13 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
15 * search.c (scan_buffer): Calculate end byte position just once.

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

34 * indent.c (recompute_width_table):
35 * nsselect.m (clean_local_selection_data):
36 * syntax.c (init_syntax_once):
37 * w32unsubscribe.c (uniscribe_shape):
38 * window.c (Fcurrent_window_configuration):
39 * xfaces.c (Fx_family_fonts):
40 * xselect.c (selection_data_to_lisp_data): Use it.
42 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
44 * coding.c (Fdefine_coding_system_internal): Use AREF where
45 argument is known to be a vector.
46 * fns.c (Flocale_info): Likewise for ASET.
47 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
48 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
50 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
52 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
55 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
56 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
57 updateCollectionBehaviour.
59 * nsterm.m (NEW_STYLE_FS): Remove.
60 (ns_last_use_native_fullscreen): New variable.
61 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
62 (x_set_window_size): Do not take title bar and tool bar into account
63 if isFullscreen returns YES.
64 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
65 (check_native_fs): New function.
66 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
67 (ns_term_init): Remove NEW_STYLE_FS.

80 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
81 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
82 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
83 (syms_of_nsterm): Add ns-use-native-fullscreen.
85 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
87 * fileio.c (Qchoose_write_coding_system): Now static.
89 2013-02-04 Eli Zaretskii <eliz@gnu.org>
91 * xdisp.c (window_buffer_changed): region_showing can be negative,
92 which still means region is being displayed.
93 (redisplay_internal): Resurrect code that forced redisplay of the
94 whole window when showing region and the mark has changed. Record
95 the new mark position to allow redisplay optimizations.
96 (display_line): If it->region_beg_charpos is non-zero, set the
97 window's region_showing member to -1. (Bug#13623) (Bug#13626)
99 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
100 not bitfield of 1 bit.
102 2013-02-03 Daniel Colascione <dancol@dancol.org>
104 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
105 daemon mode works on cygw32 when Emacs is installed and not just
108 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
110 Avoid file time stamp bug on MS-Windows (Bug#13149).
111 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
112 as FAT32 doesn't update time stamps when truncating them.
113 Also, check that a file time stamp is not a multiple of 100 ns;
114 this should catch all instances of the problem on MS-Windows,
115 as its native file system resolution is 100 ns or worse, and
116 checking for a non-multiple of 100 ns should impose only a small
117 overhead on systems with ns resolution.
119 2013-02-02 Eli Zaretskii <eliz@gnu.org>
121 Avoid encoding file names on MS-Windows when they need to be run
122 through dostounix_filename.
123 * w32.c (normalize_filename): Accept an additional argument
124 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
125 downcase it even if w32-downcase-file-names is non-nil.
126 (dostounix_filename): Accept an additional argument MULTIBYTE and
127 pass it to normalize_filename.
128 (emacs_root_dir): Adjust.
130 * msdos.h (dostounix_filename): Adjust prototype.
132 * w32.h (dostounix_filename): Adjust prototype.
134 * msdos.c (dostounix_filename): Accept an additional argument and
136 (init_environment): Adjust callers of dostounix_filename.
138 * fileio.c (Ffile_name_directory, file_name_as_directory)
139 (directory_file_name, Fexpand_file_name)
140 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
142 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
144 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
145 variables, as egetenv is case-insensitive for DOS_NT.
147 * dired.c (file_name_completion): Don't call Fdirectory_file_name
148 with an encoded file name.
150 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
151 calls to dostounix_filename.
153 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
155 * unexw32.c (unexec): Adjust call to dostounix_filename.
157 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
159 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
162 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
165 * callproc.c (Fcall_process): Make sure program name in PATH and
166 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
167 is passed to exec/spawnve, which fails unless the file-name
170 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
171 even if w32-quote-process-args is nil.
173 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
175 Fix timestamp bug when write-region appends nothing (Bug#13149).
176 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
177 the file's time stamp doesn't change if Emacs happens to write nothing
178 to the file, and on a buggy file system this could cause Emacs to
179 incorrectly infer that the file system doesn't have the bug.
180 Avoid this problem by inhibiting the inference in this case.
182 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
184 * window.h (struct window): Convert base_line_number, base_line_pos
185 and column_number_displayed members from Lisp_Object to ptrdiff_t.
186 Convert region_showing member from Lisp_Object to bitfield.
187 Remove sequence_number member. Adjust comments.
188 * window.c (sequence_number): Remove.
189 (make_window): Initialize column_number_displayed.
190 * print.c (print_object): Follow the printed representation of
191 frames and print window pointer to distinguish between windows.
192 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
193 * xdisp.c (wset_base_line_number, wset_base_line_pos)
194 (wset_column_number_displayed, wset_region_showing): Remove.
195 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
196 (try_scrolling, try_cursor_movement, redisplay_window)
197 (try_window_reusing_current_matrix, try_window_id, display_line)
198 (display_mode_lines, decode_mode_spec): Adjust users.
199 * .gdbinit (pwinx): Do not print sequence_number.
201 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
203 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
204 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
205 * dired.c: Include <fcntl.h>.
206 (open_directory): New function, which uses open and fdopendir
207 rather than opendir. DOS_NT platforms still use opendir, though.
208 (directory_files_internal, file_name_completion): Use it.
209 (file_attributes): New function, with most of the old Ffile_attributes.
210 (directory_files_internal, Ffile_attributes): Use it.
211 (file_attributes, file_name_completion_stat): First arg is now fd,
212 not dir name. All uses changed. Use fstatat rather than lstat +
214 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
215 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
216 (emacs_readlinkat): New function, with much of the old
217 Ffile_symlink_p, but with an fd argument for speed.
218 It uses readlinkat rather than careadlinkatcwd, so that it
219 need not assume the working directory.
220 (Ffile_symlink_p): Use it.
221 * filelock.c (current_lock_owner): Use emacs_readlinkat
222 rather than emacs_readlink.
223 * lisp.h (emacs_readlinkat): New decl.
224 (READLINK_BUFSIZE, emacs_readlink): Remove.
225 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
226 (emacs_norealloc_allocator, emacs_readlink): Remove.
227 This stuff is moved to fileio.c.
228 * w32.c (fstatat, readlinkat): New functions.
229 (careadlinkat): Don't check that fd == AT_FDCWD.
230 (careadlinkatcwd): Remove; no longer needed.
232 2013-01-31 Glenn Morris <rgm@gnu.org>
234 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
235 (Fwrite_region): Update for new choose_write_coding_system args.
236 Move the last piece of choose_write_coding_system here. (Bug#13522)
237 (syms_of_fileio): Add choose-write-coding-system.
239 2013-01-30 Eli Zaretskii <eliz@gnu.org>
241 * w32.c (sys_open): Zero out the flags for the new file descriptor.
242 (sys_close): Zero out the flags for the file descriptor before
243 closing it. (Bug#13546)
245 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
246 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
247 CharNextExA and CharPrevExA to iterate over file names encoded in
250 * w32.c (w32_get_long_filename, init_environment, readlink):
251 Support file names encoded in DBCS codepages.
252 (readlink): Use the current file-name-coding-system, not the ANSI
253 codepage, to decode and handle targets of symlinks.
255 2013-01-28 Eli Zaretskii <eliz@gnu.org>
257 * w32.c (opendir): Now accepts a 'const char *'.
259 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
261 Remove obsolete redisplay code. See the discussion at
262 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
263 * dispnew.c (preemption_period, preemption_next_check): Remove.
264 (Vredisplay_preemption_period): Likewise.
265 (update_frame, update_single_window, update_window, update_frame_1):
266 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
267 used, following the 2012-06-22 change.
269 2013-01-25 Eli Zaretskii <eliz@gnu.org>
271 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
273 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
275 * font.c (num_fonts): Remove the leftover from old
276 debugging code. Adjust comment style here and there.
277 * insdel.c (insert_1): Remove.
278 * lisp.h (insert_1): Remove prototype.
279 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
281 2013-01-25 Eli Zaretskii <eliz@gnu.org>
283 * w32.c (max_filename_mbslen): New function.
284 (normalize_filename, readdir): Use it to detect locales where ANSI
285 encoding of file names uses a double-byte character set (DBCS).
286 If a DBCS encoding is used, advance by characters using
287 CharNextExA, instead of incrementing a 'char *' pointer. Use
288 _mbslwr instead of _strlwr. (Bug#13515)
290 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
291 request of memory reservation to 1.7GB. (Bug#13065)
293 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
295 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
296 at check_extra_latin label. (Bug#13505)
298 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
300 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
301 Avoid redundant calls to strlen.
303 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
305 Drop async_visible and async_iconified fields of struct frame.
306 This is possible because async input is gone; for details, see
307 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
308 * frame.h (struct frame): Remove async_visible and async_iconified
309 members, convert garbaged to unsigned bitfield. Adjust comments.
310 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
311 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
312 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
313 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
314 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
316 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
317 properly. Likewise for obscured.
319 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
322 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
324 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
326 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
327 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
329 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
331 * xdisp.c (message2, message2_nolog): Remove functions.
332 (message3, message3_nolog): Extract nbytes and multibyteness directly
333 from the string. Change all callers.
334 (message3_nolog): Don't set message_enable_multibyte since set_message
335 will reset it anyway.
336 (message1, message1_nolog): Use message3.
337 (vmessage): Use a stack allocated buffer rather than f->message_buf.
338 (with_echo_area_buffer): Remove last two arguments. Update all callers.
339 (set_message): Drop all but the second arg, which has to be a string.
340 (set_message_1): Simplify now that we know that a1 is NULL and the
341 second arg is a string.
342 * frame.h (struct frame): Remove `message_buf' field.
343 Use glyphs_initialized_p instead.
344 (FRAME_MESSAGE_BUF): Remove macro.
345 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
346 * lisp.h (message2, message2_nolog): Remove declarations.
347 (message3, message3_nolog): Update declarations.
348 * keyboard.c (read_char_minibuf_menu_text)
349 (read_char_minibuf_menu_width): Remove vars.
350 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
351 to correctly handle multibyte strings.
352 * frame.c (delete_frame): Don't free message_buf any more.
353 * editfns.c (message_text, message_length): Remove vars.
354 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
355 * fileio.c (auto_save_error): Use message3 instead of message2.
356 * dispnew.c (adjust_frame_message_buffer): Remove function.
358 2013-01-23 Eli Zaretskii <eliz@gnu.org>
360 * w32term.c (w32fullscreen_hook): Account correctly for the screen
361 real estate used for the tool bar and the menu bar.
363 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
365 * insdel.c (prepare_to_modify_buffer): Force redisplay if
366 hidden buffer is prepared to modification (Bug#13164).
368 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
370 * window.h (struct window): Change window_end_valid member from
371 Lisp_Object to a bitfield. Adjust comments.
372 (wset_window_end_valid): Remove.
373 * window.c (adjust_window_count): Clear window_end_valid.
374 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
375 (Fwindow_line_height, set_window_buffer, Frecenter)
376 (Fsplit_window_internal, Fdelete_other_windows_internal)
377 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
378 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
379 * xdisp.c (check_window_end, reconsider_clip_changes)
380 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
381 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
382 (find_first_unchanged_at_end_row, try_window_id): Likewise.
384 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
386 * xdisp.c (mark_window_display_accurate): Simplify the loop
387 assuming that the only one of vchild, hchild or buffer window
388 slots is non-nil. Call mark_window_display_accurate_1 for
389 the leaf windows only.
390 (mark_window_display_accurate_1): Always assume leaf window.
393 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
395 * emacs.c (Qkill_emacs_hook): Now static.
397 * fileio.c (Finsert_file_contents): Simplify.
398 Remove unnecessary assignments and tests.
400 2013-01-21 Eli Zaretskii <eliz@gnu.org>
402 * w32.c (acl_set_file): Don't test for errors unless
403 set_file_security returns FALSE. Avoids spurious errors when
406 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
408 * fileio.c (Finsert_file_contents): Revert code introduced at
409 2013-01-18 in favor of the simpler and generally better fix.
410 Save stack space by removing 'buffer' and reusing 'read_buf'
413 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
415 * lisp.h (eabs): Define unconditionally (Bug#13419).
416 The old "#if !defined (eabs)" was an unnecessary revenant of back
417 when this macro was called "abs". Document 'eabs' better.
419 2013-01-19 Glenn Morris <rgm@gnu.org>
421 * fns.c (Frandom): Doc fix.
423 2013-01-19 Eli Zaretskii <eliz@gnu.org>
425 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
426 segfault when there are lots of overlays.
428 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
429 when there are lots of overlays. See
430 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
431 for the details and a way to reproduce.
433 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
435 * fileio.c: Use O_APPEND to append.
436 This corresponds better to the natural interpretation of "append",
437 and avoids the need to open the output file twice, or to invoke
438 lseek when APPEND is neither nil nor a number.
439 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
440 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
441 file possibly twice, and lseeking to its end; this avoids the
442 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
443 at the same time: the combination is never needed and apparently
444 it doesn't work with DOS_NT.
446 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
447 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
449 Allow floating-point file offsets.
450 Problem reported by Vitalie Spinu in
451 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
452 * fileio.c (emacs_lseek): Remove.
453 (file_offset): New function.
454 (Finsert_file_contents, Fwrite_region): Use it.
456 2013-01-19 Chong Yidong <cyd@gnu.org>
458 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
459 aborting on Fsignal (Bug#13289).
461 2013-01-19 Eli Zaretskii <eliz@gnu.org>
463 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
464 set_file_security as failure due to insufficient privileges.
465 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
466 (fstat): Return owner and group like 'stat' and 'lstat' do.
468 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
470 Work around bug in CIFS and vboxsf file systems (Bug#13149).
471 The bug was observed on Ubuntu operating inside a virtual machine,
472 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
473 The workaround introduces a race condition on non-buggy hosts,
474 but it's an unlikely race and anyway there's a nearly identical
475 nearby race that can't be fixed.

956 2012-12-23 Eli Zaretskii <eliz@gnu.org>
958 * w32.c (acl_set_file): If setting the file security descriptor
959 fails, and the new DACL is identical to the existing one, silently
960 return success. This fixes problems for users backing up their
961 own files without having the necessary privileges for setting
962 security descriptors.
964 * w32proc.c (reader_thread): Do not index fd_info[] with negative
966 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
967 after WaitForSingleObject returns normally. This expedites reader
968 thread shutdown when delete_child triggers it.
969 (reap_subprocess): More accurate commentary for why we call
970 delete_child only when cp->fd is negative.
972 * w32.c (sys_close): Do not call delete_child on a subprocess
973 whose handle is not yet closed. Instead, set its file descriptor
974 to a negative value, so that reap_subprocess will call
975 delete_child on that subprocess when its SIGCHLD arrives.
976 This avoids closing handles used for communications between sys_select
977 and reader_thread, which doesn't give sys_select a chance to
978 notice that the process exited and invoke the SIGCHLD handler for
981 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
983 * nsfns.m (Fns_do_applescript): Run event loop until script has
984 been executed (Bug#12969).
985 (ns_run_ascript): Chech as_script for nil, set to nil after
988 2012-12-22 Martin Rudalics <rudalics@gmx.at>
990 * window.c (Fselect_window): Reword doc-string (Bug#13248).
992 2012-12-22 Eli Zaretskii <eliz@gnu.org>
994 * w32term.c (w32fullscreen_hook): New function.
995 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
997 2012-12-21 Eli Zaretskii <eliz@gnu.org>
999 * fileio.c (Finsert_file_contents): Doc fix.
1001 * w32proc.c (new_child, delete_child, find_child_pid): For a
1002 subprocess, consider its slot being in use as long as its process
1003 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1004 slot when a new process is started immediately after killing
1005 another one, without waiting enough time for the first process to
1006 be reaped and resources allocated for it be orderly freed.
1008 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1010 2012-12-21 Chong Yidong <cyd@gnu.org>
1012 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1014 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1016 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1018 * w32.c (get_name_and_id): Always pass NULL as the first argument
1019 of lookup_account_sid. Avoids crashes with UNC file names that
1020 refer to DFS domains, not to specific machine names. (Bug#12621)
1021 Remove now unused argument FNAME; all callers changed.
1022 (get_file_owner_and_group): Remove now unused argument FNAME; all
1025 2012-12-21 Chong Yidong <cyd@gnu.org>
1027 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1028 error for invalid chars, don't check for a nil return value.
1030 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1032 Avoid calls to CHAR_TO_BYTE if byte position is known.
1033 * editfns.c (make_buffer_string_both): Use move_gap_both.
1034 (Fbuffer_string): Use make_buffer_string_both.
1035 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1037 (buf_bytepos_to_charpos): Likewise.
1038 (charpos_to_bytepos): Remove.
1039 * fileio.c (Finsert_file_contents): Use move_gap_both.
1040 * search.c (Freplace_match): Likewise.
1041 * process.c (process_send_region): Likewise. Use convenient
1042 names for byte positions.
1043 * lisp.h (charpos_to_bytepos): Remove prototype.
1044 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1045 * insdel.c (move_gap): Likewise.
1047 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
1049 * xdisp.c (redisplay_internal): Remove now-unused local.
1051 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1053 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1054 (redisplay_internal): Don't bother selecting the frame to get the
1055 proper value of frame-local variables (bug#13225).
1057 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1059 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1060 Rename 4th argument since it may be buffer or string. Adjust comment.
1061 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1063 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1065 * coding.c (Fdetect_coding_region): Do not check start and end with
1066 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1067 (code_convert_region): Likewise.
1069 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1071 * w32.c (acl_get_file, acl_set_file): Run the file name through
1072 map_w32_filename, and resolve any symlinks in the file name, like
1074 (acl_set_file): Call revert_to_self, if any privileges were
1077 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1079 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1080 ($(BLD)/w32.$(O)): Update dependencies.
1082 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1084 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1085 propagate redisplay's scrolling (if any) to the right window.
1086 (redisplay_internal): Use ensure_selected_frame.
1087 (display_mode_lines): Complete last fix.
1088 * window.c (select_window_1): New func, extracted from select_window.
1089 (select_window): Use it.
1090 * window.h (select_window_1): Declare.
1092 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1094 Emulate Posix ACL APIs on MS-Windows.

1114 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1116 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1118 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1119 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1120 for some of that bug's symptoms can now cause Emacs to abort.
1121 Remove the workaround.
1122 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1123 The bug that caused SIGCHLD to get lost has been fixed, and the
1124 workaround for it can now cause Emacs to abort.
1126 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1128 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1129 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1130 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1132 2012-12-16 Romain Francoise <romain@orebokech.com>
1134 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1135 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1136 and copy ACL entries of file in addition to SELinux context if set.
1137 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1139 * Makefile.in (LIBACL_LIBS): New macro.

1144 * fileio.c (internal_delete_file): Use bool for boolean.
1146 2012-12-15 Eli Zaretskii <eliz@gnu.org>
1148 Fix bug #13079 on MS-Windows with temp files not being deleted.

1154 * w32proc.c (new_child): Initialize input_file and
1155 pending_deletion members of the child.
1156 (delete_child): Delete the child's temporary input file, if any,
1157 that is pending deletion.
1158 (register_child): First argument is now pid_t.
1159 (record_infile, record_pending_deletion): New functions.
1160 (reap_subprocess): Fix a typo in DebPrint string.
1161 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1163 * fileio.c (internal_delete_file): Return an int again: non-zero
1164 if delete-file succeeds, zero otherwise.
1166 * lisp.h (internal_delete_file): Adjust prototype.
1168 * callproc.c (Fcall_process): Don't overwrite infile with result
1170 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1171 asynchronous subprocess, record the name of the input file name,
1173 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1174 delete the file, record it as pending deletion when the subprocess
1177 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1179 * editfns.c [HAVE_PWD_H]: Include grp.h.
1181 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

1185 Fix permissions bugs with setgid directories etc. (Bug#13125)
1186 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1187 to mark it as a placeholder. The old value was often wrong.
1188 The only user of this attribute has been changed to use
1189 file-ownership-preserved-p instead, with its new group arg.
1190 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1192 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

1197 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1199 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1200 try to get accurate owner and group information from NT file
1201 security APIs. This is to make most callers of 'stat' and
1202 'lstat', which don't need that information, much faster.
1204 * dired.c (Ffile_attributes) [WINDOWSNT]:
1205 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1206 owner and group information from 'lstat'.
1208 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1210 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1211 as that confuses set-auto-coding, so insist on the head-read
1212 returning the full 1024 bytes. Let lseek compute the tail offset;
1213 less work for us. Do not ignore I/O errors when reading the tail.
1215 * xdisp.c: Minor style fixes.
1216 (init_iterator): Hoist assignment out of if-expression.
1217 (markpos_of_region): Callers now test for sign, not for -1.

1230 * search.c (search_buffer): Check the inverse translations of each
1231 character in pattern when the buffer being searched is unibyte.
1234 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1236 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1237 files, fixing a regression from 24.2.
1238 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1240 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1242 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1243 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1244 Remove unnecessary S_ISLNK test, as (contra the comments) this
1245 function can't copy symlinks. Improve quality of error message
1246 when attempting to copy files that are neither regular files nor

1254 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1255 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1257 2012-12-12 Daniel Colascione <dancol@dancol.org>
1259 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1260 the dumped Emacs is not a sparse file, greatly improving Cygwin
1261 "make bootstrap" performance.
1263 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1265 * inotify.c (inotify_callback): Generate an Emacs event for every
1266 incoming inotify event.
1268 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1270 * xdisp.c (handle_face_prop): Fix logic of computing
1271 it->start_of_box_run_p.
1272 (append_space_for_newline): If the glyph row is R2L, reset the
1273 iterator's end_of_box_run_p flag before prepending the space glyph.
1274 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1275 iterator's start_of_box_run_p flag before prepending the stretch.
1276 (append_glyph, produce_image_glyph, append_composite_glyph)
1277 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1278 left_box_line_p and right_box_line_p flags of the glyph for R2L
1279 glyph rows. (Bug#13011)
1281 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1286 * window.c (replace_buffer_in_windows_safely): Do nothing
1287 if buffer is not shown in a window.

1293 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1294 encoded_file_name, which is what it is.
1296 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1298 Consistently use marker_position and marker_byte_position.

1328 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1329 (hinst): Remove unneeded extern declaration.
1330 (_start): Remove initialization of above variables; remove
1331 initialization of hinst, as cache_system_info now does that.

1440 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
1442 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
1444 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
1445 DWORD_PTR, for compatibility with 64-bit builds.
1447 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
1448 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
1449 (system_process_attributes): Use SIZE_T rather than DWORD, for
1450 compatibility with 64-bit builds.
1452 2012-12-10 Christopher Schmidt <christopher@ch.ristopher.com>

1456 2012-12-10 Eli Zaretskii <eliz@gnu.org>
1458 * indent.c (Fvertical_motion): If a display string will be
1459 displayed on the left or the right margin, don't consider it as a
1460 factor in cursor positioning. (Bug#13108)
1462 2012-12-10 Martin Rudalics <rudalics@gmx.at>
1464 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
1466 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>

1471 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1473 * w32.c (unsetenv): Return 0 if the input string is too long.
1475 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1477 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1478 * alloc.c (xputenv): New function.
1479 * dbusbind.c (Fdbus_init_bus):
1481 * xterm.c (x_term_init):
1482 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1483 * editfns.c (initial_tz): Move static var decl up.
1484 (tzvalbuf_in_environ): New static var.
1485 (init_editfns): Initialize these two static vars.
1486 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1487 Save old TZ value on stack, if it's small.
1488 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1489 instead, use xputenv+unsetenv to set and restore TZ.
1490 (environbuf): Remove static var. All uses removed.
1491 (Fset_time_zone_rule): Do not save TZ and environ;
1492 no longer needed here.
1493 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1494 Move to inside set_time_zone_rule; they don't need file scope any more.
1495 (set_time_zone_rule): Maintain the TZ=value string separately.
1496 (syms_of_editfns): Don't initialize initial_tz;
1497 init_editfns now does it.
1498 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1499 * lisp.h (xputenv): New decl.
1501 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1503 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1505 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1507 * w32.c (unsetenv, sys_putenv): New functions.
1509 2012-12-08 Chong Yidong <cyd@gnu.org>
1511 * editfns.c (Finsert_char): Make the error message more
1512 informative (Bug#12992).
1514 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1516 Simplify get_lim_data.
1517 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1518 Remove USG and vlimit methods; no longer used these days.
1519 Add #error catchall just in case.
1521 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1522 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1523 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1524 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1525 (deleted_pid_list, Fdelete_process, create_process)
1526 (record_child_status_change, handle_child_signal, deliver_child_signal)
1527 (init_process_emacs, syms_of_process):
1528 Assume SIGCHLD is defined.
1529 (parse_signal): Remove. All uses removed.
1530 (abbr_to_signal): New static function.
1531 (Fsignal_process): Use it to convert signal names to ints.
1532 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1533 kill (getpgrp (), ...).
1534 (emacs_sigaction_init): Assume SIGCHLD is defined.
1535 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1536 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1537 * syssignal.h (EMACS_KILLPG): Remove.
1538 All uses replaced by 'kill' with a negative pid.
1539 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1540 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1542 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1544 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1545 This will cause a production Emacs to dump core instead of
1548 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1550 * frame.c (make_frame): Do not set window's buffer to t.
1551 * window.c (Fsplit_window_internal): Likewise. Previously it was
1552 used to indicate that the window is being set up. Now we use
1553 set_window_buffer for all new windows, so the condition in ...
1554 (Fset_window_buffer): ... is always true and can be removed.
1556 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1558 Convenient macro to check whether the buffer is hidden.
1559 * buffer.h (BUFFER_HIDDEN_P): New macro.
1560 * frame.c (make_frame): Use it. Adjust comment.
1561 * buffer.c (candidate_buffer): New function.
1562 (Fother_buffer, other_buffer_safely): Use it.
1564 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1566 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1567 if the child process is still running. Instead, exit the wait
1568 loop and return zero. (Bug#13086)
1570 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1572 * frame.h (x_char_width, x_char_height): Remove prototypes.
1573 * w32term.h (x_char_width, x_char_height): Likewise.
1574 * xfns.c (x_char_width, x_char_height): Remove.

1585 Fix a recently-introduced delete-process race condition.
1586 * callproc.c, process.h (record_kill_process):
1587 New function, containing part of the old call_process_kill.
1588 (call_process_kill): Use it.
1589 This does not change call_process_kill's behavior.
1590 * process.c (Fdelete_process): Use record_kill_process to fix a
1591 race condition that could cause Emacs to lose track of a child.
1593 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1595 Avoid code duplication between prev_frame and next_frame.
1596 * frame.c (candidate_frame): New function. Add comment.
1597 (prev_frame, next_frame): Use it. Adjust comment.
1599 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1601 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1602 fails, signal an error instead of continuing with an empty
1604 Encode expanded temp file pattern before passing it to mkstemp or
1607 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1608 Encode the file name before passing it to dostounix_filename, in
1609 case it will downcase it (under w32-downcase-file-names).
1612 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1614 Minor call-process cleanups.
1615 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1616 at the same time as other platforms, to simplify analysis.
1617 No need for fd0_volatile since we have synch_process_fd.
1618 Avoid needless emacs_close; arg is always negative.
1620 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1622 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1625 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1627 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1628 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1629 and mouse_face_hidden members to a bitfields.
1630 * frame.h (struct frame): Remove set-but-not-used space_width member.
1631 (FRAME_SPACE_WIDTH): Remove.
1632 * nsterm.m, w32term.c, xterm.c: Adjust users.
1633 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1634 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1635 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1636 members to a bitfields.
1638 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1640 Don't let call-process be a zombie factory (Bug#12980).
1641 Fixing this bug required some cleanup of the signal-handling code.
1642 As a side effect, this change also fixes a longstanding rare race
1643 condition whereby Emacs could mistakenly kill unrelated processes,
1644 and it fixes a bug where a second C-g does not kill a recalcitrant
1645 synchronous process in GNU/Linux and similar platforms.
1646 The patch should also fix the last vestiges of Bug#9488,
1647 a bug which has mostly been fixed on the trunk by other changes.
1648 * callproc.c, process.h (synch_process_alive, synch_process_death)
1649 (synch_process_termsig, sync_process_retcode):
1650 Remove. All uses removed, to simplify analysis and so that
1651 less consing is done inside critical sections.
1652 * callproc.c (call_process_exited): Remove. All uses replaced
1653 with !synch_process_pid.
1654 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1655 These take the role of what used to be in unwind-protect arg.
1657 (block_child_signal, unblock_child_signal):
1658 New functions, to avoid races that could kill innocent-victim processes.
1659 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1660 (call_process_kill): Record killed processes as deleted, so that
1661 zombies do not clutter up the system. Do this inside a critical
1662 section, to avoid a race that would allow the clutter.
1663 (call_process_cleanup): Fix code so that the second C-g works again
1664 on common platforms such as GNU/Linux.
1665 (Fcall_process): Create the child process in a critical section,
1666 to fix a race condition. If creating an asynchronous process,
1667 record it as deleted so that zombies do not clutter up the system.
1668 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1669 light of these changes. Omit unnecessary call to emacs_close
1670 before failure, as the unwind-protect code does that.
1671 * callproc.c (call_process_cleanup):
1672 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1673 * process.c (record_deleted_pid): New function, containing
1674 code refactored out of Fdelete_process.
1675 (Fdelete_process): Use it.
1676 (process_status_retrieved): Remove. All callers changed to use
1677 child_status_change.
1678 (record_child_status_change): Remove, folding its contents into ...
1679 (handle_child_signal): ... this signal handler. Now, this
1680 function is purely a handler for SIGCHLD, and is not called after
1681 a synchronous waitpid returns; the synchronous code is moved to
1682 wait_for_termination. There is no need to worry about reaping
1683 more than one child now.
1684 * sysdep.c (get_child_status, child_status_changed): New functions.
1685 (wait_for_termination): Now takes int * status and bool
1686 interruptible arguments, too. Do not record child status change;
1687 that's now the caller's responsibility. All callers changed.
1688 Reimplement in terms of get_child_status.
1689 (wait_for_termination_1, interruptible_wait_for_termination):
1690 Remove. All callers changed to use wait_for_termination.
1691 * syswait.h: Include <stdbool.h>, for bool.
1692 (record_child_status_change, interruptible_wait_for_termination):
1694 (record_deleted_pid, child_status_changed): New decls.
1695 (wait_for_termination): Adjust to API changes noted above.
1697 * bytecode.c, lisp.h (Qbytecode): Remove.
1698 No longer needed after 2012-11-20 interactive-p changes.
1700 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1702 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1703 the scroll margin, move point outside the margin. (Bug#13055)
1705 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1707 * gtkutil.c (my_log_handler): New function.
1708 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1710 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1712 * lisp.h (modify_region): Rename to...
1713 (modify_region_1): ...new prototype.
1714 * textprop.c (modify_region): Now static. Adjust users.
1715 * insdel.c (modify_region): Rename to...
1716 (modify_region_1): ...new function to work with current buffer.
1717 Adjust comment and users. Use true and false for booleans.
1719 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1721 * alloc.c (free_save_value): New function.
1722 (safe_alloca_unwind): Use it.
1723 * lisp.h (free_save_value): New prototype.
1724 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1726 (save_excursion_restore): Adjust to match saved data structure.
1727 Use free_save_value to offload some work from GC. Drop obsolete
1730 2012-12-03 Chong Yidong <cyd@gnu.org>
1732 * fileio.c (Vauto_save_list_file_name): Doc fix.
1734 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1736 * w32fns.c: Remove prototype of atof.
1737 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1739 (file_dialog_callback): Make it UINT_PTR.
1741 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1744 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1745 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1748 2012-12-03 Glenn Morris <rgm@gnu.org>
1750 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1752 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1754 Fix xpalloc confusion after memory is exhausted.
1755 * alloc.c (xpalloc): Comment fix.
1756 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1757 and signals an error, do not clear charset_table_size, as
1758 charset_table is still valid.
1759 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1761 Use execve to avoid need to munge environ (Bug#13054).
1762 * callproc.c (Fcall_process):
1763 * process.c (create_process):
1764 Don't save and restore environ; no longer needed.
1765 * callproc.c (child_setup):
1766 Use execve, not execvp, to preserve environ.
1768 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1770 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1772 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1774 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1775 display for sliced images (Bug#10500).
1777 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1779 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1781 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1782 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1784 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1786 * xdisp.c (window_outdated): Remove eassert since it hits
1787 some suspicious corner cases (see Bug#13007 and Bug#13012).
1788 (mode_line_update_needed): New function.
1789 (redisplay_internal, redisplay_window): Use it.
1790 (ensure_selected_frame): New function.
1791 (redisplay_internal, unwind_redisplay): Use it.
1792 (redisplay_internal): Move comment about buffer_shared...
1793 (buffer_shared_and_changed): ...near to its real use.
1795 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1797 * callproc.c (Fcall_process): Don't misreport vfork failure.
1799 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1801 * callproc.c (Fcall_process): Fix vfork portability problems.
1802 Do not assume that fd[0], count, filefd, and save_environ survive
1803 vfork. Fix bug whereby wrong errno value could be reported for
1804 pipe failure. Some minor cleanups, too, as follows. Move buf and
1805 bufsize to the context where they're needed. Change new_argv to
1806 be of type char **, as this is more convenient and avoids casts.
1807 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1808 Now local constants, not macros.
1810 2012-11-18 Kenichi Handa <handa@gnu.org>
1812 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1813 for the variable "f".
1815 2012-11-13 Kenichi Handa <handa@gnu.org>
1817 * font.c (font_unparse_xlfd): Exclude special characters from the
1818 generating XLFD name.
1820 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1822 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
1823 * dired.c (stat_uname, stat_gname):
1824 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1826 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1830 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1831 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1832 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1833 * lread.c (readbyte_from_file): Assume EINTR is defined.
1834 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1835 Assume EIO and EAGAIN are defined.
1836 * unexcoff.c (write_segment): Assume EFAULT is defined.
1838 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1840 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1843 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1844 highlighting on the frame was cleared. Prevents assertion
1845 violations when repeatedly clicking on the "Top" link of the
1846 "bread-crumbs" in Info buffers.
1848 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1850 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1852 2012-11-24 Ken Brown <kbrown@cornell.edu>

1855 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1856 were always defined.
1858 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1860 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1861 between bpos_covered and bpos_max. This fixes cursor display when
1862 several display strings follow each other.
1864 * .gdbinit (pgx): If the glyph's object is a string, display the
1865 pointer to string data, rather than the value of the string object
1866 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1868 * indent.c (Fvertical_motion): If the starting position is covered
1869 by a display string, return to one position before that, to avoid
1870 overshooting it inside move_it_to. (Bug#12930)
1872 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1874 * frame.h (struct frame): Remove display_preempted member

1877 * w32menu.c (pending_menu_activation): Remove since not
1879 (set_frame_menubar): Adjust user.
1880 * w32term.h (struct x_output): Drop outdated #if 0 code.
1881 (struct w32_output): Use bitfields for explicit_parent,
1882 asked_for_visible and menubar_active members.
1883 Drop unused pending_menu_activation member.
1884 * xterm.h (struct x_output): Drop outdated #if 0 code.
1885 Use bitfields for explicit_parent, asked_for_visible,
1886 has_been_visible and net_wm_state_hidden_seen members.
1888 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1890 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1891 of a literal "/". (Bug#12955)
1892 (gl-stamp): Invoke fc.exe directly, not through cmd.
1894 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1896 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1897 * dired.c: Assume HAVE_DIRENT_H.
1898 (NAMLEN): Remove, replacing with ...
1899 (dirent_namelen): New function. All uses changed. Use the GNU macro
1900 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1901 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1902 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1903 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1905 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1906 * ndir.h: Rename to ../nt/inc/dirent.h.
1907 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1908 Do not include <dirent.h>; no longer needed.
1909 * w32.c: Include <dirent.h> rather than "ndir.h".
1911 2012-11-23 Chong Yidong <cyd@gnu.org>
1913 * xftfont.c (xftfont_open): Remove duplicate assignment.
1915 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1917 * alloc.c (Fgarbage_collect): Unblock input after clearing
1918 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1919 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1920 * msdos.c (IT_frame_up_to_date): Use it here...
1921 * w32term.c (w32_frame_up_to_date): ...here...
1922 * xterm.c (XTframe_up_to_date): ...and here...
1923 * nsterm.m (ns_frame_up_to_date): ...but not here.
1924 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1926 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1927 Do not check whether GC is in progress.
1929 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1931 * xdisp.c (window_buffer_changed): New function.
1932 (update_menu_bar, update_tool_bar): Use it to
1933 simplify large 'if' statements.

1935 'tail' and 'frame' local variables.
1937 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1939 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1940 with Windows system header.
1942 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1944 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1945 * alloc.c: Assume unistd.h exists.
1946 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1947 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1948 (getwd) [USG]: Remove; no longer needed.
1949 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1950 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1951 * w32.h (getcwd): Remove decl.
1953 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1955 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1956 Make it set selected_window as well.
1957 (update_tool_bar): Use it.
1959 2012-11-21 Ken Brown <kbrown@cornell.edu>
1961 * emacs.c (main): Set the G_SLICE environment variable for all
1962 Cygwin builds, not just GTK builds. See
1963 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1965 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1967 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1968 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1969 Define for the MSVC compiler.
1971 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1973 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1974 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1975 dostounix_filename. Prevents crashes down the road, because
1976 dostounix_filename assumes it gets a unibyte string.
1977 Reported by Michel de Ruiter <michel@sentient.nl>, see
1978 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1980 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1985 * eval.c (Fcommandp): Ignore Qunbound.
1986 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1987 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1988 Test NILP rather than Qunbound.
1989 (Ffmakunbound): Set to Qnil.
1990 (Fsymbol_function): Never signal an error.
1991 (Finteractive_form): Ignore Qunbound.
1993 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1995 * eval.c (interactive_p): Remove no-longer-used decl.
1997 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1999 * xdisp.c (buffer_shared): Adjust comment.
2000 (buffer_shared_and_changed): New function.
2001 (prepare_menu_bars, redisplay_internal): Use it to
2002 decide whether all windows or frames should be updated.
2003 (window_outdated): New function.
2004 (text_outside_line_unchanged_p, redisplay_window): Use it.
2005 (redisplay_internal): Likewise. Fix indentation.
2007 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2009 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2010 (syms_of_eval): Remove corresponding defsubr.
2011 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2013 2012-11-19 Daniel Colascione <dancol@dancol.org>
2015 * w32fns.c (Fx_file_dialog):
2016 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2017 cygwin_convert_file_name*.
2019 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2020 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2022 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2024 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2026 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2028 * w32select.c: Include w32common.h before w32term.h, so that
2029 windows.h gets included before w32term.h uses some of its
2030 features, see below.
2032 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2034 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2036 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2038 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2040 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2041 (ns_select): Return at once if events are held (Bug#12834).
2043 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2045 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2046 Needed following 2012-10-20 change. (Bug#12902)
2048 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2050 * w32proc.c (waitpid): Remove unused label get_result.
2052 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2054 * makefile.w32-in (SYSWAIT_H): New macro.
2055 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2056 ($(BLD)/sysdep.$(O)): Update dependencies.
2058 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2060 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2061 * callproc.c (relocate_fd): Assume F_DUPFD.
2062 * emacs.c, term.c (O_RDWR): Remove.
2063 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2064 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2065 * nsterm.m: Assume <fcntl.h> exists.
2066 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2067 (create_pty, Fmake_network_process, server_accept_connection)
2068 (wait_reading_process_output, init_process_emacs):
2070 (wait_reading_process_output): Put in a special case for WINDOWSNT
2071 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2072 It's not clear this is needed, but it's a more-conservative change.
2073 (create_process): Assume FD_CLOEXEC.
2074 (create_process, create_pty): Assume O_NOCTTY.
2075 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2076 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2077 Omit if not DOS_NT, since F_GETFL is not defined there.
2078 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2079 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2081 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2082 lack it, since gnulib guarantees this.
2083 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2085 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2087 * w32.c (faccessat): Pretend that directories have the execute bit
2088 set. Emacs expects that, e.g., in files.el:cd-absolute.
2090 * w32proc.c (create_child): Don't clip the PID of the child
2091 process to fit into an Emacs integer, as this is no longer a
2093 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2094 reaping only the process specified by PID argument, if that is
2095 positive. Use PID instead of dead_child to know which process to
2096 reap. Wait for the child to die only if WNOHANG is not in
2098 (sys_select): Don't set dead_child.
2100 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2101 as it is no longer needed.
2103 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2105 (record_child_status_change): Remove the setting of
2106 record_at_most_one_child for the !WNOHANG case.
2108 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2110 Fix problems in ns port found by static checking.
2111 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2112 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2113 not to process group.
2114 (ns_select): Use emacs_write, not write, as that's more robust
2115 in the presence of signals.
2116 (fd_handler:): Check for read errors.
2118 2012-11-16 Glenn Morris <rgm@gnu.org>
2120 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2122 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2124 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2126 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2128 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2129 use the same value of thread handle.
2130 (start_timer_thread): If the timer thread exited (due to error),
2131 clean up by closing the two handles it used. Duplicate the caller
2132 thread's handle here, so it gets duplicated only once, when
2133 launching the timer thread. Set priority of the timer thread, not
2135 (getitimer): Don't duplicate the caller thread's handle here.
2138 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2140 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2143 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2145 Remove no-longer-used pty_max_bytes variable.
2146 * process.c (pty_max_bytes): Remove; unused.
2147 (send_process): Do not set it.
2149 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2151 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2152 Update dependencies.
2154 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2156 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2157 This follows up on the 2012-09-29 patch that removed indirection
2158 for the 'function' field. Reported by Sergey Vinokurov in
2159 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2161 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2163 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2164 different name, as the MS runtime does not have such a function,
2165 and probably never will.) All callers changed. Ignore DIRFD
2166 value if PATH is an absolute file name, to match Posix spec
2167 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2170 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2172 * xdisp.c (echo_area_display, redisplay_internal):
2173 Omit redundant check whether frame_garbaged is set.
2175 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2177 Use faccessat, not access, when checking file permissions (Bug#12632).
2178 This fixes a bug that has been present in Emacs since its creation.
2179 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2180 which must set some sort of record. (Torek's bug report was against
2181 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2182 same common flaw.) See Torek's Usenet posting
2183 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2184 Posted: Fri Apr 8 14:18:56 1983.
2185 * Makefile.in (LIB_EACCESS): New macro.
2187 * callproc.c (init_callproc):
2188 * charset.c (init_charset):
2189 * fileio.c (check_existing, check_executable, check_writable)
2191 * lread.c (openp, load_path_check):
2192 * process.c (allocate_pty):
2194 Use effective UID when checking permissions, not real UID.
2195 * callproc.c (init_callproc):
2196 * charset.c (init_charset):
2197 * lread.c (load_path_check, init_lread):
2198 Test whether directories are accessible, not merely whether they exist.
2199 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2200 * fileio.c (check_existing, check_executable, check_writable)
2202 Use symbolic names instead of integers for the flags, as they're
2204 (check_writable): New arg AMODE. All uses changed.
2205 Set errno on failure.
2206 (Ffile_readable_p): Use faccessat, not stat + open + close.
2207 (Ffile_writable_p): No need to call check_existing + check_writable.
2208 Just call check_writable and then look at errno. This saves a syscall.
2209 dir should never be nil; replace an unnecessary runtime check
2210 with an eassert. When checking the parent directory of a nonexistent
2211 file, check that the directory is searchable as well as writable, as
2212 we can't create files in unsearchable directories.
2213 (file_directory_p): New function, which uses 'stat' on most platforms
2214 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2215 (Ffile_directory_p, Fset_file_times): Use it.
2216 (file_accessible_directory_p): New function, which uses a single
2217 syscall for efficiency.
2218 (Ffile_accessible_directory_p): Use it.
2219 * xrdb.c (file_p): Use file_directory_p.
2220 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2221 * lread.c (openp): When opening a file, use fstat rather than
2222 stat, as that avoids a permissions race. When not opening a file,
2223 use file_directory_p rather than stat.
2224 (dir_warning): First arg is now a usage string, not a format.
2225 Use errno. All uses changed.
2226 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2227 that merely introduced a race.
2228 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2229 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2230 and similarly for the other O_* flags.
2231 * w32.c (sys_faccessat): Rename from sys_access and switch to
2232 faccessat's API. All uses changed.
2233 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2234 (magic_db): Rename from magic_file_p.
2235 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2236 char *, so that we don't have to test for file existence
2237 separately from opening the file for reading. This removes a race
2238 fixes a permission-checking problem, and simplifies the code.
2240 (file_p): Remove; no longer needed.
2242 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2244 Omit glyphs initialization at startup.
2245 * dispnew.c (glyphs_initialized_initially_p): Remove.
2246 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2247 (Fredraw_frame): Move actual code from here...
2248 (redraw_frame): ...to here. Add eassert. Adjust comment.
2249 (Fredraw_display): Use redraw_frame.
2250 * xdisp.c (clear_garbaged_frames): Likewise.
2252 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2254 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2255 passed to pint2str and pint2hrstr to be at most the size of the
2256 frame's decode_mode_spec_buffer. This avoids crashes with very
2257 large values of FIELD_WIDTH argument to decode_mode_spec.
2260 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2262 Fix a race with verify-visited-file-modtime (Bug#12863).
2263 Since at least 1991 Emacs has ignored an mtime difference of no
2264 more than one second, but my guess is that this was to work around
2265 file system bugs that were fixed long ago. Since the race is
2266 causing problems now, let's remove that code.
2267 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2268 whose time stamp is off by no more than a second. Insist that the
2269 file time stamps match exactly.
2271 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2273 * frame.h (struct frame): Convert external_tool_bar member to
2274 1-bit unsigned bitfield.
2275 * termhooks.h (struct terminal): Remove mouse_moved member since
2276 all users are long dead. Adjust comment on mouse_position_hook.
2278 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2280 Simplify by using FOR_EACH_FRAME here and there.
2281 * frame.c (next_frame, prev_frame, other_visible_frames)
2282 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2283 * w32term.c (x_window_to_scroll_bar): Likewise.
2284 * window.c (window_list): Likewise.
2285 * xdisp.c (x_consider_frame_title): Likewise.
2286 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2287 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2288 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2289 * xmenu.c (menubar_id_to_frame): Likewise.
2290 * xselect.c (frame_for_x_selection): Likewise.
2291 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2292 (x_window_to_menu_bar): Likewise.
2293 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2295 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2297 * data.c (Qdefalias_fset_function): Now static.
2299 Another tweak to vectorlike_header change.
2300 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2301 Remove, and replace all uses with ...
2302 (next_in_free_list, set_next_in_free_list):
2303 New functions, which respect C's aliasing rules better.
2305 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2307 * window.c (list4i): Rename from 'quad'. All uses changed.
2308 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2310 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2312 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2313 warning about mixing declarations and code in ISO C90.
2315 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2317 * window.c (Fsplit_window_internal): Set combination limit of
2318 new parent window to t iff Vwindow_combination_limit is t;
2319 fixing a regression introduced with the change from 2012-09-22.
2320 (Fset_window_combination_limit): Fix doc-string.
2322 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2324 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2325 amount when the scroll margins are too large. When scrolling
2326 backwards in the buffer, give up if cannot reach point or the
2327 scroll margin within a reasonable number of screen lines.
2328 Fixes point position in window under scroll-up/down-aggressively when
2329 point is positioned many lines beyond the window top/bottom.
2332 * ralloc.c (relinquish): If real_morecore fails to return memory
2333 to the system, don't crash; instead, leave the last heap
2334 unchanged and return. (Bug#12774)
2336 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2338 * lisp.h (AUTOLOADP): New macro.
2339 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2340 * data.c (Ffset): Remove special ad-advice-info handling.
2341 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2343 (Finteractive_form): Simplify.
2344 (Fquo): Don't insist on having at least 2 arguments.
2345 (Qdefalias_fset_function): New var.

2364 Tweak last vectorlike_header change.
2365 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2366 vectorlike object on the free list. This is introduced to avoid
2367 some (but not all) pointer casting and aliasing problems, see
2368 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2369 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

2401 special hash function containing a comparison that always yields 1.
2403 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2405 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2406 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2407 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2410 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2412 * image.c (xpm_make_color_table_h): Fix compiler error because
2413 make_hash_table changed.
2415 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2417 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2419 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2421 Use ad-hoc comparison function for the profiler's hash-tables.
2422 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2423 (make_log): Use them.
2424 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2425 call Fequal any more.

2434 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2435 (hash_lookup, hash_remove_from_table): Move assertion checking of
2436 hashfn result here. Check hash-equality before calling cmpfn.

2449 value of w32-scroll-lock-modifier is neither nil nor one of the
2450 known key modifiers. (Bug#12806)
2452 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2454 Shrink struct vectorlike_header to the only size field.
2455 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2457 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

2482 (allocate_vectorlike): Likewise.
2483 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2484 Add easserts. Adjust XSETPVECTYPESIZE usage.
2485 (allocate_buffer): Use BUFFER_PVEC_INIT.
2486 (live_vector_p): Adjust to match large vector.
2487 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2488 * buffer.h (struct buffer): Add next member.

2499 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2501 * keyboard.c (event_to_kboard): Do not dereference
2502 frame_or_window field of SELECTION_REQUEST_EVENT
2503 and SELECTION_CLEAR_EVENT events (Bug#12814).
2504 * xterm.h (struct selection_input_event): Adjust comment.
2506 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2508 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2509 such as Scroll Lock, if the respective keys are treated as
2510 function keys, not as modifiers. This avoids destroying non-ASCII
2511 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2513 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2515 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2517 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2519 Restore some duplicate definitions (Bug#12814).
2520 This undoes part of the 2012-11-03 changes. Some people build
2521 with plain -g rather than with -g3, and they need the duplicate
2522 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2523 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2524 Define as macros, as well as as enums or as constants.
2526 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2528 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2529 to keypad keys (Bug#12816).
2531 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2533 Minor adjustments of recently-changed frame functions.
2534 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2535 known to be a frame (we're in the FRAMEP branch).
2536 * lisp.h (Qframep): Remove decl. frame.h declares this.
2537 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2538 since they're meant for Lisp fixnum values.
2540 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2542 * window.c (Fwindow_combination_limit): Revert to the only
2543 required argument and adjust docstring as suggested in
2544 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2545 by Martin Rudalics <rudalics@gmx.at>.
2547 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2549 Widely used frame validity and checking functions.
2550 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2551 * frame.c (decode_live_frame, decode_any_frame): New functions.
2552 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2553 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2554 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

2562 * lisp.h (frame_buffer_predicate): Remove prototype.
2563 * buffer.c (Fother_buffer): Use decode_any_frame.
2564 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2565 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2566 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2567 (Fclose_font, Ffont_info): Use decode_live_frame.
2568 * fontset.c (check_fontset_name): Likewise.
2569 * terminal.c (Fframe_terminal): Likewise.
2570 * w32fns.c (check_x_frame): Likewise.
2571 * window.c (Fminibuffer_window, Fwindow_at)
2572 (Fcurrent_window_configuration): Likewise.
2573 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2574 Likewise. Allow zero number of arguments. Adjust docstring.
2575 * dispnew.c (Fredraw_frame): Likewise.
2576 * xfaces.c (frame_or_selected_frame): Remove.
2577 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2578 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2579 (Fframe_face_alist): Use decode_live_frame.
2580 * xfns.c (check_x_frame): Likewise.
2582 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2584 * window.c (quad): New function.
2585 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2586 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2587 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2588 (Fwindow_line_height): Use it.
2589 (Fwindow_fringes): Use list3.
2590 (Fwindow_scroll_bars): Use list4.
2591 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2592 (Fwindow_combination_limit): Allow zero number of arguments.
2594 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2596 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2598 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2599 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2600 file descriptor 2 for standard error. (Bug#12805)
2602 2012-11-05 Chong Yidong <cyd@gnu.org>
2604 * process.c (wait_reading_process_output): Revert previous change.
2606 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2608 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2609 This removes code that has been obsolete since around 1990.
2610 * callproc.c (Fcall_process):
2612 * process.c (create_process):
2613 * term.c (dissociate_if_controlling_tty):
2614 Assume setsid exists.
2615 * callproc.c (child_setup): Assume setpgid exists and behaves as
2616 per POSIX.1-1988 or later.
2617 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2618 * emacs.c (shut_down_emacs):
2619 * sysdep.c (sys_suspend, init_foreground_group):
2620 Assume getpgrp behaves as per POSIX.1-1998 or later.
2621 * msdos.c (setpgrp): Remove.
2622 (tcgetpgrp, setpgid, setsid): New functions.
2623 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2624 * term.c (no_controlling_tty): Remove; unused.
2625 * w32proc.c (setpgrp): Remove.
2626 (setsid, tcgetpgrp): New functions.
2628 Simplify by assuming __fpending.
2629 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2630 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2631 Do not assume that __fpending's result fits in int.
2633 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2635 Remove EMACS_OUTQSIZE+sleep hack.
2636 * dispnew.c (update_frame_1): Remove hack for terminals slower
2637 than 2400 bps, which throttled Emacs by having it sleep.
2638 This code hasn't worked since at least 2007, when the multi-tty stuff
2639 was added, and anyway those old terminals are long dead.
2640 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2641 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2643 Fix data-loss with --version (Bug#9574).
2644 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2645 as we can't assume that emacs_strerror is initialized, and strerror
2646 is good enough here.
2647 (main): Invoke atexit earlier, to catch earlier instances of
2648 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2650 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2652 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2653 (keyDown): Remap keypad keys to X11 virtual key codes.
2655 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2657 Fix data-loss with --batch (Bug#9574).
2658 * emacs.c: Include <close-stream.h>.
2659 (close_output_streams): New function.
2660 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2661 and handles errors appropriately.
2662 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2665 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2666 The symptom is a diagnostic "GLib-WARNING **: In call to
2667 g_spawn_sync(), exit status of a child process was requested but
2668 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2669 waitpid(), so exit status can't be returned." The diagnostic
2670 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2671 The real bug is a race condition between Emacs and glib: Emacs
2672 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2673 so that glib can't find it. Work around the bug by invoking
2674 waitpid only on subprocesses that Emacs itself creates.
2675 * process.c (create_process, record_child_status_change):
2676 Don't use special value -1 in pid field, as the caller now must
2677 know the pid rather than having the callee infer it.
2678 The inference was sometimes incorrect anyway, due to another race.
2679 (create_process): Set new 'alive' member if child is created.
2680 (process_status_retrieved): New function.
2681 (record_child_status_change): Use it.
2682 Accept negative 1st argument, which means to wait for the
2683 processes that Emacs already knows about. Move special-case code
2684 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2685 processes that have already been waited for, by testing and
2686 clearing new 'alive' member.
2687 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2688 now does this internally.
2689 (handle_child_signal): Let record_child_status_change do all
2690 the work, since we do not want to reap all exited child processes,
2691 only the child processes that Emacs itself created.
2692 * process.h (Lisp_Process): New boolean member 'alive'.
2694 Omit duplicate definitions no longer needed with gcc -g3.
2695 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2696 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2697 Define only as macros. There's no longer any need to also define
2698 these symbols as enums or as constants, since we now assume
2699 gcc -g3 when debugging.
2701 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2703 * lisp.mk: Adjust comments to the fact that term/internal is now
2704 loaded from loadup.el.
2706 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2707 (msdos_fatal_signal): New function.
2708 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2711 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2712 for GCC versions before 4.
2713 (emacs_raise): Define to call msdos_fatal_signal.
2715 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2716 iterator when starting in the middle of a display or overlay
2719 2012-11-03 Chong Yidong <cyd@gnu.org>
2721 * process.c (wait_reading_process_output): Clean up the last
2724 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2726 * process.c (wait_reading_process_output): Avoid a race condition
2727 with SIGIO delivery (Bug#11536).
2729 2012-11-03 Chong Yidong <cyd@gnu.org>
2731 * buffer.c (cursor_type): Untabify docstring.
2733 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2735 * frame.h (struct frame): Drop can_have_scroll_bars member
2736 which is meaningless for a long time. Adjust comments.
2737 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2738 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2740 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2742 * window.c (decode_next_window_args): Update window arg after
2743 calling decode_live_window and so fix crash reported at
2744 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2745 by Juanma Barranquero <lekktu@gmail.com>.
2746 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2747 * font.c (Ffont_at): Likewise.
2749 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2751 * widget.c (resize_cb): New function.
2752 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2753 (EmacsFrameResize): Check if all is up to date before changing frame
2756 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2758 Implement backtrace output for fatal errors on MS-Windows.
2759 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2760 (BACKTRACE_LIMIT_MAX): New macro.
2761 (w32_backtrace): New function.
2762 (emacs_abort): Use w32_backtrace when the user chooses not to
2763 attach a debugger. Update the text of the abort dialog.
2765 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2767 Window-related stuff cleanup here and there.
2768 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2769 Use decode_any_window.
2770 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.

2777 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2778 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2781 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2783 Remove pad from struct input_event.
2784 * termhooks.h (struct input_event): Remove padding field.
2786 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2787 member is never cons for a long time. Adjust comment.
2788 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2789 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2790 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2791 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2793 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2795 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2797 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2799 Fix crash when using Emacs as commit editor for git (Bug#12697).
2800 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2801 and it is configured in conf_post.h.
2802 (Fcall_process): Don't invoke both setsid and setpgid; the former
2803 is enough, if it exists.
2804 * callproc.c (Fcall_process, child_setup):
2805 * process.c (create_process): Use setpgid.
2806 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2808 * dispnew.c (init_display): Initialize the foreground group
2809 if we are running a tty display.
2810 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2811 * lisp.h (init_foreground_group): New decl.
2812 * sysdep.c (inherited_pgroup): New static var.
2813 (init_foreground_group, tcsetpgrp_without_stopping)
2814 (narrow_foreground_group, widen_foreground_group): New functions.
2815 (init_sys_modes): Narrow foreground group.
2816 (reset_sys_modes): Widen foreground group.
2818 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2820 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2822 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2824 * minibuf.c (read_minibuf): Restore current buffer since
2825 choose_minibuf_frame calling Fset_frame_selected_window may
2826 change it (Bug#12766).
2828 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2830 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2832 2012-10-30 Kenichi Handa <handa@gnu.org>
2834 * font.c (Ffont_at): If WINDOW is specified and it is not
2835 displaying the current buffer, signal an error.
2837 2012-10-29 Daniel Colascione <dancol@dancol.org>
2839 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2840 In preparation for fixing bug#12739, move these functions from
2843 * coding.h, coding.c: ... to here, and compile them only when
2844 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2845 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2847 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2849 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2850 (timer_loop, getitimer, setitimer): Use it instead of
2851 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2853 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2856 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2858 * nsterm.m (NO_APPDEFINED_DATA): New define.
2859 (last_appdefined_event_data): New variable
2860 (last_appdefined_event): Remove.
2861 (ns_select): Initialize t from last_appdefined_event_data instead
2862 of [last_appdefined_event data1].
2863 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2864 remove last_appdefined_event (Bug#12698).
2866 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2868 * frame.c (x_set_font): Catch internal error.
2870 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2872 Avoid overflow in w32 implementation of interval timers.
2873 When possible, for ITIMER_PROF count only times the main thread
2875 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2876 'volatile ULONGLONG' types. All the other data which was
2877 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2878 (GetThreadTimes_Proc): New typedef.
2879 (w32_get_timer_time): New function, returns a suitable time value
2881 (timer_loop): Enter critical section when accessing ULONGLONG
2882 values of the itimer_data struct, as these accesses are no longer
2883 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2884 Remove unused variable.
2885 (init_timers): Initialize s_pfn_Get_Thread_Times.
2886 (start_timer_thread): Don't assign itimer->caller_thread here.
2887 (getitimer): Assign itimer->caller_thread here.
2888 (setitimer): Always call getitimer to get the value of ticks_now.
2889 (sys_spawnve): Avoid compiler warning about format mismatch.
2891 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2893 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2894 mouse movement events if the menu bar is active. This avoids
2895 producing a busy "hour-glass" cursor by Windows if the mouse
2896 pointer is positioned over a tooltip shown for some menu item.
2898 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2900 Don't assume process IDs fit in int.
2901 * emacs.c (shut_down_emacs) [!DOS_NT]:
2902 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2903 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2904 Use pid_t, not int, to store process IDs, as 'int'
2905 is not wide enough on a few platforms (e.g., AIX and IRIX).
2907 2012-10-23 Kenichi Handa <handa@gnu.org>
2909 The following change is to make face-font-rescale-alist work
2910 correctly for non-ASCII fonts.
2912 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2913 (font_open_for_lface): Handle Vface_font_rescale_alist.
2915 2012-10-23 Chong Yidong <cyd@gnu.org>
2917 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2919 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2923 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2925 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2928 2012-10-21 Glenn Morris <rgm@gnu.org>
2930 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2932 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2934 Port to OpenBSD 5.1.
2935 * frame.c (Fmouse_position, Fmouse_pixel_position):
2936 * xdisp.c (produce_stretch_glyph):
2937 Declare local vars only when they're needed.
2938 This is clearer and avoids a warning on OpenBSD about unused vars.
2939 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2940 This is safer, and avoids OpenBSD warnings about unused vars.
2941 * keyboard.c (record_menu_key): Remove unnecessary decl.
2942 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2943 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2944 as our definition clashes with OpenBSD's.
2945 * xfaces.c (load_face_colors, check_lface_attrs)
2946 (get_lface_attributes_no_remap, get_lface_attributes)
2947 (lface_fully_specified_p, x_supports_face_attributes_p)
2948 (tty_supports_face_attributes_p, face_fontset, realize_face)
2949 (realize_x_face, realize_tty_face):
2950 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2951 merely Lisp_Object *. This is more informative and avoids
2952 a warning on OpenBSD about accessing beyond an object's size.
2954 2012-10-20 Chong Yidong <cyd@gnu.org>
2956 * lread.c (Fload): Doc fix (Bug#12592).
2958 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2960 * font.c (Ffont_at): Fix previous change.
2962 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2964 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2965 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

2982 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2983 (staticpro): If we run out of staticpro slots, die with an
2984 informative error instead of just calling emacs_abort.
2986 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2988 Fix two flaws reported by Dmitry Antipov.

3207 keyboard.c, keymap.c: Use bool for booleans.

3243 since unsigned is guaranteed to have that behavior and signed is not.
3244 (read_char): Use ptrdiff_t for string length.
3245 (get_input_pending): Remove first argument, since it was always
3246 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3247 and behave as if it had that value. Return new value of
3248 input_pending. All callers changed.
3249 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3250 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3277 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3279 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3281 * commands.h (immediate_quit): Remove duplicate decl.
3283 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3285 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3288 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3290 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3292 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3293 match what GetLastError returns. Explain why the function is
3296 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3297 'is_tooltip_frame', to avoid confusion with its global namesake.
3299 2012-10-08 Daniel Colascione <dancol@dancol.org>
3301 * xdisp.c (start_hourglass): Call w32_note_current_window when
3302 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3303 build that caused Emacs to display the hourglass cursor forever.
3305 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3306 which is broken under remote desktop, calculate the number of
3307 colors available for a display based on the display's number of
3308 planes and number of bits per pixel per plane. (bug#10397).
3310 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3312 * nsfont.m (Vfonts_in_cache): New variable.
3313 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3314 are used. Add cached fonts to Vfonts_in_cache.
3315 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3317 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3319 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3321 (FONT_H): Define after FRAME_H.
3322 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3323 Update dependencies.
3325 * w32term.c: Remove leftover declaration of keyboard_codepage.
3327 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3329 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3330 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3331 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3332 (GLOBAL_SOURCES): Add cygw32.c.
3333 ($(BLD)/unexw32.$(O)):
3335 ($(BLD)/w32console.$(O)):
3336 ($(BLD)/w32fns.$(O)):
3337 ($(BLD)/w32heap.$(O)):
3338 ($(BLD)/w32menu.$(O)):
3339 ($(BLD)/w32proc.$(O)): Add w32common.h.
3341 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3343 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3345 2012-10-08 Daniel Colascione <dancol@dancol.org>
3347 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3348 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3349 accidental message numbering hole. Change other messages to
3352 * w32select.h (HAVE_W32SELECT): Remove.
3354 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3355 w32common.h instead of w32heap.h.
3357 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3358 (get_allocation_unit, get_processor_type, get_w32_major_version)
3359 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3360 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3361 (OS_NT, os_subtype, cache_system_info): Move declarations to
3364 * w32heap.c: Include w32common.h.
3365 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3366 (w32_minor_version, w32_build_number, w32_subtype):
3367 Remove duplicate definitions.
3369 * w32fns.c: Include w32common.h; include w32heap.h only in
3372 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3373 Use `report_file_error' instead of `error' in order to better
3374 inform users of what went wrong. Increase NTGUI_UNICODE file
3375 dialog box file name length to 32k, the maximum allowed by the NT
3378 * w32common.h: New file.
3379 (ROUND_UP, ROUND_DOWN, get_page_size)
3380 (get_allocation_unit, get_processor_type, get_w32_major_version)
3381 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3382 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3383 (OS_NT, os_subtype, cache_system_info): Move here.
3385 * unexw32.c, unexcw.c: Include w32common.h.
3387 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3388 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3389 to call syms_of_w32select.
3391 * cygw32.h: Remove obsolete EXFUN declarations.
3393 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3395 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3396 of w32inevt.o from SOME_MACHINE_OBJECTS.
3398 2012-10-08 Daniel Colascione <dancol@dancol.org>
3400 * image.c: Permanent fix for JPEG compilation issue --- limit
3401 jpeglib `boolean' redefinition to Cygwin builds.
3403 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3405 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3407 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3410 2012-10-08 Daniel Colascione <dancol@dancol.org>
3412 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3413 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3414 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3415 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3416 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3417 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3418 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3419 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3420 now a supported configuration.
3422 * Makefile.in: consolidate image variables into LIBIMAGE; add
3423 W32_OBJ and W32_LIBS. Compile new files.
3426 (_DebPrint) declare tracing facility for W32 debugging. We need
3427 to unify tracing later.
3429 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3430 unconditional use of W32 Unicode functions. Cygwin runs only on
3431 100% Unicode operating systems.
3433 * cygw32.c: New file. Define Cygwin-specific facilities.
3434 (Fcygwin_convert_path_to_windows)
3435 (Fcygwin_convert_path_from_windows): New user functions for
3436 accessing Cygwin path-munging routines.
3438 * cygw32.h: New file.
3439 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3440 UTF-16LE strings temporarily inside non-Lisp-visible string
3443 (w32_strerror): Just what it says on the tin.
3445 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3446 also run for Cygwin; both systems have the same problem with using
3447 GUI facilities in a forked child. Also call syms_of_cygw32,
3448 syms_of_w32select in correct places.
3450 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3451 needs fork-then-exec for daemon launching.
3453 * font.h: Include frame.h.
3455 * image.c: Use the image library cache machinery only when we're
3456 compiling for native WINDOWSNT; Cygwin can use shared libraries
3457 like any other Unixlike system.
3459 * keyboard.c: Clarify a comment regarding the input loop.
3461 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3462 functions directly instead of trying to detect at runtime that our
3463 host operating system supports them. We make this change for two
3464 reasons: Cygwin lacks support for the multibyte character
3465 conversion functions used by the legacy menu code, and Cygwin
3466 never needs to rely on non-Unicode APIs.
3468 * unexw32.c (hinst): Declare extern.
3470 * w32.c: Change header order;
3471 (w32_strerror): Move to w32fns.c because we need it for
3472 non-WINDOWSNT builds.
3474 * w32.h: Add #error macro to make sure we don't include w32.h for
3475 Cygwin builds. Remove w32select declarations.
3477 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3478 w32fns.c. w32console.c is WINDOWSNT-only.
3480 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3481 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3483 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3484 (w32_major_version, w32_minor_version, w32_build_number)
3485 (os_subtype, sound_type): Define here
3486 (w32_defined_color): Make color parameter const for consistency
3487 with other _defined_color functions.
3488 (w32_createwindow): Unconditionally call w32_init_class instead of
3489 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3490 through the code is complex and unnecessary because class
3491 registration is practically free.
3492 (w32_name_of_message): New EMACSDEBUG-only function.
3493 (Fset_message_beep): Move here
3494 (Fx_open_connection): Require that the display name for Windows be
3495 "w32" for consistency, emacsclient disambiguation, and maybe, one
3496 day, multi-window-system support.
3497 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3498 Cygwin files for W32 GUI facilities, since these clearly don't
3499 expect Cygwin names.
3500 (_DebPrint): Define.
3501 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3502 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3503 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3504 (w32_last_error): Remove.
3506 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3508 * w32heap.c (syspage_mask): Declare here.
3509 (cache_system_info): Remove.
3511 * w32inevt.c (faked_key): Define globally, not statically.
3512 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3513 (w32_console_toggle_lock_key): Move to w32fns.c.
3515 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3517 * w32proc.c (_DebPrint): Move to w32fns.c.
3518 * w32select.c: Include string.h, stdio.h for Cygwin.
3519 * w32select.h: New File.
3521 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3523 (w32_message_fd): New variable. Under Cygwin, holds the file
3524 descriptor the system used to tell us about pending thread
3527 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3528 that prevented compilation under non-WINDOWSNT systems.
3530 (w32_initialize): Open /dev/windows and assign it to
3531 w32_message_fd. Provide w32 feature.
3533 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3534 (WM_EMACS_INPUT_READY): add.
3535 (prepend_msg, w32_message_fd): Declare globally.
3538 (keyboard_handle): Use only when WINDOWSNT.
3539 (notify_msg_ready): New function. Posts a message to the main
3540 thread's message queue under CYGWIN, which wakes up the main
3541 thread from select(2) by making the /dev/windows file descriptor
3542 ready. Under WINDOWSNT, it sets an event the same way the old
3545 (post, prepend_msg): Actually call notify_msg_ready instead of
3546 setting the input event directly.
3548 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3550 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3551 but it still has blocs in it, don't return it to the system,
3552 instead of aborting. (Bug#12402)
3554 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3556 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3558 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3559 MAC_OS_X_VERSION_10_6.
3560 (syms_of_nsterm): Remove comment about Panther and above for
3562 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3563 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3564 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3566 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3567 MAC_OS_X_VERSION_10_4.
3569 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3570 MAC_OS_X_VERSION_10_2.
3572 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3574 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3575 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3577 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3578 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3579 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3580 Remove ns_in_resize check.
3581 (ns_clear_frame_area): Remove resize handle code.
3583 * nsfns.m (ns_in_resize): Remove.
3584 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3585 Remove ns_in_resize check.
3587 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3589 Improve sys_siglist detection.
3590 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3591 defined as a macro, as is done in Solaris.
3592 (sys_siglist_entries): New macro.
3593 (save_strsignal): Use it.
3594 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3595 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3597 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3599 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3600 fullscreen/Fullscreen.
3602 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3603 tobar_height is new.
3605 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3606 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3607 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3608 (windowDidResize:): Check for correct window if old style fullscreen.
3609 Capitalize word in comment. Remove incorrect comment.
3610 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3611 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3612 error in drawing background.
3613 (toggleFullScreen:): Remove comment. Rearrange calls.
3614 Set toolbar values to zero, save old height in tobar_height.
3615 Restore tool bar height when leaving fullscreen.
3616 (canBecomeMainWindow): New function.
3618 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3620 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3622 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3624 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3626 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3627 that time stamps of directories could also be changed.
3628 Don't request the too broad GENERIC_WRITE, only the more restrictive
3629 FILE_WRITE_ATTRIBUTES access rights.
3631 * fileio.c (Fset_file_times): Special-case ignoring errors for
3632 directories only on MSDOS, not on MS-Windows.
3634 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3636 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3638 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3640 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3641 see whether CreateFile failed.
3643 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3645 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3646 to avoid similar races.
3647 * keyboard.c (pending_signals): Now bool, not int.
3649 Port timers to OpenBSD, plus check for timer failures.
3650 OpenBSD problem reported by Han Boetes.
3651 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3653 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3654 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3655 like OpenBSD, which has timer_settime but does not declare it.
3656 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3657 whether to use itimerspec-related primitives. All uses of
3658 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3660 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3662 * profiler.c (handle_profiler_signal): Fix a malloc race
3663 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3665 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3667 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3669 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3671 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3672 consistent with the change in return value of 'safe_strsignal'.
3674 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3676 Prefer plain 'static' to 'static inline' (Bug#12541).
3677 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3678 (bidi_set_sor_type, bidi_push_embedding_level)
3679 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3680 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3681 (bidi_cache_search, bidi_cache_ensure_space)
3682 (bidi_cache_iterator_state, bidi_cache_find)
3683 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3684 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3685 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3686 Now 'static', not 'static inline'.
3688 Count overruns when profiling; change units to ns.
3689 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3690 Give extra weight to samples after overruns, to attempt to count
3691 the time more accurately.
3692 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3693 the underlying primitives nominally do ns.
3694 (Fprofiler_cpu_start): Document the change. Mention that
3695 the sampling intervals are only approximate.
3697 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3699 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3701 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3702 case for the special 0 coding-system.
3704 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3705 (Fmake_overlay): Remove redundant tests.
3706 (fix_start_end_in_overlays): Remove redundant recentering.
3708 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3710 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3711 Update dependencies.
3713 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3715 Fix a malloc race condition involving strsignal.
3716 A signal can arrive in the middle of a malloc, and Emacs's signal
3717 handler can invoke strsignal, which can invoke malloc, which is
3718 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3719 Fix it by altering the signal handler so that it does not invoke
3721 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3722 * process.c (status_message): Use const pointer, in case strsignal
3723 is #defined to safe_strsignal.
3724 * sysdep.c (sys_siglist, init_signals): Always define and
3725 initialize a substitute sys_siglist if the system does not define
3726 one, even if HAVE_STRSIGNAL.
3727 (safe_strsignal): Rename from strsignal. Always define,
3728 using sys_siglist. Return a const pointer.
3729 * syssignal.h (safe_strsignal): New decl.
3730 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3732 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3734 * w32proc.c (timer_loop): Fix code that waits for timer
3735 expiration, to avoid high CPU usage.
3737 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3739 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3740 (sweep_weak_table): Remove redundant prototypes.
3742 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3744 * emacs.c: Move the inclusion of TERM_HEADER after including
3745 windows.h on WINDOWSNT. This avoids compilation problems with
3748 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3750 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3751 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3752 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3753 as the previous version used 'void *'.
3755 * ralloc.c (ROUNDUP): Fix last change.
3756 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3759 * w32proc.c <disable_itimers>: New static flag.
3760 (init_timers): Initialize it to zero, after creating the critical
3761 sections used by the timer threads.
3762 (term_timers): Set to 1 before deleting the critical sections.
3763 (getitimer, setitimer): If disable_itimers is non-zero, return an
3764 error indication without doing anything. Reported by Fabrice
3765 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3766 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3768 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3771 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3772 term_ntproc after all the other bookkeeping, to get timers working
3773 as long as possible.
3775 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3777 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3778 Suggested by Juri Linkov in
3779 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3781 Prefer plain 'static' to 'static inline' (Bug#12541).
3782 With static functions, modern compilers inline pretty well by
3783 themselves; advice from programmers often hurts as much as it helps.
3784 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3785 this change shrinks the text size of the Emacs executable by 1.1%
3786 without affecting CPU significantly in my benchmark.
3787 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3866 (bidi_copy_it): Do the whole copy with a single memcpy.
3867 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3869 Revert the FOLLOW-SYMLINKS change for file-attributes.
3870 Doing it right would require several changes to Tramp, and there's
3871 not enough time to get that tested before the freeze today.
3872 * dired.c (directory_files_internal, Ffile_attributes):
3875 * frame.c (x_report_frame_params): Port better to wider ints.
3876 Do not assume that EMACS_UINT is the same width as uprintmax_t,

3914 * vm-limit.c (lim_data): Now size_t.
3915 (check_memory_limits): Adjust prototypes of real_morecore and

4069 Profiler improvements: more-accurate timers, overflow checks.
4070 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4071 signal.h, setjmp.h. Include systime.h instead.
4072 (saturated_add): New function.

4079 All uses changed to store the new value.
4080 (handle_profiler_signal): Rename from sigprof_handler_1,
4081 for consistency with other handlers. Do not check whether
4082 cpu_log is a hash-table if garbage collecting, since it
4083 doesn't matter in that case.

4085 for consistency with other handlers.
4086 (setup_cpu_timer): New function, with much of what used to be in
4087 Fprofiler_cpu_start. Check for out-of-range argument.
4088 Prefer timer_settime if available, and prefer
4089 thread cputime clocks, then process cputime clocks, then
4090 monotonic clocks, to the old realtime clock. Use make_timeval
4091 to round more-correctly when falling back to setitimer.
4092 (Fprofiler_cpu_start): Use it.
4093 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4094 Don't assume that passing NULL as the 2nd argument of setitimer
4095 is the same as passing a pointer to all-zero storage.
4096 Ignore SIGPROF afterwards.
4097 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4098 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4099 non-fatal signal handlers. Ignore SIGPROF on startup.
4100 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4101 in profiler.c, since sysdep.c now uses it.
4103 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4159 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4160 Since this stuff is now private to charset.c, there's no need for
4161 a public macro and no need to inline by hand.

4192 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4194 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4196 Prefer POSIX timers if available.
4197 They avoid a race if the timer is too close to the current time.
4198 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4199 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4200 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4202 2012-09-25 Eli Zaretskii <eliz@gnu.org>

4207 STRING_CHAR_ADVANCE.
4209 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4211 Move Vlibrary_cache to emacs.c and reset before dumping.
4213 * lisp.h (reset_image_types): Declare.
4214 [WINDOWSNT] (Vlibrary_cache): Declare.
4216 * image.c (reset_image_types): New function.
4218 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

4225 * w32.h (Vlibrary_cache): Do not declare.
4227 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4229 * w32proc.c (sys_signal): Handle all signals defined by the
4230 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4231 handlers for signals supported by Windows. Don't override
4232 term_ntproc as the handler for SIGABRT.
4233 (sigaction): Rewrite to call sys_signal instead of duplicating its
4235 (sys_kill): Improve commentary.
4237 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4238 consistency with a signature of a signal handler. All callers
4240 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4241 install term_ntproc as a signal handler for SIGABRT, as that
4242 should be done by the dumped Emacs.
4244 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4246 * w32select.c (term_w32select): Protect against repeated
4247 invocation by setting clipboard_owner to NULL after calling

4251 and term_ntproc to their modified signatures.
4253 * character.c (char_string, string_char): Remove calls to
4254 MAYBE_UNIFY_CHAR. See the discussion starting at
4255 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4258 2012-09-25 Chong Yidong <cyd@gnu.org>
4260 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4262 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4264 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4265 when encountering an unknown bytecode.
4267 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4269 image.c, indent.c: Use bool for booleans.
4270 * dispextern.h (struct image_type): Members valid_p, load, init
4271 now return bool, not int. All uses changed.
4272 * image.c: Omit unnecessary static decls.
4273 (x_create_bitmap_mask, x_build_heuristic_mask):
4274 Return void, not int, since callers don't care about the return value.

4303 Use bool for booleans.
4305 2012-09-24 Chong Yidong <cyd@gnu.org>
4307 * chartab.c (Fset_char_table_default): Obsolete function removed.
4309 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4311 Move pid_t related decls out of lisp.h.
4312 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4313 (interruptible_wait_for_termination):
4314 Move these decls from lisp.h to syswait.h, since they use pid_t.
4315 Needed on FreeBSD; see Herbert J. Skuhra in
4316 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4317 * callproc.c: Include syswait.h.

4334 * nsmenu.m (ns_update_menubar):
4335 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4336 * xfns.c (Fx_show_tip) [USE_GTK]:
4337 Use bool for boolean.
4338 * gtkutil.c (xg_update_frame_menubar):
4339 * xmenu.c (update_frame_menubar):
4340 Return void, not int, since caller ignores return value.
4341 * gtkutil.c (xg_change_toolbar_position):
4344 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4346 * makefile.w32-in (BLOCKINPUT_H): Remove.

4363 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4365 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4366 fatal_error_backtrace.
4368 * w32proc.c (sys_kill): Undo last change: don't do anything when
4369 invoked to deliver SIGABRT to our own process. This is now
4370 handled by emacs_raise.
4372 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4374 * w32term.c (w32_read_socket): Remove leftover reference to
4375 interrupt_input_pending.
4377 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4379 Do not use SA_NODEFER.
4380 Problem reported by Dani Moncayo in
4381 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4383 * sysdep.c (emacs_abort): Do not reset signal handler.
4384 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4385 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4386 wanted even on POSIXish hosts, and it doesn't work on Windows.
4388 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4390 * xterm.c (x_term_init): Call fixup_locale before and after calling
4391 gtk_init (Bug#12392).
4393 2012-09-23 Chong Yidong <cyd@gnu.org>
4395 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4396 Vdynamic_library_alist.
4398 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4399 (Fgnutls_available_p): Caller changed.
4401 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4402 (Flibxml_parse_xml_region): Likewise.
4404 * dispextern.h (struct image_type): Remove arg from init function.
4406 * image.c (Finit_image_library, lookup_image_type)
4407 (define_image_type): Remove now-unneeded second arg.
4408 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4409 (init_tiff_functions, init_gif_functions, init_svg_functions):
4410 Arglist and w32_delayed_load calling convention changed.
4411 (gs_type): Remove init_gs_functions; there is no such function.
4412 (valid_image_p, make_image): Fix caller to lookup_image_type.
4414 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4416 Simplify and avoid signal-handling races (Bug#12471).
4418 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4419 Avoid recursive loop if there's a fatal error in the function itself.
4420 * atimer.c (pending_atimers):
4421 * blockinput.h: Don't include "atimer.h"; no longer needed.
4422 (interrupt_input_pending): Remove. All uses removed.
4423 pending_signals now counts both atimers and ordinary interrupts.
4424 This is less racy than having three separate pending-signal flags.
4425 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4427 Rename from their upper-case counterparts BLOCK_INPUT,
4428 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4429 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4430 This makes it easier to access volatile variables more accurately.
4431 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4432 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4433 that's more reliable if the code is buggy and sets
4434 interrupt_input_blocked to a negative value. All uses changed.
4435 * atimer.c (deliver_alarm_signal):
4436 Remove. No need to deliver this to the parent; any thread can
4437 handle this signal now. All uses replaced by underlying handler.
4438 * atimer.c (turn_on_atimers):
4439 * dispnew.c (handle_window_change_signal):
4440 * emacs.c (handle_danger_signal):
4441 * keyboard.c (kbd_buffer_get_event):
4442 Don't reestablish signal handler; not needed with sigaction.
4443 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4445 Rework to avoid unnecessary accesses to volatile variables.
4446 (UNBLOCK_INPUT_TO): Now a function.
4447 (totally_unblock_input, unblock_input): New decls.
4448 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4449 (init_data): Remove. Necessary stuff now done in init_signal.
4450 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4451 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4452 (fatal_error_code): Remove; no longer needed.
4453 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4454 it doesn't always backtrace. All uses changed. No need to reset
4455 signal to default, since sigaction and/or die does that for us now.
4456 Use emacs_raise (FOO), not kill (getpid (), FOO).
4457 (main): Check more-accurately whether we're dumping.
4458 Move fatal-error setup to sysdep.c
4459 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4460 * gtkutil.c (xg_get_file_name, xg_get_font):
4461 Remove no-longer-needed signal-mask manipulation.
4462 * keyboard.c, process.c (POLL_FOR_INPUT):
4463 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4464 * keyboard.c (read_avail_input): Remove.
4465 All uses replaced by gobble_input.
4466 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4467 (kbd_buffer_store_event_hold, gobble_input):
4468 (record_asynch_buffer_change) [USABLE_SIGIO]:
4469 (store_user_signal_events):
4470 No need to mess with signal mask.
4471 (gobble_input): If blocking input and there are terminals, simply
4472 set pending_signals to 1 and return. All hooks changed to not
4473 worry about whether input is blocked.
4474 (process_pending_signals): Clear pending_signals before processing
4475 them, in case a signal comes in while we're processing.
4476 By convention callers now test pending_signals before calling us.
4477 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4478 New functions, to support changes to blockinput.h.
4479 (handle_input_available_signal): Now extern.
4480 (reinvoke_input_signal): Remove. All uses replaced by
4482 (quit_count): Now volatile, since a signal handler uses it.
4483 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4484 All callers changed. Block SIGINT only if not already blocked.
4485 Clear sigmask reliably, even if Fsignal returns, which it can.
4486 Omit unnecessary accesses to volatile var.
4487 (quit_throw_to_read_char): No need to restore sigmask.
4488 * keyboard.c (gobble_input, handle_user_signal):
4489 * process.c (wait_reading_process_output):
4490 Call signal-handling code rather than killing ourselves.
4491 * lisp.h: Include <float.h>, for...
4492 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4493 (pending_signals): Now volatile.
4494 (syms_of_data): Now const if IEEE floating point.
4495 (handle_input_available_signal) [USABLE_SIGIO]:
4496 (terminate_due_to_signal, record_child_status_change): New decls.
4497 * process.c (create_process): Avoid disaster if memory is exhausted
4498 while we're processing a vfork, by tightening the critical section
4500 (send_process_frame, process_sent_to, handle_pipe_signal)
4501 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4503 (send_process): No need for setjmp/longjmp any more, since the
4504 SIGPIPE stuff is now gone. Instead, report an error if errno
4506 (record_child_status_change): Now extern. PID and W are now args.
4507 Return void, not bool. All callers changed.
4508 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4509 Remove. All uses removed. This bug should be fixed now in a
4511 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4512 and record the child status change directly. This avoids the
4513 need to futz with the signal mask.
4514 (process_fatal_action): Move here from emacs.c.
4515 (emacs_sigaction_flags): New function, containing
4516 much of what used to be in emacs_sigaction_init.
4517 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4518 caught by emacs, to make races less likely.
4519 (deliver_process_signal): Rename from handle_on_main_thread.
4521 (BACKTRACE_LIMIT_MAX): Now at top level.
4522 (thread_backtrace_buffer, threadback_backtrace_pointers):
4524 (deliver_thread_signal, deliver_fatal_thread_signal):
4525 New functions, for more-accurate delivery of thread-specific signals.
4526 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4527 (deliver_arith_signal): Handle in this thread, not
4528 in the main thread, since it's triggered by this thread.
4529 (maybe_fatal_sig): New function.
4530 (init_signals): New arg DUMPING so that we can be more accurate
4531 about whether we're dumping. Caller changed.
4532 Treat thread-specific signals differently from process-general signals.
4533 Block all signals while handling fatal error; that's safer.
4534 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4536 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4537 Ignore SIGPIPE unless batch.
4538 (emacs_backtrace): Output backtrace for the appropriate thread,
4539 which is not necessarily the main thread.
4540 * syssignal.h: Include <stdbool.h>.
4541 (emacs_raise): New macro.
4542 * xterm.c (x_connection_signal): Remove; no longer needed
4543 now that we use sigaction.
4544 (x_connection_closed): No need to mess with sigmask now.
4545 (x_initialize): No need to reset SIGPIPE handler here, since
4546 init_signals does this for us now.
4548 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4550 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4551 background rect may be larger (Bug#12245).
4553 2012-09-23 Chong Yidong <cyd@gnu.org>
4555 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4557 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4559 * .gdbinit: Just stop at fatal_error_backtrace.
4560 See Stefan Monnier's request in
4561 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4562 Remove no-longer-used query of system type.
4564 2012-09-22 Chong Yidong <cyd@gnu.org>
4566 * search.c (Freplace_match): Doc fix (Bug#12325).
4568 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4570 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4571 (Fline_end_position): Doc fix.
4573 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4575 2012-09-22 Chong Yidong <cyd@gnu.org>
4577 * dispextern.h (struct image_type): Add new slot, storing a type
4578 initialization function.
4580 * image.c (define_image_type): Call the image initializer function
4581 if it is defined. Arguments and return value changed.
4582 (valid_image_p, make_image): Callers changed.
4583 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4584 (gif_type, imagemagick_type, svg_type, gs_type):
4585 Add initialization functions.
4586 (Finit_image_library): Call lookup_image_type.
4587 (CHECK_LIB_AVAILABLE): Macro deleted.
4588 (lookup_image_type): Call define_image_type here, rather than via
4589 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4590 (syms_of_image): Move define_image_type calls for xbm_type and
4591 pbm_type to lookup_image_type.

4595 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4596 'idle_timers' from here ...
4597 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4598 lists, to avoid infloops when the timer does something stupid,
4599 like reinvoke itself with the same or smaller time-out.
4602 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4604 * window.c (Fsplit_window_internal): Handle only Qt value of
4605 Vwindow_combination_limit separately.
4606 (Qtemp_buffer_resize): New symbol.
4607 (Vwindow_combination_limit): New default value.
4610 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4612 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4613 the new overlay string. (Bug#10159)
4615 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4617 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4618 or that fprintf is async-signal-safe. POSIX doesn't require
4621 2012-09-22 Chong Yidong <cyd@gnu.org>
4623 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4626 2012-09-22 Kenichi Handa <handa@gnu.org>
4628 * composite.c (composition_reseat_it): Handle the case that a
4629 grapheme cluster is not covered by a single font (Bug#12352).
4631 2012-09-21 Chong Yidong <cyd@gnu.org>
4633 * image.c (define_image_type): Avoid adding duplicate types to
4634 image_types (Bug#12463). Suggested by Jörg Walter.
4636 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4638 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4639 (print_load_command_name): Add case LC_DATA_IN_CODE.
4640 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4642 2012-09-21 Glenn Morris <rgm@gnu.org>
4644 * eval.c (Frun_hook_with_args_until_success)
4645 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4647 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4649 * fileio.c (Ffile_selinux_context): Only call freecon when
4650 lgetfilecon succeeded.
4651 (Fset_file_selinux_context): Likewise. (Bug#12444)
4653 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4655 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4656 reordering, locate the cursor by calling set_cursor_from_row; if
4657 that fails, clear the desired glyph matrix before returning a
4658 failure indication to the caller. Fixes leaving garbled display
4659 when fast scrolling with a down-key. (Bug#12403)
4660 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4661 scrolling through multibyte text.
4663 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4665 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4666 calling mark_vectorlike since that's the one that marks the window.
4667 (mark_discard_killed_buffers): Mark the final cdr.
4668 * window.h (struct window): Move prev/next_buffers to the
4669 non-standard fields.
4670 * window.c (make_window): Initialize prev/next_buffers manually.
4672 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4674 Omit unused arg EXPECTED from socket hooks.
4675 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4676 * nsterm.m (ns_term_init):
4677 * termhooks.h (struct terminal.read_socket_hook):
4678 * w32inevt.c (w32_console_read_socket):
4679 * w32term.c (w32_read_socket):
4680 * xterm.c (XTread_socket):
4681 Omit unused arg EXPECTED. All callers changed.
4682 (store_user_signal_events): Return void, not int, since callers no
4683 longer care about the return value. All uses changed.
4685 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4687 * w32gui.h (XParseGeometry): Do not declare.
4689 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4691 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4692 Ignore 'expected'. See Eli Zaretskii in
4693 <http://bugs.gnu.org/12471#8> (last line).
4695 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4696 (XParseGeometry): Now static. Substitute extremal values for
4697 values that are out of range.
4699 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4701 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4703 * nsfns.m (XParseGeometry): Remove.
4704 (Fx_create_frame): Call x_set_offset to correctly interpret
4705 top_pos in geometry.
4707 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4708 (Fx_parse_geometry): If there is a space in string, call
4709 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4711 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4713 * search.c (scan_buffer): Use character positions in calls to
4714 region_cache_forward and region_cache_backward, not byte
4715 positions. (Bug#12196)
4717 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4718 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4720 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4721 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4722 emacs_blocked_malloc, now deleted.
4724 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4726 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4727 The workaround was for improving performance on Solaris 2.4, but
4728 is getting in the way now. Emacs will still work if someone is
4729 still running Solaris 2.4 in a museum somewhere; Sun dropped
4730 support for Solaris 2.4 in 2003.
4731 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4732 * process.c (create_process) [HAVE_WORKING_VFORK]:
4733 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4734 since Emacs no longer uses vfork on that platform.
4736 2012-09-17 Glenn Morris <rgm@gnu.org>
4738 * emacs.c: Use COPYRIGHT.
4740 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4742 Remove configure's --without-sync-input option (Bug#12450).
4743 When auditing signal-handling in preparation for cleaning it up,
4744 I found that SYNC_INPUT has race conditions and would be a real
4745 pain to fix. Since it's an undocumented and deprecated
4746 configure-time option, now seems like a good time to remove it.
4747 Also see <http://bugs.gnu.org/11080#16>.
4748 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4749 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4750 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4751 (malloc_hysteresis):
4752 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4753 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4754 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4755 (dont_register_blocks, bytes_used_when_reconsidered)
4756 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4757 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4758 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4759 Remove. All uses removed.
4760 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4761 implementation, one that depends on whether the new macro
4762 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4764 * atimer.c (run_timers, handle_alarm_signal):
4765 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4766 (handle_async_input, process_pending_signals)
4767 (handle_input_available_signal, init_keyboard):
4768 * nsterm.m (ns_read_socket):
4769 * process.c (wait_reading_process_output):
4770 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4771 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4773 * xterm.c (XTread_socket):
4775 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4776 * eval.c (handling_signal): Remove. All uses removed.
4777 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4778 All uses replaced with the SYNC_INPUT version.
4779 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4781 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4784 * font.c (Ffont_shape_gstring): Remove unused local.
4786 2012-09-16 Glenn Morris <rgm@gnu.org>
4788 * Makefile.in (clean): No longer run nextstep's clean.
4790 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4792 (ns-app): Move here from ns.mk, and simplify.
4793 (clean): Simplify nextstep entry.
4794 * ns.mk: Remove file.
4796 2012-09-17 Kenichi Handa <handa@gnu.org>
4798 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4799 not covert the last few charactes.
4801 2012-09-16 Kenichi Handa <handa@gnu.org>
4803 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4804 here, but just check the validity of glyphs in the glyph-string.
4806 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4808 * window.c (Fwindow_parameter, Fset_window_parameter):
4809 Accept any window as argument (Bug#12452).
4811 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4813 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4814 to ns_term_init to avoid memory leak.
4816 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4817 explicit retain/release.
4818 (ns_term_init): Only allow one display. Initialize outerpool and
4821 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4823 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4824 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4825 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4826 the Microsoft problem in a different way, by altering ../nt/config.nt.
4828 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4843 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4844 by lisp.h. This completes removal of setjmp.h inclusion
4845 erroneously announced in the previous commit. (Bug#12446)
4847 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4850 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4851 not defined as a macro. The latter happens on MS-Windows.
4854 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4856 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4857 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4858 Some instances of '#include <setjmp.h>' removed, if the
4859 only reason for the instance was because "lisp.h" was included.
4860 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4861 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4862 and _longjmp with the new symbols. Emacs already uses _setjmp if
4863 available, so this change affects only POSIXish hosts that have
4864 sigsetjmp but not _setjmp, such as some versions of Solaris and
4865 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4866 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4867 (png_load_body) [HAVE_PNG]:
4868 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4869 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4870 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4871 since PNG requires jmp_buf. This is the only exception to the
4872 general rule that we now use sys_setjmp and sys_longjmp.
4873 This exception is OK since this code does not change the signal
4874 mask or longjmp out of a signal handler.
4876 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4878 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4879 Include "syssignal.h", for 'main_thread'.
4881 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4883 Avoid out-of-range marker position (Bug#12426).
4884 * insdel.c (replace_range, replace_range_2):
4885 Adjust markers before overlays, as suggested by comments.
4886 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4887 Remove redundant check before calling offset_intervals.
4889 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4891 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4892 current buffer (Bug#12387).
4894 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4896 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4898 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4900 Use a more backwards-compatible timer format (Bug#12430).
4901 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4902 vector element, not from the 4th, since PSECS is now at the end.
4903 (Fcurrent_idle_time): Doc fix.
4905 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4907 Function to mark objects and remove killed buffers at once.
4908 * alloc.c (discard_killed_buffers): Rename to ...
4909 (mark_discard_killed buffers) ... new name. Add marking
4910 of remaining objects. Fix comment. Adjust users.
4911 (mark_object): Do not touch frame buffer lists here.
4912 * frame.c (delete_frame): Reset frame buffer lists here.
4914 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4916 Better workaround for GNOME bug when --enable-gcc-warnings.
4917 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4918 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4919 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4921 Simplify SIGIO usage (Bug#12408).
4922 The code that dealt with SIGIO was crufty and confusing, e.g., it
4923 played tricks like "#undef SIGIO" but these tricks were not used
4924 consistently. Simplify mostly by not #undeffing standard symbols,
4925 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4926 or not as we please) rather than "defined SIGIO" (standard symbol
4927 that we probably shouldn't #undef).
4928 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4929 Modules that need it can include it.
4930 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4931 * dispextern.h (ignore_sigio): New decl.
4932 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4933 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4934 * emacs.c (shut_down_emacs):
4935 * keyboard.c (kbd_buffer_store_event_hold):
4936 Use ignore_sigio rather than invoking 'signal' directly.
4937 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4939 (FIONREAD, SIGIO): Do not #undef.
4940 (tty_read_avail_input): Use #error rather than a syntax error.
4941 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4942 for I_PIPE, used by SETUP_SLAVE_PTY.
4943 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4944 * sysdep.c (croak): Remove; no longer needed. This bit of
4945 temporary code, with Fred N. Fish's comment that it's temporary,
4946 has been in Emacs since at least 1992!
4947 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4948 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4949 * syssignal.h (croak): Remove decl.
4950 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4951 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4952 now that we're termios-only.
4953 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4954 * term.c (dissociate_if_controlling_tty): Use #error rather than
4957 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4958 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4959 to work around GNOME bug 683906.
4960 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4961 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4962 This works around GCC bug 54561.
4964 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4966 More fixes for 'volatile' and setjmp/longjmp.
4967 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4968 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4969 (png_load_body) [HAVE_PNG]:
4970 (jpeg_load_body) [HAVE_JPEG]:
4971 New function, with most of the old parent function's body.
4972 (png_load) [HAVE_PNG]:
4973 (jpeg_load) [HAVE_JPEG]:
4974 Invoke the new function, to avoid longjmp munging our locals.
4975 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4976 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4977 longjmp is passed 2, as the C standard doesn't guarantee this.
4978 Instead, store the failure code into mgr->failure_code.
4980 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4982 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4983 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4984 (syms_of_keyboard): Remove support for unread-command-char.
4986 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4988 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4989 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4990 violation. (Bug#12426)
4992 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4994 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4996 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4998 * eval.c: Add `inhibit-debugger'.
4999 (Qinhibit_debugger): New symbol.
5000 (call_debugger): Bind it instead of Qdebug_on_error.
5001 (maybe_call_debugger): Test Vinhibit_debugger.
5002 (syms_of_eval): Define inhibit-debugger.
5003 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5004 (syms_of_xdisp): Remove inhibit-debug-on-message.
5006 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5008 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5009 If a nonvolatile local variable is written before a _longjmp to
5010 the frame containing the variable, and is read after the _longjmp,
5011 the value read is indeterminate. Some local variables of type
5012 'struct handler' and 'struct catchtag' are used in this way, so
5013 mark each of their slots as volatile if the slot can be set before
5014 _longjmp and read afterwards.
5015 * lisp.h (struct handler): var and chosen_clause are now volatile.
5016 (struct catchtag): val, next, and pdlcount are now volatile.
5018 * bidi.c (bidi_push_it, bidi_pop_it):
5019 * fns.c (copy_hash_table):
5020 * image.c (define_image_type):
5021 * keyboard.c (kbd_buffer_store_event_hold):
5022 * process.c (Fprocess_send_eof):
5023 * xfaces.c (x_create_gc) [HAVE_NS]:
5024 * xgselect.c (xg_select):
5025 Prefer assignment to memcpy when either will do.
5027 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5028 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5029 time an item is removed. No need to mark this function 'inline';
5030 the compiler knows better than we do.
5032 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5034 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5035 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5036 to change_frame_size (Bug#12388).
5037 (windowDidResize:): Pass YES to updateFrameSize.
5039 * nsterm.h: Add delay parameter to updateFrameSize.
5041 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5043 Discard killed buffers from deleted window and frame objects.
5044 This reduces an amount of references to killed buffers and
5045 helps GC to reclaim them faster.
5046 * alloc.c (discard_killed_buffers): New function.
5047 (mark_object): Use it for deleted windows and frames.
5048 (mark_object): If symbol's value is set up for a killed buffer
5049 or deleted frame, restore its global binding.
5050 * data.c (swap_in_global_binding): Add GC notice.
5051 (swap_in_symval_forwarding): Use convenient set_blv_where.
5052 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5053 * window.h: ... to here.
5055 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5057 Convenient macro to check whether the buffer is live.
5058 * buffer.h (BUFFER_LIVE_P): New macro.
5059 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5060 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5062 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5064 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5065 composition cases (Bug#12364).
5067 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5068 overhang of succeeding glyphs overlapping box cursor.
5070 * w32term.c (x_draw_glyph_string): Likewise.
5072 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5074 Simplify, document, and port floating-point (Bug#12381).
5075 The porting part of this patch fixes bugs on non-IEEE platforms
5076 with frexp, ldexp, logb.
5077 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5079 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5080 support, by removing commented-out code and briefly listing the
5081 C89 functions excluded. The commented-out stuff was confusing
5082 maintenance, e.g., we thought we needed cbrt but it was commented out.
5083 (logb): Remove decl; no longer needed.
5084 (isfinite): New macro, if not already supplied.
5085 (isnan): Don't replace any existing macro.
5086 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5087 are present on all C89 platforms.
5088 (Ffrexp): Do not special-case zero, as frexp does the right thing
5090 (Flogb): Do not use logb, as it doesn't have the desired meaning
5091 on hosts that use non-base-2 floating point. Instead, stick with
5092 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5093 frexp, to avoid getting an unspecified result.
5095 * xdisp.c (Qinhibit_debug_on_message): Now static.
5097 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5099 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5100 NSBezierPath (Bug#12131).
5102 2012-09-10 Chong Yidong <cyd@gnu.org>
5104 * fns.c (Fdelq, Fdelete): Doc fix.
5106 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5108 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5109 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5111 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5113 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5114 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5117 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5119 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5120 left fringe if the window has a left margin. This avoids leaving
5121 traces of the cursor because its leftmost pixel is not drawn over.
5123 * dispnew.c (update_window_line): When the left margin area of a
5124 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5125 that screen line. (Bug#12277)
5127 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5129 Assume C89 or later for math functions (Bug#12381).
5130 This simplifies the code, and makes it a bit smaller and faster,
5131 and (most important) makes it easier to clean up signal handling
5132 since we can stop worring about floating-point exceptions in
5133 library code. That was a problem before C89, but the problem
5134 went away many years ago on all practical Emacs targets.
5135 * data.c, image.c, lread.c, print.c:
5136 Don't include <math.h>; no longer needed.
5137 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5138 might be autoconfigured, as that never happens.
5140 * doprnt.c (DBL_MAX_10_EXP):
5141 * print.c (DBL_DIG):
5142 Remove. C89 or later always defines these.
5143 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5144 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5145 (arith_error, domain_error, domain_error2):
5146 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5147 no longer needed -- we simply return what C returns. All uses removed.
5148 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5150 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5151 Remove. All uses expanded, as these macros are no longer used
5152 more than once and are now more trouble than they're worth.
5153 (Ftan): Use tan, not sin / cos.
5154 (Flogb): Assume C89 frexp.
5155 (fmod_float): Assume C89 fmod.
5156 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5157 (init_floatfns): Remove. All uses removed.
5159 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5161 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5162 compositeToPoint for OSX < 10.6 (Bug#12390).
5164 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5166 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5167 This produces more-accurate results.
5169 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5171 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5172 changes (Bug#12088).
5174 2012-09-08 Chong Yidong <cyd@gnu.org>
5176 * syntax.c (Fstring_to_syntax): Doc fix.
5178 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5180 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5181 in the internal border.
5182 (x_set_window_size): Remove static variables and their usage.
5183 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5184 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5185 Remove fringe/internal border adjustment (Bug#11052).
5186 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5187 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5188 (ns_fix_rect_ibw): Remove.
5189 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5190 (ns_dumpglyphs_box_or_relief): Ditto.
5191 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5193 (ns_dumpglyphs_image): Ditto.
5194 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5196 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5197 their usage. Add fringe_extended_p and its use as in other terms.
5198 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5199 scroll bar was removed.
5200 (updateFrameSize): New function.
5201 (windowDidResize): Move code to updateFrameSize and call it.
5203 * nsterm.h (EmacsView): Add updateFrameSize.
5205 2012-09-07 Chong Yidong <cyd@gnu.org>
5207 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5209 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5211 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5213 More signal-handler cleanup (Bug#12327).
5214 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5215 Problem introduced when merging patches. Noted by Eli Zaretskii in
5216 <http://bugs.gnu.org/12327#67>.
5217 * floatfns.c: Comment fix.
5218 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5219 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5220 and anyway the declaration is harmless even if SIGDANGER is not defined.
5221 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5222 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5223 source files not surprisingly expected syssignal.h to define, or
5224 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5225 Include <sys/ioctl.h>, for FIONREAD.
5226 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5227 This eliminates a problem whereby other files mysteriously had
5228 to include "syssignal.h" before including "systty.h" if they
5229 wanted to use "#ifdef SIGIO".
5231 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5233 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5235 * w32.c (sigemptyset): Empty the set.
5236 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5238 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5240 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5242 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5243 (mark_object): Likewise for frame objects.
5245 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5247 * syssignal.h (handle_on_main_thread): Always declare,
5248 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5249 This ports to platforms without HAVE_PTHREAD.
5251 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5253 Signal-handler cleanup (Bug#12327).
5254 Emacs's signal handlers were written in the old 4.2BSD style with
5255 sigblock and sigmask and so forth, and this led to some
5256 inefficiencies and confusion. Rewrite these to use
5257 pthread_sigmask etc. without copying signal sets around. Also,
5258 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5259 'signal', and instead use functions that do not attempt to take
5260 over the system name space. This patch causes Emacs's text
5261 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5262 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5263 Do not include <signal.h> or "syssignal.h", as these
5264 modules do not use signals.
5265 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5266 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5267 Do not include <signal.h>, as "syssignal.h" does that for us now.
5268 * atimer.c (sigmask_atimers): New function.
5269 (block_atimers, unblock_atimers): New functions,
5270 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5272 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5273 no longer needed here.
5274 * emacs.c (main): Inspect existing signal handler with sigaction,
5275 so that there's no need to block and unblock SIGHUP.
5276 * sysdep.c (struct save_signal): New member 'action', replacing
5277 old member 'handler'.
5278 (save_signal_handlers, restore_signal_handlers):
5279 Use sigaction instead of 'signal' to save and restore.
5280 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5281 New function. All users of 'signal' modified to use set_sighandler
5282 if they're writeonly, and to use sys_signal if they're read+write.
5283 (emacs_sigaction_init, forwarded_signal): New functions.
5284 (sys_signal): Remove. All uses replaced by calls to sigaction
5285 and emacs_sigaction_init, or by direct calls to 'signal'.
5286 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5287 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5288 all uses replaced by pthread_sigmask etc. calls.
5289 * syssignal.h: Include <signal.h>.
5290 (emacs_sigaction_init, forwarded_signal): New decls.
5291 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5292 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5293 (sigmask, sys_sigmask): Remove; no longer needed.
5294 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5295 (sigblock, sigunblock, sigfree):
5296 (sigsetmask) [!defined sigsetmask]:
5297 Remove. All uses replaced by pthread_sigmask.
5298 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5299 no longer need to be replaced, and its typical old uses
5300 are now done via emacs_sigaction_init and sigaction.
5301 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5302 (sys_sigdel): Remove; unused.
5303 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5305 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5307 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5308 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5310 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5312 Explicitly mark buffer_defaults and buffer_local_symbols.
5313 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5314 mark_local_symbols here.
5315 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5316 since special buffers aren't marked here any more.
5317 (allocate_buffer): Chain new buffer with all_buffers here...
5318 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5320 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5321 (syms_of_buffer): Remove staticpro of the above.
5322 (init_buffer_once): Set names for buffer_defaults and
5323 buffer_local_symbols.
5325 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5327 Use bool for booleans in font-related modules.
5328 * font.c (font_intern_prop, font_style_to_value)
5329 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5330 (generate_otf_features, font_check_otf_features, font_check_otf)
5331 (font_match_p, font_list_entities, font_at):
5332 * fontset.c (fontset_id_valid_p, reorder_font_vector
5333 (fontset_find_font, Fset_fontset_font)
5334 (face_suitable_for_char_p) [0]:
5335 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5336 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5337 (m17n_flt_initialized, ftfont_shape_by_flt):
5338 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5339 * nsfont.m (nsfont_draw):
5340 * w32font.c (w32font_draw):
5341 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5342 Use bool for booleans.
5343 * font.h: Adjust to above API changes.
5344 (struct font, struct font_driver, struct font_driver_list):
5345 Use bool for booleans.
5346 (struct font): Remove useless member encoding_type.
5348 * fontset.c, xftfont.c: Omit unnecessary static decls.
5350 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5352 * alloc.c (mark_object): Revert window marking code
5353 since it's unsafe for the Fset_window_configuration.
5355 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5357 Fix race conditions with signal handlers and errno (Bug#12327).
5358 Be more systematic about preserving errno whenever a signal
5359 handler returns, even if it's not in the main thread. Do this by
5360 renaming signal handlers to distinguish between signal delivery
5361 and signal handling. All uses changed.
5362 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5363 * data.c (deliver_arith_signal): Rename from arith_error.
5364 * dispnew.c (deliver_window_change_signal): Rename from
5365 window_change_signal.
5366 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5367 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5368 * keyboard.c (deliver_input_available_signal): Rename from
5369 input_available_signal.
5370 (deliver_user_signal): Rename from handle_user_signal.
5371 (deliver_interrupt_signal): Rename from interrupt_signal.
5372 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5373 (deliver_child_signal): Rename from sigchld_handler.
5374 * atimer.c (handle_alarm_signal):
5375 * data.c (handle_arith_signal):
5376 * dispnew.c (handle_window_change_signal):
5377 * emacs.c (handle_fatal_signal, handle_danger_signal):
5378 * keyboard.c (handle_input_available_signal):
5379 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5380 * process.c (handle_pipe_signal, handle_child_signal):
5381 New functions, with the actual signal-handling code taken from the
5382 original respective signal handlers, sans the sporadic attempts to
5383 preserve errno, since that's now done by handle_on_main_thread.
5384 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5385 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5386 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5388 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5389 Move initialization of main_thread to sysdep.c's init_signals.
5390 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5391 our usage, and simplifies the mainline code.
5392 (record_child_status_change): New static function, as a helper
5393 for handle_child_signal, and with most of the old child handler's
5395 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5396 (handle_child_signal): Use the above.
5397 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5398 Moved here from emacs.c.
5399 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5400 code moved here from emacs.c's main function.
5401 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5402 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5403 This lets callers save and restore errno properly.
5405 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5407 Remove redundant or unused things here and there.
5408 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5409 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5410 * editfns.c (Fcompare_buffer_substrings): Likewise.
5411 * frame.h (struct terminal, struct font_driver_list):
5412 Remove redundant declarations.
5413 * window.h (Qleft, Qright): Likewise.
5415 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5417 Do not mark objects from deleted buffers, windows and frames.
5418 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5419 (mark_object): Likewise for windows and frames.
5421 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5423 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5424 buffer_defaults and buffer_local_symbols as valid objects.
5425 Return special value to denote them.
5427 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5429 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5430 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5431 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5432 (file_name_absolute_p, Fsubstitute_in_file_name):
5433 (check_executable, check_writable, Ffile_accessible_directory_p)

5435 (Finsert_file_contents, choose_write_coding_system)
5436 (Fwrite_region, build_annotations, a_write, e_write)
5438 * filelock.c (boot_time_initialized, get_boot_time)
5439 (get_boot_time_1, lock_file_1, within_one_second):
5440 * floatfns.c (in_float):
5441 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5442 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5443 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5444 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5445 * window.c (compare_window_configurations):
5446 Use bool for booleans.
5447 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5448 (Fdefault_file_modes): Now mode_t, not int, for modes.
5449 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5450 (internal_delete_file): Now returns void, not a (boolean) int,
5451 since nobody was looking at the return value.
5452 * lisp.h, window.h: Adjust to above API changes.
5454 * xdisp.c (set_message): Simplify and reindent last change.
5456 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5458 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5460 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5462 * eval.c (call_debugger): Make the function non-static so that we
5463 can call it from set_message.
5465 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5466 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5468 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5470 Give more-useful info on a fatal error (Bug#12328).
5471 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5472 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5473 of doing the work ourselves.
5474 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5475 do most of the work.
5476 (fatal_error_backtrace): New function, taken from the guts
5477 of the old fatal_error_signal, but with a new option to output
5479 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5480 info about the signal than just its number.
5481 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5482 * sysdep.c: Include <execinfo.h>
5483 (emacs_backtrace): New function, taken partly from the previous
5484 code of the 'die' function.
5485 (emacs_abort): Call fatal_error_backtrace rather than abort.
5487 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5489 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5490 eager (load-time) macro-expansion.
5491 * lisp.mk (lisp): Add macroexp.
5493 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5495 Simplify redefinition of 'abort' (Bug#12316).
5496 Do not try to redefine the 'abort' function. Instead, redo
5497 the code so that it calls 'emacs_abort' rather than 'abort'.
5498 This removes the need for the NO_ABORT configure-time macro
5499 and makes it easier to change the abort code to do a backtrace.
5500 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5501 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5502 Remove; sysdep.c's emacs_abort now takes its place.
5503 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5504 'abort' changed to use 'emacs_abort'.
5505 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5506 (abort) [!defined abort]: Rename to ...
5507 (emacs_abort): ... new name.
5508 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5509 the place of the old 'abort' in emacs.c.
5510 * w32.c, w32fns.c (abort): Do not #undef.
5511 * w32.c (emacs_abort): Rename from w32_abort.
5513 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5515 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5516 offsets[j].dv, since the y axis of the screen coordinates points
5517 down, while the y axis of the font definition coordinates points
5518 up. This fixes display of Arabic diacritics such as KASRA and
5519 KASRATAN. (Bug#11860)
5521 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5523 Be more systematic about _setjmp vs setjmp.
5524 * alloc.c (test_setjmp, mark_stack):
5525 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5526 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5527 (png_load, my_error_exit, jpeg_load):
5528 * process.c (send_process_trap, send_process):
5529 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5530 The underscored versions are up to 30x faster on some hosts.
5531 Formerly, the code used setjmp+longjmp sometimes and
5532 _setjmp+_longjmp at other times, with no particular reason to
5533 prefer setjmp+longjmp.
5535 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5537 Fix minor problem found by static checking.
5538 * buffer.c (Fdelete_all_overlays): Return nil.
5540 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5542 * buffer.c (Fdelete_all_overlays): New function.
5544 2012-09-03 Chong Yidong <cyd@gnu.org>
5546 * gtkutil.c: Add extern decl for Qxft.
5548 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5564 EXCLUDE_SUBRS_P. All callers changed.
5565 * dispextern.h, lisp.h: Reflect above API changes.
5566 * firstfile.c (dummy): Use the address of 'main', whose signature
5567 won't change, instead of the address of 'initialize', whose
5568 signature just changed from int to bool.
5569 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5570 * msdos.c (fatal_error_in_progress): ... from here.
5571 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5573 (redisplay_internal, unwind_redisplay): Simply clear
5574 REDISPLAYING_P when unwinding, instead of saving its previous,
5575 always-false value and then restoring it.
5577 Clean up some extern decls.
5578 Mostly, this hoists extern decls out of .c files and into .h files.
5579 That way, we're more likely to catch errors if the interfaces change.
5580 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5581 declare xg_mark_data.
5582 * dispextern.h (x_frame_parm_handlers):
5584 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

5600 * xfont.c (x_clear_errors):
5601 * xterm.c (x_frame_parm_handlers):
5602 Remove now-redundant extern decls.
5603 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5604 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5606 * xfaces.c: Remove unnecessary static decls.
5607 * xterm.c (updating_frame): Remove decl of nonexistent object.
5609 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5610 when building globals.h, as the objects that are not built on
5611 this host are not needed to compile C files on this host.
5613 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5615 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5653 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5655 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5663 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5665 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5666 more than one grapheme cluster passed to the shaper: compute the
5667 offset adjustment values separately for each cluster. (Bug#11860)
5669 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5670 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5671 about implicit conversions from integer to pointer.
5673 2012-09-01 Daniel Colascione <dancol@dancol.org>
5675 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5676 system used too early.
5678 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5680 Better seed support for (random).

5729 window system declarations.
5731 * frame.h: Move common functions here: set_frame_menubar,
5732 x_set_window_size, x_sync, x_get_focus_frame,
5733 x_set_mouse_position, x_set_mouse_pixel_position,
5734 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5758 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5760 Remove mark_ttys function and fix tty_display_info initialization.
5761 * lisp.h (mark_ttys): Remove prototype.
5762 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5763 to mark_ttys because all possible values of 'top_frame' slot are
5764 the frames which are reachable from Vframe_list.
5765 * term.c (mark_ttys): Remove.
5766 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5768 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

5795 * lread.c (init_lread): For out-of-tree builds, only add the
5796 source directory's site-lisp dir to the load-path if it exists,
5797 consistent with in-tree builds. (Bug#12302)
5799 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

5818 Handle click on close button as quit.
5820 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5821 Add window_closed and button_values. Add void as return value for
5822 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5823 Add process_dialog as new member.
5825 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5827 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5935 * composite.h, lisp.h: Reflect above API changes.
5937 * cmds.c, coding.c: Use bool for booleans.
5938 * cmds.c (move_point, Fself_insert_command):
5939 * coding.h (struct composition status, struct coding_system):
5940 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
5941 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
5942 (emacs_mule_char, decode_coding_emacs_mule)

5956 (Funencodable_char_position, code_convert_region)
5957 (code_convert_string, code_convert_string_norecord)
5958 (Fset_coding_system_priority):
5959 * fileio.c (Finsert_file_contents):
5960 Use bool for booleans.
5961 * coding.h, lisp.h: Reflect above API changes.
5962 * coding.c: Remove unnecessary static function decls.
5963 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5964 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5965 not a boolean 'int', since callers never look at the return value.
5966 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5967 * coding.h (decoding_buffer_size, encoding_buffer_size)
5968 (emacs_mule_string_char): Remove unused extern decls.
5969 (struct iso_2022_spec, struct coding_system):
5970 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5971 (struct emacs_mule_spec): Remove unused field 'full_support'.
5972 All initializations removed.
5973 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5975 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5977 Fix spare memory change (Bug#12286).
5978 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5979 (valid_lisp_object_p): Likewise.
5981 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5983 * window.c (Fset_window_configuration): Record any window's old
5984 buffer if it's replaced (see Bug#8789). If the new current
5985 buffer doesn't appear in the selected window, go to its old
5988 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5990 Special MEM_TYPE_SPARE to denote reserved memory.
5991 * alloc.c (enum mem_type): New memory type.
5992 (refill_memory_reserve): Use new type for spare memory.
5993 This prevents live_cons_p and live_string_p from incorrect
5994 detection of uninitialized objects from spare memory as live.
5996 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5999 * Makefile.in (.PHONY): versioclean -> versionclean.
6001 Remove unused external symbols.
6002 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6003 * window.c (Qwindow_valid_p, decode_valid_window):
6004 Now static, not extern.
6005 * data.c (Qinterval): Remove; unused.
6006 (syms_of_data): Do not define 'interval'.
6007 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6008 * window.h (decode_valid_window):
6011 * character.c, charset.c, chartab.c: Use bool for booleans.
6012 * character.c (lisp_string_width, string_count_byte8)
6013 (string_escape_byte8):
6014 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6015 (load_charset_map_from_file, map_charset_chars)
6016 (Fdefine_charset_internal, define_charset_internal)
6017 (Fdeclare_equiv_charset, find_charsets_in_text)
6018 (Ffind_charset_region, char_charset, Fiso_charset):
6019 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6020 (sub_char_table_set, sub_char_table_set_range)
6021 (char_table_set_range, optimize_sub_char_table)
6022 (map_sub_char_table):
6023 Use bool for boolean.
6024 * character.c (str_to_unibyte): Omit last boolean argument; it was
6025 always 0. All callers changed.
6026 * character.h, charset.h: Adjust to match previous changes.
6027 * character.h (char_printable_p): Remove decl of nonexistent function.
6028 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6029 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6030 are all boolean, so make them single-bit bitfields.
6032 * lisp.h (ASET): Remove attempt to detect side effects.
6033 It was meant to be temporary and it often doesn't work,
6034 because when IDX has side effects the behavior of IDX==IDX
6035 is undefined. See Stefan Monnier in
6036 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6038 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6040 * lisp.h (functionp): New function (extracted from Ffunctionp).
6041 (FUNCTIONP): Use it.
6042 * eval.c (Ffunctionp): Use it.
6044 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6046 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6047 as that's faster and simpler than static storage. Don't bother
6048 with the g_main_context_query overhead if g_main_context_pending
6049 says no events are pending.
6050 (gfds, gfds_size): Remove these static vars.
6051 (xgselect_initialize): Remove; no longer needed.
6052 All uses and decls removed.
6054 * emacs.c (fatal_error_signal_hook): Remove.
6055 All uses removed. This leftover from old code was always 0.
6057 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6058 * casefiddle.c (casify_object, casify_region):
6059 * casetab.c (set_case_table):
6060 * category.c, category.h (word_boundary_p):
6061 * category.h (CHAR_HAS_CATEGORY):
6062 Use bool for booleans, instead of int.
6064 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6066 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6068 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6070 On assertion failure, print backtrace if available.
6071 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6072 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6073 * Makefile.in (LIB_EXECINFO): New macro.
6076 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6077 * bytecode.c (exec_byte_code):
6078 * callint.c (check_mark, Fcall_interactively):
6079 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6080 (getenv_internal, sync_process_alive, call_process_exited):
6081 * lisp.h (USE_SAFE_ALLOCA):
6082 Use bool for booleans, instead of int.
6083 * lisp.h, process.h: Adjust prototypes to match above changes.
6084 * callint.c (Fcall_interactively): Don't assume the mark's
6085 offset fits in 'int'.
6087 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6089 * buffer.c, buffer.h: Use bool for boolean.
6090 * buffer.c (reset_buffer_local_variables)
6091 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6092 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6093 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6094 (overlay_touches_p, overlay_strings, Foverlay_put)
6095 (report_overlay_modification, call_overlay_mod_hooks):
6096 (mmap_enlarge, mmap_set_vars):
6097 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6098 Use bool for booleans, instead of int.
6099 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6100 since the 1-or-0 return value is always ignored anyway.
6101 (mmap_initialized_p):
6102 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6103 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6105 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6107 * bidi.c: Use bool for boolean.
6108 This is a bit more readable, and makes the text segment of bidi.o
6109 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6110 Presumably it's faster too.
6111 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6113 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6114 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6115 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6116 (bidi_explicit_dir_char, bidi_level_of_next_char)
6117 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6118 Use bool for booleans, instead of int.
6119 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6120 (bidi_unshelve_cache): Adjust decls to match code.
6122 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6124 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6127 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6129 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6130 * atimer.h: Include <stdbool.h>.
6132 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6134 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6135 compile time tests instead of run time tests on systems that do
6137 (FRAME_MAC_P): Remove leftover from deleted code.
6138 * frame.c (syms_of_frame): Remove leftover from deleted code.
6140 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6142 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6144 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6146 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6147 Otherwise, the compiler complains about (A?B:C) where B is void
6148 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6149 (fontset_add): Return void, for FONTSET_ADD.
6151 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6153 * alloc.c: Use bool for booleans.
6154 (gc_in_progress, abort_on_gc)
6155 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6156 (dont_register_blocks) [GC_MALLOC_CHECK]:
6157 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6158 (check_string_bytes, make_specified_string, memory_full)
6159 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6160 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6161 (mark_stack, valid_pointer_p, make_pure_string)
6162 (Fgarbage_collect, survives_gc_p, gc_sweep):
6163 Use bool for booleans, instead of int.
6164 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6165 Remove unused local.
6166 * alloc.c (PURE_POINTER_P):
6167 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6168 * editfns.c (Fformat):
6169 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6171 * fns.c (sweep_weak_table):
6172 * lisp.h (suppress_checking, push_message, survives_gc_p)
6173 (make_pure_string, gc_in_progress, abort_on_gc):
6174 * lread.c (readchar, read1):
6175 * print.c (Fprin1_to_string):
6176 * xdisp.c (push_message):
6177 Use bool for booleans affected directly or indirectly by
6180 Make recently-introduced setters macros.
6181 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6182 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6183 (set_fontset_default, set_fontset_fallback): Rename from their
6184 upper-case counterparts, and make them functions rather than macros.
6185 This is more consistent with the other recently-introduced setters.
6186 These don't need to be inline, since they're local.
6188 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6190 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6191 the loop (Bug#12247).
6193 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6195 * lisp.h (vcopy): Use memcpy rather than our own loop.
6196 This fixes a performance regression introduced by the recent
6197 addition of vcopy. This means 'vcopy' will need to be modified
6198 for a copying collector, but that's OK. Also, tighten the
6199 checking in the assertion.
6201 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6203 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6204 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6205 non-base glyph for the width of the base character, according to
6206 what x_draw_composite_glyph_string_foreground expects.
6207 Generate WADJUST value according to composition_gstring_width's
6208 expectations, to produce correct width of the composed character.
6209 Reverse the sign of the DU offset produced by ScriptPlace.
6211 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6213 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6215 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6217 Avoid direct writes to contents member of struct Lisp_Vector.
6218 * lisp.h (vcopy): New function to copy data into vector.
6219 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6220 * fns.c (Ffillarray): Use ASET.
6221 * keyboard.c (timer_check_2): Use AREF and ASET.
6222 (append_tool_bar_item, Frecent_keys): Use vcopy.
6223 * lread.c (read_vector): Use ASET.
6224 * msdos.c (Frecent_doskeys): Use vcopy.
6225 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6226 (Finternal_merge_in_global_face): Use ASET and vcopy.
6227 * xfont.c (xfont_list_pattern): Likewise.
6229 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6231 * window.c (Fwindow_point): For the selected window always return
6232 the position of its buffer's point.
6233 (Fset_window_point): For the selected window always go in its
6234 buffer to the specified position.
6236 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6238 Setter macros for fontsets.
6239 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6240 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6241 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6244 2012-08-20 Glenn Morris <rgm@gnu.org>
6246 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6247 Don't assume that `ln -f' works.
6249 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6251 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6252 and later about non-assignments with no effect. See discussion at
6253 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6256 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6258 Inline setter functions for Lisp_Objects slots of struct specbinding.
6259 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6262 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6264 * window.c (select_window): Always make selected window's buffer
6267 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6269 Use AREF and ASET for docstrings of category tables.
6270 * category.h (CATEGORY_DOCSTRING): Use AREF.
6271 (SET_CATEGORY_DOCSTRING): Use ASET.
6272 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6274 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6276 Inline setter functions for hash table members.
6277 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6278 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6279 (set_hash_key_and_value, set_hash_index, set_hash_next)
6280 (set_hash_hash): New functions.
6281 * charset.c, fns.c: Adjust users.
6283 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6285 Inline getter and setter functions for per-buffer values.
6286 * buffer.h (per_buffer_default, set_per_buffer_default)
6287 (per_buffer_value, set_per_buffer_value): New functions.
6288 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6289 * buffer.c, data.c: Adjust users.
6291 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6293 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6295 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6297 Rely on <config.h> + <unistd.h> to declare 'environ',
6298 as gnulib does this if the system doesn't.
6299 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6300 Remove declaration. MS-Windows declares it on stdlib.h which is
6301 included by conf_post.h.
6302 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6303 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6304 * vm-limit.c: Include <unistd.h>, for 'environ'.
6306 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6307 (start_of_data): Remove decl; mem-limits.h provides it.
6309 * xdisp.c (handle_invisible_prop): Make it a bit faster
6310 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6312 2012-08-19 Chong Yidong <cyd@gnu.org>
6314 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6317 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6319 * .gdbinit: Use call instead of set when calling a function in the
6322 * data.c (set_internal): Don't use set_blv_found.
6323 (Fkill_local_variable): Likewise.
6325 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6327 * nsfont.m (ns_ascii_average_width): Ensure the string
6328 ascii_printable is initialized with a null-terminated character
6329 array. Otherwise, it can contain undesired extra characters.
6331 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6333 port new setting code to Sun C 5.8 2005/10/13
6334 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6335 Return void, not Lisp_Object. Otherwise, the compiler
6336 complains about (A?B:C) where B is void and C is Lisp_Object
6337 when compiling CHAR_TABLE_SET, due to the recent change to
6338 the API of sub_char_table_set_contents.
6340 2012-08-18 Chong Yidong <cyd@gnu.org>
6342 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6343 for the string case (Bug#3874).
6345 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6347 * buffer.h (BSET): Remove (Bug#12215).
6348 Replace all uses with calls to new setter functions.

7279 Fix macroexp crash on Windows with debugging (Bug#12118).
7280 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7281 checking subscripts; problem introduced with the recent
7282 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7283 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7284 since it's used in non-static inline functions now.
7286 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

7313 (INLINE_HEADER_END): New macros.
7314 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7336 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7338 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7339 This how ASET and AREF are supposed to work, and makes
7340 it easier to think about future improvements. See
7341 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7342 * charset.h (set_charset_attr): New function.

7724 (w32_kbd_patch_key, key_event): Use the codepage returned by
7725 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
7726 (key_event): use uChar.UnicodeChar only if
7727 w32_console_unicode_input is non-zero.

7757 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7758 enumeration constants, as PURE and HEAP are too general, and clash
7759 with other headers and sources, such as gmalloc.c and the
7760 MS-Windows system headers. All users changed.
7762 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7764 Revert last save_excursion_save and save_excursion_restore changes.
7765 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7778 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7779 arms of an 'if', not using conditional expressions; otherwise GDB
7780 complains about the types in the unevaluated arm when the argument
7781 is an integer literal.
7782 (xgetint): Simplify expression.
7783 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7784 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7785 Zaretskii in <http://bugs.gnu.org/12036#13>.
7786 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7787 needed now that we have gdb_make_enums_visible.
7788 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7789 (enum enum_USE_LSB_TAG):
7790 New enum types, packaging up enums that need to be exported to GDB.

7814 * lisp.h (struct Lisp_Excursion): New data type.
7815 (PVEC_EXCURSION): New pseudovector type.
7816 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7817 to deal with it. Adjust comments.

7832 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7833 emacs.c, as this is a more-suitable home. Had this been done earlier
7834 the fix for 12036 would have avoided some of the problems noted in
7835 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7836 would have been more obvious.
7837 * emacs.c: Do not include <verify.h>; no longer needed.
7838 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7839 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7840 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

7845 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7846 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7847 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7848 not be usable in #if. This simplifies things.
7850 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7852 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7857 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7858 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7859 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7860 Adjust to changes in lisp.h and emacs.c, by using
7861 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7862 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7863 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7864 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7865 instead of gdb_valbits.
7866 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7867 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7868 instead of gdb_array_mark_flag.
7869 (xboolvector): Get size from $->size, not $->header.size.
7870 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7871 (xreload, hook-run, hookpost-run): Remove.
7872 * emacs.c: Include <verify.h>.
7873 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7874 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7876 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7877 (gdb_USE_LSB_TAG): New enum constants.
7878 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7879 Also define these as enum constants, so they're visible to GDB.
7880 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7881 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7882 as constants, so they're visible to GDB.

7885 Now enum constants, not macros, so they're visible to GDB.
7886 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7887 more convenient now. All uses changed.
7888 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7889 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7891 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7898 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7899 add argument, tune behavior, and adjust all callers.
7901 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7903 Use typedef for EMACS_INT, EMACS_UINT.
7904 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7905 than macros. This simplifies debugging in the usual case, since
7906 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7907 and it allows expressions involving EMACS_INT casts.
7908 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7910 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7920 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7922 Adjust buffer text indirection counters at the end of Fkill_buffer.
7923 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7924 buffer is definitely dead. This should really fix an issue reported
7925 by Christoph Scholtes again. (Bug#12007).
7926 (init_buffer_once): Initialize indirection counters of
7927 buffer_defaults and buffer_local_symbols (for sanity and safety).
7929 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7931 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7932 and continuation glyphs on tooltip frames, leave them at zero.

7935 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7937 Simplify copy_overlay.
7938 * buffer.c (copy_overlay): Simplify. Use build_marker.

7960 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7962 Swap buffer text indirection counters in Fbuffer_swap_text.
7963 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7964 This avoids crash reported by Christoph Scholtes at
7965 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7967 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7969 * nsmenu.m (Popdown_data): New struct.
7970 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7972 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7973 (initWithContentRect): Make imgView and contentView non-static
7974 and autorelease them. Also autorelease img and matrix (Bug#12005).
7975 (dealloc): Remove (Bug#12005).
7977 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7979 Adjust consing_since_gc when objects are explicitly freed.

7992 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7994 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7995 as it's limited by the amount of memory, not by INT_MAX.
7997 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7999 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8000 in special-event-map. See the discussion at

8059 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8060 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8061 Adjust users accordingly.

8081 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8082 'for_each_per_buffer_object_at'.
8083 All uses changed. It's better to use upper-case for macros that
8084 cannot be implemented as functions, to give the reader a clue
8085 that they're special.

8653 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
8654 since nothing has defined it on these platforms.

8670 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
8671 function attribute, so we only use it if it exists in the
8674 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
8676 Avoid call to strlen in fast_c_string_match_ignore_case.

8723 * s/aix4-2.h (unix): Remove; no longer needed.
8725 EMACS_TIME simplification (Bug#11875).
8726 This replaces macros (which typically do not work in GDB)
8727 with functions, typedefs and enums, making the code easier to debug.
8728 The functional style also makes code easier to read and maintain.
8729 * systime.h: Include <sys/time.h> on all hosts, not just if
8730 WINDOWSNT, since 'struct timeval' is needed in general.
8731 (EMACS_TIME): Now a typedef, not a macro.
8732 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8734 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

8738 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
8739 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8740 which are not functions. All uses rewritten to use:
8741 (make_emacs_time): New function.
8742 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8743 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8744 not functions. All uses rewritten to use the following, respectively:
8745 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8746 (add_emacs_time, sub_emacs_time): New functions.
8747 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8748 * fileio.c (Fcopy_file):
8749 * xterm.c (XTflash): Get the current time closer to when it's used.
8750 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8764 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8765 (menu_separator_name_p):
8766 * nsmenu.m (ns_update_menubar):
8767 Prefer memcmp to strncmp when either will do.
8768 * nsterm.m: Include <ftoastr.h>.
8770 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8771 Prefer snprintf to strncpy.
8772 * nsterm.m (ns_term_init):
8773 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8774 * nsterm.m (ns_term_init):
8775 Avoid the need for strncpy, by using build_string or
8776 make_unibyte_string directly. Use dtoastr, not snprintf.
8777 * process.c (Fmake_network_process): Diagnose service names that
8778 are too long, rather than silently truncating them or creating
8779 non-null-terminated names.
8780 (Fnetwork_interface_info): Likewise, for interface names.
8781 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8782 Prefer sprintf to strncat.
8783 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8784 Prefer vsnprintf to vsprintf + strncpy.
8786 2012-07-10 Glenn Morris <rgm@gnu.org>
8788 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8789 Clarify fallback case.
8791 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

8794 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8795 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8796 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8797 where argument type is known to be a Lisp_Cons.
8799 2012-07-10 Tom Tromey <tromey@redhat.com>
8801 * bytecode.c (BYTE_CODE_THREADED): New macro.

8809 Optimize pure C strings initialization.
8810 * lisp.h (make_pure_string): Fix prototype.
8811 (build_pure_c_string): New function, defined as static inline. This
8812 provides a better opportunity to optimize away calls to strlen when
8813 the function is called with compile-time constant argument.
8814 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8815 argument, adjust users accordingly. Use build_pure_c_string where
8817 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8818 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8819 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8821 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8823 Avoid calls to strlen in miscellaneous functions.
8824 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8825 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8826 * lread.c (openp): Likewise.
8828 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8830 Avoid calls to strlen in path processing functions.
8831 * fileio.c (file_name_as_directory): Add comment. Change to add
8832 srclen argument and return the length of result. Adjust users

8836 Adjust users accordingly.
8837 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8839 2012-07-10 Glenn Morris <rgm@gnu.org>

8846 * s/gnu.h (DATA_START): Move definitions to configure.
8848 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8849 We include usg5-4-common.h, which defines them both.
8851 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8852 O_RDONLY already includes it).
8854 Stop ns builds setting the EMACSLOADPATH environment variable.
8855 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8856 Now it does not set EMACSLOADPATH, just returns the load-path string.
8857 * nsterm.h: Update accordingly.
8858 * lread.c [HAVE_NS]: Include nsterm.h.
8859 (init_lread) [HAVE_NS]: Use ns_load_path.
8860 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8862 2012-07-09 Glenn Morris <rgm@gnu.org>
8864 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8865 since the included bsd-common.h does so.
8867 Stop ns builds setting the EMACSPATH environment variable.
8868 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8869 (ns_init_paths): Do not set EMACSPATH.
8870 * nsterm.h (ns_exec_path): Add it.
8871 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8874 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8876 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8878 * process.c (wait_reading_process_output): 'waitchannels' was unset
8879 when read_kbd || !NILP (wait_for_cell); fix this.
8881 Add GCC-style 'const' attribute to functions that can use it.
8882 * character.h (char_resolve_modifier_mask):
8883 * keyboard.h (make_ctrl_char):
8884 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8893 Add decls with ATTRIBUTE_CONST.
8895 Minor improvements to make_formatted_string.
8896 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8897 where int is good enough, as vsprintf returns an int.
8898 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8900 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8902 Use make_formatted_string to avoid double length calculation.
8903 * lisp.h (make_formatted_string): New prototype.
8904 * alloc.c (make_formatted_string): New function.
8905 * buffer.c (Fgenerate_new_buffer_name): Use it.

8909 * frame.c (make_terminal_frame, set_term_frame_name)
8910 (x_report_frame_params): Likewise.

8927 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8929 Move marker debugging code under MARKER_DEBUG.
8930 * marker.c (MARKER_DEBUG): Move marker debugging code under
8931 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8932 for bootstrap with --enable-checking (~3x slowdown reported
8933 by Juanma Barranquero <lekktu@gmail.com>).
8934 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8936 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8938 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8939 See <http://bugs.gnu.org/11825#29>.
8941 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8943 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8944 has no font, use the frame's font. (Bug#11813)
8945 (display_line): Add commentary about displaying truncation glyphs
8947 (produce_special_glyphs): Move here from term.c.
8949 * term.c (produce_special_glyphs): Move to xdisp.c.
8951 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8954 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8956 * xdisp.c (display_line): Avoid warning about implicit declaration
8959 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8961 * lisp.h: Remove empty conditional.
8963 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8965 * lread.c (load_path_check): Now static.
8967 Fix some minor --with-ns problems found by static checking.
8968 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8969 (x_set_font) [!HAVE_X_WINDOWS]:
8970 * image.c (xpm_load_image) [HAVE_NS]:
8971 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8972 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8973 Remove unused local.
8974 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8975 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8976 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8977 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8978 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8979 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8980 Fix pointer signedness problem.
8981 * xfaces.c (FRAME_X_FONT_TABLE):
8982 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8984 2012-07-07 Glenn Morris <rgm@gnu.org>
8986 * lread.c (load_path_check): New function, split from init_lread.
8987 (init_lread): Reorganize. Motivation:
8988 If EMACSLOADPATH is set, check/warn about that rather than the
8989 defaults, which we are not going to use. Hence we can remove
8990 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8991 Don't warn if site-lisp directories are missing.
8992 If not installed, start from a blank load-path, since
8993 PATH_LOADSEARCH refers to the eventual installation directories.
8995 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8997 Support truncation and continuation glyphs on GUI frames, when
8998 fringes are disabled. (Bug#11832)
8999 * xdisp.c (init_iterator): Get dimensions of truncation and
9000 continuation glyphs even if on GUI frames.
9001 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9002 or both, are absent.
9003 (start_display, move_it_in_display_line_to): Handle the case of a
9004 GUI frame without a fringe to display continuation or truncation
9006 (insert_left_trunc_glyphs): Support GUI frames: make sure
9007 truncation glyphs overwrite enough glyphs from the current line to
9008 have sufficient space in pixels.
9009 (display_line): Support truncation and continuation glyphs on GUI
9010 frames. If some spare pixels are left on the line after inserting
9011 the truncation glyphs, fill that space with a stretch glyph of a
9012 suitably computed width.
9014 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9015 produce_glyphs, to support GUI sessions.
9017 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9019 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9021 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9023 Do not require float-time's arg to fit in time_t (Bug#11825).
9024 This works better on hosts where time_t is unsigned, and where
9025 float-time is applied to the (negative) difference between two times.
9026 * editfns.c (decode_time_components): Last arg is now double *,
9027 not int *, and means to store all the result as a double, without
9028 worrying about whether the seconds part fits in time_t.
9029 All callers changed.
9030 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9031 All callers changed.
9032 (Ffloat_time): Do not fail merely because the specified time falls
9033 outside of time_t range.
9035 2012-07-07 Glenn Morris <rgm@gnu.org>

9077 * process.c: Avoid unnecessary calls to gettime.
9078 (wait_reading_process_output): Don't get the time of day
9079 when gobbling data immediately and not waiting, as there's no need
9080 for it in that case. This removes a FIXME.
9082 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9084 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9085 is defined (Bug#11768).

9095 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9097 Compile marker debugging code only if ENABLE_CHECKING is defined.
9098 * marker.c (byte_char_debug_check, count_markers):
9099 Use only if ENABLE_CHECKING is defined.
9100 (byte_debug_flag): Remove.
9101 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9102 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9104 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9106 Avoid code repetition in marker-related functions.

9144 Port to OpenBSD 5.1 amd64.
9145 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9146 This is needed for OpenBSD, and should be harmless on all BSD systems.
9147 Also, include <sys/sysctl.h>, as it should be available on all
9148 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9149 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9150 use p_pid member, not kp_proc.pid.
9152 2012-07-06 Glenn Morris <rgm@gnu.org>
9154 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9156 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9167 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9169 Omit needless casts involving void * pointers and allocation.
9170 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9171 as the former is more robust if P's type is changed.
9172 Prefer xzalloc to xmalloc + memset 0.
9173 Simplify malloc-or-realloc to realloc.
9174 Don't worry about xmalloc returning a null pointer.
9175 Prefer xstrdup to xmalloc + strcpy.
9176 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9178 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9179 alloca of a constant.

9183 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9184 hscroll is larger than the line width. Fixes long and futile
9185 looping inside extend_face_to_end_of_line (on a TTY) producing
9186 glyphs that are not needed and thrown away.
9188 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9190 * marker.c (set_marker_restricted_both): Simplify by using

9204 followed by gtk_box_set_homogeneous (Bug#11768).
9205 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9206 (update_theme_scrollbar_width, xg_create_scroll_bar):
9207 Use gtk_scrollbar_new (Bug#11768).
9208 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

9216 * xdisp.c (window_hscroll_limited): New function.
9217 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9218 coordinates when window's hscroll is set to insanely large
9221 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

9290 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9291 This should be fixed in a better way; see Eli Zaretskii in
9292 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9293 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9295 * fileio.c (time_error_value): Rename from special_mtime.
9296 The old name's problems were noted by Eli Zaretskii in
9297 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9299 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9300 This variable's comment says Emacs needs at least one GDB-visible
9301 symbol of type enum pvec_type, to work around GDB problems.
9302 The symbol's value doesn't matter.
9304 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9305 that causes compilation to fail on pre-C99 compilers.
9307 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9309 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9333 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9334 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9335 abusing vector->header.next.nbytes.
9336 (live_vector_p): Use PVEC_TYPE.
9337 (mark_object): Adapt code to extract pvectype. Use switch.
9339 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9341 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9342 Tighten new eassert a bit.
9344 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9346 Fix compilation with --enable-gcc-warnings and -O1
9348 * doprnt.c (doprnt): Change type of tem to int, initialize
9349 to avoid compiler warning. Add eassert.
9350 * search.c (simple_search): Initialize match_byte to avoid
9351 compiler warning. Add eassert.
9353 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9355 Avoid weird behavior with large horizontal scrolls.
9356 Without this change, for example, large hscroll values would
9357 mess up Emacs's display on Fedora 15 x86, presumably due to
9358 overflows in int calculations in the display code.
9359 Also, if buffers had long lines, Emacs would freeze.
9360 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9361 (set_window_hscroll): New function, containing the old guts of
9362 Fset_window_hscroll. Return the clipped value.
9363 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.

9375 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9376 since GCC 4.4.6 issues a bogus warning for them.
9378 Fix bugs in file timestamp newness comparisons.
9379 * fileio.c (Ffile_newer_than_file_p):
9380 * lread.c (Fload): Use full timestamp resolution of files,
9381 not just the 1-second resolution, so that files that are only
9382 slightly newer still count as newer.
9383 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9384 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9386 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9388 * fileio.c: Improve handling of file time marker. (Bug#11852)

9395 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9396 marker for non-existing file. (Bug#11852)
9398 2012-07-03 Glenn Morris <rgm@gnu.org>
9400 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9401 and did not make it into globals.h).
9403 2012-07-03 Tom Tromey <tromey@redhat.com>

9443 * lisp.h (Frandom): Make it visible to C.
9444 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new

9466 avoid calls to mallopt if zero_vector is returned.
9468 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9470 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9471 is enabled, avoid dereferencing NULL current_sblock if
9474 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9476 Cleanup basic buffer management.

9490 Lisp area of struct buffer.
9491 (mark_object): Use it. Adjust marking of misc objects
9492 and related comments.
9494 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9496 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9497 wrapper that is not needed because the wrapped code is a no-op (zero
9498 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9499 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9501 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9503 * alloc.c (mark_buffer): Simplify. Remove prototype.
9504 (mark_object): Add comment. Reorganize marking of vector-like
9505 objects. Use CHECK_LIVE for all vector-like objects except buffers
9506 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9507 Avoid redundant calls to mark_vectorlike for bool vectors.
9509 2012-06-30 Glenn Morris <rgm@gnu.org>
9511 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9513 * epaths.in (PATH_SITELOADSEARCH): New.
9514 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9515 This is rather than relying on --enable-locallisppath elements
9516 having "site-lisp" in their names. (Bug#10208#25, 11658)
9518 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9520 * w32proc.c (sys_select): Accept and ignore one more argument.
9522 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9524 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9525 (pselect) [!MS_DOS]: Redirect to sys_select.
9527 * sysdep.c: Don't include dos.h and dosfns.h.
9529 * process.c (sys_select):
9530 * msdos.c (sys_select): Accept one more argument and ignore it.
9532 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9533 adapt data types and code to that.
9536 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9537 which clashes with the gnulib function of the same name.
9539 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9541 * font.c (font_style_to_value, font_style_symbolic)
9542 (font_prop_validate_style): Add type checks for values in
9545 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9547 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9550 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9552 * xdisp.c (try_window_id): Undo last change.
9554 * w32.c (getwd): Adjust commentary about startup_dir.
9555 (init_environment): Always call sys_access, even in non-MSVC
9556 builds. Don't chdir to the directory of the Emacs executable.
9557 This undoes code from 1997 which was justified by the need to
9558 "avoid conflicts when removing and renaming directories". But its
9559 downside was that every relative file name was being interpreted
9560 relative to the directory of the Emacs executable, which can never
9561 be TRT. In particular, it broke sys_access when called with
9562 relative file names.
9563 (sys_access): Map GetLastError to errno.
9565 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9567 * window.h (struct window): Change type of 'fringes_outside_margins'
9568 to bitfield. Fix comment. Adjust users accordingly.
9569 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9571 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9574 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9576 * gnutls.c (emacs_gnutls_handshake):
9577 Add QUIT to make the loop interruptible.
9579 2012-06-29 Glenn Morris <rgm@gnu.org>
9581 * charset.c (init_charset): Make lack of etc/charsets fatal.
9583 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9585 * editfns.c (region_limit): Fix type mismatch.
9587 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9589 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9590 undefined. Convert from xassert to eassert.
9591 * nsmenu.m: Convert from xassert to eassert.
9592 * nsterm.m: Likewise.
9594 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9596 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9598 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9600 Avoid integer overflow on scroll-left and scroll-right.
9601 * window.c (HSCROLL_MAX): New macro.
9602 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9603 overflow when requested scroll falls outside ptrdiff_t range.
9605 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9607 * window.h (struct window): Change type of 'hscroll',
9608 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9609 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9610 Adjust users accordingly.
9611 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9612 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9613 from EMACS_INT to ptrdiff_t.
9614 (make_window): Omit redundant initialization.
9616 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9618 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9620 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9622 * window.h (struct window): Change type of 'use_time' and
9623 'sequence_number' from Lisp_Object to int.
9624 * frame.c (make_frame): Adjust users accordingly.
9625 * print.c (print_object): Likewise.
9626 * window.c (select_window, Fwindow_use_time, make_parent_window)
9627 (make_window): Likewise.
9629 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9631 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9632 enabled with --enable-checking=[all,glyphs] configure option.
9633 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9634 adjust comments accordingly.
9635 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
9636 undefined, adjust comments accordingly.

9681 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9683 * alloc.c (allocate_string_data): Remove dead code.
9684 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
9685 avoid GCC warning about unused macro.
9687 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9689 * alloc.c (allocate_string): Omit intervals initialization.
9690 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9691 as in make_pure_string and make_pure_c_string.
9693 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9695 * alloc.c (allocate_string): Fix last change.
9697 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9699 * alloc.c (allocate_string): Remove two redundant calls
9700 to memset, add explicit initialization where appropriate.
9702 2012-06-27 Glenn Morris <rgm@gnu.org>
9704 * lisp.mk (lisp): Remove paths.elc.
9706 2012-06-27 Chong Yidong <cyd@gnu.org>
9708 * doc.c (Fsubstitute_command_keys): Fix punctuation.
9710 2012-06-26 John Wiegley <johnw@newartisans.com>
9712 * unexmacosx.c (copy_data_segment): Add two section names used
9713 on Mac OS X Lion: __mod_init_func and __mod_term_func.
9715 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
9716 when building with Clang.
9718 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>
9720 * eval.c (Fapply): Allow calling it with a single argument.
9722 2012-06-26 Eli Zaretskii <eliz@gnu.org>
9724 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
9725 _stricmp and _strnicmp.
9726 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
9728 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9730 * alloc.c (allocate_window): Zero out non-Lisp part of newly
9732 (allocate_process): Likewise for new process.
9733 (allocate_terminal): Change to use offsetof.
9734 (allocate_frame): Likewise.
9735 * frame.c (make_frame): Omit redundant initialization.

9743 * term.c (delete_tty): Remove redundant call to memset.
9745 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9747 * alloc.c: Remove build_string.
9748 * lisp.h: Define build_string as static inline. This provides
9749 a better opportunity to optimize away calls to strlen when the
9750 function is called with compile-time constant argument.
9751 * image.c (imagemagick_error): Convert to build_string.
9752 * w32proc.c (sys_spawnve): Likewise.
9753 * xterm.c (x_term_init): Likewise.
9755 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9757 Use sprintf return value instead of invoking strlen on result.
9758 In the old days this wasn't portable, since some sprintf
9759 implementations returned char *. But they died out years ago and
9760 Emacs already assumes sprintf returns int.
9761 Similarly for float_to_string.
9762 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9763 * ccl.c (ccl_driver):
9764 * character.c (string_escape_byte8):
9765 * data.c (Fnumber_to_string):
9766 * doprnt.c (doprnt):
9767 * print.c (print_object):
9768 * xdisp.c (message_dolog):
9769 * xfns.c (syms_of_xfns):
9770 Use sprintf or float_to_string result to avoid need to call strlen.
9771 * data.c (Fnumber_to_string):
9772 Use make_unibyte_string, since the string must be ASCII.
9773 * lisp.h, print.c (float_to_string): Now returns int length.
9774 * term.c (produce_glyphless_glyph):
9775 Use sprintf result rather than recomputing it.
9777 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9778 * Makefile.in (ALL_CFLAGS):
9779 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9780 * gmalloc.c, regex.c: Include <config.h> unconditionally.
9782 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9784 * dispextern.h (xstrcasecmp): Define to library function
9785 strcasecmp if available.
9786 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
9788 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
9790 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):
9791 Avoid comma operator.

9801 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9803 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9804 sprintf already null-terminates its output.
9806 * xfns.c (x_window): Remove redundant cast.
9808 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9810 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9811 `const char *' to `char *' to avoid compiler warning.
9813 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9815 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9816 instead of truncating it to 63 (admittedly a generous limit).
9818 * process.c: Fix spelling and caps in comments.
9820 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9822 * emacs.c (setpgrp): Remove definition, unused.

9832 (SYSTIME_H): Add nt/inc/sys/time.h.
9834 * systime.h [WINDOWSNT]: Include sys/time.h.
9836 * s/ms-w32.h (struct timespec): Definition moved from
9837 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
9839 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

9866 Use _Noreturn rather than NO_RETURN.
9867 No need for separate decl merely because of _Noreturn.
9868 * sound.c (sound_warning, parse_sound):
9869 Remove unnecessary forward decls.
9871 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9873 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9874 * lisp.h (WAIT_READING_MAX): New macro.
9875 * dispnew.c (Fsleep_for, sit_for):
9876 * keyboard.c (kbd_buffer_get_event):
9877 * process.c (Faccept_process_output):
9878 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9879 This improves on the previous patch, which introduced a bug
9880 when time_t is unsigned and as wide as intmax_t.
9881 See <http://bugs.gnu.org/9000#51>.
9883 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9885 * dispnew.c (sit_for, Fsleep_for):
9886 * keyboard.c (kbd_buffer_get_event):
9887 * process.c (Faccept_process_output): Avoid compiler warnings when
9888 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
9890 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
9892 * makefile.w32-in: Update dependencies.
9894 * w32.c (ltime): Add return type and declare static.
9895 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
9897 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9899 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9900 Privately reported by Herbert J. Skuhra.
9901 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9903 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9904 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9906 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9908 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9909 last argument of make_unibyte_string.
9911 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9912 language ID in the event parameters.
9914 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9915 event.code, not the obscure "character set ID".
9917 2012-06-23 Chong Yidong <cyd@gnu.org>
9919 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9921 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9923 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
9924 * w32.c (fdutimens): New function.
9926 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
9928 * s/ms-w32.h (pselect): Redirect to sys_select.
9930 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
9932 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
9933 in the logic of incrementing and decrementing the value of
9934 use_relocatable_buffers.
9936 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9938 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9939 Privately reported by Herbert J. Skuhra.

9946 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9948 Support higher-resolution time stamps (Bug#9000).
9949 The time stamps are only nanosecond-resolution at the C level,
9950 since that's the best that any real-world system supports now.
9951 But they are picosecond-resolution at the Lisp level, as that's
9952 easy, and leaves room for future OS improvements.
9954 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9957 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9958 Don't get current time unless it's needed.
9960 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9961 now provides it if it's absent.
9962 (start_atimer): Port to higher-res time stamps.
9963 Check for time stamp overflow. Don't get current time more
9964 often than is needed.
9966 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9967 Include systime.h, not time.h.
9968 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9970 * dired.c: Include stat-time.h.
9971 (Ffile-attributes): File times now have higher resolution.
9973 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9974 (struct image): Timestamp now has higher resolution.
9976 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9977 has at least microseconds now. All uses removed.
9978 (update_frame, update_single_window, update_window, update_frame_1)
9979 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9980 (duration_to_sec_usec): Remove; no longer needed.
9982 * editfns.c (time_overflow): Now extern.
9983 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9984 (float-time, Fformat_time_string, Fcurrent_time_string)
9985 (Fcurrent_time_zone): Accept and generate higher-resolution
9987 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9988 (decode_time_components, lisp_seconds_argument): New functions.
9989 (make_time): Now static.
9990 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9991 Report an error if the time is invalid, rather than having the caller
9994 * fileio.c: Include <stat-time.h>
9995 (Fcopy_file): Copy higher-resolution time stamps.
9996 Prefer to set the time stamp via a file descriptor if that works.

10010 Check for time stamp overflow.
10011 (read_char, kbd_buffer_get_event, timer_start_idle)
10012 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10013 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10014 Port to higher-resolution time stamps. Do not assume time_t is signed.
10015 (decode_timer): New function. Timers are now vectors of length 9,
10016 not 8, to accommodate the picosecond component.
10017 (timer_check_2): Use it.
10019 * nsterm.m (select_timeout, timeval_subtract): Remove.
10020 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10021 as they're a bit more accurate and handle overflow better.
10022 (ns_select): Change prototype to be compatible with pselect.
10023 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10024 * nsterm.h (ns_select): Adjust prototype.
10026 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes

10041 (wait_reading_process_output):
10042 Port to ns-resolution time stamps.
10043 (Faccept_process_output, wait_reading_process_output):
10044 Check for time stamp overflow. Do not assume time_t is signed.
10045 (select_wrapper): Remove; we now use pselect.
10046 (Fprocess_attributes): Now generates ns-resolution time stamps.
10048 * sysdep.c: Include utimens.h. Don't include utime.h
10049 or worry about struct utimbuf; gnulib does that for us now.
10050 (gettimeofday): Remove; gnulib provides a substitute.
10051 (make_timeval): New function.
10052 (set_file_times): Now sets ns-resolution time stamps.
10053 New arg FD; all uses changed.

10056 Now returns ns-resolution time stamp. All uses changed.
10057 Check for time stamp overflow.
10059 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10060 provides a substitute now.
10062 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10063 since it guarantees struct timespec.
10064 (EMACS_TIME): Now struct timespec, so that we can support
10065 ns-resolution time stamps.
10066 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10067 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10068 (EMACS_USECS): Remove.
10069 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10070 so multiply the arg by 1000 before storing it.
10071 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10073 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10080 (make_timeval, make_lisp_time, decode_time_components): New decls.
10081 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10082 that it mishandled time_t overflow. You can't compare by subtracting!
10083 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10084 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10086 * term.c: Include <sys/time.h>.

10091 in the undo buffer.
10092 (Fprimitive_undo): Use them when restoring time stamps.
10094 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10095 (w32_get_internal_run_time):
10096 Port to higher-resolution Emacs time stamps.
10097 (ltime): Now accepts single 64-bit integer, as that's more convenient
10100 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10102 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10103 for compatibility with pselect. Support ns-resolution time stamps.
10105 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10107 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10108 Check for time stamp overflow, and support ns-resolution time stamps.
10110 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10111 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10112 (timeval_subtract): Remove; no longer needed.
10113 (XTflash, XTring_bell, x_wait_for_event):
10114 Port to ns-resolution time stamps. Don't assume time_t is signed.

10120 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10122 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10123 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10124 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10125 staticidx goes up to 1597 out of 1600 = 0x640.)
10127 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10129 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10130 Otherwise, the umask might be mistakenly 0 while handling input signals.
10132 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10134 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10140 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10141 access to `contents' member of Lisp_Vector objects with AREF and ASET
10144 2012-06-19 Chong Yidong <cyd@gnu.org>
10146 * frame.c (delete_frame): When selecting a frame on a different
10147 text terminal, do not alter the terminal's top-frame.

10150 frame's selected window and its terminal's top-frame.
10151 (unwind_format_mode_line): Restore them.
10152 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10154 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

10163 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10164 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10165 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10166 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10173 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10175 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10176 gets killed during executing of this function (Bug#11665).
10177 Try to always return Qt when the buffer has been actually killed.
10178 (Vkill_buffer_query_functions): In doc-string say that functions
10179 run by this hook should not change the current buffer.
10181 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10183 Fix recently-introduced process.c problems found by static checking.

10203 * lisp.h (eassert): Assume C89 or later.
10204 This removes the need for CHECK.
10205 (CHECK): Remove. Its comments about always evaluating its
10206 argument were confusing, as 'eassert' typically does not evaluate
10209 * coding.c (produce_chars): Use ptrdiff_t, not int.
10211 * xterm.c (x_draw_underwave): Check for integer overflow.
10212 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10399 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10400 Use an inline function on all platforms when using the union type,
10401 since this is simpler and 'static inline' can be used portably

10543 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10545 * doprnt.c (doprnt): Truncate multibyte char correctly.
10546 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10547 would mishandle a string argument "Xc" if X was a multibyte
10548 character of length 2: it would truncate after X's first byte
10549 rather than including all of X.
10551 2012-06-06 Chong Yidong <cyd@gnu.org>
10553 * buffer.c (word_wrap): Doc fix.

10600 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10602 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10603 Convert pctcpu and pctmem to Lisp float properly.
10604 Let the compiler fold better, as 100.0/0x8000 is exact.
10606 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10608 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10618 bitfields where appropriate, remove unused fields.
10619 * window.h (struct window): Remove unused 'last_mark_x' and
10620 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10621 change its type from Lisp_Object to bitfield.
10622 Change type of 'force_start', 'optional_new_start',
10623 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10624 fields from Lisp_Object to bitfield. Adjust users accordingly.
10626 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10628 Pacify gcc -Wdouble-precision when using Xaw.
10629 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10630 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10631 Use 'float' consistently, rather than 'float' in most places
10632 and 'double' in a couple of places.
10634 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10636 * xdisp.c (handle_stop): Detect whether we have overlay strings
10637 loaded by testing it->current.overlay_string_index to be
10638 non-negative, instead of checking whether n_overlay_strings is
10639 positive. (Bug#11587)

10649 * search.c (search_buffer): Remove calls to
10650 r_alloc_inhibit_buffer_relocation, as it is now called by
10651 maybe_unify_char, which was the cause of relocation of buffer text
10654 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10656 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10657 for the duration of call to load_charset, to avoid problems with
10658 callers of maybe_unify_char that access buffer text through C
10661 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10662 decrement the inhibition flag, instead of just setting or
10665 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10667 Remove obsolete '#define static' cruft.
10668 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10669 This #undef was "temporary" in 2000; it is no longer needed
10670 now that '#define static' has gone away.
10671 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10672 (gray_bitmap_bits): Remove; no longer needed.
10673 All uses replaced with definiens.

10681 Define only on platforms that need it.
10682 * emacs.c: Include <sys/gmon.h> when profiling.

10684 (__executable_start): Remove decl, since lisp.h does it now.
10685 (safe_bcopy): Remove decl; no longer has that name.
10686 (main): Coalesce #if into single bit of code, for simplicity.
10687 Cast pointers to uintptr_t, since standard libraries want integers
10689 * lisp.h (__executable_start): New decl.
10691 2012-05-31 Glenn Morris <rgm@gnu.org>
10693 * image.c (Fimagemagick_types): Doc fix.

10716 Do not create empty overlays with the evaporate property (Bug#9642).
10717 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10718 Bug#9642, but explicitly check that the buffer the overlay would
10719 be moved to is live and rearrange lines to make sure that errors
10720 will not put the overlay in an inconsistent state.
10721 (Fdelete_overlay): Cosmetics.
10723 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10725 * w32term.c (my_bring_window_to_top): New function.
10726 (x_raise_frame): Use handle returned by DeferWindowPos, which
10727 could be different from the original one.

10760 Only r_alloc_inhibit_buffer_relocation needed to be added;
10761 the others were already declared.
10763 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10764 before checking whether it's out of range. Put the check inside
10766 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10768 2012-05-27 Ken Brown <kbrown@cornell.edu>

10784 * search.c (search_buffer): Use it to inhibit relocation of buffer
10785 text while re_search_2 is doing its job, because re_search_2 is
10786 passed C pointers to buffer text. (Bug#11519)
10788 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10789 Update value to 24.
10791 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10792 state after an additional call to move_it_in_display_line_to, keep
10793 the values of it->max_ascent and it->max_descent found for the
10795 (pos_visible_p): Revert the comparison against bottom_y to what it
10796 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10799 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10801 Fix coding-related core dumps with gcc -ftrapv.
10802 The code was computing A - B, where A and B are pointers, and B is
10803 random garbage. This can lead to core dumps on platforms that
10804 have special pointer registers, and it also leads to core dumps on
10805 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10806 A - B only when B is initialized properly.
10807 * coding.c (coding_set_source, coding_set_destination): Return void.
10808 (coding_change_source, coding_change_destinations): New functions,

10825 (initialize_w32_display): Initialize mouse-highlight data.
10827 * w32inevt.c: Include termchar.h and window.h.
10828 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10829 moves, call note_mouse_highlight. If help_echo changed, call
10830 gen_help_event to produce help-echo message in the echo area.
10831 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10834 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10836 * lread.c (read1): Simplify slightly to avoid an overflow warning
10837 with GCC 4.7.0 on x86-64.
10839 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10841 * bidi.c (bidi_mirror_char): Revert last change: an int is

10858 Use int, not EMACS_INT, where int is wide enough.
10859 (inhibit_garbage_collection, Fgarbage_collect):

10880 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10881 (validate_region): Omit unnecessary test for b <= e,
10882 since that's guaranteed by the previous test.
10883 (adjust_overlays_for_delete): Avoid pos + length overflow.
10884 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10885 (report_overlay_modification):
10886 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10887 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10888 Omit pointer cast, which isn't needed anyway, and doesn't work
10889 after the EMACS_INT -> ptrdiff_t change.
10890 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10891 * buffer.h: Adjust decls to match defn changes elsewhere.

10895 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10896 not int, to avoid needless 32-bit limit on 64-bit hosts.
10897 (exec_byte_code): Use tighter memory-full test, one that checks
10898 for alloca overflow. Don't compute the address of the object just
10899 before an array, as that's not portable. Use EMACS_INT, not
10900 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10901 * callint.c (Fcall_interactively):
10902 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10903 * callproc.c (call_process_kill, Fcall_process):
10904 Don't assume pid_t fits into an Emacs fixnum.

10913 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10914 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10915 (casify_object): Avoid integer overflow when overallocating buffer.
10916 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10917 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10918 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10919 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10920 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

10923 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10924 For CCL_MapSingle, check that content and value are in int range.
10925 (ccl_driver, Fregister_code_conversion_map):
10926 Check that Vcode_version_map_vector is a vector.
10927 (resolve_symbol_ccl_program): Check that vector header is in range.
10928 Always copy the vector, so that we can check its contents reliably
10929 now rather than having to recheck each instruction as it's being
10930 executed. Check that vector words fit in 'int'.
10931 (ccl_get_compiled_code, Fregister_ccl_program)
10932 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10933 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

10935 contents are in range.
10936 (Fccl_execute_on_string): Check that status is in range.
10937 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10938 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10939 Accept and return EMACS_INT, not int, because callers can pass values
10940 out of 'int' range.

10946 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10947 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10948 avoid mishandling large integers.

10957 Remove now-unnecessary CHECK_NATNUMs.
10958 (Fdefine_charset_internal): Check ranges here, more carefully.
10959 Don't rely on undefined behavior with signed left shift overflow.
10960 Don't assume unsigned int fits into fixnum, or that fixnum fits
10961 into unsigned int. Don't require max_code to be a valid fixnum;
10962 that's not true for gb10830 4-byte on a 32-bit host. Allow
10963 invalid_code to be a cons, for the same reason. Require code_offset
10964 to be a character. Avoid int overflow if max_char is close
10966 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10967 this is intended anyway and avoids some undefined behavior.
10968 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10969 INDEX_TO_CODE_POINT, as that's what it expects.
10970 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10971 * charset.h (DECODE_CHAR): Return int, not unsigned;
10972 this is what was intended anyway, and it avoids undefined behavior.
10973 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10974 integer-overflow issues.
10975 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10976 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10977 where the argument is EMACS_INT, and this behavior is not intended.
10978 * chartab.c (Fmake_char_table, Fset_char_table_range)
10979 (uniprop_get_decoder, uniprop_get_encoder):
10980 Don't assume fixnum fits in int.
10981 * cmds.c (move_point): New function, that does the gist of
10982 Fforward_char and Fbackward_char, but does so while checking
10983 for integer overflow more accurately.
10984 (Fforward_char, Fbackward_char): Use it.
10985 (Fforward_line, Fend_of_line, internal_self_insert)
10986 (internal_self_insert):
10987 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11650 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11652 * lread.c: Remove `read_pure' which makes no difference.
11653 (read_pure): Remove var.
11654 (unreadpure): Remove function.
11655 (readevalloop): Don't call read_list with -1 flag.
11656 (read1, read_vector): Don't test read_pure any more.
11657 (read_list): Simplify.

11668 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11670 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11673 This directory predates autoconf and is no longer needed nowadays.
11674 Move its few remaining bits of functionality to where they're needed.
11675 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

11685 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11686 (BITS_PER_EMACS_INT): New constants, replacing
11687 what used to be in config.h, but not useful in #if.
11688 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11689 define them any more.
11690 (VAL_MAX): New macro.
11692 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11693 BITS_PER_EMACS_INT, in #if.
11694 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11695 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11696 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11697 * s/ms-w32.h (DATA_START):
11698 Move here from removed file m/intel386.h.
11699 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11700 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11702 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11704 Assume C89 or later.
11705 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11706 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11708 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

11725 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11727 2012-05-19 Ken Brown <kbrown@cornell.edu>
11729 * xfns.c (x_in_use): Remove `static' qualifier.
11730 * xterm.h (x_in_use): Declare.
11731 * xgselect.c: Include xterm.h.
11732 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11733 and `display_arg' (bug#9754).
11735 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11737 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11739 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11740 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11742 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11744 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11746 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11747 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11749 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11750 reference to image_cache->refcount.
11751 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11753 2012-05-17 Juri Linkov <juri@jurta.org>
11755 * search.c (Fword_search_regexp, Fword_search_backward)
11756 (Fword_search_forward, Fword_search_backward_lax)
11757 (Fword_search_forward_lax): Move functions to isearch.el
11758 (bug#10145, bug#11381).
11760 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11762 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11764 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11766 * lread.c (init_obarray): Declare Qt and Qnil as special.
11768 2012-05-14 Glenn Morris <rgm@gnu.org>
11770 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11771 Put "libexec" before "bin", for the sake of init_callproc_1.
11773 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11775 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11777 * unexaix.c: Port to more-recent AIX compilers.
11778 (report_error, report_error_1, make_hdr, copy_sym)
11779 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11780 Make arguments const char *, not char *, to avoid violations of C
11781 standard and to fix some AIX warnings reported by Gilles Pion.
11783 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11785 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11786 already have overlays loaded.
11787 (handle_single_display_spec): Before returning without displaying
11788 fringe bitmap, synchronize the bidi iterator with the main display
11789 iterator, by calling iterate_out_of_display_property.
11790 (iterate_out_of_display_property): Detect buffer iteration by
11791 testing that it->string is a Lisp string.
11792 (get_next_display_element): When the current object is exhausted,
11793 and there's something on it->stack, call set_iterator_to_next to
11794 proceed with what's on the stack, instead of returning zero.
11795 (set_iterator_to_next): If called at the end of a Lisp string,
11796 proceed to consider_string_end without incrementing string
11797 position. Don't increment display vector index past the end of
11798 the display vector. (Bug#11417)
11799 (pos_visible_p): Don't report a position visible when move_it_to
11800 stopped at the last line of window, which happens to be scanned
11801 backwards by the bidi iteration. (Bug#11464)
11803 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11805 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11806 and right-margin display specs even if the spec is invalid or we
11807 are on a TTY, and thus unable to display on the fringes.
11808 That's because the text with the property will not be displayed anyway,
11809 so we need to signal to the caller that this is a "replacing"
11810 display spec. This fixes display when the spec is invalid or we
11813 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11815 * unexaix.c (make_hdr): Fix typo in prototype.
11816 This bug broke the build on AIX. Problem reported by Gilles Pion.
11818 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11820 * keyboard.c (kbd_buffer_get_event): Read special events also in
11821 batch mode. (Bug#11415)
11823 2012-05-12 Glenn Morris <rgm@gnu.org>
11825 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11827 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11829 * lisp.mk (lisp): Add newcomment.elc.
11831 2012-05-12 Glenn Morris <rgm@gnu.org>
11833 * Makefile.in (MKDIR_P): New, set by configure.
11834 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11836 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11838 Remove unused function hourglass_started.
11839 * dispextern.h (hourglass_started):
11840 * w32fns.c (hourglass_started):
11841 * xdisp.c (hourglass_started): Remove.
11843 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11845 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11846 Update dependencies.
11848 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11850 * xgselect.c (xg_select): Put maxfds+1 into a var.
11851 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11853 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11855 2012-05-10 Dave Abrahams <dave@boostpro.com>
11857 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11858 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11860 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11862 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11863 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11864 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11865 Initialize xd_registered_buses.
11867 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11869 Untag more efficiently if USE_LSB_TAG.
11870 This is based on a proposal by YAMAMOTO Mitsuharu in
11871 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11872 For an admittedly artificial (nth 8000 longlist) benchmark on
11873 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11874 Emacs's overall text size by 1%.
11875 * lisp.h (XUNTAG): New macro.
11876 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11877 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11878 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11879 * eval.c (Fautoload):
11880 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11881 * frame.h (XFRAME): Use XUNTAG.
11883 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11884 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11885 Remove unportable assumptions about print widths of types like
11887 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11888 intptr_t when converting between pointer and integer, to avoid GCC
11889 warnings about wrong width.
11891 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11893 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11894 stack for each reader_thread, instead of defaulting to 8MB
11895 determined by the linker. This avoids failures in creating
11896 subprocesses on Windows 7, see the discussion in this thread:
11897 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11899 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11901 Fix up display of the *Minibuf-0* buffer in the mini window.
11902 * keyboard.c (read_char): Don't clear the echo area if there's no
11904 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11905 contents of *Minibuf-0*) if there's no message displayed in its stead.
11907 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11909 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11912 2012-05-06 Chong Yidong <cyd@gnu.org>
11914 * lisp.mk (lisp): Update.
11916 2012-05-05 Jim Meyering <meyering@redhat.com>
11918 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11920 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11922 * data.c (PUT_ERROR): New macro.
11923 (syms_of_data): Use it. Add new error type `user-error'.
11924 * undo.c (user_error): New function.
11925 (Fprimitive_undo): Use it.
11926 * print.c (print_error_message): Adjust print style for `user-error'.
11927 * keyboard.c (user_error): New function.
11928 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11930 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11932 Do not limit current-time-string to years 1000..9999.
11933 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11934 (Fcurrent_time_string): Support any year that is supported by the
11935 underlying localtime representation. Don't use asctime, as it
11936 has undefined behavior for years outside the range -999..9999.
11938 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11940 Fix race conditions involving setenv, gmtime, localtime, asctime.
11941 Without this fix, interrupts could mess up code that uses these
11942 nonreentrant functions, since setting TZ invalidates existing
11943 tm_zone or tzname values, and since most of these functions return
11944 pointers to static storage.
11945 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11946 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11947 Grow the critical sections to include not just invoking
11948 localtime/gmtime, but also accessing these functions' results
11949 including their tm_zone values if any, and any related TZ setting.
11950 (format_time_string): Last arg is now struct tm *, not struct tm **,
11951 so that the struct tm is saved in the critical section.
11952 All callers changed. Simplify allocation of initial buffer, partly
11953 motivated by the fact that memory allocation needs to be outside
11954 the critical section.
11956 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11958 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11959 with RESET_INTERVAL.

11970 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11972 * xdisp.c (pos_visible_p): If already at a newline from the
11973 display string before the 'while' loop, don't walk back the glyphs
11974 from it3.glyph_row. Solves assertion violation when the display
11975 string begins with a newline (egg.el). (Bug#11367)
11977 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>

11985 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11986 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11987 All were removed before 23.1.
11989 * dispnew.c: Remove HAVE_LIBNCURSES test;
11990 it is always true on relevant platforms.
11992 * Makefile.in (LD_SWITCH_X_SITE_RPATH):

12005 Do not avoid creating empty evaporating overlays (Bug#9642).
12006 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12007 That is, do not delete an evaporating overlay if it becomes
12008 empty after its bounds are adjusted to fit within its buffer.
12009 This fix caused other problems, and I'm reverting it until we get
12010 to the bottom of them.
12012 2012-04-27 Chong Yidong <cyd@gnu.org>
12014 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12016 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12018 * xdisp.c (pos_visible_p): If the window start position is beyond
12019 ZV, start the display from buffer beginning. Prevents assertion
12020 violation in init_iterator when the minibuffer window is scrolled
12021 via the scroll bar.
12023 * window.c (window_scroll_pixel_based): Likewise.
12025 2012-04-27 Chong Yidong <cyd@gnu.org>

12032 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12034 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12036 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12037 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12039 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12041 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12042 display element, check also the underlying string or buffer
12043 character. (Bug#11341)
12045 * w32menu.c: Include w32heap.h.
12046 (add_menu_item): If the call to AppendMenuW (via
12047 unicode_append_menu) fails, disable Unicode menus only if we are
12048 running on Windows 9X/Me.
12050 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12052 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12053 (xgetint): Add missing shift for LSB tags.
12055 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12057 * keyboard.c (read_char): Don't wipe echo area for select window
12058 events: These might get delayed via `mouse-autoselect-window'

12063 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12064 manipulation of :loaded-from data.
12066 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12068 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12069 now a cons (bug#11311).
12071 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12073 Do not create empty overlays with the evaporate property (Bug#9642).
12074 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12075 if it becomes empty after its bounds are adjusted to fit within
12076 its buffer. Without this fix, in a nonempty buffer (let ((o
12077 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12078 yields an empty overlay that has the evaporate property, which is
12079 not supposed to happen.

12197 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12198 Use Emacs indenting style more consistently. Avoid some casts.

12284 (NEED_MEM_INSERT): New macro.
12285 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.

12388 Pass EMACS rather than BUILT_EMACS.
12390 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12392 * process.c (make_process):
12393 * process.h: Add integer `gnutls_handshakes_tried' member to
12396 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
12397 Add convenience `GNUTLS_LOG2i' macro.
12399 * gnutls.c (gnutls_log_function2i): Convenience log function.
12400 (emacs_gnutls_read): Use new log functions,
12401 `gnutls_handshakes_tried' process member, and
12402 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12403 attempts per process (connection).
12405 2012-04-09 Chong Yidong <cyd@gnu.org>
12407 * eval.c (Fuser_variable_p, user_variable_p_eh)
12408 (lisp_indirect_variable): Functions deleted.
12409 (Fdefvar): Caller changed.
12411 * callint.c (Finteractive, Fcall_interactively):
12412 * minibuf.c (Fread_variable): Callers changed.
12414 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12416 * xdisp.c (set_cursor_from_row): If the display string appears in
12417 the buffer at position that is closer to point than the position
12418 after the display string, display the cursor on the first glyph of
12419 the display string. Fixes cursor display when a 'display' text
12420 property immediately follows invisible text. (Bug#11094)
12422 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12424 composite.c: use 'double' consistently
12425 * composite.c (get_composition_id): Use 'double' consistently
12426 instead of converting 'float' to 'double' and vice versa; this is
12427 easier to understand and avoids a GCC warning.
12429 2012-04-09 Glenn Morris <rgm@gnu.org>
12431 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12432 preparation for dumping it with emacs. (Bug#4789)
12433 (leimdir): New variable.
12434 ($(leimdir)/leim-list.el): New rule.
12435 (emacs$(EXEEXT)): Depend on leim-list.el.
12437 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)

12449 Remove unused local variable.
12451 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12453 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12454 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12455 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12456 objects, as mark_maybe_pointer will catch them otherwise.
12457 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12458 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
12460 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12462 Fix typo that broke non-Windows builds.
12463 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
12465 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12467 Support building on MS-Windows with libxml2.
12469 * makefile.w32-in (OBJ2): Add xml.$(O).
12470 (GLOBAL_SOURCES): Add xml.c.
12471 ($(BLD)/xml.$(O)): New dependency list.
12473 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12474 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12475 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12476 [!WINDOWSNT]: New macros.
12477 (init_libxml2_functions, libxml2_loaded_p): New functions.
12478 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12479 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12480 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12481 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12483 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12484 Call init_libxml2_functions before calling libxml2 functions.
12485 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12487 * emacs.c: Don't include libxml/parser.h.
12488 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12489 xmlCleanupParser directly.
12491 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12493 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12495 * indent.c (Fvertical_motion): If there is a display string at
12496 point, use it.vpos to compute how many lines to backtrack after
12497 move_it_to point. (Bug#11133)
12499 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12501 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12502 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12503 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12504 macros related to unification of CJK characters. For the details,
12505 see the discussion following the message here:
12506 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12508 2012-04-04 Chong Yidong <cyd@gnu.org>
12510 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12512 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12514 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12515 instead of alloca. (Bug#11138)
12517 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12519 * w32menu.c (is_simple_dialog): Properly check lisp types.
12522 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12524 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12525 position we get to after a call to move_it_to fails the
12526 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12527 only if we wind up in a string from display property. (Bug#11063)
12529 * window.c (Fdelete_other_windows_internal): Invalidate the row
12530 and column information about mouse highlight, so that redisplay
12531 restores it after reallocating the glyph matrices. (Bug#7464)
12533 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12534 string comes from a `display' text property, use the buffer
12535 position of that property as if we actually saw that position in
12537 (move_it_by_lines): Remove the assertion that
12538 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12539 violated when there's a before-string at the beginning of a line.
12542 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12544 * xdisp.c (append_space_for_newline): If the default face was
12545 remapped, use the remapped face for the appended newline.
12546 (extend_face_to_end_of_line): Use the remapped default face for
12547 extending the face to the end of the line.
12548 (display_line): Call extend_face_to_end_of_line when the default
12549 face was remapped. (Bug#11068)
12551 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12553 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12555 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12557 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12559 2012-03-27 Glenn Morris <rgm@gnu.org>
12561 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12564 2012-03-26 Kenichi Handa <handa@m17n.org>
12566 * dispextern.h (struct glyph): Fix previous change. Change the
12567 bit length of glyphless.ch to 25 (Bug#11082).
12569 2012-03-26 Chong Yidong <cyd@gnu.org>
12571 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12572 (command_loop_1): Use it; inhibit selection update for
12573 handle-select-window too (Bug#8996).
12575 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12577 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12579 2012-03-25 Kenichi Handa <handa@m17n.org>
12581 * dispextern.h (struct glyph): Change the bit length of
12582 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12584 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12586 * s/ms-w32.h (tzname): Include time.h before redirecting to
12587 _tzname. Fixes the MSVC build. (Bug#9960)
12589 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12591 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12594 * xterm.c (XTread_socket): Only modify handling_signal if
12595 !SYNC_INPUT. (Bug#11080)
12597 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12599 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12600 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12601 when fetching a multibyte character consumes more bytes than
12602 CHAR_BYTES returns, due to unification of CJK characters in
12603 string_char. (Bug#11073)
12605 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12607 * process.c (wait_reading_process_output): Handle pty disconnect
12608 by refraining from sending oneself a SIGCHLD (bug#10933).
12610 2012-03-22 Chong Yidong <cyd@gnu.org>

12615 Mark string as coming from a prefix property.
12616 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12617 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12619 2012-03-21 Chong Yidong <cyd@gnu.org>
12621 * xfaces.c (Vface_remapping_alist): Doc fix.
12623 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12625 * w32proc.c (Fw32_set_console_codepage)
12626 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12629 2012-03-20 Chong Yidong <cyd@gnu.org>
12631 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12632 to reflect default non-nil value of redisplay-dont-pause.
12634 2012-03-19 Kenichi Handa <handa@m17n.org>
12636 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12637 it fit in a valid range (Bug#11003).
12639 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12641 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12642 that is not from display property, accept the row as a "cursor
12643 row" if one of the string's character has a non-nil `cursor'
12644 property. Fixes cursor positioning when there are newlines in
12645 overlay strings, e.g. in icomplete.el. (Bug#11035)
12647 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12649 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12651 2012-03-12 Chong Yidong <cyd@gnu.org>
12653 * eval.c (inhibit_lisp_code): Rename from
12654 inhibit_window_configuration_change_hook; move from window.c.
12656 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12657 * window.c (run_window_configuration_change_hook)
12658 (syms_of_window): Callers changed.
12660 2012-03-11 Chong Yidong <cyd@gnu.org>

12664 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12666 2012-03-10 Chong Yidong <cyd@gnu.org>
12668 * frame.c (other_visible_frames): Don't assume the selected frame
12669 is visible (Bug#10955).
12671 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12673 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

12677 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12678 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12681 2012-03-03 Glenn Morris <rgm@gnu.org>
12683 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12685 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12687 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12688 position past the first glyph_row that ends at ZV. (Bug#10902)
12689 (redisplay_window, next_element_from_string): Fix typos in
12691 (redisplay_window): Pass to move_it_vertically the margin in
12692 pixels, not in screen lines.
12694 2012-03-02 Glenn Morris <rgm@gnu.org>
12696 * buffer.c (buffer-list-update-hook): Doc fix.
12698 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12700 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12701 push_it before setting up the iterator for the first overlay
12702 string, even if we have an empty string loaded.
12703 (next_overlay_string): If there's an empty string on the iterator
12704 stack, pop the stack. (Bug#10903)
12706 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12708 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12709 Suggested by Stefan Monnier in
12710 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12711 * alloc.c (widen_to_Lisp_Object): New static function.
12712 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12713 and widening them to Lisp_Objects. This would work even if
12714 USE_LSB_TAG is defined and wide integers are used, which might
12715 happen in a future version of Emacs.
12717 2012-02-25 Chong Yidong <cyd@gnu.org>
12719 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12722 * xselect.c (Fx_selection_exists_p): Doc fix.
12723 (x_clipboard_manager_save_all): Print an informative message
12724 before saving to clipboard manager.
12726 2012-02-24 Chong Yidong <cyd@gnu.org>
12728 * keyboard.c (process_special_events): Handle all X selection
12729 requests in kbd_buffer, not just the next one (Bug#8869).
12731 2012-02-23 Chong Yidong <cyd@gnu.org>
12733 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12734 call when setting menu-bar-lines and tool-bar-lines parameters.
12735 (unwind_create_frame_1): New helper function.
12737 * window.c (inhibit_window_configuration_change_hook): New var.
12738 (run_window_configuration_change_hook): Obey it.

12756 when computing $valmask.
12758 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12759 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12760 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12761 It's useless in that case, and it can cause problems on hosts
12762 that allocate halves of EMACS_INT values separately.
12763 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12764 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12765 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12766 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12767 it avoids undefined behavior on hosts where shifting right by more
12768 than the word width has undefined behavior.
12770 2012-02-19 Chong Yidong <cyd@gnu.org>
12772 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12773 (Funhandled_file_name_directory, Ffile_name_as_directory)
12774 (Fdirectory_file_name, Fexpand_file_name)
12775 (Fsubstitute_in_file_name): Protect against invalid file handler
12776 return values (Bug#10845).
12778 2012-02-18 Eli Zaretskii <eliz@gnu.org>
12780 * .gdbinit (pitx): Fix incorrect references to fields of the

12787 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
12789 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
12790 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12792 2012-02-15 Chong Yidong <cyd@gnu.org>
12794 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12795 marked as special. Also, starting docstrings with * is obsolete.
12797 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
12799 * gnutls.c (emacs_gnutls_write): Fix last change.

12810 2012-02-12 Chong Yidong <cyd@gnu.org>
12812 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12813 as that creates a dangerous corner case.
12815 * window.c (Fdelete_window_internal): Invalidate the mouse
12816 highlight (Bug#9904).
12818 2012-02-12 Glenn Morris <rgm@gnu.org>
12820 * xselect.c (Fx_own_selection_internal)
12821 (Fx_get_selection_internal, Fx_disown_selection_internal)
12822 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12823 * nsselect.m (Fx_own_selection_internal)
12824 (Fx_disown_selection_internal, Fx_selection_exists_p)
12825 (Fx_selection_owner_p, Fx_get_selection_internal):
12826 Sync docs and argument specs with the xselect.c versions.
12828 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12830 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
12832 2012-02-11 Eli Zaretskii <eliz@gnu.org>
12834 * w32select.c (Fx_selection_exists_p): Sync doc string and
12835 argument list with xselect.c. (Bug#10783)
12837 * w16select.c (Fx_selection_exists_p): Sync doc string and
12838 argument list with xselect.c. (Bug#10783)

12848 2012-02-07 Chong Yidong <cyd@gnu.org>
12850 * buffer.c (Fbuffer_local_variables)
12851 (buffer_lisp_local_variables): Handle unbound vars correctly;
12852 don't let Qunbound leak into Lisp.
12854 2012-02-07 Glenn Morris <rgm@gnu.org>
12856 * image.c (Fimagemagick_types): Doc fix.
12858 * image.c (imagemagick-render-type): Change it from a lisp object
12859 to an integer. Move the doc here from the lisp manual.
12860 Treat all values not equal to 0 the same.
12862 2012-02-06 Chong Yidong <cyd@gnu.org>
12864 * doc.c (store_function_docstring): Avoid applying docstring of

13373 * fileio.c (Finsert_file_contents): Move after-change-function call
13374 to before the "handled:" label, since all "goto handled" appear in
13375 cases where the *-change-functions have already been properly called
13378 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
13380 * keyboard.c (interrupt_signal): Don't call kill-emacs when

13385 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13386 verifies glyph row's hash code--we have just reallocated the
13387 glyphs, so their contents can be complete garbage. (Bug#10164)

13433 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13434 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13435 this macro definition.
13437 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

13462 * xdisp.c (redisplay_window): If cursor row is not fully visible
13463 after recentering, and scroll-conservatively is set to a large
13464 number, scroll window by a few more lines to make the cursor fully
13465 visible and out of scroll-margin. (Bug#10105)
13466 (start_display): Don't move to the next line if the display should
13467 start at a newline that is part of a display vector or an overlay

13547 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13548 Otherwise, valgrind does not work on some platforms.
13549 Problem reported by Andreas Schwab in
13550 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13551 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13552 is set, removing the need for VIRT_ADDRESS_VARIES.
13553 (PURE_P): Use a more-efficient implementation that needs just one
13554 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13555 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13556 to 4 (xorl, subq, cmpq, setbe).
13557 * alloc.c (pure): Always extern now, since that's the
13558 VIRT_ADDR_VARIES behavior.
13559 (PURE_POINTER_P): Use a single comparison, not two, for
13560 consistency with the new puresize.h.
13561 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13562 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13568 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13569 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13570 behave as if the cursor position were at the window margin.
13572 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13573 and the cursor position is out of bounds, behave as if the cursor
13574 position were at the window margin. (Bug#10075)
13576 2011-11-18 Chong Yidong <cyd@gnu.org>
13578 * window.c (Fwindow_combination_limit): Make first argument

13597 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13599 * xdisp.c (row_hash): New function, body extracted from
13600 compute_line_metrics.
13601 (compute_line_metrics): Call row_hash, instead of computing the
13604 * dispnew.c (verify_row_hash): Call row_hash for computing the
13605 hash code of a row, instead of duplicating code from xdisp.c.
13607 * dispextern.h (row_hash): Add prototype.
13609 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13611 * frame.c (delete_frame): Don't delete the terminal when the last

13637 (Fsplit_window_internal, saved_window)
13638 (Fset_window_configuration, save_window_save): Rename all
13639 occurrences of window_nest to window_combination_limit.

13645 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13647 * xdisp.c (display_line): Move the call to
13648 highlight_trailing_whitespace before the call to
13649 compute_line_metrics, since the latter needs to see the final
13650 faces of all the glyphs to compute ROW's hash value.
13651 Fixes assertion violations in row_equal_p. (Bug#10035)
13653 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13655 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

13660 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13661 with user-defined heap size. Bump the default size of the temacs
13662 heap to 27MB, to avoid memory warning when running temacs.
13663 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13665 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13666 current_matrix and desired_matrix. (Bug#9990)
13667 (verify_row_hash) [XASSERTS]: New function.
13668 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

13712 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13714 Avoid some portability problems by eschewing 'extern inline' functions.
13715 The trivial performance wins aren't worth the portability hassles; see
13716 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13718 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13719 (window_box_width, window_box_left, window_box_left_offset)
13720 (window_box_right, window_box_right_offset): Undo previous change,
13721 by removing the "extern"s.
13722 * intervals.c (adjust_intervals_for_insertion)
13723 (adjust_intervals_for_deletion): Undo previous change,
13724 making these static again.

13792 (window_box_width, window_box_left, window_box_left_offset)
13793 (window_box_right, window_box_right_offset): Declare extern.
13794 Otherwise, these inline functions do not conform to C99 and
13795 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13796 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13797 * intervals.c (adjust_intervals_for_insertion)

13799 extern inline functions 'offset_intervals' couldn't refer to it.
13800 (static_offset_intervals): Remove.
13801 (offset_intervals): Rewrite using the old contents of
13802 static_offset_intervals. The old version didn't conform to C99

14108 (bidi_resolve_weak): Don't enter the expensive loop if the current
14109 position is before next_en_pos. Record the bidi type of the first
14110 non-ET, non-BN character we find, in addition to its position.
14111 (bidi_level_of_next_char): Invalidate next_en_type when
14112 next_en_pos is over-stepped.
14114 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14116 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14117 * editfns.c: Rewrite current-time-zone so that it invokes
14118 the equivalent of (format-time-string "%Z") to get the time zone name.
14119 This fixes a bug when the time zone name contains characters that
14120 need converting from the system time locale to Emacs internal format.
14121 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14122 that patch fixed format-time-string to do the conversion, but
14123 I forgot to fix current-time-zone.
14124 (format_time_string): New function, containing most of
14125 what Fformat_time_string used to contain.
14126 (Fformat_time_string): Rewrite in terms of format_time_string.
14127 This doesn't change this function's behavior.
14128 (current-time-zone): Rewrite to use format_time_string.
14129 This fixes the bug reported by Michael Schierl in
14130 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14131 Jason Rumney's 2007-06-07 change worked around this bug, but
14133 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14135 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14137 * xdisp.c (start_display): If the character at POS is displayed
14138 via a display vector, reset IT->current.dpvec_index to zero.
14139 (try_window_reusing_current_matrix): If a line ends in a display
14140 vector or the next line starts in a display vector, continue
14141 redrawing the window even though the character position of
14142 start_row was reached.
14145 2011-10-18 Chong Yidong <cyd@gnu.org>
14147 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14148 with nobreak-char-display too.
14150 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14152 Fix part 3 of bug#9771.
14153 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14154 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14155 non-neutral characters if the current character is a paragraph
14156 separator (a.k.a. Newline). This avoids running the same
14157 expensive loop twice, once when we consume the preceding newline
14158 and the other time when the line actually needs to be displayed.
14159 Avoid the loop when we see neutrals on the base embedding level
14160 following a character whose directionality is the same as the
14161 paragraph's. This avoids running the expensive loop when a line
14162 ends in a long sequence of neutrals, like control characters.
14163 Add assertion against STRONG_AL type. Slightly rearrange code
14164 that determines the type of a neutral given the first non-neutral
14166 (bidi_level_of_next_char): Set next_en_pos to zero when
14167 invalidating its info.
14169 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14171 * xdisp.c (push_display_prop): Determine whether to record string
14172 or buffer position by IT->string, not by IT->method. Allow
14173 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14174 (move_it_vertically_backward): Don't look for character position
14175 immediately after the newline when in a continuation line.
14178 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14180 * window.c (coordinates_in_window): Rewrite and delabelize
14181 vertical border check. (Bug#5357) (Bug#9618)

14190 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14191 avoid crash when xmalloc overrun checking is enabled.
14193 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14195 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14196 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14197 cursor motion with <left> and <right> arrow keys.
14199 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14200 some callers set that themselves.
14202 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14204 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14205 display string and the previous row comes from the same string and
14206 is empty. (Bug#9739) (Bug#9738)
14208 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14210 * doc.c (get_doc_string): Encode file name (bug#9735).
14212 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14214 * bidi.c (bidi_level_of_next_char):
14215 * xdisp.c (get_visually_first_element): Remove old incorrect
14216 comments regarding the Unicode Line Separator character.
14218 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.

14229 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14231 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14232 Some packages use them to denote characters with modifiers.
14234 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14236 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14237 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14238 matching a pp-number. Rename parameter var to var1.

14261 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14262 Don't advertise functionality which we discourage or doesn't work.
14264 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14266 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14267 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14268 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14269 this makes Emacs dump core during garbage collection on rare
14270 occasions. sizeof is obviously inferior to offsetof here, so
14271 stick with offsetof.
14272 (GC_POINTER_ALIGNMENT): New macro.
14273 (mark_memory): Omit 3rd (offset) arg; caller changed.
14274 Don't assume EMACS_INT alignment is the same as pointer alignment.
14276 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14278 * keyboard.c (read_key_sequence_remapped): New var.
14279 (read_key_sequence): Compute remapping in the right buffer.
14280 (command_loop_1): Use read_key_sequence's remapping directly.
14282 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14284 * dired.c (file_name_completion): Don't expand file name.
14285 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14286 before checking file name handler.
14288 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14289 they've been requested explicitly (bug#9591).
14291 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14293 * keymap.c (Fsingle_key_description): Use make_specified_string
14294 instead of build_string to build string from push_key_description.
14297 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14299 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14300 This fixes a Y2038 bug on 64-bit hosts.
14301 * buffer.c (reset_buffer):
14302 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14303 (Fclear_buffer_auto_save_failure):
14304 Use 0, not -1, to represent an unset failure time, since time_t
14305 might not be signed.
14307 Remove dependency on glibc malloc internals.
14308 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14309 Move back here from lisp.h, but with their new implementations.
14310 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14311 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14312 * charset.c (charset_table_init): New static var.
14313 (syms_of_charset): Use it instead of xmalloc. This removes a
14314 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14315 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14316 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14317 Move back to alloc.c.
14318 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14319 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14321 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14323 * nsterm.m (windowDidResize): Call x_set_window_size only when
14324 ns_in_resize is true. Otherwise set pixelwidth/height and
14325 call change_frame_size (Bug#9628).
14327 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14329 Port --enable-checking=all to Fedora 14 x86-64.
14330 * charset.c (syms_of_charset): Also account for glibc malloc's
14331 internal overhead when calculating the initial malloc maximum.
14333 Port --enable-checking=all to Fedora 14 x86.
14334 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14336 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14337 (overrun_check_realloc, overrun_check_free):
14338 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14339 That way, xmalloc returns a properly-aligned pointer even if
14340 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14341 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14342 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14343 into account when calculating the initial malloc maximum.
14344 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14345 Move here from alloc.c, so that charset.c can use it too.
14346 Properly align; the old code wasn't right for common 32-bit hosts
14347 when configured with --enable-checking=all.
14348 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14349 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14351 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14353 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14356 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14358 * xdisp.c (compute_display_string_end): If there's no display
14359 string at CHARPOS, return -1.
14361 * bidi.c (bidi_fetch_char): When compute_display_string_end
14362 returns a negative value, treat the character as a normal
14363 character not covered by a display string. (Bug#9624)
14365 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14367 * lread.c (Fread_from_string): Fix typo in docstring.
14369 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14371 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14372 newline, reseat the iterator instead of bidi-iterating there one
14373 character at a time. (Bug#9610)
14374 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14375 TO_CHARPOS if the bidi iterator is at base embedding level.
14377 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14379 * lread.c (readevalloop): Use correct code for NBSP.
14380 (read1): Likewise. (Bug#9608)
14382 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14384 * dbusbind.c (Fdbus_register_signal): When service is not
14385 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14387 2011-09-25 Glenn Morris <rgm@gnu.org>
14389 * buffer.c (truncate-lines): Doc fix.
14391 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14393 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14394 (Fset_window_next_buffers): Doc fix.
14396 2011-09-24 Glenn Morris <rgm@gnu.org>
14398 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14400 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14402 Fix minor problems found by static checking.
14403 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14404 * indent.c (Fvertical_motion): Fix == vs = typo.
14406 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14408 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14409 Default value is now t. Doc fix.
14411 * indent.c (Fvertical_motion): Compute and apply the overshoot
14412 logic when moving up, not only when moving down. Fix the
14413 confusing name and values of the it_overshoot_expected variable;
14414 logic changes accordingly. (Bug#9254) (Bug#9549)
14416 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14417 CHARPOS is covered by a display string which includes newlines.
14418 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14419 is covered by a display string with embedded newlines.
14421 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14423 * dbusbind.c (Fdbus_register_signal): Add match rule to
14424 Vdbus_registered_objects_table. (Bug#9581)
14425 (Fdbus_register_method, Vdbus_registered_objects_table):
14428 2011-09-24 Jim Meyering <meyering@redhat.com>
14430 do not ignore write error for any output size
14431 The previous change was incomplete.
14432 While it makes emacs --batch detect the vast majority of stdout
14433 write failures, errors were still ignored whenever the output size is
14434 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14435 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14436 && echo FAIL: ignored write error
14437 FAIL: ignored write error
14438 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14439 && echo FAIL: ignored write error
14440 FAIL: ignored write error
14441 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14443 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14445 * emacs.c (Fkill_emacs): In noninteractive mode exit
14446 non-successfully if a write error occurred on stdout. (Bug#9574)
14448 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14450 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14453 * dispextern.h (struct it): Update the comment documenting what
14456 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14458 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14459 a display string, extend search for cursor position to end of row.
14460 (find_row_edges): If the row ends in a newline from a display
14461 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14462 Handle the case of a display string with multiple newlines.
14463 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14464 non-empty line. Fixes confusing cursor motion with arrow keys at
14465 the beginning of a line that starts with whitespace.
14467 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14469 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14472 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14474 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14475 boolean (Bug#9154).
14477 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14479 * xdisp.c (display_line): Record maximum and minimum buffer
14480 positions even if no glyphs were produced (e.g., by a zero-width
14481 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14482 buffer positions that will be removed from the glyph row because
14484 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14485 column is beyond frame width: don't subtract 1 "pixel" when
14486 computing width of the stretch.
14487 (reseat_at_next_visible_line_start): Undo the change made on
14488 2011-09-17 that saved paragraph information and restored it after
14489 the call to `reseat'. (Bug#9545)
14491 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14493 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14494 and turn window cursor on if cleared (Bug#9415).
14496 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14498 * search.c (boyer_moore): Take unibyte characters from pattern
14499 literally. (Bug#9458)
14501 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14503 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14505 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14507 Fix minor problem found by static checking.
14508 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14509 initialized, to pacify gcc -Wuninitialized.
14511 * fileio.c: Report proper errno when syscall falls.
14512 (Finsert_file_contents): Save and restore errno,
14513 so that report_file_error outputs the correct diagnostic.
14514 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14516 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14518 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14520 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14522 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14523 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14525 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14527 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14528 about the current paragraph and restore it after the call to reseat.
14530 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14531 (bidi_find_paragraph_start): Search back for paragraph beginning
14532 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14533 (bidi_move_to_visually_next): Only trigger paragraph-related
14534 computations when the last character is a newline or at EOB, not
14535 just any NEUTRAL_B. (Bug#9470)
14537 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14538 truncated lines if point is covered by a display string. (Bug#9524)
14540 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14542 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14543 (cons_to_x_long): New function.
14544 (lisp_data_to_selection_data): Use it. Correct the test for
14545 short-versus-long data; it was negated. Break out of vector
14546 loop, for efficiency, when a long datum is discovered.
14548 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14550 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14552 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14554 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14555 GCC PR/17406) by declaring this function with external scope.
14557 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14559 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14560 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14562 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14564 * editfns.c (Fformat): Correctly handle text properties on "%%".
14566 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14568 * xterm.c (x_draw_composite_glyph_string_foreground):
14569 * w32term.c (x_draw_composite_glyph_string_foreground):
14570 * term.c (encode_terminal_code):
14571 * composite.c (composition_update_it, get_composition_id):
14572 * xdisp.c (get_next_display_element)
14573 (fill_composite_glyph_string): Add comments about special meaning
14574 of TAB characters in a composition.
14576 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14578 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14579 This occurs when processing a multibyte format.
14580 Problem reported by Wolfgang Jenker.
14582 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14584 * xdisp.c (try_cursor_movement): Only check for exact match if
14585 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14587 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14589 Remove unused external symbols.
14590 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14591 * xdisp.c (calc_pixel_width_or_height): Now static.
14592 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14593 * indent.c (check_display_width):
14594 * w32term.c: Fix comment to match code.
14595 * xterm.c, xterm.h (x_catching_errors): Remove.
14597 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14599 * xselect.c: Use signed conversions more consistently (Bug#9498).
14600 (selection_data_to_lisp_data): Assume incoming selection data are
14601 signed integers, not unsigned. This is to be consistent with
14602 outgoing selection data, which was modified to use signed integers
14603 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14604 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14605 expects long, not unsigned long.
14607 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14609 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14610 computation of loop end. Reported by Johan Bockgård
14613 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14615 * frame.c (Fother_visible_frames_p): Function deleted.
14617 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14619 * indent.c (compute_motion): Process display vector front to back
14620 rather than the other way around. (Bug#2496)
14622 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14624 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14626 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14628 * minibuf.c (Fread_from_minibuffer): Doc fix.
14630 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14632 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14633 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14635 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14637 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14638 value for non-existent files.
14640 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14642 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14643 set its "size" to -1. This will set the modtime_size field of
14644 the corresponding buffer to -1, which is what
14645 verify-visited-file-modtime expects for files that do not exist.
14648 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14650 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14652 * lisp.h: ... from here. push_key_description is no longer
14653 defined in keyboard.c, so its declaration should not be in
14654 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14655 logically belongs with push_key_description.
14657 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14659 * buffer.h: Include <sys/types.h> instead of <time.h>.
14660 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14661 Problem reported by Herbert J. Skuhra.
14663 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14665 * xml.c (parse_region): Make the parsing work for
14666 non-comment-starting XML files again (bug#9144).
14668 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14670 * image.c (gif_load): Fix calculation of bottom and right corner.
14673 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14675 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14676 redisplay in small windows.
14678 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14680 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14682 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14684 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14685 Operate on live windows only.
14687 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14689 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14691 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14693 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14694 only under bidi iteration.
14696 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14698 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14700 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14702 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14703 Without this fix, the command to link temacs failed due to an
14704 undefined symbol __builtin_isnan. This is because
14705 /usr/include/iso/math_c99.h #defines isnan(x) to
14706 __builtin_isnan(x), but the bundled gcc, which identifies itself
14707 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14709 * floatfns.c (isnan): #undef, and then #define to a clone of
14711 (Fisnan): Always define, since it's always available now.
14712 (syms_of_floatfns): Always define isnan at the Lisp level.
14714 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14716 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14718 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14720 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14721 The previous code assumed that file offsets (off_t values) fit in
14722 EMACS_INT variables, which is not true on typical 32-bit hosts.
14723 The code messed up by falsely reporting buffer overflow in cases
14724 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14725 when "big" contains more than 2**29 bytes, even though this
14726 inserts just one byte and does not overflow the buffer.
14727 (Finsert_file_contents): Store file offsets as off_t
14728 values, not as EMACS_INT values. Check for overflow when
14729 converting between EMACS_INT and off_t. When checking for
14730 buffer overflow or for overlap, take the offsets into account.
14731 Don't use EMACS_INT for small values where int suffices.
14732 When checking for overlap, fix a typo: ZV was used where
14733 ZV_BYTE was intended.
14734 (Fwrite_region): Don't assume off_t fits into 'long'.
14735 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14737 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14739 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14741 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14743 sprintf-related integer and memory overflow issues (Bug#9412).
14745 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14746 (esprintf, exprintf, evxprintf): New functions.
14747 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14748 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14749 (modify_event_symbol): Do not assume that the length of
14750 name_alist_or_stem is safe to alloca and fits in int.
14751 (Fexecute_extended_command): Likewise for function name and binding.
14752 (Frecursion_depth): Wrap around reliably on integer overflow.
14753 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14754 since some callers pass EMACS_INT values.
14755 (Fsingle_key_description): Don't crash if symbol name contains more
14756 than MAX_ALLOCA bytes.
14757 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14758 (get_minibuffer): Arg is now EMACS_INT, not int.
14759 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14760 (esprintf, exprintf, evxprintf): New decls.
14761 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14763 * dbusbind.c (signature_cat): New function.
14764 (xd_signature, Fdbus_register_signal):
14765 Do not overrun buffer; instead, report string overflow.
14767 * dispnew.c (add_window_display_history): Don't overrun buffer.
14768 Truncate instead; this is OK since it's just a log.
14770 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14771 even if the time zone offset is outlandishly large.
14772 Don't mishandle offset == INT_MIN.
14774 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14775 when creating daemon; the previous buffer-overflow check was incorrect.
14777 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14778 which has the guts of the old verror function.
14780 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14781 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14783 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14784 (font_unparse_xlfd): Don't blindly alloca long strings.
14785 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14786 fits in int, when using sprintf. Use single snprintf to count
14787 length of string rather than counting it via multiple sprintfs;
14788 that's simpler and more reliable.
14789 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14790 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14791 sprintf, in case result does not fit in int.
14793 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14794 (fontset_from_font): Print it.
14796 * frame.c (tty_frame_count): Now printmax_t, not int.
14797 (make_terminal_frame, set_term_frame_name): Print it.
14798 (x_report_frame_params): In X, window IDs are unsigned long,
14799 not signed long, so print them as unsigned.
14800 (validate_x_resource_name): Check for implausibly long names,
14801 and don't assume name length fits in 'int'.
14802 (x_get_resource_string): Don't blindly alloca invocation name;
14803 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14806 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14807 (xg_check_special_colors, xg_set_geometry):
14808 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14810 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14811 Use esprintf, not sprintf, in case result does not fit in int.
14813 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14814 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14815 it as a large positive number.
14816 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14817 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14819 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14820 in case result does not fit in int.
14822 * print.c (float_to_string): Detect width overflow more reliably.
14823 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14824 buffer overrun. Don't assume list length fits in 'int'. Treat
14825 print length of 0 as 0, not as infinity; to be consistent with other
14826 uses of print length in this function. Don't overflow print length
14827 index. Don't assume hash table size fits in 'long', or that
14828 vectorlike size fits in 'unsigned long'.
14830 * process.c (make_process): Use printmax_t, not int, to format
14831 process-name gensyms.
14833 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14835 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14836 to avoid potential buffer overrun.
14838 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14839 if X resource line is longer than 512 bytes.
14841 * xfns.c (x_window): Make sprintf buffer a bit bigger
14842 to avoid potential buffer overrun.
14844 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14846 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14848 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14850 Integer overflow fixes for scrolling, etc.
14851 Without these, Emacs silently mishandles large integers sometimes.
14852 For example, "C-u 4294967297 M-x recenter" was treated as if
14853 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14855 * xdisp.c (try_window_id): Check Emacs fixnum range before
14856 converting to 'int'.
14858 * window.c (window_scroll_line_based, Frecenter):
14859 Check that an Emacs fixnum is in range before assigning it to 'int'.
14860 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14861 values converted from Emacs fixnums.
14862 (Frecenter): Don't wrap around a line count if it is out of 'int'
14863 range; instead, treat it as an extreme value.
14864 (Fset_window_configuration, compare_window_configurations):
14865 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14867 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14868 that can exceed INT_MAX. Check that EMACS_INT value is in range
14869 before assigning it to the (possibly-narrower) index.
14870 (match_limit): Don't assume that a fixnum can fit in 'int'.
14872 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14875 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14876 (Fvertical_motion): Don't wrap around LINES values that don't fit
14877 in 'int'. Instead, treat them as extreme values. This is good
14878 enough for windows, which can't have more than INT_MAX lines anyway.
14880 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14882 * Require libxml/parser.h to avoid compilation warning.
14884 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14886 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14887 since this reportedly can destroy thread storage.
14889 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14891 * syntax.c (find_defun_start): Update all cache variables if
14892 exiting early (Bug#9401).
14894 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14896 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14898 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14899 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14900 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14902 * term.c (tty_append_glyph): New function.
14903 (produce_stretch_glyph): Static function and its prototype deleted.
14905 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14908 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14910 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14911 when checking :margin (Bug#9390).
14912 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14913 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14914 so that the name doesn't mislead. All uses changed.
14916 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14918 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14921 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14923 * xdisp.c (move_it_to): Don't bail out early when reaching
14924 position beyond to_charpos, if we are scanning backwards.
14925 (move_it_vertically_backward): When DY == 0, make sure we get to
14926 the first character in the line after the newline.
14928 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14930 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14931 (ccl_driver): Do not generate an out-of-range pointer.
14932 (Fccl_execute_on_string): Remove unnecessary check for
14933 integer overflow, noted by Stefan Monnier in
14934 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14935 Remove a FIXME that didn't need fixing.
14936 Simplify the newly-introduced buffer reallocation code.
14938 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14940 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14942 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14944 Integer and memory overflow issues (Bug#9196).
14946 * doc.c (get_doc_string): Rework so that
14947 get_doc_string_buffer_size is the actual buffer size, rather than
14948 being 1 less than the actual buffer size; this makes xpalloc more
14951 * image.c (x_allocate_bitmap_record, cache_image):
14952 * xselect.c (Fx_register_dnd_atom):
14953 Simplify previous changes by using xpalloc.
14955 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14956 since either will do and ptrdiff_t is convenient with xpalloc.
14958 * charset.c (charset_table_size)
14959 (struct charset_sort_data.priority): Now ptrdiff_t.
14960 (charset_compare): Don't overflow if priorities differ greatly.
14961 (Fsort_charsets): Don't assume list length fits in int.
14962 Check for size-calculation overflow when allocating sort data.
14963 (syms_of_charset): Allocate an initial charset table that is
14964 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14966 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14968 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14969 The actual value is always <= INT_MAX, and leaving it unsigned made
14970 overflow checking harder.
14972 * dispextern.h (struct glyph_matrix.rows_allocated)
14973 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14974 with xpalloc. The values are still always <= INT_MAX.
14976 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14978 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14979 (SAFE_NALLOCA): New macro.
14981 * region-cache.c (struct boundary.pos, find_cache_boundary)
14982 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14983 (set_cache_region, invalidate_region_cache)
14984 (revalidate_region_cache, know_region_cache, region_cache_forward)
14985 (region_cache_backward, pp_cache):
14986 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14987 so that ptrdiff_t * can be passed to xpalloc.
14988 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14989 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14990 (pp_cache): Don't assume cache_len fits in int.
14991 * region-cache.h: Adjust extern decls to match.
14993 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14994 EMACS_INT, since either will do, for xpalloc.
14996 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14997 (xnmalloc, xnrealloc, xpalloc): New functions.
14999 * bidi.c (bidi_shelve_header_size): New constant.
15000 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15001 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15003 * bidi.c (bidi_cache_shrink):
15004 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15006 Don't update size of array until after memory allocation succeeds,
15007 because xmalloc/xrealloc may not return.
15008 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15009 now that we have proper integer overflow checking.
15010 (record_overlay_string, overlay_strings): Catch overflows when
15011 calculating size of overlay_str_buf.
15013 * callproc.c (Fcall_process): Check for size overflow when
15014 calculating size of args2.
15015 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15016 Normally we prefer signed values, but sticking with ptrdiff_t would
15017 require adding more-complicated checks.
15019 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15020 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15021 Redo buffer-overflow calculations to avoid integer overflow.
15022 Add a FIXME comment where memory seems to be over-allocated.
15024 * character.c (Fstring): Check for size-calculation overflow.
15026 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15027 unnecessary integer overflow. Check for size overflow.
15028 (encode_coding_object): Don't update size until xmalloc succeeds.
15030 * composite.c (get_composition_id): Check for overflow in glyph
15031 length calculations.
15033 Integer and memory overflow fixes for display code.
15034 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15035 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15036 (scrolling_window): Check for overflow in size calculations.
15037 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15038 Don't assume glyph table len fits in int.

15040 (row_table_size): Now ptrdiff_t, not int.
15041 (scrolling_window): Avoid overflow in size calculations.
15042 Don't update size until allocation succeeds.
15043 * fns.c (concat): Check for overflow in size calculations.
15044 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15045 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15046 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15048 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15049 (get_doc_string): Check for size calculation overflow.
15050 Don't update size until allocation succeeds.
15051 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15052 EMACS_INT, where ptrdiff_t will do.
15053 (Fsubstitute_command_keys): Check for string overflow.
15055 * editfns.c (set_time_zone_rule): Don't assume environment length
15057 (message_length): Now ptrdiff_t, not int.
15058 (Fmessage_box): Don't update size until allocation succeeds.
15059 Don't assume message length fits in int.
15060 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15062 * emacs.c (main): Do not reallocate argv, since there is a null at
15063 the end that can be overwritten, and this way there's no need to
15064 worry about size-calculation overflow.
15065 (sort_args): Check for size-calculation overflow.
15067 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15069 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15071 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15072 (x_set_scroll_bar_width, x_figure_window_size):
15073 Check for integer overflow.
15074 (x_set_alpha): Do not assume XINT fits in int.
15076 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15077 This is for the members text_lines, text_cols, total_lines, total_cols,
15078 where the system imposes an 'int' limit.
15080 * fringe.c (Fdefine_fringe_bitmap):
15081 Don't update size until alloc works.
15083 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15084 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15086 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15087 Check for size-calculation overflow.
15088 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15089 do, as we prefer signed integers.
15090 (id_to_widget.max_size, id_to_widget.used)
15091 (xg_store_widget_in_map, xg_remove_widget_from_map)
15092 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15093 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15094 Use and return ptrdiff_t, not int.
15095 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15096 * gtkutil.h: Change prototypes to match the above.
15098 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15099 are duplicate now that they've been promoted to lisp.h.
15100 (x_allocate_bitmap_record, x_alloc_image_color)
15101 (make_image_cache, cache_image, xpm_load):
15102 Don't update size until alloc is done.
15103 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15105 Check for size calculation overflow.
15106 (ct_colors_allocated_max): New constant.
15107 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15110 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15111 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15112 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15113 Use ptrdiff_t, not int, to count maps.
15114 (read_char_minibuf_menu_prompt): Check for overflow in size
15115 calculations. Don't update size until allocation succeeds.
15116 Redo calculations to avoid overflow.
15117 * keyboard.h: Change prototypes to match the above.
15119 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15121 (current_minor_maps): Check for size calculation overflow.
15122 * keymap.h: Change prototypes to match the above.
15124 * lread.c (read1, init_obarray): Don't update size until alloc done.
15126 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15127 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15129 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15130 Now ptrdiff_t, not int.
15131 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
15132 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
15134 * process.c (Fnetwork_interface_list): Check for overflow
15135 in size calculation.
15137 * region-cache.c (move_cache_gap): Check for size calculation overflow.
15139 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
15140 overflow. Don't bother calling xmalloc when xrealloc will do.
15142 * search.c (Freplace_match): Check for size calculation overflow.
15143 (Fset_match_data): Don't assume list lengths fit in 'int'.
15145 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15146 for command line length. Do not attempt to address one before the
15147 beginning of an array, as that's not portable.
15149 * term.c (max_frame_lines): Remove; unused.
15150 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15152 (encode_terminal_code, calculate_costs): Check for size
15153 calculation overflow.
15154 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
15155 table lengths and related sizes. Don't update size until alloc
15156 done. Redo calculations to avoid overflow.
15157 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15159 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15160 subtracting pointers.

15164 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
15165 Don't update size until alloc done.
15166 Redo size calculations to avoid overflow.
15167 Check for size calculation overflow.
15168 (main) [DEBUG]: Fix typo in invoking tparam1.

15175 Use ptrdiff_t, not int, for sizes.
15176 (Finternal_make_lisp_face, cache_face):
15177 Check for size calculation overflow.
15178 (cache_face): Treat size calculation overflows as if they were
15179 memory exhaustion (the usual treatment), rather than aborting.
15181 * xfns.c (x_encode_text, x_set_name_internal)
15182 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15183 sizes, since they can exceed INT_MAX in size. Check for size
15184 calculation overflow.
15186 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15187 (xg_select): Check for size calculation overflow.
15188 Don't update size until alloc done.
15190 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15191 as sprintf is limited to int lengths.
15193 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15194 (X_LONG_MIN): New macros.
15195 Use them to make the following changes clearer.
15196 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15197 This change doesn't affect the value now, but it may help remind
15198 future maintainers not to raise the value too much later.
15199 (SELECTION_QUANTUM): Remove, replacing with ...
15200 (selection_quantum): ... new function, which avoids overflow.
15202 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15203 assumption that selection length fits in 'int'.
15204 (x_reply_selection_request, x_handle_selection_request)
15205 (x_get_window_property, receive_incremental_selection)
15206 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15207 (lisp_data_to_selection_data, clean_local_selection_data):

15209 (x_reply_selection_request, x_get_window_property)
15210 (receive_incremental_selection, x_property_data_to_lisp):
15211 Redo calculations to avoid overflow.
15212 (x_reply_selection_request): When sending hint, ceiling it at
15213 X_LONG_MAX rather than relying on wraparound overflow to send
15215 (x_get_window_property, receive_incremental_selection)
15216 (lisp_data_to_selection_data, x_property_data_to_lisp):
15217 Check for size-calculation overflow.
15218 (x_get_window_property, receive_incremental_selection)

15220 Don't store size until memory allocation succeeds.
15221 (x_get_window_property): Plug memory leak on memory exhaustion.
15222 Don't double-block input; malloc is safe here. Don't assume 2**34
15223 - 4 fits in unsigned long. Add an xassert to check
15224 XGetWindowProperty overflow. Be more careful about overflow
15225 calculations, and distinguish size from memory overflow better.
15226 (receive_incremental_selection): When tracing, don't assume
15227 unsigned int is less than INT_MAX.
15228 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15229 harmful) conversions of unsigned short to int.
15230 (lisp_data_to_selection_data): Don't assume that integers
15231 in the range -65535 through -1 fit in an X unsigned short.
15232 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15233 result parameters unless successful. Rely on cons_to_unsigned
15234 to report problems with elements; the old code wasn't right anyway.
15235 (x_check_property_data): Check for int overflow; we cannot use
15236 a wider type due to X limits.
15237 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15239 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15241 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15242 (x_term_init): Check for size calculation overflow.
15243 (x_color_cells): Don't store size until memory allocation succeeds.
15244 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15245 Don't assume alloca size is less than MAX_ALLOCA.
15246 (x_term_init): Don't assume length fits in int (sprintf is limited
15249 Use ptrdiff_t for composition IDs.
15250 * character.c (lisp_string_width):

15268 * image.c (xpm_get_color_table_h):
15269 * lisp.h (hash_lookup, hash_put):
15270 * minibuf.c (Ftest_completion):
15271 Use ptrdiff_t for hash table indexes, not int (which is too
15272 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15273 32-bit --with-wide-int hosts).
15275 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15276 Add a FIXME comment about memory leaks.
15277 (syms_of_charset): Don't assume xmalloc returns.

15281 * character.h (CHAR_WIDTH):
15282 * indent.c (MULTIBYTE_BYTES_WIDTH):
15283 Use sanitize_char_width to avoid undefined and/or bad behavior
15284 with outlandish widths.
15285 * character.h (sanitize_tab_width): Rename from sanitize_width,
15286 now that we have two such functions. All uses changed.

15297 * fileio.c: Integer overflow issues with file modes.
15298 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15300 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15301 Remove unreachable code.
15302 (read_hex, load_charset_map_from_file): Check for integer overflow.
15304 * xterm.c: Don't go over XClientMessageEvent limit.
15305 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15306 (x_send_scroll_bar_event): Likewise. Check that the size does not
15307 exceed limits imposed by XClientMessageEvent, as well as the usual
15308 ptrdiff_t and size_t limits.
15310 * keyboard.c: Overflow, signedness and related fixes.
15311 (make_lispy_movement): Use same integer type in forward decl
15312 that is used in the definition.
15313 (read_key_sequence, keyremap_step):
15314 Change bufsize argument back to int, undoing my 2011-03-30 change.
15315 We prefer signed types, and int is wide enough here.
15316 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15317 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15318 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15319 length, not size_t. Use ptrdiff_t for index, not int.
15320 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15321 possibility of integer overflow.
15323 Overflow, signedness and related fixes for images.
15325 * dispextern.h (struct it.stack[0].u.image.image_id)
15326 (struct_it.image_id, struct image.id, struct image_cache.size)

15333 * xdisp.c (calc_pixel_width_or_height):
15334 * xfns.c (image_cache_refcount):
15335 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

15344 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15345 (lookup_image): Remove unnecessary tests.
15346 (xbm_image_p): Locals are now of int, not EMACS_INT,
15347 since parse_image_check makes sure they fit into int.
15348 (png_load, gif_load, svg_load_image):
15349 Prefer int to unsigned where either will do.
15350 (tiff_handler): New function, combining the cores of the
15351 old tiff_error_handler and tiff_warning_handler.
15352 This function is rewritten to use vsnprintf and thereby avoid
15353 stack buffer overflows. It uses only the features of vsnprintf
15354 that are common to both POSIX and native Microsoft.
15355 (tiff_error_handler, tiff_warning_handler): Use it.
15356 (tiff_load, gif_load, imagemagick_load_image):
15357 Don't assume :index value fits in 'int'.
15358 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15359 (imagemagick_load_image): Check that crop parameters fit into
15360 the integer types that MagickCropImage accepts. Don't assume
15361 Vimagemagick_render_type has a nonnegative value. Don't assume
15362 size_t fits in 'long'.
15363 (gs_load): Use printmax_t to print the widest integers possible.
15364 Check for integer overflow when computing image height and width.
15366 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15368 * xdisp.c (redisplay_window): Don't force window start if point
15369 will be invisible in the resulting window. (Bug#9324)

15373 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15374 the display spec is of the form `(space ...)'.
15375 (handle_display_spec): Return the value returned by
15376 handle_single_display_spec, not just 1 or zero.
15377 (handle_single_display_spec): If the display spec is of the form
15378 `(space ...)', and specifies display in the text area, return 2
15380 (try_cursor_movement): Check for the need to scroll more
15381 accurately, and prefer exact match for point under bidi.
15382 Don't advance `row' beyond the last row of the window.
15384 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15385 into disp_prop; all users changed.
15387 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

15399 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15400 buffers, return left-to-right.
15401 (set_cursor_from_row): Consider candidate row a win if its glyph
15402 represents a newline and point is on that newline. Fixes cursor
15403 positioning on the newline at EOL of R2L text within L2R
15404 paragraph, and vice versa.
15405 (try_cursor_movement): Check continued rows, in addition to
15406 continuation rows. Fixes unwarranted scroll when point enters a
15407 continued line of R2L text within an L2R paragraph, or vice versa.
15408 (cursor_row_p): Consider the case of point being equal to
15409 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15410 from the end of a short line to the beginning of a continued line
15411 of R2L text within L2R paragraph.
15412 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15413 composed characters.

15433 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15435 * xdisp.c (redisplay_window): When computing centering_position,
15436 account for the height of the header line. (Bug#8874)
15438 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15439 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15440 candidate is selected by the mouse, and that candidate has a
15441 composed character under the mouse.
15443 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15444 coordinates reported by pos-visible-in-window-p for a composed
15445 character in column zero.
15447 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15449 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15451 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15453 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15454 consider it a hit if to_charpos is anywhere in the range of the
15455 composed buffer positions.
15457 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15459 * image.c (gif_load): Don't assume that each subimage has the same
15460 dimensions as the base image. Handle disposal method that is
15461 "undefined" by the gif spec (Bug#9335).
15463 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15465 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15470 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15471 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15472 from an Org mode buffer to a Speedbar frame.
15474 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15475 a composition, take its buffer position from IT->cmp_it.charpos.
15476 Fixes cursor positioning at the beginning of a line that begins
15477 with a composed character.
15479 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15481 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15482 character bidirectional type, use STRONG_L instead. Fixes crashes
15483 in a buffer produced by `describe-categories'.
15485 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15486 members before the level stack, so they would be saved and
15487 restored when copying iterator state. Fixes incorrect reordering
15488 around TABs covered by display properties.

15516 Fix memory allocation problems in Cygwin build (Bug#9273).
15518 * unexcw.c ( __malloc_initialized): Declare external variable.
15519 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15521 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15523 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

15562 * xdisp.c (move_it_in_display_line_to): Don't invoke
15563 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15564 ppos_it. Fixes vertical cursor motion when line beginning is
15565 covered by an image. (Bug#9296)
15567 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>

15576 the event loop. Get status from as_status (Bug#7276).
15578 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15579 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15580 the event loop (Bug#7276).

15603 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
15605 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15606 (Fnetwork_interface_list): Allocate in increments of bytes instead
15607 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15608 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15610 (struct ifflag_def): notrailers is smart on OSX.
15611 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15612 Get hardware address with getifaddrs if available.
15614 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15616 * xdisp.c (iterate_out_of_display_property): xassert that
15617 IT->position is set to within IT->object's boundaries. Break from
15618 the loop as soon as EOB is reached; avoids infloops in redisplay
15619 when IT->position is set up wrongly due to some bug.
15620 Set IT->current to match the bidi iterator unconditionally.
15621 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15622 entry. Force push_it to save on the stack the current
15623 buffer/string position, to be restored by pop_it. Fix flags in
15624 the iterator structure wrt the object coming from a display
15625 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15626 properties. (Bug#9284)
15628 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15630 * fontset.c (fontset_get_font_group): Add proper type checks.
15633 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15635 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
15636 and LC_VERSION_MIN_MACOSX.
15637 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
15638 (dump_it) [LC_FUNCTION_STARTS]: Use it.
15640 2011-08-08 Eli Zaretskii <eliz@gnu.org>
15642 * xdisp.c (forward_to_next_line_start): Allow to use the
15643 no-display-properties-and-no-overlays under bidi display.
15644 Set disp_pos in the bidi iterator to avoid searches for display
15645 properties and overlays.
15647 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15649 * editfns.c (Fset_time_zone_rule): Document relationship with the
15652 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
15653 the font entity extracted from the cache (Bug#8109).
15655 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15657 * composite.c (autocmp_chars): Don't reset point. That is done by
15658 restore_point_unwind (Bug#5984).
15660 2011-08-07 Juri Linkov <juri@jurta.org>
15662 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15663 to show the arg `TIME' instead of `TIMEVAL'.
15665 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15667 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15668 display property strides EOL and includes a newline, as in
15669 longlines-mode. (Bug#9254)
15670 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15671 word-wrap under bidirectional display. (Bug#9224)
15673 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15674 is non-zero, even if the data buffer is NULL. Fixes a crash in
15675 vertical-motion with longlines-mode. (Bug#9254)
15677 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15679 * bidi.c <bidi_cache_total_alloc>: Now static.
15680 (bidi_initialize): Initialize bidi_cache_total_alloc.
15682 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15685 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15686 amount allocated this far in `bidi_cache_total_alloc'.
15687 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15688 non-zero, only free the data buffer without restoring the cache
15689 contents. All callers changed.
15691 * dispextern.h (bidi_unshelve_cache): Update prototype.
15693 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15694 (move_it_in_display_line, move_it_to)
15695 (move_it_vertically_backward, move_it_by_lines): Replace the call
15696 to xfree to an equivalent call to bidi_unshelve_cache.
15697 (move_it_in_display_line_to): Fix logic of returning
15698 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15700 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15702 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15703 came from a string character with a `cursor' property. (Bug#9229)
15705 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15707 * Makefile.in (LIB_PTHREAD): New variable.
15708 (LIBES): Add LIB_PTHREAD (Bug#9216).
15710 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15711 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15713 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15715 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15717 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15719 * xterm.c (x_find_topmost_parent): New function.
15720 (x_set_frame_alpha): Find topmost parent window with
15721 x_find_topmost_parent and set the property there also (bug#9181).
15722 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15724 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15726 * callproc.c (Fcall_process): Avoid vfork clobbering
15727 the local vars buffer, coding_systems, current_dir.
15729 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15731 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15733 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15735 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15736 so that it is not optimized away.
15738 * xdisp.c (compute_display_string_pos): Remove unused local.
15740 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15742 Fix slow cursor motion and scrolling in large buffers with
15743 selective display, like Org Mode buffers. (Bug#9218)
15745 * dispextern.h (struct bidi_it): New member disp_prop_p.
15747 * xdisp.c: Remove one-slot cache of display string positions.
15748 (compute_display_string_pos): Accept an additional argument
15749 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15750 for a display string or property. If found, set DISP_PROP_P
15753 * bidi.c (bidi_fetch_char): Accept an additional argument
15754 DISP_PROP_P, and pass it to compute_display_string_pos.
15755 Only handle text covered by a display string if DISP_PROP_P is returned
15756 non-zero. All callers of bidi_fetch_char changed.
15758 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15760 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15762 2010-12-03 Don March <don@ohspite.net>
15764 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15765 last character M-[char] is translated to ESC [char] (bug#7541).
15767 2011-08-02 Kenichi Handa <handa@m17n.org>
15769 * lisp.h (uniprop_table): Extern it.
15771 * chartab.c (uniprop_table): Make it non-static.
15773 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15775 * xdisp.c (forward_to_next_line_start): Accept additional argument
15776 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15778 (reseat_at_next_visible_line_start): Use the bidi iterator state
15779 returned by forward_to_next_line_start to restore the state of
15780 it->bidi_it after backing up to previous newline. (Bug#9212)
15782 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15784 * regex.c (re_comp): Protoize.
15785 (re_exec): Fix return type.
15786 (regexec): Fix type of `ret'. (Bug#9203)
15788 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15790 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15791 This is needed if max-image-size is a floating-point number.
15793 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15795 * print.c (print_object): Print empty symbol as ##.
15797 * lread.c (read1): Read ## as empty symbol.
15799 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15801 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15802 setting frame foreground color (Bug#9175).
15803 (x_set_background_color): Likewise.
15805 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15806 contents (Bug#9176).
15807 (EmacsTooltip -init): Remove bezels and add shadows to
15810 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15811 or scroll bar (Bug#8470).
15813 * nsfont.m (nsfont_open): Remove assignment to voffset and
15814 unnecessary vars hshink, expand, hd, full_height, min_height.
15815 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15817 * nsterm.h (nsfont_info): Remove voffset field.
15819 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15821 Implement strike-through and overline on NextStep (Bug#8863).
15823 * nsfont.m (nsfont_open): Use underline position provided by font,
15824 instead of hard-coded value of 2.
15825 (nsfont_draw): Call ns_draw_text_decoration instead.
15827 * nsterm.h: Add declaration for ns_draw_text_decoration.
15829 * nsterm.m (ns_draw_text_decoration): New function for drawing
15830 underline, overline, and strike-through.
15831 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15832 ns_draw_text_decoration. Change treatment of cursor drawing to
15833 accommodate underlining, etc.
15835 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15837 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15840 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15842 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15843 Without this fix, if a signal arrives just after memory fills up,
15844 'malloc' might be invoked reentrantly.
15846 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15847 In other words, assume that every image size is allowed, on non-X
15848 hosts. This assumption is probably wrong, but it lets Emacs compile.
15850 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15852 * regex.c (re_iswctype): Convert return values to boolean.
15854 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15856 * xdisp.c (compute_display_string_pos): Don't use cached display
15857 string position if the buffer had its restriction changed.
15860 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15862 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15864 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15866 Integer signedness and overflow and related fixes. (Bug#9079)
15868 * bidi.c: Integer size and overflow fixes.
15869 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15870 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15871 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15872 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15873 (bidi_find_other_level_edge):
15874 Use ptrdiff_t instead of EMACS_INT where either will do.
15875 This works better on 32-bit hosts configured --with-wide-int.
15876 (bidi_cache_ensure_space): Check for size-calculation overflow.
15877 Use % rather than repeated addition, for better worst-case speed.
15878 Don't set bidi_cache_size until after xrealloc returns, because it
15880 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15881 (bidi_cache_ensure_space): Also check that the bidi cache size
15882 does not exceed that of the largest Lisp string or buffer. See Eli
15883 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15885 * alloc.c (__malloc_size_t): Remove.
15886 All uses replaced by size_t. See Andreas Schwab's note
15887 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15889 * image.c: Improve checking for integer overflow.
15890 (check_image_size): Assume that f is nonnull, since
15891 it is always nonnull in practice. This is one less thing to
15892 worry about when checking for integer overflow later.
15893 (x_check_image_size): New function, which checks for integer
15894 overflow issues inside X.
15895 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15896 This removes the need for a memory_full check.
15897 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15898 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15899 (xbm_read_bitmap_data): Change locals back to 'int', since
15900 their values must fit in 'int'.
15901 (xpm_load_image, png_load, tiff_load):
15902 Invoke x_create_x_image_and_pixmap earlier,
15903 to avoid much needless work if the image is too large.
15904 (tiff_load): Treat overly large images as if
15905 x_create_x_image_and_pixmap failed, not as malloc failures.
15906 (gs_load): Use x_check_image_size.
15908 * gtkutil.c: Omit integer casts.
15909 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15910 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15912 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15914 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15915 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15916 would wrongly return t on a 64-bit host.
15918 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15919 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15920 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15921 and therefore cause GCC to emit a bogus diagnostic in some cases.
15923 * image.c: Integer signedness and overflow and related fixes.
15924 This is not an exhaustive set of fixes, but it's time to
15925 record what I've got.
15926 (lookup_pixel_color, check_image_size): Remove redundant decls.
15927 (check_image_size): Don't assume that arbitrary EMACS_INT values
15928 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15929 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15930 (tiff_load, imagemagick_load_image):
15931 Check for overflow in size calculations.
15932 (x_create_x_image_and_pixmap): Remove unnecessary test for
15933 xmalloc returning NULL; that can't happen.
15934 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15935 (xpm_color_bucket): Use better integer hashing function.
15936 (xpm_cache_color): Don't possibly over-allocate memory.
15937 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15938 (gif_memory_source):
15939 Use ptrdiff_t, not int or size_t, to record sizes.
15940 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15941 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15942 either works, as we prefer signed integers.
15943 (tiff_read_from_memory, tiff_write_from_memory):
15944 Return tsize_t, not size_t, since that's what the TIFF API wants.
15945 (tiff_read_from_memory): Don't fail simply because the read would
15946 go past EOF; instead, return a short read.
15947 (tiff_load): Omit no-longer-needed casts.
15948 (Fimagemagick_types): Don't assume size fits into 'int'.
15950 Improve hashing quality when configured --with-wide-int.
15951 * fns.c (hash_string): New function, taken from sxhash_string.
15952 Do not discard information about ASCII character case; this
15953 discarding is no longer needed.
15954 (sxhash-string): Use it. Change sig to match it. Caller changed.
15955 * lisp.h: Declare it.
15956 * lread.c (hash_string): Remove, since we now use fns.c's version.
15957 The fns.c version returns a wider integer if --with-wide-int is
15958 specified, so this should help the quality of the hashing a bit.
15960 * emacs.c: Integer overflow minor fix.
15961 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15962 Define only if GNU_LINUX.
15963 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15965 * dispnew.c: Integer signedness and overflow fixes.
15966 Remove unnecessary forward decls, that were a maintenance hassle.
15967 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15969 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15970 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15971 (prepare_desired_row, line_draw_cost):
15972 Use int, not unsigned, where either works.
15973 (save_current_matrix, restore_current_matrix):
15974 Use ptrdiff_t, not size_t, where either works.
15975 (init_display): Check for overflow more accurately, and without
15976 relying on undefined behavior.
15978 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15979 Remove, replacing with the new symbols in lisp.h. All uses changed.
15980 * fileio.c (make_temp_name):
15981 * filelock.c (lock_file_1, lock_file):
15982 * xdisp.c (message_dolog):
15983 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15984 Use pMd etc. instead.
15985 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15986 replacing the pWIDE etc. symbols removed from editfns.c.
15988 * keyboard.h (num_input_events): Now uintmax_t.
15989 This is (very slightly) less likely to mess up due to wraparound.
15992 * buffer.c: Integer signedness fixes.
15993 (alloc_buffer_text, enlarge_buffer_text):
15994 Use ptrdiff_t rather than size_t when either will do, as we prefer
15997 * alloc.c: Integer signedness and overflow fixes.
15998 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15999 (__malloc_size_t): Default to size_t, not to int.
16000 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16001 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16002 Prefer ptrdiff_t to size_t when either would do, as we prefer
16004 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16005 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16006 Now const. Initialize with values that are in range even if char
16008 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16009 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16010 These functions do the right thing with sizes > 2**32.
16011 (check_depth): Now ptrdiff_t, not int.
16012 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16013 Adjust to new way of storing sizes. Check for size overflow bugs
16015 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16016 slightly wrong anyway, as it missed one instance of
16017 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16018 (refill_memory_reserve): Omit needless cast to size_t.
16019 (mark_object_loop_halt): Mark as externally visible.
16021 * xselect.c: Integer signedness and overflow fixes.
16022 (Fx_register_dnd_atom, x_handle_dnd_message):
16023 Use ptrdiff_t, not size_t, since we prefer signed.
16024 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16025 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16026 x_dnd_atoms_size and x_dnd_atoms_length.
16028 * doprnt.c: Prefer signed to unsigned when either works.
16030 * doprnt.c (doprnt):
16032 * xdisp.c (vmessage):
16033 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16034 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16035 prefer signed arithmetic to avoid comparison confusion.
16036 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16037 but is a bit tricky.
16039 Assume freestanding C89 headers, string.h, stdlib.h.
16040 * data.c, doprnt.c, floatfns.c, print.c:
16041 Include float.h unconditionally.
16042 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16043 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16044 * regex.c: Likewise for stddef.h, string.h.
16045 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16046 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16047 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16048 (STDC_HEADERS): Remove obsolete defines.
16049 * sysdep.c: Include limits.h unconditionally.
16051 Assume support for memcmp, memcpy, memmove, memset.
16052 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16053 * regex.c (memcmp, memcpy):
16054 Remove; we assume C89 now.
16056 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16057 (__malloc_safe_bcopy): Remove; no longer needed.
16059 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16060 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16061 well either way, and we prefer signed to unsigned.
16063 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16065 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16066 closes the connection while we're reading (bug#9182).
16068 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16070 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16071 are specified (Bug#9168).
16073 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16075 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16076 Found by GCC static checking and --with-wide-int on a 32-bit host.
16078 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16080 * xdisp.c (compute_display_string_pos): Fix logic of caching
16081 previous display string position. Initialize cached_prev_pos to
16082 -1. Fixes slow-down at the beginning of a buffer.
16084 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16086 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16087 for attrs[LFACE_FONTSET_INDEX].
16089 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16091 * xml.c (parse_region): Remove unused local
16092 that was recently introduced.
16094 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16096 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16097 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16099 * xdisp.c (move_it_in_display_line_to): Record the best matching
16100 position for TO_CHARPOS while scanning the line, and restore it on
16101 exit if none of the characters scanned was an exact match.
16102 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16103 when exact match is impossible due to invisible text, and the
16104 lines are truncated.
16106 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16108 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16111 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16113 Fix a significant slow-down of cursor motion with C-n, C-p,
16114 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16115 auto-repeat under bidi redisplay in fontified buffers.
16116 * xdisp.c (compute_stop_pos_backwards): New function.
16117 (next_element_from_buffer): Call compute_stop_pos_backwards to
16118 find a suitable prev_stop when we find ourselves before
16120 (reseat): Don't look for prev_stop, as that could mean a very long
16122 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16123 <cached_disp_overlay_modiff>: Cache for last found display string
16125 (compute_display_string_pos): Return the cached position if asked
16126 about the same buffer in the same area of character positions, and
16127 the buffer wasn't changed since the time the display string
16128 position was cached.
16130 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16132 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16133 is an integer, which is important for empty lines. (Bug#9149)
16135 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16137 * frame.c (Fmodify_frame_parameters): In tty case, update the
16138 default face if necessary (Bug#4238).
16140 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16142 * editfns.c (Fstring_to_char): No need to explain what a character
16143 is in the docstring (Bug#6576).
16145 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16147 * xml.c (parse_region): Make sure we always return a tree.
16149 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16151 * xml.c (parse_region): If a document contains only comments,
16154 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16156 * xml.c (make_dom): Return comments, too.
16158 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16161 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16162 and the surrounding thread.
16163 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16164 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16165 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16167 * s/openbsd.h (BROKEN_SIGIO): Define.
16168 * unexelf.c (unexec) [__OpenBSD__]:
16169 Don't update the .mdebug section of the Alpha COFF symbol table.
16171 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16173 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16176 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16178 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16179 This fixes some race conditions on the permissions of any newly
16182 * alloc.c (valid_pointer_p): Use pipe, not open.
16183 This fixes some permissions issues when debugging.
16185 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16186 If fchown fails to set both uid and gid, try to set just gid,
16187 as that is sometimes allowed. Adjust the file's mode to eliminate
16188 setuid or setgid bits that are inappropriate if fchown fails.
16190 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16192 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16193 to compare Lisp_Objects.

16198 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16200 * lread.c (read_integer): Unread even EOF character.
16201 (read1): Likewise. Properly record start position of symbol.
16203 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16204 symbol character follows.
16206 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16208 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16209 This works around a problem with the previous change to Fcopy_file.
16210 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16211 and without this change, GCC might complain about discarding
16212 fchown's return value.
16214 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16216 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16218 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16220 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16222 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16224 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16225 it's used from the C level.
16227 * process.c: Use the same condition for POLL_FOR_INPUT in both
16228 keyboard.c and process.c (bug#1858).
16230 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16232 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16233 (Fgnutls_boot): Use it.
16235 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16237 * doc.c (Fsubstitute_command_keys): Revert last change.
16239 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16241 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16242 quotes the next character, and doesn't affect other longer
16243 sequences (bug#8935).
16245 * lread.c (syms_of_lread): Clarify that is isn't only
16246 `eval-buffer' and `eval-defun' that's affected by
16247 `lexical-binding' (bug#8460).
16249 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16251 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16252 bidi redisplay when a line includes both an image and is truncated.
16254 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16256 Fix minor problems found by static checking.
16257 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16258 (elsz): Now a signed constant, not a size_t var. We prefer signed
16259 types to unsigned, to avoid integer comparison confusion. Without
16260 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16261 "cannot optimize loop, the loop counter may overflow", a symptom
16263 * indent.c (Fvertical_motion): Mark locals as initialized.
16264 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16266 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16268 * search.c (Fre_search_backward): Mention `case-fold-search' in
16269 all the re_search_* functions (bug#8138).

16289 buffer position was specified. Initialize paragraph_embedding to
16291 (reseat_to_string): Initialize the bidi iterator.
16292 (display_string): If we need to ignore text properties of
16293 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16294 original value of -1 will not work with bidi.)
16295 (compute_display_string_pos): First arg is now struct
16296 `text_pos *'; all callers changed. Support display properties on
16298 (compute_display_string_end): Support display properties on Lisp
16300 (init_iterator, reseat_1, reseat_to_string): Initialize the
16301 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16302 when iterating on a string not from display properties).
16303 (compute_display_string_pos, compute_display_string_end):
16304 Fix calculation of the object to scan. Fixes an error when using
16306 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16307 base_level_stop; instead, set base_level_stop to BEGV.
16308 Fixes crashes in vertical-motion.
16309 (next_element_from_buffer): Improve commentary for when
16310 the iterator is before prev_stop.
16311 (init_iterator): Initialize bidi_p from the default value of
16312 bidi-display-reordering, not from buffer-local value. Use the
16313 buffer-local value only if initializing for buffer iteration.
16314 (handle_invisible_prop): Support invisible properties on strings
16315 that are being bidi-reordered.
16316 (set_iterator_to_next): Support bidi reordering of C strings and
16318 (next_element_from_string): Support bidi reordering of Lisp

16322 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16323 (init_iterator): Don't initialize it->bidi_p for strings
16325 (reseat_to_string): Initialize it->bidi_p for strings here.

16332 character that is not the first one in the visual order.
16333 (get_visually_first_element): New function, refactored from common
16334 parts of next_element_from_buffer, next_element_from_string, and
16335 next_element_from_c_string.
16336 (tool_bar_lines_needed, redisplay_tool_bar)
16337 (display_menu_bar): Force left-to-right direction. Add a FIXME
16338 comment for making that be controlled by a user option.
16339 (push_it, pop_it): Save and restore the state of the
16340 bidi iterator. Save and restore the bidi_p flag.
16341 (pop_it): Iterate out of display property for string iteration as
16343 (iterate_out_of_display_property): Support iteration over strings.
16344 (handle_single_display_spec): Set up it->bidi_it for iteration
16345 over a display string, and call bidi_init_it.
16346 (handle_single_display_spec, next_overlay_string)
16347 (get_overlay_strings_1, push_display_prop): Set up the bidi
16348 iterator for displaying display or overlay strings.
16349 (forward_to_next_line_start): Don't use the shortcut if
16351 (back_to_previous_visible_line_start): If handle_display_prop
16352 pushed the iterator stack, restore the internal state of the bidi
16353 iterator by calling bidi_pop_it same number of times.
16354 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16355 and we are bidi-iterating, don't decrement the iterator position;
16356 instead, set the first_elt flag in the bidi iterator, to produce
16358 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16359 (push_display_prop): xassert that we are iterating a buffer.
16360 (push_it, pop_it): Save and restore paragraph_embedding member.
16361 (handle_single_display_spec, next_overlay_string)
16362 (get_overlay_strings_1, reseat_1, reseat_to_string)
16363 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16364 correctly. Don't assume unibyte strings are not bidi-reordered.
16365 (compute_display_string_pos)
16366 (compute_display_string_end): Fix handling the case of C string.
16367 (push_it, pop_it): Save and restore from_disp_prop_p.

16373 property. Fix a typo in popping stretch info. Add an assertion
16374 for verifying that the iterator position is in sync with the bidi
16376 (handle_single_display_spec, get_overlay_strings_1)
16377 (push_display_prop): Fix initialization of paragraph direction for
16378 string when that of the parent object is not yet determined.

16390 (try_scrolling, redisplay_window, display_line): Use them when
16391 saving a temporary copy of the iterator and restoring it back.
16392 (back_to_previous_visible_line_start, reseat_1)

16394 (move_it_in_display_line_to): If iterator ended up at
16395 EOL, but we never saw any buffer positions smaller than
16396 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16397 motion in bidi-reordered lines.

16399 immediately before the call to set_iterator_to_next. Fixes cursor
16400 motion in bidi-reordered lines with stretch glyphs and strings
16401 displayed in margins. (Bug#8133) (Bug#8867)
16402 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16404 (pos_visible_p): Support positions in bidi-reordered lines.
16405 Save and restore bidi cache.
16407 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16408 (bidi_paragraph_info): Delete unused struct.
16409 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
16410 (bidi_cache_start): New variable.

16426 Support iteration over a string.
16427 (bidi_set_sor_type, bidi_resolve_explicit_1)
16428 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16429 can now be zero (for strings); special values 0 and -1 were
16430 changed to -1 and -2, respectively.
16431 (bidi_char_at_pos): New function.
16432 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16520 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16521 The old code sometimes used this field without initializing it.
16523 * alloc.c (gc_sweep): Don't read past end of array.
16524 In theory, the old code could also have corrupted Emacs internals,
16525 though it'd be very unlikely.

16792 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

16830 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16831 subseconds part to the entropy, as that's a bit more random.
16832 Prefer signed to unsigned, since the signedness doesn't matter and
16833 in general we prefer signed. When given a limit, use a
16834 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16835 latter isn't right if USE_2_TAGS_FOR_INTS.
16836 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16837 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16849 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16850 This is more efficient than Ffile_directory_p and avoids a minor race.
16852 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16854 * buffer.c (Foverlay_put): Say what the return value is
16857 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16858 is a directory before asking whether to use the file name

16861 error be more correct.
16863 * fns.c (Frequire): Remove the mention of the .gz files, since
16864 that's installation-specific, but keep the mention of

16880 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16881 Also (re)move comments that are misplaced or no longer relevant.

16910 * lread.c (syms_of_lread): Mention single symbols defined by

16982 * eval.c (struct backtrace): Simplify and port the data structure.
16983 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16984 signed bit field, as this assumption is not portable and it makes
16985 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16986 "char debug_on_exit : 1" as this is not portable either; instead,
16987 use the portable "unsigned int debug_on_exit : 1". Remove unused
16988 member evalargs. Remove obsolete comments about cc bombing out.
16990 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
16992 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

17060 (emacs_fixed_get_preferred_height): Use min_width/height from
17061 frames size_hint to set minimum and natural (Bug#8919).
17062 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17063 and use min_width/height from frames size_hint to set
17064 min_width/height (Bug#8919).

17084 Use gnulib's dup2 module instead of rolling our own.
17085 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

17156 * print.c (printchar, strout): Check for string overflow.
17157 (PRINTPREPARE, printchar, strout):
17158 Don't set size unless allocation succeeds.
17160 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17161 for sizes. Check for string overflow more accurately.

17165 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17166 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17170 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17172 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17174 * lread.c: Integer overflow fixes.
17175 (read_integer): Radix is now EMACS_INT, not int,
17176 to improve quality of diagnostics for out-of-range radices.
17177 Calculate buffer size correctly for out-of-range radices.
17178 (read1): Check for integer overflow in radices, and in
17179 read-circle numbers.
17180 (read_escape): Avoid int overflow.
17181 (Fload, openp, read_buffer_size, read1)
17182 (substitute_object_recurse, read_vector, read_list, map_obarray):
17183 Use ptrdiff_t, not int, for sizes.

17198 2011-06-22 Leo Liu <sdl.web@gmail.com>
17200 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17201 Move to minibuffer.el.
17203 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17205 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17206 The following patches are for when GLYPH_DEBUG && !XASSERT.
17207 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17208 * dispnew.c (flush_stdout):
17209 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17210 Mark as externally visible.
17211 * dispnew.c (check_window_matrix_pointers): Now static.
17212 * dispnew.c (window_to_frame_vpos):
17213 * xfns.c (unwind_create_frame):

17219 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17220 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17222 (debug_method_add): Use va_list and vsprintf rather than relying
17223 on undefined behavior with wrong number of arguments.
17224 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17225 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17226 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17227 since we're not interested in debugging glyphs with old libraries.
17228 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17229 GCC 4.6.0's static checking.
17231 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

17245 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17247 * xfaces.c (load_pixmap):

17249 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17250 (.bitmaps_last, struct x_output.icon_bitmap):
17251 Use ptrdiff_t, not int, for bitmap indexes.
17252 (x_allocate_bitmap_record): Check for size overflow.

17265 Use ptrdiff_t, not int, for sizes.
17266 (overlays_at, overlays_in): Check for size-calculation overflow.
17268 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17270 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17271 (x_session_initialize): Do not assume string length fits in int.
17273 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17274 This is unlikely, but can occur if DPI is outlandish.
17276 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17277 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17279 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17280 * xrdb.c (magic_file_p, search_magic_path):
17281 Omit last arg SUFFIX; it was always 0. All callers changed.
17282 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17284 * xfont.c (xfont_match): Avoid need for strlen.

17289 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17290 not unsigned long, as we prefer signed integers. All callers changed.
17291 Detect integer overflow in repeat count.
17292 (message_dolog): Don't assume print length fits in 39 bytes.
17293 (display_mode_element): Don't assume strlen fits in int.
17295 * termcap.c: Don't assume sizes fit in int and never overflow.
17296 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17297 (gobble_line): Check for size-calculation overflow.
17299 * minibuf.c (Fread_buffer):
17300 * lread.c (intern, intern_c_string):
17301 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

17318 (lock_info_type, lock_file_1, lock_file):
17319 Don't assume pid_t and time_t fit in unsigned long.
17320 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17321 (current_lock_owner): Prefer signed type for sizes.
17322 Use memcpy, not strncpy, where memcpy is what is really wanted.
17323 Don't assume (via atoi) that time_t and pid_t fit in int.
17324 Check for time_t and/or pid_t out of range, e.g., via a network share.
17325 Don't alloca where an auto var works fine.
17327 * fileio.c: Fix some integer overflow issues.
17328 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):

17330 (directory_file_name): Don't assume string length fits in long.
17331 (make_temp_name): Don't assume pid fits in int, or that its print
17332 length is less than 20.

17351 (Fgetenv_internal):
17352 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17354 * lread.c (invalid_syntax): Omit length argument.
17355 All uses changed. This doesn't fix a bug, but it simplifies the
17356 code away from its former Hollerith-constant appearance, and it's
17357 one less 'int' to worry about when looking at integer-overflow issues.
17358 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17360 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17361 This didn't break anything, but it didn't help either.
17362 It's confusing to put a bogus integer in a place where the actual
17363 value does not matter.
17364 (LIST_END_P): Remove unused macro and its bogus comment.
17365 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17367 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17368 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17370 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17371 We prefer signed types, and the value cannot exceed the EMACS_INT
17372 range anyway (because otherwise the length would not be representable).
17373 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17374 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17375 This avoids a GCC warning when WIDE_EMACS_INT.
17377 * indent.c (sane_tab_width): New function.
17378 (current_column, scan_for_column, Findent_to, position_indentation)
17379 (compute_motion): Use it. This is just for clarity.
17380 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17382 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17384 * lisp.h (lint_assume): New macro.
17385 * composite.c (composition_gstring_put_cache):
17386 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17388 * editfns.c, insdel.c:
17389 Omit unnecessary forward decls, to simplify future changes.
17391 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17393 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17395 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17396 Use much-faster test for byte-length change.
17397 Don't assume string byte-length fits in 'int'.
17398 Check that character arg fits in 'int'.
17399 (mapcar1): Declare byte as byte, for clarity.
17401 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17403 * fns.c (concat): Catch string overflow earlier.
17404 Do not rely on integer wraparound.
17406 * dispextern.h (struct it.overlay_strings_charpos)
17407 (struct it.selective): Now EMACS_INT, not int.
17408 * xdisp.c (forward_to_next_line_start)
17409 (back_to_previous_visible_line_start)
17410 (reseat_at_next_visible_line_start, next_element_from_buffer):
17411 Don't arbitrarily truncate the value of 'selective' to int.
17413 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17415 * composite.c: Don't truncate sizes to 'int'.
17416 (composition_gstring_p, composition_reseat_it)
17417 (composition_adjust_point): Use EMACS_INT, not int.
17418 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17419 not EMACS_UINT, for indexes.
17421 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17423 * buffer.c: Include <verify.h>.
17424 (struct sortvec.priority, struct sortstr.priority):
17425 Now EMACS_INT, not int.
17426 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17427 (struct sortstr.size, record_overlay_string)
17428 (struct sortstrlist.size, struct sortlist.used):
17429 Don't truncate size to int.
17430 (record_overlay_string): Check for size-calculation overflow.
17431 (init_buffer_once): Check at compile-time, not run-time.
17433 2011-06-22 Jim Meyering <meyering@redhat.com>
17435 Don't leak an XBM-image-sized buffer
17436 * image.c (xbm_load): Free the image buffer after using it.
17438 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17441 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17442 that Sun C diagnosed.
17443 * fns.c (secure_hash): Fix pointer signedness issue.
17444 * intervals.c (static_offset_intervals): New function.
17445 (offset_intervals): Use it.
17447 2011-06-21 Leo Liu <sdl.web@gmail.com>
17450 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17453 * fns.c (secure_hash): Rename from crypto_hash_function and change
17454 the first arg to accept symbols.
17455 (Fsecure_hash): New primitive.
17456 (syms_of_fns): New symbols.
17458 2011-06-20 Deniz Dogan <deniz@dogan.se>
17460 * process.c (Fset_process_buffer): Clarify return value in
17463 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17465 * dispnew.c (add_window_display_history): Use BVAR.
17467 * xdisp.c (debug_method_add): Use BVAR.
17468 (check_window_end, dump_glyph_matrix, dump_glyph)
17469 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17471 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17474 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17475 check till after the cache is created in init_frame_faces.
17477 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17479 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17481 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17483 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17484 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17485 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17487 Improve buffer-overflow checking (Bug#8873).
17488 * fileio.c (Finsert_file_contents):
17489 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17490 Remove the old (too-loose) buffer overflow checks.
17491 They weren't needed, since make_gap checks for buffer overflow.
17492 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17493 The old code merely checked for Emacs fixnum overflow, and relied
17494 on undefined (wraparound) behavior. The new code avoids undefined
17495 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17497 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17498 Tune. Don't use wider integers than needed. Don't use alloca.
17499 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17501 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17503 * insdel.c, lisp.h (buffer_overflow): New function.
17504 (insert_from_buffer_1, replace_range, replace_range_2):
17505 * insdel.c (make_gap_larger):
17506 * editfns.c (Finsert_char):
17507 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17509 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17511 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17513 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17515 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17516 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17518 * fileio.c: Don't assume EMACS_INT fits in off_t.
17519 (emacs_lseek): New static function.
17520 (Finsert_file_contents, Fwrite_region): Use it.
17521 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17523 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17525 * fns.c: Don't overflow int when computing a list length.
17526 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17527 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17528 truncation on 64-bit hosts. Check for QUIT every
17529 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17530 faster and is responsive enough.
17531 (Flength): Report an error instead of overflowing an integer.
17532 (Fsafe_length): Return a float if the value is not representable
17533 as a fixnum. This shouldn't happen except in contrived situations.
17534 (Fnthcdr, Fsort): Don't assume list length fits in int.
17535 (Fcopy_sequence): Don't assume vector length fits in int.
17537 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17538 (header_size, word_size): New constants.
17539 (allocate_vectorlike): Don't check size overflow here.
17540 (allocate_vector): Check it here instead, since this is the only
17541 caller of allocate_vectorlike that could cause overflow.
17542 Check that the new vector's length is representable as a fixnum.
17544 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17545 The previous code was bogus. For example, next_almost_prime (32)
17546 returned 39, which is undesirable as it is a multiple of 3; and
17547 next_almost_prime (24) returned 25, which is a multiple of 5 so
17548 why was the code bothering to check for multiples of 7?
17550 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17552 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17554 Variadic C functions now count arguments with ptrdiff_t.
17555 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17556 Back then I didn't know that the Emacs coding style prefers signed int.
17557 Also, in the meantime I found a few more instances where arguments
17558 were being counted with int, which may truncate counts on 64-bit
17559 machines, or EMACS_INT, which may be unnecessarily wide.
17560 * lisp.h (struct Lisp_Subr.function.aMANY)
17561 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17562 Arg counts are now ptrdiff_t, not size_t.
17563 All variadic functions and their callers changed accordingly.
17564 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17565 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17566 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17567 * callint.c (Fcall_interactively): Check arg count for overflow,
17568 to avoid potential buffer overrun. Use signed char, not 'int',
17569 for 'varies' array, so that we needn't bother to check its size
17570 calculation for overflow.
17571 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17572 * eval.c (apply_lambda):
17573 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17574 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17575 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17577 * callint.c (Fcall_interactively): Don't use index var as event count.
17579 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17580 * mem-limits.h (SIZE): Remove; no longer used.
17582 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17584 Remove unnecessary casts.
17585 * xterm.c (x_term_init):
17586 * xfns.c (x_set_border_pixel):
17587 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17588 These aren't needed now that we assume ANSI C.
17590 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17591 It's more likely to cause problems (due to unsigned overflow)
17594 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17596 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17598 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17600 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17602 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17604 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17606 GLYPH_CODE_FACE returns EMACS_INT, not int.
17607 * dispextern.h (merge_faces):
17608 * xfaces.c (merge_faces):
17609 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17610 Don't assume EMACS_INT fits in int.
17612 * character.h (CHAR_VALID_P): Remove unused parameter.
17613 * fontset.c, lisp.h, xdisp.c: All uses changed.
17615 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17617 * fns.c (concat): Minor tuning based on overflow analysis.
17618 This doesn't fix any bugs. Use int to hold character, instead
17619 of constantly refetching from Emacs object. Use XFASTINT, not
17620 XINT, for value known to be a character. Don't bother comparing
17621 a single byte to 0400, as it's always less.
17623 * floatfns.c (Fexpt):
17624 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17626 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17629 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17631 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17632 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17633 incorrectly succeed when S was a string, because 4294967386 was
17634 truncated before it was used.
17636 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17637 Otherwise, an out-of-range integer could cause undefined behavior
17640 * composite.c: Use int, not EMACS_INT, for characters.
17641 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17642 EMACS_INT, for values that are known to be in character range.
17643 This doesn't fix any bugs but is the usual style inside Emacs and
17644 may generate better code on 32-bit machines.
17646 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17647 This is for reasons similar to the recent CHAR_STRING fix.
17648 * charset.c (Fencode_char): Check that character arg is actually
17649 a character. Pass an int to ENCODE_CHAR.
17650 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17651 wider than 'int', as a compile-time check to prevent future regressions
17654 * character.c (char_string): Remove unnecessary casts.
17656 Make sure a 64-bit char is never passed to CHAR_STRING.
17657 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17658 by silently ignoring the top 32 bits, allowing some values
17659 that were far too large to be valid characters.
17660 * character.h: Include <verify.h>.
17661 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17662 arguments are no wider than unsigned, as a compile-time check
17663 to prevent future regressions in this area.
17665 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17666 (Fsubst_char_in_region):
17668 * xdisp.c (decode_mode_spec_coding):
17669 Adjust to CHAR_STRING's new requirement.
17670 * editfns.c (Finsert_char, Fsubst_char_in_region):
17671 * fns.c (concat): Check that character args are actually
17672 characters. Without this test, these functions did the wrong
17673 thing with wildly out-of-range values on 64-bit hosts.
17675 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17676 These casts should not be needed on 32-bit hosts, either.
17677 * keyboard.c (read_char):
17678 * lread.c (Fload): Remove casts to unsigned.
17680 * lisp.h (UNSIGNED_CMP): New macro.
17681 This fixes comparison bugs on 64-bit hosts.
17682 (ASCII_CHAR_P): Use it.
17683 * casefiddle.c (casify_object):
17684 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17685 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17686 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17687 * dispextern.h (FACE_FROM_ID):
17688 * keyboard.c (read_char): Use UNSIGNED_CMP.
17690 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17691 not to EMACS_INT, to avoid GCC warning.
17693 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17695 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17696 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17697 isn't needed on 32-bit machines.
17699 * buffer.c (Fgenerate_new_buffer_name):
17700 Use EMACS_INT for count, not int.
17701 (advance_to_char_boundary): Return EMACS_INT, not int.
17703 * data.c (Qcompiled_function): Now static.
17705 * window.c (window_body_lines): Now static.
17707 * image.c (gif_load): Rename local to avoid shadowing.
17709 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17710 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17711 * alloc.c (make_save_value): Integer argument is now of type
17712 ptrdiff_t, not int.
17713 (mark_object): Use ptrdiff_t, not int.
17714 * lisp.h (pD): New macro.
17715 * print.c (print_object): Use it.
17717 * alloc.c: Use EMACS_INT, not int, to count objects.
17718 (total_conses, total_markers, total_symbols, total_vector_size)
17719 (total_free_conses, total_free_markers, total_free_symbols)
17720 (total_free_floats, total_floats, total_free_intervals)
17721 (total_intervals, total_strings, total_free_strings):
17722 Now EMACS_INT, not int. All uses changed.
17723 (Fgarbage_collect): Compute overall total using a double, so that
17724 integer overflow is less likely to be a problem. Check for overflow
17725 when converting back to an integer.
17726 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17727 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17728 These were 'int' variables that could overflow on 64-bit hosts;
17729 they were never used, so remove them instead of repairing them.
17730 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17731 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17732 Previously, this ceilinged at INT_MAX, but that doesn't work on
17734 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17736 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17737 (allocate_vectorlike): Check for ptrdiff_t overflow.
17738 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17739 when a (possibly-narrower) signed value would do just as well.
17740 We prefer using signed arithmetic, to avoid comparison confusion.
17742 * alloc.c: Catch some string size overflows that we were missing.
17743 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17744 for convenience in STRING_BYTES_MAX.
17745 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17746 The definition here is exact; the one in lisp.h was approximate.
17747 (allocate_string_data): Check for string overflow. This catches
17748 some instances we weren't catching before. Also, it catches
17749 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17750 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17751 and ptrdiff_t and EMACS_INT are both 64 bits.
17753 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17754 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17755 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17757 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17759 * alloc.c (Fmake_string): Check for out-of-range init.
17761 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17763 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17765 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17767 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17768 xg_get_default_scrollbar_width.
17770 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17771 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17772 (style_changed_cb): Call update_theme_scrollbar_width and call
17773 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17774 all frames (Bug#8505).
17775 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17776 Call gtk_window_set_resizable if HAVE_GTK3.
17777 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17778 and height if HAVE_GTK3 (Bug#8505).
17779 (scroll_bar_width_for_theme): New variable.
17780 (update_theme_scrollbar_width): New function.
17781 (xg_get_default_scrollbar_width): Move code to
17782 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17783 (xg_initialize): Call update_theme_scrollbar_width.
17785 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17787 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17789 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17791 * frame.c (make_frame): Call other_buffer_safely instead of
17794 * window.c (temp_output_buffer_show): Call display_buffer with
17795 second argument Vtemp_buffer_show_specifiers and reset latter
17796 immediately after the call.
17797 (Vtemp_buffer_show_specifiers): New variable.
17798 (auto_window_vscroll_p, next_screen_context_lines)
17799 (Vscroll_preserve_screen_position): Remove leading asterisks from
17802 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>

18247 (Fframe_root_window, Fframe_first_window)
18248 (Fframe_selected_window): Move here from frame.c. Accept frame
18249 or arbitrary window as argument. Update doc-strings.
18250 (Fminibuffer_window): Move up in code.
18251 (Fwindow_minibuffer_p): Move up in code and simplify.
18252 (Fset_frame_selected_window): Move here from frame.c.
18254 (Fselected_window, select_window, Fselect_window): Move up in
18255 code. Minor doc-string fixes.
18257 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18259 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18260 Do not assume that spare memory exists; that assumption is valid
18261 only if SYSTEM_MALLOC.
18262 (LARGE_REQUEST): New macro, so that the issue of large requests
18263 is separated from the issue of spare memory.
18265 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
18267 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

18282 min width by calling x_set_scroll_bar_default_width (Bug#8505).
18284 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
18286 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
18288 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

18292 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
18293 New error handlers.
18294 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18295 Obey Vx_select_enable_clipboard_manager. Catch errors in
18296 x_clipboard_manager_save (Bug#8779).
18297 (Vx_select_enable_clipboard_manager): New variable.
18298 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18300 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18302 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18304 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18306 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18307 in the current matrix if keep_current_p is non-zero.

18311 * bidi.c (bidi_level_of_next_char): Fix last change.
18313 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18315 Support bidi reordering of text covered by display properties.
18317 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18318 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18319 (bidi_cache_search, bidi_cache_iterator_state)
18320 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18321 (bidi_level_of_next_char, bidi_move_to_visually_next):
18322 Support character positions inside a run of characters covered by a
18324 (bidi_paragraph_init, bidi_resolve_explicit_1)
18325 (bidi_level_of_next_char): Call bidi_fetch_char and
18326 bidi_fetch_char_advance instead of FETCH_CHAR and
18327 FETCH_CHAR_ADVANCE.

18329 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18331 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18332 instead of using explicit *_CHAR codes.
18333 (bidi_resolve_explicit, bidi_resolve_weak):
18334 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18335 bidirectional text is supported only in multibyte buffers.
18336 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18337 it to initialize the frame_window_p member of struct bidi_it.
18338 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18339 (bidi_resolve_explicit, bidi_resolve_weak)

18341 bidi_it->nchars is non-positive.
18342 (bidi_level_of_next_char): Don't try to lookup the cache for the
18343 next/previous character if nothing is cached there yet, or if we
18344 were just reseat()'ed to a new position.
18346 * xdisp.c (set_cursor_from_row): Set start and stop points
18347 according to the row's direction when priming the loop that looks
18348 for the glyph on which to display cursor.
18349 (single_display_spec_intangible_p): Function deleted.
18350 (display_prop_intangible_p): Reimplement to call
18351 handle_display_spec instead of single_display_spec_intangible_p.
18352 Accept 3 additional arguments needed by handle_display_spec.
18353 This fixes incorrect cursor motion across display property with complex
18354 values: lists, `(when COND...)' forms, etc.
18355 (single_display_spec_string_p): Support property values that are
18356 lists with the argument STRING its top-level element.
18357 (display_prop_string_p): Fix the condition for processing a
18358 property that is a list to be consistent with handle_display_spec.
18359 (handle_display_spec): New function, refactored from the
18360 last portion of handle_display_prop.
18361 (compute_display_string_pos): Accept additional argument
18362 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18363 value of a `display' property is a "replacing spec".
18364 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18365 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18366 the display property, but just return a value indicating whether
18367 the display property will replace the characters it covers.
18368 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18369 frame_window_p members of struct bidi_it.
18370 (compute_display_string_pos, compute_display_string_end):
18372 (push_it): Accept second argument POSITION, where pop_it should
18373 jump to continue iteration.
18374 (reseat_1): Initialize bidi_it.disp_pos.
18376 * keyboard.c (adjust_point_for_property): Adjust the call to
18377 display_prop_intangible_p to its new signature.
18379 * dispextern.h (struct bidi_it): New member frame_window_p.
18380 (bidi_init_it): Update prototypes.
18381 (display_prop_intangible_p): Update prototype.
18382 (compute_display_string_pos, compute_display_string_end):
18383 Declare prototypes.
18384 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18387 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18389 Malloc failure behavior now depends on size of allocation.
18390 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18391 * lisp.h: Change signatures accordingly.
18392 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18393 All callers changed. (Bug#8762)
18395 * gnutls.c: Use Emacs's memory allocators.
18396 Without this change, the gnutls library would invoke malloc etc.
18397 directly, which causes problems on non-SYNC_INPUT hosts, and which
18398 runs afoul of improving memory_full behavior. (Bug#8761)
18399 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18400 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18401 xfree instead of the default malloc, realloc, free.
18402 (Fgnutls_boot): No need to check for memory allocation failure,
18403 since xmalloc does that for us.
18405 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18406 * category.c (hash_get_category_set):
18407 * ccl.c (ccl_driver):
18408 * charset.c (Fdefine_charset_internal):
18409 * charset.h (struct charset.hash_index):
18410 * composite.c (get_composition_id, gstring_lookup_cache)
18411 (composition_gstring_put_cache):
18412 * composite.h (struct composition.hash_index):
18413 * dispextern.h (struct image.hash):
18414 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
18415 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
18416 (hashfn_equal, hashfn_user_defined, make_hash_table)
18417 (maybe_resize_hash_table, hash_lookup, hash_put)
18418 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18419 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18420 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18421 * image.c (make_image, search_image_cache, lookup_image)
18422 (xpm_put_color_table_h):
18423 * lisp.h (struct Lisp_Hash_Table):
18424 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18425 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18426 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18427 * alloc.c (allocate_vectorlike):
18428 Check for overflow in vector size calculations.
18429 * ccl.c (ccl_driver):
18430 Check for overflow when converting EMACS_INT to int.
18431 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18432 need to be updated by these changes.
18433 * fns.c (make_hash_table, maybe_resize_hash_table):
18434 Check for integer overflow with large hash tables.
18435 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18436 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18437 (SXHASH_REDUCE): New macro.
18438 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18439 Use it instead of discarding useful hash info with large hash values.
18440 (sxhash_float): New function.
18441 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18442 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18443 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18444 Rewrite to use FIXNUM_BITS, as this simplifies things.
18445 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18446 Adjust signatures to match updated version of code.
18447 (consing_since_gc): Now EMACS_INT, since a single hash table can
18448 use more than INT_MAX bytes.
18450 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18452 Make it possible to build with GCC-4.6+ -O2 -flto.
18454 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18456 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18458 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18459 Call minibuffer-inactive-mode.
18461 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18463 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18464 Update dependencies.
18466 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18468 * data.c (init_data): Remove code for UTS, this system is not
18471 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18473 Don't force ./temacs to start in terminal mode.
18475 * frame.c (make_initial_frame): Initialize faces in all cases, not
18476 only when CANNOT_DUMP is defined.
18477 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18479 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18481 * dispnew.c (add_window_display_history): Use const for the string
18482 pointer. Remove declaration, not needed.
18484 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18486 Use 'inline', not 'INLINE'.
18487 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18488 * alloc.c, fontset.c (INLINE): Remove.
18489 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18490 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18491 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18492 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18493 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18495 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18497 Make it possible to run ./temacs.
18499 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18500 syms_of_callproc does the same thing. Remove test for
18501 "initialized", do it in the caller.
18502 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18504 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18506 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18507 (read_minibuf): Use get_minibuffer.
18508 (syms_of_minibuf): Use DEFSYM.
18509 (Qmetadata): New var.
18510 * data.c (Qbuffer): Don't make it static.
18511 (syms_of_data): Use DEFSYM.
18513 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18515 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18516 (CCL_CODE_MIN): New macro.
18518 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18520 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18522 * eval.c (Qdebug): Now static.
18523 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18524 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18525 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18527 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18529 * image.c: Various fixes to ImageMagick code comments.
18530 (Fimagemagick_types): Doc fix.
18532 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18534 Minor fixes prompted by GCC 4.6.0 warnings.
18536 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18538 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18539 (x_clipboard_manager_save_all): Move extern decl to ...
18540 * xterm.h: ... here, so that it can be checked for consistency.
18542 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18544 * xselect.c (x_clipboard_manager_save_frame)
18545 (x_clipboard_manager_save_all): New functions.
18546 (Fx_clipboard_manager_save): Lisp function deleted.
18548 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18549 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18551 * xterm.h: Update prototype.
18553 2011-05-28 William Xu <william.xwl@gmail.com>
18555 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18556 exiting (Bug#8239).
18558 2011-05-28 Jim Meyering <meyering@redhat.com>
18560 Avoid a sign-extension bug in crypto_hash_function.
18561 * fns.c (to_uchar): Define.
18562 (crypto_hash_function): Use it to convert some newly-signed
18563 variables to unsigned, to avoid sign-extension bugs. For example,
18564 without this change, (md5 "truc") would evaluate to
18565 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18566 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18567 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18569 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18571 Integer overflow fixes.
18573 * dbusbind.c: Serial number integer overflow fixes.
18574 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18575 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18576 to hold a serial number that is too large for a fixnum.
18577 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18578 Check for serial numbers out of range. Decode any serial number
18579 that was so large that it became a float. (Bug#8722)
18581 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18582 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18583 Use XFASTINT rather than XUINT when numbers are nonnegative.
18584 (xd_append_arg, Fdbus_method_return_internal):
18585 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18586 arguments, check that Lisp number is nonnegative, rather than
18587 silently wrapping negative numbers around. (Bug#8722)
18588 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18591 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18593 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18595 ccl: Add integer overflow checks.
18596 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18597 (IN_INT_RANGE): New macros.
18598 (ccl_driver): Use them to check for integer overflow when
18599 decoding a CCL program. Many of the new checks are whether XINT (x)
18600 fits in int; it doesn't always, on 64-bit hosts. The new version
18601 doesn't catch all possible integer overflows, but it's an
18602 improvement. (Bug#8719)
18604 * alloc.c (make_event_array): Use XINT, not XUINT.
18605 There's no need for unsigned here.
18607 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18608 This follows up to the 2011-05-06 change that substituted uintptr_t
18609 for EMACS_INT. This case wasn't caught back then.
18611 Rework Fformat to avoid integer overflow issues.
18612 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18613 now (part of C89). Include <verify.h>.
18614 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18615 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18616 (Fformat): Avoid the prepass trying to compute sizes; it was only
18617 approximate and thus did not catch overflow reliably. Instead, walk
18618 through the format just once, formatting and computing sizes as we go,
18619 checking for integer overflow at every step, and allocating a larger
18620 buffer as needed. Keep track separately whether the format is
18621 multibyte. Keep only the most-recently calculated precision, rather
18622 than them all. Record whether each argument has been converted to
18623 string. Use EMACS_INT, not int, for byte and char and arg counts.
18624 Support field widths and precisions larger than INT_MAX. Avoid
18625 sprintf's undefined behavior with conversion specifications such as %#d
18626 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18627 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18628 formatting out-of-range floating point numbers with int
18629 formats. (Bug#8668)
18631 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18633 * data.c: Avoid integer truncation in expressions involving floats.
18634 * data.c: Include <intprops.h>.
18635 (arith_driver): When there's an integer overflow in an expression
18636 involving floating point, convert the integers to floating point
18637 so that the resulting value does not suffer from catastrophic
18638 integer truncation. For example, on a 64-bit host (* 4
18639 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18640 Do not rely on undefined behavior after integer overflow.
18642 merge count_size_as_multibyte, parse_str_to_multibyte
18643 * character.c, character.h (count_size_as_multibyte):
18644 Rename from parse_str_to_multibyte; all uses changed.
18645 Check for integer overflow.
18646 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18647 since it's now a duplicate of the other. This is more of
18648 a character than a buffer op, so better that it's in character.c.
18649 * fns.c, print.c: Adjust to above changes.
18651 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18653 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18655 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18657 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18658 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18659 (x_clipboard_manager_save): Now static.
18660 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18662 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18663 (crypto_hash_function): Now static.
18664 Fix pointer signedness problems. Avoid unnecessary initializations.
18666 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18668 * termhooks.h (Vselection_alist): Make it terminal-local.
18670 * terminal.c (create_terminal): Initialize it.
18672 * xselect.c: Support for clipboard managers.
18673 (Vselection_alist): Move to termhooks.h as terminal-local var.
18674 (LOCAL_SELECTION): New macro.
18675 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18676 (symbol_to_x_atom): Remove gratuitous arg.
18677 (x_handle_selection_request, lisp_data_to_selection_data)
18678 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18679 (x_own_selection, x_get_local_selection, x_convert_selection):
18680 New arg, specifying work frame. Use terminal-local Vselection_alist.
18681 (some_frame_on_display): Delete unused function.
18682 (Fx_own_selection_internal, Fx_get_selection_internal)
18683 (Fx_disown_selection_internal, Fx_selection_owner_p)
18684 (Fx_selection_exists_p): New optional frame arg.
18685 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18686 (x_handle_selection_clear): Don't treat other terminals with the
18687 same keyboard specially. Use the terminal-local Vselection_alist.
18688 (x_clear_frame_selections): Use Frun_hook_with_args.
18690 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18692 * xterm.h: Add support for those atoms.
18694 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18696 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18697 (converted_selections, conversion_fail_tag): New global variables.
18698 (x_selection_request_lisp_error): Free the above.
18699 (x_get_local_selection): Remove unnecessary code.
18700 (x_reply_selection_request): Args changed; handle arbitrary array
18701 of converted selections stored in converted_selections.
18702 Separate the XChangeProperty and SelectionNotify steps.
18703 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18704 (x_convert_selection): New function.
18705 (x_handle_selection_event): Simplify.
18706 (x_get_foreign_selection): Don't ignore incoming requests while
18707 waiting for an answer; this will fail when we implement
18708 SAVE_TARGETS, and seems unnecessary anyway.
18709 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18710 (Vx_sent_selection_functions): Doc fix.
18712 2011-05-26 Leo Liu <sdl.web@gmail.com>
18714 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18716 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18718 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18720 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18721 for fringe update if it has periodic bitmap.
18722 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18723 and fringe_bitmap_periodic_p.
18725 * fringe.c (get_fringe_bitmap_data): New function.
18726 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18727 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18728 row. Mark glyph row for fringe update if periodicity changed.
18730 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18731 for fringe update unless it has periodic bitmap.
18733 2011-05-25 Kenichi Handa <handa@m17n.org>
18735 * xdisp.c (get_next_display_element): Set correct it->face_id for
18736 a static composition.
18738 2011-05-24 Leo Liu <sdl.web@gmail.com>
18741 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18743 * fns.c (crypto_hash_function, Fsha1): New function.
18744 (Fmd5): Use crypto_hash_function.
18745 (syms_of_fns): Add Ssha1.
18747 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18749 * gnutls.c: Remove unused macros.
18750 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18751 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18752 Remove macros that are defined and never used.
18753 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18755 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18757 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18758 (Fx_get_selection_internal): Minor cleanup.
18759 (Fx_own_selection_internal): Rename arguments for consistency with
18762 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18764 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18766 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18768 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18770 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18772 * dispnew.c (scrolling_window): Don't exclude the case that the
18773 last enabled row in the desired matrix touches the bottom boundary.
18775 2011-05-21 Glenn Morris <rgm@gnu.org>
18777 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18778 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18779 and add some more files.
18781 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18783 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18784 report_file_error introduced by the change from 2011-05-07.
18786 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18788 * systime.h (Time): Define only if emacs is defined.
18789 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18790 where the include path doesn't have X11/X.h by default. See
18791 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18793 2011-05-20 Kenichi Handa <handa@m17n.org>
18795 * composite.c (find_automatic_composition): Fix previous change.
18797 2011-05-20 Glenn Morris <rgm@gnu.org>
18799 * lisp.mk: New file, split from Makefile.in.
18800 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18801 (shortlisp): Remove.
18802 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18804 2011-05-19 Glenn Morris <rgm@gnu.org>
18806 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18807 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18808 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18809 (lisp): Set the order to that of loadup.el.
18810 (shortlisp): Make it a copy of $lisp.
18811 (SOME_MACHINE_LISP): Remove.
18812 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18813 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18815 2011-05-18 Kenichi Handa <handa@m17n.org>
18817 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18818 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18819 (find_automatic_composition): Mostly rewrite for efficiency.
18821 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18823 * makefile.w32-in: Update dependencies.
18825 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18827 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18828 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18830 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18832 Fix some integer overflow issues, such as string length overflow.
18834 * insdel.c (count_size_as_multibyte): Check for string overflow.
18836 * character.c (lisp_string_width): Check for string overflow.
18837 Use EMACS_INT, not int, for string indexes and lengths; in
18838 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18839 the resulting string length overflows an EMACS_INT; instead,
18840 report a string overflow if no precision given. When checking for
18841 precision exhaustion, use a check that cannot possibly have
18842 integer overflow. (Bug#8675)
18843 * character.h (lisp_string_width): Adjust to new signature.
18845 * alloc.c (string_overflow): New function.
18846 (Fmake_string): Use it. This doesn't change behavior, but saves
18847 a few bytes and will simplify future changes.
18848 * character.c (string_escape_byte8): Likewise.
18849 * lisp.h (string_overflow): New decl.
18851 Fixups, following up to the user-interface timestamp change.
18852 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18853 for UI timestamps, instead of unsigned long.
18854 * msdos.c (mouse_get_pos): Likewise.
18855 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18856 * w32gui.h (Time): Define by including "systime.h" rather than by
18857 declaring it ourselves. (Bug#8664)
18859 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18860 * image.c (clear_image_cache): Likewise.
18862 * term.c (term_mouse_position): Don't assume time_t wraparound.
18864 Be more systematic about user-interface timestamps.
18865 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18866 and sometimes 'EMACS_UINT', to represent these timestamps.
18867 This change causes it to use 'Time' uniformly, as that's what X uses.
18868 This makes the code easier to follow, and makes it easier to catch
18869 integer overflow bugs such as Bug#8664.
18870 * frame.c (Fmouse_position, Fmouse_pixel_position):
18871 Use Time, not unsigned long, for user-interface timestamps.
18872 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18873 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18874 * keyboard.h (last_event_timestamp): Likewise.
18875 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18876 * menu.h (xmenu_show): Likewise.
18877 * term.c (term_mouse_position): Likewise.
18878 * termhooks.h (struct input_event.timestamp): Likewise.
18879 (struct terminal.mouse_position_hook): Likewise.
18880 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18881 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18882 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18883 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18884 what it was before.
18885 * menu.h, termhooks.h: Include "systime.h", for Time.
18887 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18888 Don't assume that the difference between two unsigned long values
18889 can fit into an integer. At this point, we know button_down_time
18890 <= event->timestamp, so the difference must be nonnegative, so
18891 there's no need to cast the result if double-click-time is
18892 nonnegative, as it should be; check that it's nonnegative, just in
18893 case. This bug is triggered when events are more than 2**31 ms
18894 apart (about 25 days). (Bug#8664)
18896 * xselect.c (last_event_timestamp): Remove duplicate decl.
18897 (x_own_selection): Remove needless cast to unsigned long.
18899 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18900 that always fit in int. Use a sentinel instead of a counter, to
18901 avoid a temp and to allay GCC's concerns about possible int overflow.
18902 * frame.h (struct frame): Use int for menu_bar_items_used
18903 instead of EMACS_INT, since it always fits in int.
18905 * menu.c (grow_menu_items): Check for int overflow.
18907 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18909 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18910 Before, the code was not consistent. These values cannot exceed
18911 2**31 - 1 so there's no need to make them unsigned.
18912 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18913 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18914 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18916 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18918 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18919 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18920 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18921 presumably because the widths might not match.
18923 * window.c (size_window): Avoid needless test at loop start.
18925 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18927 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18929 2011-05-12 Drew Adams <drew.adams@oracle.com>
18931 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18933 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18935 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18936 `width' to `bar_area_x' and `bar_area_width', respectively.
18937 (x_scroll_run): Take account of fringe background extension.
18939 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18940 Rename local vars `left' and `width' to `bar_area_x' and
18941 `bar_area_width', respectively.
18942 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18943 background extension.
18945 2011-05-10 Jim Meyering <meyering@redhat.com>
18947 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18949 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18951 * image.c (Finit_image_library): Return t for built-in image types,
18952 like pbm and xbm. (Bug#8640)
18954 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18956 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18958 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18960 * w32console.c (Fset_screen_color): Doc fix.
18961 (Fget_screen_color): New function.
18962 (syms_of_ntterm): Defsubr it.
18964 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18965 unlink the temporary file if Fcall_process didn't create it in the
18967 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18968 child process will be redirected to a file specified with `:file'.
18969 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18970 cue to call_process_cleanup not to close that handle.
18972 2011-05-07 Ben Key <bkey76@gmail.com>
18974 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18975 one of two shell specific rules, either bootstrap-temacs-CMD or
18976 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18977 to the previous implementation of the bootstrap-temacs rule.
18978 The bootstrap-temacs-CMD rule is similar to the previous
18979 implementation of the bootstrap-temacs rule except that it
18980 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18983 These changes, along with some changes to nt/configure.bat,
18984 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18985 earlier fix to add support for --cflags and --ldflags options
18986 that include quotes so that it works whether make uses cmd or
18989 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18991 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18992 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18994 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18995 a string. Handle both cases.
18996 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18997 (Fdbus_register_method): Use Qinvalid_function.
18999 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19001 * makefile.w32-in: Update dependencies.
19002 (LISP_H): Add inttypes.h and stdin.h.
19003 (PROCESS_H): Add unistd.h.
19005 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19007 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19008 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19010 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19012 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19014 * term.c (vfatal): Remove stray call to va_end.
19015 It's not needed and the C Standard doesn't allow it here anyway.
19017 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19018 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19020 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19023 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19025 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19027 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19029 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19031 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19033 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19034 * charset.c (Fdefine_charset_internal): Don't initialize
19035 charset.code_space[15]. The value was garbage, on hosts with
19036 32-bit int (Bug#8600).
19038 * lread.c (read_integer): Be more consistent with string-to-number.
19039 Use string_to_number to do the actual conversion; this avoids
19040 rounding errors and fixes some other screwups. Without this fix,
19041 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19042 (digit_to_number): Move earlier, for benefit of read_integer.
19043 Return -1 if the digit is out of range for the base, -2 if it is
19044 not a digit in any supported base. (Bug#8602)
19046 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19048 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19049 to match comment at start of function. This also removes a
19050 GCC warning about overflow in a 32+64-bit port.
19052 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19054 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19055 Reported by Stefan Monnier in
19056 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19057 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19058 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19060 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19061 (EMACS_UINTPTR): Likewise, with uintptr_t.
19063 * lisp.h: Prefer 64-bit EMACS_INT if available.
19064 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19065 on 32-bit hosts that have 64-bit int, so that they can access
19067 However, temporarily disable this change unless the temporary
19068 symbol WIDE_EMACS_INT is defined.
19070 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19072 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19073 This removes an assumption that EMACS_INT and long are the same
19074 width as pointers. The assumption is true for Emacs porting targets
19075 now, but we want to make other targets possible.
19076 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19077 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19078 In the rest of the code, change types of integers that hold casted
19079 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19080 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19081 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19082 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19083 No need to cast type when ORing.
19084 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19085 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19086 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19087 assume EMACS_INT is the same width as char *.
19088 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19089 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19090 Remove no-longer-needed casts.
19091 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19092 (xg_tool_bar_help_callback, xg_make_tool_item):
19093 Use EMACS_INTPTR to hold an integer
19094 that will be cast to void *; this can avoid a GCC warning
19095 if EMACS_INT is not the same width as void *.
19096 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19097 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19098 (current_message_1, set_message_1):
19099 Use a local to convert to proper width without a cast.
19100 * xmenu.c (dialog_selection_callback): Likewise.
19102 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19103 Also, don't assume VALBITS / RAND_BITS is less than 5,
19104 and don't rely on undefined behavior when shifting a 1 left into
19106 * lisp.h (get_random): Change signature to match.
19108 * lread.c (hash_string): Use size_t, not int, for hash computation.
19109 Normally we prefer signed values; but hashing is special, because
19110 it's better to use unsigned division on hash table sizes so that
19111 the remainder is nonnegative. Also, size_t is the natural width
19112 for hashing into memory. The previous code used 'int', which doesn't
19113 retain enough info to hash well into very large tables.
19114 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19116 * dbusbind.c: Don't possibly lose pointer info when converting.
19117 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19118 Use XPNTR rather than XHASH, so that the high-order bits of
19119 the pointer aren't lost when converting through void *.
19121 * eval.c (Fautoload): Don't double-shift a pointer.
19123 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

19132 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19135 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19137 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:

19157 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19158 Remove unused parameter `fildes'.
19159 * process.c (read_process_output, send_process): Don't pass it.
19161 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19163 Fix previous change: the library cache is defined in w32.c.
19164 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19165 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

19200 (w32_delayed_load): Move from image.c. When loading a library, record
19201 its filename in the :loaded-from property of the library id.

19203 Initialize and staticpro them.
19204 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19206 * process.c: Include lisp.h before w32.h, not after.
19207 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19208 instead of gnutls_record_check_pending.
19210 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19212 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19214 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19215 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19218 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19220 * xterm.c (x_set_frame_alpha): Do not set property on anything
19221 else than FRAME_X_OUTER_WINDOW (Bug#8608).

19225 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19227 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19229 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

19257 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19259 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19260 rather than `XVECTOR (FOO)->size'.
19262 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19263 inttypes.h, as a gnulib replacement is used if it not available in
19266 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19268 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19269 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19270 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19272 * coding.c (coding_alloc_by_realloc): Error out if destination
19273 will grow beyond MOST_POSITIVE_FIXNUM.
19274 (decode_coding_emacs_mule): Abort if there isn't enough place in
19275 charbuf for the composition carryover bytes. Reserve an extra
19276 space for up to 2 characters produced in a loop.

19278 charbuf for the composition carryover bytes.
19280 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19282 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19283 aborting when %lld or %lll format is passed.

19285 %llo or %llx format is passed. (Bug#8545)
19287 * window.c (window_scroll_line_based): Use a marker instead of
19288 simple variables to record original value of point. (Bug#7952)
19290 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19291 produced by %s or %c overflows available buffer space. (Bug#8545)
19293 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19295 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19298 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

19305 (command_loop_1): Run `delayed-warnings-hook'
19306 if Vdelayed_warnings_list is non-nil.
19307 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19308 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19310 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19312 * doprnt.c (doprnt): Don't return value smaller than the buffer
19313 size if the message was truncated. (Bug#8545).
19315 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19317 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

19324 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19326 * makefile.w32-in: Update dependencies.
19328 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19330 Improve `doprnt' and its usage. (Bug#8545)
19331 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19332 `format_end'. Remove support for %l as a conversion specifier.
19333 Don't use xrealloc. Improve diagnostics when the %l size modifier
19334 is used. Update the commentary.
19336 * eval.c (verror): Simplify calculation of size_t.
19338 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19341 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19343 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19346 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19348 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19349 This makes this file independent of the recent pseudovector change.
19351 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19353 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19355 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19356 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19357 Remove unused local.
19358 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19360 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19361 GCC 4.6.0 optimizes based on type-based alias analysis.
19362 For example, if b is of type struct buffer * and v of type struct
19363 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19364 != &v->size, and therefore "v->size = 1; b->size = 2; return
19365 v->size;" must therefore return 1. This assumption is incorrect
19366 for Emacs, since it type-puns struct Lisp_Vector * with many other
19367 types. To fix this problem, this patch adds a new type struct
19368 vectorlike_header that documents the constraints on layout of vectors
19369 and pseudovectors, and helps optimizing compilers not get fooled
19370 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19371 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19372 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19374 (XSETPVECTYPE): Rewrite in terms of new macro.
19375 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19376 This is a bit clearer, and further avoids the possibility of
19377 undesirable aliasing.
19378 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19379 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19380 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19381 since Lisp_Subr is a special case (no "next" field).
19382 (ASIZE): Now uses header.size rather than size.
19383 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19384 to avoid the hassle of writing XVECTOR (foo)->header.size.
19385 (struct vectorlike_header): New type.
19386 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19387 object, to help avoid aliasing.
19388 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19389 (SUBRP): Likewise, since Lisp_Subr is a special case.
19390 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19391 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19392 (struct Lisp_Hash_Table): Combine first two members into a single
19393 struct vectorlike_header member. All uses of "size" and "next" members
19394 changed to be "header.size" and "header.next".
19395 * buffer.h (struct buffer): Likewise.
19396 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19397 * frame.h (struct frame): Likewise.
19398 * process.h (struct Lisp_Process): Likewise.
19399 * termhooks.h (struct terminal): Likewise.
19400 * window.c (struct save_window_data, struct saved_window): Likewise.
19401 * window.h (struct window): Likewise.
19402 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19403 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19404 * buffer.c (init_buffer_once): Likewise.
19405 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19407 * process.c (Fformat_network_address): Use local var for size,
19410 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19412 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19413 * data.c (atof): Remove decl; no longer used or needed.
19414 (digit_to_number): Move to lread.c.
19415 (Fstring_to_number): Use new string_to_number function, to be
19416 consistent with how the Lisp reader treats infinities and NaNs.
19417 Do not assume that floating-point numbers represent EMACS_INT
19418 without losing information; this is not true on most 64-bit hosts.
19419 Avoid double-rounding errors, by insisting on integers when
19420 parsing non-base-10 numbers, as the documentation specifies.
19421 * lisp.h (string_to_number): New decl, replacing ...
19422 (isfloat_string): Remove.
19423 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19424 (read1): Do not accept +. and -. as integers; this
19425 appears to have been a coding error. Similarly, do not accept
19426 strings like +-1e0 as floating point numbers. Do not report
19427 overflow for integer overflows unless the base is not 10 which
19428 means we have no simple and reliable way to continue.
19429 Break out the floating-point parsing into a new
19430 function string_to_number, so that Fstring_to_number parses
19431 floating point numbers consistently with the Lisp reader.
19432 (digit_to_number): Move here from data.c. Make it static inline.
19433 (E_CHAR, EXP_INT): Remove, replacing with ...
19434 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19435 (string_to_number): New function, replacing isfloat_string.
19436 This function checks for valid syntax and produces the resulting
19437 Lisp float number too. Rework it so that string-to-number
19438 no longer mishandles examples like "1.0e+". Use strtoumax,
19439 so that overflow for non-base-10 numbers is reported only when
19440 there's no portable and simple way to convert to floating point.
19442 * textprop.c (set_text_properties_1): Rewrite for clarity,
19443 and to avoid GCC warning about integer overflow.
19445 * intervals.h (struct interval): Use EMACS_INT for members
19446 where EMACS_UINT might cause problems. See
19447 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19448 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19449 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19451 (offset_intervals): Tell GCC not to worry about length overflow
19452 when negating a negative length.
19454 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19455 (overrun_check_free): Likewise.
19457 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19458 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19461 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19462 (gnutls_make_error): Rename local to avoid shadowing.
19463 (gnutls_emacs_global_deinit): ifdef out; not used.
19464 (Fgnutls_boot): Use const for pointer to readonly storage.
19465 Comment out unused local. Fix pointer signedness problems.
19467 * lread.c (openp): Don't stuff size_t into an 'int'.
19468 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19469 about possible signed overflow.
19471 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19472 (GDK_KEY_g): Don't define if already defined.
19473 (xg_prepare_tooltip): Avoid pointer signedness problem.
19474 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19476 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19477 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19479 * xfns.c (Fx_window_property): Simplify a bit,
19480 to make a bit faster and to avoid GCC 4.6.0 warning.
19481 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19483 * fns.c (internal_equal): Don't assume size_t fits in int.
19485 * alloc.c (compact_small_strings): Tighten assertion a little.
19487 Replace pEd with more-general pI, and fix some printf arg casts.
19488 * lisp.h (pI): New macro, generalizing old pEd macro to other
19489 conversion specifiers. For example, use "...%"pI"d..." rather
19490 than "...%"pEd"...".
19491 (pEd): Remove. All uses replaced with similar uses of pI.
19492 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19493 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19494 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19495 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19496 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19497 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19498 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19500 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19501 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19502 * print.c (safe_debug_print, print_object): Likewise.
19503 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19505 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19506 avoiding the 0 flag, which is not portable.
19507 * process.c (Fmake_network_process): Use pI to avoid cast.
19508 * region-cache.c (pp_cache): Likewise.
19509 * xdisp.c (decode_mode_spec): Likewise.
19510 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19511 behavior on 64-bit hosts with printf arg.
19512 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19513 (x_stop_queuing_selection_requests): Likewise.
19514 (x_get_window_property): Don't truncate byte count to an 'int'
19517 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19518 here, since it parses constructs like leading '-' and spaces,
19519 which are not wanted; and it overflows with large numbers.
19520 Instead, simply match F[0-9]+, which is what is wanted anyway.

19526 plus offsetof, to remove unportable assumptions about struct layout.
19527 These assumptions hold on all porting targets that I know of, but
19528 they are not guaranteed, they're easy to remove, and removing them
19529 makes further changes easier.
19531 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19532 This doesn't fix a bug but makes the code clearer.
19533 (string_overrun_cookie): Now const. Use initializers that

19536 can cause Emacs to crash when string overrun checking is enabled.
19537 (allocate_buffer): Don't assume sizeof (struct buffer) is a

19576 supported by the function. Use SAFE_ALLOCA instead of always
19579 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19580 is one byte too soon. Don't use xrealloc; instead xfree and

19707 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19708 to `error' in error message about FINAL_CHAR argument. Make sure
19709 FINAL_CHAR is a character, and use %c when it is passed as
19710 argument to `error'.
19712 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19714 * s/ms-w32.h (localtime): Redirect to sys_localtime.
19716 * w32.c: Include <time.h>.

19900 ns_descriptor_to_entity that were caused by using free to
19901 deallocate memory blocks that were allocated by xmalloc (via

19922 (emacs_read, emacs_write): Use it.
19923 * process.c (send_process): Adjust to the new signatures of
19924 emacs_write and emacs_gnutls_write. Do not attempt to store

20412 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20413 argument, local variables, and return value.
20415 * lisp.h: Update prototypes of emacs_write and emacs_read.
20417 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20419 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20421 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20423 Fix more problems found by GCC 4.6.0's static checks.
20425 * xdisp.c (vmessage): Use a better test for character truncation.
20427 * charset.c (load_charset_map): <, not <=, for optimization,
20428 and to avoid potential problems with integer overflow.
20429 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20430 * casetab.c (set_identity, shuffle): Likewise.
20431 * editfns.c (Fformat): Likewise.
20432 * syntax.c (skip_chars): Likewise.
20434 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20435 This also lets GCC 4.6.0 generate slightly better loop code.
20437 * callint.c (Fcall_interactively): <, not <=, for optimization.
20438 (Fcall_interactively): Count the number of arguments produced,
20439 not the number of arguments given. This is simpler and lets GCC
20440 4.6.0 generate slightly better code.
20442 * ftfont.c: Distingish more carefully between FcChar8 and char.
20443 The previous code passed unsigned char * to a functions like
20444 strlen and xstrcasecmp that expect char *, which does not
20445 conform to the C standard.
20446 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20447 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20448 char * when the C standard requires it.
20450 * keyboard.c (read_char): Remove unused var.
20452 * eval.c: Port to Windows vsnprintf (Bug#8435).
20453 Include <limits.h>.
20454 (SIZE_MAX): Define if the headers do not.
20455 (verror): Do not give up if vsnprintf returns a negative count.
20456 Instead, grow the buffer. This ports to Windows vsnprintf, which
20457 does not conform to C99. Problem reported by Eli Zaretskii.
20458 Also, simplify the allocation scheme, by avoiding the need for
20459 calling realloc, and removing the ALLOCATED variable.
20461 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20463 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20464 But keep the doprint source code for now, as we might revamp it
20465 and use it again (Bug#8435).
20466 * lisp.h (doprnt): Remove.
20467 * Makefile.in (base_obj): Remove doprnt.o.
20468 * deps.mk (doprnt.o): Remove.
20470 error: Print 32- and 64-bit integers portably (Bug#8435).
20471 Without this change, on typical 64-bit hosts error ("...%d...", N)
20472 was used to print both 32- and 64-bit integers N, which relied on
20473 undefined behavior.
20474 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20475 * lisp.h (error, verror): Mark as printf-like functions.
20476 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20477 Report overflow in size calculations when allocating printf buffer.
20478 Do not truncate output string at its first null byte.
20479 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20480 Truncate the output at a character boundary, since vsnprintf does not
20482 * charset.c (check_iso_charset_parameter): Convert internal
20483 character to string before calling 'error', since %c now has the
20485 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20486 overflow when computing char to be passed to 'error'. Do not
20487 pass Lisp_Object to 'error'; pass the integer instead.
20488 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20489 formatted with plain %d.
20491 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20493 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20495 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20497 * xterm.c (x_catch_errors): Remove duplicate declaration.
20499 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20501 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20503 2011-04-10 Jim Meyering <meyering@redhat.com>
20505 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20506 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20507 return ssize_t not "int", and use size_t as the buffer length.
20508 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20509 * gnutls.h: Update declarations.
20510 * process.c (read_process_output): Use ssize_t, to match.
20511 (send_process): Likewise.
20513 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20515 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20517 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20519 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20520 Use unsigned char, to match FcChar8 type definition.
20522 * xterm.c (handle_one_xevent):
20523 * xmenu.c (create_and_show_popup_menu):
20524 * xselect.c (x_decline_selection_request)
20525 (x_reply_selection_request): Avoid type-punned deref of X events.
20527 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20529 Fix some uses of `int' instead of EMACS_INT.
20530 * search.c (string_match_1, fast_string_match)
20531 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20532 (scan_buffer, find_next_newline_no_quit)
20533 (find_before_next_newline, search_command, Freplace_match)
20534 (Fmatch_data): Make some `int' variables be EMACS_INT.
20536 * xdisp.c (display_count_lines): 3rd argument and return value now
20537 EMACS_INT. All callers changed.
20538 (pint2hrstr): Last argument is now EMACS_INT.
20540 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20541 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20542 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20543 (decode_coding_utf_16, decode_coding_emacs_mule)
20544 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20545 (decode_coding_ccl, decode_coding_charset)
20546 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20547 (decode_coding_iso_2022, decode_coding_emacs_mule)
20548 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20549 <char_offset, last_offset>: Declare EMACS_INT.
20550 (encode_coding_utf_8, encode_coding_utf_16)
20551 (encode_coding_emacs_mule, encode_invocation_designation)
20552 (encode_designation_at_bol, encode_coding_iso_2022)
20553 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20554 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20556 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20557 (encode_invocation_designation): Last argument P_NCHARS is now
20559 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20560 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20562 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20565 * ccl.c (Fccl_execute_on_string): Declare some variables
20568 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20570 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20572 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20574 * process.c (Fformat_network_address): Doc fix.
20576 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20578 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20580 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20582 * keyboard.c (read_char): Call Lisp function help-form-show,
20583 instead of using internal_with_output_to_temp_buffer.
20584 (Qhelp_form_show): New var.
20585 (syms_of_keyboard): Use DEFSYM macro.
20587 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20589 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20591 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20593 * process.c (Flist_processes): Remove to Lisp.
20594 (list_processes_1): Delete.

20600 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20602 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20604 Fix more problems found by GCC 4.6.0's static checks.

20608 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20610 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20612 * xdisp.c (vmessage): Mark as a printf-like function.
20614 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20616 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20618 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20619 printf-like functions.

20621 to system-supplied API.
20623 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20625 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20626 This avoids several warnings with gcc -Wstrict-overflow.
20627 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20628 directly, rather than having caller test rule sign. This avoids
20629 some unnecessary tests.
20630 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20631 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20632 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20634 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20635 (xfont_open): Avoid unnecessary tests.
20637 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20639 * composite.h, composite.c (composition_gstring_put_cache):
20640 Use EMACS_INT, not int, for length.

20643 breaking out part of COMPOSITION_DECODE_RULE.
20644 (COMPOSITION_DECODE_RULE): Use it.

20646 by using the new macro.
20648 * textprop.c (set_text_properties_1): Change while to do-while,
20649 since the condition is always true at first.
20651 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20652 (interval_deletion_adjustment): Return unsigned value.
20655 * process.c (list_processes_1, create_pty, read_process_output):

20667 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20668 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20669 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20671 * print.c (print_error_message): Avoid int overflow.
20673 * font.c (font_list_entities): Redo for clarity,
20674 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20676 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20677 (font_score): Avoid potential overflow in diff calculation.
20679 * fns.c (substring_both): Remove var that is set but not used.
20680 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20682 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20684 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20685 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20686 can always succeed if overflow has undefined behavior.
20688 * search.c (boyer_moore, wordify): Remove vars set but not used.
20689 (wordify): Omit three unnecessary tests.
20691 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20692 All callers changed. This avoids the need for an unused var.
20694 * casefiddle.c (casify_region): Remove var that is set but not used.
20696 * dired.c (file_name_completion): Remove var that is set but not used.

20706 * buffer.c (Fprevious_overlay_change): Remove var that is set
20709 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20710 Remove vars that are set but not used.
20711 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20712 (timer_check_2): Mark vars as initialized.
20714 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20716 * image.c (lookup_image): Remove var that is set but not used.
20717 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20719 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20720 that are set but not used.
20722 * xfns.c (make_invisible_cursor): Don't return garbage
20723 if XCreateBitmapFromData fails (Bug#8410).
20725 * xselect.c (x_get_local_selection, x_handle_property_notify):
20726 Remove vars that are set but not used.
20728 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

20738 (map_tty_color) [!defined MSDOS]: Likewise.
20740 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20742 * coding.c: Remove vars that are set but not used.
20743 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20744 All callers changed.

20746 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20747 (decode_coding_charset): Remove vars that are set but not used.
20749 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20750 that is set but not used.
20752 * print.c (print_object): Remove var that is set but not used.
20754 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20755 The gnulib version avoids calling malloc in the usual case,
20756 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20757 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20758 * filelock.c (current_lock_owner): Likewise.
20759 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

20764 ../lib/careadlinkat.h.
20766 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20768 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20769 first non-nil return value).

20783 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20784 and thereabouts. All callers changed.
20785 (get_per_char_metric): Remove parameter `f', unused since
20786 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20790 do not dereference NULL upon failed strdup
20791 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20792 (ns_get_family): Likewise.
20794 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

20847 * data.c (Finteractive_form): Handle closures.
20849 * callint.c (Fcall_interactively): Preserve lexical-binding mode for

20869 Limit scrolling to 100 screen lines.
20870 (redisplay_window): Even when falling back on "recentering",
20871 position point in the window according to scroll-conservatively,
20872 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20874 (try_scrolling): When point is above the window, allow searching
20875 as far as scroll_max, or one screenful, to compute vertical
20876 distance from PT to the scroll margin position. This prevents
20877 try_scrolling from unnecessarily failing when
20878 scroll-conservatively is set to a value slightly larger than the
20879 window height. Clean up the case of PT below the margin at bottom
20880 of window: scroll_max can no longer be INT_MAX. When aggressive
20881 scrolling is in use, don't let point enter the opposite scroll
20882 margin as result of the scroll.
20883 (syms_of_xdisp) <scroll-conservatively>: Document the
20884 threshold of 100 lines for never-recentering scrolling.
20886 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20888 * dispextern.h (move_it_by_lines):
20889 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20890 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20891 (message_log_check_duplicate): Remove parameters `prev_bol' and
20892 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20893 (redisplay_internal): Remove parameter `preserve_echo_area',
20894 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20896 * indent.c (Fvertical_motion):
20897 * window.c (window_scroll_pixel_based, Frecenter):
20898 Don't pass `need_y_p' to `move_it_by_lines'.
20900 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20902 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20903 steal a few bits to be more compact.
20904 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20905 Remove unneeded casts.
20907 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20909 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20911 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20912 binding" message (bug#7967).
20914 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20916 Fix more problems found by GCC 4.6.0's static checks.
20918 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20919 Remove unused local var.
20921 * editfns.c (Fmessage_box): Remove unused local var.
20923 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20924 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20925 Omit unused local vars.
20926 * window.c (shrink_windows): Omit unused local var.
20927 * menu.c (digest_single_submenu): Omit unused local var.
20928 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20929 Omit unused local var.
20931 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20932 Don't assume string length fits in int.
20933 (keyremap_step, read_key_sequence): Use size_t for sizes.
20934 (read_key_sequence): Don't check last_real_key_start redundantly.
20936 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20937 instead of alloca (Bug#8344).
20939 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20940 (Fbacktrace_frame): Don't assume nframes fits in int.
20942 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20944 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20947 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20949 * cm.c (calccost): Turn while-do into do-while, for clarity.
20951 * keyboard.c (syms_of_keyboard): Use the same style as later
20952 in this function when indexing through an array. This also
20953 works around GCC bug 48267.
20955 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20957 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20959 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20960 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20962 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20963 This avoids undefined behavior on integer overflow, and is a bit
20964 more convenient anyway since it is compared to a size_t variable.
20966 Variadic C functions now count arguments with size_t, not int.
20967 This avoids an unnecessary limitation on 64-bit machines, which
20968 caused (substring ...) to crash on large vectors (Bug#8344).
20969 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20970 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20971 All variadic functions and their callers changed accordingly.

20974 * editfns.c (general_insert_function): Likewise.
20975 * eval.c (struct backtrace.nargs, interactive_p)
20976 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20977 (funcall_lambda, mark_backtrace): Likewise.
20978 * fns.c (concat): Likewise.
20979 * frame.c (x_set_frame_parameters): Likewise.
20980 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20981 0 if not found, not -1. All callers changed.
20983 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20984 (stack_copy_size): Now size_t, not int.
20985 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20987 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20989 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20990 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20991 All callers changed.
20993 * lisp.h (multibyte_char_to_unibyte):
20994 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20995 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20996 * character.h (CHAR_TO_BYTE8):
20997 * cmds.c (internal_self_insert):
20998 * editfns.c (general_insert_function):
20999 * keymap.c (push_key_description):
21000 * search.c (Freplace_match):
21001 * xdisp.c (message_dolog, set_message_1): All callers changed.
21003 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21005 * keyboard.c (safe_run_hook_funcall): New function.
21006 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21007 don't set the hook to nil, but remove the offending function instead.
21008 (Qcommand_hook_internal): Remove, unused.
21009 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21010 Vcommand_hook_internal.
21012 * eval.c (enum run_hooks_condition): Remove.
21013 (funcall_nil, funcall_not): New functions.
21014 (run_hook_with_args): Call each function through a `funcall' argument.
21015 Remove `cond' argument, now redundant.
21016 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21017 (Frun_hook_with_args_until_failure): Adjust accordingly.
21018 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21020 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21022 * dispextern.h (string_buffer_position): Remove declaration.
21024 * print.c (strout): Remove parameter `multibyte', unused since
21025 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21027 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21028 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21029 All callers changed.
21031 * w32.c (_wsa_errlist): Use braces for struct initializers.
21033 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21034 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21035 All callers changed.
21036 (string_buffer_position): Likewise. Also, make static (it's never
21037 used outside xdisp.c).
21038 (cursor_row_p): Remove parameter `w', unused since
21039 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21041 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21042 All callers changed.
21044 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21046 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21051 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
21052 (ns_update_auto_hide_menu_bar): New functions.
21053 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

21057 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21059 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21061 * nsmenu.m (runDialogAt): Remove argument to timer_check.
21063 2011-03-27 Glenn Morris <rgm@gnu.org>
21065 * syssignal.h: Replace RETSIGTYPE with void.
21066 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
21067 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
21068 Replace SIGTYPE with void everywhere.
21069 * s/usg5-4-common.h (SIGTYPE): Remove definition.

21072 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21074 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21075 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21077 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21079 * w32.c (read_unc_volume): Use parameter `henum', instead of
21080 global variable `wget_enum_handle'.
21082 * keymap.c (describe_vector): Remove parameters `indices' and
21083 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21086 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21088 * keyboard.c (timer_check): Remove parameter `do_it_now',
21089 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
21090 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
21091 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.

21094 * w32menu.c (w32_menu_display_help):
21095 * xmenu.c (show_help_event, menu_help_callback):
21096 Adjust calls to `show_help_echo'.
21098 * gtkutil.c (xg_maybe_add_timer):
21099 * keyboard.c (readable_events):
21100 * process.c (wait_reading_process_output):
21101 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21103 * insdel.c (adjust_markers_gap_motion):
21104 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

21153 * w32term.c (x_set_glyph_string_clipping):
21154 Don't pass uninitialized region to CombineRgn.
21156 2011-03-23 Juanma Barranquero <lekktu@gmail.com>

21178 2011-03-23 Julien Danjou <julien@danjou.info>
21180 * term.c (Fsuspend_tty, Fresume_tty):
21181 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21182 * window.c (temp_output_buffer_show):
21183 * insdel.c (signal_before_change):
21184 * frame.c (Fhandle_switch_frame):
21185 * fileio.c (Fdo_auto_save):
21186 * emacs.c (Fkill_emacs):
21187 * editfns.c (save_excursion_restore):
21188 * cmds.c (internal_self_insert):
21189 * callint.c (Fcall_interactively):
21190 * buffer.c (Fkill_all_local_variables):
21191 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21193 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21194 unconditionally since it does the check itself.
21196 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21198 Fix more problems found by GCC 4.5.2's static checks.
21200 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21201 the first time through the loop, since we know p0 < p1 then.
21202 This also avoids a gcc -Wstrict-overflow warning.
21204 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21205 leading to a memory leak, possible in functions like
21206 load_charset_map_from_file that can allocate an unbounded number
21207 of objects (Bug#8318).
21209 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21210 that could (at least in theory) be that large.
21212 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21213 This is less likely to overflow, and avoids undefined behavior if
21214 overflow does occur. All callers changed. Use strtoul to scan
21215 for the unsigned long integer.
21216 (pint2hrstr): Simplify and tune code slightly.
21217 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21219 * scroll.c (do_scrolling): Work around GCC bug 48228.
21220 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21222 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21223 This also avoids a warning with gcc -Wstrict-overflow.

21225 This also avoids a warning with gcc -Wstrict-overflow.
21227 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21230 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21232 * process.c (Fmake_network_process): Use socklen_t, not int,
21233 where POSIX says socklen_t is required in portable programs.
21234 This fixes a porting bug on hosts like 64-bit HP-UX, where
21235 socklen_t is wider than int (Bug#8277).
21236 (Fmake_network_process, server_accept_connection):
21237 (wait_reading_process_output, read_process_output):
21240 * process.c: Rename or move locals to avoid shadowing.
21241 (list_processes_1, Fmake_network_process):
21242 (read_process_output_error_handler, exec_sentinel_error_handler):
21243 Rename or move locals.
21244 (Fmake_network_process): Define label "retry_connect" only if needed.
21245 (Fnetwork_interface_info): Fix pointer signedness.
21246 (process_send_signal): Add cast to avoid pointer signedness problem.
21247 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21248 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21250 Make tparam.h and terminfo.c consistent.
21251 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21252 Include tparam.h instead, since it declares them.
21253 * cm.h (PC): Remove extern decl; tparam.h now does this.
21254 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21255 * terminfo.c: Include tparam.h, to check interfaces.
21256 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21257 (tparam): Adjust signature to match interface in tparam.h;
21258 this removes some undefined behavior. Check that outstring and len
21259 are zero, which they always are with Emacs.
21260 * tparam.h (PC, BC, UP): New extern decls.
21262 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21263 (xftfont_open): Rename locals to avoid shadowing.
21265 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21266 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21267 (OTF_TAG_SYM): Omit macro if not needed.
21268 (ftfont_list): Remove unused local.
21269 (get_adstyle_property, ftfont_pattern_entity):
21270 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21271 Rename locals to avoid shadowing.
21273 * xfont.c (xfont_list_family): Mark var as initialized.
21275 * xml.c (make_dom): Now static.
21277 * composite.c (composition_compute_stop_pos): Rename local to
21279 (composition_reseat_it): Remove unused locals.
21280 (find_automatic_composition, composition_adjust_point): Likewise.
21281 (composition_update_it): Mark var as initialized.
21282 (find_automatic_composition): Mark vars as initialized,
21283 with a FIXME (Bug#8290).
21285 character.h: Rename locals to avoid shadowing.
21286 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21287 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21288 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21289 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21290 to avoid shadowing.
21292 * textprop.c (property_change_between_p): Remove; unused.
21294 * intervals.c (interval_start_pos): Now static.
21296 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
21298 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
21299 Rename locals to avoid shadowing.
21301 * sound.c (wav_play, au_play, Fplay_sound_internal):
21302 Fix pointer signedness.
21303 (alsa_choose_format): Remove unused local var.

21312 clobbering (Bug#8298).
21313 * sysdep.c (sys_subshell): Likewise.
21314 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21316 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21317 This should get cleaned up, so that child_setup has the
21318 same signature on all platforms.
21320 * callproc.c (call_process_cleanup): Now static.
21321 (relocate_fd): Rename locals to avoid shadowing.
21323 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

21451 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21452 some of which prompt warnings from gcc -Wbad-function-cast.
21453 (Fformat_time_string, Fencode_time, Finsert_char):

21482 (Fmemory_limit): Cast sbrk's returned value to char *.
21484 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21487 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21489 Use functions, not macros, for up- and down-casing (Bug#8254).
21490 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21491 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21492 to use the following functions instead of these macros.
21493 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21494 EMACS_INT, since callers assume the returned value fits in int.
21495 (upcase1): Likewise, for UPCASE_TABLE.
21496 (uppercasep, lowercasep, upcase): New static inline functions.
21497 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21507 (regex_compile, re_match_2_internal): Mark locals as initialized.
21508 (RETALLOC_IF): Define only if needed.
21509 (WORDCHAR_P): Likewise. This one is never needed, but is used
21510 only in a comment talking about a compiler bug, so put inside
21511 the #if 0 of that comment.
21512 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21513 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21539 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21540 New macros, so that the caller can use some names other than
21541 gcpro1, gcpro2, etc.
21542 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21544 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21545 argument, for consistency with GCPRO2_VAR, etc: it is now the
21546 prefix of the variable, not the variable itself. All uses
21548 * dired.c (directory_files_internal, file_name_completion):
21549 Rename locals to avoid shadowing.
21551 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21552 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21553 dired.c's scmp function, had undefined behavior.
21554 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21555 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21556 * buffer.h: ... to here, because these macros use current_buffer,
21557 and the new implementation with inline functions needs to have
21558 current_buffer in scope now, rather than later when the macros
21560 (downcase, upcase1): New static inline functions.
21561 (DOWNCASE, UPCASE1): Reimplement using these functions.
21562 This avoids undefined behavior in expressions like
21563 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21564 from race conditions in accessing the global variables
21565 case_temp1 and case_temp2.
21566 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21567 * lisp.h (case_temp1, case_temp2): Remove their decls.
21568 * character.h (ASCII_CHAR_P): Move from here ...
21569 * lisp.h: ... to here, so that the inline functions mentioned
21570 above can use them.
21572 * dired.c (directory_files_internal_unwind): Now static.
21574 * fileio.c (file_name_as_directory, directory_file_name):

21577 (file_name_as_directory): Use const pointers when appropriate.
21578 (Fexpand_file_name): Likewise. In particular, newdir might
21579 point at constant storage, so make it a const pointer.
21580 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21581 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21583 (Fset_file_times, Finsert_file_contents, auto_save_error):

21588 to avoid shadowing.
21590 * marker.c (bytepos_to_charpos): Remove; unused.
21592 * lisp.h (verify_bytepos, count_markers): New decls,
21593 so that gcc does not warn that these functions aren't declared.
21595 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21596 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21597 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21598 (copy_text): Remove unused local var.
21600 * filelock.c (within_one_second): Now static.
21601 (lock_file_1): Rename local to avoid shadowing.
21603 * buffer.c (fix_overlays_before): Mark locals as initialized.
21604 (fix_start_end_in_overlays): Likewise. This function should be
21605 simplified by using pointers-to-pointers, but that's a different
21607 (switch_to_buffer_1): Now static.
21608 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21609 (report_overlay_modification): Rename locals to avoid shadowing.
21611 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21612 Fix pointer signedness issue.
21613 (sys_subshell): Mark local as volatile if checking for lint,
21614 to suppress a gcc -Wclobbered warning that does not seem to be right.
21615 (MAXPATHLEN): Define only if needed.
21617 * process.c (serial_open, serial_configure): Move decls from here ...
21618 * systty.h: ... to here, so that they can be checked.
21620 * fns.c (get_random, seed_random): Move extern decls from here ...
21621 * lisp.h: ... to here, so that they can be checked.
21623 * sysdep.c (reset_io): Now static.
21624 (wait_for_termination_signal): Remove; unused.
21626 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
21627 (copy_keymap_item, append_key, push_text_char_description):
21629 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21630 (DENSE_TABLE_SIZE): Remove; unused.
21631 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21632 (describe_map_tree):
21633 Rename locals to avoid shadowing.
21635 * keyboard.c: Declare functions static if they are not used elsewhere.
