3 Avoid file time stamp bug on MS-Windows (Bug#13149).
4 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
5 as FAT32 doesn't update time stamps when truncating them.
6 Also, check that a file time stamp is not a multiple of 100 ns;
7 this should catch all instances of the problem on MS-Windows,
8 as its native file system resolution is 100 ns or worse, and
9 checking for a non-multiple of 100 ns should impose only a small
10 overhead on systems with ns resolution.
12 2013-02-02 Eli Zaretskii <eliz@gnu.org>
14 Avoid encoding file names on MS-Windows when they need to be run
15 through dostounix_filename.
16 * w32.c (normalize_filename): Accept an additional argument
17 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
18 downcase it even if w32-downcase-file-names is non-nil.
19 (dostounix_filename): Accept an additional argument MULTIBYTE and
20 pass it to normalize_filename.
21 (emacs_root_dir): Adjust.
23 * msdos.h (dostounix_filename): Adjust prototype.
25 * w32.h (dostounix_filename): Adjust prototype.
27 * msdos.c (dostounix_filename): Accept an additional argument and
29 (init_environment): Adjust callers of dostounix_filename.
31 * fileio.c (Ffile_name_directory, file_name_as_directory)
32 (directory_file_name, Fexpand_file_name)
33 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
35 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
37 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
38 variables, as egetenv is case-insensitive for DOS_NT.
40 * dired.c (file_name_completion): Don't call Fdirectory_file_name
41 with an encoded file name.
43 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
44 calls to dostounix_filename.
46 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
48 * unexw32.c (unexec): Adjust call to dostounix_filename.
50 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
52 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
55 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
58 * callproc.c (Fcall_process): Make sure program name in PATH and
59 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
60 is passed to exec/spawnve, which fails unless the file-name
63 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
64 even if w32-quote-process-args is nil.
66 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
68 Fix timestamp bug when write-region appends nothing (Bug#13149).
69 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
70 the file's time stamp doesn't change if Emacs happens to write nothing
71 to the file, and on a buggy file system this could cause Emacs to
72 incorrectly infer that the file system doesn't have the bug.
73 Avoid this problem by inhibiting the inference in this case.
75 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
77 * window.h (struct window): Convert base_line_number, base_line_pos
78 and column_number_displayed members from Lisp_Object to ptrdiff_t.
79 Convert region_showing member from Lisp_Object to bitfield.
80 Remove sequence_number member. Adjust comments.
81 * window.c (sequence_number): Remove.
82 (make_window): Initialize column_number_displayed.
83 * print.c (print_object): Follow the printed representation of
84 frames and print window pointer to distinguish between windows.
85 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
86 * xdisp.c (wset_base_line_number, wset_base_line_pos)
87 (wset_column_number_displayed, wset_region_showing): Remove.
88 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
89 (try_scrolling, try_cursor_movement, redisplay_window)
90 (try_window_reusing_current_matrix, try_window_id, display_line)
91 (display_mode_lines, decode_mode_spec): Adjust users.
92 * .gdbinit (pwinx): Do not print sequence_number.
94 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
96 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
97 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
98 * dired.c: Include <fcntl.h>.
99 (open_directory): New function, which uses open and fdopendir
100 rather than opendir. DOS_NT platforms still use opendir, though.
101 (directory_files_internal, file_name_completion): Use it.
102 (file_attributes): New function, with most of the old Ffile_attributes.
103 (directory_files_internal, Ffile_attributes): Use it.
104 (file_attributes, file_name_completion_stat): First arg is now fd,
105 not dir name. All uses changed. Use fstatat rather than lstat +
107 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
108 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
109 (emacs_readlinkat): New function, with much of the old
110 Ffile_symlink_p, but with an fd argument for speed.
111 It uses readlinkat rather than careadlinkatcwd, so that it
112 need not assume the working directory.
113 (Ffile_symlink_p): Use it.
114 * filelock.c (current_lock_owner): Use emacs_readlinkat
115 rather than emacs_readlink.
116 * lisp.h (emacs_readlinkat): New decl.
117 (READLINK_BUFSIZE, emacs_readlink): Remove.
118 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
119 (emacs_norealloc_allocator, emacs_readlink): Remove.
120 This stuff is moved to fileio.c.
121 * w32.c (fstatat, readlinkat): New functions.
122 (careadlinkat): Don't check that fd == AT_FDCWD.
123 (careadlinkatcwd): Remove; no longer needed.
125 2013-01-31 Glenn Morris <rgm@gnu.org>
127 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
128 (Fwrite_region): Update for new choose_write_coding_system args.
129 Move the last piece of choose_write_coding_system here. (Bug#13522)
130 (syms_of_fileio): Add choose-write-coding-system.
132 2013-01-30 Eli Zaretskii <eliz@gnu.org>
134 * w32.c (sys_open): Zero out the flags for the new file descriptor.
135 (sys_close): Zero out the flags for the file descriptor before
136 closing it. (Bug#13546)
138 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
139 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
140 CharNextExA and CharPrevExA to iterate over file names encoded in
143 * w32.c (w32_get_long_filename, init_environment, readlink):
144 Support file names encoded in DBCS codepages.
145 (readlink): Use the current file-name-coding-system, not the ANSI
146 codepage, to decode and handle targets of symlinks.
148 2013-01-28 Eli Zaretskii <eliz@gnu.org>
150 * w32.c (opendir): Now accepts a 'const char *'.
152 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
154 Remove obsolete redisplay code. See the discussion at
155 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
156 * dispnew.c (preemption_period, preemption_next_check): Remove.
157 (Vredisplay_preemption_period): Likewise.
158 (update_frame, update_single_window, update_window, update_frame_1):
159 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
160 used, following the 2012-06-22 change.
162 2013-01-25 Eli Zaretskii <eliz@gnu.org>
164 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
166 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
168 * font.c (num_fonts): Remove the leftover from old
169 debugging code. Adjust comment style here and there.
170 * insdel.c (insert_1): Remove.
171 * lisp.h (insert_1): Remove prototype.
172 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
174 2013-01-25 Eli Zaretskii <eliz@gnu.org>
176 * w32.c (max_filename_mbslen): New function.
177 (normalize_filename, readdir): Use it to detect locales where ANSI
178 encoding of file names uses a double-byte character set (DBCS).
179 If a DBCS encoding is used, advance by characters using
180 CharNextExA, instead of incrementing a 'char *' pointer. Use
181 _mbslwr instead of _strlwr. (Bug#13515)
183 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
184 request of memory reservation to 1.7GB. (Bug#13065)
186 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
188 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
189 at check_extra_latin label. (Bug#13505)
191 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
193 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
194 Avoid redundant calls to strlen.
196 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
198 Drop async_visible and async_iconified fields of struct frame.
199 This is possible because async input is gone; for details, see
200 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
201 * frame.h (struct frame): Remove async_visible and async_iconified
202 members, convert garbaged to unsigned bitfield. Adjust comments.
203 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
204 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
205 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
206 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
207 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
209 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
210 properly. Likewise for obscured.
212 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
215 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
217 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
219 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
220 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
222 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
224 * xdisp.c (message2, message2_nolog): Remove functions.
225 (message3, message3_nolog): Extract nbytes and multibyteness directly
226 from the string. Change all callers.
227 (message3_nolog): Don't set message_enable_multibyte since set_message
228 will reset it anyway.
229 (message1, message1_nolog): Use message3.
230 (vmessage): Use a stack allocated buffer rather than f->message_buf.
231 (with_echo_area_buffer): Remove last two arguments. Update all callers.
232 (set_message): Drop all but the second arg, which has to be a string.
233 (set_message_1): Simplify now that we know that a1 is NULL and the
234 second arg is a string.
235 * frame.h (struct frame): Remove `message_buf' field.
236 Use glyphs_initialized_p instead.
237 (FRAME_MESSAGE_BUF): Remove macro.
238 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
239 * lisp.h (message2, message2_nolog): Remove declarations.
240 (message3, message3_nolog): Update declarations.
241 * keyboard.c (read_char_minibuf_menu_text)
242 (read_char_minibuf_menu_width): Remove vars.
243 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
244 to correctly handle multibyte strings.
245 * frame.c (delete_frame): Don't free message_buf any more.
246 * editfns.c (message_text, message_length): Remove vars.
247 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
248 * fileio.c (auto_save_error): Use message3 instead of message2.
249 * dispnew.c (adjust_frame_message_buffer): Remove function.
251 2013-01-23 Eli Zaretskii <eliz@gnu.org>
253 * w32term.c (w32fullscreen_hook): Account correctly for the screen
254 real estate used for the tool bar and the menu bar.
256 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
258 * insdel.c (prepare_to_modify_buffer): Force redisplay if
259 hidden buffer is prepared to modification (Bug#13164).
261 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
263 * window.h (struct window): Change window_end_valid member from
264 Lisp_Object to a bitfield. Adjust comments.
265 (wset_window_end_valid): Remove.
266 * window.c (adjust_window_count): Clear window_end_valid.
267 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
268 (Fwindow_line_height, set_window_buffer, Frecenter)
269 (Fsplit_window_internal, Fdelete_other_windows_internal)
270 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
271 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
272 * xdisp.c (check_window_end, reconsider_clip_changes)
273 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
274 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
275 (find_first_unchanged_at_end_row, try_window_id): Likewise.
277 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
279 * xdisp.c (mark_window_display_accurate): Simplify the loop
280 assuming that the only one of vchild, hchild or buffer window
281 slots is non-nil. Call mark_window_display_accurate_1 for
282 the leaf windows only.
283 (mark_window_display_accurate_1): Always assume leaf window.
286 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
288 * emacs.c (Qkill_emacs_hook): Now static.
290 * fileio.c (Finsert_file_contents): Simplify.
291 Remove unnecessary assignments and tests.
293 2013-01-21 Eli Zaretskii <eliz@gnu.org>
295 * w32.c (acl_set_file): Don't test for errors unless
296 set_file_security returns FALSE. Avoids spurious errors when
299 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
301 * fileio.c (Finsert_file_contents): Revert code introduced at
302 2013-01-18 in favor of the simpler and generally better fix.
303 Save stack space by removing 'buffer' and reusing 'read_buf'
306 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
308 * lisp.h (eabs): Define unconditionally (Bug#13419).
309 The old "#if !defined (eabs)" was an unnecessary revenant of back
310 when this macro was called "abs". Document 'eabs' better.
312 2013-01-19 Glenn Morris <rgm@gnu.org>
314 * fns.c (Frandom): Doc fix.
316 2013-01-19 Eli Zaretskii <eliz@gnu.org>
318 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
319 segfault when there are lots of overlays.
321 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
322 when there are lots of overlays. See
323 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
324 for the details and a way to reproduce.
326 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
328 * fileio.c: Use O_APPEND to append.
329 This corresponds better to the natural interpretation of "append",
330 and avoids the need to open the output file twice, or to invoke
331 lseek when APPEND is neither nil nor a number.
332 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
333 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
334 file possibly twice, and lseeking to its end; this avoids the
335 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
336 at the same time: the combination is never needed and apparently
337 it doesn't work with DOS_NT.
339 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
340 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
342 Allow floating-point file offsets.
343 Problem reported by Vitalie Spinu in
344 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
345 * fileio.c (emacs_lseek): Remove.
346 (file_offset): New function.
347 (Finsert_file_contents, Fwrite_region): Use it.
349 2013-01-19 Chong Yidong <cyd@gnu.org>
351 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
352 aborting on Fsignal (Bug#13289).
354 2013-01-19 Eli Zaretskii <eliz@gnu.org>
356 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
357 set_file_security as failure due to insufficient privileges.
358 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
359 (fstat): Return owner and group like 'stat' and 'lstat' do.
361 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
363 Work around bug in CIFS and vboxsf file systems (Bug#13149).
364 The bug was observed on Ubuntu operating inside a virtual machine,
365 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
366 The workaround introduces a race condition on non-buggy hosts,
367 but it's an unlikely race and anyway there's a nearly identical
368 nearby race that can't be fixed.
369 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
371 (Fwrite_region): Test for file system time stamp bug.
372 (init_fileio): New function.
373 * lisp.h (init_fileio): Declare it.
374 * emacs.c (main): Call it.
376 * fileio.c (Finsert_file_contents): Simplify new diagnostic
377 and make it more consistent with other stat-failure diagnostics.
379 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
381 Fix crash when inserting data from non-regular files. See
382 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
383 for the error description produced by valgrind.
384 * fileio.c (read_non_regular): Rename to read_contents.
385 Free Lisp_Save_Value object used to pass parameters.
386 (read_non_regular_quit): Rename to read_contents_quit.
387 (Finsert_file_contents): Redesign internal file reading loop to adjust
388 gap and end positions after each read and so help make_gap to work
389 properly. Do not signal an I/O error too early and so do not leave
390 not yet decoded characters in a buffer, which was the reason of
391 redisplay crash. Use list2 to build return value. Adjust comments.
393 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
395 Close a race when statting and reading files (Bug#13149).
396 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
397 This avoids a race if the file is renamed between stat and open.
398 This race is not the problem originally noted in Bug#13149;
399 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
401 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
403 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
404 objects, related functions and macros.
405 (make_save_value): Adjust prototype.
406 (make_save_pointer): New prototype.
407 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
408 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
409 * alloc.c (format_save_value): Rename to make_save_value.
410 (make_save_pointer): New function.
411 (record_xmalloc): Use make_save_pointer.
412 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
413 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
414 Change users of make_save_value to make_save_pointer.
415 Likewise for format_save_value and make_save_value.
417 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
419 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
420 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
421 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
424 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
426 * alloc.c (free_save_value): Now static.
428 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
430 * keymap.c (map_keymap_internal): Use format_save_value.
431 (map_keymap_char_table_item): Adjust accordingly.
432 * fileio.c (non_regular_fd, non_regular_inserted)
433 (non_regular_nbytes): Remove.
434 (Finsert_file_contents): Convert trytry to ptrdiff_t. Use
435 format_save_value to pass parameters to read_non_regular.
436 (read_non_regular): Use XSAVE_ macros to extract parameters.
438 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
440 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
442 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
444 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
445 extraction from any Lisp_Save_Value slot. Add type checking.
446 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
447 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
448 * xselect.c: All users changed.
450 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
452 Some convenient bits to deal with Lisp_Save_Values.
453 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
454 (allocate_misc): Remove prototype.
455 (format_save_value): New prototype.
456 * alloc.c (allocate_misc): Revert back to static.
457 (format_save_value): New function to build Lisp_Save_Value
458 object with the specified internal structure.
459 (make_save_value): Reimplement using format_save_value.
460 * editfns.c (save_excursion_save): Use format_save_value.
461 (save_excursion_restore): Use XSAVE_OBJECT.
463 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
465 Avoid needless casts with XSAVE_POINTER.
466 * alloc.c (mark_object) [GC_MARK_STACK]:
467 * dired.c (directory_files_internal_unwind):
468 * fileio.c (do_auto_save_unwind):
469 * gtkutil.c (pop_down_dialog):
470 * keymap.c (map_keymap_char_table_item):

497 (mark_object): Likewise.
498 * editfns.c (save_excursion_save): Pack everything within
499 Lisp_Save_Value and so avoid xmalloc.
500 (save_excursion_restore): Adjust to match new layout. Use free_misc
501 because we do not allocate extra memory any more. Add eassert.
502 * print.c (print_object): New code to print Lisp_Save_Value. Do not
503 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

584 emacsclient -t should not suspend Emacs server (Bug#13387)
585 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
587 * term.c (init_tty): Use them instead of rolling our own code.
588 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
589 switches from 'signal' to 'pthread_sigmask', which is safer in
590 multithreaded applications.
591 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
592 which has already arranged for that.
593 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

604 the type of per-buffer values where appropriate.
605 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
606 predicate, which is how it's really used now. Adjust comment.

608 * buffer.c (buffer_slot_type_mismatch): Remove.
609 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

613 left-margin-width, right-margin-width, left-fringe-width,
614 right-fringe-width, scroll-bar-width and buffer-display-count.
615 Use Qstringp for default-directory, buffer-file-name,
616 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
617 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
619 * data.c (store_symval_forwarding): Adjust to call the predicate.
621 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

643 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case

662 trailing dash is properly added.
664 2013-01-05 Eli Zaretskii <eliz@gnu.org>
666 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
667 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
668 digits for buffer positions, before misalignment starts.
669 Display "0" for integer "object" field.
670 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
671 Display the newline glyph more unambiguously.
673 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
675 * nsterm.m (ns_draw_underwave):
676 * w32term.c (w32_draw_underwave):
677 * xterm.c (x_draw_underwave): Make underwave look more triangular
678 and also degrade gracefully for small fonts. (Bug#13000)
680 * nsterm.m (ns_draw_text_decoration):
681 * w32term.c (x_draw_glyph_string):
682 * xterm.c (x_draw_glyph_string): Don't use previous underline
683 thickness and position if previous underline type is underwave.

703 * term.c (tty_ins_del_lines):
704 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
705 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
707 2012-12-31 Eli Zaretskii <eliz@gnu.org>
709 * w32.c (unsetenv): Set up the string passed to _putenv
711 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
712 for the bug this caused.
714 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
716 * coding.c (Qmac): Now static.
718 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
720 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
721 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
722 handlebox_widget. Set toolbar_in_hbox to false/true, set
723 toolbar_is_packed to true.
724 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
725 (update_frame_tool_bar): Check toolbar_is_packed for packing.
726 Show all on TOOLBAR_TOP_WIDGET.
727 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned

729 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
730 Check toolbar_is_packed.
731 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
732 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
733 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
735 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
736 (xg_update_menubar): Update title only if
737 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
738 (xg_update_submenu): Skip tearoff only if
739 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
740 (xg_initialize): Initialize xg_detached_menus only if
741 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
743 * xterm.h (struct x_output): Surround handlebox_widget with
744 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
745 toolbar_in_hbox is bool.
747 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
749 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
750 (LIBS_GNUSTEP): Define.
751 (LIBES): Add $(LIBS_GNUSTEP).
752 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
754 2012-12-30 Eli Zaretskii <eliz@gnu.org>
756 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
757 continuation glyph on a TTY with an indication of an empty line.
760 2012-12-29 Eli Zaretskii <eliz@gnu.org>
762 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
763 file's SELinux context or ACLs successfully set, nil otherwise.
765 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
767 * w32proc.c (reader_thread): Avoid passing NULL handles to
768 SetEvent and WaitForSingleObject.
770 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
772 Port EXTERNALLY_VISIBLE to Clang 3.2.
773 * conf_post.h (__has_attribute): New macro.
774 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
776 2012-12-27 Glenn Morris <rgm@gnu.org>
778 * cygw32.c (Fcygwin_convert_file_name_to_windows)
779 (Fcygwin_convert_file_name_from_windows): Doc fixes.
781 2012-12-27 Eli Zaretskii <eliz@gnu.org>
783 * fileio.c (file_name_as_directory, directory_file_name):
784 Accept an additional argument MULTIBYTE to indicate whether the input C
785 came from a multibyte or a unibyte Lisp string; all callers
786 adjusted. Don't assume the input string is always multibyte.
788 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
789 don't ENCODE_FILE them, and return a unibyte string if the input
791 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
792 don't assume the input strings will always be multibyte. If the
793 input strings are multibyte, decode strings obtained from C
796 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
798 * lisp.h (toplevel): Add two notices to the comment about
799 defining a new Lisp data type.
800 * print.c (print_object): If Lisp_Save_Value object's pointer
801 is the address of a memory area containing Lisp_Objects, try
803 * alloc.c (valid_lisp_object_p): Adjust comment.
805 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
807 * keyboard.c (record_asynch_buffer_change): Initialize an event
808 only if it's really needed.
809 * frame.h (enum output_method): Remove output_mac member since
810 it's a leftover from the deleted code.
811 * frame.c (Fframep): Adjust user here ...
812 * terminal.c (Fterminal_live_p): ... and here.
813 * coding.c (Qmac): Now here because it's only used to denote
814 end-of-line encoding type.
815 (syms_of_coding): DEFSYM it.
816 * frame.h (Qmac): Remove duplicated declaration.
818 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
820 * window.c (select_window_1): Now static, since it's used only here.
822 2012-12-25 Eli Zaretskii <eliz@gnu.org>
824 * window.c (window_body_cols): Subtract display margins from the
825 window body width on TTYs as well. See
826 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
827 for the original report.
829 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
831 * xdisp.c (redisplay_window): Remove inner local variable
832 because the outer shadowed one has the same meaning.
833 * xterm.h (struct x_output): Remove toolbar_detached member since it's
835 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
836 (xg_create_tool_bar): Adjust users.
838 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
840 * buffer.h (BUF_COMPACT): New macro to follow the common style.
841 * buffer.c (Fget_buffer_create): Use it to set compact field of
842 struct buffer_text to avoid accessing an uninitialized value
843 when compact_buffer is called for the first time.
844 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
845 (Fset_buffer_modified_p): Use buffer_window_count to check
846 whether the buffer is displayed in some window.
847 * xdisp.c (message_dolog): Likewise.
849 2012-12-23 Eli Zaretskii <eliz@gnu.org>
851 * w32.c (acl_set_file): If setting the file security descriptor
852 fails, and the new DACL is identical to the existing one, silently
853 return success. This fixes problems for users backing up their
854 own files without having the necessary privileges for setting
855 security descriptors.
857 * w32proc.c (reader_thread): Do not index fd_info[] with negative
859 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
860 after WaitForSingleObject returns normally. This expedites reader
861 thread shutdown when delete_child triggers it.
862 (reap_subprocess): More accurate commentary for why we call
863 delete_child only when cp->fd is negative.
865 * w32.c (sys_close): Do not call delete_child on a subprocess
866 whose handle is not yet closed. Instead, set its file descriptor
867 to a negative value, so that reap_subprocess will call
868 delete_child on that subprocess when its SIGCHLD arrives.
869 This avoids closing handles used for communications between sys_select
870 and reader_thread, which doesn't give sys_select a chance to
871 notice that the process exited and invoke the SIGCHLD handler for
874 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
876 * nsfns.m (Fns_do_applescript): Run event loop until script has
877 been executed (Bug#12969).
878 (ns_run_ascript): Chech as_script for nil, set to nil after
881 2012-12-22 Martin Rudalics <rudalics@gmx.at>

887 * w32term.c (w32fullscreen_hook): New function.
888 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
890 2012-12-21 Eli Zaretskii <eliz@gnu.org>
892 * fileio.c (Finsert_file_contents): Doc fix.
894 * w32proc.c (new_child, delete_child, find_child_pid): For a
895 subprocess, consider its slot being in use as long as its process
896 handle (procinfo.hProcess) is not NULL. This avoids reusing the
897 slot when a new process is started immediately after killing
898 another one, without waiting enough time for the first process to
899 be reaped and resources allocated for it be orderly freed.
901 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
903 2012-12-21 Chong Yidong <cyd@gnu.org>
905 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
907 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
909 2012-12-21 Eli Zaretskii <eliz@gnu.org>
911 * w32.c (get_name_and_id): Always pass NULL as the first argument
912 of lookup_account_sid. Avoids crashes with UNC file names that
913 refer to DFS domains, not to specific machine names. (Bug#12621)
914 Remove now unused argument FNAME; all callers changed.
915 (get_file_owner_and_group): Remove now unused argument FNAME; all
918 2012-12-21 Chong Yidong <cyd@gnu.org>
920 * editfns.c (Finsert_char): Since read-char-by-name now signals an
921 error for invalid chars, don't check for a nil return value.
923 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
925 Avoid calls to CHAR_TO_BYTE if byte position is known.
926 * editfns.c (make_buffer_string_both): Use move_gap_both.
927 (Fbuffer_string): Use make_buffer_string_both.
928 * marker.c (buf_charpos_to_bytepos): Convert to eassert.

932 * fileio.c (Finsert_file_contents): Use move_gap_both.
933 * search.c (Freplace_match): Likewise.
934 * process.c (process_send_region): Likewise. Use convenient
935 names for byte positions.
936 * lisp.h (charpos_to_bytepos): Remove prototype.
937 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
938 * insdel.c (move_gap): Likewise.

947 (redisplay_internal): Don't bother selecting the frame to get the
948 proper value of frame-local variables (bug#13225).
950 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
952 * textprop.c (set_text_properties_1): Do not allow NULL interval.
953 Rename 4th argument since it may be buffer or string. Adjust comment.
954 * intervals.c (graft_intervals_info_buffer): Find an interval here.
956 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
958 * coding.c (Fdetect_coding_region): Do not check start and end with
959 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
960 (code_convert_region): Likewise.
962 2012-12-18 Eli Zaretskii <eliz@gnu.org>
964 * w32.c (acl_get_file, acl_set_file): Run the file name through

1011 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1012 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1013 for some of that bug's symptoms can now cause Emacs to abort.
1014 Remove the workaround.
1015 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1016 The bug that caused SIGCHLD to get lost has been fixed, and the
1017 workaround for it can now cause Emacs to abort.
1019 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1021 * sysdep.c (emacs_abort): Bump backtrace size to 40.

1029 and copy ACL entries of file in addition to SELinux context if set.
1030 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1032 * Makefile.in (LIBACL_LIBS): New macro.

1047 * w32proc.c (new_child): Initialize input_file and
1048 pending_deletion members of the child.

1061 * callproc.c (Fcall_process): Don't overwrite infile with result
1063 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1064 asynchronous subprocess, record the name of the input file name,
1066 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1067 delete the file, record it as pending deletion when the subprocess

1095 'lstat', which don't need that information, much faster.
1097 * dired.c (Ffile_attributes) [WINDOWSNT]:
1098 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1099 owner and group information from 'lstat'.
1101 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1103 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1104 as that confuses set-auto-coding, so insist on the head-read

1133 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1135 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1136 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1137 Remove unnecessary S_ISLNK test, as (contra the comments) this
1138 function can't copy symlinks. Improve quality of error message
1139 when attempting to copy files that are neither regular files nor

1158 * inotify.c (inotify_callback): Generate an Emacs event for every
1159 incoming inotify event.

1441 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1443 * frame.c (make_frame): Do not set window's buffer to t.
1444 * window.c (Fsplit_window_internal): Likewise. Previously it was
1445 used to indicate that the window is being set up. Now we use
1446 set_window_buffer for all new windows, so the condition in ...
1447 (Fset_window_buffer): ... is always true and can be removed.
1449 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1451 Convenient macro to check whether the buffer is hidden.
1452 * buffer.h (BUFFER_HIDDEN_P): New macro.
1453 * frame.c (make_frame): Use it. Adjust comment.
1454 * buffer.c (candidate_buffer): New function.
1455 (Fother_buffer, other_buffer_safely): Use it.
1457 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1459 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1460 if the child process is still running. Instead, exit the wait
1461 loop and return zero. (Bug#13086)
1463 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1465 * frame.h (x_char_width, x_char_height): Remove prototypes.
1466 * w32term.h (x_char_width, x_char_height): Likewise.
1467 * xfns.c (x_char_width, x_char_height): Remove.

1470 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
1472 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
1473 * keyboard.c (command_loop_1): Remove prototype.
1474 (command_loop_2, top_level_1): Add static to match prototype.
1476 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1478 Fix a recently-introduced delete-process race condition.
1479 * callproc.c, process.h (record_kill_process):
1480 New function, containing part of the old call_process_kill.
1481 (call_process_kill): Use it.
1482 This does not change call_process_kill's behavior.
1483 * process.c (Fdelete_process): Use record_kill_process to fix a
1484 race condition that could cause Emacs to lose track of a child.
1486 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1488 Avoid code duplication between prev_frame and next_frame.
1489 * frame.c (candidate_frame): New function. Add comment.
1490 (prev_frame, next_frame): Use it. Adjust comment.
1492 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1494 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1495 fails, signal an error instead of continuing with an empty
1497 Encode expanded temp file pattern before passing it to mkstemp or
1500 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1501 Encode the file name before passing it to dostounix_filename, in
1502 case it will downcase it (under w32-downcase-file-names).
1505 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1507 Minor call-process cleanups.
1508 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1509 at the same time as other platforms, to simplify analysis.
1510 No need for fd0_volatile since we have synch_process_fd.
1511 Avoid needless emacs_close; arg is always negative.
1513 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1515 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1518 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1520 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1521 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1522 and mouse_face_hidden members to a bitfields.
1523 * frame.h (struct frame): Remove set-but-not-used space_width member.
1524 (FRAME_SPACE_WIDTH): Remove.
1525 * nsterm.m, w32term.c, xterm.c: Adjust users.
1526 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1527 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1528 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1529 members to a bitfields.
1531 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1533 Don't let call-process be a zombie factory (Bug#12980).
1534 Fixing this bug required some cleanup of the signal-handling code.
1535 As a side effect, this change also fixes a longstanding rare race
1536 condition whereby Emacs could mistakenly kill unrelated processes,
1537 and it fixes a bug where a second C-g does not kill a recalcitrant
1538 synchronous process in GNU/Linux and similar platforms.
1539 The patch should also fix the last vestiges of Bug#9488,
1540 a bug which has mostly been fixed on the trunk by other changes.
1541 * callproc.c, process.h (synch_process_alive, synch_process_death)
1542 (synch_process_termsig, sync_process_retcode):
1543 Remove. All uses removed, to simplify analysis and so that
1544 less consing is done inside critical sections.
1545 * callproc.c (call_process_exited): Remove. All uses replaced
1546 with !synch_process_pid.
1547 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1548 These take the role of what used to be in unwind-protect arg.
1550 (block_child_signal, unblock_child_signal):
1551 New functions, to avoid races that could kill innocent-victim processes.
1552 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1553 (call_process_kill): Record killed processes as deleted, so that
1554 zombies do not clutter up the system. Do this inside a critical
1555 section, to avoid a race that would allow the clutter.
1556 (call_process_cleanup): Fix code so that the second C-g works again
1557 on common platforms such as GNU/Linux.
1558 (Fcall_process): Create the child process in a critical section,
1559 to fix a race condition. If creating an asynchronous process,
1560 record it as deleted so that zombies do not clutter up the system.
1561 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1562 light of these changes. Omit unnecessary call to emacs_close
1563 before failure, as the unwind-protect code does that.
1564 * callproc.c (call_process_cleanup):
1565 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1566 * process.c (record_deleted_pid): New function, containing
1567 code refactored out of Fdelete_process.
1568 (Fdelete_process): Use it.
1569 (process_status_retrieved): Remove. All callers changed to use
1570 child_status_change.
1571 (record_child_status_change): Remove, folding its contents into ...
1572 (handle_child_signal): ... this signal handler. Now, this
1573 function is purely a handler for SIGCHLD, and is not called after
1574 a synchronous waitpid returns; the synchronous code is moved to
1575 wait_for_termination. There is no need to worry about reaping
1576 more than one child now.
1577 * sysdep.c (get_child_status, child_status_changed): New functions.
1578 (wait_for_termination): Now takes int * status and bool
1579 interruptible arguments, too. Do not record child status change;
1580 that's now the caller's responsibility. All callers changed.
1581 Reimplement in terms of get_child_status.
1582 (wait_for_termination_1, interruptible_wait_for_termination):
1583 Remove. All callers changed to use wait_for_termination.
1584 * syswait.h: Include <stdbool.h>, for bool.
1585 (record_child_status_change, interruptible_wait_for_termination):
1587 (record_deleted_pid, child_status_changed): New decls.
1588 (wait_for_termination): Adjust to API changes noted above.
1590 * bytecode.c, lisp.h (Qbytecode): Remove.
1591 No longer needed after 2012-11-20 interactive-p changes.
1593 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1595 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1596 the scroll margin, move point outside the margin. (Bug#13055)
1598 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1600 * gtkutil.c (my_log_handler): New function.
1601 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1603 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1605 * lisp.h (modify_region): Rename to...
1606 (modify_region_1): ...new prototype.
1607 * textprop.c (modify_region): Now static. Adjust users.
1608 * insdel.c (modify_region): Rename to...
1609 (modify_region_1): ...new function to work with current buffer.
1610 Adjust comment and users. Use true and false for booleans.
1612 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1614 * alloc.c (free_save_value): New function.
1615 (safe_alloca_unwind): Use it.
1616 * lisp.h (free_save_value): New prototype.
1617 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1619 (save_excursion_restore): Adjust to match saved data structure.
1620 Use free_save_value to offload some work from GC. Drop obsolete
1623 2012-12-03 Chong Yidong <cyd@gnu.org>
1625 * fileio.c (Vauto_save_list_file_name): Doc fix.
1627 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1629 * w32fns.c: Remove prototype of atof.
1630 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1632 (file_dialog_callback): Make it UINT_PTR.
1634 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1637 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1638 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1641 2012-12-03 Glenn Morris <rgm@gnu.org>
1643 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1645 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1647 Fix xpalloc confusion after memory is exhausted.
1648 * alloc.c (xpalloc): Comment fix.
1649 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1650 and signals an error, do not clear charset_table_size, as
1651 charset_table is still valid.
1652 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1654 Use execve to avoid need to munge environ (Bug#13054).
1655 * callproc.c (Fcall_process):
1656 * process.c (create_process):
1657 Don't save and restore environ; no longer needed.
1658 * callproc.c (child_setup):
1659 Use execve, not execvp, to preserve environ.
1661 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1663 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1665 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1667 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1668 display for sliced images (Bug#10500).
1670 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1672 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1674 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1675 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1677 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1679 * xdisp.c (window_outdated): Remove eassert since it hits
1680 some suspicious corner cases (see Bug#13007 and Bug#13012).
1681 (mode_line_update_needed): New function.
1682 (redisplay_internal, redisplay_window): Use it.
1683 (ensure_selected_frame): New function.
1684 (redisplay_internal, unwind_redisplay): Use it.
1685 (redisplay_internal): Move comment about buffer_shared...
1686 (buffer_shared_and_changed): ...near to its real use.
1688 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1690 * callproc.c (Fcall_process): Don't misreport vfork failure.
1692 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1694 * callproc.c (Fcall_process): Fix vfork portability problems.
1695 Do not assume that fd[0], count, filefd, and save_environ survive
1696 vfork. Fix bug whereby wrong errno value could be reported for
1697 pipe failure. Some minor cleanups, too, as follows. Move buf and
1698 bufsize to the context where they're needed. Change new_argv to
1699 be of type char **, as this is more convenient and avoids casts.
1700 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1701 Now local constants, not macros.
1703 2012-11-18 Kenichi Handa <handa@gnu.org>
1705 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1706 for the variable "f".
1708 2012-11-13 Kenichi Handa <handa@gnu.org>
1710 * font.c (font_unparse_xlfd): Exclude special characters from the
1711 generating XLFD name.
1713 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1715 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1717 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1719 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1726 * lread.c (readbyte_from_file): Assume EINTR is defined.
1727 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1728 Assume EIO and EAGAIN are defined.
1729 * unexcoff.c (write_segment): Assume EFAULT is defined.
1731 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1733 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1736 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1737 highlighting on the frame was cleared. Prevents assertion
1738 violations when repeatedly clicking on the "Top" link of the
1739 "bread-crumbs" in Info buffers.
1741 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

1748 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1749 were always defined.
1751 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1753 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1754 between bpos_covered and bpos_max. This fixes cursor display when
1755 several display strings follow each other.
1757 * .gdbinit (pgx): If the glyph's object is a string, display the
1758 pointer to string data, rather than the value of the string object
1759 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1761 * indent.c (Fvertical_motion): If the starting position is covered
1762 by a display string, return to one position before that, to avoid
1763 overshooting it inside move_it_to. (Bug#12930)
1765 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

1775 asked_for_visible and menubar_active members.
1776 Drop unused pending_menu_activation member.
1777 * xterm.h (struct x_output): Drop outdated #if 0 code.
1778 Use bitfields for explicit_parent, asked_for_visible,
1779 has_been_visible and net_wm_state_hidden_seen members.

1783 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1784 of a literal "/". (Bug#12955)
1785 (gl-stamp): Invoke fc.exe directly, not through cmd.
1787 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1789 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1790 * dired.c: Assume HAVE_DIRENT_H.
1791 (NAMLEN): Remove, replacing with ...
1792 (dirent_namelen): New function. All uses changed. Use the GNU macro
1793 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1794 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1795 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1796 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1798 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1799 * ndir.h: Rename to ../nt/inc/dirent.h.
1800 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1801 Do not include <dirent.h>; no longer needed.
1802 * w32.c: Include <dirent.h> rather than "ndir.h".
1804 2012-11-23 Chong Yidong <cyd@gnu.org>
1806 * xftfont.c (xftfont_open): Remove duplicate assignment.
1808 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1810 * alloc.c (Fgarbage_collect): Unblock input after clearing
1811 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1812 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1813 * msdos.c (IT_frame_up_to_date): Use it here...
1814 * w32term.c (w32_frame_up_to_date): ...here...
1815 * xterm.c (XTframe_up_to_date): ...and here...
1816 * nsterm.m (ns_frame_up_to_date): ...but not here.
1817 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1819 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1820 Do not check whether GC is in progress.
1822 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1824 * xdisp.c (window_buffer_changed): New function.
1825 (update_menu_bar, update_tool_bar): Use it to
1826 simplify large 'if' statements.
1827 (redisplay_internal): Generalize commonly used
1828 'tail' and 'frame' local variables.
1830 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1832 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1833 with Windows system header.
1835 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1837 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1838 * alloc.c: Assume unistd.h exists.
1839 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.

1842 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1843 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1844 * w32.h (getcwd): Remove decl.
1846 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

1849 Make it set selected_window as well.
1850 (update_tool_bar): Use it.

1854 * emacs.c (main): Set the G_SLICE environment variable for all
1855 Cygwin builds, not just GTK builds. See
1856 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1858 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1860 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1861 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1862 Define for the MSVC compiler.
1864 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1866 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1867 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1868 dostounix_filename. Prevents crashes down the road, because
1869 dostounix_filename assumes it gets a unibyte string.
1870 Reported by Michel de Ruiter <michel@sentient.nl>, see

1883 (Fsymbol_function): Never signal an error.
1884 (Finteractive_form): Ignore Qunbound.
1886 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>

1895 decide whether all windows or frames should be updated.
1896 (window_outdated): New function.
1897 (text_outside_line_unchanged_p, redisplay_window): Use it.
1898 (redisplay_internal): Likewise. Fix indentation.
1900 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1902 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1903 (syms_of_eval): Remove corresponding defsubr.
1904 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1906 2012-11-19 Daniel Colascione <dancol@dancol.org>
1908 * w32fns.c (Fx_file_dialog):
1909 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1910 cygwin_convert_file_name*.
1912 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1913 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1915 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1917 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1919 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1921 * w32select.c: Include w32common.h before w32term.h, so that
1922 windows.h gets included before w32term.h uses some of its
1923 features, see below.
1925 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1927 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1929 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1931 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1933 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1934 (ns_select): Return at once if events are held (Bug#12834).
1936 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1938 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1939 Needed following 2012-10-20 change. (Bug#12902)
1941 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1943 * w32proc.c (waitpid): Remove unused label get_result.
1945 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1947 * makefile.w32-in (SYSWAIT_H): New macro.
1948 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1949 ($(BLD)/sysdep.$(O)): Update dependencies.
1951 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1953 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1954 * callproc.c (relocate_fd): Assume F_DUPFD.
1955 * emacs.c, term.c (O_RDWR): Remove.
1956 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1957 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1958 * nsterm.m: Assume <fcntl.h> exists.
1959 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1960 (create_pty, Fmake_network_process, server_accept_connection)
1961 (wait_reading_process_output, init_process_emacs):
1963 (wait_reading_process_output): Put in a special case for WINDOWSNT
1964 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1965 It's not clear this is needed, but it's a more-conservative change.
1966 (create_process): Assume FD_CLOEXEC.
1967 (create_process, create_pty): Assume O_NOCTTY.
1968 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1969 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1970 Omit if not DOS_NT, since F_GETFL is not defined there.
1971 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1972 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1974 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1975 lack it, since gnulib guarantees this.
1976 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1978 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1980 * w32.c (faccessat): Pretend that directories have the execute bit
1981 set. Emacs expects that, e.g., in files.el:cd-absolute.
1983 * w32proc.c (create_child): Don't clip the PID of the child
1984 process to fit into an Emacs integer, as this is no longer a
1986 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1987 reaping only the process specified by PID argument, if that is
1988 positive. Use PID instead of dead_child to know which process to
1989 reap. Wait for the child to die only if WNOHANG is not in
1991 (sys_select): Don't set dead_child.
1993 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1994 as it is no longer needed.
1996 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1998 (record_child_status_change): Remove the setting of
1999 record_at_most_one_child for the !WNOHANG case.
2001 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2003 Fix problems in ns port found by static checking.
2004 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2005 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2006 not to process group.
2007 (ns_select): Use emacs_write, not write, as that's more robust
2008 in the presence of signals.
2009 (fd_handler:): Check for read errors.
2011 2012-11-16 Glenn Morris <rgm@gnu.org>
2013 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2015 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2017 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2019 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2021 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2022 use the same value of thread handle.
2023 (start_timer_thread): If the timer thread exited (due to error),
2024 clean up by closing the two handles it used. Duplicate the caller
2025 thread's handle here, so it gets duplicated only once, when
2026 launching the timer thread. Set priority of the timer thread, not
2028 (getitimer): Don't duplicate the caller thread's handle here.
2031 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2033 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2036 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2038 Remove no-longer-used pty_max_bytes variable.
2039 * process.c (pty_max_bytes): Remove; unused.
2040 (send_process): Do not set it.
2042 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2044 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2045 Update dependencies.
2047 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2049 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2050 This follows up on the 2012-09-29 patch that removed indirection
2051 for the 'function' field. Reported by Sergey Vinokurov in
2052 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2054 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2056 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2057 different name, as the MS runtime does not have such a function,
2058 and probably never will.) All callers changed. Ignore DIRFD
2059 value if PATH is an absolute file name, to match Posix spec
2060 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2063 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2065 * xdisp.c (echo_area_display, redisplay_internal):
2066 Omit redundant check whether frame_garbaged is set.
2068 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2070 Use faccessat, not access, when checking file permissions (Bug#12632).
2071 This fixes a bug that has been present in Emacs since its creation.
2072 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2073 which must set some sort of record. (Torek's bug report was against
2074 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2075 same common flaw.) See Torek's Usenet posting
2076 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2077 Posted: Fri Apr 8 14:18:56 1983.
2078 * Makefile.in (LIB_EACCESS): New macro.
2080 * callproc.c (init_callproc):
2081 * charset.c (init_charset):
2082 * fileio.c (check_existing, check_executable, check_writable)
2084 * lread.c (openp, load_path_check):
2085 * process.c (allocate_pty):
2087 Use effective UID when checking permissions, not real UID.
2088 * callproc.c (init_callproc):
2089 * charset.c (init_charset):
2090 * lread.c (load_path_check, init_lread):
2091 Test whether directories are accessible, not merely whether they exist.
2092 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2093 * fileio.c (check_existing, check_executable, check_writable)
2095 Use symbolic names instead of integers for the flags, as they're
2097 (check_writable): New arg AMODE. All uses changed.
2098 Set errno on failure.
2099 (Ffile_readable_p): Use faccessat, not stat + open + close.
2100 (Ffile_writable_p): No need to call check_existing + check_writable.
2101 Just call check_writable and then look at errno. This saves a syscall.
2102 dir should never be nil; replace an unnecessary runtime check
2103 with an eassert. When checking the parent directory of a nonexistent
2104 file, check that the directory is searchable as well as writable, as
2105 we can't create files in unsearchable directories.
2106 (file_directory_p): New function, which uses 'stat' on most platforms
2107 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2108 (Ffile_directory_p, Fset_file_times): Use it.
2109 (file_accessible_directory_p): New function, which uses a single
2110 syscall for efficiency.
2111 (Ffile_accessible_directory_p): Use it.
2112 * xrdb.c (file_p): Use file_directory_p.
2113 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2114 * lread.c (openp): When opening a file, use fstat rather than
2115 stat, as that avoids a permissions race. When not opening a file,
2116 use file_directory_p rather than stat.
2117 (dir_warning): First arg is now a usage string, not a format.
2118 Use errno. All uses changed.
2119 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2120 that merely introduced a race.
2121 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2122 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2123 and similarly for the other O_* flags.
2124 * w32.c (sys_faccessat): Rename from sys_access and switch to
2125 faccessat's API. All uses changed.
2126 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2127 (magic_db): Rename from magic_file_p.
2128 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2129 char *, so that we don't have to test for file existence
2130 separately from opening the file for reading. This removes a race
2131 fixes a permission-checking problem, and simplifies the code.
2133 (file_p): Remove; no longer needed.
2135 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2137 Omit glyphs initialization at startup.
2138 * dispnew.c (glyphs_initialized_initially_p): Remove.
2139 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2140 (Fredraw_frame): Move actual code from here...
2141 (redraw_frame): ...to here. Add eassert. Adjust comment.
2142 (Fredraw_display): Use redraw_frame.
2143 * xdisp.c (clear_garbaged_frames): Likewise.
2145 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2147 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2148 passed to pint2str and pint2hrstr to be at most the size of the
2149 frame's decode_mode_spec_buffer. This avoids crashes with very
2150 large values of FIELD_WIDTH argument to decode_mode_spec.
2153 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2155 Fix a race with verify-visited-file-modtime (Bug#12863).
2156 Since at least 1991 Emacs has ignored an mtime difference of no
2157 more than one second, but my guess is that this was to work around
2158 file system bugs that were fixed long ago. Since the race is
2159 causing problems now, let's remove that code.
2160 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2161 whose time stamp is off by no more than a second. Insist that the
2162 file time stamps match exactly.
2164 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2166 * frame.h (struct frame): Convert external_tool_bar member to
2167 1-bit unsigned bitfield.
2168 * termhooks.h (struct terminal): Remove mouse_moved member since
2169 all users are long dead. Adjust comment on mouse_position_hook.
2171 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2173 Simplify by using FOR_EACH_FRAME here and there.
2174 * frame.c (next_frame, prev_frame, other_visible_frames)
2175 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2176 * w32term.c (x_window_to_scroll_bar): Likewise.
2177 * window.c (window_list): Likewise.
2178 * xdisp.c (x_consider_frame_title): Likewise.
2179 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2180 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2181 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2182 * xmenu.c (menubar_id_to_frame): Likewise.
2183 * xselect.c (frame_for_x_selection): Likewise.
2184 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2185 (x_window_to_menu_bar): Likewise.
2186 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2188 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2190 * data.c (Qdefalias_fset_function): Now static.
2192 Another tweak to vectorlike_header change.
2193 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2194 Remove, and replace all uses with ...
2195 (next_in_free_list, set_next_in_free_list):
2196 New functions, which respect C's aliasing rules better.
2198 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2200 * window.c (list4i): Rename from 'quad'. All uses changed.
2201 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2203 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2205 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2206 warning about mixing declarations and code in ISO C90.
2208 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2210 * window.c (Fsplit_window_internal): Set combination limit of
2211 new parent window to t iff Vwindow_combination_limit is t;
2212 fixing a regression introduced with the change from 2012-09-22.
2213 (Fset_window_combination_limit): Fix doc-string.
2215 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2217 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2218 amount when the scroll margins are too large. When scrolling
2219 backwards in the buffer, give up if cannot reach point or the
2220 scroll margin within a reasonable number of screen lines.
2221 Fixes point position in window under scroll-up/down-aggressively when
2222 point is positioned many lines beyond the window top/bottom.
2225 * ralloc.c (relinquish): If real_morecore fails to return memory
2226 to the system, don't crash; instead, leave the last heap
2227 unchanged and return. (Bug#12774)
2229 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2231 * lisp.h (AUTOLOADP): New macro.
2232 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2233 * data.c (Ffset): Remove special ad-advice-info handling.
2234 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2236 (Finteractive_form): Simplify.
2237 (Fquo): Don't insist on having at least 2 arguments.
2238 (Qdefalias_fset_function): New var.
2240 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2242 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2244 * nsfont.m (Qcondensed, Qexpanded): New variables.
2245 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2246 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2248 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2250 Fix recently introduced crash on MS-Windows (Bug#12839).
2251 * w32term.h (struct scroll_bar): Use convenient header.
2252 (SCROLL_BAR_VEC_SIZE): Remove.
2253 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2255 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2257 Tweak last vectorlike_header change.
2258 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2259 vectorlike object on the free list. This is introduced to avoid
2260 some (but not all) pointer casting and aliasing problems, see
2261 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2262 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2264 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2266 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2268 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2269 been removed, so remove them here also.
2271 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2273 * doc.c (Fdocumentation): Handle new property
2274 dynamic-docstring-function to replace the old ad-advice-info.
2276 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2278 * fns.c (Qeql, hashtest_eq): Now static.
2280 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2282 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2283 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2284 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2285 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2287 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2289 Use same hash function for hashfn_profiler as for hash_string etc.
2290 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2291 * lisp.h (sxhash_combine): New inline function, with the contents
2292 of the old SXHASH_COMBINE.
2293 * profiler.c (hashfn_profiler): Use it, instead of having a
2294 special hash function containing a comparison that always yields 1.
2296 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2298 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2299 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2300 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2303 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2305 * image.c (xpm_make_color_table_h): Fix compiler error because
2306 make_hash_table changed.
2308 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2310 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2312 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2314 Use ad-hoc comparison function for the profiler's hash-tables.
2315 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2316 (make_log): Use them.
2317 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2318 call Fequal any more.
2319 (Ffunction_equal): New function.
2320 (cmpfn_profiler, hashfn_profiler): New functions.

2327 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2328 (hash_lookup, hash_remove_from_table): Move assertion checking of
2329 hashfn result here. Check hash-equality before calling cmpfn.
2330 (Fmake_hash_table): Adjust call to make_hash_table.
2331 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.

2339 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2341 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2342 value of w32-scroll-lock-modifier is neither nil nor one of the
2343 known key modifiers. (Bug#12806)
2345 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2347 Shrink struct vectorlike_header to the only size field.
2348 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2350 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2351 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2352 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2353 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2354 information from the vector header. Adjust comment.
2355 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
2356 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
2358 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
2359 (struct vectorlike_header): Remove next member. Adjust comment.

2363 (sweep_string, lisp_malloc): Remove useless prototypes.
2364 (enum mem_type): Adjust comment.
2365 (NEXT_IN_FREE_LIST): New macro.
2366 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2367 (Fmake_bool_vector): Likewise.
2368 (struct large_vector): New type to represent allocation unit for
2369 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2370 (large_vectors): Change type to struct large_vector.
2371 (allocate_vector_from_block): Simplify.
2372 (PSEUDOVECTOR_NBYTES): Replace with...
2373 (vector_nbytes): ...new function. Adjust users.
2374 (sweep_vectors): Adjust processing of large vectors.
2375 (allocate_vectorlike): Likewise.
2376 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2377 Add easserts. Adjust XSETPVECTYPESIZE usage.
2378 (allocate_buffer): Use BUFFER_PVEC_INIT.
2379 (live_vector_p): Adjust to match large vector.
2380 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2381 * buffer.h (struct buffer): Add next member.
2382 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2384 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2385 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2386 (copy_hash_table): Adjust to match vector header change.
2387 * lread.c (defsubr): Use XSETPVECTYPE.

2389 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2390 (xvecsize): New command.
2392 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2394 * keyboard.c (event_to_kboard): Do not dereference
2395 frame_or_window field of SELECTION_REQUEST_EVENT
2396 and SELECTION_CLEAR_EVENT events (Bug#12814).
2397 * xterm.h (struct selection_input_event): Adjust comment.
2399 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2401 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2402 such as Scroll Lock, if the respective keys are treated as
2403 function keys, not as modifiers. This avoids destroying non-ASCII
2404 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2406 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2408 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2410 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2412 Restore some duplicate definitions (Bug#12814).
2413 This undoes part of the 2012-11-03 changes. Some people build
2414 with plain -g rather than with -g3, and they need the duplicate
2415 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2416 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2417 Define as macros, as well as as enums or as constants.
2419 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2421 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2422 to keypad keys (Bug#12816).
2424 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2426 Minor adjustments of recently-changed frame functions.
2427 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2428 known to be a frame (we're in the FRAMEP branch).
2429 * lisp.h (Qframep): Remove decl. frame.h declares this.
2430 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2431 since they're meant for Lisp fixnum values.
2433 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2435 * window.c (Fwindow_combination_limit): Revert to the only
2436 required argument and adjust docstring as suggested in
2437 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2438 by Martin Rudalics <rudalics@gmx.at>.
2440 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2442 Widely used frame validity and checking functions.
2443 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2444 * frame.c (decode_live_frame, decode_any_frame): New functions.
2445 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2446 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2447 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2448 (Fframe_pointer_visible_p): Use decode_any_frame.
2449 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2450 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2451 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2452 (Fframe_focus): Likewise. Allow zero number of arguments.
2454 (frame_buffer_list, frame_buffer_predicate): Remove.
2455 * lisp.h (frame_buffer_predicate): Remove prototype.
2456 * buffer.c (Fother_buffer): Use decode_any_frame.
2457 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2458 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2459 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2460 (Fclose_font, Ffont_info): Use decode_live_frame.
2461 * fontset.c (check_fontset_name): Likewise.
2462 * terminal.c (Fframe_terminal): Likewise.
2463 * w32fns.c (check_x_frame): Likewise.
2464 * window.c (Fminibuffer_window, Fwindow_at)
2465 (Fcurrent_window_configuration): Likewise.
2466 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2467 Likewise. Allow zero number of arguments. Adjust docstring.
2468 * dispnew.c (Fredraw_frame): Likewise.
2469 * xfaces.c (frame_or_selected_frame): Remove.
2470 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2471 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2472 (Fframe_face_alist): Use decode_live_frame.
2473 * xfns.c (check_x_frame): Likewise.
2475 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2477 * window.c (quad): New function.
2478 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2479 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2480 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2481 (Fwindow_line_height): Use it.
2482 (Fwindow_fringes): Use list3.
2483 (Fwindow_scroll_bars): Use list4.
2484 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2485 (Fwindow_combination_limit): Allow zero number of arguments.
2487 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2489 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2491 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2492 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2493 file descriptor 2 for standard error. (Bug#12805)
2495 2012-11-05 Chong Yidong <cyd@gnu.org>
2497 * process.c (wait_reading_process_output): Revert previous change.
2499 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2501 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2502 This removes code that has been obsolete since around 1990.
2503 * callproc.c (Fcall_process):
2505 * process.c (create_process):
2506 * term.c (dissociate_if_controlling_tty):
2507 Assume setsid exists.
2508 * callproc.c (child_setup): Assume setpgid exists and behaves as
2509 per POSIX.1-1988 or later.
2510 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2511 * emacs.c (shut_down_emacs):
2512 * sysdep.c (sys_suspend, init_foreground_group):
2513 Assume getpgrp behaves as per POSIX.1-1998 or later.
2514 * msdos.c (setpgrp): Remove.
2515 (tcgetpgrp, setpgid, setsid): New functions.
2516 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2517 * term.c (no_controlling_tty): Remove; unused.
2518 * w32proc.c (setpgrp): Remove.
2519 (setsid, tcgetpgrp): New functions.
2521 Simplify by assuming __fpending.
2522 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2523 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2524 Do not assume that __fpending's result fits in int.
2526 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2528 Remove EMACS_OUTQSIZE+sleep hack.
2529 * dispnew.c (update_frame_1): Remove hack for terminals slower
2530 than 2400 bps, which throttled Emacs by having it sleep.
2531 This code hasn't worked since at least 2007, when the multi-tty stuff
2532 was added, and anyway those old terminals are long dead.
2533 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2534 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2536 Fix data-loss with --version (Bug#9574).
2537 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2538 as we can't assume that emacs_strerror is initialized, and strerror
2539 is good enough here.
2540 (main): Invoke atexit earlier, to catch earlier instances of
2541 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2543 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2545 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2546 (keyDown): Remap keypad keys to X11 virtual key codes.
2548 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2550 Fix data-loss with --batch (Bug#9574).
2551 * emacs.c: Include <close-stream.h>.
2552 (close_output_streams): New function.
2553 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2554 and handles errors appropriately.
2555 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2558 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2559 The symptom is a diagnostic "GLib-WARNING **: In call to
2560 g_spawn_sync(), exit status of a child process was requested but
2561 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2562 waitpid(), so exit status can't be returned." The diagnostic
2563 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2564 The real bug is a race condition between Emacs and glib: Emacs
2565 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2566 so that glib can't find it. Work around the bug by invoking
2567 waitpid only on subprocesses that Emacs itself creates.
2568 * process.c (create_process, record_child_status_change):
2569 Don't use special value -1 in pid field, as the caller now must
2570 know the pid rather than having the callee infer it.
2571 The inference was sometimes incorrect anyway, due to another race.
2572 (create_process): Set new 'alive' member if child is created.
2573 (process_status_retrieved): New function.
2574 (record_child_status_change): Use it.
2575 Accept negative 1st argument, which means to wait for the
2576 processes that Emacs already knows about. Move special-case code
2577 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2578 processes that have already been waited for, by testing and
2579 clearing new 'alive' member.
2580 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2581 now does this internally.
2582 (handle_child_signal): Let record_child_status_change do all
2583 the work, since we do not want to reap all exited child processes,
2584 only the child processes that Emacs itself created.
2585 * process.h (Lisp_Process): New boolean member 'alive'.
2587 Omit duplicate definitions no longer needed with gcc -g3.
2588 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2589 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2590 Define only as macros. There's no longer any need to also define
2591 these symbols as enums or as constants, since we now assume
2592 gcc -g3 when debugging.
2594 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2596 * lisp.mk: Adjust comments to the fact that term/internal is now
2597 loaded from loadup.el.
2599 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2600 (msdos_fatal_signal): New function.
2601 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2604 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2605 for GCC versions before 4.
2606 (emacs_raise): Define to call msdos_fatal_signal.
2608 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2609 iterator when starting in the middle of a display or overlay
2612 2012-11-03 Chong Yidong <cyd@gnu.org>
2614 * process.c (wait_reading_process_output): Clean up the last
2617 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2619 * process.c (wait_reading_process_output): Avoid a race condition
2620 with SIGIO delivery (Bug#11536).
2622 2012-11-03 Chong Yidong <cyd@gnu.org>
2624 * buffer.c (cursor_type): Untabify docstring.
2626 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2628 * frame.h (struct frame): Drop can_have_scroll_bars member
2629 which is meaningless for a long time. Adjust comments.
2630 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2631 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2633 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2635 * window.c (decode_next_window_args): Update window arg after
2636 calling decode_live_window and so fix crash reported at
2637 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2638 by Juanma Barranquero <lekktu@gmail.com>.
2639 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2640 * font.c (Ffont_at): Likewise.
2642 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2644 * widget.c (resize_cb): New function.
2645 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2646 (EmacsFrameResize): Check if all is up to date before changing frame
2649 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2651 Implement backtrace output for fatal errors on MS-Windows.
2652 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2653 (BACKTRACE_LIMIT_MAX): New macro.
2654 (w32_backtrace): New function.
2655 (emacs_abort): Use w32_backtrace when the user chooses not to
2656 attach a debugger. Update the text of the abort dialog.
2658 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2660 Window-related stuff cleanup here and there.
2661 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2662 Use decode_any_window.
2663 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2664 * xdisp.c (Fformat_mode_line): Likewise.
2665 * font.c (Ffont_at): Use decode_live_window.
2666 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2667 * window.c (decode_next_window_args): Likewise.
2668 (decode_any_window): Remove static.
2669 * window.h (decode_any_window): Add prototype.
2670 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2671 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2674 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2676 Remove pad from struct input_event.
2677 * termhooks.h (struct input_event): Remove padding field.
2679 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2680 member is never cons for a long time. Adjust comment.
2681 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2682 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2683 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2684 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2686 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2688 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2690 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2692 Fix crash when using Emacs as commit editor for git (Bug#12697).
2693 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2694 and it is configured in conf_post.h.
2695 (Fcall_process): Don't invoke both setsid and setpgid; the former
2696 is enough, if it exists.
2697 * callproc.c (Fcall_process, child_setup):
2698 * process.c (create_process): Use setpgid.
2699 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2701 * dispnew.c (init_display): Initialize the foreground group
2702 if we are running a tty display.
2703 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2704 * lisp.h (init_foreground_group): New decl.
2705 * sysdep.c (inherited_pgroup): New static var.
2706 (init_foreground_group, tcsetpgrp_without_stopping)
2707 (narrow_foreground_group, widen_foreground_group): New functions.
2708 (init_sys_modes): Narrow foreground group.
2709 (reset_sys_modes): Widen foreground group.
2711 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2713 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2715 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2717 * minibuf.c (read_minibuf): Restore current buffer since
2718 choose_minibuf_frame calling Fset_frame_selected_window may
2719 change it (Bug#12766).
2721 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2723 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2725 2012-10-30 Kenichi Handa <handa@gnu.org>
2727 * font.c (Ffont_at): If WINDOW is specified and it is not
2728 displaying the current buffer, signal an error.
2730 2012-10-29 Daniel Colascione <dancol@dancol.org>
2732 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2733 In preparation for fixing bug#12739, move these functions from
2736 * coding.h, coding.c: ... to here, and compile them only when
2737 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2738 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2740 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2742 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2743 (timer_loop, getitimer, setitimer): Use it instead of
2744 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2746 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2749 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2751 * nsterm.m (NO_APPDEFINED_DATA): New define.
2752 (last_appdefined_event_data): New variable
2753 (last_appdefined_event): Remove.
2754 (ns_select): Initialize t from last_appdefined_event_data instead
2755 of [last_appdefined_event data1].
2756 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2757 remove last_appdefined_event (Bug#12698).
2759 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2761 * frame.c (x_set_font): Catch internal error.
2763 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2765 Avoid overflow in w32 implementation of interval timers.
2766 When possible, for ITIMER_PROF count only times the main thread
2768 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2769 'volatile ULONGLONG' types. All the other data which was
2770 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2771 (GetThreadTimes_Proc): New typedef.
2772 (w32_get_timer_time): New function, returns a suitable time value
2774 (timer_loop): Enter critical section when accessing ULONGLONG
2775 values of the itimer_data struct, as these accesses are no longer
2776 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2777 Remove unused variable.
2778 (init_timers): Initialize s_pfn_Get_Thread_Times.
2779 (start_timer_thread): Don't assign itimer->caller_thread here.
2780 (getitimer): Assign itimer->caller_thread here.
2781 (setitimer): Always call getitimer to get the value of ticks_now.
2782 (sys_spawnve): Avoid compiler warning about format mismatch.
2784 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2786 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2787 mouse movement events if the menu bar is active. This avoids
2788 producing a busy "hour-glass" cursor by Windows if the mouse
2789 pointer is positioned over a tooltip shown for some menu item.
2791 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>

2839 (get_lface_attributes_no_remap, get_lface_attributes)
2840 (lface_fully_specified_p, x_supports_face_attributes_p)
2841 (tty_supports_face_attributes_p, face_fontset, realize_face)
2842 (realize_x_face, realize_tty_face):
2843 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2844 merely Lisp_Object *. This is more informative and avoids
2845 a warning on OpenBSD about accessing beyond an object's size.

3199 which is broken under remote desktop, calculate the number of

3266 Use `report_file_error' instead of `error' in order to better
3267 inform users of what went wrong. Increase NTGUI_UNICODE file
3268 dialog box file name length to 32k, the maximum allowed by the NT
3271 * w32common.h: New file.
3272 (ROUND_UP, ROUND_DOWN, get_page_size)
3273 (get_allocation_unit, get_processor_type, get_w32_major_version)
3274 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3275 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3276 (OS_NT, os_subtype, cache_system_info): Move here.
3278 * unexw32.c, unexcw.c: Include w32common.h.
3280 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3281 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3282 to call syms_of_w32select.
3284 * cygw32.h: Remove obsolete EXFUN declarations.
3286 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3288 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3289 of w32inevt.o from SOME_MACHINE_OBJECTS.
3291 2012-10-08 Daniel Colascione <dancol@dancol.org>
3293 * image.c: Permanent fix for JPEG compilation issue --- limit
3294 jpeglib `boolean' redefinition to Cygwin builds.
3296 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3298 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3300 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3303 2012-10-08 Daniel Colascione <dancol@dancol.org>
3305 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3306 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3307 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3308 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3309 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3310 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3311 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3312 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3313 now a supported configuration.
3315 * Makefile.in: consolidate image variables into LIBIMAGE; add
3316 W32_OBJ and W32_LIBS. Compile new files.
3319 (_DebPrint) declare tracing facility for W32 debugging. We need
3320 to unify tracing later.
3322 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3323 unconditional use of W32 Unicode functions. Cygwin runs only on
3324 100% Unicode operating systems.
3326 * cygw32.c: New file. Define Cygwin-specific facilities.
3327 (Fcygwin_convert_path_to_windows)
3328 (Fcygwin_convert_path_from_windows): New user functions for
3329 accessing Cygwin path-munging routines.
3331 * cygw32.h: New file.
3332 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3333 UTF-16LE strings temporarily inside non-Lisp-visible string
3336 (w32_strerror): Just what it says on the tin.
3338 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3339 also run for Cygwin; both systems have the same problem with using
3340 GUI facilities in a forked child. Also call syms_of_cygw32,
3341 syms_of_w32select in correct places.
3343 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3344 needs fork-then-exec for daemon launching.
3346 * font.h: Include frame.h.
3348 * image.c: Use the image library cache machinery only when we're
3349 compiling for native WINDOWSNT; Cygwin can use shared libraries
3350 like any other Unixlike system.
3352 * keyboard.c: Clarify a comment regarding the input loop.
3354 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3355 functions directly instead of trying to detect at runtime that our
3356 host operating system supports them. We make this change for two
3357 reasons: Cygwin lacks support for the multibyte character
3358 conversion functions used by the legacy menu code, and Cygwin
3359 never needs to rely on non-Unicode APIs.
3361 * unexw32.c (hinst): Declare extern.
3363 * w32.c: Change header order;
3364 (w32_strerror): Move to w32fns.c because we need it for
3365 non-WINDOWSNT builds.
3367 * w32.h: Add #error macro to make sure we don't include w32.h for
3368 Cygwin builds. Remove w32select declarations.
3370 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3371 w32fns.c. w32console.c is WINDOWSNT-only.
3373 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3374 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3376 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3377 (w32_major_version, w32_minor_version, w32_build_number)
3378 (os_subtype, sound_type): Define here
3379 (w32_defined_color): Make color parameter const for consistency
3380 with other _defined_color functions.
3381 (w32_createwindow): Unconditionally call w32_init_class instead of
3382 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3383 through the code is complex and unnecessary because class
3384 registration is practically free.
3385 (w32_name_of_message): New EMACSDEBUG-only function.
3386 (Fset_message_beep): Move here
3387 (Fx_open_connection): Require that the display name for Windows be
3388 "w32" for consistency, emacsclient disambiguation, and maybe, one
3389 day, multi-window-system support.
3390 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3391 Cygwin files for W32 GUI facilities, since these clearly don't
3392 expect Cygwin names.
3393 (_DebPrint): Define.
3394 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3395 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3396 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3397 (w32_last_error): Remove.
3399 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3401 * w32heap.c (syspage_mask): Declare here.
3402 (cache_system_info): Remove.
3404 * w32inevt.c (faked_key): Define globally, not statically.
3405 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3406 (w32_console_toggle_lock_key): Move to w32fns.c.
3408 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3410 * w32proc.c (_DebPrint): Move to w32fns.c.
3411 * w32select.c: Include string.h, stdio.h for Cygwin.
3412 * w32select.h: New File.
3414 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3416 (w32_message_fd): New variable. Under Cygwin, holds the file
3417 descriptor the system used to tell us about pending thread
3420 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3421 that prevented compilation under non-WINDOWSNT systems.
3423 (w32_initialize): Open /dev/windows and assign it to
3424 w32_message_fd. Provide w32 feature.
3426 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3427 (WM_EMACS_INPUT_READY): add.
3428 (prepend_msg, w32_message_fd): Declare globally.
3431 (keyboard_handle): Use only when WINDOWSNT.
3432 (notify_msg_ready): New function. Posts a message to the main
3433 thread's message queue under CYGWIN, which wakes up the main
3434 thread from select(2) by making the /dev/windows file descriptor
3435 ready. Under WINDOWSNT, it sets an event the same way the old
3438 (post, prepend_msg): Actually call notify_msg_ready instead of
3439 setting the input event directly.
3441 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3443 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3444 but it still has blocs in it, don't return it to the system,
3445 instead of aborting. (Bug#12402)
3447 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3449 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3451 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3452 MAC_OS_X_VERSION_10_6.
3453 (syms_of_nsterm): Remove comment about Panther and above for
3455 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3456 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3457 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3459 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3460 MAC_OS_X_VERSION_10_4.
3462 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3463 MAC_OS_X_VERSION_10_2.
3465 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3467 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3468 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3470 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3471 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3472 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3473 Remove ns_in_resize check.
3474 (ns_clear_frame_area): Remove resize handle code.
3476 * nsfns.m (ns_in_resize): Remove.
3477 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3478 Remove ns_in_resize check.
3480 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3482 Improve sys_siglist detection.
3483 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3484 defined as a macro, as is done in Solaris.
3485 (sys_siglist_entries): New macro.
3486 (save_strsignal): Use it.
3487 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3488 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3490 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3492 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3493 fullscreen/Fullscreen.
3495 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3496 tobar_height is new.
3498 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3499 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3500 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3501 (windowDidResize:): Check for correct window if old style fullscreen.
3502 Capitalize word in comment. Remove incorrect comment.
3503 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3504 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3505 error in drawing background.
3506 (toggleFullScreen:): Remove comment. Rearrange calls.
3507 Set toolbar values to zero, save old height in tobar_height.
3508 Restore tool bar height when leaving fullscreen.
3509 (canBecomeMainWindow): New function.
3511 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3513 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3515 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3517 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3519 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3520 that time stamps of directories could also be changed.
3521 Don't request the too broad GENERIC_WRITE, only the more restrictive
3522 FILE_WRITE_ATTRIBUTES access rights.
3524 * fileio.c (Fset_file_times): Special-case ignoring errors for
3525 directories only on MSDOS, not on MS-Windows.
3527 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3529 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3531 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3533 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3534 see whether CreateFile failed.
3536 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3538 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3539 to avoid similar races.
3540 * keyboard.c (pending_signals): Now bool, not int.
3542 Port timers to OpenBSD, plus check for timer failures.
3543 OpenBSD problem reported by Han Boetes.
3544 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3546 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3547 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3548 like OpenBSD, which has timer_settime but does not declare it.
3549 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3550 whether to use itimerspec-related primitives. All uses of
3551 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3553 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3555 * profiler.c (handle_profiler_signal): Fix a malloc race
3556 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3558 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3560 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3562 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3564 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3565 consistent with the change in return value of 'safe_strsignal'.
3567 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3569 Prefer plain 'static' to 'static inline' (Bug#12541).
3570 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3571 (bidi_set_sor_type, bidi_push_embedding_level)
3572 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3573 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3574 (bidi_cache_search, bidi_cache_ensure_space)
3575 (bidi_cache_iterator_state, bidi_cache_find)
3576 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3577 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3578 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3579 Now 'static', not 'static inline'.
3581 Count overruns when profiling; change units to ns.
3582 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3583 Give extra weight to samples after overruns, to attempt to count
3584 the time more accurately.
3585 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3586 the underlying primitives nominally do ns.
3587 (Fprofiler_cpu_start): Document the change. Mention that
3588 the sampling intervals are only approximate.
3590 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3592 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3594 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3595 case for the special 0 coding-system.
3597 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3598 (Fmake_overlay): Remove redundant tests.
3599 (fix_start_end_in_overlays): Remove redundant recentering.
3601 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3603 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3604 Update dependencies.
3606 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3608 Fix a malloc race condition involving strsignal.
3609 A signal can arrive in the middle of a malloc, and Emacs's signal
3610 handler can invoke strsignal, which can invoke malloc, which is
3611 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3612 Fix it by altering the signal handler so that it does not invoke
3614 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3615 * process.c (status_message): Use const pointer, in case strsignal
3616 is #defined to safe_strsignal.
3617 * sysdep.c (sys_siglist, init_signals): Always define and
3618 initialize a substitute sys_siglist if the system does not define
3619 one, even if HAVE_STRSIGNAL.
3620 (safe_strsignal): Rename from strsignal. Always define,
3621 using sys_siglist. Return a const pointer.
3622 * syssignal.h (safe_strsignal): New decl.
3623 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3625 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3627 * w32proc.c (timer_loop): Fix code that waits for timer
3628 expiration, to avoid high CPU usage.
3630 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3632 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3633 (sweep_weak_table): Remove redundant prototypes.
3635 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3637 * emacs.c: Move the inclusion of TERM_HEADER after including
3638 windows.h on WINDOWSNT. This avoids compilation problems with
3641 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3643 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3644 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3645 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3646 as the previous version used 'void *'.
3648 * ralloc.c (ROUNDUP): Fix last change.
3649 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3652 * w32proc.c <disable_itimers>: New static flag.
3653 (init_timers): Initialize it to zero, after creating the critical
3654 sections used by the timer threads.
3655 (term_timers): Set to 1 before deleting the critical sections.
3656 (getitimer, setitimer): If disable_itimers is non-zero, return an
3657 error indication without doing anything. Reported by Fabrice
3658 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3659 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3661 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3664 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3665 term_ntproc after all the other bookkeeping, to get timers working
3666 as long as possible.
3668 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3670 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3671 Suggested by Juri Linkov in
3672 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3674 Prefer plain 'static' to 'static inline' (Bug#12541).
3675 With static functions, modern compilers inline pretty well by
3676 themselves; advice from programmers often hurts as much as it helps.
3677 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3678 this change shrinks the text size of the Emacs executable by 1.1%
3679 without affecting CPU significantly in my benchmark.
3680 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3973 (handle_profiler_signal): Rename from sigprof_handler_1,
3974 for consistency with other handlers. Do not check whether
3975 cpu_log is a hash-table if garbage collecting, since it

3978 for consistency with other handlers.
3979 (setup_cpu_timer): New function, with much of what used to be in

3981 Prefer timer_settime if available, and prefer
3982 thread cputime clocks, then process cputime clocks, then
3983 monotonic clocks, to the old realtime clock. Use make_timeval
3984 to round more-correctly when falling back to setitimer.
3985 (Fprofiler_cpu_start): Use it.
3986 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4053 Since this stuff is now private to charset.c, there's no need for
4054 a public macro and no need to inline by hand.

4202 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4204 Move pid_t related decls out of lisp.h.
4205 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4206 (interruptible_wait_for_termination):
4207 Move these decls from lisp.h to syswait.h, since they use pid_t.
4208 Needed on FreeBSD; see Herbert J. Skuhra in
4209 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

4256 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4258 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4259 fatal_error_backtrace.
4261 * w32proc.c (sys_kill): Undo last change: don't do anything when
4262 invoked to deliver SIGABRT to our own process. This is now
4263 handled by emacs_raise.
4265 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4267 * w32term.c (w32_read_socket): Remove leftover reference to
4268 interrupt_input_pending.
4270 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4272 Do not use SA_NODEFER.
4273 Problem reported by Dani Moncayo in
4274 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4276 * sysdep.c (emacs_abort): Do not reset signal handler.
4277 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4278 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4279 wanted even on POSIXish hosts, and it doesn't work on Windows.
4281 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4283 * xterm.c (x_term_init): Call fixup_locale before and after calling
4284 gtk_init (Bug#12392).
4286 2012-09-23 Chong Yidong <cyd@gnu.org>
4288 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4289 Vdynamic_library_alist.
4291 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4292 (Fgnutls_available_p): Caller changed.
4294 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4295 (Flibxml_parse_xml_region): Likewise.
4297 * dispextern.h (struct image_type): Remove arg from init function.
4299 * image.c (Finit_image_library, lookup_image_type)
4300 (define_image_type): Remove now-unneeded second arg.
4301 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4302 (init_tiff_functions, init_gif_functions, init_svg_functions):
4303 Arglist and w32_delayed_load calling convention changed.
4304 (gs_type): Remove init_gs_functions; there is no such function.
4305 (valid_image_p, make_image): Fix caller to lookup_image_type.
4307 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4309 Simplify and avoid signal-handling races (Bug#12471).
4311 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4312 Avoid recursive loop if there's a fatal error in the function itself.
4313 * atimer.c (pending_atimers):
4314 * blockinput.h: Don't include "atimer.h"; no longer needed.
4315 (interrupt_input_pending): Remove. All uses removed.
4316 pending_signals now counts both atimers and ordinary interrupts.
4317 This is less racy than having three separate pending-signal flags.
4318 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4320 Rename from their upper-case counterparts BLOCK_INPUT,
4321 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4322 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4323 This makes it easier to access volatile variables more accurately.
4324 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4325 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4326 that's more reliable if the code is buggy and sets
4327 interrupt_input_blocked to a negative value. All uses changed.
4328 * atimer.c (deliver_alarm_signal):
4329 Remove. No need to deliver this to the parent; any thread can
4330 handle this signal now. All uses replaced by underlying handler.
4331 * atimer.c (turn_on_atimers):
4332 * dispnew.c (handle_window_change_signal):
4333 * emacs.c (handle_danger_signal):
4334 * keyboard.c (kbd_buffer_get_event):
4335 Don't reestablish signal handler; not needed with sigaction.
4336 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4338 Rework to avoid unnecessary accesses to volatile variables.
4339 (UNBLOCK_INPUT_TO): Now a function.
4340 (totally_unblock_input, unblock_input): New decls.
4341 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4342 (init_data): Remove. Necessary stuff now done in init_signal.
4343 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4344 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4345 (fatal_error_code): Remove; no longer needed.
4346 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4347 it doesn't always backtrace. All uses changed. No need to reset
4348 signal to default, since sigaction and/or die does that for us now.
4349 Use emacs_raise (FOO), not kill (getpid (), FOO).
4350 (main): Check more-accurately whether we're dumping.
4351 Move fatal-error setup to sysdep.c
4352 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4353 * gtkutil.c (xg_get_file_name, xg_get_font):
4354 Remove no-longer-needed signal-mask manipulation.
4355 * keyboard.c, process.c (POLL_FOR_INPUT):
4356 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4357 * keyboard.c (read_avail_input): Remove.
4358 All uses replaced by gobble_input.
4359 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4360 (kbd_buffer_store_event_hold, gobble_input):
4361 (record_asynch_buffer_change) [USABLE_SIGIO]:
4362 (store_user_signal_events):
4363 No need to mess with signal mask.
4364 (gobble_input): If blocking input and there are terminals, simply
4365 set pending_signals to 1 and return. All hooks changed to not
4366 worry about whether input is blocked.
4367 (process_pending_signals): Clear pending_signals before processing
4368 them, in case a signal comes in while we're processing.
4369 By convention callers now test pending_signals before calling us.
4370 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4371 New functions, to support changes to blockinput.h.
4372 (handle_input_available_signal): Now extern.
4373 (reinvoke_input_signal): Remove. All uses replaced by
4375 (quit_count): Now volatile, since a signal handler uses it.
4376 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4377 All callers changed. Block SIGINT only if not already blocked.
4378 Clear sigmask reliably, even if Fsignal returns, which it can.
4379 Omit unnecessary accesses to volatile var.
4380 (quit_throw_to_read_char): No need to restore sigmask.
4381 * keyboard.c (gobble_input, handle_user_signal):
4382 * process.c (wait_reading_process_output):
4383 Call signal-handling code rather than killing ourselves.
4384 * lisp.h: Include <float.h>, for...
4385 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4386 (pending_signals): Now volatile.
4387 (syms_of_data): Now const if IEEE floating point.
4388 (handle_input_available_signal) [USABLE_SIGIO]:
4389 (terminate_due_to_signal, record_child_status_change): New decls.
4390 * process.c (create_process): Avoid disaster if memory is exhausted
4391 while we're processing a vfork, by tightening the critical section
4393 (send_process_frame, process_sent_to, handle_pipe_signal)
4394 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4396 (send_process): No need for setjmp/longjmp any more, since the
4397 SIGPIPE stuff is now gone. Instead, report an error if errno
4399 (record_child_status_change): Now extern. PID and W are now args.
4400 Return void, not bool. All callers changed.
4401 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4402 Remove. All uses removed. This bug should be fixed now in a
4404 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4405 and record the child status change directly. This avoids the
4406 need to futz with the signal mask.
4407 (process_fatal_action): Move here from emacs.c.
4408 (emacs_sigaction_flags): New function, containing
4409 much of what used to be in emacs_sigaction_init.
4410 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4411 caught by emacs, to make races less likely.
4412 (deliver_process_signal): Rename from handle_on_main_thread.
4414 (BACKTRACE_LIMIT_MAX): Now at top level.
4415 (thread_backtrace_buffer, threadback_backtrace_pointers):
4417 (deliver_thread_signal, deliver_fatal_thread_signal):
4418 New functions, for more-accurate delivery of thread-specific signals.
4419 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4420 (deliver_arith_signal): Handle in this thread, not
4421 in the main thread, since it's triggered by this thread.
4422 (maybe_fatal_sig): New function.
4423 (init_signals): New arg DUMPING so that we can be more accurate
4424 about whether we're dumping. Caller changed.
4425 Treat thread-specific signals differently from process-general signals.
4426 Block all signals while handling fatal error; that's safer.
4427 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4429 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4430 Ignore SIGPIPE unless batch.
4431 (emacs_backtrace): Output backtrace for the appropriate thread,
4432 which is not necessarily the main thread.
4433 * syssignal.h: Include <stdbool.h>.
4434 (emacs_raise): New macro.
4435 * xterm.c (x_connection_signal): Remove; no longer needed
4436 now that we use sigaction.
4437 (x_connection_closed): No need to mess with sigmask now.
4438 (x_initialize): No need to reset SIGPIPE handler here, since
4439 init_signals does this for us now.
4441 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4443 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4444 background rect may be larger (Bug#12245).
4446 2012-09-23 Chong Yidong <cyd@gnu.org>
4448 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4450 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4452 * .gdbinit: Just stop at fatal_error_backtrace.
4453 See Stefan Monnier's request in
4454 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4455 Remove no-longer-used query of system type.
4457 2012-09-22 Chong Yidong <cyd@gnu.org>
4459 * search.c (Freplace_match): Doc fix (Bug#12325).
4461 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4463 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4464 (Fline_end_position): Doc fix.
4466 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4468 2012-09-22 Chong Yidong <cyd@gnu.org>
4470 * dispextern.h (struct image_type): Add new slot, storing a type
4471 initialization function.
4473 * image.c (define_image_type): Call the image initializer function
4474 if it is defined. Arguments and return value changed.
4475 (valid_image_p, make_image): Callers changed.
4476 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4477 (gif_type, imagemagick_type, svg_type, gs_type):
4478 Add initialization functions.
4479 (Finit_image_library): Call lookup_image_type.
4480 (CHECK_LIB_AVAILABLE): Macro deleted.
4481 (lookup_image_type): Call define_image_type here, rather than via
4482 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4483 (syms_of_image): Move define_image_type calls for xbm_type and
4484 pbm_type to lookup_image_type.
4486 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4488 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4489 'idle_timers' from here ...
4490 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4491 lists, to avoid infloops when the timer does something stupid,
4492 like reinvoke itself with the same or smaller time-out.
4495 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4497 * window.c (Fsplit_window_internal): Handle only Qt value of
4498 Vwindow_combination_limit separately.
4499 (Qtemp_buffer_resize): New symbol.
4500 (Vwindow_combination_limit): New default value.
4503 2012-09-22 Eli Zaretskii <eliz@gnu.org>

4506 the new overlay string. (Bug#10159)
4508 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4510 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4511 or that fprintf is async-signal-safe. POSIX doesn't require
4514 2012-09-22 Chong Yidong <cyd@gnu.org>
4516 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4519 2012-09-22 Kenichi Handa <handa@gnu.org>
4521 * composite.c (composition_reseat_it): Handle the case that a
4522 grapheme cluster is not covered by a single font (Bug#12352).
4524 2012-09-21 Chong Yidong <cyd@gnu.org>
4526 * image.c (define_image_type): Avoid adding duplicate types to
4527 image_types (Bug#12463). Suggested by Jörg Walter.
4529 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4531 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4532 (print_load_command_name): Add case LC_DATA_IN_CODE.
4533 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

4537 * eval.c (Frun_hook_with_args_until_success)
4538 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4540 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4542 * fileio.c (Ffile_selinux_context): Only call freecon when
4543 lgetfilecon succeeded.
4544 (Fset_file_selinux_context): Likewise. (Bug#12444)
4546 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4548 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4549 reordering, locate the cursor by calling set_cursor_from_row; if
4550 that fails, clear the desired glyph matrix before returning a
4551 failure indication to the caller. Fixes leaving garbled display
4552 when fast scrolling with a down-key. (Bug#12403)
4553 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4554 scrolling through multibyte text.
4556 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4558 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4559 calling mark_vectorlike since that's the one that marks the window.
4560 (mark_discard_killed_buffers): Mark the final cdr.
4561 * window.h (struct window): Move prev/next_buffers to the
4562 non-standard fields.
4563 * window.c (make_window): Initialize prev/next_buffers manually.
4565 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4567 Omit unused arg EXPECTED from socket hooks.
4568 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4569 * nsterm.m (ns_term_init):
4570 * termhooks.h (struct terminal.read_socket_hook):
4571 * w32inevt.c (w32_console_read_socket):
4572 * w32term.c (w32_read_socket):
4573 * xterm.c (XTread_socket):
4574 Omit unused arg EXPECTED. All callers changed.
4575 (store_user_signal_events): Return void, not int, since callers no
4576 longer care about the return value. All uses changed.
4578 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4580 * w32gui.h (XParseGeometry): Do not declare.
4582 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4584 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4585 Ignore 'expected'. See Eli Zaretskii in

4588 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4589 (XParseGeometry): Now static. Substitute extremal values for
4590 values that are out of range.
4592 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4594 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4596 * nsfns.m (XParseGeometry): Remove.
4597 (Fx_create_frame): Call x_set_offset to correctly interpret
4598 top_pos in geometry.
4600 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4601 (Fx_parse_geometry): If there is a space in string, call
4602 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4604 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4606 * search.c (scan_buffer): Use character positions in calls to
4607 region_cache_forward and region_cache_backward, not byte
4608 positions. (Bug#12196)
4610 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4611 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4613 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4614 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4615 emacs_blocked_malloc, now deleted.
4617 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4619 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4620 The workaround was for improving performance on Solaris 2.4, but
4621 is getting in the way now. Emacs will still work if someone is
4622 still running Solaris 2.4 in a museum somewhere; Sun dropped
4623 support for Solaris 2.4 in 2003.
4624 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4625 * process.c (create_process) [HAVE_WORKING_VFORK]:
4626 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4627 since Emacs no longer uses vfork on that platform.
4629 2012-09-17 Glenn Morris <rgm@gnu.org>
4631 * emacs.c: Use COPYRIGHT.
4633 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4635 Remove configure's --without-sync-input option (Bug#12450).
4636 When auditing signal-handling in preparation for cleaning it up,
4637 I found that SYNC_INPUT has race conditions and would be a real
4638 pain to fix. Since it's an undocumented and deprecated
4639 configure-time option, now seems like a good time to remove it.
4640 Also see <http://bugs.gnu.org/11080#16>.
4641 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4642 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4643 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4644 (malloc_hysteresis):
4645 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4646 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4647 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4648 (dont_register_blocks, bytes_used_when_reconsidered)
4649 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4650 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4651 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4652 Remove. All uses removed.
4653 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4654 implementation, one that depends on whether the new macro
4655 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4657 * atimer.c (run_timers, handle_alarm_signal):
4658 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4659 (handle_async_input, process_pending_signals)
4660 (handle_input_available_signal, init_keyboard):
4661 * nsterm.m (ns_read_socket):
4662 * process.c (wait_reading_process_output):
4663 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4664 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4666 * xterm.c (XTread_socket):
4668 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4669 * eval.c (handling_signal): Remove. All uses removed.
4670 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4671 All uses replaced with the SYNC_INPUT version.
4672 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4674 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4677 * font.c (Ffont_shape_gstring): Remove unused local.
4679 2012-09-16 Glenn Morris <rgm@gnu.org>
4681 * Makefile.in (clean): No longer run nextstep's clean.
4683 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4685 (ns-app): Move here from ns.mk, and simplify.
4686 (clean): Simplify nextstep entry.
4687 * ns.mk: Remove file.
4689 2012-09-17 Kenichi Handa <handa@gnu.org>
4691 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4692 not covert the last few charactes.
4694 2012-09-16 Kenichi Handa <handa@gnu.org>
4696 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4697 here, but just check the validity of glyphs in the glyph-string.
4699 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4701 * window.c (Fwindow_parameter, Fset_window_parameter):
4702 Accept any window as argument (Bug#12452).
4704 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4706 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4707 to ns_term_init to avoid memory leak.
4709 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4710 explicit retain/release.
4711 (ns_term_init): Only allow one display. Initialize outerpool and
4714 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4716 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4717 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4718 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4719 the Microsoft problem in a different way, by altering ../nt/config.nt.
4721 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4736 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4737 by lisp.h. This completes removal of setjmp.h inclusion
4738 erroneously announced in the previous commit. (Bug#12446)
4740 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4743 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4744 not defined as a macro. The latter happens on MS-Windows.
4747 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4749 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4750 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4751 Some instances of '#include <setjmp.h>' removed, if the
4752 only reason for the instance was because "lisp.h" was included.
4753 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4754 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4755 and _longjmp with the new symbols. Emacs already uses _setjmp if
4756 available, so this change affects only POSIXish hosts that have
4757 sigsetjmp but not _setjmp, such as some versions of Solaris and
4758 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4759 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4760 (png_load_body) [HAVE_PNG]:
4761 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4762 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4763 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4764 since PNG requires jmp_buf. This is the only exception to the
4765 general rule that we now use sys_setjmp and sys_longjmp.
4766 This exception is OK since this code does not change the signal
4767 mask or longjmp out of a signal handler.
4769 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4771 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4772 Include "syssignal.h", for 'main_thread'.
4774 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4776 Avoid out-of-range marker position (Bug#12426).
4777 * insdel.c (replace_range, replace_range_2):
4778 Adjust markers before overlays, as suggested by comments.
4779 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4780 Remove redundant check before calling offset_intervals.
4782 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4784 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4785 current buffer (Bug#12387).
4787 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4789 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4791 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4793 Use a more backwards-compatible timer format (Bug#12430).
4794 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4795 vector element, not from the 4th, since PSECS is now at the end.
4796 (Fcurrent_idle_time): Doc fix.
4798 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4800 Function to mark objects and remove killed buffers at once.
4801 * alloc.c (discard_killed_buffers): Rename to ...
4802 (mark_discard_killed buffers) ... new name. Add marking
4803 of remaining objects. Fix comment. Adjust users.
4804 (mark_object): Do not touch frame buffer lists here.
4805 * frame.c (delete_frame): Reset frame buffer lists here.
4807 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4809 Better workaround for GNOME bug when --enable-gcc-warnings.
4810 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4811 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4812 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4814 Simplify SIGIO usage (Bug#12408).
4815 The code that dealt with SIGIO was crufty and confusing, e.g., it
4816 played tricks like "#undef SIGIO" but these tricks were not used
4817 consistently. Simplify mostly by not #undeffing standard symbols,
4818 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4819 or not as we please) rather than "defined SIGIO" (standard symbol
4820 that we probably shouldn't #undef).
4821 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4822 Modules that need it can include it.
4823 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4824 * dispextern.h (ignore_sigio): New decl.
4825 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4826 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4827 * emacs.c (shut_down_emacs):
4828 * keyboard.c (kbd_buffer_store_event_hold):
4829 Use ignore_sigio rather than invoking 'signal' directly.
4830 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4832 (FIONREAD, SIGIO): Do not #undef.
4833 (tty_read_avail_input): Use #error rather than a syntax error.
4834 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4835 for I_PIPE, used by SETUP_SLAVE_PTY.
4836 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4837 * sysdep.c (croak): Remove; no longer needed. This bit of
4838 temporary code, with Fred N. Fish's comment that it's temporary,
4839 has been in Emacs since at least 1992!
4840 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4841 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4842 * syssignal.h (croak): Remove decl.
4843 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4844 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4845 now that we're termios-only.
4846 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4847 * term.c (dissociate_if_controlling_tty): Use #error rather than
4850 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4851 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4852 to work around GNOME bug 683906.
4853 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4854 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4855 This works around GCC bug 54561.
4857 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4859 More fixes for 'volatile' and setjmp/longjmp.
4860 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4861 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4862 (png_load_body) [HAVE_PNG]:
4863 (jpeg_load_body) [HAVE_JPEG]:
4864 New function, with most of the old parent function's body.
4865 (png_load) [HAVE_PNG]:
4866 (jpeg_load) [HAVE_JPEG]:
4867 Invoke the new function, to avoid longjmp munging our locals.
4868 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4869 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4870 longjmp is passed 2, as the C standard doesn't guarantee this.
4871 Instead, store the failure code into mgr->failure_code.
4873 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4875 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4876 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4877 (syms_of_keyboard): Remove support for unread-command-char.
4879 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4881 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4882 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4883 violation. (Bug#12426)
4885 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4887 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4889 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4891 * eval.c: Add `inhibit-debugger'.
4892 (Qinhibit_debugger): New symbol.
4893 (call_debugger): Bind it instead of Qdebug_on_error.
4894 (maybe_call_debugger): Test Vinhibit_debugger.
4895 (syms_of_eval): Define inhibit-debugger.
4896 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4897 (syms_of_xdisp): Remove inhibit-debug-on-message.
4899 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4901 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4902 If a nonvolatile local variable is written before a _longjmp to
4903 the frame containing the variable, and is read after the _longjmp,
4904 the value read is indeterminate. Some local variables of type
4905 'struct handler' and 'struct catchtag' are used in this way, so
4906 mark each of their slots as volatile if the slot can be set before
4907 _longjmp and read afterwards.
4908 * lisp.h (struct handler): var and chosen_clause are now volatile.
4909 (struct catchtag): val, next, and pdlcount are now volatile.
4911 * bidi.c (bidi_push_it, bidi_pop_it):
4912 * fns.c (copy_hash_table):
4913 * image.c (define_image_type):
4914 * keyboard.c (kbd_buffer_store_event_hold):
4915 * process.c (Fprocess_send_eof):
4916 * xfaces.c (x_create_gc) [HAVE_NS]:
4917 * xgselect.c (xg_select):
4918 Prefer assignment to memcpy when either will do.
4920 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4921 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4922 time an item is removed. No need to mark this function 'inline';
4923 the compiler knows better than we do.
4925 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4927 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4928 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4929 to change_frame_size (Bug#12388).
4930 (windowDidResize:): Pass YES to updateFrameSize.
4932 * nsterm.h: Add delay parameter to updateFrameSize.
4934 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4936 Discard killed buffers from deleted window and frame objects.
4937 This reduces an amount of references to killed buffers and
4938 helps GC to reclaim them faster.
4939 * alloc.c (discard_killed_buffers): New function.
4940 (mark_object): Use it for deleted windows and frames.
4941 (mark_object): If symbol's value is set up for a killed buffer
4942 or deleted frame, restore its global binding.
4943 * data.c (swap_in_global_binding): Add GC notice.
4944 (swap_in_symval_forwarding): Use convenient set_blv_where.
4945 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4946 * window.h: ... to here.
4948 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4950 Convenient macro to check whether the buffer is live.
4951 * buffer.h (BUFFER_LIVE_P): New macro.
4952 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4953 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4955 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4957 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4958 composition cases (Bug#12364).
4960 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4961 overhang of succeeding glyphs overlapping box cursor.
4963 * w32term.c (x_draw_glyph_string): Likewise.
4965 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4967 Simplify, document, and port floating-point (Bug#12381).
4968 The porting part of this patch fixes bugs on non-IEEE platforms
4969 with frexp, ldexp, logb.
4970 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4972 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4973 support, by removing commented-out code and briefly listing the
4974 C89 functions excluded. The commented-out stuff was confusing
4975 maintenance, e.g., we thought we needed cbrt but it was commented out.
4976 (logb): Remove decl; no longer needed.
4977 (isfinite): New macro, if not already supplied.
4978 (isnan): Don't replace any existing macro.
4979 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4980 are present on all C89 platforms.
4981 (Ffrexp): Do not special-case zero, as frexp does the right thing
4983 (Flogb): Do not use logb, as it doesn't have the desired meaning
4984 on hosts that use non-base-2 floating point. Instead, stick with
4985 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4986 frexp, to avoid getting an unspecified result.
4988 * xdisp.c (Qinhibit_debug_on_message): Now static.
4990 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4992 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4993 NSBezierPath (Bug#12131).
4995 2012-09-10 Chong Yidong <cyd@gnu.org>
4997 * fns.c (Fdelq, Fdelete): Doc fix.
4999 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5001 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5002 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5004 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5006 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5007 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5010 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5012 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5013 left fringe if the window has a left margin. This avoids leaving
5014 traces of the cursor because its leftmost pixel is not drawn over.
5016 * dispnew.c (update_window_line): When the left margin area of a
5017 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5018 that screen line. (Bug#12277)
5020 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5022 Assume C89 or later for math functions (Bug#12381).
5023 This simplifies the code, and makes it a bit smaller and faster,
5024 and (most important) makes it easier to clean up signal handling
5025 since we can stop worring about floating-point exceptions in
5026 library code. That was a problem before C89, but the problem
5027 went away many years ago on all practical Emacs targets.
5028 * data.c, image.c, lread.c, print.c:
5029 Don't include <math.h>; no longer needed.
5030 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5031 might be autoconfigured, as that never happens.
5033 * doprnt.c (DBL_MAX_10_EXP):
5034 * print.c (DBL_DIG):
5035 Remove. C89 or later always defines these.
5036 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5037 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5038 (arith_error, domain_error, domain_error2):
5039 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5040 no longer needed -- we simply return what C returns. All uses removed.
5041 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5043 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5044 Remove. All uses expanded, as these macros are no longer used
5045 more than once and are now more trouble than they're worth.
5046 (Ftan): Use tan, not sin / cos.
5047 (Flogb): Assume C89 frexp.
5048 (fmod_float): Assume C89 fmod.
5049 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5050 (init_floatfns): Remove. All uses removed.
5052 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5054 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5055 compositeToPoint for OSX < 10.6 (Bug#12390).
5057 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5059 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5060 This produces more-accurate results.
5062 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5064 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5065 changes (Bug#12088).
5067 2012-09-08 Chong Yidong <cyd@gnu.org>
5069 * syntax.c (Fstring_to_syntax): Doc fix.
5071 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5073 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5074 in the internal border.
5075 (x_set_window_size): Remove static variables and their usage.
5076 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5077 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5078 Remove fringe/internal border adjustment (Bug#11052).
5079 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5080 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5081 (ns_fix_rect_ibw): Remove.
5082 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5083 (ns_dumpglyphs_box_or_relief): Ditto.
5084 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5086 (ns_dumpglyphs_image): Ditto.
5087 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5089 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5090 their usage. Add fringe_extended_p and its use as in other terms.
5091 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5092 scroll bar was removed.
5093 (updateFrameSize): New function.
5094 (windowDidResize): Move code to updateFrameSize and call it.
5096 * nsterm.h (EmacsView): Add updateFrameSize.
5098 2012-09-07 Chong Yidong <cyd@gnu.org>
5100 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5102 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5104 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5106 More signal-handler cleanup (Bug#12327).
5107 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5108 Problem introduced when merging patches. Noted by Eli Zaretskii in
5109 <http://bugs.gnu.org/12327#67>.
5110 * floatfns.c: Comment fix.
5111 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5112 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5113 and anyway the declaration is harmless even if SIGDANGER is not defined.
5114 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5115 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5116 source files not surprisingly expected syssignal.h to define, or
5117 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5118 Include <sys/ioctl.h>, for FIONREAD.
5119 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5120 This eliminates a problem whereby other files mysteriously had
5121 to include "syssignal.h" before including "systty.h" if they
5122 wanted to use "#ifdef SIGIO".
5124 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5126 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5128 * w32.c (sigemptyset): Empty the set.
5129 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5131 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5133 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5135 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5136 (mark_object): Likewise for frame objects.
5138 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5140 * syssignal.h (handle_on_main_thread): Always declare,
5141 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5142 This ports to platforms without HAVE_PTHREAD.
5144 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5146 Signal-handler cleanup (Bug#12327).
5147 Emacs's signal handlers were written in the old 4.2BSD style with
5148 sigblock and sigmask and so forth, and this led to some
5149 inefficiencies and confusion. Rewrite these to use
5150 pthread_sigmask etc. without copying signal sets around. Also,
5151 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5152 'signal', and instead use functions that do not attempt to take
5153 over the system name space. This patch causes Emacs's text
5154 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5155 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5156 Do not include <signal.h> or "syssignal.h", as these
5157 modules do not use signals.
5158 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5159 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5160 Do not include <signal.h>, as "syssignal.h" does that for us now.
5161 * atimer.c (sigmask_atimers): New function.
5162 (block_atimers, unblock_atimers): New functions,
5163 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5165 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5166 no longer needed here.
5167 * emacs.c (main): Inspect existing signal handler with sigaction,
5168 so that there's no need to block and unblock SIGHUP.
5169 * sysdep.c (struct save_signal): New member 'action', replacing
5170 old member 'handler'.
5171 (save_signal_handlers, restore_signal_handlers):
5172 Use sigaction instead of 'signal' to save and restore.
5173 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5174 New function. All users of 'signal' modified to use set_sighandler
5175 if they're writeonly, and to use sys_signal if they're read+write.
5176 (emacs_sigaction_init, forwarded_signal): New functions.
5177 (sys_signal): Remove. All uses replaced by calls to sigaction
5178 and emacs_sigaction_init, or by direct calls to 'signal'.
5179 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5180 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5181 all uses replaced by pthread_sigmask etc. calls.
5182 * syssignal.h: Include <signal.h>.
5183 (emacs_sigaction_init, forwarded_signal): New decls.
5184 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5185 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5186 (sigmask, sys_sigmask): Remove; no longer needed.
5187 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5188 (sigblock, sigunblock, sigfree):
5189 (sigsetmask) [!defined sigsetmask]:
5190 Remove. All uses replaced by pthread_sigmask.
5191 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5192 no longer need to be replaced, and its typical old uses
5193 are now done via emacs_sigaction_init and sigaction.
5194 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5195 (sys_sigdel): Remove; unused.
5196 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5198 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5200 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5201 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5203 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5205 Explicitly mark buffer_defaults and buffer_local_symbols.
5206 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5207 mark_local_symbols here.
5208 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5209 since special buffers aren't marked here any more.
5210 (allocate_buffer): Chain new buffer with all_buffers here...
5211 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5213 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5214 (syms_of_buffer): Remove staticpro of the above.
5215 (init_buffer_once): Set names for buffer_defaults and
5216 buffer_local_symbols.
5218 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5220 Use bool for booleans in font-related modules.
5221 * font.c (font_intern_prop, font_style_to_value)
5222 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5223 (generate_otf_features, font_check_otf_features, font_check_otf)
5224 (font_match_p, font_list_entities, font_at):
5225 * fontset.c (fontset_id_valid_p, reorder_font_vector
5226 (fontset_find_font, Fset_fontset_font)
5227 (face_suitable_for_char_p) [0]:
5228 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5229 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5230 (m17n_flt_initialized, ftfont_shape_by_flt):
5231 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5232 * nsfont.m (nsfont_draw):
5233 * w32font.c (w32font_draw):
5234 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5235 Use bool for booleans.
5236 * font.h: Adjust to above API changes.
5237 (struct font, struct font_driver, struct font_driver_list):
5238 Use bool for booleans.
5239 (struct font): Remove useless member encoding_type.
5241 * fontset.c, xftfont.c: Omit unnecessary static decls.
5243 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5245 * alloc.c (mark_object): Revert window marking code
5246 since it's unsafe for the Fset_window_configuration.
5248 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5250 Fix race conditions with signal handlers and errno (Bug#12327).
5251 Be more systematic about preserving errno whenever a signal
5252 handler returns, even if it's not in the main thread. Do this by
5253 renaming signal handlers to distinguish between signal delivery
5254 and signal handling. All uses changed.
5255 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5256 * data.c (deliver_arith_signal): Rename from arith_error.
5257 * dispnew.c (deliver_window_change_signal): Rename from
5258 window_change_signal.
5259 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5260 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5261 * keyboard.c (deliver_input_available_signal): Rename from
5262 input_available_signal.
5263 (deliver_user_signal): Rename from handle_user_signal.
5264 (deliver_interrupt_signal): Rename from interrupt_signal.
5265 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5266 (deliver_child_signal): Rename from sigchld_handler.
5267 * atimer.c (handle_alarm_signal):
5268 * data.c (handle_arith_signal):
5269 * dispnew.c (handle_window_change_signal):
5270 * emacs.c (handle_fatal_signal, handle_danger_signal):
5271 * keyboard.c (handle_input_available_signal):
5272 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5273 * process.c (handle_pipe_signal, handle_child_signal):
5274 New functions, with the actual signal-handling code taken from the
5275 original respective signal handlers, sans the sporadic attempts to
5276 preserve errno, since that's now done by handle_on_main_thread.
5277 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5278 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5279 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5281 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5282 Move initialization of main_thread to sysdep.c's init_signals.
5283 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5284 our usage, and simplifies the mainline code.
5285 (record_child_status_change): New static function, as a helper
5286 for handle_child_signal, and with most of the old child handler's
5288 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5289 (handle_child_signal): Use the above.
5290 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5291 Moved here from emacs.c.
5292 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5293 code moved here from emacs.c's main function.
5294 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5295 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5296 This lets callers save and restore errno properly.
5298 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5300 Remove redundant or unused things here and there.
5301 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5302 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5303 * editfns.c (Fcompare_buffer_substrings): Likewise.
5304 * frame.h (struct terminal, struct font_driver_list):
5305 Remove redundant declarations.
5306 * window.h (Qleft, Qright): Likewise.
5308 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5310 Do not mark objects from deleted buffers, windows and frames.
5311 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5312 (mark_object): Likewise for windows and frames.
5314 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5316 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5317 buffer_defaults and buffer_local_symbols as valid objects.
5318 Return special value to denote them.
5320 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5322 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5323 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5324 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5325 (file_name_absolute_p, Fsubstitute_in_file_name):
5326 (check_executable, check_writable, Ffile_accessible_directory_p)
5327 (Fset_file_selinux_context, Fdefault_file_modes)
5328 (Finsert_file_contents, choose_write_coding_system)
5329 (Fwrite_region, build_annotations, a_write, e_write)
5331 * filelock.c (boot_time_initialized, get_boot_time)
5332 (get_boot_time_1, lock_file_1, within_one_second):
5333 * floatfns.c (in_float):
5334 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5335 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5336 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5337 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5338 * window.c (compare_window_configurations):
5339 Use bool for booleans.
5340 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5341 (Fdefault_file_modes): Now mode_t, not int, for modes.
5342 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5343 (internal_delete_file): Now returns void, not a (boolean) int,
5344 since nobody was looking at the return value.
5345 * lisp.h, window.h: Adjust to above API changes.
5347 * xdisp.c (set_message): Simplify and reindent last change.
5349 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5351 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5353 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5355 * eval.c (call_debugger): Make the function non-static so that we
5356 can call it from set_message.
5358 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5359 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5361 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5363 Give more-useful info on a fatal error (Bug#12328).
5364 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5365 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5366 of doing the work ourselves.
5367 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5368 do most of the work.
5369 (fatal_error_backtrace): New function, taken from the guts
5370 of the old fatal_error_signal, but with a new option to output
5372 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5373 info about the signal than just its number.
5374 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5375 * sysdep.c: Include <execinfo.h>
5376 (emacs_backtrace): New function, taken partly from the previous
5377 code of the 'die' function.
5378 (emacs_abort): Call fatal_error_backtrace rather than abort.
5380 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5382 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5383 eager (load-time) macro-expansion.
5384 * lisp.mk (lisp): Add macroexp.
5386 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5388 Simplify redefinition of 'abort' (Bug#12316).
5389 Do not try to redefine the 'abort' function. Instead, redo
5390 the code so that it calls 'emacs_abort' rather than 'abort'.
5391 This removes the need for the NO_ABORT configure-time macro
5392 and makes it easier to change the abort code to do a backtrace.
5393 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5394 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5395 Remove; sysdep.c's emacs_abort now takes its place.
5396 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5397 'abort' changed to use 'emacs_abort'.
5398 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5399 (abort) [!defined abort]: Rename to ...
5400 (emacs_abort): ... new name.
5401 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5402 the place of the old 'abort' in emacs.c.
5403 * w32.c, w32fns.c (abort): Do not #undef.
5404 * w32.c (emacs_abort): Rename from w32_abort.
5406 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5408 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5409 offsets[j].dv, since the y axis of the screen coordinates points
5410 down, while the y axis of the font definition coordinates points
5411 up. This fixes display of Arabic diacritics such as KASRA and
5412 KASRATAN. (Bug#11860)
5414 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5416 Be more systematic about _setjmp vs setjmp.
5417 * alloc.c (test_setjmp, mark_stack):
5418 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5419 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5420 (png_load, my_error_exit, jpeg_load):
5421 * process.c (send_process_trap, send_process):
5422 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5423 The underscored versions are up to 30x faster on some hosts.
5424 Formerly, the code used setjmp+longjmp sometimes and
5425 _setjmp+_longjmp at other times, with no particular reason to
5426 prefer setjmp+longjmp.
5428 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5430 Fix minor problem found by static checking.
5431 * buffer.c (Fdelete_all_overlays): Return nil.
5433 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5435 * buffer.c (Fdelete_all_overlays): New function.
5437 2012-09-03 Chong Yidong <cyd@gnu.org>
5439 * gtkutil.c: Add extern decl for Qxft.
5441 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5443 * emacs.c, eval.c: Use bool for boolean.
5444 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5445 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5446 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5447 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5448 (main, decode_env_path, Fdaemon_initialized):
5449 * eval.c (call_debugger, Finteractive_p, interactive_p):
5450 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5451 (maybe_call_debugger, Fbacktrace):
5452 * process.c (read_process_output, exec_sentinel):
5453 Use bool for booleans.
5454 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5455 All callers changed.
5456 * eval.c (interactive_p): Omit always-true boolean argument
5457 EXCLUDE_SUBRS_P. All callers changed.
5458 * dispextern.h, lisp.h: Reflect above API changes.
5459 * firstfile.c (dummy): Use the address of 'main', whose signature
5460 won't change, instead of the address of 'initialize', whose
5461 signature just changed from int to bool.
5462 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5463 * msdos.c (fatal_error_in_progress): ... from here.
5464 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5466 (redisplay_internal, unwind_redisplay): Simply clear
5467 REDISPLAYING_P when unwinding, instead of saving its previous,
5468 always-false value and then restoring it.
5470 Clean up some extern decls.
5471 Mostly, this hoists extern decls out of .c files and into .h files.
5472 That way, we're more likely to catch errors if the interfaces change.
5473 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5474 declare xg_mark_data.
5475 * dispextern.h (x_frame_parm_handlers):
5477 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5478 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

5927 because when IDX has side effects the behavior of IDX==IDX
5928 is undefined. See Stefan Monnier in
5929 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5931 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5933 * lisp.h (functionp): New function (extracted from Ffunctionp).
5934 (FUNCTIONP): Use it.
5935 * eval.c (Ffunctionp): Use it.
5937 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5939 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5940 as that's faster and simpler than static storage. Don't bother
5941 with the g_main_context_query overhead if g_main_context_pending
5942 says no events are pending.
5943 (gfds, gfds_size): Remove these static vars.
5944 (xgselect_initialize): Remove; no longer needed.
5945 All uses and decls removed.
5947 * emacs.c (fatal_error_signal_hook): Remove.
5948 All uses removed. This leftover from old code was always 0.
5950 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5951 * casefiddle.c (casify_object, casify_region):
5952 * casetab.c (set_case_table):
5953 * category.c, category.h (word_boundary_p):
5954 * category.h (CHAR_HAS_CATEGORY):
5955 Use bool for booleans, instead of int.
5957 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5959 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5961 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5963 On assertion failure, print backtrace if available.
5964 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5965 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5966 * Makefile.in (LIB_EXECINFO): New macro.
5969 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5970 * bytecode.c (exec_byte_code):
5971 * callint.c (check_mark, Fcall_interactively):
5972 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5973 (getenv_internal, sync_process_alive, call_process_exited):
5974 * lisp.h (USE_SAFE_ALLOCA):
5975 Use bool for booleans, instead of int.
5976 * lisp.h, process.h: Adjust prototypes to match above changes.
5977 * callint.c (Fcall_interactively): Don't assume the mark's
5978 offset fits in 'int'.
5980 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5982 * buffer.c, buffer.h: Use bool for boolean.
5983 * buffer.c (reset_buffer_local_variables)
5984 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5985 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5986 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5987 (overlay_touches_p, overlay_strings, Foverlay_put)
5988 (report_overlay_modification, call_overlay_mod_hooks):
5989 (mmap_enlarge, mmap_set_vars):
5990 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5991 Use bool for booleans, instead of int.
5992 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5993 since the 1-or-0 return value is always ignored anyway.
5994 (mmap_initialized_p):
5995 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5996 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5998 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6000 * bidi.c: Use bool for boolean.
6001 This is a bit more readable, and makes the text segment of bidi.o
6002 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6003 Presumably it's faster too.
6004 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6006 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6007 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6008 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6009 (bidi_explicit_dir_char, bidi_level_of_next_char)
6010 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6011 Use bool for booleans, instead of int.
6012 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6013 (bidi_unshelve_cache): Adjust decls to match code.
6015 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6017 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6020 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6022 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6023 * atimer.h: Include <stdbool.h>.
6025 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6027 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6028 compile time tests instead of run time tests on systems that do
6030 (FRAME_MAC_P): Remove leftover from deleted code.
6031 * frame.c (syms_of_frame): Remove leftover from deleted code.
6033 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6035 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6037 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6039 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6040 Otherwise, the compiler complains about (A?B:C) where B is void
6041 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6042 (fontset_add): Return void, for FONTSET_ADD.
6044 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6046 * alloc.c: Use bool for booleans.
6047 (gc_in_progress, abort_on_gc)
6048 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6049 (dont_register_blocks) [GC_MALLOC_CHECK]:
6050 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6051 (check_string_bytes, make_specified_string, memory_full)
6052 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6053 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6054 (mark_stack, valid_pointer_p, make_pure_string)
6055 (Fgarbage_collect, survives_gc_p, gc_sweep):
6056 Use bool for booleans, instead of int.
6057 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6058 Remove unused local.
6059 * alloc.c (PURE_POINTER_P):
6060 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6061 * editfns.c (Fformat):
6062 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6064 * fns.c (sweep_weak_table):
6065 * lisp.h (suppress_checking, push_message, survives_gc_p)
6066 (make_pure_string, gc_in_progress, abort_on_gc):
6067 * lread.c (readchar, read1):
6068 * print.c (Fprin1_to_string):
6069 * xdisp.c (push_message):
6070 Use bool for booleans affected directly or indirectly by
6073 Make recently-introduced setters macros.
6074 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6075 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6076 (set_fontset_default, set_fontset_fallback): Rename from their
6077 upper-case counterparts, and make them functions rather than macros.
6078 This is more consistent with the other recently-introduced setters.
6079 These don't need to be inline, since they're local.
6081 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6083 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6084 the loop (Bug#12247).
6086 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6088 * lisp.h (vcopy): Use memcpy rather than our own loop.
6089 This fixes a performance regression introduced by the recent
6090 addition of vcopy. This means 'vcopy' will need to be modified
6091 for a copying collector, but that's OK. Also, tighten the
6092 checking in the assertion.
6094 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6096 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6097 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6098 non-base glyph for the width of the base character, according to
6099 what x_draw_composite_glyph_string_foreground expects.
6100 Generate WADJUST value according to composition_gstring_width's
6101 expectations, to produce correct width of the composed character.
6102 Reverse the sign of the DU offset produced by ScriptPlace.
6104 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6106 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6108 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6110 Avoid direct writes to contents member of struct Lisp_Vector.
6111 * lisp.h (vcopy): New function to copy data into vector.
6112 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6113 * fns.c (Ffillarray): Use ASET.
6114 * keyboard.c (timer_check_2): Use AREF and ASET.
6115 (append_tool_bar_item, Frecent_keys): Use vcopy.
6116 * lread.c (read_vector): Use ASET.
6117 * msdos.c (Frecent_doskeys): Use vcopy.
6118 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6119 (Finternal_merge_in_global_face): Use ASET and vcopy.

6125 the position of its buffer's point.
6126 (Fset_window_point): For the selected window always go in its
6127 buffer to the specified position.
6129 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6131 Setter macros for fontsets.
6132 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6133 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6134 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6137 2012-08-20 Glenn Morris <rgm@gnu.org>
6139 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6140 Don't assume that `ln -f' works.
6142 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6144 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6145 and later about non-assignments with no effect. See discussion at
6146 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6149 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6151 Inline setter functions for Lisp_Objects slots of struct specbinding.
6152 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6155 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6157 * window.c (select_window): Always make selected window's buffer
6160 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6162 Use AREF and ASET for docstrings of category tables.
6163 * category.h (CATEGORY_DOCSTRING): Use AREF.
6164 (SET_CATEGORY_DOCSTRING): Use ASET.
6165 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6167 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6169 Inline setter functions for hash table members.
6170 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6171 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6172 (set_hash_key_and_value, set_hash_index, set_hash_next)
6173 (set_hash_hash): New functions.
6174 * charset.c, fns.c: Adjust users.
6176 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6178 Inline getter and setter functions for per-buffer values.
6179 * buffer.h (per_buffer_default, set_per_buffer_default)
6180 (per_buffer_value, set_per_buffer_value): New functions.
6181 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6182 * buffer.c, data.c: Adjust users.
6184 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6186 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6188 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6190 Rely on <config.h> + <unistd.h> to declare 'environ',
6191 as gnulib does this if the system doesn't.
6192 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6193 Remove declaration. MS-Windows declares it on stdlib.h which is
6194 included by conf_post.h.
6195 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6196 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6197 * vm-limit.c: Include <unistd.h>, for 'environ'.
6199 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6200 (start_of_data): Remove decl; mem-limits.h provides it.
6202 * xdisp.c (handle_invisible_prop): Make it a bit faster
6203 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6205 2012-08-19 Chong Yidong <cyd@gnu.org>
6207 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6210 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6212 * .gdbinit: Use call instead of set when calling a function in the
6215 * data.c (set_internal): Don't use set_blv_found.
6216 (Fkill_local_variable): Likewise.
6218 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6220 * nsfont.m (ns_ascii_average_width): Ensure the string
6221 ascii_printable is initialized with a null-terminated character
6222 array. Otherwise, it can contain undesired extra characters.
6224 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6226 port new setting code to Sun C 5.8 2005/10/13
6227 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6228 Return void, not Lisp_Object. Otherwise, the compiler
6229 complains about (A?B:C) where B is void and C is Lisp_Object
6230 when compiling CHAR_TABLE_SET, due to the recent change to
6231 the API of sub_char_table_set_contents.
6233 2012-08-18 Chong Yidong <cyd@gnu.org>
6235 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6236 for the string case (Bug#3874).
6238 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6240 * buffer.h (BSET): Remove (Bug#12215).

6310 New setter functions.
6312 * termhooks.h (TSET): Remove (Bug#12215).

6317 * terminal.c (TERMHOOKS_INLINE):

6319 are compiled into code.
6320 (tset_param_alist): New setter function.
6322 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
6324 * keyboard.h (KSET): Remove (Bug#12215).

7064 * w32.c (init_environment): Change the default values of many
7065 environment variables in dflt_envvars[] to NULL, to avoid pushing
7066 them into environment when they were not already defined.
7067 Remove the code that deletes site-lisp subdirectories from the default
7068 value of EMACSLOADPATH, as it is no longer needed.
7069 (check_windows_init_file): Now external, not static.
7070 Use Vload_path as is, without adding anything, as this function is now
7071 called when Vload_path is already set up.
7073 * w32.h (check_windows_init_file): Add prototype.
7075 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7119 Remove unnecessary pointer casts.
7120 * alloc.c (record_xmalloc): New function.
7121 * lisp.h (record_xmalloc): New decl.
7122 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7123 more like a function. This is because the pointer cast is not
7124 needed. All uses changed.
7125 * print.c (print_string, print_error_message): Avoid length recalc.
7127 Improve fix for macroexp crash with debugging (Bug#12118).
7128 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7129 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7130 not supposed to be invoked from the garbage collector.

7132 (gc_aset): New function, which is like ASET but can be
7133 used in the garbage collector.

7162 with addition of handling of symlinks and support for 'lstat'.
7163 If possible, get file's attributes and security information by
7164 handle, not by name. Produce S_IFLNK bit for symlinks, when
7165 called from 'lstat'.
7166 (stat, lstat): New functions, call 'stat_worker'.
7167 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7168 symlinks when the underlying filesystem supports them.
7170 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7172 Fix macroexp crash on Windows with debugging (Bug#12118).
7173 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7174 checking subscripts; problem introduced with the recent
7175 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7176 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7177 since it's used in non-static inline functions now.
7179 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7180 Don't assume buffer size fits in 'int'. Remove unused local.

7200 * composite.c (COMPOSITE_INLINE):
7201 * dispnew.c (DISPEXTERN_INLINE):
7202 * sysdep.c (SYSTIME_INLINE):
7203 Define to EXTERN_INLINE, so that the corresponding functions
7204 are compiled into code.
7205 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7206 (INLINE_HEADER_END): New macros.
7207 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7227 hard-coding the path separator.
7229 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7231 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7232 This how ASET and AREF are supposed to work, and makes
7233 it easier to think about future improvements. See
7234 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7235 * charset.h (set_charset_attr): New function.

7704 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7706 Fast save_excursion_save and save_excursion_restore.
7707 * lisp.h (struct Lisp_Excursion): New data type.
7708 (PVEC_EXCURSION): New pseudovector type.
7709 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7710 to deal with it. Adjust comments.

7725 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7726 emacs.c, as this is a more-suitable home. Had this been done earlier
7727 the fix for 12036 would have avoided some of the problems noted in
7728 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7729 would have been more obvious.
7730 * emacs.c: Do not include <verify.h>; no longer needed.
7731 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7732 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7733 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7734 Remove; now done in lisp.h.
7735 * lisp.h (PUBLISH_TO_GDB): New macro.

7739 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7740 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7741 not be usable in #if. This simplifies things.
7743 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7745 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7747 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

7750 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7751 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7752 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7753 Adjust to changes in lisp.h and emacs.c, by using
7754 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7755 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7756 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7757 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7758 instead of gdb_valbits.
7759 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7760 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7761 instead of gdb_array_mark_flag.
7762 (xboolvector): Get size from $->size, not $->header.size.
7763 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7764 (xreload, hook-run, hookpost-run): Remove.
7765 * emacs.c: Include <verify.h>.
7766 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7767 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7769 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7770 (gdb_USE_LSB_TAG): New enum constants.
7771 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7772 Also define these as enum constants, so they're visible to GDB.
7773 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7774 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7775 as constants, so they're visible to GDB.

7777 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
7778 Now enum constants, not macros, so they're visible to GDB.
7779 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7780 more convenient now. All uses changed.
7781 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7782 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7784 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7791 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7792 add argument, tune behavior, and adjust all callers.
7794 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7796 Use typedef for EMACS_INT, EMACS_UINT.
7797 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7798 than macros. This simplifies debugging in the usual case, since
7799 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7800 and it allows expressions involving EMACS_INT casts.
7801 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7803 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7815 Adjust buffer text indirection counters at the end of Fkill_buffer.
7816 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7817 buffer is definitely dead. This should really fix an issue reported
7818 by Christoph Scholtes again. (Bug#12007).
7819 (init_buffer_once): Initialize indirection counters of
7820 buffer_defaults and buffer_local_symbols (for sanity and safety).
7822 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7824 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7825 and continuation glyphs on tooltip frames, leave them at zero.
7826 Avoids continued lines in tooltips. (Bug#11832)
7828 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

7853 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7855 Swap buffer text indirection counters in Fbuffer_swap_text.
7856 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7857 This avoids crash reported by Christoph Scholtes at
7858 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7860 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7862 * nsmenu.m (Popdown_data): New struct.

7885 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7887 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7888 as it's limited by the amount of memory, not by INT_MAX.
7890 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7892 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7893 in special-event-map. See the discussion at

8043 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8045 * eval.c (Fdefvar): Don't check constants since we only set the var if
8046 it's not yet defined anyway (bug#11904).
8048 * lisp.h (last_undo_boundary): Declare new var.
8049 * keyboard.c (command_loop_1): Set it.
8050 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8051 were auto-added by the command loop (bug#11774).

8591 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
8593 Avoid calls to strlen in font processing functions.
8594 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
8595 (font_open_by_name): Change to use length argument.
8596 Adjust users accordingly.
8597 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
8599 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
8600 Change to return ptrdiff_t.
8601 (xfont_list_pattern, xfont_match): Use length returned by
8602 xfont_decode_coding_xlfd.
8603 * xfns.c (x_default_font_parameter): Omit useless xstrdup.

8613 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
8615 Remove "#define unix" that is no longer needed (Bug#11905).
8616 * s/aix4-2.h (unix): Remove; no longer needed.
8618 EMACS_TIME simplification (Bug#11875).
8619 This replaces macros (which typically do not work in GDB)
8620 with functions, typedefs and enums, making the code easier to debug.
8621 The functional style also makes code easier to read and maintain.
8622 * systime.h: Include <sys/time.h> on all hosts, not just if
8623 WINDOWSNT, since 'struct timeval' is needed in general.
8624 (EMACS_TIME): Now a typedef, not a macro.
8625 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8627 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
8628 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
8629 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
8630 (EMACS_TIME_LE): Now functions, not macros.
8631 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
8632 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8633 which are not functions. All uses rewritten to use:
8634 (make_emacs_time): New function.
8635 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8636 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8637 not functions. All uses rewritten to use the following, respectively:
8638 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8639 (add_emacs_time, sub_emacs_time): New functions.
8640 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8641 * fileio.c (Fcopy_file):
8642 * xterm.c (XTflash): Get the current time closer to when it's used.
8643 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8649 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
8650 * frame.c (Fmake_terminal_frame):
8651 * gtkutil.c (get_utf8_string):
8653 * nsmenu.m (ns_update_menubar):
8654 * regex.c (regerror):
8655 Prefer memcpy to strncpy and strncat when either will do.
8656 * fileio.c (Fsubstitute_in_file_name):
8657 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8658 (menu_separator_name_p):
8659 * nsmenu.m (ns_update_menubar):
8660 Prefer memcmp to strncmp when either will do.
8661 * nsterm.m: Include <ftoastr.h>.
8663 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8664 Prefer snprintf to strncpy.
8665 * nsterm.m (ns_term_init):
8666 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8667 * nsterm.m (ns_term_init):
8668 Avoid the need for strncpy, by using build_string or
8669 make_unibyte_string directly. Use dtoastr, not snprintf.
8670 * process.c (Fmake_network_process): Diagnose service names that
8671 are too long, rather than silently truncating them or creating
8672 non-null-terminated names.
8673 (Fnetwork_interface_info): Likewise, for interface names.
8674 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8675 Prefer sprintf to strncat.
8676 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8677 Prefer vsnprintf to vsprintf + strncpy.
8679 2012-07-10 Glenn Morris <rgm@gnu.org>
8681 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8682 Clarify fallback case.
8684 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8686 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
8687 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8688 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8689 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8690 where argument type is known to be a Lisp_Cons.
8692 2012-07-10 Tom Tromey <tromey@redhat.com>
8694 * bytecode.c (BYTE_CODE_THREADED): New macro.
8695 (BYTE_CODES): New macro. Replaces all old byte-code defines.
8696 (enum byte_code_op): New type.
8697 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
8698 (exec_byte_code): Use them. Use token threading when applicable.
8700 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8702 Optimize pure C strings initialization.
8703 * lisp.h (make_pure_string): Fix prototype.
8704 (build_pure_c_string): New function, defined as static inline. This
8705 provides a better opportunity to optimize away calls to strlen when
8706 the function is called with compile-time constant argument.
8707 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8708 argument, adjust users accordingly. Use build_pure_c_string where
8710 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8711 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8712 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8714 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8716 Avoid calls to strlen in miscellaneous functions.
8717 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8718 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8719 * lread.c (openp): Likewise.
8721 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8723 Avoid calls to strlen in path processing functions.
8724 * fileio.c (file_name_as_directory): Add comment. Change to add
8725 srclen argument and return the length of result. Adjust users
8727 (directory_file_name): Fix comment. Change to add srclen argument,
8728 swap 1st and 2nd arguments to obey the common convention.
8729 Adjust users accordingly.
8730 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8732 2012-07-10 Glenn Morris <rgm@gnu.org>
8734 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
8735 Move PENDING_OUTPUT_COUNT definition to configure.
8737 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
8738 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8739 * s/gnu.h (DATA_START): Move definitions to configure.
8741 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8742 We include usg5-4-common.h, which defines them both.
8744 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8745 O_RDONLY already includes it).
8747 Stop ns builds setting the EMACSLOADPATH environment variable.
8748 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8749 Now it does not set EMACSLOADPATH, just returns the load-path string.
8750 * nsterm.h: Update accordingly.
8751 * lread.c [HAVE_NS]: Include nsterm.h.
8752 (init_lread) [HAVE_NS]: Use ns_load_path.
8753 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8755 2012-07-09 Glenn Morris <rgm@gnu.org>
8757 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8758 since the included bsd-common.h does so.
8760 Stop ns builds setting the EMACSPATH environment variable.
8761 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8762 (ns_init_paths): Do not set EMACSPATH.
8763 * nsterm.h (ns_exec_path): Add it.
8764 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8767 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8769 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8771 * process.c (wait_reading_process_output): 'waitchannels' was unset
8772 when read_kbd || !NILP (wait_for_cell); fix this.
8774 Add GCC-style 'const' attribute to functions that can use it.
8775 * character.h (char_resolve_modifier_mask):
8776 * keyboard.h (make_ctrl_char):
8777 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8778 (init_character_once, next_almost_prime, init_fns, init_image)
8779 (flush_pending_output, init_sound):
8780 * mem-limits.h (start_of_data):
8781 * menu.h (finish_menu_items):
8782 Add ATTRIBUTE_CONST.

8784 Declare the dummy function with ATTRIBUTE_CONST.
8785 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8786 Add decls with ATTRIBUTE_CONST.
8788 Minor improvements to make_formatted_string.
8789 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8790 where int is good enough, as vsprintf returns an int.
8791 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8793 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8795 Use make_formatted_string to avoid double length calculation.
8796 * lisp.h (make_formatted_string): New prototype.
8797 * alloc.c (make_formatted_string): New function.
8798 * buffer.c (Fgenerate_new_buffer_name): Use it.
8799 * dbusbind.c (syms_of_dbusbind): Likewise.

8802 * frame.c (make_terminal_frame, set_term_frame_name)
8803 (x_report_frame_params): Likewise.
8804 * image.c (gs_load): Likewise.
8805 * minibuf.c (get_minibuffer): Likewise.
8806 * msdos.c (dos_set_window_size): Likewise.
8807 * process.c (make_process): Likewise.

8820 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8822 Move marker debugging code under MARKER_DEBUG.
8823 * marker.c (MARKER_DEBUG): Move marker debugging code under
8824 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8825 for bootstrap with --enable-checking (~3x slowdown reported
8826 by Juanma Barranquero <lekktu@gmail.com>).
8827 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8829 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8831 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8832 See <http://bugs.gnu.org/11825#29>.
8834 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8836 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8837 has no font, use the frame's font. (Bug#11813)
8838 (display_line): Add commentary about displaying truncation glyphs
8840 (produce_special_glyphs): Move here from term.c.
8842 * term.c (produce_special_glyphs): Move to xdisp.c.
8844 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8847 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8849 * xdisp.c (display_line): Avoid warning about implicit declaration
8852 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8854 * lisp.h: Remove empty conditional.
8856 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8858 * lread.c (load_path_check): Now static.
8860 Fix some minor --with-ns problems found by static checking.
8861 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8862 (x_set_font) [!HAVE_X_WINDOWS]:
8863 * image.c (xpm_load_image) [HAVE_NS]:
8864 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8865 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8866 Remove unused local.
8867 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8868 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8869 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8870 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8871 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8872 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8873 Fix pointer signedness problem.
8874 * xfaces.c (FRAME_X_FONT_TABLE):
8875 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8877 2012-07-07 Glenn Morris <rgm@gnu.org>
8879 * lread.c (load_path_check): New function, split from init_lread.
8880 (init_lread): Reorganize. Motivation:
8881 If EMACSLOADPATH is set, check/warn about that rather than the
8882 defaults, which we are not going to use. Hence we can remove
8883 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8884 Don't warn if site-lisp directories are missing.
8885 If not installed, start from a blank load-path, since
8886 PATH_LOADSEARCH refers to the eventual installation directories.
8888 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8890 Support truncation and continuation glyphs on GUI frames, when
8891 fringes are disabled. (Bug#11832)
8892 * xdisp.c (init_iterator): Get dimensions of truncation and
8893 continuation glyphs even if on GUI frames.
8894 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8895 or both, are absent.
8896 (start_display, move_it_in_display_line_to): Handle the case of a
8897 GUI frame without a fringe to display continuation or truncation
8899 (insert_left_trunc_glyphs): Support GUI frames: make sure
8900 truncation glyphs overwrite enough glyphs from the current line to
8901 have sufficient space in pixels.
8902 (display_line): Support truncation and continuation glyphs on GUI
8903 frames. If some spare pixels are left on the line after inserting
8904 the truncation glyphs, fill that space with a stretch glyph of a
8905 suitably computed width.
8907 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8908 produce_glyphs, to support GUI sessions.
8910 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8912 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8914 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8916 Do not require float-time's arg to fit in time_t (Bug#11825).
8917 This works better on hosts where time_t is unsigned, and where
8918 float-time is applied to the (negative) difference between two times.
8919 * editfns.c (decode_time_components): Last arg is now double *,
8920 not int *, and means to store all the result as a double, without
8921 worrying about whether the seconds part fits in time_t.
8922 All callers changed.
8923 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8924 All callers changed.
8925 (Ffloat_time): Do not fail merely because the specified time falls
8926 outside of time_t range.
8928 2012-07-07 Glenn Morris <rgm@gnu.org>

8934 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
8936 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8937 Update dependencies.
8939 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8941 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8943 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
8944 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
8945 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8946 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8947 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8948 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8950 * xfont.c (compare_font_names): Redo to omit the need for casts.
8952 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8954 * xfns.c (Fx_change_window_property): Doc fix.
8955 * w32fns.c (Fx_change_window_property): Doc fix.
8957 * w32fns.c (Fx_window_property): Accept the same arguments as the
8958 X Windows version. Doc fix.
8959 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8961 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8962 Eli Zaretskii <eliz@gnu.org>
8964 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8965 Windows-specific code from nt/config.nt moved here.
8966 Obsolete settings removed.
8968 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8970 * process.c: Avoid unnecessary calls to gettime.
8971 (wait_reading_process_output): Don't get the time of day
8972 when gobbling data immediately and not waiting, as there's no need
8973 for it in that case. This removes a FIXME.
8975 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8977 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8978 is defined (Bug#11768).
8980 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8986 Call byte_char_debug_check with correct arguments.
8988 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8990 Compile marker debugging code only if ENABLE_CHECKING is defined.
8991 * marker.c (byte_char_debug_check, count_markers):
8992 Use only if ENABLE_CHECKING is defined.
8993 (byte_debug_flag): Remove.
8994 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8995 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8997 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8999 Avoid code repetition in marker-related functions.
9000 * marker.c (attach_marker): New function.

9025 * window.c (save_window_save): Likewise.
9027 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9029 Do not use Fdelete_overlay in delete_all_overlays
9030 to avoid redundant calls to unchain_overlay.
9031 * buffer.c (drop_overlay): New function.
9032 (delete_all_overlays, Fdelete_overlay): Use it.
9033 * minibuf.c (get_minibuffer): Fix comment.
9035 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9037 Port to OpenBSD 5.1 amd64.
9038 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9039 This is needed for OpenBSD, and should be harmless on all BSD systems.
9040 Also, include <sys/sysctl.h>, as it should be available on all
9041 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9042 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9043 use p_pid member, not kp_proc.pid.
9045 2012-07-06 Glenn Morris <rgm@gnu.org>
9047 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9049 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9051 More xmalloc and related cleanup.
9052 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9059 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9060 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9062 Omit needless casts involving void * pointers and allocation.
9063 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9064 as the former is more robust if P's type is changed.
9065 Prefer xzalloc to xmalloc + memset 0.
9066 Simplify malloc-or-realloc to realloc.
9067 Don't worry about xmalloc returning a null pointer.
9068 Prefer xstrdup to xmalloc + strcpy.
9069 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9071 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9072 alloca of a constant.
9074 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9076 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9077 hscroll is larger than the line width. Fixes long and futile
9078 looping inside extend_face_to_end_of_line (on a TTY) producing
9079 glyphs that are not needed and thrown away.
9081 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9083 * marker.c (set_marker_restricted_both): Simplify by using
9086 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9088 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9090 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
9092 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
9093 not defined (Bug#11768).
9094 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9095 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9096 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9097 followed by gtk_box_set_homogeneous (Bug#11768).
9098 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9099 (update_theme_scrollbar_width, xg_create_scroll_bar):
9100 Use gtk_scrollbar_new (Bug#11768).
9101 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9102 (is_box_type): New function (Bug#11768).
9103 (xg_tool_item_stale_p): Call is_box_type.
9104 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9105 with default display (Bug#11768).
9107 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9109 * xdisp.c (window_hscroll_limited): New function.
9110 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9111 coordinates when window's hscroll is set to insanely large
9114 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9116 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9117 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
9119 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9122 * lisp.h (xzalloc): New prototype. Omit needless casts.
9123 * alloc.c (xzalloc): New function. Omit needless casts.

9177 * fileio.c (time_error_value): Check the right error number.
9178 Problem reported by Troels Nielsen in
9179 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9181 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9183 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9184 This should be fixed in a better way; see Eli Zaretskii in
9185 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9186 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9188 * fileio.c (time_error_value): Rename from special_mtime.
9189 The old name's problems were noted by Eli Zaretskii in
9190 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9192 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9193 This variable's comment says Emacs needs at least one GDB-visible
9194 symbol of type enum pvec_type, to work around GDB problems.
9195 The symbol's value doesn't matter.
9197 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9198 that causes compilation to fail on pre-C99 compilers.
9200 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9202 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9203 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9205 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9207 * buffer.c (init_buffer_once): Fix initialization of
9208 headers for buffer_defaults and buffer_local_symbols.
9209 Reported by Juanma Barranquero <lekktu@gmail.com>.
9211 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9213 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9214 * lisp.h (enum pvec_type): Use fewer bits.
9215 (PSEUDOVECTOR_SIZE_BITS): New constant.
9216 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9217 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9218 change in pvec_type.
9219 (PSEUDOVECTOR_TYPEP): New macro.
9220 (TYPED_PSEUDOVECTORP): Use it.
9221 * fns.c (internal_equal): Adapt code to extract pvectype.
9222 * emacs.c (gdb_pvec_type): Update type.
9223 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9224 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9225 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9226 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9227 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9228 abusing vector->header.next.nbytes.
9229 (live_vector_p): Use PVEC_TYPE.
9230 (mark_object): Adapt code to extract pvectype. Use switch.
9232 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9234 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9235 Tighten new eassert a bit.
9237 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9239 Fix compilation with --enable-gcc-warnings and -O1
9241 * doprnt.c (doprnt): Change type of tem to int, initialize
9242 to avoid compiler warning. Add eassert.
9243 * search.c (simple_search): Initialize match_byte to avoid
9244 compiler warning. Add eassert.
9246 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9248 Avoid weird behavior with large horizontal scrolls.
9249 Without this change, for example, large hscroll values would
9250 mess up Emacs's display on Fedora 15 x86, presumably due to
9251 overflows in int calculations in the display code.
9252 Also, if buffers had long lines, Emacs would freeze.
9253 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9254 (set_window_hscroll): New function, containing the old guts of
9255 Fset_window_hscroll. Return the clipped value.
9256 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9257 This avoids the need to check against PTRDIFF_MAX.
9259 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9261 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9263 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9265 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9267 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9268 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9269 since GCC 4.4.6 issues a bogus warning for them.
9271 Fix bugs in file timestamp newness comparisons.
9272 * fileio.c (Ffile_newer_than_file_p):
9273 * lread.c (Fload): Use full timestamp resolution of files,
9274 not just the 1-second resolution, so that files that are only
9275 slightly newer still count as newer.
9276 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9277 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9279 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9281 * fileio.c: Improve handling of file time marker. (Bug#11852)
9282 (special_mtime): New function.
9283 (Finsert_file_contents, Fverify_visited_file_modtime):
9284 Use it to set special mtime values consistently.
9286 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9288 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9289 marker for non-existing file. (Bug#11852)
9291 2012-07-03 Glenn Morris <rgm@gnu.org>
9293 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9294 and did not make it into globals.h).
9296 2012-07-03 Tom Tromey <tromey@redhat.com>
9298 * window.c (Fset_window_margins, Fset_window_fringes)
9299 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9300 * textprop.c (Fprevious_property_change): No longer static.
9301 * syntax.c (Fsyntax_table_p): No longer static.
9302 * process.c (Fget_process, Fprocess_datagram_address): No longer

9317 * composite.c (Fcomposition_get_gstring): No longer static.
9318 * callproc.c (Fgetenv_internal): No longer static.
9320 * ccl.h: Remove EXFUNs.

9322 * dispextern.h: Remove EXFUNs.
9323 * intervals.h: Remove EXFUNs.
9324 * fontset.h: Remove EXFUN.
9325 * font.h: Remove EXFUNs.
9326 * dosfns.c (system_process_attributes): Remove EXFUN.
9327 * keymap.h: Remove EXFUNs.
9328 * lisp.h: Remove EXFUNs.
9329 * w32term.h: Remove EXFUNs.
9330 * window.h: Remove EXFUNs.
9331 * xsettings.h: Remove EXFUN.
9332 * xterm.h: Remove EXFUN.
9334 2012-07-03 Glenn Morris <rgm@gnu.org>
9336 * lisp.h (Frandom): Make it visible to C.
9337 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9338 buffer for invisible buffers. (Bug#1229)
9340 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9342 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9343 values which aren't power of 2.
9344 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9345 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9348 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9350 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9352 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9354 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9356 * alloc.c (allocate_vector_block): Remove redundant
9357 calls to mallopt if DOUG_LEA_MALLOC is defined.
9358 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9359 avoid calls to mallopt if zero_vector is returned.
9361 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9363 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9364 is enabled, avoid dereferencing NULL current_sblock if
9367 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9369 Cleanup basic buffer management.
9370 * buffer.h (struct buffer): Change layout to use generic vector
9371 marking code. Fix some comments. Change type of 'clip_changed'
9372 to bitfield. Remove unused #ifndef old.
9373 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9374 (GET_OVERLAYS_AT): Fix indentation.
9375 (for_each_per_buffer_object_at): New macro.
9376 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
9377 (Fbuffer_local_variables): Use it.
9378 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9379 * alloc.c (allocate_buffer): Adjust to match new layout of
9380 struct buffer. Fix comment.
9381 (mark_overlay): New function.
9382 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9383 Lisp area of struct buffer.
9384 (mark_object): Use it. Adjust marking of misc objects
9385 and related comments.
9387 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9389 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9390 wrapper that is not needed because the wrapped code is a no-op (zero
9391 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9392 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9394 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9396 * alloc.c (mark_buffer): Simplify. Remove prototype.
9397 (mark_object): Add comment. Reorganize marking of vector-like
9398 objects. Use CHECK_LIVE for all vector-like objects except buffers
9399 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9400 Avoid redundant calls to mark_vectorlike for bool vectors.
9402 2012-06-30 Glenn Morris <rgm@gnu.org>
9404 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9406 * epaths.in (PATH_SITELOADSEARCH): New.
9407 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9408 This is rather than relying on --enable-locallisppath elements
9409 having "site-lisp" in their names. (Bug#10208#25, 11658)
9411 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9413 * w32proc.c (sys_select): Accept and ignore one more argument.
9415 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9417 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9418 (pselect) [!MS_DOS]: Redirect to sys_select.
9420 * sysdep.c: Don't include dos.h and dosfns.h.
9422 * process.c (sys_select):
9423 * msdos.c (sys_select): Accept one more argument and ignore it.
9425 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9426 adapt data types and code to that.
9429 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9430 which clashes with the gnulib function of the same name.
9432 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9434 * font.c (font_style_to_value, font_style_symbolic)
9435 (font_prop_validate_style): Add type checks for values in
9438 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9440 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9443 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9445 * xdisp.c (try_window_id): Undo last change.
9447 * w32.c (getwd): Adjust commentary about startup_dir.
9448 (init_environment): Always call sys_access, even in non-MSVC
9449 builds. Don't chdir to the directory of the Emacs executable.
9450 This undoes code from 1997 which was justified by the need to
9451 "avoid conflicts when removing and renaming directories". But its
9452 downside was that every relative file name was being interpreted
9453 relative to the directory of the Emacs executable, which can never
9454 be TRT. In particular, it broke sys_access when called with
9455 relative file names.
9456 (sys_access): Map GetLastError to errno.
9458 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9460 * window.h (struct window): Change type of 'fringes_outside_margins'
9461 to bitfield. Fix comment. Adjust users accordingly.
9462 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9464 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9467 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9469 * gnutls.c (emacs_gnutls_handshake):
9470 Add QUIT to make the loop interruptible.
9472 2012-06-29 Glenn Morris <rgm@gnu.org>
9474 * charset.c (init_charset): Make lack of etc/charsets fatal.
9476 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9478 * editfns.c (region_limit): Fix type mismatch.
9480 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9482 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9483 undefined. Convert from xassert to eassert.
9484 * nsmenu.m: Convert from xassert to eassert.
9485 * nsterm.m: Likewise.
9487 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9489 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9491 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9493 Avoid integer overflow on scroll-left and scroll-right.
9494 * window.c (HSCROLL_MAX): New macro.
9495 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9496 overflow when requested scroll falls outside ptrdiff_t range.
9498 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9500 * window.h (struct window): Change type of 'hscroll',
9501 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9502 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9503 Adjust users accordingly.
9504 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9505 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'

9650 Use sprintf return value instead of invoking strlen on result.
9651 In the old days this wasn't portable, since some sprintf
9652 implementations returned char *. But they died out years ago and
9653 Emacs already assumes sprintf returns int.
9654 Similarly for float_to_string.
9655 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

9663 Use sprintf or float_to_string result to avoid need to call strlen.
9664 * data.c (Fnumber_to_string):
9665 Use make_unibyte_string, since the string must be ASCII.
9666 * lisp.h, print.c (float_to_string): Now returns int length.
9667 * term.c (produce_glyphless_glyph):
9668 Use sprintf result rather than recomputing it.
9670 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9671 * Makefile.in (ALL_CFLAGS):
9672 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

9701 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9703 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

9706 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9708 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9709 instead of truncating it to 63 (admittedly a generous limit).

9764 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9766 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

9768 * dispnew.c (Fsleep_for, sit_for):
9769 * keyboard.c (kbd_buffer_get_event):
9770 * process.c (Faccept_process_output):
9771 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9772 This improves on the previous patch, which introduced a bug
9773 when time_t is unsigned and as wide as intmax_t.
9774 See <http://bugs.gnu.org/9000#51>.
9776 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9778 * dispnew.c (sit_for, Fsleep_for):

9793 Privately reported by Herbert J. Skuhra.
9794 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

9797 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9799 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9801 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9802 last argument of make_unibyte_string.
9804 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9805 language ID in the event parameters.
9807 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9808 event.code, not the obscure "character set ID".

9831 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9832 Privately reported by Herbert J. Skuhra.

9839 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9841 Support higher-resolution time stamps (Bug#9000).
9842 The time stamps are only nanosecond-resolution at the C level,
9843 since that's the best that any real-world system supports now.
9844 But they are picosecond-resolution at the Lisp level, as that's
9845 easy, and leaves room for future OS improvements.
9847 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9850 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9851 Don't get current time unless it's needed.
9853 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9854 now provides it if it's absent.
9855 (start_atimer): Port to higher-res time stamps.
9856 Check for time stamp overflow. Don't get current time more
9857 often than is needed.
9859 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9860 Include systime.h, not time.h.
9861 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9863 * dired.c: Include stat-time.h.
9864 (Ffile-attributes): File times now have higher resolution.

9867 (struct image): Timestamp now has higher resolution.
9869 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9870 has at least microseconds now. All uses removed.
9871 (update_frame, update_single_window, update_window, update_frame_1)
9872 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9873 (duration_to_sec_usec): Remove; no longer needed.
9875 * editfns.c (time_overflow): Now extern.
9876 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9877 (float-time, Fformat_time_string, Fcurrent_time_string)

9881 (decode_time_components, lisp_seconds_argument): New functions.
9882 (make_time): Now static.
9883 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9884 Report an error if the time is invalid, rather than having the caller
9887 * fileio.c: Include <stat-time.h>
9888 (Fcopy_file): Copy higher-resolution time stamps.
9889 Prefer to set the time stamp via a file descriptor if that works.
9890 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9891 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9892 (Fvisited_file_modtime, Fset_visited_file_modtime):
9893 Support higher-resolution time stamps.
9895 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9897 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9899 * image.c (prepare_image_for_display, clear_image_cache)
9900 (lookup_image): Port to higer-resolution time stamps.
9902 * keyboard.c (start_polling, bind_polling_period):
9903 Check for time stamp overflow.
9904 (read_char, kbd_buffer_get_event, timer_start_idle)
9905 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9906 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9907 Port to higher-resolution time stamps. Do not assume time_t is signed.
9908 (decode_timer): New function. Timers are now vectors of length 9,
9909 not 8, to accommodate the picosecond component.
9910 (timer_check_2): Use it.
9912 * nsterm.m (select_timeout, timeval_subtract): Remove.
9913 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9914 as they're a bit more accurate and handle overflow better.
9915 (ns_select): Change prototype to be compatible with pselect.
9916 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9917 * nsterm.h (ns_select): Adjust prototype.
9919 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9920 us-resolution time stamps.
9921 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9923 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9925 * lisp.h (time_overflow): New decl.
9926 (wait_reading_process_output): First arg is now intmax_t, not int,
9927 to accommodate larger waits.
9929 * process.h (struct Lisp_Process.read_output_delay):
9930 Now counts nanoseconds, not microseconds.
9931 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9933 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9934 (wait_reading_process_output):
9935 Port to ns-resolution time stamps.
9936 (Faccept_process_output, wait_reading_process_output):
9937 Check for time stamp overflow. Do not assume time_t is signed.
9938 (select_wrapper): Remove; we now use pselect.
9939 (Fprocess_attributes): Now generates ns-resolution time stamps.
9941 * sysdep.c: Include utimens.h. Don't include utime.h
9942 or worry about struct utimbuf; gnulib does that for us now.
9943 (gettimeofday): Remove; gnulib provides a substitute.
9944 (make_timeval): New function.
9945 (set_file_times): Now sets ns-resolution time stamps.
9946 New arg FD; all uses changed.
9947 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9948 (system_process_attributes):
9949 Now returns ns-resolution time stamp. All uses changed.
9950 Check for time stamp overflow.
9952 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9953 provides a substitute now.
9955 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9956 since it guarantees struct timespec.
9957 (EMACS_TIME): Now struct timespec, so that we can support
9958 ns-resolution time stamps.
9959 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9960 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9961 (EMACS_USECS): Remove.
9962 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9963 so multiply the arg by 1000 before storing it.
9964 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9966 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9967 Port to ns-resolution time stamps.
9968 (EMACS_TIME_NEG_P): Remove; replaced by....
9969 (EMACS_TIME_SIGN): New macro.
9970 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9971 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9972 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9973 (make_timeval, make_lisp_time, decode_time_components): New decls.
9974 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9975 that it mishandled time_t overflow. You can't compare by subtracting!
9976 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9977 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9979 * term.c: Include <sys/time.h>.
9980 (timeval_to_Time): New function, for proper overflow wraparound.
9981 (term_mouse_position, term_mouse_click): Use it.
9983 * undo.c (record_first_change): Support higher-resolution time stamps
9985 (Fprimitive_undo): Use them when restoring time stamps.
9987 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9988 (w32_get_internal_run_time):
9989 Port to higher-resolution Emacs time stamps.

10436 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10438 * doprnt.c (doprnt): Truncate multibyte char correctly.
10439 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10440 would mishandle a string argument "Xc" if X was a multibyte
10441 character of length 2: it would truncate after X's first byte
10442 rather than including all of X.
10444 2012-06-06 Chong Yidong <cyd@gnu.org>
10446 * buffer.c (word_wrap): Doc fix.
10448 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
10450 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.
10452 2012-06-03 Glenn Morris <rgm@gnu.org>
10454 * xdisp.c (tool-bar-style): Doc fix.
10456 2012-06-03 Ulrich Müller <ulm@gentoo.org>
10458 * Makefile.in (PAXCTL): Define.
10459 (temacs$(EXEEXT)): Disable memory randomization for the temacs
10460 binary via PaX flags if the paxctl utility is available.
10461 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
10462 Restore PaX flags to their default. (Bug#11398)
10464 2012-06-03 Chong Yidong <cyd@gnu.org>
10466 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
10467 buffer (Bug#11226).
10469 2012-06-03 Chong Yidong <cyd@gnu.org>
10471 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
10472 (note_mode_line_or_margin_highlight): If there is no help echo,
10473 use mode-line-default-help-echo. Handle the case where the mouse
10474 position is past the end of the mode line string.
10476 * buffer.c (buffer_local_value_1): New function, split from
10477 Fbuffer_local_value; can return Qunbound.
10478 (Fbuffer_local_value): Use it.
10479 (Vmode_line_format): Docstring tweaks.
10481 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
10483 * sysdep.c (system_process_attributes): Improve comment.
10485 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
10487 * keyboard.c: Export real-this-command to Elisp.
10488 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
10489 and DEFVAR it. Update all users.
10491 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
10493 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10495 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10496 Convert pctcpu and pctmem to Lisp float properly.
10497 Let the compiler fold better, as 100.0/0x8000 is exact.
10499 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10501 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10504 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
10506 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
10508 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10510 For a 'struct window', replace some Lisp_Object fields to
10511 bitfields where appropriate, remove unused fields.
10512 * window.h (struct window): Remove unused 'last_mark_x' and
10513 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10514 change its type from Lisp_Object to bitfield.
10515 Change type of 'force_start', 'optional_new_start',
10516 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10517 fields from Lisp_Object to bitfield. Adjust users accordingly.
10519 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10521 Pacify gcc -Wdouble-precision when using Xaw.
10522 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10523 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10524 Use 'float' consistently, rather than 'float' in most places
10525 and 'double' in a couple of places.
10527 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10529 * xdisp.c (handle_stop): Detect whether we have overlay strings
10530 loaded by testing it->current.overlay_string_index to be
10531 non-negative, instead of checking whether n_overlay_strings is
10532 positive. (Bug#11587)
10534 2012-05-31 Chong Yidong <cyd@gnu.org>
10536 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10538 * doc.c (Fsubstitute_command_keys): Doc fix.
10540 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10542 * search.c (search_buffer): Remove calls to
10543 r_alloc_inhibit_buffer_relocation, as it is now called by
10544 maybe_unify_char, which was the cause of relocation of buffer text
10547 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10549 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10550 for the duration of call to load_charset, to avoid problems with
10551 callers of maybe_unify_char that access buffer text through C
10554 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10555 decrement the inhibition flag, instead of just setting or
10558 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10560 Remove obsolete '#define static' cruft.
10561 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10562 This #undef was "temporary" in 2000; it is no longer needed
10563 now that '#define static' has gone away.
10564 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10565 (gray_bitmap_bits): Remove; no longer needed.
10566 All uses replaced with definiens.
10567 * xterm.c: Include "bitmaps/gray.xbm".
10569 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10571 Clean up __executable_start, monstartup when --enable-profiling.
10572 The following changes affect the code only when profiling.
10573 * dispnew.c (__executable_start): Rename from safe_bcopy.
10574 Define only on platforms that need it.
10575 * emacs.c: Include <sys/gmon.h> when profiling.
10576 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10577 (__executable_start): Remove decl, since lisp.h does it now.
10578 (safe_bcopy): Remove decl; no longer has that name.
10579 (main): Coalesce #if into single bit of code, for simplicity.
10580 Cast pointers to uintptr_t, since standard libraries want integers
10582 * lisp.h (__executable_start): New decl.
10584 2012-05-31 Glenn Morris <rgm@gnu.org>
10586 * image.c (Fimagemagick_types): Doc fix.
10588 2012-05-30 Jim Meyering <meyering@redhat.com>
10590 * callproc.c (Fcall_process_region): Include directory component
10591 in mkstemp error message (Bug#11586).
10593 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10595 * alloc.c, lisp.h (make_pure_vector): Now static.
10597 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10599 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10600 Move to byte-run.el.

10603 (Qdefun): Move from eval.c.
10604 * lisp.h (Qdefun): Remove.
10605 * lread.c (read1): Tiny simplification.
10607 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10609 Do not create empty overlays with the evaporate property (Bug#9642).
10610 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10611 Bug#9642, but explicitly check that the buffer the overlay would
10612 be moved to is live and rearrange lines to make sure that errors
10613 will not put the overlay in an inconsistent state.
10614 (Fdelete_overlay): Cosmetics.
10616 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10618 * w32term.c (my_bring_window_to_top): New function.
10619 (x_raise_frame): Use handle returned by DeferWindowPos, which
10620 could be different from the original one.
10621 Call my_bring_window_to_top instead of my_set_foreground_window.
10624 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
10625 by calling BringWindowToTop.

10630 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10632 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10633 This avoids undefined behavior that might cause the eassert
10634 to not catch an out-of-range value.
10636 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10638 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10639 Update dependencies.
10641 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10643 * bidi.c (bidi_mirror_char): Fix last change.
10645 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
10647 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
10648 when referring to sectname field in printf format.
10650 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10652 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10653 Only r_alloc_inhibit_buffer_relocation needed to be added;
10654 the others were already declared.
10656 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10657 before checking whether it's out of range. Put the check inside
10659 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10661 2012-05-27 Ken Brown <kbrown@cornell.edu>
10663 * callproc.c (Fcall_process): Restore a line that was accidentally
10664 commented out in the 2011-02-13 change (bug#11547).
10666 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10668 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10669 defined on ralloc.c.
10671 * buffer.c [REL_ALLOC]: Remove prototypes of
10672 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10673 they are now on lisp.h.
10675 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10677 * search.c (search_buffer): Use it to inhibit relocation of buffer
10678 text while re_search_2 is doing its job, because re_search_2 is
10679 passed C pointers to buffer text. (Bug#11519)
10681 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10682 Update value to 24.
10684 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10685 state after an additional call to move_it_in_display_line_to, keep
10686 the values of it->max_ascent and it->max_descent found for the
10688 (pos_visible_p): Revert the comparison against bottom_y to what it
10689 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10692 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10694 Fix coding-related core dumps with gcc -ftrapv.
10695 The code was computing A - B, where A and B are pointers, and B is
10696 random garbage. This can lead to core dumps on platforms that
10697 have special pointer registers, and it also leads to core dumps on
10698 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10699 A - B only when B is initialized properly.
10700 * coding.c (coding_set_source, coding_set_destination): Return void.
10701 (coding_change_source, coding_change_destinations): New functions,
10702 with the old behaviors of coding_set_source and coding_set_destination.
10703 All callers that need an offset changed to use these new functions.
10705 2012-05-26 Glenn Morris <rgm@gnu.org>
10707 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10709 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10711 Extend mouse support on W32 text-mode console.
10712 * xdisp.c (draw_row_with_mouse_face):
10713 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10715 * w32console.c: Include window.h.
10716 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10718 (initialize_w32_display): Initialize mouse-highlight data.
10720 * w32inevt.c: Include termchar.h and window.h.
10721 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10722 moves, call note_mouse_highlight. If help_echo changed, call
10723 gen_help_event to produce help-echo message in the echo area.
10724 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10727 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10729 * lread.c (read1): Simplify slightly to avoid an overflow warning
10730 with GCC 4.7.0 on x86-64.
10732 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10734 * bidi.c (bidi_mirror_char): Revert last change: an int is
10735 definitely wide enough here.
10737 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10739 Fix integer width and related bugs (Bug#9874).
10740 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
10741 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10742 (string_bytes, check_sblock, allocate_string_data):
10743 (compact_small_strings, Fmake_bool_vector, make_string)
10744 (make_unibyte_string, make_multibyte_string)
10745 (make_string_from_bytes, make_specified_string)
10746 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10747 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10749 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10750 (allocate_pseudovector):
10751 Use int, not EMACS_INT, where int is wide enough.
10752 (inhibit_garbage_collection, Fgarbage_collect):
10753 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10754 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10755 int might not be wide enough.
10756 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10757 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10758 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10759 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10760 (bidi_level_of_next_char, bidi_move_to_visually_next):
10761 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10762 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10763 (Fkill_buffer, Fset_buffer_major_mode)
10764 (advance_to_char_boundary, Fbuffer_swap_text)
10765 (Fset_buffer_multibyte, overlays_at, overlays_in)
10766 (overlay_touches_p, struct sortvec, record_overlay_string)
10767 (overlay_strings, recenter_overlay_lists)
10768 (adjust_overlays_for_insert, adjust_overlays_for_delete)
10769 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
10770 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
10771 (Foverlay_recenter, last_overlay_modification_hooks_used)
10772 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10773 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10774 (validate_region): Omit unnecessary test for b <= e,
10775 since that's guaranteed by the previous test.
10776 (adjust_overlays_for_delete): Avoid pos + length overflow.
10777 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10778 (report_overlay_modification):
10779 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10780 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10781 Omit pointer cast, which isn't needed anyway, and doesn't work
10782 after the EMACS_INT -> ptrdiff_t change.
10783 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10784 * buffer.h: Adjust decls to match defn changes elsewhere.
10785 (struct buffer_text, struct buffer):
10786 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10787 Use EMACS_INT, not int, where int might not be wide enough.
10788 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10789 not int, to avoid needless 32-bit limit on 64-bit hosts.
10790 (exec_byte_code): Use tighter memory-full test, one that checks
10791 for alloca overflow. Don't compute the address of the object just
10792 before an array, as that's not portable. Use EMACS_INT, not
10793 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10794 * callint.c (Fcall_interactively):
10795 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10796 * callproc.c (call_process_kill, Fcall_process):
10797 Don't assume pid_t fits into an Emacs fixnum.
10798 (call_process_cleanup, Fcall_process, child_setup):
10799 Don't assume pid_t fits into int.
10800 (call_process_cleanup, Fcall_process, delete_temp_file)
10801 (Fcall_process_region):
10802 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10803 (Fcall_process): Simplify handling of volatile integers.
10804 Use int, not EMACS_INT, where int will do.
10805 * casefiddle.c (casify_object, casify_region, operate_on_word)
10806 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10807 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10808 (casify_object): Avoid integer overflow when overallocating buffer.
10809 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10810 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10811 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10812 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10813 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10814 integers are now checked earlier. All uses replaced with XINT.
10816 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10817 For CCL_MapSingle, check that content and value are in int range.
10818 (ccl_driver, Fregister_code_conversion_map):
10819 Check that Vcode_version_map_vector is a vector.
10820 (resolve_symbol_ccl_program): Check that vector header is in range.
10821 Always copy the vector, so that we can check its contents reliably
10822 now rather than having to recheck each instruction as it's being
10823 executed. Check that vector words fit in 'int'.
10824 (ccl_get_compiled_code, Fregister_ccl_program)
10825 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10826 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10827 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10828 contents are in range.
10829 (Fccl_execute_on_string): Check that status is in range.
10830 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10831 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10832 Accept and return EMACS_INT, not int, because callers can pass values
10833 out of 'int' range.
10834 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10835 (multibyte_chars_in_text, parse_str_as_multibyte)

10837 (str_as_unibyte, str_to_unibyte, string_count_byte8)
10838 (string_escape_byte8, Fget_byte):
10839 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10840 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10841 avoid mishandling large integers.
10842 * character.h: Adjust decls to match defn changes elsewhere.
10843 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10844 (Ffind_charset_region):
10845 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10846 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
10847 (load_charset_map_from_vector, Fdefine_charset_internal):
10848 Don't assume fixnum fits in int.
10849 (load_charset_map_from_vector, Fmap_charset_chars):
10850 Remove now-unnecessary CHECK_NATNUMs.
10851 (Fdefine_charset_internal): Check ranges here, more carefully.
10852 Don't rely on undefined behavior with signed left shift overflow.
10853 Don't assume unsigned int fits into fixnum, or that fixnum fits
10854 into unsigned int. Don't require max_code to be a valid fixnum;
10855 that's not true for gb10830 4-byte on a 32-bit host. Allow

11527 * xterm.c (x_x_to_emacs_modifiers):
11528 Don't assume EMACS_INT overflows nicely into int.
11529 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
11530 may come from Lisp.
11531 (handle_one_xevent): NATNUMP can eval its arg twice.
11532 (x_connection_closed):
11533 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11534 * xterm.h: Adjust decls to match defn changes elsewhere.
11535 (struct scroll_bar): Use struct vectorlike_header
11536 rather than rolling our own approximation.
11537 (SCROLL_BAR_VEC_SIZE): Remove; not used.
11539 2012-05-25 Glenn Morris <rgm@gnu.org>
11541 * lisp.mk (lisp): Update for more files being compiled now.
11543 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11545 * lread.c: Remove `read_pure' which makes no difference.
11546 (read_pure): Remove var.
11547 (unreadpure): Remove function.
11548 (readevalloop): Don't call read_list with -1 flag.
11549 (read1, read_vector): Don't test read_pure any more.
11550 (read_list): Simplify.
11552 * fileio.c, character.h: Minor style tweaks.
11554 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
11556 * window.h (clip_changed): Remove useless declaration.
11558 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
11560 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
11561 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11563 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11566 This directory predates autoconf and is no longer needed nowadays.
11567 Move its few remaining bits of functionality to where they're needed.
11568 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
11569 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
11570 * m/template.h: Remove.
11571 * Makefile.in (M_FILE): Remove. All uses removed.
11572 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11573 * lisp.h (USE_LSB_TAG):
11574 * mem-limits.h (EXCEEDS_LISP_PTR):
11575 Use VAL_MAX, not VALBITS, in #if.
11576 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11577 (EMACS_UINT): Define unconditionally now.
11578 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11579 (BITS_PER_EMACS_INT): New constants, replacing
11580 what used to be in config.h, but not useful in #if.
11581 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11582 define them any more.
11583 (VAL_MAX): New macro.
11585 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11586 BITS_PER_EMACS_INT, in #if.
11587 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11588 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11589 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11590 * s/ms-w32.h (DATA_START):
11591 Move here from removed file m/intel386.h.
11592 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11593 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11595 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11597 Assume C89 or later.
11598 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11599 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11601 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
11602 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
11603 * textprop.c, tparam.c (NULL): Remove.
11604 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
11605 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
11606 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
11607 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11608 * xterm.c (input_signal_count): Assume volatile works.
11610 2012-05-21 Ken Brown <kbrown@cornell.edu>
11612 * xgselect.c (xg_select): Fix first argument in call to 'select'
11615 2012-05-20 Ken Brown <kbrown@cornell.edu>
11617 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11618 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11620 2012-05-19 Ken Brown <kbrown@cornell.edu>
11622 * xfns.c (x_in_use): Remove `static' qualifier.
11623 * xterm.h (x_in_use): Declare.
11624 * xgselect.c: Include xterm.h.
11625 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11626 and `display_arg' (bug#9754).
11628 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11630 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11632 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11633 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11635 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11637 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11639 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11640 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11642 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11643 reference to image_cache->refcount.
11644 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11646 2012-05-17 Juri Linkov <juri@jurta.org>
11648 * search.c (Fword_search_regexp, Fword_search_backward)
11649 (Fword_search_forward, Fword_search_backward_lax)
11650 (Fword_search_forward_lax): Move functions to isearch.el
11651 (bug#10145, bug#11381).
11653 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11655 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11657 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11659 * lread.c (init_obarray): Declare Qt and Qnil as special.
11661 2012-05-14 Glenn Morris <rgm@gnu.org>
11663 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11664 Put "libexec" before "bin", for the sake of init_callproc_1.
11666 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11668 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11670 * unexaix.c: Port to more-recent AIX compilers.
11671 (report_error, report_error_1, make_hdr, copy_sym)
11672 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11673 Make arguments const char *, not char *, to avoid violations of C
11674 standard and to fix some AIX warnings reported by Gilles Pion.
11676 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11678 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11679 already have overlays loaded.
11680 (handle_single_display_spec): Before returning without displaying
11681 fringe bitmap, synchronize the bidi iterator with the main display
11682 iterator, by calling iterate_out_of_display_property.
11683 (iterate_out_of_display_property): Detect buffer iteration by
11684 testing that it->string is a Lisp string.
11685 (get_next_display_element): When the current object is exhausted,
11686 and there's something on it->stack, call set_iterator_to_next to
11687 proceed with what's on the stack, instead of returning zero.
11688 (set_iterator_to_next): If called at the end of a Lisp string,
11689 proceed to consider_string_end without incrementing string
11690 position. Don't increment display vector index past the end of
11691 the display vector. (Bug#11417)
11692 (pos_visible_p): Don't report a position visible when move_it_to
11693 stopped at the last line of window, which happens to be scanned
11694 backwards by the bidi iteration. (Bug#11464)
11696 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11698 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11699 and right-margin display specs even if the spec is invalid or we
11700 are on a TTY, and thus unable to display on the fringes.
11701 That's because the text with the property will not be displayed anyway,
11702 so we need to signal to the caller that this is a "replacing"
11703 display spec. This fixes display when the spec is invalid or we
11706 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11708 * unexaix.c (make_hdr): Fix typo in prototype.
11709 This bug broke the build on AIX. Problem reported by Gilles Pion.
11711 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11713 * keyboard.c (kbd_buffer_get_event): Read special events also in
11714 batch mode. (Bug#11415)
11716 2012-05-12 Glenn Morris <rgm@gnu.org>
11718 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11720 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11722 * lisp.mk (lisp): Add newcomment.elc.
11724 2012-05-12 Glenn Morris <rgm@gnu.org>
11726 * Makefile.in (MKDIR_P): New, set by configure.
11727 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11729 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11731 Remove unused function hourglass_started.
11732 * dispextern.h (hourglass_started):
11733 * w32fns.c (hourglass_started):
11734 * xdisp.c (hourglass_started): Remove.
11736 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11738 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11739 Update dependencies.
11741 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11743 * xgselect.c (xg_select): Put maxfds+1 into a var.
11744 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11746 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11748 2012-05-10 Dave Abrahams <dave@boostpro.com>
11750 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11751 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11753 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11755 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11756 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11757 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11758 Initialize xd_registered_buses.
11760 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11762 Untag more efficiently if USE_LSB_TAG.
11763 This is based on a proposal by YAMAMOTO Mitsuharu in
11764 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11765 For an admittedly artificial (nth 8000 longlist) benchmark on
11766 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11767 Emacs's overall text size by 1%.
11768 * lisp.h (XUNTAG): New macro.
11769 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11770 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11771 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11772 * eval.c (Fautoload):
11773 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11774 * frame.h (XFRAME): Use XUNTAG.
11776 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11777 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11778 Remove unportable assumptions about print widths of types like
11780 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11781 intptr_t when converting between pointer and integer, to avoid GCC
11782 warnings about wrong width.
11784 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11786 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11787 stack for each reader_thread, instead of defaulting to 8MB
11788 determined by the linker. This avoids failures in creating
11789 subprocesses on Windows 7, see the discussion in this thread:
11790 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11792 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11794 Fix up display of the *Minibuf-0* buffer in the mini window.
11795 * keyboard.c (read_char): Don't clear the echo area if there's no
11797 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11798 contents of *Minibuf-0*) if there's no message displayed in its stead.
11800 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11802 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11805 2012-05-06 Chong Yidong <cyd@gnu.org>
11807 * lisp.mk (lisp): Update.
11809 2012-05-05 Jim Meyering <meyering@redhat.com>
11811 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11813 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11815 * data.c (PUT_ERROR): New macro.
11816 (syms_of_data): Use it. Add new error type `user-error'.
11817 * undo.c (user_error): New function.
11818 (Fprimitive_undo): Use it.
11819 * print.c (print_error_message): Adjust print style for `user-error'.
11820 * keyboard.c (user_error): New function.
11821 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11823 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11825 Do not limit current-time-string to years 1000..9999.
11826 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11827 (Fcurrent_time_string): Support any year that is supported by the
11828 underlying localtime representation. Don't use asctime, as it
11829 has undefined behavior for years outside the range -999..9999.
11831 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11833 Fix race conditions involving setenv, gmtime, localtime, asctime.
11834 Without this fix, interrupts could mess up code that uses these
11835 nonreentrant functions, since setting TZ invalidates existing
11836 tm_zone or tzname values, and since most of these functions return
11837 pointers to static storage.
11838 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11839 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11840 Grow the critical sections to include not just invoking
11841 localtime/gmtime, but also accessing these functions' results
11842 including their tm_zone values if any, and any related TZ setting.
11843 (format_time_string): Last arg is now struct tm *, not struct tm **,
11844 so that the struct tm is saved in the critical section.
11845 All callers changed. Simplify allocation of initial buffer, partly
11846 motivated by the fact that memory allocation needs to be outside
11847 the critical section.
11849 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11851 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11852 with RESET_INTERVAL.
11854 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11855 Remove duplicated buffer name initialization.
11857 2012-05-02 Jim Meyering <jim@meyering.net>
11859 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11861 * xfns.c (x_window): Use xstrdup (Bug#11375).
11863 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11865 * xdisp.c (pos_visible_p): If already at a newline from the
11866 display string before the 'while' loop, don't walk back the glyphs
11867 from it3.glyph_row. Solves assertion violation when the display
11868 string begins with a newline (egg.el). (Bug#11367)
11870 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11872 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11875 2012-05-01 Glenn Morris <rgm@gnu.org>
11877 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11878 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11879 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11880 All were removed before 23.1.
11882 * dispnew.c: Remove HAVE_LIBNCURSES test;
11883 it is always true on relevant platforms.
11885 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11886 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11888 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11890 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11892 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11893 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11896 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11898 Do not avoid creating empty evaporating overlays (Bug#9642).
11899 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11900 That is, do not delete an evaporating overlay if it becomes
11901 empty after its bounds are adjusted to fit within its buffer.
11902 This fix caused other problems, and I'm reverting it until we get
11903 to the bottom of them.
11905 2012-04-27 Chong Yidong <cyd@gnu.org>
11907 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11909 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11911 * xdisp.c (pos_visible_p): If the window start position is beyond
11912 ZV, start the display from buffer beginning. Prevents assertion
11913 violation in init_iterator when the minibuffer window is scrolled
11914 via the scroll bar.
11916 * window.c (window_scroll_pixel_based): Likewise.
11918 2012-04-27 Chong Yidong <cyd@gnu.org>
11920 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11922 2012-04-27 Glenn Morris <rgm@gnu.org>
11924 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11925 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11927 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11929 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11930 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11932 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11934 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11935 display element, check also the underlying string or buffer
11936 character. (Bug#11341)
11938 * w32menu.c: Include w32heap.h.
11939 (add_menu_item): If the call to AppendMenuW (via
11940 unicode_append_menu) fails, disable Unicode menus only if we are
11941 running on Windows 9X/Me.
11943 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11945 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11946 (xgetint): Add missing shift for LSB tags.
11948 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11950 * keyboard.c (read_char): Don't wipe echo area for select window
11951 events: These might get delayed via `mouse-autoselect-window'
11954 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11956 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11957 manipulation of :loaded-from data.
11959 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11961 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11962 now a cons (bug#11311).
11964 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11966 Do not create empty overlays with the evaporate property (Bug#9642).
11967 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11968 if it becomes empty after its bounds are adjusted to fit within
11969 its buffer. Without this fix, in a nonempty buffer (let ((o
11970 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11971 yields an empty overlay that has the evaporate property, which is

12176 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12177 (NEED_MEM_INSERT): New macro.
12178 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12179 Remove one incorrect comment and fix another.

12215 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12216 * s/netbsd.h, s/sol2-6.h:
12217 Remove definition of GC_MARK_STACK, since the default now works.
12218 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

12246 2012-04-11 Daniel Colascione <dancol@dancol.org>
12248 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12249 against is gone. It's better to use vfork now so that when Cygwin
12250 gains a new, working vfork, we use it automatically (bug#10398).
12252 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12305 * minibuf.c (Fread_variable): Callers changed.
12307 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12309 * xdisp.c (set_cursor_from_row): If the display string appears in
12310 the buffer at position that is closer to point than the position
12311 after the display string, display the cursor on the first glyph of
12312 the display string. Fixes cursor display when a 'display' text
12313 property immediately follows invisible text. (Bug#11094)
12315 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12317 composite.c: use 'double' consistently
12318 * composite.c (get_composition_id): Use 'double' consistently
12319 instead of converting 'float' to 'double' and vice versa; this is
12320 easier to understand and avoids a GCC warning.
12322 2012-04-09 Glenn Morris <rgm@gnu.org>
12324 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12325 preparation for dumping it with emacs. (Bug#4789)

12374 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12376 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12377 Call init_libxml2_functions before calling libxml2 functions.

12389 point, use it.vpos to compute how many lines to backtrack after
12390 move_it_to point. (Bug#11133)
12392 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12394 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12395 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12396 about subtle differences between FETCH_CHAR* and STRING_CHAR*

12399 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12401 2012-04-04 Chong Yidong <cyd@gnu.org>
12403 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12405 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12407 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12408 instead of alloca. (Bug#11138)
12410 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12412 * w32menu.c (is_simple_dialog): Properly check lisp types.
12415 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12417 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12418 position we get to after a call to move_it_to fails the
12419 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12420 only if we wind up in a string from display property. (Bug#11063)
12422 * window.c (Fdelete_other_windows_internal): Invalidate the row
12423 and column information about mouse highlight, so that redisplay
12424 restores it after reallocating the glyph matrices. (Bug#7464)
12426 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12427 string comes from a `display' text property, use the buffer
12428 position of that property as if we actually saw that position in
12430 (move_it_by_lines): Remove the assertion that
12431 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12432 violated when there's a before-string at the beginning of a line.
12435 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12437 * xdisp.c (append_space_for_newline): If the default face was
12438 remapped, use the remapped face for the appended newline.
12439 (extend_face_to_end_of_line): Use the remapped default face for
12440 extending the face to the end of the line.
12441 (display_line): Call extend_face_to_end_of_line when the default
12442 face was remapped. (Bug#11068)
12444 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12446 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12448 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12450 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12452 2012-03-27 Glenn Morris <rgm@gnu.org>
12454 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12457 2012-03-26 Kenichi Handa <handa@m17n.org>
12459 * dispextern.h (struct glyph): Fix previous change. Change the
12460 bit length of glyphless.ch to 25 (Bug#11082).
12462 2012-03-26 Chong Yidong <cyd@gnu.org>
12464 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12465 (command_loop_1): Use it; inhibit selection update for
12466 handle-select-window too (Bug#8996).
12468 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12470 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12472 2012-03-25 Kenichi Handa <handa@m17n.org>
12474 * dispextern.h (struct glyph): Change the bit length of
12475 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12477 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12479 * s/ms-w32.h (tzname): Include time.h before redirecting to
12480 _tzname. Fixes the MSVC build. (Bug#9960)
12482 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12484 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12487 * xterm.c (XTread_socket): Only modify handling_signal if
12488 !SYNC_INPUT. (Bug#11080)
12490 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12492 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12493 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12494 when fetching a multibyte character consumes more bytes than
12495 CHAR_BYTES returns, due to unification of CJK characters in
12496 string_char. (Bug#11073)
12498 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12500 * process.c (wait_reading_process_output): Handle pty disconnect
12501 by refraining from sending oneself a SIGCHLD (bug#10933).
12503 2012-03-22 Chong Yidong <cyd@gnu.org>

12507 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12508 Mark string as coming from a prefix property.
12509 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12510 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12512 2012-03-21 Chong Yidong <cyd@gnu.org>
12514 * xfaces.c (Vface_remapping_alist): Doc fix.
12516 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12518 * w32proc.c (Fw32_set_console_codepage)

12524 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12525 to reflect default non-nil value of redisplay-dont-pause.
12527 2012-03-19 Kenichi Handa <handa@m17n.org>
12529 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12530 it fit in a valid range (Bug#11003).
12532 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12534 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12535 that is not from display property, accept the row as a "cursor
12536 row" if one of the string's character has a non-nil `cursor'
12537 property. Fixes cursor positioning when there are newlines in
12538 overlay strings, e.g. in icomplete.el. (Bug#11035)
12540 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12542 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12544 2012-03-12 Chong Yidong <cyd@gnu.org>
12546 * eval.c (inhibit_lisp_code): Rename from
12547 inhibit_window_configuration_change_hook; move from window.c.
12549 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12550 * window.c (run_window_configuration_change_hook)
12551 (syms_of_window): Callers changed.

12566 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
12568 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
12570 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12571 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12574 2012-03-03 Glenn Morris <rgm@gnu.org>
12576 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12578 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12580 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12581 position past the first glyph_row that ends at ZV. (Bug#10902)
12582 (redisplay_window, next_element_from_string): Fix typos in
12584 (redisplay_window): Pass to move_it_vertically the margin in
12585 pixels, not in screen lines.
12587 2012-03-02 Glenn Morris <rgm@gnu.org>
12589 * buffer.c (buffer-list-update-hook): Doc fix.
12591 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12593 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12594 push_it before setting up the iterator for the first overlay
12595 string, even if we have an empty string loaded.
12596 (next_overlay_string): If there's an empty string on the iterator
12597 stack, pop the stack. (Bug#10903)
12599 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12601 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12602 Suggested by Stefan Monnier in
12603 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12604 * alloc.c (widen_to_Lisp_Object): New static function.
12605 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12606 and widening them to Lisp_Objects. This would work even if
12607 USE_LSB_TAG is defined and wide integers are used, which might
12608 happen in a future version of Emacs.
12610 2012-02-25 Chong Yidong <cyd@gnu.org>
12612 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12615 * xselect.c (Fx_selection_exists_p): Doc fix.
12616 (x_clipboard_manager_save_all): Print an informative message
12617 before saving to clipboard manager.
12619 2012-02-24 Chong Yidong <cyd@gnu.org>
12621 * keyboard.c (process_special_events): Handle all X selection
12622 requests in kbd_buffer, not just the next one (Bug#8869).
12624 2012-02-23 Chong Yidong <cyd@gnu.org>
12626 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12627 call when setting menu-bar-lines and tool-bar-lines parameters.
12628 (unwind_create_frame_1): New helper function.
12630 * window.c (inhibit_window_configuration_change_hook): New var.
12631 (run_window_configuration_change_hook): Obey it.
12632 (syms_of_window): Initialize it.
12634 2012-02-22 Chong Yidong <cyd@gnu.org>
12636 * xterm.c (x_draw_image_relief): Add missing type check for
12637 Vtool_bar_button_margin (Bug#10743).
12639 2012-02-21 Chong Yidong <cyd@gnu.org>
12641 * fileio.c (Vfile_name_handler_alist): Doc fix.
12643 * buffer.c (Fget_file_buffer): Protect against invalid file
12644 handler return value.
12646 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
12648 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
12649 when computing $valmask.
12651 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12652 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12653 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12654 It's useless in that case, and it can cause problems on hosts
12655 that allocate halves of EMACS_INT values separately.
12656 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12657 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12658 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12659 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12660 it avoids undefined behavior on hosts where shifting right by more
12661 than the word width has undefined behavior.
12663 2012-02-19 Chong Yidong <cyd@gnu.org>
12665 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12666 (Funhandled_file_name_directory, Ffile_name_as_directory)
12667 (Fdirectory_file_name, Fexpand_file_name)
12668 (Fsubstitute_in_file_name): Protect against invalid file handler
12669 return values (Bug#10845).
12671 2012-02-18 Eli Zaretskii <eliz@gnu.org>
12673 * .gdbinit (pitx): Fix incorrect references to fields of the
12676 2012-02-17 Chong Yidong <cyd@gnu.org>
12678 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
12680 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
12682 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
12683 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12685 2012-02-15 Chong Yidong <cyd@gnu.org>
12687 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12688 marked as special. Also, starting docstrings with * is obsolete.
12690 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
12692 * gnutls.c (emacs_gnutls_write): Fix last change.
12694 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
12696 * gnutls.c (emacs_gnutls_write): Set errno appropriately for

12701 * keymap.c (Fsingle_key_description): Handle char ranges.
12703 2012-02-12 Chong Yidong <cyd@gnu.org>
12705 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12706 as that creates a dangerous corner case.
12708 * window.c (Fdelete_window_internal): Invalidate the mouse
12709 highlight (Bug#9904).
12711 2012-02-12 Glenn Morris <rgm@gnu.org>
12713 * xselect.c (Fx_own_selection_internal)
12714 (Fx_get_selection_internal, Fx_disown_selection_internal)
12715 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12716 * nsselect.m (Fx_own_selection_internal)
12717 (Fx_disown_selection_internal, Fx_selection_exists_p)
12718 (Fx_selection_owner_p, Fx_get_selection_internal):
12719 Sync docs and argument specs with the xselect.c versions.
12721 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12723 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
12725 2012-02-11 Eli Zaretskii <eliz@gnu.org>
12727 * w32select.c (Fx_selection_exists_p): Sync doc string and
12728 argument list with xselect.c. (Bug#10783)
12730 * w16select.c (Fx_selection_exists_p): Sync doc string and
12731 argument list with xselect.c. (Bug#10783)
12733 2012-02-10 Glenn Morris <rgm@gnu.org>
12735 * fns.c (Fsecure_hash): Doc fix.
12737 2012-02-09 Kenichi Handa <handa@m17n.org>
12739 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
12741 2012-02-07 Chong Yidong <cyd@gnu.org>
12743 * buffer.c (Fbuffer_local_variables)
12744 (buffer_lisp_local_variables): Handle unbound vars correctly;
12745 don't let Qunbound leak into Lisp.
12747 2012-02-07 Glenn Morris <rgm@gnu.org>
12749 * image.c (Fimagemagick_types): Doc fix.
12751 * image.c (imagemagick-render-type): Change it from a lisp object
12752 to an integer. Move the doc here from the lisp manual.
12753 Treat all values not equal to 0 the same.
12755 2012-02-06 Chong Yidong <cyd@gnu.org>
12757 * doc.c (store_function_docstring): Avoid applying docstring of

12769 2012-02-04 Eli Zaretskii <eliz@gnu.org>
12771 * w32.c (get_emacs_configuration_options):
12772 Include --enable-checking, if specified, in the return value.
12774 2012-02-04 Martin Rudalics <rudalics@gmx.at>
12776 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
12777 after rounding frame sizes. (Bug#9723)
12779 2012-02-04 Eli Zaretskii <eliz@gnu.org>
12781 * keyboard.c (adjust_point_for_property): Don't position point
12782 before BEGV. (Bug#10696)
12784 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12786 Handle overflow when computing char display width (Bug#9496).
12787 * character.c (char_width): Return EMACS_INT, not int.
12788 (char_width, c_string_width): Check for overflow when
12789 computing the width; this is possible now that individual
12790 characters can have unbounded width. Problem introduced
12791 by merge from Emacs 23 on 2012-01-19.
12793 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
12795 * dbusbind.c (Fdbus_register_method): Mention the return value
12796 :ignore in the docstring.
12798 2012-02-02 Glenn Morris <rgm@gnu.org>
12800 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
12802 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
12803 Unconditionally set to t. (Bug#10673)

12808 2012-02-02 Kenichi Handa <handa@m17n.org>
12810 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
12811 0, do not call append_composite_glyph.
12813 2012-02-02 Kenichi Handa <handa@m17n.org>
12815 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12817 (x_produce_glyphs): If the component of a composition is a null
12818 string, set it->pixel_width to 1 to avoid zero-width glyph.
12820 2012-02-01 Eli Zaretskii <eliz@gnu.org>
12822 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12823 first 2 arguments are identical. This makes inserting large
12824 output from a subprocess an order of magnitude faster on
12825 MS-Windows, where all sbrk'ed memory is always contiguous.
12827 2012-01-31 Glenn Morris <rgm@gnu.org>
12829 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

12865 2012-01-21 Chong Yidong <cyd@gnu.org>
12867 * floatfns.c (Fcopysign): Make the second argument non-optional,
12868 since nil is not allowed anyway.
12870 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
12872 * process.c (read_process_output): Use p instead of XPROCESS (proc).
12873 (send_process): Likewise.
12875 2012-01-19 Martin Rudalics <rudalics@gmx.at>
12877 * window.c (save_window_save, Fcurrent_window_configuration)
12878 (Vwindow_persistent_parameters): Do not use Qstate.
12879 Rewrite doc-strings.
12881 2012-01-19 Kenichi Handa <handa@m17n.org>
12883 * character.c (char_width): New function.
12884 (Fchar_width, c_string_width, lisp_string_width):
12885 Use char_width (Bug#9496).

13443 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13444 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13445 is set, removing the need for VIRT_ADDRESS_VARIES.
13446 (PURE_P): Use a more-efficient implementation that needs just one
13447 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13448 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13449 to 4 (xorl, subq, cmpq, setbe).
13450 * alloc.c (pure): Always extern now, since that's the
13451 VIRT_ADDR_VARIES behavior.

13453 consistency with the new puresize.h.
13454 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13455 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13463 behave as if the cursor position were at the window margin.
13465 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13466 and the cursor position is out of bounds, behave as if the cursor
13467 position were at the window margin. (Bug#10075)
13469 2011-11-18 Chong Yidong <cyd@gnu.org>
13471 * window.c (Fwindow_combination_limit): Make first argument

13493 compute_line_metrics.
13494 (compute_line_metrics): Call row_hash, instead of computing the
13497 * dispnew.c (verify_row_hash): Call row_hash for computing the
13498 hash code of a row, instead of duplicating code from xdisp.c.
13500 * dispextern.h (row_hash): Add prototype.
13502 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

13538 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13540 * xdisp.c (display_line): Move the call to
13541 highlight_trailing_whitespace before the call to
13542 compute_line_metrics, since the latter needs to see the final
13543 faces of all the glyphs to compute ROW's hash value.
13544 Fixes assertion violations in row_equal_p. (Bug#10035)
13546 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13548 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13549 just return (bug#10044).

13553 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13554 with user-defined heap size. Bump the default size of the temacs

13558 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13559 current_matrix and desired_matrix. (Bug#9990)
13560 (verify_row_hash) [XASSERTS]: New function.

13607 Avoid some portability problems by eschewing 'extern inline' functions.
13608 The trivial performance wins aren't worth the portability hassles; see

13677 * xmenu.c (cleanup_widget_value_tree): New function.
13678 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

13685 (window_box_width, window_box_left, window_box_left_offset)
13686 (window_box_right, window_box_right_offset): Declare extern.
13687 Otherwise, these inline functions do not conform to C99 and
13688 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13689 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13690 * intervals.c (adjust_intervals_for_insertion)

13693 (static_offset_intervals): Remove.
13694 (offset_intervals): Rewrite using the old contents of
13695 static_offset_intervals. The old version didn't conform to C99
13696 because an extern inline function contained a reference to an

13816 * window.c (Fwindow_body_size): Mention in the doc string that the
13817 return value is in frame's canonical units. (Bug#9949)
13819 2011-11-03 Eli Zaretskii <eliz@gnu.org>
13821 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
13823 * w32fns.c (unwind_create_frame): If needed, free the glyph
13824 matrices of the partially constructed frame. (Bug#9943)
13825 * xfns.c (unwind_create_frame): Likewise.
13827 2011-11-01 Eli Zaretskii <eliz@gnu.org>
13829 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
13830 Don't stop backward scan on the continuation glyph, even though
13831 its CHARPOS is positive.
13832 (mouse_face_from_buffer_pos, note_mouse_highlight):
13833 Rename cover_string to disp_string.
13835 2011-11-01 Martin Rudalics <rudalics@gmx.at>
13837 * window.c (temp_output_buffer_show): Don't use
13838 Vtemp_buffer_show_specifiers.
13839 (Vtemp_buffer_show_specifiers): Remove unused variable.
13841 2011-10-30 Eli Zaretskii <eliz@gnu.org>
13843 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
13844 past the beginning of the current glyph matrix.
13846 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
13848 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
13849 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
13850 HAVE_GTK3 (Bug#9869).
13852 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
13853 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
13855 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
13857 * xterm.c: Declare x_handle_net_wm_state to return int.
13858 (handle_one_xevent): Check if we are iconified but don't have
13859 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
13860 (get_current_wm_state): Return non-zero if not hidden,
13861 check for _NET_WM_STATE_HIDDEN (Bug#9893).

13866 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
13868 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
13869 so that this new function doesn't get optimized away by a
13870 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
13872 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
13874 * frame.h (MOUSE_HL_INFO): Remove excess parens.
13876 2011-10-29 Eli Zaretskii <eliz@gnu.org>
13878 Fix the `xbytecode' command.
13879 * .gdbinit (xprintbytestr): New command.
13880 (xwhichsymbols): Rename from `which'; all callers changed.
13881 (xbytecode): Print the byte-code string as well.
13883 2011-10-29 Kim Storm <storm@cua.dk>
13885 * alloc.c (which_symbols): New function.
13887 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
13889 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
13892 2011-10-29 Glenn Morris <rgm@gnu.org>
13894 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
13895 Not clear what it was for, and it causes various bugs. (Bug#9839)
13897 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13899 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
13900 possible random value that matches one of those tested as
13901 condition to clear the mouse face.
13903 2011-10-28 Chong Yidong <cyd@gnu.org>
13905 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
13907 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
13909 * window.c (make_window): Initialize phys_cursor_on_p.
13911 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
13913 * lisp.h (struct Lisp_Symbol): Update comments.
13915 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
13917 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
13919 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13921 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13922 <oslsachem@gmail.com> for helping to debug this.
13924 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13925 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13926 (g_b_init_get_glyph_outline_w): New static variables.
13927 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
13928 (GetGlyphOutlineW_Proc): New typedefs.
13929 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
13930 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13932 (w32font_open_internal, compute_metrics):
13933 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13934 instead of calling the "wide" APIs directly.
13936 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13938 * w32.h (syms_of_w32font): Add prototype.
13940 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13942 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13943 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13944 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13945 (Fmove_to_window_line): Doc fix.
13947 2011-10-27 Chong Yidong <cyd@gnu.org>
13949 * process.c (make_process): Set gnutls_state to NULL.
13951 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13952 non-NULL, regardless of GNUTLS_INITSTAGE.
13953 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13954 an error. Set process slots as soon as we allocate them.
13956 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13958 2011-10-27 Chong Yidong <cyd@gnu.org>
13960 * gnutls.c (emacs_gnutls_deinit): New function.
13961 Deallocate credentials structures as well as calling gnutls_deinit.
13962 (Fgnutls_deinit, Fgnutls_boot): Use it.
13964 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13965 (deactivate_process): Call emacs_gnutls_deinit.
13967 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13969 * image.c (x_create_x_image_and_pixmap):
13970 * w32.c (sys_rename, w32_delayed_load):
13971 * w32font.c (fill_in_logfont):
13972 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13974 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13976 * w32fns.c (w32_default_color_map): New function,
13977 extracted from Fw32_default_color_map.
13978 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13980 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13982 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13984 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13986 * keyboard.c (test_undefined): New function (bug#9751).
13987 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13989 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13991 * sysdep.c (init_sys_modes): Fix the check for the controlling
13992 terminal (Bug#6649).
13994 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13996 * dispextern.h (struct bidi_it): New member next_en_type.
13998 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13999 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14000 current character, check also for next_en_type being WEAK_EN.
14001 (bidi_resolve_weak): Don't enter the expensive loop if the current
14002 position is before next_en_pos. Record the bidi type of the first
14003 non-ET, non-BN character we find, in addition to its position.
14004 (bidi_level_of_next_char): Invalidate next_en_type when
14005 next_en_pos is over-stepped.
14007 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14009 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14010 * editfns.c: Rewrite current-time-zone so that it invokes
14011 the equivalent of (format-time-string "%Z") to get the time zone name.
14012 This fixes a bug when the time zone name contains characters that
14013 need converting from the system time locale to Emacs internal format.
14014 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14015 that patch fixed format-time-string to do the conversion, but
14016 I forgot to fix current-time-zone.
14017 (format_time_string): New function, containing most of
14018 what Fformat_time_string used to contain.
14019 (Fformat_time_string): Rewrite in terms of format_time_string.
14020 This doesn't change this function's behavior.
14021 (current-time-zone): Rewrite to use format_time_string.
14022 This fixes the bug reported by Michael Schierl in
14023 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14024 Jason Rumney's 2007-06-07 change worked around this bug, but
14026 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14028 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14030 * xdisp.c (start_display): If the character at POS is displayed
14031 via a display vector, reset IT->current.dpvec_index to zero.
14032 (try_window_reusing_current_matrix): If a line ends in a display
14033 vector or the next line starts in a display vector, continue
14034 redrawing the window even though the character position of
14035 start_row was reached.
14038 2011-10-18 Chong Yidong <cyd@gnu.org>
14040 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14041 with nobreak-char-display too.
14043 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14045 Fix part 3 of bug#9771.
14046 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14047 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14048 non-neutral characters if the current character is a paragraph
14049 separator (a.k.a. Newline). This avoids running the same
14050 expensive loop twice, once when we consume the preceding newline
14051 and the other time when the line actually needs to be displayed.
14052 Avoid the loop when we see neutrals on the base embedding level
14053 following a character whose directionality is the same as the
14054 paragraph's. This avoids running the expensive loop when a line
14055 ends in a long sequence of neutrals, like control characters.
14056 Add assertion against STRONG_AL type. Slightly rearrange code
14057 that determines the type of a neutral given the first non-neutral
14059 (bidi_level_of_next_char): Set next_en_pos to zero when
14060 invalidating its info.
14062 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14064 * xdisp.c (push_display_prop): Determine whether to record string
14065 or buffer position by IT->string, not by IT->method. Allow
14066 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14067 (move_it_vertically_backward): Don't look for character position
14068 immediately after the newline when in a continuation line.
14071 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14073 * window.c (coordinates_in_window): Rewrite and delabelize
14074 vertical border check. (Bug#5357) (Bug#9618)
14076 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14078 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14079 errors in XSetWindowBorder (bug#9310).
14081 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14083 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14084 avoid crash when xmalloc overrun checking is enabled.
14086 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14088 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14089 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14090 cursor motion with <left> and <right> arrow keys.
14092 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14093 some callers set that themselves.
14095 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14097 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14098 display string and the previous row comes from the same string and
14099 is empty. (Bug#9739) (Bug#9738)
14101 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14103 * doc.c (get_doc_string): Encode file name (bug#9735).
14105 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14107 * bidi.c (bidi_level_of_next_char):
14108 * xdisp.c (get_visually_first_element): Remove old incorrect
14109 comments regarding the Unicode Line Separator character.
14111 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14113 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14115 * alloc.c (Fgc_status): Do not access beyond zombies array
14116 boundary if nzombies > MAX_ZOMBIES.
14117 * alloc.c (dump_zombies): Add missing format specifier.
14119 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14121 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14122 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14124 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14125 Some packages use them to denote characters with modifiers.
14127 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14129 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14130 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14131 matching a pp-number. Rename parameter var to var1.
14133 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14135 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14137 2011-10-08 Glenn Morris <rgm@gnu.org>
14139 * callint.c (Fcall_interactively): Give a more explicit error for the
14140 'c' case with a non-character input. (Bug#8479)
14142 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14144 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14146 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14147 lines that are hscrolled on the left.
14149 * dispnew.c (buffer_posn_from_coords): Account for a possible
14150 presence of header-line. (Bug#4426)
14152 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14154 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14155 Don't advertise functionality which we discourage or doesn't work.
14157 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14159 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14160 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14161 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14162 this makes Emacs dump core during garbage collection on rare
14163 occasions. sizeof is obviously inferior to offsetof here, so
14164 stick with offsetof.
14165 (GC_POINTER_ALIGNMENT): New macro.
14166 (mark_memory): Omit 3rd (offset) arg; caller changed.
14167 Don't assume EMACS_INT alignment is the same as pointer alignment.
14169 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14171 * keyboard.c (read_key_sequence_remapped): New var.
14172 (read_key_sequence): Compute remapping in the right buffer.
14173 (command_loop_1): Use read_key_sequence's remapping directly.
14175 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14177 * dired.c (file_name_completion): Don't expand file name.
14178 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14179 before checking file name handler.
14181 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14182 they've been requested explicitly (bug#9591).
14184 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14186 * keymap.c (Fsingle_key_description): Use make_specified_string
14187 instead of build_string to build string from push_key_description.
14190 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14192 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14193 This fixes a Y2038 bug on 64-bit hosts.
14194 * buffer.c (reset_buffer):
14195 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14196 (Fclear_buffer_auto_save_failure):
14197 Use 0, not -1, to represent an unset failure time, since time_t
14198 might not be signed.
14200 Remove dependency on glibc malloc internals.
14201 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14202 Move back here from lisp.h, but with their new implementations.
14203 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14204 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14205 * charset.c (charset_table_init): New static var.
14206 (syms_of_charset): Use it instead of xmalloc. This removes a
14207 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14208 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14209 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14210 Move back to alloc.c.
14211 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14212 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14214 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14216 * nsterm.m (windowDidResize): Call x_set_window_size only when
14217 ns_in_resize is true. Otherwise set pixelwidth/height and
14218 call change_frame_size (Bug#9628).
14220 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14222 Port --enable-checking=all to Fedora 14 x86-64.
14223 * charset.c (syms_of_charset): Also account for glibc malloc's
14224 internal overhead when calculating the initial malloc maximum.
14226 Port --enable-checking=all to Fedora 14 x86.
14227 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14229 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14230 (overrun_check_realloc, overrun_check_free):
14231 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14232 That way, xmalloc returns a properly-aligned pointer even if
14233 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14234 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14235 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14236 into account when calculating the initial malloc maximum.
14237 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14238 Move here from alloc.c, so that charset.c can use it too.
14239 Properly align; the old code wasn't right for common 32-bit hosts
14240 when configured with --enable-checking=all.
14241 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14242 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14244 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14246 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14249 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14251 * xdisp.c (compute_display_string_end): If there's no display
14252 string at CHARPOS, return -1.
14254 * bidi.c (bidi_fetch_char): When compute_display_string_end
14255 returns a negative value, treat the character as a normal

14262 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14264 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14265 newline, reseat the iterator instead of bidi-iterating there one
14266 character at a time. (Bug#9610)
14267 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14268 TO_CHARPOS if the bidi iterator is at base embedding level.
14270 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14272 * lread.c (readevalloop): Use correct code for NBSP.

14275 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14277 * dbusbind.c (Fdbus_register_signal): When service is not
14278 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14280 2011-09-25 Glenn Morris <rgm@gnu.org>
14282 * buffer.c (truncate-lines): Doc fix.
14284 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

14299 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14301 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14302 Default value is now t. Doc fix.
14304 * indent.c (Fvertical_motion): Compute and apply the overshoot
14305 logic when moving up, not only when moving down. Fix the
14306 confusing name and values of the it_overshoot_expected variable;
14307 logic changes accordingly. (Bug#9254) (Bug#9549)
14309 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14310 CHARPOS is covered by a display string which includes newlines.
14311 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14312 is covered by a display string with embedded newlines.
14314 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14316 * dbusbind.c (Fdbus_register_signal): Add match rule to
14317 Vdbus_registered_objects_table. (Bug#9581)
14318 (Fdbus_register_method, Vdbus_registered_objects_table):
14321 2011-09-24 Jim Meyering <meyering@redhat.com>
14323 do not ignore write error for any output size
14324 The previous change was incomplete.
14325 While it makes emacs --batch detect the vast majority of stdout
14326 write failures, errors were still ignored whenever the output size is
14327 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14328 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14329 && echo FAIL: ignored write error
14330 FAIL: ignored write error
14331 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14332 && echo FAIL: ignored write error
14333 FAIL: ignored write error
14334 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14336 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14338 * emacs.c (Fkill_emacs): In noninteractive mode exit
14339 non-successfully if a write error occurred on stdout. (Bug#9574)
14341 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14343 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14346 * dispextern.h (struct it): Update the comment documenting what
14349 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14351 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14352 a display string, extend search for cursor position to end of row.
14353 (find_row_edges): If the row ends in a newline from a display
14354 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14355 Handle the case of a display string with multiple newlines.
14356 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14357 non-empty line. Fixes confusing cursor motion with arrow keys at
14358 the beginning of a line that starts with whitespace.
14360 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14362 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14365 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14367 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14368 boolean (Bug#9154).
14370 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14372 * xdisp.c (display_line): Record maximum and minimum buffer
14373 positions even if no glyphs were produced (e.g., by a zero-width
14374 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14375 buffer positions that will be removed from the glyph row because
14377 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14378 column is beyond frame width: don't subtract 1 "pixel" when
14379 computing width of the stretch.
14380 (reseat_at_next_visible_line_start): Undo the change made on
14381 2011-09-17 that saved paragraph information and restored it after
14382 the call to `reseat'. (Bug#9545)
14384 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14386 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14387 and turn window cursor on if cleared (Bug#9415).
14389 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14391 * search.c (boyer_moore): Take unibyte characters from pattern
14392 literally. (Bug#9458)
14394 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14396 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14398 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14400 Fix minor problem found by static checking.

14402 initialized, to pacify gcc -Wuninitialized.
14404 * fileio.c: Report proper errno when syscall falls.
14405 (Finsert_file_contents): Save and restore errno,
14406 so that report_file_error outputs the correct diagnostic.
14407 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14409 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14411 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14413 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14415 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14416 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14418 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14420 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14421 about the current paragraph and restore it after the call to reseat.
14423 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14424 (bidi_find_paragraph_start): Search back for paragraph beginning
14425 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14426 (bidi_move_to_visually_next): Only trigger paragraph-related
14427 computations when the last character is a newline or at EOB, not
14428 just any NEUTRAL_B. (Bug#9470)
14430 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14431 truncated lines if point is covered by a display string. (Bug#9524)
14433 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14435 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14436 (cons_to_x_long): New function.
14437 (lisp_data_to_selection_data): Use it. Correct the test for
14438 short-versus-long data; it was negated. Break out of vector
14439 loop, for efficiency, when a long datum is discovered.
14441 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14443 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14445 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14447 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14448 GCC PR/17406) by declaring this function with external scope.
14450 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14452 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14453 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14455 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14457 * editfns.c (Fformat): Correctly handle text properties on "%%".

14467 of TAB characters in a composition.
14469 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14471 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14472 This occurs when processing a multibyte format.
14473 Problem reported by Wolfgang Jenker.
14475 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14477 * xdisp.c (try_cursor_movement): Only check for exact match if
14478 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14480 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14482 Remove unused external symbols.
14483 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14484 * xdisp.c (calc_pixel_width_or_height): Now static.
14485 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14486 * indent.c (check_display_width):
14487 * w32term.c: Fix comment to match code.
14488 * xterm.c, xterm.h (x_catching_errors): Remove.
14490 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14492 * xselect.c: Use signed conversions more consistently (Bug#9498).
14493 (selection_data_to_lisp_data): Assume incoming selection data are
14494 signed integers, not unsigned. This is to be consistent with
14495 outgoing selection data, which was modified to use signed integers
14496 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14497 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14498 expects long, not unsigned long.
14500 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14502 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14503 computation of loop end. Reported by Johan Bockgård
14506 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14508 * frame.c (Fother_visible_frames_p): Function deleted.
14510 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14512 * indent.c (compute_motion): Process display vector front to back
14513 rather than the other way around. (Bug#2496)
14515 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14517 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14519 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14521 * minibuf.c (Fread_from_minibuffer): Doc fix.
14523 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14525 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14526 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14528 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14530 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14531 value for non-existent files.
14533 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14535 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14536 set its "size" to -1. This will set the modtime_size field of
14537 the corresponding buffer to -1, which is what
14538 verify-visited-file-modtime expects for files that do not exist.
14541 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14543 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14545 * lisp.h: ... from here. push_key_description is no longer
14546 defined in keyboard.c, so its declaration should not be in
14547 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14548 logically belongs with push_key_description.
14550 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14552 * buffer.h: Include <sys/types.h> instead of <time.h>.
14553 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14554 Problem reported by Herbert J. Skuhra.
14556 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14558 * xml.c (parse_region): Make the parsing work for
14559 non-comment-starting XML files again (bug#9144).
14561 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14563 * image.c (gif_load): Fix calculation of bottom and right corner.
14566 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14568 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14569 redisplay in small windows.
14571 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14573 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14575 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14577 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14578 Operate on live windows only.
14580 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14582 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14584 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14586 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14587 only under bidi iteration.
14589 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14591 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14593 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14595 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14596 Without this fix, the command to link temacs failed due to an
14597 undefined symbol __builtin_isnan. This is because
14598 /usr/include/iso/math_c99.h #defines isnan(x) to
14599 __builtin_isnan(x), but the bundled gcc, which identifies itself
14600 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14602 * floatfns.c (isnan): #undef, and then #define to a clone of
14604 (Fisnan): Always define, since it's always available now.
14605 (syms_of_floatfns): Always define isnan at the Lisp level.
14607 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14609 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14611 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14613 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14614 The previous code assumed that file offsets (off_t values) fit in
14615 EMACS_INT variables, which is not true on typical 32-bit hosts.
14616 The code messed up by falsely reporting buffer overflow in cases
14617 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14618 when "big" contains more than 2**29 bytes, even though this
14619 inserts just one byte and does not overflow the buffer.
14620 (Finsert_file_contents): Store file offsets as off_t
14621 values, not as EMACS_INT values. Check for overflow when
14622 converting between EMACS_INT and off_t. When checking for
14623 buffer overflow or for overlap, take the offsets into account.
14624 Don't use EMACS_INT for small values where int suffices.
14625 When checking for overlap, fix a typo: ZV was used where
14626 ZV_BYTE was intended.
14627 (Fwrite_region): Don't assume off_t fits into 'long'.
14628 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14630 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14632 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14634 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14636 sprintf-related integer and memory overflow issues (Bug#9412).
14638 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14639 (esprintf, exprintf, evxprintf): New functions.
14640 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14641 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14642 (modify_event_symbol): Do not assume that the length of
14643 name_alist_or_stem is safe to alloca and fits in int.
14644 (Fexecute_extended_command): Likewise for function name and binding.
14645 (Frecursion_depth): Wrap around reliably on integer overflow.
14646 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14647 since some callers pass EMACS_INT values.
14648 (Fsingle_key_description): Don't crash if symbol name contains more
14649 than MAX_ALLOCA bytes.
14650 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14651 (get_minibuffer): Arg is now EMACS_INT, not int.
14652 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14653 (esprintf, exprintf, evxprintf): New decls.
14654 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14656 * dbusbind.c (signature_cat): New function.
14657 (xd_signature, Fdbus_register_signal):
14658 Do not overrun buffer; instead, report string overflow.
14660 * dispnew.c (add_window_display_history): Don't overrun buffer.
14661 Truncate instead; this is OK since it's just a log.
14663 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14664 even if the time zone offset is outlandishly large.
14665 Don't mishandle offset == INT_MIN.
14667 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14668 when creating daemon; the previous buffer-overflow check was incorrect.
14670 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14671 which has the guts of the old verror function.
14673 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14674 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14676 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14677 (font_unparse_xlfd): Don't blindly alloca long strings.
14678 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14679 fits in int, when using sprintf. Use single snprintf to count
14680 length of string rather than counting it via multiple sprintfs;
14681 that's simpler and more reliable.
14682 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14683 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14684 sprintf, in case result does not fit in int.
14686 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14687 (fontset_from_font): Print it.
14689 * frame.c (tty_frame_count): Now printmax_t, not int.
14690 (make_terminal_frame, set_term_frame_name): Print it.
14691 (x_report_frame_params): In X, window IDs are unsigned long,
14692 not signed long, so print them as unsigned.
14693 (validate_x_resource_name): Check for implausibly long names,
14694 and don't assume name length fits in 'int'.
14695 (x_get_resource_string): Don't blindly alloca invocation name;
14696 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14699 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14700 (xg_check_special_colors, xg_set_geometry):
14701 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14703 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14704 Use esprintf, not sprintf, in case result does not fit in int.
14706 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14707 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14708 it as a large positive number.
14709 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14710 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14712 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14713 in case result does not fit in int.
14715 * print.c (float_to_string): Detect width overflow more reliably.
14716 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14717 buffer overrun. Don't assume list length fits in 'int'. Treat
14718 print length of 0 as 0, not as infinity; to be consistent with other
14719 uses of print length in this function. Don't overflow print length
14720 index. Don't assume hash table size fits in 'long', or that
14721 vectorlike size fits in 'unsigned long'.
14723 * process.c (make_process): Use printmax_t, not int, to format
14724 process-name gensyms.
14726 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14728 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14729 to avoid potential buffer overrun.
14731 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14732 if X resource line is longer than 512 bytes.
14734 * xfns.c (x_window): Make sprintf buffer a bit bigger
14735 to avoid potential buffer overrun.
14737 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14739 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14741 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14743 Integer overflow fixes for scrolling, etc.
14744 Without these, Emacs silently mishandles large integers sometimes.
14745 For example, "C-u 4294967297 M-x recenter" was treated as if
14746 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14748 * xdisp.c (try_window_id): Check Emacs fixnum range before
14749 converting to 'int'.
14751 * window.c (window_scroll_line_based, Frecenter):
14752 Check that an Emacs fixnum is in range before assigning it to 'int'.
14753 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14754 values converted from Emacs fixnums.
14755 (Frecenter): Don't wrap around a line count if it is out of 'int'
14756 range; instead, treat it as an extreme value.
14757 (Fset_window_configuration, compare_window_configurations):
14758 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14760 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14761 that can exceed INT_MAX. Check that EMACS_INT value is in range
14762 before assigning it to the (possibly-narrower) index.
14763 (match_limit): Don't assume that a fixnum can fit in 'int'.
14765 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14768 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14769 (Fvertical_motion): Don't wrap around LINES values that don't fit
14770 in 'int'. Instead, treat them as extreme values. This is good
14771 enough for windows, which can't have more than INT_MAX lines anyway.
14773 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14775 * Require libxml/parser.h to avoid compilation warning.
14777 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14779 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14780 since this reportedly can destroy thread storage.
14782 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14784 * syntax.c (find_defun_start): Update all cache variables if
14785 exiting early (Bug#9401).
14787 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14789 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14791 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14792 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14793 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14795 * term.c (tty_append_glyph): New function.
14796 (produce_stretch_glyph): Static function and its prototype deleted.
14798 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14801 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14803 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14804 when checking :margin (Bug#9390).
14805 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14806 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14807 so that the name doesn't mislead. All uses changed.
14809 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14811 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14814 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14816 * xdisp.c (move_it_to): Don't bail out early when reaching
14817 position beyond to_charpos, if we are scanning backwards.
14818 (move_it_vertically_backward): When DY == 0, make sure we get to
14819 the first character in the line after the newline.
14821 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14823 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14824 (ccl_driver): Do not generate an out-of-range pointer.
14825 (Fccl_execute_on_string): Remove unnecessary check for
14826 integer overflow, noted by Stefan Monnier in
14827 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14828 Remove a FIXME that didn't need fixing.
14829 Simplify the newly-introduced buffer reallocation code.
14831 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14833 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14835 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14837 Integer and memory overflow issues (Bug#9196).
14839 * doc.c (get_doc_string): Rework so that
14840 get_doc_string_buffer_size is the actual buffer size, rather than
14841 being 1 less than the actual buffer size; this makes xpalloc more
14844 * image.c (x_allocate_bitmap_record, cache_image):
14845 * xselect.c (Fx_register_dnd_atom):
14846 Simplify previous changes by using xpalloc.
14848 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14849 since either will do and ptrdiff_t is convenient with xpalloc.
14851 * charset.c (charset_table_size)
14852 (struct charset_sort_data.priority): Now ptrdiff_t.
14853 (charset_compare): Don't overflow if priorities differ greatly.
14854 (Fsort_charsets): Don't assume list length fits in int.
14855 Check for size-calculation overflow when allocating sort data.
14856 (syms_of_charset): Allocate an initial charset table that is
14857 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14859 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14861 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14862 The actual value is always <= INT_MAX, and leaving it unsigned made
14863 overflow checking harder.
14865 * dispextern.h (struct glyph_matrix.rows_allocated)
14866 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14867 with xpalloc. The values are still always <= INT_MAX.
14869 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14871 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14872 (SAFE_NALLOCA): New macro.
14874 * region-cache.c (struct boundary.pos, find_cache_boundary)
14875 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14876 (set_cache_region, invalidate_region_cache)
14877 (revalidate_region_cache, know_region_cache, region_cache_forward)
14878 (region_cache_backward, pp_cache):
14879 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14880 so that ptrdiff_t * can be passed to xpalloc.
14881 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14882 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14883 (pp_cache): Don't assume cache_len fits in int.
14884 * region-cache.h: Adjust extern decls to match.
14886 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14887 EMACS_INT, since either will do, for xpalloc.
14889 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14890 (xnmalloc, xnrealloc, xpalloc): New functions.
14892 * bidi.c (bidi_shelve_header_size): New constant.
14893 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14894 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14896 * bidi.c (bidi_cache_shrink):
14897 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14899 Don't update size of array until after memory allocation succeeds,
14900 because xmalloc/xrealloc may not return.
14901 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14902 now that we have proper integer overflow checking.
14903 (record_overlay_string, overlay_strings): Catch overflows when
14904 calculating size of overlay_str_buf.
14906 * callproc.c (Fcall_process): Check for size overflow when
14907 calculating size of args2.
14908 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14909 Normally we prefer signed values, but sticking with ptrdiff_t would
14910 require adding more-complicated checks.
14912 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14913 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14914 Redo buffer-overflow calculations to avoid integer overflow.
14915 Add a FIXME comment where memory seems to be over-allocated.
14917 * character.c (Fstring): Check for size-calculation overflow.
14919 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14920 unnecessary integer overflow. Check for size overflow.
14921 (encode_coding_object): Don't update size until xmalloc succeeds.
14923 * composite.c (get_composition_id): Check for overflow in glyph
14924 length calculations.
14926 Integer and memory overflow fixes for display code.
14927 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14928 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14929 (scrolling_window): Check for overflow in size calculations.

14933 (row_table_size): Now ptrdiff_t, not int.
14934 (scrolling_window): Avoid overflow in size calculations.
14935 Don't update size until allocation succeeds.
14936 * fns.c (concat): Check for overflow in size calculations.
14937 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14938 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

14941 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14942 (get_doc_string): Check for size calculation overflow.
14943 Don't update size until allocation succeeds.
14944 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14945 EMACS_INT, where ptrdiff_t will do.
14946 (Fsubstitute_command_keys): Check for string overflow.
14948 * editfns.c (set_time_zone_rule): Don't assume environment length
14950 (message_length): Now ptrdiff_t, not int.
14951 (Fmessage_box): Don't update size until allocation succeeds.
14952 Don't assume message length fits in int.
14953 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14955 * emacs.c (main): Do not reallocate argv, since there is a null at
14956 the end that can be overwritten, and this way there's no need to
14957 worry about size-calculation overflow.
14958 (sort_args): Check for size-calculation overflow.
14960 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14962 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14964 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14965 (x_set_scroll_bar_width, x_figure_window_size):
14966 Check for integer overflow.
14967 (x_set_alpha): Do not assume XINT fits in int.
14969 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14970 This is for the members text_lines, text_cols, total_lines, total_cols,
14971 where the system imposes an 'int' limit.
14973 * fringe.c (Fdefine_fringe_bitmap):
14974 Don't update size until alloc works.
14976 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14977 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14979 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14980 Check for size-calculation overflow.
14981 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14982 do, as we prefer signed integers.
14983 (id_to_widget.max_size, id_to_widget.used)
14984 (xg_store_widget_in_map, xg_remove_widget_from_map)
14985 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14986 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14987 Use and return ptrdiff_t, not int.
14988 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14989 * gtkutil.h: Change prototypes to match the above.
14991 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14992 are duplicate now that they've been promoted to lisp.h.
14993 (x_allocate_bitmap_record, x_alloc_image_color)
14994 (make_image_cache, cache_image, xpm_load):
14995 Don't update size until alloc is done.
14996 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
14998 Check for size calculation overflow.
14999 (ct_colors_allocated_max): New constant.
15000 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15003 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15004 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15005 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15006 Use ptrdiff_t, not int, to count maps.
15007 (read_char_minibuf_menu_prompt): Check for overflow in size
15008 calculations. Don't update size until allocation succeeds.
15009 Redo calculations to avoid overflow.
15010 * keyboard.h: Change prototypes to match the above.
15012 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15014 (current_minor_maps): Check for size calculation overflow.
15015 * keymap.h: Change prototypes to match the above.
15017 * lread.c (read1, init_obarray): Don't update size until alloc done.
15019 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15020 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15022 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15023 Now ptrdiff_t, not int.
15024 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

15036 (Fset_match_data): Don't assume list lengths fit in 'int'.
15038 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15039 for command line length. Do not attempt to address one before the
15040 beginning of an array, as that's not portable.
15042 * term.c (max_frame_lines): Remove; unused.
15043 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15045 (encode_terminal_code, calculate_costs): Check for size
15046 calculation overflow.

15049 done. Redo calculations to avoid overflow.
15050 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15052 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15053 subtracting pointers.
15054 (gobble_line): Check for overflow more carefully. Don't update size
15057 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

15068 Use ptrdiff_t, not int, for sizes.
15069 (Finternal_make_lisp_face, cache_face):
15070 Check for size calculation overflow.
15071 (cache_face): Treat size calculation overflows as if they were
15072 memory exhaustion (the usual treatment), rather than aborting.
15074 * xfns.c (x_encode_text, x_set_name_internal)
15075 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15076 sizes, since they can exceed INT_MAX in size. Check for size
15077 calculation overflow.
15079 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15080 (xg_select): Check for size calculation overflow.
15081 Don't update size until alloc done.
15083 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15084 as sprintf is limited to int lengths.
15086 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15087 (X_LONG_MIN): New macros.
15088 Use them to make the following changes clearer.
15089 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15090 This change doesn't affect the value now, but it may help remind
15091 future maintainers not to raise the value too much later.
15092 (SELECTION_QUANTUM): Remove, replacing with ...
15093 (selection_quantum): ... new function, which avoids overflow.
15095 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15096 assumption that selection length fits in 'int'.
15097 (x_reply_selection_request, x_handle_selection_request)
15098 (x_get_window_property, receive_incremental_selection)
15099 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15100 (lisp_data_to_selection_data, clean_local_selection_data):

15102 (x_reply_selection_request, x_get_window_property)
15103 (receive_incremental_selection, x_property_data_to_lisp):
15104 Redo calculations to avoid overflow.
15105 (x_reply_selection_request): When sending hint, ceiling it at
15106 X_LONG_MAX rather than relying on wraparound overflow to send
15108 (x_get_window_property, receive_incremental_selection)
15109 (lisp_data_to_selection_data, x_property_data_to_lisp):
15110 Check for size-calculation overflow.
15111 (x_get_window_property, receive_incremental_selection)
15112 (lisp_data_to_selection_data, Fx_register_dnd_atom):
15113 Don't store size until memory allocation succeeds.
15114 (x_get_window_property): Plug memory leak on memory exhaustion.
15115 Don't double-block input; malloc is safe here. Don't assume 2**34
15116 - 4 fits in unsigned long. Add an xassert to check
15117 XGetWindowProperty overflow. Be more careful about overflow
15118 calculations, and distinguish size from memory overflow better.
15119 (receive_incremental_selection): When tracing, don't assume
15120 unsigned int is less than INT_MAX.
15121 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15122 harmful) conversions of unsigned short to int.
15123 (lisp_data_to_selection_data): Don't assume that integers
15124 in the range -65535 through -1 fit in an X unsigned short.
15125 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15126 result parameters unless successful. Rely on cons_to_unsigned
15127 to report problems with elements; the old code wasn't right anyway.
15128 (x_check_property_data): Check for int overflow; we cannot use
15129 a wider type due to X limits.
15130 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15132 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

15161 * image.c (xpm_get_color_table_h):
15162 * lisp.h (hash_lookup, hash_put):
15163 * minibuf.c (Ftest_completion):
15164 Use ptrdiff_t for hash table indexes, not int (which is too
15165 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15166 32-bit --with-wide-int hosts).
15168 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15169 Add a FIXME comment about memory leaks.
15170 (syms_of_charset): Don't assume xmalloc returns.
15172 Don't assume that stated character widths fit in int.
15173 * character.c (Fchar_width, c_string_width, lisp_string_width):
15174 * character.h (CHAR_WIDTH):
15175 * indent.c (MULTIBYTE_BYTES_WIDTH):
15176 Use sanitize_char_width to avoid undefined and/or bad behavior
15177 with outlandish widths.
15178 * character.h (sanitize_tab_width): Rename from sanitize_width,
15179 now that we have two such functions. All uses changed.
15180 (sanitize_char_width): New inline function.
15182 Don't assume that tab-width fits in int.
15183 * character.h (sanitize_width): New inline function.
15184 (SANE_TAB_WIDTH): New macro.
15185 (ASCII_CHAR_WIDTH): Use it.

15190 * fileio.c: Integer overflow issues with file modes.
15191 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15193 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15194 Remove unreachable code.
15195 (read_hex, load_charset_map_from_file): Check for integer overflow.
15197 * xterm.c: Don't go over XClientMessageEvent limit.
15198 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15199 (x_send_scroll_bar_event): Likewise. Check that the size does not
15200 exceed limits imposed by XClientMessageEvent, as well as the usual
15201 ptrdiff_t and size_t limits.
15203 * keyboard.c: Overflow, signedness and related fixes.
15204 (make_lispy_movement): Use same integer type in forward decl
15205 that is used in the definition.
15206 (read_key_sequence, keyremap_step):
15207 Change bufsize argument back to int, undoing my 2011-03-30 change.
15208 We prefer signed types, and int is wide enough here.
15209 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15210 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15211 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15212 length, not size_t. Use ptrdiff_t for index, not int.
15213 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15214 possibility of integer overflow.
15216 Overflow, signedness and related fixes for images.
15218 * dispextern.h (struct it.stack[0].u.image.image_id)
15219 (struct_it.image_id, struct image.id, struct image_cache.size)

15226 * xdisp.c (calc_pixel_width_or_height):
15227 * xfns.c (image_cache_refcount):
15228 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
15229 on typical 64-bit hosts.

15235 when the callers expect that.
15236 (image_ascent): Redo ascent calculation to avoid int overflow.
15237 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15238 (lookup_image): Remove unnecessary tests.
15239 (xbm_image_p): Locals are now of int, not EMACS_INT,
15240 since parse_image_check makes sure they fit into int.
15241 (png_load, gif_load, svg_load_image):
15242 Prefer int to unsigned where either will do.
15243 (tiff_handler): New function, combining the cores of the
15244 old tiff_error_handler and tiff_warning_handler.
15245 This function is rewritten to use vsnprintf and thereby avoid
15246 stack buffer overflows. It uses only the features of vsnprintf
15247 that are common to both POSIX and native Microsoft.
15248 (tiff_error_handler, tiff_warning_handler): Use it.
15249 (tiff_load, gif_load, imagemagick_load_image):
15250 Don't assume :index value fits in 'int'.
15251 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15252 (imagemagick_load_image): Check that crop parameters fit into
15253 the integer types that MagickCropImage accepts. Don't assume
15254 Vimagemagick_render_type has a nonnegative value. Don't assume
15255 size_t fits in 'long'.
15256 (gs_load): Use printmax_t to print the widest integers possible.
15257 Check for integer overflow when computing image height and width.

15266 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15267 the display spec is of the form `(space ...)'.
15268 (handle_display_spec): Return the value returned by
15269 handle_single_display_spec, not just 1 or zero.
15270 (handle_single_display_spec): If the display spec is of the form
15271 `(space ...)', and specifies display in the text area, return 2
15273 (try_cursor_movement): Check for the need to scroll more
15274 accurately, and prefer exact match for point under bidi.
15275 Don't advance `row' beyond the last row of the window.
15277 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15278 into disp_prop; all users changed.
15280 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15281 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15282 for the text covered by the display property.

15292 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15293 buffers, return left-to-right.
15294 (set_cursor_from_row): Consider candidate row a win if its glyph
15295 represents a newline and point is on that newline. Fixes cursor
15296 positioning on the newline at EOL of R2L text within L2R
15297 paragraph, and vice versa.
15298 (try_cursor_movement): Check continued rows, in addition to
15299 continuation rows. Fixes unwarranted scroll when point enters a
15300 continued line of R2L text within an L2R paragraph, or vice versa.
15301 (cursor_row_p): Consider the case of point being equal to
15302 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15303 from the end of a short line to the beginning of a continued line
15304 of R2L text within L2R paragraph.
15305 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15306 composed characters.
15308 * bidi.c (bidi_check_type): Use xassert.

15321 2011-08-22 Kenichi Handa <handa@m17n.org>
15323 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15324 extra slot even if the purpose is char-code-property-table.
15326 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15328 * xdisp.c (redisplay_window): When computing centering_position,
15329 account for the height of the header line. (Bug#8874)
15331 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15332 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15333 candidate is selected by the mouse, and that candidate has a
15334 composed character under the mouse.
15336 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15337 coordinates reported by pos-visible-in-window-p for a composed
15338 character in column zero.
15340 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15342 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15344 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15346 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15347 consider it a hit if to_charpos is anywhere in the range of the
15348 composed buffer positions.
15350 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15352 * image.c (gif_load): Don't assume that each subimage has the same
15353 dimensions as the base image. Handle disposal method that is
15354 "undefined" by the gif spec (Bug#9335).
15356 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15358 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15361 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15363 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15364 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15365 from an Org mode buffer to a Speedbar frame.
15367 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15368 a composition, take its buffer position from IT->cmp_it.charpos.
15369 Fixes cursor positioning at the beginning of a line that begins
15370 with a composed character.
15372 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15374 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15375 character bidirectional type, use STRONG_L instead. Fixes crashes
15376 in a buffer produced by `describe-categories'.
15378 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15379 members before the level stack, so they would be saved and
15380 restored when copying iterator state. Fixes incorrect reordering
15381 around TABs covered by display properties.
15383 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15385 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15390 (internal_condition_case_2, internal_condition_case_n):
15391 Remove unnecessary aborts (Bug#9081).
15393 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15395 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15396 has no `load' handler, try opening the file locally. (Bug#9311)
15398 2011-08-16 Ken Brown <kbrown@cornell.edu>
15400 * gmalloc.c: Expand comment.
15402 2011-08-16 Eli Zaretskii <eliz@gnu.org>
15404 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
15405 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

15450 * process.c (create_process): Call setup_process_coding_systems
15451 after the pid of the process is set to -1 (Bug#8162).
15453 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15455 * xdisp.c (move_it_in_display_line_to): Don't invoke
15456 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15457 ppos_it. Fixes vertical cursor motion when line beginning is
15458 covered by an image. (Bug#9296)
15460 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15462 * nsterm.h (ns_run_ascript): Declare.

15466 (ns_run_ascript): New function.
15467 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15468 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15469 the event loop. Get status from as_status (Bug#7276).
15471 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15472 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15473 the event loop (Bug#7276).
15475 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

15498 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15499 (Fnetwork_interface_list): Allocate in increments of bytes instead
15500 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15501 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15503 (struct ifflag_def): notrailers is smart on OSX.
15504 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15505 Get hardware address with getifaddrs if available.
15507 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15509 * xdisp.c (iterate_out_of_display_property): xassert that
15510 IT->position is set to within IT->object's boundaries. Break from
15511 the loop as soon as EOB is reached; avoids infloops in redisplay
15512 when IT->position is set up wrongly due to some bug.
15513 Set IT->current to match the bidi iterator unconditionally.
15514 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15515 entry. Force push_it to save on the stack the current
15516 buffer/string position, to be restored by pop_it. Fix flags in
15517 the iterator structure wrt the object coming from a display
15518 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15519 properties. (Bug#9284)
15521 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15523 * fontset.c (fontset_get_font_group): Add proper type checks.

15536 no-display-properties-and-no-overlays under bidi display.
15537 Set disp_pos in the bidi iterator to avoid searches for display
15538 properties and overlays.
15540 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15542 * editfns.c (Fset_time_zone_rule): Document relationship with the

15548 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15550 * composite.c (autocmp_chars): Don't reset point. That is done by
15551 restore_point_unwind (Bug#5984).
15553 2011-08-07 Juri Linkov <juri@jurta.org>
15555 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15556 to show the arg `TIME' instead of `TIMEVAL'.
15558 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15560 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15561 display property strides EOL and includes a newline, as in
15562 longlines-mode. (Bug#9254)
15563 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15564 word-wrap under bidirectional display. (Bug#9224)
15566 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15567 is non-zero, even if the data buffer is NULL. Fixes a crash in
15568 vertical-motion with longlines-mode. (Bug#9254)
15570 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15572 * bidi.c <bidi_cache_total_alloc>: Now static.
15573 (bidi_initialize): Initialize bidi_cache_total_alloc.
15575 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15578 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15579 amount allocated this far in `bidi_cache_total_alloc'.
15580 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15581 non-zero, only free the data buffer without restoring the cache
15582 contents. All callers changed.
15584 * dispextern.h (bidi_unshelve_cache): Update prototype.
15586 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15587 (move_it_in_display_line, move_it_to)
15588 (move_it_vertically_backward, move_it_by_lines): Replace the call
15589 to xfree to an equivalent call to bidi_unshelve_cache.
15590 (move_it_in_display_line_to): Fix logic of returning
15591 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15593 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15595 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15596 came from a string character with a `cursor' property. (Bug#9229)
15598 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15600 * Makefile.in (LIB_PTHREAD): New variable.
15601 (LIBES): Add LIB_PTHREAD (Bug#9216).
15603 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:

15608 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15610 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15612 * xterm.c (x_find_topmost_parent): New function.
15613 (x_set_frame_alpha): Find topmost parent window with
15614 x_find_topmost_parent and set the property there also (bug#9181).
15615 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15617 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15619 * callproc.c (Fcall_process): Avoid vfork clobbering
15620 the local vars buffer, coding_systems, current_dir.
15622 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15624 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15626 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15628 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15629 so that it is not optimized away.
15631 * xdisp.c (compute_display_string_pos): Remove unused local.
15633 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15635 Fix slow cursor motion and scrolling in large buffers with
15636 selective display, like Org Mode buffers. (Bug#9218)
15638 * dispextern.h (struct bidi_it): New member disp_prop_p.
15640 * xdisp.c: Remove one-slot cache of display string positions.
15641 (compute_display_string_pos): Accept an additional argument
15642 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15643 for a display string or property. If found, set DISP_PROP_P
15646 * bidi.c (bidi_fetch_char): Accept an additional argument
15647 DISP_PROP_P, and pass it to compute_display_string_pos.
15648 Only handle text covered by a display string if DISP_PROP_P is returned
15649 non-zero. All callers of bidi_fetch_char changed.
15651 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15653 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15655 2010-12-03 Don March <don@ohspite.net>
15657 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15658 last character M-[char] is translated to ESC [char] (bug#7541).
15660 2011-08-02 Kenichi Handa <handa@m17n.org>
15662 * lisp.h (uniprop_table): Extern it.
15664 * chartab.c (uniprop_table): Make it non-static.
15666 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15668 * xdisp.c (forward_to_next_line_start): Accept additional argument
15669 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15671 (reseat_at_next_visible_line_start): Use the bidi iterator state
15672 returned by forward_to_next_line_start to restore the state of
15673 it->bidi_it after backing up to previous newline. (Bug#9212)
15675 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15677 * regex.c (re_comp): Protoize.
15678 (re_exec): Fix return type.
15679 (regexec): Fix type of `ret'. (Bug#9203)
15681 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15683 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15684 This is needed if max-image-size is a floating-point number.
15686 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15688 * print.c (print_object): Print empty symbol as ##.
15690 * lread.c (read1): Read ## as empty symbol.
15692 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15694 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15695 setting frame foreground color (Bug#9175).
15696 (x_set_background_color): Likewise.
15698 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15699 contents (Bug#9176).
15700 (EmacsTooltip -init): Remove bezels and add shadows to
15703 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15704 or scroll bar (Bug#8470).
15706 * nsfont.m (nsfont_open): Remove assignment to voffset and
15707 unnecessary vars hshink, expand, hd, full_height, min_height.
15708 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15710 * nsterm.h (nsfont_info): Remove voffset field.
15712 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15714 Implement strike-through and overline on NextStep (Bug#8863).
15716 * nsfont.m (nsfont_open): Use underline position provided by font,
15717 instead of hard-coded value of 2.
15718 (nsfont_draw): Call ns_draw_text_decoration instead.
15720 * nsterm.h: Add declaration for ns_draw_text_decoration.
15722 * nsterm.m (ns_draw_text_decoration): New function for drawing
15723 underline, overline, and strike-through.
15724 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15725 ns_draw_text_decoration. Change treatment of cursor drawing to
15726 accommodate underlining, etc.
15728 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15730 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15733 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15735 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15736 Without this fix, if a signal arrives just after memory fills up,
15737 'malloc' might be invoked reentrantly.
15739 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15740 In other words, assume that every image size is allowed, on non-X
15741 hosts. This assumption is probably wrong, but it lets Emacs compile.
15743 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15745 * regex.c (re_iswctype): Convert return values to boolean.
15747 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15749 * xdisp.c (compute_display_string_pos): Don't use cached display
15750 string position if the buffer had its restriction changed.
15753 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15755 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15757 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15759 Integer signedness and overflow and related fixes. (Bug#9079)
15761 * bidi.c: Integer size and overflow fixes.
15762 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15763 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15764 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15765 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15766 (bidi_find_other_level_edge):
15767 Use ptrdiff_t instead of EMACS_INT where either will do.
15768 This works better on 32-bit hosts configured --with-wide-int.
15769 (bidi_cache_ensure_space): Check for size-calculation overflow.
15770 Use % rather than repeated addition, for better worst-case speed.
15771 Don't set bidi_cache_size until after xrealloc returns, because it
15773 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15774 (bidi_cache_ensure_space): Also check that the bidi cache size
15775 does not exceed that of the largest Lisp string or buffer. See Eli
15776 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15778 * alloc.c (__malloc_size_t): Remove.
15779 All uses replaced by size_t. See Andreas Schwab's note
15780 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15782 * image.c: Improve checking for integer overflow.
15783 (check_image_size): Assume that f is nonnull, since
15784 it is always nonnull in practice. This is one less thing to
15785 worry about when checking for integer overflow later.
15786 (x_check_image_size): New function, which checks for integer
15787 overflow issues inside X.
15788 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15789 This removes the need for a memory_full check.
15790 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15791 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15792 (xbm_read_bitmap_data): Change locals back to 'int', since
15793 their values must fit in 'int'.
15794 (xpm_load_image, png_load, tiff_load):
15795 Invoke x_create_x_image_and_pixmap earlier,
15796 to avoid much needless work if the image is too large.
15797 (tiff_load): Treat overly large images as if
15798 x_create_x_image_and_pixmap failed, not as malloc failures.
15799 (gs_load): Use x_check_image_size.
15801 * gtkutil.c: Omit integer casts.
15802 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15803 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15805 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15807 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15808 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15809 would wrongly return t on a 64-bit host.
15811 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15812 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15813 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15814 and therefore cause GCC to emit a bogus diagnostic in some cases.
15816 * image.c: Integer signedness and overflow and related fixes.
15817 This is not an exhaustive set of fixes, but it's time to
15818 record what I've got.
15819 (lookup_pixel_color, check_image_size): Remove redundant decls.
15820 (check_image_size): Don't assume that arbitrary EMACS_INT values
15821 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15822 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15823 (tiff_load, imagemagick_load_image):
15824 Check for overflow in size calculations.
15825 (x_create_x_image_and_pixmap): Remove unnecessary test for
15826 xmalloc returning NULL; that can't happen.
15827 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15828 (xpm_color_bucket): Use better integer hashing function.
15829 (xpm_cache_color): Don't possibly over-allocate memory.
15830 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15831 (gif_memory_source):
15832 Use ptrdiff_t, not int or size_t, to record sizes.
15833 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15834 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15835 either works, as we prefer signed integers.
15836 (tiff_read_from_memory, tiff_write_from_memory):
15837 Return tsize_t, not size_t, since that's what the TIFF API wants.
15838 (tiff_read_from_memory): Don't fail simply because the read would
15839 go past EOF; instead, return a short read.
15840 (tiff_load): Omit no-longer-needed casts.
15841 (Fimagemagick_types): Don't assume size fits into 'int'.
15843 Improve hashing quality when configured --with-wide-int.
15844 * fns.c (hash_string): New function, taken from sxhash_string.
15845 Do not discard information about ASCII character case; this
15846 discarding is no longer needed.
15847 (sxhash-string): Use it. Change sig to match it. Caller changed.
15848 * lisp.h: Declare it.
15849 * lread.c (hash_string): Remove, since we now use fns.c's version.
15850 The fns.c version returns a wider integer if --with-wide-int is
15851 specified, so this should help the quality of the hashing a bit.
15853 * emacs.c: Integer overflow minor fix.
15854 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15855 Define only if GNU_LINUX.
15856 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15858 * dispnew.c: Integer signedness and overflow fixes.
15859 Remove unnecessary forward decls, that were a maintenance hassle.
15860 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15862 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15863 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15864 (prepare_desired_row, line_draw_cost):
15865 Use int, not unsigned, where either works.
15866 (save_current_matrix, restore_current_matrix):
15867 Use ptrdiff_t, not size_t, where either works.
15868 (init_display): Check for overflow more accurately, and without
15869 relying on undefined behavior.
15871 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15872 Remove, replacing with the new symbols in lisp.h. All uses changed.
15873 * fileio.c (make_temp_name):
15874 * filelock.c (lock_file_1, lock_file):
15875 * xdisp.c (message_dolog):
15876 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15877 Use pMd etc. instead.
15878 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15879 replacing the pWIDE etc. symbols removed from editfns.c.
15881 * keyboard.h (num_input_events): Now uintmax_t.
15882 This is (very slightly) less likely to mess up due to wraparound.
15885 * buffer.c: Integer signedness fixes.
15886 (alloc_buffer_text, enlarge_buffer_text):
15887 Use ptrdiff_t rather than size_t when either will do, as we prefer
15890 * alloc.c: Integer signedness and overflow fixes.
15891 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15892 (__malloc_size_t): Default to size_t, not to int.
15893 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15894 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15895 Prefer ptrdiff_t to size_t when either would do, as we prefer
15897 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15898 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15899 Now const. Initialize with values that are in range even if char
15901 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15902 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15903 These functions do the right thing with sizes > 2**32.
15904 (check_depth): Now ptrdiff_t, not int.
15905 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15906 Adjust to new way of storing sizes. Check for size overflow bugs
15908 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15909 slightly wrong anyway, as it missed one instance of
15910 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15911 (refill_memory_reserve): Omit needless cast to size_t.
15912 (mark_object_loop_halt): Mark as externally visible.
15914 * xselect.c: Integer signedness and overflow fixes.
15915 (Fx_register_dnd_atom, x_handle_dnd_message):
15916 Use ptrdiff_t, not size_t, since we prefer signed.
15917 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15918 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15919 x_dnd_atoms_size and x_dnd_atoms_length.
15921 * doprnt.c: Prefer signed to unsigned when either works.
15923 * doprnt.c (doprnt):
15925 * xdisp.c (vmessage):
15926 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15927 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15928 prefer signed arithmetic to avoid comparison confusion.
15929 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15930 but is a bit tricky.
15932 Assume freestanding C89 headers, string.h, stdlib.h.
15933 * data.c, doprnt.c, floatfns.c, print.c:
15934 Include float.h unconditionally.
15935 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15936 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15937 * regex.c: Likewise for stddef.h, string.h.
15938 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15939 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15940 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15941 (STDC_HEADERS): Remove obsolete defines.
15942 * sysdep.c: Include limits.h unconditionally.
15944 Assume support for memcmp, memcpy, memmove, memset.
15945 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15946 * regex.c (memcmp, memcpy):
15947 Remove; we assume C89 now.
15949 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15950 (__malloc_safe_bcopy): Remove; no longer needed.
15952 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15953 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15954 well either way, and we prefer signed to unsigned.
15956 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15958 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15959 closes the connection while we're reading (bug#9182).
15961 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15963 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15964 are specified (Bug#9168).
15966 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15968 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15969 Found by GCC static checking and --with-wide-int on a 32-bit host.
15971 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15973 * xdisp.c (compute_display_string_pos): Fix logic of caching
15974 previous display string position. Initialize cached_prev_pos to
15975 -1. Fixes slow-down at the beginning of a buffer.
15977 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15979 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15980 for attrs[LFACE_FONTSET_INDEX].
15982 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15984 * xml.c (parse_region): Remove unused local
15985 that was recently introduced.
15987 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15989 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15990 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15992 * xdisp.c (move_it_in_display_line_to): Record the best matching
15993 position for TO_CHARPOS while scanning the line, and restore it on
15994 exit if none of the characters scanned was an exact match.
15995 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15996 when exact match is impossible due to invisible text, and the
15997 lines are truncated.
15999 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16001 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16004 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16006 Fix a significant slow-down of cursor motion with C-n, C-p,
16007 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16008 auto-repeat under bidi redisplay in fontified buffers.
16009 * xdisp.c (compute_stop_pos_backwards): New function.
16010 (next_element_from_buffer): Call compute_stop_pos_backwards to
16011 find a suitable prev_stop when we find ourselves before
16013 (reseat): Don't look for prev_stop, as that could mean a very long
16015 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16016 <cached_disp_overlay_modiff>: Cache for last found display string
16018 (compute_display_string_pos): Return the cached position if asked
16019 about the same buffer in the same area of character positions, and
16020 the buffer wasn't changed since the time the display string
16021 position was cached.
16023 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16025 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16026 is an integer, which is important for empty lines. (Bug#9149)
16028 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16030 * frame.c (Fmodify_frame_parameters): In tty case, update the
16031 default face if necessary (Bug#4238).
16033 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16035 * editfns.c (Fstring_to_char): No need to explain what a character
16036 is in the docstring (Bug#6576).
16038 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16040 * xml.c (parse_region): Make sure we always return a tree.
16042 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16044 * xml.c (parse_region): If a document contains only comments,
16047 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16049 * xml.c (make_dom): Return comments, too.
16051 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16054 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16055 and the surrounding thread.
16056 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16057 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16058 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16060 * s/openbsd.h (BROKEN_SIGIO): Define.
16061 * unexelf.c (unexec) [__OpenBSD__]:
16062 Don't update the .mdebug section of the Alpha COFF symbol table.
16064 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16066 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16069 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16071 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16072 This fixes some race conditions on the permissions of any newly
16075 * alloc.c (valid_pointer_p): Use pipe, not open.
16076 This fixes some permissions issues when debugging.
16078 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16079 If fchown fails to set both uid and gid, try to set just gid,
16080 as that is sometimes allowed. Adjust the file's mode to eliminate
16081 setuid or setgid bits that are inappropriate if fchown fails.
16083 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16085 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16086 to compare Lisp_Objects.

16091 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16093 * lread.c (read_integer): Unread even EOF character.
16094 (read1): Likewise. Properly record start position of symbol.

16097 symbol character follows.
16099 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16101 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16102 This works around a problem with the previous change to Fcopy_file.
16103 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16104 and without this change, GCC might complain about discarding
16105 fchown's return value.
16107 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16109 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16111 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16113 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16115 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16117 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16118 it's used from the C level.
16120 * process.c: Use the same condition for POLL_FOR_INPUT in both
16121 keyboard.c and process.c (bug#1858).
16123 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16125 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16126 (Fgnutls_boot): Use it.
16128 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16130 * doc.c (Fsubstitute_command_keys): Revert last change.
16132 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16134 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16135 quotes the next character, and doesn't affect other longer
16136 sequences (bug#8935).
16138 * lread.c (syms_of_lread): Clarify that is isn't only
16139 `eval-buffer' and `eval-defun' that's affected by
16140 `lexical-binding' (bug#8460).
16142 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16144 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16145 bidi redisplay when a line includes both an image and is truncated.
16147 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16149 Fix minor problems found by static checking.
16150 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16151 (elsz): Now a signed constant, not a size_t var. We prefer signed
16152 types to unsigned, to avoid integer comparison confusion. Without
16153 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16154 "cannot optimize loop, the loop counter may overflow", a symptom
16156 * indent.c (Fvertical_motion): Mark locals as initialized.
16157 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16159 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16161 * search.c (Fre_search_backward): Mention `case-fold-search' in
16162 all the re_search_* functions (bug#8138).

16185 (display_string): If we need to ignore text properties of
16186 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16187 original value of -1 will not work with bidi.)
16188 (compute_display_string_pos): First arg is now struct
16189 `text_pos *'; all callers changed. Support display properties on
16191 (compute_display_string_end): Support display properties on Lisp
16193 (init_iterator, reseat_1, reseat_to_string): Initialize the
16194 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16195 when iterating on a string not from display properties).
16196 (compute_display_string_pos, compute_display_string_end):
16197 Fix calculation of the object to scan. Fixes an error when using
16199 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16200 base_level_stop; instead, set base_level_stop to BEGV.
16201 Fixes crashes in vertical-motion.
16202 (next_element_from_buffer): Improve commentary for when
16203 the iterator is before prev_stop.
16204 (init_iterator): Initialize bidi_p from the default value of
16205 bidi-display-reordering, not from buffer-local value. Use the
16206 buffer-local value only if initializing for buffer iteration.

16216 (init_iterator): Don't initialize it->bidi_p for strings
16218 (reseat_to_string): Initialize it->bidi_p for strings here.

16227 parts of next_element_from_buffer, next_element_from_string, and
16228 next_element_from_c_string.
16229 (tool_bar_lines_needed, redisplay_tool_bar)
16230 (display_menu_bar): Force left-to-right direction. Add a FIXME
16231 comment for making that be controlled by a user option.

16241 iterator for displaying display or overlay strings.
16242 (forward_to_next_line_start): Don't use the shortcut if
16244 (back_to_previous_visible_line_start): If handle_display_prop
16245 pushed the iterator stack, restore the internal state of the bidi
16246 iterator by calling bidi_pop_it same number of times.
16247 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16248 and we are bidi-iterating, don't decrement the iterator position;
16249 instead, set the first_elt flag in the bidi iterator, to produce
16251 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16252 (push_display_prop): xassert that we are iterating a buffer.

16256 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16257 correctly. Don't assume unibyte strings are not bidi-reordered.

16265 popping after iteration over a string that came from a display
16266 property. Fix a typo in popping stretch info. Add an assertion
16267 for verifying that the iterator position is in sync with the bidi
16269 (handle_single_display_spec, get_overlay_strings_1)

16359 (struct iterator_stack_entry): New members bidi_p,
16360 paragraph_embedding, and from_disp_prop_p.

16414 The old code sometimes used this field without initializing it.
16416 * alloc.c (gc_sweep): Don't read past end of array.

16681 (clone_per_buffer_values): Don't assume that

16683 This isn't true in general, and it's particularly not true
16684 if Emacs is configured with --with-wide-int.
16685 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16686 New macros, used in the buffer.c change.

16722 Random fixes. E.g., (random) never returned negative values.
16723 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16724 subseconds part to the entropy, as that's a bit more random.
16725 Prefer signed to unsigned, since the signedness doesn't matter and
16726 in general we prefer signed. When given a limit, use a
16727 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16728 latter isn't right if USE_2_TAGS_FOR_INTS.
16729 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16730 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16734 * textprop.c (text_property_stickiness):

16742 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16743 This is more efficient than Ffile_directory_p and avoids a minor race.
16745 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16747 * buffer.c (Foverlay_put): Say what the return value is
16750 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16751 is a directory before asking whether to use the file name
16753 (barf_or_query_if_file_exists): Make the "File is a directory"
16754 error be more correct.
16756 * fns.c (Frequire): Remove the mention of the .gz files, since
16757 that's installation-specific, but keep the mention of
16758 `get-load-suffixes'.

16762 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16770 Qgnutls_bootprop_verify_error (which is no longer used).
16772 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16773 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16774 Also (re)move comments that are misplaced or no longer relevant.

16803 * lread.c (syms_of_lread): Mention single symbols defined by
16804 `defvar' or `defconst' (bug#7154).

16837 (syms_of_keymap): Defsubr make-composed-keymap.
16838 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16875 * eval.c (struct backtrace): Simplify and port the data structure.
16876 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16877 signed bit field, as this assumption is not portable and it makes
16878 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16879 "char debug_on_exit : 1" as this is not portable either; instead,
16880 use the portable "unsigned int debug_on_exit : 1". Remove unused
16881 member evalargs. Remove obsolete comments about cc bombing out.
16883 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16969 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
16971 * process.c (wait_reading_process_output): Bypass select if
16972 waiting for a cell while ignoring keyboard input, and input is
16973 pending. Suggested by Jan Djärv (Bug#8869).
16975 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
16977 Use gnulib's dup2 module instead of rolling our own.
16978 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

17049 * print.c (printchar, strout): Check for string overflow.
17050 (PRINTPREPARE, printchar, strout):
17051 Don't set size unless allocation succeeds.
17053 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17054 for sizes. Check for string overflow more accurately.
17055 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17057 * macros.c: Integer and buffer overflow fixes.
17058 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17059 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17063 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17065 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17067 * lread.c: Integer overflow fixes.
17068 (read_integer): Radix is now EMACS_INT, not int,
17069 to improve quality of diagnostics for out-of-range radices.
17070 Calculate buffer size correctly for out-of-range radices.
17071 (read1): Check for integer overflow in radices, and in
17072 read-circle numbers.
17073 (read_escape): Avoid int overflow.
17074 (Fload, openp, read_buffer_size, read1)
17075 (substitute_object_recurse, read_vector, read_list, map_obarray):

17091 2011-06-22 Leo Liu <sdl.web@gmail.com>
17093 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17094 Move to minibuffer.el.
17096 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17098 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17099 The following patches are for when GLYPH_DEBUG && !XASSERT.
17100 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17101 * dispnew.c (flush_stdout):
17102 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17103 Mark as externally visible.
17104 * dispnew.c (check_window_matrix_pointers): Now static.
17105 * dispnew.c (window_to_frame_vpos):
17106 * xfns.c (unwind_create_frame):
17107 * xterm.c (x_check_font): Remove unused local.
17108 * scroll.c (CHECK_BOUNDS):
17109 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17110 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17111 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17112 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17113 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17115 (debug_method_add): Use va_list and vsprintf rather than relying
17116 on undefined behavior with wrong number of arguments.
17117 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17118 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17119 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17120 since we're not interested in debugging glyphs with old libraries.
17121 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17122 GCC 4.6.0's static checking.
17124 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17126 Integer overflow and signedness fixes (Bug#8873).

17142 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17143 (.bitmaps_last, struct x_output.icon_bitmap):
17144 Use ptrdiff_t, not int, for bitmap indexes.
17145 (x_allocate_bitmap_record): Check for size overflow.
17146 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17148 Use ptrdiff_t, not int, for overlay counts.
17149 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17150 * editfns.c (overlays_around, get_pos_property):
17151 * textprop.c (get_char_property_and_overlay):
17152 * xdisp.c (next_overlay_change, note_mouse_highlight):
17153 * xfaces.c (face_at_buffer_position):
17154 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17155 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17156 (Fnext_overlay_change, Fprevious_overlay_change)
17157 (mouse_face_overlay_overlaps, Foverlays_in):
17158 Use ptrdiff_t, not int, for sizes.
17159 (overlays_at, overlays_in): Check for size-calculation overflow.
17161 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17163 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17164 (x_session_initialize): Do not assume string length fits in int.
17166 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17167 This is unlikely, but can occur if DPI is outlandish.
17169 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17170 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17172 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17173 * xrdb.c (magic_file_p, search_magic_path):
17174 Omit last arg SUFFIX; it was always 0. All callers changed.
17175 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17177 * xfont.c (xfont_match): Avoid need for strlen.
17179 * xfns.c: Don't assume strlen fits in int.

17182 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17183 not unsigned long, as we prefer signed integers. All callers changed.
17184 Detect integer overflow in repeat count.
17185 (message_dolog): Don't assume print length fits in 39 bytes.
17186 (display_mode_element): Don't assume strlen fits in int.
17188 * termcap.c: Don't assume sizes fit in int and never overflow.
17189 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17190 (gobble_line): Check for size-calculation overflow.
17192 * minibuf.c (Fread_buffer):
17193 * lread.c (intern, intern_c_string):

17198 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17200 * font.c: Don't assume string length fits in int.
17201 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17202 Use ptrdiff_t, not int.
17203 (font_intern_prop): Don't assume string length fits in int.
17204 Don't assume integer property fits in fixnum.
17205 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17207 * filelock.c: Fix some buffer overrun and integer overflow issues.
17208 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17209 Reformulate so as not to need the command string.
17210 Invoke gzip -cd rather than gunzip, as it's more portable.
17211 (lock_info_type, lock_file_1, lock_file):
17212 Don't assume pid_t and time_t fit in unsigned long.
17213 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17214 (current_lock_owner): Prefer signed type for sizes.
17215 Use memcpy, not strncpy, where memcpy is what is really wanted.
17216 Don't assume (via atoi) that time_t and pid_t fit in int.
17217 Check for time_t and/or pid_t out of range, e.g., via a network share.
17218 Don't alloca where an auto var works fine.
17220 * fileio.c: Fix some integer overflow issues.
17221 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17222 Don't assume string length fits in int.
17223 (directory_file_name): Don't assume string length fits in long.
17224 (make_temp_name): Don't assume pid fits in int, or that its print
17225 length is less than 20.
17227 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17229 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17231 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

17245 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17247 * lread.c (invalid_syntax): Omit length argument.
17248 All uses changed. This doesn't fix a bug, but it simplifies the
17249 code away from its former Hollerith-constant appearance, and it's
17250 one less 'int' to worry about when looking at integer-overflow issues.
17251 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17253 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17254 This didn't break anything, but it didn't help either.
17255 It's confusing to put a bogus integer in a place where the actual
17256 value does not matter.
17257 (LIST_END_P): Remove unused macro and its bogus comment.
17258 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17260 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17261 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17263 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17264 We prefer signed types, and the value cannot exceed the EMACS_INT
17265 range anyway (because otherwise the length would not be representable).
17266 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17267 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17268 This avoids a GCC warning when WIDE_EMACS_INT.
17270 * indent.c (sane_tab_width): New function.
17271 (current_column, scan_for_column, Findent_to, position_indentation)
17272 (compute_motion): Use it. This is just for clarity.
17273 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17275 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

17278 * composite.c (composition_gstring_put_cache):
17279 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17281 * editfns.c, insdel.c:
17282 Omit unnecessary forward decls, to simplify future changes.
17284 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17286 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17288 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17289 Use much-faster test for byte-length change.
17290 Don't assume string byte-length fits in 'int'.
17291 Check that character arg fits in 'int'.
17292 (mapcar1): Declare byte as byte, for clarity.
17294 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17296 * fns.c (concat): Catch string overflow earlier.
17297 Do not rely on integer wraparound.
17299 * dispextern.h (struct it.overlay_strings_charpos)
17300 (struct it.selective): Now EMACS_INT, not int.
17301 * xdisp.c (forward_to_next_line_start)
17302 (back_to_previous_visible_line_start)
17303 (reseat_at_next_visible_line_start, next_element_from_buffer):
17304 Don't arbitrarily truncate the value of 'selective' to int.
17306 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17308 * composite.c: Don't truncate sizes to 'int'.
17309 (composition_gstring_p, composition_reseat_it)
17310 (composition_adjust_point): Use EMACS_INT, not int.
17311 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17312 not EMACS_UINT, for indexes.
17314 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17316 * buffer.c: Include <verify.h>.
17317 (struct sortvec.priority, struct sortstr.priority):
17318 Now EMACS_INT, not int.
17319 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17320 (struct sortstr.size, record_overlay_string)
17321 (struct sortstrlist.size, struct sortlist.used):
17322 Don't truncate size to int.
17323 (record_overlay_string): Check for size-calculation overflow.
17324 (init_buffer_once): Check at compile-time, not run-time.
17326 2011-06-22 Jim Meyering <meyering@redhat.com>
17328 Don't leak an XBM-image-sized buffer
17329 * image.c (xbm_load): Free the image buffer after using it.
17331 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17334 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17335 that Sun C diagnosed.
17336 * fns.c (secure_hash): Fix pointer signedness issue.
17337 * intervals.c (static_offset_intervals): New function.
17338 (offset_intervals): Use it.
17340 2011-06-21 Leo Liu <sdl.web@gmail.com>
17343 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17346 * fns.c (secure_hash): Rename from crypto_hash_function and change
17347 the first arg to accept symbols.
17348 (Fsecure_hash): New primitive.
17349 (syms_of_fns): New symbols.
17351 2011-06-20 Deniz Dogan <deniz@dogan.se>
17353 * process.c (Fset_process_buffer): Clarify return value in
17356 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17358 * dispnew.c (add_window_display_history): Use BVAR.

17362 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17364 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17367 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17368 check till after the cache is created in init_frame_faces.
17370 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17372 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17374 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17376 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17377 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17378 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17380 Improve buffer-overflow checking (Bug#8873).
17381 * fileio.c (Finsert_file_contents):
17382 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17383 Remove the old (too-loose) buffer overflow checks.
17384 They weren't needed, since make_gap checks for buffer overflow.
17385 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17386 The old code merely checked for Emacs fixnum overflow, and relied
17387 on undefined (wraparound) behavior. The new code avoids undefined
17388 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17390 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17391 Tune. Don't use wider integers than needed. Don't use alloca.
17392 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17394 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17396 * insdel.c, lisp.h (buffer_overflow): New function.
17397 (insert_from_buffer_1, replace_range, replace_range_2):
17398 * insdel.c (make_gap_larger):
17399 * editfns.c (Finsert_char):
17400 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17402 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17404 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17406 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17408 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17409 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17411 * fileio.c: Don't assume EMACS_INT fits in off_t.
17412 (emacs_lseek): New static function.
17413 (Finsert_file_contents, Fwrite_region): Use it.
17414 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17416 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17418 * fns.c: Don't overflow int when computing a list length.
17419 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17420 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17421 truncation on 64-bit hosts. Check for QUIT every
17422 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17423 faster and is responsive enough.
17424 (Flength): Report an error instead of overflowing an integer.
17425 (Fsafe_length): Return a float if the value is not representable
17426 as a fixnum. This shouldn't happen except in contrived situations.
17427 (Fnthcdr, Fsort): Don't assume list length fits in int.
17428 (Fcopy_sequence): Don't assume vector length fits in int.
17430 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17431 (header_size, word_size): New constants.
17432 (allocate_vectorlike): Don't check size overflow here.
17433 (allocate_vector): Check it here instead, since this is the only
17434 caller of allocate_vectorlike that could cause overflow.
17435 Check that the new vector's length is representable as a fixnum.
17437 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17438 The previous code was bogus. For example, next_almost_prime (32)
17439 returned 39, which is undesirable as it is a multiple of 3; and
17440 next_almost_prime (24) returned 25, which is a multiple of 5 so
17441 why was the code bothering to check for multiples of 7?
17443 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17445 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17447 Variadic C functions now count arguments with ptrdiff_t.
17448 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17449 Back then I didn't know that the Emacs coding style prefers signed int.
17450 Also, in the meantime I found a few more instances where arguments
17451 were being counted with int, which may truncate counts on 64-bit
17452 machines, or EMACS_INT, which may be unnecessarily wide.
17453 * lisp.h (struct Lisp_Subr.function.aMANY)
17454 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17455 Arg counts are now ptrdiff_t, not size_t.
17456 All variadic functions and their callers changed accordingly.
17457 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17458 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17459 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17460 * callint.c (Fcall_interactively): Check arg count for overflow,
17461 to avoid potential buffer overrun. Use signed char, not 'int',
17462 for 'varies' array, so that we needn't bother to check its size
17463 calculation for overflow.
17464 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17465 * eval.c (apply_lambda):
17466 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17467 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17468 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17470 * callint.c (Fcall_interactively): Don't use index var as event count.
17472 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17473 * mem-limits.h (SIZE): Remove; no longer used.
17475 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17477 Remove unnecessary casts.
17478 * xterm.c (x_term_init):
17479 * xfns.c (x_set_border_pixel):
17480 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17481 These aren't needed now that we assume ANSI C.
17483 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17484 It's more likely to cause problems (due to unsigned overflow)
17487 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17489 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17491 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17493 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17495 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17497 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17499 GLYPH_CODE_FACE returns EMACS_INT, not int.
17500 * dispextern.h (merge_faces):
17501 * xfaces.c (merge_faces):
17502 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17503 Don't assume EMACS_INT fits in int.
17505 * character.h (CHAR_VALID_P): Remove unused parameter.
17506 * fontset.c, lisp.h, xdisp.c: All uses changed.
17508 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17510 * fns.c (concat): Minor tuning based on overflow analysis.
17511 This doesn't fix any bugs. Use int to hold character, instead
17512 of constantly refetching from Emacs object. Use XFASTINT, not
17513 XINT, for value known to be a character. Don't bother comparing
17514 a single byte to 0400, as it's always less.
17516 * floatfns.c (Fexpt):
17517 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17519 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17522 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17524 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17525 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17526 incorrectly succeed when S was a string, because 4294967386 was
17527 truncated before it was used.
17529 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17530 Otherwise, an out-of-range integer could cause undefined behavior
17533 * composite.c: Use int, not EMACS_INT, for characters.
17534 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17535 EMACS_INT, for values that are known to be in character range.
17536 This doesn't fix any bugs but is the usual style inside Emacs and
17537 may generate better code on 32-bit machines.
17539 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17540 This is for reasons similar to the recent CHAR_STRING fix.
17541 * charset.c (Fencode_char): Check that character arg is actually
17542 a character. Pass an int to ENCODE_CHAR.
17543 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17544 wider than 'int', as a compile-time check to prevent future regressions
17547 * character.c (char_string): Remove unnecessary casts.
17549 Make sure a 64-bit char is never passed to CHAR_STRING.
17550 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17551 by silently ignoring the top 32 bits, allowing some values
17552 that were far too large to be valid characters.
17553 * character.h: Include <verify.h>.
17554 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17555 arguments are no wider than unsigned, as a compile-time check
17556 to prevent future regressions in this area.
17558 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17559 (Fsubst_char_in_region):
17561 * xdisp.c (decode_mode_spec_coding):
17562 Adjust to CHAR_STRING's new requirement.
17563 * editfns.c (Finsert_char, Fsubst_char_in_region):
17564 * fns.c (concat): Check that character args are actually
17565 characters. Without this test, these functions did the wrong
17566 thing with wildly out-of-range values on 64-bit hosts.
17568 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17569 These casts should not be needed on 32-bit hosts, either.
17570 * keyboard.c (read_char):
17571 * lread.c (Fload): Remove casts to unsigned.
17573 * lisp.h (UNSIGNED_CMP): New macro.
17574 This fixes comparison bugs on 64-bit hosts.
17575 (ASCII_CHAR_P): Use it.
17576 * casefiddle.c (casify_object):
17577 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17578 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17579 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17580 * dispextern.h (FACE_FROM_ID):
17581 * keyboard.c (read_char): Use UNSIGNED_CMP.
17583 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17584 not to EMACS_INT, to avoid GCC warning.
17586 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17588 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17589 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17590 isn't needed on 32-bit machines.
17592 * buffer.c (Fgenerate_new_buffer_name):
17593 Use EMACS_INT for count, not int.
17594 (advance_to_char_boundary): Return EMACS_INT, not int.
17596 * data.c (Qcompiled_function): Now static.
17598 * window.c (window_body_lines): Now static.
17600 * image.c (gif_load): Rename local to avoid shadowing.
17602 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17603 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17604 * alloc.c (make_save_value): Integer argument is now of type
17605 ptrdiff_t, not int.
17606 (mark_object): Use ptrdiff_t, not int.
17607 * lisp.h (pD): New macro.
17608 * print.c (print_object): Use it.
17610 * alloc.c: Use EMACS_INT, not int, to count objects.
17611 (total_conses, total_markers, total_symbols, total_vector_size)
17612 (total_free_conses, total_free_markers, total_free_symbols)
17613 (total_free_floats, total_floats, total_free_intervals)
17614 (total_intervals, total_strings, total_free_strings):
17615 Now EMACS_INT, not int. All uses changed.
17616 (Fgarbage_collect): Compute overall total using a double, so that
17617 integer overflow is less likely to be a problem. Check for overflow
17618 when converting back to an integer.
17619 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17620 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17621 These were 'int' variables that could overflow on 64-bit hosts;
17622 they were never used, so remove them instead of repairing them.
17623 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17624 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17625 Previously, this ceilinged at INT_MAX, but that doesn't work on
17627 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17629 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17630 (allocate_vectorlike): Check for ptrdiff_t overflow.
17631 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17632 when a (possibly-narrower) signed value would do just as well.
17633 We prefer using signed arithmetic, to avoid comparison confusion.
17635 * alloc.c: Catch some string size overflows that we were missing.
17636 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17637 for convenience in STRING_BYTES_MAX.
17638 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17639 The definition here is exact; the one in lisp.h was approximate.
17640 (allocate_string_data): Check for string overflow. This catches
17641 some instances we weren't catching before. Also, it catches
17642 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17643 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17644 and ptrdiff_t and EMACS_INT are both 64 bits.
17646 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17647 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17648 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17650 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17652 * alloc.c (Fmake_string): Check for out-of-range init.
17654 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17656 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17658 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17660 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17661 xg_get_default_scrollbar_width.
17663 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17664 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17665 (style_changed_cb): Call update_theme_scrollbar_width and call
17666 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17667 all frames (Bug#8505).
17668 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17669 Call gtk_window_set_resizable if HAVE_GTK3.
17670 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17671 and height if HAVE_GTK3 (Bug#8505).
17672 (scroll_bar_width_for_theme): New variable.
17673 (update_theme_scrollbar_width): New function.
17674 (xg_get_default_scrollbar_width): Move code to
17675 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17676 (xg_initialize): Call update_theme_scrollbar_width.
17678 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17680 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17682 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17684 * frame.c (make_frame): Call other_buffer_safely instead of
17687 * window.c (temp_output_buffer_show): Call display_buffer with
17688 second argument Vtemp_buffer_show_specifiers and reset latter
17689 immediately after the call.
17690 (Vtemp_buffer_show_specifiers): New variable.
17691 (auto_window_vscroll_p, next_screen_context_lines)
17692 (Vscroll_preserve_screen_position): Remove leading asterisks from
17695 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
17697 Fix minor problems found by GCC 4.6.0 static checking.
17698 * buffer.c (Qclone_number): Remove for now, as it's unused.
17699 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
17700 (record_buffer): Remove unused local.
17701 * frame.c (other_visible_frames, frame_buffer_list): Now static.
17702 (set_frame_buffer_list): Remove; unused.
17703 * frame.h (other_visible_frames): Remove decl.
17704 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
17705 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
17706 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
17708 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
17709 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
17710 Define only if HAVE_GPM.
17711 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
17712 (update_hints_inhibit): Remove; never set. All uses removed.
17713 * widgetprv.h (emacsFrameClassRec): Remove decl.
17714 * window.c (delete_deletable_window): Now returns void, since it
17715 wasn't returning anything.
17716 (compare_window_configurations): Remove unused locals.
17717 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
17718 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
17719 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
17720 the same widths as pointers. This follows up on the 2011-05-06 patch.
17721 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
17722 * xterm.h: Likewise.
17723 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
17725 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
17727 * makefile.w32-in: Update dependencies.
17728 (LISP_H): Add lib/intprops.h.
17730 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
17732 * image.c (gif_load): Add animation frame delay to the metadata.
17733 (syms_of_image): Use DEFSYM. New symbol `delay'.
17735 2011-06-11 Martin Rudalics <rudalics@gmx.at>
17737 * window.c (delete_deletable_window): Re-add.
17738 (Fset_window_configuration): Rewrite to handle dead buffers and
17739 consequently deletable windows.
17740 (window_tree, Fwindow_tree): Remove. Supply functionality in
17742 (compare_window_configurations): Simplify code.
17744 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
17746 * image.c (imagemagick_load_image): Fix type mismatch.
17747 (Fimagemagick_types): Likewise.
17749 * window.h (replace_buffer_in_windows): Declare.
17751 2011-06-11 Martin Rudalics <rudalics@gmx.at>
17753 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
17754 Qclone_number. Remove external declaration of Qdelete_window.
17755 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
17757 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
17758 Run Qbuffer_list_update_hook if allowed.
17759 (Fother_buffer): Rewrite doc-string. Major rewrite for new
17760 buffer list implementation.
17761 (other_buffer_safely): New function.
17762 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
17763 calls to replace_buffer_in_windows and
17764 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
17766 (record_buffer): Inhibit quitting and rewrite using quittable
17767 functions. Run Qbuffer_list_update_hook if allowed.
17768 (Frecord_buffer, Funrecord_buffer): New functions.
17769 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
17770 Move switch-to-buffer to window.el.
17771 (bury-buffer): Move to window.el.
17772 (Vbuffer_list_update_hook): New variable.
17774 * lisp.h (other_buffer_safely): Add prototype in buffer.c
17777 * window.h (resize_frame_windows): Move up in code.
17778 (Fwindow_frame): Remove EXFUN.
17779 (replace_buffer_in_all_windows): Remove prototype.
17780 (replace_buffer_in_windows_safely): Add prototype.
17782 * window.c: Declare Qdelete_window static again. Move down
17783 declaration of select_count.
17784 (Fnext_window, Fprevious_window): Rewrite doc-strings.
17785 (Fother_window): Move to window.el.
17786 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
17787 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
17788 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
17790 (replace_buffer_in_windows): Implement by calling
17791 Qreplace_buffer_in_windows.
17792 (replace_buffer_in_all_windows): Remove with some functionality
17793 moved into replace_buffer_in_windows_safely.
17794 (replace_buffer_in_windows_safely): New function.
17795 (select_window_norecord, select_frame_norecord): Move in front
17796 of run_window_configuration_change_hook. Remove now obsolete
17798 (Fset_window_buffer): Rewrite doc-string.
17799 Call Qrecord_window_buffer.
17800 (keys_of_window): Move binding for other-window to window.el.
17802 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
17804 * dispextern.h (struct image): Replace data member, whose int_val
17805 and ptr_val fields were not used by anything, with a single
17808 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
17809 (gif_clear_image, gif_load, imagemagick_load_image)

18253 last portion of handle_display_prop.
18254 (compute_display_string_pos): Accept additional argument
18255 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18256 value of a `display' property is a "replacing spec".
18257 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18258 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18259 the display property, but just return a value indicating whether
18260 the display property will replace the characters it covers.
18261 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18262 frame_window_p members of struct bidi_it.
18263 (compute_display_string_pos, compute_display_string_end):
18265 (push_it): Accept second argument POSITION, where pop_it should
18266 jump to continue iteration.
18267 (reseat_1): Initialize bidi_it.disp_pos.
18269 * keyboard.c (adjust_point_for_property): Adjust the call to
18270 display_prop_intangible_p to its new signature.
18272 * dispextern.h (struct bidi_it): New member frame_window_p.
18273 (bidi_init_it): Update prototypes.

18275 (compute_display_string_pos, compute_display_string_end):
18276 Declare prototypes.

18280 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18282 Malloc failure behavior now depends on size of allocation.
18283 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18284 * lisp.h: Change signatures accordingly.
18285 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18286 All callers changed. (Bug#8762)
18288 * gnutls.c: Use Emacs's memory allocators.
18289 Without this change, the gnutls library would invoke malloc etc.
18290 directly, which causes problems on non-SYNC_INPUT hosts, and which
18291 runs afoul of improving memory_full behavior. (Bug#8761)
18292 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18293 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18294 xfree instead of the default malloc, realloc, free.
18295 (Fgnutls_boot): No need to check for memory allocation failure,
18296 since xmalloc does that for us.
18298 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18299 * category.c (hash_get_category_set):
18300 * ccl.c (ccl_driver):
18301 * charset.c (Fdefine_charset_internal):
18302 * charset.h (struct charset.hash_index):
18303 * composite.c (get_composition_id, gstring_lookup_cache)
18304 (composition_gstring_put_cache):
18305 * composite.h (struct composition.hash_index):
18306 * dispextern.h (struct image.hash):
18307 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
18308 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

18311 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18312 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18313 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18314 * image.c (make_image, search_image_cache, lookup_image)
18315 (xpm_put_color_table_h):
18316 * lisp.h (struct Lisp_Hash_Table):
18317 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18318 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18319 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18320 * alloc.c (allocate_vectorlike):
18321 Check for overflow in vector size calculations.
18322 * ccl.c (ccl_driver):
18323 Check for overflow when converting EMACS_INT to int.
18324 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18325 need to be updated by these changes.
18326 * fns.c (make_hash_table, maybe_resize_hash_table):
18327 Check for integer overflow with large hash tables.
18328 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18329 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18330 (SXHASH_REDUCE): New macro.
18331 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18332 Use it instead of discarding useful hash info with large hash values.
18333 (sxhash_float): New function.
18334 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18335 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18336 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18337 Rewrite to use FIXNUM_BITS, as this simplifies things.
18338 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18339 Adjust signatures to match updated version of code.
18340 (consing_since_gc): Now EMACS_INT, since a single hash table can
18341 use more than INT_MAX bytes.
18343 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18345 Make it possible to build with GCC-4.6+ -O2 -flto.
18347 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18349 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18351 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18352 Call minibuffer-inactive-mode.
18354 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18356 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18357 Update dependencies.
18359 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18361 * data.c (init_data): Remove code for UTS, this system is not
18364 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18366 Don't force ./temacs to start in terminal mode.
18368 * frame.c (make_initial_frame): Initialize faces in all cases, not
18369 only when CANNOT_DUMP is defined.
18370 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18372 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18374 * dispnew.c (add_window_display_history): Use const for the string
18375 pointer. Remove declaration, not needed.
18377 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18379 Use 'inline', not 'INLINE'.
18380 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18381 * alloc.c, fontset.c (INLINE): Remove.
18382 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18383 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18384 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18385 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18386 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18388 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18390 Make it possible to run ./temacs.
18392 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18393 syms_of_callproc does the same thing. Remove test for
18394 "initialized", do it in the caller.
18395 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18397 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18399 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18400 (read_minibuf): Use get_minibuffer.
18401 (syms_of_minibuf): Use DEFSYM.
18402 (Qmetadata): New var.
18403 * data.c (Qbuffer): Don't make it static.
18404 (syms_of_data): Use DEFSYM.
18406 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18408 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18409 (CCL_CODE_MIN): New macro.
18411 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18413 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18415 * eval.c (Qdebug): Now static.
18416 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18417 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18418 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18420 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18422 * image.c: Various fixes to ImageMagick code comments.
18423 (Fimagemagick_types): Doc fix.
18425 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18427 Minor fixes prompted by GCC 4.6.0 warnings.
18429 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18431 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18432 (x_clipboard_manager_save_all): Move extern decl to ...
18433 * xterm.h: ... here, so that it can be checked for consistency.
18435 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18437 * xselect.c (x_clipboard_manager_save_frame)
18438 (x_clipboard_manager_save_all): New functions.
18439 (Fx_clipboard_manager_save): Lisp function deleted.
18441 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18442 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18444 * xterm.h: Update prototype.
18446 2011-05-28 William Xu <william.xwl@gmail.com>
18448 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18449 exiting (Bug#8239).
18451 2011-05-28 Jim Meyering <meyering@redhat.com>
18453 Avoid a sign-extension bug in crypto_hash_function.
18454 * fns.c (to_uchar): Define.
18455 (crypto_hash_function): Use it to convert some newly-signed
18456 variables to unsigned, to avoid sign-extension bugs. For example,
18457 without this change, (md5 "truc") would evaluate to
18458 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18459 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18460 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18462 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18464 Integer overflow fixes.
18466 * dbusbind.c: Serial number integer overflow fixes.
18467 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18468 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18469 to hold a serial number that is too large for a fixnum.
18470 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18471 Check for serial numbers out of range. Decode any serial number
18472 that was so large that it became a float. (Bug#8722)
18474 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18475 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18476 Use XFASTINT rather than XUINT when numbers are nonnegative.
18477 (xd_append_arg, Fdbus_method_return_internal):
18478 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18479 arguments, check that Lisp number is nonnegative, rather than
18480 silently wrapping negative numbers around. (Bug#8722)
18481 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18484 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18486 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18488 ccl: Add integer overflow checks.
18489 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18490 (IN_INT_RANGE): New macros.
18491 (ccl_driver): Use them to check for integer overflow when
18492 decoding a CCL program. Many of the new checks are whether XINT (x)
18493 fits in int; it doesn't always, on 64-bit hosts. The new version
18494 doesn't catch all possible integer overflows, but it's an
18495 improvement. (Bug#8719)
18497 * alloc.c (make_event_array): Use XINT, not XUINT.
18498 There's no need for unsigned here.
18500 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18501 This follows up to the 2011-05-06 change that substituted uintptr_t
18502 for EMACS_INT. This case wasn't caught back then.
18504 Rework Fformat to avoid integer overflow issues.
18505 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18506 now (part of C89). Include <verify.h>.
18507 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18508 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18509 (Fformat): Avoid the prepass trying to compute sizes; it was only
18510 approximate and thus did not catch overflow reliably. Instead, walk
18511 through the format just once, formatting and computing sizes as we go,
18512 checking for integer overflow at every step, and allocating a larger
18513 buffer as needed. Keep track separately whether the format is
18514 multibyte. Keep only the most-recently calculated precision, rather
18515 than them all. Record whether each argument has been converted to
18516 string. Use EMACS_INT, not int, for byte and char and arg counts.
18517 Support field widths and precisions larger than INT_MAX. Avoid
18518 sprintf's undefined behavior with conversion specifications such as %#d
18519 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18520 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18521 formatting out-of-range floating point numbers with int
18522 formats. (Bug#8668)
18524 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18526 * data.c: Avoid integer truncation in expressions involving floats.
18527 * data.c: Include <intprops.h>.
18528 (arith_driver): When there's an integer overflow in an expression
18529 involving floating point, convert the integers to floating point
18530 so that the resulting value does not suffer from catastrophic
18531 integer truncation. For example, on a 64-bit host (* 4
18532 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18533 Do not rely on undefined behavior after integer overflow.
18535 merge count_size_as_multibyte, parse_str_to_multibyte
18536 * character.c, character.h (count_size_as_multibyte):
18537 Rename from parse_str_to_multibyte; all uses changed.
18538 Check for integer overflow.
18539 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18540 since it's now a duplicate of the other. This is more of
18541 a character than a buffer op, so better that it's in character.c.
18542 * fns.c, print.c: Adjust to above changes.
18544 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18546 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18548 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18550 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18551 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18552 (x_clipboard_manager_save): Now static.
18553 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18555 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18556 (crypto_hash_function): Now static.
18557 Fix pointer signedness problems. Avoid unnecessary initializations.
18559 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18561 * termhooks.h (Vselection_alist): Make it terminal-local.
18563 * terminal.c (create_terminal): Initialize it.
18565 * xselect.c: Support for clipboard managers.
18566 (Vselection_alist): Move to termhooks.h as terminal-local var.
18567 (LOCAL_SELECTION): New macro.
18568 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18569 (symbol_to_x_atom): Remove gratuitous arg.
18570 (x_handle_selection_request, lisp_data_to_selection_data)
18571 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18572 (x_own_selection, x_get_local_selection, x_convert_selection):
18573 New arg, specifying work frame. Use terminal-local Vselection_alist.
18574 (some_frame_on_display): Delete unused function.
18575 (Fx_own_selection_internal, Fx_get_selection_internal)
18576 (Fx_disown_selection_internal, Fx_selection_owner_p)
18577 (Fx_selection_exists_p): New optional frame arg.
18578 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18579 (x_handle_selection_clear): Don't treat other terminals with the
18580 same keyboard specially. Use the terminal-local Vselection_alist.
18581 (x_clear_frame_selections): Use Frun_hook_with_args.
18583 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18585 * xterm.h: Add support for those atoms.
18587 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18589 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18590 (converted_selections, conversion_fail_tag): New global variables.
18591 (x_selection_request_lisp_error): Free the above.
18592 (x_get_local_selection): Remove unnecessary code.
18593 (x_reply_selection_request): Args changed; handle arbitrary array
18594 of converted selections stored in converted_selections.
18595 Separate the XChangeProperty and SelectionNotify steps.
18596 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18597 (x_convert_selection): New function.
18598 (x_handle_selection_event): Simplify.
18599 (x_get_foreign_selection): Don't ignore incoming requests while
18600 waiting for an answer; this will fail when we implement
18601 SAVE_TARGETS, and seems unnecessary anyway.
18602 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18603 (Vx_sent_selection_functions): Doc fix.
18605 2011-05-26 Leo Liu <sdl.web@gmail.com>
18607 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18609 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18611 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18613 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18614 for fringe update if it has periodic bitmap.
18615 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18616 and fringe_bitmap_periodic_p.
18618 * fringe.c (get_fringe_bitmap_data): New function.
18619 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18620 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18621 row. Mark glyph row for fringe update if periodicity changed.
18623 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18624 for fringe update unless it has periodic bitmap.
18626 2011-05-25 Kenichi Handa <handa@m17n.org>
18628 * xdisp.c (get_next_display_element): Set correct it->face_id for
18629 a static composition.

18642 * gnutls.c: Remove unused macros.
18643 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18644 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18645 Remove macros that are defined and never used.
18646 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18648 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18650 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18651 (Fx_get_selection_internal): Minor cleanup.
18652 (Fx_own_selection_internal): Rename arguments for consistency with
18655 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

18677 report_file_error introduced by the change from 2011-05-07.
18679 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18681 * systime.h (Time): Define only if emacs is defined.
18682 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18683 where the include path doesn't have X11/X.h by default. See
18684 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18686 2011-05-20 Kenichi Handa <handa@m17n.org>
18688 * composite.c (find_automatic_composition): Fix previous change.
18690 2011-05-20 Glenn Morris <rgm@gnu.org>
18692 * lisp.mk: New file, split from Makefile.in.
18693 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18694 (shortlisp): Remove.
18695 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18697 2011-05-19 Glenn Morris <rgm@gnu.org>
18699 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18700 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18701 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18702 (lisp): Set the order to that of loadup.el.
18703 (shortlisp): Make it a copy of $lisp.
18704 (SOME_MACHINE_LISP): Remove.
18705 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18706 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18708 2011-05-18 Kenichi Handa <handa@m17n.org>
18710 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18711 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18712 (find_automatic_composition): Mostly rewrite for efficiency.
18714 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18716 * makefile.w32-in: Update dependencies.
18718 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18720 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18721 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18723 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18725 Fix some integer overflow issues, such as string length overflow.
18727 * insdel.c (count_size_as_multibyte): Check for string overflow.
18729 * character.c (lisp_string_width): Check for string overflow.
18730 Use EMACS_INT, not int, for string indexes and lengths; in
18731 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18732 the resulting string length overflows an EMACS_INT; instead,
18733 report a string overflow if no precision given. When checking for
18734 precision exhaustion, use a check that cannot possibly have
18735 integer overflow. (Bug#8675)
18736 * character.h (lisp_string_width): Adjust to new signature.
18738 * alloc.c (string_overflow): New function.
18739 (Fmake_string): Use it. This doesn't change behavior, but saves
18740 a few bytes and will simplify future changes.
18741 * character.c (string_escape_byte8): Likewise.
18742 * lisp.h (string_overflow): New decl.
18744 Fixups, following up to the user-interface timestamp change.
18745 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18746 for UI timestamps, instead of unsigned long.
18747 * msdos.c (mouse_get_pos): Likewise.
18748 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18749 * w32gui.h (Time): Define by including "systime.h" rather than by
18750 declaring it ourselves. (Bug#8664)
18752 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18753 * image.c (clear_image_cache): Likewise.
18755 * term.c (term_mouse_position): Don't assume time_t wraparound.
18757 Be more systematic about user-interface timestamps.
18758 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18759 and sometimes 'EMACS_UINT', to represent these timestamps.
18760 This change causes it to use 'Time' uniformly, as that's what X uses.
18761 This makes the code easier to follow, and makes it easier to catch
18762 integer overflow bugs such as Bug#8664.
18763 * frame.c (Fmouse_position, Fmouse_pixel_position):
18764 Use Time, not unsigned long, for user-interface timestamps.
18765 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18766 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18767 * keyboard.h (last_event_timestamp): Likewise.
18768 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18769 * menu.h (xmenu_show): Likewise.
18770 * term.c (term_mouse_position): Likewise.
18771 * termhooks.h (struct input_event.timestamp): Likewise.
18772 (struct terminal.mouse_position_hook): Likewise.
18773 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18774 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18775 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18776 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18777 what it was before.
18778 * menu.h, termhooks.h: Include "systime.h", for Time.
18780 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18781 Don't assume that the difference between two unsigned long values
18782 can fit into an integer. At this point, we know button_down_time
18783 <= event->timestamp, so the difference must be nonnegative, so
18784 there's no need to cast the result if double-click-time is
18785 nonnegative, as it should be; check that it's nonnegative, just in
18786 case. This bug is triggered when events are more than 2**31 ms
18787 apart (about 25 days). (Bug#8664)
18789 * xselect.c (last_event_timestamp): Remove duplicate decl.
18790 (x_own_selection): Remove needless cast to unsigned long.
18792 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18793 that always fit in int. Use a sentinel instead of a counter, to
18794 avoid a temp and to allay GCC's concerns about possible int overflow.
18795 * frame.h (struct frame): Use int for menu_bar_items_used
18796 instead of EMACS_INT, since it always fits in int.
18798 * menu.c (grow_menu_items): Check for int overflow.
18800 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18802 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18803 Before, the code was not consistent. These values cannot exceed
18804 2**31 - 1 so there's no need to make them unsigned.
18805 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18806 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18807 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18809 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18811 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18812 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18813 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18814 presumably because the widths might not match.
18816 * window.c (size_window): Avoid needless test at loop start.
18818 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18820 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18822 2011-05-12 Drew Adams <drew.adams@oracle.com>
18824 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18826 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18828 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18829 `width' to `bar_area_x' and `bar_area_width', respectively.
18830 (x_scroll_run): Take account of fringe background extension.
18832 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18833 Rename local vars `left' and `width' to `bar_area_x' and
18834 `bar_area_width', respectively.
18835 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18836 background extension.
18838 2011-05-10 Jim Meyering <meyering@redhat.com>
18840 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18842 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18844 * image.c (Finit_image_library): Return t for built-in image types,
18845 like pbm and xbm. (Bug#8640)
18847 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18849 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18851 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18853 * w32console.c (Fset_screen_color): Doc fix.
18854 (Fget_screen_color): New function.
18855 (syms_of_ntterm): Defsubr it.
18857 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18858 unlink the temporary file if Fcall_process didn't create it in the
18860 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18861 child process will be redirected to a file specified with `:file'.
18862 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18863 cue to call_process_cleanup not to close that handle.
18865 2011-05-07 Ben Key <bkey76@gmail.com>
18867 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18868 one of two shell specific rules, either bootstrap-temacs-CMD or
18869 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18870 to the previous implementation of the bootstrap-temacs rule.
18871 The bootstrap-temacs-CMD rule is similar to the previous
18872 implementation of the bootstrap-temacs rule except that it
18873 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18876 These changes, along with some changes to nt/configure.bat,
18877 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18878 earlier fix to add support for --cflags and --ldflags options
18879 that include quotes so that it works whether make uses cmd or
18882 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18884 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18885 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18887 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18888 a string. Handle both cases.
18889 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18890 (Fdbus_register_method): Use Qinvalid_function.
18892 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18894 * makefile.w32-in: Update dependencies.
18895 (LISP_H): Add inttypes.h and stdin.h.
18896 (PROCESS_H): Add unistd.h.
18898 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18900 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18901 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18903 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18905 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18907 * term.c (vfatal): Remove stray call to va_end.
18908 It's not needed and the C Standard doesn't allow it here anyway.
18910 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18911 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18913 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18916 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18918 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18920 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18922 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18924 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18926 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18927 * charset.c (Fdefine_charset_internal): Don't initialize
18928 charset.code_space[15]. The value was garbage, on hosts with
18929 32-bit int (Bug#8600).
18931 * lread.c (read_integer): Be more consistent with string-to-number.
18932 Use string_to_number to do the actual conversion; this avoids
18933 rounding errors and fixes some other screwups. Without this fix,
18934 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18935 (digit_to_number): Move earlier, for benefit of read_integer.
18936 Return -1 if the digit is out of range for the base, -2 if it is
18937 not a digit in any supported base. (Bug#8602)
18939 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18941 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18942 to match comment at start of function. This also removes a
18943 GCC warning about overflow in a 32+64-bit port.
18945 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18947 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18948 Reported by Stefan Monnier in
18949 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18950 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18951 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18953 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18954 (EMACS_UINTPTR): Likewise, with uintptr_t.
18956 * lisp.h: Prefer 64-bit EMACS_INT if available.
18957 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18958 on 32-bit hosts that have 64-bit int, so that they can access
18960 However, temporarily disable this change unless the temporary
18961 symbol WIDE_EMACS_INT is defined.
18963 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18965 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18966 This removes an assumption that EMACS_INT and long are the same
18967 width as pointers. The assumption is true for Emacs porting targets
18968 now, but we want to make other targets possible.
18969 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18970 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18971 In the rest of the code, change types of integers that hold casted
18972 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18973 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18974 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18975 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18976 No need to cast type when ORing.
18977 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18978 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18979 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18980 assume EMACS_INT is the same width as char *.
18981 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18982 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18983 Remove no-longer-needed casts.
18984 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18985 (xg_tool_bar_help_callback, xg_make_tool_item):
18986 Use EMACS_INTPTR to hold an integer
18987 that will be cast to void *; this can avoid a GCC warning
18988 if EMACS_INT is not the same width as void *.
18989 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18990 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18991 (current_message_1, set_message_1):
18992 Use a local to convert to proper width without a cast.
18993 * xmenu.c (dialog_selection_callback): Likewise.
18995 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18996 Also, don't assume VALBITS / RAND_BITS is less than 5,
18997 and don't rely on undefined behavior when shifting a 1 left into
18999 * lisp.h (get_random): Change signature to match.
19001 * lread.c (hash_string): Use size_t, not int, for hash computation.
19002 Normally we prefer signed values; but hashing is special, because
19003 it's better to use unsigned division on hash table sizes so that
19004 the remainder is nonnegative. Also, size_t is the natural width
19005 for hashing into memory. The previous code used 'int', which doesn't
19006 retain enough info to hash well into very large tables.
19007 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19009 * dbusbind.c: Don't possibly lose pointer info when converting.
19010 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19011 Use XPNTR rather than XHASH, so that the high-order bits of
19012 the pointer aren't lost when converting through void *.
19014 * eval.c (Fautoload): Don't double-shift a pointer.
19016 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19018 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19020 * gnutls.c (DEF_GNUTLS_FN):
19021 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19023 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19025 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19028 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19030 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19031 New version that can reserve upto 2GB of heap space.
19033 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19035 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19037 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19039 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19040 `gnutls_certificate_set_x509_key_file'.
19042 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19044 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19045 Update dependencies.
19047 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19049 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19050 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19051 Remove unused parameter `fildes'.
19052 * process.c (read_process_output, send_process): Don't pass it.
19054 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19056 Fix previous change: the library cache is defined in w32.c.
19057 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19058 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19060 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19062 Implement dynamic loading of GnuTLS on Windows.
19064 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19065 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19066 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19069 * gnutls.c (Qgnutls_dll): Define.
19070 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19071 (gnutls_*): Declare function pointers.
19072 (init_gnutls_functions): New function to initialize function pointers.
19073 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19074 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19075 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19076 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19077 (emacs_gnutls_write, emacs_gnutls_read)
19078 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19079 (Fgnutls_available_p): New function.
19080 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19081 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19082 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19084 * image.c: Include w32.h.
19085 (Vimage_type_cache): Delete.
19086 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19087 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19088 (w32_delayed_load): Move to w32.c.
19090 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19092 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19093 (w32_delayed_load): Move from image.c. When loading a library, record
19094 its filename in the :loaded-from property of the library id.
19095 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19096 Initialize and staticpro them.
19097 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19099 * process.c: Include lisp.h before w32.h, not after.
19100 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19101 instead of gnutls_record_check_pending.
19103 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19105 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19107 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19108 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19111 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19113 * xterm.c (x_set_frame_alpha): Do not set property on anything

19136 * sysdep.c (wait_for_termination_1): Make static.
19137 (wait_for_termination, interruptible_wait_for_termination):
19138 Move after wait_for_termination_1.

19150 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19152 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19153 rather than `XVECTOR (FOO)->size'.
19155 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19156 inttypes.h, as a gnulib replacement is used if it not available in
19159 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19161 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19162 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19163 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19165 * coding.c (coding_alloc_by_realloc): Error out if destination
19166 will grow beyond MOST_POSITIVE_FIXNUM.
19167 (decode_coding_emacs_mule): Abort if there isn't enough place in
19168 charbuf for the composition carryover bytes. Reserve an extra
19169 space for up to 2 characters produced in a loop.
19170 (decode_coding_iso_2022): Abort if there isn't enough place in
19171 charbuf for the composition carryover bytes.
19173 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19175 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19176 aborting when %lld or %lll format is passed.
19177 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19178 %llo or %llx format is passed. (Bug#8545)
19180 * window.c (window_scroll_line_based): Use a marker instead of
19181 simple variables to record original value of point. (Bug#7952)
19183 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19184 produced by %s or %c overflows available buffer space. (Bug#8545)
19186 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19188 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19189 (SIZE_MAX): Move defn after all includes, as they might #define it.
19191 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19193 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19195 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19197 * keyboard.c (Qdelayed_warnings_hook): Define.
19198 (command_loop_1): Run `delayed-warnings-hook'
19199 if Vdelayed_warnings_list is non-nil.
19200 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19201 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19203 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19205 * doprnt.c (doprnt): Don't return value smaller than the buffer
19206 size if the message was truncated. (Bug#8545).
19208 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19210 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19211 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19213 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19215 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19217 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19219 * makefile.w32-in: Update dependencies.
19221 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19223 Improve `doprnt' and its usage. (Bug#8545)
19224 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19225 `format_end'. Remove support for %l as a conversion specifier.
19226 Don't use xrealloc. Improve diagnostics when the %l size modifier
19227 is used. Update the commentary.
19229 * eval.c (verror): Simplify calculation of size_t.
19231 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19234 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19236 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19239 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19241 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19242 This makes this file independent of the recent pseudovector change.
19244 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19246 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19248 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19249 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19250 Remove unused local.
19251 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19253 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19254 GCC 4.6.0 optimizes based on type-based alias analysis.
19255 For example, if b is of type struct buffer * and v of type struct
19256 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19257 != &v->size, and therefore "v->size = 1; b->size = 2; return
19258 v->size;" must therefore return 1. This assumption is incorrect
19259 for Emacs, since it type-puns struct Lisp_Vector * with many other
19260 types. To fix this problem, this patch adds a new type struct
19261 vectorlike_header that documents the constraints on layout of vectors
19262 and pseudovectors, and helps optimizing compilers not get fooled
19263 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19264 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19265 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19267 (XSETPVECTYPE): Rewrite in terms of new macro.
19268 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19269 This is a bit clearer, and further avoids the possibility of
19270 undesirable aliasing.
19271 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19272 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19273 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19274 since Lisp_Subr is a special case (no "next" field).
19275 (ASIZE): Now uses header.size rather than size.
19276 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19277 to avoid the hassle of writing XVECTOR (foo)->header.size.
19278 (struct vectorlike_header): New type.
19279 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19280 object, to help avoid aliasing.
19281 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19282 (SUBRP): Likewise, since Lisp_Subr is a special case.
19283 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19284 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19285 (struct Lisp_Hash_Table): Combine first two members into a single
19286 struct vectorlike_header member. All uses of "size" and "next" members
19287 changed to be "header.size" and "header.next".
19288 * buffer.h (struct buffer): Likewise.
19289 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19290 * frame.h (struct frame): Likewise.
19291 * process.h (struct Lisp_Process): Likewise.
19292 * termhooks.h (struct terminal): Likewise.
19293 * window.c (struct save_window_data, struct saved_window): Likewise.
19294 * window.h (struct window): Likewise.
19295 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19296 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19297 * buffer.c (init_buffer_once): Likewise.
19298 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19300 * process.c (Fformat_network_address): Use local var for size,
19303 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19305 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19306 * data.c (atof): Remove decl; no longer used or needed.
19307 (digit_to_number): Move to lread.c.
19308 (Fstring_to_number): Use new string_to_number function, to be
19309 consistent with how the Lisp reader treats infinities and NaNs.
19310 Do not assume that floating-point numbers represent EMACS_INT
19311 without losing information; this is not true on most 64-bit hosts.
19312 Avoid double-rounding errors, by insisting on integers when
19313 parsing non-base-10 numbers, as the documentation specifies.
19314 * lisp.h (string_to_number): New decl, replacing ...
19315 (isfloat_string): Remove.
19316 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19317 (read1): Do not accept +. and -. as integers; this
19318 appears to have been a coding error. Similarly, do not accept
19319 strings like +-1e0 as floating point numbers. Do not report
19320 overflow for integer overflows unless the base is not 10 which
19321 means we have no simple and reliable way to continue.
19322 Break out the floating-point parsing into a new
19323 function string_to_number, so that Fstring_to_number parses
19324 floating point numbers consistently with the Lisp reader.
19325 (digit_to_number): Move here from data.c. Make it static inline.
19326 (E_CHAR, EXP_INT): Remove, replacing with ...
19327 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19328 (string_to_number): New function, replacing isfloat_string.
19329 This function checks for valid syntax and produces the resulting
19330 Lisp float number too. Rework it so that string-to-number
19331 no longer mishandles examples like "1.0e+". Use strtoumax,
19332 so that overflow for non-base-10 numbers is reported only when
19333 there's no portable and simple way to convert to floating point.
19335 * textprop.c (set_text_properties_1): Rewrite for clarity,
19336 and to avoid GCC warning about integer overflow.
19338 * intervals.h (struct interval): Use EMACS_INT for members
19339 where EMACS_UINT might cause problems. See
19340 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19341 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19342 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19344 (offset_intervals): Tell GCC not to worry about length overflow
19345 when negating a negative length.
19347 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19348 (overrun_check_free): Likewise.
19350 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19351 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19354 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19355 (gnutls_make_error): Rename local to avoid shadowing.
19356 (gnutls_emacs_global_deinit): ifdef out; not used.
19357 (Fgnutls_boot): Use const for pointer to readonly storage.
19358 Comment out unused local. Fix pointer signedness problems.
19360 * lread.c (openp): Don't stuff size_t into an 'int'.
19361 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19362 about possible signed overflow.
19364 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19365 (GDK_KEY_g): Don't define if already defined.
19366 (xg_prepare_tooltip): Avoid pointer signedness problem.
19367 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19369 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19370 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19372 * xfns.c (Fx_window_property): Simplify a bit,
19373 to make a bit faster and to avoid GCC 4.6.0 warning.
19374 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19376 * fns.c (internal_equal): Don't assume size_t fits in int.
19378 * alloc.c (compact_small_strings): Tighten assertion a little.
19380 Replace pEd with more-general pI, and fix some printf arg casts.
19381 * lisp.h (pI): New macro, generalizing old pEd macro to other
19382 conversion specifiers. For example, use "...%"pI"d..." rather
19383 than "...%"pEd"...".
19384 (pEd): Remove. All uses replaced with similar uses of pI.
19385 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19386 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19387 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19388 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19389 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19390 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19391 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19393 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19394 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19395 * print.c (safe_debug_print, print_object): Likewise.
19396 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19398 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19399 avoiding the 0 flag, which is not portable.
19400 * process.c (Fmake_network_process): Use pI to avoid cast.
19401 * region-cache.c (pp_cache): Likewise.
19402 * xdisp.c (decode_mode_spec): Likewise.
19403 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19404 behavior on 64-bit hosts with printf arg.
19405 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19406 (x_stop_queuing_selection_requests): Likewise.
19407 (x_get_window_property): Don't truncate byte count to an 'int'
19410 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19411 here, since it parses constructs like leading '-' and spaces,
19412 which are not wanted; and it overflows with large numbers.
19413 Instead, simply match F[0-9]+, which is what is wanted anyway.
19415 * alloc.c: Remove unportable assumptions about struct layout.
19416 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19417 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19418 (allocate_vectorlike, make_pure_vector): Use the new macros,
19419 plus offsetof, to remove unportable assumptions about struct layout.
19420 These assumptions hold on all porting targets that I know of, but
19421 they are not guaranteed, they're easy to remove, and removing them
19422 makes further changes easier.
19424 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19425 This doesn't fix a bug but makes the code clearer.
19426 (string_overrun_cookie): Now const. Use initializers that
19427 don't formally overflow signed char, to avoid warnings.
19428 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19429 can cause Emacs to crash when string overrun checking is enabled.
19430 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19431 multiple of sizeof (EMACS_INT); it need not be, if
19432 alignof(EMACS_INT) < sizeof (EMACS_INT).
19433 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19435 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
19437 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
19439 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19441 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19442 supposed to be handshaking. (Bug#8556)
19443 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19445 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19447 * lisp.h (Qdebug): List symbol.
19448 * eval.c (Qdebug): Restore global linkage.
19449 * keyboard.c (debug-on-event): New variable.
19450 (handle_user_signal): Break into debugger when debug-on-event
19451 matches the current signal symbol.
19453 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19455 * alloc.c (check_sblock, check_string_bytes)
19456 (check_string_free_list): Convert to standard C.
19458 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19460 * w32.c (emacs_gnutls_push): Fix typo.
19462 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19464 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19465 "cast to pointer from integer of different size".
19467 Improve doprnt and its use in verror. (Bug#8545)
19468 * doprnt.c (doprnt): Document the set of format control sequences
19469 supported by the function. Use SAFE_ALLOCA instead of always
19472 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19473 is one byte too soon. Don't use xrealloc; instead xfree and
19476 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19478 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19481 * gnutls.c: Renamed global_initialized to
19482 gnutls_global_initialized. Added internals for the
19483 :verify-hostname-error, :verify-error, and :verify-flags
19484 parameters of `gnutls-boot' and documented those parameters in the
19485 docstring. Start callback support.
19486 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19487 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19488 on error. Return error code.
19489 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19490 (emacs_gnutls_read): Likewise.
19491 (Fgnutls_boot): Return handshake error code.
19492 (emacs_gnutls_handle_error): New function.
19493 (wsaerror_to_errno): Likewise.
19495 * w32.h (emacs_gnutls_pull): Add prototype.
19496 (emacs_gnutls_push): Likewise.
19498 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
19499 (emacs_gnutls_push): Likewise.
19501 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
19503 * process.c (wait_reading_process_output): Check if GnuTLS
19504 buffered some data internally if no FDs are set for TLS
19507 * makefile.w32-in (OBJ2): Add gnutls.$(O).
19508 (LIBS): Link to USER_LIBS.

19513 * xdisp.c (handle_single_display_spec): Rename the
19514 display_replaced_before_p argument into display_replaced_p, to
19515 make it consistent with the commentary. Fix typos in the
19518 * textprop.c (syms_of_textprop): Remove dead code.
19519 (copy_text_properties): Delete obsolete commentary about an
19520 interface that was deleted long ago. Fix typos in the description

19524 to changes in oldXMenu/XMenu.h from 2011-04-16.
19525 <menu_help_message, prev_menu_help_message>: Constify.
19526 (IT_menu_make_room): menu->help_text is now `const char **';

19530 to changes in oldXMenu/XMenu.h from 2011-04-16.
19531 (struct XMenu): Declare `help_text' `const char **'.

19793 ns_descriptor_to_entity that were caused by using free to
19794 deallocate memory blocks that were allocated by xmalloc (via

20011 * font.h (font_close_object): Remove.
20012 * fontset.c (FONTSET_OBJLIST): Remove.
20013 (free_realized_fontset) #if-0 the body, which does nothing.
20014 (face_suitable_for_char_p): #if-0, as it's never called.
20015 * fontset.h (face_suitable_for_char_p): Remove decl.
20016 * xfaces.c (face_at_string_position):
20017 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
20018 since 0 is always ASCII.
20020 * fns.c (weak_hash_tables): Now static.
20022 * fileio.c: Make symbols static if they're not exported.
20023 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

20041 * editfns.c, lisp.h (get_operating_system_release): Remove.
20042 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
20043 worth the hassle of breaking this out.
20045 * xterm.c: Make symbols static if they're not exported.
20046 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

20149 * buffer.c (buffer_count): Remove unused var.
20151 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

20158 * atimer.h (run_all_atimers): Remove; not exported.
20160 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20161 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20162 was inaccessible from Lisp.
20163 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20164 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20166 alloc.c: Import and export fewer symbols, and remove unused items.
20167 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20169 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20170 it's not optimized away by whole-program optimization.

20172 (catchlist, handlerlist, mark_backtrace):
20173 Declare only if BYTE_MARK_STACK.

20182 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20183 (mark_backtrace): Define only if BYTE_MARK_STACK.
20184 * xdisp.c (message_enable_multibyte): Now static.
20186 Declare Lisp_Object Q* variables to be 'static' if not exported.
20187 This makes it easier for human readers (and static analyzers)
20188 to see whether these variables are used from other modules.
20189 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20190 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

20199 Remove decls of unexported vars.
20200 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20202 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20204 Make Emacs functions such as Fatom 'static' by default.
20205 This makes it easier for human readers (and static analyzers)
20206 to see whether these functions can be called from other modules.
20207 DEFUN now defines a static function. To make the function external
20208 so that it can be used in other C modules, use the new macro DEFUE.
20209 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20210 (Finit_image_library):
20211 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20212 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20213 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20214 Remove decls, since these functions are now static.
20215 (Funintern, Fget_internal_run_time): New decls, since these functions
20216 were already external.
20218 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20219 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

20225 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
20226 Mark functions with DEFUE instead of DEFUN,
20227 if they are used in other modules.
20228 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20229 decls for now-static functions.
20230 * buffer.h (Fdelete_overlay): Remove decl.

20240 * image.c (Finit_image_library): New forward static decl.
20241 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20242 * intervals.h (Fprevious_property_change):
20243 (Fremove_list_of_text_properties): Remove decls.
20244 * keyboard.c (Fthis_command_keys): Remove decl.
20245 (Fcommand_execute): New forward static decl.

20261 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
20263 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
20266 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20268 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20269 when at ZV. (Bug#8487)
20271 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20273 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20276 * sound.c (sound_cleanup, alsa_close): Likewise.
20277 * termcap.c (tgetent): Likewise.
20278 * xfns.c (x_default_font_parameter): Likewise.
20279 * xsettings.c (read_and_apply_settings): Likewise.
20281 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20282 (overrun_check_free): Protoize.
20284 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20286 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20287 since callers should never pass a negative size.
20288 Change the signature to match that of plain 'read' and 'write'; see
20289 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20290 * lisp.h: Update prototypes of emacs_write and emacs_read.
20292 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20294 * xdisp.c (redisplay_window): Don't try to determine the character
20295 position of the scroll margin if the window start point w->startp
20296 is outside the buffer's accessible region. (Bug#8468)
20298 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20300 Fix write-region and its subroutines for buffers > 2GB.
20301 * fileio.c (a_write, e_write): Modify declaration of arguments and
20302 local variables to support buffers larger than 2GB.
20303 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20305 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20306 argument, local variables, and return value.
20308 * lisp.h: Update prototypes of emacs_write and emacs_read.
20310 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20312 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20314 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20316 Fix more problems found by GCC 4.6.0's static checks.
20318 * xdisp.c (vmessage): Use a better test for character truncation.
20320 * charset.c (load_charset_map): <, not <=, for optimization,
20321 and to avoid potential problems with integer overflow.
20322 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20323 * casetab.c (set_identity, shuffle): Likewise.
20324 * editfns.c (Fformat): Likewise.
20325 * syntax.c (skip_chars): Likewise.
20327 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20328 This also lets GCC 4.6.0 generate slightly better loop code.
20330 * callint.c (Fcall_interactively): <, not <=, for optimization.
20331 (Fcall_interactively): Count the number of arguments produced,
20332 not the number of arguments given. This is simpler and lets GCC
20333 4.6.0 generate slightly better code.
20335 * ftfont.c: Distingish more carefully between FcChar8 and char.
20336 The previous code passed unsigned char * to a functions like
20337 strlen and xstrcasecmp that expect char *, which does not
20338 conform to the C standard.
20339 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20340 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20341 char * when the C standard requires it.
20343 * keyboard.c (read_char): Remove unused var.
20345 * eval.c: Port to Windows vsnprintf (Bug#8435).
20346 Include <limits.h>.
20347 (SIZE_MAX): Define if the headers do not.
20348 (verror): Do not give up if vsnprintf returns a negative count.
20349 Instead, grow the buffer. This ports to Windows vsnprintf, which
20350 does not conform to C99. Problem reported by Eli Zaretskii.
20351 Also, simplify the allocation scheme, by avoiding the need for
20352 calling realloc, and removing the ALLOCATED variable.
20354 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20356 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20357 But keep the doprint source code for now, as we might revamp it
20358 and use it again (Bug#8435).
20359 * lisp.h (doprnt): Remove.
20360 * Makefile.in (base_obj): Remove doprnt.o.
20361 * deps.mk (doprnt.o): Remove.
20363 error: Print 32- and 64-bit integers portably (Bug#8435).
20364 Without this change, on typical 64-bit hosts error ("...%d...", N)
20365 was used to print both 32- and 64-bit integers N, which relied on
20366 undefined behavior.
20367 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20368 * lisp.h (error, verror): Mark as printf-like functions.
20369 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20370 Report overflow in size calculations when allocating printf buffer.
20371 Do not truncate output string at its first null byte.
20372 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20373 Truncate the output at a character boundary, since vsnprintf does not
20375 * charset.c (check_iso_charset_parameter): Convert internal
20376 character to string before calling 'error', since %c now has the
20378 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20379 overflow when computing char to be passed to 'error'. Do not
20380 pass Lisp_Object to 'error'; pass the integer instead.
20381 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20382 formatted with plain %d.
20384 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20386 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20388 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20390 * xterm.c (x_catch_errors): Remove duplicate declaration.
20392 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20394 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20396 2011-04-10 Jim Meyering <meyering@redhat.com>
20398 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20399 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20400 return ssize_t not "int", and use size_t as the buffer length.
20401 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20402 * gnutls.h: Update declarations.
20403 * process.c (read_process_output): Use ssize_t, to match.
20404 (send_process): Likewise.
20406 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20408 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20410 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20412 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20413 Use unsigned char, to match FcChar8 type definition.
20415 * xterm.c (handle_one_xevent):
20416 * xmenu.c (create_and_show_popup_menu):
20417 * xselect.c (x_decline_selection_request)
20418 (x_reply_selection_request): Avoid type-punned deref of X events.
20420 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20422 Fix some uses of `int' instead of EMACS_INT.
20423 * search.c (string_match_1, fast_string_match)
20424 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20425 (scan_buffer, find_next_newline_no_quit)
20426 (find_before_next_newline, search_command, Freplace_match)

20476 instead of using internal_with_output_to_temp_buffer.
20477 (Qhelp_form_show): New var.
20478 (syms_of_keyboard): Use DEFSYM macro.
20480 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20516 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20518 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20519 This avoids several warnings with gcc -Wstrict-overflow.
20520 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20521 directly, rather than having caller test rule sign. This avoids
20522 some unnecessary tests.
20523 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20524 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20525 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20527 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20528 (xfont_open): Avoid unnecessary tests.
20530 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20532 * composite.h, composite.c (composition_gstring_put_cache):
20533 Use EMACS_INT, not int, for length.
20535 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20536 breaking out part of COMPOSITION_DECODE_RULE.
20537 (COMPOSITION_DECODE_RULE): Use it.
20538 * composite.c (get_composition_id): Remove unused local vars,
20539 by using the new macro.
20541 * textprop.c (set_text_properties_1): Change while to do-while,
20542 since the condition is always true at first.
20544 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20545 (interval_deletion_adjustment): Return unsigned value.
20548 * process.c (list_processes_1, create_pty, read_process_output):

20550 (create_pty): Remove unnecessary "volatile"s.
20551 (Fnetwork_interface_info): Avoid possibility of int overflow.

20564 * print.c (print_error_message): Avoid int overflow.
20566 * font.c (font_list_entities): Redo for clarity,
20567 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20569 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20570 (font_score): Avoid potential overflow in diff calculation.

20573 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20575 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20577 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20578 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20579 can always succeed if overflow has undefined behavior.
20581 * search.c (boyer_moore, wordify): Remove vars set but not used.
20582 (wordify): Omit three unnecessary tests.
20584 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20585 All callers changed. This avoids the need for an unused var.
20587 * casefiddle.c (casify_region): Remove var that is set but not used.
20589 * dired.c (file_name_completion): Remove var that is set but not used.
20591 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20593 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20594 (Finsert_file_contents): Remove unnecessary code checking fd.
20596 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20597 Check for integer overflow on size calculations.
20599 * buffer.c (Fprevious_overlay_change): Remove var that is set
20602 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20603 Remove vars that are set but not used.
20604 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20605 (timer_check_2): Mark vars as initialized.
20607 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20609 * image.c (lookup_image): Remove var that is set but not used.
20610 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20612 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20613 that are set but not used.
20615 * xfns.c (make_invisible_cursor): Don't return garbage
20616 if XCreateBitmapFromData fails (Bug#8410).
20618 * xselect.c (x_get_local_selection, x_handle_property_notify):
20619 Remove vars that are set but not used.
20621 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20622 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20624 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20625 Remove var that is set but not used.
20626 (scroll_bar_windows_size): Now size_t, not int.
20627 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20628 Check for overflow.
20630 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20631 (map_tty_color) [!defined MSDOS]: Likewise.
20633 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20635 * coding.c: Remove vars that are set but not used.
20636 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20637 All callers changed.
20638 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20639 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20640 (decode_coding_charset): Remove vars that are set but not used.
20642 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20643 that is set but not used.
20645 * print.c (print_object): Remove var that is set but not used.
20647 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20648 The gnulib version avoids calling malloc in the usual case,
20649 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20650 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20651 * filelock.c (current_lock_owner): Likewise.
20652 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20653 * sysdep.c: Include allocator.h, careadlinkat.h.
20654 (emacs_no_realloc_allocator): New static constant.
20655 (emacs_readlink): New function.
20656 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20657 ../lib/careadlinkat.h.
20659 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20661 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20662 first non-nil return value).
20664 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20666 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20667 if not defined (Bug#8403).
20669 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20671 * xdisp.c (display_count_lines): Remove parameter `start',
20672 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20673 (get_char_face_and_encoding): Remove parameter `multibyte_p',
20674 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20676 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20677 and thereabouts. All callers changed.
20678 (get_per_char_metric): Remove parameter `f', unused since
20679 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20681 2011-04-02 Jim Meyering <meyering@redhat.com>
20683 do not dereference NULL upon failed strdup
20684 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20685 (ns_get_family): Likewise.
20687 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20689 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20691 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20693 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20696 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20698 Add lexical binding.
20700 * window.c (Ftemp_output_buffer_show): New fun.
20701 (Fsave_window_excursion):
20702 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20704 * lread.c (lisp_file_lexically_bound_p): New function.
20705 (Fload): Bind Qlexical_binding.
20706 (readevalloop): Remove `evalfun' arg.
20707 Bind Qinternal_interpreter_environment.
20708 (Feval_buffer): Bind Qlexical_binding.
20709 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20711 (syms_of_lread): Declare `lexical-binding'.
20713 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20715 * keyboard.c (eval_dyn): New fun.
20716 (menu_item_eval_property): Use it.
20718 * image.c (parse_image_spec): Use Ffunctionp.
20720 * fns.c (concat, mapcar1): Accept byte-code-functions.
20722 * eval.c (Fsetq): Handle lexical vars.
20723 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20724 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20725 (FletX, Flet): Obey lexical binding.
20726 (Fcommandp): Handle closures.
20727 (Feval): New `lexical' arg.
20728 (eval_sub): New function extracted from Feval. Use it almost
20729 everywhere where Feval was used. Look up vars in lexical env.
20731 (Ffunctionp): Move from subr.el.
20732 (Ffuncall): Handle closures.
20733 (apply_lambda): Remove `eval_flags'.
20734 (funcall_lambda): Handle closures and new byte-code-functions.
20735 (Fspecial_variable_p): New function.
20736 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20737 but without exporting it to Lisp.
20739 * doc.c (Fdocumentation, store_function_docstring):
20740 * data.c (Finteractive_form): Handle closures.
20742 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20745 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20747 (exec_byte_code): New function extracted from Fbyte_code to handle new
20748 calling convention for byte-code-functions. Add new byte-codes.
20750 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20752 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20754 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20756 * xdisp.c (redisplay_internal): Fix prototype.
20758 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20760 * xdisp.c (SCROLL_LIMIT): New macro.
20761 (try_scrolling): Use it when setting scroll_limit.
20762 Limit scrolling to 100 screen lines.
20763 (redisplay_window): Even when falling back on "recentering",
20764 position point in the window according to scroll-conservatively,
20765 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20767 (try_scrolling): When point is above the window, allow searching
20768 as far as scroll_max, or one screenful, to compute vertical
20769 distance from PT to the scroll margin position. This prevents
20770 try_scrolling from unnecessarily failing when
20771 scroll-conservatively is set to a value slightly larger than the
20772 window height. Clean up the case of PT below the margin at bottom
20773 of window: scroll_max can no longer be INT_MAX. When aggressive
20774 scrolling is in use, don't let point enter the opposite scroll
20775 margin as result of the scroll.
20776 (syms_of_xdisp) <scroll-conservatively>: Document the
20777 threshold of 100 lines for never-recentering scrolling.
20779 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20781 * dispextern.h (move_it_by_lines):
20782 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20783 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20784 (message_log_check_duplicate): Remove parameters `prev_bol' and
20785 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20786 (redisplay_internal): Remove parameter `preserve_echo_area',
20787 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20789 * indent.c (Fvertical_motion):
20790 * window.c (window_scroll_pixel_based, Frecenter):
20791 Don't pass `need_y_p' to `move_it_by_lines'.
20793 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20795 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20796 steal a few bits to be more compact.
20797 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20798 Remove unneeded casts.
20800 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20802 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20804 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20805 binding" message (bug#7967).
20807 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20809 Fix more problems found by GCC 4.6.0's static checks.
20811 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20812 Remove unused local var.
20814 * editfns.c (Fmessage_box): Remove unused local var.
20816 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20817 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20818 Omit unused local vars.
20819 * window.c (shrink_windows): Omit unused local var.
20820 * menu.c (digest_single_submenu): Omit unused local var.
20821 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20822 Omit unused local var.
20824 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20825 Don't assume string length fits in int.
20826 (keyremap_step, read_key_sequence): Use size_t for sizes.
20827 (read_key_sequence): Don't check last_real_key_start redundantly.
20829 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20830 instead of alloca (Bug#8344).
20832 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20833 (Fbacktrace_frame): Don't assume nframes fits in int.
20835 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20837 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20840 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20842 * cm.c (calccost): Turn while-do into do-while, for clarity.
20844 * keyboard.c (syms_of_keyboard): Use the same style as later
20845 in this function when indexing through an array. This also
20846 works around GCC bug 48267.
20848 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20850 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20852 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20853 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20855 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20856 This avoids undefined behavior on integer overflow, and is a bit
20857 more convenient anyway since it is compared to a size_t variable.
20859 Variadic C functions now count arguments with size_t, not int.
20860 This avoids an unnecessary limitation on 64-bit machines, which
20861 caused (substring ...) to crash on large vectors (Bug#8344).
20862 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20863 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20864 All variadic functions and their callers changed accordingly.
20865 (struct gcpro.nvars): Now size_t, not int. All uses changed.

20870 (funcall_lambda, mark_backtrace): Likewise.
20871 * fns.c (concat): Likewise.
20872 * frame.c (x_set_frame_parameters): Likewise.
20873 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20874 0 if not found, not -1. All callers changed.
20876 * alloc.c (garbage_collect): Don't assume stack size fits in int.

21091 Fix more problems found by GCC 4.5.2's static checks.
21093 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21094 the first time through the loop, since we know p0 < p1 then.
21095 This also avoids a gcc -Wstrict-overflow warning.
21097 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21098 leading to a memory leak, possible in functions like
21099 load_charset_map_from_file that can allocate an unbounded number
21100 of objects (Bug#8318).
21102 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21103 that could (at least in theory) be that large.
21105 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21106 This is less likely to overflow, and avoids undefined behavior if
21107 overflow does occur. All callers changed. Use strtoul to scan

21125 * process.c (Fmake_network_process): Use socklen_t, not int,
21126 where POSIX says socklen_t is required in portable programs.
21127 This fixes a porting bug on hosts like 64-bit HP-UX, where
21128 socklen_t is wider than int (Bug#8277).
21129 (Fmake_network_process, server_accept_connection):
21130 (wait_reading_process_output, read_process_output):
21133 * process.c: Rename or move locals to avoid shadowing.

21145 Include tparam.h instead, since it declares them.
21146 * cm.h (PC): Remove extern decl; tparam.h now does this.
21147 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21148 * terminfo.c: Include tparam.h, to check interfaces.
21149 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21150 (tparam): Adjust signature to match interface in tparam.h;
21151 this removes some undefined behavior. Check that outstring and len
21152 are zero, which they always are with Emacs.
21153 * tparam.h (PC, BC, UP): New extern decls.
21155 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21156 (xftfont_open): Rename locals to avoid shadowing.

21174 (composition_update_it): Mark var as initialized.
21175 (find_automatic_composition): Mark vars as initialized,
21176 with a FIXME (Bug#8290).

21195 Fix pointer signedness.
21196 (alsa_choose_format): Remove unused local var.
21197 (wav_play): Initialize a variable to 0, to prevent undefined
21198 behavior (Bug#8278).
21200 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21202 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21204 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21205 clobbering (Bug#8298).
21206 * sysdep.c (sys_subshell): Likewise.
21207 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21209 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21210 This should get cleaned up, so that child_setup has the
21211 same signature on all platforms.
21213 * callproc.c (call_process_cleanup): Now static.
21214 (relocate_fd): Rename locals to avoid shadowing.
21216 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21218 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21219 not to be necessary, and produces flickering.
21221 2011-03-20 Glenn Morris <rgm@gnu.org>
21223 * config.in: Remove file.
21225 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

21270 Define only if needed.
21272 * unexelf.c (unexec): Name an expression,
21273 to avoid gcc -Wbad-function-cast warning.
21274 Use a different way to cause a compilation error if anyone uses
21275 n rather than nn, a way that does not involve shadowing.
21276 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21278 * deps.mk (unexalpha.o): Remove; unused.

21343 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
21344 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21345 some of which prompt warnings from gcc -Wbad-function-cast.
21346 (Fformat_time_string, Fencode_time, Finsert_char):
21347 (Ftranslate_region_internal, Fformat):

21375 (Fmemory_limit): Cast sbrk's returned value to char *.
21377 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21378 avoids undefined behavior in theory.
21380 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21382 Use functions, not macros, for up- and down-casing (Bug#8254).
21383 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21384 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21385 to use the following functions instead of these macros.
21386 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21387 EMACS_INT, since callers assume the returned value fits in int.
21388 (upcase1): Likewise, for UPCASE_TABLE.
21389 (uppercasep, lowercasep, upcase): New static inline functions.
21390 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21400 (regex_compile, re_match_2_internal): Mark locals as initialized.
21401 (RETALLOC_IF): Define only if needed.
21402 (WORDCHAR_P): Likewise. This one is never needed, but is used
21403 only in a comment talking about a compiler bug, so put inside
21404 the #if 0 of that comment.
21405 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21406 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21432 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21433 New macros, so that the caller can use some names other than
21434 gcpro1, gcpro2, etc.
21435 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21437 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21438 argument, for consistency with GCPRO2_VAR, etc: it is now the
21439 prefix of the variable, not the variable itself. All uses
21441 * dired.c (directory_files_internal, file_name_completion):
21442 Rename locals to avoid shadowing.
21444 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21445 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21446 dired.c's scmp function, had undefined behavior.
21447 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21448 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21449 * buffer.h: ... to here, because these macros use current_buffer,
21450 and the new implementation with inline functions needs to have
21451 current_buffer in scope now, rather than later when the macros
21453 (downcase, upcase1): New static inline functions.
21454 (DOWNCASE, UPCASE1): Reimplement using these functions.
21455 This avoids undefined behavior in expressions like
21456 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21457 from race conditions in accessing the global variables
21458 case_temp1 and case_temp2.
21459 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21460 * lisp.h (case_temp1, case_temp2): Remove their decls.
21461 * character.h (ASCII_CHAR_P): Move from here ...
21462 * lisp.h: ... to here, so that the inline functions mentioned
21463 above can use them.
21465 * dired.c (directory_files_internal_unwind): Now static.
21467 * fileio.c (file_name_as_directory, directory_file_name):
21468 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21470 (file_name_as_directory): Use const pointers when appropriate.
21471 (Fexpand_file_name): Likewise. In particular, newdir might
21472 point at constant storage, so make it a const pointer.
21473 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21474 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21476 (Fset_file_times, Finsert_file_contents, auto_save_error):

21481 to avoid shadowing.
21483 * marker.c (bytepos_to_charpos): Remove; unused.
21485 * lisp.h (verify_bytepos, count_markers): New decls,
21486 so that gcc does not warn that these functions aren't declared.
21488 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21489 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21490 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21491 (copy_text): Remove unused local var.
21493 * filelock.c (within_one_second): Now static.
21494 (lock_file_1): Rename local to avoid shadowing.
21496 * buffer.c (fix_overlays_before): Mark locals as initialized.
21497 (fix_start_end_in_overlays): Likewise. This function should be
21498 simplified by using pointers-to-pointers, but that's a different

21501 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21502 (report_overlay_modification): Rename locals to avoid shadowing.

21507 to suppress a gcc -Wclobbered warning that does not seem to be right.
21508 (MAXPATHLEN): Define only if needed.
21510 * process.c (serial_open, serial_configure): Move decls from here ...
21511 * systty.h: ... to here, so that they can be checked.
21513 * fns.c (get_random, seed_random): Move extern decls from here ...
21514 * lisp.h: ... to here, so that they can be checked.
21516 * sysdep.c (reset_io): Now static.

21525 (describe_map_tree):
21526 Rename locals to avoid shadowing.

21676 1152921504606846976) returns the obviously-bogus value (-948597
21677 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
21678 reports time overflow. See
