3 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
5 (display_line): Set w->region_showing to the value of
6 it->region_beg_charpos, not to -1. This fixes redisplay
7 optimization when cursor is moved up after M->. (Bug#13623)
10 * window.h (struct window): region_showing can no longer be
13 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>

22 Omit first arg TARGET, as it's always '\n'. All callers changed.
24 Clean up read_key_sequence a tiny bit more.
25 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
26 (read_key_sequence): Remove unused locals.
28 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
30 Clean up read_key_sequence a bit; reread active keymaps after first event.

39 set of active keymaps. Recompute the set of keymaps after receiving
40 the first event. Remove GOBBLE_FIRST_EVENT.
41 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
42 * keyboard.h (read_char): Update declaration.
43 * lread.c (read_filtered_event): Adjust call to read_char.

53 * marker.c (set_marker_internal): If desired position is passed
54 as a marker, avoid call to buf_charpos_to_bytepos.
55 * window.c (Fset_window_point): Omit redundant type checking.
56 (Fset_window_start): Likewise. Format comment.
57 (window_scroll_pixel_based): Use set_marker_restricted_both
58 with character and byte positions obtained from an iterator.
59 (Fset_window_configuration): Use set_marker_restricted_both.
60 * xdisp.c (message_dolog): Likewise.
62 2013-02-10 Eli Zaretskii <eliz@gnu.org>
64 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
65 When text lines are longer than window's screen lines, don't move back
66 too far. This speeds up some redisplay operations. (Bug#13675)

73 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
75 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
78 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
80 Minor hashing refactoring.
81 * fns.c (SXHASH_REDUCE): Move to lisp.h.
82 (sxhash_float): Return EMACS_UINT, for consistency with the other
84 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
85 non-static inline function and therefore can't use static vars.
86 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
87 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
88 with the other hash functions.
90 2013-02-09 Eli Zaretskii <eliz@gnu.org>
92 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
93 XXXXXX part of the temporary file pattern is not downcased even
94 when w32-downcase-file-names is non-nil. (Bug#13661)
96 * xdisp.c (decode_mode_spec): Remove handling of %t.

118 * lisp.h (make_uninit_vector): New function.
119 * alloc.c (Fvector, Fmake_byte_code):

135 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
137 * coding.c (Fdefine_coding_system_internal): Use AREF where
138 argument is known to be a vector.
139 * fns.c (Flocale_info): Likewise for ASET.
140 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.

150 updateCollectionBehaviour.
152 * nsterm.m (NEW_STYLE_FS): Remove.
153 (ns_last_use_native_fullscreen): New variable.
154 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.

176 (syms_of_nsterm): Add ns-use-native-fullscreen.
178 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
180 * fileio.c (Qchoose_write_coding_system): Now static.
182 2013-02-04 Eli Zaretskii <eliz@gnu.org>
184 * xdisp.c (window_buffer_changed): region_showing can be negative,
185 which still means region is being displayed.
186 (redisplay_internal): Resurrect code that forced redisplay of the
187 whole window when showing region and the mark has changed.
188 Record the new mark position to allow redisplay optimizations.
189 (display_line): If it->region_beg_charpos is non-zero, set the
190 window's region_showing member to -1. (Bug#13623) (Bug#13626)
192 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
193 not bitfield of 1 bit.
195 2013-02-03 Daniel Colascione <dancol@dancol.org>
197 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
198 daemon mode works on cygw32 when Emacs is installed and not just
201 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
203 Avoid file time stamp bug on MS-Windows (Bug#13149).
204 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
205 as FAT32 doesn't update time stamps when truncating them.
206 Also, check that a file time stamp is not a multiple of 100 ns;
207 this should catch all instances of the problem on MS-Windows,
208 as its native file system resolution is 100 ns or worse, and
209 checking for a non-multiple of 100 ns should impose only a small
210 overhead on systems with ns resolution.
212 2013-02-02 Eli Zaretskii <eliz@gnu.org>
214 Avoid encoding file names on MS-Windows when they need to be run
215 through dostounix_filename.
216 * w32.c (normalize_filename): Accept an additional argument
217 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
218 downcase it even if w32-downcase-file-names is non-nil.
219 (dostounix_filename): Accept an additional argument MULTIBYTE and
220 pass it to normalize_filename.
221 (emacs_root_dir): Adjust.
223 * msdos.h (dostounix_filename): Adjust prototype.
225 * w32.h (dostounix_filename): Adjust prototype.
227 * msdos.c (dostounix_filename): Accept an additional argument and
229 (init_environment): Adjust callers of dostounix_filename.
231 * fileio.c (Ffile_name_directory, file_name_as_directory)
232 (directory_file_name, Fexpand_file_name)
233 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
235 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
237 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
238 variables, as egetenv is case-insensitive for DOS_NT.
240 * dired.c (file_name_completion): Don't call Fdirectory_file_name
241 with an encoded file name.
243 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
244 Adjust calls to dostounix_filename.
246 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
248 * unexw32.c (unexec): Adjust call to dostounix_filename.
250 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
252 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
255 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
258 * callproc.c (Fcall_process): Make sure program name in PATH and
259 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
260 is passed to exec/spawnve, which fails unless the file-name
263 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
264 even if w32-quote-process-args is nil.
266 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
268 Fix timestamp bug when write-region appends nothing (Bug#13149).
269 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
270 the file's time stamp doesn't change if Emacs happens to write nothing
271 to the file, and on a buggy file system this could cause Emacs to
272 incorrectly infer that the file system doesn't have the bug.
273 Avoid this problem by inhibiting the inference in this case.
275 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
277 * window.h (struct window): Convert base_line_number, base_line_pos
278 and column_number_displayed members from Lisp_Object to ptrdiff_t.

287 (wset_column_number_displayed, wset_region_showing): Remove.
288 (window_buffer_changed, mode_line_update_needed, redisplay_internal)

290 (try_window_reusing_current_matrix, try_window_id, display_line)
291 (display_mode_lines, decode_mode_spec): Adjust users.
292 * .gdbinit (pwinx): Do not print sequence_number.
294 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
296 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
297 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
298 * dired.c: Include <fcntl.h>.
299 (open_directory): New function, which uses open and fdopendir
300 rather than opendir. DOS_NT platforms still use opendir, though.

308 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
309 (emacs_readlinkat): New function, with much of the old
310 Ffile_symlink_p, but with an fd argument for speed.
311 It uses readlinkat rather than careadlinkatcwd, so that it
312 need not assume the working directory.
313 (Ffile_symlink_p): Use it.
314 * filelock.c (current_lock_owner): Use emacs_readlinkat
315 rather than emacs_readlink.
316 * lisp.h (emacs_readlinkat): New decl.
317 (READLINK_BUFSIZE, emacs_readlink): Remove.
318 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
319 (emacs_norealloc_allocator, emacs_readlink): Remove.
320 This stuff is moved to fileio.c.
321 * w32.c (fstatat, readlinkat): New functions.
322 (careadlinkat): Don't check that fd == AT_FDCWD.
323 (careadlinkatcwd): Remove; no longer needed.
325 2013-01-31 Glenn Morris <rgm@gnu.org>
327 * fileio.c (choose_write_coding_system): Make it callable from Lisp.

339 (logon_network_drive, stat_worker, symlink, chase_symlinks):
340 Use CharNextExA and CharPrevExA to iterate over file names encoded in
343 * w32.c (w32_get_long_filename, init_environment, readlink):
344 Support file names encoded in DBCS codepages.
345 (readlink): Use the current file-name-coding-system, not the ANSI
346 codepage, to decode and handle targets of symlinks.
348 2013-01-28 Eli Zaretskii <eliz@gnu.org>
350 * w32.c (opendir): Now accepts a 'const char *'.
352 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

374 2013-01-25 Eli Zaretskii <eliz@gnu.org>
376 * w32.c (max_filename_mbslen): New function.
377 (normalize_filename, readdir): Use it to detect locales where ANSI
378 encoding of file names uses a double-byte character set (DBCS).
379 If a DBCS encoding is used, advance by characters using
380 CharNextExA, instead of incrementing a 'char *' pointer.
381 Use _mbslwr instead of _strlwr. (Bug#13515)
383 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
384 request of memory reservation to 1.7GB. (Bug#13065)

407 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
409 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
410 properly. Likewise for obscured.

424 * xdisp.c (message2, message2_nolog): Remove functions.
425 (message3, message3_nolog): Extract nbytes and multibyteness directly
426 from the string. Change all callers.
427 (message3_nolog): Don't set message_enable_multibyte since set_message
428 will reset it anyway.
429 (message1, message1_nolog): Use message3.
430 (vmessage): Use a stack allocated buffer rather than f->message_buf.
431 (with_echo_area_buffer): Remove last two arguments. Update all callers.
432 (set_message): Drop all but the second arg, which has to be a string.

449 * dispnew.c (adjust_frame_message_buffer): Remove function.
451 2013-01-23 Eli Zaretskii <eliz@gnu.org>
453 * w32term.c (w32fullscreen_hook): Account correctly for the screen
454 real estate used for the tool bar and the menu bar.
456 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
458 * insdel.c (prepare_to_modify_buffer): Force redisplay if
459 hidden buffer is prepared to modification (Bug#13164).
461 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>

473 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
474 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
475 (find_first_unchanged_at_end_row, try_window_id): Likewise.
477 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
479 * xdisp.c (mark_window_display_accurate): Simplify the loop
480 assuming that the only one of vchild, hchild or buffer window
481 slots is non-nil. Call mark_window_display_accurate_1 for
482 the leaf windows only.
483 (mark_window_display_accurate_1): Always assume leaf window.
486 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
488 * emacs.c (Qkill_emacs_hook): Now static.
490 * fileio.c (Finsert_file_contents): Simplify.
491 Remove unnecessary assignments and tests.
493 2013-01-21 Eli Zaretskii <eliz@gnu.org>
495 * w32.c (acl_set_file): Don't test for errors unless
496 set_file_security returns FALSE. Avoids spurious errors when
499 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
501 * fileio.c (Finsert_file_contents): Revert code introduced at
502 2013-01-18 in favor of the simpler and generally better fix.
503 Save stack space by removing 'buffer' and reusing 'read_buf'
506 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
508 * lisp.h (eabs): Define unconditionally (Bug#13419).
509 The old "#if !defined (eabs)" was an unnecessary revenant of back
510 when this macro was called "abs". Document 'eabs' better.
512 2013-01-19 Glenn Morris <rgm@gnu.org>
514 * fns.c (Frandom): Doc fix.
516 2013-01-19 Eli Zaretskii <eliz@gnu.org>
518 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
519 segfault when there are lots of overlays.
521 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
522 when there are lots of overlays.
523 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
524 for the details and a way to reproduce.
526 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
528 * fileio.c: Use O_APPEND to append.
529 This corresponds better to the natural interpretation of "append",
530 and avoids the need to open the output file twice, or to invoke
531 lseek when APPEND is neither nil nor a number.
532 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
533 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
534 file possibly twice, and lseeking to its end; this avoids the
535 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
536 at the same time: the combination is never needed and apparently
537 it doesn't work with DOS_NT.
539 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
540 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
542 Allow floating-point file offsets.
543 Problem reported by Vitalie Spinu in
544 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
545 * fileio.c (emacs_lseek): Remove.
546 (file_offset): New function.
547 (Finsert_file_contents, Fwrite_region): Use it.
549 2013-01-19 Chong Yidong <cyd@gnu.org>
551 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
552 aborting on Fsignal (Bug#13289).
554 2013-01-19 Eli Zaretskii <eliz@gnu.org>
556 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
557 set_file_security as failure due to insufficient privileges.
558 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
559 (fstat): Return owner and group like 'stat' and 'lstat' do.
561 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
563 Work around bug in CIFS and vboxsf file systems (Bug#13149).
564 The bug was observed on Ubuntu operating inside a virtual machine,
565 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
566 The workaround introduces a race condition on non-buggy hosts,
567 but it's an unlikely race and anyway there's a nearly identical
568 nearby race that can't be fixed.
569 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
571 (Fwrite_region): Test for file system time stamp bug.
572 (init_fileio): New function.
573 * lisp.h (init_fileio): Declare it.
574 * emacs.c (main): Call it.
576 * fileio.c (Finsert_file_contents): Simplify new diagnostic
577 and make it more consistent with other stat-failure diagnostics.
579 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
581 Fix crash when inserting data from non-regular files.
582 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
583 for the error description produced by valgrind.
584 * fileio.c (read_non_regular): Rename to read_contents.
585 Free Lisp_Save_Value object used to pass parameters.
586 (read_non_regular_quit): Rename to read_contents_quit.
587 (Finsert_file_contents): Redesign internal file reading loop to adjust
588 gap and end positions after each read and so help make_gap to work
589 properly. Do not signal an I/O error too early and so do not leave
590 not yet decoded characters in a buffer, which was the reason of
591 redisplay crash. Use list2 to build return value. Adjust comments.
593 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
595 Close a race when statting and reading files (Bug#13149).
596 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
597 This avoids a race if the file is renamed between stat and open.
598 This race is not the problem originally noted in Bug#13149;
599 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
601 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

640 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
642 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
644 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
645 extraction from any Lisp_Save_Value slot. Add type checking.
646 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
647 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
648 * xselect.c: All users changed.
650 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

668 * fileio.c (do_auto_save_unwind):
669 * gtkutil.c (pop_down_dialog):
670 * keymap.c (map_keymap_char_table_item):
671 * lread.c (load_unwind):

697 (mark_object): Likewise.
698 * editfns.c (save_excursion_save): Pack everything within
699 Lisp_Save_Value and so avoid xmalloc.
700 (save_excursion_restore): Adjust to match new layout. Use free_misc
701 because we do not allocate extra memory any more. Add eassert.
702 * print.c (print_object): New code to print Lisp_Save_Value. Do not
703 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
704 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
705 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

771 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
773 Avoid unnecessary byte position calculation for the gap movement.
774 Since all users of move_gap do CHAR_TO_BYTE for other purposes
775 anyway, all of them should use move_gap_both instead.

777 * insdel.c (move_gap): Remove.
778 (move_gap_both): Add eassert.
779 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

785 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
787 * term.c (init_tty): Use them instead of rolling our own code.
788 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
789 switches from 'signal' to 'pthread_sigmask', which is safer in
790 multithreaded applications.
791 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
792 which has already arranged for that.
793 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

813 left-margin-width, right-margin-width, left-fringe-width,
814 right-fringe-width, scroll-bar-width and buffer-display-count.
815 Use Qstringp for default-directory, buffer-file-name,
816 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
817 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

843 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
844 of (supports :underline (:style wave)). (Bug#13000)

870 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
871 Display the newline glyph more unambiguously.

876 * w32term.c (w32_draw_underwave):
877 * xterm.c (x_draw_underwave): Make underwave look more triangular
878 and also degrade gracefully for small fonts. (Bug#13000)

909 * w32.c (unsetenv): Set up the string passed to _putenv
911 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html

950 (LIBS_GNUSTEP): Define.
951 (LIBES): Add $(LIBS_GNUSTEP).
952 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
954 2012-12-30 Eli Zaretskii <eliz@gnu.org>
956 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
957 continuation glyph on a TTY with an indication of an empty line.
960 2012-12-29 Eli Zaretskii <eliz@gnu.org>
962 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
963 file's SELinux context or ACLs successfully set, nil otherwise.
965 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
967 * w32proc.c (reader_thread): Avoid passing NULL handles to
968 SetEvent and WaitForSingleObject.
970 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
972 Port EXTERNALLY_VISIBLE to Clang 3.2.
973 * conf_post.h (__has_attribute): New macro.
974 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
976 2012-12-27 Glenn Morris <rgm@gnu.org>
978 * cygw32.c (Fcygwin_convert_file_name_to_windows)
979 (Fcygwin_convert_file_name_from_windows): Doc fixes.
981 2012-12-27 Eli Zaretskii <eliz@gnu.org>
983 * fileio.c (file_name_as_directory, directory_file_name):
984 Accept an additional argument MULTIBYTE to indicate whether the input C
985 came from a multibyte or a unibyte Lisp string; all callers
986 adjusted. Don't assume the input string is always multibyte.
988 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
989 don't ENCODE_FILE them, and return a unibyte string if the input
991 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
992 don't assume the input strings will always be multibyte. If the
993 input strings are multibyte, decode strings obtained from C
996 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
998 * lisp.h (toplevel): Add two notices to the comment about
999 defining a new Lisp data type.
1000 * print.c (print_object): If Lisp_Save_Value object's pointer
1001 is the address of a memory area containing Lisp_Objects, try
1003 * alloc.c (valid_lisp_object_p): Adjust comment.
1005 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1007 * keyboard.c (record_asynch_buffer_change): Initialize an event
1008 only if it's really needed.
1009 * frame.h (enum output_method): Remove output_mac member since
1010 it's a leftover from the deleted code.
1011 * frame.c (Fframep): Adjust user here ...
1012 * terminal.c (Fterminal_live_p): ... and here.
1013 * coding.c (Qmac): Now here because it's only used to denote
1014 end-of-line encoding type.
1015 (syms_of_coding): DEFSYM it.
1016 * frame.h (Qmac): Remove duplicated declaration.
1018 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1020 * window.c (select_window_1): Now static, since it's used only here.
1022 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1024 * window.c (window_body_cols): Subtract display margins from the
1025 window body width on TTYs as well. See
1026 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1027 for the original report.
1029 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1031 * xdisp.c (redisplay_window): Remove inner local variable
1032 because the outer shadowed one has the same meaning.
1033 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1035 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1036 (xg_create_tool_bar): Adjust users.
1038 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1040 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1041 * buffer.c (Fget_buffer_create): Use it to set compact field of
1042 struct buffer_text to avoid accessing an uninitialized value
1043 when compact_buffer is called for the first time.
1044 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1045 (Fset_buffer_modified_p): Use buffer_window_count to check
1046 whether the buffer is displayed in some window.
1047 * xdisp.c (message_dolog): Likewise.
1049 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1051 * w32.c (acl_set_file): If setting the file security descriptor
1052 fails, and the new DACL is identical to the existing one, silently
1053 return success. This fixes problems for users backing up their
1054 own files without having the necessary privileges for setting
1055 security descriptors.
1057 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1059 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1060 after WaitForSingleObject returns normally. This expedites reader
1061 thread shutdown when delete_child triggers it.
1062 (reap_subprocess): More accurate commentary for why we call
1063 delete_child only when cp->fd is negative.
1065 * w32.c (sys_close): Do not call delete_child on a subprocess
1066 whose handle is not yet closed. Instead, set its file descriptor
1067 to a negative value, so that reap_subprocess will call
1068 delete_child on that subprocess when its SIGCHLD arrives.
1069 This avoids closing handles used for communications between sys_select
1070 and reader_thread, which doesn't give sys_select a chance to
1071 notice that the process exited and invoke the SIGCHLD handler for
1074 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1076 * nsfns.m (Fns_do_applescript): Run event loop until script has
1077 been executed (Bug#12969).
1078 (ns_run_ascript): Chech as_script for nil, set to nil after
1081 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1083 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1085 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1087 * w32term.c (w32fullscreen_hook): New function.
1088 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1090 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1092 * fileio.c (Finsert_file_contents): Doc fix.
1094 * w32proc.c (new_child, delete_child, find_child_pid): For a
1095 subprocess, consider its slot being in use as long as its process
1096 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1097 slot when a new process is started immediately after killing
1098 another one, without waiting enough time for the first process to
1099 be reaped and resources allocated for it be orderly freed.
1101 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1103 2012-12-21 Chong Yidong <cyd@gnu.org>
1105 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1107 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1109 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1111 * w32.c (get_name_and_id): Always pass NULL as the first argument
1112 of lookup_account_sid. Avoids crashes with UNC file names that
1113 refer to DFS domains, not to specific machine names. (Bug#12621)
1114 Remove now unused argument FNAME; all callers changed.
1115 (get_file_owner_and_group): Remove now unused argument FNAME; all
1118 2012-12-21 Chong Yidong <cyd@gnu.org>
1120 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1121 error for invalid chars, don't check for a nil return value.
1123 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1125 Avoid calls to CHAR_TO_BYTE if byte position is known.
1126 * editfns.c (make_buffer_string_both): Use move_gap_both.
1127 (Fbuffer_string): Use make_buffer_string_both.
1128 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1130 (buf_bytepos_to_charpos): Likewise.
1131 (charpos_to_bytepos): Remove.
1132 * fileio.c (Finsert_file_contents): Use move_gap_both.
1133 * search.c (Freplace_match): Likewise.
1134 * process.c (process_send_region): Likewise. Use convenient
1135 names for byte positions.
1136 * lisp.h (charpos_to_bytepos): Remove prototype.
1137 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1138 * insdel.c (move_gap): Likewise.
1140 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
1142 * xdisp.c (redisplay_internal): Remove now-unused local.
1144 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1146 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1147 (redisplay_internal): Don't bother selecting the frame to get the
1148 proper value of frame-local variables (bug#13225).
1150 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1152 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1153 Rename 4th argument since it may be buffer or string. Adjust comment.
1154 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1156 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1158 * coding.c (Fdetect_coding_region): Do not check start and end with
1159 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1160 (code_convert_region): Likewise.
1162 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1164 * w32.c (acl_get_file, acl_set_file): Run the file name through
1165 map_w32_filename, and resolve any symlinks in the file name, like
1167 (acl_set_file): Call revert_to_self, if any privileges were
1170 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1172 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1173 ($(BLD)/w32.$(O)): Update dependencies.
1175 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1177 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1178 propagate redisplay's scrolling (if any) to the right window.
1179 (redisplay_internal): Use ensure_selected_frame.
1180 (display_mode_lines): Complete last fix.
1181 * window.c (select_window_1): New func, extracted from select_window.
1182 (select_window): Use it.
1183 * window.h (select_window_1): Declare.
1185 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1187 Emulate Posix ACL APIs on MS-Windows.
1188 * w32.c: Include sddl.h and sys/acl.h.
1189 (SDDL_REVISION_1): Define if not already defined.
1190 (g_b_init_get_security_descriptor_dacl)
1191 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
1192 (g_b_init_is_valid_security_descriptor)
1193 (g_b_init_set_file_security): New static flags.

1204 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
1205 (acl_free, acl_get_file, acl_set_file): New functions.
1207 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1209 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1211 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1212 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1213 for some of that bug's symptoms can now cause Emacs to abort.
1214 Remove the workaround.
1215 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1216 The bug that caused SIGCHLD to get lost has been fixed, and the
1217 workaround for it can now cause Emacs to abort.
1219 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1221 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1222 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1223 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1225 2012-12-16 Romain Francoise <romain@orebokech.com>
1227 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1228 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1229 and copy ACL entries of file in addition to SELinux context if set.
1230 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1232 * Makefile.in (LIBACL_LIBS): New macro.
1235 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
1237 * fileio.c (internal_delete_file): Use bool for boolean.
1239 2012-12-15 Eli Zaretskii <eliz@gnu.org>
1241 Fix bug #13079 on MS-Windows with temp files not being deleted.
1242 * w32.h (_child_process): New members input_file and
1244 (register_child): First argument is now pid_t.
1245 (record_infile, record_pending_deletion): New prototypes.
1247 * w32proc.c (new_child): Initialize input_file and
1248 pending_deletion members of the child.
1249 (delete_child): Delete the child's temporary input file, if any,
1250 that is pending deletion.
1251 (register_child): First argument is now pid_t.
1252 (record_infile, record_pending_deletion): New functions.
1253 (reap_subprocess): Fix a typo in DebPrint string.
1254 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1256 * fileio.c (internal_delete_file): Return an int again: non-zero
1257 if delete-file succeeds, zero otherwise.
1259 * lisp.h (internal_delete_file): Adjust prototype.
1261 * callproc.c (Fcall_process): Don't overwrite infile with result
1263 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1264 asynchronous subprocess, record the name of the input file name,
1266 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1267 delete the file, record it as pending deletion when the subprocess
1270 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1272 * editfns.c [HAVE_PWD_H]: Include grp.h.
1274 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1276 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1278 Fix permissions bugs with setgid directories etc. (Bug#13125)
1279 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1280 to mark it as a placeholder. The old value was often wrong.
1281 The only user of this attribute has been changed to use
1282 file-ownership-preserved-p instead, with its new group arg.
1283 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1285 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
1287 * xdisp.c (select_frame_for_redisplay, display_mode_lines):

1290 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1292 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1293 try to get accurate owner and group information from NT file
1294 security APIs. This is to make most callers of 'stat' and
1295 'lstat', which don't need that information, much faster.
1297 * dired.c (Ffile_attributes) [WINDOWSNT]:
1298 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1299 owner and group information from 'lstat'.
1301 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1303 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1304 as that confuses set-auto-coding, so insist on the head-read
1305 returning the full 1024 bytes. Let lseek compute the tail offset;
1306 less work for us. Do not ignore I/O errors when reading the tail.
1308 * xdisp.c: Minor style fixes.
1309 (init_iterator): Hoist assignment out of if-expression.
1310 (markpos_of_region): Callers now test for sign, not for -1.
1312 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
1314 Minor redisplay optimization when the region length is zero.
1315 * xdisp.c (markpos_of_region): New function.
1316 (init_iterator): Do not highlight the region of zero length.
1317 (redisplay_window): Check whether the region is of non-zero length.
1318 (try_cursor_movement): Allow if the region length is zero.
1319 (try_window_reusing_current_matrix, try_window_id): Likewise.
1321 2012-12-13 Eli Zaretskii <eliz@gnu.org>
1323 * search.c (search_buffer): Check the inverse translations of each
1324 character in pattern when the buffer being searched is unibyte.
1327 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1329 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1330 files, fixing a regression from 24.2.
1331 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1333 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1335 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1336 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1337 Remove unnecessary S_ISLNK test, as (contra the comments) this
1338 function can't copy symlinks. Improve quality of error message
1339 when attempting to copy files that are neither regular files nor
1342 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
1344 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

1346 * window.c (Frecenter):
1347 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1348 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1350 2012-12-12 Daniel Colascione <dancol@dancol.org>
1352 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1353 the dumped Emacs is not a sparse file, greatly improving Cygwin
1354 "make bootstrap" performance.
1356 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1358 * inotify.c (inotify_callback): Generate an Emacs event for every
1359 incoming inotify event.
1361 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1363 * xdisp.c (handle_face_prop): Fix logic of computing
1364 it->start_of_box_run_p.
1365 (append_space_for_newline): If the glyph row is R2L, reset the
1366 iterator's end_of_box_run_p flag before prepending the space glyph.
1367 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1368 iterator's start_of_box_run_p flag before prepending the stretch.
1369 (append_glyph, produce_image_glyph, append_composite_glyph)
1370 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1371 left_box_line_p and right_box_line_p flags of the glyph for R2L
1372 glyph rows. (Bug#13011)
1374 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1376 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
1377 if changed buffer is not shown in a window.
1378 * insdel.c (prepare_to_modify_buffer): Likewise.
1379 * window.c (replace_buffer_in_windows_safely): Do nothing
1380 if buffer is not shown in a window.
1381 (Fforce_window_update): Likewise if string or buffer argument
1384 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1386 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1387 encoded_file_name, which is what it is.
1389 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1391 Consistently use marker_position and marker_byte_position.
1392 * fringe.c (Ffringe_bitmaps_at_pos):
1393 * indent.c (Fvertical_motion):
1394 * insdel.c (prepare_to_modify_buffer):
1395 * keyboard.c (make_lispy_position):

1397 (window_scroll_pixel_based, displayed_window_lines)
1398 (Fset_window_configuration):
1399 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
1400 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
1401 Replace direct access to marker fields with calls
1402 to marker_position and/or marker_byte_position.
1404 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
1406 * makefile.w32-in (SIG2STR_H): New macro.
1407 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
1408 ($(BLD)/w32notify.$(O)): Update dependencies.
1410 2012-12-10 Daniel Colascione <dancol@dancol.org>
1412 * w32term.c, keyboard.c: Fix build break in cygw32 by omitting
1413 Windows file notification functionality unless WINDOWSNT.
1415 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1418 * w32fns.c (cache_system_info): Initialize the global hinst
1419 variable here so various initialization calls DTRT.
1421 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1422 (hinst): Remove unneeded extern declaration.
1423 (_start): Remove initialization of above variables; remove
1424 initialization of hinst, as cache_system_info now does that.

1572 * dbusbind.c (Fdbus_init_bus):
1574 * xterm.c (x_term_init):

1585 no longer needed here.
1586 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1587 Move to inside set_time_zone_rule; they don't need file scope any more.
1588 (set_time_zone_rule): Maintain the TZ=value string separately.
1589 (syms_of_editfns): Don't initialize initial_tz;
1590 init_editfns now does it.
1591 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1592 * lisp.h (xputenv): New decl.
1594 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1596 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.

1607 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1609 Simplify get_lim_data.
1610 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1611 Remove USG and vlimit methods; no longer used these days.
1612 Add #error catchall just in case.
1614 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1615 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1616 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1617 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1618 (deleted_pid_list, Fdelete_process, create_process)
1619 (record_child_status_change, handle_child_signal, deliver_child_signal)

1623 (abbr_to_signal): New static function.
1624 (Fsignal_process): Use it to convert signal names to ints.

1635 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1637 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1638 This will cause a production Emacs to dump core instead of
1641 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1643 * frame.c (make_frame): Do not set window's buffer to t.
1644 * window.c (Fsplit_window_internal): Likewise. Previously it was
1645 used to indicate that the window is being set up. Now we use
1646 set_window_buffer for all new windows, so the condition in ...
1647 (Fset_window_buffer): ... is always true and can be removed.
1649 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1651 Convenient macro to check whether the buffer is hidden.
1652 * buffer.h (BUFFER_HIDDEN_P): New macro.

1659 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1660 if the child process is still running. Instead, exit the wait
1661 loop and return zero. (Bug#13086)
1663 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1665 * frame.h (x_char_width, x_char_height): Remove prototypes.

1679 * callproc.c, process.h (record_kill_process):
1680 New function, containing part of the old call_process_kill.
1681 (call_process_kill): Use it.
1682 This does not change call_process_kill's behavior.
1683 * process.c (Fdelete_process): Use record_kill_process to fix a
1684 race condition that could cause Emacs to lose track of a child.
1686 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1688 Avoid code duplication between prev_frame and next_frame.
1689 * frame.c (candidate_frame): New function. Add comment.
1690 (prev_frame, next_frame): Use it. Adjust comment.
1692 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1694 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1695 fails, signal an error instead of continuing with an empty
1697 Encode expanded temp file pattern before passing it to mkstemp or
1700 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1701 Encode the file name before passing it to dostounix_filename, in
1702 case it will downcase it (under w32-downcase-file-names).
1705 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1707 Minor call-process cleanups.
1708 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1709 at the same time as other platforms, to simplify analysis.
1710 No need for fd0_volatile since we have synch_process_fd.
1711 Avoid needless emacs_close; arg is always negative.
1713 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1715 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1718 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1720 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1721 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

1724 (FRAME_SPACE_WIDTH): Remove.
1725 * nsterm.m, w32term.c, xterm.c: Adjust users.
1726 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1727 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1728 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1729 members to a bitfields.
1731 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1733 Don't let call-process be a zombie factory (Bug#12980).
1734 Fixing this bug required some cleanup of the signal-handling code.
1735 As a side effect, this change also fixes a longstanding rare race
1736 condition whereby Emacs could mistakenly kill unrelated processes,
1737 and it fixes a bug where a second C-g does not kill a recalcitrant
1738 synchronous process in GNU/Linux and similar platforms.
1739 The patch should also fix the last vestiges of Bug#9488,
1740 a bug which has mostly been fixed on the trunk by other changes.
1741 * callproc.c, process.h (synch_process_alive, synch_process_death)
1742 (synch_process_termsig, sync_process_retcode):
1743 Remove. All uses removed, to simplify analysis and so that
1744 less consing is done inside critical sections.
1745 * callproc.c (call_process_exited): Remove. All uses replaced
1746 with !synch_process_pid.
1747 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1748 These take the role of what used to be in unwind-protect arg.
1750 (block_child_signal, unblock_child_signal):
1751 New functions, to avoid races that could kill innocent-victim processes.
1752 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1753 (call_process_kill): Record killed processes as deleted, so that
1754 zombies do not clutter up the system. Do this inside a critical
1755 section, to avoid a race that would allow the clutter.
1756 (call_process_cleanup): Fix code so that the second C-g works again
1757 on common platforms such as GNU/Linux.
1758 (Fcall_process): Create the child process in a critical section,
1759 to fix a race condition. If creating an asynchronous process,
1760 record it as deleted so that zombies do not clutter up the system.
1761 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1762 light of these changes. Omit unnecessary call to emacs_close
1763 before failure, as the unwind-protect code does that.
1764 * callproc.c (call_process_cleanup):
1765 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1766 * process.c (record_deleted_pid): New function, containing
1767 code refactored out of Fdelete_process.
1768 (Fdelete_process): Use it.
1769 (process_status_retrieved): Remove. All callers changed to use
1770 child_status_change.
1771 (record_child_status_change): Remove, folding its contents into ...
1772 (handle_child_signal): ... this signal handler. Now, this
1773 function is purely a handler for SIGCHLD, and is not called after
1774 a synchronous waitpid returns; the synchronous code is moved to
1775 wait_for_termination. There is no need to worry about reaping
1776 more than one child now.
1777 * sysdep.c (get_child_status, child_status_changed): New functions.
1778 (wait_for_termination): Now takes int * status and bool
1779 interruptible arguments, too. Do not record child status change;
1780 that's now the caller's responsibility. All callers changed.
1781 Reimplement in terms of get_child_status.
1782 (wait_for_termination_1, interruptible_wait_for_termination):
1783 Remove. All callers changed to use wait_for_termination.
1784 * syswait.h: Include <stdbool.h>, for bool.
1785 (record_child_status_change, interruptible_wait_for_termination):
1787 (record_deleted_pid, child_status_changed): New decls.
1788 (wait_for_termination): Adjust to API changes noted above.
1790 * bytecode.c, lisp.h (Qbytecode): Remove.
1791 No longer needed after 2012-11-20 interactive-p changes.
1793 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1795 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1796 the scroll margin, move point outside the margin. (Bug#13055)
1798 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1800 * gtkutil.c (my_log_handler): New function.
1801 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1803 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1805 * lisp.h (modify_region): Rename to...
1806 (modify_region_1): ...new prototype.
1807 * textprop.c (modify_region): Now static. Adjust users.
1808 * insdel.c (modify_region): Rename to...
1809 (modify_region_1): ...new function to work with current buffer.
1810 Adjust comment and users. Use true and false for booleans.
1812 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1814 * alloc.c (free_save_value): New function.
1815 (safe_alloca_unwind): Use it.
1816 * lisp.h (free_save_value): New prototype.
1817 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1819 (save_excursion_restore): Adjust to match saved data structure.
1820 Use free_save_value to offload some work from GC. Drop obsolete
1823 2012-12-03 Chong Yidong <cyd@gnu.org>
1825 * fileio.c (Vauto_save_list_file_name): Doc fix.
1827 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1829 * w32fns.c: Remove prototype of atof.
1830 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1832 (file_dialog_callback): Make it UINT_PTR.
1834 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1837 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1838 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1841 2012-12-03 Glenn Morris <rgm@gnu.org>
1843 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1845 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1847 Fix xpalloc confusion after memory is exhausted.
1848 * alloc.c (xpalloc): Comment fix.
1849 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1850 and signals an error, do not clear charset_table_size, as
1851 charset_table is still valid.
1852 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1854 Use execve to avoid need to munge environ (Bug#13054).
1855 * callproc.c (Fcall_process):
1856 * process.c (create_process):
1857 Don't save and restore environ; no longer needed.
1858 * callproc.c (child_setup):
1859 Use execve, not execvp, to preserve environ.
1861 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1863 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).

1875 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1877 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1879 * xdisp.c (window_outdated): Remove eassert since it hits
1880 some suspicious corner cases (see Bug#13007 and Bug#13012).

1892 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1894 * callproc.c (Fcall_process): Fix vfork portability problems.
1895 Do not assume that fd[0], count, filefd, and save_environ survive
1896 vfork. Fix bug whereby wrong errno value could be reported for
1897 pipe failure. Some minor cleanups, too, as follows. Move buf and
1898 bufsize to the context where they're needed. Change new_argv to
1899 be of type char **, as this is more convenient and avoids casts.
1900 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1901 Now local constants, not macros.
1903 2012-11-18 Kenichi Handa <handa@gnu.org>
1905 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1906 for the variable "f".
1908 2012-11-13 Kenichi Handa <handa@gnu.org>
1910 * font.c (font_unparse_xlfd): Exclude special characters from the
1911 generating XLFD name.
1913 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1915 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1917 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1919 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1923 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1924 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1925 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1926 * lread.c (readbyte_from_file): Assume EINTR is defined.
1927 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1928 Assume EIO and EAGAIN are defined.
1929 * unexcoff.c (write_segment): Assume EFAULT is defined.
1931 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1933 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1936 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1937 highlighting on the frame was cleared. Prevents assertion
1938 violations when repeatedly clicking on the "Top" link of the
1939 "bread-crumbs" in Info buffers.
1941 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1943 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1945 2012-11-24 Ken Brown <kbrown@cornell.edu>
1947 * keyboard.c (HAVE_MOUSE):
1948 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1949 were always defined.
1951 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1953 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1954 between bpos_covered and bpos_max. This fixes cursor display when
1955 several display strings follow each other.
1957 * .gdbinit (pgx): If the glyph's object is a string, display the
1958 pointer to string data, rather than the value of the string object
1959 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1961 * indent.c (Fvertical_motion): If the starting position is covered
1962 by a display string, return to one position before that, to avoid
1963 overshooting it inside move_it_to. (Bug#12930)
1965 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1967 * frame.h (struct frame): Remove display_preempted member
1968 since all users are dead long ago.
1969 * nsterm.h (struct x_output): Use the only dummy member.
1970 * w32menu.c (pending_menu_activation): Remove since not
1972 (set_frame_menubar): Adjust user.
1973 * w32term.h (struct x_output): Drop outdated #if 0 code.
1974 (struct w32_output): Use bitfields for explicit_parent,
1975 asked_for_visible and menubar_active members.
1976 Drop unused pending_menu_activation member.
1977 * xterm.h (struct x_output): Drop outdated #if 0 code.
1978 Use bitfields for explicit_parent, asked_for_visible,
1979 has_been_visible and net_wm_state_hidden_seen members.
1981 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1983 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1984 of a literal "/". (Bug#12955)
1985 (gl-stamp): Invoke fc.exe directly, not through cmd.
1987 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1989 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1990 * dired.c: Assume HAVE_DIRENT_H.
1991 (NAMLEN): Remove, replacing with ...
1992 (dirent_namelen): New function. All uses changed. Use the GNU macro
1993 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1994 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1995 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1996 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1998 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1999 * ndir.h: Rename to ../nt/inc/dirent.h.
2000 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2001 Do not include <dirent.h>; no longer needed.
2002 * w32.c: Include <dirent.h> rather than "ndir.h".
2004 2012-11-23 Chong Yidong <cyd@gnu.org>
2006 * xftfont.c (xftfont_open): Remove duplicate assignment.
2008 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2010 * alloc.c (Fgarbage_collect): Unblock input after clearing
2011 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2012 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2013 * msdos.c (IT_frame_up_to_date): Use it here...
2014 * w32term.c (w32_frame_up_to_date): ...here...
2015 * xterm.c (XTframe_up_to_date): ...and here...
2016 * nsterm.m (ns_frame_up_to_date): ...but not here.
2017 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2019 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2020 Do not check whether GC is in progress.
2022 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2024 * xdisp.c (window_buffer_changed): New function.
2025 (update_menu_bar, update_tool_bar): Use it to
2026 simplify large 'if' statements.
2027 (redisplay_internal): Generalize commonly used
2028 'tail' and 'frame' local variables.
2030 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2032 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2033 with Windows system header.
2035 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2037 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2038 * alloc.c: Assume unistd.h exists.
2039 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2040 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2041 (getwd) [USG]: Remove; no longer needed.
2042 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2043 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2044 * w32.h (getcwd): Remove decl.
2046 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2048 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2049 Make it set selected_window as well.
2050 (update_tool_bar): Use it.
2052 2012-11-21 Ken Brown <kbrown@cornell.edu>
2054 * emacs.c (main): Set the G_SLICE environment variable for all
2055 Cygwin builds, not just GTK builds. See
2056 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2058 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2060 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2061 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2062 Define for the MSVC compiler.
2064 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2066 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2067 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2068 dostounix_filename. Prevents crashes down the road, because
2069 dostounix_filename assumes it gets a unibyte string.
2070 Reported by Michel de Ruiter <michel@sentient.nl>, see
2071 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2073 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

2077 * lread.c (init_obarray): Set `function' fields to Qnil.
2078 * eval.c (Fcommandp): Ignore Qunbound.
2079 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2080 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2081 Test NILP rather than Qunbound.
2082 (Ffmakunbound): Set to Qnil.
2083 (Fsymbol_function): Never signal an error.
2084 (Finteractive_form): Ignore Qunbound.
2086 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2088 * eval.c (interactive_p): Remove no-longer-used decl.
2090 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2092 * xdisp.c (buffer_shared): Adjust comment.
2093 (buffer_shared_and_changed): New function.
2094 (prepare_menu_bars, redisplay_internal): Use it to
2095 decide whether all windows or frames should be updated.
2096 (window_outdated): New function.
2097 (text_outside_line_unchanged_p, redisplay_window): Use it.
2098 (redisplay_internal): Likewise. Fix indentation.
2100 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2102 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2103 (syms_of_eval): Remove corresponding defsubr.
2104 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2106 2012-11-19 Daniel Colascione <dancol@dancol.org>
2108 * w32fns.c (Fx_file_dialog):
2109 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2110 cygwin_convert_file_name*.
2112 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2113 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2115 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2117 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2119 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2121 * w32select.c: Include w32common.h before w32term.h, so that
2122 windows.h gets included before w32term.h uses some of its
2123 features, see below.
2125 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2127 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2129 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2131 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2133 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2134 (ns_select): Return at once if events are held (Bug#12834).
2136 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2138 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2139 Needed following 2012-10-20 change. (Bug#12902)
2141 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2143 * w32proc.c (waitpid): Remove unused label get_result.
2145 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2147 * makefile.w32-in (SYSWAIT_H): New macro.
2148 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2149 ($(BLD)/sysdep.$(O)): Update dependencies.
2151 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2153 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2154 * callproc.c (relocate_fd): Assume F_DUPFD.
2155 * emacs.c, term.c (O_RDWR): Remove.
2156 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2157 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2158 * nsterm.m: Assume <fcntl.h> exists.
2159 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2160 (create_pty, Fmake_network_process, server_accept_connection)
2161 (wait_reading_process_output, init_process_emacs):
2163 (wait_reading_process_output): Put in a special case for WINDOWSNT
2164 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2165 It's not clear this is needed, but it's a more-conservative change.
2166 (create_process): Assume FD_CLOEXEC.
2167 (create_process, create_pty): Assume O_NOCTTY.
2168 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2169 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2170 Omit if not DOS_NT, since F_GETFL is not defined there.
2171 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2172 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2174 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2175 lack it, since gnulib guarantees this.
2176 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2178 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2180 * w32.c (faccessat): Pretend that directories have the execute bit
2181 set. Emacs expects that, e.g., in files.el:cd-absolute.
2183 * w32proc.c (create_child): Don't clip the PID of the child
2184 process to fit into an Emacs integer, as this is no longer a
2186 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2187 reaping only the process specified by PID argument, if that is
2188 positive. Use PID instead of dead_child to know which process to
2189 reap. Wait for the child to die only if WNOHANG is not in
2191 (sys_select): Don't set dead_child.
2193 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2194 as it is no longer needed.
2196 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2198 (record_child_status_change): Remove the setting of
2199 record_at_most_one_child for the !WNOHANG case.
2201 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2203 Fix problems in ns port found by static checking.
2204 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2205 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2206 not to process group.
2207 (ns_select): Use emacs_write, not write, as that's more robust
2208 in the presence of signals.
2209 (fd_handler:): Check for read errors.
2211 2012-11-16 Glenn Morris <rgm@gnu.org>
2213 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2215 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2217 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2219 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2221 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2222 use the same value of thread handle.
2223 (start_timer_thread): If the timer thread exited (due to error),
2224 clean up by closing the two handles it used. Duplicate the caller
2225 thread's handle here, so it gets duplicated only once, when
2226 launching the timer thread. Set priority of the timer thread, not
2228 (getitimer): Don't duplicate the caller thread's handle here.
2231 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2233 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2236 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2238 Remove no-longer-used pty_max_bytes variable.
2239 * process.c (pty_max_bytes): Remove; unused.
2240 (send_process): Do not set it.
2242 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2244 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2245 Update dependencies.
2247 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2249 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2250 This follows up on the 2012-09-29 patch that removed indirection
2251 for the 'function' field. Reported by Sergey Vinokurov in
2252 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2254 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2256 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2257 different name, as the MS runtime does not have such a function,
2258 and probably never will.) All callers changed. Ignore DIRFD
2259 value if PATH is an absolute file name, to match Posix spec
2260 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2263 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2265 * xdisp.c (echo_area_display, redisplay_internal):
2266 Omit redundant check whether frame_garbaged is set.
2268 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2270 Use faccessat, not access, when checking file permissions (Bug#12632).
2271 This fixes a bug that has been present in Emacs since its creation.
2272 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2273 which must set some sort of record. (Torek's bug report was against
2274 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2275 same common flaw.) See Torek's Usenet posting
2276 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2277 Posted: Fri Apr 8 14:18:56 1983.
2278 * Makefile.in (LIB_EACCESS): New macro.
2280 * callproc.c (init_callproc):
2281 * charset.c (init_charset):
2282 * fileio.c (check_existing, check_executable, check_writable)
2284 * lread.c (openp, load_path_check):
2285 * process.c (allocate_pty):
2287 Use effective UID when checking permissions, not real UID.
2288 * callproc.c (init_callproc):
2289 * charset.c (init_charset):
2290 * lread.c (load_path_check, init_lread):
2291 Test whether directories are accessible, not merely whether they exist.
2292 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2293 * fileio.c (check_existing, check_executable, check_writable)
2295 Use symbolic names instead of integers for the flags, as they're
2297 (check_writable): New arg AMODE. All uses changed.
2298 Set errno on failure.
2299 (Ffile_readable_p): Use faccessat, not stat + open + close.
2300 (Ffile_writable_p): No need to call check_existing + check_writable.
2301 Just call check_writable and then look at errno. This saves a syscall.
2302 dir should never be nil; replace an unnecessary runtime check
2303 with an eassert. When checking the parent directory of a nonexistent
2304 file, check that the directory is searchable as well as writable, as
2305 we can't create files in unsearchable directories.
2306 (file_directory_p): New function, which uses 'stat' on most platforms
2307 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2308 (Ffile_directory_p, Fset_file_times): Use it.
2309 (file_accessible_directory_p): New function, which uses a single
2310 syscall for efficiency.
2311 (Ffile_accessible_directory_p): Use it.
2312 * xrdb.c (file_p): Use file_directory_p.
2313 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2314 * lread.c (openp): When opening a file, use fstat rather than
2315 stat, as that avoids a permissions race. When not opening a file,
2316 use file_directory_p rather than stat.
2317 (dir_warning): First arg is now a usage string, not a format.
2318 Use errno. All uses changed.
2319 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2320 that merely introduced a race.
2321 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2322 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2323 and similarly for the other O_* flags.
2324 * w32.c (sys_faccessat): Rename from sys_access and switch to
2325 faccessat's API. All uses changed.
2326 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2327 (magic_db): Rename from magic_file_p.
2328 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2329 char *, so that we don't have to test for file existence
2330 separately from opening the file for reading. This removes a race
2331 fixes a permission-checking problem, and simplifies the code.
2333 (file_p): Remove; no longer needed.
2335 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2337 Omit glyphs initialization at startup.
2338 * dispnew.c (glyphs_initialized_initially_p): Remove.
2339 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2340 (Fredraw_frame): Move actual code from here...
2341 (redraw_frame): ...to here. Add eassert. Adjust comment.
2342 (Fredraw_display): Use redraw_frame.
2343 * xdisp.c (clear_garbaged_frames): Likewise.
2345 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2347 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2348 passed to pint2str and pint2hrstr to be at most the size of the
2349 frame's decode_mode_spec_buffer. This avoids crashes with very
2350 large values of FIELD_WIDTH argument to decode_mode_spec.
2353 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2355 Fix a race with verify-visited-file-modtime (Bug#12863).
2356 Since at least 1991 Emacs has ignored an mtime difference of no
2357 more than one second, but my guess is that this was to work around
2358 file system bugs that were fixed long ago. Since the race is
2359 causing problems now, let's remove that code.
2360 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2361 whose time stamp is off by no more than a second. Insist that the
2362 file time stamps match exactly.
2364 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2366 * frame.h (struct frame): Convert external_tool_bar member to
2367 1-bit unsigned bitfield.

2369 all users are long dead. Adjust comment on mouse_position_hook.
2371 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>

2382 * xmenu.c (menubar_id_to_frame): Likewise.
2383 * xselect.c (frame_for_x_selection): Likewise.
2384 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2385 (x_window_to_menu_bar): Likewise.
2386 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2388 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2390 * data.c (Qdefalias_fset_function): Now static.
2392 Another tweak to vectorlike_header change.
2393 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2394 Remove, and replace all uses with ...
2395 (next_in_free_list, set_next_in_free_list):
2396 New functions, which respect C's aliasing rules better.
2398 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2400 * window.c (list4i): Rename from 'quad'. All uses changed.
2401 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2403 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2405 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2406 warning about mixing declarations and code in ISO C90.
2408 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2410 * window.c (Fsplit_window_internal): Set combination limit of
2411 new parent window to t iff Vwindow_combination_limit is t;
2412 fixing a regression introduced with the change from 2012-09-22.
2413 (Fset_window_combination_limit): Fix doc-string.
2415 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2417 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2418 amount when the scroll margins are too large. When scrolling
2419 backwards in the buffer, give up if cannot reach point or the
2420 scroll margin within a reasonable number of screen lines.
2421 Fixes point position in window under scroll-up/down-aggressively when
2422 point is positioned many lines beyond the window top/bottom.
2425 * ralloc.c (relinquish): If real_morecore fails to return memory
2426 to the system, don't crash; instead, leave the last heap
2427 unchanged and return. (Bug#12774)
2429 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2431 * lisp.h (AUTOLOADP): New macro.

2436 (Finteractive_form): Simplify.
2437 (Fquo): Don't insist on having at least 2 arguments.
2438 (Qdefalias_fset_function): New var.
2440 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2442 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2444 * nsfont.m (Qcondensed, Qexpanded): New variables.
2445 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2446 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2448 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2450 Fix recently introduced crash on MS-Windows (Bug#12839).
2451 * w32term.h (struct scroll_bar): Use convenient header.
2452 (SCROLL_BAR_VEC_SIZE): Remove.
2453 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2455 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2457 Tweak last vectorlike_header change.
2458 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2459 vectorlike object on the free list. This is introduced to avoid
2460 some (but not all) pointer casting and aliasing problems, see
2461 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2462 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

2466 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2468 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2469 been removed, so remove them here also.
2471 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2473 * doc.c (Fdocumentation): Handle new property
2474 dynamic-docstring-function to replace the old ad-advice-info.
2476 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2478 * fns.c (Qeql, hashtest_eq): Now static.
2480 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2482 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2483 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2484 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

2489 Use same hash function for hashfn_profiler as for hash_string etc.
2490 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2491 * lisp.h (sxhash_combine): New inline function, with the contents
2492 of the old SXHASH_COMBINE.
2493 * profiler.c (hashfn_profiler): Use it, instead of having a
2494 special hash function containing a comparison that always yields 1.
2496 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2498 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2499 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2500 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2503 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2505 * image.c (xpm_make_color_table_h): Fix compiler error because
2506 make_hash_table changed.
2508 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2510 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2512 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2514 Use ad-hoc comparison function for the profiler's hash-tables.
2515 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2516 (make_log): Use them.
2517 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2518 call Fequal any more.

2527 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2528 (hash_lookup, hash_remove_from_table): Move assertion checking of
2529 hashfn result here. Check hash-equality before calling cmpfn.

2531 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
2532 (syms_of_fns): Initialize them.

2539 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2541 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2542 value of w32-scroll-lock-modifier is neither nil nor one of the
2543 known key modifiers. (Bug#12806)
2545 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2547 Shrink struct vectorlike_header to the only size field.
2548 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2550 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2551 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2552 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2553 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2554 information from the vector header. Adjust comment.
2555 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)

2566 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2567 (Fmake_bool_vector): Likewise.
2568 (struct large_vector): New type to represent allocation unit for
2569 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2570 (large_vectors): Change type to struct large_vector.
2571 (allocate_vector_from_block): Simplify.
2572 (PSEUDOVECTOR_NBYTES): Replace with...
2573 (vector_nbytes): ...new function. Adjust users.
2574 (sweep_vectors): Adjust processing of large vectors.
2575 (allocate_vectorlike): Likewise.
2576 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2577 Add easserts. Adjust XSETPVECTYPESIZE usage.
2578 (allocate_buffer): Use BUFFER_PVEC_INIT.
2579 (live_vector_p): Adjust to match large vector.
2580 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2581 * buffer.h (struct buffer): Add next member.
2582 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2584 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2585 * fns.c (internal_equal): Adjust to match enum pvec_type change.

2590 (xvecsize): New command.
2592 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2594 * keyboard.c (event_to_kboard): Do not dereference
2595 frame_or_window field of SELECTION_REQUEST_EVENT
2596 and SELECTION_CLEAR_EVENT events (Bug#12814).
2597 * xterm.h (struct selection_input_event): Adjust comment.
2599 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2601 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2602 such as Scroll Lock, if the respective keys are treated as
2603 function keys, not as modifiers. This avoids destroying non-ASCII
2604 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2606 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2608 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2610 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2612 Restore some duplicate definitions (Bug#12814).
2613 This undoes part of the 2012-11-03 changes. Some people build
2614 with plain -g rather than with -g3, and they need the duplicate
2615 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2616 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2617 Define as macros, as well as as enums or as constants.
2619 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2621 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2622 to keypad keys (Bug#12816).
2624 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2626 Minor adjustments of recently-changed frame functions.
2627 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2628 known to be a frame (we're in the FRAMEP branch).
2629 * lisp.h (Qframep): Remove decl. frame.h declares this.
2630 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2631 since they're meant for Lisp fixnum values.
2633 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2635 * window.c (Fwindow_combination_limit): Revert to the only
2636 required argument and adjust docstring as suggested in
2637 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2638 by Martin Rudalics <rudalics@gmx.at>.
2640 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2642 Widely used frame validity and checking functions.
2643 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

2654 (frame_buffer_list, frame_buffer_predicate): Remove.
2655 * lisp.h (frame_buffer_predicate): Remove prototype.
2656 * buffer.c (Fother_buffer): Use decode_any_frame.
2657 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2658 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2659 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2660 (Fclose_font, Ffont_info): Use decode_live_frame.
2661 * fontset.c (check_fontset_name): Likewise.
2662 * terminal.c (Fframe_terminal): Likewise.
2663 * w32fns.c (check_x_frame): Likewise.
2664 * window.c (Fminibuffer_window, Fwindow_at)
2665 (Fcurrent_window_configuration): Likewise.
2666 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2667 Likewise. Allow zero number of arguments. Adjust docstring.
2668 * dispnew.c (Fredraw_frame): Likewise.
2669 * xfaces.c (frame_or_selected_frame): Remove.
2670 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2671 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2672 (Fframe_face_alist): Use decode_live_frame.
2673 * xfns.c (check_x_frame): Likewise.
2675 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2677 * window.c (quad): New function.
2678 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2679 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2680 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2681 (Fwindow_line_height): Use it.
2682 (Fwindow_fringes): Use list3.
2683 (Fwindow_scroll_bars): Use list4.
2684 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2685 (Fwindow_combination_limit): Allow zero number of arguments.
2687 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2689 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2691 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2692 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2693 file descriptor 2 for standard error. (Bug#12805)
2695 2012-11-05 Chong Yidong <cyd@gnu.org>
2697 * process.c (wait_reading_process_output): Revert previous change.
2699 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2701 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2702 This removes code that has been obsolete since around 1990.
2703 * callproc.c (Fcall_process):
2705 * process.c (create_process):
2706 * term.c (dissociate_if_controlling_tty):
2707 Assume setsid exists.
2708 * callproc.c (child_setup): Assume setpgid exists and behaves as
2709 per POSIX.1-1988 or later.
2710 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2711 * emacs.c (shut_down_emacs):
2712 * sysdep.c (sys_suspend, init_foreground_group):
2713 Assume getpgrp behaves as per POSIX.1-1998 or later.
2714 * msdos.c (setpgrp): Remove.
2715 (tcgetpgrp, setpgid, setsid): New functions.
2716 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2717 * term.c (no_controlling_tty): Remove; unused.
2718 * w32proc.c (setpgrp): Remove.
2719 (setsid, tcgetpgrp): New functions.
2721 Simplify by assuming __fpending.
2722 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2723 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2724 Do not assume that __fpending's result fits in int.
2726 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2728 Remove EMACS_OUTQSIZE+sleep hack.
2729 * dispnew.c (update_frame_1): Remove hack for terminals slower
2730 than 2400 bps, which throttled Emacs by having it sleep.
2731 This code hasn't worked since at least 2007, when the multi-tty stuff
2732 was added, and anyway those old terminals are long dead.
2733 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2734 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2736 Fix data-loss with --version (Bug#9574).
2737 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2738 as we can't assume that emacs_strerror is initialized, and strerror
2739 is good enough here.
2740 (main): Invoke atexit earlier, to catch earlier instances of
2741 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2743 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2745 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2746 (keyDown): Remap keypad keys to X11 virtual key codes.
2748 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2750 Fix data-loss with --batch (Bug#9574).
2751 * emacs.c: Include <close-stream.h>.
2752 (close_output_streams): New function.
2753 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2754 and handles errors appropriately.
2755 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2758 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2759 The symptom is a diagnostic "GLib-WARNING **: In call to
2760 g_spawn_sync(), exit status of a child process was requested but
2761 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2762 waitpid(), so exit status can't be returned." The diagnostic
2763 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2764 The real bug is a race condition between Emacs and glib: Emacs
2765 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2766 so that glib can't find it. Work around the bug by invoking
2767 waitpid only on subprocesses that Emacs itself creates.
2768 * process.c (create_process, record_child_status_change):
2769 Don't use special value -1 in pid field, as the caller now must
2770 know the pid rather than having the callee infer it.
2771 The inference was sometimes incorrect anyway, due to another race.
2772 (create_process): Set new 'alive' member if child is created.
2773 (process_status_retrieved): New function.
2774 (record_child_status_change): Use it.
2775 Accept negative 1st argument, which means to wait for the
2776 processes that Emacs already knows about. Move special-case code
2777 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2778 processes that have already been waited for, by testing and
2779 clearing new 'alive' member.
2780 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2781 now does this internally.
2782 (handle_child_signal): Let record_child_status_change do all
2783 the work, since we do not want to reap all exited child processes,
2784 only the child processes that Emacs itself created.
2785 * process.h (Lisp_Process): New boolean member 'alive'.
2787 Omit duplicate definitions no longer needed with gcc -g3.
2788 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2789 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2790 Define only as macros. There's no longer any need to also define
2791 these symbols as enums or as constants, since we now assume
2792 gcc -g3 when debugging.
2794 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2796 * lisp.mk: Adjust comments to the fact that term/internal is now

2805 for GCC versions before 4.
2806 (emacs_raise): Define to call msdos_fatal_signal.
2808 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2809 iterator when starting in the middle of a display or overlay

2819 * process.c (wait_reading_process_output): Avoid a race condition
2820 with SIGIO delivery (Bug#11536).
2822 2012-11-03 Chong Yidong <cyd@gnu.org>
2824 * buffer.c (cursor_type): Untabify docstring.
2826 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2828 * frame.h (struct frame): Drop can_have_scroll_bars member
2829 which is meaningless for a long time. Adjust comments.

2853 (BACKTRACE_LIMIT_MAX): New macro.
2854 (w32_backtrace): New function.
2855 (emacs_abort): Use w32_backtrace when the user chooses not to

2858 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2860 Window-related stuff cleanup here and there.
2861 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2862 Use decode_any_window.
2863 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2864 * xdisp.c (Fformat_mode_line): Likewise.
2865 * font.c (Ffont_at): Use decode_live_window.

2870 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2871 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2874 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2876 Remove pad from struct input_event.
2877 * termhooks.h (struct input_event): Remove padding field.
2879 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2880 member is never cons for a long time. Adjust comment.
2881 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2882 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2883 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2884 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2886 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2888 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2890 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2892 Fix crash when using Emacs as commit editor for git (Bug#12697).
2893 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2894 and it is configured in conf_post.h.
2895 (Fcall_process): Don't invoke both setsid and setpgid; the former
2896 is enough, if it exists.
2897 * callproc.c (Fcall_process, child_setup):
2898 * process.c (create_process): Use setpgid.
2899 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2901 * dispnew.c (init_display): Initialize the foreground group
2902 if we are running a tty display.
2903 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2904 * lisp.h (init_foreground_group): New decl.
2905 * sysdep.c (inherited_pgroup): New static var.
2906 (init_foreground_group, tcsetpgrp_without_stopping)
2907 (narrow_foreground_group, widen_foreground_group): New functions.
2908 (init_sys_modes): Narrow foreground group.
2909 (reset_sys_modes): Widen foreground group.
2911 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2913 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2915 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2917 * minibuf.c (read_minibuf): Restore current buffer since
2918 choose_minibuf_frame calling Fset_frame_selected_window may
2919 change it (Bug#12766).

2927 * font.c (Ffont_at): If WINDOW is specified and it is not
2928 displaying the current buffer, signal an error.
2930 2012-10-29 Daniel Colascione <dancol@dancol.org>
2932 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2933 In preparation for fixing bug#12739, move these functions from
2936 * coding.h, coding.c: ... to here, and compile them only when
2937 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2938 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2940 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2942 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2943 (timer_loop, getitimer, setitimer): Use it instead of
2944 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2946 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2949 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

2954 (ns_select): Initialize t from last_appdefined_event_data instead
2955 of [last_appdefined_event data1].
2956 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2957 remove last_appdefined_event (Bug#12698).
2959 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2961 * frame.c (x_set_font): Catch internal error.
2963 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2965 Avoid overflow in w32 implementation of interval timers.
2966 When possible, for ITIMER_PROF count only times the main thread
2968 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2969 'volatile ULONGLONG' types. All the other data which was
2970 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2971 (GetThreadTimes_Proc): New typedef.
2972 (w32_get_timer_time): New function, returns a suitable time value
2974 (timer_loop): Enter critical section when accessing ULONGLONG
2975 values of the itimer_data struct, as these accesses are no longer
2976 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2977 Remove unused variable.
2978 (init_timers): Initialize s_pfn_Get_Thread_Times.
2979 (start_timer_thread): Don't assign itimer->caller_thread here.
2980 (getitimer): Assign itimer->caller_thread here.

2986 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2987 mouse movement events if the menu bar is active. This avoids
2988 producing a busy "hour-glass" cursor by Windows if the mouse
2989 pointer is positioned over a tooltip shown for some menu item.
2991 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2993 Don't assume process IDs fit in int.
2994 * emacs.c (shut_down_emacs) [!DOS_NT]:
2995 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2996 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2997 Use pid_t, not int, to store process IDs, as 'int'
2998 is not wide enough on a few platforms (e.g., AIX and IRIX).
3000 2012-10-23 Kenichi Handa <handa@gnu.org>
3002 The following change is to make face-font-rescale-alist work
3003 correctly for non-ASCII fonts.

3028 * frame.c (Fmouse_position, Fmouse_pixel_position):
3029 * xdisp.c (produce_stretch_glyph):
3030 Declare local vars only when they're needed.
3031 This is clearer and avoids a warning on OpenBSD about unused vars.

3033 This is safer, and avoids OpenBSD warnings about unused vars.
3034 * keyboard.c (record_menu_key): Remove unnecessary decl.
3035 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3036 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3037 as our definition clashes with OpenBSD's.
3038 * xfaces.c (load_face_colors, check_lface_attrs)
3039 (get_lface_attributes_no_remap, get_lface_attributes)
3040 (lface_fully_specified_p, x_supports_face_attributes_p)
3041 (tty_supports_face_attributes_p, face_fontset, realize_face)
3042 (realize_x_face, realize_tty_face):
3043 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3044 merely Lisp_Object *. This is more informative and avoids
3045 a warning on OpenBSD about accessing beyond an object's size.
3047 2012-10-20 Chong Yidong <cyd@gnu.org>
3049 * lread.c (Fload): Doc fix (Bug#12592).

3075 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3076 (staticpro): If we run out of staticpro slots, die with an
3077 informative error instead of just calling emacs_abort.
3079 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3081 Fix two flaws reported by Dmitry Antipov.

3203 removed or renamed by some other process immediately after Emacs
3204 writes it but before Emacs stats it. Do not assume that stat (or

3280 Use bool for booleans.
3281 * lread.c (safe_to_load_version): Rename from safe_to_load_p,

3335 Use unsigned for counter where wraparound-on-overflow is desired,
3336 since unsigned is guaranteed to have that behavior and signed is not.
3337 (read_char): Use ptrdiff_t for string length.
3338 (get_input_pending): Remove first argument, since it was always
3339 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3340 and behave as if it had that value. Return new value of
3341 input_pending. All callers changed.
3342 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3343 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3345 * keymap.c (push_key_description): Omit last arg, which was always 1.
3346 All callers changed.
3348 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
3350 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

3366 Don't include termopts.h.
3368 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3370 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3372 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3374 * commands.h (immediate_quit): Remove duplicate decl.
3376 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>

3381 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3383 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3385 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3386 match what GetLastError returns. Explain why the function is
3389 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3390 'is_tooltip_frame', to avoid confusion with its global namesake.
3392 2012-10-08 Daniel Colascione <dancol@dancol.org>
3394 * xdisp.c (start_hourglass): Call w32_note_current_window when
3395 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3396 build that caused Emacs to display the hourglass cursor forever.
3398 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3399 which is broken under remote desktop, calculate the number of
3400 colors available for a display based on the display's number of
3401 planes and number of bits per pixel per plane. (bug#10397).
3403 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3405 * nsfont.m (Vfonts_in_cache): New variable.
3406 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3407 are used. Add cached fonts to Vfonts_in_cache.
3408 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3410 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3412 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3414 (FONT_H): Define after FRAME_H.
3415 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3416 Update dependencies.
3418 * w32term.c: Remove leftover declaration of keyboard_codepage.
3420 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3422 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3423 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3424 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3425 (GLOBAL_SOURCES): Add cygw32.c.

3431 ($(BLD)/w32menu.$(O)):
3432 ($(BLD)/w32proc.$(O)): Add w32common.h.
3434 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3436 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3438 2012-10-08 Daniel Colascione <dancol@dancol.org>
3440 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3441 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3442 accidental message numbering hole. Change other messages to
3445 * w32select.h (HAVE_W32SELECT): Remove.
3447 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3448 w32common.h instead of w32heap.h.
3450 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3451 (get_allocation_unit, get_processor_type, get_w32_major_version)
3452 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3453 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3454 (OS_NT, os_subtype, cache_system_info): Move declarations to
3457 * w32heap.c: Include w32common.h.
3458 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3459 (w32_minor_version, w32_build_number, w32_subtype):
3460 Remove duplicate definitions.
3462 * w32fns.c: Include w32common.h; include w32heap.h only in
3465 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3466 Use `report_file_error' instead of `error' in order to better
3467 inform users of what went wrong. Increase NTGUI_UNICODE file
3468 dialog box file name length to 32k, the maximum allowed by the NT
3471 * w32common.h: New file.
3472 (ROUND_UP, ROUND_DOWN, get_page_size)
3473 (get_allocation_unit, get_processor_type, get_w32_major_version)
3474 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3475 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3476 (OS_NT, os_subtype, cache_system_info): Move here.
3478 * unexw32.c, unexcw.c: Include w32common.h.
3480 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3481 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3482 to call syms_of_w32select.
3484 * cygw32.h: Remove obsolete EXFUN declarations.
3486 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3488 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3489 of w32inevt.o from SOME_MACHINE_OBJECTS.
3491 2012-10-08 Daniel Colascione <dancol@dancol.org>
3493 * image.c: Permanent fix for JPEG compilation issue --- limit
3494 jpeglib `boolean' redefinition to Cygwin builds.
3496 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3498 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3500 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3503 2012-10-08 Daniel Colascione <dancol@dancol.org>
3505 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3506 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3507 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3508 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3509 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3510 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3511 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3512 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3513 now a supported configuration.
3515 * Makefile.in: consolidate image variables into LIBIMAGE; add
3516 W32_OBJ and W32_LIBS. Compile new files.
3519 (_DebPrint) declare tracing facility for W32 debugging. We need
3520 to unify tracing later.
3522 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3523 unconditional use of W32 Unicode functions. Cygwin runs only on
3524 100% Unicode operating systems.
3526 * cygw32.c: New file. Define Cygwin-specific facilities.
3527 (Fcygwin_convert_path_to_windows)
3528 (Fcygwin_convert_path_from_windows): New user functions for
3529 accessing Cygwin path-munging routines.
3531 * cygw32.h: New file.
3532 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3533 UTF-16LE strings temporarily inside non-Lisp-visible string
3536 (w32_strerror): Just what it says on the tin.
3538 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3539 also run for Cygwin; both systems have the same problem with using
3540 GUI facilities in a forked child. Also call syms_of_cygw32,
3541 syms_of_w32select in correct places.
3543 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3544 needs fork-then-exec for daemon launching.
3546 * font.h: Include frame.h.
3548 * image.c: Use the image library cache machinery only when we're
3549 compiling for native WINDOWSNT; Cygwin can use shared libraries
3550 like any other Unixlike system.
3552 * keyboard.c: Clarify a comment regarding the input loop.
3554 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3555 functions directly instead of trying to detect at runtime that our
3556 host operating system supports them. We make this change for two
3557 reasons: Cygwin lacks support for the multibyte character
3558 conversion functions used by the legacy menu code, and Cygwin
3559 never needs to rely on non-Unicode APIs.
3561 * unexw32.c (hinst): Declare extern.
3563 * w32.c: Change header order;
3564 (w32_strerror): Move to w32fns.c because we need it for
3565 non-WINDOWSNT builds.
3567 * w32.h: Add #error macro to make sure we don't include w32.h for
3568 Cygwin builds. Remove w32select declarations.
3570 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3571 w32fns.c. w32console.c is WINDOWSNT-only.
3573 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3574 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3576 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3577 (w32_major_version, w32_minor_version, w32_build_number)
3578 (os_subtype, sound_type): Define here
3579 (w32_defined_color): Make color parameter const for consistency
3580 with other _defined_color functions.
3581 (w32_createwindow): Unconditionally call w32_init_class instead of
3582 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3583 through the code is complex and unnecessary because class
3584 registration is practically free.
3585 (w32_name_of_message): New EMACSDEBUG-only function.
3586 (Fset_message_beep): Move here
3587 (Fx_open_connection): Require that the display name for Windows be
3588 "w32" for consistency, emacsclient disambiguation, and maybe, one
3589 day, multi-window-system support.
3590 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3591 Cygwin files for W32 GUI facilities, since these clearly don't
3592 expect Cygwin names.
3593 (_DebPrint): Define.
3594 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3595 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3596 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3597 (w32_last_error): Remove.
3599 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3601 * w32heap.c (syspage_mask): Declare here.
3602 (cache_system_info): Remove.
3604 * w32inevt.c (faked_key): Define globally, not statically.
3605 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3606 (w32_console_toggle_lock_key): Move to w32fns.c.
3608 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3610 * w32proc.c (_DebPrint): Move to w32fns.c.
3611 * w32select.c: Include string.h, stdio.h for Cygwin.
3612 * w32select.h: New File.
3614 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3616 (w32_message_fd): New variable. Under Cygwin, holds the file
3617 descriptor the system used to tell us about pending thread
3620 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3621 that prevented compilation under non-WINDOWSNT systems.
3623 (w32_initialize): Open /dev/windows and assign it to
3624 w32_message_fd. Provide w32 feature.
3626 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3627 (WM_EMACS_INPUT_READY): add.
3628 (prepend_msg, w32_message_fd): Declare globally.
3631 (keyboard_handle): Use only when WINDOWSNT.
3632 (notify_msg_ready): New function. Posts a message to the main
3633 thread's message queue under CYGWIN, which wakes up the main
3634 thread from select(2) by making the /dev/windows file descriptor
3635 ready. Under WINDOWSNT, it sets an event the same way the old
3638 (post, prepend_msg): Actually call notify_msg_ready instead of
3639 setting the input event directly.
3641 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3643 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3644 but it still has blocs in it, don't return it to the system,
3645 instead of aborting. (Bug#12402)
3647 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3649 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3651 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3652 MAC_OS_X_VERSION_10_6.
3653 (syms_of_nsterm): Remove comment about Panther and above for

3657 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3659 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3660 MAC_OS_X_VERSION_10_4.
3662 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3663 MAC_OS_X_VERSION_10_2.
3665 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3667 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3668 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3670 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3671 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3672 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3673 Remove ns_in_resize check.
3674 (ns_clear_frame_area): Remove resize handle code.
3676 * nsfns.m (ns_in_resize): Remove.
3677 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3678 Remove ns_in_resize check.
3680 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3682 Improve sys_siglist detection.
3683 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3684 defined as a macro, as is done in Solaris.
3685 (sys_siglist_entries): New macro.
3686 (save_strsignal): Use it.
3687 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3688 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3690 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3692 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3693 fullscreen/Fullscreen.
3695 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3696 tobar_height is new.
3698 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3699 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3700 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3701 (windowDidResize:): Check for correct window if old style fullscreen.
3702 Capitalize word in comment. Remove incorrect comment.
3703 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3704 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3705 error in drawing background.
3706 (toggleFullScreen:): Remove comment. Rearrange calls.
3707 Set toolbar values to zero, save old height in tobar_height.
3708 Restore tool bar height when leaving fullscreen.
3709 (canBecomeMainWindow): New function.
3711 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3713 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3715 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3717 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3719 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3720 that time stamps of directories could also be changed.
3721 Don't request the too broad GENERIC_WRITE, only the more restrictive
3722 FILE_WRITE_ATTRIBUTES access rights.
3724 * fileio.c (Fset_file_times): Special-case ignoring errors for
3725 directories only on MSDOS, not on MS-Windows.
3727 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3729 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3731 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3733 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3734 see whether CreateFile failed.
3736 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3738 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3739 to avoid similar races.
3740 * keyboard.c (pending_signals): Now bool, not int.
3742 Port timers to OpenBSD, plus check for timer failures.
3743 OpenBSD problem reported by Han Boetes.
3744 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3746 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3747 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3748 like OpenBSD, which has timer_settime but does not declare it.
3749 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3750 whether to use itimerspec-related primitives. All uses of
3751 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3753 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3755 * profiler.c (handle_profiler_signal): Fix a malloc race
3756 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3758 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3760 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3762 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3764 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3765 consistent with the change in return value of 'safe_strsignal'.
3767 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3769 Prefer plain 'static' to 'static inline' (Bug#12541).
3770 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3771 (bidi_set_sor_type, bidi_push_embedding_level)
3772 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3773 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3774 (bidi_cache_search, bidi_cache_ensure_space)
3775 (bidi_cache_iterator_state, bidi_cache_find)
3776 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3777 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3778 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3779 Now 'static', not 'static inline'.
3781 Count overruns when profiling; change units to ns.
3782 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3783 Give extra weight to samples after overruns, to attempt to count
3784 the time more accurately.
3785 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3786 the underlying primitives nominally do ns.
3787 (Fprofiler_cpu_start): Document the change. Mention that
3788 the sampling intervals are only approximate.
3790 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3792 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3794 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3795 case for the special 0 coding-system.
3797 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3798 (Fmake_overlay): Remove redundant tests.
3799 (fix_start_end_in_overlays): Remove redundant recentering.
3801 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3803 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3804 Update dependencies.
3806 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3808 Fix a malloc race condition involving strsignal.
3809 A signal can arrive in the middle of a malloc, and Emacs's signal
3810 handler can invoke strsignal, which can invoke malloc, which is
3811 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3812 Fix it by altering the signal handler so that it does not invoke
3814 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3815 * process.c (status_message): Use const pointer, in case strsignal
3816 is #defined to safe_strsignal.
3817 * sysdep.c (sys_siglist, init_signals): Always define and
3818 initialize a substitute sys_siglist if the system does not define
3819 one, even if HAVE_STRSIGNAL.
3820 (safe_strsignal): Rename from strsignal. Always define,
3821 using sys_siglist. Return a const pointer.
3822 * syssignal.h (safe_strsignal): New decl.
3823 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3825 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3827 * w32proc.c (timer_loop): Fix code that waits for timer
3828 expiration, to avoid high CPU usage.
3830 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3832 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3833 (sweep_weak_table): Remove redundant prototypes.
3835 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3837 * emacs.c: Move the inclusion of TERM_HEADER after including
3838 windows.h on WINDOWSNT. This avoids compilation problems with
3841 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3843 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3844 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3845 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3846 as the previous version used 'void *'.
3848 * ralloc.c (ROUNDUP): Fix last change.
3849 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3852 * w32proc.c <disable_itimers>: New static flag.
3853 (init_timers): Initialize it to zero, after creating the critical
3854 sections used by the timer threads.
3855 (term_timers): Set to 1 before deleting the critical sections.
3856 (getitimer, setitimer): If disable_itimers is non-zero, return an
3857 error indication without doing anything. Reported by Fabrice
3858 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3859 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3861 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3864 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3865 term_ntproc after all the other bookkeeping, to get timers working
3866 as long as possible.
3868 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3870 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3871 Suggested by Juri Linkov in
3872 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3874 Prefer plain 'static' to 'static inline' (Bug#12541).
3875 With static functions, modern compilers inline pretty well by
3876 themselves; advice from programmers often hurts as much as it helps.
3877 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3878 this change shrinks the text size of the Emacs executable by 1.1%
3879 without affecting CPU significantly in my benchmark.
3880 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
3881 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

3960 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3962 Revert the FOLLOW-SYMLINKS change for file-attributes.
3963 Doing it right would require several changes to Tramp, and there's
3964 not enough time to get that tested before the freeze today.
3965 * dired.c (directory_files_internal, Ffile_attributes):
3968 * frame.c (x_report_frame_params): Port better to wider ints.
3969 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3970 or that pointers can be printed in 15 decimal digits.

4008 (check_memory_limits): Adjust prototypes of real_morecore and
4009 __morecore to receive argument of type ptrdiff_t. Use size_t for

4089 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
4091 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
4093 * w32.h (init_timers, term_timers): Add prototypes.
4095 2012-09-30 Kenichi Handa <handa@gnu.org>
4097 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
4098 to the buffer relocation which may be caused by ccl_driver.

4171 (profiler_cpu_running): Now of that enum type, not bool.
4172 All uses changed to store the new value.
4173 (handle_profiler_signal): Rename from sigprof_handler_1,
4174 for consistency with other handlers. Do not check whether
4175 cpu_log is a hash-table if garbage collecting, since it
4176 doesn't matter in that case.
4177 (deliver_profiler_signal): Rename from sigprof_handler,
4178 for consistency with other handlers.
4179 (setup_cpu_timer): New function, with much of what used to be in
4180 Fprofiler_cpu_start. Check for out-of-range argument.
4181 Prefer timer_settime if available, and prefer
4182 thread cputime clocks, then process cputime clocks, then
4183 monotonic clocks, to the old realtime clock. Use make_timeval
4184 to round more-correctly when falling back to setitimer.
4185 (Fprofiler_cpu_start): Use it.
4186 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4187 Don't assume that passing NULL as the 2nd argument of setitimer
4188 is the same as passing a pointer to all-zero storage.
4189 Ignore SIGPROF afterwards.
4190 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4191 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4192 non-fatal signal handlers. Ignore SIGPROF on startup.
4193 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4194 in profiler.c, since sysdep.c now uses it.
4196 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
4197 Suggested by Eli Zaretskii in
4198 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

4208 * profiler.c (record_backtrace, sigprof_handler_1):
4209 * alloc.c (Fgarbage_collect):
4210 * eval.c (interactive_p, Fsignal, eval_sub, Ffuncall, Fbacktrace)
4211 (Fbacktrace_frame): Adjust accordingly.
4213 2012-09-28 Glenn Morris <rgm@gnu.org>
4215 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
4216 (Frun_hook_with_args_until_failure): Doc fixes.
4218 2012-09-28 Eli Zaretskii <eliz@gnu.org>
4220 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
4221 Qautomatic_redisplay and change the symbol name. All users changed.

4234 * Makefile.in (LIB_TIMER_TIME): New macro.
4236 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
4237 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
4240 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
4242 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.

4246 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
4248 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
4250 * character.h (MAYBE_UNIFY_CHAR): Remove.
4251 * charset.c, charset.h (maybe_unify_char): Now static.
4252 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4253 Since this stuff is now private to charset.c, there's no need for
4254 a public macro and no need to inline by hand.
4256 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
4257 Stefan Monnier <monnier@iro.umontreal.ca>
4258 Juanma Barranquero <lekktu@gmail.com>

4283 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4285 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4287 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4289 Prefer POSIX timers if available.
4290 They avoid a race if the timer is too close to the current time.
4291 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4292 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4293 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4295 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4297 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
4298 CHAR_STRING_ADVANCE.
4299 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
4300 STRING_CHAR_ADVANCE.
4302 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4304 Move Vlibrary_cache to emacs.c and reset before dumping.
4306 * lisp.h (reset_image_types): Declare.
4307 [WINDOWSNT] (Vlibrary_cache): Declare.
4309 * image.c (reset_image_types): New function.
4311 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
4312 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
4313 (Fdump_emacs): Reset Vlibrary_cache and image_types.

4316 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
4318 * w32.h (Vlibrary_cache): Do not declare.
4320 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4322 * w32proc.c (sys_signal): Handle all signals defined by the
4323 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4324 handlers for signals supported by Windows. Don't override
4325 term_ntproc as the handler for SIGABRT.
4326 (sigaction): Rewrite to call sys_signal instead of duplicating its
4328 (sys_kill): Improve commentary.
4330 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4331 consistency with a signature of a signal handler. All callers
4333 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4334 install term_ntproc as a signal handler for SIGABRT, as that
4335 should be done by the dumped Emacs.
4337 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4339 * w32select.c (term_w32select): Protect against repeated
4340 invocation by setting clipboard_owner to NULL after calling
4343 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
4344 and term_ntproc to their modified signatures.
4346 * character.c (char_string, string_char): Remove calls to
4347 MAYBE_UNIFY_CHAR. See the discussion starting at
4348 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4351 2012-09-25 Chong Yidong <cyd@gnu.org>
4353 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4355 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4357 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4358 when encountering an unknown bytecode.
4360 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4362 image.c, indent.c: Use bool for booleans.
4363 * dispextern.h (struct image_type): Members valid_p, load, init
4364 now return bool, not int. All uses changed.
4365 * image.c: Omit unnecessary static decls.
4366 (x_create_bitmap_mask, x_build_heuristic_mask):
4367 Return void, not int, since callers don't care about the return value.

4398 2012-09-24 Chong Yidong <cyd@gnu.org>
4400 * chartab.c (Fset_char_table_default): Obsolete function removed.
4402 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4404 Move pid_t related decls out of lisp.h.
4405 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4406 (interruptible_wait_for_termination):
4407 Move these decls from lisp.h to syswait.h, since they use pid_t.
4408 Needed on FreeBSD; see Herbert J. Skuhra in
4409 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4410 * callproc.c: Include syswait.h.

4430 Use bool for boolean.
4431 * gtkutil.c (xg_update_frame_menubar):

4456 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4458 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4459 fatal_error_backtrace.
4461 * w32proc.c (sys_kill): Undo last change: don't do anything when
4462 invoked to deliver SIGABRT to our own process. This is now
4463 handled by emacs_raise.
4465 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4467 * w32term.c (w32_read_socket): Remove leftover reference to
4468 interrupt_input_pending.
4470 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4472 Do not use SA_NODEFER.
4473 Problem reported by Dani Moncayo in
4474 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4476 * sysdep.c (emacs_abort): Do not reset signal handler.
4477 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4478 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4479 wanted even on POSIXish hosts, and it doesn't work on Windows.
4481 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4483 * xterm.c (x_term_init): Call fixup_locale before and after calling
4484 gtk_init (Bug#12392).
4486 2012-09-23 Chong Yidong <cyd@gnu.org>
4488 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4489 Vdynamic_library_alist.
4491 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4492 (Fgnutls_available_p): Caller changed.
4494 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4495 (Flibxml_parse_xml_region): Likewise.
4497 * dispextern.h (struct image_type): Remove arg from init function.
4499 * image.c (Finit_image_library, lookup_image_type)
4500 (define_image_type): Remove now-unneeded second arg.
4501 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4502 (init_tiff_functions, init_gif_functions, init_svg_functions):
4503 Arglist and w32_delayed_load calling convention changed.
4504 (gs_type): Remove init_gs_functions; there is no such function.
4505 (valid_image_p, make_image): Fix caller to lookup_image_type.
4507 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4509 Simplify and avoid signal-handling races (Bug#12471).
4511 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4512 Avoid recursive loop if there's a fatal error in the function itself.
4513 * atimer.c (pending_atimers):
4514 * blockinput.h: Don't include "atimer.h"; no longer needed.
4515 (interrupt_input_pending): Remove. All uses removed.
4516 pending_signals now counts both atimers and ordinary interrupts.
4517 This is less racy than having three separate pending-signal flags.
4518 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4520 Rename from their upper-case counterparts BLOCK_INPUT,
4521 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4522 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4523 This makes it easier to access volatile variables more accurately.
4524 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4525 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4526 that's more reliable if the code is buggy and sets
4527 interrupt_input_blocked to a negative value. All uses changed.
4528 * atimer.c (deliver_alarm_signal):
4529 Remove. No need to deliver this to the parent; any thread can
4530 handle this signal now. All uses replaced by underlying handler.
4531 * atimer.c (turn_on_atimers):
4532 * dispnew.c (handle_window_change_signal):
4533 * emacs.c (handle_danger_signal):
4534 * keyboard.c (kbd_buffer_get_event):
4535 Don't reestablish signal handler; not needed with sigaction.
4536 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4538 Rework to avoid unnecessary accesses to volatile variables.
4539 (UNBLOCK_INPUT_TO): Now a function.
4540 (totally_unblock_input, unblock_input): New decls.
4541 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4542 (init_data): Remove. Necessary stuff now done in init_signal.
4543 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4544 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4545 (fatal_error_code): Remove; no longer needed.
4546 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4547 it doesn't always backtrace. All uses changed. No need to reset
4548 signal to default, since sigaction and/or die does that for us now.
4549 Use emacs_raise (FOO), not kill (getpid (), FOO).
4550 (main): Check more-accurately whether we're dumping.
4551 Move fatal-error setup to sysdep.c
4552 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4553 * gtkutil.c (xg_get_file_name, xg_get_font):
4554 Remove no-longer-needed signal-mask manipulation.
4555 * keyboard.c, process.c (POLL_FOR_INPUT):
4556 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4557 * keyboard.c (read_avail_input): Remove.
4558 All uses replaced by gobble_input.
4559 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4560 (kbd_buffer_store_event_hold, gobble_input):
4561 (record_asynch_buffer_change) [USABLE_SIGIO]:
4562 (store_user_signal_events):
4563 No need to mess with signal mask.
4564 (gobble_input): If blocking input and there are terminals, simply
4565 set pending_signals to 1 and return. All hooks changed to not
4566 worry about whether input is blocked.
4567 (process_pending_signals): Clear pending_signals before processing
4568 them, in case a signal comes in while we're processing.
4569 By convention callers now test pending_signals before calling us.
4570 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4571 New functions, to support changes to blockinput.h.
4572 (handle_input_available_signal): Now extern.
4573 (reinvoke_input_signal): Remove. All uses replaced by
4575 (quit_count): Now volatile, since a signal handler uses it.
4576 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4577 All callers changed. Block SIGINT only if not already blocked.
4578 Clear sigmask reliably, even if Fsignal returns, which it can.
4579 Omit unnecessary accesses to volatile var.
4580 (quit_throw_to_read_char): No need to restore sigmask.
4581 * keyboard.c (gobble_input, handle_user_signal):
4582 * process.c (wait_reading_process_output):
4583 Call signal-handling code rather than killing ourselves.
4584 * lisp.h: Include <float.h>, for...
4585 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4586 (pending_signals): Now volatile.
4587 (syms_of_data): Now const if IEEE floating point.
4588 (handle_input_available_signal) [USABLE_SIGIO]:
4589 (terminate_due_to_signal, record_child_status_change): New decls.
4590 * process.c (create_process): Avoid disaster if memory is exhausted
4591 while we're processing a vfork, by tightening the critical section
4593 (send_process_frame, process_sent_to, handle_pipe_signal)
4594 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4596 (send_process): No need for setjmp/longjmp any more, since the
4597 SIGPIPE stuff is now gone. Instead, report an error if errno
4599 (record_child_status_change): Now extern. PID and W are now args.
4600 Return void, not bool. All callers changed.
4601 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4602 Remove. All uses removed. This bug should be fixed now in a
4604 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4605 and record the child status change directly. This avoids the
4606 need to futz with the signal mask.
4607 (process_fatal_action): Move here from emacs.c.
4608 (emacs_sigaction_flags): New function, containing
4609 much of what used to be in emacs_sigaction_init.
4610 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4611 caught by emacs, to make races less likely.
4612 (deliver_process_signal): Rename from handle_on_main_thread.
4614 (BACKTRACE_LIMIT_MAX): Now at top level.
4615 (thread_backtrace_buffer, threadback_backtrace_pointers):
4617 (deliver_thread_signal, deliver_fatal_thread_signal):
4618 New functions, for more-accurate delivery of thread-specific signals.
4619 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4620 (deliver_arith_signal): Handle in this thread, not
4621 in the main thread, since it's triggered by this thread.
4622 (maybe_fatal_sig): New function.
4623 (init_signals): New arg DUMPING so that we can be more accurate
4624 about whether we're dumping. Caller changed.
4625 Treat thread-specific signals differently from process-general signals.
4626 Block all signals while handling fatal error; that's safer.
4627 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4629 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4630 Ignore SIGPIPE unless batch.
4631 (emacs_backtrace): Output backtrace for the appropriate thread,
4632 which is not necessarily the main thread.
4633 * syssignal.h: Include <stdbool.h>.
4634 (emacs_raise): New macro.
4635 * xterm.c (x_connection_signal): Remove; no longer needed
4636 now that we use sigaction.
4637 (x_connection_closed): No need to mess with sigmask now.
4638 (x_initialize): No need to reset SIGPIPE handler here, since
4639 init_signals does this for us now.
4641 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4643 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4644 background rect may be larger (Bug#12245).
4646 2012-09-23 Chong Yidong <cyd@gnu.org>
4648 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4650 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4652 * .gdbinit: Just stop at fatal_error_backtrace.
4653 See Stefan Monnier's request in
4654 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4655 Remove no-longer-used query of system type.
4657 2012-09-22 Chong Yidong <cyd@gnu.org>
4659 * search.c (Freplace_match): Doc fix (Bug#12325).
4661 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4663 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4664 (Fline_end_position): Doc fix.
4666 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4668 2012-09-22 Chong Yidong <cyd@gnu.org>
4670 * dispextern.h (struct image_type): Add new slot, storing a type
4671 initialization function.
4673 * image.c (define_image_type): Call the image initializer function
4674 if it is defined. Arguments and return value changed.
4675 (valid_image_p, make_image): Callers changed.
4676 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4677 (gif_type, imagemagick_type, svg_type, gs_type):
4678 Add initialization functions.
4679 (Finit_image_library): Call lookup_image_type.
4680 (CHECK_LIB_AVAILABLE): Macro deleted.
4681 (lookup_image_type): Call define_image_type here, rather than via
4682 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4683 (syms_of_image): Move define_image_type calls for xbm_type and
4684 pbm_type to lookup_image_type.
4686 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4688 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4689 'idle_timers' from here ...
4690 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4691 lists, to avoid infloops when the timer does something stupid,
4692 like reinvoke itself with the same or smaller time-out.
4695 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4697 * window.c (Fsplit_window_internal): Handle only Qt value of
4698 Vwindow_combination_limit separately.
4699 (Qtemp_buffer_resize): New symbol.
4700 (Vwindow_combination_limit): New default value.
4703 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4705 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4706 the new overlay string. (Bug#10159)
4708 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4710 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4711 or that fprintf is async-signal-safe. POSIX doesn't require
4714 2012-09-22 Chong Yidong <cyd@gnu.org>
4716 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4719 2012-09-22 Kenichi Handa <handa@gnu.org>
4721 * composite.c (composition_reseat_it): Handle the case that a
4722 grapheme cluster is not covered by a single font (Bug#12352).
4724 2012-09-21 Chong Yidong <cyd@gnu.org>
4726 * image.c (define_image_type): Avoid adding duplicate types to
4727 image_types (Bug#12463). Suggested by Jörg Walter.
4729 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4731 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4732 (print_load_command_name): Add case LC_DATA_IN_CODE.
4733 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4735 2012-09-21 Glenn Morris <rgm@gnu.org>
4737 * eval.c (Frun_hook_with_args_until_success)
4738 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4740 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4742 * fileio.c (Ffile_selinux_context): Only call freecon when
4743 lgetfilecon succeeded.
4744 (Fset_file_selinux_context): Likewise. (Bug#12444)
4746 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4748 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4749 reordering, locate the cursor by calling set_cursor_from_row; if
4750 that fails, clear the desired glyph matrix before returning a
4751 failure indication to the caller. Fixes leaving garbled display
4752 when fast scrolling with a down-key. (Bug#12403)
4753 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4754 scrolling through multibyte text.
4756 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4758 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4759 calling mark_vectorlike since that's the one that marks the window.
4760 (mark_discard_killed_buffers): Mark the final cdr.
4761 * window.h (struct window): Move prev/next_buffers to the
4762 non-standard fields.
4763 * window.c (make_window): Initialize prev/next_buffers manually.
4765 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4767 Omit unused arg EXPECTED from socket hooks.
4768 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4769 * nsterm.m (ns_term_init):
4770 * termhooks.h (struct terminal.read_socket_hook):
4771 * w32inevt.c (w32_console_read_socket):
4772 * w32term.c (w32_read_socket):
4773 * xterm.c (XTread_socket):
4774 Omit unused arg EXPECTED. All callers changed.
4775 (store_user_signal_events): Return void, not int, since callers no
4776 longer care about the return value. All uses changed.
4778 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4780 * w32gui.h (XParseGeometry): Do not declare.
4782 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4784 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4785 Ignore 'expected'. See Eli Zaretskii in
4786 <http://bugs.gnu.org/12471#8> (last line).
4788 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4789 (XParseGeometry): Now static. Substitute extremal values for
4790 values that are out of range.
4792 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4794 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4796 * nsfns.m (XParseGeometry): Remove.
4797 (Fx_create_frame): Call x_set_offset to correctly interpret
4798 top_pos in geometry.
4800 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4801 (Fx_parse_geometry): If there is a space in string, call
4802 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4804 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4806 * search.c (scan_buffer): Use character positions in calls to
4807 region_cache_forward and region_cache_backward, not byte
4808 positions. (Bug#12196)
4810 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4811 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4813 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4814 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4815 emacs_blocked_malloc, now deleted.
4817 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4819 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4820 The workaround was for improving performance on Solaris 2.4, but
4821 is getting in the way now. Emacs will still work if someone is
4822 still running Solaris 2.4 in a museum somewhere; Sun dropped
4823 support for Solaris 2.4 in 2003.
4824 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4825 * process.c (create_process) [HAVE_WORKING_VFORK]:
4826 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4827 since Emacs no longer uses vfork on that platform.
4829 2012-09-17 Glenn Morris <rgm@gnu.org>
4831 * emacs.c: Use COPYRIGHT.
4833 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4835 Remove configure's --without-sync-input option (Bug#12450).
4836 When auditing signal-handling in preparation for cleaning it up,
4837 I found that SYNC_INPUT has race conditions and would be a real
4838 pain to fix. Since it's an undocumented and deprecated
4839 configure-time option, now seems like a good time to remove it.
4840 Also see <http://bugs.gnu.org/11080#16>.
4841 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4842 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4843 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4844 (malloc_hysteresis):
4845 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4846 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4847 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4848 (dont_register_blocks, bytes_used_when_reconsidered)
4849 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4850 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4851 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4852 Remove. All uses removed.
4853 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4854 implementation, one that depends on whether the new macro
4855 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4857 * atimer.c (run_timers, handle_alarm_signal):
4858 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4859 (handle_async_input, process_pending_signals)
4860 (handle_input_available_signal, init_keyboard):
4861 * nsterm.m (ns_read_socket):
4862 * process.c (wait_reading_process_output):
4863 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4864 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4866 * xterm.c (XTread_socket):
4868 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4869 * eval.c (handling_signal): Remove. All uses removed.
4870 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4871 All uses replaced with the SYNC_INPUT version.
4872 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4874 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4877 * font.c (Ffont_shape_gstring): Remove unused local.
4879 2012-09-16 Glenn Morris <rgm@gnu.org>
4881 * Makefile.in (clean): No longer run nextstep's clean.
4883 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4885 (ns-app): Move here from ns.mk, and simplify.
4886 (clean): Simplify nextstep entry.
4887 * ns.mk: Remove file.
4889 2012-09-17 Kenichi Handa <handa@gnu.org>
4891 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4892 not covert the last few charactes.
4894 2012-09-16 Kenichi Handa <handa@gnu.org>
4896 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4897 here, but just check the validity of glyphs in the glyph-string.
4899 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4901 * window.c (Fwindow_parameter, Fset_window_parameter):
4902 Accept any window as argument (Bug#12452).
4904 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4906 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4907 to ns_term_init to avoid memory leak.
4909 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4910 explicit retain/release.
4911 (ns_term_init): Only allow one display. Initialize outerpool and
4914 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4916 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4917 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4918 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4919 the Microsoft problem in a different way, by altering ../nt/config.nt.
4921 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4936 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4937 by lisp.h. This completes removal of setjmp.h inclusion
4938 erroneously announced in the previous commit. (Bug#12446)
4940 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4943 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4944 not defined as a macro. The latter happens on MS-Windows.
4947 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4949 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4950 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4951 Some instances of '#include <setjmp.h>' removed, if the
4952 only reason for the instance was because "lisp.h" was included.
4953 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4954 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4955 and _longjmp with the new symbols. Emacs already uses _setjmp if
4956 available, so this change affects only POSIXish hosts that have
4957 sigsetjmp but not _setjmp, such as some versions of Solaris and
4958 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4959 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4960 (png_load_body) [HAVE_PNG]:
4961 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4962 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4963 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4964 since PNG requires jmp_buf. This is the only exception to the
4965 general rule that we now use sys_setjmp and sys_longjmp.
4966 This exception is OK since this code does not change the signal
4967 mask or longjmp out of a signal handler.
4969 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4971 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4972 Include "syssignal.h", for 'main_thread'.
4974 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4976 Avoid out-of-range marker position (Bug#12426).
4977 * insdel.c (replace_range, replace_range_2):
4978 Adjust markers before overlays, as suggested by comments.
4979 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4980 Remove redundant check before calling offset_intervals.
4982 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4984 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4985 current buffer (Bug#12387).
4987 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4989 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4991 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4993 Use a more backwards-compatible timer format (Bug#12430).
4994 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4995 vector element, not from the 4th, since PSECS is now at the end.
4996 (Fcurrent_idle_time): Doc fix.
4998 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5000 Function to mark objects and remove killed buffers at once.
5001 * alloc.c (discard_killed_buffers): Rename to ...
5002 (mark_discard_killed buffers) ... new name. Add marking
5003 of remaining objects. Fix comment. Adjust users.
5004 (mark_object): Do not touch frame buffer lists here.
5005 * frame.c (delete_frame): Reset frame buffer lists here.
5007 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5009 Better workaround for GNOME bug when --enable-gcc-warnings.
5010 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5011 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5012 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5014 Simplify SIGIO usage (Bug#12408).
5015 The code that dealt with SIGIO was crufty and confusing, e.g., it
5016 played tricks like "#undef SIGIO" but these tricks were not used
5017 consistently. Simplify mostly by not #undeffing standard symbols,
5018 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5019 or not as we please) rather than "defined SIGIO" (standard symbol
5020 that we probably shouldn't #undef).
5021 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5022 Modules that need it can include it.
5023 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5024 * dispextern.h (ignore_sigio): New decl.
5025 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5026 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5027 * emacs.c (shut_down_emacs):
5028 * keyboard.c (kbd_buffer_store_event_hold):
5029 Use ignore_sigio rather than invoking 'signal' directly.
5030 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5032 (FIONREAD, SIGIO): Do not #undef.
5033 (tty_read_avail_input): Use #error rather than a syntax error.
5034 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5035 for I_PIPE, used by SETUP_SLAVE_PTY.
5036 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5037 * sysdep.c (croak): Remove; no longer needed. This bit of
5038 temporary code, with Fred N. Fish's comment that it's temporary,
5039 has been in Emacs since at least 1992!
5040 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5041 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5042 * syssignal.h (croak): Remove decl.
5043 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5044 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5045 now that we're termios-only.
5046 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5047 * term.c (dissociate_if_controlling_tty): Use #error rather than
5050 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5051 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5052 to work around GNOME bug 683906.
5053 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5054 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5055 This works around GCC bug 54561.
5057 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5059 More fixes for 'volatile' and setjmp/longjmp.
5060 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5061 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5062 (png_load_body) [HAVE_PNG]:
5063 (jpeg_load_body) [HAVE_JPEG]:
5064 New function, with most of the old parent function's body.
5065 (png_load) [HAVE_PNG]:
5066 (jpeg_load) [HAVE_JPEG]:
5067 Invoke the new function, to avoid longjmp munging our locals.
5068 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5069 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5070 longjmp is passed 2, as the C standard doesn't guarantee this.
5071 Instead, store the failure code into mgr->failure_code.
5073 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5075 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5076 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5077 (syms_of_keyboard): Remove support for unread-command-char.
5079 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5081 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5082 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5083 violation. (Bug#12426)
5085 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5087 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5089 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5091 * eval.c: Add `inhibit-debugger'.
5092 (Qinhibit_debugger): New symbol.
5093 (call_debugger): Bind it instead of Qdebug_on_error.
5094 (maybe_call_debugger): Test Vinhibit_debugger.
5095 (syms_of_eval): Define inhibit-debugger.
5096 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5097 (syms_of_xdisp): Remove inhibit-debug-on-message.
5099 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5101 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5102 If a nonvolatile local variable is written before a _longjmp to
5103 the frame containing the variable, and is read after the _longjmp,
5104 the value read is indeterminate. Some local variables of type
5105 'struct handler' and 'struct catchtag' are used in this way, so
5106 mark each of their slots as volatile if the slot can be set before
5107 _longjmp and read afterwards.
5108 * lisp.h (struct handler): var and chosen_clause are now volatile.
5109 (struct catchtag): val, next, and pdlcount are now volatile.
5111 * bidi.c (bidi_push_it, bidi_pop_it):
5112 * fns.c (copy_hash_table):
5113 * image.c (define_image_type):
5114 * keyboard.c (kbd_buffer_store_event_hold):
5115 * process.c (Fprocess_send_eof):
5116 * xfaces.c (x_create_gc) [HAVE_NS]:
5117 * xgselect.c (xg_select):
5118 Prefer assignment to memcpy when either will do.
5120 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5121 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5122 time an item is removed. No need to mark this function 'inline';
5123 the compiler knows better than we do.
5125 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5127 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5128 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5129 to change_frame_size (Bug#12388).
5130 (windowDidResize:): Pass YES to updateFrameSize.
5132 * nsterm.h: Add delay parameter to updateFrameSize.
5134 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5136 Discard killed buffers from deleted window and frame objects.
5137 This reduces an amount of references to killed buffers and
5138 helps GC to reclaim them faster.
5139 * alloc.c (discard_killed_buffers): New function.
5140 (mark_object): Use it for deleted windows and frames.
5141 (mark_object): If symbol's value is set up for a killed buffer
5142 or deleted frame, restore its global binding.
5143 * data.c (swap_in_global_binding): Add GC notice.
5144 (swap_in_symval_forwarding): Use convenient set_blv_where.
5145 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5146 * window.h: ... to here.
5148 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5150 Convenient macro to check whether the buffer is live.
5151 * buffer.h (BUFFER_LIVE_P): New macro.
5152 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5153 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5155 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5157 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5158 composition cases (Bug#12364).
5160 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5161 overhang of succeeding glyphs overlapping box cursor.
5163 * w32term.c (x_draw_glyph_string): Likewise.
5165 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5167 Simplify, document, and port floating-point (Bug#12381).
5168 The porting part of this patch fixes bugs on non-IEEE platforms
5169 with frexp, ldexp, logb.
5170 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5172 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5173 support, by removing commented-out code and briefly listing the
5174 C89 functions excluded. The commented-out stuff was confusing
5175 maintenance, e.g., we thought we needed cbrt but it was commented out.
5176 (logb): Remove decl; no longer needed.
5177 (isfinite): New macro, if not already supplied.
5178 (isnan): Don't replace any existing macro.
5179 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5180 are present on all C89 platforms.
5181 (Ffrexp): Do not special-case zero, as frexp does the right thing
5183 (Flogb): Do not use logb, as it doesn't have the desired meaning
5184 on hosts that use non-base-2 floating point. Instead, stick with
5185 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5186 frexp, to avoid getting an unspecified result.
5188 * xdisp.c (Qinhibit_debug_on_message): Now static.
5190 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5192 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5193 NSBezierPath (Bug#12131).
5195 2012-09-10 Chong Yidong <cyd@gnu.org>
5197 * fns.c (Fdelq, Fdelete): Doc fix.
5199 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5201 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5202 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5204 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5206 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5207 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5210 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5212 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5213 left fringe if the window has a left margin. This avoids leaving
5214 traces of the cursor because its leftmost pixel is not drawn over.
5216 * dispnew.c (update_window_line): When the left margin area of a
5217 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5218 that screen line. (Bug#12277)
5220 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5222 Assume C89 or later for math functions (Bug#12381).
5223 This simplifies the code, and makes it a bit smaller and faster,
5224 and (most important) makes it easier to clean up signal handling
5225 since we can stop worring about floating-point exceptions in
5226 library code. That was a problem before C89, but the problem
5227 went away many years ago on all practical Emacs targets.
5228 * data.c, image.c, lread.c, print.c:
5229 Don't include <math.h>; no longer needed.
5230 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5231 might be autoconfigured, as that never happens.
5233 * doprnt.c (DBL_MAX_10_EXP):
5234 * print.c (DBL_DIG):
5235 Remove. C89 or later always defines these.
5236 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5237 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5238 (arith_error, domain_error, domain_error2):
5239 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5240 no longer needed -- we simply return what C returns. All uses removed.
5241 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5243 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5244 Remove. All uses expanded, as these macros are no longer used
5245 more than once and are now more trouble than they're worth.
5246 (Ftan): Use tan, not sin / cos.
5247 (Flogb): Assume C89 frexp.
5248 (fmod_float): Assume C89 fmod.
5249 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5250 (init_floatfns): Remove. All uses removed.
5252 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5254 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5255 compositeToPoint for OSX < 10.6 (Bug#12390).
5257 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5259 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5260 This produces more-accurate results.
5262 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5264 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5265 changes (Bug#12088).
5267 2012-09-08 Chong Yidong <cyd@gnu.org>
5269 * syntax.c (Fstring_to_syntax): Doc fix.
5271 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5273 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5274 in the internal border.
5275 (x_set_window_size): Remove static variables and their usage.
5276 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5277 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5278 Remove fringe/internal border adjustment (Bug#11052).
5279 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5280 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5281 (ns_fix_rect_ibw): Remove.
5282 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5283 (ns_dumpglyphs_box_or_relief): Ditto.
5284 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5286 (ns_dumpglyphs_image): Ditto.
5287 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5289 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5290 their usage. Add fringe_extended_p and its use as in other terms.
5291 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5292 scroll bar was removed.
5293 (updateFrameSize): New function.
5294 (windowDidResize): Move code to updateFrameSize and call it.
5296 * nsterm.h (EmacsView): Add updateFrameSize.
5298 2012-09-07 Chong Yidong <cyd@gnu.org>
5300 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5302 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5304 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5306 More signal-handler cleanup (Bug#12327).
5307 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5308 Problem introduced when merging patches. Noted by Eli Zaretskii in
5309 <http://bugs.gnu.org/12327#67>.
5310 * floatfns.c: Comment fix.
5311 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5312 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5313 and anyway the declaration is harmless even if SIGDANGER is not defined.
5314 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5315 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5316 source files not surprisingly expected syssignal.h to define, or
5317 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5318 Include <sys/ioctl.h>, for FIONREAD.
5319 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5320 This eliminates a problem whereby other files mysteriously had
5321 to include "syssignal.h" before including "systty.h" if they
5322 wanted to use "#ifdef SIGIO".
5324 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5326 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5328 * w32.c (sigemptyset): Empty the set.
5329 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5331 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5333 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5335 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5336 (mark_object): Likewise for frame objects.
5338 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5340 * syssignal.h (handle_on_main_thread): Always declare,
5341 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5342 This ports to platforms without HAVE_PTHREAD.
5344 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5346 Signal-handler cleanup (Bug#12327).
5347 Emacs's signal handlers were written in the old 4.2BSD style with
5348 sigblock and sigmask and so forth, and this led to some
5349 inefficiencies and confusion. Rewrite these to use
5350 pthread_sigmask etc. without copying signal sets around. Also,
5351 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5352 'signal', and instead use functions that do not attempt to take
5353 over the system name space. This patch causes Emacs's text
5354 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5355 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5356 Do not include <signal.h> or "syssignal.h", as these
5357 modules do not use signals.
5358 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5359 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5360 Do not include <signal.h>, as "syssignal.h" does that for us now.
5361 * atimer.c (sigmask_atimers): New function.
5362 (block_atimers, unblock_atimers): New functions,
5363 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5365 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5366 no longer needed here.
5367 * emacs.c (main): Inspect existing signal handler with sigaction,
5368 so that there's no need to block and unblock SIGHUP.
5369 * sysdep.c (struct save_signal): New member 'action', replacing
5370 old member 'handler'.
5371 (save_signal_handlers, restore_signal_handlers):
5372 Use sigaction instead of 'signal' to save and restore.
5373 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5374 New function. All users of 'signal' modified to use set_sighandler
5375 if they're writeonly, and to use sys_signal if they're read+write.
5376 (emacs_sigaction_init, forwarded_signal): New functions.
5377 (sys_signal): Remove. All uses replaced by calls to sigaction
5378 and emacs_sigaction_init, or by direct calls to 'signal'.
5379 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5380 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5381 all uses replaced by pthread_sigmask etc. calls.
5382 * syssignal.h: Include <signal.h>.
5383 (emacs_sigaction_init, forwarded_signal): New decls.
5384 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5385 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5386 (sigmask, sys_sigmask): Remove; no longer needed.
5387 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5388 (sigblock, sigunblock, sigfree):
5389 (sigsetmask) [!defined sigsetmask]:
5390 Remove. All uses replaced by pthread_sigmask.
5391 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5392 no longer need to be replaced, and its typical old uses
5393 are now done via emacs_sigaction_init and sigaction.
5394 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5395 (sys_sigdel): Remove; unused.
5396 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5398 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5400 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5401 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5403 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5405 Explicitly mark buffer_defaults and buffer_local_symbols.
5406 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5407 mark_local_symbols here.
5408 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5409 since special buffers aren't marked here any more.
5410 (allocate_buffer): Chain new buffer with all_buffers here...
5411 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5413 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5414 (syms_of_buffer): Remove staticpro of the above.
5415 (init_buffer_once): Set names for buffer_defaults and
5416 buffer_local_symbols.
5418 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5420 Use bool for booleans in font-related modules.
5421 * font.c (font_intern_prop, font_style_to_value)
5422 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5423 (generate_otf_features, font_check_otf_features, font_check_otf)
5424 (font_match_p, font_list_entities, font_at):
5425 * fontset.c (fontset_id_valid_p, reorder_font_vector
5426 (fontset_find_font, Fset_fontset_font)
5427 (face_suitable_for_char_p) [0]:
5428 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5429 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5430 (m17n_flt_initialized, ftfont_shape_by_flt):
5431 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5432 * nsfont.m (nsfont_draw):
5433 * w32font.c (w32font_draw):
5434 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5435 Use bool for booleans.
5436 * font.h: Adjust to above API changes.
5437 (struct font, struct font_driver, struct font_driver_list):
5438 Use bool for booleans.
5439 (struct font): Remove useless member encoding_type.
5441 * fontset.c, xftfont.c: Omit unnecessary static decls.
5443 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5445 * alloc.c (mark_object): Revert window marking code
5446 since it's unsafe for the Fset_window_configuration.
5448 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5450 Fix race conditions with signal handlers and errno (Bug#12327).
5451 Be more systematic about preserving errno whenever a signal
5452 handler returns, even if it's not in the main thread. Do this by
5453 renaming signal handlers to distinguish between signal delivery
5454 and signal handling. All uses changed.
5455 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5456 * data.c (deliver_arith_signal): Rename from arith_error.
5457 * dispnew.c (deliver_window_change_signal): Rename from
5458 window_change_signal.
5459 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5460 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5461 * keyboard.c (deliver_input_available_signal): Rename from
5462 input_available_signal.
5463 (deliver_user_signal): Rename from handle_user_signal.
5464 (deliver_interrupt_signal): Rename from interrupt_signal.
5465 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5466 (deliver_child_signal): Rename from sigchld_handler.
5467 * atimer.c (handle_alarm_signal):
5468 * data.c (handle_arith_signal):
5469 * dispnew.c (handle_window_change_signal):
5470 * emacs.c (handle_fatal_signal, handle_danger_signal):
5471 * keyboard.c (handle_input_available_signal):
5472 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5473 * process.c (handle_pipe_signal, handle_child_signal):
5474 New functions, with the actual signal-handling code taken from the
5475 original respective signal handlers, sans the sporadic attempts to
5476 preserve errno, since that's now done by handle_on_main_thread.
5477 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5478 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5479 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5481 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5482 Move initialization of main_thread to sysdep.c's init_signals.
5483 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5484 our usage, and simplifies the mainline code.
5485 (record_child_status_change): New static function, as a helper
5486 for handle_child_signal, and with most of the old child handler's
5488 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5489 (handle_child_signal): Use the above.
5490 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5491 Moved here from emacs.c.
5492 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5493 code moved here from emacs.c's main function.
5494 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5495 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5496 This lets callers save and restore errno properly.
5498 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5500 Remove redundant or unused things here and there.
5501 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5502 * conf_post.h (RE_TRANSLATE): Use char_table_translate.

5504 * frame.h (struct terminal, struct font_driver_list):
5505 Remove redundant declarations.
5506 * window.h (Qleft, Qright): Likewise.
5508 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5510 Do not mark objects from deleted buffers, windows and frames.
5511 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5512 (mark_object): Likewise for windows and frames.
5514 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5516 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5517 buffer_defaults and buffer_local_symbols as valid objects.
5518 Return special value to denote them.
5520 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5522 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5523 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5524 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5525 (file_name_absolute_p, Fsubstitute_in_file_name):
5526 (check_executable, check_writable, Ffile_accessible_directory_p)
5527 (Fset_file_selinux_context, Fdefault_file_modes)
5528 (Finsert_file_contents, choose_write_coding_system)
5529 (Fwrite_region, build_annotations, a_write, e_write)
5531 * filelock.c (boot_time_initialized, get_boot_time)
5532 (get_boot_time_1, lock_file_1, within_one_second):
5533 * floatfns.c (in_float):
5534 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5535 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5536 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5537 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5538 * window.c (compare_window_configurations):
5539 Use bool for booleans.
5540 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5541 (Fdefault_file_modes): Now mode_t, not int, for modes.
5542 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5543 (internal_delete_file): Now returns void, not a (boolean) int,
5544 since nobody was looking at the return value.
5545 * lisp.h, window.h: Adjust to above API changes.
5547 * xdisp.c (set_message): Simplify and reindent last change.
5549 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5551 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5553 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5555 * eval.c (call_debugger): Make the function non-static so that we
5556 can call it from set_message.
5558 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5559 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5561 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5563 Give more-useful info on a fatal error (Bug#12328).
5564 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5565 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5566 of doing the work ourselves.
5567 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5568 do most of the work.
5569 (fatal_error_backtrace): New function, taken from the guts
5570 of the old fatal_error_signal, but with a new option to output
5572 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5573 info about the signal than just its number.
5574 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5575 * sysdep.c: Include <execinfo.h>
5576 (emacs_backtrace): New function, taken partly from the previous
5577 code of the 'die' function.
5578 (emacs_abort): Call fatal_error_backtrace rather than abort.
5580 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5582 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5583 eager (load-time) macro-expansion.
5584 * lisp.mk (lisp): Add macroexp.
5586 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5588 Simplify redefinition of 'abort' (Bug#12316).
5589 Do not try to redefine the 'abort' function. Instead, redo
5590 the code so that it calls 'emacs_abort' rather than 'abort'.
5591 This removes the need for the NO_ABORT configure-time macro
5592 and makes it easier to change the abort code to do a backtrace.
5593 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5594 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5595 Remove; sysdep.c's emacs_abort now takes its place.
5596 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5597 'abort' changed to use 'emacs_abort'.
5598 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5599 (abort) [!defined abort]: Rename to ...
5600 (emacs_abort): ... new name.
5601 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5602 the place of the old 'abort' in emacs.c.
5603 * w32.c, w32fns.c (abort): Do not #undef.
5604 * w32.c (emacs_abort): Rename from w32_abort.
5606 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5608 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5609 offsets[j].dv, since the y axis of the screen coordinates points
5610 down, while the y axis of the font definition coordinates points
5611 up. This fixes display of Arabic diacritics such as KASRA and
5612 KASRATAN. (Bug#11860)
5614 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5616 Be more systematic about _setjmp vs setjmp.
5617 * alloc.c (test_setjmp, mark_stack):
5618 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5619 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5620 (png_load, my_error_exit, jpeg_load):
5621 * process.c (send_process_trap, send_process):
5622 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5623 The underscored versions are up to 30x faster on some hosts.
5624 Formerly, the code used setjmp+longjmp sometimes and
5625 _setjmp+_longjmp at other times, with no particular reason to
5626 prefer setjmp+longjmp.
5628 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5630 Fix minor problem found by static checking.
5631 * buffer.c (Fdelete_all_overlays): Return nil.
5633 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5635 * buffer.c (Fdelete_all_overlays): New function.
5637 2012-09-03 Chong Yidong <cyd@gnu.org>
5639 * gtkutil.c: Add extern decl for Qxft.
5641 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5655 All callers changed.
5656 * eval.c (interactive_p): Omit always-true boolean argument
5657 EXCLUDE_SUBRS_P. All callers changed.
5658 * dispextern.h, lisp.h: Reflect above API changes.
5659 * firstfile.c (dummy): Use the address of 'main', whose signature
5660 won't change, instead of the address of 'initialize', whose
5661 signature just changed from int to bool.
5662 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5663 * msdos.c (fatal_error_in_progress): ... from here.
5664 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5666 (redisplay_internal, unwind_redisplay): Simply clear
5667 REDISPLAYING_P when unwinding, instead of saving its previous,
5668 always-false value and then restoring it.
5670 Clean up some extern decls.
5671 Mostly, this hoists extern decls out of .c files and into .h files.
5672 That way, we're more likely to catch errors if the interfaces change.
5673 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5674 declare xg_mark_data.
5675 * dispextern.h (x_frame_parm_handlers):
5677 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5678 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

5693 * xfont.c (x_clear_errors):
5694 * xterm.c (x_frame_parm_handlers):
5695 Remove now-redundant extern decls.
5696 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5697 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5699 * xfaces.c: Remove unnecessary static decls.
5700 * xterm.c (updating_frame): Remove decl of nonexistent object.
5702 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5703 when building globals.h, as the objects that are not built on
5704 this host are not needed to compile C files on this host.
5706 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5708 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5722 (make_buffer_string, make_buffer_string_both)
5723 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
5724 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

5734 (get_property_and_range, compare_string_intervals)
5735 (set_intervals_multibyte_1, set_intervals_multibyte):
5736 * keyboard.c (decode_timer):
5737 Use bool for boolean.
5738 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5739 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5741 2012-09-02 Chong Yidong <cyd@gnu.org>
5743 * keymap.c (push_key_description): Print M-TAB as C-M-i
5746 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5748 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5749 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

5754 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5756 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5758 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5759 more than one grapheme cluster passed to the shaper: compute the
5760 offset adjustment values separately for each cluster. (Bug#11860)
5762 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5763 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5764 about implicit conversions from integer to pointer.
5766 2012-09-01 Daniel Colascione <dancol@dancol.org>
5768 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5769 system used too early.
5771 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5773 Better seed support for (random).

5802 * process.c: Include TERM_HEADER instead of listing all possible
5803 window-system headers.
5805 * nsterm.h: Remove declarations now in frame.h.
5806 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
5808 * menu.c: Include TERM_HEADER instead of listing all possible
5809 window-system headers.
5811 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
5814 * keyboard.c: Include TERM_HEADER instead of listing all possible
5815 window-system headers.
5817 * image.c: Include TERM_HEADER instead of listing all possible
5818 window-system headers. Declare Vlibrary_cache when compiling for
5821 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
5822 window system declarations.
5824 * frame.h: Move common functions here: set_frame_menubar,
5825 x_set_window_size, x_sync, x_get_focus_frame,
5826 x_set_mouse_position, x_set_mouse_pixel_position,
5827 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5848 the current window system; include in list of objects to link into
5851 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5853 Remove mark_ttys function and fix tty_display_info initialization.
5854 * lisp.h (mark_ttys): Remove prototype.
5855 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5856 to mark_ttys because all possible values of 'top_frame' slot are
5857 the frames which are reachable from Vframe_list.
5858 * term.c (mark_ttys): Remove.
5859 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5861 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5863 Change struct frame bitfields from unsigned char to unsigned.
5864 * frame.h (struct frame): Change type of 'display_preempted',

5866 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
5867 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
5868 bitfields from unsigned char to unsigned.
5870 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5872 Remove unused member of struct x_output and struct w32_output.

5876 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
5878 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5879 does not become zero (Bug#12234).
5881 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
5883 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5884 for GCC 4.7.1 x86-64.
5886 2012-08-30 Glenn Morris <rgm@gnu.org>
5888 * lread.c (init_lread): For out-of-tree builds, only add the
5889 source directory's site-lisp dir to the load-path if it exists,
5890 consistent with in-tree builds. (Bug#12302)
5892 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5894 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5896 (windowShouldClose:): Set window_closed.
5897 (dealloc): New member, free button_values.
5898 (process_dialog:): Make member function. Remove window argument,
5899 replace window with self. Count buttons and allocate and store values
5901 (addButton:value:row:): value is int with the name tag. Call setTag
5902 with tag. Remove return self, declare return value as void.
5903 (addString:row:): Remove return self, declare return value as void.
5904 (addSplit): Remove return self, declare return value as void.
5905 (clicked:): Remove return self, declare return value as void.
5906 Set dialog_return to button_values[seltag]. Code formatting change.
5907 (initFromContents:isQuestion:): Adjust call to process_dialog.
5908 Code formatting change.
5909 (timeout_handler:): Set timer_fired to YES.
5910 (runDialogAt:): Set timer_fired to NO.
5911 Handle click on close button as quit.
5913 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5914 Add window_closed and button_values. Add void as return value for
5915 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5916 Add process_dialog as new member.
5918 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5920 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
5921 is not one of the heaps we manage. (Bug#12242)
5923 2012-08-28 Glenn Morris <rgm@gnu.org>
5925 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
5927 2012-08-28 Martin Rudalics <rudalics@gmx.at>

5981 (change_frame_size_1, sit_for):
5982 Use bool for boolean.
5983 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
5984 and remove last int (actually boolean) argument, which was always 0.
5985 All callers changed.
5986 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
5987 * dispextern.h (struct composition_it): Use bool for boolean.
5988 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
5989 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
5990 * dired.c (file_name_completion):
5991 Use bool for boolean. (This was missed in an earlier change.)
5993 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5995 * window.c (Fset_window_configuration): Revert first part of
5998 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
6000 * nsterm.h (NSPanel): New class variable dialog_return.
6002 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
6003 Initialize dialog_return.
6004 (windowShouldClose:): Use stop instead of stopModalWithCode.
6005 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6006 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6008 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
6011 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
6013 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.

6023 Use bool for booleans.
6024 * dired.c (file_name_completion):

6053 Use bool for booleans.
6054 * coding.h, lisp.h: Reflect above API changes.
6055 * coding.c: Remove unnecessary static function decls.
6056 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6057 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6058 not a boolean 'int', since callers never look at the return value.
6059 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6060 * coding.h (decoding_buffer_size, encoding_buffer_size)
6061 (emacs_mule_string_char): Remove unused extern decls.
6062 (struct iso_2022_spec, struct coding_system):
6063 Use 'unsigned int : 1' for boolean fields, since there's more than one.
6064 (struct emacs_mule_spec): Remove unused field 'full_support'.
6065 All initializations removed.
6066 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6068 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6070 Fix spare memory change (Bug#12286).
6071 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6072 (valid_lisp_object_p): Likewise.
6074 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6076 * window.c (Fset_window_configuration): Record any window's old
6077 buffer if it's replaced (see Bug#8789). If the new current
6078 buffer doesn't appear in the selected window, go to its old
6081 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6083 Special MEM_TYPE_SPARE to denote reserved memory.
6084 * alloc.c (enum mem_type): New memory type.
6085 (refill_memory_reserve): Use new type for spare memory.
6086 This prevents live_cons_p and live_string_p from incorrect
6087 detection of uninitialized objects from spare memory as live.
6089 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6092 * Makefile.in (.PHONY): versioclean -> versionclean.
6094 Remove unused external symbols.
6095 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6096 * window.c (Qwindow_valid_p, decode_valid_window):
6097 Now static, not extern.
6098 * data.c (Qinterval): Remove; unused.
6099 (syms_of_data): Do not define 'interval'.
6100 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6101 * window.h (decode_valid_window):
6104 * character.c, charset.c, chartab.c: Use bool for booleans.
6105 * character.c (lisp_string_width, string_count_byte8)
6106 (string_escape_byte8):

6113 (sub_char_table_set, sub_char_table_set_range)
6114 (char_table_set_range, optimize_sub_char_table)
6115 (map_sub_char_table):
6116 Use bool for boolean.
6117 * character.c (str_to_unibyte): Omit last boolean argument; it was
6118 always 0. All callers changed.
6119 * character.h, charset.h: Adjust to match previous changes.
6120 * character.h (char_printable_p): Remove decl of nonexistent function.
6121 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6122 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6123 are all boolean, so make them single-bit bitfields.
6125 * lisp.h (ASET): Remove attempt to detect side effects.
6126 It was meant to be temporary and it often doesn't work,
6127 because when IDX has side effects the behavior of IDX==IDX
6128 is undefined. See Stefan Monnier in
6129 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6131 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6133 * lisp.h (functionp): New function (extracted from Ffunctionp).
6134 (FUNCTIONP): Use it.
6135 * eval.c (Ffunctionp): Use it.
6137 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6139 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6140 as that's faster and simpler than static storage. Don't bother
6141 with the g_main_context_query overhead if g_main_context_pending
6142 says no events are pending.
6143 (gfds, gfds_size): Remove these static vars.
6144 (xgselect_initialize): Remove; no longer needed.
6145 All uses and decls removed.
6147 * emacs.c (fatal_error_signal_hook): Remove.
6148 All uses removed. This leftover from old code was always 0.
6150 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6151 * casefiddle.c (casify_object, casify_region):
6152 * casetab.c (set_case_table):
6153 * category.c, category.h (word_boundary_p):
6154 * category.h (CHAR_HAS_CATEGORY):
6155 Use bool for booleans, instead of int.
6157 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6159 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6161 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6163 On assertion failure, print backtrace if available.
6164 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6165 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6166 * Makefile.in (LIB_EXECINFO): New macro.
6169 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6170 * bytecode.c (exec_byte_code):
6171 * callint.c (check_mark, Fcall_interactively):
6172 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6173 (getenv_internal, sync_process_alive, call_process_exited):
6174 * lisp.h (USE_SAFE_ALLOCA):
6175 Use bool for booleans, instead of int.
6176 * lisp.h, process.h: Adjust prototypes to match above changes.
6177 * callint.c (Fcall_interactively): Don't assume the mark's
6178 offset fits in 'int'.
6180 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6182 * buffer.c, buffer.h: Use bool for boolean.
6183 * buffer.c (reset_buffer_local_variables)
6184 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6185 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

6187 (overlay_touches_p, overlay_strings, Foverlay_put)
6188 (report_overlay_modification, call_overlay_mod_hooks):
6189 (mmap_enlarge, mmap_set_vars):
6190 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6191 Use bool for booleans, instead of int.
6192 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6193 since the 1-or-0 return value is always ignored anyway.
6194 (mmap_initialized_p):
6195 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6196 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6198 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6200 * bidi.c: Use bool for boolean.
6201 This is a bit more readable, and makes the text segment of bidi.o
6202 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6203 Presumably it's faster too.
6204 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6206 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6207 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6208 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6209 (bidi_explicit_dir_char, bidi_level_of_next_char)
6210 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6211 Use bool for booleans, instead of int.
6212 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6213 (bidi_unshelve_cache): Adjust decls to match code.
6215 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6217 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6220 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6222 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6223 * atimer.h: Include <stdbool.h>.
6225 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6227 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6228 compile time tests instead of run time tests on systems that do
6230 (FRAME_MAC_P): Remove leftover from deleted code.
6231 * frame.c (syms_of_frame): Remove leftover from deleted code.
6233 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6235 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6237 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6239 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6240 Otherwise, the compiler complains about (A?B:C) where B is void
6241 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6242 (fontset_add): Return void, for FONTSET_ADD.
6244 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6246 * alloc.c: Use bool for booleans.
6247 (gc_in_progress, abort_on_gc)
6248 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6249 (dont_register_blocks) [GC_MALLOC_CHECK]:
6250 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6251 (check_string_bytes, make_specified_string, memory_full)
6252 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6253 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6254 (mark_stack, valid_pointer_p, make_pure_string)
6255 (Fgarbage_collect, survives_gc_p, gc_sweep):
6256 Use bool for booleans, instead of int.
6257 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6258 Remove unused local.
6259 * alloc.c (PURE_POINTER_P):
6260 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6261 * editfns.c (Fformat):
6262 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6264 * fns.c (sweep_weak_table):
6265 * lisp.h (suppress_checking, push_message, survives_gc_p)
6266 (make_pure_string, gc_in_progress, abort_on_gc):
6267 * lread.c (readchar, read1):
6268 * print.c (Fprin1_to_string):
6269 * xdisp.c (push_message):
6270 Use bool for booleans affected directly or indirectly by
6273 Make recently-introduced setters macros.
6274 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6275 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6276 (set_fontset_default, set_fontset_fallback): Rename from their
6277 upper-case counterparts, and make them functions rather than macros.
6278 This is more consistent with the other recently-introduced setters.
6279 These don't need to be inline, since they're local.
6281 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6283 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6284 the loop (Bug#12247).
6286 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6288 * lisp.h (vcopy): Use memcpy rather than our own loop.
6289 This fixes a performance regression introduced by the recent
6290 addition of vcopy. This means 'vcopy' will need to be modified
6291 for a copying collector, but that's OK. Also, tighten the
6292 checking in the assertion.
6294 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6296 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6297 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6298 non-base glyph for the width of the base character, according to
6299 what x_draw_composite_glyph_string_foreground expects.
6300 Generate WADJUST value according to composition_gstring_width's
6301 expectations, to produce correct width of the composed character.
6302 Reverse the sign of the DU offset produced by ScriptPlace.
6304 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6306 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6308 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6310 Avoid direct writes to contents member of struct Lisp_Vector.
6311 * lisp.h (vcopy): New function to copy data into vector.
6312 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6313 * fns.c (Ffillarray): Use ASET.
6314 * keyboard.c (timer_check_2): Use AREF and ASET.
6315 (append_tool_bar_item, Frecent_keys): Use vcopy.
6316 * lread.c (read_vector): Use ASET.
6317 * msdos.c (Frecent_doskeys): Use vcopy.
6318 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6319 (Finternal_merge_in_global_face): Use ASET and vcopy.
6320 * xfont.c (xfont_list_pattern): Likewise.
6322 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6324 * window.c (Fwindow_point): For the selected window always return
6325 the position of its buffer's point.
6326 (Fset_window_point): For the selected window always go in its
6327 buffer to the specified position.
6329 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6331 Setter macros for fontsets.
6332 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6333 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6334 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6337 2012-08-20 Glenn Morris <rgm@gnu.org>
6339 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6340 Don't assume that `ln -f' works.
6342 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6344 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6345 and later about non-assignments with no effect. See discussion at
6346 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6349 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6351 Inline setter functions for Lisp_Objects slots of struct specbinding.
6352 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6355 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6357 * window.c (select_window): Always make selected window's buffer
6360 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6362 Use AREF and ASET for docstrings of category tables.
6363 * category.h (CATEGORY_DOCSTRING): Use AREF.
6364 (SET_CATEGORY_DOCSTRING): Use ASET.
6365 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6367 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6369 Inline setter functions for hash table members.
6370 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6371 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6372 (set_hash_key_and_value, set_hash_index, set_hash_next)
6373 (set_hash_hash): New functions.
6374 * charset.c, fns.c: Adjust users.
6376 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6378 Inline getter and setter functions for per-buffer values.
6379 * buffer.h (per_buffer_default, set_per_buffer_default)
6380 (per_buffer_value, set_per_buffer_value): New functions.

6382 * buffer.c, data.c: Adjust users.
6384 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6386 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6388 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6390 Rely on <config.h> + <unistd.h> to declare 'environ',
6391 as gnulib does this if the system doesn't.
6392 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6393 Remove declaration. MS-Windows declares it on stdlib.h which is
6394 included by conf_post.h.
6395 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6396 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6397 * vm-limit.c: Include <unistd.h>, for 'environ'.
6399 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6400 (start_of_data): Remove decl; mem-limits.h provides it.
6402 * xdisp.c (handle_invisible_prop): Make it a bit faster
6403 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6405 2012-08-19 Chong Yidong <cyd@gnu.org>

6427 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6428 Return void, not Lisp_Object. Otherwise, the compiler
6429 complains about (A?B:C) where B is void and C is Lisp_Object
6430 when compiling CHAR_TABLE_SET, due to the recent change to
6431 the API of sub_char_table_set_contents.

7261 2012-08-04 Eli Zaretskii <eliz@gnu.org>
7263 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7264 * w32.c (init_environment): Change the default values of many
7265 environment variables in dflt_envvars[] to NULL, to avoid pushing
7266 them into environment when they were not already defined.
7267 Remove the code that deletes site-lisp subdirectories from the default
7268 value of EMACSLOADPATH, as it is no longer needed.
7269 (check_windows_init_file): Now external, not static.
7270 Use Vload_path as is, without adding anything, as this function is now
7271 called when Vload_path is already set up.
7273 * w32.h (check_windows_init_file): Add prototype.
7275 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
7276 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
7277 compatibility with Posix platforms.
7278 (main): Move the call to check_windows_init_file to here from
7280 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
7281 any, in the DEFALT argument into the root of the Emacs build or
7282 installation tree, as appropriate.
7284 * callproc.c (init_callproc_1): Call decode_env_path instead of
7285 doing its equivalent by hand.
7286 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
7287 the code that sets Vexec_path run on MS-Windows.
7289 * lread.c (init_lread): Add comments to #ifdef's.
7291 * msdos.c (dos_set_window_size, IT_update_begin)
7292 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
7293 instead of direct references.
7295 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
7297 Export DEFAULT_REHASH_* to GDB.
7298 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
7299 Now constants, not macros.
7301 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
7303 Remove unnecessary casts involving pointers.
7304 These casts are no longer needed now that we assume C89 or later,
7305 since they involve casting to or from void *.
7306 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
7307 (make_pure_float, make_pure_vector):
7308 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

7314 * xfaces.c (compare_fonts_by_sort_order):
7315 * xfns.c (x_real_positions, select_visual):
7316 * xselect.c (x_stop_queuing_selection_requests)
7317 (x_get_window_property, x_get_window_property_as_lisp_data):
7318 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7319 Remove unnecessary pointer casts.
7320 * alloc.c (record_xmalloc): New function.
7321 * lisp.h (record_xmalloc): New decl.
7322 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7323 more like a function. This is because the pointer cast is not
7324 needed. All uses changed.
7325 * print.c (print_string, print_error_message): Avoid length recalc.
7327 Improve fix for macroexp crash with debugging (Bug#12118).
7328 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7329 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7330 not supposed to be invoked from the garbage collector.
7331 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7332 (gc_aset): New function, which is like ASET but can be
7333 used in the garbage collector.
7334 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
7335 (set_hash_index): Use it instead of ASET.

7344 <g_b_init_create_symbolic_link>: New static flags.
7345 (globals_of_w32): Initialize them to zero.
7346 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
7347 (map_w32_filename): Improve commentary. Simplify switch.
7348 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
7349 headers (most versions of MinGW w32api don't).
7350 (get_security_info, create_symbolic_link)
7351 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
7353 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
7354 in the argument file name.
7355 (sys_access): Call unc_volume_file_attributes only if
7356 GetFileAttributes fails with network-related error codes.
7357 (sys_rename): Diagnose renaming of a symlink when the user doesn't
7358 have the required privileges.
7359 (get_file_security_desc_by_name): Rename from
7360 get_file_security_desc.
7361 (stat_worker): New function, with most of the guts of 'stat', and
7362 with addition of handling of symlinks and support for 'lstat'.
7363 If possible, get file's attributes and security information by
7364 handle, not by name. Produce S_IFLNK bit for symlinks, when
7365 called from 'lstat'.
7366 (stat, lstat): New functions, call 'stat_worker'.
7367 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7368 symlinks when the underlying filesystem supports them.
7370 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7372 Fix macroexp crash on Windows with debugging (Bug#12118).
7373 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7374 checking subscripts; problem introduced with the recent
7375 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7376 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7377 since it's used in non-static inline functions now.
7379 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7380 Don't assume buffer size fits in 'int'. Remove unused local.
7382 Use C99-style 'extern inline' if available.

7384 * category.h (CATEGORY_INLINE):
7385 * character.h (CHARACTER_INLINE):

7394 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7395 * alloc.c (LISP_INLINE):
7396 * buffer.c (BUFFER_INLINE):
7397 * category.c (CATEGORY_INLINE):
7398 * character.c (CHARACTER_INLINE):
7399 * charset.c (CHARSET_INLINE):
7400 * composite.c (COMPOSITE_INLINE):
7401 * dispnew.c (DISPEXTERN_INLINE):
7402 * sysdep.c (SYSTIME_INLINE):
7403 Define to EXTERN_INLINE, so that the corresponding functions
7404 are compiled into code.
7405 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7406 (INLINE_HEADER_END): New macros.
7407 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7427 hard-coding the path separator.
7429 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7431 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7432 This how ASET and AREF are supposed to work, and makes
7433 it easier to think about future improvements. See
7434 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7435 * charset.h (set_charset_attr): New function.
7436 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
7437 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

7816 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
7817 (w32_kbd_patch_key, key_event): Use the codepage returned by
7818 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

7850 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7851 enumeration constants, as PURE and HEAP are too general, and clash
7852 with other headers and sources, such as gmalloc.c and the
7853 MS-Windows system headers. All users changed.
7855 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7857 Revert last save_excursion_save and save_excursion_restore changes.
7858 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7871 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7872 arms of an 'if', not using conditional expressions; otherwise GDB
7873 complains about the types in the unevaluated arm when the argument
7874 is an integer literal.
7875 (xgetint): Simplify expression.
7876 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7877 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7878 Zaretskii in <http://bugs.gnu.org/12036#13>.
7879 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7880 needed now that we have gdb_make_enums_visible.
7881 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7882 (enum enum_USE_LSB_TAG):
7883 New enum types, packaging up enums that need to be exported to GDB.

7925 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7926 emacs.c, as this is a more-suitable home. Had this been done earlier
7927 the fix for 12036 would have avoided some of the problems noted in
7928 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7929 would have been more obvious.
7930 * emacs.c: Do not include <verify.h>; no longer needed.
7931 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7932 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7933 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

7939 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7940 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7941 not be usable in #if. This simplifies things.
7943 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7945 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7950 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7951 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7952 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7953 Adjust to changes in lisp.h and emacs.c, by using
7954 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7955 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7956 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7957 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7958 instead of gdb_valbits.
7959 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7960 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7961 instead of gdb_array_mark_flag.
7962 (xboolvector): Get size from $->size, not $->header.size.
7963 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7964 (xreload, hook-run, hookpost-run): Remove.
7965 * emacs.c: Include <verify.h>.
7966 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7967 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7969 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7970 (gdb_USE_LSB_TAG): New enum constants.
7971 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7972 Also define these as enum constants, so they're visible to GDB.
7973 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7974 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7975 as constants, so they're visible to GDB.

7978 Now enum constants, not macros, so they're visible to GDB.
7979 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7980 more convenient now. All uses changed.
7981 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7982 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7984 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7991 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7992 add argument, tune behavior, and adjust all callers.
7994 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7996 Use typedef for EMACS_INT, EMACS_UINT.
7997 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7998 than macros. This simplifies debugging in the usual case, since
7999 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8000 and it allows expressions involving EMACS_INT casts.
8001 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8003 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8015 Adjust buffer text indirection counters at the end of Fkill_buffer.
8016 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8017 buffer is definitely dead. This should really fix an issue reported
8018 by Christoph Scholtes again. (Bug#12007).
8019 (init_buffer_once): Initialize indirection counters of
8020 buffer_defaults and buffer_local_symbols (for sanity and safety).
8022 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8024 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8025 and continuation glyphs on tooltip frames, leave them at zero.

8053 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8055 Swap buffer text indirection counters in Fbuffer_swap_text.
8056 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8057 This avoids crash reported by Christoph Scholtes at
8058 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8060 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8062 * nsmenu.m (Popdown_data): New struct.
8063 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8065 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8066 (initWithContentRect): Make imgView and contentView non-static
8067 and autorelease them. Also autorelease img and matrix (Bug#12005).
8068 (dealloc): Remove (Bug#12005).
8070 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8072 Adjust consing_since_gc when objects are explicitly freed.

8085 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8087 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8088 as it's limited by the amount of memory, not by INT_MAX.
8090 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8092 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8093 in special-event-map. See the discussion at

8816 * s/aix4-2.h (unix): Remove; no longer needed.
8818 EMACS_TIME simplification (Bug#11875).
8819 This replaces macros (which typically do not work in GDB)
8820 with functions, typedefs and enums, making the code easier to debug.
8821 The functional style also makes code easier to read and maintain.
8822 * systime.h: Include <sys/time.h> on all hosts, not just if
8823 WINDOWSNT, since 'struct timeval' is needed in general.
8824 (EMACS_TIME): Now a typedef, not a macro.

8836 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8837 not functions. All uses rewritten to use the following, respectively:
8838 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8839 (add_emacs_time, sub_emacs_time): New functions.
8840 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

8861 * nsterm.m: Include <ftoastr.h>.
8863 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8864 Prefer snprintf to strncpy.
8865 * nsterm.m (ns_term_init):
8866 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8867 * nsterm.m (ns_term_init):
8868 Avoid the need for strncpy, by using build_string or
8869 make_unibyte_string directly. Use dtoastr, not snprintf.
8870 * process.c (Fmake_network_process): Diagnose service names that
8871 are too long, rather than silently truncating them or creating
8872 non-null-terminated names.
8873 (Fnetwork_interface_info): Likewise, for interface names.
8874 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8875 Prefer sprintf to strncat.
8876 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8877 Prefer vsnprintf to vsprintf + strncpy.
8879 2012-07-10 Glenn Morris <rgm@gnu.org>

8882 Clarify fallback case.
8884 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

8889 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8890 where argument type is known to be a Lisp_Cons.

8902 Optimize pure C strings initialization.
8903 * lisp.h (make_pure_string): Fix prototype.
8904 (build_pure_c_string): New function, defined as static inline. This

8906 the function is called with compile-time constant argument.
8907 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8908 argument, adjust users accordingly. Use build_pure_c_string where

8945 O_RDONLY already includes it).
8947 Stop ns builds setting the EMACSLOADPATH environment variable.
8948 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8949 Now it does not set EMACSLOADPATH, just returns the load-path string.
8950 * nsterm.h: Update accordingly.
8951 * lread.c [HAVE_NS]: Include nsterm.h.
8952 (init_lread) [HAVE_NS]: Use ns_load_path.

8955 2012-07-09 Glenn Morris <rgm@gnu.org>
8957 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8958 since the included bsd-common.h does so.

8961 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8962 (ns_init_paths): Do not set EMACSPATH.

9022 Move marker debugging code under MARKER_DEBUG.
9023 * marker.c (MARKER_DEBUG): Move marker debugging code under
9024 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9025 for bootstrap with --enable-checking (~3x slowdown reported
9026 by Juanma Barranquero <lekktu@gmail.com>).
9027 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9029 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9031 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9032 See <http://bugs.gnu.org/11825#29>.
9034 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9036 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9037 has no font, use the frame's font. (Bug#11813)
9038 (display_line): Add commentary about displaying truncation glyphs
9040 (produce_special_glyphs): Move here from term.c.
9042 * term.c (produce_special_glyphs): Move to xdisp.c.
9044 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9047 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9049 * xdisp.c (display_line): Avoid warning about implicit declaration
9052 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9054 * lisp.h: Remove empty conditional.
9056 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9058 * lread.c (load_path_check): Now static.
9060 Fix some minor --with-ns problems found by static checking.
9061 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9062 (x_set_font) [!HAVE_X_WINDOWS]:
9063 * image.c (xpm_load_image) [HAVE_NS]:
9064 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9065 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9066 Remove unused local.
9067 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9068 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9069 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9070 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9071 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9072 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9073 Fix pointer signedness problem.
9074 * xfaces.c (FRAME_X_FONT_TABLE):
9075 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9077 2012-07-07 Glenn Morris <rgm@gnu.org>
9079 * lread.c (load_path_check): New function, split from init_lread.
9080 (init_lread): Reorganize. Motivation:
9081 If EMACSLOADPATH is set, check/warn about that rather than the
9082 defaults, which we are not going to use. Hence we can remove
9083 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9084 Don't warn if site-lisp directories are missing.
9085 If not installed, start from a blank load-path, since
9086 PATH_LOADSEARCH refers to the eventual installation directories.
9088 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9090 Support truncation and continuation glyphs on GUI frames, when
9091 fringes are disabled. (Bug#11832)
9092 * xdisp.c (init_iterator): Get dimensions of truncation and
9093 continuation glyphs even if on GUI frames.
9094 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9095 or both, are absent.
9096 (start_display, move_it_in_display_line_to): Handle the case of a
9097 GUI frame without a fringe to display continuation or truncation
9099 (insert_left_trunc_glyphs): Support GUI frames: make sure
9100 truncation glyphs overwrite enough glyphs from the current line to
9101 have sufficient space in pixels.
9102 (display_line): Support truncation and continuation glyphs on GUI
9103 frames. If some spare pixels are left on the line after inserting
9104 the truncation glyphs, fill that space with a stretch glyph of a
9105 suitably computed width.
9107 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9108 produce_glyphs, to support GUI sessions.
9110 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9112 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9114 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9116 Do not require float-time's arg to fit in time_t (Bug#11825).
9117 This works better on hosts where time_t is unsigned, and where
9118 float-time is applied to the (negative) difference between two times.
9119 * editfns.c (decode_time_components): Last arg is now double *,
9120 not int *, and means to store all the result as a double, without
9121 worrying about whether the seconds part fits in time_t.
9122 All callers changed.
9123 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9124 All callers changed.
9125 (Ffloat_time): Do not fail merely because the specified time falls
9126 outside of time_t range.
9128 2012-07-07 Glenn Morris <rgm@gnu.org>
9130 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9131 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

9134 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9136 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9137 Update dependencies.
9139 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9141 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9143 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9144 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9145 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9146 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9147 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9148 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9150 * xfont.c (compare_font_names): Redo to omit the need for casts.
9152 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9154 * xfns.c (Fx_change_window_property): Doc fix.
9155 * w32fns.c (Fx_change_window_property): Doc fix.
9157 * w32fns.c (Fx_window_property): Accept the same arguments as the
9158 X Windows version. Doc fix.
9159 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9161 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9162 Eli Zaretskii <eliz@gnu.org>
9164 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9165 Windows-specific code from nt/config.nt moved here.
9166 Obsolete settings removed.
9168 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9170 * process.c: Avoid unnecessary calls to gettime.
9171 (wait_reading_process_output): Don't get the time of day
9172 when gobbling data immediately and not waiting, as there's no need
9173 for it in that case. This removes a FIXME.
9175 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9177 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9178 is defined (Bug#11768).
9180 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9182 Fix marker debugging code.
9183 * marker.c (byte_char_debug_check): Do not perform the check
9184 if buffer is not multibyte.
9185 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9186 Call byte_char_debug_check with correct arguments.
9188 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9190 Compile marker debugging code only if ENABLE_CHECKING is defined.
9191 * marker.c (byte_char_debug_check, count_markers):
9192 Use only if ENABLE_CHECKING is defined.
9193 (byte_debug_flag): Remove.
9194 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9195 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9197 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9199 Avoid code repetition in marker-related functions.
9200 * marker.c (attach_marker): New function.
9201 (Fset_marker, set_marker_restricted, set_marker_both)
9202 (set_marker_restricted_both): Use it.
9203 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9204 Consistently rename charno to charpos.
9205 (marker_position): Add eassert.
9206 (marker_byte_position): Convert to eassert.
9208 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9210 Simplify list operations in unchain_overlay and unchain_marker.

9212 * marker.c (unchain_marker): Simplify. Fix comments.
9214 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9216 Introduce fast path for the widely used marker operation.
9217 * alloc.c (build_marker): New function.
9218 * lisp.h (build_marker): New prototype.
9219 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9220 * composite.c (autocmp_chars): Likewise.
9221 * editfns.c (buildmark): Remove.
9222 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9223 (save_restriction_save): Use build_marker.
9224 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9225 * window.c (save_window_save): Likewise.
9227 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9229 Do not use Fdelete_overlay in delete_all_overlays
9230 to avoid redundant calls to unchain_overlay.
9231 * buffer.c (drop_overlay): New function.
9232 (delete_all_overlays, Fdelete_overlay): Use it.
9233 * minibuf.c (get_minibuffer): Fix comment.
9235 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9237 Port to OpenBSD 5.1 amd64.
9238 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9239 This is needed for OpenBSD, and should be harmless on all BSD systems.
9240 Also, include <sys/sysctl.h>, as it should be available on all
9241 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9242 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9243 use p_pid member, not kp_proc.pid.
9245 2012-07-06 Glenn Morris <rgm@gnu.org>
9247 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9249 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9251 More xmalloc and related cleanup.
9252 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
9253 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
9254 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

9258 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
9259 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9260 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9262 Omit needless casts involving void * pointers and allocation.
9263 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9264 as the former is more robust if P's type is changed.
9265 Prefer xzalloc to xmalloc + memset 0.
9266 Simplify malloc-or-realloc to realloc.
9267 Don't worry about xmalloc returning a null pointer.
9268 Prefer xstrdup to xmalloc + strcpy.
9269 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9271 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9272 alloca of a constant.
9274 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9276 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9277 hscroll is larger than the line width. Fixes long and futile
9278 looping inside extend_face_to_end_of_line (on a TTY) producing
9279 glyphs that are not needed and thrown away.
9281 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9283 * marker.c (set_marker_restricted_both): Simplify by using
9286 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9288 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9290 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
9292 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
9293 not defined (Bug#11768).
9294 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9295 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9296 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9297 followed by gtk_box_set_homogeneous (Bug#11768).
9298 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9299 (update_theme_scrollbar_width, xg_create_scroll_bar):
9300 Use gtk_scrollbar_new (Bug#11768).
9301 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9302 (is_box_type): New function (Bug#11768).
9303 (xg_tool_item_stale_p): Call is_box_type.
9304 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9305 with default display (Bug#11768).
9307 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9309 * xdisp.c (window_hscroll_limited): New function.
9310 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9311 coordinates when window's hscroll is set to insanely large
9314 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9316 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9317 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
9319 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9322 * lisp.h (xzalloc): New prototype. Omit needless casts.
9323 * alloc.c (xzalloc): New function. Omit needless casts.
9324 * charset.c: Omit needless casts. Convert all calls to
9325 xmalloc with following memset to xzalloc.

9375 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9377 * fileio.c (time_error_value): Check the right error number.
9378 Problem reported by Troels Nielsen in
9379 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9381 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9383 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9384 This should be fixed in a better way; see Eli Zaretskii in
9385 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9386 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9388 * fileio.c (time_error_value): Rename from special_mtime.
9389 The old name's problems were noted by Eli Zaretskii in
9390 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9392 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9393 This variable's comment says Emacs needs at least one GDB-visible
9394 symbol of type enum pvec_type, to work around GDB problems.
9395 The symbol's value doesn't matter.
9397 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9398 that causes compilation to fail on pre-C99 compilers.
9400 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9402 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9403 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9405 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9407 * buffer.c (init_buffer_once): Fix initialization of
9408 headers for buffer_defaults and buffer_local_symbols.
9409 Reported by Juanma Barranquero <lekktu@gmail.com>.
9411 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9413 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9414 * lisp.h (enum pvec_type): Use fewer bits.
9415 (PSEUDOVECTOR_SIZE_BITS): New constant.
9416 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9417 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9418 change in pvec_type.
9419 (PSEUDOVECTOR_TYPEP): New macro.
9420 (TYPED_PSEUDOVECTORP): Use it.
9421 * fns.c (internal_equal): Adapt code to extract pvectype.
9422 * emacs.c (gdb_pvec_type): Update type.
9423 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9424 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9425 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9426 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9427 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9428 abusing vector->header.next.nbytes.
9429 (live_vector_p): Use PVEC_TYPE.
9430 (mark_object): Adapt code to extract pvectype. Use switch.
9432 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9434 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9435 Tighten new eassert a bit.
9437 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9439 Fix compilation with --enable-gcc-warnings and -O1
9441 * doprnt.c (doprnt): Change type of tem to int, initialize
9442 to avoid compiler warning. Add eassert.
9443 * search.c (simple_search): Initialize match_byte to avoid
9444 compiler warning. Add eassert.
9446 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9448 Avoid weird behavior with large horizontal scrolls.
9449 Without this change, for example, large hscroll values would
9450 mess up Emacs's display on Fedora 15 x86, presumably due to
9451 overflows in int calculations in the display code.
9452 Also, if buffers had long lines, Emacs would freeze.
9453 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9454 (set_window_hscroll): New function, containing the old guts of
9455 Fset_window_hscroll. Return the clipped value.
9456 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9457 This avoids the need to check against PTRDIFF_MAX.
9459 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9461 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9463 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9465 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9467 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9468 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9469 since GCC 4.4.6 issues a bogus warning for them.
9471 Fix bugs in file timestamp newness comparisons.
9472 * fileio.c (Ffile_newer_than_file_p):
9473 * lread.c (Fload): Use full timestamp resolution of files,
9474 not just the 1-second resolution, so that files that are only
9475 slightly newer still count as newer.
9476 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9477 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9479 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9481 * fileio.c: Improve handling of file time marker. (Bug#11852)
9482 (special_mtime): New function.
9483 (Finsert_file_contents, Fverify_visited_file_modtime):
9484 Use it to set special mtime values consistently.
9486 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9488 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9489 marker for non-existing file. (Bug#11852)
9491 2012-07-03 Glenn Morris <rgm@gnu.org>
9493 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9494 and did not make it into globals.h).
9496 2012-07-03 Tom Tromey <tromey@redhat.com>
9498 * window.c (Fset_window_margins, Fset_window_fringes)

9543 values which aren't power of 2.
9544 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9545 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users

9556 * alloc.c (allocate_vector_block): Remove redundant
9557 calls to mallopt if DOUG_LEA_MALLOC is defined.
9558 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9559 avoid calls to mallopt if zero_vector is returned.
9561 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9563 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9564 is enabled, avoid dereferencing NULL current_sblock if
9567 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9569 Cleanup basic buffer management.
9570 * buffer.h (struct buffer): Change layout to use generic vector
9571 marking code. Fix some comments. Change type of 'clip_changed'
9572 to bitfield. Remove unused #ifndef old.
9573 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9574 (GET_OVERLAYS_AT): Fix indentation.
9575 (for_each_per_buffer_object_at): New macro.

9579 * alloc.c (allocate_buffer): Adjust to match new layout of
9580 struct buffer. Fix comment.
9581 (mark_overlay): New function.

9583 Lisp area of struct buffer.
9584 (mark_object): Use it. Adjust marking of misc objects
9585 and related comments.
9587 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9589 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9590 wrapper that is not needed because the wrapped code is a no-op (zero
9591 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9592 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9594 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9596 * alloc.c (mark_buffer): Simplify. Remove prototype.
9597 (mark_object): Add comment. Reorganize marking of vector-like
9598 objects. Use CHECK_LIVE for all vector-like objects except buffers
9599 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9600 Avoid redundant calls to mark_vectorlike for bool vectors.
9602 2012-06-30 Glenn Morris <rgm@gnu.org>
9604 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9606 * epaths.in (PATH_SITELOADSEARCH): New.
9607 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9608 This is rather than relying on --enable-locallisppath elements
9609 having "site-lisp" in their names. (Bug#10208#25, 11658)
9611 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9613 * w32proc.c (sys_select): Accept and ignore one more argument.
9615 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9617 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9618 (pselect) [!MS_DOS]: Redirect to sys_select.
9620 * sysdep.c: Don't include dos.h and dosfns.h.
9622 * process.c (sys_select):
9623 * msdos.c (sys_select): Accept one more argument and ignore it.
9625 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9626 adapt data types and code to that.
9629 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9630 which clashes with the gnulib function of the same name.
9632 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9634 * font.c (font_style_to_value, font_style_symbolic)
9635 (font_prop_validate_style): Add type checks for values in
9638 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9640 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9643 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9645 * xdisp.c (try_window_id): Undo last change.
9647 * w32.c (getwd): Adjust commentary about startup_dir.
9648 (init_environment): Always call sys_access, even in non-MSVC
9649 builds. Don't chdir to the directory of the Emacs executable.
9650 This undoes code from 1997 which was justified by the need to
9651 "avoid conflicts when removing and renaming directories". But its
9652 downside was that every relative file name was being interpreted
9653 relative to the directory of the Emacs executable, which can never
9654 be TRT. In particular, it broke sys_access when called with
9655 relative file names.
9656 (sys_access): Map GetLastError to errno.
9658 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9660 * window.h (struct window): Change type of 'fringes_outside_margins'

9674 * charset.c (init_charset): Make lack of etc/charsets fatal.
9676 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9678 * editfns.c (region_limit): Fix type mismatch.
9680 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9682 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9683 undefined. Convert from xassert to eassert.
9684 * nsmenu.m: Convert from xassert to eassert.

9691 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9693 Avoid integer overflow on scroll-left and scroll-right.
9694 * window.c (HSCROLL_MAX): New macro.
9695 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

9700 * window.h (struct window): Change type of 'hscroll',
9701 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,

9703 Adjust users accordingly.
9704 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9705 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9706 from EMACS_INT to ptrdiff_t.

9713 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9715 * window.h (struct window): Change type of 'use_time' and

9782 * alloc.c (allocate_string): Omit intervals initialization.
9783 * alloc.c (make_uninit_multibyte_string): Initialize intervals

9842 a better opportunity to optimize away calls to strlen when the

9844 * image.c (imagemagick_error): Convert to build_string.
9845 * w32proc.c (sys_spawnve): Likewise.

9848 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9850 Use sprintf return value instead of invoking strlen on result.
9851 In the old days this wasn't portable, since some sprintf
9852 implementations returned char *. But they died out years ago and
9853 Emacs already assumes sprintf returns int.
9854 Similarly for float_to_string.
9855 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

9863 Use sprintf or float_to_string result to avoid need to call strlen.
9864 * data.c (Fnumber_to_string):
9865 Use make_unibyte_string, since the string must be ASCII.
9866 * lisp.h, print.c (float_to_string): Now returns int length.
9867 * term.c (produce_glyphless_glyph):
9868 Use sprintf result rather than recomputing it.
9870 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

9903 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

9906 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9908 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9909 instead of truncating it to 63 (admittedly a generous limit).
9911 * process.c: Fix spelling and caps in comments.
9913 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9915 * emacs.c (setpgrp): Remove definition, unused.

9969 * keyboard.c (kbd_buffer_get_event):
9970 * process.c (Faccept_process_output):

9973 when time_t is unsigned and as wide as intmax_t.
9974 See <http://bugs.gnu.org/9000#51>.

9993 Privately reported by Herbert J. Skuhra.
9994 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9996 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

10004 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10005 language ID in the event parameters.
10007 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10008 event.code, not the obscure "character set ID".
10010 2012-06-23 Chong Yidong <cyd@gnu.org>
10012 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10039 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10041 Support higher-resolution time stamps (Bug#9000).
10042 The time stamps are only nanosecond-resolution at the C level,
10043 since that's the best that any real-world system supports now.
10044 But they are picosecond-resolution at the Lisp level, as that's
10045 easy, and leaves room for future OS improvements.
10047 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10050 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10051 Don't get current time unless it's needed.
10053 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10054 now provides it if it's absent.
10055 (start_atimer): Port to higher-res time stamps.
10056 Check for time stamp overflow. Don't get current time more
10057 often than is needed.
10059 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10060 Include systime.h, not time.h.
10061 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10063 * dired.c: Include stat-time.h.
10064 (Ffile-attributes): File times now have higher resolution.
10066 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10067 (struct image): Timestamp now has higher resolution.
10069 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10070 has at least microseconds now. All uses removed.
10071 (update_frame, update_single_window, update_window, update_frame_1)
10072 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10073 (duration_to_sec_usec): Remove; no longer needed.
10075 * editfns.c (time_overflow): Now extern.
10076 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

10081 (decode_time_components, lisp_seconds_argument): New functions.
10082 (make_time): Now static.
10083 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10084 Report an error if the time is invalid, rather than having the caller
10087 * fileio.c: Include <stat-time.h>
10088 (Fcopy_file): Copy higher-resolution time stamps.
10089 Prefer to set the time stamp via a file descriptor if that works.
10090 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10091 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10092 (Fvisited_file_modtime, Fset_visited_file_modtime):
10093 Support higher-resolution time stamps.
10095 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10097 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10099 * image.c (prepare_image_for_display, clear_image_cache)
10100 (lookup_image): Port to higer-resolution time stamps.
10102 * keyboard.c (start_polling, bind_polling_period):
10103 Check for time stamp overflow.
10104 (read_char, kbd_buffer_get_event, timer_start_idle)
10105 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10106 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10107 Port to higher-resolution time stamps. Do not assume time_t is signed.
10108 (decode_timer): New function. Timers are now vectors of length 9,
10109 not 8, to accommodate the picosecond component.
10110 (timer_check_2): Use it.
10112 * nsterm.m (select_timeout, timeval_subtract): Remove.
10113 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10114 as they're a bit more accurate and handle overflow better.
10115 (ns_select): Change prototype to be compatible with pselect.
10116 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10117 * nsterm.h (ns_select): Adjust prototype.
10119 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10120 us-resolution time stamps.
10121 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10123 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10125 * lisp.h (time_overflow): New decl.
10126 (wait_reading_process_output): First arg is now intmax_t, not int,
10127 to accommodate larger waits.
10129 * process.h (struct Lisp_Process.read_output_delay):
10130 Now counts nanoseconds, not microseconds.
10131 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10133 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10134 (wait_reading_process_output):
10135 Port to ns-resolution time stamps.
10136 (Faccept_process_output, wait_reading_process_output):
10137 Check for time stamp overflow. Do not assume time_t is signed.
10138 (select_wrapper): Remove; we now use pselect.
10139 (Fprocess_attributes): Now generates ns-resolution time stamps.
10141 * sysdep.c: Include utimens.h. Don't include utime.h
10142 or worry about struct utimbuf; gnulib does that for us now.
10143 (gettimeofday): Remove; gnulib provides a substitute.
10144 (make_timeval): New function.
10145 (set_file_times): Now sets ns-resolution time stamps.
10146 New arg FD; all uses changed.
10147 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10148 (system_process_attributes):
10149 Now returns ns-resolution time stamp. All uses changed.
10150 Check for time stamp overflow.
10152 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10153 provides a substitute now.
10155 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10156 since it guarantees struct timespec.
10157 (EMACS_TIME): Now struct timespec, so that we can support
10158 ns-resolution time stamps.
10159 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10160 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10161 (EMACS_USECS): Remove.
10162 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10163 so multiply the arg by 1000 before storing it.
10164 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10166 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10167 Port to ns-resolution time stamps.
10168 (EMACS_TIME_NEG_P): Remove; replaced by....

10171 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10172 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10173 (make_timeval, make_lisp_time, decode_time_components): New decls.
10174 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10175 that it mishandled time_t overflow. You can't compare by subtracting!
10176 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10177 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10179 * term.c: Include <sys/time.h>.
10180 (timeval_to_Time): New function, for proper overflow wraparound.
10181 (term_mouse_position, term_mouse_click): Use it.
10183 * undo.c (record_first_change): Support higher-resolution time stamps
10184 in the undo buffer.
10185 (Fprimitive_undo): Use them when restoring time stamps.
10187 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10188 (w32_get_internal_run_time):
10189 Port to higher-resolution Emacs time stamps.
10190 (ltime): Now accepts single 64-bit integer, as that's more convenient
10193 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10195 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10196 for compatibility with pselect. Support ns-resolution time stamps.
10198 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10200 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10201 Check for time stamp overflow, and support ns-resolution time stamps.
10203 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10204 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10205 (timeval_subtract): Remove; no longer needed.
10206 (XTflash, XTring_bell, x_wait_for_event):
10207 Port to ns-resolution time stamps. Don't assume time_t is signed.
10209 2012-06-22 Chong Yidong <cyd@gnu.org>

10213 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10215 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10216 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10217 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10218 staticidx goes up to 1597 out of 1600 = 0x640.)
10220 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10222 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10223 Otherwise, the umask might be mistakenly 0 while handling input signals.
10225 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

10234 access to `contents' member of Lisp_Vector objects with AREF and ASET
10237 2012-06-19 Chong Yidong <cyd@gnu.org>
10239 * frame.c (delete_frame): When selecting a frame on a different
10240 text terminal, do not alter the terminal's top-frame.

10243 frame's selected window and its terminal's top-frame.
10244 (unwind_format_mode_line): Restore them.
10245 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10247 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

10256 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10257 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10258 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in

10266 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10268 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10269 gets killed during executing of this function (Bug#11665).
10270 Try to always return Qt when the buffer has been actually killed.
10271 (Vkill_buffer_query_functions): In doc-string say that functions
10272 run by this hook should not change the current buffer.
10274 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10276 Fix recently-introduced process.c problems found by static checking.
10277 * process.c (write_queue_push, write_queue_pop, send_process):
10278 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
10279 (write_queue_pop): Fix pointer signedness problem.
10280 (send_process): Remove unused local.
10282 2012-06-17 Chong Yidong <cyd@gnu.org>

10296 * lisp.h (eassert): Assume C89 or later.
10297 This removes the need for CHECK.
10298 (CHECK): Remove. Its comments about always evaluating its
10299 argument were confusing, as 'eassert' typically does not evaluate
10302 * coding.c (produce_chars): Use ptrdiff_t, not int.
10304 * xterm.c (x_draw_underwave): Check for integer overflow.
10305 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10448 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
10450 (XLI, XIL): Define.
10451 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
10453 * emacs.c (gdb_use_struct): Rename from gdb_use_union.

10457 * frame.c (delete_frame): Remove outdated comment.
10458 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
10459 USE_LISP_UNION_TYPE.
10460 (Fw32_unregister_hot_key): Likewise.

10462 * w32menu.c (add_menu_item): Likewise.

10478 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
10479 * alloc.c (make_number) [!defined make_number]:
10480 Remove, as lisp.h always defines this now.
10481 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
10482 (roundup_size): Verify that it is a power of 2.
10483 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):

10486 -DUSE_LSB_TAG=0, to override the automatically-selected default.
10487 USE_LSB_TAG now is always defined to be either 0 or 1.
10489 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
10490 code works fine either way, and efficiency is not a concern here,
10491 as the union type is for debugging, not for production.
10492 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10493 Use an inline function on all platforms when using the union type,
10494 since this is simpler and 'static inline' can be used portably
10496 (LISP_INITIALLY_ZERO): New macro.
10497 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
10498 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

10526 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
10527 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
10529 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>

10566 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
10567 dbus_type_is_basic if available.
10568 (xd_extract_signed, xd_extract_unsigned): Rename from
10569 extract_signed and extract_unsigned, respectively. Adapt callers.

10580 * xdisp.c (vmessage): Treat frame message as multibyte.
10581 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
10582 would generate the diagnostic "Making \302\247 buffer-local while
10585 2012-06-08 Eli Zaretskii <eliz@gnu.org>
10587 * dispnew.c (showing_window_margins_p): Undo last change, which
10588 was done due to an inadvertent commit.
10589 (adjust_frame_glyphs_for_frame_redisplay): Do call

10598 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
10600 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
10601 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
10603 2012-06-08 Eli Zaretskii <eliz@gnu.org>
10605 * alloc.c (allocate_vectorlike): Fix last change.
10607 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
10609 Block-based vector allocation of small vectors.
10610 * lisp.h (struct vectorlike_header): New field `nbytes',
10611 adjust comment accordingly.
10612 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10613 to denote vector blocks. Adjust users (live_vector_p,
10614 mark_maybe_pointer, valid_lisp_object_p) accordingly.

10636 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10638 * doprnt.c (doprnt): Truncate multibyte char correctly.
10639 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10640 would mishandle a string argument "Xc" if X was a multibyte
10641 character of length 2: it would truncate after X's first byte
10642 rather than including all of X.
10644 2012-06-06 Chong Yidong <cyd@gnu.org>
10646 * buffer.c (word_wrap): Doc fix.
10648 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

10677 Fbuffer_local_value; can return Qunbound.
10678 (Fbuffer_local_value): Use it.
10679 (Vmode_line_format): Docstring tweaks.

10693 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10695 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10696 Convert pctcpu and pctmem to Lisp float properly.
10697 Let the compiler fold better, as 100.0/0x8000 is exact.
10699 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10701 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10708 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10710 For a 'struct window', replace some Lisp_Object fields to
10711 bitfields where appropriate, remove unused fields.
10712 * window.h (struct window): Remove unused 'last_mark_x' and
10713 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10714 change its type from Lisp_Object to bitfield.
10715 Change type of 'force_start', 'optional_new_start',
10716 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10717 fields from Lisp_Object to bitfield. Adjust users accordingly.

10721 Pacify gcc -Wdouble-precision when using Xaw.
10722 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10723 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10724 Use 'float' consistently, rather than 'float' in most places
10725 and 'double' in a couple of places.
10727 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10729 * xdisp.c (handle_stop): Detect whether we have overlay strings
10730 loaded by testing it->current.overlay_string_index to be
10731 non-negative, instead of checking whether n_overlay_strings is
10732 positive. (Bug#11587)
10734 2012-05-31 Chong Yidong <cyd@gnu.org>
10736 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10742 * search.c (search_buffer): Remove calls to
10743 r_alloc_inhibit_buffer_relocation, as it is now called by
10744 maybe_unify_char, which was the cause of relocation of buffer text
10747 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10749 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10750 for the duration of call to load_charset, to avoid problems with
10751 callers of maybe_unify_char that access buffer text through C
10754 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10755 decrement the inhibition flag, instead of just setting or
10758 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10760 Remove obsolete '#define static' cruft.
10761 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10762 This #undef was "temporary" in 2000; it is no longer needed
10763 now that '#define static' has gone away.
10764 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10765 (gray_bitmap_bits): Remove; no longer needed.

10778 (safe_bcopy): Remove decl; no longer has that name.
10779 (main): Coalesce #if into single bit of code, for simplicity.
10780 Cast pointers to uintptr_t, since standard libraries want integers

10809 Do not create empty overlays with the evaporate property (Bug#9642).
10810 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10811 Bug#9642, but explicitly check that the buffer the overlay would
10812 be moved to is live and rearrange lines to make sure that errors
10813 will not put the overlay in an inconsistent state.
10814 (Fdelete_overlay): Cosmetics.
10816 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10818 * w32term.c (my_bring_window_to_top): New function.
10819 (x_raise_frame): Use handle returned by DeferWindowPos, which

10832 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10833 This avoids undefined behavior that might cause the eassert
10834 to not catch an out-of-range value.
10836 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10838 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

10853 Only r_alloc_inhibit_buffer_relocation needed to be added;
10854 the others were already declared.
10856 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10857 before checking whether it's out of range. Put the check inside
10859 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

10877 * search.c (search_buffer): Use it to inhibit relocation of buffer
10878 text while re_search_2 is doing its job, because re_search_2 is
10879 passed C pointers to buffer text. (Bug#11519)
10881 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10882 Update value to 24.
10884 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10885 state after an additional call to move_it_in_display_line_to, keep
10886 the values of it->max_ascent and it->max_descent found for the
10888 (pos_visible_p): Revert the comparison against bottom_y to what it

10894 Fix coding-related core dumps with gcc -ftrapv.
10895 The code was computing A - B, where A and B are pointers, and B is
10896 random garbage. This can lead to core dumps on platforms that
10897 have special pointer registers, and it also leads to core dumps on
10898 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10899 A - B only when B is initialized properly.
10900 * coding.c (coding_set_source, coding_set_destination): Return void.
10901 (coding_change_source, coding_change_destinations): New functions,
10902 with the old behaviors of coding_set_source and coding_set_destination.

10922 moves, call note_mouse_highlight. If help_echo changed, call
10923 gen_help_event to produce help-echo message in the echo area.
10924 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10927 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10929 * lread.c (read1): Simplify slightly to avoid an overflow warning
10930 with GCC 4.7.0 on x86-64.
10932 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10934 * bidi.c (bidi_mirror_char): Revert last change: an int is
10935 definitely wide enough here.
10937 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

10951 Use int, not EMACS_INT, where int is wide enough.
10952 (inhibit_garbage_collection, Fgarbage_collect):
10953 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10954 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10955 int might not be wide enough.

10971 (Foverlay_recenter, last_overlay_modification_hooks_used)
10972 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10973 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10974 (validate_region): Omit unnecessary test for b <= e,
10975 since that's guaranteed by the previous test.
10976 (adjust_overlays_for_delete): Avoid pos + length overflow.
10977 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10978 (report_overlay_modification):
10979 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10980 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10981 Omit pointer cast, which isn't needed anyway, and doesn't work
10982 after the EMACS_INT -> ptrdiff_t change.
10983 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10984 * buffer.h: Adjust decls to match defn changes elsewhere.

10989 not int, to avoid needless 32-bit limit on 64-bit hosts.
10990 (exec_byte_code): Use tighter memory-full test, one that checks
10991 for alloca overflow. Don't compute the address of the object just
10992 before an array, as that's not portable. Use EMACS_INT, not
10993 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10994 * callint.c (Fcall_interactively):
10995 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10996 * callproc.c (call_process_kill, Fcall_process):
10997 Don't assume pid_t fits into an Emacs fixnum.

11008 (casify_object): Avoid integer overflow when overallocating buffer.
11009 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

11012 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11013 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

11016 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11017 For CCL_MapSingle, check that content and value are in int range.

11019 Check that Vcode_version_map_vector is a vector.
11020 (resolve_symbol_ccl_program): Check that vector header is in range.
11021 Always copy the vector, so that we can check its contents reliably
11022 now rather than having to recheck each instruction as it's being
11023 executed. Check that vector words fit in 'int'.
11024 (ccl_get_compiled_code, Fregister_ccl_program)
11025 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11026 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11027 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11028 contents are in range.
11029 (Fccl_execute_on_string): Check that status is in range.
11030 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11031 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11032 Accept and return EMACS_INT, not int, because callers can pass values
11033 out of 'int' range.

11039 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11040 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11041 avoid mishandling large integers.

11050 Remove now-unnecessary CHECK_NATNUMs.
11051 (Fdefine_charset_internal): Check ranges here, more carefully.
11052 Don't rely on undefined behavior with signed left shift overflow.
11053 Don't assume unsigned int fits into fixnum, or that fixnum fits
11054 into unsigned int. Don't require max_code to be a valid fixnum;
11055 that's not true for gb10830 4-byte on a 32-bit host. Allow
11056 invalid_code to be a cons, for the same reason. Require code_offset
11057 to be a character. Avoid int overflow if max_char is close
11059 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11060 this is intended anyway and avoids some undefined behavior.
11061 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11062 INDEX_TO_CODE_POINT, as that's what it expects.
11063 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11064 * charset.h (DECODE_CHAR): Return int, not unsigned;
11065 this is what was intended anyway, and it avoids undefined behavior.
11066 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11067 integer-overflow issues.
11068 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11069 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11070 where the argument is EMACS_INT, and this behavior is not intended.
11071 * chartab.c (Fmake_char_table, Fset_char_table_range)
11072 (uniprop_get_decoder, uniprop_get_encoder):
11073 Don't assume fixnum fits in int.
11074 * cmds.c (move_point): New function, that does the gist of
11075 Fforward_char and Fbackward_char, but does so while checking
11076 for integer overflow more accurately.
11077 (Fforward_char, Fbackward_char): Use it.
11078 (Fforward_line, Fend_of_line, internal_self_insert)
11079 (internal_self_insert):
11080 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11861 2012-05-14 Glenn Morris <rgm@gnu.org>

11868 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

11871 (report_error, report_error_1, make_hdr, copy_sym)
11872 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11873 Make arguments const char *, not char *, to avoid violations of C
11874 standard and to fix some AIX warnings reported by Gilles Pion.
11876 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11878 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11879 already have overlays loaded.
11880 (handle_single_display_spec): Before returning without displaying
11881 fringe bitmap, synchronize the bidi iterator with the main display
11882 iterator, by calling iterate_out_of_display_property.
11883 (iterate_out_of_display_property): Detect buffer iteration by
11884 testing that it->string is a Lisp string.
11885 (get_next_display_element): When the current object is exhausted,
11886 and there's something on it->stack, call set_iterator_to_next to
11887 proceed with what's on the stack, instead of returning zero.
11888 (set_iterator_to_next): If called at the end of a Lisp string,
11889 proceed to consider_string_end without incrementing string
11890 position. Don't increment display vector index past the end of
11891 the display vector. (Bug#11417)
11892 (pos_visible_p): Don't report a position visible when move_it_to
11893 stopped at the last line of window, which happens to be scanned
11894 backwards by the bidi iteration. (Bug#11464)
11896 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11898 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11899 and right-margin display specs even if the spec is invalid or we
11900 are on a TTY, and thus unable to display on the fringes.
11901 That's because the text with the property will not be displayed anyway,
11902 so we need to signal to the caller that this is a "replacing"
11903 display spec. This fixes display when the spec is invalid or we
11906 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11908 * unexaix.c (make_hdr): Fix typo in prototype.

11939 Update dependencies.
11941 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11943 * xgselect.c (xg_select): Put maxfds+1 into a var.
11944 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11946 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11948 2012-05-10 Dave Abrahams <dave@boostpro.com>

11955 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11956 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11957 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11958 Initialize xd_registered_buses.
11960 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11962 Untag more efficiently if USE_LSB_TAG.
11963 This is based on a proposal by YAMAMOTO Mitsuharu in
11964 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11965 For an admittedly artificial (nth 8000 longlist) benchmark on
11966 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11967 Emacs's overall text size by 1%.
11968 * lisp.h (XUNTAG): New macro.
11969 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11970 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11971 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11972 * eval.c (Fautoload):
11973 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11974 * frame.h (XFRAME): Use XUNTAG.
11976 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11977 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11978 Remove unportable assumptions about print widths of types like
11980 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11981 intptr_t when converting between pointer and integer, to avoid GCC
11982 warnings about wrong width.
11984 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11986 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11987 stack for each reader_thread, instead of defaulting to 8MB
11988 determined by the linker. This avoids failures in creating
11989 subprocesses on Windows 7, see the discussion in this thread:
11990 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11992 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11994 Fix up display of the *Minibuf-0* buffer in the mini window.
11995 * keyboard.c (read_char): Don't clear the echo area if there's no
11997 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11998 contents of *Minibuf-0*) if there's no message displayed in its stead.
12000 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12002 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12005 2012-05-06 Chong Yidong <cyd@gnu.org>
12007 * lisp.mk (lisp): Update.
12009 2012-05-05 Jim Meyering <meyering@redhat.com>
12011 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12013 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12015 * data.c (PUT_ERROR): New macro.
12016 (syms_of_data): Use it. Add new error type `user-error'.
12017 * undo.c (user_error): New function.
12018 (Fprimitive_undo): Use it.
12019 * print.c (print_error_message): Adjust print style for `user-error'.
12020 * keyboard.c (user_error): New function.
12021 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12023 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12025 Do not limit current-time-string to years 1000..9999.
12026 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12027 (Fcurrent_time_string): Support any year that is supported by the
12028 underlying localtime representation. Don't use asctime, as it
12029 has undefined behavior for years outside the range -999..9999.
12031 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12033 Fix race conditions involving setenv, gmtime, localtime, asctime.
12034 Without this fix, interrupts could mess up code that uses these
12035 nonreentrant functions, since setting TZ invalidates existing
12036 tm_zone or tzname values, and since most of these functions return
12037 pointers to static storage.
12038 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12039 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12040 Grow the critical sections to include not just invoking
12041 localtime/gmtime, but also accessing these functions' results
12042 including their tm_zone values if any, and any related TZ setting.
12043 (format_time_string): Last arg is now struct tm *, not struct tm **,
12044 so that the struct tm is saved in the critical section.
12045 All callers changed. Simplify allocation of initial buffer, partly
12046 motivated by the fact that memory allocation needs to be outside
12047 the critical section.
12049 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12051 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12052 with RESET_INTERVAL.
12054 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12055 Remove duplicated buffer name initialization.
12057 2012-05-02 Jim Meyering <jim@meyering.net>
12059 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12061 * xfns.c (x_window): Use xstrdup (Bug#11375).
12063 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12065 * xdisp.c (pos_visible_p): If already at a newline from the
12066 display string before the 'while' loop, don't walk back the glyphs
12067 from it3.glyph_row. Solves assertion violation when the display
12068 string begins with a newline (egg.el). (Bug#11367)
12070 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12072 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12075 2012-05-01 Glenn Morris <rgm@gnu.org>
12077 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12078 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12079 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12080 All were removed before 23.1.
12082 * dispnew.c: Remove HAVE_LIBNCURSES test;
12083 it is always true on relevant platforms.
12085 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12086 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12088 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12090 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12092 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12093 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12096 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12098 Do not avoid creating empty evaporating overlays (Bug#9642).
12099 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12100 That is, do not delete an evaporating overlay if it becomes
12101 empty after its bounds are adjusted to fit within its buffer.
12102 This fix caused other problems, and I'm reverting it until we get
12103 to the bottom of them.
12105 2012-04-27 Chong Yidong <cyd@gnu.org>
12107 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12109 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12111 * xdisp.c (pos_visible_p): If the window start position is beyond
12112 ZV, start the display from buffer beginning. Prevents assertion
12113 violation in init_iterator when the minibuffer window is scrolled
12114 via the scroll bar.
12116 * window.c (window_scroll_pixel_based): Likewise.
12118 2012-04-27 Chong Yidong <cyd@gnu.org>
12120 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12122 2012-04-27 Glenn Morris <rgm@gnu.org>
12124 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12125 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12127 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12129 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12130 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12132 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12134 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12135 display element, check also the underlying string or buffer
12136 character. (Bug#11341)
12138 * w32menu.c: Include w32heap.h.
12139 (add_menu_item): If the call to AppendMenuW (via
12140 unicode_append_menu) fails, disable Unicode menus only if we are
12141 running on Windows 9X/Me.
12143 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12145 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12146 (xgetint): Add missing shift for LSB tags.
12148 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12150 * keyboard.c (read_char): Don't wipe echo area for select window
12151 events: These might get delayed via `mouse-autoselect-window'
12154 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12156 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12157 manipulation of :loaded-from data.
12159 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12161 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12162 now a cons (bug#11311).
12164 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12166 Do not create empty overlays with the evaporate property (Bug#9642).
12167 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12168 if it becomes empty after its bounds are adjusted to fit within
12169 its buffer. Without this fix, in a nonempty buffer (let ((o
12170 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12171 yields an empty overlay that has the evaporate property, which is
12172 not supposed to happen.
12174 Fix minor GTK3 problems found by static checking.
12175 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

12184 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12185 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)

12192 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12194 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12195 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12196 (__malloc_size_t, __malloc_ptrdiff_t):
12197 Remove. All uses removed, replaced by the definiens if needed,
12198 since we can assume C89 or better now.
12199 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12207 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12208 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12209 Define using prototypes, not old style.
12210 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):

12216 Omit no-longer-needed casts.
12217 (valloc): Use getpagesize, not __getpagesize.
12218 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
12219 (struct hdr): The 'magic' member is now size_t, not unsigned long.

12274 * alloc.c: Handle unusual debugging option combinations.
12275 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
12276 since the two debugging options are incompatible.
12277 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
12279 (mem_init, mem_insert, mem_insert_fixup):
12280 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

12290 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12291 Use Emacs indenting style more consistently. Avoid some casts.
12292 Use 'double' consistently rather than mixing 'float' and 'double'.
12294 2012-04-21 Eduard Wiebe <usenet@pusto.de>
12296 * sysdep.c (list_system_processes, system_process_attributes):

12331 row, return zero immediately.
12332 (try_cursor_movement): If inside continuation line, don't back up
12333 farther than the first row after the header line, if any.

12373 New extern decls, to avoid calling undeclared functions.
12374 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12375 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined

12378 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12379 Remove one incorrect comment and fix another.

12382 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
12383 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
12384 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
12385 (r_alloc_sbrk): Now static.
12387 Improve ralloc.c interface checking.
12388 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
12389 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
12390 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
12391 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)

12393 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
12394 Remove decls. This fixes an "It stinks!".
12396 * alloc.c (which_symbols): Fix alignment issue / type clash.
12398 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
12400 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
12401 (struct Lisp_Misc_Any): Likewise.
12402 (struct Lisp_Free): Likewise.
12403 * alloc.c (union aligned_Lisp_Symbol): Define.
12404 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
12405 aligned_Lisp_Symbol instead of struct Lisp_Symbol.

12411 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
12413 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
12414 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
12415 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12416 * s/netbsd.h, s/sol2-6.h:
12417 Remove definition of GC_MARK_STACK, since the default now works.
12418 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12419 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12420 no longer the default.
12421 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12423 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12425 * lread.c (lisp_file_lexically_bound_p):
12426 Fix hang at ";-*-\n" (bug#11238).
12428 2012-04-14 Eli Zaretskii <eliz@gnu.org>
12430 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
12431 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

12442 2012-04-13 Reuben Thomas <rrt@sc3d.org>
12444 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
12446 2012-04-11 Daniel Colascione <dancol@dancol.org>
12448 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12449 against is gone. It's better to use vfork now so that when Cygwin
12450 gains a new, working vfork, we use it automatically (bug#10398).
12452 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12470 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
12472 * w32.c (w32_delayed_load): Record the full path of the library
12473 being loaded (bug#10424).
12475 2012-04-09 Glenn Morris <rgm@gnu.org>
12477 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12478 not just in the obarray, before snarfing them. (Bug#11036)
12480 * Makefile.in ($(leimdir)/leim-list.el):
12481 Pass EMACS rather than BUILT_EMACS.
12483 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12485 * process.c (make_process):
12486 * process.h: Add integer `gnutls_handshakes_tried' member to

12493 (emacs_gnutls_read): Use new log functions,
12494 `gnutls_handshakes_tried' process member, and
12495 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12496 attempts per process (connection).
12498 2012-04-09 Chong Yidong <cyd@gnu.org>
12500 * eval.c (Fuser_variable_p, user_variable_p_eh)
12501 (lisp_indirect_variable): Functions deleted.
12502 (Fdefvar): Caller changed.
12504 * callint.c (Finteractive, Fcall_interactively):
12505 * minibuf.c (Fread_variable): Callers changed.
12507 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12509 * xdisp.c (set_cursor_from_row): If the display string appears in
12510 the buffer at position that is closer to point than the position
12511 after the display string, display the cursor on the first glyph of
12512 the display string. Fixes cursor display when a 'display' text
12513 property immediately follows invisible text. (Bug#11094)
12515 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12517 composite.c: use 'double' consistently
12518 * composite.c (get_composition_id): Use 'double' consistently
12519 instead of converting 'float' to 'double' and vice versa; this is
12520 easier to understand and avoids a GCC warning.
12522 2012-04-09 Glenn Morris <rgm@gnu.org>
12524 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12525 preparation for dumping it with emacs. (Bug#4789)
12526 (leimdir): New variable.
12527 ($(leimdir)/leim-list.el): New rule.
12528 (emacs$(EXEEXT)): Depend on leim-list.el.

12544 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12546 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12547 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12548 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12549 objects, as mark_maybe_pointer will catch them otherwise.
12550 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12551 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12558 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12560 Support building on MS-Windows with libxml2.
12562 * makefile.w32-in (OBJ2): Add xml.$(O).
12563 (GLOBAL_SOURCES): Add xml.c.
12564 ($(BLD)/xml.$(O)): New dependency list.
12566 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12567 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12568 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12569 [!WINDOWSNT]: New macros.
12570 (init_libxml2_functions, libxml2_loaded_p): New functions.
12571 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12572 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12573 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12574 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12576 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12577 Call init_libxml2_functions before calling libxml2 functions.
12578 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12580 * emacs.c: Don't include libxml/parser.h.
12581 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12582 xmlCleanupParser directly.
12584 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12586 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12588 * indent.c (Fvertical_motion): If there is a display string at
12589 point, use it.vpos to compute how many lines to backtrack after
12590 move_it_to point. (Bug#11133)
12592 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12594 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12595 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12596 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12597 macros related to unification of CJK characters. For the details,
12598 see the discussion following the message here:
12599 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12601 2012-04-04 Chong Yidong <cyd@gnu.org>
12603 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12605 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12607 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

12615 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12617 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12618 position we get to after a call to move_it_to fails the
12619 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12620 only if we wind up in a string from display property. (Bug#11063)
12622 * window.c (Fdelete_other_windows_internal): Invalidate the row
12623 and column information about mouse highlight, so that redisplay
12624 restores it after reallocating the glyph matrices. (Bug#7464)
12626 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12627 string comes from a `display' text property, use the buffer
12628 position of that property as if we actually saw that position in
12630 (move_it_by_lines): Remove the assertion that
12631 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12632 violated when there's a before-string at the beginning of a line.
12635 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12637 * xdisp.c (append_space_for_newline): If the default face was
12638 remapped, use the remapped face for the appended newline.
12639 (extend_face_to_end_of_line): Use the remapped default face for
12640 extending the face to the end of the line.
12641 (display_line): Call extend_face_to_end_of_line when the default
12642 face was remapped. (Bug#11068)
12644 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12646 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

12664 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12665 (command_loop_1): Use it; inhibit selection update for

12672 2012-03-25 Kenichi Handa <handa@m17n.org>
12674 * dispextern.h (struct glyph): Change the bit length of
12675 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12677 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12679 * s/ms-w32.h (tzname): Include time.h before redirecting to

12684 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12687 * xterm.c (XTread_socket): Only modify handling_signal if
12688 !SYNC_INPUT. (Bug#11080)
12690 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12692 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12693 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12694 when fetching a multibyte character consumes more bytes than
12695 CHAR_BYTES returns, due to unification of CJK characters in
12696 string_char. (Bug#11073)
12698 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12700 * process.c (wait_reading_process_output): Handle pty disconnect
12701 by refraining from sending oneself a SIGCHLD (bug#10933).
12703 2012-03-22 Chong Yidong <cyd@gnu.org>
12705 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12707 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

12735 that is not from display property, accept the row as a "cursor
12736 row" if one of the string's character has a non-nil `cursor'
12737 property. Fixes cursor positioning when there are newlines in
12738 overlay strings, e.g. in icomplete.el. (Bug#11035)
12740 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12742 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12744 2012-03-12 Chong Yidong <cyd@gnu.org>
12746 * eval.c (inhibit_lisp_code): Rename from
12747 inhibit_window_configuration_change_hook; move from window.c.
12749 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12750 * window.c (run_window_configuration_change_hook)
12751 (syms_of_window): Callers changed.
12753 2012-03-11 Chong Yidong <cyd@gnu.org>

12766 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
12768 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
12770 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12771 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12774 2012-03-03 Glenn Morris <rgm@gnu.org>
12776 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12778 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12784 (redisplay_window): Pass to move_it_vertically the margin in
12785 pixels, not in screen lines.
12787 2012-03-02 Glenn Morris <rgm@gnu.org>
12789 * buffer.c (buffer-list-update-hook): Doc fix.
12791 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12793 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12794 push_it before setting up the iterator for the first overlay
12795 string, even if we have an empty string loaded.
12796 (next_overlay_string): If there's an empty string on the iterator
12797 stack, pop the stack. (Bug#10903)
12799 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12801 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12802 Suggested by Stefan Monnier in
12803 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12804 * alloc.c (widen_to_Lisp_Object): New static function.
12805 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12806 and widening them to Lisp_Objects. This would work even if
12807 USE_LSB_TAG is defined and wide integers are used, which might
12808 happen in a future version of Emacs.
12810 2012-02-25 Chong Yidong <cyd@gnu.org>
12812 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12849 when computing $valmask.
12851 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12852 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12853 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12854 It's useless in that case, and it can cause problems on hosts
12855 that allocate halves of EMACS_INT values separately.
12856 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12857 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12858 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12859 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12860 it avoids undefined behavior on hosts where shifting right by more
12861 than the word width has undefined behavior.

13478 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13479 verifies glyph row's hash code--we have just reallocated the

13663 behave as if the cursor position were at the window margin.
13665 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13666 and the cursor position is out of bounds, behave as if the cursor
13667 position were at the window margin. (Bug#10075)
13669 2011-11-18 Chong Yidong <cyd@gnu.org>

13697 * dispnew.c (verify_row_hash): Call row_hash for computing the
13698 hash code of a row, instead of duplicating code from xdisp.c.
13700 * dispextern.h (row_hash): Add prototype.
13702 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

13808 The trivial performance wins aren't worth the portability hassles; see
13809 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13811 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13812 (window_box_width, window_box_left, window_box_left_offset)
13813 (window_box_right, window_box_right_offset): Undo previous change,
13814 by removing the "extern"s.
13815 * intervals.c (adjust_intervals_for_insertion)
13816 (adjust_intervals_for_deletion): Undo previous change,
13817 making these static again.
13818 (offset_intervals, temp_set_point_both, temp_set_point)
13819 (copy_intervals_to_string): No longer inline.
13820 * xdisp.c (window_text_bottom_y, window_box_width)
13821 (window_box_height, window_box_left_offset)
13822 (window_box_right_offset, window_box_left, window_box_right)
13823 (window_box): No longer inline.

13833 2011-11-07 Juanma Barranquero <lekktu@gmail.com>
13835 * lisp.h (syms_of_abbrev): Remove declaration.
13836 Reported by CHENG Gao <chenggao@royau.me>.
13838 2011-11-07 Eli Zaretskii <eliz@gnu.org>
13840 * w32.c (check_windows_init_file): Don't look for term/w32-win.el
13841 if Vpurify_flag is non-nil. Fixes a crash when running w32 build
13842 of temacs in GUI mode.
13844 2011-11-07 Martin Rudalics <rudalics@gmx.at>
13846 * window.h: Declare delete_all_child_windows instead of
13847 delete_all_subwindows.
13848 * window.c (Fwindow_nest, Fset_window_nest)
13849 (Fset_window_new_total, Fset_window_new_normal)
13850 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
13851 (delete_all_subwindows): Rename to delete_all_child_windows.
13852 (Fdelete_other_windows_internal, Fset_window_configuration):
13853 Call delete_all_child_windows instead of delete_all_subwindows.
13854 * frame.c (delete_frame): Call delete_all_child_windows instead
13855 of delete_all_subwindows.
13857 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
13859 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
13860 This is also needed for porting to any host where GC_MARK_STACK is
13861 not GC_MAKE_GCPROS_NOOPS.
13862 (which_symbols): Use it.
13864 2011-11-07 Kenichi Handa <handa@m17n.org>
13866 * coding.c (coding_set_destination): Check coding->src_pos only
13867 when coding->src_object is a buffer (bug#9910).

13877 * xmenu.c (cleanup_widget_value_tree): New function.
13878 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13879 calling free_menubar_widget_value_tree directly (Bug#9830).
13881 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
13883 Fix some portability problems with 'inline'.
13884 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13885 (window_box_width, window_box_left, window_box_left_offset)
13886 (window_box_right, window_box_right_offset): Declare extern.
13887 Otherwise, these inline functions do not conform to C99 and
13888 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13889 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13890 * intervals.c (adjust_intervals_for_insertion)
13891 (adjust_intervals_for_deletion): Now extern, because otherwise the
13892 extern inline functions 'offset_intervals' couldn't refer to it.
13893 (static_offset_intervals): Remove.
13894 (offset_intervals): Rewrite using the old contents of
13895 static_offset_intervals. The old version didn't conform to C99
13896 because an extern inline function contained a reference to an
13897 identifier with static linkage.
13899 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
13901 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

13907 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
13908 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
13909 return Qleft_to_right.
13911 2011-11-06 Chong Yidong <cyd@gnu.org>

13914 (Fminibuffer_window, Fwindow_buffer, Fwindow_splits)
13915 (Fset_window_splits, Fwindow_nest, Fset_window_nest)
13916 (Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
13917 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
13918 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
13919 (Fwindow_vscroll): Doc fix.
13920 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
13921 argument, since it makes no sense to pass a live window and for
13922 consistency with window-child.

13949 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
13950 (unwind_create_frame): New function (Bug#9943).
13951 (Fx_create_frame): Restructure code to be more similar to the one in
13952 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
13953 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
13954 Move terminal->reference_count++ just before making the frame official
13957 * nsterm.m (x_free_frame_resources): New function.
13958 (x_destroy_window): Move code to x_free_frame_resources.
13960 * xfns.c (unwind_create_frame): Fix comment.
13961 (Fx_create_frame, x_create_tip_frame):
13962 Move terminal->reference_count++ just before making the frame
13963 official. Move initialization of image_cache_refcount and
13964 dpyinfo_refcount before calling init_frame_faces (Bug#9943).
13966 2011-11-05 Eli Zaretskii <eliz@gnu.org>
13968 Support MSVC build with newer versions of Visual Studio.
13969 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

14004 previous/next-single-property-change returns nil, treat that as
14005 the beginning or the end of the buffer. (Bug#9955)
14007 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
14009 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

14132 (w32font_open_internal, compute_metrics):
14133 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14134 instead of calling the "wide" APIs directly.

14205 next_en_pos is over-stepped.
14207 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14209 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14210 * editfns.c: Rewrite current-time-zone so that it invokes
14211 the equivalent of (format-time-string "%Z") to get the time zone name.
14212 This fixes a bug when the time zone name contains characters that
14213 need converting from the system time locale to Emacs internal format.
14214 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14215 that patch fixed format-time-string to do the conversion, but
14216 I forgot to fix current-time-zone.
14217 (format_time_string): New function, containing most of
14218 what Fformat_time_string used to contain.
14219 (Fformat_time_string): Rewrite in terms of format_time_string.
14220 This doesn't change this function's behavior.
14221 (current-time-zone): Rewrite to use format_time_string.
14222 This fixes the bug reported by Michael Schierl in
14223 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14224 Jason Rumney's 2007-06-07 change worked around this bug, but
14226 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14228 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14230 * xdisp.c (start_display): If the character at POS is displayed
14231 via a display vector, reset IT->current.dpvec_index to zero.
14232 (try_window_reusing_current_matrix): If a line ends in a display
14233 vector or the next line starts in a display vector, continue
14234 redrawing the window even though the character position of
14235 start_row was reached.
14238 2011-10-18 Chong Yidong <cyd@gnu.org>
14240 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14241 with nobreak-char-display too.
14243 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14245 Fix part 3 of bug#9771.
14246 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14247 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14248 non-neutral characters if the current character is a paragraph
14249 separator (a.k.a. Newline). This avoids running the same
14250 expensive loop twice, once when we consume the preceding newline
14251 and the other time when the line actually needs to be displayed.
14252 Avoid the loop when we see neutrals on the base embedding level
14253 following a character whose directionality is the same as the
14254 paragraph's. This avoids running the expensive loop when a line
14255 ends in a long sequence of neutrals, like control characters.
14256 Add assertion against STRONG_AL type. Slightly rearrange code
14257 that determines the type of a neutral given the first non-neutral
14259 (bidi_level_of_next_char): Set next_en_pos to zero when
14260 invalidating its info.
14262 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14264 * xdisp.c (push_display_prop): Determine whether to record string
14265 or buffer position by IT->string, not by IT->method. Allow
14266 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14267 (move_it_vertically_backward): Don't look for character position
14268 immediately after the newline when in a continuation line.
14271 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14273 * window.c (coordinates_in_window): Rewrite and delabelize
14274 vertical border check. (Bug#5357) (Bug#9618)
14276 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14278 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14279 errors in XSetWindowBorder (bug#9310).
14281 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14283 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14284 avoid crash when xmalloc overrun checking is enabled.
14286 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14288 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14289 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14290 cursor motion with <left> and <right> arrow keys.
14292 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14293 some callers set that themselves.
14295 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14297 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14298 display string and the previous row comes from the same string and
14299 is empty. (Bug#9739) (Bug#9738)
14301 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14303 * doc.c (get_doc_string): Encode file name (bug#9735).
14305 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14307 * bidi.c (bidi_level_of_next_char):
14308 * xdisp.c (get_visually_first_element): Remove old incorrect
14309 comments regarding the Unicode Line Separator character.
14311 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14313 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14315 * alloc.c (Fgc_status): Do not access beyond zombies array
14316 boundary if nzombies > MAX_ZOMBIES.
14317 * alloc.c (dump_zombies): Add missing format specifier.
14319 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14321 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14322 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14324 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14325 Some packages use them to denote characters with modifiers.
14327 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14329 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14330 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14331 matching a pp-number. Rename parameter var to var1.
14333 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14335 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14337 2011-10-08 Glenn Morris <rgm@gnu.org>
14339 * callint.c (Fcall_interactively): Give a more explicit error for the
14340 'c' case with a non-character input. (Bug#8479)
14342 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14344 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14346 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14347 lines that are hscrolled on the left.
14349 * dispnew.c (buffer_posn_from_coords): Account for a possible
14350 presence of header-line. (Bug#4426)
14352 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14354 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14355 Don't advertise functionality which we discourage or doesn't work.
14357 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14359 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14360 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14361 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14362 this makes Emacs dump core during garbage collection on rare
14363 occasions. sizeof is obviously inferior to offsetof here, so
14364 stick with offsetof.
14365 (GC_POINTER_ALIGNMENT): New macro.
14366 (mark_memory): Omit 3rd (offset) arg; caller changed.
14367 Don't assume EMACS_INT alignment is the same as pointer alignment.
14369 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14371 * keyboard.c (read_key_sequence_remapped): New var.
14372 (read_key_sequence): Compute remapping in the right buffer.
14373 (command_loop_1): Use read_key_sequence's remapping directly.
14375 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14377 * dired.c (file_name_completion): Don't expand file name.
14378 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14379 before checking file name handler.
14381 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14382 they've been requested explicitly (bug#9591).
14384 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14386 * keymap.c (Fsingle_key_description): Use make_specified_string
14387 instead of build_string to build string from push_key_description.
14390 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14392 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14393 This fixes a Y2038 bug on 64-bit hosts.
14394 * buffer.c (reset_buffer):
14395 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14396 (Fclear_buffer_auto_save_failure):
14397 Use 0, not -1, to represent an unset failure time, since time_t
14398 might not be signed.
14400 Remove dependency on glibc malloc internals.
14401 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14402 Move back here from lisp.h, but with their new implementations.
14403 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14404 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14405 * charset.c (charset_table_init): New static var.
14406 (syms_of_charset): Use it instead of xmalloc. This removes a
14407 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14408 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14409 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14410 Move back to alloc.c.
14411 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14412 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14414 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14416 * nsterm.m (windowDidResize): Call x_set_window_size only when
14417 ns_in_resize is true. Otherwise set pixelwidth/height and
14418 call change_frame_size (Bug#9628).
14420 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14422 Port --enable-checking=all to Fedora 14 x86-64.
14423 * charset.c (syms_of_charset): Also account for glibc malloc's
14424 internal overhead when calculating the initial malloc maximum.
14426 Port --enable-checking=all to Fedora 14 x86.
14427 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14429 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14430 (overrun_check_realloc, overrun_check_free):
14431 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14432 That way, xmalloc returns a properly-aligned pointer even if
14433 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14434 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14435 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14436 into account when calculating the initial malloc maximum.
14437 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14438 Move here from alloc.c, so that charset.c can use it too.
14439 Properly align; the old code wasn't right for common 32-bit hosts
14440 when configured with --enable-checking=all.
14441 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14442 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14444 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14446 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14449 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14451 * xdisp.c (compute_display_string_end): If there's no display
14452 string at CHARPOS, return -1.
14454 * bidi.c (bidi_fetch_char): When compute_display_string_end
14455 returns a negative value, treat the character as a normal
14456 character not covered by a display string. (Bug#9624)
14458 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14460 * lread.c (Fread_from_string): Fix typo in docstring.
14462 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14464 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14465 newline, reseat the iterator instead of bidi-iterating there one
14466 character at a time. (Bug#9610)
14467 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14468 TO_CHARPOS if the bidi iterator is at base embedding level.
14470 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14472 * lread.c (readevalloop): Use correct code for NBSP.
14473 (read1): Likewise. (Bug#9608)
14475 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14477 * dbusbind.c (Fdbus_register_signal): When service is not
14478 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14480 2011-09-25 Glenn Morris <rgm@gnu.org>
14482 * buffer.c (truncate-lines): Doc fix.
14484 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14486 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14487 (Fset_window_next_buffers): Doc fix.
14489 2011-09-24 Glenn Morris <rgm@gnu.org>
14491 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14493 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14495 Fix minor problems found by static checking.
14496 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14497 * indent.c (Fvertical_motion): Fix == vs = typo.
14499 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14501 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14502 Default value is now t. Doc fix.
14504 * indent.c (Fvertical_motion): Compute and apply the overshoot
14505 logic when moving up, not only when moving down. Fix the
14506 confusing name and values of the it_overshoot_expected variable;
14507 logic changes accordingly. (Bug#9254) (Bug#9549)
14509 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14510 CHARPOS is covered by a display string which includes newlines.
14511 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14512 is covered by a display string with embedded newlines.
14514 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14516 * dbusbind.c (Fdbus_register_signal): Add match rule to
14517 Vdbus_registered_objects_table. (Bug#9581)
14518 (Fdbus_register_method, Vdbus_registered_objects_table):
14521 2011-09-24 Jim Meyering <meyering@redhat.com>
14523 do not ignore write error for any output size
14524 The previous change was incomplete.
14525 While it makes emacs --batch detect the vast majority of stdout
14526 write failures, errors were still ignored whenever the output size is
14527 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14528 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14529 && echo FAIL: ignored write error
14530 FAIL: ignored write error
14531 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14532 && echo FAIL: ignored write error
14533 FAIL: ignored write error
14534 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14536 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14538 * emacs.c (Fkill_emacs): In noninteractive mode exit
14539 non-successfully if a write error occurred on stdout. (Bug#9574)
14541 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14543 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14546 * dispextern.h (struct it): Update the comment documenting what
14549 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14551 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14552 a display string, extend search for cursor position to end of row.
14553 (find_row_edges): If the row ends in a newline from a display
14554 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14555 Handle the case of a display string with multiple newlines.
14556 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14557 non-empty line. Fixes confusing cursor motion with arrow keys at
14558 the beginning of a line that starts with whitespace.
14560 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14562 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14565 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14567 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14568 boolean (Bug#9154).
14570 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14572 * xdisp.c (display_line): Record maximum and minimum buffer
14573 positions even if no glyphs were produced (e.g., by a zero-width
14574 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14575 buffer positions that will be removed from the glyph row because
14577 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14578 column is beyond frame width: don't subtract 1 "pixel" when
14579 computing width of the stretch.
14580 (reseat_at_next_visible_line_start): Undo the change made on
14581 2011-09-17 that saved paragraph information and restored it after
14582 the call to `reseat'. (Bug#9545)
14584 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14586 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14587 and turn window cursor on if cleared (Bug#9415).
14589 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14591 * search.c (boyer_moore): Take unibyte characters from pattern
14592 literally. (Bug#9458)
14594 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14596 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14598 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14600 Fix minor problem found by static checking.
14601 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14602 initialized, to pacify gcc -Wuninitialized.
14604 * fileio.c: Report proper errno when syscall falls.
14605 (Finsert_file_contents): Save and restore errno,
14606 so that report_file_error outputs the correct diagnostic.
14607 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14609 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14611 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14613 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14615 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14616 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14618 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14620 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14621 about the current paragraph and restore it after the call to reseat.
14623 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14624 (bidi_find_paragraph_start): Search back for paragraph beginning
14625 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14626 (bidi_move_to_visually_next): Only trigger paragraph-related
14627 computations when the last character is a newline or at EOB, not
14628 just any NEUTRAL_B. (Bug#9470)
14630 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14631 truncated lines if point is covered by a display string. (Bug#9524)
14633 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14635 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14636 (cons_to_x_long): New function.
14637 (lisp_data_to_selection_data): Use it. Correct the test for
14638 short-versus-long data; it was negated. Break out of vector
14639 loop, for efficiency, when a long datum is discovered.
14641 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14643 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14645 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14647 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14648 GCC PR/17406) by declaring this function with external scope.
14650 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

14657 * editfns.c (Fformat): Correctly handle text properties on "%%".
14659 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14661 * xterm.c (x_draw_composite_glyph_string_foreground):

14663 * term.c (encode_terminal_code):
14664 * composite.c (composition_update_it, get_composition_id):
14665 * xdisp.c (get_next_display_element)
14666 (fill_composite_glyph_string): Add comments about special meaning
14667 of TAB characters in a composition.
14669 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14671 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14672 This occurs when processing a multibyte format.
14673 Problem reported by Wolfgang Jenker.
14675 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14677 * xdisp.c (try_cursor_movement): Only check for exact match if
14678 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14680 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14682 Remove unused external symbols.
14683 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14684 * xdisp.c (calc_pixel_width_or_height): Now static.
14685 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14686 * indent.c (check_display_width):
14687 * w32term.c: Fix comment to match code.
14688 * xterm.c, xterm.h (x_catching_errors): Remove.
14690 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14692 * xselect.c: Use signed conversions more consistently (Bug#9498).
14693 (selection_data_to_lisp_data): Assume incoming selection data are
14694 signed integers, not unsigned. This is to be consistent with
14695 outgoing selection data, which was modified to use signed integers
14696 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14697 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14698 expects long, not unsigned long.

14702 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14703 computation of loop end. Reported by Johan Bockgård
14706 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14708 * frame.c (Fother_visible_frames_p): Function deleted.
14710 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14712 * indent.c (compute_motion): Process display vector front to back
14713 rather than the other way around. (Bug#2496)
14715 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14717 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14719 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14721 * minibuf.c (Fread_from_minibuffer): Doc fix.
14723 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14725 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14726 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14728 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14730 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14731 value for non-existent files.
14733 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14735 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14736 set its "size" to -1. This will set the modtime_size field of
14737 the corresponding buffer to -1, which is what
14738 verify-visited-file-modtime expects for files that do not exist.
14741 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14743 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14745 * lisp.h: ... from here. push_key_description is no longer
14746 defined in keyboard.c, so its declaration should not be in
14747 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14748 logically belongs with push_key_description.
14750 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14752 * buffer.h: Include <sys/types.h> instead of <time.h>.
14753 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14754 Problem reported by Herbert J. Skuhra.
14756 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14758 * xml.c (parse_region): Make the parsing work for
14759 non-comment-starting XML files again (bug#9144).
14761 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14763 * image.c (gif_load): Fix calculation of bottom and right corner.
14766 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14768 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14769 redisplay in small windows.
14771 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14773 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14775 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14777 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14778 Operate on live windows only.
14780 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14782 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14784 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14786 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14787 only under bidi iteration.
14789 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14791 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14793 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14795 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14796 Without this fix, the command to link temacs failed due to an
14797 undefined symbol __builtin_isnan. This is because
14798 /usr/include/iso/math_c99.h #defines isnan(x) to
14799 __builtin_isnan(x), but the bundled gcc, which identifies itself
14800 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14802 * floatfns.c (isnan): #undef, and then #define to a clone of
14804 (Fisnan): Always define, since it's always available now.
14805 (syms_of_floatfns): Always define isnan at the Lisp level.
14807 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14809 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14811 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14813 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14814 The previous code assumed that file offsets (off_t values) fit in
14815 EMACS_INT variables, which is not true on typical 32-bit hosts.
14816 The code messed up by falsely reporting buffer overflow in cases
14817 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14818 when "big" contains more than 2**29 bytes, even though this
14819 inserts just one byte and does not overflow the buffer.
14820 (Finsert_file_contents): Store file offsets as off_t
14821 values, not as EMACS_INT values. Check for overflow when
14822 converting between EMACS_INT and off_t. When checking for
14823 buffer overflow or for overlap, take the offsets into account.
14824 Don't use EMACS_INT for small values where int suffices.
14825 When checking for overlap, fix a typo: ZV was used where
14826 ZV_BYTE was intended.
14827 (Fwrite_region): Don't assume off_t fits into 'long'.
14828 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14830 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14832 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14834 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14836 sprintf-related integer and memory overflow issues (Bug#9412).
14838 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14839 (esprintf, exprintf, evxprintf): New functions.
14840 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14841 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14842 (modify_event_symbol): Do not assume that the length of
14843 name_alist_or_stem is safe to alloca and fits in int.
14844 (Fexecute_extended_command): Likewise for function name and binding.
14845 (Frecursion_depth): Wrap around reliably on integer overflow.
14846 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14847 since some callers pass EMACS_INT values.
14848 (Fsingle_key_description): Don't crash if symbol name contains more
14849 than MAX_ALLOCA bytes.
14850 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14851 (get_minibuffer): Arg is now EMACS_INT, not int.
14852 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14853 (esprintf, exprintf, evxprintf): New decls.
14854 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14856 * dbusbind.c (signature_cat): New function.
14857 (xd_signature, Fdbus_register_signal):
14858 Do not overrun buffer; instead, report string overflow.
14860 * dispnew.c (add_window_display_history): Don't overrun buffer.
14861 Truncate instead; this is OK since it's just a log.
14863 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14864 even if the time zone offset is outlandishly large.
14865 Don't mishandle offset == INT_MIN.
14867 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14868 when creating daemon; the previous buffer-overflow check was incorrect.
14870 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14871 which has the guts of the old verror function.
14873 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14874 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14876 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14877 (font_unparse_xlfd): Don't blindly alloca long strings.
14878 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14879 fits in int, when using sprintf. Use single snprintf to count
14880 length of string rather than counting it via multiple sprintfs;
14881 that's simpler and more reliable.
14882 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14883 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14884 sprintf, in case result does not fit in int.
14886 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14887 (fontset_from_font): Print it.
14889 * frame.c (tty_frame_count): Now printmax_t, not int.
14890 (make_terminal_frame, set_term_frame_name): Print it.
14891 (x_report_frame_params): In X, window IDs are unsigned long,
14892 not signed long, so print them as unsigned.
14893 (validate_x_resource_name): Check for implausibly long names,
14894 and don't assume name length fits in 'int'.
14895 (x_get_resource_string): Don't blindly alloca invocation name;
14896 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14899 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14900 (xg_check_special_colors, xg_set_geometry):
14901 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14903 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14904 Use esprintf, not sprintf, in case result does not fit in int.
14906 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14907 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14908 it as a large positive number.
14909 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14910 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14912 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14913 in case result does not fit in int.
14915 * print.c (float_to_string): Detect width overflow more reliably.
14916 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14917 buffer overrun. Don't assume list length fits in 'int'. Treat
14918 print length of 0 as 0, not as infinity; to be consistent with other
14919 uses of print length in this function. Don't overflow print length
14920 index. Don't assume hash table size fits in 'long', or that
14921 vectorlike size fits in 'unsigned long'.
14923 * process.c (make_process): Use printmax_t, not int, to format
14924 process-name gensyms.
14926 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14928 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14929 to avoid potential buffer overrun.
14931 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14932 if X resource line is longer than 512 bytes.
14934 * xfns.c (x_window): Make sprintf buffer a bit bigger
14935 to avoid potential buffer overrun.
14937 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14939 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14941 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14943 Integer overflow fixes for scrolling, etc.
14944 Without these, Emacs silently mishandles large integers sometimes.
14945 For example, "C-u 4294967297 M-x recenter" was treated as if
14946 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14948 * xdisp.c (try_window_id): Check Emacs fixnum range before
14949 converting to 'int'.
14951 * window.c (window_scroll_line_based, Frecenter):
14952 Check that an Emacs fixnum is in range before assigning it to 'int'.
14953 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14954 values converted from Emacs fixnums.
14955 (Frecenter): Don't wrap around a line count if it is out of 'int'
14956 range; instead, treat it as an extreme value.
14957 (Fset_window_configuration, compare_window_configurations):
14958 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14960 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14961 that can exceed INT_MAX. Check that EMACS_INT value is in range
14962 before assigning it to the (possibly-narrower) index.
14963 (match_limit): Don't assume that a fixnum can fit in 'int'.
14965 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14968 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14969 (Fvertical_motion): Don't wrap around LINES values that don't fit
14970 in 'int'. Instead, treat them as extreme values. This is good
14971 enough for windows, which can't have more than INT_MAX lines anyway.
14973 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14975 * Require libxml/parser.h to avoid compilation warning.
14977 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14979 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14980 since this reportedly can destroy thread storage.
14982 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14984 * syntax.c (find_defun_start): Update all cache variables if
14985 exiting early (Bug#9401).
14987 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14989 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14991 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14992 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14993 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14995 * term.c (tty_append_glyph): New function.
14996 (produce_stretch_glyph): Static function and its prototype deleted.
14998 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15001 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15003 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15004 when checking :margin (Bug#9390).
15005 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15006 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15007 so that the name doesn't mislead. All uses changed.
15009 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15011 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15014 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15016 * xdisp.c (move_it_to): Don't bail out early when reaching
15017 position beyond to_charpos, if we are scanning backwards.
15018 (move_it_vertically_backward): When DY == 0, make sure we get to
15019 the first character in the line after the newline.
15021 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15023 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15024 (ccl_driver): Do not generate an out-of-range pointer.
15025 (Fccl_execute_on_string): Remove unnecessary check for
15026 integer overflow, noted by Stefan Monnier in
15027 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15028 Remove a FIXME that didn't need fixing.
15029 Simplify the newly-introduced buffer reallocation code.
15031 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15033 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15035 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15037 Integer and memory overflow issues (Bug#9196).
15039 * doc.c (get_doc_string): Rework so that
15040 get_doc_string_buffer_size is the actual buffer size, rather than
15041 being 1 less than the actual buffer size; this makes xpalloc more
15044 * image.c (x_allocate_bitmap_record, cache_image):
15045 * xselect.c (Fx_register_dnd_atom):
15046 Simplify previous changes by using xpalloc.
15048 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15049 since either will do and ptrdiff_t is convenient with xpalloc.
15051 * charset.c (charset_table_size)
15052 (struct charset_sort_data.priority): Now ptrdiff_t.
15053 (charset_compare): Don't overflow if priorities differ greatly.
15054 (Fsort_charsets): Don't assume list length fits in int.
15055 Check for size-calculation overflow when allocating sort data.
15056 (syms_of_charset): Allocate an initial charset table that is
15057 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15059 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15061 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15062 The actual value is always <= INT_MAX, and leaving it unsigned made
15063 overflow checking harder.
15065 * dispextern.h (struct glyph_matrix.rows_allocated)
15066 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15067 with xpalloc. The values are still always <= INT_MAX.
15069 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15071 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15072 (SAFE_NALLOCA): New macro.
15074 * region-cache.c (struct boundary.pos, find_cache_boundary)
15075 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15076 (set_cache_region, invalidate_region_cache)
15077 (revalidate_region_cache, know_region_cache, region_cache_forward)
15078 (region_cache_backward, pp_cache):
15079 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15080 so that ptrdiff_t * can be passed to xpalloc.
15081 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15082 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15083 (pp_cache): Don't assume cache_len fits in int.
15084 * region-cache.h: Adjust extern decls to match.
15086 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15087 EMACS_INT, since either will do, for xpalloc.
15089 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15090 (xnmalloc, xnrealloc, xpalloc): New functions.
15092 * bidi.c (bidi_shelve_header_size): New constant.
15093 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15094 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15096 * bidi.c (bidi_cache_shrink):
15097 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15099 Don't update size of array until after memory allocation succeeds,
15100 because xmalloc/xrealloc may not return.
15101 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15102 now that we have proper integer overflow checking.
15103 (record_overlay_string, overlay_strings): Catch overflows when
15104 calculating size of overlay_str_buf.
15106 * callproc.c (Fcall_process): Check for size overflow when
15107 calculating size of args2.
15108 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15109 Normally we prefer signed values, but sticking with ptrdiff_t would
15110 require adding more-complicated checks.
15112 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15113 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15114 Redo buffer-overflow calculations to avoid integer overflow.
15115 Add a FIXME comment where memory seems to be over-allocated.
15117 * character.c (Fstring): Check for size-calculation overflow.
15119 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15120 unnecessary integer overflow. Check for size overflow.
15121 (encode_coding_object): Don't update size until xmalloc succeeds.
15123 * composite.c (get_composition_id): Check for overflow in glyph
15124 length calculations.
15126 Integer and memory overflow fixes for display code.
15127 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15128 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15129 (scrolling_window): Check for overflow in size calculations.
15130 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15131 Don't assume glyph table len fits in int.
15132 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
15133 (row_table_size): Now ptrdiff_t, not int.
15134 (scrolling_window): Avoid overflow in size calculations.
15135 Don't update size until allocation succeeds.
15136 * fns.c (concat): Check for overflow in size calculations.
15137 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15138 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15139 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15141 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15142 (get_doc_string): Check for size calculation overflow.
15143 Don't update size until allocation succeeds.
15144 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15145 EMACS_INT, where ptrdiff_t will do.
15146 (Fsubstitute_command_keys): Check for string overflow.
15148 * editfns.c (set_time_zone_rule): Don't assume environment length
15150 (message_length): Now ptrdiff_t, not int.
15151 (Fmessage_box): Don't update size until allocation succeeds.
15152 Don't assume message length fits in int.
15153 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15155 * emacs.c (main): Do not reallocate argv, since there is a null at
15156 the end that can be overwritten, and this way there's no need to

15275 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15276 sizes, since they can exceed INT_MAX in size. Check for size

15286 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15287 (X_LONG_MIN): New macros.
15288 Use them to make the following changes clearer.
15289 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

15292 (SELECTION_QUANTUM): Remove, replacing with ...
15293 (selection_quantum): ... new function, which avoids overflow.
15295 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

15313 Don't store size until memory allocation succeeds.
15314 (x_get_window_property): Plug memory leak on memory exhaustion.
15315 Don't double-block input; malloc is safe here. Don't assume 2**34
15316 - 4 fits in unsigned long. Add an xassert to check
15317 XGetWindowProperty overflow. Be more careful about overflow
15318 calculations, and distinguish size from memory overflow better.

15325 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15326 result parameters unless successful. Rely on cons_to_unsigned
15327 to report problems with elements; the old code wasn't right anyway.
15328 (x_check_property_data): Check for int overflow; we cannot use
15329 a wider type due to X limits.

15362 * lisp.h (hash_lookup, hash_put):
15363 * minibuf.c (Ftest_completion):
15364 Use ptrdiff_t for hash table indexes, not int (which is too
15365 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15366 32-bit --with-wide-int hosts).
15368 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15369 Add a FIXME comment about memory leaks.

15398 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15399 (x_send_scroll_bar_event): Likewise. Check that the size does not
15400 exceed limits imposed by XClientMessageEvent, as well as the usual
15401 ptrdiff_t and size_t limits.

15404 (make_lispy_movement): Use same integer type in forward decl
15405 that is used in the definition.
15406 (read_key_sequence, keyremap_step):
15407 Change bufsize argument back to int, undoing my 2011-03-30 change.
15408 We prefer signed types, and int is wide enough here.
15409 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15410 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15411 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15412 length, not size_t. Use ptrdiff_t for index, not int.
15413 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15414 possibility of integer overflow.

15442 Prefer int to unsigned where either will do.
15443 (tiff_handler): New function, combining the cores of the
15444 old tiff_error_handler and tiff_warning_handler.
15445 This function is rewritten to use vsnprintf and thereby avoid
15446 stack buffer overflows. It uses only the features of vsnprintf
15447 that are common to both POSIX and native Microsoft.
15448 (tiff_error_handler, tiff_warning_handler): Use it.
15449 (tiff_load, gif_load, imagemagick_load_image):
15450 Don't assume :index value fits in 'int'.
15451 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15452 (imagemagick_load_image): Check that crop parameters fit into
15453 the integer types that MagickCropImage accepts. Don't assume
15454 Vimagemagick_render_type has a nonnegative value. Don't assume
15455 size_t fits in 'long'.
15456 (gs_load): Use printmax_t to print the widest integers possible.

15470 (handle_single_display_spec): If the display spec is of the form
15471 `(space ...)', and specifies display in the text area, return 2
15473 (try_cursor_movement): Check for the need to scroll more
15474 accurately, and prefer exact match for point under bidi.
15475 Don't advance `row' beyond the last row of the window.

15493 buffers, return left-to-right.
15494 (set_cursor_from_row): Consider candidate row a win if its glyph

15496 positioning on the newline at EOL of R2L text within L2R
15497 paragraph, and vice versa.
15498 (try_cursor_movement): Check continued rows, in addition to
15499 continuation rows. Fixes unwarranted scroll when point enters a
15500 continued line of R2L text within an L2R paragraph, or vice versa.
15501 (cursor_row_p): Consider the case of point being equal to
15502 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

15531 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15532 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15533 candidate is selected by the mouse, and that candidate has a
15534 composed character under the mouse.
15536 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15537 coordinates reported by pos-visible-in-window-p for a composed
15538 character in column zero.
15540 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15544 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15546 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15547 consider it a hit if to_charpos is anywhere in the range of the
15548 composed buffer positions.
15550 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15552 * image.c (gif_load): Don't assume that each subimage has the same
15553 dimensions as the base image. Handle disposal method that is
15554 "undefined" by the gif spec (Bug#9335).
15556 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15558 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15568 a composition, take its buffer position from IT->cmp_it.charpos.
15569 Fixes cursor positioning at the beginning of a line that begins
15570 with a composed character.
15572 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15574 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15575 character bidirectional type, use STRONG_L instead. Fixes crashes
15576 in a buffer produced by `describe-categories'.
15578 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15579 members before the level stack, so they would be saved and
15580 restored when copying iterator state. Fixes incorrect reordering
15581 around TABs covered by display properties.
15583 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

15593 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15595 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15596 has no `load' handler, try opening the file locally. (Bug#9311)
15598 2011-08-16 Ken Brown <kbrown@cornell.edu>
15600 * gmalloc.c: Expand comment.
15602 2011-08-16 Eli Zaretskii <eliz@gnu.org>
15604 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
15605 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
15607 2011-08-16 Ken Brown <kbrown@cornell.edu>
15609 Fix memory allocation problems in Cygwin build (Bug#9273).
15611 * unexcw.c ( __malloc_initialized): Declare external variable.
15612 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15614 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15616 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
15618 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
15619 in the static heap.
15620 [CYGWIN] (special_realloc): New function.
15621 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
15622 requests to realloc storage in the static heap.
15624 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
15626 * bidi.c (bidi_initialize): Remove unused local.
15628 2011-08-15 Eli Zaretskii <eliz@gnu.org>
15631 * biditype.h: Remove file.

15633 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
15635 * dispextern.h: Fix a typo in the comment to bidi_type_t.
15637 * chartab.c: Improve commentary for the uniprop_table API.
15639 * bidi.c (bidi_paragraph_init): Support zero value of
15640 bidi_ignore_explicit_marks_for_paragraph_level.
15641 (bidi_initialize): Use uniprop_table instead of including
15642 biditype.h and bidimirror.h.
15644 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
15645 coordinates of the iterator when restoring from ppos_it.
15648 2011-08-14 Kenichi Handa <handa@m17n.org>
15650 * process.c (create_process): Call setup_process_coding_systems
15651 after the pid of the process is set to -1 (Bug#8162).
15653 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15655 * xdisp.c (move_it_in_display_line_to): Don't invoke
15656 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15657 ppos_it. Fixes vertical cursor motion when line beginning is
15658 covered by an image. (Bug#9296)
15660 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15662 * nsterm.h (ns_run_ascript): Declare.
15663 (NSAPP_DATA2_RUNASSCRIPT): Define.
15665 * nsfns.m (as_script, as_result, as_status): New static variables.
15666 (ns_run_ascript): New function.
15667 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15668 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15669 the event loop. Get status from as_status (Bug#7276).
15671 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15672 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15673 the event loop (Bug#7276).
15675 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15677 * gnutls.c (QCgnutls_bootprop_priority)
15678 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
15679 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
15680 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
15681 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
15682 (QCgnutls_bootprop_verify_hostname_error)
15683 (QCgnutls_bootprop_callbacks_verify): Rename from
15684 Qgnutls_bootprop_..., all uses changed.
15686 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
15689 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
15691 * xfaces.c (Qframe_set_background_mode): Now static.
15692 * dispextern.h (Qframe_set_background_mode): Remove decl.

15696 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
15698 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15699 (Fnetwork_interface_list): Allocate in increments of bytes instead
15700 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15701 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15703 (struct ifflag_def): notrailers is smart on OSX.
15704 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15705 Get hardware address with getifaddrs if available.
15707 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15709 * xdisp.c (iterate_out_of_display_property): xassert that
15710 IT->position is set to within IT->object's boundaries. Break from
15711 the loop as soon as EOB is reached; avoids infloops in redisplay
15712 when IT->position is set up wrongly due to some bug.
15713 Set IT->current to match the bidi iterator unconditionally.
15714 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15715 entry. Force push_it to save on the stack the current
15716 buffer/string position, to be restored by pop_it. Fix flags in
15717 the iterator structure wrt the object coming from a display
15718 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15719 properties. (Bug#9284)
15721 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15723 * fontset.c (fontset_get_font_group): Add proper type checks.
15726 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15728 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
15729 and LC_VERSION_MIN_MACOSX.
15730 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
15731 (dump_it) [LC_FUNCTION_STARTS]: Use it.
15733 2011-08-08 Eli Zaretskii <eliz@gnu.org>
15735 * xdisp.c (forward_to_next_line_start): Allow to use the
15736 no-display-properties-and-no-overlays under bidi display.
15737 Set disp_pos in the bidi iterator to avoid searches for display
15738 properties and overlays.
15740 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15742 * editfns.c (Fset_time_zone_rule): Document relationship with the
15745 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
15746 the font entity extracted from the cache (Bug#8109).
15748 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15750 * composite.c (autocmp_chars): Don't reset point. That is done by
15751 restore_point_unwind (Bug#5984).
15753 2011-08-07 Juri Linkov <juri@jurta.org>
15755 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15756 to show the arg `TIME' instead of `TIMEVAL'.
15758 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15760 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15761 display property strides EOL and includes a newline, as in
15762 longlines-mode. (Bug#9254)
15763 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15764 word-wrap under bidirectional display. (Bug#9224)
15766 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15767 is non-zero, even if the data buffer is NULL. Fixes a crash in
15768 vertical-motion with longlines-mode. (Bug#9254)
15770 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15772 * bidi.c <bidi_cache_total_alloc>: Now static.
15773 (bidi_initialize): Initialize bidi_cache_total_alloc.
15775 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15778 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15779 amount allocated this far in `bidi_cache_total_alloc'.
15780 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15781 non-zero, only free the data buffer without restoring the cache
15782 contents. All callers changed.
15784 * dispextern.h (bidi_unshelve_cache): Update prototype.
15786 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15787 (move_it_in_display_line, move_it_to)
15788 (move_it_vertically_backward, move_it_by_lines): Replace the call
15789 to xfree to an equivalent call to bidi_unshelve_cache.
15790 (move_it_in_display_line_to): Fix logic of returning
15791 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15793 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15795 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15796 came from a string character with a `cursor' property. (Bug#9229)
15798 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15800 * Makefile.in (LIB_PTHREAD): New variable.
15801 (LIBES): Add LIB_PTHREAD (Bug#9216).
15803 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15804 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15806 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15808 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15810 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15812 * xterm.c (x_find_topmost_parent): New function.
15813 (x_set_frame_alpha): Find topmost parent window with
15814 x_find_topmost_parent and set the property there also (bug#9181).
15815 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15817 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15819 * callproc.c (Fcall_process): Avoid vfork clobbering
15820 the local vars buffer, coding_systems, current_dir.
15822 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15824 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15826 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15828 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15829 so that it is not optimized away.
15831 * xdisp.c (compute_display_string_pos): Remove unused local.
15833 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15835 Fix slow cursor motion and scrolling in large buffers with
15836 selective display, like Org Mode buffers. (Bug#9218)
15838 * dispextern.h (struct bidi_it): New member disp_prop_p.
15840 * xdisp.c: Remove one-slot cache of display string positions.
15841 (compute_display_string_pos): Accept an additional argument
15842 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15843 for a display string or property. If found, set DISP_PROP_P
15846 * bidi.c (bidi_fetch_char): Accept an additional argument
15847 DISP_PROP_P, and pass it to compute_display_string_pos.
15848 Only handle text covered by a display string if DISP_PROP_P is returned
15849 non-zero. All callers of bidi_fetch_char changed.
15851 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15853 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15855 2010-12-03 Don March <don@ohspite.net>
15857 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15858 last character M-[char] is translated to ESC [char] (bug#7541).
15860 2011-08-02 Kenichi Handa <handa@m17n.org>
15862 * lisp.h (uniprop_table): Extern it.
15864 * chartab.c (uniprop_table): Make it non-static.
15866 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15868 * xdisp.c (forward_to_next_line_start): Accept additional argument
15869 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15871 (reseat_at_next_visible_line_start): Use the bidi iterator state
15872 returned by forward_to_next_line_start to restore the state of
15873 it->bidi_it after backing up to previous newline. (Bug#9212)
15875 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15877 * regex.c (re_comp): Protoize.
15878 (re_exec): Fix return type.
15879 (regexec): Fix type of `ret'. (Bug#9203)
15881 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15883 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15884 This is needed if max-image-size is a floating-point number.
15886 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15888 * print.c (print_object): Print empty symbol as ##.
15890 * lread.c (read1): Read ## as empty symbol.
15892 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15894 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15895 setting frame foreground color (Bug#9175).
15896 (x_set_background_color): Likewise.
15898 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15899 contents (Bug#9176).
15900 (EmacsTooltip -init): Remove bezels and add shadows to
15903 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15904 or scroll bar (Bug#8470).
15906 * nsfont.m (nsfont_open): Remove assignment to voffset and
15907 unnecessary vars hshink, expand, hd, full_height, min_height.
15908 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15910 * nsterm.h (nsfont_info): Remove voffset field.
15912 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15914 Implement strike-through and overline on NextStep (Bug#8863).
15916 * nsfont.m (nsfont_open): Use underline position provided by font,
15917 instead of hard-coded value of 2.
15918 (nsfont_draw): Call ns_draw_text_decoration instead.
15920 * nsterm.h: Add declaration for ns_draw_text_decoration.
15922 * nsterm.m (ns_draw_text_decoration): New function for drawing
15923 underline, overline, and strike-through.
15924 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15925 ns_draw_text_decoration. Change treatment of cursor drawing to
15926 accommodate underlining, etc.
15928 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15930 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15933 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15935 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15936 Without this fix, if a signal arrives just after memory fills up,
15937 'malloc' might be invoked reentrantly.
15939 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15940 In other words, assume that every image size is allowed, on non-X
15941 hosts. This assumption is probably wrong, but it lets Emacs compile.
15943 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15945 * regex.c (re_iswctype): Convert return values to boolean.
15947 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15949 * xdisp.c (compute_display_string_pos): Don't use cached display
15950 string position if the buffer had its restriction changed.
15953 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15955 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15957 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15959 Integer signedness and overflow and related fixes. (Bug#9079)
15961 * bidi.c: Integer size and overflow fixes.
15962 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15963 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15964 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15965 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15966 (bidi_find_other_level_edge):
15967 Use ptrdiff_t instead of EMACS_INT where either will do.
15968 This works better on 32-bit hosts configured --with-wide-int.
15969 (bidi_cache_ensure_space): Check for size-calculation overflow.
15970 Use % rather than repeated addition, for better worst-case speed.
15971 Don't set bidi_cache_size until after xrealloc returns, because it
15973 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15974 (bidi_cache_ensure_space): Also check that the bidi cache size
15975 does not exceed that of the largest Lisp string or buffer. See Eli
15976 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15978 * alloc.c (__malloc_size_t): Remove.
15979 All uses replaced by size_t. See Andreas Schwab's note
15980 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15982 * image.c: Improve checking for integer overflow.
15983 (check_image_size): Assume that f is nonnull, since
15984 it is always nonnull in practice. This is one less thing to
15985 worry about when checking for integer overflow later.
15986 (x_check_image_size): New function, which checks for integer
15987 overflow issues inside X.
15988 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15989 This removes the need for a memory_full check.
15990 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15991 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15992 (xbm_read_bitmap_data): Change locals back to 'int', since
15993 their values must fit in 'int'.
15994 (xpm_load_image, png_load, tiff_load):
15995 Invoke x_create_x_image_and_pixmap earlier,
15996 to avoid much needless work if the image is too large.
15997 (tiff_load): Treat overly large images as if
15998 x_create_x_image_and_pixmap failed, not as malloc failures.
15999 (gs_load): Use x_check_image_size.
16001 * gtkutil.c: Omit integer casts.
16002 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16003 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16005 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16007 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16008 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16009 would wrongly return t on a 64-bit host.
16011 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16012 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16013 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16014 and therefore cause GCC to emit a bogus diagnostic in some cases.
16016 * image.c: Integer signedness and overflow and related fixes.
16017 This is not an exhaustive set of fixes, but it's time to
16018 record what I've got.
16019 (lookup_pixel_color, check_image_size): Remove redundant decls.
16020 (check_image_size): Don't assume that arbitrary EMACS_INT values
16021 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16022 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16023 (tiff_load, imagemagick_load_image):
16024 Check for overflow in size calculations.
16025 (x_create_x_image_and_pixmap): Remove unnecessary test for
16026 xmalloc returning NULL; that can't happen.
16027 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16028 (xpm_color_bucket): Use better integer hashing function.
16029 (xpm_cache_color): Don't possibly over-allocate memory.
16030 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16031 (gif_memory_source):
16032 Use ptrdiff_t, not int or size_t, to record sizes.
16033 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16034 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16035 either works, as we prefer signed integers.
16036 (tiff_read_from_memory, tiff_write_from_memory):
16037 Return tsize_t, not size_t, since that's what the TIFF API wants.
16038 (tiff_read_from_memory): Don't fail simply because the read would
16039 go past EOF; instead, return a short read.
16040 (tiff_load): Omit no-longer-needed casts.
16041 (Fimagemagick_types): Don't assume size fits into 'int'.
16043 Improve hashing quality when configured --with-wide-int.
16044 * fns.c (hash_string): New function, taken from sxhash_string.
16045 Do not discard information about ASCII character case; this
16046 discarding is no longer needed.
16047 (sxhash-string): Use it. Change sig to match it. Caller changed.
16048 * lisp.h: Declare it.
16049 * lread.c (hash_string): Remove, since we now use fns.c's version.
16050 The fns.c version returns a wider integer if --with-wide-int is
16051 specified, so this should help the quality of the hashing a bit.
16053 * emacs.c: Integer overflow minor fix.
16054 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16055 Define only if GNU_LINUX.
16056 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16058 * dispnew.c: Integer signedness and overflow fixes.
16059 Remove unnecessary forward decls, that were a maintenance hassle.
16060 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16062 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16063 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16064 (prepare_desired_row, line_draw_cost):
16065 Use int, not unsigned, where either works.
16066 (save_current_matrix, restore_current_matrix):
16067 Use ptrdiff_t, not size_t, where either works.
16068 (init_display): Check for overflow more accurately, and without
16069 relying on undefined behavior.
16071 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16072 Remove, replacing with the new symbols in lisp.h. All uses changed.
16073 * fileio.c (make_temp_name):
16074 * filelock.c (lock_file_1, lock_file):
16075 * xdisp.c (message_dolog):
16076 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16077 Use pMd etc. instead.
16078 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16079 replacing the pWIDE etc. symbols removed from editfns.c.
16081 * keyboard.h (num_input_events): Now uintmax_t.
16082 This is (very slightly) less likely to mess up due to wraparound.
16085 * buffer.c: Integer signedness fixes.
16086 (alloc_buffer_text, enlarge_buffer_text):
16087 Use ptrdiff_t rather than size_t when either will do, as we prefer
16090 * alloc.c: Integer signedness and overflow fixes.
16091 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16092 (__malloc_size_t): Default to size_t, not to int.
16093 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16094 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16095 Prefer ptrdiff_t to size_t when either would do, as we prefer
16097 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16098 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16099 Now const. Initialize with values that are in range even if char
16101 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16102 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16103 These functions do the right thing with sizes > 2**32.
16104 (check_depth): Now ptrdiff_t, not int.
16105 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16106 Adjust to new way of storing sizes. Check for size overflow bugs
16108 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16109 slightly wrong anyway, as it missed one instance of
16110 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16111 (refill_memory_reserve): Omit needless cast to size_t.
16112 (mark_object_loop_halt): Mark as externally visible.
16114 * xselect.c: Integer signedness and overflow fixes.
16115 (Fx_register_dnd_atom, x_handle_dnd_message):
16116 Use ptrdiff_t, not size_t, since we prefer signed.
16117 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16118 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16119 x_dnd_atoms_size and x_dnd_atoms_length.
16121 * doprnt.c: Prefer signed to unsigned when either works.
16123 * doprnt.c (doprnt):
16125 * xdisp.c (vmessage):
16126 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16127 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16128 prefer signed arithmetic to avoid comparison confusion.
16129 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16130 but is a bit tricky.
16132 Assume freestanding C89 headers, string.h, stdlib.h.
16133 * data.c, doprnt.c, floatfns.c, print.c:
16134 Include float.h unconditionally.
16135 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16136 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16137 * regex.c: Likewise for stddef.h, string.h.
16138 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16139 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16140 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16141 (STDC_HEADERS): Remove obsolete defines.
16142 * sysdep.c: Include limits.h unconditionally.
16144 Assume support for memcmp, memcpy, memmove, memset.
16145 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16146 * regex.c (memcmp, memcpy):
16147 Remove; we assume C89 now.
16149 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16150 (__malloc_safe_bcopy): Remove; no longer needed.
16152 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16153 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16154 well either way, and we prefer signed to unsigned.
16156 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16158 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16159 closes the connection while we're reading (bug#9182).
16161 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16163 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16164 are specified (Bug#9168).
16166 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16168 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16169 Found by GCC static checking and --with-wide-int on a 32-bit host.
16171 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16173 * xdisp.c (compute_display_string_pos): Fix logic of caching
16174 previous display string position. Initialize cached_prev_pos to
16175 -1. Fixes slow-down at the beginning of a buffer.
16177 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16179 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16180 for attrs[LFACE_FONTSET_INDEX].
16182 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16184 * xml.c (parse_region): Remove unused local
16185 that was recently introduced.
16187 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16189 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16190 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16192 * xdisp.c (move_it_in_display_line_to): Record the best matching
16193 position for TO_CHARPOS while scanning the line, and restore it on
16194 exit if none of the characters scanned was an exact match.
16195 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16196 when exact match is impossible due to invisible text, and the
16197 lines are truncated.
16199 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16201 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16204 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16206 Fix a significant slow-down of cursor motion with C-n, C-p,
16207 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16208 auto-repeat under bidi redisplay in fontified buffers.
16209 * xdisp.c (compute_stop_pos_backwards): New function.
16210 (next_element_from_buffer): Call compute_stop_pos_backwards to
16211 find a suitable prev_stop when we find ourselves before
16213 (reseat): Don't look for prev_stop, as that could mean a very long
16215 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16216 <cached_disp_overlay_modiff>: Cache for last found display string
16218 (compute_display_string_pos): Return the cached position if asked
16219 about the same buffer in the same area of character positions, and
16220 the buffer wasn't changed since the time the display string
16221 position was cached.
16223 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16225 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16226 is an integer, which is important for empty lines. (Bug#9149)
16228 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16230 * frame.c (Fmodify_frame_parameters): In tty case, update the
16231 default face if necessary (Bug#4238).
16233 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16235 * editfns.c (Fstring_to_char): No need to explain what a character
16236 is in the docstring (Bug#6576).
16238 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16240 * xml.c (parse_region): Make sure we always return a tree.
16242 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16244 * xml.c (parse_region): If a document contains only comments,
16247 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16249 * xml.c (make_dom): Return comments, too.
16251 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16254 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16255 and the surrounding thread.
16256 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16257 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16258 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16260 * s/openbsd.h (BROKEN_SIGIO): Define.
16261 * unexelf.c (unexec) [__OpenBSD__]:
16262 Don't update the .mdebug section of the Alpha COFF symbol table.
16264 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16266 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16269 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16271 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16272 This fixes some race conditions on the permissions of any newly
16275 * alloc.c (valid_pointer_p): Use pipe, not open.
16276 This fixes some permissions issues when debugging.
16278 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16279 If fchown fails to set both uid and gid, try to set just gid,
16280 as that is sometimes allowed. Adjust the file's mode to eliminate
16281 setuid or setgid bits that are inappropriate if fchown fails.
16283 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16285 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16286 to compare Lisp_Objects.
16287 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16288 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16289 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16291 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16293 * lread.c (read_integer): Unread even EOF character.
16294 (read1): Likewise. Properly record start position of symbol.
16296 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16297 symbol character follows.
16299 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16301 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16302 This works around a problem with the previous change to Fcopy_file.
16303 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16304 and without this change, GCC might complain about discarding
16305 fchown's return value.
16307 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16309 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16311 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16313 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16315 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16317 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16318 it's used from the C level.
16320 * process.c: Use the same condition for POLL_FOR_INPUT in both
16321 keyboard.c and process.c (bug#1858).
16323 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16325 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16326 (Fgnutls_boot): Use it.
16328 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16330 * doc.c (Fsubstitute_command_keys): Revert last change.
16332 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16334 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16335 quotes the next character, and doesn't affect other longer
16336 sequences (bug#8935).
16338 * lread.c (syms_of_lread): Clarify that is isn't only
16339 `eval-buffer' and `eval-defun' that's affected by
16340 `lexical-binding' (bug#8460).
16342 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16344 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16345 bidi redisplay when a line includes both an image and is truncated.
16347 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16349 Fix minor problems found by static checking.
16350 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16351 (elsz): Now a signed constant, not a size_t var. We prefer signed
16352 types to unsigned, to avoid integer comparison confusion. Without
16353 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16354 "cannot optimize loop, the loop counter may overflow", a symptom
16356 * indent.c (Fvertical_motion): Mark locals as initialized.
16357 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16359 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16361 * search.c (Fre_search_backward): Mention `case-fold-search' in
16362 all the re_search_* functions (bug#8138).
16364 * keyboard.c (Fopen_dribble_file): Document when the file is
16367 2011-07-14 Eli Zaretskii <eliz@gnu.org>
16369 * bidi.c (bidi_dump_cached_states): Fix format of displaying
16372 Support bidi reordering of display and overlay strings.

16375 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
16376 (reseat_to_string): Initialize bidi_it->string.s and
16377 bidi_it->string.schars.
16378 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16379 NULL (avoids a crash in bidi_paragraph_init).
16380 Initialize itb.string.lstring.
16381 (init_iterator): Call bidi_init_it only of a valid
16382 buffer position was specified. Initialize paragraph_embedding to
16384 (reseat_to_string): Initialize the bidi iterator.
16385 (display_string): If we need to ignore text properties of
16386 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16387 original value of -1 will not work with bidi.)
16388 (compute_display_string_pos): First arg is now struct
16389 `text_pos *'; all callers changed. Support display properties on
16391 (compute_display_string_end): Support display properties on Lisp
16393 (init_iterator, reseat_1, reseat_to_string): Initialize the
16394 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16395 when iterating on a string not from display properties).
16396 (compute_display_string_pos, compute_display_string_end):
16397 Fix calculation of the object to scan. Fixes an error when using
16399 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16400 base_level_stop; instead, set base_level_stop to BEGV.
16401 Fixes crashes in vertical-motion.
16402 (next_element_from_buffer): Improve commentary for when
16403 the iterator is before prev_stop.
16404 (init_iterator): Initialize bidi_p from the default value of
16405 bidi-display-reordering, not from buffer-local value. Use the
16406 buffer-local value only if initializing for buffer iteration.
16407 (handle_invisible_prop): Support invisible properties on strings
16408 that are being bidi-reordered.
16409 (set_iterator_to_next): Support bidi reordering of C strings and
16411 (next_element_from_string): Support bidi reordering of Lisp
16413 (handle_stop_backwards): Support Lisp strings as well.
16414 (display_string): Support display of R2L glyph rows.
16415 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16416 (init_iterator): Don't initialize it->bidi_p for strings
16418 (reseat_to_string): Initialize it->bidi_p for strings here.
16419 (next_element_from_string, next_element_from_c_string)
16420 (next_element_from_buffer): Add xassert's for correspondence
16421 between IT's object being iterated and it->bidi_it.string
16423 (face_before_or_after_it_pos): Support bidi iteration.
16424 (next_element_from_c_string): Handle the case of the first string
16425 character that is not the first one in the visual order.
16426 (get_visually_first_element): New function, refactored from common
16427 parts of next_element_from_buffer, next_element_from_string, and
16428 next_element_from_c_string.
16429 (tool_bar_lines_needed, redisplay_tool_bar)
16430 (display_menu_bar): Force left-to-right direction. Add a FIXME
16431 comment for making that be controlled by a user option.
16432 (push_it, pop_it): Save and restore the state of the
16433 bidi iterator. Save and restore the bidi_p flag.
16434 (pop_it): Iterate out of display property for string iteration as
16436 (iterate_out_of_display_property): Support iteration over strings.
16437 (handle_single_display_spec): Set up it->bidi_it for iteration
16438 over a display string, and call bidi_init_it.
16439 (handle_single_display_spec, next_overlay_string)
16440 (get_overlay_strings_1, push_display_prop): Set up the bidi
16441 iterator for displaying display or overlay strings.
16442 (forward_to_next_line_start): Don't use the shortcut if
16444 (back_to_previous_visible_line_start): If handle_display_prop
16445 pushed the iterator stack, restore the internal state of the bidi
16446 iterator by calling bidi_pop_it same number of times.
16447 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16448 and we are bidi-iterating, don't decrement the iterator position;
16449 instead, set the first_elt flag in the bidi iterator, to produce
16451 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16452 (push_display_prop): xassert that we are iterating a buffer.
16453 (push_it, pop_it): Save and restore paragraph_embedding member.
16454 (handle_single_display_spec, next_overlay_string)
16455 (get_overlay_strings_1, reseat_1, reseat_to_string)
16456 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16457 correctly. Don't assume unibyte strings are not bidi-reordered.
16458 (compute_display_string_pos)
16459 (compute_display_string_end): Fix handling the case of C string.
16460 (push_it, pop_it): Save and restore from_disp_prop_p.
16461 (handle_single_display_spec, push_display_prop): Set the
16462 from_disp_prop_p flag.
16463 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
16464 (pop_it): Call iterate_out_of_display_property only if we are
16465 popping after iteration over a string that came from a display
16466 property. Fix a typo in popping stretch info. Add an assertion
16467 for verifying that the iterator position is in sync with the bidi
16469 (handle_single_display_spec, get_overlay_strings_1)
16470 (push_display_prop): Fix initialization of paragraph direction for
16471 string when that of the parent object is not yet determined.
16472 (reseat_1): Call bidi_init_it to resync the bidi
16473 iterator with IT's position. (Bug#7616)
16474 (find_row_edges): If ROW->start.pos gives position
16475 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
16476 (handle_stop, back_to_previous_visible_line_start, reseat_1):
16477 Reset the from_disp_prop_p flag.
16478 (SAVE_IT, RESTORE_IT): New macros.
16479 (pos_visible_p, face_before_or_after_it_pos)
16480 (back_to_previous_visible_line_start)
16481 (move_it_in_display_line_to, move_it_in_display_line)
16482 (move_it_to, move_it_vertically_backward, move_it_by_lines)
16483 (try_scrolling, redisplay_window, display_line): Use them when
16484 saving a temporary copy of the iterator and restoring it back.
16485 (back_to_previous_visible_line_start, reseat_1)

16924 subseconds part to the entropy, as that's a bit more random.
16925 Prefer signed to unsigned, since the signedness doesn't matter and
16926 in general we prefer signed. When given a limit, use a
16927 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16928 latter isn't right if USE_2_TAGS_FOR_INTS.
16929 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16930 not 0..VALMASK. Don't discard "excess" bits that random () returns.
16932 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
16934 * textprop.c (text_property_stickiness):
16935 Obey Vtext_property_default_nonsticky.
16936 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.

16942 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16943 This is more efficient than Ffile_directory_p and avoids a minor race.
16945 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16947 * buffer.c (Foverlay_put): Say what the return value is
16950 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16951 is a directory before asking whether to use the file name
16953 (barf_or_query_if_file_exists): Make the "File is a directory"
16954 error be more correct.
16956 * fns.c (Frequire): Remove the mention of the .gz files, since
16957 that's installation-specific, but keep the mention of
16958 `get-load-suffixes'.
16960 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
16962 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.
16963 Report string overflow if the output is too long.
16965 2011-07-04 Juanma Barranquero <lekktu@gmail.com>
16967 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
16968 (syms_of_gnutls): Remove duplicate DEFSYM for
16969 Qgnutls_bootprop_verify_hostname_error, an error for
16970 Qgnutls_bootprop_verify_error (which is no longer used).
16972 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16973 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16974 Also (re)move comments that are misplaced or no longer relevant.
16976 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16978 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16982 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
16983 and background color parameters if they have been changed.

16996 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
16998 * keyboard.c (command_loop_1): If a down-mouse event is unbound,
16999 leave any prefix arg for the up event (Bug#1586).

17003 * lread.c (syms_of_lread): Mention single symbols defined by
17004 `defvar' or `defconst' (bug#7154).
17006 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17007 (Frequire): Mention get-load-suffixes.
17009 2011-07-02 Martin Rudalics <rudalics@gmx.at>

17075 * eval.c (struct backtrace): Simplify and port the data structure.
17076 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17077 signed bit field, as this assumption is not portable and it makes
17078 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17079 "char debug_on_exit : 1" as this is not portable either; instead,
17080 use the portable "unsigned int debug_on_exit : 1". Remove unused
17081 member evalargs. Remove obsolete comments about cc bombing out.
17083 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
17085 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

17153 (emacs_fixed_get_preferred_height): Use min_width/height from
17154 frames size_hint to set minimum and natural (Bug#8919).
17155 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17156 and use min_width/height from frames size_hint to set
17157 min_width/height (Bug#8919).

17250 (PRINTPREPARE, printchar, strout):
17251 Don't set size unless allocation succeeds.
17253 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17254 for sizes. Check for string overflow more accurately.

17269 to improve quality of diagnostics for out-of-range radices.
17270 Calculate buffer size correctly for out-of-range radices.
17271 (read1): Check for integer overflow in radices, and in
17272 read-circle numbers.
17273 (read_escape): Avoid int overflow.
17274 (Fload, openp, read_buffer_size, read1)
17275 (substitute_object_recurse, read_vector, read_list, map_obarray):

17298 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17299 The following patches are for when GLYPH_DEBUG && !XASSERT.
17300 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17301 * dispnew.c (flush_stdout):
17302 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17303 Mark as externally visible.
17304 * dispnew.c (check_window_matrix_pointers): Now static.
17305 * dispnew.c (window_to_frame_vpos):
17306 * xfns.c (unwind_create_frame):

17313 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17315 (debug_method_add): Use va_list and vsprintf rather than relying
17316 on undefined behavior with wrong number of arguments.
17317 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17318 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17319 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17320 since we're not interested in debugging glyphs with old libraries.
17321 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17322 GCC 4.6.0's static checking.
17324 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

17356 (Fnext_overlay_change, Fprevious_overlay_change)
17357 (mouse_face_overlay_overlaps, Foverlays_in):
17358 Use ptrdiff_t, not int, for sizes.
17359 (overlays_at, overlays_in): Check for size-calculation overflow.
17361 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17363 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17364 (x_session_initialize): Do not assume string length fits in int.
17366 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17367 This is unlikely, but can occur if DPI is outlandish.
17369 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17370 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17372 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17373 * xrdb.c (magic_file_p, search_magic_path):
17374 Omit last arg SUFFIX; it was always 0. All callers changed.
17375 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17377 * xfont.c (xfont_match): Avoid need for strlen.
17379 * xfns.c: Don't assume strlen fits in int.
17380 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17382 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17383 not unsigned long, as we prefer signed integers. All callers changed.
17384 Detect integer overflow in repeat count.
17385 (message_dolog): Don't assume print length fits in 39 bytes.
17386 (display_mode_element): Don't assume strlen fits in int.
17388 * termcap.c: Don't assume sizes fit in int and never overflow.
17389 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17390 (gobble_line): Check for size-calculation overflow.
17392 * minibuf.c (Fread_buffer):
17393 * lread.c (intern, intern_c_string):
17394 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17395 Don't assume string length fits in int.
17397 * keyboard.c (parse_tool_bar_item):
17398 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17400 * font.c: Don't assume string length fits in int.
17401 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17402 Use ptrdiff_t, not int.
17403 (font_intern_prop): Don't assume string length fits in int.
17404 Don't assume integer property fits in fixnum.
17405 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17407 * filelock.c: Fix some buffer overrun and integer overflow issues.
17408 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17409 Reformulate so as not to need the command string.
17410 Invoke gzip -cd rather than gunzip, as it's more portable.
17411 (lock_info_type, lock_file_1, lock_file):
17412 Don't assume pid_t and time_t fit in unsigned long.
17413 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17414 (current_lock_owner): Prefer signed type for sizes.
17415 Use memcpy, not strncpy, where memcpy is what is really wanted.
17416 Don't assume (via atoi) that time_t and pid_t fit in int.
17417 Check for time_t and/or pid_t out of range, e.g., via a network share.
17418 Don't alloca where an auto var works fine.
17420 * fileio.c: Fix some integer overflow issues.
17421 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17422 Don't assume string length fits in int.
17423 (directory_file_name): Don't assume string length fits in long.
17424 (make_temp_name): Don't assume pid fits in int, or that its print
17425 length is less than 20.
17427 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17429 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17431 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17433 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17434 We prefer signed integers, even for size calculations.
17436 * emacs.c: Don't assume string length fits in 'int'.
17437 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17438 (main): Don't invoke strlen when not needed.
17440 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17441 (XD_DEBUG_MESSAGE): Don't waste a byte.
17443 * callproc.c (getenv_internal_1, getenv_internal)
17444 (Fgetenv_internal):
17445 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17447 * lread.c (invalid_syntax): Omit length argument.
17448 All uses changed. This doesn't fix a bug, but it simplifies the
17449 code away from its former Hollerith-constant appearance, and it's
17450 one less 'int' to worry about when looking at integer-overflow issues.
17451 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17453 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17454 This didn't break anything, but it didn't help either.
17455 It's confusing to put a bogus integer in a place where the actual
17456 value does not matter.
17457 (LIST_END_P): Remove unused macro and its bogus comment.
17458 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17460 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17461 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17463 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17464 We prefer signed types, and the value cannot exceed the EMACS_INT
17465 range anyway (because otherwise the length would not be representable).
17466 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17467 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17468 This avoids a GCC warning when WIDE_EMACS_INT.
17470 * indent.c (sane_tab_width): New function.
17471 (current_column, scan_for_column, Findent_to, position_indentation)
17472 (compute_motion): Use it. This is just for clarity.
17473 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17475 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17477 * lisp.h (lint_assume): New macro.
17478 * composite.c (composition_gstring_put_cache):
17479 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17481 * editfns.c, insdel.c:
17482 Omit unnecessary forward decls, to simplify future changes.
17484 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17486 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17488 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17489 Use much-faster test for byte-length change.
17490 Don't assume string byte-length fits in 'int'.
17491 Check that character arg fits in 'int'.
17492 (mapcar1): Declare byte as byte, for clarity.
17494 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17496 * fns.c (concat): Catch string overflow earlier.
17497 Do not rely on integer wraparound.
17499 * dispextern.h (struct it.overlay_strings_charpos)
17500 (struct it.selective): Now EMACS_INT, not int.
17501 * xdisp.c (forward_to_next_line_start)
17502 (back_to_previous_visible_line_start)
17503 (reseat_at_next_visible_line_start, next_element_from_buffer):
17504 Don't arbitrarily truncate the value of 'selective' to int.
17506 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17508 * composite.c: Don't truncate sizes to 'int'.
17509 (composition_gstring_p, composition_reseat_it)
17510 (composition_adjust_point): Use EMACS_INT, not int.
17511 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17512 not EMACS_UINT, for indexes.
17514 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17516 * buffer.c: Include <verify.h>.
17517 (struct sortvec.priority, struct sortstr.priority):
17518 Now EMACS_INT, not int.
17519 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17520 (struct sortstr.size, record_overlay_string)
17521 (struct sortstrlist.size, struct sortlist.used):
17522 Don't truncate size to int.
17523 (record_overlay_string): Check for size-calculation overflow.
17524 (init_buffer_once): Check at compile-time, not run-time.
17526 2011-06-22 Jim Meyering <meyering@redhat.com>
17528 Don't leak an XBM-image-sized buffer
17529 * image.c (xbm_load): Free the image buffer after using it.
17531 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17534 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17535 that Sun C diagnosed.
17536 * fns.c (secure_hash): Fix pointer signedness issue.
17537 * intervals.c (static_offset_intervals): New function.
17538 (offset_intervals): Use it.
17540 2011-06-21 Leo Liu <sdl.web@gmail.com>
17543 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17546 * fns.c (secure_hash): Rename from crypto_hash_function and change
17547 the first arg to accept symbols.
17548 (Fsecure_hash): New primitive.
17549 (syms_of_fns): New symbols.
17551 2011-06-20 Deniz Dogan <deniz@dogan.se>
17553 * process.c (Fset_process_buffer): Clarify return value in
17556 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17558 * dispnew.c (add_window_display_history): Use BVAR.
17560 * xdisp.c (debug_method_add): Use BVAR.
17561 (check_window_end, dump_glyph_matrix, dump_glyph)
17562 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17564 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17567 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17568 check till after the cache is created in init_frame_faces.
17570 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17572 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17574 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17576 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17577 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17578 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17580 Improve buffer-overflow checking (Bug#8873).
17581 * fileio.c (Finsert_file_contents):
17582 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17583 Remove the old (too-loose) buffer overflow checks.
17584 They weren't needed, since make_gap checks for buffer overflow.
17585 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17586 The old code merely checked for Emacs fixnum overflow, and relied
17587 on undefined (wraparound) behavior. The new code avoids undefined
17588 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17590 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17591 Tune. Don't use wider integers than needed. Don't use alloca.
17592 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17594 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17596 * insdel.c, lisp.h (buffer_overflow): New function.
17597 (insert_from_buffer_1, replace_range, replace_range_2):
17598 * insdel.c (make_gap_larger):
17599 * editfns.c (Finsert_char):
17600 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17602 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17604 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17606 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17608 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17609 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17611 * fileio.c: Don't assume EMACS_INT fits in off_t.
17612 (emacs_lseek): New static function.
17613 (Finsert_file_contents, Fwrite_region): Use it.
17614 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17616 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17618 * fns.c: Don't overflow int when computing a list length.
17619 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17620 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17621 truncation on 64-bit hosts. Check for QUIT every
17622 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17623 faster and is responsive enough.
17624 (Flength): Report an error instead of overflowing an integer.
17625 (Fsafe_length): Return a float if the value is not representable
17626 as a fixnum. This shouldn't happen except in contrived situations.
17627 (Fnthcdr, Fsort): Don't assume list length fits in int.
17628 (Fcopy_sequence): Don't assume vector length fits in int.
17630 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17631 (header_size, word_size): New constants.
17632 (allocate_vectorlike): Don't check size overflow here.
17633 (allocate_vector): Check it here instead, since this is the only
17634 caller of allocate_vectorlike that could cause overflow.
17635 Check that the new vector's length is representable as a fixnum.
17637 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17638 The previous code was bogus. For example, next_almost_prime (32)
17639 returned 39, which is undesirable as it is a multiple of 3; and
17640 next_almost_prime (24) returned 25, which is a multiple of 5 so
17641 why was the code bothering to check for multiples of 7?
17643 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17645 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17647 Variadic C functions now count arguments with ptrdiff_t.
17648 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17649 Back then I didn't know that the Emacs coding style prefers signed int.
17650 Also, in the meantime I found a few more instances where arguments
17651 were being counted with int, which may truncate counts on 64-bit
17652 machines, or EMACS_INT, which may be unnecessarily wide.
17653 * lisp.h (struct Lisp_Subr.function.aMANY)
17654 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17655 Arg counts are now ptrdiff_t, not size_t.
17656 All variadic functions and their callers changed accordingly.
17657 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17658 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17659 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17660 * callint.c (Fcall_interactively): Check arg count for overflow,
17661 to avoid potential buffer overrun. Use signed char, not 'int',
17662 for 'varies' array, so that we needn't bother to check its size
17663 calculation for overflow.
17664 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17665 * eval.c (apply_lambda):
17666 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17667 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17668 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17670 * callint.c (Fcall_interactively): Don't use index var as event count.
17672 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17673 * mem-limits.h (SIZE): Remove; no longer used.
17675 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17677 Remove unnecessary casts.
17678 * xterm.c (x_term_init):
17679 * xfns.c (x_set_border_pixel):
17680 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17681 These aren't needed now that we assume ANSI C.
17683 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17684 It's more likely to cause problems (due to unsigned overflow)
17687 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17689 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17691 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17693 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17695 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17697 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17699 GLYPH_CODE_FACE returns EMACS_INT, not int.
17700 * dispextern.h (merge_faces):
17701 * xfaces.c (merge_faces):
17702 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17703 Don't assume EMACS_INT fits in int.
17705 * character.h (CHAR_VALID_P): Remove unused parameter.
17706 * fontset.c, lisp.h, xdisp.c: All uses changed.
17708 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17710 * fns.c (concat): Minor tuning based on overflow analysis.
17711 This doesn't fix any bugs. Use int to hold character, instead
17712 of constantly refetching from Emacs object. Use XFASTINT, not
17713 XINT, for value known to be a character. Don't bother comparing
17714 a single byte to 0400, as it's always less.
17716 * floatfns.c (Fexpt):
17717 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17719 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17722 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17724 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17725 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17726 incorrectly succeed when S was a string, because 4294967386 was
17727 truncated before it was used.
17729 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17730 Otherwise, an out-of-range integer could cause undefined behavior
17733 * composite.c: Use int, not EMACS_INT, for characters.
17734 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17735 EMACS_INT, for values that are known to be in character range.
17736 This doesn't fix any bugs but is the usual style inside Emacs and
17737 may generate better code on 32-bit machines.
17739 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17740 This is for reasons similar to the recent CHAR_STRING fix.
17741 * charset.c (Fencode_char): Check that character arg is actually
17742 a character. Pass an int to ENCODE_CHAR.
17743 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17744 wider than 'int', as a compile-time check to prevent future regressions
17747 * character.c (char_string): Remove unnecessary casts.
17749 Make sure a 64-bit char is never passed to CHAR_STRING.
17750 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17751 by silently ignoring the top 32 bits, allowing some values
17752 that were far too large to be valid characters.
17753 * character.h: Include <verify.h>.
17754 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17755 arguments are no wider than unsigned, as a compile-time check
17756 to prevent future regressions in this area.
17758 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17759 (Fsubst_char_in_region):
17761 * xdisp.c (decode_mode_spec_coding):
17762 Adjust to CHAR_STRING's new requirement.
17763 * editfns.c (Finsert_char, Fsubst_char_in_region):
17764 * fns.c (concat): Check that character args are actually
17765 characters. Without this test, these functions did the wrong
17766 thing with wildly out-of-range values on 64-bit hosts.
17768 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17769 These casts should not be needed on 32-bit hosts, either.
17770 * keyboard.c (read_char):
17771 * lread.c (Fload): Remove casts to unsigned.
17773 * lisp.h (UNSIGNED_CMP): New macro.
17774 This fixes comparison bugs on 64-bit hosts.
17775 (ASCII_CHAR_P): Use it.
17776 * casefiddle.c (casify_object):
17777 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17778 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17779 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17780 * dispextern.h (FACE_FROM_ID):
17781 * keyboard.c (read_char): Use UNSIGNED_CMP.
17783 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17784 not to EMACS_INT, to avoid GCC warning.
17786 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17788 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17789 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17790 isn't needed on 32-bit machines.
17792 * buffer.c (Fgenerate_new_buffer_name):
17793 Use EMACS_INT for count, not int.
17794 (advance_to_char_boundary): Return EMACS_INT, not int.
17796 * data.c (Qcompiled_function): Now static.
17798 * window.c (window_body_lines): Now static.
17800 * image.c (gif_load): Rename local to avoid shadowing.
17802 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17803 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17804 * alloc.c (make_save_value): Integer argument is now of type
17805 ptrdiff_t, not int.
17806 (mark_object): Use ptrdiff_t, not int.
17807 * lisp.h (pD): New macro.
17808 * print.c (print_object): Use it.
17810 * alloc.c: Use EMACS_INT, not int, to count objects.

17840 (allocate_string_data): Check for string overflow. This catches
17841 some instances we weren't catching before. Also, it catches
17842 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17843 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17844 and ptrdiff_t and EMACS_INT are both 64 bits.
17846 * character.c, coding.c, doprnt.c, editfns.c, eval.c:

18352 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18353 Do not assume that spare memory exists; that assumption is valid
18354 only if SYSTEM_MALLOC.
18355 (LARGE_REQUEST): New macro, so that the issue of large requests
18356 is separated from the issue of spare memory.

18425 instead of using explicit *_CHAR codes.
18426 (bidi_resolve_explicit, bidi_resolve_weak):

18435 (bidi_level_of_next_char): Don't try to lookup the cache for the
18436 next/previous character if nothing is cached there yet, or if we
18437 were just reseat()'ed to a new position.
18439 * xdisp.c (set_cursor_from_row): Set start and stop points
18440 according to the row's direction when priming the loop that looks
18441 for the glyph on which to display cursor.

18443 (display_prop_intangible_p): Reimplement to call
18444 handle_display_spec instead of single_display_spec_intangible_p.
18445 Accept 3 additional arguments needed by handle_display_spec.
18446 This fixes incorrect cursor motion across display property with complex
18447 values: lists, `(when COND...)' forms, etc.

18454 (compute_display_string_pos): Accept additional argument
18455 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18456 value of a `display' property is a "replacing spec".
18457 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18458 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18459 the display property, but just return a value indicating whether
18460 the display property will replace the characters it covers.
18461 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18462 frame_window_p members of struct bidi_it.
18463 (compute_display_string_pos, compute_display_string_end):

18486 All callers changed. (Bug#8762)
18488 * gnutls.c: Use Emacs's memory allocators.
18489 Without this change, the gnutls library would invoke malloc etc.
18490 directly, which causes problems on non-SYNC_INPUT hosts, and which
18491 runs afoul of improving memory_full behavior. (Bug#8761)
18492 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18493 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18494 xfree instead of the default malloc, realloc, free.
18495 (Fgnutls_boot): No need to check for memory allocation failure,
18496 since xmalloc does that for us.
18498 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

18518 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18519 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18520 * alloc.c (allocate_vectorlike):
18521 Check for overflow in vector size calculations.
18522 * ccl.c (ccl_driver):
18523 Check for overflow when converting EMACS_INT to int.

18525 need to be updated by these changes.
18526 * fns.c (make_hash_table, maybe_resize_hash_table):
18527 Check for integer overflow with large hash tables.
18528 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18529 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18530 (SXHASH_REDUCE): New macro.
18531 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18532 Use it instead of discarding useful hash info with large hash values.
18533 (sxhash_float): New function.
18534 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18535 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18536 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18537 Rewrite to use FIXNUM_BITS, as this simplifies things.
18538 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18539 Adjust signatures to match updated version of code.
18540 (consing_since_gc): Now EMACS_INT, since a single hash table can
18541 use more than INT_MAX bytes.

18590 Make it possible to run ./temacs.
18592 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18593 syms_of_callproc does the same thing. Remove test for

18654 * fns.c (to_uchar): Define.
18655 (crypto_hash_function): Use it to convert some newly-signed
18656 variables to unsigned, to avoid sign-extension bugs. For example,
18657 without this change, (md5 "truc") would evaluate to
18658 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18659 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in

18675 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18676 Use XFASTINT rather than XUINT when numbers are nonnegative.
18677 (xd_append_arg, Fdbus_method_return_internal):
18678 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18679 arguments, check that Lisp number is nonnegative, rather than
18680 silently wrapping negative numbers around. (Bug#8722)
18681 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18684 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18686 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18688 ccl: Add integer overflow checks.
18689 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18690 (IN_INT_RANGE): New macros.
18691 (ccl_driver): Use them to check for integer overflow when
18692 decoding a CCL program. Many of the new checks are whether XINT (x)
18693 fits in int; it doesn't always, on 64-bit hosts. The new version
18694 doesn't catch all possible integer overflows, but it's an
18695 improvement. (Bug#8719)
18697 * alloc.c (make_event_array): Use XINT, not XUINT.
18698 There's no need for unsigned here.
18700 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18701 This follows up to the 2011-05-06 change that substituted uintptr_t
18702 for EMACS_INT. This case wasn't caught back then.
18704 Rework Fformat to avoid integer overflow issues.
18705 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18706 now (part of C89). Include <verify.h>.
18707 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18708 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18709 (Fformat): Avoid the prepass trying to compute sizes; it was only
18710 approximate and thus did not catch overflow reliably. Instead, walk
18711 through the format just once, formatting and computing sizes as we go,
18712 checking for integer overflow at every step, and allocating a larger
18713 buffer as needed. Keep track separately whether the format is
18714 multibyte. Keep only the most-recently calculated precision, rather
18715 than them all. Record whether each argument has been converted to
18716 string. Use EMACS_INT, not int, for byte and char and arg counts.
18717 Support field widths and precisions larger than INT_MAX. Avoid
18718 sprintf's undefined behavior with conversion specifications such as %#d
18719 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18720 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18721 formatting out-of-range floating point numbers with int
18722 formats. (Bug#8668)
18724 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18726 * data.c: Avoid integer truncation in expressions involving floats.
18727 * data.c: Include <intprops.h>.
18728 (arith_driver): When there's an integer overflow in an expression
18729 involving floating point, convert the integers to floating point
18730 so that the resulting value does not suffer from catastrophic
18731 integer truncation. For example, on a 64-bit host (* 4
18732 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18733 Do not rely on undefined behavior after integer overflow.
18735 merge count_size_as_multibyte, parse_str_to_multibyte
18736 * character.c, character.h (count_size_as_multibyte):
18737 Rename from parse_str_to_multibyte; all uses changed.
18738 Check for integer overflow.
18739 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18740 since it's now a duplicate of the other. This is more of
18741 a character than a buffer op, so better that it's in character.c.
18742 * fns.c, print.c: Adjust to above changes.
18744 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18746 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18748 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18750 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18751 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18752 (x_clipboard_manager_save): Now static.
18753 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18755 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18756 (crypto_hash_function): Now static.
18757 Fix pointer signedness problems. Avoid unnecessary initializations.
18759 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18761 * termhooks.h (Vselection_alist): Make it terminal-local.
18763 * terminal.c (create_terminal): Initialize it.
18765 * xselect.c: Support for clipboard managers.
18766 (Vselection_alist): Move to termhooks.h as terminal-local var.
18767 (LOCAL_SELECTION): New macro.
18768 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18769 (symbol_to_x_atom): Remove gratuitous arg.
18770 (x_handle_selection_request, lisp_data_to_selection_data)
18771 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18772 (x_own_selection, x_get_local_selection, x_convert_selection):
18773 New arg, specifying work frame. Use terminal-local Vselection_alist.
18774 (some_frame_on_display): Delete unused function.
18775 (Fx_own_selection_internal, Fx_get_selection_internal)
18776 (Fx_disown_selection_internal, Fx_selection_owner_p)
18777 (Fx_selection_exists_p): New optional frame arg.
18778 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18779 (x_handle_selection_clear): Don't treat other terminals with the
18780 same keyboard specially. Use the terminal-local Vselection_alist.
18781 (x_clear_frame_selections): Use Frun_hook_with_args.
18783 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18785 * xterm.h: Add support for those atoms.
18787 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18789 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18790 (converted_selections, conversion_fail_tag): New global variables.
18791 (x_selection_request_lisp_error): Free the above.
18792 (x_get_local_selection): Remove unnecessary code.
18793 (x_reply_selection_request): Args changed; handle arbitrary array
18794 of converted selections stored in converted_selections.
18795 Separate the XChangeProperty and SelectionNotify steps.
18796 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18797 (x_convert_selection): New function.
18798 (x_handle_selection_event): Simplify.
18799 (x_get_foreign_selection): Don't ignore incoming requests while
18800 waiting for an answer; this will fail when we implement
18801 SAVE_TARGETS, and seems unnecessary anyway.
18802 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18803 (Vx_sent_selection_functions): Doc fix.
18805 2011-05-26 Leo Liu <sdl.web@gmail.com>
18807 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18809 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18811 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18813 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18814 for fringe update if it has periodic bitmap.
18815 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18816 and fringe_bitmap_periodic_p.
18818 * fringe.c (get_fringe_bitmap_data): New function.
18819 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18820 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18821 row. Mark glyph row for fringe update if periodicity changed.
18823 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18824 for fringe update unless it has periodic bitmap.
18826 2011-05-25 Kenichi Handa <handa@m17n.org>
18828 * xdisp.c (get_next_display_element): Set correct it->face_id for
18829 a static composition.
18831 2011-05-24 Leo Liu <sdl.web@gmail.com>
18834 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18836 * fns.c (crypto_hash_function, Fsha1): New function.
18837 (Fmd5): Use crypto_hash_function.
18838 (syms_of_fns): Add Ssha1.
18840 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18842 * gnutls.c: Remove unused macros.
18843 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18844 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18845 Remove macros that are defined and never used.
18846 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18848 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18850 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18851 (Fx_get_selection_internal): Minor cleanup.
18852 (Fx_own_selection_internal): Rename arguments for consistency with
18855 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18857 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18859 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18861 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18863 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18865 * dispnew.c (scrolling_window): Don't exclude the case that the
18866 last enabled row in the desired matrix touches the bottom boundary.
18868 2011-05-21 Glenn Morris <rgm@gnu.org>
18870 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18871 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18872 and add some more files.
18874 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18876 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18877 report_file_error introduced by the change from 2011-05-07.
18879 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18881 * systime.h (Time): Define only if emacs is defined.
18882 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18883 where the include path doesn't have X11/X.h by default. See
18884 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18886 2011-05-20 Kenichi Handa <handa@m17n.org>
18888 * composite.c (find_automatic_composition): Fix previous change.
18890 2011-05-20 Glenn Morris <rgm@gnu.org>
18892 * lisp.mk: New file, split from Makefile.in.
18893 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18894 (shortlisp): Remove.
18895 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18897 2011-05-19 Glenn Morris <rgm@gnu.org>
18899 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18900 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18901 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18902 (lisp): Set the order to that of loadup.el.
18903 (shortlisp): Make it a copy of $lisp.
18904 (SOME_MACHINE_LISP): Remove.
18905 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18906 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18908 2011-05-18 Kenichi Handa <handa@m17n.org>
18910 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18911 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18912 (find_automatic_composition): Mostly rewrite for efficiency.
18914 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18916 * makefile.w32-in: Update dependencies.
18918 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18920 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18921 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18923 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18925 Fix some integer overflow issues, such as string length overflow.
18927 * insdel.c (count_size_as_multibyte): Check for string overflow.
18929 * character.c (lisp_string_width): Check for string overflow.
18930 Use EMACS_INT, not int, for string indexes and lengths; in
18931 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18932 the resulting string length overflows an EMACS_INT; instead,
18933 report a string overflow if no precision given. When checking for
18934 precision exhaustion, use a check that cannot possibly have
18935 integer overflow. (Bug#8675)
18936 * character.h (lisp_string_width): Adjust to new signature.
18938 * alloc.c (string_overflow): New function.
18939 (Fmake_string): Use it. This doesn't change behavior, but saves
18940 a few bytes and will simplify future changes.
18941 * character.c (string_escape_byte8): Likewise.
18942 * lisp.h (string_overflow): New decl.
18944 Fixups, following up to the user-interface timestamp change.
18945 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18946 for UI timestamps, instead of unsigned long.
18947 * msdos.c (mouse_get_pos): Likewise.
18948 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18949 * w32gui.h (Time): Define by including "systime.h" rather than by
18950 declaring it ourselves. (Bug#8664)
18952 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18953 * image.c (clear_image_cache): Likewise.
18955 * term.c (term_mouse_position): Don't assume time_t wraparound.
18957 Be more systematic about user-interface timestamps.
18958 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18959 and sometimes 'EMACS_UINT', to represent these timestamps.
18960 This change causes it to use 'Time' uniformly, as that's what X uses.
18961 This makes the code easier to follow, and makes it easier to catch
18962 integer overflow bugs such as Bug#8664.
18963 * frame.c (Fmouse_position, Fmouse_pixel_position):
18964 Use Time, not unsigned long, for user-interface timestamps.
18965 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18966 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18967 * keyboard.h (last_event_timestamp): Likewise.
18968 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18969 * menu.h (xmenu_show): Likewise.
18970 * term.c (term_mouse_position): Likewise.
18971 * termhooks.h (struct input_event.timestamp): Likewise.
18972 (struct terminal.mouse_position_hook): Likewise.
18973 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18974 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18975 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18976 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18977 what it was before.
18978 * menu.h, termhooks.h: Include "systime.h", for Time.
18980 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18981 Don't assume that the difference between two unsigned long values
18982 can fit into an integer. At this point, we know button_down_time
18983 <= event->timestamp, so the difference must be nonnegative, so
18984 there's no need to cast the result if double-click-time is
18985 nonnegative, as it should be; check that it's nonnegative, just in
18986 case. This bug is triggered when events are more than 2**31 ms
18987 apart (about 25 days). (Bug#8664)
18989 * xselect.c (last_event_timestamp): Remove duplicate decl.
18990 (x_own_selection): Remove needless cast to unsigned long.
18992 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18993 that always fit in int. Use a sentinel instead of a counter, to
18994 avoid a temp and to allay GCC's concerns about possible int overflow.
18995 * frame.h (struct frame): Use int for menu_bar_items_used
18996 instead of EMACS_INT, since it always fits in int.
18998 * menu.c (grow_menu_items): Check for int overflow.
19000 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19002 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19003 Before, the code was not consistent. These values cannot exceed
19004 2**31 - 1 so there's no need to make them unsigned.
19005 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19006 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19007 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19009 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19011 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19012 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19013 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19014 presumably because the widths might not match.
19016 * window.c (size_window): Avoid needless test at loop start.
19018 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19020 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19022 2011-05-12 Drew Adams <drew.adams@oracle.com>
19024 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19026 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19028 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19029 `width' to `bar_area_x' and `bar_area_width', respectively.
19030 (x_scroll_run): Take account of fringe background extension.
19032 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19033 Rename local vars `left' and `width' to `bar_area_x' and
19034 `bar_area_width', respectively.
19035 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19036 background extension.
19038 2011-05-10 Jim Meyering <meyering@redhat.com>
19040 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19042 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19044 * image.c (Finit_image_library): Return t for built-in image types,
19045 like pbm and xbm. (Bug#8640)
19047 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19049 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19051 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19053 * w32console.c (Fset_screen_color): Doc fix.
19054 (Fget_screen_color): New function.
19055 (syms_of_ntterm): Defsubr it.
19057 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19058 unlink the temporary file if Fcall_process didn't create it in the
19060 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19061 child process will be redirected to a file specified with `:file'.
19062 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19063 cue to call_process_cleanup not to close that handle.
19065 2011-05-07 Ben Key <bkey76@gmail.com>
19067 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19068 one of two shell specific rules, either bootstrap-temacs-CMD or
19069 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19070 to the previous implementation of the bootstrap-temacs rule.
19071 The bootstrap-temacs-CMD rule is similar to the previous
19072 implementation of the bootstrap-temacs rule except that it
19073 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19076 These changes, along with some changes to nt/configure.bat,
19077 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19078 earlier fix to add support for --cflags and --ldflags options
19079 that include quotes so that it works whether make uses cmd or
19082 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19084 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19085 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19087 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19088 a string. Handle both cases.
19089 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19090 (Fdbus_register_method): Use Qinvalid_function.
19092 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19094 * makefile.w32-in: Update dependencies.
19095 (LISP_H): Add inttypes.h and stdin.h.
19096 (PROCESS_H): Add unistd.h.
19098 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19100 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19101 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19103 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19105 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19107 * term.c (vfatal): Remove stray call to va_end.
19108 It's not needed and the C Standard doesn't allow it here anyway.
19110 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19111 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19113 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19116 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19118 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19120 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19122 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19124 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19126 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19127 * charset.c (Fdefine_charset_internal): Don't initialize
19128 charset.code_space[15]. The value was garbage, on hosts with
19129 32-bit int (Bug#8600).
19131 * lread.c (read_integer): Be more consistent with string-to-number.
19132 Use string_to_number to do the actual conversion; this avoids
19133 rounding errors and fixes some other screwups. Without this fix,
19134 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19135 (digit_to_number): Move earlier, for benefit of read_integer.
19136 Return -1 if the digit is out of range for the base, -2 if it is
19137 not a digit in any supported base. (Bug#8602)
19139 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19141 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19142 to match comment at start of function. This also removes a
19143 GCC warning about overflow in a 32+64-bit port.
19145 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19147 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19148 Reported by Stefan Monnier in
19149 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19150 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19151 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19153 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19154 (EMACS_UINTPTR): Likewise, with uintptr_t.
19156 * lisp.h: Prefer 64-bit EMACS_INT if available.
19157 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19158 on 32-bit hosts that have 64-bit int, so that they can access
19160 However, temporarily disable this change unless the temporary
19161 symbol WIDE_EMACS_INT is defined.
19163 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19165 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19166 This removes an assumption that EMACS_INT and long are the same
19167 width as pointers. The assumption is true for Emacs porting targets
19168 now, but we want to make other targets possible.
19169 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19170 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19171 In the rest of the code, change types of integers that hold casted
19172 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19173 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19174 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19175 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19176 No need to cast type when ORing.
19177 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19178 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19179 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19180 assume EMACS_INT is the same width as char *.
19181 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19182 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19183 Remove no-longer-needed casts.
19184 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19185 (xg_tool_bar_help_callback, xg_make_tool_item):
19186 Use EMACS_INTPTR to hold an integer
19187 that will be cast to void *; this can avoid a GCC warning
19188 if EMACS_INT is not the same width as void *.
19189 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19190 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19191 (current_message_1, set_message_1):
19192 Use a local to convert to proper width without a cast.
19193 * xmenu.c (dialog_selection_callback): Likewise.
19195 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19196 Also, don't assume VALBITS / RAND_BITS is less than 5,
19197 and don't rely on undefined behavior when shifting a 1 left into
19199 * lisp.h (get_random): Change signature to match.
19201 * lread.c (hash_string): Use size_t, not int, for hash computation.
19202 Normally we prefer signed values; but hashing is special, because
19203 it's better to use unsigned division on hash table sizes so that
19204 the remainder is nonnegative. Also, size_t is the natural width
19205 for hashing into memory. The previous code used 'int', which doesn't
19206 retain enough info to hash well into very large tables.
19207 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19209 * dbusbind.c: Don't possibly lose pointer info when converting.
19210 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19211 Use XPNTR rather than XHASH, so that the high-order bits of
19212 the pointer aren't lost when converting through void *.
19214 * eval.c (Fautoload): Don't double-shift a pointer.
19216 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19218 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19220 * gnutls.c (DEF_GNUTLS_FN):
19221 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19223 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19225 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19228 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19230 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19231 New version that can reserve upto 2GB of heap space.
19233 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19235 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19237 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19239 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19240 `gnutls_certificate_set_x509_key_file'.
19242 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19244 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19245 Update dependencies.
19247 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19249 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19250 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19251 Remove unused parameter `fildes'.
19252 * process.c (read_process_output, send_process): Don't pass it.
19254 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19256 Fix previous change: the library cache is defined in w32.c.
19257 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19258 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19260 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19262 Implement dynamic loading of GnuTLS on Windows.
19264 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19265 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19266 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19269 * gnutls.c (Qgnutls_dll): Define.
19270 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19271 (gnutls_*): Declare function pointers.
19272 (init_gnutls_functions): New function to initialize function pointers.

19275 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19276 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19277 (emacs_gnutls_write, emacs_gnutls_read)
19278 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19279 (Fgnutls_available_p): New function.
19280 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

19290 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19292 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19293 (w32_delayed_load): Move from image.c. When loading a library, record
19294 its filename in the :loaded-from property of the library id.
19295 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19296 Initialize and staticpro them.
19297 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19299 * process.c: Include lisp.h before w32.h, not after.
19300 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19301 instead of gnutls_record_check_pending.
19303 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19305 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19307 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19308 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19311 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19313 * xterm.c (x_set_frame_alpha): Do not set property on anything
19314 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19316 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19318 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19320 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19322 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

19336 * sysdep.c (wait_for_termination_1): Make static.
19337 (wait_for_termination, interruptible_wait_for_termination):
19338 Move after wait_for_termination_1.
19340 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19342 * sysdep.c (interruptible_wait_for_termination): New function
19343 which is like wait_for_termination, but allows keyboard
19346 * callproc.c (Fcall_process): Add (:file "file") as an option for
19348 (Fcall_process_region): Ditto.
19350 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19352 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19353 rather than `XVECTOR (FOO)->size'.
19355 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19356 inttypes.h, as a gnulib replacement is used if it not available in
19359 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19361 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19362 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19363 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19365 * coding.c (coding_alloc_by_realloc): Error out if destination
19366 will grow beyond MOST_POSITIVE_FIXNUM.
19367 (decode_coding_emacs_mule): Abort if there isn't enough place in
19368 charbuf for the composition carryover bytes. Reserve an extra
19369 space for up to 2 characters produced in a loop.
19370 (decode_coding_iso_2022): Abort if there isn't enough place in
19371 charbuf for the composition carryover bytes.
19373 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19375 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19376 aborting when %lld or %lll format is passed.
19377 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19378 %llo or %llx format is passed. (Bug#8545)
19380 * window.c (window_scroll_line_based): Use a marker instead of
19381 simple variables to record original value of point. (Bug#7952)
19383 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19384 produced by %s or %c overflows available buffer space. (Bug#8545)
19386 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19388 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19395 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19397 * keyboard.c (Qdelayed_warnings_hook): Define.
19398 (command_loop_1): Run `delayed-warnings-hook'
19399 if Vdelayed_warnings_list is non-nil.
19400 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19401 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19403 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19405 * doprnt.c (doprnt): Don't return value smaller than the buffer
19406 size if the message was truncated. (Bug#8545).
19408 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19410 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19411 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19413 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19415 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19417 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19419 * makefile.w32-in: Update dependencies.
19421 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19423 Improve `doprnt' and its usage. (Bug#8545)
19424 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19425 `format_end'. Remove support for %l as a conversion specifier.
19426 Don't use xrealloc. Improve diagnostics when the %l size modifier
19427 is used. Update the commentary.
19429 * eval.c (verror): Simplify calculation of size_t.
19431 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19434 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19436 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19439 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19441 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19442 This makes this file independent of the recent pseudovector change.
19444 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19446 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19448 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19449 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19450 Remove unused local.
19451 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19453 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19454 GCC 4.6.0 optimizes based on type-based alias analysis.
19455 For example, if b is of type struct buffer * and v of type struct
19456 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19457 != &v->size, and therefore "v->size = 1; b->size = 2; return
19458 v->size;" must therefore return 1. This assumption is incorrect
19459 for Emacs, since it type-puns struct Lisp_Vector * with many other
19460 types. To fix this problem, this patch adds a new type struct
19461 vectorlike_header that documents the constraints on layout of vectors
19462 and pseudovectors, and helps optimizing compilers not get fooled
19463 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19464 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19465 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19467 (XSETPVECTYPE): Rewrite in terms of new macro.
19468 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19469 This is a bit clearer, and further avoids the possibility of
19470 undesirable aliasing.
19471 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19472 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19473 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19474 since Lisp_Subr is a special case (no "next" field).
19475 (ASIZE): Now uses header.size rather than size.
19476 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19477 to avoid the hassle of writing XVECTOR (foo)->header.size.
19478 (struct vectorlike_header): New type.
19479 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19480 object, to help avoid aliasing.
19481 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19482 (SUBRP): Likewise, since Lisp_Subr is a special case.
19483 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19484 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19485 (struct Lisp_Hash_Table): Combine first two members into a single
19486 struct vectorlike_header member. All uses of "size" and "next" members
19487 changed to be "header.size" and "header.next".
19488 * buffer.h (struct buffer): Likewise.
19489 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19490 * frame.h (struct frame): Likewise.
19491 * process.h (struct Lisp_Process): Likewise.
19492 * termhooks.h (struct terminal): Likewise.
19493 * window.c (struct save_window_data, struct saved_window): Likewise.
19494 * window.h (struct window): Likewise.
19495 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19496 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19497 * buffer.c (init_buffer_once): Likewise.
19498 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19500 * process.c (Fformat_network_address): Use local var for size,
19503 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19505 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19506 * data.c (atof): Remove decl; no longer used or needed.
19507 (digit_to_number): Move to lread.c.
19508 (Fstring_to_number): Use new string_to_number function, to be
19509 consistent with how the Lisp reader treats infinities and NaNs.
19510 Do not assume that floating-point numbers represent EMACS_INT
19511 without losing information; this is not true on most 64-bit hosts.
19512 Avoid double-rounding errors, by insisting on integers when
19513 parsing non-base-10 numbers, as the documentation specifies.
19514 * lisp.h (string_to_number): New decl, replacing ...
19515 (isfloat_string): Remove.
19516 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19517 (read1): Do not accept +. and -. as integers; this
19518 appears to have been a coding error. Similarly, do not accept
19519 strings like +-1e0 as floating point numbers. Do not report
19520 overflow for integer overflows unless the base is not 10 which
19521 means we have no simple and reliable way to continue.
19522 Break out the floating-point parsing into a new
19523 function string_to_number, so that Fstring_to_number parses
19524 floating point numbers consistently with the Lisp reader.
19525 (digit_to_number): Move here from data.c. Make it static inline.
19526 (E_CHAR, EXP_INT): Remove, replacing with ...
19527 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19528 (string_to_number): New function, replacing isfloat_string.
19529 This function checks for valid syntax and produces the resulting
19530 Lisp float number too. Rework it so that string-to-number
19531 no longer mishandles examples like "1.0e+". Use strtoumax,
19532 so that overflow for non-base-10 numbers is reported only when
19533 there's no portable and simple way to convert to floating point.
19535 * textprop.c (set_text_properties_1): Rewrite for clarity,
19536 and to avoid GCC warning about integer overflow.
19538 * intervals.h (struct interval): Use EMACS_INT for members
19539 where EMACS_UINT might cause problems. See
19540 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19541 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19542 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19544 (offset_intervals): Tell GCC not to worry about length overflow
19545 when negating a negative length.
19547 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19548 (overrun_check_free): Likewise.
19550 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19551 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19554 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19555 (gnutls_make_error): Rename local to avoid shadowing.
19556 (gnutls_emacs_global_deinit): ifdef out; not used.
19557 (Fgnutls_boot): Use const for pointer to readonly storage.
19558 Comment out unused local. Fix pointer signedness problems.
19560 * lread.c (openp): Don't stuff size_t into an 'int'.
19561 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19562 about possible signed overflow.
19564 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19565 (GDK_KEY_g): Don't define if already defined.
19566 (xg_prepare_tooltip): Avoid pointer signedness problem.
19567 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19569 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19570 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19572 * xfns.c (Fx_window_property): Simplify a bit,
19573 to make a bit faster and to avoid GCC 4.6.0 warning.
19574 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19576 * fns.c (internal_equal): Don't assume size_t fits in int.
19578 * alloc.c (compact_small_strings): Tighten assertion a little.
19580 Replace pEd with more-general pI, and fix some printf arg casts.
19581 * lisp.h (pI): New macro, generalizing old pEd macro to other
19582 conversion specifiers. For example, use "...%"pI"d..." rather
19583 than "...%"pEd"...".
19584 (pEd): Remove. All uses replaced with similar uses of pI.
19585 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19586 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19587 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19588 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.

19590 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19591 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19593 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19594 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19595 * print.c (safe_debug_print, print_object): Likewise.
19596 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19598 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19599 avoiding the 0 flag, which is not portable.
19600 * process.c (Fmake_network_process): Use pI to avoid cast.
19601 * region-cache.c (pp_cache): Likewise.
19602 * xdisp.c (decode_mode_spec): Likewise.
19603 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19604 behavior on 64-bit hosts with printf arg.
19605 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19606 (x_stop_queuing_selection_requests): Likewise.
19607 (x_get_window_property): Don't truncate byte count to an 'int'
19610 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19611 here, since it parses constructs like leading '-' and spaces,
19612 which are not wanted; and it overflows with large numbers.
19613 Instead, simply match F[0-9]+, which is what is wanted anyway.
19615 * alloc.c: Remove unportable assumptions about struct layout.
19616 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19617 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19618 (allocate_vectorlike, make_pure_vector): Use the new macros,
19619 plus offsetof, to remove unportable assumptions about struct layout.
19620 These assumptions hold on all porting targets that I know of, but
19621 they are not guaranteed, they're easy to remove, and removing them
19622 makes further changes easier.
19624 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19625 This doesn't fix a bug but makes the code clearer.
19626 (string_overrun_cookie): Now const. Use initializers that
19627 don't formally overflow signed char, to avoid warnings.
19628 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19629 can cause Emacs to crash when string overrun checking is enabled.
19630 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19631 multiple of sizeof (EMACS_INT); it need not be, if
19632 alignof(EMACS_INT) < sizeof (EMACS_INT).
19633 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19635 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19662 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19664 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19665 "cast to pointer from integer of different size".
19667 Improve doprnt and its use in verror. (Bug#8545)
19668 * doprnt.c (doprnt): Document the set of format control sequences
19669 supported by the function. Use SAFE_ALLOCA instead of always
19672 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19673 is one byte too soon. Don't use xrealloc; instead xfree and
19676 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19678 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

19682 gnutls_global_initialized. Added internals for the
19683 :verify-hostname-error, :verify-error, and :verify-flags
19684 parameters of `gnutls-boot' and documented those parameters in the
19685 docstring. Start callback support.
19686 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19687 unless a fatal error occurred. Call gnutls_alert_send_appropriate

19765 conversions. Support %l conversion. Don't assume an EMACS_INT
19766 argument for integer conversions and for %c.
19768 * lisp.h (doprnt): Restore prototype.
19770 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

19791 codepoint of an invalid character, to avoid displaying a bogus
19794 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19795 `error', not SYMBOL_NAME itself.

19800 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19801 to `error' in error message about FINAL_CHAR argument. Make sure
19802 FINAL_CHAR is a character, and use %c when it is passed as
19803 argument to `error'.
19805 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19807 * s/ms-w32.h (localtime): Redirect to sys_localtime.
19809 * w32.c: Include <time.h>.

19869 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19870 by pacifying GCC about it. Maybe it's time to retire it?
19871 * xfaces.c (USG, __TIMEVAL__): Likewise.
19873 * dispextern.h (struct redisplay_interface): Rename param
19874 to avoid shadowing.
19875 * termhooks.h (struct terminal): Likewise.
19876 * xterm.c (xembed_send_message): Likewise.
19878 * insdel.c (make_gap_smaller): Define only if
19879 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
19881 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
19884 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
19885 so that we aren't warned about unused symbols.

19922 compatible char. Avoid the old compiler warnings about
19923 out-of-range initializers by using, for example, '\xab' rather
19926 * xgselect.c (xgselect_initialize): Check vs interface
19927 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

19977 (group_in_compile_stack, re_search, re_search_2, regex_compile)
19978 (re_compile_pattern, re_exec): Declare arguments and local
19979 variables `size_t' and `ssize_t' and return values `regoff_t', as

19987 specify buffer/string position and length are now ssize_t and
19988 size_t. Return type is regoff_t.
19990 2011-04-16 Ben Key <bkey76@gmail.com>
19992 * nsfont.m: Fixed bugs in ns_get_family and
19993 ns_descriptor_to_entity that were caused by using free to
19994 deallocate memory blocks that were allocated by xmalloc (via
19995 xstrdup). This caused Emacs to crash when compiled with
19996 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19997 --enable-checking=xmallocoverrun). xfree is now used to
19998 deallocate these memory blocks.

20425 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
20426 Mark functions with DEFUE instead of DEFUN,
20427 if they are used in other modules.
20428 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20429 decls for now-static functions.
20430 * buffer.h (Fdelete_overlay): Remove decl.
20431 * callproc.c (Fgetenv_internal): Mark as internal.

20466 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20468 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20469 when at ZV. (Bug#8487)
20471 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20473 * charset.c (Fclear_charset_maps): Use xfree instead of free.
20475 * keyboard.c (parse_tool_bar_item): Likewise.
20476 * sound.c (sound_cleanup, alsa_close): Likewise.
20477 * termcap.c (tgetent): Likewise.
20478 * xfns.c (x_default_font_parameter): Likewise.
20479 * xsettings.c (read_and_apply_settings): Likewise.
20481 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20482 (overrun_check_free): Protoize.
20484 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20486 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20487 since callers should never pass a negative size.
20488 Change the signature to match that of plain 'read' and 'write'; see
20489 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20490 * lisp.h: Update prototypes of emacs_write and emacs_read.
20492 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20494 * xdisp.c (redisplay_window): Don't try to determine the character
20495 position of the scroll margin if the window start point w->startp
20496 is outside the buffer's accessible region. (Bug#8468)
20498 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20500 Fix write-region and its subroutines for buffers > 2GB.
20501 * fileio.c (a_write, e_write): Modify declaration of arguments and
20502 local variables to support buffers larger than 2GB.
20503 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20505 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20506 argument, local variables, and return value.
20508 * lisp.h: Update prototypes of emacs_write and emacs_read.
20510 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20512 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20514 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20516 Fix more problems found by GCC 4.6.0's static checks.
20518 * xdisp.c (vmessage): Use a better test for character truncation.
20520 * charset.c (load_charset_map): <, not <=, for optimization,
20521 and to avoid potential problems with integer overflow.
20522 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20523 * casetab.c (set_identity, shuffle): Likewise.
20524 * editfns.c (Fformat): Likewise.
20525 * syntax.c (skip_chars): Likewise.
20527 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20528 This also lets GCC 4.6.0 generate slightly better loop code.
20530 * callint.c (Fcall_interactively): <, not <=, for optimization.
20531 (Fcall_interactively): Count the number of arguments produced,
20532 not the number of arguments given. This is simpler and lets GCC
20533 4.6.0 generate slightly better code.
20535 * ftfont.c: Distingish more carefully between FcChar8 and char.
20536 The previous code passed unsigned char * to a functions like
20537 strlen and xstrcasecmp that expect char *, which does not
20538 conform to the C standard.
20539 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20540 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20541 char * when the C standard requires it.
20543 * keyboard.c (read_char): Remove unused var.
20545 * eval.c: Port to Windows vsnprintf (Bug#8435).
20546 Include <limits.h>.
20547 (SIZE_MAX): Define if the headers do not.
20548 (verror): Do not give up if vsnprintf returns a negative count.
20549 Instead, grow the buffer. This ports to Windows vsnprintf, which
20550 does not conform to C99. Problem reported by Eli Zaretskii.
20551 Also, simplify the allocation scheme, by avoiding the need for
20552 calling realloc, and removing the ALLOCATED variable.
20554 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20556 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20557 But keep the doprint source code for now, as we might revamp it
20558 and use it again (Bug#8435).
20559 * lisp.h (doprnt): Remove.
20560 * Makefile.in (base_obj): Remove doprnt.o.
20561 * deps.mk (doprnt.o): Remove.
20563 error: Print 32- and 64-bit integers portably (Bug#8435).
20564 Without this change, on typical 64-bit hosts error ("...%d...", N)
20565 was used to print both 32- and 64-bit integers N, which relied on
20566 undefined behavior.
20567 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20568 * lisp.h (error, verror): Mark as printf-like functions.
20569 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20570 Report overflow in size calculations when allocating printf buffer.
20571 Do not truncate output string at its first null byte.
20572 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20573 Truncate the output at a character boundary, since vsnprintf does not
20575 * charset.c (check_iso_charset_parameter): Convert internal
20576 character to string before calling 'error', since %c now has the
20578 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20579 overflow when computing char to be passed to 'error'. Do not
20580 pass Lisp_Object to 'error'; pass the integer instead.
20581 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20582 formatted with plain %d.
20584 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20586 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20588 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20590 * xterm.c (x_catch_errors): Remove duplicate declaration.
20592 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20594 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20596 2011-04-10 Jim Meyering <meyering@redhat.com>
20598 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20599 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20600 return ssize_t not "int", and use size_t as the buffer length.
20601 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20602 * gnutls.h: Update declarations.
20603 * process.c (read_process_output): Use ssize_t, to match.
20604 (send_process): Likewise.
20606 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20608 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20610 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20612 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20613 Use unsigned char, to match FcChar8 type definition.
20615 * xterm.c (handle_one_xevent):
20616 * xmenu.c (create_and_show_popup_menu):
20617 * xselect.c (x_decline_selection_request)
20618 (x_reply_selection_request): Avoid type-punned deref of X events.
20620 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20622 Fix some uses of `int' instead of EMACS_INT.
20623 * search.c (string_match_1, fast_string_match)
20624 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20625 (scan_buffer, find_next_newline_no_quit)
20626 (find_before_next_newline, search_command, Freplace_match)
20627 (Fmatch_data): Make some `int' variables be EMACS_INT.
20629 * xdisp.c (display_count_lines): 3rd argument and return value now
20630 EMACS_INT. All callers changed.
20631 (pint2hrstr): Last argument is now EMACS_INT.
20633 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20634 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20635 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

20646 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20647 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20649 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20650 (encode_invocation_designation): Last argument P_NCHARS is now
20652 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20653 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20655 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20658 * ccl.c (Fccl_execute_on_string): Declare some variables
20661 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20663 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20665 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20667 * process.c (Fformat_network_address): Doc fix.
20669 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20671 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20673 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20675 * keyboard.c (read_char): Call Lisp function help-form-show,
20676 instead of using internal_with_output_to_temp_buffer.
20677 (Qhelp_form_show): New var.
20678 (syms_of_keyboard): Use DEFSYM macro.
20680 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20682 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20684 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20686 * process.c (Flist_processes): Remove to Lisp.
20687 (list_processes_1): Delete.
20689 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20691 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20693 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20695 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20697 Fix more problems found by GCC 4.6.0's static checks.
20699 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20701 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20703 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20705 * xdisp.c (vmessage): Mark as a printf-like function.
20707 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20709 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20711 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20712 printf-like functions.
20713 (tiff_load): Add casts to remove these marks before passing them
20714 to system-supplied API.
20716 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20718 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20719 This avoids several warnings with gcc -Wstrict-overflow.
20720 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20721 directly, rather than having caller test rule sign. This avoids
20722 some unnecessary tests.
20723 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20724 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20725 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20727 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20728 (xfont_open): Avoid unnecessary tests.
20730 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20732 * composite.h, composite.c (composition_gstring_put_cache):
20733 Use EMACS_INT, not int, for length.

20736 breaking out part of COMPOSITION_DECODE_RULE.
20737 (COMPOSITION_DECODE_RULE): Use it.

20739 by using the new macro.
20741 * textprop.c (set_text_properties_1): Change while to do-while,
20742 since the condition is always true at first.
20744 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20745 (interval_deletion_adjustment): Return unsigned value.
20748 * process.c (list_processes_1, create_pty, read_process_output):

20758 (update_syntax_table): Use unsigned instead of int.
20760 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20761 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20762 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20764 * print.c (print_error_message): Avoid int overflow.
20766 * font.c (font_list_entities): Redo for clarity,
20767 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20769 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20770 (font_score): Avoid potential overflow in diff calculation.
20772 * fns.c (substring_both): Remove var that is set but not used.
20773 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20775 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20777 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20778 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20779 can always succeed if overflow has undefined behavior.
20781 * search.c (boyer_moore, wordify): Remove vars set but not used.
20782 (wordify): Omit three unnecessary tests.
20784 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20785 All callers changed. This avoids the need for an unused var.
20787 * casefiddle.c (casify_region): Remove var that is set but not used.
20789 * dired.c (file_name_completion): Remove var that is set but not used.
20791 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20793 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20794 (Finsert_file_contents): Remove unnecessary code checking fd.
20796 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20797 Check for integer overflow on size calculations.
20799 * buffer.c (Fprevious_overlay_change): Remove var that is set
20802 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20803 Remove vars that are set but not used.
20804 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20805 (timer_check_2): Mark vars as initialized.
20807 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20809 * image.c (lookup_image): Remove var that is set but not used.
20810 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20812 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20813 that are set but not used.
20815 * xfns.c (make_invisible_cursor): Don't return garbage
20816 if XCreateBitmapFromData fails (Bug#8410).
20818 * xselect.c (x_get_local_selection, x_handle_property_notify):
20819 Remove vars that are set but not used.
20821 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20822 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20824 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20825 Remove var that is set but not used.
20826 (scroll_bar_windows_size): Now size_t, not int.
20827 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20828 Check for overflow.
20830 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20831 (map_tty_color) [!defined MSDOS]: Likewise.
20833 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20835 * coding.c: Remove vars that are set but not used.
20836 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20837 All callers changed.
20838 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20839 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20840 (decode_coding_charset): Remove vars that are set but not used.
20842 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20843 that is set but not used.
20845 * print.c (print_object): Remove var that is set but not used.
20847 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20848 The gnulib version avoids calling malloc in the usual case,
20849 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20850 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20851 * filelock.c (current_lock_owner): Likewise.
20852 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20853 * sysdep.c: Include allocator.h, careadlinkat.h.
20854 (emacs_no_realloc_allocator): New static constant.
20855 (emacs_readlink): New function.
20856 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20857 ../lib/careadlinkat.h.
20859 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20861 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

20871 * xdisp.c (display_count_lines): Remove parameter `start',
20872 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

20878 (get_per_char_metric): Remove parameter `f', unused since
20879 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20881 2011-04-02 Jim Meyering <meyering@redhat.com>
20883 do not dereference NULL upon failed strdup
20884 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20885 (ns_get_family): Likewise.
20887 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20889 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20891 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20893 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20896 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20898 Add lexical binding.
20900 * window.c (Ftemp_output_buffer_show): New fun.
20901 (Fsave_window_excursion):
20902 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20904 * lread.c (lisp_file_lexically_bound_p): New function.
20905 (Fload): Bind Qlexical_binding.
20906 (readevalloop): Remove `evalfun' arg.
20907 Bind Qinternal_interpreter_environment.
20908 (Feval_buffer): Bind Qlexical_binding.
20909 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20911 (syms_of_lread): Declare `lexical-binding'.
20913 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20915 * keyboard.c (eval_dyn): New fun.
20916 (menu_item_eval_property): Use it.
20918 * image.c (parse_image_spec): Use Ffunctionp.
20920 * fns.c (concat, mapcar1): Accept byte-code-functions.
20922 * eval.c (Fsetq): Handle lexical vars.
20923 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20924 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20925 (FletX, Flet): Obey lexical binding.
20926 (Fcommandp): Handle closures.
20927 (Feval): New `lexical' arg.
20928 (eval_sub): New function extracted from Feval. Use it almost
20929 everywhere where Feval was used. Look up vars in lexical env.
20931 (Ffunctionp): Move from subr.el.
20932 (Ffuncall): Handle closures.
20933 (apply_lambda): Remove `eval_flags'.
20934 (funcall_lambda): Handle closures and new byte-code-functions.
20935 (Fspecial_variable_p): New function.
20936 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20937 but without exporting it to Lisp.
20939 * doc.c (Fdocumentation, store_function_docstring):
20940 * data.c (Finteractive_form): Handle closures.
20942 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20945 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20947 (exec_byte_code): New function extracted from Fbyte_code to handle new
20948 calling convention for byte-code-functions. Add new byte-codes.
20950 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20952 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20954 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20956 * xdisp.c (redisplay_internal): Fix prototype.
20958 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20960 * xdisp.c (SCROLL_LIMIT): New macro.
20961 (try_scrolling): Use it when setting scroll_limit.
20962 Limit scrolling to 100 screen lines.
20963 (redisplay_window): Even when falling back on "recentering",
20964 position point in the window according to scroll-conservatively,
20965 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20967 (try_scrolling): When point is above the window, allow searching
20968 as far as scroll_max, or one screenful, to compute vertical
20969 distance from PT to the scroll margin position. This prevents
20970 try_scrolling from unnecessarily failing when
20971 scroll-conservatively is set to a value slightly larger than the
20972 window height. Clean up the case of PT below the margin at bottom
20973 of window: scroll_max can no longer be INT_MAX. When aggressive
20974 scrolling is in use, don't let point enter the opposite scroll
20975 margin as result of the scroll.
20976 (syms_of_xdisp) <scroll-conservatively>: Document the
20977 threshold of 100 lines for never-recentering scrolling.
20979 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20981 * dispextern.h (move_it_by_lines):
20982 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20983 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20984 (message_log_check_duplicate): Remove parameters `prev_bol' and
20985 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20986 (redisplay_internal): Remove parameter `preserve_echo_area',
20987 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20989 * indent.c (Fvertical_motion):
20990 * window.c (window_scroll_pixel_based, Frecenter):
20991 Don't pass `need_y_p' to `move_it_by_lines'.
20993 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20995 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20996 steal a few bits to be more compact.
20997 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20998 Remove unneeded casts.
21000 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21002 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21004 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21005 binding" message (bug#7967).
21007 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21009 Fix more problems found by GCC 4.6.0's static checks.
21011 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21012 Remove unused local var.
21014 * editfns.c (Fmessage_box): Remove unused local var.
21016 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21017 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21018 Omit unused local vars.
21019 * window.c (shrink_windows): Omit unused local var.
21020 * menu.c (digest_single_submenu): Omit unused local var.
21021 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21022 Omit unused local var.
21024 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21025 Don't assume string length fits in int.
21026 (keyremap_step, read_key_sequence): Use size_t for sizes.
21027 (read_key_sequence): Don't check last_real_key_start redundantly.
21029 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21030 instead of alloca (Bug#8344).
21032 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21033 (Fbacktrace_frame): Don't assume nframes fits in int.
21035 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

21040 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21042 * cm.c (calccost): Turn while-do into do-while, for clarity.
21044 * keyboard.c (syms_of_keyboard): Use the same style as later
21045 in this function when indexing through an array. This also
21046 works around GCC bug 48267.
21048 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21050 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21052 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21053 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21055 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21056 This avoids undefined behavior on integer overflow, and is a bit
21057 more convenient anyway since it is compared to a size_t variable.
21059 Variadic C functions now count arguments with size_t, not int.
21060 This avoids an unnecessary limitation on 64-bit machines, which
21061 caused (substring ...) to crash on large vectors (Bug#8344).

21071 * fns.c (concat): Likewise.
21072 * frame.c (x_set_frame_parameters): Likewise.
21073 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21074 0 if not found, not -1. All callers changed.
21076 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21077 (stack_copy_size): Now size_t, not int.
21078 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

21099 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21100 don't set the hook to nil, but remove the offending function instead.
21101 (Qcommand_hook_internal): Remove, unused.
21102 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21103 Vcommand_hook_internal.
21105 * eval.c (enum run_hooks_condition): Remove.
21106 (funcall_nil, funcall_not): New functions.
21107 (run_hook_with_args): Call each function through a `funcall' argument.

21284 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21286 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21287 unconditionally since it does the check itself.
21289 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21291 Fix more problems found by GCC 4.5.2's static checks.
21293 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21294 the first time through the loop, since we know p0 < p1 then.
21295 This also avoids a gcc -Wstrict-overflow warning.
21297 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21298 leading to a memory leak, possible in functions like
21299 load_charset_map_from_file that can allocate an unbounded number
21300 of objects (Bug#8318).
21302 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21303 that could (at least in theory) be that large.
21305 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21306 This is less likely to overflow, and avoids undefined behavior if
21307 overflow does occur. All callers changed. Use strtoul to scan
21308 for the unsigned long integer.
21309 (pint2hrstr): Simplify and tune code slightly.
21310 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21312 * scroll.c (do_scrolling): Work around GCC bug 48228.
21313 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

21320 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21323 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21325 * process.c (Fmake_network_process): Use socklen_t, not int,
21326 where POSIX says socklen_t is required in portable programs.
21327 This fixes a porting bug on hosts like 64-bit HP-UX, where
21328 socklen_t is wider than int (Bug#8277).
21329 (Fmake_network_process, server_accept_connection):
21330 (wait_reading_process_output, read_process_output):
21333 * process.c: Rename or move locals to avoid shadowing.

21343 Make tparam.h and terminfo.c consistent.
21344 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21345 Include tparam.h instead, since it declares them.
21346 * cm.h (PC): Remove extern decl; tparam.h now does this.
21347 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21348 * terminfo.c: Include tparam.h, to check interfaces.
21349 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21350 (tparam): Adjust signature to match interface in tparam.h;
21351 this removes some undefined behavior. Check that outstring and len
21352 are zero, which they always are with Emacs.
21353 * tparam.h (PC, BC, UP): New extern decls.
21355 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21356 (xftfont_open): Rename locals to avoid shadowing.

21374 (composition_update_it): Mark var as initialized.
21375 (find_automatic_composition): Mark vars as initialized,
21376 with a FIXME (Bug#8290).

21382 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21383 to avoid shadowing.
21385 * textprop.c (property_change_between_p): Remove; unused.
21387 * intervals.c (interval_start_pos): Now static.
21389 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21395 Fix pointer signedness.
21396 (alsa_choose_format): Remove unused local var.
21397 (wav_play): Initialize a variable to 0, to prevent undefined
21398 behavior (Bug#8278).
21400 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21402 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21404 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21405 clobbering (Bug#8298).
21406 * sysdep.c (sys_subshell): Likewise.
21407 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21409 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21410 This should get cleaned up, so that child_setup has the
21411 same signature on all platforms.
21413 * callproc.c (call_process_cleanup): Now static.
21414 (relocate_fd): Rename locals to avoid shadowing.
21416 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21418 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21419 not to be necessary, and produces flickering.
21421 2011-03-20 Glenn Morris <rgm@gnu.org>
21423 * config.in: Remove file.
21425 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21427 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21428 are now in src/globals.h.
21429 (syms_of_minibuf): Remove spurious & from previous change.

21439 * xfaces.c (Fx_load_color_file):
21440 Read color file from absolute filename (bug#8250).
21442 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
21444 * makefile.w32-in: Update dependencies.
21446 2011-03-17 Eli Zaretskii <eliz@gnu.org>
21448 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

21455 (sigchld_handler): Now static.
21457 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
21458 That way, the code declares only the vars that it needs.

21469 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
21470 Define only if needed.
21472 * unexelf.c (unexec): Name an expression,
21473 to avoid gcc -Wbad-function-cast warning.
21474 Use a different way to cause a compilation error if anyone uses
21475 n rather than nn, a way that does not involve shadowing.
21476 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21478 * deps.mk (unexalpha.o): Remove; unused.
21480 New file unexec.h, the (simple) interface for unexec (Bug#8267).
21481 * unexec.h: New file.
21482 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
21483 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
21484 Depend on unexec.h.
21485 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
21486 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
21487 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
21488 Change as necessary to match prototype in unexec.h.
21490 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

21543 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
21544 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21545 some of which prompt warnings from gcc -Wbad-function-cast.
21546 (Fformat_time_string, Fencode_time, Finsert_char):
21547 (Ftranslate_region_internal, Fformat):
21548 Rename or remove local vars to avoid shadowing.

21551 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
21554 * lisp.h (eassert): Check that the argument compiles, even if
21555 ENABLE_CHECKING is not defined.
21557 * data.c (Findirect_variable): Name an expression, to avoid
21558 gcc -Wbad-function-cast warning.

21570 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
21571 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
21573 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
21574 (GC_STRING_CHARS): Remove; not used.
21575 (Fmemory_limit): Cast sbrk's returned value to char *.
21577 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21578 avoids undefined behavior in theory.
21580 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21582 Use functions, not macros, for up- and down-casing (Bug#8254).
21583 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21584 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21585 to use the following functions instead of these macros.
21586 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21587 EMACS_INT, since callers assume the returned value fits in int.
21588 (upcase1): Likewise, for UPCASE_TABLE.
21589 (uppercasep, lowercasep, upcase): New static inline functions.
21590 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21599 which gcc can warn about.
21600 (regex_compile, re_match_2_internal): Mark locals as initialized.
21601 (RETALLOC_IF): Define only if needed.
21602 (WORDCHAR_P): Likewise. This one is never needed, but is used
21603 only in a comment talking about a compiler bug, so put inside
21604 the #if 0 of that comment.
21605 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21606 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21609 * search.c (boyer_moore): Rename locals to avoid shadowing.

21632 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21633 New macros, so that the caller can use some names other than
21634 gcpro1, gcpro2, etc.
21635 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21637 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21638 argument, for consistency with GCPRO2_VAR, etc: it is now the
21639 prefix of the variable, not the variable itself. All uses
21641 * dired.c (directory_files_internal, file_name_completion):
21642 Rename locals to avoid shadowing.
21644 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21645 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21646 dired.c's scmp function, had undefined behavior.
21647 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21648 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21649 * buffer.h: ... to here, because these macros use current_buffer,
21650 and the new implementation with inline functions needs to have
21651 current_buffer in scope now, rather than later when the macros
21653 (downcase, upcase1): New static inline functions.
21654 (DOWNCASE, UPCASE1): Reimplement using these functions.
21655 This avoids undefined behavior in expressions like
21656 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21657 from race conditions in accessing the global variables
21658 case_temp1 and case_temp2.
21659 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21660 * lisp.h (case_temp1, case_temp2): Remove their decls.
21661 * character.h (ASCII_CHAR_P): Move from here ...
21662 * lisp.h: ... to here, so that the inline functions mentioned
21663 above can use them.
21665 * dired.c (directory_files_internal_unwind): Now static.
21667 * fileio.c (file_name_as_directory, directory_file_name):

21670 (file_name_as_directory): Use const pointers when appropriate.
21671 (Fexpand_file_name): Likewise. In particular, newdir might
21672 point at constant storage, so make it a const pointer.
21673 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21674 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21676 (Fset_file_times, Finsert_file_contents, auto_save_error):
21677 Rename locals to avoid shadowing.
21679 * minibuf.c (choose_minibuf_frame_1): Now static.

21681 to avoid shadowing.
21683 * marker.c (bytepos_to_charpos): Remove; unused.
21685 * lisp.h (verify_bytepos, count_markers): New decls,
21686 so that gcc does not warn that these functions aren't declared.
21688 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21689 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21690 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21691 (copy_text): Remove unused local var.
21693 * filelock.c (within_one_second): Now static.
21694 (lock_file_1): Rename local to avoid shadowing.
21696 * buffer.c (fix_overlays_before): Mark locals as initialized.
21697 (fix_start_end_in_overlays): Likewise. This function should be
21698 simplified by using pointers-to-pointers, but that's a different
21700 (switch_to_buffer_1): Now static.
21701 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21702 (report_overlay_modification): Rename locals to avoid shadowing.
21704 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21705 Fix pointer signedness issue.
21706 (sys_subshell): Mark local as volatile if checking for lint,
21707 to suppress a gcc -Wclobbered warning that does not seem to be right.
21708 (MAXPATHLEN): Define only if needed.
21710 * process.c (serial_open, serial_configure): Move decls from here ...
21711 * systty.h: ... to here, so that they can be checked.
21713 * fns.c (get_random, seed_random): Move extern decls from here ...
21714 * lisp.h: ... to here, so that they can be checked.
21716 * sysdep.c (reset_io): Now static.
21717 (wait_for_termination_signal): Remove; unused.
21719 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21722 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21723 (DENSE_TABLE_SIZE): Remove; unused.
21724 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21725 (describe_map_tree):
21726 Rename locals to avoid shadowing.
21728 * keyboard.c: Declare functions static if they are not used elsewhere.
21729 (echo_char, echo_dash, cmd_error, top_level_2):
21730 (poll_for_input, handle_async_input): Now static.

21734 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
21735 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
21736 (read_key_sequence, read_char): Mark locals as initialized.

21743 * lisp.h (force_auto_save_soon): New decl.
21745 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
21746 (DEFINE_DUMMY_FUNCTION): New macro.
21747 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
21749 (main): Add casts to avoid warnings
21750 if GCC considers string literals to be constants.
