7 (scan_sexps_forward): Record from_byte and avoid redundant
8 character to byte position calculation ...
9 (Fparse_partial_sexp): ... here. Break too long line.
11 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
13 * lisp.h (make_uninit_vector): New function.
14 * alloc.c (Fvector, Fmake_byte_code):
15 * ccl.c (Fregister_ccl_program):
16 * charset.c (Fdefine_charset_internal, define_charset_internal):

22 * indent.c (recompute_width_table):
23 * nsselect.m (clean_local_selection_data):
24 * syntax.c (init_syntax_once):
25 * w32unsubscribe.c (uniscribe_shape):
26 * window.c (Fcurrent_window_configuration):
27 * xfaces.c (Fx_family_fonts):
28 * xselect.c (selection_data_to_lisp_data): Use it.
30 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
32 * coding.c (Fdefine_coding_system_internal): Use AREF where
33 argument is known to be a vector.
34 * fns.c (Flocale_info): Likewise for ASET.
35 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
36 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
38 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
40 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
43 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
44 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
45 updateCollectionBehaviour.
47 * nsterm.m (NEW_STYLE_FS): Remove.
48 (ns_last_use_native_fullscreen): New variable.
49 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
50 (x_set_window_size): Do not take title bar and tool bar into account
51 if isFullscreen returns YES.
52 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
53 (check_native_fs): New function.
54 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
55 (ns_term_init): Remove NEW_STYLE_FS.
56 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
57 and tool bar if isFullscreen returns NO.
58 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
59 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
61 (window:willUseFullScreenPresentationOptions:): New method.

66 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
67 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
68 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
69 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
70 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
71 (syms_of_nsterm): Add ns-use-native-fullscreen.
73 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
75 * fileio.c (Qchoose_write_coding_system): Now static.
77 2013-02-04 Eli Zaretskii <eliz@gnu.org>
79 * xdisp.c (window_buffer_changed): region_showing can be negative,
80 which still means region is being displayed.
81 (redisplay_internal): Resurrect code that forced redisplay of the
82 whole window when showing region and the mark has changed. Record
83 the new mark position to allow redisplay optimizations.
84 (display_line): If it->region_beg_charpos is non-zero, set the
85 window's region_showing member to -1. (Bug#13623) (Bug#13626)
87 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
88 not bitfield of 1 bit.
90 2013-02-03 Daniel Colascione <dancol@dancol.org>
92 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
93 daemon mode works on cygw32 when Emacs is installed and not just
96 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
98 Avoid file time stamp bug on MS-Windows (Bug#13149).
99 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
100 as FAT32 doesn't update time stamps when truncating them.
101 Also, check that a file time stamp is not a multiple of 100 ns;
102 this should catch all instances of the problem on MS-Windows,
103 as its native file system resolution is 100 ns or worse, and
104 checking for a non-multiple of 100 ns should impose only a small
105 overhead on systems with ns resolution.
107 2013-02-02 Eli Zaretskii <eliz@gnu.org>
109 Avoid encoding file names on MS-Windows when they need to be run
110 through dostounix_filename.
111 * w32.c (normalize_filename): Accept an additional argument
112 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
113 downcase it even if w32-downcase-file-names is non-nil.
114 (dostounix_filename): Accept an additional argument MULTIBYTE and
115 pass it to normalize_filename.
116 (emacs_root_dir): Adjust.
118 * msdos.h (dostounix_filename): Adjust prototype.
120 * w32.h (dostounix_filename): Adjust prototype.
122 * msdos.c (dostounix_filename): Accept an additional argument and
124 (init_environment): Adjust callers of dostounix_filename.
126 * fileio.c (Ffile_name_directory, file_name_as_directory)
127 (directory_file_name, Fexpand_file_name)
128 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
130 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
132 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
133 variables, as egetenv is case-insensitive for DOS_NT.
135 * dired.c (file_name_completion): Don't call Fdirectory_file_name
136 with an encoded file name.
138 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
139 calls to dostounix_filename.
141 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
143 * unexw32.c (unexec): Adjust call to dostounix_filename.
145 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
147 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
150 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
153 * callproc.c (Fcall_process): Make sure program name in PATH and
154 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
155 is passed to exec/spawnve, which fails unless the file-name
158 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
159 even if w32-quote-process-args is nil.
161 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
163 Fix timestamp bug when write-region appends nothing (Bug#13149).
164 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
165 the file's time stamp doesn't change if Emacs happens to write nothing
166 to the file, and on a buggy file system this could cause Emacs to
167 incorrectly infer that the file system doesn't have the bug.
168 Avoid this problem by inhibiting the inference in this case.
170 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
172 * window.h (struct window): Convert base_line_number, base_line_pos
173 and column_number_displayed members from Lisp_Object to ptrdiff_t.
174 Convert region_showing member from Lisp_Object to bitfield.
175 Remove sequence_number member. Adjust comments.
176 * window.c (sequence_number): Remove.
177 (make_window): Initialize column_number_displayed.
178 * print.c (print_object): Follow the printed representation of
179 frames and print window pointer to distinguish between windows.
180 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
181 * xdisp.c (wset_base_line_number, wset_base_line_pos)
182 (wset_column_number_displayed, wset_region_showing): Remove.
183 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
184 (try_scrolling, try_cursor_movement, redisplay_window)
185 (try_window_reusing_current_matrix, try_window_id, display_line)
186 (display_mode_lines, decode_mode_spec): Adjust users.
187 * .gdbinit (pwinx): Do not print sequence_number.
189 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
191 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
192 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
193 * dired.c: Include <fcntl.h>.
194 (open_directory): New function, which uses open and fdopendir
195 rather than opendir. DOS_NT platforms still use opendir, though.
196 (directory_files_internal, file_name_completion): Use it.
197 (file_attributes): New function, with most of the old Ffile_attributes.
198 (directory_files_internal, Ffile_attributes): Use it.
199 (file_attributes, file_name_completion_stat): First arg is now fd,
200 not dir name. All uses changed. Use fstatat rather than lstat +
202 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
203 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
204 (emacs_readlinkat): New function, with much of the old
205 Ffile_symlink_p, but with an fd argument for speed.
206 It uses readlinkat rather than careadlinkatcwd, so that it
207 need not assume the working directory.
208 (Ffile_symlink_p): Use it.
209 * filelock.c (current_lock_owner): Use emacs_readlinkat
210 rather than emacs_readlink.
211 * lisp.h (emacs_readlinkat): New decl.
212 (READLINK_BUFSIZE, emacs_readlink): Remove.
213 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
214 (emacs_norealloc_allocator, emacs_readlink): Remove.
215 This stuff is moved to fileio.c.
216 * w32.c (fstatat, readlinkat): New functions.
217 (careadlinkat): Don't check that fd == AT_FDCWD.
218 (careadlinkatcwd): Remove; no longer needed.
220 2013-01-31 Glenn Morris <rgm@gnu.org>
222 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
223 (Fwrite_region): Update for new choose_write_coding_system args.
224 Move the last piece of choose_write_coding_system here. (Bug#13522)
225 (syms_of_fileio): Add choose-write-coding-system.
227 2013-01-30 Eli Zaretskii <eliz@gnu.org>
229 * w32.c (sys_open): Zero out the flags for the new file descriptor.
230 (sys_close): Zero out the flags for the file descriptor before
231 closing it. (Bug#13546)
233 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
234 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
235 CharNextExA and CharPrevExA to iterate over file names encoded in
238 * w32.c (w32_get_long_filename, init_environment, readlink):
239 Support file names encoded in DBCS codepages.
240 (readlink): Use the current file-name-coding-system, not the ANSI
241 codepage, to decode and handle targets of symlinks.
243 2013-01-28 Eli Zaretskii <eliz@gnu.org>
245 * w32.c (opendir): Now accepts a 'const char *'.
247 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
249 Remove obsolete redisplay code. See the discussion at
250 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
251 * dispnew.c (preemption_period, preemption_next_check): Remove.
252 (Vredisplay_preemption_period): Likewise.
253 (update_frame, update_single_window, update_window, update_frame_1):
254 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
255 used, following the 2012-06-22 change.
257 2013-01-25 Eli Zaretskii <eliz@gnu.org>
259 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
261 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
263 * font.c (num_fonts): Remove the leftover from old
264 debugging code. Adjust comment style here and there.
265 * insdel.c (insert_1): Remove.
266 * lisp.h (insert_1): Remove prototype.
267 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
269 2013-01-25 Eli Zaretskii <eliz@gnu.org>
271 * w32.c (max_filename_mbslen): New function.
272 (normalize_filename, readdir): Use it to detect locales where ANSI
273 encoding of file names uses a double-byte character set (DBCS).
274 If a DBCS encoding is used, advance by characters using
275 CharNextExA, instead of incrementing a 'char *' pointer. Use
276 _mbslwr instead of _strlwr. (Bug#13515)
278 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
279 request of memory reservation to 1.7GB. (Bug#13065)
281 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
283 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
284 at check_extra_latin label. (Bug#13505)
286 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
288 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
289 Avoid redundant calls to strlen.
291 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
293 Drop async_visible and async_iconified fields of struct frame.
294 This is possible because async input is gone; for details, see
295 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
296 * frame.h (struct frame): Remove async_visible and async_iconified
297 members, convert garbaged to unsigned bitfield. Adjust comments.
298 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
299 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
300 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
301 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
302 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
304 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
305 properly. Likewise for obscured.
307 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
310 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
312 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
314 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
315 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
317 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
319 * xdisp.c (message2, message2_nolog): Remove functions.
320 (message3, message3_nolog): Extract nbytes and multibyteness directly
321 from the string. Change all callers.
322 (message3_nolog): Don't set message_enable_multibyte since set_message
323 will reset it anyway.
324 (message1, message1_nolog): Use message3.
325 (vmessage): Use a stack allocated buffer rather than f->message_buf.
326 (with_echo_area_buffer): Remove last two arguments. Update all callers.
327 (set_message): Drop all but the second arg, which has to be a string.
328 (set_message_1): Simplify now that we know that a1 is NULL and the
329 second arg is a string.
330 * frame.h (struct frame): Remove `message_buf' field.
331 Use glyphs_initialized_p instead.
332 (FRAME_MESSAGE_BUF): Remove macro.
333 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
334 * lisp.h (message2, message2_nolog): Remove declarations.
335 (message3, message3_nolog): Update declarations.
336 * keyboard.c (read_char_minibuf_menu_text)
337 (read_char_minibuf_menu_width): Remove vars.
338 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
339 to correctly handle multibyte strings.
340 * frame.c (delete_frame): Don't free message_buf any more.
341 * editfns.c (message_text, message_length): Remove vars.
342 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
343 * fileio.c (auto_save_error): Use message3 instead of message2.
344 * dispnew.c (adjust_frame_message_buffer): Remove function.
346 2013-01-23 Eli Zaretskii <eliz@gnu.org>
348 * w32term.c (w32fullscreen_hook): Account correctly for the screen
349 real estate used for the tool bar and the menu bar.
351 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
353 * insdel.c (prepare_to_modify_buffer): Force redisplay if
354 hidden buffer is prepared to modification (Bug#13164).
356 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
358 * window.h (struct window): Change window_end_valid member from
359 Lisp_Object to a bitfield. Adjust comments.
360 (wset_window_end_valid): Remove.
361 * window.c (adjust_window_count): Clear window_end_valid.
362 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
363 (Fwindow_line_height, set_window_buffer, Frecenter)
364 (Fsplit_window_internal, Fdelete_other_windows_internal)
365 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
366 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
367 * xdisp.c (check_window_end, reconsider_clip_changes)
368 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
369 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
370 (find_first_unchanged_at_end_row, try_window_id): Likewise.
372 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
374 * xdisp.c (mark_window_display_accurate): Simplify the loop
375 assuming that the only one of vchild, hchild or buffer window
376 slots is non-nil. Call mark_window_display_accurate_1 for
377 the leaf windows only.
378 (mark_window_display_accurate_1): Always assume leaf window.
381 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
383 * emacs.c (Qkill_emacs_hook): Now static.
385 * fileio.c (Finsert_file_contents): Simplify.
386 Remove unnecessary assignments and tests.
388 2013-01-21 Eli Zaretskii <eliz@gnu.org>
390 * w32.c (acl_set_file): Don't test for errors unless
391 set_file_security returns FALSE. Avoids spurious errors when
394 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
396 * fileio.c (Finsert_file_contents): Revert code introduced at
397 2013-01-18 in favor of the simpler and generally better fix.
398 Save stack space by removing 'buffer' and reusing 'read_buf'
401 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
403 * lisp.h (eabs): Define unconditionally (Bug#13419).
404 The old "#if !defined (eabs)" was an unnecessary revenant of back
405 when this macro was called "abs". Document 'eabs' better.
407 2013-01-19 Glenn Morris <rgm@gnu.org>
409 * fns.c (Frandom): Doc fix.
411 2013-01-19 Eli Zaretskii <eliz@gnu.org>
413 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
414 segfault when there are lots of overlays.
416 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
417 when there are lots of overlays. See
418 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
419 for the details and a way to reproduce.
421 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
423 * fileio.c: Use O_APPEND to append.
424 This corresponds better to the natural interpretation of "append",
425 and avoids the need to open the output file twice, or to invoke
426 lseek when APPEND is neither nil nor a number.
427 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
428 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
429 file possibly twice, and lseeking to its end; this avoids the
430 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
431 at the same time: the combination is never needed and apparently
432 it doesn't work with DOS_NT.
434 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
435 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
437 Allow floating-point file offsets.
438 Problem reported by Vitalie Spinu in
439 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
440 * fileio.c (emacs_lseek): Remove.
441 (file_offset): New function.
442 (Finsert_file_contents, Fwrite_region): Use it.
444 2013-01-19 Chong Yidong <cyd@gnu.org>
446 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
447 aborting on Fsignal (Bug#13289).
449 2013-01-19 Eli Zaretskii <eliz@gnu.org>
451 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
452 set_file_security as failure due to insufficient privileges.
453 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
454 (fstat): Return owner and group like 'stat' and 'lstat' do.
456 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
458 Work around bug in CIFS and vboxsf file systems (Bug#13149).
459 The bug was observed on Ubuntu operating inside a virtual machine,
460 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
461 The workaround introduces a race condition on non-buggy hosts,
462 but it's an unlikely race and anyway there's a nearly identical
463 nearby race that can't be fixed.
464 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
466 (Fwrite_region): Test for file system time stamp bug.
467 (init_fileio): New function.
468 * lisp.h (init_fileio): Declare it.
469 * emacs.c (main): Call it.
471 * fileio.c (Finsert_file_contents): Simplify new diagnostic
472 and make it more consistent with other stat-failure diagnostics.

476 Fix crash when inserting data from non-regular files. See
477 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
478 for the error description produced by valgrind.
479 * fileio.c (read_non_regular): Rename to read_contents.
480 Free Lisp_Save_Value object used to pass parameters.
481 (read_non_regular_quit): Rename to read_contents_quit.
482 (Finsert_file_contents): Redesign internal file reading loop to adjust
483 gap and end positions after each read and so help make_gap to work
484 properly. Do not signal an I/O error too early and so do not leave
485 not yet decoded characters in a buffer, which was the reason of
486 redisplay crash. Use list2 to build return value. Adjust comments.
488 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
490 Close a race when statting and reading files (Bug#13149).
491 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
492 This avoids a race if the file is renamed between stat and open.
493 This race is not the problem originally noted in Bug#13149;
494 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

946 * w32.c (acl_set_file): If setting the file security descriptor
947 fails, and the new DACL is identical to the existing one, silently

956 thread shutdown when delete_child triggers it.
957 (reap_subprocess): More accurate commentary for why we call
958 delete_child only when cp->fd is negative.
960 * w32.c (sys_close): Do not call delete_child on a subprocess
961 whose handle is not yet closed. Instead, set its file descriptor
962 to a negative value, so that reap_subprocess will call
963 delete_child on that subprocess when its SIGCHLD arrives.
964 This avoids closing handles used for communications between sys_select
965 and reader_thread, which doesn't give sys_select a chance to
966 notice that the process exited and invoke the SIGCHLD handler for
969 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
971 * nsfns.m (Fns_do_applescript): Run event loop until script has

982 * w32term.c (w32fullscreen_hook): New function.
983 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
985 2012-12-21 Eli Zaretskii <eliz@gnu.org>
987 * fileio.c (Finsert_file_contents): Doc fix.
989 * w32proc.c (new_child, delete_child, find_child_pid): For a
990 subprocess, consider its slot being in use as long as its process
991 handle (procinfo.hProcess) is not NULL. This avoids reusing the
992 slot when a new process is started immediately after killing
993 another one, without waiting enough time for the first process to
994 be reaped and resources allocated for it be orderly freed.
996 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
998 2012-12-21 Chong Yidong <cyd@gnu.org>

1004 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1006 * w32.c (get_name_and_id): Always pass NULL as the first argument
1007 of lookup_account_sid. Avoids crashes with UNC file names that
1008 refer to DFS domains, not to specific machine names. (Bug#12621)
1009 Remove now unused argument FNAME; all callers changed.
1010 (get_file_owner_and_group): Remove now unused argument FNAME; all
1013 2012-12-21 Chong Yidong <cyd@gnu.org>
1015 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1016 error for invalid chars, don't check for a nil return value.
1018 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1020 Avoid calls to CHAR_TO_BYTE if byte position is known.
1021 * editfns.c (make_buffer_string_both): Use move_gap_both.

1026 (charpos_to_bytepos): Remove.
1027 * fileio.c (Finsert_file_contents): Use move_gap_both.
1028 * search.c (Freplace_match): Likewise.

1042 (redisplay_internal): Don't bother selecting the frame to get the
1043 proper value of frame-local variables (bug#13225).
1045 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1047 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1048 Rename 4th argument since it may be buffer or string. Adjust comment.
1049 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1051 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1053 * coding.c (Fdetect_coding_region): Do not check start and end with
1054 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1055 (code_convert_region): Likewise.
1057 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1059 * w32.c (acl_get_file, acl_set_file): Run the file name through
1060 map_w32_filename, and resolve any symlinks in the file name, like
1062 (acl_set_file): Call revert_to_self, if any privileges were

1072 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1073 propagate redisplay's scrolling (if any) to the right window.
1074 (redisplay_internal): Use ensure_selected_frame.
1075 (display_mode_lines): Complete last fix.
1076 * window.c (select_window_1): New func, extracted from select_window.
1077 (select_window): Use it.
1078 * window.h (select_window_1): Declare.

1104 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1106 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1107 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1108 for some of that bug's symptoms can now cause Emacs to abort.
1109 Remove the workaround.
1110 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1111 The bug that caused SIGCHLD to get lost has been fixed, and the
1112 workaround for it can now cause Emacs to abort.
1114 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1116 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1117 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1118 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1120 2012-12-16 Romain Francoise <romain@orebokech.com>
1122 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1123 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1124 and copy ACL entries of file in addition to SELinux context if set.
1125 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1127 * Makefile.in (LIBACL_LIBS): New macro.

1142 * w32proc.c (new_child): Initialize input_file and
1143 pending_deletion members of the child.
1144 (delete_child): Delete the child's temporary input file, if any,
1145 that is pending deletion.
1146 (register_child): First argument is now pid_t.
1147 (record_infile, record_pending_deletion): New functions.
1148 (reap_subprocess): Fix a typo in DebPrint string.
1149 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1151 * fileio.c (internal_delete_file): Return an int again: non-zero
1152 if delete-file succeeds, zero otherwise.
1154 * lisp.h (internal_delete_file): Adjust prototype.
1156 * callproc.c (Fcall_process): Don't overwrite infile with result
1158 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1159 asynchronous subprocess, record the name of the input file name,
1161 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1162 delete the file, record it as pending deletion when the subprocess
1165 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1167 * editfns.c [HAVE_PWD_H]: Include grp.h.
1169 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

1173 Fix permissions bugs with setgid directories etc. (Bug#13125)
1174 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1175 to mark it as a placeholder. The old value was often wrong.

1177 file-ownership-preserved-p instead, with its new group arg.
1178 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1180 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

1185 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1187 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1188 try to get accurate owner and group information from NT file
1189 security APIs. This is to make most callers of 'stat' and
1190 'lstat', which don't need that information, much faster.
1192 * dired.c (Ffile_attributes) [WINDOWSNT]:
1193 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1194 owner and group information from 'lstat'.
1196 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1198 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1199 as that confuses set-auto-coding, so insist on the head-read
1200 returning the full 1024 bytes. Let lseek compute the tail offset;
1201 less work for us. Do not ignore I/O errors when reading the tail.
1203 * xdisp.c: Minor style fixes.
1204 (init_iterator): Hoist assignment out of if-expression.
1205 (markpos_of_region): Callers now test for sign, not for -1.

1218 * search.c (search_buffer): Check the inverse translations of each
1219 character in pattern when the buffer being searched is unibyte.
1222 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1224 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1225 files, fixing a regression from 24.2.
1226 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1228 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1230 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1231 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1232 Remove unnecessary S_ISLNK test, as (contra the comments) this
1233 function can't copy symlinks. Improve quality of error message
1234 when attempting to copy files that are neither regular files nor

1242 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1243 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1245 2012-12-12 Daniel Colascione <dancol@dancol.org>
1247 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1248 the dumped Emacs is not a sparse file, greatly improving Cygwin
1249 "make bootstrap" performance.
1251 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1253 * inotify.c (inotify_callback): Generate an Emacs event for every
1254 incoming inotify event.
1256 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1258 * xdisp.c (handle_face_prop): Fix logic of computing
1259 it->start_of_box_run_p.
1260 (append_space_for_newline): If the glyph row is R2L, reset the
1261 iterator's end_of_box_run_p flag before prepending the space glyph.
1262 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1263 iterator's start_of_box_run_p flag before prepending the stretch.
1264 (append_glyph, produce_image_glyph, append_composite_glyph)
1265 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1266 left_box_line_p and right_box_line_p flags of the glyph for R2L
1267 glyph rows. (Bug#13011)
1269 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1282 encoded_file_name, which is what it is.
1284 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1316 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1317 (hinst): Remove unneeded extern declaration.
1318 (_start): Remove initialization of above variables; remove

1440 2012-12-10 Christopher Schmidt <christopher@ch.ristopher.com>
1442 * lread.c (Vload_source_file_function): Doc fix (Bug#11647).
1444 2012-12-10 Eli Zaretskii <eliz@gnu.org>
1446 * indent.c (Fvertical_motion): If a display string will be
1447 displayed on the left or the right margin, don't consider it as a
1448 factor in cursor positioning. (Bug#13108)
1450 2012-12-10 Martin Rudalics <rudalics@gmx.at>
1452 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
1454 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>
1456 * fileio.c (Fsubstitute_in_file_name): Use ptrdiff_t, not int,
1459 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1461 * w32.c (unsetenv): Return 0 if the input string is too long.
1463 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1465 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1466 * alloc.c (xputenv): New function.
1467 * dbusbind.c (Fdbus_init_bus):
1469 * xterm.c (x_term_init):
1470 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1471 * editfns.c (initial_tz): Move static var decl up.
1472 (tzvalbuf_in_environ): New static var.
1473 (init_editfns): Initialize these two static vars.
1474 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1475 Save old TZ value on stack, if it's small.
1476 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1477 instead, use xputenv+unsetenv to set and restore TZ.
1478 (environbuf): Remove static var. All uses removed.
1479 (Fset_time_zone_rule): Do not save TZ and environ;
1480 no longer needed here.
1481 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1482 Move to inside set_time_zone_rule; they don't need file scope any more.
1483 (set_time_zone_rule): Maintain the TZ=value string separately.
1484 (syms_of_editfns): Don't initialize initial_tz;
1485 init_editfns now does it.
1486 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1487 * lisp.h (xputenv): New decl.
1489 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1491 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1493 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1495 * w32.c (unsetenv, sys_putenv): New functions.
1497 2012-12-08 Chong Yidong <cyd@gnu.org>
1499 * editfns.c (Finsert_char): Make the error message more
1500 informative (Bug#12992).
1502 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1504 Simplify get_lim_data.
1505 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1506 Remove USG and vlimit methods; no longer used these days.
1507 Add #error catchall just in case.
1509 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1510 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1511 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1512 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1513 (deleted_pid_list, Fdelete_process, create_process)
1514 (record_child_status_change, handle_child_signal, deliver_child_signal)
1515 (init_process_emacs, syms_of_process):
1516 Assume SIGCHLD is defined.
1517 (parse_signal): Remove. All uses removed.
1518 (abbr_to_signal): New static function.
1519 (Fsignal_process): Use it to convert signal names to ints.
1520 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1521 kill (getpgrp (), ...).
1522 (emacs_sigaction_init): Assume SIGCHLD is defined.
1523 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1524 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1525 * syssignal.h (EMACS_KILLPG): Remove.
1526 All uses replaced by 'kill' with a negative pid.
1527 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1528 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1530 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1532 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1533 This will cause a production Emacs to dump core instead of
1536 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1538 * frame.c (make_frame): Do not set window's buffer to t.
1539 * window.c (Fsplit_window_internal): Likewise. Previously it was
1540 used to indicate that the window is being set up. Now we use
1541 set_window_buffer for all new windows, so the condition in ...
1542 (Fset_window_buffer): ... is always true and can be removed.
1544 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1546 Convenient macro to check whether the buffer is hidden.
1547 * buffer.h (BUFFER_HIDDEN_P): New macro.
1548 * frame.c (make_frame): Use it. Adjust comment.
1549 * buffer.c (candidate_buffer): New function.
1550 (Fother_buffer, other_buffer_safely): Use it.
1552 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1554 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1555 if the child process is still running. Instead, exit the wait
1556 loop and return zero. (Bug#13086)
1558 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1560 * frame.h (x_char_width, x_char_height): Remove prototypes.
1561 * w32term.h (x_char_width, x_char_height): Likewise.
1562 * xfns.c (x_char_width, x_char_height): Remove.
1563 * w32fns.c (x_char_width, x_char_height): Likewise.
1564 * nsfns.c (x_char_width, x_char_height): Likewise.
1565 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
1567 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
1568 * keyboard.c (command_loop_1): Remove prototype.

1571 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1573 Fix a recently-introduced delete-process race condition.
1574 * callproc.c, process.h (record_kill_process):
1575 New function, containing part of the old call_process_kill.
1576 (call_process_kill): Use it.
1577 This does not change call_process_kill's behavior.
1578 * process.c (Fdelete_process): Use record_kill_process to fix a
1579 race condition that could cause Emacs to lose track of a child.
1581 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1583 Avoid code duplication between prev_frame and next_frame.
1584 * frame.c (candidate_frame): New function. Add comment.
1585 (prev_frame, next_frame): Use it. Adjust comment.
1587 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1589 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1590 fails, signal an error instead of continuing with an empty
1592 Encode expanded temp file pattern before passing it to mkstemp or
1595 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1596 Encode the file name before passing it to dostounix_filename, in
1597 case it will downcase it (under w32-downcase-file-names).
1600 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1602 Minor call-process cleanups.
1603 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1604 at the same time as other platforms, to simplify analysis.
1605 No need for fd0_volatile since we have synch_process_fd.
1606 Avoid needless emacs_close; arg is always negative.
1608 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1610 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1613 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1615 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1616 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1617 and mouse_face_hidden members to a bitfields.
1618 * frame.h (struct frame): Remove set-but-not-used space_width member.
1619 (FRAME_SPACE_WIDTH): Remove.
1620 * nsterm.m, w32term.c, xterm.c: Adjust users.
1621 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1622 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1623 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1624 members to a bitfields.
1626 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1628 Don't let call-process be a zombie factory (Bug#12980).
1629 Fixing this bug required some cleanup of the signal-handling code.
1630 As a side effect, this change also fixes a longstanding rare race
1631 condition whereby Emacs could mistakenly kill unrelated processes,
1632 and it fixes a bug where a second C-g does not kill a recalcitrant
1633 synchronous process in GNU/Linux and similar platforms.
1634 The patch should also fix the last vestiges of Bug#9488,
1635 a bug which has mostly been fixed on the trunk by other changes.
1636 * callproc.c, process.h (synch_process_alive, synch_process_death)
1637 (synch_process_termsig, sync_process_retcode):
1638 Remove. All uses removed, to simplify analysis and so that
1639 less consing is done inside critical sections.
1640 * callproc.c (call_process_exited): Remove. All uses replaced
1641 with !synch_process_pid.
1642 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1643 These take the role of what used to be in unwind-protect arg.
1645 (block_child_signal, unblock_child_signal):
1646 New functions, to avoid races that could kill innocent-victim processes.
1647 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1648 (call_process_kill): Record killed processes as deleted, so that
1649 zombies do not clutter up the system. Do this inside a critical
1650 section, to avoid a race that would allow the clutter.
1651 (call_process_cleanup): Fix code so that the second C-g works again
1652 on common platforms such as GNU/Linux.
1653 (Fcall_process): Create the child process in a critical section,
1654 to fix a race condition. If creating an asynchronous process,
1655 record it as deleted so that zombies do not clutter up the system.
1656 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1657 light of these changes. Omit unnecessary call to emacs_close
1658 before failure, as the unwind-protect code does that.
1659 * callproc.c (call_process_cleanup):
1660 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1661 * process.c (record_deleted_pid): New function, containing
1662 code refactored out of Fdelete_process.
1663 (Fdelete_process): Use it.
1664 (process_status_retrieved): Remove. All callers changed to use
1665 child_status_change.
1666 (record_child_status_change): Remove, folding its contents into ...
1667 (handle_child_signal): ... this signal handler. Now, this
1668 function is purely a handler for SIGCHLD, and is not called after
1669 a synchronous waitpid returns; the synchronous code is moved to
1670 wait_for_termination. There is no need to worry about reaping
1671 more than one child now.
1672 * sysdep.c (get_child_status, child_status_changed): New functions.
1673 (wait_for_termination): Now takes int * status and bool
1674 interruptible arguments, too. Do not record child status change;
1675 that's now the caller's responsibility. All callers changed.
1676 Reimplement in terms of get_child_status.
1677 (wait_for_termination_1, interruptible_wait_for_termination):
1678 Remove. All callers changed to use wait_for_termination.
1679 * syswait.h: Include <stdbool.h>, for bool.
1680 (record_child_status_change, interruptible_wait_for_termination):
1682 (record_deleted_pid, child_status_changed): New decls.
1683 (wait_for_termination): Adjust to API changes noted above.
1685 * bytecode.c, lisp.h (Qbytecode): Remove.
1686 No longer needed after 2012-11-20 interactive-p changes.
1688 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1690 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1691 the scroll margin, move point outside the margin. (Bug#13055)
1693 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1695 * gtkutil.c (my_log_handler): New function.
1696 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1698 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1700 * lisp.h (modify_region): Rename to...
1701 (modify_region_1): ...new prototype.
1702 * textprop.c (modify_region): Now static. Adjust users.
1703 * insdel.c (modify_region): Rename to...
1704 (modify_region_1): ...new function to work with current buffer.
1705 Adjust comment and users. Use true and false for booleans.
1707 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1709 * alloc.c (free_save_value): New function.
1710 (safe_alloca_unwind): Use it.
1711 * lisp.h (free_save_value): New prototype.
1712 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1714 (save_excursion_restore): Adjust to match saved data structure.
1715 Use free_save_value to offload some work from GC. Drop obsolete
1718 2012-12-03 Chong Yidong <cyd@gnu.org>
1720 * fileio.c (Vauto_save_list_file_name): Doc fix.
1722 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1724 * w32fns.c: Remove prototype of atof.
1725 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1727 (file_dialog_callback): Make it UINT_PTR.
1729 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1732 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1733 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1736 2012-12-03 Glenn Morris <rgm@gnu.org>
1738 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1740 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1742 Fix xpalloc confusion after memory is exhausted.
1743 * alloc.c (xpalloc): Comment fix.
1744 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1745 and signals an error, do not clear charset_table_size, as
1746 charset_table is still valid.
1747 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1749 Use execve to avoid need to munge environ (Bug#13054).
1750 * callproc.c (Fcall_process):
1751 * process.c (create_process):
1752 Don't save and restore environ; no longer needed.
1753 * callproc.c (child_setup):
1754 Use execve, not execvp, to preserve environ.
1756 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1758 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1760 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1762 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1763 display for sliced images (Bug#10500).
1765 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1767 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1769 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1770 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1772 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1774 * xdisp.c (window_outdated): Remove eassert since it hits
1775 some suspicious corner cases (see Bug#13007 and Bug#13012).
1776 (mode_line_update_needed): New function.
1777 (redisplay_internal, redisplay_window): Use it.
1778 (ensure_selected_frame): New function.
1779 (redisplay_internal, unwind_redisplay): Use it.
1780 (redisplay_internal): Move comment about buffer_shared...
1781 (buffer_shared_and_changed): ...near to its real use.
1783 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1785 * callproc.c (Fcall_process): Don't misreport vfork failure.
1787 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1789 * callproc.c (Fcall_process): Fix vfork portability problems.
1790 Do not assume that fd[0], count, filefd, and save_environ survive
1791 vfork. Fix bug whereby wrong errno value could be reported for
1792 pipe failure. Some minor cleanups, too, as follows. Move buf and
1793 bufsize to the context where they're needed. Change new_argv to
1794 be of type char **, as this is more convenient and avoids casts.
1795 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1796 Now local constants, not macros.
1798 2012-11-18 Kenichi Handa <handa@gnu.org>
1800 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1801 for the variable "f".
1803 2012-11-13 Kenichi Handa <handa@gnu.org>
1805 * font.c (font_unparse_xlfd): Exclude special characters from the
1806 generating XLFD name.
1808 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1810 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1812 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1814 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1816 Assume EAGAIN and EINTR are defined.
1818 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1819 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1820 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1821 * lread.c (readbyte_from_file): Assume EINTR is defined.
1822 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1823 Assume EIO and EAGAIN are defined.
1824 * unexcoff.c (write_segment): Assume EFAULT is defined.
1826 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1828 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1831 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1832 highlighting on the frame was cleared. Prevents assertion
1833 violations when repeatedly clicking on the "Top" link of the
1834 "bread-crumbs" in Info buffers.
1836 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1838 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1840 2012-11-24 Ken Brown <kbrown@cornell.edu>
1842 * keyboard.c (HAVE_MOUSE):
1843 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1844 were always defined.
1846 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1848 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1849 between bpos_covered and bpos_max. This fixes cursor display when
1850 several display strings follow each other.
1852 * .gdbinit (pgx): If the glyph's object is a string, display the
1853 pointer to string data, rather than the value of the string object
1854 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1856 * indent.c (Fvertical_motion): If the starting position is covered
1857 by a display string, return to one position before that, to avoid
1858 overshooting it inside move_it_to. (Bug#12930)
1860 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1862 * frame.h (struct frame): Remove display_preempted member
1863 since all users are dead long ago.

1865 * w32menu.c (pending_menu_activation): Remove since not
1867 (set_frame_menubar): Adjust user.
1868 * w32term.h (struct x_output): Drop outdated #if 0 code.
1869 (struct w32_output): Use bitfields for explicit_parent,
1870 asked_for_visible and menubar_active members.
1871 Drop unused pending_menu_activation member.
1872 * xterm.h (struct x_output): Drop outdated #if 0 code.
1873 Use bitfields for explicit_parent, asked_for_visible,
1874 has_been_visible and net_wm_state_hidden_seen members.
1876 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1878 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1879 of a literal "/". (Bug#12955)
1880 (gl-stamp): Invoke fc.exe directly, not through cmd.
1882 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1884 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1885 * dired.c: Assume HAVE_DIRENT_H.
1886 (NAMLEN): Remove, replacing with ...
1887 (dirent_namelen): New function. All uses changed. Use the GNU macro
1888 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1889 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1890 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1891 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1893 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1894 * ndir.h: Rename to ../nt/inc/dirent.h.
1895 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1896 Do not include <dirent.h>; no longer needed.
1897 * w32.c: Include <dirent.h> rather than "ndir.h".
1899 2012-11-23 Chong Yidong <cyd@gnu.org>
1901 * xftfont.c (xftfont_open): Remove duplicate assignment.
1903 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1905 * alloc.c (Fgarbage_collect): Unblock input after clearing
1906 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1907 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1908 * msdos.c (IT_frame_up_to_date): Use it here...
1909 * w32term.c (w32_frame_up_to_date): ...here...
1910 * xterm.c (XTframe_up_to_date): ...and here...
1911 * nsterm.m (ns_frame_up_to_date): ...but not here.
1912 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1914 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1915 Do not check whether GC is in progress.
1917 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1919 * xdisp.c (window_buffer_changed): New function.
1920 (update_menu_bar, update_tool_bar): Use it to
1921 simplify large 'if' statements.

1923 'tail' and 'frame' local variables.
1925 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1927 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1928 with Windows system header.
1930 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1932 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1933 * alloc.c: Assume unistd.h exists.
1934 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1935 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1936 (getwd) [USG]: Remove; no longer needed.
1937 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1938 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1939 * w32.h (getcwd): Remove decl.
1941 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1943 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1944 Make it set selected_window as well.
1945 (update_tool_bar): Use it.
1947 2012-11-21 Ken Brown <kbrown@cornell.edu>
1949 * emacs.c (main): Set the G_SLICE environment variable for all
1950 Cygwin builds, not just GTK builds. See
1951 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1953 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1955 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1956 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1957 Define for the MSVC compiler.
1959 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1961 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1962 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1963 dostounix_filename. Prevents crashes down the road, because
1964 dostounix_filename assumes it gets a unibyte string.
1965 Reported by Michel de Ruiter <michel@sentient.nl>, see
1966 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1968 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1972 * lread.c (init_obarray): Set `function' fields to Qnil.
1973 * eval.c (Fcommandp): Ignore Qunbound.
1974 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1975 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1976 Test NILP rather than Qunbound.
1977 (Ffmakunbound): Set to Qnil.
1978 (Fsymbol_function): Never signal an error.
1979 (Finteractive_form): Ignore Qunbound.
1981 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1983 * eval.c (interactive_p): Remove no-longer-used decl.
1985 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1987 * xdisp.c (buffer_shared): Adjust comment.
1988 (buffer_shared_and_changed): New function.
1989 (prepare_menu_bars, redisplay_internal): Use it to
1990 decide whether all windows or frames should be updated.
1991 (window_outdated): New function.
1992 (text_outside_line_unchanged_p, redisplay_window): Use it.
1993 (redisplay_internal): Likewise. Fix indentation.
1995 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1997 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1998 (syms_of_eval): Remove corresponding defsubr.
1999 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2001 2012-11-19 Daniel Colascione <dancol@dancol.org>
2003 * w32fns.c (Fx_file_dialog):
2004 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2005 cygwin_convert_file_name*.
2007 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2008 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2010 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2012 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2014 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2016 * w32select.c: Include w32common.h before w32term.h, so that
2017 windows.h gets included before w32term.h uses some of its
2018 features, see below.
2020 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2022 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2024 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2026 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2028 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2029 (ns_select): Return at once if events are held (Bug#12834).
2031 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2033 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2034 Needed following 2012-10-20 change. (Bug#12902)
2036 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2038 * w32proc.c (waitpid): Remove unused label get_result.
2040 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2042 * makefile.w32-in (SYSWAIT_H): New macro.
2043 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2044 ($(BLD)/sysdep.$(O)): Update dependencies.
2046 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2048 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2049 * callproc.c (relocate_fd): Assume F_DUPFD.
2050 * emacs.c, term.c (O_RDWR): Remove.
2051 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2052 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2053 * nsterm.m: Assume <fcntl.h> exists.
2054 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2055 (create_pty, Fmake_network_process, server_accept_connection)
2056 (wait_reading_process_output, init_process_emacs):
2058 (wait_reading_process_output): Put in a special case for WINDOWSNT
2059 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2060 It's not clear this is needed, but it's a more-conservative change.
2061 (create_process): Assume FD_CLOEXEC.
2062 (create_process, create_pty): Assume O_NOCTTY.
2063 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2064 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2065 Omit if not DOS_NT, since F_GETFL is not defined there.
2066 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2067 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2069 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2070 lack it, since gnulib guarantees this.
2071 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2073 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2075 * w32.c (faccessat): Pretend that directories have the execute bit
2076 set. Emacs expects that, e.g., in files.el:cd-absolute.
2078 * w32proc.c (create_child): Don't clip the PID of the child
2079 process to fit into an Emacs integer, as this is no longer a
2081 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2082 reaping only the process specified by PID argument, if that is
2083 positive. Use PID instead of dead_child to know which process to
2084 reap. Wait for the child to die only if WNOHANG is not in
2086 (sys_select): Don't set dead_child.
2088 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2089 as it is no longer needed.
2091 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2093 (record_child_status_change): Remove the setting of
2094 record_at_most_one_child for the !WNOHANG case.
2096 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2098 Fix problems in ns port found by static checking.
2099 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2100 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2101 not to process group.
2102 (ns_select): Use emacs_write, not write, as that's more robust
2103 in the presence of signals.
2104 (fd_handler:): Check for read errors.
2106 2012-11-16 Glenn Morris <rgm@gnu.org>
2108 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2110 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2112 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2114 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2116 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2117 use the same value of thread handle.
2118 (start_timer_thread): If the timer thread exited (due to error),
2119 clean up by closing the two handles it used. Duplicate the caller
2120 thread's handle here, so it gets duplicated only once, when
2121 launching the timer thread. Set priority of the timer thread, not
2123 (getitimer): Don't duplicate the caller thread's handle here.
2126 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2128 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2131 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2133 Remove no-longer-used pty_max_bytes variable.
2134 * process.c (pty_max_bytes): Remove; unused.
2135 (send_process): Do not set it.
2137 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2139 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2140 Update dependencies.
2142 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2144 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2145 This follows up on the 2012-09-29 patch that removed indirection
2146 for the 'function' field. Reported by Sergey Vinokurov in
2147 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2149 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2151 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2152 different name, as the MS runtime does not have such a function,
2153 and probably never will.) All callers changed. Ignore DIRFD
2154 value if PATH is an absolute file name, to match Posix spec
2155 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2158 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2160 * xdisp.c (echo_area_display, redisplay_internal):
2161 Omit redundant check whether frame_garbaged is set.
2163 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2165 Use faccessat, not access, when checking file permissions (Bug#12632).
2166 This fixes a bug that has been present in Emacs since its creation.
2167 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2168 which must set some sort of record. (Torek's bug report was against
2169 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2170 same common flaw.) See Torek's Usenet posting
2171 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2172 Posted: Fri Apr 8 14:18:56 1983.
2173 * Makefile.in (LIB_EACCESS): New macro.
2175 * callproc.c (init_callproc):
2176 * charset.c (init_charset):
2177 * fileio.c (check_existing, check_executable, check_writable)
2179 * lread.c (openp, load_path_check):
2180 * process.c (allocate_pty):
2182 Use effective UID when checking permissions, not real UID.
2183 * callproc.c (init_callproc):
2184 * charset.c (init_charset):
2185 * lread.c (load_path_check, init_lread):
2186 Test whether directories are accessible, not merely whether they exist.
2187 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2188 * fileio.c (check_existing, check_executable, check_writable)
2190 Use symbolic names instead of integers for the flags, as they're
2192 (check_writable): New arg AMODE. All uses changed.
2193 Set errno on failure.
2194 (Ffile_readable_p): Use faccessat, not stat + open + close.
2195 (Ffile_writable_p): No need to call check_existing + check_writable.
2196 Just call check_writable and then look at errno. This saves a syscall.
2197 dir should never be nil; replace an unnecessary runtime check
2198 with an eassert. When checking the parent directory of a nonexistent
2199 file, check that the directory is searchable as well as writable, as
2200 we can't create files in unsearchable directories.
2201 (file_directory_p): New function, which uses 'stat' on most platforms
2202 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2203 (Ffile_directory_p, Fset_file_times): Use it.
2204 (file_accessible_directory_p): New function, which uses a single
2205 syscall for efficiency.
2206 (Ffile_accessible_directory_p): Use it.
2207 * xrdb.c (file_p): Use file_directory_p.
2208 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2209 * lread.c (openp): When opening a file, use fstat rather than
2210 stat, as that avoids a permissions race. When not opening a file,
2211 use file_directory_p rather than stat.
2212 (dir_warning): First arg is now a usage string, not a format.
2213 Use errno. All uses changed.
2214 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2215 that merely introduced a race.
2216 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2217 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2218 and similarly for the other O_* flags.
2219 * w32.c (sys_faccessat): Rename from sys_access and switch to
2220 faccessat's API. All uses changed.
2221 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2222 (magic_db): Rename from magic_file_p.
2223 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2224 char *, so that we don't have to test for file existence
2225 separately from opening the file for reading. This removes a race
2226 fixes a permission-checking problem, and simplifies the code.
2228 (file_p): Remove; no longer needed.
2230 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2232 Omit glyphs initialization at startup.
2233 * dispnew.c (glyphs_initialized_initially_p): Remove.
2234 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2235 (Fredraw_frame): Move actual code from here...
2236 (redraw_frame): ...to here. Add eassert. Adjust comment.
2237 (Fredraw_display): Use redraw_frame.
2238 * xdisp.c (clear_garbaged_frames): Likewise.
2240 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2242 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2243 passed to pint2str and pint2hrstr to be at most the size of the
2244 frame's decode_mode_spec_buffer. This avoids crashes with very
2245 large values of FIELD_WIDTH argument to decode_mode_spec.
2248 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2250 Fix a race with verify-visited-file-modtime (Bug#12863).
2251 Since at least 1991 Emacs has ignored an mtime difference of no
2252 more than one second, but my guess is that this was to work around
2253 file system bugs that were fixed long ago. Since the race is
2254 causing problems now, let's remove that code.
2255 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2256 whose time stamp is off by no more than a second. Insist that the
2257 file time stamps match exactly.
2259 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2261 * frame.h (struct frame): Convert external_tool_bar member to
2262 1-bit unsigned bitfield.
2263 * termhooks.h (struct terminal): Remove mouse_moved member since
2264 all users are long dead. Adjust comment on mouse_position_hook.
2266 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2268 Simplify by using FOR_EACH_FRAME here and there.
2269 * frame.c (next_frame, prev_frame, other_visible_frames)
2270 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2271 * w32term.c (x_window_to_scroll_bar): Likewise.
2272 * window.c (window_list): Likewise.
2273 * xdisp.c (x_consider_frame_title): Likewise.
2274 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2275 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2276 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2277 * xmenu.c (menubar_id_to_frame): Likewise.
2278 * xselect.c (frame_for_x_selection): Likewise.
2279 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2280 (x_window_to_menu_bar): Likewise.
2281 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2283 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2285 * data.c (Qdefalias_fset_function): Now static.
2287 Another tweak to vectorlike_header change.
2288 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2289 Remove, and replace all uses with ...
2290 (next_in_free_list, set_next_in_free_list):
2291 New functions, which respect C's aliasing rules better.
2293 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2295 * window.c (list4i): Rename from 'quad'. All uses changed.
2296 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2298 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2300 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2301 warning about mixing declarations and code in ISO C90.
2303 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2305 * window.c (Fsplit_window_internal): Set combination limit of
2306 new parent window to t iff Vwindow_combination_limit is t;
2307 fixing a regression introduced with the change from 2012-09-22.
2308 (Fset_window_combination_limit): Fix doc-string.
2310 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2312 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2313 amount when the scroll margins are too large. When scrolling
2314 backwards in the buffer, give up if cannot reach point or the
2315 scroll margin within a reasonable number of screen lines.
2316 Fixes point position in window under scroll-up/down-aggressively when
2317 point is positioned many lines beyond the window top/bottom.
2320 * ralloc.c (relinquish): If real_morecore fails to return memory
2321 to the system, don't crash; instead, leave the last heap
2322 unchanged and return. (Bug#12774)
2324 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2326 * lisp.h (AUTOLOADP): New macro.
2327 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2328 * data.c (Ffset): Remove special ad-advice-info handling.
2329 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2331 (Finteractive_form): Simplify.
2332 (Fquo): Don't insist on having at least 2 arguments.
2333 (Qdefalias_fset_function): New var.
2335 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2337 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2339 * nsfont.m (Qcondensed, Qexpanded): New variables.
2340 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2341 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2343 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2345 Fix recently introduced crash on MS-Windows (Bug#12839).
2346 * w32term.h (struct scroll_bar): Use convenient header.

2352 Tweak last vectorlike_header change.
2353 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2354 vectorlike object on the free list. This is introduced to avoid
2355 some (but not all) pointer casting and aliasing problems, see
2356 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2357 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

2361 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2363 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

2386 * lisp.h (sxhash_combine): New inline function, with the contents
2387 of the old SXHASH_COMBINE.
2388 * profiler.c (hashfn_profiler): Use it, instead of having a
2389 special hash function containing a comparison that always yields 1.
2391 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2393 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2394 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2395 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2398 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2400 * image.c (xpm_make_color_table_h): Fix compiler error because
2401 make_hash_table changed.
2403 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2405 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2407 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2409 Use ad-hoc comparison function for the profiler's hash-tables.
2410 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2411 (make_log): Use them.
2412 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2413 call Fequal any more.

2422 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2423 (hash_lookup, hash_remove_from_table): Move assertion checking of
2424 hashfn result here. Check hash-equality before calling cmpfn.

2436 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2437 value of w32-scroll-lock-modifier is neither nil nor one of the
2438 known key modifiers. (Bug#12806)
2440 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2442 Shrink struct vectorlike_header to the only size field.
2443 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2445 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2446 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2447 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2448 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2449 information from the vector header. Adjust comment.

2464 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2465 (large_vectors): Change type to struct large_vector.
2466 (allocate_vector_from_block): Simplify.
2467 (PSEUDOVECTOR_NBYTES): Replace with...
2468 (vector_nbytes): ...new function. Adjust users.

2470 (allocate_vectorlike): Likewise.
2471 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2472 Add easserts. Adjust XSETPVECTYPESIZE usage.
2473 (allocate_buffer): Use BUFFER_PVEC_INIT.
2474 (live_vector_p): Adjust to match large vector.
2475 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2476 * buffer.h (struct buffer): Add next member.
2477 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2479 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

2485 (xvecsize): New command.
2487 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2489 * keyboard.c (event_to_kboard): Do not dereference
2490 frame_or_window field of SELECTION_REQUEST_EVENT
2491 and SELECTION_CLEAR_EVENT events (Bug#12814).
2492 * xterm.h (struct selection_input_event): Adjust comment.
2494 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2496 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2497 such as Scroll Lock, if the respective keys are treated as
2498 function keys, not as modifiers. This avoids destroying non-ASCII
2499 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2501 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2503 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2505 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2507 Restore some duplicate definitions (Bug#12814).
2508 This undoes part of the 2012-11-03 changes. Some people build
2509 with plain -g rather than with -g3, and they need the duplicate
2510 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2511 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2512 Define as macros, as well as as enums or as constants.
2514 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2516 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2517 to keypad keys (Bug#12816).
2519 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2521 Minor adjustments of recently-changed frame functions.
2522 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2523 known to be a frame (we're in the FRAMEP branch).
2524 * lisp.h (Qframep): Remove decl. frame.h declares this.
2525 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2526 since they're meant for Lisp fixnum values.
2528 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2530 * window.c (Fwindow_combination_limit): Revert to the only
2531 required argument and adjust docstring as suggested in
2532 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2533 by Martin Rudalics <rudalics@gmx.at>.
2535 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2537 Widely used frame validity and checking functions.
2538 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2539 * frame.c (decode_live_frame, decode_any_frame): New functions.
2540 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2541 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2542 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

2549 (frame_buffer_list, frame_buffer_predicate): Remove.
2550 * lisp.h (frame_buffer_predicate): Remove prototype.
2551 * buffer.c (Fother_buffer): Use decode_any_frame.
2552 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2553 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2554 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2555 (Fclose_font, Ffont_info): Use decode_live_frame.
2556 * fontset.c (check_fontset_name): Likewise.
2557 * terminal.c (Fframe_terminal): Likewise.
2558 * w32fns.c (check_x_frame): Likewise.
2559 * window.c (Fminibuffer_window, Fwindow_at)
2560 (Fcurrent_window_configuration): Likewise.
2561 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2562 Likewise. Allow zero number of arguments. Adjust docstring.
2563 * dispnew.c (Fredraw_frame): Likewise.
2564 * xfaces.c (frame_or_selected_frame): Remove.
2565 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2566 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2567 (Fframe_face_alist): Use decode_live_frame.
2568 * xfns.c (check_x_frame): Likewise.
2570 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2572 * window.c (quad): New function.
2573 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2574 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2575 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2576 (Fwindow_line_height): Use it.
2577 (Fwindow_fringes): Use list3.
2578 (Fwindow_scroll_bars): Use list4.
2579 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2580 (Fwindow_combination_limit): Allow zero number of arguments.
2582 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2584 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2586 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2587 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2588 file descriptor 2 for standard error. (Bug#12805)
2590 2012-11-05 Chong Yidong <cyd@gnu.org>
2592 * process.c (wait_reading_process_output): Revert previous change.
2594 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2596 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2597 This removes code that has been obsolete since around 1990.
2598 * callproc.c (Fcall_process):
2600 * process.c (create_process):
2601 * term.c (dissociate_if_controlling_tty):
2602 Assume setsid exists.
2603 * callproc.c (child_setup): Assume setpgid exists and behaves as
2604 per POSIX.1-1988 or later.
2605 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2606 * emacs.c (shut_down_emacs):
2607 * sysdep.c (sys_suspend, init_foreground_group):
2608 Assume getpgrp behaves as per POSIX.1-1998 or later.
2609 * msdos.c (setpgrp): Remove.
2610 (tcgetpgrp, setpgid, setsid): New functions.
2611 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2612 * term.c (no_controlling_tty): Remove; unused.
2613 * w32proc.c (setpgrp): Remove.
2614 (setsid, tcgetpgrp): New functions.
2616 Simplify by assuming __fpending.
2617 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2618 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2619 Do not assume that __fpending's result fits in int.
2621 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2623 Remove EMACS_OUTQSIZE+sleep hack.
2624 * dispnew.c (update_frame_1): Remove hack for terminals slower
2625 than 2400 bps, which throttled Emacs by having it sleep.
2626 This code hasn't worked since at least 2007, when the multi-tty stuff
2627 was added, and anyway those old terminals are long dead.
2628 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2629 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2631 Fix data-loss with --version (Bug#9574).
2632 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2633 as we can't assume that emacs_strerror is initialized, and strerror
2634 is good enough here.
2635 (main): Invoke atexit earlier, to catch earlier instances of
2636 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2638 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2640 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2641 (keyDown): Remap keypad keys to X11 virtual key codes.
2643 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2645 Fix data-loss with --batch (Bug#9574).
2646 * emacs.c: Include <close-stream.h>.
2647 (close_output_streams): New function.
2648 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2649 and handles errors appropriately.
2650 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2653 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2654 The symptom is a diagnostic "GLib-WARNING **: In call to
2655 g_spawn_sync(), exit status of a child process was requested but
2656 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2657 waitpid(), so exit status can't be returned." The diagnostic
2658 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2659 The real bug is a race condition between Emacs and glib: Emacs
2660 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2661 so that glib can't find it. Work around the bug by invoking
2662 waitpid only on subprocesses that Emacs itself creates.
2663 * process.c (create_process, record_child_status_change):
2664 Don't use special value -1 in pid field, as the caller now must
2665 know the pid rather than having the callee infer it.
2666 The inference was sometimes incorrect anyway, due to another race.
2667 (create_process): Set new 'alive' member if child is created.
2668 (process_status_retrieved): New function.
2669 (record_child_status_change): Use it.
2670 Accept negative 1st argument, which means to wait for the
2671 processes that Emacs already knows about. Move special-case code
2672 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2673 processes that have already been waited for, by testing and
2674 clearing new 'alive' member.
2675 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2676 now does this internally.
2677 (handle_child_signal): Let record_child_status_change do all
2678 the work, since we do not want to reap all exited child processes,
2679 only the child processes that Emacs itself created.
2680 * process.h (Lisp_Process): New boolean member 'alive'.
2682 Omit duplicate definitions no longer needed with gcc -g3.
2683 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2684 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2685 Define only as macros. There's no longer any need to also define
2686 these symbols as enums or as constants, since we now assume
2687 gcc -g3 when debugging.
2689 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2691 * lisp.mk: Adjust comments to the fact that term/internal is now
2692 loaded from loadup.el.
2694 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2695 (msdos_fatal_signal): New function.
2696 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2699 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2700 for GCC versions before 4.
2701 (emacs_raise): Define to call msdos_fatal_signal.
2703 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2704 iterator when starting in the middle of a display or overlay
2707 2012-11-03 Chong Yidong <cyd@gnu.org>
2709 * process.c (wait_reading_process_output): Clean up the last
2712 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2714 * process.c (wait_reading_process_output): Avoid a race condition
2715 with SIGIO delivery (Bug#11536).
2717 2012-11-03 Chong Yidong <cyd@gnu.org>
2719 * buffer.c (cursor_type): Untabify docstring.
2721 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2723 * frame.h (struct frame): Drop can_have_scroll_bars member
2724 which is meaningless for a long time. Adjust comments.
2725 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2726 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2728 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2730 * window.c (decode_next_window_args): Update window arg after
2731 calling decode_live_window and so fix crash reported at
2732 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2733 by Juanma Barranquero <lekktu@gmail.com>.
2734 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2735 * font.c (Ffont_at): Likewise.
2737 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2739 * widget.c (resize_cb): New function.
2740 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2741 (EmacsFrameResize): Check if all is up to date before changing frame
2744 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2746 Implement backtrace output for fatal errors on MS-Windows.
2747 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2748 (BACKTRACE_LIMIT_MAX): New macro.
2749 (w32_backtrace): New function.
2750 (emacs_abort): Use w32_backtrace when the user chooses not to
2751 attach a debugger. Update the text of the abort dialog.
2753 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2755 Window-related stuff cleanup here and there.
2756 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2757 Use decode_any_window.
2758 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2759 * xdisp.c (Fformat_mode_line): Likewise.
2760 * font.c (Ffont_at): Use decode_live_window.
2761 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2762 * window.c (decode_next_window_args): Likewise.
2763 (decode_any_window): Remove static.
2764 * window.h (decode_any_window): Add prototype.
2765 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2766 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2769 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2771 Remove pad from struct input_event.
2772 * termhooks.h (struct input_event): Remove padding field.
2774 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2775 member is never cons for a long time. Adjust comment.
2776 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2777 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2778 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2779 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2781 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2783 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2785 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2787 Fix crash when using Emacs as commit editor for git (Bug#12697).
2788 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2789 and it is configured in conf_post.h.
2790 (Fcall_process): Don't invoke both setsid and setpgid; the former
2791 is enough, if it exists.
2792 * callproc.c (Fcall_process, child_setup):
2793 * process.c (create_process): Use setpgid.
2794 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2796 * dispnew.c (init_display): Initialize the foreground group
2797 if we are running a tty display.
2798 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2799 * lisp.h (init_foreground_group): New decl.
2800 * sysdep.c (inherited_pgroup): New static var.
2801 (init_foreground_group, tcsetpgrp_without_stopping)
2802 (narrow_foreground_group, widen_foreground_group): New functions.
2803 (init_sys_modes): Narrow foreground group.
2804 (reset_sys_modes): Widen foreground group.
2806 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2808 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2810 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2812 * minibuf.c (read_minibuf): Restore current buffer since
2813 choose_minibuf_frame calling Fset_frame_selected_window may
2814 change it (Bug#12766).
2816 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2818 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2820 2012-10-30 Kenichi Handa <handa@gnu.org>
2822 * font.c (Ffont_at): If WINDOW is specified and it is not
2823 displaying the current buffer, signal an error.
2825 2012-10-29 Daniel Colascione <dancol@dancol.org>
2827 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2828 In preparation for fixing bug#12739, move these functions from
2831 * coding.h, coding.c: ... to here, and compile them only when
2832 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2833 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2835 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2837 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2838 (timer_loop, getitimer, setitimer): Use it instead of
2839 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2841 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2844 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2846 * nsterm.m (NO_APPDEFINED_DATA): New define.
2847 (last_appdefined_event_data): New variable
2848 (last_appdefined_event): Remove.
2849 (ns_select): Initialize t from last_appdefined_event_data instead
2850 of [last_appdefined_event data1].
2851 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2852 remove last_appdefined_event (Bug#12698).
2854 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2856 * frame.c (x_set_font): Catch internal error.
2858 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2860 Avoid overflow in w32 implementation of interval timers.
2861 When possible, for ITIMER_PROF count only times the main thread
2863 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2864 'volatile ULONGLONG' types. All the other data which was
2865 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2866 (GetThreadTimes_Proc): New typedef.
2867 (w32_get_timer_time): New function, returns a suitable time value
2869 (timer_loop): Enter critical section when accessing ULONGLONG
2870 values of the itimer_data struct, as these accesses are no longer
2871 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2872 Remove unused variable.
2873 (init_timers): Initialize s_pfn_Get_Thread_Times.
2874 (start_timer_thread): Don't assign itimer->caller_thread here.
2875 (getitimer): Assign itimer->caller_thread here.
2876 (setitimer): Always call getitimer to get the value of ticks_now.
2877 (sys_spawnve): Avoid compiler warning about format mismatch.
2879 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2881 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2882 mouse movement events if the menu bar is active. This avoids
2883 producing a busy "hour-glass" cursor by Windows if the mouse
2884 pointer is positioned over a tooltip shown for some menu item.
2886 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2888 Don't assume process IDs fit in int.
2889 * emacs.c (shut_down_emacs) [!DOS_NT]:
2890 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2891 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2892 Use pid_t, not int, to store process IDs, as 'int'
2893 is not wide enough on a few platforms (e.g., AIX and IRIX).
2895 2012-10-23 Kenichi Handa <handa@gnu.org>
2897 The following change is to make face-font-rescale-alist work
2898 correctly for non-ASCII fonts.
2900 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2901 (font_open_for_lface): Handle Vface_font_rescale_alist.
2903 2012-10-23 Chong Yidong <cyd@gnu.org>
2905 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2907 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2911 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2913 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2916 2012-10-21 Glenn Morris <rgm@gnu.org>
2918 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2920 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2922 Port to OpenBSD 5.1.
2923 * frame.c (Fmouse_position, Fmouse_pixel_position):
2924 * xdisp.c (produce_stretch_glyph):
2925 Declare local vars only when they're needed.
2926 This is clearer and avoids a warning on OpenBSD about unused vars.
2927 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2928 This is safer, and avoids OpenBSD warnings about unused vars.
2929 * keyboard.c (record_menu_key): Remove unnecessary decl.
2930 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2931 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2932 as our definition clashes with OpenBSD's.
2933 * xfaces.c (load_face_colors, check_lface_attrs)
2934 (get_lface_attributes_no_remap, get_lface_attributes)
2935 (lface_fully_specified_p, x_supports_face_attributes_p)
2936 (tty_supports_face_attributes_p, face_fontset, realize_face)
2937 (realize_x_face, realize_tty_face):
2938 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2939 merely Lisp_Object *. This is more informative and avoids
2940 a warning on OpenBSD about accessing beyond an object's size.
2942 2012-10-20 Chong Yidong <cyd@gnu.org>
2944 * lread.c (Fload): Doc fix (Bug#12592).
2946 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2948 * font.c (Ffont_at): Fix previous change.
2950 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2952 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2953 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

2970 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2971 (staticpro): If we run out of staticpro slots, die with an
2972 informative error instead of just calling emacs_abort.
2974 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2976 Fix two flaws reported by Dmitry Antipov.
2977 * window.c (Ftemp_output_buffer_show): Remove.

3233 (get_input_pending): Remove first argument, since it was always
3234 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3235 and behave as if it had that value. Return new value of
3236 input_pending. All callers changed.
3237 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3238 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3260 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
3261 Don't include termopts.h.
3263 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3265 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3267 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3269 * commands.h (immediate_quit): Remove duplicate decl.
3271 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3273 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
3275 (nsfont_open): Remove setting of Vfonts_in_cache.
3276 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3278 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3280 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3281 match what GetLastError returns. Explain why the function is
3284 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3285 'is_tooltip_frame', to avoid confusion with its global namesake.
3287 2012-10-08 Daniel Colascione <dancol@dancol.org>
3289 * xdisp.c (start_hourglass): Call w32_note_current_window when
3290 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3291 build that caused Emacs to display the hourglass cursor forever.
3293 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3294 which is broken under remote desktop, calculate the number of
3295 colors available for a display based on the display's number of
3296 planes and number of bits per pixel per plane. (bug#10397).
3298 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3300 * nsfont.m (Vfonts_in_cache): New variable.
3301 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3302 are used. Add cached fonts to Vfonts_in_cache.
3303 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3305 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3307 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3309 (FONT_H): Define after FRAME_H.
3310 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3311 Update dependencies.
3313 * w32term.c: Remove leftover declaration of keyboard_codepage.
3315 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3317 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3318 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3319 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3320 (GLOBAL_SOURCES): Add cygw32.c.
3321 ($(BLD)/unexw32.$(O)):
3323 ($(BLD)/w32console.$(O)):
3324 ($(BLD)/w32fns.$(O)):
3325 ($(BLD)/w32heap.$(O)):
3326 ($(BLD)/w32menu.$(O)):
3327 ($(BLD)/w32proc.$(O)): Add w32common.h.
3329 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3331 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3333 2012-10-08 Daniel Colascione <dancol@dancol.org>
3335 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3336 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3337 accidental message numbering hole. Change other messages to
3340 * w32select.h (HAVE_W32SELECT): Remove.
3342 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3343 w32common.h instead of w32heap.h.
3345 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3346 (get_allocation_unit, get_processor_type, get_w32_major_version)
3347 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3348 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3349 (OS_NT, os_subtype, cache_system_info): Move declarations to
3352 * w32heap.c: Include w32common.h.
3353 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3354 (w32_minor_version, w32_build_number, w32_subtype):
3355 Remove duplicate definitions.
3357 * w32fns.c: Include w32common.h; include w32heap.h only in
3360 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3361 Use `report_file_error' instead of `error' in order to better
3362 inform users of what went wrong. Increase NTGUI_UNICODE file
3363 dialog box file name length to 32k, the maximum allowed by the NT
3366 * w32common.h: New file.
3367 (ROUND_UP, ROUND_DOWN, get_page_size)
3368 (get_allocation_unit, get_processor_type, get_w32_major_version)
3369 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3370 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3371 (OS_NT, os_subtype, cache_system_info): Move here.
3373 * unexw32.c, unexcw.c: Include w32common.h.
3375 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3376 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3377 to call syms_of_w32select.
3379 * cygw32.h: Remove obsolete EXFUN declarations.
3381 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3383 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3384 of w32inevt.o from SOME_MACHINE_OBJECTS.
3386 2012-10-08 Daniel Colascione <dancol@dancol.org>
3388 * image.c: Permanent fix for JPEG compilation issue --- limit
3389 jpeglib `boolean' redefinition to Cygwin builds.
3391 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3393 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3395 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3398 2012-10-08 Daniel Colascione <dancol@dancol.org>
3400 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3401 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3402 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3403 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3404 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3405 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3406 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3407 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3408 now a supported configuration.
3410 * Makefile.in: consolidate image variables into LIBIMAGE; add
3411 W32_OBJ and W32_LIBS. Compile new files.
3414 (_DebPrint) declare tracing facility for W32 debugging. We need
3415 to unify tracing later.
3417 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3418 unconditional use of W32 Unicode functions. Cygwin runs only on
3419 100% Unicode operating systems.
3421 * cygw32.c: New file. Define Cygwin-specific facilities.
3422 (Fcygwin_convert_path_to_windows)
3423 (Fcygwin_convert_path_from_windows): New user functions for
3424 accessing Cygwin path-munging routines.
3426 * cygw32.h: New file.
3427 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3428 UTF-16LE strings temporarily inside non-Lisp-visible string
3431 (w32_strerror): Just what it says on the tin.
3433 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3434 also run for Cygwin; both systems have the same problem with using
3435 GUI facilities in a forked child. Also call syms_of_cygw32,
3436 syms_of_w32select in correct places.
3438 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3439 needs fork-then-exec for daemon launching.
3441 * font.h: Include frame.h.
3443 * image.c: Use the image library cache machinery only when we're
3444 compiling for native WINDOWSNT; Cygwin can use shared libraries
3445 like any other Unixlike system.
3447 * keyboard.c: Clarify a comment regarding the input loop.
3449 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3450 functions directly instead of trying to detect at runtime that our
3451 host operating system supports them. We make this change for two
3452 reasons: Cygwin lacks support for the multibyte character
3453 conversion functions used by the legacy menu code, and Cygwin
3454 never needs to rely on non-Unicode APIs.
3456 * unexw32.c (hinst): Declare extern.
3458 * w32.c: Change header order;
3459 (w32_strerror): Move to w32fns.c because we need it for
3460 non-WINDOWSNT builds.
3462 * w32.h: Add #error macro to make sure we don't include w32.h for
3463 Cygwin builds. Remove w32select declarations.
3465 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3466 w32fns.c. w32console.c is WINDOWSNT-only.
3468 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3469 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3471 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3472 (w32_major_version, w32_minor_version, w32_build_number)
3473 (os_subtype, sound_type): Define here
3474 (w32_defined_color): Make color parameter const for consistency
3475 with other _defined_color functions.
3476 (w32_createwindow): Unconditionally call w32_init_class instead of
3477 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3478 through the code is complex and unnecessary because class
3479 registration is practically free.
3480 (w32_name_of_message): New EMACSDEBUG-only function.
3481 (Fset_message_beep): Move here
3482 (Fx_open_connection): Require that the display name for Windows be
3483 "w32" for consistency, emacsclient disambiguation, and maybe, one
3484 day, multi-window-system support.
3485 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3486 Cygwin files for W32 GUI facilities, since these clearly don't
3487 expect Cygwin names.
3488 (_DebPrint): Define.
3489 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3490 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3491 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3492 (w32_last_error): Remove.
3494 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3496 * w32heap.c (syspage_mask): Declare here.
3497 (cache_system_info): Remove.
3499 * w32inevt.c (faked_key): Define globally, not statically.
3500 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3501 (w32_console_toggle_lock_key): Move to w32fns.c.
3503 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3505 * w32proc.c (_DebPrint): Move to w32fns.c.
3506 * w32select.c: Include string.h, stdio.h for Cygwin.
3507 * w32select.h: New File.
3509 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3511 (w32_message_fd): New variable. Under Cygwin, holds the file
3512 descriptor the system used to tell us about pending thread
3515 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3516 that prevented compilation under non-WINDOWSNT systems.
3518 (w32_initialize): Open /dev/windows and assign it to
3519 w32_message_fd. Provide w32 feature.
3521 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3522 (WM_EMACS_INPUT_READY): add.
3523 (prepend_msg, w32_message_fd): Declare globally.
3526 (keyboard_handle): Use only when WINDOWSNT.
3527 (notify_msg_ready): New function. Posts a message to the main
3528 thread's message queue under CYGWIN, which wakes up the main
3529 thread from select(2) by making the /dev/windows file descriptor
3530 ready. Under WINDOWSNT, it sets an event the same way the old
3533 (post, prepend_msg): Actually call notify_msg_ready instead of
3534 setting the input event directly.
3536 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3538 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3539 but it still has blocs in it, don't return it to the system,
3540 instead of aborting. (Bug#12402)
3542 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3544 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3546 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3547 MAC_OS_X_VERSION_10_6.
3548 (syms_of_nsterm): Remove comment about Panther and above for
3550 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3551 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3552 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3554 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3555 MAC_OS_X_VERSION_10_4.
3557 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3558 MAC_OS_X_VERSION_10_2.
3560 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3562 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3563 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3565 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3566 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3567 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3568 Remove ns_in_resize check.
3569 (ns_clear_frame_area): Remove resize handle code.
3571 * nsfns.m (ns_in_resize): Remove.
3572 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3573 Remove ns_in_resize check.
3575 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3577 Improve sys_siglist detection.
3578 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3579 defined as a macro, as is done in Solaris.
3580 (sys_siglist_entries): New macro.
3581 (save_strsignal): Use it.
3582 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3583 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3585 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3587 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3588 fullscreen/Fullscreen.
3590 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3591 tobar_height is new.
3593 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3594 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3595 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3596 (windowDidResize:): Check for correct window if old style fullscreen.
3597 Capitalize word in comment. Remove incorrect comment.
3598 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3599 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3600 error in drawing background.
3601 (toggleFullScreen:): Remove comment. Rearrange calls.
3602 Set toolbar values to zero, save old height in tobar_height.
3603 Restore tool bar height when leaving fullscreen.
3604 (canBecomeMainWindow): New function.
3606 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3608 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3610 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3612 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3614 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3615 that time stamps of directories could also be changed.
3616 Don't request the too broad GENERIC_WRITE, only the more restrictive
3617 FILE_WRITE_ATTRIBUTES access rights.
3619 * fileio.c (Fset_file_times): Special-case ignoring errors for
3620 directories only on MSDOS, not on MS-Windows.
3622 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3624 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3626 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3628 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3629 see whether CreateFile failed.
3631 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3633 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3634 to avoid similar races.
3635 * keyboard.c (pending_signals): Now bool, not int.
3637 Port timers to OpenBSD, plus check for timer failures.
3638 OpenBSD problem reported by Han Boetes.
3639 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3641 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3642 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3643 like OpenBSD, which has timer_settime but does not declare it.
3644 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3645 whether to use itimerspec-related primitives. All uses of
3646 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3648 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3650 * profiler.c (handle_profiler_signal): Fix a malloc race
3651 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3653 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3655 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3657 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3659 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3660 consistent with the change in return value of 'safe_strsignal'.
3662 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3664 Prefer plain 'static' to 'static inline' (Bug#12541).
3665 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3666 (bidi_set_sor_type, bidi_push_embedding_level)
3667 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3668 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3669 (bidi_cache_search, bidi_cache_ensure_space)
3670 (bidi_cache_iterator_state, bidi_cache_find)
3671 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3672 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3673 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3674 Now 'static', not 'static inline'.
3676 Count overruns when profiling; change units to ns.
3677 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3678 Give extra weight to samples after overruns, to attempt to count
3679 the time more accurately.
3680 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3681 the underlying primitives nominally do ns.
3682 (Fprofiler_cpu_start): Document the change. Mention that
3683 the sampling intervals are only approximate.
3685 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3687 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3689 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3690 case for the special 0 coding-system.
3692 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3693 (Fmake_overlay): Remove redundant tests.
3694 (fix_start_end_in_overlays): Remove redundant recentering.
3696 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3698 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3699 Update dependencies.
3701 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3703 Fix a malloc race condition involving strsignal.
3704 A signal can arrive in the middle of a malloc, and Emacs's signal
3705 handler can invoke strsignal, which can invoke malloc, which is
3706 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3707 Fix it by altering the signal handler so that it does not invoke
3709 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3710 * process.c (status_message): Use const pointer, in case strsignal
3711 is #defined to safe_strsignal.
3712 * sysdep.c (sys_siglist, init_signals): Always define and
3713 initialize a substitute sys_siglist if the system does not define
3714 one, even if HAVE_STRSIGNAL.
3715 (safe_strsignal): Rename from strsignal. Always define,
3716 using sys_siglist. Return a const pointer.
3717 * syssignal.h (safe_strsignal): New decl.
3718 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3720 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3722 * w32proc.c (timer_loop): Fix code that waits for timer
3723 expiration, to avoid high CPU usage.
3725 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3727 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3728 (sweep_weak_table): Remove redundant prototypes.
3730 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3732 * emacs.c: Move the inclusion of TERM_HEADER after including
3733 windows.h on WINDOWSNT. This avoids compilation problems with
3736 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3738 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3739 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3740 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3741 as the previous version used 'void *'.
3743 * ralloc.c (ROUNDUP): Fix last change.
3744 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3747 * w32proc.c <disable_itimers>: New static flag.
3748 (init_timers): Initialize it to zero, after creating the critical
3749 sections used by the timer threads.
3750 (term_timers): Set to 1 before deleting the critical sections.
3751 (getitimer, setitimer): If disable_itimers is non-zero, return an
3752 error indication without doing anything. Reported by Fabrice
3753 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3754 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3756 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3759 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3760 term_ntproc after all the other bookkeeping, to get timers working
3761 as long as possible.
3763 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3765 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3766 Suggested by Juri Linkov in
3767 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3769 Prefer plain 'static' to 'static inline' (Bug#12541).
3770 With static functions, modern compilers inline pretty well by
3771 themselves; advice from programmers often hurts as much as it helps.
3772 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3773 this change shrinks the text size of the Emacs executable by 1.1%
3774 without affecting CPU significantly in my benchmark.
3775 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3855 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3857 Revert the FOLLOW-SYMLINKS change for file-attributes.
3858 Doing it right would require several changes to Tramp, and there's
3859 not enough time to get that tested before the freeze today.
3860 * dired.c (directory_files_internal, Ffile_attributes):
3863 * frame.c (x_report_frame_params): Port better to wider ints.
3864 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3865 or that pointers can be printed in 15 decimal digits.
3866 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3902 * vm-limit.c (lim_data): Now size_t.
3903 (check_memory_limits): Adjust prototypes of real_morecore and
3904 __morecore to receive argument of type ptrdiff_t. Use size_t for

3930 * frame.c (x_report_frame_params): Use EMACS_UINT for the return
3931 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

3960 (struct itimer_data): New definition.
3961 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)

3973 Windows-specific code to display the hourglass mouse pointer is no
3975 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
3976 to hourglass timer expiration.

4057 Profiler improvements: more-accurate timers, overflow checks.
4058 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4059 signal.h, setjmp.h. Include systime.h instead.
4060 (saturated_add): New function.

4067 All uses changed to store the new value.
4068 (handle_profiler_signal): Rename from sigprof_handler_1,
4069 for consistency with other handlers. Do not check whether
4070 cpu_log is a hash-table if garbage collecting, since it
4071 doesn't matter in that case.

4073 for consistency with other handlers.
4074 (setup_cpu_timer): New function, with much of what used to be in
4075 Fprofiler_cpu_start. Check for out-of-range argument.
4076 Prefer timer_settime if available, and prefer
4077 thread cputime clocks, then process cputime clocks, then
4078 monotonic clocks, to the old realtime clock. Use make_timeval
4079 to round more-correctly when falling back to setitimer.
4080 (Fprofiler_cpu_start): Use it.
4081 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4082 Don't assume that passing NULL as the 2nd argument of setitimer
4083 is the same as passing a pointer to all-zero storage.
4084 Ignore SIGPROF afterwards.
4085 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4086 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4087 non-fatal signal handlers. Ignore SIGPROF on startup.
4088 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4089 in profiler.c, since sysdep.c now uses it.
4091 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4147 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4148 Since this stuff is now private to charset.c, there's no need for
4149 a public macro and no need to inline by hand.

4177 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4178 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4180 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4182 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4184 Prefer POSIX timers if available.
4185 They avoid a race if the timer is too close to the current time.
4186 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4187 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4188 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4190 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4192 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
4193 CHAR_STRING_ADVANCE.
4194 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
4195 STRING_CHAR_ADVANCE.
4197 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4199 Move Vlibrary_cache to emacs.c and reset before dumping.
4201 * lisp.h (reset_image_types): Declare.
4202 [WINDOWSNT] (Vlibrary_cache): Declare.
4204 * image.c (reset_image_types): New function.
4206 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
4207 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
4208 (Fdump_emacs): Reset Vlibrary_cache and image_types.

4211 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
4213 * w32.h (Vlibrary_cache): Do not declare.
4215 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4217 * w32proc.c (sys_signal): Handle all signals defined by the
4218 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4219 handlers for signals supported by Windows. Don't override
4220 term_ntproc as the handler for SIGABRT.
4221 (sigaction): Rewrite to call sys_signal instead of duplicating its
4223 (sys_kill): Improve commentary.
4225 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4226 consistency with a signature of a signal handler. All callers
4228 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4229 install term_ntproc as a signal handler for SIGABRT, as that
4230 should be done by the dumped Emacs.
4232 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4234 * w32select.c (term_w32select): Protect against repeated
4235 invocation by setting clipboard_owner to NULL after calling
4238 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
4239 and term_ntproc to their modified signatures.
4241 * character.c (char_string, string_char): Remove calls to
4242 MAYBE_UNIFY_CHAR. See the discussion starting at
4243 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4246 2012-09-25 Chong Yidong <cyd@gnu.org>
4248 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4250 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4252 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4253 when encountering an unknown bytecode.
4255 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4257 image.c, indent.c: Use bool for booleans.
4258 * dispextern.h (struct image_type): Members valid_p, load, init
4259 now return bool, not int. All uses changed.
4260 * image.c: Omit unnecessary static decls.
4261 (x_create_bitmap_mask, x_build_heuristic_mask):
4262 Return void, not int, since callers don't care about the return value.

4291 Use bool for booleans.
4293 2012-09-24 Chong Yidong <cyd@gnu.org>
4295 * chartab.c (Fset_char_table_default): Obsolete function removed.
4297 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4299 Move pid_t related decls out of lisp.h.
4300 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4301 (interruptible_wait_for_termination):
4302 Move these decls from lisp.h to syswait.h, since they use pid_t.
4303 Needed on FreeBSD; see Herbert J. Skuhra in
4304 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4305 * callproc.c: Include syswait.h.

4323 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4324 * xfns.c (Fx_show_tip) [USE_GTK]:
4325 Use bool for boolean.
4326 * gtkutil.c (xg_update_frame_menubar):
4327 * xmenu.c (update_frame_menubar):
4328 Return void, not int, since caller ignores return value.
4329 * gtkutil.c (xg_change_toolbar_position):
4332 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4334 * makefile.w32-in (BLOCKINPUT_H): Remove.

4351 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4353 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4354 fatal_error_backtrace.
4356 * w32proc.c (sys_kill): Undo last change: don't do anything when
4357 invoked to deliver SIGABRT to our own process. This is now
4358 handled by emacs_raise.
4360 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4362 * w32term.c (w32_read_socket): Remove leftover reference to
4363 interrupt_input_pending.
4365 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4367 Do not use SA_NODEFER.
4368 Problem reported by Dani Moncayo in
4369 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4371 * sysdep.c (emacs_abort): Do not reset signal handler.
4372 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4373 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4374 wanted even on POSIXish hosts, and it doesn't work on Windows.
4376 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4378 * xterm.c (x_term_init): Call fixup_locale before and after calling
4379 gtk_init (Bug#12392).
4381 2012-09-23 Chong Yidong <cyd@gnu.org>
4383 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4384 Vdynamic_library_alist.
4386 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4387 (Fgnutls_available_p): Caller changed.
4389 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4390 (Flibxml_parse_xml_region): Likewise.
4392 * dispextern.h (struct image_type): Remove arg from init function.
4394 * image.c (Finit_image_library, lookup_image_type)
4395 (define_image_type): Remove now-unneeded second arg.
4396 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4397 (init_tiff_functions, init_gif_functions, init_svg_functions):
4398 Arglist and w32_delayed_load calling convention changed.
4399 (gs_type): Remove init_gs_functions; there is no such function.
4400 (valid_image_p, make_image): Fix caller to lookup_image_type.
4402 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4404 Simplify and avoid signal-handling races (Bug#12471).
4406 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4407 Avoid recursive loop if there's a fatal error in the function itself.
4408 * atimer.c (pending_atimers):
4409 * blockinput.h: Don't include "atimer.h"; no longer needed.
4410 (interrupt_input_pending): Remove. All uses removed.
4411 pending_signals now counts both atimers and ordinary interrupts.
4412 This is less racy than having three separate pending-signal flags.
4413 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4415 Rename from their upper-case counterparts BLOCK_INPUT,
4416 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4417 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4418 This makes it easier to access volatile variables more accurately.
4419 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4420 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4421 that's more reliable if the code is buggy and sets
4422 interrupt_input_blocked to a negative value. All uses changed.
4423 * atimer.c (deliver_alarm_signal):
4424 Remove. No need to deliver this to the parent; any thread can
4425 handle this signal now. All uses replaced by underlying handler.
4426 * atimer.c (turn_on_atimers):
4427 * dispnew.c (handle_window_change_signal):
4428 * emacs.c (handle_danger_signal):
4429 * keyboard.c (kbd_buffer_get_event):
4430 Don't reestablish signal handler; not needed with sigaction.
4431 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4433 Rework to avoid unnecessary accesses to volatile variables.
4434 (UNBLOCK_INPUT_TO): Now a function.
4435 (totally_unblock_input, unblock_input): New decls.
4436 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4437 (init_data): Remove. Necessary stuff now done in init_signal.
4438 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4439 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4440 (fatal_error_code): Remove; no longer needed.
4441 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4442 it doesn't always backtrace. All uses changed. No need to reset
4443 signal to default, since sigaction and/or die does that for us now.
4444 Use emacs_raise (FOO), not kill (getpid (), FOO).
4445 (main): Check more-accurately whether we're dumping.
4446 Move fatal-error setup to sysdep.c
4447 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4448 * gtkutil.c (xg_get_file_name, xg_get_font):
4449 Remove no-longer-needed signal-mask manipulation.
4450 * keyboard.c, process.c (POLL_FOR_INPUT):
4451 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4452 * keyboard.c (read_avail_input): Remove.
4453 All uses replaced by gobble_input.
4454 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4455 (kbd_buffer_store_event_hold, gobble_input):
4456 (record_asynch_buffer_change) [USABLE_SIGIO]:
4457 (store_user_signal_events):
4458 No need to mess with signal mask.
4459 (gobble_input): If blocking input and there are terminals, simply
4460 set pending_signals to 1 and return. All hooks changed to not
4461 worry about whether input is blocked.
4462 (process_pending_signals): Clear pending_signals before processing
4463 them, in case a signal comes in while we're processing.
4464 By convention callers now test pending_signals before calling us.
4465 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4466 New functions, to support changes to blockinput.h.
4467 (handle_input_available_signal): Now extern.
4468 (reinvoke_input_signal): Remove. All uses replaced by
4470 (quit_count): Now volatile, since a signal handler uses it.
4471 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4472 All callers changed. Block SIGINT only if not already blocked.
4473 Clear sigmask reliably, even if Fsignal returns, which it can.
4474 Omit unnecessary accesses to volatile var.
4475 (quit_throw_to_read_char): No need to restore sigmask.
4476 * keyboard.c (gobble_input, handle_user_signal):
4477 * process.c (wait_reading_process_output):
4478 Call signal-handling code rather than killing ourselves.
4479 * lisp.h: Include <float.h>, for...
4480 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4481 (pending_signals): Now volatile.
4482 (syms_of_data): Now const if IEEE floating point.
4483 (handle_input_available_signal) [USABLE_SIGIO]:
4484 (terminate_due_to_signal, record_child_status_change): New decls.
4485 * process.c (create_process): Avoid disaster if memory is exhausted
4486 while we're processing a vfork, by tightening the critical section
4488 (send_process_frame, process_sent_to, handle_pipe_signal)
4489 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4491 (send_process): No need for setjmp/longjmp any more, since the
4492 SIGPIPE stuff is now gone. Instead, report an error if errno
4494 (record_child_status_change): Now extern. PID and W are now args.
4495 Return void, not bool. All callers changed.
4496 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4497 Remove. All uses removed. This bug should be fixed now in a
4499 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4500 and record the child status change directly. This avoids the
4501 need to futz with the signal mask.
4502 (process_fatal_action): Move here from emacs.c.
4503 (emacs_sigaction_flags): New function, containing
4504 much of what used to be in emacs_sigaction_init.
4505 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4506 caught by emacs, to make races less likely.
4507 (deliver_process_signal): Rename from handle_on_main_thread.
4509 (BACKTRACE_LIMIT_MAX): Now at top level.
4510 (thread_backtrace_buffer, threadback_backtrace_pointers):
4512 (deliver_thread_signal, deliver_fatal_thread_signal):
4513 New functions, for more-accurate delivery of thread-specific signals.
4514 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4515 (deliver_arith_signal): Handle in this thread, not
4516 in the main thread, since it's triggered by this thread.
4517 (maybe_fatal_sig): New function.
4518 (init_signals): New arg DUMPING so that we can be more accurate
4519 about whether we're dumping. Caller changed.
4520 Treat thread-specific signals differently from process-general signals.
4521 Block all signals while handling fatal error; that's safer.
4522 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4524 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4525 Ignore SIGPIPE unless batch.
4526 (emacs_backtrace): Output backtrace for the appropriate thread,
4527 which is not necessarily the main thread.
4528 * syssignal.h: Include <stdbool.h>.
4529 (emacs_raise): New macro.
4530 * xterm.c (x_connection_signal): Remove; no longer needed
4531 now that we use sigaction.
4532 (x_connection_closed): No need to mess with sigmask now.
4533 (x_initialize): No need to reset SIGPIPE handler here, since
4534 init_signals does this for us now.
4536 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4538 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4539 background rect may be larger (Bug#12245).
4541 2012-09-23 Chong Yidong <cyd@gnu.org>
4543 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4545 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4547 * .gdbinit: Just stop at fatal_error_backtrace.
4548 See Stefan Monnier's request in
4549 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4550 Remove no-longer-used query of system type.
4552 2012-09-22 Chong Yidong <cyd@gnu.org>
4554 * search.c (Freplace_match): Doc fix (Bug#12325).
4556 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4558 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4559 (Fline_end_position): Doc fix.
4561 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4563 2012-09-22 Chong Yidong <cyd@gnu.org>
4565 * dispextern.h (struct image_type): Add new slot, storing a type
4566 initialization function.
4568 * image.c (define_image_type): Call the image initializer function
4569 if it is defined. Arguments and return value changed.
4570 (valid_image_p, make_image): Callers changed.
4571 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4572 (gif_type, imagemagick_type, svg_type, gs_type):
4573 Add initialization functions.
4574 (Finit_image_library): Call lookup_image_type.
4575 (CHECK_LIB_AVAILABLE): Macro deleted.
4576 (lookup_image_type): Call define_image_type here, rather than via
4577 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4578 (syms_of_image): Move define_image_type calls for xbm_type and
4579 pbm_type to lookup_image_type.
4581 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4583 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4584 'idle_timers' from here ...
4585 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4586 lists, to avoid infloops when the timer does something stupid,
4587 like reinvoke itself with the same or smaller time-out.
4590 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4592 * window.c (Fsplit_window_internal): Handle only Qt value of
4593 Vwindow_combination_limit separately.
4594 (Qtemp_buffer_resize): New symbol.
4595 (Vwindow_combination_limit): New default value.
4598 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4600 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4601 the new overlay string. (Bug#10159)
4603 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4605 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4606 or that fprintf is async-signal-safe. POSIX doesn't require
4609 2012-09-22 Chong Yidong <cyd@gnu.org>
4611 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4614 2012-09-22 Kenichi Handa <handa@gnu.org>
4616 * composite.c (composition_reseat_it): Handle the case that a
4617 grapheme cluster is not covered by a single font (Bug#12352).
4619 2012-09-21 Chong Yidong <cyd@gnu.org>
4621 * image.c (define_image_type): Avoid adding duplicate types to
4622 image_types (Bug#12463). Suggested by Jörg Walter.
4624 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4626 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4627 (print_load_command_name): Add case LC_DATA_IN_CODE.
4628 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4630 2012-09-21 Glenn Morris <rgm@gnu.org>
4632 * eval.c (Frun_hook_with_args_until_success)
4633 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4635 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4637 * fileio.c (Ffile_selinux_context): Only call freecon when
4638 lgetfilecon succeeded.
4639 (Fset_file_selinux_context): Likewise. (Bug#12444)
4641 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4643 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4644 reordering, locate the cursor by calling set_cursor_from_row; if
4645 that fails, clear the desired glyph matrix before returning a
4646 failure indication to the caller. Fixes leaving garbled display
4647 when fast scrolling with a down-key. (Bug#12403)
4648 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4649 scrolling through multibyte text.
4651 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4653 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4654 calling mark_vectorlike since that's the one that marks the window.
4655 (mark_discard_killed_buffers): Mark the final cdr.
4656 * window.h (struct window): Move prev/next_buffers to the
4657 non-standard fields.
4658 * window.c (make_window): Initialize prev/next_buffers manually.
4660 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4662 Omit unused arg EXPECTED from socket hooks.
4663 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4664 * nsterm.m (ns_term_init):
4665 * termhooks.h (struct terminal.read_socket_hook):
4666 * w32inevt.c (w32_console_read_socket):
4667 * w32term.c (w32_read_socket):
4668 * xterm.c (XTread_socket):
4669 Omit unused arg EXPECTED. All callers changed.
4670 (store_user_signal_events): Return void, not int, since callers no
4671 longer care about the return value. All uses changed.
4673 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4675 * w32gui.h (XParseGeometry): Do not declare.
4677 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4679 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4680 Ignore 'expected'. See Eli Zaretskii in
4681 <http://bugs.gnu.org/12471#8> (last line).
4683 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4684 (XParseGeometry): Now static. Substitute extremal values for
4685 values that are out of range.
4687 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4689 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4691 * nsfns.m (XParseGeometry): Remove.
4692 (Fx_create_frame): Call x_set_offset to correctly interpret
4693 top_pos in geometry.
4695 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4696 (Fx_parse_geometry): If there is a space in string, call
4697 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4699 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4701 * search.c (scan_buffer): Use character positions in calls to
4702 region_cache_forward and region_cache_backward, not byte
4703 positions. (Bug#12196)
4705 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4706 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4708 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4709 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4710 emacs_blocked_malloc, now deleted.
4712 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4714 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4715 The workaround was for improving performance on Solaris 2.4, but
4716 is getting in the way now. Emacs will still work if someone is
4717 still running Solaris 2.4 in a museum somewhere; Sun dropped
4718 support for Solaris 2.4 in 2003.
4719 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4720 * process.c (create_process) [HAVE_WORKING_VFORK]:
4721 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4722 since Emacs no longer uses vfork on that platform.
4724 2012-09-17 Glenn Morris <rgm@gnu.org>
4726 * emacs.c: Use COPYRIGHT.
4728 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4730 Remove configure's --without-sync-input option (Bug#12450).
4731 When auditing signal-handling in preparation for cleaning it up,
4732 I found that SYNC_INPUT has race conditions and would be a real
4733 pain to fix. Since it's an undocumented and deprecated
4734 configure-time option, now seems like a good time to remove it.
4735 Also see <http://bugs.gnu.org/11080#16>.
4736 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4737 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4738 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4739 (malloc_hysteresis):
4740 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4741 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4742 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4743 (dont_register_blocks, bytes_used_when_reconsidered)
4744 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4745 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4746 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4747 Remove. All uses removed.
4748 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4749 implementation, one that depends on whether the new macro
4750 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4752 * atimer.c (run_timers, handle_alarm_signal):
4753 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4754 (handle_async_input, process_pending_signals)
4755 (handle_input_available_signal, init_keyboard):
4756 * nsterm.m (ns_read_socket):
4757 * process.c (wait_reading_process_output):
4758 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4759 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4761 * xterm.c (XTread_socket):
4763 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4764 * eval.c (handling_signal): Remove. All uses removed.
4765 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4766 All uses replaced with the SYNC_INPUT version.
4767 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4769 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4772 * font.c (Ffont_shape_gstring): Remove unused local.
4774 2012-09-16 Glenn Morris <rgm@gnu.org>
4776 * Makefile.in (clean): No longer run nextstep's clean.
4778 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4780 (ns-app): Move here from ns.mk, and simplify.
4781 (clean): Simplify nextstep entry.
4782 * ns.mk: Remove file.
4784 2012-09-17 Kenichi Handa <handa@gnu.org>
4786 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4787 not covert the last few charactes.
4789 2012-09-16 Kenichi Handa <handa@gnu.org>
4791 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4792 here, but just check the validity of glyphs in the glyph-string.
4794 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4796 * window.c (Fwindow_parameter, Fset_window_parameter):
4797 Accept any window as argument (Bug#12452).
4799 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4801 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4802 to ns_term_init to avoid memory leak.
4804 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4805 explicit retain/release.
4806 (ns_term_init): Only allow one display. Initialize outerpool and
4809 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4811 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4812 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4813 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4814 the Microsoft problem in a different way, by altering ../nt/config.nt.
4816 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4831 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4832 by lisp.h. This completes removal of setjmp.h inclusion
4833 erroneously announced in the previous commit. (Bug#12446)
4835 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4838 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4839 not defined as a macro. The latter happens on MS-Windows.
4842 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4844 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4845 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4846 Some instances of '#include <setjmp.h>' removed, if the
4847 only reason for the instance was because "lisp.h" was included.
4848 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4849 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4850 and _longjmp with the new symbols. Emacs already uses _setjmp if
4851 available, so this change affects only POSIXish hosts that have
4852 sigsetjmp but not _setjmp, such as some versions of Solaris and
4853 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4854 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4855 (png_load_body) [HAVE_PNG]:
4856 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4857 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4858 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4859 since PNG requires jmp_buf. This is the only exception to the
4860 general rule that we now use sys_setjmp and sys_longjmp.
4861 This exception is OK since this code does not change the signal
4862 mask or longjmp out of a signal handler.
4864 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4866 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4867 Include "syssignal.h", for 'main_thread'.
4869 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4871 Avoid out-of-range marker position (Bug#12426).
4872 * insdel.c (replace_range, replace_range_2):
4873 Adjust markers before overlays, as suggested by comments.
4874 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4875 Remove redundant check before calling offset_intervals.
4877 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4879 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4880 current buffer (Bug#12387).
4882 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4884 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4886 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4888 Use a more backwards-compatible timer format (Bug#12430).
4889 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4890 vector element, not from the 4th, since PSECS is now at the end.
4891 (Fcurrent_idle_time): Doc fix.
4893 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4895 Function to mark objects and remove killed buffers at once.
4896 * alloc.c (discard_killed_buffers): Rename to ...
4897 (mark_discard_killed buffers) ... new name. Add marking
4898 of remaining objects. Fix comment. Adjust users.
4899 (mark_object): Do not touch frame buffer lists here.
4900 * frame.c (delete_frame): Reset frame buffer lists here.
4902 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4904 Better workaround for GNOME bug when --enable-gcc-warnings.
4905 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4906 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4907 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4909 Simplify SIGIO usage (Bug#12408).
4910 The code that dealt with SIGIO was crufty and confusing, e.g., it
4911 played tricks like "#undef SIGIO" but these tricks were not used
4912 consistently. Simplify mostly by not #undeffing standard symbols,
4913 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4914 or not as we please) rather than "defined SIGIO" (standard symbol
4915 that we probably shouldn't #undef).
4916 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4917 Modules that need it can include it.
4918 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4919 * dispextern.h (ignore_sigio): New decl.
4920 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4921 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4922 * emacs.c (shut_down_emacs):
4923 * keyboard.c (kbd_buffer_store_event_hold):
4924 Use ignore_sigio rather than invoking 'signal' directly.
4925 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4927 (FIONREAD, SIGIO): Do not #undef.
4928 (tty_read_avail_input): Use #error rather than a syntax error.
4929 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4930 for I_PIPE, used by SETUP_SLAVE_PTY.
4931 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4932 * sysdep.c (croak): Remove; no longer needed. This bit of
4933 temporary code, with Fred N. Fish's comment that it's temporary,
4934 has been in Emacs since at least 1992!
4935 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4936 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4937 * syssignal.h (croak): Remove decl.
4938 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4939 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4940 now that we're termios-only.
4941 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4942 * term.c (dissociate_if_controlling_tty): Use #error rather than
4945 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4946 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4947 to work around GNOME bug 683906.
4948 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4949 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4950 This works around GCC bug 54561.
4952 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4954 More fixes for 'volatile' and setjmp/longjmp.
4955 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4956 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4957 (png_load_body) [HAVE_PNG]:
4958 (jpeg_load_body) [HAVE_JPEG]:
4959 New function, with most of the old parent function's body.
4960 (png_load) [HAVE_PNG]:
4961 (jpeg_load) [HAVE_JPEG]:
4962 Invoke the new function, to avoid longjmp munging our locals.
4963 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4964 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4965 longjmp is passed 2, as the C standard doesn't guarantee this.
4966 Instead, store the failure code into mgr->failure_code.
4968 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4970 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4971 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4972 (syms_of_keyboard): Remove support for unread-command-char.
4974 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4976 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4977 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4978 violation. (Bug#12426)
4980 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4982 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4984 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4986 * eval.c: Add `inhibit-debugger'.
4987 (Qinhibit_debugger): New symbol.
4988 (call_debugger): Bind it instead of Qdebug_on_error.
4989 (maybe_call_debugger): Test Vinhibit_debugger.
4990 (syms_of_eval): Define inhibit-debugger.
4991 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4992 (syms_of_xdisp): Remove inhibit-debug-on-message.
4994 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4996 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4997 If a nonvolatile local variable is written before a _longjmp to
4998 the frame containing the variable, and is read after the _longjmp,
4999 the value read is indeterminate. Some local variables of type
5000 'struct handler' and 'struct catchtag' are used in this way, so
5001 mark each of their slots as volatile if the slot can be set before
5002 _longjmp and read afterwards.
5003 * lisp.h (struct handler): var and chosen_clause are now volatile.
5004 (struct catchtag): val, next, and pdlcount are now volatile.
5006 * bidi.c (bidi_push_it, bidi_pop_it):
5007 * fns.c (copy_hash_table):
5008 * image.c (define_image_type):
5009 * keyboard.c (kbd_buffer_store_event_hold):
5010 * process.c (Fprocess_send_eof):
5011 * xfaces.c (x_create_gc) [HAVE_NS]:
5012 * xgselect.c (xg_select):
5013 Prefer assignment to memcpy when either will do.
5015 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5016 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5017 time an item is removed. No need to mark this function 'inline';
5018 the compiler knows better than we do.
5020 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5022 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5023 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5024 to change_frame_size (Bug#12388).
5025 (windowDidResize:): Pass YES to updateFrameSize.
5027 * nsterm.h: Add delay parameter to updateFrameSize.
5029 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5031 Discard killed buffers from deleted window and frame objects.
5032 This reduces an amount of references to killed buffers and
5033 helps GC to reclaim them faster.
5034 * alloc.c (discard_killed_buffers): New function.
5035 (mark_object): Use it for deleted windows and frames.
5036 (mark_object): If symbol's value is set up for a killed buffer
5037 or deleted frame, restore its global binding.
5038 * data.c (swap_in_global_binding): Add GC notice.
5039 (swap_in_symval_forwarding): Use convenient set_blv_where.
5040 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5041 * window.h: ... to here.
5043 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5045 Convenient macro to check whether the buffer is live.
5046 * buffer.h (BUFFER_LIVE_P): New macro.
5047 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5048 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5050 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5052 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5053 composition cases (Bug#12364).
5055 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5056 overhang of succeeding glyphs overlapping box cursor.
5058 * w32term.c (x_draw_glyph_string): Likewise.
5060 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5062 Simplify, document, and port floating-point (Bug#12381).
5063 The porting part of this patch fixes bugs on non-IEEE platforms
5064 with frexp, ldexp, logb.
5065 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5067 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5068 support, by removing commented-out code and briefly listing the
5069 C89 functions excluded. The commented-out stuff was confusing
5070 maintenance, e.g., we thought we needed cbrt but it was commented out.
5071 (logb): Remove decl; no longer needed.
5072 (isfinite): New macro, if not already supplied.
5073 (isnan): Don't replace any existing macro.
5074 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5075 are present on all C89 platforms.
5076 (Ffrexp): Do not special-case zero, as frexp does the right thing
5078 (Flogb): Do not use logb, as it doesn't have the desired meaning
5079 on hosts that use non-base-2 floating point. Instead, stick with
5080 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5081 frexp, to avoid getting an unspecified result.
5083 * xdisp.c (Qinhibit_debug_on_message): Now static.
5085 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5087 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5088 NSBezierPath (Bug#12131).
5090 2012-09-10 Chong Yidong <cyd@gnu.org>
5092 * fns.c (Fdelq, Fdelete): Doc fix.
5094 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5096 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5097 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5099 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5101 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5102 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5105 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5107 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5108 left fringe if the window has a left margin. This avoids leaving
5109 traces of the cursor because its leftmost pixel is not drawn over.
5111 * dispnew.c (update_window_line): When the left margin area of a
5112 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5113 that screen line. (Bug#12277)
5115 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5117 Assume C89 or later for math functions (Bug#12381).
5118 This simplifies the code, and makes it a bit smaller and faster,
5119 and (most important) makes it easier to clean up signal handling
5120 since we can stop worring about floating-point exceptions in
5121 library code. That was a problem before C89, but the problem
5122 went away many years ago on all practical Emacs targets.
5123 * data.c, image.c, lread.c, print.c:
5124 Don't include <math.h>; no longer needed.
5125 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5126 might be autoconfigured, as that never happens.
5128 * doprnt.c (DBL_MAX_10_EXP):
5129 * print.c (DBL_DIG):
5130 Remove. C89 or later always defines these.
5131 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5132 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5133 (arith_error, domain_error, domain_error2):
5134 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5135 no longer needed -- we simply return what C returns. All uses removed.
5136 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5138 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5139 Remove. All uses expanded, as these macros are no longer used
5140 more than once and are now more trouble than they're worth.
5141 (Ftan): Use tan, not sin / cos.
5142 (Flogb): Assume C89 frexp.
5143 (fmod_float): Assume C89 fmod.
5144 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5145 (init_floatfns): Remove. All uses removed.
5147 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5149 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5150 compositeToPoint for OSX < 10.6 (Bug#12390).
5152 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5154 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5155 This produces more-accurate results.
5157 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5159 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5160 changes (Bug#12088).
5162 2012-09-08 Chong Yidong <cyd@gnu.org>
5164 * syntax.c (Fstring_to_syntax): Doc fix.
5166 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5168 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5169 in the internal border.
5170 (x_set_window_size): Remove static variables and their usage.
5171 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5172 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5173 Remove fringe/internal border adjustment (Bug#11052).
5174 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5175 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5176 (ns_fix_rect_ibw): Remove.
5177 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5178 (ns_dumpglyphs_box_or_relief): Ditto.
5179 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5181 (ns_dumpglyphs_image): Ditto.
5182 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5184 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5185 their usage. Add fringe_extended_p and its use as in other terms.
5186 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5187 scroll bar was removed.
5188 (updateFrameSize): New function.
5189 (windowDidResize): Move code to updateFrameSize and call it.
5191 * nsterm.h (EmacsView): Add updateFrameSize.
5193 2012-09-07 Chong Yidong <cyd@gnu.org>
5195 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5197 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5199 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5201 More signal-handler cleanup (Bug#12327).
5202 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5203 Problem introduced when merging patches. Noted by Eli Zaretskii in
5204 <http://bugs.gnu.org/12327#67>.
5205 * floatfns.c: Comment fix.
5206 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5207 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5208 and anyway the declaration is harmless even if SIGDANGER is not defined.
5209 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5210 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5211 source files not surprisingly expected syssignal.h to define, or
5212 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5213 Include <sys/ioctl.h>, for FIONREAD.
5214 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5215 This eliminates a problem whereby other files mysteriously had
5216 to include "syssignal.h" before including "systty.h" if they
5217 wanted to use "#ifdef SIGIO".
5219 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5221 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5223 * w32.c (sigemptyset): Empty the set.
5224 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5226 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5228 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5230 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5231 (mark_object): Likewise for frame objects.
5233 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5235 * syssignal.h (handle_on_main_thread): Always declare,
5236 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5237 This ports to platforms without HAVE_PTHREAD.
5239 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5241 Signal-handler cleanup (Bug#12327).
5242 Emacs's signal handlers were written in the old 4.2BSD style with
5243 sigblock and sigmask and so forth, and this led to some
5244 inefficiencies and confusion. Rewrite these to use
5245 pthread_sigmask etc. without copying signal sets around. Also,
5246 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5247 'signal', and instead use functions that do not attempt to take
5248 over the system name space. This patch causes Emacs's text
5249 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5250 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5251 Do not include <signal.h> or "syssignal.h", as these
5252 modules do not use signals.
5253 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5254 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5255 Do not include <signal.h>, as "syssignal.h" does that for us now.
5256 * atimer.c (sigmask_atimers): New function.
5257 (block_atimers, unblock_atimers): New functions,
5258 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5260 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5261 no longer needed here.
5262 * emacs.c (main): Inspect existing signal handler with sigaction,
5263 so that there's no need to block and unblock SIGHUP.
5264 * sysdep.c (struct save_signal): New member 'action', replacing
5265 old member 'handler'.
5266 (save_signal_handlers, restore_signal_handlers):
5267 Use sigaction instead of 'signal' to save and restore.
5268 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5269 New function. All users of 'signal' modified to use set_sighandler
5270 if they're writeonly, and to use sys_signal if they're read+write.
5271 (emacs_sigaction_init, forwarded_signal): New functions.
5272 (sys_signal): Remove. All uses replaced by calls to sigaction
5273 and emacs_sigaction_init, or by direct calls to 'signal'.
5274 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5275 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5276 all uses replaced by pthread_sigmask etc. calls.
5277 * syssignal.h: Include <signal.h>.
5278 (emacs_sigaction_init, forwarded_signal): New decls.
5279 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5280 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5281 (sigmask, sys_sigmask): Remove; no longer needed.
5282 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5283 (sigblock, sigunblock, sigfree):
5284 (sigsetmask) [!defined sigsetmask]:
5285 Remove. All uses replaced by pthread_sigmask.
5286 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5287 no longer need to be replaced, and its typical old uses
5288 are now done via emacs_sigaction_init and sigaction.
5289 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5290 (sys_sigdel): Remove; unused.
5291 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5293 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5295 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5296 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5298 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5300 Explicitly mark buffer_defaults and buffer_local_symbols.
5301 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5302 mark_local_symbols here.
5303 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5304 since special buffers aren't marked here any more.
5305 (allocate_buffer): Chain new buffer with all_buffers here...
5306 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5308 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5309 (syms_of_buffer): Remove staticpro of the above.
5310 (init_buffer_once): Set names for buffer_defaults and
5311 buffer_local_symbols.
5313 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5315 Use bool for booleans in font-related modules.
5316 * font.c (font_intern_prop, font_style_to_value)
5317 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5318 (generate_otf_features, font_check_otf_features, font_check_otf)
5319 (font_match_p, font_list_entities, font_at):
5320 * fontset.c (fontset_id_valid_p, reorder_font_vector
5321 (fontset_find_font, Fset_fontset_font)
5322 (face_suitable_for_char_p) [0]:
5323 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5324 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5325 (m17n_flt_initialized, ftfont_shape_by_flt):
5326 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5327 * nsfont.m (nsfont_draw):
5328 * w32font.c (w32font_draw):
5329 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5330 Use bool for booleans.
5331 * font.h: Adjust to above API changes.
5332 (struct font, struct font_driver, struct font_driver_list):
5333 Use bool for booleans.
5334 (struct font): Remove useless member encoding_type.
5336 * fontset.c, xftfont.c: Omit unnecessary static decls.
5338 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5340 * alloc.c (mark_object): Revert window marking code
5341 since it's unsafe for the Fset_window_configuration.
5343 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5345 Fix race conditions with signal handlers and errno (Bug#12327).
5346 Be more systematic about preserving errno whenever a signal
5347 handler returns, even if it's not in the main thread. Do this by
5348 renaming signal handlers to distinguish between signal delivery
5349 and signal handling. All uses changed.
5350 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5351 * data.c (deliver_arith_signal): Rename from arith_error.
5352 * dispnew.c (deliver_window_change_signal): Rename from
5353 window_change_signal.
5354 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5355 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5356 * keyboard.c (deliver_input_available_signal): Rename from
5357 input_available_signal.
5358 (deliver_user_signal): Rename from handle_user_signal.
5359 (deliver_interrupt_signal): Rename from interrupt_signal.
5360 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5361 (deliver_child_signal): Rename from sigchld_handler.
5362 * atimer.c (handle_alarm_signal):
5363 * data.c (handle_arith_signal):
5364 * dispnew.c (handle_window_change_signal):
5365 * emacs.c (handle_fatal_signal, handle_danger_signal):
5366 * keyboard.c (handle_input_available_signal):
5367 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5368 * process.c (handle_pipe_signal, handle_child_signal):
5369 New functions, with the actual signal-handling code taken from the
5370 original respective signal handlers, sans the sporadic attempts to
5371 preserve errno, since that's now done by handle_on_main_thread.
5372 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5373 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5374 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5376 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5377 Move initialization of main_thread to sysdep.c's init_signals.
5378 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5379 our usage, and simplifies the mainline code.
5380 (record_child_status_change): New static function, as a helper
5381 for handle_child_signal, and with most of the old child handler's
5383 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5384 (handle_child_signal): Use the above.
5385 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5386 Moved here from emacs.c.
5387 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5388 code moved here from emacs.c's main function.
5389 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5390 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5391 This lets callers save and restore errno properly.
5393 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5395 Remove redundant or unused things here and there.
5396 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5397 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5398 * editfns.c (Fcompare_buffer_substrings): Likewise.
5399 * frame.h (struct terminal, struct font_driver_list):
5400 Remove redundant declarations.
5401 * window.h (Qleft, Qright): Likewise.
5403 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5405 Do not mark objects from deleted buffers, windows and frames.
5406 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5407 (mark_object): Likewise for windows and frames.
5409 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5411 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5412 buffer_defaults and buffer_local_symbols as valid objects.
5413 Return special value to denote them.
5415 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5417 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5418 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5419 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5420 (file_name_absolute_p, Fsubstitute_in_file_name):
5421 (check_executable, check_writable, Ffile_accessible_directory_p)
5422 (Fset_file_selinux_context, Fdefault_file_modes)
5423 (Finsert_file_contents, choose_write_coding_system)
5424 (Fwrite_region, build_annotations, a_write, e_write)
5426 * filelock.c (boot_time_initialized, get_boot_time)
5427 (get_boot_time_1, lock_file_1, within_one_second):
5428 * floatfns.c (in_float):
5429 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5430 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5431 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5432 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5433 * window.c (compare_window_configurations):
5434 Use bool for booleans.
5435 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5436 (Fdefault_file_modes): Now mode_t, not int, for modes.
5437 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5438 (internal_delete_file): Now returns void, not a (boolean) int,
5439 since nobody was looking at the return value.
5440 * lisp.h, window.h: Adjust to above API changes.
5442 * xdisp.c (set_message): Simplify and reindent last change.
5444 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5446 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5448 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5450 * eval.c (call_debugger): Make the function non-static so that we
5451 can call it from set_message.
5453 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5454 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5456 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5458 Give more-useful info on a fatal error (Bug#12328).
5459 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5460 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5461 of doing the work ourselves.
5462 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5463 do most of the work.
5464 (fatal_error_backtrace): New function, taken from the guts
5465 of the old fatal_error_signal, but with a new option to output
5467 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5468 info about the signal than just its number.
5469 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5470 * sysdep.c: Include <execinfo.h>
5471 (emacs_backtrace): New function, taken partly from the previous
5472 code of the 'die' function.
5473 (emacs_abort): Call fatal_error_backtrace rather than abort.
5475 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5477 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5478 eager (load-time) macro-expansion.
5479 * lisp.mk (lisp): Add macroexp.
5481 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5483 Simplify redefinition of 'abort' (Bug#12316).
5484 Do not try to redefine the 'abort' function. Instead, redo
5485 the code so that it calls 'emacs_abort' rather than 'abort'.
5486 This removes the need for the NO_ABORT configure-time macro
5487 and makes it easier to change the abort code to do a backtrace.
5488 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5489 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5490 Remove; sysdep.c's emacs_abort now takes its place.
5491 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5492 'abort' changed to use 'emacs_abort'.
5493 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5494 (abort) [!defined abort]: Rename to ...
5495 (emacs_abort): ... new name.
5496 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5497 the place of the old 'abort' in emacs.c.
5498 * w32.c, w32fns.c (abort): Do not #undef.
5499 * w32.c (emacs_abort): Rename from w32_abort.
5501 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5503 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5504 offsets[j].dv, since the y axis of the screen coordinates points
5505 down, while the y axis of the font definition coordinates points
5506 up. This fixes display of Arabic diacritics such as KASRA and
5507 KASRATAN. (Bug#11860)
5509 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5511 Be more systematic about _setjmp vs setjmp.
5512 * alloc.c (test_setjmp, mark_stack):
5513 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5514 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5515 (png_load, my_error_exit, jpeg_load):
5516 * process.c (send_process_trap, send_process):
5517 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5518 The underscored versions are up to 30x faster on some hosts.
5519 Formerly, the code used setjmp+longjmp sometimes and
5520 _setjmp+_longjmp at other times, with no particular reason to
5521 prefer setjmp+longjmp.
5523 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5525 Fix minor problem found by static checking.
5526 * buffer.c (Fdelete_all_overlays): Return nil.

5552 EXCLUDE_SUBRS_P. All callers changed.
5553 * dispextern.h, lisp.h: Reflect above API changes.
5554 * firstfile.c (dummy): Use the address of 'main', whose signature
5555 won't change, instead of the address of 'initialize', whose
5556 signature just changed from int to bool.
5557 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5558 * msdos.c (fatal_error_in_progress): ... from here.
5559 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5561 (redisplay_internal, unwind_redisplay): Simply clear
5562 REDISPLAYING_P when unwinding, instead of saving its previous,
5563 always-false value and then restoring it.
5565 Clean up some extern decls.
5566 Mostly, this hoists extern decls out of .c files and into .h files.
5567 That way, we're more likely to catch errors if the interfaces change.
5568 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5569 declare xg_mark_data.
5570 * dispextern.h (x_frame_parm_handlers):
5572 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

5589 * xterm.c (x_frame_parm_handlers):
5590 Remove now-redundant extern decls.
5591 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5592 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5594 * xfaces.c: Remove unnecessary static decls.
5595 * xterm.c (updating_frame): Remove decl of nonexistent object.
5597 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5598 when building globals.h, as the objects that are not built on
5599 this host are not needed to compile C files on this host.
5601 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5603 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5651 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5653 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5654 more than one grapheme cluster passed to the shaper: compute the
5655 offset adjustment values separately for each cluster. (Bug#11860)
5657 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5658 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5659 about implicit conversions from integer to pointer.
5661 2012-09-01 Daniel Colascione <dancol@dancol.org>
5663 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5664 system used too early.
5666 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>

5717 window system declarations.
5719 * frame.h: Move common functions here: set_frame_menubar,
5720 x_set_window_size, x_sync, x_get_focus_frame,
5721 x_set_mouse_position, x_set_mouse_pixel_position,
5722 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5749 * lisp.h (mark_ttys): Remove prototype.
5750 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

5752 the frames which are reachable from Vframe_list.
5753 * term.c (mark_ttys): Remove.
5754 (init_tty): Safely initialize 'top_frame' slot with Qnil.

5783 * lread.c (init_lread): For out-of-tree builds, only add the
5784 source directory's site-lisp dir to the load-path if it exists,
5785 consistent with in-tree builds. (Bug#12302)

5806 Handle click on close button as quit.
5808 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5809 Add window_closed and button_values. Add void as return value for
5810 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5811 Add process_dialog as new member.
5813 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5815 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5945 (code_convert_string, code_convert_string_norecord)
5946 (Fset_coding_system_priority):
5947 * fileio.c (Finsert_file_contents):
5948 Use bool for booleans.
5949 * coding.h, lisp.h: Reflect above API changes.
5950 * coding.c: Remove unnecessary static function decls.
5951 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5952 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5953 not a boolean 'int', since callers never look at the return value.
5954 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5955 * coding.h (decoding_buffer_size, encoding_buffer_size)
5956 (emacs_mule_string_char): Remove unused extern decls.
5957 (struct iso_2022_spec, struct coding_system):
5958 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5959 (struct emacs_mule_spec): Remove unused field 'full_support'.
5960 All initializations removed.
5961 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5963 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5965 Fix spare memory change (Bug#12286).
5966 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5967 (valid_lisp_object_p): Likewise.
5969 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5971 * window.c (Fset_window_configuration): Record any window's old
5972 buffer if it's replaced (see Bug#8789). If the new current
5973 buffer doesn't appear in the selected window, go to its old
5976 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5978 Special MEM_TYPE_SPARE to denote reserved memory.
5979 * alloc.c (enum mem_type): New memory type.
5980 (refill_memory_reserve): Use new type for spare memory.
5981 This prevents live_cons_p and live_string_p from incorrect
5982 detection of uninitialized objects from spare memory as live.
5984 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5987 * Makefile.in (.PHONY): versioclean -> versionclean.
5989 Remove unused external symbols.
5990 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5991 * window.c (Qwindow_valid_p, decode_valid_window):
5992 Now static, not extern.
5993 * data.c (Qinterval): Remove; unused.
5994 (syms_of_data): Do not define 'interval'.
5995 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5996 * window.h (decode_valid_window):
5999 * character.c, charset.c, chartab.c: Use bool for booleans.
6000 * character.c (lisp_string_width, string_count_byte8)
6001 (string_escape_byte8):
6002 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6003 (load_charset_map_from_file, map_charset_chars)
6004 (Fdefine_charset_internal, define_charset_internal)
6005 (Fdeclare_equiv_charset, find_charsets_in_text)
6006 (Ffind_charset_region, char_charset, Fiso_charset):

6008 (sub_char_table_set, sub_char_table_set_range)
6009 (char_table_set_range, optimize_sub_char_table)
6010 (map_sub_char_table):
6011 Use bool for boolean.
6012 * character.c (str_to_unibyte): Omit last boolean argument; it was
6013 always 0. All callers changed.
6014 * character.h, charset.h: Adjust to match previous changes.
6015 * character.h (char_printable_p): Remove decl of nonexistent function.
6016 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6017 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6018 are all boolean, so make them single-bit bitfields.
6020 * lisp.h (ASET): Remove attempt to detect side effects.
6021 It was meant to be temporary and it often doesn't work,
6022 because when IDX has side effects the behavior of IDX==IDX
6023 is undefined. See Stefan Monnier in
6024 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6026 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6028 * lisp.h (functionp): New function (extracted from Ffunctionp).
6029 (FUNCTIONP): Use it.
6030 * eval.c (Ffunctionp): Use it.
6032 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6034 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6035 as that's faster and simpler than static storage. Don't bother
6036 with the g_main_context_query overhead if g_main_context_pending
6037 says no events are pending.
6038 (gfds, gfds_size): Remove these static vars.
6039 (xgselect_initialize): Remove; no longer needed.
6040 All uses and decls removed.
6042 * emacs.c (fatal_error_signal_hook): Remove.
6043 All uses removed. This leftover from old code was always 0.
6045 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6046 * casefiddle.c (casify_object, casify_region):
6047 * casetab.c (set_case_table):
6048 * category.c, category.h (word_boundary_p):
6049 * category.h (CHAR_HAS_CATEGORY):
6050 Use bool for booleans, instead of int.
6052 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6054 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6056 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6058 On assertion failure, print backtrace if available.
6059 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6060 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6061 * Makefile.in (LIB_EXECINFO): New macro.
6064 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6065 * bytecode.c (exec_byte_code):
6066 * callint.c (check_mark, Fcall_interactively):
6067 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6068 (getenv_internal, sync_process_alive, call_process_exited):
6069 * lisp.h (USE_SAFE_ALLOCA):
6070 Use bool for booleans, instead of int.
6071 * lisp.h, process.h: Adjust prototypes to match above changes.
6072 * callint.c (Fcall_interactively): Don't assume the mark's
6073 offset fits in 'int'.
6075 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6077 * buffer.c, buffer.h: Use bool for boolean.
6078 * buffer.c (reset_buffer_local_variables)
6079 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6080 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6081 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6082 (overlay_touches_p, overlay_strings, Foverlay_put)
6083 (report_overlay_modification, call_overlay_mod_hooks):
6084 (mmap_enlarge, mmap_set_vars):
6085 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6086 Use bool for booleans, instead of int.
6087 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6088 since the 1-or-0 return value is always ignored anyway.
6089 (mmap_initialized_p):
6090 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6091 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6093 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6095 * bidi.c: Use bool for boolean.
6096 This is a bit more readable, and makes the text segment of bidi.o
6097 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6098 Presumably it's faster too.
6099 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6101 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6102 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6103 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6104 (bidi_explicit_dir_char, bidi_level_of_next_char)
6105 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6106 Use bool for booleans, instead of int.
6107 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6108 (bidi_unshelve_cache): Adjust decls to match code.
6110 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6112 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6115 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6117 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6118 * atimer.h: Include <stdbool.h>.
6120 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6122 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6123 compile time tests instead of run time tests on systems that do
6125 (FRAME_MAC_P): Remove leftover from deleted code.
6126 * frame.c (syms_of_frame): Remove leftover from deleted code.
6128 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6130 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6132 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6134 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6135 Otherwise, the compiler complains about (A?B:C) where B is void
6136 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6137 (fontset_add): Return void, for FONTSET_ADD.
6139 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6141 * alloc.c: Use bool for booleans.
6142 (gc_in_progress, abort_on_gc)
6143 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6144 (dont_register_blocks) [GC_MALLOC_CHECK]:
6145 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6146 (check_string_bytes, make_specified_string, memory_full)
6147 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6148 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6149 (mark_stack, valid_pointer_p, make_pure_string)
6150 (Fgarbage_collect, survives_gc_p, gc_sweep):
6151 Use bool for booleans, instead of int.
6152 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6153 Remove unused local.
6154 * alloc.c (PURE_POINTER_P):
6155 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6156 * editfns.c (Fformat):
6157 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6159 * fns.c (sweep_weak_table):
6160 * lisp.h (suppress_checking, push_message, survives_gc_p)
6161 (make_pure_string, gc_in_progress, abort_on_gc):
6162 * lread.c (readchar, read1):
6163 * print.c (Fprin1_to_string):
6164 * xdisp.c (push_message):
6165 Use bool for booleans affected directly or indirectly by
6168 Make recently-introduced setters macros.
6169 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6170 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6171 (set_fontset_default, set_fontset_fallback): Rename from their
6172 upper-case counterparts, and make them functions rather than macros.
6173 This is more consistent with the other recently-introduced setters.
6174 These don't need to be inline, since they're local.
6176 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6178 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6179 the loop (Bug#12247).
6181 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6183 * lisp.h (vcopy): Use memcpy rather than our own loop.
6184 This fixes a performance regression introduced by the recent
6185 addition of vcopy. This means 'vcopy' will need to be modified
6186 for a copying collector, but that's OK. Also, tighten the
6187 checking in the assertion.
6189 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6191 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6192 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6193 non-base glyph for the width of the base character, according to
6194 what x_draw_composite_glyph_string_foreground expects.
6195 Generate WADJUST value according to composition_gstring_width's
6196 expectations, to produce correct width of the composed character.
6197 Reverse the sign of the DU offset produced by ScriptPlace.
6199 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6201 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6203 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6205 Avoid direct writes to contents member of struct Lisp_Vector.
6206 * lisp.h (vcopy): New function to copy data into vector.
6207 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6208 * fns.c (Ffillarray): Use ASET.
6209 * keyboard.c (timer_check_2): Use AREF and ASET.
6210 (append_tool_bar_item, Frecent_keys): Use vcopy.
6211 * lread.c (read_vector): Use ASET.
6212 * msdos.c (Frecent_doskeys): Use vcopy.
6213 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6214 (Finternal_merge_in_global_face): Use ASET and vcopy.
6215 * xfont.c (xfont_list_pattern): Likewise.
6217 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6219 * window.c (Fwindow_point): For the selected window always return
6220 the position of its buffer's point.
6221 (Fset_window_point): For the selected window always go in its
6222 buffer to the specified position.
6224 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6226 Setter macros for fontsets.
6227 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6228 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6229 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6232 2012-08-20 Glenn Morris <rgm@gnu.org>
6234 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6235 Don't assume that `ln -f' works.
6237 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6239 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6240 and later about non-assignments with no effect. See discussion at
6241 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6244 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6246 Inline setter functions for Lisp_Objects slots of struct specbinding.
6247 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6250 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6252 * window.c (select_window): Always make selected window's buffer
6255 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6257 Use AREF and ASET for docstrings of category tables.
6258 * category.h (CATEGORY_DOCSTRING): Use AREF.
6259 (SET_CATEGORY_DOCSTRING): Use ASET.
6260 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6262 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6264 Inline setter functions for hash table members.
6265 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6266 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6267 (set_hash_key_and_value, set_hash_index, set_hash_next)
6268 (set_hash_hash): New functions.
6269 * charset.c, fns.c: Adjust users.
6271 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6273 Inline getter and setter functions for per-buffer values.
6274 * buffer.h (per_buffer_default, set_per_buffer_default)
6275 (per_buffer_value, set_per_buffer_value): New functions.
6276 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6277 * buffer.c, data.c: Adjust users.
6279 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6281 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6283 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6285 Rely on <config.h> + <unistd.h> to declare 'environ',
6286 as gnulib does this if the system doesn't.
6287 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6288 Remove declaration. MS-Windows declares it on stdlib.h which is
6289 included by conf_post.h.
6290 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6291 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6292 * vm-limit.c: Include <unistd.h>, for 'environ'.
6294 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6295 (start_of_data): Remove decl; mem-limits.h provides it.
6297 * xdisp.c (handle_invisible_prop): Make it a bit faster
6298 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6300 2012-08-19 Chong Yidong <cyd@gnu.org>
6302 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6305 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6307 * .gdbinit: Use call instead of set when calling a function in the
6310 * data.c (set_internal): Don't use set_blv_found.
6311 (Fkill_local_variable): Likewise.
6313 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6315 * nsfont.m (ns_ascii_average_width): Ensure the string
6316 ascii_printable is initialized with a null-terminated character
6317 array. Otherwise, it can contain undesired extra characters.
6319 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6321 port new setting code to Sun C 5.8 2005/10/13
6322 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6323 Return void, not Lisp_Object. Otherwise, the compiler
6324 complains about (A?B:C) where B is void and C is Lisp_Object
6325 when compiling CHAR_TABLE_SET, due to the recent change to
6326 the API of sub_char_table_set_contents.
6328 2012-08-18 Chong Yidong <cyd@gnu.org>
6330 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6331 for the string case (Bug#3874).
6333 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6335 * buffer.h (BSET): Remove (Bug#12215).
6336 Replace all uses with calls to new setter functions.

6364 * category.c (bset_category_table):
6365 * syntax.c (bset_syntax_table):
6366 New setter functions.
6368 * process.h (PSET): Remove (Bug#12215).

7268 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7269 checking subscripts; problem introduced with the recent
7270 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7271 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7272 since it's used in non-static inline functions now.
7274 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7275 Don't assume buffer size fits in 'int'. Remove unused local.

7301 (INLINE_HEADER_END): New macros.
7302 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7326 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7327 This how ASET and AREF are supposed to work, and makes
7328 it easier to think about future improvements. See
7329 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7330 * charset.h (set_charset_attr): New function.

7711 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
7712 (w32_kbd_patch_key, key_event): Use the codepage returned by
7713 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
7714 (key_event): use uChar.UnicodeChar only if
7715 w32_console_unicode_input is non-zero.

7745 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7746 enumeration constants, as PURE and HEAP are too general, and clash
7747 with other headers and sources, such as gmalloc.c and the
7748 MS-Windows system headers. All users changed.
7750 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7752 Revert last save_excursion_save and save_excursion_restore changes.
7753 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7763 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
7765 Improve GDB symbol export (Bug#12036).
7766 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7767 arms of an 'if', not using conditional expressions; otherwise GDB
7768 complains about the types in the unevaluated arm when the argument
7769 is an integer literal.
7770 (xgetint): Simplify expression.
7771 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7772 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7773 Zaretskii in <http://bugs.gnu.org/12036#13>.
7774 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7775 needed now that we have gdb_make_enums_visible.
7776 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7777 (enum enum_USE_LSB_TAG):
7778 New enum types, packaging up enums that need to be exported to GDB.

7802 * lisp.h (struct Lisp_Excursion): New data type.
7803 (PVEC_EXCURSION): New pseudovector type.
7804 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7805 to deal with it. Adjust comments.

7820 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7821 emacs.c, as this is a more-suitable home. Had this been done earlier
7822 the fix for 12036 would have avoided some of the problems noted in
7823 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7824 would have been more obvious.
7825 * emacs.c: Do not include <verify.h>; no longer needed.
7826 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7827 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7828 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7829 Remove; now done in lisp.h.

7832 (DATA_SEG_BITS): Use it.
7833 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7834 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7835 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7836 not be usable in #if. This simplifies things.
7838 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7840 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7842 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7844 Simplify export of symbols to GDB (Bug#12036).
7845 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7846 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7847 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7848 Adjust to changes in lisp.h and emacs.c, by using
7849 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7850 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7851 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7852 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7853 instead of gdb_valbits.
7854 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7855 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7856 instead of gdb_array_mark_flag.
7857 (xboolvector): Get size from $->size, not $->header.size.
7858 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7859 (xreload, hook-run, hookpost-run): Remove.
7860 * emacs.c: Include <verify.h>.
7861 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7862 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7864 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7865 (gdb_USE_LSB_TAG): New enum constants.
7866 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7867 Also define these as enum constants, so they're visible to GDB.
7868 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7869 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7870 as constants, so they're visible to GDB.

7873 Now enum constants, not macros, so they're visible to GDB.
7874 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7875 more convenient now. All uses changed.
7876 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7877 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7879 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7886 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7887 add argument, tune behavior, and adjust all callers.
7889 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7891 Use typedef for EMACS_INT, EMACS_UINT.
7892 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7893 than macros. This simplifies debugging in the usual case, since
7894 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7895 and it allows expressions involving EMACS_INT casts.
7896 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7898 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7908 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7910 Adjust buffer text indirection counters at the end of Fkill_buffer.
7911 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7912 buffer is definitely dead. This should really fix an issue reported
7913 by Christoph Scholtes again. (Bug#12007).
7914 (init_buffer_once): Initialize indirection counters of
7915 buffer_defaults and buffer_local_symbols (for sanity and safety).
7917 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7919 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7920 and continuation glyphs on tooltip frames, leave them at zero.

7923 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7925 Simplify copy_overlay.
7926 * buffer.c (copy_overlay): Simplify. Use build_marker.

7948 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7950 Swap buffer text indirection counters in Fbuffer_swap_text.
7951 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7952 This avoids crash reported by Christoph Scholtes at
7953 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7955 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7957 * nsmenu.m (Popdown_data): New struct.
7958 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7960 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7961 (initWithContentRect): Make imgView and contentView non-static
7962 and autorelease them. Also autorelease img and matrix (Bug#12005).
7963 (dealloc): Remove (Bug#12005).
7965 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7967 Adjust consing_since_gc when objects are explicitly freed.

7980 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7982 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7983 as it's limited by the amount of memory, not by INT_MAX.
7985 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7987 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7988 in special-event-map. See the discussion at

8047 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8048 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8049 Adjust users accordingly.
8050 * font.h (font_open_by_name): Adjust prototype.

8069 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8070 'for_each_per_buffer_object_at'.
8071 All uses changed. It's better to use upper-case for macros that
8072 cannot be implemented as functions, to give the reader a clue
8073 that they're special.
8075 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8077 * alloc.c (Fgarbage_collect): Tweak docstring.

8118 * intervals.c (merge_interval_right, merge_interval_left):
8119 Do not zero out this interval if it is absorbed by its children,

8123 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8125 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8126 when invoking (make-bool-vector N t) and N is a positive

8641 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
8642 since nothing has defined it on these platforms.

8656 2012-07-11 John Wiegley <johnw@newartisans.com>
8658 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
8659 function attribute, so we only use it if it exists in the
8662 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
8664 Avoid call to strlen in fast_c_string_match_ignore_case.

8711 * s/aix4-2.h (unix): Remove; no longer needed.
8713 EMACS_TIME simplification (Bug#11875).
8714 This replaces macros (which typically do not work in GDB)
8715 with functions, typedefs and enums, making the code easier to debug.
8716 The functional style also makes code easier to read and maintain.
8717 * systime.h: Include <sys/time.h> on all hosts, not just if
8718 WINDOWSNT, since 'struct timeval' is needed in general.
8719 (EMACS_TIME): Now a typedef, not a macro.
8720 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8722 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

8726 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
8727 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8728 which are not functions. All uses rewritten to use:
8729 (make_emacs_time): New function.
8730 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8731 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8732 not functions. All uses rewritten to use the following, respectively:
8733 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8734 (add_emacs_time, sub_emacs_time): New functions.
8735 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8736 * fileio.c (Fcopy_file):
8737 * xterm.c (XTflash): Get the current time closer to when it's used.
8738 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8751 * fileio.c (Fsubstitute_in_file_name):
8752 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8753 (menu_separator_name_p):
8754 * nsmenu.m (ns_update_menubar):
8755 Prefer memcmp to strncmp when either will do.
8756 * nsterm.m: Include <ftoastr.h>.
8758 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8759 Prefer snprintf to strncpy.
8760 * nsterm.m (ns_term_init):
8761 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8762 * nsterm.m (ns_term_init):
8763 Avoid the need for strncpy, by using build_string or
8764 make_unibyte_string directly. Use dtoastr, not snprintf.
8765 * process.c (Fmake_network_process): Diagnose service names that
8766 are too long, rather than silently truncating them or creating
8767 non-null-terminated names.
8768 (Fnetwork_interface_info): Likewise, for interface names.
8769 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8770 Prefer sprintf to strncat.
8771 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8772 Prefer vsnprintf to vsprintf + strncpy.
8774 2012-07-10 Glenn Morris <rgm@gnu.org>
8776 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8777 Clarify fallback case.
8779 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8781 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
8782 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8783 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8784 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8785 where argument type is known to be a Lisp_Cons.
8787 2012-07-10 Tom Tromey <tromey@redhat.com>
8789 * bytecode.c (BYTE_CODE_THREADED): New macro.

8797 Optimize pure C strings initialization.
8798 * lisp.h (make_pure_string): Fix prototype.
8799 (build_pure_c_string): New function, defined as static inline. This
8800 provides a better opportunity to optimize away calls to strlen when
8801 the function is called with compile-time constant argument.
8802 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8803 argument, adjust users accordingly. Use build_pure_c_string where
8805 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8806 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8807 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8809 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8811 Avoid calls to strlen in miscellaneous functions.
8812 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8813 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8814 * lread.c (openp): Likewise.
8816 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8818 Avoid calls to strlen in path processing functions.
8819 * fileio.c (file_name_as_directory): Add comment. Change to add
8820 srclen argument and return the length of result. Adjust users
8822 (directory_file_name): Fix comment. Change to add srclen argument,
8823 swap 1st and 2nd arguments to obey the common convention.
8824 Adjust users accordingly.
8825 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8827 2012-07-10 Glenn Morris <rgm@gnu.org>
8829 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

8833 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8834 * s/gnu.h (DATA_START): Move definitions to configure.
8836 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8837 We include usg5-4-common.h, which defines them both.
8839 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8840 O_RDONLY already includes it).
8842 Stop ns builds setting the EMACSLOADPATH environment variable.
8843 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8844 Now it does not set EMACSLOADPATH, just returns the load-path string.
8845 * nsterm.h: Update accordingly.
8846 * lread.c [HAVE_NS]: Include nsterm.h.
8847 (init_lread) [HAVE_NS]: Use ns_load_path.
8848 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8850 2012-07-09 Glenn Morris <rgm@gnu.org>
8852 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8853 since the included bsd-common.h does so.
8855 Stop ns builds setting the EMACSPATH environment variable.
8856 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8857 (ns_init_paths): Do not set EMACSPATH.
8858 * nsterm.h (ns_exec_path): Add it.
8859 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8862 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8864 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8866 * process.c (wait_reading_process_output): 'waitchannels' was unset
8867 when read_kbd || !NILP (wait_for_cell); fix this.
8869 Add GCC-style 'const' attribute to functions that can use it.
8870 * character.h (char_resolve_modifier_mask):
8871 * keyboard.h (make_ctrl_char):
8872 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8873 (init_character_once, next_almost_prime, init_fns, init_image)
8874 (flush_pending_output, init_sound):
8875 * mem-limits.h (start_of_data):
8876 * menu.h (finish_menu_items):

8879 Declare the dummy function with ATTRIBUTE_CONST.
8880 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8881 Add decls with ATTRIBUTE_CONST.
8883 Minor improvements to make_formatted_string.
8884 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8885 where int is good enough, as vsprintf returns an int.
8886 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8888 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8890 Use make_formatted_string to avoid double length calculation.
8891 * lisp.h (make_formatted_string): New prototype.
8892 * alloc.c (make_formatted_string): New function.
8893 * buffer.c (Fgenerate_new_buffer_name): Use it.
8894 * dbusbind.c (syms_of_dbusbind): Likewise.
8895 * editfns.c (Fcurrent_time_zone): Likewise.
8896 * filelock.c (get_boot_time): Likewise.
8897 * frame.c (make_terminal_frame, set_term_frame_name)
8898 (x_report_frame_params): Likewise.
8899 * image.c (gs_load): Likewise.
8900 * minibuf.c (get_minibuffer): Likewise.

8915 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8917 Move marker debugging code under MARKER_DEBUG.
8918 * marker.c (MARKER_DEBUG): Move marker debugging code under
8919 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8920 for bootstrap with --enable-checking (~3x slowdown reported
8921 by Juanma Barranquero <lekktu@gmail.com>).
8922 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8924 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8926 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8927 See <http://bugs.gnu.org/11825#29>.
8929 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8931 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8932 has no font, use the frame's font. (Bug#11813)
8933 (display_line): Add commentary about displaying truncation glyphs
8935 (produce_special_glyphs): Move here from term.c.
8937 * term.c (produce_special_glyphs): Move to xdisp.c.
8939 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8942 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8944 * xdisp.c (display_line): Avoid warning about implicit declaration
8947 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8949 * lisp.h: Remove empty conditional.
8951 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8953 * lread.c (load_path_check): Now static.
8955 Fix some minor --with-ns problems found by static checking.
8956 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8957 (x_set_font) [!HAVE_X_WINDOWS]:
8958 * image.c (xpm_load_image) [HAVE_NS]:
8959 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8960 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8961 Remove unused local.
8962 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8963 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8964 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8965 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8966 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8967 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8968 Fix pointer signedness problem.
8969 * xfaces.c (FRAME_X_FONT_TABLE):
8970 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8972 2012-07-07 Glenn Morris <rgm@gnu.org>
8974 * lread.c (load_path_check): New function, split from init_lread.
8975 (init_lread): Reorganize. Motivation:
8976 If EMACSLOADPATH is set, check/warn about that rather than the
8977 defaults, which we are not going to use. Hence we can remove
8978 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8979 Don't warn if site-lisp directories are missing.
8980 If not installed, start from a blank load-path, since
8981 PATH_LOADSEARCH refers to the eventual installation directories.
8983 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8985 Support truncation and continuation glyphs on GUI frames, when
8986 fringes are disabled. (Bug#11832)
8987 * xdisp.c (init_iterator): Get dimensions of truncation and
8988 continuation glyphs even if on GUI frames.
8989 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8990 or both, are absent.
8991 (start_display, move_it_in_display_line_to): Handle the case of a
8992 GUI frame without a fringe to display continuation or truncation
8994 (insert_left_trunc_glyphs): Support GUI frames: make sure
8995 truncation glyphs overwrite enough glyphs from the current line to
8996 have sufficient space in pixels.
8997 (display_line): Support truncation and continuation glyphs on GUI
8998 frames. If some spare pixels are left on the line after inserting
8999 the truncation glyphs, fill that space with a stretch glyph of a
9000 suitably computed width.
9002 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9003 produce_glyphs, to support GUI sessions.
9005 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9007 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9009 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9011 Do not require float-time's arg to fit in time_t (Bug#11825).
9012 This works better on hosts where time_t is unsigned, and where
9013 float-time is applied to the (negative) difference between two times.
9014 * editfns.c (decode_time_components): Last arg is now double *,
9015 not int *, and means to store all the result as a double, without
9016 worrying about whether the seconds part fits in time_t.
9017 All callers changed.
9018 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9019 All callers changed.
9020 (Ffloat_time): Do not fail merely because the specified time falls
9021 outside of time_t range.
9023 2012-07-07 Glenn Morris <rgm@gnu.org>
9025 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9050 * w32fns.c (Fx_change_window_property): Doc fix.
9052 * w32fns.c (Fx_window_property): Accept the same arguments as the
9053 X Windows version. Doc fix.
9054 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9056 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9057 Eli Zaretskii <eliz@gnu.org>

9065 * process.c: Avoid unnecessary calls to gettime.
9066 (wait_reading_process_output): Don't get the time of day
9067 when gobbling data immediately and not waiting, as there's no need
9068 for it in that case. This removes a FIXME.
9070 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9072 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9073 is defined (Bug#11768).

9077 Fix marker debugging code.
9078 * marker.c (byte_char_debug_check): Do not perform the check
9079 if buffer is not multibyte.
9080 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):

9083 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9085 Compile marker debugging code only if ENABLE_CHECKING is defined.
9086 * marker.c (byte_char_debug_check, count_markers):
9087 Use only if ENABLE_CHECKING is defined.
9088 (byte_debug_flag): Remove.
9089 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9090 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9092 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9094 Avoid code repetition in marker-related functions.
9095 * marker.c (attach_marker): New function.

9098 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9099 Consistently rename charno to charpos.
9100 (marker_position): Add eassert.
9101 (marker_byte_position): Convert to eassert.

9114 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9115 * composite.c (autocmp_chars): Likewise.
9116 * editfns.c (buildmark): Remove.
9117 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9118 (save_restriction_save): Use build_marker.
9119 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9120 * window.c (save_window_save): Likewise.
9122 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9127 (delete_all_overlays, Fdelete_overlay): Use it.
9128 * minibuf.c (get_minibuffer): Fix comment.
9130 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9132 Port to OpenBSD 5.1 amd64.
9133 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9134 This is needed for OpenBSD, and should be harmless on all BSD systems.
9135 Also, include <sys/sysctl.h>, as it should be available on all
9136 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9137 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9138 use p_pid member, not kp_proc.pid.
9140 2012-07-06 Glenn Morris <rgm@gnu.org>
9142 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9144 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9146 More xmalloc and related cleanup.

9155 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9157 Omit needless casts involving void * pointers and allocation.
9158 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9159 as the former is more robust if P's type is changed.
9160 Prefer xzalloc to xmalloc + memset 0.
9161 Simplify malloc-or-realloc to realloc.
9162 Don't worry about xmalloc returning a null pointer.
9163 Prefer xstrdup to xmalloc + strcpy.
9164 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9166 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9167 alloca of a constant.

9171 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9172 hscroll is larger than the line width. Fixes long and futile
9173 looping inside extend_face_to_end_of_line (on a TTY) producing
9174 glyphs that are not needed and thrown away.
9176 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9178 * marker.c (set_marker_restricted_both): Simplify by using
9181 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9190 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9191 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9192 followed by gtk_box_set_homogeneous (Bug#11768).
9193 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9194 (update_theme_scrollbar_width, xg_create_scroll_bar):
9195 Use gtk_scrollbar_new (Bug#11768).
9196 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9197 (is_box_type): New function (Bug#11768).

9204 * xdisp.c (window_hscroll_limited): New function.
9205 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9206 coordinates when window's hscroll is set to insanely large
9209 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9211 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9272 * fileio.c (time_error_value): Check the right error number.
9273 Problem reported by Troels Nielsen in
9274 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

9278 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9279 This should be fixed in a better way; see Eli Zaretskii in
9280 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9281 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9283 * fileio.c (time_error_value): Rename from special_mtime.
9284 The old name's problems were noted by Eli Zaretskii in
9285 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9287 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9288 This variable's comment says Emacs needs at least one GDB-visible
9289 symbol of type enum pvec_type, to work around GDB problems.
9290 The symbol's value doesn't matter.
9292 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9293 that causes compilation to fail on pre-C99 compilers.
9295 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9297 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9300 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9302 * buffer.c (init_buffer_once): Fix initialization of
9303 headers for buffer_defaults and buffer_local_symbols.
9304 Reported by Juanma Barranquero <lekktu@gmail.com>.

9308 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9309 * lisp.h (enum pvec_type): Use fewer bits.
9310 (PSEUDOVECTOR_SIZE_BITS): New constant.
9311 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9312 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9313 change in pvec_type.

9320 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9321 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9322 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9323 abusing vector->header.next.nbytes.
9324 (live_vector_p): Use PVEC_TYPE.
9325 (mark_object): Adapt code to extract pvectype. Use switch.
9327 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9329 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9330 Tighten new eassert a bit.
9332 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9334 Fix compilation with --enable-gcc-warnings and -O1
9336 * doprnt.c (doprnt): Change type of tem to int, initialize
9337 to avoid compiler warning. Add eassert.
9338 * search.c (simple_search): Initialize match_byte to avoid
9339 compiler warning. Add eassert.
9341 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9343 Avoid weird behavior with large horizontal scrolls.
9344 Without this change, for example, large hscroll values would
9345 mess up Emacs's display on Fedora 15 x86, presumably due to
9346 overflows in int calculations in the display code.
9347 Also, if buffers had long lines, Emacs would freeze.
9348 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9349 (set_window_hscroll): New function, containing the old guts of
9350 Fset_window_hscroll. Return the clipped value.
9351 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9352 This avoids the need to check against PTRDIFF_MAX.
9354 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9356 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

9360 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9362 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9363 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9364 since GCC 4.4.6 issues a bogus warning for them.
9366 Fix bugs in file timestamp newness comparisons.
9367 * fileio.c (Ffile_newer_than_file_p):
9368 * lread.c (Fload): Use full timestamp resolution of files,
9369 not just the 1-second resolution, so that files that are only
9370 slightly newer still count as newer.
9371 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9372 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9374 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9376 * fileio.c: Improve handling of file time marker. (Bug#11852)
9377 (special_mtime): New function.

9379 Use it to set special mtime values consistently.
9381 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9383 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9384 marker for non-existing file. (Bug#11852)
9386 2012-07-03 Glenn Morris <rgm@gnu.org>
9388 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9389 and did not make it into globals.h).
9391 2012-07-03 Tom Tromey <tromey@redhat.com>

9431 * lisp.h (Frandom): Make it visible to C.
9432 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9433 buffer for invisible buffers. (Bug#1229)

9437 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9438 values which aren't power of 2.
9439 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9440 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users

9451 * alloc.c (allocate_vector_block): Remove redundant
9452 calls to mallopt if DOUG_LEA_MALLOC is defined.
9453 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9454 avoid calls to mallopt if zero_vector is returned.
9456 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9458 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9459 is enabled, avoid dereferencing NULL current_sblock if
9462 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9464 Cleanup basic buffer management.
9465 * buffer.h (struct buffer): Change layout to use generic vector
9466 marking code. Fix some comments. Change type of 'clip_changed'
9467 to bitfield. Remove unused #ifndef old.

9474 * alloc.c (allocate_buffer): Adjust to match new layout of
9475 struct buffer. Fix comment.

9478 Lisp area of struct buffer.
9479 (mark_object): Use it. Adjust marking of misc objects
9480 and related comments.
9482 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9484 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9485 wrapper that is not needed because the wrapped code is a no-op (zero
9486 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9487 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9489 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9491 * alloc.c (mark_buffer): Simplify. Remove prototype.
9492 (mark_object): Add comment. Reorganize marking of vector-like
9493 objects. Use CHECK_LIVE for all vector-like objects except buffers
9494 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9495 Avoid redundant calls to mark_vectorlike for bool vectors.
9497 2012-06-30 Glenn Morris <rgm@gnu.org>
9499 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9501 * epaths.in (PATH_SITELOADSEARCH): New.
9502 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9503 This is rather than relying on --enable-locallisppath elements
9504 having "site-lisp" in their names. (Bug#10208#25, 11658)
9506 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9508 * w32proc.c (sys_select): Accept and ignore one more argument.
9510 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9512 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9513 (pselect) [!MS_DOS]: Redirect to sys_select.
9515 * sysdep.c: Don't include dos.h and dosfns.h.
9517 * process.c (sys_select):
9518 * msdos.c (sys_select): Accept one more argument and ignore it.
9520 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9521 adapt data types and code to that.
9524 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9525 which clashes with the gnulib function of the same name.
9527 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9529 * font.c (font_style_to_value, font_style_symbolic)
9530 (font_prop_validate_style): Add type checks for values in
9533 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9535 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9538 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9540 * xdisp.c (try_window_id): Undo last change.
9542 * w32.c (getwd): Adjust commentary about startup_dir.
9543 (init_environment): Always call sys_access, even in non-MSVC
9544 builds. Don't chdir to the directory of the Emacs executable.
9545 This undoes code from 1997 which was justified by the need to
9546 "avoid conflicts when removing and renaming directories". But its
9547 downside was that every relative file name was being interpreted
9548 relative to the directory of the Emacs executable, which can never
9549 be TRT. In particular, it broke sys_access when called with
9550 relative file names.
9551 (sys_access): Map GetLastError to errno.
9553 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9555 * window.h (struct window): Change type of 'fringes_outside_margins'

9565 Add QUIT to make the loop interruptible.
9567 2012-06-29 Glenn Morris <rgm@gnu.org>
9569 * charset.c (init_charset): Make lack of etc/charsets fatal.
9571 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9573 * editfns.c (region_limit): Fix type mismatch.
9575 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

9588 Avoid integer overflow on scroll-left and scroll-right.
9589 * window.c (HSCROLL_MAX): New macro.
9590 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9591 overflow when requested scroll falls outside ptrdiff_t range.

9595 * window.h (struct window): Change type of 'hscroll',
9596 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9597 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9598 Adjust users accordingly.
9599 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9600 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9601 from EMACS_INT to ptrdiff_t.
9602 (make_window): Omit redundant initialization.
9604 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9608 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9610 * window.h (struct window): Change type of 'use_time' and

9677 * alloc.c (allocate_string): Omit intervals initialization.
9678 * alloc.c (make_uninit_multibyte_string): Initialize intervals

9733 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9735 * alloc.c: Remove build_string.
9736 * lisp.h: Define build_string as static inline. This provides
9737 a better opportunity to optimize away calls to strlen when the
9738 function is called with compile-time constant argument.
9739 * image.c (imagemagick_error): Convert to build_string.
9740 * w32proc.c (sys_spawnve): Likewise.
9741 * xterm.c (x_term_init): Likewise.
9743 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9745 Use sprintf return value instead of invoking strlen on result.
9746 In the old days this wasn't portable, since some sprintf
9747 implementations returned char *. But they died out years ago and
9748 Emacs already assumes sprintf returns int.
9749 Similarly for float_to_string.
9750 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9751 * ccl.c (ccl_driver):
9752 * character.c (string_escape_byte8):

9755 * print.c (print_object):
9756 * xdisp.c (message_dolog):
9757 * xfns.c (syms_of_xfns):
9758 Use sprintf or float_to_string result to avoid need to call strlen.
9759 * data.c (Fnumber_to_string):
9760 Use make_unibyte_string, since the string must be ASCII.
9761 * lisp.h, print.c (float_to_string): Now returns int length.
9762 * term.c (produce_glyphless_glyph):
9763 Use sprintf result rather than recomputing it.
9765 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9766 * Makefile.in (ALL_CFLAGS):
9767 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9768 * gmalloc.c, regex.c: Include <config.h> unconditionally.

9772 * dispextern.h (xstrcasecmp): Define to library function
9773 strcasecmp if available.
9774 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

9789 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9791 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9792 sprintf already null-terminates its output.
9794 * xfns.c (x_window): Remove redundant cast.
9796 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9798 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9799 `const char *' to `char *' to avoid compiler warning.
9801 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9803 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9804 instead of truncating it to 63 (admittedly a generous limit).
9806 * process.c: Fix spelling and caps in comments.
9808 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9810 * emacs.c (setpgrp): Remove definition, unused.

9863 * dispnew.c (Fsleep_for, sit_for):
9864 * keyboard.c (kbd_buffer_get_event):
9865 * process.c (Faccept_process_output):
9866 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9867 This improves on the previous patch, which introduced a bug
9868 when time_t is unsigned and as wide as intmax_t.
9869 See <http://bugs.gnu.org/9000#51>.
9871 2012-06-23 Eli Zaretskii <eliz@gnu.org>

9885 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9887 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9888 Privately reported by Herbert J. Skuhra.
9889 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9891 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9892 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9894 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9896 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9897 last argument of make_unibyte_string.

9900 language ID in the event parameters.
9902 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9903 event.code, not the obscure "character set ID".
9905 2012-06-23 Chong Yidong <cyd@gnu.org>
9907 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9909 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9911 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

9934 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9936 Support higher-resolution time stamps (Bug#9000).
9937 The time stamps are only nanosecond-resolution at the C level,
9938 since that's the best that any real-world system supports now.
9939 But they are picosecond-resolution at the Lisp level, as that's
9940 easy, and leaves room for future OS improvements.
9942 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9945 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9946 Don't get current time unless it's needed.
9948 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9949 now provides it if it's absent.
9950 (start_atimer): Port to higher-res time stamps.
9951 Check for time stamp overflow. Don't get current time more
9952 often than is needed.
9954 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9955 Include systime.h, not time.h.
9956 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9958 * dired.c: Include stat-time.h.
9959 (Ffile-attributes): File times now have higher resolution.
9961 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9962 (struct image): Timestamp now has higher resolution.
9964 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9965 has at least microseconds now. All uses removed.
9966 (update_frame, update_single_window, update_window, update_frame_1)
9967 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9968 (duration_to_sec_usec): Remove; no longer needed.
9970 * editfns.c (time_overflow): Now extern.
9971 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9972 (float-time, Fformat_time_string, Fcurrent_time_string)
9973 (Fcurrent_time_zone): Accept and generate higher-resolution
9975 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9976 (decode_time_components, lisp_seconds_argument): New functions.
9977 (make_time): Now static.
9978 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9979 Report an error if the time is invalid, rather than having the caller
9982 * fileio.c: Include <stat-time.h>
9983 (Fcopy_file): Copy higher-resolution time stamps.
9984 Prefer to set the time stamp via a file descriptor if that works.
9985 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9986 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9987 (Fvisited_file_modtime, Fset_visited_file_modtime):
9988 Support higher-resolution time stamps.

9995 (lookup_image): Port to higer-resolution time stamps.
9997 * keyboard.c (start_polling, bind_polling_period):
9998 Check for time stamp overflow.
9999 (read_char, kbd_buffer_get_event, timer_start_idle)
10000 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10001 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10002 Port to higher-resolution time stamps. Do not assume time_t is signed.
10003 (decode_timer): New function. Timers are now vectors of length 9,
10004 not 8, to accommodate the picosecond component.
10005 (timer_check_2): Use it.
10007 * nsterm.m (select_timeout, timeval_subtract): Remove.
10008 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10009 as they're a bit more accurate and handle overflow better.
10010 (ns_select): Change prototype to be compatible with pselect.
10011 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10012 * nsterm.h (ns_select): Adjust prototype.
10014 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10015 us-resolution time stamps.

10029 (wait_reading_process_output):
10030 Port to ns-resolution time stamps.
10031 (Faccept_process_output, wait_reading_process_output):
10032 Check for time stamp overflow. Do not assume time_t is signed.
10033 (select_wrapper): Remove; we now use pselect.
10034 (Fprocess_attributes): Now generates ns-resolution time stamps.
10036 * sysdep.c: Include utimens.h. Don't include utime.h
10037 or worry about struct utimbuf; gnulib does that for us now.
10038 (gettimeofday): Remove; gnulib provides a substitute.
10039 (make_timeval): New function.
10040 (set_file_times): Now sets ns-resolution time stamps.
10041 New arg FD; all uses changed.

10044 Now returns ns-resolution time stamp. All uses changed.
10045 Check for time stamp overflow.
10047 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10048 provides a substitute now.
10050 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10051 since it guarantees struct timespec.
10052 (EMACS_TIME): Now struct timespec, so that we can support
10053 ns-resolution time stamps.
10054 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10055 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10056 (EMACS_USECS): Remove.
10057 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10058 so multiply the arg by 1000 before storing it.
10059 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10061 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10068 (make_timeval, make_lisp_time, decode_time_components): New decls.
10069 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10070 that it mishandled time_t overflow. You can't compare by subtracting!
10071 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10072 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10074 * term.c: Include <sys/time.h>.
10075 (timeval_to_Time): New function, for proper overflow wraparound.
10076 (term_mouse_position, term_mouse_click): Use it.
10078 * undo.c (record_first_change): Support higher-resolution time stamps
10079 in the undo buffer.
10080 (Fprimitive_undo): Use them when restoring time stamps.
10082 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10083 (w32_get_internal_run_time):
10084 Port to higher-resolution Emacs time stamps.
10085 (ltime): Now accepts single 64-bit integer, as that's more convenient
10088 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10090 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10091 for compatibility with pselect. Support ns-resolution time stamps.
10093 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10095 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10096 Check for time stamp overflow, and support ns-resolution time stamps.
10098 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10099 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10100 (timeval_subtract): Remove; no longer needed.
10101 (XTflash, XTring_bell, x_wait_for_event):
10102 Port to ns-resolution time stamps. Don't assume time_t is signed.

10108 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10110 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10111 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10112 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10113 staticidx goes up to 1597 out of 1600 = 0x640.)
10115 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10117 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10118 Otherwise, the umask might be mistakenly 0 while handling input signals.
10120 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10122 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10129 access to `contents' member of Lisp_Vector objects with AREF and ASET
10132 2012-06-19 Chong Yidong <cyd@gnu.org>
10134 * frame.c (delete_frame): When selecting a frame on a different
10135 text terminal, do not alter the terminal's top-frame.

10138 frame's selected window and its terminal's top-frame.
10139 (unwind_format_mode_line): Restore them.
10140 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10142 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10143 since tty frames can be explicitly named.
10144 (prepare_menu_bars): Likewise.
10146 * term.c (Ftty_top_frame): New function.
10148 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

10151 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10152 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10153 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10154 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10161 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10163 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10164 gets killed during executing of this function (Bug#11665).
10165 Try to always return Qt when the buffer has been actually killed.
10166 (Vkill_buffer_query_functions): In doc-string say that functions
10167 run by this hook should not change the current buffer.
10169 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10171 Fix recently-introduced process.c problems found by static checking.

10189 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
10191 * lisp.h (eassert): Assume C89 or later.
10192 This removes the need for CHECK.
10193 (CHECK): Remove. Its comments about always evaluating its
10194 argument were confusing, as 'eassert' typically does not evaluate
10197 * coding.c (produce_chars): Use ptrdiff_t, not int.
10199 * xterm.c (x_draw_underwave): Check for integer overflow.
10200 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10387 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10388 Use an inline function on all platforms when using the union type,
10389 since this is simpler and 'static inline' can be used portably

10506 adjust comment accordingly.
10507 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10508 to denote vector blocks. Adjust users (live_vector_p,

10531 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10533 * doprnt.c (doprnt): Truncate multibyte char correctly.
10534 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10535 would mishandle a string argument "Xc" if X was a multibyte
10536 character of length 2: it would truncate after X's first byte
10537 rather than including all of X.
10539 2012-06-06 Chong Yidong <cyd@gnu.org>
10541 * buffer.c (word_wrap): Doc fix.

10588 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10590 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10591 Convert pctcpu and pctmem to Lisp float properly.
10592 Let the compiler fold better, as 100.0/0x8000 is exact.
10594 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10596 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10599 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

10603 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10605 For a 'struct window', replace some Lisp_Object fields to
10606 bitfields where appropriate, remove unused fields.
10607 * window.h (struct window): Remove unused 'last_mark_x' and
10608 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10609 change its type from Lisp_Object to bitfield.
10610 Change type of 'force_start', 'optional_new_start',
10611 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10612 fields from Lisp_Object to bitfield. Adjust users accordingly.
10614 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10616 Pacify gcc -Wdouble-precision when using Xaw.
10617 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10618 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10619 Use 'float' consistently, rather than 'float' in most places
10620 and 'double' in a couple of places.
10622 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10624 * xdisp.c (handle_stop): Detect whether we have overlay strings
10625 loaded by testing it->current.overlay_string_index to be
10626 non-negative, instead of checking whether n_overlay_strings is
10627 positive. (Bug#11587)
10629 2012-05-31 Chong Yidong <cyd@gnu.org>
10631 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10635 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10637 * search.c (search_buffer): Remove calls to
10638 r_alloc_inhibit_buffer_relocation, as it is now called by
10639 maybe_unify_char, which was the cause of relocation of buffer text
10642 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10644 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10645 for the duration of call to load_charset, to avoid problems with
10646 callers of maybe_unify_char that access buffer text through C
10649 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10650 decrement the inhibition flag, instead of just setting or
10653 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10655 Remove obsolete '#define static' cruft.
10656 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10657 This #undef was "temporary" in 2000; it is no longer needed
10658 now that '#define static' has gone away.
10659 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10660 (gray_bitmap_bits): Remove; no longer needed.
10661 All uses replaced with definiens.
10662 * xterm.c: Include "bitmaps/gray.xbm".
10664 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

10667 The following changes affect the code only when profiling.
10668 * dispnew.c (__executable_start): Rename from safe_bcopy.
10669 Define only on platforms that need it.
10670 * emacs.c: Include <sys/gmon.h> when profiling.
10671 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10672 (__executable_start): Remove decl, since lisp.h does it now.
10673 (safe_bcopy): Remove decl; no longer has that name.
10674 (main): Coalesce #if into single bit of code, for simplicity.
10675 Cast pointers to uintptr_t, since standard libraries want integers
10677 * lisp.h (__executable_start): New decl.
10679 2012-05-31 Glenn Morris <rgm@gnu.org>
10681 * image.c (Fimagemagick_types): Doc fix.

10704 Do not create empty overlays with the evaporate property (Bug#9642).
10705 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10706 Bug#9642, but explicitly check that the buffer the overlay would
10707 be moved to is live and rearrange lines to make sure that errors
10708 will not put the overlay in an inconsistent state.
10709 (Fdelete_overlay): Cosmetics.
10711 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10713 * w32term.c (my_bring_window_to_top): New function.
10714 (x_raise_frame): Use handle returned by DeferWindowPos, which
10715 could be different from the original one.
10716 Call my_bring_window_to_top instead of my_set_foreground_window.

10725 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10727 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10728 This avoids undefined behavior that might cause the eassert
10729 to not catch an out-of-range value.
10731 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10733 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

10747 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10748 Only r_alloc_inhibit_buffer_relocation needed to be added;
10749 the others were already declared.
10751 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10752 before checking whether it's out of range. Put the check inside
10754 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10756 2012-05-27 Ken Brown <kbrown@cornell.edu>
10758 * callproc.c (Fcall_process): Restore a line that was accidentally
10759 commented out in the 2011-02-13 change (bug#11547).

10763 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10764 defined on ralloc.c.
10766 * buffer.c [REL_ALLOC]: Remove prototypes of

10768 they are now on lisp.h.
10770 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10772 * search.c (search_buffer): Use it to inhibit relocation of buffer
10773 text while re_search_2 is doing its job, because re_search_2 is
10774 passed C pointers to buffer text. (Bug#11519)
10776 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10777 Update value to 24.
10779 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10780 state after an additional call to move_it_in_display_line_to, keep
10781 the values of it->max_ascent and it->max_descent found for the
10783 (pos_visible_p): Revert the comparison against bottom_y to what it
10784 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10787 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10789 Fix coding-related core dumps with gcc -ftrapv.
10790 The code was computing A - B, where A and B are pointers, and B is
10791 random garbage. This can lead to core dumps on platforms that
10792 have special pointer registers, and it also leads to core dumps on
10793 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10794 A - B only when B is initialized properly.
10795 * coding.c (coding_set_source, coding_set_destination): Return void.
10796 (coding_change_source, coding_change_destinations): New functions,
10797 with the old behaviors of coding_set_source and coding_set_destination.

10808 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10810 * w32console.c: Include window.h.
10811 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10813 (initialize_w32_display): Initialize mouse-highlight data.
10815 * w32inevt.c: Include termchar.h and window.h.
10816 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10817 moves, call note_mouse_highlight. If help_echo changed, call
10818 gen_help_event to produce help-echo message in the echo area.
10819 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10822 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10824 * lread.c (read1): Simplify slightly to avoid an overflow warning
10825 with GCC 4.7.0 on x86-64.
10827 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10829 * bidi.c (bidi_mirror_char): Revert last change: an int is
10830 definitely wide enough here.

10840 (make_string_from_bytes, make_specified_string)
10841 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10842 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10844 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10845 (allocate_pseudovector):
10846 Use int, not EMACS_INT, where int is wide enough.
10847 (inhibit_garbage_collection, Fgarbage_collect):
10848 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10849 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10850 int might not be wide enough.
10851 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10852 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10853 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10854 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10855 (bidi_level_of_next_char, bidi_move_to_visually_next):

10857 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10858 (Fkill_buffer, Fset_buffer_major_mode)
10859 (advance_to_char_boundary, Fbuffer_swap_text)
10860 (Fset_buffer_multibyte, overlays_at, overlays_in)
10861 (overlay_touches_p, struct sortvec, record_overlay_string)
10862 (overlay_strings, recenter_overlay_lists)
10863 (adjust_overlays_for_insert, adjust_overlays_for_delete)
10864 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)

10866 (Foverlay_recenter, last_overlay_modification_hooks_used)
10867 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10868 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10869 (validate_region): Omit unnecessary test for b <= e,
10870 since that's guaranteed by the previous test.
10871 (adjust_overlays_for_delete): Avoid pos + length overflow.
10872 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10873 (report_overlay_modification):
10874 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10875 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10876 Omit pointer cast, which isn't needed anyway, and doesn't work
10877 after the EMACS_INT -> ptrdiff_t change.
10878 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.

10883 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10884 not int, to avoid needless 32-bit limit on 64-bit hosts.
10885 (exec_byte_code): Use tighter memory-full test, one that checks
10886 for alloca overflow. Don't compute the address of the object just
10887 before an array, as that's not portable. Use EMACS_INT, not
10888 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10889 * callint.c (Fcall_interactively):
10890 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10891 * callproc.c (call_process_kill, Fcall_process):
10892 Don't assume pid_t fits into an Emacs fixnum.

10901 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10902 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10903 (casify_object): Avoid integer overflow when overallocating buffer.
10904 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10905 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10906 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10907 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10908 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

10911 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10912 For CCL_MapSingle, check that content and value are in int range.
10913 (ccl_driver, Fregister_code_conversion_map):
10914 Check that Vcode_version_map_vector is a vector.
10915 (resolve_symbol_ccl_program): Check that vector header is in range.
10916 Always copy the vector, so that we can check its contents reliably
10917 now rather than having to recheck each instruction as it's being
10918 executed. Check that vector words fit in 'int'.
10919 (ccl_get_compiled_code, Fregister_ccl_program)
10920 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10921 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

10923 contents are in range.
10924 (Fccl_execute_on_string): Check that status is in range.
10925 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10926 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10927 Accept and return EMACS_INT, not int, because callers can pass values
10928 out of 'int' range.

10934 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10945 Remove now-unnecessary CHECK_NATNUMs.
10946 (Fdefine_charset_internal): Check ranges here, more carefully.
10947 Don't rely on undefined behavior with signed left shift overflow.
10948 Don't assume unsigned int fits into fixnum, or that fixnum fits
10949 into unsigned int. Don't require max_code to be a valid fixnum;
10950 that's not true for gb10830 4-byte on a 32-bit host. Allow
10951 invalid_code to be a cons, for the same reason. Require code_offset
10952 to be a character. Avoid int overflow if max_char is close
10954 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10955 this is intended anyway and avoids some undefined behavior.
10956 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10957 INDEX_TO_CODE_POINT, as that's what it expects.
10958 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10959 * charset.h (DECODE_CHAR): Return int, not unsigned;
10960 this is what was intended anyway, and it avoids undefined behavior.

10962 integer-overflow issues.
10963 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10964 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10965 where the argument is EMACS_INT, and this behavior is not intended.
10966 * chartab.c (Fmake_char_table, Fset_char_table_range)
10967 (uniprop_get_decoder, uniprop_get_encoder):
10968 Don't assume fixnum fits in int.
10969 * cmds.c (move_point): New function, that does the gist of
10970 Fforward_char and Fbackward_char, but does so while checking
10971 for integer overflow more accurately.
10972 (Fforward_char, Fbackward_char): Use it.
10973 (Fforward_line, Fend_of_line, internal_self_insert)
10974 (internal_self_insert):
10975 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11577 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):

11579 Use int, not unsigned, since we prefer signed and the signedness
11580 doesn't matter here.
11581 (get_next_display_element, next_element_from_display_vector):
11582 Use int, not EMACS_INT, when int is wide enough.

11584 overflow checking on durations.
11585 * xfaces.c (Fbitmap_spec_p):

11622 * xterm.c (x_x_to_emacs_modifiers):
11623 Don't assume EMACS_INT overflows nicely into int.
11624 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
11625 may come from Lisp.
11626 (handle_one_xevent): NATNUMP can eval its arg twice.
11627 (x_connection_closed):
11628 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11629 * xterm.h: Adjust decls to match defn changes elsewhere.
11630 (struct scroll_bar): Use struct vectorlike_header

11634 2012-05-25 Glenn Morris <rgm@gnu.org>
11636 * lisp.mk (lisp): Update for more files being compiled now.
11638 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11640 * lread.c: Remove `read_pure' which makes no difference.
11641 (read_pure): Remove var.
11642 (unreadpure): Remove function.
11643 (readevalloop): Don't call read_list with -1 flag.
11644 (read1, read_vector): Don't test read_pure any more.
11645 (read_list): Simplify.
11647 * fileio.c, character.h: Minor style tweaks.

11653 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
11655 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
11656 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11658 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11661 This directory predates autoconf and is no longer needed nowadays.
11662 Move its few remaining bits of functionality to where they're needed.
11663 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
11664 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
11665 * m/template.h: Remove.
11666 * Makefile.in (M_FILE): Remove. All uses removed.
11667 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11668 * lisp.h (USE_LSB_TAG):
11669 * mem-limits.h (EXCEEDS_LISP_PTR):
11670 Use VAL_MAX, not VALBITS, in #if.
11671 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11672 (EMACS_UINT): Define unconditionally now.
11673 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11674 (BITS_PER_EMACS_INT): New constants, replacing
11675 what used to be in config.h, but not useful in #if.
11676 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11677 define them any more.
11678 (VAL_MAX): New macro.
11680 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11681 BITS_PER_EMACS_INT, in #if.
11682 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11683 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11684 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11685 * s/ms-w32.h (DATA_START):
11686 Move here from removed file m/intel386.h.
11687 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11688 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11690 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11692 Assume C89 or later.
11693 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11694 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11696 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

11702 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11703 * xterm.c (input_signal_count): Assume volatile works.
11705 2012-05-21 Ken Brown <kbrown@cornell.edu>
11707 * xgselect.c (xg_select): Fix first argument in call to 'select'
11710 2012-05-20 Ken Brown <kbrown@cornell.edu>
11712 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11713 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11715 2012-05-19 Ken Brown <kbrown@cornell.edu>
11717 * xfns.c (x_in_use): Remove `static' qualifier.
11718 * xterm.h (x_in_use): Declare.
11719 * xgselect.c: Include xterm.h.
11720 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11721 and `display_arg' (bug#9754).
11723 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11725 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11727 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11728 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11730 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11732 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11734 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11735 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11737 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11738 reference to image_cache->refcount.
11739 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11741 2012-05-17 Juri Linkov <juri@jurta.org>
11743 * search.c (Fword_search_regexp, Fword_search_backward)
11744 (Fword_search_forward, Fword_search_backward_lax)
11745 (Fword_search_forward_lax): Move functions to isearch.el
11746 (bug#10145, bug#11381).
11748 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11750 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11752 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11754 * lread.c (init_obarray): Declare Qt and Qnil as special.
11756 2012-05-14 Glenn Morris <rgm@gnu.org>
11758 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11759 Put "libexec" before "bin", for the sake of init_callproc_1.
11761 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11763 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11765 * unexaix.c: Port to more-recent AIX compilers.
11766 (report_error, report_error_1, make_hdr, copy_sym)
11767 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11768 Make arguments const char *, not char *, to avoid violations of C
11769 standard and to fix some AIX warnings reported by Gilles Pion.
11771 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11773 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11774 already have overlays loaded.
11775 (handle_single_display_spec): Before returning without displaying
11776 fringe bitmap, synchronize the bidi iterator with the main display
11777 iterator, by calling iterate_out_of_display_property.
11778 (iterate_out_of_display_property): Detect buffer iteration by
11779 testing that it->string is a Lisp string.
11780 (get_next_display_element): When the current object is exhausted,
11781 and there's something on it->stack, call set_iterator_to_next to
11782 proceed with what's on the stack, instead of returning zero.
11783 (set_iterator_to_next): If called at the end of a Lisp string,
11784 proceed to consider_string_end without incrementing string
11785 position. Don't increment display vector index past the end of
11786 the display vector. (Bug#11417)
11787 (pos_visible_p): Don't report a position visible when move_it_to
11788 stopped at the last line of window, which happens to be scanned
11789 backwards by the bidi iteration. (Bug#11464)
11791 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11793 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11794 and right-margin display specs even if the spec is invalid or we
11795 are on a TTY, and thus unable to display on the fringes.
11796 That's because the text with the property will not be displayed anyway,
11797 so we need to signal to the caller that this is a "replacing"
11798 display spec. This fixes display when the spec is invalid or we
11801 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11803 * unexaix.c (make_hdr): Fix typo in prototype.
11804 This bug broke the build on AIX. Problem reported by Gilles Pion.
11806 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11808 * keyboard.c (kbd_buffer_get_event): Read special events also in
11809 batch mode. (Bug#11415)
11811 2012-05-12 Glenn Morris <rgm@gnu.org>
11813 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11815 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11817 * lisp.mk (lisp): Add newcomment.elc.
11819 2012-05-12 Glenn Morris <rgm@gnu.org>
11821 * Makefile.in (MKDIR_P): New, set by configure.
11822 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11824 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11826 Remove unused function hourglass_started.
11827 * dispextern.h (hourglass_started):
11828 * w32fns.c (hourglass_started):
11829 * xdisp.c (hourglass_started): Remove.
11831 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11833 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11834 Update dependencies.
11836 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11838 * xgselect.c (xg_select): Put maxfds+1 into a var.
11839 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11841 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11843 2012-05-10 Dave Abrahams <dave@boostpro.com>
11845 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11846 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11848 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11850 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11851 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11852 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11853 Initialize xd_registered_buses.
11855 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11857 Untag more efficiently if USE_LSB_TAG.
11858 This is based on a proposal by YAMAMOTO Mitsuharu in
11859 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11860 For an admittedly artificial (nth 8000 longlist) benchmark on
11861 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11862 Emacs's overall text size by 1%.
11863 * lisp.h (XUNTAG): New macro.
11864 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11865 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11866 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11867 * eval.c (Fautoload):
11868 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11869 * frame.h (XFRAME): Use XUNTAG.
11871 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11872 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11873 Remove unportable assumptions about print widths of types like
11875 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11876 intptr_t when converting between pointer and integer, to avoid GCC
11877 warnings about wrong width.
11879 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11881 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11882 stack for each reader_thread, instead of defaulting to 8MB
11883 determined by the linker. This avoids failures in creating
11884 subprocesses on Windows 7, see the discussion in this thread:
11885 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11887 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11889 Fix up display of the *Minibuf-0* buffer in the mini window.
11890 * keyboard.c (read_char): Don't clear the echo area if there's no
11892 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11893 contents of *Minibuf-0*) if there's no message displayed in its stead.
11895 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11897 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11900 2012-05-06 Chong Yidong <cyd@gnu.org>
11902 * lisp.mk (lisp): Update.
11904 2012-05-05 Jim Meyering <meyering@redhat.com>
11906 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11908 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11910 * data.c (PUT_ERROR): New macro.
11911 (syms_of_data): Use it. Add new error type `user-error'.
11912 * undo.c (user_error): New function.
11913 (Fprimitive_undo): Use it.
11914 * print.c (print_error_message): Adjust print style for `user-error'.
11915 * keyboard.c (user_error): New function.
11916 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11918 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11920 Do not limit current-time-string to years 1000..9999.
11921 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11922 (Fcurrent_time_string): Support any year that is supported by the
11923 underlying localtime representation. Don't use asctime, as it
11924 has undefined behavior for years outside the range -999..9999.
11926 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11928 Fix race conditions involving setenv, gmtime, localtime, asctime.
11929 Without this fix, interrupts could mess up code that uses these
11930 nonreentrant functions, since setting TZ invalidates existing
11931 tm_zone or tzname values, and since most of these functions return
11932 pointers to static storage.
11933 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11934 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11935 Grow the critical sections to include not just invoking
11936 localtime/gmtime, but also accessing these functions' results
11937 including their tm_zone values if any, and any related TZ setting.
11938 (format_time_string): Last arg is now struct tm *, not struct tm **,
11939 so that the struct tm is saved in the critical section.
11940 All callers changed. Simplify allocation of initial buffer, partly
11941 motivated by the fact that memory allocation needs to be outside
11942 the critical section.
11944 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11946 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11947 with RESET_INTERVAL.
11949 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11950 Remove duplicated buffer name initialization.
11952 2012-05-02 Jim Meyering <jim@meyering.net>
11954 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).

11958 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11960 * xdisp.c (pos_visible_p): If already at a newline from the
11961 display string before the 'while' loop, don't walk back the glyphs
11962 from it3.glyph_row. Solves assertion violation when the display
11963 string begins with a newline (egg.el). (Bug#11367)
11965 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>

11973 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11974 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11975 All were removed before 23.1.
11977 * dispnew.c: Remove HAVE_LIBNCURSES test;
11978 it is always true on relevant platforms.
11980 * Makefile.in (LD_SWITCH_X_SITE_RPATH):

11993 Do not avoid creating empty evaporating overlays (Bug#9642).
11994 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11995 That is, do not delete an evaporating overlay if it becomes
11996 empty after its bounds are adjusted to fit within its buffer.
11997 This fix caused other problems, and I'm reverting it until we get
11998 to the bottom of them.
12000 2012-04-27 Chong Yidong <cyd@gnu.org>
12002 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12004 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12006 * xdisp.c (pos_visible_p): If the window start position is beyond
12007 ZV, start the display from buffer beginning. Prevents assertion
12008 violation in init_iterator when the minibuffer window is scrolled
12009 via the scroll bar.
12011 * window.c (window_scroll_pixel_based): Likewise.
12013 2012-04-27 Chong Yidong <cyd@gnu.org>

12020 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12022 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12024 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12025 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12027 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12029 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12030 display element, check also the underlying string or buffer
12031 character. (Bug#11341)
12033 * w32menu.c: Include w32heap.h.
12034 (add_menu_item): If the call to AppendMenuW (via
12035 unicode_append_menu) fails, disable Unicode menus only if we are
12036 running on Windows 9X/Me.
12038 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12040 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12041 (xgetint): Add missing shift for LSB tags.
12043 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12045 * keyboard.c (read_char): Don't wipe echo area for select window

12057 now a cons (bug#11311).
12059 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12061 Do not create empty overlays with the evaporate property (Bug#9642).
12062 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12063 if it becomes empty after its bounds are adjusted to fit within
12064 its buffer. Without this fix, in a nonempty buffer (let ((o
12065 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12066 yields an empty overlay that has the evaporate property, which is
12067 not supposed to happen.

12184 * sysdep.c [__FreeBSD__]: Minor cleanups.
12185 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12186 Use Emacs indenting style more consistently. Avoid some casts.

12201 It is never used otherwise.
12203 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12205 * print.c (print_preprocess): Only check print_depth if print-circle

12272 (NEED_MEM_INSERT): New macro.
12273 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.

12389 `gnutls_handshakes_tried' process member, and
12390 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12391 attempts per process (connection).
12393 2012-04-09 Chong Yidong <cyd@gnu.org>
12395 * eval.c (Fuser_variable_p, user_variable_p_eh)
12396 (lisp_indirect_variable): Functions deleted.
12397 (Fdefvar): Caller changed.

12400 * minibuf.c (Fread_variable): Callers changed.
12402 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12404 * xdisp.c (set_cursor_from_row): If the display string appears in
12405 the buffer at position that is closer to point than the position
12406 after the display string, display the cursor on the first glyph of
12407 the display string. Fixes cursor display when a 'display' text
12408 property immediately follows invisible text. (Bug#11094)
12410 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12412 composite.c: use 'double' consistently
12413 * composite.c (get_composition_id): Use 'double' consistently
12414 instead of converting 'float' to 'double' and vice versa; this is
12415 easier to understand and avoids a GCC warning.
12417 2012-04-09 Glenn Morris <rgm@gnu.org>
12419 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12420 preparation for dumping it with emacs. (Bug#4789)
12421 (leimdir): New variable.
12422 ($(leimdir)/leim-list.el): New rule.
12423 (emacs$(EXEEXT)): Depend on leim-list.el.

12441 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12442 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12443 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12444 objects, as mark_maybe_pointer will catch them otherwise.
12445 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12446 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
12448 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12450 Fix typo that broke non-Windows builds.

12453 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12455 Support building on MS-Windows with libxml2.
12457 * makefile.w32-in (OBJ2): Add xml.$(O).
12458 (GLOBAL_SOURCES): Add xml.c.
12459 ($(BLD)/xml.$(O)): New dependency list.
12461 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.

12463 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12464 [!WINDOWSNT]: New macros.
12465 (init_libxml2_functions, libxml2_loaded_p): New functions.
12466 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12467 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12468 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12469 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12471 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12472 Call init_libxml2_functions before calling libxml2 functions.
12473 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12475 * emacs.c: Don't include libxml/parser.h.
12476 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12477 xmlCleanupParser directly.
12479 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12481 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12483 * indent.c (Fvertical_motion): If there is a display string at
12484 point, use it.vpos to compute how many lines to backtrack after
12485 move_it_to point. (Bug#11133)
12487 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12489 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12490 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12491 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12492 macros related to unification of CJK characters. For the details,
12493 see the discussion following the message here:
12494 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12496 2012-04-04 Chong Yidong <cyd@gnu.org>
12498 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12500 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12502 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12503 instead of alloca. (Bug#11138)
12505 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12507 * w32menu.c (is_simple_dialog): Properly check lisp types.
12510 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12512 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12513 position we get to after a call to move_it_to fails the
12514 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12515 only if we wind up in a string from display property. (Bug#11063)
12517 * window.c (Fdelete_other_windows_internal): Invalidate the row
12518 and column information about mouse highlight, so that redisplay
12519 restores it after reallocating the glyph matrices. (Bug#7464)
12521 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12522 string comes from a `display' text property, use the buffer
12523 position of that property as if we actually saw that position in
12525 (move_it_by_lines): Remove the assertion that
12526 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12527 violated when there's a before-string at the beginning of a line.
12530 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12532 * xdisp.c (append_space_for_newline): If the default face was
12533 remapped, use the remapped face for the appended newline.
12534 (extend_face_to_end_of_line): Use the remapped default face for
12535 extending the face to the end of the line.
12536 (display_line): Call extend_face_to_end_of_line when the default
12537 face was remapped. (Bug#11068)
12539 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12541 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12543 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12545 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12547 2012-03-27 Glenn Morris <rgm@gnu.org>
12549 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12552 2012-03-26 Kenichi Handa <handa@m17n.org>
12554 * dispextern.h (struct glyph): Fix previous change. Change the
12555 bit length of glyphless.ch to 25 (Bug#11082).
12557 2012-03-26 Chong Yidong <cyd@gnu.org>
12559 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12560 (command_loop_1): Use it; inhibit selection update for
12561 handle-select-window too (Bug#8996).
12563 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12565 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12567 2012-03-25 Kenichi Handa <handa@m17n.org>
12569 * dispextern.h (struct glyph): Change the bit length of
12570 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12572 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12574 * s/ms-w32.h (tzname): Include time.h before redirecting to
12575 _tzname. Fixes the MSVC build. (Bug#9960)
12577 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12579 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12582 * xterm.c (XTread_socket): Only modify handling_signal if
12583 !SYNC_INPUT. (Bug#11080)
12585 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12587 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12588 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12589 when fetching a multibyte character consumes more bytes than
12590 CHAR_BYTES returns, due to unification of CJK characters in
12591 string_char. (Bug#11073)
12593 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12595 * process.c (wait_reading_process_output): Handle pty disconnect
12596 by refraining from sending oneself a SIGCHLD (bug#10933).

12603 Mark string as coming from a prefix property.
12604 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12605 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12607 2012-03-21 Chong Yidong <cyd@gnu.org>
12609 * xfaces.c (Vface_remapping_alist): Doc fix.
12611 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12613 * w32proc.c (Fw32_set_console_codepage)
12614 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

12619 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12620 to reflect default non-nil value of redisplay-dont-pause.
12622 2012-03-19 Kenichi Handa <handa@m17n.org>
12624 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12625 it fit in a valid range (Bug#11003).
12627 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12629 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12630 that is not from display property, accept the row as a "cursor
12631 row" if one of the string's character has a non-nil `cursor'
12632 property. Fixes cursor positioning when there are newlines in
12633 overlay strings, e.g. in icomplete.el. (Bug#11035)
12635 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12637 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12639 2012-03-12 Chong Yidong <cyd@gnu.org>
12641 * eval.c (inhibit_lisp_code): Rename from
12642 inhibit_window_configuration_change_hook; move from window.c.
12644 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12645 * window.c (run_window_configuration_change_hook)
12646 (syms_of_window): Callers changed.

12665 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12666 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12669 2012-03-03 Glenn Morris <rgm@gnu.org>
12671 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12673 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12675 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12676 position past the first glyph_row that ends at ZV. (Bug#10902)
12677 (redisplay_window, next_element_from_string): Fix typos in
12679 (redisplay_window): Pass to move_it_vertically the margin in
12680 pixels, not in screen lines.
12682 2012-03-02 Glenn Morris <rgm@gnu.org>
12684 * buffer.c (buffer-list-update-hook): Doc fix.
12686 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12688 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12689 push_it before setting up the iterator for the first overlay
12690 string, even if we have an empty string loaded.
12691 (next_overlay_string): If there's an empty string on the iterator
12692 stack, pop the stack. (Bug#10903)
12694 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12696 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12697 Suggested by Stefan Monnier in
12698 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12699 * alloc.c (widen_to_Lisp_Object): New static function.
12700 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12701 and widening them to Lisp_Objects. This would work even if
12702 USE_LSB_TAG is defined and wide integers are used, which might
12703 happen in a future version of Emacs.
12705 2012-02-25 Chong Yidong <cyd@gnu.org>
12707 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12710 * xselect.c (Fx_selection_exists_p): Doc fix.
12711 (x_clipboard_manager_save_all): Print an informative message
12712 before saving to clipboard manager.
12714 2012-02-24 Chong Yidong <cyd@gnu.org>
12716 * keyboard.c (process_special_events): Handle all X selection
12717 requests in kbd_buffer, not just the next one (Bug#8869).
12719 2012-02-23 Chong Yidong <cyd@gnu.org>
12721 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12722 call when setting menu-bar-lines and tool-bar-lines parameters.
12723 (unwind_create_frame_1): New helper function.
12725 * window.c (inhibit_window_configuration_change_hook): New var.

12744 when computing $valmask.
12746 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12747 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12748 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12749 It's useless in that case, and it can cause problems on hosts
12750 that allocate halves of EMACS_INT values separately.
12751 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12752 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12753 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12754 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12755 it avoids undefined behavior on hosts where shifting right by more
12756 than the word width has undefined behavior.
12758 2012-02-19 Chong Yidong <cyd@gnu.org>
12760 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12761 (Funhandled_file_name_directory, Ffile_name_as_directory)
12762 (Fdirectory_file_name, Fexpand_file_name)
12763 (Fsubstitute_in_file_name): Protect against invalid file handler
12764 return values (Bug#10845).
12766 2012-02-18 Eli Zaretskii <eliz@gnu.org>

12775 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
12777 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
12778 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12780 2012-02-15 Chong Yidong <cyd@gnu.org>
12782 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12783 marked as special. Also, starting docstrings with * is obsolete.

12798 2012-02-12 Chong Yidong <cyd@gnu.org>
12800 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12801 as that creates a dangerous corner case.
12803 * window.c (Fdelete_window_internal): Invalidate the mouse
12804 highlight (Bug#9904).
12806 2012-02-12 Glenn Morris <rgm@gnu.org>
12808 * xselect.c (Fx_own_selection_internal)
12809 (Fx_get_selection_internal, Fx_disown_selection_internal)
12810 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12811 * nsselect.m (Fx_own_selection_internal)
12812 (Fx_disown_selection_internal, Fx_selection_exists_p)
12813 (Fx_selection_owner_p, Fx_get_selection_internal):
12814 Sync docs and argument specs with the xselect.c versions.
12816 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12818 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
12820 2012-02-11 Eli Zaretskii <eliz@gnu.org>
12822 * w32select.c (Fx_selection_exists_p): Sync doc string and
12823 argument list with xselect.c. (Bug#10783)
12825 * w16select.c (Fx_selection_exists_p): Sync doc string and
12826 argument list with xselect.c. (Bug#10783)

12836 2012-02-07 Chong Yidong <cyd@gnu.org>
12838 * buffer.c (Fbuffer_local_variables)
12839 (buffer_lisp_local_variables): Handle unbound vars correctly;
12840 don't let Qunbound leak into Lisp.
12842 2012-02-07 Glenn Morris <rgm@gnu.org>
12844 * image.c (Fimagemagick_types): Doc fix.
12846 * image.c (imagemagick-render-type): Change it from a lisp object
12847 to an integer. Move the doc here from the lisp manual.
12848 Treat all values not equal to 0 the same.
12850 2012-02-06 Chong Yidong <cyd@gnu.org>
12852 * doc.c (store_function_docstring): Avoid applying docstring of
12853 alias to base function (Bug#2603).

13354 (Fword_search_backward, Fword_search_forward)
13355 (Fword_search_backward_lax, Fword_search_forward_lax):
13356 Use `Fword_search_regexp' instead of `wordify'. Doc fix.
13357 (syms_of_search): Define `Sword_search_regexp'. (Bug#10145)
13359 2011-12-01 Stefan Monnier <monnier@iro.umontreal.ca>
13361 * fileio.c (Finsert_file_contents): Move after-change-function call
13362 to before the "handled:" label, since all "goto handled" appear in
13363 cases where the *-change-functions have already been properly called
13366 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
13368 * keyboard.c (interrupt_signal): Don't call kill-emacs when
13369 waiting for input. (Bug#10169)
13371 2011-11-30 Eli Zaretskii <eliz@gnu.org>
13373 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13374 verifies glyph row's hash code--we have just reallocated the
13375 glyphs, so their contents can be complete garbage. (Bug#10164)
13377 2011-11-30 Juanma Barranquero <lekktu@gmail.com>
13379 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Add missing check.

13408 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
13409 of scroll runs so as to avoid assigning disabled bogus rows and
13410 unnecessary graphics copy operations.
13412 2011-11-27 Eli Zaretskii <eliz@gnu.org>
13414 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

13421 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13422 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13423 this macro definition.
13425 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
13428 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

13441 Rename locals to avoid shadowing.
13442 * fileio.c (Finsert_file_contents):
13443 Rename inner 'gcpro1' to 'inner_gcpro1' to avoid shadowing.
13444 * process.c (wait_reading_process_output):
13445 Rename inner 'proc' to 'p' to avoid shadowing.
13446 Indent for consistency with usual Emacs style.
13448 2011-11-25 Eli Zaretskii <eliz@gnu.org>
13450 * xdisp.c (redisplay_window): If cursor row is not fully visible
13451 after recentering, and scroll-conservatively is set to a large
13452 number, scroll window by a few more lines to make the cursor fully
13453 visible and out of scroll-margin. (Bug#10105)
13454 (start_display): Don't move to the next line if the display should
13455 start at a newline that is part of a display vector or an overlay
13456 string. (Bug#10119)
13458 2011-11-24 Juri Linkov <juri@jurta.org>

13481 2011-11-22 Eli Zaretskii <eliz@gnu.org>
13483 * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-
13484 and header-lines, as they don't have one computed for them.
13487 * .gdbinit (prow): Make displayed values more self-explaining.
13488 Add row's hash code.
13490 2011-11-21 Lars Magne Ingebrigtsen <larsi@gnus.org>

13533 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
13535 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13536 Otherwise, valgrind does not work on some platforms.
13537 Problem reported by Andreas Schwab in
13538 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13539 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13540 is set, removing the need for VIRT_ADDRESS_VARIES.
13541 (PURE_P): Use a more-efficient implementation that needs just one
13542 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13543 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13544 to 4 (xorl, subq, cmpq, setbe).
13545 * alloc.c (pure): Always extern now, since that's the
13546 VIRT_ADDR_VARIES behavior.
13547 (PURE_POINTER_P): Use a single comparison, not two, for
13548 consistency with the new puresize.h.
13549 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13550 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
13551 Remove VIRT_ADDR_VARIES no longer needed.
13553 2011-11-19 Eli Zaretskii <eliz@gnu.org>
13555 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
13556 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13557 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13558 behave as if the cursor position were at the window margin.
13560 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13561 and the cursor position is out of bounds, behave as if the cursor
13562 position were at the window margin. (Bug#10075)
13564 2011-11-18 Chong Yidong <cyd@gnu.org>
13566 * window.c (Fwindow_combination_limit): Make first argument
13567 non-optional, since it is meaningless for live windows like the

13581 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
13582 hash values of the two rows.
13583 (copy_row_except_pointers): Preserve the used[] arrays and the
13584 hash values of the two rows. (Bug#10035)
13585 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13587 * xdisp.c (row_hash): New function, body extracted from
13588 compute_line_metrics.
13589 (compute_line_metrics): Call row_hash, instead of computing the
13592 * dispnew.c (verify_row_hash): Call row_hash for computing the
13593 hash code of a row, instead of duplicating code from xdisp.c.
13595 * dispextern.h (row_hash): Add prototype.
13597 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13599 * frame.c (delete_frame): Don't delete the terminal when the last
13600 X frame is closed if emacs is built with GTK toolkit.

13621 * window.c (Fwindow_nest): Rename to Fwindow_combination_limit.
13622 (Fset_window_nest): Rename to Fset_window_combination_limit.
13623 (Vwindow_nest): Rename to Vwindow_combination_limit.
13624 (recombine_windows, make_parent_window, make_window)
13625 (Fsplit_window_internal, saved_window)
13626 (Fset_window_configuration, save_window_save): Rename all
13627 occurrences of window_nest to window_combination_limit.
13629 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
13631 * image.c (imagemagick_load_image): Fix typo.
13633 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13635 * xdisp.c (display_line): Move the call to
13636 highlight_trailing_whitespace before the call to
13637 compute_line_metrics, since the latter needs to see the final
13638 faces of all the glyphs to compute ROW's hash value.
13639 Fixes assertion violations in row_equal_p. (Bug#10035)
13641 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13643 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13644 just return (bug#10044).
13646 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13648 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13649 with user-defined heap size. Bump the default size of the temacs
13650 heap to 27MB, to avoid memory warning when running temacs.
13651 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13653 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13654 current_matrix and desired_matrix. (Bug#9990)
13655 (verify_row_hash) [XASSERTS]: New function.
13656 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
13657 that the hash value of glyph rows is correct.

13673 * nsfns.m (unwind_create_frame):
13674 * w32fns.c (unwind_create_frame): Use Fmemq to check if frame is in
13675 Vframe_list (Bug#9999).

13686 2011-11-11 Johan Bockgård <bojohan@gnu.org>
13688 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
13689 avoid a crash (bug#9496).
13691 2011-11-09 Chong Yidong <cyd@gnu.org>
13693 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

13700 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13702 Avoid some portability problems by eschewing 'extern inline' functions.
13703 The trivial performance wins aren't worth the portability hassles; see
13704 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13706 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13707 (window_box_width, window_box_left, window_box_left_offset)
13708 (window_box_right, window_box_right_offset): Undo previous change,
13709 by removing the "extern"s.
13710 * intervals.c (adjust_intervals_for_insertion)
13711 (adjust_intervals_for_deletion): Undo previous change,
13712 making these static again.
13713 (offset_intervals, temp_set_point_both, temp_set_point)
13714 (copy_intervals_to_string): No longer inline.
13715 * xdisp.c (window_text_bottom_y, window_box_width)

13743 * window.c (Fwindow_nest, Fset_window_nest)
13744 (Fset_window_new_total, Fset_window_new_normal)
13745 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
13746 (delete_all_subwindows): Rename to delete_all_child_windows.
13747 (Fdelete_other_windows_internal, Fset_window_configuration):
13748 Call delete_all_child_windows instead of delete_all_subwindows.
13749 * frame.c (delete_frame): Call delete_all_child_windows instead
13750 of delete_all_subwindows.
13752 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
13754 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
13755 This is also needed for porting to any host where GC_MARK_STACK is
13756 not GC_MAKE_GCPROS_NOOPS.
13757 (which_symbols): Use it.
13759 2011-11-07 Kenichi Handa <handa@m17n.org>
13761 * coding.c (coding_set_destination): Check coding->src_pos only
13762 when coding->src_object is a buffer (bug#9910).

13768 process_coding to 0 (bug#9912).
13770 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13772 * xmenu.c (cleanup_widget_value_tree): New function.
13773 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13774 calling free_menubar_widget_value_tree directly (Bug#9830).
13776 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
13778 Fix some portability problems with 'inline'.
13779 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13780 (window_box_width, window_box_left, window_box_left_offset)
13781 (window_box_right, window_box_right_offset): Declare extern.
13782 Otherwise, these inline functions do not conform to C99 and
13783 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13784 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13785 * intervals.c (adjust_intervals_for_insertion)
13786 (adjust_intervals_for_deletion): Now extern, because otherwise the
13787 extern inline functions 'offset_intervals' couldn't refer to it.
13788 (static_offset_intervals): Remove.
13789 (offset_intervals): Rewrite using the old contents of
13790 static_offset_intervals. The old version didn't conform to C99
13791 because an extern inline function contained a reference to an
13792 identifier with static linkage.
13794 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
13796 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14096 (bidi_resolve_weak): Don't enter the expensive loop if the current
14097 position is before next_en_pos. Record the bidi type of the first
14098 non-ET, non-BN character we find, in addition to its position.
14099 (bidi_level_of_next_char): Invalidate next_en_type when
14100 next_en_pos is over-stepped.
14102 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14104 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14105 * editfns.c: Rewrite current-time-zone so that it invokes
14106 the equivalent of (format-time-string "%Z") to get the time zone name.
14107 This fixes a bug when the time zone name contains characters that
14108 need converting from the system time locale to Emacs internal format.
14109 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14110 that patch fixed format-time-string to do the conversion, but
14111 I forgot to fix current-time-zone.
14112 (format_time_string): New function, containing most of
14113 what Fformat_time_string used to contain.
14114 (Fformat_time_string): Rewrite in terms of format_time_string.
14115 This doesn't change this function's behavior.
14116 (current-time-zone): Rewrite to use format_time_string.
14117 This fixes the bug reported by Michael Schierl in
14118 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14119 Jason Rumney's 2007-06-07 change worked around this bug, but
14121 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14123 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14125 * xdisp.c (start_display): If the character at POS is displayed
14126 via a display vector, reset IT->current.dpvec_index to zero.
14127 (try_window_reusing_current_matrix): If a line ends in a display
14128 vector or the next line starts in a display vector, continue
14129 redrawing the window even though the character position of
14130 start_row was reached.
14133 2011-10-18 Chong Yidong <cyd@gnu.org>
14135 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14136 with nobreak-char-display too.
14138 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14140 Fix part 3 of bug#9771.
14141 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14142 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14143 non-neutral characters if the current character is a paragraph
14144 separator (a.k.a. Newline). This avoids running the same
14145 expensive loop twice, once when we consume the preceding newline
14146 and the other time when the line actually needs to be displayed.
14147 Avoid the loop when we see neutrals on the base embedding level
14148 following a character whose directionality is the same as the
14149 paragraph's. This avoids running the expensive loop when a line
14150 ends in a long sequence of neutrals, like control characters.
14151 Add assertion against STRONG_AL type. Slightly rearrange code
14152 that determines the type of a neutral given the first non-neutral
14154 (bidi_level_of_next_char): Set next_en_pos to zero when
14155 invalidating its info.
14157 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14159 * xdisp.c (push_display_prop): Determine whether to record string
14160 or buffer position by IT->string, not by IT->method. Allow
14161 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14162 (move_it_vertically_backward): Don't look for character position
14163 immediately after the newline when in a continuation line.
14166 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14168 * window.c (coordinates_in_window): Rewrite and delabelize
14169 vertical border check. (Bug#5357) (Bug#9618)

14179 avoid crash when xmalloc overrun checking is enabled.
14181 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14183 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14184 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14185 cursor motion with <left> and <right> arrow keys.
14187 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14188 some callers set that themselves.
14190 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14192 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14193 display string and the previous row comes from the same string and
14194 is empty. (Bug#9739) (Bug#9738)
14196 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14198 * doc.c (get_doc_string): Encode file name (bug#9735).

14202 * bidi.c (bidi_level_of_next_char):
14203 * xdisp.c (get_visually_first_element): Remove old incorrect
14204 comments regarding the Unicode Line Separator character.
14206 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.

14217 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14219 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14220 Some packages use them to denote characters with modifiers.
14222 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14224 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14225 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14226 matching a pp-number. Rename parameter var to var1.

14254 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14255 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14256 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14257 this makes Emacs dump core during garbage collection on rare
14258 occasions. sizeof is obviously inferior to offsetof here, so
14259 stick with offsetof.
14260 (GC_POINTER_ALIGNMENT): New macro.
14261 (mark_memory): Omit 3rd (offset) arg; caller changed.
14262 Don't assume EMACS_INT alignment is the same as pointer alignment.
14264 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14266 * keyboard.c (read_key_sequence_remapped): New var.
14267 (read_key_sequence): Compute remapping in the right buffer.
14268 (command_loop_1): Use read_key_sequence's remapping directly.
14270 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14272 * dired.c (file_name_completion): Don't expand file name.
14273 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14274 before checking file name handler.
14276 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14277 they've been requested explicitly (bug#9591).
14279 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14281 * keymap.c (Fsingle_key_description): Use make_specified_string
14282 instead of build_string to build string from push_key_description.
14285 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14287 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14288 This fixes a Y2038 bug on 64-bit hosts.
14289 * buffer.c (reset_buffer):
14290 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14291 (Fclear_buffer_auto_save_failure):
14292 Use 0, not -1, to represent an unset failure time, since time_t
14293 might not be signed.
14295 Remove dependency on glibc malloc internals.
14296 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14297 Move back here from lisp.h, but with their new implementations.
14298 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14299 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14300 * charset.c (charset_table_init): New static var.
14301 (syms_of_charset): Use it instead of xmalloc. This removes a
14302 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14303 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14304 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14305 Move back to alloc.c.
14306 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14307 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14309 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14311 * nsterm.m (windowDidResize): Call x_set_window_size only when
14312 ns_in_resize is true. Otherwise set pixelwidth/height and
14313 call change_frame_size (Bug#9628).
14315 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14317 Port --enable-checking=all to Fedora 14 x86-64.
14318 * charset.c (syms_of_charset): Also account for glibc malloc's
14319 internal overhead when calculating the initial malloc maximum.
14321 Port --enable-checking=all to Fedora 14 x86.
14322 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14324 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14325 (overrun_check_realloc, overrun_check_free):
14326 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14327 That way, xmalloc returns a properly-aligned pointer even if
14328 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14329 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14330 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14331 into account when calculating the initial malloc maximum.
14332 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14333 Move here from alloc.c, so that charset.c can use it too.
14334 Properly align; the old code wasn't right for common 32-bit hosts
14335 when configured with --enable-checking=all.
14336 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14337 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14339 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14341 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14344 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14346 * xdisp.c (compute_display_string_end): If there's no display
14347 string at CHARPOS, return -1.
14349 * bidi.c (bidi_fetch_char): When compute_display_string_end
14350 returns a negative value, treat the character as a normal
14351 character not covered by a display string. (Bug#9624)
14353 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14355 * lread.c (Fread_from_string): Fix typo in docstring.
14357 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14359 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14360 newline, reseat the iterator instead of bidi-iterating there one
14361 character at a time. (Bug#9610)
14362 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14363 TO_CHARPOS if the bidi iterator is at base embedding level.
14365 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14367 * lread.c (readevalloop): Use correct code for NBSP.
14368 (read1): Likewise. (Bug#9608)
14370 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14372 * dbusbind.c (Fdbus_register_signal): When service is not
14373 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14375 2011-09-25 Glenn Morris <rgm@gnu.org>
14377 * buffer.c (truncate-lines): Doc fix.
14379 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14381 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14382 (Fset_window_next_buffers): Doc fix.
14384 2011-09-24 Glenn Morris <rgm@gnu.org>
14386 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14388 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14390 Fix minor problems found by static checking.
14391 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14392 * indent.c (Fvertical_motion): Fix == vs = typo.
14394 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14396 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14397 Default value is now t. Doc fix.
14399 * indent.c (Fvertical_motion): Compute and apply the overshoot
14400 logic when moving up, not only when moving down. Fix the
14401 confusing name and values of the it_overshoot_expected variable;
14402 logic changes accordingly. (Bug#9254) (Bug#9549)
14404 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14405 CHARPOS is covered by a display string which includes newlines.
14406 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14407 is covered by a display string with embedded newlines.
14409 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14411 * dbusbind.c (Fdbus_register_signal): Add match rule to
14412 Vdbus_registered_objects_table. (Bug#9581)
14413 (Fdbus_register_method, Vdbus_registered_objects_table):
14416 2011-09-24 Jim Meyering <meyering@redhat.com>
14418 do not ignore write error for any output size
14419 The previous change was incomplete.
14420 While it makes emacs --batch detect the vast majority of stdout
14421 write failures, errors were still ignored whenever the output size is
14422 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14423 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14424 && echo FAIL: ignored write error
14425 FAIL: ignored write error
14426 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14427 && echo FAIL: ignored write error
14428 FAIL: ignored write error
14429 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14431 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14433 * emacs.c (Fkill_emacs): In noninteractive mode exit
14434 non-successfully if a write error occurred on stdout. (Bug#9574)
14436 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14438 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14441 * dispextern.h (struct it): Update the comment documenting what
14444 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14446 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14447 a display string, extend search for cursor position to end of row.
14448 (find_row_edges): If the row ends in a newline from a display
14449 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14450 Handle the case of a display string with multiple newlines.
14451 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14452 non-empty line. Fixes confusing cursor motion with arrow keys at
14453 the beginning of a line that starts with whitespace.
14455 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14457 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14460 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14462 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14463 boolean (Bug#9154).
14465 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14467 * xdisp.c (display_line): Record maximum and minimum buffer
14468 positions even if no glyphs were produced (e.g., by a zero-width
14469 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14470 buffer positions that will be removed from the glyph row because
14472 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14473 column is beyond frame width: don't subtract 1 "pixel" when
14474 computing width of the stretch.
14475 (reseat_at_next_visible_line_start): Undo the change made on
14476 2011-09-17 that saved paragraph information and restored it after
14477 the call to `reseat'. (Bug#9545)
14479 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14481 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14482 and turn window cursor on if cleared (Bug#9415).
14484 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14486 * search.c (boyer_moore): Take unibyte characters from pattern
14487 literally. (Bug#9458)
14489 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14491 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14493 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14495 Fix minor problem found by static checking.
14496 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14497 initialized, to pacify gcc -Wuninitialized.
14499 * fileio.c: Report proper errno when syscall falls.
14500 (Finsert_file_contents): Save and restore errno,
14501 so that report_file_error outputs the correct diagnostic.
14502 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14504 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14506 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14508 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14510 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14511 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14513 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14515 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14516 about the current paragraph and restore it after the call to reseat.
14518 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14519 (bidi_find_paragraph_start): Search back for paragraph beginning
14520 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14521 (bidi_move_to_visually_next): Only trigger paragraph-related
14522 computations when the last character is a newline or at EOB, not
14523 just any NEUTRAL_B. (Bug#9470)
14525 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14526 truncated lines if point is covered by a display string. (Bug#9524)
14528 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14530 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14531 (cons_to_x_long): New function.
14532 (lisp_data_to_selection_data): Use it. Correct the test for
14533 short-versus-long data; it was negated. Break out of vector
14534 loop, for efficiency, when a long datum is discovered.
14536 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14538 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14540 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14542 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14543 GCC PR/17406) by declaring this function with external scope.
14545 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14547 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14548 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14550 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14552 * editfns.c (Fformat): Correctly handle text properties on "%%".
14554 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14556 * xterm.c (x_draw_composite_glyph_string_foreground):
14557 * w32term.c (x_draw_composite_glyph_string_foreground):
14558 * term.c (encode_terminal_code):
14559 * composite.c (composition_update_it, get_composition_id):
14560 * xdisp.c (get_next_display_element)
14561 (fill_composite_glyph_string): Add comments about special meaning
14562 of TAB characters in a composition.
14564 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14566 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14567 This occurs when processing a multibyte format.
14568 Problem reported by Wolfgang Jenker.
14570 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14572 * xdisp.c (try_cursor_movement): Only check for exact match if
14573 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14575 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14577 Remove unused external symbols.
14578 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14579 * xdisp.c (calc_pixel_width_or_height): Now static.
14580 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14581 * indent.c (check_display_width):
14582 * w32term.c: Fix comment to match code.
14583 * xterm.c, xterm.h (x_catching_errors): Remove.
14585 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14587 * xselect.c: Use signed conversions more consistently (Bug#9498).
14588 (selection_data_to_lisp_data): Assume incoming selection data are
14589 signed integers, not unsigned. This is to be consistent with
14590 outgoing selection data, which was modified to use signed integers
14591 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14592 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14593 expects long, not unsigned long.
14595 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14597 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14598 computation of loop end. Reported by Johan Bockgård
14601 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14603 * frame.c (Fother_visible_frames_p): Function deleted.
14605 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14607 * indent.c (compute_motion): Process display vector front to back
14608 rather than the other way around. (Bug#2496)
14610 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14612 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14614 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14616 * minibuf.c (Fread_from_minibuffer): Doc fix.
14618 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14620 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14621 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14623 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14625 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14626 value for non-existent files.
14628 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14630 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14631 set its "size" to -1. This will set the modtime_size field of
14632 the corresponding buffer to -1, which is what
14633 verify-visited-file-modtime expects for files that do not exist.
14636 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14638 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14640 * lisp.h: ... from here. push_key_description is no longer
14641 defined in keyboard.c, so its declaration should not be in
14642 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14643 logically belongs with push_key_description.
14645 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14647 * buffer.h: Include <sys/types.h> instead of <time.h>.
14648 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14649 Problem reported by Herbert J. Skuhra.
14651 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14653 * xml.c (parse_region): Make the parsing work for
14654 non-comment-starting XML files again (bug#9144).
14656 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14658 * image.c (gif_load): Fix calculation of bottom and right corner.
14661 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14663 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14664 redisplay in small windows.
14666 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14668 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14670 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14672 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14673 Operate on live windows only.
14675 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14677 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14679 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14681 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14682 only under bidi iteration.
14684 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14686 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14688 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14690 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14691 Without this fix, the command to link temacs failed due to an
14692 undefined symbol __builtin_isnan. This is because
14693 /usr/include/iso/math_c99.h #defines isnan(x) to
14694 __builtin_isnan(x), but the bundled gcc, which identifies itself
14695 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14697 * floatfns.c (isnan): #undef, and then #define to a clone of
14699 (Fisnan): Always define, since it's always available now.
14700 (syms_of_floatfns): Always define isnan at the Lisp level.
14702 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14704 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14706 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14708 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14709 The previous code assumed that file offsets (off_t values) fit in
14710 EMACS_INT variables, which is not true on typical 32-bit hosts.
14711 The code messed up by falsely reporting buffer overflow in cases
14712 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14713 when "big" contains more than 2**29 bytes, even though this
14714 inserts just one byte and does not overflow the buffer.
14715 (Finsert_file_contents): Store file offsets as off_t
14716 values, not as EMACS_INT values. Check for overflow when
14717 converting between EMACS_INT and off_t. When checking for
14718 buffer overflow or for overlap, take the offsets into account.
14719 Don't use EMACS_INT for small values where int suffices.
14720 When checking for overlap, fix a typo: ZV was used where
14721 ZV_BYTE was intended.
14722 (Fwrite_region): Don't assume off_t fits into 'long'.
14723 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14725 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14727 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14729 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14731 sprintf-related integer and memory overflow issues (Bug#9412).
14733 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14734 (esprintf, exprintf, evxprintf): New functions.
14735 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14736 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14737 (modify_event_symbol): Do not assume that the length of
14738 name_alist_or_stem is safe to alloca and fits in int.
14739 (Fexecute_extended_command): Likewise for function name and binding.
14740 (Frecursion_depth): Wrap around reliably on integer overflow.
14741 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14742 since some callers pass EMACS_INT values.
14743 (Fsingle_key_description): Don't crash if symbol name contains more
14744 than MAX_ALLOCA bytes.
14745 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14746 (get_minibuffer): Arg is now EMACS_INT, not int.
14747 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14748 (esprintf, exprintf, evxprintf): New decls.
14749 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14751 * dbusbind.c (signature_cat): New function.
14752 (xd_signature, Fdbus_register_signal):
14753 Do not overrun buffer; instead, report string overflow.
14755 * dispnew.c (add_window_display_history): Don't overrun buffer.
14756 Truncate instead; this is OK since it's just a log.
14758 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14759 even if the time zone offset is outlandishly large.
14760 Don't mishandle offset == INT_MIN.
14762 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14763 when creating daemon; the previous buffer-overflow check was incorrect.
14765 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14766 which has the guts of the old verror function.
14768 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14769 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14771 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14772 (font_unparse_xlfd): Don't blindly alloca long strings.
14773 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14774 fits in int, when using sprintf. Use single snprintf to count
14775 length of string rather than counting it via multiple sprintfs;
14776 that's simpler and more reliable.
14777 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14778 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14779 sprintf, in case result does not fit in int.
14781 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14782 (fontset_from_font): Print it.
14784 * frame.c (tty_frame_count): Now printmax_t, not int.
14785 (make_terminal_frame, set_term_frame_name): Print it.
14786 (x_report_frame_params): In X, window IDs are unsigned long,
14787 not signed long, so print them as unsigned.
14788 (validate_x_resource_name): Check for implausibly long names,
14789 and don't assume name length fits in 'int'.
14790 (x_get_resource_string): Don't blindly alloca invocation name;
14791 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14794 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14795 (xg_check_special_colors, xg_set_geometry):
14796 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14798 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14799 Use esprintf, not sprintf, in case result does not fit in int.
14801 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14802 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14803 it as a large positive number.
14804 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14805 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14807 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14808 in case result does not fit in int.
14810 * print.c (float_to_string): Detect width overflow more reliably.
14811 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14812 buffer overrun. Don't assume list length fits in 'int'. Treat
14813 print length of 0 as 0, not as infinity; to be consistent with other
14814 uses of print length in this function. Don't overflow print length
14815 index. Don't assume hash table size fits in 'long', or that
14816 vectorlike size fits in 'unsigned long'.
14818 * process.c (make_process): Use printmax_t, not int, to format
14819 process-name gensyms.
14821 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14823 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14824 to avoid potential buffer overrun.
14826 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14827 if X resource line is longer than 512 bytes.
14829 * xfns.c (x_window): Make sprintf buffer a bit bigger
14830 to avoid potential buffer overrun.
14832 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14834 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14836 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14838 Integer overflow fixes for scrolling, etc.
14839 Without these, Emacs silently mishandles large integers sometimes.
14840 For example, "C-u 4294967297 M-x recenter" was treated as if
14841 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14843 * xdisp.c (try_window_id): Check Emacs fixnum range before
14844 converting to 'int'.
14846 * window.c (window_scroll_line_based, Frecenter):
14847 Check that an Emacs fixnum is in range before assigning it to 'int'.
14848 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14849 values converted from Emacs fixnums.
14850 (Frecenter): Don't wrap around a line count if it is out of 'int'
14851 range; instead, treat it as an extreme value.
14852 (Fset_window_configuration, compare_window_configurations):
14853 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14855 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14856 that can exceed INT_MAX. Check that EMACS_INT value is in range
14857 before assigning it to the (possibly-narrower) index.
14858 (match_limit): Don't assume that a fixnum can fit in 'int'.
14860 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14863 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14864 (Fvertical_motion): Don't wrap around LINES values that don't fit
14865 in 'int'. Instead, treat them as extreme values. This is good
14866 enough for windows, which can't have more than INT_MAX lines anyway.
14868 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14870 * Require libxml/parser.h to avoid compilation warning.
14872 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14874 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14875 since this reportedly can destroy thread storage.
14877 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14879 * syntax.c (find_defun_start): Update all cache variables if
14880 exiting early (Bug#9401).
14882 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14884 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14886 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14887 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14888 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14890 * term.c (tty_append_glyph): New function.
14891 (produce_stretch_glyph): Static function and its prototype deleted.
14893 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14896 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14898 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14899 when checking :margin (Bug#9390).
14900 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14901 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14902 so that the name doesn't mislead. All uses changed.
14904 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14906 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14909 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14911 * xdisp.c (move_it_to): Don't bail out early when reaching
14912 position beyond to_charpos, if we are scanning backwards.
14913 (move_it_vertically_backward): When DY == 0, make sure we get to
14914 the first character in the line after the newline.
14916 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14918 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14919 (ccl_driver): Do not generate an out-of-range pointer.
14920 (Fccl_execute_on_string): Remove unnecessary check for
14921 integer overflow, noted by Stefan Monnier in
14922 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14923 Remove a FIXME that didn't need fixing.
14924 Simplify the newly-introduced buffer reallocation code.
14926 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14928 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14930 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14932 Integer and memory overflow issues (Bug#9196).
14934 * doc.c (get_doc_string): Rework so that
14935 get_doc_string_buffer_size is the actual buffer size, rather than
14936 being 1 less than the actual buffer size; this makes xpalloc more
14939 * image.c (x_allocate_bitmap_record, cache_image):
14940 * xselect.c (Fx_register_dnd_atom):
14941 Simplify previous changes by using xpalloc.
14943 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14944 since either will do and ptrdiff_t is convenient with xpalloc.
14946 * charset.c (charset_table_size)
14947 (struct charset_sort_data.priority): Now ptrdiff_t.
14948 (charset_compare): Don't overflow if priorities differ greatly.
14949 (Fsort_charsets): Don't assume list length fits in int.
14950 Check for size-calculation overflow when allocating sort data.
14951 (syms_of_charset): Allocate an initial charset table that is
14952 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14954 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14956 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14957 The actual value is always <= INT_MAX, and leaving it unsigned made
14958 overflow checking harder.
14960 * dispextern.h (struct glyph_matrix.rows_allocated)
14961 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14962 with xpalloc. The values are still always <= INT_MAX.
14964 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14966 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14967 (SAFE_NALLOCA): New macro.
14969 * region-cache.c (struct boundary.pos, find_cache_boundary)
14970 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14971 (set_cache_region, invalidate_region_cache)
14972 (revalidate_region_cache, know_region_cache, region_cache_forward)
14973 (region_cache_backward, pp_cache):
14974 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14975 so that ptrdiff_t * can be passed to xpalloc.
14976 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14977 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14978 (pp_cache): Don't assume cache_len fits in int.
14979 * region-cache.h: Adjust extern decls to match.
14981 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14982 EMACS_INT, since either will do, for xpalloc.
14984 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14985 (xnmalloc, xnrealloc, xpalloc): New functions.
14987 * bidi.c (bidi_shelve_header_size): New constant.
14988 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14989 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14991 * bidi.c (bidi_cache_shrink):
14992 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14994 Don't update size of array until after memory allocation succeeds,
14995 because xmalloc/xrealloc may not return.
14996 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14997 now that we have proper integer overflow checking.
14998 (record_overlay_string, overlay_strings): Catch overflows when
14999 calculating size of overlay_str_buf.
15001 * callproc.c (Fcall_process): Check for size overflow when
15002 calculating size of args2.
15003 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15004 Normally we prefer signed values, but sticking with ptrdiff_t would
15005 require adding more-complicated checks.
15007 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15008 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15009 Redo buffer-overflow calculations to avoid integer overflow.
15010 Add a FIXME comment where memory seems to be over-allocated.
15012 * character.c (Fstring): Check for size-calculation overflow.
15014 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15015 unnecessary integer overflow. Check for size overflow.
15016 (encode_coding_object): Don't update size until xmalloc succeeds.
15018 * composite.c (get_composition_id): Check for overflow in glyph
15019 length calculations.
15021 Integer and memory overflow fixes for display code.
15022 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15023 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15024 (scrolling_window): Check for overflow in size calculations.
15025 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15026 Don't assume glyph table len fits in int.

15028 (row_table_size): Now ptrdiff_t, not int.
15029 (scrolling_window): Avoid overflow in size calculations.
15030 Don't update size until allocation succeeds.
15031 * fns.c (concat): Check for overflow in size calculations.
15032 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15033 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15034 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15036 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15037 (get_doc_string): Check for size calculation overflow.
15038 Don't update size until allocation succeeds.
15039 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15040 EMACS_INT, where ptrdiff_t will do.
15041 (Fsubstitute_command_keys): Check for string overflow.
15043 * editfns.c (set_time_zone_rule): Don't assume environment length
15045 (message_length): Now ptrdiff_t, not int.
15046 (Fmessage_box): Don't update size until allocation succeeds.
15047 Don't assume message length fits in int.
15048 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15050 * emacs.c (main): Do not reallocate argv, since there is a null at
15051 the end that can be overwritten, and this way there's no need to
15052 worry about size-calculation overflow.
15053 (sort_args): Check for size-calculation overflow.
15055 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15057 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15059 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15060 (x_set_scroll_bar_width, x_figure_window_size):
15061 Check for integer overflow.
15062 (x_set_alpha): Do not assume XINT fits in int.
15064 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15065 This is for the members text_lines, text_cols, total_lines, total_cols,
15066 where the system imposes an 'int' limit.
15068 * fringe.c (Fdefine_fringe_bitmap):
15069 Don't update size until alloc works.
15071 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15072 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15074 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15075 Check for size-calculation overflow.
15076 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15077 do, as we prefer signed integers.
15078 (id_to_widget.max_size, id_to_widget.used)
15079 (xg_store_widget_in_map, xg_remove_widget_from_map)
15080 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15081 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15082 Use and return ptrdiff_t, not int.
15083 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15084 * gtkutil.h: Change prototypes to match the above.
15086 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15087 are duplicate now that they've been promoted to lisp.h.
15088 (x_allocate_bitmap_record, x_alloc_image_color)
15089 (make_image_cache, cache_image, xpm_load):
15090 Don't update size until alloc is done.
15091 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15093 Check for size calculation overflow.
15094 (ct_colors_allocated_max): New constant.
15095 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

15100 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15101 Use ptrdiff_t, not int, to count maps.
15102 (read_char_minibuf_menu_prompt): Check for overflow in size
15103 calculations. Don't update size until allocation succeeds.
15104 Redo calculations to avoid overflow.
15105 * keyboard.h: Change prototypes to match the above.
15107 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15109 (current_minor_maps): Check for size calculation overflow.
15110 * keymap.h: Change prototypes to match the above.
15112 * lread.c (read1, init_obarray): Don't update size until alloc done.
15114 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15115 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.

15123 in size calculation.
15125 * region-cache.c (move_cache_gap): Check for size calculation overflow.

15133 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15134 for command line length. Do not attempt to address one before the
15135 beginning of an array, as that's not portable.
15137 * term.c (max_frame_lines): Remove; unused.
15138 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15140 (encode_terminal_code, calculate_costs): Check for size
15141 calculation overflow.
15142 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

15163 Use ptrdiff_t, not int, for sizes.
15164 (Finternal_make_lisp_face, cache_face):
15165 Check for size calculation overflow.
15166 (cache_face): Treat size calculation overflows as if they were
15167 memory exhaustion (the usual treatment), rather than aborting.
15169 * xfns.c (x_encode_text, x_set_name_internal)
15170 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15171 sizes, since they can exceed INT_MAX in size. Check for size
15172 calculation overflow.
15174 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15175 (xg_select): Check for size calculation overflow.
15176 Don't update size until alloc done.
15178 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15179 as sprintf is limited to int lengths.
15181 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15182 (X_LONG_MIN): New macros.
15183 Use them to make the following changes clearer.
15184 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15185 This change doesn't affect the value now, but it may help remind
15186 future maintainers not to raise the value too much later.
15187 (SELECTION_QUANTUM): Remove, replacing with ...
15188 (selection_quantum): ... new function, which avoids overflow.
15190 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15191 assumption that selection length fits in 'int'.
15192 (x_reply_selection_request, x_handle_selection_request)
15193 (x_get_window_property, receive_incremental_selection)
15194 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15195 (lisp_data_to_selection_data, clean_local_selection_data):

15197 (x_reply_selection_request, x_get_window_property)
15198 (receive_incremental_selection, x_property_data_to_lisp):
15199 Redo calculations to avoid overflow.
15200 (x_reply_selection_request): When sending hint, ceiling it at
15201 X_LONG_MAX rather than relying on wraparound overflow to send
15203 (x_get_window_property, receive_incremental_selection)
15204 (lisp_data_to_selection_data, x_property_data_to_lisp):
15205 Check for size-calculation overflow.

15208 Don't store size until memory allocation succeeds.
15209 (x_get_window_property): Plug memory leak on memory exhaustion.
15210 Don't double-block input; malloc is safe here. Don't assume 2**34
15211 - 4 fits in unsigned long. Add an xassert to check
15212 XGetWindowProperty overflow. Be more careful about overflow
15213 calculations, and distinguish size from memory overflow better.
15214 (receive_incremental_selection): When tracing, don't assume
15215 unsigned int is less than INT_MAX.
15216 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15217 harmful) conversions of unsigned short to int.
15218 (lisp_data_to_selection_data): Don't assume that integers
15219 in the range -65535 through -1 fit in an X unsigned short.
15220 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15221 result parameters unless successful. Rely on cons_to_unsigned
15222 to report problems with elements; the old code wasn't right anyway.
15223 (x_check_property_data): Check for int overflow; we cannot use
15224 a wider type due to X limits.
15225 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15227 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15229 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15230 (x_term_init): Check for size calculation overflow.
15231 (x_color_cells): Don't store size until memory allocation succeeds.
15232 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15233 Don't assume alloca size is less than MAX_ALLOCA.
15234 (x_term_init): Don't assume length fits in int (sprintf is limited
15237 Use ptrdiff_t for composition IDs.

15256 * image.c (xpm_get_color_table_h):
15257 * lisp.h (hash_lookup, hash_put):
15258 * minibuf.c (Ftest_completion):
15259 Use ptrdiff_t for hash table indexes, not int (which is too
15260 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15261 32-bit --with-wide-int hosts).
15263 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15264 Add a FIXME comment about memory leaks.
15265 (syms_of_charset): Don't assume xmalloc returns.

15269 * character.h (CHAR_WIDTH):
15270 * indent.c (MULTIBYTE_BYTES_WIDTH):
15271 Use sanitize_char_width to avoid undefined and/or bad behavior
15272 with outlandish widths.
15273 * character.h (sanitize_tab_width): Rename from sanitize_width,
15274 now that we have two such functions. All uses changed.
15275 (sanitize_char_width): New inline function.
15277 Don't assume that tab-width fits in int.
15278 * character.h (sanitize_width): New inline function.

15285 * fileio.c: Integer overflow issues with file modes.
15286 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15288 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15289 Remove unreachable code.
15290 (read_hex, load_charset_map_from_file): Check for integer overflow.
15292 * xterm.c: Don't go over XClientMessageEvent limit.
15293 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15294 (x_send_scroll_bar_event): Likewise. Check that the size does not
15295 exceed limits imposed by XClientMessageEvent, as well as the usual
15296 ptrdiff_t and size_t limits.
15298 * keyboard.c: Overflow, signedness and related fixes.
15299 (make_lispy_movement): Use same integer type in forward decl
15300 that is used in the definition.
15301 (read_key_sequence, keyremap_step):
15302 Change bufsize argument back to int, undoing my 2011-03-30 change.
15303 We prefer signed types, and int is wide enough here.
15304 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15305 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15306 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15307 length, not size_t. Use ptrdiff_t for index, not int.
15308 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15309 possibility of integer overflow.
15311 Overflow, signedness and related fixes for images.
15313 * dispextern.h (struct it.stack[0].u.image.image_id)
15314 (struct_it.image_id, struct image.id, struct image_cache.size)

15321 * xdisp.c (calc_pixel_width_or_height):
15322 * xfns.c (image_cache_refcount):
15323 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

15332 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15333 (lookup_image): Remove unnecessary tests.
15334 (xbm_image_p): Locals are now of int, not EMACS_INT,
15335 since parse_image_check makes sure they fit into int.
15336 (png_load, gif_load, svg_load_image):
15337 Prefer int to unsigned where either will do.
15338 (tiff_handler): New function, combining the cores of the
15339 old tiff_error_handler and tiff_warning_handler.
15340 This function is rewritten to use vsnprintf and thereby avoid
15341 stack buffer overflows. It uses only the features of vsnprintf
15342 that are common to both POSIX and native Microsoft.
15343 (tiff_error_handler, tiff_warning_handler): Use it.
15344 (tiff_load, gif_load, imagemagick_load_image):
15345 Don't assume :index value fits in 'int'.
15346 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15347 (imagemagick_load_image): Check that crop parameters fit into
15348 the integer types that MagickCropImage accepts. Don't assume
15349 Vimagemagick_render_type has a nonnegative value. Don't assume
15350 size_t fits in 'long'.
15351 (gs_load): Use printmax_t to print the widest integers possible.
15352 Check for integer overflow when computing image height and width.
15354 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15356 * xdisp.c (redisplay_window): Don't force window start if point
15357 will be invisible in the resulting window. (Bug#9324)

15361 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15362 the display spec is of the form `(space ...)'.
15363 (handle_display_spec): Return the value returned by
15364 handle_single_display_spec, not just 1 or zero.
15365 (handle_single_display_spec): If the display spec is of the form
15366 `(space ...)', and specifies display in the text area, return 2
15368 (try_cursor_movement): Check for the need to scroll more
15369 accurately, and prefer exact match for point under bidi.
15370 Don't advance `row' beyond the last row of the window.
15372 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15373 into disp_prop; all users changed.
15375 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

15387 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15388 buffers, return left-to-right.
15389 (set_cursor_from_row): Consider candidate row a win if its glyph
15390 represents a newline and point is on that newline. Fixes cursor
15391 positioning on the newline at EOL of R2L text within L2R
15392 paragraph, and vice versa.
15393 (try_cursor_movement): Check continued rows, in addition to
15394 continuation rows. Fixes unwarranted scroll when point enters a
15395 continued line of R2L text within an L2R paragraph, or vice versa.
15396 (cursor_row_p): Consider the case of point being equal to
15397 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15398 from the end of a short line to the beginning of a continued line
15399 of R2L text within L2R paragraph.
15400 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15401 composed characters.

15421 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15423 * xdisp.c (redisplay_window): When computing centering_position,
15424 account for the height of the header line. (Bug#8874)
15426 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15427 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15428 candidate is selected by the mouse, and that candidate has a
15429 composed character under the mouse.
15431 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15432 coordinates reported by pos-visible-in-window-p for a composed
15433 character in column zero.
15435 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15437 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15439 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15441 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15442 consider it a hit if to_charpos is anywhere in the range of the
15443 composed buffer positions.
15445 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15447 * image.c (gif_load): Don't assume that each subimage has the same
15448 dimensions as the base image. Handle disposal method that is
15449 "undefined" by the gif spec (Bug#9335).
15451 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15453 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15458 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15459 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15460 from an Org mode buffer to a Speedbar frame.
15462 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15463 a composition, take its buffer position from IT->cmp_it.charpos.
15464 Fixes cursor positioning at the beginning of a line that begins
15465 with a composed character.
15467 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15469 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15470 character bidirectional type, use STRONG_L instead. Fixes crashes
15471 in a buffer produced by `describe-categories'.
15473 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15474 members before the level stack, so they would be saved and
15475 restored when copying iterator state. Fixes incorrect reordering
15476 around TABs covered by display properties.
15478 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

15550 * xdisp.c (move_it_in_display_line_to): Don't invoke
15551 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15552 ppos_it. Fixes vertical cursor motion when line beginning is
15553 covered by an image. (Bug#9296)
15555 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15557 * nsterm.h (ns_run_ascript): Declare.

15562 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15563 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15564 the event loop. Get status from as_status (Bug#7276).
15566 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15567 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15568 the event loop (Bug#7276).
15570 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

15593 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15594 (Fnetwork_interface_list): Allocate in increments of bytes instead
15595 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15596 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15598 (struct ifflag_def): notrailers is smart on OSX.
15599 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15600 Get hardware address with getifaddrs if available.
15602 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15604 * xdisp.c (iterate_out_of_display_property): xassert that
15605 IT->position is set to within IT->object's boundaries. Break from
15606 the loop as soon as EOB is reached; avoids infloops in redisplay
15607 when IT->position is set up wrongly due to some bug.
15608 Set IT->current to match the bidi iterator unconditionally.
15609 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15610 entry. Force push_it to save on the stack the current
15611 buffer/string position, to be restored by pop_it. Fix flags in
15612 the iterator structure wrt the object coming from a display
15613 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15614 properties. (Bug#9284)
15616 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15618 * fontset.c (fontset_get_font_group): Add proper type checks.
15621 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15623 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
15624 and LC_VERSION_MIN_MACOSX.
15625 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
15626 (dump_it) [LC_FUNCTION_STARTS]: Use it.
15628 2011-08-08 Eli Zaretskii <eliz@gnu.org>
15630 * xdisp.c (forward_to_next_line_start): Allow to use the
15631 no-display-properties-and-no-overlays under bidi display.
15632 Set disp_pos in the bidi iterator to avoid searches for display
15633 properties and overlays.
15635 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15637 * editfns.c (Fset_time_zone_rule): Document relationship with the
15640 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
15641 the font entity extracted from the cache (Bug#8109).
15643 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15645 * composite.c (autocmp_chars): Don't reset point. That is done by
15646 restore_point_unwind (Bug#5984).
15648 2011-08-07 Juri Linkov <juri@jurta.org>
15650 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15651 to show the arg `TIME' instead of `TIMEVAL'.
15653 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15655 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15656 display property strides EOL and includes a newline, as in
15657 longlines-mode. (Bug#9254)
15658 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15659 word-wrap under bidirectional display. (Bug#9224)
15661 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15662 is non-zero, even if the data buffer is NULL. Fixes a crash in
15663 vertical-motion with longlines-mode. (Bug#9254)
15665 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15667 * bidi.c <bidi_cache_total_alloc>: Now static.
15668 (bidi_initialize): Initialize bidi_cache_total_alloc.
15670 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15673 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15674 amount allocated this far in `bidi_cache_total_alloc'.
15675 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15676 non-zero, only free the data buffer without restoring the cache
15677 contents. All callers changed.
15679 * dispextern.h (bidi_unshelve_cache): Update prototype.
15681 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15682 (move_it_in_display_line, move_it_to)
15683 (move_it_vertically_backward, move_it_by_lines): Replace the call
15684 to xfree to an equivalent call to bidi_unshelve_cache.
15685 (move_it_in_display_line_to): Fix logic of returning
15686 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15688 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15690 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15691 came from a string character with a `cursor' property. (Bug#9229)
15693 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15695 * Makefile.in (LIB_PTHREAD): New variable.
15696 (LIBES): Add LIB_PTHREAD (Bug#9216).
15698 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15699 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15701 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15703 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15705 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15707 * xterm.c (x_find_topmost_parent): New function.
15708 (x_set_frame_alpha): Find topmost parent window with
15709 x_find_topmost_parent and set the property there also (bug#9181).
15710 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15712 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15714 * callproc.c (Fcall_process): Avoid vfork clobbering
15715 the local vars buffer, coding_systems, current_dir.
15717 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15719 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15721 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15723 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15724 so that it is not optimized away.
15726 * xdisp.c (compute_display_string_pos): Remove unused local.
15728 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15730 Fix slow cursor motion and scrolling in large buffers with
15731 selective display, like Org Mode buffers. (Bug#9218)
15733 * dispextern.h (struct bidi_it): New member disp_prop_p.
15735 * xdisp.c: Remove one-slot cache of display string positions.
15736 (compute_display_string_pos): Accept an additional argument
15737 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15738 for a display string or property. If found, set DISP_PROP_P
15741 * bidi.c (bidi_fetch_char): Accept an additional argument
15742 DISP_PROP_P, and pass it to compute_display_string_pos.
15743 Only handle text covered by a display string if DISP_PROP_P is returned
15744 non-zero. All callers of bidi_fetch_char changed.
15746 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15748 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15750 2010-12-03 Don March <don@ohspite.net>
15752 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15753 last character M-[char] is translated to ESC [char] (bug#7541).
15755 2011-08-02 Kenichi Handa <handa@m17n.org>
15757 * lisp.h (uniprop_table): Extern it.
15759 * chartab.c (uniprop_table): Make it non-static.
15761 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15763 * xdisp.c (forward_to_next_line_start): Accept additional argument
15764 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15766 (reseat_at_next_visible_line_start): Use the bidi iterator state
15767 returned by forward_to_next_line_start to restore the state of
15768 it->bidi_it after backing up to previous newline. (Bug#9212)
15770 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15772 * regex.c (re_comp): Protoize.
15773 (re_exec): Fix return type.
15774 (regexec): Fix type of `ret'. (Bug#9203)
15776 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15778 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15779 This is needed if max-image-size is a floating-point number.
15781 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15783 * print.c (print_object): Print empty symbol as ##.
15785 * lread.c (read1): Read ## as empty symbol.
15787 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15789 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15790 setting frame foreground color (Bug#9175).
15791 (x_set_background_color): Likewise.
15793 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15794 contents (Bug#9176).
15795 (EmacsTooltip -init): Remove bezels and add shadows to
15798 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15799 or scroll bar (Bug#8470).
15801 * nsfont.m (nsfont_open): Remove assignment to voffset and
15802 unnecessary vars hshink, expand, hd, full_height, min_height.
15803 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15805 * nsterm.h (nsfont_info): Remove voffset field.
15807 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15809 Implement strike-through and overline on NextStep (Bug#8863).
15811 * nsfont.m (nsfont_open): Use underline position provided by font,
15812 instead of hard-coded value of 2.
15813 (nsfont_draw): Call ns_draw_text_decoration instead.
15815 * nsterm.h: Add declaration for ns_draw_text_decoration.
15817 * nsterm.m (ns_draw_text_decoration): New function for drawing
15818 underline, overline, and strike-through.
15819 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15820 ns_draw_text_decoration. Change treatment of cursor drawing to
15821 accommodate underlining, etc.
15823 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15825 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15828 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15830 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15831 Without this fix, if a signal arrives just after memory fills up,
15832 'malloc' might be invoked reentrantly.
15834 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15835 In other words, assume that every image size is allowed, on non-X
15836 hosts. This assumption is probably wrong, but it lets Emacs compile.
15838 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15840 * regex.c (re_iswctype): Convert return values to boolean.
15842 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15844 * xdisp.c (compute_display_string_pos): Don't use cached display
15845 string position if the buffer had its restriction changed.
15848 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15850 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15852 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15854 Integer signedness and overflow and related fixes. (Bug#9079)
15856 * bidi.c: Integer size and overflow fixes.
15857 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15858 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15859 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15860 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15861 (bidi_find_other_level_edge):
15862 Use ptrdiff_t instead of EMACS_INT where either will do.
15863 This works better on 32-bit hosts configured --with-wide-int.
15864 (bidi_cache_ensure_space): Check for size-calculation overflow.
15865 Use % rather than repeated addition, for better worst-case speed.
15866 Don't set bidi_cache_size until after xrealloc returns, because it
15868 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15869 (bidi_cache_ensure_space): Also check that the bidi cache size
15870 does not exceed that of the largest Lisp string or buffer. See Eli
15871 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15873 * alloc.c (__malloc_size_t): Remove.
15874 All uses replaced by size_t. See Andreas Schwab's note
15875 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15877 * image.c: Improve checking for integer overflow.
15878 (check_image_size): Assume that f is nonnull, since
15879 it is always nonnull in practice. This is one less thing to
15880 worry about when checking for integer overflow later.
15881 (x_check_image_size): New function, which checks for integer
15882 overflow issues inside X.
15883 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15884 This removes the need for a memory_full check.
15885 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15886 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15887 (xbm_read_bitmap_data): Change locals back to 'int', since
15888 their values must fit in 'int'.
15889 (xpm_load_image, png_load, tiff_load):
15890 Invoke x_create_x_image_and_pixmap earlier,
15891 to avoid much needless work if the image is too large.
15892 (tiff_load): Treat overly large images as if
15893 x_create_x_image_and_pixmap failed, not as malloc failures.
15894 (gs_load): Use x_check_image_size.
15896 * gtkutil.c: Omit integer casts.
15897 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15898 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15900 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15902 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15903 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15904 would wrongly return t on a 64-bit host.
15906 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15907 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15908 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15909 and therefore cause GCC to emit a bogus diagnostic in some cases.
15911 * image.c: Integer signedness and overflow and related fixes.
15912 This is not an exhaustive set of fixes, but it's time to
15913 record what I've got.
15914 (lookup_pixel_color, check_image_size): Remove redundant decls.
15915 (check_image_size): Don't assume that arbitrary EMACS_INT values
15916 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15917 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15918 (tiff_load, imagemagick_load_image):
15919 Check for overflow in size calculations.
15920 (x_create_x_image_and_pixmap): Remove unnecessary test for
15921 xmalloc returning NULL; that can't happen.
15922 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15923 (xpm_color_bucket): Use better integer hashing function.
15924 (xpm_cache_color): Don't possibly over-allocate memory.
15925 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15926 (gif_memory_source):
15927 Use ptrdiff_t, not int or size_t, to record sizes.
15928 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15929 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15930 either works, as we prefer signed integers.
15931 (tiff_read_from_memory, tiff_write_from_memory):
15932 Return tsize_t, not size_t, since that's what the TIFF API wants.
15933 (tiff_read_from_memory): Don't fail simply because the read would
15934 go past EOF; instead, return a short read.
15935 (tiff_load): Omit no-longer-needed casts.
15936 (Fimagemagick_types): Don't assume size fits into 'int'.
15938 Improve hashing quality when configured --with-wide-int.
15939 * fns.c (hash_string): New function, taken from sxhash_string.
15940 Do not discard information about ASCII character case; this
15941 discarding is no longer needed.
15942 (sxhash-string): Use it. Change sig to match it. Caller changed.
15943 * lisp.h: Declare it.
15944 * lread.c (hash_string): Remove, since we now use fns.c's version.
15945 The fns.c version returns a wider integer if --with-wide-int is
15946 specified, so this should help the quality of the hashing a bit.
15948 * emacs.c: Integer overflow minor fix.
15949 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15950 Define only if GNU_LINUX.
15951 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15953 * dispnew.c: Integer signedness and overflow fixes.
15954 Remove unnecessary forward decls, that were a maintenance hassle.
15955 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15957 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15958 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15959 (prepare_desired_row, line_draw_cost):
15960 Use int, not unsigned, where either works.
15961 (save_current_matrix, restore_current_matrix):
15962 Use ptrdiff_t, not size_t, where either works.
15963 (init_display): Check for overflow more accurately, and without
15964 relying on undefined behavior.
15966 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15967 Remove, replacing with the new symbols in lisp.h. All uses changed.
15968 * fileio.c (make_temp_name):
15969 * filelock.c (lock_file_1, lock_file):
15970 * xdisp.c (message_dolog):
15971 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15972 Use pMd etc. instead.
15973 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15974 replacing the pWIDE etc. symbols removed from editfns.c.
15976 * keyboard.h (num_input_events): Now uintmax_t.
15977 This is (very slightly) less likely to mess up due to wraparound.
15980 * buffer.c: Integer signedness fixes.
15981 (alloc_buffer_text, enlarge_buffer_text):
15982 Use ptrdiff_t rather than size_t when either will do, as we prefer
15985 * alloc.c: Integer signedness and overflow fixes.
15986 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15987 (__malloc_size_t): Default to size_t, not to int.
15988 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15989 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15990 Prefer ptrdiff_t to size_t when either would do, as we prefer
15992 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15993 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15994 Now const. Initialize with values that are in range even if char
15996 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15997 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15998 These functions do the right thing with sizes > 2**32.
15999 (check_depth): Now ptrdiff_t, not int.
16000 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16001 Adjust to new way of storing sizes. Check for size overflow bugs
16003 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16004 slightly wrong anyway, as it missed one instance of
16005 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16006 (refill_memory_reserve): Omit needless cast to size_t.
16007 (mark_object_loop_halt): Mark as externally visible.
16009 * xselect.c: Integer signedness and overflow fixes.
16010 (Fx_register_dnd_atom, x_handle_dnd_message):
16011 Use ptrdiff_t, not size_t, since we prefer signed.
16012 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16013 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16014 x_dnd_atoms_size and x_dnd_atoms_length.
16016 * doprnt.c: Prefer signed to unsigned when either works.
16018 * doprnt.c (doprnt):
16020 * xdisp.c (vmessage):
16021 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16022 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16023 prefer signed arithmetic to avoid comparison confusion.
16024 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16025 but is a bit tricky.
16027 Assume freestanding C89 headers, string.h, stdlib.h.
16028 * data.c, doprnt.c, floatfns.c, print.c:
16029 Include float.h unconditionally.
16030 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16031 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16032 * regex.c: Likewise for stddef.h, string.h.
16033 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16034 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16035 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16036 (STDC_HEADERS): Remove obsolete defines.
16037 * sysdep.c: Include limits.h unconditionally.
16039 Assume support for memcmp, memcpy, memmove, memset.
16040 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16041 * regex.c (memcmp, memcpy):
16042 Remove; we assume C89 now.
16044 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16045 (__malloc_safe_bcopy): Remove; no longer needed.
16047 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16048 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16049 well either way, and we prefer signed to unsigned.
16051 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16053 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16054 closes the connection while we're reading (bug#9182).
16056 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16058 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16059 are specified (Bug#9168).
16061 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16063 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16064 Found by GCC static checking and --with-wide-int on a 32-bit host.
16066 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16068 * xdisp.c (compute_display_string_pos): Fix logic of caching
16069 previous display string position. Initialize cached_prev_pos to
16070 -1. Fixes slow-down at the beginning of a buffer.
16072 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16074 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16075 for attrs[LFACE_FONTSET_INDEX].
16077 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16079 * xml.c (parse_region): Remove unused local
16080 that was recently introduced.
16082 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16084 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16085 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16087 * xdisp.c (move_it_in_display_line_to): Record the best matching
16088 position for TO_CHARPOS while scanning the line, and restore it on
16089 exit if none of the characters scanned was an exact match.
16090 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16091 when exact match is impossible due to invisible text, and the
16092 lines are truncated.
16094 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16096 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16099 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16101 Fix a significant slow-down of cursor motion with C-n, C-p,
16102 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16103 auto-repeat under bidi redisplay in fontified buffers.
16104 * xdisp.c (compute_stop_pos_backwards): New function.
16105 (next_element_from_buffer): Call compute_stop_pos_backwards to
16106 find a suitable prev_stop when we find ourselves before
16108 (reseat): Don't look for prev_stop, as that could mean a very long
16110 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16111 <cached_disp_overlay_modiff>: Cache for last found display string
16113 (compute_display_string_pos): Return the cached position if asked
16114 about the same buffer in the same area of character positions, and
16115 the buffer wasn't changed since the time the display string
16116 position was cached.
16118 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16120 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16121 is an integer, which is important for empty lines. (Bug#9149)
16123 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16125 * frame.c (Fmodify_frame_parameters): In tty case, update the
16126 default face if necessary (Bug#4238).
16128 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16130 * editfns.c (Fstring_to_char): No need to explain what a character
16131 is in the docstring (Bug#6576).
16133 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16135 * xml.c (parse_region): Make sure we always return a tree.
16137 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16139 * xml.c (parse_region): If a document contains only comments,
16142 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16144 * xml.c (make_dom): Return comments, too.
16146 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16149 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16150 and the surrounding thread.
16151 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16152 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16153 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16155 * s/openbsd.h (BROKEN_SIGIO): Define.
16156 * unexelf.c (unexec) [__OpenBSD__]:
16157 Don't update the .mdebug section of the Alpha COFF symbol table.
16159 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16161 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16164 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16166 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16167 This fixes some race conditions on the permissions of any newly
16170 * alloc.c (valid_pointer_p): Use pipe, not open.
16171 This fixes some permissions issues when debugging.
16173 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16174 If fchown fails to set both uid and gid, try to set just gid,
16175 as that is sometimes allowed. Adjust the file's mode to eliminate
16176 setuid or setgid bits that are inappropriate if fchown fails.
16178 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16180 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16181 to compare Lisp_Objects.

16186 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16188 * lread.c (read_integer): Unread even EOF character.
16189 (read1): Likewise. Properly record start position of symbol.
16191 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16192 symbol character follows.
16194 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16196 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16197 This works around a problem with the previous change to Fcopy_file.
16198 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16199 and without this change, GCC might complain about discarding
16200 fchown's return value.
16202 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16204 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16206 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16208 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16210 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16212 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16213 it's used from the C level.
16215 * process.c: Use the same condition for POLL_FOR_INPUT in both
16216 keyboard.c and process.c (bug#1858).
16218 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16220 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16221 (Fgnutls_boot): Use it.
16223 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16225 * doc.c (Fsubstitute_command_keys): Revert last change.
16227 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16229 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16230 quotes the next character, and doesn't affect other longer
16231 sequences (bug#8935).
16233 * lread.c (syms_of_lread): Clarify that is isn't only
16234 `eval-buffer' and `eval-defun' that's affected by
16235 `lexical-binding' (bug#8460).
16237 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16239 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16240 bidi redisplay when a line includes both an image and is truncated.
16242 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16244 Fix minor problems found by static checking.
16245 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16246 (elsz): Now a signed constant, not a size_t var. We prefer signed
16247 types to unsigned, to avoid integer comparison confusion. Without
16248 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16249 "cannot optimize loop, the loop counter may overflow", a symptom
16251 * indent.c (Fvertical_motion): Mark locals as initialized.
16252 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16254 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16256 * search.c (Fre_search_backward): Mention `case-fold-search' in
16257 all the re_search_* functions (bug#8138).

16277 buffer position was specified. Initialize paragraph_embedding to
16279 (reseat_to_string): Initialize the bidi iterator.
16280 (display_string): If we need to ignore text properties of
16281 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16282 original value of -1 will not work with bidi.)
16283 (compute_display_string_pos): First arg is now struct
16284 `text_pos *'; all callers changed. Support display properties on
16286 (compute_display_string_end): Support display properties on Lisp
16288 (init_iterator, reseat_1, reseat_to_string): Initialize the
16289 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16290 when iterating on a string not from display properties).
16291 (compute_display_string_pos, compute_display_string_end):
16292 Fix calculation of the object to scan. Fixes an error when using
16294 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16295 base_level_stop; instead, set base_level_stop to BEGV.
16296 Fixes crashes in vertical-motion.
16297 (next_element_from_buffer): Improve commentary for when
16298 the iterator is before prev_stop.
16299 (init_iterator): Initialize bidi_p from the default value of
16300 bidi-display-reordering, not from buffer-local value. Use the
16301 buffer-local value only if initializing for buffer iteration.
16302 (handle_invisible_prop): Support invisible properties on strings
16303 that are being bidi-reordered.
16304 (set_iterator_to_next): Support bidi reordering of C strings and
16306 (next_element_from_string): Support bidi reordering of Lisp

16310 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16311 (init_iterator): Don't initialize it->bidi_p for strings
16313 (reseat_to_string): Initialize it->bidi_p for strings here.

16320 character that is not the first one in the visual order.
16321 (get_visually_first_element): New function, refactored from common
16322 parts of next_element_from_buffer, next_element_from_string, and
16323 next_element_from_c_string.
16324 (tool_bar_lines_needed, redisplay_tool_bar)
16325 (display_menu_bar): Force left-to-right direction. Add a FIXME
16326 comment for making that be controlled by a user option.
16327 (push_it, pop_it): Save and restore the state of the
16328 bidi iterator. Save and restore the bidi_p flag.
16329 (pop_it): Iterate out of display property for string iteration as

16332 (handle_single_display_spec): Set up it->bidi_it for iteration
16333 over a display string, and call bidi_init_it.

16335 (get_overlay_strings_1, push_display_prop): Set up the bidi
16336 iterator for displaying display or overlay strings.
16337 (forward_to_next_line_start): Don't use the shortcut if
16339 (back_to_previous_visible_line_start): If handle_display_prop
16340 pushed the iterator stack, restore the internal state of the bidi
16341 iterator by calling bidi_pop_it same number of times.
16342 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16343 and we are bidi-iterating, don't decrement the iterator position;
16344 instead, set the first_elt flag in the bidi iterator, to produce
16346 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16347 (push_display_prop): xassert that we are iterating a buffer.
16348 (push_it, pop_it): Save and restore paragraph_embedding member.
16349 (handle_single_display_spec, next_overlay_string)
16350 (get_overlay_strings_1, reseat_1, reseat_to_string)
16351 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16352 correctly. Don't assume unibyte strings are not bidi-reordered.
16353 (compute_display_string_pos)
16354 (compute_display_string_end): Fix handling the case of C string.
16355 (push_it, pop_it): Save and restore from_disp_prop_p.

16361 property. Fix a typo in popping stretch info. Add an assertion
16362 for verifying that the iterator position is in sync with the bidi
16364 (handle_single_display_spec, get_overlay_strings_1)

16382 (move_it_in_display_line_to): If iterator ended up at
16383 EOL, but we never saw any buffer positions smaller than
16384 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16385 motion in bidi-reordered lines.

16387 immediately before the call to set_iterator_to_next. Fixes cursor
16388 motion in bidi-reordered lines with stretch glyphs and strings
16389 displayed in margins. (Bug#8133) (Bug#8867)
16390 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16392 (pos_visible_p): Support positions in bidi-reordered lines.
16393 Save and restore bidi cache.
16395 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16396 (bidi_paragraph_info): Delete unused struct.

16414 Support iteration over a string.
16415 (bidi_set_sor_type, bidi_resolve_explicit_1)
16416 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16417 can now be zero (for strings); special values 0 and -1 were
16418 changed to -1 and -2, respectively.
16419 (bidi_char_at_pos): New function.
16420 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16508 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16509 The old code sometimes used this field without initializing it.
16511 * alloc.c (gc_sweep): Don't read past end of array.
16512 In theory, the old code could also have corrupted Emacs internals,
16513 though it'd be very unlikely.

16776 (clone_per_buffer_values): Don't assume that

16778 This isn't true in general, and it's particularly not true
16779 if Emacs is configured with --with-wide-int.
16780 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16781 New macros, used in the buffer.c change.

16817 Random fixes. E.g., (random) never returned negative values.
16818 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16819 subseconds part to the entropy, as that's a bit more random.
16820 Prefer signed to unsigned, since the signedness doesn't matter and
16821 in general we prefer signed. When given a limit, use a
16822 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16823 latter isn't right if USE_2_TAGS_FOR_INTS.
16824 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16825 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16837 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16838 This is more efficient than Ffile_directory_p and avoids a minor race.
16840 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16842 * buffer.c (Foverlay_put): Say what the return value is
16845 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16846 is a directory before asking whether to use the file name

16849 error be more correct.
16851 * fns.c (Frequire): Remove the mention of the .gz files, since
16852 that's installation-specific, but keep the mention of

16865 Qgnutls_bootprop_verify_error (which is no longer used).
16867 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16868 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16869 Also (re)move comments that are misplaced or no longer relevant.

16898 * lread.c (syms_of_lread): Mention single symbols defined by
16899 `defvar' or `defconst' (bug#7154).
16901 * fns.c (Frequire): Mention .el.gz files (bug#7314).
16902 (Frequire): Mention get-load-suffixes.

16970 * eval.c (struct backtrace): Simplify and port the data structure.
16971 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16972 signed bit field, as this assumption is not portable and it makes
16973 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16974 "char debug_on_exit : 1" as this is not portable either; instead,
16975 use the portable "unsigned int debug_on_exit : 1". Remove unused
16976 member evalargs. Remove obsolete comments about cc bombing out.
16978 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17046 (emacs_fixed_new): Set priv->f to argument.
17047 (emacs_fixed_get_preferred_width)
17048 (emacs_fixed_get_preferred_height): Use min_width/height from
17049 frames size_hint to set minimum and natural (Bug#8919).
17050 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17051 and use min_width/height from frames size_hint to set
17052 min_width/height (Bug#8919).

17072 Use gnulib's dup2 module instead of rolling our own.
17073 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

17140 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17142 Integer and buffer overflow fixes (Bug#8873).
17144 * print.c (printchar, strout): Check for string overflow.
17145 (PRINTPREPARE, printchar, strout):
17146 Don't set size unless allocation succeeds.
17148 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17149 for sizes. Check for string overflow more accurately.
17150 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17152 * macros.c: Integer and buffer overflow fixes.
17153 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17154 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17158 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17160 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17162 * lread.c: Integer overflow fixes.
17163 (read_integer): Radix is now EMACS_INT, not int,
17164 to improve quality of diagnostics for out-of-range radices.
17165 Calculate buffer size correctly for out-of-range radices.
17166 (read1): Check for integer overflow in radices, and in
17167 read-circle numbers.
17168 (read_escape): Avoid int overflow.
17169 (Fload, openp, read_buffer_size, read1)
17170 (substitute_object_recurse, read_vector, read_list, map_obarray):
17171 Use ptrdiff_t, not int, for sizes.

17186 2011-06-22 Leo Liu <sdl.web@gmail.com>
17188 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17189 Move to minibuffer.el.
17191 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17193 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17194 The following patches are for when GLYPH_DEBUG && !XASSERT.
17195 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17196 * dispnew.c (flush_stdout):
17197 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17198 Mark as externally visible.
17199 * dispnew.c (check_window_matrix_pointers): Now static.
17200 * dispnew.c (window_to_frame_vpos):
17201 * xfns.c (unwind_create_frame):
17202 * xterm.c (x_check_font): Remove unused local.
17203 * scroll.c (CHECK_BOUNDS):
17204 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17205 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17206 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17207 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17208 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17210 (debug_method_add): Use va_list and vsprintf rather than relying
17211 on undefined behavior with wrong number of arguments.
17212 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17213 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17214 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17215 since we're not interested in debugging glyphs with old libraries.
17216 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17217 GCC 4.6.0's static checking.
17219 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17221 Integer overflow and signedness fixes (Bug#8873).

17233 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17235 * xfaces.c (load_pixmap):
17236 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17237 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17238 (.bitmaps_last, struct x_output.icon_bitmap):
17239 Use ptrdiff_t, not int, for bitmap indexes.
17240 (x_allocate_bitmap_record): Check for size overflow.
17241 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17243 Use ptrdiff_t, not int, for overlay counts.
17244 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17245 * editfns.c (overlays_around, get_pos_property):

17251 (Fnext_overlay_change, Fprevious_overlay_change)
17252 (mouse_face_overlay_overlaps, Foverlays_in):
17253 Use ptrdiff_t, not int, for sizes.
17254 (overlays_at, overlays_in): Check for size-calculation overflow.
17256 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17258 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17259 (x_session_initialize): Do not assume string length fits in int.
17261 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17262 This is unlikely, but can occur if DPI is outlandish.
17264 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17265 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17267 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17268 * xrdb.c (magic_file_p, search_magic_path):
17269 Omit last arg SUFFIX; it was always 0. All callers changed.
17270 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17272 * xfont.c (xfont_match): Avoid need for strlen.
17274 * xfns.c: Don't assume strlen fits in int.

17277 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17278 not unsigned long, as we prefer signed integers. All callers changed.
17279 Detect integer overflow in repeat count.
17280 (message_dolog): Don't assume print length fits in 39 bytes.
17281 (display_mode_element): Don't assume strlen fits in int.
17283 * termcap.c: Don't assume sizes fit in int and never overflow.
17284 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17285 (gobble_line): Check for size-calculation overflow.
17287 * minibuf.c (Fread_buffer):
17288 * lread.c (intern, intern_c_string):
17289 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

17302 * filelock.c: Fix some buffer overrun and integer overflow issues.
17303 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17304 Reformulate so as not to need the command string.
17305 Invoke gzip -cd rather than gunzip, as it's more portable.
17306 (lock_info_type, lock_file_1, lock_file):
17307 Don't assume pid_t and time_t fit in unsigned long.
17308 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17309 (current_lock_owner): Prefer signed type for sizes.
17310 Use memcpy, not strncpy, where memcpy is what is really wanted.
17311 Don't assume (via atoi) that time_t and pid_t fit in int.
17312 Check for time_t and/or pid_t out of range, e.g., via a network share.
17313 Don't alloca where an auto var works fine.
17315 * fileio.c: Fix some integer overflow issues.
17316 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17317 Don't assume string length fits in int.
17318 (directory_file_name): Don't assume string length fits in long.
17319 (make_temp_name): Don't assume pid fits in int, or that its print
17320 length is less than 20.
17322 * data.c (Fsubr_name): Rewrite to avoid a strlen call.

17339 (Fgetenv_internal):
17340 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17342 * lread.c (invalid_syntax): Omit length argument.
17343 All uses changed. This doesn't fix a bug, but it simplifies the
17344 code away from its former Hollerith-constant appearance, and it's
17345 one less 'int' to worry about when looking at integer-overflow issues.
17346 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17348 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17349 This didn't break anything, but it didn't help either.
17350 It's confusing to put a bogus integer in a place where the actual
17351 value does not matter.
17352 (LIST_END_P): Remove unused macro and its bogus comment.
17353 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17355 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17356 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17358 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17359 We prefer signed types, and the value cannot exceed the EMACS_INT
17360 range anyway (because otherwise the length would not be representable).
17361 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17362 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17363 This avoids a GCC warning when WIDE_EMACS_INT.
17365 * indent.c (sane_tab_width): New function.
17366 (current_column, scan_for_column, Findent_to, position_indentation)
17367 (compute_motion): Use it. This is just for clarity.
17368 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17370 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17372 * lisp.h (lint_assume): New macro.
17373 * composite.c (composition_gstring_put_cache):
17374 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17376 * editfns.c, insdel.c:
17377 Omit unnecessary forward decls, to simplify future changes.
17379 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17381 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17383 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17384 Use much-faster test for byte-length change.
17385 Don't assume string byte-length fits in 'int'.
17386 Check that character arg fits in 'int'.
17387 (mapcar1): Declare byte as byte, for clarity.
17389 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17391 * fns.c (concat): Catch string overflow earlier.
17392 Do not rely on integer wraparound.
17394 * dispextern.h (struct it.overlay_strings_charpos)
17395 (struct it.selective): Now EMACS_INT, not int.
17396 * xdisp.c (forward_to_next_line_start)
17397 (back_to_previous_visible_line_start)
17398 (reseat_at_next_visible_line_start, next_element_from_buffer):
17399 Don't arbitrarily truncate the value of 'selective' to int.
17401 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17403 * composite.c: Don't truncate sizes to 'int'.
17404 (composition_gstring_p, composition_reseat_it)
17405 (composition_adjust_point): Use EMACS_INT, not int.
17406 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17407 not EMACS_UINT, for indexes.
17409 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17411 * buffer.c: Include <verify.h>.
17412 (struct sortvec.priority, struct sortstr.priority):
17413 Now EMACS_INT, not int.
17414 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17415 (struct sortstr.size, record_overlay_string)
17416 (struct sortstrlist.size, struct sortlist.used):
17417 Don't truncate size to int.
17418 (record_overlay_string): Check for size-calculation overflow.
17419 (init_buffer_once): Check at compile-time, not run-time.
17421 2011-06-22 Jim Meyering <meyering@redhat.com>
17423 Don't leak an XBM-image-sized buffer
17424 * image.c (xbm_load): Free the image buffer after using it.
17426 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17429 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17430 that Sun C diagnosed.
17431 * fns.c (secure_hash): Fix pointer signedness issue.
17432 * intervals.c (static_offset_intervals): New function.
17433 (offset_intervals): Use it.
17435 2011-06-21 Leo Liu <sdl.web@gmail.com>
17438 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17441 * fns.c (secure_hash): Rename from crypto_hash_function and change
17442 the first arg to accept symbols.
17443 (Fsecure_hash): New primitive.
17444 (syms_of_fns): New symbols.
17446 2011-06-20 Deniz Dogan <deniz@dogan.se>
17448 * process.c (Fset_process_buffer): Clarify return value in
17451 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17453 * dispnew.c (add_window_display_history): Use BVAR.
17455 * xdisp.c (debug_method_add): Use BVAR.
17456 (check_window_end, dump_glyph_matrix, dump_glyph)
17457 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17459 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17462 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17463 check till after the cache is created in init_frame_faces.
17465 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17467 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17469 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17471 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17472 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17473 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17475 Improve buffer-overflow checking (Bug#8873).
17476 * fileio.c (Finsert_file_contents):
17477 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17478 Remove the old (too-loose) buffer overflow checks.
17479 They weren't needed, since make_gap checks for buffer overflow.
17480 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17481 The old code merely checked for Emacs fixnum overflow, and relied
17482 on undefined (wraparound) behavior. The new code avoids undefined
17483 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17485 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17486 Tune. Don't use wider integers than needed. Don't use alloca.
17487 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17489 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17491 * insdel.c, lisp.h (buffer_overflow): New function.
17492 (insert_from_buffer_1, replace_range, replace_range_2):
17493 * insdel.c (make_gap_larger):
17494 * editfns.c (Finsert_char):
17495 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17497 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17499 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17501 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17503 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17504 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17506 * fileio.c: Don't assume EMACS_INT fits in off_t.
17507 (emacs_lseek): New static function.
17508 (Finsert_file_contents, Fwrite_region): Use it.
17509 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17511 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17513 * fns.c: Don't overflow int when computing a list length.
17514 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17515 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17516 truncation on 64-bit hosts. Check for QUIT every
17517 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17518 faster and is responsive enough.
17519 (Flength): Report an error instead of overflowing an integer.
17520 (Fsafe_length): Return a float if the value is not representable
17521 as a fixnum. This shouldn't happen except in contrived situations.
17522 (Fnthcdr, Fsort): Don't assume list length fits in int.
17523 (Fcopy_sequence): Don't assume vector length fits in int.
17525 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17526 (header_size, word_size): New constants.
17527 (allocate_vectorlike): Don't check size overflow here.
17528 (allocate_vector): Check it here instead, since this is the only
17529 caller of allocate_vectorlike that could cause overflow.
17530 Check that the new vector's length is representable as a fixnum.
17532 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17533 The previous code was bogus. For example, next_almost_prime (32)
17534 returned 39, which is undesirable as it is a multiple of 3; and
17535 next_almost_prime (24) returned 25, which is a multiple of 5 so
17536 why was the code bothering to check for multiples of 7?
17538 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17540 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17542 Variadic C functions now count arguments with ptrdiff_t.
17543 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17544 Back then I didn't know that the Emacs coding style prefers signed int.
17545 Also, in the meantime I found a few more instances where arguments
17546 were being counted with int, which may truncate counts on 64-bit
17547 machines, or EMACS_INT, which may be unnecessarily wide.
17548 * lisp.h (struct Lisp_Subr.function.aMANY)
17549 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17550 Arg counts are now ptrdiff_t, not size_t.
17551 All variadic functions and their callers changed accordingly.
17552 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17553 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17554 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17555 * callint.c (Fcall_interactively): Check arg count for overflow,
17556 to avoid potential buffer overrun. Use signed char, not 'int',
17557 for 'varies' array, so that we needn't bother to check its size
17558 calculation for overflow.
17559 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17560 * eval.c (apply_lambda):
17561 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17562 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17563 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17565 * callint.c (Fcall_interactively): Don't use index var as event count.
17567 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17568 * mem-limits.h (SIZE): Remove; no longer used.
17570 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17572 Remove unnecessary casts.
17573 * xterm.c (x_term_init):
17574 * xfns.c (x_set_border_pixel):
17575 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17576 These aren't needed now that we assume ANSI C.
17578 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17579 It's more likely to cause problems (due to unsigned overflow)
17582 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17584 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17586 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17588 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17590 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17592 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17594 GLYPH_CODE_FACE returns EMACS_INT, not int.
17595 * dispextern.h (merge_faces):
17596 * xfaces.c (merge_faces):
17597 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17598 Don't assume EMACS_INT fits in int.
17600 * character.h (CHAR_VALID_P): Remove unused parameter.
17601 * fontset.c, lisp.h, xdisp.c: All uses changed.
17603 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17605 * fns.c (concat): Minor tuning based on overflow analysis.
17606 This doesn't fix any bugs. Use int to hold character, instead
17607 of constantly refetching from Emacs object. Use XFASTINT, not
17608 XINT, for value known to be a character. Don't bother comparing
17609 a single byte to 0400, as it's always less.
17611 * floatfns.c (Fexpt):
17612 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17614 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17617 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17619 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17620 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17621 incorrectly succeed when S was a string, because 4294967386 was
17622 truncated before it was used.
17624 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17625 Otherwise, an out-of-range integer could cause undefined behavior
17628 * composite.c: Use int, not EMACS_INT, for characters.
17629 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17630 EMACS_INT, for values that are known to be in character range.
17631 This doesn't fix any bugs but is the usual style inside Emacs and
17632 may generate better code on 32-bit machines.
17634 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17635 This is for reasons similar to the recent CHAR_STRING fix.
17636 * charset.c (Fencode_char): Check that character arg is actually
17637 a character. Pass an int to ENCODE_CHAR.
17638 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17639 wider than 'int', as a compile-time check to prevent future regressions
17642 * character.c (char_string): Remove unnecessary casts.
17644 Make sure a 64-bit char is never passed to CHAR_STRING.
17645 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17646 by silently ignoring the top 32 bits, allowing some values
17647 that were far too large to be valid characters.
17648 * character.h: Include <verify.h>.
17649 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17650 arguments are no wider than unsigned, as a compile-time check
17651 to prevent future regressions in this area.
17653 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17654 (Fsubst_char_in_region):
17656 * xdisp.c (decode_mode_spec_coding):
17657 Adjust to CHAR_STRING's new requirement.
17658 * editfns.c (Finsert_char, Fsubst_char_in_region):
17659 * fns.c (concat): Check that character args are actually
17660 characters. Without this test, these functions did the wrong
17661 thing with wildly out-of-range values on 64-bit hosts.
17663 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17664 These casts should not be needed on 32-bit hosts, either.
17665 * keyboard.c (read_char):
17666 * lread.c (Fload): Remove casts to unsigned.
17668 * lisp.h (UNSIGNED_CMP): New macro.
17669 This fixes comparison bugs on 64-bit hosts.
17670 (ASCII_CHAR_P): Use it.
17671 * casefiddle.c (casify_object):
17672 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17673 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17674 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17675 * dispextern.h (FACE_FROM_ID):
17676 * keyboard.c (read_char): Use UNSIGNED_CMP.
17678 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17679 not to EMACS_INT, to avoid GCC warning.
17681 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17683 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17684 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17685 isn't needed on 32-bit machines.
17687 * buffer.c (Fgenerate_new_buffer_name):
17688 Use EMACS_INT for count, not int.
17689 (advance_to_char_boundary): Return EMACS_INT, not int.
17691 * data.c (Qcompiled_function): Now static.
17693 * window.c (window_body_lines): Now static.
17695 * image.c (gif_load): Rename local to avoid shadowing.
17697 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17698 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17699 * alloc.c (make_save_value): Integer argument is now of type
17700 ptrdiff_t, not int.
17701 (mark_object): Use ptrdiff_t, not int.
17702 * lisp.h (pD): New macro.
17703 * print.c (print_object): Use it.
17705 * alloc.c: Use EMACS_INT, not int, to count objects.
17706 (total_conses, total_markers, total_symbols, total_vector_size)
17707 (total_free_conses, total_free_markers, total_free_symbols)
17708 (total_free_floats, total_floats, total_free_intervals)
17709 (total_intervals, total_strings, total_free_strings):
17710 Now EMACS_INT, not int. All uses changed.
17711 (Fgarbage_collect): Compute overall total using a double, so that
17712 integer overflow is less likely to be a problem. Check for overflow
17713 when converting back to an integer.
17714 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17715 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17716 These were 'int' variables that could overflow on 64-bit hosts;
17717 they were never used, so remove them instead of repairing them.
17718 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17719 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17720 Previously, this ceilinged at INT_MAX, but that doesn't work on
17722 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17724 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17725 (allocate_vectorlike): Check for ptrdiff_t overflow.
17726 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17727 when a (possibly-narrower) signed value would do just as well.
17728 We prefer using signed arithmetic, to avoid comparison confusion.
17730 * alloc.c: Catch some string size overflows that we were missing.
17731 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17732 for convenience in STRING_BYTES_MAX.
17733 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17734 The definition here is exact; the one in lisp.h was approximate.
17735 (allocate_string_data): Check for string overflow. This catches
17736 some instances we weren't catching before. Also, it catches
17737 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17738 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17739 and ptrdiff_t and EMACS_INT are both 64 bits.
17741 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17742 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17743 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17745 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17747 * alloc.c (Fmake_string): Check for out-of-range init.
17749 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17751 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17753 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17755 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17756 xg_get_default_scrollbar_width.
17758 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17759 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17760 (style_changed_cb): Call update_theme_scrollbar_width and call
17761 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17762 all frames (Bug#8505).
17763 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17764 Call gtk_window_set_resizable if HAVE_GTK3.
17765 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17766 and height if HAVE_GTK3 (Bug#8505).
17767 (scroll_bar_width_for_theme): New variable.
17768 (update_theme_scrollbar_width): New function.
17769 (xg_get_default_scrollbar_width): Move code to
17770 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17771 (xg_initialize): Call update_theme_scrollbar_width.
17773 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17775 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17777 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17779 * frame.c (make_frame): Call other_buffer_safely instead of
17782 * window.c (temp_output_buffer_show): Call display_buffer with
17783 second argument Vtemp_buffer_show_specifiers and reset latter
17784 immediately after the call.
17785 (Vtemp_buffer_show_specifiers): New variable.
17786 (auto_window_vscroll_p, next_screen_context_lines)
17787 (Vscroll_preserve_screen_position): Remove leading asterisks from
17790 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
17792 Fix minor problems found by GCC 4.6.0 static checking.
17793 * buffer.c (Qclone_number): Remove for now, as it's unused.
17794 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
17795 (record_buffer): Remove unused local.
17796 * frame.c (other_visible_frames, frame_buffer_list): Now static.
17797 (set_frame_buffer_list): Remove; unused.

18242 (Fselected_window, select_window, Fselect_window): Move up in
18243 code. Minor doc-string fixes.
18245 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18247 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18248 Do not assume that spare memory exists; that assumption is valid
18249 only if SYSTEM_MALLOC.
18250 (LARGE_REQUEST): New macro, so that the issue of large requests
18251 is separated from the issue of spare memory.
18253 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
18255 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

18270 min width by calling x_set_scroll_bar_default_width (Bug#8505).
18272 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
18274 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
18276 2011-06-04 Chong Yidong <cyd@stupidchicken.com>
18278 * xselect.c (x_clipboard_manager_save): Remove redundant arg.
18279 (x_clipboard_manager_save): Add return value.
18280 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
18281 New error handlers.
18282 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18283 Obey Vx_select_enable_clipboard_manager. Catch errors in
18284 x_clipboard_manager_save (Bug#8779).
18285 (Vx_select_enable_clipboard_manager): New variable.
18286 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18288 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18290 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18292 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18294 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18295 in the current matrix if keep_current_p is non-zero.
18297 2011-06-04 Eli Zaretskii <eliz@gnu.org>
18299 * bidi.c (bidi_level_of_next_char): Fix last change.
18301 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18303 Support bidi reordering of text covered by display properties.
18305 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18306 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18307 (bidi_cache_search, bidi_cache_iterator_state)
18308 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18309 (bidi_level_of_next_char, bidi_move_to_visually_next):
18310 Support character positions inside a run of characters covered by a
18312 (bidi_paragraph_init, bidi_resolve_explicit_1)
18313 (bidi_level_of_next_char): Call bidi_fetch_char and
18314 bidi_fetch_char_advance instead of FETCH_CHAR and
18315 FETCH_CHAR_ADVANCE.
18316 (bidi_init_it): Initialize new members.
18317 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18319 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18320 instead of using explicit *_CHAR codes.
18321 (bidi_resolve_explicit, bidi_resolve_weak):
18322 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18323 bidirectional text is supported only in multibyte buffers.
18324 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18325 it to initialize the frame_window_p member of struct bidi_it.
18326 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18327 (bidi_resolve_explicit, bidi_resolve_weak)
18328 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
18329 bidi_it->nchars is non-positive.
18330 (bidi_level_of_next_char): Don't try to lookup the cache for the
18331 next/previous character if nothing is cached there yet, or if we
18332 were just reseat()'ed to a new position.
18334 * xdisp.c (set_cursor_from_row): Set start and stop points
18335 according to the row's direction when priming the loop that looks
18336 for the glyph on which to display cursor.
18337 (single_display_spec_intangible_p): Function deleted.
18338 (display_prop_intangible_p): Reimplement to call
18339 handle_display_spec instead of single_display_spec_intangible_p.
18340 Accept 3 additional arguments needed by handle_display_spec.
18341 This fixes incorrect cursor motion across display property with complex
18342 values: lists, `(when COND...)' forms, etc.
18343 (single_display_spec_string_p): Support property values that are
18344 lists with the argument STRING its top-level element.
18345 (display_prop_string_p): Fix the condition for processing a
18346 property that is a list to be consistent with handle_display_spec.
18347 (handle_display_spec): New function, refactored from the
18348 last portion of handle_display_prop.
18349 (compute_display_string_pos): Accept additional argument
18350 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18351 value of a `display' property is a "replacing spec".
18352 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18353 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18354 the display property, but just return a value indicating whether
18355 the display property will replace the characters it covers.
18356 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18357 frame_window_p members of struct bidi_it.
18358 (compute_display_string_pos, compute_display_string_end):
18360 (push_it): Accept second argument POSITION, where pop_it should
18361 jump to continue iteration.
18362 (reseat_1): Initialize bidi_it.disp_pos.
18364 * keyboard.c (adjust_point_for_property): Adjust the call to
18365 display_prop_intangible_p to its new signature.
18367 * dispextern.h (struct bidi_it): New member frame_window_p.
18368 (bidi_init_it): Update prototypes.
18369 (display_prop_intangible_p): Update prototype.
18370 (compute_display_string_pos, compute_display_string_end):
18371 Declare prototypes.
18372 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18375 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18377 Malloc failure behavior now depends on size of allocation.
18378 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18379 * lisp.h: Change signatures accordingly.
18380 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18381 All callers changed. (Bug#8762)
18383 * gnutls.c: Use Emacs's memory allocators.
18384 Without this change, the gnutls library would invoke malloc etc.
18385 directly, which causes problems on non-SYNC_INPUT hosts, and which
18386 runs afoul of improving memory_full behavior. (Bug#8761)
18387 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18388 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18389 xfree instead of the default malloc, realloc, free.
18390 (Fgnutls_boot): No need to check for memory allocation failure,
18391 since xmalloc does that for us.
18393 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18394 * category.c (hash_get_category_set):
18395 * ccl.c (ccl_driver):
18396 * charset.c (Fdefine_charset_internal):
18397 * charset.h (struct charset.hash_index):
18398 * composite.c (get_composition_id, gstring_lookup_cache)
18399 (composition_gstring_put_cache):
18400 * composite.h (struct composition.hash_index):
18401 * dispextern.h (struct image.hash):
18402 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
18403 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
18404 (hashfn_equal, hashfn_user_defined, make_hash_table)
18405 (maybe_resize_hash_table, hash_lookup, hash_put)
18406 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18407 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18408 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18409 * image.c (make_image, search_image_cache, lookup_image)
18410 (xpm_put_color_table_h):
18411 * lisp.h (struct Lisp_Hash_Table):
18412 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18413 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18414 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18415 * alloc.c (allocate_vectorlike):
18416 Check for overflow in vector size calculations.
18417 * ccl.c (ccl_driver):
18418 Check for overflow when converting EMACS_INT to int.
18419 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18420 need to be updated by these changes.
18421 * fns.c (make_hash_table, maybe_resize_hash_table):
18422 Check for integer overflow with large hash tables.
18423 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18424 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18425 (SXHASH_REDUCE): New macro.
18426 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18427 Use it instead of discarding useful hash info with large hash values.
18428 (sxhash_float): New function.
18429 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18430 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18431 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18432 Rewrite to use FIXNUM_BITS, as this simplifies things.
18433 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18434 Adjust signatures to match updated version of code.
18435 (consing_since_gc): Now EMACS_INT, since a single hash table can
18436 use more than INT_MAX bytes.
18438 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18440 Make it possible to build with GCC-4.6+ -O2 -flto.
18442 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18444 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18446 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18447 Call minibuffer-inactive-mode.
18449 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18451 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18452 Update dependencies.
18454 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18456 * data.c (init_data): Remove code for UTS, this system is not
18459 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18461 Don't force ./temacs to start in terminal mode.
18463 * frame.c (make_initial_frame): Initialize faces in all cases, not
18464 only when CANNOT_DUMP is defined.
18465 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18467 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18469 * dispnew.c (add_window_display_history): Use const for the string
18470 pointer. Remove declaration, not needed.
18472 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18474 Use 'inline', not 'INLINE'.
18475 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18476 * alloc.c, fontset.c (INLINE): Remove.
18477 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18478 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18479 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18480 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18481 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18483 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18485 Make it possible to run ./temacs.
18487 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18488 syms_of_callproc does the same thing. Remove test for
18489 "initialized", do it in the caller.
18490 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18492 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18494 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18495 (read_minibuf): Use get_minibuffer.
18496 (syms_of_minibuf): Use DEFSYM.
18497 (Qmetadata): New var.
18498 * data.c (Qbuffer): Don't make it static.
18499 (syms_of_data): Use DEFSYM.
18501 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18503 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18504 (CCL_CODE_MIN): New macro.
18506 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18508 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18510 * eval.c (Qdebug): Now static.
18511 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18512 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18513 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18515 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18517 * image.c: Various fixes to ImageMagick code comments.
18518 (Fimagemagick_types): Doc fix.
18520 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18522 Minor fixes prompted by GCC 4.6.0 warnings.
18524 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18526 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18527 (x_clipboard_manager_save_all): Move extern decl to ...
18528 * xterm.h: ... here, so that it can be checked for consistency.
18530 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18532 * xselect.c (x_clipboard_manager_save_frame)
18533 (x_clipboard_manager_save_all): New functions.
18534 (Fx_clipboard_manager_save): Lisp function deleted.
18536 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18537 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18539 * xterm.h: Update prototype.
18541 2011-05-28 William Xu <william.xwl@gmail.com>
18543 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18544 exiting (Bug#8239).
18546 2011-05-28 Jim Meyering <meyering@redhat.com>
18548 Avoid a sign-extension bug in crypto_hash_function.
18549 * fns.c (to_uchar): Define.
18550 (crypto_hash_function): Use it to convert some newly-signed
18551 variables to unsigned, to avoid sign-extension bugs. For example,
18552 without this change, (md5 "truc") would evaluate to
18553 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18554 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18555 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18557 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18559 Integer overflow fixes.
18561 * dbusbind.c: Serial number integer overflow fixes.
18562 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18563 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18564 to hold a serial number that is too large for a fixnum.
18565 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18566 Check for serial numbers out of range. Decode any serial number
18567 that was so large that it became a float. (Bug#8722)
18569 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18570 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18571 Use XFASTINT rather than XUINT when numbers are nonnegative.
18572 (xd_append_arg, Fdbus_method_return_internal):
18573 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18574 arguments, check that Lisp number is nonnegative, rather than
18575 silently wrapping negative numbers around. (Bug#8722)
18576 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18579 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18581 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18583 ccl: Add integer overflow checks.
18584 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18585 (IN_INT_RANGE): New macros.
18586 (ccl_driver): Use them to check for integer overflow when
18587 decoding a CCL program. Many of the new checks are whether XINT (x)
18588 fits in int; it doesn't always, on 64-bit hosts. The new version
18589 doesn't catch all possible integer overflows, but it's an
18590 improvement. (Bug#8719)
18592 * alloc.c (make_event_array): Use XINT, not XUINT.
18593 There's no need for unsigned here.
18595 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18596 This follows up to the 2011-05-06 change that substituted uintptr_t
18597 for EMACS_INT. This case wasn't caught back then.
18599 Rework Fformat to avoid integer overflow issues.
18600 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18601 now (part of C89). Include <verify.h>.
18602 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18603 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18604 (Fformat): Avoid the prepass trying to compute sizes; it was only
18605 approximate and thus did not catch overflow reliably. Instead, walk
18606 through the format just once, formatting and computing sizes as we go,
18607 checking for integer overflow at every step, and allocating a larger
18608 buffer as needed. Keep track separately whether the format is
18609 multibyte. Keep only the most-recently calculated precision, rather
18610 than them all. Record whether each argument has been converted to
18611 string. Use EMACS_INT, not int, for byte and char and arg counts.
18612 Support field widths and precisions larger than INT_MAX. Avoid
18613 sprintf's undefined behavior with conversion specifications such as %#d
18614 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18615 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18616 formatting out-of-range floating point numbers with int
18617 formats. (Bug#8668)
18619 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18621 * data.c: Avoid integer truncation in expressions involving floats.
18622 * data.c: Include <intprops.h>.
18623 (arith_driver): When there's an integer overflow in an expression
18624 involving floating point, convert the integers to floating point
18625 so that the resulting value does not suffer from catastrophic
18626 integer truncation. For example, on a 64-bit host (* 4
18627 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18628 Do not rely on undefined behavior after integer overflow.
18630 merge count_size_as_multibyte, parse_str_to_multibyte
18631 * character.c, character.h (count_size_as_multibyte):
18632 Rename from parse_str_to_multibyte; all uses changed.
18633 Check for integer overflow.
18634 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18635 since it's now a duplicate of the other. This is more of
18636 a character than a buffer op, so better that it's in character.c.
18637 * fns.c, print.c: Adjust to above changes.
18639 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18641 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18643 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18645 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18646 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18647 (x_clipboard_manager_save): Now static.
18648 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18650 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18651 (crypto_hash_function): Now static.
18652 Fix pointer signedness problems. Avoid unnecessary initializations.
18654 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18656 * termhooks.h (Vselection_alist): Make it terminal-local.
18658 * terminal.c (create_terminal): Initialize it.
18660 * xselect.c: Support for clipboard managers.
18661 (Vselection_alist): Move to termhooks.h as terminal-local var.
18662 (LOCAL_SELECTION): New macro.
18663 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18664 (symbol_to_x_atom): Remove gratuitous arg.
18665 (x_handle_selection_request, lisp_data_to_selection_data)
18666 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18667 (x_own_selection, x_get_local_selection, x_convert_selection):
18668 New arg, specifying work frame. Use terminal-local Vselection_alist.
18669 (some_frame_on_display): Delete unused function.
18670 (Fx_own_selection_internal, Fx_get_selection_internal)
18671 (Fx_disown_selection_internal, Fx_selection_owner_p)
18672 (Fx_selection_exists_p): New optional frame arg.
18673 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18674 (x_handle_selection_clear): Don't treat other terminals with the
18675 same keyboard specially. Use the terminal-local Vselection_alist.
18676 (x_clear_frame_selections): Use Frun_hook_with_args.
18678 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18680 * xterm.h: Add support for those atoms.
18682 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18684 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18685 (converted_selections, conversion_fail_tag): New global variables.
18686 (x_selection_request_lisp_error): Free the above.
18687 (x_get_local_selection): Remove unnecessary code.
18688 (x_reply_selection_request): Args changed; handle arbitrary array
18689 of converted selections stored in converted_selections.
18690 Separate the XChangeProperty and SelectionNotify steps.
18691 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18692 (x_convert_selection): New function.
18693 (x_handle_selection_event): Simplify.
18694 (x_get_foreign_selection): Don't ignore incoming requests while
18695 waiting for an answer; this will fail when we implement
18696 SAVE_TARGETS, and seems unnecessary anyway.
18697 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18698 (Vx_sent_selection_functions): Doc fix.
18700 2011-05-26 Leo Liu <sdl.web@gmail.com>
18702 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18704 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18706 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18708 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18709 for fringe update if it has periodic bitmap.
18710 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18711 and fringe_bitmap_periodic_p.
18713 * fringe.c (get_fringe_bitmap_data): New function.
18714 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18715 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18716 row. Mark glyph row for fringe update if periodicity changed.
18718 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18719 for fringe update unless it has periodic bitmap.
18721 2011-05-25 Kenichi Handa <handa@m17n.org>
18723 * xdisp.c (get_next_display_element): Set correct it->face_id for
18724 a static composition.
18726 2011-05-24 Leo Liu <sdl.web@gmail.com>
18729 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18731 * fns.c (crypto_hash_function, Fsha1): New function.
18732 (Fmd5): Use crypto_hash_function.
18733 (syms_of_fns): Add Ssha1.
18735 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18737 * gnutls.c: Remove unused macros.
18738 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18739 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18740 Remove macros that are defined and never used.
18741 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18743 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18745 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18746 (Fx_get_selection_internal): Minor cleanup.
18747 (Fx_own_selection_internal): Rename arguments for consistency with
18750 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18752 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18754 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18756 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18758 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18760 * dispnew.c (scrolling_window): Don't exclude the case that the
18761 last enabled row in the desired matrix touches the bottom boundary.
18763 2011-05-21 Glenn Morris <rgm@gnu.org>
18765 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18766 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18767 and add some more files.
18769 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18771 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18772 report_file_error introduced by the change from 2011-05-07.
18774 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18776 * systime.h (Time): Define only if emacs is defined.
18777 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18778 where the include path doesn't have X11/X.h by default. See
18779 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18781 2011-05-20 Kenichi Handa <handa@m17n.org>
18783 * composite.c (find_automatic_composition): Fix previous change.
18785 2011-05-20 Glenn Morris <rgm@gnu.org>
18787 * lisp.mk: New file, split from Makefile.in.
18788 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18789 (shortlisp): Remove.
18790 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18792 2011-05-19 Glenn Morris <rgm@gnu.org>
18794 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18795 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18796 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18797 (lisp): Set the order to that of loadup.el.
18798 (shortlisp): Make it a copy of $lisp.
18799 (SOME_MACHINE_LISP): Remove.
18800 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18801 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18803 2011-05-18 Kenichi Handa <handa@m17n.org>
18805 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18806 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18807 (find_automatic_composition): Mostly rewrite for efficiency.
18809 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18811 * makefile.w32-in: Update dependencies.
18813 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18815 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18816 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18818 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18820 Fix some integer overflow issues, such as string length overflow.
18822 * insdel.c (count_size_as_multibyte): Check for string overflow.
18824 * character.c (lisp_string_width): Check for string overflow.
18825 Use EMACS_INT, not int, for string indexes and lengths; in
18826 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18827 the resulting string length overflows an EMACS_INT; instead,
18828 report a string overflow if no precision given. When checking for
18829 precision exhaustion, use a check that cannot possibly have
18830 integer overflow. (Bug#8675)
18831 * character.h (lisp_string_width): Adjust to new signature.
18833 * alloc.c (string_overflow): New function.
18834 (Fmake_string): Use it. This doesn't change behavior, but saves
18835 a few bytes and will simplify future changes.
18836 * character.c (string_escape_byte8): Likewise.
18837 * lisp.h (string_overflow): New decl.
18839 Fixups, following up to the user-interface timestamp change.
18840 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18841 for UI timestamps, instead of unsigned long.
18842 * msdos.c (mouse_get_pos): Likewise.
18843 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18844 * w32gui.h (Time): Define by including "systime.h" rather than by
18845 declaring it ourselves. (Bug#8664)
18847 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18848 * image.c (clear_image_cache): Likewise.
18850 * term.c (term_mouse_position): Don't assume time_t wraparound.
18852 Be more systematic about user-interface timestamps.
18853 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18854 and sometimes 'EMACS_UINT', to represent these timestamps.
18855 This change causes it to use 'Time' uniformly, as that's what X uses.
18856 This makes the code easier to follow, and makes it easier to catch
18857 integer overflow bugs such as Bug#8664.
18858 * frame.c (Fmouse_position, Fmouse_pixel_position):
18859 Use Time, not unsigned long, for user-interface timestamps.
18860 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18861 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18862 * keyboard.h (last_event_timestamp): Likewise.
18863 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18864 * menu.h (xmenu_show): Likewise.
18865 * term.c (term_mouse_position): Likewise.
18866 * termhooks.h (struct input_event.timestamp): Likewise.
18867 (struct terminal.mouse_position_hook): Likewise.
18868 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18869 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18870 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18871 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18872 what it was before.
18873 * menu.h, termhooks.h: Include "systime.h", for Time.
18875 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18876 Don't assume that the difference between two unsigned long values
18877 can fit into an integer. At this point, we know button_down_time
18878 <= event->timestamp, so the difference must be nonnegative, so
18879 there's no need to cast the result if double-click-time is
18880 nonnegative, as it should be; check that it's nonnegative, just in
18881 case. This bug is triggered when events are more than 2**31 ms
18882 apart (about 25 days). (Bug#8664)
18884 * xselect.c (last_event_timestamp): Remove duplicate decl.
18885 (x_own_selection): Remove needless cast to unsigned long.
18887 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18888 that always fit in int. Use a sentinel instead of a counter, to
18889 avoid a temp and to allay GCC's concerns about possible int overflow.
18890 * frame.h (struct frame): Use int for menu_bar_items_used
18891 instead of EMACS_INT, since it always fits in int.
18893 * menu.c (grow_menu_items): Check for int overflow.
18895 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18897 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18898 Before, the code was not consistent. These values cannot exceed
18899 2**31 - 1 so there's no need to make them unsigned.
18900 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18901 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18902 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18904 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18906 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18907 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18908 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18909 presumably because the widths might not match.
18911 * window.c (size_window): Avoid needless test at loop start.
18913 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18915 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18917 2011-05-12 Drew Adams <drew.adams@oracle.com>
18919 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18921 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18923 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18924 `width' to `bar_area_x' and `bar_area_width', respectively.
18925 (x_scroll_run): Take account of fringe background extension.
18927 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18928 Rename local vars `left' and `width' to `bar_area_x' and
18929 `bar_area_width', respectively.
18930 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18931 background extension.
18933 2011-05-10 Jim Meyering <meyering@redhat.com>
18935 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18937 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18939 * image.c (Finit_image_library): Return t for built-in image types,
18940 like pbm and xbm. (Bug#8640)
18942 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18944 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18946 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18948 * w32console.c (Fset_screen_color): Doc fix.
18949 (Fget_screen_color): New function.
18950 (syms_of_ntterm): Defsubr it.
18952 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18953 unlink the temporary file if Fcall_process didn't create it in the
18955 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18956 child process will be redirected to a file specified with `:file'.
18957 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18958 cue to call_process_cleanup not to close that handle.
18960 2011-05-07 Ben Key <bkey76@gmail.com>
18962 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18963 one of two shell specific rules, either bootstrap-temacs-CMD or
18964 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18965 to the previous implementation of the bootstrap-temacs rule.
18966 The bootstrap-temacs-CMD rule is similar to the previous
18967 implementation of the bootstrap-temacs rule except that it
18968 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18971 These changes, along with some changes to nt/configure.bat,
18972 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18973 earlier fix to add support for --cflags and --ldflags options
18974 that include quotes so that it works whether make uses cmd or
18977 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18979 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18980 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18982 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18983 a string. Handle both cases.
18984 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18985 (Fdbus_register_method): Use Qinvalid_function.
18987 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18989 * makefile.w32-in: Update dependencies.
18990 (LISP_H): Add inttypes.h and stdin.h.
18991 (PROCESS_H): Add unistd.h.
18993 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18995 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18996 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18998 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19000 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19002 * term.c (vfatal): Remove stray call to va_end.
19003 It's not needed and the C Standard doesn't allow it here anyway.
19005 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19006 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19008 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19011 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19013 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19015 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19017 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19019 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19021 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19022 * charset.c (Fdefine_charset_internal): Don't initialize
19023 charset.code_space[15]. The value was garbage, on hosts with
19024 32-bit int (Bug#8600).
19026 * lread.c (read_integer): Be more consistent with string-to-number.
19027 Use string_to_number to do the actual conversion; this avoids
19028 rounding errors and fixes some other screwups. Without this fix,
19029 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19030 (digit_to_number): Move earlier, for benefit of read_integer.
19031 Return -1 if the digit is out of range for the base, -2 if it is
19032 not a digit in any supported base. (Bug#8602)
19034 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19036 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19037 to match comment at start of function. This also removes a
19038 GCC warning about overflow in a 32+64-bit port.
19040 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19042 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19043 Reported by Stefan Monnier in
19044 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19045 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19046 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19048 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19049 (EMACS_UINTPTR): Likewise, with uintptr_t.
19051 * lisp.h: Prefer 64-bit EMACS_INT if available.
19052 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19053 on 32-bit hosts that have 64-bit int, so that they can access
19055 However, temporarily disable this change unless the temporary
19056 symbol WIDE_EMACS_INT is defined.
19058 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19060 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19061 This removes an assumption that EMACS_INT and long are the same
19062 width as pointers. The assumption is true for Emacs porting targets
19063 now, but we want to make other targets possible.
19064 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19065 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19066 In the rest of the code, change types of integers that hold casted
19067 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19068 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19069 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19070 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19071 No need to cast type when ORing.
19072 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19073 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19074 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19075 assume EMACS_INT is the same width as char *.
19076 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19077 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19078 Remove no-longer-needed casts.
19079 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19080 (xg_tool_bar_help_callback, xg_make_tool_item):
19081 Use EMACS_INTPTR to hold an integer
19082 that will be cast to void *; this can avoid a GCC warning
19083 if EMACS_INT is not the same width as void *.
19084 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19085 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19086 (current_message_1, set_message_1):
19087 Use a local to convert to proper width without a cast.
19088 * xmenu.c (dialog_selection_callback): Likewise.
19090 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19091 Also, don't assume VALBITS / RAND_BITS is less than 5,
19092 and don't rely on undefined behavior when shifting a 1 left into
19094 * lisp.h (get_random): Change signature to match.
19096 * lread.c (hash_string): Use size_t, not int, for hash computation.
19097 Normally we prefer signed values; but hashing is special, because
19098 it's better to use unsigned division on hash table sizes so that
19099 the remainder is nonnegative. Also, size_t is the natural width
19100 for hashing into memory. The previous code used 'int', which doesn't
19101 retain enough info to hash well into very large tables.
19102 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19104 * dbusbind.c: Don't possibly lose pointer info when converting.
19105 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19106 Use XPNTR rather than XHASH, so that the high-order bits of
19107 the pointer aren't lost when converting through void *.
19109 * eval.c (Fautoload): Don't double-shift a pointer.
19111 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

19194 * process.c: Include lisp.h before w32.h, not after.
19195 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19196 instead of gnutls_record_check_pending.
19198 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19200 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19202 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19203 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19206 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19208 * xterm.c (x_set_frame_alpha): Do not set property on anything

19248 rather than `XVECTOR (FOO)->size'.
19250 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19251 inttypes.h, as a gnulib replacement is used if it not available in
19254 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19256 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

19266 charbuf for the composition carryover bytes.
19268 2011-04-21 Eli Zaretskii <eliz@gnu.org>

19273 %llo or %llx format is passed. (Bug#8545)
19275 * window.c (window_scroll_line_based): Use a marker instead of
19276 simple variables to record original value of point. (Bug#7952)

19279 produced by %s or %c overflows available buffer space. (Bug#8545)
19281 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19283 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19286 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19288 * w32.c (init_environment): Warn about defaulting HOME to C:\.

19292 * keyboard.c (Qdelayed_warnings_hook): Define.
19293 (command_loop_1): Run `delayed-warnings-hook'
19294 if Vdelayed_warnings_list is non-nil.
19295 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19296 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19298 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19300 * doprnt.c (doprnt): Don't return value smaller than the buffer
19301 size if the message was truncated. (Bug#8545).
19303 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19305 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19306 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19308 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19310 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19312 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19314 * makefile.w32-in: Update dependencies.
19316 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19318 Improve `doprnt' and its usage. (Bug#8545)
19319 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19320 `format_end'. Remove support for %l as a conversion specifier.
19321 Don't use xrealloc. Improve diagnostics when the %l size modifier
19322 is used. Update the commentary.
19324 * eval.c (verror): Simplify calculation of size_t.
19326 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19329 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19331 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19334 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19336 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19337 This makes this file independent of the recent pseudovector change.
19339 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19341 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19343 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19344 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19345 Remove unused local.
19346 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19348 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19349 GCC 4.6.0 optimizes based on type-based alias analysis.
19350 For example, if b is of type struct buffer * and v of type struct
19351 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19352 != &v->size, and therefore "v->size = 1; b->size = 2; return
19353 v->size;" must therefore return 1. This assumption is incorrect
19354 for Emacs, since it type-puns struct Lisp_Vector * with many other
19355 types. To fix this problem, this patch adds a new type struct
19356 vectorlike_header that documents the constraints on layout of vectors
19357 and pseudovectors, and helps optimizing compilers not get fooled
19358 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19359 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19360 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19362 (XSETPVECTYPE): Rewrite in terms of new macro.
19363 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19364 This is a bit clearer, and further avoids the possibility of
19365 undesirable aliasing.
19366 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19367 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19368 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19369 since Lisp_Subr is a special case (no "next" field).
19370 (ASIZE): Now uses header.size rather than size.
19371 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19372 to avoid the hassle of writing XVECTOR (foo)->header.size.
19373 (struct vectorlike_header): New type.
19374 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19375 object, to help avoid aliasing.
19376 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19377 (SUBRP): Likewise, since Lisp_Subr is a special case.
19378 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19379 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19380 (struct Lisp_Hash_Table): Combine first two members into a single
19381 struct vectorlike_header member. All uses of "size" and "next" members
19382 changed to be "header.size" and "header.next".
19383 * buffer.h (struct buffer): Likewise.
19384 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19385 * frame.h (struct frame): Likewise.
19386 * process.h (struct Lisp_Process): Likewise.
19387 * termhooks.h (struct terminal): Likewise.
19388 * window.c (struct save_window_data, struct saved_window): Likewise.
19389 * window.h (struct window): Likewise.
19390 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19391 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19392 * buffer.c (init_buffer_once): Likewise.
19393 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19395 * process.c (Fformat_network_address): Use local var for size,
19398 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19400 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19401 * data.c (atof): Remove decl; no longer used or needed.
19402 (digit_to_number): Move to lread.c.
19403 (Fstring_to_number): Use new string_to_number function, to be
19404 consistent with how the Lisp reader treats infinities and NaNs.
19405 Do not assume that floating-point numbers represent EMACS_INT
19406 without losing information; this is not true on most 64-bit hosts.
19407 Avoid double-rounding errors, by insisting on integers when
19408 parsing non-base-10 numbers, as the documentation specifies.
19409 * lisp.h (string_to_number): New decl, replacing ...
19410 (isfloat_string): Remove.
19411 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19412 (read1): Do not accept +. and -. as integers; this
19413 appears to have been a coding error. Similarly, do not accept
19414 strings like +-1e0 as floating point numbers. Do not report
19415 overflow for integer overflows unless the base is not 10 which
19416 means we have no simple and reliable way to continue.
19417 Break out the floating-point parsing into a new
19418 function string_to_number, so that Fstring_to_number parses
19419 floating point numbers consistently with the Lisp reader.
19420 (digit_to_number): Move here from data.c. Make it static inline.
19421 (E_CHAR, EXP_INT): Remove, replacing with ...
19422 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19423 (string_to_number): New function, replacing isfloat_string.
19424 This function checks for valid syntax and produces the resulting
19425 Lisp float number too. Rework it so that string-to-number
19426 no longer mishandles examples like "1.0e+". Use strtoumax,
19427 so that overflow for non-base-10 numbers is reported only when
19428 there's no portable and simple way to convert to floating point.
19430 * textprop.c (set_text_properties_1): Rewrite for clarity,
19431 and to avoid GCC warning about integer overflow.
19433 * intervals.h (struct interval): Use EMACS_INT for members
19434 where EMACS_UINT might cause problems. See
19435 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19436 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19437 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19439 (offset_intervals): Tell GCC not to worry about length overflow
19440 when negating a negative length.
19442 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19443 (overrun_check_free): Likewise.
19445 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19446 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19449 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19450 (gnutls_make_error): Rename local to avoid shadowing.
19451 (gnutls_emacs_global_deinit): ifdef out; not used.
19452 (Fgnutls_boot): Use const for pointer to readonly storage.
19453 Comment out unused local. Fix pointer signedness problems.
19455 * lread.c (openp): Don't stuff size_t into an 'int'.
19456 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19457 about possible signed overflow.
19459 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19460 (GDK_KEY_g): Don't define if already defined.
19461 (xg_prepare_tooltip): Avoid pointer signedness problem.
19462 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19464 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19465 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19467 * xfns.c (Fx_window_property): Simplify a bit,
19468 to make a bit faster and to avoid GCC 4.6.0 warning.
19469 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19471 * fns.c (internal_equal): Don't assume size_t fits in int.
19473 * alloc.c (compact_small_strings): Tighten assertion a little.
19475 Replace pEd with more-general pI, and fix some printf arg casts.
19476 * lisp.h (pI): New macro, generalizing old pEd macro to other
19477 conversion specifiers. For example, use "...%"pI"d..." rather
19478 than "...%"pEd"...".
19479 (pEd): Remove. All uses replaced with similar uses of pI.
19480 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19481 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19482 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19483 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19484 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19485 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19486 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19488 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19489 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19490 * print.c (safe_debug_print, print_object): Likewise.
19491 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19493 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19494 avoiding the 0 flag, which is not portable.
19495 * process.c (Fmake_network_process): Use pI to avoid cast.
19496 * region-cache.c (pp_cache): Likewise.
19497 * xdisp.c (decode_mode_spec): Likewise.
19498 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19499 behavior on 64-bit hosts with printf arg.
19500 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19501 (x_stop_queuing_selection_requests): Likewise.
19502 (x_get_window_property): Don't truncate byte count to an 'int'
19505 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19506 here, since it parses constructs like leading '-' and spaces,
19507 which are not wanted; and it overflows with large numbers.
19508 Instead, simply match F[0-9]+, which is what is wanted anyway.
19510 * alloc.c: Remove unportable assumptions about struct layout.
19511 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19512 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19513 (allocate_vectorlike, make_pure_vector): Use the new macros,
19514 plus offsetof, to remove unportable assumptions about struct layout.
19515 These assumptions hold on all porting targets that I know of, but

20409 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20411 Fix more problems found by GCC 4.6.0's static checks.
20413 * xdisp.c (vmessage): Use a better test for character truncation.
20415 * charset.c (load_charset_map): <, not <=, for optimization,
20416 and to avoid potential problems with integer overflow.
20417 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20418 * casetab.c (set_identity, shuffle): Likewise.
20419 * editfns.c (Fformat): Likewise.
20420 * syntax.c (skip_chars): Likewise.
20422 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20423 This also lets GCC 4.6.0 generate slightly better loop code.
20425 * callint.c (Fcall_interactively): <, not <=, for optimization.
20426 (Fcall_interactively): Count the number of arguments produced,
20427 not the number of arguments given. This is simpler and lets GCC
20428 4.6.0 generate slightly better code.
20430 * ftfont.c: Distingish more carefully between FcChar8 and char.
20431 The previous code passed unsigned char * to a functions like
20432 strlen and xstrcasecmp that expect char *, which does not
20433 conform to the C standard.
20434 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20435 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20436 char * when the C standard requires it.
20438 * keyboard.c (read_char): Remove unused var.
20440 * eval.c: Port to Windows vsnprintf (Bug#8435).
20441 Include <limits.h>.
20442 (SIZE_MAX): Define if the headers do not.
20443 (verror): Do not give up if vsnprintf returns a negative count.
20444 Instead, grow the buffer. This ports to Windows vsnprintf, which
20445 does not conform to C99. Problem reported by Eli Zaretskii.
20446 Also, simplify the allocation scheme, by avoiding the need for
20447 calling realloc, and removing the ALLOCATED variable.
20449 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20451 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20452 But keep the doprint source code for now, as we might revamp it
20453 and use it again (Bug#8435).
20454 * lisp.h (doprnt): Remove.
20455 * Makefile.in (base_obj): Remove doprnt.o.
20456 * deps.mk (doprnt.o): Remove.
20458 error: Print 32- and 64-bit integers portably (Bug#8435).
20459 Without this change, on typical 64-bit hosts error ("...%d...", N)
20460 was used to print both 32- and 64-bit integers N, which relied on
20461 undefined behavior.
20462 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20463 * lisp.h (error, verror): Mark as printf-like functions.
20464 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20465 Report overflow in size calculations when allocating printf buffer.
20466 Do not truncate output string at its first null byte.
20467 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20468 Truncate the output at a character boundary, since vsnprintf does not
20470 * charset.c (check_iso_charset_parameter): Convert internal
20471 character to string before calling 'error', since %c now has the
20473 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20474 overflow when computing char to be passed to 'error'. Do not
20475 pass Lisp_Object to 'error'; pass the integer instead.
20476 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20477 formatted with plain %d.
20479 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20481 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20483 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20485 * xterm.c (x_catch_errors): Remove duplicate declaration.
20487 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20489 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20491 2011-04-10 Jim Meyering <meyering@redhat.com>
20493 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20494 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20495 return ssize_t not "int", and use size_t as the buffer length.
20496 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20497 * gnutls.h: Update declarations.
20498 * process.c (read_process_output): Use ssize_t, to match.
20499 (send_process): Likewise.
20501 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20503 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20505 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20507 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20508 Use unsigned char, to match FcChar8 type definition.
20510 * xterm.c (handle_one_xevent):
20511 * xmenu.c (create_and_show_popup_menu):
20512 * xselect.c (x_decline_selection_request)
20513 (x_reply_selection_request): Avoid type-punned deref of X events.
20515 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20517 Fix some uses of `int' instead of EMACS_INT.
20518 * search.c (string_match_1, fast_string_match)
20519 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20520 (scan_buffer, find_next_newline_no_quit)
20521 (find_before_next_newline, search_command, Freplace_match)
20522 (Fmatch_data): Make some `int' variables be EMACS_INT.
20524 * xdisp.c (display_count_lines): 3rd argument and return value now
20525 EMACS_INT. All callers changed.
20526 (pint2hrstr): Last argument is now EMACS_INT.
20528 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20529 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20530 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20531 (decode_coding_utf_16, decode_coding_emacs_mule)
20532 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20533 (decode_coding_ccl, decode_coding_charset)
20534 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20535 (decode_coding_iso_2022, decode_coding_emacs_mule)
20536 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20537 <char_offset, last_offset>: Declare EMACS_INT.
20538 (encode_coding_utf_8, encode_coding_utf_16)
20539 (encode_coding_emacs_mule, encode_invocation_designation)
20540 (encode_designation_at_bol, encode_coding_iso_2022)
20541 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20542 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20544 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20545 (encode_invocation_designation): Last argument P_NCHARS is now
20547 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20548 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20550 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20553 * ccl.c (Fccl_execute_on_string): Declare some variables
20556 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20558 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20560 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20562 * process.c (Fformat_network_address): Doc fix.
20564 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20566 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20568 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20570 * keyboard.c (read_char): Call Lisp function help-form-show,
20571 instead of using internal_with_output_to_temp_buffer.
20572 (Qhelp_form_show): New var.
20573 (syms_of_keyboard): Use DEFSYM macro.
20575 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20577 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20579 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20581 * process.c (Flist_processes): Remove to Lisp.
20582 (list_processes_1): Delete.
20584 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20586 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20588 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20590 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20592 Fix more problems found by GCC 4.6.0's static checks.
20594 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20596 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20598 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20600 * xdisp.c (vmessage): Mark as a printf-like function.
20602 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20604 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20606 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20607 printf-like functions.
20608 (tiff_load): Add casts to remove these marks before passing them
20609 to system-supplied API.
20611 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20613 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20614 This avoids several warnings with gcc -Wstrict-overflow.
20615 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20616 directly, rather than having caller test rule sign. This avoids
20617 some unnecessary tests.
20618 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20619 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20620 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20622 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20623 (xfont_open): Avoid unnecessary tests.
20625 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20627 * composite.h, composite.c (composition_gstring_put_cache):
20628 Use EMACS_INT, not int, for length.
20630 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20631 breaking out part of COMPOSITION_DECODE_RULE.
20632 (COMPOSITION_DECODE_RULE): Use it.
20633 * composite.c (get_composition_id): Remove unused local vars,
20634 by using the new macro.
20636 * textprop.c (set_text_properties_1): Change while to do-while,
20637 since the condition is always true at first.
20639 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20640 (interval_deletion_adjustment): Return unsigned value.
20643 * process.c (list_processes_1, create_pty, read_process_output):
20644 (exec_sentinel): Remove vars that were set but not used.
20645 (create_pty): Remove unnecessary "volatile"s.
20646 (Fnetwork_interface_info): Avoid possibility of int overflow.

20648 (read_process_output): Simplify nbytes computation if buffered.
20650 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
20652 * syntax.c (scan_words): Remove var that was set but not used.
20653 (update_syntax_table): Use unsigned instead of int.
20655 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20656 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20657 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20659 * print.c (print_error_message): Avoid int overflow.
20661 * font.c (font_list_entities): Redo for clarity,
20662 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20664 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20665 (font_score): Avoid potential overflow in diff calculation.
20667 * fns.c (substring_both): Remove var that is set but not used.
20668 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20670 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20672 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20673 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20674 can always succeed if overflow has undefined behavior.
20676 * search.c (boyer_moore, wordify): Remove vars set but not used.
20677 (wordify): Omit three unnecessary tests.
20679 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20680 All callers changed. This avoids the need for an unused var.
20682 * casefiddle.c (casify_region): Remove var that is set but not used.
20684 * dired.c (file_name_completion): Remove var that is set but not used.
20686 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20688 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20689 (Finsert_file_contents): Remove unnecessary code checking fd.
20691 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20692 Check for integer overflow on size calculations.
20694 * buffer.c (Fprevious_overlay_change): Remove var that is set
20697 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20698 Remove vars that are set but not used.
20699 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20700 (timer_check_2): Mark vars as initialized.
20702 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20704 * image.c (lookup_image): Remove var that is set but not used.
20705 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20707 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20708 that are set but not used.
20710 * xfns.c (make_invisible_cursor): Don't return garbage
20711 if XCreateBitmapFromData fails (Bug#8410).
20713 * xselect.c (x_get_local_selection, x_handle_property_notify):
20714 Remove vars that are set but not used.
20716 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20717 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20719 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20720 Remove var that is set but not used.
20721 (scroll_bar_windows_size): Now size_t, not int.
20722 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20723 Check for overflow.
20725 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20726 (map_tty_color) [!defined MSDOS]: Likewise.
20728 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20730 * coding.c: Remove vars that are set but not used.
20731 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20732 All callers changed.
20733 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20734 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20735 (decode_coding_charset): Remove vars that are set but not used.
20737 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20738 that is set but not used.
20740 * print.c (print_object): Remove var that is set but not used.
20742 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20743 The gnulib version avoids calling malloc in the usual case,
20744 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20745 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20746 * filelock.c (current_lock_owner): Likewise.
20747 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20748 * sysdep.c: Include allocator.h, careadlinkat.h.
20749 (emacs_no_realloc_allocator): New static constant.
20750 (emacs_readlink): New function.
20751 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20752 ../lib/careadlinkat.h.
20754 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20756 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20757 first non-nil return value).
20759 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20761 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20762 if not defined (Bug#8403).
20764 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20766 * xdisp.c (display_count_lines): Remove parameter `start',
20767 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20768 (get_char_face_and_encoding): Remove parameter `multibyte_p',
20769 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20770 (fill_stretch_glyph_string): Remove parameters `row' and `area',
20771 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20772 and thereabouts. All callers changed.
20773 (get_per_char_metric): Remove parameter `f', unused since
20774 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20776 2011-04-02 Jim Meyering <meyering@redhat.com>
20778 do not dereference NULL upon failed strdup
20779 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20780 (ns_get_family): Likewise.
20782 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20784 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20786 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20788 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20791 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20793 Add lexical binding.
20795 * window.c (Ftemp_output_buffer_show): New fun.
20796 (Fsave_window_excursion):
20797 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20799 * lread.c (lisp_file_lexically_bound_p): New function.
20800 (Fload): Bind Qlexical_binding.
20801 (readevalloop): Remove `evalfun' arg.
20802 Bind Qinternal_interpreter_environment.
20803 (Feval_buffer): Bind Qlexical_binding.
20804 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20806 (syms_of_lread): Declare `lexical-binding'.
20808 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20810 * keyboard.c (eval_dyn): New fun.
20811 (menu_item_eval_property): Use it.
20813 * image.c (parse_image_spec): Use Ffunctionp.
20815 * fns.c (concat, mapcar1): Accept byte-code-functions.
20817 * eval.c (Fsetq): Handle lexical vars.
20818 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20819 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20820 (FletX, Flet): Obey lexical binding.
20821 (Fcommandp): Handle closures.
20822 (Feval): New `lexical' arg.
20823 (eval_sub): New function extracted from Feval. Use it almost
20824 everywhere where Feval was used. Look up vars in lexical env.
20826 (Ffunctionp): Move from subr.el.
20827 (Ffuncall): Handle closures.
20828 (apply_lambda): Remove `eval_flags'.
20829 (funcall_lambda): Handle closures and new byte-code-functions.
20830 (Fspecial_variable_p): New function.
20831 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20832 but without exporting it to Lisp.
20834 * doc.c (Fdocumentation, store_function_docstring):
20835 * data.c (Finteractive_form): Handle closures.
20837 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20840 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20842 (exec_byte_code): New function extracted from Fbyte_code to handle new
20843 calling convention for byte-code-functions. Add new byte-codes.
20845 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20847 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20849 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20851 * xdisp.c (redisplay_internal): Fix prototype.
20853 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20855 * xdisp.c (SCROLL_LIMIT): New macro.
20856 (try_scrolling): Use it when setting scroll_limit.
20857 Limit scrolling to 100 screen lines.
20858 (redisplay_window): Even when falling back on "recentering",
20859 position point in the window according to scroll-conservatively,
20860 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20862 (try_scrolling): When point is above the window, allow searching
20863 as far as scroll_max, or one screenful, to compute vertical
20864 distance from PT to the scroll margin position. This prevents
20865 try_scrolling from unnecessarily failing when
20866 scroll-conservatively is set to a value slightly larger than the
20867 window height. Clean up the case of PT below the margin at bottom
20868 of window: scroll_max can no longer be INT_MAX. When aggressive
20869 scrolling is in use, don't let point enter the opposite scroll
20870 margin as result of the scroll.
20871 (syms_of_xdisp) <scroll-conservatively>: Document the
20872 threshold of 100 lines for never-recentering scrolling.
20874 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20876 * dispextern.h (move_it_by_lines):
20877 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20878 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20879 (message_log_check_duplicate): Remove parameters `prev_bol' and
20880 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20881 (redisplay_internal): Remove parameter `preserve_echo_area',
20882 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20884 * indent.c (Fvertical_motion):
20885 * window.c (window_scroll_pixel_based, Frecenter):
20886 Don't pass `need_y_p' to `move_it_by_lines'.
20888 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20890 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20891 steal a few bits to be more compact.
20892 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20893 Remove unneeded casts.
20895 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20897 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20899 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20900 binding" message (bug#7967).
20902 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20904 Fix more problems found by GCC 4.6.0's static checks.
20906 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20907 Remove unused local var.
20909 * editfns.c (Fmessage_box): Remove unused local var.
20911 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20912 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20913 Omit unused local vars.
20914 * window.c (shrink_windows): Omit unused local var.
20915 * menu.c (digest_single_submenu): Omit unused local var.
20916 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20917 Omit unused local var.
20919 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20920 Don't assume string length fits in int.
20921 (keyremap_step, read_key_sequence): Use size_t for sizes.
20922 (read_key_sequence): Don't check last_real_key_start redundantly.
20924 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20925 instead of alloca (Bug#8344).
20927 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20928 (Fbacktrace_frame): Don't assume nframes fits in int.
20930 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20932 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20935 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20937 * cm.c (calccost): Turn while-do into do-while, for clarity.
20939 * keyboard.c (syms_of_keyboard): Use the same style as later
20940 in this function when indexing through an array. This also
20941 works around GCC bug 48267.
20943 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20945 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

20948 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20950 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20951 This avoids undefined behavior on integer overflow, and is a bit
20952 more convenient anyway since it is compared to a size_t variable.
20954 Variadic C functions now count arguments with size_t, not int.
20955 This avoids an unnecessary limitation on 64-bit machines, which
20956 caused (substring ...) to crash on large vectors (Bug#8344).
20957 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

20964 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20965 (funcall_lambda, mark_backtrace): Likewise.
20966 * fns.c (concat): Likewise.
20967 * frame.c (x_set_frame_parameters): Likewise.
20968 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20969 0 if not found, not -1. All callers changed.
20971 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20972 (stack_copy_size): Now size_t, not int.
20973 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

20977 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20978 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20981 * lisp.h (multibyte_char_to_unibyte):
20982 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20983 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20984 * character.h (CHAR_TO_BYTE8):
20985 * cmds.c (internal_self_insert):
20986 * editfns.c (general_insert_function):
20987 * keymap.c (push_key_description):
20988 * search.c (Freplace_match):
20989 * xdisp.c (message_dolog, set_message_1): All callers changed.
20991 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
20993 * keyboard.c (safe_run_hook_funcall): New function.
20994 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20995 don't set the hook to nil, but remove the offending function instead.
20996 (Qcommand_hook_internal): Remove, unused.
20997 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20998 Vcommand_hook_internal.
21000 * eval.c (enum run_hooks_condition): Remove.
21001 (funcall_nil, funcall_not): New functions.
21002 (run_hook_with_args): Call each function through a `funcall' argument.
21003 Remove `cond' argument, now redundant.
21004 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21005 (Frun_hook_with_args_until_failure): Adjust accordingly.
21006 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21008 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21010 * dispextern.h (string_buffer_position): Remove declaration.
21012 * print.c (strout): Remove parameter `multibyte', unused since
21013 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21015 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21016 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21017 All callers changed.
21019 * w32.c (_wsa_errlist): Use braces for struct initializers.
21021 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21022 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21023 All callers changed.
21024 (string_buffer_position): Likewise. Also, make static (it's never
21025 used outside xdisp.c).
21026 (cursor_row_p): Remove parameter `w', unused since
21027 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21029 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21030 All callers changed.
21032 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21034 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21045 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21047 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

21063 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21065 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21067 * w32.c (read_unc_volume): Use parameter `henum', instead of
21068 global variable `wget_enum_handle'.
21070 * keymap.c (describe_vector): Remove parameters `indices' and
21071 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21086 * gtkutil.c (xg_maybe_add_timer):
21087 * keyboard.c (readable_events):
21088 * process.c (wait_reading_process_output):
21089 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21091 * insdel.c (adjust_markers_gap_motion):
21092 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

21166 2011-03-23 Julien Danjou <julien@danjou.info>
21168 * term.c (Fsuspend_tty, Fresume_tty):
21169 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21170 * window.c (temp_output_buffer_show):

21177 * callint.c (Fcall_interactively):
21178 * buffer.c (Fkill_all_local_variables):
21179 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21181 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21182 unconditionally since it does the check itself.
21184 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21186 Fix more problems found by GCC 4.5.2's static checks.
21188 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21189 the first time through the loop, since we know p0 < p1 then.
21190 This also avoids a gcc -Wstrict-overflow warning.
21192 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21193 leading to a memory leak, possible in functions like
21194 load_charset_map_from_file that can allocate an unbounded number
21195 of objects (Bug#8318).
21197 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21198 that could (at least in theory) be that large.
21200 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21201 This is less likely to overflow, and avoids undefined behavior if
21202 overflow does occur. All callers changed. Use strtoul to scan
21203 for the unsigned long integer.
21204 (pint2hrstr): Simplify and tune code slightly.
21205 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21220 * process.c (Fmake_network_process): Use socklen_t, not int,
21221 where POSIX says socklen_t is required in portable programs.
21222 This fixes a porting bug on hosts like 64-bit HP-UX, where
21223 socklen_t is wider than int (Bug#8277).
21224 (Fmake_network_process, server_accept_connection):
21225 (wait_reading_process_output, read_process_output):
21228 * process.c: Rename or move locals to avoid shadowing.

21235 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21236 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21238 Make tparam.h and terminfo.c consistent.
21239 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21240 Include tparam.h instead, since it declares them.
21241 * cm.h (PC): Remove extern decl; tparam.h now does this.
21242 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21243 * terminfo.c: Include tparam.h, to check interfaces.
21244 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21245 (tparam): Adjust signature to match interface in tparam.h;
21246 this removes some undefined behavior. Check that outstring and len
21247 are zero, which they always are with Emacs.
21248 * tparam.h (PC, BC, UP): New extern decls.
21250 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21251 (xftfont_open): Rename locals to avoid shadowing.
21253 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21254 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21255 (OTF_TAG_SYM): Omit macro if not needed.
21256 (ftfont_list): Remove unused local.

21258 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21259 Rename locals to avoid shadowing.
21261 * xfont.c (xfont_list_family): Mark var as initialized.
21263 * xml.c (make_dom): Now static.
21265 * composite.c (composition_compute_stop_pos): Rename local to
21267 (composition_reseat_it): Remove unused locals.
21268 (find_automatic_composition, composition_adjust_point): Likewise.
21269 (composition_update_it): Mark var as initialized.
21270 (find_automatic_composition): Mark vars as initialized,
21271 with a FIXME (Bug#8290).
21273 character.h: Rename locals to avoid shadowing.
21274 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21275 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21276 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21277 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21278 to avoid shadowing.
21280 * textprop.c (property_change_between_p): Remove; unused.
21282 * intervals.c (interval_start_pos): Now static.
21284 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
21286 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
21287 Rename locals to avoid shadowing.
21289 * sound.c (wav_play, au_play, Fplay_sound_internal):
21290 Fix pointer signedness.
21291 (alsa_choose_format): Remove unused local var.
21292 (wav_play): Initialize a variable to 0, to prevent undefined
21293 behavior (Bug#8278).
21295 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21297 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21299 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21300 clobbering (Bug#8298).
21301 * sysdep.c (sys_subshell): Likewise.
21302 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21304 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21305 This should get cleaned up, so that child_setup has the
21306 same signature on all platforms.
21308 * callproc.c (call_process_cleanup): Now static.
21309 (relocate_fd): Rename locals to avoid shadowing.
21311 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

21470 (Fmemory_limit): Cast sbrk's returned value to char *.
21472 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21477 Use functions, not macros, for up- and down-casing (Bug#8254).
21478 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21479 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21480 to use the following functions instead of these macros.
21481 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21482 EMACS_INT, since callers assume the returned value fits in int.
21483 (upcase1): Likewise, for UPCASE_TABLE.
21484 (uppercasep, lowercasep, upcase): New static inline functions.
21485 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21495 (regex_compile, re_match_2_internal): Mark locals as initialized.
21496 (RETALLOC_IF): Define only if needed.
21497 (WORDCHAR_P): Likewise. This one is never needed, but is used
21498 only in a comment talking about a compiler bug, so put inside
21499 the #if 0 of that comment.
21500 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21501 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21527 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21528 New macros, so that the caller can use some names other than
21529 gcpro1, gcpro2, etc.
21530 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21532 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21533 argument, for consistency with GCPRO2_VAR, etc: it is now the
21534 prefix of the variable, not the variable itself. All uses
21536 * dired.c (directory_files_internal, file_name_completion):
21537 Rename locals to avoid shadowing.
21539 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21540 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21541 dired.c's scmp function, had undefined behavior.
21542 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21543 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21544 * buffer.h: ... to here, because these macros use current_buffer,
21545 and the new implementation with inline functions needs to have
21546 current_buffer in scope now, rather than later when the macros
21548 (downcase, upcase1): New static inline functions.
21549 (DOWNCASE, UPCASE1): Reimplement using these functions.
21550 This avoids undefined behavior in expressions like
21551 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21552 from race conditions in accessing the global variables
21553 case_temp1 and case_temp2.
21554 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21555 * lisp.h (case_temp1, case_temp2): Remove their decls.
21556 * character.h (ASCII_CHAR_P): Move from here ...
21557 * lisp.h: ... to here, so that the inline functions mentioned
21558 above can use them.
21560 * dired.c (directory_files_internal_unwind): Now static.
21562 * fileio.c (file_name_as_directory, directory_file_name):

21565 (file_name_as_directory): Use const pointers when appropriate.
21566 (Fexpand_file_name): Likewise. In particular, newdir might
21567 point at constant storage, so make it a const pointer.
21568 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21569 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21571 (Fset_file_times, Finsert_file_contents, auto_save_error):

21576 to avoid shadowing.
21578 * marker.c (bytepos_to_charpos): Remove; unused.
21580 * lisp.h (verify_bytepos, count_markers): New decls,
21581 so that gcc does not warn that these functions aren't declared.
21583 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21584 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21585 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21586 (copy_text): Remove unused local var.
21588 * filelock.c (within_one_second): Now static.
21589 (lock_file_1): Rename local to avoid shadowing.
21591 * buffer.c (fix_overlays_before): Mark locals as initialized.
21592 (fix_start_end_in_overlays): Likewise. This function should be
21593 simplified by using pointers-to-pointers, but that's a different
21595 (switch_to_buffer_1): Now static.
21596 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21597 (report_overlay_modification): Rename locals to avoid shadowing.
21599 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21600 Fix pointer signedness issue.
21601 (sys_subshell): Mark local as volatile if checking for lint,
21602 to suppress a gcc -Wclobbered warning that does not seem to be right.
21603 (MAXPATHLEN): Define only if needed.
21605 * process.c (serial_open, serial_configure): Move decls from here ...
21606 * systty.h: ... to here, so that they can be checked.
21608 * fns.c (get_random, seed_random): Move extern decls from here ...
21609 * lisp.h: ... to here, so that they can be checked.
21611 * sysdep.c (reset_io): Now static.
21612 (wait_for_termination_signal): Remove; unused.
21614 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21617 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21618 (DENSE_TABLE_SIZE): Remove; unused.
21619 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21620 (describe_map_tree):
21621 Rename locals to avoid shadowing.
21623 * keyboard.c: Declare functions static if they are not used elsewhere.

21645 if GCC considers string literals to be constants.
21647 * lisp.h (fatal_error_signal): Add decl, since it's exported.
