12 (command_loop_2, top_level_1): Add static to match prototype.
14 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
16 Fix a recently-introduced delete-process race condition.
17 * callproc.c, process.h (record_kill_process):
18 New function, containing part of the old call_process_kill.
19 (call_process_kill): Use it.
20 This does not change call_process_kill's behavior.
21 * process.c (Fdelete_process): Use record_kill_process to fix a
22 race condition that could cause Emacs to lose track of a child.
24 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
26 Avoid code duplication between prev_frame and next_frame.
27 * frame.c (candidate_frame): New function. Add comment.
28 (prev_frame, next_frame): Use it. Adjust comment.
30 2012-12-06 Eli Zaretskii <eliz@gnu.org>
32 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
33 fails, signal an error instead of continuing with an empty
35 Encode expanded temp file pattern before passing it to mkstemp or
38 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
39 Encode the file name before passing it to dostounix_filename, in
40 case it will downcase it (under w32-downcase-file-names).
43 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
45 Minor call-process cleanups.
46 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
47 at the same time as other platforms, to simplify analysis.
48 No need for fd0_volatile since we have synch_process_fd.
49 Avoid needless emacs_close; arg is always negative.
51 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
53 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
56 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
58 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
59 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
60 and mouse_face_hidden members to a bitfields.
61 * frame.h (struct frame): Remove set-but-not-used space_width member.
62 (FRAME_SPACE_WIDTH): Remove.
63 * nsterm.m, w32term.c, xterm.c: Adjust users.

69 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
71 Don't let call-process be a zombie factory (Bug#12980).
72 Fixing this bug required some cleanup of the signal-handling code.
73 As a side effect, this change also fixes a longstanding rare race
74 condition whereby Emacs could mistakenly kill unrelated processes,
75 and it fixes a bug where a second C-g does not kill a recalcitrant
76 synchronous process in GNU/Linux and similar platforms.
77 The patch should also fix the last vestiges of Bug#9488,
78 a bug which has mostly been fixed on the trunk by other changes.
79 * callproc.c, process.h (synch_process_alive, synch_process_death)
80 (synch_process_termsig, sync_process_retcode):
81 Remove. All uses removed, to simplify analysis and so that
82 less consing is done inside critical sections.
83 * callproc.c (call_process_exited): Remove. All uses replaced
84 with !synch_process_pid.
85 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
86 These take the role of what used to be in unwind-protect arg.
88 (block_child_signal, unblock_child_signal):
89 New functions, to avoid races that could kill innocent-victim processes.
90 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
91 (call_process_kill): Record killed processes as deleted, so that
92 zombies do not clutter up the system. Do this inside a critical
93 section, to avoid a race that would allow the clutter.
94 (call_process_cleanup): Fix code so that the second C-g works again
95 on common platforms such as GNU/Linux.
96 (Fcall_process): Create the child process in a critical section,
97 to fix a race condition. If creating an asynchronous process,
98 record it as deleted so that zombies do not clutter up the system.
99 Do unwind-protect for WINDOWSNT too, as that's simpler in the
100 light of these changes. Omit unnecessary call to emacs_close
101 before failure, as the unwind-protect code does that.
102 * callproc.c (call_process_cleanup):
103 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
104 * process.c (record_deleted_pid): New function, containing
105 code refactored out of Fdelete_process.
106 (Fdelete_process): Use it.
107 (process_status_retrieved): Remove. All callers changed to use
109 (record_child_status_change): Remove, folding its contents into ...
110 (handle_child_signal): ... this signal handler. Now, this
111 function is purely a handler for SIGCHLD, and is not called after
112 a synchronous waitpid returns; the synchronous code is moved to
113 wait_for_termination. There is no need to worry about reaping
114 more than one child now.
115 * sysdep.c (get_child_status, child_status_changed): New functions.
116 (wait_for_termination): Now takes int * status and bool
117 interruptible arguments, too. Do not record child status change;
118 that's now the caller's responsibility. All callers changed.
119 Reimplement in terms of get_child_status.
120 (wait_for_termination_1, interruptible_wait_for_termination):
121 Remove. All callers changed to use wait_for_termination.
122 * syswait.h: Include <stdbool.h>, for bool.
123 (record_child_status_change, interruptible_wait_for_termination):
125 (record_deleted_pid, child_status_changed): New decls.
126 (wait_for_termination): Adjust to API changes noted above.
128 * bytecode.c, lisp.h (Qbytecode): Remove.
129 No longer needed after 2012-11-20 interactive-p changes.
131 2012-12-03 Eli Zaretskii <eliz@gnu.org>
133 * xdisp.c (redisplay_window): If the cursor is visible, but inside
134 the scroll margin, move point outside the margin. (Bug#13055)
136 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
138 * gtkutil.c (my_log_handler): New function.

143 * lisp.h (modify_region): Rename to...
144 (modify_region_1): ...new prototype.
145 * textprop.c (modify_region): Now static. Adjust users.
146 * insdel.c (modify_region): Rename to...
147 (modify_region_1): ...new function to work with current buffer.
148 Adjust comment and users. Use true and false for booleans.
150 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
152 * alloc.c (free_save_value): New function.
153 (safe_alloca_unwind): Use it.
154 * lisp.h (free_save_value): New prototype.
155 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
157 (save_excursion_restore): Adjust to match saved data structure.
158 Use free_save_value to offload some work from GC. Drop obsolete
161 2012-12-03 Chong Yidong <cyd@gnu.org>
163 * fileio.c (Vauto_save_list_file_name): Doc fix.
165 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
167 * w32fns.c: Remove prototype of atof.
168 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
170 (file_dialog_callback): Declared UINT_PTR.
172 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
175 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
176 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
179 2012-12-03 Glenn Morris <rgm@gnu.org>
181 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
183 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
185 Fix xpalloc confusion after memory is exhausted.
186 * alloc.c (xpalloc): Comment fix.
187 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
188 and signals an error, do not clear charset_table_size, as
189 charset_table is still valid.
190 * doprnt.c (evxprintf): Clear *BUF after freeing it.
192 Use execve to avoid need to munge environ (Bug#13054).
193 * callproc.c (Fcall_process):
194 * process.c (create_process):
195 Don't save and restore environ; no longer needed.
196 * callproc.c (child_setup):
197 Use execve, not execvp, to preserve environ.
199 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
201 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
203 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
205 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
206 display for sliced images (Bug#10500).

213 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
215 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
217 * xdisp.c (window_outdated): Remove eassert since it hits
218 some suspicious corner cases (see Bug#13007 and Bug#13012).
219 (mode_line_update_needed): New function.
220 (redisplay_internal, redisplay_window): Use it.

230 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
232 * callproc.c (Fcall_process): Fix vfork portability problems.
233 Do not assume that fd[0], count, filefd, and save_environ survive
234 vfork. Fix bug whereby wrong errno value could be reported for
235 pipe failure. Some minor cleanups, too, as follows. Move buf and
236 bufsize to the context where they're needed. Change new_argv to
237 be of type char **, as this is more convenient and avoids casts.
238 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
239 Now local constants, not macros.
241 2012-11-18 Kenichi Handa <handa@gnu.org>
243 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
244 for the variable "f".

291 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
292 between bpos_covered and bpos_max. This fixes cursor display when
293 several display strings follow each other.
295 * .gdbinit (pgx): If the glyph's object is a string, display the
296 pointer to string data, rather than the value of the string object
297 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
299 * indent.c (Fvertical_motion): If the starting position is covered
300 by a display string, return to one position before that, to avoid
301 overshooting it inside move_it_to. (Bug#12930)

331 _D_EXACT_NAMELEN if available, as it's faster than strlen.
332 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
333 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
334 * makefile.w32-in (DIR_H): Remove. All uses replaced with

400 Define for the MSVC compiler.
402 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
404 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
405 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
406 dostounix_filename. Prevents crashes down the road, because
407 dostounix_filename assumes it gets a unibyte string. Reported by
408 Michel de Ruiter <michel@sentient.nl>, see

487 ($(BLD)/sysdep.$(O)): Update dependencies.
489 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
491 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
492 * callproc.c (relocate_fd): Assume F_DUPFD.
493 * emacs.c, term.c (O_RDWR): Remove.
494 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
495 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
496 * nsterm.m: Assume <fcntl.h> exists.
497 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
498 (create_pty, Fmake_network_process, server_accept_connection)
499 (wait_reading_process_output, init_process_emacs):
501 (wait_reading_process_output): Put in a special case for WINDOWSNT
502 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
503 It's not clear this is needed, but it's a more-conservative change.
504 (create_process): Assume FD_CLOEXEC.
505 (create_process, create_pty): Assume O_NOCTTY.
506 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
507 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
508 Omit if not DOS_NT, since F_GETFL is not defined there.
509 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
510 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
512 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
513 lack it, since gnulib guarantees this.
514 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
516 2012-11-17 Eli Zaretskii <eliz@gnu.org>
518 * w32.c (faccessat): Pretend that directories have the execute bit
519 set. Emacs expects that, e.g., in files.el:cd-absolute.
521 * w32proc.c (create_child): Don't clip the PID of the child
522 process to fit into an Emacs integer, as this is no longer a
524 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
525 reaping only the process specified by PID argument, if that is
526 positive. Use PID instead of dead_child to know which process to
527 reap. Wait for the child to die only if WNOHANG is not in
529 (sys_select): Don't set dead_child.
531 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
532 as it is no longer needed.
534 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
536 (record_child_status_change): Remove the setting of
537 record_at_most_one_child for the !WNOHANG case.
539 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
541 Fix problems in ns port found by static checking.
542 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
543 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
544 not to process group.
545 (ns_select): Use emacs_write, not write, as that's more robust
546 in the presence of signals.
547 (fd_handler:): Check for read errors.
549 2012-11-16 Glenn Morris <rgm@gnu.org>
551 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
553 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
555 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
557 2012-11-16 Eli Zaretskii <eliz@gnu.org>
559 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
560 use the same value of thread handle.
561 (start_timer_thread): If the timer thread exited (due to error),
562 clean up by closing the two handles it used. Duplicate the caller
563 thread's handle here, so it gets duplicated only once, when
564 launching the timer thread. Set priority of the timer thread, not
566 (getitimer): Don't duplicate the caller thread's handle here.
569 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
571 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
574 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
576 Remove no-longer-used pty_max_bytes variable.
577 * process.c (pty_max_bytes): Remove; unused.
578 (send_process): Do not set it.
580 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
582 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
585 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
587 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
588 This follows up on the 2012-09-29 patch that removed indirection
589 for the 'function' field. Reported by Sergey Vinokurov in
590 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
592 2012-11-14 Eli Zaretskii <eliz@gnu.org>
594 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
595 different name, as the MS runtime does not have such a function,
596 and probably never will.) All callers changed. Ignore DIRFD
597 value if PATH is an absolute file name, to match Posix spec
598 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
601 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
603 * xdisp.c (echo_area_display, redisplay_internal):
604 Omit redundant check whether frame_garbaged is set.
606 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
608 Use faccessat, not access, when checking file permissions (Bug#12632).
609 This fixes a bug that has been present in Emacs since its creation.
610 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
611 which must set some sort of record. (Torek's bug report was against
612 a predecessor of GNU Emacs, but GNU Emacs happened to have the
613 same common flaw.) See Torek's Usenet posting
614 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
615 Posted: Fri Apr 8 14:18:56 1983.
616 * Makefile.in (LIB_EACCESS): New macro.
618 * callproc.c (init_callproc):
619 * charset.c (init_charset):
620 * fileio.c (check_existing, check_executable, check_writable)
622 * lread.c (openp, load_path_check):
623 * process.c (allocate_pty):
625 Use effective UID when checking permissions, not real UID.
626 * callproc.c (init_callproc):
627 * charset.c (init_charset):
628 * lread.c (load_path_check, init_lread):
629 Test whether directories are accessible, not merely whether they exist.
630 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
631 * fileio.c (check_existing, check_executable, check_writable)
633 Use symbolic names instead of integers for the flags, as they're
635 (check_writable): New arg AMODE. All uses changed.
636 Set errno on failure.
637 (Ffile_readable_p): Use faccessat, not stat + open + close.
638 (Ffile_writable_p): No need to call check_existing + check_writable.
639 Just call check_writable and then look at errno. This saves a syscall.
640 dir should never be nil; replace an unnecessary runtime check
641 with an eassert. When checking the parent directory of a nonexistent
642 file, check that the directory is searchable as well as writable, as
643 we can't create files in unsearchable directories.
644 (file_directory_p): New function, which uses 'stat' on most platforms
645 but faccessat with D_OK (for efficiency) if WINDOWSNT.
646 (Ffile_directory_p, Fset_file_times): Use it.
647 (file_accessible_directory_p): New function, which uses a single
648 syscall for efficiency.
649 (Ffile_accessible_directory_p): Use it.
650 * xrdb.c (file_p): Use file_directory_p.
651 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
652 * lread.c (openp): When opening a file, use fstat rather than
653 stat, as that avoids a permissions race. When not opening a file,
654 use file_directory_p rather than stat.
655 (dir_warning): First arg is now a usage string, not a format.
656 Use errno. All uses changed.
657 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
658 that merely introduced a race.
659 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
660 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
661 and similarly for the other O_* flags.
662 * w32.c (sys_faccessat): Rename from sys_access and switch to
663 faccessat's API. All uses changed.
664 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
665 (magic_db): Rename from magic_file_p.
666 (magic_db, search_magic_path): Return an XrmDatabase rather than a
667 char *, so that we don't have to test for file existence
668 separately from opening the file for reading. This removes a race
669 fixes a permission-checking problem, and simplifies the code.
671 (file_p): Remove; no longer needed.
673 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
675 Omit glyphs initialization at startup.
676 * dispnew.c (glyphs_initialized_initially_p): Remove.
677 (adjust_frame_glyphs_initially): Likewise. Adjust users.
678 (Fredraw_frame): Move actual code from here...
679 (redraw_frame): ...to here. Add eassert. Adjust comment.
680 (Fredraw_display): Use redraw_frame.
681 * xdisp.c (clear_garbaged_frames): Likewise.
683 2012-11-13 Eli Zaretskii <eliz@gnu.org>
685 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
686 passed to pint2str and pint2hrstr to be at most the size of the
687 frame's decode_mode_spec_buffer. This avoids crashes with very
688 large values of FIELD_WIDTH argument to decode_mode_spec.
691 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
693 Fix a race with verify-visited-file-modtime (Bug#12863).
694 Since at least 1991 Emacs has ignored an mtime difference of no
695 more than one second, but my guess is that this was to work around
696 file system bugs that were fixed long ago. Since the race is
697 causing problems now, let's remove that code.
698 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
699 whose time stamp is off by no more than a second. Insist that the
700 file time stamps match exactly.
702 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
704 * frame.h (struct frame): Convert external_tool_bar member to
705 1-bit unsigned bitfield.
706 * termhooks.h (struct terminal): Remove mouse_moved member since
707 all users are long dead. Adjust comment on mouse_position_hook.
709 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
711 Simplify by using FOR_EACH_FRAME here and there.
712 * frame.c (next_frame, prev_frame, other_visible_frames)
713 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
714 * w32term.c (x_window_to_scroll_bar): Likewise.
715 * window.c (window_list): Likewise.
716 * xdisp.c (x_consider_frame_title): Likewise.
717 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
718 * xfns.c (x_window_to_frame, x_any_window_to_frame)
719 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
720 * xmenu.c (menubar_id_to_frame): Likewise.
721 * xselect.c (frame_for_x_selection): Likewise.
722 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
723 (x_window_to_menu_bar): Likewise.
724 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
726 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
728 * data.c (Qdefalias_fset_function): Now static.
730 Another tweak to vectorlike_header change.
731 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
732 Remove, and replace all uses with ...
733 (next_in_free_list, set_next_in_free_list):
734 New functions, which respect C's aliasing rules better.
736 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
738 * window.c (list4i): Rename from 'quad'. All uses changed.
739 Needed because <sys/types.h> defines 'quad' on Solaris 10.
741 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
743 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
744 warning about mixing declarations and code in ISO C90.
746 2012-11-10 Martin Rudalics <rudalics@gmx.at>
748 * window.c (Fsplit_window_internal): Set combination limit of
749 new parent window to t iff Vwindow_combination_limit is t;
750 fixing a regression introduced with the change from 2012-09-22.
751 (Fset_window_combination_limit): Fix doc-string.
753 2012-11-10 Eli Zaretskii <eliz@gnu.org>
755 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
756 amount when the scroll margins are too large. When scrolling
757 backwards in the buffer, give up if cannot reach point or the
758 scroll margin within a reasonable number of screen lines.
759 Fixes point position in window under scroll-up/down-aggressively when
760 point is positioned many lines beyond the window top/bottom.
763 * ralloc.c (relinquish): If real_morecore fails to return memory
764 to the system, don't crash; instead, leave the last heap
765 unchanged and return. (Bug#12774)
767 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
769 * lisp.h (AUTOLOADP): New macro.
770 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
771 * data.c (Ffset): Remove special ad-advice-info handling.
772 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
774 (Finteractive_form): Simplify.
775 (Fquo): Don't insist on having at least 2 arguments.
776 (Qdefalias_fset_function): New var.
778 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
780 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
782 * nsfont.m (Qcondensed, Qexpanded): New variables.
783 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
784 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
786 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
788 Fix recently introduced crash on MS-Windows (Bug#12839).
789 * w32term.h (struct scroll_bar): Use convenient header.
790 (SCROLL_BAR_VEC_SIZE): Remove.
791 * w32term.c (x_scroll_bar_create): Use VECSIZE.
793 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
795 Tweak last vectorlike_header change.
796 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
797 vectorlike object on the free list. This is introduced to avoid
798 some (but not all) pointer casting and aliasing problems, see
799 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
800 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
802 (xvectype, xvecsize): Use them to examine Lisp_Object values.
804 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
806 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
807 been removed, so remove them here also.
809 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
811 * doc.c (Fdocumentation): Handle new property
812 dynamic-docstring-function to replace the old ad-advice-info.
814 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
816 * fns.c (Qeql, hashtest_eq): Now static.
818 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
820 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
821 * fns.c (hashfn_eq, hashfn_eql, sxhash):
822 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
823 * buffer.c (compare_overlays): Use XLI rather than XHASH.
825 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
827 Use same hash function for hashfn_profiler as for hash_string etc.
828 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
829 * lisp.h (sxhash_combine): New inline function, with the contents
830 of the old SXHASH_COMBINE.
831 * profiler.c (hashfn_profiler): Use it, instead of having a
832 special hash function containing a comparison that always yields 1.
834 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
836 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
837 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
838 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
841 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
843 * image.c (xpm_make_color_table_h): Fix compiler error because
844 make_hash_table changed.
846 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
848 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
850 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
852 Use ad-hoc comparison function for the profiler's hash-tables.
853 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
854 (make_log): Use them.
855 (handle_profiler_signal): Don't inhibit quit any longer since we don't
856 call Fequal any more.

863 * fns.c (make_hash_table): Take a struct to describe the test.
864 (cmpfn_eql, cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
865 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
866 (hash_lookup, hash_remove_from_table): Move assertion checking of
867 hashfn result here. Check hash-equality before calling cmpfn.

869 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
870 (syms_of_fns): Initialize them.

879 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
880 value of w32-scroll-lock-modifier is neither nil nor one of the
881 known key modifiers. (Bug#12806)
883 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
885 Shrink struct vectorlike_header to the only size field.
886 * lisp.h (enum pvec_type): Avoid explicit enum member values.
888 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
889 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
890 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
891 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
892 information from the vector header. Adjust comment.

902 (enum mem_type): Adjust comment.
903 (NEXT_IN_FREE_LIST): New macro.
904 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
905 (Fmake_bool_vector): Likewise.
906 (struct large_vector): New type to represent allocation unit for
907 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
908 (large_vectors): Change type to struct large_vector.
909 (allocate_vector_from_block): Simplify.
910 (PSEUDOVECTOR_NBYTES): Replace with...
911 (vector_nbytes): ...new function. Adjust users.
912 (sweep_vectors): Adjust processing of large vectors.
913 (allocate_vectorlike): Likewise.
914 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
915 Add easserts. Adjust XSETPVECTYPESIZE usage.
916 (allocate_buffer): Use BUFFER_PVEC_INIT.
917 (live_vector_p): Adjust to match large vector.
918 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
919 * buffer.h (struct buffer): Add next member.
920 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
922 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
923 * fns.c (internal_equal): Adjust to match enum pvec_type change.

928 (xvecsize): New command.
930 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
932 * keyboard.c (event_to_kboard): Do not dereference
933 frame_or_window field of SELECTION_REQUEST_EVENT
934 and SELECTION_CLEAR_EVENT events (Bug#12814).
935 * xterm.h (struct selection_input_event): Adjust comment.
937 2012-11-07 Eli Zaretskii <eliz@gnu.org>
939 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
940 such as Scroll Lock, if the respective keys are treated as
941 function keys, not as modifiers. This avoids destroying non-ASCII
942 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
944 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
946 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
948 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
950 Restore some duplicate definitions (Bug#12814).
951 This undoes part of the 2012-11-03 changes. Some people build
952 with plain -g rather than with -g3, and they need the duplicate
953 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
954 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
955 Define as macros, as well as as enums or as constants.
957 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
959 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
960 to keypad keys (Bug#12816).
962 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
964 Minor adjustments of recently-changed frame functions.
965 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
966 known to be a frame (we're in the FRAMEP branch).
967 * lisp.h (Qframep): Remove decl. frame.h declares this.
968 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
969 since they're meant for Lisp fixnum values.
971 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
973 * window.c (Fwindow_combination_limit): Revert to the only
974 required argument and adjust docstring as suggested in
975 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
976 by Martin Rudalics <rudalics@gmx.at>.
978 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
980 Widely used frame validity and checking functions.
981 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
982 * frame.c (decode_live_frame, decode_any_frame): New functions.
983 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
984 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
985 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

993 * lisp.h (frame_buffer_predicate): Remove prototype.
994 * buffer.c (Fother_buffer): Use decode_any_frame.
995 * xdisp.c (Ftool_bar_lines_needed): Likewise.
996 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
997 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
998 (Fclose_font, Ffont_info): Use decode_live_frame.
999 * fontset.c (check_fontset_name): Likewise.
1000 * terminal.c (Fframe_terminal): Likewise.
1001 * w32fns.c (check_x_frame): Likewise.
1002 * window.c (Fminibuffer_window, Fwindow_at)
1003 (Fcurrent_window_configuration): Likewise.

1007 * xfaces.c (frame_or_selected_frame): Remove.
1008 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1009 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1010 (Fframe_face_alist): Use decode_live_frame.
1011 * xfns.c (check_x_frame): Likewise.
1013 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

1018 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1019 (Fwindow_line_height): Use it.
1020 (Fwindow_fringes): Use list3.
1021 (Fwindow_scroll_bars): Use list4.
1022 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1023 (Fwindow_combination_limit): Allow zero number of arguments.
1025 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1027 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1029 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1030 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1031 file descriptor 2 for standard error. (Bug#12805)
1033 2012-11-05 Chong Yidong <cyd@gnu.org>
1035 * process.c (wait_reading_process_output): Revert previous change.
1037 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1039 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1040 This removes code that has been obsolete since around 1990.
1041 * callproc.c (Fcall_process):
1043 * process.c (create_process):
1044 * term.c (dissociate_if_controlling_tty):
1045 Assume setsid exists.
1046 * callproc.c (child_setup): Assume setpgid exists and behaves as
1047 per POSIX.1-1988 or later.
1048 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1049 * emacs.c (shut_down_emacs):
1050 * sysdep.c (sys_suspend, init_foreground_group):
1051 Assume getpgrp behaves as per POSIX.1-1998 or later.
1052 * msdos.c (setpgrp): Remove.
1053 (tcgetpgrp, setpgid, setsid): New functions.
1054 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1055 * term.c (no_controlling_tty): Remove; unused.
1056 * w32proc.c (setpgrp): Remove.
1057 (setsid, tcgetpgrp): New functions.
1059 Simplify by assuming __fpending.
1060 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1061 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1062 Do not assume that __fpending's result fits in int.
1064 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1066 Remove EMACS_OUTQSIZE+sleep hack.
1067 * dispnew.c (update_frame_1): Remove hack for terminals slower
1068 than 2400 bps, which throttled Emacs by having it sleep.
1069 This code hasn't worked since at least 2007, when the multi-tty stuff
1070 was added, and anyway those old terminals are long dead.
1071 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1072 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1074 Fix data-loss with --version (Bug#9574).
1075 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1076 as we can't assume that emacs_strerror is initialized, and strerror
1077 is good enough here.
1078 (main): Invoke atexit earlier, to catch earlier instances of
1079 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1081 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1083 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1084 (keyDown): Remap keypad keys to X11 virtual key codes.
1086 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1088 Fix data-loss with --batch (Bug#9574).
1089 * emacs.c: Include <close-stream.h>.
1090 (close_output_streams): New function.
1091 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1092 and handles errors appropriately.
1093 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1096 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1097 The symptom is a diagnostic "GLib-WARNING **: In call to
1098 g_spawn_sync(), exit status of a child process was requested but
1099 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1100 waitpid(), so exit status can't be returned." The diagnostic
1101 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1102 The real bug is a race condition between Emacs and glib: Emacs
1103 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1104 so that glib can't find it. Work around the bug by invoking
1105 waitpid only on subprocesses that Emacs itself creates.
1106 * process.c (create_process, record_child_status_change):
1107 Don't use special value -1 in pid field, as the caller now must
1108 know the pid rather than having the callee infer it.
1109 The inference was sometimes incorrect anyway, due to another race.
1110 (create_process): Set new 'alive' member if child is created.
1111 (process_status_retrieved): New function.
1112 (record_child_status_change): Use it.
1113 Accept negative 1st argument, which means to wait for the
1114 processes that Emacs already knows about. Move special-case code
1115 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1116 processes that have already been waited for, by testing and
1117 clearing new 'alive' member.
1118 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1119 now does this internally.
1120 (handle_child_signal): Let record_child_status_change do all
1121 the work, since we do not want to reap all exited child processes,
1122 only the child processes that Emacs itself created.
1123 * process.h (Lisp_Process): New boolean member 'alive'.
1125 Omit duplicate definitions no longer needed with gcc -g3.
1126 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1127 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1128 Define only as macros. There's no longer any need to also define
1129 these symbols as enums or as constants, since we now assume
1130 gcc -g3 when debugging.
1132 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1134 * lisp.mk: Adjust comments to the fact that term/internal is now
1135 loaded from loadup.el.
1137 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1138 (msdos_fatal_signal): New function.
1139 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1142 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1143 for GCC versions before 4.
1144 (emacs_raise): Define to call msdos_fatal_signal.
1146 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1147 iterator when starting in the middle of a display or overlay
1150 2012-11-03 Chong Yidong <cyd@gnu.org>
1152 * process.c (wait_reading_process_output): Clean up the last
1155 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1157 * process.c (wait_reading_process_output): Avoid a race condition
1158 with SIGIO delivery (Bug#11536).
1160 2012-11-03 Chong Yidong <cyd@gnu.org>
1162 * buffer.c (cursor_type): Untabify docstring.
1164 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1166 * frame.h (struct frame): Drop can_have_scroll_bars member
1167 which is meaningless for a long time. Adjust comments.
1168 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1169 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1171 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1173 * window.c (decode_next_window_args): Update window arg after
1174 calling decode_live_window and so fix crash reported at
1175 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1176 by Juanma Barranquero <lekktu@gmail.com>.
1177 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1178 * font.c (Ffont_at): Likewise.
1180 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1182 * widget.c (resize_cb): New function.
1183 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1184 (EmacsFrameResize): Check if all is up to date before changing frame
1187 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1189 Implement backtrace output for fatal errors on MS-Windows.
1190 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1191 (BACKTRACE_LIMIT_MAX): New macro.
1192 (w32_backtrace): New function.
1193 (emacs_abort): Use w32_backtrace when the user chooses not to
1194 attach a debugger. Update the text of the abort dialog.
1196 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1198 Window-related stuff cleanup here and there.
1199 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1200 Use decode_any_window.
1201 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1202 * xdisp.c (Fformat_mode_line): Likewise.
1203 * font.c (Ffont_at): Use decode_live_window.
1204 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1205 * window.c (decode_next_window_args): Likewise.
1206 (decode_any_window): Remove static.
1207 * window.h (decode_any_window): Add prototype.
1208 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1209 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1212 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1214 Remove pad from struct input_event.
1215 * termhooks.h (struct input_event): Remove padding field.
1217 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1218 member is never cons for a long time. Adjust comment.
1219 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1220 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1221 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1222 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1224 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1226 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1228 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1230 Fix crash when using Emacs as commit editor for git (Bug#12697).
1231 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1232 and it is configured in conf_post.h.
1233 (Fcall_process): Don't invoke both setsid and setpgid; the former
1234 is enough, if it exists.
1235 * callproc.c (Fcall_process, child_setup):
1236 * process.c (create_process): Use setpgid.
1237 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1239 * dispnew.c (init_display): Initialize the foreground group
1240 if we are running a tty display.
1241 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1242 * lisp.h (init_foreground_group): New decl.
1243 * sysdep.c (inherited_pgroup): New static var.
1244 (init_foreground_group, tcsetpgrp_without_stopping)
1245 (narrow_foreground_group, widen_foreground_group): New functions.
1246 (init_sys_modes): Narrow foreground group.
1247 (reset_sys_modes): Widen foreground group.
1249 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1251 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1253 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1255 * minibuf.c (read_minibuf): Restore current buffer since
1256 choose_minibuf_frame calling Fset_frame_selected_window may
1257 change it (Bug#12766).
1259 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1261 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1263 2012-10-30 Kenichi Handa <handa@gnu.org>
1265 * font.c (Ffont_at): If WINDOW is specified and it is not
1266 displaying the current buffer, signal an error.
1268 2012-10-29 Daniel Colascione <dancol@dancol.org>
1270 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1271 In preparation for fixing bug#12739, move these functions from
1274 * coding.h, coding.c: ... to here, and compile them only when
1275 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1276 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1278 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1280 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1281 (timer_loop, getitimer, setitimer): Use it instead of
1282 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1284 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1287 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1289 * nsterm.m (NO_APPDEFINED_DATA): New define.
1290 (last_appdefined_event_data): New variable
1291 (last_appdefined_event): Remove.
1292 (ns_select): Initialize t from last_appdefined_event_data instead
1293 of [last_appdefined_event data1].
1294 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1295 remove last_appdefined_event (Bug#12698).
1297 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1299 * frame.c (x_set_font): Catch internal error.
1301 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1303 Avoid overflow in w32 implementation of interval timers.
1304 When possible, for ITIMER_PROF count only times the main thread
1306 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1307 'volatile ULONGLONG' types. All the other data which was
1308 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1309 (GetThreadTimes_Proc): New typedef.
1310 (w32_get_timer_time): New function, returns a suitable time value
1312 (timer_loop): Enter critical section when accessing ULONGLONG
1313 values of the itimer_data struct, as these accesses are no longer
1314 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1315 Remove unused variable.
1316 (init_timers): Initialize s_pfn_Get_Thread_Times.
1317 (start_timer_thread): Don't assign itimer->caller_thread here.
1318 (getitimer): Assign itimer->caller_thread here.
1319 (setitimer): Always call getitimer to get the value of ticks_now.
1320 (sys_spawnve): Avoid compiler warning about format mismatch.
1322 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1324 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1325 mouse movement events if the menu bar is active. This avoids
1326 producing a busy "hour-glass" cursor by Windows if the mouse
1327 pointer is positioned over a tooltip shown for some menu item.
1329 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1331 Don't assume process IDs fit in int.
1332 * emacs.c (shut_down_emacs) [!DOS_NT]:
1333 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1334 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1335 Use pid_t, not int, to store process IDs, as 'int'
1336 is not wide enough on a few platforms (e.g., AIX and IRIX).
1338 2012-10-23 Kenichi Handa <handa@gnu.org>
1340 The following change is to make face-font-rescale-alist work
1341 correctly for non-ASCII fonts.
1343 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1344 (font_open_for_lface): Handle Vface_font_rescale_alist.
1346 2012-10-23 Chong Yidong <cyd@gnu.org>
1348 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1350 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1352 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1354 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1356 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1359 2012-10-21 Glenn Morris <rgm@gnu.org>
1361 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1363 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1365 Port to OpenBSD 5.1.
1366 * frame.c (Fmouse_position, Fmouse_pixel_position):
1367 * xdisp.c (produce_stretch_glyph):
1368 Declare local vars only when they're needed.
1369 This is clearer and avoids a warning on OpenBSD about unused vars.
1370 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1371 This is safer, and avoids OpenBSD warnings about unused vars.
1372 * keyboard.c (record_menu_key): Remove unnecessary decl.
1373 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1374 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1375 as our definition clashes with OpenBSD's.
1376 * xfaces.c (load_face_colors, check_lface_attrs)
1377 (get_lface_attributes_no_remap, get_lface_attributes)
1378 (lface_fully_specified_p, x_supports_face_attributes_p)
1379 (tty_supports_face_attributes_p, face_fontset, realize_face)
1380 (realize_x_face, realize_tty_face):
1381 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1382 merely Lisp_Object *. This is more informative and avoids
1383 a warning on OpenBSD about accessing beyond an object's size.
1385 2012-10-20 Chong Yidong <cyd@gnu.org>
1387 * lread.c (Fload): Doc fix (Bug#12592).
1389 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1391 * font.c (Ffont_at): Fix previous change.
1393 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1395 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.

1878 GUI facilities in a forked child. Also call syms_of_cygw32,
1879 syms_of_w32select in correct places.
1881 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1882 needs fork-then-exec for daemon launching.
1884 * font.h: Include frame.h.
1886 * image.c: Use the image library cache machinery only when we're
1887 compiling for native WINDOWSNT; Cygwin can use shared libraries
1888 like any other Unixlike system.
1890 * keyboard.c: Clarify a comment regarding the input loop.
1892 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1893 functions directly instead of trying to detect at runtime that our
1894 host operating system supports them. We make this change for two
1895 reasons: Cygwin lacks support for the multibyte character
1896 conversion functions used by the legacy menu code, and Cygwin
1897 never needs to rely on non-Unicode APIs.
1899 * unexw32.c (hinst): Declare extern.
1901 * w32.c: Change header order;
1902 (w32_strerror): Move to w32fns.c because we need it for
1903 non-WINDOWSNT builds.
1905 * w32.h: Add #error macro to make sure we don't include w32.h for
1906 Cygwin builds. Remove w32select declarations.
1908 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1909 w32fns.c. w32console.c is WINDOWSNT-only.
1911 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1912 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1914 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1915 (w32_major_version, w32_minor_version, w32_build_number)
1916 (os_subtype, sound_type): Define here
1917 (w32_defined_color): Make color parameter const for consistency
1918 with other _defined_color functions.
1919 (w32_createwindow): Unconditionally call w32_init_class instead of
1920 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1921 through the code is complex and unnecessary because class
1922 registration is practically free.
1923 (w32_name_of_message): New EMACSDEBUG-only function.
1924 (Fset_message_beep): Move here
1925 (Fx_open_connection): Require that the display name for Windows be
1926 "w32" for consistency, emacsclient disambiguation, and maybe, one
1927 day, multi-window-system support.
1928 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1929 Cygwin files for W32 GUI facilities, since these clearly don't
1930 expect Cygwin names.
1931 (_DebPrint): Define.
1932 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1933 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1934 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1935 (w32_last_error): Remove.
1937 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1939 * w32heap.c (syspage_mask): Declare here.
1940 (cache_system_info): Remove.
1942 * w32inevt.c (faked_key): Define globally, not statically.
1943 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1944 (w32_console_toggle_lock_key): Move to w32fns.c.
1946 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1948 * w32proc.c (_DebPrint): Move to w32fns.c.
1949 * w32select.c: Include string.h, stdio.h for Cygwin.
1950 * w32select.h: New File.
1952 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1954 (w32_message_fd): New variable. Under Cygwin, holds the file
1955 descriptor the system used to tell us about pending thread
1958 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1959 that prevented compilation under non-WINDOWSNT systems.
1961 (w32_initialize): Open /dev/windows and assign it to
1962 w32_message_fd. Provide w32 feature.
1964 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1965 (WM_EMACS_INPUT_READY): add.
1966 (prepend_msg, w32_message_fd): Declare globally.
1969 (keyboard_handle): Use only when WINDOWSNT.
1970 (notify_msg_ready): New function. Posts a message to the main
1971 thread's message queue under CYGWIN, which wakes up the main
1972 thread from select(2) by making the /dev/windows file descriptor
1973 ready. Under WINDOWSNT, it sets an event the same way the old
1976 (post, prepend_msg): Actually call notify_msg_ready instead of
1977 setting the input event directly.
1979 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1981 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1982 but it still has blocs in it, don't return it to the system,
1983 instead of aborting. (Bug#12402)
1985 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1987 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
1989 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
1990 MAC_OS_X_VERSION_10_6.
1991 (syms_of_nsterm): Remove comment about Panther and above for
1993 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
1994 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
1995 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
1997 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
1998 MAC_OS_X_VERSION_10_4.
2000 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2001 MAC_OS_X_VERSION_10_2.
2003 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2005 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2006 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2008 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2009 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2010 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2011 Remove ns_in_resize check.
2012 (ns_clear_frame_area): Remove resize handle code.
2014 * nsfns.m (ns_in_resize): Remove.
2015 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2016 Remove ns_in_resize check.
2018 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2020 Improve sys_siglist detection.
2021 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2022 defined as a macro, as is done in Solaris.
2023 (sys_siglist_entries): New macro.
2024 (save_strsignal): Use it.
2025 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2026 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2028 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2030 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2031 fullscreen/Fullscreen.
2033 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2034 tobar_height is new.
2036 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2037 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2038 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2039 (windowDidResize:): Check for correct window if old style fullscreen.
2040 Capitalize word in comment. Remove incorrect comment.
2041 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2042 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2043 error in drawing background.
2044 (toggleFullScreen:): Remove comment. Rearrange calls.
2045 Set toolbar values to zero, save old height in tobar_height.
2046 Restore tool bar height when leaving fullscreen.
2047 (canBecomeMainWindow): New function.
2049 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2051 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2053 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2055 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2057 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2058 that time stamps of directories could also be changed.
2059 Don't request the too broad GENERIC_WRITE, only the more restrictive
2060 FILE_WRITE_ATTRIBUTES access rights.
2062 * fileio.c (Fset_file_times): Special-case ignoring errors for
2063 directories only on MSDOS, not on MS-Windows.
2065 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2067 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2069 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2071 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2072 see whether CreateFile failed.
2074 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2076 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2077 to avoid similar races.
2078 * keyboard.c (pending_signals): Now bool, not int.
2080 Port timers to OpenBSD, plus check for timer failures.
2081 OpenBSD problem reported by Han Boetes.
2082 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2084 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2085 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2086 like OpenBSD, which has timer_settime but does not declare it.
2087 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2088 whether to use itimerspec-related primitives. All uses of
2089 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2091 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2093 * profiler.c (handle_profiler_signal): Fix a malloc race
2094 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2096 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2098 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2100 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2102 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2103 consistent with the change in return value of 'safe_strsignal'.
2105 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2107 Prefer plain 'static' to 'static inline' (Bug#12541).
2108 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2109 (bidi_set_sor_type, bidi_push_embedding_level)
2110 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2111 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

2115 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2116 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2117 Now 'static', not 'static inline'.
2119 Count overruns when profiling; change units to ns.
2120 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2121 Give extra weight to samples after overruns, to attempt to count
2122 the time more accurately.
2123 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2124 the underlying primitives nominally do ns.
2125 (Fprofiler_cpu_start): Document the change. Mention that
2126 the sampling intervals are only approximate.
2128 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2130 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2132 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2133 case for the special 0 coding-system.
2135 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2136 (Fmake_overlay): Remove redundant tests.
2137 (fix_start_end_in_overlays): Remove redundant recentering.
2139 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2141 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2142 Update dependencies.
2144 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2146 Fix a malloc race condition involving strsignal.
2147 A signal can arrive in the middle of a malloc, and Emacs's signal
2148 handler can invoke strsignal, which can invoke malloc, which is
2149 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2150 Fix it by altering the signal handler so that it does not invoke
2152 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2153 * process.c (status_message): Use const pointer, in case strsignal
2154 is #defined to safe_strsignal.
2155 * sysdep.c (sys_siglist, init_signals): Always define and
2156 initialize a substitute sys_siglist if the system does not define
2157 one, even if HAVE_STRSIGNAL.
2158 (safe_strsignal): Rename from strsignal. Always define,
2159 using sys_siglist. Return a const pointer.
2160 * syssignal.h (safe_strsignal): New decl.
2161 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2163 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2165 * w32proc.c (timer_loop): Fix code that waits for timer
2166 expiration, to avoid high CPU usage.
2168 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2170 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2171 (sweep_weak_table): Remove redundant prototypes.
2173 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2175 * emacs.c: Move the inclusion of TERM_HEADER after including
2176 windows.h on WINDOWSNT. This avoids compilation problems with
2179 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2181 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2182 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2183 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2184 as the previous version used 'void *'.
2186 * ralloc.c (ROUNDUP): Fix last change.
2187 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2190 * w32proc.c <disable_itimers>: New static flag.
2191 (init_timers): Initialize it to zero, after creating the critical
2192 sections used by the timer threads.
2193 (term_timers): Set to 1 before deleting the critical sections.
2194 (getitimer, setitimer): If disable_itimers is non-zero, return an
2195 error indication without doing anything. Reported by Fabrice
2196 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2197 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2199 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2202 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2203 term_ntproc after all the other bookkeeping, to get timers working
2204 as long as possible.
2206 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2208 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2209 Suggested by Juri Linkov in
2210 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2212 Prefer plain 'static' to 'static inline' (Bug#12541).
2213 With static functions, modern compilers inline pretty well by
2214 themselves; advice from programmers often hurts as much as it helps.
2215 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2216 this change shrinks the text size of the Emacs executable by 1.1%
2217 without affecting CPU significantly in my benchmark.
2218 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2293 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
2294 Now 'static', not 'static inline'.
2297 (bidi_copy_it): Do the whole copy with a single memcpy.
2298 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2300 Revert the FOLLOW-SYMLINKS change for file-attributes.
2301 Doing it right would require several changes to Tramp, and there's
2302 not enough time to get that tested before the freeze today.
2303 * dired.c (directory_files_internal, Ffile_attributes):
2306 * frame.c (x_report_frame_params): Port better to wider ints.
2307 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2308 or that pointers can be printed in 15 decimal digits.
2309 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
2311 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>
2313 Support x64 build on MS-Windows.
2314 * w32term.h (SCROLL_BAR_PACK, SCROLL_BAR_UNPACK): Define for x64.

2511 (handle_profiler_signal): Rename from sigprof_handler_1,
2512 for consistency with other handlers. Do not check whether
2513 cpu_log is a hash-table if garbage collecting, since it

2516 for consistency with other handlers.
2517 (setup_cpu_timer): New function, with much of what used to be in

2519 Prefer timer_settime if available, and prefer
2520 thread cputime clocks, then process cputime clocks, then
2521 monotonic clocks, to the old realtime clock. Use make_timeval
2522 to round more-correctly when falling back to setitimer.
2523 (Fprofiler_cpu_start): Use it.
2524 (Fprofiler_cpu_stop): Prefer timer_settime if available.

2772 * gtkutil.c (xg_change_toolbar_position):
2775 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2777 * makefile.w32-in (BLOCKINPUT_H): Remove.

2794 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2796 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2797 fatal_error_backtrace.
2799 * w32proc.c (sys_kill): Undo last change: don't do anything when
2800 invoked to deliver SIGABRT to our own process. This is now
2801 handled by emacs_raise.
2803 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2805 * w32term.c (w32_read_socket): Remove leftover reference to
2806 interrupt_input_pending.
2808 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2810 Do not use SA_NODEFER.
2811 Problem reported by Dani Moncayo in
2812 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2814 * sysdep.c (emacs_abort): Do not reset signal handler.
2815 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2816 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2817 wanted even on POSIXish hosts, and it doesn't work on Windows.
2819 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2821 * xterm.c (x_term_init): Call fixup_locale before and after calling
2822 gtk_init (Bug#12392).
2824 2012-09-23 Chong Yidong <cyd@gnu.org>
2826 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2827 Vdynamic_library_alist.
2829 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2830 (Fgnutls_available_p): Caller changed.
2832 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2833 (Flibxml_parse_xml_region): Likewise.
2835 * dispextern.h (struct image_type): Remove arg from init function.
2837 * image.c (Finit_image_library, lookup_image_type)
2838 (define_image_type): Remove now-unneeded second arg.
2839 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2840 (init_tiff_functions, init_gif_functions, init_svg_functions):
2841 Arglist and w32_delayed_load calling convention changed.
2842 (gs_type): Remove init_gs_functions; there is no such function.
2843 (valid_image_p, make_image): Fix caller to lookup_image_type.
2845 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2847 Simplify and avoid signal-handling races (Bug#12471).
2849 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2850 Avoid recursive loop if there's a fatal error in the function itself.
2851 * atimer.c (pending_atimers):
2852 * blockinput.h: Don't include "atimer.h"; no longer needed.
2853 (interrupt_input_pending): Remove. All uses removed.
2854 pending_signals now counts both atimers and ordinary interrupts.
2855 This is less racy than having three separate pending-signal flags.
2856 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2858 Rename from their upper-case counterparts BLOCK_INPUT,
2859 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2860 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2861 This makes it easier to access volatile variables more accurately.
2862 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2863 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2864 that's more reliable if the code is buggy and sets
2865 interrupt_input_blocked to a negative value. All uses changed.
2866 * atimer.c (deliver_alarm_signal):
2867 Remove. No need to deliver this to the parent; any thread can
2868 handle this signal now. All uses replaced by underlying handler.
2869 * atimer.c (turn_on_atimers):
2870 * dispnew.c (handle_window_change_signal):
2871 * emacs.c (handle_danger_signal):
2872 * keyboard.c (kbd_buffer_get_event):
2873 Don't reestablish signal handler; not needed with sigaction.
2874 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2876 Rework to avoid unnecessary accesses to volatile variables.
2877 (UNBLOCK_INPUT_TO): Now a function.
2878 (totally_unblock_input, unblock_input): New decls.
2879 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2880 (init_data): Remove. Necessary stuff now done in init_signal.
2881 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2882 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2883 (fatal_error_code): Remove; no longer needed.
2884 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2885 it doesn't always backtrace. All uses changed. No need to reset
2886 signal to default, since sigaction and/or die does that for us now.
2887 Use emacs_raise (FOO), not kill (getpid (), FOO).
2888 (main): Check more-accurately whether we're dumping.
2889 Move fatal-error setup to sysdep.c
2890 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2891 * gtkutil.c (xg_get_file_name, xg_get_font):
2892 Remove no-longer-needed signal-mask manipulation.
2893 * keyboard.c, process.c (POLL_FOR_INPUT):
2894 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2895 * keyboard.c (read_avail_input): Remove.
2896 All uses replaced by gobble_input.
2897 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2898 (kbd_buffer_store_event_hold, gobble_input):
2899 (record_asynch_buffer_change) [USABLE_SIGIO]:
2900 (store_user_signal_events):
2901 No need to mess with signal mask.
2902 (gobble_input): If blocking input and there are terminals, simply
2903 set pending_signals to 1 and return. All hooks changed to not
2904 worry about whether input is blocked.
2905 (process_pending_signals): Clear pending_signals before processing
2906 them, in case a signal comes in while we're processing.
2907 By convention callers now test pending_signals before calling us.
2908 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2909 New functions, to support changes to blockinput.h.
2910 (handle_input_available_signal): Now extern.
2911 (reinvoke_input_signal): Remove. All uses replaced by
2913 (quit_count): Now volatile, since a signal handler uses it.
2914 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2915 All callers changed. Block SIGINT only if not already blocked.
2916 Clear sigmask reliably, even if Fsignal returns, which it can.
2917 Omit unnecessary accesses to volatile var.
2918 (quit_throw_to_read_char): No need to restore sigmask.
2919 * keyboard.c (gobble_input, handle_user_signal):
2920 * process.c (wait_reading_process_output):
2921 Call signal-handling code rather than killing ourselves.
2922 * lisp.h: Include <float.h>, for...
2923 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2924 (pending_signals): Now volatile.
2925 (syms_of_data): Now const if IEEE floating point.
2926 (handle_input_available_signal) [USABLE_SIGIO]:
2927 (terminate_due_to_signal, record_child_status_change): New decls.
2928 * process.c (create_process): Avoid disaster if memory is exhausted
2929 while we're processing a vfork, by tightening the critical section
2931 (send_process_frame, process_sent_to, handle_pipe_signal)
2932 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2934 (send_process): No need for setjmp/longjmp any more, since the
2935 SIGPIPE stuff is now gone. Instead, report an error if errno
2937 (record_child_status_change): Now extern. PID and W are now args.
2938 Return void, not bool. All callers changed.
2939 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2940 Remove. All uses removed. This bug should be fixed now in a
2942 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2943 and record the child status change directly. This avoids the
2944 need to futz with the signal mask.
2945 (process_fatal_action): Move here from emacs.c.
2946 (emacs_sigaction_flags): New function, containing
2947 much of what used to be in emacs_sigaction_init.
2948 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2949 caught by emacs, to make races less likely.
2950 (deliver_process_signal): Rename from handle_on_main_thread.
2952 (BACKTRACE_LIMIT_MAX): Now at top level.
2953 (thread_backtrace_buffer, threadback_backtrace_pointers):
2955 (deliver_thread_signal, deliver_fatal_thread_signal):
2956 New functions, for more-accurate delivery of thread-specific signals.
2957 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2958 (deliver_arith_signal): Handle in this thread, not
2959 in the main thread, since it's triggered by this thread.
2960 (maybe_fatal_sig): New function.
2961 (init_signals): New arg DUMPING so that we can be more accurate
2962 about whether we're dumping. Caller changed.
2963 Treat thread-specific signals differently from process-general signals.
2964 Block all signals while handling fatal error; that's safer.
2965 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2967 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2968 Ignore SIGPIPE unless batch.
2969 (emacs_backtrace): Output backtrace for the appropriate thread,
2970 which is not necessarily the main thread.
2971 * syssignal.h: Include <stdbool.h>.
2972 (emacs_raise): New macro.
2973 * xterm.c (x_connection_signal): Remove; no longer needed
2974 now that we use sigaction.
2975 (x_connection_closed): No need to mess with sigmask now.
2976 (x_initialize): No need to reset SIGPIPE handler here, since
2977 init_signals does this for us now.
2979 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2981 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2982 background rect may be larger (Bug#12245).
2984 2012-09-23 Chong Yidong <cyd@gnu.org>
2986 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2988 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2990 * .gdbinit: Just stop at fatal_error_backtrace.
2991 See Stefan Monnier's request in
2992 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2993 Remove no-longer-used query of system type.
2995 2012-09-22 Chong Yidong <cyd@gnu.org>
2997 * search.c (Freplace_match): Doc fix (Bug#12325).
2999 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3001 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3002 (Fline_end_position): Doc fix.
3004 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3006 2012-09-22 Chong Yidong <cyd@gnu.org>
3008 * dispextern.h (struct image_type): Add new slot, storing a type
3009 initialization function.
3011 * image.c (define_image_type): Call the image initializer function
3012 if it is defined. Arguments and return value changed.
3013 (valid_image_p, make_image): Callers changed.
3014 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3015 (gif_type, imagemagick_type, svg_type, gs_type):
3016 Add initialization functions.
3017 (Finit_image_library): Call lookup_image_type.
3018 (CHECK_LIB_AVAILABLE): Macro deleted.
3019 (lookup_image_type): Call define_image_type here, rather than via
3020 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3021 (syms_of_image): Move define_image_type calls for xbm_type and
3022 pbm_type to lookup_image_type.
3024 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3026 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3027 'idle_timers' from here ...
3028 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3029 lists, to avoid infloops when the timer does something stupid,
3030 like reinvoke itself with the same or smaller time-out.
3033 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3035 * window.c (Fsplit_window_internal): Handle only Qt value of
3036 Vwindow_combination_limit separately.
3037 (Qtemp_buffer_resize): New symbol.
3038 (Vwindow_combination_limit): New default value.
3041 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3043 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3044 the new overlay string. (Bug#10159)
3046 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3048 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3049 or that fprintf is async-signal-safe. POSIX doesn't require
3052 2012-09-22 Chong Yidong <cyd@gnu.org>
3054 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3057 2012-09-22 Kenichi Handa <handa@gnu.org>
3059 * composite.c (composition_reseat_it): Handle the case that a
3060 grapheme cluster is not covered by a single font (Bug#12352).
3062 2012-09-21 Chong Yidong <cyd@gnu.org>
3064 * image.c (define_image_type): Avoid adding duplicate types to
3065 image_types (Bug#12463). Suggested by Jörg Walter.
3067 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3069 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3070 (print_load_command_name): Add case LC_DATA_IN_CODE.
3071 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3073 2012-09-21 Glenn Morris <rgm@gnu.org>
3075 * eval.c (Frun_hook_with_args_until_success)
3076 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3078 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3080 * fileio.c (Ffile_selinux_context): Only call freecon when
3081 lgetfilecon succeeded.
3082 (Fset_file_selinux_context): Likewise. (Bug#12444)
3084 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3086 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3087 reordering, locate the cursor by calling set_cursor_from_row; if
3088 that fails, clear the desired glyph matrix before returning a
3089 failure indication to the caller. Fixes leaving garbled display
3090 when fast scrolling with a down-key. (Bug#12403)
3091 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3092 scrolling through multibyte text.
3094 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3096 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3097 calling mark_vectorlike since that's the one that marks the window.
3098 (mark_discard_killed_buffers): Mark the final cdr.
3099 * window.h (struct window): Move prev/next_buffers to the
3100 non-standard fields.
3101 * window.c (make_window): Initialize prev/next_buffers manually.
3103 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3105 Omit unused arg EXPECTED from socket hooks.
3106 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3107 * nsterm.m (ns_term_init):
3108 * termhooks.h (struct terminal.read_socket_hook):
3109 * w32inevt.c (w32_console_read_socket):
3110 * w32term.c (w32_read_socket):
3111 * xterm.c (XTread_socket):
3112 Omit unused arg EXPECTED. All callers changed.
3113 (store_user_signal_events): Return void, not int, since callers no
3114 longer care about the return value. All uses changed.
3116 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3118 * w32gui.h (XParseGeometry): Do not declare.
3120 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3122 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3123 Ignore 'expected'. See Eli Zaretskii in
3124 <http://bugs.gnu.org/12471#8> (last line).
3126 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3127 (XParseGeometry): Now static. Substitute extremal values for
3128 values that are out of range.
3130 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3132 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3134 * nsfns.m (XParseGeometry): Remove.
3135 (Fx_create_frame): Call x_set_offset to correctly interpret
3136 top_pos in geometry.
3138 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3139 (Fx_parse_geometry): If there is a space in string, call
3140 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3142 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3144 * search.c (scan_buffer): Use character positions in calls to
3145 region_cache_forward and region_cache_backward, not byte
3146 positions. (Bug#12196)
3148 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3149 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3151 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3152 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3153 emacs_blocked_malloc, now deleted.
3155 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3157 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3158 The workaround was for improving performance on Solaris 2.4, but
3159 is getting in the way now. Emacs will still work if someone is
3160 still running Solaris 2.4 in a museum somewhere; Sun dropped
3161 support for Solaris 2.4 in 2003.
3162 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3163 * process.c (create_process) [HAVE_WORKING_VFORK]:
3164 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3165 since Emacs no longer uses vfork on that platform.
3167 2012-09-17 Glenn Morris <rgm@gnu.org>
3169 * emacs.c: Use COPYRIGHT.
3171 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3173 Remove configure's --without-sync-input option (Bug#12450).
3174 When auditing signal-handling in preparation for cleaning it up,
3175 I found that SYNC_INPUT has race conditions and would be a real
3176 pain to fix. Since it's an undocumented and deprecated
3177 configure-time option, now seems like a good time to remove it.
3178 Also see <http://bugs.gnu.org/11080#16>.
3179 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3180 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3181 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3182 (malloc_hysteresis):
3183 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3184 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3185 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3186 (dont_register_blocks, bytes_used_when_reconsidered)
3187 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3188 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3189 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3190 Remove. All uses removed.
3191 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3192 implementation, one that depends on whether the new macro
3193 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3195 * atimer.c (run_timers, handle_alarm_signal):
3196 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3197 (handle_async_input, process_pending_signals)
3198 (handle_input_available_signal, init_keyboard):
3199 * nsterm.m (ns_read_socket):
3200 * process.c (wait_reading_process_output):
3201 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3202 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3204 * xterm.c (XTread_socket):
3206 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3207 * eval.c (handling_signal): Remove. All uses removed.
3208 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3209 All uses replaced with the SYNC_INPUT version.
3210 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3212 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3215 * font.c (Ffont_shape_gstring): Remove unused local.
3217 2012-09-16 Glenn Morris <rgm@gnu.org>
3219 * Makefile.in (clean): No longer run nextstep's clean.
3221 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3223 (ns-app): Move here from ns.mk, and simplify.
3224 (clean): Simplify nextstep entry.
3225 * ns.mk: Remove file.
3227 2012-09-17 Kenichi Handa <handa@gnu.org>
3229 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3230 not covert the last few charactes.
3232 2012-09-16 Kenichi Handa <handa@gnu.org>
3234 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3235 here, but just check the validity of glyphs in the glyph-string.
3237 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3239 * window.c (Fwindow_parameter, Fset_window_parameter):
3240 Accept any window as argument (Bug#12452).
3242 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3244 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3245 to ns_term_init to avoid memory leak.
3247 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3248 explicit retain/release.
3249 (ns_term_init): Only allow one display. Initialize outerpool and
3252 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3254 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3255 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3256 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3257 the Microsoft problem in a different way, by altering ../nt/config.nt.
3259 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3274 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3275 by lisp.h. This completes removal of setjmp.h inclusion
3276 erroneously announced in the previous commit. (Bug#12446)
3278 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3281 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3282 not defined as a macro. The latter happens on MS-Windows.
3285 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3287 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3288 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3289 Some instances of '#include <setjmp.h>' removed, if the
3290 only reason for the instance was because "lisp.h" was included.
3291 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3292 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3293 and _longjmp with the new symbols. Emacs already uses _setjmp if
3294 available, so this change affects only POSIXish hosts that have
3295 sigsetjmp but not _setjmp, such as some versions of Solaris and
3296 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3297 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3298 (png_load_body) [HAVE_PNG]:
3299 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3300 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3301 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3302 since PNG requires jmp_buf. This is the only exception to the
3303 general rule that we now use sys_setjmp and sys_longjmp.
3304 This exception is OK since this code does not change the signal
3305 mask or longjmp out of a signal handler.
3307 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3309 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3310 Include "syssignal.h", for 'main_thread'.
3312 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3314 Avoid out-of-range marker position (Bug#12426).
3315 * insdel.c (replace_range, replace_range_2):
3316 Adjust markers before overlays, as suggested by comments.
3317 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3318 Remove redundant check before calling offset_intervals.
3320 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3322 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3323 current buffer (Bug#12387).
3325 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3327 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3329 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3331 Use a more backwards-compatible timer format (Bug#12430).
3332 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3333 vector element, not from the 4th, since PSECS is now at the end.
3334 (Fcurrent_idle_time): Doc fix.
3336 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3338 Function to mark objects and remove killed buffers at once.
3339 * alloc.c (discard_killed_buffers): Rename to ...
3340 (mark_discard_killed buffers) ... new name. Add marking
3341 of remaining objects. Fix comment. Adjust users.
3342 (mark_object): Do not touch frame buffer lists here.
3343 * frame.c (delete_frame): Reset frame buffer lists here.
3345 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3347 Better workaround for GNOME bug when --enable-gcc-warnings.
3348 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3349 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3350 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3352 Simplify SIGIO usage (Bug#12408).
3353 The code that dealt with SIGIO was crufty and confusing, e.g., it
3354 played tricks like "#undef SIGIO" but these tricks were not used
3355 consistently. Simplify mostly by not #undeffing standard symbols,
3356 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3357 or not as we please) rather than "defined SIGIO" (standard symbol
3358 that we probably shouldn't #undef).
3359 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3360 Modules that need it can include it.
3361 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3362 * dispextern.h (ignore_sigio): New decl.
3363 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3364 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3365 * emacs.c (shut_down_emacs):
3366 * keyboard.c (kbd_buffer_store_event_hold):
3367 Use ignore_sigio rather than invoking 'signal' directly.
3368 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3370 (FIONREAD, SIGIO): Do not #undef.
3371 (tty_read_avail_input): Use #error rather than a syntax error.
3372 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3373 for I_PIPE, used by SETUP_SLAVE_PTY.
3374 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3375 * sysdep.c (croak): Remove; no longer needed. This bit of
3376 temporary code, with Fred N. Fish's comment that it's temporary,
3377 has been in Emacs since at least 1992!
3378 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3379 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3380 * syssignal.h (croak): Remove decl.
3381 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3382 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3383 now that we're termios-only.
3384 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3385 * term.c (dissociate_if_controlling_tty): Use #error rather than
3388 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3389 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3390 to work around GNOME bug 683906.
3391 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3392 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3393 This works around GCC bug 54561.
3395 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3397 More fixes for 'volatile' and setjmp/longjmp.
3398 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3399 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3400 (png_load_body) [HAVE_PNG]:
3401 (jpeg_load_body) [HAVE_JPEG]:
3402 New function, with most of the old parent function's body.
3403 (png_load) [HAVE_PNG]:
3404 (jpeg_load) [HAVE_JPEG]:
3405 Invoke the new function, to avoid longjmp munging our locals.
3406 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3407 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3408 longjmp is passed 2, as the C standard doesn't guarantee this.
3409 Instead, store the failure code into mgr->failure_code.
3411 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3413 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3414 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3415 (syms_of_keyboard): Remove support for unread-command-char.
3417 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3419 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3420 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3421 violation. (Bug#12426)
3423 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3425 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3427 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3429 * eval.c: Add `inhibit-debugger'.
3430 (Qinhibit_debugger): New symbol.
3431 (call_debugger): Bind it instead of Qdebug_on_error.
3432 (maybe_call_debugger): Test Vinhibit_debugger.
3433 (syms_of_eval): Define inhibit-debugger.
3434 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3435 (syms_of_xdisp): Remove inhibit-debug-on-message.
3437 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3439 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3440 If a nonvolatile local variable is written before a _longjmp to
3441 the frame containing the variable, and is read after the _longjmp,
3442 the value read is indeterminate. Some local variables of type
3443 'struct handler' and 'struct catchtag' are used in this way, so
3444 mark each of their slots as volatile if the slot can be set before
3445 _longjmp and read afterwards.
3446 * lisp.h (struct handler): var and chosen_clause are now volatile.
3447 (struct catchtag): val, next, and pdlcount are now volatile.
3449 * bidi.c (bidi_push_it, bidi_pop_it):
3450 * fns.c (copy_hash_table):
3451 * image.c (define_image_type):
3452 * keyboard.c (kbd_buffer_store_event_hold):
3453 * process.c (Fprocess_send_eof):
3454 * xfaces.c (x_create_gc) [HAVE_NS]:
3455 * xgselect.c (xg_select):
3456 Prefer assignment to memcpy when either will do.
3458 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3459 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3460 time an item is removed. No need to mark this function 'inline';
3461 the compiler knows better than we do.
3463 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3465 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3466 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3467 to change_frame_size (Bug#12388).
3468 (windowDidResize:): Pass YES to updateFrameSize.
3470 * nsterm.h: Add delay parameter to updateFrameSize.
3472 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3474 Discard killed buffers from deleted window and frame objects.
3475 This reduces an amount of references to killed buffers and
3476 helps GC to reclaim them faster.
3477 * alloc.c (discard_killed_buffers): New function.
3478 (mark_object): Use it for deleted windows and frames.
3479 (mark_object): If symbol's value is set up for a killed buffer
3480 or deleted frame, restore its global binding.
3481 * data.c (swap_in_global_binding): Add GC notice.
3482 (swap_in_symval_forwarding): Use convenient set_blv_where.
3483 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3484 * window.h: ... to here.
3486 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3488 Convenient macro to check whether the buffer is live.
3489 * buffer.h (BUFFER_LIVE_P): New macro.
3490 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3491 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3493 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3495 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3496 composition cases (Bug#12364).
3498 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3499 overhang of succeeding glyphs overlapping box cursor.
3501 * w32term.c (x_draw_glyph_string): Likewise.
3503 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3505 Simplify, document, and port floating-point (Bug#12381).
3506 The porting part of this patch fixes bugs on non-IEEE platforms
3507 with frexp, ldexp, logb.
3508 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3510 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3511 support, by removing commented-out code and briefly listing the
3512 C89 functions excluded. The commented-out stuff was confusing
3513 maintenance, e.g., we thought we needed cbrt but it was commented out.
3514 (logb): Remove decl; no longer needed.
3515 (isfinite): New macro, if not already supplied.
3516 (isnan): Don't replace any existing macro.
3517 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3518 are present on all C89 platforms.
3519 (Ffrexp): Do not special-case zero, as frexp does the right thing
3521 (Flogb): Do not use logb, as it doesn't have the desired meaning
3522 on hosts that use non-base-2 floating point. Instead, stick with
3523 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3524 frexp, to avoid getting an unspecified result.
3526 * xdisp.c (Qinhibit_debug_on_message): Now static.
3528 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3530 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3531 NSBezierPath (Bug#12131).
3533 2012-09-10 Chong Yidong <cyd@gnu.org>
3535 * fns.c (Fdelq, Fdelete): Doc fix.
3537 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3539 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3540 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3542 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3544 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3545 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3548 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3550 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3551 left fringe if the window has a left margin. This avoids leaving
3552 traces of the cursor because its leftmost pixel is not drawn over.
3554 * dispnew.c (update_window_line): When the left margin area of a
3555 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3556 that screen line. (Bug#12277)
3558 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3560 Assume C89 or later for math functions (Bug#12381).
3561 This simplifies the code, and makes it a bit smaller and faster,
3562 and (most important) makes it easier to clean up signal handling
3563 since we can stop worring about floating-point exceptions in
3564 library code. That was a problem before C89, but the problem
3565 went away many years ago on all practical Emacs targets.
3566 * data.c, image.c, lread.c, print.c:
3567 Don't include <math.h>; no longer needed.
3568 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3569 might be autoconfigured, as that never happens.
3571 * doprnt.c (DBL_MAX_10_EXP):
3572 * print.c (DBL_DIG):
3573 Remove. C89 or later always defines these.
3574 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3575 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3576 (arith_error, domain_error, domain_error2):
3577 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3578 no longer needed -- we simply return what C returns. All uses removed.
3579 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3581 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3582 Remove. All uses expanded, as these macros are no longer used
3583 more than once and are now more trouble than they're worth.
3584 (Ftan): Use tan, not sin / cos.
3585 (Flogb): Assume C89 frexp.
3586 (fmod_float): Assume C89 fmod.
3587 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3588 (init_floatfns): Remove. All uses removed.
3590 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3592 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3593 compositeToPoint for OSX < 10.6 (Bug#12390).
3595 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3597 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3598 This produces more-accurate results.
3600 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3602 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3603 changes (Bug#12088).
3605 2012-09-08 Chong Yidong <cyd@gnu.org>
3607 * syntax.c (Fstring_to_syntax): Doc fix.
3609 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3611 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3612 in the internal border.
3613 (x_set_window_size): Remove static variables and their usage.
3614 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3615 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3616 Remove fringe/internal border adjustment (Bug#11052).
3617 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3618 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3619 (ns_fix_rect_ibw): Remove.
3620 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3621 (ns_dumpglyphs_box_or_relief): Ditto.
3622 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3624 (ns_dumpglyphs_image): Ditto.
3625 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3627 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3628 their usage. Add fringe_extended_p and its use as in other terms.
3629 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3630 scroll bar was removed.
3631 (updateFrameSize): New function.
3632 (windowDidResize): Move code to updateFrameSize and call it.
3634 * nsterm.h (EmacsView): Add updateFrameSize.
3636 2012-09-07 Chong Yidong <cyd@gnu.org>
3638 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3640 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3642 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3644 More signal-handler cleanup (Bug#12327).
3645 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3646 Problem introduced when merging patches. Noted by Eli Zaretskii in
3647 <http://bugs.gnu.org/12327#67>.
3648 * floatfns.c: Comment fix.
3649 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3650 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3651 and anyway the declaration is harmless even if SIGDANGER is not defined.
3652 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3653 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3654 source files not surprisingly expected syssignal.h to define, or
3655 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3656 Include <sys/ioctl.h>, for FIONREAD.
3657 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3658 This eliminates a problem whereby other files mysteriously had
3659 to include "syssignal.h" before including "systty.h" if they
3660 wanted to use "#ifdef SIGIO".
3662 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3664 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3666 * w32.c (sigemptyset): Empty the set.
3667 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3669 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3671 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3673 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3674 (mark_object): Likewise for frame objects.
3676 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3678 * syssignal.h (handle_on_main_thread): Always declare,
3679 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3680 This ports to platforms without HAVE_PTHREAD.
3682 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3684 Signal-handler cleanup (Bug#12327).
3685 Emacs's signal handlers were written in the old 4.2BSD style with
3686 sigblock and sigmask and so forth, and this led to some
3687 inefficiencies and confusion. Rewrite these to use
3688 pthread_sigmask etc. without copying signal sets around. Also,
3689 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3690 'signal', and instead use functions that do not attempt to take
3691 over the system name space. This patch causes Emacs's text
3692 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3693 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3694 Do not include <signal.h> or "syssignal.h", as these
3695 modules do not use signals.
3696 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3697 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3698 Do not include <signal.h>, as "syssignal.h" does that for us now.
3699 * atimer.c (sigmask_atimers): New function.
3700 (block_atimers, unblock_atimers): New functions,
3701 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3703 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3704 no longer needed here.
3705 * emacs.c (main): Inspect existing signal handler with sigaction,
3706 so that there's no need to block and unblock SIGHUP.
3707 * sysdep.c (struct save_signal): New member 'action', replacing
3708 old member 'handler'.
3709 (save_signal_handlers, restore_signal_handlers):
3710 Use sigaction instead of 'signal' to save and restore.
3711 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3712 New function. All users of 'signal' modified to use set_sighandler
3713 if they're writeonly, and to use sys_signal if they're read+write.
3714 (emacs_sigaction_init, forwarded_signal): New functions.
3715 (sys_signal): Remove. All uses replaced by calls to sigaction
3716 and emacs_sigaction_init, or by direct calls to 'signal'.
3717 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3718 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3719 all uses replaced by pthread_sigmask etc. calls.
3720 * syssignal.h: Include <signal.h>.
3721 (emacs_sigaction_init, forwarded_signal): New decls.
3722 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3723 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3724 (sigmask, sys_sigmask): Remove; no longer needed.
3725 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3726 (sigblock, sigunblock, sigfree):
3727 (sigsetmask) [!defined sigsetmask]:
3728 Remove. All uses replaced by pthread_sigmask.
3729 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3730 no longer need to be replaced, and its typical old uses
3731 are now done via emacs_sigaction_init and sigaction.
3732 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3733 (sys_sigdel): Remove; unused.
3734 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3736 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3738 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3739 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3741 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3743 Explicitly mark buffer_defaults and buffer_local_symbols.
3744 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3745 mark_local_symbols here.
3746 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3747 since special buffers aren't marked here any more.
3748 (allocate_buffer): Chain new buffer with all_buffers here...
3749 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3751 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3752 (syms_of_buffer): Remove staticpro of the above.
3753 (init_buffer_once): Set names for buffer_defaults and
3754 buffer_local_symbols.
3756 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3758 Use bool for booleans in font-related modules.
3759 * font.c (font_intern_prop, font_style_to_value)
3760 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3761 (generate_otf_features, font_check_otf_features, font_check_otf)
3762 (font_match_p, font_list_entities, font_at):
3763 * fontset.c (fontset_id_valid_p, reorder_font_vector
3764 (fontset_find_font, Fset_fontset_font)
3765 (face_suitable_for_char_p) [0]:
3766 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3767 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3768 (m17n_flt_initialized, ftfont_shape_by_flt):
3769 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3770 * nsfont.m (nsfont_draw):
3771 * w32font.c (w32font_draw):
3772 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3773 Use bool for booleans.
3774 * font.h: Adjust to above API changes.
3775 (struct font, struct font_driver, struct font_driver_list):
3776 Use bool for booleans.
3777 (struct font): Remove useless member encoding_type.
3779 * fontset.c, xftfont.c: Omit unnecessary static decls.
3781 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3783 * alloc.c (mark_object): Revert window marking code
3784 since it's unsafe for the Fset_window_configuration.
3786 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3788 Fix race conditions with signal handlers and errno (Bug#12327).
3789 Be more systematic about preserving errno whenever a signal
3790 handler returns, even if it's not in the main thread. Do this by
3791 renaming signal handlers to distinguish between signal delivery
3792 and signal handling. All uses changed.
3793 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3794 * data.c (deliver_arith_signal): Rename from arith_error.
3795 * dispnew.c (deliver_window_change_signal): Rename from
3796 window_change_signal.
3797 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3798 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3799 * keyboard.c (deliver_input_available_signal): Rename from
3800 input_available_signal.
3801 (deliver_user_signal): Rename from handle_user_signal.
3802 (deliver_interrupt_signal): Rename from interrupt_signal.
3803 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3804 (deliver_child_signal): Rename from sigchld_handler.
3805 * atimer.c (handle_alarm_signal):
3806 * data.c (handle_arith_signal):
3807 * dispnew.c (handle_window_change_signal):
3808 * emacs.c (handle_fatal_signal, handle_danger_signal):
3809 * keyboard.c (handle_input_available_signal):
3810 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3811 * process.c (handle_pipe_signal, handle_child_signal):
3812 New functions, with the actual signal-handling code taken from the
3813 original respective signal handlers, sans the sporadic attempts to
3814 preserve errno, since that's now done by handle_on_main_thread.
3815 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3816 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3817 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3819 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3820 Move initialization of main_thread to sysdep.c's init_signals.
3821 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3822 our usage, and simplifies the mainline code.
3823 (record_child_status_change): New static function, as a helper
3824 for handle_child_signal, and with most of the old child handler's
3826 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3827 (handle_child_signal): Use the above.
3828 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3829 Moved here from emacs.c.
3830 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3831 code moved here from emacs.c's main function.
3832 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3833 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3834 This lets callers save and restore errno properly.
3836 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3838 Remove redundant or unused things here and there.
3839 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3840 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3841 * editfns.c (Fcompare_buffer_substrings): Likewise.
3842 * frame.h (struct terminal, struct font_driver_list):
3843 Remove redundant declarations.
3844 * window.h (Qleft, Qright): Likewise.
3846 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3848 Do not mark objects from deleted buffers, windows and frames.
3849 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3850 (mark_object): Likewise for windows and frames.
3852 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3854 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3855 buffer_defaults and buffer_local_symbols as valid objects.
3856 Return special value to denote them.
3858 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3860 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3861 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3862 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3863 (file_name_absolute_p, Fsubstitute_in_file_name):
3864 (check_executable, check_writable, Ffile_accessible_directory_p)
3865 (Fset_file_selinux_context, Fdefault_file_modes)
3866 (Finsert_file_contents, choose_write_coding_system)
3867 (Fwrite_region, build_annotations, a_write, e_write)
3869 * filelock.c (boot_time_initialized, get_boot_time)
3870 (get_boot_time_1, lock_file_1, within_one_second):
3871 * floatfns.c (in_float):
3872 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3873 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3874 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3875 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3876 * window.c (compare_window_configurations):
3877 Use bool for booleans.
3878 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3879 (Fdefault_file_modes): Now mode_t, not int, for modes.
3880 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3881 (internal_delete_file): Now returns void, not a (boolean) int,
3882 since nobody was looking at the return value.
3883 * lisp.h, window.h: Adjust to above API changes.
3885 * xdisp.c (set_message): Simplify and reindent last change.
3887 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3889 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3891 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3893 * eval.c (call_debugger): Make the function non-static so that we
3894 can call it from set_message.
3896 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3897 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3899 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3901 Give more-useful info on a fatal error (Bug#12328).
3902 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3903 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3904 of doing the work ourselves.
3905 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3906 do most of the work.
3907 (fatal_error_backtrace): New function, taken from the guts
3908 of the old fatal_error_signal, but with a new option to output
3910 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3911 info about the signal than just its number.
3912 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3913 * sysdep.c: Include <execinfo.h>
3914 (emacs_backtrace): New function, taken partly from the previous
3915 code of the 'die' function.
3916 (emacs_abort): Call fatal_error_backtrace rather than abort.
3918 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3920 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3921 eager (load-time) macro-expansion.
3922 * lisp.mk (lisp): Add macroexp.
3924 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3926 Simplify redefinition of 'abort' (Bug#12316).
3927 Do not try to redefine the 'abort' function. Instead, redo
3928 the code so that it calls 'emacs_abort' rather than 'abort'.
3929 This removes the need for the NO_ABORT configure-time macro
3930 and makes it easier to change the abort code to do a backtrace.
3931 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3932 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3933 Remove; sysdep.c's emacs_abort now takes its place.
3934 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3935 'abort' changed to use 'emacs_abort'.
3936 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3937 (abort) [!defined abort]: Rename to ...
3938 (emacs_abort): ... new name.
3939 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3940 the place of the old 'abort' in emacs.c.
3941 * w32.c, w32fns.c (abort): Do not #undef.
3942 * w32.c (emacs_abort): Rename from w32_abort.
3944 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3946 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3947 offsets[j].dv, since the y axis of the screen coordinates points
3948 down, while the y axis of the font definition coordinates points
3949 up. This fixes display of Arabic diacritics such as KASRA and
3950 KASRATAN. (Bug#11860)
3952 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3954 Be more systematic about _setjmp vs setjmp.
3955 * alloc.c (test_setjmp, mark_stack):
3956 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3957 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3958 (png_load, my_error_exit, jpeg_load):
3959 * process.c (send_process_trap, send_process):
3960 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3961 The underscored versions are up to 30x faster on some hosts.
3962 Formerly, the code used setjmp+longjmp sometimes and
3963 _setjmp+_longjmp at other times, with no particular reason to
3964 prefer setjmp+longjmp.
3966 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3968 Fix minor problem found by static checking.
3969 * buffer.c (Fdelete_all_overlays): Return nil.
3971 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3973 * buffer.c (Fdelete_all_overlays): New function.
3975 2012-09-03 Chong Yidong <cyd@gnu.org>
3977 * gtkutil.c: Add extern decl for Qxft.
3979 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3981 * emacs.c, eval.c: Use bool for boolean.
3982 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3983 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3984 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

3989 (maybe_call_debugger, Fbacktrace):
3990 * process.c (read_process_output, exec_sentinel):
3991 Use bool for booleans.
3992 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3993 All callers changed.
3994 * eval.c (interactive_p): Omit always-true boolean argument
3995 EXCLUDE_SUBRS_P. All callers changed.
3996 * dispextern.h, lisp.h: Reflect above API changes.
3997 * firstfile.c (dummy): Use the address of 'main', whose signature
3998 won't change, instead of the address of 'initialize', whose
3999 signature just changed from int to bool.
4000 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4001 * msdos.c (fatal_error_in_progress): ... from here.
4002 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4004 (redisplay_internal, unwind_redisplay): Simply clear
4005 REDISPLAYING_P when unwinding, instead of saving its previous,
4006 always-false value and then restoring it.
4008 Clean up some extern decls.
4009 Mostly, this hoists extern decls out of .c files and into .h files.
4010 That way, we're more likely to catch errors if the interfaces change.
4011 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4012 declare xg_mark_data.
4013 * dispextern.h (x_frame_parm_handlers):
4015 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4016 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4017 (Qultra_bold, Qoblique, Qitalic):
4018 Move extern decl here from .c file.
4019 * alloc.c (xg_mark_data) [USE_GTK]:
4021 * eval.c (Qlexical_binding):
4022 * fns.c (time) [!HAVE_UNISTD_H]:

4031 * xfont.c (x_clear_errors):
4032 * xterm.c (x_frame_parm_handlers):
4033 Remove now-redundant extern decls.
4034 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4035 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4037 * xfaces.c: Remove unnecessary static decls.
4038 * xterm.c (updating_frame): Remove decl of nonexistent object.
4040 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4041 when building globals.h, as the objects that are not built on
4042 this host are not needed to compile C files on this host.
4044 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4046 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4048 * frame.h: Add missing prototype for x_wm_set_size_hint.
4050 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4098 offset adjustment values separately for each cluster. (Bug#11860)
4100 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4101 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4102 about implicit conversions from integer to pointer.
4104 2012-09-01 Daniel Colascione <dancol@dancol.org>

4160 window system declarations.
4162 * frame.h: Move common functions here: set_frame_menubar,
4163 x_set_window_size, x_sync, x_get_focus_frame,
4164 x_set_mouse_position, x_set_mouse_pixel_position,
4165 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4195 the frames which are reachable from Vframe_list.
4196 * term.c (mark_ttys): Remove.
4197 (init_tty): Safely initialize 'top_frame' slot with Qnil.

4221 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4222 for GCC 4.7.1 x86-64.
4224 2012-08-30 Glenn Morris <rgm@gnu.org>
4226 * lread.c (init_lread): For out-of-tree builds, only add the
4227 source directory's site-lisp dir to the load-path if it exists,
4228 consistent with in-tree builds. (Bug#12302)
4230 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

4249 Handle click on close button as quit.
4251 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4252 Add window_closed and button_values. Add void as return value for
4253 add(Button|String|Split). addButton takes int instead of Lisp_Object.

4453 (map_sub_char_table):

4464 It was meant to be temporary and it often doesn't work,
4465 because when IDX has side effects the behavior of IDX==IDX
4466 is undefined. See Stefan Monnier in
4467 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4469 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

4478 as that's faster and simpler than static storage. Don't bother
4479 with the g_main_context_query overhead if g_main_context_pending
4480 says no events are pending.
4481 (gfds, gfds_size): Remove these static vars.
4482 (xgselect_initialize): Remove; no longer needed.
4483 All uses and decls removed.

4513 Use bool for booleans, instead of int.
4514 * lisp.h, process.h: Adjust prototypes to match above changes.
4515 * callint.c (Fcall_interactively): Don't assume the mark's
4516 offset fits in 'int'.

4528 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4529 Use bool for booleans, instead of int.
4530 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4531 since the 1-or-0 return value is always ignored anyway.
4532 (mmap_initialized_p):
4533 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4534 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4536 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4538 * bidi.c: Use bool for boolean.
4539 This is a bit more readable, and makes the text segment of bidi.o
4540 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4541 Presumably it's faster too.
4542 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
4544 (bidi_cache_find_level_change, bidi_cache_iterator_state)
4545 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
4546 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
4547 (bidi_explicit_dir_char, bidi_level_of_next_char)
4548 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4549 Use bool for booleans, instead of int.
4550 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4551 (bidi_unshelve_cache): Adjust decls to match code.
4553 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4555 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4558 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4560 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4561 * atimer.h: Include <stdbool.h>.
4563 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4565 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4566 compile time tests instead of run time tests on systems that do
4568 (FRAME_MAC_P): Remove leftover from deleted code.
4569 * frame.c (syms_of_frame): Remove leftover from deleted code.
4571 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4573 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4575 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4577 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4578 Otherwise, the compiler complains about (A?B:C) where B is void
4579 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4580 (fontset_add): Return void, for FONTSET_ADD.
4582 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4584 * alloc.c: Use bool for booleans.
4585 (gc_in_progress, abort_on_gc)
4586 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4587 (dont_register_blocks) [GC_MALLOC_CHECK]:
4588 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4589 (check_string_bytes, make_specified_string, memory_full)
4590 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4591 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4592 (mark_stack, valid_pointer_p, make_pure_string)
4593 (Fgarbage_collect, survives_gc_p, gc_sweep):
4594 Use bool for booleans, instead of int.
4595 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4596 Remove unused local.
4597 * alloc.c (PURE_POINTER_P):
4598 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4599 * editfns.c (Fformat):
4600 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4602 * fns.c (sweep_weak_table):
4603 * lisp.h (suppress_checking, push_message, survives_gc_p)
4604 (make_pure_string, gc_in_progress, abort_on_gc):
4605 * lread.c (readchar, read1):
4606 * print.c (Fprin1_to_string):
4607 * xdisp.c (push_message):
4608 Use bool for booleans affected directly or indirectly by
4611 Make recently-introduced setters macros.
4612 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4613 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4614 (set_fontset_default, set_fontset_fallback): Rename from their
4615 upper-case counterparts, and make them functions rather than macros.
4616 This is more consistent with the other recently-introduced setters.
4617 These don't need to be inline, since they're local.
4619 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4621 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4622 the loop (Bug#12247).
4624 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4626 * lisp.h (vcopy): Use memcpy rather than our own loop.
4627 This fixes a performance regression introduced by the recent
4628 addition of vcopy. This means 'vcopy' will need to be modified
4629 for a copying collector, but that's OK. Also, tighten the
4630 checking in the assertion.
4632 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4634 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4635 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4636 non-base glyph for the width of the base character, according to
4637 what x_draw_composite_glyph_string_foreground expects.
4638 Generate WADJUST value according to composition_gstring_width's
4639 expectations, to produce correct width of the composed character.
4640 Reverse the sign of the DU offset produced by ScriptPlace.
4642 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4644 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4646 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4648 Avoid direct writes to contents member of struct Lisp_Vector.
4649 * lisp.h (vcopy): New function to copy data into vector.
4650 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4651 * fns.c (Ffillarray): Use ASET.
4652 * keyboard.c (timer_check_2): Use AREF and ASET.
4653 (append_tool_bar_item, Frecent_keys): Use vcopy.
4654 * lread.c (read_vector): Use ASET.
4655 * msdos.c (Frecent_doskeys): Use vcopy.
4656 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4657 (Finternal_merge_in_global_face): Use ASET and vcopy.
4658 * xfont.c (xfont_list_pattern): Likewise.
4660 2012-08-21 Martin Rudalics <rudalics@gmx.at>
4662 * window.c (Fwindow_point): For the selected window always return
4663 the position of its buffer's point.
4664 (Fset_window_point): For the selected window always go in its
4665 buffer to the specified position.
4667 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4669 Setter macros for fontsets.
4670 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4671 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4672 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4675 2012-08-20 Glenn Morris <rgm@gnu.org>
4677 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4678 Don't assume that `ln -f' works.
4680 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4682 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4683 and later about non-assignments with no effect. See discussion at
4684 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4687 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4689 Inline setter functions for Lisp_Objects slots of struct specbinding.
4690 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
4693 2012-08-20 Martin Rudalics <rudalics@gmx.at>
4695 * window.c (select_window): Always make selected window's buffer
4698 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4700 Use AREF and ASET for docstrings of category tables.
4701 * category.h (CATEGORY_DOCSTRING): Use AREF.
4702 (SET_CATEGORY_DOCSTRING): Use ASET.
4703 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
4705 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4707 Inline setter functions for hash table members.
4708 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4709 (set_hash_hash, set_hash_index): Rename with _slot suffix.
4710 (set_hash_key_and_value, set_hash_index, set_hash_next)
4711 (set_hash_hash): New functions.
4712 * charset.c, fns.c: Adjust users.
4714 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4716 Inline getter and setter functions for per-buffer values.
4717 * buffer.h (per_buffer_default, set_per_buffer_default)
4718 (per_buffer_value, set_per_buffer_value): New functions.
4719 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
4720 * buffer.c, data.c: Adjust users.
4722 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
4724 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
4726 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4728 Rely on <config.h> + <unistd.h> to declare 'environ',
4729 as gnulib does this if the system doesn't.
4730 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4731 Remove declaration. MS-Windows declares it on stdlib.h which is
4732 included by conf_post.h.
4733 * emacs.c (environ) [DOUG_LEA_MALLOC]:
4734 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
4735 * vm-limit.c: Include <unistd.h>, for 'environ'.
4737 * unexaix.c, unexcoff.c: Include "mem-limits.h".
4738 (start_of_data): Remove decl; mem-limits.h provides it.
4740 * xdisp.c (handle_invisible_prop): Make it a bit faster
4741 and avoid a gcc -Wmaybe-uninitialized diagnostic.
4743 2012-08-19 Chong Yidong <cyd@gnu.org>
4745 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
4748 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
4750 * .gdbinit: Use call instead of set when calling a function in the
4753 * data.c (set_internal): Don't use set_blv_found.
4754 (Fkill_local_variable): Likewise.
4756 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4758 * nsfont.m (ns_ascii_average_width): Ensure the string
4759 ascii_printable is initialized with a null-terminated character
4760 array. Otherwise, it can contain undesired extra characters.
4762 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4764 port new setting code to Sun C 5.8 2005/10/13
4765 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4766 Return void, not Lisp_Object. Otherwise, the compiler
4767 complains about (A?B:C) where B is void and C is Lisp_Object
4768 when compiling CHAR_TABLE_SET, due to the recent change to
4769 the API of sub_char_table_set_contents.
4771 2012-08-18 Chong Yidong <cyd@gnu.org>
4773 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
4774 for the string case (Bug#3874).
4776 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4778 * buffer.h (BSET): Remove (Bug#12215).

4857 are compiled into code.
4858 (tset_param_alist): New setter function.
4860 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

4898 (set_buffer_overlays_after): Move here from buffer.h, and rename
4899 from buffer_overlays_set_after.

4927 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
4928 "set_char_table_parent (char_table, parent);".
4929 The old version was confusing because it used the same name
4930 'parent' for two different things.
4932 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
4934 Functions to get and set Lisp_Object fields of buffer-local variables.

4943 font spec, make the font's attributes take precedence over
4944 directly-specified attributes.
4945 (merge_face_ref): Recognize :font.
4947 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
4949 Do not use memcpy for copying intervals.
4950 * intervals.c (reproduce_interval): New function.

5601 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5602 * w32.c (init_environment): Change the default values of many
5603 environment variables in dflt_envvars[] to NULL, to avoid pushing
5604 them into environment when they were not already defined.
5605 Remove the code that deletes site-lisp subdirectories from the default
5606 value of EMACSLOADPATH, as it is no longer needed.
5607 (check_windows_init_file): Now external, not static.
5608 Use Vload_path as is, without adding anything, as this function is now
5609 called when Vload_path is already set up.
5611 * w32.h (check_windows_init_file): Add prototype.
5613 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

5620 installation tree, as appropriate.
5622 * callproc.c (init_callproc_1): Call decode_env_path instead of
5623 doing its equivalent by hand.

5625 the code that sets Vexec_path run on MS-Windows.
5627 * lread.c (init_lread): Add comments to #ifdef's.
5629 * msdos.c (dos_set_window_size, IT_update_begin)

5656 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5657 Remove unnecessary pointer casts.
5658 * alloc.c (record_xmalloc): New function.
5659 * lisp.h (record_xmalloc): New decl.
5660 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5661 more like a function. This is because the pointer cast is not
5662 needed. All uses changed.
5663 * print.c (print_string, print_error_message): Avoid length recalc.
5665 Improve fix for macroexp crash with debugging (Bug#12118).
5666 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5667 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5668 not supposed to be invoked from the garbage collector.

5670 (gc_aset): New function, which is like ASET but can be
5671 used in the garbage collector.

5687 headers (most versions of MinGW w32api don't).
5688 (get_security_info, create_symbolic_link)
5689 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

5696 have the required privileges.
5697 (get_file_security_desc_by_name): Rename from
5698 get_file_security_desc.

5700 with addition of handling of symlinks and support for 'lstat'.
5701 If possible, get file's attributes and security information by
5702 handle, not by name. Produce S_IFLNK bit for symlinks, when
5703 called from 'lstat'.
5704 (stat, lstat): New functions, call 'stat_worker'.
5705 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5706 symlinks when the underlying filesystem supports them.
5708 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5710 Fix macroexp crash on Windows with debugging (Bug#12118).
5711 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5712 checking subscripts; problem introduced with the recent
5713 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5714 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5715 since it's used in non-static inline functions now.
5717 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5718 Don't assume buffer size fits in 'int'. Remove unused local.

5735 * category.c (CATEGORY_INLINE):
5736 * character.c (CHARACTER_INLINE):
5737 * charset.c (CHARSET_INLINE):
5738 * composite.c (COMPOSITE_INLINE):
5739 * dispnew.c (DISPEXTERN_INLINE):
5740 * sysdep.c (SYSTIME_INLINE):
5741 Define to EXTERN_INLINE, so that the corresponding functions
5742 are compiled into code.
5743 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5744 (INLINE_HEADER_END): New macros.
5745 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5765 hard-coding the path separator.
5767 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5769 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5770 This how ASET and AREF are supposed to work, and makes
5771 it easier to think about future improvements. See
5772 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5773 * charset.h (set_charset_attr): New function.

6265 the fix for 12036 would have avoided some of the problems noted in
6266 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6267 would have been more obvious.

6279 not be usable in #if. This simplifies things.
6281 2012-07-26 Juanma Barranquero <lekktu@gmail.com>

6291 Adjust to changes in lisp.h and emacs.c, by using
6292 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6293 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6294 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6295 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6296 instead of gdb_valbits.

6301 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6302 (xreload, hook-run, hookpost-run): Remove.

6335 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6336 than macros. This simplifies debugging in the usual case, since
6337 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6338 and it allows expressions involving EMACS_INT casts.
6339 * .gdbinit (xreload): Simplify by using EMACS_INT cast.

6394 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6395 This avoids crash reported by Christoph Scholtes at
6396 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6398 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6400 * nsmenu.m (Popdown_data): New struct.

6425 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6426 as it's limited by the amount of memory, not by INT_MAX.

7204 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7205 * nsterm.m (ns_term_init):
7206 Avoid the need for strncpy, by using build_string or
7207 make_unibyte_string directly. Use dtoastr, not snprintf.
7208 * process.c (Fmake_network_process): Diagnose service names that
7209 are too long, rather than silently truncating them or creating
7210 non-null-terminated names.
7211 (Fnetwork_interface_info): Likewise, for interface names.
7212 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7213 Prefer sprintf to strncat.
7214 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

7220 Clarify fallback case.
7222 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

7240 Optimize pure C strings initialization.
7241 * lisp.h (make_pure_string): Fix prototype.
7242 (build_pure_c_string): New function, defined as static inline. This
7243 provides a better opportunity to optimize away calls to strlen when
7244 the function is called with compile-time constant argument.
7245 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7246 argument, adjust users accordingly. Use build_pure_c_string where
7248 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7249 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7250 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7252 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7254 Avoid calls to strlen in miscellaneous functions.
7255 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7256 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7257 * lread.c (openp): Likewise.
7259 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7261 Avoid calls to strlen in path processing functions.
7262 * fileio.c (file_name_as_directory): Add comment. Change to add
7263 srclen argument and return the length of result. Adjust users
7265 (directory_file_name): Fix comment. Change to add srclen argument,
7266 swap 1st and 2nd arguments to obey the common convention.
7267 Adjust users accordingly.
7268 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7270 2012-07-10 Glenn Morris <rgm@gnu.org>
7272 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

7277 * s/gnu.h (DATA_START): Move definitions to configure.
7279 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7280 We include usg5-4-common.h, which defines them both.
7282 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7283 O_RDONLY already includes it).
7285 Stop ns builds setting the EMACSLOADPATH environment variable.
7286 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7287 Now it does not set EMACSLOADPATH, just returns the load-path string.
7288 * nsterm.h: Update accordingly.
7289 * lread.c [HAVE_NS]: Include nsterm.h.
7290 (init_lread) [HAVE_NS]: Use ns_load_path.

7293 2012-07-09 Glenn Morris <rgm@gnu.org>
7295 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7296 since the included bsd-common.h does so.
7298 Stop ns builds setting the EMACSPATH environment variable.
7299 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7300 (ns_init_paths): Do not set EMACSPATH.
7301 * nsterm.h (ns_exec_path): Add it.
7302 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7305 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7307 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7309 * process.c (wait_reading_process_output): 'waitchannels' was unset
7310 when read_kbd || !NILP (wait_for_cell); fix this.
7312 Add GCC-style 'const' attribute to functions that can use it.
7313 * character.h (char_resolve_modifier_mask):
7314 * keyboard.h (make_ctrl_char):
7315 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7322 Declare the dummy function with ATTRIBUTE_CONST.
7323 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7324 Add decls with ATTRIBUTE_CONST.
7326 Minor improvements to make_formatted_string.
7327 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7328 where int is good enough, as vsprintf returns an int.
7329 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7331 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7333 Use make_formatted_string to avoid double length calculation.
7334 * lisp.h (make_formatted_string): New prototype.

7358 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7360 Move marker debugging code under MARKER_DEBUG.
7361 * marker.c (MARKER_DEBUG): Move marker debugging code under
7362 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7363 for bootstrap with --enable-checking (~3x slowdown reported
7364 by Juanma Barranquero <lekktu@gmail.com>).
7365 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7367 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7369 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7370 See <http://bugs.gnu.org/11825#29>.
7372 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7374 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7375 has no font, use the frame's font. (Bug#11813)
7376 (display_line): Add commentary about displaying truncation glyphs
7378 (produce_special_glyphs): Move here from term.c.
7380 * term.c (produce_special_glyphs): Move to xdisp.c.
7382 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7385 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7387 * xdisp.c (display_line): Avoid warning about implicit declaration
7390 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7392 * lisp.h: Remove empty conditional.
7394 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7396 * lread.c (load_path_check): Now static.
7398 Fix some minor --with-ns problems found by static checking.
7399 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7400 (x_set_font) [!HAVE_X_WINDOWS]:
7401 * image.c (xpm_load_image) [HAVE_NS]:
7402 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7403 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7404 Remove unused local.
7405 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7406 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7407 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7408 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7409 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7410 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7411 Fix pointer signedness problem.
7412 * xfaces.c (FRAME_X_FONT_TABLE):
7413 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7415 2012-07-07 Glenn Morris <rgm@gnu.org>
7417 * lread.c (load_path_check): New function, split from init_lread.
7418 (init_lread): Reorganize. Motivation:
7419 If EMACSLOADPATH is set, check/warn about that rather than the
7420 defaults, which we are not going to use. Hence we can remove
7421 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7422 Don't warn if site-lisp directories are missing.
7423 If not installed, start from a blank load-path, since
7424 PATH_LOADSEARCH refers to the eventual installation directories.
7426 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7428 Support truncation and continuation glyphs on GUI frames, when
7429 fringes are disabled. (Bug#11832)
7430 * xdisp.c (init_iterator): Get dimensions of truncation and
7431 continuation glyphs even if on GUI frames.
7432 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7433 or both, are absent.
7434 (start_display, move_it_in_display_line_to): Handle the case of a
7435 GUI frame without a fringe to display continuation or truncation
7437 (insert_left_trunc_glyphs): Support GUI frames: make sure
7438 truncation glyphs overwrite enough glyphs from the current line to
7439 have sufficient space in pixels.
7440 (display_line): Support truncation and continuation glyphs on GUI
7441 frames. If some spare pixels are left on the line after inserting
7442 the truncation glyphs, fill that space with a stretch glyph of a
7443 suitably computed width.
7445 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7446 produce_glyphs, to support GUI sessions.
7448 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7450 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7452 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7454 Do not require float-time's arg to fit in time_t (Bug#11825).
7455 This works better on hosts where time_t is unsigned, and where
7456 float-time is applied to the (negative) difference between two times.
7457 * editfns.c (decode_time_components): Last arg is now double *,
7458 not int *, and means to store all the result as a double, without
7459 worrying about whether the seconds part fits in time_t.
7460 All callers changed.
7461 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7462 All callers changed.
7463 (Ffloat_time): Do not fail merely because the specified time falls
7464 outside of time_t range.
7466 2012-07-07 Glenn Morris <rgm@gnu.org>
7468 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
7469 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

7472 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
7474 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7475 Update dependencies.
7477 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7479 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7481 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

7483 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7484 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7485 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7486 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7488 * xfont.c (compare_font_names): Redo to omit the need for casts.
7490 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7492 * xfns.c (Fx_change_window_property): Doc fix.
7493 * w32fns.c (Fx_change_window_property): Doc fix.
7495 * w32fns.c (Fx_window_property): Accept the same arguments as the
7496 X Windows version. Doc fix.
7497 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7499 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7500 Eli Zaretskii <eliz@gnu.org>
7502 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7503 Windows-specific code from nt/config.nt moved here.
7504 Obsolete settings removed.
7506 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7508 * process.c: Avoid unnecessary calls to gettime.
7509 (wait_reading_process_output): Don't get the time of day
7510 when gobbling data immediately and not waiting, as there's no need
7511 for it in that case. This removes a FIXME.
7513 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7515 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7516 is defined (Bug#11768).
7518 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7520 Fix marker debugging code.
7521 * marker.c (byte_char_debug_check): Do not perform the check
7522 if buffer is not multibyte.
7523 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7524 Call byte_char_debug_check with correct arguments.
7526 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7528 Compile marker debugging code only if ENABLE_CHECKING is defined.
7529 * marker.c (byte_char_debug_check, count_markers):
7530 Use only if ENABLE_CHECKING is defined.
7531 (byte_debug_flag): Remove.
7532 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7533 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7535 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7537 Avoid code repetition in marker-related functions.
7538 * marker.c (attach_marker): New function.
7539 (Fset_marker, set_marker_restricted, set_marker_both)
7540 (set_marker_restricted_both): Use it.
7541 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7542 Consistently rename charno to charpos.
7543 (marker_position): Add eassert.
7544 (marker_byte_position): Convert to eassert.

7563 * window.c (save_window_save): Likewise.
7565 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7567 Do not use Fdelete_overlay in delete_all_overlays
7568 to avoid redundant calls to unchain_overlay.
7569 * buffer.c (drop_overlay): New function.
7570 (delete_all_overlays, Fdelete_overlay): Use it.
7571 * minibuf.c (get_minibuffer): Fix comment.
7573 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7575 Port to OpenBSD 5.1 amd64.
7576 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7577 This is needed for OpenBSD, and should be harmless on all BSD systems.
7578 Also, include <sys/sysctl.h>, as it should be available on all
7579 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7580 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7581 use p_pid member, not kp_proc.pid.
7583 2012-07-06 Glenn Morris <rgm@gnu.org>
7585 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7587 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7589 More xmalloc and related cleanup.
7590 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
7591 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
7592 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
7593 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
7594 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
7595 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
7596 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
7597 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7598 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7600 Omit needless casts involving void * pointers and allocation.
7601 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7602 as the former is more robust if P's type is changed.
7603 Prefer xzalloc to xmalloc + memset 0.
7604 Simplify malloc-or-realloc to realloc.
7605 Don't worry about xmalloc returning a null pointer.
7606 Prefer xstrdup to xmalloc + strcpy.
7607 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7609 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7610 alloca of a constant.
7612 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7614 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7615 hscroll is larger than the line width. Fixes long and futile
7616 looping inside extend_face_to_end_of_line (on a TTY) producing
7617 glyphs that are not needed and thrown away.
7619 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7621 * marker.c (set_marker_restricted_both): Simplify by using
7624 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

7634 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
7635 followed by gtk_box_set_homogeneous (Bug#11768).
7636 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7637 (update_theme_scrollbar_width, xg_create_scroll_bar):
7638 Use gtk_scrollbar_new (Bug#11768).
7639 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
7640 (is_box_type): New function (Bug#11768).

7647 * xdisp.c (window_hscroll_limited): New function.
7648 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7649 coordinates when window's hscroll is set to insanely large
7652 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7654 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
7655 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
7657 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7660 * lisp.h (xzalloc): New prototype. Omit needless casts.

7715 * fileio.c (time_error_value): Check the right error number.
7716 Problem reported by Troels Nielsen in
7717 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
7719 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7721 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7722 This should be fixed in a better way; see Eli Zaretskii in
7723 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7724 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7726 * fileio.c (time_error_value): Rename from special_mtime.
7727 The old name's problems were noted by Eli Zaretskii in
7728 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7730 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7731 This variable's comment says Emacs needs at least one GDB-visible
7732 symbol of type enum pvec_type, to work around GDB problems.
7733 The symbol's value doesn't matter.
7735 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7736 that causes compilation to fail on pre-C99 compilers.
7738 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7740 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

7743 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7745 * buffer.c (init_buffer_once): Fix initialization of
7746 headers for buffer_defaults and buffer_local_symbols.
7747 Reported by Juanma Barranquero <lekktu@gmail.com>.
7749 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7751 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7752 * lisp.h (enum pvec_type): Use fewer bits.
7753 (PSEUDOVECTOR_SIZE_BITS): New constant.
7754 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7755 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7756 change in pvec_type.
7757 (PSEUDOVECTOR_TYPEP): New macro.
7758 (TYPED_PSEUDOVECTORP): Use it.
7759 * fns.c (internal_equal): Adapt code to extract pvectype.

7761 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
7762 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
7763 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7764 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7765 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7766 abusing vector->header.next.nbytes.
7767 (live_vector_p): Use PVEC_TYPE.
7768 (mark_object): Adapt code to extract pvectype. Use switch.
7770 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7772 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7773 Tighten new eassert a bit.
7775 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7777 Fix compilation with --enable-gcc-warnings and -O1
7779 * doprnt.c (doprnt): Change type of tem to int, initialize
7780 to avoid compiler warning. Add eassert.
7781 * search.c (simple_search): Initialize match_byte to avoid
7782 compiler warning. Add eassert.
7784 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7786 Avoid weird behavior with large horizontal scrolls.
7787 Without this change, for example, large hscroll values would
7788 mess up Emacs's display on Fedora 15 x86, presumably due to
7789 overflows in int calculations in the display code.
7790 Also, if buffers had long lines, Emacs would freeze.
7791 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7792 (set_window_hscroll): New function, containing the old guts of
7793 Fset_window_hscroll. Return the clipped value.
7794 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7795 This avoids the need to check against PTRDIFF_MAX.
7797 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7799 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7801 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7803 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7805 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7806 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7807 since GCC 4.4.6 issues a bogus warning for them.
7809 Fix bugs in file timestamp newness comparisons.
7810 * fileio.c (Ffile_newer_than_file_p):
7811 * lread.c (Fload): Use full timestamp resolution of files,
7812 not just the 1-second resolution, so that files that are only
7813 slightly newer still count as newer.
7814 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7815 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7817 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7819 * fileio.c: Improve handling of file time marker. (Bug#11852)
7820 (special_mtime): New function.
7821 (Finsert_file_contents, Fverify_visited_file_modtime):
7822 Use it to set special mtime values consistently.
7824 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7826 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7827 marker for non-existing file. (Bug#11852)
7829 2012-07-03 Glenn Morris <rgm@gnu.org>
7831 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7832 and did not make it into globals.h).
7834 2012-07-03 Tom Tromey <tromey@redhat.com>
7836 * window.c (Fset_window_margins, Fset_window_fringes)
7837 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7838 * textprop.c (Fprevious_property_change): No longer static.
7839 * syntax.c (Fsyntax_table_p): No longer static.
7840 * process.c (Fget_process, Fprocess_datagram_address): No longer

7861 * intervals.h: Remove EXFUNs.
7862 * fontset.h: Remove EXFUN.

7867 * w32term.h: Remove EXFUNs.
7868 * window.h: Remove EXFUNs.

7870 * xterm.h: Remove EXFUN.
7872 2012-07-03 Glenn Morris <rgm@gnu.org>
7874 * lisp.h (Frandom): Make it visible to C.
7875 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7876 buffer for invisible buffers. (Bug#1229)
7878 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7880 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7881 values which aren't power of 2.
7882 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7883 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7886 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7888 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7890 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7892 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7894 * alloc.c (allocate_vector_block): Remove redundant
7895 calls to mallopt if DOUG_LEA_MALLOC is defined.
7896 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7897 avoid calls to mallopt if zero_vector is returned.
7899 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7901 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7902 is enabled, avoid dereferencing NULL current_sblock if
7905 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7907 Cleanup basic buffer management.
7908 * buffer.h (struct buffer): Change layout to use generic vector
7909 marking code. Fix some comments. Change type of 'clip_changed'
7910 to bitfield. Remove unused #ifndef old.
7911 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7912 (GET_OVERLAYS_AT): Fix indentation.
7913 (for_each_per_buffer_object_at): New macro.

7917 * alloc.c (allocate_buffer): Adjust to match new layout of
7918 struct buffer. Fix comment.
7919 (mark_overlay): New function.

7921 Lisp area of struct buffer.
7922 (mark_object): Use it. Adjust marking of misc objects
7923 and related comments.
7925 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7927 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7928 wrapper that is not needed because the wrapped code is a no-op (zero
7929 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7930 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7932 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7934 * alloc.c (mark_buffer): Simplify. Remove prototype.
7935 (mark_object): Add comment. Reorganize marking of vector-like
7936 objects. Use CHECK_LIVE for all vector-like objects except buffers
7937 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7938 Avoid redundant calls to mark_vectorlike for bool vectors.
7940 2012-06-30 Glenn Morris <rgm@gnu.org>
7942 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7944 * epaths.in (PATH_SITELOADSEARCH): New.
7945 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7946 This is rather than relying on --enable-locallisppath elements
7947 having "site-lisp" in their names. (Bug#10208#25, 11658)
7949 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7951 * w32proc.c (sys_select): Accept and ignore one more argument.
7953 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7955 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7956 (pselect) [!MS_DOS]: Redirect to sys_select.
7958 * sysdep.c: Don't include dos.h and dosfns.h.
7960 * process.c (sys_select):
7961 * msdos.c (sys_select): Accept one more argument and ignore it.
7963 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7964 adapt data types and code to that.
7967 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7968 which clashes with the gnulib function of the same name.
7970 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7972 * font.c (font_style_to_value, font_style_symbolic)
7973 (font_prop_validate_style): Add type checks for values in
7976 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7978 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7981 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7983 * xdisp.c (try_window_id): Undo last change.
7985 * w32.c (getwd): Adjust commentary about startup_dir.
7986 (init_environment): Always call sys_access, even in non-MSVC
7987 builds. Don't chdir to the directory of the Emacs executable.
7988 This undoes code from 1997 which was justified by the need to
7989 "avoid conflicts when removing and renaming directories". But its
7990 downside was that every relative file name was being interpreted
7991 relative to the directory of the Emacs executable, which can never
7992 be TRT. In particular, it broke sys_access when called with
7993 relative file names.
7994 (sys_access): Map GetLastError to errno.
7996 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7998 * window.h (struct window): Change type of 'fringes_outside_margins'

8002 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8005 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8007 * gnutls.c (emacs_gnutls_handshake):
8008 Add QUIT to make the loop interruptible.
8010 2012-06-29 Glenn Morris <rgm@gnu.org>
8012 * charset.c (init_charset): Make lack of etc/charsets fatal.
8014 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8016 * editfns.c (region_limit): Fix type mismatch.
8018 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8020 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8021 undefined. Convert from xassert to eassert.
8022 * nsmenu.m: Convert from xassert to eassert.
8023 * nsterm.m: Likewise.
8025 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8027 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8029 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8031 Avoid integer overflow on scroll-left and scroll-right.
8032 * window.c (HSCROLL_MAX): New macro.
8033 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8034 overflow when requested scroll falls outside ptrdiff_t range.
8036 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8038 * window.h (struct window): Change type of 'hscroll',
8039 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8040 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8041 Adjust users accordingly.
8042 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8043 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8044 from EMACS_INT to ptrdiff_t.
8045 (make_window): Omit redundant initialization.
8047 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8049 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8051 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8053 * window.h (struct window): Change type of 'use_time' and
8054 'sequence_number' from Lisp_Object to int.
8055 * frame.c (make_frame): Adjust users accordingly.

8062 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
8063 enabled with --enable-checking=[all,glyphs] configure option.
8064 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8065 adjust comments accordingly.

8116 avoid GCC warning about unused macro.
8118 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8120 * alloc.c (allocate_string): Omit intervals initialization.
8121 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8122 as in make_pure_string and make_pure_c_string.
8124 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8126 * alloc.c (allocate_string): Fix last change.
8128 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

8131 to memset, add explicit initialization where appropriate.

8147 when building with Clang.
8149 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

8183 * w32proc.c (sys_spawnve): Likewise.
8184 * xterm.c (x_term_init): Likewise.
8186 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8188 Use sprintf return value instead of invoking strlen on result.
8189 In the old days this wasn't portable, since some sprintf
8190 implementations returned char *. But they died out years ago and
8191 Emacs already assumes sprintf returns int.
8192 Similarly for float_to_string.
8193 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8194 * ccl.c (ccl_driver):
8195 * character.c (string_escape_byte8):

8198 * print.c (print_object):
8199 * xdisp.c (message_dolog):
8200 * xfns.c (syms_of_xfns):
8201 Use sprintf or float_to_string result to avoid need to call strlen.
8202 * data.c (Fnumber_to_string):
8203 Use make_unibyte_string, since the string must be ASCII.
8204 * lisp.h, print.c (float_to_string): Now returns int length.
8205 * term.c (produce_glyphless_glyph):
8206 Use sprintf result rather than recomputing it.
8208 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8209 * Makefile.in (ALL_CFLAGS):
8210 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
8211 * gmalloc.c, regex.c: Include <config.h> unconditionally.
8213 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8215 * dispextern.h (xstrcasecmp): Define to library function
8216 strcasecmp if available.
8217 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

8232 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
8234 * gtkutil.c (get_utf8_string): Remove redundant assignment.
8235 sprintf already null-terminates its output.
8237 * xfns.c (x_window): Remove redundant cast.
8239 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8241 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
8242 `const char *' to `char *' to avoid compiler warning.
8244 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8246 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8247 instead of truncating it to 63 (admittedly a generous limit).
8249 * process.c: Fix spelling and caps in comments.
8251 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
8253 * emacs.c (setpgrp): Remove definition, unused.

8299 * sound.c (sound_warning, parse_sound):
8300 Remove unnecessary forward decls.
8302 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8304 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
8305 * lisp.h (WAIT_READING_MAX): New macro.
8306 * dispnew.c (Fsleep_for, sit_for):
8307 * keyboard.c (kbd_buffer_get_event):
8308 * process.c (Faccept_process_output):
8309 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8310 This improves on the previous patch, which introduced a bug
8311 when time_t is unsigned and as wide as intmax_t.
8312 See <http://bugs.gnu.org/9000#51>.
8314 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8316 * dispnew.c (sit_for, Fsleep_for):
8317 * keyboard.c (kbd_buffer_get_event):

8330 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
8331 Privately reported by Herbert J. Skuhra.
8332 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
8334 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
8335 not make_lisp_timeval, when the argument is of type EMACS_TIME.
8337 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8339 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
8340 last argument of make_unibyte_string.
8342 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
8343 language ID in the event parameters.
8345 * w32term.c (w32_read_socket): Put the new keyboard codepage into
8346 event.code, not the obscure "character set ID".
8348 2012-06-23 Chong Yidong <cyd@gnu.org>
8350 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
8352 2012-06-23 Eli Zaretskii <eliz@gnu.org>

8369 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
8370 Privately reported by Herbert J. Skuhra.
8371 [__FreeBSD__]: Remove "*/" typo after "#include".

8377 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8379 Support higher-resolution time stamps (Bug#9000).
8380 The time stamps are only nanosecond-resolution at the C level,
8381 since that's the best that any real-world system supports now.
8382 But they are picosecond-resolution at the Lisp level, as that's
8383 easy, and leaves room for future OS improvements.
8385 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8388 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8389 Don't get current time unless it's needed.
8391 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8392 now provides it if it's absent.
8393 (start_atimer): Port to higher-res time stamps.
8394 Check for time stamp overflow. Don't get current time more
8395 often than is needed.
8397 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8398 Include systime.h, not time.h.
8399 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8401 * dired.c: Include stat-time.h.
8402 (Ffile-attributes): File times now have higher resolution.
8404 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8405 (struct image): Timestamp now has higher resolution.
8407 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8408 has at least microseconds now. All uses removed.
8409 (update_frame, update_single_window, update_window, update_frame_1)
8410 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8411 (duration_to_sec_usec): Remove; no longer needed.
8413 * editfns.c (time_overflow): Now extern.
8414 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8415 (float-time, Fformat_time_string, Fcurrent_time_string)
8416 (Fcurrent_time_zone): Accept and generate higher-resolution
8418 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
8419 (decode_time_components, lisp_seconds_argument): New functions.
8420 (make_time): Now static.
8421 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8422 Report an error if the time is invalid, rather than having the caller
8425 * fileio.c: Include <stat-time.h>
8426 (Fcopy_file): Copy higher-resolution time stamps.
8427 Prefer to set the time stamp via a file descriptor if that works.
8428 (Fset_file_times, Finsert_file_contents, Fwrite_region)
8429 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8430 (Fvisited_file_modtime, Fset_visited_file_modtime):
8431 Support higher-resolution time stamps.
8433 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8435 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8437 * image.c (prepare_image_for_display, clear_image_cache)
8438 (lookup_image): Port to higer-resolution time stamps.
8440 * keyboard.c (start_polling, bind_polling_period):
8441 Check for time stamp overflow.
8442 (read_char, kbd_buffer_get_event, timer_start_idle)
8443 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8444 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8445 Port to higher-resolution time stamps. Do not assume time_t is signed.
8446 (decode_timer): New function. Timers are now vectors of length 9,
8447 not 8, to accommodate the picosecond component.
8448 (timer_check_2): Use it.
8450 * nsterm.m (select_timeout, timeval_subtract): Remove.
8451 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8452 as they're a bit more accurate and handle overflow better.
8453 (ns_select): Change prototype to be compatible with pselect.
8454 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8455 * nsterm.h (ns_select): Adjust prototype.
8457 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8458 us-resolution time stamps.
8459 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8461 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8463 * lisp.h (time_overflow): New decl.
8464 (wait_reading_process_output): First arg is now intmax_t, not int,
8465 to accommodate larger waits.
8467 * process.h (struct Lisp_Process.read_output_delay):
8468 Now counts nanoseconds, not microseconds.
8469 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8471 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8472 (wait_reading_process_output):
8473 Port to ns-resolution time stamps.
8474 (Faccept_process_output, wait_reading_process_output):
8475 Check for time stamp overflow. Do not assume time_t is signed.
8476 (select_wrapper): Remove; we now use pselect.
8477 (Fprocess_attributes): Now generates ns-resolution time stamps.
8479 * sysdep.c: Include utimens.h. Don't include utime.h
8480 or worry about struct utimbuf; gnulib does that for us now.
8481 (gettimeofday): Remove; gnulib provides a substitute.
8482 (make_timeval): New function.
8483 (set_file_times): Now sets ns-resolution time stamps.
8484 New arg FD; all uses changed.
8485 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8486 (system_process_attributes):
8487 Now returns ns-resolution time stamp. All uses changed.
8488 Check for time stamp overflow.
8490 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8491 provides a substitute now.
8493 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8494 since it guarantees struct timespec.
8495 (EMACS_TIME): Now struct timespec, so that we can support
8496 ns-resolution time stamps.
8497 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8498 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8499 (EMACS_USECS): Remove.
8500 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8501 so multiply the arg by 1000 before storing it.
8502 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8504 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8505 Port to ns-resolution time stamps.
8506 (EMACS_TIME_NEG_P): Remove; replaced by....
8507 (EMACS_TIME_SIGN): New macro.
8508 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8509 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8510 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8511 (make_timeval, make_lisp_time, decode_time_components): New decls.
8512 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8513 that it mishandled time_t overflow. You can't compare by subtracting!
8514 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8515 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8517 * term.c: Include <sys/time.h>.
8518 (timeval_to_Time): New function, for proper overflow wraparound.
8519 (term_mouse_position, term_mouse_click): Use it.
8521 * undo.c (record_first_change): Support higher-resolution time stamps
8523 (Fprimitive_undo): Use them when restoring time stamps.
8525 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8526 (w32_get_internal_run_time):
8527 Port to higher-resolution Emacs time stamps.
8528 (ltime): Now accepts single 64-bit integer, as that's more convenient
8531 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8533 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8534 for compatibility with pselect. Support ns-resolution time stamps.
8536 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8538 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8539 Check for time stamp overflow, and support ns-resolution time stamps.
8541 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8542 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8543 (timeval_subtract): Remove; no longer needed.
8544 (XTflash, XTring_bell, x_wait_for_event):
8545 Port to ns-resolution time stamps. Don't assume time_t is signed.
8547 2012-06-22 Chong Yidong <cyd@gnu.org>
8549 * xdisp.c (x_consider_frame_title): Revert last change.
8551 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8553 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8554 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8555 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8556 staticidx goes up to 1597 out of 1600 = 0x640.)
8558 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8560 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8561 Otherwise, the umask might be mistakenly 0 while handling input signals.
8563 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
8565 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

8570 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
8571 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
8572 access to `contents' member of Lisp_Vector objects with AREF and ASET
8575 2012-06-19 Chong Yidong <cyd@gnu.org>
8577 * frame.c (delete_frame): When selecting a frame on a different
8578 text terminal, do not alter the terminal's top-frame.

8581 frame's selected window and its terminal's top-frame.
8582 (unwind_format_mode_line): Restore them.
8583 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8585 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8586 since tty frames can be explicitly named.
8587 (prepare_menu_bars): Likewise.
8589 * term.c (Ftty_top_frame): New function.
8591 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8593 Port byte-code-meter to modern targets.
8594 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8595 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8596 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8597 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

8830 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8831 Use an inline function on all platforms when using the union type,
8832 since this is simpler and 'static inline' can be used portably

8976 * doprnt.c (doprnt): Truncate multibyte char correctly.
8977 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8978 would mishandle a string argument "Xc" if X was a multibyte
8979 character of length 2: it would truncate after X's first byte
8980 rather than including all of X.

9063 and 'double' in a couple of places.
9065 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9067 * xdisp.c (handle_stop): Detect whether we have overlay strings
9068 loaded by testing it->current.overlay_string_index to be
9069 non-negative, instead of checking whether n_overlay_strings is
9070 positive. (Bug#11587)

9080 * search.c (search_buffer): Remove calls to
9081 r_alloc_inhibit_buffer_relocation, as it is now called by
9082 maybe_unify_char, which was the cause of relocation of buffer text
9085 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9087 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9088 for the duration of call to load_charset, to avoid problems with
9089 callers of maybe_unify_char that access buffer text through C
9092 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9093 decrement the inhibition flag, instead of just setting or
9096 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9098 Remove obsolete '#define static' cruft.
9099 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9100 This #undef was "temporary" in 2000; it is no longer needed
9101 now that '#define static' has gone away.
9102 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9103 (gray_bitmap_bits): Remove; no longer needed.
9104 All uses replaced with definiens.
9105 * xterm.c: Include "bitmaps/gray.xbm".
9107 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9109 Clean up __executable_start, monstartup when --enable-profiling.
9110 The following changes affect the code only when profiling.
9111 * dispnew.c (__executable_start): Rename from safe_bcopy.
9112 Define only on platforms that need it.
9113 * emacs.c: Include <sys/gmon.h> when profiling.
9114 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9115 (__executable_start): Remove decl, since lisp.h does it now.
9116 (safe_bcopy): Remove decl; no longer has that name.
9117 (main): Coalesce #if into single bit of code, for simplicity.
9118 Cast pointers to uintptr_t, since standard libraries want integers
9120 * lisp.h (__executable_start): New decl.
9122 2012-05-31 Glenn Morris <rgm@gnu.org>
9124 * image.c (Fimagemagick_types): Doc fix.
9126 2012-05-30 Jim Meyering <meyering@redhat.com>
9128 * callproc.c (Fcall_process_region): Include directory component

9143 * lread.c (read1): Tiny simplification.
9145 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9147 Do not create empty overlays with the evaporate property (Bug#9642).
9148 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9149 Bug#9642, but explicitly check that the buffer the overlay would
9150 be moved to is live and rearrange lines to make sure that errors
9151 will not put the overlay in an inconsistent state.
9152 (Fdelete_overlay): Cosmetics.
9154 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9156 * w32term.c (my_bring_window_to_top): New function.
9157 (x_raise_frame): Use handle returned by DeferWindowPos, which
9158 could be different from the original one.
9159 Call my_bring_window_to_top instead of my_set_foreground_window.
9162 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9163 by calling BringWindowToTop.
9165 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9166 (WM_EMACS_END): Increase by one.
9168 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9170 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9171 This avoids undefined behavior that might cause the eassert
9172 to not catch an out-of-range value.
9174 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9176 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9177 Update dependencies.
9179 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9181 * bidi.c (bidi_mirror_char): Fix last change.
9183 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9185 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9186 when referring to sectname field in printf format.
9188 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9190 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9191 Only r_alloc_inhibit_buffer_relocation needed to be added;
9192 the others were already declared.
9194 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9195 before checking whether it's out of range. Put the check inside
9197 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9199 2012-05-27 Ken Brown <kbrown@cornell.edu>
9201 * callproc.c (Fcall_process): Restore a line that was accidentally
9202 commented out in the 2011-02-13 change (bug#11547).
9204 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9206 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9207 defined on ralloc.c.
9209 * buffer.c [REL_ALLOC]: Remove prototypes of
9210 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9211 they are now on lisp.h.
9213 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9215 * search.c (search_buffer): Use it to inhibit relocation of buffer
9216 text while re_search_2 is doing its job, because re_search_2 is
9217 passed C pointers to buffer text. (Bug#11519)
9219 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9222 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9223 state after an additional call to move_it_in_display_line_to, keep
9224 the values of it->max_ascent and it->max_descent found for the
9226 (pos_visible_p): Revert the comparison against bottom_y to what it
9227 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9230 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9232 Fix coding-related core dumps with gcc -ftrapv.
9233 The code was computing A - B, where A and B are pointers, and B is
9234 random garbage. This can lead to core dumps on platforms that
9235 have special pointer registers, and it also leads to core dumps on
9236 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9237 A - B only when B is initialized properly.
9238 * coding.c (coding_set_source, coding_set_destination): Return void.
9239 (coding_change_source, coding_change_destinations): New functions,
9240 with the old behaviors of coding_set_source and coding_set_destination.
9241 All callers that need an offset changed to use these new functions.
9243 2012-05-26 Glenn Morris <rgm@gnu.org>
9245 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9247 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9249 Extend mouse support on W32 text-mode console.
9250 * xdisp.c (draw_row_with_mouse_face):
9251 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9253 * w32console.c: Include window.h.
9254 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9256 (initialize_w32_display): Initialize mouse-highlight data.
9258 * w32inevt.c: Include termchar.h and window.h.
9259 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9260 moves, call note_mouse_highlight. If help_echo changed, call
9261 gen_help_event to produce help-echo message in the echo area.
9262 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9265 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9267 * lread.c (read1): Simplify slightly to avoid an overflow warning
9268 with GCC 4.7.0 on x86-64.
9270 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9272 * bidi.c (bidi_mirror_char): Revert last change: an int is
9273 definitely wide enough here.
9275 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9277 Fix integer width and related bugs (Bug#9874).
9278 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9279 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
9280 (string_bytes, check_sblock, allocate_string_data):

9285 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9287 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9288 (allocate_pseudovector):
9289 Use int, not EMACS_INT, where int is wide enough.
9290 (inhibit_garbage_collection, Fgarbage_collect):
9291 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9292 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9293 int might not be wide enough.
9294 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9295 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

9297 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9298 (bidi_level_of_next_char, bidi_move_to_visually_next):
9299 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9300 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9301 (Fkill_buffer, Fset_buffer_major_mode)
9302 (advance_to_char_boundary, Fbuffer_swap_text)

9305 (overlay_strings, recenter_overlay_lists)
9306 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9307 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9308 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9309 (Foverlay_recenter, last_overlay_modification_hooks_used)
9310 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9311 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9312 (validate_region): Omit unnecessary test for b <= e,
9313 since that's guaranteed by the previous test.
9314 (adjust_overlays_for_delete): Avoid pos + length overflow.
9315 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9316 (report_overlay_modification):
9317 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9318 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9319 Omit pointer cast, which isn't needed anyway, and doesn't work
9320 after the EMACS_INT -> ptrdiff_t change.
9321 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9322 * buffer.h: Adjust decls to match defn changes elsewhere.
9323 (struct buffer_text, struct buffer):

9326 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9327 not int, to avoid needless 32-bit limit on 64-bit hosts.
9328 (exec_byte_code): Use tighter memory-full test, one that checks
9329 for alloca overflow. Don't compute the address of the object just
9330 before an array, as that's not portable. Use EMACS_INT, not
9331 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9332 * callint.c (Fcall_interactively):
9333 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9334 * callproc.c (call_process_kill, Fcall_process):
9335 Don't assume pid_t fits into an Emacs fixnum.

9344 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9345 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9346 (casify_object): Avoid integer overflow when overallocating buffer.
9347 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9348 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9349 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9350 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9351 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9352 integers are now checked earlier. All uses replaced with XINT.
9354 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9355 For CCL_MapSingle, check that content and value are in int range.
9356 (ccl_driver, Fregister_code_conversion_map):
9357 Check that Vcode_version_map_vector is a vector.
9358 (resolve_symbol_ccl_program): Check that vector header is in range.
9359 Always copy the vector, so that we can check its contents reliably
9360 now rather than having to recheck each instruction as it's being
9361 executed. Check that vector words fit in 'int'.
9362 (ccl_get_compiled_code, Fregister_ccl_program)
9363 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9364 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9365 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9366 contents are in range.
9367 (Fccl_execute_on_string): Check that status is in range.
9368 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9369 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9370 Accept and return EMACS_INT, not int, because callers can pass values
9372 (c_string_width, strwidth, lisp_string_width, chars_in_text)

9375 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9376 (string_escape_byte8, Fget_byte):
9377 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9378 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9379 avoid mishandling large integers.
9380 * character.h: Adjust decls to match defn changes elsewhere.
9381 * charset.c (load_charset_map_from_file, find_charsets_in_text)

9389 (Fdefine_charset_internal): Check ranges here, more carefully.
9390 Don't rely on undefined behavior with signed left shift overflow.
9391 Don't assume unsigned int fits into fixnum, or that fixnum fits
9392 into unsigned int. Don't require max_code to be a valid fixnum;
9393 that's not true for gb10830 4-byte on a 32-bit host. Allow
9394 invalid_code to be a cons, for the same reason. Require code_offset
9395 to be a character. Avoid int overflow if max_char is close
9397 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9398 this is intended anyway and avoids some undefined behavior.
9399 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9400 INDEX_TO_CODE_POINT, as that's what it expects.
9401 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9402 * charset.h (DECODE_CHAR): Return int, not unsigned;
9403 this is what was intended anyway, and it avoids undefined behavior.
9404 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9405 integer-overflow issues.
9406 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9407 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9408 where the argument is EMACS_INT, and this behavior is not intended.
9409 * chartab.c (Fmake_char_table, Fset_char_table_range)
9410 (uniprop_get_decoder, uniprop_get_encoder):
9411 Don't assume fixnum fits in int.
9412 * cmds.c (move_point): New function, that does the gist of
9413 Fforward_char and Fbackward_char, but does so while checking
9414 for integer overflow more accurately.
9415 (Fforward_char, Fbackward_char): Use it.
9416 (Fforward_line, Fend_of_line, internal_self_insert)
9417 (internal_self_insert):
9418 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9419 Fix a FIXME, by checking for integer overflow when calculating
9420 target_clm and actual_clm.

9452 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9453 (consume_chars): Rewrite to not calculate an address outside buffer.
9454 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
9455 Don't access memory outside of the args array.
9456 (Fdefine_coding_system_internal): Check for charset-id overflow.
9457 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
9458 result of ENCODE_CHAR.
9459 * coding.h: Adjust decls to match defn changes elsewhere.

9476 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9477 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
9478 Do not attempt to compute the address of the object just before a
9479 buffer; this is not portable.
9481 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9482 (Faset): Use int, not EMACS_INT, where int is wide enough.
9483 (Fstring_to_number): Don't assume fixnums fit in int.

10204 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10206 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10208 * unexaix.c: Port to more-recent AIX compilers.
10209 (report_error, report_error_1, make_hdr, copy_sym)
10210 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10211 Make arguments const char *, not char *, to avoid violations of C
10212 standard and to fix some AIX warnings reported by Gilles Pion.
10214 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10216 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10217 already have overlays loaded.
10218 (handle_single_display_spec): Before returning without displaying
10219 fringe bitmap, synchronize the bidi iterator with the main display
10220 iterator, by calling iterate_out_of_display_property.
10221 (iterate_out_of_display_property): Detect buffer iteration by
10222 testing that it->string is a Lisp string.
10223 (get_next_display_element): When the current object is exhausted,
10224 and there's something on it->stack, call set_iterator_to_next to
10225 proceed with what's on the stack, instead of returning zero.
10226 (set_iterator_to_next): If called at the end of a Lisp string,
10227 proceed to consider_string_end without incrementing string
10228 position. Don't increment display vector index past the end of
10229 the display vector. (Bug#11417)
10230 (pos_visible_p): Don't report a position visible when move_it_to
10231 stopped at the last line of window, which happens to be scanned
10232 backwards by the bidi iteration. (Bug#11464)
10234 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10236 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10237 and right-margin display specs even if the spec is invalid or we
10238 are on a TTY, and thus unable to display on the fringes.
10239 That's because the text with the property will not be displayed anyway,
10240 so we need to signal to the caller that this is a "replacing"
10241 display spec. This fixes display when the spec is invalid or we
10244 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10246 * unexaix.c (make_hdr): Fix typo in prototype.
10247 This bug broke the build on AIX. Problem reported by Gilles Pion.
10249 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10251 * keyboard.c (kbd_buffer_get_event): Read special events also in
10252 batch mode. (Bug#11415)
10254 2012-05-12 Glenn Morris <rgm@gnu.org>
10256 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10258 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10260 * lisp.mk (lisp): Add newcomment.elc.
10262 2012-05-12 Glenn Morris <rgm@gnu.org>
10264 * Makefile.in (MKDIR_P): New, set by configure.
10265 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10267 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10269 Remove unused function hourglass_started.
10270 * dispextern.h (hourglass_started):
10271 * w32fns.c (hourglass_started):
10272 * xdisp.c (hourglass_started): Remove.
10274 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10276 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10277 Update dependencies.
10279 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10281 * xgselect.c (xg_select): Put maxfds+1 into a var.
10282 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10284 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10286 2012-05-10 Dave Abrahams <dave@boostpro.com>
10288 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10289 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10291 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10293 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10294 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10295 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10296 Initialize xd_registered_buses.
10298 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10300 Untag more efficiently if USE_LSB_TAG.
10301 This is based on a proposal by YAMAMOTO Mitsuharu in
10302 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10303 For an admittedly artificial (nth 8000 longlist) benchmark on
10304 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10305 Emacs's overall text size by 1%.
10306 * lisp.h (XUNTAG): New macro.
10307 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10308 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10309 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10310 * eval.c (Fautoload):
10311 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10312 * frame.h (XFRAME): Use XUNTAG.
10314 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10315 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10316 Remove unportable assumptions about print widths of types like
10318 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10319 intptr_t when converting between pointer and integer, to avoid GCC
10320 warnings about wrong width.
10322 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10324 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10325 stack for each reader_thread, instead of defaulting to 8MB
10326 determined by the linker. This avoids failures in creating
10327 subprocesses on Windows 7, see the discussion in this thread:
10328 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10330 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10332 Fix up display of the *Minibuf-0* buffer in the mini window.
10333 * keyboard.c (read_char): Don't clear the echo area if there's no
10335 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10336 contents of *Minibuf-0*) if there's no message displayed in its stead.
10338 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10340 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10343 2012-05-06 Chong Yidong <cyd@gnu.org>
10345 * lisp.mk (lisp): Update.
10347 2012-05-05 Jim Meyering <meyering@redhat.com>
10349 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10351 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10353 * data.c (PUT_ERROR): New macro.
10354 (syms_of_data): Use it. Add new error type `user-error'.
10355 * undo.c (user_error): New function.
10356 (Fprimitive_undo): Use it.
10357 * print.c (print_error_message): Adjust print style for `user-error'.
10358 * keyboard.c (user_error): New function.
10359 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10361 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10363 Do not limit current-time-string to years 1000..9999.
10364 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10365 (Fcurrent_time_string): Support any year that is supported by the
10366 underlying localtime representation. Don't use asctime, as it
10367 has undefined behavior for years outside the range -999..9999.
10369 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10371 Fix race conditions involving setenv, gmtime, localtime, asctime.
10372 Without this fix, interrupts could mess up code that uses these
10373 nonreentrant functions, since setting TZ invalidates existing
10374 tm_zone or tzname values, and since most of these functions return
10375 pointers to static storage.
10376 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10377 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10378 Grow the critical sections to include not just invoking
10379 localtime/gmtime, but also accessing these functions' results
10380 including their tm_zone values if any, and any related TZ setting.
10381 (format_time_string): Last arg is now struct tm *, not struct tm **,
10382 so that the struct tm is saved in the critical section.
10383 All callers changed. Simplify allocation of initial buffer, partly
10384 motivated by the fact that memory allocation needs to be outside
10385 the critical section.
10387 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10389 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10390 with RESET_INTERVAL.
10392 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10393 Remove duplicated buffer name initialization.
10395 2012-05-02 Jim Meyering <jim@meyering.net>
10397 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10399 * xfns.c (x_window): Use xstrdup (Bug#11375).
10401 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10403 * xdisp.c (pos_visible_p): If already at a newline from the
10404 display string before the 'while' loop, don't walk back the glyphs
10405 from it3.glyph_row. Solves assertion violation when the display
10406 string begins with a newline (egg.el). (Bug#11367)
10408 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10410 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10413 2012-05-01 Glenn Morris <rgm@gnu.org>
10415 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10416 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10417 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10418 All were removed before 23.1.
10420 * dispnew.c: Remove HAVE_LIBNCURSES test;
10421 it is always true on relevant platforms.
10423 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10424 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10426 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10428 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10430 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10431 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10434 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10436 Do not avoid creating empty evaporating overlays (Bug#9642).
10437 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10438 That is, do not delete an evaporating overlay if it becomes
10439 empty after its bounds are adjusted to fit within its buffer.
10440 This fix caused other problems, and I'm reverting it until we get
10441 to the bottom of them.
10443 2012-04-27 Chong Yidong <cyd@gnu.org>
10445 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10447 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10449 * xdisp.c (pos_visible_p): If the window start position is beyond
10450 ZV, start the display from buffer beginning. Prevents assertion
10451 violation in init_iterator when the minibuffer window is scrolled
10452 via the scroll bar.
10454 * window.c (window_scroll_pixel_based): Likewise.
10456 2012-04-27 Chong Yidong <cyd@gnu.org>
10458 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10460 2012-04-27 Glenn Morris <rgm@gnu.org>
10462 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10463 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10465 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10467 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10468 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10470 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10472 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10473 display element, check also the underlying string or buffer
10474 character. (Bug#11341)
10476 * w32menu.c: Include w32heap.h.
10477 (add_menu_item): If the call to AppendMenuW (via
10478 unicode_append_menu) fails, disable Unicode menus only if we are
10479 running on Windows 9X/Me.
10481 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10483 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10484 (xgetint): Add missing shift for LSB tags.
10486 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10488 * keyboard.c (read_char): Don't wipe echo area for select window
10489 events: These might get delayed via `mouse-autoselect-window'
10492 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10494 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10495 manipulation of :loaded-from data.
10497 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10499 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10500 now a cons (bug#11311).
10502 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10504 Do not create empty overlays with the evaporate property (Bug#9642).
10505 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10506 if it becomes empty after its bounds are adjusted to fit within
10507 its buffer. Without this fix, in a nonempty buffer (let ((o
10508 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10509 yields an empty overlay that has the evaporate property, which is
10510 not supposed to happen.
10512 Fix minor GTK3 problems found by static checking.
10513 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10514 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10515 (struct _EmacsFixedClass, emacs_fixed_get_type):
10516 Move decls here from emacsgtkfixed.h, since they needn't be public.
10517 (emacs_fixed_get_type): Now static.
10518 (emacs_fixed_class_init): Omit unused local.
10519 (emacs_fixed_child_type): Remove; unused.
10520 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10521 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10522 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10523 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10524 (EMACS_FIXED_GET_CLASS): Remove; unused.
10525 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
10527 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
10528 Problem reported by Juanma Barranquero for Windows -Wunused-function.
10530 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10532 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10533 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10534 (__malloc_size_t, __malloc_ptrdiff_t):
10535 Remove. All uses removed, replaced by the definiens if needed,
10536 since we can assume C89 or better now.
10537 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

10545 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10546 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10547 Define using prototypes, not old style.
10548 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
10549 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
10550 (align): Don't assume that signed integer overflow wraps around.
10551 Omit unused local var.
10552 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
10553 (_free_internal_nolock, memalign, mallochook, reallochook):
10554 Omit no-longer-needed casts.
10555 (valloc): Use getpagesize, not __getpagesize.
10556 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
10557 (struct hdr): The 'magic' member is now size_t, not unsigned long.
10559 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
10561 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
10563 Move functions from C to Lisp. Make non-blocking method calls
10564 the default. Implement further D-Bus standard interfaces.
10566 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

10584 (xd_get_connection_address): Rename from xd_initialize.
10585 Return cached address.
10586 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.

10606 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10608 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
10609 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
10610 Do not assume ptrdiff_t is the same width as 'int'.
10612 * alloc.c: Handle unusual debugging option combinations.
10613 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
10614 since the two debugging options are incompatible.
10615 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
10617 (mem_init, mem_insert, mem_insert_fixup):
10618 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
10619 (NEED_MEM_INSERT): Remove; no longer needed.
10621 2012-04-22 Leo Liu <sdl.web@gmail.com>

10625 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10627 * sysdep.c [__FreeBSD__]: Minor cleanups.
10628 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10629 Use Emacs indenting style more consistently. Avoid some casts.
10630 Use 'double' consistently rather than mixing 'float' and 'double'.
10632 2012-04-21 Eduard Wiebe <usenet@pusto.de>

10648 * print.c (print_preprocess): Only check print_depth if print-circle
10650 (print_object): Check for cycles even when print-circle is nil and
10651 print-gensym is t, but only check print_depth if print-circle is nil.

10655 * process.c (wait_reading_process_output): If EIO occurs on a pty,
10656 set the status to "failed" and ensure that sentinel is run.
10658 2012-04-20 Glenn Morris <rgm@gnu.org>
10660 * process.c (Fset_process_inherit_coding_system_flag)
10661 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

10671 farther than the first row after the header line, if any.
10672 Don't consider the header-line row as "partially visible", even if
10673 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
10675 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
10677 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"

10684 * Makefile.in (C_WARNINGS_SWITCH): Remove.
10685 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
10686 (ALL_CFLAGS): Use new macros rather than old.
10687 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.

10689 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
10690 -Wunused-result, -Wunused-variable. This should go away once
10691 the Emacs and Gnulib regex code is merged.
10692 (xmalloc, xrealloc): Now static.
10694 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

10711 New extern decls, to avoid calling undeclared functions.
10712 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
10713 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
10714 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10715 (NEED_MEM_INSERT): New macro.
10716 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10717 Remove one incorrect comment and fix another.

10731 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
10732 Remove decls. This fixes an "It stinks!".
10734 * alloc.c (which_symbols): Fix alignment issue / type clash.
10736 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
10738 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
10739 (struct Lisp_Misc_Any): Likewise.
10740 (struct Lisp_Free): Likewise.
10741 * alloc.c (union aligned_Lisp_Symbol): Define.

10751 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
10752 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
10753 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10754 * s/netbsd.h, s/sol2-6.h:
10755 Remove definition of GC_MARK_STACK, since the default now works.
10756 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
10757 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
10758 no longer the default.
10759 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
10761 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
10763 * lread.c (lisp_file_lexically_bound_p):
10764 Fix hang at ";-*-\n" (bug#11238).
10766 2012-04-14 Eli Zaretskii <eliz@gnu.org>
10768 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
10769 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

10780 2012-04-13 Reuben Thomas <rrt@sc3d.org>
10782 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
10784 2012-04-11 Daniel Colascione <dancol@dancol.org>
10786 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10787 against is gone. It's better to use vfork now so that when Cygwin
10788 gains a new, working vfork, we use it automatically (bug#10398).
10790 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
10792 * window.c (save_window_save): Obey window-point-insertion-type.

10808 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
10810 * w32.c (w32_delayed_load): Record the full path of the library
10811 being loaded (bug#10424).
10813 2012-04-09 Glenn Morris <rgm@gnu.org>
10815 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
10816 not just in the obarray, before snarfing them. (Bug#11036)

10821 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
10823 * process.c (make_process):
10824 * process.h: Add integer `gnutls_handshakes_tried' member to

10833 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10834 attempts per process (connection).
10836 2012-04-09 Chong Yidong <cyd@gnu.org>
10838 * eval.c (Fuser_variable_p, user_variable_p_eh)
10839 (lisp_indirect_variable): Functions deleted.
10840 (Fdefvar): Caller changed.
10842 * callint.c (Finteractive, Fcall_interactively):
10843 * minibuf.c (Fread_variable): Callers changed.
10845 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10847 * xdisp.c (set_cursor_from_row): If the display string appears in
10848 the buffer at position that is closer to point than the position
10849 after the display string, display the cursor on the first glyph of
10850 the display string. Fixes cursor display when a 'display' text
10851 property immediately follows invisible text. (Bug#11094)
10853 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10855 composite.c: use 'double' consistently
10856 * composite.c (get_composition_id): Use 'double' consistently
10857 instead of converting 'float' to 'double' and vice versa; this is
10858 easier to understand and avoids a GCC warning.
10860 2012-04-09 Glenn Morris <rgm@gnu.org>
10862 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10863 preparation for dumping it with emacs. (Bug#4789)

10884 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
10885 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10886 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10887 objects, as mark_maybe_pointer will catch them otherwise.
10888 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
10889 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

10900 * makefile.w32-in (OBJ2): Add xml.$(O).
10901 (GLOBAL_SOURCES): Add xml.c.
10902 ($(BLD)/xml.$(O)): New dependency list.
10904 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10905 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10906 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10907 [!WINDOWSNT]: New macros.
10908 (init_libxml2_functions, libxml2_loaded_p): New functions.
10909 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10910 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10911 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10912 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10914 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10915 Call init_libxml2_functions before calling libxml2 functions.
10916 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10918 * emacs.c: Don't include libxml/parser.h.
10919 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10920 xmlCleanupParser directly.
10922 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10924 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10926 * indent.c (Fvertical_motion): If there is a display string at
10927 point, use it.vpos to compute how many lines to backtrack after
10928 move_it_to point. (Bug#11133)
10930 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10932 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10933 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10934 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10935 macros related to unification of CJK characters. For the details,
10936 see the discussion following the message here:
10937 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10939 2012-04-04 Chong Yidong <cyd@gnu.org>
10941 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10943 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10945 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
10946 instead of alloca. (Bug#11138)
10948 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
10950 * w32menu.c (is_simple_dialog): Properly check lisp types.
10953 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10955 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10956 position we get to after a call to move_it_to fails the
10957 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10958 only if we wind up in a string from display property. (Bug#11063)
10960 * window.c (Fdelete_other_windows_internal): Invalidate the row
10961 and column information about mouse highlight, so that redisplay
10962 restores it after reallocating the glyph matrices. (Bug#7464)
10964 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10965 string comes from a `display' text property, use the buffer
10966 position of that property as if we actually saw that position in
10968 (move_it_by_lines): Remove the assertion that
10969 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10970 violated when there's a before-string at the beginning of a line.
10973 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10975 * xdisp.c (append_space_for_newline): If the default face was
10976 remapped, use the remapped face for the appended newline.
10977 (extend_face_to_end_of_line): Use the remapped default face for
10978 extending the face to the end of the line.
10979 (display_line): Call extend_face_to_end_of_line when the default
10980 face was remapped. (Bug#11068)

11002 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11003 (command_loop_1): Use it; inhibit selection update for

11008 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11010 2012-03-25 Kenichi Handa <handa@m17n.org>
11012 * dispextern.h (struct glyph): Change the bit length of
11013 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11015 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11017 * s/ms-w32.h (tzname): Include time.h before redirecting to

11022 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11025 * xterm.c (XTread_socket): Only modify handling_signal if
11026 !SYNC_INPUT. (Bug#11080)
11028 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11030 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11031 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11032 when fetching a multibyte character consumes more bytes than
11033 CHAR_BYTES returns, due to unification of CJK characters in
11034 string_char. (Bug#11073)
11036 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11038 * process.c (wait_reading_process_output): Handle pty disconnect
11039 by refraining from sending oneself a SIGCHLD (bug#10933).
11041 2012-03-22 Chong Yidong <cyd@gnu.org>
11043 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11045 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11046 Mark string as coming from a prefix property.
11047 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11048 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11050 2012-03-21 Chong Yidong <cyd@gnu.org>
11052 * xfaces.c (Vface_remapping_alist): Doc fix.
11054 2012-03-20 Eli Zaretskii <eliz@gnu.org>

11068 it fit in a valid range (Bug#11003).
11070 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11072 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11073 that is not from display property, accept the row as a "cursor
11074 row" if one of the string's character has a non-nil `cursor'
11075 property. Fixes cursor positioning when there are newlines in
11076 overlay strings, e.g. in icomplete.el. (Bug#11035)
11078 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11080 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11082 2012-03-12 Chong Yidong <cyd@gnu.org>
11084 * eval.c (inhibit_lisp_code): Rename from
11085 inhibit_window_configuration_change_hook; move from window.c.
11087 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11088 * window.c (run_window_configuration_change_hook)
11089 (syms_of_window): Callers changed.

11109 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11112 2012-03-03 Glenn Morris <rgm@gnu.org>
11114 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11116 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11119 position past the first glyph_row that ends at ZV. (Bug#10902)
11120 (redisplay_window, next_element_from_string): Fix typos in
11122 (redisplay_window): Pass to move_it_vertically the margin in

11127 * buffer.c (buffer-list-update-hook): Doc fix.
11129 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11131 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11132 push_it before setting up the iterator for the first overlay
11133 string, even if we have an empty string loaded.
11134 (next_overlay_string): If there's an empty string on the iterator
11135 stack, pop the stack. (Bug#10903)
11137 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11139 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11140 Suggested by Stefan Monnier in
11141 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11142 * alloc.c (widen_to_Lisp_Object): New static function.
11143 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11144 and widening them to Lisp_Objects. This would work even if
11145 USE_LSB_TAG is defined and wide integers are used, which might
11146 happen in a future version of Emacs.
11148 2012-02-25 Chong Yidong <cyd@gnu.org>
11150 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

11159 * keyboard.c (process_special_events): Handle all X selection
11160 requests in kbd_buffer, not just the next one (Bug#8869).
11162 2012-02-23 Chong Yidong <cyd@gnu.org>
11164 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11165 call when setting menu-bar-lines and tool-bar-lines parameters.
11166 (unwind_create_frame_1): New helper function.
11168 * window.c (inhibit_window_configuration_change_hook): New var.

11187 when computing $valmask.
11189 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11190 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11191 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11192 It's useless in that case, and it can cause problems on hosts
11193 that allocate halves of EMACS_INT values separately.
11194 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11195 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11196 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11197 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11198 it avoids undefined behavior on hosts where shifting right by more
11199 than the word width has undefined behavior.
11201 2012-02-19 Chong Yidong <cyd@gnu.org>
11203 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11204 (Funhandled_file_name_directory, Ffile_name_as_directory)

11223 2012-02-15 Chong Yidong <cyd@gnu.org>
11225 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

11241 2012-02-12 Chong Yidong <cyd@gnu.org>
11243 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11244 as that creates a dangerous corner case.
11246 * window.c (Fdelete_window_internal): Invalidate the mouse
11247 highlight (Bug#9904).
11249 2012-02-12 Glenn Morris <rgm@gnu.org>

11279 2012-02-07 Chong Yidong <cyd@gnu.org>
11281 * buffer.c (Fbuffer_local_variables)
11282 (buffer_lisp_local_variables): Handle unbound vars correctly;
11283 don't let Qunbound leak into Lisp.
11285 2012-02-07 Glenn Morris <rgm@gnu.org>
11287 * image.c (Fimagemagick_types): Doc fix.
11289 * image.c (imagemagick-render-type): Change it from a lisp object
11290 to an integer. Move the doc here from the lisp manual.

11320 before BEGV. (Bug#10696)
11322 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11324 Handle overflow when computing char display width (Bug#9496).
11325 * character.c (char_width): Return EMACS_INT, not int.
11326 (char_width, c_string_width): Check for overflow when
11327 computing the width; this is possible now that individual
11328 characters can have unbounded width. Problem introduced

11360 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11361 first 2 arguments are identical. This makes inserting large
11362 output from a subprocess an order of magnitude faster on
11363 MS-Windows, where all sbrk'ed memory is always contiguous.

11463 DISP_STRING, and accept any glyph in a row whose object is that
11464 string as eligible for mouse highlight. Fixes mouse highlight of
11465 display strings from overlays. (Bug#10464)
11467 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>

11982 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
11983 is set, removing the need for VIRT_ADDRESS_VARIES.
11984 (PURE_P): Use a more-efficient implementation that needs just one

11999 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12000 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12001 behave as if the cursor position were at the window margin.
12003 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12004 and the cursor position is out of bounds, behave as if the cursor
12005 position were at the window margin. (Bug#10075)
12007 2011-11-18 Chong Yidong <cyd@gnu.org>
12009 * window.c (Fwindow_combination_limit): Make first argument

12031 compute_line_metrics.
12032 (compute_line_metrics): Call row_hash, instead of computing the
12035 * dispnew.c (verify_row_hash): Call row_hash for computing the
12036 hash code of a row, instead of duplicating code from xdisp.c.
12038 * dispextern.h (row_hash): Add prototype.
12040 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12042 * frame.c (delete_frame): Don't delete the terminal when the last

12225 Otherwise, these inline functions do not conform to C99 and
12226 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12227 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12228 * intervals.c (adjust_intervals_for_insertion)

12231 (static_offset_intervals): Remove.
12232 (offset_intervals): Rewrite using the old contents of
12233 static_offset_intervals. The old version didn't conform to C99
12234 because an extern inline function contained a reference to an
12235 identifier with static linkage.

12500 (Fgnutls_deinit, Fgnutls_boot): Use it.
12502 * process.c (make_process): Initialize GnuTLS credentials to NULL.
12503 (deactivate_process): Call emacs_gnutls_deinit.
12505 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12507 * image.c (x_create_x_image_and_pixmap):
12508 * w32.c (sys_rename, w32_delayed_load):
12509 * w32font.c (fill_in_logfont):
12510 * w32reg.c (x_get_string_resource): Silence compiler warnings.
12512 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
12514 * w32fns.c (w32_default_color_map): New function,
12515 extracted from Fw32_default_color_map.
12516 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
12518 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
12520 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
12522 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
12524 * keyboard.c (test_undefined): New function (bug#9751).
12525 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
12527 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
12529 * sysdep.c (init_sys_modes): Fix the check for the controlling
12530 terminal (Bug#6649).
12532 2011-10-20 Eli Zaretskii <eliz@gnu.org>
12534 * dispextern.h (struct bidi_it): New member next_en_type.
12536 * bidi.c (bidi_line_init): Initialize the next_en_type member.
12537 (bidi_resolve_explicit_1): When next_en_pos is valid for the
12538 current character, check also for next_en_type being WEAK_EN.
12539 (bidi_resolve_weak): Don't enter the expensive loop if the current
12540 position is before next_en_pos. Record the bidi type of the first
12541 non-ET, non-BN character we find, in addition to its position.
12542 (bidi_level_of_next_char): Invalidate next_en_type when
12543 next_en_pos is over-stepped.
12545 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
12547 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12548 * editfns.c: Rewrite current-time-zone so that it invokes
12549 the equivalent of (format-time-string "%Z") to get the time zone name.
12550 This fixes a bug when the time zone name contains characters that
12551 need converting from the system time locale to Emacs internal format.
12552 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12553 that patch fixed format-time-string to do the conversion, but
12554 I forgot to fix current-time-zone.
12555 (format_time_string): New function, containing most of
12556 what Fformat_time_string used to contain.
12557 (Fformat_time_string): Rewrite in terms of format_time_string.
12558 This doesn't change this function's behavior.
12559 (current-time-zone): Rewrite to use format_time_string.
12560 This fixes the bug reported by Michael Schierl in
12561 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12562 Jason Rumney's 2007-06-07 change worked around this bug, but
12564 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12566 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12568 * xdisp.c (start_display): If the character at POS is displayed
12569 via a display vector, reset IT->current.dpvec_index to zero.
12570 (try_window_reusing_current_matrix): If a line ends in a display
12571 vector or the next line starts in a display vector, continue
12572 redrawing the window even though the character position of
12573 start_row was reached.
12576 2011-10-18 Chong Yidong <cyd@gnu.org>
12578 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12579 with nobreak-char-display too.
12581 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12583 Fix part 3 of bug#9771.
12584 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12585 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12586 non-neutral characters if the current character is a paragraph
12587 separator (a.k.a. Newline). This avoids running the same
12588 expensive loop twice, once when we consume the preceding newline
12589 and the other time when the line actually needs to be displayed.
12590 Avoid the loop when we see neutrals on the base embedding level
12591 following a character whose directionality is the same as the
12592 paragraph's. This avoids running the expensive loop when a line
12593 ends in a long sequence of neutrals, like control characters.
12594 Add assertion against STRONG_AL type. Slightly rearrange code
12595 that determines the type of a neutral given the first non-neutral
12597 (bidi_level_of_next_char): Set next_en_pos to zero when
12598 invalidating its info.
12600 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12602 * xdisp.c (push_display_prop): Determine whether to record string
12603 or buffer position by IT->string, not by IT->method. Allow
12604 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12605 (move_it_vertically_backward): Don't look for character position
12606 immediately after the newline when in a continuation line.
12609 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12611 * window.c (coordinates_in_window): Rewrite and delabelize
12612 vertical border check. (Bug#5357) (Bug#9618)
12614 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12616 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12617 errors in XSetWindowBorder (bug#9310).
12619 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12621 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12622 avoid crash when xmalloc overrun checking is enabled.
12624 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12626 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12627 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12628 cursor motion with <left> and <right> arrow keys.
12630 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12631 some callers set that themselves.
12633 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12635 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12636 display string and the previous row comes from the same string and
12637 is empty. (Bug#9739) (Bug#9738)
12639 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12641 * doc.c (get_doc_string): Encode file name (bug#9735).
12643 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12645 * bidi.c (bidi_level_of_next_char):
12646 * xdisp.c (get_visually_first_element): Remove old incorrect
12647 comments regarding the Unicode Line Separator character.
12649 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12651 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12653 * alloc.c (Fgc_status): Do not access beyond zombies array
12654 boundary if nzombies > MAX_ZOMBIES.
12655 * alloc.c (dump_zombies): Add missing format specifier.
12657 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12659 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12660 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12662 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12663 Some packages use them to denote characters with modifiers.
12665 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12667 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12668 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12669 matching a pp-number. Rename parameter var to var1.
12671 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12673 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12675 2011-10-08 Glenn Morris <rgm@gnu.org>
12677 * callint.c (Fcall_interactively): Give a more explicit error for the
12678 'c' case with a non-character input. (Bug#8479)
12680 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12682 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12684 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12685 lines that are hscrolled on the left.
12687 * dispnew.c (buffer_posn_from_coords): Account for a possible
12688 presence of header-line. (Bug#4426)
12690 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12692 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12693 Don't advertise functionality which we discourage or doesn't work.
12695 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12697 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12698 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12699 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12700 this makes Emacs dump core during garbage collection on rare
12701 occasions. sizeof is obviously inferior to offsetof here, so
12702 stick with offsetof.
12703 (GC_POINTER_ALIGNMENT): New macro.
12704 (mark_memory): Omit 3rd (offset) arg; caller changed.
12705 Don't assume EMACS_INT alignment is the same as pointer alignment.
12707 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12709 * keyboard.c (read_key_sequence_remapped): New var.
12710 (read_key_sequence): Compute remapping in the right buffer.
12711 (command_loop_1): Use read_key_sequence's remapping directly.
12713 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12715 * dired.c (file_name_completion): Don't expand file name.
12716 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12717 before checking file name handler.
12719 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12720 they've been requested explicitly (bug#9591).
12722 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12724 * keymap.c (Fsingle_key_description): Use make_specified_string
12725 instead of build_string to build string from push_key_description.
12728 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12730 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12731 This fixes a Y2038 bug on 64-bit hosts.
12732 * buffer.c (reset_buffer):
12733 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12734 (Fclear_buffer_auto_save_failure):
12735 Use 0, not -1, to represent an unset failure time, since time_t
12736 might not be signed.
12738 Remove dependency on glibc malloc internals.
12739 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12740 Move back here from lisp.h, but with their new implementations.
12741 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12742 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12743 * charset.c (charset_table_init): New static var.
12744 (syms_of_charset): Use it instead of xmalloc. This removes a
12745 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12746 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12747 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12748 Move back to alloc.c.
12749 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12750 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12752 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12754 * nsterm.m (windowDidResize): Call x_set_window_size only when
12755 ns_in_resize is true. Otherwise set pixelwidth/height and
12756 call change_frame_size (Bug#9628).
12758 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12760 Port --enable-checking=all to Fedora 14 x86-64.
12761 * charset.c (syms_of_charset): Also account for glibc malloc's
12762 internal overhead when calculating the initial malloc maximum.
12764 Port --enable-checking=all to Fedora 14 x86.
12765 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12767 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12768 (overrun_check_realloc, overrun_check_free):
12769 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12770 That way, xmalloc returns a properly-aligned pointer even if
12771 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12772 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12773 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12774 into account when calculating the initial malloc maximum.
12775 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12776 Move here from alloc.c, so that charset.c can use it too.
12777 Properly align; the old code wasn't right for common 32-bit hosts
12778 when configured with --enable-checking=all.
12779 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12780 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12782 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12784 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12787 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12789 * xdisp.c (compute_display_string_end): If there's no display
12790 string at CHARPOS, return -1.
12792 * bidi.c (bidi_fetch_char): When compute_display_string_end
12793 returns a negative value, treat the character as a normal
12794 character not covered by a display string. (Bug#9624)
12796 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12798 * lread.c (Fread_from_string): Fix typo in docstring.
12800 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12802 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12803 newline, reseat the iterator instead of bidi-iterating there one
12804 character at a time. (Bug#9610)
12805 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12806 TO_CHARPOS if the bidi iterator is at base embedding level.
12808 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12810 * lread.c (readevalloop): Use correct code for NBSP.
12811 (read1): Likewise. (Bug#9608)
12813 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12815 * dbusbind.c (Fdbus_register_signal): When service is not
12816 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12818 2011-09-25 Glenn Morris <rgm@gnu.org>
12820 * buffer.c (truncate-lines): Doc fix.
12822 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12824 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12825 (Fset_window_next_buffers): Doc fix.
12827 2011-09-24 Glenn Morris <rgm@gnu.org>
12829 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12831 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12833 Fix minor problems found by static checking.
12834 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12835 * indent.c (Fvertical_motion): Fix == vs = typo.
12837 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12839 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12840 Default value is now t. Doc fix.
12842 * indent.c (Fvertical_motion): Compute and apply the overshoot
12843 logic when moving up, not only when moving down. Fix the
12844 confusing name and values of the it_overshoot_expected variable;
12845 logic changes accordingly. (Bug#9254) (Bug#9549)
12847 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12848 CHARPOS is covered by a display string which includes newlines.
12849 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12850 is covered by a display string with embedded newlines.
12852 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12854 * dbusbind.c (Fdbus_register_signal): Add match rule to
12855 Vdbus_registered_objects_table. (Bug#9581)
12856 (Fdbus_register_method, Vdbus_registered_objects_table):
12859 2011-09-24 Jim Meyering <meyering@redhat.com>
12861 do not ignore write error for any output size
12862 The previous change was incomplete.
12863 While it makes emacs --batch detect the vast majority of stdout
12864 write failures, errors were still ignored whenever the output size is
12865 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12866 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12867 && echo FAIL: ignored write error
12868 FAIL: ignored write error
12869 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12870 && echo FAIL: ignored write error
12871 FAIL: ignored write error
12872 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12874 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12876 * emacs.c (Fkill_emacs): In noninteractive mode exit
12877 non-successfully if a write error occurred on stdout. (Bug#9574)
12879 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12881 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12884 * dispextern.h (struct it): Update the comment documenting what
12887 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12889 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12890 a display string, extend search for cursor position to end of row.
12891 (find_row_edges): If the row ends in a newline from a display
12892 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12893 Handle the case of a display string with multiple newlines.
12894 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12895 non-empty line. Fixes confusing cursor motion with arrow keys at
12896 the beginning of a line that starts with whitespace.
12898 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12900 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12903 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12905 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12906 boolean (Bug#9154).
12908 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12910 * xdisp.c (display_line): Record maximum and minimum buffer
12911 positions even if no glyphs were produced (e.g., by a zero-width
12912 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12913 buffer positions that will be removed from the glyph row because
12915 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12916 column is beyond frame width: don't subtract 1 "pixel" when
12917 computing width of the stretch.
12918 (reseat_at_next_visible_line_start): Undo the change made on
12919 2011-09-17 that saved paragraph information and restored it after
12920 the call to `reseat'. (Bug#9545)
12922 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12924 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12925 and turn window cursor on if cleared (Bug#9415).
12927 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12929 * search.c (boyer_moore): Take unibyte characters from pattern
12930 literally. (Bug#9458)
12932 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12934 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12936 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12938 Fix minor problem found by static checking.
12939 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12940 initialized, to pacify gcc -Wuninitialized.
12942 * fileio.c: Report proper errno when syscall falls.
12943 (Finsert_file_contents): Save and restore errno,
12944 so that report_file_error outputs the correct diagnostic.
12945 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12947 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12949 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12951 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12953 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12954 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12956 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12958 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12959 about the current paragraph and restore it after the call to reseat.
12961 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12962 (bidi_find_paragraph_start): Search back for paragraph beginning
12963 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12964 (bidi_move_to_visually_next): Only trigger paragraph-related
12965 computations when the last character is a newline or at EOB, not
12966 just any NEUTRAL_B. (Bug#9470)
12968 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12969 truncated lines if point is covered by a display string. (Bug#9524)
12971 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12973 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12974 (cons_to_x_long): New function.
12975 (lisp_data_to_selection_data): Use it. Correct the test for
12976 short-versus-long data; it was negated. Break out of vector
12977 loop, for efficiency, when a long datum is discovered.
12979 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12981 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12983 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12985 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12986 GCC PR/17406) by declaring this function with external scope.
12988 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12990 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12991 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12993 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12995 * editfns.c (Fformat): Correctly handle text properties on "%%".
12997 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12999 * xterm.c (x_draw_composite_glyph_string_foreground):
13000 * w32term.c (x_draw_composite_glyph_string_foreground):
13001 * term.c (encode_terminal_code):
13002 * composite.c (composition_update_it, get_composition_id):
13003 * xdisp.c (get_next_display_element)
13004 (fill_composite_glyph_string): Add comments about special meaning
13005 of TAB characters in a composition.
13007 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13009 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13010 This occurs when processing a multibyte format.
13011 Problem reported by Wolfgang Jenker.
13013 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13015 * xdisp.c (try_cursor_movement): Only check for exact match if
13016 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13018 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13020 Remove unused external symbols.
13021 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13022 * xdisp.c (calc_pixel_width_or_height): Now static.
13023 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13024 * indent.c (check_display_width):
13025 * w32term.c: Fix comment to match code.
13026 * xterm.c, xterm.h (x_catching_errors): Remove.
13028 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13030 * xselect.c: Use signed conversions more consistently (Bug#9498).
13031 (selection_data_to_lisp_data): Assume incoming selection data are
13032 signed integers, not unsigned. This is to be consistent with
13033 outgoing selection data, which was modified to use signed integers
13034 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13035 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13036 expects long, not unsigned long.
13038 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13040 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13041 computation of loop end. Reported by Johan Bockgård
13044 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13046 * frame.c (Fother_visible_frames_p): Function deleted.
13048 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13050 * indent.c (compute_motion): Process display vector front to back
13051 rather than the other way around. (Bug#2496)
13053 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13055 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13057 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13059 * minibuf.c (Fread_from_minibuffer): Doc fix.
13061 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13063 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13064 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13066 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13068 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13069 value for non-existent files.
13071 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13073 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13074 set its "size" to -1. This will set the modtime_size field of
13075 the corresponding buffer to -1, which is what
13076 verify-visited-file-modtime expects for files that do not exist.
13079 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13081 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13083 * lisp.h: ... from here. push_key_description is no longer
13084 defined in keyboard.c, so its declaration should not be in
13085 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13086 logically belongs with push_key_description.
13088 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13090 * buffer.h: Include <sys/types.h> instead of <time.h>.
13091 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13092 Problem reported by Herbert J. Skuhra.
13094 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13096 * xml.c (parse_region): Make the parsing work for
13097 non-comment-starting XML files again (bug#9144).
13099 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13101 * image.c (gif_load): Fix calculation of bottom and right corner.
13104 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13106 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13107 redisplay in small windows.
13109 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13111 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13113 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13115 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13116 Operate on live windows only.
13118 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13120 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13122 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13124 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13125 only under bidi iteration.
13127 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13129 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13131 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13133 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13134 Without this fix, the command to link temacs failed due to an
13135 undefined symbol __builtin_isnan. This is because
13136 /usr/include/iso/math_c99.h #defines isnan(x) to
13137 __builtin_isnan(x), but the bundled gcc, which identifies itself
13138 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13140 * floatfns.c (isnan): #undef, and then #define to a clone of
13142 (Fisnan): Always define, since it's always available now.
13143 (syms_of_floatfns): Always define isnan at the Lisp level.
13145 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13147 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13149 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13151 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13152 The previous code assumed that file offsets (off_t values) fit in
13153 EMACS_INT variables, which is not true on typical 32-bit hosts.
13154 The code messed up by falsely reporting buffer overflow in cases
13155 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13156 when "big" contains more than 2**29 bytes, even though this
13157 inserts just one byte and does not overflow the buffer.
13158 (Finsert_file_contents): Store file offsets as off_t
13159 values, not as EMACS_INT values. Check for overflow when
13160 converting between EMACS_INT and off_t. When checking for
13161 buffer overflow or for overlap, take the offsets into account.
13162 Don't use EMACS_INT for small values where int suffices.
13163 When checking for overlap, fix a typo: ZV was used where
13164 ZV_BYTE was intended.
13165 (Fwrite_region): Don't assume off_t fits into 'long'.
13166 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13168 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13170 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13172 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13174 sprintf-related integer and memory overflow issues (Bug#9412).
13176 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13177 (esprintf, exprintf, evxprintf): New functions.
13178 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13179 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13180 (modify_event_symbol): Do not assume that the length of
13181 name_alist_or_stem is safe to alloca and fits in int.
13182 (Fexecute_extended_command): Likewise for function name and binding.
13183 (Frecursion_depth): Wrap around reliably on integer overflow.
13184 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13185 since some callers pass EMACS_INT values.
13186 (Fsingle_key_description): Don't crash if symbol name contains more
13187 than MAX_ALLOCA bytes.
13188 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13189 (get_minibuffer): Arg is now EMACS_INT, not int.
13190 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13191 (esprintf, exprintf, evxprintf): New decls.
13192 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13194 * dbusbind.c (signature_cat): New function.
13195 (xd_signature, Fdbus_register_signal):
13196 Do not overrun buffer; instead, report string overflow.
13198 * dispnew.c (add_window_display_history): Don't overrun buffer.
13199 Truncate instead; this is OK since it's just a log.
13201 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13202 even if the time zone offset is outlandishly large.
13203 Don't mishandle offset == INT_MIN.
13205 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13206 when creating daemon; the previous buffer-overflow check was incorrect.
13208 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13209 which has the guts of the old verror function.
13211 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13212 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13214 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13215 (font_unparse_xlfd): Don't blindly alloca long strings.
13216 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13217 fits in int, when using sprintf. Use single snprintf to count
13218 length of string rather than counting it via multiple sprintfs;
13219 that's simpler and more reliable.
13220 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13221 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13222 sprintf, in case result does not fit in int.
13224 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13225 (fontset_from_font): Print it.
13227 * frame.c (tty_frame_count): Now printmax_t, not int.
13228 (make_terminal_frame, set_term_frame_name): Print it.
13229 (x_report_frame_params): In X, window IDs are unsigned long,
13230 not signed long, so print them as unsigned.
13231 (validate_x_resource_name): Check for implausibly long names,
13232 and don't assume name length fits in 'int'.
13233 (x_get_resource_string): Don't blindly alloca invocation name;
13234 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13237 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13238 (xg_check_special_colors, xg_set_geometry):
13239 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13241 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13242 Use esprintf, not sprintf, in case result does not fit in int.
13244 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13245 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13246 it as a large positive number.
13247 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13248 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13250 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13251 in case result does not fit in int.
13253 * print.c (float_to_string): Detect width overflow more reliably.
13254 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13255 buffer overrun. Don't assume list length fits in 'int'. Treat
13256 print length of 0 as 0, not as infinity; to be consistent with other
13257 uses of print length in this function. Don't overflow print length
13258 index. Don't assume hash table size fits in 'long', or that
13259 vectorlike size fits in 'unsigned long'.
13261 * process.c (make_process): Use printmax_t, not int, to format
13262 process-name gensyms.
13264 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13266 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13267 to avoid potential buffer overrun.
13269 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13270 if X resource line is longer than 512 bytes.
13272 * xfns.c (x_window): Make sprintf buffer a bit bigger
13273 to avoid potential buffer overrun.
13275 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13277 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13279 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13281 Integer overflow fixes for scrolling, etc.
13282 Without these, Emacs silently mishandles large integers sometimes.
13283 For example, "C-u 4294967297 M-x recenter" was treated as if
13284 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13286 * xdisp.c (try_window_id): Check Emacs fixnum range before
13287 converting to 'int'.
13289 * window.c (window_scroll_line_based, Frecenter):
13290 Check that an Emacs fixnum is in range before assigning it to 'int'.
13291 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13292 values converted from Emacs fixnums.
13293 (Frecenter): Don't wrap around a line count if it is out of 'int'
13294 range; instead, treat it as an extreme value.
13295 (Fset_window_configuration, compare_window_configurations):
13296 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13298 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13299 that can exceed INT_MAX. Check that EMACS_INT value is in range
13300 before assigning it to the (possibly-narrower) index.
13301 (match_limit): Don't assume that a fixnum can fit in 'int'.
13303 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13306 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13307 (Fvertical_motion): Don't wrap around LINES values that don't fit
13308 in 'int'. Instead, treat them as extreme values. This is good
13309 enough for windows, which can't have more than INT_MAX lines anyway.
13311 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13313 * Require libxml/parser.h to avoid compilation warning.
13315 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13317 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13318 since this reportedly can destroy thread storage.
13320 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13322 * syntax.c (find_defun_start): Update all cache variables if
13323 exiting early (Bug#9401).
13325 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13327 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13329 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13330 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13331 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13333 * term.c (tty_append_glyph): New function.
13334 (produce_stretch_glyph): Static function and its prototype deleted.
13336 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13339 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13341 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13342 when checking :margin (Bug#9390).
13343 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13344 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13345 so that the name doesn't mislead. All uses changed.
13347 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13349 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13352 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13354 * xdisp.c (move_it_to): Don't bail out early when reaching
13355 position beyond to_charpos, if we are scanning backwards.
13356 (move_it_vertically_backward): When DY == 0, make sure we get to
13357 the first character in the line after the newline.
13359 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13361 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13362 (ccl_driver): Do not generate an out-of-range pointer.
13363 (Fccl_execute_on_string): Remove unnecessary check for
13364 integer overflow, noted by Stefan Monnier in
13365 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13366 Remove a FIXME that didn't need fixing.
13367 Simplify the newly-introduced buffer reallocation code.
13369 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13371 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13373 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13375 Integer and memory overflow issues (Bug#9196).
13377 * doc.c (get_doc_string): Rework so that
13378 get_doc_string_buffer_size is the actual buffer size, rather than
13379 being 1 less than the actual buffer size; this makes xpalloc more
13382 * image.c (x_allocate_bitmap_record, cache_image):
13383 * xselect.c (Fx_register_dnd_atom):
13384 Simplify previous changes by using xpalloc.
13386 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13387 since either will do and ptrdiff_t is convenient with xpalloc.
13389 * charset.c (charset_table_size)
13390 (struct charset_sort_data.priority): Now ptrdiff_t.
13391 (charset_compare): Don't overflow if priorities differ greatly.
13392 (Fsort_charsets): Don't assume list length fits in int.
13393 Check for size-calculation overflow when allocating sort data.
13394 (syms_of_charset): Allocate an initial charset table that is
13395 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13397 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13399 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13400 The actual value is always <= INT_MAX, and leaving it unsigned made
13401 overflow checking harder.
13403 * dispextern.h (struct glyph_matrix.rows_allocated)
13404 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13405 with xpalloc. The values are still always <= INT_MAX.

13415 (revalidate_region_cache, know_region_cache, region_cache_forward)
13416 (region_cache_backward, pp_cache):
13417 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13418 so that ptrdiff_t * can be passed to xpalloc.

13420 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

13435 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13437 Don't update size of array until after memory allocation succeeds,
13438 because xmalloc/xrealloc may not return.
13439 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13440 now that we have proper integer overflow checking.
13441 (record_overlay_string, overlay_strings): Catch overflows when
13442 calculating size of overlay_str_buf.
13444 * callproc.c (Fcall_process): Check for size overflow when
13445 calculating size of args2.
13446 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.

13448 require adding more-complicated checks.
13450 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13451 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

13491 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13493 * emacs.c (main): Do not reallocate argv, since there is a null at
13494 the end that can be overwritten, and this way there's no need to
13495 worry about size-calculation overflow.
13496 (sort_args): Check for size-calculation overflow.
13498 * eval.c (init_eval_once, grow_specpdl): Don't update size until

13504 Check for integer overflow.
13505 (x_set_alpha): Do not assume XINT fits in int.
13507 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13508 This is for the members text_lines, text_cols, total_lines, total_cols,
13509 where the system imposes an 'int' limit.
13511 * fringe.c (Fdefine_fringe_bitmap):
13512 Don't update size until alloc works.

13517 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
13518 Check for size-calculation overflow.
13519 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13520 do, as we prefer signed integers.
13521 (id_to_widget.max_size, id_to_widget.used)
13522 (xg_store_widget_in_map, xg_remove_widget_from_map)

13527 * gtkutil.h: Change prototypes to match the above.
13529 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

13576 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13577 for command line length. Do not attempt to address one before the
13578 beginning of an array, as that's not portable.

13625 (X_LONG_MIN): New macros.
13626 Use them to make the following changes clearer.
13627 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

13629 future maintainers not to raise the value too much later.
13630 (SELECTION_QUANTUM): Remove, replacing with ...
13631 (selection_quantum): ... new function, which avoids overflow.
13633 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13634 assumption that selection length fits in 'int'.

13651 Don't store size until memory allocation succeeds.
13652 (x_get_window_property): Plug memory leak on memory exhaustion.
13653 Don't double-block input; malloc is safe here. Don't assume 2**34
13654 - 4 fits in unsigned long. Add an xassert to check
13655 XGetWindowProperty overflow. Be more careful about overflow
13656 calculations, and distinguish size from memory overflow better.
13657 (receive_incremental_selection): When tracing, don't assume
13658 unsigned int is less than INT_MAX.
13659 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

13662 in the range -65535 through -1 fit in an X unsigned short.
13663 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13664 result parameters unless successful. Rely on cons_to_unsigned
13665 to report problems with elements; the old code wasn't right anyway.
13666 (x_check_property_data): Check for int overflow; we cannot use
13667 a wider type due to X limits.

13700 * lisp.h (hash_lookup, hash_put):
13701 * minibuf.c (Ftest_completion):
13702 Use ptrdiff_t for hash table indexes, not int (which is too
13703 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

13706 * charset.c (Fdefine_charset_internal): Check for integer overflow.
13707 Add a FIXME comment about memory leaks.

13715 with outlandish widths.
13716 * character.h (sanitize_tab_width): Rename from sanitize_width,

13742 (make_lispy_movement): Use same integer type in forward decl
13743 that is used in the definition.

13745 Change bufsize argument back to int, undoing my 2011-03-30 change.
13746 We prefer signed types, and int is wide enough here.
13747 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13748 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13749 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13750 length, not size_t. Use ptrdiff_t for index, not int.
13751 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13752 possibility of integer overflow.

13780 Prefer int to unsigned where either will do.
13781 (tiff_handler): New function, combining the cores of the
13782 old tiff_error_handler and tiff_warning_handler.
13783 This function is rewritten to use vsnprintf and thereby avoid
13784 stack buffer overflows. It uses only the features of vsnprintf
13785 that are common to both POSIX and native Microsoft.
13786 (tiff_error_handler, tiff_warning_handler): Use it.
13787 (tiff_load, gif_load, imagemagick_load_image):
13788 Don't assume :index value fits in 'int'.

13830 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
13831 buffers, return left-to-right.
13832 (set_cursor_from_row): Consider candidate row a win if its glyph
13833 represents a newline and point is on that newline. Fixes cursor
13834 positioning on the newline at EOL of R2L text within L2R
13835 paragraph, and vice versa.
13836 (try_cursor_movement): Check continued rows, in addition to
13837 continuation rows. Fixes unwarranted scroll when point enters a
13838 continued line of R2L text within an L2R paragraph, or vice versa.
13839 (cursor_row_p): Consider the case of point being equal to
13840 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13841 from the end of a short line to the beginning of a continued line
13842 of R2L text within L2R paragraph.
13843 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
13844 composed characters.

13859 2011-08-22 Kenichi Handa <handa@m17n.org>
13861 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
13862 extra slot even if the purpose is char-code-property-table.
13864 2011-08-23 Eli Zaretskii <eliz@gnu.org>
13866 * xdisp.c (redisplay_window): When computing centering_position,
13867 account for the height of the header line. (Bug#8874)
13869 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13870 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13871 candidate is selected by the mouse, and that candidate has a
13872 composed character under the mouse.
13874 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13875 coordinates reported by pos-visible-in-window-p for a composed
13876 character in column zero.
13878 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
13880 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
13882 2011-08-22 Eli Zaretskii <eliz@gnu.org>
13884 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
13885 consider it a hit if to_charpos is anywhere in the range of the
13886 composed buffer positions.
13888 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13890 * image.c (gif_load): Don't assume that each subimage has the same
13891 dimensions as the base image. Handle disposal method that is
13892 "undefined" by the gif spec (Bug#9335).
13894 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13896 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
13897 (Fcondition_case): Document `debug' symbol in error handler.
13899 2011-08-19 Eli Zaretskii <eliz@gnu.org>
13901 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
13902 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13903 from an Org mode buffer to a Speedbar frame.
13905 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13906 a composition, take its buffer position from IT->cmp_it.charpos.
13907 Fixes cursor positioning at the beginning of a line that begins
13908 with a composed character.
13910 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13912 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13913 character bidirectional type, use STRONG_L instead. Fixes crashes
13914 in a buffer produced by `describe-categories'.
13916 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13917 members before the level stack, so they would be saved and
13918 restored when copying iterator state. Fixes incorrect reordering
13919 around TABs covered by display properties.
13921 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
13923 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
13925 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
13927 * eval.c (internal_condition_case, internal_condition_case_1)
13928 (internal_condition_case_2, internal_condition_case_n):
13929 Remove unnecessary aborts (Bug#9081).
13931 2011-08-17 Eli Zaretskii <eliz@gnu.org>
13933 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
13934 has no `load' handler, try opening the file locally. (Bug#9311)
13936 2011-08-16 Ken Brown <kbrown@cornell.edu>
13938 * gmalloc.c: Expand comment.
13940 2011-08-16 Eli Zaretskii <eliz@gnu.org>

13988 * process.c (create_process): Call setup_process_coding_systems
13989 after the pid of the process is set to -1 (Bug#8162).
13991 2011-08-14 Eli Zaretskii <eliz@gnu.org>
13993 * xdisp.c (move_it_in_display_line_to): Don't invoke
13994 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13995 ppos_it. Fixes vertical cursor motion when line beginning is
13996 covered by an image. (Bug#9296)
13998 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14000 * nsterm.h (ns_run_ascript): Declare.

14004 (ns_run_ascript): New function.
14005 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14006 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14007 the event loop. Get status from as_status (Bug#7276).
14009 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14010 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14011 the event loop (Bug#7276).
14013 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14015 * gnutls.c (QCgnutls_bootprop_priority)
14016 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
14017 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
14018 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
14019 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
14020 (QCgnutls_bootprop_verify_hostname_error)

14037 (Fnetwork_interface_list): Allocate in increments of bytes instead
14038 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14039 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14041 (struct ifflag_def): notrailers is smart on OSX.
14042 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14043 Get hardware address with getifaddrs if available.
14045 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14047 * xdisp.c (iterate_out_of_display_property): xassert that
14048 IT->position is set to within IT->object's boundaries. Break from
14049 the loop as soon as EOB is reached; avoids infloops in redisplay
14050 when IT->position is set up wrongly due to some bug.
14051 Set IT->current to match the bidi iterator unconditionally.
14052 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14053 entry. Force push_it to save on the stack the current
14054 buffer/string position, to be restored by pop_it. Fix flags in
14055 the iterator structure wrt the object coming from a display
14056 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14057 properties. (Bug#9284)
14059 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14061 * fontset.c (fontset_get_font_group): Add proper type checks.

14074 no-display-properties-and-no-overlays under bidi display.
14075 Set disp_pos in the bidi iterator to avoid searches for display
14076 properties and overlays.
14078 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14080 * editfns.c (Fset_time_zone_rule): Document relationship with the

14091 2011-08-07 Juri Linkov <juri@jurta.org>
14093 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14094 to show the arg `TIME' instead of `TIMEVAL'.
14096 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14098 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14099 display property strides EOL and includes a newline, as in
14100 longlines-mode. (Bug#9254)
14101 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14102 word-wrap under bidirectional display. (Bug#9224)
14104 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14105 is non-zero, even if the data buffer is NULL. Fixes a crash in
14106 vertical-motion with longlines-mode. (Bug#9254)
14108 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14110 * bidi.c <bidi_cache_total_alloc>: Now static.

14113 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14116 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14117 amount allocated this far in `bidi_cache_total_alloc'.
14118 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14119 non-zero, only free the data buffer without restoring the cache
14120 contents. All callers changed.
14122 * dispextern.h (bidi_unshelve_cache): Update prototype.
14124 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

14126 (move_it_vertically_backward, move_it_by_lines): Replace the call
14127 to xfree to an equivalent call to bidi_unshelve_cache.
14128 (move_it_in_display_line_to): Fix logic of returning
14129 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14131 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14133 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

14184 * bidi.c (bidi_fetch_char): Accept an additional argument
14185 DISP_PROP_P, and pass it to compute_display_string_pos.
14186 Only handle text covered by a display string if DISP_PROP_P is returned
14187 non-zero. All callers of bidi_fetch_char changed.
14189 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

14219 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14221 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14222 This is needed if max-image-size is a floating-point number.

14274 Without this fix, if a signal arrives just after memory fills up,
14275 'malloc' might be invoked reentrantly.
14277 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14278 In other words, assume that every image size is allowed, on non-X
14279 hosts. This assumption is probably wrong, but it lets Emacs compile.

14303 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14304 (bidi_find_other_level_edge):
14305 Use ptrdiff_t instead of EMACS_INT where either will do.
14306 This works better on 32-bit hosts configured --with-wide-int.
14307 (bidi_cache_ensure_space): Check for size-calculation overflow.
14308 Use % rather than repeated addition, for better worst-case speed.
14309 Don't set bidi_cache_size until after xrealloc returns, because it
14311 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14312 (bidi_cache_ensure_space): Also check that the bidi cache size
14313 does not exceed that of the largest Lisp string or buffer. See Eli
14314 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14316 * alloc.c (__malloc_size_t): Remove.
14317 All uses replaced by size_t. See Andreas Schwab's note
14318 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14320 * image.c: Improve checking for integer overflow.
14321 (check_image_size): Assume that f is nonnull, since
14322 it is always nonnull in practice. This is one less thing to
14323 worry about when checking for integer overflow later.
14324 (x_check_image_size): New function, which checks for integer
14325 overflow issues inside X.
14326 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14327 This removes the need for a memory_full check.
14328 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14329 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14330 (xbm_read_bitmap_data): Change locals back to 'int', since
14331 their values must fit in 'int'.
14332 (xpm_load_image, png_load, tiff_load):
14333 Invoke x_create_x_image_and_pixmap earlier,
14334 to avoid much needless work if the image is too large.
14335 (tiff_load): Treat overly large images as if
14336 x_create_x_image_and_pixmap failed, not as malloc failures.
14337 (gs_load): Use x_check_image_size.
14339 * gtkutil.c: Omit integer casts.
14340 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14341 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14343 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14345 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14346 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14347 would wrongly return t on a 64-bit host.
14349 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14350 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14351 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14352 and therefore cause GCC to emit a bogus diagnostic in some cases.
14354 * image.c: Integer signedness and overflow and related fixes.
14355 This is not an exhaustive set of fixes, but it's time to
14356 record what I've got.
14357 (lookup_pixel_color, check_image_size): Remove redundant decls.
14358 (check_image_size): Don't assume that arbitrary EMACS_INT values
14359 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14360 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14361 (tiff_load, imagemagick_load_image):
14362 Check for overflow in size calculations.
14363 (x_create_x_image_and_pixmap): Remove unnecessary test for
14364 xmalloc returning NULL; that can't happen.
14365 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14366 (xpm_color_bucket): Use better integer hashing function.
14367 (xpm_cache_color): Don't possibly over-allocate memory.
14368 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14369 (gif_memory_source):
14370 Use ptrdiff_t, not int or size_t, to record sizes.
14371 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14372 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14373 either works, as we prefer signed integers.
14374 (tiff_read_from_memory, tiff_write_from_memory):
14375 Return tsize_t, not size_t, since that's what the TIFF API wants.
14376 (tiff_read_from_memory): Don't fail simply because the read would
14377 go past EOF; instead, return a short read.
14378 (tiff_load): Omit no-longer-needed casts.
14379 (Fimagemagick_types): Don't assume size fits into 'int'.
14381 Improve hashing quality when configured --with-wide-int.
14382 * fns.c (hash_string): New function, taken from sxhash_string.
14383 Do not discard information about ASCII character case; this
14384 discarding is no longer needed.
14385 (sxhash-string): Use it. Change sig to match it. Caller changed.
14386 * lisp.h: Declare it.
14387 * lread.c (hash_string): Remove, since we now use fns.c's version.
14388 The fns.c version returns a wider integer if --with-wide-int is
14389 specified, so this should help the quality of the hashing a bit.
14391 * emacs.c: Integer overflow minor fix.
14392 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14393 Define only if GNU_LINUX.
14394 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14396 * dispnew.c: Integer signedness and overflow fixes.
14397 Remove unnecessary forward decls, that were a maintenance hassle.
14398 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14400 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14401 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14402 (prepare_desired_row, line_draw_cost):
14403 Use int, not unsigned, where either works.
14404 (save_current_matrix, restore_current_matrix):
14405 Use ptrdiff_t, not size_t, where either works.
14406 (init_display): Check for overflow more accurately, and without
14407 relying on undefined behavior.
14409 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14410 Remove, replacing with the new symbols in lisp.h. All uses changed.
14411 * fileio.c (make_temp_name):
14412 * filelock.c (lock_file_1, lock_file):
14413 * xdisp.c (message_dolog):
14414 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14415 Use pMd etc. instead.
14416 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14417 replacing the pWIDE etc. symbols removed from editfns.c.
14419 * keyboard.h (num_input_events): Now uintmax_t.
14420 This is (very slightly) less likely to mess up due to wraparound.
14423 * buffer.c: Integer signedness fixes.
14424 (alloc_buffer_text, enlarge_buffer_text):
14425 Use ptrdiff_t rather than size_t when either will do, as we prefer
14428 * alloc.c: Integer signedness and overflow fixes.
14429 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14430 (__malloc_size_t): Default to size_t, not to int.
14431 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14432 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14433 Prefer ptrdiff_t to size_t when either would do, as we prefer
14435 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14436 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14437 Now const. Initialize with values that are in range even if char
14439 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14440 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14441 These functions do the right thing with sizes > 2**32.
14442 (check_depth): Now ptrdiff_t, not int.
14443 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14444 Adjust to new way of storing sizes. Check for size overflow bugs
14446 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14447 slightly wrong anyway, as it missed one instance of
14448 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14449 (refill_memory_reserve): Omit needless cast to size_t.
14450 (mark_object_loop_halt): Mark as externally visible.
14452 * xselect.c: Integer signedness and overflow fixes.
14453 (Fx_register_dnd_atom, x_handle_dnd_message):
14454 Use ptrdiff_t, not size_t, since we prefer signed.
14455 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14456 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14457 x_dnd_atoms_size and x_dnd_atoms_length.
14459 * doprnt.c: Prefer signed to unsigned when either works.
14461 * doprnt.c (doprnt):
14463 * xdisp.c (vmessage):
14464 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14465 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14466 prefer signed arithmetic to avoid comparison confusion.
14467 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14468 but is a bit tricky.
14470 Assume freestanding C89 headers, string.h, stdlib.h.
14471 * data.c, doprnt.c, floatfns.c, print.c:
14472 Include float.h unconditionally.
14473 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14474 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14475 * regex.c: Likewise for stddef.h, string.h.
14476 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14477 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14478 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14479 (STDC_HEADERS): Remove obsolete defines.
14480 * sysdep.c: Include limits.h unconditionally.
14482 Assume support for memcmp, memcpy, memmove, memset.
14483 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14484 * regex.c (memcmp, memcpy):
14485 Remove; we assume C89 now.
14487 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14488 (__malloc_safe_bcopy): Remove; no longer needed.
14490 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14491 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14492 well either way, and we prefer signed to unsigned.
14494 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14496 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14497 closes the connection while we're reading (bug#9182).
14499 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14501 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14502 are specified (Bug#9168).
14504 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14506 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14507 Found by GCC static checking and --with-wide-int on a 32-bit host.
14509 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14511 * xdisp.c (compute_display_string_pos): Fix logic of caching
14512 previous display string position. Initialize cached_prev_pos to
14513 -1. Fixes slow-down at the beginning of a buffer.
14515 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14517 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14518 for attrs[LFACE_FONTSET_INDEX].
14520 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14522 * xml.c (parse_region): Remove unused local
14523 that was recently introduced.
14525 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14527 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14528 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14530 * xdisp.c (move_it_in_display_line_to): Record the best matching
14531 position for TO_CHARPOS while scanning the line, and restore it on
14532 exit if none of the characters scanned was an exact match.
14533 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14534 when exact match is impossible due to invisible text, and the
14535 lines are truncated.
14537 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14539 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14542 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14544 Fix a significant slow-down of cursor motion with C-n, C-p,
14545 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14546 auto-repeat under bidi redisplay in fontified buffers.
14547 * xdisp.c (compute_stop_pos_backwards): New function.
14548 (next_element_from_buffer): Call compute_stop_pos_backwards to
14549 find a suitable prev_stop when we find ourselves before
14551 (reseat): Don't look for prev_stop, as that could mean a very long
14553 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14554 <cached_disp_overlay_modiff>: Cache for last found display string
14556 (compute_display_string_pos): Return the cached position if asked
14557 about the same buffer in the same area of character positions, and
14558 the buffer wasn't changed since the time the display string
14559 position was cached.
14561 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14563 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14564 is an integer, which is important for empty lines. (Bug#9149)
14566 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14568 * frame.c (Fmodify_frame_parameters): In tty case, update the
14569 default face if necessary (Bug#4238).
14571 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14573 * editfns.c (Fstring_to_char): No need to explain what a character
14574 is in the docstring (Bug#6576).
14576 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14578 * xml.c (parse_region): Make sure we always return a tree.
14580 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14582 * xml.c (parse_region): If a document contains only comments,
14585 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14587 * xml.c (make_dom): Return comments, too.
14589 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14592 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14593 and the surrounding thread.
14594 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14595 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14596 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14598 * s/openbsd.h (BROKEN_SIGIO): Define.
14599 * unexelf.c (unexec) [__OpenBSD__]:
14600 Don't update the .mdebug section of the Alpha COFF symbol table.
14602 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14604 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14607 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14609 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14610 This fixes some race conditions on the permissions of any newly
14613 * alloc.c (valid_pointer_p): Use pipe, not open.
14614 This fixes some permissions issues when debugging.
14616 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14617 If fchown fails to set both uid and gid, try to set just gid,
14618 as that is sometimes allowed. Adjust the file's mode to eliminate
14619 setuid or setgid bits that are inappropriate if fchown fails.
14621 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14623 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14624 to compare Lisp_Objects.
14625 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14626 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14627 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14629 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14631 * lread.c (read_integer): Unread even EOF character.
14632 (read1): Likewise. Properly record start position of symbol.
14634 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14635 symbol character follows.
14637 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14639 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14640 This works around a problem with the previous change to Fcopy_file.
14641 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14642 and without this change, GCC might complain about discarding
14643 fchown's return value.
14645 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14647 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14649 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14651 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14653 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14655 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14656 it's used from the C level.
14658 * process.c: Use the same condition for POLL_FOR_INPUT in both
14659 keyboard.c and process.c (bug#1858).
14661 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14663 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14664 (Fgnutls_boot): Use it.
14666 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14668 * doc.c (Fsubstitute_command_keys): Revert last change.
14670 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14672 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14673 quotes the next character, and doesn't affect other longer
14674 sequences (bug#8935).
14676 * lread.c (syms_of_lread): Clarify that is isn't only
14677 `eval-buffer' and `eval-defun' that's affected by
14678 `lexical-binding' (bug#8460).
14680 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14682 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14683 bidi redisplay when a line includes both an image and is truncated.
14685 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14687 Fix minor problems found by static checking.
14688 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14689 (elsz): Now a signed constant, not a size_t var. We prefer signed
14690 types to unsigned, to avoid integer comparison confusion. Without
14691 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14692 "cannot optimize loop, the loop counter may overflow", a symptom
14694 * indent.c (Fvertical_motion): Mark locals as initialized.
14695 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14697 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14699 * search.c (Fre_search_backward): Mention `case-fold-search' in
14700 all the re_search_* functions (bug#8138).
14702 * keyboard.c (Fopen_dribble_file): Document when the file is
14705 2011-07-14 Eli Zaretskii <eliz@gnu.org>
14707 * bidi.c (bidi_dump_cached_states): Fix format of displaying
14710 Support bidi reordering of display and overlay strings.
14711 * xdisp.c (compute_display_string_pos)
14712 (compute_display_string_end): Accept additional argument STRING.
14713 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
14714 (reseat_to_string): Initialize bidi_it->string.s and
14715 bidi_it->string.schars.
14716 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
14717 NULL (avoids a crash in bidi_paragraph_init).
14718 Initialize itb.string.lstring.
14719 (init_iterator): Call bidi_init_it only of a valid
14720 buffer position was specified. Initialize paragraph_embedding to
14722 (reseat_to_string): Initialize the bidi iterator.
14723 (display_string): If we need to ignore text properties of
14724 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14725 original value of -1 will not work with bidi.)
14726 (compute_display_string_pos): First arg is now struct
14727 `text_pos *'; all callers changed. Support display properties on
14729 (compute_display_string_end): Support display properties on Lisp
14731 (init_iterator, reseat_1, reseat_to_string): Initialize the
14732 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
14733 when iterating on a string not from display properties).
14734 (compute_display_string_pos, compute_display_string_end):
14735 Fix calculation of the object to scan. Fixes an error when using
14737 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
14738 base_level_stop; instead, set base_level_stop to BEGV.
14739 Fixes crashes in vertical-motion.
14740 (next_element_from_buffer): Improve commentary for when
14741 the iterator is before prev_stop.
14742 (init_iterator): Initialize bidi_p from the default value of
14743 bidi-display-reordering, not from buffer-local value. Use the
14744 buffer-local value only if initializing for buffer iteration.

15217 * alloc.c (mark_buffer):
15218 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
15219 (clone_per_buffer_values): Don't assume that
15220 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
15221 This isn't true in general, and it's particularly not true
15222 if Emacs is configured with --with-wide-int.
15223 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15224 New macros, used in the buffer.c change.

15260 Random fixes. E.g., (random) never returned negative values.
15261 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15262 subseconds part to the entropy, as that's a bit more random.
15263 Prefer signed to unsigned, since the signedness doesn't matter and
15264 in general we prefer signed. When given a limit, use a
15265 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15266 latter isn't right if USE_2_TAGS_FOR_INTS.
15267 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15268 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15272 * textprop.c (text_property_stickiness):
15273 Obey Vtext_property_default_nonsticky.

15280 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15281 This is more efficient than Ffile_directory_p and avoids a minor race.
15283 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15285 * buffer.c (Foverlay_put): Say what the return value is
15288 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15289 is a directory before asking whether to use the file name
15291 (barf_or_query_if_file_exists): Make the "File is a directory"
15292 error be more correct.
15294 * fns.c (Frequire): Remove the mention of the .gz files, since
15295 that's installation-specific, but keep the mention of
15296 `get-load-suffixes'.

15308 Qgnutls_bootprop_verify_error (which is no longer used).
15310 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15311 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15312 Also (re)move comments that are misplaced or no longer relevant.
15314 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15316 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15375 (syms_of_keymap): Defsubr make-composed-keymap.
15376 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

15413 * eval.c (struct backtrace): Simplify and port the data structure.
15414 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15415 signed bit field, as this assumption is not portable and it makes
15416 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15417 "char debug_on_exit : 1" as this is not portable either; instead,
15418 use the portable "unsigned int debug_on_exit : 1". Remove unused
15419 member evalargs. Remove obsolete comments about cc bombing out.
15421 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

15623 Now ptrdiff_t, not int.
15624 (read1): Don't assume doc string length fits in int. Check for
15625 out-of-range doc string lengths.
15626 (read_list): Don't assume file position fits in int.
15627 (read_escape): Check for hex character overflow.
15629 2011-06-22 Leo Liu <sdl.web@gmail.com>
15631 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
15632 Move to minibuffer.el.
15634 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15636 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15637 The following patches are for when GLYPH_DEBUG && !XASSERT.
15638 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15639 * dispnew.c (flush_stdout):
15640 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15641 Mark as externally visible.
15642 * dispnew.c (check_window_matrix_pointers): Now static.
15643 * dispnew.c (window_to_frame_vpos):
15644 * xfns.c (unwind_create_frame):
15645 * xterm.c (x_check_font): Remove unused local.
15646 * scroll.c (CHECK_BOUNDS):
15647 * xfaces.c (cache_fache): Rename local to avoid shadowing.
15648 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
15649 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
15650 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
15651 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
15653 (debug_method_add): Use va_list and vsprintf rather than relying
15654 on undefined behavior with wrong number of arguments.
15655 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15656 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15657 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15658 since we're not interested in debugging glyphs with old libraries.
15659 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15660 GCC 4.6.0's static checking.
15662 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15664 Integer overflow and signedness fixes (Bug#8873).

15673 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
15674 (x_create_bitmap_from_xpm_data):
15675 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
15676 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
15678 * xfaces.c (load_pixmap):
15679 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
15680 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
15681 (.bitmaps_last, struct x_output.icon_bitmap):
15682 Use ptrdiff_t, not int, for bitmap indexes.
15683 (x_allocate_bitmap_record): Check for size overflow.
15684 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
15686 Use ptrdiff_t, not int, for overlay counts.
15687 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
15688 * editfns.c (overlays_around, get_pos_property):
15689 * textprop.c (get_char_property_and_overlay):
15690 * xdisp.c (next_overlay_change, note_mouse_highlight):
15691 * xfaces.c (face_at_buffer_position):
15692 * buffer.c (OVERLAY_COUNT_MAX): New macro.
15693 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
15694 (Fnext_overlay_change, Fprevious_overlay_change)
15695 (mouse_face_overlay_overlaps, Foverlays_in):
15696 Use ptrdiff_t, not int, for sizes.
15697 (overlays_at, overlays_in): Check for size-calculation overflow.
15699 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
15701 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15702 (x_session_initialize): Do not assume string length fits in int.
15704 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15705 This is unlikely, but can occur if DPI is outlandish.
15707 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
15708 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
15710 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
15711 * xrdb.c (magic_file_p, search_magic_path):
15712 Omit last arg SUFFIX; it was always 0. All callers changed.
15713 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
15715 * xfont.c (xfont_match): Avoid need for strlen.
15717 * xfns.c: Don't assume strlen fits in int.
15718 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
15720 * xdisp.c (message_log_check_duplicate): Return intmax_t,
15721 not unsigned long, as we prefer signed integers. All callers changed.
15722 Detect integer overflow in repeat count.
15723 (message_dolog): Don't assume print length fits in 39 bytes.
15724 (display_mode_element): Don't assume strlen fits in int.
15726 * termcap.c: Don't assume sizes fit in int and never overflow.
15727 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
15728 (gobble_line): Check for size-calculation overflow.
15730 * minibuf.c (Fread_buffer):
15731 * lread.c (intern, intern_c_string):
15732 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
15733 Don't assume string length fits in int.
15735 * keyboard.c (parse_tool_bar_item):
15736 * gtkutil.c (style_changed_cb): Avoid need for strlen.
15738 * font.c: Don't assume string length fits in int.
15739 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
15740 Use ptrdiff_t, not int.
15741 (font_intern_prop): Don't assume string length fits in int.
15742 Don't assume integer property fits in fixnum.
15743 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
15745 * filelock.c: Fix some buffer overrun and integer overflow issues.
15746 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
15747 Reformulate so as not to need the command string.
15748 Invoke gzip -cd rather than gunzip, as it's more portable.
15749 (lock_info_type, lock_file_1, lock_file):
15750 Don't assume pid_t and time_t fit in unsigned long.
15751 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15752 (current_lock_owner): Prefer signed type for sizes.
15753 Use memcpy, not strncpy, where memcpy is what is really wanted.
15754 Don't assume (via atoi) that time_t and pid_t fit in int.
15755 Check for time_t and/or pid_t out of range, e.g., via a network share.
15756 Don't alloca where an auto var works fine.
15758 * fileio.c: Fix some integer overflow issues.
15759 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15760 Don't assume string length fits in int.
15761 (directory_file_name): Don't assume string length fits in long.
15762 (make_temp_name): Don't assume pid fits in int, or that its print
15763 length is less than 20.
15765 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15767 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15769 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15771 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15772 We prefer signed integers, even for size calculations.
15774 * emacs.c: Don't assume string length fits in 'int'.
15775 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15776 (main): Don't invoke strlen when not needed.
15778 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15779 (XD_DEBUG_MESSAGE): Don't waste a byte.
15781 * callproc.c (getenv_internal_1, getenv_internal)
15782 (Fgetenv_internal):
15783 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15785 * lread.c (invalid_syntax): Omit length argument.
15786 All uses changed. This doesn't fix a bug, but it simplifies the
15787 code away from its former Hollerith-constant appearance, and it's
15788 one less 'int' to worry about when looking at integer-overflow issues.
15789 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15791 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15792 This didn't break anything, but it didn't help either.
15793 It's confusing to put a bogus integer in a place where the actual
15794 value does not matter.
15795 (LIST_END_P): Remove unused macro and its bogus comment.
15796 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15798 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15799 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15801 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15802 We prefer signed types, and the value cannot exceed the EMACS_INT
15803 range anyway (because otherwise the length would not be representable).
15804 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15805 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15806 This avoids a GCC warning when WIDE_EMACS_INT.
15808 * indent.c (sane_tab_width): New function.
15809 (current_column, scan_for_column, Findent_to, position_indentation)
15810 (compute_motion): Use it. This is just for clarity.
15811 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15813 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15815 * lisp.h (lint_assume): New macro.
15816 * composite.c (composition_gstring_put_cache):
15817 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15819 * editfns.c, insdel.c:
15820 Omit unnecessary forward decls, to simplify future changes.
15822 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15824 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15826 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15827 Use much-faster test for byte-length change.
15828 Don't assume string byte-length fits in 'int'.
15829 Check that character arg fits in 'int'.
15830 (mapcar1): Declare byte as byte, for clarity.
15832 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15834 * fns.c (concat): Catch string overflow earlier.
15835 Do not rely on integer wraparound.
15837 * dispextern.h (struct it.overlay_strings_charpos)
15838 (struct it.selective): Now EMACS_INT, not int.
15839 * xdisp.c (forward_to_next_line_start)
15840 (back_to_previous_visible_line_start)
15841 (reseat_at_next_visible_line_start, next_element_from_buffer):
15842 Don't arbitrarily truncate the value of 'selective' to int.
15844 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15846 * composite.c: Don't truncate sizes to 'int'.
15847 (composition_gstring_p, composition_reseat_it)
15848 (composition_adjust_point): Use EMACS_INT, not int.
15849 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15850 not EMACS_UINT, for indexes.
15852 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15854 * buffer.c: Include <verify.h>.
15855 (struct sortvec.priority, struct sortstr.priority):
15856 Now EMACS_INT, not int.
15857 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15858 (struct sortstr.size, record_overlay_string)
15859 (struct sortstrlist.size, struct sortlist.used):
15860 Don't truncate size to int.
15861 (record_overlay_string): Check for size-calculation overflow.
15862 (init_buffer_once): Check at compile-time, not run-time.
15864 2011-06-22 Jim Meyering <meyering@redhat.com>
15866 Don't leak an XBM-image-sized buffer
15867 * image.c (xbm_load): Free the image buffer after using it.
15869 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15872 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15873 that Sun C diagnosed.
15874 * fns.c (secure_hash): Fix pointer signedness issue.
15875 * intervals.c (static_offset_intervals): New function.
15876 (offset_intervals): Use it.
15878 2011-06-21 Leo Liu <sdl.web@gmail.com>
15881 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15884 * fns.c (secure_hash): Rename from crypto_hash_function and change
15885 the first arg to accept symbols.
15886 (Fsecure_hash): New primitive.
15887 (syms_of_fns): New symbols.
15889 2011-06-20 Deniz Dogan <deniz@dogan.se>
15891 * process.c (Fset_process_buffer): Clarify return value in
15894 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15896 * dispnew.c (add_window_display_history): Use BVAR.
15898 * xdisp.c (debug_method_add): Use BVAR.
15899 (check_window_end, dump_glyph_matrix, dump_glyph)
15900 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15902 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15905 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15906 check till after the cache is created in init_frame_faces.
15908 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15910 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15912 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15914 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15915 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15916 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15918 Improve buffer-overflow checking (Bug#8873).
15919 * fileio.c (Finsert_file_contents):
15920 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15921 Remove the old (too-loose) buffer overflow checks.
15922 They weren't needed, since make_gap checks for buffer overflow.
15923 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15924 The old code merely checked for Emacs fixnum overflow, and relied
15925 on undefined (wraparound) behavior. The new code avoids undefined
15926 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15928 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15929 Tune. Don't use wider integers than needed. Don't use alloca.
15930 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15932 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15934 * insdel.c, lisp.h (buffer_overflow): New function.
15935 (insert_from_buffer_1, replace_range, replace_range_2):
15936 * insdel.c (make_gap_larger):
15937 * editfns.c (Finsert_char):
15938 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15940 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15942 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15944 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15946 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15947 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15949 * fileio.c: Don't assume EMACS_INT fits in off_t.
15950 (emacs_lseek): New static function.
15951 (Finsert_file_contents, Fwrite_region): Use it.
15952 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15954 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15956 * fns.c: Don't overflow int when computing a list length.
15957 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15958 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15959 truncation on 64-bit hosts. Check for QUIT every
15960 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15961 faster and is responsive enough.
15962 (Flength): Report an error instead of overflowing an integer.
15963 (Fsafe_length): Return a float if the value is not representable
15964 as a fixnum. This shouldn't happen except in contrived situations.
15965 (Fnthcdr, Fsort): Don't assume list length fits in int.
15966 (Fcopy_sequence): Don't assume vector length fits in int.
15968 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15969 (header_size, word_size): New constants.
15970 (allocate_vectorlike): Don't check size overflow here.
15971 (allocate_vector): Check it here instead, since this is the only
15972 caller of allocate_vectorlike that could cause overflow.
15973 Check that the new vector's length is representable as a fixnum.
15975 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15976 The previous code was bogus. For example, next_almost_prime (32)
15977 returned 39, which is undesirable as it is a multiple of 3; and
15978 next_almost_prime (24) returned 25, which is a multiple of 5 so
15979 why was the code bothering to check for multiples of 7?
15981 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15983 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15985 Variadic C functions now count arguments with ptrdiff_t.
15986 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15987 Back then I didn't know that the Emacs coding style prefers signed int.
15988 Also, in the meantime I found a few more instances where arguments
15989 were being counted with int, which may truncate counts on 64-bit
15990 machines, or EMACS_INT, which may be unnecessarily wide.
15991 * lisp.h (struct Lisp_Subr.function.aMANY)
15992 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15993 Arg counts are now ptrdiff_t, not size_t.
15994 All variadic functions and their callers changed accordingly.
15995 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15996 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15997 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15998 * callint.c (Fcall_interactively): Check arg count for overflow,
15999 to avoid potential buffer overrun. Use signed char, not 'int',
16000 for 'varies' array, so that we needn't bother to check its size
16001 calculation for overflow.
16002 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16003 * eval.c (apply_lambda):
16004 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16005 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16006 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16008 * callint.c (Fcall_interactively): Don't use index var as event count.
16010 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16011 * mem-limits.h (SIZE): Remove; no longer used.
16013 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16015 Remove unnecessary casts.
16016 * xterm.c (x_term_init):
16017 * xfns.c (x_set_border_pixel):
16018 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16019 These aren't needed now that we assume ANSI C.
16021 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16022 It's more likely to cause problems (due to unsigned overflow)
16025 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16027 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16029 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16031 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16033 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16035 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16037 GLYPH_CODE_FACE returns EMACS_INT, not int.
16038 * dispextern.h (merge_faces):
16039 * xfaces.c (merge_faces):
16040 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16041 Don't assume EMACS_INT fits in int.
16043 * character.h (CHAR_VALID_P): Remove unused parameter.
16044 * fontset.c, lisp.h, xdisp.c: All uses changed.
16046 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16048 * fns.c (concat): Minor tuning based on overflow analysis.
16049 This doesn't fix any bugs. Use int to hold character, instead
16050 of constantly refetching from Emacs object. Use XFASTINT, not
16051 XINT, for value known to be a character. Don't bother comparing
16052 a single byte to 0400, as it's always less.
16054 * floatfns.c (Fexpt):
16055 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16057 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16060 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16062 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16063 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16064 incorrectly succeed when S was a string, because 4294967386 was
16065 truncated before it was used.
16067 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16068 Otherwise, an out-of-range integer could cause undefined behavior
16071 * composite.c: Use int, not EMACS_INT, for characters.
16072 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16073 EMACS_INT, for values that are known to be in character range.
16074 This doesn't fix any bugs but is the usual style inside Emacs and
16075 may generate better code on 32-bit machines.
16077 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16078 This is for reasons similar to the recent CHAR_STRING fix.
16079 * charset.c (Fencode_char): Check that character arg is actually
16080 a character. Pass an int to ENCODE_CHAR.
16081 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16082 wider than 'int', as a compile-time check to prevent future regressions
16085 * character.c (char_string): Remove unnecessary casts.
16087 Make sure a 64-bit char is never passed to CHAR_STRING.
16088 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16089 by silently ignoring the top 32 bits, allowing some values
16090 that were far too large to be valid characters.
16091 * character.h: Include <verify.h>.
16092 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16093 arguments are no wider than unsigned, as a compile-time check
16094 to prevent future regressions in this area.
16096 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16097 (Fsubst_char_in_region):
16099 * xdisp.c (decode_mode_spec_coding):
16100 Adjust to CHAR_STRING's new requirement.
16101 * editfns.c (Finsert_char, Fsubst_char_in_region):
16102 * fns.c (concat): Check that character args are actually
16103 characters. Without this test, these functions did the wrong
16104 thing with wildly out-of-range values on 64-bit hosts.
16106 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16107 These casts should not be needed on 32-bit hosts, either.
16108 * keyboard.c (read_char):
16109 * lread.c (Fload): Remove casts to unsigned.
16111 * lisp.h (UNSIGNED_CMP): New macro.
16112 This fixes comparison bugs on 64-bit hosts.
16113 (ASCII_CHAR_P): Use it.
16114 * casefiddle.c (casify_object):
16115 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16116 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16117 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16118 * dispextern.h (FACE_FROM_ID):
16119 * keyboard.c (read_char): Use UNSIGNED_CMP.
16121 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16122 not to EMACS_INT, to avoid GCC warning.
16124 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16126 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16127 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16128 isn't needed on 32-bit machines.
16130 * buffer.c (Fgenerate_new_buffer_name):
16131 Use EMACS_INT for count, not int.
16132 (advance_to_char_boundary): Return EMACS_INT, not int.
16134 * data.c (Qcompiled_function): Now static.
16136 * window.c (window_body_lines): Now static.
16138 * image.c (gif_load): Rename local to avoid shadowing.
16140 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16141 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16142 * alloc.c (make_save_value): Integer argument is now of type
16143 ptrdiff_t, not int.
16144 (mark_object): Use ptrdiff_t, not int.
16145 * lisp.h (pD): New macro.
16146 * print.c (print_object): Use it.
16148 * alloc.c: Use EMACS_INT, not int, to count objects.
16149 (total_conses, total_markers, total_symbols, total_vector_size)
16150 (total_free_conses, total_free_markers, total_free_symbols)
16151 (total_free_floats, total_floats, total_free_intervals)
16152 (total_intervals, total_strings, total_free_strings):
16153 Now EMACS_INT, not int. All uses changed.
16154 (Fgarbage_collect): Compute overall total using a double, so that
16155 integer overflow is less likely to be a problem. Check for overflow
16156 when converting back to an integer.
16157 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16158 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16159 These were 'int' variables that could overflow on 64-bit hosts;
16160 they were never used, so remove them instead of repairing them.
16161 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16162 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16163 Previously, this ceilinged at INT_MAX, but that doesn't work on
16165 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16167 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16168 (allocate_vectorlike): Check for ptrdiff_t overflow.
16169 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16170 when a (possibly-narrower) signed value would do just as well.
16171 We prefer using signed arithmetic, to avoid comparison confusion.
16173 * alloc.c: Catch some string size overflows that we were missing.
16174 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16175 for convenience in STRING_BYTES_MAX.
16176 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16177 The definition here is exact; the one in lisp.h was approximate.
16178 (allocate_string_data): Check for string overflow. This catches
16179 some instances we weren't catching before. Also, it catches
16180 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16181 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16182 and ptrdiff_t and EMACS_INT are both 64 bits.
16184 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16185 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16186 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16188 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16190 * alloc.c (Fmake_string): Check for out-of-range init.
16192 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16194 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16196 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16198 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16199 xg_get_default_scrollbar_width.
16201 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16202 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16203 (style_changed_cb): Call update_theme_scrollbar_width and call
16204 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16205 all frames (Bug#8505).
16206 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16207 Call gtk_window_set_resizable if HAVE_GTK3.
16208 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16209 and height if HAVE_GTK3 (Bug#8505).
16210 (scroll_bar_width_for_theme): New variable.
16211 (update_theme_scrollbar_width): New function.
16212 (xg_get_default_scrollbar_width): Move code to
16213 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

16216 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16218 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

16222 * frame.c (make_frame): Call other_buffer_safely instead of
16225 * window.c (temp_output_buffer_show): Call display_buffer with
16226 second argument Vtemp_buffer_show_specifiers and reset latter
16227 immediately after the call.
16228 (Vtemp_buffer_show_specifiers): New variable.
16229 (auto_window_vscroll_p, next_screen_context_lines)
16230 (Vscroll_preserve_screen_position): Remove leading asterisks from

16781 (display_prop_intangible_p): Reimplement to call
16782 handle_display_spec instead of single_display_spec_intangible_p.

16794 value of a `display' property is a "replacing spec".
16795 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16796 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

16826 * gnutls.c: Use Emacs's memory allocators.
16827 Without this change, the gnutls library would invoke malloc etc.
16828 directly, which causes problems on non-SYNC_INPUT hosts, and which
16829 runs afoul of improving memory_full behavior. (Bug#8761)
16830 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16831 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16832 xfree instead of the default malloc, realloc, free.
16833 (Fgnutls_boot): No need to check for memory allocation failure,
16834 since xmalloc does that for us.

16858 * alloc.c (allocate_vectorlike):
16859 Check for overflow in vector size calculations.
16860 * ccl.c (ccl_driver):
16861 Check for overflow when converting EMACS_INT to int.

16863 need to be updated by these changes.
16864 * fns.c (make_hash_table, maybe_resize_hash_table):
16865 Check for integer overflow with large hash tables.
16866 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16867 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16868 (SXHASH_REDUCE): New macro.
16869 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16870 Use it instead of discarding useful hash info with large hash values.
16871 (sxhash_float): New function.
16872 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16873 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16874 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16875 Rewrite to use FIXNUM_BITS, as this simplifies things.
16876 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16877 Adjust signatures to match updated version of code.
16878 (consing_since_gc): Now EMACS_INT, since a single hash table can
16879 use more than INT_MAX bytes.

16922 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16923 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16924 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16926 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16928 Make it possible to run ./temacs.
16930 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16931 syms_of_callproc does the same thing. Remove test for
16932 "initialized", do it in the caller.
16933 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16935 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16937 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16938 (read_minibuf): Use get_minibuffer.
16939 (syms_of_minibuf): Use DEFSYM.
16940 (Qmetadata): New var.
16941 * data.c (Qbuffer): Don't make it static.
16942 (syms_of_data): Use DEFSYM.
16944 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16946 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16947 (CCL_CODE_MIN): New macro.
16949 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16951 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16953 * eval.c (Qdebug): Now static.
16954 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16955 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16956 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16958 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16960 * image.c: Various fixes to ImageMagick code comments.
16961 (Fimagemagick_types): Doc fix.
16963 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16965 Minor fixes prompted by GCC 4.6.0 warnings.
16967 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16969 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16970 (x_clipboard_manager_save_all): Move extern decl to ...
16971 * xterm.h: ... here, so that it can be checked for consistency.
16973 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16975 * xselect.c (x_clipboard_manager_save_frame)
16976 (x_clipboard_manager_save_all): New functions.
16977 (Fx_clipboard_manager_save): Lisp function deleted.
16979 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16980 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16982 * xterm.h: Update prototype.
16984 2011-05-28 William Xu <william.xwl@gmail.com>
16986 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16987 exiting (Bug#8239).
16989 2011-05-28 Jim Meyering <meyering@redhat.com>
16991 Avoid a sign-extension bug in crypto_hash_function.
16992 * fns.c (to_uchar): Define.
16993 (crypto_hash_function): Use it to convert some newly-signed
16994 variables to unsigned, to avoid sign-extension bugs. For example,
16995 without this change, (md5 "truc") would evaluate to
16996 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16997 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16998 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17000 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17002 Integer overflow fixes.
17004 * dbusbind.c: Serial number integer overflow fixes.
17005 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17006 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17007 to hold a serial number that is too large for a fixnum.
17008 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17009 Check for serial numbers out of range. Decode any serial number
17010 that was so large that it became a float. (Bug#8722)
17012 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17013 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17014 Use XFASTINT rather than XUINT when numbers are nonnegative.
17015 (xd_append_arg, Fdbus_method_return_internal):
17016 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17017 arguments, check that Lisp number is nonnegative, rather than
17018 silently wrapping negative numbers around. (Bug#8722)
17019 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17022 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17024 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17026 ccl: Add integer overflow checks.
17027 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17028 (IN_INT_RANGE): New macros.
17029 (ccl_driver): Use them to check for integer overflow when
17030 decoding a CCL program. Many of the new checks are whether XINT (x)
17031 fits in int; it doesn't always, on 64-bit hosts. The new version
17032 doesn't catch all possible integer overflows, but it's an
17033 improvement. (Bug#8719)
17035 * alloc.c (make_event_array): Use XINT, not XUINT.
17036 There's no need for unsigned here.
17038 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17039 This follows up to the 2011-05-06 change that substituted uintptr_t
17040 for EMACS_INT. This case wasn't caught back then.
17042 Rework Fformat to avoid integer overflow issues.
17043 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17044 now (part of C89). Include <verify.h>.
17045 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17046 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17047 (Fformat): Avoid the prepass trying to compute sizes; it was only
17048 approximate and thus did not catch overflow reliably. Instead, walk
17049 through the format just once, formatting and computing sizes as we go,
17050 checking for integer overflow at every step, and allocating a larger
17051 buffer as needed. Keep track separately whether the format is
17052 multibyte. Keep only the most-recently calculated precision, rather
17053 than them all. Record whether each argument has been converted to
17054 string. Use EMACS_INT, not int, for byte and char and arg counts.
17055 Support field widths and precisions larger than INT_MAX. Avoid
17056 sprintf's undefined behavior with conversion specifications such as %#d
17057 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17058 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17059 formatting out-of-range floating point numbers with int
17060 formats. (Bug#8668)
17062 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17064 * data.c: Avoid integer truncation in expressions involving floats.
17065 * data.c: Include <intprops.h>.
17066 (arith_driver): When there's an integer overflow in an expression
17067 involving floating point, convert the integers to floating point
17068 so that the resulting value does not suffer from catastrophic
17069 integer truncation. For example, on a 64-bit host (* 4
17070 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17071 Do not rely on undefined behavior after integer overflow.
17073 merge count_size_as_multibyte, parse_str_to_multibyte
17074 * character.c, character.h (count_size_as_multibyte):
17075 Rename from parse_str_to_multibyte; all uses changed.
17076 Check for integer overflow.
17077 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17078 since it's now a duplicate of the other. This is more of
17079 a character than a buffer op, so better that it's in character.c.
17080 * fns.c, print.c: Adjust to above changes.
17082 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17084 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17086 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17088 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17089 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17090 (x_clipboard_manager_save): Now static.
17091 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17093 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17094 (crypto_hash_function): Now static.
17095 Fix pointer signedness problems. Avoid unnecessary initializations.
17097 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17099 * termhooks.h (Vselection_alist): Make it terminal-local.
17101 * terminal.c (create_terminal): Initialize it.
17103 * xselect.c: Support for clipboard managers.
17104 (Vselection_alist): Move to termhooks.h as terminal-local var.
17105 (LOCAL_SELECTION): New macro.
17106 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17107 (symbol_to_x_atom): Remove gratuitous arg.
17108 (x_handle_selection_request, lisp_data_to_selection_data)
17109 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17110 (x_own_selection, x_get_local_selection, x_convert_selection):
17111 New arg, specifying work frame. Use terminal-local Vselection_alist.
17112 (some_frame_on_display): Delete unused function.
17113 (Fx_own_selection_internal, Fx_get_selection_internal)
17114 (Fx_disown_selection_internal, Fx_selection_owner_p)
17115 (Fx_selection_exists_p): New optional frame arg.
17116 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17117 (x_handle_selection_clear): Don't treat other terminals with the
17118 same keyboard specially. Use the terminal-local Vselection_alist.
17119 (x_clear_frame_selections): Use Frun_hook_with_args.
17121 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17123 * xterm.h: Add support for those atoms.
17125 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17127 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17128 (converted_selections, conversion_fail_tag): New global variables.
17129 (x_selection_request_lisp_error): Free the above.
17130 (x_get_local_selection): Remove unnecessary code.
17131 (x_reply_selection_request): Args changed; handle arbitrary array
17132 of converted selections stored in converted_selections.
17133 Separate the XChangeProperty and SelectionNotify steps.
17134 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17135 (x_convert_selection): New function.
17136 (x_handle_selection_event): Simplify.
17137 (x_get_foreign_selection): Don't ignore incoming requests while
17138 waiting for an answer; this will fail when we implement
17139 SAVE_TARGETS, and seems unnecessary anyway.
17140 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17141 (Vx_sent_selection_functions): Doc fix.
17143 2011-05-26 Leo Liu <sdl.web@gmail.com>
17145 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17147 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17149 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17151 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17152 for fringe update if it has periodic bitmap.
17153 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17154 and fringe_bitmap_periodic_p.
17156 * fringe.c (get_fringe_bitmap_data): New function.
17157 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17158 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17159 row. Mark glyph row for fringe update if periodicity changed.
17161 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17162 for fringe update unless it has periodic bitmap.
17164 2011-05-25 Kenichi Handa <handa@m17n.org>
17166 * xdisp.c (get_next_display_element): Set correct it->face_id for
17167 a static composition.
17169 2011-05-24 Leo Liu <sdl.web@gmail.com>
17172 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17174 * fns.c (crypto_hash_function, Fsha1): New function.
17175 (Fmd5): Use crypto_hash_function.
17176 (syms_of_fns): Add Ssha1.
17178 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17180 * gnutls.c: Remove unused macros.
17181 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17182 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17183 Remove macros that are defined and never used.
17184 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17186 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17188 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17189 (Fx_get_selection_internal): Minor cleanup.
17190 (Fx_own_selection_internal): Rename arguments for consistency with
17193 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17195 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17197 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17199 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17201 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17203 * dispnew.c (scrolling_window): Don't exclude the case that the
17204 last enabled row in the desired matrix touches the bottom boundary.
17206 2011-05-21 Glenn Morris <rgm@gnu.org>
17208 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17209 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17210 and add some more files.
17212 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17214 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17215 report_file_error introduced by the change from 2011-05-07.
17217 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17219 * systime.h (Time): Define only if emacs is defined.
17220 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17221 where the include path doesn't have X11/X.h by default. See
17222 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17224 2011-05-20 Kenichi Handa <handa@m17n.org>
17226 * composite.c (find_automatic_composition): Fix previous change.
17228 2011-05-20 Glenn Morris <rgm@gnu.org>
17230 * lisp.mk: New file, split from Makefile.in.
17231 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17232 (shortlisp): Remove.
17233 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17235 2011-05-19 Glenn Morris <rgm@gnu.org>
17237 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17238 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17239 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17240 (lisp): Set the order to that of loadup.el.
17241 (shortlisp): Make it a copy of $lisp.
17242 (SOME_MACHINE_LISP): Remove.
17243 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17244 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17246 2011-05-18 Kenichi Handa <handa@m17n.org>
17248 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17249 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17250 (find_automatic_composition): Mostly rewrite for efficiency.
17252 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17254 * makefile.w32-in: Update dependencies.
17256 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17258 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17259 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17261 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17263 Fix some integer overflow issues, such as string length overflow.
17265 * insdel.c (count_size_as_multibyte): Check for string overflow.
17267 * character.c (lisp_string_width): Check for string overflow.
17268 Use EMACS_INT, not int, for string indexes and lengths; in
17269 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17270 the resulting string length overflows an EMACS_INT; instead,
17271 report a string overflow if no precision given. When checking for
17272 precision exhaustion, use a check that cannot possibly have
17273 integer overflow. (Bug#8675)
17274 * character.h (lisp_string_width): Adjust to new signature.
17276 * alloc.c (string_overflow): New function.
17277 (Fmake_string): Use it. This doesn't change behavior, but saves
17278 a few bytes and will simplify future changes.
17279 * character.c (string_escape_byte8): Likewise.
17280 * lisp.h (string_overflow): New decl.
17282 Fixups, following up to the user-interface timestamp change.
17283 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17284 for UI timestamps, instead of unsigned long.
17285 * msdos.c (mouse_get_pos): Likewise.
17286 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17287 * w32gui.h (Time): Define by including "systime.h" rather than by
17288 declaring it ourselves. (Bug#8664)
17290 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17291 * image.c (clear_image_cache): Likewise.
17293 * term.c (term_mouse_position): Don't assume time_t wraparound.
17295 Be more systematic about user-interface timestamps.
17296 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17297 and sometimes 'EMACS_UINT', to represent these timestamps.
17298 This change causes it to use 'Time' uniformly, as that's what X uses.
17299 This makes the code easier to follow, and makes it easier to catch
17300 integer overflow bugs such as Bug#8664.
17301 * frame.c (Fmouse_position, Fmouse_pixel_position):
17302 Use Time, not unsigned long, for user-interface timestamps.
17303 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17304 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17305 * keyboard.h (last_event_timestamp): Likewise.
17306 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17307 * menu.h (xmenu_show): Likewise.
17308 * term.c (term_mouse_position): Likewise.
17309 * termhooks.h (struct input_event.timestamp): Likewise.
17310 (struct terminal.mouse_position_hook): Likewise.
17311 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17312 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17313 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17314 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17315 what it was before.
17316 * menu.h, termhooks.h: Include "systime.h", for Time.
17318 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17319 Don't assume that the difference between two unsigned long values
17320 can fit into an integer. At this point, we know button_down_time
17321 <= event->timestamp, so the difference must be nonnegative, so
17322 there's no need to cast the result if double-click-time is
17323 nonnegative, as it should be; check that it's nonnegative, just in
17324 case. This bug is triggered when events are more than 2**31 ms
17325 apart (about 25 days). (Bug#8664)
17327 * xselect.c (last_event_timestamp): Remove duplicate decl.
17328 (x_own_selection): Remove needless cast to unsigned long.
17330 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17331 that always fit in int. Use a sentinel instead of a counter, to
17332 avoid a temp and to allay GCC's concerns about possible int overflow.
17333 * frame.h (struct frame): Use int for menu_bar_items_used
17334 instead of EMACS_INT, since it always fits in int.
17336 * menu.c (grow_menu_items): Check for int overflow.
17338 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17340 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17341 Before, the code was not consistent. These values cannot exceed
17342 2**31 - 1 so there's no need to make them unsigned.
17343 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17344 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17345 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17347 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17349 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17350 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17351 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17352 presumably because the widths might not match.
17354 * window.c (size_window): Avoid needless test at loop start.
17356 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17358 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17360 2011-05-12 Drew Adams <drew.adams@oracle.com>
17362 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17364 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17366 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17367 `width' to `bar_area_x' and `bar_area_width', respectively.
17368 (x_scroll_run): Take account of fringe background extension.
17370 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17371 Rename local vars `left' and `width' to `bar_area_x' and
17372 `bar_area_width', respectively.
17373 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17374 background extension.
17376 2011-05-10 Jim Meyering <meyering@redhat.com>
17378 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17380 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17382 * image.c (Finit_image_library): Return t for built-in image types,
17383 like pbm and xbm. (Bug#8640)
17385 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17387 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17389 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17391 * w32console.c (Fset_screen_color): Doc fix.
17392 (Fget_screen_color): New function.
17393 (syms_of_ntterm): Defsubr it.
17395 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17396 unlink the temporary file if Fcall_process didn't create it in the
17398 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17399 child process will be redirected to a file specified with `:file'.
17400 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17401 cue to call_process_cleanup not to close that handle.
17403 2011-05-07 Ben Key <bkey76@gmail.com>
17405 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17406 one of two shell specific rules, either bootstrap-temacs-CMD or
17407 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17408 to the previous implementation of the bootstrap-temacs rule.
17409 The bootstrap-temacs-CMD rule is similar to the previous
17410 implementation of the bootstrap-temacs rule except that it
17411 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17414 These changes, along with some changes to nt/configure.bat,
17415 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17416 earlier fix to add support for --cflags and --ldflags options
17417 that include quotes so that it works whether make uses cmd or
17420 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17422 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17423 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17425 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17426 a string. Handle both cases.
17427 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17428 (Fdbus_register_method): Use Qinvalid_function.
17430 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17432 * makefile.w32-in: Update dependencies.
17433 (LISP_H): Add inttypes.h and stdin.h.
17434 (PROCESS_H): Add unistd.h.
17436 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17438 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17439 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17441 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17443 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17445 * term.c (vfatal): Remove stray call to va_end.
17446 It's not needed and the C Standard doesn't allow it here anyway.
17448 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17449 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17451 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17454 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17456 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17458 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17460 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17462 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17464 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17465 * charset.c (Fdefine_charset_internal): Don't initialize
17466 charset.code_space[15]. The value was garbage, on hosts with
17467 32-bit int (Bug#8600).
17469 * lread.c (read_integer): Be more consistent with string-to-number.
17470 Use string_to_number to do the actual conversion; this avoids
17471 rounding errors and fixes some other screwups. Without this fix,
17472 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17473 (digit_to_number): Move earlier, for benefit of read_integer.
17474 Return -1 if the digit is out of range for the base, -2 if it is
17475 not a digit in any supported base. (Bug#8602)
17477 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17479 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17480 to match comment at start of function. This also removes a
17481 GCC warning about overflow in a 32+64-bit port.
17483 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17485 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17486 Reported by Stefan Monnier in
17487 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17488 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17489 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17491 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17492 (EMACS_UINTPTR): Likewise, with uintptr_t.
17494 * lisp.h: Prefer 64-bit EMACS_INT if available.
17495 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17496 on 32-bit hosts that have 64-bit int, so that they can access
17498 However, temporarily disable this change unless the temporary
17499 symbol WIDE_EMACS_INT is defined.
17501 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17503 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17504 This removes an assumption that EMACS_INT and long are the same
17505 width as pointers. The assumption is true for Emacs porting targets
17506 now, but we want to make other targets possible.
17507 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17508 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17509 In the rest of the code, change types of integers that hold casted
17510 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17511 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17512 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17513 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17514 No need to cast type when ORing.
17515 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17516 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17517 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17518 assume EMACS_INT is the same width as char *.
17519 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17520 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17521 Remove no-longer-needed casts.
17522 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17523 (xg_tool_bar_help_callback, xg_make_tool_item):
17524 Use EMACS_INTPTR to hold an integer
17525 that will be cast to void *; this can avoid a GCC warning
17526 if EMACS_INT is not the same width as void *.
17527 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17528 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17529 (current_message_1, set_message_1):
17530 Use a local to convert to proper width without a cast.
17531 * xmenu.c (dialog_selection_callback): Likewise.
17533 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17534 Also, don't assume VALBITS / RAND_BITS is less than 5,
17535 and don't rely on undefined behavior when shifting a 1 left into
17537 * lisp.h (get_random): Change signature to match.
17539 * lread.c (hash_string): Use size_t, not int, for hash computation.
17540 Normally we prefer signed values; but hashing is special, because
17541 it's better to use unsigned division on hash table sizes so that
17542 the remainder is nonnegative. Also, size_t is the natural width
17543 for hashing into memory. The previous code used 'int', which doesn't
17544 retain enough info to hash well into very large tables.
17545 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17547 * dbusbind.c: Don't possibly lose pointer info when converting.
17548 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17549 Use XPNTR rather than XHASH, so that the high-order bits of
17550 the pointer aren't lost when converting through void *.
17552 * eval.c (Fautoload): Don't double-shift a pointer.
17554 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17556 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17558 * gnutls.c (DEF_GNUTLS_FN):
17559 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17561 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17563 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17566 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17568 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17569 New version that can reserve upto 2GB of heap space.
17571 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17573 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17575 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17577 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17578 `gnutls_certificate_set_x509_key_file'.
17580 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17582 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17583 Update dependencies.
17585 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17587 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17588 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17589 Remove unused parameter `fildes'.
17590 * process.c (read_process_output, send_process): Don't pass it.
17592 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17594 Fix previous change: the library cache is defined in w32.c.
17595 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17596 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17598 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17600 Implement dynamic loading of GnuTLS on Windows.
17602 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17603 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17604 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17607 * gnutls.c (Qgnutls_dll): Define.
17608 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17609 (gnutls_*): Declare function pointers.

17613 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17614 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17615 (emacs_gnutls_write, emacs_gnutls_read)
17616 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17617 (Fgnutls_available_p): New function.
17618 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

17628 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17630 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17631 (w32_delayed_load): Move from image.c. When loading a library, record
17632 its filename in the :loaded-from property of the library id.
17633 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17634 Initialize and staticpro them.
17635 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.

17638 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17639 instead of gnutls_record_check_pending.
17641 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17643 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17645 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17646 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17649 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17651 * xterm.c (x_set_frame_alpha): Do not set property on anything

17675 (wait_for_termination, interruptible_wait_for_termination):
17676 Move after wait_for_termination_1.
17678 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
17680 * sysdep.c (interruptible_wait_for_termination): New function
17681 which is like wait_for_termination, but allows keyboard
17684 * callproc.c (Fcall_process): Add (:file "file") as an option for
17686 (Fcall_process_region): Ditto.
17688 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17690 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17691 rather than `XVECTOR (FOO)->size'.
17693 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17694 inttypes.h, as a gnulib replacement is used if it not available in
17697 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17699 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17700 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17701 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17703 * coding.c (coding_alloc_by_realloc): Error out if destination
17704 will grow beyond MOST_POSITIVE_FIXNUM.
17705 (decode_coding_emacs_mule): Abort if there isn't enough place in

17718 * window.c (window_scroll_line_based): Use a marker instead of
17719 simple variables to record original value of point. (Bug#7952)
17721 * doprnt.c (doprnt): Fix the case where a multibyte sequence
17722 produced by %s or %c overflows available buffer space. (Bug#8545)
17724 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17726 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

17761 Improve `doprnt' and its usage. (Bug#8545)
17762 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17763 `format_end'. Remove support for %l as a conversion specifier.
17764 Don't use xrealloc. Improve diagnostics when the %l size modifier
17765 is used. Update the commentary.
17767 * eval.c (verror): Simplify calculation of size_t.
17769 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17772 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17774 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17777 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17779 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17780 This makes this file independent of the recent pseudovector change.
17782 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17784 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17786 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17787 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17788 Remove unused local.
17789 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17791 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17792 GCC 4.6.0 optimizes based on type-based alias analysis.
17793 For example, if b is of type struct buffer * and v of type struct
17794 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17795 != &v->size, and therefore "v->size = 1; b->size = 2; return
17796 v->size;" must therefore return 1. This assumption is incorrect
17797 for Emacs, since it type-puns struct Lisp_Vector * with many other
17798 types. To fix this problem, this patch adds a new type struct
17799 vectorlike_header that documents the constraints on layout of vectors
17800 and pseudovectors, and helps optimizing compilers not get fooled
17801 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17802 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17803 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17805 (XSETPVECTYPE): Rewrite in terms of new macro.
17806 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17807 This is a bit clearer, and further avoids the possibility of
17808 undesirable aliasing.
17809 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17810 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17811 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17812 since Lisp_Subr is a special case (no "next" field).
17813 (ASIZE): Now uses header.size rather than size.
17814 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17815 to avoid the hassle of writing XVECTOR (foo)->header.size.
17816 (struct vectorlike_header): New type.
17817 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17818 object, to help avoid aliasing.
17819 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17820 (SUBRP): Likewise, since Lisp_Subr is a special case.
17821 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17822 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17823 (struct Lisp_Hash_Table): Combine first two members into a single
17824 struct vectorlike_header member. All uses of "size" and "next" members
17825 changed to be "header.size" and "header.next".
17826 * buffer.h (struct buffer): Likewise.
17827 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17828 * frame.h (struct frame): Likewise.
17829 * process.h (struct Lisp_Process): Likewise.
17830 * termhooks.h (struct terminal): Likewise.
17831 * window.c (struct save_window_data, struct saved_window): Likewise.
17832 * window.h (struct window): Likewise.
17833 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17834 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17835 * buffer.c (init_buffer_once): Likewise.
17836 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17838 * process.c (Fformat_network_address): Use local var for size,
17841 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17843 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17844 * data.c (atof): Remove decl; no longer used or needed.
17845 (digit_to_number): Move to lread.c.
17846 (Fstring_to_number): Use new string_to_number function, to be
17847 consistent with how the Lisp reader treats infinities and NaNs.
17848 Do not assume that floating-point numbers represent EMACS_INT
17849 without losing information; this is not true on most 64-bit hosts.
17850 Avoid double-rounding errors, by insisting on integers when
17851 parsing non-base-10 numbers, as the documentation specifies.
17852 * lisp.h (string_to_number): New decl, replacing ...
17853 (isfloat_string): Remove.
17854 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17855 (read1): Do not accept +. and -. as integers; this
17856 appears to have been a coding error. Similarly, do not accept
17857 strings like +-1e0 as floating point numbers. Do not report
17858 overflow for integer overflows unless the base is not 10 which
17859 means we have no simple and reliable way to continue.
17860 Break out the floating-point parsing into a new
17861 function string_to_number, so that Fstring_to_number parses
17862 floating point numbers consistently with the Lisp reader.
17863 (digit_to_number): Move here from data.c. Make it static inline.
17864 (E_CHAR, EXP_INT): Remove, replacing with ...
17865 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17866 (string_to_number): New function, replacing isfloat_string.
17867 This function checks for valid syntax and produces the resulting
17868 Lisp float number too. Rework it so that string-to-number
17869 no longer mishandles examples like "1.0e+". Use strtoumax,
17870 so that overflow for non-base-10 numbers is reported only when
17871 there's no portable and simple way to convert to floating point.
17873 * textprop.c (set_text_properties_1): Rewrite for clarity,
17874 and to avoid GCC warning about integer overflow.
17876 * intervals.h (struct interval): Use EMACS_INT for members
17877 where EMACS_UINT might cause problems. See
17878 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17879 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17880 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17882 (offset_intervals): Tell GCC not to worry about length overflow
17883 when negating a negative length.
17885 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17886 (overrun_check_free): Likewise.
17888 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17889 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17892 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17893 (gnutls_make_error): Rename local to avoid shadowing.
17894 (gnutls_emacs_global_deinit): ifdef out; not used.
17895 (Fgnutls_boot): Use const for pointer to readonly storage.
17896 Comment out unused local. Fix pointer signedness problems.
17898 * lread.c (openp): Don't stuff size_t into an 'int'.
17899 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17900 about possible signed overflow.
17902 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17903 (GDK_KEY_g): Don't define if already defined.
17904 (xg_prepare_tooltip): Avoid pointer signedness problem.
17905 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17907 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17908 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17910 * xfns.c (Fx_window_property): Simplify a bit,
17911 to make a bit faster and to avoid GCC 4.6.0 warning.
17912 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17914 * fns.c (internal_equal): Don't assume size_t fits in int.
17916 * alloc.c (compact_small_strings): Tighten assertion a little.
17918 Replace pEd with more-general pI, and fix some printf arg casts.
17919 * lisp.h (pI): New macro, generalizing old pEd macro to other
17920 conversion specifiers. For example, use "...%"pI"d..." rather
17921 than "...%"pEd"...".
17922 (pEd): Remove. All uses replaced with similar uses of pI.
17923 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17924 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17925 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17926 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17927 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17928 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17929 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17931 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17932 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17933 * print.c (safe_debug_print, print_object): Likewise.
17934 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17936 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17937 avoiding the 0 flag, which is not portable.
17938 * process.c (Fmake_network_process): Use pI to avoid cast.
17939 * region-cache.c (pp_cache): Likewise.
17940 * xdisp.c (decode_mode_spec): Likewise.
17941 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17942 behavior on 64-bit hosts with printf arg.
17943 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17944 (x_stop_queuing_selection_requests): Likewise.
17945 (x_get_window_property): Don't truncate byte count to an 'int'
17948 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17949 here, since it parses constructs like leading '-' and spaces,
17950 which are not wanted; and it overflows with large numbers.
17951 Instead, simply match F[0-9]+, which is what is wanted anyway.
17953 * alloc.c: Remove unportable assumptions about struct layout.
17954 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17955 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17956 (allocate_vectorlike, make_pure_vector): Use the new macros,
17957 plus offsetof, to remove unportable assumptions about struct layout.
17958 These assumptions hold on all porting targets that I know of, but
17959 they are not guaranteed, they're easy to remove, and removing them
17960 makes further changes easier.
17962 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17963 This doesn't fix a bug but makes the code clearer.
17964 (string_overrun_cookie): Now const. Use initializers that
17965 don't formally overflow signed char, to avoid warnings.
17966 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17967 can cause Emacs to crash when string overrun checking is enabled.
17968 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17969 multiple of sizeof (EMACS_INT); it need not be, if
17970 alignof(EMACS_INT) < sizeof (EMACS_INT).
17971 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17973 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17980 supposed to be handshaking. (Bug#8556)
17981 Reported by Paul Eggert <eggert@cs.ucla.edu>.
17983 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
17985 * lisp.h (Qdebug): List symbol.
17986 * eval.c (Qdebug): Restore global linkage.

17988 (handle_user_signal): Break into debugger when debug-on-event
17989 matches the current signal symbol.
17991 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
17993 * alloc.c (check_sblock, check_string_bytes)
17994 (check_string_free_list): Convert to standard C.
17996 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
17998 * w32.c (emacs_gnutls_push): Fix typo.
18000 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18002 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18003 "cast to pointer from integer of different size".
18005 Improve doprnt and its use in verror. (Bug#8545)
18006 * doprnt.c (doprnt): Document the set of format control sequences
18007 supported by the function. Use SAFE_ALLOCA instead of always
18010 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18011 is one byte too soon. Don't use xrealloc; instead xfree and
18014 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18016 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18019 * gnutls.c: Renamed global_initialized to
18020 gnutls_global_initialized. Added internals for the
18021 :verify-hostname-error, :verify-error, and :verify-flags
18022 parameters of `gnutls-boot' and documented those parameters in the
18023 docstring. Start callback support.
18024 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18025 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18026 on error. Return error code.

18028 (emacs_gnutls_read): Likewise.
18029 (Fgnutls_boot): Return handshake error code.

18093 <char-direction-table>: Deleted.
18095 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18097 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
18098 * doprnt.c: Include limits.h.
18099 (SIZE_MAX): New macro.
18100 (doprnt): Return a size_t value. 2nd arg is now size_t.
18101 Many local variables are now size_t instead of int or unsigned.
18102 Improve overflow protection. Support `l' modifier for integer
18103 conversions. Support %l conversion. Don't assume an EMACS_INT
18104 argument for integer conversions and for %c.
18106 * lisp.h (doprnt): Restore prototype.
18108 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18109 $(SRC)/character.h.
18111 * Makefile.in (base_obj): Add back doprnt.o.
18113 * deps.mk (doprnt.o): Add back prerequisites.
18114 (callint.o): Depend on character.h.
18116 * eval.c (internal_lisp_condition_case): Include the handler
18117 representation in the error message.
18118 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
18119 when breaking from the loop.
18121 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
18123 * callint.c (Fcall_interactively): When displaying error message
18124 about invalid control letter, pass the character's codepoint, not
18125 a pointer to its multibyte form. Improve display of the character
18126 in octal and display also its hex code.
18128 * character.c (char_string): Use %x to display the (unsigned)
18129 codepoint of an invalid character, to avoid displaying a bogus
18132 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18133 `error', not SYMBOL_NAME itself.
18135 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18136 character arguments to `error'.
18138 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18139 to `error' in error message about FINAL_CHAR argument. Make sure
18140 FINAL_CHAR is a character, and use %c when it is passed as
18141 argument to `error'.

18205 Define only if needed.
18207 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18208 by pacifying GCC about it. Maybe it's time to retire it?
18209 * xfaces.c (USG, __TIMEVAL__): Likewise.
18211 * dispextern.h (struct redisplay_interface): Rename param
18212 to avoid shadowing.
18213 * termhooks.h (struct terminal): Likewise.
18214 * xterm.c (xembed_send_message): Likewise.
18216 * insdel.c (make_gap_smaller): Define only if
18217 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
18219 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
18222 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
18223 so that we aren't warned about unused symbols.
18225 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
18227 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
18229 * xfns.c (x_real_positions): Mark locals as initialized.
18231 * xmenu.c (xmenu_show): Don't use uninitialized vars.
18233 * xterm.c: Fix problems found by static analysis with other toolkits.
18234 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
18235 (x_dispatch_event): Declare static if USE_GTK, and
18236 define if USE_GTK || USE_X_TOOLKIT.
18237 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.

18330 * nsfont.m: Fixed bugs in ns_get_family and
18331 ns_descriptor_to_entity that were caused by using free to
18332 deallocate memory blocks that were allocated by xmalloc (via

18334 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18335 --enable-checking=xmallocoverrun). xfree is now used to
18336 deallocate these memory blocks.

18677 * ccl.c (Vccl_program_table): Now static.
18678 (check_ccl_update): Remove; unused.
18680 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
18681 * category.h: ... from here.
18682 * category.c (check_category_table, set_category_set): Now static.
18684 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
18685 * lisp.h: Remove these decls.
18687 * buffer.c (buffer_count): Remove unused var.
18689 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
18690 so that it's not optimized away.
18691 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
18692 * dispextern.h (bidi_dump_cached_states): Remove, since it's
18693 exported only to the debugger.
18695 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
18696 * atimer.h (run_all_atimers): Remove; not exported.
18698 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
18699 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
18700 was inaccessible from Lisp.
18701 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
18702 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
18704 alloc.c: Import and export fewer symbols, and remove unused items.
18705 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
18707 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
18708 it's not optimized away by whole-program optimization.
18709 (message_enable_multibyte, free_misc): Remove.
18710 (catchlist, handlerlist, mark_backtrace):
18711 Declare only if BYTE_MARK_STACK.
18712 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
18713 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
18714 (message_enable_multibyte): Remove decl.
18715 (free_misc, interval_free_list, float_block, float_block_index):
18716 (n_float_blocks, float_free_list, cons_block, cons_block_index):
18717 (cons_free_list, last_marked_index):
18719 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
18720 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
18721 (mark_backtrace): Define only if BYTE_MARK_STACK.
18722 * xdisp.c (message_enable_multibyte): Now static.
18724 Declare Lisp_Object Q* variables to be 'static' if not exported.
18725 This makes it easier for human readers (and static analyzers)
18726 to see whether these variables are used from other modules.
18727 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
18728 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
18729 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

18732 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
18733 * xmenu.c, xselect.c:
18734 Declare Q* vars static if they are not used in other modules.
18735 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
18736 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
18737 Remove decls of unexported vars.
18738 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
18740 * lisp.h (DEFINE_FUNC): Make sname 'static'.
18742 Make Emacs functions such as Fatom 'static' by default.
18743 This makes it easier for human readers (and static analyzers)
18744 to see whether these functions can be called from other modules.
18745 DEFUN now defines a static function. To make the function external
18746 so that it can be used in other C modules, use the new macro DEFUE.
18747 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
18748 (Finit_image_library):
18749 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
18750 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
18751 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18752 Remove decls, since these functions are now static.
18753 (Funintern, Fget_internal_run_time): New decls, since these functions
18754 were already external.
18756 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
18757 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

18763 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
18764 Mark functions with DEFUE instead of DEFUN,
18765 if they are used in other modules.
18766 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18767 decls for now-static functions.
18768 * buffer.h (Fdelete_overlay): Remove decl.
18769 * callproc.c (Fgetenv_internal): Mark as internal.
18770 * composite.c (Fremove_list_of_text_properties): Remove decl.

18776 (Funintern): Remove extern decl; now in .h file where it belongs.
18777 * fileio.c (Fmake_symbolic_link): New forward static decl.
18778 * image.c (Finit_image_library): New forward static decl.
18779 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
18780 * intervals.h (Fprevious_property_change):
18781 (Fremove_list_of_text_properties): Remove decls.
18782 * keyboard.c (Fthis_command_keys): Remove decl.
18783 (Fcommand_execute): New forward static decl.
18784 * keymap.c (Flookup_key): New forward static decl.
18785 (Fcopy_keymap): Now static.
18786 * keymap.h (Flookup_key): Remove decl.
18787 * process.c (Fget_process): New forward static decl.
18788 (Fprocess_datagram_address): Mark as internal.

18799 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
18801 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
18804 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18806 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18807 when at ZV. (Bug#8487)
18809 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18811 * charset.c (Fclear_charset_maps): Use xfree instead of free.

18814 * sound.c (sound_cleanup, alsa_close): Likewise.
18815 * termcap.c (tgetent): Likewise.
18816 * xfns.c (x_default_font_parameter): Likewise.
18817 * xsettings.c (read_and_apply_settings): Likewise.
18819 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18820 (overrun_check_free): Protoize.
18822 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18824 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18825 since callers should never pass a negative size.
18826 Change the signature to match that of plain 'read' and 'write'; see
18827 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18828 * lisp.h: Update prototypes of emacs_write and emacs_read.
18830 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18832 * xdisp.c (redisplay_window): Don't try to determine the character
18833 position of the scroll margin if the window start point w->startp
18834 is outside the buffer's accessible region. (Bug#8468)
18836 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18838 Fix write-region and its subroutines for buffers > 2GB.
18839 * fileio.c (a_write, e_write): Modify declaration of arguments and
18840 local variables to support buffers larger than 2GB.
18841 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18843 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18844 argument, local variables, and return value.
18846 * lisp.h: Update prototypes of emacs_write and emacs_read.
18848 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18850 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18852 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18854 Fix more problems found by GCC 4.6.0's static checks.
18856 * xdisp.c (vmessage): Use a better test for character truncation.
18858 * charset.c (load_charset_map): <, not <=, for optimization,
18859 and to avoid potential problems with integer overflow.
18860 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18861 * casetab.c (set_identity, shuffle): Likewise.
18862 * editfns.c (Fformat): Likewise.
18863 * syntax.c (skip_chars): Likewise.
18865 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18866 This also lets GCC 4.6.0 generate slightly better loop code.
18868 * callint.c (Fcall_interactively): <, not <=, for optimization.
18869 (Fcall_interactively): Count the number of arguments produced,
18870 not the number of arguments given. This is simpler and lets GCC
18871 4.6.0 generate slightly better code.
18873 * ftfont.c: Distingish more carefully between FcChar8 and char.
18874 The previous code passed unsigned char * to a functions like
18875 strlen and xstrcasecmp that expect char *, which does not
18876 conform to the C standard.
18877 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18878 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18879 char * when the C standard requires it.
18881 * keyboard.c (read_char): Remove unused var.
18883 * eval.c: Port to Windows vsnprintf (Bug#8435).
18884 Include <limits.h>.
18885 (SIZE_MAX): Define if the headers do not.
18886 (verror): Do not give up if vsnprintf returns a negative count.
18887 Instead, grow the buffer. This ports to Windows vsnprintf, which
18888 does not conform to C99. Problem reported by Eli Zaretskii.
18889 Also, simplify the allocation scheme, by avoiding the need for
18890 calling realloc, and removing the ALLOCATED variable.
18892 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18894 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18895 But keep the doprint source code for now, as we might revamp it
18896 and use it again (Bug#8435).
18897 * lisp.h (doprnt): Remove.
18898 * Makefile.in (base_obj): Remove doprnt.o.
18899 * deps.mk (doprnt.o): Remove.
18901 error: Print 32- and 64-bit integers portably (Bug#8435).
18902 Without this change, on typical 64-bit hosts error ("...%d...", N)
18903 was used to print both 32- and 64-bit integers N, which relied on
18904 undefined behavior.
18905 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18906 * lisp.h (error, verror): Mark as printf-like functions.
18907 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18908 Report overflow in size calculations when allocating printf buffer.
18909 Do not truncate output string at its first null byte.
18910 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18911 Truncate the output at a character boundary, since vsnprintf does not
18913 * charset.c (check_iso_charset_parameter): Convert internal
18914 character to string before calling 'error', since %c now has the
18916 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18917 overflow when computing char to be passed to 'error'. Do not
18918 pass Lisp_Object to 'error'; pass the integer instead.
18919 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18920 formatted with plain %d.
18922 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18924 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18926 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18928 * xterm.c (x_catch_errors): Remove duplicate declaration.
18930 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18932 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18934 2011-04-10 Jim Meyering <meyering@redhat.com>
18936 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18937 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18938 return ssize_t not "int", and use size_t as the buffer length.
18939 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18940 * gnutls.h: Update declarations.
18941 * process.c (read_process_output): Use ssize_t, to match.
18942 (send_process): Likewise.
18944 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18946 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18948 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18950 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18951 Use unsigned char, to match FcChar8 type definition.
18953 * xterm.c (handle_one_xevent):
18954 * xmenu.c (create_and_show_popup_menu):
18955 * xselect.c (x_decline_selection_request)
18956 (x_reply_selection_request): Avoid type-punned deref of X events.
18958 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18960 Fix some uses of `int' instead of EMACS_INT.
18961 * search.c (string_match_1, fast_string_match)
18962 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18963 (scan_buffer, find_next_newline_no_quit)
18964 (find_before_next_newline, search_command, Freplace_match)
18965 (Fmatch_data): Make some `int' variables be EMACS_INT.
18967 * xdisp.c (display_count_lines): 3rd argument and return value now
18968 EMACS_INT. All callers changed.
18969 (pint2hrstr): Last argument is now EMACS_INT.
18971 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18972 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18973 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18974 (decode_coding_utf_16, decode_coding_emacs_mule)

18984 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18985 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18987 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18988 (encode_invocation_designation): Last argument P_NCHARS is now
18990 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18991 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18993 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18996 * ccl.c (Fccl_execute_on_string): Declare some variables
18999 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19001 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19003 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19005 * process.c (Fformat_network_address): Doc fix.
19007 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19009 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19011 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19013 * keyboard.c (read_char): Call Lisp function help-form-show,
19014 instead of using internal_with_output_to_temp_buffer.
19015 (Qhelp_form_show): New var.
19016 (syms_of_keyboard): Use DEFSYM macro.
19018 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19025 (list_processes_1): Delete.
19027 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19029 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19031 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19033 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19035 Fix more problems found by GCC 4.6.0's static checks.
19037 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19039 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19041 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19043 * xdisp.c (vmessage): Mark as a printf-like function.
19045 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19047 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19049 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19050 printf-like functions.

19052 to system-supplied API.
19054 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19056 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19057 This avoids several warnings with gcc -Wstrict-overflow.
19058 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19059 directly, rather than having caller test rule sign. This avoids
19060 some unnecessary tests.
19061 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19062 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19063 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19065 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19066 (xfont_open): Avoid unnecessary tests.
19068 * composite.c (composition_gstring_put_cache): Use unsigned integer.

19077 by using the new macro.
19079 * textprop.c (set_text_properties_1): Change while to do-while,
19080 since the condition is always true at first.
19082 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19083 (interval_deletion_adjustment): Return unsigned value.
19086 * process.c (list_processes_1, create_pty, read_process_output):

19115 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19116 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19117 can always succeed if overflow has undefined behavior.

19120 (wordify): Omit three unnecessary tests.
19122 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19123 All callers changed. This avoids the need for an unused var.
19125 * casefiddle.c (casify_region): Remove var that is set but not used.
19127 * dired.c (file_name_completion): Remove var that is set but not used.
19129 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19131 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19132 (Finsert_file_contents): Remove unnecessary code checking fd.
19134 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19135 Check for integer overflow on size calculations.
19137 * buffer.c (Fprevious_overlay_change): Remove var that is set
19140 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19141 Remove vars that are set but not used.
19142 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19143 (timer_check_2): Mark vars as initialized.
19145 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19147 * image.c (lookup_image): Remove var that is set but not used.
19148 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19150 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19151 that are set but not used.
19153 * xfns.c (make_invisible_cursor): Don't return garbage
19154 if XCreateBitmapFromData fails (Bug#8410).
19156 * xselect.c (x_get_local_selection, x_handle_property_notify):
19157 Remove vars that are set but not used.
19159 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19160 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19162 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19163 Remove var that is set but not used.
19164 (scroll_bar_windows_size): Now size_t, not int.
19165 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19166 Check for overflow.
19168 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19169 (map_tty_color) [!defined MSDOS]: Likewise.
19171 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19173 * coding.c: Remove vars that are set but not used.
19174 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19175 All callers changed.
19176 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19177 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19178 (decode_coding_charset): Remove vars that are set but not used.
19180 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19181 that is set but not used.
19183 * print.c (print_object): Remove var that is set but not used.
19185 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19186 The gnulib version avoids calling malloc in the usual case,
19187 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19188 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19189 * filelock.c (current_lock_owner): Likewise.
19190 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19191 * sysdep.c: Include allocator.h, careadlinkat.h.
19192 (emacs_no_realloc_allocator): New static constant.
19193 (emacs_readlink): New function.
19194 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19195 ../lib/careadlinkat.h.
19197 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19199 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19200 first non-nil return value).

19214 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19215 and thereabouts. All callers changed.
19216 (get_per_char_metric): Remove parameter `f', unused since
19217 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19219 2011-04-02 Jim Meyering <meyering@redhat.com>
19221 do not dereference NULL upon failed strdup
19222 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19223 (ns_get_family): Likewise.
19225 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19227 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19229 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19231 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19234 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19236 Add lexical binding.
19238 * window.c (Ftemp_output_buffer_show): New fun.
19239 (Fsave_window_excursion):
19240 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19242 * lread.c (lisp_file_lexically_bound_p): New function.
19243 (Fload): Bind Qlexical_binding.
19244 (readevalloop): Remove `evalfun' arg.
19245 Bind Qinternal_interpreter_environment.
19246 (Feval_buffer): Bind Qlexical_binding.
19247 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19249 (syms_of_lread): Declare `lexical-binding'.
19251 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19253 * keyboard.c (eval_dyn): New fun.
19254 (menu_item_eval_property): Use it.
19256 * image.c (parse_image_spec): Use Ffunctionp.
19258 * fns.c (concat, mapcar1): Accept byte-code-functions.
19260 * eval.c (Fsetq): Handle lexical vars.
19261 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19262 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19263 (FletX, Flet): Obey lexical binding.
19264 (Fcommandp): Handle closures.
19265 (Feval): New `lexical' arg.
19266 (eval_sub): New function extracted from Feval. Use it almost
19267 everywhere where Feval was used. Look up vars in lexical env.
19269 (Ffunctionp): Move from subr.el.
19270 (Ffuncall): Handle closures.
19271 (apply_lambda): Remove `eval_flags'.
19272 (funcall_lambda): Handle closures and new byte-code-functions.
19273 (Fspecial_variable_p): New function.
19274 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19275 but without exporting it to Lisp.
19277 * doc.c (Fdocumentation, store_function_docstring):
19278 * data.c (Finteractive_form): Handle closures.
19280 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19283 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19285 (exec_byte_code): New function extracted from Fbyte_code to handle new
19286 calling convention for byte-code-functions. Add new byte-codes.
19288 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19290 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19292 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19294 * xdisp.c (redisplay_internal): Fix prototype.
19296 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19298 * xdisp.c (SCROLL_LIMIT): New macro.
19299 (try_scrolling): Use it when setting scroll_limit.
19300 Limit scrolling to 100 screen lines.
19301 (redisplay_window): Even when falling back on "recentering",
19302 position point in the window according to scroll-conservatively,
19303 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19305 (try_scrolling): When point is above the window, allow searching
19306 as far as scroll_max, or one screenful, to compute vertical
19307 distance from PT to the scroll margin position. This prevents
19308 try_scrolling from unnecessarily failing when
19309 scroll-conservatively is set to a value slightly larger than the
19310 window height. Clean up the case of PT below the margin at bottom
19311 of window: scroll_max can no longer be INT_MAX. When aggressive
19312 scrolling is in use, don't let point enter the opposite scroll
19313 margin as result of the scroll.
19314 (syms_of_xdisp) <scroll-conservatively>: Document the
19315 threshold of 100 lines for never-recentering scrolling.
19317 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

19322 (message_log_check_duplicate): Remove parameters `prev_bol' and
19323 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19324 (redisplay_internal): Remove parameter `preserve_echo_area',
19325 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19327 * indent.c (Fvertical_motion):
19328 * window.c (window_scroll_pixel_based, Frecenter):
19329 Don't pass `need_y_p' to `move_it_by_lines'.
19331 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19333 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19334 steal a few bits to be more compact.
19335 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19336 Remove unneeded casts.
19338 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19340 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19342 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19343 binding" message (bug#7967).
19345 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19347 Fix more problems found by GCC 4.6.0's static checks.
19349 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19350 Remove unused local var.
19352 * editfns.c (Fmessage_box): Remove unused local var.
19354 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19355 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19356 Omit unused local vars.
19357 * window.c (shrink_windows): Omit unused local var.
19358 * menu.c (digest_single_submenu): Omit unused local var.
19359 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19360 Omit unused local var.
19362 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19363 Don't assume string length fits in int.
19364 (keyremap_step, read_key_sequence): Use size_t for sizes.
19365 (read_key_sequence): Don't check last_real_key_start redundantly.
19367 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19368 instead of alloca (Bug#8344).
19370 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19371 (Fbacktrace_frame): Don't assume nframes fits in int.
19373 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

19378 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19380 * cm.c (calccost): Turn while-do into do-while, for clarity.
19382 * keyboard.c (syms_of_keyboard): Use the same style as later
19383 in this function when indexing through an array. This also
19384 works around GCC bug 48267.
19386 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19388 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19390 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19391 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19393 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19394 This avoids undefined behavior on integer overflow, and is a bit
19395 more convenient anyway since it is compared to a size_t variable.
19397 Variadic C functions now count arguments with size_t, not int.
19398 This avoids an unnecessary limitation on 64-bit machines, which
19399 caused (substring ...) to crash on large vectors (Bug#8344).

19409 * fns.c (concat): Likewise.
19410 * frame.c (x_set_frame_parameters): Likewise.
19411 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19412 0 if not found, not -1. All callers changed.
19414 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19415 (stack_copy_size): Now size_t, not int.
19416 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19418 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19420 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19421 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19422 All callers changed.
19424 * lisp.h (multibyte_char_to_unibyte):
19425 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19426 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19437 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19438 don't set the hook to nil, but remove the offending function instead.
19439 (Qcommand_hook_internal): Remove, unused.
19440 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19441 Vcommand_hook_internal.
19443 * eval.c (enum run_hooks_condition): Remove.
19444 (funcall_nil, funcall_not): New functions.
19445 (run_hook_with_args): Call each function through a `funcall' argument.

19459 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19460 All callers changed.
19462 * w32.c (_wsa_errlist): Use braces for struct initializers.
19464 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

19582 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
19584 * w32term.c (x_set_glyph_string_clipping):
19585 Don't pass uninitialized region to CombineRgn.

19609 2011-03-23 Julien Danjou <julien@danjou.info>
19611 * term.c (Fsuspend_tty, Fresume_tty):
19612 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
19613 * window.c (temp_output_buffer_show):
19614 * insdel.c (signal_before_change):
19615 * frame.c (Fhandle_switch_frame):
19616 * fileio.c (Fdo_auto_save):

19620 * callint.c (Fcall_interactively):
19621 * buffer.c (Fkill_all_local_variables):
19622 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19624 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19625 unconditionally since it does the check itself.
19627 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19629 Fix more problems found by GCC 4.5.2's static checks.
19631 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19632 the first time through the loop, since we know p0 < p1 then.
19633 This also avoids a gcc -Wstrict-overflow warning.
19635 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19636 leading to a memory leak, possible in functions like
19637 load_charset_map_from_file that can allocate an unbounded number
19638 of objects (Bug#8318).
19640 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19641 that could (at least in theory) be that large.
19643 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19644 This is less likely to overflow, and avoids undefined behavior if
19645 overflow does occur. All callers changed. Use strtoul to scan
19646 for the unsigned long integer.
19647 (pint2hrstr): Simplify and tune code slightly.
19648 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
19650 * scroll.c (do_scrolling): Work around GCC bug 48228.
19651 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

19656 This also avoids a warning with gcc -Wstrict-overflow.
19658 * fileio.c (Fcopy_file): Report error if fchown or fchmod
19661 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
19663 * process.c (Fmake_network_process): Use socklen_t, not int,
19664 where POSIX says socklen_t is required in portable programs.
19665 This fixes a porting bug on hosts like 64-bit HP-UX, where
19666 socklen_t is wider than int (Bug#8277).
19667 (Fmake_network_process, server_accept_connection):
19668 (wait_reading_process_output, read_process_output):
19671 * process.c: Rename or move locals to avoid shadowing.

19681 Make tparam.h and terminfo.c consistent.
19682 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19683 Include tparam.h instead, since it declares them.
19684 * cm.h (PC): Remove extern decl; tparam.h now does this.
19685 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19686 * terminfo.c: Include tparam.h, to check interfaces.
19687 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19688 (tparam): Adjust signature to match interface in tparam.h;
19689 this removes some undefined behavior. Check that outstring and len
19690 are zero, which they always are with Emacs.
19691 * tparam.h (PC, BC, UP): New extern decls.
19693 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19694 (xftfont_open): Rename locals to avoid shadowing.
19696 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
19697 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
19698 (OTF_TAG_SYM): Omit macro if not needed.

19706 * xml.c (make_dom): Now static.
19708 * composite.c (composition_compute_stop_pos): Rename local to
19710 (composition_reseat_it): Remove unused locals.
19711 (find_automatic_composition, composition_adjust_point): Likewise.
19712 (composition_update_it): Mark var as initialized.
19713 (find_automatic_composition): Mark vars as initialized,
19714 with a FIXME (Bug#8290).

19717 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
19718 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
19719 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
19720 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19721 to avoid shadowing.
19723 * textprop.c (property_change_between_p): Remove; unused.
19725 * intervals.c (interval_start_pos): Now static.
19727 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

19730 Rename locals to avoid shadowing.
19732 * sound.c (wav_play, au_play, Fplay_sound_internal):
19733 Fix pointer signedness.
19734 (alsa_choose_format): Remove unused local var.
19735 (wav_play): Initialize a variable to 0, to prevent undefined
19736 behavior (Bug#8278).
19738 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
19740 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
19742 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
19743 clobbering (Bug#8298).
19744 * sysdep.c (sys_subshell): Likewise.
19745 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19747 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19748 This should get cleaned up, so that child_setup has the
19749 same signature on all platforms.
19751 * callproc.c (call_process_cleanup): Now static.
19752 (relocate_fd): Rename locals to avoid shadowing.
19754 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19756 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19757 not to be necessary, and produces flickering.
19759 2011-03-20 Glenn Morris <rgm@gnu.org>
19761 * config.in: Remove file.
19763 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
19765 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
19766 are now in src/globals.h.
19767 (syms_of_minibuf): Remove spurious & from previous change.
19769 2011-03-20 Leo Liu <sdl.web@gmail.com>
19771 * minibuf.c (completing-read-function): New variable.
19772 (completing-read-default): Rename from completing-read.
19773 (completing-read): Call completing-read-function.
19775 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
19777 * xfaces.c (Fx_load_color_file):
19778 Read color file from absolute filename (bug#8250).
19780 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
19782 * makefile.w32-in: Update dependencies.
19784 2011-03-17 Eli Zaretskii <eliz@gnu.org>
19786 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

19793 (sigchld_handler): Now static.
19795 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
19796 That way, the code declares only the vars that it needs.
19797 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
19798 * s/cygwin.h (PTY_ITERATION): Likewise.
19799 * s/darwin.h (PTY_ITERATION): Likewise.

19805 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
19806 (CONSTANTLIM): Remove; unused.
19807 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
19808 Define only if needed.
19810 * unexelf.c (unexec): Name an expression,
19811 to avoid gcc -Wbad-function-cast warning.
19812 Use a different way to cause a compilation error if anyone uses
19813 n rather than nn, a way that does not involve shadowing.
19814 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
19816 * deps.mk (unexalpha.o): Remove; unused.
19818 New file unexec.h, the (simple) interface for unexec (Bug#8267).
19819 * unexec.h: New file.
19820 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
19821 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
19822 Depend on unexec.h.
19823 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
19824 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
19825 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
19826 Change as necessary to match prototype in unexec.h.
19828 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
19830 (back_comment, skip_chars): Mark vars as initialized.

19845 (font_sort_entities): Mark var as initialized.
19847 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
19849 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

19881 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
19882 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
19883 some of which prompt warnings from gcc -Wbad-function-cast.
19884 (Fformat_time_string, Fencode_time, Finsert_char):
19885 (Ftranslate_region_internal, Fformat):
19886 Rename or remove local vars to avoid shadowing.
19887 (Ftranslate_region_internal): Mark var as initialized.
19889 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
19892 * lisp.h (eassert): Check that the argument compiles, even if
19893 ENABLE_CHECKING is not defined.
19895 * data.c (Findirect_variable): Name an expression, to avoid
19896 gcc -Wbad-function-cast warning.
19897 (default_value, arithcompare, arith_driver, arith_error): Now static.

19905 Rename locals to avoid shadowing.
19906 (mark_stack): Move local variables into the #ifdef region where
19908 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
19909 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
19911 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
19912 (GC_STRING_CHARS): Remove; not used.
19913 (Fmemory_limit): Cast sbrk's returned value to char *.
19915 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
19916 avoids undefined behavior in theory.

19920 Use functions, not macros, for up- and down-casing (Bug#8254).
19921 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19922 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
19923 to use the following functions instead of these macros.
19924 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19925 EMACS_INT, since callers assume the returned value fits in int.
19926 (upcase1): Likewise, for UPCASE_TABLE.
19927 (uppercasep, lowercasep, upcase): New static inline functions.
19928 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
19929 the race-condition problem in the old DOWNCASE.

19932 Rename locals to avoid shadowing.
19933 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
19934 (regex_compile, re_search_2, re_match_2_internal):
19935 Remove unused local vars.
19936 (FREE_VAR): Rewrite so as not to use empty "else",
19937 which gcc can warn about.
19938 (regex_compile, re_match_2_internal): Mark locals as initialized.
19939 (RETALLOC_IF): Define only if needed.
19940 (WORDCHAR_P): Likewise. This one is never needed, but is used
19941 only in a comment talking about a compiler bug, so put inside
19942 the #if 0 of that comment.
19943 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19944 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
19947 * search.c (boyer_moore): Rename locals to avoid shadowing.
19948 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
19949 (PREV_CHAR_BOUNDARY): Likewise.
19951 * search.c (simple_search): Remove unused var.
19953 * dired.c (compile_pattern): Move decl from here ...

19959 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
19961 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
19962 Rename locals to avoid shadowing.
19963 (Fvertical_motion): Mark locals as initialized.
19965 * casefiddle.c (casify_object, casify_region): Now static.
19966 (casify_region): Mark local as initialized.
19968 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
19970 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
19971 New macros, so that the caller can use some names other than
19972 gcpro1, gcpro2, etc.
19973 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19975 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19976 argument, for consistency with GCPRO2_VAR, etc: it is now the
19977 prefix of the variable, not the variable itself. All uses
19979 * dired.c (directory_files_internal, file_name_completion):
19980 Rename locals to avoid shadowing.
19982 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19983 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19984 dired.c's scmp function, had undefined behavior.
19985 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19986 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19987 * buffer.h: ... to here, because these macros use current_buffer,
19988 and the new implementation with inline functions needs to have
19989 current_buffer in scope now, rather than later when the macros
19991 (downcase, upcase1): New static inline functions.
19992 (DOWNCASE, UPCASE1): Reimplement using these functions.
19993 This avoids undefined behavior in expressions like
19994 DOWNCASE (x) == DOWNCASE (y), which previously suffered
