9 (load_each_byte): Remove. Update users.
11 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
13 * search.c (scan_buffer): Calculate end byte position just once.

15 (search_command): Use eassert.
16 * syntax.c (struct lisp_parse_state): New member location_byte.
17 (scan_sexps_forward): Record from_byte and avoid redundant
18 character to byte position calculation ...
19 (Fparse_partial_sexp): ... here. Break too long line.
21 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
23 * lisp.h (make_uninit_vector): New function.
24 * alloc.c (Fvector, Fmake_byte_code):
25 * ccl.c (Fregister_ccl_program):
26 * charset.c (Fdefine_charset_internal, define_charset_internal):
27 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
28 * composite.c (syms_of_composite):

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

78 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
79 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
80 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
81 (syms_of_nsterm): Add ns-use-native-fullscreen.
83 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
85 * fileio.c (Qchoose_write_coding_system): Now static.
87 2013-02-04 Eli Zaretskii <eliz@gnu.org>
89 * xdisp.c (window_buffer_changed): region_showing can be negative,
90 which still means region is being displayed.
91 (redisplay_internal): Resurrect code that forced redisplay of the
92 whole window when showing region and the mark has changed. Record
93 the new mark position to allow redisplay optimizations.
94 (display_line): If it->region_beg_charpos is non-zero, set the
95 window's region_showing member to -1. (Bug#13623) (Bug#13626)
97 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
98 not bitfield of 1 bit.
100 2013-02-03 Daniel Colascione <dancol@dancol.org>
102 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
103 daemon mode works on cygw32 when Emacs is installed and not just
106 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
108 Avoid file time stamp bug on MS-Windows (Bug#13149).
109 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
110 as FAT32 doesn't update time stamps when truncating them.
111 Also, check that a file time stamp is not a multiple of 100 ns;
112 this should catch all instances of the problem on MS-Windows,
113 as its native file system resolution is 100 ns or worse, and
114 checking for a non-multiple of 100 ns should impose only a small
115 overhead on systems with ns resolution.
117 2013-02-02 Eli Zaretskii <eliz@gnu.org>
119 Avoid encoding file names on MS-Windows when they need to be run
120 through dostounix_filename.
121 * w32.c (normalize_filename): Accept an additional argument
122 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
123 downcase it even if w32-downcase-file-names is non-nil.
124 (dostounix_filename): Accept an additional argument MULTIBYTE and
125 pass it to normalize_filename.
126 (emacs_root_dir): Adjust.
128 * msdos.h (dostounix_filename): Adjust prototype.
130 * w32.h (dostounix_filename): Adjust prototype.
132 * msdos.c (dostounix_filename): Accept an additional argument and
134 (init_environment): Adjust callers of dostounix_filename.
136 * fileio.c (Ffile_name_directory, file_name_as_directory)
137 (directory_file_name, Fexpand_file_name)
138 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
140 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
142 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
143 variables, as egetenv is case-insensitive for DOS_NT.
145 * dired.c (file_name_completion): Don't call Fdirectory_file_name
146 with an encoded file name.
148 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
149 calls to dostounix_filename.
151 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
153 * unexw32.c (unexec): Adjust call to dostounix_filename.
155 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
157 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
160 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
163 * callproc.c (Fcall_process): Make sure program name in PATH and
164 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
165 is passed to exec/spawnve, which fails unless the file-name
168 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
169 even if w32-quote-process-args is nil.
171 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
173 Fix timestamp bug when write-region appends nothing (Bug#13149).
174 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
175 the file's time stamp doesn't change if Emacs happens to write nothing
176 to the file, and on a buggy file system this could cause Emacs to
177 incorrectly infer that the file system doesn't have the bug.
178 Avoid this problem by inhibiting the inference in this case.
180 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
182 * window.h (struct window): Convert base_line_number, base_line_pos
183 and column_number_displayed members from Lisp_Object to ptrdiff_t.
184 Convert region_showing member from Lisp_Object to bitfield.
185 Remove sequence_number member. Adjust comments.
186 * window.c (sequence_number): Remove.
187 (make_window): Initialize column_number_displayed.
188 * print.c (print_object): Follow the printed representation of
189 frames and print window pointer to distinguish between windows.
190 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
191 * xdisp.c (wset_base_line_number, wset_base_line_pos)
192 (wset_column_number_displayed, wset_region_showing): Remove.
193 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
194 (try_scrolling, try_cursor_movement, redisplay_window)
195 (try_window_reusing_current_matrix, try_window_id, display_line)
196 (display_mode_lines, decode_mode_spec): Adjust users.
197 * .gdbinit (pwinx): Do not print sequence_number.
199 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
201 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
202 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
203 * dired.c: Include <fcntl.h>.
204 (open_directory): New function, which uses open and fdopendir
205 rather than opendir. DOS_NT platforms still use opendir, though.
206 (directory_files_internal, file_name_completion): Use it.
207 (file_attributes): New function, with most of the old Ffile_attributes.
208 (directory_files_internal, Ffile_attributes): Use it.
209 (file_attributes, file_name_completion_stat): First arg is now fd,
210 not dir name. All uses changed. Use fstatat rather than lstat +
212 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
213 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
214 (emacs_readlinkat): New function, with much of the old
215 Ffile_symlink_p, but with an fd argument for speed.
216 It uses readlinkat rather than careadlinkatcwd, so that it
217 need not assume the working directory.
218 (Ffile_symlink_p): Use it.
219 * filelock.c (current_lock_owner): Use emacs_readlinkat
220 rather than emacs_readlink.
221 * lisp.h (emacs_readlinkat): New decl.
222 (READLINK_BUFSIZE, emacs_readlink): Remove.
223 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
224 (emacs_norealloc_allocator, emacs_readlink): Remove.
225 This stuff is moved to fileio.c.
226 * w32.c (fstatat, readlinkat): New functions.
227 (careadlinkat): Don't check that fd == AT_FDCWD.
228 (careadlinkatcwd): Remove; no longer needed.
230 2013-01-31 Glenn Morris <rgm@gnu.org>
232 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
233 (Fwrite_region): Update for new choose_write_coding_system args.
234 Move the last piece of choose_write_coding_system here. (Bug#13522)
235 (syms_of_fileio): Add choose-write-coding-system.
237 2013-01-30 Eli Zaretskii <eliz@gnu.org>
239 * w32.c (sys_open): Zero out the flags for the new file descriptor.
240 (sys_close): Zero out the flags for the file descriptor before
241 closing it. (Bug#13546)
243 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
244 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
245 CharNextExA and CharPrevExA to iterate over file names encoded in
248 * w32.c (w32_get_long_filename, init_environment, readlink):
249 Support file names encoded in DBCS codepages.
250 (readlink): Use the current file-name-coding-system, not the ANSI
251 codepage, to decode and handle targets of symlinks.
253 2013-01-28 Eli Zaretskii <eliz@gnu.org>
255 * w32.c (opendir): Now accepts a 'const char *'.
257 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
259 Remove obsolete redisplay code. See the discussion at
260 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
261 * dispnew.c (preemption_period, preemption_next_check): Remove.
262 (Vredisplay_preemption_period): Likewise.
263 (update_frame, update_single_window, update_window, update_frame_1):
264 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
265 used, following the 2012-06-22 change.
267 2013-01-25 Eli Zaretskii <eliz@gnu.org>
269 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
271 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
273 * font.c (num_fonts): Remove the leftover from old
274 debugging code. Adjust comment style here and there.
275 * insdel.c (insert_1): Remove.
276 * lisp.h (insert_1): Remove prototype.
277 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
279 2013-01-25 Eli Zaretskii <eliz@gnu.org>
281 * w32.c (max_filename_mbslen): New function.
282 (normalize_filename, readdir): Use it to detect locales where ANSI
283 encoding of file names uses a double-byte character set (DBCS).
284 If a DBCS encoding is used, advance by characters using
285 CharNextExA, instead of incrementing a 'char *' pointer. Use
286 _mbslwr instead of _strlwr. (Bug#13515)
288 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
289 request of memory reservation to 1.7GB. (Bug#13065)
291 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
293 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
294 at check_extra_latin label. (Bug#13505)
296 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
298 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
299 Avoid redundant calls to strlen.
301 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
303 Drop async_visible and async_iconified fields of struct frame.
304 This is possible because async input is gone; for details, see
305 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
306 * frame.h (struct frame): Remove async_visible and async_iconified
307 members, convert garbaged to unsigned bitfield. Adjust comments.
308 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
309 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
310 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
311 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
312 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
314 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
315 properly. Likewise for obscured.
317 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
320 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
322 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
324 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
325 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
327 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
329 * xdisp.c (message2, message2_nolog): Remove functions.
330 (message3, message3_nolog): Extract nbytes and multibyteness directly
331 from the string. Change all callers.
332 (message3_nolog): Don't set message_enable_multibyte since set_message
333 will reset it anyway.
334 (message1, message1_nolog): Use message3.
335 (vmessage): Use a stack allocated buffer rather than f->message_buf.
336 (with_echo_area_buffer): Remove last two arguments. Update all callers.
337 (set_message): Drop all but the second arg, which has to be a string.
338 (set_message_1): Simplify now that we know that a1 is NULL and the
339 second arg is a string.
340 * frame.h (struct frame): Remove `message_buf' field.
341 Use glyphs_initialized_p instead.
342 (FRAME_MESSAGE_BUF): Remove macro.
343 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
344 * lisp.h (message2, message2_nolog): Remove declarations.
345 (message3, message3_nolog): Update declarations.
346 * keyboard.c (read_char_minibuf_menu_text)
347 (read_char_minibuf_menu_width): Remove vars.
348 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
349 to correctly handle multibyte strings.
350 * frame.c (delete_frame): Don't free message_buf any more.
351 * editfns.c (message_text, message_length): Remove vars.
352 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
353 * fileio.c (auto_save_error): Use message3 instead of message2.
354 * dispnew.c (adjust_frame_message_buffer): Remove function.
356 2013-01-23 Eli Zaretskii <eliz@gnu.org>
358 * w32term.c (w32fullscreen_hook): Account correctly for the screen
359 real estate used for the tool bar and the menu bar.
361 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
363 * insdel.c (prepare_to_modify_buffer): Force redisplay if
364 hidden buffer is prepared to modification (Bug#13164).
366 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
368 * window.h (struct window): Change window_end_valid member from
369 Lisp_Object to a bitfield. Adjust comments.
370 (wset_window_end_valid): Remove.
371 * window.c (adjust_window_count): Clear window_end_valid.
372 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
373 (Fwindow_line_height, set_window_buffer, Frecenter)
374 (Fsplit_window_internal, Fdelete_other_windows_internal)
375 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
376 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
377 * xdisp.c (check_window_end, reconsider_clip_changes)
378 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
379 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
380 (find_first_unchanged_at_end_row, try_window_id): Likewise.
382 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
384 * xdisp.c (mark_window_display_accurate): Simplify the loop
385 assuming that the only one of vchild, hchild or buffer window
386 slots is non-nil. Call mark_window_display_accurate_1 for
387 the leaf windows only.
388 (mark_window_display_accurate_1): Always assume leaf window.
391 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
393 * emacs.c (Qkill_emacs_hook): Now static.
395 * fileio.c (Finsert_file_contents): Simplify.
396 Remove unnecessary assignments and tests.
398 2013-01-21 Eli Zaretskii <eliz@gnu.org>
400 * w32.c (acl_set_file): Don't test for errors unless
401 set_file_security returns FALSE. Avoids spurious errors when
404 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
406 * fileio.c (Finsert_file_contents): Revert code introduced at
407 2013-01-18 in favor of the simpler and generally better fix.
408 Save stack space by removing 'buffer' and reusing 'read_buf'
411 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
413 * lisp.h (eabs): Define unconditionally (Bug#13419).
414 The old "#if !defined (eabs)" was an unnecessary revenant of back
415 when this macro was called "abs". Document 'eabs' better.
417 2013-01-19 Glenn Morris <rgm@gnu.org>
419 * fns.c (Frandom): Doc fix.
421 2013-01-19 Eli Zaretskii <eliz@gnu.org>
423 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
424 segfault when there are lots of overlays.
426 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
427 when there are lots of overlays. See
428 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
429 for the details and a way to reproduce.
431 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
433 * fileio.c: Use O_APPEND to append.
434 This corresponds better to the natural interpretation of "append",
435 and avoids the need to open the output file twice, or to invoke
436 lseek when APPEND is neither nil nor a number.
437 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
438 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
439 file possibly twice, and lseeking to its end; this avoids the
440 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
441 at the same time: the combination is never needed and apparently
442 it doesn't work with DOS_NT.
444 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
445 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
447 Allow floating-point file offsets.
448 Problem reported by Vitalie Spinu in
449 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
450 * fileio.c (emacs_lseek): Remove.
451 (file_offset): New function.
452 (Finsert_file_contents, Fwrite_region): Use it.
454 2013-01-19 Chong Yidong <cyd@gnu.org>
456 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
457 aborting on Fsignal (Bug#13289).
459 2013-01-19 Eli Zaretskii <eliz@gnu.org>
461 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
462 set_file_security as failure due to insufficient privileges.
463 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
464 (fstat): Return owner and group like 'stat' and 'lstat' do.
466 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
468 Work around bug in CIFS and vboxsf file systems (Bug#13149).
469 The bug was observed on Ubuntu operating inside a virtual machine,
470 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
471 The workaround introduces a race condition on non-buggy hosts,
472 but it's an unlikely race and anyway there's a nearly identical
473 nearby race that can't be fixed.

956 * w32.c (acl_set_file): If setting the file security descriptor
957 fails, and the new DACL is identical to the existing one, silently
958 return success. This fixes problems for users backing up their
959 own files without having the necessary privileges for setting
960 security descriptors.
962 * w32proc.c (reader_thread): Do not index fd_info[] with negative
964 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
965 after WaitForSingleObject returns normally. This expedites reader
966 thread shutdown when delete_child triggers it.
967 (reap_subprocess): More accurate commentary for why we call
968 delete_child only when cp->fd is negative.
970 * w32.c (sys_close): Do not call delete_child on a subprocess
971 whose handle is not yet closed. Instead, set its file descriptor
972 to a negative value, so that reap_subprocess will call
973 delete_child on that subprocess when its SIGCHLD arrives.
974 This avoids closing handles used for communications between sys_select
975 and reader_thread, which doesn't give sys_select a chance to
976 notice that the process exited and invoke the SIGCHLD handler for
979 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
981 * nsfns.m (Fns_do_applescript): Run event loop until script has
982 been executed (Bug#12969).
983 (ns_run_ascript): Chech as_script for nil, set to nil after
986 2012-12-22 Martin Rudalics <rudalics@gmx.at>
988 * window.c (Fselect_window): Reword doc-string (Bug#13248).
990 2012-12-22 Eli Zaretskii <eliz@gnu.org>
992 * w32term.c (w32fullscreen_hook): New function.
993 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
995 2012-12-21 Eli Zaretskii <eliz@gnu.org>
997 * fileio.c (Finsert_file_contents): Doc fix.
999 * w32proc.c (new_child, delete_child, find_child_pid): For a
1000 subprocess, consider its slot being in use as long as its process
1001 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1002 slot when a new process is started immediately after killing
1003 another one, without waiting enough time for the first process to
1004 be reaped and resources allocated for it be orderly freed.
1006 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1008 2012-12-21 Chong Yidong <cyd@gnu.org>
1010 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1012 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1014 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1016 * w32.c (get_name_and_id): Always pass NULL as the first argument
1017 of lookup_account_sid. Avoids crashes with UNC file names that
1018 refer to DFS domains, not to specific machine names. (Bug#12621)
1019 Remove now unused argument FNAME; all callers changed.
1020 (get_file_owner_and_group): Remove now unused argument FNAME; all
1023 2012-12-21 Chong Yidong <cyd@gnu.org>
1025 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1026 error for invalid chars, don't check for a nil return value.
1028 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1030 Avoid calls to CHAR_TO_BYTE if byte position is known.
1031 * editfns.c (make_buffer_string_both): Use move_gap_both.
1032 (Fbuffer_string): Use make_buffer_string_both.
1033 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1035 (buf_bytepos_to_charpos): Likewise.
1036 (charpos_to_bytepos): Remove.
1037 * fileio.c (Finsert_file_contents): Use move_gap_both.
1038 * search.c (Freplace_match): Likewise.
1039 * process.c (process_send_region): Likewise. Use convenient
1040 names for byte positions.
1041 * lisp.h (charpos_to_bytepos): Remove prototype.
1042 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1043 * insdel.c (move_gap): Likewise.

1049 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1051 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1052 (redisplay_internal): Don't bother selecting the frame to get the
1053 proper value of frame-local variables (bug#13225).
1055 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1057 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1058 Rename 4th argument since it may be buffer or string. Adjust comment.
1059 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1061 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1063 * coding.c (Fdetect_coding_region): Do not check start and end with
1064 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1065 (code_convert_region): Likewise.
1067 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1069 * w32.c (acl_get_file, acl_set_file): Run the file name through
1070 map_w32_filename, and resolve any symlinks in the file name, like
1072 (acl_set_file): Call revert_to_self, if any privileges were

1078 ($(BLD)/w32.$(O)): Update dependencies.
1080 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1082 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1083 propagate redisplay's scrolling (if any) to the right window.
1084 (redisplay_internal): Use ensure_selected_frame.
1085 (display_mode_lines): Complete last fix.
1086 * window.c (select_window_1): New func, extracted from select_window.
1087 (select_window): Use it.
1088 * window.h (select_window_1): Declare.
1090 2012-12-17 Eli Zaretskii <eliz@gnu.org>

1114 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1116 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1117 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1118 for some of that bug's symptoms can now cause Emacs to abort.
1119 Remove the workaround.
1120 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1121 The bug that caused SIGCHLD to get lost has been fixed, and the
1122 workaround for it can now cause Emacs to abort.
1124 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1126 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1127 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1128 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1130 2012-12-16 Romain Francoise <romain@orebokech.com>
1132 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1133 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1134 and copy ACL entries of file in addition to SELinux context if set.
1135 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1137 * Makefile.in (LIBACL_LIBS): New macro.

1152 * w32proc.c (new_child): Initialize input_file and
1153 pending_deletion members of the child.
1154 (delete_child): Delete the child's temporary input file, if any,
1155 that is pending deletion.
1156 (register_child): First argument is now pid_t.
1157 (record_infile, record_pending_deletion): New functions.
1158 (reap_subprocess): Fix a typo in DebPrint string.
1159 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1161 * fileio.c (internal_delete_file): Return an int again: non-zero
1162 if delete-file succeeds, zero otherwise.
1164 * lisp.h (internal_delete_file): Adjust prototype.
1166 * callproc.c (Fcall_process): Don't overwrite infile with result
1168 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1169 asynchronous subprocess, record the name of the input file name,
1171 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1172 delete the file, record it as pending deletion when the subprocess
1175 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1177 * editfns.c [HAVE_PWD_H]: Include grp.h.
1179 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1181 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1183 Fix permissions bugs with setgid directories etc. (Bug#13125)
1184 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1185 to mark it as a placeholder. The old value was often wrong.
1186 The only user of this attribute has been changed to use
1187 file-ownership-preserved-p instead, with its new group arg.
1188 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1190 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

1195 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1197 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1198 try to get accurate owner and group information from NT file
1199 security APIs. This is to make most callers of 'stat' and
1200 'lstat', which don't need that information, much faster.
1202 * dired.c (Ffile_attributes) [WINDOWSNT]:
1203 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1204 owner and group information from 'lstat'.
1206 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1208 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1209 as that confuses set-auto-coding, so insist on the head-read
1210 returning the full 1024 bytes. Let lseek compute the tail offset;
1211 less work for us. Do not ignore I/O errors when reading the tail.
1213 * xdisp.c: Minor style fixes.
1214 (init_iterator): Hoist assignment out of if-expression.
1215 (markpos_of_region): Callers now test for sign, not for -1.

1229 character in pattern when the buffer being searched is unibyte.
1232 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1234 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1235 files, fixing a regression from 24.2.
1236 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1238 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1240 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1241 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1242 Remove unnecessary S_ISLNK test, as (contra the comments) this
1243 function can't copy symlinks. Improve quality of error message
1244 when attempting to copy files that are neither regular files nor

1252 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1253 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1255 2012-12-12 Daniel Colascione <dancol@dancol.org>
1257 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1258 the dumped Emacs is not a sparse file, greatly improving Cygwin
1259 "make bootstrap" performance.
1261 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1263 * inotify.c (inotify_callback): Generate an Emacs event for every
1264 incoming inotify event.
1266 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1268 * xdisp.c (handle_face_prop): Fix logic of computing
1269 it->start_of_box_run_p.
1270 (append_space_for_newline): If the glyph row is R2L, reset the
1271 iterator's end_of_box_run_p flag before prepending the space glyph.
1272 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1273 iterator's start_of_box_run_p flag before prepending the stretch.
1274 (append_glyph, produce_image_glyph, append_composite_glyph)
1275 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1276 left_box_line_p and right_box_line_p flags of the glyph for R2L
1277 glyph rows. (Bug#13011)
1279 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1281 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
1282 if changed buffer is not shown in a window.
1283 * insdel.c (prepare_to_modify_buffer): Likewise.
1284 * window.c (replace_buffer_in_windows_safely): Do nothing
1285 if buffer is not shown in a window.

1291 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1292 encoded_file_name, which is what it is.
1294 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1326 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1327 (hinst): Remove unneeded extern declaration.
1328 (_start): Remove initialization of above variables; remove
1329 initialization of hinst, as cache_system_info now does that.

1440 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
1442 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
1443 DWORD_PTR, for compatibility with 64-bit builds.
1445 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
1446 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
1447 (system_process_attributes): Use SIZE_T rather than DWORD, for
1448 compatibility with 64-bit builds.
1450 2012-12-10 Christopher Schmidt <christopher@ch.ristopher.com>
1452 * lread.c (Vload_source_file_function): Doc fix (Bug#11647).
1454 2012-12-10 Eli Zaretskii <eliz@gnu.org>
1456 * indent.c (Fvertical_motion): If a display string will be
1457 displayed on the left or the right margin, don't consider it as a
1458 factor in cursor positioning. (Bug#13108)
1460 2012-12-10 Martin Rudalics <rudalics@gmx.at>
1462 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
1464 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>

1469 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1471 * w32.c (unsetenv): Return 0 if the input string is too long.
1473 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1475 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1476 * alloc.c (xputenv): New function.
1477 * dbusbind.c (Fdbus_init_bus):
1479 * xterm.c (x_term_init):
1480 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1481 * editfns.c (initial_tz): Move static var decl up.
1482 (tzvalbuf_in_environ): New static var.
1483 (init_editfns): Initialize these two static vars.
1484 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1485 Save old TZ value on stack, if it's small.
1486 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1487 instead, use xputenv+unsetenv to set and restore TZ.
1488 (environbuf): Remove static var. All uses removed.
1489 (Fset_time_zone_rule): Do not save TZ and environ;
1490 no longer needed here.
1491 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1492 Move to inside set_time_zone_rule; they don't need file scope any more.
1493 (set_time_zone_rule): Maintain the TZ=value string separately.
1494 (syms_of_editfns): Don't initialize initial_tz;
1495 init_editfns now does it.
1496 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1497 * lisp.h (xputenv): New decl.
1499 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1501 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1503 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1505 * w32.c (unsetenv, sys_putenv): New functions.
1507 2012-12-08 Chong Yidong <cyd@gnu.org>
1509 * editfns.c (Finsert_char): Make the error message more
1510 informative (Bug#12992).
1512 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1514 Simplify get_lim_data.
1515 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1516 Remove USG and vlimit methods; no longer used these days.
1517 Add #error catchall just in case.
1519 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1520 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1521 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1522 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1523 (deleted_pid_list, Fdelete_process, create_process)
1524 (record_child_status_change, handle_child_signal, deliver_child_signal)
1525 (init_process_emacs, syms_of_process):
1526 Assume SIGCHLD is defined.
1527 (parse_signal): Remove. All uses removed.
1528 (abbr_to_signal): New static function.
1529 (Fsignal_process): Use it to convert signal names to ints.
1530 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1531 kill (getpgrp (), ...).
1532 (emacs_sigaction_init): Assume SIGCHLD is defined.
1533 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1534 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1535 * syssignal.h (EMACS_KILLPG): Remove.
1536 All uses replaced by 'kill' with a negative pid.
1537 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1538 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1540 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1542 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1543 This will cause a production Emacs to dump core instead of
1546 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1548 * frame.c (make_frame): Do not set window's buffer to t.
1549 * window.c (Fsplit_window_internal): Likewise. Previously it was
1550 used to indicate that the window is being set up. Now we use
1551 set_window_buffer for all new windows, so the condition in ...
1552 (Fset_window_buffer): ... is always true and can be removed.
1554 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1556 Convenient macro to check whether the buffer is hidden.
1557 * buffer.h (BUFFER_HIDDEN_P): New macro.
1558 * frame.c (make_frame): Use it. Adjust comment.
1559 * buffer.c (candidate_buffer): New function.
1560 (Fother_buffer, other_buffer_safely): Use it.
1562 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1564 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1565 if the child process is still running. Instead, exit the wait
1566 loop and return zero. (Bug#13086)
1568 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1570 * frame.h (x_char_width, x_char_height): Remove prototypes.

1581 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1583 Fix a recently-introduced delete-process race condition.
1584 * callproc.c, process.h (record_kill_process):
1585 New function, containing part of the old call_process_kill.
1586 (call_process_kill): Use it.
1587 This does not change call_process_kill's behavior.
1588 * process.c (Fdelete_process): Use record_kill_process to fix a
1589 race condition that could cause Emacs to lose track of a child.
1591 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1593 Avoid code duplication between prev_frame and next_frame.
1594 * frame.c (candidate_frame): New function. Add comment.
1595 (prev_frame, next_frame): Use it. Adjust comment.
1597 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1599 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1600 fails, signal an error instead of continuing with an empty
1602 Encode expanded temp file pattern before passing it to mkstemp or
1605 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1606 Encode the file name before passing it to dostounix_filename, in
1607 case it will downcase it (under w32-downcase-file-names).
1610 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1612 Minor call-process cleanups.
1613 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1614 at the same time as other platforms, to simplify analysis.
1615 No need for fd0_volatile since we have synch_process_fd.
1616 Avoid needless emacs_close; arg is always negative.
1618 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1620 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1623 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1625 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1626 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1627 and mouse_face_hidden members to a bitfields.
1628 * frame.h (struct frame): Remove set-but-not-used space_width member.
1629 (FRAME_SPACE_WIDTH): Remove.
1630 * nsterm.m, w32term.c, xterm.c: Adjust users.
1631 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1632 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1633 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1634 members to a bitfields.
1636 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1638 Don't let call-process be a zombie factory (Bug#12980).
1639 Fixing this bug required some cleanup of the signal-handling code.
1640 As a side effect, this change also fixes a longstanding rare race
1641 condition whereby Emacs could mistakenly kill unrelated processes,
1642 and it fixes a bug where a second C-g does not kill a recalcitrant
1643 synchronous process in GNU/Linux and similar platforms.
1644 The patch should also fix the last vestiges of Bug#9488,
1645 a bug which has mostly been fixed on the trunk by other changes.
1646 * callproc.c, process.h (synch_process_alive, synch_process_death)
1647 (synch_process_termsig, sync_process_retcode):
1648 Remove. All uses removed, to simplify analysis and so that
1649 less consing is done inside critical sections.
1650 * callproc.c (call_process_exited): Remove. All uses replaced
1651 with !synch_process_pid.
1652 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1653 These take the role of what used to be in unwind-protect arg.
1655 (block_child_signal, unblock_child_signal):
1656 New functions, to avoid races that could kill innocent-victim processes.
1657 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1658 (call_process_kill): Record killed processes as deleted, so that
1659 zombies do not clutter up the system. Do this inside a critical
1660 section, to avoid a race that would allow the clutter.
1661 (call_process_cleanup): Fix code so that the second C-g works again
1662 on common platforms such as GNU/Linux.
1663 (Fcall_process): Create the child process in a critical section,
1664 to fix a race condition. If creating an asynchronous process,
1665 record it as deleted so that zombies do not clutter up the system.
1666 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1667 light of these changes. Omit unnecessary call to emacs_close
1668 before failure, as the unwind-protect code does that.
1669 * callproc.c (call_process_cleanup):
1670 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1671 * process.c (record_deleted_pid): New function, containing
1672 code refactored out of Fdelete_process.
1673 (Fdelete_process): Use it.
1674 (process_status_retrieved): Remove. All callers changed to use
1675 child_status_change.
1676 (record_child_status_change): Remove, folding its contents into ...
1677 (handle_child_signal): ... this signal handler. Now, this
1678 function is purely a handler for SIGCHLD, and is not called after
1679 a synchronous waitpid returns; the synchronous code is moved to
1680 wait_for_termination. There is no need to worry about reaping
1681 more than one child now.
1682 * sysdep.c (get_child_status, child_status_changed): New functions.
1683 (wait_for_termination): Now takes int * status and bool
1684 interruptible arguments, too. Do not record child status change;
1685 that's now the caller's responsibility. All callers changed.
1686 Reimplement in terms of get_child_status.
1687 (wait_for_termination_1, interruptible_wait_for_termination):
1688 Remove. All callers changed to use wait_for_termination.
1689 * syswait.h: Include <stdbool.h>, for bool.
1690 (record_child_status_change, interruptible_wait_for_termination):
1692 (record_deleted_pid, child_status_changed): New decls.
1693 (wait_for_termination): Adjust to API changes noted above.
1695 * bytecode.c, lisp.h (Qbytecode): Remove.
1696 No longer needed after 2012-11-20 interactive-p changes.
1698 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1700 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1701 the scroll margin, move point outside the margin. (Bug#13055)
1703 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1705 * gtkutil.c (my_log_handler): New function.
1706 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1708 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1710 * lisp.h (modify_region): Rename to...
1711 (modify_region_1): ...new prototype.
1712 * textprop.c (modify_region): Now static. Adjust users.
1713 * insdel.c (modify_region): Rename to...
1714 (modify_region_1): ...new function to work with current buffer.
1715 Adjust comment and users. Use true and false for booleans.
1717 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1719 * alloc.c (free_save_value): New function.
1720 (safe_alloca_unwind): Use it.
1721 * lisp.h (free_save_value): New prototype.
1722 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1724 (save_excursion_restore): Adjust to match saved data structure.
1725 Use free_save_value to offload some work from GC. Drop obsolete
1728 2012-12-03 Chong Yidong <cyd@gnu.org>
1730 * fileio.c (Vauto_save_list_file_name): Doc fix.
1732 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1734 * w32fns.c: Remove prototype of atof.
1735 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1737 (file_dialog_callback): Make it UINT_PTR.
1739 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1742 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1743 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1746 2012-12-03 Glenn Morris <rgm@gnu.org>
1748 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1750 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1752 Fix xpalloc confusion after memory is exhausted.
1753 * alloc.c (xpalloc): Comment fix.
1754 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1755 and signals an error, do not clear charset_table_size, as
1756 charset_table is still valid.
1757 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1759 Use execve to avoid need to munge environ (Bug#13054).
1760 * callproc.c (Fcall_process):
1761 * process.c (create_process):
1762 Don't save and restore environ; no longer needed.
1763 * callproc.c (child_setup):
1764 Use execve, not execvp, to preserve environ.
1766 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1768 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1770 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1772 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1773 display for sliced images (Bug#10500).
1775 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1777 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1779 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1780 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1782 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1784 * xdisp.c (window_outdated): Remove eassert since it hits
1785 some suspicious corner cases (see Bug#13007 and Bug#13012).
1786 (mode_line_update_needed): New function.
1787 (redisplay_internal, redisplay_window): Use it.
1788 (ensure_selected_frame): New function.
1789 (redisplay_internal, unwind_redisplay): Use it.
1790 (redisplay_internal): Move comment about buffer_shared...
1791 (buffer_shared_and_changed): ...near to its real use.
1793 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1795 * callproc.c (Fcall_process): Don't misreport vfork failure.
1797 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1799 * callproc.c (Fcall_process): Fix vfork portability problems.
1800 Do not assume that fd[0], count, filefd, and save_environ survive
1801 vfork. Fix bug whereby wrong errno value could be reported for
1802 pipe failure. Some minor cleanups, too, as follows. Move buf and
1803 bufsize to the context where they're needed. Change new_argv to
1804 be of type char **, as this is more convenient and avoids casts.
1805 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1806 Now local constants, not macros.
1808 2012-11-18 Kenichi Handa <handa@gnu.org>
1810 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1811 for the variable "f".
1813 2012-11-13 Kenichi Handa <handa@gnu.org>
1815 * font.c (font_unparse_xlfd): Exclude special characters from the
1816 generating XLFD name.
1818 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1820 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
1821 * dired.c (stat_uname, stat_gname):
1822 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1824 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1828 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1829 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1830 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1831 * lread.c (readbyte_from_file): Assume EINTR is defined.
1832 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1833 Assume EIO and EAGAIN are defined.
1834 * unexcoff.c (write_segment): Assume EFAULT is defined.
1836 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1838 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1841 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1842 highlighting on the frame was cleared. Prevents assertion
1843 violations when repeatedly clicking on the "Top" link of the
1844 "bread-crumbs" in Info buffers.
1846 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1848 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1850 2012-11-24 Ken Brown <kbrown@cornell.edu>
1852 * keyboard.c (HAVE_MOUSE):
1853 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1854 were always defined.
1856 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1858 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1859 between bpos_covered and bpos_max. This fixes cursor display when
1860 several display strings follow each other.
1862 * .gdbinit (pgx): If the glyph's object is a string, display the
1863 pointer to string data, rather than the value of the string object
1864 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1866 * indent.c (Fvertical_motion): If the starting position is covered
1867 by a display string, return to one position before that, to avoid
1868 overshooting it inside move_it_to. (Bug#12930)
1870 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1872 * frame.h (struct frame): Remove display_preempted member

1875 * w32menu.c (pending_menu_activation): Remove since not
1877 (set_frame_menubar): Adjust user.
1878 * w32term.h (struct x_output): Drop outdated #if 0 code.
1879 (struct w32_output): Use bitfields for explicit_parent,
1880 asked_for_visible and menubar_active members.
1881 Drop unused pending_menu_activation member.
1882 * xterm.h (struct x_output): Drop outdated #if 0 code.
1883 Use bitfields for explicit_parent, asked_for_visible,
1884 has_been_visible and net_wm_state_hidden_seen members.
1886 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1888 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1889 of a literal "/". (Bug#12955)
1890 (gl-stamp): Invoke fc.exe directly, not through cmd.
1892 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1894 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1895 * dired.c: Assume HAVE_DIRENT_H.
1896 (NAMLEN): Remove, replacing with ...
1897 (dirent_namelen): New function. All uses changed. Use the GNU macro
1898 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1899 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1900 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1901 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1903 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1904 * ndir.h: Rename to ../nt/inc/dirent.h.
1905 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1906 Do not include <dirent.h>; no longer needed.
1907 * w32.c: Include <dirent.h> rather than "ndir.h".
1909 2012-11-23 Chong Yidong <cyd@gnu.org>
1911 * xftfont.c (xftfont_open): Remove duplicate assignment.
1913 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1915 * alloc.c (Fgarbage_collect): Unblock input after clearing
1916 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1917 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1918 * msdos.c (IT_frame_up_to_date): Use it here...
1919 * w32term.c (w32_frame_up_to_date): ...here...
1920 * xterm.c (XTframe_up_to_date): ...and here...
1921 * nsterm.m (ns_frame_up_to_date): ...but not here.
1922 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1924 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1925 Do not check whether GC is in progress.
1927 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1929 * xdisp.c (window_buffer_changed): New function.
1930 (update_menu_bar, update_tool_bar): Use it to
1931 simplify large 'if' statements.

1933 'tail' and 'frame' local variables.
1935 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1937 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1938 with Windows system header.
1940 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1942 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1943 * alloc.c: Assume unistd.h exists.
1944 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1945 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1946 (getwd) [USG]: Remove; no longer needed.
1947 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1948 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1949 * w32.h (getcwd): Remove decl.
1951 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1953 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1954 Make it set selected_window as well.
1955 (update_tool_bar): Use it.
1957 2012-11-21 Ken Brown <kbrown@cornell.edu>
1959 * emacs.c (main): Set the G_SLICE environment variable for all
1960 Cygwin builds, not just GTK builds. See
1961 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1963 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1965 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1966 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1967 Define for the MSVC compiler.
1969 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1971 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1972 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1973 dostounix_filename. Prevents crashes down the road, because
1974 dostounix_filename assumes it gets a unibyte string.
1975 Reported by Michel de Ruiter <michel@sentient.nl>, see
1976 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1978 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1983 * eval.c (Fcommandp): Ignore Qunbound.
1984 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1985 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1986 Test NILP rather than Qunbound.
1987 (Ffmakunbound): Set to Qnil.
1988 (Fsymbol_function): Never signal an error.
1989 (Finteractive_form): Ignore Qunbound.
1991 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1993 * eval.c (interactive_p): Remove no-longer-used decl.
1995 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1997 * xdisp.c (buffer_shared): Adjust comment.
1998 (buffer_shared_and_changed): New function.
1999 (prepare_menu_bars, redisplay_internal): Use it to
2000 decide whether all windows or frames should be updated.
2001 (window_outdated): New function.
2002 (text_outside_line_unchanged_p, redisplay_window): Use it.
2003 (redisplay_internal): Likewise. Fix indentation.
2005 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2007 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2008 (syms_of_eval): Remove corresponding defsubr.
2009 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2011 2012-11-19 Daniel Colascione <dancol@dancol.org>
2013 * w32fns.c (Fx_file_dialog):
2014 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2015 cygwin_convert_file_name*.
2017 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2018 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2020 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2022 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2024 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2026 * w32select.c: Include w32common.h before w32term.h, so that
2027 windows.h gets included before w32term.h uses some of its
2028 features, see below.
2030 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2032 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2034 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2036 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2038 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2039 (ns_select): Return at once if events are held (Bug#12834).
2041 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2043 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2044 Needed following 2012-10-20 change. (Bug#12902)
2046 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2048 * w32proc.c (waitpid): Remove unused label get_result.
2050 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2052 * makefile.w32-in (SYSWAIT_H): New macro.
2053 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2054 ($(BLD)/sysdep.$(O)): Update dependencies.
2056 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2058 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2059 * callproc.c (relocate_fd): Assume F_DUPFD.
2060 * emacs.c, term.c (O_RDWR): Remove.
2061 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2062 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2063 * nsterm.m: Assume <fcntl.h> exists.
2064 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2065 (create_pty, Fmake_network_process, server_accept_connection)
2066 (wait_reading_process_output, init_process_emacs):
2068 (wait_reading_process_output): Put in a special case for WINDOWSNT
2069 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2070 It's not clear this is needed, but it's a more-conservative change.
2071 (create_process): Assume FD_CLOEXEC.
2072 (create_process, create_pty): Assume O_NOCTTY.
2073 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2074 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2075 Omit if not DOS_NT, since F_GETFL is not defined there.
2076 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2077 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2079 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2080 lack it, since gnulib guarantees this.
2081 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2083 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2085 * w32.c (faccessat): Pretend that directories have the execute bit
2086 set. Emacs expects that, e.g., in files.el:cd-absolute.
2088 * w32proc.c (create_child): Don't clip the PID of the child
2089 process to fit into an Emacs integer, as this is no longer a
2091 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2092 reaping only the process specified by PID argument, if that is
2093 positive. Use PID instead of dead_child to know which process to
2094 reap. Wait for the child to die only if WNOHANG is not in
2096 (sys_select): Don't set dead_child.
2098 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2099 as it is no longer needed.
2101 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2103 (record_child_status_change): Remove the setting of
2104 record_at_most_one_child for the !WNOHANG case.
2106 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2108 Fix problems in ns port found by static checking.
2109 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2110 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2111 not to process group.
2112 (ns_select): Use emacs_write, not write, as that's more robust
2113 in the presence of signals.
2114 (fd_handler:): Check for read errors.
2116 2012-11-16 Glenn Morris <rgm@gnu.org>
2118 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2120 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2122 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2124 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2126 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2127 use the same value of thread handle.
2128 (start_timer_thread): If the timer thread exited (due to error),
2129 clean up by closing the two handles it used. Duplicate the caller
2130 thread's handle here, so it gets duplicated only once, when
2131 launching the timer thread. Set priority of the timer thread, not
2133 (getitimer): Don't duplicate the caller thread's handle here.
2136 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2138 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2141 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2143 Remove no-longer-used pty_max_bytes variable.
2144 * process.c (pty_max_bytes): Remove; unused.
2145 (send_process): Do not set it.
2147 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2149 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2150 Update dependencies.
2152 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2154 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2155 This follows up on the 2012-09-29 patch that removed indirection
2156 for the 'function' field. Reported by Sergey Vinokurov in
2157 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2159 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2161 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2162 different name, as the MS runtime does not have such a function,
2163 and probably never will.) All callers changed. Ignore DIRFD
2164 value if PATH is an absolute file name, to match Posix spec
2165 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2168 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2170 * xdisp.c (echo_area_display, redisplay_internal):
2171 Omit redundant check whether frame_garbaged is set.
2173 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2175 Use faccessat, not access, when checking file permissions (Bug#12632).
2176 This fixes a bug that has been present in Emacs since its creation.
2177 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2178 which must set some sort of record. (Torek's bug report was against
2179 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2180 same common flaw.) See Torek's Usenet posting
2181 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2182 Posted: Fri Apr 8 14:18:56 1983.
2183 * Makefile.in (LIB_EACCESS): New macro.
2185 * callproc.c (init_callproc):
2186 * charset.c (init_charset):
2187 * fileio.c (check_existing, check_executable, check_writable)
2189 * lread.c (openp, load_path_check):
2190 * process.c (allocate_pty):
2192 Use effective UID when checking permissions, not real UID.
2193 * callproc.c (init_callproc):
2194 * charset.c (init_charset):
2195 * lread.c (load_path_check, init_lread):
2196 Test whether directories are accessible, not merely whether they exist.
2197 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2198 * fileio.c (check_existing, check_executable, check_writable)
2200 Use symbolic names instead of integers for the flags, as they're
2202 (check_writable): New arg AMODE. All uses changed.
2203 Set errno on failure.
2204 (Ffile_readable_p): Use faccessat, not stat + open + close.
2205 (Ffile_writable_p): No need to call check_existing + check_writable.
2206 Just call check_writable and then look at errno. This saves a syscall.
2207 dir should never be nil; replace an unnecessary runtime check
2208 with an eassert. When checking the parent directory of a nonexistent
2209 file, check that the directory is searchable as well as writable, as
2210 we can't create files in unsearchable directories.
2211 (file_directory_p): New function, which uses 'stat' on most platforms
2212 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2213 (Ffile_directory_p, Fset_file_times): Use it.
2214 (file_accessible_directory_p): New function, which uses a single
2215 syscall for efficiency.
2216 (Ffile_accessible_directory_p): Use it.
2217 * xrdb.c (file_p): Use file_directory_p.
2218 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2219 * lread.c (openp): When opening a file, use fstat rather than
2220 stat, as that avoids a permissions race. When not opening a file,
2221 use file_directory_p rather than stat.
2222 (dir_warning): First arg is now a usage string, not a format.
2223 Use errno. All uses changed.
2224 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2225 that merely introduced a race.
2226 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2227 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2228 and similarly for the other O_* flags.
2229 * w32.c (sys_faccessat): Rename from sys_access and switch to
2230 faccessat's API. All uses changed.
2231 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2232 (magic_db): Rename from magic_file_p.
2233 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2234 char *, so that we don't have to test for file existence
2235 separately from opening the file for reading. This removes a race
2236 fixes a permission-checking problem, and simplifies the code.
2238 (file_p): Remove; no longer needed.
2240 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2242 Omit glyphs initialization at startup.
2243 * dispnew.c (glyphs_initialized_initially_p): Remove.
2244 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2245 (Fredraw_frame): Move actual code from here...
2246 (redraw_frame): ...to here. Add eassert. Adjust comment.
2247 (Fredraw_display): Use redraw_frame.
2248 * xdisp.c (clear_garbaged_frames): Likewise.
2250 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2252 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2253 passed to pint2str and pint2hrstr to be at most the size of the
2254 frame's decode_mode_spec_buffer. This avoids crashes with very
2255 large values of FIELD_WIDTH argument to decode_mode_spec.
2258 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2260 Fix a race with verify-visited-file-modtime (Bug#12863).
2261 Since at least 1991 Emacs has ignored an mtime difference of no
2262 more than one second, but my guess is that this was to work around
2263 file system bugs that were fixed long ago. Since the race is
2264 causing problems now, let's remove that code.
2265 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2266 whose time stamp is off by no more than a second. Insist that the
2267 file time stamps match exactly.
2269 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2271 * frame.h (struct frame): Convert external_tool_bar member to
2272 1-bit unsigned bitfield.
2273 * termhooks.h (struct terminal): Remove mouse_moved member since
2274 all users are long dead. Adjust comment on mouse_position_hook.
2276 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2278 Simplify by using FOR_EACH_FRAME here and there.
2279 * frame.c (next_frame, prev_frame, other_visible_frames)
2280 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2281 * w32term.c (x_window_to_scroll_bar): Likewise.
2282 * window.c (window_list): Likewise.
2283 * xdisp.c (x_consider_frame_title): Likewise.
2284 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2285 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2286 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2287 * xmenu.c (menubar_id_to_frame): Likewise.
2288 * xselect.c (frame_for_x_selection): Likewise.
2289 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2290 (x_window_to_menu_bar): Likewise.
2291 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2293 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2295 * data.c (Qdefalias_fset_function): Now static.
2297 Another tweak to vectorlike_header change.
2298 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2299 Remove, and replace all uses with ...
2300 (next_in_free_list, set_next_in_free_list):
2301 New functions, which respect C's aliasing rules better.
2303 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2305 * window.c (list4i): Rename from 'quad'. All uses changed.
2306 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2308 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2310 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2311 warning about mixing declarations and code in ISO C90.
2313 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2315 * window.c (Fsplit_window_internal): Set combination limit of
2316 new parent window to t iff Vwindow_combination_limit is t;
2317 fixing a regression introduced with the change from 2012-09-22.
2318 (Fset_window_combination_limit): Fix doc-string.
2320 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2322 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2323 amount when the scroll margins are too large. When scrolling
2324 backwards in the buffer, give up if cannot reach point or the
2325 scroll margin within a reasonable number of screen lines.
2326 Fixes point position in window under scroll-up/down-aggressively when
2327 point is positioned many lines beyond the window top/bottom.
2330 * ralloc.c (relinquish): If real_morecore fails to return memory
2331 to the system, don't crash; instead, leave the last heap
2332 unchanged and return. (Bug#12774)
2334 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2336 * lisp.h (AUTOLOADP): New macro.
2337 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2338 * data.c (Ffset): Remove special ad-advice-info handling.
2339 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2341 (Finteractive_form): Simplify.
2342 (Fquo): Don't insist on having at least 2 arguments.
2343 (Qdefalias_fset_function): New var.

2362 Tweak last vectorlike_header change.
2363 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2364 vectorlike object on the free list. This is introduced to avoid
2365 some (but not all) pointer casting and aliasing problems, see
2366 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2367 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

2371 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2373 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

2399 special hash function containing a comparison that always yields 1.
2401 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2403 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2404 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2405 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2408 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2410 * image.c (xpm_make_color_table_h): Fix compiler error because
2411 make_hash_table changed.
2413 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2415 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2417 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2419 Use ad-hoc comparison function for the profiler's hash-tables.
2420 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2421 (make_log): Use them.
2422 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2423 call Fequal any more.

2432 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2433 (hash_lookup, hash_remove_from_table): Move assertion checking of
2434 hashfn result here. Check hash-equality before calling cmpfn.

2447 value of w32-scroll-lock-modifier is neither nil nor one of the
2448 known key modifiers. (Bug#12806)
2450 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2452 Shrink struct vectorlike_header to the only size field.
2453 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2455 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

2476 (allocate_vector_from_block): Simplify.
2477 (PSEUDOVECTOR_NBYTES): Replace with...

2480 (allocate_vectorlike): Likewise.
2481 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2482 Add easserts. Adjust XSETPVECTYPESIZE usage.
2483 (allocate_buffer): Use BUFFER_PVEC_INIT.
2484 (live_vector_p): Adjust to match large vector.
2485 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2486 * buffer.h (struct buffer): Add next member.

2497 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2499 * keyboard.c (event_to_kboard): Do not dereference
2500 frame_or_window field of SELECTION_REQUEST_EVENT
2501 and SELECTION_CLEAR_EVENT events (Bug#12814).
2502 * xterm.h (struct selection_input_event): Adjust comment.
2504 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2506 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2507 such as Scroll Lock, if the respective keys are treated as
2508 function keys, not as modifiers. This avoids destroying non-ASCII
2509 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2511 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2513 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2515 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2517 Restore some duplicate definitions (Bug#12814).
2518 This undoes part of the 2012-11-03 changes. Some people build
2519 with plain -g rather than with -g3, and they need the duplicate
2520 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2521 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2522 Define as macros, as well as as enums or as constants.
2524 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2526 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2527 to keypad keys (Bug#12816).
2529 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2531 Minor adjustments of recently-changed frame functions.
2532 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2533 known to be a frame (we're in the FRAMEP branch).
2534 * lisp.h (Qframep): Remove decl. frame.h declares this.
2535 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2536 since they're meant for Lisp fixnum values.
2538 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2540 * window.c (Fwindow_combination_limit): Revert to the only
2541 required argument and adjust docstring as suggested in
2542 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2543 by Martin Rudalics <rudalics@gmx.at>.
2545 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2547 Widely used frame validity and checking functions.
2548 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2549 * frame.c (decode_live_frame, decode_any_frame): New functions.
2550 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2551 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2552 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

2560 * lisp.h (frame_buffer_predicate): Remove prototype.
2561 * buffer.c (Fother_buffer): Use decode_any_frame.
2562 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2563 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2564 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2565 (Fclose_font, Ffont_info): Use decode_live_frame.
2566 * fontset.c (check_fontset_name): Likewise.
2567 * terminal.c (Fframe_terminal): Likewise.
2568 * w32fns.c (check_x_frame): Likewise.
2569 * window.c (Fminibuffer_window, Fwindow_at)
2570 (Fcurrent_window_configuration): Likewise.
2571 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2572 Likewise. Allow zero number of arguments. Adjust docstring.
2573 * dispnew.c (Fredraw_frame): Likewise.
2574 * xfaces.c (frame_or_selected_frame): Remove.
2575 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2576 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2577 (Fframe_face_alist): Use decode_live_frame.
2578 * xfns.c (check_x_frame): Likewise.
2580 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2582 * window.c (quad): New function.
2583 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2584 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2585 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2586 (Fwindow_line_height): Use it.
2587 (Fwindow_fringes): Use list3.
2588 (Fwindow_scroll_bars): Use list4.
2589 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2590 (Fwindow_combination_limit): Allow zero number of arguments.
2592 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2594 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2596 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2597 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2598 file descriptor 2 for standard error. (Bug#12805)
2600 2012-11-05 Chong Yidong <cyd@gnu.org>
2602 * process.c (wait_reading_process_output): Revert previous change.
2604 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2606 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2607 This removes code that has been obsolete since around 1990.
2608 * callproc.c (Fcall_process):
2610 * process.c (create_process):
2611 * term.c (dissociate_if_controlling_tty):
2612 Assume setsid exists.
2613 * callproc.c (child_setup): Assume setpgid exists and behaves as
2614 per POSIX.1-1988 or later.
2615 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2616 * emacs.c (shut_down_emacs):
2617 * sysdep.c (sys_suspend, init_foreground_group):
2618 Assume getpgrp behaves as per POSIX.1-1998 or later.
2619 * msdos.c (setpgrp): Remove.
2620 (tcgetpgrp, setpgid, setsid): New functions.
2621 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2622 * term.c (no_controlling_tty): Remove; unused.
2623 * w32proc.c (setpgrp): Remove.
2624 (setsid, tcgetpgrp): New functions.
2626 Simplify by assuming __fpending.
2627 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2628 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2629 Do not assume that __fpending's result fits in int.
2631 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2633 Remove EMACS_OUTQSIZE+sleep hack.
2634 * dispnew.c (update_frame_1): Remove hack for terminals slower
2635 than 2400 bps, which throttled Emacs by having it sleep.
2636 This code hasn't worked since at least 2007, when the multi-tty stuff
2637 was added, and anyway those old terminals are long dead.
2638 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2639 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2641 Fix data-loss with --version (Bug#9574).
2642 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2643 as we can't assume that emacs_strerror is initialized, and strerror
2644 is good enough here.
2645 (main): Invoke atexit earlier, to catch earlier instances of
2646 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2648 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2650 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2651 (keyDown): Remap keypad keys to X11 virtual key codes.
2653 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2655 Fix data-loss with --batch (Bug#9574).
2656 * emacs.c: Include <close-stream.h>.
2657 (close_output_streams): New function.
2658 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2659 and handles errors appropriately.
2660 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2663 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2664 The symptom is a diagnostic "GLib-WARNING **: In call to
2665 g_spawn_sync(), exit status of a child process was requested but
2666 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2667 waitpid(), so exit status can't be returned." The diagnostic
2668 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2669 The real bug is a race condition between Emacs and glib: Emacs
2670 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2671 so that glib can't find it. Work around the bug by invoking
2672 waitpid only on subprocesses that Emacs itself creates.
2673 * process.c (create_process, record_child_status_change):
2674 Don't use special value -1 in pid field, as the caller now must
2675 know the pid rather than having the callee infer it.
2676 The inference was sometimes incorrect anyway, due to another race.
2677 (create_process): Set new 'alive' member if child is created.
2678 (process_status_retrieved): New function.
2679 (record_child_status_change): Use it.
2680 Accept negative 1st argument, which means to wait for the
2681 processes that Emacs already knows about. Move special-case code
2682 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2683 processes that have already been waited for, by testing and
2684 clearing new 'alive' member.
2685 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2686 now does this internally.
2687 (handle_child_signal): Let record_child_status_change do all
2688 the work, since we do not want to reap all exited child processes,
2689 only the child processes that Emacs itself created.
2690 * process.h (Lisp_Process): New boolean member 'alive'.
2692 Omit duplicate definitions no longer needed with gcc -g3.
2693 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2694 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2695 Define only as macros. There's no longer any need to also define
2696 these symbols as enums or as constants, since we now assume
2697 gcc -g3 when debugging.
2699 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2701 * lisp.mk: Adjust comments to the fact that term/internal is now
2702 loaded from loadup.el.
2704 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2705 (msdos_fatal_signal): New function.
2706 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2709 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2710 for GCC versions before 4.
2711 (emacs_raise): Define to call msdos_fatal_signal.
2713 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2714 iterator when starting in the middle of a display or overlay
2717 2012-11-03 Chong Yidong <cyd@gnu.org>
2719 * process.c (wait_reading_process_output): Clean up the last
2722 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2724 * process.c (wait_reading_process_output): Avoid a race condition
2725 with SIGIO delivery (Bug#11536).
2727 2012-11-03 Chong Yidong <cyd@gnu.org>
2729 * buffer.c (cursor_type): Untabify docstring.
2731 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2733 * frame.h (struct frame): Drop can_have_scroll_bars member
2734 which is meaningless for a long time. Adjust comments.
2735 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2736 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2738 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2740 * window.c (decode_next_window_args): Update window arg after
2741 calling decode_live_window and so fix crash reported at
2742 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2743 by Juanma Barranquero <lekktu@gmail.com>.
2744 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2745 * font.c (Ffont_at): Likewise.
2747 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2749 * widget.c (resize_cb): New function.
2750 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2751 (EmacsFrameResize): Check if all is up to date before changing frame
2754 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2756 Implement backtrace output for fatal errors on MS-Windows.
2757 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2758 (BACKTRACE_LIMIT_MAX): New macro.
2759 (w32_backtrace): New function.
2760 (emacs_abort): Use w32_backtrace when the user chooses not to
2761 attach a debugger. Update the text of the abort dialog.
2763 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2765 Window-related stuff cleanup here and there.
2766 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2767 Use decode_any_window.
2768 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2769 * xdisp.c (Fformat_mode_line): Likewise.

2775 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2776 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2779 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2781 Remove pad from struct input_event.
2782 * termhooks.h (struct input_event): Remove padding field.
2784 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2785 member is never cons for a long time. Adjust comment.
2786 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2787 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2788 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2789 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2791 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2793 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2795 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2797 Fix crash when using Emacs as commit editor for git (Bug#12697).
2798 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2799 and it is configured in conf_post.h.
2800 (Fcall_process): Don't invoke both setsid and setpgid; the former
2801 is enough, if it exists.
2802 * callproc.c (Fcall_process, child_setup):
2803 * process.c (create_process): Use setpgid.
2804 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2806 * dispnew.c (init_display): Initialize the foreground group
2807 if we are running a tty display.
2808 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2809 * lisp.h (init_foreground_group): New decl.
2810 * sysdep.c (inherited_pgroup): New static var.
2811 (init_foreground_group, tcsetpgrp_without_stopping)
2812 (narrow_foreground_group, widen_foreground_group): New functions.
2813 (init_sys_modes): Narrow foreground group.
2814 (reset_sys_modes): Widen foreground group.
2816 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2818 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2820 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2822 * minibuf.c (read_minibuf): Restore current buffer since
2823 choose_minibuf_frame calling Fset_frame_selected_window may
2824 change it (Bug#12766).
2826 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2828 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2830 2012-10-30 Kenichi Handa <handa@gnu.org>
2832 * font.c (Ffont_at): If WINDOW is specified and it is not
2833 displaying the current buffer, signal an error.
2835 2012-10-29 Daniel Colascione <dancol@dancol.org>
2837 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2838 In preparation for fixing bug#12739, move these functions from
2841 * coding.h, coding.c: ... to here, and compile them only when
2842 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2843 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2845 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2847 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2848 (timer_loop, getitimer, setitimer): Use it instead of
2849 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2851 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2854 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2856 * nsterm.m (NO_APPDEFINED_DATA): New define.
2857 (last_appdefined_event_data): New variable
2858 (last_appdefined_event): Remove.
2859 (ns_select): Initialize t from last_appdefined_event_data instead
2860 of [last_appdefined_event data1].
2861 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2862 remove last_appdefined_event (Bug#12698).
2864 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2866 * frame.c (x_set_font): Catch internal error.
2868 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2870 Avoid overflow in w32 implementation of interval timers.
2871 When possible, for ITIMER_PROF count only times the main thread
2873 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2874 'volatile ULONGLONG' types. All the other data which was
2875 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2876 (GetThreadTimes_Proc): New typedef.
2877 (w32_get_timer_time): New function, returns a suitable time value
2879 (timer_loop): Enter critical section when accessing ULONGLONG
2880 values of the itimer_data struct, as these accesses are no longer
2881 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2882 Remove unused variable.
2883 (init_timers): Initialize s_pfn_Get_Thread_Times.
2884 (start_timer_thread): Don't assign itimer->caller_thread here.
2885 (getitimer): Assign itimer->caller_thread here.
2886 (setitimer): Always call getitimer to get the value of ticks_now.
2887 (sys_spawnve): Avoid compiler warning about format mismatch.
2889 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2891 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2892 mouse movement events if the menu bar is active. This avoids
2893 producing a busy "hour-glass" cursor by Windows if the mouse
2894 pointer is positioned over a tooltip shown for some menu item.
2896 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2898 Don't assume process IDs fit in int.
2899 * emacs.c (shut_down_emacs) [!DOS_NT]:
2900 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2901 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2902 Use pid_t, not int, to store process IDs, as 'int'
2903 is not wide enough on a few platforms (e.g., AIX and IRIX).
2905 2012-10-23 Kenichi Handa <handa@gnu.org>
2907 The following change is to make face-font-rescale-alist work
2908 correctly for non-ASCII fonts.
2910 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2911 (font_open_for_lface): Handle Vface_font_rescale_alist.
2913 2012-10-23 Chong Yidong <cyd@gnu.org>
2915 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2917 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2921 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2923 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2926 2012-10-21 Glenn Morris <rgm@gnu.org>
2928 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2930 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2932 Port to OpenBSD 5.1.
2933 * frame.c (Fmouse_position, Fmouse_pixel_position):
2934 * xdisp.c (produce_stretch_glyph):
2935 Declare local vars only when they're needed.
2936 This is clearer and avoids a warning on OpenBSD about unused vars.
2937 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2938 This is safer, and avoids OpenBSD warnings about unused vars.
2939 * keyboard.c (record_menu_key): Remove unnecessary decl.
2940 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2941 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2942 as our definition clashes with OpenBSD's.
2943 * xfaces.c (load_face_colors, check_lface_attrs)
2944 (get_lface_attributes_no_remap, get_lface_attributes)
2945 (lface_fully_specified_p, x_supports_face_attributes_p)
2946 (tty_supports_face_attributes_p, face_fontset, realize_face)
2947 (realize_x_face, realize_tty_face):
2948 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2949 merely Lisp_Object *. This is more informative and avoids
2950 a warning on OpenBSD about accessing beyond an object's size.
2952 2012-10-20 Chong Yidong <cyd@gnu.org>
2954 * lread.c (Fload): Doc fix (Bug#12592).
2956 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2958 * font.c (Ffont_at): Fix previous change.
2960 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2962 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2963 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

2980 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2981 (staticpro): If we run out of staticpro slots, die with an
2982 informative error instead of just calling emacs_abort.
2984 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2986 Fix two flaws reported by Dmitry Antipov.

3107 * fileio.c (Fwrite_region): Avoid race condition if a file is
3108 removed or renamed by some other process immediately after Emacs
3109 writes it but before Emacs stats it. Do not assume that stat (or

3197 * marker.c (cached_modiff): EMACS_INT, not int.
3199 * w32select.c (waiting_for_input): Declare by including "keyboard.h"

3241 since unsigned is guaranteed to have that behavior and signed is not.
3242 (read_char): Use ptrdiff_t for string length.
3243 (get_input_pending): Remove first argument, since it was always
3244 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3245 and behave as if it had that value. Return new value of
3246 input_pending. All callers changed.
3247 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3248 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3275 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3277 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3279 * commands.h (immediate_quit): Remove duplicate decl.
3281 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3283 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3286 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3288 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3290 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3291 match what GetLastError returns. Explain why the function is
3294 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3295 'is_tooltip_frame', to avoid confusion with its global namesake.
3297 2012-10-08 Daniel Colascione <dancol@dancol.org>
3299 * xdisp.c (start_hourglass): Call w32_note_current_window when
3300 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3301 build that caused Emacs to display the hourglass cursor forever.
3303 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3304 which is broken under remote desktop, calculate the number of
3305 colors available for a display based on the display's number of
3306 planes and number of bits per pixel per plane. (bug#10397).
3308 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3310 * nsfont.m (Vfonts_in_cache): New variable.
3311 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3312 are used. Add cached fonts to Vfonts_in_cache.
3313 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3315 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3317 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3319 (FONT_H): Define after FRAME_H.
3320 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3321 Update dependencies.
3323 * w32term.c: Remove leftover declaration of keyboard_codepage.
3325 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3327 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3328 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3329 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3330 (GLOBAL_SOURCES): Add cygw32.c.
3331 ($(BLD)/unexw32.$(O)):
3333 ($(BLD)/w32console.$(O)):
3334 ($(BLD)/w32fns.$(O)):
3335 ($(BLD)/w32heap.$(O)):
3336 ($(BLD)/w32menu.$(O)):
3337 ($(BLD)/w32proc.$(O)): Add w32common.h.
3339 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3341 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3343 2012-10-08 Daniel Colascione <dancol@dancol.org>
3345 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3346 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3347 accidental message numbering hole. Change other messages to
3350 * w32select.h (HAVE_W32SELECT): Remove.
3352 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3353 w32common.h instead of w32heap.h.
3355 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3356 (get_allocation_unit, get_processor_type, get_w32_major_version)
3357 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3358 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3359 (OS_NT, os_subtype, cache_system_info): Move declarations to
3362 * w32heap.c: Include w32common.h.
3363 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3364 (w32_minor_version, w32_build_number, w32_subtype):
3365 Remove duplicate definitions.
3367 * w32fns.c: Include w32common.h; include w32heap.h only in
3370 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3371 Use `report_file_error' instead of `error' in order to better
3372 inform users of what went wrong. Increase NTGUI_UNICODE file
3373 dialog box file name length to 32k, the maximum allowed by the NT
3376 * w32common.h: New file.
3377 (ROUND_UP, ROUND_DOWN, get_page_size)
3378 (get_allocation_unit, get_processor_type, get_w32_major_version)
3379 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3380 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3381 (OS_NT, os_subtype, cache_system_info): Move here.
3383 * unexw32.c, unexcw.c: Include w32common.h.
3385 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3386 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3387 to call syms_of_w32select.
3389 * cygw32.h: Remove obsolete EXFUN declarations.
3391 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3393 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3394 of w32inevt.o from SOME_MACHINE_OBJECTS.
3396 2012-10-08 Daniel Colascione <dancol@dancol.org>
3398 * image.c: Permanent fix for JPEG compilation issue --- limit
3399 jpeglib `boolean' redefinition to Cygwin builds.
3401 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3403 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3405 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3408 2012-10-08 Daniel Colascione <dancol@dancol.org>
3410 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3411 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3412 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3413 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3414 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3415 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3416 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3417 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3418 now a supported configuration.
3420 * Makefile.in: consolidate image variables into LIBIMAGE; add
3421 W32_OBJ and W32_LIBS. Compile new files.
3424 (_DebPrint) declare tracing facility for W32 debugging. We need
3425 to unify tracing later.
3427 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3428 unconditional use of W32 Unicode functions. Cygwin runs only on
3429 100% Unicode operating systems.
3431 * cygw32.c: New file. Define Cygwin-specific facilities.
3432 (Fcygwin_convert_path_to_windows)
3433 (Fcygwin_convert_path_from_windows): New user functions for
3434 accessing Cygwin path-munging routines.
3436 * cygw32.h: New file.
3437 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3438 UTF-16LE strings temporarily inside non-Lisp-visible string
3441 (w32_strerror): Just what it says on the tin.
3443 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3444 also run for Cygwin; both systems have the same problem with using
3445 GUI facilities in a forked child. Also call syms_of_cygw32,
3446 syms_of_w32select in correct places.
3448 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3449 needs fork-then-exec for daemon launching.
3451 * font.h: Include frame.h.
3453 * image.c: Use the image library cache machinery only when we're
3454 compiling for native WINDOWSNT; Cygwin can use shared libraries
3455 like any other Unixlike system.
3457 * keyboard.c: Clarify a comment regarding the input loop.
3459 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3460 functions directly instead of trying to detect at runtime that our
3461 host operating system supports them. We make this change for two
3462 reasons: Cygwin lacks support for the multibyte character
3463 conversion functions used by the legacy menu code, and Cygwin
3464 never needs to rely on non-Unicode APIs.
3466 * unexw32.c (hinst): Declare extern.
3468 * w32.c: Change header order;
3469 (w32_strerror): Move to w32fns.c because we need it for
3470 non-WINDOWSNT builds.
3472 * w32.h: Add #error macro to make sure we don't include w32.h for
3473 Cygwin builds. Remove w32select declarations.
3475 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3476 w32fns.c. w32console.c is WINDOWSNT-only.
3478 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3479 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3481 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3482 (w32_major_version, w32_minor_version, w32_build_number)
3483 (os_subtype, sound_type): Define here
3484 (w32_defined_color): Make color parameter const for consistency
3485 with other _defined_color functions.
3486 (w32_createwindow): Unconditionally call w32_init_class instead of
3487 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3488 through the code is complex and unnecessary because class
3489 registration is practically free.
3490 (w32_name_of_message): New EMACSDEBUG-only function.
3491 (Fset_message_beep): Move here
3492 (Fx_open_connection): Require that the display name for Windows be
3493 "w32" for consistency, emacsclient disambiguation, and maybe, one
3494 day, multi-window-system support.
3495 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3496 Cygwin files for W32 GUI facilities, since these clearly don't
3497 expect Cygwin names.
3498 (_DebPrint): Define.
3499 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3500 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3501 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3502 (w32_last_error): Remove.
3504 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3506 * w32heap.c (syspage_mask): Declare here.
3507 (cache_system_info): Remove.
3509 * w32inevt.c (faked_key): Define globally, not statically.
3510 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3511 (w32_console_toggle_lock_key): Move to w32fns.c.
3513 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3515 * w32proc.c (_DebPrint): Move to w32fns.c.
3516 * w32select.c: Include string.h, stdio.h for Cygwin.
3517 * w32select.h: New File.
3519 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3521 (w32_message_fd): New variable. Under Cygwin, holds the file
3522 descriptor the system used to tell us about pending thread
3525 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3526 that prevented compilation under non-WINDOWSNT systems.
3528 (w32_initialize): Open /dev/windows and assign it to
3529 w32_message_fd. Provide w32 feature.
3531 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3532 (WM_EMACS_INPUT_READY): add.
3533 (prepend_msg, w32_message_fd): Declare globally.
3536 (keyboard_handle): Use only when WINDOWSNT.
3537 (notify_msg_ready): New function. Posts a message to the main
3538 thread's message queue under CYGWIN, which wakes up the main
3539 thread from select(2) by making the /dev/windows file descriptor
3540 ready. Under WINDOWSNT, it sets an event the same way the old
3543 (post, prepend_msg): Actually call notify_msg_ready instead of
3544 setting the input event directly.
3546 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3548 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3549 but it still has blocs in it, don't return it to the system,
3550 instead of aborting. (Bug#12402)
3552 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3554 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3556 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3557 MAC_OS_X_VERSION_10_6.
3558 (syms_of_nsterm): Remove comment about Panther and above for
3560 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3561 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3562 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3564 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3565 MAC_OS_X_VERSION_10_4.
3567 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3568 MAC_OS_X_VERSION_10_2.
3570 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3572 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3573 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3575 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3576 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3577 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3578 Remove ns_in_resize check.
3579 (ns_clear_frame_area): Remove resize handle code.
3581 * nsfns.m (ns_in_resize): Remove.
3582 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3583 Remove ns_in_resize check.
3585 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3587 Improve sys_siglist detection.
3588 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3589 defined as a macro, as is done in Solaris.
3590 (sys_siglist_entries): New macro.
3591 (save_strsignal): Use it.
3592 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3593 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3595 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3597 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3598 fullscreen/Fullscreen.
3600 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3601 tobar_height is new.
3603 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3604 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3605 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3606 (windowDidResize:): Check for correct window if old style fullscreen.
3607 Capitalize word in comment. Remove incorrect comment.
3608 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3609 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3610 error in drawing background.
3611 (toggleFullScreen:): Remove comment. Rearrange calls.
3612 Set toolbar values to zero, save old height in tobar_height.
3613 Restore tool bar height when leaving fullscreen.
3614 (canBecomeMainWindow): New function.
3616 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3618 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3620 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3622 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3624 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3625 that time stamps of directories could also be changed.
3626 Don't request the too broad GENERIC_WRITE, only the more restrictive
3627 FILE_WRITE_ATTRIBUTES access rights.
3629 * fileio.c (Fset_file_times): Special-case ignoring errors for
3630 directories only on MSDOS, not on MS-Windows.
3632 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3634 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3636 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3638 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3639 see whether CreateFile failed.
3641 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3643 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3644 to avoid similar races.
3645 * keyboard.c (pending_signals): Now bool, not int.
3647 Port timers to OpenBSD, plus check for timer failures.
3648 OpenBSD problem reported by Han Boetes.
3649 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3651 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3652 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3653 like OpenBSD, which has timer_settime but does not declare it.
3654 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3655 whether to use itimerspec-related primitives. All uses of
3656 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3658 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3660 * profiler.c (handle_profiler_signal): Fix a malloc race
3661 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3663 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3665 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3667 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3669 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3670 consistent with the change in return value of 'safe_strsignal'.
3672 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3674 Prefer plain 'static' to 'static inline' (Bug#12541).
3675 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3676 (bidi_set_sor_type, bidi_push_embedding_level)
3677 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3678 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3679 (bidi_cache_search, bidi_cache_ensure_space)
3680 (bidi_cache_iterator_state, bidi_cache_find)
3681 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3682 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3683 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3684 Now 'static', not 'static inline'.
3686 Count overruns when profiling; change units to ns.
3687 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3688 Give extra weight to samples after overruns, to attempt to count
3689 the time more accurately.
3690 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3691 the underlying primitives nominally do ns.
3692 (Fprofiler_cpu_start): Document the change. Mention that
3693 the sampling intervals are only approximate.
3695 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3697 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3699 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3700 case for the special 0 coding-system.
3702 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3703 (Fmake_overlay): Remove redundant tests.
3704 (fix_start_end_in_overlays): Remove redundant recentering.
3706 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3708 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3709 Update dependencies.
3711 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3713 Fix a malloc race condition involving strsignal.
3714 A signal can arrive in the middle of a malloc, and Emacs's signal
3715 handler can invoke strsignal, which can invoke malloc, which is
3716 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3717 Fix it by altering the signal handler so that it does not invoke
3719 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3720 * process.c (status_message): Use const pointer, in case strsignal
3721 is #defined to safe_strsignal.
3722 * sysdep.c (sys_siglist, init_signals): Always define and
3723 initialize a substitute sys_siglist if the system does not define
3724 one, even if HAVE_STRSIGNAL.
3725 (safe_strsignal): Rename from strsignal. Always define,
3726 using sys_siglist. Return a const pointer.
3727 * syssignal.h (safe_strsignal): New decl.
3728 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3730 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3732 * w32proc.c (timer_loop): Fix code that waits for timer
3733 expiration, to avoid high CPU usage.
3735 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3737 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3738 (sweep_weak_table): Remove redundant prototypes.
3740 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3742 * emacs.c: Move the inclusion of TERM_HEADER after including
3743 windows.h on WINDOWSNT. This avoids compilation problems with
3746 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3748 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3749 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3750 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3751 as the previous version used 'void *'.
3753 * ralloc.c (ROUNDUP): Fix last change.
3754 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3757 * w32proc.c <disable_itimers>: New static flag.
3758 (init_timers): Initialize it to zero, after creating the critical
3759 sections used by the timer threads.
3760 (term_timers): Set to 1 before deleting the critical sections.
3761 (getitimer, setitimer): If disable_itimers is non-zero, return an
3762 error indication without doing anything. Reported by Fabrice
3763 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3764 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3766 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3769 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3770 term_ntproc after all the other bookkeeping, to get timers working
3771 as long as possible.
3773 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3775 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3776 Suggested by Juri Linkov in
3777 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3779 Prefer plain 'static' to 'static inline' (Bug#12541).
3780 With static functions, modern compilers inline pretty well by
3781 themselves; advice from programmers often hurts as much as it helps.
3782 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3783 this change shrinks the text size of the Emacs executable by 1.1%
3784 without affecting CPU significantly in my benchmark.
3785 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3864 (bidi_copy_it): Do the whole copy with a single memcpy.
3865 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3867 Revert the FOLLOW-SYMLINKS change for file-attributes.
3868 Doing it right would require several changes to Tramp, and there's
3869 not enough time to get that tested before the freeze today.
3870 * dired.c (directory_files_internal, Ffile_attributes):
3873 * frame.c (x_report_frame_params): Port better to wider ints.

3912 * vm-limit.c (lim_data): Now size_t.
3913 (check_memory_limits): Adjust prototypes of real_morecore and
3914 __morecore to receive argument of type ptrdiff_t. Use size_t for

4067 Profiler improvements: more-accurate timers, overflow checks.
4068 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4069 signal.h, setjmp.h. Include systime.h instead.
4070 (saturated_add): New function.

4077 All uses changed to store the new value.
4078 (handle_profiler_signal): Rename from sigprof_handler_1,
4079 for consistency with other handlers. Do not check whether
4080 cpu_log is a hash-table if garbage collecting, since it
4081 doesn't matter in that case.

4083 for consistency with other handlers.
4084 (setup_cpu_timer): New function, with much of what used to be in
4085 Fprofiler_cpu_start. Check for out-of-range argument.
4086 Prefer timer_settime if available, and prefer
4087 thread cputime clocks, then process cputime clocks, then
4088 monotonic clocks, to the old realtime clock. Use make_timeval
4089 to round more-correctly when falling back to setitimer.
4090 (Fprofiler_cpu_start): Use it.
4091 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4092 Don't assume that passing NULL as the 2nd argument of setitimer
4093 is the same as passing a pointer to all-zero storage.
4094 Ignore SIGPROF afterwards.
4095 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4096 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4097 non-fatal signal handlers. Ignore SIGPROF on startup.
4098 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4099 in profiler.c, since sysdep.c now uses it.
4101 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4136 2012-09-27 Paul Eggert <eggert@cs.ucla.edu>
4138 Check more robustly for timer_settime.
4139 * Makefile.in (LIB_TIMER_TIME): New macro.

4156 * charset.c, charset.h (maybe_unify_char): Now static.
4157 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4158 Since this stuff is now private to charset.c, there's no need for
4159 a public macro and no need to inline by hand.

4190 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4192 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4194 Prefer POSIX timers if available.
4195 They avoid a race if the timer is too close to the current time.
4196 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4197 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4198 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4200 2012-09-25 Eli Zaretskii <eliz@gnu.org>

4203 CHAR_STRING_ADVANCE.
4204 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
4205 STRING_CHAR_ADVANCE.
4207 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4209 Move Vlibrary_cache to emacs.c and reset before dumping.
4211 * lisp.h (reset_image_types): Declare.
4212 [WINDOWSNT] (Vlibrary_cache): Declare.
4214 * image.c (reset_image_types): New function.
4216 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

4223 * w32.h (Vlibrary_cache): Do not declare.
4225 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4227 * w32proc.c (sys_signal): Handle all signals defined by the
4228 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4229 handlers for signals supported by Windows. Don't override
4230 term_ntproc as the handler for SIGABRT.
4231 (sigaction): Rewrite to call sys_signal instead of duplicating its
4233 (sys_kill): Improve commentary.
4235 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4236 consistency with a signature of a signal handler. All callers
4238 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4239 install term_ntproc as a signal handler for SIGABRT, as that
4240 should be done by the dumped Emacs.
4242 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4244 * w32select.c (term_w32select): Protect against repeated
4245 invocation by setting clipboard_owner to NULL after calling

4249 and term_ntproc to their modified signatures.
4251 * character.c (char_string, string_char): Remove calls to
4252 MAYBE_UNIFY_CHAR. See the discussion starting at
4253 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4256 2012-09-25 Chong Yidong <cyd@gnu.org>
4258 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4260 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4262 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4263 when encountering an unknown bytecode.
4265 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4267 image.c, indent.c: Use bool for booleans.
4268 * dispextern.h (struct image_type): Members valid_p, load, init
4269 now return bool, not int. All uses changed.
4270 * image.c: Omit unnecessary static decls.
4271 (x_create_bitmap_mask, x_build_heuristic_mask):
4272 Return void, not int, since callers don't care about the return value.

4301 Use bool for booleans.
4303 2012-09-24 Chong Yidong <cyd@gnu.org>
4305 * chartab.c (Fset_char_table_default): Obsolete function removed.
4307 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4309 Move pid_t related decls out of lisp.h.
4310 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4311 (interruptible_wait_for_termination):
4312 Move these decls from lisp.h to syswait.h, since they use pid_t.
4313 Needed on FreeBSD; see Herbert J. Skuhra in
4314 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4315 * callproc.c: Include syswait.h.

4332 * nsmenu.m (ns_update_menubar):
4333 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4334 * xfns.c (Fx_show_tip) [USE_GTK]:
4335 Use bool for boolean.
4336 * gtkutil.c (xg_update_frame_menubar):
4337 * xmenu.c (update_frame_menubar):
4338 Return void, not int, since caller ignores return value.
4339 * gtkutil.c (xg_change_toolbar_position):
4342 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4344 * makefile.w32-in (BLOCKINPUT_H): Remove.

4361 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4363 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4364 fatal_error_backtrace.
4366 * w32proc.c (sys_kill): Undo last change: don't do anything when
4367 invoked to deliver SIGABRT to our own process. This is now
4368 handled by emacs_raise.
4370 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4372 * w32term.c (w32_read_socket): Remove leftover reference to
4373 interrupt_input_pending.
4375 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4377 Do not use SA_NODEFER.
4378 Problem reported by Dani Moncayo in
4379 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4381 * sysdep.c (emacs_abort): Do not reset signal handler.
4382 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4383 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4384 wanted even on POSIXish hosts, and it doesn't work on Windows.
4386 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4388 * xterm.c (x_term_init): Call fixup_locale before and after calling
4389 gtk_init (Bug#12392).
4391 2012-09-23 Chong Yidong <cyd@gnu.org>
4393 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4394 Vdynamic_library_alist.
4396 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4397 (Fgnutls_available_p): Caller changed.
4399 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4400 (Flibxml_parse_xml_region): Likewise.
4402 * dispextern.h (struct image_type): Remove arg from init function.
4404 * image.c (Finit_image_library, lookup_image_type)
4405 (define_image_type): Remove now-unneeded second arg.
4406 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4407 (init_tiff_functions, init_gif_functions, init_svg_functions):
4408 Arglist and w32_delayed_load calling convention changed.
4409 (gs_type): Remove init_gs_functions; there is no such function.
4410 (valid_image_p, make_image): Fix caller to lookup_image_type.
4412 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4414 Simplify and avoid signal-handling races (Bug#12471).
4416 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4417 Avoid recursive loop if there's a fatal error in the function itself.
4418 * atimer.c (pending_atimers):
4419 * blockinput.h: Don't include "atimer.h"; no longer needed.
4420 (interrupt_input_pending): Remove. All uses removed.
4421 pending_signals now counts both atimers and ordinary interrupts.
4422 This is less racy than having three separate pending-signal flags.
4423 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4425 Rename from their upper-case counterparts BLOCK_INPUT,
4426 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4427 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4428 This makes it easier to access volatile variables more accurately.
4429 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4430 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4431 that's more reliable if the code is buggy and sets
4432 interrupt_input_blocked to a negative value. All uses changed.
4433 * atimer.c (deliver_alarm_signal):
4434 Remove. No need to deliver this to the parent; any thread can
4435 handle this signal now. All uses replaced by underlying handler.
4436 * atimer.c (turn_on_atimers):
4437 * dispnew.c (handle_window_change_signal):
4438 * emacs.c (handle_danger_signal):
4439 * keyboard.c (kbd_buffer_get_event):
4440 Don't reestablish signal handler; not needed with sigaction.
4441 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4443 Rework to avoid unnecessary accesses to volatile variables.
4444 (UNBLOCK_INPUT_TO): Now a function.
4445 (totally_unblock_input, unblock_input): New decls.
4446 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4447 (init_data): Remove. Necessary stuff now done in init_signal.
4448 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4449 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4450 (fatal_error_code): Remove; no longer needed.
4451 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4452 it doesn't always backtrace. All uses changed. No need to reset
4453 signal to default, since sigaction and/or die does that for us now.
4454 Use emacs_raise (FOO), not kill (getpid (), FOO).
4455 (main): Check more-accurately whether we're dumping.
4456 Move fatal-error setup to sysdep.c
4457 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4458 * gtkutil.c (xg_get_file_name, xg_get_font):
4459 Remove no-longer-needed signal-mask manipulation.
4460 * keyboard.c, process.c (POLL_FOR_INPUT):
4461 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4462 * keyboard.c (read_avail_input): Remove.
4463 All uses replaced by gobble_input.
4464 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4465 (kbd_buffer_store_event_hold, gobble_input):
4466 (record_asynch_buffer_change) [USABLE_SIGIO]:
4467 (store_user_signal_events):
4468 No need to mess with signal mask.
4469 (gobble_input): If blocking input and there are terminals, simply
4470 set pending_signals to 1 and return. All hooks changed to not
4471 worry about whether input is blocked.
4472 (process_pending_signals): Clear pending_signals before processing
4473 them, in case a signal comes in while we're processing.
4474 By convention callers now test pending_signals before calling us.
4475 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4476 New functions, to support changes to blockinput.h.
4477 (handle_input_available_signal): Now extern.
4478 (reinvoke_input_signal): Remove. All uses replaced by
4480 (quit_count): Now volatile, since a signal handler uses it.
4481 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4482 All callers changed. Block SIGINT only if not already blocked.
4483 Clear sigmask reliably, even if Fsignal returns, which it can.
4484 Omit unnecessary accesses to volatile var.
4485 (quit_throw_to_read_char): No need to restore sigmask.
4486 * keyboard.c (gobble_input, handle_user_signal):
4487 * process.c (wait_reading_process_output):
4488 Call signal-handling code rather than killing ourselves.
4489 * lisp.h: Include <float.h>, for...
4490 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4491 (pending_signals): Now volatile.
4492 (syms_of_data): Now const if IEEE floating point.
4493 (handle_input_available_signal) [USABLE_SIGIO]:
4494 (terminate_due_to_signal, record_child_status_change): New decls.
4495 * process.c (create_process): Avoid disaster if memory is exhausted
4496 while we're processing a vfork, by tightening the critical section
4498 (send_process_frame, process_sent_to, handle_pipe_signal)
4499 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4501 (send_process): No need for setjmp/longjmp any more, since the
4502 SIGPIPE stuff is now gone. Instead, report an error if errno
4504 (record_child_status_change): Now extern. PID and W are now args.
4505 Return void, not bool. All callers changed.
4506 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4507 Remove. All uses removed. This bug should be fixed now in a
4509 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4510 and record the child status change directly. This avoids the
4511 need to futz with the signal mask.
4512 (process_fatal_action): Move here from emacs.c.
4513 (emacs_sigaction_flags): New function, containing
4514 much of what used to be in emacs_sigaction_init.
4515 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4516 caught by emacs, to make races less likely.
4517 (deliver_process_signal): Rename from handle_on_main_thread.
4519 (BACKTRACE_LIMIT_MAX): Now at top level.
4520 (thread_backtrace_buffer, threadback_backtrace_pointers):
4522 (deliver_thread_signal, deliver_fatal_thread_signal):
4523 New functions, for more-accurate delivery of thread-specific signals.
4524 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4525 (deliver_arith_signal): Handle in this thread, not
4526 in the main thread, since it's triggered by this thread.
4527 (maybe_fatal_sig): New function.
4528 (init_signals): New arg DUMPING so that we can be more accurate
4529 about whether we're dumping. Caller changed.
4530 Treat thread-specific signals differently from process-general signals.
4531 Block all signals while handling fatal error; that's safer.
4532 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4534 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4535 Ignore SIGPIPE unless batch.
4536 (emacs_backtrace): Output backtrace for the appropriate thread,
4537 which is not necessarily the main thread.
4538 * syssignal.h: Include <stdbool.h>.
4539 (emacs_raise): New macro.
4540 * xterm.c (x_connection_signal): Remove; no longer needed
4541 now that we use sigaction.
4542 (x_connection_closed): No need to mess with sigmask now.
4543 (x_initialize): No need to reset SIGPIPE handler here, since
4544 init_signals does this for us now.
4546 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4548 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4549 background rect may be larger (Bug#12245).
4551 2012-09-23 Chong Yidong <cyd@gnu.org>
4553 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4555 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4557 * .gdbinit: Just stop at fatal_error_backtrace.
4558 See Stefan Monnier's request in
4559 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4560 Remove no-longer-used query of system type.
4562 2012-09-22 Chong Yidong <cyd@gnu.org>
4564 * search.c (Freplace_match): Doc fix (Bug#12325).
4566 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4568 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4569 (Fline_end_position): Doc fix.
4571 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4573 2012-09-22 Chong Yidong <cyd@gnu.org>
4575 * dispextern.h (struct image_type): Add new slot, storing a type
4576 initialization function.
4578 * image.c (define_image_type): Call the image initializer function
4579 if it is defined. Arguments and return value changed.
4580 (valid_image_p, make_image): Callers changed.
4581 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4582 (gif_type, imagemagick_type, svg_type, gs_type):
4583 Add initialization functions.
4584 (Finit_image_library): Call lookup_image_type.
4585 (CHECK_LIB_AVAILABLE): Macro deleted.
4586 (lookup_image_type): Call define_image_type here, rather than via
4587 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4588 (syms_of_image): Move define_image_type calls for xbm_type and
4589 pbm_type to lookup_image_type.

4593 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4594 'idle_timers' from here ...
4595 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4596 lists, to avoid infloops when the timer does something stupid,
4597 like reinvoke itself with the same or smaller time-out.
4600 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4602 * window.c (Fsplit_window_internal): Handle only Qt value of
4603 Vwindow_combination_limit separately.
4604 (Qtemp_buffer_resize): New symbol.
4605 (Vwindow_combination_limit): New default value.
4608 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4610 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4611 the new overlay string. (Bug#10159)
4613 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4615 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4616 or that fprintf is async-signal-safe. POSIX doesn't require
4619 2012-09-22 Chong Yidong <cyd@gnu.org>
4621 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4624 2012-09-22 Kenichi Handa <handa@gnu.org>
4626 * composite.c (composition_reseat_it): Handle the case that a
4627 grapheme cluster is not covered by a single font (Bug#12352).
4629 2012-09-21 Chong Yidong <cyd@gnu.org>
4631 * image.c (define_image_type): Avoid adding duplicate types to
4632 image_types (Bug#12463). Suggested by Jörg Walter.
4634 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4636 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4637 (print_load_command_name): Add case LC_DATA_IN_CODE.
4638 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4640 2012-09-21 Glenn Morris <rgm@gnu.org>
4642 * eval.c (Frun_hook_with_args_until_success)
4643 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4645 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4647 * fileio.c (Ffile_selinux_context): Only call freecon when
4648 lgetfilecon succeeded.
4649 (Fset_file_selinux_context): Likewise. (Bug#12444)
4651 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4653 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4654 reordering, locate the cursor by calling set_cursor_from_row; if
4655 that fails, clear the desired glyph matrix before returning a
4656 failure indication to the caller. Fixes leaving garbled display
4657 when fast scrolling with a down-key. (Bug#12403)
4658 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4659 scrolling through multibyte text.
4661 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4663 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4664 calling mark_vectorlike since that's the one that marks the window.
4665 (mark_discard_killed_buffers): Mark the final cdr.
4666 * window.h (struct window): Move prev/next_buffers to the
4667 non-standard fields.
4668 * window.c (make_window): Initialize prev/next_buffers manually.
4670 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4672 Omit unused arg EXPECTED from socket hooks.
4673 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4674 * nsterm.m (ns_term_init):
4675 * termhooks.h (struct terminal.read_socket_hook):
4676 * w32inevt.c (w32_console_read_socket):
4677 * w32term.c (w32_read_socket):
4678 * xterm.c (XTread_socket):
4679 Omit unused arg EXPECTED. All callers changed.
4680 (store_user_signal_events): Return void, not int, since callers no
4681 longer care about the return value. All uses changed.
4683 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4685 * w32gui.h (XParseGeometry): Do not declare.
4687 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4689 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4690 Ignore 'expected'. See Eli Zaretskii in
4691 <http://bugs.gnu.org/12471#8> (last line).
4693 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4694 (XParseGeometry): Now static. Substitute extremal values for
4695 values that are out of range.
4697 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4699 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4701 * nsfns.m (XParseGeometry): Remove.
4702 (Fx_create_frame): Call x_set_offset to correctly interpret
4703 top_pos in geometry.
4705 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4706 (Fx_parse_geometry): If there is a space in string, call
4707 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4709 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4711 * search.c (scan_buffer): Use character positions in calls to
4712 region_cache_forward and region_cache_backward, not byte
4713 positions. (Bug#12196)
4715 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4716 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4718 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4719 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4720 emacs_blocked_malloc, now deleted.
4722 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4724 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4725 The workaround was for improving performance on Solaris 2.4, but
4726 is getting in the way now. Emacs will still work if someone is
4727 still running Solaris 2.4 in a museum somewhere; Sun dropped
4728 support for Solaris 2.4 in 2003.
4729 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4730 * process.c (create_process) [HAVE_WORKING_VFORK]:
4731 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4732 since Emacs no longer uses vfork on that platform.
4734 2012-09-17 Glenn Morris <rgm@gnu.org>
4736 * emacs.c: Use COPYRIGHT.
4738 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4740 Remove configure's --without-sync-input option (Bug#12450).
4741 When auditing signal-handling in preparation for cleaning it up,
4742 I found that SYNC_INPUT has race conditions and would be a real
4743 pain to fix. Since it's an undocumented and deprecated
4744 configure-time option, now seems like a good time to remove it.
4745 Also see <http://bugs.gnu.org/11080#16>.
4746 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4747 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4748 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4749 (malloc_hysteresis):
4750 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4751 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4752 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4753 (dont_register_blocks, bytes_used_when_reconsidered)
4754 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4755 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4756 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4757 Remove. All uses removed.
4758 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4759 implementation, one that depends on whether the new macro
4760 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4762 * atimer.c (run_timers, handle_alarm_signal):
4763 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4764 (handle_async_input, process_pending_signals)
4765 (handle_input_available_signal, init_keyboard):
4766 * nsterm.m (ns_read_socket):
4767 * process.c (wait_reading_process_output):
4768 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4769 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4771 * xterm.c (XTread_socket):
4773 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4774 * eval.c (handling_signal): Remove. All uses removed.
4775 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4776 All uses replaced with the SYNC_INPUT version.
4777 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4779 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4782 * font.c (Ffont_shape_gstring): Remove unused local.
4784 2012-09-16 Glenn Morris <rgm@gnu.org>
4786 * Makefile.in (clean): No longer run nextstep's clean.
4788 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4790 (ns-app): Move here from ns.mk, and simplify.
4791 (clean): Simplify nextstep entry.
4792 * ns.mk: Remove file.
4794 2012-09-17 Kenichi Handa <handa@gnu.org>
4796 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4797 not covert the last few charactes.
4799 2012-09-16 Kenichi Handa <handa@gnu.org>
4801 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4802 here, but just check the validity of glyphs in the glyph-string.
4804 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4806 * window.c (Fwindow_parameter, Fset_window_parameter):
4807 Accept any window as argument (Bug#12452).
4809 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4811 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4812 to ns_term_init to avoid memory leak.
4814 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4815 explicit retain/release.
4816 (ns_term_init): Only allow one display. Initialize outerpool and
4819 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4821 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4822 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4823 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4824 the Microsoft problem in a different way, by altering ../nt/config.nt.
4826 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4841 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4842 by lisp.h. This completes removal of setjmp.h inclusion
4843 erroneously announced in the previous commit. (Bug#12446)
4845 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4848 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4849 not defined as a macro. The latter happens on MS-Windows.
4852 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4854 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4855 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4856 Some instances of '#include <setjmp.h>' removed, if the
4857 only reason for the instance was because "lisp.h" was included.
4858 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4859 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4860 and _longjmp with the new symbols. Emacs already uses _setjmp if
4861 available, so this change affects only POSIXish hosts that have
4862 sigsetjmp but not _setjmp, such as some versions of Solaris and
4863 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4864 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4865 (png_load_body) [HAVE_PNG]:
4866 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4867 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4868 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4869 since PNG requires jmp_buf. This is the only exception to the
4870 general rule that we now use sys_setjmp and sys_longjmp.
4871 This exception is OK since this code does not change the signal
4872 mask or longjmp out of a signal handler.
4874 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4876 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4877 Include "syssignal.h", for 'main_thread'.
4879 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4881 Avoid out-of-range marker position (Bug#12426).
4882 * insdel.c (replace_range, replace_range_2):
4883 Adjust markers before overlays, as suggested by comments.
4884 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4885 Remove redundant check before calling offset_intervals.
4887 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4889 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4890 current buffer (Bug#12387).
4892 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4894 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4896 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4898 Use a more backwards-compatible timer format (Bug#12430).
4899 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4900 vector element, not from the 4th, since PSECS is now at the end.
4901 (Fcurrent_idle_time): Doc fix.
4903 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4905 Function to mark objects and remove killed buffers at once.
4906 * alloc.c (discard_killed_buffers): Rename to ...
4907 (mark_discard_killed buffers) ... new name. Add marking
4908 of remaining objects. Fix comment. Adjust users.
4909 (mark_object): Do not touch frame buffer lists here.
4910 * frame.c (delete_frame): Reset frame buffer lists here.
4912 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4914 Better workaround for GNOME bug when --enable-gcc-warnings.
4915 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4916 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4917 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4919 Simplify SIGIO usage (Bug#12408).
4920 The code that dealt with SIGIO was crufty and confusing, e.g., it
4921 played tricks like "#undef SIGIO" but these tricks were not used
4922 consistently. Simplify mostly by not #undeffing standard symbols,
4923 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4924 or not as we please) rather than "defined SIGIO" (standard symbol
4925 that we probably shouldn't #undef).
4926 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4927 Modules that need it can include it.
4928 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4929 * dispextern.h (ignore_sigio): New decl.
4930 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4931 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4932 * emacs.c (shut_down_emacs):
4933 * keyboard.c (kbd_buffer_store_event_hold):
4934 Use ignore_sigio rather than invoking 'signal' directly.
4935 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4937 (FIONREAD, SIGIO): Do not #undef.
4938 (tty_read_avail_input): Use #error rather than a syntax error.
4939 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4940 for I_PIPE, used by SETUP_SLAVE_PTY.
4941 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4942 * sysdep.c (croak): Remove; no longer needed. This bit of
4943 temporary code, with Fred N. Fish's comment that it's temporary,
4944 has been in Emacs since at least 1992!
4945 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4946 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4947 * syssignal.h (croak): Remove decl.
4948 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4949 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4950 now that we're termios-only.
4951 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4952 * term.c (dissociate_if_controlling_tty): Use #error rather than
4955 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4956 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4957 to work around GNOME bug 683906.
4958 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4959 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4960 This works around GCC bug 54561.
4962 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4964 More fixes for 'volatile' and setjmp/longjmp.
4965 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4966 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4967 (png_load_body) [HAVE_PNG]:
4968 (jpeg_load_body) [HAVE_JPEG]:
4969 New function, with most of the old parent function's body.
4970 (png_load) [HAVE_PNG]:
4971 (jpeg_load) [HAVE_JPEG]:
4972 Invoke the new function, to avoid longjmp munging our locals.
4973 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4974 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4975 longjmp is passed 2, as the C standard doesn't guarantee this.
4976 Instead, store the failure code into mgr->failure_code.
4978 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4980 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4981 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4982 (syms_of_keyboard): Remove support for unread-command-char.
4984 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4986 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4987 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4988 violation. (Bug#12426)
4990 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4992 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4994 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4996 * eval.c: Add `inhibit-debugger'.
4997 (Qinhibit_debugger): New symbol.
4998 (call_debugger): Bind it instead of Qdebug_on_error.
4999 (maybe_call_debugger): Test Vinhibit_debugger.
5000 (syms_of_eval): Define inhibit-debugger.
5001 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5002 (syms_of_xdisp): Remove inhibit-debug-on-message.
5004 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5006 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5007 If a nonvolatile local variable is written before a _longjmp to
5008 the frame containing the variable, and is read after the _longjmp,
5009 the value read is indeterminate. Some local variables of type
5010 'struct handler' and 'struct catchtag' are used in this way, so
5011 mark each of their slots as volatile if the slot can be set before
5012 _longjmp and read afterwards.
5013 * lisp.h (struct handler): var and chosen_clause are now volatile.
5014 (struct catchtag): val, next, and pdlcount are now volatile.
5016 * bidi.c (bidi_push_it, bidi_pop_it):
5017 * fns.c (copy_hash_table):
5018 * image.c (define_image_type):
5019 * keyboard.c (kbd_buffer_store_event_hold):
5020 * process.c (Fprocess_send_eof):
5021 * xfaces.c (x_create_gc) [HAVE_NS]:
5022 * xgselect.c (xg_select):
5023 Prefer assignment to memcpy when either will do.
5025 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5026 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5027 time an item is removed. No need to mark this function 'inline';
5028 the compiler knows better than we do.
5030 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5032 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5033 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5034 to change_frame_size (Bug#12388).
5035 (windowDidResize:): Pass YES to updateFrameSize.
5037 * nsterm.h: Add delay parameter to updateFrameSize.
5039 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5041 Discard killed buffers from deleted window and frame objects.
5042 This reduces an amount of references to killed buffers and
5043 helps GC to reclaim them faster.
5044 * alloc.c (discard_killed_buffers): New function.
5045 (mark_object): Use it for deleted windows and frames.
5046 (mark_object): If symbol's value is set up for a killed buffer
5047 or deleted frame, restore its global binding.
5048 * data.c (swap_in_global_binding): Add GC notice.
5049 (swap_in_symval_forwarding): Use convenient set_blv_where.
5050 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5051 * window.h: ... to here.
5053 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5055 Convenient macro to check whether the buffer is live.
5056 * buffer.h (BUFFER_LIVE_P): New macro.
5057 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5058 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5060 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5062 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5063 composition cases (Bug#12364).
5065 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5066 overhang of succeeding glyphs overlapping box cursor.
5068 * w32term.c (x_draw_glyph_string): Likewise.
5070 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5072 Simplify, document, and port floating-point (Bug#12381).
5073 The porting part of this patch fixes bugs on non-IEEE platforms
5074 with frexp, ldexp, logb.
5075 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5077 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5078 support, by removing commented-out code and briefly listing the
5079 C89 functions excluded. The commented-out stuff was confusing
5080 maintenance, e.g., we thought we needed cbrt but it was commented out.
5081 (logb): Remove decl; no longer needed.
5082 (isfinite): New macro, if not already supplied.
5083 (isnan): Don't replace any existing macro.
5084 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5085 are present on all C89 platforms.
5086 (Ffrexp): Do not special-case zero, as frexp does the right thing
5088 (Flogb): Do not use logb, as it doesn't have the desired meaning
5089 on hosts that use non-base-2 floating point. Instead, stick with
5090 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5091 frexp, to avoid getting an unspecified result.
5093 * xdisp.c (Qinhibit_debug_on_message): Now static.
5095 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5097 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5098 NSBezierPath (Bug#12131).
5100 2012-09-10 Chong Yidong <cyd@gnu.org>
5102 * fns.c (Fdelq, Fdelete): Doc fix.
5104 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5106 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5107 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5109 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5111 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5112 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5115 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5117 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5118 left fringe if the window has a left margin. This avoids leaving
5119 traces of the cursor because its leftmost pixel is not drawn over.
5121 * dispnew.c (update_window_line): When the left margin area of a
5122 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5123 that screen line. (Bug#12277)
5125 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5127 Assume C89 or later for math functions (Bug#12381).
5128 This simplifies the code, and makes it a bit smaller and faster,
5129 and (most important) makes it easier to clean up signal handling
5130 since we can stop worring about floating-point exceptions in
5131 library code. That was a problem before C89, but the problem
5132 went away many years ago on all practical Emacs targets.
5133 * data.c, image.c, lread.c, print.c:
5134 Don't include <math.h>; no longer needed.
5135 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5136 might be autoconfigured, as that never happens.
5138 * doprnt.c (DBL_MAX_10_EXP):
5139 * print.c (DBL_DIG):
5140 Remove. C89 or later always defines these.
5141 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5142 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5143 (arith_error, domain_error, domain_error2):
5144 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5145 no longer needed -- we simply return what C returns. All uses removed.
5146 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5148 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5149 Remove. All uses expanded, as these macros are no longer used
5150 more than once and are now more trouble than they're worth.
5151 (Ftan): Use tan, not sin / cos.
5152 (Flogb): Assume C89 frexp.
5153 (fmod_float): Assume C89 fmod.
5154 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5155 (init_floatfns): Remove. All uses removed.
5157 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5159 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5160 compositeToPoint for OSX < 10.6 (Bug#12390).
5162 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5164 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5165 This produces more-accurate results.
5167 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5169 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5170 changes (Bug#12088).
5172 2012-09-08 Chong Yidong <cyd@gnu.org>
5174 * syntax.c (Fstring_to_syntax): Doc fix.
5176 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5178 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5179 in the internal border.
5180 (x_set_window_size): Remove static variables and their usage.
5181 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5182 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5183 Remove fringe/internal border adjustment (Bug#11052).
5184 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5185 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5186 (ns_fix_rect_ibw): Remove.
5187 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5188 (ns_dumpglyphs_box_or_relief): Ditto.
5189 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5191 (ns_dumpglyphs_image): Ditto.
5192 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5194 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5195 their usage. Add fringe_extended_p and its use as in other terms.
5196 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5197 scroll bar was removed.
5198 (updateFrameSize): New function.
5199 (windowDidResize): Move code to updateFrameSize and call it.
5201 * nsterm.h (EmacsView): Add updateFrameSize.
5203 2012-09-07 Chong Yidong <cyd@gnu.org>
5205 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5207 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5209 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5211 More signal-handler cleanup (Bug#12327).
5212 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5213 Problem introduced when merging patches. Noted by Eli Zaretskii in
5214 <http://bugs.gnu.org/12327#67>.
5215 * floatfns.c: Comment fix.
5216 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5217 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5218 and anyway the declaration is harmless even if SIGDANGER is not defined.
5219 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5220 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5221 source files not surprisingly expected syssignal.h to define, or
5222 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5223 Include <sys/ioctl.h>, for FIONREAD.
5224 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5225 This eliminates a problem whereby other files mysteriously had
5226 to include "syssignal.h" before including "systty.h" if they
5227 wanted to use "#ifdef SIGIO".
5229 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5231 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5233 * w32.c (sigemptyset): Empty the set.
5234 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5236 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5238 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5240 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5241 (mark_object): Likewise for frame objects.
5243 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5245 * syssignal.h (handle_on_main_thread): Always declare,
5246 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5247 This ports to platforms without HAVE_PTHREAD.
5249 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5251 Signal-handler cleanup (Bug#12327).
5252 Emacs's signal handlers were written in the old 4.2BSD style with
5253 sigblock and sigmask and so forth, and this led to some
5254 inefficiencies and confusion. Rewrite these to use
5255 pthread_sigmask etc. without copying signal sets around. Also,
5256 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5257 'signal', and instead use functions that do not attempt to take
5258 over the system name space. This patch causes Emacs's text
5259 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5260 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5261 Do not include <signal.h> or "syssignal.h", as these
5262 modules do not use signals.
5263 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5264 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5265 Do not include <signal.h>, as "syssignal.h" does that for us now.
5266 * atimer.c (sigmask_atimers): New function.
5267 (block_atimers, unblock_atimers): New functions,
5268 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5270 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5271 no longer needed here.
5272 * emacs.c (main): Inspect existing signal handler with sigaction,
5273 so that there's no need to block and unblock SIGHUP.
5274 * sysdep.c (struct save_signal): New member 'action', replacing
5275 old member 'handler'.
5276 (save_signal_handlers, restore_signal_handlers):
5277 Use sigaction instead of 'signal' to save and restore.
5278 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5279 New function. All users of 'signal' modified to use set_sighandler
5280 if they're writeonly, and to use sys_signal if they're read+write.
5281 (emacs_sigaction_init, forwarded_signal): New functions.
5282 (sys_signal): Remove. All uses replaced by calls to sigaction
5283 and emacs_sigaction_init, or by direct calls to 'signal'.
5284 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5285 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5286 all uses replaced by pthread_sigmask etc. calls.
5287 * syssignal.h: Include <signal.h>.
5288 (emacs_sigaction_init, forwarded_signal): New decls.
5289 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5290 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5291 (sigmask, sys_sigmask): Remove; no longer needed.
5292 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5293 (sigblock, sigunblock, sigfree):
5294 (sigsetmask) [!defined sigsetmask]:
5295 Remove. All uses replaced by pthread_sigmask.
5296 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5297 no longer need to be replaced, and its typical old uses
5298 are now done via emacs_sigaction_init and sigaction.
5299 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5300 (sys_sigdel): Remove; unused.
5301 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5303 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5305 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5306 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5308 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5310 Explicitly mark buffer_defaults and buffer_local_symbols.
5311 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5312 mark_local_symbols here.
5313 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5314 since special buffers aren't marked here any more.
5315 (allocate_buffer): Chain new buffer with all_buffers here...
5316 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5318 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5319 (syms_of_buffer): Remove staticpro of the above.
5320 (init_buffer_once): Set names for buffer_defaults and
5321 buffer_local_symbols.
5323 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5325 Use bool for booleans in font-related modules.
5326 * font.c (font_intern_prop, font_style_to_value)
5327 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5328 (generate_otf_features, font_check_otf_features, font_check_otf)
5329 (font_match_p, font_list_entities, font_at):
5330 * fontset.c (fontset_id_valid_p, reorder_font_vector
5331 (fontset_find_font, Fset_fontset_font)
5332 (face_suitable_for_char_p) [0]:
5333 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5334 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5335 (m17n_flt_initialized, ftfont_shape_by_flt):
5336 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5337 * nsfont.m (nsfont_draw):
5338 * w32font.c (w32font_draw):
5339 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5340 Use bool for booleans.
5341 * font.h: Adjust to above API changes.
5342 (struct font, struct font_driver, struct font_driver_list):
5343 Use bool for booleans.
5344 (struct font): Remove useless member encoding_type.
5346 * fontset.c, xftfont.c: Omit unnecessary static decls.
5348 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5350 * alloc.c (mark_object): Revert window marking code
5351 since it's unsafe for the Fset_window_configuration.
5353 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5355 Fix race conditions with signal handlers and errno (Bug#12327).
5356 Be more systematic about preserving errno whenever a signal
5357 handler returns, even if it's not in the main thread. Do this by
5358 renaming signal handlers to distinguish between signal delivery
5359 and signal handling. All uses changed.
5360 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5361 * data.c (deliver_arith_signal): Rename from arith_error.
5362 * dispnew.c (deliver_window_change_signal): Rename from
5363 window_change_signal.
5364 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5365 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5366 * keyboard.c (deliver_input_available_signal): Rename from
5367 input_available_signal.
5368 (deliver_user_signal): Rename from handle_user_signal.
5369 (deliver_interrupt_signal): Rename from interrupt_signal.
5370 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5371 (deliver_child_signal): Rename from sigchld_handler.
5372 * atimer.c (handle_alarm_signal):
5373 * data.c (handle_arith_signal):
5374 * dispnew.c (handle_window_change_signal):
5375 * emacs.c (handle_fatal_signal, handle_danger_signal):
5376 * keyboard.c (handle_input_available_signal):
5377 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5378 * process.c (handle_pipe_signal, handle_child_signal):
5379 New functions, with the actual signal-handling code taken from the
5380 original respective signal handlers, sans the sporadic attempts to
5381 preserve errno, since that's now done by handle_on_main_thread.
5382 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5383 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5384 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5386 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5387 Move initialization of main_thread to sysdep.c's init_signals.
5388 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5389 our usage, and simplifies the mainline code.
5390 (record_child_status_change): New static function, as a helper
5391 for handle_child_signal, and with most of the old child handler's
5393 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5394 (handle_child_signal): Use the above.
5395 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5396 Moved here from emacs.c.
5397 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5398 code moved here from emacs.c's main function.
5399 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5400 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5401 This lets callers save and restore errno properly.
5403 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5405 Remove redundant or unused things here and there.
5406 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5407 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5408 * editfns.c (Fcompare_buffer_substrings): Likewise.
5409 * frame.h (struct terminal, struct font_driver_list):
5410 Remove redundant declarations.
5411 * window.h (Qleft, Qright): Likewise.
5413 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5415 Do not mark objects from deleted buffers, windows and frames.
5416 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5417 (mark_object): Likewise for windows and frames.
5419 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5421 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5422 buffer_defaults and buffer_local_symbols as valid objects.
5423 Return special value to denote them.
5425 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5427 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5428 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5429 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5430 (file_name_absolute_p, Fsubstitute_in_file_name):
5431 (check_executable, check_writable, Ffile_accessible_directory_p)

5433 (Finsert_file_contents, choose_write_coding_system)
5434 (Fwrite_region, build_annotations, a_write, e_write)
5436 * filelock.c (boot_time_initialized, get_boot_time)
5437 (get_boot_time_1, lock_file_1, within_one_second):
5438 * floatfns.c (in_float):
5439 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5440 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5441 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5442 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5443 * window.c (compare_window_configurations):
5444 Use bool for booleans.
5445 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5446 (Fdefault_file_modes): Now mode_t, not int, for modes.
5447 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5448 (internal_delete_file): Now returns void, not a (boolean) int,
5449 since nobody was looking at the return value.
5450 * lisp.h, window.h: Adjust to above API changes.
5452 * xdisp.c (set_message): Simplify and reindent last change.
5454 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5456 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5458 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5460 * eval.c (call_debugger): Make the function non-static so that we
5461 can call it from set_message.
5463 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5464 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5466 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5468 Give more-useful info on a fatal error (Bug#12328).
5469 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5470 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5471 of doing the work ourselves.
5472 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5473 do most of the work.
5474 (fatal_error_backtrace): New function, taken from the guts
5475 of the old fatal_error_signal, but with a new option to output
5477 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5478 info about the signal than just its number.
5479 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5480 * sysdep.c: Include <execinfo.h>
5481 (emacs_backtrace): New function, taken partly from the previous
5482 code of the 'die' function.
5483 (emacs_abort): Call fatal_error_backtrace rather than abort.
5485 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5487 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5488 eager (load-time) macro-expansion.
5489 * lisp.mk (lisp): Add macroexp.
5491 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5493 Simplify redefinition of 'abort' (Bug#12316).
5494 Do not try to redefine the 'abort' function. Instead, redo
5495 the code so that it calls 'emacs_abort' rather than 'abort'.
5496 This removes the need for the NO_ABORT configure-time macro
5497 and makes it easier to change the abort code to do a backtrace.
5498 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5499 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5500 Remove; sysdep.c's emacs_abort now takes its place.
5501 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5502 'abort' changed to use 'emacs_abort'.
5503 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5504 (abort) [!defined abort]: Rename to ...
5505 (emacs_abort): ... new name.
5506 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5507 the place of the old 'abort' in emacs.c.
5508 * w32.c, w32fns.c (abort): Do not #undef.
5509 * w32.c (emacs_abort): Rename from w32_abort.
5511 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5513 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5514 offsets[j].dv, since the y axis of the screen coordinates points
5515 down, while the y axis of the font definition coordinates points
5516 up. This fixes display of Arabic diacritics such as KASRA and
5517 KASRATAN. (Bug#11860)
5519 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5521 Be more systematic about _setjmp vs setjmp.
5522 * alloc.c (test_setjmp, mark_stack):
5523 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5524 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5525 (png_load, my_error_exit, jpeg_load):
5526 * process.c (send_process_trap, send_process):
5527 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5528 The underscored versions are up to 30x faster on some hosts.
5529 Formerly, the code used setjmp+longjmp sometimes and
5530 _setjmp+_longjmp at other times, with no particular reason to
5531 prefer setjmp+longjmp.
5533 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5535 Fix minor problem found by static checking.
5536 * buffer.c (Fdelete_all_overlays): Return nil.
5538 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5540 * buffer.c (Fdelete_all_overlays): New function.
5542 2012-09-03 Chong Yidong <cyd@gnu.org>

5562 EXCLUDE_SUBRS_P. All callers changed.
5563 * dispextern.h, lisp.h: Reflect above API changes.
5564 * firstfile.c (dummy): Use the address of 'main', whose signature
5565 won't change, instead of the address of 'initialize', whose
5566 signature just changed from int to bool.
5567 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5568 * msdos.c (fatal_error_in_progress): ... from here.
5569 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5571 (redisplay_internal, unwind_redisplay): Simply clear
5572 REDISPLAYING_P when unwinding, instead of saving its previous,
5573 always-false value and then restoring it.
5575 Clean up some extern decls.
5576 Mostly, this hoists extern decls out of .c files and into .h files.
5577 That way, we're more likely to catch errors if the interfaces change.
5578 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5579 declare xg_mark_data.
5580 * dispextern.h (x_frame_parm_handlers):
5582 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

5598 * xfont.c (x_clear_errors):
5599 * xterm.c (x_frame_parm_handlers):
5600 Remove now-redundant extern decls.
5601 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5602 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5604 * xfaces.c: Remove unnecessary static decls.
5605 * xterm.c (updating_frame): Remove decl of nonexistent object.
5607 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5608 when building globals.h, as the objects that are not built on
5609 this host are not needed to compile C files on this host.
5611 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5613 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5651 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5653 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5661 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5663 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5664 more than one grapheme cluster passed to the shaper: compute the
5665 offset adjustment values separately for each cluster. (Bug#11860)
5667 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5668 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5669 about implicit conversions from integer to pointer.
5671 2012-09-01 Daniel Colascione <dancol@dancol.org>
5673 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5674 system used too early.
5676 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5678 Better seed support for (random).

5727 window system declarations.
5729 * frame.h: Move common functions here: set_frame_menubar,
5730 x_set_window_size, x_sync, x_get_focus_frame,
5731 x_set_mouse_position, x_set_mouse_pixel_position,
5732 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5756 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5758 Remove mark_ttys function and fix tty_display_info initialization.
5759 * lisp.h (mark_ttys): Remove prototype.
5760 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5761 to mark_ttys because all possible values of 'top_frame' slot are
5762 the frames which are reachable from Vframe_list.
5763 * term.c (mark_ttys): Remove.
5764 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5766 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

5793 * lread.c (init_lread): For out-of-tree builds, only add the
5794 source directory's site-lisp dir to the load-path if it exists,
5795 consistent with in-tree builds. (Bug#12302)
5797 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

5816 Handle click on close button as quit.
5818 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5819 Add window_closed and button_values. Add void as return value for
5820 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5821 Add process_dialog as new member.
5823 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5825 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5933 * composite.h, lisp.h: Reflect above API changes.
5935 * cmds.c, coding.c: Use bool for booleans.
5936 * cmds.c (move_point, Fself_insert_command):
5937 * coding.h (struct composition status, struct coding_system):
5938 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
5939 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
5940 (emacs_mule_char, decode_coding_emacs_mule)

5953 (detect_coding_system, char_encodable_p)
5954 (Funencodable_char_position, code_convert_region)
5955 (code_convert_string, code_convert_string_norecord)
5956 (Fset_coding_system_priority):
5957 * fileio.c (Finsert_file_contents):
5958 Use bool for booleans.
5959 * coding.h, lisp.h: Reflect above API changes.
5960 * coding.c: Remove unnecessary static function decls.
5961 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5962 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5963 not a boolean 'int', since callers never look at the return value.
5964 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5965 * coding.h (decoding_buffer_size, encoding_buffer_size)
5966 (emacs_mule_string_char): Remove unused extern decls.
5967 (struct iso_2022_spec, struct coding_system):
5968 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5969 (struct emacs_mule_spec): Remove unused field 'full_support'.
5970 All initializations removed.
5971 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5973 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5975 Fix spare memory change (Bug#12286).
5976 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5977 (valid_lisp_object_p): Likewise.
5979 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5981 * window.c (Fset_window_configuration): Record any window's old
5982 buffer if it's replaced (see Bug#8789). If the new current
5983 buffer doesn't appear in the selected window, go to its old
5986 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5988 Special MEM_TYPE_SPARE to denote reserved memory.
5989 * alloc.c (enum mem_type): New memory type.
5990 (refill_memory_reserve): Use new type for spare memory.
5991 This prevents live_cons_p and live_string_p from incorrect
5992 detection of uninitialized objects from spare memory as live.
5994 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5997 * Makefile.in (.PHONY): versioclean -> versionclean.
5999 Remove unused external symbols.
6000 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6001 * window.c (Qwindow_valid_p, decode_valid_window):
6002 Now static, not extern.
6003 * data.c (Qinterval): Remove; unused.
6004 (syms_of_data): Do not define 'interval'.
6005 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6006 * window.h (decode_valid_window):
6009 * character.c, charset.c, chartab.c: Use bool for booleans.
6010 * character.c (lisp_string_width, string_count_byte8)
6011 (string_escape_byte8):
6012 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6013 (load_charset_map_from_file, map_charset_chars)
6014 (Fdefine_charset_internal, define_charset_internal)
6015 (Fdeclare_equiv_charset, find_charsets_in_text)
6016 (Ffind_charset_region, char_charset, Fiso_charset):
6017 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6018 (sub_char_table_set, sub_char_table_set_range)
6019 (char_table_set_range, optimize_sub_char_table)
6020 (map_sub_char_table):
6021 Use bool for boolean.
6022 * character.c (str_to_unibyte): Omit last boolean argument; it was
6023 always 0. All callers changed.
6024 * character.h, charset.h: Adjust to match previous changes.
6025 * character.h (char_printable_p): Remove decl of nonexistent function.
6026 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6027 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6028 are all boolean, so make them single-bit bitfields.
6030 * lisp.h (ASET): Remove attempt to detect side effects.
6031 It was meant to be temporary and it often doesn't work,
6032 because when IDX has side effects the behavior of IDX==IDX
6033 is undefined. See Stefan Monnier in
6034 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6036 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6038 * lisp.h (functionp): New function (extracted from Ffunctionp).
6039 (FUNCTIONP): Use it.
6040 * eval.c (Ffunctionp): Use it.
6042 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6044 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6045 as that's faster and simpler than static storage. Don't bother
6046 with the g_main_context_query overhead if g_main_context_pending
6047 says no events are pending.
6048 (gfds, gfds_size): Remove these static vars.
6049 (xgselect_initialize): Remove; no longer needed.
6050 All uses and decls removed.
6052 * emacs.c (fatal_error_signal_hook): Remove.
6053 All uses removed. This leftover from old code was always 0.
6055 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6056 * casefiddle.c (casify_object, casify_region):
6057 * casetab.c (set_case_table):
6058 * category.c, category.h (word_boundary_p):
6059 * category.h (CHAR_HAS_CATEGORY):
6060 Use bool for booleans, instead of int.
6062 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6064 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6066 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6068 On assertion failure, print backtrace if available.
6069 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6070 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6071 * Makefile.in (LIB_EXECINFO): New macro.
6074 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6075 * bytecode.c (exec_byte_code):
6076 * callint.c (check_mark, Fcall_interactively):
6077 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6078 (getenv_internal, sync_process_alive, call_process_exited):
6079 * lisp.h (USE_SAFE_ALLOCA):
6080 Use bool for booleans, instead of int.
6081 * lisp.h, process.h: Adjust prototypes to match above changes.
6082 * callint.c (Fcall_interactively): Don't assume the mark's
6083 offset fits in 'int'.
6085 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6087 * buffer.c, buffer.h: Use bool for boolean.
6088 * buffer.c (reset_buffer_local_variables)
6089 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6090 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6091 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6092 (overlay_touches_p, overlay_strings, Foverlay_put)
6093 (report_overlay_modification, call_overlay_mod_hooks):
6094 (mmap_enlarge, mmap_set_vars):
6095 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6096 Use bool for booleans, instead of int.
6097 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6098 since the 1-or-0 return value is always ignored anyway.
6099 (mmap_initialized_p):
6100 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6101 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6103 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6105 * bidi.c: Use bool for boolean.
6106 This is a bit more readable, and makes the text segment of bidi.o
6107 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6108 Presumably it's faster too.
6109 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6111 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6112 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6113 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6114 (bidi_explicit_dir_char, bidi_level_of_next_char)
6115 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6116 Use bool for booleans, instead of int.
6117 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6118 (bidi_unshelve_cache): Adjust decls to match code.
6120 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6122 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6125 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6127 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6128 * atimer.h: Include <stdbool.h>.
6130 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6132 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6133 compile time tests instead of run time tests on systems that do
6135 (FRAME_MAC_P): Remove leftover from deleted code.
6136 * frame.c (syms_of_frame): Remove leftover from deleted code.
6138 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6140 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6142 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6144 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6145 Otherwise, the compiler complains about (A?B:C) where B is void
6146 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6147 (fontset_add): Return void, for FONTSET_ADD.
6149 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6151 * alloc.c: Use bool for booleans.
6152 (gc_in_progress, abort_on_gc)
6153 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6154 (dont_register_blocks) [GC_MALLOC_CHECK]:
6155 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6156 (check_string_bytes, make_specified_string, memory_full)
6157 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6158 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6159 (mark_stack, valid_pointer_p, make_pure_string)
6160 (Fgarbage_collect, survives_gc_p, gc_sweep):
6161 Use bool for booleans, instead of int.
6162 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6163 Remove unused local.
6164 * alloc.c (PURE_POINTER_P):
6165 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6166 * editfns.c (Fformat):
6167 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6169 * fns.c (sweep_weak_table):
6170 * lisp.h (suppress_checking, push_message, survives_gc_p)
6171 (make_pure_string, gc_in_progress, abort_on_gc):
6172 * lread.c (readchar, read1):
6173 * print.c (Fprin1_to_string):
6174 * xdisp.c (push_message):
6175 Use bool for booleans affected directly or indirectly by
6178 Make recently-introduced setters macros.
6179 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6180 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6181 (set_fontset_default, set_fontset_fallback): Rename from their
6182 upper-case counterparts, and make them functions rather than macros.
6183 This is more consistent with the other recently-introduced setters.
6184 These don't need to be inline, since they're local.
6186 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6188 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6189 the loop (Bug#12247).
6191 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6193 * lisp.h (vcopy): Use memcpy rather than our own loop.
6194 This fixes a performance regression introduced by the recent
6195 addition of vcopy. This means 'vcopy' will need to be modified
6196 for a copying collector, but that's OK. Also, tighten the
6197 checking in the assertion.
6199 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6201 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6202 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6203 non-base glyph for the width of the base character, according to
6204 what x_draw_composite_glyph_string_foreground expects.
6205 Generate WADJUST value according to composition_gstring_width's
6206 expectations, to produce correct width of the composed character.
6207 Reverse the sign of the DU offset produced by ScriptPlace.
6209 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6211 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6213 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6215 Avoid direct writes to contents member of struct Lisp_Vector.
6216 * lisp.h (vcopy): New function to copy data into vector.
6217 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6218 * fns.c (Ffillarray): Use ASET.
6219 * keyboard.c (timer_check_2): Use AREF and ASET.
6220 (append_tool_bar_item, Frecent_keys): Use vcopy.
6221 * lread.c (read_vector): Use ASET.
6222 * msdos.c (Frecent_doskeys): Use vcopy.
6223 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6224 (Finternal_merge_in_global_face): Use ASET and vcopy.
6225 * xfont.c (xfont_list_pattern): Likewise.
6227 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6229 * window.c (Fwindow_point): For the selected window always return
6230 the position of its buffer's point.
6231 (Fset_window_point): For the selected window always go in its
6232 buffer to the specified position.
6234 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6236 Setter macros for fontsets.
6237 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6238 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6239 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6242 2012-08-20 Glenn Morris <rgm@gnu.org>
6244 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6245 Don't assume that `ln -f' works.
6247 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6249 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6250 and later about non-assignments with no effect. See discussion at
6251 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6254 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6256 Inline setter functions for Lisp_Objects slots of struct specbinding.
6257 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6260 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6262 * window.c (select_window): Always make selected window's buffer
6265 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6267 Use AREF and ASET for docstrings of category tables.
6268 * category.h (CATEGORY_DOCSTRING): Use AREF.
6269 (SET_CATEGORY_DOCSTRING): Use ASET.
6270 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6272 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6274 Inline setter functions for hash table members.
6275 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6276 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6277 (set_hash_key_and_value, set_hash_index, set_hash_next)
6278 (set_hash_hash): New functions.
6279 * charset.c, fns.c: Adjust users.
6281 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6283 Inline getter and setter functions for per-buffer values.
6284 * buffer.h (per_buffer_default, set_per_buffer_default)
6285 (per_buffer_value, set_per_buffer_value): New functions.
6286 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6287 * buffer.c, data.c: Adjust users.
6289 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6291 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6293 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6295 Rely on <config.h> + <unistd.h> to declare 'environ',
6296 as gnulib does this if the system doesn't.
6297 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6298 Remove declaration. MS-Windows declares it on stdlib.h which is
6299 included by conf_post.h.
6300 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6301 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6302 * vm-limit.c: Include <unistd.h>, for 'environ'.
6304 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6305 (start_of_data): Remove decl; mem-limits.h provides it.
6307 * xdisp.c (handle_invisible_prop): Make it a bit faster
6308 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6310 2012-08-19 Chong Yidong <cyd@gnu.org>
6312 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6315 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6317 * .gdbinit: Use call instead of set when calling a function in the
6320 * data.c (set_internal): Don't use set_blv_found.
6321 (Fkill_local_variable): Likewise.
6323 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6325 * nsfont.m (ns_ascii_average_width): Ensure the string
6326 ascii_printable is initialized with a null-terminated character
6327 array. Otherwise, it can contain undesired extra characters.
6329 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6331 port new setting code to Sun C 5.8 2005/10/13
6332 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6333 Return void, not Lisp_Object. Otherwise, the compiler
6334 complains about (A?B:C) where B is void and C is Lisp_Object
6335 when compiling CHAR_TABLE_SET, due to the recent change to
6336 the API of sub_char_table_set_contents.
6338 2012-08-18 Chong Yidong <cyd@gnu.org>
6340 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6341 for the string case (Bug#3874).
6343 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6345 * buffer.h (BSET): Remove (Bug#12215).
6346 Replace all uses with calls to new setter functions.

7278 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7279 checking subscripts; problem introduced with the recent
7280 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7281 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7282 since it's used in non-static inline functions now.
7284 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

7311 (INLINE_HEADER_END): New macros.
7312 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7334 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7336 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7337 This how ASET and AREF are supposed to work, and makes
7338 it easier to think about future improvements. See
7339 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7340 * charset.h (set_charset_attr): New function.

7722 (w32_kbd_patch_key, key_event): Use the codepage returned by
7723 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
7724 (key_event): use uChar.UnicodeChar only if

7755 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7756 enumeration constants, as PURE and HEAP are too general, and clash
7757 with other headers and sources, such as gmalloc.c and the
7758 MS-Windows system headers. All users changed.
7760 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7762 Revert last save_excursion_save and save_excursion_restore changes.
7763 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7776 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7777 arms of an 'if', not using conditional expressions; otherwise GDB
7778 complains about the types in the unevaluated arm when the argument
7779 is an integer literal.
7780 (xgetint): Simplify expression.
7781 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7782 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7783 Zaretskii in <http://bugs.gnu.org/12036#13>.
7784 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7785 needed now that we have gdb_make_enums_visible.
7786 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7787 (enum enum_USE_LSB_TAG):
7788 New enum types, packaging up enums that need to be exported to GDB.

7812 * lisp.h (struct Lisp_Excursion): New data type.
7813 (PVEC_EXCURSION): New pseudovector type.

7830 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7831 emacs.c, as this is a more-suitable home. Had this been done earlier
7832 the fix for 12036 would have avoided some of the problems noted in
7833 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7834 would have been more obvious.
7835 * emacs.c: Do not include <verify.h>; no longer needed.
7836 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7837 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7838 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

7843 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7844 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7845 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7846 not be usable in #if. This simplifies things.
7848 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7850 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7855 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7856 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7857 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7858 Adjust to changes in lisp.h and emacs.c, by using
7859 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7860 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7861 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7862 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7863 instead of gdb_valbits.
7864 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7865 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7866 instead of gdb_array_mark_flag.
7867 (xboolvector): Get size from $->size, not $->header.size.
7868 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7869 (xreload, hook-run, hookpost-run): Remove.
7870 * emacs.c: Include <verify.h>.
7871 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7872 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7874 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7875 (gdb_USE_LSB_TAG): New enum constants.
7876 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7877 Also define these as enum constants, so they're visible to GDB.
7878 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7879 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7880 as constants, so they're visible to GDB.

7883 Now enum constants, not macros, so they're visible to GDB.
7884 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7885 more convenient now. All uses changed.
7886 (VALMASK) [USE_LSB_TAG]: Also define in this case.

7896 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7897 add argument, tune behavior, and adjust all callers.
7899 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7901 Use typedef for EMACS_INT, EMACS_UINT.
7902 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7903 than macros. This simplifies debugging in the usual case, since
7904 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7905 and it allows expressions involving EMACS_INT casts.
7906 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7908 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7918 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7920 Adjust buffer text indirection counters at the end of Fkill_buffer.
7921 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7922 buffer is definitely dead. This should really fix an issue reported
7923 by Christoph Scholtes again. (Bug#12007).
7924 (init_buffer_once): Initialize indirection counters of
7925 buffer_defaults and buffer_local_symbols (for sanity and safety).
7927 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7929 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7930 and continuation glyphs on tooltip frames, leave them at zero.

7933 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7935 Simplify copy_overlay.
7936 * buffer.c (copy_overlay): Simplify. Use build_marker.

7958 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7960 Swap buffer text indirection counters in Fbuffer_swap_text.
7961 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7962 This avoids crash reported by Christoph Scholtes at
7963 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7965 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7967 * nsmenu.m (Popdown_data): New struct.
7968 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7970 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7971 (initWithContentRect): Make imgView and contentView non-static
7972 and autorelease them. Also autorelease img and matrix (Bug#12005).
7973 (dealloc): Remove (Bug#12005).
7975 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7977 Adjust consing_since_gc when objects are explicitly freed.

7990 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7992 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7993 as it's limited by the amount of memory, not by INT_MAX.
7995 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7997 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7998 in special-event-map. See the discussion at

8057 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8058 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8059 Adjust users accordingly.
8060 * font.h (font_open_by_name): Adjust prototype.

8079 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8080 'for_each_per_buffer_object_at'.
8081 All uses changed. It's better to use upper-case for macros that
8082 cannot be implemented as functions, to give the reader a clue
8083 that they're special.

8651 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
8652 since nothing has defined it on these platforms.

8668 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
8669 function attribute, so we only use it if it exists in the
8672 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
8674 Avoid call to strlen in fast_c_string_match_ignore_case.

8721 * s/aix4-2.h (unix): Remove; no longer needed.
8723 EMACS_TIME simplification (Bug#11875).
8724 This replaces macros (which typically do not work in GDB)
8725 with functions, typedefs and enums, making the code easier to debug.
8726 The functional style also makes code easier to read and maintain.
8727 * systime.h: Include <sys/time.h> on all hosts, not just if
8728 WINDOWSNT, since 'struct timeval' is needed in general.
8729 (EMACS_TIME): Now a typedef, not a macro.
8730 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8732 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

8737 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8738 which are not functions. All uses rewritten to use:
8739 (make_emacs_time): New function.
8740 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8741 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8742 not functions. All uses rewritten to use the following, respectively:
8743 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8744 (add_emacs_time, sub_emacs_time): New functions.
8745 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8746 * fileio.c (Fcopy_file):
8747 * xterm.c (XTflash): Get the current time closer to when it's used.
8748 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8762 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8763 (menu_separator_name_p):
8764 * nsmenu.m (ns_update_menubar):
8765 Prefer memcmp to strncmp when either will do.
8766 * nsterm.m: Include <ftoastr.h>.
8768 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8769 Prefer snprintf to strncpy.
8770 * nsterm.m (ns_term_init):
8771 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8772 * nsterm.m (ns_term_init):
8773 Avoid the need for strncpy, by using build_string or
8774 make_unibyte_string directly. Use dtoastr, not snprintf.
8775 * process.c (Fmake_network_process): Diagnose service names that
8776 are too long, rather than silently truncating them or creating
8777 non-null-terminated names.
8778 (Fnetwork_interface_info): Likewise, for interface names.
8779 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8780 Prefer sprintf to strncat.
8781 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8782 Prefer vsnprintf to vsprintf + strncpy.
8784 2012-07-10 Glenn Morris <rgm@gnu.org>
8786 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8787 Clarify fallback case.
8789 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

8792 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8793 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8794 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8795 where argument type is known to be a Lisp_Cons.
8797 2012-07-10 Tom Tromey <tromey@redhat.com>
8799 * bytecode.c (BYTE_CODE_THREADED): New macro.

8807 Optimize pure C strings initialization.
8808 * lisp.h (make_pure_string): Fix prototype.
8809 (build_pure_c_string): New function, defined as static inline. This
8810 provides a better opportunity to optimize away calls to strlen when
8811 the function is called with compile-time constant argument.
8812 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8813 argument, adjust users accordingly. Use build_pure_c_string where
8815 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8816 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8817 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8819 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8821 Avoid calls to strlen in miscellaneous functions.
8822 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8823 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8824 * lread.c (openp): Likewise.
8826 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8828 Avoid calls to strlen in path processing functions.
8829 * fileio.c (file_name_as_directory): Add comment. Change to add
8830 srclen argument and return the length of result. Adjust users

8834 Adjust users accordingly.
8835 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8837 2012-07-10 Glenn Morris <rgm@gnu.org>

8844 * s/gnu.h (DATA_START): Move definitions to configure.
8846 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8847 We include usg5-4-common.h, which defines them both.
8849 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8850 O_RDONLY already includes it).
8852 Stop ns builds setting the EMACSLOADPATH environment variable.
8853 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8854 Now it does not set EMACSLOADPATH, just returns the load-path string.
8855 * nsterm.h: Update accordingly.
8856 * lread.c [HAVE_NS]: Include nsterm.h.
8857 (init_lread) [HAVE_NS]: Use ns_load_path.
8858 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8860 2012-07-09 Glenn Morris <rgm@gnu.org>
8862 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8863 since the included bsd-common.h does so.
8865 Stop ns builds setting the EMACSPATH environment variable.
8866 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8867 (ns_init_paths): Do not set EMACSPATH.
8868 * nsterm.h (ns_exec_path): Add it.
8869 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8872 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8874 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8876 * process.c (wait_reading_process_output): 'waitchannels' was unset
8877 when read_kbd || !NILP (wait_for_cell); fix this.
8879 Add GCC-style 'const' attribute to functions that can use it.
8880 * character.h (char_resolve_modifier_mask):
8881 * keyboard.h (make_ctrl_char):
8882 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8891 Add decls with ATTRIBUTE_CONST.
8893 Minor improvements to make_formatted_string.
8894 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8895 where int is good enough, as vsprintf returns an int.
8896 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8898 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8900 Use make_formatted_string to avoid double length calculation.
8901 * lisp.h (make_formatted_string): New prototype.
8902 * alloc.c (make_formatted_string): New function.
8903 * buffer.c (Fgenerate_new_buffer_name): Use it.

8907 * frame.c (make_terminal_frame, set_term_frame_name)
8908 (x_report_frame_params): Likewise.

8925 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8927 Move marker debugging code under MARKER_DEBUG.
8928 * marker.c (MARKER_DEBUG): Move marker debugging code under
8929 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8930 for bootstrap with --enable-checking (~3x slowdown reported
8931 by Juanma Barranquero <lekktu@gmail.com>).
8932 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8934 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8936 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8937 See <http://bugs.gnu.org/11825#29>.
8939 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8941 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8942 has no font, use the frame's font. (Bug#11813)
8943 (display_line): Add commentary about displaying truncation glyphs
8945 (produce_special_glyphs): Move here from term.c.
8947 * term.c (produce_special_glyphs): Move to xdisp.c.
8949 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8952 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8954 * xdisp.c (display_line): Avoid warning about implicit declaration
8957 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8959 * lisp.h: Remove empty conditional.
8961 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8963 * lread.c (load_path_check): Now static.
8965 Fix some minor --with-ns problems found by static checking.
8966 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8967 (x_set_font) [!HAVE_X_WINDOWS]:
8968 * image.c (xpm_load_image) [HAVE_NS]:
8969 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8970 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8971 Remove unused local.
8972 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8973 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8974 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8975 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8976 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8977 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8978 Fix pointer signedness problem.
8979 * xfaces.c (FRAME_X_FONT_TABLE):
8980 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8982 2012-07-07 Glenn Morris <rgm@gnu.org>
8984 * lread.c (load_path_check): New function, split from init_lread.
8985 (init_lread): Reorganize. Motivation:
8986 If EMACSLOADPATH is set, check/warn about that rather than the
8987 defaults, which we are not going to use. Hence we can remove
8988 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8989 Don't warn if site-lisp directories are missing.
8990 If not installed, start from a blank load-path, since
8991 PATH_LOADSEARCH refers to the eventual installation directories.
8993 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8995 Support truncation and continuation glyphs on GUI frames, when
8996 fringes are disabled. (Bug#11832)
8997 * xdisp.c (init_iterator): Get dimensions of truncation and
8998 continuation glyphs even if on GUI frames.
8999 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9000 or both, are absent.
9001 (start_display, move_it_in_display_line_to): Handle the case of a
9002 GUI frame without a fringe to display continuation or truncation
9004 (insert_left_trunc_glyphs): Support GUI frames: make sure
9005 truncation glyphs overwrite enough glyphs from the current line to
9006 have sufficient space in pixels.
9007 (display_line): Support truncation and continuation glyphs on GUI
9008 frames. If some spare pixels are left on the line after inserting
9009 the truncation glyphs, fill that space with a stretch glyph of a
9010 suitably computed width.
9012 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9013 produce_glyphs, to support GUI sessions.
9015 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9017 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9019 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9021 Do not require float-time's arg to fit in time_t (Bug#11825).
9022 This works better on hosts where time_t is unsigned, and where
9023 float-time is applied to the (negative) difference between two times.
9024 * editfns.c (decode_time_components): Last arg is now double *,
9025 not int *, and means to store all the result as a double, without
9026 worrying about whether the seconds part fits in time_t.
9027 All callers changed.
9028 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9029 All callers changed.
9030 (Ffloat_time): Do not fail merely because the specified time falls
9031 outside of time_t range.
9033 2012-07-07 Glenn Morris <rgm@gnu.org>

9075 * process.c: Avoid unnecessary calls to gettime.
9076 (wait_reading_process_output): Don't get the time of day
9077 when gobbling data immediately and not waiting, as there's no need
9078 for it in that case. This removes a FIXME.
9080 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9082 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9083 is defined (Bug#11768).

9093 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9095 Compile marker debugging code only if ENABLE_CHECKING is defined.
9096 * marker.c (byte_char_debug_check, count_markers):
9097 Use only if ENABLE_CHECKING is defined.
9098 (byte_debug_flag): Remove.
9099 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9100 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9102 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9104 Avoid code repetition in marker-related functions.

9142 Port to OpenBSD 5.1 amd64.
9143 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9144 This is needed for OpenBSD, and should be harmless on all BSD systems.
9145 Also, include <sys/sysctl.h>, as it should be available on all
9146 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9147 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9148 use p_pid member, not kp_proc.pid.
9150 2012-07-06 Glenn Morris <rgm@gnu.org>
9152 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9154 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9165 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9167 Omit needless casts involving void * pointers and allocation.
9168 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9169 as the former is more robust if P's type is changed.
9170 Prefer xzalloc to xmalloc + memset 0.
9171 Simplify malloc-or-realloc to realloc.
9172 Don't worry about xmalloc returning a null pointer.
9173 Prefer xstrdup to xmalloc + strcpy.
9174 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9176 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9177 alloca of a constant.

9181 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9182 hscroll is larger than the line width. Fixes long and futile
9183 looping inside extend_face_to_end_of_line (on a TTY) producing
9184 glyphs that are not needed and thrown away.
9186 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9188 * marker.c (set_marker_restricted_both): Simplify by using

9202 followed by gtk_box_set_homogeneous (Bug#11768).
9203 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9204 (update_theme_scrollbar_width, xg_create_scroll_bar):
9205 Use gtk_scrollbar_new (Bug#11768).
9206 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

9214 * xdisp.c (window_hscroll_limited): New function.
9215 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9216 coordinates when window's hscroll is set to insanely large
9219 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

9283 Problem reported by Troels Nielsen in
9284 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

9288 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9289 This should be fixed in a better way; see Eli Zaretskii in
9290 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9291 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9293 * fileio.c (time_error_value): Rename from special_mtime.
9294 The old name's problems were noted by Eli Zaretskii in
9295 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9297 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9298 This variable's comment says Emacs needs at least one GDB-visible
9299 symbol of type enum pvec_type, to work around GDB problems.
9300 The symbol's value doesn't matter.
9302 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9303 that causes compilation to fail on pre-C99 compilers.
9305 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9307 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9331 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9332 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9333 abusing vector->header.next.nbytes.
9334 (live_vector_p): Use PVEC_TYPE.
9335 (mark_object): Adapt code to extract pvectype. Use switch.
9337 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9339 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9340 Tighten new eassert a bit.
9342 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9344 Fix compilation with --enable-gcc-warnings and -O1
9346 * doprnt.c (doprnt): Change type of tem to int, initialize
9347 to avoid compiler warning. Add eassert.
9348 * search.c (simple_search): Initialize match_byte to avoid
9349 compiler warning. Add eassert.
9351 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9353 Avoid weird behavior with large horizontal scrolls.
9354 Without this change, for example, large hscroll values would
9355 mess up Emacs's display on Fedora 15 x86, presumably due to
9356 overflows in int calculations in the display code.
9357 Also, if buffers had long lines, Emacs would freeze.
9358 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9359 (set_window_hscroll): New function, containing the old guts of
9360 Fset_window_hscroll. Return the clipped value.
9361 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.

9373 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9374 since GCC 4.4.6 issues a bogus warning for them.
9376 Fix bugs in file timestamp newness comparisons.
9377 * fileio.c (Ffile_newer_than_file_p):
9378 * lread.c (Fload): Use full timestamp resolution of files,
9379 not just the 1-second resolution, so that files that are only
9380 slightly newer still count as newer.
9381 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9382 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9384 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9386 * fileio.c: Improve handling of file time marker. (Bug#11852)

9393 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9394 marker for non-existing file. (Bug#11852)
9396 2012-07-03 Glenn Morris <rgm@gnu.org>
9398 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9399 and did not make it into globals.h).
9401 2012-07-03 Tom Tromey <tromey@redhat.com>

9441 * lisp.h (Frandom): Make it visible to C.
9442 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new

9464 avoid calls to mallopt if zero_vector is returned.
9466 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9468 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9469 is enabled, avoid dereferencing NULL current_sblock if
9472 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9474 Cleanup basic buffer management.

9488 Lisp area of struct buffer.
9489 (mark_object): Use it. Adjust marking of misc objects
9490 and related comments.
9492 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9494 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9495 wrapper that is not needed because the wrapped code is a no-op (zero
9496 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9497 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9499 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9501 * alloc.c (mark_buffer): Simplify. Remove prototype.
9502 (mark_object): Add comment. Reorganize marking of vector-like
9503 objects. Use CHECK_LIVE for all vector-like objects except buffers
9504 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9505 Avoid redundant calls to mark_vectorlike for bool vectors.
9507 2012-06-30 Glenn Morris <rgm@gnu.org>
9509 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9511 * epaths.in (PATH_SITELOADSEARCH): New.
9512 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9513 This is rather than relying on --enable-locallisppath elements
9514 having "site-lisp" in their names. (Bug#10208#25, 11658)
9516 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9518 * w32proc.c (sys_select): Accept and ignore one more argument.
9520 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9522 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9523 (pselect) [!MS_DOS]: Redirect to sys_select.
9525 * sysdep.c: Don't include dos.h and dosfns.h.
9527 * process.c (sys_select):
9528 * msdos.c (sys_select): Accept one more argument and ignore it.
9530 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9531 adapt data types and code to that.
9534 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9535 which clashes with the gnulib function of the same name.
9537 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9539 * font.c (font_style_to_value, font_style_symbolic)
9540 (font_prop_validate_style): Add type checks for values in
9543 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9545 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9548 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9550 * xdisp.c (try_window_id): Undo last change.
9552 * w32.c (getwd): Adjust commentary about startup_dir.
9553 (init_environment): Always call sys_access, even in non-MSVC
9554 builds. Don't chdir to the directory of the Emacs executable.
9555 This undoes code from 1997 which was justified by the need to
9556 "avoid conflicts when removing and renaming directories". But its
9557 downside was that every relative file name was being interpreted
9558 relative to the directory of the Emacs executable, which can never
9559 be TRT. In particular, it broke sys_access when called with
9560 relative file names.
9561 (sys_access): Map GetLastError to errno.
9563 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9565 * window.h (struct window): Change type of 'fringes_outside_margins'
9566 to bitfield. Fix comment. Adjust users accordingly.
9567 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9569 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9572 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9574 * gnutls.c (emacs_gnutls_handshake):
9575 Add QUIT to make the loop interruptible.
9577 2012-06-29 Glenn Morris <rgm@gnu.org>
9579 * charset.c (init_charset): Make lack of etc/charsets fatal.
9581 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9583 * editfns.c (region_limit): Fix type mismatch.
9585 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9587 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9588 undefined. Convert from xassert to eassert.
9589 * nsmenu.m: Convert from xassert to eassert.
9590 * nsterm.m: Likewise.
9592 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9594 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9596 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9598 Avoid integer overflow on scroll-left and scroll-right.
9599 * window.c (HSCROLL_MAX): New macro.
9600 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9601 overflow when requested scroll falls outside ptrdiff_t range.
9603 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9605 * window.h (struct window): Change type of 'hscroll',
9606 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9607 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9608 Adjust users accordingly.
9609 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9610 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9611 from EMACS_INT to ptrdiff_t.
9612 (make_window): Omit redundant initialization.
9614 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9616 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9618 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9620 * window.h (struct window): Change type of 'use_time' and
9621 'sequence_number' from Lisp_Object to int.
9622 * frame.c (make_frame): Adjust users accordingly.
9623 * print.c (print_object): Likewise.
9624 * window.c (select_window, Fwindow_use_time, make_parent_window)
9625 (make_window): Likewise.
9627 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9629 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9630 enabled with --enable-checking=[all,glyphs] configure option.
9631 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9632 adjust comments accordingly.

9681 * alloc.c (allocate_string_data): Remove dead code.
9682 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
9683 avoid GCC warning about unused macro.
9685 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9687 * alloc.c (allocate_string): Omit intervals initialization.
9688 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9689 as in make_pure_string and make_pure_c_string.
9691 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9693 * alloc.c (allocate_string): Fix last change.
9695 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9697 * alloc.c (allocate_string): Remove two redundant calls
9698 to memset, add explicit initialization where appropriate.

9702 * lisp.mk (lisp): Remove paths.elc.
9704 2012-06-27 Chong Yidong <cyd@gnu.org>
9706 * doc.c (Fsubstitute_command_keys): Fix punctuation.
9708 2012-06-26 John Wiegley <johnw@newartisans.com>
9710 * unexmacosx.c (copy_data_segment): Add two section names used
9711 on Mac OS X Lion: __mod_init_func and __mod_term_func.
9713 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
9714 when building with Clang.
9716 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>
9718 * eval.c (Fapply): Allow calling it with a single argument.
9720 2012-06-26 Eli Zaretskii <eliz@gnu.org>
9722 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
9723 _stricmp and _strnicmp.
9724 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
9726 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9728 * alloc.c (allocate_window): Zero out non-Lisp part of newly
9730 (allocate_process): Likewise for new process.
9731 (allocate_terminal): Change to use offsetof.
9732 (allocate_frame): Likewise.

9743 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9745 * alloc.c: Remove build_string.
9746 * lisp.h: Define build_string as static inline. This provides
9747 a better opportunity to optimize away calls to strlen when the
9748 function is called with compile-time constant argument.
9749 * image.c (imagemagick_error): Convert to build_string.
9750 * w32proc.c (sys_spawnve): Likewise.
9751 * xterm.c (x_term_init): Likewise.
9753 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9755 Use sprintf return value instead of invoking strlen on result.
9756 In the old days this wasn't portable, since some sprintf
9757 implementations returned char *. But they died out years ago and
9758 Emacs already assumes sprintf returns int.
9759 Similarly for float_to_string.
9760 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9761 * ccl.c (ccl_driver):
9762 * character.c (string_escape_byte8):
9763 * data.c (Fnumber_to_string):
9764 * doprnt.c (doprnt):
9765 * print.c (print_object):
9766 * xdisp.c (message_dolog):
9767 * xfns.c (syms_of_xfns):
9768 Use sprintf or float_to_string result to avoid need to call strlen.
9769 * data.c (Fnumber_to_string):
9770 Use make_unibyte_string, since the string must be ASCII.
9771 * lisp.h, print.c (float_to_string): Now returns int length.
9772 * term.c (produce_glyphless_glyph):
9773 Use sprintf result rather than recomputing it.
9775 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9776 * Makefile.in (ALL_CFLAGS):
9777 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9778 * gmalloc.c, regex.c: Include <config.h> unconditionally.
9780 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9782 * dispextern.h (xstrcasecmp): Define to library function
9783 strcasecmp if available.
9784 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
9786 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
9788 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):
9789 Avoid comma operator.

9799 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9801 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9802 sprintf already null-terminates its output.
9804 * xfns.c (x_window): Remove redundant cast.
9806 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9808 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9809 `const char *' to `char *' to avoid compiler warning.
9811 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9813 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9814 instead of truncating it to 63 (admittedly a generous limit).
9816 * process.c: Fix spelling and caps in comments.
9818 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9820 * emacs.c (setpgrp): Remove definition, unused.

9830 (SYSTIME_H): Add nt/inc/sys/time.h.
9832 * systime.h [WINDOWSNT]: Include sys/time.h.
9834 * s/ms-w32.h (struct timespec): Definition moved from
9835 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
9837 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

9864 Use _Noreturn rather than NO_RETURN.
9865 No need for separate decl merely because of _Noreturn.
9866 * sound.c (sound_warning, parse_sound):
9867 Remove unnecessary forward decls.
9869 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9871 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9872 * lisp.h (WAIT_READING_MAX): New macro.
9873 * dispnew.c (Fsleep_for, sit_for):
9874 * keyboard.c (kbd_buffer_get_event):
9875 * process.c (Faccept_process_output):
9876 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9877 This improves on the previous patch, which introduced a bug
9878 when time_t is unsigned and as wide as intmax_t.
9879 See <http://bugs.gnu.org/9000#51>.
9881 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9883 * dispnew.c (sit_for, Fsleep_for):
9884 * keyboard.c (kbd_buffer_get_event):
9885 * process.c (Faccept_process_output): Avoid compiler warnings when
9886 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
9888 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
9890 * makefile.w32-in: Update dependencies.
9892 * w32.c (ltime): Add return type and declare static.
9893 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
9895 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9897 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9898 Privately reported by Herbert J. Skuhra.
9899 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9901 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9902 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9904 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9906 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9907 last argument of make_unibyte_string.
9909 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9910 language ID in the event parameters.
9912 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9913 event.code, not the obscure "character set ID".
9915 2012-06-23 Chong Yidong <cyd@gnu.org>
9917 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9919 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9921 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
9922 * w32.c (fdutimens): New function.
9924 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
9926 * s/ms-w32.h (pselect): Redirect to sys_select.
9928 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.

9931 in the logic of incrementing and decrementing the value of
9932 use_relocatable_buffers.
9934 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9936 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9937 Privately reported by Herbert J. Skuhra.

9944 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9946 Support higher-resolution time stamps (Bug#9000).
9947 The time stamps are only nanosecond-resolution at the C level,
9948 since that's the best that any real-world system supports now.
9949 But they are picosecond-resolution at the Lisp level, as that's
9950 easy, and leaves room for future OS improvements.
9952 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9955 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9956 Don't get current time unless it's needed.
9958 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9959 now provides it if it's absent.
9960 (start_atimer): Port to higher-res time stamps.
9961 Check for time stamp overflow. Don't get current time more
9962 often than is needed.
9964 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9965 Include systime.h, not time.h.
9966 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9968 * dired.c: Include stat-time.h.
9969 (Ffile-attributes): File times now have higher resolution.
9971 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9972 (struct image): Timestamp now has higher resolution.
9974 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9975 has at least microseconds now. All uses removed.
9976 (update_frame, update_single_window, update_window, update_frame_1)
9977 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9978 (duration_to_sec_usec): Remove; no longer needed.
9980 * editfns.c (time_overflow): Now extern.
9981 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9982 (float-time, Fformat_time_string, Fcurrent_time_string)
9983 (Fcurrent_time_zone): Accept and generate higher-resolution
9985 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9986 (decode_time_components, lisp_seconds_argument): New functions.
9987 (make_time): Now static.
9988 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9989 Report an error if the time is invalid, rather than having the caller
9992 * fileio.c: Include <stat-time.h>
9993 (Fcopy_file): Copy higher-resolution time stamps.
9994 Prefer to set the time stamp via a file descriptor if that works.

10008 Check for time stamp overflow.
10009 (read_char, kbd_buffer_get_event, timer_start_idle)
10010 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10011 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10012 Port to higher-resolution time stamps. Do not assume time_t is signed.
10013 (decode_timer): New function. Timers are now vectors of length 9,
10014 not 8, to accommodate the picosecond component.
10015 (timer_check_2): Use it.
10017 * nsterm.m (select_timeout, timeval_subtract): Remove.
10018 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10019 as they're a bit more accurate and handle overflow better.
10020 (ns_select): Change prototype to be compatible with pselect.
10021 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10022 * nsterm.h (ns_select): Adjust prototype.
10024 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes

10039 (wait_reading_process_output):
10040 Port to ns-resolution time stamps.
10041 (Faccept_process_output, wait_reading_process_output):
10042 Check for time stamp overflow. Do not assume time_t is signed.
10043 (select_wrapper): Remove; we now use pselect.
10044 (Fprocess_attributes): Now generates ns-resolution time stamps.
10046 * sysdep.c: Include utimens.h. Don't include utime.h
10047 or worry about struct utimbuf; gnulib does that for us now.
10048 (gettimeofday): Remove; gnulib provides a substitute.
10049 (make_timeval): New function.
10050 (set_file_times): Now sets ns-resolution time stamps.
10051 New arg FD; all uses changed.

10054 Now returns ns-resolution time stamp. All uses changed.
10055 Check for time stamp overflow.
10057 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10058 provides a substitute now.
10060 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10061 since it guarantees struct timespec.
10062 (EMACS_TIME): Now struct timespec, so that we can support
10063 ns-resolution time stamps.
10064 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10065 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10066 (EMACS_USECS): Remove.
10067 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10068 so multiply the arg by 1000 before storing it.
10069 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10071 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10078 (make_timeval, make_lisp_time, decode_time_components): New decls.
10079 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10080 that it mishandled time_t overflow. You can't compare by subtracting!
10081 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10082 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10084 * term.c: Include <sys/time.h>.
10085 (timeval_to_Time): New function, for proper overflow wraparound.
10086 (term_mouse_position, term_mouse_click): Use it.
10088 * undo.c (record_first_change): Support higher-resolution time stamps
10089 in the undo buffer.
10090 (Fprimitive_undo): Use them when restoring time stamps.
10092 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10093 (w32_get_internal_run_time):
10094 Port to higher-resolution Emacs time stamps.
10095 (ltime): Now accepts single 64-bit integer, as that's more convenient
10098 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10100 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10101 for compatibility with pselect. Support ns-resolution time stamps.
10103 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10105 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10106 Check for time stamp overflow, and support ns-resolution time stamps.
10108 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10109 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10110 (timeval_subtract): Remove; no longer needed.
10111 (XTflash, XTring_bell, x_wait_for_event):
10112 Port to ns-resolution time stamps. Don't assume time_t is signed.

10118 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10120 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10121 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10122 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10123 staticidx goes up to 1597 out of 1600 = 0x640.)
10125 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10127 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10128 Otherwise, the umask might be mistakenly 0 while handling input signals.
10130 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10132 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10138 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10139 access to `contents' member of Lisp_Vector objects with AREF and ASET
10142 2012-06-19 Chong Yidong <cyd@gnu.org>
10144 * frame.c (delete_frame): When selecting a frame on a different
10145 text terminal, do not alter the terminal's top-frame.

10148 frame's selected window and its terminal's top-frame.
10149 (unwind_format_mode_line): Restore them.
10150 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10152 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

10161 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10162 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10163 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10164 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10171 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10173 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10174 gets killed during executing of this function (Bug#11665).
10175 Try to always return Qt when the buffer has been actually killed.
10176 (Vkill_buffer_query_functions): In doc-string say that functions
10177 run by this hook should not change the current buffer.
10179 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10181 Fix recently-introduced process.c problems found by static checking.

10201 * lisp.h (eassert): Assume C89 or later.
10202 This removes the need for CHECK.
10203 (CHECK): Remove. Its comments about always evaluating its
10204 argument were confusing, as 'eassert' typically does not evaluate
10207 * coding.c (produce_chars): Use ptrdiff_t, not int.
10209 * xterm.c (x_draw_underwave): Check for integer overflow.
10210 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10397 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10398 Use an inline function on all platforms when using the union type,
10399 since this is simpler and 'static inline' can be used portably

10541 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10543 * doprnt.c (doprnt): Truncate multibyte char correctly.
10544 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10545 would mishandle a string argument "Xc" if X was a multibyte
10546 character of length 2: it would truncate after X's first byte
10547 rather than including all of X.
10549 2012-06-06 Chong Yidong <cyd@gnu.org>
10551 * buffer.c (word_wrap): Doc fix.

10598 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10600 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10601 Convert pctcpu and pctmem to Lisp float properly.
10602 Let the compiler fold better, as 100.0/0x8000 is exact.
10604 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10606 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10616 bitfields where appropriate, remove unused fields.
10617 * window.h (struct window): Remove unused 'last_mark_x' and
10618 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10619 change its type from Lisp_Object to bitfield.
10620 Change type of 'force_start', 'optional_new_start',
10621 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10622 fields from Lisp_Object to bitfield. Adjust users accordingly.
10624 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10626 Pacify gcc -Wdouble-precision when using Xaw.
10627 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10628 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10629 Use 'float' consistently, rather than 'float' in most places
10630 and 'double' in a couple of places.
10632 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10634 * xdisp.c (handle_stop): Detect whether we have overlay strings
10635 loaded by testing it->current.overlay_string_index to be
10636 non-negative, instead of checking whether n_overlay_strings is
10637 positive. (Bug#11587)
10639 2012-05-31 Chong Yidong <cyd@gnu.org>
10641 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10647 * search.c (search_buffer): Remove calls to
10648 r_alloc_inhibit_buffer_relocation, as it is now called by
10649 maybe_unify_char, which was the cause of relocation of buffer text
10652 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10654 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10655 for the duration of call to load_charset, to avoid problems with
10656 callers of maybe_unify_char that access buffer text through C
10659 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10660 decrement the inhibition flag, instead of just setting or
10663 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10665 Remove obsolete '#define static' cruft.
10666 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10667 This #undef was "temporary" in 2000; it is no longer needed
10668 now that '#define static' has gone away.
10669 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10670 (gray_bitmap_bits): Remove; no longer needed.
10671 All uses replaced with definiens.

10679 Define only on platforms that need it.
10680 * emacs.c: Include <sys/gmon.h> when profiling.
10681 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10682 (__executable_start): Remove decl, since lisp.h does it now.
10683 (safe_bcopy): Remove decl; no longer has that name.
10684 (main): Coalesce #if into single bit of code, for simplicity.
10685 Cast pointers to uintptr_t, since standard libraries want integers
10687 * lisp.h (__executable_start): New decl.
10689 2012-05-31 Glenn Morris <rgm@gnu.org>
10691 * image.c (Fimagemagick_types): Doc fix.

10714 Do not create empty overlays with the evaporate property (Bug#9642).
10715 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10716 Bug#9642, but explicitly check that the buffer the overlay would
10717 be moved to is live and rearrange lines to make sure that errors
10718 will not put the overlay in an inconsistent state.
10719 (Fdelete_overlay): Cosmetics.
10721 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10723 * w32term.c (my_bring_window_to_top): New function.
10724 (x_raise_frame): Use handle returned by DeferWindowPos, which
10725 could be different from the original one.

10738 This avoids undefined behavior that might cause the eassert
10739 to not catch an out-of-range value.
10741 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10743 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

10757 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10758 Only r_alloc_inhibit_buffer_relocation needed to be added;
10759 the others were already declared.
10761 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10762 before checking whether it's out of range. Put the check inside
10764 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10766 2012-05-27 Ken Brown <kbrown@cornell.edu>

10778 they are now on lisp.h.
10780 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10782 * search.c (search_buffer): Use it to inhibit relocation of buffer
10783 text while re_search_2 is doing its job, because re_search_2 is
10784 passed C pointers to buffer text. (Bug#11519)
10786 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10787 Update value to 24.
10789 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10790 state after an additional call to move_it_in_display_line_to, keep
10791 the values of it->max_ascent and it->max_descent found for the
10793 (pos_visible_p): Revert the comparison against bottom_y to what it
10794 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10797 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10799 Fix coding-related core dumps with gcc -ftrapv.
10800 The code was computing A - B, where A and B are pointers, and B is
10801 random garbage. This can lead to core dumps on platforms that
10802 have special pointer registers, and it also leads to core dumps on
10803 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10804 A - B only when B is initialized properly.
10805 * coding.c (coding_set_source, coding_set_destination): Return void.
10806 (coding_change_source, coding_change_destinations): New functions,

10818 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10820 * w32console.c: Include window.h.
10821 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10823 (initialize_w32_display): Initialize mouse-highlight data.
10825 * w32inevt.c: Include termchar.h and window.h.
10826 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10827 moves, call note_mouse_highlight. If help_echo changed, call
10828 gen_help_event to produce help-echo message in the echo area.
10829 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10832 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10834 * lread.c (read1): Simplify slightly to avoid an overflow warning
10835 with GCC 4.7.0 on x86-64.
10837 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10839 * bidi.c (bidi_mirror_char): Revert last change: an int is
10840 definitely wide enough here.

10852 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10854 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10855 (allocate_pseudovector):
10856 Use int, not EMACS_INT, where int is wide enough.
10857 (inhibit_garbage_collection, Fgarbage_collect):
10858 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

10877 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10878 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10879 (validate_region): Omit unnecessary test for b <= e,
10880 since that's guaranteed by the previous test.
10881 (adjust_overlays_for_delete): Avoid pos + length overflow.
10882 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10883 (report_overlay_modification):
10884 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10885 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10886 Omit pointer cast, which isn't needed anyway, and doesn't work
10887 after the EMACS_INT -> ptrdiff_t change.
10888 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10889 * buffer.h: Adjust decls to match defn changes elsewhere.

10893 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10894 not int, to avoid needless 32-bit limit on 64-bit hosts.
10895 (exec_byte_code): Use tighter memory-full test, one that checks
10896 for alloca overflow. Don't compute the address of the object just
10897 before an array, as that's not portable. Use EMACS_INT, not
10898 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10899 * callint.c (Fcall_interactively):
10900 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10901 * callproc.c (call_process_kill, Fcall_process):
10902 Don't assume pid_t fits into an Emacs fixnum.

10911 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10912 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10913 (casify_object): Avoid integer overflow when overallocating buffer.
10914 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10915 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10916 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10917 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10918 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

10921 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10922 For CCL_MapSingle, check that content and value are in int range.
10923 (ccl_driver, Fregister_code_conversion_map):
10924 Check that Vcode_version_map_vector is a vector.
10925 (resolve_symbol_ccl_program): Check that vector header is in range.
10926 Always copy the vector, so that we can check its contents reliably
10927 now rather than having to recheck each instruction as it's being
10928 executed. Check that vector words fit in 'int'.
10929 (ccl_get_compiled_code, Fregister_ccl_program)
10930 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10931 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

10933 contents are in range.
10934 (Fccl_execute_on_string): Check that status is in range.
10935 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10936 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10937 Accept and return EMACS_INT, not int, because callers can pass values
10938 out of 'int' range.

10944 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10945 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10946 avoid mishandling large integers.

10955 Remove now-unnecessary CHECK_NATNUMs.
10956 (Fdefine_charset_internal): Check ranges here, more carefully.
10957 Don't rely on undefined behavior with signed left shift overflow.
10958 Don't assume unsigned int fits into fixnum, or that fixnum fits
10959 into unsigned int. Don't require max_code to be a valid fixnum;
10960 that's not true for gb10830 4-byte on a 32-bit host. Allow
10961 invalid_code to be a cons, for the same reason. Require code_offset
10962 to be a character. Avoid int overflow if max_char is close
10964 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10965 this is intended anyway and avoids some undefined behavior.
10966 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10967 INDEX_TO_CODE_POINT, as that's what it expects.
10968 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10969 * charset.h (DECODE_CHAR): Return int, not unsigned;
10970 this is what was intended anyway, and it avoids undefined behavior.
10971 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10972 integer-overflow issues.
10973 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10974 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10975 where the argument is EMACS_INT, and this behavior is not intended.
10976 * chartab.c (Fmake_char_table, Fset_char_table_range)
10977 (uniprop_get_decoder, uniprop_get_encoder):
10978 Don't assume fixnum fits in int.
10979 * cmds.c (move_point): New function, that does the gist of
10980 Fforward_char and Fbackward_char, but does so while checking
10981 for integer overflow more accurately.
10982 (Fforward_char, Fbackward_char): Use it.
10983 (Fforward_line, Fend_of_line, internal_self_insert)
10984 (internal_self_insert):
10985 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11644 2012-05-25 Glenn Morris <rgm@gnu.org>
11646 * lisp.mk (lisp): Update for more files being compiled now.
11648 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11650 * lread.c: Remove `read_pure' which makes no difference.
11651 (read_pure): Remove var.
11652 (unreadpure): Remove function.
11653 (readevalloop): Don't call read_list with -1 flag.
11654 (read1, read_vector): Don't test read_pure any more.
11655 (read_list): Simplify.

11666 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11668 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11671 This directory predates autoconf and is no longer needed nowadays.
11672 Move its few remaining bits of functionality to where they're needed.
11673 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
11674 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

11683 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11684 (BITS_PER_EMACS_INT): New constants, replacing
11685 what used to be in config.h, but not useful in #if.
11686 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11687 define them any more.
11688 (VAL_MAX): New macro.
11690 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11691 BITS_PER_EMACS_INT, in #if.
11692 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11693 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11694 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11695 * s/ms-w32.h (DATA_START):
11696 Move here from removed file m/intel386.h.
11697 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11698 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11700 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11702 Assume C89 or later.
11703 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11704 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11706 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

11723 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11725 2012-05-19 Ken Brown <kbrown@cornell.edu>
11727 * xfns.c (x_in_use): Remove `static' qualifier.
11728 * xterm.h (x_in_use): Declare.
11729 * xgselect.c: Include xterm.h.
11730 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11731 and `display_arg' (bug#9754).
11733 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11735 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11737 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11738 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11740 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11742 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11744 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11745 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11747 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11748 reference to image_cache->refcount.
11749 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11751 2012-05-17 Juri Linkov <juri@jurta.org>
11753 * search.c (Fword_search_regexp, Fword_search_backward)
11754 (Fword_search_forward, Fword_search_backward_lax)
11755 (Fword_search_forward_lax): Move functions to isearch.el
11756 (bug#10145, bug#11381).
11758 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11760 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11762 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11764 * lread.c (init_obarray): Declare Qt and Qnil as special.
11766 2012-05-14 Glenn Morris <rgm@gnu.org>
11768 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11769 Put "libexec" before "bin", for the sake of init_callproc_1.
11771 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11773 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11775 * unexaix.c: Port to more-recent AIX compilers.
11776 (report_error, report_error_1, make_hdr, copy_sym)
11777 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11778 Make arguments const char *, not char *, to avoid violations of C
11779 standard and to fix some AIX warnings reported by Gilles Pion.
11781 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11783 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11784 already have overlays loaded.
11785 (handle_single_display_spec): Before returning without displaying
11786 fringe bitmap, synchronize the bidi iterator with the main display
11787 iterator, by calling iterate_out_of_display_property.
11788 (iterate_out_of_display_property): Detect buffer iteration by
11789 testing that it->string is a Lisp string.
11790 (get_next_display_element): When the current object is exhausted,
11791 and there's something on it->stack, call set_iterator_to_next to
11792 proceed with what's on the stack, instead of returning zero.
11793 (set_iterator_to_next): If called at the end of a Lisp string,
11794 proceed to consider_string_end without incrementing string
11795 position. Don't increment display vector index past the end of
11796 the display vector. (Bug#11417)
11797 (pos_visible_p): Don't report a position visible when move_it_to
11798 stopped at the last line of window, which happens to be scanned
11799 backwards by the bidi iteration. (Bug#11464)
11801 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11803 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11804 and right-margin display specs even if the spec is invalid or we
11805 are on a TTY, and thus unable to display on the fringes.
11806 That's because the text with the property will not be displayed anyway,
11807 so we need to signal to the caller that this is a "replacing"
11808 display spec. This fixes display when the spec is invalid or we
11811 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11813 * unexaix.c (make_hdr): Fix typo in prototype.
11814 This bug broke the build on AIX. Problem reported by Gilles Pion.
11816 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11818 * keyboard.c (kbd_buffer_get_event): Read special events also in
11819 batch mode. (Bug#11415)
11821 2012-05-12 Glenn Morris <rgm@gnu.org>
11823 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11825 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11827 * lisp.mk (lisp): Add newcomment.elc.
11829 2012-05-12 Glenn Morris <rgm@gnu.org>
11831 * Makefile.in (MKDIR_P): New, set by configure.
11832 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11834 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11836 Remove unused function hourglass_started.
11837 * dispextern.h (hourglass_started):
11838 * w32fns.c (hourglass_started):
11839 * xdisp.c (hourglass_started): Remove.
11841 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11843 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11844 Update dependencies.
11846 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11848 * xgselect.c (xg_select): Put maxfds+1 into a var.
11849 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11851 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11853 2012-05-10 Dave Abrahams <dave@boostpro.com>
11855 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11856 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11858 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11860 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11861 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11862 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11863 Initialize xd_registered_buses.
11865 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11867 Untag more efficiently if USE_LSB_TAG.
11868 This is based on a proposal by YAMAMOTO Mitsuharu in
11869 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11870 For an admittedly artificial (nth 8000 longlist) benchmark on
11871 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11872 Emacs's overall text size by 1%.
11873 * lisp.h (XUNTAG): New macro.
11874 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11875 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11876 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11877 * eval.c (Fautoload):
11878 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11879 * frame.h (XFRAME): Use XUNTAG.
11881 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11882 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11883 Remove unportable assumptions about print widths of types like
11885 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11886 intptr_t when converting between pointer and integer, to avoid GCC
11887 warnings about wrong width.
11889 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11891 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11892 stack for each reader_thread, instead of defaulting to 8MB
11893 determined by the linker. This avoids failures in creating
11894 subprocesses on Windows 7, see the discussion in this thread:
11895 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11897 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11899 Fix up display of the *Minibuf-0* buffer in the mini window.
11900 * keyboard.c (read_char): Don't clear the echo area if there's no
11902 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11903 contents of *Minibuf-0*) if there's no message displayed in its stead.
11905 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11907 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11910 2012-05-06 Chong Yidong <cyd@gnu.org>
11912 * lisp.mk (lisp): Update.
11914 2012-05-05 Jim Meyering <meyering@redhat.com>
11916 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11918 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11920 * data.c (PUT_ERROR): New macro.
11921 (syms_of_data): Use it. Add new error type `user-error'.
11922 * undo.c (user_error): New function.
11923 (Fprimitive_undo): Use it.
11924 * print.c (print_error_message): Adjust print style for `user-error'.
11925 * keyboard.c (user_error): New function.
11926 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11928 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11930 Do not limit current-time-string to years 1000..9999.
11931 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11932 (Fcurrent_time_string): Support any year that is supported by the
11933 underlying localtime representation. Don't use asctime, as it
11934 has undefined behavior for years outside the range -999..9999.
11936 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11938 Fix race conditions involving setenv, gmtime, localtime, asctime.
11939 Without this fix, interrupts could mess up code that uses these
11940 nonreentrant functions, since setting TZ invalidates existing
11941 tm_zone or tzname values, and since most of these functions return
11942 pointers to static storage.
11943 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11944 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11945 Grow the critical sections to include not just invoking
11946 localtime/gmtime, but also accessing these functions' results
11947 including their tm_zone values if any, and any related TZ setting.
11948 (format_time_string): Last arg is now struct tm *, not struct tm **,
11949 so that the struct tm is saved in the critical section.
11950 All callers changed. Simplify allocation of initial buffer, partly
11951 motivated by the fact that memory allocation needs to be outside
11952 the critical section.
11954 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11956 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11957 with RESET_INTERVAL.

11968 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11970 * xdisp.c (pos_visible_p): If already at a newline from the
11971 display string before the 'while' loop, don't walk back the glyphs
11972 from it3.glyph_row. Solves assertion violation when the display
11973 string begins with a newline (egg.el). (Bug#11367)
11975 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>

11983 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11984 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11985 All were removed before 23.1.
11987 * dispnew.c: Remove HAVE_LIBNCURSES test;
11988 it is always true on relevant platforms.
11990 * Makefile.in (LD_SWITCH_X_SITE_RPATH):

12003 Do not avoid creating empty evaporating overlays (Bug#9642).
12004 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12005 That is, do not delete an evaporating overlay if it becomes
12006 empty after its bounds are adjusted to fit within its buffer.
12007 This fix caused other problems, and I'm reverting it until we get
12008 to the bottom of them.
12010 2012-04-27 Chong Yidong <cyd@gnu.org>
12012 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12014 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12016 * xdisp.c (pos_visible_p): If the window start position is beyond
12017 ZV, start the display from buffer beginning. Prevents assertion
12018 violation in init_iterator when the minibuffer window is scrolled
12019 via the scroll bar.
12021 * window.c (window_scroll_pixel_based): Likewise.
12023 2012-04-27 Chong Yidong <cyd@gnu.org>

12032 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12034 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12035 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12037 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12039 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12040 display element, check also the underlying string or buffer
12041 character. (Bug#11341)
12043 * w32menu.c: Include w32heap.h.
12044 (add_menu_item): If the call to AppendMenuW (via
12045 unicode_append_menu) fails, disable Unicode menus only if we are
12046 running on Windows 9X/Me.
12048 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12050 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12051 (xgetint): Add missing shift for LSB tags.
12053 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12055 * keyboard.c (read_char): Don't wipe echo area for select window
12056 events: These might get delayed via `mouse-autoselect-window'

12061 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12062 manipulation of :loaded-from data.
12064 2012-04-23 Juanma Barranquero <lekktu@gmail.com>

12067 now a cons (bug#11311).
12069 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12071 Do not create empty overlays with the evaporate property (Bug#9642).
12072 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12073 if it becomes empty after its bounds are adjusted to fit within
12074 its buffer. Without this fix, in a nonempty buffer (let ((o
12075 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12076 yields an empty overlay that has the evaporate property, which is
12077 not supposed to happen.

12194 * sysdep.c [__FreeBSD__]: Minor cleanups.
12195 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12196 Use Emacs indenting style more consistently. Avoid some casts.

12211 It is never used otherwise.
12213 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12215 * print.c (print_preprocess): Only check print_depth if print-circle

12282 (NEED_MEM_INSERT): New macro.
12283 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.

12386 Pass EMACS rather than BUILT_EMACS.
12388 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12390 * process.c (make_process):
12391 * process.h: Add integer `gnutls_handshakes_tried' member to
12394 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
12395 Add convenience `GNUTLS_LOG2i' macro.
12397 * gnutls.c (gnutls_log_function2i): Convenience log function.
12398 (emacs_gnutls_read): Use new log functions,
12399 `gnutls_handshakes_tried' process member, and
12400 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12401 attempts per process (connection).
12403 2012-04-09 Chong Yidong <cyd@gnu.org>
12405 * eval.c (Fuser_variable_p, user_variable_p_eh)
12406 (lisp_indirect_variable): Functions deleted.
12407 (Fdefvar): Caller changed.
12409 * callint.c (Finteractive, Fcall_interactively):
12410 * minibuf.c (Fread_variable): Callers changed.
12412 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12414 * xdisp.c (set_cursor_from_row): If the display string appears in
12415 the buffer at position that is closer to point than the position
12416 after the display string, display the cursor on the first glyph of
12417 the display string. Fixes cursor display when a 'display' text
12418 property immediately follows invisible text. (Bug#11094)
12420 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12422 composite.c: use 'double' consistently
12423 * composite.c (get_composition_id): Use 'double' consistently
12424 instead of converting 'float' to 'double' and vice versa; this is
12425 easier to understand and avoids a GCC warning.
12427 2012-04-09 Glenn Morris <rgm@gnu.org>
12429 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12430 preparation for dumping it with emacs. (Bug#4789)
12431 (leimdir): New variable.
12432 ($(leimdir)/leim-list.el): New rule.
12433 (emacs$(EXEEXT)): Depend on leim-list.el.

12449 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12451 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12452 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12453 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12454 objects, as mark_maybe_pointer will catch them otherwise.
12455 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12456 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
12458 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12460 Fix typo that broke non-Windows builds.
12461 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
12463 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12465 Support building on MS-Windows with libxml2.
12467 * makefile.w32-in (OBJ2): Add xml.$(O).
12468 (GLOBAL_SOURCES): Add xml.c.
12469 ($(BLD)/xml.$(O)): New dependency list.
12471 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12472 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12473 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12474 [!WINDOWSNT]: New macros.
12475 (init_libxml2_functions, libxml2_loaded_p): New functions.
12476 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12477 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12478 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12479 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12481 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12482 Call init_libxml2_functions before calling libxml2 functions.
12483 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12485 * emacs.c: Don't include libxml/parser.h.
12486 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12487 xmlCleanupParser directly.
12489 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12491 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12493 * indent.c (Fvertical_motion): If there is a display string at
12494 point, use it.vpos to compute how many lines to backtrack after
12495 move_it_to point. (Bug#11133)
12497 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12499 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12500 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12501 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12502 macros related to unification of CJK characters. For the details,
12503 see the discussion following the message here:
12504 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12506 2012-04-04 Chong Yidong <cyd@gnu.org>
12508 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12510 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12512 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12513 instead of alloca. (Bug#11138)
12515 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12517 * w32menu.c (is_simple_dialog): Properly check lisp types.
12520 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12522 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12523 position we get to after a call to move_it_to fails the
12524 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12525 only if we wind up in a string from display property. (Bug#11063)
12527 * window.c (Fdelete_other_windows_internal): Invalidate the row
12528 and column information about mouse highlight, so that redisplay
12529 restores it after reallocating the glyph matrices. (Bug#7464)
12531 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12532 string comes from a `display' text property, use the buffer
12533 position of that property as if we actually saw that position in
12535 (move_it_by_lines): Remove the assertion that
12536 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12537 violated when there's a before-string at the beginning of a line.
12540 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12542 * xdisp.c (append_space_for_newline): If the default face was
12543 remapped, use the remapped face for the appended newline.
12544 (extend_face_to_end_of_line): Use the remapped default face for
12545 extending the face to the end of the line.
12546 (display_line): Call extend_face_to_end_of_line when the default
12547 face was remapped. (Bug#11068)
12549 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12551 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12553 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12555 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12557 2012-03-27 Glenn Morris <rgm@gnu.org>
12559 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12562 2012-03-26 Kenichi Handa <handa@m17n.org>
12564 * dispextern.h (struct glyph): Fix previous change. Change the
12565 bit length of glyphless.ch to 25 (Bug#11082).
12567 2012-03-26 Chong Yidong <cyd@gnu.org>
12569 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12570 (command_loop_1): Use it; inhibit selection update for
12571 handle-select-window too (Bug#8996).
12573 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12575 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12577 2012-03-25 Kenichi Handa <handa@m17n.org>
12579 * dispextern.h (struct glyph): Change the bit length of
12580 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12582 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12584 * s/ms-w32.h (tzname): Include time.h before redirecting to
12585 _tzname. Fixes the MSVC build. (Bug#9960)
12587 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12589 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12592 * xterm.c (XTread_socket): Only modify handling_signal if
12593 !SYNC_INPUT. (Bug#11080)
12595 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12597 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12598 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12599 when fetching a multibyte character consumes more bytes than
12600 CHAR_BYTES returns, due to unification of CJK characters in
12601 string_char. (Bug#11073)
12603 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12605 * process.c (wait_reading_process_output): Handle pty disconnect
12606 by refraining from sending oneself a SIGCHLD (bug#10933).
12608 2012-03-22 Chong Yidong <cyd@gnu.org>

12613 Mark string as coming from a prefix property.
12614 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12615 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12617 2012-03-21 Chong Yidong <cyd@gnu.org>
12619 * xfaces.c (Vface_remapping_alist): Doc fix.
12621 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12623 * w32proc.c (Fw32_set_console_codepage)
12624 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12627 2012-03-20 Chong Yidong <cyd@gnu.org>
12629 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12630 to reflect default non-nil value of redisplay-dont-pause.
12632 2012-03-19 Kenichi Handa <handa@m17n.org>
12634 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12635 it fit in a valid range (Bug#11003).
12637 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12639 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12640 that is not from display property, accept the row as a "cursor
12641 row" if one of the string's character has a non-nil `cursor'
12642 property. Fixes cursor positioning when there are newlines in
12643 overlay strings, e.g. in icomplete.el. (Bug#11035)
12645 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12647 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12649 2012-03-12 Chong Yidong <cyd@gnu.org>
12651 * eval.c (inhibit_lisp_code): Rename from
12652 inhibit_window_configuration_change_hook; move from window.c.
12654 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12655 * window.c (run_window_configuration_change_hook)
12656 (syms_of_window): Callers changed.

12667 is visible (Bug#10955).
12669 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12671 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

12675 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12676 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12679 2012-03-03 Glenn Morris <rgm@gnu.org>
12681 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12683 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12685 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12686 position past the first glyph_row that ends at ZV. (Bug#10902)
12687 (redisplay_window, next_element_from_string): Fix typos in
12689 (redisplay_window): Pass to move_it_vertically the margin in
12690 pixels, not in screen lines.
12692 2012-03-02 Glenn Morris <rgm@gnu.org>
12694 * buffer.c (buffer-list-update-hook): Doc fix.
12696 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12698 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12699 push_it before setting up the iterator for the first overlay
12700 string, even if we have an empty string loaded.
12701 (next_overlay_string): If there's an empty string on the iterator
12702 stack, pop the stack. (Bug#10903)
12704 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12706 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12707 Suggested by Stefan Monnier in
12708 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12709 * alloc.c (widen_to_Lisp_Object): New static function.
12710 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12711 and widening them to Lisp_Objects. This would work even if
12712 USE_LSB_TAG is defined and wide integers are used, which might
12713 happen in a future version of Emacs.
12715 2012-02-25 Chong Yidong <cyd@gnu.org>
12717 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12720 * xselect.c (Fx_selection_exists_p): Doc fix.
12721 (x_clipboard_manager_save_all): Print an informative message
12722 before saving to clipboard manager.
12724 2012-02-24 Chong Yidong <cyd@gnu.org>
12726 * keyboard.c (process_special_events): Handle all X selection
12727 requests in kbd_buffer, not just the next one (Bug#8869).
12729 2012-02-23 Chong Yidong <cyd@gnu.org>
12731 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12732 call when setting menu-bar-lines and tool-bar-lines parameters.
12733 (unwind_create_frame_1): New helper function.
12735 * window.c (inhibit_window_configuration_change_hook): New var.
12736 (run_window_configuration_change_hook): Obey it.

12754 when computing $valmask.
12756 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12757 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12758 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12759 It's useless in that case, and it can cause problems on hosts
12760 that allocate halves of EMACS_INT values separately.
12761 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12762 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12763 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12764 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12765 it avoids undefined behavior on hosts where shifting right by more
12766 than the word width has undefined behavior.
12768 2012-02-19 Chong Yidong <cyd@gnu.org>
12770 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12771 (Funhandled_file_name_directory, Ffile_name_as_directory)
12772 (Fdirectory_file_name, Fexpand_file_name)
12773 (Fsubstitute_in_file_name): Protect against invalid file handler
12774 return values (Bug#10845).
12776 2012-02-18 Eli Zaretskii <eliz@gnu.org>
12778 * .gdbinit (pitx): Fix incorrect references to fields of the

12785 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
12787 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
12788 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12790 2012-02-15 Chong Yidong <cyd@gnu.org>
12792 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12793 marked as special. Also, starting docstrings with * is obsolete.

12806 * keymap.c (Fsingle_key_description): Handle char ranges.
12808 2012-02-12 Chong Yidong <cyd@gnu.org>
12810 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12811 as that creates a dangerous corner case.
12813 * window.c (Fdelete_window_internal): Invalidate the mouse
12814 highlight (Bug#9904).
12816 2012-02-12 Glenn Morris <rgm@gnu.org>
12818 * xselect.c (Fx_own_selection_internal)
12819 (Fx_get_selection_internal, Fx_disown_selection_internal)
12820 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12821 * nsselect.m (Fx_own_selection_internal)
12822 (Fx_disown_selection_internal, Fx_selection_exists_p)
12823 (Fx_selection_owner_p, Fx_get_selection_internal):
12824 Sync docs and argument specs with the xselect.c versions.
12826 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12828 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
12830 2012-02-11 Eli Zaretskii <eliz@gnu.org>
12832 * w32select.c (Fx_selection_exists_p): Sync doc string and
12833 argument list with xselect.c. (Bug#10783)
12835 * w16select.c (Fx_selection_exists_p): Sync doc string and
12836 argument list with xselect.c. (Bug#10783)

12846 2012-02-07 Chong Yidong <cyd@gnu.org>
12848 * buffer.c (Fbuffer_local_variables)
12849 (buffer_lisp_local_variables): Handle unbound vars correctly;
12850 don't let Qunbound leak into Lisp.
12852 2012-02-07 Glenn Morris <rgm@gnu.org>
12854 * image.c (Fimagemagick_types): Doc fix.
12856 * image.c (imagemagick-render-type): Change it from a lisp object
12857 to an integer. Move the doc here from the lisp manual.
12858 Treat all values not equal to 0 the same.
12860 2012-02-06 Chong Yidong <cyd@gnu.org>
12862 * doc.c (store_function_docstring): Avoid applying docstring of

13369 2011-12-01 Stefan Monnier <monnier@iro.umontreal.ca>
13371 * fileio.c (Finsert_file_contents): Move after-change-function call
13372 to before the "handled:" label, since all "goto handled" appear in
13373 cases where the *-change-functions have already been properly called
13376 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
13378 * keyboard.c (interrupt_signal): Don't call kill-emacs when

13383 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13384 verifies glyph row's hash code--we have just reallocated the
13385 glyphs, so their contents can be complete garbage. (Bug#10164)

13431 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13432 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13433 this macro definition.
13435 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

13460 * xdisp.c (redisplay_window): If cursor row is not fully visible
13461 after recentering, and scroll-conservatively is set to a large
13462 number, scroll window by a few more lines to make the cursor fully
13463 visible and out of scroll-margin. (Bug#10105)
13464 (start_display): Don't move to the next line if the display should
13465 start at a newline that is part of a display vector or an overlay
13466 string. (Bug#10119)

13545 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13546 Otherwise, valgrind does not work on some platforms.
13547 Problem reported by Andreas Schwab in
13548 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13549 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13550 is set, removing the need for VIRT_ADDRESS_VARIES.
13551 (PURE_P): Use a more-efficient implementation that needs just one
13552 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13553 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13554 to 4 (xorl, subq, cmpq, setbe).
13555 * alloc.c (pure): Always extern now, since that's the
13556 VIRT_ADDR_VARIES behavior.
13557 (PURE_POINTER_P): Use a single comparison, not two, for
13558 consistency with the new puresize.h.
13559 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13560 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13566 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13567 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13568 behave as if the cursor position were at the window margin.
13570 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13571 and the cursor position is out of bounds, behave as if the cursor
13572 position were at the window margin. (Bug#10075)
13574 2011-11-18 Chong Yidong <cyd@gnu.org>
13576 * window.c (Fwindow_combination_limit): Make first argument

13595 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13597 * xdisp.c (row_hash): New function, body extracted from
13598 compute_line_metrics.
13599 (compute_line_metrics): Call row_hash, instead of computing the
13602 * dispnew.c (verify_row_hash): Call row_hash for computing the
13603 hash code of a row, instead of duplicating code from xdisp.c.
13605 * dispextern.h (row_hash): Add prototype.
13607 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13609 * frame.c (delete_frame): Don't delete the terminal when the last

13635 (Fsplit_window_internal, saved_window)
13636 (Fset_window_configuration, save_window_save): Rename all
13637 occurrences of window_nest to window_combination_limit.

13643 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13645 * xdisp.c (display_line): Move the call to
13646 highlight_trailing_whitespace before the call to
13647 compute_line_metrics, since the latter needs to see the final
13648 faces of all the glyphs to compute ROW's hash value.
13649 Fixes assertion violations in row_equal_p. (Bug#10035)
13651 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13653 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13654 just return (bug#10044).

13658 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13659 with user-defined heap size. Bump the default size of the temacs
13660 heap to 27MB, to avoid memory warning when running temacs.
13661 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13663 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13664 current_matrix and desired_matrix. (Bug#9990)
13665 (verify_row_hash) [XASSERTS]: New function.
13666 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

13710 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13712 Avoid some portability problems by eschewing 'extern inline' functions.
13713 The trivial performance wins aren't worth the portability hassles; see
13714 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13716 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13717 (window_box_width, window_box_left, window_box_left_offset)
13718 (window_box_right, window_box_right_offset): Undo previous change,
13719 by removing the "extern"s.
13720 * intervals.c (adjust_intervals_for_insertion)
13721 (adjust_intervals_for_deletion): Undo previous change,
13722 making these static again.

13790 (window_box_width, window_box_left, window_box_left_offset)
13791 (window_box_right, window_box_right_offset): Declare extern.
13792 Otherwise, these inline functions do not conform to C99 and
13793 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13794 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13795 * intervals.c (adjust_intervals_for_insertion)

13797 extern inline functions 'offset_intervals' couldn't refer to it.
13798 (static_offset_intervals): Remove.
13799 (offset_intervals): Rewrite using the old contents of
13800 static_offset_intervals. The old version didn't conform to C99

14106 (bidi_resolve_weak): Don't enter the expensive loop if the current
14107 position is before next_en_pos. Record the bidi type of the first
14108 non-ET, non-BN character we find, in addition to its position.
14109 (bidi_level_of_next_char): Invalidate next_en_type when
14110 next_en_pos is over-stepped.
14112 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14114 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14115 * editfns.c: Rewrite current-time-zone so that it invokes
14116 the equivalent of (format-time-string "%Z") to get the time zone name.
14117 This fixes a bug when the time zone name contains characters that
14118 need converting from the system time locale to Emacs internal format.
14119 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14120 that patch fixed format-time-string to do the conversion, but
14121 I forgot to fix current-time-zone.
14122 (format_time_string): New function, containing most of
14123 what Fformat_time_string used to contain.
14124 (Fformat_time_string): Rewrite in terms of format_time_string.
14125 This doesn't change this function's behavior.
14126 (current-time-zone): Rewrite to use format_time_string.
14127 This fixes the bug reported by Michael Schierl in
14128 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14129 Jason Rumney's 2007-06-07 change worked around this bug, but
14131 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14133 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14135 * xdisp.c (start_display): If the character at POS is displayed
14136 via a display vector, reset IT->current.dpvec_index to zero.
14137 (try_window_reusing_current_matrix): If a line ends in a display
14138 vector or the next line starts in a display vector, continue
14139 redrawing the window even though the character position of
14140 start_row was reached.
14143 2011-10-18 Chong Yidong <cyd@gnu.org>
14145 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14146 with nobreak-char-display too.
14148 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14150 Fix part 3 of bug#9771.
14151 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14152 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14153 non-neutral characters if the current character is a paragraph
14154 separator (a.k.a. Newline). This avoids running the same
14155 expensive loop twice, once when we consume the preceding newline
14156 and the other time when the line actually needs to be displayed.
14157 Avoid the loop when we see neutrals on the base embedding level
14158 following a character whose directionality is the same as the
14159 paragraph's. This avoids running the expensive loop when a line
14160 ends in a long sequence of neutrals, like control characters.
14161 Add assertion against STRONG_AL type. Slightly rearrange code
14162 that determines the type of a neutral given the first non-neutral
14164 (bidi_level_of_next_char): Set next_en_pos to zero when
14165 invalidating its info.
14167 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14169 * xdisp.c (push_display_prop): Determine whether to record string
14170 or buffer position by IT->string, not by IT->method. Allow
14171 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14172 (move_it_vertically_backward): Don't look for character position
14173 immediately after the newline when in a continuation line.
14176 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14178 * window.c (coordinates_in_window): Rewrite and delabelize
14179 vertical border check. (Bug#5357) (Bug#9618)

14189 avoid crash when xmalloc overrun checking is enabled.
14191 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14193 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14194 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14195 cursor motion with <left> and <right> arrow keys.
14197 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14198 some callers set that themselves.
14200 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14202 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14203 display string and the previous row comes from the same string and
14204 is empty. (Bug#9739) (Bug#9738)
14206 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14208 * doc.c (get_doc_string): Encode file name (bug#9735).
14210 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14212 * bidi.c (bidi_level_of_next_char):
14213 * xdisp.c (get_visually_first_element): Remove old incorrect
14214 comments regarding the Unicode Line Separator character.
14216 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.

14227 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14229 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14230 Some packages use them to denote characters with modifiers.
14232 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14234 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14235 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14236 matching a pp-number. Rename parameter var to var1.

14259 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14260 Don't advertise functionality which we discourage or doesn't work.
14262 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14264 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14265 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14266 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14267 this makes Emacs dump core during garbage collection on rare
14268 occasions. sizeof is obviously inferior to offsetof here, so
14269 stick with offsetof.
14270 (GC_POINTER_ALIGNMENT): New macro.
14271 (mark_memory): Omit 3rd (offset) arg; caller changed.
14272 Don't assume EMACS_INT alignment is the same as pointer alignment.
14274 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14276 * keyboard.c (read_key_sequence_remapped): New var.
14277 (read_key_sequence): Compute remapping in the right buffer.
14278 (command_loop_1): Use read_key_sequence's remapping directly.
14280 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14282 * dired.c (file_name_completion): Don't expand file name.
14283 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14284 before checking file name handler.
14286 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14287 they've been requested explicitly (bug#9591).
14289 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14291 * keymap.c (Fsingle_key_description): Use make_specified_string
14292 instead of build_string to build string from push_key_description.
14295 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14297 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14298 This fixes a Y2038 bug on 64-bit hosts.
14299 * buffer.c (reset_buffer):
14300 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14301 (Fclear_buffer_auto_save_failure):
14302 Use 0, not -1, to represent an unset failure time, since time_t
14303 might not be signed.
14305 Remove dependency on glibc malloc internals.
14306 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14307 Move back here from lisp.h, but with their new implementations.
14308 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14309 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14310 * charset.c (charset_table_init): New static var.
14311 (syms_of_charset): Use it instead of xmalloc. This removes a
14312 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14313 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14314 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14315 Move back to alloc.c.
14316 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14317 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14319 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14321 * nsterm.m (windowDidResize): Call x_set_window_size only when
14322 ns_in_resize is true. Otherwise set pixelwidth/height and
14323 call change_frame_size (Bug#9628).
14325 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14327 Port --enable-checking=all to Fedora 14 x86-64.
14328 * charset.c (syms_of_charset): Also account for glibc malloc's
14329 internal overhead when calculating the initial malloc maximum.
14331 Port --enable-checking=all to Fedora 14 x86.
14332 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14334 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14335 (overrun_check_realloc, overrun_check_free):
14336 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14337 That way, xmalloc returns a properly-aligned pointer even if
14338 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14339 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14340 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14341 into account when calculating the initial malloc maximum.
14342 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14343 Move here from alloc.c, so that charset.c can use it too.
14344 Properly align; the old code wasn't right for common 32-bit hosts
14345 when configured with --enable-checking=all.
14346 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14347 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14349 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14351 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14354 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14356 * xdisp.c (compute_display_string_end): If there's no display
14357 string at CHARPOS, return -1.
14359 * bidi.c (bidi_fetch_char): When compute_display_string_end
14360 returns a negative value, treat the character as a normal
14361 character not covered by a display string. (Bug#9624)
14363 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14365 * lread.c (Fread_from_string): Fix typo in docstring.
14367 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14369 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14370 newline, reseat the iterator instead of bidi-iterating there one
14371 character at a time. (Bug#9610)
14372 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14373 TO_CHARPOS if the bidi iterator is at base embedding level.
14375 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14377 * lread.c (readevalloop): Use correct code for NBSP.
14378 (read1): Likewise. (Bug#9608)
14380 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14382 * dbusbind.c (Fdbus_register_signal): When service is not
14383 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14385 2011-09-25 Glenn Morris <rgm@gnu.org>
14387 * buffer.c (truncate-lines): Doc fix.
14389 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14391 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14392 (Fset_window_next_buffers): Doc fix.
14394 2011-09-24 Glenn Morris <rgm@gnu.org>
14396 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14398 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14400 Fix minor problems found by static checking.
14401 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14402 * indent.c (Fvertical_motion): Fix == vs = typo.
14404 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14406 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14407 Default value is now t. Doc fix.
14409 * indent.c (Fvertical_motion): Compute and apply the overshoot
14410 logic when moving up, not only when moving down. Fix the
14411 confusing name and values of the it_overshoot_expected variable;
14412 logic changes accordingly. (Bug#9254) (Bug#9549)
14414 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14415 CHARPOS is covered by a display string which includes newlines.
14416 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14417 is covered by a display string with embedded newlines.
14419 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14421 * dbusbind.c (Fdbus_register_signal): Add match rule to
14422 Vdbus_registered_objects_table. (Bug#9581)
14423 (Fdbus_register_method, Vdbus_registered_objects_table):
14426 2011-09-24 Jim Meyering <meyering@redhat.com>
14428 do not ignore write error for any output size
14429 The previous change was incomplete.
14430 While it makes emacs --batch detect the vast majority of stdout
14431 write failures, errors were still ignored whenever the output size is
14432 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14433 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14434 && echo FAIL: ignored write error
14435 FAIL: ignored write error
14436 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14437 && echo FAIL: ignored write error
14438 FAIL: ignored write error
14439 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14441 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14443 * emacs.c (Fkill_emacs): In noninteractive mode exit
14444 non-successfully if a write error occurred on stdout. (Bug#9574)
14446 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14448 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14451 * dispextern.h (struct it): Update the comment documenting what
14454 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14456 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14457 a display string, extend search for cursor position to end of row.
14458 (find_row_edges): If the row ends in a newline from a display
14459 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14460 Handle the case of a display string with multiple newlines.
14461 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14462 non-empty line. Fixes confusing cursor motion with arrow keys at
14463 the beginning of a line that starts with whitespace.
14465 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14467 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14470 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14472 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14473 boolean (Bug#9154).
14475 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14477 * xdisp.c (display_line): Record maximum and minimum buffer
14478 positions even if no glyphs were produced (e.g., by a zero-width
14479 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14480 buffer positions that will be removed from the glyph row because
14482 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14483 column is beyond frame width: don't subtract 1 "pixel" when
14484 computing width of the stretch.
14485 (reseat_at_next_visible_line_start): Undo the change made on
14486 2011-09-17 that saved paragraph information and restored it after
14487 the call to `reseat'. (Bug#9545)
14489 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14491 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14492 and turn window cursor on if cleared (Bug#9415).
14494 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14496 * search.c (boyer_moore): Take unibyte characters from pattern
14497 literally. (Bug#9458)
14499 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14501 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14503 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14505 Fix minor problem found by static checking.
14506 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14507 initialized, to pacify gcc -Wuninitialized.
14509 * fileio.c: Report proper errno when syscall falls.
14510 (Finsert_file_contents): Save and restore errno,
14511 so that report_file_error outputs the correct diagnostic.
14512 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14514 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14516 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14518 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14520 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14521 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14523 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14525 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14526 about the current paragraph and restore it after the call to reseat.
14528 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14529 (bidi_find_paragraph_start): Search back for paragraph beginning
14530 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14531 (bidi_move_to_visually_next): Only trigger paragraph-related
14532 computations when the last character is a newline or at EOB, not
14533 just any NEUTRAL_B. (Bug#9470)
14535 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14536 truncated lines if point is covered by a display string. (Bug#9524)
14538 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14540 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14541 (cons_to_x_long): New function.
14542 (lisp_data_to_selection_data): Use it. Correct the test for
14543 short-versus-long data; it was negated. Break out of vector
14544 loop, for efficiency, when a long datum is discovered.
14546 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14548 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14550 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14552 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14553 GCC PR/17406) by declaring this function with external scope.
14555 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14557 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14558 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14560 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14562 * editfns.c (Fformat): Correctly handle text properties on "%%".
14564 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14566 * xterm.c (x_draw_composite_glyph_string_foreground):
14567 * w32term.c (x_draw_composite_glyph_string_foreground):
14568 * term.c (encode_terminal_code):
14569 * composite.c (composition_update_it, get_composition_id):
14570 * xdisp.c (get_next_display_element)
14571 (fill_composite_glyph_string): Add comments about special meaning
14572 of TAB characters in a composition.
14574 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14576 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14577 This occurs when processing a multibyte format.
14578 Problem reported by Wolfgang Jenker.
14580 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14582 * xdisp.c (try_cursor_movement): Only check for exact match if
14583 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14585 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14587 Remove unused external symbols.
14588 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14589 * xdisp.c (calc_pixel_width_or_height): Now static.
14590 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14591 * indent.c (check_display_width):
14592 * w32term.c: Fix comment to match code.
14593 * xterm.c, xterm.h (x_catching_errors): Remove.
14595 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14597 * xselect.c: Use signed conversions more consistently (Bug#9498).
14598 (selection_data_to_lisp_data): Assume incoming selection data are
14599 signed integers, not unsigned. This is to be consistent with
14600 outgoing selection data, which was modified to use signed integers
14601 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14602 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14603 expects long, not unsigned long.
14605 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14607 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14608 computation of loop end. Reported by Johan Bockgård
14611 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14613 * frame.c (Fother_visible_frames_p): Function deleted.
14615 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14617 * indent.c (compute_motion): Process display vector front to back
14618 rather than the other way around. (Bug#2496)
14620 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14622 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14624 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14626 * minibuf.c (Fread_from_minibuffer): Doc fix.
14628 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14630 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14631 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14633 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14635 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14636 value for non-existent files.
14638 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14640 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14641 set its "size" to -1. This will set the modtime_size field of
14642 the corresponding buffer to -1, which is what
14643 verify-visited-file-modtime expects for files that do not exist.
14646 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14648 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14650 * lisp.h: ... from here. push_key_description is no longer
14651 defined in keyboard.c, so its declaration should not be in
14652 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14653 logically belongs with push_key_description.
14655 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14657 * buffer.h: Include <sys/types.h> instead of <time.h>.
14658 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14659 Problem reported by Herbert J. Skuhra.
14661 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14663 * xml.c (parse_region): Make the parsing work for
14664 non-comment-starting XML files again (bug#9144).
14666 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14668 * image.c (gif_load): Fix calculation of bottom and right corner.
14671 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14673 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14674 redisplay in small windows.
14676 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14678 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14680 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14682 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14683 Operate on live windows only.
14685 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14687 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14689 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14691 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14692 only under bidi iteration.
14694 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14696 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14698 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14700 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14701 Without this fix, the command to link temacs failed due to an
14702 undefined symbol __builtin_isnan. This is because
14703 /usr/include/iso/math_c99.h #defines isnan(x) to
14704 __builtin_isnan(x), but the bundled gcc, which identifies itself
14705 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14707 * floatfns.c (isnan): #undef, and then #define to a clone of
14709 (Fisnan): Always define, since it's always available now.
14710 (syms_of_floatfns): Always define isnan at the Lisp level.
14712 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14714 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14716 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14718 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14719 The previous code assumed that file offsets (off_t values) fit in
14720 EMACS_INT variables, which is not true on typical 32-bit hosts.
14721 The code messed up by falsely reporting buffer overflow in cases
14722 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14723 when "big" contains more than 2**29 bytes, even though this
14724 inserts just one byte and does not overflow the buffer.
14725 (Finsert_file_contents): Store file offsets as off_t
14726 values, not as EMACS_INT values. Check for overflow when
14727 converting between EMACS_INT and off_t. When checking for
14728 buffer overflow or for overlap, take the offsets into account.
14729 Don't use EMACS_INT for small values where int suffices.
14730 When checking for overlap, fix a typo: ZV was used where
14731 ZV_BYTE was intended.
14732 (Fwrite_region): Don't assume off_t fits into 'long'.
14733 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14735 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14737 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14739 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14741 sprintf-related integer and memory overflow issues (Bug#9412).
14743 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14744 (esprintf, exprintf, evxprintf): New functions.
14745 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14746 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14747 (modify_event_symbol): Do not assume that the length of
14748 name_alist_or_stem is safe to alloca and fits in int.
14749 (Fexecute_extended_command): Likewise for function name and binding.
14750 (Frecursion_depth): Wrap around reliably on integer overflow.
14751 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14752 since some callers pass EMACS_INT values.
14753 (Fsingle_key_description): Don't crash if symbol name contains more
14754 than MAX_ALLOCA bytes.
14755 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14756 (get_minibuffer): Arg is now EMACS_INT, not int.
14757 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14758 (esprintf, exprintf, evxprintf): New decls.
14759 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14761 * dbusbind.c (signature_cat): New function.
14762 (xd_signature, Fdbus_register_signal):
14763 Do not overrun buffer; instead, report string overflow.
14765 * dispnew.c (add_window_display_history): Don't overrun buffer.
14766 Truncate instead; this is OK since it's just a log.
14768 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14769 even if the time zone offset is outlandishly large.
14770 Don't mishandle offset == INT_MIN.
14772 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14773 when creating daemon; the previous buffer-overflow check was incorrect.
14775 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14776 which has the guts of the old verror function.
14778 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14779 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14781 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14782 (font_unparse_xlfd): Don't blindly alloca long strings.
14783 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14784 fits in int, when using sprintf. Use single snprintf to count
14785 length of string rather than counting it via multiple sprintfs;
14786 that's simpler and more reliable.
14787 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14788 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14789 sprintf, in case result does not fit in int.
14791 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14792 (fontset_from_font): Print it.
14794 * frame.c (tty_frame_count): Now printmax_t, not int.
14795 (make_terminal_frame, set_term_frame_name): Print it.
14796 (x_report_frame_params): In X, window IDs are unsigned long,
14797 not signed long, so print them as unsigned.
14798 (validate_x_resource_name): Check for implausibly long names,
14799 and don't assume name length fits in 'int'.
14800 (x_get_resource_string): Don't blindly alloca invocation name;
14801 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14804 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14805 (xg_check_special_colors, xg_set_geometry):
14806 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14808 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14809 Use esprintf, not sprintf, in case result does not fit in int.
14811 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14812 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14813 it as a large positive number.
14814 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14815 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14817 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14818 in case result does not fit in int.
14820 * print.c (float_to_string): Detect width overflow more reliably.
14821 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14822 buffer overrun. Don't assume list length fits in 'int'. Treat
14823 print length of 0 as 0, not as infinity; to be consistent with other
14824 uses of print length in this function. Don't overflow print length
14825 index. Don't assume hash table size fits in 'long', or that
14826 vectorlike size fits in 'unsigned long'.
14828 * process.c (make_process): Use printmax_t, not int, to format
14829 process-name gensyms.
14831 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14833 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14834 to avoid potential buffer overrun.
14836 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14837 if X resource line is longer than 512 bytes.
14839 * xfns.c (x_window): Make sprintf buffer a bit bigger
14840 to avoid potential buffer overrun.
14842 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14844 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14846 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14848 Integer overflow fixes for scrolling, etc.
14849 Without these, Emacs silently mishandles large integers sometimes.
14850 For example, "C-u 4294967297 M-x recenter" was treated as if
14851 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14853 * xdisp.c (try_window_id): Check Emacs fixnum range before
14854 converting to 'int'.
14856 * window.c (window_scroll_line_based, Frecenter):
14857 Check that an Emacs fixnum is in range before assigning it to 'int'.
14858 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14859 values converted from Emacs fixnums.
14860 (Frecenter): Don't wrap around a line count if it is out of 'int'
14861 range; instead, treat it as an extreme value.
14862 (Fset_window_configuration, compare_window_configurations):
14863 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14865 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14866 that can exceed INT_MAX. Check that EMACS_INT value is in range
14867 before assigning it to the (possibly-narrower) index.
14868 (match_limit): Don't assume that a fixnum can fit in 'int'.
14870 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14873 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14874 (Fvertical_motion): Don't wrap around LINES values that don't fit
14875 in 'int'. Instead, treat them as extreme values. This is good
14876 enough for windows, which can't have more than INT_MAX lines anyway.
14878 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14880 * Require libxml/parser.h to avoid compilation warning.
14882 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14884 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14885 since this reportedly can destroy thread storage.
14887 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14889 * syntax.c (find_defun_start): Update all cache variables if
14890 exiting early (Bug#9401).
14892 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14894 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14896 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14897 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14898 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14900 * term.c (tty_append_glyph): New function.
14901 (produce_stretch_glyph): Static function and its prototype deleted.
14903 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14906 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14908 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14909 when checking :margin (Bug#9390).
14910 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14911 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14912 so that the name doesn't mislead. All uses changed.
14914 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14916 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14919 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14921 * xdisp.c (move_it_to): Don't bail out early when reaching
14922 position beyond to_charpos, if we are scanning backwards.
14923 (move_it_vertically_backward): When DY == 0, make sure we get to
14924 the first character in the line after the newline.
14926 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14928 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14929 (ccl_driver): Do not generate an out-of-range pointer.
14930 (Fccl_execute_on_string): Remove unnecessary check for
14931 integer overflow, noted by Stefan Monnier in
14932 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14933 Remove a FIXME that didn't need fixing.
14934 Simplify the newly-introduced buffer reallocation code.
14936 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14938 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14940 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14942 Integer and memory overflow issues (Bug#9196).
14944 * doc.c (get_doc_string): Rework so that
14945 get_doc_string_buffer_size is the actual buffer size, rather than
14946 being 1 less than the actual buffer size; this makes xpalloc more
14949 * image.c (x_allocate_bitmap_record, cache_image):
14950 * xselect.c (Fx_register_dnd_atom):
14951 Simplify previous changes by using xpalloc.
14953 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14954 since either will do and ptrdiff_t is convenient with xpalloc.
14956 * charset.c (charset_table_size)
14957 (struct charset_sort_data.priority): Now ptrdiff_t.
14958 (charset_compare): Don't overflow if priorities differ greatly.
14959 (Fsort_charsets): Don't assume list length fits in int.
14960 Check for size-calculation overflow when allocating sort data.
14961 (syms_of_charset): Allocate an initial charset table that is
14962 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14964 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14966 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14967 The actual value is always <= INT_MAX, and leaving it unsigned made
14968 overflow checking harder.
14970 * dispextern.h (struct glyph_matrix.rows_allocated)
14971 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14972 with xpalloc. The values are still always <= INT_MAX.
14974 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14976 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14977 (SAFE_NALLOCA): New macro.
14979 * region-cache.c (struct boundary.pos, find_cache_boundary)
14980 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14981 (set_cache_region, invalidate_region_cache)
14982 (revalidate_region_cache, know_region_cache, region_cache_forward)
14983 (region_cache_backward, pp_cache):
14984 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14985 so that ptrdiff_t * can be passed to xpalloc.
14986 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14987 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14988 (pp_cache): Don't assume cache_len fits in int.
14989 * region-cache.h: Adjust extern decls to match.
14991 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14992 EMACS_INT, since either will do, for xpalloc.
14994 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14995 (xnmalloc, xnrealloc, xpalloc): New functions.
14997 * bidi.c (bidi_shelve_header_size): New constant.
14998 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14999 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15001 * bidi.c (bidi_cache_shrink):
15002 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15004 Don't update size of array until after memory allocation succeeds,
15005 because xmalloc/xrealloc may not return.
15006 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15007 now that we have proper integer overflow checking.
15008 (record_overlay_string, overlay_strings): Catch overflows when
15009 calculating size of overlay_str_buf.
15011 * callproc.c (Fcall_process): Check for size overflow when
15012 calculating size of args2.
15013 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15014 Normally we prefer signed values, but sticking with ptrdiff_t would
15015 require adding more-complicated checks.
15017 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15018 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15019 Redo buffer-overflow calculations to avoid integer overflow.
15020 Add a FIXME comment where memory seems to be over-allocated.
15022 * character.c (Fstring): Check for size-calculation overflow.
15024 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15025 unnecessary integer overflow. Check for size overflow.
15026 (encode_coding_object): Don't update size until xmalloc succeeds.
15028 * composite.c (get_composition_id): Check for overflow in glyph
15029 length calculations.
15031 Integer and memory overflow fixes for display code.
15032 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15033 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15034 (scrolling_window): Check for overflow in size calculations.
15035 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15036 Don't assume glyph table len fits in int.
15037 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
15038 (row_table_size): Now ptrdiff_t, not int.
15039 (scrolling_window): Avoid overflow in size calculations.
15040 Don't update size until allocation succeeds.
15041 * fns.c (concat): Check for overflow in size calculations.
15042 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15043 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15044 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15046 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15047 (get_doc_string): Check for size calculation overflow.
15048 Don't update size until allocation succeeds.
15049 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15050 EMACS_INT, where ptrdiff_t will do.
15051 (Fsubstitute_command_keys): Check for string overflow.
15053 * editfns.c (set_time_zone_rule): Don't assume environment length
15055 (message_length): Now ptrdiff_t, not int.
15056 (Fmessage_box): Don't update size until allocation succeeds.
15057 Don't assume message length fits in int.
15058 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15060 * emacs.c (main): Do not reallocate argv, since there is a null at
15061 the end that can be overwritten, and this way there's no need to
15062 worry about size-calculation overflow.
15063 (sort_args): Check for size-calculation overflow.
15065 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15067 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15069 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15070 (x_set_scroll_bar_width, x_figure_window_size):
15071 Check for integer overflow.
15072 (x_set_alpha): Do not assume XINT fits in int.
15074 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15075 This is for the members text_lines, text_cols, total_lines, total_cols,
15076 where the system imposes an 'int' limit.
15078 * fringe.c (Fdefine_fringe_bitmap):
15079 Don't update size until alloc works.
15081 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15082 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15084 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15085 Check for size-calculation overflow.
15086 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15087 do, as we prefer signed integers.
15088 (id_to_widget.max_size, id_to_widget.used)
15089 (xg_store_widget_in_map, xg_remove_widget_from_map)
15090 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15091 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15092 Use and return ptrdiff_t, not int.
15093 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15094 * gtkutil.h: Change prototypes to match the above.
15096 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15097 are duplicate now that they've been promoted to lisp.h.
15098 (x_allocate_bitmap_record, x_alloc_image_color)
15099 (make_image_cache, cache_image, xpm_load):
15100 Don't update size until alloc is done.
15101 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15103 Check for size calculation overflow.
15104 (ct_colors_allocated_max): New constant.
15105 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15108 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15109 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15110 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15111 Use ptrdiff_t, not int, to count maps.
15112 (read_char_minibuf_menu_prompt): Check for overflow in size
15113 calculations. Don't update size until allocation succeeds.
15114 Redo calculations to avoid overflow.
15115 * keyboard.h: Change prototypes to match the above.
15117 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15119 (current_minor_maps): Check for size calculation overflow.
15120 * keymap.h: Change prototypes to match the above.
15122 * lread.c (read1, init_obarray): Don't update size until alloc done.
15124 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15125 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15127 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15128 Now ptrdiff_t, not int.
15129 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
15130 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
15132 * process.c (Fnetwork_interface_list): Check for overflow
15133 in size calculation.
15135 * region-cache.c (move_cache_gap): Check for size calculation overflow.
15137 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
15138 overflow. Don't bother calling xmalloc when xrealloc will do.

15141 (Fset_match_data): Don't assume list lengths fit in 'int'.
15143 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15144 for command line length. Do not attempt to address one before the
15145 beginning of an array, as that's not portable.
15147 * term.c (max_frame_lines): Remove; unused.
15148 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15150 (encode_terminal_code, calculate_costs): Check for size
15151 calculation overflow.
15152 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
15153 table lengths and related sizes. Don't update size until alloc
15154 done. Redo calculations to avoid overflow.

15157 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15158 subtracting pointers.

15162 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
15163 Don't update size until alloc done.
15164 Redo size calculations to avoid overflow.
15165 Check for size calculation overflow.
15166 (main) [DEBUG]: Fix typo in invoking tparam1.

15173 Use ptrdiff_t, not int, for sizes.
15174 (Finternal_make_lisp_face, cache_face):
15175 Check for size calculation overflow.
15176 (cache_face): Treat size calculation overflows as if they were
15177 memory exhaustion (the usual treatment), rather than aborting.
15179 * xfns.c (x_encode_text, x_set_name_internal)
15180 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15181 sizes, since they can exceed INT_MAX in size. Check for size
15182 calculation overflow.
15184 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15185 (xg_select): Check for size calculation overflow.
15186 Don't update size until alloc done.
15188 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15189 as sprintf is limited to int lengths.
15191 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15192 (X_LONG_MIN): New macros.
15193 Use them to make the following changes clearer.
15194 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15195 This change doesn't affect the value now, but it may help remind
15196 future maintainers not to raise the value too much later.
15197 (SELECTION_QUANTUM): Remove, replacing with ...
15198 (selection_quantum): ... new function, which avoids overflow.
15200 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15201 assumption that selection length fits in 'int'.
15202 (x_reply_selection_request, x_handle_selection_request)
15203 (x_get_window_property, receive_incremental_selection)
15204 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15205 (lisp_data_to_selection_data, clean_local_selection_data):

15207 (x_reply_selection_request, x_get_window_property)
15208 (receive_incremental_selection, x_property_data_to_lisp):
15209 Redo calculations to avoid overflow.
15210 (x_reply_selection_request): When sending hint, ceiling it at
15211 X_LONG_MAX rather than relying on wraparound overflow to send
15213 (x_get_window_property, receive_incremental_selection)
15214 (lisp_data_to_selection_data, x_property_data_to_lisp):
15215 Check for size-calculation overflow.

15218 Don't store size until memory allocation succeeds.
15219 (x_get_window_property): Plug memory leak on memory exhaustion.
15220 Don't double-block input; malloc is safe here. Don't assume 2**34
15221 - 4 fits in unsigned long. Add an xassert to check
15222 XGetWindowProperty overflow. Be more careful about overflow
15223 calculations, and distinguish size from memory overflow better.
15224 (receive_incremental_selection): When tracing, don't assume
15225 unsigned int is less than INT_MAX.
15226 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15227 harmful) conversions of unsigned short to int.
15228 (lisp_data_to_selection_data): Don't assume that integers
15229 in the range -65535 through -1 fit in an X unsigned short.
15230 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15231 result parameters unless successful. Rely on cons_to_unsigned
15232 to report problems with elements; the old code wasn't right anyway.
15233 (x_check_property_data): Check for int overflow; we cannot use
15234 a wider type due to X limits.
15235 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15237 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15239 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15240 (x_term_init): Check for size calculation overflow.
15241 (x_color_cells): Don't store size until memory allocation succeeds.
15242 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15243 Don't assume alloca size is less than MAX_ALLOCA.
15244 (x_term_init): Don't assume length fits in int (sprintf is limited
15247 Use ptrdiff_t for composition IDs.
15248 * character.c (lisp_string_width):
15249 * composite.c (composition_table_size, n_compositions)

15266 * image.c (xpm_get_color_table_h):
15267 * lisp.h (hash_lookup, hash_put):
15268 * minibuf.c (Ftest_completion):
15269 Use ptrdiff_t for hash table indexes, not int (which is too
15270 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15271 32-bit --with-wide-int hosts).
15273 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15274 Add a FIXME comment about memory leaks.
15275 (syms_of_charset): Don't assume xmalloc returns.
15277 Don't assume that stated character widths fit in int.

15279 * character.h (CHAR_WIDTH):
15280 * indent.c (MULTIBYTE_BYTES_WIDTH):
15281 Use sanitize_char_width to avoid undefined and/or bad behavior
15282 with outlandish widths.
15283 * character.h (sanitize_tab_width): Rename from sanitize_width,
15284 now that we have two such functions. All uses changed.
15285 (sanitize_char_width): New inline function.
15287 Don't assume that tab-width fits in int.
15288 * character.h (sanitize_width): New inline function.

15295 * fileio.c: Integer overflow issues with file modes.
15296 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15298 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15299 Remove unreachable code.

15302 * xterm.c: Don't go over XClientMessageEvent limit.
15303 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15304 (x_send_scroll_bar_event): Likewise. Check that the size does not
15305 exceed limits imposed by XClientMessageEvent, as well as the usual
15306 ptrdiff_t and size_t limits.
15308 * keyboard.c: Overflow, signedness and related fixes.
15309 (make_lispy_movement): Use same integer type in forward decl
15310 that is used in the definition.
15311 (read_key_sequence, keyremap_step):
15312 Change bufsize argument back to int, undoing my 2011-03-30 change.
15313 We prefer signed types, and int is wide enough here.
15314 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15315 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15316 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15317 length, not size_t. Use ptrdiff_t for index, not int.
15318 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15319 possibility of integer overflow.
15321 Overflow, signedness and related fixes for images.
15323 * dispextern.h (struct it.stack[0].u.image.image_id)
15324 (struct_it.image_id, struct image.id, struct image_cache.size)

15331 * xdisp.c (calc_pixel_width_or_height):
15332 * xfns.c (image_cache_refcount):
15333 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

15342 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15343 (lookup_image): Remove unnecessary tests.
15344 (xbm_image_p): Locals are now of int, not EMACS_INT,
15345 since parse_image_check makes sure they fit into int.
15346 (png_load, gif_load, svg_load_image):
15347 Prefer int to unsigned where either will do.
15348 (tiff_handler): New function, combining the cores of the
15349 old tiff_error_handler and tiff_warning_handler.
15350 This function is rewritten to use vsnprintf and thereby avoid
15351 stack buffer overflows. It uses only the features of vsnprintf
15352 that are common to both POSIX and native Microsoft.
15353 (tiff_error_handler, tiff_warning_handler): Use it.
15354 (tiff_load, gif_load, imagemagick_load_image):
15355 Don't assume :index value fits in 'int'.
15356 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15357 (imagemagick_load_image): Check that crop parameters fit into
15358 the integer types that MagickCropImage accepts. Don't assume
15359 Vimagemagick_render_type has a nonnegative value. Don't assume
15360 size_t fits in 'long'.
15361 (gs_load): Use printmax_t to print the widest integers possible.
15362 Check for integer overflow when computing image height and width.
15364 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15366 * xdisp.c (redisplay_window): Don't force window start if point
15367 will be invisible in the resulting window. (Bug#9324)

15371 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15372 the display spec is of the form `(space ...)'.
15373 (handle_display_spec): Return the value returned by
15374 handle_single_display_spec, not just 1 or zero.
15375 (handle_single_display_spec): If the display spec is of the form
15376 `(space ...)', and specifies display in the text area, return 2
15378 (try_cursor_movement): Check for the need to scroll more
15379 accurately, and prefer exact match for point under bidi.
15380 Don't advance `row' beyond the last row of the window.
15382 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15383 into disp_prop; all users changed.
15385 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

15397 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15398 buffers, return left-to-right.
15399 (set_cursor_from_row): Consider candidate row a win if its glyph
15400 represents a newline and point is on that newline. Fixes cursor
15401 positioning on the newline at EOL of R2L text within L2R
15402 paragraph, and vice versa.
15403 (try_cursor_movement): Check continued rows, in addition to
15404 continuation rows. Fixes unwarranted scroll when point enters a
15405 continued line of R2L text within an L2R paragraph, or vice versa.
15406 (cursor_row_p): Consider the case of point being equal to
15407 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15408 from the end of a short line to the beginning of a continued line
15409 of R2L text within L2R paragraph.
15410 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15411 composed characters.

15428 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15429 extra slot even if the purpose is char-code-property-table.
15431 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15433 * xdisp.c (redisplay_window): When computing centering_position,
15434 account for the height of the header line. (Bug#8874)
15436 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15437 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15438 candidate is selected by the mouse, and that candidate has a
15439 composed character under the mouse.
15441 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15442 coordinates reported by pos-visible-in-window-p for a composed
15443 character in column zero.
15445 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15447 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15449 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15451 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15452 consider it a hit if to_charpos is anywhere in the range of the
15453 composed buffer positions.
15455 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15457 * image.c (gif_load): Don't assume that each subimage has the same
15458 dimensions as the base image. Handle disposal method that is
15459 "undefined" by the gif spec (Bug#9335).
15461 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15463 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15468 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15469 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15470 from an Org mode buffer to a Speedbar frame.
15472 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15473 a composition, take its buffer position from IT->cmp_it.charpos.
15474 Fixes cursor positioning at the beginning of a line that begins
15475 with a composed character.
15477 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15479 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15480 character bidirectional type, use STRONG_L instead. Fixes crashes
15481 in a buffer produced by `describe-categories'.
15483 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15484 members before the level stack, so they would be saved and
15485 restored when copying iterator state. Fixes incorrect reordering
15486 around TABs covered by display properties.

15514 Fix memory allocation problems in Cygwin build (Bug#9273).
15516 * unexcw.c ( __malloc_initialized): Declare external variable.
15517 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15519 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15521 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

15560 * xdisp.c (move_it_in_display_line_to): Don't invoke
15561 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15562 ppos_it. Fixes vertical cursor motion when line beginning is
15563 covered by an image. (Bug#9296)
15565 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15567 * nsterm.h (ns_run_ascript): Declare.

15573 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15574 the event loop. Get status from as_status (Bug#7276).
15576 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15577 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15578 the event loop (Bug#7276).

15601 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
15603 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15604 (Fnetwork_interface_list): Allocate in increments of bytes instead
15605 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15606 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15608 (struct ifflag_def): notrailers is smart on OSX.
15609 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15610 Get hardware address with getifaddrs if available.
15612 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15614 * xdisp.c (iterate_out_of_display_property): xassert that
15615 IT->position is set to within IT->object's boundaries. Break from
15616 the loop as soon as EOB is reached; avoids infloops in redisplay
15617 when IT->position is set up wrongly due to some bug.
15618 Set IT->current to match the bidi iterator unconditionally.
15619 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15620 entry. Force push_it to save on the stack the current
15621 buffer/string position, to be restored by pop_it. Fix flags in
15622 the iterator structure wrt the object coming from a display
15623 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15624 properties. (Bug#9284)
15626 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15628 * fontset.c (fontset_get_font_group): Add proper type checks.
15631 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15633 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
15634 and LC_VERSION_MIN_MACOSX.
15635 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
15636 (dump_it) [LC_FUNCTION_STARTS]: Use it.
15638 2011-08-08 Eli Zaretskii <eliz@gnu.org>
15640 * xdisp.c (forward_to_next_line_start): Allow to use the
15641 no-display-properties-and-no-overlays under bidi display.
15642 Set disp_pos in the bidi iterator to avoid searches for display
15643 properties and overlays.
15645 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15647 * editfns.c (Fset_time_zone_rule): Document relationship with the
15650 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
15651 the font entity extracted from the cache (Bug#8109).
15653 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15655 * composite.c (autocmp_chars): Don't reset point. That is done by
15656 restore_point_unwind (Bug#5984).
15658 2011-08-07 Juri Linkov <juri@jurta.org>
15660 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15661 to show the arg `TIME' instead of `TIMEVAL'.
15663 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15665 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15666 display property strides EOL and includes a newline, as in
15667 longlines-mode. (Bug#9254)
15668 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15669 word-wrap under bidirectional display. (Bug#9224)
15671 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15672 is non-zero, even if the data buffer is NULL. Fixes a crash in
15673 vertical-motion with longlines-mode. (Bug#9254)
15675 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15677 * bidi.c <bidi_cache_total_alloc>: Now static.
15678 (bidi_initialize): Initialize bidi_cache_total_alloc.
15680 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15683 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15684 amount allocated this far in `bidi_cache_total_alloc'.
15685 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15686 non-zero, only free the data buffer without restoring the cache
15687 contents. All callers changed.
15689 * dispextern.h (bidi_unshelve_cache): Update prototype.
15691 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15692 (move_it_in_display_line, move_it_to)
15693 (move_it_vertically_backward, move_it_by_lines): Replace the call
15694 to xfree to an equivalent call to bidi_unshelve_cache.
15695 (move_it_in_display_line_to): Fix logic of returning
15696 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15698 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15700 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15701 came from a string character with a `cursor' property. (Bug#9229)
15703 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15705 * Makefile.in (LIB_PTHREAD): New variable.
15706 (LIBES): Add LIB_PTHREAD (Bug#9216).
15708 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15709 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15711 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15713 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15715 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15717 * xterm.c (x_find_topmost_parent): New function.
15718 (x_set_frame_alpha): Find topmost parent window with
15719 x_find_topmost_parent and set the property there also (bug#9181).
15720 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15722 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15724 * callproc.c (Fcall_process): Avoid vfork clobbering
15725 the local vars buffer, coding_systems, current_dir.
15727 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15729 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15731 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15733 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15734 so that it is not optimized away.
15736 * xdisp.c (compute_display_string_pos): Remove unused local.
15738 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15740 Fix slow cursor motion and scrolling in large buffers with
15741 selective display, like Org Mode buffers. (Bug#9218)
15743 * dispextern.h (struct bidi_it): New member disp_prop_p.
15745 * xdisp.c: Remove one-slot cache of display string positions.
15746 (compute_display_string_pos): Accept an additional argument
15747 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15748 for a display string or property. If found, set DISP_PROP_P
15751 * bidi.c (bidi_fetch_char): Accept an additional argument
15752 DISP_PROP_P, and pass it to compute_display_string_pos.
15753 Only handle text covered by a display string if DISP_PROP_P is returned
15754 non-zero. All callers of bidi_fetch_char changed.
15756 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15758 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15760 2010-12-03 Don March <don@ohspite.net>
15762 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15763 last character M-[char] is translated to ESC [char] (bug#7541).
15765 2011-08-02 Kenichi Handa <handa@m17n.org>
15767 * lisp.h (uniprop_table): Extern it.
15769 * chartab.c (uniprop_table): Make it non-static.
15771 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15773 * xdisp.c (forward_to_next_line_start): Accept additional argument
15774 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15776 (reseat_at_next_visible_line_start): Use the bidi iterator state
15777 returned by forward_to_next_line_start to restore the state of
15778 it->bidi_it after backing up to previous newline. (Bug#9212)
15780 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15782 * regex.c (re_comp): Protoize.
15783 (re_exec): Fix return type.
15784 (regexec): Fix type of `ret'. (Bug#9203)
15786 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15788 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15789 This is needed if max-image-size is a floating-point number.
15791 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15793 * print.c (print_object): Print empty symbol as ##.
15795 * lread.c (read1): Read ## as empty symbol.
15797 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15799 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15800 setting frame foreground color (Bug#9175).
15801 (x_set_background_color): Likewise.
15803 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15804 contents (Bug#9176).
15805 (EmacsTooltip -init): Remove bezels and add shadows to
15808 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15809 or scroll bar (Bug#8470).
15811 * nsfont.m (nsfont_open): Remove assignment to voffset and
15812 unnecessary vars hshink, expand, hd, full_height, min_height.
15813 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15815 * nsterm.h (nsfont_info): Remove voffset field.
15817 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15819 Implement strike-through and overline on NextStep (Bug#8863).
15821 * nsfont.m (nsfont_open): Use underline position provided by font,
15822 instead of hard-coded value of 2.
15823 (nsfont_draw): Call ns_draw_text_decoration instead.
15825 * nsterm.h: Add declaration for ns_draw_text_decoration.
15827 * nsterm.m (ns_draw_text_decoration): New function for drawing
15828 underline, overline, and strike-through.
15829 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15830 ns_draw_text_decoration. Change treatment of cursor drawing to
15831 accommodate underlining, etc.
15833 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15835 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15838 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15840 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15841 Without this fix, if a signal arrives just after memory fills up,
15842 'malloc' might be invoked reentrantly.
15844 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15845 In other words, assume that every image size is allowed, on non-X
15846 hosts. This assumption is probably wrong, but it lets Emacs compile.
15848 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15850 * regex.c (re_iswctype): Convert return values to boolean.
15852 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15854 * xdisp.c (compute_display_string_pos): Don't use cached display
15855 string position if the buffer had its restriction changed.
15858 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15860 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15862 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15864 Integer signedness and overflow and related fixes. (Bug#9079)
15866 * bidi.c: Integer size and overflow fixes.
15867 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15868 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15869 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15870 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15871 (bidi_find_other_level_edge):
15872 Use ptrdiff_t instead of EMACS_INT where either will do.
15873 This works better on 32-bit hosts configured --with-wide-int.
15874 (bidi_cache_ensure_space): Check for size-calculation overflow.
15875 Use % rather than repeated addition, for better worst-case speed.
15876 Don't set bidi_cache_size until after xrealloc returns, because it
15878 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15879 (bidi_cache_ensure_space): Also check that the bidi cache size
15880 does not exceed that of the largest Lisp string or buffer. See Eli
15881 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15883 * alloc.c (__malloc_size_t): Remove.
15884 All uses replaced by size_t. See Andreas Schwab's note
15885 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15887 * image.c: Improve checking for integer overflow.
15888 (check_image_size): Assume that f is nonnull, since
15889 it is always nonnull in practice. This is one less thing to
15890 worry about when checking for integer overflow later.
15891 (x_check_image_size): New function, which checks for integer
15892 overflow issues inside X.
15893 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15894 This removes the need for a memory_full check.
15895 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15896 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15897 (xbm_read_bitmap_data): Change locals back to 'int', since
15898 their values must fit in 'int'.
15899 (xpm_load_image, png_load, tiff_load):
15900 Invoke x_create_x_image_and_pixmap earlier,
15901 to avoid much needless work if the image is too large.
15902 (tiff_load): Treat overly large images as if
15903 x_create_x_image_and_pixmap failed, not as malloc failures.
15904 (gs_load): Use x_check_image_size.
15906 * gtkutil.c: Omit integer casts.
15907 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15908 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15910 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15912 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15913 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15914 would wrongly return t on a 64-bit host.
15916 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15917 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15918 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15919 and therefore cause GCC to emit a bogus diagnostic in some cases.
15921 * image.c: Integer signedness and overflow and related fixes.
15922 This is not an exhaustive set of fixes, but it's time to
15923 record what I've got.
15924 (lookup_pixel_color, check_image_size): Remove redundant decls.
15925 (check_image_size): Don't assume that arbitrary EMACS_INT values
15926 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15927 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15928 (tiff_load, imagemagick_load_image):
15929 Check for overflow in size calculations.
15930 (x_create_x_image_and_pixmap): Remove unnecessary test for
15931 xmalloc returning NULL; that can't happen.
15932 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15933 (xpm_color_bucket): Use better integer hashing function.
15934 (xpm_cache_color): Don't possibly over-allocate memory.
15935 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15936 (gif_memory_source):
15937 Use ptrdiff_t, not int or size_t, to record sizes.
15938 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15939 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15940 either works, as we prefer signed integers.
15941 (tiff_read_from_memory, tiff_write_from_memory):
15942 Return tsize_t, not size_t, since that's what the TIFF API wants.
15943 (tiff_read_from_memory): Don't fail simply because the read would
15944 go past EOF; instead, return a short read.
15945 (tiff_load): Omit no-longer-needed casts.
15946 (Fimagemagick_types): Don't assume size fits into 'int'.
15948 Improve hashing quality when configured --with-wide-int.
15949 * fns.c (hash_string): New function, taken from sxhash_string.
15950 Do not discard information about ASCII character case; this
15951 discarding is no longer needed.
15952 (sxhash-string): Use it. Change sig to match it. Caller changed.
15953 * lisp.h: Declare it.
15954 * lread.c (hash_string): Remove, since we now use fns.c's version.
15955 The fns.c version returns a wider integer if --with-wide-int is
15956 specified, so this should help the quality of the hashing a bit.
15958 * emacs.c: Integer overflow minor fix.
15959 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15960 Define only if GNU_LINUX.
15961 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15963 * dispnew.c: Integer signedness and overflow fixes.
15964 Remove unnecessary forward decls, that were a maintenance hassle.
15965 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15967 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15968 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15969 (prepare_desired_row, line_draw_cost):
15970 Use int, not unsigned, where either works.
15971 (save_current_matrix, restore_current_matrix):
15972 Use ptrdiff_t, not size_t, where either works.
15973 (init_display): Check for overflow more accurately, and without
15974 relying on undefined behavior.
15976 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15977 Remove, replacing with the new symbols in lisp.h. All uses changed.
15978 * fileio.c (make_temp_name):
15979 * filelock.c (lock_file_1, lock_file):
15980 * xdisp.c (message_dolog):
15981 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15982 Use pMd etc. instead.
15983 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15984 replacing the pWIDE etc. symbols removed from editfns.c.
15986 * keyboard.h (num_input_events): Now uintmax_t.
15987 This is (very slightly) less likely to mess up due to wraparound.
15990 * buffer.c: Integer signedness fixes.
15991 (alloc_buffer_text, enlarge_buffer_text):
15992 Use ptrdiff_t rather than size_t when either will do, as we prefer
15995 * alloc.c: Integer signedness and overflow fixes.
15996 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15997 (__malloc_size_t): Default to size_t, not to int.
15998 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15999 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16000 Prefer ptrdiff_t to size_t when either would do, as we prefer
16002 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16003 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16004 Now const. Initialize with values that are in range even if char
16006 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16007 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16008 These functions do the right thing with sizes > 2**32.
16009 (check_depth): Now ptrdiff_t, not int.
16010 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16011 Adjust to new way of storing sizes. Check for size overflow bugs
16013 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16014 slightly wrong anyway, as it missed one instance of
16015 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16016 (refill_memory_reserve): Omit needless cast to size_t.
16017 (mark_object_loop_halt): Mark as externally visible.
16019 * xselect.c: Integer signedness and overflow fixes.
16020 (Fx_register_dnd_atom, x_handle_dnd_message):
16021 Use ptrdiff_t, not size_t, since we prefer signed.
16022 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16023 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16024 x_dnd_atoms_size and x_dnd_atoms_length.
16026 * doprnt.c: Prefer signed to unsigned when either works.
16028 * doprnt.c (doprnt):
16030 * xdisp.c (vmessage):
16031 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16032 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16033 prefer signed arithmetic to avoid comparison confusion.
16034 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16035 but is a bit tricky.
16037 Assume freestanding C89 headers, string.h, stdlib.h.
16038 * data.c, doprnt.c, floatfns.c, print.c:
16039 Include float.h unconditionally.
16040 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16041 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16042 * regex.c: Likewise for stddef.h, string.h.
16043 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16044 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16045 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16046 (STDC_HEADERS): Remove obsolete defines.
16047 * sysdep.c: Include limits.h unconditionally.
16049 Assume support for memcmp, memcpy, memmove, memset.
16050 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16051 * regex.c (memcmp, memcpy):
16052 Remove; we assume C89 now.
16054 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16055 (__malloc_safe_bcopy): Remove; no longer needed.
16057 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16058 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16059 well either way, and we prefer signed to unsigned.
16061 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16063 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16064 closes the connection while we're reading (bug#9182).
16066 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16068 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16069 are specified (Bug#9168).
16071 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16073 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16074 Found by GCC static checking and --with-wide-int on a 32-bit host.
16076 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16078 * xdisp.c (compute_display_string_pos): Fix logic of caching
16079 previous display string position. Initialize cached_prev_pos to
16080 -1. Fixes slow-down at the beginning of a buffer.
16082 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16084 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16085 for attrs[LFACE_FONTSET_INDEX].
16087 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16089 * xml.c (parse_region): Remove unused local
16090 that was recently introduced.
16092 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16094 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16095 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16097 * xdisp.c (move_it_in_display_line_to): Record the best matching
16098 position for TO_CHARPOS while scanning the line, and restore it on
16099 exit if none of the characters scanned was an exact match.
16100 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16101 when exact match is impossible due to invisible text, and the
16102 lines are truncated.
16104 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16106 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16109 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16111 Fix a significant slow-down of cursor motion with C-n, C-p,
16112 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16113 auto-repeat under bidi redisplay in fontified buffers.
16114 * xdisp.c (compute_stop_pos_backwards): New function.
16115 (next_element_from_buffer): Call compute_stop_pos_backwards to
16116 find a suitable prev_stop when we find ourselves before
16118 (reseat): Don't look for prev_stop, as that could mean a very long
16120 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16121 <cached_disp_overlay_modiff>: Cache for last found display string
16123 (compute_display_string_pos): Return the cached position if asked
16124 about the same buffer in the same area of character positions, and
16125 the buffer wasn't changed since the time the display string
16126 position was cached.
16128 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16130 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16131 is an integer, which is important for empty lines. (Bug#9149)
16133 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16135 * frame.c (Fmodify_frame_parameters): In tty case, update the
16136 default face if necessary (Bug#4238).
16138 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16140 * editfns.c (Fstring_to_char): No need to explain what a character
16141 is in the docstring (Bug#6576).
16143 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16145 * xml.c (parse_region): Make sure we always return a tree.
16147 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16149 * xml.c (parse_region): If a document contains only comments,
16152 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16154 * xml.c (make_dom): Return comments, too.
16156 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16159 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16160 and the surrounding thread.
16161 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16162 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16163 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16165 * s/openbsd.h (BROKEN_SIGIO): Define.
16166 * unexelf.c (unexec) [__OpenBSD__]:
16167 Don't update the .mdebug section of the Alpha COFF symbol table.
16169 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16171 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16174 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16176 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16177 This fixes some race conditions on the permissions of any newly
16180 * alloc.c (valid_pointer_p): Use pipe, not open.
16181 This fixes some permissions issues when debugging.
16183 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16184 If fchown fails to set both uid and gid, try to set just gid,
16185 as that is sometimes allowed. Adjust the file's mode to eliminate
16186 setuid or setgid bits that are inappropriate if fchown fails.
16188 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16190 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16191 to compare Lisp_Objects.

16196 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16198 * lread.c (read_integer): Unread even EOF character.
16199 (read1): Likewise. Properly record start position of symbol.
16201 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16202 symbol character follows.
16204 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16206 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16207 This works around a problem with the previous change to Fcopy_file.
16208 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16209 and without this change, GCC might complain about discarding
16210 fchown's return value.
16212 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16214 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16216 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16218 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16220 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16222 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16223 it's used from the C level.
16225 * process.c: Use the same condition for POLL_FOR_INPUT in both
16226 keyboard.c and process.c (bug#1858).
16228 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16230 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16231 (Fgnutls_boot): Use it.
16233 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16235 * doc.c (Fsubstitute_command_keys): Revert last change.
16237 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16239 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16240 quotes the next character, and doesn't affect other longer
16241 sequences (bug#8935).
16243 * lread.c (syms_of_lread): Clarify that is isn't only
16244 `eval-buffer' and `eval-defun' that's affected by
16245 `lexical-binding' (bug#8460).
16247 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16249 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16250 bidi redisplay when a line includes both an image and is truncated.
16252 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16254 Fix minor problems found by static checking.
16255 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16256 (elsz): Now a signed constant, not a size_t var. We prefer signed
16257 types to unsigned, to avoid integer comparison confusion. Without
16258 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16259 "cannot optimize loop, the loop counter may overflow", a symptom
16261 * indent.c (Fvertical_motion): Mark locals as initialized.
16262 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16264 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16266 * search.c (Fre_search_backward): Mention `case-fold-search' in
16267 all the re_search_* functions (bug#8138).

16287 buffer position was specified. Initialize paragraph_embedding to
16289 (reseat_to_string): Initialize the bidi iterator.
16290 (display_string): If we need to ignore text properties of
16291 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16292 original value of -1 will not work with bidi.)
16293 (compute_display_string_pos): First arg is now struct
16294 `text_pos *'; all callers changed. Support display properties on
16296 (compute_display_string_end): Support display properties on Lisp
16298 (init_iterator, reseat_1, reseat_to_string): Initialize the
16299 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16300 when iterating on a string not from display properties).
16301 (compute_display_string_pos, compute_display_string_end):
16302 Fix calculation of the object to scan. Fixes an error when using
16304 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16305 base_level_stop; instead, set base_level_stop to BEGV.
16306 Fixes crashes in vertical-motion.
16307 (next_element_from_buffer): Improve commentary for when
16308 the iterator is before prev_stop.
16309 (init_iterator): Initialize bidi_p from the default value of
16310 bidi-display-reordering, not from buffer-local value. Use the
16311 buffer-local value only if initializing for buffer iteration.
16312 (handle_invisible_prop): Support invisible properties on strings
16313 that are being bidi-reordered.
16314 (set_iterator_to_next): Support bidi reordering of C strings and
16316 (next_element_from_string): Support bidi reordering of Lisp

16320 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16321 (init_iterator): Don't initialize it->bidi_p for strings
16323 (reseat_to_string): Initialize it->bidi_p for strings here.

16330 character that is not the first one in the visual order.
16331 (get_visually_first_element): New function, refactored from common
16332 parts of next_element_from_buffer, next_element_from_string, and
16333 next_element_from_c_string.
16334 (tool_bar_lines_needed, redisplay_tool_bar)
16335 (display_menu_bar): Force left-to-right direction. Add a FIXME
16336 comment for making that be controlled by a user option.
16337 (push_it, pop_it): Save and restore the state of the
16338 bidi iterator. Save and restore the bidi_p flag.
16339 (pop_it): Iterate out of display property for string iteration as
16341 (iterate_out_of_display_property): Support iteration over strings.
16342 (handle_single_display_spec): Set up it->bidi_it for iteration
16343 over a display string, and call bidi_init_it.
16344 (handle_single_display_spec, next_overlay_string)
16345 (get_overlay_strings_1, push_display_prop): Set up the bidi
16346 iterator for displaying display or overlay strings.
16347 (forward_to_next_line_start): Don't use the shortcut if
16349 (back_to_previous_visible_line_start): If handle_display_prop
16350 pushed the iterator stack, restore the internal state of the bidi
16351 iterator by calling bidi_pop_it same number of times.
16352 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16353 and we are bidi-iterating, don't decrement the iterator position;
16354 instead, set the first_elt flag in the bidi iterator, to produce
16356 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16357 (push_display_prop): xassert that we are iterating a buffer.
16358 (push_it, pop_it): Save and restore paragraph_embedding member.
16359 (handle_single_display_spec, next_overlay_string)
16360 (get_overlay_strings_1, reseat_1, reseat_to_string)
16361 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16362 correctly. Don't assume unibyte strings are not bidi-reordered.
16363 (compute_display_string_pos)
16364 (compute_display_string_end): Fix handling the case of C string.
16365 (push_it, pop_it): Save and restore from_disp_prop_p.

16370 popping after iteration over a string that came from a display
16371 property. Fix a typo in popping stretch info. Add an assertion
16372 for verifying that the iterator position is in sync with the bidi
16374 (handle_single_display_spec, get_overlay_strings_1)

16388 (try_scrolling, redisplay_window, display_line): Use them when
16389 saving a temporary copy of the iterator and restoring it back.
16390 (back_to_previous_visible_line_start, reseat_1)
16391 (init_iterator): Empty the bidi cache "stack".
16392 (move_it_in_display_line_to): If iterator ended up at
16393 EOL, but we never saw any buffer positions smaller than
16394 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16395 motion in bidi-reordered lines.

16397 immediately before the call to set_iterator_to_next. Fixes cursor
16398 motion in bidi-reordered lines with stretch glyphs and strings
16399 displayed in margins. (Bug#8133) (Bug#8867)
16400 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16402 (pos_visible_p): Support positions in bidi-reordered lines.
16403 Save and restore bidi cache.
16405 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16406 (bidi_paragraph_info): Delete unused struct.
16407 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
16408 (bidi_cache_start): New variable.

16424 Support iteration over a string.
16425 (bidi_set_sor_type, bidi_resolve_explicit_1)
16426 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16427 can now be zero (for strings); special values 0 and -1 were
16428 changed to -1 and -2, respectively.
16429 (bidi_char_at_pos): New function.
16430 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16516 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16518 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16519 The old code sometimes used this field without initializing it.
16521 * alloc.c (gc_sweep): Don't read past end of array.
16522 In theory, the old code could also have corrupted Emacs internals,
16523 though it'd be very unlikely.

16790 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

16827 Random fixes. E.g., (random) never returned negative values.
16828 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16829 subseconds part to the entropy, as that's a bit more random.
16830 Prefer signed to unsigned, since the signedness doesn't matter and
16831 in general we prefer signed. When given a limit, use a
16832 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16833 latter isn't right if USE_2_TAGS_FOR_INTS.
16834 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16835 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16847 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16848 This is more efficient than Ffile_directory_p and avoids a minor race.
16850 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16852 * buffer.c (Foverlay_put): Say what the return value is
16855 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16856 is a directory before asking whether to use the file name

16859 error be more correct.
16861 * fns.c (Frequire): Remove the mention of the .gz files, since
16862 that's installation-specific, but keep the mention of

16875 Qgnutls_bootprop_verify_error (which is no longer used).
16877 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16878 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16879 Also (re)move comments that are misplaced or no longer relevant.

16908 * lread.c (syms_of_lread): Mention single symbols defined by

16980 * eval.c (struct backtrace): Simplify and port the data structure.
16981 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16982 signed bit field, as this assumption is not portable and it makes
16983 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16984 "char debug_on_exit : 1" as this is not portable either; instead,
16985 use the portable "unsigned int debug_on_exit : 1". Remove unused
16986 member evalargs. Remove obsolete comments about cc bombing out.
16988 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
16990 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

17058 (emacs_fixed_get_preferred_height): Use min_width/height from
17059 frames size_hint to set minimum and natural (Bug#8919).
17060 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17061 and use min_width/height from frames size_hint to set
17062 min_width/height (Bug#8919).

17155 (PRINTPREPARE, printchar, strout):
17156 Don't set size unless allocation succeeds.
17158 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17159 for sizes. Check for string overflow more accurately.

17163 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17164 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17170 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17172 * lread.c: Integer overflow fixes.
17173 (read_integer): Radix is now EMACS_INT, not int,
17174 to improve quality of diagnostics for out-of-range radices.
17175 Calculate buffer size correctly for out-of-range radices.
17176 (read1): Check for integer overflow in radices, and in
17177 read-circle numbers.
17178 (read_escape): Avoid int overflow.
17179 (Fload, openp, read_buffer_size, read1)
17180 (substitute_object_recurse, read_vector, read_list, map_obarray):
17181 Use ptrdiff_t, not int, for sizes.

17196 2011-06-22 Leo Liu <sdl.web@gmail.com>
17198 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17199 Move to minibuffer.el.
17201 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17203 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17204 The following patches are for when GLYPH_DEBUG && !XASSERT.
17205 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17206 * dispnew.c (flush_stdout):
17207 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17208 Mark as externally visible.
17209 * dispnew.c (check_window_matrix_pointers): Now static.
17210 * dispnew.c (window_to_frame_vpos):
17211 * xfns.c (unwind_create_frame):

17218 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17220 (debug_method_add): Use va_list and vsprintf rather than relying
17221 on undefined behavior with wrong number of arguments.
17222 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17223 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17224 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17225 since we're not interested in debugging glyphs with old libraries.
17226 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17227 GCC 4.6.0's static checking.
17229 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

17247 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17248 (.bitmaps_last, struct x_output.icon_bitmap):
17249 Use ptrdiff_t, not int, for bitmap indexes.
17250 (x_allocate_bitmap_record): Check for size overflow.

17263 Use ptrdiff_t, not int, for sizes.
17264 (overlays_at, overlays_in): Check for size-calculation overflow.
17266 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17268 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17269 (x_session_initialize): Do not assume string length fits in int.
17271 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17272 This is unlikely, but can occur if DPI is outlandish.
17274 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17275 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17277 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17278 * xrdb.c (magic_file_p, search_magic_path):
17279 Omit last arg SUFFIX; it was always 0. All callers changed.
17280 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17282 * xfont.c (xfont_match): Avoid need for strlen.

17287 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17288 not unsigned long, as we prefer signed integers. All callers changed.
17289 Detect integer overflow in repeat count.
17290 (message_dolog): Don't assume print length fits in 39 bytes.
17291 (display_mode_element): Don't assume strlen fits in int.
17293 * termcap.c: Don't assume sizes fit in int and never overflow.
17294 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17295 (gobble_line): Check for size-calculation overflow.
17297 * minibuf.c (Fread_buffer):
17298 * lread.c (intern, intern_c_string):
17299 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

17314 Reformulate so as not to need the command string.
17315 Invoke gzip -cd rather than gunzip, as it's more portable.
17316 (lock_info_type, lock_file_1, lock_file):
17317 Don't assume pid_t and time_t fit in unsigned long.
17318 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17319 (current_lock_owner): Prefer signed type for sizes.
17320 Use memcpy, not strncpy, where memcpy is what is really wanted.
17321 Don't assume (via atoi) that time_t and pid_t fit in int.
17322 Check for time_t and/or pid_t out of range, e.g., via a network share.
17323 Don't alloca where an auto var works fine.
17325 * fileio.c: Fix some integer overflow issues.
17326 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):

17328 (directory_file_name): Don't assume string length fits in long.
17329 (make_temp_name): Don't assume pid fits in int, or that its print
17330 length is less than 20.

17349 (Fgetenv_internal):
17350 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17352 * lread.c (invalid_syntax): Omit length argument.
17353 All uses changed. This doesn't fix a bug, but it simplifies the
17354 code away from its former Hollerith-constant appearance, and it's
17355 one less 'int' to worry about when looking at integer-overflow issues.
17356 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17358 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17359 This didn't break anything, but it didn't help either.
17360 It's confusing to put a bogus integer in a place where the actual
17361 value does not matter.
17362 (LIST_END_P): Remove unused macro and its bogus comment.
17363 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17365 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17366 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17368 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17369 We prefer signed types, and the value cannot exceed the EMACS_INT
17370 range anyway (because otherwise the length would not be representable).
17371 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17372 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17373 This avoids a GCC warning when WIDE_EMACS_INT.
17375 * indent.c (sane_tab_width): New function.
17376 (current_column, scan_for_column, Findent_to, position_indentation)
17377 (compute_motion): Use it. This is just for clarity.
17378 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17380 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17382 * lisp.h (lint_assume): New macro.
17383 * composite.c (composition_gstring_put_cache):
17384 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17386 * editfns.c, insdel.c:
17387 Omit unnecessary forward decls, to simplify future changes.
17389 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17391 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17393 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17394 Use much-faster test for byte-length change.
17395 Don't assume string byte-length fits in 'int'.
17396 Check that character arg fits in 'int'.
17397 (mapcar1): Declare byte as byte, for clarity.
17399 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17401 * fns.c (concat): Catch string overflow earlier.
17402 Do not rely on integer wraparound.
17404 * dispextern.h (struct it.overlay_strings_charpos)
17405 (struct it.selective): Now EMACS_INT, not int.
17406 * xdisp.c (forward_to_next_line_start)
17407 (back_to_previous_visible_line_start)
17408 (reseat_at_next_visible_line_start, next_element_from_buffer):
17409 Don't arbitrarily truncate the value of 'selective' to int.
17411 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17413 * composite.c: Don't truncate sizes to 'int'.
17414 (composition_gstring_p, composition_reseat_it)
17415 (composition_adjust_point): Use EMACS_INT, not int.
17416 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17417 not EMACS_UINT, for indexes.
17419 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17421 * buffer.c: Include <verify.h>.
17422 (struct sortvec.priority, struct sortstr.priority):
17423 Now EMACS_INT, not int.
17424 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17425 (struct sortstr.size, record_overlay_string)
17426 (struct sortstrlist.size, struct sortlist.used):
17427 Don't truncate size to int.
17428 (record_overlay_string): Check for size-calculation overflow.
17429 (init_buffer_once): Check at compile-time, not run-time.
17431 2011-06-22 Jim Meyering <meyering@redhat.com>
17433 Don't leak an XBM-image-sized buffer
17434 * image.c (xbm_load): Free the image buffer after using it.
17436 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17439 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17440 that Sun C diagnosed.
17441 * fns.c (secure_hash): Fix pointer signedness issue.
17442 * intervals.c (static_offset_intervals): New function.
17443 (offset_intervals): Use it.
17445 2011-06-21 Leo Liu <sdl.web@gmail.com>
17448 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17451 * fns.c (secure_hash): Rename from crypto_hash_function and change
17452 the first arg to accept symbols.
17453 (Fsecure_hash): New primitive.
17454 (syms_of_fns): New symbols.
17456 2011-06-20 Deniz Dogan <deniz@dogan.se>
17458 * process.c (Fset_process_buffer): Clarify return value in
17461 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17463 * dispnew.c (add_window_display_history): Use BVAR.
17465 * xdisp.c (debug_method_add): Use BVAR.
17466 (check_window_end, dump_glyph_matrix, dump_glyph)
17467 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17469 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17472 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17473 check till after the cache is created in init_frame_faces.
17475 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17477 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17479 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17481 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17482 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17483 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17485 Improve buffer-overflow checking (Bug#8873).
17486 * fileio.c (Finsert_file_contents):
17487 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17488 Remove the old (too-loose) buffer overflow checks.
17489 They weren't needed, since make_gap checks for buffer overflow.
17490 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17491 The old code merely checked for Emacs fixnum overflow, and relied
17492 on undefined (wraparound) behavior. The new code avoids undefined
17493 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17495 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17496 Tune. Don't use wider integers than needed. Don't use alloca.
17497 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17499 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17501 * insdel.c, lisp.h (buffer_overflow): New function.
17502 (insert_from_buffer_1, replace_range, replace_range_2):
17503 * insdel.c (make_gap_larger):
17504 * editfns.c (Finsert_char):
17505 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17507 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17509 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17511 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17513 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17514 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17516 * fileio.c: Don't assume EMACS_INT fits in off_t.
17517 (emacs_lseek): New static function.
17518 (Finsert_file_contents, Fwrite_region): Use it.
17519 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17521 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17523 * fns.c: Don't overflow int when computing a list length.
17524 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17525 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17526 truncation on 64-bit hosts. Check for QUIT every
17527 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17528 faster and is responsive enough.
17529 (Flength): Report an error instead of overflowing an integer.
17530 (Fsafe_length): Return a float if the value is not representable
17531 as a fixnum. This shouldn't happen except in contrived situations.
17532 (Fnthcdr, Fsort): Don't assume list length fits in int.
17533 (Fcopy_sequence): Don't assume vector length fits in int.
17535 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17536 (header_size, word_size): New constants.
17537 (allocate_vectorlike): Don't check size overflow here.
17538 (allocate_vector): Check it here instead, since this is the only
17539 caller of allocate_vectorlike that could cause overflow.
17540 Check that the new vector's length is representable as a fixnum.
17542 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17543 The previous code was bogus. For example, next_almost_prime (32)
17544 returned 39, which is undesirable as it is a multiple of 3; and
17545 next_almost_prime (24) returned 25, which is a multiple of 5 so
17546 why was the code bothering to check for multiples of 7?
17548 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17550 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17552 Variadic C functions now count arguments with ptrdiff_t.
17553 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17554 Back then I didn't know that the Emacs coding style prefers signed int.
17555 Also, in the meantime I found a few more instances where arguments
17556 were being counted with int, which may truncate counts on 64-bit
17557 machines, or EMACS_INT, which may be unnecessarily wide.
17558 * lisp.h (struct Lisp_Subr.function.aMANY)
17559 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17560 Arg counts are now ptrdiff_t, not size_t.
17561 All variadic functions and their callers changed accordingly.
17562 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17563 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17564 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17565 * callint.c (Fcall_interactively): Check arg count for overflow,
17566 to avoid potential buffer overrun. Use signed char, not 'int',
17567 for 'varies' array, so that we needn't bother to check its size
17568 calculation for overflow.
17569 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17570 * eval.c (apply_lambda):
17571 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17572 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17573 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17575 * callint.c (Fcall_interactively): Don't use index var as event count.
17577 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17578 * mem-limits.h (SIZE): Remove; no longer used.
17580 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17582 Remove unnecessary casts.
17583 * xterm.c (x_term_init):
17584 * xfns.c (x_set_border_pixel):
17585 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17586 These aren't needed now that we assume ANSI C.
17588 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17589 It's more likely to cause problems (due to unsigned overflow)
17592 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17594 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17596 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17598 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17600 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17602 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17604 GLYPH_CODE_FACE returns EMACS_INT, not int.
17605 * dispextern.h (merge_faces):
17606 * xfaces.c (merge_faces):
17607 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17608 Don't assume EMACS_INT fits in int.
17610 * character.h (CHAR_VALID_P): Remove unused parameter.
17611 * fontset.c, lisp.h, xdisp.c: All uses changed.
17613 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17615 * fns.c (concat): Minor tuning based on overflow analysis.
17616 This doesn't fix any bugs. Use int to hold character, instead
17617 of constantly refetching from Emacs object. Use XFASTINT, not
17618 XINT, for value known to be a character. Don't bother comparing
17619 a single byte to 0400, as it's always less.
17621 * floatfns.c (Fexpt):
17622 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17624 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17627 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17629 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17630 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17631 incorrectly succeed when S was a string, because 4294967386 was
17632 truncated before it was used.
17634 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17635 Otherwise, an out-of-range integer could cause undefined behavior
17638 * composite.c: Use int, not EMACS_INT, for characters.
17639 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17640 EMACS_INT, for values that are known to be in character range.
17641 This doesn't fix any bugs but is the usual style inside Emacs and
17642 may generate better code on 32-bit machines.
17644 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17645 This is for reasons similar to the recent CHAR_STRING fix.
17646 * charset.c (Fencode_char): Check that character arg is actually
17647 a character. Pass an int to ENCODE_CHAR.
17648 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17649 wider than 'int', as a compile-time check to prevent future regressions
17652 * character.c (char_string): Remove unnecessary casts.
17654 Make sure a 64-bit char is never passed to CHAR_STRING.
17655 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17656 by silently ignoring the top 32 bits, allowing some values
17657 that were far too large to be valid characters.
17658 * character.h: Include <verify.h>.
17659 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17660 arguments are no wider than unsigned, as a compile-time check
17661 to prevent future regressions in this area.
17663 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17664 (Fsubst_char_in_region):
17666 * xdisp.c (decode_mode_spec_coding):
17667 Adjust to CHAR_STRING's new requirement.
17668 * editfns.c (Finsert_char, Fsubst_char_in_region):
17669 * fns.c (concat): Check that character args are actually
17670 characters. Without this test, these functions did the wrong
17671 thing with wildly out-of-range values on 64-bit hosts.
17673 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17674 These casts should not be needed on 32-bit hosts, either.
17675 * keyboard.c (read_char):
17676 * lread.c (Fload): Remove casts to unsigned.
17678 * lisp.h (UNSIGNED_CMP): New macro.
17679 This fixes comparison bugs on 64-bit hosts.
17680 (ASCII_CHAR_P): Use it.
17681 * casefiddle.c (casify_object):
17682 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17683 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17684 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17685 * dispextern.h (FACE_FROM_ID):
17686 * keyboard.c (read_char): Use UNSIGNED_CMP.
17688 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17689 not to EMACS_INT, to avoid GCC warning.
17691 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17693 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17694 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17695 isn't needed on 32-bit machines.
17697 * buffer.c (Fgenerate_new_buffer_name):
17698 Use EMACS_INT for count, not int.
17699 (advance_to_char_boundary): Return EMACS_INT, not int.
17701 * data.c (Qcompiled_function): Now static.
17703 * window.c (window_body_lines): Now static.
17705 * image.c (gif_load): Rename local to avoid shadowing.
17707 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17708 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17709 * alloc.c (make_save_value): Integer argument is now of type
17710 ptrdiff_t, not int.
17711 (mark_object): Use ptrdiff_t, not int.
17712 * lisp.h (pD): New macro.
17713 * print.c (print_object): Use it.
17715 * alloc.c: Use EMACS_INT, not int, to count objects.
17716 (total_conses, total_markers, total_symbols, total_vector_size)
17717 (total_free_conses, total_free_markers, total_free_symbols)
17718 (total_free_floats, total_floats, total_free_intervals)
17719 (total_intervals, total_strings, total_free_strings):
17720 Now EMACS_INT, not int. All uses changed.
17721 (Fgarbage_collect): Compute overall total using a double, so that
17722 integer overflow is less likely to be a problem. Check for overflow
17723 when converting back to an integer.
17724 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17725 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17726 These were 'int' variables that could overflow on 64-bit hosts;
17727 they were never used, so remove them instead of repairing them.
17728 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17729 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17730 Previously, this ceilinged at INT_MAX, but that doesn't work on
17732 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17734 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17735 (allocate_vectorlike): Check for ptrdiff_t overflow.
17736 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17737 when a (possibly-narrower) signed value would do just as well.
17738 We prefer using signed arithmetic, to avoid comparison confusion.
17740 * alloc.c: Catch some string size overflows that we were missing.
17741 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17742 for convenience in STRING_BYTES_MAX.
17743 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17744 The definition here is exact; the one in lisp.h was approximate.
17745 (allocate_string_data): Check for string overflow. This catches
17746 some instances we weren't catching before. Also, it catches
17747 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17748 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17749 and ptrdiff_t and EMACS_INT are both 64 bits.
17751 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17752 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17753 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17755 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17757 * alloc.c (Fmake_string): Check for out-of-range init.
17759 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17761 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17763 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17765 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17766 xg_get_default_scrollbar_width.
17768 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17769 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17770 (style_changed_cb): Call update_theme_scrollbar_width and call
17771 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17772 all frames (Bug#8505).
17773 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17774 Call gtk_window_set_resizable if HAVE_GTK3.
17775 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17776 and height if HAVE_GTK3 (Bug#8505).
17777 (scroll_bar_width_for_theme): New variable.
17778 (update_theme_scrollbar_width): New function.
17779 (xg_get_default_scrollbar_width): Move code to
17780 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17781 (xg_initialize): Call update_theme_scrollbar_width.
17783 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17785 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17787 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17789 * frame.c (make_frame): Call other_buffer_safely instead of
17792 * window.c (temp_output_buffer_show): Call display_buffer with
17793 second argument Vtemp_buffer_show_specifiers and reset latter
17794 immediately after the call.
17795 (Vtemp_buffer_show_specifiers): New variable.
17796 (auto_window_vscroll_p, next_screen_context_lines)
17797 (Vscroll_preserve_screen_position): Remove leading asterisks from
17800 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>

18245 (Fframe_root_window, Fframe_first_window)
18246 (Fframe_selected_window): Move here from frame.c. Accept frame
18247 or arbitrary window as argument. Update doc-strings.
18248 (Fminibuffer_window): Move up in code.
18249 (Fwindow_minibuffer_p): Move up in code and simplify.
18250 (Fset_frame_selected_window): Move here from frame.c.
18252 (Fselected_window, select_window, Fselect_window): Move up in
18253 code. Minor doc-string fixes.
18255 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18257 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18258 Do not assume that spare memory exists; that assumption is valid
18259 only if SYSTEM_MALLOC.
18260 (LARGE_REQUEST): New macro, so that the issue of large requests
18261 is separated from the issue of spare memory.
18263 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
18265 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

18280 min width by calling x_set_scroll_bar_default_width (Bug#8505).
18282 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
18284 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
18286 2011-06-04 Chong Yidong <cyd@stupidchicken.com>
18288 * xselect.c (x_clipboard_manager_save): Remove redundant arg.
18289 (x_clipboard_manager_save): Add return value.
18290 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
18291 New error handlers.
18292 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18293 Obey Vx_select_enable_clipboard_manager. Catch errors in
18294 x_clipboard_manager_save (Bug#8779).
18295 (Vx_select_enable_clipboard_manager): New variable.
18296 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18298 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18300 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18302 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18304 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18305 in the current matrix if keep_current_p is non-zero.

18309 * bidi.c (bidi_level_of_next_char): Fix last change.
18311 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18313 Support bidi reordering of text covered by display properties.
18315 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18316 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18317 (bidi_cache_search, bidi_cache_iterator_state)
18318 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18319 (bidi_level_of_next_char, bidi_move_to_visually_next):
18320 Support character positions inside a run of characters covered by a
18322 (bidi_paragraph_init, bidi_resolve_explicit_1)
18323 (bidi_level_of_next_char): Call bidi_fetch_char and
18324 bidi_fetch_char_advance instead of FETCH_CHAR and
18325 FETCH_CHAR_ADVANCE.
18326 (bidi_init_it): Initialize new members.
18327 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18329 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18330 instead of using explicit *_CHAR codes.
18331 (bidi_resolve_explicit, bidi_resolve_weak):
18332 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18333 bidirectional text is supported only in multibyte buffers.
18334 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18335 it to initialize the frame_window_p member of struct bidi_it.
18336 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18337 (bidi_resolve_explicit, bidi_resolve_weak)

18339 bidi_it->nchars is non-positive.
18340 (bidi_level_of_next_char): Don't try to lookup the cache for the
18341 next/previous character if nothing is cached there yet, or if we
18342 were just reseat()'ed to a new position.
18344 * xdisp.c (set_cursor_from_row): Set start and stop points
18345 according to the row's direction when priming the loop that looks
18346 for the glyph on which to display cursor.
18347 (single_display_spec_intangible_p): Function deleted.
18348 (display_prop_intangible_p): Reimplement to call
18349 handle_display_spec instead of single_display_spec_intangible_p.
18350 Accept 3 additional arguments needed by handle_display_spec.
18351 This fixes incorrect cursor motion across display property with complex
18352 values: lists, `(when COND...)' forms, etc.
18353 (single_display_spec_string_p): Support property values that are
18354 lists with the argument STRING its top-level element.
18355 (display_prop_string_p): Fix the condition for processing a
18356 property that is a list to be consistent with handle_display_spec.
18357 (handle_display_spec): New function, refactored from the
18358 last portion of handle_display_prop.
18359 (compute_display_string_pos): Accept additional argument
18360 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18361 value of a `display' property is a "replacing spec".
18362 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18363 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18364 the display property, but just return a value indicating whether
18365 the display property will replace the characters it covers.
18366 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18367 frame_window_p members of struct bidi_it.
18368 (compute_display_string_pos, compute_display_string_end):
18370 (push_it): Accept second argument POSITION, where pop_it should
18371 jump to continue iteration.
18372 (reseat_1): Initialize bidi_it.disp_pos.
18374 * keyboard.c (adjust_point_for_property): Adjust the call to
18375 display_prop_intangible_p to its new signature.
18377 * dispextern.h (struct bidi_it): New member frame_window_p.
18378 (bidi_init_it): Update prototypes.
18379 (display_prop_intangible_p): Update prototype.
18380 (compute_display_string_pos, compute_display_string_end):
18381 Declare prototypes.
18382 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18385 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18387 Malloc failure behavior now depends on size of allocation.
18388 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18389 * lisp.h: Change signatures accordingly.
18390 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18391 All callers changed. (Bug#8762)
18393 * gnutls.c: Use Emacs's memory allocators.
18394 Without this change, the gnutls library would invoke malloc etc.
18395 directly, which causes problems on non-SYNC_INPUT hosts, and which
18396 runs afoul of improving memory_full behavior. (Bug#8761)
18397 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18398 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18399 xfree instead of the default malloc, realloc, free.
18400 (Fgnutls_boot): No need to check for memory allocation failure,
18401 since xmalloc does that for us.
18403 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18404 * category.c (hash_get_category_set):
18405 * ccl.c (ccl_driver):
18406 * charset.c (Fdefine_charset_internal):
18407 * charset.h (struct charset.hash_index):
18408 * composite.c (get_composition_id, gstring_lookup_cache)
18409 (composition_gstring_put_cache):
18410 * composite.h (struct composition.hash_index):
18411 * dispextern.h (struct image.hash):
18412 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
18413 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
18414 (hashfn_equal, hashfn_user_defined, make_hash_table)
18415 (maybe_resize_hash_table, hash_lookup, hash_put)
18416 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18417 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18418 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18419 * image.c (make_image, search_image_cache, lookup_image)
18420 (xpm_put_color_table_h):
18421 * lisp.h (struct Lisp_Hash_Table):
18422 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18423 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18424 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18425 * alloc.c (allocate_vectorlike):
18426 Check for overflow in vector size calculations.
18427 * ccl.c (ccl_driver):
18428 Check for overflow when converting EMACS_INT to int.
18429 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18430 need to be updated by these changes.
18431 * fns.c (make_hash_table, maybe_resize_hash_table):
18432 Check for integer overflow with large hash tables.
18433 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18434 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18435 (SXHASH_REDUCE): New macro.
18436 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18437 Use it instead of discarding useful hash info with large hash values.
18438 (sxhash_float): New function.
18439 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18440 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18441 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18442 Rewrite to use FIXNUM_BITS, as this simplifies things.
18443 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18444 Adjust signatures to match updated version of code.
18445 (consing_since_gc): Now EMACS_INT, since a single hash table can
18446 use more than INT_MAX bytes.
18448 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18450 Make it possible to build with GCC-4.6+ -O2 -flto.
18452 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18454 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18456 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18457 Call minibuffer-inactive-mode.
18459 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18461 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18462 Update dependencies.
18464 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18466 * data.c (init_data): Remove code for UTS, this system is not
18469 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18471 Don't force ./temacs to start in terminal mode.
18473 * frame.c (make_initial_frame): Initialize faces in all cases, not
18474 only when CANNOT_DUMP is defined.
18475 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18477 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18479 * dispnew.c (add_window_display_history): Use const for the string
18480 pointer. Remove declaration, not needed.
18482 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18484 Use 'inline', not 'INLINE'.
18485 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18486 * alloc.c, fontset.c (INLINE): Remove.
18487 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18488 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18489 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18490 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18491 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18493 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18495 Make it possible to run ./temacs.
18497 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18498 syms_of_callproc does the same thing. Remove test for
18499 "initialized", do it in the caller.
18500 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18502 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18504 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18505 (read_minibuf): Use get_minibuffer.
18506 (syms_of_minibuf): Use DEFSYM.
18507 (Qmetadata): New var.
18508 * data.c (Qbuffer): Don't make it static.
18509 (syms_of_data): Use DEFSYM.
18511 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18513 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18514 (CCL_CODE_MIN): New macro.
18516 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18518 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18520 * eval.c (Qdebug): Now static.
18521 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18522 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18523 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18525 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18527 * image.c: Various fixes to ImageMagick code comments.
18528 (Fimagemagick_types): Doc fix.
18530 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18532 Minor fixes prompted by GCC 4.6.0 warnings.
18534 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18536 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18537 (x_clipboard_manager_save_all): Move extern decl to ...
18538 * xterm.h: ... here, so that it can be checked for consistency.
18540 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18542 * xselect.c (x_clipboard_manager_save_frame)
18543 (x_clipboard_manager_save_all): New functions.
18544 (Fx_clipboard_manager_save): Lisp function deleted.
18546 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18547 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18549 * xterm.h: Update prototype.
18551 2011-05-28 William Xu <william.xwl@gmail.com>
18553 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18554 exiting (Bug#8239).
18556 2011-05-28 Jim Meyering <meyering@redhat.com>
18558 Avoid a sign-extension bug in crypto_hash_function.
18559 * fns.c (to_uchar): Define.
18560 (crypto_hash_function): Use it to convert some newly-signed
18561 variables to unsigned, to avoid sign-extension bugs. For example,
18562 without this change, (md5 "truc") would evaluate to
18563 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18564 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18565 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18567 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18569 Integer overflow fixes.
18571 * dbusbind.c: Serial number integer overflow fixes.
18572 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18573 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18574 to hold a serial number that is too large for a fixnum.
18575 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18576 Check for serial numbers out of range. Decode any serial number
18577 that was so large that it became a float. (Bug#8722)
18579 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18580 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18581 Use XFASTINT rather than XUINT when numbers are nonnegative.
18582 (xd_append_arg, Fdbus_method_return_internal):
18583 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18584 arguments, check that Lisp number is nonnegative, rather than
18585 silently wrapping negative numbers around. (Bug#8722)
18586 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18589 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18591 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18593 ccl: Add integer overflow checks.
18594 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18595 (IN_INT_RANGE): New macros.
18596 (ccl_driver): Use them to check for integer overflow when
18597 decoding a CCL program. Many of the new checks are whether XINT (x)
18598 fits in int; it doesn't always, on 64-bit hosts. The new version
18599 doesn't catch all possible integer overflows, but it's an
18600 improvement. (Bug#8719)
18602 * alloc.c (make_event_array): Use XINT, not XUINT.
18603 There's no need for unsigned here.
18605 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18606 This follows up to the 2011-05-06 change that substituted uintptr_t
18607 for EMACS_INT. This case wasn't caught back then.
18609 Rework Fformat to avoid integer overflow issues.
18610 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18611 now (part of C89). Include <verify.h>.
18612 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18613 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18614 (Fformat): Avoid the prepass trying to compute sizes; it was only
18615 approximate and thus did not catch overflow reliably. Instead, walk
18616 through the format just once, formatting and computing sizes as we go,
18617 checking for integer overflow at every step, and allocating a larger
18618 buffer as needed. Keep track separately whether the format is
18619 multibyte. Keep only the most-recently calculated precision, rather
18620 than them all. Record whether each argument has been converted to
18621 string. Use EMACS_INT, not int, for byte and char and arg counts.
18622 Support field widths and precisions larger than INT_MAX. Avoid
18623 sprintf's undefined behavior with conversion specifications such as %#d
18624 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18625 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18626 formatting out-of-range floating point numbers with int
18627 formats. (Bug#8668)
18629 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18631 * data.c: Avoid integer truncation in expressions involving floats.
18632 * data.c: Include <intprops.h>.
18633 (arith_driver): When there's an integer overflow in an expression
18634 involving floating point, convert the integers to floating point
18635 so that the resulting value does not suffer from catastrophic
18636 integer truncation. For example, on a 64-bit host (* 4
18637 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18638 Do not rely on undefined behavior after integer overflow.
18640 merge count_size_as_multibyte, parse_str_to_multibyte
18641 * character.c, character.h (count_size_as_multibyte):
18642 Rename from parse_str_to_multibyte; all uses changed.
18643 Check for integer overflow.
18644 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18645 since it's now a duplicate of the other. This is more of
18646 a character than a buffer op, so better that it's in character.c.
18647 * fns.c, print.c: Adjust to above changes.
18649 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18651 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18653 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18655 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18656 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18657 (x_clipboard_manager_save): Now static.
18658 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18660 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18661 (crypto_hash_function): Now static.
18662 Fix pointer signedness problems. Avoid unnecessary initializations.
18664 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18666 * termhooks.h (Vselection_alist): Make it terminal-local.
18668 * terminal.c (create_terminal): Initialize it.
18670 * xselect.c: Support for clipboard managers.
18671 (Vselection_alist): Move to termhooks.h as terminal-local var.
18672 (LOCAL_SELECTION): New macro.
18673 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18674 (symbol_to_x_atom): Remove gratuitous arg.
18675 (x_handle_selection_request, lisp_data_to_selection_data)
18676 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18677 (x_own_selection, x_get_local_selection, x_convert_selection):
18678 New arg, specifying work frame. Use terminal-local Vselection_alist.
18679 (some_frame_on_display): Delete unused function.
18680 (Fx_own_selection_internal, Fx_get_selection_internal)
18681 (Fx_disown_selection_internal, Fx_selection_owner_p)
18682 (Fx_selection_exists_p): New optional frame arg.
18683 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18684 (x_handle_selection_clear): Don't treat other terminals with the
18685 same keyboard specially. Use the terminal-local Vselection_alist.
18686 (x_clear_frame_selections): Use Frun_hook_with_args.
18688 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18690 * xterm.h: Add support for those atoms.
18692 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18694 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18695 (converted_selections, conversion_fail_tag): New global variables.
18696 (x_selection_request_lisp_error): Free the above.
18697 (x_get_local_selection): Remove unnecessary code.
18698 (x_reply_selection_request): Args changed; handle arbitrary array
18699 of converted selections stored in converted_selections.
18700 Separate the XChangeProperty and SelectionNotify steps.
18701 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18702 (x_convert_selection): New function.
18703 (x_handle_selection_event): Simplify.
18704 (x_get_foreign_selection): Don't ignore incoming requests while
18705 waiting for an answer; this will fail when we implement
18706 SAVE_TARGETS, and seems unnecessary anyway.
18707 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18708 (Vx_sent_selection_functions): Doc fix.
18710 2011-05-26 Leo Liu <sdl.web@gmail.com>
18712 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18714 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18716 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18718 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18719 for fringe update if it has periodic bitmap.
18720 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18721 and fringe_bitmap_periodic_p.
18723 * fringe.c (get_fringe_bitmap_data): New function.
18724 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18725 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18726 row. Mark glyph row for fringe update if periodicity changed.
18728 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18729 for fringe update unless it has periodic bitmap.
18731 2011-05-25 Kenichi Handa <handa@m17n.org>
18733 * xdisp.c (get_next_display_element): Set correct it->face_id for
18734 a static composition.
18736 2011-05-24 Leo Liu <sdl.web@gmail.com>
18739 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18741 * fns.c (crypto_hash_function, Fsha1): New function.
18742 (Fmd5): Use crypto_hash_function.
18743 (syms_of_fns): Add Ssha1.
18745 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18747 * gnutls.c: Remove unused macros.
18748 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18749 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18750 Remove macros that are defined and never used.
18751 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18753 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18755 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18756 (Fx_get_selection_internal): Minor cleanup.
18757 (Fx_own_selection_internal): Rename arguments for consistency with
18760 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18762 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18764 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18766 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18768 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18770 * dispnew.c (scrolling_window): Don't exclude the case that the
18771 last enabled row in the desired matrix touches the bottom boundary.
18773 2011-05-21 Glenn Morris <rgm@gnu.org>
18775 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18776 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18777 and add some more files.
18779 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18781 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18782 report_file_error introduced by the change from 2011-05-07.
18784 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18786 * systime.h (Time): Define only if emacs is defined.
18787 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18788 where the include path doesn't have X11/X.h by default. See
18789 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18791 2011-05-20 Kenichi Handa <handa@m17n.org>
18793 * composite.c (find_automatic_composition): Fix previous change.
18795 2011-05-20 Glenn Morris <rgm@gnu.org>
18797 * lisp.mk: New file, split from Makefile.in.
18798 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18799 (shortlisp): Remove.
18800 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18802 2011-05-19 Glenn Morris <rgm@gnu.org>
18804 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18805 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18806 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18807 (lisp): Set the order to that of loadup.el.
18808 (shortlisp): Make it a copy of $lisp.
18809 (SOME_MACHINE_LISP): Remove.
18810 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18811 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18813 2011-05-18 Kenichi Handa <handa@m17n.org>
18815 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18816 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18817 (find_automatic_composition): Mostly rewrite for efficiency.
18819 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18821 * makefile.w32-in: Update dependencies.
18823 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18825 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18826 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18828 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18830 Fix some integer overflow issues, such as string length overflow.
18832 * insdel.c (count_size_as_multibyte): Check for string overflow.
18834 * character.c (lisp_string_width): Check for string overflow.
18835 Use EMACS_INT, not int, for string indexes and lengths; in
18836 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18837 the resulting string length overflows an EMACS_INT; instead,
18838 report a string overflow if no precision given. When checking for
18839 precision exhaustion, use a check that cannot possibly have
18840 integer overflow. (Bug#8675)
18841 * character.h (lisp_string_width): Adjust to new signature.
18843 * alloc.c (string_overflow): New function.
18844 (Fmake_string): Use it. This doesn't change behavior, but saves
18845 a few bytes and will simplify future changes.
18846 * character.c (string_escape_byte8): Likewise.
18847 * lisp.h (string_overflow): New decl.
18849 Fixups, following up to the user-interface timestamp change.
18850 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18851 for UI timestamps, instead of unsigned long.
18852 * msdos.c (mouse_get_pos): Likewise.
18853 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18854 * w32gui.h (Time): Define by including "systime.h" rather than by
18855 declaring it ourselves. (Bug#8664)
18857 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18858 * image.c (clear_image_cache): Likewise.
18860 * term.c (term_mouse_position): Don't assume time_t wraparound.
18862 Be more systematic about user-interface timestamps.
18863 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18864 and sometimes 'EMACS_UINT', to represent these timestamps.
18865 This change causes it to use 'Time' uniformly, as that's what X uses.
18866 This makes the code easier to follow, and makes it easier to catch
18867 integer overflow bugs such as Bug#8664.
18868 * frame.c (Fmouse_position, Fmouse_pixel_position):
18869 Use Time, not unsigned long, for user-interface timestamps.
18870 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18871 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18872 * keyboard.h (last_event_timestamp): Likewise.
18873 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18874 * menu.h (xmenu_show): Likewise.
18875 * term.c (term_mouse_position): Likewise.
18876 * termhooks.h (struct input_event.timestamp): Likewise.
18877 (struct terminal.mouse_position_hook): Likewise.
18878 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18879 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18880 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18881 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18882 what it was before.
18883 * menu.h, termhooks.h: Include "systime.h", for Time.
18885 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18886 Don't assume that the difference between two unsigned long values
18887 can fit into an integer. At this point, we know button_down_time
18888 <= event->timestamp, so the difference must be nonnegative, so
18889 there's no need to cast the result if double-click-time is
18890 nonnegative, as it should be; check that it's nonnegative, just in
18891 case. This bug is triggered when events are more than 2**31 ms
18892 apart (about 25 days). (Bug#8664)
18894 * xselect.c (last_event_timestamp): Remove duplicate decl.
18895 (x_own_selection): Remove needless cast to unsigned long.
18897 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18898 that always fit in int. Use a sentinel instead of a counter, to
18899 avoid a temp and to allay GCC's concerns about possible int overflow.
18900 * frame.h (struct frame): Use int for menu_bar_items_used
18901 instead of EMACS_INT, since it always fits in int.
18903 * menu.c (grow_menu_items): Check for int overflow.
18905 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18907 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18908 Before, the code was not consistent. These values cannot exceed
18909 2**31 - 1 so there's no need to make them unsigned.
18910 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18911 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18912 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18914 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18916 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18917 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18918 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18919 presumably because the widths might not match.
18921 * window.c (size_window): Avoid needless test at loop start.
18923 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18925 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18927 2011-05-12 Drew Adams <drew.adams@oracle.com>
18929 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18931 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18933 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18934 `width' to `bar_area_x' and `bar_area_width', respectively.
18935 (x_scroll_run): Take account of fringe background extension.
18937 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18938 Rename local vars `left' and `width' to `bar_area_x' and
18939 `bar_area_width', respectively.
18940 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18941 background extension.
18943 2011-05-10 Jim Meyering <meyering@redhat.com>
18945 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18947 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18949 * image.c (Finit_image_library): Return t for built-in image types,
18950 like pbm and xbm. (Bug#8640)
18952 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18954 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18956 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18958 * w32console.c (Fset_screen_color): Doc fix.
18959 (Fget_screen_color): New function.
18960 (syms_of_ntterm): Defsubr it.
18962 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18963 unlink the temporary file if Fcall_process didn't create it in the
18965 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18966 child process will be redirected to a file specified with `:file'.
18967 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18968 cue to call_process_cleanup not to close that handle.
18970 2011-05-07 Ben Key <bkey76@gmail.com>
18972 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18973 one of two shell specific rules, either bootstrap-temacs-CMD or
18974 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18975 to the previous implementation of the bootstrap-temacs rule.
18976 The bootstrap-temacs-CMD rule is similar to the previous
18977 implementation of the bootstrap-temacs rule except that it
18978 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18981 These changes, along with some changes to nt/configure.bat,
18982 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18983 earlier fix to add support for --cflags and --ldflags options
18984 that include quotes so that it works whether make uses cmd or
18987 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18989 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18990 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18992 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18993 a string. Handle both cases.
18994 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18995 (Fdbus_register_method): Use Qinvalid_function.
18997 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18999 * makefile.w32-in: Update dependencies.
19000 (LISP_H): Add inttypes.h and stdin.h.
19001 (PROCESS_H): Add unistd.h.
19003 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19005 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19006 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19008 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19010 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19012 * term.c (vfatal): Remove stray call to va_end.
19013 It's not needed and the C Standard doesn't allow it here anyway.
19015 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19016 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19018 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19021 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19023 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19025 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19027 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19029 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19031 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19032 * charset.c (Fdefine_charset_internal): Don't initialize
19033 charset.code_space[15]. The value was garbage, on hosts with
19034 32-bit int (Bug#8600).
19036 * lread.c (read_integer): Be more consistent with string-to-number.
19037 Use string_to_number to do the actual conversion; this avoids
19038 rounding errors and fixes some other screwups. Without this fix,
19039 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19040 (digit_to_number): Move earlier, for benefit of read_integer.
19041 Return -1 if the digit is out of range for the base, -2 if it is
19042 not a digit in any supported base. (Bug#8602)
19044 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19046 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19047 to match comment at start of function. This also removes a
19048 GCC warning about overflow in a 32+64-bit port.
19050 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19052 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19053 Reported by Stefan Monnier in
19054 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19055 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19056 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19058 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19059 (EMACS_UINTPTR): Likewise, with uintptr_t.
19061 * lisp.h: Prefer 64-bit EMACS_INT if available.
19062 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19063 on 32-bit hosts that have 64-bit int, so that they can access
19065 However, temporarily disable this change unless the temporary
19066 symbol WIDE_EMACS_INT is defined.
19068 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19070 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19071 This removes an assumption that EMACS_INT and long are the same
19072 width as pointers. The assumption is true for Emacs porting targets
19073 now, but we want to make other targets possible.
19074 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19075 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19076 In the rest of the code, change types of integers that hold casted
19077 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19078 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19079 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19080 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19081 No need to cast type when ORing.
19082 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19083 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19084 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19085 assume EMACS_INT is the same width as char *.
19086 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19087 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19088 Remove no-longer-needed casts.
19089 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19090 (xg_tool_bar_help_callback, xg_make_tool_item):
19091 Use EMACS_INTPTR to hold an integer
19092 that will be cast to void *; this can avoid a GCC warning
19093 if EMACS_INT is not the same width as void *.
19094 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19095 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19096 (current_message_1, set_message_1):
19097 Use a local to convert to proper width without a cast.
19098 * xmenu.c (dialog_selection_callback): Likewise.
19100 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19101 Also, don't assume VALBITS / RAND_BITS is less than 5,
19102 and don't rely on undefined behavior when shifting a 1 left into
19104 * lisp.h (get_random): Change signature to match.
19106 * lread.c (hash_string): Use size_t, not int, for hash computation.
19107 Normally we prefer signed values; but hashing is special, because
19108 it's better to use unsigned division on hash table sizes so that
19109 the remainder is nonnegative. Also, size_t is the natural width
19110 for hashing into memory. The previous code used 'int', which doesn't
19111 retain enough info to hash well into very large tables.
19112 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19114 * dbusbind.c: Don't possibly lose pointer info when converting.
19115 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19116 Use XPNTR rather than XHASH, so that the high-order bits of
19117 the pointer aren't lost when converting through void *.
19119 * eval.c (Fautoload): Don't double-shift a pointer.
19121 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

19130 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19133 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19135 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:

19155 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19156 Remove unused parameter `fildes'.
19157 * process.c (read_process_output, send_process): Don't pass it.
19159 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19161 Fix previous change: the library cache is defined in w32.c.
19162 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19163 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

19198 (w32_delayed_load): Move from image.c. When loading a library, record
19199 its filename in the :loaded-from property of the library id.

19201 Initialize and staticpro them.
19202 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19204 * process.c: Include lisp.h before w32.h, not after.
19205 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19206 instead of gnutls_record_check_pending.
19208 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19210 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19212 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19213 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19216 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19218 * xterm.c (x_set_frame_alpha): Do not set property on anything
19219 else than FRAME_X_OUTER_WINDOW (Bug#8608).

19223 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19225 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19227 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

19253 (Fcall_process_region): Ditto.
19255 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19257 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19258 rather than `XVECTOR (FOO)->size'.
19260 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19261 inttypes.h, as a gnulib replacement is used if it not available in
19264 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19266 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19267 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19268 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19270 * coding.c (coding_alloc_by_realloc): Error out if destination
19271 will grow beyond MOST_POSITIVE_FIXNUM.
19272 (decode_coding_emacs_mule): Abort if there isn't enough place in
19273 charbuf for the composition carryover bytes. Reserve an extra
19274 space for up to 2 characters produced in a loop.

19276 charbuf for the composition carryover bytes.
19278 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19280 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19281 aborting when %lld or %lll format is passed.

19283 %llo or %llx format is passed. (Bug#8545)
19285 * window.c (window_scroll_line_based): Use a marker instead of
19286 simple variables to record original value of point. (Bug#7952)
19288 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19289 produced by %s or %c overflows available buffer space. (Bug#8545)
19291 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19293 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19296 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19298 * w32.c (init_environment): Warn about defaulting HOME to C:\.

19302 * keyboard.c (Qdelayed_warnings_hook): Define.
19303 (command_loop_1): Run `delayed-warnings-hook'
19304 if Vdelayed_warnings_list is non-nil.
19305 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19306 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19308 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19310 * doprnt.c (doprnt): Don't return value smaller than the buffer
19311 size if the message was truncated. (Bug#8545).
19313 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19315 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

19322 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19324 * makefile.w32-in: Update dependencies.
19326 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19328 Improve `doprnt' and its usage. (Bug#8545)
19329 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19330 `format_end'. Remove support for %l as a conversion specifier.
19331 Don't use xrealloc. Improve diagnostics when the %l size modifier
19332 is used. Update the commentary.
19334 * eval.c (verror): Simplify calculation of size_t.
19336 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19339 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19341 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19344 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19346 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19347 This makes this file independent of the recent pseudovector change.
19349 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19351 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19353 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19354 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19355 Remove unused local.
19356 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19358 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19359 GCC 4.6.0 optimizes based on type-based alias analysis.
19360 For example, if b is of type struct buffer * and v of type struct
19361 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19362 != &v->size, and therefore "v->size = 1; b->size = 2; return
19363 v->size;" must therefore return 1. This assumption is incorrect
19364 for Emacs, since it type-puns struct Lisp_Vector * with many other
19365 types. To fix this problem, this patch adds a new type struct
19366 vectorlike_header that documents the constraints on layout of vectors
19367 and pseudovectors, and helps optimizing compilers not get fooled
19368 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19369 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19370 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19372 (XSETPVECTYPE): Rewrite in terms of new macro.
19373 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19374 This is a bit clearer, and further avoids the possibility of
19375 undesirable aliasing.
19376 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19377 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19378 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19379 since Lisp_Subr is a special case (no "next" field).
19380 (ASIZE): Now uses header.size rather than size.
19381 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19382 to avoid the hassle of writing XVECTOR (foo)->header.size.
19383 (struct vectorlike_header): New type.
19384 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19385 object, to help avoid aliasing.
19386 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19387 (SUBRP): Likewise, since Lisp_Subr is a special case.
19388 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19389 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19390 (struct Lisp_Hash_Table): Combine first two members into a single
19391 struct vectorlike_header member. All uses of "size" and "next" members
19392 changed to be "header.size" and "header.next".
19393 * buffer.h (struct buffer): Likewise.
19394 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19395 * frame.h (struct frame): Likewise.
19396 * process.h (struct Lisp_Process): Likewise.
19397 * termhooks.h (struct terminal): Likewise.
19398 * window.c (struct save_window_data, struct saved_window): Likewise.
19399 * window.h (struct window): Likewise.
19400 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19401 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19402 * buffer.c (init_buffer_once): Likewise.
19403 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19405 * process.c (Fformat_network_address): Use local var for size,
19408 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19410 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19411 * data.c (atof): Remove decl; no longer used or needed.
19412 (digit_to_number): Move to lread.c.
19413 (Fstring_to_number): Use new string_to_number function, to be
19414 consistent with how the Lisp reader treats infinities and NaNs.
19415 Do not assume that floating-point numbers represent EMACS_INT
19416 without losing information; this is not true on most 64-bit hosts.
19417 Avoid double-rounding errors, by insisting on integers when
19418 parsing non-base-10 numbers, as the documentation specifies.
19419 * lisp.h (string_to_number): New decl, replacing ...
19420 (isfloat_string): Remove.
19421 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19422 (read1): Do not accept +. and -. as integers; this
19423 appears to have been a coding error. Similarly, do not accept
19424 strings like +-1e0 as floating point numbers. Do not report
19425 overflow for integer overflows unless the base is not 10 which
19426 means we have no simple and reliable way to continue.
19427 Break out the floating-point parsing into a new
19428 function string_to_number, so that Fstring_to_number parses
19429 floating point numbers consistently with the Lisp reader.
19430 (digit_to_number): Move here from data.c. Make it static inline.
19431 (E_CHAR, EXP_INT): Remove, replacing with ...
19432 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19433 (string_to_number): New function, replacing isfloat_string.
19434 This function checks for valid syntax and produces the resulting
19435 Lisp float number too. Rework it so that string-to-number
19436 no longer mishandles examples like "1.0e+". Use strtoumax,
19437 so that overflow for non-base-10 numbers is reported only when
19438 there's no portable and simple way to convert to floating point.
19440 * textprop.c (set_text_properties_1): Rewrite for clarity,
19441 and to avoid GCC warning about integer overflow.
19443 * intervals.h (struct interval): Use EMACS_INT for members
19444 where EMACS_UINT might cause problems. See
19445 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19446 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19447 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19449 (offset_intervals): Tell GCC not to worry about length overflow
19450 when negating a negative length.
19452 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19453 (overrun_check_free): Likewise.
19455 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19456 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19459 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19460 (gnutls_make_error): Rename local to avoid shadowing.
19461 (gnutls_emacs_global_deinit): ifdef out; not used.
19462 (Fgnutls_boot): Use const for pointer to readonly storage.
19463 Comment out unused local. Fix pointer signedness problems.
19465 * lread.c (openp): Don't stuff size_t into an 'int'.
19466 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19467 about possible signed overflow.
19469 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19470 (GDK_KEY_g): Don't define if already defined.
19471 (xg_prepare_tooltip): Avoid pointer signedness problem.
19472 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19474 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19475 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19477 * xfns.c (Fx_window_property): Simplify a bit,
19478 to make a bit faster and to avoid GCC 4.6.0 warning.
19479 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19481 * fns.c (internal_equal): Don't assume size_t fits in int.
19483 * alloc.c (compact_small_strings): Tighten assertion a little.
19485 Replace pEd with more-general pI, and fix some printf arg casts.
19486 * lisp.h (pI): New macro, generalizing old pEd macro to other
19487 conversion specifiers. For example, use "...%"pI"d..." rather
19488 than "...%"pEd"...".
19489 (pEd): Remove. All uses replaced with similar uses of pI.
19490 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19491 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19492 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19493 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19494 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19495 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19496 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19498 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19499 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19500 * print.c (safe_debug_print, print_object): Likewise.
19501 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19503 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19504 avoiding the 0 flag, which is not portable.
19505 * process.c (Fmake_network_process): Use pI to avoid cast.
19506 * region-cache.c (pp_cache): Likewise.
19507 * xdisp.c (decode_mode_spec): Likewise.
19508 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19509 behavior on 64-bit hosts with printf arg.
19510 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19511 (x_stop_queuing_selection_requests): Likewise.
19512 (x_get_window_property): Don't truncate byte count to an 'int'
19515 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19516 here, since it parses constructs like leading '-' and spaces,
19517 which are not wanted; and it overflows with large numbers.
19518 Instead, simply match F[0-9]+, which is what is wanted anyway.

19524 plus offsetof, to remove unportable assumptions about struct layout.
19525 These assumptions hold on all porting targets that I know of, but
19526 they are not guaranteed, they're easy to remove, and removing them
19527 makes further changes easier.
19529 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19530 This doesn't fix a bug but makes the code clearer.
19531 (string_overrun_cookie): Now const. Use initializers that

19534 can cause Emacs to crash when string overrun checking is enabled.
19535 (allocate_buffer): Don't assume sizeof (struct buffer) is a

19574 supported by the function. Use SAFE_ALLOCA instead of always
19577 * eval.c (verror): Don't limit the buffer size at size_max-1, that

19705 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19706 to `error' in error message about FINAL_CHAR argument. Make sure
19707 FINAL_CHAR is a character, and use %c when it is passed as
19708 argument to `error'.
19710 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19712 * s/ms-w32.h (localtime): Redirect to sys_localtime.
19714 * w32.c: Include <time.h>.

19898 ns_descriptor_to_entity that were caused by using free to
19899 deallocate memory blocks that were allocated by xmalloc (via

19920 (emacs_read, emacs_write): Use it.
19921 * process.c (send_process): Adjust to the new signatures of
19922 emacs_write and emacs_gnutls_write. Do not attempt to store

20410 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20411 argument, local variables, and return value.
20413 * lisp.h: Update prototypes of emacs_write and emacs_read.
20415 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20417 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20419 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20421 Fix more problems found by GCC 4.6.0's static checks.
20423 * xdisp.c (vmessage): Use a better test for character truncation.
20425 * charset.c (load_charset_map): <, not <=, for optimization,
20426 and to avoid potential problems with integer overflow.
20427 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20428 * casetab.c (set_identity, shuffle): Likewise.
20429 * editfns.c (Fformat): Likewise.
20430 * syntax.c (skip_chars): Likewise.
20432 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20433 This also lets GCC 4.6.0 generate slightly better loop code.
20435 * callint.c (Fcall_interactively): <, not <=, for optimization.
20436 (Fcall_interactively): Count the number of arguments produced,
20437 not the number of arguments given. This is simpler and lets GCC
20438 4.6.0 generate slightly better code.
20440 * ftfont.c: Distingish more carefully between FcChar8 and char.
20441 The previous code passed unsigned char * to a functions like
20442 strlen and xstrcasecmp that expect char *, which does not
20443 conform to the C standard.
20444 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20445 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20446 char * when the C standard requires it.
20448 * keyboard.c (read_char): Remove unused var.
20450 * eval.c: Port to Windows vsnprintf (Bug#8435).
20451 Include <limits.h>.
20452 (SIZE_MAX): Define if the headers do not.
20453 (verror): Do not give up if vsnprintf returns a negative count.
20454 Instead, grow the buffer. This ports to Windows vsnprintf, which
20455 does not conform to C99. Problem reported by Eli Zaretskii.
20456 Also, simplify the allocation scheme, by avoiding the need for
20457 calling realloc, and removing the ALLOCATED variable.
20459 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20461 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20462 But keep the doprint source code for now, as we might revamp it
20463 and use it again (Bug#8435).
20464 * lisp.h (doprnt): Remove.
20465 * Makefile.in (base_obj): Remove doprnt.o.
20466 * deps.mk (doprnt.o): Remove.
20468 error: Print 32- and 64-bit integers portably (Bug#8435).
20469 Without this change, on typical 64-bit hosts error ("...%d...", N)
20470 was used to print both 32- and 64-bit integers N, which relied on
20471 undefined behavior.
20472 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20473 * lisp.h (error, verror): Mark as printf-like functions.
20474 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20475 Report overflow in size calculations when allocating printf buffer.
20476 Do not truncate output string at its first null byte.
20477 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20478 Truncate the output at a character boundary, since vsnprintf does not
20480 * charset.c (check_iso_charset_parameter): Convert internal
20481 character to string before calling 'error', since %c now has the
20483 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20484 overflow when computing char to be passed to 'error'. Do not
20485 pass Lisp_Object to 'error'; pass the integer instead.
20486 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20487 formatted with plain %d.
20489 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20491 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20493 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20495 * xterm.c (x_catch_errors): Remove duplicate declaration.
20497 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20499 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20501 2011-04-10 Jim Meyering <meyering@redhat.com>
20503 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20504 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20505 return ssize_t not "int", and use size_t as the buffer length.
20506 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20507 * gnutls.h: Update declarations.
20508 * process.c (read_process_output): Use ssize_t, to match.
20509 (send_process): Likewise.
20511 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20513 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20515 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20517 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20518 Use unsigned char, to match FcChar8 type definition.
20520 * xterm.c (handle_one_xevent):
20521 * xmenu.c (create_and_show_popup_menu):
20522 * xselect.c (x_decline_selection_request)
20523 (x_reply_selection_request): Avoid type-punned deref of X events.
20525 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20527 Fix some uses of `int' instead of EMACS_INT.
20528 * search.c (string_match_1, fast_string_match)
20529 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20530 (scan_buffer, find_next_newline_no_quit)
20531 (find_before_next_newline, search_command, Freplace_match)
20532 (Fmatch_data): Make some `int' variables be EMACS_INT.
20534 * xdisp.c (display_count_lines): 3rd argument and return value now
20535 EMACS_INT. All callers changed.
20536 (pint2hrstr): Last argument is now EMACS_INT.
20538 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20539 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20540 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20541 (decode_coding_utf_16, decode_coding_emacs_mule)
20542 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20543 (decode_coding_ccl, decode_coding_charset)
20544 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20545 (decode_coding_iso_2022, decode_coding_emacs_mule)
20546 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20547 <char_offset, last_offset>: Declare EMACS_INT.
20548 (encode_coding_utf_8, encode_coding_utf_16)
20549 (encode_coding_emacs_mule, encode_invocation_designation)
20550 (encode_designation_at_bol, encode_coding_iso_2022)
20551 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20552 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20554 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20555 (encode_invocation_designation): Last argument P_NCHARS is now
20557 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20558 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20560 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20563 * ccl.c (Fccl_execute_on_string): Declare some variables
20566 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20568 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20570 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20572 * process.c (Fformat_network_address): Doc fix.
20574 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20576 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20578 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20580 * keyboard.c (read_char): Call Lisp function help-form-show,
20581 instead of using internal_with_output_to_temp_buffer.
20582 (Qhelp_form_show): New var.
20583 (syms_of_keyboard): Use DEFSYM macro.
20585 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20587 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20589 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20591 * process.c (Flist_processes): Remove to Lisp.
20592 (list_processes_1): Delete.

20598 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20600 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20602 Fix more problems found by GCC 4.6.0's static checks.
20604 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20606 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20608 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20610 * xdisp.c (vmessage): Mark as a printf-like function.
20612 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20614 * sound.c (sound_warning): Don't crash if arg contains a printf format.

20619 to system-supplied API.
20621 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20623 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20624 This avoids several warnings with gcc -Wstrict-overflow.
20625 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20626 directly, rather than having caller test rule sign. This avoids
20627 some unnecessary tests.
20628 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20629 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20630 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20632 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20633 (xfont_open): Avoid unnecessary tests.
20635 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20637 * composite.h, composite.c (composition_gstring_put_cache):
20638 Use EMACS_INT, not int, for length.

20641 breaking out part of COMPOSITION_DECODE_RULE.
20642 (COMPOSITION_DECODE_RULE): Use it.

20644 by using the new macro.
20646 * textprop.c (set_text_properties_1): Change while to do-while,
20647 since the condition is always true at first.
20649 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20650 (interval_deletion_adjustment): Return unsigned value.
20653 * process.c (list_processes_1, create_pty, read_process_output):

20665 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20666 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20667 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20669 * print.c (print_error_message): Avoid int overflow.
20671 * font.c (font_list_entities): Redo for clarity,
20672 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20674 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20675 (font_score): Avoid potential overflow in diff calculation.
20677 * fns.c (substring_both): Remove var that is set but not used.
20678 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20680 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20682 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20683 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20684 can always succeed if overflow has undefined behavior.
20686 * search.c (boyer_moore, wordify): Remove vars set but not used.
20687 (wordify): Omit three unnecessary tests.
20689 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20690 All callers changed. This avoids the need for an unused var.
20692 * casefiddle.c (casify_region): Remove var that is set but not used.
20694 * dired.c (file_name_completion): Remove var that is set but not used.

20704 * buffer.c (Fprevious_overlay_change): Remove var that is set
20707 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20708 Remove vars that are set but not used.
20709 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20710 (timer_check_2): Mark vars as initialized.
20712 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20714 * image.c (lookup_image): Remove var that is set but not used.
20715 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20717 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20718 that are set but not used.
20720 * xfns.c (make_invisible_cursor): Don't return garbage
20721 if XCreateBitmapFromData fails (Bug#8410).
20723 * xselect.c (x_get_local_selection, x_handle_property_notify):
20724 Remove vars that are set but not used.
20726 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

20736 (map_tty_color) [!defined MSDOS]: Likewise.
20738 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20740 * coding.c: Remove vars that are set but not used.
20741 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20742 All callers changed.

20744 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20745 (decode_coding_charset): Remove vars that are set but not used.
20747 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20748 that is set but not used.
20750 * print.c (print_object): Remove var that is set but not used.
20752 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20753 The gnulib version avoids calling malloc in the usual case,
20754 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20755 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20756 * filelock.c (current_lock_owner): Likewise.
20757 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

20761 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20762 ../lib/careadlinkat.h.
20764 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20766 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20767 first non-nil return value).

20781 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20782 and thereabouts. All callers changed.
20783 (get_per_char_metric): Remove parameter `f', unused since
20784 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20788 do not dereference NULL upon failed strdup
20789 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20790 (ns_get_family): Likewise.
20792 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

20867 Limit scrolling to 100 screen lines.
20868 (redisplay_window): Even when falling back on "recentering",
20869 position point in the window according to scroll-conservatively,
20870 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20872 (try_scrolling): When point is above the window, allow searching
20873 as far as scroll_max, or one screenful, to compute vertical
20874 distance from PT to the scroll margin position. This prevents
20875 try_scrolling from unnecessarily failing when
20876 scroll-conservatively is set to a value slightly larger than the
20877 window height. Clean up the case of PT below the margin at bottom
20878 of window: scroll_max can no longer be INT_MAX. When aggressive
20879 scrolling is in use, don't let point enter the opposite scroll
20880 margin as result of the scroll.
20881 (syms_of_xdisp) <scroll-conservatively>: Document the
20882 threshold of 100 lines for never-recentering scrolling.
20884 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20886 * dispextern.h (move_it_by_lines):
20887 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20888 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20889 (message_log_check_duplicate): Remove parameters `prev_bol' and
20890 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20891 (redisplay_internal): Remove parameter `preserve_echo_area',
20892 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20894 * indent.c (Fvertical_motion):
20895 * window.c (window_scroll_pixel_based, Frecenter):
20896 Don't pass `need_y_p' to `move_it_by_lines'.
20898 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20900 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20901 steal a few bits to be more compact.
20902 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20903 Remove unneeded casts.
20905 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20907 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20909 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20910 binding" message (bug#7967).
20912 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20914 Fix more problems found by GCC 4.6.0's static checks.
20916 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20917 Remove unused local var.
20919 * editfns.c (Fmessage_box): Remove unused local var.
20921 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20922 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20923 Omit unused local vars.
20924 * window.c (shrink_windows): Omit unused local var.
20925 * menu.c (digest_single_submenu): Omit unused local var.
20926 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20927 Omit unused local var.
20929 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20930 Don't assume string length fits in int.
20931 (keyremap_step, read_key_sequence): Use size_t for sizes.
20932 (read_key_sequence): Don't check last_real_key_start redundantly.
20934 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20935 instead of alloca (Bug#8344).
20937 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20938 (Fbacktrace_frame): Don't assume nframes fits in int.
20940 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20942 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20945 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20947 * cm.c (calccost): Turn while-do into do-while, for clarity.
20949 * keyboard.c (syms_of_keyboard): Use the same style as later
20950 in this function when indexing through an array. This also
20951 works around GCC bug 48267.
20953 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20955 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20957 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20958 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20960 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20961 This avoids undefined behavior on integer overflow, and is a bit
20962 more convenient anyway since it is compared to a size_t variable.
20964 Variadic C functions now count arguments with size_t, not int.
20965 This avoids an unnecessary limitation on 64-bit machines, which
20966 caused (substring ...) to crash on large vectors (Bug#8344).
20967 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20968 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

20972 * editfns.c (general_insert_function): Likewise.
20973 * eval.c (struct backtrace.nargs, interactive_p)
20974 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20975 (funcall_lambda, mark_backtrace): Likewise.
20976 * fns.c (concat): Likewise.
20977 * frame.c (x_set_frame_parameters): Likewise.
20978 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20979 0 if not found, not -1. All callers changed.
20981 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20982 (stack_copy_size): Now size_t, not int.
20983 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20985 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20987 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20988 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20989 All callers changed.
20991 * lisp.h (multibyte_char_to_unibyte):
20992 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20993 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20994 * character.h (CHAR_TO_BYTE8):
20995 * cmds.c (internal_self_insert):
20996 * editfns.c (general_insert_function):
20997 * keymap.c (push_key_description):
20998 * search.c (Freplace_match):
20999 * xdisp.c (message_dolog, set_message_1): All callers changed.
21001 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21003 * keyboard.c (safe_run_hook_funcall): New function.
21004 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21005 don't set the hook to nil, but remove the offending function instead.
21006 (Qcommand_hook_internal): Remove, unused.
21007 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21008 Vcommand_hook_internal.
21010 * eval.c (enum run_hooks_condition): Remove.
21011 (funcall_nil, funcall_not): New functions.
21012 (run_hook_with_args): Call each function through a `funcall' argument.
21013 Remove `cond' argument, now redundant.
21014 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21015 (Frun_hook_with_args_until_failure): Adjust accordingly.
21016 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21018 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21020 * dispextern.h (string_buffer_position): Remove declaration.
21022 * print.c (strout): Remove parameter `multibyte', unused since
21023 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21025 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21026 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21027 All callers changed.
21029 * w32.c (_wsa_errlist): Use braces for struct initializers.
21031 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21032 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21033 All callers changed.
21034 (string_buffer_position): Likewise. Also, make static (it's never
21035 used outside xdisp.c).
21036 (cursor_row_p): Remove parameter `w', unused since
21037 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21039 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21040 All callers changed.
21042 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21044 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21049 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
21050 (ns_update_auto_hide_menu_bar): New functions.
21051 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

21055 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21057 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21059 * nsmenu.m (runDialogAt): Remove argument to timer_check.
21061 2011-03-27 Glenn Morris <rgm@gnu.org>
21063 * syssignal.h: Replace RETSIGTYPE with void.
21064 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
21065 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
21066 Replace SIGTYPE with void everywhere.
21067 * s/usg5-4-common.h (SIGTYPE): Remove definition.

21070 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21072 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21073 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21075 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21077 * w32.c (read_unc_volume): Use parameter `henum', instead of
21078 global variable `wget_enum_handle'.
21080 * keymap.c (describe_vector): Remove parameters `indices' and
21081 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21084 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21086 * keyboard.c (timer_check): Remove parameter `do_it_now',
21087 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
21088 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
21089 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.

21092 * w32menu.c (w32_menu_display_help):
21093 * xmenu.c (show_help_event, menu_help_callback):
21094 Adjust calls to `show_help_echo'.
21096 * gtkutil.c (xg_maybe_add_timer):
21097 * keyboard.c (readable_events):
21098 * process.c (wait_reading_process_output):
21099 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21101 * insdel.c (adjust_markers_gap_motion):
21102 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

21149 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
21151 * w32term.c (x_set_glyph_string_clipping):
21152 Don't pass uninitialized region to CombineRgn.
21154 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
21156 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

21176 2011-03-23 Julien Danjou <julien@danjou.info>
21178 * term.c (Fsuspend_tty, Fresume_tty):
21179 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21180 * window.c (temp_output_buffer_show):
21181 * insdel.c (signal_before_change):
21182 * frame.c (Fhandle_switch_frame):
21183 * fileio.c (Fdo_auto_save):
21184 * emacs.c (Fkill_emacs):
21185 * editfns.c (save_excursion_restore):
21186 * cmds.c (internal_self_insert):
21187 * callint.c (Fcall_interactively):
21188 * buffer.c (Fkill_all_local_variables):
21189 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21191 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21192 unconditionally since it does the check itself.
21194 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21196 Fix more problems found by GCC 4.5.2's static checks.
21198 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21199 the first time through the loop, since we know p0 < p1 then.
21200 This also avoids a gcc -Wstrict-overflow warning.
21202 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21203 leading to a memory leak, possible in functions like
21204 load_charset_map_from_file that can allocate an unbounded number
21205 of objects (Bug#8318).
21207 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21208 that could (at least in theory) be that large.
21210 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21211 This is less likely to overflow, and avoids undefined behavior if
21212 overflow does occur. All callers changed. Use strtoul to scan
21213 for the unsigned long integer.
21214 (pint2hrstr): Simplify and tune code slightly.
21215 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21217 * scroll.c (do_scrolling): Work around GCC bug 48228.
21218 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21220 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21221 This also avoids a warning with gcc -Wstrict-overflow.

21223 This also avoids a warning with gcc -Wstrict-overflow.
21225 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21228 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21230 * process.c (Fmake_network_process): Use socklen_t, not int,
21231 where POSIX says socklen_t is required in portable programs.
21232 This fixes a porting bug on hosts like 64-bit HP-UX, where
21233 socklen_t is wider than int (Bug#8277).
21234 (Fmake_network_process, server_accept_connection):
21235 (wait_reading_process_output, read_process_output):
21238 * process.c: Rename or move locals to avoid shadowing.
21239 (list_processes_1, Fmake_network_process):
21240 (read_process_output_error_handler, exec_sentinel_error_handler):
21241 Rename or move locals.
21242 (Fmake_network_process): Define label "retry_connect" only if needed.
21243 (Fnetwork_interface_info): Fix pointer signedness.
21244 (process_send_signal): Add cast to avoid pointer signedness problem.
21245 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21246 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21248 Make tparam.h and terminfo.c consistent.
21249 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21250 Include tparam.h instead, since it declares them.
21251 * cm.h (PC): Remove extern decl; tparam.h now does this.
21252 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21253 * terminfo.c: Include tparam.h, to check interfaces.
21254 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21255 (tparam): Adjust signature to match interface in tparam.h;
21256 this removes some undefined behavior. Check that outstring and len
21257 are zero, which they always are with Emacs.
21258 * tparam.h (PC, BC, UP): New extern decls.
21260 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21261 (xftfont_open): Rename locals to avoid shadowing.
21263 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21264 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21265 (OTF_TAG_SYM): Omit macro if not needed.
21266 (ftfont_list): Remove unused local.
21267 (get_adstyle_property, ftfont_pattern_entity):
21268 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21269 Rename locals to avoid shadowing.
21271 * xfont.c (xfont_list_family): Mark var as initialized.
21273 * xml.c (make_dom): Now static.
21275 * composite.c (composition_compute_stop_pos): Rename local to
21277 (composition_reseat_it): Remove unused locals.
21278 (find_automatic_composition, composition_adjust_point): Likewise.
21279 (composition_update_it): Mark var as initialized.
21280 (find_automatic_composition): Mark vars as initialized,
21281 with a FIXME (Bug#8290).
21283 character.h: Rename locals to avoid shadowing.
21284 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21285 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21286 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21287 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21288 to avoid shadowing.
21290 * textprop.c (property_change_between_p): Remove; unused.
21292 * intervals.c (interval_start_pos): Now static.
21294 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
21296 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
21297 Rename locals to avoid shadowing.
21299 * sound.c (wav_play, au_play, Fplay_sound_internal):
21300 Fix pointer signedness.
21301 (alsa_choose_format): Remove unused local var.

21310 clobbering (Bug#8298).
21311 * sysdep.c (sys_subshell): Likewise.
21312 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21314 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21315 This should get cleaned up, so that child_setup has the
21316 same signature on all platforms.
21318 * callproc.c (call_process_cleanup): Now static.
21319 (relocate_fd): Rename locals to avoid shadowing.
21321 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

21449 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21450 some of which prompt warnings from gcc -Wbad-function-cast.
21451 (Fformat_time_string, Fencode_time, Finsert_char):

21480 (Fmemory_limit): Cast sbrk's returned value to char *.
21482 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21485 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21487 Use functions, not macros, for up- and down-casing (Bug#8254).
21488 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21489 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21490 to use the following functions instead of these macros.
21491 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21492 EMACS_INT, since callers assume the returned value fits in int.
21493 (upcase1): Likewise, for UPCASE_TABLE.
21494 (uppercasep, lowercasep, upcase): New static inline functions.
21495 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21505 (regex_compile, re_match_2_internal): Mark locals as initialized.
21506 (RETALLOC_IF): Define only if needed.
21507 (WORDCHAR_P): Likewise. This one is never needed, but is used
21508 only in a comment talking about a compiler bug, so put inside
21509 the #if 0 of that comment.
21510 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21511 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21537 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21538 New macros, so that the caller can use some names other than
21539 gcpro1, gcpro2, etc.
21540 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21542 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21543 argument, for consistency with GCPRO2_VAR, etc: it is now the
21544 prefix of the variable, not the variable itself. All uses
21546 * dired.c (directory_files_internal, file_name_completion):
21547 Rename locals to avoid shadowing.
21549 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21550 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21551 dired.c's scmp function, had undefined behavior.
21552 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21553 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21554 * buffer.h: ... to here, because these macros use current_buffer,
21555 and the new implementation with inline functions needs to have
21556 current_buffer in scope now, rather than later when the macros
21558 (downcase, upcase1): New static inline functions.
21559 (DOWNCASE, UPCASE1): Reimplement using these functions.
21560 This avoids undefined behavior in expressions like
21561 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21562 from race conditions in accessing the global variables
21563 case_temp1 and case_temp2.
21564 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21565 * lisp.h (case_temp1, case_temp2): Remove their decls.
21566 * character.h (ASCII_CHAR_P): Move from here ...
21567 * lisp.h: ... to here, so that the inline functions mentioned
21568 above can use them.
21570 * dired.c (directory_files_internal_unwind): Now static.
21572 * fileio.c (file_name_as_directory, directory_file_name):

21575 (file_name_as_directory): Use const pointers when appropriate.
21576 (Fexpand_file_name): Likewise. In particular, newdir might
21577 point at constant storage, so make it a const pointer.
21578 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21579 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21581 (Fset_file_times, Finsert_file_contents, auto_save_error):

21586 to avoid shadowing.
21588 * marker.c (bytepos_to_charpos): Remove; unused.
21590 * lisp.h (verify_bytepos, count_markers): New decls,
21591 so that gcc does not warn that these functions aren't declared.
21593 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21594 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21595 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21596 (copy_text): Remove unused local var.
21598 * filelock.c (within_one_second): Now static.
21599 (lock_file_1): Rename local to avoid shadowing.
21601 * buffer.c (fix_overlays_before): Mark locals as initialized.
21602 (fix_start_end_in_overlays): Likewise. This function should be
21603 simplified by using pointers-to-pointers, but that's a different
21605 (switch_to_buffer_1): Now static.
21606 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21607 (report_overlay_modification): Rename locals to avoid shadowing.
21609 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21610 Fix pointer signedness issue.
21611 (sys_subshell): Mark local as volatile if checking for lint,
21612 to suppress a gcc -Wclobbered warning that does not seem to be right.
21613 (MAXPATHLEN): Define only if needed.
21615 * process.c (serial_open, serial_configure): Move decls from here ...
21616 * systty.h: ... to here, so that they can be checked.
21618 * fns.c (get_random, seed_random): Move extern decls from here ...
21619 * lisp.h: ... to here, so that they can be checked.
21621 * sysdep.c (reset_io): Now static.
21622 (wait_for_termination_signal): Remove; unused.
21624 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
21625 (copy_keymap_item, append_key, push_text_char_description):
21627 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21628 (DENSE_TABLE_SIZE): Remove; unused.
21629 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21630 (describe_map_tree):
21631 Rename locals to avoid shadowing.
21633 * keyboard.c: Declare functions static if they are not used elsewhere.

21655 if GCC considers string literals to be constants.
21657 * lisp.h (fatal_error_signal): Add decl, since it's exported.

21718 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
21719 These macros can no longer be used for assignment.
