * w32inevt.c (faked_key): Define globally, not statically.
3516 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3517 (w32_console_toggle_lock_key): Move to w32fns.c.
3519 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3521 * w32proc.c (_DebPrint): Move to w32fns.c.
3522 * w32select.c: Include string.h, stdio.h for Cygwin.
3523 * w32select.h: New File.
3525 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3527 (w32_message_fd): New variable. Under Cygwin, holds the file
3528 descriptor the system used to tell us about pending thread
3531 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3532 that prevented compilation under non-WINDOWSNT systems.
3534 (w32_initialize): Open /dev/windows and assign it to
3535 w32_message_fd. Provide w32 feature.
3537 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3538 (WM_EMACS_INPUT_READY): add.
3539 (prepend_msg, w32_message_fd): Declare globally.
3542 (keyboard_handle): Use only when WINDOWSNT.
3543 (notify_msg_ready): New function. Posts a message to the main
3544 thread's message queue under CYGWIN, which wakes up the main
3545 thread from select(2) by making the /dev/windows file descriptor
3546 ready. Under WINDOWSNT, it sets an event the same way the old
3549 (post, prepend_msg): Actually call notify_msg_ready instead of
3550 setting the input event directly.
3552 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3554 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3555 but it still has blocs in it, don't return it to the system,
3556 instead of aborting. (Bug#12402)
3558 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3560 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3562 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3563 MAC_OS_X_VERSION_10_6.
3564 (syms_of_nsterm): Remove comment about Panther and above for
3566 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3567 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3568 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3570 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3571 MAC_OS_X_VERSION_10_4.
3573 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3574 MAC_OS_X_VERSION_10_2.
3576 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3578 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3579 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3581 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3582 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3583 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3584 Remove ns_in_resize check.
3585 (ns_clear_frame_area): Remove resize handle code.
3587 * nsfns.m (ns_in_resize): Remove.
3588 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3589 Remove ns_in_resize check.
3591 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3593 Improve sys_siglist detection.
3594 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3595 defined as a macro, as is done in Solaris.
3596 (sys_siglist_entries): New macro.
3597 (save_strsignal): Use it.
3598 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3599 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3601 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3603 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3604 fullscreen/Fullscreen.
3606 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3607 tobar_height is new.
3609 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3610 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3611 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3612 (windowDidResize:): Check for correct window if old style fullscreen.
3613 Capitalize word in comment. Remove incorrect comment.
3614 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3615 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3616 error in drawing background.
3617 (toggleFullScreen:): Remove comment. Rearrange calls.
3618 Set toolbar values to zero, save old height in tobar_height.
3619 Restore tool bar height when leaving fullscreen.
3620 (canBecomeMainWindow): New function.
3622 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3624 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3626 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3628 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3630 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3631 that time stamps of directories could also be changed.
3632 Don't request the too broad GENERIC_WRITE, only the more restrictive
3633 FILE_WRITE_ATTRIBUTES access rights.
3635 * fileio.c (Fset_file_times): Special-case ignoring errors for
3636 directories only on MSDOS, not on MS-Windows.
3638 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3640 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3642 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3644 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3645 see whether CreateFile failed.
3647 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3649 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3650 to avoid similar races.
3651 * keyboard.c (pending_signals): Now bool, not int.
3653 Port timers to OpenBSD, plus check for timer failures.
3654 OpenBSD problem reported by Han Boetes.
3655 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3657 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3658 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3659 like OpenBSD, which has timer_settime but does not declare it.
3660 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3661 whether to use itimerspec-related primitives. All uses of
3662 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3664 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3666 * profiler.c (handle_profiler_signal): Fix a malloc race
3667 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3669 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3671 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3673 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3675 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3676 consistent with the change in return value of 'safe_strsignal'.
3678 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3680 Prefer plain 'static' to 'static inline' (Bug#12541).
3681 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3682 (bidi_set_sor_type, bidi_push_embedding_level)
3683 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3684 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3685 (bidi_cache_search, bidi_cache_ensure_space)
3686 (bidi_cache_iterator_state, bidi_cache_find)
3687 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3688 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3689 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3690 Now 'static', not 'static inline'.
3692 Count overruns when profiling; change units to ns.
3693 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3694 Give extra weight to samples after overruns, to attempt to count
3695 the time more accurately.
3696 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3697 the underlying primitives nominally do ns.
3698 (Fprofiler_cpu_start): Document the change. Mention that
3699 the sampling intervals are only approximate.
3701 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3703 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3705 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3706 case for the special 0 coding-system.
3708 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3709 (Fmake_overlay): Remove redundant tests.
3710 (fix_start_end_in_overlays): Remove redundant recentering.
3712 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3714 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3715 Update dependencies.
3717 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3719 Fix a malloc race condition involving strsignal.
3720 A signal can arrive in the middle of a malloc, and Emacs's signal
3721 handler can invoke strsignal, which can invoke malloc, which is
3722 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3723 Fix it by altering the signal handler so that it does not invoke
3725 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3726 * process.c (status_message): Use const pointer, in case strsignal
3727 is #defined to safe_strsignal.
3728 * sysdep.c (sys_siglist, init_signals): Always define and
3729 initialize a substitute sys_siglist if the system does not define
3730 one, even if HAVE_STRSIGNAL.
3731 (safe_strsignal): Rename from strsignal. Always define,
3732 using sys_siglist. Return a const pointer.
3733 * syssignal.h (safe_strsignal): New decl.
3734 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3736 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3738 * w32proc.c (timer_loop): Fix code that waits for timer
3739 expiration, to avoid high CPU usage.
3741 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3743 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3744 (sweep_weak_table): Remove redundant prototypes.
3746 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3748 * emacs.c: Move the inclusion of TERM_HEADER after including
3749 windows.h on WINDOWSNT. This avoids compilation problems with
3752 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3754 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3755 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3756 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3757 as the previous version used 'void *'.
3759 * ralloc.c (ROUNDUP): Fix last change.
3760 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3763 * w32proc.c <disable_itimers>: New static flag.
3764 (init_timers): Initialize it to zero, after creating the critical
3765 sections used by the timer threads.
3766 (term_timers): Set to 1 before deleting the critical sections.
3767 (getitimer, setitimer): If disable_itimers is non-zero, return an
3768 error indication without doing anything. Reported by Fabrice
3769 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3770 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3772 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3775 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3776 term_ntproc after all the other bookkeeping, to get timers working
3777 as long as possible.
3779 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3781 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3782 Suggested by Juri Linkov in
3783 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3785 Prefer plain 'static' to 'static inline' (Bug#12541).
3786 With static functions, modern compilers inline pretty well by
3787 themselves; advice from programmers often hurts as much as it helps.
3788 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3789 this change shrinks the text size of the Emacs executable by 1.1%
3790 without affecting CPU significantly in my benchmark.
3791 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3870 (bidi_copy_it): Do the whole copy with a single memcpy.
3871 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3873 Revert the FOLLOW-SYMLINKS change for file-attributes.
3874 Doing it right would require several changes to Tramp, and there's
3875 not enough time to get that tested before the freeze today.
3876 * dired.c (directory_files_internal, Ffile_attributes):
3879 * frame.c (x_report_frame_params): Port better to wider ints.
3880 Do not assume that EMACS_UINT is the same width as uprintmax_t,

3913 * w32.c (init_environment, get_emacs_configuration): Support AMD64
3915 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
3916 compatibility with x64.
3918 * vm-limit.c (lim_data): Now size_t.
3919 (check_memory_limits): Adjust prototypes of real_morecore and
3920 __morecore to receive argument of type ptrdiff_t. Use size_t for

4073 Profiler improvements: more-accurate timers, overflow checks.
4074 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4075 signal.h, setjmp.h. Include systime.h instead.
4076 (saturated_add): New function.

4083 All uses changed to store the new value.
4084 (handle_profiler_signal): Rename from sigprof_handler_1,
4085 for consistency with other handlers. Do not check whether
4086 cpu_log is a hash-table if garbage collecting, since it
4087 doesn't matter in that case.

4089 for consistency with other handlers.
4090 (setup_cpu_timer): New function, with much of what used to be in
4091 Fprofiler_cpu_start. Check for out-of-range argument.
4092 Prefer timer_settime if available, and prefer
4093 thread cputime clocks, then process cputime clocks, then
4094 monotonic clocks, to the old realtime clock. Use make_timeval
4095 to round more-correctly when falling back to setitimer.
4096 (Fprofiler_cpu_start): Use it.
4097 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4098 Don't assume that passing NULL as the 2nd argument of setitimer
4099 is the same as passing a pointer to all-zero storage.
4100 Ignore SIGPROF afterwards.
4101 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4102 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4103 non-fatal signal handlers. Ignore SIGPROF on startup.
4104 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4105 in profiler.c, since sysdep.c now uses it.
4107 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4142 2012-09-27 Paul Eggert <eggert@cs.ucla.edu>
4144 Check more robustly for timer_settime.
4145 * Makefile.in (LIB_TIMER_TIME): New macro.

4161 * character.h (MAYBE_UNIFY_CHAR): Remove.
4162 * charset.c, charset.h (maybe_unify_char): Now static.
4163 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4164 Since this stuff is now private to charset.c, there's no need for
4165 a public macro and no need to inline by hand.
4167 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>

4196 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4198 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4200 Prefer POSIX timers if available.
4201 They avoid a race if the timer is too close to the current time.
4202 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4203 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4204 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4206 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4208 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
4209 CHAR_STRING_ADVANCE.
4210 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
4211 STRING_CHAR_ADVANCE.
4213 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4215 Move Vlibrary_cache to emacs.c and reset before dumping.
4217 * lisp.h (reset_image_types): Declare.
4218 [WINDOWSNT] (Vlibrary_cache): Declare.
4220 * image.c (reset_image_types): New function.
4222 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

4229 * w32.h (Vlibrary_cache): Do not declare.
4231 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4233 * w32proc.c (sys_signal): Handle all signals defined by the
4234 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4235 handlers for signals supported by Windows. Don't override
4236 term_ntproc as the handler for SIGABRT.
4237 (sigaction): Rewrite to call sys_signal instead of duplicating its
4239 (sys_kill): Improve commentary.
4241 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4242 consistency with a signature of a signal handler. All callers
4244 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4245 install term_ntproc as a signal handler for SIGABRT, as that
4246 should be done by the dumped Emacs.
4248 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4250 * w32select.c (term_w32select): Protect against repeated
4251 invocation by setting clipboard_owner to NULL after calling

4255 and term_ntproc to their modified signatures.
4257 * character.c (char_string, string_char): Remove calls to
4258 MAYBE_UNIFY_CHAR. See the discussion starting at
4259 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4262 2012-09-25 Chong Yidong <cyd@gnu.org>
4264 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4266 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4268 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4269 when encountering an unknown bytecode.
4271 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4273 image.c, indent.c: Use bool for booleans.
4274 * dispextern.h (struct image_type): Members valid_p, load, init
4275 now return bool, not int. All uses changed.
4276 * image.c: Omit unnecessary static decls.
4277 (x_create_bitmap_mask, x_build_heuristic_mask):
4278 Return void, not int, since callers don't care about the return value.

4307 Use bool for booleans.
4309 2012-09-24 Chong Yidong <cyd@gnu.org>
4311 * chartab.c (Fset_char_table_default): Obsolete function removed.
4313 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4315 Move pid_t related decls out of lisp.h.
4316 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4317 (interruptible_wait_for_termination):
4318 Move these decls from lisp.h to syswait.h, since they use pid_t.
4319 Needed on FreeBSD; see Herbert J. Skuhra in
4320 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4321 * callproc.c: Include syswait.h.

4338 * nsmenu.m (ns_update_menubar):
4339 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4340 * xfns.c (Fx_show_tip) [USE_GTK]:
4341 Use bool for boolean.
4342 * gtkutil.c (xg_update_frame_menubar):
4343 * xmenu.c (update_frame_menubar):
4344 Return void, not int, since caller ignores return value.
4345 * gtkutil.c (xg_change_toolbar_position):
4348 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4350 * makefile.w32-in (BLOCKINPUT_H): Remove.

4367 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4369 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4370 fatal_error_backtrace.
4372 * w32proc.c (sys_kill): Undo last change: don't do anything when
4373 invoked to deliver SIGABRT to our own process. This is now
4374 handled by emacs_raise.
4376 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4378 * w32term.c (w32_read_socket): Remove leftover reference to
4379 interrupt_input_pending.
4381 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4383 Do not use SA_NODEFER.
4384 Problem reported by Dani Moncayo in
4385 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4387 * sysdep.c (emacs_abort): Do not reset signal handler.
4388 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4389 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4390 wanted even on POSIXish hosts, and it doesn't work on Windows.
4392 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4394 * xterm.c (x_term_init): Call fixup_locale before and after calling
4395 gtk_init (Bug#12392).
4397 2012-09-23 Chong Yidong <cyd@gnu.org>
4399 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4400 Vdynamic_library_alist.
4402 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4403 (Fgnutls_available_p): Caller changed.
4405 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4406 (Flibxml_parse_xml_region): Likewise.
4408 * dispextern.h (struct image_type): Remove arg from init function.
4410 * image.c (Finit_image_library, lookup_image_type)
4411 (define_image_type): Remove now-unneeded second arg.
4412 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4413 (init_tiff_functions, init_gif_functions, init_svg_functions):
4414 Arglist and w32_delayed_load calling convention changed.
4415 (gs_type): Remove init_gs_functions; there is no such function.
4416 (valid_image_p, make_image): Fix caller to lookup_image_type.
4418 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4420 Simplify and avoid signal-handling races (Bug#12471).
4422 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4423 Avoid recursive loop if there's a fatal error in the function itself.
4424 * atimer.c (pending_atimers):
4425 * blockinput.h: Don't include "atimer.h"; no longer needed.
4426 (interrupt_input_pending): Remove. All uses removed.
4427 pending_signals now counts both atimers and ordinary interrupts.
4428 This is less racy than having three separate pending-signal flags.
4429 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4431 Rename from their upper-case counterparts BLOCK_INPUT,
4432 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4433 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4434 This makes it easier to access volatile variables more accurately.
4435 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4436 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4437 that's more reliable if the code is buggy and sets
4438 interrupt_input_blocked to a negative value. All uses changed.
4439 * atimer.c (deliver_alarm_signal):
4440 Remove. No need to deliver this to the parent; any thread can
4441 handle this signal now. All uses replaced by underlying handler.
4442 * atimer.c (turn_on_atimers):
4443 * dispnew.c (handle_window_change_signal):
4444 * emacs.c (handle_danger_signal):
4445 * keyboard.c (kbd_buffer_get_event):
4446 Don't reestablish signal handler; not needed with sigaction.
4447 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4449 Rework to avoid unnecessary accesses to volatile variables.
4450 (UNBLOCK_INPUT_TO): Now a function.
4451 (totally_unblock_input, unblock_input): New decls.
4452 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4453 (init_data): Remove. Necessary stuff now done in init_signal.
4454 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4455 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4456 (fatal_error_code): Remove; no longer needed.
4457 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4458 it doesn't always backtrace. All uses changed. No need to reset
4459 signal to default, since sigaction and/or die does that for us now.
4460 Use emacs_raise (FOO), not kill (getpid (), FOO).
4461 (main): Check more-accurately whether we're dumping.
4462 Move fatal-error setup to sysdep.c
4463 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4464 * gtkutil.c (xg_get_file_name, xg_get_font):
4465 Remove no-longer-needed signal-mask manipulation.
4466 * keyboard.c, process.c (POLL_FOR_INPUT):
4467 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4468 * keyboard.c (read_avail_input): Remove.
4469 All uses replaced by gobble_input.
4470 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4471 (kbd_buffer_store_event_hold, gobble_input):
4472 (record_asynch_buffer_change) [USABLE_SIGIO]:
4473 (store_user_signal_events):
4474 No need to mess with signal mask.
4475 (gobble_input): If blocking input and there are terminals, simply
4476 set pending_signals to 1 and return. All hooks changed to not
4477 worry about whether input is blocked.
4478 (process_pending_signals): Clear pending_signals before processing
4479 them, in case a signal comes in while we're processing.
4480 By convention callers now test pending_signals before calling us.
4481 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4482 New functions, to support changes to blockinput.h.
4483 (handle_input_available_signal): Now extern.
4484 (reinvoke_input_signal): Remove. All uses replaced by
4486 (quit_count): Now volatile, since a signal handler uses it.
4487 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4488 All callers changed. Block SIGINT only if not already blocked.
4489 Clear sigmask reliably, even if Fsignal returns, which it can.
4490 Omit unnecessary accesses to volatile var.
4491 (quit_throw_to_read_char): No need to restore sigmask.
4492 * keyboard.c (gobble_input, handle_user_signal):
4493 * process.c (wait_reading_process_output):
4494 Call signal-handling code rather than killing ourselves.
4495 * lisp.h: Include <float.h>, for...
4496 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4497 (pending_signals): Now volatile.
4498 (syms_of_data): Now const if IEEE floating point.
4499 (handle_input_available_signal) [USABLE_SIGIO]:
4500 (terminate_due_to_signal, record_child_status_change): New decls.
4501 * process.c (create_process): Avoid disaster if memory is exhausted
4502 while we're processing a vfork, by tightening the critical section
4504 (send_process_frame, process_sent_to, handle_pipe_signal)
4505 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4507 (send_process): No need for setjmp/longjmp any more, since the
4508 SIGPIPE stuff is now gone. Instead, report an error if errno
4510 (record_child_status_change): Now extern. PID and W are now args.
4511 Return void, not bool. All callers changed.
4512 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4513 Remove. All uses removed. This bug should be fixed now in a
4515 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4516 and record the child status change directly. This avoids the
4517 need to futz with the signal mask.
4518 (process_fatal_action): Move here from emacs.c.
4519 (emacs_sigaction_flags): New function, containing
4520 much of what used to be in emacs_sigaction_init.
4521 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4522 caught by emacs, to make races less likely.
4523 (deliver_process_signal): Rename from handle_on_main_thread.
4525 (BACKTRACE_LIMIT_MAX): Now at top level.
4526 (thread_backtrace_buffer, threadback_backtrace_pointers):
4528 (deliver_thread_signal, deliver_fatal_thread_signal):
4529 New functions, for more-accurate delivery of thread-specific signals.
4530 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4531 (deliver_arith_signal): Handle in this thread, not
4532 in the main thread, since it's triggered by this thread.
4533 (maybe_fatal_sig): New function.
4534 (init_signals): New arg DUMPING so that we can be more accurate
4535 about whether we're dumping. Caller changed.
4536 Treat thread-specific signals differently from process-general signals.
4537 Block all signals while handling fatal error; that's safer.
4538 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4540 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4541 Ignore SIGPIPE unless batch.
4542 (emacs_backtrace): Output backtrace for the appropriate thread,
4543 which is not necessarily the main thread.
4544 * syssignal.h: Include <stdbool.h>.
4545 (emacs_raise): New macro.
4546 * xterm.c (x_connection_signal): Remove; no longer needed
4547 now that we use sigaction.
4548 (x_connection_closed): No need to mess with sigmask now.
4549 (x_initialize): No need to reset SIGPIPE handler here, since
4550 init_signals does this for us now.
4552 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4554 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4555 background rect may be larger (Bug#12245).
4557 2012-09-23 Chong Yidong <cyd@gnu.org>
4559 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4561 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4563 * .gdbinit: Just stop at fatal_error_backtrace.
4564 See Stefan Monnier's request in
4565 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4566 Remove no-longer-used query of system type.
4568 2012-09-22 Chong Yidong <cyd@gnu.org>
4570 * search.c (Freplace_match): Doc fix (Bug#12325).
4572 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4574 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4575 (Fline_end_position): Doc fix.
4577 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4579 2012-09-22 Chong Yidong <cyd@gnu.org>
4581 * dispextern.h (struct image_type): Add new slot, storing a type
4582 initialization function.
4584 * image.c (define_image_type): Call the image initializer function
4585 if it is defined. Arguments and return value changed.
4586 (valid_image_p, make_image): Callers changed.
4587 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4588 (gif_type, imagemagick_type, svg_type, gs_type):
4589 Add initialization functions.
4590 (Finit_image_library): Call lookup_image_type.
4591 (CHECK_LIB_AVAILABLE): Macro deleted.
4592 (lookup_image_type): Call define_image_type here, rather than via
4593 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4594 (syms_of_image): Move define_image_type calls for xbm_type and
4595 pbm_type to lookup_image_type.
4597 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4599 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4600 'idle_timers' from here ...
4601 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4602 lists, to avoid infloops when the timer does something stupid,
4603 like reinvoke itself with the same or smaller time-out.
4606 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4608 * window.c (Fsplit_window_internal): Handle only Qt value of
4609 Vwindow_combination_limit separately.
4610 (Qtemp_buffer_resize): New symbol.
4611 (Vwindow_combination_limit): New default value.
4614 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4616 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4617 the new overlay string. (Bug#10159)
4619 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4621 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4622 or that fprintf is async-signal-safe. POSIX doesn't require
4625 2012-09-22 Chong Yidong <cyd@gnu.org>
4627 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4630 2012-09-22 Kenichi Handa <handa@gnu.org>
4632 * composite.c (composition_reseat_it): Handle the case that a
4633 grapheme cluster is not covered by a single font (Bug#12352).
4635 2012-09-21 Chong Yidong <cyd@gnu.org>
4637 * image.c (define_image_type): Avoid adding duplicate types to
4638 image_types (Bug#12463). Suggested by Jörg Walter.
4640 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4642 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4643 (print_load_command_name): Add case LC_DATA_IN_CODE.
4644 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4646 2012-09-21 Glenn Morris <rgm@gnu.org>
4648 * eval.c (Frun_hook_with_args_until_success)
4649 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4651 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4653 * fileio.c (Ffile_selinux_context): Only call freecon when
4654 lgetfilecon succeeded.
4655 (Fset_file_selinux_context): Likewise. (Bug#12444)
4657 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4659 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4660 reordering, locate the cursor by calling set_cursor_from_row; if
4661 that fails, clear the desired glyph matrix before returning a
4662 failure indication to the caller. Fixes leaving garbled display
4663 when fast scrolling with a down-key. (Bug#12403)
4664 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4665 scrolling through multibyte text.
4667 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4669 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4670 calling mark_vectorlike since that's the one that marks the window.
4671 (mark_discard_killed_buffers): Mark the final cdr.
4672 * window.h (struct window): Move prev/next_buffers to the
4673 non-standard fields.
4674 * window.c (make_window): Initialize prev/next_buffers manually.
4676 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4678 Omit unused arg EXPECTED from socket hooks.
4679 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4680 * nsterm.m (ns_term_init):
4681 * termhooks.h (struct terminal.read_socket_hook):
4682 * w32inevt.c (w32_console_read_socket):
4683 * w32term.c (w32_read_socket):
4684 * xterm.c (XTread_socket):
4685 Omit unused arg EXPECTED. All callers changed.
4686 (store_user_signal_events): Return void, not int, since callers no
4687 longer care about the return value. All uses changed.
4689 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4691 * w32gui.h (XParseGeometry): Do not declare.
4693 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4695 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4696 Ignore 'expected'. See Eli Zaretskii in
4697 <http://bugs.gnu.org/12471#8> (last line).
4699 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4700 (XParseGeometry): Now static. Substitute extremal values for
4701 values that are out of range.
4703 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4705 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4707 * nsfns.m (XParseGeometry): Remove.
4708 (Fx_create_frame): Call x_set_offset to correctly interpret
4709 top_pos in geometry.
4711 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4712 (Fx_parse_geometry): If there is a space in string, call
4713 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4715 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4717 * search.c (scan_buffer): Use character positions in calls to
4718 region_cache_forward and region_cache_backward, not byte
4719 positions. (Bug#12196)
4721 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4722 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4724 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4725 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4726 emacs_blocked_malloc, now deleted.
4728 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4730 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4731 The workaround was for improving performance on Solaris 2.4, but
4732 is getting in the way now. Emacs will still work if someone is
4733 still running Solaris 2.4 in a museum somewhere; Sun dropped
4734 support for Solaris 2.4 in 2003.
4735 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4736 * process.c (create_process) [HAVE_WORKING_VFORK]:
4737 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4738 since Emacs no longer uses vfork on that platform.
4740 2012-09-17 Glenn Morris <rgm@gnu.org>
4742 * emacs.c: Use COPYRIGHT.
4744 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4746 Remove configure's --without-sync-input option (Bug#12450).
4747 When auditing signal-handling in preparation for cleaning it up,
4748 I found that SYNC_INPUT has race conditions and would be a real
4749 pain to fix. Since it's an undocumented and deprecated
4750 configure-time option, now seems like a good time to remove it.
4751 Also see <http://bugs.gnu.org/11080#16>.
4752 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4753 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4754 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4755 (malloc_hysteresis):
4756 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4757 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4758 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4759 (dont_register_blocks, bytes_used_when_reconsidered)
4760 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4761 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4762 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4763 Remove. All uses removed.
4764 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4765 implementation, one that depends on whether the new macro
4766 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4768 * atimer.c (run_timers, handle_alarm_signal):
4769 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4770 (handle_async_input, process_pending_signals)
4771 (handle_input_available_signal, init_keyboard):
4772 * nsterm.m (ns_read_socket):
4773 * process.c (wait_reading_process_output):
4774 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4775 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4777 * xterm.c (XTread_socket):
4779 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4780 * eval.c (handling_signal): Remove. All uses removed.
4781 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4782 All uses replaced with the SYNC_INPUT version.
4783 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4785 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4788 * font.c (Ffont_shape_gstring): Remove unused local.
4790 2012-09-16 Glenn Morris <rgm@gnu.org>
4792 * Makefile.in (clean): No longer run nextstep's clean.
4794 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4796 (ns-app): Move here from ns.mk, and simplify.
4797 (clean): Simplify nextstep entry.
4798 * ns.mk: Remove file.
4800 2012-09-17 Kenichi Handa <handa@gnu.org>
4802 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4803 not covert the last few charactes.
4805 2012-09-16 Kenichi Handa <handa@gnu.org>
4807 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4808 here, but just check the validity of glyphs in the glyph-string.
4810 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4812 * window.c (Fwindow_parameter, Fset_window_parameter):
4813 Accept any window as argument (Bug#12452).
4815 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4817 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4818 to ns_term_init to avoid memory leak.
4820 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4821 explicit retain/release.
4822 (ns_term_init): Only allow one display. Initialize outerpool and
4825 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4827 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4828 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4829 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4830 the Microsoft problem in a different way, by altering ../nt/config.nt.
4832 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4847 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4848 by lisp.h. This completes removal of setjmp.h inclusion
4849 erroneously announced in the previous commit. (Bug#12446)
4851 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4854 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4855 not defined as a macro. The latter happens on MS-Windows.
4858 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4860 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4861 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4862 Some instances of '#include <setjmp.h>' removed, if the
4863 only reason for the instance was because "lisp.h" was included.
4864 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4865 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4866 and _longjmp with the new symbols. Emacs already uses _setjmp if
4867 available, so this change affects only POSIXish hosts that have
4868 sigsetjmp but not _setjmp, such as some versions of Solaris and
4869 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4870 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4871 (png_load_body) [HAVE_PNG]:
4872 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4873 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4874 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4875 since PNG requires jmp_buf. This is the only exception to the
4876 general rule that we now use sys_setjmp and sys_longjmp.
4877 This exception is OK since this code does not change the signal
4878 mask or longjmp out of a signal handler.
4880 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4882 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4883 Include "syssignal.h", for 'main_thread'.
4885 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4887 Avoid out-of-range marker position (Bug#12426).
4888 * insdel.c (replace_range, replace_range_2):
4889 Adjust markers before overlays, as suggested by comments.
4890 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4891 Remove redundant check before calling offset_intervals.
4893 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4895 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4896 current buffer (Bug#12387).
4898 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4900 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4902 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4904 Use a more backwards-compatible timer format (Bug#12430).
4905 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4906 vector element, not from the 4th, since PSECS is now at the end.
4907 (Fcurrent_idle_time): Doc fix.
4909 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4911 Function to mark objects and remove killed buffers at once.
4912 * alloc.c (discard_killed_buffers): Rename to ...
4913 (mark_discard_killed buffers) ... new name. Add marking
4914 of remaining objects. Fix comment. Adjust users.
4915 (mark_object): Do not touch frame buffer lists here.
4916 * frame.c (delete_frame): Reset frame buffer lists here.
4918 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4920 Better workaround for GNOME bug when --enable-gcc-warnings.
4921 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4922 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4923 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4925 Simplify SIGIO usage (Bug#12408).
4926 The code that dealt with SIGIO was crufty and confusing, e.g., it
4927 played tricks like "#undef SIGIO" but these tricks were not used
4928 consistently. Simplify mostly by not #undeffing standard symbols,
4929 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4930 or not as we please) rather than "defined SIGIO" (standard symbol
4931 that we probably shouldn't #undef).
4932 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4933 Modules that need it can include it.
4934 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4935 * dispextern.h (ignore_sigio): New decl.
4936 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4937 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4938 * emacs.c (shut_down_emacs):
4939 * keyboard.c (kbd_buffer_store_event_hold):
4940 Use ignore_sigio rather than invoking 'signal' directly.
4941 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4943 (FIONREAD, SIGIO): Do not #undef.
4944 (tty_read_avail_input): Use #error rather than a syntax error.
4945 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4946 for I_PIPE, used by SETUP_SLAVE_PTY.
4947 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4948 * sysdep.c (croak): Remove; no longer needed. This bit of
4949 temporary code, with Fred N. Fish's comment that it's temporary,
4950 has been in Emacs since at least 1992!
4951 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4952 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4953 * syssignal.h (croak): Remove decl.
4954 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4955 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4956 now that we're termios-only.
4957 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4958 * term.c (dissociate_if_controlling_tty): Use #error rather than
4961 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4962 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4963 to work around GNOME bug 683906.
4964 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4965 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4966 This works around GCC bug 54561.
4968 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4970 More fixes for 'volatile' and setjmp/longjmp.
4971 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4972 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4973 (png_load_body) [HAVE_PNG]:
4974 (jpeg_load_body) [HAVE_JPEG]:
4975 New function, with most of the old parent function's body.
4976 (png_load) [HAVE_PNG]:
4977 (jpeg_load) [HAVE_JPEG]:
4978 Invoke the new function, to avoid longjmp munging our locals.
4979 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4980 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4981 longjmp is passed 2, as the C standard doesn't guarantee this.
4982 Instead, store the failure code into mgr->failure_code.
4984 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4986 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4987 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4988 (syms_of_keyboard): Remove support for unread-command-char.
4990 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4992 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4993 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4994 violation. (Bug#12426)
4996 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4998 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5000 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5002 * eval.c: Add `inhibit-debugger'.
5003 (Qinhibit_debugger): New symbol.
5004 (call_debugger): Bind it instead of Qdebug_on_error.
5005 (maybe_call_debugger): Test Vinhibit_debugger.
5006 (syms_of_eval): Define inhibit-debugger.
5007 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5008 (syms_of_xdisp): Remove inhibit-debug-on-message.
5010 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5012 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5013 If a nonvolatile local variable is written before a _longjmp to
5014 the frame containing the variable, and is read after the _longjmp,
5015 the value read is indeterminate. Some local variables of type
5016 'struct handler' and 'struct catchtag' are used in this way, so
5017 mark each of their slots as volatile if the slot can be set before
5018 _longjmp and read afterwards.
5019 * lisp.h (struct handler): var and chosen_clause are now volatile.
5020 (struct catchtag): val, next, and pdlcount are now volatile.
5022 * bidi.c (bidi_push_it, bidi_pop_it):
5023 * fns.c (copy_hash_table):
5024 * image.c (define_image_type):
5025 * keyboard.c (kbd_buffer_store_event_hold):
5026 * process.c (Fprocess_send_eof):
5027 * xfaces.c (x_create_gc) [HAVE_NS]:
5028 * xgselect.c (xg_select):
5029 Prefer assignment to memcpy when either will do.
5031 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5032 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5033 time an item is removed. No need to mark this function 'inline';
5034 the compiler knows better than we do.
5036 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5038 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5039 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5040 to change_frame_size (Bug#12388).
5041 (windowDidResize:): Pass YES to updateFrameSize.
5043 * nsterm.h: Add delay parameter to updateFrameSize.
5045 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5047 Discard killed buffers from deleted window and frame objects.
5048 This reduces an amount of references to killed buffers and
5049 helps GC to reclaim them faster.
5050 * alloc.c (discard_killed_buffers): New function.
5051 (mark_object): Use it for deleted windows and frames.
5052 (mark_object): If symbol's value is set up for a killed buffer
5053 or deleted frame, restore its global binding.
5054 * data.c (swap_in_global_binding): Add GC notice.
5055 (swap_in_symval_forwarding): Use convenient set_blv_where.
5056 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5057 * window.h: ... to here.
5059 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5061 Convenient macro to check whether the buffer is live.
5062 * buffer.h (BUFFER_LIVE_P): New macro.
5063 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5064 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5066 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5068 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5069 composition cases (Bug#12364).
5071 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5072 overhang of succeeding glyphs overlapping box cursor.
5074 * w32term.c (x_draw_glyph_string): Likewise.
5076 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5078 Simplify, document, and port floating-point (Bug#12381).
5079 The porting part of this patch fixes bugs on non-IEEE platforms
5080 with frexp, ldexp, logb.
5081 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5083 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5084 support, by removing commented-out code and briefly listing the
5085 C89 functions excluded. The commented-out stuff was confusing
5086 maintenance, e.g., we thought we needed cbrt but it was commented out.
5087 (logb): Remove decl; no longer needed.
5088 (isfinite): New macro, if not already supplied.
5089 (isnan): Don't replace any existing macro.
5090 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5091 are present on all C89 platforms.
5092 (Ffrexp): Do not special-case zero, as frexp does the right thing
5094 (Flogb): Do not use logb, as it doesn't have the desired meaning
5095 on hosts that use non-base-2 floating point. Instead, stick with
5096 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5097 frexp, to avoid getting an unspecified result.
5099 * xdisp.c (Qinhibit_debug_on_message): Now static.
5101 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5103 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5104 NSBezierPath (Bug#12131).
5106 2012-09-10 Chong Yidong <cyd@gnu.org>
5108 * fns.c (Fdelq, Fdelete): Doc fix.
5110 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5112 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5113 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5115 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5117 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5118 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5121 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5123 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5124 left fringe if the window has a left margin. This avoids leaving
5125 traces of the cursor because its leftmost pixel is not drawn over.
5127 * dispnew.c (update_window_line): When the left margin area of a
5128 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5129 that screen line. (Bug#12277)
5131 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5133 Assume C89 or later for math functions (Bug#12381).
5134 This simplifies the code, and makes it a bit smaller and faster,
5135 and (most important) makes it easier to clean up signal handling
5136 since we can stop worring about floating-point exceptions in
5137 library code. That was a problem before C89, but the problem
5138 went away many years ago on all practical Emacs targets.
5139 * data.c, image.c, lread.c, print.c:
5140 Don't include <math.h>; no longer needed.
5141 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5142 might be autoconfigured, as that never happens.
5144 * doprnt.c (DBL_MAX_10_EXP):
5145 * print.c (DBL_DIG):
5146 Remove. C89 or later always defines these.
5147 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5148 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5149 (arith_error, domain_error, domain_error2):
5150 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5151 no longer needed -- we simply return what C returns. All uses removed.
5152 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5154 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5155 Remove. All uses expanded, as these macros are no longer used
5156 more than once and are now more trouble than they're worth.
5157 (Ftan): Use tan, not sin / cos.
5158 (Flogb): Assume C89 frexp.
5159 (fmod_float): Assume C89 fmod.
5160 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5161 (init_floatfns): Remove. All uses removed.
5163 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5165 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5166 compositeToPoint for OSX < 10.6 (Bug#12390).
5168 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5170 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5171 This produces more-accurate results.
5173 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5175 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5176 changes (Bug#12088).
5178 2012-09-08 Chong Yidong <cyd@gnu.org>
5180 * syntax.c (Fstring_to_syntax): Doc fix.
5182 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5184 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5185 in the internal border.
5186 (x_set_window_size): Remove static variables and their usage.
5187 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5188 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5189 Remove fringe/internal border adjustment (Bug#11052).
5190 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5191 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5192 (ns_fix_rect_ibw): Remove.
5193 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5194 (ns_dumpglyphs_box_or_relief): Ditto.
5195 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5197 (ns_dumpglyphs_image): Ditto.
5198 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5200 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5201 their usage. Add fringe_extended_p and its use as in other terms.
5202 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5203 scroll bar was removed.
5204 (updateFrameSize): New function.
5205 (windowDidResize): Move code to updateFrameSize and call it.
5207 * nsterm.h (EmacsView): Add updateFrameSize.
5209 2012-09-07 Chong Yidong <cyd@gnu.org>
5211 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5213 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5215 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5217 More signal-handler cleanup (Bug#12327).
5218 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5219 Problem introduced when merging patches. Noted by Eli Zaretskii in
5220 <http://bugs.gnu.org/12327#67>.
5221 * floatfns.c: Comment fix.
5222 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5223 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5224 and anyway the declaration is harmless even if SIGDANGER is not defined.
5225 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5226 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5227 source files not surprisingly expected syssignal.h to define, or
5228 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5229 Include <sys/ioctl.h>, for FIONREAD.
5230 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5231 This eliminates a problem whereby other files mysteriously had
5232 to include "syssignal.h" before including "systty.h" if they
5233 wanted to use "#ifdef SIGIO".
5235 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5237 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5239 * w32.c (sigemptyset): Empty the set.
5240 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5242 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5244 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5246 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5247 (mark_object): Likewise for frame objects.
5249 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5251 * syssignal.h (handle_on_main_thread): Always declare,
5252 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5253 This ports to platforms without HAVE_PTHREAD.
5255 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5257 Signal-handler cleanup (Bug#12327).
5258 Emacs's signal handlers were written in the old 4.2BSD style with
5259 sigblock and sigmask and so forth, and this led to some
5260 inefficiencies and confusion. Rewrite these to use
5261 pthread_sigmask etc. without copying signal sets around. Also,
5262 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5263 'signal', and instead use functions that do not attempt to take
5264 over the system name space. This patch causes Emacs's text
5265 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5266 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5267 Do not include <signal.h> or "syssignal.h", as these
5268 modules do not use signals.
5269 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5270 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5271 Do not include <signal.h>, as "syssignal.h" does that for us now.
5272 * atimer.c (sigmask_atimers): New function.
5273 (block_atimers, unblock_atimers): New functions,
5274 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5276 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5277 no longer needed here.
5278 * emacs.c (main): Inspect existing signal handler with sigaction,
5279 so that there's no need to block and unblock SIGHUP.
5280 * sysdep.c (struct save_signal): New member 'action', replacing
5281 old member 'handler'.
5282 (save_signal_handlers, restore_signal_handlers):
5283 Use sigaction instead of 'signal' to save and restore.
5284 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5285 New function. All users of 'signal' modified to use set_sighandler
5286 if they're writeonly, and to use sys_signal if they're read+write.
5287 (emacs_sigaction_init, forwarded_signal): New functions.
5288 (sys_signal): Remove. All uses replaced by calls to sigaction
5289 and emacs_sigaction_init, or by direct calls to 'signal'.
5290 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5291 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5292 all uses replaced by pthread_sigmask etc. calls.
5293 * syssignal.h: Include <signal.h>.
5294 (emacs_sigaction_init, forwarded_signal): New decls.
5295 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5296 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5297 (sigmask, sys_sigmask): Remove; no longer needed.
5298 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5299 (sigblock, sigunblock, sigfree):
5300 (sigsetmask) [!defined sigsetmask]:
5301 Remove. All uses replaced by pthread_sigmask.
5302 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5303 no longer need to be replaced, and its typical old uses
5304 are now done via emacs_sigaction_init and sigaction.
5305 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5306 (sys_sigdel): Remove; unused.
5307 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5309 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5311 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5312 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5314 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5316 Explicitly mark buffer_defaults and buffer_local_symbols.
5317 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5318 mark_local_symbols here.
5319 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5320 since special buffers aren't marked here any more.
5321 (allocate_buffer): Chain new buffer with all_buffers here...
5322 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5324 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5325 (syms_of_buffer): Remove staticpro of the above.
5326 (init_buffer_once): Set names for buffer_defaults and
5327 buffer_local_symbols.
5329 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5331 Use bool for booleans in font-related modules.
5332 * font.c (font_intern_prop, font_style_to_value)

5337 (fontset_find_font, Fset_fontset_font)
5338 (face_suitable_for_char_p) [0]:
5339 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5340 (ftfont_open, ftfont_text_extents, ftfont_check_otf):

5343 * nsfont.m (nsfont_draw):
5344 * w32font.c (w32font_draw):
5345 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5346 Use bool for booleans.
5347 * font.h: Adjust to above API changes.
5348 (struct font, struct font_driver, struct font_driver_list):
5349 Use bool for booleans.
5350 (struct font): Remove useless member encoding_type.
5352 * fontset.c, xftfont.c: Omit unnecessary static decls.
5354 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5356 * alloc.c (mark_object): Revert window marking code
5357 since it's unsafe for the Fset_window_configuration.
5359 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5361 Fix race conditions with signal handlers and errno (Bug#12327).
5362 Be more systematic about preserving errno whenever a signal
5363 handler returns, even if it's not in the main thread. Do this by
5364 renaming signal handlers to distinguish between signal delivery
5365 and signal handling. All uses changed.
5366 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5367 * data.c (deliver_arith_signal): Rename from arith_error.
5368 * dispnew.c (deliver_window_change_signal): Rename from
5369 window_change_signal.
5370 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5371 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.

5373 input_available_signal.
5374 (deliver_user_signal): Rename from handle_user_signal.
5375 (deliver_interrupt_signal): Rename from interrupt_signal.
5376 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5377 (deliver_child_signal): Rename from sigchld_handler.
5378 * atimer.c (handle_alarm_signal):
5379 * data.c (handle_arith_signal):
5380 * dispnew.c (handle_window_change_signal):
5381 * emacs.c (handle_fatal_signal, handle_danger_signal):
5382 * keyboard.c (handle_input_available_signal):
5383 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5384 * process.c (handle_pipe_signal, handle_child_signal):
5385 New functions, with the actual signal-handling code taken from the
5386 original respective signal handlers, sans the sporadic attempts to
5387 preserve errno, since that's now done by handle_on_main_thread.
5388 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5389 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5390 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5392 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5393 Move initialization of main_thread to sysdep.c's init_signals.
5394 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5395 our usage, and simplifies the mainline code.
5396 (record_child_status_change): New static function, as a helper
5397 for handle_child_signal, and with most of the old child handler's
5399 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5400 (handle_child_signal): Use the above.
5401 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5402 Moved here from emacs.c.
5403 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5404 code moved here from emacs.c's main function.
5405 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5406 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5407 This lets callers save and restore errno properly.
5409 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5411 Remove redundant or unused things here and there.
5412 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5413 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5414 * editfns.c (Fcompare_buffer_substrings): Likewise.
5415 * frame.h (struct terminal, struct font_driver_list):
5416 Remove redundant declarations.
5417 * window.h (Qleft, Qright): Likewise.

5423 (mark_object): Likewise for windows and frames.
5425 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5427 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5428 buffer_defaults and buffer_local_symbols as valid objects.
5429 Return special value to denote them.
5431 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>

5435 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5436 (file_name_absolute_p, Fsubstitute_in_file_name):

5440 (Fwrite_region, build_annotations, a_write, e_write)
5442 * filelock.c (boot_time_initialized, get_boot_time)
5443 (get_boot_time_1, lock_file_1, within_one_second):
5444 * floatfns.c (in_float):
5445 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5446 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5447 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5448 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5449 * window.c (compare_window_configurations):
5450 Use bool for booleans.
5451 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5452 (Fdefault_file_modes): Now mode_t, not int, for modes.
5453 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5454 (internal_delete_file): Now returns void, not a (boolean) int,
5455 since nobody was looking at the return value.
5456 * lisp.h, window.h: Adjust to above API changes.
5458 * xdisp.c (set_message): Simplify and reindent last change.
5460 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5462 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5464 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5466 * eval.c (call_debugger): Make the function non-static so that we
5467 can call it from set_message.
5469 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5470 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5472 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5474 Give more-useful info on a fatal error (Bug#12328).
5475 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5476 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5477 of doing the work ourselves.
5478 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5479 do most of the work.
5480 (fatal_error_backtrace): New function, taken from the guts
5481 of the old fatal_error_signal, but with a new option to output
5483 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5484 info about the signal than just its number.
5485 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5486 * sysdep.c: Include <execinfo.h>
5487 (emacs_backtrace): New function, taken partly from the previous
5488 code of the 'die' function.
5489 (emacs_abort): Call fatal_error_backtrace rather than abort.
5491 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5493 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5494 eager (load-time) macro-expansion.
5495 * lisp.mk (lisp): Add macroexp.
5497 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5499 Simplify redefinition of 'abort' (Bug#12316).
5500 Do not try to redefine the 'abort' function. Instead, redo
5501 the code so that it calls 'emacs_abort' rather than 'abort'.
5502 This removes the need for the NO_ABORT configure-time macro
5503 and makes it easier to change the abort code to do a backtrace.
5504 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5505 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5506 Remove; sysdep.c's emacs_abort now takes its place.
5507 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5508 'abort' changed to use 'emacs_abort'.
5509 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5510 (abort) [!defined abort]: Rename to ...
5511 (emacs_abort): ... new name.
5512 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5513 the place of the old 'abort' in emacs.c.
5514 * w32.c, w32fns.c (abort): Do not #undef.
5515 * w32.c (emacs_abort): Rename from w32_abort.
5517 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5519 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5520 offsets[j].dv, since the y axis of the screen coordinates points
5521 down, while the y axis of the font definition coordinates points
5522 up. This fixes display of Arabic diacritics such as KASRA and
5523 KASRATAN. (Bug#11860)
5525 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5527 Be more systematic about _setjmp vs setjmp.
5528 * alloc.c (test_setjmp, mark_stack):
5529 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5530 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5531 (png_load, my_error_exit, jpeg_load):
5532 * process.c (send_process_trap, send_process):
5533 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5534 The underscored versions are up to 30x faster on some hosts.
5535 Formerly, the code used setjmp+longjmp sometimes and
5536 _setjmp+_longjmp at other times, with no particular reason to
5537 prefer setjmp+longjmp.
5539 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5541 Fix minor problem found by static checking.
5542 * buffer.c (Fdelete_all_overlays): Return nil.
5544 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5546 * buffer.c (Fdelete_all_overlays): New function.
5548 2012-09-03 Chong Yidong <cyd@gnu.org>

5568 EXCLUDE_SUBRS_P. All callers changed.
5569 * dispextern.h, lisp.h: Reflect above API changes.
5570 * firstfile.c (dummy): Use the address of 'main', whose signature
5571 won't change, instead of the address of 'initialize', whose
5572 signature just changed from int to bool.
5573 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5574 * msdos.c (fatal_error_in_progress): ... from here.
5575 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5577 (redisplay_internal, unwind_redisplay): Simply clear
5578 REDISPLAYING_P when unwinding, instead of saving its previous,
5579 always-false value and then restoring it.
5581 Clean up some extern decls.
5582 Mostly, this hoists extern decls out of .c files and into .h files.
5583 That way, we're more likely to catch errors if the interfaces change.
5584 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5585 declare xg_mark_data.
5586 * dispextern.h (x_frame_parm_handlers):
5588 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

5604 * xfont.c (x_clear_errors):
5605 * xterm.c (x_frame_parm_handlers):
5606 Remove now-redundant extern decls.
5607 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5608 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5610 * xfaces.c: Remove unnecessary static decls.
5611 * xterm.c (updating_frame): Remove decl of nonexistent object.
5613 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5614 when building globals.h, as the objects that are not built on
5615 this host are not needed to compile C files on this host.
5617 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5619 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5667 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5669 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5670 more than one grapheme cluster passed to the shaper: compute the
5671 offset adjustment values separately for each cluster. (Bug#11860)
5673 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5674 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5675 about implicit conversions from integer to pointer.
5677 2012-09-01 Daniel Colascione <dancol@dancol.org>
5679 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5680 system used too early.
5682 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5684 Better seed support for (random).

5733 window system declarations.
5735 * frame.h: Move common functions here: set_frame_menubar,
5736 x_set_window_size, x_sync, x_get_focus_frame,
5737 x_set_mouse_position, x_set_mouse_pixel_position,
5738 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5762 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5764 Remove mark_ttys function and fix tty_display_info initialization.
5765 * lisp.h (mark_ttys): Remove prototype.
5766 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5767 to mark_ttys because all possible values of 'top_frame' slot are
5768 the frames which are reachable from Vframe_list.
5769 * term.c (mark_ttys): Remove.
5770 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5772 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

5799 * lread.c (init_lread): For out-of-tree builds, only add the
5800 source directory's site-lisp dir to the load-path if it exists,
5801 consistent with in-tree builds. (Bug#12302)
5803 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

5822 Handle click on close button as quit.
5824 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5825 Add window_closed and button_values. Add void as return value for
5826 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5827 Add process_dialog as new member.
5829 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5831 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5935 * dired.c (file_name_completion):
5936 * process.h (fd_callback):
5937 Omit int (actually boolean) argument. It wasn't being used.
5939 * composite.h, lisp.h: Reflect above API changes.
5941 * cmds.c, coding.c: Use bool for booleans.
5942 * cmds.c (move_point, Fself_insert_command):
5943 * coding.h (struct composition status, struct coding_system):
5944 * coding.c (detect_coding_utf_8, encode_coding_utf_8)

5960 (Funencodable_char_position, code_convert_region)
5961 (code_convert_string, code_convert_string_norecord)
5962 (Fset_coding_system_priority):
5963 * fileio.c (Finsert_file_contents):
5964 Use bool for booleans.
5965 * coding.h, lisp.h: Reflect above API changes.
5966 * coding.c: Remove unnecessary static function decls.
5967 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5968 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5969 not a boolean 'int', since callers never look at the return value.
5970 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5971 * coding.h (decoding_buffer_size, encoding_buffer_size)
5972 (emacs_mule_string_char): Remove unused extern decls.
5973 (struct iso_2022_spec, struct coding_system):
5974 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5975 (struct emacs_mule_spec): Remove unused field 'full_support'.
5976 All initializations removed.
5977 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5979 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5981 Fix spare memory change (Bug#12286).
5982 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5983 (valid_lisp_object_p): Likewise.
5985 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5987 * window.c (Fset_window_configuration): Record any window's old
5988 buffer if it's replaced (see Bug#8789). If the new current
5989 buffer doesn't appear in the selected window, go to its old
5992 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5994 Special MEM_TYPE_SPARE to denote reserved memory.
5995 * alloc.c (enum mem_type): New memory type.
5996 (refill_memory_reserve): Use new type for spare memory.
5997 This prevents live_cons_p and live_string_p from incorrect
5998 detection of uninitialized objects from spare memory as live.
6000 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6003 * Makefile.in (.PHONY): versioclean -> versionclean.
6005 Remove unused external symbols.
6006 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6007 * window.c (Qwindow_valid_p, decode_valid_window):
6008 Now static, not extern.
6009 * data.c (Qinterval): Remove; unused.
6010 (syms_of_data): Do not define 'interval'.
6011 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6012 * window.h (decode_valid_window):
6015 * character.c, charset.c, chartab.c: Use bool for booleans.
6016 * character.c (lisp_string_width, string_count_byte8)
6017 (string_escape_byte8):
6018 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6019 (load_charset_map_from_file, map_charset_chars)
6020 (Fdefine_charset_internal, define_charset_internal)
6021 (Fdeclare_equiv_charset, find_charsets_in_text)
6022 (Ffind_charset_region, char_charset, Fiso_charset):
6023 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6024 (sub_char_table_set, sub_char_table_set_range)
6025 (char_table_set_range, optimize_sub_char_table)
6026 (map_sub_char_table):
6027 Use bool for boolean.
6028 * character.c (str_to_unibyte): Omit last boolean argument; it was
6029 always 0. All callers changed.
6030 * character.h, charset.h: Adjust to match previous changes.
6031 * character.h (char_printable_p): Remove decl of nonexistent function.
6032 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6033 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6034 are all boolean, so make them single-bit bitfields.
6036 * lisp.h (ASET): Remove attempt to detect side effects.
6037 It was meant to be temporary and it often doesn't work,
6038 because when IDX has side effects the behavior of IDX==IDX
6039 is undefined. See Stefan Monnier in
6040 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6042 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6044 * lisp.h (functionp): New function (extracted from Ffunctionp).
6045 (FUNCTIONP): Use it.
6046 * eval.c (Ffunctionp): Use it.
6048 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6050 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6051 as that's faster and simpler than static storage. Don't bother
6052 with the g_main_context_query overhead if g_main_context_pending
6053 says no events are pending.
6054 (gfds, gfds_size): Remove these static vars.
6055 (xgselect_initialize): Remove; no longer needed.
6056 All uses and decls removed.
6058 * emacs.c (fatal_error_signal_hook): Remove.
6059 All uses removed. This leftover from old code was always 0.
6061 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6062 * casefiddle.c (casify_object, casify_region):
6063 * casetab.c (set_case_table):
6064 * category.c, category.h (word_boundary_p):
6065 * category.h (CHAR_HAS_CATEGORY):
6066 Use bool for booleans, instead of int.
6068 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6070 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6072 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6074 On assertion failure, print backtrace if available.
6075 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6076 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6077 * Makefile.in (LIB_EXECINFO): New macro.
6080 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6081 * bytecode.c (exec_byte_code):
6082 * callint.c (check_mark, Fcall_interactively):
6083 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6084 (getenv_internal, sync_process_alive, call_process_exited):
6085 * lisp.h (USE_SAFE_ALLOCA):
6086 Use bool for booleans, instead of int.
6087 * lisp.h, process.h: Adjust prototypes to match above changes.
6088 * callint.c (Fcall_interactively): Don't assume the mark's
6089 offset fits in 'int'.
6091 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6093 * buffer.c, buffer.h: Use bool for boolean.
6094 * buffer.c (reset_buffer_local_variables)
6095 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6096 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6097 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6098 (overlay_touches_p, overlay_strings, Foverlay_put)
6099 (report_overlay_modification, call_overlay_mod_hooks):
6100 (mmap_enlarge, mmap_set_vars):
6101 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6102 Use bool for booleans, instead of int.
6103 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6104 since the 1-or-0 return value is always ignored anyway.
6105 (mmap_initialized_p):
6106 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6107 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6109 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6111 * bidi.c: Use bool for boolean.
6112 This is a bit more readable, and makes the text segment of bidi.o
6113 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6114 Presumably it's faster too.
6115 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6117 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6118 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6119 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6120 (bidi_explicit_dir_char, bidi_level_of_next_char)
6121 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6122 Use bool for booleans, instead of int.
6123 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6124 (bidi_unshelve_cache): Adjust decls to match code.
6126 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6128 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6131 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6133 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6134 * atimer.h: Include <stdbool.h>.
6136 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6138 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6139 compile time tests instead of run time tests on systems that do
6141 (FRAME_MAC_P): Remove leftover from deleted code.
6142 * frame.c (syms_of_frame): Remove leftover from deleted code.
6144 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6146 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6148 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6150 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6151 Otherwise, the compiler complains about (A?B:C) where B is void
6152 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6153 (fontset_add): Return void, for FONTSET_ADD.
6155 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6157 * alloc.c: Use bool for booleans.
6158 (gc_in_progress, abort_on_gc)
6159 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6160 (dont_register_blocks) [GC_MALLOC_CHECK]:
6161 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6162 (check_string_bytes, make_specified_string, memory_full)
6163 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6164 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6165 (mark_stack, valid_pointer_p, make_pure_string)
6166 (Fgarbage_collect, survives_gc_p, gc_sweep):
6167 Use bool for booleans, instead of int.
6168 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6169 Remove unused local.
6170 * alloc.c (PURE_POINTER_P):
6171 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6172 * editfns.c (Fformat):
6173 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6175 * fns.c (sweep_weak_table):
6176 * lisp.h (suppress_checking, push_message, survives_gc_p)
6177 (make_pure_string, gc_in_progress, abort_on_gc):
6178 * lread.c (readchar, read1):
6179 * print.c (Fprin1_to_string):
6180 * xdisp.c (push_message):
6181 Use bool for booleans affected directly or indirectly by
6184 Make recently-introduced setters macros.
6185 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6186 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6187 (set_fontset_default, set_fontset_fallback): Rename from their
6188 upper-case counterparts, and make them functions rather than macros.
6189 This is more consistent with the other recently-introduced setters.
6190 These don't need to be inline, since they're local.
6192 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6194 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6195 the loop (Bug#12247).
6197 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6199 * lisp.h (vcopy): Use memcpy rather than our own loop.
6200 This fixes a performance regression introduced by the recent
6201 addition of vcopy. This means 'vcopy' will need to be modified
6202 for a copying collector, but that's OK. Also, tighten the
6203 checking in the assertion.
6205 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6207 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6208 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6209 non-base glyph for the width of the base character, according to
6210 what x_draw_composite_glyph_string_foreground expects.
6211 Generate WADJUST value according to composition_gstring_width's
6212 expectations, to produce correct width of the composed character.
6213 Reverse the sign of the DU offset produced by ScriptPlace.
6215 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6217 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6219 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6221 Avoid direct writes to contents member of struct Lisp_Vector.
6222 * lisp.h (vcopy): New function to copy data into vector.
6223 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6224 * fns.c (Ffillarray): Use ASET.
6225 * keyboard.c (timer_check_2): Use AREF and ASET.
6226 (append_tool_bar_item, Frecent_keys): Use vcopy.
6227 * lread.c (read_vector): Use ASET.
6228 * msdos.c (Frecent_doskeys): Use vcopy.
6229 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6230 (Finternal_merge_in_global_face): Use ASET and vcopy.
6231 * xfont.c (xfont_list_pattern): Likewise.
6233 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6235 * window.c (Fwindow_point): For the selected window always return
6236 the position of its buffer's point.
6237 (Fset_window_point): For the selected window always go in its
6238 buffer to the specified position.
6240 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6242 Setter macros for fontsets.
6243 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6244 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6245 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6248 2012-08-20 Glenn Morris <rgm@gnu.org>
6250 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6251 Don't assume that `ln -f' works.
6253 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6255 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6256 and later about non-assignments with no effect. See discussion at
6257 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6260 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6262 Inline setter functions for Lisp_Objects slots of struct specbinding.
6263 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6266 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6268 * window.c (select_window): Always make selected window's buffer
6271 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6273 Use AREF and ASET for docstrings of category tables.
6274 * category.h (CATEGORY_DOCSTRING): Use AREF.
6275 (SET_CATEGORY_DOCSTRING): Use ASET.
6276 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6278 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6280 Inline setter functions for hash table members.
6281 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6282 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6283 (set_hash_key_and_value, set_hash_index, set_hash_next)
6284 (set_hash_hash): New functions.
6285 * charset.c, fns.c: Adjust users.
6287 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6289 Inline getter and setter functions for per-buffer values.
6290 * buffer.h (per_buffer_default, set_per_buffer_default)
6291 (per_buffer_value, set_per_buffer_value): New functions.
6292 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6293 * buffer.c, data.c: Adjust users.
6295 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6297 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6299 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6301 Rely on <config.h> + <unistd.h> to declare 'environ',
6302 as gnulib does this if the system doesn't.
6303 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6304 Remove declaration. MS-Windows declares it on stdlib.h which is
6305 included by conf_post.h.
6306 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6307 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6308 * vm-limit.c: Include <unistd.h>, for 'environ'.
6310 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6311 (start_of_data): Remove decl; mem-limits.h provides it.
6313 * xdisp.c (handle_invisible_prop): Make it a bit faster
6314 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6316 2012-08-19 Chong Yidong <cyd@gnu.org>
6318 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6321 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6323 * .gdbinit: Use call instead of set when calling a function in the
6326 * data.c (set_internal): Don't use set_blv_found.
6327 (Fkill_local_variable): Likewise.
6329 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6331 * nsfont.m (ns_ascii_average_width): Ensure the string
6332 ascii_printable is initialized with a null-terminated character
6333 array. Otherwise, it can contain undesired extra characters.
6335 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6337 port new setting code to Sun C 5.8 2005/10/13
6338 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6339 Return void, not Lisp_Object. Otherwise, the compiler
6340 complains about (A?B:C) where B is void and C is Lisp_Object
6341 when compiling CHAR_TABLE_SET, due to the recent change to
6342 the API of sub_char_table_set_contents.
6344 2012-08-18 Chong Yidong <cyd@gnu.org>
6346 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6347 for the string case (Bug#3874).
6349 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6351 * buffer.h (BSET): Remove (Bug#12215).
6352 Replace all uses with calls to new setter functions.

7283 Fix macroexp crash on Windows with debugging (Bug#12118).
7284 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7285 checking subscripts; problem introduced with the recent
7286 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7287 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7288 since it's used in non-static inline functions now.
7290 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

7340 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7342 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7343 This how ASET and AREF are supposed to work, and makes
7344 it easier to think about future improvements. See
7345 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7346 * charset.h (set_charset_attr): New function.

7728 (w32_kbd_patch_key, key_event): Use the codepage returned by
7729 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
7730 (key_event): use uChar.UnicodeChar only if

7761 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7762 enumeration constants, as PURE and HEAP are too general, and clash
7763 with other headers and sources, such as gmalloc.c and the
7764 MS-Windows system headers. All users changed.
7766 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7768 Revert last save_excursion_save and save_excursion_restore changes.
7769 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7782 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7783 arms of an 'if', not using conditional expressions; otherwise GDB
7784 complains about the types in the unevaluated arm when the argument
7785 is an integer literal.
7786 (xgetint): Simplify expression.
7787 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7788 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7789 Zaretskii in <http://bugs.gnu.org/12036#13>.
7790 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7791 needed now that we have gdb_make_enums_visible.
7792 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7793 (enum enum_USE_LSB_TAG):
7794 New enum types, packaging up enums that need to be exported to GDB.

7818 * lisp.h (struct Lisp_Excursion): New data type.
7819 (PVEC_EXCURSION): New pseudovector type.
7820 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7821 to deal with it. Adjust comments.

7836 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7837 emacs.c, as this is a more-suitable home. Had this been done earlier
7838 the fix for 12036 would have avoided some of the problems noted in
7839 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7840 would have been more obvious.
7841 * emacs.c: Do not include <verify.h>; no longer needed.
7842 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7843 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7844 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

7848 (DATA_SEG_BITS): Use it.
7849 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7850 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7851 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7852 not be usable in #if. This simplifies things.
7854 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7856 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7861 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7862 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7863 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7864 Adjust to changes in lisp.h and emacs.c, by using
7865 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7866 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7867 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7868 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7869 instead of gdb_valbits.
7870 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7871 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7872 instead of gdb_array_mark_flag.
7873 (xboolvector): Get size from $->size, not $->header.size.
7874 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7875 (xreload, hook-run, hookpost-run): Remove.
7876 * emacs.c: Include <verify.h>.
7877 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7878 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7880 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7881 (gdb_USE_LSB_TAG): New enum constants.
7882 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7883 Also define these as enum constants, so they're visible to GDB.
7884 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7885 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7886 as constants, so they're visible to GDB.
7887 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)

7889 Now enum constants, not macros, so they're visible to GDB.
7890 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7891 more convenient now. All uses changed.
7892 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7893 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7895 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7902 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7903 add argument, tune behavior, and adjust all callers.
7905 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7907 Use typedef for EMACS_INT, EMACS_UINT.
7908 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7909 than macros. This simplifies debugging in the usual case, since
7910 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7911 and it allows expressions involving EMACS_INT casts.
7912 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7914 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7924 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7926 Adjust buffer text indirection counters at the end of Fkill_buffer.
7927 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7928 buffer is definitely dead. This should really fix an issue reported
7929 by Christoph Scholtes again. (Bug#12007).
7930 (init_buffer_once): Initialize indirection counters of
7931 buffer_defaults and buffer_local_symbols (for sanity and safety).
7933 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7935 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7936 and continuation glyphs on tooltip frames, leave them at zero.

7939 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7941 Simplify copy_overlay.
7942 * buffer.c (copy_overlay): Simplify. Use build_marker.

7962 (build_overlay): Add prototype.
7964 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7966 Swap buffer text indirection counters in Fbuffer_swap_text.
7967 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7968 This avoids crash reported by Christoph Scholtes at
7969 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7971 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7973 * nsmenu.m (Popdown_data): New struct.
7974 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7976 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7977 (initWithContentRect): Make imgView and contentView non-static
7978 and autorelease them. Also autorelease img and matrix (Bug#12005).
7979 (dealloc): Remove (Bug#12005).
7981 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7983 Adjust consing_since_gc when objects are explicitly freed.

7996 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7998 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7999 as it's limited by the amount of memory, not by INT_MAX.
8001 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8003 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8004 in special-event-map. See the discussion at

8063 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8064 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8065 Adjust users accordingly.
8066 * font.h (font_open_by_name): Adjust prototype.

8085 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8086 'for_each_per_buffer_object_at'.
8087 All uses changed. It's better to use upper-case for macros that

8727 * s/aix4-2.h (unix): Remove; no longer needed.
8729 EMACS_TIME simplification (Bug#11875).
8730 This replaces macros (which typically do not work in GDB)

8732 The functional style also makes code easier to read and maintain.
8733 * systime.h: Include <sys/time.h> on all hosts, not just if
8734 WINDOWSNT, since 'struct timeval' is needed in general.

8749 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8750 (add_emacs_time, sub_emacs_time): New functions.
8751 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

8771 Prefer memcmp to strncmp when either will do.
8772 * nsterm.m: Include <ftoastr.h>.
8774 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8775 Prefer snprintf to strncpy.
8776 * nsterm.m (ns_term_init):
8777 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8778 * nsterm.m (ns_term_init):
8779 Avoid the need for strncpy, by using build_string or
8780 make_unibyte_string directly. Use dtoastr, not snprintf.
8781 * process.c (Fmake_network_process): Diagnose service names that
8782 are too long, rather than silently truncating them or creating
8783 non-null-terminated names.
8784 (Fnetwork_interface_info): Likewise, for interface names.
8785 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8786 Prefer sprintf to strncat.

8799 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8800 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8801 where argument type is known to be a Lisp_Cons.

8813 Optimize pure C strings initialization.
8814 * lisp.h (make_pure_string): Fix prototype.
8815 (build_pure_c_string): New function, defined as static inline. This
8816 provides a better opportunity to optimize away calls to strlen when
8817 the function is called with compile-time constant argument.
8818 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8819 argument, adjust users accordingly. Use build_pure_c_string where

8822 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8823 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

8853 We include usg5-4-common.h, which defines them both.
8855 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8856 O_RDONLY already includes it).
8858 Stop ns builds setting the EMACSLOADPATH environment variable.
8859 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8860 Now it does not set EMACSLOADPATH, just returns the load-path string.
8861 * nsterm.h: Update accordingly.
8862 * lread.c [HAVE_NS]: Include nsterm.h.
8863 (init_lread) [HAVE_NS]: Use ns_load_path.

8866 2012-07-09 Glenn Morris <rgm@gnu.org>
8868 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8869 since the included bsd-common.h does so.
8871 Stop ns builds setting the EMACSPATH environment variable.
8872 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8873 (ns_init_paths): Do not set EMACSPATH.
8874 * nsterm.h (ns_exec_path): Add it.
8875 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8878 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8880 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8882 * process.c (wait_reading_process_output): 'waitchannels' was unset
8883 when read_kbd || !NILP (wait_for_cell); fix this.
8885 Add GCC-style 'const' attribute to functions that can use it.
8886 * character.h (char_resolve_modifier_mask):
8887 * keyboard.h (make_ctrl_char):
8888 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8899 Minor improvements to make_formatted_string.
8900 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t

8902 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8904 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>

8933 Move marker debugging code under MARKER_DEBUG.
8934 * marker.c (MARKER_DEBUG): Move marker debugging code under
8935 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8936 for bootstrap with --enable-checking (~3x slowdown reported
8937 by Juanma Barranquero <lekktu@gmail.com>).
8938 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8940 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8942 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.

8947 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8948 has no font, use the frame's font. (Bug#11813)
8949 (display_line): Add commentary about displaying truncation glyphs
8951 (produce_special_glyphs): Move here from term.c.
8953 * term.c (produce_special_glyphs): Move to xdisp.c.
8955 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8958 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8960 * xdisp.c (display_line): Avoid warning about implicit declaration
8963 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8965 * lisp.h: Remove empty conditional.
8967 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8969 * lread.c (load_path_check): Now static.
8971 Fix some minor --with-ns problems found by static checking.

8975 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8976 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8977 Remove unused local.

8990 * lread.c (load_path_check): New function, split from init_lread.
8991 (init_lread): Reorganize. Motivation:
8992 If EMACSLOADPATH is set, check/warn about that rather than the
8993 defaults, which we are not going to use. Hence we can remove
8994 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8995 Don't warn if site-lisp directories are missing.
8996 If not installed, start from a blank load-path, since
8997 PATH_LOADSEARCH refers to the eventual installation directories.

9008 GUI frame without a fringe to display continuation or truncation
9010 (insert_left_trunc_glyphs): Support GUI frames: make sure
9011 truncation glyphs overwrite enough glyphs from the current line to
9012 have sufficient space in pixels.
9013 (display_line): Support truncation and continuation glyphs on GUI
9014 frames. If some spare pixels are left on the line after inserting
9015 the truncation glyphs, fill that space with a stretch glyph of a
9016 suitably computed width.
9018 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9019 produce_glyphs, to support GUI sessions.
9021 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9023 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).

9027 Do not require float-time's arg to fit in time_t (Bug#11825).
9028 This works better on hosts where time_t is unsigned, and where
9029 float-time is applied to the (negative) difference between two times.
9030 * editfns.c (decode_time_components): Last arg is now double *,
9031 not int *, and means to store all the result as a double, without
9032 worrying about whether the seconds part fits in time_t.
9033 All callers changed.
9034 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9035 All callers changed.
9036 (Ffloat_time): Do not fail merely because the specified time falls
9037 outside of time_t range.
9039 2012-07-07 Glenn Morris <rgm@gnu.org>
9041 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9056 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9057 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.

9063 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9065 * xfns.c (Fx_change_window_property): Doc fix.
9066 * w32fns.c (Fx_change_window_property): Doc fix.
9068 * w32fns.c (Fx_window_property): Accept the same arguments as the
9069 X Windows version. Doc fix.
9070 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9072 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9073 Eli Zaretskii <eliz@gnu.org>
9075 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9076 Windows-specific code from nt/config.nt moved here.
9077 Obsolete settings removed.
9079 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9081 * process.c: Avoid unnecessary calls to gettime.
9082 (wait_reading_process_output): Don't get the time of day
9083 when gobbling data immediately and not waiting, as there's no need
9084 for it in that case. This removes a FIXME.
9086 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9088 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9089 is defined (Bug#11768).

9093 Fix marker debugging code.
9094 * marker.c (byte_char_debug_check): Do not perform the check
9095 if buffer is not multibyte.
9096 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9097 Call byte_char_debug_check with correct arguments.
9099 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9101 Compile marker debugging code only if ENABLE_CHECKING is defined.
9102 * marker.c (byte_char_debug_check, count_markers):
9103 Use only if ENABLE_CHECKING is defined.
9104 (byte_debug_flag): Remove.
9105 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9106 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9108 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9110 Avoid code repetition in marker-related functions.
9111 * marker.c (attach_marker): New function.

9114 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9115 Consistently rename charno to charpos.
9116 (marker_position): Add eassert.
9117 (marker_byte_position): Convert to eassert.

9129 * lisp.h (build_marker): New prototype.
9130 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9131 * composite.c (autocmp_chars): Likewise.
9132 * editfns.c (buildmark): Remove.
9133 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9134 (save_restriction_save): Use build_marker.
9135 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9136 * window.c (save_window_save): Likewise.
9138 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9140 Do not use Fdelete_overlay in delete_all_overlays
9141 to avoid redundant calls to unchain_overlay.
9142 * buffer.c (drop_overlay): New function.
9143 (delete_all_overlays, Fdelete_overlay): Use it.
9144 * minibuf.c (get_minibuffer): Fix comment.
9146 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9148 Port to OpenBSD 5.1 amd64.
9149 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9150 This is needed for OpenBSD, and should be harmless on all BSD systems.
9151 Also, include <sys/sysctl.h>, as it should be available on all
9152 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9153 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9154 use p_pid member, not kp_proc.pid.
9156 2012-07-06 Glenn Morris <rgm@gnu.org>
9158 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9160 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9162 More xmalloc and related cleanup.

9170 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9171 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9173 Omit needless casts involving void * pointers and allocation.
9174 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9175 as the former is more robust if P's type is changed.
9176 Prefer xzalloc to xmalloc + memset 0.
9177 Simplify malloc-or-realloc to realloc.
9178 Don't worry about xmalloc returning a null pointer.
9179 Prefer xstrdup to xmalloc + strcpy.
9180 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9182 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9183 alloca of a constant.
9185 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9187 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9188 hscroll is larger than the line width. Fixes long and futile
9189 looping inside extend_face_to_end_of_line (on a TTY) producing
9190 glyphs that are not needed and thrown away.
9192 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9194 * marker.c (set_marker_restricted_both): Simplify by using
9197 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9199 * editfns.c (region_limit): Simplify by using clip_to_bounds.

9208 followed by gtk_box_set_homogeneous (Bug#11768).
9209 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9210 (update_theme_scrollbar_width, xg_create_scroll_bar):
9211 Use gtk_scrollbar_new (Bug#11768).
9212 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9213 (is_box_type): New function (Bug#11768).
9214 (xg_tool_item_stale_p): Call is_box_type.
9215 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9216 with default display (Bug#11768).

9220 * xdisp.c (window_hscroll_limited): New function.
9221 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9222 coordinates when window's hscroll is set to insanely large
9225 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9227 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9286 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9288 * fileio.c (time_error_value): Check the right error number.
9289 Problem reported by Troels Nielsen in
9290 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

9294 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9295 This should be fixed in a better way; see Eli Zaretskii in
9296 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9297 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9299 * fileio.c (time_error_value): Rename from special_mtime.
9300 The old name's problems were noted by Eli Zaretskii in
9301 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9303 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9304 This variable's comment says Emacs needs at least one GDB-visible
9305 symbol of type enum pvec_type, to work around GDB problems.
9306 The symbol's value doesn't matter.
9308 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9309 that causes compilation to fail on pre-C99 compilers.
9311 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9313 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9326 (PSEUDOVECTOR_SIZE_BITS): New constant.
9327 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9328 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9329 change in pvec_type.

9336 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9337 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9338 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9339 abusing vector->header.next.nbytes.
9340 (live_vector_p): Use PVEC_TYPE.
9341 (mark_object): Adapt code to extract pvectype. Use switch.
9343 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9345 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9346 Tighten new eassert a bit.
9348 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9350 Fix compilation with --enable-gcc-warnings and -O1
9352 * doprnt.c (doprnt): Change type of tem to int, initialize
9353 to avoid compiler warning. Add eassert.
9354 * search.c (simple_search): Initialize match_byte to avoid
9355 compiler warning. Add eassert.
9357 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9359 Avoid weird behavior with large horizontal scrolls.
9360 Without this change, for example, large hscroll values would
9361 mess up Emacs's display on Fedora 15 x86, presumably due to
9362 overflows in int calculations in the display code.
9363 Also, if buffers had long lines, Emacs would freeze.
9364 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9365 (set_window_hscroll): New function, containing the old guts of
9366 Fset_window_hscroll. Return the clipped value.
9367 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9368 This avoids the need to check against PTRDIFF_MAX.
9370 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9372 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

9376 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9378 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9379 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9380 since GCC 4.4.6 issues a bogus warning for them.
9382 Fix bugs in file timestamp newness comparisons.
9383 * fileio.c (Ffile_newer_than_file_p):
9384 * lread.c (Fload): Use full timestamp resolution of files,
9385 not just the 1-second resolution, so that files that are only
9386 slightly newer still count as newer.
9387 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9388 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9390 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9392 * fileio.c: Improve handling of file time marker. (Bug#11852)
9393 (special_mtime): New function.
9394 (Finsert_file_contents, Fverify_visited_file_modtime):
9395 Use it to set special mtime values consistently.
9397 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9399 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9400 marker for non-existing file. (Bug#11852)
9402 2012-07-03 Glenn Morris <rgm@gnu.org>
9404 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9405 and did not make it into globals.h).
9407 2012-07-03 Tom Tromey <tromey@redhat.com>

9445 2012-07-03 Glenn Morris <rgm@gnu.org>
9447 * lisp.h (Frandom): Make it visible to C.
9448 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9449 buffer for invisible buffers. (Bug#1229)

9453 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9454 values which aren't power of 2.
9455 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9456 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9459 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9461 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

9467 * alloc.c (allocate_vector_block): Remove redundant
9468 calls to mallopt if DOUG_LEA_MALLOC is defined.
9469 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9470 avoid calls to mallopt if zero_vector is returned.
9472 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9474 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9475 is enabled, avoid dereferencing NULL current_sblock if
9478 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9480 Cleanup basic buffer management.
9481 * buffer.h (struct buffer): Change layout to use generic vector
9482 marking code. Fix some comments. Change type of 'clip_changed'
9483 to bitfield. Remove unused #ifndef old.
9484 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.

9488 (Fbuffer_local_variables): Use it.
9489 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9490 * alloc.c (allocate_buffer): Adjust to match new layout of
9491 struct buffer. Fix comment.
9492 (mark_overlay): New function.
9493 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9494 Lisp area of struct buffer.
9495 (mark_object): Use it. Adjust marking of misc objects
9496 and related comments.
9498 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9500 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9501 wrapper that is not needed because the wrapped code is a no-op (zero
9502 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9503 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9505 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9507 * alloc.c (mark_buffer): Simplify. Remove prototype.
9508 (mark_object): Add comment. Reorganize marking of vector-like
9509 objects. Use CHECK_LIVE for all vector-like objects except buffers
9510 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9511 Avoid redundant calls to mark_vectorlike for bool vectors.
9513 2012-06-30 Glenn Morris <rgm@gnu.org>
9515 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9517 * epaths.in (PATH_SITELOADSEARCH): New.
9518 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9519 This is rather than relying on --enable-locallisppath elements
9520 having "site-lisp" in their names. (Bug#10208#25, 11658)
9522 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9524 * w32proc.c (sys_select): Accept and ignore one more argument.
9526 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9528 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9529 (pselect) [!MS_DOS]: Redirect to sys_select.
9531 * sysdep.c: Don't include dos.h and dosfns.h.
9533 * process.c (sys_select):
9534 * msdos.c (sys_select): Accept one more argument and ignore it.
9536 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9537 adapt data types and code to that.
9540 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9541 which clashes with the gnulib function of the same name.
9543 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9545 * font.c (font_style_to_value, font_style_symbolic)
9546 (font_prop_validate_style): Add type checks for values in
9549 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9551 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9554 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9556 * xdisp.c (try_window_id): Undo last change.
9558 * w32.c (getwd): Adjust commentary about startup_dir.
9559 (init_environment): Always call sys_access, even in non-MSVC
9560 builds. Don't chdir to the directory of the Emacs executable.
9561 This undoes code from 1997 which was justified by the need to
9562 "avoid conflicts when removing and renaming directories". But its
9563 downside was that every relative file name was being interpreted
9564 relative to the directory of the Emacs executable, which can never
9565 be TRT. In particular, it broke sys_access when called with
9566 relative file names.
9567 (sys_access): Map GetLastError to errno.
9569 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9571 * window.h (struct window): Change type of 'fringes_outside_margins'
9572 to bitfield. Fix comment. Adjust users accordingly.
9573 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9575 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9578 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9580 * gnutls.c (emacs_gnutls_handshake):
9581 Add QUIT to make the loop interruptible.
9583 2012-06-29 Glenn Morris <rgm@gnu.org>
9585 * charset.c (init_charset): Make lack of etc/charsets fatal.
9587 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9589 * editfns.c (region_limit): Fix type mismatch.
9591 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9593 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9594 undefined. Convert from xassert to eassert.
9595 * nsmenu.m: Convert from xassert to eassert.
9596 * nsterm.m: Likewise.
9598 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9600 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9602 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9604 Avoid integer overflow on scroll-left and scroll-right.
9605 * window.c (HSCROLL_MAX): New macro.
9606 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9607 overflow when requested scroll falls outside ptrdiff_t range.
9609 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9611 * window.h (struct window): Change type of 'hscroll',
9612 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9613 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9614 Adjust users accordingly.
9615 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9616 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9617 from EMACS_INT to ptrdiff_t.
9618 (make_window): Omit redundant initialization.
9620 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9622 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9624 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9626 * window.h (struct window): Change type of 'use_time' and
9627 'sequence_number' from Lisp_Object to int.

9636 enabled with --enable-checking=[all,glyphs] configure option.
9637 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9638 adjust comments accordingly.

9687 * alloc.c (allocate_string_data): Remove dead code.
9688 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
9689 avoid GCC warning about unused macro.
9691 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9693 * alloc.c (allocate_string): Omit intervals initialization.
9694 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9695 as in make_pure_string and make_pure_c_string.
9697 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9699 * alloc.c (allocate_string): Fix last change.
9701 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9714 2012-06-26 John Wiegley <johnw@newartisans.com>
9716 * unexmacosx.c (copy_data_segment): Add two section names used
9717 on Mac OS X Lion: __mod_init_func and __mod_term_func.
9719 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
9720 when building with Clang.
9722 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

9726 2012-06-26 Eli Zaretskii <eliz@gnu.org>
9728 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
9729 _stricmp and _strnicmp.
9730 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
9732 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9734 * alloc.c (allocate_window): Zero out non-Lisp part of newly
9736 (allocate_process): Likewise for new process.

9747 * term.c (delete_tty): Remove redundant call to memset.
9749 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9751 * alloc.c: Remove build_string.
9752 * lisp.h: Define build_string as static inline. This provides
9753 a better opportunity to optimize away calls to strlen when the
9754 function is called with compile-time constant argument.
9755 * image.c (imagemagick_error): Convert to build_string.
9756 * w32proc.c (sys_spawnve): Likewise.
9757 * xterm.c (x_term_init): Likewise.
9759 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9761 Use sprintf return value instead of invoking strlen on result.
9762 In the old days this wasn't portable, since some sprintf
9763 implementations returned char *. But they died out years ago and
9764 Emacs already assumes sprintf returns int.
9765 Similarly for float_to_string.
9766 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9767 * ccl.c (ccl_driver):
9768 * character.c (string_escape_byte8):

9771 * print.c (print_object):
9772 * xdisp.c (message_dolog):
9773 * xfns.c (syms_of_xfns):
9774 Use sprintf or float_to_string result to avoid need to call strlen.
9775 * data.c (Fnumber_to_string):
9776 Use make_unibyte_string, since the string must be ASCII.
9777 * lisp.h, print.c (float_to_string): Now returns int length.
9778 * term.c (produce_glyphless_glyph):
9779 Use sprintf result rather than recomputing it.
9781 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9782 * Makefile.in (ALL_CFLAGS):
9783 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9784 * gmalloc.c, regex.c: Include <config.h> unconditionally.
9786 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9788 * dispextern.h (xstrcasecmp): Define to library function
9789 strcasecmp if available.
9790 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
9792 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
9794 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):
9795 Avoid comma operator.

9805 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9807 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9808 sprintf already null-terminates its output.
9810 * xfns.c (x_window): Remove redundant cast.
9812 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9814 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9815 `const char *' to `char *' to avoid compiler warning.
9817 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9819 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9820 instead of truncating it to 63 (admittedly a generous limit).
9822 * process.c: Fix spelling and caps in comments.
9824 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9826 * emacs.c (setpgrp): Remove definition, unused.

9836 (SYSTIME_H): Add nt/inc/sys/time.h.
9838 * systime.h [WINDOWSNT]: Include sys/time.h.
9840 * s/ms-w32.h (struct timespec): Definition moved from
9841 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
9843 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

9870 Use _Noreturn rather than NO_RETURN.
9871 No need for separate decl merely because of _Noreturn.
9872 * sound.c (sound_warning, parse_sound):
9873 Remove unnecessary forward decls.
9875 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9877 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9878 * lisp.h (WAIT_READING_MAX): New macro.
9879 * dispnew.c (Fsleep_for, sit_for):
9880 * keyboard.c (kbd_buffer_get_event):
9881 * process.c (Faccept_process_output):
9882 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9883 This improves on the previous patch, which introduced a bug
9884 when time_t is unsigned and as wide as intmax_t.
9885 See <http://bugs.gnu.org/9000#51>.
9887 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9889 * dispnew.c (sit_for, Fsleep_for):
9890 * keyboard.c (kbd_buffer_get_event):

9892 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
9894 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
9896 * makefile.w32-in: Update dependencies.
9898 * w32.c (ltime): Add return type and declare static.
9899 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
9901 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9903 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9904 Privately reported by Herbert J. Skuhra.
9905 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9907 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9908 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9910 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9912 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9913 last argument of make_unibyte_string.
9915 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9916 language ID in the event parameters.
9918 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9919 event.code, not the obscure "character set ID".
9921 2012-06-23 Chong Yidong <cyd@gnu.org>
9923 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9925 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9927 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
9928 * w32.c (fdutimens): New function.
9930 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
9932 * s/ms-w32.h (pselect): Redirect to sys_select.
9934 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.

9938 use_relocatable_buffers.
9940 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9942 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9943 Privately reported by Herbert J. Skuhra.

9950 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9952 Support higher-resolution time stamps (Bug#9000).
9953 The time stamps are only nanosecond-resolution at the C level,
9954 since that's the best that any real-world system supports now.
9955 But they are picosecond-resolution at the Lisp level, as that's
9956 easy, and leaves room for future OS improvements.
9958 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9961 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9962 Don't get current time unless it's needed.
9964 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9965 now provides it if it's absent.
9966 (start_atimer): Port to higher-res time stamps.
9967 Check for time stamp overflow. Don't get current time more
9968 often than is needed.
9970 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9971 Include systime.h, not time.h.
9972 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9974 * dired.c: Include stat-time.h.
9975 (Ffile-attributes): File times now have higher resolution.
9977 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9978 (struct image): Timestamp now has higher resolution.
9980 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9981 has at least microseconds now. All uses removed.
9982 (update_frame, update_single_window, update_window, update_frame_1)
9983 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9984 (duration_to_sec_usec): Remove; no longer needed.
9986 * editfns.c (time_overflow): Now extern.
9987 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9988 (float-time, Fformat_time_string, Fcurrent_time_string)

9994 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9995 Report an error if the time is invalid, rather than having the caller
9998 * fileio.c: Include <stat-time.h>
9999 (Fcopy_file): Copy higher-resolution time stamps.
10000 Prefer to set the time stamp via a file descriptor if that works.

10017 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10018 Port to higher-resolution time stamps. Do not assume time_t is signed.
10019 (decode_timer): New function. Timers are now vectors of length 9,
10020 not 8, to accommodate the picosecond component.
10021 (timer_check_2): Use it.
10023 * nsterm.m (select_timeout, timeval_subtract): Remove.
10024 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10025 as they're a bit more accurate and handle overflow better.
10026 (ns_select): Change prototype to be compatible with pselect.
10027 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10028 * nsterm.h (ns_select): Adjust prototype.
10030 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes

10047 (Faccept_process_output, wait_reading_process_output):
10048 Check for time stamp overflow. Do not assume time_t is signed.
10049 (select_wrapper): Remove; we now use pselect.
10050 (Fprocess_attributes): Now generates ns-resolution time stamps.
10052 * sysdep.c: Include utimens.h. Don't include utime.h
10053 or worry about struct utimbuf; gnulib does that for us now.
10054 (gettimeofday): Remove; gnulib provides a substitute.
10055 (make_timeval): New function.
10056 (set_file_times): Now sets ns-resolution time stamps.
10057 New arg FD; all uses changed.

10060 Now returns ns-resolution time stamp. All uses changed.
10061 Check for time stamp overflow.
10063 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10064 provides a substitute now.
10066 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10067 since it guarantees struct timespec.
10068 (EMACS_TIME): Now struct timespec, so that we can support
10069 ns-resolution time stamps.
10070 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10071 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10072 (EMACS_USECS): Remove.
10073 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10074 so multiply the arg by 1000 before storing it.
10075 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10077 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10084 (make_timeval, make_lisp_time, decode_time_components): New decls.
10085 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10086 that it mishandled time_t overflow. You can't compare by subtracting!
10087 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10088 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10090 * term.c: Include <sys/time.h>.

10095 in the undo buffer.
10096 (Fprimitive_undo): Use them when restoring time stamps.
10098 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10099 (w32_get_internal_run_time):
10100 Port to higher-resolution Emacs time stamps.
10101 (ltime): Now accepts single 64-bit integer, as that's more convenient
10104 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10106 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10107 for compatibility with pselect. Support ns-resolution time stamps.
10109 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10111 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10112 Check for time stamp overflow, and support ns-resolution time stamps.

10115 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10116 (timeval_subtract): Remove; no longer needed.
10117 (XTflash, XTring_bell, x_wait_for_event):
10118 Port to ns-resolution time stamps. Don't assume time_t is signed.

10124 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10126 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10127 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10128 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10129 staticidx goes up to 1597 out of 1600 = 0x640.)
10131 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10133 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10134 Otherwise, the umask might be mistakenly 0 while handling input signals.
10136 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

10155 (unwind_format_mode_line): Restore them.
10156 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10158 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

10167 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10168 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10169 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10170 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10177 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10179 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10180 gets killed during executing of this function (Bug#11665).
10181 Try to always return Qt when the buffer has been actually killed.
10182 (Vkill_buffer_query_functions): In doc-string say that functions
10183 run by this hook should not change the current buffer.
10185 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10187 Fix recently-introduced process.c problems found by static checking.

10207 * lisp.h (eassert): Assume C89 or later.
10208 This removes the need for CHECK.
10209 (CHECK): Remove. Its comments about always evaluating its
10210 argument were confusing, as 'eassert' typically does not evaluate
10213 * coding.c (produce_chars): Use ptrdiff_t, not int.
10215 * xterm.c (x_draw_underwave): Check for integer overflow.
10216 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10402 as the union type is for debugging, not for production.
10403 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10404 Use an inline function on all platforms when using the union type,
10405 since this is simpler and 'static inline' can be used portably
10407 (LISP_INITIALLY_ZERO): New macro.

10547 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10549 * doprnt.c (doprnt): Truncate multibyte char correctly.
10550 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10551 would mishandle a string argument "Xc" if X was a multibyte
10552 character of length 2: it would truncate after X's first byte
10553 rather than including all of X.
10555 2012-06-06 Chong Yidong <cyd@gnu.org>
10557 * buffer.c (word_wrap): Doc fix.

10604 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10606 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10607 Convert pctcpu and pctmem to Lisp float properly.
10608 Let the compiler fold better, as 100.0/0x8000 is exact.
10610 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10612 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10622 bitfields where appropriate, remove unused fields.
10623 * window.h (struct window): Remove unused 'last_mark_x' and
10624 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10625 change its type from Lisp_Object to bitfield.
10626 Change type of 'force_start', 'optional_new_start',
10627 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10628 fields from Lisp_Object to bitfield. Adjust users accordingly.
10630 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10632 Pacify gcc -Wdouble-precision when using Xaw.
10633 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10634 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10635 Use 'float' consistently, rather than 'float' in most places
10636 and 'double' in a couple of places.
10638 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10640 * xdisp.c (handle_stop): Detect whether we have overlay strings
10641 loaded by testing it->current.overlay_string_index to be
10642 non-negative, instead of checking whether n_overlay_strings is
10643 positive. (Bug#11587)
10645 2012-05-31 Chong Yidong <cyd@gnu.org>
10647 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10653 * search.c (search_buffer): Remove calls to
10654 r_alloc_inhibit_buffer_relocation, as it is now called by
10655 maybe_unify_char, which was the cause of relocation of buffer text
10658 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10660 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10661 for the duration of call to load_charset, to avoid problems with
10662 callers of maybe_unify_char that access buffer text through C
10665 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10666 decrement the inhibition flag, instead of just setting or
10669 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10671 Remove obsolete '#define static' cruft.
10672 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10673 This #undef was "temporary" in 2000; it is no longer needed
10674 now that '#define static' has gone away.
10675 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10676 (gray_bitmap_bits): Remove; no longer needed.
10677 All uses replaced with definiens.

10685 Define only on platforms that need it.
10686 * emacs.c: Include <sys/gmon.h> when profiling.
10687 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10688 (__executable_start): Remove decl, since lisp.h does it now.
10689 (safe_bcopy): Remove decl; no longer has that name.
10690 (main): Coalesce #if into single bit of code, for simplicity.
10691 Cast pointers to uintptr_t, since standard libraries want integers
10693 * lisp.h (__executable_start): New decl.
10695 2012-05-31 Glenn Morris <rgm@gnu.org>
10697 * image.c (Fimagemagick_types): Doc fix.

10720 Do not create empty overlays with the evaporate property (Bug#9642).
10721 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10722 Bug#9642, but explicitly check that the buffer the overlay would
10723 be moved to is live and rearrange lines to make sure that errors
10724 will not put the overlay in an inconsistent state.
10725 (Fdelete_overlay): Cosmetics.
10727 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10729 * w32term.c (my_bring_window_to_top): New function.
10730 (x_raise_frame): Use handle returned by DeferWindowPos, which
10731 could be different from the original one.

10745 to not catch an out-of-range value.
10747 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10749 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

10763 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10764 Only r_alloc_inhibit_buffer_relocation needed to be added;
10765 the others were already declared.
10767 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10768 before checking whether it's out of range. Put the check inside
10770 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10772 2012-05-27 Ken Brown <kbrown@cornell.edu>

10784 they are now on lisp.h.
10786 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10788 * search.c (search_buffer): Use it to inhibit relocation of buffer
10789 text while re_search_2 is doing its job, because re_search_2 is
10790 passed C pointers to buffer text. (Bug#11519)
10792 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10793 Update value to 24.
10795 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10796 state after an additional call to move_it_in_display_line_to, keep
10797 the values of it->max_ascent and it->max_descent found for the
10799 (pos_visible_p): Revert the comparison against bottom_y to what it
10800 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10803 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10805 Fix coding-related core dumps with gcc -ftrapv.
10806 The code was computing A - B, where A and B are pointers, and B is
10807 random garbage. This can lead to core dumps on platforms that
10808 have special pointer registers, and it also leads to core dumps on
10809 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10810 A - B only when B is initialized properly.
10811 * coding.c (coding_set_source, coding_set_destination): Return void.
10812 (coding_change_source, coding_change_destinations): New functions,
10813 with the old behaviors of coding_set_source and coding_set_destination.

10824 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10826 * w32console.c: Include window.h.
10827 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10829 (initialize_w32_display): Initialize mouse-highlight data.
10831 * w32inevt.c: Include termchar.h and window.h.
10832 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10833 moves, call note_mouse_highlight. If help_echo changed, call
10834 gen_help_event to produce help-echo message in the echo area.
10835 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10838 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10840 * lread.c (read1): Simplify slightly to avoid an overflow warning
10841 with GCC 4.7.0 on x86-64.
10843 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10845 * bidi.c (bidi_mirror_char): Revert last change: an int is
10846 definitely wide enough here.

10858 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10860 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10861 (allocate_pseudovector):
10862 Use int, not EMACS_INT, where int is wide enough.
10863 (inhibit_garbage_collection, Fgarbage_collect):
10864 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10865 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10866 int might not be wide enough.

10882 (Foverlay_recenter, last_overlay_modification_hooks_used)
10883 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10884 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10885 (validate_region): Omit unnecessary test for b <= e,
10886 since that's guaranteed by the previous test.
10887 (adjust_overlays_for_delete): Avoid pos + length overflow.
10888 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10889 (report_overlay_modification):
10890 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10891 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10892 Omit pointer cast, which isn't needed anyway, and doesn't work
10893 after the EMACS_INT -> ptrdiff_t change.
10894 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10895 * buffer.h: Adjust decls to match defn changes elsewhere.
10896 (struct buffer_text, struct buffer):
10897 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10898 Use EMACS_INT, not int, where int might not be wide enough.
10899 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10900 not int, to avoid needless 32-bit limit on 64-bit hosts.
10901 (exec_byte_code): Use tighter memory-full test, one that checks
10902 for alloca overflow. Don't compute the address of the object just
10903 before an array, as that's not portable. Use EMACS_INT, not
10904 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10905 * callint.c (Fcall_interactively):
10906 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10907 * callproc.c (call_process_kill, Fcall_process):
10908 Don't assume pid_t fits into an Emacs fixnum.

10918 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10919 (casify_object): Avoid integer overflow when overallocating buffer.
10920 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10921 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10922 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10923 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10924 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

10927 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10928 For CCL_MapSingle, check that content and value are in int range.
10929 (ccl_driver, Fregister_code_conversion_map):
10930 Check that Vcode_version_map_vector is a vector.
10931 (resolve_symbol_ccl_program): Check that vector header is in range.
10932 Always copy the vector, so that we can check its contents reliably
10933 now rather than having to recheck each instruction as it's being
10934 executed. Check that vector words fit in 'int'.
10935 (ccl_get_compiled_code, Fregister_ccl_program)
10936 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for

10941 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10942 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10943 Accept and return EMACS_INT, not int, because callers can pass values

10950 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10952 avoid mishandling large integers.

10961 Remove now-unnecessary CHECK_NATNUMs.
10962 (Fdefine_charset_internal): Check ranges here, more carefully.
10963 Don't rely on undefined behavior with signed left shift overflow.
10964 Don't assume unsigned int fits into fixnum, or that fixnum fits
10965 into unsigned int. Don't require max_code to be a valid fixnum;
10966 that's not true for gb10830 4-byte on a 32-bit host. Allow
10967 invalid_code to be a cons, for the same reason. Require code_offset
10968 to be a character. Avoid int overflow if max_char is close
10970 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10971 this is intended anyway and avoids some undefined behavior.
10972 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10973 INDEX_TO_CODE_POINT, as that's what it expects.
10974 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10975 * charset.h (DECODE_CHAR): Return int, not unsigned;
10976 this is what was intended anyway, and it avoids undefined behavior.
10977 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10978 integer-overflow issues.
10979 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10980 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10981 where the argument is EMACS_INT, and this behavior is not intended.
10982 * chartab.c (Fmake_char_table, Fset_char_table_range)
10983 (uniprop_get_decoder, uniprop_get_encoder):
10984 Don't assume fixnum fits in int.
10985 * cmds.c (move_point): New function, that does the gist of
10986 Fforward_char and Fbackward_char, but does so while checking
10987 for integer overflow more accurately.
10988 (Fforward_char, Fbackward_char): Use it.
10989 (Fforward_line, Fend_of_line, internal_self_insert)
10990 (internal_self_insert):
10991 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11641 may come from Lisp.

11650 2012-05-25 Glenn Morris <rgm@gnu.org>
11652 * lisp.mk (lisp): Update for more files being compiled now.
11654 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11656 * lread.c: Remove `read_pure' which makes no difference.
11657 (read_pure): Remove var.
11658 (unreadpure): Remove function.
11659 (readevalloop): Don't call read_list with -1 flag.
11660 (read1, read_vector): Don't test read_pure any more.

11672 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11674 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11677 This directory predates autoconf and is no longer needed nowadays.
11678 Move its few remaining bits of functionality to where they're needed.
11679 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

11689 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11690 (BITS_PER_EMACS_INT): New constants, replacing
11691 what used to be in config.h, but not useful in #if.
11692 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11693 define them any more.
11694 (VAL_MAX): New macro.
11696 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11697 BITS_PER_EMACS_INT, in #if.
11698 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11699 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11700 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11701 * s/ms-w32.h (DATA_START):
11702 Move here from removed file m/intel386.h.
11703 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11704 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11706 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11708 Assume C89 or later.
11709 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11710 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11712 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

11731 2012-05-19 Ken Brown <kbrown@cornell.edu>
11733 * xfns.c (x_in_use): Remove `static' qualifier.
11734 * xterm.h (x_in_use): Declare.
11735 * xgselect.c: Include xterm.h.
11736 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11737 and `display_arg' (bug#9754).
11739 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11741 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.

11746 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11748 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11750 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11751 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11753 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11754 reference to image_cache->refcount.
11755 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11757 2012-05-17 Juri Linkov <juri@jurta.org>
11759 * search.c (Fword_search_regexp, Fword_search_backward)
11760 (Fword_search_forward, Fword_search_backward_lax)
11761 (Fword_search_forward_lax): Move functions to isearch.el
11762 (bug#10145, bug#11381).
11764 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11766 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11768 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11770 * lread.c (init_obarray): Declare Qt and Qnil as special.
11772 2012-05-14 Glenn Morris <rgm@gnu.org>
11774 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11775 Put "libexec" before "bin", for the sake of init_callproc_1.
11777 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11779 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11781 * unexaix.c: Port to more-recent AIX compilers.
11782 (report_error, report_error_1, make_hdr, copy_sym)
11783 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11784 Make arguments const char *, not char *, to avoid violations of C
11785 standard and to fix some AIX warnings reported by Gilles Pion.
11787 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11789 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11790 already have overlays loaded.
11791 (handle_single_display_spec): Before returning without displaying
11792 fringe bitmap, synchronize the bidi iterator with the main display
11793 iterator, by calling iterate_out_of_display_property.
11794 (iterate_out_of_display_property): Detect buffer iteration by
11795 testing that it->string is a Lisp string.
11796 (get_next_display_element): When the current object is exhausted,
11797 and there's something on it->stack, call set_iterator_to_next to
11798 proceed with what's on the stack, instead of returning zero.
11799 (set_iterator_to_next): If called at the end of a Lisp string,
11800 proceed to consider_string_end without incrementing string
11801 position. Don't increment display vector index past the end of
11802 the display vector. (Bug#11417)
11803 (pos_visible_p): Don't report a position visible when move_it_to
11804 stopped at the last line of window, which happens to be scanned
11805 backwards by the bidi iteration. (Bug#11464)
11807 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11809 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11810 and right-margin display specs even if the spec is invalid or we
11811 are on a TTY, and thus unable to display on the fringes.
11812 That's because the text with the property will not be displayed anyway,
11813 so we need to signal to the caller that this is a "replacing"
11814 display spec. This fixes display when the spec is invalid or we
11817 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11819 * unexaix.c (make_hdr): Fix typo in prototype.
11820 This bug broke the build on AIX. Problem reported by Gilles Pion.
11822 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11824 * keyboard.c (kbd_buffer_get_event): Read special events also in
11825 batch mode. (Bug#11415)
11827 2012-05-12 Glenn Morris <rgm@gnu.org>
11829 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11831 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11833 * lisp.mk (lisp): Add newcomment.elc.
11835 2012-05-12 Glenn Morris <rgm@gnu.org>
11837 * Makefile.in (MKDIR_P): New, set by configure.
11838 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11840 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11842 Remove unused function hourglass_started.
11843 * dispextern.h (hourglass_started):
11844 * w32fns.c (hourglass_started):
11845 * xdisp.c (hourglass_started): Remove.
11847 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11849 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11850 Update dependencies.
11852 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11854 * xgselect.c (xg_select): Put maxfds+1 into a var.
11855 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11857 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11859 2012-05-10 Dave Abrahams <dave@boostpro.com>
11861 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11862 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11864 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11866 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11867 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11868 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11869 Initialize xd_registered_buses.
11871 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11873 Untag more efficiently if USE_LSB_TAG.
11874 This is based on a proposal by YAMAMOTO Mitsuharu in
11875 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11876 For an admittedly artificial (nth 8000 longlist) benchmark on
11877 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11878 Emacs's overall text size by 1%.
11879 * lisp.h (XUNTAG): New macro.
11880 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11881 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11882 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11883 * eval.c (Fautoload):
11884 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11885 * frame.h (XFRAME): Use XUNTAG.
11887 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11888 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11889 Remove unportable assumptions about print widths of types like
11891 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11892 intptr_t when converting between pointer and integer, to avoid GCC
11893 warnings about wrong width.
11895 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11897 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11898 stack for each reader_thread, instead of defaulting to 8MB
11899 determined by the linker. This avoids failures in creating
11900 subprocesses on Windows 7, see the discussion in this thread:
11901 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11903 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11905 Fix up display of the *Minibuf-0* buffer in the mini window.
11906 * keyboard.c (read_char): Don't clear the echo area if there's no
11908 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11909 contents of *Minibuf-0*) if there's no message displayed in its stead.
11911 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11913 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11916 2012-05-06 Chong Yidong <cyd@gnu.org>
11918 * lisp.mk (lisp): Update.
11920 2012-05-05 Jim Meyering <meyering@redhat.com>
11922 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11924 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11926 * data.c (PUT_ERROR): New macro.
11927 (syms_of_data): Use it. Add new error type `user-error'.
11928 * undo.c (user_error): New function.
11929 (Fprimitive_undo): Use it.
11930 * print.c (print_error_message): Adjust print style for `user-error'.
11931 * keyboard.c (user_error): New function.
11932 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11934 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11936 Do not limit current-time-string to years 1000..9999.
11937 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11938 (Fcurrent_time_string): Support any year that is supported by the
11939 underlying localtime representation. Don't use asctime, as it
11940 has undefined behavior for years outside the range -999..9999.
11942 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11944 Fix race conditions involving setenv, gmtime, localtime, asctime.
11945 Without this fix, interrupts could mess up code that uses these
11946 nonreentrant functions, since setting TZ invalidates existing
11947 tm_zone or tzname values, and since most of these functions return
11948 pointers to static storage.
11949 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11950 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11951 Grow the critical sections to include not just invoking
11952 localtime/gmtime, but also accessing these functions' results
11953 including their tm_zone values if any, and any related TZ setting.
11954 (format_time_string): Last arg is now struct tm *, not struct tm **,
11955 so that the struct tm is saved in the critical section.
11956 All callers changed. Simplify allocation of initial buffer, partly
11957 motivated by the fact that memory allocation needs to be outside
11958 the critical section.
11960 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11962 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11963 with RESET_INTERVAL.

11974 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11976 * xdisp.c (pos_visible_p): If already at a newline from the
11977 display string before the 'while' loop, don't walk back the glyphs
11978 from it3.glyph_row. Solves assertion violation when the display
11979 string begins with a newline (egg.el). (Bug#11367)
11981 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11983 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):

11989 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11990 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11991 All were removed before 23.1.
11993 * dispnew.c: Remove HAVE_LIBNCURSES test;
11994 it is always true on relevant platforms.
11996 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11997 Rename from LD_SWITCH_X_SITE_AUX_RPATH.

12009 Do not avoid creating empty evaporating overlays (Bug#9642).
12010 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12011 That is, do not delete an evaporating overlay if it becomes
12012 empty after its bounds are adjusted to fit within its buffer.
12013 This fix caused other problems, and I'm reverting it until we get
12014 to the bottom of them.
12016 2012-04-27 Chong Yidong <cyd@gnu.org>
12018 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12020 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12022 * xdisp.c (pos_visible_p): If the window start position is beyond
12023 ZV, start the display from buffer beginning. Prevents assertion
12024 violation in init_iterator when the minibuffer window is scrolled
12025 via the scroll bar.
12027 * window.c (window_scroll_pixel_based): Likewise.
12029 2012-04-27 Chong Yidong <cyd@gnu.org>
12031 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12033 2012-04-27 Glenn Morris <rgm@gnu.org>
12035 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12036 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12038 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12040 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12041 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12043 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12045 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12046 display element, check also the underlying string or buffer
12047 character. (Bug#11341)
12049 * w32menu.c: Include w32heap.h.
12050 (add_menu_item): If the call to AppendMenuW (via
12051 unicode_append_menu) fails, disable Unicode menus only if we are
12052 running on Windows 9X/Me.
12054 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12056 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12057 (xgetint): Add missing shift for LSB tags.
12059 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12061 * keyboard.c (read_char): Don't wipe echo area for select window
12062 events: These might get delayed via `mouse-autoselect-window'

12067 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12068 manipulation of :loaded-from data.
12070 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12072 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12073 now a cons (bug#11311).
12075 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12077 Do not create empty overlays with the evaporate property (Bug#9642).
12078 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12079 if it becomes empty after its bounds are adjusted to fit within
12080 its buffer. Without this fix, in a nonempty buffer (let ((o
12081 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12082 yields an empty overlay that has the evaporate property, which is
12083 not supposed to happen.
12085 Fix minor GTK3 problems found by static checking.
12086 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

12105 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12106 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12107 (__malloc_size_t, __malloc_ptrdiff_t):
12108 Remove. All uses removed, replaced by the definiens if needed,
12109 since we can assume C89 or better now.

12118 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12119 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12120 Define using prototypes, not old style.

12185 * alloc.c: Handle unusual debugging option combinations.
12186 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
12187 since the two debugging options are incompatible.
12188 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

12198 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12200 * sysdep.c [__FreeBSD__]: Minor cleanups.
12201 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12202 Use Emacs indenting style more consistently. Avoid some casts.
12203 Use 'double' consistently rather than mixing 'float' and 'double'.
12205 2012-04-21 Eduard Wiebe <usenet@pusto.de>
12207 * sysdep.c (list_system_processes, system_process_attributes):

12214 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12216 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12217 It is never used otherwise.
12219 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12221 * print.c (print_preprocess): Only check print_depth if print-circle
12223 (print_object): Check for cycles even when print-circle is nil and
12224 print-gensym is t, but only check print_depth if print-circle is nil.
12226 2012-04-20 Chong Yidong <cyd@gnu.org>
12228 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12229 set the status to "failed" and ensure that sentinel is run.
12231 2012-04-20 Glenn Morris <rgm@gnu.org>
12233 * process.c (Fset_process_inherit_coding_system_flag)

12286 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12287 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12288 (NEED_MEM_INSERT): New macro.
12289 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12290 Remove one incorrect comment and fix another.

12294 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
12295 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
12296 (r_alloc_sbrk): Now static.
12298 Improve ralloc.c interface checking.
12299 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
12300 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

12326 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12327 * s/netbsd.h, s/sol2-6.h:
12328 Remove definition of GC_MARK_STACK, since the default now works.
12329 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12330 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12331 no longer the default.
12332 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12334 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12336 * lread.c (lisp_file_lexically_bound_p):

12357 2012-04-11 Daniel Colascione <dancol@dancol.org>
12359 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12360 against is gone. It's better to use vfork now so that when Cygwin
12361 gains a new, working vfork, we use it automatically (bug#10398).
12363 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12383 * w32.c (w32_delayed_load): Record the full path of the library
12384 being loaded (bug#10424).
12386 2012-04-09 Glenn Morris <rgm@gnu.org>
12388 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12389 not just in the obarray, before snarfing them. (Bug#11036)
12391 * Makefile.in ($(leimdir)/leim-list.el):
12392 Pass EMACS rather than BUILT_EMACS.
12394 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12396 * process.c (make_process):
12397 * process.h: Add integer `gnutls_handshakes_tried' member to
12400 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
12401 Add convenience `GNUTLS_LOG2i' macro.
12403 * gnutls.c (gnutls_log_function2i): Convenience log function.
12404 (emacs_gnutls_read): Use new log functions,
12405 `gnutls_handshakes_tried' process member, and
12406 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12407 attempts per process (connection).
12409 2012-04-09 Chong Yidong <cyd@gnu.org>
12411 * eval.c (Fuser_variable_p, user_variable_p_eh)

12416 * minibuf.c (Fread_variable): Callers changed.
12418 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12420 * xdisp.c (set_cursor_from_row): If the display string appears in
12421 the buffer at position that is closer to point than the position
12422 after the display string, display the cursor on the first glyph of
12423 the display string. Fixes cursor display when a 'display' text
12424 property immediately follows invisible text. (Bug#11094)
12426 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12428 composite.c: use 'double' consistently
12429 * composite.c (get_composition_id): Use 'double' consistently
12430 instead of converting 'float' to 'double' and vice versa; this is
12431 easier to understand and avoids a GCC warning.
12433 2012-04-09 Glenn Morris <rgm@gnu.org>
12435 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12436 preparation for dumping it with emacs. (Bug#4789)
12437 (leimdir): New variable.
12438 ($(leimdir)/leim-list.el): New rule.
12439 (emacs$(EXEEXT)): Depend on leim-list.el.

12457 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12458 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12459 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12460 objects, as mark_maybe_pointer will catch them otherwise.
12461 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12462 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12469 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12471 Support building on MS-Windows with libxml2.
12473 * makefile.w32-in (OBJ2): Add xml.$(O).
12474 (GLOBAL_SOURCES): Add xml.c.
12475 ($(BLD)/xml.$(O)): New dependency list.
12477 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12478 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12479 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12480 [!WINDOWSNT]: New macros.
12481 (init_libxml2_functions, libxml2_loaded_p): New functions.
12482 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12483 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12484 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12485 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12487 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12488 Call init_libxml2_functions before calling libxml2 functions.
12489 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12491 * emacs.c: Don't include libxml/parser.h.
12492 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12493 xmlCleanupParser directly.
12495 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12497 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12499 * indent.c (Fvertical_motion): If there is a display string at
12500 point, use it.vpos to compute how many lines to backtrack after
12501 move_it_to point. (Bug#11133)
12503 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12505 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12506 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12507 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12508 macros related to unification of CJK characters. For the details,
12509 see the discussion following the message here:
12510 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12512 2012-04-04 Chong Yidong <cyd@gnu.org>
12514 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12516 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12518 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12519 instead of alloca. (Bug#11138)
12521 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12523 * w32menu.c (is_simple_dialog): Properly check lisp types.
12526 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12528 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12529 position we get to after a call to move_it_to fails the
12530 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12531 only if we wind up in a string from display property. (Bug#11063)
12533 * window.c (Fdelete_other_windows_internal): Invalidate the row
12534 and column information about mouse highlight, so that redisplay
12535 restores it after reallocating the glyph matrices. (Bug#7464)
12537 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12538 string comes from a `display' text property, use the buffer
12539 position of that property as if we actually saw that position in
12541 (move_it_by_lines): Remove the assertion that
12542 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12543 violated when there's a before-string at the beginning of a line.
12546 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12548 * xdisp.c (append_space_for_newline): If the default face was
12549 remapped, use the remapped face for the appended newline.
12550 (extend_face_to_end_of_line): Use the remapped default face for
12551 extending the face to the end of the line.
12552 (display_line): Call extend_face_to_end_of_line when the default
12553 face was remapped. (Bug#11068)
12555 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12557 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12559 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12561 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12563 2012-03-27 Glenn Morris <rgm@gnu.org>
12565 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12568 2012-03-26 Kenichi Handa <handa@m17n.org>
12570 * dispextern.h (struct glyph): Fix previous change. Change the
12571 bit length of glyphless.ch to 25 (Bug#11082).
12573 2012-03-26 Chong Yidong <cyd@gnu.org>
12575 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12576 (command_loop_1): Use it; inhibit selection update for
12577 handle-select-window too (Bug#8996).
12579 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12581 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12583 2012-03-25 Kenichi Handa <handa@m17n.org>
12585 * dispextern.h (struct glyph): Change the bit length of
12586 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12588 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12590 * s/ms-w32.h (tzname): Include time.h before redirecting to
12591 _tzname. Fixes the MSVC build. (Bug#9960)
12593 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12595 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12598 * xterm.c (XTread_socket): Only modify handling_signal if
12599 !SYNC_INPUT. (Bug#11080)
12601 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12603 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12604 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12605 when fetching a multibyte character consumes more bytes than
12606 CHAR_BYTES returns, due to unification of CJK characters in
12607 string_char. (Bug#11073)
12609 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12611 * process.c (wait_reading_process_output): Handle pty disconnect
12612 by refraining from sending oneself a SIGCHLD (bug#10933).
12614 2012-03-22 Chong Yidong <cyd@gnu.org>

12619 Mark string as coming from a prefix property.
12620 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12621 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12623 2012-03-21 Chong Yidong <cyd@gnu.org>
12625 * xfaces.c (Vface_remapping_alist): Doc fix.
12627 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12629 * w32proc.c (Fw32_set_console_codepage)
12630 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12633 2012-03-20 Chong Yidong <cyd@gnu.org>
12635 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12636 to reflect default non-nil value of redisplay-dont-pause.
12638 2012-03-19 Kenichi Handa <handa@m17n.org>
12640 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12641 it fit in a valid range (Bug#11003).
12643 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12645 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12646 that is not from display property, accept the row as a "cursor
12647 row" if one of the string's character has a non-nil `cursor'
12648 property. Fixes cursor positioning when there are newlines in
12649 overlay strings, e.g. in icomplete.el. (Bug#11035)
12651 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12653 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12655 2012-03-12 Chong Yidong <cyd@gnu.org>
12657 * eval.c (inhibit_lisp_code): Rename from
12658 inhibit_window_configuration_change_hook; move from window.c.
12660 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12661 * window.c (run_window_configuration_change_hook)
12662 (syms_of_window): Callers changed.
12664 2012-03-11 Chong Yidong <cyd@gnu.org>

12668 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12670 2012-03-10 Chong Yidong <cyd@gnu.org>
12672 * frame.c (other_visible_frames): Don't assume the selected frame
12673 is visible (Bug#10955).
12675 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12677 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
12679 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
12681 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12682 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12685 2012-03-03 Glenn Morris <rgm@gnu.org>
12687 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12689 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12691 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12692 position past the first glyph_row that ends at ZV. (Bug#10902)
12693 (redisplay_window, next_element_from_string): Fix typos in
12695 (redisplay_window): Pass to move_it_vertically the margin in
12696 pixels, not in screen lines.
12698 2012-03-02 Glenn Morris <rgm@gnu.org>
12700 * buffer.c (buffer-list-update-hook): Doc fix.
12702 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12704 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12705 push_it before setting up the iterator for the first overlay
12706 string, even if we have an empty string loaded.
12707 (next_overlay_string): If there's an empty string on the iterator
12708 stack, pop the stack. (Bug#10903)
12710 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12712 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12713 Suggested by Stefan Monnier in
12714 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12715 * alloc.c (widen_to_Lisp_Object): New static function.
12716 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12717 and widening them to Lisp_Objects. This would work even if
12718 USE_LSB_TAG is defined and wide integers are used, which might
12719 happen in a future version of Emacs.
12721 2012-02-25 Chong Yidong <cyd@gnu.org>
12723 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12726 * xselect.c (Fx_selection_exists_p): Doc fix.
12727 (x_clipboard_manager_save_all): Print an informative message
12728 before saving to clipboard manager.
12730 2012-02-24 Chong Yidong <cyd@gnu.org>
12732 * keyboard.c (process_special_events): Handle all X selection
12733 requests in kbd_buffer, not just the next one (Bug#8869).
12735 2012-02-23 Chong Yidong <cyd@gnu.org>
12737 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12738 call when setting menu-bar-lines and tool-bar-lines parameters.
12739 (unwind_create_frame_1): New helper function.
12741 * window.c (inhibit_window_configuration_change_hook): New var.

12760 when computing $valmask.
12762 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12763 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12764 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12765 It's useless in that case, and it can cause problems on hosts
12766 that allocate halves of EMACS_INT values separately.
12767 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12768 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12769 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12770 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12771 it avoids undefined behavior on hosts where shifting right by more
12772 than the word width has undefined behavior.
12774 2012-02-19 Chong Yidong <cyd@gnu.org>
12776 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12777 (Funhandled_file_name_directory, Ffile_name_as_directory)
12778 (Fdirectory_file_name, Fexpand_file_name)
12779 (Fsubstitute_in_file_name): Protect against invalid file handler
12780 return values (Bug#10845).
12782 2012-02-18 Eli Zaretskii <eliz@gnu.org>
12784 * .gdbinit (pitx): Fix incorrect references to fields of the
12787 2012-02-17 Chong Yidong <cyd@gnu.org>

12791 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
12793 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
12794 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12796 2012-02-15 Chong Yidong <cyd@gnu.org>
12798 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12799 marked as special. Also, starting docstrings with * is obsolete.

12812 * keymap.c (Fsingle_key_description): Handle char ranges.
12814 2012-02-12 Chong Yidong <cyd@gnu.org>
12816 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12817 as that creates a dangerous corner case.
12819 * window.c (Fdelete_window_internal): Invalidate the mouse
12820 highlight (Bug#9904).
12822 2012-02-12 Glenn Morris <rgm@gnu.org>
12824 * xselect.c (Fx_own_selection_internal)
12825 (Fx_get_selection_internal, Fx_disown_selection_internal)
12826 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12827 * nsselect.m (Fx_own_selection_internal)
12828 (Fx_disown_selection_internal, Fx_selection_exists_p)
12829 (Fx_selection_owner_p, Fx_get_selection_internal):
12830 Sync docs and argument specs with the xselect.c versions.
12832 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12834 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
12836 2012-02-11 Eli Zaretskii <eliz@gnu.org>
12838 * w32select.c (Fx_selection_exists_p): Sync doc string and
12839 argument list with xselect.c. (Bug#10783)
12841 * w16select.c (Fx_selection_exists_p): Sync doc string and
12842 argument list with xselect.c. (Bug#10783)

12850 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
12852 2012-02-07 Chong Yidong <cyd@gnu.org>
12854 * buffer.c (Fbuffer_local_variables)
12855 (buffer_lisp_local_variables): Handle unbound vars correctly;
12856 don't let Qunbound leak into Lisp.

13389 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13390 verifies glyph row's hash code--we have just reallocated the
13391 glyphs, so their contents can be complete garbage. (Bug#10164)

13437 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13438 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13439 this macro definition.

13470 (start_display): Don't move to the next line if the display should
13471 start at a newline that is part of a display vector or an overlay

13555 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13556 is set, removing the need for VIRT_ADDRESS_VARIES.
13557 (PURE_P): Use a more-efficient implementation that needs just one
13558 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13559 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13560 to 4 (xorl, subq, cmpq, setbe).
13561 * alloc.c (pure): Always extern now, since that's the

13563 (PURE_POINTER_P): Use a single comparison, not two, for
13564 consistency with the new puresize.h.
13565 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13566 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13572 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13573 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13574 behave as if the cursor position were at the window margin.
13576 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13577 and the cursor position is out of bounds, behave as if the cursor
13578 position were at the window margin. (Bug#10075)
13580 2011-11-18 Chong Yidong <cyd@gnu.org>
13582 * window.c (Fwindow_combination_limit): Make first argument

13601 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13603 * xdisp.c (row_hash): New function, body extracted from
13604 compute_line_metrics.
13605 (compute_line_metrics): Call row_hash, instead of computing the
13608 * dispnew.c (verify_row_hash): Call row_hash for computing the
13609 hash code of a row, instead of duplicating code from xdisp.c.
13611 * dispextern.h (row_hash): Add prototype.
13613 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13615 * frame.c (delete_frame): Don't delete the terminal when the last

13641 (Fsplit_window_internal, saved_window)
13642 (Fset_window_configuration, save_window_save): Rename all

13649 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13651 * xdisp.c (display_line): Move the call to
13652 highlight_trailing_whitespace before the call to
13653 compute_line_metrics, since the latter needs to see the final
13654 faces of all the glyphs to compute ROW's hash value.
13655 Fixes assertion violations in row_equal_p. (Bug#10035)
13657 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13659 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

13664 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13665 with user-defined heap size. Bump the default size of the temacs

13669 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13670 current_matrix and desired_matrix. (Bug#9990)
13671 (verify_row_hash) [XASSERTS]: New function.

13718 Avoid some portability problems by eschewing 'extern inline' functions.
13719 The trivial performance wins aren't worth the portability hassles; see
13720 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13722 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

13797 (window_box_right, window_box_right_offset): Declare extern.
13798 Otherwise, these inline functions do not conform to C99 and
13799 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13800 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13801 * intervals.c (adjust_intervals_for_insertion)
13802 (adjust_intervals_for_deletion): Now extern, because otherwise the

13804 (static_offset_intervals): Remove.
13805 (offset_intervals): Rewrite using the old contents of
13806 static_offset_intervals. The old version didn't conform to C99
13807 because an extern inline function contained a reference to an
13808 identifier with static linkage.

14060 * process.c (make_process): Set gnutls_state to NULL.
14062 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14063 non-NULL, regardless of GNUTLS_INITSTAGE.

14112 (bidi_resolve_weak): Don't enter the expensive loop if the current
14113 position is before next_en_pos. Record the bidi type of the first
14114 non-ET, non-BN character we find, in addition to its position.
14115 (bidi_level_of_next_char): Invalidate next_en_type when
14116 next_en_pos is over-stepped.
14118 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14120 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14121 * editfns.c: Rewrite current-time-zone so that it invokes
14122 the equivalent of (format-time-string "%Z") to get the time zone name.
14123 This fixes a bug when the time zone name contains characters that
14124 need converting from the system time locale to Emacs internal format.
14125 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14126 that patch fixed format-time-string to do the conversion, but
14127 I forgot to fix current-time-zone.
14128 (format_time_string): New function, containing most of
14129 what Fformat_time_string used to contain.
14130 (Fformat_time_string): Rewrite in terms of format_time_string.
14131 This doesn't change this function's behavior.
14132 (current-time-zone): Rewrite to use format_time_string.
14133 This fixes the bug reported by Michael Schierl in
14134 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14135 Jason Rumney's 2007-06-07 change worked around this bug, but
14137 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14139 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14141 * xdisp.c (start_display): If the character at POS is displayed
14142 via a display vector, reset IT->current.dpvec_index to zero.
14143 (try_window_reusing_current_matrix): If a line ends in a display
14144 vector or the next line starts in a display vector, continue
14145 redrawing the window even though the character position of
14146 start_row was reached.
14149 2011-10-18 Chong Yidong <cyd@gnu.org>
14151 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14152 with nobreak-char-display too.
14154 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14156 Fix part 3 of bug#9771.
14157 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14158 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14159 non-neutral characters if the current character is a paragraph
14160 separator (a.k.a. Newline). This avoids running the same
14161 expensive loop twice, once when we consume the preceding newline
14162 and the other time when the line actually needs to be displayed.
14163 Avoid the loop when we see neutrals on the base embedding level
14164 following a character whose directionality is the same as the
14165 paragraph's. This avoids running the expensive loop when a line
14166 ends in a long sequence of neutrals, like control characters.
14167 Add assertion against STRONG_AL type. Slightly rearrange code
14168 that determines the type of a neutral given the first non-neutral
14170 (bidi_level_of_next_char): Set next_en_pos to zero when
14171 invalidating its info.
14173 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14175 * xdisp.c (push_display_prop): Determine whether to record string
14176 or buffer position by IT->string, not by IT->method. Allow
14177 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14178 (move_it_vertically_backward): Don't look for character position
14179 immediately after the newline when in a continuation line.
14182 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14184 * window.c (coordinates_in_window): Rewrite and delabelize
14185 vertical border check. (Bug#5357) (Bug#9618)

14189 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14190 errors in XSetWindowBorder (bug#9310).
14192 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14194 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14195 avoid crash when xmalloc overrun checking is enabled.
14197 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14199 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14200 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14201 cursor motion with <left> and <right> arrow keys.
14203 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14204 some callers set that themselves.
14206 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14208 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14209 display string and the previous row comes from the same string and
14210 is empty. (Bug#9739) (Bug#9738)
14212 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14214 * doc.c (get_doc_string): Encode file name (bug#9735).

14218 * bidi.c (bidi_level_of_next_char):

14220 comments regarding the Unicode Line Separator character.
14222 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14224 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

14230 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14232 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14233 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14235 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14236 Some packages use them to denote characters with modifiers.
14238 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14240 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14241 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14242 matching a pp-number. Rename parameter var to var1.
14244 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14246 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).

14250 * callint.c (Fcall_interactively): Give a more explicit error for the
14251 'c' case with a non-character input. (Bug#8479)

14255 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14257 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14258 lines that are hscrolled on the left.
14260 * dispnew.c (buffer_posn_from_coords): Account for a possible
14261 presence of header-line. (Bug#4426)
14263 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14265 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14266 Don't advertise functionality which we discourage or doesn't work.
14268 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14270 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14271 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14272 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14273 this makes Emacs dump core during garbage collection on rare
14274 occasions. sizeof is obviously inferior to offsetof here, so
14275 stick with offsetof.
14276 (GC_POINTER_ALIGNMENT): New macro.
14277 (mark_memory): Omit 3rd (offset) arg; caller changed.
14278 Don't assume EMACS_INT alignment is the same as pointer alignment.
14280 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14282 * keyboard.c (read_key_sequence_remapped): New var.
14283 (read_key_sequence): Compute remapping in the right buffer.
14284 (command_loop_1): Use read_key_sequence's remapping directly.
14286 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14288 * dired.c (file_name_completion): Don't expand file name.
14289 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14290 before checking file name handler.
14292 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14293 they've been requested explicitly (bug#9591).
14295 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14297 * keymap.c (Fsingle_key_description): Use make_specified_string
14298 instead of build_string to build string from push_key_description.
14301 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14303 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14304 This fixes a Y2038 bug on 64-bit hosts.
14305 * buffer.c (reset_buffer):
14306 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14307 (Fclear_buffer_auto_save_failure):
14308 Use 0, not -1, to represent an unset failure time, since time_t
14309 might not be signed.
14311 Remove dependency on glibc malloc internals.
14312 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14313 Move back here from lisp.h, but with their new implementations.
14314 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14315 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14316 * charset.c (charset_table_init): New static var.
14317 (syms_of_charset): Use it instead of xmalloc. This removes a
14318 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14319 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14320 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14321 Move back to alloc.c.
14322 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14323 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14325 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14327 * nsterm.m (windowDidResize): Call x_set_window_size only when
14328 ns_in_resize is true. Otherwise set pixelwidth/height and
14329 call change_frame_size (Bug#9628).
14331 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14333 Port --enable-checking=all to Fedora 14 x86-64.
14334 * charset.c (syms_of_charset): Also account for glibc malloc's
14335 internal overhead when calculating the initial malloc maximum.
14337 Port --enable-checking=all to Fedora 14 x86.
14338 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14340 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14341 (overrun_check_realloc, overrun_check_free):
14342 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14343 That way, xmalloc returns a properly-aligned pointer even if
14344 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14345 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14346 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14347 into account when calculating the initial malloc maximum.
14348 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14349 Move here from alloc.c, so that charset.c can use it too.
14350 Properly align; the old code wasn't right for common 32-bit hosts
14351 when configured with --enable-checking=all.
14352 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14353 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14355 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14357 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14360 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14362 * xdisp.c (compute_display_string_end): If there's no display
14363 string at CHARPOS, return -1.
14365 * bidi.c (bidi_fetch_char): When compute_display_string_end
14366 returns a negative value, treat the character as a normal
14367 character not covered by a display string. (Bug#9624)
14369 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14371 * lread.c (Fread_from_string): Fix typo in docstring.
14373 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14375 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14376 newline, reseat the iterator instead of bidi-iterating there one
14377 character at a time. (Bug#9610)
14378 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14379 TO_CHARPOS if the bidi iterator is at base embedding level.
14381 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14383 * lread.c (readevalloop): Use correct code for NBSP.
14384 (read1): Likewise. (Bug#9608)
14386 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14388 * dbusbind.c (Fdbus_register_signal): When service is not
14389 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14391 2011-09-25 Glenn Morris <rgm@gnu.org>
14393 * buffer.c (truncate-lines): Doc fix.
14395 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14397 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14398 (Fset_window_next_buffers): Doc fix.
14400 2011-09-24 Glenn Morris <rgm@gnu.org>
14402 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14404 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14406 Fix minor problems found by static checking.
14407 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14408 * indent.c (Fvertical_motion): Fix == vs = typo.
14410 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14412 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14413 Default value is now t. Doc fix.
14415 * indent.c (Fvertical_motion): Compute and apply the overshoot
14416 logic when moving up, not only when moving down. Fix the
14417 confusing name and values of the it_overshoot_expected variable;
14418 logic changes accordingly. (Bug#9254) (Bug#9549)
14420 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14421 CHARPOS is covered by a display string which includes newlines.
14422 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14423 is covered by a display string with embedded newlines.
14425 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14427 * dbusbind.c (Fdbus_register_signal): Add match rule to
14428 Vdbus_registered_objects_table. (Bug#9581)
14429 (Fdbus_register_method, Vdbus_registered_objects_table):
14432 2011-09-24 Jim Meyering <meyering@redhat.com>
14434 do not ignore write error for any output size
14435 The previous change was incomplete.
14436 While it makes emacs --batch detect the vast majority of stdout
14437 write failures, errors were still ignored whenever the output size is
14438 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14439 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14440 && echo FAIL: ignored write error
14441 FAIL: ignored write error
14442 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14443 && echo FAIL: ignored write error
14444 FAIL: ignored write error
14445 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14447 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14449 * emacs.c (Fkill_emacs): In noninteractive mode exit
14450 non-successfully if a write error occurred on stdout. (Bug#9574)
14452 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14454 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14457 * dispextern.h (struct it): Update the comment documenting what
14460 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14462 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14463 a display string, extend search for cursor position to end of row.
14464 (find_row_edges): If the row ends in a newline from a display
14465 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14466 Handle the case of a display string with multiple newlines.
14467 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14468 non-empty line. Fixes confusing cursor motion with arrow keys at
14469 the beginning of a line that starts with whitespace.
14471 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14473 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14476 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14478 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14479 boolean (Bug#9154).
14481 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14483 * xdisp.c (display_line): Record maximum and minimum buffer
14484 positions even if no glyphs were produced (e.g., by a zero-width
14485 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14486 buffer positions that will be removed from the glyph row because
14488 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14489 column is beyond frame width: don't subtract 1 "pixel" when
14490 computing width of the stretch.
14491 (reseat_at_next_visible_line_start): Undo the change made on
14492 2011-09-17 that saved paragraph information and restored it after
14493 the call to `reseat'. (Bug#9545)
14495 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14497 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14498 and turn window cursor on if cleared (Bug#9415).
14500 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14502 * search.c (boyer_moore): Take unibyte characters from pattern
14503 literally. (Bug#9458)
14505 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14507 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14509 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14511 Fix minor problem found by static checking.
14512 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14513 initialized, to pacify gcc -Wuninitialized.
14515 * fileio.c: Report proper errno when syscall falls.
14516 (Finsert_file_contents): Save and restore errno,
14517 so that report_file_error outputs the correct diagnostic.
14518 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14520 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14522 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14524 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14526 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14527 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14529 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14531 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14532 about the current paragraph and restore it after the call to reseat.
14534 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14535 (bidi_find_paragraph_start): Search back for paragraph beginning
14536 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14537 (bidi_move_to_visually_next): Only trigger paragraph-related
14538 computations when the last character is a newline or at EOB, not
14539 just any NEUTRAL_B. (Bug#9470)
14541 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14542 truncated lines if point is covered by a display string. (Bug#9524)
14544 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14546 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14547 (cons_to_x_long): New function.
14548 (lisp_data_to_selection_data): Use it. Correct the test for
14549 short-versus-long data; it was negated. Break out of vector
14550 loop, for efficiency, when a long datum is discovered.
14552 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14554 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14556 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14558 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14559 GCC PR/17406) by declaring this function with external scope.
14561 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14563 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14564 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14566 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14568 * editfns.c (Fformat): Correctly handle text properties on "%%".
14570 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14572 * xterm.c (x_draw_composite_glyph_string_foreground):

14574 * term.c (encode_terminal_code):
14575 * composite.c (composition_update_it, get_composition_id):
14576 * xdisp.c (get_next_display_element)
14577 (fill_composite_glyph_string): Add comments about special meaning
14578 of TAB characters in a composition.
14580 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14582 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14583 This occurs when processing a multibyte format.
14584 Problem reported by Wolfgang Jenker.
14586 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14588 * xdisp.c (try_cursor_movement): Only check for exact match if
14589 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14591 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14593 Remove unused external symbols.
14594 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14595 * xdisp.c (calc_pixel_width_or_height): Now static.
14596 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14597 * indent.c (check_display_width):
14598 * w32term.c: Fix comment to match code.
14599 * xterm.c, xterm.h (x_catching_errors): Remove.
14601 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14603 * xselect.c: Use signed conversions more consistently (Bug#9498).
14604 (selection_data_to_lisp_data): Assume incoming selection data are
14605 signed integers, not unsigned. This is to be consistent with
14606 outgoing selection data, which was modified to use signed integers
14607 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14608 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14609 expects long, not unsigned long.
14611 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14613 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14614 computation of loop end. Reported by Johan Bockgård
14617 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14619 * frame.c (Fother_visible_frames_p): Function deleted.
14621 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14623 * indent.c (compute_motion): Process display vector front to back
14624 rather than the other way around. (Bug#2496)
14626 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14628 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14630 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14632 * minibuf.c (Fread_from_minibuffer): Doc fix.
14634 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14636 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14637 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14639 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14641 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14642 value for non-existent files.
14644 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14646 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14647 set its "size" to -1. This will set the modtime_size field of
14648 the corresponding buffer to -1, which is what
14649 verify-visited-file-modtime expects for files that do not exist.
14652 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14654 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14656 * lisp.h: ... from here. push_key_description is no longer
14657 defined in keyboard.c, so its declaration should not be in
14658 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14659 logically belongs with push_key_description.
14661 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14663 * buffer.h: Include <sys/types.h> instead of <time.h>.
14664 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14665 Problem reported by Herbert J. Skuhra.
14667 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14669 * xml.c (parse_region): Make the parsing work for
14670 non-comment-starting XML files again (bug#9144).
14672 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14674 * image.c (gif_load): Fix calculation of bottom and right corner.
14677 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14679 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14680 redisplay in small windows.
14682 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14684 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14686 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14688 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14689 Operate on live windows only.
14691 2011-09-08 Juanma Barranquero <lekktu@gmail.com>

14695 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14697 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14698 only under bidi iteration.
14700 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14702 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14704 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14706 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14707 Without this fix, the command to link temacs failed due to an
14708 undefined symbol __builtin_isnan. This is because
14709 /usr/include/iso/math_c99.h #defines isnan(x) to
14710 __builtin_isnan(x), but the bundled gcc, which identifies itself
14711 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14713 * floatfns.c (isnan): #undef, and then #define to a clone of
14715 (Fisnan): Always define, since it's always available now.
14716 (syms_of_floatfns): Always define isnan at the Lisp level.
14718 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14720 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14722 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14724 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14725 The previous code assumed that file offsets (off_t values) fit in
14726 EMACS_INT variables, which is not true on typical 32-bit hosts.
14727 The code messed up by falsely reporting buffer overflow in cases
14728 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14729 when "big" contains more than 2**29 bytes, even though this
14730 inserts just one byte and does not overflow the buffer.
14731 (Finsert_file_contents): Store file offsets as off_t
14732 values, not as EMACS_INT values. Check for overflow when
14733 converting between EMACS_INT and off_t. When checking for
14734 buffer overflow or for overlap, take the offsets into account.
14735 Don't use EMACS_INT for small values where int suffices.
14736 When checking for overlap, fix a typo: ZV was used where
14737 ZV_BYTE was intended.
14738 (Fwrite_region): Don't assume off_t fits into 'long'.
14739 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14741 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14743 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14745 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14747 sprintf-related integer and memory overflow issues (Bug#9412).
14749 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14750 (esprintf, exprintf, evxprintf): New functions.
14751 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14752 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14753 (modify_event_symbol): Do not assume that the length of
14754 name_alist_or_stem is safe to alloca and fits in int.
14755 (Fexecute_extended_command): Likewise for function name and binding.
14756 (Frecursion_depth): Wrap around reliably on integer overflow.
14757 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14758 since some callers pass EMACS_INT values.
14759 (Fsingle_key_description): Don't crash if symbol name contains more
14760 than MAX_ALLOCA bytes.
14761 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14762 (get_minibuffer): Arg is now EMACS_INT, not int.
14763 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14764 (esprintf, exprintf, evxprintf): New decls.
14765 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14767 * dbusbind.c (signature_cat): New function.
14768 (xd_signature, Fdbus_register_signal):
14769 Do not overrun buffer; instead, report string overflow.
14771 * dispnew.c (add_window_display_history): Don't overrun buffer.
14772 Truncate instead; this is OK since it's just a log.
14774 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14775 even if the time zone offset is outlandishly large.
14776 Don't mishandle offset == INT_MIN.
14778 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14779 when creating daemon; the previous buffer-overflow check was incorrect.
14781 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14782 which has the guts of the old verror function.
14784 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14785 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14787 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14788 (font_unparse_xlfd): Don't blindly alloca long strings.
14789 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14790 fits in int, when using sprintf. Use single snprintf to count
14791 length of string rather than counting it via multiple sprintfs;
14792 that's simpler and more reliable.
14793 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14794 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14795 sprintf, in case result does not fit in int.
14797 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14798 (fontset_from_font): Print it.
14800 * frame.c (tty_frame_count): Now printmax_t, not int.
14801 (make_terminal_frame, set_term_frame_name): Print it.
14802 (x_report_frame_params): In X, window IDs are unsigned long,
14803 not signed long, so print them as unsigned.
14804 (validate_x_resource_name): Check for implausibly long names,
14805 and don't assume name length fits in 'int'.
14806 (x_get_resource_string): Don't blindly alloca invocation name;
14807 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14810 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14811 (xg_check_special_colors, xg_set_geometry):
14812 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14814 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14815 Use esprintf, not sprintf, in case result does not fit in int.
14817 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14818 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14819 it as a large positive number.
14820 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14821 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14823 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14824 in case result does not fit in int.
14826 * print.c (float_to_string): Detect width overflow more reliably.
14827 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14828 buffer overrun. Don't assume list length fits in 'int'. Treat
14829 print length of 0 as 0, not as infinity; to be consistent with other
14830 uses of print length in this function. Don't overflow print length
14831 index. Don't assume hash table size fits in 'long', or that
14832 vectorlike size fits in 'unsigned long'.
14834 * process.c (make_process): Use printmax_t, not int, to format
14835 process-name gensyms.
14837 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14839 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14840 to avoid potential buffer overrun.
14842 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14843 if X resource line is longer than 512 bytes.
14845 * xfns.c (x_window): Make sprintf buffer a bit bigger
14846 to avoid potential buffer overrun.
14848 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14850 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14852 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14854 Integer overflow fixes for scrolling, etc.
14855 Without these, Emacs silently mishandles large integers sometimes.
14856 For example, "C-u 4294967297 M-x recenter" was treated as if
14857 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14859 * xdisp.c (try_window_id): Check Emacs fixnum range before
14860 converting to 'int'.
14862 * window.c (window_scroll_line_based, Frecenter):
14863 Check that an Emacs fixnum is in range before assigning it to 'int'.
14864 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14865 values converted from Emacs fixnums.
14866 (Frecenter): Don't wrap around a line count if it is out of 'int'
14867 range; instead, treat it as an extreme value.
14868 (Fset_window_configuration, compare_window_configurations):
14869 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14871 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14872 that can exceed INT_MAX. Check that EMACS_INT value is in range
14873 before assigning it to the (possibly-narrower) index.
14874 (match_limit): Don't assume that a fixnum can fit in 'int'.
14876 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14879 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14880 (Fvertical_motion): Don't wrap around LINES values that don't fit
14881 in 'int'. Instead, treat them as extreme values. This is good
14882 enough for windows, which can't have more than INT_MAX lines anyway.
14884 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14886 * Require libxml/parser.h to avoid compilation warning.
14888 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14890 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14891 since this reportedly can destroy thread storage.
14893 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14895 * syntax.c (find_defun_start): Update all cache variables if
14896 exiting early (Bug#9401).
14898 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14900 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14902 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14903 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14904 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14906 * term.c (tty_append_glyph): New function.
14907 (produce_stretch_glyph): Static function and its prototype deleted.
14909 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14912 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14914 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14915 when checking :margin (Bug#9390).
14916 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14917 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14918 so that the name doesn't mislead. All uses changed.
14920 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14922 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14925 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14927 * xdisp.c (move_it_to): Don't bail out early when reaching
14928 position beyond to_charpos, if we are scanning backwards.
14929 (move_it_vertically_backward): When DY == 0, make sure we get to
14930 the first character in the line after the newline.
14932 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14934 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14935 (ccl_driver): Do not generate an out-of-range pointer.
14936 (Fccl_execute_on_string): Remove unnecessary check for
14937 integer overflow, noted by Stefan Monnier in
14938 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14939 Remove a FIXME that didn't need fixing.
14940 Simplify the newly-introduced buffer reallocation code.
14942 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14944 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14946 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14948 Integer and memory overflow issues (Bug#9196).
14950 * doc.c (get_doc_string): Rework so that
14951 get_doc_string_buffer_size is the actual buffer size, rather than
14952 being 1 less than the actual buffer size; this makes xpalloc more
14955 * image.c (x_allocate_bitmap_record, cache_image):
14956 * xselect.c (Fx_register_dnd_atom):
14957 Simplify previous changes by using xpalloc.
14959 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14960 since either will do and ptrdiff_t is convenient with xpalloc.
14962 * charset.c (charset_table_size)
14963 (struct charset_sort_data.priority): Now ptrdiff_t.
14964 (charset_compare): Don't overflow if priorities differ greatly.
14965 (Fsort_charsets): Don't assume list length fits in int.
14966 Check for size-calculation overflow when allocating sort data.
14967 (syms_of_charset): Allocate an initial charset table that is
14968 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14970 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14972 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14973 The actual value is always <= INT_MAX, and leaving it unsigned made
14974 overflow checking harder.
14976 * dispextern.h (struct glyph_matrix.rows_allocated)
14977 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14978 with xpalloc. The values are still always <= INT_MAX.
14980 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14982 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14983 (SAFE_NALLOCA): New macro.
14985 * region-cache.c (struct boundary.pos, find_cache_boundary)
14986 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14987 (set_cache_region, invalidate_region_cache)
14988 (revalidate_region_cache, know_region_cache, region_cache_forward)
14989 (region_cache_backward, pp_cache):
14990 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14991 so that ptrdiff_t * can be passed to xpalloc.
14992 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14993 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14994 (pp_cache): Don't assume cache_len fits in int.
14995 * region-cache.h: Adjust extern decls to match.
14997 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14998 EMACS_INT, since either will do, for xpalloc.
15000 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15001 (xnmalloc, xnrealloc, xpalloc): New functions.
15003 * bidi.c (bidi_shelve_header_size): New constant.
15004 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15005 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15007 * bidi.c (bidi_cache_shrink):
15008 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15010 Don't update size of array until after memory allocation succeeds,
15011 because xmalloc/xrealloc may not return.
15012 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15013 now that we have proper integer overflow checking.
15014 (record_overlay_string, overlay_strings): Catch overflows when
15015 calculating size of overlay_str_buf.
15017 * callproc.c (Fcall_process): Check for size overflow when
15018 calculating size of args2.
15019 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15020 Normally we prefer signed values, but sticking with ptrdiff_t would
15021 require adding more-complicated checks.
15023 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15024 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15025 Redo buffer-overflow calculations to avoid integer overflow.
15026 Add a FIXME comment where memory seems to be over-allocated.
15028 * character.c (Fstring): Check for size-calculation overflow.
15030 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15031 unnecessary integer overflow. Check for size overflow.
15032 (encode_coding_object): Don't update size until xmalloc succeeds.
15034 * composite.c (get_composition_id): Check for overflow in glyph
15035 length calculations.
15037 Integer and memory overflow fixes for display code.
15038 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15039 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15040 (scrolling_window): Check for overflow in size calculations.
15041 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15042 Don't assume glyph table len fits in int.

15044 (row_table_size): Now ptrdiff_t, not int.
15045 (scrolling_window): Avoid overflow in size calculations.
15046 Don't update size until allocation succeeds.
15047 * fns.c (concat): Check for overflow in size calculations.
15048 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15049 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15050 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15052 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15053 (get_doc_string): Check for size calculation overflow.
15054 Don't update size until allocation succeeds.
15055 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15056 EMACS_INT, where ptrdiff_t will do.
15057 (Fsubstitute_command_keys): Check for string overflow.
15059 * editfns.c (set_time_zone_rule): Don't assume environment length
15061 (message_length): Now ptrdiff_t, not int.
15062 (Fmessage_box): Don't update size until allocation succeeds.
15063 Don't assume message length fits in int.
15064 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15066 * emacs.c (main): Do not reallocate argv, since there is a null at
15067 the end that can be overwritten, and this way there's no need to
15068 worry about size-calculation overflow.
15069 (sort_args): Check for size-calculation overflow.
15071 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15073 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15075 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15076 (x_set_scroll_bar_width, x_figure_window_size):
15077 Check for integer overflow.
15078 (x_set_alpha): Do not assume XINT fits in int.
15080 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15081 This is for the members text_lines, text_cols, total_lines, total_cols,
15082 where the system imposes an 'int' limit.
15084 * fringe.c (Fdefine_fringe_bitmap):
15085 Don't update size until alloc works.
15087 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15088 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15090 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15091 Check for size-calculation overflow.
15092 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15093 do, as we prefer signed integers.
15094 (id_to_widget.max_size, id_to_widget.used)
15095 (xg_store_widget_in_map, xg_remove_widget_from_map)
15096 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15097 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15098 Use and return ptrdiff_t, not int.
15099 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15100 * gtkutil.h: Change prototypes to match the above.
15102 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15103 are duplicate now that they've been promoted to lisp.h.
15104 (x_allocate_bitmap_record, x_alloc_image_color)
15105 (make_image_cache, cache_image, xpm_load):
15106 Don't update size until alloc is done.
15107 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15109 Check for size calculation overflow.
15110 (ct_colors_allocated_max): New constant.
15111 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15114 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15115 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15116 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15117 Use ptrdiff_t, not int, to count maps.
15118 (read_char_minibuf_menu_prompt): Check for overflow in size
15119 calculations. Don't update size until allocation succeeds.
15120 Redo calculations to avoid overflow.
15121 * keyboard.h: Change prototypes to match the above.
15123 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15125 (current_minor_maps): Check for size calculation overflow.
15126 * keymap.h: Change prototypes to match the above.
15128 * lread.c (read1, init_obarray): Don't update size until alloc done.
15130 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15131 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15133 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15134 Now ptrdiff_t, not int.
15135 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
15136 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
15138 * process.c (Fnetwork_interface_list): Check for overflow
15139 in size calculation.
15141 * region-cache.c (move_cache_gap): Check for size calculation overflow.
15143 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
15144 overflow. Don't bother calling xmalloc when xrealloc will do.
15146 * search.c (Freplace_match): Check for size calculation overflow.
15147 (Fset_match_data): Don't assume list lengths fit in 'int'.
15149 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15150 for command line length. Do not attempt to address one before the
15151 beginning of an array, as that's not portable.
15153 * term.c (max_frame_lines): Remove; unused.
15154 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15156 (encode_terminal_code, calculate_costs): Check for size
15157 calculation overflow.

15159 table lengths and related sizes. Don't update size until alloc
15160 done. Redo calculations to avoid overflow.
15161 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15163 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15164 subtracting pointers.
15165 (gobble_line): Check for overflow more carefully. Don't update size
15168 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
15169 Don't update size until alloc done.
15170 Redo size calculations to avoid overflow.
15171 Check for size calculation overflow.
15172 (main) [DEBUG]: Fix typo in invoking tparam1.

15179 Use ptrdiff_t, not int, for sizes.
15180 (Finternal_make_lisp_face, cache_face):
15181 Check for size calculation overflow.
15182 (cache_face): Treat size calculation overflows as if they were
15183 memory exhaustion (the usual treatment), rather than aborting.
15185 * xfns.c (x_encode_text, x_set_name_internal)
15186 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15187 sizes, since they can exceed INT_MAX in size. Check for size
15188 calculation overflow.
15190 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15191 (xg_select): Check for size calculation overflow.
15192 Don't update size until alloc done.
15194 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15195 as sprintf is limited to int lengths.
15197 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15198 (X_LONG_MIN): New macros.
15199 Use them to make the following changes clearer.
15200 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15201 This change doesn't affect the value now, but it may help remind
15202 future maintainers not to raise the value too much later.
15203 (SELECTION_QUANTUM): Remove, replacing with ...
15204 (selection_quantum): ... new function, which avoids overflow.
15206 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15207 assumption that selection length fits in 'int'.
15208 (x_reply_selection_request, x_handle_selection_request)
15209 (x_get_window_property, receive_incremental_selection)
15210 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15211 (lisp_data_to_selection_data, clean_local_selection_data):

15213 (x_reply_selection_request, x_get_window_property)
15214 (receive_incremental_selection, x_property_data_to_lisp):
15215 Redo calculations to avoid overflow.
15216 (x_reply_selection_request): When sending hint, ceiling it at
15217 X_LONG_MAX rather than relying on wraparound overflow to send
15219 (x_get_window_property, receive_incremental_selection)
15220 (lisp_data_to_selection_data, x_property_data_to_lisp):
15221 Check for size-calculation overflow.

15224 Don't store size until memory allocation succeeds.
15225 (x_get_window_property): Plug memory leak on memory exhaustion.
15226 Don't double-block input; malloc is safe here. Don't assume 2**34
15227 - 4 fits in unsigned long. Add an xassert to check
15228 XGetWindowProperty overflow. Be more careful about overflow
15229 calculations, and distinguish size from memory overflow better.
15230 (receive_incremental_selection): When tracing, don't assume
15231 unsigned int is less than INT_MAX.
15232 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15233 harmful) conversions of unsigned short to int.
15234 (lisp_data_to_selection_data): Don't assume that integers
15235 in the range -65535 through -1 fit in an X unsigned short.
15236 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15237 result parameters unless successful. Rely on cons_to_unsigned
15238 to report problems with elements; the old code wasn't right anyway.
15239 (x_check_property_data): Check for int overflow; we cannot use
15240 a wider type due to X limits.
15241 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15243 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15245 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15246 (x_term_init): Check for size calculation overflow.
15247 (x_color_cells): Don't store size until memory allocation succeeds.
15248 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15249 Don't assume alloca size is less than MAX_ALLOCA.
15250 (x_term_init): Don't assume length fits in int (sprintf is limited
15253 Use ptrdiff_t for composition IDs.

15272 * image.c (xpm_get_color_table_h):
15273 * lisp.h (hash_lookup, hash_put):
15274 * minibuf.c (Ftest_completion):
15275 Use ptrdiff_t for hash table indexes, not int (which is too
15276 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15277 32-bit --with-wide-int hosts).
15279 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15280 Add a FIXME comment about memory leaks.
15281 (syms_of_charset): Don't assume xmalloc returns.

15285 * character.h (CHAR_WIDTH):
15286 * indent.c (MULTIBYTE_BYTES_WIDTH):
15287 Use sanitize_char_width to avoid undefined and/or bad behavior
15288 with outlandish widths.
15289 * character.h (sanitize_tab_width): Rename from sanitize_width,
15290 now that we have two such functions. All uses changed.

15302 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15304 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15305 Remove unreachable code.

15308 * xterm.c: Don't go over XClientMessageEvent limit.
15309 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15310 (x_send_scroll_bar_event): Likewise. Check that the size does not
15311 exceed limits imposed by XClientMessageEvent, as well as the usual
15312 ptrdiff_t and size_t limits.
15314 * keyboard.c: Overflow, signedness and related fixes.
15315 (make_lispy_movement): Use same integer type in forward decl
15316 that is used in the definition.
15317 (read_key_sequence, keyremap_step):
15318 Change bufsize argument back to int, undoing my 2011-03-30 change.
15319 We prefer signed types, and int is wide enough here.
15320 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15321 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15322 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15323 length, not size_t. Use ptrdiff_t for index, not int.
15324 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15325 possibility of integer overflow.
15327 Overflow, signedness and related fixes for images.
15329 * dispextern.h (struct it.stack[0].u.image.image_id)
15330 (struct_it.image_id, struct image.id, struct image_cache.size)

15348 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15349 (lookup_image): Remove unnecessary tests.
15350 (xbm_image_p): Locals are now of int, not EMACS_INT,
15351 since parse_image_check makes sure they fit into int.
15352 (png_load, gif_load, svg_load_image):
15353 Prefer int to unsigned where either will do.
15354 (tiff_handler): New function, combining the cores of the
15355 old tiff_error_handler and tiff_warning_handler.
15356 This function is rewritten to use vsnprintf and thereby avoid
15357 stack buffer overflows. It uses only the features of vsnprintf
15358 that are common to both POSIX and native Microsoft.
15359 (tiff_error_handler, tiff_warning_handler): Use it.
15360 (tiff_load, gif_load, imagemagick_load_image):
15361 Don't assume :index value fits in 'int'.
15362 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15363 (imagemagick_load_image): Check that crop parameters fit into
15364 the integer types that MagickCropImage accepts. Don't assume
15365 Vimagemagick_render_type has a nonnegative value. Don't assume
15366 size_t fits in 'long'.
15367 (gs_load): Use printmax_t to print the widest integers possible.
15368 Check for integer overflow when computing image height and width.
15370 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15372 * xdisp.c (redisplay_window): Don't force window start if point
15373 will be invisible in the resulting window. (Bug#9324)

15377 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15378 the display spec is of the form `(space ...)'.
15379 (handle_display_spec): Return the value returned by
15380 handle_single_display_spec, not just 1 or zero.
15381 (handle_single_display_spec): If the display spec is of the form
15382 `(space ...)', and specifies display in the text area, return 2
15384 (try_cursor_movement): Check for the need to scroll more
15385 accurately, and prefer exact match for point under bidi.
15386 Don't advance `row' beyond the last row of the window.
15388 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15389 into disp_prop; all users changed.
15391 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

15403 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15404 buffers, return left-to-right.
15405 (set_cursor_from_row): Consider candidate row a win if its glyph
15406 represents a newline and point is on that newline. Fixes cursor
15407 positioning on the newline at EOL of R2L text within L2R
15408 paragraph, and vice versa.
15409 (try_cursor_movement): Check continued rows, in addition to
15410 continuation rows. Fixes unwarranted scroll when point enters a
15411 continued line of R2L text within an L2R paragraph, or vice versa.
15412 (cursor_row_p): Consider the case of point being equal to
15413 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15414 from the end of a short line to the beginning of a continued line
15415 of R2L text within L2R paragraph.
15416 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15417 composed characters.

15442 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15443 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15444 candidate is selected by the mouse, and that candidate has a
15445 composed character under the mouse.
15447 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15448 coordinates reported by pos-visible-in-window-p for a composed
15449 character in column zero.
15451 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15453 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15455 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15457 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15458 consider it a hit if to_charpos is anywhere in the range of the
15459 composed buffer positions.
15461 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15463 * image.c (gif_load): Don't assume that each subimage has the same
15464 dimensions as the base image. Handle disposal method that is
15465 "undefined" by the gif spec (Bug#9335).
15467 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15469 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15474 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15475 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15476 from an Org mode buffer to a Speedbar frame.
15478 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15479 a composition, take its buffer position from IT->cmp_it.charpos.
15480 Fixes cursor positioning at the beginning of a line that begins
15481 with a composed character.
15483 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15485 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15486 character bidirectional type, use STRONG_L instead. Fixes crashes
15487 in a buffer produced by `describe-categories'.
15489 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15490 members before the level stack, so they would be saved and
15491 restored when copying iterator state. Fixes incorrect reordering
15492 around TABs covered by display properties.

15520 Fix memory allocation problems in Cygwin build (Bug#9273).
15522 * unexcw.c ( __malloc_initialized): Declare external variable.
15523 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15525 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15527 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

15566 * xdisp.c (move_it_in_display_line_to): Don't invoke
15567 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15568 ppos_it. Fixes vertical cursor motion when line beginning is
15569 covered by an image. (Bug#9296)
15571 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15573 * nsterm.h (ns_run_ascript): Declare.

15580 the event loop. Get status from as_status (Bug#7276).
15582 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15583 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15584 the event loop (Bug#7276).

15597 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
15600 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
15602 * xfaces.c (Qframe_set_background_mode): Now static.
15603 * dispextern.h (Qframe_set_background_mode): Remove decl.
15605 * process.c (Fnetwork_interface_info): Declare local only if needed.
15607 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
15609 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15610 (Fnetwork_interface_list): Allocate in increments of bytes instead
15611 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15612 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15614 (struct ifflag_def): notrailers is smart on OSX.
15615 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15616 Get hardware address with getifaddrs if available.
15618 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15620 * xdisp.c (iterate_out_of_display_property): xassert that
15621 IT->position is set to within IT->object's boundaries. Break from
15622 the loop as soon as EOB is reached; avoids infloops in redisplay
15623 when IT->position is set up wrongly due to some bug.
15624 Set IT->current to match the bidi iterator unconditionally.
15625 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15626 entry. Force push_it to save on the stack the current
15627 buffer/string position, to be restored by pop_it. Fix flags in
15628 the iterator structure wrt the object coming from a display
15629 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15630 properties. (Bug#9284)
15632 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15634 * fontset.c (fontset_get_font_group): Add proper type checks.
15637 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15639 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
15640 and LC_VERSION_MIN_MACOSX.
15641 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
15642 (dump_it) [LC_FUNCTION_STARTS]: Use it.
15644 2011-08-08 Eli Zaretskii <eliz@gnu.org>
15646 * xdisp.c (forward_to_next_line_start): Allow to use the
15647 no-display-properties-and-no-overlays under bidi display.
15648 Set disp_pos in the bidi iterator to avoid searches for display
15649 properties and overlays.
15651 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15653 * editfns.c (Fset_time_zone_rule): Document relationship with the
15656 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
15657 the font entity extracted from the cache (Bug#8109).
15659 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15661 * composite.c (autocmp_chars): Don't reset point. That is done by
15662 restore_point_unwind (Bug#5984).
15664 2011-08-07 Juri Linkov <juri@jurta.org>
15666 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15667 to show the arg `TIME' instead of `TIMEVAL'.
15669 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15671 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15672 display property strides EOL and includes a newline, as in
15673 longlines-mode. (Bug#9254)
15674 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15675 word-wrap under bidirectional display. (Bug#9224)
15677 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15678 is non-zero, even if the data buffer is NULL. Fixes a crash in
15679 vertical-motion with longlines-mode. (Bug#9254)
15681 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15683 * bidi.c <bidi_cache_total_alloc>: Now static.
15684 (bidi_initialize): Initialize bidi_cache_total_alloc.
15686 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15689 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15690 amount allocated this far in `bidi_cache_total_alloc'.
15691 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15692 non-zero, only free the data buffer without restoring the cache
15693 contents. All callers changed.
15695 * dispextern.h (bidi_unshelve_cache): Update prototype.
15697 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15698 (move_it_in_display_line, move_it_to)
15699 (move_it_vertically_backward, move_it_by_lines): Replace the call
15700 to xfree to an equivalent call to bidi_unshelve_cache.
15701 (move_it_in_display_line_to): Fix logic of returning
15702 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15704 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15706 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15707 came from a string character with a `cursor' property. (Bug#9229)
15709 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15711 * Makefile.in (LIB_PTHREAD): New variable.
15712 (LIBES): Add LIB_PTHREAD (Bug#9216).
15714 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15715 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15717 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15719 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15721 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15723 * xterm.c (x_find_topmost_parent): New function.
15724 (x_set_frame_alpha): Find topmost parent window with
15725 x_find_topmost_parent and set the property there also (bug#9181).
15726 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15728 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15730 * callproc.c (Fcall_process): Avoid vfork clobbering
15731 the local vars buffer, coding_systems, current_dir.
15733 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15735 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15737 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15739 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15740 so that it is not optimized away.
15742 * xdisp.c (compute_display_string_pos): Remove unused local.
15744 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15746 Fix slow cursor motion and scrolling in large buffers with
15747 selective display, like Org Mode buffers. (Bug#9218)
15749 * dispextern.h (struct bidi_it): New member disp_prop_p.
15751 * xdisp.c: Remove one-slot cache of display string positions.
15752 (compute_display_string_pos): Accept an additional argument
15753 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15754 for a display string or property. If found, set DISP_PROP_P
15757 * bidi.c (bidi_fetch_char): Accept an additional argument
15758 DISP_PROP_P, and pass it to compute_display_string_pos.
15759 Only handle text covered by a display string if DISP_PROP_P is returned
15760 non-zero. All callers of bidi_fetch_char changed.
15762 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15764 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15766 2010-12-03 Don March <don@ohspite.net>
15768 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15769 last character M-[char] is translated to ESC [char] (bug#7541).
15771 2011-08-02 Kenichi Handa <handa@m17n.org>
15773 * lisp.h (uniprop_table): Extern it.
15775 * chartab.c (uniprop_table): Make it non-static.
15777 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15779 * xdisp.c (forward_to_next_line_start): Accept additional argument
15780 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15782 (reseat_at_next_visible_line_start): Use the bidi iterator state
15783 returned by forward_to_next_line_start to restore the state of
15784 it->bidi_it after backing up to previous newline. (Bug#9212)
15786 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15788 * regex.c (re_comp): Protoize.
15789 (re_exec): Fix return type.
15790 (regexec): Fix type of `ret'. (Bug#9203)
15792 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15794 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15795 This is needed if max-image-size is a floating-point number.
15797 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15799 * print.c (print_object): Print empty symbol as ##.
15801 * lread.c (read1): Read ## as empty symbol.
15803 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15805 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15806 setting frame foreground color (Bug#9175).
15807 (x_set_background_color): Likewise.
15809 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15810 contents (Bug#9176).
15811 (EmacsTooltip -init): Remove bezels and add shadows to
15814 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15815 or scroll bar (Bug#8470).
15817 * nsfont.m (nsfont_open): Remove assignment to voffset and
15818 unnecessary vars hshink, expand, hd, full_height, min_height.
15819 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15821 * nsterm.h (nsfont_info): Remove voffset field.
15823 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15825 Implement strike-through and overline on NextStep (Bug#8863).
15827 * nsfont.m (nsfont_open): Use underline position provided by font,
15828 instead of hard-coded value of 2.
15829 (nsfont_draw): Call ns_draw_text_decoration instead.
15831 * nsterm.h: Add declaration for ns_draw_text_decoration.
15833 * nsterm.m (ns_draw_text_decoration): New function for drawing
15834 underline, overline, and strike-through.
15835 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15836 ns_draw_text_decoration. Change treatment of cursor drawing to
15837 accommodate underlining, etc.
15839 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15841 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15844 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15846 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15847 Without this fix, if a signal arrives just after memory fills up,
15848 'malloc' might be invoked reentrantly.
15850 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15851 In other words, assume that every image size is allowed, on non-X
15852 hosts. This assumption is probably wrong, but it lets Emacs compile.
15854 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15856 * regex.c (re_iswctype): Convert return values to boolean.
15858 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15860 * xdisp.c (compute_display_string_pos): Don't use cached display
15861 string position if the buffer had its restriction changed.
15864 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15866 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15868 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15870 Integer signedness and overflow and related fixes. (Bug#9079)
15872 * bidi.c: Integer size and overflow fixes.
15873 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15874 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15875 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15876 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15877 (bidi_find_other_level_edge):
15878 Use ptrdiff_t instead of EMACS_INT where either will do.
15879 This works better on 32-bit hosts configured --with-wide-int.
15880 (bidi_cache_ensure_space): Check for size-calculation overflow.
15881 Use % rather than repeated addition, for better worst-case speed.
15882 Don't set bidi_cache_size until after xrealloc returns, because it
15884 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15885 (bidi_cache_ensure_space): Also check that the bidi cache size
15886 does not exceed that of the largest Lisp string or buffer. See Eli
15887 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15889 * alloc.c (__malloc_size_t): Remove.
15890 All uses replaced by size_t. See Andreas Schwab's note
15891 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15893 * image.c: Improve checking for integer overflow.
15894 (check_image_size): Assume that f is nonnull, since
15895 it is always nonnull in practice. This is one less thing to
15896 worry about when checking for integer overflow later.
15897 (x_check_image_size): New function, which checks for integer
15898 overflow issues inside X.
15899 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15900 This removes the need for a memory_full check.
15901 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15902 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15903 (xbm_read_bitmap_data): Change locals back to 'int', since
15904 their values must fit in 'int'.
15905 (xpm_load_image, png_load, tiff_load):
15906 Invoke x_create_x_image_and_pixmap earlier,
15907 to avoid much needless work if the image is too large.
15908 (tiff_load): Treat overly large images as if
15909 x_create_x_image_and_pixmap failed, not as malloc failures.
15910 (gs_load): Use x_check_image_size.
15912 * gtkutil.c: Omit integer casts.
15913 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15914 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15916 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15918 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15919 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15920 would wrongly return t on a 64-bit host.
15922 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15923 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15924 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15925 and therefore cause GCC to emit a bogus diagnostic in some cases.
15927 * image.c: Integer signedness and overflow and related fixes.
15928 This is not an exhaustive set of fixes, but it's time to
15929 record what I've got.
15930 (lookup_pixel_color, check_image_size): Remove redundant decls.
15931 (check_image_size): Don't assume that arbitrary EMACS_INT values
15932 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15933 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15934 (tiff_load, imagemagick_load_image):
15935 Check for overflow in size calculations.
15936 (x_create_x_image_and_pixmap): Remove unnecessary test for
15937 xmalloc returning NULL; that can't happen.
15938 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15939 (xpm_color_bucket): Use better integer hashing function.
15940 (xpm_cache_color): Don't possibly over-allocate memory.
15941 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15942 (gif_memory_source):
15943 Use ptrdiff_t, not int or size_t, to record sizes.
15944 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15945 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15946 either works, as we prefer signed integers.
15947 (tiff_read_from_memory, tiff_write_from_memory):
15948 Return tsize_t, not size_t, since that's what the TIFF API wants.
15949 (tiff_read_from_memory): Don't fail simply because the read would
15950 go past EOF; instead, return a short read.
15951 (tiff_load): Omit no-longer-needed casts.
15952 (Fimagemagick_types): Don't assume size fits into 'int'.
15954 Improve hashing quality when configured --with-wide-int.
15955 * fns.c (hash_string): New function, taken from sxhash_string.
15956 Do not discard information about ASCII character case; this
15957 discarding is no longer needed.
15958 (sxhash-string): Use it. Change sig to match it. Caller changed.
15959 * lisp.h: Declare it.
15960 * lread.c (hash_string): Remove, since we now use fns.c's version.
15961 The fns.c version returns a wider integer if --with-wide-int is
15962 specified, so this should help the quality of the hashing a bit.
15964 * emacs.c: Integer overflow minor fix.
15965 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15966 Define only if GNU_LINUX.
15967 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15969 * dispnew.c: Integer signedness and overflow fixes.
15970 Remove unnecessary forward decls, that were a maintenance hassle.
15971 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15973 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15974 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15975 (prepare_desired_row, line_draw_cost):
15976 Use int, not unsigned, where either works.
15977 (save_current_matrix, restore_current_matrix):
15978 Use ptrdiff_t, not size_t, where either works.
15979 (init_display): Check for overflow more accurately, and without
15980 relying on undefined behavior.
15982 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15983 Remove, replacing with the new symbols in lisp.h. All uses changed.
15984 * fileio.c (make_temp_name):
15985 * filelock.c (lock_file_1, lock_file):
15986 * xdisp.c (message_dolog):
15987 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15988 Use pMd etc. instead.
15989 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15990 replacing the pWIDE etc. symbols removed from editfns.c.
15992 * keyboard.h (num_input_events): Now uintmax_t.
15993 This is (very slightly) less likely to mess up due to wraparound.
15996 * buffer.c: Integer signedness fixes.
15997 (alloc_buffer_text, enlarge_buffer_text):
15998 Use ptrdiff_t rather than size_t when either will do, as we prefer
16001 * alloc.c: Integer signedness and overflow fixes.
16002 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16003 (__malloc_size_t): Default to size_t, not to int.
16004 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16005 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16006 Prefer ptrdiff_t to size_t when either would do, as we prefer
16008 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16009 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16010 Now const. Initialize with values that are in range even if char
16012 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16013 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16014 These functions do the right thing with sizes > 2**32.
16015 (check_depth): Now ptrdiff_t, not int.
16016 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16017 Adjust to new way of storing sizes. Check for size overflow bugs
16019 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16020 slightly wrong anyway, as it missed one instance of
16021 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16022 (refill_memory_reserve): Omit needless cast to size_t.
16023 (mark_object_loop_halt): Mark as externally visible.
16025 * xselect.c: Integer signedness and overflow fixes.
16026 (Fx_register_dnd_atom, x_handle_dnd_message):
16027 Use ptrdiff_t, not size_t, since we prefer signed.
16028 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16029 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16030 x_dnd_atoms_size and x_dnd_atoms_length.
16032 * doprnt.c: Prefer signed to unsigned when either works.
16034 * doprnt.c (doprnt):
16036 * xdisp.c (vmessage):
16037 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16038 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16039 prefer signed arithmetic to avoid comparison confusion.
16040 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16041 but is a bit tricky.
16043 Assume freestanding C89 headers, string.h, stdlib.h.
16044 * data.c, doprnt.c, floatfns.c, print.c:
16045 Include float.h unconditionally.
16046 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16047 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16048 * regex.c: Likewise for stddef.h, string.h.
16049 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16050 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16051 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16052 (STDC_HEADERS): Remove obsolete defines.
16053 * sysdep.c: Include limits.h unconditionally.
16055 Assume support for memcmp, memcpy, memmove, memset.
16056 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16057 * regex.c (memcmp, memcpy):
16058 Remove; we assume C89 now.
16060 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16061 (__malloc_safe_bcopy): Remove; no longer needed.
16063 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16064 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16065 well either way, and we prefer signed to unsigned.
16067 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16069 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16070 closes the connection while we're reading (bug#9182).
16072 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16074 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16075 are specified (Bug#9168).
16077 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16079 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16080 Found by GCC static checking and --with-wide-int on a 32-bit host.
16082 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16084 * xdisp.c (compute_display_string_pos): Fix logic of caching
16085 previous display string position. Initialize cached_prev_pos to
16086 -1. Fixes slow-down at the beginning of a buffer.
16088 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16090 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16091 for attrs[LFACE_FONTSET_INDEX].
16093 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16095 * xml.c (parse_region): Remove unused local
16096 that was recently introduced.
16098 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16100 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16101 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16103 * xdisp.c (move_it_in_display_line_to): Record the best matching
16104 position for TO_CHARPOS while scanning the line, and restore it on
16105 exit if none of the characters scanned was an exact match.
16106 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16107 when exact match is impossible due to invisible text, and the
16108 lines are truncated.
16110 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16112 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16115 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16117 Fix a significant slow-down of cursor motion with C-n, C-p,
16118 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16119 auto-repeat under bidi redisplay in fontified buffers.
16120 * xdisp.c (compute_stop_pos_backwards): New function.
16121 (next_element_from_buffer): Call compute_stop_pos_backwards to
16122 find a suitable prev_stop when we find ourselves before
16124 (reseat): Don't look for prev_stop, as that could mean a very long
16126 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16127 <cached_disp_overlay_modiff>: Cache for last found display string
16129 (compute_display_string_pos): Return the cached position if asked
16130 about the same buffer in the same area of character positions, and
16131 the buffer wasn't changed since the time the display string
16132 position was cached.
16134 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16136 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16137 is an integer, which is important for empty lines. (Bug#9149)
16139 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16141 * frame.c (Fmodify_frame_parameters): In tty case, update the
16142 default face if necessary (Bug#4238).
16144 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16146 * editfns.c (Fstring_to_char): No need to explain what a character
16147 is in the docstring (Bug#6576).
16149 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16151 * xml.c (parse_region): Make sure we always return a tree.
16153 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16155 * xml.c (parse_region): If a document contains only comments,
16158 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16160 * xml.c (make_dom): Return comments, too.
16162 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16165 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16166 and the surrounding thread.
16167 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16168 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16169 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16171 * s/openbsd.h (BROKEN_SIGIO): Define.
16172 * unexelf.c (unexec) [__OpenBSD__]:
16173 Don't update the .mdebug section of the Alpha COFF symbol table.
16175 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16177 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16180 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16182 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16183 This fixes some race conditions on the permissions of any newly
16186 * alloc.c (valid_pointer_p): Use pipe, not open.
16187 This fixes some permissions issues when debugging.
16189 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16190 If fchown fails to set both uid and gid, try to set just gid,
16191 as that is sometimes allowed. Adjust the file's mode to eliminate
16192 setuid or setgid bits that are inappropriate if fchown fails.
16194 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16196 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16197 to compare Lisp_Objects.
16198 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16199 global_gnutls_log_level, don't mistake it for a Lisp_Object.

16202 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16204 * lread.c (read_integer): Unread even EOF character.
16205 (read1): Likewise. Properly record start position of symbol.
16207 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16208 symbol character follows.
16210 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16212 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16213 This works around a problem with the previous change to Fcopy_file.
16214 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16215 and without this change, GCC might complain about discarding
16216 fchown's return value.
16218 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16220 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16222 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16224 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16226 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16228 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16229 it's used from the C level.
16231 * process.c: Use the same condition for POLL_FOR_INPUT in both
16232 keyboard.c and process.c (bug#1858).
16234 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16236 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16237 (Fgnutls_boot): Use it.
16239 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16241 * doc.c (Fsubstitute_command_keys): Revert last change.
16243 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16245 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16246 quotes the next character, and doesn't affect other longer
16247 sequences (bug#8935).
16249 * lread.c (syms_of_lread): Clarify that is isn't only
16250 `eval-buffer' and `eval-defun' that's affected by
16251 `lexical-binding' (bug#8460).
16253 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16255 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16256 bidi redisplay when a line includes both an image and is truncated.
16258 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16260 Fix minor problems found by static checking.
16261 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16262 (elsz): Now a signed constant, not a size_t var. We prefer signed
16263 types to unsigned, to avoid integer comparison confusion. Without
16264 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16265 "cannot optimize loop, the loop counter may overflow", a symptom
16267 * indent.c (Fvertical_motion): Mark locals as initialized.
16268 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16270 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16272 * search.c (Fre_search_backward): Mention `case-fold-search' in
16273 all the re_search_* functions (bug#8138).

16288 bidi_it->string.schars.
16289 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to

16293 buffer position was specified. Initialize paragraph_embedding to
16295 (reseat_to_string): Initialize the bidi iterator.
16296 (display_string): If we need to ignore text properties of
16297 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16298 original value of -1 will not work with bidi.)
16299 (compute_display_string_pos): First arg is now struct
16300 `text_pos *'; all callers changed. Support display properties on
16302 (compute_display_string_end): Support display properties on Lisp
16304 (init_iterator, reseat_1, reseat_to_string): Initialize the
16305 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16306 when iterating on a string not from display properties).
16307 (compute_display_string_pos, compute_display_string_end):
16308 Fix calculation of the object to scan. Fixes an error when using
16310 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16311 base_level_stop; instead, set base_level_stop to BEGV.
16312 Fixes crashes in vertical-motion.
16313 (next_element_from_buffer): Improve commentary for when
16314 the iterator is before prev_stop.
16315 (init_iterator): Initialize bidi_p from the default value of
16316 bidi-display-reordering, not from buffer-local value. Use the
16317 buffer-local value only if initializing for buffer iteration.
16318 (handle_invisible_prop): Support invisible properties on strings
16319 that are being bidi-reordered.
16320 (set_iterator_to_next): Support bidi reordering of C strings and
16322 (next_element_from_string): Support bidi reordering of Lisp

16326 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16327 (init_iterator): Don't initialize it->bidi_p for strings
16329 (reseat_to_string): Initialize it->bidi_p for strings here.
16330 (next_element_from_string, next_element_from_c_string)
16331 (next_element_from_buffer): Add xassert's for correspondence

16336 character that is not the first one in the visual order.
16337 (get_visually_first_element): New function, refactored from common
16338 parts of next_element_from_buffer, next_element_from_string, and
16339 next_element_from_c_string.
16340 (tool_bar_lines_needed, redisplay_tool_bar)
16341 (display_menu_bar): Force left-to-right direction. Add a FIXME
16342 comment for making that be controlled by a user option.
16343 (push_it, pop_it): Save and restore the state of the
16344 bidi iterator. Save and restore the bidi_p flag.
16345 (pop_it): Iterate out of display property for string iteration as

16348 (handle_single_display_spec): Set up it->bidi_it for iteration
16349 over a display string, and call bidi_init_it.
16350 (handle_single_display_spec, next_overlay_string)
16351 (get_overlay_strings_1, push_display_prop): Set up the bidi
16352 iterator for displaying display or overlay strings.
16353 (forward_to_next_line_start): Don't use the shortcut if
16355 (back_to_previous_visible_line_start): If handle_display_prop
16356 pushed the iterator stack, restore the internal state of the bidi
16357 iterator by calling bidi_pop_it same number of times.
16358 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16359 and we are bidi-iterating, don't decrement the iterator position;
16360 instead, set the first_elt flag in the bidi iterator, to produce
16362 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16363 (push_display_prop): xassert that we are iterating a buffer.
16364 (push_it, pop_it): Save and restore paragraph_embedding member.
16365 (handle_single_display_spec, next_overlay_string)
16366 (get_overlay_strings_1, reseat_1, reseat_to_string)
16367 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16368 correctly. Don't assume unibyte strings are not bidi-reordered.
16369 (compute_display_string_pos)
16370 (compute_display_string_end): Fix handling the case of C string.
16371 (push_it, pop_it): Save and restore from_disp_prop_p.

16376 popping after iteration over a string that came from a display
16377 property. Fix a typo in popping stretch info. Add an assertion
16378 for verifying that the iterator position is in sync with the bidi
16380 (handle_single_display_spec, get_overlay_strings_1)

16393 (move_it_to, move_it_vertically_backward, move_it_by_lines)
16394 (try_scrolling, redisplay_window, display_line): Use them when
16395 saving a temporary copy of the iterator and restoring it back.
16396 (back_to_previous_visible_line_start, reseat_1)

16398 (move_it_in_display_line_to): If iterator ended up at
16399 EOL, but we never saw any buffer positions smaller than
16400 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16401 motion in bidi-reordered lines.

16403 immediately before the call to set_iterator_to_next. Fixes cursor
16404 motion in bidi-reordered lines with stretch glyphs and strings
16405 displayed in margins. (Bug#8133) (Bug#8867)
16406 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16408 (pos_visible_p): Support positions in bidi-reordered lines.
16409 Save and restore bidi cache.
16411 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16412 (bidi_paragraph_info): Delete unused struct.
16413 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
16414 (bidi_cache_start): New variable.

16430 Support iteration over a string.
16431 (bidi_set_sor_type, bidi_resolve_explicit_1)
16432 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16433 can now be zero (for strings); special values 0 and -1 were
16434 changed to -1 and -2, respectively.
16435 (bidi_char_at_pos): New function.
16436 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16522 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16524 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16525 The old code sometimes used this field without initializing it.
16527 * alloc.c (gc_sweep): Don't read past end of array.
16528 In theory, the old code could also have corrupted Emacs internals,
16529 though it'd be very unlikely.

16792 (clone_per_buffer_values): Don't assume that

16794 This isn't true in general, and it's particularly not true
16795 if Emacs is configured with --with-wide-int.
16796 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

16833 Random fixes. E.g., (random) never returned negative values.
16834 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16835 subseconds part to the entropy, as that's a bit more random.
16836 Prefer signed to unsigned, since the signedness doesn't matter and
16837 in general we prefer signed. When given a limit, use a
16838 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16839 latter isn't right if USE_2_TAGS_FOR_INTS.
16840 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16841 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16853 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16854 This is more efficient than Ffile_directory_p and avoids a minor race.
16856 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16858 * buffer.c (Foverlay_put): Say what the return value is
16861 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16862 is a directory before asking whether to use the file name
16864 (barf_or_query_if_file_exists): Make the "File is a directory"
16865 error be more correct.
16867 * fns.c (Frequire): Remove the mention of the .gz files, since
16868 that's installation-specific, but keep the mention of

16881 Qgnutls_bootprop_verify_error (which is no longer used).
16883 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16884 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16885 Also (re)move comments that are misplaced or no longer relevant.

16914 * lread.c (syms_of_lread): Mention single symbols defined by
16915 `defvar' or `defconst' (bug#7154).
16917 * fns.c (Frequire): Mention .el.gz files (bug#7314).
16918 (Frequire): Mention get-load-suffixes.

16986 * eval.c (struct backtrace): Simplify and port the data structure.
16987 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16988 signed bit field, as this assumption is not portable and it makes
16989 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16990 "char debug_on_exit : 1" as this is not portable either; instead,
16991 use the portable "unsigned int debug_on_exit : 1". Remove unused
16992 member evalargs. Remove obsolete comments about cc bombing out.

17161 (PRINTPREPARE, printchar, strout):
17162 Don't set size unless allocation succeeds.
17164 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17165 for sizes. Check for string overflow more accurately.

17176 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17178 * lread.c: Integer overflow fixes.
17179 (read_integer): Radix is now EMACS_INT, not int,
17180 to improve quality of diagnostics for out-of-range radices.
17181 Calculate buffer size correctly for out-of-range radices.
17182 (read1): Check for integer overflow in radices, and in
17183 read-circle numbers.
17184 (read_escape): Avoid int overflow.
17185 (Fload, openp, read_buffer_size, read1)
17186 (substitute_object_recurse, read_vector, read_list, map_obarray):

17202 2011-06-22 Leo Liu <sdl.web@gmail.com>
17204 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17205 Move to minibuffer.el.
17207 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17209 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17210 The following patches are for when GLYPH_DEBUG && !XASSERT.
17211 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17212 * dispnew.c (flush_stdout):
17213 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17214 Mark as externally visible.
17215 * dispnew.c (check_window_matrix_pointers): Now static.

17224 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17226 (debug_method_add): Use va_list and vsprintf rather than relying
17227 on undefined behavior with wrong number of arguments.
17228 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17229 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17230 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17231 since we're not interested in debugging glyphs with old libraries.
17232 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17233 GCC 4.6.0's static checking.
17235 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

17270 (overlays_at, overlays_in): Check for size-calculation overflow.
17272 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17274 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17275 (x_session_initialize): Do not assume string length fits in int.
17277 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17278 This is unlikely, but can occur if DPI is outlandish.
17280 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17281 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

17323 Don't assume pid_t and time_t fit in unsigned long.
17324 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17325 (current_lock_owner): Prefer signed type for sizes.
17326 Use memcpy, not strncpy, where memcpy is what is really wanted.
17327 Don't assume (via atoi) that time_t and pid_t fit in int.
17328 Check for time_t and/or pid_t out of range, e.g., via a network share.
17329 Don't alloca where an auto var works fine.
17331 * fileio.c: Fix some integer overflow issues.

17356 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17358 * lread.c (invalid_syntax): Omit length argument.
17359 All uses changed. This doesn't fix a bug, but it simplifies the
17360 code away from its former Hollerith-constant appearance, and it's
17361 one less 'int' to worry about when looking at integer-overflow issues.
17362 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17364 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17365 This didn't break anything, but it didn't help either.
17366 It's confusing to put a bogus integer in a place where the actual
17367 value does not matter.
17368 (LIST_END_P): Remove unused macro and its bogus comment.
17369 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17371 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17372 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17374 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17375 We prefer signed types, and the value cannot exceed the EMACS_INT
17376 range anyway (because otherwise the length would not be representable).
17377 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17378 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17379 This avoids a GCC warning when WIDE_EMACS_INT.
17381 * indent.c (sane_tab_width): New function.
17382 (current_column, scan_for_column, Findent_to, position_indentation)
17383 (compute_motion): Use it. This is just for clarity.
17384 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17386 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17388 * lisp.h (lint_assume): New macro.
17389 * composite.c (composition_gstring_put_cache):
17390 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17392 * editfns.c, insdel.c:
17393 Omit unnecessary forward decls, to simplify future changes.
17395 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17397 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17399 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17400 Use much-faster test for byte-length change.
17401 Don't assume string byte-length fits in 'int'.
17402 Check that character arg fits in 'int'.
17403 (mapcar1): Declare byte as byte, for clarity.
17405 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17407 * fns.c (concat): Catch string overflow earlier.
17408 Do not rely on integer wraparound.
17410 * dispextern.h (struct it.overlay_strings_charpos)
17411 (struct it.selective): Now EMACS_INT, not int.
17412 * xdisp.c (forward_to_next_line_start)
17413 (back_to_previous_visible_line_start)
17414 (reseat_at_next_visible_line_start, next_element_from_buffer):
17415 Don't arbitrarily truncate the value of 'selective' to int.
17417 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17419 * composite.c: Don't truncate sizes to 'int'.
17420 (composition_gstring_p, composition_reseat_it)
17421 (composition_adjust_point): Use EMACS_INT, not int.
17422 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17423 not EMACS_UINT, for indexes.
17425 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17427 * buffer.c: Include <verify.h>.
17428 (struct sortvec.priority, struct sortstr.priority):
17429 Now EMACS_INT, not int.
17430 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17431 (struct sortstr.size, record_overlay_string)
17432 (struct sortstrlist.size, struct sortlist.used):
17433 Don't truncate size to int.
17434 (record_overlay_string): Check for size-calculation overflow.
17435 (init_buffer_once): Check at compile-time, not run-time.
17437 2011-06-22 Jim Meyering <meyering@redhat.com>
17439 Don't leak an XBM-image-sized buffer
17440 * image.c (xbm_load): Free the image buffer after using it.
17442 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17445 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17446 that Sun C diagnosed.
17447 * fns.c (secure_hash): Fix pointer signedness issue.
17448 * intervals.c (static_offset_intervals): New function.
17449 (offset_intervals): Use it.
17451 2011-06-21 Leo Liu <sdl.web@gmail.com>
17454 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17457 * fns.c (secure_hash): Rename from crypto_hash_function and change
17458 the first arg to accept symbols.
17459 (Fsecure_hash): New primitive.
17460 (syms_of_fns): New symbols.
17462 2011-06-20 Deniz Dogan <deniz@dogan.se>
17464 * process.c (Fset_process_buffer): Clarify return value in
17467 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17469 * dispnew.c (add_window_display_history): Use BVAR.
17471 * xdisp.c (debug_method_add): Use BVAR.
17472 (check_window_end, dump_glyph_matrix, dump_glyph)
17473 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17475 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17478 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17479 check till after the cache is created in init_frame_faces.
17481 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17483 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17485 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17487 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17488 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17489 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17491 Improve buffer-overflow checking (Bug#8873).
17492 * fileio.c (Finsert_file_contents):
17493 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17494 Remove the old (too-loose) buffer overflow checks.
17495 They weren't needed, since make_gap checks for buffer overflow.
17496 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17497 The old code merely checked for Emacs fixnum overflow, and relied
17498 on undefined (wraparound) behavior. The new code avoids undefined
17499 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17501 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17502 Tune. Don't use wider integers than needed. Don't use alloca.
17503 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17505 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17507 * insdel.c, lisp.h (buffer_overflow): New function.
17508 (insert_from_buffer_1, replace_range, replace_range_2):
17509 * insdel.c (make_gap_larger):
17510 * editfns.c (Finsert_char):
17511 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17513 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17515 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17517 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17519 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17520 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17522 * fileio.c: Don't assume EMACS_INT fits in off_t.
17523 (emacs_lseek): New static function.
17524 (Finsert_file_contents, Fwrite_region): Use it.
17525 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17527 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17529 * fns.c: Don't overflow int when computing a list length.
17530 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17531 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17532 truncation on 64-bit hosts. Check for QUIT every
17533 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17534 faster and is responsive enough.
17535 (Flength): Report an error instead of overflowing an integer.
17536 (Fsafe_length): Return a float if the value is not representable
17537 as a fixnum. This shouldn't happen except in contrived situations.
17538 (Fnthcdr, Fsort): Don't assume list length fits in int.
17539 (Fcopy_sequence): Don't assume vector length fits in int.
17541 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17542 (header_size, word_size): New constants.
17543 (allocate_vectorlike): Don't check size overflow here.
17544 (allocate_vector): Check it here instead, since this is the only
17545 caller of allocate_vectorlike that could cause overflow.
17546 Check that the new vector's length is representable as a fixnum.
17548 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17549 The previous code was bogus. For example, next_almost_prime (32)
17550 returned 39, which is undesirable as it is a multiple of 3; and
17551 next_almost_prime (24) returned 25, which is a multiple of 5 so
17552 why was the code bothering to check for multiples of 7?
17554 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17556 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17558 Variadic C functions now count arguments with ptrdiff_t.
17559 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17560 Back then I didn't know that the Emacs coding style prefers signed int.
17561 Also, in the meantime I found a few more instances where arguments
17562 were being counted with int, which may truncate counts on 64-bit
17563 machines, or EMACS_INT, which may be unnecessarily wide.
17564 * lisp.h (struct Lisp_Subr.function.aMANY)
17565 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17566 Arg counts are now ptrdiff_t, not size_t.
17567 All variadic functions and their callers changed accordingly.
17568 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17569 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17570 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17571 * callint.c (Fcall_interactively): Check arg count for overflow,
17572 to avoid potential buffer overrun. Use signed char, not 'int',
17573 for 'varies' array, so that we needn't bother to check its size
17574 calculation for overflow.
17575 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17576 * eval.c (apply_lambda):
17577 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17578 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17579 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17581 * callint.c (Fcall_interactively): Don't use index var as event count.
17583 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17584 * mem-limits.h (SIZE): Remove; no longer used.
17586 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17588 Remove unnecessary casts.
17589 * xterm.c (x_term_init):
17590 * xfns.c (x_set_border_pixel):
17591 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17592 These aren't needed now that we assume ANSI C.
17594 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17595 It's more likely to cause problems (due to unsigned overflow)
17598 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17600 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17602 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17604 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17606 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17608 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17610 GLYPH_CODE_FACE returns EMACS_INT, not int.
17611 * dispextern.h (merge_faces):
17612 * xfaces.c (merge_faces):
17613 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17614 Don't assume EMACS_INT fits in int.
17616 * character.h (CHAR_VALID_P): Remove unused parameter.
17617 * fontset.c, lisp.h, xdisp.c: All uses changed.
17619 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17621 * fns.c (concat): Minor tuning based on overflow analysis.
17622 This doesn't fix any bugs. Use int to hold character, instead
17623 of constantly refetching from Emacs object. Use XFASTINT, not
17624 XINT, for value known to be a character. Don't bother comparing
17625 a single byte to 0400, as it's always less.
17627 * floatfns.c (Fexpt):
17628 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17630 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17633 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17635 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17636 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17637 incorrectly succeed when S was a string, because 4294967386 was
17638 truncated before it was used.
17640 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17641 Otherwise, an out-of-range integer could cause undefined behavior
17644 * composite.c: Use int, not EMACS_INT, for characters.
17645 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17646 EMACS_INT, for values that are known to be in character range.
17647 This doesn't fix any bugs but is the usual style inside Emacs and
17648 may generate better code on 32-bit machines.
17650 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17651 This is for reasons similar to the recent CHAR_STRING fix.
17652 * charset.c (Fencode_char): Check that character arg is actually
17653 a character. Pass an int to ENCODE_CHAR.
17654 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17655 wider than 'int', as a compile-time check to prevent future regressions
17658 * character.c (char_string): Remove unnecessary casts.
17660 Make sure a 64-bit char is never passed to CHAR_STRING.
17661 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17662 by silently ignoring the top 32 bits, allowing some values
17663 that were far too large to be valid characters.
17664 * character.h: Include <verify.h>.
17665 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17666 arguments are no wider than unsigned, as a compile-time check
17667 to prevent future regressions in this area.
17669 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17670 (Fsubst_char_in_region):
17672 * xdisp.c (decode_mode_spec_coding):
17673 Adjust to CHAR_STRING's new requirement.
17674 * editfns.c (Finsert_char, Fsubst_char_in_region):
17675 * fns.c (concat): Check that character args are actually
17676 characters. Without this test, these functions did the wrong
17677 thing with wildly out-of-range values on 64-bit hosts.
17679 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17680 These casts should not be needed on 32-bit hosts, either.
17681 * keyboard.c (read_char):
17682 * lread.c (Fload): Remove casts to unsigned.
17684 * lisp.h (UNSIGNED_CMP): New macro.
17685 This fixes comparison bugs on 64-bit hosts.
17686 (ASCII_CHAR_P): Use it.
17687 * casefiddle.c (casify_object):
17688 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17689 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17690 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17691 * dispextern.h (FACE_FROM_ID):
17692 * keyboard.c (read_char): Use UNSIGNED_CMP.
17694 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17695 not to EMACS_INT, to avoid GCC warning.
17697 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17699 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17700 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17701 isn't needed on 32-bit machines.
17703 * buffer.c (Fgenerate_new_buffer_name):
17704 Use EMACS_INT for count, not int.
17705 (advance_to_char_boundary): Return EMACS_INT, not int.
17707 * data.c (Qcompiled_function): Now static.
17709 * window.c (window_body_lines): Now static.
17711 * image.c (gif_load): Rename local to avoid shadowing.
17713 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17714 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17715 * alloc.c (make_save_value): Integer argument is now of type
17716 ptrdiff_t, not int.
17717 (mark_object): Use ptrdiff_t, not int.
17718 * lisp.h (pD): New macro.
17719 * print.c (print_object): Use it.
17721 * alloc.c: Use EMACS_INT, not int, to count objects.
17722 (total_conses, total_markers, total_symbols, total_vector_size)
17723 (total_free_conses, total_free_markers, total_free_symbols)
17724 (total_free_floats, total_floats, total_free_intervals)
17725 (total_intervals, total_strings, total_free_strings):
17726 Now EMACS_INT, not int. All uses changed.
17727 (Fgarbage_collect): Compute overall total using a double, so that
17728 integer overflow is less likely to be a problem. Check for overflow
17729 when converting back to an integer.
17730 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17731 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17732 These were 'int' variables that could overflow on 64-bit hosts;
17733 they were never used, so remove them instead of repairing them.
17734 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17735 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17736 Previously, this ceilinged at INT_MAX, but that doesn't work on
17738 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17740 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17741 (allocate_vectorlike): Check for ptrdiff_t overflow.
17742 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17743 when a (possibly-narrower) signed value would do just as well.
17744 We prefer using signed arithmetic, to avoid comparison confusion.
17746 * alloc.c: Catch some string size overflows that we were missing.
17747 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17748 for convenience in STRING_BYTES_MAX.
17749 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17750 The definition here is exact; the one in lisp.h was approximate.
17751 (allocate_string_data): Check for string overflow. This catches
17752 some instances we weren't catching before. Also, it catches
17753 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17754 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17755 and ptrdiff_t and EMACS_INT are both 64 bits.
17757 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17758 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17759 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17761 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17763 * alloc.c (Fmake_string): Check for out-of-range init.
17765 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17767 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17769 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17771 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17772 xg_get_default_scrollbar_width.
17774 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17775 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17776 (style_changed_cb): Call update_theme_scrollbar_width and call
17777 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17778 all frames (Bug#8505).
17779 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17780 Call gtk_window_set_resizable if HAVE_GTK3.
17781 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17782 and height if HAVE_GTK3 (Bug#8505).
17783 (scroll_bar_width_for_theme): New variable.
17784 (update_theme_scrollbar_width): New function.
17785 (xg_get_default_scrollbar_width): Move code to
17786 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17787 (xg_initialize): Call update_theme_scrollbar_width.
17789 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17791 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17793 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17795 * frame.c (make_frame): Call other_buffer_safely instead of
17798 * window.c (temp_output_buffer_show): Call display_buffer with
17799 second argument Vtemp_buffer_show_specifiers and reset latter
17800 immediately after the call.

18253 or arbitrary window as argument. Update doc-strings.
18254 (Fminibuffer_window): Move up in code.
18255 (Fwindow_minibuffer_p): Move up in code and simplify.
18256 (Fset_frame_selected_window): Move here from frame.c.
18258 (Fselected_window, select_window, Fselect_window): Move up in
18259 code. Minor doc-string fixes.
18261 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18263 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18264 Do not assume that spare memory exists; that assumption is valid
18265 only if SYSTEM_MALLOC.
18266 (LARGE_REQUEST): New macro, so that the issue of large requests
18267 is separated from the issue of spare memory.
18269 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
18271 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

18295 (x_clipboard_manager_save): Add return value.
18296 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
18297 New error handlers.
18298 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18299 Obey Vx_select_enable_clipboard_manager. Catch errors in
18300 x_clipboard_manager_save (Bug#8779).
18301 (Vx_select_enable_clipboard_manager): New variable.
18302 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18304 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18306 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18308 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18310 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18311 in the current matrix if keep_current_p is non-zero.

18315 * bidi.c (bidi_level_of_next_char): Fix last change.
18317 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18319 Support bidi reordering of text covered by display properties.
18321 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18322 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18323 (bidi_cache_search, bidi_cache_iterator_state)
18324 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18325 (bidi_level_of_next_char, bidi_move_to_visually_next):
18326 Support character positions inside a run of characters covered by a
18328 (bidi_paragraph_init, bidi_resolve_explicit_1)
18329 (bidi_level_of_next_char): Call bidi_fetch_char and
18330 bidi_fetch_char_advance instead of FETCH_CHAR and
18331 FETCH_CHAR_ADVANCE.
18332 (bidi_init_it): Initialize new members.
18333 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18335 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18336 instead of using explicit *_CHAR codes.
18337 (bidi_resolve_explicit, bidi_resolve_weak):
18338 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18339 bidirectional text is supported only in multibyte buffers.
18340 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18341 it to initialize the frame_window_p member of struct bidi_it.
18342 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18343 (bidi_resolve_explicit, bidi_resolve_weak)

18345 bidi_it->nchars is non-positive.
18346 (bidi_level_of_next_char): Don't try to lookup the cache for the
18347 next/previous character if nothing is cached there yet, or if we
18348 were just reseat()'ed to a new position.
18350 * xdisp.c (set_cursor_from_row): Set start and stop points
18351 according to the row's direction when priming the loop that looks
18352 for the glyph on which to display cursor.
18353 (single_display_spec_intangible_p): Function deleted.
18354 (display_prop_intangible_p): Reimplement to call
18355 handle_display_spec instead of single_display_spec_intangible_p.
18356 Accept 3 additional arguments needed by handle_display_spec.
18357 This fixes incorrect cursor motion across display property with complex
18358 values: lists, `(when COND...)' forms, etc.
18359 (single_display_spec_string_p): Support property values that are
18360 lists with the argument STRING its top-level element.
18361 (display_prop_string_p): Fix the condition for processing a
18362 property that is a list to be consistent with handle_display_spec.
18363 (handle_display_spec): New function, refactored from the
18364 last portion of handle_display_prop.
18365 (compute_display_string_pos): Accept additional argument
18366 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18367 value of a `display' property is a "replacing spec".
18368 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18369 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18370 the display property, but just return a value indicating whether
18371 the display property will replace the characters it covers.
18372 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18373 frame_window_p members of struct bidi_it.
18374 (compute_display_string_pos, compute_display_string_end):
18376 (push_it): Accept second argument POSITION, where pop_it should
18377 jump to continue iteration.
18378 (reseat_1): Initialize bidi_it.disp_pos.
18380 * keyboard.c (adjust_point_for_property): Adjust the call to
18381 display_prop_intangible_p to its new signature.
18383 * dispextern.h (struct bidi_it): New member frame_window_p.
18384 (bidi_init_it): Update prototypes.
18385 (display_prop_intangible_p): Update prototype.
18386 (compute_display_string_pos, compute_display_string_end):
18387 Declare prototypes.
18388 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18391 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18393 Malloc failure behavior now depends on size of allocation.
18394 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18395 * lisp.h: Change signatures accordingly.
18396 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18397 All callers changed. (Bug#8762)
18399 * gnutls.c: Use Emacs's memory allocators.
18400 Without this change, the gnutls library would invoke malloc etc.
18401 directly, which causes problems on non-SYNC_INPUT hosts, and which
18402 runs afoul of improving memory_full behavior. (Bug#8761)
18403 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18404 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18405 xfree instead of the default malloc, realloc, free.
18406 (Fgnutls_boot): No need to check for memory allocation failure,
18407 since xmalloc does that for us.
18409 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18410 * category.c (hash_get_category_set):
18411 * ccl.c (ccl_driver):
18412 * charset.c (Fdefine_charset_internal):
18413 * charset.h (struct charset.hash_index):

18419 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
18420 (hashfn_equal, hashfn_user_defined, make_hash_table)

18422 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18423 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18424 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18425 * image.c (make_image, search_image_cache, lookup_image)
18426 (xpm_put_color_table_h):
18427 * lisp.h (struct Lisp_Hash_Table):
18428 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18429 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18430 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18431 * alloc.c (allocate_vectorlike):
18432 Check for overflow in vector size calculations.
18433 * ccl.c (ccl_driver):
18434 Check for overflow when converting EMACS_INT to int.
18435 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18436 need to be updated by these changes.
18437 * fns.c (make_hash_table, maybe_resize_hash_table):
18438 Check for integer overflow with large hash tables.
18439 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18440 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18441 (SXHASH_REDUCE): New macro.
18442 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18443 Use it instead of discarding useful hash info with large hash values.
18444 (sxhash_float): New function.
18445 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18446 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18447 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18448 Rewrite to use FIXNUM_BITS, as this simplifies things.
18449 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18450 Adjust signatures to match updated version of code.
18451 (consing_since_gc): Now EMACS_INT, since a single hash table can
18452 use more than INT_MAX bytes.
18454 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18456 Make it possible to build with GCC-4.6+ -O2 -flto.
18458 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18460 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18462 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18463 Call minibuffer-inactive-mode.
18465 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18467 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18468 Update dependencies.
18470 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18472 * data.c (init_data): Remove code for UTS, this system is not
18475 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18477 Don't force ./temacs to start in terminal mode.
18479 * frame.c (make_initial_frame): Initialize faces in all cases, not
18480 only when CANNOT_DUMP is defined.
18481 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18483 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18485 * dispnew.c (add_window_display_history): Use const for the string
18486 pointer. Remove declaration, not needed.
18488 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18490 Use 'inline', not 'INLINE'.
18491 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18492 * alloc.c, fontset.c (INLINE): Remove.
18493 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18494 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18495 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18496 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18497 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18499 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18501 Make it possible to run ./temacs.
18503 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18504 syms_of_callproc does the same thing. Remove test for
18505 "initialized", do it in the caller.
18506 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18508 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18510 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18511 (read_minibuf): Use get_minibuffer.
18512 (syms_of_minibuf): Use DEFSYM.
18513 (Qmetadata): New var.
18514 * data.c (Qbuffer): Don't make it static.
18515 (syms_of_data): Use DEFSYM.
18517 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18519 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18520 (CCL_CODE_MIN): New macro.
18522 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18524 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18526 * eval.c (Qdebug): Now static.
18527 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18528 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18529 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18531 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18533 * image.c: Various fixes to ImageMagick code comments.
18534 (Fimagemagick_types): Doc fix.
18536 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18538 Minor fixes prompted by GCC 4.6.0 warnings.
18540 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18542 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18543 (x_clipboard_manager_save_all): Move extern decl to ...
18544 * xterm.h: ... here, so that it can be checked for consistency.
18546 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18548 * xselect.c (x_clipboard_manager_save_frame)
18549 (x_clipboard_manager_save_all): New functions.
18550 (Fx_clipboard_manager_save): Lisp function deleted.
18552 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18553 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18555 * xterm.h: Update prototype.
18557 2011-05-28 William Xu <william.xwl@gmail.com>
18559 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18560 exiting (Bug#8239).
18562 2011-05-28 Jim Meyering <meyering@redhat.com>
18564 Avoid a sign-extension bug in crypto_hash_function.
18565 * fns.c (to_uchar): Define.
18566 (crypto_hash_function): Use it to convert some newly-signed
18567 variables to unsigned, to avoid sign-extension bugs. For example,
18568 without this change, (md5 "truc") would evaluate to
18569 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18570 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18571 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18573 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18575 Integer overflow fixes.
18577 * dbusbind.c: Serial number integer overflow fixes.
18578 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18579 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18580 to hold a serial number that is too large for a fixnum.
18581 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18582 Check for serial numbers out of range. Decode any serial number
18583 that was so large that it became a float. (Bug#8722)
18585 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18586 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18587 Use XFASTINT rather than XUINT when numbers are nonnegative.
18588 (xd_append_arg, Fdbus_method_return_internal):
18589 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18590 arguments, check that Lisp number is nonnegative, rather than
18591 silently wrapping negative numbers around. (Bug#8722)
18592 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18595 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18597 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18599 ccl: Add integer overflow checks.
18600 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18601 (IN_INT_RANGE): New macros.
18602 (ccl_driver): Use them to check for integer overflow when
18603 decoding a CCL program. Many of the new checks are whether XINT (x)
18604 fits in int; it doesn't always, on 64-bit hosts. The new version
18605 doesn't catch all possible integer overflows, but it's an
18606 improvement. (Bug#8719)
18608 * alloc.c (make_event_array): Use XINT, not XUINT.
18609 There's no need for unsigned here.
18611 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18612 This follows up to the 2011-05-06 change that substituted uintptr_t
18613 for EMACS_INT. This case wasn't caught back then.
18615 Rework Fformat to avoid integer overflow issues.
18616 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18617 now (part of C89). Include <verify.h>.
18618 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18619 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18620 (Fformat): Avoid the prepass trying to compute sizes; it was only
18621 approximate and thus did not catch overflow reliably. Instead, walk
18622 through the format just once, formatting and computing sizes as we go,
18623 checking for integer overflow at every step, and allocating a larger
18624 buffer as needed. Keep track separately whether the format is
18625 multibyte. Keep only the most-recently calculated precision, rather
18626 than them all. Record whether each argument has been converted to
18627 string. Use EMACS_INT, not int, for byte and char and arg counts.
18628 Support field widths and precisions larger than INT_MAX. Avoid
18629 sprintf's undefined behavior with conversion specifications such as %#d
18630 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18631 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18632 formatting out-of-range floating point numbers with int
18633 formats. (Bug#8668)
18635 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18637 * data.c: Avoid integer truncation in expressions involving floats.
18638 * data.c: Include <intprops.h>.
18639 (arith_driver): When there's an integer overflow in an expression
18640 involving floating point, convert the integers to floating point
18641 so that the resulting value does not suffer from catastrophic
18642 integer truncation. For example, on a 64-bit host (* 4
18643 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18644 Do not rely on undefined behavior after integer overflow.
18646 merge count_size_as_multibyte, parse_str_to_multibyte
18647 * character.c, character.h (count_size_as_multibyte):
18648 Rename from parse_str_to_multibyte; all uses changed.
18649 Check for integer overflow.
18650 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18651 since it's now a duplicate of the other. This is more of
18652 a character than a buffer op, so better that it's in character.c.
18653 * fns.c, print.c: Adjust to above changes.
18655 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18657 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18659 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18661 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18662 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18663 (x_clipboard_manager_save): Now static.
18664 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18666 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18667 (crypto_hash_function): Now static.
18668 Fix pointer signedness problems. Avoid unnecessary initializations.
18670 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18672 * termhooks.h (Vselection_alist): Make it terminal-local.
18674 * terminal.c (create_terminal): Initialize it.
18676 * xselect.c: Support for clipboard managers.
18677 (Vselection_alist): Move to termhooks.h as terminal-local var.
18678 (LOCAL_SELECTION): New macro.
18679 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18680 (symbol_to_x_atom): Remove gratuitous arg.
18681 (x_handle_selection_request, lisp_data_to_selection_data)
18682 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18683 (x_own_selection, x_get_local_selection, x_convert_selection):
18684 New arg, specifying work frame. Use terminal-local Vselection_alist.
18685 (some_frame_on_display): Delete unused function.
18686 (Fx_own_selection_internal, Fx_get_selection_internal)
18687 (Fx_disown_selection_internal, Fx_selection_owner_p)
18688 (Fx_selection_exists_p): New optional frame arg.
18689 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18690 (x_handle_selection_clear): Don't treat other terminals with the
18691 same keyboard specially. Use the terminal-local Vselection_alist.
18692 (x_clear_frame_selections): Use Frun_hook_with_args.
18694 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18696 * xterm.h: Add support for those atoms.
18698 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18700 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18701 (converted_selections, conversion_fail_tag): New global variables.
18702 (x_selection_request_lisp_error): Free the above.
18703 (x_get_local_selection): Remove unnecessary code.
18704 (x_reply_selection_request): Args changed; handle arbitrary array
18705 of converted selections stored in converted_selections.
18706 Separate the XChangeProperty and SelectionNotify steps.
18707 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18708 (x_convert_selection): New function.
18709 (x_handle_selection_event): Simplify.
18710 (x_get_foreign_selection): Don't ignore incoming requests while
18711 waiting for an answer; this will fail when we implement
18712 SAVE_TARGETS, and seems unnecessary anyway.
18713 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18714 (Vx_sent_selection_functions): Doc fix.
18716 2011-05-26 Leo Liu <sdl.web@gmail.com>
18718 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18720 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18722 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18724 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18725 for fringe update if it has periodic bitmap.
18726 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18727 and fringe_bitmap_periodic_p.
18729 * fringe.c (get_fringe_bitmap_data): New function.
18730 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18731 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18732 row. Mark glyph row for fringe update if periodicity changed.
18734 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18735 for fringe update unless it has periodic bitmap.
18737 2011-05-25 Kenichi Handa <handa@m17n.org>
18739 * xdisp.c (get_next_display_element): Set correct it->face_id for
18740 a static composition.
18742 2011-05-24 Leo Liu <sdl.web@gmail.com>
18745 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18747 * fns.c (crypto_hash_function, Fsha1): New function.
18748 (Fmd5): Use crypto_hash_function.
18749 (syms_of_fns): Add Ssha1.
18751 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18753 * gnutls.c: Remove unused macros.
18754 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18755 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18756 Remove macros that are defined and never used.
18757 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18759 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18761 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18762 (Fx_get_selection_internal): Minor cleanup.
18763 (Fx_own_selection_internal): Rename arguments for consistency with
18766 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18768 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18770 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18772 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18774 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18776 * dispnew.c (scrolling_window): Don't exclude the case that the
18777 last enabled row in the desired matrix touches the bottom boundary.
18779 2011-05-21 Glenn Morris <rgm@gnu.org>
18781 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18782 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18783 and add some more files.
18785 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18787 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18788 report_file_error introduced by the change from 2011-05-07.
18790 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18792 * systime.h (Time): Define only if emacs is defined.
18793 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18794 where the include path doesn't have X11/X.h by default. See
18795 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18797 2011-05-20 Kenichi Handa <handa@m17n.org>
18799 * composite.c (find_automatic_composition): Fix previous change.
18801 2011-05-20 Glenn Morris <rgm@gnu.org>
18803 * lisp.mk: New file, split from Makefile.in.
18804 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18805 (shortlisp): Remove.
18806 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18808 2011-05-19 Glenn Morris <rgm@gnu.org>
18810 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18811 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18812 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18813 (lisp): Set the order to that of loadup.el.
18814 (shortlisp): Make it a copy of $lisp.
18815 (SOME_MACHINE_LISP): Remove.
18816 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18817 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18819 2011-05-18 Kenichi Handa <handa@m17n.org>
18821 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18822 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18823 (find_automatic_composition): Mostly rewrite for efficiency.
18825 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18827 * makefile.w32-in: Update dependencies.
18829 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18831 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18832 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18834 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18836 Fix some integer overflow issues, such as string length overflow.
18838 * insdel.c (count_size_as_multibyte): Check for string overflow.
18840 * character.c (lisp_string_width): Check for string overflow.
18841 Use EMACS_INT, not int, for string indexes and lengths; in
18842 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18843 the resulting string length overflows an EMACS_INT; instead,
18844 report a string overflow if no precision given. When checking for
18845 precision exhaustion, use a check that cannot possibly have
18846 integer overflow. (Bug#8675)
18847 * character.h (lisp_string_width): Adjust to new signature.
18849 * alloc.c (string_overflow): New function.
18850 (Fmake_string): Use it. This doesn't change behavior, but saves
18851 a few bytes and will simplify future changes.
18852 * character.c (string_escape_byte8): Likewise.
18853 * lisp.h (string_overflow): New decl.
18855 Fixups, following up to the user-interface timestamp change.
18856 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18857 for UI timestamps, instead of unsigned long.
18858 * msdos.c (mouse_get_pos): Likewise.
18859 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18860 * w32gui.h (Time): Define by including "systime.h" rather than by
18861 declaring it ourselves. (Bug#8664)
18863 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18864 * image.c (clear_image_cache): Likewise.
18866 * term.c (term_mouse_position): Don't assume time_t wraparound.
18868 Be more systematic about user-interface timestamps.
18869 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18870 and sometimes 'EMACS_UINT', to represent these timestamps.
18871 This change causes it to use 'Time' uniformly, as that's what X uses.
18872 This makes the code easier to follow, and makes it easier to catch
18873 integer overflow bugs such as Bug#8664.
18874 * frame.c (Fmouse_position, Fmouse_pixel_position):
18875 Use Time, not unsigned long, for user-interface timestamps.
18876 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18877 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18878 * keyboard.h (last_event_timestamp): Likewise.
18879 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18880 * menu.h (xmenu_show): Likewise.
18881 * term.c (term_mouse_position): Likewise.
18882 * termhooks.h (struct input_event.timestamp): Likewise.
18883 (struct terminal.mouse_position_hook): Likewise.
18884 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18885 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18886 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18887 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18888 what it was before.
18889 * menu.h, termhooks.h: Include "systime.h", for Time.
18891 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18892 Don't assume that the difference between two unsigned long values
18893 can fit into an integer. At this point, we know button_down_time
18894 <= event->timestamp, so the difference must be nonnegative, so
18895 there's no need to cast the result if double-click-time is
18896 nonnegative, as it should be; check that it's nonnegative, just in
18897 case. This bug is triggered when events are more than 2**31 ms
18898 apart (about 25 days). (Bug#8664)
18900 * xselect.c (last_event_timestamp): Remove duplicate decl.
18901 (x_own_selection): Remove needless cast to unsigned long.
18903 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18904 that always fit in int. Use a sentinel instead of a counter, to
18905 avoid a temp and to allay GCC's concerns about possible int overflow.
18906 * frame.h (struct frame): Use int for menu_bar_items_used
18907 instead of EMACS_INT, since it always fits in int.
18909 * menu.c (grow_menu_items): Check for int overflow.
18911 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18913 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18914 Before, the code was not consistent. These values cannot exceed
18915 2**31 - 1 so there's no need to make them unsigned.
18916 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18917 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18918 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18920 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18922 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18923 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18924 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18925 presumably because the widths might not match.
18927 * window.c (size_window): Avoid needless test at loop start.
18929 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18931 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18933 2011-05-12 Drew Adams <drew.adams@oracle.com>
18935 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18937 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18939 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18940 `width' to `bar_area_x' and `bar_area_width', respectively.
18941 (x_scroll_run): Take account of fringe background extension.
18943 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18944 Rename local vars `left' and `width' to `bar_area_x' and
18945 `bar_area_width', respectively.
18946 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18947 background extension.
18949 2011-05-10 Jim Meyering <meyering@redhat.com>
18951 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18953 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18955 * image.c (Finit_image_library): Return t for built-in image types,
18956 like pbm and xbm. (Bug#8640)
18958 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18960 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18962 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18964 * w32console.c (Fset_screen_color): Doc fix.
18965 (Fget_screen_color): New function.
18966 (syms_of_ntterm): Defsubr it.
18968 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18969 unlink the temporary file if Fcall_process didn't create it in the
18971 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18972 child process will be redirected to a file specified with `:file'.
18973 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18974 cue to call_process_cleanup not to close that handle.
18976 2011-05-07 Ben Key <bkey76@gmail.com>
18978 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18979 one of two shell specific rules, either bootstrap-temacs-CMD or
18980 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18981 to the previous implementation of the bootstrap-temacs rule.
18982 The bootstrap-temacs-CMD rule is similar to the previous
18983 implementation of the bootstrap-temacs rule except that it
18984 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18987 These changes, along with some changes to nt/configure.bat,
18988 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18989 earlier fix to add support for --cflags and --ldflags options
18990 that include quotes so that it works whether make uses cmd or
18993 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18995 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18996 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18998 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18999 a string. Handle both cases.
19000 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19001 (Fdbus_register_method): Use Qinvalid_function.
19003 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19005 * makefile.w32-in: Update dependencies.
19006 (LISP_H): Add inttypes.h and stdin.h.
19007 (PROCESS_H): Add unistd.h.
19009 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19011 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19012 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19014 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19016 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19018 * term.c (vfatal): Remove stray call to va_end.
19019 It's not needed and the C Standard doesn't allow it here anyway.
19021 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19022 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19024 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19027 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19029 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19031 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19033 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19035 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19037 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19038 * charset.c (Fdefine_charset_internal): Don't initialize
19039 charset.code_space[15]. The value was garbage, on hosts with
19040 32-bit int (Bug#8600).
19042 * lread.c (read_integer): Be more consistent with string-to-number.
19043 Use string_to_number to do the actual conversion; this avoids
19044 rounding errors and fixes some other screwups. Without this fix,
19045 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19046 (digit_to_number): Move earlier, for benefit of read_integer.
19047 Return -1 if the digit is out of range for the base, -2 if it is
19048 not a digit in any supported base. (Bug#8602)
19050 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19052 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19053 to match comment at start of function. This also removes a
19054 GCC warning about overflow in a 32+64-bit port.
19056 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19058 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19059 Reported by Stefan Monnier in
19060 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19061 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19062 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19064 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19065 (EMACS_UINTPTR): Likewise, with uintptr_t.
19067 * lisp.h: Prefer 64-bit EMACS_INT if available.
19068 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19069 on 32-bit hosts that have 64-bit int, so that they can access
19071 However, temporarily disable this change unless the temporary
19072 symbol WIDE_EMACS_INT is defined.
19074 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19076 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19077 This removes an assumption that EMACS_INT and long are the same
19078 width as pointers. The assumption is true for Emacs porting targets
19079 now, but we want to make other targets possible.
19080 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19081 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19082 In the rest of the code, change types of integers that hold casted
19083 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19084 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19085 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19086 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19087 No need to cast type when ORing.
19088 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19089 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19090 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19091 assume EMACS_INT is the same width as char *.
19092 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19093 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19094 Remove no-longer-needed casts.
19095 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19096 (xg_tool_bar_help_callback, xg_make_tool_item):
19097 Use EMACS_INTPTR to hold an integer
19098 that will be cast to void *; this can avoid a GCC warning
19099 if EMACS_INT is not the same width as void *.
19100 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19101 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19102 (current_message_1, set_message_1):
19103 Use a local to convert to proper width without a cast.
19104 * xmenu.c (dialog_selection_callback): Likewise.
19106 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19107 Also, don't assume VALBITS / RAND_BITS is less than 5,
19108 and don't rely on undefined behavior when shifting a 1 left into
19110 * lisp.h (get_random): Change signature to match.
19112 * lread.c (hash_string): Use size_t, not int, for hash computation.
19113 Normally we prefer signed values; but hashing is special, because
19114 it's better to use unsigned division on hash table sizes so that
19115 the remainder is nonnegative. Also, size_t is the natural width
19116 for hashing into memory. The previous code used 'int', which doesn't
19117 retain enough info to hash well into very large tables.
19118 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19120 * dbusbind.c: Don't possibly lose pointer info when converting.
19121 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19122 Use XPNTR rather than XHASH, so that the high-order bits of
19123 the pointer aren't lost when converting through void *.
19125 * eval.c (Fautoload): Don't double-shift a pointer.
19127 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

19161 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19162 Remove unused parameter `fildes'.
19163 * process.c (read_process_output, send_process): Don't pass it.
19165 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19167 Fix previous change: the library cache is defined in w32.c.
19168 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19169 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

19211 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19212 instead of gnutls_record_check_pending.
19214 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19216 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19218 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19219 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19222 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19224 * xterm.c (x_set_frame_alpha): Do not set property on anything

19261 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19263 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19264 rather than `XVECTOR (FOO)->size'.
19266 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19267 inttypes.h, as a gnulib replacement is used if it not available in
19270 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19272 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19273 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19274 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19276 * coding.c (coding_alloc_by_realloc): Error out if destination
19277 will grow beyond MOST_POSITIVE_FIXNUM.
19278 (decode_coding_emacs_mule): Abort if there isn't enough place in
19279 charbuf for the composition carryover bytes. Reserve an extra

19316 * doprnt.c (doprnt): Don't return value smaller than the buffer
19317 size if the message was truncated. (Bug#8545).

19332 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19334 Improve `doprnt' and its usage. (Bug#8545)
19335 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19336 `format_end'. Remove support for %l as a conversion specifier.
19337 Don't use xrealloc. Improve diagnostics when the %l size modifier
19338 is used. Update the commentary.
19340 * eval.c (verror): Simplify calculation of size_t.
19342 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19345 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19347 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19350 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19352 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19353 This makes this file independent of the recent pseudovector change.
19355 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19357 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19359 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19360 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19361 Remove unused local.
19362 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19364 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19365 GCC 4.6.0 optimizes based on type-based alias analysis.
19366 For example, if b is of type struct buffer * and v of type struct
19367 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19368 != &v->size, and therefore "v->size = 1; b->size = 2; return
19369 v->size;" must therefore return 1. This assumption is incorrect
19370 for Emacs, since it type-puns struct Lisp_Vector * with many other
19371 types. To fix this problem, this patch adds a new type struct
19372 vectorlike_header that documents the constraints on layout of vectors
19373 and pseudovectors, and helps optimizing compilers not get fooled
19374 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19375 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19376 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19378 (XSETPVECTYPE): Rewrite in terms of new macro.
19379 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19380 This is a bit clearer, and further avoids the possibility of
19381 undesirable aliasing.
19382 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19383 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19384 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19385 since Lisp_Subr is a special case (no "next" field).
19386 (ASIZE): Now uses header.size rather than size.
19387 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19388 to avoid the hassle of writing XVECTOR (foo)->header.size.
19389 (struct vectorlike_header): New type.
19390 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19391 object, to help avoid aliasing.
19392 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19393 (SUBRP): Likewise, since Lisp_Subr is a special case.
19394 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19395 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19396 (struct Lisp_Hash_Table): Combine first two members into a single
19397 struct vectorlike_header member. All uses of "size" and "next" members
19398 changed to be "header.size" and "header.next".
19399 * buffer.h (struct buffer): Likewise.
19400 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19401 * frame.h (struct frame): Likewise.
19402 * process.h (struct Lisp_Process): Likewise.
19403 * termhooks.h (struct terminal): Likewise.
19404 * window.c (struct save_window_data, struct saved_window): Likewise.
19405 * window.h (struct window): Likewise.
19406 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19407 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19408 * buffer.c (init_buffer_once): Likewise.
19409 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19411 * process.c (Fformat_network_address): Use local var for size,
19414 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19416 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19417 * data.c (atof): Remove decl; no longer used or needed.
19418 (digit_to_number): Move to lread.c.
19419 (Fstring_to_number): Use new string_to_number function, to be
19420 consistent with how the Lisp reader treats infinities and NaNs.
19421 Do not assume that floating-point numbers represent EMACS_INT
19422 without losing information; this is not true on most 64-bit hosts.
19423 Avoid double-rounding errors, by insisting on integers when
19424 parsing non-base-10 numbers, as the documentation specifies.
19425 * lisp.h (string_to_number): New decl, replacing ...
19426 (isfloat_string): Remove.
19427 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19428 (read1): Do not accept +. and -. as integers; this
19429 appears to have been a coding error. Similarly, do not accept
19430 strings like +-1e0 as floating point numbers. Do not report
19431 overflow for integer overflows unless the base is not 10 which
19432 means we have no simple and reliable way to continue.
19433 Break out the floating-point parsing into a new
19434 function string_to_number, so that Fstring_to_number parses
19435 floating point numbers consistently with the Lisp reader.
19436 (digit_to_number): Move here from data.c. Make it static inline.
19437 (E_CHAR, EXP_INT): Remove, replacing with ...
19438 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19439 (string_to_number): New function, replacing isfloat_string.
19440 This function checks for valid syntax and produces the resulting
19441 Lisp float number too. Rework it so that string-to-number
19442 no longer mishandles examples like "1.0e+". Use strtoumax,
19443 so that overflow for non-base-10 numbers is reported only when
19444 there's no portable and simple way to convert to floating point.
19446 * textprop.c (set_text_properties_1): Rewrite for clarity,
19447 and to avoid GCC warning about integer overflow.
19449 * intervals.h (struct interval): Use EMACS_INT for members
19450 where EMACS_UINT might cause problems. See
19451 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19452 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19453 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19455 (offset_intervals): Tell GCC not to worry about length overflow
19456 when negating a negative length.
19458 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19459 (overrun_check_free): Likewise.
19461 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19462 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19465 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19466 (gnutls_make_error): Rename local to avoid shadowing.
19467 (gnutls_emacs_global_deinit): ifdef out; not used.
19468 (Fgnutls_boot): Use const for pointer to readonly storage.
19469 Comment out unused local. Fix pointer signedness problems.
19471 * lread.c (openp): Don't stuff size_t into an 'int'.
19472 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19473 about possible signed overflow.
19475 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19476 (GDK_KEY_g): Don't define if already defined.
19477 (xg_prepare_tooltip): Avoid pointer signedness problem.
19478 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19480 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19481 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19483 * xfns.c (Fx_window_property): Simplify a bit,
19484 to make a bit faster and to avoid GCC 4.6.0 warning.
19485 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19487 * fns.c (internal_equal): Don't assume size_t fits in int.
19489 * alloc.c (compact_small_strings): Tighten assertion a little.
19491 Replace pEd with more-general pI, and fix some printf arg casts.
19492 * lisp.h (pI): New macro, generalizing old pEd macro to other
19493 conversion specifiers. For example, use "...%"pI"d..." rather
19494 than "...%"pEd"...".
19495 (pEd): Remove. All uses replaced with similar uses of pI.
19496 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19497 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19498 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19499 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19500 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19501 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19502 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19504 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19505 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19506 * print.c (safe_debug_print, print_object): Likewise.
19507 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19509 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19510 avoiding the 0 flag, which is not portable.
19511 * process.c (Fmake_network_process): Use pI to avoid cast.
19512 * region-cache.c (pp_cache): Likewise.
19513 * xdisp.c (decode_mode_spec): Likewise.
19514 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19515 behavior on 64-bit hosts with printf arg.
19516 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19517 (x_stop_queuing_selection_requests): Likewise.
19518 (x_get_window_property): Don't truncate byte count to an 'int'
19521 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19522 here, since it parses constructs like leading '-' and spaces,
19523 which are not wanted; and it overflows with large numbers.
19524 Instead, simply match F[0-9]+, which is what is wanted anyway.
19526 * alloc.c: Remove unportable assumptions about struct layout.
19527 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19528 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19529 (allocate_vectorlike, make_pure_vector): Use the new macros,
19530 plus offsetof, to remove unportable assumptions about struct layout.
19531 These assumptions hold on all porting targets that I know of, but
19532 they are not guaranteed, they're easy to remove, and removing them
19533 makes further changes easier.
19535 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19536 This doesn't fix a bug but makes the code clearer.
19537 (string_overrun_cookie): Now const. Use initializers that
19538 don't formally overflow signed char, to avoid warnings.
19539 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19540 can cause Emacs to crash when string overrun checking is enabled.
19541 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19542 multiple of sizeof (EMACS_INT); it need not be, if
19543 alignof(EMACS_INT) < sizeof (EMACS_INT).
19544 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

19575 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19576 "cast to pointer from integer of different size".
19578 Improve doprnt and its use in verror. (Bug#8545)
19579 * doprnt.c (doprnt): Document the set of format control sequences
19580 supported by the function. Use SAFE_ALLOCA instead of always
19583 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19584 is one byte too soon. Don't use xrealloc; instead xfree and

19596 docstring. Start callback support.
19597 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19598 unless a fatal error occurred. Call gnutls_alert_send_appropriate

19702 codepoint of an invalid character, to avoid displaying a bogus
19705 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19706 `error', not SYMBOL_NAME itself.
19708 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19709 character arguments to `error'.
19711 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19712 to `error' in error message about FINAL_CHAR argument. Make sure
19713 FINAL_CHAR is a character, and use %c when it is passed as
19714 argument to `error'.
19716 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19718 * s/ms-w32.h (localtime): Redirect to sys_localtime.
19720 * w32.c: Include <time.h>.

19784 * dispextern.h (struct redisplay_interface): Rename param
19785 to avoid shadowing.
19786 * termhooks.h (struct terminal): Likewise.

19903 * nsfont.m: Fixed bugs in ns_get_family and
19904 ns_descriptor_to_entity that were caused by using free to
19905 deallocate memory blocks that were allocated by xmalloc (via
19906 xstrdup). This caused Emacs to crash when compiled with
19907 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19908 --enable-checking=xmallocoverrun). xfree is now used to
19909 deallocate these memory blocks.

19925 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
19926 (emacs_read, emacs_write): Use it.
19927 * process.c (send_process): Adjust to the new signatures of
19928 emacs_write and emacs_gnutls_write. Do not attempt to store

20407 is outside the buffer's accessible region. (Bug#8468)
20409 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20411 Fix write-region and its subroutines for buffers > 2GB.
20412 * fileio.c (a_write, e_write): Modify declaration of arguments and
20413 local variables to support buffers larger than 2GB.
20414 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20416 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20417 argument, local variables, and return value.
20419 * lisp.h: Update prototypes of emacs_write and emacs_read.
20421 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20423 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20425 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20427 Fix more problems found by GCC 4.6.0's static checks.
20429 * xdisp.c (vmessage): Use a better test for character truncation.
20431 * charset.c (load_charset_map): <, not <=, for optimization,
20432 and to avoid potential problems with integer overflow.
20433 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20434 * casetab.c (set_identity, shuffle): Likewise.
20435 * editfns.c (Fformat): Likewise.
20436 * syntax.c (skip_chars): Likewise.
20438 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20439 This also lets GCC 4.6.0 generate slightly better loop code.
20441 * callint.c (Fcall_interactively): <, not <=, for optimization.
20442 (Fcall_interactively): Count the number of arguments produced,
20443 not the number of arguments given. This is simpler and lets GCC
20444 4.6.0 generate slightly better code.
20446 * ftfont.c: Distingish more carefully between FcChar8 and char.
20447 The previous code passed unsigned char * to a functions like
20448 strlen and xstrcasecmp that expect char *, which does not
20449 conform to the C standard.
20450 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20451 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20452 char * when the C standard requires it.
20454 * keyboard.c (read_char): Remove unused var.
20456 * eval.c: Port to Windows vsnprintf (Bug#8435).
20457 Include <limits.h>.
20458 (SIZE_MAX): Define if the headers do not.
20459 (verror): Do not give up if vsnprintf returns a negative count.
20460 Instead, grow the buffer. This ports to Windows vsnprintf, which
20461 does not conform to C99. Problem reported by Eli Zaretskii.
20462 Also, simplify the allocation scheme, by avoiding the need for
20463 calling realloc, and removing the ALLOCATED variable.
20465 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20467 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20468 But keep the doprint source code for now, as we might revamp it
20469 and use it again (Bug#8435).
20470 * lisp.h (doprnt): Remove.
20471 * Makefile.in (base_obj): Remove doprnt.o.
20472 * deps.mk (doprnt.o): Remove.
20474 error: Print 32- and 64-bit integers portably (Bug#8435).
20475 Without this change, on typical 64-bit hosts error ("...%d...", N)
20476 was used to print both 32- and 64-bit integers N, which relied on
20477 undefined behavior.
20478 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20479 * lisp.h (error, verror): Mark as printf-like functions.
20480 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20481 Report overflow in size calculations when allocating printf buffer.
20482 Do not truncate output string at its first null byte.
20483 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20484 Truncate the output at a character boundary, since vsnprintf does not
20486 * charset.c (check_iso_charset_parameter): Convert internal
20487 character to string before calling 'error', since %c now has the
20489 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20490 overflow when computing char to be passed to 'error'. Do not
20491 pass Lisp_Object to 'error'; pass the integer instead.
20492 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20493 formatted with plain %d.
20495 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20497 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20499 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20501 * xterm.c (x_catch_errors): Remove duplicate declaration.
20503 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20505 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20507 2011-04-10 Jim Meyering <meyering@redhat.com>
20509 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20510 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20511 return ssize_t not "int", and use size_t as the buffer length.
20512 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20513 * gnutls.h: Update declarations.
20514 * process.c (read_process_output): Use ssize_t, to match.
20515 (send_process): Likewise.
20517 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20519 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20521 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20523 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20524 Use unsigned char, to match FcChar8 type definition.
20526 * xterm.c (handle_one_xevent):
20527 * xmenu.c (create_and_show_popup_menu):
20528 * xselect.c (x_decline_selection_request)
20529 (x_reply_selection_request): Avoid type-punned deref of X events.
20531 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20533 Fix some uses of `int' instead of EMACS_INT.
20534 * search.c (string_match_1, fast_string_match)
20535 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20536 (scan_buffer, find_next_newline_no_quit)
20537 (find_before_next_newline, search_command, Freplace_match)
20538 (Fmatch_data): Make some `int' variables be EMACS_INT.
20540 * xdisp.c (display_count_lines): 3rd argument and return value now
20541 EMACS_INT. All callers changed.
20542 (pint2hrstr): Last argument is now EMACS_INT.
20544 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20545 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20546 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20547 (decode_coding_utf_16, decode_coding_emacs_mule)
20548 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20549 (decode_coding_ccl, decode_coding_charset)
20550 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20551 (decode_coding_iso_2022, decode_coding_emacs_mule)
20552 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20553 <char_offset, last_offset>: Declare EMACS_INT.
20554 (encode_coding_utf_8, encode_coding_utf_16)
20555 (encode_coding_emacs_mule, encode_invocation_designation)
20556 (encode_designation_at_bol, encode_coding_iso_2022)
20557 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20558 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20560 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20561 (encode_invocation_designation): Last argument P_NCHARS is now
20563 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20564 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20566 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20569 * ccl.c (Fccl_execute_on_string): Declare some variables
20572 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20574 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20576 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20578 * process.c (Fformat_network_address): Doc fix.
20580 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20582 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20584 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20586 * keyboard.c (read_char): Call Lisp function help-form-show,
20587 instead of using internal_with_output_to_temp_buffer.
20588 (Qhelp_form_show): New var.
20589 (syms_of_keyboard): Use DEFSYM macro.
20591 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20593 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20595 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20597 * process.c (Flist_processes): Remove to Lisp.
20598 (list_processes_1): Delete.

20602 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20604 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20606 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20608 Fix more problems found by GCC 4.6.0's static checks.
20610 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20612 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20614 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20616 * xdisp.c (vmessage): Mark as a printf-like function.
20618 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20620 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20622 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20623 printf-like functions.
20624 (tiff_load): Add casts to remove these marks before passing them
20625 to system-supplied API.
20627 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20629 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20630 This avoids several warnings with gcc -Wstrict-overflow.
20631 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20632 directly, rather than having caller test rule sign. This avoids
20633 some unnecessary tests.
20634 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20635 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20636 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20638 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20639 (xfont_open): Avoid unnecessary tests.
20641 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20643 * composite.h, composite.c (composition_gstring_put_cache):
20644 Use EMACS_INT, not int, for length.

20647 breaking out part of COMPOSITION_DECODE_RULE.
20648 (COMPOSITION_DECODE_RULE): Use it.
20649 * composite.c (get_composition_id): Remove unused local vars,
20650 by using the new macro.
20652 * textprop.c (set_text_properties_1): Change while to do-while,
20653 since the condition is always true at first.
20655 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20656 (interval_deletion_adjustment): Return unsigned value.
20659 * process.c (list_processes_1, create_pty, read_process_output):

20669 (update_syntax_table): Use unsigned instead of int.
20671 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20672 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20673 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20675 * print.c (print_error_message): Avoid int overflow.
20677 * font.c (font_list_entities): Redo for clarity,
20678 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20680 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20681 (font_score): Avoid potential overflow in diff calculation.
20683 * fns.c (substring_both): Remove var that is set but not used.
20684 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20686 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20688 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20689 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20690 can always succeed if overflow has undefined behavior.
20692 * search.c (boyer_moore, wordify): Remove vars set but not used.
20693 (wordify): Omit three unnecessary tests.
20695 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20696 All callers changed. This avoids the need for an unused var.
20698 * casefiddle.c (casify_region): Remove var that is set but not used.
20700 * dired.c (file_name_completion): Remove var that is set but not used.
20702 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20704 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20705 (Finsert_file_contents): Remove unnecessary code checking fd.
20707 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20708 Check for integer overflow on size calculations.
20710 * buffer.c (Fprevious_overlay_change): Remove var that is set
20713 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20714 Remove vars that are set but not used.
20715 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20716 (timer_check_2): Mark vars as initialized.
20718 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20720 * image.c (lookup_image): Remove var that is set but not used.
20721 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20723 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20724 that are set but not used.
20726 * xfns.c (make_invisible_cursor): Don't return garbage
20727 if XCreateBitmapFromData fails (Bug#8410).
20729 * xselect.c (x_get_local_selection, x_handle_property_notify):
20730 Remove vars that are set but not used.
20732 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

20742 (map_tty_color) [!defined MSDOS]: Likewise.
20744 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20746 * coding.c: Remove vars that are set but not used.
20747 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20748 All callers changed.

20750 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20751 (decode_coding_charset): Remove vars that are set but not used.
20753 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20754 that is set but not used.
20756 * print.c (print_object): Remove var that is set but not used.
20758 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20759 The gnulib version avoids calling malloc in the usual case,
20760 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20761 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20762 * filelock.c (current_lock_owner): Likewise.
20763 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

20767 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20768 ../lib/careadlinkat.h.
20770 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20772 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20773 first non-nil return value).

20787 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20788 and thereabouts. All callers changed.
20789 (get_per_char_metric): Remove parameter `f', unused since
20790 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20872 (try_scrolling): Use it when setting scroll_limit.
20873 Limit scrolling to 100 screen lines.
20874 (redisplay_window): Even when falling back on "recentering",
20875 position point in the window according to scroll-conservatively,
20876 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20878 (try_scrolling): When point is above the window, allow searching
20879 as far as scroll_max, or one screenful, to compute vertical
20880 distance from PT to the scroll margin position. This prevents
20881 try_scrolling from unnecessarily failing when
20882 scroll-conservatively is set to a value slightly larger than the
20883 window height. Clean up the case of PT below the margin at bottom
20884 of window: scroll_max can no longer be INT_MAX. When aggressive
20885 scrolling is in use, don't let point enter the opposite scroll
20886 margin as result of the scroll.
20887 (syms_of_xdisp) <scroll-conservatively>: Document the
20888 threshold of 100 lines for never-recentering scrolling.
20890 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20892 * dispextern.h (move_it_by_lines):
20893 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20894 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20895 (message_log_check_duplicate): Remove parameters `prev_bol' and
20896 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20897 (redisplay_internal): Remove parameter `preserve_echo_area',
20898 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20900 * indent.c (Fvertical_motion):
20901 * window.c (window_scroll_pixel_based, Frecenter):
20902 Don't pass `need_y_p' to `move_it_by_lines'.
20904 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20906 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20907 steal a few bits to be more compact.
20908 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20909 Remove unneeded casts.
20911 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20913 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20915 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20916 binding" message (bug#7967).
20918 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20920 Fix more problems found by GCC 4.6.0's static checks.
20922 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20923 Remove unused local var.
20925 * editfns.c (Fmessage_box): Remove unused local var.
20927 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20928 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20929 Omit unused local vars.
20930 * window.c (shrink_windows): Omit unused local var.
20931 * menu.c (digest_single_submenu): Omit unused local var.
20932 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20933 Omit unused local var.
20935 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20936 Don't assume string length fits in int.
20937 (keyremap_step, read_key_sequence): Use size_t for sizes.
20938 (read_key_sequence): Don't check last_real_key_start redundantly.
20940 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20941 instead of alloca (Bug#8344).
20943 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20944 (Fbacktrace_frame): Don't assume nframes fits in int.
20946 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20948 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20951 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20953 * cm.c (calccost): Turn while-do into do-while, for clarity.
20955 * keyboard.c (syms_of_keyboard): Use the same style as later
20956 in this function when indexing through an array. This also
20957 works around GCC bug 48267.
20959 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20961 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20963 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20964 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20966 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20967 This avoids undefined behavior on integer overflow, and is a bit
20968 more convenient anyway since it is compared to a size_t variable.
20970 Variadic C functions now count arguments with size_t, not int.
20971 This avoids an unnecessary limitation on 64-bit machines, which
20972 caused (substring ...) to crash on large vectors (Bug#8344).
20973 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20974 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

20978 * editfns.c (general_insert_function): Likewise.
20979 * eval.c (struct backtrace.nargs, interactive_p)
20980 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20981 (funcall_lambda, mark_backtrace): Likewise.
20982 * fns.c (concat): Likewise.
20983 * frame.c (x_set_frame_parameters): Likewise.
20984 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20985 0 if not found, not -1. All callers changed.
20987 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20988 (stack_copy_size): Now size_t, not int.
20989 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20991 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20993 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20994 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20995 All callers changed.
20997 * lisp.h (multibyte_char_to_unibyte):
20998 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20999 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21000 * character.h (CHAR_TO_BYTE8):
21001 * cmds.c (internal_self_insert):
21002 * editfns.c (general_insert_function):
21003 * keymap.c (push_key_description):
21004 * search.c (Freplace_match):
21005 * xdisp.c (message_dolog, set_message_1): All callers changed.
21007 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21009 * keyboard.c (safe_run_hook_funcall): New function.
21010 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21011 don't set the hook to nil, but remove the offending function instead.
21012 (Qcommand_hook_internal): Remove, unused.
21013 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21014 Vcommand_hook_internal.
21016 * eval.c (enum run_hooks_condition): Remove.
21017 (funcall_nil, funcall_not): New functions.
21018 (run_hook_with_args): Call each function through a `funcall' argument.
21019 Remove `cond' argument, now redundant.
21020 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21021 (Frun_hook_with_args_until_failure): Adjust accordingly.
21022 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21024 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21026 * dispextern.h (string_buffer_position): Remove declaration.
21028 * print.c (strout): Remove parameter `multibyte', unused since
21029 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21031 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21032 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21033 All callers changed.
21035 * w32.c (_wsa_errlist): Use braces for struct initializers.
21037 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21038 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21039 All callers changed.
21040 (string_buffer_position): Likewise. Also, make static (it's never
21041 used outside xdisp.c).

21045 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21046 All callers changed.
21048 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21050 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21061 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21063 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21065 * nsmenu.m (runDialogAt): Remove argument to timer_check.
21067 2011-03-27 Glenn Morris <rgm@gnu.org>

21070 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
21071 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
21072 Replace SIGTYPE with void everywhere.
21073 * s/usg5-4-common.h (SIGTYPE): Remove definition.

21076 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21078 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21079 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21081 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21083 * w32.c (read_unc_volume): Use parameter `henum', instead of
21084 global variable `wget_enum_handle'.
21086 * keymap.c (describe_vector): Remove parameters `indices' and
21087 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21090 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21092 * keyboard.c (timer_check): Remove parameter `do_it_now',
21093 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
21094 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
21095 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
21097 * keyboard.c (read_char):
21098 * w32menu.c (w32_menu_display_help):
21099 * xmenu.c (show_help_event, menu_help_callback):
21100 Adjust calls to `show_help_echo'.
21102 * gtkutil.c (xg_maybe_add_timer):
21103 * keyboard.c (readable_events):
21104 * process.c (wait_reading_process_output):
21105 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21107 * insdel.c (adjust_markers_gap_motion):
21108 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

21162 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
21163 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
21164 (Fx_close_connection): Remove unused variable `i'.

21182 2011-03-23 Julien Danjou <julien@danjou.info>
21184 * term.c (Fsuspend_tty, Fresume_tty):
21185 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21186 * window.c (temp_output_buffer_show):
21187 * insdel.c (signal_before_change):
21188 * frame.c (Fhandle_switch_frame):
21189 * fileio.c (Fdo_auto_save):
21190 * emacs.c (Fkill_emacs):
21191 * editfns.c (save_excursion_restore):
21192 * cmds.c (internal_self_insert):
21193 * callint.c (Fcall_interactively):
21194 * buffer.c (Fkill_all_local_variables):
21195 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21197 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21198 unconditionally since it does the check itself.
21200 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21202 Fix more problems found by GCC 4.5.2's static checks.
21204 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21205 the first time through the loop, since we know p0 < p1 then.
21206 This also avoids a gcc -Wstrict-overflow warning.
21208 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21209 leading to a memory leak, possible in functions like
21210 load_charset_map_from_file that can allocate an unbounded number
21211 of objects (Bug#8318).
21213 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21214 that could (at least in theory) be that large.
21216 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21217 This is less likely to overflow, and avoids undefined behavior if
21218 overflow does occur. All callers changed. Use strtoul to scan
21219 for the unsigned long integer.
21220 (pint2hrstr): Simplify and tune code slightly.
21221 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21223 * scroll.c (do_scrolling): Work around GCC bug 48228.
21224 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21226 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21227 This also avoids a warning with gcc -Wstrict-overflow.
21228 (validate_x_resource_name): Simplify count usage.
21229 This also avoids a warning with gcc -Wstrict-overflow.
21231 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21234 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21236 * process.c (Fmake_network_process): Use socklen_t, not int,
21237 where POSIX says socklen_t is required in portable programs.
21238 This fixes a porting bug on hosts like 64-bit HP-UX, where
21239 socklen_t is wider than int (Bug#8277).
21240 (Fmake_network_process, server_accept_connection):
21241 (wait_reading_process_output, read_process_output):
21244 * process.c: Rename or move locals to avoid shadowing.

21246 (read_process_output_error_handler, exec_sentinel_error_handler):
21247 Rename or move locals.
21248 (Fmake_network_process): Define label "retry_connect" only if needed.
21249 (Fnetwork_interface_info): Fix pointer signedness.
21250 (process_send_signal): Add cast to avoid pointer signedness problem.
21251 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21252 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21254 Make tparam.h and terminfo.c consistent.
21255 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21256 Include tparam.h instead, since it declares them.
21257 * cm.h (PC): Remove extern decl; tparam.h now does this.
21258 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21259 * terminfo.c: Include tparam.h, to check interfaces.
21260 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21261 (tparam): Adjust signature to match interface in tparam.h;
21262 this removes some undefined behavior. Check that outstring and len
21263 are zero, which they always are with Emacs.
21264 * tparam.h (PC, BC, UP): New extern decls.
21266 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21267 (xftfont_open): Rename locals to avoid shadowing.
21269 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21270 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21271 (OTF_TAG_SYM): Omit macro if not needed.
21272 (ftfont_list): Remove unused local.
21273 (get_adstyle_property, ftfont_pattern_entity):
21274 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21275 Rename locals to avoid shadowing.
21277 * xfont.c (xfont_list_family): Mark var as initialized.
21279 * xml.c (make_dom): Now static.
21281 * composite.c (composition_compute_stop_pos): Rename local to
21283 (composition_reseat_it): Remove unused locals.
21284 (find_automatic_composition, composition_adjust_point): Likewise.
21285 (composition_update_it): Mark var as initialized.
21286 (find_automatic_composition): Mark vars as initialized,
21287 with a FIXME (Bug#8290).
21289 character.h: Rename locals to avoid shadowing.
21290 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21291 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21292 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21293 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21294 to avoid shadowing.
21296 * textprop.c (property_change_between_p): Remove; unused.

21313 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21315 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21316 clobbering (Bug#8298).
21317 * sysdep.c (sys_subshell): Likewise.
21318 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21320 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21321 This should get cleaned up, so that child_setup has the
21322 same signature on all platforms.
21324 * callproc.c (call_process_cleanup): Now static.
21325 (relocate_fd): Rename locals to avoid shadowing.
21327 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

21455 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21456 some of which prompt warnings from gcc -Wbad-function-cast.
21457 (Fformat_time_string, Fencode_time, Finsert_char):
21458 (Ftranslate_region_internal, Fformat):

21486 (Fmemory_limit): Cast sbrk's returned value to char *.
21488 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21491 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21493 Use functions, not macros, for up- and down-casing (Bug#8254).
21494 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21495 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21496 to use the following functions instead of these macros.
21497 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21498 EMACS_INT, since callers assume the returned value fits in int.
21499 (upcase1): Likewise, for UPCASE_TABLE.
21500 (uppercasep, lowercasep, upcase): New static inline functions.
21501 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21511 (regex_compile, re_match_2_internal): Mark locals as initialized.
21512 (RETALLOC_IF): Define only if needed.
21513 (WORDCHAR_P): Likewise. This one is never needed, but is used
21514 only in a comment talking about a compiler bug, so put inside
21515 the #if 0 of that comment.
21516 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21517 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21543 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21544 New macros, so that the caller can use some names other than
21545 gcpro1, gcpro2, etc.
21546 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21548 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21549 argument, for consistency with GCPRO2_VAR, etc: it is now the
21550 prefix of the variable, not the variable itself. All uses
21552 * dired.c (directory_files_internal, file_name_completion):
21553 Rename locals to avoid shadowing.
21555 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21556 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21557 dired.c's scmp function, had undefined behavior.
21558 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21559 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21560 * buffer.h: ... to here, because these macros use current_buffer,
21561 and the new implementation with inline functions needs to have
21562 current_buffer in scope now, rather than later when the macros
21564 (downcase, upcase1): New static inline functions.
21565 (DOWNCASE, UPCASE1): Reimplement using these functions.
21566 This avoids undefined behavior in expressions like
21567 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21568 from race conditions in accessing the global variables
21569 case_temp1 and case_temp2.
21570 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21571 * lisp.h (case_temp1, case_temp2): Remove their decls.
21572 * character.h (ASCII_CHAR_P): Move from here ...
21573 * lisp.h: ... to here, so that the inline functions mentioned
21574 above can use them.
21576 * dired.c (directory_files_internal_unwind): Now static.
21578 * fileio.c (file_name_as_directory, directory_file_name):

21581 (file_name_as_directory): Use const pointers when appropriate.
21582 (Fexpand_file_name): Likewise. In particular, newdir might
21583 point at constant storage, so make it a const pointer.
21584 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21585 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21587 (Fset_file_times, Finsert_file_contents, auto_save_error):
21588 Rename locals to avoid shadowing.

21592 to avoid shadowing.
21594 * marker.c (bytepos_to_charpos): Remove; unused.
21596 * lisp.h (verify_bytepos, count_markers): New decls,
21597 so that gcc does not warn that these functions aren't declared.
21599 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21600 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21601 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21602 (copy_text): Remove unused local var.
21604 * filelock.c (within_one_second): Now static.
21605 (lock_file_1): Rename local to avoid shadowing.
21607 * buffer.c (fix_overlays_before): Mark locals as initialized.
21608 (fix_start_end_in_overlays): Likewise. This function should be
21609 simplified by using pointers-to-pointers, but that's a different
21611 (switch_to_buffer_1): Now static.
21612 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21613 (report_overlay_modification): Rename locals to avoid shadowing.
21615 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21616 Fix pointer signedness issue.
21617 (sys_subshell): Mark local as volatile if checking for lint,
21618 to suppress a gcc -Wclobbered warning that does not seem to be right.
21619 (MAXPATHLEN): Define only if needed.
21621 * process.c (serial_open, serial_configure): Move decls from here ...
21622 * systty.h: ... to here, so that they can be checked.
21624 * fns.c (get_random, seed_random): Move extern decls from here ...
21625 * lisp.h: ... to here, so that they can be checked.
21627 * sysdep.c (reset_io): Now static.
21628 (wait_for_termination_signal): Remove; unused.
21630 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
21631 (copy_keymap_item, append_key, push_text_char_description):
21633 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21634 (DENSE_TABLE_SIZE): Remove; unused.
21635 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21636 (describe_map_tree):
21637 Rename locals to avoid shadowing.
21639 * keyboard.c: Declare functions static if they are not used elsewhere.

21724 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
21725 These macros can no longer be used for assignment.
