1 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3 * frame.c (make_frame): Do not set window's buffer to t.
4 * window.c (Fsplit_window_internal): Likewise. Previously it was
5 used to indicate that the window is being set up. Now we use
6 set_window_buffer for all new windows, so the condition in ...
7 (Fset_window_buffer): ... is always true and can be removed.
9 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
11 Convenient macro to check whether the buffer is hidden.
12 * buffer.h (BUFFER_HIDDEN_P): New macro.
13 * frame.c (make_frame): Use it. Adjust comment.
14 * buffer.c (candidate_buffer): New function.
15 (Fother_buffer, other_buffer_safely): Use it.
17 2012-12-06 Eli Zaretskii <eliz@gnu.org>
19 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
20 if the child process is still running. Instead, exit the wait
21 loop and return zero. (Bug#13086)
23 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
25 * frame.h (x_char_width, x_char_height): Remove prototypes.

32 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
33 * keyboard.c (command_loop_1): Remove prototype.
34 (command_loop_2, top_level_1): Add static to match prototype.
36 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
38 Fix a recently-introduced delete-process race condition.
39 * callproc.c, process.h (record_kill_process):
40 New function, containing part of the old call_process_kill.
41 (call_process_kill): Use it.
42 This does not change call_process_kill's behavior.
43 * process.c (Fdelete_process): Use record_kill_process to fix a
44 race condition that could cause Emacs to lose track of a child.
46 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
48 Avoid code duplication between prev_frame and next_frame.
49 * frame.c (candidate_frame): New function. Add comment.
50 (prev_frame, next_frame): Use it. Adjust comment.
52 2012-12-06 Eli Zaretskii <eliz@gnu.org>
54 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
55 fails, signal an error instead of continuing with an empty
57 Encode expanded temp file pattern before passing it to mkstemp or
60 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
61 Encode the file name before passing it to dostounix_filename, in
62 case it will downcase it (under w32-downcase-file-names).
65 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
67 Minor call-process cleanups.
68 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
69 at the same time as other platforms, to simplify analysis.
70 No need for fd0_volatile since we have synch_process_fd.
71 Avoid needless emacs_close; arg is always negative.
73 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
75 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
78 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
80 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
81 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
82 and mouse_face_hidden members to a bitfields.
83 * frame.h (struct frame): Remove set-but-not-used space_width member.
84 (FRAME_SPACE_WIDTH): Remove.
85 * nsterm.m, w32term.c, xterm.c: Adjust users.
86 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
87 member. Adjust users. Convert term_initted, delete_in_insert_mode,
88 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
89 members to a bitfields.
91 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
93 Don't let call-process be a zombie factory (Bug#12980).
94 Fixing this bug required some cleanup of the signal-handling code.
95 As a side effect, this change also fixes a longstanding rare race
96 condition whereby Emacs could mistakenly kill unrelated processes,
97 and it fixes a bug where a second C-g does not kill a recalcitrant
98 synchronous process in GNU/Linux and similar platforms.
99 The patch should also fix the last vestiges of Bug#9488,
100 a bug which has mostly been fixed on the trunk by other changes.
101 * callproc.c, process.h (synch_process_alive, synch_process_death)
102 (synch_process_termsig, sync_process_retcode):
103 Remove. All uses removed, to simplify analysis and so that
104 less consing is done inside critical sections.
105 * callproc.c (call_process_exited): Remove. All uses replaced
106 with !synch_process_pid.
107 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
108 These take the role of what used to be in unwind-protect arg.
110 (block_child_signal, unblock_child_signal):
111 New functions, to avoid races that could kill innocent-victim processes.
112 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
113 (call_process_kill): Record killed processes as deleted, so that
114 zombies do not clutter up the system. Do this inside a critical
115 section, to avoid a race that would allow the clutter.
116 (call_process_cleanup): Fix code so that the second C-g works again
117 on common platforms such as GNU/Linux.
118 (Fcall_process): Create the child process in a critical section,
119 to fix a race condition. If creating an asynchronous process,
120 record it as deleted so that zombies do not clutter up the system.
121 Do unwind-protect for WINDOWSNT too, as that's simpler in the
122 light of these changes. Omit unnecessary call to emacs_close
123 before failure, as the unwind-protect code does that.
124 * callproc.c (call_process_cleanup):
125 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
126 * process.c (record_deleted_pid): New function, containing
127 code refactored out of Fdelete_process.
128 (Fdelete_process): Use it.
129 (process_status_retrieved): Remove. All callers changed to use
131 (record_child_status_change): Remove, folding its contents into ...
132 (handle_child_signal): ... this signal handler. Now, this
133 function is purely a handler for SIGCHLD, and is not called after
134 a synchronous waitpid returns; the synchronous code is moved to
135 wait_for_termination. There is no need to worry about reaping
136 more than one child now.
137 * sysdep.c (get_child_status, child_status_changed): New functions.
138 (wait_for_termination): Now takes int * status and bool
139 interruptible arguments, too. Do not record child status change;
140 that's now the caller's responsibility. All callers changed.
141 Reimplement in terms of get_child_status.
142 (wait_for_termination_1, interruptible_wait_for_termination):
143 Remove. All callers changed to use wait_for_termination.
144 * syswait.h: Include <stdbool.h>, for bool.
145 (record_child_status_change, interruptible_wait_for_termination):
147 (record_deleted_pid, child_status_changed): New decls.
148 (wait_for_termination): Adjust to API changes noted above.
150 * bytecode.c, lisp.h (Qbytecode): Remove.
151 No longer needed after 2012-11-20 interactive-p changes.
153 2012-12-03 Eli Zaretskii <eliz@gnu.org>
155 * xdisp.c (redisplay_window): If the cursor is visible, but inside
156 the scroll margin, move point outside the margin. (Bug#13055)
158 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
160 * gtkutil.c (my_log_handler): New function.
161 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
163 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
165 * lisp.h (modify_region): Rename to...
166 (modify_region_1): ...new prototype.
167 * textprop.c (modify_region): Now static. Adjust users.
168 * insdel.c (modify_region): Rename to...
169 (modify_region_1): ...new function to work with current buffer.
170 Adjust comment and users. Use true and false for booleans.
172 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
174 * alloc.c (free_save_value): New function.
175 (safe_alloca_unwind): Use it.
176 * lisp.h (free_save_value): New prototype.
177 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
179 (save_excursion_restore): Adjust to match saved data structure.
180 Use free_save_value to offload some work from GC. Drop obsolete
183 2012-12-03 Chong Yidong <cyd@gnu.org>
185 * fileio.c (Vauto_save_list_file_name): Doc fix.
187 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
189 * w32fns.c: Remove prototype of atof.
190 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
192 (file_dialog_callback): Declared UINT_PTR.
194 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
197 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
198 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
201 2012-12-03 Glenn Morris <rgm@gnu.org>
203 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
205 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
207 Fix xpalloc confusion after memory is exhausted.
208 * alloc.c (xpalloc): Comment fix.
209 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
210 and signals an error, do not clear charset_table_size, as
211 charset_table is still valid.
212 * doprnt.c (evxprintf): Clear *BUF after freeing it.
214 Use execve to avoid need to munge environ (Bug#13054).
215 * callproc.c (Fcall_process):
216 * process.c (create_process):
217 Don't save and restore environ; no longer needed.
218 * callproc.c (child_setup):
219 Use execve, not execvp, to preserve environ.
221 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
223 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
225 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
227 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
228 display for sliced images (Bug#10500).
230 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
232 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
234 * doc.c (Fdocumentation): Re-add handling of function-documentation,
235 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
237 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
239 * xdisp.c (window_outdated): Remove eassert since it hits
240 some suspicious corner cases (see Bug#13007 and Bug#13012).
241 (mode_line_update_needed): New function.
242 (redisplay_internal, redisplay_window): Use it.
243 (ensure_selected_frame): New function.
244 (redisplay_internal, unwind_redisplay): Use it.
245 (redisplay_internal): Move comment about buffer_shared...
246 (buffer_shared_and_changed): ...near to its real use.
248 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
250 * callproc.c (Fcall_process): Don't misreport vfork failure.
252 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
254 * callproc.c (Fcall_process): Fix vfork portability problems.
255 Do not assume that fd[0], count, filefd, and save_environ survive
256 vfork. Fix bug whereby wrong errno value could be reported for
257 pipe failure. Some minor cleanups, too, as follows. Move buf and
258 bufsize to the context where they're needed. Change new_argv to
259 be of type char **, as this is more convenient and avoids casts.
260 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
261 Now local constants, not macros.
263 2012-11-18 Kenichi Handa <handa@gnu.org>
265 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
266 for the variable "f".
268 2012-11-13 Kenichi Handa <handa@gnu.org>
270 * font.c (font_unparse_xlfd): Exclude special characters from the
271 generating XLFD name.

313 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
314 between bpos_covered and bpos_max. This fixes cursor display when
315 several display strings follow each other.
317 * .gdbinit (pgx): If the glyph's object is a string, display the
318 pointer to string data, rather than the value of the string object
319 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
321 * indent.c (Fvertical_motion): If the starting position is covered
322 by a display string, return to one position before that, to avoid
323 overshooting it inside move_it_to. (Bug#12930)

351 (NAMLEN): Remove, replacing with ...
352 (dirent_namelen): New function. All uses changed. Use the GNU macro
353 _D_EXACT_NAMELEN if available, as it's faster than strlen.
354 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
355 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
356 * makefile.w32-in (DIR_H): Remove. All uses replaced with

376 * nsterm.m (ns_frame_up_to_date): ...but not here.
377 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
379 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

384 * xdisp.c (window_buffer_changed): New function.
385 (update_menu_bar, update_tool_bar): Use it to
386 simplify large 'if' statements.

388 'tail' and 'frame' local variables.
390 2012-11-22 Eli Zaretskii <eliz@gnu.org>

420 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
421 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
422 Define for the MSVC compiler.
424 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
426 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
427 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
428 dostounix_filename. Prevents crashes down the road, because
429 dostounix_filename assumes it gets a unibyte string. Reported by
430 Michel de Ruiter <michel@sentient.nl>, see

479 2012-11-18 Eli Zaretskii <eliz@gnu.org>
481 * w32select.c: Include w32common.h before w32term.h, so that
482 windows.h gets included before w32term.h uses some of its
485 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
487 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
489 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
491 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
493 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
494 (ns_select): Return at once if events are held (Bug#12834).
496 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
498 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
499 Needed following 2012-10-20 change. (Bug#12902)
501 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
503 * w32proc.c (waitpid): Remove unused label get_result.
505 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
507 * makefile.w32-in (SYSWAIT_H): New macro.
508 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
509 ($(BLD)/sysdep.$(O)): Update dependencies.
511 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
513 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
514 * callproc.c (relocate_fd): Assume F_DUPFD.
515 * emacs.c, term.c (O_RDWR): Remove.
516 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
517 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
518 * nsterm.m: Assume <fcntl.h> exists.
519 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
520 (create_pty, Fmake_network_process, server_accept_connection)
521 (wait_reading_process_output, init_process_emacs):
523 (wait_reading_process_output): Put in a special case for WINDOWSNT
524 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
525 It's not clear this is needed, but it's a more-conservative change.
526 (create_process): Assume FD_CLOEXEC.
527 (create_process, create_pty): Assume O_NOCTTY.
528 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
529 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
530 Omit if not DOS_NT, since F_GETFL is not defined there.
531 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
532 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
534 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
535 lack it, since gnulib guarantees this.
536 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
538 2012-11-17 Eli Zaretskii <eliz@gnu.org>
540 * w32.c (faccessat): Pretend that directories have the execute bit
541 set. Emacs expects that, e.g., in files.el:cd-absolute.
543 * w32proc.c (create_child): Don't clip the PID of the child
544 process to fit into an Emacs integer, as this is no longer a
546 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
547 reaping only the process specified by PID argument, if that is
548 positive. Use PID instead of dead_child to know which process to
549 reap. Wait for the child to die only if WNOHANG is not in
551 (sys_select): Don't set dead_child.
553 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
554 as it is no longer needed.
556 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
558 (record_child_status_change): Remove the setting of
559 record_at_most_one_child for the !WNOHANG case.
561 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
563 Fix problems in ns port found by static checking.
564 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
565 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
566 not to process group.
567 (ns_select): Use emacs_write, not write, as that's more robust
568 in the presence of signals.
569 (fd_handler:): Check for read errors.
571 2012-11-16 Glenn Morris <rgm@gnu.org>
573 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
575 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
577 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
579 2012-11-16 Eli Zaretskii <eliz@gnu.org>
581 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
582 use the same value of thread handle.
583 (start_timer_thread): If the timer thread exited (due to error),
584 clean up by closing the two handles it used. Duplicate the caller
585 thread's handle here, so it gets duplicated only once, when
586 launching the timer thread. Set priority of the timer thread, not
588 (getitimer): Don't duplicate the caller thread's handle here.
591 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
593 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
596 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
598 Remove no-longer-used pty_max_bytes variable.
599 * process.c (pty_max_bytes): Remove; unused.
600 (send_process): Do not set it.
602 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
604 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
607 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
609 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
610 This follows up on the 2012-09-29 patch that removed indirection
611 for the 'function' field. Reported by Sergey Vinokurov in
612 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
614 2012-11-14 Eli Zaretskii <eliz@gnu.org>
616 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
617 different name, as the MS runtime does not have such a function,
618 and probably never will.) All callers changed. Ignore DIRFD
619 value if PATH is an absolute file name, to match Posix spec
620 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
623 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
625 * xdisp.c (echo_area_display, redisplay_internal):
626 Omit redundant check whether frame_garbaged is set.
628 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
630 Use faccessat, not access, when checking file permissions (Bug#12632).
631 This fixes a bug that has been present in Emacs since its creation.
632 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
633 which must set some sort of record. (Torek's bug report was against
634 a predecessor of GNU Emacs, but GNU Emacs happened to have the
635 same common flaw.) See Torek's Usenet posting
636 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
637 Posted: Fri Apr 8 14:18:56 1983.
638 * Makefile.in (LIB_EACCESS): New macro.
640 * callproc.c (init_callproc):
641 * charset.c (init_charset):
642 * fileio.c (check_existing, check_executable, check_writable)
644 * lread.c (openp, load_path_check):
645 * process.c (allocate_pty):
647 Use effective UID when checking permissions, not real UID.
648 * callproc.c (init_callproc):
649 * charset.c (init_charset):
650 * lread.c (load_path_check, init_lread):
651 Test whether directories are accessible, not merely whether they exist.
652 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
653 * fileio.c (check_existing, check_executable, check_writable)
655 Use symbolic names instead of integers for the flags, as they're
657 (check_writable): New arg AMODE. All uses changed.
658 Set errno on failure.
659 (Ffile_readable_p): Use faccessat, not stat + open + close.
660 (Ffile_writable_p): No need to call check_existing + check_writable.
661 Just call check_writable and then look at errno. This saves a syscall.
662 dir should never be nil; replace an unnecessary runtime check
663 with an eassert. When checking the parent directory of a nonexistent
664 file, check that the directory is searchable as well as writable, as
665 we can't create files in unsearchable directories.
666 (file_directory_p): New function, which uses 'stat' on most platforms
667 but faccessat with D_OK (for efficiency) if WINDOWSNT.
668 (Ffile_directory_p, Fset_file_times): Use it.
669 (file_accessible_directory_p): New function, which uses a single
670 syscall for efficiency.
671 (Ffile_accessible_directory_p): Use it.
672 * xrdb.c (file_p): Use file_directory_p.
673 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
674 * lread.c (openp): When opening a file, use fstat rather than
675 stat, as that avoids a permissions race. When not opening a file,
676 use file_directory_p rather than stat.
677 (dir_warning): First arg is now a usage string, not a format.
678 Use errno. All uses changed.
679 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
680 that merely introduced a race.
681 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
682 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
683 and similarly for the other O_* flags.
684 * w32.c (sys_faccessat): Rename from sys_access and switch to
685 faccessat's API. All uses changed.
686 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
687 (magic_db): Rename from magic_file_p.
688 (magic_db, search_magic_path): Return an XrmDatabase rather than a
689 char *, so that we don't have to test for file existence
690 separately from opening the file for reading. This removes a race
691 fixes a permission-checking problem, and simplifies the code.
693 (file_p): Remove; no longer needed.
695 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
697 Omit glyphs initialization at startup.
698 * dispnew.c (glyphs_initialized_initially_p): Remove.
699 (adjust_frame_glyphs_initially): Likewise. Adjust users.
700 (Fredraw_frame): Move actual code from here...
701 (redraw_frame): ...to here. Add eassert. Adjust comment.
702 (Fredraw_display): Use redraw_frame.
703 * xdisp.c (clear_garbaged_frames): Likewise.
705 2012-11-13 Eli Zaretskii <eliz@gnu.org>
707 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
708 passed to pint2str and pint2hrstr to be at most the size of the
709 frame's decode_mode_spec_buffer. This avoids crashes with very
710 large values of FIELD_WIDTH argument to decode_mode_spec.
713 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
715 Fix a race with verify-visited-file-modtime (Bug#12863).
716 Since at least 1991 Emacs has ignored an mtime difference of no
717 more than one second, but my guess is that this was to work around
718 file system bugs that were fixed long ago. Since the race is
719 causing problems now, let's remove that code.
720 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
721 whose time stamp is off by no more than a second. Insist that the
722 file time stamps match exactly.
724 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
726 * frame.h (struct frame): Convert external_tool_bar member to
727 1-bit unsigned bitfield.
728 * termhooks.h (struct terminal): Remove mouse_moved member since
729 all users are long dead. Adjust comment on mouse_position_hook.
731 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
733 Simplify by using FOR_EACH_FRAME here and there.
734 * frame.c (next_frame, prev_frame, other_visible_frames)
735 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
736 * w32term.c (x_window_to_scroll_bar): Likewise.
737 * window.c (window_list): Likewise.
738 * xdisp.c (x_consider_frame_title): Likewise.
739 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
740 * xfns.c (x_window_to_frame, x_any_window_to_frame)
741 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
742 * xmenu.c (menubar_id_to_frame): Likewise.
743 * xselect.c (frame_for_x_selection): Likewise.
744 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
745 (x_window_to_menu_bar): Likewise.
746 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
748 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
750 * data.c (Qdefalias_fset_function): Now static.
752 Another tweak to vectorlike_header change.
753 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
754 Remove, and replace all uses with ...
755 (next_in_free_list, set_next_in_free_list):
756 New functions, which respect C's aliasing rules better.
758 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
760 * window.c (list4i): Rename from 'quad'. All uses changed.
761 Needed because <sys/types.h> defines 'quad' on Solaris 10.
763 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
765 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
766 warning about mixing declarations and code in ISO C90.
768 2012-11-10 Martin Rudalics <rudalics@gmx.at>
770 * window.c (Fsplit_window_internal): Set combination limit of
771 new parent window to t iff Vwindow_combination_limit is t;
772 fixing a regression introduced with the change from 2012-09-22.
773 (Fset_window_combination_limit): Fix doc-string.
775 2012-11-10 Eli Zaretskii <eliz@gnu.org>
777 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
778 amount when the scroll margins are too large. When scrolling
779 backwards in the buffer, give up if cannot reach point or the
780 scroll margin within a reasonable number of screen lines.
781 Fixes point position in window under scroll-up/down-aggressively when
782 point is positioned many lines beyond the window top/bottom.
785 * ralloc.c (relinquish): If real_morecore fails to return memory
786 to the system, don't crash; instead, leave the last heap
787 unchanged and return. (Bug#12774)
789 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
791 * lisp.h (AUTOLOADP): New macro.
792 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
793 * data.c (Ffset): Remove special ad-advice-info handling.
794 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
796 (Finteractive_form): Simplify.
797 (Fquo): Don't insist on having at least 2 arguments.
798 (Qdefalias_fset_function): New var.
800 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
802 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
804 * nsfont.m (Qcondensed, Qexpanded): New variables.
805 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
806 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
808 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
810 Fix recently introduced crash on MS-Windows (Bug#12839).
811 * w32term.h (struct scroll_bar): Use convenient header.
812 (SCROLL_BAR_VEC_SIZE): Remove.
813 * w32term.c (x_scroll_bar_create): Use VECSIZE.
815 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
817 Tweak last vectorlike_header change.
818 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
819 vectorlike object on the free list. This is introduced to avoid
820 some (but not all) pointer casting and aliasing problems, see
821 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
822 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
824 (xvectype, xvecsize): Use them to examine Lisp_Object values.
826 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
828 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
829 been removed, so remove them here also.
831 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
833 * doc.c (Fdocumentation): Handle new property
834 dynamic-docstring-function to replace the old ad-advice-info.
836 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
838 * fns.c (Qeql, hashtest_eq): Now static.
840 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
842 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
843 * fns.c (hashfn_eq, hashfn_eql, sxhash):
844 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
845 * buffer.c (compare_overlays): Use XLI rather than XHASH.
847 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
849 Use same hash function for hashfn_profiler as for hash_string etc.
850 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
851 * lisp.h (sxhash_combine): New inline function, with the contents
852 of the old SXHASH_COMBINE.
853 * profiler.c (hashfn_profiler): Use it, instead of having a
854 special hash function containing a comparison that always yields 1.
856 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
858 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
859 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)

863 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
865 * image.c (xpm_make_color_table_h): Fix compiler error because
866 make_hash_table changed.
868 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
870 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
872 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
874 Use ad-hoc comparison function for the profiler's hash-tables.
875 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
876 (make_log): Use them.
877 (handle_profiler_signal): Don't inhibit quit any longer since we don't
878 call Fequal any more.
879 (Ffunction_equal): New function.
880 (cmpfn_profiler, hashfn_profiler): New functions.
881 (syms_of_profiler): Initialize them.

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

891 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
892 (syms_of_fns): Initialize them.

901 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
902 value of w32-scroll-lock-modifier is neither nil nor one of the
903 known key modifiers. (Bug#12806)
905 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
907 Shrink struct vectorlike_header to the only size field.
908 * lisp.h (enum pvec_type): Avoid explicit enum member values.
910 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
911 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
912 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
913 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
914 information from the vector header. Adjust comment.

929 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
930 (large_vectors): Change type to struct large_vector.
931 (allocate_vector_from_block): Simplify.
932 (PSEUDOVECTOR_NBYTES): Replace with...
933 (vector_nbytes): ...new function. Adjust users.
934 (sweep_vectors): Adjust processing of large vectors.
935 (allocate_vectorlike): Likewise.
936 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
937 Add easserts. Adjust XSETPVECTYPESIZE usage.
938 (allocate_buffer): Use BUFFER_PVEC_INIT.
939 (live_vector_p): Adjust to match large vector.
940 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
941 * buffer.h (struct buffer): Add next member.
942 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):

950 (xvecsize): New command.
952 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
954 * keyboard.c (event_to_kboard): Do not dereference
955 frame_or_window field of SELECTION_REQUEST_EVENT
956 and SELECTION_CLEAR_EVENT events (Bug#12814).
957 * xterm.h (struct selection_input_event): Adjust comment.
959 2012-11-07 Eli Zaretskii <eliz@gnu.org>
961 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
962 such as Scroll Lock, if the respective keys are treated as
963 function keys, not as modifiers. This avoids destroying non-ASCII
964 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
966 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
968 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
970 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
972 Restore some duplicate definitions (Bug#12814).
973 This undoes part of the 2012-11-03 changes. Some people build
974 with plain -g rather than with -g3, and they need the duplicate
975 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
976 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
977 Define as macros, as well as as enums or as constants.
979 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
981 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
982 to keypad keys (Bug#12816).
984 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
986 Minor adjustments of recently-changed frame functions.
987 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
988 known to be a frame (we're in the FRAMEP branch).
989 * lisp.h (Qframep): Remove decl. frame.h declares this.
990 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
991 since they're meant for Lisp fixnum values.
993 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
995 * window.c (Fwindow_combination_limit): Revert to the only
996 required argument and adjust docstring as suggested in
997 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
998 by Martin Rudalics <rudalics@gmx.at>.
1000 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1002 Widely used frame validity and checking functions.
1003 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1004 * frame.c (decode_live_frame, decode_any_frame): New functions.
1005 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1006 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1007 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1008 (Fframe_pointer_visible_p): Use decode_any_frame.
1009 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
1010 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1011 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1012 (Fframe_focus): Likewise. Allow zero number of arguments.
1014 (frame_buffer_list, frame_buffer_predicate): Remove.
1015 * lisp.h (frame_buffer_predicate): Remove prototype.
1016 * buffer.c (Fother_buffer): Use decode_any_frame.
1017 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1018 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1019 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1020 (Fclose_font, Ffont_info): Use decode_live_frame.
1021 * fontset.c (check_fontset_name): Likewise.
1022 * terminal.c (Fframe_terminal): Likewise.
1023 * w32fns.c (check_x_frame): Likewise.
1024 * window.c (Fminibuffer_window, Fwindow_at)
1025 (Fcurrent_window_configuration): Likewise.
1026 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1027 Likewise. Allow zero number of arguments. Adjust docstring.
1028 * dispnew.c (Fredraw_frame): Likewise.
1029 * xfaces.c (frame_or_selected_frame): Remove.
1030 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1031 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1032 (Fframe_face_alist): Use decode_live_frame.
1033 * xfns.c (check_x_frame): Likewise.
1035 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1037 * window.c (quad): New function.
1038 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1039 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1040 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1041 (Fwindow_line_height): Use it.
1042 (Fwindow_fringes): Use list3.
1043 (Fwindow_scroll_bars): Use list4.
1044 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1045 (Fwindow_combination_limit): Allow zero number of arguments.
1047 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1049 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1051 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1052 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1053 file descriptor 2 for standard error. (Bug#12805)
1055 2012-11-05 Chong Yidong <cyd@gnu.org>
1057 * process.c (wait_reading_process_output): Revert previous change.
1059 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1061 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1062 This removes code that has been obsolete since around 1990.
1063 * callproc.c (Fcall_process):
1065 * process.c (create_process):
1066 * term.c (dissociate_if_controlling_tty):
1067 Assume setsid exists.
1068 * callproc.c (child_setup): Assume setpgid exists and behaves as
1069 per POSIX.1-1988 or later.
1070 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1071 * emacs.c (shut_down_emacs):
1072 * sysdep.c (sys_suspend, init_foreground_group):
1073 Assume getpgrp behaves as per POSIX.1-1998 or later.
1074 * msdos.c (setpgrp): Remove.
1075 (tcgetpgrp, setpgid, setsid): New functions.
1076 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1077 * term.c (no_controlling_tty): Remove; unused.
1078 * w32proc.c (setpgrp): Remove.
1079 (setsid, tcgetpgrp): New functions.
1081 Simplify by assuming __fpending.
1082 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1083 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1084 Do not assume that __fpending's result fits in int.
1086 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1088 Remove EMACS_OUTQSIZE+sleep hack.
1089 * dispnew.c (update_frame_1): Remove hack for terminals slower
1090 than 2400 bps, which throttled Emacs by having it sleep.
1091 This code hasn't worked since at least 2007, when the multi-tty stuff
1092 was added, and anyway those old terminals are long dead.
1093 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1094 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1096 Fix data-loss with --version (Bug#9574).
1097 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1098 as we can't assume that emacs_strerror is initialized, and strerror
1099 is good enough here.
1100 (main): Invoke atexit earlier, to catch earlier instances of
1101 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1103 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1105 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1106 (keyDown): Remap keypad keys to X11 virtual key codes.
1108 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1110 Fix data-loss with --batch (Bug#9574).
1111 * emacs.c: Include <close-stream.h>.
1112 (close_output_streams): New function.
1113 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1114 and handles errors appropriately.
1115 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1118 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1119 The symptom is a diagnostic "GLib-WARNING **: In call to
1120 g_spawn_sync(), exit status of a child process was requested but
1121 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1122 waitpid(), so exit status can't be returned." The diagnostic
1123 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1124 The real bug is a race condition between Emacs and glib: Emacs
1125 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1126 so that glib can't find it. Work around the bug by invoking
1127 waitpid only on subprocesses that Emacs itself creates.
1128 * process.c (create_process, record_child_status_change):
1129 Don't use special value -1 in pid field, as the caller now must
1130 know the pid rather than having the callee infer it.
1131 The inference was sometimes incorrect anyway, due to another race.
1132 (create_process): Set new 'alive' member if child is created.
1133 (process_status_retrieved): New function.
1134 (record_child_status_change): Use it.
1135 Accept negative 1st argument, which means to wait for the
1136 processes that Emacs already knows about. Move special-case code
1137 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1138 processes that have already been waited for, by testing and
1139 clearing new 'alive' member.
1140 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1141 now does this internally.
1142 (handle_child_signal): Let record_child_status_change do all
1143 the work, since we do not want to reap all exited child processes,
1144 only the child processes that Emacs itself created.
1145 * process.h (Lisp_Process): New boolean member 'alive'.
1147 Omit duplicate definitions no longer needed with gcc -g3.
1148 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1149 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1150 Define only as macros. There's no longer any need to also define
1151 these symbols as enums or as constants, since we now assume
1152 gcc -g3 when debugging.
1154 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1156 * lisp.mk: Adjust comments to the fact that term/internal is now
1157 loaded from loadup.el.
1159 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1160 (msdos_fatal_signal): New function.
1161 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1164 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1165 for GCC versions before 4.
1166 (emacs_raise): Define to call msdos_fatal_signal.
1168 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1169 iterator when starting in the middle of a display or overlay
1172 2012-11-03 Chong Yidong <cyd@gnu.org>
1174 * process.c (wait_reading_process_output): Clean up the last
1177 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1179 * process.c (wait_reading_process_output): Avoid a race condition
1180 with SIGIO delivery (Bug#11536).
1182 2012-11-03 Chong Yidong <cyd@gnu.org>
1184 * buffer.c (cursor_type): Untabify docstring.
1186 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1188 * frame.h (struct frame): Drop can_have_scroll_bars member
1189 which is meaningless for a long time. Adjust comments.
1190 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1191 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1193 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1195 * window.c (decode_next_window_args): Update window arg after
1196 calling decode_live_window and so fix crash reported at
1197 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1198 by Juanma Barranquero <lekktu@gmail.com>.
1199 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1200 * font.c (Ffont_at): Likewise.
1202 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1204 * widget.c (resize_cb): New function.
1205 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1206 (EmacsFrameResize): Check if all is up to date before changing frame
1209 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1211 Implement backtrace output for fatal errors on MS-Windows.
1212 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1213 (BACKTRACE_LIMIT_MAX): New macro.
1214 (w32_backtrace): New function.
1215 (emacs_abort): Use w32_backtrace when the user chooses not to
1216 attach a debugger. Update the text of the abort dialog.
1218 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1220 Window-related stuff cleanup here and there.
1221 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1222 Use decode_any_window.
1223 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1224 * xdisp.c (Fformat_mode_line): Likewise.
1225 * font.c (Ffont_at): Use decode_live_window.
1226 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1227 * window.c (decode_next_window_args): Likewise.
1228 (decode_any_window): Remove static.
1229 * window.h (decode_any_window): Add prototype.
1230 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1231 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1234 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1236 Remove pad from struct input_event.
1237 * termhooks.h (struct input_event): Remove padding field.
1239 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1240 member is never cons for a long time. Adjust comment.
1241 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1242 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1243 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1244 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1246 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1248 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1250 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1252 Fix crash when using Emacs as commit editor for git (Bug#12697).
1253 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1254 and it is configured in conf_post.h.
1255 (Fcall_process): Don't invoke both setsid and setpgid; the former
1256 is enough, if it exists.
1257 * callproc.c (Fcall_process, child_setup):
1258 * process.c (create_process): Use setpgid.
1259 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1261 * dispnew.c (init_display): Initialize the foreground group
1262 if we are running a tty display.
1263 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1264 * lisp.h (init_foreground_group): New decl.
1265 * sysdep.c (inherited_pgroup): New static var.
1266 (init_foreground_group, tcsetpgrp_without_stopping)
1267 (narrow_foreground_group, widen_foreground_group): New functions.
1268 (init_sys_modes): Narrow foreground group.
1269 (reset_sys_modes): Widen foreground group.
1271 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1273 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1275 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1277 * minibuf.c (read_minibuf): Restore current buffer since
1278 choose_minibuf_frame calling Fset_frame_selected_window may
1279 change it (Bug#12766).
1281 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1283 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1285 2012-10-30 Kenichi Handa <handa@gnu.org>
1287 * font.c (Ffont_at): If WINDOW is specified and it is not
1288 displaying the current buffer, signal an error.
1290 2012-10-29 Daniel Colascione <dancol@dancol.org>
1292 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1293 In preparation for fixing bug#12739, move these functions from
1296 * coding.h, coding.c: ... to here, and compile them only when
1297 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1298 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1300 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1302 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1303 (timer_loop, getitimer, setitimer): Use it instead of
1304 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1306 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1309 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1311 * nsterm.m (NO_APPDEFINED_DATA): New define.
1312 (last_appdefined_event_data): New variable
1313 (last_appdefined_event): Remove.
1314 (ns_select): Initialize t from last_appdefined_event_data instead
1315 of [last_appdefined_event data1].
1316 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1317 remove last_appdefined_event (Bug#12698).
1319 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1321 * frame.c (x_set_font): Catch internal error.
1323 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1325 Avoid overflow in w32 implementation of interval timers.
1326 When possible, for ITIMER_PROF count only times the main thread
1328 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1329 'volatile ULONGLONG' types. All the other data which was
1330 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1331 (GetThreadTimes_Proc): New typedef.
1332 (w32_get_timer_time): New function, returns a suitable time value
1334 (timer_loop): Enter critical section when accessing ULONGLONG
1335 values of the itimer_data struct, as these accesses are no longer
1336 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1337 Remove unused variable.
1338 (init_timers): Initialize s_pfn_Get_Thread_Times.
1339 (start_timer_thread): Don't assign itimer->caller_thread here.
1340 (getitimer): Assign itimer->caller_thread here.
1341 (setitimer): Always call getitimer to get the value of ticks_now.
1342 (sys_spawnve): Avoid compiler warning about format mismatch.
1344 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1346 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1347 mouse movement events if the menu bar is active. This avoids
1348 producing a busy "hour-glass" cursor by Windows if the mouse
1349 pointer is positioned over a tooltip shown for some menu item.
1351 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1353 Don't assume process IDs fit in int.
1354 * emacs.c (shut_down_emacs) [!DOS_NT]:
1355 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1356 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1357 Use pid_t, not int, to store process IDs, as 'int'
1358 is not wide enough on a few platforms (e.g., AIX and IRIX).
1360 2012-10-23 Kenichi Handa <handa@gnu.org>
1362 The following change is to make face-font-rescale-alist work
1363 correctly for non-ASCII fonts.
1365 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1366 (font_open_for_lface): Handle Vface_font_rescale_alist.
1368 2012-10-23 Chong Yidong <cyd@gnu.org>
1370 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1372 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1374 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1376 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1378 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1381 2012-10-21 Glenn Morris <rgm@gnu.org>
1383 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1385 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1387 Port to OpenBSD 5.1.
1388 * frame.c (Fmouse_position, Fmouse_pixel_position):
1389 * xdisp.c (produce_stretch_glyph):
1390 Declare local vars only when they're needed.
1391 This is clearer and avoids a warning on OpenBSD about unused vars.
1392 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1393 This is safer, and avoids OpenBSD warnings about unused vars.
1394 * keyboard.c (record_menu_key): Remove unnecessary decl.
1395 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1396 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1397 as our definition clashes with OpenBSD's.

1873 now a supported configuration.
1875 * Makefile.in: consolidate image variables into LIBIMAGE; add
1876 W32_OBJ and W32_LIBS. Compile new files.
1879 (_DebPrint) declare tracing facility for W32 debugging. We need
1880 to unify tracing later.
1882 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1883 unconditional use of W32 Unicode functions. Cygwin runs only on
1884 100% Unicode operating systems.
1886 * cygw32.c: New file. Define Cygwin-specific facilities.
1887 (Fcygwin_convert_path_to_windows)
1888 (Fcygwin_convert_path_from_windows): New user functions for
1889 accessing Cygwin path-munging routines.
1891 * cygw32.h: New file.
1892 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1893 UTF-16LE strings temporarily inside non-Lisp-visible string
1896 (w32_strerror): Just what it says on the tin.
1898 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1899 also run for Cygwin; both systems have the same problem with using
1900 GUI facilities in a forked child. Also call syms_of_cygw32,
1901 syms_of_w32select in correct places.
1903 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1904 needs fork-then-exec for daemon launching.
1906 * font.h: Include frame.h.
1908 * image.c: Use the image library cache machinery only when we're
1909 compiling for native WINDOWSNT; Cygwin can use shared libraries
1910 like any other Unixlike system.
1912 * keyboard.c: Clarify a comment regarding the input loop.
1914 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1915 functions directly instead of trying to detect at runtime that our
1916 host operating system supports them. We make this change for two
1917 reasons: Cygwin lacks support for the multibyte character
1918 conversion functions used by the legacy menu code, and Cygwin
1919 never needs to rely on non-Unicode APIs.
1921 * unexw32.c (hinst): Declare extern.
1923 * w32.c: Change header order;
1924 (w32_strerror): Move to w32fns.c because we need it for
1925 non-WINDOWSNT builds.
1927 * w32.h: Add #error macro to make sure we don't include w32.h for
1928 Cygwin builds. Remove w32select declarations.
1930 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1931 w32fns.c. w32console.c is WINDOWSNT-only.
1933 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1934 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1936 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1937 (w32_major_version, w32_minor_version, w32_build_number)
1938 (os_subtype, sound_type): Define here
1939 (w32_defined_color): Make color parameter const for consistency
1940 with other _defined_color functions.
1941 (w32_createwindow): Unconditionally call w32_init_class instead of
1942 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1943 through the code is complex and unnecessary because class
1944 registration is practically free.
1945 (w32_name_of_message): New EMACSDEBUG-only function.
1946 (Fset_message_beep): Move here
1947 (Fx_open_connection): Require that the display name for Windows be
1948 "w32" for consistency, emacsclient disambiguation, and maybe, one
1949 day, multi-window-system support.
1950 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1951 Cygwin files for W32 GUI facilities, since these clearly don't
1952 expect Cygwin names.
1953 (_DebPrint): Define.
1954 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1955 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1956 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1957 (w32_last_error): Remove.
1959 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1961 * w32heap.c (syspage_mask): Declare here.
1962 (cache_system_info): Remove.
1964 * w32inevt.c (faked_key): Define globally, not statically.
1965 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1966 (w32_console_toggle_lock_key): Move to w32fns.c.
1968 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1970 * w32proc.c (_DebPrint): Move to w32fns.c.
1971 * w32select.c: Include string.h, stdio.h for Cygwin.
1972 * w32select.h: New File.
1974 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1976 (w32_message_fd): New variable. Under Cygwin, holds the file
1977 descriptor the system used to tell us about pending thread
1980 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1981 that prevented compilation under non-WINDOWSNT systems.
1983 (w32_initialize): Open /dev/windows and assign it to
1984 w32_message_fd. Provide w32 feature.
1986 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1987 (WM_EMACS_INPUT_READY): add.
1988 (prepend_msg, w32_message_fd): Declare globally.
1991 (keyboard_handle): Use only when WINDOWSNT.
1992 (notify_msg_ready): New function. Posts a message to the main
1993 thread's message queue under CYGWIN, which wakes up the main
1994 thread from select(2) by making the /dev/windows file descriptor
1995 ready. Under WINDOWSNT, it sets an event the same way the old
1998 (post, prepend_msg): Actually call notify_msg_ready instead of
1999 setting the input event directly.
2001 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2003 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2004 but it still has blocs in it, don't return it to the system,
2005 instead of aborting. (Bug#12402)
2007 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2009 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2011 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2012 MAC_OS_X_VERSION_10_6.
2013 (syms_of_nsterm): Remove comment about Panther and above for
2015 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2016 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2017 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2019 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2020 MAC_OS_X_VERSION_10_4.
2022 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2023 MAC_OS_X_VERSION_10_2.
2025 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2027 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2028 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2030 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2031 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2032 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2033 Remove ns_in_resize check.
2034 (ns_clear_frame_area): Remove resize handle code.
2036 * nsfns.m (ns_in_resize): Remove.
2037 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2038 Remove ns_in_resize check.
2040 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2042 Improve sys_siglist detection.
2043 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2044 defined as a macro, as is done in Solaris.
2045 (sys_siglist_entries): New macro.
2046 (save_strsignal): Use it.
2047 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2048 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2050 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2052 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2053 fullscreen/Fullscreen.
2055 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2056 tobar_height is new.
2058 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2059 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2060 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2061 (windowDidResize:): Check for correct window if old style fullscreen.
2062 Capitalize word in comment. Remove incorrect comment.
2063 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2064 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2065 error in drawing background.
2066 (toggleFullScreen:): Remove comment. Rearrange calls.
2067 Set toolbar values to zero, save old height in tobar_height.
2068 Restore tool bar height when leaving fullscreen.
2069 (canBecomeMainWindow): New function.
2071 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2073 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2075 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2077 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2079 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2080 that time stamps of directories could also be changed.
2081 Don't request the too broad GENERIC_WRITE, only the more restrictive
2082 FILE_WRITE_ATTRIBUTES access rights.
2084 * fileio.c (Fset_file_times): Special-case ignoring errors for
2085 directories only on MSDOS, not on MS-Windows.
2087 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2089 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2091 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2093 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2094 see whether CreateFile failed.
2096 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2098 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2099 to avoid similar races.
2100 * keyboard.c (pending_signals): Now bool, not int.
2102 Port timers to OpenBSD, plus check for timer failures.
2103 OpenBSD problem reported by Han Boetes.
2104 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2106 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2107 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2108 like OpenBSD, which has timer_settime but does not declare it.
2109 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2110 whether to use itimerspec-related primitives. All uses of
2111 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2113 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2115 * profiler.c (handle_profiler_signal): Fix a malloc race
2116 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2118 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2120 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2122 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2124 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2125 consistent with the change in return value of 'safe_strsignal'.
2127 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2129 Prefer plain 'static' to 'static inline' (Bug#12541).
2130 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2131 (bidi_set_sor_type, bidi_push_embedding_level)
2132 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2133 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2134 (bidi_cache_search, bidi_cache_ensure_space)
2135 (bidi_cache_iterator_state, bidi_cache_find)
2136 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2137 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2138 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2139 Now 'static', not 'static inline'.
2141 Count overruns when profiling; change units to ns.
2142 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2143 Give extra weight to samples after overruns, to attempt to count
2144 the time more accurately.
2145 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2146 the underlying primitives nominally do ns.
2147 (Fprofiler_cpu_start): Document the change. Mention that
2148 the sampling intervals are only approximate.
2150 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2152 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2154 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2155 case for the special 0 coding-system.
2157 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2158 (Fmake_overlay): Remove redundant tests.
2159 (fix_start_end_in_overlays): Remove redundant recentering.
2161 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2163 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2164 Update dependencies.
2166 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2168 Fix a malloc race condition involving strsignal.
2169 A signal can arrive in the middle of a malloc, and Emacs's signal
2170 handler can invoke strsignal, which can invoke malloc, which is
2171 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2172 Fix it by altering the signal handler so that it does not invoke
2174 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2175 * process.c (status_message): Use const pointer, in case strsignal
2176 is #defined to safe_strsignal.
2177 * sysdep.c (sys_siglist, init_signals): Always define and
2178 initialize a substitute sys_siglist if the system does not define
2179 one, even if HAVE_STRSIGNAL.
2180 (safe_strsignal): Rename from strsignal. Always define,
2181 using sys_siglist. Return a const pointer.
2182 * syssignal.h (safe_strsignal): New decl.
2183 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2185 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2187 * w32proc.c (timer_loop): Fix code that waits for timer
2188 expiration, to avoid high CPU usage.
2190 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2192 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2193 (sweep_weak_table): Remove redundant prototypes.
2195 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2197 * emacs.c: Move the inclusion of TERM_HEADER after including
2198 windows.h on WINDOWSNT. This avoids compilation problems with
2201 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2203 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2204 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2205 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2206 as the previous version used 'void *'.
2208 * ralloc.c (ROUNDUP): Fix last change.
2209 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2212 * w32proc.c <disable_itimers>: New static flag.
2213 (init_timers): Initialize it to zero, after creating the critical
2214 sections used by the timer threads.
2215 (term_timers): Set to 1 before deleting the critical sections.
2216 (getitimer, setitimer): If disable_itimers is non-zero, return an
2217 error indication without doing anything. Reported by Fabrice
2218 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2219 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2221 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2224 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2225 term_ntproc after all the other bookkeeping, to get timers working
2226 as long as possible.
2228 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2230 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2231 Suggested by Juri Linkov in
2232 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2234 Prefer plain 'static' to 'static inline' (Bug#12541).
2235 With static functions, modern compilers inline pretty well by
2236 themselves; advice from programmers often hurts as much as it helps.
2237 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2238 this change shrinks the text size of the Emacs executable by 1.1%
2239 without affecting CPU significantly in my benchmark.

2325 * dired.c (directory_files_internal, Ffile_attributes):
2328 * frame.c (x_report_frame_params): Port better to wider ints.
2329 Do not assume that EMACS_UINT is the same width as uprintmax_t,

2533 (handle_profiler_signal): Rename from sigprof_handler_1,
2534 for consistency with other handlers. Do not check whether
2535 cpu_log is a hash-table if garbage collecting, since it

2538 for consistency with other handlers.
2539 (setup_cpu_timer): New function, with much of what used to be in

2541 Prefer timer_settime if available, and prefer
2542 thread cputime clocks, then process cputime clocks, then
2543 monotonic clocks, to the old realtime clock. Use make_timeval
2544 to round more-correctly when falling back to setitimer.
2545 (Fprofiler_cpu_start): Use it.
2546 (Fprofiler_cpu_stop): Prefer timer_settime if available.

2553 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2554 in profiler.c, since sysdep.c now uses it.
2556 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

2612 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2613 Since this stuff is now private to charset.c, there's no need for
2614 a public macro and no need to inline by hand.

2694 install term_ntproc as a signal handler for SIGABRT, as that
2695 should be done by the dumped Emacs.

2797 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2799 * makefile.w32-in (BLOCKINPUT_H): Remove.

2816 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2818 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2819 fatal_error_backtrace.
2821 * w32proc.c (sys_kill): Undo last change: don't do anything when
2822 invoked to deliver SIGABRT to our own process. This is now
2823 handled by emacs_raise.
2825 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2827 * w32term.c (w32_read_socket): Remove leftover reference to
2828 interrupt_input_pending.
2830 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2832 Do not use SA_NODEFER.
2833 Problem reported by Dani Moncayo in
2834 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2836 * sysdep.c (emacs_abort): Do not reset signal handler.
2837 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2838 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2839 wanted even on POSIXish hosts, and it doesn't work on Windows.
2841 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2843 * xterm.c (x_term_init): Call fixup_locale before and after calling
2844 gtk_init (Bug#12392).
2846 2012-09-23 Chong Yidong <cyd@gnu.org>
2848 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2849 Vdynamic_library_alist.
2851 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2852 (Fgnutls_available_p): Caller changed.
2854 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2855 (Flibxml_parse_xml_region): Likewise.
2857 * dispextern.h (struct image_type): Remove arg from init function.
2859 * image.c (Finit_image_library, lookup_image_type)
2860 (define_image_type): Remove now-unneeded second arg.
2861 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2862 (init_tiff_functions, init_gif_functions, init_svg_functions):
2863 Arglist and w32_delayed_load calling convention changed.
2864 (gs_type): Remove init_gs_functions; there is no such function.
2865 (valid_image_p, make_image): Fix caller to lookup_image_type.
2867 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2869 Simplify and avoid signal-handling races (Bug#12471).
2871 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2872 Avoid recursive loop if there's a fatal error in the function itself.
2873 * atimer.c (pending_atimers):
2874 * blockinput.h: Don't include "atimer.h"; no longer needed.
2875 (interrupt_input_pending): Remove. All uses removed.
2876 pending_signals now counts both atimers and ordinary interrupts.
2877 This is less racy than having three separate pending-signal flags.
2878 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2880 Rename from their upper-case counterparts BLOCK_INPUT,
2881 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2882 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2883 This makes it easier to access volatile variables more accurately.
2884 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2885 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2886 that's more reliable if the code is buggy and sets
2887 interrupt_input_blocked to a negative value. All uses changed.
2888 * atimer.c (deliver_alarm_signal):
2889 Remove. No need to deliver this to the parent; any thread can
2890 handle this signal now. All uses replaced by underlying handler.
2891 * atimer.c (turn_on_atimers):
2892 * dispnew.c (handle_window_change_signal):
2893 * emacs.c (handle_danger_signal):
2894 * keyboard.c (kbd_buffer_get_event):
2895 Don't reestablish signal handler; not needed with sigaction.
2896 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2898 Rework to avoid unnecessary accesses to volatile variables.
2899 (UNBLOCK_INPUT_TO): Now a function.
2900 (totally_unblock_input, unblock_input): New decls.
2901 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2902 (init_data): Remove. Necessary stuff now done in init_signal.
2903 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2904 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2905 (fatal_error_code): Remove; no longer needed.
2906 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2907 it doesn't always backtrace. All uses changed. No need to reset
2908 signal to default, since sigaction and/or die does that for us now.
2909 Use emacs_raise (FOO), not kill (getpid (), FOO).
2910 (main): Check more-accurately whether we're dumping.
2911 Move fatal-error setup to sysdep.c
2912 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2913 * gtkutil.c (xg_get_file_name, xg_get_font):
2914 Remove no-longer-needed signal-mask manipulation.
2915 * keyboard.c, process.c (POLL_FOR_INPUT):
2916 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2917 * keyboard.c (read_avail_input): Remove.
2918 All uses replaced by gobble_input.
2919 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2920 (kbd_buffer_store_event_hold, gobble_input):
2921 (record_asynch_buffer_change) [USABLE_SIGIO]:
2922 (store_user_signal_events):
2923 No need to mess with signal mask.
2924 (gobble_input): If blocking input and there are terminals, simply
2925 set pending_signals to 1 and return. All hooks changed to not
2926 worry about whether input is blocked.
2927 (process_pending_signals): Clear pending_signals before processing
2928 them, in case a signal comes in while we're processing.
2929 By convention callers now test pending_signals before calling us.
2930 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2931 New functions, to support changes to blockinput.h.
2932 (handle_input_available_signal): Now extern.
2933 (reinvoke_input_signal): Remove. All uses replaced by
2935 (quit_count): Now volatile, since a signal handler uses it.
2936 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2937 All callers changed. Block SIGINT only if not already blocked.
2938 Clear sigmask reliably, even if Fsignal returns, which it can.
2939 Omit unnecessary accesses to volatile var.
2940 (quit_throw_to_read_char): No need to restore sigmask.
2941 * keyboard.c (gobble_input, handle_user_signal):
2942 * process.c (wait_reading_process_output):
2943 Call signal-handling code rather than killing ourselves.
2944 * lisp.h: Include <float.h>, for...
2945 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2946 (pending_signals): Now volatile.
2947 (syms_of_data): Now const if IEEE floating point.
2948 (handle_input_available_signal) [USABLE_SIGIO]:
2949 (terminate_due_to_signal, record_child_status_change): New decls.
2950 * process.c (create_process): Avoid disaster if memory is exhausted
2951 while we're processing a vfork, by tightening the critical section
2953 (send_process_frame, process_sent_to, handle_pipe_signal)
2954 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2956 (send_process): No need for setjmp/longjmp any more, since the
2957 SIGPIPE stuff is now gone. Instead, report an error if errno
2959 (record_child_status_change): Now extern. PID and W are now args.
2960 Return void, not bool. All callers changed.
2961 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2962 Remove. All uses removed. This bug should be fixed now in a
2964 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2965 and record the child status change directly. This avoids the
2966 need to futz with the signal mask.
2967 (process_fatal_action): Move here from emacs.c.
2968 (emacs_sigaction_flags): New function, containing
2969 much of what used to be in emacs_sigaction_init.
2970 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2971 caught by emacs, to make races less likely.
2972 (deliver_process_signal): Rename from handle_on_main_thread.
2974 (BACKTRACE_LIMIT_MAX): Now at top level.
2975 (thread_backtrace_buffer, threadback_backtrace_pointers):
2977 (deliver_thread_signal, deliver_fatal_thread_signal):
2978 New functions, for more-accurate delivery of thread-specific signals.
2979 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2980 (deliver_arith_signal): Handle in this thread, not
2981 in the main thread, since it's triggered by this thread.
2982 (maybe_fatal_sig): New function.
2983 (init_signals): New arg DUMPING so that we can be more accurate
2984 about whether we're dumping. Caller changed.
2985 Treat thread-specific signals differently from process-general signals.
2986 Block all signals while handling fatal error; that's safer.
2987 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2989 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2990 Ignore SIGPIPE unless batch.
2991 (emacs_backtrace): Output backtrace for the appropriate thread,
2992 which is not necessarily the main thread.
2993 * syssignal.h: Include <stdbool.h>.
2994 (emacs_raise): New macro.
2995 * xterm.c (x_connection_signal): Remove; no longer needed
2996 now that we use sigaction.
2997 (x_connection_closed): No need to mess with sigmask now.
2998 (x_initialize): No need to reset SIGPIPE handler here, since
2999 init_signals does this for us now.
3001 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3003 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3004 background rect may be larger (Bug#12245).
3006 2012-09-23 Chong Yidong <cyd@gnu.org>
3008 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3010 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3012 * .gdbinit: Just stop at fatal_error_backtrace.
3013 See Stefan Monnier's request in
3014 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3015 Remove no-longer-used query of system type.
3017 2012-09-22 Chong Yidong <cyd@gnu.org>
3019 * search.c (Freplace_match): Doc fix (Bug#12325).
3021 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3023 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3024 (Fline_end_position): Doc fix.
3026 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3028 2012-09-22 Chong Yidong <cyd@gnu.org>
3030 * dispextern.h (struct image_type): Add new slot, storing a type
3031 initialization function.
3033 * image.c (define_image_type): Call the image initializer function
3034 if it is defined. Arguments and return value changed.
3035 (valid_image_p, make_image): Callers changed.
3036 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3037 (gif_type, imagemagick_type, svg_type, gs_type):
3038 Add initialization functions.
3039 (Finit_image_library): Call lookup_image_type.
3040 (CHECK_LIB_AVAILABLE): Macro deleted.
3041 (lookup_image_type): Call define_image_type here, rather than via
3042 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3043 (syms_of_image): Move define_image_type calls for xbm_type and
3044 pbm_type to lookup_image_type.
3046 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3048 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3049 'idle_timers' from here ...
3050 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3051 lists, to avoid infloops when the timer does something stupid,
3052 like reinvoke itself with the same or smaller time-out.
3055 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3057 * window.c (Fsplit_window_internal): Handle only Qt value of
3058 Vwindow_combination_limit separately.
3059 (Qtemp_buffer_resize): New symbol.
3060 (Vwindow_combination_limit): New default value.
3063 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3065 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3066 the new overlay string. (Bug#10159)
3068 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3070 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3071 or that fprintf is async-signal-safe. POSIX doesn't require
3074 2012-09-22 Chong Yidong <cyd@gnu.org>
3076 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3079 2012-09-22 Kenichi Handa <handa@gnu.org>
3081 * composite.c (composition_reseat_it): Handle the case that a
3082 grapheme cluster is not covered by a single font (Bug#12352).
3084 2012-09-21 Chong Yidong <cyd@gnu.org>
3086 * image.c (define_image_type): Avoid adding duplicate types to
3087 image_types (Bug#12463). Suggested by Jörg Walter.
3089 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3091 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3092 (print_load_command_name): Add case LC_DATA_IN_CODE.
3093 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3095 2012-09-21 Glenn Morris <rgm@gnu.org>
3097 * eval.c (Frun_hook_with_args_until_success)
3098 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3100 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3102 * fileio.c (Ffile_selinux_context): Only call freecon when
3103 lgetfilecon succeeded.
3104 (Fset_file_selinux_context): Likewise. (Bug#12444)
3106 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3108 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3109 reordering, locate the cursor by calling set_cursor_from_row; if
3110 that fails, clear the desired glyph matrix before returning a
3111 failure indication to the caller. Fixes leaving garbled display
3112 when fast scrolling with a down-key. (Bug#12403)
3113 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3114 scrolling through multibyte text.
3116 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3118 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3119 calling mark_vectorlike since that's the one that marks the window.
3120 (mark_discard_killed_buffers): Mark the final cdr.
3121 * window.h (struct window): Move prev/next_buffers to the
3122 non-standard fields.
3123 * window.c (make_window): Initialize prev/next_buffers manually.
3125 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3127 Omit unused arg EXPECTED from socket hooks.
3128 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3129 * nsterm.m (ns_term_init):
3130 * termhooks.h (struct terminal.read_socket_hook):
3131 * w32inevt.c (w32_console_read_socket):
3132 * w32term.c (w32_read_socket):
3133 * xterm.c (XTread_socket):
3134 Omit unused arg EXPECTED. All callers changed.
3135 (store_user_signal_events): Return void, not int, since callers no
3136 longer care about the return value. All uses changed.
3138 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3140 * w32gui.h (XParseGeometry): Do not declare.
3142 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3144 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3145 Ignore 'expected'. See Eli Zaretskii in
3146 <http://bugs.gnu.org/12471#8> (last line).
3148 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3149 (XParseGeometry): Now static. Substitute extremal values for
3150 values that are out of range.
3152 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3154 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3156 * nsfns.m (XParseGeometry): Remove.
3157 (Fx_create_frame): Call x_set_offset to correctly interpret
3158 top_pos in geometry.
3160 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3161 (Fx_parse_geometry): If there is a space in string, call
3162 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3164 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3166 * search.c (scan_buffer): Use character positions in calls to
3167 region_cache_forward and region_cache_backward, not byte
3168 positions. (Bug#12196)
3170 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3171 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3173 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3174 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3175 emacs_blocked_malloc, now deleted.
3177 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3179 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3180 The workaround was for improving performance on Solaris 2.4, but
3181 is getting in the way now. Emacs will still work if someone is
3182 still running Solaris 2.4 in a museum somewhere; Sun dropped
3183 support for Solaris 2.4 in 2003.
3184 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3185 * process.c (create_process) [HAVE_WORKING_VFORK]:
3186 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3187 since Emacs no longer uses vfork on that platform.
3189 2012-09-17 Glenn Morris <rgm@gnu.org>
3191 * emacs.c: Use COPYRIGHT.
3193 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3195 Remove configure's --without-sync-input option (Bug#12450).
3196 When auditing signal-handling in preparation for cleaning it up,
3197 I found that SYNC_INPUT has race conditions and would be a real
3198 pain to fix. Since it's an undocumented and deprecated
3199 configure-time option, now seems like a good time to remove it.
3200 Also see <http://bugs.gnu.org/11080#16>.
3201 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3202 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3203 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3204 (malloc_hysteresis):
3205 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3206 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3207 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3208 (dont_register_blocks, bytes_used_when_reconsidered)
3209 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3210 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3211 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3212 Remove. All uses removed.
3213 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3214 implementation, one that depends on whether the new macro
3215 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3217 * atimer.c (run_timers, handle_alarm_signal):
3218 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3219 (handle_async_input, process_pending_signals)
3220 (handle_input_available_signal, init_keyboard):
3221 * nsterm.m (ns_read_socket):
3222 * process.c (wait_reading_process_output):
3223 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3224 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3226 * xterm.c (XTread_socket):
3228 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3229 * eval.c (handling_signal): Remove. All uses removed.
3230 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3231 All uses replaced with the SYNC_INPUT version.
3232 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3234 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3237 * font.c (Ffont_shape_gstring): Remove unused local.
3239 2012-09-16 Glenn Morris <rgm@gnu.org>
3241 * Makefile.in (clean): No longer run nextstep's clean.
3243 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3245 (ns-app): Move here from ns.mk, and simplify.
3246 (clean): Simplify nextstep entry.
3247 * ns.mk: Remove file.
3249 2012-09-17 Kenichi Handa <handa@gnu.org>
3251 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3252 not covert the last few charactes.
3254 2012-09-16 Kenichi Handa <handa@gnu.org>
3256 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3257 here, but just check the validity of glyphs in the glyph-string.
3259 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3261 * window.c (Fwindow_parameter, Fset_window_parameter):
3262 Accept any window as argument (Bug#12452).
3264 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3266 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3267 to ns_term_init to avoid memory leak.
3269 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3270 explicit retain/release.
3271 (ns_term_init): Only allow one display. Initialize outerpool and
3274 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3276 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3277 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3278 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3279 the Microsoft problem in a different way, by altering ../nt/config.nt.
3281 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3296 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3297 by lisp.h. This completes removal of setjmp.h inclusion
3298 erroneously announced in the previous commit. (Bug#12446)
3300 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3303 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3304 not defined as a macro. The latter happens on MS-Windows.
3307 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3309 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3310 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3311 Some instances of '#include <setjmp.h>' removed, if the
3312 only reason for the instance was because "lisp.h" was included.
3313 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3314 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3315 and _longjmp with the new symbols. Emacs already uses _setjmp if
3316 available, so this change affects only POSIXish hosts that have
3317 sigsetjmp but not _setjmp, such as some versions of Solaris and
3318 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3319 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3320 (png_load_body) [HAVE_PNG]:
3321 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3322 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3323 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3324 since PNG requires jmp_buf. This is the only exception to the
3325 general rule that we now use sys_setjmp and sys_longjmp.
3326 This exception is OK since this code does not change the signal
3327 mask or longjmp out of a signal handler.
3329 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3331 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3332 Include "syssignal.h", for 'main_thread'.
3334 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3336 Avoid out-of-range marker position (Bug#12426).
3337 * insdel.c (replace_range, replace_range_2):
3338 Adjust markers before overlays, as suggested by comments.
3339 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3340 Remove redundant check before calling offset_intervals.
3342 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3344 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3345 current buffer (Bug#12387).
3347 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3349 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3351 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3353 Use a more backwards-compatible timer format (Bug#12430).
3354 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3355 vector element, not from the 4th, since PSECS is now at the end.
3356 (Fcurrent_idle_time): Doc fix.
3358 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3360 Function to mark objects and remove killed buffers at once.
3361 * alloc.c (discard_killed_buffers): Rename to ...
3362 (mark_discard_killed buffers) ... new name. Add marking
3363 of remaining objects. Fix comment. Adjust users.
3364 (mark_object): Do not touch frame buffer lists here.
3365 * frame.c (delete_frame): Reset frame buffer lists here.
3367 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3369 Better workaround for GNOME bug when --enable-gcc-warnings.
3370 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3371 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3372 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3374 Simplify SIGIO usage (Bug#12408).
3375 The code that dealt with SIGIO was crufty and confusing, e.g., it
3376 played tricks like "#undef SIGIO" but these tricks were not used
3377 consistently. Simplify mostly by not #undeffing standard symbols,
3378 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3379 or not as we please) rather than "defined SIGIO" (standard symbol
3380 that we probably shouldn't #undef).
3381 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3382 Modules that need it can include it.
3383 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3384 * dispextern.h (ignore_sigio): New decl.
3385 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3386 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3387 * emacs.c (shut_down_emacs):
3388 * keyboard.c (kbd_buffer_store_event_hold):
3389 Use ignore_sigio rather than invoking 'signal' directly.
3390 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3392 (FIONREAD, SIGIO): Do not #undef.
3393 (tty_read_avail_input): Use #error rather than a syntax error.
3394 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3395 for I_PIPE, used by SETUP_SLAVE_PTY.
3396 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3397 * sysdep.c (croak): Remove; no longer needed. This bit of
3398 temporary code, with Fred N. Fish's comment that it's temporary,
3399 has been in Emacs since at least 1992!
3400 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3401 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3402 * syssignal.h (croak): Remove decl.
3403 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3404 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3405 now that we're termios-only.
3406 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3407 * term.c (dissociate_if_controlling_tty): Use #error rather than
3410 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3411 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3412 to work around GNOME bug 683906.
3413 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3414 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3415 This works around GCC bug 54561.
3417 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3419 More fixes for 'volatile' and setjmp/longjmp.
3420 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3421 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3422 (png_load_body) [HAVE_PNG]:
3423 (jpeg_load_body) [HAVE_JPEG]:
3424 New function, with most of the old parent function's body.
3425 (png_load) [HAVE_PNG]:
3426 (jpeg_load) [HAVE_JPEG]:
3427 Invoke the new function, to avoid longjmp munging our locals.
3428 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3429 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3430 longjmp is passed 2, as the C standard doesn't guarantee this.
3431 Instead, store the failure code into mgr->failure_code.
3433 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3435 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3436 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3437 (syms_of_keyboard): Remove support for unread-command-char.
3439 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3441 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3442 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3443 violation. (Bug#12426)
3445 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3447 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3449 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3451 * eval.c: Add `inhibit-debugger'.
3452 (Qinhibit_debugger): New symbol.
3453 (call_debugger): Bind it instead of Qdebug_on_error.
3454 (maybe_call_debugger): Test Vinhibit_debugger.
3455 (syms_of_eval): Define inhibit-debugger.
3456 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3457 (syms_of_xdisp): Remove inhibit-debug-on-message.
3459 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3461 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3462 If a nonvolatile local variable is written before a _longjmp to
3463 the frame containing the variable, and is read after the _longjmp,
3464 the value read is indeterminate. Some local variables of type
3465 'struct handler' and 'struct catchtag' are used in this way, so
3466 mark each of their slots as volatile if the slot can be set before
3467 _longjmp and read afterwards.
3468 * lisp.h (struct handler): var and chosen_clause are now volatile.
3469 (struct catchtag): val, next, and pdlcount are now volatile.
3471 * bidi.c (bidi_push_it, bidi_pop_it):
3472 * fns.c (copy_hash_table):
3473 * image.c (define_image_type):
3474 * keyboard.c (kbd_buffer_store_event_hold):
3475 * process.c (Fprocess_send_eof):
3476 * xfaces.c (x_create_gc) [HAVE_NS]:
3477 * xgselect.c (xg_select):
3478 Prefer assignment to memcpy when either will do.
3480 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3481 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3482 time an item is removed. No need to mark this function 'inline';
3483 the compiler knows better than we do.
3485 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3487 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3488 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3489 to change_frame_size (Bug#12388).
3490 (windowDidResize:): Pass YES to updateFrameSize.
3492 * nsterm.h: Add delay parameter to updateFrameSize.
3494 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3496 Discard killed buffers from deleted window and frame objects.
3497 This reduces an amount of references to killed buffers and
3498 helps GC to reclaim them faster.
3499 * alloc.c (discard_killed_buffers): New function.
3500 (mark_object): Use it for deleted windows and frames.
3501 (mark_object): If symbol's value is set up for a killed buffer
3502 or deleted frame, restore its global binding.
3503 * data.c (swap_in_global_binding): Add GC notice.
3504 (swap_in_symval_forwarding): Use convenient set_blv_where.
3505 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3506 * window.h: ... to here.
3508 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3510 Convenient macro to check whether the buffer is live.
3511 * buffer.h (BUFFER_LIVE_P): New macro.
3512 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3513 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3515 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3517 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3518 composition cases (Bug#12364).
3520 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3521 overhang of succeeding glyphs overlapping box cursor.
3523 * w32term.c (x_draw_glyph_string): Likewise.
3525 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3527 Simplify, document, and port floating-point (Bug#12381).
3528 The porting part of this patch fixes bugs on non-IEEE platforms
3529 with frexp, ldexp, logb.
3530 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3532 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3533 support, by removing commented-out code and briefly listing the
3534 C89 functions excluded. The commented-out stuff was confusing
3535 maintenance, e.g., we thought we needed cbrt but it was commented out.
3536 (logb): Remove decl; no longer needed.
3537 (isfinite): New macro, if not already supplied.
3538 (isnan): Don't replace any existing macro.
3539 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3540 are present on all C89 platforms.
3541 (Ffrexp): Do not special-case zero, as frexp does the right thing
3543 (Flogb): Do not use logb, as it doesn't have the desired meaning
3544 on hosts that use non-base-2 floating point. Instead, stick with
3545 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3546 frexp, to avoid getting an unspecified result.
3548 * xdisp.c (Qinhibit_debug_on_message): Now static.
3550 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3552 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3553 NSBezierPath (Bug#12131).
3555 2012-09-10 Chong Yidong <cyd@gnu.org>
3557 * fns.c (Fdelq, Fdelete): Doc fix.
3559 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3561 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3562 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3564 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3566 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3567 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3570 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3572 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3573 left fringe if the window has a left margin. This avoids leaving
3574 traces of the cursor because its leftmost pixel is not drawn over.
3576 * dispnew.c (update_window_line): When the left margin area of a
3577 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3578 that screen line. (Bug#12277)
3580 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3582 Assume C89 or later for math functions (Bug#12381).
3583 This simplifies the code, and makes it a bit smaller and faster,
3584 and (most important) makes it easier to clean up signal handling
3585 since we can stop worring about floating-point exceptions in
3586 library code. That was a problem before C89, but the problem
3587 went away many years ago on all practical Emacs targets.
3588 * data.c, image.c, lread.c, print.c:
3589 Don't include <math.h>; no longer needed.
3590 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3591 might be autoconfigured, as that never happens.
3593 * doprnt.c (DBL_MAX_10_EXP):
3594 * print.c (DBL_DIG):
3595 Remove. C89 or later always defines these.
3596 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3597 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3598 (arith_error, domain_error, domain_error2):
3599 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3600 no longer needed -- we simply return what C returns. All uses removed.
3601 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3603 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3604 Remove. All uses expanded, as these macros are no longer used
3605 more than once and are now more trouble than they're worth.
3606 (Ftan): Use tan, not sin / cos.
3607 (Flogb): Assume C89 frexp.
3608 (fmod_float): Assume C89 fmod.
3609 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3610 (init_floatfns): Remove. All uses removed.
3612 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3614 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3615 compositeToPoint for OSX < 10.6 (Bug#12390).
3617 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3619 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3620 This produces more-accurate results.
3622 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3624 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3625 changes (Bug#12088).
3627 2012-09-08 Chong Yidong <cyd@gnu.org>
3629 * syntax.c (Fstring_to_syntax): Doc fix.
3631 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3633 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3634 in the internal border.
3635 (x_set_window_size): Remove static variables and their usage.
3636 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3637 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3638 Remove fringe/internal border adjustment (Bug#11052).
3639 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3640 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3641 (ns_fix_rect_ibw): Remove.
3642 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3643 (ns_dumpglyphs_box_or_relief): Ditto.
3644 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3646 (ns_dumpglyphs_image): Ditto.
3647 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3649 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3650 their usage. Add fringe_extended_p and its use as in other terms.
3651 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3652 scroll bar was removed.
3653 (updateFrameSize): New function.
3654 (windowDidResize): Move code to updateFrameSize and call it.
3656 * nsterm.h (EmacsView): Add updateFrameSize.
3658 2012-09-07 Chong Yidong <cyd@gnu.org>
3660 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3662 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3664 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3666 More signal-handler cleanup (Bug#12327).
3667 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3668 Problem introduced when merging patches. Noted by Eli Zaretskii in
3669 <http://bugs.gnu.org/12327#67>.
3670 * floatfns.c: Comment fix.
3671 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3672 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3673 and anyway the declaration is harmless even if SIGDANGER is not defined.
3674 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3675 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3676 source files not surprisingly expected syssignal.h to define, or
3677 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3678 Include <sys/ioctl.h>, for FIONREAD.
3679 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3680 This eliminates a problem whereby other files mysteriously had
3681 to include "syssignal.h" before including "systty.h" if they
3682 wanted to use "#ifdef SIGIO".
3684 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3686 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3688 * w32.c (sigemptyset): Empty the set.
3689 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3691 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3693 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3695 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3696 (mark_object): Likewise for frame objects.
3698 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3700 * syssignal.h (handle_on_main_thread): Always declare,
3701 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3702 This ports to platforms without HAVE_PTHREAD.
3704 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3706 Signal-handler cleanup (Bug#12327).
3707 Emacs's signal handlers were written in the old 4.2BSD style with
3708 sigblock and sigmask and so forth, and this led to some
3709 inefficiencies and confusion. Rewrite these to use
3710 pthread_sigmask etc. without copying signal sets around. Also,
3711 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3712 'signal', and instead use functions that do not attempt to take
3713 over the system name space. This patch causes Emacs's text
3714 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3715 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3716 Do not include <signal.h> or "syssignal.h", as these
3717 modules do not use signals.
3718 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3719 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3720 Do not include <signal.h>, as "syssignal.h" does that for us now.
3721 * atimer.c (sigmask_atimers): New function.
3722 (block_atimers, unblock_atimers): New functions,
3723 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3725 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3726 no longer needed here.
3727 * emacs.c (main): Inspect existing signal handler with sigaction,
3728 so that there's no need to block and unblock SIGHUP.
3729 * sysdep.c (struct save_signal): New member 'action', replacing
3730 old member 'handler'.
3731 (save_signal_handlers, restore_signal_handlers):
3732 Use sigaction instead of 'signal' to save and restore.
3733 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3734 New function. All users of 'signal' modified to use set_sighandler
3735 if they're writeonly, and to use sys_signal if they're read+write.
3736 (emacs_sigaction_init, forwarded_signal): New functions.
3737 (sys_signal): Remove. All uses replaced by calls to sigaction
3738 and emacs_sigaction_init, or by direct calls to 'signal'.
3739 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3740 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3741 all uses replaced by pthread_sigmask etc. calls.
3742 * syssignal.h: Include <signal.h>.
3743 (emacs_sigaction_init, forwarded_signal): New decls.
3744 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3745 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3746 (sigmask, sys_sigmask): Remove; no longer needed.
3747 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3748 (sigblock, sigunblock, sigfree):
3749 (sigsetmask) [!defined sigsetmask]:
3750 Remove. All uses replaced by pthread_sigmask.
3751 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3752 no longer need to be replaced, and its typical old uses
3753 are now done via emacs_sigaction_init and sigaction.
3754 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3755 (sys_sigdel): Remove; unused.
3756 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3758 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3760 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3761 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3763 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3765 Explicitly mark buffer_defaults and buffer_local_symbols.
3766 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3767 mark_local_symbols here.
3768 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3769 since special buffers aren't marked here any more.
3770 (allocate_buffer): Chain new buffer with all_buffers here...
3771 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3773 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3774 (syms_of_buffer): Remove staticpro of the above.
3775 (init_buffer_once): Set names for buffer_defaults and
3776 buffer_local_symbols.
3778 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3780 Use bool for booleans in font-related modules.
3781 * font.c (font_intern_prop, font_style_to_value)
3782 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3783 (generate_otf_features, font_check_otf_features, font_check_otf)
3784 (font_match_p, font_list_entities, font_at):
3785 * fontset.c (fontset_id_valid_p, reorder_font_vector
3786 (fontset_find_font, Fset_fontset_font)
3787 (face_suitable_for_char_p) [0]:
3788 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3789 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3790 (m17n_flt_initialized, ftfont_shape_by_flt):
3791 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3792 * nsfont.m (nsfont_draw):
3793 * w32font.c (w32font_draw):
3794 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3795 Use bool for booleans.
3796 * font.h: Adjust to above API changes.
3797 (struct font, struct font_driver, struct font_driver_list):
3798 Use bool for booleans.
3799 (struct font): Remove useless member encoding_type.
3801 * fontset.c, xftfont.c: Omit unnecessary static decls.
3803 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3805 * alloc.c (mark_object): Revert window marking code
3806 since it's unsafe for the Fset_window_configuration.
3808 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3810 Fix race conditions with signal handlers and errno (Bug#12327).
3811 Be more systematic about preserving errno whenever a signal
3812 handler returns, even if it's not in the main thread. Do this by
3813 renaming signal handlers to distinguish between signal delivery
3814 and signal handling. All uses changed.
3815 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3816 * data.c (deliver_arith_signal): Rename from arith_error.
3817 * dispnew.c (deliver_window_change_signal): Rename from
3818 window_change_signal.
3819 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3820 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3821 * keyboard.c (deliver_input_available_signal): Rename from
3822 input_available_signal.
3823 (deliver_user_signal): Rename from handle_user_signal.
3824 (deliver_interrupt_signal): Rename from interrupt_signal.
3825 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3826 (deliver_child_signal): Rename from sigchld_handler.
3827 * atimer.c (handle_alarm_signal):
3828 * data.c (handle_arith_signal):
3829 * dispnew.c (handle_window_change_signal):
3830 * emacs.c (handle_fatal_signal, handle_danger_signal):
3831 * keyboard.c (handle_input_available_signal):
3832 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3833 * process.c (handle_pipe_signal, handle_child_signal):
3834 New functions, with the actual signal-handling code taken from the
3835 original respective signal handlers, sans the sporadic attempts to
3836 preserve errno, since that's now done by handle_on_main_thread.
3837 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3838 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3839 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3841 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3842 Move initialization of main_thread to sysdep.c's init_signals.
3843 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3844 our usage, and simplifies the mainline code.
3845 (record_child_status_change): New static function, as a helper
3846 for handle_child_signal, and with most of the old child handler's
3848 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3849 (handle_child_signal): Use the above.
3850 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3851 Moved here from emacs.c.
3852 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3853 code moved here from emacs.c's main function.
3854 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3855 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3856 This lets callers save and restore errno properly.
3858 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3860 Remove redundant or unused things here and there.
3861 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3862 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3863 * editfns.c (Fcompare_buffer_substrings): Likewise.
3864 * frame.h (struct terminal, struct font_driver_list):
3865 Remove redundant declarations.
3866 * window.h (Qleft, Qright): Likewise.
3868 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3870 Do not mark objects from deleted buffers, windows and frames.
3871 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3872 (mark_object): Likewise for windows and frames.
3874 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3876 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3877 buffer_defaults and buffer_local_symbols as valid objects.
3878 Return special value to denote them.
3880 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3882 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3883 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3884 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3885 (file_name_absolute_p, Fsubstitute_in_file_name):
3886 (check_executable, check_writable, Ffile_accessible_directory_p)
3887 (Fset_file_selinux_context, Fdefault_file_modes)
3888 (Finsert_file_contents, choose_write_coding_system)
3889 (Fwrite_region, build_annotations, a_write, e_write)
3891 * filelock.c (boot_time_initialized, get_boot_time)
3892 (get_boot_time_1, lock_file_1, within_one_second):
3893 * floatfns.c (in_float):
3894 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3895 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3896 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3897 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3898 * window.c (compare_window_configurations):
3899 Use bool for booleans.
3900 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3901 (Fdefault_file_modes): Now mode_t, not int, for modes.
3902 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3903 (internal_delete_file): Now returns void, not a (boolean) int,
3904 since nobody was looking at the return value.
3905 * lisp.h, window.h: Adjust to above API changes.
3907 * xdisp.c (set_message): Simplify and reindent last change.
3909 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3911 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3913 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3915 * eval.c (call_debugger): Make the function non-static so that we
3916 can call it from set_message.
3918 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3919 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3921 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3923 Give more-useful info on a fatal error (Bug#12328).
3924 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3925 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3926 of doing the work ourselves.
3927 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3928 do most of the work.
3929 (fatal_error_backtrace): New function, taken from the guts
3930 of the old fatal_error_signal, but with a new option to output
3932 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3933 info about the signal than just its number.
3934 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3935 * sysdep.c: Include <execinfo.h>
3936 (emacs_backtrace): New function, taken partly from the previous
3937 code of the 'die' function.
3938 (emacs_abort): Call fatal_error_backtrace rather than abort.
3940 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3942 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3943 eager (load-time) macro-expansion.
3944 * lisp.mk (lisp): Add macroexp.
3946 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3948 Simplify redefinition of 'abort' (Bug#12316).
3949 Do not try to redefine the 'abort' function. Instead, redo
3950 the code so that it calls 'emacs_abort' rather than 'abort'.
3951 This removes the need for the NO_ABORT configure-time macro
3952 and makes it easier to change the abort code to do a backtrace.
3953 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3954 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3955 Remove; sysdep.c's emacs_abort now takes its place.
3956 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3957 'abort' changed to use 'emacs_abort'.
3958 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3959 (abort) [!defined abort]: Rename to ...
3960 (emacs_abort): ... new name.
3961 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3962 the place of the old 'abort' in emacs.c.
3963 * w32.c, w32fns.c (abort): Do not #undef.
3964 * w32.c (emacs_abort): Rename from w32_abort.
3966 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3968 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3969 offsets[j].dv, since the y axis of the screen coordinates points
3970 down, while the y axis of the font definition coordinates points
3971 up. This fixes display of Arabic diacritics such as KASRA and
3972 KASRATAN. (Bug#11860)
3974 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3976 Be more systematic about _setjmp vs setjmp.
3977 * alloc.c (test_setjmp, mark_stack):
3978 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3979 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3980 (png_load, my_error_exit, jpeg_load):
3981 * process.c (send_process_trap, send_process):
3982 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3983 The underscored versions are up to 30x faster on some hosts.
3984 Formerly, the code used setjmp+longjmp sometimes and
3985 _setjmp+_longjmp at other times, with no particular reason to
3986 prefer setjmp+longjmp.
3988 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3990 Fix minor problem found by static checking.
3991 * buffer.c (Fdelete_all_overlays): Return nil.
3993 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3995 * buffer.c (Fdelete_all_overlays): New function.
3997 2012-09-03 Chong Yidong <cyd@gnu.org>
3999 * gtkutil.c: Add extern decl for Qxft.
4001 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4003 * emacs.c, eval.c: Use bool for boolean.
4004 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4005 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4006 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4007 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4008 (main, decode_env_path, Fdaemon_initialized):
4009 * eval.c (call_debugger, Finteractive_p, interactive_p):
4010 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4011 (maybe_call_debugger, Fbacktrace):
4012 * process.c (read_process_output, exec_sentinel):
4013 Use bool for booleans.
4014 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4015 All callers changed.
4016 * eval.c (interactive_p): Omit always-true boolean argument
4017 EXCLUDE_SUBRS_P. All callers changed.
4018 * dispextern.h, lisp.h: Reflect above API changes.
4019 * firstfile.c (dummy): Use the address of 'main', whose signature
4020 won't change, instead of the address of 'initialize', whose
4021 signature just changed from int to bool.
4022 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4023 * msdos.c (fatal_error_in_progress): ... from here.
4024 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4026 (redisplay_internal, unwind_redisplay): Simply clear
4027 REDISPLAYING_P when unwinding, instead of saving its previous,
4028 always-false value and then restoring it.
4030 Clean up some extern decls.
4031 Mostly, this hoists extern decls out of .c files and into .h files.
4032 That way, we're more likely to catch errors if the interfaces change.
4033 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4034 declare xg_mark_data.
4035 * dispextern.h (x_frame_parm_handlers):
4037 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4038 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4039 (Qultra_bold, Qoblique, Qitalic):
4040 Move extern decl here from .c file.
4041 * alloc.c (xg_mark_data) [USE_GTK]:
4043 * eval.c (Qlexical_binding):
4044 * fns.c (time) [!HAVE_UNISTD_H]:
4045 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
4046 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

4048 * lread.c (Qinternal_interpreter_environment):
4049 * minibuf.c (Qbuffer):
4050 * process.c (QCfamily, QCfilter):
4051 * widget.c (free_frame_faces):
4052 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4053 * xfont.c (x_clear_errors):
4054 * xterm.c (x_frame_parm_handlers):
4055 Remove now-redundant extern decls.
4056 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4057 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4059 * xfaces.c: Remove unnecessary static decls.
4060 * xterm.c (updating_frame): Remove decl of nonexistent object.
4062 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4063 when building globals.h, as the objects that are not built on
4064 this host are not needed to compile C files on this host.
4066 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4068 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4070 * frame.h: Add missing prototype for x_wm_set_size_hint.
4072 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4074 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.

4076 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4077 (Fsubstitute_command_keys):

4082 (make_buffer_string, make_buffer_string_both)
4083 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
4084 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

4120 offset adjustment values separately for each cluster. (Bug#11860)
4122 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4123 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4124 about implicit conversions from integer to pointer.

4182 window system declarations.
4184 * frame.h: Move common functions here: set_frame_menubar,
4185 x_set_window_size, x_sync, x_get_focus_frame,
4186 x_set_mouse_position, x_set_mouse_pixel_position,
4187 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4217 the frames which are reachable from Vframe_list.
4218 * term.c (mark_ttys): Remove.
4219 (init_tty): Safely initialize 'top_frame' slot with Qnil.

4243 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4244 for GCC 4.7.1 x86-64.
4246 2012-08-30 Glenn Morris <rgm@gnu.org>
4248 * lread.c (init_lread): For out-of-tree builds, only add the
4249 source directory's site-lisp dir to the load-path if it exists,
4250 consistent with in-tree builds. (Bug#12302)
4252 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

4273 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4274 Add window_closed and button_values. Add void as return value for
4275 add(Button|String|Split). addButton takes int instead of Lisp_Object.

4486 It was meant to be temporary and it often doesn't work,
4487 because when IDX has side effects the behavior of IDX==IDX
4488 is undefined. See Stefan Monnier in

4535 Use bool for booleans, instead of int.
4536 * lisp.h, process.h: Adjust prototypes to match above changes.
4537 * callint.c (Fcall_interactively): Don't assume the mark's
4538 offset fits in 'int'.
4540 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4542 * buffer.c, buffer.h: Use bool for boolean.
4543 * buffer.c (reset_buffer_local_variables)
4544 (buffer_lisp_local_variables, Fset_buffer_modified_p)
4545 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
4546 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
4547 (overlay_touches_p, overlay_strings, Foverlay_put)
4548 (report_overlay_modification, call_overlay_mod_hooks):
4549 (mmap_enlarge, mmap_set_vars):
4550 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4551 Use bool for booleans, instead of int.
4552 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4553 since the 1-or-0 return value is always ignored anyway.
4554 (mmap_initialized_p):
4555 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4556 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4558 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4560 * bidi.c: Use bool for boolean.
4561 This is a bit more readable, and makes the text segment of bidi.o
4562 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4563 Presumably it's faster too.
4564 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
4566 (bidi_cache_find_level_change, bidi_cache_iterator_state)
4567 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
4568 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
4569 (bidi_explicit_dir_char, bidi_level_of_next_char)
4570 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4571 Use bool for booleans, instead of int.
4572 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4573 (bidi_unshelve_cache): Adjust decls to match code.
4575 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4577 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4580 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4582 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4583 * atimer.h: Include <stdbool.h>.
4585 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4587 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4588 compile time tests instead of run time tests on systems that do
4590 (FRAME_MAC_P): Remove leftover from deleted code.
4591 * frame.c (syms_of_frame): Remove leftover from deleted code.
4593 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4595 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4597 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4599 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4600 Otherwise, the compiler complains about (A?B:C) where B is void
4601 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4602 (fontset_add): Return void, for FONTSET_ADD.
4604 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4606 * alloc.c: Use bool for booleans.
4607 (gc_in_progress, abort_on_gc)
4608 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4609 (dont_register_blocks) [GC_MALLOC_CHECK]:
4610 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4611 (check_string_bytes, make_specified_string, memory_full)
4612 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4613 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4614 (mark_stack, valid_pointer_p, make_pure_string)
4615 (Fgarbage_collect, survives_gc_p, gc_sweep):
4616 Use bool for booleans, instead of int.
4617 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4618 Remove unused local.
4619 * alloc.c (PURE_POINTER_P):
4620 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4621 * editfns.c (Fformat):
4622 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4624 * fns.c (sweep_weak_table):
4625 * lisp.h (suppress_checking, push_message, survives_gc_p)
4626 (make_pure_string, gc_in_progress, abort_on_gc):
4627 * lread.c (readchar, read1):
4628 * print.c (Fprin1_to_string):
4629 * xdisp.c (push_message):
4630 Use bool for booleans affected directly or indirectly by
4633 Make recently-introduced setters macros.
4634 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4635 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4636 (set_fontset_default, set_fontset_fallback): Rename from their
4637 upper-case counterparts, and make them functions rather than macros.
4638 This is more consistent with the other recently-introduced setters.
4639 These don't need to be inline, since they're local.
4641 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4643 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4644 the loop (Bug#12247).
4646 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4648 * lisp.h (vcopy): Use memcpy rather than our own loop.
4649 This fixes a performance regression introduced by the recent
4650 addition of vcopy. This means 'vcopy' will need to be modified
4651 for a copying collector, but that's OK. Also, tighten the
4652 checking in the assertion.
4654 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4656 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4657 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4658 non-base glyph for the width of the base character, according to
4659 what x_draw_composite_glyph_string_foreground expects.
4660 Generate WADJUST value according to composition_gstring_width's
4661 expectations, to produce correct width of the composed character.
4662 Reverse the sign of the DU offset produced by ScriptPlace.
4664 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4666 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4668 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4670 Avoid direct writes to contents member of struct Lisp_Vector.
4671 * lisp.h (vcopy): New function to copy data into vector.
4672 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4673 * fns.c (Ffillarray): Use ASET.
4674 * keyboard.c (timer_check_2): Use AREF and ASET.
4675 (append_tool_bar_item, Frecent_keys): Use vcopy.
4676 * lread.c (read_vector): Use ASET.
4677 * msdos.c (Frecent_doskeys): Use vcopy.
4678 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4679 (Finternal_merge_in_global_face): Use ASET and vcopy.
4680 * xfont.c (xfont_list_pattern): Likewise.
4682 2012-08-21 Martin Rudalics <rudalics@gmx.at>
4684 * window.c (Fwindow_point): For the selected window always return
4685 the position of its buffer's point.
4686 (Fset_window_point): For the selected window always go in its
4687 buffer to the specified position.
4689 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4691 Setter macros for fontsets.
4692 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4693 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4694 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4697 2012-08-20 Glenn Morris <rgm@gnu.org>
4699 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4700 Don't assume that `ln -f' works.
4702 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4704 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4705 and later about non-assignments with no effect. See discussion at
4706 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4709 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4711 Inline setter functions for Lisp_Objects slots of struct specbinding.
4712 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
4715 2012-08-20 Martin Rudalics <rudalics@gmx.at>
4717 * window.c (select_window): Always make selected window's buffer
4720 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4722 Use AREF and ASET for docstrings of category tables.
4723 * category.h (CATEGORY_DOCSTRING): Use AREF.
4724 (SET_CATEGORY_DOCSTRING): Use ASET.
4725 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
4727 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4729 Inline setter functions for hash table members.
4730 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4731 (set_hash_hash, set_hash_index): Rename with _slot suffix.
4732 (set_hash_key_and_value, set_hash_index, set_hash_next)
4733 (set_hash_hash): New functions.
4734 * charset.c, fns.c: Adjust users.
4736 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4738 Inline getter and setter functions for per-buffer values.
4739 * buffer.h (per_buffer_default, set_per_buffer_default)
4740 (per_buffer_value, set_per_buffer_value): New functions.
4741 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
4742 * buffer.c, data.c: Adjust users.
4744 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
4746 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
4748 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4750 Rely on <config.h> + <unistd.h> to declare 'environ',
4751 as gnulib does this if the system doesn't.
4752 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4753 Remove declaration. MS-Windows declares it on stdlib.h which is
4754 included by conf_post.h.
4755 * emacs.c (environ) [DOUG_LEA_MALLOC]:
4756 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
4757 * vm-limit.c: Include <unistd.h>, for 'environ'.
4759 * unexaix.c, unexcoff.c: Include "mem-limits.h".
4760 (start_of_data): Remove decl; mem-limits.h provides it.
4762 * xdisp.c (handle_invisible_prop): Make it a bit faster
4763 and avoid a gcc -Wmaybe-uninitialized diagnostic.
4765 2012-08-19 Chong Yidong <cyd@gnu.org>
4767 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
4770 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
4772 * .gdbinit: Use call instead of set when calling a function in the
4775 * data.c (set_internal): Don't use set_blv_found.
4776 (Fkill_local_variable): Likewise.
4778 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4780 * nsfont.m (ns_ascii_average_width): Ensure the string
4781 ascii_printable is initialized with a null-terminated character
4782 array. Otherwise, it can contain undesired extra characters.
4784 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4786 port new setting code to Sun C 5.8 2005/10/13
4787 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4788 Return void, not Lisp_Object. Otherwise, the compiler
4789 complains about (A?B:C) where B is void and C is Lisp_Object
4790 when compiling CHAR_TABLE_SET, due to the recent change to
4791 the API of sub_char_table_set_contents.
4793 2012-08-18 Chong Yidong <cyd@gnu.org>
4795 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
4796 for the string case (Bug#3874).
4798 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4800 * buffer.h (BSET): Remove (Bug#12215).

4879 are compiled into code.
4880 (tset_param_alist): New setter function.
4882 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

4917 A few more naming-convention fixes for getters and setters.
4918 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,

4920 (set_buffer_overlays_after): Move here from buffer.h, and rename
4921 from buffer_overlays_set_after.
4922 * buffer.h (buffer_intervals): Rename from buffer_get_intervals.

4949 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
4950 "set_char_table_parent (char_table, parent);".
4951 The old version was confusing because it used the same name
4952 'parent' for two different things.
4954 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
4956 Functions to get and set Lisp_Object fields of buffer-local variables.

5623 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5624 * w32.c (init_environment): Change the default values of many
5625 environment variables in dflt_envvars[] to NULL, to avoid pushing
5626 them into environment when they were not already defined.
5627 Remove the code that deletes site-lisp subdirectories from the default
5628 value of EMACSLOADPATH, as it is no longer needed.
5629 (check_windows_init_file): Now external, not static.
5630 Use Vload_path as is, without adding anything, as this function is now
5631 called when Vload_path is already set up.
5633 * w32.h (check_windows_init_file): Add prototype.
5635 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

5642 installation tree, as appropriate.
5644 * callproc.c (init_callproc_1): Call decode_env_path instead of
5645 doing its equivalent by hand.

5647 the code that sets Vexec_path run on MS-Windows.
5649 * lread.c (init_lread): Add comments to #ifdef's.
5651 * msdos.c (dos_set_window_size, IT_update_begin)

5663 Remove unnecessary casts involving pointers.
5664 These casts are no longer needed now that we assume C89 or later,

5678 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5679 Remove unnecessary pointer casts.
5680 * alloc.c (record_xmalloc): New function.
5681 * lisp.h (record_xmalloc): New decl.
5682 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5683 more like a function. This is because the pointer cast is not
5684 needed. All uses changed.
5685 * print.c (print_string, print_error_message): Avoid length recalc.
5687 Improve fix for macroexp crash with debugging (Bug#12118).
5688 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5689 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5690 not supposed to be invoked from the garbage collector.
5691 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
5692 (gc_aset): New function, which is like ASET but can be
5693 used in the garbage collector.

5709 headers (most versions of MinGW w32api don't).
5710 (get_security_info, create_symbolic_link)
5711 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

5722 with addition of handling of symlinks and support for 'lstat'.
5723 If possible, get file's attributes and security information by
5724 handle, not by name. Produce S_IFLNK bit for symlinks, when
5725 called from 'lstat'.
5726 (stat, lstat): New functions, call 'stat_worker'.
5727 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5728 symlinks when the underlying filesystem supports them.
5730 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5732 Fix macroexp crash on Windows with debugging (Bug#12118).
5733 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5734 checking subscripts; problem introduced with the recent
5735 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5736 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5737 since it's used in non-static inline functions now.
5739 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5740 Don't assume buffer size fits in 'int'. Remove unused local.

5760 * composite.c (COMPOSITE_INLINE):
5761 * dispnew.c (DISPEXTERN_INLINE):
5762 * sysdep.c (SYSTIME_INLINE):
5763 Define to EXTERN_INLINE, so that the corresponding functions
5764 are compiled into code.
5765 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5766 (INLINE_HEADER_END): New macros.
5767 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5787 hard-coding the path separator.
5789 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5791 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5792 This how ASET and AREF are supposed to work, and makes
5793 it easier to think about future improvements. See
5794 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5795 * charset.h (set_charset_attr): New function.

6287 the fix for 12036 would have avoided some of the problems noted in

6298 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6299 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6300 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6301 not be usable in #if. This simplifies things.
6303 2012-07-26 Juanma Barranquero <lekktu@gmail.com>

6310 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6311 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6312 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6313 Adjust to changes in lisp.h and emacs.c, by using
6314 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6315 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6316 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6317 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6318 instead of gdb_valbits.
6319 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6320 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6321 instead of gdb_array_mark_flag.
6322 (xboolvector): Get size from $->size, not $->header.size.
6323 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6324 (xreload, hook-run, hookpost-run): Remove.
6325 * emacs.c: Include <verify.h>.
6326 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

6330 (gdb_USE_LSB_TAG): New enum constants.
6331 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6332 Also define these as enum constants, so they're visible to GDB.
6333 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6334 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6335 as constants, so they're visible to GDB.

6337 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6338 Now enum constants, not macros, so they're visible to GDB.
6339 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6340 more convenient now. All uses changed.
6341 (VALMASK) [USE_LSB_TAG]: Also define in this case.

6354 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6356 Use typedef for EMACS_INT, EMACS_UINT.
6357 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6358 than macros. This simplifies debugging in the usual case, since
6359 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6360 and it allows expressions involving EMACS_INT casts.
6361 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6363 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6379 (init_buffer_once): Initialize indirection counters of
6380 buffer_defaults and buffer_local_symbols (for sanity and safety).
6382 2012-07-24 Eli Zaretskii <eliz@gnu.org>

6413 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6415 Swap buffer text indirection counters in Fbuffer_swap_text.
6416 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6417 This avoids crash reported by Christoph Scholtes at
6418 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6420 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6422 * nsmenu.m (Popdown_data): New struct.

6445 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6447 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6448 as it's limited by the amount of memory, not by INT_MAX.
6450 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6452 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

6609 * keyboard.c (command_loop_1): Set it.
6610 * cmds.c (Fself_insert_command): Use it to only remove boundaries that

7195 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
7196 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
7197 not functions. All uses rewritten to use the following, respectively:
7198 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
7199 (add_emacs_time, sub_emacs_time): New functions.
7200 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

7226 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7227 * nsterm.m (ns_term_init):
7228 Avoid the need for strncpy, by using build_string or
7229 make_unibyte_string directly. Use dtoastr, not snprintf.
7230 * process.c (Fmake_network_process): Diagnose service names that
7231 are too long, rather than silently truncating them or creating
7232 non-null-terminated names.
7233 (Fnetwork_interface_info): Likewise, for interface names.
7234 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7235 Prefer sprintf to strncat.
7236 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

7242 Clarify fallback case.
7244 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7246 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
7247 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
7248 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7249 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7250 where argument type is known to be a Lisp_Cons.

7262 Optimize pure C strings initialization.
7263 * lisp.h (make_pure_string): Fix prototype.
7264 (build_pure_c_string): New function, defined as static inline. This
7265 provides a better opportunity to optimize away calls to strlen when
7266 the function is called with compile-time constant argument.
7267 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7268 argument, adjust users accordingly. Use build_pure_c_string where
7270 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7271 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7272 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7274 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7276 Avoid calls to strlen in miscellaneous functions.
7277 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7278 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7279 * lread.c (openp): Likewise.
7281 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7283 Avoid calls to strlen in path processing functions.
7284 * fileio.c (file_name_as_directory): Add comment. Change to add
7285 srclen argument and return the length of result. Adjust users

7289 Adjust users accordingly.
7290 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7292 2012-07-10 Glenn Morris <rgm@gnu.org>
7294 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
7295 Move PENDING_OUTPUT_COUNT definition to configure.

7299 * s/gnu.h (DATA_START): Move definitions to configure.
7301 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7302 We include usg5-4-common.h, which defines them both.
7304 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7305 O_RDONLY already includes it).
7307 Stop ns builds setting the EMACSLOADPATH environment variable.
7308 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7309 Now it does not set EMACSLOADPATH, just returns the load-path string.
7310 * nsterm.h: Update accordingly.
7311 * lread.c [HAVE_NS]: Include nsterm.h.
7312 (init_lread) [HAVE_NS]: Use ns_load_path.

7315 2012-07-09 Glenn Morris <rgm@gnu.org>
7317 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7318 since the included bsd-common.h does so.
7320 Stop ns builds setting the EMACSPATH environment variable.
7321 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7322 (ns_init_paths): Do not set EMACSPATH.
7323 * nsterm.h (ns_exec_path): Add it.
7324 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7327 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7329 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7331 * process.c (wait_reading_process_output): 'waitchannels' was unset
7332 when read_kbd || !NILP (wait_for_cell); fix this.
7334 Add GCC-style 'const' attribute to functions that can use it.
7335 * character.h (char_resolve_modifier_mask):
7336 * keyboard.h (make_ctrl_char):
7337 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7345 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7346 Add decls with ATTRIBUTE_CONST.
7348 Minor improvements to make_formatted_string.
7349 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7350 where int is good enough, as vsprintf returns an int.
7351 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7353 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7355 Use make_formatted_string to avoid double length calculation.
7356 * lisp.h (make_formatted_string): New prototype.
7357 * alloc.c (make_formatted_string): New function.
7358 * buffer.c (Fgenerate_new_buffer_name): Use it.

7380 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7382 Move marker debugging code under MARKER_DEBUG.
7383 * marker.c (MARKER_DEBUG): Move marker debugging code under
7384 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7385 for bootstrap with --enable-checking (~3x slowdown reported
7386 by Juanma Barranquero <lekktu@gmail.com>).
7387 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7389 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7391 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7392 See <http://bugs.gnu.org/11825#29>.
7394 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7396 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7397 has no font, use the frame's font. (Bug#11813)
7398 (display_line): Add commentary about displaying truncation glyphs
7400 (produce_special_glyphs): Move here from term.c.
7402 * term.c (produce_special_glyphs): Move to xdisp.c.
7404 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7407 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7409 * xdisp.c (display_line): Avoid warning about implicit declaration
7412 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7414 * lisp.h: Remove empty conditional.
7416 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7418 * lread.c (load_path_check): Now static.
7420 Fix some minor --with-ns problems found by static checking.
7421 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7422 (x_set_font) [!HAVE_X_WINDOWS]:
7423 * image.c (xpm_load_image) [HAVE_NS]:
7424 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7425 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7426 Remove unused local.
7427 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7428 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7429 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7430 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7431 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7432 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7433 Fix pointer signedness problem.
7434 * xfaces.c (FRAME_X_FONT_TABLE):
7435 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7437 2012-07-07 Glenn Morris <rgm@gnu.org>
7439 * lread.c (load_path_check): New function, split from init_lread.
7440 (init_lread): Reorganize. Motivation:
7441 If EMACSLOADPATH is set, check/warn about that rather than the
7442 defaults, which we are not going to use. Hence we can remove
7443 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7444 Don't warn if site-lisp directories are missing.
7445 If not installed, start from a blank load-path, since
7446 PATH_LOADSEARCH refers to the eventual installation directories.
7448 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7450 Support truncation and continuation glyphs on GUI frames, when
7451 fringes are disabled. (Bug#11832)
7452 * xdisp.c (init_iterator): Get dimensions of truncation and
7453 continuation glyphs even if on GUI frames.
7454 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7455 or both, are absent.
7456 (start_display, move_it_in_display_line_to): Handle the case of a
7457 GUI frame without a fringe to display continuation or truncation
7459 (insert_left_trunc_glyphs): Support GUI frames: make sure
7460 truncation glyphs overwrite enough glyphs from the current line to
7461 have sufficient space in pixels.
7462 (display_line): Support truncation and continuation glyphs on GUI
7463 frames. If some spare pixels are left on the line after inserting
7464 the truncation glyphs, fill that space with a stretch glyph of a
7465 suitably computed width.
7467 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7468 produce_glyphs, to support GUI sessions.
7470 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7472 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7474 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7476 Do not require float-time's arg to fit in time_t (Bug#11825).
7477 This works better on hosts where time_t is unsigned, and where
7478 float-time is applied to the (negative) difference between two times.
7479 * editfns.c (decode_time_components): Last arg is now double *,
7480 not int *, and means to store all the result as a double, without
7481 worrying about whether the seconds part fits in time_t.
7482 All callers changed.
7483 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7484 All callers changed.
7485 (Ffloat_time): Do not fail merely because the specified time falls
7486 outside of time_t range.
7488 2012-07-07 Glenn Morris <rgm@gnu.org>
7490 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
7491 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
7492 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
7494 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
7496 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7497 Update dependencies.
7499 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7501 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7503 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

7505 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7506 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7507 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7508 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7510 * xfont.c (compare_font_names): Redo to omit the need for casts.
7512 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7514 * xfns.c (Fx_change_window_property): Doc fix.
7515 * w32fns.c (Fx_change_window_property): Doc fix.
7517 * w32fns.c (Fx_window_property): Accept the same arguments as the
7518 X Windows version. Doc fix.
7519 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7521 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7522 Eli Zaretskii <eliz@gnu.org>
7524 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7525 Windows-specific code from nt/config.nt moved here.
7526 Obsolete settings removed.
7528 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7530 * process.c: Avoid unnecessary calls to gettime.
7531 (wait_reading_process_output): Don't get the time of day
7532 when gobbling data immediately and not waiting, as there's no need
7533 for it in that case. This removes a FIXME.
7535 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7537 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7538 is defined (Bug#11768).
7540 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7542 Fix marker debugging code.
7543 * marker.c (byte_char_debug_check): Do not perform the check
7544 if buffer is not multibyte.
7545 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7546 Call byte_char_debug_check with correct arguments.
7548 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7550 Compile marker debugging code only if ENABLE_CHECKING is defined.
7551 * marker.c (byte_char_debug_check, count_markers):
7552 Use only if ENABLE_CHECKING is defined.
7553 (byte_debug_flag): Remove.
7554 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7555 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7557 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7559 Avoid code repetition in marker-related functions.
7560 * marker.c (attach_marker): New function.
7561 (Fset_marker, set_marker_restricted, set_marker_both)
7562 (set_marker_restricted_both): Use it.
7563 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7564 Consistently rename charno to charpos.
7565 (marker_position): Add eassert.
7566 (marker_byte_position): Convert to eassert.
7568 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

7579 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
7580 * composite.c (autocmp_chars): Likewise.

7582 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
7583 (save_restriction_save): Use build_marker.
7584 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
7585 * window.c (save_window_save): Likewise.
7587 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7589 Do not use Fdelete_overlay in delete_all_overlays
7590 to avoid redundant calls to unchain_overlay.
7591 * buffer.c (drop_overlay): New function.
7592 (delete_all_overlays, Fdelete_overlay): Use it.
7593 * minibuf.c (get_minibuffer): Fix comment.
7595 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7597 Port to OpenBSD 5.1 amd64.
7598 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7599 This is needed for OpenBSD, and should be harmless on all BSD systems.
7600 Also, include <sys/sysctl.h>, as it should be available on all
7601 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7602 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7603 use p_pid member, not kp_proc.pid.
7605 2012-07-06 Glenn Morris <rgm@gnu.org>
7607 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7609 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7611 More xmalloc and related cleanup.
7612 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
7613 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
7614 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
7615 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
7616 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
7617 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
7618 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
7619 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7620 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7622 Omit needless casts involving void * pointers and allocation.
7623 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7624 as the former is more robust if P's type is changed.
7625 Prefer xzalloc to xmalloc + memset 0.
7626 Simplify malloc-or-realloc to realloc.
7627 Don't worry about xmalloc returning a null pointer.
7628 Prefer xstrdup to xmalloc + strcpy.
7629 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7631 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7632 alloca of a constant.
7634 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7636 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7637 hscroll is larger than the line width. Fixes long and futile
7638 looping inside extend_face_to_end_of_line (on a TTY) producing
7639 glyphs that are not needed and thrown away.
7641 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7643 * marker.c (set_marker_restricted_both): Simplify by using

7653 not defined (Bug#11768).
7654 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
7655 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
7656 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
7657 followed by gtk_box_set_homogeneous (Bug#11768).
7658 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7659 (update_theme_scrollbar_width, xg_create_scroll_bar):
7660 Use gtk_scrollbar_new (Bug#11768).
7661 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

7669 * xdisp.c (window_hscroll_limited): New function.
7670 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7671 coordinates when window's hscroll is set to insanely large
7674 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7676 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
7677 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
7679 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7682 * lisp.h (xzalloc): New prototype. Omit needless casts.
7683 * alloc.c (xzalloc): New function. Omit needless casts.

7737 * fileio.c (time_error_value): Check the right error number.
7738 Problem reported by Troels Nielsen in
7739 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

7743 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7744 This should be fixed in a better way; see Eli Zaretskii in
7745 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7746 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7748 * fileio.c (time_error_value): Rename from special_mtime.
7749 The old name's problems were noted by Eli Zaretskii in
7750 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7752 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7753 This variable's comment says Emacs needs at least one GDB-visible
7754 symbol of type enum pvec_type, to work around GDB problems.
7755 The symbol's value doesn't matter.
7757 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7758 that causes compilation to fail on pre-C99 compilers.
7760 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7762 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
7763 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
7765 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7767 * buffer.c (init_buffer_once): Fix initialization of
7768 headers for buffer_defaults and buffer_local_symbols.
7769 Reported by Juanma Barranquero <lekktu@gmail.com>.
7771 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7773 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7774 * lisp.h (enum pvec_type): Use fewer bits.
7775 (PSEUDOVECTOR_SIZE_BITS): New constant.
7776 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7777 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7778 change in pvec_type.
7779 (PSEUDOVECTOR_TYPEP): New macro.
7780 (TYPED_PSEUDOVECTORP): Use it.
7781 * fns.c (internal_equal): Adapt code to extract pvectype.

7785 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7786 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7787 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7788 abusing vector->header.next.nbytes.
7789 (live_vector_p): Use PVEC_TYPE.
7790 (mark_object): Adapt code to extract pvectype. Use switch.
7792 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7794 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7795 Tighten new eassert a bit.
7797 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7799 Fix compilation with --enable-gcc-warnings and -O1
7801 * doprnt.c (doprnt): Change type of tem to int, initialize
7802 to avoid compiler warning. Add eassert.
7803 * search.c (simple_search): Initialize match_byte to avoid
7804 compiler warning. Add eassert.
7806 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7808 Avoid weird behavior with large horizontal scrolls.
7809 Without this change, for example, large hscroll values would
7810 mess up Emacs's display on Fedora 15 x86, presumably due to
7811 overflows in int calculations in the display code.
7812 Also, if buffers had long lines, Emacs would freeze.
7813 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7814 (set_window_hscroll): New function, containing the old guts of
7815 Fset_window_hscroll. Return the clipped value.
7816 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7817 This avoids the need to check against PTRDIFF_MAX.
7819 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7821 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7823 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7825 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7827 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7828 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7829 since GCC 4.4.6 issues a bogus warning for them.
7831 Fix bugs in file timestamp newness comparisons.
7832 * fileio.c (Ffile_newer_than_file_p):
7833 * lread.c (Fload): Use full timestamp resolution of files,
7834 not just the 1-second resolution, so that files that are only
7835 slightly newer still count as newer.
7836 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7837 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7839 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7841 * fileio.c: Improve handling of file time marker. (Bug#11852)
7842 (special_mtime): New function.
7843 (Finsert_file_contents, Fverify_visited_file_modtime):
7844 Use it to set special mtime values consistently.
7846 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7848 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7849 marker for non-existing file. (Bug#11852)
7851 2012-07-03 Glenn Morris <rgm@gnu.org>
7853 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7854 and did not make it into globals.h).
7856 2012-07-03 Tom Tromey <tromey@redhat.com>
7858 * window.c (Fset_window_margins, Fset_window_fringes)
7859 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7860 * textprop.c (Fprevious_property_change): No longer static.
7861 * syntax.c (Fsyntax_table_p): No longer static.

7883 * intervals.h: Remove EXFUNs.
7884 * fontset.h: Remove EXFUN.

7892 * xterm.h: Remove EXFUN.
7894 2012-07-03 Glenn Morris <rgm@gnu.org>
7896 * lisp.h (Frandom): Make it visible to C.
7897 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7898 buffer for invisible buffers. (Bug#1229)

7902 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7903 values which aren't power of 2.
7904 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7905 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7908 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7910 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7912 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7914 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7916 * alloc.c (allocate_vector_block): Remove redundant
7917 calls to mallopt if DOUG_LEA_MALLOC is defined.
7918 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7919 avoid calls to mallopt if zero_vector is returned.
7921 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7923 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7924 is enabled, avoid dereferencing NULL current_sblock if
7927 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7929 Cleanup basic buffer management.
7930 * buffer.h (struct buffer): Change layout to use generic vector
7931 marking code. Fix some comments. Change type of 'clip_changed'
7932 to bitfield. Remove unused #ifndef old.
7933 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7934 (GET_OVERLAYS_AT): Fix indentation.
7935 (for_each_per_buffer_object_at): New macro.

7939 * alloc.c (allocate_buffer): Adjust to match new layout of
7940 struct buffer. Fix comment.
7941 (mark_overlay): New function.

7944 (mark_object): Use it. Adjust marking of misc objects
7945 and related comments.
7947 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7949 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7950 wrapper that is not needed because the wrapped code is a no-op (zero
7951 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7952 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7954 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7956 * alloc.c (mark_buffer): Simplify. Remove prototype.
7957 (mark_object): Add comment. Reorganize marking of vector-like
7958 objects. Use CHECK_LIVE for all vector-like objects except buffers
7959 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7960 Avoid redundant calls to mark_vectorlike for bool vectors.
7962 2012-06-30 Glenn Morris <rgm@gnu.org>
7964 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7966 * epaths.in (PATH_SITELOADSEARCH): New.
7967 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7968 This is rather than relying on --enable-locallisppath elements
7969 having "site-lisp" in their names. (Bug#10208#25, 11658)
7971 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7973 * w32proc.c (sys_select): Accept and ignore one more argument.
7975 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7977 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7978 (pselect) [!MS_DOS]: Redirect to sys_select.
7980 * sysdep.c: Don't include dos.h and dosfns.h.
7982 * process.c (sys_select):
7983 * msdos.c (sys_select): Accept one more argument and ignore it.
7985 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7986 adapt data types and code to that.
7989 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7990 which clashes with the gnulib function of the same name.
7992 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7994 * font.c (font_style_to_value, font_style_symbolic)
7995 (font_prop_validate_style): Add type checks for values in
7998 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8000 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8003 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8005 * xdisp.c (try_window_id): Undo last change.
8007 * w32.c (getwd): Adjust commentary about startup_dir.
8008 (init_environment): Always call sys_access, even in non-MSVC
8009 builds. Don't chdir to the directory of the Emacs executable.
8010 This undoes code from 1997 which was justified by the need to
8011 "avoid conflicts when removing and renaming directories". But its
8012 downside was that every relative file name was being interpreted
8013 relative to the directory of the Emacs executable, which can never
8014 be TRT. In particular, it broke sys_access when called with
8015 relative file names.
8016 (sys_access): Map GetLastError to errno.
8018 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8020 * window.h (struct window): Change type of 'fringes_outside_margins'

8024 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8027 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8029 * gnutls.c (emacs_gnutls_handshake):
8030 Add QUIT to make the loop interruptible.
8032 2012-06-29 Glenn Morris <rgm@gnu.org>
8034 * charset.c (init_charset): Make lack of etc/charsets fatal.
8036 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8038 * editfns.c (region_limit): Fix type mismatch.
8040 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8042 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8043 undefined. Convert from xassert to eassert.
8044 * nsmenu.m: Convert from xassert to eassert.
8045 * nsterm.m: Likewise.
8047 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8049 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8051 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8053 Avoid integer overflow on scroll-left and scroll-right.
8054 * window.c (HSCROLL_MAX): New macro.
8055 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8056 overflow when requested scroll falls outside ptrdiff_t range.
8058 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8060 * window.h (struct window): Change type of 'hscroll',
8061 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8062 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8063 Adjust users accordingly.
8064 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8065 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8066 from EMACS_INT to ptrdiff_t.
8067 (make_window): Omit redundant initialization.
8069 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8071 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8073 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8075 * window.h (struct window): Change type of 'use_time' and
8076 'sequence_number' from Lisp_Object to int.
8077 * frame.c (make_frame): Adjust users accordingly.
8078 * print.c (print_object): Likewise.

8084 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
8085 enabled with --enable-checking=[all,glyphs] configure option.
8086 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8087 adjust comments accordingly.

8210 Use sprintf return value instead of invoking strlen on result.
8211 In the old days this wasn't portable, since some sprintf
8212 implementations returned char *. But they died out years ago and
8213 Emacs already assumes sprintf returns int.
8214 Similarly for float_to_string.
8215 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8223 Use sprintf or float_to_string result to avoid need to call strlen.
8224 * data.c (Fnumber_to_string):
8225 Use make_unibyte_string, since the string must be ASCII.
8226 * lisp.h, print.c (float_to_string): Now returns int length.
8227 * term.c (produce_glyphless_glyph):
8228 Use sprintf result rather than recomputing it.
8230 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8231 * Makefile.in (ALL_CFLAGS):
8232 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8261 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8263 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
8264 `const char *' to `char *' to avoid compiler warning.
8266 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8268 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8269 instead of truncating it to 63 (admittedly a generous limit).

8329 * keyboard.c (kbd_buffer_get_event):
8330 * process.c (Faccept_process_output):
8331 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8332 This improves on the previous patch, which introduced a bug
8333 when time_t is unsigned and as wide as intmax_t.
8334 See <http://bugs.gnu.org/9000#51>.
8336 2012-06-23 Eli Zaretskii <eliz@gnu.org>

8353 Privately reported by Herbert J. Skuhra.
8354 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

8365 language ID in the event parameters.
8367 * w32term.c (w32_read_socket): Put the new keyboard codepage into
8368 event.code, not the obscure "character set ID".

8399 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8401 Support higher-resolution time stamps (Bug#9000).
8402 The time stamps are only nanosecond-resolution at the C level,
8403 since that's the best that any real-world system supports now.
8404 But they are picosecond-resolution at the Lisp level, as that's
8405 easy, and leaves room for future OS improvements.
8407 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8410 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8411 Don't get current time unless it's needed.
8413 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8414 now provides it if it's absent.
8415 (start_atimer): Port to higher-res time stamps.
8416 Check for time stamp overflow. Don't get current time more
8417 often than is needed.
8419 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8420 Include systime.h, not time.h.
8421 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8423 * dired.c: Include stat-time.h.
8424 (Ffile-attributes): File times now have higher resolution.

8427 (struct image): Timestamp now has higher resolution.
8429 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8430 has at least microseconds now. All uses removed.
8431 (update_frame, update_single_window, update_window, update_frame_1)
8432 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8433 (duration_to_sec_usec): Remove; no longer needed.
8435 * editfns.c (time_overflow): Now extern.
8436 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8437 (float-time, Fformat_time_string, Fcurrent_time_string)

8441 (decode_time_components, lisp_seconds_argument): New functions.
8442 (make_time): Now static.
8443 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8444 Report an error if the time is invalid, rather than having the caller
8447 * fileio.c: Include <stat-time.h>
8448 (Fcopy_file): Copy higher-resolution time stamps.
8449 Prefer to set the time stamp via a file descriptor if that works.

8451 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8452 (Fvisited_file_modtime, Fset_visited_file_modtime):
8453 Support higher-resolution time stamps.
8455 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8457 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8459 * image.c (prepare_image_for_display, clear_image_cache)
8460 (lookup_image): Port to higer-resolution time stamps.
8462 * keyboard.c (start_polling, bind_polling_period):
8463 Check for time stamp overflow.
8464 (read_char, kbd_buffer_get_event, timer_start_idle)
8465 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8466 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8467 Port to higher-resolution time stamps. Do not assume time_t is signed.
8468 (decode_timer): New function. Timers are now vectors of length 9,
8469 not 8, to accommodate the picosecond component.
8470 (timer_check_2): Use it.
8472 * nsterm.m (select_timeout, timeval_subtract): Remove.
8473 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8474 as they're a bit more accurate and handle overflow better.
8475 (ns_select): Change prototype to be compatible with pselect.
8476 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8477 * nsterm.h (ns_select): Adjust prototype.
8479 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8480 us-resolution time stamps.
8481 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8483 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8485 * lisp.h (time_overflow): New decl.
8486 (wait_reading_process_output): First arg is now intmax_t, not int,
8487 to accommodate larger waits.
8489 * process.h (struct Lisp_Process.read_output_delay):
8490 Now counts nanoseconds, not microseconds.
8491 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8493 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8494 (wait_reading_process_output):
8495 Port to ns-resolution time stamps.
8496 (Faccept_process_output, wait_reading_process_output):
8497 Check for time stamp overflow. Do not assume time_t is signed.
8498 (select_wrapper): Remove; we now use pselect.
8499 (Fprocess_attributes): Now generates ns-resolution time stamps.
8501 * sysdep.c: Include utimens.h. Don't include utime.h
8502 or worry about struct utimbuf; gnulib does that for us now.
8503 (gettimeofday): Remove; gnulib provides a substitute.
8504 (make_timeval): New function.
8505 (set_file_times): Now sets ns-resolution time stamps.
8506 New arg FD; all uses changed.
8507 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8508 (system_process_attributes):
8509 Now returns ns-resolution time stamp. All uses changed.
8510 Check for time stamp overflow.
8512 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8513 provides a substitute now.
8515 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8516 since it guarantees struct timespec.
8517 (EMACS_TIME): Now struct timespec, so that we can support
8518 ns-resolution time stamps.
8519 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8520 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8521 (EMACS_USECS): Remove.
8522 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8523 so multiply the arg by 1000 before storing it.
8524 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8526 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8527 Port to ns-resolution time stamps.
8528 (EMACS_TIME_NEG_P): Remove; replaced by....
8529 (EMACS_TIME_SIGN): New macro.
8530 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8531 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

8533 (make_timeval, make_lisp_time, decode_time_components): New decls.
8534 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8535 that it mishandled time_t overflow. You can't compare by subtracting!
8536 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8537 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8539 * term.c: Include <sys/time.h>.
8540 (timeval_to_Time): New function, for proper overflow wraparound.
8541 (term_mouse_position, term_mouse_click): Use it.
8543 * undo.c (record_first_change): Support higher-resolution time stamps
8545 (Fprimitive_undo): Use them when restoring time stamps.
8547 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8548 (w32_get_internal_run_time):
8549 Port to higher-resolution Emacs time stamps.
8550 (ltime): Now accepts single 64-bit integer, as that's more convenient
8553 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8555 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8556 for compatibility with pselect. Support ns-resolution time stamps.
8558 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8560 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8561 Check for time stamp overflow, and support ns-resolution time stamps.
8563 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8564 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8565 (timeval_subtract): Remove; no longer needed.
8566 (XTflash, XTring_bell, x_wait_for_event):
8567 Port to ns-resolution time stamps. Don't assume time_t is signed.
8569 2012-06-22 Chong Yidong <cyd@gnu.org>
8571 * xdisp.c (x_consider_frame_title): Revert last change.
8573 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8575 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8576 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8577 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8578 staticidx goes up to 1597 out of 1600 = 0x640.)
8580 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8582 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8583 Otherwise, the umask might be mistakenly 0 while handling input signals.
8585 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
8587 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

8593 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
8594 access to `contents' member of Lisp_Vector objects with AREF and ASET

8852 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8853 Use an inline function on all platforms when using the union type,
8854 since this is simpler and 'static inline' can be used portably

8999 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9000 would mishandle a string argument "Xc" if X was a multibyte

9077 fields from Lisp_Object to bitfield. Adjust users accordingly.
9079 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9081 Pacify gcc -Wdouble-precision when using Xaw.
9082 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9083 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9084 Use 'float' consistently, rather than 'float' in most places
9085 and 'double' in a couple of places.
9087 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9089 * xdisp.c (handle_stop): Detect whether we have overlay strings
9090 loaded by testing it->current.overlay_string_index to be
9091 non-negative, instead of checking whether n_overlay_strings is
9092 positive. (Bug#11587)
9094 2012-05-31 Chong Yidong <cyd@gnu.org>
9096 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9098 * doc.c (Fsubstitute_command_keys): Doc fix.
9100 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9102 * search.c (search_buffer): Remove calls to
9103 r_alloc_inhibit_buffer_relocation, as it is now called by
9104 maybe_unify_char, which was the cause of relocation of buffer text
9107 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9109 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9110 for the duration of call to load_charset, to avoid problems with
9111 callers of maybe_unify_char that access buffer text through C
9114 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9115 decrement the inhibition flag, instead of just setting or
9118 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9120 Remove obsolete '#define static' cruft.
9121 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9122 This #undef was "temporary" in 2000; it is no longer needed
9123 now that '#define static' has gone away.
9124 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9125 (gray_bitmap_bits): Remove; no longer needed.
9126 All uses replaced with definiens.
9127 * xterm.c: Include "bitmaps/gray.xbm".
9129 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9131 Clean up __executable_start, monstartup when --enable-profiling.
9132 The following changes affect the code only when profiling.
9133 * dispnew.c (__executable_start): Rename from safe_bcopy.
9134 Define only on platforms that need it.
9135 * emacs.c: Include <sys/gmon.h> when profiling.
9136 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9137 (__executable_start): Remove decl, since lisp.h does it now.
9138 (safe_bcopy): Remove decl; no longer has that name.
9139 (main): Coalesce #if into single bit of code, for simplicity.
9140 Cast pointers to uintptr_t, since standard libraries want integers
9142 * lisp.h (__executable_start): New decl.
9144 2012-05-31 Glenn Morris <rgm@gnu.org>
9146 * image.c (Fimagemagick_types): Doc fix.
9148 2012-05-30 Jim Meyering <meyering@redhat.com>
9150 * callproc.c (Fcall_process_region): Include directory component
9151 in mkstemp error message (Bug#11586).
9153 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9155 * alloc.c, lisp.h (make_pure_vector): Now static.
9157 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

9162 * data.c (Fdefalias): Purify definition, except for keymaps.
9163 (Qdefun): Move from eval.c.
9164 * lisp.h (Qdefun): Remove.
9165 * lread.c (read1): Tiny simplification.
9167 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9169 Do not create empty overlays with the evaporate property (Bug#9642).
9170 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9171 Bug#9642, but explicitly check that the buffer the overlay would
9172 be moved to is live and rearrange lines to make sure that errors
9173 will not put the overlay in an inconsistent state.
9174 (Fdelete_overlay): Cosmetics.
9176 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9178 * w32term.c (my_bring_window_to_top): New function.
9179 (x_raise_frame): Use handle returned by DeferWindowPos, which
9180 could be different from the original one.
9181 Call my_bring_window_to_top instead of my_set_foreground_window.
9184 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9185 by calling BringWindowToTop.
9187 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9188 (WM_EMACS_END): Increase by one.
9190 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9192 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9193 This avoids undefined behavior that might cause the eassert
9194 to not catch an out-of-range value.
9196 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9198 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9199 Update dependencies.
9201 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9203 * bidi.c (bidi_mirror_char): Fix last change.
9205 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9207 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9208 when referring to sectname field in printf format.
9210 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9212 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9213 Only r_alloc_inhibit_buffer_relocation needed to be added;
9214 the others were already declared.
9216 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9217 before checking whether it's out of range. Put the check inside
9219 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9221 2012-05-27 Ken Brown <kbrown@cornell.edu>
9223 * callproc.c (Fcall_process): Restore a line that was accidentally
9224 commented out in the 2011-02-13 change (bug#11547).
9226 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9228 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9229 defined on ralloc.c.
9231 * buffer.c [REL_ALLOC]: Remove prototypes of
9232 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9233 they are now on lisp.h.
9235 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9237 * search.c (search_buffer): Use it to inhibit relocation of buffer
9238 text while re_search_2 is doing its job, because re_search_2 is
9239 passed C pointers to buffer text. (Bug#11519)
9241 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9244 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9245 state after an additional call to move_it_in_display_line_to, keep
9246 the values of it->max_ascent and it->max_descent found for the
9248 (pos_visible_p): Revert the comparison against bottom_y to what it
9249 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9252 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9254 Fix coding-related core dumps with gcc -ftrapv.
9255 The code was computing A - B, where A and B are pointers, and B is
9256 random garbage. This can lead to core dumps on platforms that
9257 have special pointer registers, and it also leads to core dumps on
9258 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9259 A - B only when B is initialized properly.
9260 * coding.c (coding_set_source, coding_set_destination): Return void.
9261 (coding_change_source, coding_change_destinations): New functions,
9262 with the old behaviors of coding_set_source and coding_set_destination.
9263 All callers that need an offset changed to use these new functions.
9265 2012-05-26 Glenn Morris <rgm@gnu.org>
9267 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9269 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9271 Extend mouse support on W32 text-mode console.
9272 * xdisp.c (draw_row_with_mouse_face):
9273 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9275 * w32console.c: Include window.h.
9276 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9278 (initialize_w32_display): Initialize mouse-highlight data.
9280 * w32inevt.c: Include termchar.h and window.h.
9281 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9282 moves, call note_mouse_highlight. If help_echo changed, call
9283 gen_help_event to produce help-echo message in the echo area.
9284 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9287 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9289 * lread.c (read1): Simplify slightly to avoid an overflow warning
9290 with GCC 4.7.0 on x86-64.
9292 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9294 * bidi.c (bidi_mirror_char): Revert last change: an int is
9295 definitely wide enough here.
9297 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9299 Fix integer width and related bugs (Bug#9874).
9300 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9301 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
9302 (string_bytes, check_sblock, allocate_string_data):
9303 (compact_small_strings, Fmake_bool_vector, make_string)

9305 (make_string_from_bytes, make_specified_string)
9306 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
9307 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9309 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9310 (allocate_pseudovector):
9311 Use int, not EMACS_INT, where int is wide enough.
9312 (inhibit_garbage_collection, Fgarbage_collect):
9313 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9314 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9315 int might not be wide enough.
9316 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9317 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
9318 (bidi_at_paragraph_end, bidi_find_paragraph_start)
9319 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9320 (bidi_level_of_next_char, bidi_move_to_visually_next):
9321 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9322 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9323 (Fkill_buffer, Fset_buffer_major_mode)
9324 (advance_to_char_boundary, Fbuffer_swap_text)
9325 (Fset_buffer_multibyte, overlays_at, overlays_in)
9326 (overlay_touches_p, struct sortvec, record_overlay_string)
9327 (overlay_strings, recenter_overlay_lists)
9328 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9329 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9330 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9331 (Foverlay_recenter, last_overlay_modification_hooks_used)
9332 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9333 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9334 (validate_region): Omit unnecessary test for b <= e,
9335 since that's guaranteed by the previous test.
9336 (adjust_overlays_for_delete): Avoid pos + length overflow.
9337 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9338 (report_overlay_modification):
9339 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9340 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9341 Omit pointer cast, which isn't needed anyway, and doesn't work
9342 after the EMACS_INT -> ptrdiff_t change.
9343 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9344 * buffer.h: Adjust decls to match defn changes elsewhere.
9345 (struct buffer_text, struct buffer):

9347 Use EMACS_INT, not int, where int might not be wide enough.
9348 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9349 not int, to avoid needless 32-bit limit on 64-bit hosts.
9350 (exec_byte_code): Use tighter memory-full test, one that checks
9351 for alloca overflow. Don't compute the address of the object just
9352 before an array, as that's not portable. Use EMACS_INT, not
9353 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9354 * callint.c (Fcall_interactively):
9355 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9356 * callproc.c (call_process_kill, Fcall_process):
9357 Don't assume pid_t fits into an Emacs fixnum.
9358 (call_process_cleanup, Fcall_process, child_setup):

9360 (call_process_cleanup, Fcall_process, delete_temp_file)
9361 (Fcall_process_region):
9362 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9363 (Fcall_process): Simplify handling of volatile integers.
9364 Use int, not EMACS_INT, where int will do.
9365 * casefiddle.c (casify_object, casify_region, operate_on_word)
9366 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9367 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9368 (casify_object): Avoid integer overflow when overallocating buffer.
9369 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9370 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9371 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9372 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9373 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9374 integers are now checked earlier. All uses replaced with XINT.
9376 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9377 For CCL_MapSingle, check that content and value are in int range.
9378 (ccl_driver, Fregister_code_conversion_map):
9379 Check that Vcode_version_map_vector is a vector.
9380 (resolve_symbol_ccl_program): Check that vector header is in range.
9381 Always copy the vector, so that we can check its contents reliably
9382 now rather than having to recheck each instruction as it's being
9383 executed. Check that vector words fit in 'int'.
9384 (ccl_get_compiled_code, Fregister_ccl_program)
9385 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9386 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9387 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9388 contents are in range.
9389 (Fccl_execute_on_string): Check that status is in range.
9390 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9391 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9392 Accept and return EMACS_INT, not int, because callers can pass values
9394 (c_string_width, strwidth, lisp_string_width, chars_in_text)
9395 (multibyte_chars_in_text, parse_str_as_multibyte)
9396 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
9397 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9398 (string_escape_byte8, Fget_byte):
9399 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9400 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9401 avoid mishandling large integers.
9402 * character.h: Adjust decls to match defn changes elsewhere.
9403 * charset.c (load_charset_map_from_file, find_charsets_in_text)
9404 (Ffind_charset_region):
9405 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9406 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
9407 (load_charset_map_from_vector, Fdefine_charset_internal):
9408 Don't assume fixnum fits in int.
9409 (load_charset_map_from_vector, Fmap_charset_chars):
9410 Remove now-unnecessary CHECK_NATNUMs.
9411 (Fdefine_charset_internal): Check ranges here, more carefully.
9412 Don't rely on undefined behavior with signed left shift overflow.
9413 Don't assume unsigned int fits into fixnum, or that fixnum fits
9414 into unsigned int. Don't require max_code to be a valid fixnum;
9415 that's not true for gb10830 4-byte on a 32-bit host. Allow
9416 invalid_code to be a cons, for the same reason. Require code_offset
9417 to be a character. Avoid int overflow if max_char is close
9419 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9420 this is intended anyway and avoids some undefined behavior.
9421 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9422 INDEX_TO_CODE_POINT, as that's what it expects.
9423 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9424 * charset.h (DECODE_CHAR): Return int, not unsigned;
9425 this is what was intended anyway, and it avoids undefined behavior.
9426 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9427 integer-overflow issues.
9428 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9429 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9430 where the argument is EMACS_INT, and this behavior is not intended.
9431 * chartab.c (Fmake_char_table, Fset_char_table_range)
9432 (uniprop_get_decoder, uniprop_get_encoder):
9433 Don't assume fixnum fits in int.
9434 * cmds.c (move_point): New function, that does the gist of
9435 Fforward_char and Fbackward_char, but does so while checking
9436 for integer overflow more accurately.
9437 (Fforward_char, Fbackward_char): Use it.
9438 (Fforward_line, Fend_of_line, internal_self_insert)
9439 (internal_self_insert):
9440 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9441 Fix a FIXME, by checking for integer overflow when calculating
9442 target_clm and actual_clm.

9473 (get_translation, handle_composition_annotation, consume_chars):
9474 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9475 (consume_chars): Rewrite to not calculate an address outside buffer.
9476 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
9477 Don't access memory outside of the args array.
9478 (Fdefine_coding_system_internal): Check for charset-id overflow.
9479 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
9480 result of ENCODE_CHAR.
9481 * coding.h: Adjust decls to match defn changes elsewhere.
9482 (struct coding_system):
9483 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10203 reference to image_cache->refcount.
10204 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10206 2012-05-17 Juri Linkov <juri@jurta.org>
10208 * search.c (Fword_search_regexp, Fword_search_backward)
10209 (Fword_search_forward, Fword_search_backward_lax)
10210 (Fword_search_forward_lax): Move functions to isearch.el
10211 (bug#10145, bug#11381).
10213 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10215 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10217 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10219 * lread.c (init_obarray): Declare Qt and Qnil as special.
10221 2012-05-14 Glenn Morris <rgm@gnu.org>
10223 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10224 Put "libexec" before "bin", for the sake of init_callproc_1.
10226 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10228 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10230 * unexaix.c: Port to more-recent AIX compilers.
10231 (report_error, report_error_1, make_hdr, copy_sym)
10232 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10233 Make arguments const char *, not char *, to avoid violations of C
10234 standard and to fix some AIX warnings reported by Gilles Pion.
10236 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10238 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10239 already have overlays loaded.
10240 (handle_single_display_spec): Before returning without displaying
10241 fringe bitmap, synchronize the bidi iterator with the main display
10242 iterator, by calling iterate_out_of_display_property.
10243 (iterate_out_of_display_property): Detect buffer iteration by
10244 testing that it->string is a Lisp string.
10245 (get_next_display_element): When the current object is exhausted,
10246 and there's something on it->stack, call set_iterator_to_next to
10247 proceed with what's on the stack, instead of returning zero.
10248 (set_iterator_to_next): If called at the end of a Lisp string,
10249 proceed to consider_string_end without incrementing string
10250 position. Don't increment display vector index past the end of
10251 the display vector. (Bug#11417)
10252 (pos_visible_p): Don't report a position visible when move_it_to
10253 stopped at the last line of window, which happens to be scanned
10254 backwards by the bidi iteration. (Bug#11464)
10256 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10258 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10259 and right-margin display specs even if the spec is invalid or we
10260 are on a TTY, and thus unable to display on the fringes.
10261 That's because the text with the property will not be displayed anyway,
10262 so we need to signal to the caller that this is a "replacing"
10263 display spec. This fixes display when the spec is invalid or we
10266 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10268 * unexaix.c (make_hdr): Fix typo in prototype.
10269 This bug broke the build on AIX. Problem reported by Gilles Pion.
10271 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10273 * keyboard.c (kbd_buffer_get_event): Read special events also in
10274 batch mode. (Bug#11415)
10276 2012-05-12 Glenn Morris <rgm@gnu.org>
10278 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10280 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10282 * lisp.mk (lisp): Add newcomment.elc.
10284 2012-05-12 Glenn Morris <rgm@gnu.org>
10286 * Makefile.in (MKDIR_P): New, set by configure.
10287 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10289 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10291 Remove unused function hourglass_started.
10292 * dispextern.h (hourglass_started):
10293 * w32fns.c (hourglass_started):
10294 * xdisp.c (hourglass_started): Remove.
10296 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10298 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10299 Update dependencies.
10301 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10303 * xgselect.c (xg_select): Put maxfds+1 into a var.
10304 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10306 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10308 2012-05-10 Dave Abrahams <dave@boostpro.com>
10310 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10311 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10313 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10315 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10316 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10317 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10318 Initialize xd_registered_buses.
10320 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10322 Untag more efficiently if USE_LSB_TAG.
10323 This is based on a proposal by YAMAMOTO Mitsuharu in
10324 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10325 For an admittedly artificial (nth 8000 longlist) benchmark on
10326 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10327 Emacs's overall text size by 1%.
10328 * lisp.h (XUNTAG): New macro.
10329 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10330 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10331 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10332 * eval.c (Fautoload):
10333 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10334 * frame.h (XFRAME): Use XUNTAG.
10336 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10337 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10338 Remove unportable assumptions about print widths of types like
10340 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10341 intptr_t when converting between pointer and integer, to avoid GCC
10342 warnings about wrong width.
10344 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10346 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10347 stack for each reader_thread, instead of defaulting to 8MB
10348 determined by the linker. This avoids failures in creating
10349 subprocesses on Windows 7, see the discussion in this thread:
10350 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10352 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10354 Fix up display of the *Minibuf-0* buffer in the mini window.
10355 * keyboard.c (read_char): Don't clear the echo area if there's no
10357 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10358 contents of *Minibuf-0*) if there's no message displayed in its stead.
10360 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10362 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10365 2012-05-06 Chong Yidong <cyd@gnu.org>
10367 * lisp.mk (lisp): Update.
10369 2012-05-05 Jim Meyering <meyering@redhat.com>
10371 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10373 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10375 * data.c (PUT_ERROR): New macro.
10376 (syms_of_data): Use it. Add new error type `user-error'.
10377 * undo.c (user_error): New function.
10378 (Fprimitive_undo): Use it.
10379 * print.c (print_error_message): Adjust print style for `user-error'.
10380 * keyboard.c (user_error): New function.
10381 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10383 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10385 Do not limit current-time-string to years 1000..9999.
10386 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10387 (Fcurrent_time_string): Support any year that is supported by the
10388 underlying localtime representation. Don't use asctime, as it
10389 has undefined behavior for years outside the range -999..9999.
10391 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10393 Fix race conditions involving setenv, gmtime, localtime, asctime.
10394 Without this fix, interrupts could mess up code that uses these
10395 nonreentrant functions, since setting TZ invalidates existing
10396 tm_zone or tzname values, and since most of these functions return
10397 pointers to static storage.
10398 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10399 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10400 Grow the critical sections to include not just invoking
10401 localtime/gmtime, but also accessing these functions' results
10402 including their tm_zone values if any, and any related TZ setting.
10403 (format_time_string): Last arg is now struct tm *, not struct tm **,
10404 so that the struct tm is saved in the critical section.
10405 All callers changed. Simplify allocation of initial buffer, partly
10406 motivated by the fact that memory allocation needs to be outside
10407 the critical section.
10409 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10411 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10412 with RESET_INTERVAL.
10414 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10415 Remove duplicated buffer name initialization.
10417 2012-05-02 Jim Meyering <jim@meyering.net>
10419 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10421 * xfns.c (x_window): Use xstrdup (Bug#11375).
10423 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10425 * xdisp.c (pos_visible_p): If already at a newline from the
10426 display string before the 'while' loop, don't walk back the glyphs
10427 from it3.glyph_row. Solves assertion violation when the display
10428 string begins with a newline (egg.el). (Bug#11367)
10430 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10432 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10435 2012-05-01 Glenn Morris <rgm@gnu.org>
10437 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10438 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10439 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10440 All were removed before 23.1.
10442 * dispnew.c: Remove HAVE_LIBNCURSES test;
10443 it is always true on relevant platforms.
10445 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10446 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10448 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10450 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10452 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10453 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10456 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10458 Do not avoid creating empty evaporating overlays (Bug#9642).
10459 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10460 That is, do not delete an evaporating overlay if it becomes
10461 empty after its bounds are adjusted to fit within its buffer.
10462 This fix caused other problems, and I'm reverting it until we get
10463 to the bottom of them.
10465 2012-04-27 Chong Yidong <cyd@gnu.org>
10467 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10469 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10471 * xdisp.c (pos_visible_p): If the window start position is beyond
10472 ZV, start the display from buffer beginning. Prevents assertion
10473 violation in init_iterator when the minibuffer window is scrolled
10474 via the scroll bar.
10476 * window.c (window_scroll_pixel_based): Likewise.
10478 2012-04-27 Chong Yidong <cyd@gnu.org>
10480 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10482 2012-04-27 Glenn Morris <rgm@gnu.org>
10484 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10485 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10487 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10489 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10490 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10492 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10494 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10495 display element, check also the underlying string or buffer
10496 character. (Bug#11341)
10498 * w32menu.c: Include w32heap.h.
10499 (add_menu_item): If the call to AppendMenuW (via
10500 unicode_append_menu) fails, disable Unicode menus only if we are
10501 running on Windows 9X/Me.
10503 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10505 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10506 (xgetint): Add missing shift for LSB tags.
10508 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10510 * keyboard.c (read_char): Don't wipe echo area for select window
10511 events: These might get delayed via `mouse-autoselect-window'
10514 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10516 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10517 manipulation of :loaded-from data.
10519 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10521 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10522 now a cons (bug#11311).
10524 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10526 Do not create empty overlays with the evaporate property (Bug#9642).
10527 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10528 if it becomes empty after its bounds are adjusted to fit within
10529 its buffer. Without this fix, in a nonempty buffer (let ((o
10530 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10531 yields an empty overlay that has the evaporate property, which is
10532 not supposed to happen.
10534 Fix minor GTK3 problems found by static checking.
10535 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10536 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10537 (struct _EmacsFixedClass, emacs_fixed_get_type):
10538 Move decls here from emacsgtkfixed.h, since they needn't be public.
10539 (emacs_fixed_get_type): Now static.
10540 (emacs_fixed_class_init): Omit unused local.
10541 (emacs_fixed_child_type): Remove; unused.
10542 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10543 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10544 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10545 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10546 (EMACS_FIXED_GET_CLASS): Remove; unused.
10547 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
10549 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
10550 Problem reported by Juanma Barranquero for Windows -Wunused-function.
10552 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10554 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10555 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10556 (__malloc_size_t, __malloc_ptrdiff_t):
10557 Remove. All uses removed, replaced by the definiens if needed,
10558 since we can assume C89 or better now.
10559 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

10567 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10568 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10569 Define using prototypes, not old style.
10570 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
10571 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
10572 (align): Don't assume that signed integer overflow wraps around.
10573 Omit unused local var.
10574 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
10575 (_free_internal_nolock, memalign, mallochook, reallochook):
10576 Omit no-longer-needed casts.
10577 (valloc): Use getpagesize, not __getpagesize.
10578 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
10579 (struct hdr): The 'magic' member is now size_t, not unsigned long.
10581 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
10583 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
10585 Move functions from C to Lisp. Make non-blocking method calls
10586 the default. Implement further D-Bus standard interfaces.
10588 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

10628 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10630 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
10631 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
10632 Do not assume ptrdiff_t is the same width as 'int'.
10634 * alloc.c: Handle unusual debugging option combinations.

10645 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
10647 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10649 * sysdep.c [__FreeBSD__]: Minor cleanups.
10650 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10651 Use Emacs indenting style more consistently. Avoid some casts.
10652 Use 'double' consistently rather than mixing 'float' and 'double'.

10670 * print.c (print_preprocess): Only check print_depth if print-circle
10672 (print_object): Check for cycles even when print-circle is nil and

10677 * process.c (wait_reading_process_output): If EIO occurs on a pty,
10678 set the status to "failed" and ensure that sentinel is run.
10680 2012-04-20 Glenn Morris <rgm@gnu.org>
10682 * process.c (Fset_process_inherit_coding_system_flag)
10683 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

10711 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
10712 -Wunused-result, -Wunused-variable. This should go away once
10713 the Emacs and Gnulib regex code is merged.
10714 (xmalloc, xrealloc): Now static.
10716 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

10733 New extern decls, to avoid calling undeclared functions.
10734 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
10735 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
10736 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10737 (NEED_MEM_INSERT): New macro.
10738 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10739 Remove one incorrect comment and fix another.

10754 Remove decls. This fixes an "It stinks!".
10756 * alloc.c (which_symbols): Fix alignment issue / type clash.
10758 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
10760 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
10761 (struct Lisp_Misc_Any): Likewise.
10762 (struct Lisp_Free): Likewise.

10774 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
10775 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10776 * s/netbsd.h, s/sol2-6.h:
10777 Remove definition of GC_MARK_STACK, since the default now works.
10778 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

10780 no longer the default.
10781 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
10783 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

10802 2012-04-13 Reuben Thomas <rrt@sc3d.org>
10804 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
10806 2012-04-11 Daniel Colascione <dancol@dancol.org>
10808 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10809 against is gone. It's better to use vfork now so that when Cygwin
10810 gains a new, working vfork, we use it automatically (bug#10398).
10812 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
10814 * window.c (save_window_save): Obey window-point-insertion-type.

10832 * w32.c (w32_delayed_load): Record the full path of the library
10833 being loaded (bug#10424).
10835 2012-04-09 Glenn Morris <rgm@gnu.org>
10837 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
10838 not just in the obarray, before snarfing them. (Bug#11036)

10855 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10856 attempts per process (connection).
10858 2012-04-09 Chong Yidong <cyd@gnu.org>
10860 * eval.c (Fuser_variable_p, user_variable_p_eh)

10862 (Fdefvar): Caller changed.
10864 * callint.c (Finteractive, Fcall_interactively):
10865 * minibuf.c (Fread_variable): Callers changed.
10867 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10869 * xdisp.c (set_cursor_from_row): If the display string appears in
10870 the buffer at position that is closer to point than the position
10871 after the display string, display the cursor on the first glyph of
10872 the display string. Fixes cursor display when a 'display' text
10873 property immediately follows invisible text. (Bug#11094)
10875 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10877 composite.c: use 'double' consistently
10878 * composite.c (get_composition_id): Use 'double' consistently
10879 instead of converting 'float' to 'double' and vice versa; this is
10880 easier to understand and avoids a GCC warning.
10882 2012-04-09 Glenn Morris <rgm@gnu.org>
10884 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10885 preparation for dumping it with emacs. (Bug#4789)

10907 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10908 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10909 objects, as mark_maybe_pointer will catch them otherwise.

10929 [!WINDOWSNT]: New macros.
10930 (init_libxml2_functions, libxml2_loaded_p): New functions.
10931 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10932 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10933 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10934 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10936 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10937 Call init_libxml2_functions before calling libxml2 functions.
10938 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10940 * emacs.c: Don't include libxml/parser.h.

10946 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10948 * indent.c (Fvertical_motion): If there is a display string at
10949 point, use it.vpos to compute how many lines to backtrack after
10950 move_it_to point. (Bug#11133)
10952 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10954 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10955 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10956 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10957 macros related to unification of CJK characters. For the details,
10958 see the discussion following the message here:
10959 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10961 2012-04-04 Chong Yidong <cyd@gnu.org>

10975 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10977 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10978 position we get to after a call to move_it_to fails the
10979 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10980 only if we wind up in a string from display property. (Bug#11063)
10982 * window.c (Fdelete_other_windows_internal): Invalidate the row
10983 and column information about mouse highlight, so that redisplay
10984 restores it after reallocating the glyph matrices. (Bug#7464)
10986 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10987 string comes from a `display' text property, use the buffer
10988 position of that property as if we actually saw that position in
10990 (move_it_by_lines): Remove the assertion that
10991 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10992 violated when there's a before-string at the beginning of a line.
10995 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10997 * xdisp.c (append_space_for_newline): If the default face was

11000 extending the face to the end of the line.
11001 (display_line): Call extend_face_to_end_of_line when the default
11002 face was remapped. (Bug#11068)

11050 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11052 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11053 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11054 when fetching a multibyte character consumes more bytes than
11055 CHAR_BYTES returns, due to unification of CJK characters in
11056 string_char. (Bug#11073)
11058 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11060 * process.c (wait_reading_process_output): Handle pty disconnect
11061 by refraining from sending oneself a SIGCHLD (bug#10933).

11095 that is not from display property, accept the row as a "cursor
11096 row" if one of the string's character has a non-nil `cursor'
11097 property. Fixes cursor positioning when there are newlines in
11098 overlay strings, e.g. in icomplete.el. (Bug#11035)
11100 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

11131 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11134 2012-03-03 Glenn Morris <rgm@gnu.org>
11136 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11138 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11140 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11141 position past the first glyph_row that ends at ZV. (Bug#10902)
11142 (redisplay_window, next_element_from_string): Fix typos in
11144 (redisplay_window): Pass to move_it_vertically the margin in
11145 pixels, not in screen lines.
11147 2012-03-02 Glenn Morris <rgm@gnu.org>
11149 * buffer.c (buffer-list-update-hook): Doc fix.
11151 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11153 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11154 push_it before setting up the iterator for the first overlay
11155 string, even if we have an empty string loaded.
11156 (next_overlay_string): If there's an empty string on the iterator
11157 stack, pop the stack. (Bug#10903)
11159 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11161 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11162 Suggested by Stefan Monnier in
11163 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11164 * alloc.c (widen_to_Lisp_Object): New static function.
11165 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11166 and widening them to Lisp_Objects. This would work even if
11167 USE_LSB_TAG is defined and wide integers are used, which might
11168 happen in a future version of Emacs.
11170 2012-02-25 Chong Yidong <cyd@gnu.org>
11172 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

11177 before saving to clipboard manager.
11179 2012-02-24 Chong Yidong <cyd@gnu.org>
11181 * keyboard.c (process_special_events): Handle all X selection
11182 requests in kbd_buffer, not just the next one (Bug#8869).
11184 2012-02-23 Chong Yidong <cyd@gnu.org>
11186 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11187 call when setting menu-bar-lines and tool-bar-lines parameters.
11188 (unwind_create_frame_1): New helper function.
11190 * window.c (inhibit_window_configuration_change_hook): New var.
11191 (run_window_configuration_change_hook): Obey it.
11192 (syms_of_window): Initialize it.

11209 when computing $valmask.
11211 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11212 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11213 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11214 It's useless in that case, and it can cause problems on hosts
11215 that allocate halves of EMACS_INT values separately.
11216 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11217 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11218 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11219 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11220 it avoids undefined behavior on hosts where shifting right by more
11221 than the word width has undefined behavior.
11223 2012-02-19 Chong Yidong <cyd@gnu.org>
11225 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11226 (Funhandled_file_name_directory, Ffile_name_as_directory)
11227 (Fdirectory_file_name, Fexpand_file_name)
11228 (Fsubstitute_in_file_name): Protect against invalid file handler
11229 return values (Bug#10845).
11231 2012-02-18 Eli Zaretskii <eliz@gnu.org>

11243 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11245 2012-02-15 Chong Yidong <cyd@gnu.org>
11247 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11248 marked as special. Also, starting docstrings with * is obsolete.

11263 2012-02-12 Chong Yidong <cyd@gnu.org>
11265 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11266 as that creates a dangerous corner case.
11268 * window.c (Fdelete_window_internal): Invalidate the mouse
11269 highlight (Bug#9904).
11271 2012-02-12 Glenn Morris <rgm@gnu.org>

11274 (Fx_get_selection_internal, Fx_disown_selection_internal)
11275 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
11276 * nsselect.m (Fx_own_selection_internal)
11277 (Fx_disown_selection_internal, Fx_selection_exists_p)
11278 (Fx_selection_owner_p, Fx_get_selection_internal):
11279 Sync docs and argument specs with the xselect.c versions.
11281 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

11301 2012-02-07 Chong Yidong <cyd@gnu.org>
11303 * buffer.c (Fbuffer_local_variables)
11304 (buffer_lisp_local_variables): Handle unbound vars correctly;
11305 don't let Qunbound leak into Lisp.
11307 2012-02-07 Glenn Morris <rgm@gnu.org>
11309 * image.c (Fimagemagick_types): Doc fix.
11311 * image.c (imagemagick-render-type): Change it from a lisp object
11312 to an integer. Move the doc here from the lisp manual.

11329 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11331 * w32.c (get_emacs_configuration_options):
11332 Include --enable-checking, if specified, in the return value.
11334 2012-02-04 Martin Rudalics <rudalics@gmx.at>
11336 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
11337 after rounding frame sizes. (Bug#9723)

11342 before BEGV. (Bug#10696)
11344 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11346 Handle overflow when computing char display width (Bug#9496).
11347 * character.c (char_width): Return EMACS_INT, not int.
11348 (char_width, c_string_width): Check for overflow when
11349 computing the width; this is possible now that individual
11350 characters can have unbounded width. Problem introduced
11351 by merge from Emacs 23 on 2012-01-19.

11375 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11377 (x_produce_glyphs): If the component of a composition is a null
11378 string, set it->pixel_width to 1 to avoid zero-width glyph.

11382 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11383 first 2 arguments are identical. This makes inserting large
11384 output from a subprocess an order of magnitude faster on
11385 MS-Windows, where all sbrk'ed memory is always contiguous.
11387 2012-01-31 Glenn Morris <rgm@gnu.org>

11482 2012-01-09 Eli Zaretskii <eliz@gnu.org>
11484 * xdisp.c (rows_from_pos_range): Accept additional argument
11485 DISP_STRING, and accept any glyph in a row whose object is that
11486 string as eligible for mouse highlight. Fixes mouse highlight of
11487 display strings from overlays. (Bug#10464)
11489 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
11491 emacs: fix an auto-save permissions race condition (Bug#10400)

11493 (Fmake_directory_internal): Use it.
11494 (do_auto_save_make_dir): Set it, instead of invoking chmod after

12004 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12005 is set, removing the need for VIRT_ADDRESS_VARIES.
12006 (PURE_P): Use a more-efficient implementation that needs just one

12009 to 4 (xorl, subq, cmpq, setbe).
12010 * alloc.c (pure): Always extern now, since that's the

12021 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12022 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12023 behave as if the cursor position were at the window margin.
12025 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12026 and the cursor position is out of bounds, behave as if the cursor
12027 position were at the window margin. (Bug#10075)
12029 2011-11-18 Chong Yidong <cyd@gnu.org>
12031 * window.c (Fwindow_combination_limit): Make first argument

12104 Fixes assertion violations in row_equal_p. (Bug#10035)
12106 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

12247 Otherwise, these inline functions do not conform to C99 and
12248 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12249 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12250 * intervals.c (adjust_intervals_for_insertion)

12253 (static_offset_intervals): Remove.
12254 (offset_intervals): Rewrite using the old contents of
12255 static_offset_intervals. The old version didn't conform to C99
12256 because an extern inline function contained a reference to an
12257 identifier with static linkage.

12504 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
12505 (Fmove_to_window_line): Doc fix.
12507 2011-10-27 Chong Yidong <cyd@gnu.org>
12509 * process.c (make_process): Set gnutls_state to NULL.
12511 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
12512 non-NULL, regardless of GNUTLS_INITSTAGE.
12513 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
12514 an error. Set process slots as soon as we allocate them.
12516 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
12518 2011-10-27 Chong Yidong <cyd@gnu.org>
12520 * gnutls.c (emacs_gnutls_deinit): New function.
12521 Deallocate credentials structures as well as calling gnutls_deinit.
12522 (Fgnutls_deinit, Fgnutls_boot): Use it.
12524 * process.c (make_process): Initialize GnuTLS credentials to NULL.
12525 (deactivate_process): Call emacs_gnutls_deinit.
12527 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12529 * image.c (x_create_x_image_and_pixmap):
12530 * w32.c (sys_rename, w32_delayed_load):
12531 * w32font.c (fill_in_logfont):

12534 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
12536 * w32fns.c (w32_default_color_map): New function,
12537 extracted from Fw32_default_color_map.
12538 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
12540 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
12542 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
12544 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
12546 * keyboard.c (test_undefined): New function (bug#9751).
12547 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
12549 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
12551 * sysdep.c (init_sys_modes): Fix the check for the controlling
12552 terminal (Bug#6649).
12554 2011-10-20 Eli Zaretskii <eliz@gnu.org>
12556 * dispextern.h (struct bidi_it): New member next_en_type.
12558 * bidi.c (bidi_line_init): Initialize the next_en_type member.
12559 (bidi_resolve_explicit_1): When next_en_pos is valid for the
12560 current character, check also for next_en_type being WEAK_EN.
12561 (bidi_resolve_weak): Don't enter the expensive loop if the current
12562 position is before next_en_pos. Record the bidi type of the first
12563 non-ET, non-BN character we find, in addition to its position.
12564 (bidi_level_of_next_char): Invalidate next_en_type when
12565 next_en_pos is over-stepped.
12567 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
12569 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12570 * editfns.c: Rewrite current-time-zone so that it invokes
12571 the equivalent of (format-time-string "%Z") to get the time zone name.
12572 This fixes a bug when the time zone name contains characters that
12573 need converting from the system time locale to Emacs internal format.
12574 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12575 that patch fixed format-time-string to do the conversion, but
12576 I forgot to fix current-time-zone.
12577 (format_time_string): New function, containing most of
12578 what Fformat_time_string used to contain.
12579 (Fformat_time_string): Rewrite in terms of format_time_string.
12580 This doesn't change this function's behavior.
12581 (current-time-zone): Rewrite to use format_time_string.
12582 This fixes the bug reported by Michael Schierl in
12583 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12584 Jason Rumney's 2007-06-07 change worked around this bug, but
12586 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12588 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12590 * xdisp.c (start_display): If the character at POS is displayed
12591 via a display vector, reset IT->current.dpvec_index to zero.
12592 (try_window_reusing_current_matrix): If a line ends in a display
12593 vector or the next line starts in a display vector, continue
12594 redrawing the window even though the character position of
12595 start_row was reached.
12598 2011-10-18 Chong Yidong <cyd@gnu.org>
12600 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12601 with nobreak-char-display too.
12603 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12605 Fix part 3 of bug#9771.
12606 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12607 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12608 non-neutral characters if the current character is a paragraph
12609 separator (a.k.a. Newline). This avoids running the same
12610 expensive loop twice, once when we consume the preceding newline
12611 and the other time when the line actually needs to be displayed.
12612 Avoid the loop when we see neutrals on the base embedding level
12613 following a character whose directionality is the same as the
12614 paragraph's. This avoids running the expensive loop when a line
12615 ends in a long sequence of neutrals, like control characters.
12616 Add assertion against STRONG_AL type. Slightly rearrange code
12617 that determines the type of a neutral given the first non-neutral
12619 (bidi_level_of_next_char): Set next_en_pos to zero when
12620 invalidating its info.
12622 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12624 * xdisp.c (push_display_prop): Determine whether to record string
12625 or buffer position by IT->string, not by IT->method. Allow
12626 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12627 (move_it_vertically_backward): Don't look for character position
12628 immediately after the newline when in a continuation line.
12631 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12633 * window.c (coordinates_in_window): Rewrite and delabelize
12634 vertical border check. (Bug#5357) (Bug#9618)
12636 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12638 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12639 errors in XSetWindowBorder (bug#9310).
12641 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12643 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12644 avoid crash when xmalloc overrun checking is enabled.
12646 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12648 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12649 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12650 cursor motion with <left> and <right> arrow keys.
12652 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12653 some callers set that themselves.
12655 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12657 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12658 display string and the previous row comes from the same string and
12659 is empty. (Bug#9739) (Bug#9738)
12661 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12663 * doc.c (get_doc_string): Encode file name (bug#9735).
12665 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12667 * bidi.c (bidi_level_of_next_char):
12668 * xdisp.c (get_visually_first_element): Remove old incorrect
12669 comments regarding the Unicode Line Separator character.
12671 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12673 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12675 * alloc.c (Fgc_status): Do not access beyond zombies array
12676 boundary if nzombies > MAX_ZOMBIES.
12677 * alloc.c (dump_zombies): Add missing format specifier.
12679 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12681 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12682 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12684 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12685 Some packages use them to denote characters with modifiers.
12687 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12689 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12690 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12691 matching a pp-number. Rename parameter var to var1.
12693 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12695 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12697 2011-10-08 Glenn Morris <rgm@gnu.org>
12699 * callint.c (Fcall_interactively): Give a more explicit error for the
12700 'c' case with a non-character input. (Bug#8479)
12702 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12704 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12706 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12707 lines that are hscrolled on the left.
12709 * dispnew.c (buffer_posn_from_coords): Account for a possible
12710 presence of header-line. (Bug#4426)
12712 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12714 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12715 Don't advertise functionality which we discourage or doesn't work.
12717 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12719 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12720 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12721 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12722 this makes Emacs dump core during garbage collection on rare
12723 occasions. sizeof is obviously inferior to offsetof here, so
12724 stick with offsetof.
12725 (GC_POINTER_ALIGNMENT): New macro.
12726 (mark_memory): Omit 3rd (offset) arg; caller changed.
12727 Don't assume EMACS_INT alignment is the same as pointer alignment.
12729 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12731 * keyboard.c (read_key_sequence_remapped): New var.
12732 (read_key_sequence): Compute remapping in the right buffer.
12733 (command_loop_1): Use read_key_sequence's remapping directly.
12735 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12737 * dired.c (file_name_completion): Don't expand file name.
12738 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12739 before checking file name handler.
12741 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12742 they've been requested explicitly (bug#9591).
12744 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12746 * keymap.c (Fsingle_key_description): Use make_specified_string
12747 instead of build_string to build string from push_key_description.
12750 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12752 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12753 This fixes a Y2038 bug on 64-bit hosts.
12754 * buffer.c (reset_buffer):
12755 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12756 (Fclear_buffer_auto_save_failure):
12757 Use 0, not -1, to represent an unset failure time, since time_t
12758 might not be signed.
12760 Remove dependency on glibc malloc internals.
12761 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12762 Move back here from lisp.h, but with their new implementations.
12763 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12764 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12765 * charset.c (charset_table_init): New static var.
12766 (syms_of_charset): Use it instead of xmalloc. This removes a
12767 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12768 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12769 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12770 Move back to alloc.c.
12771 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12772 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12774 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12776 * nsterm.m (windowDidResize): Call x_set_window_size only when
12777 ns_in_resize is true. Otherwise set pixelwidth/height and
12778 call change_frame_size (Bug#9628).
12780 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12782 Port --enable-checking=all to Fedora 14 x86-64.
12783 * charset.c (syms_of_charset): Also account for glibc malloc's
12784 internal overhead when calculating the initial malloc maximum.
12786 Port --enable-checking=all to Fedora 14 x86.
12787 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12789 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12790 (overrun_check_realloc, overrun_check_free):
12791 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12792 That way, xmalloc returns a properly-aligned pointer even if
12793 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12794 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12795 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12796 into account when calculating the initial malloc maximum.
12797 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12798 Move here from alloc.c, so that charset.c can use it too.
12799 Properly align; the old code wasn't right for common 32-bit hosts
12800 when configured with --enable-checking=all.
12801 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12802 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12804 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12806 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12809 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12811 * xdisp.c (compute_display_string_end): If there's no display
12812 string at CHARPOS, return -1.
12814 * bidi.c (bidi_fetch_char): When compute_display_string_end
12815 returns a negative value, treat the character as a normal
12816 character not covered by a display string. (Bug#9624)
12818 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12820 * lread.c (Fread_from_string): Fix typo in docstring.
12822 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12824 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12825 newline, reseat the iterator instead of bidi-iterating there one
12826 character at a time. (Bug#9610)
12827 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12828 TO_CHARPOS if the bidi iterator is at base embedding level.
12830 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12832 * lread.c (readevalloop): Use correct code for NBSP.
12833 (read1): Likewise. (Bug#9608)
12835 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12837 * dbusbind.c (Fdbus_register_signal): When service is not
12838 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12840 2011-09-25 Glenn Morris <rgm@gnu.org>
12842 * buffer.c (truncate-lines): Doc fix.
12844 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12846 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12847 (Fset_window_next_buffers): Doc fix.
12849 2011-09-24 Glenn Morris <rgm@gnu.org>
12851 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12853 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12855 Fix minor problems found by static checking.
12856 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12857 * indent.c (Fvertical_motion): Fix == vs = typo.
12859 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12861 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12862 Default value is now t. Doc fix.
12864 * indent.c (Fvertical_motion): Compute and apply the overshoot
12865 logic when moving up, not only when moving down. Fix the
12866 confusing name and values of the it_overshoot_expected variable;
12867 logic changes accordingly. (Bug#9254) (Bug#9549)
12869 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12870 CHARPOS is covered by a display string which includes newlines.
12871 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12872 is covered by a display string with embedded newlines.
12874 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12876 * dbusbind.c (Fdbus_register_signal): Add match rule to
12877 Vdbus_registered_objects_table. (Bug#9581)
12878 (Fdbus_register_method, Vdbus_registered_objects_table):
12881 2011-09-24 Jim Meyering <meyering@redhat.com>
12883 do not ignore write error for any output size
12884 The previous change was incomplete.
12885 While it makes emacs --batch detect the vast majority of stdout
12886 write failures, errors were still ignored whenever the output size is
12887 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12888 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12889 && echo FAIL: ignored write error
12890 FAIL: ignored write error
12891 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12892 && echo FAIL: ignored write error
12893 FAIL: ignored write error
12894 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12896 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12898 * emacs.c (Fkill_emacs): In noninteractive mode exit
12899 non-successfully if a write error occurred on stdout. (Bug#9574)
12901 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12903 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12906 * dispextern.h (struct it): Update the comment documenting what
12909 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12911 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12912 a display string, extend search for cursor position to end of row.
12913 (find_row_edges): If the row ends in a newline from a display
12914 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12915 Handle the case of a display string with multiple newlines.
12916 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12917 non-empty line. Fixes confusing cursor motion with arrow keys at
12918 the beginning of a line that starts with whitespace.
12920 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12922 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12925 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12927 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12928 boolean (Bug#9154).
12930 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12932 * xdisp.c (display_line): Record maximum and minimum buffer
12933 positions even if no glyphs were produced (e.g., by a zero-width
12934 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12935 buffer positions that will be removed from the glyph row because
12937 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12938 column is beyond frame width: don't subtract 1 "pixel" when
12939 computing width of the stretch.
12940 (reseat_at_next_visible_line_start): Undo the change made on
12941 2011-09-17 that saved paragraph information and restored it after
12942 the call to `reseat'. (Bug#9545)
12944 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12946 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12947 and turn window cursor on if cleared (Bug#9415).
12949 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12951 * search.c (boyer_moore): Take unibyte characters from pattern
12952 literally. (Bug#9458)
12954 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12956 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12958 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12960 Fix minor problem found by static checking.
12961 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12962 initialized, to pacify gcc -Wuninitialized.
12964 * fileio.c: Report proper errno when syscall falls.
12965 (Finsert_file_contents): Save and restore errno,
12966 so that report_file_error outputs the correct diagnostic.
12967 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12969 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12971 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12973 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12975 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12976 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12978 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12980 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12981 about the current paragraph and restore it after the call to reseat.
12983 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12984 (bidi_find_paragraph_start): Search back for paragraph beginning
12985 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12986 (bidi_move_to_visually_next): Only trigger paragraph-related
12987 computations when the last character is a newline or at EOB, not
12988 just any NEUTRAL_B. (Bug#9470)
12990 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12991 truncated lines if point is covered by a display string. (Bug#9524)
12993 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12995 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12996 (cons_to_x_long): New function.
12997 (lisp_data_to_selection_data): Use it. Correct the test for
12998 short-versus-long data; it was negated. Break out of vector
12999 loop, for efficiency, when a long datum is discovered.
13001 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13003 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13005 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13007 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13008 GCC PR/17406) by declaring this function with external scope.
13010 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13012 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13013 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13015 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13017 * editfns.c (Fformat): Correctly handle text properties on "%%".
13019 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13021 * xterm.c (x_draw_composite_glyph_string_foreground):
13022 * w32term.c (x_draw_composite_glyph_string_foreground):
13023 * term.c (encode_terminal_code):
13024 * composite.c (composition_update_it, get_composition_id):
13025 * xdisp.c (get_next_display_element)
13026 (fill_composite_glyph_string): Add comments about special meaning
13027 of TAB characters in a composition.
13029 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13031 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13032 This occurs when processing a multibyte format.
13033 Problem reported by Wolfgang Jenker.
13035 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13037 * xdisp.c (try_cursor_movement): Only check for exact match if
13038 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13040 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13042 Remove unused external symbols.
13043 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13044 * xdisp.c (calc_pixel_width_or_height): Now static.
13045 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13046 * indent.c (check_display_width):
13047 * w32term.c: Fix comment to match code.
13048 * xterm.c, xterm.h (x_catching_errors): Remove.
13050 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13052 * xselect.c: Use signed conversions more consistently (Bug#9498).
13053 (selection_data_to_lisp_data): Assume incoming selection data are
13054 signed integers, not unsigned. This is to be consistent with
13055 outgoing selection data, which was modified to use signed integers
13056 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13057 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13058 expects long, not unsigned long.
13060 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13062 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13063 computation of loop end. Reported by Johan Bockgård
13066 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13068 * frame.c (Fother_visible_frames_p): Function deleted.
13070 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13072 * indent.c (compute_motion): Process display vector front to back
13073 rather than the other way around. (Bug#2496)
13075 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13077 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13079 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13081 * minibuf.c (Fread_from_minibuffer): Doc fix.
13083 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13085 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13086 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13088 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13090 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13091 value for non-existent files.
13093 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13095 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13096 set its "size" to -1. This will set the modtime_size field of
13097 the corresponding buffer to -1, which is what
13098 verify-visited-file-modtime expects for files that do not exist.
13101 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13103 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13105 * lisp.h: ... from here. push_key_description is no longer
13106 defined in keyboard.c, so its declaration should not be in
13107 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13108 logically belongs with push_key_description.
13110 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13112 * buffer.h: Include <sys/types.h> instead of <time.h>.
13113 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13114 Problem reported by Herbert J. Skuhra.
13116 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13118 * xml.c (parse_region): Make the parsing work for
13119 non-comment-starting XML files again (bug#9144).
13121 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13123 * image.c (gif_load): Fix calculation of bottom and right corner.
13126 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13128 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13129 redisplay in small windows.
13131 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13133 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13135 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13137 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13138 Operate on live windows only.
13140 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13142 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13144 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13146 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13147 only under bidi iteration.
13149 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13151 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13153 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13155 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13156 Without this fix, the command to link temacs failed due to an
13157 undefined symbol __builtin_isnan. This is because
13158 /usr/include/iso/math_c99.h #defines isnan(x) to
13159 __builtin_isnan(x), but the bundled gcc, which identifies itself
13160 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13162 * floatfns.c (isnan): #undef, and then #define to a clone of
13164 (Fisnan): Always define, since it's always available now.
13165 (syms_of_floatfns): Always define isnan at the Lisp level.
13167 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13169 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13171 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13173 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13174 The previous code assumed that file offsets (off_t values) fit in
13175 EMACS_INT variables, which is not true on typical 32-bit hosts.
13176 The code messed up by falsely reporting buffer overflow in cases
13177 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13178 when "big" contains more than 2**29 bytes, even though this
13179 inserts just one byte and does not overflow the buffer.
13180 (Finsert_file_contents): Store file offsets as off_t
13181 values, not as EMACS_INT values. Check for overflow when
13182 converting between EMACS_INT and off_t. When checking for
13183 buffer overflow or for overlap, take the offsets into account.
13184 Don't use EMACS_INT for small values where int suffices.
13185 When checking for overlap, fix a typo: ZV was used where
13186 ZV_BYTE was intended.
13187 (Fwrite_region): Don't assume off_t fits into 'long'.
13188 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13190 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13192 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13194 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13196 sprintf-related integer and memory overflow issues (Bug#9412).
13198 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13199 (esprintf, exprintf, evxprintf): New functions.
13200 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13201 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13202 (modify_event_symbol): Do not assume that the length of
13203 name_alist_or_stem is safe to alloca and fits in int.
13204 (Fexecute_extended_command): Likewise for function name and binding.
13205 (Frecursion_depth): Wrap around reliably on integer overflow.
13206 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13207 since some callers pass EMACS_INT values.
13208 (Fsingle_key_description): Don't crash if symbol name contains more
13209 than MAX_ALLOCA bytes.
13210 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13211 (get_minibuffer): Arg is now EMACS_INT, not int.
13212 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13213 (esprintf, exprintf, evxprintf): New decls.
13214 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13216 * dbusbind.c (signature_cat): New function.
13217 (xd_signature, Fdbus_register_signal):
13218 Do not overrun buffer; instead, report string overflow.
13220 * dispnew.c (add_window_display_history): Don't overrun buffer.
13221 Truncate instead; this is OK since it's just a log.
13223 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13224 even if the time zone offset is outlandishly large.
13225 Don't mishandle offset == INT_MIN.
13227 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13228 when creating daemon; the previous buffer-overflow check was incorrect.
13230 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13231 which has the guts of the old verror function.
13233 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13234 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13236 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13237 (font_unparse_xlfd): Don't blindly alloca long strings.
13238 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13239 fits in int, when using sprintf. Use single snprintf to count
13240 length of string rather than counting it via multiple sprintfs;
13241 that's simpler and more reliable.
13242 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13243 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13244 sprintf, in case result does not fit in int.
13246 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13247 (fontset_from_font): Print it.
13249 * frame.c (tty_frame_count): Now printmax_t, not int.
13250 (make_terminal_frame, set_term_frame_name): Print it.
13251 (x_report_frame_params): In X, window IDs are unsigned long,
13252 not signed long, so print them as unsigned.
13253 (validate_x_resource_name): Check for implausibly long names,
13254 and don't assume name length fits in 'int'.
13255 (x_get_resource_string): Don't blindly alloca invocation name;
13256 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13259 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13260 (xg_check_special_colors, xg_set_geometry):
13261 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13263 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13264 Use esprintf, not sprintf, in case result does not fit in int.
13266 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13267 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13268 it as a large positive number.
13269 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13270 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13272 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13273 in case result does not fit in int.
13275 * print.c (float_to_string): Detect width overflow more reliably.
13276 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13277 buffer overrun. Don't assume list length fits in 'int'. Treat
13278 print length of 0 as 0, not as infinity; to be consistent with other
13279 uses of print length in this function. Don't overflow print length
13280 index. Don't assume hash table size fits in 'long', or that
13281 vectorlike size fits in 'unsigned long'.
13283 * process.c (make_process): Use printmax_t, not int, to format
13284 process-name gensyms.
13286 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13288 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13289 to avoid potential buffer overrun.
13291 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13292 if X resource line is longer than 512 bytes.
13294 * xfns.c (x_window): Make sprintf buffer a bit bigger
13295 to avoid potential buffer overrun.
13297 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13299 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13301 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13303 Integer overflow fixes for scrolling, etc.
13304 Without these, Emacs silently mishandles large integers sometimes.
13305 For example, "C-u 4294967297 M-x recenter" was treated as if
13306 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13308 * xdisp.c (try_window_id): Check Emacs fixnum range before
13309 converting to 'int'.
13311 * window.c (window_scroll_line_based, Frecenter):
13312 Check that an Emacs fixnum is in range before assigning it to 'int'.
13313 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13314 values converted from Emacs fixnums.
13315 (Frecenter): Don't wrap around a line count if it is out of 'int'
13316 range; instead, treat it as an extreme value.
13317 (Fset_window_configuration, compare_window_configurations):
13318 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13320 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13321 that can exceed INT_MAX. Check that EMACS_INT value is in range
13322 before assigning it to the (possibly-narrower) index.
13323 (match_limit): Don't assume that a fixnum can fit in 'int'.
13325 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13328 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13329 (Fvertical_motion): Don't wrap around LINES values that don't fit
13330 in 'int'. Instead, treat them as extreme values. This is good
13331 enough for windows, which can't have more than INT_MAX lines anyway.
13333 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13335 * Require libxml/parser.h to avoid compilation warning.
13337 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13339 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13340 since this reportedly can destroy thread storage.
13342 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13344 * syntax.c (find_defun_start): Update all cache variables if
13345 exiting early (Bug#9401).
13347 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13349 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13351 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13352 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13353 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13355 * term.c (tty_append_glyph): New function.
13356 (produce_stretch_glyph): Static function and its prototype deleted.
13358 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13361 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13363 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13364 when checking :margin (Bug#9390).
13365 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13366 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13367 so that the name doesn't mislead. All uses changed.
13369 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13371 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13374 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13376 * xdisp.c (move_it_to): Don't bail out early when reaching
13377 position beyond to_charpos, if we are scanning backwards.
13378 (move_it_vertically_backward): When DY == 0, make sure we get to
13379 the first character in the line after the newline.
13381 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13383 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13384 (ccl_driver): Do not generate an out-of-range pointer.
13385 (Fccl_execute_on_string): Remove unnecessary check for
13386 integer overflow, noted by Stefan Monnier in
13387 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13388 Remove a FIXME that didn't need fixing.
13389 Simplify the newly-introduced buffer reallocation code.
13391 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13393 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13395 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13397 Integer and memory overflow issues (Bug#9196).
13399 * doc.c (get_doc_string): Rework so that
13400 get_doc_string_buffer_size is the actual buffer size, rather than
13401 being 1 less than the actual buffer size; this makes xpalloc more
13404 * image.c (x_allocate_bitmap_record, cache_image):
13405 * xselect.c (Fx_register_dnd_atom):
13406 Simplify previous changes by using xpalloc.
13408 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13409 since either will do and ptrdiff_t is convenient with xpalloc.

13419 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13421 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13422 The actual value is always <= INT_MAX, and leaving it unsigned made

13426 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13427 with xpalloc. The values are still always <= INT_MAX.

13437 (revalidate_region_cache, know_region_cache, region_cache_forward)
13438 (region_cache_backward, pp_cache):
13439 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13440 so that ptrdiff_t * can be passed to xpalloc.
13441 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13442 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

13457 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13459 Don't update size of array until after memory allocation succeeds,
13460 because xmalloc/xrealloc may not return.
13461 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13462 now that we have proper integer overflow checking.
13463 (record_overlay_string, overlay_strings): Catch overflows when
13464 calculating size of overlay_str_buf.
13466 * callproc.c (Fcall_process): Check for size overflow when
13467 calculating size of args2.
13468 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13469 Normally we prefer signed values, but sticking with ptrdiff_t would
13470 require adding more-complicated checks.
13472 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13473 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13474 Redo buffer-overflow calculations to avoid integer overflow.
13475 Add a FIXME comment where memory seems to be over-allocated.
13477 * character.c (Fstring): Check for size-calculation overflow.
13479 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid

13513 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13515 * emacs.c (main): Do not reallocate argv, since there is a null at
13516 the end that can be overwritten, and this way there's no need to
13517 worry about size-calculation overflow.
13518 (sort_args): Check for size-calculation overflow.
13520 * eval.c (init_eval_once, grow_specpdl): Don't update size until

13526 Check for integer overflow.
13527 (x_set_alpha): Do not assume XINT fits in int.
13529 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13530 This is for the members text_lines, text_cols, total_lines, total_cols,
13531 where the system imposes an 'int' limit.
13533 * fringe.c (Fdefine_fringe_bitmap):
13534 Don't update size until alloc works.

13539 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
13540 Check for size-calculation overflow.
13541 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13542 do, as we prefer signed integers.

13549 * gtkutil.h: Change prototypes to match the above.
13551 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

13598 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13599 for command line length. Do not attempt to address one before the
13600 beginning of an array, as that's not portable.

13646 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13647 (X_LONG_MIN): New macros.
13648 Use them to make the following changes clearer.
13649 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13650 This change doesn't affect the value now, but it may help remind
13651 future maintainers not to raise the value too much later.
13652 (SELECTION_QUANTUM): Remove, replacing with ...
13653 (selection_quantum): ... new function, which avoids overflow.
13655 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13656 assumption that selection length fits in 'int'.

13673 Don't store size until memory allocation succeeds.
13674 (x_get_window_property): Plug memory leak on memory exhaustion.
13675 Don't double-block input; malloc is safe here. Don't assume 2**34
13676 - 4 fits in unsigned long. Add an xassert to check
13677 XGetWindowProperty overflow. Be more careful about overflow
13678 calculations, and distinguish size from memory overflow better.
13679 (receive_incremental_selection): When tracing, don't assume
13680 unsigned int is less than INT_MAX.
13681 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

13684 in the range -65535 through -1 fit in an X unsigned short.
13685 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13686 result parameters unless successful. Rely on cons_to_unsigned
13687 to report problems with elements; the old code wasn't right anyway.
13688 (x_check_property_data): Check for int overflow; we cannot use
13689 a wider type due to X limits.

13722 * lisp.h (hash_lookup, hash_put):
13723 * minibuf.c (Ftest_completion):
13724 Use ptrdiff_t for hash table indexes, not int (which is too
13725 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

13728 * charset.c (Fdefine_charset_internal): Check for integer overflow.
13729 Add a FIXME comment about memory leaks.

13737 with outlandish widths.
13738 * character.h (sanitize_tab_width): Rename from sanitize_width,
13739 now that we have two such functions. All uses changed.

13764 (make_lispy_movement): Use same integer type in forward decl
13765 that is used in the definition.

13767 Change bufsize argument back to int, undoing my 2011-03-30 change.
13768 We prefer signed types, and int is wide enough here.
13769 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13770 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13771 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13772 length, not size_t. Use ptrdiff_t for index, not int.
13773 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13774 possibility of integer overflow.

13802 Prefer int to unsigned where either will do.
13803 (tiff_handler): New function, combining the cores of the
13804 old tiff_error_handler and tiff_warning_handler.
13805 This function is rewritten to use vsnprintf and thereby avoid
13806 stack buffer overflows. It uses only the features of vsnprintf
13807 that are common to both POSIX and native Microsoft.
13808 (tiff_error_handler, tiff_warning_handler): Use it.
13809 (tiff_load, gif_load, imagemagick_load_image):
13810 Don't assume :index value fits in 'int'.

13813 the integer types that MagickCropImage accepts. Don't assume
13814 Vimagemagick_render_type has a nonnegative value. Don't assume
13815 size_t fits in 'long'.
13816 (gs_load): Use printmax_t to print the widest integers possible.

13833 (try_cursor_movement): Check for the need to scroll more
13834 accurately, and prefer exact match for point under bidi.
13835 Don't advance `row' beyond the last row of the window.

13853 buffers, return left-to-right.
13854 (set_cursor_from_row): Consider candidate row a win if its glyph
13855 represents a newline and point is on that newline. Fixes cursor
13856 positioning on the newline at EOL of R2L text within L2R
13857 paragraph, and vice versa.
13858 (try_cursor_movement): Check continued rows, in addition to
13859 continuation rows. Fixes unwarranted scroll when point enters a
13860 continued line of R2L text within an L2R paragraph, or vice versa.
13861 (cursor_row_p): Consider the case of point being equal to
13862 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

13888 * xdisp.c (redisplay_window): When computing centering_position,
13889 account for the height of the header line. (Bug#8874)
13891 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13892 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13893 candidate is selected by the mouse, and that candidate has a
13894 composed character under the mouse.
13896 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13897 coordinates reported by pos-visible-in-window-p for a composed
13898 character in column zero.
13900 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

13907 consider it a hit if to_charpos is anywhere in the range of the
13908 composed buffer positions.
13910 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13912 * image.c (gif_load): Don't assume that each subimage has the same
13913 dimensions as the base image. Handle disposal method that is
13914 "undefined" by the gif spec (Bug#9335).
13916 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13918 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

13921 2011-08-19 Eli Zaretskii <eliz@gnu.org>
13923 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
13924 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13925 from an Org mode buffer to a Speedbar frame.
13927 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13928 a composition, take its buffer position from IT->cmp_it.charpos.
13929 Fixes cursor positioning at the beginning of a line that begins
13930 with a composed character.
13932 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13934 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13935 character bidirectional type, use STRONG_L instead. Fixes crashes
13936 in a buffer produced by `describe-categories'.
13938 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13939 members before the level stack, so they would be saved and
13940 restored when copying iterator state. Fixes incorrect reordering
13941 around TABs covered by display properties.
13943 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
13945 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14015 * xdisp.c (move_it_in_display_line_to): Don't invoke
14016 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14017 ppos_it. Fixes vertical cursor motion when line beginning is
14018 covered by an image. (Bug#9296)

14029 the event loop. Get status from as_status (Bug#7276).
14031 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14032 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14033 the event loop (Bug#7276).
14035 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14037 * gnutls.c (QCgnutls_bootprop_priority)

14059 (Fnetwork_interface_list): Allocate in increments of bytes instead
14060 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14061 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14063 (struct ifflag_def): notrailers is smart on OSX.
14064 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14065 Get hardware address with getifaddrs if available.

14069 * xdisp.c (iterate_out_of_display_property): xassert that
14070 IT->position is set to within IT->object's boundaries. Break from
14071 the loop as soon as EOB is reached; avoids infloops in redisplay

14073 Set IT->current to match the bidi iterator unconditionally.
14074 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14075 entry. Force push_it to save on the stack the current
14076 buffer/string position, to be restored by pop_it. Fix flags in
14077 the iterator structure wrt the object coming from a display
14078 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14079 properties. (Bug#9284)
14081 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14083 * fontset.c (fontset_get_font_group): Add proper type checks.

14122 longlines-mode. (Bug#9254)
14123 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14124 word-wrap under bidirectional display. (Bug#9224)
14126 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14127 is non-zero, even if the data buffer is NULL. Fixes a crash in
14128 vertical-motion with longlines-mode. (Bug#9254)
14130 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14132 * bidi.c <bidi_cache_total_alloc>: Now static.

14138 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14139 amount allocated this far in `bidi_cache_total_alloc'.
14140 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14141 non-zero, only free the data buffer without restoring the cache
14142 contents. All callers changed.
14144 * dispextern.h (bidi_unshelve_cache): Update prototype.
14146 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

14148 (move_it_vertically_backward, move_it_by_lines): Replace the call
14149 to xfree to an equivalent call to bidi_unshelve_cache.
14150 (move_it_in_display_line_to): Fix logic of returning
14151 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

14207 DISP_PROP_P, and pass it to compute_display_string_pos.
14208 Only handle text covered by a display string if DISP_PROP_P is returned
14209 non-zero. All callers of bidi_fetch_char changed.

14313 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14315 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14317 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14319 Integer signedness and overflow and related fixes. (Bug#9079)
14321 * bidi.c: Integer size and overflow fixes.
14322 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14323 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14324 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14325 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14326 (bidi_find_other_level_edge):
14327 Use ptrdiff_t instead of EMACS_INT where either will do.
14328 This works better on 32-bit hosts configured --with-wide-int.
14329 (bidi_cache_ensure_space): Check for size-calculation overflow.
14330 Use % rather than repeated addition, for better worst-case speed.
14331 Don't set bidi_cache_size until after xrealloc returns, because it
14333 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14334 (bidi_cache_ensure_space): Also check that the bidi cache size
14335 does not exceed that of the largest Lisp string or buffer. See Eli
14336 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14338 * alloc.c (__malloc_size_t): Remove.
14339 All uses replaced by size_t. See Andreas Schwab's note
14340 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14342 * image.c: Improve checking for integer overflow.
14343 (check_image_size): Assume that f is nonnull, since
14344 it is always nonnull in practice. This is one less thing to
14345 worry about when checking for integer overflow later.
14346 (x_check_image_size): New function, which checks for integer
14347 overflow issues inside X.
14348 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14349 This removes the need for a memory_full check.
14350 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14351 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14352 (xbm_read_bitmap_data): Change locals back to 'int', since
14353 their values must fit in 'int'.
14354 (xpm_load_image, png_load, tiff_load):
14355 Invoke x_create_x_image_and_pixmap earlier,
14356 to avoid much needless work if the image is too large.
14357 (tiff_load): Treat overly large images as if
14358 x_create_x_image_and_pixmap failed, not as malloc failures.
14359 (gs_load): Use x_check_image_size.
14361 * gtkutil.c: Omit integer casts.
14362 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14363 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14365 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14367 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14368 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14369 would wrongly return t on a 64-bit host.
14371 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14372 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14373 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14374 and therefore cause GCC to emit a bogus diagnostic in some cases.
14376 * image.c: Integer signedness and overflow and related fixes.
14377 This is not an exhaustive set of fixes, but it's time to
14378 record what I've got.
14379 (lookup_pixel_color, check_image_size): Remove redundant decls.
14380 (check_image_size): Don't assume that arbitrary EMACS_INT values
14381 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14382 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14383 (tiff_load, imagemagick_load_image):
14384 Check for overflow in size calculations.
14385 (x_create_x_image_and_pixmap): Remove unnecessary test for
14386 xmalloc returning NULL; that can't happen.
14387 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14388 (xpm_color_bucket): Use better integer hashing function.
14389 (xpm_cache_color): Don't possibly over-allocate memory.
14390 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14391 (gif_memory_source):
14392 Use ptrdiff_t, not int or size_t, to record sizes.
14393 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14394 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14395 either works, as we prefer signed integers.
14396 (tiff_read_from_memory, tiff_write_from_memory):
14397 Return tsize_t, not size_t, since that's what the TIFF API wants.
14398 (tiff_read_from_memory): Don't fail simply because the read would
14399 go past EOF; instead, return a short read.
14400 (tiff_load): Omit no-longer-needed casts.
14401 (Fimagemagick_types): Don't assume size fits into 'int'.
14403 Improve hashing quality when configured --with-wide-int.
14404 * fns.c (hash_string): New function, taken from sxhash_string.
14405 Do not discard information about ASCII character case; this
14406 discarding is no longer needed.
14407 (sxhash-string): Use it. Change sig to match it. Caller changed.
14408 * lisp.h: Declare it.
14409 * lread.c (hash_string): Remove, since we now use fns.c's version.
14410 The fns.c version returns a wider integer if --with-wide-int is
14411 specified, so this should help the quality of the hashing a bit.
14413 * emacs.c: Integer overflow minor fix.
14414 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14415 Define only if GNU_LINUX.
14416 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14418 * dispnew.c: Integer signedness and overflow fixes.
14419 Remove unnecessary forward decls, that were a maintenance hassle.
14420 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14422 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14423 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14424 (prepare_desired_row, line_draw_cost):
14425 Use int, not unsigned, where either works.
14426 (save_current_matrix, restore_current_matrix):
14427 Use ptrdiff_t, not size_t, where either works.
14428 (init_display): Check for overflow more accurately, and without
14429 relying on undefined behavior.
14431 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14432 Remove, replacing with the new symbols in lisp.h. All uses changed.
14433 * fileio.c (make_temp_name):
14434 * filelock.c (lock_file_1, lock_file):
14435 * xdisp.c (message_dolog):
14436 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14437 Use pMd etc. instead.
14438 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14439 replacing the pWIDE etc. symbols removed from editfns.c.
14441 * keyboard.h (num_input_events): Now uintmax_t.
14442 This is (very slightly) less likely to mess up due to wraparound.
14445 * buffer.c: Integer signedness fixes.
14446 (alloc_buffer_text, enlarge_buffer_text):
14447 Use ptrdiff_t rather than size_t when either will do, as we prefer
14450 * alloc.c: Integer signedness and overflow fixes.
14451 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14452 (__malloc_size_t): Default to size_t, not to int.
14453 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14454 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14455 Prefer ptrdiff_t to size_t when either would do, as we prefer
14457 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14458 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14459 Now const. Initialize with values that are in range even if char
14461 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14462 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14463 These functions do the right thing with sizes > 2**32.
14464 (check_depth): Now ptrdiff_t, not int.
14465 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14466 Adjust to new way of storing sizes. Check for size overflow bugs
14468 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14469 slightly wrong anyway, as it missed one instance of
14470 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14471 (refill_memory_reserve): Omit needless cast to size_t.
14472 (mark_object_loop_halt): Mark as externally visible.
14474 * xselect.c: Integer signedness and overflow fixes.
14475 (Fx_register_dnd_atom, x_handle_dnd_message):
14476 Use ptrdiff_t, not size_t, since we prefer signed.
14477 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14478 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14479 x_dnd_atoms_size and x_dnd_atoms_length.
14481 * doprnt.c: Prefer signed to unsigned when either works.
14483 * doprnt.c (doprnt):
14485 * xdisp.c (vmessage):
14486 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14487 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14488 prefer signed arithmetic to avoid comparison confusion.
14489 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14490 but is a bit tricky.
14492 Assume freestanding C89 headers, string.h, stdlib.h.
14493 * data.c, doprnt.c, floatfns.c, print.c:
14494 Include float.h unconditionally.
14495 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14496 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14497 * regex.c: Likewise for stddef.h, string.h.
14498 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14499 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14500 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14501 (STDC_HEADERS): Remove obsolete defines.
14502 * sysdep.c: Include limits.h unconditionally.
14504 Assume support for memcmp, memcpy, memmove, memset.
14505 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14506 * regex.c (memcmp, memcpy):
14507 Remove; we assume C89 now.
14509 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14510 (__malloc_safe_bcopy): Remove; no longer needed.
14512 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14513 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14514 well either way, and we prefer signed to unsigned.
14516 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14518 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14519 closes the connection while we're reading (bug#9182).
14521 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14523 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14524 are specified (Bug#9168).
14526 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14528 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14529 Found by GCC static checking and --with-wide-int on a 32-bit host.
14531 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14533 * xdisp.c (compute_display_string_pos): Fix logic of caching
14534 previous display string position. Initialize cached_prev_pos to
14535 -1. Fixes slow-down at the beginning of a buffer.
14537 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14539 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14540 for attrs[LFACE_FONTSET_INDEX].
14542 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14544 * xml.c (parse_region): Remove unused local
14545 that was recently introduced.
14547 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14549 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14550 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14552 * xdisp.c (move_it_in_display_line_to): Record the best matching
14553 position for TO_CHARPOS while scanning the line, and restore it on
14554 exit if none of the characters scanned was an exact match.
14555 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14556 when exact match is impossible due to invisible text, and the
14557 lines are truncated.
14559 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14561 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14564 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14566 Fix a significant slow-down of cursor motion with C-n, C-p,
14567 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14568 auto-repeat under bidi redisplay in fontified buffers.
14569 * xdisp.c (compute_stop_pos_backwards): New function.
14570 (next_element_from_buffer): Call compute_stop_pos_backwards to
14571 find a suitable prev_stop when we find ourselves before
14573 (reseat): Don't look for prev_stop, as that could mean a very long
14575 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14576 <cached_disp_overlay_modiff>: Cache for last found display string
14578 (compute_display_string_pos): Return the cached position if asked
14579 about the same buffer in the same area of character positions, and
14580 the buffer wasn't changed since the time the display string
14581 position was cached.
14583 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14585 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14586 is an integer, which is important for empty lines. (Bug#9149)
14588 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14590 * frame.c (Fmodify_frame_parameters): In tty case, update the
14591 default face if necessary (Bug#4238).
14593 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14595 * editfns.c (Fstring_to_char): No need to explain what a character
14596 is in the docstring (Bug#6576).
14598 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14600 * xml.c (parse_region): Make sure we always return a tree.
14602 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14604 * xml.c (parse_region): If a document contains only comments,
14607 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14609 * xml.c (make_dom): Return comments, too.
14611 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14614 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14615 and the surrounding thread.
14616 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14617 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14618 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14620 * s/openbsd.h (BROKEN_SIGIO): Define.
14621 * unexelf.c (unexec) [__OpenBSD__]:
14622 Don't update the .mdebug section of the Alpha COFF symbol table.
14624 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14626 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14629 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14631 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14632 This fixes some race conditions on the permissions of any newly
14635 * alloc.c (valid_pointer_p): Use pipe, not open.
14636 This fixes some permissions issues when debugging.
14638 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14639 If fchown fails to set both uid and gid, try to set just gid,
14640 as that is sometimes allowed. Adjust the file's mode to eliminate
14641 setuid or setgid bits that are inappropriate if fchown fails.
14643 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14645 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14646 to compare Lisp_Objects.
14647 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14648 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14649 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14651 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14653 * lread.c (read_integer): Unread even EOF character.
14654 (read1): Likewise. Properly record start position of symbol.
14656 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14657 symbol character follows.
14659 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14661 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14662 This works around a problem with the previous change to Fcopy_file.
14663 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14664 and without this change, GCC might complain about discarding
14665 fchown's return value.
14667 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14669 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14671 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14673 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14675 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14677 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14678 it's used from the C level.
14680 * process.c: Use the same condition for POLL_FOR_INPUT in both
14681 keyboard.c and process.c (bug#1858).
14683 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14685 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14686 (Fgnutls_boot): Use it.
14688 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14690 * doc.c (Fsubstitute_command_keys): Revert last change.
14692 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14694 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14695 quotes the next character, and doesn't affect other longer
14696 sequences (bug#8935).
14698 * lread.c (syms_of_lread): Clarify that is isn't only
14699 `eval-buffer' and `eval-defun' that's affected by
14700 `lexical-binding' (bug#8460).
14702 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14704 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14705 bidi redisplay when a line includes both an image and is truncated.
14707 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14709 Fix minor problems found by static checking.
14710 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14711 (elsz): Now a signed constant, not a size_t var. We prefer signed
14712 types to unsigned, to avoid integer comparison confusion. Without
14713 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14714 "cannot optimize loop, the loop counter may overflow", a symptom
14716 * indent.c (Fvertical_motion): Mark locals as initialized.
14717 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14719 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14721 * search.c (Fre_search_backward): Mention `case-fold-search' in
14722 all the re_search_* functions (bug#8138).
14724 * keyboard.c (Fopen_dribble_file): Document when the file is
14727 2011-07-14 Eli Zaretskii <eliz@gnu.org>
14729 * bidi.c (bidi_dump_cached_states): Fix format of displaying
14732 Support bidi reordering of display and overlay strings.
14733 * xdisp.c (compute_display_string_pos)
14734 (compute_display_string_end): Accept additional argument STRING.
14735 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
14736 (reseat_to_string): Initialize bidi_it->string.s and
14737 bidi_it->string.schars.
14738 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
14739 NULL (avoids a crash in bidi_paragraph_init).
14740 Initialize itb.string.lstring.
14741 (init_iterator): Call bidi_init_it only of a valid
14742 buffer position was specified. Initialize paragraph_embedding to
14744 (reseat_to_string): Initialize the bidi iterator.
14745 (display_string): If we need to ignore text properties of
14746 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14747 original value of -1 will not work with bidi.)
14748 (compute_display_string_pos): First arg is now struct
14749 `text_pos *'; all callers changed. Support display properties on

15239 * alloc.c (mark_buffer):
15240 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
15241 (clone_per_buffer_values): Don't assume that

15243 This isn't true in general, and it's particularly not true
15244 if Emacs is configured with --with-wide-int.
15245 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15246 New macros, used in the buffer.c change.

15282 Random fixes. E.g., (random) never returned negative values.
15283 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15284 subseconds part to the entropy, as that's a bit more random.
15285 Prefer signed to unsigned, since the signedness doesn't matter and
15286 in general we prefer signed. When given a limit, use a
15287 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15288 latter isn't right if USE_2_TAGS_FOR_INTS.
15289 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15290 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15294 * textprop.c (text_property_stickiness):
15295 Obey Vtext_property_default_nonsticky.

15302 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15303 This is more efficient than Ffile_directory_p and avoids a minor race.
15305 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15307 * buffer.c (Foverlay_put): Say what the return value is
15310 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15311 is a directory before asking whether to use the file name
15313 (barf_or_query_if_file_exists): Make the "File is a directory"
15314 error be more correct.
15316 * fns.c (Frequire): Remove the mention of the .gz files, since
15317 that's installation-specific, but keep the mention of
15318 `get-load-suffixes'.

15328 (syms_of_gnutls): Remove duplicate DEFSYM for
15329 Qgnutls_bootprop_verify_hostname_error, an error for
15330 Qgnutls_bootprop_verify_error (which is no longer used).
15332 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15333 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15334 Also (re)move comments that are misplaced or no longer relevant.
15336 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15338 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15397 (syms_of_keymap): Defsubr make-composed-keymap.
15398 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

15435 * eval.c (struct backtrace): Simplify and port the data structure.
15436 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15437 signed bit field, as this assumption is not portable and it makes
15438 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15439 "char debug_on_exit : 1" as this is not portable either; instead,
15440 use the portable "unsigned int debug_on_exit : 1". Remove unused
15441 member evalargs. Remove obsolete comments about cc bombing out.
15443 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
15445 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

15628 (read_integer): Radix is now EMACS_INT, not int,
15629 to improve quality of diagnostics for out-of-range radices.
15630 Calculate buffer size correctly for out-of-range radices.
15631 (read1): Check for integer overflow in radices, and in
15632 read-circle numbers.
15633 (read_escape): Avoid int overflow.
15634 (Fload, openp, read_buffer_size, read1)
15635 (substitute_object_recurse, read_vector, read_list, map_obarray):
15636 Use ptrdiff_t, not int, for sizes.
15637 (read1): Use EMACS_INT, not int, for sizes.
15638 Check for size overflow.
15640 * image.c (cache_image): Check for size arithmetic overflow.
15642 * lread.c: Integer overflow issues.
15643 (saved_doc_string_size, saved_doc_string_length)

15645 Now ptrdiff_t, not int.
15646 (read1): Don't assume doc string length fits in int. Check for
15647 out-of-range doc string lengths.
15648 (read_list): Don't assume file position fits in int.
15649 (read_escape): Check for hex character overflow.
15651 2011-06-22 Leo Liu <sdl.web@gmail.com>
15653 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
15654 Move to minibuffer.el.
15656 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15658 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15659 The following patches are for when GLYPH_DEBUG && !XASSERT.
15660 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15661 * dispnew.c (flush_stdout):
15662 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15663 Mark as externally visible.
15664 * dispnew.c (check_window_matrix_pointers): Now static.
15665 * dispnew.c (window_to_frame_vpos):
15666 * xfns.c (unwind_create_frame):
15667 * xterm.c (x_check_font): Remove unused local.
15668 * scroll.c (CHECK_BOUNDS):
15669 * xfaces.c (cache_fache): Rename local to avoid shadowing.
15670 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
15671 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
15672 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
15673 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
15675 (debug_method_add): Use va_list and vsprintf rather than relying
15676 on undefined behavior with wrong number of arguments.
15677 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15678 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15679 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15680 since we're not interested in debugging glyphs with old libraries.
15681 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15682 GCC 4.6.0's static checking.
15684 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15686 Integer overflow and signedness fixes (Bug#8873).

15695 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
15696 (x_create_bitmap_from_xpm_data):
15697 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
15698 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
15700 * xfaces.c (load_pixmap):
15701 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
15702 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
15703 (.bitmaps_last, struct x_output.icon_bitmap):
15704 Use ptrdiff_t, not int, for bitmap indexes.
15705 (x_allocate_bitmap_record): Check for size overflow.
15706 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
15708 Use ptrdiff_t, not int, for overlay counts.
15709 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
15710 * editfns.c (overlays_around, get_pos_property):
15711 * textprop.c (get_char_property_and_overlay):
15712 * xdisp.c (next_overlay_change, note_mouse_highlight):
15713 * xfaces.c (face_at_buffer_position):
15714 * buffer.c (OVERLAY_COUNT_MAX): New macro.
15715 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
15716 (Fnext_overlay_change, Fprevious_overlay_change)
15717 (mouse_face_overlay_overlaps, Foverlays_in):
15718 Use ptrdiff_t, not int, for sizes.
15719 (overlays_at, overlays_in): Check for size-calculation overflow.
15721 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
15723 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15724 (x_session_initialize): Do not assume string length fits in int.
15726 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15727 This is unlikely, but can occur if DPI is outlandish.
15729 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
15730 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
15732 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
15733 * xrdb.c (magic_file_p, search_magic_path):
15734 Omit last arg SUFFIX; it was always 0. All callers changed.
15735 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
15737 * xfont.c (xfont_match): Avoid need for strlen.
15739 * xfns.c: Don't assume strlen fits in int.
15740 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
15742 * xdisp.c (message_log_check_duplicate): Return intmax_t,
15743 not unsigned long, as we prefer signed integers. All callers changed.
15744 Detect integer overflow in repeat count.
15745 (message_dolog): Don't assume print length fits in 39 bytes.
15746 (display_mode_element): Don't assume strlen fits in int.
15748 * termcap.c: Don't assume sizes fit in int and never overflow.
15749 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
15750 (gobble_line): Check for size-calculation overflow.
15752 * minibuf.c (Fread_buffer):
15753 * lread.c (intern, intern_c_string):
15754 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
15755 Don't assume string length fits in int.
15757 * keyboard.c (parse_tool_bar_item):
15758 * gtkutil.c (style_changed_cb): Avoid need for strlen.
15760 * font.c: Don't assume string length fits in int.
15761 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
15762 Use ptrdiff_t, not int.
15763 (font_intern_prop): Don't assume string length fits in int.
15764 Don't assume integer property fits in fixnum.
15765 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
15767 * filelock.c: Fix some buffer overrun and integer overflow issues.
15768 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
15769 Reformulate so as not to need the command string.
15770 Invoke gzip -cd rather than gunzip, as it's more portable.
15771 (lock_info_type, lock_file_1, lock_file):
15772 Don't assume pid_t and time_t fit in unsigned long.
15773 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15774 (current_lock_owner): Prefer signed type for sizes.
15775 Use memcpy, not strncpy, where memcpy is what is really wanted.
15776 Don't assume (via atoi) that time_t and pid_t fit in int.
15777 Check for time_t and/or pid_t out of range, e.g., via a network share.
15778 Don't alloca where an auto var works fine.
15780 * fileio.c: Fix some integer overflow issues.
15781 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15782 Don't assume string length fits in int.
15783 (directory_file_name): Don't assume string length fits in long.
15784 (make_temp_name): Don't assume pid fits in int, or that its print
15785 length is less than 20.
15787 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15789 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15791 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15793 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15794 We prefer signed integers, even for size calculations.
15796 * emacs.c: Don't assume string length fits in 'int'.
15797 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15798 (main): Don't invoke strlen when not needed.
15800 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15801 (XD_DEBUG_MESSAGE): Don't waste a byte.
15803 * callproc.c (getenv_internal_1, getenv_internal)
15804 (Fgetenv_internal):
15805 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15807 * lread.c (invalid_syntax): Omit length argument.
15808 All uses changed. This doesn't fix a bug, but it simplifies the
15809 code away from its former Hollerith-constant appearance, and it's
15810 one less 'int' to worry about when looking at integer-overflow issues.
15811 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15813 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15814 This didn't break anything, but it didn't help either.
15815 It's confusing to put a bogus integer in a place where the actual
15816 value does not matter.
15817 (LIST_END_P): Remove unused macro and its bogus comment.
15818 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15820 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15821 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15823 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15824 We prefer signed types, and the value cannot exceed the EMACS_INT
15825 range anyway (because otherwise the length would not be representable).
15826 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15827 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15828 This avoids a GCC warning when WIDE_EMACS_INT.
15830 * indent.c (sane_tab_width): New function.
15831 (current_column, scan_for_column, Findent_to, position_indentation)
15832 (compute_motion): Use it. This is just for clarity.
15833 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15835 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15837 * lisp.h (lint_assume): New macro.
15838 * composite.c (composition_gstring_put_cache):
15839 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15841 * editfns.c, insdel.c:
15842 Omit unnecessary forward decls, to simplify future changes.
15844 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15846 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15848 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15849 Use much-faster test for byte-length change.
15850 Don't assume string byte-length fits in 'int'.
15851 Check that character arg fits in 'int'.
15852 (mapcar1): Declare byte as byte, for clarity.
15854 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15856 * fns.c (concat): Catch string overflow earlier.
15857 Do not rely on integer wraparound.
15859 * dispextern.h (struct it.overlay_strings_charpos)
15860 (struct it.selective): Now EMACS_INT, not int.
15861 * xdisp.c (forward_to_next_line_start)
15862 (back_to_previous_visible_line_start)
15863 (reseat_at_next_visible_line_start, next_element_from_buffer):
15864 Don't arbitrarily truncate the value of 'selective' to int.
15866 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15868 * composite.c: Don't truncate sizes to 'int'.
15869 (composition_gstring_p, composition_reseat_it)
15870 (composition_adjust_point): Use EMACS_INT, not int.
15871 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15872 not EMACS_UINT, for indexes.
15874 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15876 * buffer.c: Include <verify.h>.
15877 (struct sortvec.priority, struct sortstr.priority):
15878 Now EMACS_INT, not int.
15879 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15880 (struct sortstr.size, record_overlay_string)
15881 (struct sortstrlist.size, struct sortlist.used):
15882 Don't truncate size to int.
15883 (record_overlay_string): Check for size-calculation overflow.
15884 (init_buffer_once): Check at compile-time, not run-time.
15886 2011-06-22 Jim Meyering <meyering@redhat.com>
15888 Don't leak an XBM-image-sized buffer
15889 * image.c (xbm_load): Free the image buffer after using it.
15891 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15894 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15895 that Sun C diagnosed.
15896 * fns.c (secure_hash): Fix pointer signedness issue.
15897 * intervals.c (static_offset_intervals): New function.
15898 (offset_intervals): Use it.
15900 2011-06-21 Leo Liu <sdl.web@gmail.com>
15903 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15906 * fns.c (secure_hash): Rename from crypto_hash_function and change
15907 the first arg to accept symbols.
15908 (Fsecure_hash): New primitive.
15909 (syms_of_fns): New symbols.
15911 2011-06-20 Deniz Dogan <deniz@dogan.se>
15913 * process.c (Fset_process_buffer): Clarify return value in
15916 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15918 * dispnew.c (add_window_display_history): Use BVAR.
15920 * xdisp.c (debug_method_add): Use BVAR.
15921 (check_window_end, dump_glyph_matrix, dump_glyph)
15922 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15924 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15927 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15928 check till after the cache is created in init_frame_faces.
15930 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15932 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15934 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15936 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15937 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15938 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15940 Improve buffer-overflow checking (Bug#8873).
15941 * fileio.c (Finsert_file_contents):
15942 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15943 Remove the old (too-loose) buffer overflow checks.
15944 They weren't needed, since make_gap checks for buffer overflow.
15945 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15946 The old code merely checked for Emacs fixnum overflow, and relied
15947 on undefined (wraparound) behavior. The new code avoids undefined
15948 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15950 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15951 Tune. Don't use wider integers than needed. Don't use alloca.
15952 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15954 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15956 * insdel.c, lisp.h (buffer_overflow): New function.
15957 (insert_from_buffer_1, replace_range, replace_range_2):
15958 * insdel.c (make_gap_larger):
15959 * editfns.c (Finsert_char):
15960 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15962 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15964 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15966 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15968 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15969 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15971 * fileio.c: Don't assume EMACS_INT fits in off_t.
15972 (emacs_lseek): New static function.
15973 (Finsert_file_contents, Fwrite_region): Use it.
15974 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15976 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15978 * fns.c: Don't overflow int when computing a list length.
15979 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15980 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15981 truncation on 64-bit hosts. Check for QUIT every
15982 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15983 faster and is responsive enough.
15984 (Flength): Report an error instead of overflowing an integer.
15985 (Fsafe_length): Return a float if the value is not representable
15986 as a fixnum. This shouldn't happen except in contrived situations.
15987 (Fnthcdr, Fsort): Don't assume list length fits in int.
15988 (Fcopy_sequence): Don't assume vector length fits in int.
15990 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15991 (header_size, word_size): New constants.
15992 (allocate_vectorlike): Don't check size overflow here.
15993 (allocate_vector): Check it here instead, since this is the only
15994 caller of allocate_vectorlike that could cause overflow.
15995 Check that the new vector's length is representable as a fixnum.
15997 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15998 The previous code was bogus. For example, next_almost_prime (32)
15999 returned 39, which is undesirable as it is a multiple of 3; and
16000 next_almost_prime (24) returned 25, which is a multiple of 5 so
16001 why was the code bothering to check for multiples of 7?
16003 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16005 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16007 Variadic C functions now count arguments with ptrdiff_t.
16008 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16009 Back then I didn't know that the Emacs coding style prefers signed int.
16010 Also, in the meantime I found a few more instances where arguments
16011 were being counted with int, which may truncate counts on 64-bit
16012 machines, or EMACS_INT, which may be unnecessarily wide.
16013 * lisp.h (struct Lisp_Subr.function.aMANY)
16014 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16015 Arg counts are now ptrdiff_t, not size_t.
16016 All variadic functions and their callers changed accordingly.
16017 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16018 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16019 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16020 * callint.c (Fcall_interactively): Check arg count for overflow,
16021 to avoid potential buffer overrun. Use signed char, not 'int',
16022 for 'varies' array, so that we needn't bother to check its size
16023 calculation for overflow.
16024 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16025 * eval.c (apply_lambda):
16026 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16027 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16028 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16030 * callint.c (Fcall_interactively): Don't use index var as event count.
16032 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16033 * mem-limits.h (SIZE): Remove; no longer used.
16035 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16037 Remove unnecessary casts.
16038 * xterm.c (x_term_init):
16039 * xfns.c (x_set_border_pixel):
16040 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16041 These aren't needed now that we assume ANSI C.
16043 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16044 It's more likely to cause problems (due to unsigned overflow)
16047 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16049 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16051 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16053 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16055 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16057 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16059 GLYPH_CODE_FACE returns EMACS_INT, not int.
16060 * dispextern.h (merge_faces):
16061 * xfaces.c (merge_faces):
16062 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16063 Don't assume EMACS_INT fits in int.
16065 * character.h (CHAR_VALID_P): Remove unused parameter.
16066 * fontset.c, lisp.h, xdisp.c: All uses changed.
16068 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16070 * fns.c (concat): Minor tuning based on overflow analysis.
16071 This doesn't fix any bugs. Use int to hold character, instead
16072 of constantly refetching from Emacs object. Use XFASTINT, not
16073 XINT, for value known to be a character. Don't bother comparing
16074 a single byte to 0400, as it's always less.
16076 * floatfns.c (Fexpt):
16077 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16079 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16082 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16084 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16085 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16086 incorrectly succeed when S was a string, because 4294967386 was
16087 truncated before it was used.
16089 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16090 Otherwise, an out-of-range integer could cause undefined behavior
16093 * composite.c: Use int, not EMACS_INT, for characters.
16094 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16095 EMACS_INT, for values that are known to be in character range.
16096 This doesn't fix any bugs but is the usual style inside Emacs and
16097 may generate better code on 32-bit machines.
16099 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16100 This is for reasons similar to the recent CHAR_STRING fix.
16101 * charset.c (Fencode_char): Check that character arg is actually
16102 a character. Pass an int to ENCODE_CHAR.
16103 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16104 wider than 'int', as a compile-time check to prevent future regressions
16107 * character.c (char_string): Remove unnecessary casts.
16109 Make sure a 64-bit char is never passed to CHAR_STRING.
16110 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16111 by silently ignoring the top 32 bits, allowing some values
16112 that were far too large to be valid characters.
16113 * character.h: Include <verify.h>.
16114 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16115 arguments are no wider than unsigned, as a compile-time check
16116 to prevent future regressions in this area.
16118 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16119 (Fsubst_char_in_region):
16121 * xdisp.c (decode_mode_spec_coding):
16122 Adjust to CHAR_STRING's new requirement.
16123 * editfns.c (Finsert_char, Fsubst_char_in_region):
16124 * fns.c (concat): Check that character args are actually
16125 characters. Without this test, these functions did the wrong
16126 thing with wildly out-of-range values on 64-bit hosts.
16128 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16129 These casts should not be needed on 32-bit hosts, either.
16130 * keyboard.c (read_char):
16131 * lread.c (Fload): Remove casts to unsigned.
16133 * lisp.h (UNSIGNED_CMP): New macro.
16134 This fixes comparison bugs on 64-bit hosts.
16135 (ASCII_CHAR_P): Use it.
16136 * casefiddle.c (casify_object):
16137 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16138 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16139 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16140 * dispextern.h (FACE_FROM_ID):
16141 * keyboard.c (read_char): Use UNSIGNED_CMP.
16143 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16144 not to EMACS_INT, to avoid GCC warning.
16146 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16148 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16149 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16150 isn't needed on 32-bit machines.
16152 * buffer.c (Fgenerate_new_buffer_name):
16153 Use EMACS_INT for count, not int.
16154 (advance_to_char_boundary): Return EMACS_INT, not int.
16156 * data.c (Qcompiled_function): Now static.
16158 * window.c (window_body_lines): Now static.
16160 * image.c (gif_load): Rename local to avoid shadowing.
16162 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16163 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16164 * alloc.c (make_save_value): Integer argument is now of type
16165 ptrdiff_t, not int.
16166 (mark_object): Use ptrdiff_t, not int.
16167 * lisp.h (pD): New macro.
16168 * print.c (print_object): Use it.
16170 * alloc.c: Use EMACS_INT, not int, to count objects.
16171 (total_conses, total_markers, total_symbols, total_vector_size)
16172 (total_free_conses, total_free_markers, total_free_symbols)
16173 (total_free_floats, total_floats, total_free_intervals)
16174 (total_intervals, total_strings, total_free_strings):
16175 Now EMACS_INT, not int. All uses changed.
16176 (Fgarbage_collect): Compute overall total using a double, so that
16177 integer overflow is less likely to be a problem. Check for overflow
16178 when converting back to an integer.
16179 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16180 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16181 These were 'int' variables that could overflow on 64-bit hosts;
16182 they were never used, so remove them instead of repairing them.
16183 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16184 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16185 Previously, this ceilinged at INT_MAX, but that doesn't work on
16187 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16189 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16190 (allocate_vectorlike): Check for ptrdiff_t overflow.
16191 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16192 when a (possibly-narrower) signed value would do just as well.
16193 We prefer using signed arithmetic, to avoid comparison confusion.
16195 * alloc.c: Catch some string size overflows that we were missing.
16196 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16197 for convenience in STRING_BYTES_MAX.
16198 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16199 The definition here is exact; the one in lisp.h was approximate.
16200 (allocate_string_data): Check for string overflow. This catches
16201 some instances we weren't catching before. Also, it catches
16202 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16203 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16204 and ptrdiff_t and EMACS_INT are both 64 bits.
16206 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16207 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16208 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16210 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16212 * alloc.c (Fmake_string): Check for out-of-range init.
16214 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16216 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16218 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16220 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16221 xg_get_default_scrollbar_width.
16223 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16224 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16225 (style_changed_cb): Call update_theme_scrollbar_width and call
16226 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16227 all frames (Bug#8505).
16228 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16229 Call gtk_window_set_resizable if HAVE_GTK3.
16230 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16231 and height if HAVE_GTK3 (Bug#8505).
16232 (scroll_bar_width_for_theme): New variable.
16233 (update_theme_scrollbar_width): New function.
16234 (xg_get_default_scrollbar_width): Move code to
16235 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16236 (xg_initialize): Call update_theme_scrollbar_width.
16238 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16240 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16242 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16244 * frame.c (make_frame): Call other_buffer_safely instead of
16247 * window.c (temp_output_buffer_show): Call display_buffer with
16248 second argument Vtemp_buffer_show_specifiers and reset latter
16249 immediately after the call.
16250 (Vtemp_buffer_show_specifiers): New variable.
16251 (auto_window_vscroll_p, next_screen_context_lines)
16252 (Vscroll_preserve_screen_position): Remove leading asterisks from

16803 (display_prop_intangible_p): Reimplement to call
16804 handle_display_spec instead of single_display_spec_intangible_p.

16816 value of a `display' property is a "replacing spec".
16817 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16818 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

16846 All callers changed. (Bug#8762)
16848 * gnutls.c: Use Emacs's memory allocators.
16849 Without this change, the gnutls library would invoke malloc etc.
16850 directly, which causes problems on non-SYNC_INPUT hosts, and which
16851 runs afoul of improving memory_full behavior. (Bug#8761)
16852 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16853 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16854 xfree instead of the default malloc, realloc, free.
16855 (Fgnutls_boot): No need to check for memory allocation failure,
16856 since xmalloc does that for us.

16880 * alloc.c (allocate_vectorlike):
16881 Check for overflow in vector size calculations.
16882 * ccl.c (ccl_driver):
16883 Check for overflow when converting EMACS_INT to int.

16885 need to be updated by these changes.
16886 * fns.c (make_hash_table, maybe_resize_hash_table):
16887 Check for integer overflow with large hash tables.
16888 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16889 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16890 (SXHASH_REDUCE): New macro.
16891 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16892 Use it instead of discarding useful hash info with large hash values.
16893 (sxhash_float): New function.
16894 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16895 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16896 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16897 Rewrite to use FIXNUM_BITS, as this simplifies things.
16898 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16899 Adjust signatures to match updated version of code.
16900 (consing_since_gc): Now EMACS_INT, since a single hash table can
16901 use more than INT_MAX bytes.

16929 only when CANNOT_DUMP is defined.
16930 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
16932 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16934 * dispnew.c (add_window_display_history): Use const for the string
16935 pointer. Remove declaration, not needed.
16937 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16939 Use 'inline', not 'INLINE'.
16940 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
16941 * alloc.c, fontset.c (INLINE): Remove.
16942 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
16943 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
16944 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16945 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16946 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16948 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16950 Make it possible to run ./temacs.
16952 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16953 syms_of_callproc does the same thing. Remove test for
16954 "initialized", do it in the caller.
16955 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16957 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16959 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16960 (read_minibuf): Use get_minibuffer.
16961 (syms_of_minibuf): Use DEFSYM.
16962 (Qmetadata): New var.
16963 * data.c (Qbuffer): Don't make it static.
16964 (syms_of_data): Use DEFSYM.
16966 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16968 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16969 (CCL_CODE_MIN): New macro.
16971 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16973 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16975 * eval.c (Qdebug): Now static.
16976 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16977 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16978 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16980 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16982 * image.c: Various fixes to ImageMagick code comments.
16983 (Fimagemagick_types): Doc fix.
16985 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16987 Minor fixes prompted by GCC 4.6.0 warnings.
16989 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16991 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16992 (x_clipboard_manager_save_all): Move extern decl to ...
16993 * xterm.h: ... here, so that it can be checked for consistency.
16995 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16997 * xselect.c (x_clipboard_manager_save_frame)
16998 (x_clipboard_manager_save_all): New functions.
16999 (Fx_clipboard_manager_save): Lisp function deleted.
17001 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17002 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17004 * xterm.h: Update prototype.
17006 2011-05-28 William Xu <william.xwl@gmail.com>
17008 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17009 exiting (Bug#8239).
17011 2011-05-28 Jim Meyering <meyering@redhat.com>
17013 Avoid a sign-extension bug in crypto_hash_function.
17014 * fns.c (to_uchar): Define.
17015 (crypto_hash_function): Use it to convert some newly-signed
17016 variables to unsigned, to avoid sign-extension bugs. For example,
17017 without this change, (md5 "truc") would evaluate to
17018 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17019 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17020 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17022 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17024 Integer overflow fixes.
17026 * dbusbind.c: Serial number integer overflow fixes.
17027 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17028 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17029 to hold a serial number that is too large for a fixnum.
17030 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17031 Check for serial numbers out of range. Decode any serial number
17032 that was so large that it became a float. (Bug#8722)
17034 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17035 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17036 Use XFASTINT rather than XUINT when numbers are nonnegative.
17037 (xd_append_arg, Fdbus_method_return_internal):
17038 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17039 arguments, check that Lisp number is nonnegative, rather than
17040 silently wrapping negative numbers around. (Bug#8722)
17041 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17044 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17046 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17048 ccl: Add integer overflow checks.
17049 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17050 (IN_INT_RANGE): New macros.
17051 (ccl_driver): Use them to check for integer overflow when
17052 decoding a CCL program. Many of the new checks are whether XINT (x)
17053 fits in int; it doesn't always, on 64-bit hosts. The new version
17054 doesn't catch all possible integer overflows, but it's an
17055 improvement. (Bug#8719)
17057 * alloc.c (make_event_array): Use XINT, not XUINT.
17058 There's no need for unsigned here.
17060 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17061 This follows up to the 2011-05-06 change that substituted uintptr_t
17062 for EMACS_INT. This case wasn't caught back then.
17064 Rework Fformat to avoid integer overflow issues.
17065 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17066 now (part of C89). Include <verify.h>.
17067 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17068 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17069 (Fformat): Avoid the prepass trying to compute sizes; it was only
17070 approximate and thus did not catch overflow reliably. Instead, walk
17071 through the format just once, formatting and computing sizes as we go,
17072 checking for integer overflow at every step, and allocating a larger
17073 buffer as needed. Keep track separately whether the format is
17074 multibyte. Keep only the most-recently calculated precision, rather
17075 than them all. Record whether each argument has been converted to
17076 string. Use EMACS_INT, not int, for byte and char and arg counts.
17077 Support field widths and precisions larger than INT_MAX. Avoid
17078 sprintf's undefined behavior with conversion specifications such as %#d
17079 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17080 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17081 formatting out-of-range floating point numbers with int
17082 formats. (Bug#8668)
17084 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17086 * data.c: Avoid integer truncation in expressions involving floats.
17087 * data.c: Include <intprops.h>.
17088 (arith_driver): When there's an integer overflow in an expression
17089 involving floating point, convert the integers to floating point
17090 so that the resulting value does not suffer from catastrophic
17091 integer truncation. For example, on a 64-bit host (* 4
17092 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17093 Do not rely on undefined behavior after integer overflow.
17095 merge count_size_as_multibyte, parse_str_to_multibyte
17096 * character.c, character.h (count_size_as_multibyte):
17097 Rename from parse_str_to_multibyte; all uses changed.
17098 Check for integer overflow.
17099 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17100 since it's now a duplicate of the other. This is more of
17101 a character than a buffer op, so better that it's in character.c.
17102 * fns.c, print.c: Adjust to above changes.
17104 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17106 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17108 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17110 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17111 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17112 (x_clipboard_manager_save): Now static.
17113 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17115 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17116 (crypto_hash_function): Now static.
17117 Fix pointer signedness problems. Avoid unnecessary initializations.
17119 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17121 * termhooks.h (Vselection_alist): Make it terminal-local.
17123 * terminal.c (create_terminal): Initialize it.
17125 * xselect.c: Support for clipboard managers.
17126 (Vselection_alist): Move to termhooks.h as terminal-local var.
17127 (LOCAL_SELECTION): New macro.
17128 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17129 (symbol_to_x_atom): Remove gratuitous arg.
17130 (x_handle_selection_request, lisp_data_to_selection_data)
17131 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17132 (x_own_selection, x_get_local_selection, x_convert_selection):
17133 New arg, specifying work frame. Use terminal-local Vselection_alist.
17134 (some_frame_on_display): Delete unused function.
17135 (Fx_own_selection_internal, Fx_get_selection_internal)
17136 (Fx_disown_selection_internal, Fx_selection_owner_p)
17137 (Fx_selection_exists_p): New optional frame arg.
17138 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17139 (x_handle_selection_clear): Don't treat other terminals with the
17140 same keyboard specially. Use the terminal-local Vselection_alist.
17141 (x_clear_frame_selections): Use Frun_hook_with_args.
17143 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17145 * xterm.h: Add support for those atoms.
17147 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17149 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17150 (converted_selections, conversion_fail_tag): New global variables.
17151 (x_selection_request_lisp_error): Free the above.
17152 (x_get_local_selection): Remove unnecessary code.
17153 (x_reply_selection_request): Args changed; handle arbitrary array
17154 of converted selections stored in converted_selections.
17155 Separate the XChangeProperty and SelectionNotify steps.
17156 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17157 (x_convert_selection): New function.
17158 (x_handle_selection_event): Simplify.
17159 (x_get_foreign_selection): Don't ignore incoming requests while
17160 waiting for an answer; this will fail when we implement
17161 SAVE_TARGETS, and seems unnecessary anyway.
17162 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17163 (Vx_sent_selection_functions): Doc fix.
17165 2011-05-26 Leo Liu <sdl.web@gmail.com>
17167 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17169 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17171 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17173 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17174 for fringe update if it has periodic bitmap.
17175 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17176 and fringe_bitmap_periodic_p.
17178 * fringe.c (get_fringe_bitmap_data): New function.
17179 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17180 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17181 row. Mark glyph row for fringe update if periodicity changed.
17183 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17184 for fringe update unless it has periodic bitmap.
17186 2011-05-25 Kenichi Handa <handa@m17n.org>
17188 * xdisp.c (get_next_display_element): Set correct it->face_id for
17189 a static composition.
17191 2011-05-24 Leo Liu <sdl.web@gmail.com>
17194 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17196 * fns.c (crypto_hash_function, Fsha1): New function.
17197 (Fmd5): Use crypto_hash_function.
17198 (syms_of_fns): Add Ssha1.
17200 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17202 * gnutls.c: Remove unused macros.
17203 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17204 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17205 Remove macros that are defined and never used.
17206 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17208 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17210 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17211 (Fx_get_selection_internal): Minor cleanup.
17212 (Fx_own_selection_internal): Rename arguments for consistency with
17215 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17217 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17219 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17221 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17223 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17225 * dispnew.c (scrolling_window): Don't exclude the case that the
17226 last enabled row in the desired matrix touches the bottom boundary.
17228 2011-05-21 Glenn Morris <rgm@gnu.org>
17230 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17231 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17232 and add some more files.
17234 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17236 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17237 report_file_error introduced by the change from 2011-05-07.
17239 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17241 * systime.h (Time): Define only if emacs is defined.
17242 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17243 where the include path doesn't have X11/X.h by default. See
17244 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17246 2011-05-20 Kenichi Handa <handa@m17n.org>
17248 * composite.c (find_automatic_composition): Fix previous change.
17250 2011-05-20 Glenn Morris <rgm@gnu.org>
17252 * lisp.mk: New file, split from Makefile.in.
17253 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17254 (shortlisp): Remove.
17255 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17257 2011-05-19 Glenn Morris <rgm@gnu.org>
17259 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17260 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17261 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17262 (lisp): Set the order to that of loadup.el.
17263 (shortlisp): Make it a copy of $lisp.
17264 (SOME_MACHINE_LISP): Remove.
17265 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17266 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17268 2011-05-18 Kenichi Handa <handa@m17n.org>
17270 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17271 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17272 (find_automatic_composition): Mostly rewrite for efficiency.
17274 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17276 * makefile.w32-in: Update dependencies.
17278 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17280 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17281 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17283 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17285 Fix some integer overflow issues, such as string length overflow.
17287 * insdel.c (count_size_as_multibyte): Check for string overflow.
17289 * character.c (lisp_string_width): Check for string overflow.
17290 Use EMACS_INT, not int, for string indexes and lengths; in
17291 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17292 the resulting string length overflows an EMACS_INT; instead,
17293 report a string overflow if no precision given. When checking for
17294 precision exhaustion, use a check that cannot possibly have
17295 integer overflow. (Bug#8675)
17296 * character.h (lisp_string_width): Adjust to new signature.
17298 * alloc.c (string_overflow): New function.
17299 (Fmake_string): Use it. This doesn't change behavior, but saves
17300 a few bytes and will simplify future changes.
17301 * character.c (string_escape_byte8): Likewise.
17302 * lisp.h (string_overflow): New decl.
17304 Fixups, following up to the user-interface timestamp change.
17305 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17306 for UI timestamps, instead of unsigned long.
17307 * msdos.c (mouse_get_pos): Likewise.
17308 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17309 * w32gui.h (Time): Define by including "systime.h" rather than by
17310 declaring it ourselves. (Bug#8664)
17312 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17313 * image.c (clear_image_cache): Likewise.
17315 * term.c (term_mouse_position): Don't assume time_t wraparound.
17317 Be more systematic about user-interface timestamps.
17318 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17319 and sometimes 'EMACS_UINT', to represent these timestamps.
17320 This change causes it to use 'Time' uniformly, as that's what X uses.
17321 This makes the code easier to follow, and makes it easier to catch
17322 integer overflow bugs such as Bug#8664.
17323 * frame.c (Fmouse_position, Fmouse_pixel_position):
17324 Use Time, not unsigned long, for user-interface timestamps.
17325 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17326 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17327 * keyboard.h (last_event_timestamp): Likewise.
17328 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17329 * menu.h (xmenu_show): Likewise.
17330 * term.c (term_mouse_position): Likewise.
17331 * termhooks.h (struct input_event.timestamp): Likewise.
17332 (struct terminal.mouse_position_hook): Likewise.
17333 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17334 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17335 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17336 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17337 what it was before.
17338 * menu.h, termhooks.h: Include "systime.h", for Time.
17340 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17341 Don't assume that the difference between two unsigned long values
17342 can fit into an integer. At this point, we know button_down_time
17343 <= event->timestamp, so the difference must be nonnegative, so
17344 there's no need to cast the result if double-click-time is
17345 nonnegative, as it should be; check that it's nonnegative, just in
17346 case. This bug is triggered when events are more than 2**31 ms
17347 apart (about 25 days). (Bug#8664)
17349 * xselect.c (last_event_timestamp): Remove duplicate decl.
17350 (x_own_selection): Remove needless cast to unsigned long.
17352 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17353 that always fit in int. Use a sentinel instead of a counter, to
17354 avoid a temp and to allay GCC's concerns about possible int overflow.
17355 * frame.h (struct frame): Use int for menu_bar_items_used
17356 instead of EMACS_INT, since it always fits in int.
17358 * menu.c (grow_menu_items): Check for int overflow.
17360 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17362 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17363 Before, the code was not consistent. These values cannot exceed
17364 2**31 - 1 so there's no need to make them unsigned.
17365 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17366 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17367 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17369 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17371 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17372 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17373 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17374 presumably because the widths might not match.
17376 * window.c (size_window): Avoid needless test at loop start.
17378 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17380 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17382 2011-05-12 Drew Adams <drew.adams@oracle.com>
17384 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17386 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17388 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17389 `width' to `bar_area_x' and `bar_area_width', respectively.
17390 (x_scroll_run): Take account of fringe background extension.
17392 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17393 Rename local vars `left' and `width' to `bar_area_x' and
17394 `bar_area_width', respectively.
17395 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17396 background extension.
17398 2011-05-10 Jim Meyering <meyering@redhat.com>
17400 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17402 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17404 * image.c (Finit_image_library): Return t for built-in image types,
17405 like pbm and xbm. (Bug#8640)
17407 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17409 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17411 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17413 * w32console.c (Fset_screen_color): Doc fix.
17414 (Fget_screen_color): New function.
17415 (syms_of_ntterm): Defsubr it.
17417 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17418 unlink the temporary file if Fcall_process didn't create it in the
17420 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17421 child process will be redirected to a file specified with `:file'.
17422 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17423 cue to call_process_cleanup not to close that handle.
17425 2011-05-07 Ben Key <bkey76@gmail.com>
17427 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17428 one of two shell specific rules, either bootstrap-temacs-CMD or
17429 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17430 to the previous implementation of the bootstrap-temacs rule.
17431 The bootstrap-temacs-CMD rule is similar to the previous
17432 implementation of the bootstrap-temacs rule except that it
17433 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17436 These changes, along with some changes to nt/configure.bat,
17437 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17438 earlier fix to add support for --cflags and --ldflags options
17439 that include quotes so that it works whether make uses cmd or
17442 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17444 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17445 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17447 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17448 a string. Handle both cases.
17449 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17450 (Fdbus_register_method): Use Qinvalid_function.
17452 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17454 * makefile.w32-in: Update dependencies.
17455 (LISP_H): Add inttypes.h and stdin.h.
17456 (PROCESS_H): Add unistd.h.
17458 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17460 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17461 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17463 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17465 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17467 * term.c (vfatal): Remove stray call to va_end.
17468 It's not needed and the C Standard doesn't allow it here anyway.
17470 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17471 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17473 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17476 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17478 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17480 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17482 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17484 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17486 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17487 * charset.c (Fdefine_charset_internal): Don't initialize
17488 charset.code_space[15]. The value was garbage, on hosts with
17489 32-bit int (Bug#8600).
17491 * lread.c (read_integer): Be more consistent with string-to-number.
17492 Use string_to_number to do the actual conversion; this avoids
17493 rounding errors and fixes some other screwups. Without this fix,
17494 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17495 (digit_to_number): Move earlier, for benefit of read_integer.
17496 Return -1 if the digit is out of range for the base, -2 if it is
17497 not a digit in any supported base. (Bug#8602)
17499 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17501 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17502 to match comment at start of function. This also removes a
17503 GCC warning about overflow in a 32+64-bit port.
17505 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17507 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17508 Reported by Stefan Monnier in
17509 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17510 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17511 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17513 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17514 (EMACS_UINTPTR): Likewise, with uintptr_t.
17516 * lisp.h: Prefer 64-bit EMACS_INT if available.
17517 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17518 on 32-bit hosts that have 64-bit int, so that they can access
17520 However, temporarily disable this change unless the temporary
17521 symbol WIDE_EMACS_INT is defined.
17523 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17525 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17526 This removes an assumption that EMACS_INT and long are the same
17527 width as pointers. The assumption is true for Emacs porting targets
17528 now, but we want to make other targets possible.
17529 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17530 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17531 In the rest of the code, change types of integers that hold casted
17532 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17533 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17534 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17535 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17536 No need to cast type when ORing.
17537 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17538 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17539 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17540 assume EMACS_INT is the same width as char *.
17541 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17542 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17543 Remove no-longer-needed casts.
17544 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17545 (xg_tool_bar_help_callback, xg_make_tool_item):
17546 Use EMACS_INTPTR to hold an integer
17547 that will be cast to void *; this can avoid a GCC warning
17548 if EMACS_INT is not the same width as void *.
17549 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17550 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17551 (current_message_1, set_message_1):
17552 Use a local to convert to proper width without a cast.
17553 * xmenu.c (dialog_selection_callback): Likewise.
17555 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17556 Also, don't assume VALBITS / RAND_BITS is less than 5,
17557 and don't rely on undefined behavior when shifting a 1 left into
17559 * lisp.h (get_random): Change signature to match.
17561 * lread.c (hash_string): Use size_t, not int, for hash computation.
17562 Normally we prefer signed values; but hashing is special, because
17563 it's better to use unsigned division on hash table sizes so that
17564 the remainder is nonnegative. Also, size_t is the natural width
17565 for hashing into memory. The previous code used 'int', which doesn't
17566 retain enough info to hash well into very large tables.
17567 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17569 * dbusbind.c: Don't possibly lose pointer info when converting.
17570 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17571 Use XPNTR rather than XHASH, so that the high-order bits of
17572 the pointer aren't lost when converting through void *.
17574 * eval.c (Fautoload): Don't double-shift a pointer.
17576 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17578 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17580 * gnutls.c (DEF_GNUTLS_FN):
17581 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17583 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17585 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17588 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17590 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17591 New version that can reserve upto 2GB of heap space.
17593 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17595 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17597 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17599 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17600 `gnutls_certificate_set_x509_key_file'.
17602 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17604 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17605 Update dependencies.
17607 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17609 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17610 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17611 Remove unused parameter `fildes'.
17612 * process.c (read_process_output, send_process): Don't pass it.
17614 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17616 Fix previous change: the library cache is defined in w32.c.
17617 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17618 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17620 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17622 Implement dynamic loading of GnuTLS on Windows.
17624 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17625 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17626 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17629 * gnutls.c (Qgnutls_dll): Define.
17630 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17631 (gnutls_*): Declare function pointers.
17632 (init_gnutls_functions): New function to initialize function pointers.

17635 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17636 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17637 (emacs_gnutls_write, emacs_gnutls_read)
17638 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17639 (Fgnutls_available_p): New function.
17640 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
17641 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
17642 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
17644 * image.c: Include w32.h.
17645 (Vimage_type_cache): Delete.
17646 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
17647 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
17648 (w32_delayed_load): Move to w32.c.
17650 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17652 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17653 (w32_delayed_load): Move from image.c. When loading a library, record
17654 its filename in the :loaded-from property of the library id.
17655 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17656 Initialize and staticpro them.
17657 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17659 * process.c: Include lisp.h before w32.h, not after.
17660 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17661 instead of gnutls_record_check_pending.
17663 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17665 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17667 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17668 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17671 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17673 * xterm.c (x_set_frame_alpha): Do not set property on anything
17674 else than FRAME_X_OUTER_WINDOW (Bug#8608).

17694 * callproc.c: Indentation fixup.
17696 * sysdep.c (wait_for_termination_1): Make static.
17697 (wait_for_termination, interruptible_wait_for_termination):
17698 Move after wait_for_termination_1.
17700 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
17702 * sysdep.c (interruptible_wait_for_termination): New function
17703 which is like wait_for_termination, but allows keyboard
17706 * callproc.c (Fcall_process): Add (:file "file") as an option for
17708 (Fcall_process_region): Ditto.
17710 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17712 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17713 rather than `XVECTOR (FOO)->size'.
17715 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17716 inttypes.h, as a gnulib replacement is used if it not available in
17719 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17721 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17722 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17723 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17725 * coding.c (coding_alloc_by_realloc): Error out if destination
17726 will grow beyond MOST_POSITIVE_FIXNUM.
17727 (decode_coding_emacs_mule): Abort if there isn't enough place in

17738 %llo or %llx format is passed. (Bug#8545)
17740 * window.c (window_scroll_line_based): Use a marker instead of
17741 simple variables to record original value of point. (Bug#7952)
17743 * doprnt.c (doprnt): Fix the case where a multibyte sequence
17744 produced by %s or %c overflows available buffer space. (Bug#8545)
17746 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17748 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
17749 (SIZE_MAX): Move defn after all includes, as they might #define it.
17751 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17753 * w32.c (init_environment): Warn about defaulting HOME to C:\.

17773 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17775 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
17777 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
17779 * makefile.w32-in: Update dependencies.
17781 2011-04-27 Eli Zaretskii <eliz@gnu.org>
17783 Improve `doprnt' and its usage. (Bug#8545)
17784 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17785 `format_end'. Remove support for %l as a conversion specifier.
17786 Don't use xrealloc. Improve diagnostics when the %l size modifier
17787 is used. Update the commentary.
17789 * eval.c (verror): Simplify calculation of size_t.
17791 * coding.c (Ffind_operation_coding_system): Fix diagnostic error

17796 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17799 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17801 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17802 This makes this file independent of the recent pseudovector change.
17804 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17806 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17808 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17809 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17810 Remove unused local.
17811 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17813 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17814 GCC 4.6.0 optimizes based on type-based alias analysis.
17815 For example, if b is of type struct buffer * and v of type struct
17816 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17817 != &v->size, and therefore "v->size = 1; b->size = 2; return
17818 v->size;" must therefore return 1. This assumption is incorrect
17819 for Emacs, since it type-puns struct Lisp_Vector * with many other
17820 types. To fix this problem, this patch adds a new type struct
17821 vectorlike_header that documents the constraints on layout of vectors
17822 and pseudovectors, and helps optimizing compilers not get fooled
17823 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17824 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17825 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17827 (XSETPVECTYPE): Rewrite in terms of new macro.
17828 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17829 This is a bit clearer, and further avoids the possibility of
17830 undesirable aliasing.
17831 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17832 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17833 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17834 since Lisp_Subr is a special case (no "next" field).
17835 (ASIZE): Now uses header.size rather than size.
17836 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17837 to avoid the hassle of writing XVECTOR (foo)->header.size.
17838 (struct vectorlike_header): New type.
17839 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17840 object, to help avoid aliasing.
17841 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17842 (SUBRP): Likewise, since Lisp_Subr is a special case.
17843 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17844 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17845 (struct Lisp_Hash_Table): Combine first two members into a single
17846 struct vectorlike_header member. All uses of "size" and "next" members
17847 changed to be "header.size" and "header.next".
17848 * buffer.h (struct buffer): Likewise.
17849 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17850 * frame.h (struct frame): Likewise.
17851 * process.h (struct Lisp_Process): Likewise.
17852 * termhooks.h (struct terminal): Likewise.
17853 * window.c (struct save_window_data, struct saved_window): Likewise.
17854 * window.h (struct window): Likewise.
17855 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17856 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17857 * buffer.c (init_buffer_once): Likewise.
17858 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17860 * process.c (Fformat_network_address): Use local var for size,
17863 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17865 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17866 * data.c (atof): Remove decl; no longer used or needed.
17867 (digit_to_number): Move to lread.c.
17868 (Fstring_to_number): Use new string_to_number function, to be
17869 consistent with how the Lisp reader treats infinities and NaNs.
17870 Do not assume that floating-point numbers represent EMACS_INT
17871 without losing information; this is not true on most 64-bit hosts.
17872 Avoid double-rounding errors, by insisting on integers when
17873 parsing non-base-10 numbers, as the documentation specifies.
17874 * lisp.h (string_to_number): New decl, replacing ...
17875 (isfloat_string): Remove.
17876 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17877 (read1): Do not accept +. and -. as integers; this
17878 appears to have been a coding error. Similarly, do not accept
17879 strings like +-1e0 as floating point numbers. Do not report
17880 overflow for integer overflows unless the base is not 10 which
17881 means we have no simple and reliable way to continue.
17882 Break out the floating-point parsing into a new
17883 function string_to_number, so that Fstring_to_number parses
17884 floating point numbers consistently with the Lisp reader.
17885 (digit_to_number): Move here from data.c. Make it static inline.
17886 (E_CHAR, EXP_INT): Remove, replacing with ...
17887 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17888 (string_to_number): New function, replacing isfloat_string.
17889 This function checks for valid syntax and produces the resulting
17890 Lisp float number too. Rework it so that string-to-number
17891 no longer mishandles examples like "1.0e+". Use strtoumax,
17892 so that overflow for non-base-10 numbers is reported only when
17893 there's no portable and simple way to convert to floating point.
17895 * textprop.c (set_text_properties_1): Rewrite for clarity,
17896 and to avoid GCC warning about integer overflow.
17898 * intervals.h (struct interval): Use EMACS_INT for members
17899 where EMACS_UINT might cause problems. See
17900 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17901 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17902 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17904 (offset_intervals): Tell GCC not to worry about length overflow
17905 when negating a negative length.
17907 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17908 (overrun_check_free): Likewise.
17910 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17911 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17914 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17915 (gnutls_make_error): Rename local to avoid shadowing.
17916 (gnutls_emacs_global_deinit): ifdef out; not used.
17917 (Fgnutls_boot): Use const for pointer to readonly storage.
17918 Comment out unused local. Fix pointer signedness problems.
17920 * lread.c (openp): Don't stuff size_t into an 'int'.
17921 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17922 about possible signed overflow.
17924 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17925 (GDK_KEY_g): Don't define if already defined.
17926 (xg_prepare_tooltip): Avoid pointer signedness problem.
17927 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17929 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17930 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17932 * xfns.c (Fx_window_property): Simplify a bit,
17933 to make a bit faster and to avoid GCC 4.6.0 warning.
17934 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17936 * fns.c (internal_equal): Don't assume size_t fits in int.
17938 * alloc.c (compact_small_strings): Tighten assertion a little.
17940 Replace pEd with more-general pI, and fix some printf arg casts.
17941 * lisp.h (pI): New macro, generalizing old pEd macro to other
17942 conversion specifiers. For example, use "...%"pI"d..." rather
17943 than "...%"pEd"...".
17944 (pEd): Remove. All uses replaced with similar uses of pI.
17945 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17946 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17947 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17948 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17949 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17950 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17951 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17953 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17954 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17955 * print.c (safe_debug_print, print_object): Likewise.
17956 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17958 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17959 avoiding the 0 flag, which is not portable.
17960 * process.c (Fmake_network_process): Use pI to avoid cast.
17961 * region-cache.c (pp_cache): Likewise.
17962 * xdisp.c (decode_mode_spec): Likewise.
17963 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17964 behavior on 64-bit hosts with printf arg.
17965 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17966 (x_stop_queuing_selection_requests): Likewise.
17967 (x_get_window_property): Don't truncate byte count to an 'int'
17970 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17971 here, since it parses constructs like leading '-' and spaces,
17972 which are not wanted; and it overflows with large numbers.
17973 Instead, simply match F[0-9]+, which is what is wanted anyway.
17975 * alloc.c: Remove unportable assumptions about struct layout.
17976 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17977 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17978 (allocate_vectorlike, make_pure_vector): Use the new macros,
17979 plus offsetof, to remove unportable assumptions about struct layout.
17980 These assumptions hold on all porting targets that I know of, but
17981 they are not guaranteed, they're easy to remove, and removing them
17982 makes further changes easier.
17984 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17985 This doesn't fix a bug but makes the code clearer.
17986 (string_overrun_cookie): Now const. Use initializers that
17987 don't formally overflow signed char, to avoid warnings.
17988 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17989 can cause Emacs to crash when string overrun checking is enabled.
17990 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17991 multiple of sizeof (EMACS_INT); it need not be, if
17992 alignof(EMACS_INT) < sizeof (EMACS_INT).
17993 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17995 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
17997 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
17999 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

18002 supposed to be handshaking. (Bug#8556)
18003 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18005 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

18011 matches the current signal symbol.
18013 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18015 * alloc.c (check_sblock, check_string_bytes)
18016 (check_string_free_list): Convert to standard C.
18018 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18020 * w32.c (emacs_gnutls_push): Fix typo.
18022 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18024 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18025 "cast to pointer from integer of different size".
18027 Improve doprnt and its use in verror. (Bug#8545)
18028 * doprnt.c (doprnt): Document the set of format control sequences
18029 supported by the function. Use SAFE_ALLOCA instead of always
18032 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18033 is one byte too soon. Don't use xrealloc; instead xfree and
18036 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18038 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18041 * gnutls.c: Renamed global_initialized to
18042 gnutls_global_initialized. Added internals for the
18043 :verify-hostname-error, :verify-error, and :verify-flags
18044 parameters of `gnutls-boot' and documented those parameters in the
18045 docstring. Start callback support.
18046 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18047 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18048 on error. Return error code.
18049 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18050 (emacs_gnutls_read): Likewise.
18051 (Fgnutls_boot): Return handshake error code.
18052 (emacs_gnutls_handle_error): New function.
18053 (wsaerror_to_errno): Likewise.

18064 buffered some data internally if no FDs are set for TLS
18067 * makefile.w32-in (OBJ2): Add gnutls.$(O).

18108 changes in globals.h immediately force recompilation.
18109 (TAGS): Depend on $(CURDIR)/m/intel386.h and
18110 $(CURDIR)/s/ms-w32.h.

18115 <char-direction-table>: Deleted.
18117 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18119 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
18120 * doprnt.c: Include limits.h.
18121 (SIZE_MAX): New macro.
18122 (doprnt): Return a size_t value. 2nd arg is now size_t.
18123 Many local variables are now size_t instead of int or unsigned.
18124 Improve overflow protection. Support `l' modifier for integer
18125 conversions. Support %l conversion. Don't assume an EMACS_INT
18126 argument for integer conversions and for %c.
18128 * lisp.h (doprnt): Restore prototype.
18130 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18131 $(SRC)/character.h.
18133 * Makefile.in (base_obj): Add back doprnt.o.
18135 * deps.mk (doprnt.o): Add back prerequisites.
18136 (callint.o): Depend on character.h.
18138 * eval.c (internal_lisp_condition_case): Include the handler
18139 representation in the error message.
18140 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
18141 when breaking from the loop.
18143 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
18145 * callint.c (Fcall_interactively): When displaying error message
18146 about invalid control letter, pass the character's codepoint, not
18147 a pointer to its multibyte form. Improve display of the character
18148 in octal and display also its hex code.
18150 * character.c (char_string): Use %x to display the (unsigned)
18151 codepoint of an invalid character, to avoid displaying a bogus
18154 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18155 `error', not SYMBOL_NAME itself.
18157 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18158 character arguments to `error'.
18160 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18161 to `error' in error message about FINAL_CHAR argument. Make sure
18162 FINAL_CHAR is a character, and use %c when it is passed as
18163 argument to `error'.
18165 2011-04-23 Eli Zaretskii <eliz@gnu.org>

18227 Define only if needed.
18229 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18230 by pacifying GCC about it. Maybe it's time to retire it?
18231 * xfaces.c (USG, __TIMEVAL__): Likewise.
18233 * dispextern.h (struct redisplay_interface): Rename param
18234 to avoid shadowing.
18235 * termhooks.h (struct terminal): Likewise.
18236 * xterm.c (xembed_send_message): Likewise.
18238 * insdel.c (make_gap_smaller): Define only if
18239 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
18241 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
18244 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,

18698 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
18699 * ccl.c (Vccl_program_table): Now static.
18700 (check_ccl_update): Remove; unused.
18702 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
18703 * category.h: ... from here.
18704 * category.c (check_category_table, set_category_set): Now static.
18706 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
18707 * lisp.h: Remove these decls.
18709 * buffer.c (buffer_count): Remove unused var.
18711 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
18712 so that it's not optimized away.
18713 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
18714 * dispextern.h (bidi_dump_cached_states): Remove, since it's
18715 exported only to the debugger.
18717 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
18718 * atimer.h (run_all_atimers): Remove; not exported.
18720 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
18721 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
18722 was inaccessible from Lisp.
18723 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
18724 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
18726 alloc.c: Import and export fewer symbols, and remove unused items.
18727 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
18729 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
18730 it's not optimized away by whole-program optimization.
18731 (message_enable_multibyte, free_misc): Remove.
18732 (catchlist, handlerlist, mark_backtrace):
18733 Declare only if BYTE_MARK_STACK.
18734 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
18735 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
18736 (message_enable_multibyte): Remove decl.
18737 (free_misc, interval_free_list, float_block, float_block_index):

18739 (cons_free_list, last_marked_index):
18741 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
18742 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
18743 (mark_backtrace): Define only if BYTE_MARK_STACK.
18744 * xdisp.c (message_enable_multibyte): Now static.
18746 Declare Lisp_Object Q* variables to be 'static' if not exported.
18747 This makes it easier for human readers (and static analyzers)
18748 to see whether these variables are used from other modules.
18749 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
18750 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
18751 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

18754 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
18755 * xmenu.c, xselect.c:
18756 Declare Q* vars static if they are not used in other modules.
18757 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
18758 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
18759 Remove decls of unexported vars.
18760 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
18762 * lisp.h (DEFINE_FUNC): Make sname 'static'.
18764 Make Emacs functions such as Fatom 'static' by default.
18765 This makes it easier for human readers (and static analyzers)
18766 to see whether these functions can be called from other modules.
18767 DEFUN now defines a static function. To make the function external
18768 so that it can be used in other C modules, use the new macro DEFUE.
18769 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
18770 (Finit_image_library):
18771 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
18772 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
18773 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18774 Remove decls, since these functions are now static.
18775 (Funintern, Fget_internal_run_time): New decls, since these functions
18776 were already external.
18778 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
18779 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

18785 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
18786 Mark functions with DEFUE instead of DEFUN,
18787 if they are used in other modules.
18788 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18789 decls for now-static functions.
18790 * buffer.h (Fdelete_overlay): Remove decl.
18791 * callproc.c (Fgetenv_internal): Mark as internal.
18792 * composite.c (Fremove_list_of_text_properties): Remove decl.

18799 * fileio.c (Fmake_symbolic_link): New forward static decl.
18800 * image.c (Finit_image_library): New forward static decl.
18801 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
18802 * intervals.h (Fprevious_property_change):
18803 (Fremove_list_of_text_properties): Remove decls.
18804 * keyboard.c (Fthis_command_keys): Remove decl.
18805 (Fcommand_execute): New forward static decl.
18806 * keymap.c (Flookup_key): New forward static decl.
18807 (Fcopy_keymap): Now static.
18808 * keymap.h (Flookup_key): Remove decl.
18809 * process.c (Fget_process): New forward static decl.
18810 (Fprocess_datagram_address): Mark as internal.

18823 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
18826 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18828 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18829 when at ZV. (Bug#8487)
18831 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18833 * charset.c (Fclear_charset_maps): Use xfree instead of free.
18835 * keyboard.c (parse_tool_bar_item): Likewise.
18836 * sound.c (sound_cleanup, alsa_close): Likewise.
18837 * termcap.c (tgetent): Likewise.
18838 * xfns.c (x_default_font_parameter): Likewise.
18839 * xsettings.c (read_and_apply_settings): Likewise.
18841 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18842 (overrun_check_free): Protoize.
18844 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18846 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18847 since callers should never pass a negative size.
18848 Change the signature to match that of plain 'read' and 'write'; see
18849 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18850 * lisp.h: Update prototypes of emacs_write and emacs_read.
18852 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18854 * xdisp.c (redisplay_window): Don't try to determine the character
18855 position of the scroll margin if the window start point w->startp
18856 is outside the buffer's accessible region. (Bug#8468)
18858 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18860 Fix write-region and its subroutines for buffers > 2GB.
18861 * fileio.c (a_write, e_write): Modify declaration of arguments and
18862 local variables to support buffers larger than 2GB.
18863 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18865 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18866 argument, local variables, and return value.
18868 * lisp.h: Update prototypes of emacs_write and emacs_read.
18870 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18872 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18874 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18876 Fix more problems found by GCC 4.6.0's static checks.
18878 * xdisp.c (vmessage): Use a better test for character truncation.
18880 * charset.c (load_charset_map): <, not <=, for optimization,
18881 and to avoid potential problems with integer overflow.
18882 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18883 * casetab.c (set_identity, shuffle): Likewise.
18884 * editfns.c (Fformat): Likewise.
18885 * syntax.c (skip_chars): Likewise.
18887 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18888 This also lets GCC 4.6.0 generate slightly better loop code.
18890 * callint.c (Fcall_interactively): <, not <=, for optimization.
18891 (Fcall_interactively): Count the number of arguments produced,
18892 not the number of arguments given. This is simpler and lets GCC
18893 4.6.0 generate slightly better code.
18895 * ftfont.c: Distingish more carefully between FcChar8 and char.
18896 The previous code passed unsigned char * to a functions like
18897 strlen and xstrcasecmp that expect char *, which does not
18898 conform to the C standard.
18899 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18900 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18901 char * when the C standard requires it.
18903 * keyboard.c (read_char): Remove unused var.
18905 * eval.c: Port to Windows vsnprintf (Bug#8435).
18906 Include <limits.h>.
18907 (SIZE_MAX): Define if the headers do not.
18908 (verror): Do not give up if vsnprintf returns a negative count.
18909 Instead, grow the buffer. This ports to Windows vsnprintf, which
18910 does not conform to C99. Problem reported by Eli Zaretskii.
18911 Also, simplify the allocation scheme, by avoiding the need for
18912 calling realloc, and removing the ALLOCATED variable.
18914 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18916 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18917 But keep the doprint source code for now, as we might revamp it
18918 and use it again (Bug#8435).
18919 * lisp.h (doprnt): Remove.
18920 * Makefile.in (base_obj): Remove doprnt.o.
18921 * deps.mk (doprnt.o): Remove.
18923 error: Print 32- and 64-bit integers portably (Bug#8435).
18924 Without this change, on typical 64-bit hosts error ("...%d...", N)
18925 was used to print both 32- and 64-bit integers N, which relied on
18926 undefined behavior.
18927 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18928 * lisp.h (error, verror): Mark as printf-like functions.
18929 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18930 Report overflow in size calculations when allocating printf buffer.
18931 Do not truncate output string at its first null byte.
18932 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18933 Truncate the output at a character boundary, since vsnprintf does not
18935 * charset.c (check_iso_charset_parameter): Convert internal
18936 character to string before calling 'error', since %c now has the
18938 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18939 overflow when computing char to be passed to 'error'. Do not
18940 pass Lisp_Object to 'error'; pass the integer instead.
18941 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18942 formatted with plain %d.
18944 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18946 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18948 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18950 * xterm.c (x_catch_errors): Remove duplicate declaration.
18952 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18954 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18956 2011-04-10 Jim Meyering <meyering@redhat.com>
18958 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18959 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18960 return ssize_t not "int", and use size_t as the buffer length.
18961 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18962 * gnutls.h: Update declarations.
18963 * process.c (read_process_output): Use ssize_t, to match.
18964 (send_process): Likewise.
18966 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18968 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18970 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18972 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18973 Use unsigned char, to match FcChar8 type definition.
18975 * xterm.c (handle_one_xevent):
18976 * xmenu.c (create_and_show_popup_menu):
18977 * xselect.c (x_decline_selection_request)
18978 (x_reply_selection_request): Avoid type-punned deref of X events.
18980 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18982 Fix some uses of `int' instead of EMACS_INT.
18983 * search.c (string_match_1, fast_string_match)
18984 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18985 (scan_buffer, find_next_newline_no_quit)
18986 (find_before_next_newline, search_command, Freplace_match)
18987 (Fmatch_data): Make some `int' variables be EMACS_INT.
18989 * xdisp.c (display_count_lines): 3rd argument and return value now
18990 EMACS_INT. All callers changed.
18991 (pint2hrstr): Last argument is now EMACS_INT.
18993 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18994 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18995 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18996 (decode_coding_utf_16, decode_coding_emacs_mule)
18997 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
18998 (decode_coding_ccl, decode_coding_charset)
18999 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19000 (decode_coding_iso_2022, decode_coding_emacs_mule)
19001 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19002 <char_offset, last_offset>: Declare EMACS_INT.

19004 (encode_coding_emacs_mule, encode_invocation_designation)
19005 (encode_designation_at_bol, encode_coding_iso_2022)
19006 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19007 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19009 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19010 (encode_invocation_designation): Last argument P_NCHARS is now
19012 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19013 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19015 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19018 * ccl.c (Fccl_execute_on_string): Declare some variables
19021 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19023 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19025 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19027 * process.c (Fformat_network_address): Doc fix.
19029 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19031 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19033 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19035 * keyboard.c (read_char): Call Lisp function help-form-show,
19036 instead of using internal_with_output_to_temp_buffer.
19037 (Qhelp_form_show): New var.
19038 (syms_of_keyboard): Use DEFSYM macro.
19040 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19047 (list_processes_1): Delete.
19049 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19051 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19053 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19055 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19057 Fix more problems found by GCC 4.6.0's static checks.
19059 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19061 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19063 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19065 * xdisp.c (vmessage): Mark as a printf-like function.
19067 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19069 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19071 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19072 printf-like functions.
19073 (tiff_load): Add casts to remove these marks before passing them
19074 to system-supplied API.
19076 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19078 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19079 This avoids several warnings with gcc -Wstrict-overflow.
19080 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19081 directly, rather than having caller test rule sign. This avoids
19082 some unnecessary tests.
19083 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19084 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19085 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19087 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19088 (xfont_open): Avoid unnecessary tests.
19090 * composite.c (composition_gstring_put_cache): Use unsigned integer.

19099 by using the new macro.
19101 * textprop.c (set_text_properties_1): Change while to do-while,
19102 since the condition is always true at first.
19104 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19105 (interval_deletion_adjustment): Return unsigned value.
19108 * process.c (list_processes_1, create_pty, read_process_output):
19109 (exec_sentinel): Remove vars that were set but not used.
19110 (create_pty): Remove unnecessary "volatile"s.

19113 (read_process_output): Simplify nbytes computation if buffered.
19115 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
19117 * syntax.c (scan_words): Remove var that was set but not used.
19118 (update_syntax_table): Use unsigned instead of int.
19120 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19121 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19122 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19124 * print.c (print_error_message): Avoid int overflow.
19126 * font.c (font_list_entities): Redo for clarity,
19127 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

19142 (wordify): Omit three unnecessary tests.
19144 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19145 All callers changed. This avoids the need for an unused var.
19147 * casefiddle.c (casify_region): Remove var that is set but not used.
19149 * dired.c (file_name_completion): Remove var that is set but not used.
19151 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19153 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19154 (Finsert_file_contents): Remove unnecessary code checking fd.
19156 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19157 Check for integer overflow on size calculations.
19159 * buffer.c (Fprevious_overlay_change): Remove var that is set
19162 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19163 Remove vars that are set but not used.
19164 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19165 (timer_check_2): Mark vars as initialized.
19167 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19169 * image.c (lookup_image): Remove var that is set but not used.
19170 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19172 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19173 that are set but not used.
19175 * xfns.c (make_invisible_cursor): Don't return garbage
19176 if XCreateBitmapFromData fails (Bug#8410).
19178 * xselect.c (x_get_local_selection, x_handle_property_notify):
19179 Remove vars that are set but not used.
19181 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19182 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19184 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19185 Remove var that is set but not used.
19186 (scroll_bar_windows_size): Now size_t, not int.
19187 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19188 Check for overflow.
19190 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19191 (map_tty_color) [!defined MSDOS]: Likewise.
19193 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19195 * coding.c: Remove vars that are set but not used.
19196 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19197 All callers changed.
19198 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19199 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19200 (decode_coding_charset): Remove vars that are set but not used.
19202 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19203 that is set but not used.
19205 * print.c (print_object): Remove var that is set but not used.
19207 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19208 The gnulib version avoids calling malloc in the usual case,
19209 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19210 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19211 * filelock.c (current_lock_owner): Likewise.
19212 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19213 * sysdep.c: Include allocator.h, careadlinkat.h.
19214 (emacs_no_realloc_allocator): New static constant.
19215 (emacs_readlink): New function.
19216 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19217 ../lib/careadlinkat.h.
19219 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19221 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19222 first non-nil return value).

19238 (get_per_char_metric): Remove parameter `f', unused since
19239 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19241 2011-04-02 Jim Meyering <meyering@redhat.com>
19243 do not dereference NULL upon failed strdup
19244 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19245 (ns_get_family): Likewise.
19247 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19249 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19251 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19253 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19256 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19258 Add lexical binding.
19260 * window.c (Ftemp_output_buffer_show): New fun.
19261 (Fsave_window_excursion):
19262 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19264 * lread.c (lisp_file_lexically_bound_p): New function.
19265 (Fload): Bind Qlexical_binding.
19266 (readevalloop): Remove `evalfun' arg.
19267 Bind Qinternal_interpreter_environment.
19268 (Feval_buffer): Bind Qlexical_binding.
19269 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19271 (syms_of_lread): Declare `lexical-binding'.
19273 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19275 * keyboard.c (eval_dyn): New fun.
19276 (menu_item_eval_property): Use it.
19278 * image.c (parse_image_spec): Use Ffunctionp.
19280 * fns.c (concat, mapcar1): Accept byte-code-functions.
19282 * eval.c (Fsetq): Handle lexical vars.
19283 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19284 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19285 (FletX, Flet): Obey lexical binding.
19286 (Fcommandp): Handle closures.
19287 (Feval): New `lexical' arg.
19288 (eval_sub): New function extracted from Feval. Use it almost
19289 everywhere where Feval was used. Look up vars in lexical env.
19291 (Ffunctionp): Move from subr.el.
19292 (Ffuncall): Handle closures.
19293 (apply_lambda): Remove `eval_flags'.
19294 (funcall_lambda): Handle closures and new byte-code-functions.
19295 (Fspecial_variable_p): New function.
19296 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19297 but without exporting it to Lisp.
19299 * doc.c (Fdocumentation, store_function_docstring):
19300 * data.c (Finteractive_form): Handle closures.
19302 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19305 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19307 (exec_byte_code): New function extracted from Fbyte_code to handle new
19308 calling convention for byte-code-functions. Add new byte-codes.
19310 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19312 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19314 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19316 * xdisp.c (redisplay_internal): Fix prototype.
19318 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19320 * xdisp.c (SCROLL_LIMIT): New macro.
19321 (try_scrolling): Use it when setting scroll_limit.
19322 Limit scrolling to 100 screen lines.
19323 (redisplay_window): Even when falling back on "recentering",
19324 position point in the window according to scroll-conservatively,
19325 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19327 (try_scrolling): When point is above the window, allow searching
19328 as far as scroll_max, or one screenful, to compute vertical
19329 distance from PT to the scroll margin position. This prevents
19330 try_scrolling from unnecessarily failing when
19331 scroll-conservatively is set to a value slightly larger than the
19332 window height. Clean up the case of PT below the margin at bottom
19333 of window: scroll_max can no longer be INT_MAX. When aggressive
19334 scrolling is in use, don't let point enter the opposite scroll
19335 margin as result of the scroll.
19336 (syms_of_xdisp) <scroll-conservatively>: Document the
19337 threshold of 100 lines for never-recentering scrolling.
19339 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19341 * dispextern.h (move_it_by_lines):

19344 (message_log_check_duplicate): Remove parameters `prev_bol' and
19345 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19346 (redisplay_internal): Remove parameter `preserve_echo_area',
19347 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19349 * indent.c (Fvertical_motion):
19350 * window.c (window_scroll_pixel_based, Frecenter):
19351 Don't pass `need_y_p' to `move_it_by_lines'.
19353 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19355 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19356 steal a few bits to be more compact.
19357 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19358 Remove unneeded casts.
19360 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19362 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19364 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19365 binding" message (bug#7967).
19367 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19369 Fix more problems found by GCC 4.6.0's static checks.
19371 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19372 Remove unused local var.
19374 * editfns.c (Fmessage_box): Remove unused local var.
19376 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19377 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19378 Omit unused local vars.
19379 * window.c (shrink_windows): Omit unused local var.
19380 * menu.c (digest_single_submenu): Omit unused local var.
19381 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19382 Omit unused local var.
19384 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19385 Don't assume string length fits in int.
19386 (keyremap_step, read_key_sequence): Use size_t for sizes.
19387 (read_key_sequence): Don't check last_real_key_start redundantly.
19389 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19390 instead of alloca (Bug#8344).
19392 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19393 (Fbacktrace_frame): Don't assume nframes fits in int.
19395 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19397 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19400 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19402 * cm.c (calccost): Turn while-do into do-while, for clarity.
19404 * keyboard.c (syms_of_keyboard): Use the same style as later
19405 in this function when indexing through an array. This also
19406 works around GCC bug 48267.
19408 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19410 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19412 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19413 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19415 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19416 This avoids undefined behavior on integer overflow, and is a bit
19417 more convenient anyway since it is compared to a size_t variable.
19419 Variadic C functions now count arguments with size_t, not int.
19420 This avoids an unnecessary limitation on 64-bit machines, which
19421 caused (substring ...) to crash on large vectors (Bug#8344).

19431 * fns.c (concat): Likewise.
19432 * frame.c (x_set_frame_parameters): Likewise.
19433 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19434 0 if not found, not -1. All callers changed.
19436 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19437 (stack_copy_size): Now size_t, not int.
19438 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19440 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19442 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19443 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19444 All callers changed.
19446 * lisp.h (multibyte_char_to_unibyte):
19447 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19448 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19459 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19460 don't set the hook to nil, but remove the offending function instead.
19461 (Qcommand_hook_internal): Remove, unused.
19462 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19463 Vcommand_hook_internal.
19465 * eval.c (enum run_hooks_condition): Remove.
19466 (funcall_nil, funcall_not): New functions.
19467 (run_hook_with_args): Call each function through a `funcall' argument.

19481 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19482 All callers changed.
19484 * w32.c (_wsa_errlist): Use braces for struct initializers.
19486 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

19643 * buffer.c (Fkill_all_local_variables):
19644 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19646 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19647 unconditionally since it does the check itself.
19649 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19651 Fix more problems found by GCC 4.5.2's static checks.
19653 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19654 the first time through the loop, since we know p0 < p1 then.
19655 This also avoids a gcc -Wstrict-overflow warning.
19657 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19658 leading to a memory leak, possible in functions like
19659 load_charset_map_from_file that can allocate an unbounded number
19660 of objects (Bug#8318).
19662 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19663 that could (at least in theory) be that large.
19665 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19666 This is less likely to overflow, and avoids undefined behavior if
19667 overflow does occur. All callers changed. Use strtoul to scan
19668 for the unsigned long integer.
19669 (pint2hrstr): Simplify and tune code slightly.
19670 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

19685 * process.c (Fmake_network_process): Use socklen_t, not int,
19686 where POSIX says socklen_t is required in portable programs.
19687 This fixes a porting bug on hosts like 64-bit HP-UX, where
19688 socklen_t is wider than int (Bug#8277).
19689 (Fmake_network_process, server_accept_connection):
19690 (wait_reading_process_output, read_process_output):
19693 * process.c: Rename or move locals to avoid shadowing.

19703 Make tparam.h and terminfo.c consistent.
19704 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19705 Include tparam.h instead, since it declares them.
19706 * cm.h (PC): Remove extern decl; tparam.h now does this.
19707 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19708 * terminfo.c: Include tparam.h, to check interfaces.
19709 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19710 (tparam): Adjust signature to match interface in tparam.h;
19711 this removes some undefined behavior. Check that outstring and len
19712 are zero, which they always are with Emacs.
19713 * tparam.h (PC, BC, UP): New extern decls.
19715 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19716 (xftfont_open): Rename locals to avoid shadowing.

19734 (composition_update_it): Mark var as initialized.
19735 (find_automatic_composition): Mark vars as initialized,
19736 with a FIXME (Bug#8290).

19740 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
19741 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
19742 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19743 to avoid shadowing.

19755 Fix pointer signedness.
19756 (alsa_choose_format): Remove unused local var.
19757 (wav_play): Initialize a variable to 0, to prevent undefined
19758 behavior (Bug#8278).
19760 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
19762 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
19764 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
19765 clobbering (Bug#8298).
19766 * sysdep.c (sys_subshell): Likewise.
19767 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19769 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19770 This should get cleaned up, so that child_setup has the
19771 same signature on all platforms.
19773 * callproc.c (call_process_cleanup): Now static.
19774 (relocate_fd): Rename locals to avoid shadowing.
19776 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19778 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19779 not to be necessary, and produces flickering.
19781 2011-03-20 Glenn Morris <rgm@gnu.org>
19783 * config.in: Remove file.
19785 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

19830 Define only if needed.
19832 * unexelf.c (unexec): Name an expression,
19833 to avoid gcc -Wbad-function-cast warning.
19834 Use a different way to cause a compilation error if anyone uses
19835 n rather than nn, a way that does not involve shadowing.
19836 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
19838 * deps.mk (unexalpha.o): Remove; unused.

19962 (WORDCHAR_P): Likewise. This one is never needed, but is used

19994 gcpro1, gcpro2, etc.
19995 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19997 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19998 argument, for consistency with GCPRO2_VAR, etc: it is now the
19999 prefix of the variable, not the variable itself. All uses
20001 * dired.c (directory_files_internal, file_name_completion):
20002 Rename locals to avoid shadowing.
20004 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20005 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20006 dired.c's scmp function, had undefined behavior.

20011 current_buffer in scope now, rather than later when the macros
20013 (downcase, upcase1): New static inline functions.
20014 (DOWNCASE, UPCASE1): Reimplement using these functions.
20015 This avoids undefined behavior in expressions like

20067 to suppress a gcc -Wclobbered warning that does not seem to be right.
20068 (MAXPATHLEN): Define only if needed.
20070 * process.c (serial_open, serial_configure): Move decls from here ...
20071 * systty.h: ... to here, so that they can be checked.
20073 * fns.c (get_random, seed_random): Move extern decls from here ...

20430 -Wuninitialized does not deduce are never used uninitialized.
20431 (detect_coding_iso_2022): Initialize a local variable that might
20432 be used uninitialized. Leave a FIXME because it's not clear that
20433 this initialization is needed. (Bug#8211)
20434 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
20435 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):

20466 Move these decls to tparam.h, and make them agree with what
20467 is actually in tparam.c. The previous trick of using incompatible
20468 decls in different modules does not conform to the C standard.
20469 All callers of tparam changed to use tparam's actual API.
20470 * tparam.c (tparam1, tparam, tgoto):
