3 Minor call-process cleanups.
4 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
5 at the same time as other platforms, to simplify analysis.
6 No need for fd0_volatile since we have synch_process_fd.
7 Avoid needless emacs_close; arg is always negative.
9 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
11 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
14 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
16 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
17 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
18 and mouse_face_hidden members to a bitfields.
19 * frame.h (struct frame): Remove set-but-not-used space_width member.
20 (FRAME_SPACE_WIDTH): Remove.
21 * nsterm.m, w32term.c, xterm.c: Adjust users.
22 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
23 member. Adjust users. Convert term_initted, delete_in_insert_mode,
24 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
25 members to a bitfields.

29 Don't let call-process be a zombie factory (Bug#12980).
30 Fixing this bug required some cleanup of the signal-handling code.
31 As a side effect, this change also fixes a longstanding rare race
32 condition whereby Emacs could mistakenly kill unrelated processes,
33 and it fixes a bug where a second C-g does not kill a recalcitrant
34 synchronous process in GNU/Linux and similar platforms.
35 The patch should also fix the last vestiges of Bug#9488,
36 a bug which has mostly been fixed on the trunk by other changes.
37 * callproc.c, process.h (synch_process_alive, synch_process_death)
38 (synch_process_termsig, sync_process_retcode):
39 Remove. All uses removed, to simplify analysis and so that
40 less consing is done inside critical sections.
41 * callproc.c (call_process_exited): Remove. All uses replaced
42 with !synch_process_pid.
43 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
44 These take the role of what used to be in unwind-protect arg.
46 (block_child_signal, unblock_child_signal):
47 New functions, to avoid races that could kill innocent-victim processes.
48 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
49 (call_process_kill): Record killed processes as deleted, so that
50 zombies do not clutter up the system. Do this inside a critical
51 section, to avoid a race that would allow the clutter.
52 (call_process_cleanup): Fix code so that the second C-g works again
53 on common platforms such as GNU/Linux.
54 (Fcall_process): Create the child process in a critical section,
55 to fix a race condition. If creating an asynchronous process,
56 record it as deleted so that zombies do not clutter up the system.
57 Do unwind-protect for WINDOWSNT too, as that's simpler in the
58 light of these changes. Omit unnecessary call to emacs_close
59 before failure, as the unwind-protect code does that.
60 * callproc.c (call_process_cleanup):
61 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
62 * process.c (record_deleted_pid): New function, containing
63 code refactored out of Fdelete_process.
64 (Fdelete_process): Use it.
65 (process_status_retrieved): Remove. All callers changed to use
67 (record_child_status_change): Remove, folding its contents into ...
68 (handle_child_signal): ... this signal handler. Now, this
69 function is purely a handler for SIGCHLD, and is not called after
70 a synchronous waitpid returns; the synchronous code is moved to
71 wait_for_termination. There is no need to worry about reaping
72 more than one child now.
73 * sysdep.c (get_child_status, child_status_changed): New functions.
74 (wait_for_termination): Now takes int * status and bool
75 interruptible arguments, too. Do not record child status change;
76 that's now the caller's responsibility. All callers changed.
77 Reimplement in terms of get_child_status.
78 (wait_for_termination_1, interruptible_wait_for_termination):
79 Remove. All callers changed to use wait_for_termination.
80 * syswait.h: Include <stdbool.h>, for bool.
81 (record_child_status_change, interruptible_wait_for_termination):
83 (record_deleted_pid, child_status_changed): New decls.
84 (wait_for_termination): Adjust to API changes noted above.
86 * bytecode.c, lisp.h (Qbytecode): Remove.
87 No longer needed after 2012-11-20 interactive-p changes.
89 2012-12-03 Eli Zaretskii <eliz@gnu.org>
91 * xdisp.c (redisplay_window): If the cursor is visible, but inside
92 the scroll margin, move point outside the margin. (Bug#13055)
94 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
96 * gtkutil.c (my_log_handler): New function.
97 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).

101 * lisp.h (modify_region): Rename to...
102 (modify_region_1): ...new prototype.
103 * textprop.c (modify_region): Now static. Adjust users.
104 * insdel.c (modify_region): Rename to...
105 (modify_region_1): ...new function to work with current buffer.
106 Adjust comment and users. Use true and false for booleans.
108 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
110 * alloc.c (free_save_value): New function.
111 (safe_alloca_unwind): Use it.
112 * lisp.h (free_save_value): New prototype.
113 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
115 (save_excursion_restore): Adjust to match saved data structure.
116 Use free_save_value to offload some work from GC. Drop obsolete
119 2012-12-03 Chong Yidong <cyd@gnu.org>
121 * fileio.c (Vauto_save_list_file_name): Doc fix.
123 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
125 * w32fns.c: Remove prototype of atof.
126 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
128 (file_dialog_callback): Declared UINT_PTR.
130 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
133 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
134 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
137 2012-12-03 Glenn Morris <rgm@gnu.org>
139 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
141 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
143 Fix xpalloc confusion after memory is exhausted.
144 * alloc.c (xpalloc): Comment fix.
145 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
146 and signals an error, do not clear charset_table_size, as
147 charset_table is still valid.
148 * doprnt.c (evxprintf): Clear *BUF after freeing it.
150 Use execve to avoid need to munge environ (Bug#13054).
151 * callproc.c (Fcall_process):
152 * process.c (create_process):
153 Don't save and restore environ; no longer needed.
154 * callproc.c (child_setup):
155 Use execve, not execvp, to preserve environ.
157 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
159 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
161 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
163 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
164 display for sliced images (Bug#10500).
166 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
168 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
170 * doc.c (Fdocumentation): Re-add handling of function-documentation,
171 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
173 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
175 * xdisp.c (window_outdated): Remove eassert since it hits
176 some suspicious corner cases (see Bug#13007 and Bug#13012).
177 (mode_line_update_needed): New function.
178 (redisplay_internal, redisplay_window): Use it.
179 (ensure_selected_frame): New function.

181 (redisplay_internal): Move comment about buffer_shared...
182 (buffer_shared_and_changed): ...near to its real use.
184 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
186 * callproc.c (Fcall_process): Don't misreport vfork failure.
188 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
190 * callproc.c (Fcall_process): Fix vfork portability problems.
191 Do not assume that fd[0], count, filefd, and save_environ survive
192 vfork. Fix bug whereby wrong errno value could be reported for
193 pipe failure. Some minor cleanups, too, as follows. Move buf and
194 bufsize to the context where they're needed. Change new_argv to
195 be of type char **, as this is more convenient and avoids casts.
196 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
197 Now local constants, not macros.
199 2012-11-18 Kenichi Handa <handa@gnu.org>
201 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
202 for the variable "f".
204 2012-11-13 Kenichi Handa <handa@gnu.org>
206 * font.c (font_unparse_xlfd): Exclude special characters from the
207 generating XLFD name.

249 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
250 between bpos_covered and bpos_max. This fixes cursor display when
251 several display strings follow each other.
253 * .gdbinit (pgx): If the glyph's object is a string, display the
254 pointer to string data, rather than the value of the string object
255 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
257 * indent.c (Fvertical_motion): If the starting position is covered
258 by a display string, return to one position before that, to avoid
259 overshooting it inside move_it_to. (Bug#12930)
261 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

273 * xterm.h (struct x_output): Drop outdated #if 0 code.
274 Use bitfields for explicit_parent, asked_for_visible,
275 has_been_visible and net_wm_state_hidden_seen members.

286 * dired.c: Assume HAVE_DIRENT_H.
287 (NAMLEN): Remove, replacing with ...
288 (dirent_namelen): New function. All uses changed. Use the GNU macro
289 _D_EXACT_NAMELEN if available, as it's faster than strlen.
290 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
291 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
292 * makefile.w32-in (DIR_H): Remove. All uses replaced with
294 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
295 * ndir.h: Rename to ../nt/inc/dirent.h.

302 * xftfont.c (xftfont_open): Remove duplicate assignment.
304 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
306 * alloc.c (Fgarbage_collect): Unblock input after clearing
307 gc_in_progress to avoid note_mouse_highlight glitch with GC.
308 * frame.h (FRAME_MOUSE_UPDATE): New macro.
309 * msdos.c (IT_frame_up_to_date): Use it here...
310 * w32term.c (w32_frame_up_to_date): ...here...
311 * xterm.c (XTframe_up_to_date): ...and here...
312 * nsterm.m (ns_frame_up_to_date): ...but not here.
313 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
315 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

321 (update_menu_bar, update_tool_bar): Use it to
322 simplify large 'if' statements.
323 (redisplay_internal): Generalize commonly used
324 'tail' and 'frame' local variables.
326 2012-11-22 Eli Zaretskii <eliz@gnu.org>
328 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
329 with Windows system header.
331 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
333 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

357 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
358 Define for the MSVC compiler.
360 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
362 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
363 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
364 dostounix_filename. Prevents crashes down the road, because
365 dostounix_filename assumes it gets a unibyte string. Reported by
366 Michel de Ruiter <michel@sentient.nl>, see
367 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

409 Rename cygwin_convert_path* to cygwin_convert_file_name*.
411 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
413 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
415 2012-11-18 Eli Zaretskii <eliz@gnu.org>
417 * w32select.c: Include w32common.h before w32term.h, so that
418 windows.h gets included before w32term.h uses some of its
421 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
423 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

447 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
449 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
450 * callproc.c (relocate_fd): Assume F_DUPFD.
451 * emacs.c, term.c (O_RDWR): Remove.
452 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
453 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
454 * nsterm.m: Assume <fcntl.h> exists.
455 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
456 (create_pty, Fmake_network_process, server_accept_connection)
457 (wait_reading_process_output, init_process_emacs):
459 (wait_reading_process_output): Put in a special case for WINDOWSNT
460 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
461 It's not clear this is needed, but it's a more-conservative change.
462 (create_process): Assume FD_CLOEXEC.
463 (create_process, create_pty): Assume O_NOCTTY.
464 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.

468 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
470 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
471 lack it, since gnulib guarantees this.
472 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
474 2012-11-17 Eli Zaretskii <eliz@gnu.org>
476 * w32.c (faccessat): Pretend that directories have the execute bit
477 set. Emacs expects that, e.g., in files.el:cd-absolute.
479 * w32proc.c (create_child): Don't clip the PID of the child
480 process to fit into an Emacs integer, as this is no longer a
482 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
483 reaping only the process specified by PID argument, if that is
484 positive. Use PID instead of dead_child to know which process to
485 reap. Wait for the child to die only if WNOHANG is not in
487 (sys_select): Don't set dead_child.
489 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
490 as it is no longer needed.
492 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
494 (record_child_status_change): Remove the setting of
495 record_at_most_one_child for the !WNOHANG case.
497 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
499 Fix problems in ns port found by static checking.
500 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
501 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
502 not to process group.
503 (ns_select): Use emacs_write, not write, as that's more robust
504 in the presence of signals.
505 (fd_handler:): Check for read errors.
507 2012-11-16 Glenn Morris <rgm@gnu.org>
509 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
511 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
513 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
515 2012-11-16 Eli Zaretskii <eliz@gnu.org>
517 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
518 use the same value of thread handle.
519 (start_timer_thread): If the timer thread exited (due to error),
520 clean up by closing the two handles it used. Duplicate the caller
521 thread's handle here, so it gets duplicated only once, when
522 launching the timer thread. Set priority of the timer thread, not
524 (getitimer): Don't duplicate the caller thread's handle here.
527 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
529 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
532 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
534 Remove no-longer-used pty_max_bytes variable.
535 * process.c (pty_max_bytes): Remove; unused.
536 (send_process): Do not set it.
538 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
540 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
543 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
545 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
546 This follows up on the 2012-09-29 patch that removed indirection
547 for the 'function' field. Reported by Sergey Vinokurov in
548 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
550 2012-11-14 Eli Zaretskii <eliz@gnu.org>
552 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
553 different name, as the MS runtime does not have such a function,
554 and probably never will.) All callers changed. Ignore DIRFD
555 value if PATH is an absolute file name, to match Posix spec
556 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
559 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
561 * xdisp.c (echo_area_display, redisplay_internal):
562 Omit redundant check whether frame_garbaged is set.
564 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
566 Use faccessat, not access, when checking file permissions (Bug#12632).
567 This fixes a bug that has been present in Emacs since its creation.
568 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
569 which must set some sort of record. (Torek's bug report was against
570 a predecessor of GNU Emacs, but GNU Emacs happened to have the
571 same common flaw.) See Torek's Usenet posting
572 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
573 Posted: Fri Apr 8 14:18:56 1983.
574 * Makefile.in (LIB_EACCESS): New macro.
576 * callproc.c (init_callproc):
577 * charset.c (init_charset):
578 * fileio.c (check_existing, check_executable, check_writable)
580 * lread.c (openp, load_path_check):
581 * process.c (allocate_pty):
583 Use effective UID when checking permissions, not real UID.
584 * callproc.c (init_callproc):
585 * charset.c (init_charset):
586 * lread.c (load_path_check, init_lread):
587 Test whether directories are accessible, not merely whether they exist.
588 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
589 * fileio.c (check_existing, check_executable, check_writable)
591 Use symbolic names instead of integers for the flags, as they're
593 (check_writable): New arg AMODE. All uses changed.
594 Set errno on failure.
595 (Ffile_readable_p): Use faccessat, not stat + open + close.
596 (Ffile_writable_p): No need to call check_existing + check_writable.
597 Just call check_writable and then look at errno. This saves a syscall.
598 dir should never be nil; replace an unnecessary runtime check
599 with an eassert. When checking the parent directory of a nonexistent
600 file, check that the directory is searchable as well as writable, as
601 we can't create files in unsearchable directories.
602 (file_directory_p): New function, which uses 'stat' on most platforms
603 but faccessat with D_OK (for efficiency) if WINDOWSNT.
604 (Ffile_directory_p, Fset_file_times): Use it.
605 (file_accessible_directory_p): New function, which uses a single
606 syscall for efficiency.
607 (Ffile_accessible_directory_p): Use it.
608 * xrdb.c (file_p): Use file_directory_p.
609 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
610 * lread.c (openp): When opening a file, use fstat rather than
611 stat, as that avoids a permissions race. When not opening a file,
612 use file_directory_p rather than stat.
613 (dir_warning): First arg is now a usage string, not a format.
614 Use errno. All uses changed.
615 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
616 that merely introduced a race.
617 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
618 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
619 and similarly for the other O_* flags.
620 * w32.c (sys_faccessat): Rename from sys_access and switch to
621 faccessat's API. All uses changed.
622 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
623 (magic_db): Rename from magic_file_p.
624 (magic_db, search_magic_path): Return an XrmDatabase rather than a
625 char *, so that we don't have to test for file existence
626 separately from opening the file for reading. This removes a race
627 fixes a permission-checking problem, and simplifies the code.
629 (file_p): Remove; no longer needed.
631 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
633 Omit glyphs initialization at startup.
634 * dispnew.c (glyphs_initialized_initially_p): Remove.
635 (adjust_frame_glyphs_initially): Likewise. Adjust users.
636 (Fredraw_frame): Move actual code from here...
637 (redraw_frame): ...to here. Add eassert. Adjust comment.
638 (Fredraw_display): Use redraw_frame.
639 * xdisp.c (clear_garbaged_frames): Likewise.
641 2012-11-13 Eli Zaretskii <eliz@gnu.org>
643 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
644 passed to pint2str and pint2hrstr to be at most the size of the
645 frame's decode_mode_spec_buffer. This avoids crashes with very
646 large values of FIELD_WIDTH argument to decode_mode_spec.
649 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
651 Fix a race with verify-visited-file-modtime (Bug#12863).
652 Since at least 1991 Emacs has ignored an mtime difference of no
653 more than one second, but my guess is that this was to work around
654 file system bugs that were fixed long ago. Since the race is
655 causing problems now, let's remove that code.
656 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
657 whose time stamp is off by no more than a second. Insist that the
658 file time stamps match exactly.
660 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
662 * frame.h (struct frame): Convert external_tool_bar member to
663 1-bit unsigned bitfield.
664 * termhooks.h (struct terminal): Remove mouse_moved member since
665 all users are long dead. Adjust comment on mouse_position_hook.
667 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
669 Simplify by using FOR_EACH_FRAME here and there.
670 * frame.c (next_frame, prev_frame, other_visible_frames)
671 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
672 * w32term.c (x_window_to_scroll_bar): Likewise.
673 * window.c (window_list): Likewise.
674 * xdisp.c (x_consider_frame_title): Likewise.
675 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
676 * xfns.c (x_window_to_frame, x_any_window_to_frame)
677 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
678 * xmenu.c (menubar_id_to_frame): Likewise.
679 * xselect.c (frame_for_x_selection): Likewise.
680 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
681 (x_window_to_menu_bar): Likewise.
682 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
684 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
686 * data.c (Qdefalias_fset_function): Now static.
688 Another tweak to vectorlike_header change.
689 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
690 Remove, and replace all uses with ...
691 (next_in_free_list, set_next_in_free_list):
692 New functions, which respect C's aliasing rules better.
694 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
696 * window.c (list4i): Rename from 'quad'. All uses changed.
697 Needed because <sys/types.h> defines 'quad' on Solaris 10.
699 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
701 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
702 warning about mixing declarations and code in ISO C90.
704 2012-11-10 Martin Rudalics <rudalics@gmx.at>
706 * window.c (Fsplit_window_internal): Set combination limit of
707 new parent window to t iff Vwindow_combination_limit is t;
708 fixing a regression introduced with the change from 2012-09-22.
709 (Fset_window_combination_limit): Fix doc-string.
711 2012-11-10 Eli Zaretskii <eliz@gnu.org>
713 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
714 amount when the scroll margins are too large. When scrolling
715 backwards in the buffer, give up if cannot reach point or the
716 scroll margin within a reasonable number of screen lines.
717 Fixes point position in window under scroll-up/down-aggressively when
718 point is positioned many lines beyond the window top/bottom.
721 * ralloc.c (relinquish): If real_morecore fails to return memory
722 to the system, don't crash; instead, leave the last heap
723 unchanged and return. (Bug#12774)
725 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
727 * lisp.h (AUTOLOADP): New macro.
728 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
729 * data.c (Ffset): Remove special ad-advice-info handling.
730 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
732 (Finteractive_form): Simplify.
733 (Fquo): Don't insist on having at least 2 arguments.
734 (Qdefalias_fset_function): New var.
736 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
738 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
740 * nsfont.m (Qcondensed, Qexpanded): New variables.
741 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
742 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
744 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
746 Fix recently introduced crash on MS-Windows (Bug#12839).
747 * w32term.h (struct scroll_bar): Use convenient header.
748 (SCROLL_BAR_VEC_SIZE): Remove.
749 * w32term.c (x_scroll_bar_create): Use VECSIZE.
751 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
753 Tweak last vectorlike_header change.
754 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
755 vectorlike object on the free list. This is introduced to avoid
756 some (but not all) pointer casting and aliasing problems, see
757 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
758 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
760 (xvectype, xvecsize): Use them to examine Lisp_Object values.
762 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
764 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
765 been removed, so remove them here also.
767 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
769 * doc.c (Fdocumentation): Handle new property
770 dynamic-docstring-function to replace the old ad-advice-info.
772 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
774 * fns.c (Qeql, hashtest_eq): Now static.
776 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
778 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
779 * fns.c (hashfn_eq, hashfn_eql, sxhash):
780 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
781 * buffer.c (compare_overlays): Use XLI rather than XHASH.
783 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
785 Use same hash function for hashfn_profiler as for hash_string etc.
786 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
787 * lisp.h (sxhash_combine): New inline function, with the contents
788 of the old SXHASH_COMBINE.
789 * profiler.c (hashfn_profiler): Use it, instead of having a
790 special hash function containing a comparison that always yields 1.
792 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
794 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
795 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
796 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
799 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
801 * image.c (xpm_make_color_table_h): Fix compiler error because
802 make_hash_table changed.
804 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
806 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
808 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
810 Use ad-hoc comparison function for the profiler's hash-tables.
811 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
812 (make_log): Use them.
813 (handle_profiler_signal): Don't inhibit quit any longer since we don't
814 call Fequal any more.
815 (Ffunction_equal): New function.
816 (cmpfn_profiler, hashfn_profiler): New functions.
817 (syms_of_profiler): Initialize them.
818 * lisp.h (struct hash_table_test): New struct.
819 (struct Lisp_Hash_Table): Use it.
820 * alloc.c (mark_object): Mark hash_table_test fields of hash tables.
821 * fns.c (make_hash_table): Take a struct to describe the test.
822 (cmpfn_eql, cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
823 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
824 (hash_lookup, hash_remove_from_table): Move assertion checking of
825 hashfn result here. Check hash-equality before calling cmpfn.
826 (Fmake_hash_table): Adjust call to make_hash_table.
827 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
828 (syms_of_fns): Initialize them.
829 * emacs.c (main): Move syms_of_fns earlier.

837 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
838 value of w32-scroll-lock-modifier is neither nil nor one of the
839 known key modifiers. (Bug#12806)
841 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
843 Shrink struct vectorlike_header to the only size field.
844 * lisp.h (enum pvec_type): Avoid explicit enum member values.
846 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
847 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
848 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
849 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
850 information from the vector header. Adjust comment.
851 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
852 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
854 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
855 (struct vectorlike_header): Remove next member. Adjust comment.
856 (struct Lisp_Subr): Add convenient header. Adjust comment.
857 (allocate_pseudovector): Adjust prototype.
858 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
859 (sweep_string, lisp_malloc): Remove useless prototypes.
860 (enum mem_type): Adjust comment.
861 (NEXT_IN_FREE_LIST): New macro.
862 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
863 (Fmake_bool_vector): Likewise.
864 (struct large_vector): New type to represent allocation unit for
865 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
866 (large_vectors): Change type to struct large_vector.
867 (allocate_vector_from_block): Simplify.
868 (PSEUDOVECTOR_NBYTES): Replace with...
869 (vector_nbytes): ...new function. Adjust users.
870 (sweep_vectors): Adjust processing of large vectors.
871 (allocate_vectorlike): Likewise.
872 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
873 Add easserts. Adjust XSETPVECTYPESIZE usage.
874 (allocate_buffer): Use BUFFER_PVEC_INIT.
875 (live_vector_p): Adjust to match large vector.
876 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
877 * buffer.h (struct buffer): Add next member.
878 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
880 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
881 * fns.c (internal_equal): Adjust to match enum pvec_type change.

885 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
886 (xvecsize): New command.
888 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
890 * keyboard.c (event_to_kboard): Do not dereference
891 frame_or_window field of SELECTION_REQUEST_EVENT
892 and SELECTION_CLEAR_EVENT events (Bug#12814).
893 * xterm.h (struct selection_input_event): Adjust comment.
895 2012-11-07 Eli Zaretskii <eliz@gnu.org>
897 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
898 such as Scroll Lock, if the respective keys are treated as
899 function keys, not as modifiers. This avoids destroying non-ASCII
900 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
902 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
904 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
906 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
908 Restore some duplicate definitions (Bug#12814).
909 This undoes part of the 2012-11-03 changes. Some people build
910 with plain -g rather than with -g3, and they need the duplicate
911 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
912 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
913 Define as macros, as well as as enums or as constants.
915 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
917 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
918 to keypad keys (Bug#12816).
920 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
922 Minor adjustments of recently-changed frame functions.
923 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
924 known to be a frame (we're in the FRAMEP branch).
925 * lisp.h (Qframep): Remove decl. frame.h declares this.
926 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
927 since they're meant for Lisp fixnum values.
929 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
931 * window.c (Fwindow_combination_limit): Revert to the only
932 required argument and adjust docstring as suggested in
933 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
934 by Martin Rudalics <rudalics@gmx.at>.
936 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
938 Widely used frame validity and checking functions.
939 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
940 * frame.c (decode_live_frame, decode_any_frame): New functions.
941 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
942 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
943 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
944 (Fframe_pointer_visible_p): Use decode_any_frame.
945 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
946 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
947 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
948 (Fframe_focus): Likewise. Allow zero number of arguments.
950 (frame_buffer_list, frame_buffer_predicate): Remove.
951 * lisp.h (frame_buffer_predicate): Remove prototype.
952 * buffer.c (Fother_buffer): Use decode_any_frame.
953 * xdisp.c (Ftool_bar_lines_needed): Likewise.
954 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
955 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
956 (Fclose_font, Ffont_info): Use decode_live_frame.
957 * fontset.c (check_fontset_name): Likewise.
958 * terminal.c (Fframe_terminal): Likewise.
959 * w32fns.c (check_x_frame): Likewise.
960 * window.c (Fminibuffer_window, Fwindow_at)
961 (Fcurrent_window_configuration): Likewise.
962 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
963 Likewise. Allow zero number of arguments. Adjust docstring.
964 * dispnew.c (Fredraw_frame): Likewise.
965 * xfaces.c (frame_or_selected_frame): Remove.
966 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
967 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
968 (Fframe_face_alist): Use decode_live_frame.
969 * xfns.c (check_x_frame): Likewise.
971 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
973 * window.c (quad): New function.
974 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
975 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
976 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
977 (Fwindow_line_height): Use it.
978 (Fwindow_fringes): Use list3.
979 (Fwindow_scroll_bars): Use list4.
980 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
981 (Fwindow_combination_limit): Allow zero number of arguments.
983 2012-11-05 Eli Zaretskii <eliz@gnu.org>
985 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
987 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
988 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
989 file descriptor 2 for standard error. (Bug#12805)
991 2012-11-05 Chong Yidong <cyd@gnu.org>
993 * process.c (wait_reading_process_output): Revert previous change.
995 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
997 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
998 This removes code that has been obsolete since around 1990.
999 * callproc.c (Fcall_process):
1001 * process.c (create_process):
1002 * term.c (dissociate_if_controlling_tty):
1003 Assume setsid exists.
1004 * callproc.c (child_setup): Assume setpgid exists and behaves as
1005 per POSIX.1-1988 or later.
1006 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1007 * emacs.c (shut_down_emacs):
1008 * sysdep.c (sys_suspend, init_foreground_group):
1009 Assume getpgrp behaves as per POSIX.1-1998 or later.
1010 * msdos.c (setpgrp): Remove.
1011 (tcgetpgrp, setpgid, setsid): New functions.
1012 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1013 * term.c (no_controlling_tty): Remove; unused.
1014 * w32proc.c (setpgrp): Remove.
1015 (setsid, tcgetpgrp): New functions.
1017 Simplify by assuming __fpending.
1018 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1019 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1020 Do not assume that __fpending's result fits in int.
1022 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1024 Remove EMACS_OUTQSIZE+sleep hack.
1025 * dispnew.c (update_frame_1): Remove hack for terminals slower
1026 than 2400 bps, which throttled Emacs by having it sleep.
1027 This code hasn't worked since at least 2007, when the multi-tty stuff
1028 was added, and anyway those old terminals are long dead.
1029 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1030 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1032 Fix data-loss with --version (Bug#9574).
1033 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1034 as we can't assume that emacs_strerror is initialized, and strerror
1035 is good enough here.
1036 (main): Invoke atexit earlier, to catch earlier instances of
1037 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1039 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1041 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1042 (keyDown): Remap keypad keys to X11 virtual key codes.
1044 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1046 Fix data-loss with --batch (Bug#9574).
1047 * emacs.c: Include <close-stream.h>.
1048 (close_output_streams): New function.
1049 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1050 and handles errors appropriately.
1051 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1054 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1055 The symptom is a diagnostic "GLib-WARNING **: In call to
1056 g_spawn_sync(), exit status of a child process was requested but
1057 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1058 waitpid(), so exit status can't be returned." The diagnostic
1059 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1060 The real bug is a race condition between Emacs and glib: Emacs
1061 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1062 so that glib can't find it. Work around the bug by invoking
1063 waitpid only on subprocesses that Emacs itself creates.
1064 * process.c (create_process, record_child_status_change):
1065 Don't use special value -1 in pid field, as the caller now must
1066 know the pid rather than having the callee infer it.
1067 The inference was sometimes incorrect anyway, due to another race.
1068 (create_process): Set new 'alive' member if child is created.
1069 (process_status_retrieved): New function.
1070 (record_child_status_change): Use it.
1071 Accept negative 1st argument, which means to wait for the
1072 processes that Emacs already knows about. Move special-case code
1073 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1074 processes that have already been waited for, by testing and
1075 clearing new 'alive' member.
1076 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1077 now does this internally.
1078 (handle_child_signal): Let record_child_status_change do all
1079 the work, since we do not want to reap all exited child processes,
1080 only the child processes that Emacs itself created.
1081 * process.h (Lisp_Process): New boolean member 'alive'.
1083 Omit duplicate definitions no longer needed with gcc -g3.
1084 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1085 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1086 Define only as macros. There's no longer any need to also define
1087 these symbols as enums or as constants, since we now assume
1088 gcc -g3 when debugging.
1090 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1092 * lisp.mk: Adjust comments to the fact that term/internal is now
1093 loaded from loadup.el.
1095 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1096 (msdos_fatal_signal): New function.
1097 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1100 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1101 for GCC versions before 4.
1102 (emacs_raise): Define to call msdos_fatal_signal.
1104 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1105 iterator when starting in the middle of a display or overlay
1108 2012-11-03 Chong Yidong <cyd@gnu.org>
1110 * process.c (wait_reading_process_output): Clean up the last
1113 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1115 * process.c (wait_reading_process_output): Avoid a race condition
1116 with SIGIO delivery (Bug#11536).
1118 2012-11-03 Chong Yidong <cyd@gnu.org>
1120 * buffer.c (cursor_type): Untabify docstring.
1122 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1124 * frame.h (struct frame): Drop can_have_scroll_bars member
1125 which is meaningless for a long time. Adjust comments.
1126 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1127 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1129 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1131 * window.c (decode_next_window_args): Update window arg after
1132 calling decode_live_window and so fix crash reported at
1133 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1134 by Juanma Barranquero <lekktu@gmail.com>.
1135 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1136 * font.c (Ffont_at): Likewise.
1138 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1140 * widget.c (resize_cb): New function.
1141 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1142 (EmacsFrameResize): Check if all is up to date before changing frame
1145 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1147 Implement backtrace output for fatal errors on MS-Windows.
1148 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1149 (BACKTRACE_LIMIT_MAX): New macro.
1150 (w32_backtrace): New function.
1151 (emacs_abort): Use w32_backtrace when the user chooses not to
1152 attach a debugger. Update the text of the abort dialog.
1154 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1156 Window-related stuff cleanup here and there.
1157 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1158 Use decode_any_window.
1159 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1160 * xdisp.c (Fformat_mode_line): Likewise.
1161 * font.c (Ffont_at): Use decode_live_window.
1162 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1163 * window.c (decode_next_window_args): Likewise.
1164 (decode_any_window): Remove static.
1165 * window.h (decode_any_window): Add prototype.
1166 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1167 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1170 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1172 Remove pad from struct input_event.
1173 * termhooks.h (struct input_event): Remove padding field.
1175 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1176 member is never cons for a long time. Adjust comment.
1177 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1178 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1179 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1180 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1182 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1184 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1186 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1188 Fix crash when using Emacs as commit editor for git (Bug#12697).
1189 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1190 and it is configured in conf_post.h.
1191 (Fcall_process): Don't invoke both setsid and setpgid; the former
1192 is enough, if it exists.
1193 * callproc.c (Fcall_process, child_setup):
1194 * process.c (create_process): Use setpgid.
1195 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1197 * dispnew.c (init_display): Initialize the foreground group
1198 if we are running a tty display.
1199 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1200 * lisp.h (init_foreground_group): New decl.
1201 * sysdep.c (inherited_pgroup): New static var.
1202 (init_foreground_group, tcsetpgrp_without_stopping)
1203 (narrow_foreground_group, widen_foreground_group): New functions.
1204 (init_sys_modes): Narrow foreground group.
1205 (reset_sys_modes): Widen foreground group.
1207 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1209 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1211 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1213 * minibuf.c (read_minibuf): Restore current buffer since
1214 choose_minibuf_frame calling Fset_frame_selected_window may
1215 change it (Bug#12766).
1217 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1219 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1221 2012-10-30 Kenichi Handa <handa@gnu.org>
1223 * font.c (Ffont_at): If WINDOW is specified and it is not
1224 displaying the current buffer, signal an error.
1226 2012-10-29 Daniel Colascione <dancol@dancol.org>
1228 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1229 In preparation for fixing bug#12739, move these functions from
1232 * coding.h, coding.c: ... to here, and compile them only when
1233 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1234 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1236 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1238 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1239 (timer_loop, getitimer, setitimer): Use it instead of
1240 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1242 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1245 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1247 * nsterm.m (NO_APPDEFINED_DATA): New define.
1248 (last_appdefined_event_data): New variable
1249 (last_appdefined_event): Remove.
1250 (ns_select): Initialize t from last_appdefined_event_data instead
1251 of [last_appdefined_event data1].
1252 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1253 remove last_appdefined_event (Bug#12698).
1255 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1257 * frame.c (x_set_font): Catch internal error.
1259 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1261 Avoid overflow in w32 implementation of interval timers.
1262 When possible, for ITIMER_PROF count only times the main thread
1264 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1265 'volatile ULONGLONG' types. All the other data which was
1266 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1267 (GetThreadTimes_Proc): New typedef.
1268 (w32_get_timer_time): New function, returns a suitable time value
1270 (timer_loop): Enter critical section when accessing ULONGLONG
1271 values of the itimer_data struct, as these accesses are no longer
1272 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1273 Remove unused variable.
1274 (init_timers): Initialize s_pfn_Get_Thread_Times.
1275 (start_timer_thread): Don't assign itimer->caller_thread here.
1276 (getitimer): Assign itimer->caller_thread here.
1277 (setitimer): Always call getitimer to get the value of ticks_now.
1278 (sys_spawnve): Avoid compiler warning about format mismatch.
1280 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1282 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1283 mouse movement events if the menu bar is active. This avoids
1284 producing a busy "hour-glass" cursor by Windows if the mouse
1285 pointer is positioned over a tooltip shown for some menu item.
1287 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1289 Don't assume process IDs fit in int.
1290 * emacs.c (shut_down_emacs) [!DOS_NT]:
1291 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1292 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1293 Use pid_t, not int, to store process IDs, as 'int'
1294 is not wide enough on a few platforms (e.g., AIX and IRIX).
1296 2012-10-23 Kenichi Handa <handa@gnu.org>
1298 The following change is to make face-font-rescale-alist work
1299 correctly for non-ASCII fonts.
1301 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1302 (font_open_for_lface): Handle Vface_font_rescale_alist.
1304 2012-10-23 Chong Yidong <cyd@gnu.org>
1306 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1308 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1310 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1312 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1314 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1317 2012-10-21 Glenn Morris <rgm@gnu.org>
1319 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1321 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1323 Port to OpenBSD 5.1.
1324 * frame.c (Fmouse_position, Fmouse_pixel_position):
1325 * xdisp.c (produce_stretch_glyph):
1326 Declare local vars only when they're needed.
1327 This is clearer and avoids a warning on OpenBSD about unused vars.
1328 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1329 This is safer, and avoids OpenBSD warnings about unused vars.
1330 * keyboard.c (record_menu_key): Remove unnecessary decl.
1331 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1332 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1333 as our definition clashes with OpenBSD's.
1334 * xfaces.c (load_face_colors, check_lface_attrs)
1335 (get_lface_attributes_no_remap, get_lface_attributes)
1336 (lface_fully_specified_p, x_supports_face_attributes_p)
1337 (tty_supports_face_attributes_p, face_fontset, realize_face)
1338 (realize_x_face, realize_tty_face):
1339 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1340 merely Lisp_Object *. This is more informative and avoids
1341 a warning on OpenBSD about accessing beyond an object's size.
1343 2012-10-20 Chong Yidong <cyd@gnu.org>
1345 * lread.c (Fload): Doc fix (Bug#12592).
1347 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1349 * font.c (Ffont_at): Fix previous change.
1351 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1353 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1354 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
1357 * alloc.c (NSTATICS): Decrease to 0x800.
1359 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
1361 * fns.c (Fnreverse): Include the problem element when signalling an
1364 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
1366 * nsterm.m (ns_select): Check writefds before call to
1367 FD_ISSET (Bug#12668).
1369 2012-10-18 Daniel Colascione <dancol@dancol.org>
1371 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1372 (staticpro): If we run out of staticpro slots, die with an
1373 informative error instead of just calling emacs_abort.
1375 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1377 Fix two flaws reported by Dmitry Antipov.
1378 * window.c (Ftemp_output_buffer_show): Remove.
1379 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
1380 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
1382 2012-10-17 Eli Zaretskii <eliz@gnu.org>
1384 * makefile.w32-in ($(BLD)/w32.$(O)):
1385 ($(BLD)/vm-limit.$(O)):
1387 ($(BLD)/unexw32.$(O)):
1388 ($(BLD)/fileio.$(O)):
1389 ($(BLD)/dispnew.$(O)): Update dependencies.
1391 * w32term.h (w32_initialize_display_info, initialize_w32_display):
1394 * w32proc.c: Include ctype.h.
1396 * w32.h (init_environment, check_windows_init_file)
1397 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
1398 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
1399 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
1400 (sys_link): Add prototypes.
1402 * w32.c: Include w32select.h.
1403 (sys_access, e_malloc, sys_select): Add prototypes.

1531 * fileio.c (check_existing): New function.
1532 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it

1534 a file exists. This avoids expensive system calls on MS-Windows.
1537 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.

1631 Use unsigned for counter where wraparound-on-overflow is desired,
1632 since unsigned is guaranteed to have that behavior and signed is not.
1633 (read_char): Use ptrdiff_t for string length.
1634 (get_input_pending): Remove first argument, since it was always
1635 the same pointer-to-int (now pointer-to-boolean) &input_pending,
1636 and behave as if it had that value. Return new value of
1637 input_pending. All callers changed.
1638 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
1639 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
1641 * keymap.c (push_key_description): Omit last arg, which was always 1.
1642 All callers changed.
1644 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
1646 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

1662 Don't include termopts.h.
1664 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
1666 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
1668 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
1670 * commands.h (immediate_quit): Remove duplicate decl.
1672 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
1674 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

1679 2012-10-09 Eli Zaretskii <eliz@gnu.org>
1681 * w32fns.c (w32_last_error): Change the return value to DWORD, to
1682 match what GetLastError returns. Explain why the function is
1685 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
1686 'is_tooltip_frame', to avoid confusion with its global namesake.
1688 2012-10-08 Daniel Colascione <dancol@dancol.org>
1690 * xdisp.c (start_hourglass): Call w32_note_current_window when
1691 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
1692 build that caused Emacs to display the hourglass cursor forever.
1694 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
1695 which is broken under remote desktop, calculate the number of
1696 colors available for a display based on the display's number of
1697 planes and number of bits per pixel per plane. (bug#10397).
1699 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
1701 * nsfont.m (Vfonts_in_cache): New variable.
1702 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
1703 are used. Add cached fonts to Vfonts_in_cache.
1704 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
1706 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
1708 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
1710 (FONT_H): Define after FRAME_H.
1711 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
1712 Update dependencies.
1714 * w32term.c: Remove leftover declaration of keyboard_codepage.
1716 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1718 * makefile.w32-in (FONT_H): Add $(FRAME_H).
1719 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
1720 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
1721 (GLOBAL_SOURCES): Add cygw32.c.
1722 ($(BLD)/unexw32.$(O)):
1724 ($(BLD)/w32console.$(O)):
1725 ($(BLD)/w32fns.$(O)):
1726 ($(BLD)/w32heap.$(O)):
1727 ($(BLD)/w32menu.$(O)):
1728 ($(BLD)/w32proc.$(O)): Add w32common.h.
1730 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
1732 (x_to_w32_color): Don't modify the argument, modify a copy instead.
1734 2012-10-08 Daniel Colascione <dancol@dancol.org>
1736 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
1737 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
1738 accidental message numbering hole. Change other messages to
1741 * w32select.h (HAVE_W32SELECT): Remove.
1743 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
1744 w32common.h instead of w32heap.h.
1746 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
1747 (get_allocation_unit, get_processor_type, get_w32_major_version)
1748 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1749 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1750 (OS_NT, os_subtype, cache_system_info): Move declarations to

1754 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
1755 (w32_minor_version, w32_build_number, w32_subtype):
1756 Remove duplicate definitions.
1758 * w32fns.c: Include w32common.h; include w32heap.h only in
1761 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
1762 Use `report_file_error' instead of `error' in order to better
1763 inform users of what went wrong. Increase NTGUI_UNICODE file
1764 dialog box file name length to 32k, the maximum allowed by the NT
1767 * w32common.h: New file.
1768 (ROUND_UP, ROUND_DOWN, get_page_size)
1769 (get_allocation_unit, get_processor_type, get_w32_major_version)
1770 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1771 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1772 (OS_NT, os_subtype, cache_system_info): Move here.
1774 * unexw32.c, unexcw.c: Include w32common.h.
1776 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1777 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1778 to call syms_of_w32select.
1780 * cygw32.h: Remove obsolete EXFUN declarations.
1782 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

1785 of w32inevt.o from SOME_MACHINE_OBJECTS.
1787 2012-10-08 Daniel Colascione <dancol@dancol.org>
1789 * image.c: Permanent fix for JPEG compilation issue --- limit
1790 jpeglib `boolean' redefinition to Cygwin builds.
1792 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1794 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1796 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1799 2012-10-08 Daniel Colascione <dancol@dancol.org>
1801 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1802 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1803 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1804 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1805 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1806 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1807 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1808 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1809 now a supported configuration.
1811 * Makefile.in: consolidate image variables into LIBIMAGE; add
1812 W32_OBJ and W32_LIBS. Compile new files.
1815 (_DebPrint) declare tracing facility for W32 debugging. We need
1816 to unify tracing later.
1818 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1819 unconditional use of W32 Unicode functions. Cygwin runs only on
1820 100% Unicode operating systems.
1822 * cygw32.c: New file. Define Cygwin-specific facilities.
1823 (Fcygwin_convert_path_to_windows)
1824 (Fcygwin_convert_path_from_windows): New user functions for
1825 accessing Cygwin path-munging routines.
1827 * cygw32.h: New file.
1828 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1829 UTF-16LE strings temporarily inside non-Lisp-visible string
1832 (w32_strerror): Just what it says on the tin.
1834 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1835 also run for Cygwin; both systems have the same problem with using
1836 GUI facilities in a forked child. Also call syms_of_cygw32,
1837 syms_of_w32select in correct places.
1839 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1840 needs fork-then-exec for daemon launching.
1842 * font.h: Include frame.h.
1844 * image.c: Use the image library cache machinery only when we're
1845 compiling for native WINDOWSNT; Cygwin can use shared libraries
1846 like any other Unixlike system.
1848 * keyboard.c: Clarify a comment regarding the input loop.
1850 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1851 functions directly instead of trying to detect at runtime that our
1852 host operating system supports them. We make this change for two
1853 reasons: Cygwin lacks support for the multibyte character
1854 conversion functions used by the legacy menu code, and Cygwin
1855 never needs to rely on non-Unicode APIs.
1857 * unexw32.c (hinst): Declare extern.
1859 * w32.c: Change header order;
1860 (w32_strerror): Move to w32fns.c because we need it for
1861 non-WINDOWSNT builds.
1863 * w32.h: Add #error macro to make sure we don't include w32.h for
1864 Cygwin builds. Remove w32select declarations.
1866 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1867 w32fns.c. w32console.c is WINDOWSNT-only.
1869 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1870 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1872 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1873 (w32_major_version, w32_minor_version, w32_build_number)
1874 (os_subtype, sound_type): Define here
1875 (w32_defined_color): Make color parameter const for consistency
1876 with other _defined_color functions.
1877 (w32_createwindow): Unconditionally call w32_init_class instead of
1878 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1879 through the code is complex and unnecessary because class
1880 registration is practically free.
1881 (w32_name_of_message): New EMACSDEBUG-only function.
1882 (Fset_message_beep): Move here
1883 (Fx_open_connection): Require that the display name for Windows be
1884 "w32" for consistency, emacsclient disambiguation, and maybe, one
1885 day, multi-window-system support.
1886 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1887 Cygwin files for W32 GUI facilities, since these clearly don't
1888 expect Cygwin names.
1889 (_DebPrint): Define.
1890 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1891 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1892 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.

1902 (w32_console_toggle_lock_key): Move to w32fns.c.
1904 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1906 * w32proc.c (_DebPrint): Move to w32fns.c.
1907 * w32select.c: Include string.h, stdio.h for Cygwin.
1908 * w32select.h: New File.
1910 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1912 (w32_message_fd): New variable. Under Cygwin, holds the file
1913 descriptor the system used to tell us about pending thread
1916 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1917 that prevented compilation under non-WINDOWSNT systems.
1919 (w32_initialize): Open /dev/windows and assign it to
1920 w32_message_fd. Provide w32 feature.
1922 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1923 (WM_EMACS_INPUT_READY): add.
1924 (prepend_msg, w32_message_fd): Declare globally.
1927 (keyboard_handle): Use only when WINDOWSNT.
1928 (notify_msg_ready): New function. Posts a message to the main
1929 thread's message queue under CYGWIN, which wakes up the main
1930 thread from select(2) by making the /dev/windows file descriptor
1931 ready. Under WINDOWSNT, it sets an event the same way the old
1934 (post, prepend_msg): Actually call notify_msg_ready instead of
1935 setting the input event directly.
1937 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1939 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1940 but it still has blocs in it, don't return it to the system,
1941 instead of aborting. (Bug#12402)
1943 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1945 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

1980 defined as a macro, as is done in Solaris.
1981 (sys_siglist_entries): New macro.
1982 (save_strsignal): Use it.
1983 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1984 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1986 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1988 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1989 fullscreen/Fullscreen.
1991 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1992 tobar_height is new.
1994 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1995 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1996 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

2005 (canBecomeMainWindow): New function.
2007 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2009 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2011 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2013 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2015 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2016 that time stamps of directories could also be changed.
2017 Don't request the too broad GENERIC_WRITE, only the more restrictive
2018 FILE_WRITE_ATTRIBUTES access rights.
2020 * fileio.c (Fset_file_times): Special-case ignoring errors for
2021 directories only on MSDOS, not on MS-Windows.
2023 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2025 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2027 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2029 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2030 see whether CreateFile failed.
2032 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2034 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2035 to avoid similar races.
2036 * keyboard.c (pending_signals): Now bool, not int.
2038 Port timers to OpenBSD, plus check for timer failures.
2039 OpenBSD problem reported by Han Boetes.
2040 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2042 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2043 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2044 like OpenBSD, which has timer_settime but does not declare it.
2045 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2046 whether to use itimerspec-related primitives. All uses of
2047 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2049 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2051 * profiler.c (handle_profiler_signal): Fix a malloc race
2052 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2054 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2056 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2058 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2060 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2061 consistent with the change in return value of 'safe_strsignal'.
2063 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2065 Prefer plain 'static' to 'static inline' (Bug#12541).
2066 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2067 (bidi_set_sor_type, bidi_push_embedding_level)
2068 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

2073 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2074 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2075 Now 'static', not 'static inline'.
2077 Count overruns when profiling; change units to ns.
2078 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2079 Give extra weight to samples after overruns, to attempt to count
2080 the time more accurately.
2081 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2082 the underlying primitives nominally do ns.
2083 (Fprofiler_cpu_start): Document the change. Mention that
2084 the sampling intervals are only approximate.
2086 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2088 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2090 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2091 case for the special 0 coding-system.
2093 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2094 (Fmake_overlay): Remove redundant tests.
2095 (fix_start_end_in_overlays): Remove redundant recentering.
2097 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2099 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2100 Update dependencies.
2102 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2104 Fix a malloc race condition involving strsignal.
2105 A signal can arrive in the middle of a malloc, and Emacs's signal
2106 handler can invoke strsignal, which can invoke malloc, which is
2107 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2108 Fix it by altering the signal handler so that it does not invoke
2110 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2111 * process.c (status_message): Use const pointer, in case strsignal
2112 is #defined to safe_strsignal.
2113 * sysdep.c (sys_siglist, init_signals): Always define and
2114 initialize a substitute sys_siglist if the system does not define
2115 one, even if HAVE_STRSIGNAL.
2116 (safe_strsignal): Rename from strsignal. Always define,
2117 using sys_siglist. Return a const pointer.
2118 * syssignal.h (safe_strsignal): New decl.
2119 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2121 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2123 * w32proc.c (timer_loop): Fix code that waits for timer
2124 expiration, to avoid high CPU usage.
2126 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2128 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2129 (sweep_weak_table): Remove redundant prototypes.
2131 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2133 * emacs.c: Move the inclusion of TERM_HEADER after including
2134 windows.h on WINDOWSNT. This avoids compilation problems with
2137 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2139 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2140 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2141 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2142 as the previous version used 'void *'.
2144 * ralloc.c (ROUNDUP): Fix last change.
2145 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2148 * w32proc.c <disable_itimers>: New static flag.
2149 (init_timers): Initialize it to zero, after creating the critical
2150 sections used by the timer threads.
2151 (term_timers): Set to 1 before deleting the critical sections.
2152 (getitimer, setitimer): If disable_itimers is non-zero, return an
2153 error indication without doing anything. Reported by Fabrice
2154 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2155 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2157 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2160 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2161 term_ntproc after all the other bookkeeping, to get timers working
2162 as long as possible.
2164 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2166 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2167 Suggested by Juri Linkov in
2168 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2170 Prefer plain 'static' to 'static inline' (Bug#12541).
2171 With static functions, modern compilers inline pretty well by
2172 themselves; advice from programmers often hurts as much as it helps.
2173 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2174 this change shrinks the text size of the Emacs executable by 1.1%
2175 without affecting CPU significantly in my benchmark.
2176 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2256 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2258 Revert the FOLLOW-SYMLINKS change for file-attributes.
2259 Doing it right would require several changes to Tramp, and there's
2260 not enough time to get that tested before the freeze today.
2261 * dired.c (directory_files_internal, Ffile_attributes):
2264 * frame.c (x_report_frame_params): Port better to wider ints.
2265 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2266 or that pointers can be printed in 15 decimal digits.
2267 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

2448 Suggested by Eli Zaretskii in
2449 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
2451 2012-09-30 Eli Zaretskii <eliz@gnu.org>
2453 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2454 HAVE_TIMER_SETTIME is defined.
2456 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2458 Profiler improvements: more-accurate timers, overflow checks.
2459 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2460 signal.h, setjmp.h. Include systime.h instead.
2461 (saturated_add): New function.

2468 All uses changed to store the new value.
2469 (handle_profiler_signal): Rename from sigprof_handler_1,
2470 for consistency with other handlers. Do not check whether
2471 cpu_log is a hash-table if garbage collecting, since it
2472 doesn't matter in that case.

2474 for consistency with other handlers.
2475 (setup_cpu_timer): New function, with much of what used to be in
2476 Fprofiler_cpu_start. Check for out-of-range argument.
2477 Prefer timer_settime if available, and prefer
2478 thread cputime clocks, then process cputime clocks, then
2479 monotonic clocks, to the old realtime clock. Use make_timeval
2480 to round more-correctly when falling back to setitimer.
2481 (Fprofiler_cpu_start): Use it.
2482 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2483 Don't assume that passing NULL as the 2nd argument of setitimer

2486 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2487 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2488 non-fatal signal handlers. Ignore SIGPROF on startup.
2489 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2490 in profiler.c, since sysdep.c now uses it.
2492 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

2547 * charset.c, charset.h (maybe_unify_char): Now static.
2548 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2549 Since this stuff is now private to charset.c, there's no need for
2550 a public macro and no need to inline by hand.

2583 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>

2622 (sigaction): Rewrite to call sys_signal instead of duplicating its
2624 (sys_kill): Improve commentary.
2626 * w32.c (term_ntproc): Accept (and ignore) one argument, for
2627 consistency with a signature of a signal handler. All callers
2629 (init_ntproc): Accept an argument DUMPING. If dumping, don't
2630 install term_ntproc as a signal handler for SIGABRT, as that
2631 should be done by the dumped Emacs.
2633 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
2635 * w32select.c (term_w32select): Protect against repeated
2636 invocation by setting clipboard_owner to NULL after calling

2763 * w32term.c (w32_read_socket): Remove leftover reference to
2764 interrupt_input_pending.
2766 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2768 Do not use SA_NODEFER.
2769 Problem reported by Dani Moncayo in
2770 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2772 * sysdep.c (emacs_abort): Do not reset signal handler.
2773 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2774 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2775 wanted even on POSIXish hosts, and it doesn't work on Windows.
2777 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2779 * xterm.c (x_term_init): Call fixup_locale before and after calling
2780 gtk_init (Bug#12392).
2782 2012-09-23 Chong Yidong <cyd@gnu.org>
2784 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2785 Vdynamic_library_alist.
2787 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2788 (Fgnutls_available_p): Caller changed.
2790 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2791 (Flibxml_parse_xml_region): Likewise.
2793 * dispextern.h (struct image_type): Remove arg from init function.
2795 * image.c (Finit_image_library, lookup_image_type)
2796 (define_image_type): Remove now-unneeded second arg.
2797 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2798 (init_tiff_functions, init_gif_functions, init_svg_functions):
2799 Arglist and w32_delayed_load calling convention changed.
2800 (gs_type): Remove init_gs_functions; there is no such function.
2801 (valid_image_p, make_image): Fix caller to lookup_image_type.
2803 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2805 Simplify and avoid signal-handling races (Bug#12471).
2807 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2808 Avoid recursive loop if there's a fatal error in the function itself.
2809 * atimer.c (pending_atimers):
2810 * blockinput.h: Don't include "atimer.h"; no longer needed.
2811 (interrupt_input_pending): Remove. All uses removed.
2812 pending_signals now counts both atimers and ordinary interrupts.
2813 This is less racy than having three separate pending-signal flags.
2814 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2816 Rename from their upper-case counterparts BLOCK_INPUT,
2817 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2818 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2819 This makes it easier to access volatile variables more accurately.
2820 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2821 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2822 that's more reliable if the code is buggy and sets
2823 interrupt_input_blocked to a negative value. All uses changed.
2824 * atimer.c (deliver_alarm_signal):
2825 Remove. No need to deliver this to the parent; any thread can
2826 handle this signal now. All uses replaced by underlying handler.
2827 * atimer.c (turn_on_atimers):
2828 * dispnew.c (handle_window_change_signal):
2829 * emacs.c (handle_danger_signal):
2830 * keyboard.c (kbd_buffer_get_event):
2831 Don't reestablish signal handler; not needed with sigaction.
2832 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2834 Rework to avoid unnecessary accesses to volatile variables.
2835 (UNBLOCK_INPUT_TO): Now a function.
2836 (totally_unblock_input, unblock_input): New decls.
2837 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2838 (init_data): Remove. Necessary stuff now done in init_signal.
2839 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2840 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2841 (fatal_error_code): Remove; no longer needed.
2842 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2843 it doesn't always backtrace. All uses changed. No need to reset
2844 signal to default, since sigaction and/or die does that for us now.
2845 Use emacs_raise (FOO), not kill (getpid (), FOO).
2846 (main): Check more-accurately whether we're dumping.
2847 Move fatal-error setup to sysdep.c
2848 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2849 * gtkutil.c (xg_get_file_name, xg_get_font):
2850 Remove no-longer-needed signal-mask manipulation.
2851 * keyboard.c, process.c (POLL_FOR_INPUT):
2852 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2853 * keyboard.c (read_avail_input): Remove.
2854 All uses replaced by gobble_input.
2855 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2856 (kbd_buffer_store_event_hold, gobble_input):
2857 (record_asynch_buffer_change) [USABLE_SIGIO]:
2858 (store_user_signal_events):
2859 No need to mess with signal mask.
2860 (gobble_input): If blocking input and there are terminals, simply
2861 set pending_signals to 1 and return. All hooks changed to not
2862 worry about whether input is blocked.
2863 (process_pending_signals): Clear pending_signals before processing
2864 them, in case a signal comes in while we're processing.
2865 By convention callers now test pending_signals before calling us.
2866 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2867 New functions, to support changes to blockinput.h.
2868 (handle_input_available_signal): Now extern.
2869 (reinvoke_input_signal): Remove. All uses replaced by
2871 (quit_count): Now volatile, since a signal handler uses it.
2872 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2873 All callers changed. Block SIGINT only if not already blocked.
2874 Clear sigmask reliably, even if Fsignal returns, which it can.
2875 Omit unnecessary accesses to volatile var.
2876 (quit_throw_to_read_char): No need to restore sigmask.
2877 * keyboard.c (gobble_input, handle_user_signal):
2878 * process.c (wait_reading_process_output):
2879 Call signal-handling code rather than killing ourselves.
2880 * lisp.h: Include <float.h>, for...
2881 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2882 (pending_signals): Now volatile.
2883 (syms_of_data): Now const if IEEE floating point.
2884 (handle_input_available_signal) [USABLE_SIGIO]:
2885 (terminate_due_to_signal, record_child_status_change): New decls.
2886 * process.c (create_process): Avoid disaster if memory is exhausted
2887 while we're processing a vfork, by tightening the critical section
2889 (send_process_frame, process_sent_to, handle_pipe_signal)
2890 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2892 (send_process): No need for setjmp/longjmp any more, since the
2893 SIGPIPE stuff is now gone. Instead, report an error if errno
2895 (record_child_status_change): Now extern. PID and W are now args.
2896 Return void, not bool. All callers changed.
2897 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2898 Remove. All uses removed. This bug should be fixed now in a
2900 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2901 and record the child status change directly. This avoids the
2902 need to futz with the signal mask.
2903 (process_fatal_action): Move here from emacs.c.
2904 (emacs_sigaction_flags): New function, containing
2905 much of what used to be in emacs_sigaction_init.
2906 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2907 caught by emacs, to make races less likely.
2908 (deliver_process_signal): Rename from handle_on_main_thread.
2910 (BACKTRACE_LIMIT_MAX): Now at top level.
2911 (thread_backtrace_buffer, threadback_backtrace_pointers):
2913 (deliver_thread_signal, deliver_fatal_thread_signal):
2914 New functions, for more-accurate delivery of thread-specific signals.
2915 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2916 (deliver_arith_signal): Handle in this thread, not
2917 in the main thread, since it's triggered by this thread.
2918 (maybe_fatal_sig): New function.
2919 (init_signals): New arg DUMPING so that we can be more accurate
2920 about whether we're dumping. Caller changed.
2921 Treat thread-specific signals differently from process-general signals.
2922 Block all signals while handling fatal error; that's safer.
2923 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2925 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2926 Ignore SIGPIPE unless batch.
2927 (emacs_backtrace): Output backtrace for the appropriate thread,
2928 which is not necessarily the main thread.
2929 * syssignal.h: Include <stdbool.h>.
2930 (emacs_raise): New macro.
2931 * xterm.c (x_connection_signal): Remove; no longer needed
2932 now that we use sigaction.
2933 (x_connection_closed): No need to mess with sigmask now.
2934 (x_initialize): No need to reset SIGPIPE handler here, since
2935 init_signals does this for us now.
2937 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2939 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2940 background rect may be larger (Bug#12245).
2942 2012-09-23 Chong Yidong <cyd@gnu.org>
2944 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2946 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2948 * .gdbinit: Just stop at fatal_error_backtrace.
2949 See Stefan Monnier's request in
2950 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2951 Remove no-longer-used query of system type.
2953 2012-09-22 Chong Yidong <cyd@gnu.org>
2955 * search.c (Freplace_match): Doc fix (Bug#12325).
2957 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2959 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2960 (Fline_end_position): Doc fix.
2962 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2964 2012-09-22 Chong Yidong <cyd@gnu.org>
2966 * dispextern.h (struct image_type): Add new slot, storing a type
2967 initialization function.
2969 * image.c (define_image_type): Call the image initializer function
2970 if it is defined. Arguments and return value changed.
2971 (valid_image_p, make_image): Callers changed.
2972 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2973 (gif_type, imagemagick_type, svg_type, gs_type):
2974 Add initialization functions.
2975 (Finit_image_library): Call lookup_image_type.
2976 (CHECK_LIB_AVAILABLE): Macro deleted.
2977 (lookup_image_type): Call define_image_type here, rather than via
2978 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2979 (syms_of_image): Move define_image_type calls for xbm_type and
2980 pbm_type to lookup_image_type.
2982 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2984 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2985 'idle_timers' from here ...
2986 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2987 lists, to avoid infloops when the timer does something stupid,
2988 like reinvoke itself with the same or smaller time-out.
2991 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2993 * window.c (Fsplit_window_internal): Handle only Qt value of
2994 Vwindow_combination_limit separately.
2995 (Qtemp_buffer_resize): New symbol.
2996 (Vwindow_combination_limit): New default value.
2999 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3001 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3002 the new overlay string. (Bug#10159)
3004 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3006 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3007 or that fprintf is async-signal-safe. POSIX doesn't require
3010 2012-09-22 Chong Yidong <cyd@gnu.org>
3012 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3015 2012-09-22 Kenichi Handa <handa@gnu.org>
3017 * composite.c (composition_reseat_it): Handle the case that a
3018 grapheme cluster is not covered by a single font (Bug#12352).
3020 2012-09-21 Chong Yidong <cyd@gnu.org>
3022 * image.c (define_image_type): Avoid adding duplicate types to
3023 image_types (Bug#12463). Suggested by Jörg Walter.
3025 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3027 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3028 (print_load_command_name): Add case LC_DATA_IN_CODE.
3029 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3031 2012-09-21 Glenn Morris <rgm@gnu.org>
3033 * eval.c (Frun_hook_with_args_until_success)
3034 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3036 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3038 * fileio.c (Ffile_selinux_context): Only call freecon when
3039 lgetfilecon succeeded.
3040 (Fset_file_selinux_context): Likewise. (Bug#12444)
3042 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3044 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3045 reordering, locate the cursor by calling set_cursor_from_row; if
3046 that fails, clear the desired glyph matrix before returning a
3047 failure indication to the caller. Fixes leaving garbled display
3048 when fast scrolling with a down-key. (Bug#12403)
3049 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3050 scrolling through multibyte text.
3052 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3054 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3055 calling mark_vectorlike since that's the one that marks the window.
3056 (mark_discard_killed_buffers): Mark the final cdr.
3057 * window.h (struct window): Move prev/next_buffers to the
3058 non-standard fields.
3059 * window.c (make_window): Initialize prev/next_buffers manually.
3061 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3063 Omit unused arg EXPECTED from socket hooks.
3064 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3065 * nsterm.m (ns_term_init):
3066 * termhooks.h (struct terminal.read_socket_hook):
3067 * w32inevt.c (w32_console_read_socket):
3068 * w32term.c (w32_read_socket):
3069 * xterm.c (XTread_socket):
3070 Omit unused arg EXPECTED. All callers changed.
3071 (store_user_signal_events): Return void, not int, since callers no
3072 longer care about the return value. All uses changed.
3074 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3076 * w32gui.h (XParseGeometry): Do not declare.
3078 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3080 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3081 Ignore 'expected'. See Eli Zaretskii in
3082 <http://bugs.gnu.org/12471#8> (last line).
3084 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3085 (XParseGeometry): Now static. Substitute extremal values for
3086 values that are out of range.
3088 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3090 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3092 * nsfns.m (XParseGeometry): Remove.
3093 (Fx_create_frame): Call x_set_offset to correctly interpret
3094 top_pos in geometry.
3096 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3097 (Fx_parse_geometry): If there is a space in string, call
3098 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3100 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3102 * search.c (scan_buffer): Use character positions in calls to
3103 region_cache_forward and region_cache_backward, not byte
3104 positions. (Bug#12196)
3106 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3107 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3109 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3110 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3111 emacs_blocked_malloc, now deleted.
3113 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3115 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3116 The workaround was for improving performance on Solaris 2.4, but
3117 is getting in the way now. Emacs will still work if someone is
3118 still running Solaris 2.4 in a museum somewhere; Sun dropped
3119 support for Solaris 2.4 in 2003.
3120 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3121 * process.c (create_process) [HAVE_WORKING_VFORK]:
3122 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3123 since Emacs no longer uses vfork on that platform.
3125 2012-09-17 Glenn Morris <rgm@gnu.org>
3127 * emacs.c: Use COPYRIGHT.
3129 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3131 Remove configure's --without-sync-input option (Bug#12450).
3132 When auditing signal-handling in preparation for cleaning it up,
3133 I found that SYNC_INPUT has race conditions and would be a real
3134 pain to fix. Since it's an undocumented and deprecated
3135 configure-time option, now seems like a good time to remove it.
3136 Also see <http://bugs.gnu.org/11080#16>.
3137 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3138 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3139 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3140 (malloc_hysteresis):
3141 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3142 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3143 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3144 (dont_register_blocks, bytes_used_when_reconsidered)
3145 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3146 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3147 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3148 Remove. All uses removed.
3149 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3150 implementation, one that depends on whether the new macro
3151 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3153 * atimer.c (run_timers, handle_alarm_signal):
3154 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3155 (handle_async_input, process_pending_signals)
3156 (handle_input_available_signal, init_keyboard):
3157 * nsterm.m (ns_read_socket):
3158 * process.c (wait_reading_process_output):
3159 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3160 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3162 * xterm.c (XTread_socket):
3164 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3165 * eval.c (handling_signal): Remove. All uses removed.
3166 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3167 All uses replaced with the SYNC_INPUT version.
3168 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3170 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3173 * font.c (Ffont_shape_gstring): Remove unused local.
3175 2012-09-16 Glenn Morris <rgm@gnu.org>
3177 * Makefile.in (clean): No longer run nextstep's clean.
3179 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3181 (ns-app): Move here from ns.mk, and simplify.
3182 (clean): Simplify nextstep entry.
3183 * ns.mk: Remove file.
3185 2012-09-17 Kenichi Handa <handa@gnu.org>
3187 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3188 not covert the last few charactes.
3190 2012-09-16 Kenichi Handa <handa@gnu.org>
3192 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3193 here, but just check the validity of glyphs in the glyph-string.
3195 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3197 * window.c (Fwindow_parameter, Fset_window_parameter):
3198 Accept any window as argument (Bug#12452).
3200 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3202 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3203 to ns_term_init to avoid memory leak.
3205 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3206 explicit retain/release.
3207 (ns_term_init): Only allow one display. Initialize outerpool and
3210 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3212 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3213 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3214 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3215 the Microsoft problem in a different way, by altering ../nt/config.nt.
3217 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3232 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3233 by lisp.h. This completes removal of setjmp.h inclusion
3234 erroneously announced in the previous commit. (Bug#12446)
3236 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3239 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3240 not defined as a macro. The latter happens on MS-Windows.
3243 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3245 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3246 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3247 Some instances of '#include <setjmp.h>' removed, if the
3248 only reason for the instance was because "lisp.h" was included.
3249 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3250 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3251 and _longjmp with the new symbols. Emacs already uses _setjmp if
3252 available, so this change affects only POSIXish hosts that have
3253 sigsetjmp but not _setjmp, such as some versions of Solaris and
3254 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3255 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3256 (png_load_body) [HAVE_PNG]:
3257 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3258 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3259 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3260 since PNG requires jmp_buf. This is the only exception to the
3261 general rule that we now use sys_setjmp and sys_longjmp.
3262 This exception is OK since this code does not change the signal
3263 mask or longjmp out of a signal handler.
3265 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3267 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3268 Include "syssignal.h", for 'main_thread'.
3270 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3272 Avoid out-of-range marker position (Bug#12426).
3273 * insdel.c (replace_range, replace_range_2):
3274 Adjust markers before overlays, as suggested by comments.
3275 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3276 Remove redundant check before calling offset_intervals.
3278 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3280 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3281 current buffer (Bug#12387).
3283 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3285 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3287 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3289 Use a more backwards-compatible timer format (Bug#12430).
3290 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3291 vector element, not from the 4th, since PSECS is now at the end.
3292 (Fcurrent_idle_time): Doc fix.
3294 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3296 Function to mark objects and remove killed buffers at once.
3297 * alloc.c (discard_killed_buffers): Rename to ...
3298 (mark_discard_killed buffers) ... new name. Add marking
3299 of remaining objects. Fix comment. Adjust users.
3300 (mark_object): Do not touch frame buffer lists here.
3301 * frame.c (delete_frame): Reset frame buffer lists here.
3303 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3305 Better workaround for GNOME bug when --enable-gcc-warnings.
3306 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3307 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3308 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3310 Simplify SIGIO usage (Bug#12408).
3311 The code that dealt with SIGIO was crufty and confusing, e.g., it
3312 played tricks like "#undef SIGIO" but these tricks were not used
3313 consistently. Simplify mostly by not #undeffing standard symbols,
3314 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3315 or not as we please) rather than "defined SIGIO" (standard symbol
3316 that we probably shouldn't #undef).
3317 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3318 Modules that need it can include it.
3319 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3320 * dispextern.h (ignore_sigio): New decl.
3321 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3322 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3323 * emacs.c (shut_down_emacs):
3324 * keyboard.c (kbd_buffer_store_event_hold):
3325 Use ignore_sigio rather than invoking 'signal' directly.
3326 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3328 (FIONREAD, SIGIO): Do not #undef.
3329 (tty_read_avail_input): Use #error rather than a syntax error.
3330 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3331 for I_PIPE, used by SETUP_SLAVE_PTY.
3332 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3333 * sysdep.c (croak): Remove; no longer needed. This bit of
3334 temporary code, with Fred N. Fish's comment that it's temporary,
3335 has been in Emacs since at least 1992!
3336 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3337 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3338 * syssignal.h (croak): Remove decl.
3339 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3340 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3341 now that we're termios-only.
3342 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3343 * term.c (dissociate_if_controlling_tty): Use #error rather than
3346 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3347 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3348 to work around GNOME bug 683906.
3349 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3350 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3351 This works around GCC bug 54561.
3353 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3355 More fixes for 'volatile' and setjmp/longjmp.
3356 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3357 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3358 (png_load_body) [HAVE_PNG]:
3359 (jpeg_load_body) [HAVE_JPEG]:
3360 New function, with most of the old parent function's body.
3361 (png_load) [HAVE_PNG]:
3362 (jpeg_load) [HAVE_JPEG]:
3363 Invoke the new function, to avoid longjmp munging our locals.
3364 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3365 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3366 longjmp is passed 2, as the C standard doesn't guarantee this.
3367 Instead, store the failure code into mgr->failure_code.
3369 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3371 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3372 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3373 (syms_of_keyboard): Remove support for unread-command-char.
3375 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3377 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3378 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3379 violation. (Bug#12426)
3381 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3383 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3385 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3387 * eval.c: Add `inhibit-debugger'.
3388 (Qinhibit_debugger): New symbol.
3389 (call_debugger): Bind it instead of Qdebug_on_error.
3390 (maybe_call_debugger): Test Vinhibit_debugger.
3391 (syms_of_eval): Define inhibit-debugger.
3392 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3393 (syms_of_xdisp): Remove inhibit-debug-on-message.
3395 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3397 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3398 If a nonvolatile local variable is written before a _longjmp to
3399 the frame containing the variable, and is read after the _longjmp,
3400 the value read is indeterminate. Some local variables of type
3401 'struct handler' and 'struct catchtag' are used in this way, so
3402 mark each of their slots as volatile if the slot can be set before
3403 _longjmp and read afterwards.
3404 * lisp.h (struct handler): var and chosen_clause are now volatile.
3405 (struct catchtag): val, next, and pdlcount are now volatile.
3407 * bidi.c (bidi_push_it, bidi_pop_it):
3408 * fns.c (copy_hash_table):
3409 * image.c (define_image_type):
3410 * keyboard.c (kbd_buffer_store_event_hold):
3411 * process.c (Fprocess_send_eof):
3412 * xfaces.c (x_create_gc) [HAVE_NS]:
3413 * xgselect.c (xg_select):
3414 Prefer assignment to memcpy when either will do.
3416 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3417 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3418 time an item is removed. No need to mark this function 'inline';
3419 the compiler knows better than we do.
3421 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3423 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3424 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3425 to change_frame_size (Bug#12388).
3426 (windowDidResize:): Pass YES to updateFrameSize.
3428 * nsterm.h: Add delay parameter to updateFrameSize.
3430 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3432 Discard killed buffers from deleted window and frame objects.
3433 This reduces an amount of references to killed buffers and
3434 helps GC to reclaim them faster.
3435 * alloc.c (discard_killed_buffers): New function.
3436 (mark_object): Use it for deleted windows and frames.
3437 (mark_object): If symbol's value is set up for a killed buffer
3438 or deleted frame, restore its global binding.
3439 * data.c (swap_in_global_binding): Add GC notice.
3440 (swap_in_symval_forwarding): Use convenient set_blv_where.
3441 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3442 * window.h: ... to here.
3444 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3446 Convenient macro to check whether the buffer is live.
3447 * buffer.h (BUFFER_LIVE_P): New macro.
3448 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3449 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3451 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3453 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3454 composition cases (Bug#12364).
3456 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3457 overhang of succeeding glyphs overlapping box cursor.
3459 * w32term.c (x_draw_glyph_string): Likewise.
3461 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3463 Simplify, document, and port floating-point (Bug#12381).
3464 The porting part of this patch fixes bugs on non-IEEE platforms
3465 with frexp, ldexp, logb.
3466 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3468 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3469 support, by removing commented-out code and briefly listing the
3470 C89 functions excluded. The commented-out stuff was confusing
3471 maintenance, e.g., we thought we needed cbrt but it was commented out.
3472 (logb): Remove decl; no longer needed.
3473 (isfinite): New macro, if not already supplied.
3474 (isnan): Don't replace any existing macro.
3475 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3476 are present on all C89 platforms.
3477 (Ffrexp): Do not special-case zero, as frexp does the right thing
3479 (Flogb): Do not use logb, as it doesn't have the desired meaning
3480 on hosts that use non-base-2 floating point. Instead, stick with
3481 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3482 frexp, to avoid getting an unspecified result.
3484 * xdisp.c (Qinhibit_debug_on_message): Now static.
3486 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3488 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3489 NSBezierPath (Bug#12131).
3491 2012-09-10 Chong Yidong <cyd@gnu.org>
3493 * fns.c (Fdelq, Fdelete): Doc fix.
3495 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3497 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3498 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3500 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3502 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3503 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3506 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3508 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3509 left fringe if the window has a left margin. This avoids leaving
3510 traces of the cursor because its leftmost pixel is not drawn over.
3512 * dispnew.c (update_window_line): When the left margin area of a
3513 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3514 that screen line. (Bug#12277)
3516 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3518 Assume C89 or later for math functions (Bug#12381).
3519 This simplifies the code, and makes it a bit smaller and faster,
3520 and (most important) makes it easier to clean up signal handling
3521 since we can stop worring about floating-point exceptions in
3522 library code. That was a problem before C89, but the problem
3523 went away many years ago on all practical Emacs targets.
3524 * data.c, image.c, lread.c, print.c:
3525 Don't include <math.h>; no longer needed.
3526 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3527 might be autoconfigured, as that never happens.
3529 * doprnt.c (DBL_MAX_10_EXP):
3530 * print.c (DBL_DIG):
3531 Remove. C89 or later always defines these.
3532 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3533 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3534 (arith_error, domain_error, domain_error2):
3535 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3536 no longer needed -- we simply return what C returns. All uses removed.
3537 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3539 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3540 Remove. All uses expanded, as these macros are no longer used
3541 more than once and are now more trouble than they're worth.
3542 (Ftan): Use tan, not sin / cos.
3543 (Flogb): Assume C89 frexp.
3544 (fmod_float): Assume C89 fmod.
3545 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3546 (init_floatfns): Remove. All uses removed.
3548 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3550 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3551 compositeToPoint for OSX < 10.6 (Bug#12390).
3553 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3555 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3556 This produces more-accurate results.
3558 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3560 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3561 changes (Bug#12088).
3563 2012-09-08 Chong Yidong <cyd@gnu.org>
3565 * syntax.c (Fstring_to_syntax): Doc fix.
3567 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3569 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3570 in the internal border.
3571 (x_set_window_size): Remove static variables and their usage.
3572 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3573 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3574 Remove fringe/internal border adjustment (Bug#11052).
3575 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3576 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3577 (ns_fix_rect_ibw): Remove.
3578 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3579 (ns_dumpglyphs_box_or_relief): Ditto.
3580 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3582 (ns_dumpglyphs_image): Ditto.
3583 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3585 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3586 their usage. Add fringe_extended_p and its use as in other terms.
3587 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3588 scroll bar was removed.
3589 (updateFrameSize): New function.
3590 (windowDidResize): Move code to updateFrameSize and call it.
3592 * nsterm.h (EmacsView): Add updateFrameSize.
3594 2012-09-07 Chong Yidong <cyd@gnu.org>
3596 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3598 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3600 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3602 More signal-handler cleanup (Bug#12327).
3603 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3604 Problem introduced when merging patches. Noted by Eli Zaretskii in
3605 <http://bugs.gnu.org/12327#67>.
3606 * floatfns.c: Comment fix.
3607 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3608 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3609 and anyway the declaration is harmless even if SIGDANGER is not defined.
3610 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3611 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3612 source files not surprisingly expected syssignal.h to define, or
3613 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3614 Include <sys/ioctl.h>, for FIONREAD.
3615 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3616 This eliminates a problem whereby other files mysteriously had
3617 to include "syssignal.h" before including "systty.h" if they
3618 wanted to use "#ifdef SIGIO".
3620 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3622 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3624 * w32.c (sigemptyset): Empty the set.
3625 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3627 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3629 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3631 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3632 (mark_object): Likewise for frame objects.
3634 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3636 * syssignal.h (handle_on_main_thread): Always declare,
3637 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3638 This ports to platforms without HAVE_PTHREAD.
3640 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3642 Signal-handler cleanup (Bug#12327).
3643 Emacs's signal handlers were written in the old 4.2BSD style with
3644 sigblock and sigmask and so forth, and this led to some
3645 inefficiencies and confusion. Rewrite these to use
3646 pthread_sigmask etc. without copying signal sets around. Also,
3647 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3648 'signal', and instead use functions that do not attempt to take
3649 over the system name space. This patch causes Emacs's text
3650 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3651 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3652 Do not include <signal.h> or "syssignal.h", as these
3653 modules do not use signals.
3654 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3655 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3656 Do not include <signal.h>, as "syssignal.h" does that for us now.
3657 * atimer.c (sigmask_atimers): New function.
3658 (block_atimers, unblock_atimers): New functions,
3659 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3661 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3662 no longer needed here.
3663 * emacs.c (main): Inspect existing signal handler with sigaction,
3664 so that there's no need to block and unblock SIGHUP.
3665 * sysdep.c (struct save_signal): New member 'action', replacing
3666 old member 'handler'.
3667 (save_signal_handlers, restore_signal_handlers):
3668 Use sigaction instead of 'signal' to save and restore.
3669 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3670 New function. All users of 'signal' modified to use set_sighandler
3671 if they're writeonly, and to use sys_signal if they're read+write.
3672 (emacs_sigaction_init, forwarded_signal): New functions.
3673 (sys_signal): Remove. All uses replaced by calls to sigaction
3674 and emacs_sigaction_init, or by direct calls to 'signal'.
3675 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3676 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3677 all uses replaced by pthread_sigmask etc. calls.
3678 * syssignal.h: Include <signal.h>.
3679 (emacs_sigaction_init, forwarded_signal): New decls.
3680 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3681 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3682 (sigmask, sys_sigmask): Remove; no longer needed.
3683 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3684 (sigblock, sigunblock, sigfree):
3685 (sigsetmask) [!defined sigsetmask]:
3686 Remove. All uses replaced by pthread_sigmask.
3687 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3688 no longer need to be replaced, and its typical old uses
3689 are now done via emacs_sigaction_init and sigaction.
3690 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3691 (sys_sigdel): Remove; unused.
3692 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3694 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3696 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3697 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3699 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3701 Explicitly mark buffer_defaults and buffer_local_symbols.
3702 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3703 mark_local_symbols here.
3704 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3705 since special buffers aren't marked here any more.
3706 (allocate_buffer): Chain new buffer with all_buffers here...
3707 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3709 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3710 (syms_of_buffer): Remove staticpro of the above.
3711 (init_buffer_once): Set names for buffer_defaults and
3712 buffer_local_symbols.
3714 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3716 Use bool for booleans in font-related modules.
3717 * font.c (font_intern_prop, font_style_to_value)
3718 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3719 (generate_otf_features, font_check_otf_features, font_check_otf)
3720 (font_match_p, font_list_entities, font_at):
3721 * fontset.c (fontset_id_valid_p, reorder_font_vector
3722 (fontset_find_font, Fset_fontset_font)
3723 (face_suitable_for_char_p) [0]:
3724 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3725 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3726 (m17n_flt_initialized, ftfont_shape_by_flt):
3727 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3728 * nsfont.m (nsfont_draw):
3729 * w32font.c (w32font_draw):
3730 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3731 Use bool for booleans.
3732 * font.h: Adjust to above API changes.
3733 (struct font, struct font_driver, struct font_driver_list):
3734 Use bool for booleans.
3735 (struct font): Remove useless member encoding_type.
3737 * fontset.c, xftfont.c: Omit unnecessary static decls.
3739 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3741 * alloc.c (mark_object): Revert window marking code
3742 since it's unsafe for the Fset_window_configuration.
3744 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3746 Fix race conditions with signal handlers and errno (Bug#12327).
3747 Be more systematic about preserving errno whenever a signal
3748 handler returns, even if it's not in the main thread. Do this by
3749 renaming signal handlers to distinguish between signal delivery
3750 and signal handling. All uses changed.
3751 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3752 * data.c (deliver_arith_signal): Rename from arith_error.
3753 * dispnew.c (deliver_window_change_signal): Rename from
3754 window_change_signal.
3755 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3756 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3757 * keyboard.c (deliver_input_available_signal): Rename from
3758 input_available_signal.
3759 (deliver_user_signal): Rename from handle_user_signal.
3760 (deliver_interrupt_signal): Rename from interrupt_signal.
3761 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3762 (deliver_child_signal): Rename from sigchld_handler.
3763 * atimer.c (handle_alarm_signal):
3764 * data.c (handle_arith_signal):
3765 * dispnew.c (handle_window_change_signal):
3766 * emacs.c (handle_fatal_signal, handle_danger_signal):
3767 * keyboard.c (handle_input_available_signal):
3768 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3769 * process.c (handle_pipe_signal, handle_child_signal):
3770 New functions, with the actual signal-handling code taken from the
3771 original respective signal handlers, sans the sporadic attempts to
3772 preserve errno, since that's now done by handle_on_main_thread.
3773 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3774 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3775 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3777 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3778 Move initialization of main_thread to sysdep.c's init_signals.
3779 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3780 our usage, and simplifies the mainline code.
3781 (record_child_status_change): New static function, as a helper
3782 for handle_child_signal, and with most of the old child handler's
3784 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3785 (handle_child_signal): Use the above.
3786 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3787 Moved here from emacs.c.
3788 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3789 code moved here from emacs.c's main function.
3790 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3791 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3792 This lets callers save and restore errno properly.
3794 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3796 Remove redundant or unused things here and there.
3797 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3798 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3799 * editfns.c (Fcompare_buffer_substrings): Likewise.
3800 * frame.h (struct terminal, struct font_driver_list):
3801 Remove redundant declarations.
3802 * window.h (Qleft, Qright): Likewise.
3804 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3806 Do not mark objects from deleted buffers, windows and frames.
3807 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3808 (mark_object): Likewise for windows and frames.
3810 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3812 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3813 buffer_defaults and buffer_local_symbols as valid objects.
3814 Return special value to denote them.
3816 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3818 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3819 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3820 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3821 (file_name_absolute_p, Fsubstitute_in_file_name):
3822 (check_executable, check_writable, Ffile_accessible_directory_p)
3823 (Fset_file_selinux_context, Fdefault_file_modes)
3824 (Finsert_file_contents, choose_write_coding_system)
3825 (Fwrite_region, build_annotations, a_write, e_write)
3827 * filelock.c (boot_time_initialized, get_boot_time)
3828 (get_boot_time_1, lock_file_1, within_one_second):
3829 * floatfns.c (in_float):
3830 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3831 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3832 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3833 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3834 * window.c (compare_window_configurations):
3835 Use bool for booleans.
3836 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3837 (Fdefault_file_modes): Now mode_t, not int, for modes.
3838 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3839 (internal_delete_file): Now returns void, not a (boolean) int,
3840 since nobody was looking at the return value.
3841 * lisp.h, window.h: Adjust to above API changes.
3843 * xdisp.c (set_message): Simplify and reindent last change.
3845 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3847 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3849 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3851 * eval.c (call_debugger): Make the function non-static so that we
3852 can call it from set_message.
3854 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3855 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3857 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3859 Give more-useful info on a fatal error (Bug#12328).
3860 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3861 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3862 of doing the work ourselves.
3863 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3864 do most of the work.
3865 (fatal_error_backtrace): New function, taken from the guts
3866 of the old fatal_error_signal, but with a new option to output
3868 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3869 info about the signal than just its number.
3870 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3871 * sysdep.c: Include <execinfo.h>
3872 (emacs_backtrace): New function, taken partly from the previous
3873 code of the 'die' function.
3874 (emacs_abort): Call fatal_error_backtrace rather than abort.
3876 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3878 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3879 eager (load-time) macro-expansion.
3880 * lisp.mk (lisp): Add macroexp.
3882 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3884 Simplify redefinition of 'abort' (Bug#12316).
3885 Do not try to redefine the 'abort' function. Instead, redo
3886 the code so that it calls 'emacs_abort' rather than 'abort'.
3887 This removes the need for the NO_ABORT configure-time macro
3888 and makes it easier to change the abort code to do a backtrace.
3889 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3890 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3891 Remove; sysdep.c's emacs_abort now takes its place.
3892 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3893 'abort' changed to use 'emacs_abort'.
3894 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3895 (abort) [!defined abort]: Rename to ...
3896 (emacs_abort): ... new name.
3897 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3898 the place of the old 'abort' in emacs.c.
3899 * w32.c, w32fns.c (abort): Do not #undef.
3900 * w32.c (emacs_abort): Rename from w32_abort.
3902 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3904 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3905 offsets[j].dv, since the y axis of the screen coordinates points
3906 down, while the y axis of the font definition coordinates points
3907 up. This fixes display of Arabic diacritics such as KASRA and
3908 KASRATAN. (Bug#11860)
3910 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3912 Be more systematic about _setjmp vs setjmp.
3913 * alloc.c (test_setjmp, mark_stack):
3914 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3915 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3916 (png_load, my_error_exit, jpeg_load):
3917 * process.c (send_process_trap, send_process):
3918 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3919 The underscored versions are up to 30x faster on some hosts.
3920 Formerly, the code used setjmp+longjmp sometimes and
3921 _setjmp+_longjmp at other times, with no particular reason to
3922 prefer setjmp+longjmp.
3924 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3926 Fix minor problem found by static checking.
3927 * buffer.c (Fdelete_all_overlays): Return nil.
3929 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3931 * buffer.c (Fdelete_all_overlays): New function.
3933 2012-09-03 Chong Yidong <cyd@gnu.org>
3935 * gtkutil.c: Add extern decl for Qxft.
3937 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3939 * emacs.c, eval.c: Use bool for boolean.
3940 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3941 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3942 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
3943 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
3944 (main, decode_env_path, Fdaemon_initialized):

3946 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
3947 (maybe_call_debugger, Fbacktrace):
3948 * process.c (read_process_output, exec_sentinel):
3949 Use bool for booleans.
3950 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3951 All callers changed.
3952 * eval.c (interactive_p): Omit always-true boolean argument
3953 EXCLUDE_SUBRS_P. All callers changed.
3954 * dispextern.h, lisp.h: Reflect above API changes.
3955 * firstfile.c (dummy): Use the address of 'main', whose signature
3956 won't change, instead of the address of 'initialize', whose
3957 signature just changed from int to bool.
3958 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3959 * msdos.c (fatal_error_in_progress): ... from here.
3960 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3962 (redisplay_internal, unwind_redisplay): Simply clear
3963 REDISPLAYING_P when unwinding, instead of saving its previous,
3964 always-false value and then restoring it.
3966 Clean up some extern decls.
3967 Mostly, this hoists extern decls out of .c files and into .h files.
3968 That way, we're more likely to catch errors if the interfaces change.
3969 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3970 declare xg_mark_data.
3971 * dispextern.h (x_frame_parm_handlers):
3973 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3974 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3975 (Qultra_bold, Qoblique, Qitalic):
3976 Move extern decl here from .c file.
3977 * alloc.c (xg_mark_data) [USE_GTK]:
3979 * eval.c (Qlexical_binding):
3980 * fns.c (time) [!HAVE_UNISTD_H]:

3986 * process.c (QCfamily, QCfilter):
3987 * widget.c (free_frame_faces):
3988 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3989 * xfont.c (x_clear_errors):
3990 * xterm.c (x_frame_parm_handlers):
3991 Remove now-redundant extern decls.
3992 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3993 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3995 * xfaces.c: Remove unnecessary static decls.
3996 * xterm.c (updating_frame): Remove decl of nonexistent object.
3998 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3999 when building globals.h, as the objects that are not built on
4000 this host are not needed to compile C files on this host.
4002 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4004 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4006 * frame.h: Add missing prototype for x_wm_set_size_hint.
4008 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4012 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4013 (Fsubstitute_command_keys):

4018 (make_buffer_string, make_buffer_string_both)
4019 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

4031 (set_intervals_multibyte_1, set_intervals_multibyte):
4032 * keyboard.c (decode_timer):
4033 Use bool for boolean.
4034 * intervals.h, lisp.h, systime.h: Reflect above API changes.
4035 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
4037 2012-09-02 Chong Yidong <cyd@gnu.org>
4039 * keymap.c (push_key_description): Print M-TAB as C-M-i
4042 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4044 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4045 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
4046 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

4050 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4052 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4054 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4055 more than one grapheme cluster passed to the shaper: compute the
4056 offset adjustment values separately for each cluster. (Bug#11860)
4058 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4059 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4060 about implicit conversions from integer to pointer.
4062 2012-09-01 Daniel Colascione <dancol@dancol.org>
4064 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4065 system used too early.
4067 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4069 Better seed support for (random).
4070 * emacs.c (main): Call init_random.
4071 * fns.c (Frandom): Set the seed from a string argument, if given.
4072 Remove long-obsolete Gentzel cruft.
4073 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
4074 (init_random): New function.
4076 2012-09-01 Daniel Colascione <dancol@dancol.org>
4078 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.

4352 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4353 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4354 not a boolean 'int', since callers never look at the return value.

4377 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4379 Special MEM_TYPE_SPARE to denote reserved memory.
4380 * alloc.c (enum mem_type): New memory type.
4381 (refill_memory_reserve): Use new type for spare memory.

4411 (map_sub_char_table):
4412 Use bool for boolean.

4417 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4418 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4419 are all boolean, so make them single-bit bitfields.
4421 * lisp.h (ASET): Remove attempt to detect side effects.
4422 It was meant to be temporary and it often doesn't work,
4423 because when IDX has side effects the behavior of IDX==IDX
4424 is undefined. See Stefan Monnier in
4425 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4427 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

4430 (FUNCTIONP): Use it.
4431 * eval.c (Ffunctionp): Use it.
4433 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4435 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4436 as that's faster and simpler than static storage. Don't bother
4437 with the g_main_context_query overhead if g_main_context_pending
4438 says no events are pending.
4439 (gfds, gfds_size): Remove these static vars.
4440 (xgselect_initialize): Remove; no longer needed.
4441 All uses and decls removed.
4443 * emacs.c (fatal_error_signal_hook): Remove.
4444 All uses removed. This leftover from old code was always 0.

4471 Use bool for booleans, instead of int.
4472 * lisp.h, process.h: Adjust prototypes to match above changes.
4473 * callint.c (Fcall_interactively): Don't assume the mark's
4474 offset fits in 'int'.

4487 Use bool for booleans, instead of int.
4488 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4489 since the 1-or-0 return value is always ignored anyway.
4490 (mmap_initialized_p):
4491 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4492 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4494 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4496 * bidi.c: Use bool for boolean.
4497 This is a bit more readable, and makes the text segment of bidi.o
4498 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4499 Presumably it's faster too.

4533 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4535 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4536 Otherwise, the compiler complains about (A?B:C) where B is void
4537 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4538 (fontset_add): Return void, for FONTSET_ADD.
4540 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4542 * alloc.c: Use bool for booleans.
4543 (gc_in_progress, abort_on_gc)
4544 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4545 (dont_register_blocks) [GC_MALLOC_CHECK]:
4546 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4547 (check_string_bytes, make_specified_string, memory_full)
4548 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4549 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4550 (mark_stack, valid_pointer_p, make_pure_string)
4551 (Fgarbage_collect, survives_gc_p, gc_sweep):
4552 Use bool for booleans, instead of int.
4553 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4554 Remove unused local.
4555 * alloc.c (PURE_POINTER_P):
4556 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4557 * editfns.c (Fformat):
4558 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4560 * fns.c (sweep_weak_table):
4561 * lisp.h (suppress_checking, push_message, survives_gc_p)
4562 (make_pure_string, gc_in_progress, abort_on_gc):
4563 * lread.c (readchar, read1):
4564 * print.c (Fprin1_to_string):
4565 * xdisp.c (push_message):
4566 Use bool for booleans affected directly or indirectly by
4569 Make recently-introduced setters macros.
4570 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4571 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4572 (set_fontset_default, set_fontset_fallback): Rename from their
4573 upper-case counterparts, and make them functions rather than macros.
4574 This is more consistent with the other recently-introduced setters.
4575 These don't need to be inline, since they're local.
4577 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4579 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4580 the loop (Bug#12247).
4582 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4584 * lisp.h (vcopy): Use memcpy rather than our own loop.
4585 This fixes a performance regression introduced by the recent
4586 addition of vcopy. This means 'vcopy' will need to be modified
4587 for a copying collector, but that's OK. Also, tighten the
4588 checking in the assertion.
4590 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4592 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4593 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4594 non-base glyph for the width of the base character, according to
4595 what x_draw_composite_glyph_string_foreground expects.
4596 Generate WADJUST value according to composition_gstring_width's
4597 expectations, to produce correct width of the composed character.
4598 Reverse the sign of the DU offset produced by ScriptPlace.
4600 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4602 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4604 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4606 Avoid direct writes to contents member of struct Lisp_Vector.
4607 * lisp.h (vcopy): New function to copy data into vector.
4608 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4609 * fns.c (Ffillarray): Use ASET.
4610 * keyboard.c (timer_check_2): Use AREF and ASET.
4611 (append_tool_bar_item, Frecent_keys): Use vcopy.
4612 * lread.c (read_vector): Use ASET.
4613 * msdos.c (Frecent_doskeys): Use vcopy.
4614 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4615 (Finternal_merge_in_global_face): Use ASET and vcopy.
4616 * xfont.c (xfont_list_pattern): Likewise.
4618 2012-08-21 Martin Rudalics <rudalics@gmx.at>
4620 * window.c (Fwindow_point): For the selected window always return
4621 the position of its buffer's point.
4622 (Fset_window_point): For the selected window always go in its
4623 buffer to the specified position.
4625 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4627 Setter macros for fontsets.
4628 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4629 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4630 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4633 2012-08-20 Glenn Morris <rgm@gnu.org>
4635 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4636 Don't assume that `ln -f' works.
4638 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4640 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4641 and later about non-assignments with no effect. See discussion at
4642 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4645 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4647 Inline setter functions for Lisp_Objects slots of struct specbinding.
4648 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
4651 2012-08-20 Martin Rudalics <rudalics@gmx.at>
4653 * window.c (select_window): Always make selected window's buffer
4656 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4658 Use AREF and ASET for docstrings of category tables.
4659 * category.h (CATEGORY_DOCSTRING): Use AREF.
4660 (SET_CATEGORY_DOCSTRING): Use ASET.
4661 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
4663 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4665 Inline setter functions for hash table members.
4666 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4667 (set_hash_hash, set_hash_index): Rename with _slot suffix.
4668 (set_hash_key_and_value, set_hash_index, set_hash_next)
4669 (set_hash_hash): New functions.
4670 * charset.c, fns.c: Adjust users.
4672 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4674 Inline getter and setter functions for per-buffer values.
4675 * buffer.h (per_buffer_default, set_per_buffer_default)
4676 (per_buffer_value, set_per_buffer_value): New functions.
4677 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
4678 * buffer.c, data.c: Adjust users.
4680 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
4682 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
4684 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4686 Rely on <config.h> + <unistd.h> to declare 'environ',
4687 as gnulib does this if the system doesn't.
4688 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4689 Remove declaration. MS-Windows declares it on stdlib.h which is
4690 included by conf_post.h.
4691 * emacs.c (environ) [DOUG_LEA_MALLOC]:
4692 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
4693 * vm-limit.c: Include <unistd.h>, for 'environ'.
4695 * unexaix.c, unexcoff.c: Include "mem-limits.h".
4696 (start_of_data): Remove decl; mem-limits.h provides it.
4698 * xdisp.c (handle_invisible_prop): Make it a bit faster
4699 and avoid a gcc -Wmaybe-uninitialized diagnostic.
4701 2012-08-19 Chong Yidong <cyd@gnu.org>
4703 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
4706 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
4708 * .gdbinit: Use call instead of set when calling a function in the
4711 * data.c (set_internal): Don't use set_blv_found.
4712 (Fkill_local_variable): Likewise.
4714 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4716 * nsfont.m (ns_ascii_average_width): Ensure the string
4717 ascii_printable is initialized with a null-terminated character
4718 array. Otherwise, it can contain undesired extra characters.
4720 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4722 port new setting code to Sun C 5.8 2005/10/13
4723 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4724 Return void, not Lisp_Object. Otherwise, the compiler
4725 complains about (A?B:C) where B is void and C is Lisp_Object
4726 when compiling CHAR_TABLE_SET, due to the recent change to
4727 the API of sub_char_table_set_contents.
4729 2012-08-18 Chong Yidong <cyd@gnu.org>
4731 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
4732 for the string case (Bug#3874).

4887 The old version was confusing because it used the same name
4888 'parent' for two different things.
4890 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
4892 Functions to get and set Lisp_Object fields of buffer-local variables.

4901 font spec, make the font's attributes take precedence over
4902 directly-specified attributes.
4903 (merge_face_ref): Recognize :font.
4905 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
4907 Do not use memcpy for copying intervals.

4930 Use ASCII tests for character types.
4931 * category.c, dispnew.c, doprnt.c, editfns.c, syntax.c, term.c:
4933 Don't include <ctype.h>; was not needed.
4934 * charset.c, doc.c, fileio.c, font.c, frame.c, gtkutil.c, image.c:
4935 * sysdep.c, xfaces.c:
4936 Include <c-ctype.h> instead of <ctype.h>.

4951 * xfaces.c (hash_string_case_insensitive):
4952 Use C-locale tests instead of locale-specific tests for character
4953 types, since we want the ASCII interpretation here, not the
4954 interpretation suitable for whatever happens to be the current locale.

5559 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5560 * w32.c (init_environment): Change the default values of many
5561 environment variables in dflt_envvars[] to NULL, to avoid pushing
5562 them into environment when they were not already defined.
5563 Remove the code that deletes site-lisp subdirectories from the default
5564 value of EMACSLOADPATH, as it is no longer needed.
5565 (check_windows_init_file): Now external, not static.
5566 Use Vload_path as is, without adding anything, as this function is now
5567 called when Vload_path is already set up.
5569 * w32.h (check_windows_init_file): Add prototype.
5571 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

5578 installation tree, as appropriate.
5580 * callproc.c (init_callproc_1): Call decode_env_path instead of
5581 doing its equivalent by hand.

5583 the code that sets Vexec_path run on MS-Windows.
5585 * lread.c (init_lread): Add comments to #ifdef's.
5587 * msdos.c (dos_set_window_size, IT_update_begin)

5599 Remove unnecessary casts involving pointers.
5600 These casts are no longer needed now that we assume C89 or later,

5614 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5615 Remove unnecessary pointer casts.
5616 * alloc.c (record_xmalloc): New function.
5617 * lisp.h (record_xmalloc): New decl.
5618 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5619 more like a function. This is because the pointer cast is not
5620 needed. All uses changed.
5621 * print.c (print_string, print_error_message): Avoid length recalc.
5623 Improve fix for macroexp crash with debugging (Bug#12118).
5624 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5625 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5626 not supposed to be invoked from the garbage collector.
5627 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
5628 (gc_aset): New function, which is like ASET but can be
5629 used in the garbage collector.
5630 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

5645 headers (most versions of MinGW w32api don't).
5646 (get_security_info, create_symbolic_link)
5647 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

5658 with addition of handling of symlinks and support for 'lstat'.
5659 If possible, get file's attributes and security information by
5660 handle, not by name. Produce S_IFLNK bit for symlinks, when
5661 called from 'lstat'.
5662 (stat, lstat): New functions, call 'stat_worker'.
5663 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5664 symlinks when the underlying filesystem supports them.
5666 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5668 Fix macroexp crash on Windows with debugging (Bug#12118).
5669 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5670 checking subscripts; problem introduced with the recent
5671 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5672 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5673 since it's used in non-static inline functions now.
5675 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5676 Don't assume buffer size fits in 'int'. Remove unused local.

5694 * character.c (CHARACTER_INLINE):
5695 * charset.c (CHARSET_INLINE):
5696 * composite.c (COMPOSITE_INLINE):
5697 * dispnew.c (DISPEXTERN_INLINE):
5698 * sysdep.c (SYSTIME_INLINE):
5699 Define to EXTERN_INLINE, so that the corresponding functions
5700 are compiled into code.
5701 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5702 (INLINE_HEADER_END): New macros.
5703 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5723 hard-coding the path separator.
5725 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5727 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5728 This how ASET and AREF are supposed to work, and makes
5729 it easier to think about future improvements. See
5730 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5731 * charset.h (set_charset_attr): New function.

6221 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6222 emacs.c, as this is a more-suitable home. Had this been done earlier
6223 the fix for 12036 would have avoided some of the problems noted in
6224 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6225 would have been more obvious.
6226 * emacs.c: Do not include <verify.h>; no longer needed.

6235 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6236 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6237 not be usable in #if. This simplifies things.
6239 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6241 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6243 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

6246 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6247 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6248 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6249 Adjust to changes in lisp.h and emacs.c, by using

6252 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

6254 instead of gdb_valbits.
6255 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6256 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6257 instead of gdb_array_mark_flag.
6258 (xboolvector): Get size from $->size, not $->header.size.
6259 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6260 (xreload, hook-run, hookpost-run): Remove.
6261 * emacs.c: Include <verify.h>.
6262 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6263 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6265 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6266 (gdb_USE_LSB_TAG): New enum constants.
6267 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6268 Also define these as enum constants, so they're visible to GDB.

6270 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

6275 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is

7154 (menu_separator_name_p):

7159 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7160 Prefer snprintf to strncpy.
7161 * nsterm.m (ns_term_init):
7162 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7163 * nsterm.m (ns_term_init):
7164 Avoid the need for strncpy, by using build_string or
7165 make_unibyte_string directly. Use dtoastr, not snprintf.
7166 * process.c (Fmake_network_process): Diagnose service names that
7167 are too long, rather than silently truncating them or creating
7168 non-null-terminated names.

7198 Optimize pure C strings initialization.
7199 * lisp.h (make_pure_string): Fix prototype.
7200 (build_pure_c_string): New function, defined as static inline. This
7201 provides a better opportunity to optimize away calls to strlen when
7202 the function is called with compile-time constant argument.
7203 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7204 argument, adjust users accordingly. Use build_pure_c_string where
7206 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7207 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7208 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7210 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7212 Avoid calls to strlen in miscellaneous functions.
7213 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7214 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7215 * lread.c (openp): Likewise.

7219 Avoid calls to strlen in path processing functions.
7220 * fileio.c (file_name_as_directory): Add comment. Change to add
7221 srclen argument and return the length of result. Adjust users

7224 swap 1st and 2nd arguments to obey the common convention.
7225 Adjust users accordingly.
7226 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7228 2012-07-10 Glenn Morris <rgm@gnu.org>

7235 * s/gnu.h (DATA_START): Move definitions to configure.
7237 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7238 We include usg5-4-common.h, which defines them both.
7240 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7241 O_RDONLY already includes it).
7243 Stop ns builds setting the EMACSLOADPATH environment variable.
7244 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7245 Now it does not set EMACSLOADPATH, just returns the load-path string.
7246 * nsterm.h: Update accordingly.
7247 * lread.c [HAVE_NS]: Include nsterm.h.
7248 (init_lread) [HAVE_NS]: Use ns_load_path.

7251 2012-07-09 Glenn Morris <rgm@gnu.org>
7253 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7254 since the included bsd-common.h does so.
7256 Stop ns builds setting the EMACSPATH environment variable.
7257 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7258 (ns_init_paths): Do not set EMACSPATH.
7259 * nsterm.h (ns_exec_path): Add it.
7260 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7263 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7265 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7267 * process.c (wait_reading_process_output): 'waitchannels' was unset
7268 when read_kbd || !NILP (wait_for_cell); fix this.
7270 Add GCC-style 'const' attribute to functions that can use it.
7271 * character.h (char_resolve_modifier_mask):
7272 * keyboard.h (make_ctrl_char):
7273 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7280 Declare the dummy function with ATTRIBUTE_CONST.
7281 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7282 Add decls with ATTRIBUTE_CONST.
7284 Minor improvements to make_formatted_string.
7285 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7286 where int is good enough, as vsprintf returns an int.
7287 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7289 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7291 Use make_formatted_string to avoid double length calculation.
7292 * lisp.h (make_formatted_string): New prototype.
7293 * alloc.c (make_formatted_string): New function.
7294 * buffer.c (Fgenerate_new_buffer_name): Use it.

7316 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7318 Move marker debugging code under MARKER_DEBUG.
7319 * marker.c (MARKER_DEBUG): Move marker debugging code under
7320 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7321 for bootstrap with --enable-checking (~3x slowdown reported
7322 by Juanma Barranquero <lekktu@gmail.com>).
7323 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7325 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7327 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7328 See <http://bugs.gnu.org/11825#29>.
7330 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7332 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7333 has no font, use the frame's font. (Bug#11813)
7334 (display_line): Add commentary about displaying truncation glyphs
7336 (produce_special_glyphs): Move here from term.c.
7338 * term.c (produce_special_glyphs): Move to xdisp.c.
7340 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7343 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7345 * xdisp.c (display_line): Avoid warning about implicit declaration
7348 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7350 * lisp.h: Remove empty conditional.
7352 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7354 * lread.c (load_path_check): Now static.
7356 Fix some minor --with-ns problems found by static checking.
7357 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7358 (x_set_font) [!HAVE_X_WINDOWS]:
7359 * image.c (xpm_load_image) [HAVE_NS]:
7360 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7361 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7362 Remove unused local.
7363 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7364 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7365 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7366 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7367 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7368 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7369 Fix pointer signedness problem.
7370 * xfaces.c (FRAME_X_FONT_TABLE):
7371 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7373 2012-07-07 Glenn Morris <rgm@gnu.org>
7375 * lread.c (load_path_check): New function, split from init_lread.
7376 (init_lread): Reorganize. Motivation:
7377 If EMACSLOADPATH is set, check/warn about that rather than the
7378 defaults, which we are not going to use. Hence we can remove
7379 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7380 Don't warn if site-lisp directories are missing.
7381 If not installed, start from a blank load-path, since
7382 PATH_LOADSEARCH refers to the eventual installation directories.
7384 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7386 Support truncation and continuation glyphs on GUI frames, when
7387 fringes are disabled. (Bug#11832)
7388 * xdisp.c (init_iterator): Get dimensions of truncation and
7389 continuation glyphs even if on GUI frames.
7390 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7391 or both, are absent.
7392 (start_display, move_it_in_display_line_to): Handle the case of a
7393 GUI frame without a fringe to display continuation or truncation
7395 (insert_left_trunc_glyphs): Support GUI frames: make sure
7396 truncation glyphs overwrite enough glyphs from the current line to
7397 have sufficient space in pixels.
7398 (display_line): Support truncation and continuation glyphs on GUI
7399 frames. If some spare pixels are left on the line after inserting
7400 the truncation glyphs, fill that space with a stretch glyph of a
7401 suitably computed width.
7403 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7404 produce_glyphs, to support GUI sessions.
7406 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7408 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7410 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7412 Do not require float-time's arg to fit in time_t (Bug#11825).
7413 This works better on hosts where time_t is unsigned, and where
7414 float-time is applied to the (negative) difference between two times.
7415 * editfns.c (decode_time_components): Last arg is now double *,
7416 not int *, and means to store all the result as a double, without
7417 worrying about whether the seconds part fits in time_t.
7418 All callers changed.
7419 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7420 All callers changed.
7421 (Ffloat_time): Do not fail merely because the specified time falls
7422 outside of time_t range.
7424 2012-07-07 Glenn Morris <rgm@gnu.org>
7426 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7432 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7433 Update dependencies.
7435 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7437 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7439 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

7441 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7442 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7443 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

7446 * xfont.c (compare_font_names): Redo to omit the need for casts.
7448 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7450 * xfns.c (Fx_change_window_property): Doc fix.
7451 * w32fns.c (Fx_change_window_property): Doc fix.
7453 * w32fns.c (Fx_window_property): Accept the same arguments as the
7454 X Windows version. Doc fix.
7455 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7457 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7458 Eli Zaretskii <eliz@gnu.org>
7460 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7461 Windows-specific code from nt/config.nt moved here.
7462 Obsolete settings removed.
7464 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7466 * process.c: Avoid unnecessary calls to gettime.
7467 (wait_reading_process_output): Don't get the time of day
7468 when gobbling data immediately and not waiting, as there's no need
7469 for it in that case. This removes a FIXME.
7471 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7473 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7474 is defined (Bug#11768).
7476 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7478 Fix marker debugging code.
7479 * marker.c (byte_char_debug_check): Do not perform the check
7480 if buffer is not multibyte.
7481 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7482 Call byte_char_debug_check with correct arguments.
7484 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7486 Compile marker debugging code only if ENABLE_CHECKING is defined.
7487 * marker.c (byte_char_debug_check, count_markers):
7488 Use only if ENABLE_CHECKING is defined.
7489 (byte_debug_flag): Remove.
7490 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7491 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7493 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7495 Avoid code repetition in marker-related functions.
7496 * marker.c (attach_marker): New function.
7497 (Fset_marker, set_marker_restricted, set_marker_both)
7498 (set_marker_restricted_both): Use it.
7499 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7500 Consistently rename charno to charpos.
7501 (marker_position): Add eassert.
7502 (marker_byte_position): Convert to eassert.

7521 * window.c (save_window_save): Likewise.
7523 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7525 Do not use Fdelete_overlay in delete_all_overlays
7526 to avoid redundant calls to unchain_overlay.
7527 * buffer.c (drop_overlay): New function.
7528 (delete_all_overlays, Fdelete_overlay): Use it.
7529 * minibuf.c (get_minibuffer): Fix comment.

7533 Port to OpenBSD 5.1 amd64.
7534 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7535 This is needed for OpenBSD, and should be harmless on all BSD systems.
7536 Also, include <sys/sysctl.h>, as it should be available on all
7537 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7538 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7539 use p_pid member, not kp_proc.pid.
7541 2012-07-06 Glenn Morris <rgm@gnu.org>
7543 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7545 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7547 More xmalloc and related cleanup.

7556 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7558 Omit needless casts involving void * pointers and allocation.
7559 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7560 as the former is more robust if P's type is changed.
7561 Prefer xzalloc to xmalloc + memset 0.
7562 Simplify malloc-or-realloc to realloc.
7563 Don't worry about xmalloc returning a null pointer.
7564 Prefer xstrdup to xmalloc + strcpy.
7565 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7567 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7568 alloca of a constant.

7573 hscroll is larger than the line width. Fixes long and futile
7574 looping inside extend_face_to_end_of_line (on a TTY) producing
7575 glyphs that are not needed and thrown away.
7577 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7579 * marker.c (set_marker_restricted_both): Simplify by using

7605 * xdisp.c (window_hscroll_limited): New function.
7606 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7607 coordinates when window's hscroll is set to insanely large
7610 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7612 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

7673 * fileio.c (time_error_value): Check the right error number.
7674 Problem reported by Troels Nielsen in
7675 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
7677 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7679 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7680 This should be fixed in a better way; see Eli Zaretskii in
7681 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7682 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7684 * fileio.c (time_error_value): Rename from special_mtime.
7685 The old name's problems were noted by Eli Zaretskii in
7686 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7688 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7689 This variable's comment says Emacs needs at least one GDB-visible
7690 symbol of type enum pvec_type, to work around GDB problems.
7691 The symbol's value doesn't matter.
7693 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7694 that causes compilation to fail on pre-C99 compilers.
7696 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7698 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
7699 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
7701 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7703 * buffer.c (init_buffer_once): Fix initialization of
7704 headers for buffer_defaults and buffer_local_symbols.
7705 Reported by Juanma Barranquero <lekktu@gmail.com>.
7707 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7709 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7710 * lisp.h (enum pvec_type): Use fewer bits.
7711 (PSEUDOVECTOR_SIZE_BITS): New constant.
7712 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7713 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7714 change in pvec_type.
7715 (PSEUDOVECTOR_TYPEP): New macro.
7716 (TYPED_PSEUDOVECTORP): Use it.
7717 * fns.c (internal_equal): Adapt code to extract pvectype.

7719 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
7720 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
7721 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7722 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7723 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7724 abusing vector->header.next.nbytes.
7725 (live_vector_p): Use PVEC_TYPE.
7726 (mark_object): Adapt code to extract pvectype. Use switch.
7728 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7730 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7731 Tighten new eassert a bit.
7733 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7735 Fix compilation with --enable-gcc-warnings and -O1
7737 * doprnt.c (doprnt): Change type of tem to int, initialize
7738 to avoid compiler warning. Add eassert.
7739 * search.c (simple_search): Initialize match_byte to avoid
7740 compiler warning. Add eassert.
7742 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7744 Avoid weird behavior with large horizontal scrolls.
7745 Without this change, for example, large hscroll values would
7746 mess up Emacs's display on Fedora 15 x86, presumably due to
7747 overflows in int calculations in the display code.
7748 Also, if buffers had long lines, Emacs would freeze.
7749 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7750 (set_window_hscroll): New function, containing the old guts of
7751 Fset_window_hscroll. Return the clipped value.
7752 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7753 This avoids the need to check against PTRDIFF_MAX.
7755 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7757 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7759 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7761 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7763 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7764 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7765 since GCC 4.4.6 issues a bogus warning for them.
7767 Fix bugs in file timestamp newness comparisons.
7768 * fileio.c (Ffile_newer_than_file_p):
7769 * lread.c (Fload): Use full timestamp resolution of files,
7770 not just the 1-second resolution, so that files that are only
7771 slightly newer still count as newer.
7772 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7773 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7775 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7777 * fileio.c: Improve handling of file time marker. (Bug#11852)
7778 (special_mtime): New function.
7779 (Finsert_file_contents, Fverify_visited_file_modtime):
7780 Use it to set special mtime values consistently.
7782 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7784 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7785 marker for non-existing file. (Bug#11852)
7787 2012-07-03 Glenn Morris <rgm@gnu.org>
7789 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7790 and did not make it into globals.h).
7792 2012-07-03 Tom Tromey <tromey@redhat.com>
7794 * window.c (Fset_window_margins, Fset_window_fringes)
7795 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7796 * textprop.c (Fprevious_property_change): No longer static.
7797 * syntax.c (Fsyntax_table_p): No longer static.

7819 * intervals.h: Remove EXFUNs.
7820 * fontset.h: Remove EXFUN.

7825 * w32term.h: Remove EXFUNs.
7826 * window.h: Remove EXFUNs.

7828 * xterm.h: Remove EXFUN.
7830 2012-07-03 Glenn Morris <rgm@gnu.org>
7832 * lisp.h (Frandom): Make it visible to C.
7833 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7834 buffer for invisible buffers. (Bug#1229)
7836 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7838 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7839 values which aren't power of 2.
7840 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7841 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7844 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7846 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7848 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7850 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7852 * alloc.c (allocate_vector_block): Remove redundant
7853 calls to mallopt if DOUG_LEA_MALLOC is defined.
7854 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7855 avoid calls to mallopt if zero_vector is returned.
7857 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7859 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7860 is enabled, avoid dereferencing NULL current_sblock if
7863 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7865 Cleanup basic buffer management.
7866 * buffer.h (struct buffer): Change layout to use generic vector
7867 marking code. Fix some comments. Change type of 'clip_changed'
7868 to bitfield. Remove unused #ifndef old.
7869 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7870 (GET_OVERLAYS_AT): Fix indentation.
7871 (for_each_per_buffer_object_at): New macro.
7872 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

7875 * alloc.c (allocate_buffer): Adjust to match new layout of
7876 struct buffer. Fix comment.
7877 (mark_overlay): New function.

7879 Lisp area of struct buffer.
7880 (mark_object): Use it. Adjust marking of misc objects
7881 and related comments.
7883 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7885 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7886 wrapper that is not needed because the wrapped code is a no-op (zero
7887 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7888 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7890 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7892 * alloc.c (mark_buffer): Simplify. Remove prototype.
7893 (mark_object): Add comment. Reorganize marking of vector-like
7894 objects. Use CHECK_LIVE for all vector-like objects except buffers
7895 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7896 Avoid redundant calls to mark_vectorlike for bool vectors.
7898 2012-06-30 Glenn Morris <rgm@gnu.org>
7900 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7902 * epaths.in (PATH_SITELOADSEARCH): New.
7903 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7904 This is rather than relying on --enable-locallisppath elements
7905 having "site-lisp" in their names. (Bug#10208#25, 11658)
7907 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7909 * w32proc.c (sys_select): Accept and ignore one more argument.
7911 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7913 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7914 (pselect) [!MS_DOS]: Redirect to sys_select.
7916 * sysdep.c: Don't include dos.h and dosfns.h.
7918 * process.c (sys_select):
7919 * msdos.c (sys_select): Accept one more argument and ignore it.
7921 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7922 adapt data types and code to that.
7925 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7926 which clashes with the gnulib function of the same name.
7928 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7930 * font.c (font_style_to_value, font_style_symbolic)
7931 (font_prop_validate_style): Add type checks for values in
7934 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7936 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7939 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7941 * xdisp.c (try_window_id): Undo last change.
7943 * w32.c (getwd): Adjust commentary about startup_dir.
7944 (init_environment): Always call sys_access, even in non-MSVC
7945 builds. Don't chdir to the directory of the Emacs executable.
7946 This undoes code from 1997 which was justified by the need to
7947 "avoid conflicts when removing and renaming directories". But its
7948 downside was that every relative file name was being interpreted
7949 relative to the directory of the Emacs executable, which can never
7950 be TRT. In particular, it broke sys_access when called with
7951 relative file names.
7952 (sys_access): Map GetLastError to errno.
7954 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7956 * window.h (struct window): Change type of 'fringes_outside_margins'

7960 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7963 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
7965 * gnutls.c (emacs_gnutls_handshake):
7966 Add QUIT to make the loop interruptible.
7968 2012-06-29 Glenn Morris <rgm@gnu.org>
7970 * charset.c (init_charset): Make lack of etc/charsets fatal.
7972 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7974 * editfns.c (region_limit): Fix type mismatch.
7976 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7978 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
7979 undefined. Convert from xassert to eassert.
7980 * nsmenu.m: Convert from xassert to eassert.
7981 * nsterm.m: Likewise.
7983 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7985 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7987 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7989 Avoid integer overflow on scroll-left and scroll-right.
7990 * window.c (HSCROLL_MAX): New macro.
7991 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7992 overflow when requested scroll falls outside ptrdiff_t range.
7994 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7996 * window.h (struct window): Change type of 'hscroll',
7997 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7998 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7999 Adjust users accordingly.
8000 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8001 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8002 from EMACS_INT to ptrdiff_t.
8003 (make_window): Omit redundant initialization.
8005 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8007 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8009 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8011 * window.h (struct window): Change type of 'use_time' and
8012 'sequence_number' from Lisp_Object to int.
8013 * frame.c (make_frame): Adjust users accordingly.
8014 * print.c (print_object): Likewise.
8015 * window.c (select_window, Fwindow_use_time, make_parent_window)
8016 (make_window): Likewise.
8018 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8020 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
8021 enabled with --enable-checking=[all,glyphs] configure option.
8022 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8023 adjust comments accordingly.

8074 avoid GCC warning about unused macro.
8076 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8078 * alloc.c (allocate_string): Omit intervals initialization.
8079 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8080 as in make_pure_string and make_pure_c_string.
8082 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8084 * alloc.c (allocate_string): Fix last change.
8086 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

8136 * alloc.c: Remove build_string.
8137 * lisp.h: Define build_string as static inline. This provides
8138 a better opportunity to optimize away calls to strlen when the
8139 function is called with compile-time constant argument.

8146 Use sprintf return value instead of invoking strlen on result.
8147 In the old days this wasn't portable, since some sprintf
8148 implementations returned char *. But they died out years ago and
8149 Emacs already assumes sprintf returns int.
8150 Similarly for float_to_string.
8151 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8152 * ccl.c (ccl_driver):
8153 * character.c (string_escape_byte8):

8156 * print.c (print_object):
8157 * xdisp.c (message_dolog):
8158 * xfns.c (syms_of_xfns):
8159 Use sprintf or float_to_string result to avoid need to call strlen.
8160 * data.c (Fnumber_to_string):
8161 Use make_unibyte_string, since the string must be ASCII.
8162 * lisp.h, print.c (float_to_string): Now returns int length.
8163 * term.c (produce_glyphless_glyph):
8164 Use sprintf result rather than recomputing it.
8166 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8167 * Makefile.in (ALL_CFLAGS):
8168 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
8169 * gmalloc.c, regex.c: Include <config.h> unconditionally.
8171 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8173 * dispextern.h (xstrcasecmp): Define to library function
8174 strcasecmp if available.

8190 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
8192 * gtkutil.c (get_utf8_string): Remove redundant assignment.

8195 * xfns.c (x_window): Remove redundant cast.
8197 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8199 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
8200 `const char *' to `char *' to avoid compiler warning.
8202 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8204 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8205 instead of truncating it to 63 (admittedly a generous limit).
8207 * process.c: Fix spelling and caps in comments.
8209 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
8211 * emacs.c (setpgrp): Remove definition, unused.

8258 Remove unnecessary forward decls.
8260 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8262 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

8264 * dispnew.c (Fsleep_for, sit_for):
8265 * keyboard.c (kbd_buffer_get_event):
8266 * process.c (Faccept_process_output):
8267 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8268 This improves on the previous patch, which introduced a bug
8269 when time_t is unsigned and as wide as intmax_t.
8270 See <http://bugs.gnu.org/9000#51>.
8272 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8274 * dispnew.c (sit_for, Fsleep_for):
8275 * keyboard.c (kbd_buffer_get_event):

8288 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
8289 Privately reported by Herbert J. Skuhra.
8290 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
8292 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
8293 not make_lisp_timeval, when the argument is of type EMACS_TIME.
8295 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8297 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
8298 last argument of make_unibyte_string.
8300 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
8301 language ID in the event parameters.
8303 * w32term.c (w32_read_socket): Put the new keyboard codepage into
8304 event.code, not the obscure "character set ID".

8327 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
8328 Privately reported by Herbert J. Skuhra.

8331 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
8332 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
8333 Don't assume EMACS_TIME and struct timeval are the same type.
8335 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8337 Support higher-resolution time stamps (Bug#9000).
8338 The time stamps are only nanosecond-resolution at the C level,
8339 since that's the best that any real-world system supports now.
8340 But they are picosecond-resolution at the Lisp level, as that's
8341 easy, and leaves room for future OS improvements.
8343 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8346 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8347 Don't get current time unless it's needed.
8349 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8350 now provides it if it's absent.
8351 (start_atimer): Port to higher-res time stamps.
8352 Check for time stamp overflow. Don't get current time more
8353 often than is needed.
8355 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8356 Include systime.h, not time.h.
8357 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8359 * dired.c: Include stat-time.h.
8360 (Ffile-attributes): File times now have higher resolution.
8362 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8363 (struct image): Timestamp now has higher resolution.
8365 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8366 has at least microseconds now. All uses removed.
8367 (update_frame, update_single_window, update_window, update_frame_1)
8368 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8369 (duration_to_sec_usec): Remove; no longer needed.
8371 * editfns.c (time_overflow): Now extern.
8372 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8373 (float-time, Fformat_time_string, Fcurrent_time_string)
8374 (Fcurrent_time_zone): Accept and generate higher-resolution
8376 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
8377 (decode_time_components, lisp_seconds_argument): New functions.
8378 (make_time): Now static.
8379 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8380 Report an error if the time is invalid, rather than having the caller
8383 * fileio.c: Include <stat-time.h>
8384 (Fcopy_file): Copy higher-resolution time stamps.
8385 Prefer to set the time stamp via a file descriptor if that works.
8386 (Fset_file_times, Finsert_file_contents, Fwrite_region)
8387 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8388 (Fvisited_file_modtime, Fset_visited_file_modtime):
8389 Support higher-resolution time stamps.
8391 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8393 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8395 * image.c (prepare_image_for_display, clear_image_cache)
8396 (lookup_image): Port to higer-resolution time stamps.
8398 * keyboard.c (start_polling, bind_polling_period):
8399 Check for time stamp overflow.
8400 (read_char, kbd_buffer_get_event, timer_start_idle)
8401 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8402 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8403 Port to higher-resolution time stamps. Do not assume time_t is signed.
8404 (decode_timer): New function. Timers are now vectors of length 9,
8405 not 8, to accommodate the picosecond component.
8406 (timer_check_2): Use it.
8408 * nsterm.m (select_timeout, timeval_subtract): Remove.
8409 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8410 as they're a bit more accurate and handle overflow better.
8411 (ns_select): Change prototype to be compatible with pselect.
8412 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8413 * nsterm.h (ns_select): Adjust prototype.
8415 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8416 us-resolution time stamps.
8417 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8419 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8421 * lisp.h (time_overflow): New decl.
8422 (wait_reading_process_output): First arg is now intmax_t, not int,
8423 to accommodate larger waits.
8425 * process.h (struct Lisp_Process.read_output_delay):
8426 Now counts nanoseconds, not microseconds.
8427 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8429 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8430 (wait_reading_process_output):
8431 Port to ns-resolution time stamps.
8432 (Faccept_process_output, wait_reading_process_output):
8433 Check for time stamp overflow. Do not assume time_t is signed.
8434 (select_wrapper): Remove; we now use pselect.
8435 (Fprocess_attributes): Now generates ns-resolution time stamps.
8437 * sysdep.c: Include utimens.h. Don't include utime.h
8438 or worry about struct utimbuf; gnulib does that for us now.
8439 (gettimeofday): Remove; gnulib provides a substitute.
8440 (make_timeval): New function.
8441 (set_file_times): Now sets ns-resolution time stamps.
8442 New arg FD; all uses changed.
8443 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8444 (system_process_attributes):
8445 Now returns ns-resolution time stamp. All uses changed.
8446 Check for time stamp overflow.
8448 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8449 provides a substitute now.
8451 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8452 since it guarantees struct timespec.
8453 (EMACS_TIME): Now struct timespec, so that we can support
8454 ns-resolution time stamps.
8455 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8456 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8457 (EMACS_USECS): Remove.
8458 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8459 so multiply the arg by 1000 before storing it.
8460 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8462 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8463 Port to ns-resolution time stamps.
8464 (EMACS_TIME_NEG_P): Remove; replaced by....
8465 (EMACS_TIME_SIGN): New macro.
8466 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8467 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8468 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8469 (make_timeval, make_lisp_time, decode_time_components): New decls.
8470 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8471 that it mishandled time_t overflow. You can't compare by subtracting!
8472 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8473 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8475 * term.c: Include <sys/time.h>.
8476 (timeval_to_Time): New function, for proper overflow wraparound.
8477 (term_mouse_position, term_mouse_click): Use it.
8479 * undo.c (record_first_change): Support higher-resolution time stamps
8481 (Fprimitive_undo): Use them when restoring time stamps.
8483 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8484 (w32_get_internal_run_time):
8485 Port to higher-resolution Emacs time stamps.
8486 (ltime): Now accepts single 64-bit integer, as that's more convenient
8489 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8491 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8492 for compatibility with pselect. Support ns-resolution time stamps.
8494 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8496 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8497 Check for time stamp overflow, and support ns-resolution time stamps.
8499 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8500 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8501 (timeval_subtract): Remove; no longer needed.
8502 (XTflash, XTring_bell, x_wait_for_event):
8503 Port to ns-resolution time stamps. Don't assume time_t is signed.
8505 2012-06-22 Chong Yidong <cyd@gnu.org>
8507 * xdisp.c (x_consider_frame_title): Revert last change.
8509 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8511 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8512 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8513 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8514 staticidx goes up to 1597 out of 1600 = 0x640.)
8516 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8518 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8519 Otherwise, the umask might be mistakenly 0 while handling input signals.
8521 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
8523 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

8528 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
8529 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
8530 access to `contents' member of Lisp_Vector objects with AREF and ASET
8533 2012-06-19 Chong Yidong <cyd@gnu.org>
8535 * frame.c (delete_frame): When selecting a frame on a different
8536 text terminal, do not alter the terminal's top-frame.

8539 frame's selected window and its terminal's top-frame.
8540 (unwind_format_mode_line): Restore them.
8541 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8543 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8544 since tty frames can be explicitly named.
8545 (prepare_menu_bars): Likewise.
8547 * term.c (Ftty_top_frame): New function.
8549 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8551 Port byte-code-meter to modern targets.
8552 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8553 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8554 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8555 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
8556 (METER_1, METER_2): Simplify.
8558 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
8560 * data.c (Fdefalias): Return `symbol' (bug#11686).
8562 2012-06-18 Martin Rudalics <rudalics@gmx.at>
8564 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8565 gets killed during executing of this function (Bug#11665).
8566 Try to always return Qt when the buffer has been actually killed.
8567 (Vkill_buffer_query_functions): In doc-string say that functions
8568 run by this hook should not change the current buffer.
8570 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8572 Fix recently-introduced process.c problems found by static checking.
8573 * process.c (write_queue_push, write_queue_pop, send_process):
8574 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
8575 (write_queue_pop): Fix pointer signedness problem.
8576 (send_process): Remove unused local.
8578 2012-06-17 Chong Yidong <cyd@gnu.org>
8580 * xdisp.c (redisplay_internal): No need to redisplay terminal
8581 frames that are not on top.
8583 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
8585 * process.c (make_process): Initialize write_queue.
8586 (write_queue_push, write_queue_pop): New functions.
8587 (send_process): Use them to maintain correct ordering of process
8590 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
8592 * lisp.h (eassert): Assume C89 or later.
8593 This removes the need for CHECK.
8594 (CHECK): Remove. Its comments about always evaluating its
8595 argument were confusing, as 'eassert' typically does not evaluate
8598 * coding.c (produce_chars): Use ptrdiff_t, not int.
8600 * xterm.c (x_draw_underwave): Check for integer overflow.
8601 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
8603 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>

8786 code works fine either way, and efficiency is not a concern here,
8787 as the union type is for debugging, not for production.
8788 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8789 Use an inline function on all platforms when using the union type,
8790 since this is simpler and 'static inline' can be used portably
8792 (LISP_INITIALLY_ZERO): New macro.

8934 * doprnt.c (doprnt): Truncate multibyte char correctly.
8935 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8936 would mishandle a string argument "Xc" if X was a multibyte

8938 rather than including all of X.

9021 and 'double' in a couple of places.
9023 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9025 * xdisp.c (handle_stop): Detect whether we have overlay strings
9026 loaded by testing it->current.overlay_string_index to be
9027 non-negative, instead of checking whether n_overlay_strings is
9028 positive. (Bug#11587)

9038 * search.c (search_buffer): Remove calls to

9040 maybe_unify_char, which was the cause of relocation of buffer text
9043 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9045 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9046 for the duration of call to load_charset, to avoid problems with
9047 callers of maybe_unify_char that access buffer text through C
9050 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9051 decrement the inhibition flag, instead of just setting or

9057 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

9061 (gray_bitmap_bits): Remove; no longer needed.

9103 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9105 Do not create empty overlays with the evaporate property (Bug#9642).
9106 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9107 Bug#9642, but explicitly check that the buffer the overlay would
9108 be moved to is live and rearrange lines to make sure that errors
9109 will not put the overlay in an inconsistent state.
9110 (Fdelete_overlay): Cosmetics.
9112 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9114 * w32term.c (my_bring_window_to_top): New function.
9115 (x_raise_frame): Use handle returned by DeferWindowPos, which
9116 could be different from the original one.

9120 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9121 by calling BringWindowToTop.
9123 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9124 (WM_EMACS_END): Increase by one.
9126 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9128 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9129 This avoids undefined behavior that might cause the eassert
9130 to not catch an out-of-range value.
9132 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9134 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9135 Update dependencies.
9137 2012-05-27 Eli Zaretskii <eliz@gnu.org>

9144 when referring to sectname field in printf format.
9146 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9148 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9149 Only r_alloc_inhibit_buffer_relocation needed to be added;
9150 the others were already declared.
9152 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9153 before checking whether it's out of range. Put the check inside
9155 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9157 2012-05-27 Ken Brown <kbrown@cornell.edu>
9159 * callproc.c (Fcall_process): Restore a line that was accidentally
9160 commented out in the 2011-02-13 change (bug#11547).
9162 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9164 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9165 defined on ralloc.c.
9167 * buffer.c [REL_ALLOC]: Remove prototypes of
9168 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9169 they are now on lisp.h.
9171 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9173 * search.c (search_buffer): Use it to inhibit relocation of buffer
9174 text while re_search_2 is doing its job, because re_search_2 is
9175 passed C pointers to buffer text. (Bug#11519)
9177 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9180 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9181 state after an additional call to move_it_in_display_line_to, keep
9182 the values of it->max_ascent and it->max_descent found for the
9184 (pos_visible_p): Revert the comparison against bottom_y to what it
9185 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9188 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9190 Fix coding-related core dumps with gcc -ftrapv.
9191 The code was computing A - B, where A and B are pointers, and B is
9192 random garbage. This can lead to core dumps on platforms that
9193 have special pointer registers, and it also leads to core dumps on
9194 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9195 A - B only when B is initialized properly.
9196 * coding.c (coding_set_source, coding_set_destination): Return void.
9197 (coding_change_source, coding_change_destinations): New functions,
9198 with the old behaviors of coding_set_source and coding_set_destination.
9199 All callers that need an offset changed to use these new functions.
9201 2012-05-26 Glenn Morris <rgm@gnu.org>
9203 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9205 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9207 Extend mouse support on W32 text-mode console.
9208 * xdisp.c (draw_row_with_mouse_face):
9209 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9211 * w32console.c: Include window.h.
9212 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9214 (initialize_w32_display): Initialize mouse-highlight data.
9216 * w32inevt.c: Include termchar.h and window.h.
9217 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9218 moves, call note_mouse_highlight. If help_echo changed, call
9219 gen_help_event to produce help-echo message in the echo area.
9220 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9223 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9225 * lread.c (read1): Simplify slightly to avoid an overflow warning
9226 with GCC 4.7.0 on x86-64.
9228 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9230 * bidi.c (bidi_mirror_char): Revert last change: an int is
9231 definitely wide enough here.
9233 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9235 Fix integer width and related bugs (Bug#9874).

9242 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
9243 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9245 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9246 (allocate_pseudovector):
9247 Use int, not EMACS_INT, where int is wide enough.
9248 (inhibit_garbage_collection, Fgarbage_collect):
9249 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9250 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9251 int might not be wide enough.
9252 (bidi_cache_search, bidi_cache_find, bidi_init_it)

9255 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9256 (bidi_level_of_next_char, bidi_move_to_visually_next):
9257 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9258 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9259 (Fkill_buffer, Fset_buffer_major_mode)
9260 (advance_to_char_boundary, Fbuffer_swap_text)
9261 (Fset_buffer_multibyte, overlays_at, overlays_in)

9265 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9266 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9267 (Foverlay_recenter, last_overlay_modification_hooks_used)
9268 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9270 (validate_region): Omit unnecessary test for b <= e,
9271 since that's guaranteed by the previous test.
9272 (adjust_overlays_for_delete): Avoid pos + length overflow.
9273 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9274 (report_overlay_modification):
9275 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9276 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9277 Omit pointer cast, which isn't needed anyway, and doesn't work
9278 after the EMACS_INT -> ptrdiff_t change.
9279 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9280 * buffer.h: Adjust decls to match defn changes elsewhere.

9285 not int, to avoid needless 32-bit limit on 64-bit hosts.
9286 (exec_byte_code): Use tighter memory-full test, one that checks
9287 for alloca overflow. Don't compute the address of the object just
9288 before an array, as that's not portable. Use EMACS_INT, not
9289 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9290 * callint.c (Fcall_interactively):
9291 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9292 * callproc.c (call_process_kill, Fcall_process):

9302 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9303 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9304 (casify_object): Avoid integer overflow when overallocating buffer.
9305 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9306 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9307 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9308 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9309 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9310 integers are now checked earlier. All uses replaced with XINT.
9312 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9313 For CCL_MapSingle, check that content and value are in int range.
9314 (ccl_driver, Fregister_code_conversion_map):
9315 Check that Vcode_version_map_vector is a vector.
9316 (resolve_symbol_ccl_program): Check that vector header is in range.
9317 Always copy the vector, so that we can check its contents reliably
9318 now rather than having to recheck each instruction as it's being
9319 executed. Check that vector words fit in 'int'.
9320 (ccl_get_compiled_code, Fregister_ccl_program)
9321 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9322 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9323 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9324 contents are in range.
9325 (Fccl_execute_on_string): Check that status is in range.
9326 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9327 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9328 Accept and return EMACS_INT, not int, because callers can pass values
9330 (c_string_width, strwidth, lisp_string_width, chars_in_text)

9333 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9334 (string_escape_byte8, Fget_byte):
9335 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9336 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9337 avoid mishandling large integers.
9338 * character.h: Adjust decls to match defn changes elsewhere.

9347 (Fdefine_charset_internal): Check ranges here, more carefully.
9348 Don't rely on undefined behavior with signed left shift overflow.
9349 Don't assume unsigned int fits into fixnum, or that fixnum fits
9350 into unsigned int. Don't require max_code to be a valid fixnum;
9351 that's not true for gb10830 4-byte on a 32-bit host. Allow
9352 invalid_code to be a cons, for the same reason. Require code_offset
9353 to be a character. Avoid int overflow if max_char is close
9355 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9356 this is intended anyway and avoids some undefined behavior.
9357 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9358 INDEX_TO_CODE_POINT, as that's what it expects.
9359 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9360 * charset.h (DECODE_CHAR): Return int, not unsigned;
9361 this is what was intended anyway, and it avoids undefined behavior.
9362 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9363 integer-overflow issues.
9364 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9365 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9366 where the argument is EMACS_INT, and this behavior is not intended.
9367 * chartab.c (Fmake_char_table, Fset_char_table_range)
9368 (uniprop_get_decoder, uniprop_get_encoder):
9369 Don't assume fixnum fits in int.
9370 * cmds.c (move_point): New function, that does the gist of
9371 Fforward_char and Fbackward_char, but does so while checking
9372 for integer overflow more accurately.
9373 (Fforward_char, Fbackward_char): Use it.
9374 (Fforward_line, Fend_of_line, internal_self_insert)
9375 (internal_self_insert):
9376 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9377 Fix a FIXME, by checking for integer overflow when calculating
9378 target_clm and actual_clm.

9413 Don't access memory outside of the args array.
9414 (Fdefine_coding_system_internal): Check for charset-id overflow.
9415 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
9416 result of ENCODE_CHAR.

9435 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
9436 Do not attempt to compute the address of the object just before a
9437 buffer; this is not portable.
9439 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9440 (Faset): Use int, not EMACS_INT, where int is wide enough.
9441 (Fstring_to_number): Don't assume fixnums fit in int.

10168 (mark_x, adjust_lnnoptrs, unrelocate_symbols):

10174 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10175 already have overlays loaded.
10176 (handle_single_display_spec): Before returning without displaying
10177 fringe bitmap, synchronize the bidi iterator with the main display
10178 iterator, by calling iterate_out_of_display_property.
10179 (iterate_out_of_display_property): Detect buffer iteration by
10180 testing that it->string is a Lisp string.
10181 (get_next_display_element): When the current object is exhausted,
10182 and there's something on it->stack, call set_iterator_to_next to
10183 proceed with what's on the stack, instead of returning zero.
10184 (set_iterator_to_next): If called at the end of a Lisp string,
10185 proceed to consider_string_end without incrementing string
10186 position. Don't increment display vector index past the end of

10188 (pos_visible_p): Don't report a position visible when move_it_to
10189 stopped at the last line of window, which happens to be scanned
10190 backwards by the bidi iteration. (Bug#11464)
10192 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10194 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10195 and right-margin display specs even if the spec is invalid or we
10196 are on a TTY, and thus unable to display on the fringes.
10197 That's because the text with the property will not be displayed anyway,
10198 so we need to signal to the caller that this is a "replacing"
10199 display spec. This fixes display when the spec is invalid or we

10204 * unexaix.c (make_hdr): Fix typo in prototype.
10205 This bug broke the build on AIX. Problem reported by Gilles Pion.
10207 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10209 * keyboard.c (kbd_buffer_get_event): Read special events also in
10210 batch mode. (Bug#11415)
10212 2012-05-12 Glenn Morris <rgm@gnu.org>
10214 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10216 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10218 * lisp.mk (lisp): Add newcomment.elc.
10220 2012-05-12 Glenn Morris <rgm@gnu.org>
10222 * Makefile.in (MKDIR_P): New, set by configure.
10223 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10225 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10227 Remove unused function hourglass_started.
10228 * dispextern.h (hourglass_started):
10229 * w32fns.c (hourglass_started):
10230 * xdisp.c (hourglass_started): Remove.
10232 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10234 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10235 Update dependencies.
10237 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10239 * xgselect.c (xg_select): Put maxfds+1 into a var.
10240 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10242 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10244 2012-05-10 Dave Abrahams <dave@boostpro.com>
10246 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10247 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10249 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10251 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10252 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10253 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10254 Initialize xd_registered_buses.
10256 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10258 Untag more efficiently if USE_LSB_TAG.
10259 This is based on a proposal by YAMAMOTO Mitsuharu in
10260 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10261 For an admittedly artificial (nth 8000 longlist) benchmark on
10262 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10263 Emacs's overall text size by 1%.
10264 * lisp.h (XUNTAG): New macro.
10265 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10266 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10267 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10268 * eval.c (Fautoload):
10269 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10270 * frame.h (XFRAME): Use XUNTAG.
10272 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10273 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10274 Remove unportable assumptions about print widths of types like
10276 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10277 intptr_t when converting between pointer and integer, to avoid GCC
10278 warnings about wrong width.
10280 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10282 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10283 stack for each reader_thread, instead of defaulting to 8MB
10284 determined by the linker. This avoids failures in creating
10285 subprocesses on Windows 7, see the discussion in this thread:
10286 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10288 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10290 Fix up display of the *Minibuf-0* buffer in the mini window.
10291 * keyboard.c (read_char): Don't clear the echo area if there's no
10293 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10294 contents of *Minibuf-0*) if there's no message displayed in its stead.
10296 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10298 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10301 2012-05-06 Chong Yidong <cyd@gnu.org>
10303 * lisp.mk (lisp): Update.
10305 2012-05-05 Jim Meyering <meyering@redhat.com>
10307 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10309 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10311 * data.c (PUT_ERROR): New macro.
10312 (syms_of_data): Use it. Add new error type `user-error'.
10313 * undo.c (user_error): New function.
10314 (Fprimitive_undo): Use it.
10315 * print.c (print_error_message): Adjust print style for `user-error'.
10316 * keyboard.c (user_error): New function.
10317 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10319 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10321 Do not limit current-time-string to years 1000..9999.
10322 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10323 (Fcurrent_time_string): Support any year that is supported by the
10324 underlying localtime representation. Don't use asctime, as it
10325 has undefined behavior for years outside the range -999..9999.
10327 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10329 Fix race conditions involving setenv, gmtime, localtime, asctime.
10330 Without this fix, interrupts could mess up code that uses these
10331 nonreentrant functions, since setting TZ invalidates existing
10332 tm_zone or tzname values, and since most of these functions return
10333 pointers to static storage.
10334 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10335 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10336 Grow the critical sections to include not just invoking
10337 localtime/gmtime, but also accessing these functions' results
10338 including their tm_zone values if any, and any related TZ setting.
10339 (format_time_string): Last arg is now struct tm *, not struct tm **,
10340 so that the struct tm is saved in the critical section.
10341 All callers changed. Simplify allocation of initial buffer, partly
10342 motivated by the fact that memory allocation needs to be outside
10343 the critical section.
10345 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10347 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10348 with RESET_INTERVAL.
10350 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10351 Remove duplicated buffer name initialization.
10353 2012-05-02 Jim Meyering <jim@meyering.net>
10355 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10357 * xfns.c (x_window): Use xstrdup (Bug#11375).
10359 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10361 * xdisp.c (pos_visible_p): If already at a newline from the
10362 display string before the 'while' loop, don't walk back the glyphs
10363 from it3.glyph_row. Solves assertion violation when the display
10364 string begins with a newline (egg.el). (Bug#11367)
10366 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10368 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10371 2012-05-01 Glenn Morris <rgm@gnu.org>
10373 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10374 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10375 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10376 All were removed before 23.1.
10378 * dispnew.c: Remove HAVE_LIBNCURSES test;
10379 it is always true on relevant platforms.
10381 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10382 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10384 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10386 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10388 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10389 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10392 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10394 Do not avoid creating empty evaporating overlays (Bug#9642).
10395 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10396 That is, do not delete an evaporating overlay if it becomes
10397 empty after its bounds are adjusted to fit within its buffer.
10398 This fix caused other problems, and I'm reverting it until we get
10399 to the bottom of them.
10401 2012-04-27 Chong Yidong <cyd@gnu.org>
10403 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10405 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10407 * xdisp.c (pos_visible_p): If the window start position is beyond
10408 ZV, start the display from buffer beginning. Prevents assertion
10409 violation in init_iterator when the minibuffer window is scrolled
10410 via the scroll bar.
10412 * window.c (window_scroll_pixel_based): Likewise.
10414 2012-04-27 Chong Yidong <cyd@gnu.org>
10416 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10418 2012-04-27 Glenn Morris <rgm@gnu.org>
10420 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10421 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10423 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10425 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10426 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10428 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10430 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10431 display element, check also the underlying string or buffer
10432 character. (Bug#11341)
10434 * w32menu.c: Include w32heap.h.
10435 (add_menu_item): If the call to AppendMenuW (via
10436 unicode_append_menu) fails, disable Unicode menus only if we are
10437 running on Windows 9X/Me.
10439 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10441 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10442 (xgetint): Add missing shift for LSB tags.
10444 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10446 * keyboard.c (read_char): Don't wipe echo area for select window
10447 events: These might get delayed via `mouse-autoselect-window'
10450 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10452 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10453 manipulation of :loaded-from data.
10455 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10457 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10458 now a cons (bug#11311).
10460 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10462 Do not create empty overlays with the evaporate property (Bug#9642).
10463 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10464 if it becomes empty after its bounds are adjusted to fit within
10465 its buffer. Without this fix, in a nonempty buffer (let ((o
10466 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10467 yields an empty overlay that has the evaporate property, which is
10468 not supposed to happen.
10470 Fix minor GTK3 problems found by static checking.
10471 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

10476 (emacs_fixed_class_init): Omit unused local.
10477 (emacs_fixed_child_type): Remove; unused.

10479 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10480 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10481 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10482 (EMACS_FIXED_GET_CLASS): Remove; unused.
10483 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.

10488 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10490 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10491 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10492 (__malloc_size_t, __malloc_ptrdiff_t):
10493 Remove. All uses removed, replaced by the definiens if needed,
10494 since we can assume C89 or better now.
10495 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

10503 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10504 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10505 Define using prototypes, not old style.
10506 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):

10512 Omit no-longer-needed casts.
10513 (valloc): Use getpagesize, not __getpagesize.
10514 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
10515 (struct hdr): The 'magic' member is now size_t, not unsigned long.
10517 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
10519 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

10570 * alloc.c: Handle unusual debugging option combinations.
10571 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
10572 since the two debugging options are incompatible.
10573 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
10575 (mem_init, mem_insert, mem_insert_fixup):
10576 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

10586 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10587 Use Emacs indenting style more consistently. Avoid some casts.
10588 Use 'double' consistently rather than mixing 'float' and 'double'.
10590 2012-04-21 Eduard Wiebe <usenet@pusto.de>
10592 * sysdep.c (list_system_processes, system_process_attributes):

10647 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
10648 -Wunused-result, -Wunused-variable. This should go away once
10649 the Emacs and Gnulib regex code is merged.
10650 (xmalloc, xrealloc): Now static.
10652 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

10669 New extern decls, to avoid calling undeclared functions.
10670 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
10671 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
10672 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10673 (NEED_MEM_INSERT): New macro.
10674 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10675 Remove one incorrect comment and fix another.

10689 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
10690 Remove decls. This fixes an "It stinks!".
10692 * alloc.c (which_symbols): Fix alignment issue / type clash.
10694 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
10696 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
10697 (struct Lisp_Misc_Any): Likewise.
10698 (struct Lisp_Free): Likewise.
10699 * alloc.c (union aligned_Lisp_Symbol): Define.

10709 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
10710 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
10711 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10712 * s/netbsd.h, s/sol2-6.h:
10713 Remove definition of GC_MARK_STACK, since the default now works.
10714 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
10715 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
10716 no longer the default.
10717 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
10719 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
10721 * lread.c (lisp_file_lexically_bound_p):
10722 Fix hang at ";-*-\n" (bug#11238).
10724 2012-04-14 Eli Zaretskii <eliz@gnu.org>
10726 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

10738 2012-04-13 Reuben Thomas <rrt@sc3d.org>
10740 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
10742 2012-04-11 Daniel Colascione <dancol@dancol.org>
10744 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10745 against is gone. It's better to use vfork now so that when Cygwin
10746 gains a new, working vfork, we use it automatically (bug#10398).
10748 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
10750 * window.c (save_window_save): Obey window-point-insertion-type.

10766 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
10768 * w32.c (w32_delayed_load): Record the full path of the library
10769 being loaded (bug#10424).
10771 2012-04-09 Glenn Morris <rgm@gnu.org>
10773 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
10774 not just in the obarray, before snarfing them. (Bug#11036)
10776 * Makefile.in ($(leimdir)/leim-list.el):
10777 Pass EMACS rather than BUILT_EMACS.
10779 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
10781 * process.c (make_process):
10782 * process.h: Add integer `gnutls_handshakes_tried' member to

10791 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10792 attempts per process (connection).
10794 2012-04-09 Chong Yidong <cyd@gnu.org>
10796 * eval.c (Fuser_variable_p, user_variable_p_eh)
10797 (lisp_indirect_variable): Functions deleted.
10798 (Fdefvar): Caller changed.
10800 * callint.c (Finteractive, Fcall_interactively):
10801 * minibuf.c (Fread_variable): Callers changed.
10803 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10805 * xdisp.c (set_cursor_from_row): If the display string appears in
10806 the buffer at position that is closer to point than the position
10807 after the display string, display the cursor on the first glyph of
10808 the display string. Fixes cursor display when a 'display' text
10809 property immediately follows invisible text. (Bug#11094)
10811 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10813 composite.c: use 'double' consistently
10814 * composite.c (get_composition_id): Use 'double' consistently
10815 instead of converting 'float' to 'double' and vice versa; this is
10816 easier to understand and avoids a GCC warning.
10818 2012-04-09 Glenn Morris <rgm@gnu.org>
10820 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10821 preparation for dumping it with emacs. (Bug#4789)

10842 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
10843 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10844 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10845 objects, as mark_maybe_pointer will catch them otherwise.
10846 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
10847 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

10856 Support building on MS-Windows with libxml2.
10858 * makefile.w32-in (OBJ2): Add xml.$(O).
10859 (GLOBAL_SOURCES): Add xml.c.
10860 ($(BLD)/xml.$(O)): New dependency list.
10862 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10863 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10864 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10865 [!WINDOWSNT]: New macros.
10866 (init_libxml2_functions, libxml2_loaded_p): New functions.
10867 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10868 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10869 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10870 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10872 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10873 Call init_libxml2_functions before calling libxml2 functions.
10874 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10876 * emacs.c: Don't include libxml/parser.h.
10877 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10878 xmlCleanupParser directly.
10880 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10882 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10884 * indent.c (Fvertical_motion): If there is a display string at
10885 point, use it.vpos to compute how many lines to backtrack after
10886 move_it_to point. (Bug#11133)
10888 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10890 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10891 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10892 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10893 macros related to unification of CJK characters. For the details,
10894 see the discussion following the message here:
10895 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10897 2012-04-04 Chong Yidong <cyd@gnu.org>
10899 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10901 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10903 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

10911 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10913 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10914 position we get to after a call to move_it_to fails the
10915 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10916 only if we wind up in a string from display property. (Bug#11063)
10918 * window.c (Fdelete_other_windows_internal): Invalidate the row
10919 and column information about mouse highlight, so that redisplay
10920 restores it after reallocating the glyph matrices. (Bug#7464)
10922 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10923 string comes from a `display' text property, use the buffer
10924 position of that property as if we actually saw that position in
10926 (move_it_by_lines): Remove the assertion that
10927 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10928 violated when there's a before-string at the beginning of a line.
10931 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10933 * xdisp.c (append_space_for_newline): If the default face was
10934 remapped, use the remapped face for the appended newline.
10935 (extend_face_to_end_of_line): Use the remapped default face for
10936 extending the face to the end of the line.
10937 (display_line): Call extend_face_to_end_of_line when the default
10938 face was remapped. (Bug#11068)

10960 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10961 (command_loop_1): Use it; inhibit selection update for
10962 handle-select-window too (Bug#8996).

10966 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10968 2012-03-25 Kenichi Handa <handa@m17n.org>
10970 * dispextern.h (struct glyph): Change the bit length of
10971 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10973 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10975 * s/ms-w32.h (tzname): Include time.h before redirecting to

10980 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10983 * xterm.c (XTread_socket): Only modify handling_signal if
10984 !SYNC_INPUT. (Bug#11080)
10986 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10988 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10989 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10990 when fetching a multibyte character consumes more bytes than
10991 CHAR_BYTES returns, due to unification of CJK characters in
10992 string_char. (Bug#11073)
10994 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10996 * process.c (wait_reading_process_output): Handle pty disconnect
10997 by refraining from sending oneself a SIGCHLD (bug#10933).
10999 2012-03-22 Chong Yidong <cyd@gnu.org>
11001 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11003 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

11030 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11031 that is not from display property, accept the row as a "cursor
11032 row" if one of the string's character has a non-nil `cursor'
11033 property. Fixes cursor positioning when there are newlines in
11034 overlay strings, e.g. in icomplete.el. (Bug#11035)
11036 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11038 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11040 2012-03-12 Chong Yidong <cyd@gnu.org>
11042 * eval.c (inhibit_lisp_code): Rename from
11043 inhibit_window_configuration_change_hook; move from window.c.
11045 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11046 * window.c (run_window_configuration_change_hook)
11047 (syms_of_window): Callers changed.
11049 2012-03-11 Chong Yidong <cyd@gnu.org>
11051 * keymap.c (Fkey_description): Doc fix (Bug#9700).

11055 2012-03-10 Chong Yidong <cyd@gnu.org>
11057 * frame.c (other_visible_frames): Don't assume the selected frame
11058 is visible (Bug#10955).
11060 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11062 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11064 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11066 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11067 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11070 2012-03-03 Glenn Morris <rgm@gnu.org>
11072 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11074 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11077 position past the first glyph_row that ends at ZV. (Bug#10902)
11078 (redisplay_window, next_element_from_string): Fix typos in
11080 (redisplay_window): Pass to move_it_vertically the margin in
11081 pixels, not in screen lines.
11083 2012-03-02 Glenn Morris <rgm@gnu.org>
11085 * buffer.c (buffer-list-update-hook): Doc fix.
11087 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11089 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11090 push_it before setting up the iterator for the first overlay
11091 string, even if we have an empty string loaded.
11092 (next_overlay_string): If there's an empty string on the iterator
11093 stack, pop the stack. (Bug#10903)
11095 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11097 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11098 Suggested by Stefan Monnier in
11099 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11100 * alloc.c (widen_to_Lisp_Object): New static function.
11101 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11102 and widening them to Lisp_Objects. This would work even if
11103 USE_LSB_TAG is defined and wide integers are used, which might
11104 happen in a future version of Emacs.
11106 2012-02-25 Chong Yidong <cyd@gnu.org>
11108 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

11117 * keyboard.c (process_special_events): Handle all X selection
11118 requests in kbd_buffer, not just the next one (Bug#8869).
11120 2012-02-23 Chong Yidong <cyd@gnu.org>
11122 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11123 call when setting menu-bar-lines and tool-bar-lines parameters.
11124 (unwind_create_frame_1): New helper function.

11145 when computing $valmask.
11147 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11148 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11149 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11150 It's useless in that case, and it can cause problems on hosts
11151 that allocate halves of EMACS_INT values separately.
11152 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11153 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11154 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11155 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11156 it avoids undefined behavior on hosts where shifting right by more
11157 than the word width has undefined behavior.
11159 2012-02-19 Chong Yidong <cyd@gnu.org>
11161 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11162 (Funhandled_file_name_directory, Ffile_name_as_directory)

11204 * window.c (Fdelete_window_internal): Invalidate the mouse
11205 highlight (Bug#9904).
11207 2012-02-12 Glenn Morris <rgm@gnu.org>

11239 * buffer.c (Fbuffer_local_variables)
11240 (buffer_lisp_local_variables): Handle unbound vars correctly;
11241 don't let Qunbound leak into Lisp.
11243 2012-02-07 Glenn Morris <rgm@gnu.org>
11245 * image.c (Fimagemagick_types): Doc fix.
11247 * image.c (imagemagick-render-type): Change it from a lisp object

11282 Handle overflow when computing char display width (Bug#9496).
11283 * character.c (char_width): Return EMACS_INT, not int.
11284 (char_width, c_string_width): Check for overflow when
11285 computing the width; this is possible now that individual

11311 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to

11318 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11319 first 2 arguments are identical. This makes inserting large
11320 output from a subprocess an order of magnitude faster on

11774 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
11775 verifies glyph row's hash code--we have just reallocated the

11941 is set, removing the need for VIRT_ADDRESS_VARIES.
11942 (PURE_P): Use a more-efficient implementation that needs just one

11959 behave as if the cursor position were at the window margin.
11961 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11962 and the cursor position is out of bounds, behave as if the cursor
11963 position were at the window margin. (Bug#10075)
11965 2011-11-18 Chong Yidong <cyd@gnu.org>
11967 * window.c (Fwindow_combination_limit): Make first argument

11989 compute_line_metrics.
11990 (compute_line_metrics): Call row_hash, instead of computing the
11993 * dispnew.c (verify_row_hash): Call row_hash for computing the
11994 hash code of a row, instead of duplicating code from xdisp.c.
11996 * dispextern.h (row_hash): Add prototype.
11998 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12000 * frame.c (delete_frame): Don't delete the terminal when the last

12026 (Fsplit_window_internal, saved_window)
12027 (Fset_window_configuration, save_window_save): Rename all
12028 occurrences of window_nest to window_combination_limit.

12036 * xdisp.c (display_line): Move the call to
12037 highlight_trailing_whitespace before the call to

12049 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12050 with user-defined heap size. Bump the default size of the temacs

12505 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12506 * editfns.c: Rewrite current-time-zone so that it invokes
12507 the equivalent of (format-time-string "%Z") to get the time zone name.
12508 This fixes a bug when the time zone name contains characters that
12509 need converting from the system time locale to Emacs internal format.
12510 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12511 that patch fixed format-time-string to do the conversion, but
12512 I forgot to fix current-time-zone.
12513 (format_time_string): New function, containing most of
12514 what Fformat_time_string used to contain.
12515 (Fformat_time_string): Rewrite in terms of format_time_string.
12516 This doesn't change this function's behavior.
12517 (current-time-zone): Rewrite to use format_time_string.
12518 This fixes the bug reported by Michael Schierl in
12519 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12520 Jason Rumney's 2007-06-07 change worked around this bug, but
12522 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12524 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12526 * xdisp.c (start_display): If the character at POS is displayed
12527 via a display vector, reset IT->current.dpvec_index to zero.
12528 (try_window_reusing_current_matrix): If a line ends in a display
12529 vector or the next line starts in a display vector, continue
12530 redrawing the window even though the character position of
12531 start_row was reached.
12534 2011-10-18 Chong Yidong <cyd@gnu.org>
12536 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12537 with nobreak-char-display too.
12539 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12541 Fix part 3 of bug#9771.
12542 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12543 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12544 non-neutral characters if the current character is a paragraph
12545 separator (a.k.a. Newline). This avoids running the same
12546 expensive loop twice, once when we consume the preceding newline
12547 and the other time when the line actually needs to be displayed.
12548 Avoid the loop when we see neutrals on the base embedding level
12549 following a character whose directionality is the same as the
12550 paragraph's. This avoids running the expensive loop when a line
12551 ends in a long sequence of neutrals, like control characters.
12552 Add assertion against STRONG_AL type. Slightly rearrange code
12553 that determines the type of a neutral given the first non-neutral
12555 (bidi_level_of_next_char): Set next_en_pos to zero when
12556 invalidating its info.
12558 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12560 * xdisp.c (push_display_prop): Determine whether to record string
12561 or buffer position by IT->string, not by IT->method. Allow
12562 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12563 (move_it_vertically_backward): Don't look for character position
12564 immediately after the newline when in a continuation line.
12567 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12569 * window.c (coordinates_in_window): Rewrite and delabelize
12570 vertical border check. (Bug#5357) (Bug#9618)
12572 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12574 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12575 errors in XSetWindowBorder (bug#9310).
12577 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12579 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12580 avoid crash when xmalloc overrun checking is enabled.
12582 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12584 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12585 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12586 cursor motion with <left> and <right> arrow keys.
12588 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12589 some callers set that themselves.
12591 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12593 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12594 display string and the previous row comes from the same string and
12595 is empty. (Bug#9739) (Bug#9738)
12597 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12599 * doc.c (get_doc_string): Encode file name (bug#9735).
12601 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12603 * bidi.c (bidi_level_of_next_char):
12604 * xdisp.c (get_visually_first_element): Remove old incorrect
12605 comments regarding the Unicode Line Separator character.
12607 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12609 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12611 * alloc.c (Fgc_status): Do not access beyond zombies array
12612 boundary if nzombies > MAX_ZOMBIES.
12613 * alloc.c (dump_zombies): Add missing format specifier.
12615 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12617 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12618 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12620 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12621 Some packages use them to denote characters with modifiers.
12623 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12625 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12626 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12627 matching a pp-number. Rename parameter var to var1.
12629 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12631 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12633 2011-10-08 Glenn Morris <rgm@gnu.org>
12635 * callint.c (Fcall_interactively): Give a more explicit error for the
12636 'c' case with a non-character input. (Bug#8479)
12638 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12640 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12642 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12643 lines that are hscrolled on the left.
12645 * dispnew.c (buffer_posn_from_coords): Account for a possible
12646 presence of header-line. (Bug#4426)
12648 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12650 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12651 Don't advertise functionality which we discourage or doesn't work.
12653 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12655 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12656 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12657 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12658 this makes Emacs dump core during garbage collection on rare
12659 occasions. sizeof is obviously inferior to offsetof here, so
12660 stick with offsetof.
12661 (GC_POINTER_ALIGNMENT): New macro.
12662 (mark_memory): Omit 3rd (offset) arg; caller changed.
12663 Don't assume EMACS_INT alignment is the same as pointer alignment.
12665 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12667 * keyboard.c (read_key_sequence_remapped): New var.
12668 (read_key_sequence): Compute remapping in the right buffer.
12669 (command_loop_1): Use read_key_sequence's remapping directly.
12671 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12673 * dired.c (file_name_completion): Don't expand file name.
12674 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12675 before checking file name handler.
12677 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12678 they've been requested explicitly (bug#9591).
12680 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12682 * keymap.c (Fsingle_key_description): Use make_specified_string
12683 instead of build_string to build string from push_key_description.
12686 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12688 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12689 This fixes a Y2038 bug on 64-bit hosts.
12690 * buffer.c (reset_buffer):
12691 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12692 (Fclear_buffer_auto_save_failure):
12693 Use 0, not -1, to represent an unset failure time, since time_t
12694 might not be signed.
12696 Remove dependency on glibc malloc internals.
12697 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12698 Move back here from lisp.h, but with their new implementations.
12699 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12700 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12701 * charset.c (charset_table_init): New static var.
12702 (syms_of_charset): Use it instead of xmalloc. This removes a
12703 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12704 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12705 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12706 Move back to alloc.c.
12707 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12708 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12710 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12712 * nsterm.m (windowDidResize): Call x_set_window_size only when
12713 ns_in_resize is true. Otherwise set pixelwidth/height and
12714 call change_frame_size (Bug#9628).
12716 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12718 Port --enable-checking=all to Fedora 14 x86-64.
12719 * charset.c (syms_of_charset): Also account for glibc malloc's
12720 internal overhead when calculating the initial malloc maximum.
12722 Port --enable-checking=all to Fedora 14 x86.
12723 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12725 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12726 (overrun_check_realloc, overrun_check_free):
12727 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12728 That way, xmalloc returns a properly-aligned pointer even if
12729 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12730 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12731 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12732 into account when calculating the initial malloc maximum.
12733 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12734 Move here from alloc.c, so that charset.c can use it too.
12735 Properly align; the old code wasn't right for common 32-bit hosts
12736 when configured with --enable-checking=all.
12737 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12738 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12740 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12742 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12745 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12747 * xdisp.c (compute_display_string_end): If there's no display
12748 string at CHARPOS, return -1.
12750 * bidi.c (bidi_fetch_char): When compute_display_string_end
12751 returns a negative value, treat the character as a normal
12752 character not covered by a display string. (Bug#9624)
12754 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12756 * lread.c (Fread_from_string): Fix typo in docstring.
12758 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12760 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12761 newline, reseat the iterator instead of bidi-iterating there one
12762 character at a time. (Bug#9610)
12763 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12764 TO_CHARPOS if the bidi iterator is at base embedding level.
12766 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12768 * lread.c (readevalloop): Use correct code for NBSP.
12769 (read1): Likewise. (Bug#9608)
12771 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12773 * dbusbind.c (Fdbus_register_signal): When service is not
12774 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12776 2011-09-25 Glenn Morris <rgm@gnu.org>
12778 * buffer.c (truncate-lines): Doc fix.
12780 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12782 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12783 (Fset_window_next_buffers): Doc fix.
12785 2011-09-24 Glenn Morris <rgm@gnu.org>
12787 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12789 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12791 Fix minor problems found by static checking.
12792 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12793 * indent.c (Fvertical_motion): Fix == vs = typo.
12795 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12797 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12798 Default value is now t. Doc fix.
12800 * indent.c (Fvertical_motion): Compute and apply the overshoot
12801 logic when moving up, not only when moving down. Fix the
12802 confusing name and values of the it_overshoot_expected variable;
12803 logic changes accordingly. (Bug#9254) (Bug#9549)
12805 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12806 CHARPOS is covered by a display string which includes newlines.
12807 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12808 is covered by a display string with embedded newlines.
12810 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12812 * dbusbind.c (Fdbus_register_signal): Add match rule to
12813 Vdbus_registered_objects_table. (Bug#9581)
12814 (Fdbus_register_method, Vdbus_registered_objects_table):
12817 2011-09-24 Jim Meyering <meyering@redhat.com>
12819 do not ignore write error for any output size
12820 The previous change was incomplete.
12821 While it makes emacs --batch detect the vast majority of stdout
12822 write failures, errors were still ignored whenever the output size is
12823 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12824 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12825 && echo FAIL: ignored write error
12826 FAIL: ignored write error
12827 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12828 && echo FAIL: ignored write error
12829 FAIL: ignored write error
12830 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12832 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12834 * emacs.c (Fkill_emacs): In noninteractive mode exit
12835 non-successfully if a write error occurred on stdout. (Bug#9574)
12837 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12839 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12842 * dispextern.h (struct it): Update the comment documenting what
12845 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12847 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12848 a display string, extend search for cursor position to end of row.
12849 (find_row_edges): If the row ends in a newline from a display
12850 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12851 Handle the case of a display string with multiple newlines.
12852 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12853 non-empty line. Fixes confusing cursor motion with arrow keys at
12854 the beginning of a line that starts with whitespace.
12856 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12858 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12861 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12863 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12864 boolean (Bug#9154).
12866 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12868 * xdisp.c (display_line): Record maximum and minimum buffer
12869 positions even if no glyphs were produced (e.g., by a zero-width
12870 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12871 buffer positions that will be removed from the glyph row because
12873 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12874 column is beyond frame width: don't subtract 1 "pixel" when
12875 computing width of the stretch.
12876 (reseat_at_next_visible_line_start): Undo the change made on
12877 2011-09-17 that saved paragraph information and restored it after
12878 the call to `reseat'. (Bug#9545)
12880 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12882 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12883 and turn window cursor on if cleared (Bug#9415).
12885 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12887 * search.c (boyer_moore): Take unibyte characters from pattern
12888 literally. (Bug#9458)
12890 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12892 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12894 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12896 Fix minor problem found by static checking.
12897 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12898 initialized, to pacify gcc -Wuninitialized.
12900 * fileio.c: Report proper errno when syscall falls.
12901 (Finsert_file_contents): Save and restore errno,
12902 so that report_file_error outputs the correct diagnostic.
12903 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12905 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12907 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12909 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12911 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12912 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12914 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12916 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12917 about the current paragraph and restore it after the call to reseat.
12919 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12920 (bidi_find_paragraph_start): Search back for paragraph beginning
12921 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12922 (bidi_move_to_visually_next): Only trigger paragraph-related
12923 computations when the last character is a newline or at EOB, not
12924 just any NEUTRAL_B. (Bug#9470)
12926 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12927 truncated lines if point is covered by a display string. (Bug#9524)
12929 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12931 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12932 (cons_to_x_long): New function.
12933 (lisp_data_to_selection_data): Use it. Correct the test for
12934 short-versus-long data; it was negated. Break out of vector
12935 loop, for efficiency, when a long datum is discovered.
12937 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12939 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12941 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12943 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12944 GCC PR/17406) by declaring this function with external scope.
12946 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12948 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

12953 * editfns.c (Fformat): Correctly handle text properties on "%%".
12955 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12957 * xterm.c (x_draw_composite_glyph_string_foreground):
12958 * w32term.c (x_draw_composite_glyph_string_foreground):
12959 * term.c (encode_terminal_code):
12960 * composite.c (composition_update_it, get_composition_id):
12961 * xdisp.c (get_next_display_element)
12962 (fill_composite_glyph_string): Add comments about special meaning
12963 of TAB characters in a composition.
12965 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12967 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12968 This occurs when processing a multibyte format.
12969 Problem reported by Wolfgang Jenker.
12971 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12973 * xdisp.c (try_cursor_movement): Only check for exact match if
12974 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12976 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12978 Remove unused external symbols.
12979 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12980 * xdisp.c (calc_pixel_width_or_height): Now static.
12981 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12982 * indent.c (check_display_width):
12983 * w32term.c: Fix comment to match code.
12984 * xterm.c, xterm.h (x_catching_errors): Remove.
12986 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12988 * xselect.c: Use signed conversions more consistently (Bug#9498).
12989 (selection_data_to_lisp_data): Assume incoming selection data are
12990 signed integers, not unsigned. This is to be consistent with
12991 outgoing selection data, which was modified to use signed integers
12992 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12993 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12994 expects long, not unsigned long.
12996 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12998 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12999 computation of loop end. Reported by Johan Bockgård
13002 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13004 * frame.c (Fother_visible_frames_p): Function deleted.
13006 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13008 * indent.c (compute_motion): Process display vector front to back
13009 rather than the other way around. (Bug#2496)
13011 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13013 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13015 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13017 * minibuf.c (Fread_from_minibuffer): Doc fix.
13019 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13021 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13022 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13024 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13026 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13027 value for non-existent files.
13029 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13031 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13032 set its "size" to -1. This will set the modtime_size field of
13033 the corresponding buffer to -1, which is what
13034 verify-visited-file-modtime expects for files that do not exist.
13037 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13039 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13041 * lisp.h: ... from here. push_key_description is no longer
13042 defined in keyboard.c, so its declaration should not be in
13043 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13044 logically belongs with push_key_description.
13046 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13048 * buffer.h: Include <sys/types.h> instead of <time.h>.
13049 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13050 Problem reported by Herbert J. Skuhra.
13052 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13054 * xml.c (parse_region): Make the parsing work for
13055 non-comment-starting XML files again (bug#9144).
13057 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13059 * image.c (gif_load): Fix calculation of bottom and right corner.
13062 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13064 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13065 redisplay in small windows.
13067 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13069 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13071 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13073 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13074 Operate on live windows only.
13076 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13078 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13080 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13082 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13083 only under bidi iteration.
13085 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13087 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13089 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13091 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13092 Without this fix, the command to link temacs failed due to an
13093 undefined symbol __builtin_isnan. This is because
13094 /usr/include/iso/math_c99.h #defines isnan(x) to
13095 __builtin_isnan(x), but the bundled gcc, which identifies itself
13096 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13098 * floatfns.c (isnan): #undef, and then #define to a clone of
13100 (Fisnan): Always define, since it's always available now.
13101 (syms_of_floatfns): Always define isnan at the Lisp level.
13103 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13105 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13107 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13109 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13110 The previous code assumed that file offsets (off_t values) fit in
13111 EMACS_INT variables, which is not true on typical 32-bit hosts.
13112 The code messed up by falsely reporting buffer overflow in cases
13113 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13114 when "big" contains more than 2**29 bytes, even though this
13115 inserts just one byte and does not overflow the buffer.
13116 (Finsert_file_contents): Store file offsets as off_t
13117 values, not as EMACS_INT values. Check for overflow when
13118 converting between EMACS_INT and off_t. When checking for
13119 buffer overflow or for overlap, take the offsets into account.
13120 Don't use EMACS_INT for small values where int suffices.
13121 When checking for overlap, fix a typo: ZV was used where
13122 ZV_BYTE was intended.
13123 (Fwrite_region): Don't assume off_t fits into 'long'.
13124 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13126 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13128 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13130 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13132 sprintf-related integer and memory overflow issues (Bug#9412).
13134 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13135 (esprintf, exprintf, evxprintf): New functions.
13136 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13137 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13138 (modify_event_symbol): Do not assume that the length of
13139 name_alist_or_stem is safe to alloca and fits in int.
13140 (Fexecute_extended_command): Likewise for function name and binding.
13141 (Frecursion_depth): Wrap around reliably on integer overflow.
13142 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13143 since some callers pass EMACS_INT values.
13144 (Fsingle_key_description): Don't crash if symbol name contains more
13145 than MAX_ALLOCA bytes.
13146 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13147 (get_minibuffer): Arg is now EMACS_INT, not int.
13148 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13149 (esprintf, exprintf, evxprintf): New decls.
13150 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13152 * dbusbind.c (signature_cat): New function.
13153 (xd_signature, Fdbus_register_signal):
13154 Do not overrun buffer; instead, report string overflow.
13156 * dispnew.c (add_window_display_history): Don't overrun buffer.
13157 Truncate instead; this is OK since it's just a log.
13159 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13160 even if the time zone offset is outlandishly large.
13161 Don't mishandle offset == INT_MIN.
13163 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13164 when creating daemon; the previous buffer-overflow check was incorrect.
13166 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13167 which has the guts of the old verror function.
13169 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13170 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13172 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13173 (font_unparse_xlfd): Don't blindly alloca long strings.
13174 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13175 fits in int, when using sprintf. Use single snprintf to count
13176 length of string rather than counting it via multiple sprintfs;
13177 that's simpler and more reliable.
13178 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13179 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13180 sprintf, in case result does not fit in int.
13182 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13183 (fontset_from_font): Print it.
13185 * frame.c (tty_frame_count): Now printmax_t, not int.
13186 (make_terminal_frame, set_term_frame_name): Print it.
13187 (x_report_frame_params): In X, window IDs are unsigned long,
13188 not signed long, so print them as unsigned.
13189 (validate_x_resource_name): Check for implausibly long names,
13190 and don't assume name length fits in 'int'.
13191 (x_get_resource_string): Don't blindly alloca invocation name;
13192 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13195 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13196 (xg_check_special_colors, xg_set_geometry):
13197 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13199 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13200 Use esprintf, not sprintf, in case result does not fit in int.
13202 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13203 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13204 it as a large positive number.
13205 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13206 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13208 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13209 in case result does not fit in int.
13211 * print.c (float_to_string): Detect width overflow more reliably.
13212 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13213 buffer overrun. Don't assume list length fits in 'int'. Treat
13214 print length of 0 as 0, not as infinity; to be consistent with other
13215 uses of print length in this function. Don't overflow print length
13216 index. Don't assume hash table size fits in 'long', or that
13217 vectorlike size fits in 'unsigned long'.
13219 * process.c (make_process): Use printmax_t, not int, to format
13220 process-name gensyms.
13222 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13224 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13225 to avoid potential buffer overrun.
13227 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13228 if X resource line is longer than 512 bytes.
13230 * xfns.c (x_window): Make sprintf buffer a bit bigger
13231 to avoid potential buffer overrun.
13233 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13235 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13237 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13239 Integer overflow fixes for scrolling, etc.
13240 Without these, Emacs silently mishandles large integers sometimes.
13241 For example, "C-u 4294967297 M-x recenter" was treated as if
13242 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13244 * xdisp.c (try_window_id): Check Emacs fixnum range before
13245 converting to 'int'.
13247 * window.c (window_scroll_line_based, Frecenter):
13248 Check that an Emacs fixnum is in range before assigning it to 'int'.
13249 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13250 values converted from Emacs fixnums.
13251 (Frecenter): Don't wrap around a line count if it is out of 'int'
13252 range; instead, treat it as an extreme value.
13253 (Fset_window_configuration, compare_window_configurations):
13254 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13256 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13257 that can exceed INT_MAX. Check that EMACS_INT value is in range
13258 before assigning it to the (possibly-narrower) index.
13259 (match_limit): Don't assume that a fixnum can fit in 'int'.
13261 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13264 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13265 (Fvertical_motion): Don't wrap around LINES values that don't fit
13266 in 'int'. Instead, treat them as extreme values. This is good
13267 enough for windows, which can't have more than INT_MAX lines anyway.
13269 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13271 * Require libxml/parser.h to avoid compilation warning.
13273 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13275 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13276 since this reportedly can destroy thread storage.
13278 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13280 * syntax.c (find_defun_start): Update all cache variables if
13281 exiting early (Bug#9401).
13283 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13285 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13287 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13288 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13289 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13291 * term.c (tty_append_glyph): New function.
13292 (produce_stretch_glyph): Static function and its prototype deleted.
13294 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13297 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13299 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13300 when checking :margin (Bug#9390).
13301 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13302 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13303 so that the name doesn't mislead. All uses changed.
13305 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13307 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13310 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13312 * xdisp.c (move_it_to): Don't bail out early when reaching
13313 position beyond to_charpos, if we are scanning backwards.
13314 (move_it_vertically_backward): When DY == 0, make sure we get to
13315 the first character in the line after the newline.
13317 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13319 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13320 (ccl_driver): Do not generate an out-of-range pointer.
13321 (Fccl_execute_on_string): Remove unnecessary check for
13322 integer overflow, noted by Stefan Monnier in
13323 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13324 Remove a FIXME that didn't need fixing.
13325 Simplify the newly-introduced buffer reallocation code.
13327 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13329 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13331 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13333 Integer and memory overflow issues (Bug#9196).
13335 * doc.c (get_doc_string): Rework so that
13336 get_doc_string_buffer_size is the actual buffer size, rather than
13337 being 1 less than the actual buffer size; this makes xpalloc more
13340 * image.c (x_allocate_bitmap_record, cache_image):
13341 * xselect.c (Fx_register_dnd_atom):
13342 Simplify previous changes by using xpalloc.
13344 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13345 since either will do and ptrdiff_t is convenient with xpalloc.
13347 * charset.c (charset_table_size)
13348 (struct charset_sort_data.priority): Now ptrdiff_t.
13349 (charset_compare): Don't overflow if priorities differ greatly.
13350 (Fsort_charsets): Don't assume list length fits in int.
13351 Check for size-calculation overflow when allocating sort data.
13352 (syms_of_charset): Allocate an initial charset table that is
13353 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13355 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13357 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13358 The actual value is always <= INT_MAX, and leaving it unsigned made
13359 overflow checking harder.
13361 * dispextern.h (struct glyph_matrix.rows_allocated)
13362 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13363 with xpalloc. The values are still always <= INT_MAX.
13365 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13367 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13368 (SAFE_NALLOCA): New macro.
13370 * region-cache.c (struct boundary.pos, find_cache_boundary)
13371 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13372 (set_cache_region, invalidate_region_cache)
13373 (revalidate_region_cache, know_region_cache, region_cache_forward)
13374 (region_cache_backward, pp_cache):
13375 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13376 so that ptrdiff_t * can be passed to xpalloc.
13377 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13378 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13379 (pp_cache): Don't assume cache_len fits in int.
13380 * region-cache.h: Adjust extern decls to match.
13382 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13383 EMACS_INT, since either will do, for xpalloc.
13385 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13386 (xnmalloc, xnrealloc, xpalloc): New functions.
13388 * bidi.c (bidi_shelve_header_size): New constant.
13389 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13390 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13392 * bidi.c (bidi_cache_shrink):
13393 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13395 Don't update size of array until after memory allocation succeeds,
13396 because xmalloc/xrealloc may not return.
13397 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13398 now that we have proper integer overflow checking.
13399 (record_overlay_string, overlay_strings): Catch overflows when
13400 calculating size of overlay_str_buf.
13402 * callproc.c (Fcall_process): Check for size overflow when
13403 calculating size of args2.
13404 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13405 Normally we prefer signed values, but sticking with ptrdiff_t would
13406 require adding more-complicated checks.
13408 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13409 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13410 Redo buffer-overflow calculations to avoid integer overflow.

13449 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13451 * emacs.c (main): Do not reallocate argv, since there is a null at
13452 the end that can be overwritten, and this way there's no need to
13453 worry about size-calculation overflow.
13454 (sort_args): Check for size-calculation overflow.

13463 (x_set_alpha): Do not assume XINT fits in int.
13465 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13466 This is for the members text_lines, text_cols, total_lines, total_cols,
13467 where the system imposes an 'int' limit.

13571 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13572 sizes, since they can exceed INT_MAX in size. Check for size

13582 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13583 (X_LONG_MIN): New macros.
13584 Use them to make the following changes clearer.
13585 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13586 This change doesn't affect the value now, but it may help remind
13587 future maintainers not to raise the value too much later.
13588 (SELECTION_QUANTUM): Remove, replacing with ...
13589 (selection_quantum): ... new function, which avoids overflow.
13591 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13592 assumption that selection length fits in 'int'.

13609 Don't store size until memory allocation succeeds.
13610 (x_get_window_property): Plug memory leak on memory exhaustion.
13611 Don't double-block input; malloc is safe here. Don't assume 2**34
13612 - 4 fits in unsigned long. Add an xassert to check
13613 XGetWindowProperty overflow. Be more careful about overflow
13614 calculations, and distinguish size from memory overflow better.
13615 (receive_incremental_selection): When tracing, don't assume
13616 unsigned int is less than INT_MAX.
13617 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

13620 in the range -65535 through -1 fit in an X unsigned short.
13621 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13622 result parameters unless successful. Rely on cons_to_unsigned
13623 to report problems with elements; the old code wasn't right anyway.
13624 (x_check_property_data): Check for int overflow; we cannot use
13625 a wider type due to X limits.

13658 * lisp.h (hash_lookup, hash_put):
13659 * minibuf.c (Ftest_completion):
13660 Use ptrdiff_t for hash table indexes, not int (which is too
13661 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
13662 32-bit --with-wide-int hosts).
13664 * charset.c (Fdefine_charset_internal): Check for integer overflow.
13665 Add a FIXME comment about memory leaks.

13673 with outlandish widths.
13674 * character.h (sanitize_tab_width): Rename from sanitize_width,
13675 now that we have two such functions. All uses changed.

13693 * xterm.c: Don't go over XClientMessageEvent limit.
13694 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
13695 (x_send_scroll_bar_event): Likewise. Check that the size does not
13696 exceed limits imposed by XClientMessageEvent, as well as the usual
13697 ptrdiff_t and size_t limits.
13699 * keyboard.c: Overflow, signedness and related fixes.
13700 (make_lispy_movement): Use same integer type in forward decl
13701 that is used in the definition.
13702 (read_key_sequence, keyremap_step):
13703 Change bufsize argument back to int, undoing my 2011-03-30 change.
13704 We prefer signed types, and int is wide enough here.
13705 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13706 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13707 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13708 length, not size_t. Use ptrdiff_t for index, not int.
13709 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13710 possibility of integer overflow.

13738 Prefer int to unsigned where either will do.
13739 (tiff_handler): New function, combining the cores of the
13740 old tiff_error_handler and tiff_warning_handler.
13741 This function is rewritten to use vsnprintf and thereby avoid
13742 stack buffer overflows. It uses only the features of vsnprintf
13743 that are common to both POSIX and native Microsoft.
13744 (tiff_error_handler, tiff_warning_handler): Use it.
13745 (tiff_load, gif_load, imagemagick_load_image):
13746 Don't assume :index value fits in 'int'.
13747 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
13748 (imagemagick_load_image): Check that crop parameters fit into
13749 the integer types that MagickCropImage accepts. Don't assume
13750 Vimagemagick_render_type has a nonnegative value. Don't assume
13751 size_t fits in 'long'.
13752 (gs_load): Use printmax_t to print the widest integers possible.

13765 handle_single_display_spec, not just 1 or zero.
13766 (handle_single_display_spec): If the display spec is of the form
13767 `(space ...)', and specifies display in the text area, return 2
13769 (try_cursor_movement): Check for the need to scroll more
13770 accurately, and prefer exact match for point under bidi.
13771 Don't advance `row' beyond the last row of the window.

13789 buffers, return left-to-right.
13790 (set_cursor_from_row): Consider candidate row a win if its glyph
13791 represents a newline and point is on that newline. Fixes cursor
13792 positioning on the newline at EOL of R2L text within L2R
13793 paragraph, and vice versa.
13794 (try_cursor_movement): Check continued rows, in addition to
13795 continuation rows. Fixes unwarranted scroll when point enters a
13796 continued line of R2L text within an L2R paragraph, or vice versa.
13797 (cursor_row_p): Consider the case of point being equal to
13798 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13799 from the end of a short line to the beginning of a continued line
13800 of R2L text within L2R paragraph.
13801 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

13824 * xdisp.c (redisplay_window): When computing centering_position,
13825 account for the height of the header line. (Bug#8874)
13827 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13828 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13829 candidate is selected by the mouse, and that candidate has a
13830 composed character under the mouse.
13832 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13833 coordinates reported by pos-visible-in-window-p for a composed
13834 character in column zero.

13844 composed buffer positions.
13846 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13848 * image.c (gif_load): Don't assume that each subimage has the same
13849 dimensions as the base image. Handle disposal method that is
13850 "undefined" by the gif spec (Bug#9335).
13852 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13854 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

13860 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13861 from an Org mode buffer to a Speedbar frame.
13863 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13864 a composition, take its buffer position from IT->cmp_it.charpos.
13865 Fixes cursor positioning at the beginning of a line that begins
13866 with a composed character.
13868 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13870 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13871 character bidirectional type, use STRONG_L instead. Fixes crashes
13872 in a buffer produced by `describe-categories'.
13874 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13875 members before the level stack, so they would be saved and
13876 restored when copying iterator state. Fixes incorrect reordering
13877 around TABs covered by display properties.
13879 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
13881 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

13887 Remove unnecessary aborts (Bug#9081).
13889 2011-08-17 Eli Zaretskii <eliz@gnu.org>
13891 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
13892 has no `load' handler, try opening the file locally. (Bug#9311)
13894 2011-08-16 Ken Brown <kbrown@cornell.edu>
13896 * gmalloc.c: Expand comment.
13898 2011-08-16 Eli Zaretskii <eliz@gnu.org>

13951 * xdisp.c (move_it_in_display_line_to): Don't invoke
13952 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13953 ppos_it. Fixes vertical cursor motion when line beginning is
13954 covered by an image. (Bug#9296)
13956 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
13958 * nsterm.h (ns_run_ascript): Declare.

13961 * nsfns.m (as_script, as_result, as_status): New static variables.
13962 (ns_run_ascript): New function.
13963 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
13964 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13965 the event loop. Get status from as_status (Bug#7276).
13967 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13968 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13969 the event loop (Bug#7276).
13971 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13973 * gnutls.c (QCgnutls_bootprop_priority)

13995 (Fnetwork_interface_list): Allocate in increments of bytes instead
13996 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13997 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13999 (struct ifflag_def): notrailers is smart on OSX.
14000 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14001 Get hardware address with getifaddrs if available.
14003 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14005 * xdisp.c (iterate_out_of_display_property): xassert that
14006 IT->position is set to within IT->object's boundaries. Break from
14007 the loop as soon as EOB is reached; avoids infloops in redisplay
14008 when IT->position is set up wrongly due to some bug.
14009 Set IT->current to match the bidi iterator unconditionally.
14010 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14011 entry. Force push_it to save on the stack the current
14012 buffer/string position, to be restored by pop_it. Fix flags in
14013 the iterator structure wrt the object coming from a display
14014 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14015 properties. (Bug#9284)
14017 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14019 * fontset.c (fontset_get_font_group): Add proper type checks.

14032 no-display-properties-and-no-overlays under bidi display.
14033 Set disp_pos in the bidi iterator to avoid searches for display
14034 properties and overlays.
14036 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14038 * editfns.c (Fset_time_zone_rule): Document relationship with the

14047 restore_point_unwind (Bug#5984).
14049 2011-08-07 Juri Linkov <juri@jurta.org>
14051 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14052 to show the arg `TIME' instead of `TIMEVAL'.
14054 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14056 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14057 display property strides EOL and includes a newline, as in
14058 longlines-mode. (Bug#9254)
14059 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14060 word-wrap under bidirectional display. (Bug#9224)
14062 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14063 is non-zero, even if the data buffer is NULL. Fixes a crash in
14064 vertical-motion with longlines-mode. (Bug#9254)
14066 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14068 * bidi.c <bidi_cache_total_alloc>: Now static.
14069 (bidi_initialize): Initialize bidi_cache_total_alloc.
14071 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14074 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14075 amount allocated this far in `bidi_cache_total_alloc'.
14076 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14077 non-zero, only free the data buffer without restoring the cache
14078 contents. All callers changed.
14080 * dispextern.h (bidi_unshelve_cache): Update prototype.
14082 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14083 (move_it_in_display_line, move_it_to)
14084 (move_it_vertically_backward, move_it_by_lines): Replace the call
14085 to xfree to an equivalent call to bidi_unshelve_cache.
14086 (move_it_in_display_line_to): Fix logic of returning
14087 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14089 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14091 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14092 came from a string character with a `cursor' property. (Bug#9229)
14094 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14096 * Makefile.in (LIB_PTHREAD): New variable.
14097 (LIBES): Add LIB_PTHREAD (Bug#9216).
14099 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14100 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14102 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14104 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14106 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14108 * xterm.c (x_find_topmost_parent): New function.
14109 (x_set_frame_alpha): Find topmost parent window with
14110 x_find_topmost_parent and set the property there also (bug#9181).
14111 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14113 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

14124 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14125 so that it is not optimized away.
14127 * xdisp.c (compute_display_string_pos): Remove unused local.
14129 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14131 Fix slow cursor motion and scrolling in large buffers with
14132 selective display, like Org Mode buffers. (Bug#9218)
14134 * dispextern.h (struct bidi_it): New member disp_prop_p.
14136 * xdisp.c: Remove one-slot cache of display string positions.
14137 (compute_display_string_pos): Accept an additional argument
14138 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14139 for a display string or property. If found, set DISP_PROP_P
14142 * bidi.c (bidi_fetch_char): Accept an additional argument
14143 DISP_PROP_P, and pass it to compute_display_string_pos.
14144 Only handle text covered by a display string if DISP_PROP_P is returned
14145 non-zero. All callers of bidi_fetch_char changed.
14147 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14149 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14151 2010-12-03 Don March <don@ohspite.net>
14153 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14154 last character M-[char] is translated to ESC [char] (bug#7541).
14156 2011-08-02 Kenichi Handa <handa@m17n.org>
14158 * lisp.h (uniprop_table): Extern it.
14160 * chartab.c (uniprop_table): Make it non-static.
14162 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14164 * xdisp.c (forward_to_next_line_start): Accept additional argument
14165 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14167 (reseat_at_next_visible_line_start): Use the bidi iterator state
14168 returned by forward_to_next_line_start to restore the state of
14169 it->bidi_it after backing up to previous newline. (Bug#9212)
14171 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14173 * regex.c (re_comp): Protoize.
14174 (re_exec): Fix return type.
14175 (regexec): Fix type of `ret'. (Bug#9203)
14177 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14179 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14180 This is needed if max-image-size is a floating-point number.
14182 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14184 * print.c (print_object): Print empty symbol as ##.

14190 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14191 setting frame foreground color (Bug#9175).
14192 (x_set_background_color): Likewise.
14194 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14195 contents (Bug#9176).
14196 (EmacsTooltip -init): Remove bezels and add shadows to
14199 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14200 or scroll bar (Bug#8470).
14202 * nsfont.m (nsfont_open): Remove assignment to voffset and
14203 unnecessary vars hshink, expand, hd, full_height, min_height.
14204 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14206 * nsterm.h (nsfont_info): Remove voffset field.
14208 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14210 Implement strike-through and overline on NextStep (Bug#8863).
14212 * nsfont.m (nsfont_open): Use underline position provided by font,
14213 instead of hard-coded value of 2.
14214 (nsfont_draw): Call ns_draw_text_decoration instead.

14222 accommodate underlining, etc.
14224 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14226 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14229 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14231 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14232 Without this fix, if a signal arrives just after memory fills up,
14233 'malloc' might be invoked reentrantly.
14235 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14236 In other words, assume that every image size is allowed, on non-X
14237 hosts. This assumption is probably wrong, but it lets Emacs compile.
14239 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14241 * regex.c (re_iswctype): Convert return values to boolean.
14243 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14245 * xdisp.c (compute_display_string_pos): Don't use cached display
14246 string position if the buffer had its restriction changed.
14249 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14251 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14253 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14255 Integer signedness and overflow and related fixes. (Bug#9079)
14257 * bidi.c: Integer size and overflow fixes.
14258 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14259 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14260 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14261 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14262 (bidi_find_other_level_edge):
14263 Use ptrdiff_t instead of EMACS_INT where either will do.
14264 This works better on 32-bit hosts configured --with-wide-int.
14265 (bidi_cache_ensure_space): Check for size-calculation overflow.
14266 Use % rather than repeated addition, for better worst-case speed.
14267 Don't set bidi_cache_size until after xrealloc returns, because it
14269 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14270 (bidi_cache_ensure_space): Also check that the bidi cache size
14271 does not exceed that of the largest Lisp string or buffer. See Eli
14272 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14274 * alloc.c (__malloc_size_t): Remove.
14275 All uses replaced by size_t. See Andreas Schwab's note
14276 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14278 * image.c: Improve checking for integer overflow.
14279 (check_image_size): Assume that f is nonnull, since
14280 it is always nonnull in practice. This is one less thing to
14281 worry about when checking for integer overflow later.
14282 (x_check_image_size): New function, which checks for integer
14283 overflow issues inside X.
14284 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14285 This removes the need for a memory_full check.
14286 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14287 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14288 (xbm_read_bitmap_data): Change locals back to 'int', since
14289 their values must fit in 'int'.
14290 (xpm_load_image, png_load, tiff_load):
14291 Invoke x_create_x_image_and_pixmap earlier,
14292 to avoid much needless work if the image is too large.
14293 (tiff_load): Treat overly large images as if
14294 x_create_x_image_and_pixmap failed, not as malloc failures.
14295 (gs_load): Use x_check_image_size.
14297 * gtkutil.c: Omit integer casts.
14298 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14299 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14301 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14303 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14304 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14305 would wrongly return t on a 64-bit host.
14307 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14308 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14309 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14310 and therefore cause GCC to emit a bogus diagnostic in some cases.
14312 * image.c: Integer signedness and overflow and related fixes.
14313 This is not an exhaustive set of fixes, but it's time to
14314 record what I've got.
14315 (lookup_pixel_color, check_image_size): Remove redundant decls.
14316 (check_image_size): Don't assume that arbitrary EMACS_INT values
14317 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14318 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14319 (tiff_load, imagemagick_load_image):
14320 Check for overflow in size calculations.
14321 (x_create_x_image_and_pixmap): Remove unnecessary test for
14322 xmalloc returning NULL; that can't happen.
14323 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14324 (xpm_color_bucket): Use better integer hashing function.
14325 (xpm_cache_color): Don't possibly over-allocate memory.
14326 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14327 (gif_memory_source):
14328 Use ptrdiff_t, not int or size_t, to record sizes.
14329 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14330 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14331 either works, as we prefer signed integers.
14332 (tiff_read_from_memory, tiff_write_from_memory):
14333 Return tsize_t, not size_t, since that's what the TIFF API wants.
14334 (tiff_read_from_memory): Don't fail simply because the read would
14335 go past EOF; instead, return a short read.
14336 (tiff_load): Omit no-longer-needed casts.
14337 (Fimagemagick_types): Don't assume size fits into 'int'.
14339 Improve hashing quality when configured --with-wide-int.
14340 * fns.c (hash_string): New function, taken from sxhash_string.
14341 Do not discard information about ASCII character case; this
14342 discarding is no longer needed.
14343 (sxhash-string): Use it. Change sig to match it. Caller changed.
14344 * lisp.h: Declare it.
14345 * lread.c (hash_string): Remove, since we now use fns.c's version.
14346 The fns.c version returns a wider integer if --with-wide-int is
14347 specified, so this should help the quality of the hashing a bit.
14349 * emacs.c: Integer overflow minor fix.
14350 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14351 Define only if GNU_LINUX.
14352 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14354 * dispnew.c: Integer signedness and overflow fixes.
14355 Remove unnecessary forward decls, that were a maintenance hassle.
14356 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14358 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14359 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14360 (prepare_desired_row, line_draw_cost):
14361 Use int, not unsigned, where either works.
14362 (save_current_matrix, restore_current_matrix):
14363 Use ptrdiff_t, not size_t, where either works.
14364 (init_display): Check for overflow more accurately, and without
14365 relying on undefined behavior.
14367 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14368 Remove, replacing with the new symbols in lisp.h. All uses changed.
14369 * fileio.c (make_temp_name):
14370 * filelock.c (lock_file_1, lock_file):
14371 * xdisp.c (message_dolog):
14372 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14373 Use pMd etc. instead.
14374 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14375 replacing the pWIDE etc. symbols removed from editfns.c.
14377 * keyboard.h (num_input_events): Now uintmax_t.
14378 This is (very slightly) less likely to mess up due to wraparound.
14381 * buffer.c: Integer signedness fixes.
14382 (alloc_buffer_text, enlarge_buffer_text):
14383 Use ptrdiff_t rather than size_t when either will do, as we prefer
14386 * alloc.c: Integer signedness and overflow fixes.
14387 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14388 (__malloc_size_t): Default to size_t, not to int.
14389 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14390 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14391 Prefer ptrdiff_t to size_t when either would do, as we prefer
14393 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14394 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14395 Now const. Initialize with values that are in range even if char
14397 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14398 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14399 These functions do the right thing with sizes > 2**32.
14400 (check_depth): Now ptrdiff_t, not int.
14401 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14402 Adjust to new way of storing sizes. Check for size overflow bugs
14404 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14405 slightly wrong anyway, as it missed one instance of
14406 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14407 (refill_memory_reserve): Omit needless cast to size_t.
14408 (mark_object_loop_halt): Mark as externally visible.
14410 * xselect.c: Integer signedness and overflow fixes.
14411 (Fx_register_dnd_atom, x_handle_dnd_message):
14412 Use ptrdiff_t, not size_t, since we prefer signed.
14413 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14414 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14415 x_dnd_atoms_size and x_dnd_atoms_length.
14417 * doprnt.c: Prefer signed to unsigned when either works.
14419 * doprnt.c (doprnt):
14421 * xdisp.c (vmessage):
14422 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14423 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14424 prefer signed arithmetic to avoid comparison confusion.
14425 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14426 but is a bit tricky.
14428 Assume freestanding C89 headers, string.h, stdlib.h.
14429 * data.c, doprnt.c, floatfns.c, print.c:
14430 Include float.h unconditionally.
14431 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14432 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14433 * regex.c: Likewise for stddef.h, string.h.
14434 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14435 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14436 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14437 (STDC_HEADERS): Remove obsolete defines.
14438 * sysdep.c: Include limits.h unconditionally.
14440 Assume support for memcmp, memcpy, memmove, memset.
14441 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14442 * regex.c (memcmp, memcpy):
14443 Remove; we assume C89 now.
14445 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14446 (__malloc_safe_bcopy): Remove; no longer needed.
14448 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14449 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14450 well either way, and we prefer signed to unsigned.
14452 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14454 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14455 closes the connection while we're reading (bug#9182).
14457 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14459 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14460 are specified (Bug#9168).
14462 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14464 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14465 Found by GCC static checking and --with-wide-int on a 32-bit host.
14467 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14469 * xdisp.c (compute_display_string_pos): Fix logic of caching
14470 previous display string position. Initialize cached_prev_pos to
14471 -1. Fixes slow-down at the beginning of a buffer.
14473 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14475 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14476 for attrs[LFACE_FONTSET_INDEX].
14478 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14480 * xml.c (parse_region): Remove unused local
14481 that was recently introduced.
14483 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14485 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14486 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14488 * xdisp.c (move_it_in_display_line_to): Record the best matching
14489 position for TO_CHARPOS while scanning the line, and restore it on
14490 exit if none of the characters scanned was an exact match.
14491 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14492 when exact match is impossible due to invisible text, and the
14493 lines are truncated.
14495 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14497 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14500 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14502 Fix a significant slow-down of cursor motion with C-n, C-p,
14503 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14504 auto-repeat under bidi redisplay in fontified buffers.
14505 * xdisp.c (compute_stop_pos_backwards): New function.
14506 (next_element_from_buffer): Call compute_stop_pos_backwards to
14507 find a suitable prev_stop when we find ourselves before
14509 (reseat): Don't look for prev_stop, as that could mean a very long
14511 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14512 <cached_disp_overlay_modiff>: Cache for last found display string
14514 (compute_display_string_pos): Return the cached position if asked
14515 about the same buffer in the same area of character positions, and
14516 the buffer wasn't changed since the time the display string
14517 position was cached.
14519 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14521 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14522 is an integer, which is important for empty lines. (Bug#9149)
14524 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14526 * frame.c (Fmodify_frame_parameters): In tty case, update the
14527 default face if necessary (Bug#4238).
14529 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14531 * editfns.c (Fstring_to_char): No need to explain what a character
14532 is in the docstring (Bug#6576).
14534 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14536 * xml.c (parse_region): Make sure we always return a tree.
14538 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14540 * xml.c (parse_region): If a document contains only comments,
14543 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14545 * xml.c (make_dom): Return comments, too.
14547 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14550 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14551 and the surrounding thread.
14552 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14553 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14554 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14556 * s/openbsd.h (BROKEN_SIGIO): Define.
14557 * unexelf.c (unexec) [__OpenBSD__]:
14558 Don't update the .mdebug section of the Alpha COFF symbol table.
14560 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14562 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14565 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14567 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14568 This fixes some race conditions on the permissions of any newly
14571 * alloc.c (valid_pointer_p): Use pipe, not open.
14572 This fixes some permissions issues when debugging.
14574 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14575 If fchown fails to set both uid and gid, try to set just gid,
14576 as that is sometimes allowed. Adjust the file's mode to eliminate
14577 setuid or setgid bits that are inappropriate if fchown fails.
14579 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14581 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14582 to compare Lisp_Objects.
14583 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14584 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14585 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14587 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14589 * lread.c (read_integer): Unread even EOF character.
14590 (read1): Likewise. Properly record start position of symbol.
14592 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14593 symbol character follows.
14595 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14597 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14598 This works around a problem with the previous change to Fcopy_file.
14599 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14600 and without this change, GCC might complain about discarding
14601 fchown's return value.
14603 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14605 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14607 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14609 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14611 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14613 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14614 it's used from the C level.
14616 * process.c: Use the same condition for POLL_FOR_INPUT in both
14617 keyboard.c and process.c (bug#1858).
14619 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14621 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14622 (Fgnutls_boot): Use it.
14624 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14626 * doc.c (Fsubstitute_command_keys): Revert last change.
14628 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14630 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14631 quotes the next character, and doesn't affect other longer
14632 sequences (bug#8935).
14634 * lread.c (syms_of_lread): Clarify that is isn't only
14635 `eval-buffer' and `eval-defun' that's affected by
14636 `lexical-binding' (bug#8460).
14638 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14640 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14641 bidi redisplay when a line includes both an image and is truncated.
14643 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14645 Fix minor problems found by static checking.
14646 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14647 (elsz): Now a signed constant, not a size_t var. We prefer signed
14648 types to unsigned, to avoid integer comparison confusion. Without
14649 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14650 "cannot optimize loop, the loop counter may overflow", a symptom
14652 * indent.c (Fvertical_motion): Mark locals as initialized.
14653 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14655 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14657 * search.c (Fre_search_backward): Mention `case-fold-search' in
14658 all the re_search_* functions (bug#8138).
14660 * keyboard.c (Fopen_dribble_file): Document when the file is
14663 2011-07-14 Eli Zaretskii <eliz@gnu.org>
14665 * bidi.c (bidi_dump_cached_states): Fix format of displaying
14668 Support bidi reordering of display and overlay strings.
14669 * xdisp.c (compute_display_string_pos)
14670 (compute_display_string_end): Accept additional argument STRING.
14671 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
14672 (reseat_to_string): Initialize bidi_it->string.s and
14673 bidi_it->string.schars.
14674 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
14675 NULL (avoids a crash in bidi_paragraph_init).
14676 Initialize itb.string.lstring.
14677 (init_iterator): Call bidi_init_it only of a valid
14678 buffer position was specified. Initialize paragraph_embedding to
14680 (reseat_to_string): Initialize the bidi iterator.
14681 (display_string): If we need to ignore text properties of
14682 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14683 original value of -1 will not work with bidi.)
14684 (compute_display_string_pos): First arg is now struct
14685 `text_pos *'; all callers changed. Support display properties on
14687 (compute_display_string_end): Support display properties on Lisp
14689 (init_iterator, reseat_1, reseat_to_string): Initialize the
14690 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
14691 when iterating on a string not from display properties).
14692 (compute_display_string_pos, compute_display_string_end):
14693 Fix calculation of the object to scan. Fixes an error when using
14695 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
14696 base_level_stop; instead, set base_level_stop to BEGV.
14697 Fixes crashes in vertical-motion.
14698 (next_element_from_buffer): Improve commentary for when
14699 the iterator is before prev_stop.
14700 (init_iterator): Initialize bidi_p from the default value of
14701 bidi-display-reordering, not from buffer-local value. Use the
14702 buffer-local value only if initializing for buffer iteration.
14703 (handle_invisible_prop): Support invisible properties on strings
14704 that are being bidi-reordered.
14705 (set_iterator_to_next): Support bidi reordering of C strings and
14707 (next_element_from_string): Support bidi reordering of Lisp
14709 (handle_stop_backwards): Support Lisp strings as well.
14710 (display_string): Support display of R2L glyph rows.
14711 Use IT_STRING_CHARPOS when displaying from a Lisp string.
14712 (init_iterator): Don't initialize it->bidi_p for strings
14714 (reseat_to_string): Initialize it->bidi_p for strings here.
14715 (next_element_from_string, next_element_from_c_string)
14716 (next_element_from_buffer): Add xassert's for correspondence
14717 between IT's object being iterated and it->bidi_it.string
14719 (face_before_or_after_it_pos): Support bidi iteration.
14720 (next_element_from_c_string): Handle the case of the first string
14721 character that is not the first one in the visual order.
14722 (get_visually_first_element): New function, refactored from common
14723 parts of next_element_from_buffer, next_element_from_string, and
14724 next_element_from_c_string.
14725 (tool_bar_lines_needed, redisplay_tool_bar)
14726 (display_menu_bar): Force left-to-right direction. Add a FIXME
14727 comment for making that be controlled by a user option.
14728 (push_it, pop_it): Save and restore the state of the
14729 bidi iterator. Save and restore the bidi_p flag.
14730 (pop_it): Iterate out of display property for string iteration as
14732 (iterate_out_of_display_property): Support iteration over strings.
14733 (handle_single_display_spec): Set up it->bidi_it for iteration
14734 over a display string, and call bidi_init_it.
14735 (handle_single_display_spec, next_overlay_string)
14736 (get_overlay_strings_1, push_display_prop): Set up the bidi
14737 iterator for displaying display or overlay strings.
14738 (forward_to_next_line_start): Don't use the shortcut if
14740 (back_to_previous_visible_line_start): If handle_display_prop
14741 pushed the iterator stack, restore the internal state of the bidi
14742 iterator by calling bidi_pop_it same number of times.
14743 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
14744 and we are bidi-iterating, don't decrement the iterator position;
14745 instead, set the first_elt flag in the bidi iterator, to produce
14747 (reseat_1): Remove redundant setting of string_from_display_prop_p.

15216 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
15218 Random fixes. E.g., (random) never returned negative values.
15219 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15220 subseconds part to the entropy, as that's a bit more random.
15221 Prefer signed to unsigned, since the signedness doesn't matter and
15222 in general we prefer signed. When given a limit, use a
15223 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15224 latter isn't right if USE_2_TAGS_FOR_INTS.
15225 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15226 not 0..VALMASK. Don't discard "excess" bits that random () returns.
15228 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
15230 * textprop.c (text_property_stickiness):
15231 Obey Vtext_property_default_nonsticky.

15239 This is more efficient than Ffile_directory_p and avoids a minor race.
15241 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15243 * buffer.c (Foverlay_put): Say what the return value is
15246 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15247 is a directory before asking whether to use the file name
15249 (barf_or_query_if_file_exists): Make the "File is a directory"
15250 error be more correct.
15252 * fns.c (Frequire): Remove the mention of the .gz files, since
15253 that's installation-specific, but keep the mention of
15254 `get-load-suffixes'.
15256 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15258 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15264 (syms_of_gnutls): Remove duplicate DEFSYM for
15265 Qgnutls_bootprop_verify_hostname_error, an error for
15266 Qgnutls_bootprop_verify_error (which is no longer used).
15268 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15269 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15270 Also (re)move comments that are misplaced or no longer relevant.
15272 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15274 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15302 * fns.c (Frequire): Mention .el.gz files (bug#7314).
15303 (Frequire): Mention get-load-suffixes.

15333 (syms_of_keymap): Defsubr make-composed-keymap.
15334 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

15371 * eval.c (struct backtrace): Simplify and port the data structure.
15372 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15373 signed bit field, as this assumption is not portable and it makes
15374 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15375 "char debug_on_exit : 1" as this is not portable either; instead,
15376 use the portable "unsigned int debug_on_exit : 1". Remove unused
15377 member evalargs. Remove obsolete comments about cc bombing out.
15379 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
15381 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

15447 (emacs_fixed_new): Set priv->f to argument.
15448 (emacs_fixed_get_preferred_width)
15449 (emacs_fixed_get_preferred_height): Use min_width/height from
15450 frames size_hint to set minimum and natural (Bug#8919).
15451 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
15452 and use min_width/height from frames size_hint to set
15453 min_width/height (Bug#8919).

15473 Use gnulib's dup2 module instead of rolling our own.
15474 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

15545 * print.c (printchar, strout): Check for string overflow.
15546 (PRINTPREPARE, printchar, strout):
15547 Don't set size unless allocation succeeds.
15549 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
15550 for sizes. Check for string overflow more accurately.

15554 * keyboard.h (struct keyboard.kbd_macro_bufsize):
15555 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

15563 * lread.c: Integer overflow fixes.
15564 (read_integer): Radix is now EMACS_INT, not int,
15565 to improve quality of diagnostics for out-of-range radices.
15566 Calculate buffer size correctly for out-of-range radices.
15567 (read1): Check for integer overflow in radices, and in
15568 read-circle numbers.
15569 (read_escape): Avoid int overflow.
15570 (Fload, openp, read_buffer_size, read1)
15571 (substitute_object_recurse, read_vector, read_list, map_obarray):
15572 Use ptrdiff_t, not int, for sizes.
15573 (read1): Use EMACS_INT, not int, for sizes.
15574 Check for size overflow.
15576 * image.c (cache_image): Check for size arithmetic overflow.

15592 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15594 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15595 The following patches are for when GLYPH_DEBUG && !XASSERT.
15596 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15597 * dispnew.c (flush_stdout):
15598 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15599 Mark as externally visible.
15600 * dispnew.c (check_window_matrix_pointers): Now static.
15601 * dispnew.c (window_to_frame_vpos):
15602 * xfns.c (unwind_create_frame):
15603 * xterm.c (x_check_font): Remove unused local.

15605 * xfaces.c (cache_fache): Rename local to avoid shadowing.
15606 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.

15609 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
15611 (debug_method_add): Use va_list and vsprintf rather than relying
15612 on undefined behavior with wrong number of arguments.
15613 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15614 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15615 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15616 since we're not interested in debugging glyphs with old libraries.
15617 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15618 GCC 4.6.0's static checking.
15620 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15622 Integer overflow and signedness fixes (Bug#8873).
15623 A few related buffer overrun fixes, too.
15625 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
15627 * dispextern.h (struct face.stipple):

15631 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
15632 (x_create_bitmap_from_xpm_data):
15633 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
15634 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
15636 * xfaces.c (load_pixmap):
15637 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
15638 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
15639 (.bitmaps_last, struct x_output.icon_bitmap):
15640 Use ptrdiff_t, not int, for bitmap indexes.
15641 (x_allocate_bitmap_record): Check for size overflow.
15642 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
15644 Use ptrdiff_t, not int, for overlay counts.
15645 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
15646 * editfns.c (overlays_around, get_pos_property):
15647 * textprop.c (get_char_property_and_overlay):
15648 * xdisp.c (next_overlay_change, note_mouse_highlight):
15649 * xfaces.c (face_at_buffer_position):
15650 * buffer.c (OVERLAY_COUNT_MAX): New macro.
15651 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
15652 (Fnext_overlay_change, Fprevious_overlay_change)
15653 (mouse_face_overlay_overlaps, Foverlays_in):
15654 Use ptrdiff_t, not int, for sizes.
15655 (overlays_at, overlays_in): Check for size-calculation overflow.
15657 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
15659 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15660 (x_session_initialize): Do not assume string length fits in int.
15662 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15663 This is unlikely, but can occur if DPI is outlandish.
15665 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
15666 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
15668 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
15669 * xrdb.c (magic_file_p, search_magic_path):
15670 Omit last arg SUFFIX; it was always 0. All callers changed.
15671 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
15673 * xfont.c (xfont_match): Avoid need for strlen.
15675 * xfns.c: Don't assume strlen fits in int.
15676 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
15678 * xdisp.c (message_log_check_duplicate): Return intmax_t,
15679 not unsigned long, as we prefer signed integers. All callers changed.
15680 Detect integer overflow in repeat count.
15681 (message_dolog): Don't assume print length fits in 39 bytes.
15682 (display_mode_element): Don't assume strlen fits in int.
15684 * termcap.c: Don't assume sizes fit in int and never overflow.
15685 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
15686 (gobble_line): Check for size-calculation overflow.
15688 * minibuf.c (Fread_buffer):
15689 * lread.c (intern, intern_c_string):
15690 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
15691 Don't assume string length fits in int.
15693 * keyboard.c (parse_tool_bar_item):
15694 * gtkutil.c (style_changed_cb): Avoid need for strlen.
15696 * font.c: Don't assume string length fits in int.
15697 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
15698 Use ptrdiff_t, not int.
15699 (font_intern_prop): Don't assume string length fits in int.
15700 Don't assume integer property fits in fixnum.
15701 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
15703 * filelock.c: Fix some buffer overrun and integer overflow issues.
15704 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
15705 Reformulate so as not to need the command string.
15706 Invoke gzip -cd rather than gunzip, as it's more portable.
15707 (lock_info_type, lock_file_1, lock_file):
15708 Don't assume pid_t and time_t fit in unsigned long.
15709 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15710 (current_lock_owner): Prefer signed type for sizes.
15711 Use memcpy, not strncpy, where memcpy is what is really wanted.
15712 Don't assume (via atoi) that time_t and pid_t fit in int.
15713 Check for time_t and/or pid_t out of range, e.g., via a network share.
15714 Don't alloca where an auto var works fine.
15716 * fileio.c: Fix some integer overflow issues.
15717 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15718 Don't assume string length fits in int.
15719 (directory_file_name): Don't assume string length fits in long.
15720 (make_temp_name): Don't assume pid fits in int, or that its print
15721 length is less than 20.
15723 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15725 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15727 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15729 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15730 We prefer signed integers, even for size calculations.
15732 * emacs.c: Don't assume string length fits in 'int'.
15733 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15734 (main): Don't invoke strlen when not needed.
15736 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15737 (XD_DEBUG_MESSAGE): Don't waste a byte.
15739 * callproc.c (getenv_internal_1, getenv_internal)
15740 (Fgetenv_internal):
15741 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15743 * lread.c (invalid_syntax): Omit length argument.
15744 All uses changed. This doesn't fix a bug, but it simplifies the
15745 code away from its former Hollerith-constant appearance, and it's
15746 one less 'int' to worry about when looking at integer-overflow issues.
15747 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15749 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15750 This didn't break anything, but it didn't help either.
15751 It's confusing to put a bogus integer in a place where the actual
15752 value does not matter.
15753 (LIST_END_P): Remove unused macro and its bogus comment.
15754 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15756 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15757 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15759 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15760 We prefer signed types, and the value cannot exceed the EMACS_INT
15761 range anyway (because otherwise the length would not be representable).
15762 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15763 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15764 This avoids a GCC warning when WIDE_EMACS_INT.
15766 * indent.c (sane_tab_width): New function.
15767 (current_column, scan_for_column, Findent_to, position_indentation)
15768 (compute_motion): Use it. This is just for clarity.
15769 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15771 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15773 * lisp.h (lint_assume): New macro.
15774 * composite.c (composition_gstring_put_cache):
15775 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15777 * editfns.c, insdel.c:
15778 Omit unnecessary forward decls, to simplify future changes.
15780 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15782 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15784 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15785 Use much-faster test for byte-length change.
15786 Don't assume string byte-length fits in 'int'.
15787 Check that character arg fits in 'int'.
15788 (mapcar1): Declare byte as byte, for clarity.
15790 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15792 * fns.c (concat): Catch string overflow earlier.
15793 Do not rely on integer wraparound.
15795 * dispextern.h (struct it.overlay_strings_charpos)
15796 (struct it.selective): Now EMACS_INT, not int.
15797 * xdisp.c (forward_to_next_line_start)
15798 (back_to_previous_visible_line_start)
15799 (reseat_at_next_visible_line_start, next_element_from_buffer):
15800 Don't arbitrarily truncate the value of 'selective' to int.
15802 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15804 * composite.c: Don't truncate sizes to 'int'.
15805 (composition_gstring_p, composition_reseat_it)
15806 (composition_adjust_point): Use EMACS_INT, not int.
15807 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15808 not EMACS_UINT, for indexes.
15810 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15812 * buffer.c: Include <verify.h>.
15813 (struct sortvec.priority, struct sortstr.priority):
15814 Now EMACS_INT, not int.
15815 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15816 (struct sortstr.size, record_overlay_string)
15817 (struct sortstrlist.size, struct sortlist.used):
15818 Don't truncate size to int.
15819 (record_overlay_string): Check for size-calculation overflow.
15820 (init_buffer_once): Check at compile-time, not run-time.
15822 2011-06-22 Jim Meyering <meyering@redhat.com>
15824 Don't leak an XBM-image-sized buffer
15825 * image.c (xbm_load): Free the image buffer after using it.
15827 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15830 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15831 that Sun C diagnosed.
15832 * fns.c (secure_hash): Fix pointer signedness issue.
15833 * intervals.c (static_offset_intervals): New function.
15834 (offset_intervals): Use it.
15836 2011-06-21 Leo Liu <sdl.web@gmail.com>
15839 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15842 * fns.c (secure_hash): Rename from crypto_hash_function and change
15843 the first arg to accept symbols.
15844 (Fsecure_hash): New primitive.
15845 (syms_of_fns): New symbols.
15847 2011-06-20 Deniz Dogan <deniz@dogan.se>
15849 * process.c (Fset_process_buffer): Clarify return value in
15852 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15854 * dispnew.c (add_window_display_history): Use BVAR.
15856 * xdisp.c (debug_method_add): Use BVAR.
15857 (check_window_end, dump_glyph_matrix, dump_glyph)
15858 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15860 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15863 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15864 check till after the cache is created in init_frame_faces.
15866 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15868 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15870 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15872 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15873 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15874 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15876 Improve buffer-overflow checking (Bug#8873).
15877 * fileio.c (Finsert_file_contents):
15878 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15879 Remove the old (too-loose) buffer overflow checks.
15880 They weren't needed, since make_gap checks for buffer overflow.
15881 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15882 The old code merely checked for Emacs fixnum overflow, and relied
15883 on undefined (wraparound) behavior. The new code avoids undefined
15884 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15886 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15887 Tune. Don't use wider integers than needed. Don't use alloca.
15888 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15890 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15892 * insdel.c, lisp.h (buffer_overflow): New function.
15893 (insert_from_buffer_1, replace_range, replace_range_2):
15894 * insdel.c (make_gap_larger):
15895 * editfns.c (Finsert_char):
15896 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15898 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15900 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15902 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15904 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15905 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15907 * fileio.c: Don't assume EMACS_INT fits in off_t.
15908 (emacs_lseek): New static function.
15909 (Finsert_file_contents, Fwrite_region): Use it.
15910 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15912 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15914 * fns.c: Don't overflow int when computing a list length.
15915 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15916 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15917 truncation on 64-bit hosts. Check for QUIT every
15918 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15919 faster and is responsive enough.
15920 (Flength): Report an error instead of overflowing an integer.
15921 (Fsafe_length): Return a float if the value is not representable
15922 as a fixnum. This shouldn't happen except in contrived situations.
15923 (Fnthcdr, Fsort): Don't assume list length fits in int.
15924 (Fcopy_sequence): Don't assume vector length fits in int.
15926 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15927 (header_size, word_size): New constants.
15928 (allocate_vectorlike): Don't check size overflow here.
15929 (allocate_vector): Check it here instead, since this is the only
15930 caller of allocate_vectorlike that could cause overflow.
15931 Check that the new vector's length is representable as a fixnum.
15933 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15934 The previous code was bogus. For example, next_almost_prime (32)
15935 returned 39, which is undesirable as it is a multiple of 3; and
15936 next_almost_prime (24) returned 25, which is a multiple of 5 so
15937 why was the code bothering to check for multiples of 7?
15939 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15941 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15943 Variadic C functions now count arguments with ptrdiff_t.
15944 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15945 Back then I didn't know that the Emacs coding style prefers signed int.
15946 Also, in the meantime I found a few more instances where arguments
15947 were being counted with int, which may truncate counts on 64-bit
15948 machines, or EMACS_INT, which may be unnecessarily wide.
15949 * lisp.h (struct Lisp_Subr.function.aMANY)
15950 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15951 Arg counts are now ptrdiff_t, not size_t.
15952 All variadic functions and their callers changed accordingly.
15953 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15954 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15955 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15956 * callint.c (Fcall_interactively): Check arg count for overflow,
15957 to avoid potential buffer overrun. Use signed char, not 'int',
15958 for 'varies' array, so that we needn't bother to check its size
15959 calculation for overflow.
15960 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15961 * eval.c (apply_lambda):
15962 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15963 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15964 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15966 * callint.c (Fcall_interactively): Don't use index var as event count.
15968 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15969 * mem-limits.h (SIZE): Remove; no longer used.
15971 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15973 Remove unnecessary casts.
15974 * xterm.c (x_term_init):
15975 * xfns.c (x_set_border_pixel):
15976 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15977 These aren't needed now that we assume ANSI C.
15979 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15980 It's more likely to cause problems (due to unsigned overflow)
15983 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15985 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15987 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15989 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15991 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15993 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15995 GLYPH_CODE_FACE returns EMACS_INT, not int.
15996 * dispextern.h (merge_faces):
15997 * xfaces.c (merge_faces):
15998 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15999 Don't assume EMACS_INT fits in int.
16001 * character.h (CHAR_VALID_P): Remove unused parameter.
16002 * fontset.c, lisp.h, xdisp.c: All uses changed.
16004 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16006 * fns.c (concat): Minor tuning based on overflow analysis.
16007 This doesn't fix any bugs. Use int to hold character, instead
16008 of constantly refetching from Emacs object. Use XFASTINT, not
16009 XINT, for value known to be a character. Don't bother comparing
16010 a single byte to 0400, as it's always less.
16012 * floatfns.c (Fexpt):
16013 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16015 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16018 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16020 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16021 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16022 incorrectly succeed when S was a string, because 4294967386 was
16023 truncated before it was used.
16025 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16026 Otherwise, an out-of-range integer could cause undefined behavior
16029 * composite.c: Use int, not EMACS_INT, for characters.
16030 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16031 EMACS_INT, for values that are known to be in character range.
16032 This doesn't fix any bugs but is the usual style inside Emacs and
16033 may generate better code on 32-bit machines.
16035 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16036 This is for reasons similar to the recent CHAR_STRING fix.
16037 * charset.c (Fencode_char): Check that character arg is actually
16038 a character. Pass an int to ENCODE_CHAR.
16039 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16040 wider than 'int', as a compile-time check to prevent future regressions
16043 * character.c (char_string): Remove unnecessary casts.
16045 Make sure a 64-bit char is never passed to CHAR_STRING.
16046 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16047 by silently ignoring the top 32 bits, allowing some values
16048 that were far too large to be valid characters.
16049 * character.h: Include <verify.h>.
16050 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16051 arguments are no wider than unsigned, as a compile-time check
16052 to prevent future regressions in this area.
16054 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16055 (Fsubst_char_in_region):
16057 * xdisp.c (decode_mode_spec_coding):
16058 Adjust to CHAR_STRING's new requirement.
16059 * editfns.c (Finsert_char, Fsubst_char_in_region):
16060 * fns.c (concat): Check that character args are actually
16061 characters. Without this test, these functions did the wrong
16062 thing with wildly out-of-range values on 64-bit hosts.
16064 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16065 These casts should not be needed on 32-bit hosts, either.
16066 * keyboard.c (read_char):
16067 * lread.c (Fload): Remove casts to unsigned.
16069 * lisp.h (UNSIGNED_CMP): New macro.
16070 This fixes comparison bugs on 64-bit hosts.
16071 (ASCII_CHAR_P): Use it.
16072 * casefiddle.c (casify_object):
16073 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16074 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16075 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16076 * dispextern.h (FACE_FROM_ID):
16077 * keyboard.c (read_char): Use UNSIGNED_CMP.
16079 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16080 not to EMACS_INT, to avoid GCC warning.
16082 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16084 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16085 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16086 isn't needed on 32-bit machines.
16088 * buffer.c (Fgenerate_new_buffer_name):
16089 Use EMACS_INT for count, not int.
16090 (advance_to_char_boundary): Return EMACS_INT, not int.

16099 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16100 * alloc.c (make_save_value): Integer argument is now of type
16101 ptrdiff_t, not int.
16102 (mark_object): Use ptrdiff_t, not int.
16103 * lisp.h (pD): New macro.
16104 * print.c (print_object): Use it.

16108 (total_free_conses, total_free_markers, total_free_symbols)
16109 (total_free_floats, total_floats, total_free_intervals)
16110 (total_intervals, total_strings, total_free_strings):
16111 Now EMACS_INT, not int. All uses changed.
16112 (Fgarbage_collect): Compute overall total using a double, so that
16113 integer overflow is less likely to be a problem. Check for overflow
16114 when converting back to an integer.
16115 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16116 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16117 These were 'int' variables that could overflow on 64-bit hosts;
16118 they were never used, so remove them instead of repairing them.
16119 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16120 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16121 Previously, this ceilinged at INT_MAX, but that doesn't work on
16123 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16125 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16126 (allocate_vectorlike): Check for ptrdiff_t overflow.
16127 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16128 when a (possibly-narrower) signed value would do just as well.
16129 We prefer using signed arithmetic, to avoid comparison confusion.
16131 * alloc.c: Catch some string size overflows that we were missing.
16132 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16133 for convenience in STRING_BYTES_MAX.
16134 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16135 The definition here is exact; the one in lisp.h was approximate.
16136 (allocate_string_data): Check for string overflow. This catches
16137 some instances we weren't catching before. Also, it catches
16138 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16139 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16140 and ptrdiff_t and EMACS_INT are both 64 bits.
16142 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16143 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16144 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16146 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16148 * alloc.c (Fmake_string): Check for out-of-range init.

16713 (bidi_paragraph_init, bidi_resolve_explicit_1)
16714 (bidi_level_of_next_char): Call bidi_fetch_char and

16721 instead of using explicit *_CHAR codes.
16722 (bidi_resolve_explicit, bidi_resolve_weak):

16731 (bidi_level_of_next_char): Don't try to lookup the cache for the
16732 next/previous character if nothing is cached there yet, or if we
16733 were just reseat()'ed to a new position.
16735 * xdisp.c (set_cursor_from_row): Set start and stop points
16736 according to the row's direction when priming the loop that looks
16737 for the glyph on which to display cursor.
16738 (single_display_spec_intangible_p): Function deleted.
16739 (display_prop_intangible_p): Reimplement to call
16740 handle_display_spec instead of single_display_spec_intangible_p.
16741 Accept 3 additional arguments needed by handle_display_spec.
16742 This fixes incorrect cursor motion across display property with complex
16743 values: lists, `(when COND...)' forms, etc.

16745 lists with the argument STRING its top-level element.
16746 (display_prop_string_p): Fix the condition for processing a
16747 property that is a list to be consistent with handle_display_spec.

16749 last portion of handle_display_prop.
16750 (compute_display_string_pos): Accept additional argument
16751 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
16752 value of a `display' property is a "replacing spec".
16753 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16754 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
16755 the display property, but just return a value indicating whether
16756 the display property will replace the characters it covers.
16757 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
16758 frame_window_p members of struct bidi_it.
16759 (compute_display_string_pos, compute_display_string_end):

16765 * keyboard.c (adjust_point_for_property): Adjust the call to
16766 display_prop_intangible_p to its new signature.

16782 All callers changed. (Bug#8762)
16784 * gnutls.c: Use Emacs's memory allocators.
16785 Without this change, the gnutls library would invoke malloc etc.
16786 directly, which causes problems on non-SYNC_INPUT hosts, and which
16787 runs afoul of improving memory_full behavior. (Bug#8761)
16788 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16789 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16790 xfree instead of the default malloc, realloc, free.
16791 (Fgnutls_boot): No need to check for memory allocation failure,
16792 since xmalloc does that for us.
16794 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

16814 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
16815 for hashes and hash indexes, instead of 'unsigned' and 'int'.
16816 * alloc.c (allocate_vectorlike):
16817 Check for overflow in vector size calculations.
16818 * ccl.c (ccl_driver):
16819 Check for overflow when converting EMACS_INT to int.

16821 need to be updated by these changes.
16822 * fns.c (make_hash_table, maybe_resize_hash_table):
16823 Check for integer overflow with large hash tables.
16824 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16825 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16826 (SXHASH_REDUCE): New macro.
16827 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16828 Use it instead of discarding useful hash info with large hash values.
16829 (sxhash_float): New function.
16830 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16831 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16832 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16833 Rewrite to use FIXNUM_BITS, as this simplifies things.
16834 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16835 Adjust signatures to match updated version of code.
16836 (consing_since_gc): Now EMACS_INT, since a single hash table can
16837 use more than INT_MAX bytes.

16886 Make it possible to run ./temacs.
16888 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16889 syms_of_callproc does the same thing. Remove test for
16890 "initialized", do it in the caller.
16891 * emacs.c (main): Avoid calling set_initial_environment when dumping.

16934 (x_clipboard_manager_save_all): New functions.
16935 (Fx_clipboard_manager_save): Lisp function deleted.
16937 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16938 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16940 * xterm.h: Update prototype.
16942 2011-05-28 William Xu <william.xwl@gmail.com>
16944 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16945 exiting (Bug#8239).
16947 2011-05-28 Jim Meyering <meyering@redhat.com>
16949 Avoid a sign-extension bug in crypto_hash_function.
16950 * fns.c (to_uchar): Define.
16951 (crypto_hash_function): Use it to convert some newly-signed
16952 variables to unsigned, to avoid sign-extension bugs. For example,
16953 without this change, (md5 "truc") would evaluate to
16954 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16955 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16956 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16958 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16960 Integer overflow fixes.
16962 * dbusbind.c: Serial number integer overflow fixes.
16963 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16964 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16965 to hold a serial number that is too large for a fixnum.
16966 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16967 Check for serial numbers out of range. Decode any serial number
16968 that was so large that it became a float. (Bug#8722)
16970 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16971 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16972 Use XFASTINT rather than XUINT when numbers are nonnegative.
16973 (xd_append_arg, Fdbus_method_return_internal):
16974 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16975 arguments, check that Lisp number is nonnegative, rather than
16976 silently wrapping negative numbers around. (Bug#8722)
16977 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16980 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16982 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16984 ccl: Add integer overflow checks.
16985 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16986 (IN_INT_RANGE): New macros.
16987 (ccl_driver): Use them to check for integer overflow when
16988 decoding a CCL program. Many of the new checks are whether XINT (x)
16989 fits in int; it doesn't always, on 64-bit hosts. The new version
16990 doesn't catch all possible integer overflows, but it's an
16991 improvement. (Bug#8719)
16993 * alloc.c (make_event_array): Use XINT, not XUINT.
16994 There's no need for unsigned here.
16996 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16997 This follows up to the 2011-05-06 change that substituted uintptr_t
16998 for EMACS_INT. This case wasn't caught back then.
17000 Rework Fformat to avoid integer overflow issues.
17001 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17002 now (part of C89). Include <verify.h>.
17003 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17004 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17005 (Fformat): Avoid the prepass trying to compute sizes; it was only
17006 approximate and thus did not catch overflow reliably. Instead, walk
17007 through the format just once, formatting and computing sizes as we go,
17008 checking for integer overflow at every step, and allocating a larger
17009 buffer as needed. Keep track separately whether the format is
17010 multibyte. Keep only the most-recently calculated precision, rather
17011 than them all. Record whether each argument has been converted to
17012 string. Use EMACS_INT, not int, for byte and char and arg counts.
17013 Support field widths and precisions larger than INT_MAX. Avoid
17014 sprintf's undefined behavior with conversion specifications such as %#d
17015 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17016 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17017 formatting out-of-range floating point numbers with int
17018 formats. (Bug#8668)
17020 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17022 * data.c: Avoid integer truncation in expressions involving floats.
17023 * data.c: Include <intprops.h>.
17024 (arith_driver): When there's an integer overflow in an expression
17025 involving floating point, convert the integers to floating point
17026 so that the resulting value does not suffer from catastrophic
17027 integer truncation. For example, on a 64-bit host (* 4
17028 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17029 Do not rely on undefined behavior after integer overflow.
17031 merge count_size_as_multibyte, parse_str_to_multibyte
17032 * character.c, character.h (count_size_as_multibyte):
17033 Rename from parse_str_to_multibyte; all uses changed.
17034 Check for integer overflow.
17035 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17036 since it's now a duplicate of the other. This is more of
17037 a character than a buffer op, so better that it's in character.c.
17038 * fns.c, print.c: Adjust to above changes.
17040 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17042 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17044 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17046 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17047 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17048 (x_clipboard_manager_save): Now static.
17049 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17051 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17052 (crypto_hash_function): Now static.
17053 Fix pointer signedness problems. Avoid unnecessary initializations.
17055 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17057 * termhooks.h (Vselection_alist): Make it terminal-local.
17059 * terminal.c (create_terminal): Initialize it.
17061 * xselect.c: Support for clipboard managers.
17062 (Vselection_alist): Move to termhooks.h as terminal-local var.
17063 (LOCAL_SELECTION): New macro.
17064 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17065 (symbol_to_x_atom): Remove gratuitous arg.
17066 (x_handle_selection_request, lisp_data_to_selection_data)
17067 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17068 (x_own_selection, x_get_local_selection, x_convert_selection):
17069 New arg, specifying work frame. Use terminal-local Vselection_alist.
17070 (some_frame_on_display): Delete unused function.
17071 (Fx_own_selection_internal, Fx_get_selection_internal)
17072 (Fx_disown_selection_internal, Fx_selection_owner_p)
17073 (Fx_selection_exists_p): New optional frame arg.
17074 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17075 (x_handle_selection_clear): Don't treat other terminals with the
17076 same keyboard specially. Use the terminal-local Vselection_alist.
17077 (x_clear_frame_selections): Use Frun_hook_with_args.
17079 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17081 * xterm.h: Add support for those atoms.
17083 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17085 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17086 (converted_selections, conversion_fail_tag): New global variables.
17087 (x_selection_request_lisp_error): Free the above.
17088 (x_get_local_selection): Remove unnecessary code.
17089 (x_reply_selection_request): Args changed; handle arbitrary array
17090 of converted selections stored in converted_selections.
17091 Separate the XChangeProperty and SelectionNotify steps.
17092 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17093 (x_convert_selection): New function.
17094 (x_handle_selection_event): Simplify.
17095 (x_get_foreign_selection): Don't ignore incoming requests while
17096 waiting for an answer; this will fail when we implement
17097 SAVE_TARGETS, and seems unnecessary anyway.
17098 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17099 (Vx_sent_selection_functions): Doc fix.
17101 2011-05-26 Leo Liu <sdl.web@gmail.com>
17103 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17105 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17107 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17109 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17110 for fringe update if it has periodic bitmap.
17111 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17112 and fringe_bitmap_periodic_p.
17114 * fringe.c (get_fringe_bitmap_data): New function.
17115 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17116 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17117 row. Mark glyph row for fringe update if periodicity changed.
17119 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17120 for fringe update unless it has periodic bitmap.
17122 2011-05-25 Kenichi Handa <handa@m17n.org>
17124 * xdisp.c (get_next_display_element): Set correct it->face_id for
17125 a static composition.
17127 2011-05-24 Leo Liu <sdl.web@gmail.com>
17130 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17132 * fns.c (crypto_hash_function, Fsha1): New function.
17133 (Fmd5): Use crypto_hash_function.
17134 (syms_of_fns): Add Ssha1.
17136 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17138 * gnutls.c: Remove unused macros.
17139 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17140 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17141 Remove macros that are defined and never used.
17142 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17144 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17146 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17147 (Fx_get_selection_internal): Minor cleanup.
17148 (Fx_own_selection_internal): Rename arguments for consistency with
17151 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17153 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17155 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17157 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17159 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17161 * dispnew.c (scrolling_window): Don't exclude the case that the
17162 last enabled row in the desired matrix touches the bottom boundary.
17164 2011-05-21 Glenn Morris <rgm@gnu.org>
17166 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17167 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17168 and add some more files.
17170 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17172 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17173 report_file_error introduced by the change from 2011-05-07.
17175 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17177 * systime.h (Time): Define only if emacs is defined.
17178 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17179 where the include path doesn't have X11/X.h by default. See
17180 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17182 2011-05-20 Kenichi Handa <handa@m17n.org>
17184 * composite.c (find_automatic_composition): Fix previous change.
17186 2011-05-20 Glenn Morris <rgm@gnu.org>
17188 * lisp.mk: New file, split from Makefile.in.
17189 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17190 (shortlisp): Remove.
17191 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17193 2011-05-19 Glenn Morris <rgm@gnu.org>
17195 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17196 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17197 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17198 (lisp): Set the order to that of loadup.el.
17199 (shortlisp): Make it a copy of $lisp.
17200 (SOME_MACHINE_LISP): Remove.
17201 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17202 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17204 2011-05-18 Kenichi Handa <handa@m17n.org>
17206 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17207 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17208 (find_automatic_composition): Mostly rewrite for efficiency.
17210 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17212 * makefile.w32-in: Update dependencies.
17214 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17216 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17217 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17219 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17221 Fix some integer overflow issues, such as string length overflow.
17223 * insdel.c (count_size_as_multibyte): Check for string overflow.
17225 * character.c (lisp_string_width): Check for string overflow.
17226 Use EMACS_INT, not int, for string indexes and lengths; in
17227 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17228 the resulting string length overflows an EMACS_INT; instead,
17229 report a string overflow if no precision given. When checking for
17230 precision exhaustion, use a check that cannot possibly have
17231 integer overflow. (Bug#8675)
17232 * character.h (lisp_string_width): Adjust to new signature.
17234 * alloc.c (string_overflow): New function.
17235 (Fmake_string): Use it. This doesn't change behavior, but saves
17236 a few bytes and will simplify future changes.
17237 * character.c (string_escape_byte8): Likewise.
17238 * lisp.h (string_overflow): New decl.
17240 Fixups, following up to the user-interface timestamp change.
17241 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17242 for UI timestamps, instead of unsigned long.
17243 * msdos.c (mouse_get_pos): Likewise.
17244 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17245 * w32gui.h (Time): Define by including "systime.h" rather than by
17246 declaring it ourselves. (Bug#8664)
17248 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17249 * image.c (clear_image_cache): Likewise.
17251 * term.c (term_mouse_position): Don't assume time_t wraparound.
17253 Be more systematic about user-interface timestamps.
17254 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17255 and sometimes 'EMACS_UINT', to represent these timestamps.
17256 This change causes it to use 'Time' uniformly, as that's what X uses.
17257 This makes the code easier to follow, and makes it easier to catch
17258 integer overflow bugs such as Bug#8664.
17259 * frame.c (Fmouse_position, Fmouse_pixel_position):
17260 Use Time, not unsigned long, for user-interface timestamps.
17261 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17262 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17263 * keyboard.h (last_event_timestamp): Likewise.
17264 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17265 * menu.h (xmenu_show): Likewise.
17266 * term.c (term_mouse_position): Likewise.
17267 * termhooks.h (struct input_event.timestamp): Likewise.
17268 (struct terminal.mouse_position_hook): Likewise.
17269 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17270 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17271 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17272 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17273 what it was before.
17274 * menu.h, termhooks.h: Include "systime.h", for Time.
17276 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17277 Don't assume that the difference between two unsigned long values
17278 can fit into an integer. At this point, we know button_down_time
17279 <= event->timestamp, so the difference must be nonnegative, so
17280 there's no need to cast the result if double-click-time is
17281 nonnegative, as it should be; check that it's nonnegative, just in
17282 case. This bug is triggered when events are more than 2**31 ms
17283 apart (about 25 days). (Bug#8664)
17285 * xselect.c (last_event_timestamp): Remove duplicate decl.
17286 (x_own_selection): Remove needless cast to unsigned long.
17288 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17289 that always fit in int. Use a sentinel instead of a counter, to
17290 avoid a temp and to allay GCC's concerns about possible int overflow.
17291 * frame.h (struct frame): Use int for menu_bar_items_used
17292 instead of EMACS_INT, since it always fits in int.
17294 * menu.c (grow_menu_items): Check for int overflow.
17296 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17298 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17299 Before, the code was not consistent. These values cannot exceed
17300 2**31 - 1 so there's no need to make them unsigned.
17301 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17302 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17303 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17305 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17307 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17308 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17309 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17310 presumably because the widths might not match.
17312 * window.c (size_window): Avoid needless test at loop start.
17314 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17316 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17318 2011-05-12 Drew Adams <drew.adams@oracle.com>
17320 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17322 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17324 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17325 `width' to `bar_area_x' and `bar_area_width', respectively.
17326 (x_scroll_run): Take account of fringe background extension.
17328 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17329 Rename local vars `left' and `width' to `bar_area_x' and
17330 `bar_area_width', respectively.
17331 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17332 background extension.
17334 2011-05-10 Jim Meyering <meyering@redhat.com>
17336 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17338 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17340 * image.c (Finit_image_library): Return t for built-in image types,
17341 like pbm and xbm. (Bug#8640)
17343 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17345 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17347 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17349 * w32console.c (Fset_screen_color): Doc fix.
17350 (Fget_screen_color): New function.
17351 (syms_of_ntterm): Defsubr it.
17353 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17354 unlink the temporary file if Fcall_process didn't create it in the
17356 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17357 child process will be redirected to a file specified with `:file'.
17358 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17359 cue to call_process_cleanup not to close that handle.
17361 2011-05-07 Ben Key <bkey76@gmail.com>
17363 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17364 one of two shell specific rules, either bootstrap-temacs-CMD or
17365 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17366 to the previous implementation of the bootstrap-temacs rule.
17367 The bootstrap-temacs-CMD rule is similar to the previous
17368 implementation of the bootstrap-temacs rule except that it
17369 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17372 These changes, along with some changes to nt/configure.bat,
17373 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17374 earlier fix to add support for --cflags and --ldflags options
17375 that include quotes so that it works whether make uses cmd or
17378 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17380 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17381 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17383 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17384 a string. Handle both cases.
17385 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17386 (Fdbus_register_method): Use Qinvalid_function.
17388 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17390 * makefile.w32-in: Update dependencies.
17391 (LISP_H): Add inttypes.h and stdin.h.
17392 (PROCESS_H): Add unistd.h.
17394 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17396 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17397 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17399 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17401 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17403 * term.c (vfatal): Remove stray call to va_end.
17404 It's not needed and the C Standard doesn't allow it here anyway.
17406 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17407 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17409 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17412 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17414 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17416 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17418 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17420 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17422 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17423 * charset.c (Fdefine_charset_internal): Don't initialize
17424 charset.code_space[15]. The value was garbage, on hosts with
17425 32-bit int (Bug#8600).
17427 * lread.c (read_integer): Be more consistent with string-to-number.
17428 Use string_to_number to do the actual conversion; this avoids
17429 rounding errors and fixes some other screwups. Without this fix,
17430 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17431 (digit_to_number): Move earlier, for benefit of read_integer.
17432 Return -1 if the digit is out of range for the base, -2 if it is
17433 not a digit in any supported base. (Bug#8602)
17435 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17437 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17438 to match comment at start of function. This also removes a
17439 GCC warning about overflow in a 32+64-bit port.
17441 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17443 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17444 Reported by Stefan Monnier in
17445 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17446 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17447 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17449 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17450 (EMACS_UINTPTR): Likewise, with uintptr_t.
17452 * lisp.h: Prefer 64-bit EMACS_INT if available.
17453 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17454 on 32-bit hosts that have 64-bit int, so that they can access
17456 However, temporarily disable this change unless the temporary
17457 symbol WIDE_EMACS_INT is defined.
17459 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17461 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17462 This removes an assumption that EMACS_INT and long are the same
17463 width as pointers. The assumption is true for Emacs porting targets
17464 now, but we want to make other targets possible.
17465 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17466 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17467 In the rest of the code, change types of integers that hold casted
17468 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17469 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17470 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17471 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17472 No need to cast type when ORing.
17473 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17474 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17475 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17476 assume EMACS_INT is the same width as char *.
17477 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17478 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17479 Remove no-longer-needed casts.
17480 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17481 (xg_tool_bar_help_callback, xg_make_tool_item):
17482 Use EMACS_INTPTR to hold an integer
17483 that will be cast to void *; this can avoid a GCC warning
17484 if EMACS_INT is not the same width as void *.
17485 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17486 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17487 (current_message_1, set_message_1):
17488 Use a local to convert to proper width without a cast.
17489 * xmenu.c (dialog_selection_callback): Likewise.
17491 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17492 Also, don't assume VALBITS / RAND_BITS is less than 5,
17493 and don't rely on undefined behavior when shifting a 1 left into
17495 * lisp.h (get_random): Change signature to match.
17497 * lread.c (hash_string): Use size_t, not int, for hash computation.
17498 Normally we prefer signed values; but hashing is special, because
17499 it's better to use unsigned division on hash table sizes so that
17500 the remainder is nonnegative. Also, size_t is the natural width
17501 for hashing into memory. The previous code used 'int', which doesn't
17502 retain enough info to hash well into very large tables.
17503 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17505 * dbusbind.c: Don't possibly lose pointer info when converting.
17506 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17507 Use XPNTR rather than XHASH, so that the high-order bits of
17508 the pointer aren't lost when converting through void *.
17510 * eval.c (Fautoload): Don't double-shift a pointer.
17512 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17514 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17516 * gnutls.c (DEF_GNUTLS_FN):
17517 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17519 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17521 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17524 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17526 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17527 New version that can reserve upto 2GB of heap space.
17529 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17531 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17533 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17535 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17536 `gnutls_certificate_set_x509_key_file'.
17538 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17540 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17541 Update dependencies.
17543 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17545 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17546 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17547 Remove unused parameter `fildes'.
17548 * process.c (read_process_output, send_process): Don't pass it.
17550 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17552 Fix previous change: the library cache is defined in w32.c.
17553 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17554 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17556 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17558 Implement dynamic loading of GnuTLS on Windows.
17560 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17561 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17562 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17565 * gnutls.c (Qgnutls_dll): Define.
17566 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17567 (gnutls_*): Declare function pointers.
17568 (init_gnutls_functions): New function to initialize function pointers.

17570 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
17571 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17572 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17573 (emacs_gnutls_write, emacs_gnutls_read)
17574 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17575 (Fgnutls_available_p): New function.
17576 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
17577 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
17578 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.

17586 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17588 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17589 (w32_delayed_load): Move from image.c. When loading a library, record
17590 its filename in the :loaded-from property of the library id.
17591 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17592 Initialize and staticpro them.
17593 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17595 * process.c: Include lisp.h before w32.h, not after.
17596 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17597 instead of gnutls_record_check_pending.
17599 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17601 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17603 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17604 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17607 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17609 * xterm.c (x_set_frame_alpha): Do not set property on anything
17610 else than FRAME_X_OUTER_WINDOW (Bug#8608).
17612 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17614 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
17616 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17618 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

17628 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
17630 * callproc.c: Indentation fixup.
17632 * sysdep.c (wait_for_termination_1): Make static.
17633 (wait_for_termination, interruptible_wait_for_termination):
17634 Move after wait_for_termination_1.
17636 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
17638 * sysdep.c (interruptible_wait_for_termination): New function
17639 which is like wait_for_termination, but allows keyboard
17642 * callproc.c (Fcall_process): Add (:file "file") as an option for
17644 (Fcall_process_region): Ditto.
17646 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17648 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17649 rather than `XVECTOR (FOO)->size'.
17651 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17652 inttypes.h, as a gnulib replacement is used if it not available in
17655 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17657 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17658 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17659 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17661 * coding.c (coding_alloc_by_realloc): Error out if destination
17662 will grow beyond MOST_POSITIVE_FIXNUM.
17663 (decode_coding_emacs_mule): Abort if there isn't enough place in
17664 charbuf for the composition carryover bytes. Reserve an extra
17665 space for up to 2 characters produced in a loop.
17666 (decode_coding_iso_2022): Abort if there isn't enough place in
17667 charbuf for the composition carryover bytes.
17669 2011-04-21 Eli Zaretskii <eliz@gnu.org>

17672 aborting when %lld or %lll format is passed.
17673 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
17674 %llo or %llx format is passed. (Bug#8545)
17676 * window.c (window_scroll_line_based): Use a marker instead of
17677 simple variables to record original value of point. (Bug#7952)
17679 * doprnt.c (doprnt): Fix the case where a multibyte sequence
17680 produced by %s or %c overflows available buffer space. (Bug#8545)
17682 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17684 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

17713 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
17715 * makefile.w32-in: Update dependencies.
17717 2011-04-27 Eli Zaretskii <eliz@gnu.org>
17719 Improve `doprnt' and its usage. (Bug#8545)
17720 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17721 `format_end'. Remove support for %l as a conversion specifier.
17722 Don't use xrealloc. Improve diagnostics when the %l size modifier
17723 is used. Update the commentary.
17725 * eval.c (verror): Simplify calculation of size_t.
17727 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17730 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17732 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17735 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17737 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17738 This makes this file independent of the recent pseudovector change.
17740 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17742 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17744 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17745 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17746 Remove unused local.
17747 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17749 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17750 GCC 4.6.0 optimizes based on type-based alias analysis.
17751 For example, if b is of type struct buffer * and v of type struct
17752 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17753 != &v->size, and therefore "v->size = 1; b->size = 2; return
17754 v->size;" must therefore return 1. This assumption is incorrect
17755 for Emacs, since it type-puns struct Lisp_Vector * with many other
17756 types. To fix this problem, this patch adds a new type struct
17757 vectorlike_header that documents the constraints on layout of vectors
17758 and pseudovectors, and helps optimizing compilers not get fooled
17759 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17760 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17761 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17763 (XSETPVECTYPE): Rewrite in terms of new macro.
17764 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17765 This is a bit clearer, and further avoids the possibility of
17766 undesirable aliasing.
17767 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17768 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17769 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17770 since Lisp_Subr is a special case (no "next" field).
17771 (ASIZE): Now uses header.size rather than size.
17772 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17773 to avoid the hassle of writing XVECTOR (foo)->header.size.
17774 (struct vectorlike_header): New type.
17775 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17776 object, to help avoid aliasing.
17777 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17778 (SUBRP): Likewise, since Lisp_Subr is a special case.
17779 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17780 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17781 (struct Lisp_Hash_Table): Combine first two members into a single
17782 struct vectorlike_header member. All uses of "size" and "next" members
17783 changed to be "header.size" and "header.next".
17784 * buffer.h (struct buffer): Likewise.
17785 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17786 * frame.h (struct frame): Likewise.
17787 * process.h (struct Lisp_Process): Likewise.
17788 * termhooks.h (struct terminal): Likewise.
17789 * window.c (struct save_window_data, struct saved_window): Likewise.
17790 * window.h (struct window): Likewise.
17791 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17792 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17793 * buffer.c (init_buffer_once): Likewise.
17794 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17796 * process.c (Fformat_network_address): Use local var for size,
17799 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17801 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17802 * data.c (atof): Remove decl; no longer used or needed.
17803 (digit_to_number): Move to lread.c.
17804 (Fstring_to_number): Use new string_to_number function, to be
17805 consistent with how the Lisp reader treats infinities and NaNs.
17806 Do not assume that floating-point numbers represent EMACS_INT
17807 without losing information; this is not true on most 64-bit hosts.
17808 Avoid double-rounding errors, by insisting on integers when
17809 parsing non-base-10 numbers, as the documentation specifies.
17810 * lisp.h (string_to_number): New decl, replacing ...
17811 (isfloat_string): Remove.
17812 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17813 (read1): Do not accept +. and -. as integers; this
17814 appears to have been a coding error. Similarly, do not accept
17815 strings like +-1e0 as floating point numbers. Do not report
17816 overflow for integer overflows unless the base is not 10 which
17817 means we have no simple and reliable way to continue.
17818 Break out the floating-point parsing into a new
17819 function string_to_number, so that Fstring_to_number parses
17820 floating point numbers consistently with the Lisp reader.
17821 (digit_to_number): Move here from data.c. Make it static inline.
17822 (E_CHAR, EXP_INT): Remove, replacing with ...
17823 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17824 (string_to_number): New function, replacing isfloat_string.
17825 This function checks for valid syntax and produces the resulting
17826 Lisp float number too. Rework it so that string-to-number
17827 no longer mishandles examples like "1.0e+". Use strtoumax,
17828 so that overflow for non-base-10 numbers is reported only when
17829 there's no portable and simple way to convert to floating point.
17831 * textprop.c (set_text_properties_1): Rewrite for clarity,
17832 and to avoid GCC warning about integer overflow.
17834 * intervals.h (struct interval): Use EMACS_INT for members
17835 where EMACS_UINT might cause problems. See
17836 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17837 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17838 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17840 (offset_intervals): Tell GCC not to worry about length overflow
17841 when negating a negative length.
17843 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17844 (overrun_check_free): Likewise.
17846 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17847 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17850 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17851 (gnutls_make_error): Rename local to avoid shadowing.
17852 (gnutls_emacs_global_deinit): ifdef out; not used.
17853 (Fgnutls_boot): Use const for pointer to readonly storage.
17854 Comment out unused local. Fix pointer signedness problems.
17856 * lread.c (openp): Don't stuff size_t into an 'int'.
17857 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17858 about possible signed overflow.
17860 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17861 (GDK_KEY_g): Don't define if already defined.
17862 (xg_prepare_tooltip): Avoid pointer signedness problem.
17863 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17865 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17866 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17868 * xfns.c (Fx_window_property): Simplify a bit,
17869 to make a bit faster and to avoid GCC 4.6.0 warning.
17870 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17872 * fns.c (internal_equal): Don't assume size_t fits in int.
17874 * alloc.c (compact_small_strings): Tighten assertion a little.
17876 Replace pEd with more-general pI, and fix some printf arg casts.
17877 * lisp.h (pI): New macro, generalizing old pEd macro to other
17878 conversion specifiers. For example, use "...%"pI"d..." rather
17879 than "...%"pEd"...".
17880 (pEd): Remove. All uses replaced with similar uses of pI.
17881 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17882 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17883 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17884 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17885 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17886 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17887 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17889 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17890 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17891 * print.c (safe_debug_print, print_object): Likewise.
17892 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17894 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17895 avoiding the 0 flag, which is not portable.
17896 * process.c (Fmake_network_process): Use pI to avoid cast.
17897 * region-cache.c (pp_cache): Likewise.
17898 * xdisp.c (decode_mode_spec): Likewise.
17899 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17900 behavior on 64-bit hosts with printf arg.
17901 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17902 (x_stop_queuing_selection_requests): Likewise.
17903 (x_get_window_property): Don't truncate byte count to an 'int'
17906 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17907 here, since it parses constructs like leading '-' and spaces,
17908 which are not wanted; and it overflows with large numbers.
17909 Instead, simply match F[0-9]+, which is what is wanted anyway.
17911 * alloc.c: Remove unportable assumptions about struct layout.
17912 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17913 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17914 (allocate_vectorlike, make_pure_vector): Use the new macros,
17915 plus offsetof, to remove unportable assumptions about struct layout.
17916 These assumptions hold on all porting targets that I know of, but
17917 they are not guaranteed, they're easy to remove, and removing them
17918 makes further changes easier.
17920 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17921 This doesn't fix a bug but makes the code clearer.
17922 (string_overrun_cookie): Now const. Use initializers that
17923 don't formally overflow signed char, to avoid warnings.
17924 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17925 can cause Emacs to crash when string overrun checking is enabled.
17926 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17927 multiple of sizeof (EMACS_INT); it need not be, if
17928 alignof(EMACS_INT) < sizeof (EMACS_INT).
17929 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17931 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17938 supposed to be handshaking. (Bug#8556)
17939 Reported by Paul Eggert <eggert@cs.ucla.edu>.
17941 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
17943 * lisp.h (Qdebug): List symbol.
17944 * eval.c (Qdebug): Restore global linkage.

17952 (check_string_free_list): Convert to standard C.
17954 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
17956 * w32.c (emacs_gnutls_push): Fix typo.
17958 2011-04-25 Eli Zaretskii <eliz@gnu.org>
17960 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17961 "cast to pointer from integer of different size".
17963 Improve doprnt and its use in verror. (Bug#8545)
17964 * doprnt.c (doprnt): Document the set of format control sequences
17965 supported by the function. Use SAFE_ALLOCA instead of always
17968 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17969 is one byte too soon. Don't use xrealloc; instead xfree and
17972 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17974 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
17977 * gnutls.c: Renamed global_initialized to
17978 gnutls_global_initialized. Added internals for the
17979 :verify-hostname-error, :verify-error, and :verify-flags
17980 parameters of `gnutls-boot' and documented those parameters in the
17981 docstring. Start callback support.
17982 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17983 unless a fatal error occurred. Call gnutls_alert_send_appropriate
17984 on error. Return error code.

18044 changes in globals.h immediately force recompilation.
18045 (TAGS): Depend on $(CURDIR)/m/intel386.h and
18046 $(CURDIR)/s/ms-w32.h.

18056 * doprnt.c: Include limits.h.
18057 (SIZE_MAX): New macro.
18058 (doprnt): Return a size_t value. 2nd arg is now size_t.
18059 Many local variables are now size_t instead of int or unsigned.
18060 Improve overflow protection. Support `l' modifier for integer
18061 conversions. Support %l conversion. Don't assume an EMACS_INT
18062 argument for integer conversions and for %c.
18064 * lisp.h (doprnt): Restore prototype.
18066 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18067 $(SRC)/character.h.
18069 * Makefile.in (base_obj): Add back doprnt.o.
18071 * deps.mk (doprnt.o): Add back prerequisites.
18072 (callint.o): Depend on character.h.
18074 * eval.c (internal_lisp_condition_case): Include the handler
18075 representation in the error message.
18076 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
18077 when breaking from the loop.

18081 * callint.c (Fcall_interactively): When displaying error message
18082 about invalid control letter, pass the character's codepoint, not
18083 a pointer to its multibyte form. Improve display of the character
18084 in octal and display also its hex code.
18086 * character.c (char_string): Use %x to display the (unsigned)
18087 codepoint of an invalid character, to avoid displaying a bogus
18090 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18091 `error', not SYMBOL_NAME itself.
18093 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18094 character arguments to `error'.
18096 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18097 to `error' in error message about FINAL_CHAR argument. Make sure
18098 FINAL_CHAR is a character, and use %c when it is passed as
18099 argument to `error'.

18163 Define only if needed.
18165 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18166 by pacifying GCC about it. Maybe it's time to retire it?
18167 * xfaces.c (USG, __TIMEVAL__): Likewise.
18169 * dispextern.h (struct redisplay_interface): Rename param
18170 to avoid shadowing.
18171 * termhooks.h (struct terminal): Likewise.
18172 * xterm.c (xembed_send_message): Likewise.
18174 * insdel.c (make_gap_smaller): Define only if
18175 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
18177 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
18180 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
18181 so that we aren't warned about unused symbols.
18183 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
18185 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

18194 define if USE_GTK || USE_X_TOOLKIT.
18195 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
18196 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

18198 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
18200 * xmenu.c (menu_help_callback): Pointer type fixes.
18201 Use const pointers when pointing at readonly data. Avoid pointer

18217 * bitmaps: Change bitmaps from unsigned char back to the X11
18218 compatible char. Avoid the old compiler warnings about
18219 out-of-range initializers by using, for example, '\xab' rather
18222 * xgselect.c (xgselect_initialize): Check vs interface
18223 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

18288 * nsfont.m: Fixed bugs in ns_get_family and
18289 ns_descriptor_to_entity that were caused by using free to
18290 deallocate memory blocks that were allocated by xmalloc (via
18291 xstrdup). This caused Emacs to crash when compiled with
18292 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18293 --enable-checking=xmallocoverrun). xfree is now used to
18294 deallocate these memory blocks.

18312 * process.c (send_process): Adjust to the new signatures of
18313 emacs_write and emacs_gnutls_write. Do not attempt to store

18684 to see whether these variables are used from other modules.
18685 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
18686 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
18687 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
18688 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:

18690 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
18691 * xmenu.c, xselect.c:
18692 Declare Q* vars static if they are not used in other modules.

18694 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
18695 Remove decls of unexported vars.
18696 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
18698 * lisp.h (DEFINE_FUNC): Make sname 'static'.
18700 Make Emacs functions such as Fatom 'static' by default.
18701 This makes it easier for human readers (and static analyzers)
18702 to see whether these functions can be called from other modules.
18703 DEFUN now defines a static function. To make the function external
18704 so that it can be used in other C modules, use the new macro DEFUE.
18705 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
18706 (Finit_image_library):
18707 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
18708 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
18709 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18710 Remove decls, since these functions are now static.
18711 (Funintern, Fget_internal_run_time): New decls, since these functions
18712 were already external.
18714 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
18715 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

18718 * keyboard.c, keymap.c, lread.c:
18719 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
18720 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
18721 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
18722 Mark functions with DEFUE instead of DEFUN,
18723 if they are used in other modules.
18724 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18725 decls for now-static functions.
18726 * buffer.h (Fdelete_overlay): Remove decl.
18727 * callproc.c (Fgetenv_internal): Mark as internal.
18728 * composite.c (Fremove_list_of_text_properties): Remove decl.

18732 * doc.c (Fdocumntation_property): New forward static decl.
18733 * eval.c (Ffetch_bytecode): New forward static decl.
18734 (Funintern): Remove extern decl; now in .h file where it belongs.
18735 * fileio.c (Fmake_symbolic_link): New forward static decl.
18736 * image.c (Finit_image_library): New forward static decl.
18737 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
18738 * intervals.h (Fprevious_property_change):
18739 (Fremove_list_of_text_properties): Remove decls.
18740 * keyboard.c (Fthis_command_keys): Remove decl.
18741 (Fcommand_execute): New forward static decl.
18742 * keymap.c (Flookup_key): New forward static decl.
18743 (Fcopy_keymap): Now static.
18744 * keymap.h (Flookup_key): Remove decl.
18745 * process.c (Fget_process): New forward static decl.
18746 (Fprocess_datagram_address): Mark as internal.

18757 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
18759 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
18762 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18764 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18765 when at ZV. (Bug#8487)
18767 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18769 * charset.c (Fclear_charset_maps): Use xfree instead of free.
18771 * keyboard.c (parse_tool_bar_item): Likewise.
18772 * sound.c (sound_cleanup, alsa_close): Likewise.
18773 * termcap.c (tgetent): Likewise.
18774 * xfns.c (x_default_font_parameter): Likewise.
18775 * xsettings.c (read_and_apply_settings): Likewise.
18777 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18778 (overrun_check_free): Protoize.
18780 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18782 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18783 since callers should never pass a negative size.
18784 Change the signature to match that of plain 'read' and 'write'; see
18785 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18786 * lisp.h: Update prototypes of emacs_write and emacs_read.
18788 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18790 * xdisp.c (redisplay_window): Don't try to determine the character
18791 position of the scroll margin if the window start point w->startp
18792 is outside the buffer's accessible region. (Bug#8468)
18794 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18796 Fix write-region and its subroutines for buffers > 2GB.
18797 * fileio.c (a_write, e_write): Modify declaration of arguments and
18798 local variables to support buffers larger than 2GB.
18799 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18801 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18802 argument, local variables, and return value.
18804 * lisp.h: Update prototypes of emacs_write and emacs_read.
18806 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18808 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18810 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18812 Fix more problems found by GCC 4.6.0's static checks.
18814 * xdisp.c (vmessage): Use a better test for character truncation.
18816 * charset.c (load_charset_map): <, not <=, for optimization,
18817 and to avoid potential problems with integer overflow.
18818 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18819 * casetab.c (set_identity, shuffle): Likewise.
18820 * editfns.c (Fformat): Likewise.
18821 * syntax.c (skip_chars): Likewise.
18823 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18824 This also lets GCC 4.6.0 generate slightly better loop code.
18826 * callint.c (Fcall_interactively): <, not <=, for optimization.
18827 (Fcall_interactively): Count the number of arguments produced,
18828 not the number of arguments given. This is simpler and lets GCC
18829 4.6.0 generate slightly better code.
18831 * ftfont.c: Distingish more carefully between FcChar8 and char.
18832 The previous code passed unsigned char * to a functions like
18833 strlen and xstrcasecmp that expect char *, which does not
18834 conform to the C standard.
18835 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18836 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18837 char * when the C standard requires it.
18839 * keyboard.c (read_char): Remove unused var.
18841 * eval.c: Port to Windows vsnprintf (Bug#8435).
18842 Include <limits.h>.
18843 (SIZE_MAX): Define if the headers do not.
18844 (verror): Do not give up if vsnprintf returns a negative count.
18845 Instead, grow the buffer. This ports to Windows vsnprintf, which
18846 does not conform to C99. Problem reported by Eli Zaretskii.
18847 Also, simplify the allocation scheme, by avoiding the need for
18848 calling realloc, and removing the ALLOCATED variable.
18850 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18852 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18853 But keep the doprint source code for now, as we might revamp it
18854 and use it again (Bug#8435).
18855 * lisp.h (doprnt): Remove.
18856 * Makefile.in (base_obj): Remove doprnt.o.
18857 * deps.mk (doprnt.o): Remove.
18859 error: Print 32- and 64-bit integers portably (Bug#8435).
18860 Without this change, on typical 64-bit hosts error ("...%d...", N)
18861 was used to print both 32- and 64-bit integers N, which relied on
18862 undefined behavior.
18863 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18864 * lisp.h (error, verror): Mark as printf-like functions.
18865 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18866 Report overflow in size calculations when allocating printf buffer.
18867 Do not truncate output string at its first null byte.
18868 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18869 Truncate the output at a character boundary, since vsnprintf does not
18871 * charset.c (check_iso_charset_parameter): Convert internal
18872 character to string before calling 'error', since %c now has the
18874 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18875 overflow when computing char to be passed to 'error'. Do not
18876 pass Lisp_Object to 'error'; pass the integer instead.
18877 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18878 formatted with plain %d.
18880 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18882 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18884 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18886 * xterm.c (x_catch_errors): Remove duplicate declaration.
18888 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18890 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18892 2011-04-10 Jim Meyering <meyering@redhat.com>
18894 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18895 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18896 return ssize_t not "int", and use size_t as the buffer length.
18897 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18898 * gnutls.h: Update declarations.
18899 * process.c (read_process_output): Use ssize_t, to match.
18900 (send_process): Likewise.
18902 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18904 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18906 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18908 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18909 Use unsigned char, to match FcChar8 type definition.
18911 * xterm.c (handle_one_xevent):
18912 * xmenu.c (create_and_show_popup_menu):
18913 * xselect.c (x_decline_selection_request)
18914 (x_reply_selection_request): Avoid type-punned deref of X events.
18916 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18918 Fix some uses of `int' instead of EMACS_INT.
18919 * search.c (string_match_1, fast_string_match)
18920 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18921 (scan_buffer, find_next_newline_no_quit)
18922 (find_before_next_newline, search_command, Freplace_match)
18923 (Fmatch_data): Make some `int' variables be EMACS_INT.
18925 * xdisp.c (display_count_lines): 3rd argument and return value now
18926 EMACS_INT. All callers changed.
18927 (pint2hrstr): Last argument is now EMACS_INT.
18929 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18930 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18931 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18932 (decode_coding_utf_16, decode_coding_emacs_mule)
18933 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
18934 (decode_coding_ccl, decode_coding_charset)
18935 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18936 (decode_coding_iso_2022, decode_coding_emacs_mule)
18937 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18938 <char_offset, last_offset>: Declare EMACS_INT.
18939 (encode_coding_utf_8, encode_coding_utf_16)
18940 (encode_coding_emacs_mule, encode_invocation_designation)
18941 (encode_designation_at_bol, encode_coding_iso_2022)
18942 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18943 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18945 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18946 (encode_invocation_designation): Last argument P_NCHARS is now
18948 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18949 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18951 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18954 * ccl.c (Fccl_execute_on_string): Declare some variables
18957 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18959 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18961 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18963 * process.c (Fformat_network_address): Doc fix.
18965 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18967 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18969 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18971 * keyboard.c (read_char): Call Lisp function help-form-show,
18972 instead of using internal_with_output_to_temp_buffer.
18973 (Qhelp_form_show): New var.
18974 (syms_of_keyboard): Use DEFSYM macro.
18976 * print.c (internal_with_output_to_temp_buffer): Function deleted.

18980 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18982 * process.c (Flist_processes): Remove to Lisp.
18983 (list_processes_1): Delete.
18985 2011-04-06 Eli Zaretskii <eliz@gnu.org>
18987 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18989 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18991 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18993 Fix more problems found by GCC 4.6.0's static checks.
18995 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18997 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18999 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19001 * xdisp.c (vmessage): Mark as a printf-like function.
19003 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19005 * sound.c (sound_warning): Don't crash if arg contains a printf format.

19010 to system-supplied API.
19012 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19014 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19015 This avoids several warnings with gcc -Wstrict-overflow.
19016 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19017 directly, rather than having caller test rule sign. This avoids
19018 some unnecessary tests.
19019 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19020 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19021 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19023 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19024 (xfont_open): Avoid unnecessary tests.
19026 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19028 * composite.h, composite.c (composition_gstring_put_cache):
19029 Use EMACS_INT, not int, for length.

19032 breaking out part of COMPOSITION_DECODE_RULE.
19033 (COMPOSITION_DECODE_RULE): Use it.

19035 by using the new macro.
19037 * textprop.c (set_text_properties_1): Change while to do-while,
19038 since the condition is always true at first.
19040 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19041 (interval_deletion_adjustment): Return unsigned value.
19044 * process.c (list_processes_1, create_pty, read_process_output):
19045 (exec_sentinel): Remove vars that were set but not used.
19046 (create_pty): Remove unnecessary "volatile"s.

19056 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19057 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19058 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19060 * print.c (print_error_message): Avoid int overflow.
19062 * font.c (font_list_entities): Redo for clarity,
19063 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19065 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19066 (font_score): Avoid potential overflow in diff calculation.
19068 * fns.c (substring_both): Remove var that is set but not used.
19069 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19071 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19073 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19074 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19075 can always succeed if overflow has undefined behavior.
19077 * search.c (boyer_moore, wordify): Remove vars set but not used.
19078 (wordify): Omit three unnecessary tests.
19080 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19081 All callers changed. This avoids the need for an unused var.
19083 * casefiddle.c (casify_region): Remove var that is set but not used.
19085 * dired.c (file_name_completion): Remove var that is set but not used.
19087 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19089 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19090 (Finsert_file_contents): Remove unnecessary code checking fd.
19092 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19093 Check for integer overflow on size calculations.
19095 * buffer.c (Fprevious_overlay_change): Remove var that is set
19098 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19099 Remove vars that are set but not used.
19100 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19101 (timer_check_2): Mark vars as initialized.
19103 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19105 * image.c (lookup_image): Remove var that is set but not used.
19106 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19108 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19109 that are set but not used.
19111 * xfns.c (make_invisible_cursor): Don't return garbage
19112 if XCreateBitmapFromData fails (Bug#8410).
19114 * xselect.c (x_get_local_selection, x_handle_property_notify):
19115 Remove vars that are set but not used.
19117 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19118 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19120 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19121 Remove var that is set but not used.
19122 (scroll_bar_windows_size): Now size_t, not int.
19123 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19124 Check for overflow.
19126 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19127 (map_tty_color) [!defined MSDOS]: Likewise.
19129 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19131 * coding.c: Remove vars that are set but not used.
19132 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

19139 that is set but not used.
19141 * print.c (print_object): Remove var that is set but not used.
19143 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19144 The gnulib version avoids calling malloc in the usual case,
19145 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19146 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19147 * filelock.c (current_lock_owner): Likewise.
19148 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19149 * sysdep.c: Include allocator.h, careadlinkat.h.
19150 (emacs_no_realloc_allocator): New static constant.
19151 (emacs_readlink): New function.
19152 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19153 ../lib/careadlinkat.h.
19155 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19157 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

19179 do not dereference NULL upon failed strdup
19180 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19181 (ns_get_family): Likewise.
19183 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19185 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19187 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19189 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19192 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19194 Add lexical binding.
19196 * window.c (Ftemp_output_buffer_show): New fun.

19205 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19207 (syms_of_lread): Declare `lexical-binding'.
19209 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19211 * keyboard.c (eval_dyn): New fun.
19212 (menu_item_eval_property): Use it.
19214 * image.c (parse_image_spec): Use Ffunctionp.
19216 * fns.c (concat, mapcar1): Accept byte-code-functions.
19218 * eval.c (Fsetq): Handle lexical vars.
19219 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19220 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19221 (FletX, Flet): Obey lexical binding.
19222 (Fcommandp): Handle closures.
19223 (Feval): New `lexical' arg.
19224 (eval_sub): New function extracted from Feval. Use it almost
19225 everywhere where Feval was used. Look up vars in lexical env.
19227 (Ffunctionp): Move from subr.el.
19228 (Ffuncall): Handle closures.
19229 (apply_lambda): Remove `eval_flags'.
19230 (funcall_lambda): Handle closures and new byte-code-functions.
19231 (Fspecial_variable_p): New function.
19232 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19233 but without exporting it to Lisp.
19235 * doc.c (Fdocumentation, store_function_docstring):
19236 * data.c (Finteractive_form): Handle closures.
19238 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19241 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19243 (exec_byte_code): New function extracted from Fbyte_code to handle new
19244 calling convention for byte-code-functions. Add new byte-codes.
19246 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19248 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19250 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19252 * xdisp.c (redisplay_internal): Fix prototype.
19254 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19256 * xdisp.c (SCROLL_LIMIT): New macro.
19257 (try_scrolling): Use it when setting scroll_limit.
19258 Limit scrolling to 100 screen lines.
19259 (redisplay_window): Even when falling back on "recentering",
19260 position point in the window according to scroll-conservatively,
19261 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19263 (try_scrolling): When point is above the window, allow searching
19264 as far as scroll_max, or one screenful, to compute vertical
19265 distance from PT to the scroll margin position. This prevents
19266 try_scrolling from unnecessarily failing when
19267 scroll-conservatively is set to a value slightly larger than the
19268 window height. Clean up the case of PT below the margin at bottom
19269 of window: scroll_max can no longer be INT_MAX. When aggressive
19270 scrolling is in use, don't let point enter the opposite scroll
19271 margin as result of the scroll.
19272 (syms_of_xdisp) <scroll-conservatively>: Document the
19273 threshold of 100 lines for never-recentering scrolling.
19275 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

19280 (message_log_check_duplicate): Remove parameters `prev_bol' and
19281 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19282 (redisplay_internal): Remove parameter `preserve_echo_area',
19283 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19285 * indent.c (Fvertical_motion):
19286 * window.c (window_scroll_pixel_based, Frecenter):
19287 Don't pass `need_y_p' to `move_it_by_lines'.
19289 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19291 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19292 steal a few bits to be more compact.
19293 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19294 Remove unneeded casts.
19296 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19298 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19300 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19301 binding" message (bug#7967).
19303 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19305 Fix more problems found by GCC 4.6.0's static checks.
19307 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19308 Remove unused local var.
19310 * editfns.c (Fmessage_box): Remove unused local var.
19312 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19313 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19314 Omit unused local vars.
19315 * window.c (shrink_windows): Omit unused local var.
19316 * menu.c (digest_single_submenu): Omit unused local var.
19317 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19318 Omit unused local var.
19320 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19321 Don't assume string length fits in int.
19322 (keyremap_step, read_key_sequence): Use size_t for sizes.

19326 instead of alloca (Bug#8344).
19328 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19329 (Fbacktrace_frame): Don't assume nframes fits in int.
19331 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

19338 * cm.c (calccost): Turn while-do into do-while, for clarity.
19340 * keyboard.c (syms_of_keyboard): Use the same style as later
19341 in this function when indexing through an array. This also
19342 works around GCC bug 48267.
19344 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19346 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19348 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19349 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19351 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19352 This avoids undefined behavior on integer overflow, and is a bit
19353 more convenient anyway since it is compared to a size_t variable.
19355 Variadic C functions now count arguments with size_t, not int.
19356 This avoids an unnecessary limitation on 64-bit machines, which
19357 caused (substring ...) to crash on large vectors (Bug#8344).

19367 * fns.c (concat): Likewise.
19368 * frame.c (x_set_frame_parameters): Likewise.
19369 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19370 0 if not found, not -1. All callers changed.
19372 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19373 (stack_copy_size): Now size_t, not int.
19374 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

19395 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19396 don't set the hook to nil, but remove the offending function instead.
19397 (Qcommand_hook_internal): Remove, unused.
19398 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19399 Vcommand_hook_internal.

19402 (funcall_nil, funcall_not): New functions.
19403 (run_hook_with_args): Call each function through a `funcall' argument.

19567 2011-03-23 Julien Danjou <julien@danjou.info>
19569 * term.c (Fsuspend_tty, Fresume_tty):
19570 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
19571 * window.c (temp_output_buffer_show):
19572 * insdel.c (signal_before_change):
19573 * frame.c (Fhandle_switch_frame):
19574 * fileio.c (Fdo_auto_save):
19575 * emacs.c (Fkill_emacs):
19576 * editfns.c (save_excursion_restore):
19577 * cmds.c (internal_self_insert):
19578 * callint.c (Fcall_interactively):
19579 * buffer.c (Fkill_all_local_variables):
19580 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19582 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19583 unconditionally since it does the check itself.
19585 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19587 Fix more problems found by GCC 4.5.2's static checks.
19589 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19590 the first time through the loop, since we know p0 < p1 then.
19591 This also avoids a gcc -Wstrict-overflow warning.
19593 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19594 leading to a memory leak, possible in functions like
19595 load_charset_map_from_file that can allocate an unbounded number
19596 of objects (Bug#8318).
19598 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19599 that could (at least in theory) be that large.
19601 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19602 This is less likely to overflow, and avoids undefined behavior if
19603 overflow does occur. All callers changed. Use strtoul to scan
19604 for the unsigned long integer.
19605 (pint2hrstr): Simplify and tune code slightly.
19606 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
19608 * scroll.c (do_scrolling): Work around GCC bug 48228.
19609 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
19611 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
19612 This also avoids a warning with gcc -Wstrict-overflow.
19613 (validate_x_resource_name): Simplify count usage.
19614 This also avoids a warning with gcc -Wstrict-overflow.
19616 * fileio.c (Fcopy_file): Report error if fchown or fchmod
19619 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
19621 * process.c (Fmake_network_process): Use socklen_t, not int,
19622 where POSIX says socklen_t is required in portable programs.
19623 This fixes a porting bug on hosts like 64-bit HP-UX, where
19624 socklen_t is wider than int (Bug#8277).
19625 (Fmake_network_process, server_accept_connection):
19626 (wait_reading_process_output, read_process_output):
19629 * process.c: Rename or move locals to avoid shadowing.

19639 Make tparam.h and terminfo.c consistent.
19640 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19641 Include tparam.h instead, since it declares them.
19642 * cm.h (PC): Remove extern decl; tparam.h now does this.
19643 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19644 * terminfo.c: Include tparam.h, to check interfaces.
19645 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19646 (tparam): Adjust signature to match interface in tparam.h;
19647 this removes some undefined behavior. Check that outstring and len
19648 are zero, which they always are with Emacs.
19649 * tparam.h (PC, BC, UP): New extern decls.
19651 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19652 (xftfont_open): Rename locals to avoid shadowing.
19654 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
19655 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
19656 (OTF_TAG_SYM): Omit macro if not needed.

19664 * xml.c (make_dom): Now static.
19666 * composite.c (composition_compute_stop_pos): Rename local to
19668 (composition_reseat_it): Remove unused locals.
19669 (find_automatic_composition, composition_adjust_point): Likewise.
19670 (composition_update_it): Mark var as initialized.
19671 (find_automatic_composition): Mark vars as initialized,
19672 with a FIXME (Bug#8290).
19674 character.h: Rename locals to avoid shadowing.
19675 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
19676 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
19677 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
19678 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19679 to avoid shadowing.
19681 * textprop.c (property_change_between_p): Remove; unused.
19683 * intervals.c (interval_start_pos): Now static.
19685 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

19688 Rename locals to avoid shadowing.
19690 * sound.c (wav_play, au_play, Fplay_sound_internal):
19691 Fix pointer signedness.
19692 (alsa_choose_format): Remove unused local var.
19693 (wav_play): Initialize a variable to 0, to prevent undefined
19694 behavior (Bug#8278).
19696 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
19698 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
19700 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
19701 clobbering (Bug#8298).
19702 * sysdep.c (sys_subshell): Likewise.
19703 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19705 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19706 This should get cleaned up, so that child_setup has the
19707 same signature on all platforms.
19709 * callproc.c (call_process_cleanup): Now static.
19710 (relocate_fd): Rename locals to avoid shadowing.
19712 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19714 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19715 not to be necessary, and produces flickering.
19717 2011-03-20 Glenn Morris <rgm@gnu.org>
19719 * config.in: Remove file.
19721 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
19723 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
19724 are now in src/globals.h.
19725 (syms_of_minibuf): Remove spurious & from previous change.
19727 2011-03-20 Leo Liu <sdl.web@gmail.com>
19729 * minibuf.c (completing-read-function): New variable.
19730 (completing-read-default): Rename from completing-read.
19731 (completing-read): Call completing-read-function.
19733 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
19735 * xfaces.c (Fx_load_color_file):
19736 Read color file from absolute filename (bug#8250).
19738 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
19740 * makefile.w32-in: Update dependencies.
19742 2011-03-17 Eli Zaretskii <eliz@gnu.org>
19744 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

19751 (sigchld_handler): Now static.
19753 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
19754 That way, the code declares only the vars that it needs.
19755 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
19756 * s/cygwin.h (PTY_ITERATION): Likewise.
19757 * s/darwin.h (PTY_ITERATION): Likewise.

19764 (CONSTANTLIM): Remove; unused.
19765 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
19766 Define only if needed.
19768 * unexelf.c (unexec): Name an expression,
19769 to avoid gcc -Wbad-function-cast warning.
19770 Use a different way to cause a compilation error if anyone uses
19771 n rather than nn, a way that does not involve shadowing.
19772 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
19774 * deps.mk (unexalpha.o): Remove; unused.
19776 New file unexec.h, the (simple) interface for unexec (Bug#8267).
19777 * unexec.h: New file.
19778 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
19779 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
19780 Depend on unexec.h.
19781 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
19782 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
19783 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
19784 Change as necessary to match prototype in unexec.h.
19786 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

19802 instead of using an uninitialized var.
19803 (font_sort_entities): Mark var as initialized.
19805 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
19807 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

19831 * callint.c (quotify_arg, quotify_args): Now static.
19832 (Fcall_interactively): Rename locals to avoid shadowing.
19833 Use const pointer when appropriate.

19839 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
19840 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
19841 some of which prompt warnings from gcc -Wbad-function-cast.
19842 (Fformat_time_string, Fencode_time, Finsert_char):
19843 (Ftranslate_region_internal, Fformat):
19844 Rename or remove local vars to avoid shadowing.
19845 (Ftranslate_region_internal): Mark var as initialized.
19847 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
19850 * lisp.h (eassert): Check that the argument compiles, even if
19851 ENABLE_CHECKING is not defined.
19853 * data.c (Findirect_variable): Name an expression, to avoid
19854 gcc -Wbad-function-cast warning.
19855 (default_value, arithcompare, arith_driver, arith_error): Now static.

19862 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
19863 Rename locals to avoid shadowing.
19864 (mark_stack): Move local variables into the #ifdef region where
19866 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
19867 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
19869 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
19870 (GC_STRING_CHARS): Remove; not used.
19871 (Fmemory_limit): Cast sbrk's returned value to char *.
19873 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
19874 avoids undefined behavior in theory.
19876 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
19878 Use functions, not macros, for up- and down-casing (Bug#8254).
19879 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19880 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
19881 to use the following functions instead of these macros.
19882 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19883 EMACS_INT, since callers assume the returned value fits in int.
19884 (upcase1): Likewise, for UPCASE_TABLE.
19885 (uppercasep, lowercasep, upcase): New static inline functions.
19886 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
19887 the race-condition problem in the old DOWNCASE.
19889 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
19890 Rename locals to avoid shadowing.
19891 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
19892 (regex_compile, re_search_2, re_match_2_internal):
19893 Remove unused local vars.
19894 (FREE_VAR): Rewrite so as not to use empty "else",
19895 which gcc can warn about.
19896 (regex_compile, re_match_2_internal): Mark locals as initialized.
19897 (RETALLOC_IF): Define only if needed.
19898 (WORDCHAR_P): Likewise. This one is never needed, but is used
19899 only in a comment talking about a compiler bug, so put inside
19900 the #if 0 of that comment.
19901 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19902 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
19905 * search.c (boyer_moore): Rename locals to avoid shadowing.
19906 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
19907 (PREV_CHAR_BOUNDARY): Likewise.

19917 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
19919 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
19920 Rename locals to avoid shadowing.
19921 (Fvertical_motion): Mark locals as initialized.
19923 * casefiddle.c (casify_object, casify_region): Now static.
19924 (casify_region): Mark local as initialized.
19926 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
19928 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
19929 New macros, so that the caller can use some names other than
19930 gcpro1, gcpro2, etc.
19931 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19933 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19934 argument, for consistency with GCPRO2_VAR, etc: it is now the
19935 prefix of the variable, not the variable itself. All uses
19937 * dired.c (directory_files_internal, file_name_completion):
19938 Rename locals to avoid shadowing.
19940 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19941 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19942 dired.c's scmp function, had undefined behavior.
19943 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19944 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19945 * buffer.h: ... to here, because these macros use current_buffer,
19946 and the new implementation with inline functions needs to have
19947 current_buffer in scope now, rather than later when the macros
19949 (downcase, upcase1): New static inline functions.
19950 (DOWNCASE, UPCASE1): Reimplement using these functions.
19951 This avoids undefined behavior in expressions like
19952 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19953 from race conditions in accessing the global variables
19954 case_temp1 and case_temp2.
19955 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19956 * lisp.h (case_temp1, case_temp2): Remove their decls.
19957 * character.h (ASCII_CHAR_P): Move from here ...
19958 * lisp.h: ... to here, so that the inline functions mentioned
19959 above can use them.
19961 * dired.c (directory_files_internal_unwind): Now static.
19963 * fileio.c (file_name_as_directory, directory_file_name):
19964 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
19966 (file_name_as_directory): Use const pointers when appropriate.
19967 (Fexpand_file_name): Likewise. In particular, newdir might
19968 point at constant storage, so make it a const pointer.
19969 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
19970 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19972 (Fset_file_times, Finsert_file_contents, auto_save_error):
19973 Rename locals to avoid shadowing.
19975 * minibuf.c (choose_minibuf_frame_1): Now static.
19976 (Ftry_completion, Fall_completions): Rename or remove locals
19977 to avoid shadowing.
19979 * marker.c (bytepos_to_charpos): Remove; unused.
19981 * lisp.h (verify_bytepos, count_markers): New decls,
19982 so that gcc does not warn that these functions aren't declared.
19984 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
19985 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19986 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19987 (copy_text): Remove unused local var.
19989 * filelock.c (within_one_second): Now static.
19990 (lock_file_1): Rename local to avoid shadowing.
19992 * buffer.c (fix_overlays_before): Mark locals as initialized.
19993 (fix_start_end_in_overlays): Likewise. This function should be
19994 simplified by using pointers-to-pointers, but that's a different
19996 (switch_to_buffer_1): Now static.
19997 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19998 (report_overlay_modification): Rename locals to avoid shadowing.
20000 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
20001 Fix pointer signedness issue.
20002 (sys_subshell): Mark local as volatile if checking for lint,
20003 to suppress a gcc -Wclobbered warning that does not seem to be right.
20004 (MAXPATHLEN): Define only if needed.
20006 * process.c (serial_open, serial_configure): Move decls from here ...
20007 * systty.h: ... to here, so that they can be checked.
