37 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
38 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
39 for some of that bug's symptoms can now cause Emacs to abort.
40 Remove the workaround.
41 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
42 The bug that caused SIGCHLD to get lost has been fixed, and the

73 * w32proc.c (new_child): Initialize input_file and
74 pending_deletion members of the child.
75 (delete_child): Delete the child's temporary input file, if any,
76 that is pending deletion.

89 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
90 asynchronous subprocess, record the name of the input file name,
92 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
93 delete the file, record it as pending deletion when the subprocess
96 2012-12-14 Eli Zaretskii <eliz@gnu.org>

123 * dired.c (Ffile_attributes) [WINDOWSNT]:
124 Set w32_stat_get_owner_group to a non-zero value, to request accurate
125 owner and group information from 'lstat'.
127 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
129 * fileio.c (Finsert_file_contents): Don't put tail into head area,
130 as that confuses set-auto-coding, so insist on the head-read
131 returning the full 1024 bytes. Let lseek compute the tail offset;
132 less work for us. Do not ignore I/O errors when reading the tail.

159 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
161 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
162 fstat shouldn't fail, and if it does fail copy-file should not proceed.
163 Remove unnecessary S_ISLNK test, as (contra the comments) this
164 function can't copy symlinks. Improve quality of error message
165 when attempting to copy files that are neither regular files nor

190 it->start_of_box_run_p.
191 (append_space_for_newline): If the glyph row is R2L, reset the
192 iterator's end_of_box_run_p flag before prepending the space glyph.
193 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
194 iterator's start_of_box_run_p flag before prepending the stretch.

502 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
504 Fix a recently-introduced delete-process race condition.
505 * callproc.c, process.h (record_kill_process):
506 New function, containing part of the old call_process_kill.
507 (call_process_kill): Use it.
508 This does not change call_process_kill's behavior.
509 * process.c (Fdelete_process): Use record_kill_process to fix a
510 race condition that could cause Emacs to lose track of a child.
512 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
514 Avoid code duplication between prev_frame and next_frame.
515 * frame.c (candidate_frame): New function. Add comment.
516 (prev_frame, next_frame): Use it. Adjust comment.
518 2012-12-06 Eli Zaretskii <eliz@gnu.org>
520 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
521 fails, signal an error instead of continuing with an empty
523 Encode expanded temp file pattern before passing it to mkstemp or
526 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
527 Encode the file name before passing it to dostounix_filename, in
528 case it will downcase it (under w32-downcase-file-names).
531 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
533 Minor call-process cleanups.
534 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
535 at the same time as other platforms, to simplify analysis.
536 No need for fd0_volatile since we have synch_process_fd.
537 Avoid needless emacs_close; arg is always negative.
539 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
541 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
544 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
546 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
547 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
548 and mouse_face_hidden members to a bitfields.
549 * frame.h (struct frame): Remove set-but-not-used space_width member.
550 (FRAME_SPACE_WIDTH): Remove.
551 * nsterm.m, w32term.c, xterm.c: Adjust users.
552 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
553 member. Adjust users. Convert term_initted, delete_in_insert_mode,
554 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
555 members to a bitfields.
557 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
559 Don't let call-process be a zombie factory (Bug#12980).
560 Fixing this bug required some cleanup of the signal-handling code.
561 As a side effect, this change also fixes a longstanding rare race
562 condition whereby Emacs could mistakenly kill unrelated processes,
563 and it fixes a bug where a second C-g does not kill a recalcitrant
564 synchronous process in GNU/Linux and similar platforms.
565 The patch should also fix the last vestiges of Bug#9488,
566 a bug which has mostly been fixed on the trunk by other changes.
567 * callproc.c, process.h (synch_process_alive, synch_process_death)
568 (synch_process_termsig, sync_process_retcode):
569 Remove. All uses removed, to simplify analysis and so that
570 less consing is done inside critical sections.
571 * callproc.c (call_process_exited): Remove. All uses replaced
572 with !synch_process_pid.
573 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
574 These take the role of what used to be in unwind-protect arg.
576 (block_child_signal, unblock_child_signal):
577 New functions, to avoid races that could kill innocent-victim processes.
578 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
579 (call_process_kill): Record killed processes as deleted, so that
580 zombies do not clutter up the system. Do this inside a critical
581 section, to avoid a race that would allow the clutter.
582 (call_process_cleanup): Fix code so that the second C-g works again
583 on common platforms such as GNU/Linux.
584 (Fcall_process): Create the child process in a critical section,
585 to fix a race condition. If creating an asynchronous process,
586 record it as deleted so that zombies do not clutter up the system.
587 Do unwind-protect for WINDOWSNT too, as that's simpler in the
588 light of these changes. Omit unnecessary call to emacs_close
589 before failure, as the unwind-protect code does that.
590 * callproc.c (call_process_cleanup):
591 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
592 * process.c (record_deleted_pid): New function, containing
593 code refactored out of Fdelete_process.
594 (Fdelete_process): Use it.
595 (process_status_retrieved): Remove. All callers changed to use
597 (record_child_status_change): Remove, folding its contents into ...
598 (handle_child_signal): ... this signal handler. Now, this
599 function is purely a handler for SIGCHLD, and is not called after
600 a synchronous waitpid returns; the synchronous code is moved to
601 wait_for_termination. There is no need to worry about reaping
602 more than one child now.
603 * sysdep.c (get_child_status, child_status_changed): New functions.
604 (wait_for_termination): Now takes int * status and bool
605 interruptible arguments, too. Do not record child status change;
606 that's now the caller's responsibility. All callers changed.
607 Reimplement in terms of get_child_status.
608 (wait_for_termination_1, interruptible_wait_for_termination):
609 Remove. All callers changed to use wait_for_termination.
610 * syswait.h: Include <stdbool.h>, for bool.
611 (record_child_status_change, interruptible_wait_for_termination):
613 (record_deleted_pid, child_status_changed): New decls.
614 (wait_for_termination): Adjust to API changes noted above.
616 * bytecode.c, lisp.h (Qbytecode): Remove.
617 No longer needed after 2012-11-20 interactive-p changes.
619 2012-12-03 Eli Zaretskii <eliz@gnu.org>
621 * xdisp.c (redisplay_window): If the cursor is visible, but inside
622 the scroll margin, move point outside the margin. (Bug#13055)
624 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
626 * gtkutil.c (my_log_handler): New function.

631 * lisp.h (modify_region): Rename to...
632 (modify_region_1): ...new prototype.

634 * insdel.c (modify_region): Rename to...
635 (modify_region_1): ...new function to work with current buffer.
636 Adjust comment and users. Use true and false for booleans.
638 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
640 * alloc.c (free_save_value): New function.
641 (safe_alloca_unwind): Use it.
642 * lisp.h (free_save_value): New prototype.
643 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
645 (save_excursion_restore): Adjust to match saved data structure.
646 Use free_save_value to offload some work from GC. Drop obsolete
649 2012-12-03 Chong Yidong <cyd@gnu.org>
651 * fileio.c (Vauto_save_list_file_name): Doc fix.
653 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
655 * w32fns.c: Remove prototype of atof.
656 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
658 (file_dialog_callback): Make it UINT_PTR.
660 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
663 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
664 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
667 2012-12-03 Glenn Morris <rgm@gnu.org>
669 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
671 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
673 Fix xpalloc confusion after memory is exhausted.
674 * alloc.c (xpalloc): Comment fix.
675 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
676 and signals an error, do not clear charset_table_size, as
677 charset_table is still valid.
678 * doprnt.c (evxprintf): Clear *BUF after freeing it.
680 Use execve to avoid need to munge environ (Bug#13054).
681 * callproc.c (Fcall_process):
682 * process.c (create_process):
683 Don't save and restore environ; no longer needed.
684 * callproc.c (child_setup):
685 Use execve, not execvp, to preserve environ.
687 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
689 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
691 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
693 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
694 display for sliced images (Bug#10500).
696 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.

701 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
703 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
705 * xdisp.c (window_outdated): Remove eassert since it hits
706 some suspicious corner cases (see Bug#13007 and Bug#13012).
707 (mode_line_update_needed): New function.
708 (redisplay_internal, redisplay_window): Use it.
709 (ensure_selected_frame): New function.
710 (redisplay_internal, unwind_redisplay): Use it.
711 (redisplay_internal): Move comment about buffer_shared...
712 (buffer_shared_and_changed): ...near to its real use.
714 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>

718 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
720 * callproc.c (Fcall_process): Fix vfork portability problems.
721 Do not assume that fd[0], count, filefd, and save_environ survive
722 vfork. Fix bug whereby wrong errno value could be reported for
723 pipe failure. Some minor cleanups, too, as follows. Move buf and
724 bufsize to the context where they're needed. Change new_argv to
725 be of type char **, as this is more convenient and avoids casts.
726 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
727 Now local constants, not macros.
729 2012-11-18 Kenichi Handa <handa@gnu.org>
731 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
732 for the variable "f".
734 2012-11-13 Kenichi Handa <handa@gnu.org>
736 * font.c (font_unparse_xlfd): Exclude special characters from the
737 generating XLFD name.

779 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
780 between bpos_covered and bpos_max. This fixes cursor display when
781 several display strings follow each other.
783 * .gdbinit (pgx): If the glyph's object is a string, display the
784 pointer to string data, rather than the value of the string object
785 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
787 * indent.c (Fvertical_motion): If the starting position is covered
788 by a display string, return to one position before that, to avoid
789 overshooting it inside move_it_to. (Bug#12930)

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

851 (update_menu_bar, update_tool_bar): Use it to
852 simplify large 'if' statements.

887 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
888 Define for the MSVC compiler.
890 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
892 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
893 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
894 dostounix_filename. Prevents crashes down the road, because
895 dostounix_filename assumes it gets a unibyte string.

977 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
979 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
980 * callproc.c (relocate_fd): Assume F_DUPFD.
981 * emacs.c, term.c (O_RDWR): Remove.
982 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
983 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
984 * nsterm.m: Assume <fcntl.h> exists.
985 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
986 (create_pty, Fmake_network_process, server_accept_connection)
987 (wait_reading_process_output, init_process_emacs):
989 (wait_reading_process_output): Put in a special case for WINDOWSNT
990 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
991 It's not clear this is needed, but it's a more-conservative change.
992 (create_process): Assume FD_CLOEXEC.
993 (create_process, create_pty): Assume O_NOCTTY.
994 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
995 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
996 Omit if not DOS_NT, since F_GETFL is not defined there.
997 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
998 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1000 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1001 lack it, since gnulib guarantees this.
1002 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1004 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1006 * w32.c (faccessat): Pretend that directories have the execute bit
1007 set. Emacs expects that, e.g., in files.el:cd-absolute.
1009 * w32proc.c (create_child): Don't clip the PID of the child
1010 process to fit into an Emacs integer, as this is no longer a
1012 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1013 reaping only the process specified by PID argument, if that is
1014 positive. Use PID instead of dead_child to know which process to
1015 reap. Wait for the child to die only if WNOHANG is not in
1017 (sys_select): Don't set dead_child.
1019 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1020 as it is no longer needed.
1022 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1024 (record_child_status_change): Remove the setting of
1025 record_at_most_one_child for the !WNOHANG case.
1027 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1029 Fix problems in ns port found by static checking.
1030 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1031 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1032 not to process group.
1033 (ns_select): Use emacs_write, not write, as that's more robust
1034 in the presence of signals.
1035 (fd_handler:): Check for read errors.
1037 2012-11-16 Glenn Morris <rgm@gnu.org>
1039 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1041 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1043 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1045 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1047 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1048 use the same value of thread handle.
1049 (start_timer_thread): If the timer thread exited (due to error),
1050 clean up by closing the two handles it used. Duplicate the caller
1051 thread's handle here, so it gets duplicated only once, when
1052 launching the timer thread. Set priority of the timer thread, not
1054 (getitimer): Don't duplicate the caller thread's handle here.
1057 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1059 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1062 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1064 Remove no-longer-used pty_max_bytes variable.
1065 * process.c (pty_max_bytes): Remove; unused.
1066 (send_process): Do not set it.
1068 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1070 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1071 Update dependencies.
1073 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1075 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1076 This follows up on the 2012-09-29 patch that removed indirection
1077 for the 'function' field. Reported by Sergey Vinokurov in
1078 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1080 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1082 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1083 different name, as the MS runtime does not have such a function,
1084 and probably never will.) All callers changed. Ignore DIRFD
1085 value if PATH is an absolute file name, to match Posix spec
1086 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1089 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1091 * xdisp.c (echo_area_display, redisplay_internal):
1092 Omit redundant check whether frame_garbaged is set.
1094 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1096 Use faccessat, not access, when checking file permissions (Bug#12632).
1097 This fixes a bug that has been present in Emacs since its creation.
1098 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1099 which must set some sort of record. (Torek's bug report was against
1100 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1101 same common flaw.) See Torek's Usenet posting
1102 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1103 Posted: Fri Apr 8 14:18:56 1983.
1104 * Makefile.in (LIB_EACCESS): New macro.
1106 * callproc.c (init_callproc):
1107 * charset.c (init_charset):
1108 * fileio.c (check_existing, check_executable, check_writable)
1110 * lread.c (openp, load_path_check):
1111 * process.c (allocate_pty):
1113 Use effective UID when checking permissions, not real UID.
1114 * callproc.c (init_callproc):
1115 * charset.c (init_charset):
1116 * lread.c (load_path_check, init_lread):
1117 Test whether directories are accessible, not merely whether they exist.
1118 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1119 * fileio.c (check_existing, check_executable, check_writable)
1121 Use symbolic names instead of integers for the flags, as they're
1123 (check_writable): New arg AMODE. All uses changed.
1124 Set errno on failure.
1125 (Ffile_readable_p): Use faccessat, not stat + open + close.
1126 (Ffile_writable_p): No need to call check_existing + check_writable.
1127 Just call check_writable and then look at errno. This saves a syscall.
1128 dir should never be nil; replace an unnecessary runtime check
1129 with an eassert. When checking the parent directory of a nonexistent
1130 file, check that the directory is searchable as well as writable, as
1131 we can't create files in unsearchable directories.
1132 (file_directory_p): New function, which uses 'stat' on most platforms
1133 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1134 (Ffile_directory_p, Fset_file_times): Use it.
1135 (file_accessible_directory_p): New function, which uses a single
1136 syscall for efficiency.
1137 (Ffile_accessible_directory_p): Use it.
1138 * xrdb.c (file_p): Use file_directory_p.
1139 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1140 * lread.c (openp): When opening a file, use fstat rather than
1141 stat, as that avoids a permissions race. When not opening a file,
1142 use file_directory_p rather than stat.
1143 (dir_warning): First arg is now a usage string, not a format.
1144 Use errno. All uses changed.
1145 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1146 that merely introduced a race.
1147 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1148 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1149 and similarly for the other O_* flags.
1150 * w32.c (sys_faccessat): Rename from sys_access and switch to
1151 faccessat's API. All uses changed.
1152 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1153 (magic_db): Rename from magic_file_p.
1154 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1155 char *, so that we don't have to test for file existence
1156 separately from opening the file for reading. This removes a race
1157 fixes a permission-checking problem, and simplifies the code.
1159 (file_p): Remove; no longer needed.
1161 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1163 Omit glyphs initialization at startup.
1164 * dispnew.c (glyphs_initialized_initially_p): Remove.
1165 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1166 (Fredraw_frame): Move actual code from here...
1167 (redraw_frame): ...to here. Add eassert. Adjust comment.
1168 (Fredraw_display): Use redraw_frame.
1169 * xdisp.c (clear_garbaged_frames): Likewise.
1171 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1173 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1174 passed to pint2str and pint2hrstr to be at most the size of the
1175 frame's decode_mode_spec_buffer. This avoids crashes with very
1176 large values of FIELD_WIDTH argument to decode_mode_spec.
1179 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1181 Fix a race with verify-visited-file-modtime (Bug#12863).
1182 Since at least 1991 Emacs has ignored an mtime difference of no
1183 more than one second, but my guess is that this was to work around
1184 file system bugs that were fixed long ago. Since the race is
1185 causing problems now, let's remove that code.
1186 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1187 whose time stamp is off by no more than a second. Insist that the
1188 file time stamps match exactly.
1190 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1192 * frame.h (struct frame): Convert external_tool_bar member to
1193 1-bit unsigned bitfield.
1194 * termhooks.h (struct terminal): Remove mouse_moved member since
1195 all users are long dead. Adjust comment on mouse_position_hook.
1197 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1199 Simplify by using FOR_EACH_FRAME here and there.
1200 * frame.c (next_frame, prev_frame, other_visible_frames)
1201 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1202 * w32term.c (x_window_to_scroll_bar): Likewise.
1203 * window.c (window_list): Likewise.
1204 * xdisp.c (x_consider_frame_title): Likewise.
1205 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1206 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1207 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1208 * xmenu.c (menubar_id_to_frame): Likewise.
1209 * xselect.c (frame_for_x_selection): Likewise.
1210 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1211 (x_window_to_menu_bar): Likewise.
1212 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1214 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1216 * data.c (Qdefalias_fset_function): Now static.
1218 Another tweak to vectorlike_header change.
1219 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1220 Remove, and replace all uses with ...
1221 (next_in_free_list, set_next_in_free_list):
1222 New functions, which respect C's aliasing rules better.
1224 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1226 * window.c (list4i): Rename from 'quad'. All uses changed.
1227 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1229 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1231 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1232 warning about mixing declarations and code in ISO C90.
1234 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1236 * window.c (Fsplit_window_internal): Set combination limit of
1237 new parent window to t iff Vwindow_combination_limit is t;
1238 fixing a regression introduced with the change from 2012-09-22.
1239 (Fset_window_combination_limit): Fix doc-string.
1241 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1243 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1244 amount when the scroll margins are too large. When scrolling
1245 backwards in the buffer, give up if cannot reach point or the
1246 scroll margin within a reasonable number of screen lines.
1247 Fixes point position in window under scroll-up/down-aggressively when
1248 point is positioned many lines beyond the window top/bottom.
1251 * ralloc.c (relinquish): If real_morecore fails to return memory
1252 to the system, don't crash; instead, leave the last heap
1253 unchanged and return. (Bug#12774)
1255 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1257 * lisp.h (AUTOLOADP): New macro.
1258 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1259 * data.c (Ffset): Remove special ad-advice-info handling.
1260 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1262 (Finteractive_form): Simplify.
1263 (Fquo): Don't insist on having at least 2 arguments.
1264 (Qdefalias_fset_function): New var.
1266 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1268 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

1274 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1276 Fix recently introduced crash on MS-Windows (Bug#12839).
1277 * w32term.h (struct scroll_bar): Use convenient header.
1278 (SCROLL_BAR_VEC_SIZE): Remove.
1279 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1281 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1283 Tweak last vectorlike_header change.
1284 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1285 vectorlike object on the free list. This is introduced to avoid
1286 some (but not all) pointer casting and aliasing problems, see
1287 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1288 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1290 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1292 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1294 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1295 been removed, so remove them here also.
1297 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1299 * doc.c (Fdocumentation): Handle new property
1300 dynamic-docstring-function to replace the old ad-advice-info.
1302 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>

1313 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1315 Use same hash function for hashfn_profiler as for hash_string etc.
1316 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1317 * lisp.h (sxhash_combine): New inline function, with the contents
1318 of the old SXHASH_COMBINE.
1319 * profiler.c (hashfn_profiler): Use it, instead of having a
1320 special hash function containing a comparison that always yields 1.
1322 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1324 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1325 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1326 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1329 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1331 * image.c (xpm_make_color_table_h): Fix compiler error because

1341 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1342 (make_log): Use them.

1354 (hash_lookup, hash_remove_from_table): Move assertion checking of
1355 hashfn result here. Check hash-equality before calling cmpfn.

1367 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1368 value of w32-scroll-lock-modifier is neither nil nor one of the
1369 known key modifiers. (Bug#12806)
1371 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>

1374 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1376 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

1395 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1396 (large_vectors): Change type to struct large_vector.
1397 (allocate_vector_from_block): Simplify.
1398 (PSEUDOVECTOR_NBYTES): Replace with...

1408 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1410 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1411 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1412 (copy_hash_table): Adjust to match vector header change.
1413 * lread.c (defsubr): Use XSETPVECTYPE.
1414 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
1415 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1416 (xvecsize): New command.
1418 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1420 * keyboard.c (event_to_kboard): Do not dereference
1421 frame_or_window field of SELECTION_REQUEST_EVENT
1422 and SELECTION_CLEAR_EVENT events (Bug#12814).
1423 * xterm.h (struct selection_input_event): Adjust comment.
1425 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1427 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1428 such as Scroll Lock, if the respective keys are treated as
1429 function keys, not as modifiers. This avoids destroying non-ASCII
1430 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1432 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1434 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1436 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1438 Restore some duplicate definitions (Bug#12814).
1439 This undoes part of the 2012-11-03 changes. Some people build
1440 with plain -g rather than with -g3, and they need the duplicate
1441 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1442 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1443 Define as macros, as well as as enums or as constants.
1445 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1447 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1448 to keypad keys (Bug#12816).
1450 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1452 Minor adjustments of recently-changed frame functions.
1453 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1454 known to be a frame (we're in the FRAMEP branch).
1455 * lisp.h (Qframep): Remove decl. frame.h declares this.
1456 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1457 since they're meant for Lisp fixnum values.
1459 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1461 * window.c (Fwindow_combination_limit): Revert to the only
1462 required argument and adjust docstring as suggested in
1463 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1464 by Martin Rudalics <rudalics@gmx.at>.
1466 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1468 Widely used frame validity and checking functions.
1469 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1470 * frame.c (decode_live_frame, decode_any_frame): New functions.
1471 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1472 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1473 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1474 (Fframe_pointer_visible_p): Use decode_any_frame.
1475 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
1476 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1477 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1478 (Fframe_focus): Likewise. Allow zero number of arguments.
1480 (frame_buffer_list, frame_buffer_predicate): Remove.
1481 * lisp.h (frame_buffer_predicate): Remove prototype.
1482 * buffer.c (Fother_buffer): Use decode_any_frame.
1483 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1484 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1485 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1486 (Fclose_font, Ffont_info): Use decode_live_frame.
1487 * fontset.c (check_fontset_name): Likewise.
1488 * terminal.c (Fframe_terminal): Likewise.
1489 * w32fns.c (check_x_frame): Likewise.
1490 * window.c (Fminibuffer_window, Fwindow_at)
1491 (Fcurrent_window_configuration): Likewise.
1492 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1493 Likewise. Allow zero number of arguments. Adjust docstring.
1494 * dispnew.c (Fredraw_frame): Likewise.
1495 * xfaces.c (frame_or_selected_frame): Remove.
1496 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1497 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1498 (Fframe_face_alist): Use decode_live_frame.
1499 * xfns.c (check_x_frame): Likewise.
1501 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1503 * window.c (quad): New function.
1504 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1505 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1506 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1507 (Fwindow_line_height): Use it.
1508 (Fwindow_fringes): Use list3.
1509 (Fwindow_scroll_bars): Use list4.
1510 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1511 (Fwindow_combination_limit): Allow zero number of arguments.
1513 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1515 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1517 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1518 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1519 file descriptor 2 for standard error. (Bug#12805)
1521 2012-11-05 Chong Yidong <cyd@gnu.org>
1523 * process.c (wait_reading_process_output): Revert previous change.
1525 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1527 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1528 This removes code that has been obsolete since around 1990.
1529 * callproc.c (Fcall_process):
1531 * process.c (create_process):
1532 * term.c (dissociate_if_controlling_tty):
1533 Assume setsid exists.
1534 * callproc.c (child_setup): Assume setpgid exists and behaves as
1535 per POSIX.1-1988 or later.
1536 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1537 * emacs.c (shut_down_emacs):
1538 * sysdep.c (sys_suspend, init_foreground_group):
1539 Assume getpgrp behaves as per POSIX.1-1998 or later.
1540 * msdos.c (setpgrp): Remove.
1541 (tcgetpgrp, setpgid, setsid): New functions.
1542 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1543 * term.c (no_controlling_tty): Remove; unused.
1544 * w32proc.c (setpgrp): Remove.
1545 (setsid, tcgetpgrp): New functions.
1547 Simplify by assuming __fpending.
1548 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1549 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1550 Do not assume that __fpending's result fits in int.
1552 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1554 Remove EMACS_OUTQSIZE+sleep hack.
1555 * dispnew.c (update_frame_1): Remove hack for terminals slower
1556 than 2400 bps, which throttled Emacs by having it sleep.
1557 This code hasn't worked since at least 2007, when the multi-tty stuff
1558 was added, and anyway those old terminals are long dead.
1559 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1560 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1562 Fix data-loss with --version (Bug#9574).
1563 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1564 as we can't assume that emacs_strerror is initialized, and strerror
1565 is good enough here.
1566 (main): Invoke atexit earlier, to catch earlier instances of
1567 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1569 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1571 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1572 (keyDown): Remap keypad keys to X11 virtual key codes.
1574 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1576 Fix data-loss with --batch (Bug#9574).
1577 * emacs.c: Include <close-stream.h>.
1578 (close_output_streams): New function.
1579 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1580 and handles errors appropriately.
1581 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1584 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1585 The symptom is a diagnostic "GLib-WARNING **: In call to
1586 g_spawn_sync(), exit status of a child process was requested but
1587 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1588 waitpid(), so exit status can't be returned." The diagnostic
1589 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1590 The real bug is a race condition between Emacs and glib: Emacs
1591 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1592 so that glib can't find it. Work around the bug by invoking
1593 waitpid only on subprocesses that Emacs itself creates.
1594 * process.c (create_process, record_child_status_change):
1595 Don't use special value -1 in pid field, as the caller now must
1596 know the pid rather than having the callee infer it.
1597 The inference was sometimes incorrect anyway, due to another race.
1598 (create_process): Set new 'alive' member if child is created.
1599 (process_status_retrieved): New function.
1600 (record_child_status_change): Use it.
1601 Accept negative 1st argument, which means to wait for the
1602 processes that Emacs already knows about. Move special-case code
1603 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1604 processes that have already been waited for, by testing and
1605 clearing new 'alive' member.
1606 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1607 now does this internally.
1608 (handle_child_signal): Let record_child_status_change do all
1609 the work, since we do not want to reap all exited child processes,
1610 only the child processes that Emacs itself created.
1611 * process.h (Lisp_Process): New boolean member 'alive'.
1613 Omit duplicate definitions no longer needed with gcc -g3.
1614 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1615 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1616 Define only as macros. There's no longer any need to also define
1617 these symbols as enums or as constants, since we now assume
1618 gcc -g3 when debugging.
1620 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1622 * lisp.mk: Adjust comments to the fact that term/internal is now
1623 loaded from loadup.el.
1625 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1626 (msdos_fatal_signal): New function.
1627 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1630 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1631 for GCC versions before 4.
1632 (emacs_raise): Define to call msdos_fatal_signal.
1634 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1635 iterator when starting in the middle of a display or overlay
1638 2012-11-03 Chong Yidong <cyd@gnu.org>
1640 * process.c (wait_reading_process_output): Clean up the last
1643 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1645 * process.c (wait_reading_process_output): Avoid a race condition
1646 with SIGIO delivery (Bug#11536).
1648 2012-11-03 Chong Yidong <cyd@gnu.org>
1650 * buffer.c (cursor_type): Untabify docstring.
1652 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1654 * frame.h (struct frame): Drop can_have_scroll_bars member
1655 which is meaningless for a long time. Adjust comments.
1656 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1657 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1659 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1661 * window.c (decode_next_window_args): Update window arg after
1662 calling decode_live_window and so fix crash reported at
1663 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1664 by Juanma Barranquero <lekktu@gmail.com>.
1665 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1666 * font.c (Ffont_at): Likewise.
1668 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1670 * widget.c (resize_cb): New function.
1671 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1672 (EmacsFrameResize): Check if all is up to date before changing frame
1675 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1677 Implement backtrace output for fatal errors on MS-Windows.
1678 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1679 (BACKTRACE_LIMIT_MAX): New macro.
1680 (w32_backtrace): New function.
1681 (emacs_abort): Use w32_backtrace when the user chooses not to
1682 attach a debugger. Update the text of the abort dialog.
1684 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1686 Window-related stuff cleanup here and there.
1687 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1688 Use decode_any_window.
1689 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1690 * xdisp.c (Fformat_mode_line): Likewise.
1691 * font.c (Ffont_at): Use decode_live_window.
1692 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1693 * window.c (decode_next_window_args): Likewise.
1694 (decode_any_window): Remove static.
1695 * window.h (decode_any_window): Add prototype.
1696 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1697 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1700 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1702 Remove pad from struct input_event.
1703 * termhooks.h (struct input_event): Remove padding field.
1705 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1706 member is never cons for a long time. Adjust comment.
1707 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1708 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1709 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1710 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1712 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1714 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1716 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1718 Fix crash when using Emacs as commit editor for git (Bug#12697).
1719 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1720 and it is configured in conf_post.h.
1721 (Fcall_process): Don't invoke both setsid and setpgid; the former
1722 is enough, if it exists.
1723 * callproc.c (Fcall_process, child_setup):
1724 * process.c (create_process): Use setpgid.
1725 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1727 * dispnew.c (init_display): Initialize the foreground group
1728 if we are running a tty display.
1729 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1730 * lisp.h (init_foreground_group): New decl.
1731 * sysdep.c (inherited_pgroup): New static var.
1732 (init_foreground_group, tcsetpgrp_without_stopping)
1733 (narrow_foreground_group, widen_foreground_group): New functions.
1734 (init_sys_modes): Narrow foreground group.
1735 (reset_sys_modes): Widen foreground group.
1737 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1739 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1741 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1743 * minibuf.c (read_minibuf): Restore current buffer since
1744 choose_minibuf_frame calling Fset_frame_selected_window may
1745 change it (Bug#12766).
1747 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1749 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1751 2012-10-30 Kenichi Handa <handa@gnu.org>
1753 * font.c (Ffont_at): If WINDOW is specified and it is not
1754 displaying the current buffer, signal an error.
1756 2012-10-29 Daniel Colascione <dancol@dancol.org>
1758 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1759 In preparation for fixing bug#12739, move these functions from
1762 * coding.h, coding.c: ... to here, and compile them only when
1763 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1764 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1766 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1768 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1769 (timer_loop, getitimer, setitimer): Use it instead of
1770 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1772 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1775 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1777 * nsterm.m (NO_APPDEFINED_DATA): New define.
1778 (last_appdefined_event_data): New variable
1779 (last_appdefined_event): Remove.
1780 (ns_select): Initialize t from last_appdefined_event_data instead
1781 of [last_appdefined_event data1].
1782 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1783 remove last_appdefined_event (Bug#12698).
1785 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1787 * frame.c (x_set_font): Catch internal error.
1789 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1791 Avoid overflow in w32 implementation of interval timers.
1792 When possible, for ITIMER_PROF count only times the main thread
1794 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1795 'volatile ULONGLONG' types. All the other data which was
1796 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1797 (GetThreadTimes_Proc): New typedef.
1798 (w32_get_timer_time): New function, returns a suitable time value
1800 (timer_loop): Enter critical section when accessing ULONGLONG
1801 values of the itimer_data struct, as these accesses are no longer
1802 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1803 Remove unused variable.
1804 (init_timers): Initialize s_pfn_Get_Thread_Times.
1805 (start_timer_thread): Don't assign itimer->caller_thread here.
1806 (getitimer): Assign itimer->caller_thread here.
1807 (setitimer): Always call getitimer to get the value of ticks_now.
1808 (sys_spawnve): Avoid compiler warning about format mismatch.
1810 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1812 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1813 mouse movement events if the menu bar is active. This avoids
1814 producing a busy "hour-glass" cursor by Windows if the mouse
1815 pointer is positioned over a tooltip shown for some menu item.
1817 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1819 Don't assume process IDs fit in int.
1820 * emacs.c (shut_down_emacs) [!DOS_NT]:
1821 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1822 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1823 Use pid_t, not int, to store process IDs, as 'int'
1824 is not wide enough on a few platforms (e.g., AIX and IRIX).
1826 2012-10-23 Kenichi Handa <handa@gnu.org>
1828 The following change is to make face-font-rescale-alist work
1829 correctly for non-ASCII fonts.
1831 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1832 (font_open_for_lface): Handle Vface_font_rescale_alist.
1834 2012-10-23 Chong Yidong <cyd@gnu.org>
1836 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1838 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1840 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1842 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1844 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1847 2012-10-21 Glenn Morris <rgm@gnu.org>
1849 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1851 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1853 Port to OpenBSD 5.1.
1854 * frame.c (Fmouse_position, Fmouse_pixel_position):
1855 * xdisp.c (produce_stretch_glyph):
1856 Declare local vars only when they're needed.
1857 This is clearer and avoids a warning on OpenBSD about unused vars.
1858 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1859 This is safer, and avoids OpenBSD warnings about unused vars.
1860 * keyboard.c (record_menu_key): Remove unnecessary decl.
1861 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1862 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1863 as our definition clashes with OpenBSD's.
1864 * xfaces.c (load_face_colors, check_lface_attrs)

2342 W32_OBJ and W32_LIBS. Compile new files.
2345 (_DebPrint) declare tracing facility for W32 debugging. We need
2346 to unify tracing later.
2348 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2349 unconditional use of W32 Unicode functions. Cygwin runs only on
2350 100% Unicode operating systems.
2352 * cygw32.c: New file. Define Cygwin-specific facilities.
2353 (Fcygwin_convert_path_to_windows)
2354 (Fcygwin_convert_path_from_windows): New user functions for
2355 accessing Cygwin path-munging routines.
2357 * cygw32.h: New file.
2358 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2359 UTF-16LE strings temporarily inside non-Lisp-visible string
2362 (w32_strerror): Just what it says on the tin.
2364 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2365 also run for Cygwin; both systems have the same problem with using
2366 GUI facilities in a forked child. Also call syms_of_cygw32,
2367 syms_of_w32select in correct places.
2369 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2370 needs fork-then-exec for daemon launching.
2372 * font.h: Include frame.h.
2374 * image.c: Use the image library cache machinery only when we're
2375 compiling for native WINDOWSNT; Cygwin can use shared libraries
2376 like any other Unixlike system.
2378 * keyboard.c: Clarify a comment regarding the input loop.
2380 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2381 functions directly instead of trying to detect at runtime that our
2382 host operating system supports them. We make this change for two
2383 reasons: Cygwin lacks support for the multibyte character
2384 conversion functions used by the legacy menu code, and Cygwin
2385 never needs to rely on non-Unicode APIs.
2387 * unexw32.c (hinst): Declare extern.
2389 * w32.c: Change header order;
2390 (w32_strerror): Move to w32fns.c because we need it for
2391 non-WINDOWSNT builds.
2393 * w32.h: Add #error macro to make sure we don't include w32.h for
2394 Cygwin builds. Remove w32select declarations.
2396 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2397 w32fns.c. w32console.c is WINDOWSNT-only.
2399 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2400 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2402 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2403 (w32_major_version, w32_minor_version, w32_build_number)
2404 (os_subtype, sound_type): Define here
2405 (w32_defined_color): Make color parameter const for consistency
2406 with other _defined_color functions.
2407 (w32_createwindow): Unconditionally call w32_init_class instead of
2408 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2409 through the code is complex and unnecessary because class
2410 registration is practically free.
2411 (w32_name_of_message): New EMACSDEBUG-only function.
2412 (Fset_message_beep): Move here
2413 (Fx_open_connection): Require that the display name for Windows be
2414 "w32" for consistency, emacsclient disambiguation, and maybe, one
2415 day, multi-window-system support.
2416 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2417 Cygwin files for W32 GUI facilities, since these clearly don't
2418 expect Cygwin names.
2419 (_DebPrint): Define.
2420 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2421 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2422 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2423 (w32_last_error): Remove.
2425 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2427 * w32heap.c (syspage_mask): Declare here.
2428 (cache_system_info): Remove.
2430 * w32inevt.c (faked_key): Define globally, not statically.
2431 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2432 (w32_console_toggle_lock_key): Move to w32fns.c.
2434 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2436 * w32proc.c (_DebPrint): Move to w32fns.c.
2437 * w32select.c: Include string.h, stdio.h for Cygwin.
2438 * w32select.h: New File.
2440 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2442 (w32_message_fd): New variable. Under Cygwin, holds the file
2443 descriptor the system used to tell us about pending thread
2446 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2447 that prevented compilation under non-WINDOWSNT systems.
2449 (w32_initialize): Open /dev/windows and assign it to
2450 w32_message_fd. Provide w32 feature.
2452 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2453 (WM_EMACS_INPUT_READY): add.
2454 (prepend_msg, w32_message_fd): Declare globally.
2457 (keyboard_handle): Use only when WINDOWSNT.
2458 (notify_msg_ready): New function. Posts a message to the main
2459 thread's message queue under CYGWIN, which wakes up the main
2460 thread from select(2) by making the /dev/windows file descriptor
2461 ready. Under WINDOWSNT, it sets an event the same way the old
2464 (post, prepend_msg): Actually call notify_msg_ready instead of
2465 setting the input event directly.
2467 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2469 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2470 but it still has blocs in it, don't return it to the system,
2471 instead of aborting. (Bug#12402)
2473 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2475 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2477 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2478 MAC_OS_X_VERSION_10_6.
2479 (syms_of_nsterm): Remove comment about Panther and above for
2481 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2482 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2483 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2485 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2486 MAC_OS_X_VERSION_10_4.
2488 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2489 MAC_OS_X_VERSION_10_2.
2491 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2493 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2494 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2496 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2497 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2498 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2499 Remove ns_in_resize check.
2500 (ns_clear_frame_area): Remove resize handle code.
2502 * nsfns.m (ns_in_resize): Remove.
2503 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2504 Remove ns_in_resize check.
2506 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2508 Improve sys_siglist detection.
2509 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2510 defined as a macro, as is done in Solaris.
2511 (sys_siglist_entries): New macro.
2512 (save_strsignal): Use it.
2513 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2514 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2516 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2518 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2519 fullscreen/Fullscreen.
2521 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2522 tobar_height is new.
2524 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2525 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2526 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2527 (windowDidResize:): Check for correct window if old style fullscreen.
2528 Capitalize word in comment. Remove incorrect comment.
2529 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2530 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2531 error in drawing background.
2532 (toggleFullScreen:): Remove comment. Rearrange calls.
2533 Set toolbar values to zero, save old height in tobar_height.
2534 Restore tool bar height when leaving fullscreen.
2535 (canBecomeMainWindow): New function.
2537 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2539 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2541 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2543 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2545 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2546 that time stamps of directories could also be changed.
2547 Don't request the too broad GENERIC_WRITE, only the more restrictive
2548 FILE_WRITE_ATTRIBUTES access rights.
2550 * fileio.c (Fset_file_times): Special-case ignoring errors for
2551 directories only on MSDOS, not on MS-Windows.
2553 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2555 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2557 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2559 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2560 see whether CreateFile failed.
2562 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2564 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2565 to avoid similar races.
2566 * keyboard.c (pending_signals): Now bool, not int.
2568 Port timers to OpenBSD, plus check for timer failures.
2569 OpenBSD problem reported by Han Boetes.
2570 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2572 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2573 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2574 like OpenBSD, which has timer_settime but does not declare it.
2575 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2576 whether to use itimerspec-related primitives. All uses of
2577 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2579 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2581 * profiler.c (handle_profiler_signal): Fix a malloc race
2582 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2584 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2586 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2588 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2590 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2591 consistent with the change in return value of 'safe_strsignal'.
2593 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2595 Prefer plain 'static' to 'static inline' (Bug#12541).
2596 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2597 (bidi_set_sor_type, bidi_push_embedding_level)
2598 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2599 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2600 (bidi_cache_search, bidi_cache_ensure_space)
2601 (bidi_cache_iterator_state, bidi_cache_find)
2602 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2603 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2604 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2605 Now 'static', not 'static inline'.
2607 Count overruns when profiling; change units to ns.
2608 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2609 Give extra weight to samples after overruns, to attempt to count
2610 the time more accurately.
2611 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2612 the underlying primitives nominally do ns.
2613 (Fprofiler_cpu_start): Document the change. Mention that
2614 the sampling intervals are only approximate.
2616 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2618 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2620 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2621 case for the special 0 coding-system.
2623 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2624 (Fmake_overlay): Remove redundant tests.
2625 (fix_start_end_in_overlays): Remove redundant recentering.
2627 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2629 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2630 Update dependencies.
2632 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2634 Fix a malloc race condition involving strsignal.
2635 A signal can arrive in the middle of a malloc, and Emacs's signal
2636 handler can invoke strsignal, which can invoke malloc, which is
2637 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2638 Fix it by altering the signal handler so that it does not invoke
2640 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2641 * process.c (status_message): Use const pointer, in case strsignal
2642 is #defined to safe_strsignal.
2643 * sysdep.c (sys_siglist, init_signals): Always define and
2644 initialize a substitute sys_siglist if the system does not define
2645 one, even if HAVE_STRSIGNAL.
2646 (safe_strsignal): Rename from strsignal. Always define,
2647 using sys_siglist. Return a const pointer.
2648 * syssignal.h (safe_strsignal): New decl.
2649 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2651 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2653 * w32proc.c (timer_loop): Fix code that waits for timer
2654 expiration, to avoid high CPU usage.
2656 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2658 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2659 (sweep_weak_table): Remove redundant prototypes.
2661 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2663 * emacs.c: Move the inclusion of TERM_HEADER after including
2664 windows.h on WINDOWSNT. This avoids compilation problems with
2667 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2669 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2670 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2671 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2672 as the previous version used 'void *'.
2674 * ralloc.c (ROUNDUP): Fix last change.
2675 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2678 * w32proc.c <disable_itimers>: New static flag.
2679 (init_timers): Initialize it to zero, after creating the critical
2680 sections used by the timer threads.
2681 (term_timers): Set to 1 before deleting the critical sections.
2682 (getitimer, setitimer): If disable_itimers is non-zero, return an
2683 error indication without doing anything. Reported by Fabrice
2684 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2685 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2687 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2690 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2691 term_ntproc after all the other bookkeeping, to get timers working
2692 as long as possible.
2694 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2696 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2697 Suggested by Juri Linkov in
2698 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2700 Prefer plain 'static' to 'static inline' (Bug#12541).
2701 With static functions, modern compilers inline pretty well by
2702 themselves; advice from programmers often hurts as much as it helps.
2703 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2704 this change shrinks the text size of the Emacs executable by 1.1%
2705 without affecting CPU significantly in my benchmark.

2791 * dired.c (directory_files_internal, Ffile_attributes):
2794 * frame.c (x_report_frame_params): Port better to wider ints.
2795 Do not assume that EMACS_UINT is the same width as uprintmax_t,

2999 (handle_profiler_signal): Rename from sigprof_handler_1,
3000 for consistency with other handlers. Do not check whether
3001 cpu_log is a hash-table if garbage collecting, since it

3004 for consistency with other handlers.
3005 (setup_cpu_timer): New function, with much of what used to be in

3007 Prefer timer_settime if available, and prefer
3008 thread cputime clocks, then process cputime clocks, then
3009 monotonic clocks, to the old realtime clock. Use make_timeval
3010 to round more-correctly when falling back to setitimer.
3011 (Fprofiler_cpu_start): Use it.
3012 (Fprofiler_cpu_stop): Prefer timer_settime if available.

3282 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3284 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3285 fatal_error_backtrace.
3287 * w32proc.c (sys_kill): Undo last change: don't do anything when
3288 invoked to deliver SIGABRT to our own process. This is now
3289 handled by emacs_raise.
3291 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3293 * w32term.c (w32_read_socket): Remove leftover reference to
3294 interrupt_input_pending.
3296 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3298 Do not use SA_NODEFER.
3299 Problem reported by Dani Moncayo in
3300 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3302 * sysdep.c (emacs_abort): Do not reset signal handler.
3303 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3304 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3305 wanted even on POSIXish hosts, and it doesn't work on Windows.
3307 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3309 * xterm.c (x_term_init): Call fixup_locale before and after calling
3310 gtk_init (Bug#12392).
3312 2012-09-23 Chong Yidong <cyd@gnu.org>
3314 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3315 Vdynamic_library_alist.
3317 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3318 (Fgnutls_available_p): Caller changed.
3320 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3321 (Flibxml_parse_xml_region): Likewise.
3323 * dispextern.h (struct image_type): Remove arg from init function.
3325 * image.c (Finit_image_library, lookup_image_type)
3326 (define_image_type): Remove now-unneeded second arg.
3327 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3328 (init_tiff_functions, init_gif_functions, init_svg_functions):
3329 Arglist and w32_delayed_load calling convention changed.
3330 (gs_type): Remove init_gs_functions; there is no such function.
3331 (valid_image_p, make_image): Fix caller to lookup_image_type.
3333 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3335 Simplify and avoid signal-handling races (Bug#12471).
3337 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3338 Avoid recursive loop if there's a fatal error in the function itself.
3339 * atimer.c (pending_atimers):
3340 * blockinput.h: Don't include "atimer.h"; no longer needed.
3341 (interrupt_input_pending): Remove. All uses removed.
3342 pending_signals now counts both atimers and ordinary interrupts.
3343 This is less racy than having three separate pending-signal flags.
3344 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3346 Rename from their upper-case counterparts BLOCK_INPUT,
3347 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3348 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3349 This makes it easier to access volatile variables more accurately.
3350 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3351 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3352 that's more reliable if the code is buggy and sets
3353 interrupt_input_blocked to a negative value. All uses changed.
3354 * atimer.c (deliver_alarm_signal):
3355 Remove. No need to deliver this to the parent; any thread can
3356 handle this signal now. All uses replaced by underlying handler.
3357 * atimer.c (turn_on_atimers):
3358 * dispnew.c (handle_window_change_signal):
3359 * emacs.c (handle_danger_signal):
3360 * keyboard.c (kbd_buffer_get_event):
3361 Don't reestablish signal handler; not needed with sigaction.
3362 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3364 Rework to avoid unnecessary accesses to volatile variables.
3365 (UNBLOCK_INPUT_TO): Now a function.
3366 (totally_unblock_input, unblock_input): New decls.
3367 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3368 (init_data): Remove. Necessary stuff now done in init_signal.
3369 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3370 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3371 (fatal_error_code): Remove; no longer needed.
3372 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3373 it doesn't always backtrace. All uses changed. No need to reset
3374 signal to default, since sigaction and/or die does that for us now.
3375 Use emacs_raise (FOO), not kill (getpid (), FOO).
3376 (main): Check more-accurately whether we're dumping.
3377 Move fatal-error setup to sysdep.c
3378 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3379 * gtkutil.c (xg_get_file_name, xg_get_font):
3380 Remove no-longer-needed signal-mask manipulation.
3381 * keyboard.c, process.c (POLL_FOR_INPUT):
3382 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3383 * keyboard.c (read_avail_input): Remove.
3384 All uses replaced by gobble_input.
3385 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3386 (kbd_buffer_store_event_hold, gobble_input):
3387 (record_asynch_buffer_change) [USABLE_SIGIO]:
3388 (store_user_signal_events):
3389 No need to mess with signal mask.
3390 (gobble_input): If blocking input and there are terminals, simply
3391 set pending_signals to 1 and return. All hooks changed to not
3392 worry about whether input is blocked.
3393 (process_pending_signals): Clear pending_signals before processing
3394 them, in case a signal comes in while we're processing.
3395 By convention callers now test pending_signals before calling us.
3396 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3397 New functions, to support changes to blockinput.h.
3398 (handle_input_available_signal): Now extern.
3399 (reinvoke_input_signal): Remove. All uses replaced by
3401 (quit_count): Now volatile, since a signal handler uses it.
3402 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3403 All callers changed. Block SIGINT only if not already blocked.
3404 Clear sigmask reliably, even if Fsignal returns, which it can.
3405 Omit unnecessary accesses to volatile var.
3406 (quit_throw_to_read_char): No need to restore sigmask.
3407 * keyboard.c (gobble_input, handle_user_signal):
3408 * process.c (wait_reading_process_output):
3409 Call signal-handling code rather than killing ourselves.
3410 * lisp.h: Include <float.h>, for...
3411 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3412 (pending_signals): Now volatile.
3413 (syms_of_data): Now const if IEEE floating point.
3414 (handle_input_available_signal) [USABLE_SIGIO]:
3415 (terminate_due_to_signal, record_child_status_change): New decls.
3416 * process.c (create_process): Avoid disaster if memory is exhausted
3417 while we're processing a vfork, by tightening the critical section
3419 (send_process_frame, process_sent_to, handle_pipe_signal)
3420 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3422 (send_process): No need for setjmp/longjmp any more, since the
3423 SIGPIPE stuff is now gone. Instead, report an error if errno
3425 (record_child_status_change): Now extern. PID and W are now args.
3426 Return void, not bool. All callers changed.
3427 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3428 Remove. All uses removed. This bug should be fixed now in a
3430 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3431 and record the child status change directly. This avoids the
3432 need to futz with the signal mask.
3433 (process_fatal_action): Move here from emacs.c.
3434 (emacs_sigaction_flags): New function, containing
3435 much of what used to be in emacs_sigaction_init.
3436 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3437 caught by emacs, to make races less likely.
3438 (deliver_process_signal): Rename from handle_on_main_thread.
3440 (BACKTRACE_LIMIT_MAX): Now at top level.
3441 (thread_backtrace_buffer, threadback_backtrace_pointers):
3443 (deliver_thread_signal, deliver_fatal_thread_signal):
3444 New functions, for more-accurate delivery of thread-specific signals.
3445 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3446 (deliver_arith_signal): Handle in this thread, not
3447 in the main thread, since it's triggered by this thread.
3448 (maybe_fatal_sig): New function.
3449 (init_signals): New arg DUMPING so that we can be more accurate
3450 about whether we're dumping. Caller changed.
3451 Treat thread-specific signals differently from process-general signals.
3452 Block all signals while handling fatal error; that's safer.
3453 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3455 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3456 Ignore SIGPIPE unless batch.
3457 (emacs_backtrace): Output backtrace for the appropriate thread,
3458 which is not necessarily the main thread.
3459 * syssignal.h: Include <stdbool.h>.
3460 (emacs_raise): New macro.
3461 * xterm.c (x_connection_signal): Remove; no longer needed
3462 now that we use sigaction.
3463 (x_connection_closed): No need to mess with sigmask now.
3464 (x_initialize): No need to reset SIGPIPE handler here, since
3465 init_signals does this for us now.
3467 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3469 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3470 background rect may be larger (Bug#12245).
3472 2012-09-23 Chong Yidong <cyd@gnu.org>
3474 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3476 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3478 * .gdbinit: Just stop at fatal_error_backtrace.
3479 See Stefan Monnier's request in
3480 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3481 Remove no-longer-used query of system type.
3483 2012-09-22 Chong Yidong <cyd@gnu.org>
3485 * search.c (Freplace_match): Doc fix (Bug#12325).
3487 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3489 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3490 (Fline_end_position): Doc fix.
3492 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3494 2012-09-22 Chong Yidong <cyd@gnu.org>
3496 * dispextern.h (struct image_type): Add new slot, storing a type
3497 initialization function.
3499 * image.c (define_image_type): Call the image initializer function
3500 if it is defined. Arguments and return value changed.
3501 (valid_image_p, make_image): Callers changed.
3502 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3503 (gif_type, imagemagick_type, svg_type, gs_type):
3504 Add initialization functions.
3505 (Finit_image_library): Call lookup_image_type.
3506 (CHECK_LIB_AVAILABLE): Macro deleted.
3507 (lookup_image_type): Call define_image_type here, rather than via
3508 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3509 (syms_of_image): Move define_image_type calls for xbm_type and
3510 pbm_type to lookup_image_type.
3512 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3514 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3515 'idle_timers' from here ...
3516 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3517 lists, to avoid infloops when the timer does something stupid,
3518 like reinvoke itself with the same or smaller time-out.
3521 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3523 * window.c (Fsplit_window_internal): Handle only Qt value of
3524 Vwindow_combination_limit separately.
3525 (Qtemp_buffer_resize): New symbol.
3526 (Vwindow_combination_limit): New default value.
3529 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3531 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3532 the new overlay string. (Bug#10159)
3534 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3536 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3537 or that fprintf is async-signal-safe. POSIX doesn't require
3540 2012-09-22 Chong Yidong <cyd@gnu.org>
3542 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3545 2012-09-22 Kenichi Handa <handa@gnu.org>
3547 * composite.c (composition_reseat_it): Handle the case that a
3548 grapheme cluster is not covered by a single font (Bug#12352).
3550 2012-09-21 Chong Yidong <cyd@gnu.org>
3552 * image.c (define_image_type): Avoid adding duplicate types to
3553 image_types (Bug#12463). Suggested by Jörg Walter.
3555 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3557 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3558 (print_load_command_name): Add case LC_DATA_IN_CODE.
3559 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3561 2012-09-21 Glenn Morris <rgm@gnu.org>
3563 * eval.c (Frun_hook_with_args_until_success)
3564 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3566 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3568 * fileio.c (Ffile_selinux_context): Only call freecon when
3569 lgetfilecon succeeded.
3570 (Fset_file_selinux_context): Likewise. (Bug#12444)
3572 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3574 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3575 reordering, locate the cursor by calling set_cursor_from_row; if
3576 that fails, clear the desired glyph matrix before returning a
3577 failure indication to the caller. Fixes leaving garbled display
3578 when fast scrolling with a down-key. (Bug#12403)
3579 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3580 scrolling through multibyte text.
3582 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3584 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3585 calling mark_vectorlike since that's the one that marks the window.
3586 (mark_discard_killed_buffers): Mark the final cdr.
3587 * window.h (struct window): Move prev/next_buffers to the
3588 non-standard fields.
3589 * window.c (make_window): Initialize prev/next_buffers manually.
3591 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3593 Omit unused arg EXPECTED from socket hooks.
3594 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3595 * nsterm.m (ns_term_init):
3596 * termhooks.h (struct terminal.read_socket_hook):
3597 * w32inevt.c (w32_console_read_socket):
3598 * w32term.c (w32_read_socket):
3599 * xterm.c (XTread_socket):
3600 Omit unused arg EXPECTED. All callers changed.
3601 (store_user_signal_events): Return void, not int, since callers no
3602 longer care about the return value. All uses changed.
3604 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3606 * w32gui.h (XParseGeometry): Do not declare.
3608 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3610 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3611 Ignore 'expected'. See Eli Zaretskii in
3612 <http://bugs.gnu.org/12471#8> (last line).
3614 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3615 (XParseGeometry): Now static. Substitute extremal values for
3616 values that are out of range.
3618 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3620 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3622 * nsfns.m (XParseGeometry): Remove.
3623 (Fx_create_frame): Call x_set_offset to correctly interpret
3624 top_pos in geometry.
3626 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3627 (Fx_parse_geometry): If there is a space in string, call
3628 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3630 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3632 * search.c (scan_buffer): Use character positions in calls to
3633 region_cache_forward and region_cache_backward, not byte
3634 positions. (Bug#12196)
3636 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3637 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3639 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3640 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3641 emacs_blocked_malloc, now deleted.
3643 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3645 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3646 The workaround was for improving performance on Solaris 2.4, but
3647 is getting in the way now. Emacs will still work if someone is
3648 still running Solaris 2.4 in a museum somewhere; Sun dropped
3649 support for Solaris 2.4 in 2003.
3650 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3651 * process.c (create_process) [HAVE_WORKING_VFORK]:
3652 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3653 since Emacs no longer uses vfork on that platform.
3655 2012-09-17 Glenn Morris <rgm@gnu.org>
3657 * emacs.c: Use COPYRIGHT.
3659 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3661 Remove configure's --without-sync-input option (Bug#12450).
3662 When auditing signal-handling in preparation for cleaning it up,
3663 I found that SYNC_INPUT has race conditions and would be a real
3664 pain to fix. Since it's an undocumented and deprecated
3665 configure-time option, now seems like a good time to remove it.
3666 Also see <http://bugs.gnu.org/11080#16>.
3667 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3668 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3669 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3670 (malloc_hysteresis):
3671 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3672 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3673 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3674 (dont_register_blocks, bytes_used_when_reconsidered)
3675 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3676 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3677 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3678 Remove. All uses removed.
3679 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3680 implementation, one that depends on whether the new macro
3681 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3683 * atimer.c (run_timers, handle_alarm_signal):
3684 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3685 (handle_async_input, process_pending_signals)
3686 (handle_input_available_signal, init_keyboard):
3687 * nsterm.m (ns_read_socket):
3688 * process.c (wait_reading_process_output):
3689 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3690 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3692 * xterm.c (XTread_socket):
3694 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3695 * eval.c (handling_signal): Remove. All uses removed.
3696 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3697 All uses replaced with the SYNC_INPUT version.
3698 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3700 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3703 * font.c (Ffont_shape_gstring): Remove unused local.
3705 2012-09-16 Glenn Morris <rgm@gnu.org>
3707 * Makefile.in (clean): No longer run nextstep's clean.
3709 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3711 (ns-app): Move here from ns.mk, and simplify.
3712 (clean): Simplify nextstep entry.
3713 * ns.mk: Remove file.
3715 2012-09-17 Kenichi Handa <handa@gnu.org>
3717 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3718 not covert the last few charactes.
3720 2012-09-16 Kenichi Handa <handa@gnu.org>
3722 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3723 here, but just check the validity of glyphs in the glyph-string.
3725 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3727 * window.c (Fwindow_parameter, Fset_window_parameter):
3728 Accept any window as argument (Bug#12452).
3730 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3732 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3733 to ns_term_init to avoid memory leak.
3735 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3736 explicit retain/release.
3737 (ns_term_init): Only allow one display. Initialize outerpool and
3740 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3742 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3743 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3744 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3745 the Microsoft problem in a different way, by altering ../nt/config.nt.
3747 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3762 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3763 by lisp.h. This completes removal of setjmp.h inclusion
3764 erroneously announced in the previous commit. (Bug#12446)
3766 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3769 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3770 not defined as a macro. The latter happens on MS-Windows.
3773 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3775 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3776 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3777 Some instances of '#include <setjmp.h>' removed, if the
3778 only reason for the instance was because "lisp.h" was included.
3779 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3780 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3781 and _longjmp with the new symbols. Emacs already uses _setjmp if
3782 available, so this change affects only POSIXish hosts that have
3783 sigsetjmp but not _setjmp, such as some versions of Solaris and
3784 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3785 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3786 (png_load_body) [HAVE_PNG]:
3787 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3788 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3789 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3790 since PNG requires jmp_buf. This is the only exception to the
3791 general rule that we now use sys_setjmp and sys_longjmp.
3792 This exception is OK since this code does not change the signal
3793 mask or longjmp out of a signal handler.
3795 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3797 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3798 Include "syssignal.h", for 'main_thread'.
3800 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3802 Avoid out-of-range marker position (Bug#12426).
3803 * insdel.c (replace_range, replace_range_2):
3804 Adjust markers before overlays, as suggested by comments.
3805 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3806 Remove redundant check before calling offset_intervals.
3808 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3810 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3811 current buffer (Bug#12387).
3813 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3815 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3817 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3819 Use a more backwards-compatible timer format (Bug#12430).
3820 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3821 vector element, not from the 4th, since PSECS is now at the end.
3822 (Fcurrent_idle_time): Doc fix.
3824 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3826 Function to mark objects and remove killed buffers at once.
3827 * alloc.c (discard_killed_buffers): Rename to ...
3828 (mark_discard_killed buffers) ... new name. Add marking
3829 of remaining objects. Fix comment. Adjust users.
3830 (mark_object): Do not touch frame buffer lists here.
3831 * frame.c (delete_frame): Reset frame buffer lists here.
3833 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3835 Better workaround for GNOME bug when --enable-gcc-warnings.
3836 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3837 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3838 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3840 Simplify SIGIO usage (Bug#12408).
3841 The code that dealt with SIGIO was crufty and confusing, e.g., it
3842 played tricks like "#undef SIGIO" but these tricks were not used
3843 consistently. Simplify mostly by not #undeffing standard symbols,
3844 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3845 or not as we please) rather than "defined SIGIO" (standard symbol
3846 that we probably shouldn't #undef).
3847 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3848 Modules that need it can include it.
3849 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3850 * dispextern.h (ignore_sigio): New decl.
3851 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3852 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3853 * emacs.c (shut_down_emacs):
3854 * keyboard.c (kbd_buffer_store_event_hold):
3855 Use ignore_sigio rather than invoking 'signal' directly.
3856 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3858 (FIONREAD, SIGIO): Do not #undef.
3859 (tty_read_avail_input): Use #error rather than a syntax error.
3860 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3861 for I_PIPE, used by SETUP_SLAVE_PTY.
3862 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3863 * sysdep.c (croak): Remove; no longer needed. This bit of
3864 temporary code, with Fred N. Fish's comment that it's temporary,
3865 has been in Emacs since at least 1992!
3866 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3867 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3868 * syssignal.h (croak): Remove decl.
3869 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3870 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3871 now that we're termios-only.
3872 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3873 * term.c (dissociate_if_controlling_tty): Use #error rather than
3876 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3877 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3878 to work around GNOME bug 683906.
3879 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3880 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3881 This works around GCC bug 54561.
3883 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3885 More fixes for 'volatile' and setjmp/longjmp.
3886 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3887 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3888 (png_load_body) [HAVE_PNG]:
3889 (jpeg_load_body) [HAVE_JPEG]:
3890 New function, with most of the old parent function's body.
3891 (png_load) [HAVE_PNG]:
3892 (jpeg_load) [HAVE_JPEG]:
3893 Invoke the new function, to avoid longjmp munging our locals.
3894 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3895 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3896 longjmp is passed 2, as the C standard doesn't guarantee this.
3897 Instead, store the failure code into mgr->failure_code.
3899 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3901 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3902 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3903 (syms_of_keyboard): Remove support for unread-command-char.
3905 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3907 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3908 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3909 violation. (Bug#12426)
3911 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3913 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3915 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3917 * eval.c: Add `inhibit-debugger'.
3918 (Qinhibit_debugger): New symbol.
3919 (call_debugger): Bind it instead of Qdebug_on_error.
3920 (maybe_call_debugger): Test Vinhibit_debugger.
3921 (syms_of_eval): Define inhibit-debugger.
3922 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3923 (syms_of_xdisp): Remove inhibit-debug-on-message.
3925 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3927 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3928 If a nonvolatile local variable is written before a _longjmp to
3929 the frame containing the variable, and is read after the _longjmp,
3930 the value read is indeterminate. Some local variables of type
3931 'struct handler' and 'struct catchtag' are used in this way, so
3932 mark each of their slots as volatile if the slot can be set before
3933 _longjmp and read afterwards.
3934 * lisp.h (struct handler): var and chosen_clause are now volatile.
3935 (struct catchtag): val, next, and pdlcount are now volatile.
3937 * bidi.c (bidi_push_it, bidi_pop_it):
3938 * fns.c (copy_hash_table):
3939 * image.c (define_image_type):
3940 * keyboard.c (kbd_buffer_store_event_hold):
3941 * process.c (Fprocess_send_eof):
3942 * xfaces.c (x_create_gc) [HAVE_NS]:
3943 * xgselect.c (xg_select):
3944 Prefer assignment to memcpy when either will do.
3946 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3947 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3948 time an item is removed. No need to mark this function 'inline';
3949 the compiler knows better than we do.
3951 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3953 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3954 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3955 to change_frame_size (Bug#12388).
3956 (windowDidResize:): Pass YES to updateFrameSize.
3958 * nsterm.h: Add delay parameter to updateFrameSize.
3960 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3962 Discard killed buffers from deleted window and frame objects.
3963 This reduces an amount of references to killed buffers and
3964 helps GC to reclaim them faster.
3965 * alloc.c (discard_killed_buffers): New function.
3966 (mark_object): Use it for deleted windows and frames.
3967 (mark_object): If symbol's value is set up for a killed buffer
3968 or deleted frame, restore its global binding.
3969 * data.c (swap_in_global_binding): Add GC notice.
3970 (swap_in_symval_forwarding): Use convenient set_blv_where.
3971 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3972 * window.h: ... to here.
3974 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3976 Convenient macro to check whether the buffer is live.
3977 * buffer.h (BUFFER_LIVE_P): New macro.
3978 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3979 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3981 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3983 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3984 composition cases (Bug#12364).
3986 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3987 overhang of succeeding glyphs overlapping box cursor.
3989 * w32term.c (x_draw_glyph_string): Likewise.
3991 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3993 Simplify, document, and port floating-point (Bug#12381).
3994 The porting part of this patch fixes bugs on non-IEEE platforms
3995 with frexp, ldexp, logb.
3996 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3998 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3999 support, by removing commented-out code and briefly listing the
4000 C89 functions excluded. The commented-out stuff was confusing
4001 maintenance, e.g., we thought we needed cbrt but it was commented out.
4002 (logb): Remove decl; no longer needed.
4003 (isfinite): New macro, if not already supplied.
4004 (isnan): Don't replace any existing macro.
4005 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4006 are present on all C89 platforms.
4007 (Ffrexp): Do not special-case zero, as frexp does the right thing
4009 (Flogb): Do not use logb, as it doesn't have the desired meaning
4010 on hosts that use non-base-2 floating point. Instead, stick with
4011 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4012 frexp, to avoid getting an unspecified result.
4014 * xdisp.c (Qinhibit_debug_on_message): Now static.
4016 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4018 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4019 NSBezierPath (Bug#12131).
4021 2012-09-10 Chong Yidong <cyd@gnu.org>
4023 * fns.c (Fdelq, Fdelete): Doc fix.
4025 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4027 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4028 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4030 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4032 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4033 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4036 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4038 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4039 left fringe if the window has a left margin. This avoids leaving
4040 traces of the cursor because its leftmost pixel is not drawn over.
4042 * dispnew.c (update_window_line): When the left margin area of a
4043 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4044 that screen line. (Bug#12277)
4046 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4048 Assume C89 or later for math functions (Bug#12381).
4049 This simplifies the code, and makes it a bit smaller and faster,
4050 and (most important) makes it easier to clean up signal handling
4051 since we can stop worring about floating-point exceptions in
4052 library code. That was a problem before C89, but the problem
4053 went away many years ago on all practical Emacs targets.
4054 * data.c, image.c, lread.c, print.c:
4055 Don't include <math.h>; no longer needed.
4056 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4057 might be autoconfigured, as that never happens.
4059 * doprnt.c (DBL_MAX_10_EXP):
4060 * print.c (DBL_DIG):
4061 Remove. C89 or later always defines these.
4062 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4063 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4064 (arith_error, domain_error, domain_error2):
4065 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4066 no longer needed -- we simply return what C returns. All uses removed.
4067 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4069 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4070 Remove. All uses expanded, as these macros are no longer used
4071 more than once and are now more trouble than they're worth.
4072 (Ftan): Use tan, not sin / cos.
4073 (Flogb): Assume C89 frexp.
4074 (fmod_float): Assume C89 fmod.
4075 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4076 (init_floatfns): Remove. All uses removed.
4078 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4080 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4081 compositeToPoint for OSX < 10.6 (Bug#12390).
4083 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4085 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4086 This produces more-accurate results.
4088 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4090 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4091 changes (Bug#12088).
4093 2012-09-08 Chong Yidong <cyd@gnu.org>
4095 * syntax.c (Fstring_to_syntax): Doc fix.
4097 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4099 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4100 in the internal border.
4101 (x_set_window_size): Remove static variables and their usage.
4102 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4103 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4104 Remove fringe/internal border adjustment (Bug#11052).
4105 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4106 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4107 (ns_fix_rect_ibw): Remove.
4108 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4109 (ns_dumpglyphs_box_or_relief): Ditto.
4110 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4112 (ns_dumpglyphs_image): Ditto.
4113 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4115 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4116 their usage. Add fringe_extended_p and its use as in other terms.
4117 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4118 scroll bar was removed.
4119 (updateFrameSize): New function.
4120 (windowDidResize): Move code to updateFrameSize and call it.
4122 * nsterm.h (EmacsView): Add updateFrameSize.
4124 2012-09-07 Chong Yidong <cyd@gnu.org>
4126 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4128 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4130 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4132 More signal-handler cleanup (Bug#12327).
4133 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4134 Problem introduced when merging patches. Noted by Eli Zaretskii in
4135 <http://bugs.gnu.org/12327#67>.
4136 * floatfns.c: Comment fix.
4137 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4138 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4139 and anyway the declaration is harmless even if SIGDANGER is not defined.
4140 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4141 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4142 source files not surprisingly expected syssignal.h to define, or
4143 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4144 Include <sys/ioctl.h>, for FIONREAD.
4145 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4146 This eliminates a problem whereby other files mysteriously had
4147 to include "syssignal.h" before including "systty.h" if they
4148 wanted to use "#ifdef SIGIO".
4150 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4152 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4154 * w32.c (sigemptyset): Empty the set.
4155 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4157 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4159 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4161 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4162 (mark_object): Likewise for frame objects.
4164 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4166 * syssignal.h (handle_on_main_thread): Always declare,
4167 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4168 This ports to platforms without HAVE_PTHREAD.
4170 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4172 Signal-handler cleanup (Bug#12327).
4173 Emacs's signal handlers were written in the old 4.2BSD style with
4174 sigblock and sigmask and so forth, and this led to some
4175 inefficiencies and confusion. Rewrite these to use
4176 pthread_sigmask etc. without copying signal sets around. Also,
4177 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4178 'signal', and instead use functions that do not attempt to take
4179 over the system name space. This patch causes Emacs's text
4180 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4181 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4182 Do not include <signal.h> or "syssignal.h", as these
4183 modules do not use signals.
4184 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4185 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4186 Do not include <signal.h>, as "syssignal.h" does that for us now.
4187 * atimer.c (sigmask_atimers): New function.
4188 (block_atimers, unblock_atimers): New functions,
4189 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4191 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4192 no longer needed here.
4193 * emacs.c (main): Inspect existing signal handler with sigaction,
4194 so that there's no need to block and unblock SIGHUP.
4195 * sysdep.c (struct save_signal): New member 'action', replacing
4196 old member 'handler'.
4197 (save_signal_handlers, restore_signal_handlers):
4198 Use sigaction instead of 'signal' to save and restore.
4199 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4200 New function. All users of 'signal' modified to use set_sighandler
4201 if they're writeonly, and to use sys_signal if they're read+write.
4202 (emacs_sigaction_init, forwarded_signal): New functions.
4203 (sys_signal): Remove. All uses replaced by calls to sigaction
4204 and emacs_sigaction_init, or by direct calls to 'signal'.
4205 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4206 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4207 all uses replaced by pthread_sigmask etc. calls.
4208 * syssignal.h: Include <signal.h>.
4209 (emacs_sigaction_init, forwarded_signal): New decls.
4210 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4211 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4212 (sigmask, sys_sigmask): Remove; no longer needed.
4213 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4214 (sigblock, sigunblock, sigfree):
4215 (sigsetmask) [!defined sigsetmask]:
4216 Remove. All uses replaced by pthread_sigmask.
4217 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4218 no longer need to be replaced, and its typical old uses
4219 are now done via emacs_sigaction_init and sigaction.
4220 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4221 (sys_sigdel): Remove; unused.
4222 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4224 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4226 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4227 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4229 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4231 Explicitly mark buffer_defaults and buffer_local_symbols.
4232 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4233 mark_local_symbols here.
4234 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4235 since special buffers aren't marked here any more.
4236 (allocate_buffer): Chain new buffer with all_buffers here...
4237 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4239 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4240 (syms_of_buffer): Remove staticpro of the above.
4241 (init_buffer_once): Set names for buffer_defaults and
4242 buffer_local_symbols.
4244 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4246 Use bool for booleans in font-related modules.
4247 * font.c (font_intern_prop, font_style_to_value)
4248 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4249 (generate_otf_features, font_check_otf_features, font_check_otf)
4250 (font_match_p, font_list_entities, font_at):
4251 * fontset.c (fontset_id_valid_p, reorder_font_vector
4252 (fontset_find_font, Fset_fontset_font)
4253 (face_suitable_for_char_p) [0]:
4254 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4255 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4256 (m17n_flt_initialized, ftfont_shape_by_flt):
4257 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4258 * nsfont.m (nsfont_draw):
4259 * w32font.c (w32font_draw):
4260 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4261 Use bool for booleans.
4262 * font.h: Adjust to above API changes.
4263 (struct font, struct font_driver, struct font_driver_list):
4264 Use bool for booleans.
4265 (struct font): Remove useless member encoding_type.
4267 * fontset.c, xftfont.c: Omit unnecessary static decls.
4269 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4271 * alloc.c (mark_object): Revert window marking code
4272 since it's unsafe for the Fset_window_configuration.
4274 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4276 Fix race conditions with signal handlers and errno (Bug#12327).
4277 Be more systematic about preserving errno whenever a signal
4278 handler returns, even if it's not in the main thread. Do this by
4279 renaming signal handlers to distinguish between signal delivery
4280 and signal handling. All uses changed.
4281 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4282 * data.c (deliver_arith_signal): Rename from arith_error.
4283 * dispnew.c (deliver_window_change_signal): Rename from
4284 window_change_signal.
4285 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4286 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4287 * keyboard.c (deliver_input_available_signal): Rename from
4288 input_available_signal.
4289 (deliver_user_signal): Rename from handle_user_signal.
4290 (deliver_interrupt_signal): Rename from interrupt_signal.
4291 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4292 (deliver_child_signal): Rename from sigchld_handler.
4293 * atimer.c (handle_alarm_signal):
4294 * data.c (handle_arith_signal):
4295 * dispnew.c (handle_window_change_signal):
4296 * emacs.c (handle_fatal_signal, handle_danger_signal):
4297 * keyboard.c (handle_input_available_signal):
4298 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4299 * process.c (handle_pipe_signal, handle_child_signal):
4300 New functions, with the actual signal-handling code taken from the
4301 original respective signal handlers, sans the sporadic attempts to
4302 preserve errno, since that's now done by handle_on_main_thread.
4303 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4304 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4305 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4307 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4308 Move initialization of main_thread to sysdep.c's init_signals.
4309 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4310 our usage, and simplifies the mainline code.
4311 (record_child_status_change): New static function, as a helper
4312 for handle_child_signal, and with most of the old child handler's
4314 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4315 (handle_child_signal): Use the above.
4316 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4317 Moved here from emacs.c.
4318 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4319 code moved here from emacs.c's main function.
4320 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4321 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4322 This lets callers save and restore errno properly.
4324 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4326 Remove redundant or unused things here and there.
4327 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4328 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4329 * editfns.c (Fcompare_buffer_substrings): Likewise.
4330 * frame.h (struct terminal, struct font_driver_list):
4331 Remove redundant declarations.
4332 * window.h (Qleft, Qright): Likewise.
4334 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4336 Do not mark objects from deleted buffers, windows and frames.
4337 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4338 (mark_object): Likewise for windows and frames.
4340 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4342 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4343 buffer_defaults and buffer_local_symbols as valid objects.
4344 Return special value to denote them.
4346 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4348 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4349 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4350 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4351 (file_name_absolute_p, Fsubstitute_in_file_name):
4352 (check_executable, check_writable, Ffile_accessible_directory_p)
4353 (Fset_file_selinux_context, Fdefault_file_modes)
4354 (Finsert_file_contents, choose_write_coding_system)
4355 (Fwrite_region, build_annotations, a_write, e_write)
4357 * filelock.c (boot_time_initialized, get_boot_time)
4358 (get_boot_time_1, lock_file_1, within_one_second):
4359 * floatfns.c (in_float):
4360 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4361 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4362 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4363 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4364 * window.c (compare_window_configurations):
4365 Use bool for booleans.
4366 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4367 (Fdefault_file_modes): Now mode_t, not int, for modes.
4368 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4369 (internal_delete_file): Now returns void, not a (boolean) int,
4370 since nobody was looking at the return value.
4371 * lisp.h, window.h: Adjust to above API changes.
4373 * xdisp.c (set_message): Simplify and reindent last change.
4375 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4377 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4379 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4381 * eval.c (call_debugger): Make the function non-static so that we
4382 can call it from set_message.
4384 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4385 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4387 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4389 Give more-useful info on a fatal error (Bug#12328).
4390 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4391 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4392 of doing the work ourselves.
4393 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4394 do most of the work.
4395 (fatal_error_backtrace): New function, taken from the guts
4396 of the old fatal_error_signal, but with a new option to output
4398 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4399 info about the signal than just its number.
4400 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4401 * sysdep.c: Include <execinfo.h>
4402 (emacs_backtrace): New function, taken partly from the previous
4403 code of the 'die' function.
4404 (emacs_abort): Call fatal_error_backtrace rather than abort.
4406 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4408 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4409 eager (load-time) macro-expansion.
4410 * lisp.mk (lisp): Add macroexp.
4412 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4414 Simplify redefinition of 'abort' (Bug#12316).
4415 Do not try to redefine the 'abort' function. Instead, redo
4416 the code so that it calls 'emacs_abort' rather than 'abort'.
4417 This removes the need for the NO_ABORT configure-time macro
4418 and makes it easier to change the abort code to do a backtrace.
4419 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4420 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4421 Remove; sysdep.c's emacs_abort now takes its place.
4422 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4423 'abort' changed to use 'emacs_abort'.
4424 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4425 (abort) [!defined abort]: Rename to ...
4426 (emacs_abort): ... new name.
4427 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4428 the place of the old 'abort' in emacs.c.
4429 * w32.c, w32fns.c (abort): Do not #undef.
4430 * w32.c (emacs_abort): Rename from w32_abort.
4432 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4434 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4435 offsets[j].dv, since the y axis of the screen coordinates points
4436 down, while the y axis of the font definition coordinates points
4437 up. This fixes display of Arabic diacritics such as KASRA and
4438 KASRATAN. (Bug#11860)
4440 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4442 Be more systematic about _setjmp vs setjmp.
4443 * alloc.c (test_setjmp, mark_stack):
4444 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4445 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4446 (png_load, my_error_exit, jpeg_load):
4447 * process.c (send_process_trap, send_process):
4448 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4449 The underscored versions are up to 30x faster on some hosts.
4450 Formerly, the code used setjmp+longjmp sometimes and
4451 _setjmp+_longjmp at other times, with no particular reason to
4452 prefer setjmp+longjmp.
4454 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4456 Fix minor problem found by static checking.
4457 * buffer.c (Fdelete_all_overlays): Return nil.
4459 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4461 * buffer.c (Fdelete_all_overlays): New function.
4463 2012-09-03 Chong Yidong <cyd@gnu.org>
4465 * gtkutil.c: Add extern decl for Qxft.
4467 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4469 * emacs.c, eval.c: Use bool for boolean.
4470 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4471 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4472 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4473 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4474 (main, decode_env_path, Fdaemon_initialized):
4475 * eval.c (call_debugger, Finteractive_p, interactive_p):
4476 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4477 (maybe_call_debugger, Fbacktrace):
4478 * process.c (read_process_output, exec_sentinel):
4479 Use bool for booleans.
4480 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4481 All callers changed.
4482 * eval.c (interactive_p): Omit always-true boolean argument
4483 EXCLUDE_SUBRS_P. All callers changed.
4484 * dispextern.h, lisp.h: Reflect above API changes.
4485 * firstfile.c (dummy): Use the address of 'main', whose signature
4486 won't change, instead of the address of 'initialize', whose
4487 signature just changed from int to bool.
4488 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4489 * msdos.c (fatal_error_in_progress): ... from here.
4490 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4492 (redisplay_internal, unwind_redisplay): Simply clear
4493 REDISPLAYING_P when unwinding, instead of saving its previous,
4494 always-false value and then restoring it.
4496 Clean up some extern decls.
4497 Mostly, this hoists extern decls out of .c files and into .h files.
4498 That way, we're more likely to catch errors if the interfaces change.
4499 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4500 declare xg_mark_data.
4501 * dispextern.h (x_frame_parm_handlers):
4503 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4504 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4505 (Qultra_bold, Qoblique, Qitalic):
4506 Move extern decl here from .c file.
4507 * alloc.c (xg_mark_data) [USE_GTK]:
4509 * eval.c (Qlexical_binding):
4510 * fns.c (time) [!HAVE_UNISTD_H]:
4511 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
4512 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

4514 * lread.c (Qinternal_interpreter_environment):
4515 * minibuf.c (Qbuffer):
4516 * process.c (QCfamily, QCfilter):
4517 * widget.c (free_frame_faces):
4518 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4519 * xfont.c (x_clear_errors):
4520 * xterm.c (x_frame_parm_handlers):
4521 Remove now-redundant extern decls.
4522 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4523 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4525 * xfaces.c: Remove unnecessary static decls.
4526 * xterm.c (updating_frame): Remove decl of nonexistent object.
4528 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4529 when building globals.h, as the objects that are not built on
4530 this host are not needed to compile C files on this host.
4532 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4534 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4536 * frame.h: Add missing prototype for x_wm_set_size_hint.
4538 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4540 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.
4541 * doc.c (read_bytecode_char, get_doc_string, reread_doc_file)
4542 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4543 (Fsubstitute_command_keys):

4548 (make_buffer_string, make_buffer_string_both)
4549 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
4550 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)
4551 (copy_text, insert_1, insert_1_both, insert_from_string)

4586 offset adjustment values separately for each cluster. (Bug#11860)
4588 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4589 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4590 about implicit conversions from integer to pointer.

4648 window system declarations.
4650 * frame.h: Move common functions here: set_frame_menubar,
4651 x_set_window_size, x_sync, x_get_focus_frame,
4652 x_set_mouse_position, x_set_mouse_pixel_position,
4653 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4709 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4710 for GCC 4.7.1 x86-64.
4712 2012-08-30 Glenn Morris <rgm@gnu.org>
4714 * lread.c (init_lread): For out-of-tree builds, only add the
4715 source directory's site-lisp dir to the load-path if it exists,
4716 consistent with in-tree builds. (Bug#12302)
4718 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

4952 It was meant to be temporary and it often doesn't work,
4953 because when IDX has side effects the behavior of IDX==IDX
4954 is undefined. See Stefan Monnier in
4955 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

4971 All uses and decls removed.

5001 Use bool for booleans, instead of int.
5002 * lisp.h, process.h: Adjust prototypes to match above changes.
5003 * callint.c (Fcall_interactively): Don't assume the mark's
5004 offset fits in 'int'.
5006 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5008 * buffer.c, buffer.h: Use bool for boolean.
5009 * buffer.c (reset_buffer_local_variables)
5010 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5011 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5012 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5013 (overlay_touches_p, overlay_strings, Foverlay_put)
5014 (report_overlay_modification, call_overlay_mod_hooks):
5015 (mmap_enlarge, mmap_set_vars):
5016 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5017 Use bool for booleans, instead of int.
5018 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5019 since the 1-or-0 return value is always ignored anyway.
5020 (mmap_initialized_p):
5021 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5022 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5024 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5026 * bidi.c: Use bool for boolean.
5027 This is a bit more readable, and makes the text segment of bidi.o
5028 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5029 Presumably it's faster too.
5030 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5032 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5033 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5034 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5035 (bidi_explicit_dir_char, bidi_level_of_next_char)
5036 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5037 Use bool for booleans, instead of int.
5038 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5039 (bidi_unshelve_cache): Adjust decls to match code.
5041 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5043 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5046 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5048 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5049 * atimer.h: Include <stdbool.h>.
5051 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5053 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5054 compile time tests instead of run time tests on systems that do
5056 (FRAME_MAC_P): Remove leftover from deleted code.
5057 * frame.c (syms_of_frame): Remove leftover from deleted code.
5059 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5061 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5063 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5065 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5066 Otherwise, the compiler complains about (A?B:C) where B is void
5067 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5068 (fontset_add): Return void, for FONTSET_ADD.
5070 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5072 * alloc.c: Use bool for booleans.
5073 (gc_in_progress, abort_on_gc)
5074 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5075 (dont_register_blocks) [GC_MALLOC_CHECK]:
5076 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5077 (check_string_bytes, make_specified_string, memory_full)
5078 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5079 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5080 (mark_stack, valid_pointer_p, make_pure_string)
5081 (Fgarbage_collect, survives_gc_p, gc_sweep):
5082 Use bool for booleans, instead of int.
5083 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5084 Remove unused local.
5085 * alloc.c (PURE_POINTER_P):
5086 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5087 * editfns.c (Fformat):
5088 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5090 * fns.c (sweep_weak_table):
5091 * lisp.h (suppress_checking, push_message, survives_gc_p)
5092 (make_pure_string, gc_in_progress, abort_on_gc):
5093 * lread.c (readchar, read1):
5094 * print.c (Fprin1_to_string):
5095 * xdisp.c (push_message):
5096 Use bool for booleans affected directly or indirectly by
5099 Make recently-introduced setters macros.
5100 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5101 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5102 (set_fontset_default, set_fontset_fallback): Rename from their
5103 upper-case counterparts, and make them functions rather than macros.
5104 This is more consistent with the other recently-introduced setters.
5105 These don't need to be inline, since they're local.
5107 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5109 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5110 the loop (Bug#12247).
5112 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5114 * lisp.h (vcopy): Use memcpy rather than our own loop.
5115 This fixes a performance regression introduced by the recent
5116 addition of vcopy. This means 'vcopy' will need to be modified
5117 for a copying collector, but that's OK. Also, tighten the
5118 checking in the assertion.
5120 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5122 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5123 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5124 non-base glyph for the width of the base character, according to
5125 what x_draw_composite_glyph_string_foreground expects.
5126 Generate WADJUST value according to composition_gstring_width's
5127 expectations, to produce correct width of the composed character.
5128 Reverse the sign of the DU offset produced by ScriptPlace.
5130 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5132 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5134 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5136 Avoid direct writes to contents member of struct Lisp_Vector.
5137 * lisp.h (vcopy): New function to copy data into vector.
5138 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5139 * fns.c (Ffillarray): Use ASET.
5140 * keyboard.c (timer_check_2): Use AREF and ASET.
5141 (append_tool_bar_item, Frecent_keys): Use vcopy.
5142 * lread.c (read_vector): Use ASET.
5143 * msdos.c (Frecent_doskeys): Use vcopy.
5144 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5145 (Finternal_merge_in_global_face): Use ASET and vcopy.
5146 * xfont.c (xfont_list_pattern): Likewise.
5148 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5150 * window.c (Fwindow_point): For the selected window always return
5151 the position of its buffer's point.
5152 (Fset_window_point): For the selected window always go in its
5153 buffer to the specified position.
5155 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5157 Setter macros for fontsets.
5158 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5159 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5160 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5163 2012-08-20 Glenn Morris <rgm@gnu.org>
5165 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5166 Don't assume that `ln -f' works.
5168 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5170 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5171 and later about non-assignments with no effect. See discussion at
5172 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5175 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5177 Inline setter functions for Lisp_Objects slots of struct specbinding.
5178 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5181 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5183 * window.c (select_window): Always make selected window's buffer
5186 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5188 Use AREF and ASET for docstrings of category tables.
5189 * category.h (CATEGORY_DOCSTRING): Use AREF.
5190 (SET_CATEGORY_DOCSTRING): Use ASET.
5191 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5193 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5195 Inline setter functions for hash table members.
5196 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5197 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5198 (set_hash_key_and_value, set_hash_index, set_hash_next)
5199 (set_hash_hash): New functions.
5200 * charset.c, fns.c: Adjust users.
5202 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5204 Inline getter and setter functions for per-buffer values.
5205 * buffer.h (per_buffer_default, set_per_buffer_default)
5206 (per_buffer_value, set_per_buffer_value): New functions.
5207 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5208 * buffer.c, data.c: Adjust users.
5210 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5212 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5214 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5216 Rely on <config.h> + <unistd.h> to declare 'environ',
5217 as gnulib does this if the system doesn't.
5218 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5219 Remove declaration. MS-Windows declares it on stdlib.h which is
5220 included by conf_post.h.
5221 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5222 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5223 * vm-limit.c: Include <unistd.h>, for 'environ'.
5225 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5226 (start_of_data): Remove decl; mem-limits.h provides it.
5228 * xdisp.c (handle_invisible_prop): Make it a bit faster
5229 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5231 2012-08-19 Chong Yidong <cyd@gnu.org>
5233 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5236 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5238 * .gdbinit: Use call instead of set when calling a function in the
5241 * data.c (set_internal): Don't use set_blv_found.
5242 (Fkill_local_variable): Likewise.
5244 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5246 * nsfont.m (ns_ascii_average_width): Ensure the string
5247 ascii_printable is initialized with a null-terminated character
5248 array. Otherwise, it can contain undesired extra characters.
5250 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5252 port new setting code to Sun C 5.8 2005/10/13
5253 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5254 Return void, not Lisp_Object. Otherwise, the compiler
5255 complains about (A?B:C) where B is void and C is Lisp_Object
5256 when compiling CHAR_TABLE_SET, due to the recent change to
5257 the API of sub_char_table_set_contents.
5259 2012-08-18 Chong Yidong <cyd@gnu.org>
5261 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5262 for the string case (Bug#3874).
5264 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5266 * buffer.h (BSET): Remove (Bug#12215).

5312 (pset_type, pset_write_queue): New setter functions.
5314 * window.h (WSET): Remove (Bug#12215).
5315 Replace all uses with calls to new setter functions.
5316 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
5317 (WINDOW_INLINE): New macro.

5336 New setter functions.
5338 * termhooks.h (TSET): Remove (Bug#12215).

5345 are compiled into code.
5346 (tset_param_alist): New setter function.
5348 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
5350 * keyboard.h (KSET): Remove (Bug#12215).

5383 A few more naming-convention fixes for getters and setters.
5384 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,
5385 and rename from buffer_overlays_set_before.
5386 (set_buffer_overlays_after): Move here from buffer.h, and rename
5387 from buffer_overlays_set_after.
5388 * buffer.h (buffer_intervals): Rename from buffer_get_intervals.

5395 (set_interval_right): Move here from intervals.h, and rename from
5397 (copy_interval_parent): Move here from intervals.h, and rename from
5398 interval_copy_parent.
5399 * intervals.h (set_interval_parent): Rename from interval_set_parent.
5400 (set_interval_plist): Rename from interval_set_plist.
5401 Return void, not Lisp_Object, since no caller uses the result.
5402 * lisp.h (string_intervals): Rename from string_get_intervals.

5415 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
5416 "set_char_table_parent (char_table, parent);".
5417 The old version was confusing because it used the same name
5418 'parent' for two different things.
5420 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
5422 Functions to get and set Lisp_Object fields of buffer-local variables.

6089 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6090 * w32.c (init_environment): Change the default values of many
6091 environment variables in dflt_envvars[] to NULL, to avoid pushing
6092 them into environment when they were not already defined.
6093 Remove the code that deletes site-lisp subdirectories from the default
6094 value of EMACSLOADPATH, as it is no longer needed.
6095 (check_windows_init_file): Now external, not static.
6096 Use Vload_path as is, without adding anything, as this function is now
6097 called when Vload_path is already set up.
6099 * w32.h (check_windows_init_file): Add prototype.
6101 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6129 Remove unnecessary casts involving pointers.
6130 These casts are no longer needed now that we assume C89 or later,

6144 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6145 Remove unnecessary pointer casts.
6146 * alloc.c (record_xmalloc): New function.
6147 * lisp.h (record_xmalloc): New decl.
6148 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6149 more like a function. This is because the pointer cast is not
6150 needed. All uses changed.
6151 * print.c (print_string, print_error_message): Avoid length recalc.
6153 Improve fix for macroexp crash with debugging (Bug#12118).
6154 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6155 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6156 not supposed to be invoked from the garbage collector.

6158 (gc_aset): New function, which is like ASET but can be
6159 used in the garbage collector.

6188 with addition of handling of symlinks and support for 'lstat'.
6189 If possible, get file's attributes and security information by
6190 handle, not by name. Produce S_IFLNK bit for symlinks, when
6191 called from 'lstat'.
6192 (stat, lstat): New functions, call 'stat_worker'.
6193 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6194 symlinks when the underlying filesystem supports them.
6196 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6198 Fix macroexp crash on Windows with debugging (Bug#12118).
6199 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6200 checking subscripts; problem introduced with the recent
6201 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6202 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6203 since it's used in non-static inline functions now.
6205 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6206 Don't assume buffer size fits in 'int'. Remove unused local.

6226 * composite.c (COMPOSITE_INLINE):
6227 * dispnew.c (DISPEXTERN_INLINE):
6228 * sysdep.c (SYSTIME_INLINE):
6229 Define to EXTERN_INLINE, so that the corresponding functions
6230 are compiled into code.
6231 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6232 (INLINE_HEADER_END): New macros.
6233 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6253 hard-coding the path separator.
6255 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6257 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6258 This how ASET and AREF are supposed to work, and makes
6259 it easier to think about future improvements. See
6260 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6261 * charset.h (set_charset_attr): New function.

6766 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6767 not be usable in #if. This simplifies things.

6776 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6777 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6778 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6779 Adjust to changes in lisp.h and emacs.c, by using
6780 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6781 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6782 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6783 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6784 instead of gdb_valbits.
6785 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6786 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6787 instead of gdb_array_mark_flag.
6788 (xboolvector): Get size from $->size, not $->header.size.
6789 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6790 (xreload, hook-run, hookpost-run): Remove.
6791 * emacs.c: Include <verify.h>.
6792 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

6797 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6798 Also define these as enum constants, so they're visible to GDB.
6799 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6800 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6801 as constants, so they're visible to GDB.

6803 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6804 Now enum constants, not macros, so they're visible to GDB.
6805 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6806 more convenient now. All uses changed.
6807 (VALMASK) [USE_LSB_TAG]: Also define in this case.

6820 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6822 Use typedef for EMACS_INT, EMACS_UINT.
6823 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6824 than macros. This simplifies debugging in the usual case, since
6825 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6826 and it allows expressions involving EMACS_INT casts.
6827 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6829 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6845 (init_buffer_once): Initialize indirection counters of
6846 buffer_defaults and buffer_local_symbols (for sanity and safety).
6848 2012-07-24 Eli Zaretskii <eliz@gnu.org>

6881 Swap buffer text indirection counters in Fbuffer_swap_text.
6882 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6883 This avoids crash reported by Christoph Scholtes at
6884 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6886 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6888 * nsmenu.m (Popdown_data): New struct.

6911 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6913 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6914 as it's limited by the amount of memory, not by INT_MAX.
6916 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6918 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

7075 * keyboard.c (command_loop_1): Set it.
7076 * cmds.c (Fself_insert_command): Use it to only remove boundaries that

7664 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
7665 (add_emacs_time, sub_emacs_time): New functions.
7666 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

7692 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7693 * nsterm.m (ns_term_init):
7694 Avoid the need for strncpy, by using build_string or
7695 make_unibyte_string directly. Use dtoastr, not snprintf.
7696 * process.c (Fmake_network_process): Diagnose service names that
7697 are too long, rather than silently truncating them or creating
7698 non-null-terminated names.
7699 (Fnetwork_interface_info): Likewise, for interface names.
7700 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7701 Prefer sprintf to strncat.
7702 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

7708 Clarify fallback case.
7710 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

7713 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
7714 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7715 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

7728 Optimize pure C strings initialization.
7729 * lisp.h (make_pure_string): Fix prototype.
7730 (build_pure_c_string): New function, defined as static inline. This
7731 provides a better opportunity to optimize away calls to strlen when
7732 the function is called with compile-time constant argument.
7733 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7734 argument, adjust users accordingly. Use build_pure_c_string where
7736 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7737 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7738 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7740 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7742 Avoid calls to strlen in miscellaneous functions.
7743 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7744 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7745 * lread.c (openp): Likewise.

7749 Avoid calls to strlen in path processing functions.
7750 * fileio.c (file_name_as_directory): Add comment. Change to add
7751 srclen argument and return the length of result. Adjust users

7755 Adjust users accordingly.
7756 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7758 2012-07-10 Glenn Morris <rgm@gnu.org>

7765 * s/gnu.h (DATA_START): Move definitions to configure.
7767 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7768 We include usg5-4-common.h, which defines them both.
7770 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7771 O_RDONLY already includes it).
7773 Stop ns builds setting the EMACSLOADPATH environment variable.
7774 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7775 Now it does not set EMACSLOADPATH, just returns the load-path string.
7776 * nsterm.h: Update accordingly.
7777 * lread.c [HAVE_NS]: Include nsterm.h.
7778 (init_lread) [HAVE_NS]: Use ns_load_path.

7781 2012-07-09 Glenn Morris <rgm@gnu.org>
7783 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7784 since the included bsd-common.h does so.
7786 Stop ns builds setting the EMACSPATH environment variable.
7787 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7788 (ns_init_paths): Do not set EMACSPATH.
7789 * nsterm.h (ns_exec_path): Add it.
7790 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7793 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7795 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7797 * process.c (wait_reading_process_output): 'waitchannels' was unset
7798 when read_kbd || !NILP (wait_for_cell); fix this.
7800 Add GCC-style 'const' attribute to functions that can use it.
7801 * character.h (char_resolve_modifier_mask):
7802 * keyboard.h (make_ctrl_char):
7803 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7812 Add decls with ATTRIBUTE_CONST.
7814 Minor improvements to make_formatted_string.
7815 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7816 where int is good enough, as vsprintf returns an int.
7817 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7819 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7821 Use make_formatted_string to avoid double length calculation.
7822 * lisp.h (make_formatted_string): New prototype.
7823 * alloc.c (make_formatted_string): New function.
7824 * buffer.c (Fgenerate_new_buffer_name): Use it.

7846 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7848 Move marker debugging code under MARKER_DEBUG.
7849 * marker.c (MARKER_DEBUG): Move marker debugging code under
7850 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7851 for bootstrap with --enable-checking (~3x slowdown reported
7852 by Juanma Barranquero <lekktu@gmail.com>).
7853 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7855 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7857 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7858 See <http://bugs.gnu.org/11825#29>.
7860 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7862 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7863 has no font, use the frame's font. (Bug#11813)
7864 (display_line): Add commentary about displaying truncation glyphs
7866 (produce_special_glyphs): Move here from term.c.
7868 * term.c (produce_special_glyphs): Move to xdisp.c.
7870 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7873 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7875 * xdisp.c (display_line): Avoid warning about implicit declaration
7878 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7880 * lisp.h: Remove empty conditional.
7882 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7884 * lread.c (load_path_check): Now static.
7886 Fix some minor --with-ns problems found by static checking.
7887 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7888 (x_set_font) [!HAVE_X_WINDOWS]:
7889 * image.c (xpm_load_image) [HAVE_NS]:
7890 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7891 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7892 Remove unused local.
7893 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7894 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7895 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7896 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7897 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7898 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7899 Fix pointer signedness problem.
7900 * xfaces.c (FRAME_X_FONT_TABLE):
7901 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7903 2012-07-07 Glenn Morris <rgm@gnu.org>
7905 * lread.c (load_path_check): New function, split from init_lread.
7906 (init_lread): Reorganize. Motivation:
7907 If EMACSLOADPATH is set, check/warn about that rather than the
7908 defaults, which we are not going to use. Hence we can remove
7909 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7910 Don't warn if site-lisp directories are missing.
7911 If not installed, start from a blank load-path, since
7912 PATH_LOADSEARCH refers to the eventual installation directories.
7914 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7916 Support truncation and continuation glyphs on GUI frames, when
7917 fringes are disabled. (Bug#11832)
7918 * xdisp.c (init_iterator): Get dimensions of truncation and
7919 continuation glyphs even if on GUI frames.
7920 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7921 or both, are absent.
7922 (start_display, move_it_in_display_line_to): Handle the case of a
7923 GUI frame without a fringe to display continuation or truncation
7925 (insert_left_trunc_glyphs): Support GUI frames: make sure
7926 truncation glyphs overwrite enough glyphs from the current line to
7927 have sufficient space in pixels.
7928 (display_line): Support truncation and continuation glyphs on GUI
7929 frames. If some spare pixels are left on the line after inserting
7930 the truncation glyphs, fill that space with a stretch glyph of a
7931 suitably computed width.
7933 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7934 produce_glyphs, to support GUI sessions.
7936 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7938 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7940 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7942 Do not require float-time's arg to fit in time_t (Bug#11825).
7943 This works better on hosts where time_t is unsigned, and where
7944 float-time is applied to the (negative) difference between two times.
7945 * editfns.c (decode_time_components): Last arg is now double *,
7946 not int *, and means to store all the result as a double, without
7947 worrying about whether the seconds part fits in time_t.
7948 All callers changed.
7949 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7950 All callers changed.
7951 (Ffloat_time): Do not fail merely because the specified time falls
7952 outside of time_t range.
7954 2012-07-07 Glenn Morris <rgm@gnu.org>
7956 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
7957 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
7958 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
7960 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
7962 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7963 Update dependencies.
7965 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7967 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7969 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

7971 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7972 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7973 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7974 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7976 * xfont.c (compare_font_names): Redo to omit the need for casts.
7978 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7980 * xfns.c (Fx_change_window_property): Doc fix.
7981 * w32fns.c (Fx_change_window_property): Doc fix.
7983 * w32fns.c (Fx_window_property): Accept the same arguments as the
7984 X Windows version. Doc fix.
7985 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7987 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7988 Eli Zaretskii <eliz@gnu.org>
7990 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7991 Windows-specific code from nt/config.nt moved here.
7992 Obsolete settings removed.
7994 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7996 * process.c: Avoid unnecessary calls to gettime.
7997 (wait_reading_process_output): Don't get the time of day
7998 when gobbling data immediately and not waiting, as there's no need
7999 for it in that case. This removes a FIXME.
8001 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8003 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8004 is defined (Bug#11768).
8006 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8008 Fix marker debugging code.
8009 * marker.c (byte_char_debug_check): Do not perform the check
8010 if buffer is not multibyte.
8011 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8012 Call byte_char_debug_check with correct arguments.
8014 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8016 Compile marker debugging code only if ENABLE_CHECKING is defined.
8017 * marker.c (byte_char_debug_check, count_markers):
8018 Use only if ENABLE_CHECKING is defined.
8019 (byte_debug_flag): Remove.
8020 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8021 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8023 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8025 Avoid code repetition in marker-related functions.
8026 * marker.c (attach_marker): New function.
8027 (Fset_marker, set_marker_restricted, set_marker_both)
8028 (set_marker_restricted_both): Use it.
8029 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8030 Consistently rename charno to charpos.
8031 (marker_position): Add eassert.
8032 (marker_byte_position): Convert to eassert.
8034 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8051 * window.c (save_window_save): Likewise.
8053 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8055 Do not use Fdelete_overlay in delete_all_overlays
8056 to avoid redundant calls to unchain_overlay.
8057 * buffer.c (drop_overlay): New function.
8058 (delete_all_overlays, Fdelete_overlay): Use it.
8059 * minibuf.c (get_minibuffer): Fix comment.
8061 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8063 Port to OpenBSD 5.1 amd64.
8064 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8065 This is needed for OpenBSD, and should be harmless on all BSD systems.
8066 Also, include <sys/sysctl.h>, as it should be available on all
8067 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8068 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8069 use p_pid member, not kp_proc.pid.
8071 2012-07-06 Glenn Morris <rgm@gnu.org>
8073 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8075 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8077 More xmalloc and related cleanup.
8078 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8079 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
8080 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
8081 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
8082 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
8083 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
8084 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
8085 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8086 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8088 Omit needless casts involving void * pointers and allocation.
8089 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8090 as the former is more robust if P's type is changed.
8091 Prefer xzalloc to xmalloc + memset 0.
8092 Simplify malloc-or-realloc to realloc.
8093 Don't worry about xmalloc returning a null pointer.
8094 Prefer xstrdup to xmalloc + strcpy.
8095 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8097 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8098 alloca of a constant.
8100 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8102 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8103 hscroll is larger than the line width. Fixes long and futile
8104 looping inside extend_face_to_end_of_line (on a TTY) producing
8105 glyphs that are not needed and thrown away.
8107 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8109 * marker.c (set_marker_restricted_both): Simplify by using

8114 * editfns.c (region_limit): Simplify by using clip_to_bounds.
8116 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
8118 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
8119 not defined (Bug#11768).
8120 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
8121 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
8122 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
8123 followed by gtk_box_set_homogeneous (Bug#11768).
8124 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8125 (update_theme_scrollbar_width, xg_create_scroll_bar):
8126 Use gtk_scrollbar_new (Bug#11768).
8127 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8128 (is_box_type): New function (Bug#11768).
8129 (xg_tool_item_stale_p): Call is_box_type.
8130 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8131 with default display (Bug#11768).

8135 * xdisp.c (window_hscroll_limited): New function.
8136 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8137 coordinates when window's hscroll is set to insanely large
8140 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8142 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8143 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
8145 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8148 * lisp.h (xzalloc): New prototype. Omit needless casts.

8203 * fileio.c (time_error_value): Check the right error number.
8204 Problem reported by Troels Nielsen in
8205 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8207 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8209 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8210 This should be fixed in a better way; see Eli Zaretskii in
8211 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8212 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8214 * fileio.c (time_error_value): Rename from special_mtime.
8215 The old name's problems were noted by Eli Zaretskii in
8216 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8218 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8219 This variable's comment says Emacs needs at least one GDB-visible
8220 symbol of type enum pvec_type, to work around GDB problems.
8221 The symbol's value doesn't matter.
8223 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8224 that causes compilation to fail on pre-C99 compilers.
8226 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8228 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8229 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8231 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8233 * buffer.c (init_buffer_once): Fix initialization of
8234 headers for buffer_defaults and buffer_local_symbols.
8235 Reported by Juanma Barranquero <lekktu@gmail.com>.
8237 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8239 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8240 * lisp.h (enum pvec_type): Use fewer bits.
8241 (PSEUDOVECTOR_SIZE_BITS): New constant.
8242 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8243 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8244 change in pvec_type.
8245 (PSEUDOVECTOR_TYPEP): New macro.
8246 (TYPED_PSEUDOVECTORP): Use it.
8247 * fns.c (internal_equal): Adapt code to extract pvectype.

8249 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8250 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8251 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8252 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8253 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8254 abusing vector->header.next.nbytes.
8255 (live_vector_p): Use PVEC_TYPE.
8256 (mark_object): Adapt code to extract pvectype. Use switch.
8258 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8260 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8261 Tighten new eassert a bit.
8263 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8265 Fix compilation with --enable-gcc-warnings and -O1
8267 * doprnt.c (doprnt): Change type of tem to int, initialize
8268 to avoid compiler warning. Add eassert.
8269 * search.c (simple_search): Initialize match_byte to avoid
8270 compiler warning. Add eassert.
8272 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8274 Avoid weird behavior with large horizontal scrolls.
8275 Without this change, for example, large hscroll values would
8276 mess up Emacs's display on Fedora 15 x86, presumably due to
8277 overflows in int calculations in the display code.
8278 Also, if buffers had long lines, Emacs would freeze.
8279 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8280 (set_window_hscroll): New function, containing the old guts of
8281 Fset_window_hscroll. Return the clipped value.
8282 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8283 This avoids the need to check against PTRDIFF_MAX.
8285 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8287 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8289 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8291 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8293 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8294 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8295 since GCC 4.4.6 issues a bogus warning for them.
8297 Fix bugs in file timestamp newness comparisons.
8298 * fileio.c (Ffile_newer_than_file_p):
8299 * lread.c (Fload): Use full timestamp resolution of files,
8300 not just the 1-second resolution, so that files that are only
8301 slightly newer still count as newer.
8302 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8303 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8305 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8307 * fileio.c: Improve handling of file time marker. (Bug#11852)
8308 (special_mtime): New function.
8309 (Finsert_file_contents, Fverify_visited_file_modtime):
8310 Use it to set special mtime values consistently.
8312 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8314 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8315 marker for non-existing file. (Bug#11852)
8317 2012-07-03 Glenn Morris <rgm@gnu.org>
8319 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8320 and did not make it into globals.h).
8322 2012-07-03 Tom Tromey <tromey@redhat.com>
8324 * window.c (Fset_window_margins, Fset_window_fringes)
8325 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8326 * textprop.c (Fprevious_property_change): No longer static.
8327 * syntax.c (Fsyntax_table_p): No longer static.
8328 * process.c (Fget_process, Fprocess_datagram_address): No longer

8349 * intervals.h: Remove EXFUNs.
8350 * fontset.h: Remove EXFUN.

8355 * w32term.h: Remove EXFUNs.
8356 * window.h: Remove EXFUNs.

8358 * xterm.h: Remove EXFUN.
8360 2012-07-03 Glenn Morris <rgm@gnu.org>
8362 * lisp.h (Frandom): Make it visible to C.
8363 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8364 buffer for invisible buffers. (Bug#1229)
8366 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8368 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8369 values which aren't power of 2.
8370 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8371 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8374 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8376 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8378 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8380 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8382 * alloc.c (allocate_vector_block): Remove redundant
8383 calls to mallopt if DOUG_LEA_MALLOC is defined.
8384 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8385 avoid calls to mallopt if zero_vector is returned.
8387 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8389 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8390 is enabled, avoid dereferencing NULL current_sblock if
8393 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8395 Cleanup basic buffer management.
8396 * buffer.h (struct buffer): Change layout to use generic vector
8397 marking code. Fix some comments. Change type of 'clip_changed'
8398 to bitfield. Remove unused #ifndef old.
8399 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8400 (GET_OVERLAYS_AT): Fix indentation.
8401 (for_each_per_buffer_object_at): New macro.

8405 * alloc.c (allocate_buffer): Adjust to match new layout of
8406 struct buffer. Fix comment.
8407 (mark_overlay): New function.
8408 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8409 Lisp area of struct buffer.
8410 (mark_object): Use it. Adjust marking of misc objects
8411 and related comments.
8413 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8415 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8416 wrapper that is not needed because the wrapped code is a no-op (zero
8417 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8418 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8420 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8422 * alloc.c (mark_buffer): Simplify. Remove prototype.
8423 (mark_object): Add comment. Reorganize marking of vector-like
8424 objects. Use CHECK_LIVE for all vector-like objects except buffers
8425 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8426 Avoid redundant calls to mark_vectorlike for bool vectors.
8428 2012-06-30 Glenn Morris <rgm@gnu.org>
8430 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8432 * epaths.in (PATH_SITELOADSEARCH): New.
8433 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8434 This is rather than relying on --enable-locallisppath elements
8435 having "site-lisp" in their names. (Bug#10208#25, 11658)
8437 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8439 * w32proc.c (sys_select): Accept and ignore one more argument.
8441 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8443 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8444 (pselect) [!MS_DOS]: Redirect to sys_select.
8446 * sysdep.c: Don't include dos.h and dosfns.h.
8448 * process.c (sys_select):
8449 * msdos.c (sys_select): Accept one more argument and ignore it.
8451 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8452 adapt data types and code to that.
8455 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8456 which clashes with the gnulib function of the same name.
8458 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8460 * font.c (font_style_to_value, font_style_symbolic)
8461 (font_prop_validate_style): Add type checks for values in
8464 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8466 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8469 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8471 * xdisp.c (try_window_id): Undo last change.
8473 * w32.c (getwd): Adjust commentary about startup_dir.
8474 (init_environment): Always call sys_access, even in non-MSVC
8475 builds. Don't chdir to the directory of the Emacs executable.
8476 This undoes code from 1997 which was justified by the need to
8477 "avoid conflicts when removing and renaming directories". But its
8478 downside was that every relative file name was being interpreted
8479 relative to the directory of the Emacs executable, which can never
8480 be TRT. In particular, it broke sys_access when called with
8481 relative file names.
8482 (sys_access): Map GetLastError to errno.
8484 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8486 * window.h (struct window): Change type of 'fringes_outside_margins'

8490 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8493 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8495 * gnutls.c (emacs_gnutls_handshake):
8496 Add QUIT to make the loop interruptible.
8498 2012-06-29 Glenn Morris <rgm@gnu.org>
8500 * charset.c (init_charset): Make lack of etc/charsets fatal.
8502 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8504 * editfns.c (region_limit): Fix type mismatch.
8506 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8508 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8509 undefined. Convert from xassert to eassert.
8510 * nsmenu.m: Convert from xassert to eassert.
8511 * nsterm.m: Likewise.
8513 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8515 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8517 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8519 Avoid integer overflow on scroll-left and scroll-right.
8520 * window.c (HSCROLL_MAX): New macro.
8521 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8522 overflow when requested scroll falls outside ptrdiff_t range.
8524 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8526 * window.h (struct window): Change type of 'hscroll',
8527 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8528 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8529 Adjust users accordingly.
8530 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8531 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8532 from EMACS_INT to ptrdiff_t.
8533 (make_window): Omit redundant initialization.
8535 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8539 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8541 * window.h (struct window): Change type of 'use_time' and
8542 'sequence_number' from Lisp_Object to int.

8550 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
8551 enabled with --enable-checking=[all,glyphs] configure option.
8552 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8553 adjust comments accordingly.

8674 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8676 Use sprintf return value instead of invoking strlen on result.
8677 In the old days this wasn't portable, since some sprintf
8678 implementations returned char *. But they died out years ago and
8679 Emacs already assumes sprintf returns int.
8680 Similarly for float_to_string.
8681 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8682 * ccl.c (ccl_driver):
8683 * character.c (string_escape_byte8):

8688 * xfns.c (syms_of_xfns):
8689 Use sprintf or float_to_string result to avoid need to call strlen.
8690 * data.c (Fnumber_to_string):
8691 Use make_unibyte_string, since the string must be ASCII.
8692 * lisp.h, print.c (float_to_string): Now returns int length.
8693 * term.c (produce_glyphless_glyph):
8694 Use sprintf result rather than recomputing it.
8696 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8697 * Makefile.in (ALL_CFLAGS):
8698 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8720 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
8722 * gtkutil.c (get_utf8_string): Remove redundant assignment.
8723 sprintf already null-terminates its output.
8725 * xfns.c (x_window): Remove redundant cast.
8727 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8729 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
8730 `const char *' to `char *' to avoid compiler warning.
8732 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8734 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8735 instead of truncating it to 63 (admittedly a generous limit).
8737 * process.c: Fix spelling and caps in comments.
8739 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
8741 * emacs.c (setpgrp): Remove definition, unused.

8788 Remove unnecessary forward decls.
8790 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8792 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

8794 * dispnew.c (Fsleep_for, sit_for):
8795 * keyboard.c (kbd_buffer_get_event):
8796 * process.c (Faccept_process_output):
8797 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8798 This improves on the previous patch, which introduced a bug
8799 when time_t is unsigned and as wide as intmax_t.
8800 See <http://bugs.gnu.org/9000#51>.
8802 2012-06-23 Eli Zaretskii <eliz@gnu.org>

8818 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
8819 Privately reported by Herbert J. Skuhra.
8820 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
8822 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
8823 not make_lisp_timeval, when the argument is of type EMACS_TIME.
8825 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8827 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
8828 last argument of make_unibyte_string.
8830 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
8831 language ID in the event parameters.
8833 * w32term.c (w32_read_socket): Put the new keyboard codepage into
8834 event.code, not the obscure "character set ID".

8857 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
8858 Privately reported by Herbert J. Skuhra.

8865 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8867 Support higher-resolution time stamps (Bug#9000).
8868 The time stamps are only nanosecond-resolution at the C level,
8869 since that's the best that any real-world system supports now.
8870 But they are picosecond-resolution at the Lisp level, as that's
8871 easy, and leaves room for future OS improvements.
8873 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8876 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8877 Don't get current time unless it's needed.
8879 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8880 now provides it if it's absent.
8881 (start_atimer): Port to higher-res time stamps.
8882 Check for time stamp overflow. Don't get current time more
8883 often than is needed.
8885 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8886 Include systime.h, not time.h.
8887 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8889 * dired.c: Include stat-time.h.
8890 (Ffile-attributes): File times now have higher resolution.
8892 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8893 (struct image): Timestamp now has higher resolution.
8895 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8896 has at least microseconds now. All uses removed.
8897 (update_frame, update_single_window, update_window, update_frame_1)
8898 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8899 (duration_to_sec_usec): Remove; no longer needed.
8901 * editfns.c (time_overflow): Now extern.
8902 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8903 (float-time, Fformat_time_string, Fcurrent_time_string)

8907 (decode_time_components, lisp_seconds_argument): New functions.
8908 (make_time): Now static.
8909 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8910 Report an error if the time is invalid, rather than having the caller
8913 * fileio.c: Include <stat-time.h>
8914 (Fcopy_file): Copy higher-resolution time stamps.
8915 Prefer to set the time stamp via a file descriptor if that works.

8917 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8918 (Fvisited_file_modtime, Fset_visited_file_modtime):
8919 Support higher-resolution time stamps.
8921 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8923 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8925 * image.c (prepare_image_for_display, clear_image_cache)
8926 (lookup_image): Port to higer-resolution time stamps.
8928 * keyboard.c (start_polling, bind_polling_period):
8929 Check for time stamp overflow.
8930 (read_char, kbd_buffer_get_event, timer_start_idle)
8931 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8932 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8933 Port to higher-resolution time stamps. Do not assume time_t is signed.
8934 (decode_timer): New function. Timers are now vectors of length 9,
8935 not 8, to accommodate the picosecond component.
8936 (timer_check_2): Use it.
8938 * nsterm.m (select_timeout, timeval_subtract): Remove.
8939 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8940 as they're a bit more accurate and handle overflow better.
8941 (ns_select): Change prototype to be compatible with pselect.
8942 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8943 * nsterm.h (ns_select): Adjust prototype.
8945 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8946 us-resolution time stamps.
8947 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8949 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8951 * lisp.h (time_overflow): New decl.
8952 (wait_reading_process_output): First arg is now intmax_t, not int,
8953 to accommodate larger waits.
8955 * process.h (struct Lisp_Process.read_output_delay):
8956 Now counts nanoseconds, not microseconds.
8957 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8959 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8960 (wait_reading_process_output):
8961 Port to ns-resolution time stamps.
8962 (Faccept_process_output, wait_reading_process_output):
8963 Check for time stamp overflow. Do not assume time_t is signed.
8964 (select_wrapper): Remove; we now use pselect.
8965 (Fprocess_attributes): Now generates ns-resolution time stamps.
8967 * sysdep.c: Include utimens.h. Don't include utime.h
8968 or worry about struct utimbuf; gnulib does that for us now.
8969 (gettimeofday): Remove; gnulib provides a substitute.
8970 (make_timeval): New function.
8971 (set_file_times): Now sets ns-resolution time stamps.
8972 New arg FD; all uses changed.
8973 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8974 (system_process_attributes):
8975 Now returns ns-resolution time stamp. All uses changed.
8976 Check for time stamp overflow.
8978 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8979 provides a substitute now.
8981 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8982 since it guarantees struct timespec.
8983 (EMACS_TIME): Now struct timespec, so that we can support
8984 ns-resolution time stamps.
8985 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8986 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8987 (EMACS_USECS): Remove.
8988 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8989 so multiply the arg by 1000 before storing it.
8990 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8992 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8993 Port to ns-resolution time stamps.
8994 (EMACS_TIME_NEG_P): Remove; replaced by....
8995 (EMACS_TIME_SIGN): New macro.
8996 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8997 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

8999 (make_timeval, make_lisp_time, decode_time_components): New decls.
9000 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9001 that it mishandled time_t overflow. You can't compare by subtracting!
9002 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9003 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9005 * term.c: Include <sys/time.h>.
9006 (timeval_to_Time): New function, for proper overflow wraparound.
9007 (term_mouse_position, term_mouse_click): Use it.

9011 (Fprimitive_undo): Use them when restoring time stamps.
9013 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9014 (w32_get_internal_run_time):
9015 Port to higher-resolution Emacs time stamps.
9016 (ltime): Now accepts single 64-bit integer, as that's more convenient
9019 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9021 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9022 for compatibility with pselect. Support ns-resolution time stamps.
9024 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9026 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9027 Check for time stamp overflow, and support ns-resolution time stamps.
9029 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9030 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9031 (timeval_subtract): Remove; no longer needed.
9032 (XTflash, XTring_bell, x_wait_for_event):
9033 Port to ns-resolution time stamps. Don't assume time_t is signed.
9035 2012-06-22 Chong Yidong <cyd@gnu.org>
9037 * xdisp.c (x_consider_frame_title): Revert last change.
9039 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9041 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9042 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9043 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9044 staticidx goes up to 1597 out of 1600 = 0x640.)
9046 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9048 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9049 Otherwise, the umask might be mistakenly 0 while handling input signals.
9051 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9053 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9059 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9060 access to `contents' member of Lisp_Vector objects with AREF and ASET

9316 code works fine either way, and efficiency is not a concern here,
9317 as the union type is for debugging, not for production.
9318 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9319 Use an inline function on all platforms when using the union type,
9320 since this is simpler and 'static inline' can be used portably

9464 * doprnt.c (doprnt): Truncate multibyte char correctly.
9465 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9466 would mishandle a string argument "Xc" if X was a multibyte
9467 character of length 2: it would truncate after X's first byte
9468 rather than including all of X.

9549 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9550 Use 'float' consistently, rather than 'float' in most places
9551 and 'double' in a couple of places.
9553 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9555 * xdisp.c (handle_stop): Detect whether we have overlay strings
9556 loaded by testing it->current.overlay_string_index to be
9557 non-negative, instead of checking whether n_overlay_strings is
9558 positive. (Bug#11587)
9560 2012-05-31 Chong Yidong <cyd@gnu.org>
9562 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9564 * doc.c (Fsubstitute_command_keys): Doc fix.
9566 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9568 * search.c (search_buffer): Remove calls to
9569 r_alloc_inhibit_buffer_relocation, as it is now called by
9570 maybe_unify_char, which was the cause of relocation of buffer text
9573 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9575 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9576 for the duration of call to load_charset, to avoid problems with
9577 callers of maybe_unify_char that access buffer text through C
9580 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9581 decrement the inhibition flag, instead of just setting or
9584 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9586 Remove obsolete '#define static' cruft.
9587 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9588 This #undef was "temporary" in 2000; it is no longer needed
9589 now that '#define static' has gone away.
9590 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9591 (gray_bitmap_bits): Remove; no longer needed.
9592 All uses replaced with definiens.
9593 * xterm.c: Include "bitmaps/gray.xbm".
9595 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9597 Clean up __executable_start, monstartup when --enable-profiling.
9598 The following changes affect the code only when profiling.
9599 * dispnew.c (__executable_start): Rename from safe_bcopy.
9600 Define only on platforms that need it.
9601 * emacs.c: Include <sys/gmon.h> when profiling.
9602 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9603 (__executable_start): Remove decl, since lisp.h does it now.
9604 (safe_bcopy): Remove decl; no longer has that name.
9605 (main): Coalesce #if into single bit of code, for simplicity.
9606 Cast pointers to uintptr_t, since standard libraries want integers
9608 * lisp.h (__executable_start): New decl.
9610 2012-05-31 Glenn Morris <rgm@gnu.org>
9612 * image.c (Fimagemagick_types): Doc fix.
9614 2012-05-30 Jim Meyering <meyering@redhat.com>
9616 * callproc.c (Fcall_process_region): Include directory component
9617 in mkstemp error message (Bug#11586).

9628 * data.c (Fdefalias): Purify definition, except for keymaps.
9629 (Qdefun): Move from eval.c.
9630 * lisp.h (Qdefun): Remove.
9631 * lread.c (read1): Tiny simplification.
9633 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9635 Do not create empty overlays with the evaporate property (Bug#9642).
9636 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9637 Bug#9642, but explicitly check that the buffer the overlay would
9638 be moved to is live and rearrange lines to make sure that errors
9639 will not put the overlay in an inconsistent state.
9640 (Fdelete_overlay): Cosmetics.
9642 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9644 * w32term.c (my_bring_window_to_top): New function.
9645 (x_raise_frame): Use handle returned by DeferWindowPos, which
9646 could be different from the original one.
9647 Call my_bring_window_to_top instead of my_set_foreground_window.
9650 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9651 by calling BringWindowToTop.
9653 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9654 (WM_EMACS_END): Increase by one.
9656 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9658 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9659 This avoids undefined behavior that might cause the eassert
9660 to not catch an out-of-range value.
9662 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9664 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9665 Update dependencies.
9667 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9669 * bidi.c (bidi_mirror_char): Fix last change.
9671 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9673 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9674 when referring to sectname field in printf format.
9676 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9678 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9679 Only r_alloc_inhibit_buffer_relocation needed to be added;
9680 the others were already declared.
9682 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9683 before checking whether it's out of range. Put the check inside
9685 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9687 2012-05-27 Ken Brown <kbrown@cornell.edu>
9689 * callproc.c (Fcall_process): Restore a line that was accidentally
9690 commented out in the 2011-02-13 change (bug#11547).
9692 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9694 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9695 defined on ralloc.c.
9697 * buffer.c [REL_ALLOC]: Remove prototypes of
9698 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9699 they are now on lisp.h.
9701 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9703 * search.c (search_buffer): Use it to inhibit relocation of buffer
9704 text while re_search_2 is doing its job, because re_search_2 is
9705 passed C pointers to buffer text. (Bug#11519)
9707 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9710 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9711 state after an additional call to move_it_in_display_line_to, keep
9712 the values of it->max_ascent and it->max_descent found for the
9714 (pos_visible_p): Revert the comparison against bottom_y to what it
9715 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9718 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9720 Fix coding-related core dumps with gcc -ftrapv.
9721 The code was computing A - B, where A and B are pointers, and B is
9722 random garbage. This can lead to core dumps on platforms that
9723 have special pointer registers, and it also leads to core dumps on
9724 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9725 A - B only when B is initialized properly.
9726 * coding.c (coding_set_source, coding_set_destination): Return void.
9727 (coding_change_source, coding_change_destinations): New functions,
9728 with the old behaviors of coding_set_source and coding_set_destination.
9729 All callers that need an offset changed to use these new functions.
9731 2012-05-26 Glenn Morris <rgm@gnu.org>
9733 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9735 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9737 Extend mouse support on W32 text-mode console.
9738 * xdisp.c (draw_row_with_mouse_face):
9739 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9741 * w32console.c: Include window.h.
9742 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9744 (initialize_w32_display): Initialize mouse-highlight data.
9746 * w32inevt.c: Include termchar.h and window.h.
9747 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9748 moves, call note_mouse_highlight. If help_echo changed, call
9749 gen_help_event to produce help-echo message in the echo area.
9750 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9753 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9755 * lread.c (read1): Simplify slightly to avoid an overflow warning
9756 with GCC 4.7.0 on x86-64.
9758 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9760 * bidi.c (bidi_mirror_char): Revert last change: an int is
9761 definitely wide enough here.
9763 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9765 Fix integer width and related bugs (Bug#9874).
9766 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9767 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
9768 (string_bytes, check_sblock, allocate_string_data):

9771 (make_string_from_bytes, make_specified_string)
9772 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
9773 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9775 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9776 (allocate_pseudovector):
9777 Use int, not EMACS_INT, where int is wide enough.
9778 (inhibit_garbage_collection, Fgarbage_collect):
9779 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9780 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9781 int might not be wide enough.
9782 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9783 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
9784 (bidi_at_paragraph_end, bidi_find_paragraph_start)
9785 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9786 (bidi_level_of_next_char, bidi_move_to_visually_next):
9787 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9788 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9789 (Fkill_buffer, Fset_buffer_major_mode)
9790 (advance_to_char_boundary, Fbuffer_swap_text)
9791 (Fset_buffer_multibyte, overlays_at, overlays_in)
9792 (overlay_touches_p, struct sortvec, record_overlay_string)
9793 (overlay_strings, recenter_overlay_lists)
9794 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9795 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9796 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9797 (Foverlay_recenter, last_overlay_modification_hooks_used)
9798 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9799 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9800 (validate_region): Omit unnecessary test for b <= e,
9801 since that's guaranteed by the previous test.
9802 (adjust_overlays_for_delete): Avoid pos + length overflow.
9803 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9804 (report_overlay_modification):
9805 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9806 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9807 Omit pointer cast, which isn't needed anyway, and doesn't work
9808 after the EMACS_INT -> ptrdiff_t change.
9809 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9810 * buffer.h: Adjust decls to match defn changes elsewhere.
9811 (struct buffer_text, struct buffer):

9813 Use EMACS_INT, not int, where int might not be wide enough.
9814 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9815 not int, to avoid needless 32-bit limit on 64-bit hosts.
9816 (exec_byte_code): Use tighter memory-full test, one that checks
9817 for alloca overflow. Don't compute the address of the object just
9818 before an array, as that's not portable. Use EMACS_INT, not
9819 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9820 * callint.c (Fcall_interactively):
9821 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9822 * callproc.c (call_process_kill, Fcall_process):
9823 Don't assume pid_t fits into an Emacs fixnum.

9826 (call_process_cleanup, Fcall_process, delete_temp_file)
9827 (Fcall_process_region):
9828 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9829 (Fcall_process): Simplify handling of volatile integers.
9830 Use int, not EMACS_INT, where int will do.
9831 * casefiddle.c (casify_object, casify_region, operate_on_word)
9832 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9833 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9834 (casify_object): Avoid integer overflow when overallocating buffer.
9835 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9836 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9837 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9838 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9839 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9840 integers are now checked earlier. All uses replaced with XINT.
9842 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9843 For CCL_MapSingle, check that content and value are in int range.
9844 (ccl_driver, Fregister_code_conversion_map):
9845 Check that Vcode_version_map_vector is a vector.
9846 (resolve_symbol_ccl_program): Check that vector header is in range.
9847 Always copy the vector, so that we can check its contents reliably
9848 now rather than having to recheck each instruction as it's being
9849 executed. Check that vector words fit in 'int'.
9850 (ccl_get_compiled_code, Fregister_ccl_program)
9851 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9852 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9853 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9854 contents are in range.
9855 (Fccl_execute_on_string): Check that status is in range.
9856 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9857 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9858 Accept and return EMACS_INT, not int, because callers can pass values
9860 (c_string_width, strwidth, lisp_string_width, chars_in_text)
9861 (multibyte_chars_in_text, parse_str_as_multibyte)
9862 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
9863 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9864 (string_escape_byte8, Fget_byte):
9865 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9866 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9867 avoid mishandling large integers.
9868 * character.h: Adjust decls to match defn changes elsewhere.
9869 * charset.c (load_charset_map_from_file, find_charsets_in_text)
9870 (Ffind_charset_region):
9871 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9872 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
9873 (load_charset_map_from_vector, Fdefine_charset_internal):
9874 Don't assume fixnum fits in int.
9875 (load_charset_map_from_vector, Fmap_charset_chars):
9876 Remove now-unnecessary CHECK_NATNUMs.
9877 (Fdefine_charset_internal): Check ranges here, more carefully.
9878 Don't rely on undefined behavior with signed left shift overflow.
9879 Don't assume unsigned int fits into fixnum, or that fixnum fits
9880 into unsigned int. Don't require max_code to be a valid fixnum;
9881 that's not true for gb10830 4-byte on a 32-bit host. Allow
9882 invalid_code to be a cons, for the same reason. Require code_offset
9883 to be a character. Avoid int overflow if max_char is close
9885 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9886 this is intended anyway and avoids some undefined behavior.
9887 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9888 INDEX_TO_CODE_POINT, as that's what it expects.
9889 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9890 * charset.h (DECODE_CHAR): Return int, not unsigned;
9891 this is what was intended anyway, and it avoids undefined behavior.
9892 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9893 integer-overflow issues.
9894 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9895 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9896 where the argument is EMACS_INT, and this behavior is not intended.
9897 * chartab.c (Fmake_char_table, Fset_char_table_range)
9898 (uniprop_get_decoder, uniprop_get_encoder):
9899 Don't assume fixnum fits in int.
9900 * cmds.c (move_point): New function, that does the gist of
9901 Fforward_char and Fbackward_char, but does so while checking
9902 for integer overflow more accurately.
9903 (Fforward_char, Fbackward_char): Use it.
9904 (Fforward_line, Fend_of_line, internal_self_insert)
9905 (internal_self_insert):
9906 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9907 Fix a FIXME, by checking for integer overflow when calculating
9908 target_clm and actual_clm.
9909 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

9938 (Funencodable_char_position, Fcheck_coding_systems_region)
9939 (get_translation, handle_composition_annotation, consume_chars):
9940 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9941 (consume_chars): Rewrite to not calculate an address outside buffer.
9942 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
9943 Don't access memory outside of the args array.
9944 (Fdefine_coding_system_internal): Check for charset-id overflow.
9945 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
9946 result of ENCODE_CHAR.
9947 * coding.h: Adjust decls to match defn changes elsewhere.
9948 (struct coding_system):
9949 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10646 2012-05-19 Ken Brown <kbrown@cornell.edu>
10648 * xfns.c (x_in_use): Remove `static' qualifier.
10649 * xterm.h (x_in_use): Declare.
10650 * xgselect.c: Include xterm.h.
10651 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
10652 and `display_arg' (bug#9754).
10654 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
10656 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
10658 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
10659 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
10661 2012-05-18 Eli Zaretskii <eliz@gnu.org>
10663 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
10665 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
10666 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
10668 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
10669 reference to image_cache->refcount.
10670 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10672 2012-05-17 Juri Linkov <juri@jurta.org>
10674 * search.c (Fword_search_regexp, Fword_search_backward)
10675 (Fword_search_forward, Fword_search_backward_lax)
10676 (Fword_search_forward_lax): Move functions to isearch.el
10677 (bug#10145, bug#11381).
10679 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10681 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10683 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10685 * lread.c (init_obarray): Declare Qt and Qnil as special.
10687 2012-05-14 Glenn Morris <rgm@gnu.org>
10689 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10690 Put "libexec" before "bin", for the sake of init_callproc_1.
10692 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10694 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10696 * unexaix.c: Port to more-recent AIX compilers.
10697 (report_error, report_error_1, make_hdr, copy_sym)
10698 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10699 Make arguments const char *, not char *, to avoid violations of C
10700 standard and to fix some AIX warnings reported by Gilles Pion.
10702 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10704 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10705 already have overlays loaded.
10706 (handle_single_display_spec): Before returning without displaying
10707 fringe bitmap, synchronize the bidi iterator with the main display
10708 iterator, by calling iterate_out_of_display_property.
10709 (iterate_out_of_display_property): Detect buffer iteration by
10710 testing that it->string is a Lisp string.
10711 (get_next_display_element): When the current object is exhausted,
10712 and there's something on it->stack, call set_iterator_to_next to
10713 proceed with what's on the stack, instead of returning zero.
10714 (set_iterator_to_next): If called at the end of a Lisp string,
10715 proceed to consider_string_end without incrementing string
10716 position. Don't increment display vector index past the end of
10717 the display vector. (Bug#11417)
10718 (pos_visible_p): Don't report a position visible when move_it_to
10719 stopped at the last line of window, which happens to be scanned
10720 backwards by the bidi iteration. (Bug#11464)
10722 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10724 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10725 and right-margin display specs even if the spec is invalid or we
10726 are on a TTY, and thus unable to display on the fringes.
10727 That's because the text with the property will not be displayed anyway,
10728 so we need to signal to the caller that this is a "replacing"
10729 display spec. This fixes display when the spec is invalid or we
10732 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10734 * unexaix.c (make_hdr): Fix typo in prototype.
10735 This bug broke the build on AIX. Problem reported by Gilles Pion.
10737 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10739 * keyboard.c (kbd_buffer_get_event): Read special events also in
10740 batch mode. (Bug#11415)
10742 2012-05-12 Glenn Morris <rgm@gnu.org>
10744 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10746 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10748 * lisp.mk (lisp): Add newcomment.elc.
10750 2012-05-12 Glenn Morris <rgm@gnu.org>
10752 * Makefile.in (MKDIR_P): New, set by configure.
10753 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10755 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10757 Remove unused function hourglass_started.
10758 * dispextern.h (hourglass_started):
10759 * w32fns.c (hourglass_started):
10760 * xdisp.c (hourglass_started): Remove.
10762 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10764 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10765 Update dependencies.
10767 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10769 * xgselect.c (xg_select): Put maxfds+1 into a var.
10770 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10772 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10774 2012-05-10 Dave Abrahams <dave@boostpro.com>
10776 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10777 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10779 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10781 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10782 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
10783 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10784 Initialize xd_registered_buses.
10786 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10788 Untag more efficiently if USE_LSB_TAG.
10789 This is based on a proposal by YAMAMOTO Mitsuharu in
10790 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10791 For an admittedly artificial (nth 8000 longlist) benchmark on
10792 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10793 Emacs's overall text size by 1%.
10794 * lisp.h (XUNTAG): New macro.
10795 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10796 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10797 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10798 * eval.c (Fautoload):
10799 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10800 * frame.h (XFRAME): Use XUNTAG.
10802 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10803 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10804 Remove unportable assumptions about print widths of types like
10806 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10807 intptr_t when converting between pointer and integer, to avoid GCC
10808 warnings about wrong width.
10810 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10812 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10813 stack for each reader_thread, instead of defaulting to 8MB
10814 determined by the linker. This avoids failures in creating
10815 subprocesses on Windows 7, see the discussion in this thread:
10816 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10818 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10820 Fix up display of the *Minibuf-0* buffer in the mini window.
10821 * keyboard.c (read_char): Don't clear the echo area if there's no
10823 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10824 contents of *Minibuf-0*) if there's no message displayed in its stead.
10826 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10828 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10831 2012-05-06 Chong Yidong <cyd@gnu.org>
10833 * lisp.mk (lisp): Update.
10835 2012-05-05 Jim Meyering <meyering@redhat.com>
10837 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10839 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10841 * data.c (PUT_ERROR): New macro.
10842 (syms_of_data): Use it. Add new error type `user-error'.
10843 * undo.c (user_error): New function.
10844 (Fprimitive_undo): Use it.
10845 * print.c (print_error_message): Adjust print style for `user-error'.
10846 * keyboard.c (user_error): New function.
10847 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10849 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10851 Do not limit current-time-string to years 1000..9999.
10852 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10853 (Fcurrent_time_string): Support any year that is supported by the
10854 underlying localtime representation. Don't use asctime, as it
10855 has undefined behavior for years outside the range -999..9999.
10857 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10859 Fix race conditions involving setenv, gmtime, localtime, asctime.
10860 Without this fix, interrupts could mess up code that uses these
10861 nonreentrant functions, since setting TZ invalidates existing
10862 tm_zone or tzname values, and since most of these functions return
10863 pointers to static storage.
10864 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10865 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10866 Grow the critical sections to include not just invoking
10867 localtime/gmtime, but also accessing these functions' results
10868 including their tm_zone values if any, and any related TZ setting.
10869 (format_time_string): Last arg is now struct tm *, not struct tm **,
10870 so that the struct tm is saved in the critical section.
10871 All callers changed. Simplify allocation of initial buffer, partly
10872 motivated by the fact that memory allocation needs to be outside
10873 the critical section.
10875 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10877 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10878 with RESET_INTERVAL.
10880 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10881 Remove duplicated buffer name initialization.
10883 2012-05-02 Jim Meyering <jim@meyering.net>
10885 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10887 * xfns.c (x_window): Use xstrdup (Bug#11375).
10889 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10891 * xdisp.c (pos_visible_p): If already at a newline from the
10892 display string before the 'while' loop, don't walk back the glyphs
10893 from it3.glyph_row. Solves assertion violation when the display
10894 string begins with a newline (egg.el). (Bug#11367)
10896 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10898 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10901 2012-05-01 Glenn Morris <rgm@gnu.org>
10903 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10904 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10905 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10906 All were removed before 23.1.
10908 * dispnew.c: Remove HAVE_LIBNCURSES test;
10909 it is always true on relevant platforms.
10911 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10912 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10914 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10916 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10918 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10919 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10922 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10924 Do not avoid creating empty evaporating overlays (Bug#9642).
10925 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10926 That is, do not delete an evaporating overlay if it becomes
10927 empty after its bounds are adjusted to fit within its buffer.
10928 This fix caused other problems, and I'm reverting it until we get
10929 to the bottom of them.
10931 2012-04-27 Chong Yidong <cyd@gnu.org>
10933 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10935 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10937 * xdisp.c (pos_visible_p): If the window start position is beyond
10938 ZV, start the display from buffer beginning. Prevents assertion
10939 violation in init_iterator when the minibuffer window is scrolled
10940 via the scroll bar.
10942 * window.c (window_scroll_pixel_based): Likewise.
10944 2012-04-27 Chong Yidong <cyd@gnu.org>
10946 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10948 2012-04-27 Glenn Morris <rgm@gnu.org>
10950 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10951 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10953 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10955 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10956 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10958 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10960 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10961 display element, check also the underlying string or buffer
10962 character. (Bug#11341)
10964 * w32menu.c: Include w32heap.h.
10965 (add_menu_item): If the call to AppendMenuW (via
10966 unicode_append_menu) fails, disable Unicode menus only if we are
10967 running on Windows 9X/Me.
10969 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10971 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10972 (xgetint): Add missing shift for LSB tags.
10974 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10976 * keyboard.c (read_char): Don't wipe echo area for select window
10977 events: These might get delayed via `mouse-autoselect-window'
10980 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10982 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10983 manipulation of :loaded-from data.
10985 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10987 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10988 now a cons (bug#11311).
10990 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10992 Do not create empty overlays with the evaporate property (Bug#9642).
10993 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10994 if it becomes empty after its bounds are adjusted to fit within
10995 its buffer. Without this fix, in a nonempty buffer (let ((o
10996 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10997 yields an empty overlay that has the evaporate property, which is
10998 not supposed to happen.
11000 Fix minor GTK3 problems found by static checking.
11001 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11002 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11003 (struct _EmacsFixedClass, emacs_fixed_get_type):
11004 Move decls here from emacsgtkfixed.h, since they needn't be public.
11005 (emacs_fixed_get_type): Now static.
11006 (emacs_fixed_class_init): Omit unused local.
11007 (emacs_fixed_child_type): Remove; unused.

11009 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11010 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11011 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11012 (EMACS_FIXED_GET_CLASS): Remove; unused.
11013 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11015 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11016 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11018 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11020 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11021 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11022 (__malloc_size_t, __malloc_ptrdiff_t):
11023 Remove. All uses removed, replaced by the definiens if needed,
11024 since we can assume C89 or better now.
11025 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11033 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11034 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11035 Define using prototypes, not old style.
11036 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11037 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11038 (align): Don't assume that signed integer overflow wraps around.
11039 Omit unused local var.
11040 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11041 (_free_internal_nolock, memalign, mallochook, reallochook):
11042 Omit no-longer-needed casts.
11043 (valloc): Use getpagesize, not __getpagesize.
11044 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11045 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11047 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11049 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11051 Move functions from C to Lisp. Make non-blocking method calls
11052 the default. Implement further D-Bus standard interfaces.
11054 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

11070 (xd_signature, xd_append_arg): Allow float for integer types.
11071 (xd_get_connection_references): New function.
11072 (xd_get_connection_address): Rename from xd_initialize.
11073 Return cached address.
11074 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.

11111 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
11113 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11115 * sysdep.c [__FreeBSD__]: Minor cleanups.
11116 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11117 Use Emacs indenting style more consistently. Avoid some casts.

11122 * sysdep.c (list_system_processes, system_process_attributes):
11123 Add implementation for FreeBSD (Bug#5243).

11129 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11131 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11132 It is never used otherwise.
11134 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11136 * print.c (print_preprocess): Only check print_depth if print-circle
11138 (print_object): Check for cycles even when print-circle is nil and
11139 print-gensym is t, but only check print_depth if print-circle is nil.
11141 2012-04-20 Chong Yidong <cyd@gnu.org>
11143 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11144 set the status to "failed" and ensure that sentinel is run.
11146 2012-04-20 Glenn Morris <rgm@gnu.org>
11148 * process.c (Fset_process_inherit_coding_system_flag)
11149 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11177 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11178 -Wunused-result, -Wunused-variable. This should go away once
11179 the Emacs and Gnulib regex code is merged.
11180 (xmalloc, xrealloc): Now static.
11182 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

11199 New extern decls, to avoid calling undeclared functions.
11200 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11201 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11202 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11203 (NEED_MEM_INSERT): New macro.
11204 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11205 Remove one incorrect comment and fix another.

11219 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
11220 Remove decls. This fixes an "It stinks!".
11222 * alloc.c (which_symbols): Fix alignment issue / type clash.
11224 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11226 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11227 (struct Lisp_Misc_Any): Likewise.
11228 (struct Lisp_Free): Likewise.
11229 * alloc.c (union aligned_Lisp_Symbol): Define.

11241 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11242 * s/netbsd.h, s/sol2-6.h:
11243 Remove definition of GC_MARK_STACK, since the default now works.
11244 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11245 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11246 no longer the default.
11247 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11249 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11251 * lread.c (lisp_file_lexically_bound_p):
11252 Fix hang at ";-*-\n" (bug#11238).
11254 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11256 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
11257 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

11268 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11270 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11272 2012-04-11 Daniel Colascione <dancol@dancol.org>
11274 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11275 against is gone. It's better to use vfork now so that when Cygwin
11276 gains a new, working vfork, we use it automatically (bug#10398).
11278 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11280 * window.c (save_window_save): Obey window-point-insertion-type.

11298 * w32.c (w32_delayed_load): Record the full path of the library
11299 being loaded (bug#10424).
11301 2012-04-09 Glenn Morris <rgm@gnu.org>
11303 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11304 not just in the obarray, before snarfing them. (Bug#11036)

11321 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11322 attempts per process (connection).
11324 2012-04-09 Chong Yidong <cyd@gnu.org>
11326 * eval.c (Fuser_variable_p, user_variable_p_eh)

11328 (Fdefvar): Caller changed.
11330 * callint.c (Finteractive, Fcall_interactively):
11331 * minibuf.c (Fread_variable): Callers changed.
11333 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11335 * xdisp.c (set_cursor_from_row): If the display string appears in
11336 the buffer at position that is closer to point than the position
11337 after the display string, display the cursor on the first glyph of
11338 the display string. Fixes cursor display when a 'display' text
11339 property immediately follows invisible text. (Bug#11094)
11341 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11343 composite.c: use 'double' consistently
11344 * composite.c (get_composition_id): Use 'double' consistently
11345 instead of converting 'float' to 'double' and vice versa; this is
11346 easier to understand and avoids a GCC warning.
11348 2012-04-09 Glenn Morris <rgm@gnu.org>
11350 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11351 preparation for dumping it with emacs. (Bug#4789)

11373 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11374 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11375 objects, as mark_maybe_pointer will catch them otherwise.
11376 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11377 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

11390 ($(BLD)/xml.$(O)): New dependency list.
11392 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11393 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11394 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11395 [!WINDOWSNT]: New macros.
11396 (init_libxml2_functions, libxml2_loaded_p): New functions.
11397 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11398 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11399 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11400 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11402 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11403 Call init_libxml2_functions before calling libxml2 functions.
11404 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11406 * emacs.c: Don't include libxml/parser.h.
11407 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11408 xmlCleanupParser directly.

11412 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11414 * indent.c (Fvertical_motion): If there is a display string at
11415 point, use it.vpos to compute how many lines to backtrack after
11416 move_it_to point. (Bug#11133)
11418 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11420 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11421 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11422 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11423 macros related to unification of CJK characters. For the details,
11424 see the discussion following the message here:
11425 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11427 2012-04-04 Chong Yidong <cyd@gnu.org>
11429 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11431 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11433 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

11441 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11443 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11444 position we get to after a call to move_it_to fails the
11445 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11446 only if we wind up in a string from display property. (Bug#11063)
11448 * window.c (Fdelete_other_windows_internal): Invalidate the row
11449 and column information about mouse highlight, so that redisplay
11450 restores it after reallocating the glyph matrices. (Bug#7464)
11452 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11453 string comes from a `display' text property, use the buffer
11454 position of that property as if we actually saw that position in
11456 (move_it_by_lines): Remove the assertion that
11457 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11458 violated when there's a before-string at the beginning of a line.
11461 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11463 * xdisp.c (append_space_for_newline): If the default face was
11464 remapped, use the remapped face for the appended newline.
11465 (extend_face_to_end_of_line): Use the remapped default face for
11466 extending the face to the end of the line.
11467 (display_line): Call extend_face_to_end_of_line when the default
11468 face was remapped. (Bug#11068)
11470 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11472 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11474 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

11490 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11491 (command_loop_1): Use it; inhibit selection update for

11496 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11498 2012-03-25 Kenichi Handa <handa@m17n.org>
11500 * dispextern.h (struct glyph): Change the bit length of
11501 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11503 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11505 * s/ms-w32.h (tzname): Include time.h before redirecting to

11514 !SYNC_INPUT. (Bug#11080)
11516 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11518 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11519 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11520 when fetching a multibyte character consumes more bytes than
11521 CHAR_BYTES returns, due to unification of CJK characters in
11522 string_char. (Bug#11073)
11524 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11526 * process.c (wait_reading_process_output): Handle pty disconnect
11527 by refraining from sending oneself a SIGCHLD (bug#10933).
11529 2012-03-22 Chong Yidong <cyd@gnu.org>
11531 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11533 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11534 Mark string as coming from a prefix property.
11535 (handle_face_prop): Use default face for prefix strings (Bug#4281).

11556 it fit in a valid range (Bug#11003).
11558 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11560 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11561 that is not from display property, accept the row as a "cursor
11562 row" if one of the string's character has a non-nil `cursor'
11563 property. Fixes cursor positioning when there are newlines in
11564 overlay strings, e.g. in icomplete.el. (Bug#11035)
11566 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

11597 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11600 2012-03-03 Glenn Morris <rgm@gnu.org>
11602 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11604 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11615 * buffer.c (buffer-list-update-hook): Doc fix.
11617 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11619 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11620 push_it before setting up the iterator for the first overlay
11621 string, even if we have an empty string loaded.
11622 (next_overlay_string): If there's an empty string on the iterator
11623 stack, pop the stack. (Bug#10903)
11625 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11627 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11628 Suggested by Stefan Monnier in
11629 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11630 * alloc.c (widen_to_Lisp_Object): New static function.
11631 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11632 and widening them to Lisp_Objects. This would work even if
11633 USE_LSB_TAG is defined and wide integers are used, which might
11634 happen in a future version of Emacs.
11636 2012-02-25 Chong Yidong <cyd@gnu.org>
11638 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

11643 before saving to clipboard manager.
11645 2012-02-24 Chong Yidong <cyd@gnu.org>
11647 * keyboard.c (process_special_events): Handle all X selection
11648 requests in kbd_buffer, not just the next one (Bug#8869).
11650 2012-02-23 Chong Yidong <cyd@gnu.org>
11652 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11653 call when setting menu-bar-lines and tool-bar-lines parameters.
11654 (unwind_create_frame_1): New helper function.
11656 * window.c (inhibit_window_configuration_change_hook): New var.
11657 (run_window_configuration_change_hook): Obey it.

11675 when computing $valmask.
11677 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11678 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11679 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11680 It's useless in that case, and it can cause problems on hosts
11681 that allocate halves of EMACS_INT values separately.
11682 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11683 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11684 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11685 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11686 it avoids undefined behavior on hosts where shifting right by more
11687 than the word width has undefined behavior.
11689 2012-02-19 Chong Yidong <cyd@gnu.org>
11691 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11692 (Funhandled_file_name_directory, Ffile_name_as_directory)
11693 (Fdirectory_file_name, Fexpand_file_name)
11694 (Fsubstitute_in_file_name): Protect against invalid file handler
11695 return values (Bug#10845).

11709 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11711 2012-02-15 Chong Yidong <cyd@gnu.org>
11713 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11714 marked as special. Also, starting docstrings with * is obsolete.

11729 2012-02-12 Chong Yidong <cyd@gnu.org>
11731 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11732 as that creates a dangerous corner case.
11734 * window.c (Fdelete_window_internal): Invalidate the mouse
11735 highlight (Bug#9904).
11737 2012-02-12 Glenn Morris <rgm@gnu.org>

11742 * nsselect.m (Fx_own_selection_internal)
11743 (Fx_disown_selection_internal, Fx_selection_exists_p)
11744 (Fx_selection_owner_p, Fx_get_selection_internal):

11767 2012-02-07 Chong Yidong <cyd@gnu.org>
11769 * buffer.c (Fbuffer_local_variables)
11770 (buffer_lisp_local_variables): Handle unbound vars correctly;
11771 don't let Qunbound leak into Lisp.
11773 2012-02-07 Glenn Morris <rgm@gnu.org>
11775 * image.c (Fimagemagick_types): Doc fix.
11777 * image.c (imagemagick-render-type): Change it from a lisp object
11778 to an integer. Move the doc here from the lisp manual.

11795 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11797 * w32.c (get_emacs_configuration_options):
11798 Include --enable-checking, if specified, in the return value.

11808 before BEGV. (Bug#10696)
11810 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11812 Handle overflow when computing char display width (Bug#9496).
11813 * character.c (char_width): Return EMACS_INT, not int.
11814 (char_width, c_string_width): Check for overflow when
11815 computing the width; this is possible now that individual
11816 characters can have unbounded width. Problem introduced
11817 by merge from Emacs 23 on 2012-01-19.

11841 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11843 (x_produce_glyphs): If the component of a composition is a null
11844 string, set it->pixel_width to 1 to avoid zero-width glyph.

11848 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11849 first 2 arguments are identical. This makes inserting large
11850 output from a subprocess an order of magnitude faster on
11851 MS-Windows, where all sbrk'ed memory is always contiguous.
11853 2012-01-31 Glenn Morris <rgm@gnu.org>

11948 2012-01-09 Eli Zaretskii <eliz@gnu.org>
11950 * xdisp.c (rows_from_pos_range): Accept additional argument
11951 DISP_STRING, and accept any glyph in a row whose object is that
11952 string as eligible for mouse highlight. Fixes mouse highlight of
11953 display strings from overlays. (Bug#10464)
11955 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
11957 emacs: fix an auto-save permissions race condition (Bug#10400)

11959 (Fmake_directory_internal): Use it.
11960 (do_auto_save_make_dir): Set it, instead of invoking chmod after

11964 (Fdo_auto_save): Catch all errors, not just file errors, so
11965 that the var is always cleared.

12304 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12305 verifies glyph row's hash code--we have just reallocated the

12467 Otherwise, valgrind does not work on some platforms.
12468 Problem reported by Andreas Schwab in
12469 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12470 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12471 is set, removing the need for VIRT_ADDRESS_VARIES.
12472 (PURE_P): Use a more-efficient implementation that needs just one
12473 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12474 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12475 to 4 (xorl, subq, cmpq, setbe).
12476 * alloc.c (pure): Always extern now, since that's the
12477 VIRT_ADDR_VARIES behavior.
12478 (PURE_POINTER_P): Use a single comparison, not two, for
12479 consistency with the new puresize.h.
12480 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12481 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
12482 Remove VIRT_ADDR_VARIES no longer needed.
12484 2011-11-19 Eli Zaretskii <eliz@gnu.org>
12486 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
12487 (erase_phys_cursor, update_window_cursor, show_mouse_face)

12950 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
12951 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
12952 (g_b_init_get_glyph_outline_w): New static variables.
12953 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
12954 (GetGlyphOutlineW_Proc): New typedefs.
12955 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
12956 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
12958 (w32font_open_internal, compute_metrics):
12959 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12960 instead of calling the "wide" APIs directly.
12962 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
12964 * w32.h (syms_of_w32font): Add prototype.
12966 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12968 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
12969 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
12970 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
12971 (Fmove_to_window_line): Doc fix.
12973 2011-10-27 Chong Yidong <cyd@gnu.org>
12975 * process.c (make_process): Set gnutls_state to NULL.
12977 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
12978 non-NULL, regardless of GNUTLS_INITSTAGE.
12979 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
12980 an error. Set process slots as soon as we allocate them.
12982 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
12984 2011-10-27 Chong Yidong <cyd@gnu.org>
12986 * gnutls.c (emacs_gnutls_deinit): New function.
12987 Deallocate credentials structures as well as calling gnutls_deinit.
12988 (Fgnutls_deinit, Fgnutls_boot): Use it.
12990 * process.c (make_process): Initialize GnuTLS credentials to NULL.
12991 (deactivate_process): Call emacs_gnutls_deinit.
12993 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12995 * image.c (x_create_x_image_and_pixmap):
12996 * w32.c (sys_rename, w32_delayed_load):
12997 * w32font.c (fill_in_logfont):
12998 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13000 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13002 * w32fns.c (w32_default_color_map): New function,
13003 extracted from Fw32_default_color_map.
13004 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13006 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13008 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13010 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13012 * keyboard.c (test_undefined): New function (bug#9751).
13013 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13015 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13017 * sysdep.c (init_sys_modes): Fix the check for the controlling
13018 terminal (Bug#6649).
13020 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13022 * dispextern.h (struct bidi_it): New member next_en_type.
13024 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13025 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13026 current character, check also for next_en_type being WEAK_EN.
13027 (bidi_resolve_weak): Don't enter the expensive loop if the current
13028 position is before next_en_pos. Record the bidi type of the first
13029 non-ET, non-BN character we find, in addition to its position.
13030 (bidi_level_of_next_char): Invalidate next_en_type when
13031 next_en_pos is over-stepped.
13033 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13035 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13036 * editfns.c: Rewrite current-time-zone so that it invokes
13037 the equivalent of (format-time-string "%Z") to get the time zone name.
13038 This fixes a bug when the time zone name contains characters that
13039 need converting from the system time locale to Emacs internal format.
13040 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13041 that patch fixed format-time-string to do the conversion, but
13042 I forgot to fix current-time-zone.
13043 (format_time_string): New function, containing most of
13044 what Fformat_time_string used to contain.
13045 (Fformat_time_string): Rewrite in terms of format_time_string.
13046 This doesn't change this function's behavior.
13047 (current-time-zone): Rewrite to use format_time_string.
13048 This fixes the bug reported by Michael Schierl in
13049 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13050 Jason Rumney's 2007-06-07 change worked around this bug, but
13052 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13054 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13056 * xdisp.c (start_display): If the character at POS is displayed
13057 via a display vector, reset IT->current.dpvec_index to zero.
13058 (try_window_reusing_current_matrix): If a line ends in a display
13059 vector or the next line starts in a display vector, continue
13060 redrawing the window even though the character position of
13061 start_row was reached.
13064 2011-10-18 Chong Yidong <cyd@gnu.org>
13066 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13067 with nobreak-char-display too.
13069 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13071 Fix part 3 of bug#9771.
13072 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13073 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13074 non-neutral characters if the current character is a paragraph
13075 separator (a.k.a. Newline). This avoids running the same
13076 expensive loop twice, once when we consume the preceding newline
13077 and the other time when the line actually needs to be displayed.
13078 Avoid the loop when we see neutrals on the base embedding level
13079 following a character whose directionality is the same as the
13080 paragraph's. This avoids running the expensive loop when a line
13081 ends in a long sequence of neutrals, like control characters.
13082 Add assertion against STRONG_AL type. Slightly rearrange code
13083 that determines the type of a neutral given the first non-neutral
13085 (bidi_level_of_next_char): Set next_en_pos to zero when
13086 invalidating its info.
13088 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13090 * xdisp.c (push_display_prop): Determine whether to record string
13091 or buffer position by IT->string, not by IT->method. Allow
13092 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13093 (move_it_vertically_backward): Don't look for character position
13094 immediately after the newline when in a continuation line.
13097 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13099 * window.c (coordinates_in_window): Rewrite and delabelize
13100 vertical border check. (Bug#5357) (Bug#9618)
13102 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13104 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13105 errors in XSetWindowBorder (bug#9310).
13107 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13109 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13110 avoid crash when xmalloc overrun checking is enabled.
13112 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13114 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13115 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13116 cursor motion with <left> and <right> arrow keys.
13118 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13119 some callers set that themselves.
13121 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13123 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13124 display string and the previous row comes from the same string and
13125 is empty. (Bug#9739) (Bug#9738)
13127 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13129 * doc.c (get_doc_string): Encode file name (bug#9735).
13131 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13133 * bidi.c (bidi_level_of_next_char):
13134 * xdisp.c (get_visually_first_element): Remove old incorrect
13135 comments regarding the Unicode Line Separator character.
13137 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13139 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13141 * alloc.c (Fgc_status): Do not access beyond zombies array
13142 boundary if nzombies > MAX_ZOMBIES.
13143 * alloc.c (dump_zombies): Add missing format specifier.
13145 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13147 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13148 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13150 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13151 Some packages use them to denote characters with modifiers.
13153 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13155 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13156 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13157 matching a pp-number. Rename parameter var to var1.
13159 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13161 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13163 2011-10-08 Glenn Morris <rgm@gnu.org>
13165 * callint.c (Fcall_interactively): Give a more explicit error for the
13166 'c' case with a non-character input. (Bug#8479)
13168 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13170 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13172 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13173 lines that are hscrolled on the left.
13175 * dispnew.c (buffer_posn_from_coords): Account for a possible
13176 presence of header-line. (Bug#4426)
13178 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13180 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13181 Don't advertise functionality which we discourage or doesn't work.
13183 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13185 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13186 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13187 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13188 this makes Emacs dump core during garbage collection on rare
13189 occasions. sizeof is obviously inferior to offsetof here, so
13190 stick with offsetof.
13191 (GC_POINTER_ALIGNMENT): New macro.
13192 (mark_memory): Omit 3rd (offset) arg; caller changed.
13193 Don't assume EMACS_INT alignment is the same as pointer alignment.
13195 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13197 * keyboard.c (read_key_sequence_remapped): New var.
13198 (read_key_sequence): Compute remapping in the right buffer.
13199 (command_loop_1): Use read_key_sequence's remapping directly.
13201 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13203 * dired.c (file_name_completion): Don't expand file name.
13204 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13205 before checking file name handler.
13207 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13208 they've been requested explicitly (bug#9591).
13210 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13212 * keymap.c (Fsingle_key_description): Use make_specified_string
13213 instead of build_string to build string from push_key_description.
13216 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13218 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13219 This fixes a Y2038 bug on 64-bit hosts.
13220 * buffer.c (reset_buffer):
13221 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13222 (Fclear_buffer_auto_save_failure):
13223 Use 0, not -1, to represent an unset failure time, since time_t
13224 might not be signed.
13226 Remove dependency on glibc malloc internals.
13227 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13228 Move back here from lisp.h, but with their new implementations.
13229 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13230 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13231 * charset.c (charset_table_init): New static var.
13232 (syms_of_charset): Use it instead of xmalloc. This removes a
13233 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13234 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13235 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13236 Move back to alloc.c.
13237 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13238 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13240 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13242 * nsterm.m (windowDidResize): Call x_set_window_size only when
13243 ns_in_resize is true. Otherwise set pixelwidth/height and
13244 call change_frame_size (Bug#9628).
13246 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13248 Port --enable-checking=all to Fedora 14 x86-64.
13249 * charset.c (syms_of_charset): Also account for glibc malloc's
13250 internal overhead when calculating the initial malloc maximum.
13252 Port --enable-checking=all to Fedora 14 x86.
13253 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13255 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13256 (overrun_check_realloc, overrun_check_free):
13257 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13258 That way, xmalloc returns a properly-aligned pointer even if
13259 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13260 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13261 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13262 into account when calculating the initial malloc maximum.
13263 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13264 Move here from alloc.c, so that charset.c can use it too.
13265 Properly align; the old code wasn't right for common 32-bit hosts
13266 when configured with --enable-checking=all.
13267 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13268 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13270 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13272 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13275 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13277 * xdisp.c (compute_display_string_end): If there's no display
13278 string at CHARPOS, return -1.
13280 * bidi.c (bidi_fetch_char): When compute_display_string_end
13281 returns a negative value, treat the character as a normal
13282 character not covered by a display string. (Bug#9624)
13284 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13286 * lread.c (Fread_from_string): Fix typo in docstring.
13288 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13290 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13291 newline, reseat the iterator instead of bidi-iterating there one
13292 character at a time. (Bug#9610)
13293 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13294 TO_CHARPOS if the bidi iterator is at base embedding level.
13296 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13298 * lread.c (readevalloop): Use correct code for NBSP.
13299 (read1): Likewise. (Bug#9608)
13301 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13303 * dbusbind.c (Fdbus_register_signal): When service is not
13304 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13306 2011-09-25 Glenn Morris <rgm@gnu.org>
13308 * buffer.c (truncate-lines): Doc fix.
13310 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13312 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13313 (Fset_window_next_buffers): Doc fix.
13315 2011-09-24 Glenn Morris <rgm@gnu.org>
13317 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13319 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13321 Fix minor problems found by static checking.
13322 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13323 * indent.c (Fvertical_motion): Fix == vs = typo.
13325 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13327 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13328 Default value is now t. Doc fix.
13330 * indent.c (Fvertical_motion): Compute and apply the overshoot
13331 logic when moving up, not only when moving down. Fix the
13332 confusing name and values of the it_overshoot_expected variable;
13333 logic changes accordingly. (Bug#9254) (Bug#9549)
13335 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13336 CHARPOS is covered by a display string which includes newlines.
13337 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13338 is covered by a display string with embedded newlines.
13340 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13342 * dbusbind.c (Fdbus_register_signal): Add match rule to
13343 Vdbus_registered_objects_table. (Bug#9581)
13344 (Fdbus_register_method, Vdbus_registered_objects_table):
13347 2011-09-24 Jim Meyering <meyering@redhat.com>
13349 do not ignore write error for any output size
13350 The previous change was incomplete.
13351 While it makes emacs --batch detect the vast majority of stdout
13352 write failures, errors were still ignored whenever the output size is
13353 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13354 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13355 && echo FAIL: ignored write error
13356 FAIL: ignored write error
13357 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13358 && echo FAIL: ignored write error
13359 FAIL: ignored write error
13360 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13362 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13364 * emacs.c (Fkill_emacs): In noninteractive mode exit
13365 non-successfully if a write error occurred on stdout. (Bug#9574)
13367 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13369 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13372 * dispextern.h (struct it): Update the comment documenting what
13375 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13377 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13378 a display string, extend search for cursor position to end of row.
13379 (find_row_edges): If the row ends in a newline from a display
13380 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13381 Handle the case of a display string with multiple newlines.
13382 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13383 non-empty line. Fixes confusing cursor motion with arrow keys at
13384 the beginning of a line that starts with whitespace.
13386 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13388 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13391 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13393 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13394 boolean (Bug#9154).
13396 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13398 * xdisp.c (display_line): Record maximum and minimum buffer
13399 positions even if no glyphs were produced (e.g., by a zero-width
13400 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13401 buffer positions that will be removed from the glyph row because
13403 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13404 column is beyond frame width: don't subtract 1 "pixel" when
13405 computing width of the stretch.
13406 (reseat_at_next_visible_line_start): Undo the change made on
13407 2011-09-17 that saved paragraph information and restored it after
13408 the call to `reseat'. (Bug#9545)
13410 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13412 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13413 and turn window cursor on if cleared (Bug#9415).
13415 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13417 * search.c (boyer_moore): Take unibyte characters from pattern
13418 literally. (Bug#9458)
13420 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13422 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13424 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13426 Fix minor problem found by static checking.
13427 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13428 initialized, to pacify gcc -Wuninitialized.
13430 * fileio.c: Report proper errno when syscall falls.
13431 (Finsert_file_contents): Save and restore errno,
13432 so that report_file_error outputs the correct diagnostic.
13433 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13435 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13437 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13439 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13441 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13442 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13444 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13446 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13447 about the current paragraph and restore it after the call to reseat.
13449 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13450 (bidi_find_paragraph_start): Search back for paragraph beginning
13451 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13452 (bidi_move_to_visually_next): Only trigger paragraph-related
13453 computations when the last character is a newline or at EOB, not
13454 just any NEUTRAL_B. (Bug#9470)
13456 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13457 truncated lines if point is covered by a display string. (Bug#9524)
13459 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13461 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13462 (cons_to_x_long): New function.
13463 (lisp_data_to_selection_data): Use it. Correct the test for
13464 short-versus-long data; it was negated. Break out of vector
13465 loop, for efficiency, when a long datum is discovered.
13467 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13469 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13471 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13473 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13474 GCC PR/17406) by declaring this function with external scope.
13476 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13478 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13479 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13481 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13483 * editfns.c (Fformat): Correctly handle text properties on "%%".
13485 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13487 * xterm.c (x_draw_composite_glyph_string_foreground):
13488 * w32term.c (x_draw_composite_glyph_string_foreground):
13489 * term.c (encode_terminal_code):
13490 * composite.c (composition_update_it, get_composition_id):
13491 * xdisp.c (get_next_display_element)
13492 (fill_composite_glyph_string): Add comments about special meaning
13493 of TAB characters in a composition.
13495 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13497 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13498 This occurs when processing a multibyte format.
13499 Problem reported by Wolfgang Jenker.
13501 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13503 * xdisp.c (try_cursor_movement): Only check for exact match if
13504 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13506 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13508 Remove unused external symbols.
13509 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13510 * xdisp.c (calc_pixel_width_or_height): Now static.
13511 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13512 * indent.c (check_display_width):
13513 * w32term.c: Fix comment to match code.
13514 * xterm.c, xterm.h (x_catching_errors): Remove.
13516 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13518 * xselect.c: Use signed conversions more consistently (Bug#9498).
13519 (selection_data_to_lisp_data): Assume incoming selection data are
13520 signed integers, not unsigned. This is to be consistent with
13521 outgoing selection data, which was modified to use signed integers
13522 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13523 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13524 expects long, not unsigned long.
13526 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13528 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13529 computation of loop end. Reported by Johan Bockgård
13532 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13534 * frame.c (Fother_visible_frames_p): Function deleted.
13536 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13538 * indent.c (compute_motion): Process display vector front to back
13539 rather than the other way around. (Bug#2496)
13541 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13543 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13545 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13547 * minibuf.c (Fread_from_minibuffer): Doc fix.
13549 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13551 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13552 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13554 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13556 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13557 value for non-existent files.
13559 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13561 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13562 set its "size" to -1. This will set the modtime_size field of
13563 the corresponding buffer to -1, which is what
13564 verify-visited-file-modtime expects for files that do not exist.
13567 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13569 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13571 * lisp.h: ... from here. push_key_description is no longer
13572 defined in keyboard.c, so its declaration should not be in
13573 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13574 logically belongs with push_key_description.
13576 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13578 * buffer.h: Include <sys/types.h> instead of <time.h>.
13579 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13580 Problem reported by Herbert J. Skuhra.
13582 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13584 * xml.c (parse_region): Make the parsing work for
13585 non-comment-starting XML files again (bug#9144).
13587 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13589 * image.c (gif_load): Fix calculation of bottom and right corner.
13592 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13594 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13595 redisplay in small windows.
13597 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13599 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13601 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13603 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13604 Operate on live windows only.
13606 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13608 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13610 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13612 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13613 only under bidi iteration.
13615 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13617 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13619 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13621 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13622 Without this fix, the command to link temacs failed due to an
13623 undefined symbol __builtin_isnan. This is because
13624 /usr/include/iso/math_c99.h #defines isnan(x) to
13625 __builtin_isnan(x), but the bundled gcc, which identifies itself
13626 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13628 * floatfns.c (isnan): #undef, and then #define to a clone of
13630 (Fisnan): Always define, since it's always available now.
13631 (syms_of_floatfns): Always define isnan at the Lisp level.
13633 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13635 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13637 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13639 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13640 The previous code assumed that file offsets (off_t values) fit in
13641 EMACS_INT variables, which is not true on typical 32-bit hosts.
13642 The code messed up by falsely reporting buffer overflow in cases
13643 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13644 when "big" contains more than 2**29 bytes, even though this
13645 inserts just one byte and does not overflow the buffer.
13646 (Finsert_file_contents): Store file offsets as off_t
13647 values, not as EMACS_INT values. Check for overflow when
13648 converting between EMACS_INT and off_t. When checking for
13649 buffer overflow or for overlap, take the offsets into account.
13650 Don't use EMACS_INT for small values where int suffices.
13651 When checking for overlap, fix a typo: ZV was used where
13652 ZV_BYTE was intended.
13653 (Fwrite_region): Don't assume off_t fits into 'long'.
13654 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13656 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13658 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13660 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13662 sprintf-related integer and memory overflow issues (Bug#9412).
13664 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13665 (esprintf, exprintf, evxprintf): New functions.
13666 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13667 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13668 (modify_event_symbol): Do not assume that the length of
13669 name_alist_or_stem is safe to alloca and fits in int.
13670 (Fexecute_extended_command): Likewise for function name and binding.
13671 (Frecursion_depth): Wrap around reliably on integer overflow.
13672 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13673 since some callers pass EMACS_INT values.
13674 (Fsingle_key_description): Don't crash if symbol name contains more
13675 than MAX_ALLOCA bytes.
13676 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13677 (get_minibuffer): Arg is now EMACS_INT, not int.
13678 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13679 (esprintf, exprintf, evxprintf): New decls.
13680 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13682 * dbusbind.c (signature_cat): New function.
13683 (xd_signature, Fdbus_register_signal):
13684 Do not overrun buffer; instead, report string overflow.
13686 * dispnew.c (add_window_display_history): Don't overrun buffer.
13687 Truncate instead; this is OK since it's just a log.
13689 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13690 even if the time zone offset is outlandishly large.
13691 Don't mishandle offset == INT_MIN.
13693 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13694 when creating daemon; the previous buffer-overflow check was incorrect.
13696 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13697 which has the guts of the old verror function.
13699 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13700 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13702 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13703 (font_unparse_xlfd): Don't blindly alloca long strings.
13704 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13705 fits in int, when using sprintf. Use single snprintf to count
13706 length of string rather than counting it via multiple sprintfs;
13707 that's simpler and more reliable.
13708 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13709 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13710 sprintf, in case result does not fit in int.
13712 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13713 (fontset_from_font): Print it.
13715 * frame.c (tty_frame_count): Now printmax_t, not int.
13716 (make_terminal_frame, set_term_frame_name): Print it.
13717 (x_report_frame_params): In X, window IDs are unsigned long,
13718 not signed long, so print them as unsigned.
13719 (validate_x_resource_name): Check for implausibly long names,
13720 and don't assume name length fits in 'int'.
13721 (x_get_resource_string): Don't blindly alloca invocation name;
13722 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13725 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13726 (xg_check_special_colors, xg_set_geometry):
13727 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13729 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13730 Use esprintf, not sprintf, in case result does not fit in int.
13732 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13733 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13734 it as a large positive number.
13735 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13736 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13738 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13739 in case result does not fit in int.
13741 * print.c (float_to_string): Detect width overflow more reliably.
13742 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13743 buffer overrun. Don't assume list length fits in 'int'. Treat
13744 print length of 0 as 0, not as infinity; to be consistent with other
13745 uses of print length in this function. Don't overflow print length
13746 index. Don't assume hash table size fits in 'long', or that
13747 vectorlike size fits in 'unsigned long'.
13749 * process.c (make_process): Use printmax_t, not int, to format
13750 process-name gensyms.
13752 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13754 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13755 to avoid potential buffer overrun.
13757 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13758 if X resource line is longer than 512 bytes.
13760 * xfns.c (x_window): Make sprintf buffer a bit bigger
13761 to avoid potential buffer overrun.
13763 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13765 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13767 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13769 Integer overflow fixes for scrolling, etc.
13770 Without these, Emacs silently mishandles large integers sometimes.
13771 For example, "C-u 4294967297 M-x recenter" was treated as if
13772 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13774 * xdisp.c (try_window_id): Check Emacs fixnum range before
13775 converting to 'int'.
13777 * window.c (window_scroll_line_based, Frecenter):
13778 Check that an Emacs fixnum is in range before assigning it to 'int'.
13779 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13780 values converted from Emacs fixnums.
13781 (Frecenter): Don't wrap around a line count if it is out of 'int'
13782 range; instead, treat it as an extreme value.
13783 (Fset_window_configuration, compare_window_configurations):
13784 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13786 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13787 that can exceed INT_MAX. Check that EMACS_INT value is in range
13788 before assigning it to the (possibly-narrower) index.
13789 (match_limit): Don't assume that a fixnum can fit in 'int'.
13791 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13794 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13795 (Fvertical_motion): Don't wrap around LINES values that don't fit
13796 in 'int'. Instead, treat them as extreme values. This is good
13797 enough for windows, which can't have more than INT_MAX lines anyway.
13799 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13801 * Require libxml/parser.h to avoid compilation warning.
13803 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13805 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13806 since this reportedly can destroy thread storage.
13808 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13810 * syntax.c (find_defun_start): Update all cache variables if
13811 exiting early (Bug#9401).
13813 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13815 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13817 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13818 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13819 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13821 * term.c (tty_append_glyph): New function.
13822 (produce_stretch_glyph): Static function and its prototype deleted.
13824 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13827 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13829 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13830 when checking :margin (Bug#9390).
13831 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13832 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13833 so that the name doesn't mislead. All uses changed.
13835 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13837 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13840 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13842 * xdisp.c (move_it_to): Don't bail out early when reaching
13843 position beyond to_charpos, if we are scanning backwards.
13844 (move_it_vertically_backward): When DY == 0, make sure we get to
13845 the first character in the line after the newline.
13847 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13849 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13850 (ccl_driver): Do not generate an out-of-range pointer.
13851 (Fccl_execute_on_string): Remove unnecessary check for
13852 integer overflow, noted by Stefan Monnier in
13853 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13854 Remove a FIXME that didn't need fixing.
13855 Simplify the newly-introduced buffer reallocation code.
13857 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13859 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13861 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13863 Integer and memory overflow issues (Bug#9196).
13865 * doc.c (get_doc_string): Rework so that
13866 get_doc_string_buffer_size is the actual buffer size, rather than
13867 being 1 less than the actual buffer size; this makes xpalloc more
13870 * image.c (x_allocate_bitmap_record, cache_image):
13871 * xselect.c (Fx_register_dnd_atom):
13872 Simplify previous changes by using xpalloc.
13874 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13875 since either will do and ptrdiff_t is convenient with xpalloc.
13877 * charset.c (charset_table_size)
13878 (struct charset_sort_data.priority): Now ptrdiff_t.
13879 (charset_compare): Don't overflow if priorities differ greatly.
13880 (Fsort_charsets): Don't assume list length fits in int.
13881 Check for size-calculation overflow when allocating sort data.
13882 (syms_of_charset): Allocate an initial charset table that is
13883 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13885 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13887 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13888 The actual value is always <= INT_MAX, and leaving it unsigned made
13889 overflow checking harder.
13891 * dispextern.h (struct glyph_matrix.rows_allocated)
13892 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13893 with xpalloc. The values are still always <= INT_MAX.
13895 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13897 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13898 (SAFE_NALLOCA): New macro.
13900 * region-cache.c (struct boundary.pos, find_cache_boundary)
13901 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13902 (set_cache_region, invalidate_region_cache)
13903 (revalidate_region_cache, know_region_cache, region_cache_forward)
13904 (region_cache_backward, pp_cache):
13905 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13906 so that ptrdiff_t * can be passed to xpalloc.
13907 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13908 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13909 (pp_cache): Don't assume cache_len fits in int.
13910 * region-cache.h: Adjust extern decls to match.
13912 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13913 EMACS_INT, since either will do, for xpalloc.
13915 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13916 (xnmalloc, xnrealloc, xpalloc): New functions.
13918 * bidi.c (bidi_shelve_header_size): New constant.
13919 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13920 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13922 * bidi.c (bidi_cache_shrink):
13923 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13925 Don't update size of array until after memory allocation succeeds,
13926 because xmalloc/xrealloc may not return.
13927 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13928 now that we have proper integer overflow checking.
13929 (record_overlay_string, overlay_strings): Catch overflows when
13930 calculating size of overlay_str_buf.
13932 * callproc.c (Fcall_process): Check for size overflow when
13933 calculating size of args2.
13934 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13935 Normally we prefer signed values, but sticking with ptrdiff_t would
13936 require adding more-complicated checks.
13938 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13939 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13940 Redo buffer-overflow calculations to avoid integer overflow.
13941 Add a FIXME comment where memory seems to be over-allocated.
13943 * character.c (Fstring): Check for size-calculation overflow.
13945 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13946 unnecessary integer overflow. Check for size overflow.
13947 (encode_coding_object): Don't update size until xmalloc succeeds.
13949 * composite.c (get_composition_id): Check for overflow in glyph
13950 length calculations.
13952 Integer and memory overflow fixes for display code.
13953 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13954 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13955 (scrolling_window): Check for overflow in size calculations.

13961 Don't update size until allocation succeeds.
13962 * fns.c (concat): Check for overflow in size calculations.
13963 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
13964 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

13967 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13968 (get_doc_string): Check for size calculation overflow.
13969 Don't update size until allocation succeeds.
13970 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13971 EMACS_INT, where ptrdiff_t will do.
13972 (Fsubstitute_command_keys): Check for string overflow.
13974 * editfns.c (set_time_zone_rule): Don't assume environment length
13976 (message_length): Now ptrdiff_t, not int.
13977 (Fmessage_box): Don't update size until allocation succeeds.
13978 Don't assume message length fits in int.
13979 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13981 * emacs.c (main): Do not reallocate argv, since there is a null at
13982 the end that can be overwritten, and this way there's no need to
13983 worry about size-calculation overflow.
13984 (sort_args): Check for size-calculation overflow.
13986 * eval.c (init_eval_once, grow_specpdl): Don't update size until
13988 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
13990 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
13991 (x_set_scroll_bar_width, x_figure_window_size):
13992 Check for integer overflow.
13993 (x_set_alpha): Do not assume XINT fits in int.
13995 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13996 This is for the members text_lines, text_cols, total_lines, total_cols,
13997 where the system imposes an 'int' limit.
13999 * fringe.c (Fdefine_fringe_bitmap):
14000 Don't update size until alloc works.
14002 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14003 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14005 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14006 Check for size-calculation overflow.
14007 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14008 do, as we prefer signed integers.
14009 (id_to_widget.max_size, id_to_widget.used)
14010 (xg_store_widget_in_map, xg_remove_widget_from_map)
14011 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14012 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14013 Use and return ptrdiff_t, not int.
14014 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14015 * gtkutil.h: Change prototypes to match the above.
14017 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14018 are duplicate now that they've been promoted to lisp.h.
14019 (x_allocate_bitmap_record, x_alloc_image_color)
14020 (make_image_cache, cache_image, xpm_load):
14021 Don't update size until alloc is done.

14032 Use ptrdiff_t, not int, to count maps.
14033 (read_char_minibuf_menu_prompt): Check for overflow in size
14034 calculations. Don't update size until allocation succeeds.
14035 Redo calculations to avoid overflow.
14036 * keyboard.h: Change prototypes to match the above.
14038 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14040 (current_minor_maps): Check for size calculation overflow.
14041 * keymap.h: Change prototypes to match the above.
14043 * lread.c (read1, init_obarray): Don't update size until alloc done.
14045 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

14048 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
14049 Now ptrdiff_t, not int.
14050 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

14062 (Fset_match_data): Don't assume list lengths fit in 'int'.
14064 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14065 for command line length. Do not attempt to address one before the
14066 beginning of an array, as that's not portable.
14068 * term.c (max_frame_lines): Remove; unused.
14069 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14071 (encode_terminal_code, calculate_costs): Check for size
14072 calculation overflow.

14078 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14079 subtracting pointers.
14080 (gobble_line): Check for overflow more carefully. Don't update size
14083 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
14084 Don't update size until alloc done.
14085 Redo size calculations to avoid overflow.
14086 Check for size calculation overflow.

14094 Use ptrdiff_t, not int, for sizes.
14095 (Finternal_make_lisp_face, cache_face):
14096 Check for size calculation overflow.
14097 (cache_face): Treat size calculation overflows as if they were
14098 memory exhaustion (the usual treatment), rather than aborting.
14100 * xfns.c (x_encode_text, x_set_name_internal)
14101 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14102 sizes, since they can exceed INT_MAX in size. Check for size
14103 calculation overflow.
14105 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14106 (xg_select): Check for size calculation overflow.
14107 Don't update size until alloc done.
14109 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14110 as sprintf is limited to int lengths.
14112 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14113 (X_LONG_MIN): New macros.
14114 Use them to make the following changes clearer.
14115 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14116 This change doesn't affect the value now, but it may help remind
14117 future maintainers not to raise the value too much later.
14118 (SELECTION_QUANTUM): Remove, replacing with ...
14119 (selection_quantum): ... new function, which avoids overflow.
14121 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14122 assumption that selection length fits in 'int'.
14123 (x_reply_selection_request, x_handle_selection_request)
14124 (x_get_window_property, receive_incremental_selection)
14125 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
14126 (lisp_data_to_selection_data, clean_local_selection_data):
14127 Use ptrdiff_t, not int, to record length of selection.
14128 (x_reply_selection_request, x_get_window_property)
14129 (receive_incremental_selection, x_property_data_to_lisp):
14130 Redo calculations to avoid overflow.
14131 (x_reply_selection_request): When sending hint, ceiling it at

14134 (x_get_window_property, receive_incremental_selection)
14135 (lisp_data_to_selection_data, x_property_data_to_lisp):
14136 Check for size-calculation overflow.
14137 (x_get_window_property, receive_incremental_selection)
14138 (lisp_data_to_selection_data, Fx_register_dnd_atom):
14139 Don't store size until memory allocation succeeds.
14140 (x_get_window_property): Plug memory leak on memory exhaustion.
14141 Don't double-block input; malloc is safe here. Don't assume 2**34
14142 - 4 fits in unsigned long. Add an xassert to check
14143 XGetWindowProperty overflow. Be more careful about overflow
14144 calculations, and distinguish size from memory overflow better.
14145 (receive_incremental_selection): When tracing, don't assume
14146 unsigned int is less than INT_MAX.
14147 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14148 harmful) conversions of unsigned short to int.
14149 (lisp_data_to_selection_data): Don't assume that integers
14150 in the range -65535 through -1 fit in an X unsigned short.
14151 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14152 result parameters unless successful. Rely on cons_to_unsigned
14153 to report problems with elements; the old code wasn't right anyway.
14154 (x_check_property_data): Check for int overflow; we cannot use
14155 a wider type due to X limits.
14156 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
14158 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
14160 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
14161 (x_term_init): Check for size calculation overflow.
14162 (x_color_cells): Don't store size until memory allocation succeeds.
14163 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
14164 Don't assume alloca size is less than MAX_ALLOCA.
14165 (x_term_init): Don't assume length fits in int (sprintf is limited
14168 Use ptrdiff_t for composition IDs.

14187 * image.c (xpm_get_color_table_h):
14188 * lisp.h (hash_lookup, hash_put):
14189 * minibuf.c (Ftest_completion):
14190 Use ptrdiff_t for hash table indexes, not int (which is too
14191 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14192 32-bit --with-wide-int hosts).
14194 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14195 Add a FIXME comment about memory leaks.
14196 (syms_of_charset): Don't assume xmalloc returns.
14198 Don't assume that stated character widths fit in int.
14199 * character.c (Fchar_width, c_string_width, lisp_string_width):
14200 * character.h (CHAR_WIDTH):
14201 * indent.c (MULTIBYTE_BYTES_WIDTH):
14202 Use sanitize_char_width to avoid undefined and/or bad behavior
14203 with outlandish widths.
14204 * character.h (sanitize_tab_width): Rename from sanitize_width,
14205 now that we have two such functions. All uses changed.
14206 (sanitize_char_width): New inline function.
14208 Don't assume that tab-width fits in int.
14209 * character.h (sanitize_width): New inline function.
14210 (SANE_TAB_WIDTH): New macro.
14211 (ASCII_CHAR_WIDTH): Use it.

14216 * fileio.c: Integer overflow issues with file modes.
14217 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
14219 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
14220 Remove unreachable code.

14223 * xterm.c: Don't go over XClientMessageEvent limit.
14224 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14225 (x_send_scroll_bar_event): Likewise. Check that the size does not
14226 exceed limits imposed by XClientMessageEvent, as well as the usual
14227 ptrdiff_t and size_t limits.
14229 * keyboard.c: Overflow, signedness and related fixes.
14230 (make_lispy_movement): Use same integer type in forward decl
14231 that is used in the definition.
14232 (read_key_sequence, keyremap_step):
14233 Change bufsize argument back to int, undoing my 2011-03-30 change.
14234 We prefer signed types, and int is wide enough here.
14235 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14236 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14237 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14238 length, not size_t. Use ptrdiff_t for index, not int.
14239 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14240 possibility of integer overflow.
14242 Overflow, signedness and related fixes for images.
14244 * dispextern.h (struct it.stack[0].u.image.image_id)
14245 (struct_it.image_id, struct image.id, struct image_cache.size)
14246 (struct image_cache.used, struct image_cache.ref_count):

14252 * xdisp.c (calc_pixel_width_or_height):
14253 * xfns.c (image_cache_refcount):
14254 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
14255 on typical 64-bit hosts.

14263 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14264 (lookup_image): Remove unnecessary tests.
14265 (xbm_image_p): Locals are now of int, not EMACS_INT,
14266 since parse_image_check makes sure they fit into int.
14267 (png_load, gif_load, svg_load_image):
14268 Prefer int to unsigned where either will do.
14269 (tiff_handler): New function, combining the cores of the
14270 old tiff_error_handler and tiff_warning_handler.
14271 This function is rewritten to use vsnprintf and thereby avoid
14272 stack buffer overflows. It uses only the features of vsnprintf
14273 that are common to both POSIX and native Microsoft.
14274 (tiff_error_handler, tiff_warning_handler): Use it.
14275 (tiff_load, gif_load, imagemagick_load_image):
14276 Don't assume :index value fits in 'int'.

14279 the integer types that MagickCropImage accepts. Don't assume
14280 Vimagemagick_render_type has a nonnegative value. Don't assume
14281 size_t fits in 'long'.

14297 `(space ...)', and specifies display in the text area, return 2
14299 (try_cursor_movement): Check for the need to scroll more
14300 accurately, and prefer exact match for point under bidi.
14301 Don't advance `row' beyond the last row of the window.

14354 * xdisp.c (redisplay_window): When computing centering_position,
14355 account for the height of the header line. (Bug#8874)
14357 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14358 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14359 candidate is selected by the mouse, and that candidate has a
14360 composed character under the mouse.
14362 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14363 coordinates reported by pos-visible-in-window-p for a composed
14364 character in column zero.

14374 composed buffer positions.
14376 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14378 * image.c (gif_load): Don't assume that each subimage has the same
14379 dimensions as the base image. Handle disposal method that is
14380 "undefined" by the gif spec (Bug#9335).

14390 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14391 from an Org mode buffer to a Speedbar frame.
14393 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14394 a composition, take its buffer position from IT->cmp_it.charpos.
14395 Fixes cursor positioning at the beginning of a line that begins
14396 with a composed character.
14398 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14400 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14401 character bidirectional type, use STRONG_L instead. Fixes crashes
14402 in a buffer produced by `describe-categories'.
14404 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14405 members before the level stack, so they would be saved and
14406 restored when copying iterator state. Fixes incorrect reordering
14407 around TABs covered by display properties.

14544 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14545 properties. (Bug#9284)

14752 accommodate underlining, etc.
14754 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14756 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14759 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14761 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14762 Without this fix, if a signal arrives just after memory fills up,
14763 'malloc' might be invoked reentrantly.
14765 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14766 In other words, assume that every image size is allowed, on non-X
14767 hosts. This assumption is probably wrong, but it lets Emacs compile.
14769 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14771 * regex.c (re_iswctype): Convert return values to boolean.
14773 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14775 * xdisp.c (compute_display_string_pos): Don't use cached display
14776 string position if the buffer had its restriction changed.
14779 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14781 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14783 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14785 Integer signedness and overflow and related fixes. (Bug#9079)
14787 * bidi.c: Integer size and overflow fixes.
14788 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14789 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14790 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14791 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14792 (bidi_find_other_level_edge):
14793 Use ptrdiff_t instead of EMACS_INT where either will do.
14794 This works better on 32-bit hosts configured --with-wide-int.
14795 (bidi_cache_ensure_space): Check for size-calculation overflow.
14796 Use % rather than repeated addition, for better worst-case speed.
14797 Don't set bidi_cache_size until after xrealloc returns, because it
14799 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14800 (bidi_cache_ensure_space): Also check that the bidi cache size
14801 does not exceed that of the largest Lisp string or buffer. See Eli
14802 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14804 * alloc.c (__malloc_size_t): Remove.
14805 All uses replaced by size_t. See Andreas Schwab's note
14806 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14808 * image.c: Improve checking for integer overflow.
14809 (check_image_size): Assume that f is nonnull, since
14810 it is always nonnull in practice. This is one less thing to
14811 worry about when checking for integer overflow later.
14812 (x_check_image_size): New function, which checks for integer
14813 overflow issues inside X.
14814 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14815 This removes the need for a memory_full check.
14816 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14817 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14818 (xbm_read_bitmap_data): Change locals back to 'int', since
14819 their values must fit in 'int'.
14820 (xpm_load_image, png_load, tiff_load):
14821 Invoke x_create_x_image_and_pixmap earlier,
14822 to avoid much needless work if the image is too large.
14823 (tiff_load): Treat overly large images as if
14824 x_create_x_image_and_pixmap failed, not as malloc failures.
14825 (gs_load): Use x_check_image_size.
14827 * gtkutil.c: Omit integer casts.
14828 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14829 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14831 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14833 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14834 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14835 would wrongly return t on a 64-bit host.
14837 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14838 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14839 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14840 and therefore cause GCC to emit a bogus diagnostic in some cases.
14842 * image.c: Integer signedness and overflow and related fixes.
14843 This is not an exhaustive set of fixes, but it's time to
14844 record what I've got.
14845 (lookup_pixel_color, check_image_size): Remove redundant decls.
14846 (check_image_size): Don't assume that arbitrary EMACS_INT values
14847 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14848 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14849 (tiff_load, imagemagick_load_image):
14850 Check for overflow in size calculations.
14851 (x_create_x_image_and_pixmap): Remove unnecessary test for
14852 xmalloc returning NULL; that can't happen.
14853 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14854 (xpm_color_bucket): Use better integer hashing function.
14855 (xpm_cache_color): Don't possibly over-allocate memory.
14856 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14857 (gif_memory_source):
14858 Use ptrdiff_t, not int or size_t, to record sizes.
14859 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14860 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14861 either works, as we prefer signed integers.
14862 (tiff_read_from_memory, tiff_write_from_memory):
14863 Return tsize_t, not size_t, since that's what the TIFF API wants.
14864 (tiff_read_from_memory): Don't fail simply because the read would
14865 go past EOF; instead, return a short read.
14866 (tiff_load): Omit no-longer-needed casts.
14867 (Fimagemagick_types): Don't assume size fits into 'int'.
14869 Improve hashing quality when configured --with-wide-int.
14870 * fns.c (hash_string): New function, taken from sxhash_string.
14871 Do not discard information about ASCII character case; this
14872 discarding is no longer needed.
14873 (sxhash-string): Use it. Change sig to match it. Caller changed.
14874 * lisp.h: Declare it.
14875 * lread.c (hash_string): Remove, since we now use fns.c's version.
14876 The fns.c version returns a wider integer if --with-wide-int is
14877 specified, so this should help the quality of the hashing a bit.
14879 * emacs.c: Integer overflow minor fix.
14880 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14881 Define only if GNU_LINUX.
14882 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14884 * dispnew.c: Integer signedness and overflow fixes.
14885 Remove unnecessary forward decls, that were a maintenance hassle.
14886 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14888 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14889 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14890 (prepare_desired_row, line_draw_cost):
14891 Use int, not unsigned, where either works.
14892 (save_current_matrix, restore_current_matrix):
14893 Use ptrdiff_t, not size_t, where either works.
14894 (init_display): Check for overflow more accurately, and without
14895 relying on undefined behavior.
14897 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14898 Remove, replacing with the new symbols in lisp.h. All uses changed.
14899 * fileio.c (make_temp_name):
14900 * filelock.c (lock_file_1, lock_file):
14901 * xdisp.c (message_dolog):
14902 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14903 Use pMd etc. instead.
14904 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14905 replacing the pWIDE etc. symbols removed from editfns.c.
14907 * keyboard.h (num_input_events): Now uintmax_t.
14908 This is (very slightly) less likely to mess up due to wraparound.
14911 * buffer.c: Integer signedness fixes.
14912 (alloc_buffer_text, enlarge_buffer_text):
14913 Use ptrdiff_t rather than size_t when either will do, as we prefer
14916 * alloc.c: Integer signedness and overflow fixes.
14917 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14918 (__malloc_size_t): Default to size_t, not to int.
14919 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14920 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14921 Prefer ptrdiff_t to size_t when either would do, as we prefer
14923 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14924 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14925 Now const. Initialize with values that are in range even if char
14927 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14928 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14929 These functions do the right thing with sizes > 2**32.
14930 (check_depth): Now ptrdiff_t, not int.
14931 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14932 Adjust to new way of storing sizes. Check for size overflow bugs
14934 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14935 slightly wrong anyway, as it missed one instance of
14936 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14937 (refill_memory_reserve): Omit needless cast to size_t.
14938 (mark_object_loop_halt): Mark as externally visible.
14940 * xselect.c: Integer signedness and overflow fixes.
14941 (Fx_register_dnd_atom, x_handle_dnd_message):
14942 Use ptrdiff_t, not size_t, since we prefer signed.
14943 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14944 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14945 x_dnd_atoms_size and x_dnd_atoms_length.
14947 * doprnt.c: Prefer signed to unsigned when either works.
14949 * doprnt.c (doprnt):
14951 * xdisp.c (vmessage):
14952 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14953 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14954 prefer signed arithmetic to avoid comparison confusion.
14955 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14956 but is a bit tricky.
14958 Assume freestanding C89 headers, string.h, stdlib.h.
14959 * data.c, doprnt.c, floatfns.c, print.c:
14960 Include float.h unconditionally.
14961 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14962 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14963 * regex.c: Likewise for stddef.h, string.h.
14964 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14965 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14966 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14967 (STDC_HEADERS): Remove obsolete defines.
14968 * sysdep.c: Include limits.h unconditionally.
14970 Assume support for memcmp, memcpy, memmove, memset.
14971 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14972 * regex.c (memcmp, memcpy):
14973 Remove; we assume C89 now.
14975 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14976 (__malloc_safe_bcopy): Remove; no longer needed.
14978 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14979 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14980 well either way, and we prefer signed to unsigned.
14982 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14984 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14985 closes the connection while we're reading (bug#9182).
14987 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14989 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14990 are specified (Bug#9168).
14992 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14994 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14995 Found by GCC static checking and --with-wide-int on a 32-bit host.
14997 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14999 * xdisp.c (compute_display_string_pos): Fix logic of caching
15000 previous display string position. Initialize cached_prev_pos to
15001 -1. Fixes slow-down at the beginning of a buffer.
15003 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15005 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15006 for attrs[LFACE_FONTSET_INDEX].
15008 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15010 * xml.c (parse_region): Remove unused local
15011 that was recently introduced.
15013 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15015 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15016 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15018 * xdisp.c (move_it_in_display_line_to): Record the best matching
15019 position for TO_CHARPOS while scanning the line, and restore it on
15020 exit if none of the characters scanned was an exact match.
15021 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15022 when exact match is impossible due to invisible text, and the
15023 lines are truncated.
15025 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15027 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15030 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15032 Fix a significant slow-down of cursor motion with C-n, C-p,
15033 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15034 auto-repeat under bidi redisplay in fontified buffers.
15035 * xdisp.c (compute_stop_pos_backwards): New function.
15036 (next_element_from_buffer): Call compute_stop_pos_backwards to
15037 find a suitable prev_stop when we find ourselves before
15039 (reseat): Don't look for prev_stop, as that could mean a very long
15041 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15042 <cached_disp_overlay_modiff>: Cache for last found display string
15044 (compute_display_string_pos): Return the cached position if asked
15045 about the same buffer in the same area of character positions, and
15046 the buffer wasn't changed since the time the display string
15047 position was cached.
15049 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15051 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15052 is an integer, which is important for empty lines. (Bug#9149)
15054 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15056 * frame.c (Fmodify_frame_parameters): In tty case, update the
15057 default face if necessary (Bug#4238).
15059 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15061 * editfns.c (Fstring_to_char): No need to explain what a character
15062 is in the docstring (Bug#6576).
15064 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15066 * xml.c (parse_region): Make sure we always return a tree.
15068 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15070 * xml.c (parse_region): If a document contains only comments,
15073 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15075 * xml.c (make_dom): Return comments, too.
15077 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15080 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15081 and the surrounding thread.
15082 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15083 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15084 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15086 * s/openbsd.h (BROKEN_SIGIO): Define.
15087 * unexelf.c (unexec) [__OpenBSD__]:
15088 Don't update the .mdebug section of the Alpha COFF symbol table.
15090 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15092 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15095 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15097 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15098 This fixes some race conditions on the permissions of any newly
15101 * alloc.c (valid_pointer_p): Use pipe, not open.
15102 This fixes some permissions issues when debugging.
15104 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15105 If fchown fails to set both uid and gid, try to set just gid,
15106 as that is sometimes allowed. Adjust the file's mode to eliminate
15107 setuid or setgid bits that are inappropriate if fchown fails.
15109 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15111 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15112 to compare Lisp_Objects.
15113 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15114 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15115 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15117 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15119 * lread.c (read_integer): Unread even EOF character.
15120 (read1): Likewise. Properly record start position of symbol.
15122 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15123 symbol character follows.
15125 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15127 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15128 This works around a problem with the previous change to Fcopy_file.
15129 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15130 and without this change, GCC might complain about discarding
15131 fchown's return value.
15133 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15135 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15137 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15139 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15141 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15143 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15144 it's used from the C level.
15146 * process.c: Use the same condition for POLL_FOR_INPUT in both
15147 keyboard.c and process.c (bug#1858).
15149 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15151 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15152 (Fgnutls_boot): Use it.
15154 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15156 * doc.c (Fsubstitute_command_keys): Revert last change.
15158 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15160 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15161 quotes the next character, and doesn't affect other longer
15162 sequences (bug#8935).
15164 * lread.c (syms_of_lread): Clarify that is isn't only
15165 `eval-buffer' and `eval-defun' that's affected by
15166 `lexical-binding' (bug#8460).
15168 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15170 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15171 bidi redisplay when a line includes both an image and is truncated.
15173 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15175 Fix minor problems found by static checking.
15176 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15177 (elsz): Now a signed constant, not a size_t var. We prefer signed
15178 types to unsigned, to avoid integer comparison confusion. Without
15179 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15180 "cannot optimize loop, the loop counter may overflow", a symptom
15182 * indent.c (Fvertical_motion): Mark locals as initialized.
15183 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15185 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15187 * search.c (Fre_search_backward): Mention `case-fold-search' in
15188 all the re_search_* functions (bug#8138).
15190 * keyboard.c (Fopen_dribble_file): Document when the file is
15193 2011-07-14 Eli Zaretskii <eliz@gnu.org>

15711 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

15748 Random fixes. E.g., (random) never returned negative values.
15749 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15750 subseconds part to the entropy, as that's a bit more random.
15751 Prefer signed to unsigned, since the signedness doesn't matter and
15752 in general we prefer signed. When given a limit, use a
15753 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15754 latter isn't right if USE_2_TAGS_FOR_INTS.
15755 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15756 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15768 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15769 This is more efficient than Ffile_directory_p and avoids a minor race.

15773 * buffer.c (Foverlay_put): Say what the return value is
15776 * fileio.c (barf_or_query_if_file_exists): Check first if the file

15780 error be more correct.
15782 * fns.c (Frequire): Remove the mention of the .gz files, since

15796 Qgnutls_bootprop_verify_error (which is no longer used).
15798 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15799 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15800 Also (re)move comments that are misplaced or no longer relevant.

15901 * eval.c (struct backtrace): Simplify and port the data structure.
15902 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15903 signed bit field, as this assumption is not portable and it makes
15904 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15905 "char debug_on_exit : 1" as this is not portable either; instead,
15906 use the portable "unsigned int debug_on_exit : 1". Remove unused
15907 member evalargs. Remove obsolete comments about cc bombing out.
15909 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16071 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16073 Integer and buffer overflow fixes (Bug#8873).
16075 * print.c (printchar, strout): Check for string overflow.
16076 (PRINTPREPARE, printchar, strout):
16077 Don't set size unless allocation succeeds.
16079 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16080 for sizes. Check for string overflow more accurately.
16081 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16083 * macros.c: Integer and buffer overflow fixes.
16084 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16085 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16086 Use ptrdiff_t, not int, for sizes.
16087 Don't increment bufsize until after realloc succeeds.
16088 Check for size-calculation overflow.
16089 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16091 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16093 * lread.c: Integer overflow fixes.
16094 (read_integer): Radix is now EMACS_INT, not int,
16095 to improve quality of diagnostics for out-of-range radices.
16096 Calculate buffer size correctly for out-of-range radices.
16097 (read1): Check for integer overflow in radices, and in
16098 read-circle numbers.
16099 (read_escape): Avoid int overflow.
16100 (Fload, openp, read_buffer_size, read1)
16101 (substitute_object_recurse, read_vector, read_list, map_obarray):
16102 Use ptrdiff_t, not int, for sizes.
16103 (read1): Use EMACS_INT, not int, for sizes.
16104 Check for size overflow.
16106 * image.c (cache_image): Check for size arithmetic overflow.
16108 * lread.c: Integer overflow issues.
16109 (saved_doc_string_size, saved_doc_string_length)
16110 (prev_saved_doc_string_size, prev_saved_doc_string_length):
16111 Now ptrdiff_t, not int.
16112 (read1): Don't assume doc string length fits in int. Check for
16113 out-of-range doc string lengths.
16114 (read_list): Don't assume file position fits in int.
16115 (read_escape): Check for hex character overflow.
16117 2011-06-22 Leo Liu <sdl.web@gmail.com>
16119 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16120 Move to minibuffer.el.
16122 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16124 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16125 The following patches are for when GLYPH_DEBUG && !XASSERT.
16126 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16127 * dispnew.c (flush_stdout):
16128 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16129 Mark as externally visible.
16130 * dispnew.c (check_window_matrix_pointers): Now static.
16131 * dispnew.c (window_to_frame_vpos):
16132 * xfns.c (unwind_create_frame):
16133 * xterm.c (x_check_font): Remove unused local.
16134 * scroll.c (CHECK_BOUNDS):
16135 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16136 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16137 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16138 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16139 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16141 (debug_method_add): Use va_list and vsprintf rather than relying
16142 on undefined behavior with wrong number of arguments.
16143 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16144 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16145 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16146 since we're not interested in debugging glyphs with old libraries.
16147 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16148 GCC 4.6.0's static checking.
16150 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16152 Integer overflow and signedness fixes (Bug#8873).

16160 (x_create_bitmap_from_data, x_create_bitmap_from_file)
16161 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16162 (x_create_bitmap_from_xpm_data):
16163 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16164 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16166 * xfaces.c (load_pixmap):
16167 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16168 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16169 (.bitmaps_last, struct x_output.icon_bitmap):
16170 Use ptrdiff_t, not int, for bitmap indexes.
16171 (x_allocate_bitmap_record): Check for size overflow.
16172 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16174 Use ptrdiff_t, not int, for overlay counts.
16175 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16176 * editfns.c (overlays_around, get_pos_property):
16177 * textprop.c (get_char_property_and_overlay):
16178 * xdisp.c (next_overlay_change, note_mouse_highlight):
16179 * xfaces.c (face_at_buffer_position):
16180 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16181 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16182 (Fnext_overlay_change, Fprevious_overlay_change)
16183 (mouse_face_overlay_overlaps, Foverlays_in):
16184 Use ptrdiff_t, not int, for sizes.
16185 (overlays_at, overlays_in): Check for size-calculation overflow.
16187 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16189 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16190 (x_session_initialize): Do not assume string length fits in int.
16192 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16193 This is unlikely, but can occur if DPI is outlandish.
16195 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16196 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16198 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16199 * xrdb.c (magic_file_p, search_magic_path):
16200 Omit last arg SUFFIX; it was always 0. All callers changed.
16201 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16203 * xfont.c (xfont_match): Avoid need for strlen.
16205 * xfns.c: Don't assume strlen fits in int.
16206 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16208 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16209 not unsigned long, as we prefer signed integers. All callers changed.
16210 Detect integer overflow in repeat count.
16211 (message_dolog): Don't assume print length fits in 39 bytes.
16212 (display_mode_element): Don't assume strlen fits in int.
16214 * termcap.c: Don't assume sizes fit in int and never overflow.
16215 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16216 (gobble_line): Check for size-calculation overflow.
16218 * minibuf.c (Fread_buffer):
16219 * lread.c (intern, intern_c_string):
16220 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16221 Don't assume string length fits in int.
16223 * keyboard.c (parse_tool_bar_item):
16224 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16226 * font.c: Don't assume string length fits in int.
16227 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16228 Use ptrdiff_t, not int.
16229 (font_intern_prop): Don't assume string length fits in int.
16230 Don't assume integer property fits in fixnum.
16231 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16233 * filelock.c: Fix some buffer overrun and integer overflow issues.
16234 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16235 Reformulate so as not to need the command string.
16236 Invoke gzip -cd rather than gunzip, as it's more portable.
16237 (lock_info_type, lock_file_1, lock_file):
16238 Don't assume pid_t and time_t fit in unsigned long.
16239 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16240 (current_lock_owner): Prefer signed type for sizes.
16241 Use memcpy, not strncpy, where memcpy is what is really wanted.
16242 Don't assume (via atoi) that time_t and pid_t fit in int.
16243 Check for time_t and/or pid_t out of range, e.g., via a network share.
16244 Don't alloca where an auto var works fine.
16246 * fileio.c: Fix some integer overflow issues.
16247 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16248 Don't assume string length fits in int.
16249 (directory_file_name): Don't assume string length fits in long.
16250 (make_temp_name): Don't assume pid fits in int, or that its print
16251 length is less than 20.
16253 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16255 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16257 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16259 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16260 We prefer signed integers, even for size calculations.
16262 * emacs.c: Don't assume string length fits in 'int'.
16263 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16264 (main): Don't invoke strlen when not needed.
16266 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16267 (XD_DEBUG_MESSAGE): Don't waste a byte.
16269 * callproc.c (getenv_internal_1, getenv_internal)
16270 (Fgetenv_internal):
16271 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16273 * lread.c (invalid_syntax): Omit length argument.
16274 All uses changed. This doesn't fix a bug, but it simplifies the
16275 code away from its former Hollerith-constant appearance, and it's
16276 one less 'int' to worry about when looking at integer-overflow issues.
16277 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16279 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16280 This didn't break anything, but it didn't help either.
16281 It's confusing to put a bogus integer in a place where the actual
16282 value does not matter.
16283 (LIST_END_P): Remove unused macro and its bogus comment.
16284 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16286 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16287 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16289 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16290 We prefer signed types, and the value cannot exceed the EMACS_INT
16291 range anyway (because otherwise the length would not be representable).
16292 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16293 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16294 This avoids a GCC warning when WIDE_EMACS_INT.
16296 * indent.c (sane_tab_width): New function.
16297 (current_column, scan_for_column, Findent_to, position_indentation)
16298 (compute_motion): Use it. This is just for clarity.
16299 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16301 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16303 * lisp.h (lint_assume): New macro.
16304 * composite.c (composition_gstring_put_cache):
16305 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16307 * editfns.c, insdel.c:
16308 Omit unnecessary forward decls, to simplify future changes.
16310 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16312 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16314 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16315 Use much-faster test for byte-length change.
16316 Don't assume string byte-length fits in 'int'.
16317 Check that character arg fits in 'int'.
16318 (mapcar1): Declare byte as byte, for clarity.
16320 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16322 * fns.c (concat): Catch string overflow earlier.
16323 Do not rely on integer wraparound.
16325 * dispextern.h (struct it.overlay_strings_charpos)
16326 (struct it.selective): Now EMACS_INT, not int.
16327 * xdisp.c (forward_to_next_line_start)
16328 (back_to_previous_visible_line_start)
16329 (reseat_at_next_visible_line_start, next_element_from_buffer):
16330 Don't arbitrarily truncate the value of 'selective' to int.
16332 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16334 * composite.c: Don't truncate sizes to 'int'.
16335 (composition_gstring_p, composition_reseat_it)
16336 (composition_adjust_point): Use EMACS_INT, not int.
16337 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16338 not EMACS_UINT, for indexes.
16340 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16342 * buffer.c: Include <verify.h>.
16343 (struct sortvec.priority, struct sortstr.priority):
16344 Now EMACS_INT, not int.
16345 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16346 (struct sortstr.size, record_overlay_string)
16347 (struct sortstrlist.size, struct sortlist.used):
16348 Don't truncate size to int.
16349 (record_overlay_string): Check for size-calculation overflow.
16350 (init_buffer_once): Check at compile-time, not run-time.
16352 2011-06-22 Jim Meyering <meyering@redhat.com>
16354 Don't leak an XBM-image-sized buffer
16355 * image.c (xbm_load): Free the image buffer after using it.
16357 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16360 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16361 that Sun C diagnosed.
16362 * fns.c (secure_hash): Fix pointer signedness issue.
16363 * intervals.c (static_offset_intervals): New function.
16364 (offset_intervals): Use it.
16366 2011-06-21 Leo Liu <sdl.web@gmail.com>
16369 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16372 * fns.c (secure_hash): Rename from crypto_hash_function and change
16373 the first arg to accept symbols.
16374 (Fsecure_hash): New primitive.
16375 (syms_of_fns): New symbols.
16377 2011-06-20 Deniz Dogan <deniz@dogan.se>
16379 * process.c (Fset_process_buffer): Clarify return value in
16382 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16384 * dispnew.c (add_window_display_history): Use BVAR.
16386 * xdisp.c (debug_method_add): Use BVAR.
16387 (check_window_end, dump_glyph_matrix, dump_glyph)
16388 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16390 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16393 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16394 check till after the cache is created in init_frame_faces.
16396 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16398 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16400 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16402 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16403 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16404 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16406 Improve buffer-overflow checking (Bug#8873).
16407 * fileio.c (Finsert_file_contents):
16408 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16409 Remove the old (too-loose) buffer overflow checks.
16410 They weren't needed, since make_gap checks for buffer overflow.
16411 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16412 The old code merely checked for Emacs fixnum overflow, and relied
16413 on undefined (wraparound) behavior. The new code avoids undefined
16414 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16416 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16417 Tune. Don't use wider integers than needed. Don't use alloca.
16418 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16420 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16422 * insdel.c, lisp.h (buffer_overflow): New function.
16423 (insert_from_buffer_1, replace_range, replace_range_2):
16424 * insdel.c (make_gap_larger):
16425 * editfns.c (Finsert_char):
16426 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16428 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16430 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16432 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16434 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16435 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16437 * fileio.c: Don't assume EMACS_INT fits in off_t.
16438 (emacs_lseek): New static function.
16439 (Finsert_file_contents, Fwrite_region): Use it.
16440 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16442 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16444 * fns.c: Don't overflow int when computing a list length.
16445 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16446 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16447 truncation on 64-bit hosts. Check for QUIT every
16448 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16449 faster and is responsive enough.
16450 (Flength): Report an error instead of overflowing an integer.
16451 (Fsafe_length): Return a float if the value is not representable
16452 as a fixnum. This shouldn't happen except in contrived situations.
16453 (Fnthcdr, Fsort): Don't assume list length fits in int.
16454 (Fcopy_sequence): Don't assume vector length fits in int.
16456 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16457 (header_size, word_size): New constants.
16458 (allocate_vectorlike): Don't check size overflow here.
16459 (allocate_vector): Check it here instead, since this is the only
16460 caller of allocate_vectorlike that could cause overflow.
16461 Check that the new vector's length is representable as a fixnum.
16463 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16464 The previous code was bogus. For example, next_almost_prime (32)
16465 returned 39, which is undesirable as it is a multiple of 3; and
16466 next_almost_prime (24) returned 25, which is a multiple of 5 so
16467 why was the code bothering to check for multiples of 7?
16469 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16471 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16473 Variadic C functions now count arguments with ptrdiff_t.
16474 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16475 Back then I didn't know that the Emacs coding style prefers signed int.
16476 Also, in the meantime I found a few more instances where arguments
16477 were being counted with int, which may truncate counts on 64-bit
16478 machines, or EMACS_INT, which may be unnecessarily wide.
16479 * lisp.h (struct Lisp_Subr.function.aMANY)
16480 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16481 Arg counts are now ptrdiff_t, not size_t.
16482 All variadic functions and their callers changed accordingly.
16483 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16484 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16485 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16486 * callint.c (Fcall_interactively): Check arg count for overflow,
16487 to avoid potential buffer overrun. Use signed char, not 'int',
16488 for 'varies' array, so that we needn't bother to check its size
16489 calculation for overflow.
16490 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16491 * eval.c (apply_lambda):
16492 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16493 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16494 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16496 * callint.c (Fcall_interactively): Don't use index var as event count.
16498 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16499 * mem-limits.h (SIZE): Remove; no longer used.
16501 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16503 Remove unnecessary casts.
16504 * xterm.c (x_term_init):
16505 * xfns.c (x_set_border_pixel):
16506 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16507 These aren't needed now that we assume ANSI C.
16509 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16510 It's more likely to cause problems (due to unsigned overflow)
16513 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16515 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16517 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16519 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16521 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16523 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16525 GLYPH_CODE_FACE returns EMACS_INT, not int.
16526 * dispextern.h (merge_faces):
16527 * xfaces.c (merge_faces):
16528 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16529 Don't assume EMACS_INT fits in int.
16531 * character.h (CHAR_VALID_P): Remove unused parameter.
16532 * fontset.c, lisp.h, xdisp.c: All uses changed.
16534 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16536 * fns.c (concat): Minor tuning based on overflow analysis.
16537 This doesn't fix any bugs. Use int to hold character, instead
16538 of constantly refetching from Emacs object. Use XFASTINT, not
16539 XINT, for value known to be a character. Don't bother comparing
16540 a single byte to 0400, as it's always less.
16542 * floatfns.c (Fexpt):
16543 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16545 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16548 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16550 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16551 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16552 incorrectly succeed when S was a string, because 4294967386 was
16553 truncated before it was used.
16555 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16556 Otherwise, an out-of-range integer could cause undefined behavior
16559 * composite.c: Use int, not EMACS_INT, for characters.
16560 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16561 EMACS_INT, for values that are known to be in character range.
16562 This doesn't fix any bugs but is the usual style inside Emacs and
16563 may generate better code on 32-bit machines.
16565 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16566 This is for reasons similar to the recent CHAR_STRING fix.
16567 * charset.c (Fencode_char): Check that character arg is actually
16568 a character. Pass an int to ENCODE_CHAR.
16569 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16570 wider than 'int', as a compile-time check to prevent future regressions
16573 * character.c (char_string): Remove unnecessary casts.
16575 Make sure a 64-bit char is never passed to CHAR_STRING.
16576 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16577 by silently ignoring the top 32 bits, allowing some values
16578 that were far too large to be valid characters.
16579 * character.h: Include <verify.h>.
16580 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16581 arguments are no wider than unsigned, as a compile-time check
16582 to prevent future regressions in this area.
16584 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16585 (Fsubst_char_in_region):
16587 * xdisp.c (decode_mode_spec_coding):
16588 Adjust to CHAR_STRING's new requirement.
16589 * editfns.c (Finsert_char, Fsubst_char_in_region):
16590 * fns.c (concat): Check that character args are actually
16591 characters. Without this test, these functions did the wrong
16592 thing with wildly out-of-range values on 64-bit hosts.
16594 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16595 These casts should not be needed on 32-bit hosts, either.
16596 * keyboard.c (read_char):
16597 * lread.c (Fload): Remove casts to unsigned.
16599 * lisp.h (UNSIGNED_CMP): New macro.
16600 This fixes comparison bugs on 64-bit hosts.
16601 (ASCII_CHAR_P): Use it.
16602 * casefiddle.c (casify_object):
16603 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16604 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16605 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16606 * dispextern.h (FACE_FROM_ID):
16607 * keyboard.c (read_char): Use UNSIGNED_CMP.
16609 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16610 not to EMACS_INT, to avoid GCC warning.
16612 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16614 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16615 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16616 isn't needed on 32-bit machines.
16618 * buffer.c (Fgenerate_new_buffer_name):
16619 Use EMACS_INT for count, not int.
16620 (advance_to_char_boundary): Return EMACS_INT, not int.
16622 * data.c (Qcompiled_function): Now static.
16624 * window.c (window_body_lines): Now static.
16626 * image.c (gif_load): Rename local to avoid shadowing.
16628 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16629 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16630 * alloc.c (make_save_value): Integer argument is now of type
16631 ptrdiff_t, not int.
16632 (mark_object): Use ptrdiff_t, not int.
16633 * lisp.h (pD): New macro.
16634 * print.c (print_object): Use it.
16636 * alloc.c: Use EMACS_INT, not int, to count objects.
16637 (total_conses, total_markers, total_symbols, total_vector_size)
16638 (total_free_conses, total_free_markers, total_free_symbols)
16639 (total_free_floats, total_floats, total_free_intervals)
16640 (total_intervals, total_strings, total_free_strings):
16641 Now EMACS_INT, not int. All uses changed.
16642 (Fgarbage_collect): Compute overall total using a double, so that
16643 integer overflow is less likely to be a problem. Check for overflow
16644 when converting back to an integer.
16645 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16646 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16647 These were 'int' variables that could overflow on 64-bit hosts;
16648 they were never used, so remove them instead of repairing them.
16649 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16650 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16651 Previously, this ceilinged at INT_MAX, but that doesn't work on
16653 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16655 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16656 (allocate_vectorlike): Check for ptrdiff_t overflow.
16657 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16658 when a (possibly-narrower) signed value would do just as well.
16659 We prefer using signed arithmetic, to avoid comparison confusion.
16661 * alloc.c: Catch some string size overflows that we were missing.
16662 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16663 for convenience in STRING_BYTES_MAX.
16664 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16665 The definition here is exact; the one in lisp.h was approximate.
16666 (allocate_string_data): Check for string overflow. This catches
16667 some instances we weren't catching before. Also, it catches
16668 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16669 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16670 and ptrdiff_t and EMACS_INT are both 64 bits.
16672 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16673 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16674 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16676 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16678 * alloc.c (Fmake_string): Check for out-of-range init.
16680 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16682 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16684 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16686 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16687 xg_get_default_scrollbar_width.
16689 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16690 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16691 (style_changed_cb): Call update_theme_scrollbar_width and call
16692 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16693 all frames (Bug#8505).
16694 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16695 Call gtk_window_set_resizable if HAVE_GTK3.
16696 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16697 and height if HAVE_GTK3 (Bug#8505).
16698 (scroll_bar_width_for_theme): New variable.
16699 (update_theme_scrollbar_width): New function.
16700 (xg_get_default_scrollbar_width): Move code to
16701 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16702 (xg_initialize): Call update_theme_scrollbar_width.
16704 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16706 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16708 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16710 * frame.c (make_frame): Call other_buffer_safely instead of
16713 * window.c (temp_output_buffer_show): Call display_buffer with
16714 second argument Vtemp_buffer_show_specifiers and reset latter
16715 immediately after the call.
16716 (Vtemp_buffer_show_specifiers): New variable.
16717 (auto_window_vscroll_p, next_screen_context_lines)
16718 (Vscroll_preserve_screen_position): Remove leading asterisks from

16764 (Fset_window_configuration): Rewrite to handle dead buffers and
16765 consequently deletable windows.
16766 (window_tree, Fwindow_tree): Remove. Supply functionality in

16899 window_min_size_1, window_min_size_2, window_min_size,
16900 size_window, window_fixed_size_p, enlarge_window, delete_window.
16901 Remove static from declaration of Qdelete_window, it's
16902 temporarily needed by Fbury_buffer.
16903 (replace_window): Don't assign orig_top_line and
16905 (Fdelete_window, delete_window): Remove. Window deletion is

16907 (window_loop): Remove DELETE_OTHER_WINDOWS case.
16908 Replace Fdelete_window calls with calls to Qdelete_window.
16909 (Fdelete_other_windows): Remove. Deleting other windows is

17251 instead of using explicit *_CHAR codes.
17252 (bidi_resolve_explicit, bidi_resolve_weak):

17269 (display_prop_intangible_p): Reimplement to call
17270 handle_display_spec instead of single_display_spec_intangible_p.

17281 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17282 value of a `display' property is a "replacing spec".
17283 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17284 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

17312 All callers changed. (Bug#8762)
17314 * gnutls.c: Use Emacs's memory allocators.
17315 Without this change, the gnutls library would invoke malloc etc.
17316 directly, which causes problems on non-SYNC_INPUT hosts, and which
17317 runs afoul of improving memory_full behavior. (Bug#8761)
17318 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17319 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17320 xfree instead of the default malloc, realloc, free.
17321 (Fgnutls_boot): No need to check for memory allocation failure,
17322 since xmalloc does that for us.

17346 * alloc.c (allocate_vectorlike):
17347 Check for overflow in vector size calculations.
17348 * ccl.c (ccl_driver):
17349 Check for overflow when converting EMACS_INT to int.

17351 need to be updated by these changes.
17352 * fns.c (make_hash_table, maybe_resize_hash_table):
17353 Check for integer overflow with large hash tables.
17354 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17355 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17356 (SXHASH_REDUCE): New macro.
17357 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17358 Use it instead of discarding useful hash info with large hash values.
17359 (sxhash_float): New function.
17360 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17361 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17362 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17363 Rewrite to use FIXNUM_BITS, as this simplifies things.
17364 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17365 Adjust signatures to match updated version of code.
17366 (consing_since_gc): Now EMACS_INT, since a single hash table can
17367 use more than INT_MAX bytes.
17369 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17371 Make it possible to build with GCC-4.6+ -O2 -flto.
17373 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17375 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17377 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17378 Call minibuffer-inactive-mode.
17380 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17382 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17383 Update dependencies.
17385 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17387 * data.c (init_data): Remove code for UTS, this system is not
17390 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17392 Don't force ./temacs to start in terminal mode.
17394 * frame.c (make_initial_frame): Initialize faces in all cases, not
17395 only when CANNOT_DUMP is defined.
17396 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17398 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17400 * dispnew.c (add_window_display_history): Use const for the string
17401 pointer. Remove declaration, not needed.
17403 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17405 Use 'inline', not 'INLINE'.
17406 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17407 * alloc.c, fontset.c (INLINE): Remove.
17408 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17409 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17410 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17411 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17412 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17414 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17416 Make it possible to run ./temacs.
17418 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17419 syms_of_callproc does the same thing. Remove test for
17420 "initialized", do it in the caller.
17421 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17423 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17425 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17426 (read_minibuf): Use get_minibuffer.
17427 (syms_of_minibuf): Use DEFSYM.
17428 (Qmetadata): New var.
17429 * data.c (Qbuffer): Don't make it static.
17430 (syms_of_data): Use DEFSYM.
17432 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17434 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17435 (CCL_CODE_MIN): New macro.
17437 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17439 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17441 * eval.c (Qdebug): Now static.
17442 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17443 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17444 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17446 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17448 * image.c: Various fixes to ImageMagick code comments.
17449 (Fimagemagick_types): Doc fix.
17451 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17453 Minor fixes prompted by GCC 4.6.0 warnings.
17455 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17457 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17458 (x_clipboard_manager_save_all): Move extern decl to ...
17459 * xterm.h: ... here, so that it can be checked for consistency.
17461 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17463 * xselect.c (x_clipboard_manager_save_frame)
17464 (x_clipboard_manager_save_all): New functions.
17465 (Fx_clipboard_manager_save): Lisp function deleted.
17467 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17468 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17470 * xterm.h: Update prototype.
17472 2011-05-28 William Xu <william.xwl@gmail.com>
17474 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17475 exiting (Bug#8239).
17477 2011-05-28 Jim Meyering <meyering@redhat.com>
17479 Avoid a sign-extension bug in crypto_hash_function.
17480 * fns.c (to_uchar): Define.
17481 (crypto_hash_function): Use it to convert some newly-signed
17482 variables to unsigned, to avoid sign-extension bugs. For example,
17483 without this change, (md5 "truc") would evaluate to
17484 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17485 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17486 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17488 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17490 Integer overflow fixes.
17492 * dbusbind.c: Serial number integer overflow fixes.
17493 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17494 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17495 to hold a serial number that is too large for a fixnum.
17496 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17497 Check for serial numbers out of range. Decode any serial number
17498 that was so large that it became a float. (Bug#8722)
17500 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17501 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17502 Use XFASTINT rather than XUINT when numbers are nonnegative.
17503 (xd_append_arg, Fdbus_method_return_internal):
17504 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17505 arguments, check that Lisp number is nonnegative, rather than
17506 silently wrapping negative numbers around. (Bug#8722)
17507 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17510 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17512 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17514 ccl: Add integer overflow checks.
17515 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17516 (IN_INT_RANGE): New macros.
17517 (ccl_driver): Use them to check for integer overflow when
17518 decoding a CCL program. Many of the new checks are whether XINT (x)
17519 fits in int; it doesn't always, on 64-bit hosts. The new version
17520 doesn't catch all possible integer overflows, but it's an
17521 improvement. (Bug#8719)
17523 * alloc.c (make_event_array): Use XINT, not XUINT.
17524 There's no need for unsigned here.
17526 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17527 This follows up to the 2011-05-06 change that substituted uintptr_t
17528 for EMACS_INT. This case wasn't caught back then.
17530 Rework Fformat to avoid integer overflow issues.
17531 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17532 now (part of C89). Include <verify.h>.
17533 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17534 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17535 (Fformat): Avoid the prepass trying to compute sizes; it was only
17536 approximate and thus did not catch overflow reliably. Instead, walk
17537 through the format just once, formatting and computing sizes as we go,
17538 checking for integer overflow at every step, and allocating a larger
17539 buffer as needed. Keep track separately whether the format is
17540 multibyte. Keep only the most-recently calculated precision, rather
17541 than them all. Record whether each argument has been converted to
17542 string. Use EMACS_INT, not int, for byte and char and arg counts.
17543 Support field widths and precisions larger than INT_MAX. Avoid
17544 sprintf's undefined behavior with conversion specifications such as %#d
17545 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17546 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17547 formatting out-of-range floating point numbers with int
17548 formats. (Bug#8668)
17550 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17552 * data.c: Avoid integer truncation in expressions involving floats.
17553 * data.c: Include <intprops.h>.
17554 (arith_driver): When there's an integer overflow in an expression
17555 involving floating point, convert the integers to floating point
17556 so that the resulting value does not suffer from catastrophic
17557 integer truncation. For example, on a 64-bit host (* 4
17558 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17559 Do not rely on undefined behavior after integer overflow.
17561 merge count_size_as_multibyte, parse_str_to_multibyte
17562 * character.c, character.h (count_size_as_multibyte):
17563 Rename from parse_str_to_multibyte; all uses changed.
17564 Check for integer overflow.
17565 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17566 since it's now a duplicate of the other. This is more of
17567 a character than a buffer op, so better that it's in character.c.
17568 * fns.c, print.c: Adjust to above changes.
17570 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17572 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17574 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17576 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17577 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17578 (x_clipboard_manager_save): Now static.
17579 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17581 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17582 (crypto_hash_function): Now static.
17583 Fix pointer signedness problems. Avoid unnecessary initializations.
17585 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17587 * termhooks.h (Vselection_alist): Make it terminal-local.
17589 * terminal.c (create_terminal): Initialize it.
17591 * xselect.c: Support for clipboard managers.
17592 (Vselection_alist): Move to termhooks.h as terminal-local var.
17593 (LOCAL_SELECTION): New macro.
17594 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17595 (symbol_to_x_atom): Remove gratuitous arg.
17596 (x_handle_selection_request, lisp_data_to_selection_data)
17597 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17598 (x_own_selection, x_get_local_selection, x_convert_selection):
17599 New arg, specifying work frame. Use terminal-local Vselection_alist.
17600 (some_frame_on_display): Delete unused function.
17601 (Fx_own_selection_internal, Fx_get_selection_internal)
17602 (Fx_disown_selection_internal, Fx_selection_owner_p)
17603 (Fx_selection_exists_p): New optional frame arg.
17604 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17605 (x_handle_selection_clear): Don't treat other terminals with the
17606 same keyboard specially. Use the terminal-local Vselection_alist.
17607 (x_clear_frame_selections): Use Frun_hook_with_args.
17609 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17611 * xterm.h: Add support for those atoms.
17613 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17615 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17616 (converted_selections, conversion_fail_tag): New global variables.
17617 (x_selection_request_lisp_error): Free the above.
17618 (x_get_local_selection): Remove unnecessary code.
17619 (x_reply_selection_request): Args changed; handle arbitrary array
17620 of converted selections stored in converted_selections.
17621 Separate the XChangeProperty and SelectionNotify steps.
17622 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17623 (x_convert_selection): New function.
17624 (x_handle_selection_event): Simplify.
17625 (x_get_foreign_selection): Don't ignore incoming requests while
17626 waiting for an answer; this will fail when we implement
17627 SAVE_TARGETS, and seems unnecessary anyway.
17628 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17629 (Vx_sent_selection_functions): Doc fix.
17631 2011-05-26 Leo Liu <sdl.web@gmail.com>
17633 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17635 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17637 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17639 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17640 for fringe update if it has periodic bitmap.
17641 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17642 and fringe_bitmap_periodic_p.
17644 * fringe.c (get_fringe_bitmap_data): New function.
17645 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17646 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17647 row. Mark glyph row for fringe update if periodicity changed.
17649 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17650 for fringe update unless it has periodic bitmap.
17652 2011-05-25 Kenichi Handa <handa@m17n.org>
17654 * xdisp.c (get_next_display_element): Set correct it->face_id for
17655 a static composition.
17657 2011-05-24 Leo Liu <sdl.web@gmail.com>
17660 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17662 * fns.c (crypto_hash_function, Fsha1): New function.
17663 (Fmd5): Use crypto_hash_function.
17664 (syms_of_fns): Add Ssha1.
17666 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17668 * gnutls.c: Remove unused macros.
17669 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17670 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17671 Remove macros that are defined and never used.
17672 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17674 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17676 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17677 (Fx_get_selection_internal): Minor cleanup.
17678 (Fx_own_selection_internal): Rename arguments for consistency with
17681 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17683 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17685 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17687 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17689 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17691 * dispnew.c (scrolling_window): Don't exclude the case that the
17692 last enabled row in the desired matrix touches the bottom boundary.
17694 2011-05-21 Glenn Morris <rgm@gnu.org>
17696 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17697 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17698 and add some more files.
17700 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17702 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17703 report_file_error introduced by the change from 2011-05-07.
17705 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17707 * systime.h (Time): Define only if emacs is defined.
17708 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17709 where the include path doesn't have X11/X.h by default. See
17710 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17712 2011-05-20 Kenichi Handa <handa@m17n.org>
17714 * composite.c (find_automatic_composition): Fix previous change.
17716 2011-05-20 Glenn Morris <rgm@gnu.org>
17718 * lisp.mk: New file, split from Makefile.in.
17719 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17720 (shortlisp): Remove.
17721 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17723 2011-05-19 Glenn Morris <rgm@gnu.org>
17725 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17726 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17727 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17728 (lisp): Set the order to that of loadup.el.
17729 (shortlisp): Make it a copy of $lisp.
17730 (SOME_MACHINE_LISP): Remove.
17731 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17732 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17734 2011-05-18 Kenichi Handa <handa@m17n.org>
17736 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17737 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17738 (find_automatic_composition): Mostly rewrite for efficiency.
17740 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17742 * makefile.w32-in: Update dependencies.
17744 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17746 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17747 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17749 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17751 Fix some integer overflow issues, such as string length overflow.
17753 * insdel.c (count_size_as_multibyte): Check for string overflow.
17755 * character.c (lisp_string_width): Check for string overflow.
17756 Use EMACS_INT, not int, for string indexes and lengths; in
17757 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17758 the resulting string length overflows an EMACS_INT; instead,
17759 report a string overflow if no precision given. When checking for
17760 precision exhaustion, use a check that cannot possibly have
17761 integer overflow. (Bug#8675)
17762 * character.h (lisp_string_width): Adjust to new signature.
17764 * alloc.c (string_overflow): New function.
17765 (Fmake_string): Use it. This doesn't change behavior, but saves
17766 a few bytes and will simplify future changes.
17767 * character.c (string_escape_byte8): Likewise.
17768 * lisp.h (string_overflow): New decl.
17770 Fixups, following up to the user-interface timestamp change.
17771 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17772 for UI timestamps, instead of unsigned long.
17773 * msdos.c (mouse_get_pos): Likewise.
17774 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17775 * w32gui.h (Time): Define by including "systime.h" rather than by
17776 declaring it ourselves. (Bug#8664)
17778 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17779 * image.c (clear_image_cache): Likewise.
17781 * term.c (term_mouse_position): Don't assume time_t wraparound.
17783 Be more systematic about user-interface timestamps.
17784 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17785 and sometimes 'EMACS_UINT', to represent these timestamps.
17786 This change causes it to use 'Time' uniformly, as that's what X uses.
17787 This makes the code easier to follow, and makes it easier to catch
17788 integer overflow bugs such as Bug#8664.
17789 * frame.c (Fmouse_position, Fmouse_pixel_position):
17790 Use Time, not unsigned long, for user-interface timestamps.
17791 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17792 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17793 * keyboard.h (last_event_timestamp): Likewise.
17794 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17795 * menu.h (xmenu_show): Likewise.
17796 * term.c (term_mouse_position): Likewise.
17797 * termhooks.h (struct input_event.timestamp): Likewise.
17798 (struct terminal.mouse_position_hook): Likewise.
17799 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17800 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17801 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17802 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17803 what it was before.
17804 * menu.h, termhooks.h: Include "systime.h", for Time.
17806 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17807 Don't assume that the difference between two unsigned long values
17808 can fit into an integer. At this point, we know button_down_time
17809 <= event->timestamp, so the difference must be nonnegative, so
17810 there's no need to cast the result if double-click-time is
17811 nonnegative, as it should be; check that it's nonnegative, just in
17812 case. This bug is triggered when events are more than 2**31 ms
17813 apart (about 25 days). (Bug#8664)
17815 * xselect.c (last_event_timestamp): Remove duplicate decl.
17816 (x_own_selection): Remove needless cast to unsigned long.
17818 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17819 that always fit in int. Use a sentinel instead of a counter, to
17820 avoid a temp and to allay GCC's concerns about possible int overflow.
17821 * frame.h (struct frame): Use int for menu_bar_items_used
17822 instead of EMACS_INT, since it always fits in int.
17824 * menu.c (grow_menu_items): Check for int overflow.
17826 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17828 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17829 Before, the code was not consistent. These values cannot exceed
17830 2**31 - 1 so there's no need to make them unsigned.
17831 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17832 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17833 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17835 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17837 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17838 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17839 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17840 presumably because the widths might not match.
17842 * window.c (size_window): Avoid needless test at loop start.
17844 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17846 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17848 2011-05-12 Drew Adams <drew.adams@oracle.com>
17850 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17852 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17854 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17855 `width' to `bar_area_x' and `bar_area_width', respectively.
17856 (x_scroll_run): Take account of fringe background extension.
17858 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17859 Rename local vars `left' and `width' to `bar_area_x' and
17860 `bar_area_width', respectively.
17861 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17862 background extension.
17864 2011-05-10 Jim Meyering <meyering@redhat.com>
17866 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17868 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17870 * image.c (Finit_image_library): Return t for built-in image types,
17871 like pbm and xbm. (Bug#8640)
17873 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17875 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17877 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17879 * w32console.c (Fset_screen_color): Doc fix.
17880 (Fget_screen_color): New function.
17881 (syms_of_ntterm): Defsubr it.
17883 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17884 unlink the temporary file if Fcall_process didn't create it in the
17886 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17887 child process will be redirected to a file specified with `:file'.
17888 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17889 cue to call_process_cleanup not to close that handle.
17891 2011-05-07 Ben Key <bkey76@gmail.com>
17893 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17894 one of two shell specific rules, either bootstrap-temacs-CMD or
17895 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17896 to the previous implementation of the bootstrap-temacs rule.
17897 The bootstrap-temacs-CMD rule is similar to the previous
17898 implementation of the bootstrap-temacs rule except that it
17899 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17902 These changes, along with some changes to nt/configure.bat,
17903 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17904 earlier fix to add support for --cflags and --ldflags options
17905 that include quotes so that it works whether make uses cmd or
17908 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17910 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17911 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17913 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17914 a string. Handle both cases.
17915 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17916 (Fdbus_register_method): Use Qinvalid_function.
17918 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17920 * makefile.w32-in: Update dependencies.
17921 (LISP_H): Add inttypes.h and stdin.h.
17922 (PROCESS_H): Add unistd.h.
17924 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17926 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17927 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17929 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17931 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17933 * term.c (vfatal): Remove stray call to va_end.
17934 It's not needed and the C Standard doesn't allow it here anyway.
17936 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17937 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17939 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17942 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17944 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17946 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17948 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17950 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17952 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17953 * charset.c (Fdefine_charset_internal): Don't initialize
17954 charset.code_space[15]. The value was garbage, on hosts with
17955 32-bit int (Bug#8600).
17957 * lread.c (read_integer): Be more consistent with string-to-number.
17958 Use string_to_number to do the actual conversion; this avoids
17959 rounding errors and fixes some other screwups. Without this fix,
17960 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17961 (digit_to_number): Move earlier, for benefit of read_integer.
17962 Return -1 if the digit is out of range for the base, -2 if it is
17963 not a digit in any supported base. (Bug#8602)
17965 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17967 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17968 to match comment at start of function. This also removes a
17969 GCC warning about overflow in a 32+64-bit port.
17971 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17973 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17974 Reported by Stefan Monnier in
17975 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17976 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17977 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17979 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17980 (EMACS_UINTPTR): Likewise, with uintptr_t.
17982 * lisp.h: Prefer 64-bit EMACS_INT if available.
17983 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17984 on 32-bit hosts that have 64-bit int, so that they can access
17986 However, temporarily disable this change unless the temporary
17987 symbol WIDE_EMACS_INT is defined.
17989 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17991 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17992 This removes an assumption that EMACS_INT and long are the same
17993 width as pointers. The assumption is true for Emacs porting targets
17994 now, but we want to make other targets possible.
17995 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17996 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17997 In the rest of the code, change types of integers that hold casted
17998 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17999 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18000 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18001 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18002 No need to cast type when ORing.
18003 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18004 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18005 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18006 assume EMACS_INT is the same width as char *.
18007 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18008 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18009 Remove no-longer-needed casts.
18010 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18011 (xg_tool_bar_help_callback, xg_make_tool_item):
18012 Use EMACS_INTPTR to hold an integer
18013 that will be cast to void *; this can avoid a GCC warning
18014 if EMACS_INT is not the same width as void *.
18015 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18016 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18017 (current_message_1, set_message_1):
18018 Use a local to convert to proper width without a cast.
18019 * xmenu.c (dialog_selection_callback): Likewise.
18021 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18022 Also, don't assume VALBITS / RAND_BITS is less than 5,
18023 and don't rely on undefined behavior when shifting a 1 left into
18025 * lisp.h (get_random): Change signature to match.
18027 * lread.c (hash_string): Use size_t, not int, for hash computation.
18028 Normally we prefer signed values; but hashing is special, because
18029 it's better to use unsigned division on hash table sizes so that
18030 the remainder is nonnegative. Also, size_t is the natural width
18031 for hashing into memory. The previous code used 'int', which doesn't
18032 retain enough info to hash well into very large tables.
18033 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18035 * dbusbind.c: Don't possibly lose pointer info when converting.
18036 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18037 Use XPNTR rather than XHASH, so that the high-order bits of
18038 the pointer aren't lost when converting through void *.
18040 * eval.c (Fautoload): Don't double-shift a pointer.
18042 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18044 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18046 * gnutls.c (DEF_GNUTLS_FN):
18047 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18049 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18051 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18054 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18056 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18057 New version that can reserve upto 2GB of heap space.
18059 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18061 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18063 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18065 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18066 `gnutls_certificate_set_x509_key_file'.
18068 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18070 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18071 Update dependencies.
18073 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18075 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18076 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18077 Remove unused parameter `fildes'.
18078 * process.c (read_process_output, send_process): Don't pass it.
18080 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18082 Fix previous change: the library cache is defined in w32.c.
18083 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18084 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18086 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18088 Implement dynamic loading of GnuTLS on Windows.
18090 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18091 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18092 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18095 * gnutls.c (Qgnutls_dll): Define.
18096 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18097 (gnutls_*): Declare function pointers.
18098 (init_gnutls_functions): New function to initialize function pointers.
18099 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18100 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18101 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18102 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18103 (emacs_gnutls_write, emacs_gnutls_read)
18104 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18105 (Fgnutls_available_p): New function.
18106 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18107 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18108 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18110 * image.c: Include w32.h.
18111 (Vimage_type_cache): Delete.
18112 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18113 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18114 (w32_delayed_load): Move to w32.c.
18116 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18118 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18119 (w32_delayed_load): Move from image.c. When loading a library, record
18120 its filename in the :loaded-from property of the library id.
18121 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18122 Initialize and staticpro them.
18123 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18125 * process.c: Include lisp.h before w32.h, not after.
18126 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18127 instead of gnutls_record_check_pending.
18129 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18131 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18133 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18134 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18137 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18139 * xterm.c (x_set_frame_alpha): Do not set property on anything
18140 else than FRAME_X_OUTER_WINDOW (Bug#8608).

18158 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18160 * callproc.c: Indentation fixup.
18162 * sysdep.c (wait_for_termination_1): Make static.
18163 (wait_for_termination, interruptible_wait_for_termination):
18164 Move after wait_for_termination_1.
18166 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18168 * sysdep.c (interruptible_wait_for_termination): New function
18169 which is like wait_for_termination, but allows keyboard
18172 * callproc.c (Fcall_process): Add (:file "file") as an option for
18174 (Fcall_process_region): Ditto.
18176 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18178 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18179 rather than `XVECTOR (FOO)->size'.
18181 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18182 inttypes.h, as a gnulib replacement is used if it not available in
18185 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18187 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18188 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18189 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18191 * coding.c (coding_alloc_by_realloc): Error out if destination
18192 will grow beyond MOST_POSITIVE_FIXNUM.
18193 (decode_coding_emacs_mule): Abort if there isn't enough place in
18194 charbuf for the composition carryover bytes. Reserve an extra

18202 aborting when %lld or %lll format is passed.
18203 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18204 %llo or %llx format is passed. (Bug#8545)
18206 * window.c (window_scroll_line_based): Use a marker instead of
18207 simple variables to record original value of point. (Bug#7952)
18209 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18210 produced by %s or %c overflows available buffer space. (Bug#8545)
18212 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18214 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18215 (SIZE_MAX): Move defn after all includes, as they might #define it.
18217 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18219 * w32.c (init_environment): Warn about defaulting HOME to C:\.

18237 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18239 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18241 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18243 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18245 * makefile.w32-in: Update dependencies.
18247 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18249 Improve `doprnt' and its usage. (Bug#8545)
18250 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18251 `format_end'. Remove support for %l as a conversion specifier.
18252 Don't use xrealloc. Improve diagnostics when the %l size modifier
18253 is used. Update the commentary.
18255 * eval.c (verror): Simplify calculation of size_t.
18257 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18260 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18262 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18265 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18267 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18268 This makes this file independent of the recent pseudovector change.
18270 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18272 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18274 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18275 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18276 Remove unused local.
18277 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18279 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18280 GCC 4.6.0 optimizes based on type-based alias analysis.
18281 For example, if b is of type struct buffer * and v of type struct
18282 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18283 != &v->size, and therefore "v->size = 1; b->size = 2; return
18284 v->size;" must therefore return 1. This assumption is incorrect
18285 for Emacs, since it type-puns struct Lisp_Vector * with many other
18286 types. To fix this problem, this patch adds a new type struct
18287 vectorlike_header that documents the constraints on layout of vectors
18288 and pseudovectors, and helps optimizing compilers not get fooled
18289 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18290 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18291 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18293 (XSETPVECTYPE): Rewrite in terms of new macro.
18294 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18295 This is a bit clearer, and further avoids the possibility of
18296 undesirable aliasing.
18297 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18298 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18299 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18300 since Lisp_Subr is a special case (no "next" field).
18301 (ASIZE): Now uses header.size rather than size.
18302 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18303 to avoid the hassle of writing XVECTOR (foo)->header.size.
18304 (struct vectorlike_header): New type.
18305 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18306 object, to help avoid aliasing.
18307 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18308 (SUBRP): Likewise, since Lisp_Subr is a special case.
18309 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18310 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18311 (struct Lisp_Hash_Table): Combine first two members into a single
18312 struct vectorlike_header member. All uses of "size" and "next" members
18313 changed to be "header.size" and "header.next".
18314 * buffer.h (struct buffer): Likewise.
18315 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18316 * frame.h (struct frame): Likewise.
18317 * process.h (struct Lisp_Process): Likewise.
18318 * termhooks.h (struct terminal): Likewise.
18319 * window.c (struct save_window_data, struct saved_window): Likewise.
18320 * window.h (struct window): Likewise.
18321 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18322 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18323 * buffer.c (init_buffer_once): Likewise.
18324 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18326 * process.c (Fformat_network_address): Use local var for size,
18329 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18331 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18332 * data.c (atof): Remove decl; no longer used or needed.
18333 (digit_to_number): Move to lread.c.
18334 (Fstring_to_number): Use new string_to_number function, to be
18335 consistent with how the Lisp reader treats infinities and NaNs.
18336 Do not assume that floating-point numbers represent EMACS_INT
18337 without losing information; this is not true on most 64-bit hosts.
18338 Avoid double-rounding errors, by insisting on integers when
18339 parsing non-base-10 numbers, as the documentation specifies.
18340 * lisp.h (string_to_number): New decl, replacing ...
18341 (isfloat_string): Remove.
18342 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18343 (read1): Do not accept +. and -. as integers; this
18344 appears to have been a coding error. Similarly, do not accept
18345 strings like +-1e0 as floating point numbers. Do not report
18346 overflow for integer overflows unless the base is not 10 which
18347 means we have no simple and reliable way to continue.
18348 Break out the floating-point parsing into a new
18349 function string_to_number, so that Fstring_to_number parses
18350 floating point numbers consistently with the Lisp reader.
18351 (digit_to_number): Move here from data.c. Make it static inline.
18352 (E_CHAR, EXP_INT): Remove, replacing with ...
18353 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18354 (string_to_number): New function, replacing isfloat_string.
18355 This function checks for valid syntax and produces the resulting
18356 Lisp float number too. Rework it so that string-to-number
18357 no longer mishandles examples like "1.0e+". Use strtoumax,
18358 so that overflow for non-base-10 numbers is reported only when
18359 there's no portable and simple way to convert to floating point.
18361 * textprop.c (set_text_properties_1): Rewrite for clarity,
18362 and to avoid GCC warning about integer overflow.
18364 * intervals.h (struct interval): Use EMACS_INT for members
18365 where EMACS_UINT might cause problems. See
18366 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18367 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18368 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18370 (offset_intervals): Tell GCC not to worry about length overflow
18371 when negating a negative length.
18373 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18374 (overrun_check_free): Likewise.
18376 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18377 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18380 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18381 (gnutls_make_error): Rename local to avoid shadowing.
18382 (gnutls_emacs_global_deinit): ifdef out; not used.
18383 (Fgnutls_boot): Use const for pointer to readonly storage.
18384 Comment out unused local. Fix pointer signedness problems.
18386 * lread.c (openp): Don't stuff size_t into an 'int'.
18387 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18388 about possible signed overflow.
18390 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18391 (GDK_KEY_g): Don't define if already defined.
18392 (xg_prepare_tooltip): Avoid pointer signedness problem.
18393 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18395 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18396 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18398 * xfns.c (Fx_window_property): Simplify a bit,
18399 to make a bit faster and to avoid GCC 4.6.0 warning.
18400 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18402 * fns.c (internal_equal): Don't assume size_t fits in int.
18404 * alloc.c (compact_small_strings): Tighten assertion a little.
18406 Replace pEd with more-general pI, and fix some printf arg casts.
18407 * lisp.h (pI): New macro, generalizing old pEd macro to other
18408 conversion specifiers. For example, use "...%"pI"d..." rather
18409 than "...%"pEd"...".
18410 (pEd): Remove. All uses replaced with similar uses of pI.
18411 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18412 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18413 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18414 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18415 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18416 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18417 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18419 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18420 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18421 * print.c (safe_debug_print, print_object): Likewise.
18422 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18424 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18425 avoiding the 0 flag, which is not portable.
18426 * process.c (Fmake_network_process): Use pI to avoid cast.
18427 * region-cache.c (pp_cache): Likewise.
18428 * xdisp.c (decode_mode_spec): Likewise.
18429 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18430 behavior on 64-bit hosts with printf arg.
18431 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18432 (x_stop_queuing_selection_requests): Likewise.
18433 (x_get_window_property): Don't truncate byte count to an 'int'
18436 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18437 here, since it parses constructs like leading '-' and spaces,
18438 which are not wanted; and it overflows with large numbers.
18439 Instead, simply match F[0-9]+, which is what is wanted anyway.
18441 * alloc.c: Remove unportable assumptions about struct layout.
18442 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18443 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18444 (allocate_vectorlike, make_pure_vector): Use the new macros,
18445 plus offsetof, to remove unportable assumptions about struct layout.
18446 These assumptions hold on all porting targets that I know of, but
18447 they are not guaranteed, they're easy to remove, and removing them
18448 makes further changes easier.
18450 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18451 This doesn't fix a bug but makes the code clearer.
18452 (string_overrun_cookie): Now const. Use initializers that
18453 don't formally overflow signed char, to avoid warnings.
18454 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18455 can cause Emacs to crash when string overrun checking is enabled.
18456 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18457 multiple of sizeof (EMACS_INT); it need not be, if
18458 alignof(EMACS_INT) < sizeof (EMACS_INT).
18459 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18461 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18465 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18467 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18468 supposed to be handshaking. (Bug#8556)
18469 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18471 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18473 * lisp.h (Qdebug): List symbol.
18474 * eval.c (Qdebug): Restore global linkage.

18476 (handle_user_signal): Break into debugger when debug-on-event
18477 matches the current signal symbol.
18479 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18481 * alloc.c (check_sblock, check_string_bytes)
18482 (check_string_free_list): Convert to standard C.
18484 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18486 * w32.c (emacs_gnutls_push): Fix typo.
18488 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18490 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18491 "cast to pointer from integer of different size".
18493 Improve doprnt and its use in verror. (Bug#8545)
18494 * doprnt.c (doprnt): Document the set of format control sequences
18495 supported by the function. Use SAFE_ALLOCA instead of always
18498 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18499 is one byte too soon. Don't use xrealloc; instead xfree and
18502 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18504 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18507 * gnutls.c: Renamed global_initialized to
18508 gnutls_global_initialized. Added internals for the
18509 :verify-hostname-error, :verify-error, and :verify-flags
18510 parameters of `gnutls-boot' and documented those parameters in the
18511 docstring. Start callback support.
18512 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18513 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18514 on error. Return error code.
18515 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18516 (emacs_gnutls_read): Likewise.
18517 (Fgnutls_boot): Return handshake error code.
18518 (emacs_gnutls_handle_error): New function.
18519 (wsaerror_to_errno): Likewise.

18581 <char-direction-table>: Deleted.
18583 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18585 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
18586 * doprnt.c: Include limits.h.
18587 (SIZE_MAX): New macro.
18588 (doprnt): Return a size_t value. 2nd arg is now size_t.
18589 Many local variables are now size_t instead of int or unsigned.
18590 Improve overflow protection. Support `l' modifier for integer
18591 conversions. Support %l conversion. Don't assume an EMACS_INT
18592 argument for integer conversions and for %c.
18594 * lisp.h (doprnt): Restore prototype.
18596 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18597 $(SRC)/character.h.
18599 * Makefile.in (base_obj): Add back doprnt.o.
18601 * deps.mk (doprnt.o): Add back prerequisites.
18602 (callint.o): Depend on character.h.
18604 * eval.c (internal_lisp_condition_case): Include the handler
18605 representation in the error message.
18606 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
18607 when breaking from the loop.
18609 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
18611 * callint.c (Fcall_interactively): When displaying error message
18612 about invalid control letter, pass the character's codepoint, not
18613 a pointer to its multibyte form. Improve display of the character
18614 in octal and display also its hex code.
18616 * character.c (char_string): Use %x to display the (unsigned)
18617 codepoint of an invalid character, to avoid displaying a bogus
18620 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18621 `error', not SYMBOL_NAME itself.
18623 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18624 character arguments to `error'.
18626 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18627 to `error' in error message about FINAL_CHAR argument. Make sure
18628 FINAL_CHAR is a character, and use %c when it is passed as
18629 argument to `error'.

18818 * nsfont.m: Fixed bugs in ns_get_family and
18819 ns_descriptor_to_entity that were caused by using free to
18820 deallocate memory blocks that were allocated by xmalloc (via
18821 xstrdup). This caused Emacs to crash when compiled with
18822 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18823 --enable-checking=xmallocoverrun). xfree is now used to
18824 deallocate these memory blocks.

18841 (emacs_read, emacs_write): Use it.
18842 * process.c (send_process): Adjust to the new signatures of
18843 emacs_write and emacs_gnutls_write. Do not attempt to store

19169 * category.h: ... from here.
19170 * category.c (check_category_table, set_category_set): Now static.
19172 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
19173 * lisp.h: Remove these decls.
19175 * buffer.c (buffer_count): Remove unused var.
19177 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
19178 so that it's not optimized away.
19179 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
19180 * dispextern.h (bidi_dump_cached_states): Remove, since it's
19181 exported only to the debugger.
19183 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
19184 * atimer.h (run_all_atimers): Remove; not exported.
19186 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19187 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19188 was inaccessible from Lisp.
19189 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19190 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19192 alloc.c: Import and export fewer symbols, and remove unused items.
19193 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19195 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19196 it's not optimized away by whole-program optimization.
19197 (message_enable_multibyte, free_misc): Remove.
19198 (catchlist, handlerlist, mark_backtrace):
19199 Declare only if BYTE_MARK_STACK.
19200 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
19201 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
19202 (message_enable_multibyte): Remove decl.

19208 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
19209 (mark_backtrace): Define only if BYTE_MARK_STACK.
19210 * xdisp.c (message_enable_multibyte): Now static.
19212 Declare Lisp_Object Q* variables to be 'static' if not exported.
19213 This makes it easier for human readers (and static analyzers)
19214 to see whether these variables are used from other modules.
19215 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
19216 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
19217 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

19220 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
19221 * xmenu.c, xselect.c:
19222 Declare Q* vars static if they are not used in other modules.

19224 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
19225 Remove decls of unexported vars.
19226 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19228 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19230 Make Emacs functions such as Fatom 'static' by default.
19231 This makes it easier for human readers (and static analyzers)
19232 to see whether these functions can be called from other modules.
19233 DEFUN now defines a static function. To make the function external
19234 so that it can be used in other C modules, use the new macro DEFUE.
19235 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19236 (Finit_image_library):
19237 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19238 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19239 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19240 Remove decls, since these functions are now static.
19241 (Funintern, Fget_internal_run_time): New decls, since these functions
19242 were already external.
19244 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19245 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

19251 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19252 Mark functions with DEFUE instead of DEFUN,
19253 if they are used in other modules.
19254 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19255 decls for now-static functions.
19256 * buffer.h (Fdelete_overlay): Remove decl.
19257 * callproc.c (Fgetenv_internal): Mark as internal.

19266 * image.c (Finit_image_library): New forward static decl.
19267 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19268 * intervals.h (Fprevious_property_change):
19269 (Fremove_list_of_text_properties): Remove decls.
19270 * keyboard.c (Fthis_command_keys): Remove decl.
19271 (Fcommand_execute): New forward static decl.

19287 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
19289 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
19292 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19294 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19295 when at ZV. (Bug#8487)
19297 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19299 * charset.c (Fclear_charset_maps): Use xfree instead of free.

19302 * sound.c (sound_cleanup, alsa_close): Likewise.
19303 * termcap.c (tgetent): Likewise.
19304 * xfns.c (x_default_font_parameter): Likewise.
19305 * xsettings.c (read_and_apply_settings): Likewise.
19307 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19308 (overrun_check_free): Protoize.
19310 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19312 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19313 since callers should never pass a negative size.
19314 Change the signature to match that of plain 'read' and 'write'; see
19315 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19316 * lisp.h: Update prototypes of emacs_write and emacs_read.
19318 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19320 * xdisp.c (redisplay_window): Don't try to determine the character
19321 position of the scroll margin if the window start point w->startp
19322 is outside the buffer's accessible region. (Bug#8468)
19324 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19326 Fix write-region and its subroutines for buffers > 2GB.
19327 * fileio.c (a_write, e_write): Modify declaration of arguments and
19328 local variables to support buffers larger than 2GB.
19329 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19331 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19332 argument, local variables, and return value.
19334 * lisp.h: Update prototypes of emacs_write and emacs_read.
19336 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19338 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19340 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19342 Fix more problems found by GCC 4.6.0's static checks.
19344 * xdisp.c (vmessage): Use a better test for character truncation.
19346 * charset.c (load_charset_map): <, not <=, for optimization,
19347 and to avoid potential problems with integer overflow.
19348 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19349 * casetab.c (set_identity, shuffle): Likewise.
19350 * editfns.c (Fformat): Likewise.
19351 * syntax.c (skip_chars): Likewise.
19353 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19354 This also lets GCC 4.6.0 generate slightly better loop code.
19356 * callint.c (Fcall_interactively): <, not <=, for optimization.
19357 (Fcall_interactively): Count the number of arguments produced,
19358 not the number of arguments given. This is simpler and lets GCC
19359 4.6.0 generate slightly better code.
19361 * ftfont.c: Distingish more carefully between FcChar8 and char.
19362 The previous code passed unsigned char * to a functions like
19363 strlen and xstrcasecmp that expect char *, which does not
19364 conform to the C standard.
19365 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19366 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19367 char * when the C standard requires it.
19369 * keyboard.c (read_char): Remove unused var.
19371 * eval.c: Port to Windows vsnprintf (Bug#8435).
19372 Include <limits.h>.
19373 (SIZE_MAX): Define if the headers do not.
19374 (verror): Do not give up if vsnprintf returns a negative count.
19375 Instead, grow the buffer. This ports to Windows vsnprintf, which
19376 does not conform to C99. Problem reported by Eli Zaretskii.
19377 Also, simplify the allocation scheme, by avoiding the need for
19378 calling realloc, and removing the ALLOCATED variable.
19380 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19382 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19383 But keep the doprint source code for now, as we might revamp it
19384 and use it again (Bug#8435).
19385 * lisp.h (doprnt): Remove.
19386 * Makefile.in (base_obj): Remove doprnt.o.
19387 * deps.mk (doprnt.o): Remove.
19389 error: Print 32- and 64-bit integers portably (Bug#8435).
19390 Without this change, on typical 64-bit hosts error ("...%d...", N)
19391 was used to print both 32- and 64-bit integers N, which relied on
19392 undefined behavior.
19393 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19394 * lisp.h (error, verror): Mark as printf-like functions.
19395 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19396 Report overflow in size calculations when allocating printf buffer.
19397 Do not truncate output string at its first null byte.
19398 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19399 Truncate the output at a character boundary, since vsnprintf does not
19401 * charset.c (check_iso_charset_parameter): Convert internal
19402 character to string before calling 'error', since %c now has the
19404 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19405 overflow when computing char to be passed to 'error'. Do not
19406 pass Lisp_Object to 'error'; pass the integer instead.
19407 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19408 formatted with plain %d.
19410 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19412 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19414 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19416 * xterm.c (x_catch_errors): Remove duplicate declaration.
19418 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19420 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19422 2011-04-10 Jim Meyering <meyering@redhat.com>
19424 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19425 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19426 return ssize_t not "int", and use size_t as the buffer length.
19427 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19428 * gnutls.h: Update declarations.
19429 * process.c (read_process_output): Use ssize_t, to match.
19430 (send_process): Likewise.
19432 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19434 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19436 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19438 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19439 Use unsigned char, to match FcChar8 type definition.
19441 * xterm.c (handle_one_xevent):
19442 * xmenu.c (create_and_show_popup_menu):
19443 * xselect.c (x_decline_selection_request)
19444 (x_reply_selection_request): Avoid type-punned deref of X events.
19446 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19448 Fix some uses of `int' instead of EMACS_INT.
19449 * search.c (string_match_1, fast_string_match)
19450 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19451 (scan_buffer, find_next_newline_no_quit)
19452 (find_before_next_newline, search_command, Freplace_match)
19453 (Fmatch_data): Make some `int' variables be EMACS_INT.
19455 * xdisp.c (display_count_lines): 3rd argument and return value now
19456 EMACS_INT. All callers changed.
19457 (pint2hrstr): Last argument is now EMACS_INT.
19459 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19460 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19461 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
19462 (decode_coding_utf_16, decode_coding_emacs_mule)
19463 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
19464 (decode_coding_ccl, decode_coding_charset)
19465 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19466 (decode_coding_iso_2022, decode_coding_emacs_mule)
19467 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19468 <char_offset, last_offset>: Declare EMACS_INT.

19470 (encode_coding_emacs_mule, encode_invocation_designation)
19471 (encode_designation_at_bol, encode_coding_iso_2022)
19472 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19473 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19475 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19476 (encode_invocation_designation): Last argument P_NCHARS is now
19478 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19479 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19481 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19484 * ccl.c (Fccl_execute_on_string): Declare some variables
19487 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19489 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19491 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19493 * process.c (Fformat_network_address): Doc fix.
19495 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19497 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19499 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19501 * keyboard.c (read_char): Call Lisp function help-form-show,
19502 instead of using internal_with_output_to_temp_buffer.
19503 (Qhelp_form_show): New var.
19504 (syms_of_keyboard): Use DEFSYM macro.
19506 * print.c (internal_with_output_to_temp_buffer): Function deleted.
19508 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
19510 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19512 * process.c (Flist_processes): Remove to Lisp.
19513 (list_processes_1): Delete.
19515 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19517 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19519 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19521 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19523 Fix more problems found by GCC 4.6.0's static checks.
19525 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19527 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19529 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19531 * xdisp.c (vmessage): Mark as a printf-like function.
19533 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19535 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19537 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19538 printf-like functions.
19539 (tiff_load): Add casts to remove these marks before passing them
19540 to system-supplied API.
19542 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19544 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19545 This avoids several warnings with gcc -Wstrict-overflow.
19546 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19547 directly, rather than having caller test rule sign. This avoids
19548 some unnecessary tests.
19549 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19550 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19551 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19553 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19554 (xfont_open): Avoid unnecessary tests.
19556 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19558 * composite.h, composite.c (composition_gstring_put_cache):
19559 Use EMACS_INT, not int, for length.
19561 * composite.h (COMPOSITION_DECODE_REFS): New macro,
19562 breaking out part of COMPOSITION_DECODE_RULE.
19563 (COMPOSITION_DECODE_RULE): Use it.
19564 * composite.c (get_composition_id): Remove unused local vars,
19565 by using the new macro.
19567 * textprop.c (set_text_properties_1): Change while to do-while,
19568 since the condition is always true at first.
19570 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19571 (interval_deletion_adjustment): Return unsigned value.
19574 * process.c (list_processes_1, create_pty, read_process_output):

19576 (create_pty): Remove unnecessary "volatile"s.
19577 (Fnetwork_interface_info): Avoid possibility of int overflow.

19590 * print.c (print_error_message): Avoid int overflow.
19592 * font.c (font_list_entities): Redo for clarity,
19593 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

19608 (wordify): Omit three unnecessary tests.
19610 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

19615 * dired.c (file_name_completion): Remove var that is set but not used.
19617 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19619 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19620 (Finsert_file_contents): Remove unnecessary code checking fd.
19622 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19623 Check for integer overflow on size calculations.
19625 * buffer.c (Fprevious_overlay_change): Remove var that is set
19628 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19629 Remove vars that are set but not used.
19630 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19631 (timer_check_2): Mark vars as initialized.
19633 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19635 * image.c (lookup_image): Remove var that is set but not used.
19636 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19638 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19639 that are set but not used.
19641 * xfns.c (make_invisible_cursor): Don't return garbage
19642 if XCreateBitmapFromData fails (Bug#8410).
19644 * xselect.c (x_get_local_selection, x_handle_property_notify):
19645 Remove vars that are set but not used.
19647 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19648 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19650 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19651 Remove var that is set but not used.
19652 (scroll_bar_windows_size): Now size_t, not int.
19653 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19654 Check for overflow.
19656 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19657 (map_tty_color) [!defined MSDOS]: Likewise.
19659 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19661 * coding.c: Remove vars that are set but not used.
19662 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19663 All callers changed.
19664 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19665 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19666 (decode_coding_charset): Remove vars that are set but not used.
19668 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19669 that is set but not used.
19671 * print.c (print_object): Remove var that is set but not used.
19673 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19674 The gnulib version avoids calling malloc in the usual case,
19675 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19676 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19677 * filelock.c (current_lock_owner): Likewise.
19678 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19679 * sysdep.c: Include allocator.h, careadlinkat.h.
19680 (emacs_no_realloc_allocator): New static constant.
19681 (emacs_readlink): New function.
19682 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19683 ../lib/careadlinkat.h.
19685 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19687 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19688 first non-nil return value).

19697 * xdisp.c (display_count_lines): Remove parameter `start',
19698 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19699 (get_char_face_and_encoding): Remove parameter `multibyte_p',

19702 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19703 and thereabouts. All callers changed.
19704 (get_per_char_metric): Remove parameter `f', unused since
19705 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19707 2011-04-02 Jim Meyering <meyering@redhat.com>
19709 do not dereference NULL upon failed strdup
19710 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19711 (ns_get_family): Likewise.
19713 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19715 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19717 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19719 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19722 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19724 Add lexical binding.
19726 * window.c (Ftemp_output_buffer_show): New fun.
19727 (Fsave_window_excursion):
19728 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19730 * lread.c (lisp_file_lexically_bound_p): New function.
19731 (Fload): Bind Qlexical_binding.
19732 (readevalloop): Remove `evalfun' arg.
19733 Bind Qinternal_interpreter_environment.
19734 (Feval_buffer): Bind Qlexical_binding.
19735 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19737 (syms_of_lread): Declare `lexical-binding'.
19739 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19741 * keyboard.c (eval_dyn): New fun.
19742 (menu_item_eval_property): Use it.
19744 * image.c (parse_image_spec): Use Ffunctionp.
19746 * fns.c (concat, mapcar1): Accept byte-code-functions.
19748 * eval.c (Fsetq): Handle lexical vars.
19749 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19750 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19751 (FletX, Flet): Obey lexical binding.
19752 (Fcommandp): Handle closures.
19753 (Feval): New `lexical' arg.
19754 (eval_sub): New function extracted from Feval. Use it almost
19755 everywhere where Feval was used. Look up vars in lexical env.
19757 (Ffunctionp): Move from subr.el.
19758 (Ffuncall): Handle closures.
19759 (apply_lambda): Remove `eval_flags'.
19760 (funcall_lambda): Handle closures and new byte-code-functions.
19761 (Fspecial_variable_p): New function.
19762 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19763 but without exporting it to Lisp.
19765 * doc.c (Fdocumentation, store_function_docstring):
19766 * data.c (Finteractive_form): Handle closures.
19768 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19771 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19773 (exec_byte_code): New function extracted from Fbyte_code to handle new
19774 calling convention for byte-code-functions. Add new byte-codes.
19776 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19778 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19780 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19782 * xdisp.c (redisplay_internal): Fix prototype.
19784 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19786 * xdisp.c (SCROLL_LIMIT): New macro.
19787 (try_scrolling): Use it when setting scroll_limit.
19788 Limit scrolling to 100 screen lines.
19789 (redisplay_window): Even when falling back on "recentering",
19790 position point in the window according to scroll-conservatively,
19791 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19793 (try_scrolling): When point is above the window, allow searching
19794 as far as scroll_max, or one screenful, to compute vertical
19795 distance from PT to the scroll margin position. This prevents
19796 try_scrolling from unnecessarily failing when
19797 scroll-conservatively is set to a value slightly larger than the
19798 window height. Clean up the case of PT below the margin at bottom
19799 of window: scroll_max can no longer be INT_MAX. When aggressive
19800 scrolling is in use, don't let point enter the opposite scroll
19801 margin as result of the scroll.
19802 (syms_of_xdisp) <scroll-conservatively>: Document the
19803 threshold of 100 lines for never-recentering scrolling.
19805 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19807 * dispextern.h (move_it_by_lines):

19810 (message_log_check_duplicate): Remove parameters `prev_bol' and
19811 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19812 (redisplay_internal): Remove parameter `preserve_echo_area',
19813 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19815 * indent.c (Fvertical_motion):
19816 * window.c (window_scroll_pixel_based, Frecenter):
19817 Don't pass `need_y_p' to `move_it_by_lines'.
19819 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19821 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19822 steal a few bits to be more compact.
19823 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19824 Remove unneeded casts.
19826 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19828 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19830 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19831 binding" message (bug#7967).
19833 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19835 Fix more problems found by GCC 4.6.0's static checks.
19837 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19838 Remove unused local var.
19840 * editfns.c (Fmessage_box): Remove unused local var.
19842 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19843 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19844 Omit unused local vars.
19845 * window.c (shrink_windows): Omit unused local var.
19846 * menu.c (digest_single_submenu): Omit unused local var.
19847 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19848 Omit unused local var.
19850 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19851 Don't assume string length fits in int.
19852 (keyremap_step, read_key_sequence): Use size_t for sizes.
19853 (read_key_sequence): Don't check last_real_key_start redundantly.
19855 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19856 instead of alloca (Bug#8344).
19858 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19859 (Fbacktrace_frame): Don't assume nframes fits in int.
19861 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

19866 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19868 * cm.c (calccost): Turn while-do into do-while, for clarity.
19870 * keyboard.c (syms_of_keyboard): Use the same style as later
19871 in this function when indexing through an array. This also
19872 works around GCC bug 48267.
19874 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19876 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19878 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19879 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19881 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19882 This avoids undefined behavior on integer overflow, and is a bit
19883 more convenient anyway since it is compared to a size_t variable.
19885 Variadic C functions now count arguments with size_t, not int.
19886 This avoids an unnecessary limitation on 64-bit machines, which
19887 caused (substring ...) to crash on large vectors (Bug#8344).

19897 * fns.c (concat): Likewise.
19898 * frame.c (x_set_frame_parameters): Likewise.
19899 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19900 0 if not found, not -1. All callers changed.
19902 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19903 (stack_copy_size): Now size_t, not int.
19904 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19906 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19908 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19909 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19910 All callers changed.
19912 * lisp.h (multibyte_char_to_unibyte):
19913 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19914 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19925 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19926 don't set the hook to nil, but remove the offending function instead.
19927 (Qcommand_hook_internal): Remove, unused.
19928 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19929 Vcommand_hook_internal.
19931 * eval.c (enum run_hooks_condition): Remove.
19932 (funcall_nil, funcall_not): New functions.
19933 (run_hook_with_args): Call each function through a `funcall' argument.
19934 Remove `cond' argument, now redundant.

19947 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19948 All callers changed.
19950 * w32.c (_wsa_errlist): Use braces for struct initializers.
19952 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
19953 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
19954 All callers changed.

20099 * term.c (Fsuspend_tty, Fresume_tty):
20100 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20101 * window.c (temp_output_buffer_show):

20109 * buffer.c (Fkill_all_local_variables):
20110 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20112 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20113 unconditionally since it does the check itself.
20115 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20117 Fix more problems found by GCC 4.5.2's static checks.
20119 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20120 the first time through the loop, since we know p0 < p1 then.
20121 This also avoids a gcc -Wstrict-overflow warning.
20123 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20124 leading to a memory leak, possible in functions like
20125 load_charset_map_from_file that can allocate an unbounded number
20126 of objects (Bug#8318).
20128 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20129 that could (at least in theory) be that large.
20131 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20132 This is less likely to overflow, and avoids undefined behavior if
20133 overflow does occur. All callers changed. Use strtoul to scan
20134 for the unsigned long integer.
20135 (pint2hrstr): Simplify and tune code slightly.
20136 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20146 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20149 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20151 * process.c (Fmake_network_process): Use socklen_t, not int,
20152 where POSIX says socklen_t is required in portable programs.
20153 This fixes a porting bug on hosts like 64-bit HP-UX, where
20154 socklen_t is wider than int (Bug#8277).
20155 (Fmake_network_process, server_accept_connection):
20156 (wait_reading_process_output, read_process_output):
20159 * process.c: Rename or move locals to avoid shadowing.

20169 Make tparam.h and terminfo.c consistent.
20170 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20171 Include tparam.h instead, since it declares them.
20172 * cm.h (PC): Remove extern decl; tparam.h now does this.
20173 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20174 * terminfo.c: Include tparam.h, to check interfaces.
20175 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20176 (tparam): Adjust signature to match interface in tparam.h;
20177 this removes some undefined behavior. Check that outstring and len
20178 are zero, which they always are with Emacs.
20179 * tparam.h (PC, BC, UP): New extern decls.
20181 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20182 (xftfont_open): Rename locals to avoid shadowing.

20199 (find_automatic_composition, composition_adjust_point): Likewise.
20200 (composition_update_it): Mark var as initialized.
20201 (find_automatic_composition): Mark vars as initialized,
20202 with a FIXME (Bug#8290).

20206 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20207 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20208 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20209 to avoid shadowing.
20211 * textprop.c (property_change_between_p): Remove; unused.
20213 * intervals.c (interval_start_pos): Now static.
20215 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20221 Fix pointer signedness.
20222 (alsa_choose_format): Remove unused local var.
20223 (wav_play): Initialize a variable to 0, to prevent undefined
20224 behavior (Bug#8278).
20226 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20228 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20230 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20231 clobbering (Bug#8298).
20232 * sysdep.c (sys_subshell): Likewise.
20233 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20235 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20236 This should get cleaned up, so that child_setup has the
20237 same signature on all platforms.
20239 * callproc.c (call_process_cleanup): Now static.
20240 (relocate_fd): Rename locals to avoid shadowing.
20242 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20244 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20245 not to be necessary, and produces flickering.
20247 2011-03-20 Glenn Morris <rgm@gnu.org>
20249 * config.in: Remove file.
20251 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20253 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20254 are now in src/globals.h.

20281 (sigchld_handler): Now static.
20283 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20284 That way, the code declares only the vars that it needs.

20295 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20296 Define only if needed.
20298 * unexelf.c (unexec): Name an expression,
20299 to avoid gcc -Wbad-function-cast warning.
20300 Use a different way to cause a compilation error if anyone uses
20301 n rather than nn, a way that does not involve shadowing.
20302 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20304 * deps.mk (unexalpha.o): Remove; unused.
20306 New file unexec.h, the (simple) interface for unexec (Bug#8267).

20377 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20380 * lisp.h (eassert): Check that the argument compiles, even if
20381 ENABLE_CHECKING is not defined.
20383 * data.c (Findirect_variable): Name an expression, to avoid
20384 gcc -Wbad-function-cast warning.

20401 (Fmemory_limit): Cast sbrk's returned value to char *.

20427 (RETALLOC_IF): Define only if needed.
20428 (WORDCHAR_P): Likewise. This one is never needed, but is used
20429 only in a comment talking about a compiler bug, so put inside
20430 the #if 0 of that comment.

20460 gcpro1, gcpro2, etc.
20461 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20463 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20464 argument, for consistency with GCPRO2_VAR, etc: it is now the

20468 Rename locals to avoid shadowing.
20470 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20471 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20472 dired.c's scmp function, had undefined behavior.

20474 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...

20476 and the new implementation with inline functions needs to have
20477 current_buffer in scope now, rather than later when the macros
20479 (downcase, upcase1): New static inline functions.
20480 (DOWNCASE, UPCASE1): Reimplement using these functions.
20481 This avoids undefined behavior in expressions like

20522 * buffer.c (fix_overlays_before): Mark locals as initialized.
20523 (fix_start_end_in_overlays): Likewise. This function should be
20524 simplified by using pointers-to-pointers, but that's a different

20533 to suppress a gcc -Wclobbered warning that does not seem to be right.
20534 (MAXPATHLEN): Define only if needed.
20536 * process.c (serial_open, serial_configure): Move decls from here ...
20537 * systty.h: ... to here, so that they can be checked.
20539 * fns.c (get_random, seed_random): Move extern decls from here ...

20551 (describe_map_tree):
20552 Rename locals to avoid shadowing.

20879 * coding.c (coding_set_source, coding_set_destination):

20883 a block, when the outer 'i' will do.
20884 (decode_coding_utf_8, decode_coding_utf_16, detect_coding_emacs_mule):

20895 (decode_coding_emacs_mule): Mark variables that gcc
20896 -Wuninitialized does not deduce are never used uninitialized.
20897 (detect_coding_iso_2022): Initialize a local variable that might
20898 be used uninitialized. Leave a FIXME because it's not clear that
20899 this initialization is needed. (Bug#8211)
