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

76 (record_infile, record_pending_deletion): New prototypes.
78 * w32proc.c (new_child): Initialize input_file and
79 pending_deletion members of the child.
80 (delete_child): Delete the child's temporary input file, if any,
81 that is pending deletion.

92 * callproc.c (Fcall_process): Don't overwrite infile with result
94 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
95 asynchronous subprocess, record the name of the input file name,
97 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
98 delete the file, record it as pending deletion when the subprocess
101 2012-12-14 Eli Zaretskii <eliz@gnu.org>

123 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
124 try to get accurate owner and group information from NT file
125 security APIs. This is to make most callers of 'stat' and
126 'lstat', which don't need that information, much faster.
128 * dired.c (Ffile_attributes) [WINDOWSNT]:
129 Set w32_stat_get_owner_group to a non-zero value, to request accurate
130 owner and group information from 'lstat'.
132 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
134 * fileio.c (Finsert_file_contents): Don't put tail into head area,
135 as that confuses set-auto-coding, so insist on the head-read
136 returning the full 1024 bytes. Let lseek compute the tail offset;
137 less work for us. Do not ignore I/O errors when reading the tail.

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

194 * xdisp.c (handle_face_prop): Fix logic of computing
195 it->start_of_box_run_p.
196 (append_space_for_newline): If the glyph row is R2L, reset the
197 iterator's end_of_box_run_p flag before prepending the space glyph.
198 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
199 iterator's start_of_box_run_p flag before prepending the stretch.

254 (_start): Remove initialization of above variables; remove
255 initialization of hinst, as cache_system_info now does that.

509 Fix a recently-introduced delete-process race condition.
510 * callproc.c, process.h (record_kill_process):
511 New function, containing part of the old call_process_kill.
512 (call_process_kill): Use it.
513 This does not change call_process_kill's behavior.
514 * process.c (Fdelete_process): Use record_kill_process to fix a
515 race condition that could cause Emacs to lose track of a child.
517 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
519 Avoid code duplication between prev_frame and next_frame.
520 * frame.c (candidate_frame): New function. Add comment.
521 (prev_frame, next_frame): Use it. Adjust comment.
523 2012-12-06 Eli Zaretskii <eliz@gnu.org>
525 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
526 fails, signal an error instead of continuing with an empty
528 Encode expanded temp file pattern before passing it to mkstemp or
531 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
532 Encode the file name before passing it to dostounix_filename, in
533 case it will downcase it (under w32-downcase-file-names).
536 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
538 Minor call-process cleanups.
539 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
540 at the same time as other platforms, to simplify analysis.
541 No need for fd0_volatile since we have synch_process_fd.
542 Avoid needless emacs_close; arg is always negative.
544 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
546 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
549 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
551 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
552 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
553 and mouse_face_hidden members to a bitfields.
554 * frame.h (struct frame): Remove set-but-not-used space_width member.
555 (FRAME_SPACE_WIDTH): Remove.
556 * nsterm.m, w32term.c, xterm.c: Adjust users.
557 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so

559 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
560 members to a bitfields.
562 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
564 Don't let call-process be a zombie factory (Bug#12980).
565 Fixing this bug required some cleanup of the signal-handling code.
566 As a side effect, this change also fixes a longstanding rare race
567 condition whereby Emacs could mistakenly kill unrelated processes,
568 and it fixes a bug where a second C-g does not kill a recalcitrant
569 synchronous process in GNU/Linux and similar platforms.
570 The patch should also fix the last vestiges of Bug#9488,
571 a bug which has mostly been fixed on the trunk by other changes.
572 * callproc.c, process.h (synch_process_alive, synch_process_death)
573 (synch_process_termsig, sync_process_retcode):
574 Remove. All uses removed, to simplify analysis and so that
575 less consing is done inside critical sections.
576 * callproc.c (call_process_exited): Remove. All uses replaced
577 with !synch_process_pid.
578 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
579 These take the role of what used to be in unwind-protect arg.
581 (block_child_signal, unblock_child_signal):
582 New functions, to avoid races that could kill innocent-victim processes.
583 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
584 (call_process_kill): Record killed processes as deleted, so that
585 zombies do not clutter up the system. Do this inside a critical
586 section, to avoid a race that would allow the clutter.
587 (call_process_cleanup): Fix code so that the second C-g works again
588 on common platforms such as GNU/Linux.
589 (Fcall_process): Create the child process in a critical section,
590 to fix a race condition. If creating an asynchronous process,
591 record it as deleted so that zombies do not clutter up the system.
592 Do unwind-protect for WINDOWSNT too, as that's simpler in the
593 light of these changes. Omit unnecessary call to emacs_close
594 before failure, as the unwind-protect code does that.
595 * callproc.c (call_process_cleanup):
596 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
597 * process.c (record_deleted_pid): New function, containing
598 code refactored out of Fdelete_process.
599 (Fdelete_process): Use it.
600 (process_status_retrieved): Remove. All callers changed to use
602 (record_child_status_change): Remove, folding its contents into ...
603 (handle_child_signal): ... this signal handler. Now, this
604 function is purely a handler for SIGCHLD, and is not called after
605 a synchronous waitpid returns; the synchronous code is moved to
606 wait_for_termination. There is no need to worry about reaping
607 more than one child now.
608 * sysdep.c (get_child_status, child_status_changed): New functions.
609 (wait_for_termination): Now takes int * status and bool
610 interruptible arguments, too. Do not record child status change;
611 that's now the caller's responsibility. All callers changed.
612 Reimplement in terms of get_child_status.
613 (wait_for_termination_1, interruptible_wait_for_termination):
614 Remove. All callers changed to use wait_for_termination.
615 * syswait.h: Include <stdbool.h>, for bool.
616 (record_child_status_change, interruptible_wait_for_termination):
618 (record_deleted_pid, child_status_changed): New decls.
619 (wait_for_termination): Adjust to API changes noted above.
621 * bytecode.c, lisp.h (Qbytecode): Remove.
622 No longer needed after 2012-11-20 interactive-p changes.
624 2012-12-03 Eli Zaretskii <eliz@gnu.org>
626 * xdisp.c (redisplay_window): If the cursor is visible, but inside
627 the scroll margin, move point outside the margin. (Bug#13055)
629 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
631 * gtkutil.c (my_log_handler): New function.

636 * lisp.h (modify_region): Rename to...
637 (modify_region_1): ...new prototype.

639 * insdel.c (modify_region): Rename to...
640 (modify_region_1): ...new function to work with current buffer.
641 Adjust comment and users. Use true and false for booleans.
643 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
645 * alloc.c (free_save_value): New function.
646 (safe_alloca_unwind): Use it.
647 * lisp.h (free_save_value): New prototype.
648 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
650 (save_excursion_restore): Adjust to match saved data structure.
651 Use free_save_value to offload some work from GC. Drop obsolete
654 2012-12-03 Chong Yidong <cyd@gnu.org>
656 * fileio.c (Vauto_save_list_file_name): Doc fix.
658 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
660 * w32fns.c: Remove prototype of atof.
661 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
663 (file_dialog_callback): Make it UINT_PTR.
665 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
668 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
669 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
672 2012-12-03 Glenn Morris <rgm@gnu.org>
674 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
676 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
678 Fix xpalloc confusion after memory is exhausted.
679 * alloc.c (xpalloc): Comment fix.
680 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
681 and signals an error, do not clear charset_table_size, as
682 charset_table is still valid.
683 * doprnt.c (evxprintf): Clear *BUF after freeing it.
685 Use execve to avoid need to munge environ (Bug#13054).
686 * callproc.c (Fcall_process):
687 * process.c (create_process):
688 Don't save and restore environ; no longer needed.
689 * callproc.c (child_setup):
690 Use execve, not execvp, to preserve environ.
692 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
694 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
696 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
698 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
699 display for sliced images (Bug#10500).

706 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
708 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
710 * xdisp.c (window_outdated): Remove eassert since it hits
711 some suspicious corner cases (see Bug#13007 and Bug#13012).
712 (mode_line_update_needed): New function.
713 (redisplay_internal, redisplay_window): Use it.
714 (ensure_selected_frame): New function.
715 (redisplay_internal, unwind_redisplay): Use it.
716 (redisplay_internal): Move comment about buffer_shared...
717 (buffer_shared_and_changed): ...near to its real use.
719 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>

723 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
725 * callproc.c (Fcall_process): Fix vfork portability problems.
726 Do not assume that fd[0], count, filefd, and save_environ survive
727 vfork. Fix bug whereby wrong errno value could be reported for
728 pipe failure. Some minor cleanups, too, as follows. Move buf and
729 bufsize to the context where they're needed. Change new_argv to
730 be of type char **, as this is more convenient and avoids casts.
731 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
732 Now local constants, not macros.
734 2012-11-18 Kenichi Handa <handa@gnu.org>
736 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
737 for the variable "f".
739 2012-11-13 Kenichi Handa <handa@gnu.org>
741 * font.c (font_unparse_xlfd): Exclude special characters from the
742 generating XLFD name.

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

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

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

978 * makefile.w32-in (SYSWAIT_H): New macro.
979 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
980 ($(BLD)/sysdep.$(O)): Update dependencies.
982 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
984 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
985 * callproc.c (relocate_fd): Assume F_DUPFD.
986 * emacs.c, term.c (O_RDWR): Remove.
987 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
988 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
989 * nsterm.m: Assume <fcntl.h> exists.
990 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
991 (create_pty, Fmake_network_process, server_accept_connection)
992 (wait_reading_process_output, init_process_emacs):
994 (wait_reading_process_output): Put in a special case for WINDOWSNT
995 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
996 It's not clear this is needed, but it's a more-conservative change.
997 (create_process): Assume FD_CLOEXEC.
998 (create_process, create_pty): Assume O_NOCTTY.
999 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1000 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1001 Omit if not DOS_NT, since F_GETFL is not defined there.
1002 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1003 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1005 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1006 lack it, since gnulib guarantees this.
1007 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1009 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1011 * w32.c (faccessat): Pretend that directories have the execute bit
1012 set. Emacs expects that, e.g., in files.el:cd-absolute.
1014 * w32proc.c (create_child): Don't clip the PID of the child
1015 process to fit into an Emacs integer, as this is no longer a
1017 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1018 reaping only the process specified by PID argument, if that is
1019 positive. Use PID instead of dead_child to know which process to
1020 reap. Wait for the child to die only if WNOHANG is not in
1022 (sys_select): Don't set dead_child.
1024 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1025 as it is no longer needed.
1027 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1029 (record_child_status_change): Remove the setting of
1030 record_at_most_one_child for the !WNOHANG case.
1032 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1034 Fix problems in ns port found by static checking.
1035 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1036 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1037 not to process group.
1038 (ns_select): Use emacs_write, not write, as that's more robust
1039 in the presence of signals.
1040 (fd_handler:): Check for read errors.
1042 2012-11-16 Glenn Morris <rgm@gnu.org>
1044 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1046 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1048 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1050 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1052 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1053 use the same value of thread handle.
1054 (start_timer_thread): If the timer thread exited (due to error),
1055 clean up by closing the two handles it used. Duplicate the caller
1056 thread's handle here, so it gets duplicated only once, when
1057 launching the timer thread. Set priority of the timer thread, not
1059 (getitimer): Don't duplicate the caller thread's handle here.
1062 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1064 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1067 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1069 Remove no-longer-used pty_max_bytes variable.
1070 * process.c (pty_max_bytes): Remove; unused.
1071 (send_process): Do not set it.
1073 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1075 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1076 Update dependencies.
1078 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1080 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1081 This follows up on the 2012-09-29 patch that removed indirection
1082 for the 'function' field. Reported by Sergey Vinokurov in
1083 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1085 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1087 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1088 different name, as the MS runtime does not have such a function,
1089 and probably never will.) All callers changed. Ignore DIRFD
1090 value if PATH is an absolute file name, to match Posix spec
1091 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1094 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1096 * xdisp.c (echo_area_display, redisplay_internal):
1097 Omit redundant check whether frame_garbaged is set.
1099 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1101 Use faccessat, not access, when checking file permissions (Bug#12632).
1102 This fixes a bug that has been present in Emacs since its creation.
1103 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1104 which must set some sort of record. (Torek's bug report was against
1105 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1106 same common flaw.) See Torek's Usenet posting
1107 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1108 Posted: Fri Apr 8 14:18:56 1983.
1109 * Makefile.in (LIB_EACCESS): New macro.
1111 * callproc.c (init_callproc):
1112 * charset.c (init_charset):
1113 * fileio.c (check_existing, check_executable, check_writable)
1115 * lread.c (openp, load_path_check):
1116 * process.c (allocate_pty):
1118 Use effective UID when checking permissions, not real UID.
1119 * callproc.c (init_callproc):
1120 * charset.c (init_charset):
1121 * lread.c (load_path_check, init_lread):
1122 Test whether directories are accessible, not merely whether they exist.
1123 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1124 * fileio.c (check_existing, check_executable, check_writable)
1126 Use symbolic names instead of integers for the flags, as they're
1128 (check_writable): New arg AMODE. All uses changed.
1129 Set errno on failure.
1130 (Ffile_readable_p): Use faccessat, not stat + open + close.
1131 (Ffile_writable_p): No need to call check_existing + check_writable.
1132 Just call check_writable and then look at errno. This saves a syscall.
1133 dir should never be nil; replace an unnecessary runtime check
1134 with an eassert. When checking the parent directory of a nonexistent
1135 file, check that the directory is searchable as well as writable, as
1136 we can't create files in unsearchable directories.
1137 (file_directory_p): New function, which uses 'stat' on most platforms
1138 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1139 (Ffile_directory_p, Fset_file_times): Use it.
1140 (file_accessible_directory_p): New function, which uses a single
1141 syscall for efficiency.
1142 (Ffile_accessible_directory_p): Use it.
1143 * xrdb.c (file_p): Use file_directory_p.
1144 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1145 * lread.c (openp): When opening a file, use fstat rather than
1146 stat, as that avoids a permissions race. When not opening a file,
1147 use file_directory_p rather than stat.
1148 (dir_warning): First arg is now a usage string, not a format.
1149 Use errno. All uses changed.
1150 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1151 that merely introduced a race.
1152 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1153 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1154 and similarly for the other O_* flags.
1155 * w32.c (sys_faccessat): Rename from sys_access and switch to
1156 faccessat's API. All uses changed.
1157 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1158 (magic_db): Rename from magic_file_p.
1159 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1160 char *, so that we don't have to test for file existence
1161 separately from opening the file for reading. This removes a race
1162 fixes a permission-checking problem, and simplifies the code.
1164 (file_p): Remove; no longer needed.
1166 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1168 Omit glyphs initialization at startup.
1169 * dispnew.c (glyphs_initialized_initially_p): Remove.
1170 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1171 (Fredraw_frame): Move actual code from here...
1172 (redraw_frame): ...to here. Add eassert. Adjust comment.
1173 (Fredraw_display): Use redraw_frame.
1174 * xdisp.c (clear_garbaged_frames): Likewise.
1176 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1178 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1179 passed to pint2str and pint2hrstr to be at most the size of the
1180 frame's decode_mode_spec_buffer. This avoids crashes with very
1181 large values of FIELD_WIDTH argument to decode_mode_spec.
1184 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1186 Fix a race with verify-visited-file-modtime (Bug#12863).
1187 Since at least 1991 Emacs has ignored an mtime difference of no
1188 more than one second, but my guess is that this was to work around
1189 file system bugs that were fixed long ago. Since the race is
1190 causing problems now, let's remove that code.
1191 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1192 whose time stamp is off by no more than a second. Insist that the
1193 file time stamps match exactly.
1195 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1197 * frame.h (struct frame): Convert external_tool_bar member to
1198 1-bit unsigned bitfield.
1199 * termhooks.h (struct terminal): Remove mouse_moved member since
1200 all users are long dead. Adjust comment on mouse_position_hook.
1202 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1204 Simplify by using FOR_EACH_FRAME here and there.
1205 * frame.c (next_frame, prev_frame, other_visible_frames)
1206 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1207 * w32term.c (x_window_to_scroll_bar): Likewise.
1208 * window.c (window_list): Likewise.
1209 * xdisp.c (x_consider_frame_title): Likewise.
1210 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1211 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1212 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1213 * xmenu.c (menubar_id_to_frame): Likewise.
1214 * xselect.c (frame_for_x_selection): Likewise.
1215 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1216 (x_window_to_menu_bar): Likewise.
1217 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1219 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1221 * data.c (Qdefalias_fset_function): Now static.
1223 Another tweak to vectorlike_header change.
1224 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1225 Remove, and replace all uses with ...
1226 (next_in_free_list, set_next_in_free_list):
1227 New functions, which respect C's aliasing rules better.
1229 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1231 * window.c (list4i): Rename from 'quad'. All uses changed.
1232 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1234 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1236 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1237 warning about mixing declarations and code in ISO C90.
1239 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1241 * window.c (Fsplit_window_internal): Set combination limit of
1242 new parent window to t iff Vwindow_combination_limit is t;
1243 fixing a regression introduced with the change from 2012-09-22.
1244 (Fset_window_combination_limit): Fix doc-string.
1246 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1248 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1249 amount when the scroll margins are too large. When scrolling
1250 backwards in the buffer, give up if cannot reach point or the
1251 scroll margin within a reasonable number of screen lines.
1252 Fixes point position in window under scroll-up/down-aggressively when
1253 point is positioned many lines beyond the window top/bottom.
1256 * ralloc.c (relinquish): If real_morecore fails to return memory
1257 to the system, don't crash; instead, leave the last heap
1258 unchanged and return. (Bug#12774)
1260 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1262 * lisp.h (AUTOLOADP): New macro.
1263 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1264 * data.c (Ffset): Remove special ad-advice-info handling.
1265 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1267 (Finteractive_form): Simplify.
1268 (Fquo): Don't insist on having at least 2 arguments.
1269 (Qdefalias_fset_function): New var.
1271 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1273 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

1279 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1281 Fix recently introduced crash on MS-Windows (Bug#12839).
1282 * w32term.h (struct scroll_bar): Use convenient header.
1283 (SCROLL_BAR_VEC_SIZE): Remove.
1284 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1286 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1288 Tweak last vectorlike_header change.
1289 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1290 vectorlike object on the free list. This is introduced to avoid
1291 some (but not all) pointer casting and aliasing problems, see
1292 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1293 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1295 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1297 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1299 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1300 been removed, so remove them here also.
1302 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1304 * doc.c (Fdocumentation): Handle new property
1305 dynamic-docstring-function to replace the old ad-advice-info.
1307 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1309 * fns.c (Qeql, hashtest_eq): Now static.

1318 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1320 Use same hash function for hashfn_profiler as for hash_string etc.
1321 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1322 * lisp.h (sxhash_combine): New inline function, with the contents
1323 of the old SXHASH_COMBINE.
1324 * profiler.c (hashfn_profiler): Use it, instead of having a
1325 special hash function containing a comparison that always yields 1.
1327 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1329 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1330 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1331 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1334 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1336 * image.c (xpm_make_color_table_h): Fix compiler error because

1346 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1347 (make_log): Use them.

1359 (hash_lookup, hash_remove_from_table): Move assertion checking of
1360 hashfn result here. Check hash-equality before calling cmpfn.

1370 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1372 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1373 value of w32-scroll-lock-modifier is neither nil nor one of the
1374 known key modifiers. (Bug#12806)
1376 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1378 Shrink struct vectorlike_header to the only size field.
1379 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1381 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

1400 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1401 (large_vectors): Change type to struct large_vector.
1402 (allocate_vector_from_block): Simplify.
1403 (PSEUDOVECTOR_NBYTES): Replace with...

1413 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1415 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1416 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1417 (copy_hash_table): Adjust to match vector header change.
1418 * lread.c (defsubr): Use XSETPVECTYPE.
1419 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
1420 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1421 (xvecsize): New command.
1423 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1425 * keyboard.c (event_to_kboard): Do not dereference
1426 frame_or_window field of SELECTION_REQUEST_EVENT
1427 and SELECTION_CLEAR_EVENT events (Bug#12814).
1428 * xterm.h (struct selection_input_event): Adjust comment.
1430 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1432 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1433 such as Scroll Lock, if the respective keys are treated as
1434 function keys, not as modifiers. This avoids destroying non-ASCII
1435 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1437 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1439 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1441 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1443 Restore some duplicate definitions (Bug#12814).
1444 This undoes part of the 2012-11-03 changes. Some people build
1445 with plain -g rather than with -g3, and they need the duplicate
1446 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1447 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1448 Define as macros, as well as as enums or as constants.
1450 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1452 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1453 to keypad keys (Bug#12816).
1455 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1457 Minor adjustments of recently-changed frame functions.
1458 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1459 known to be a frame (we're in the FRAMEP branch).
1460 * lisp.h (Qframep): Remove decl. frame.h declares this.
1461 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1462 since they're meant for Lisp fixnum values.
1464 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1466 * window.c (Fwindow_combination_limit): Revert to the only
1467 required argument and adjust docstring as suggested in
1468 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1469 by Martin Rudalics <rudalics@gmx.at>.
1471 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1473 Widely used frame validity and checking functions.
1474 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1475 * frame.c (decode_live_frame, decode_any_frame): New functions.
1476 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1477 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1478 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1479 (Fframe_pointer_visible_p): Use decode_any_frame.
1480 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
1481 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1482 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1483 (Fframe_focus): Likewise. Allow zero number of arguments.
1485 (frame_buffer_list, frame_buffer_predicate): Remove.
1486 * lisp.h (frame_buffer_predicate): Remove prototype.
1487 * buffer.c (Fother_buffer): Use decode_any_frame.
1488 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1489 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1490 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1491 (Fclose_font, Ffont_info): Use decode_live_frame.
1492 * fontset.c (check_fontset_name): Likewise.
1493 * terminal.c (Fframe_terminal): Likewise.
1494 * w32fns.c (check_x_frame): Likewise.
1495 * window.c (Fminibuffer_window, Fwindow_at)
1496 (Fcurrent_window_configuration): Likewise.
1497 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1498 Likewise. Allow zero number of arguments. Adjust docstring.
1499 * dispnew.c (Fredraw_frame): Likewise.
1500 * xfaces.c (frame_or_selected_frame): Remove.
1501 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1502 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1503 (Fframe_face_alist): Use decode_live_frame.
1504 * xfns.c (check_x_frame): Likewise.
1506 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1508 * window.c (quad): New function.
1509 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1510 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1511 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1512 (Fwindow_line_height): Use it.
1513 (Fwindow_fringes): Use list3.
1514 (Fwindow_scroll_bars): Use list4.
1515 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1516 (Fwindow_combination_limit): Allow zero number of arguments.
1518 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1520 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1522 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1523 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1524 file descriptor 2 for standard error. (Bug#12805)
1526 2012-11-05 Chong Yidong <cyd@gnu.org>
1528 * process.c (wait_reading_process_output): Revert previous change.
1530 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1532 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1533 This removes code that has been obsolete since around 1990.
1534 * callproc.c (Fcall_process):
1536 * process.c (create_process):
1537 * term.c (dissociate_if_controlling_tty):
1538 Assume setsid exists.
1539 * callproc.c (child_setup): Assume setpgid exists and behaves as
1540 per POSIX.1-1988 or later.
1541 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1542 * emacs.c (shut_down_emacs):
1543 * sysdep.c (sys_suspend, init_foreground_group):
1544 Assume getpgrp behaves as per POSIX.1-1998 or later.
1545 * msdos.c (setpgrp): Remove.
1546 (tcgetpgrp, setpgid, setsid): New functions.
1547 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1548 * term.c (no_controlling_tty): Remove; unused.
1549 * w32proc.c (setpgrp): Remove.
1550 (setsid, tcgetpgrp): New functions.
1552 Simplify by assuming __fpending.
1553 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1554 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1555 Do not assume that __fpending's result fits in int.
1557 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1559 Remove EMACS_OUTQSIZE+sleep hack.
1560 * dispnew.c (update_frame_1): Remove hack for terminals slower
1561 than 2400 bps, which throttled Emacs by having it sleep.
1562 This code hasn't worked since at least 2007, when the multi-tty stuff
1563 was added, and anyway those old terminals are long dead.
1564 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1565 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1567 Fix data-loss with --version (Bug#9574).
1568 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1569 as we can't assume that emacs_strerror is initialized, and strerror
1570 is good enough here.
1571 (main): Invoke atexit earlier, to catch earlier instances of
1572 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1574 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1576 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1577 (keyDown): Remap keypad keys to X11 virtual key codes.
1579 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1581 Fix data-loss with --batch (Bug#9574).
1582 * emacs.c: Include <close-stream.h>.
1583 (close_output_streams): New function.
1584 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1585 and handles errors appropriately.
1586 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1589 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1590 The symptom is a diagnostic "GLib-WARNING **: In call to
1591 g_spawn_sync(), exit status of a child process was requested but
1592 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1593 waitpid(), so exit status can't be returned." The diagnostic
1594 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1595 The real bug is a race condition between Emacs and glib: Emacs
1596 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1597 so that glib can't find it. Work around the bug by invoking
1598 waitpid only on subprocesses that Emacs itself creates.
1599 * process.c (create_process, record_child_status_change):
1600 Don't use special value -1 in pid field, as the caller now must
1601 know the pid rather than having the callee infer it.
1602 The inference was sometimes incorrect anyway, due to another race.
1603 (create_process): Set new 'alive' member if child is created.
1604 (process_status_retrieved): New function.
1605 (record_child_status_change): Use it.
1606 Accept negative 1st argument, which means to wait for the
1607 processes that Emacs already knows about. Move special-case code
1608 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1609 processes that have already been waited for, by testing and
1610 clearing new 'alive' member.
1611 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1612 now does this internally.
1613 (handle_child_signal): Let record_child_status_change do all
1614 the work, since we do not want to reap all exited child processes,
1615 only the child processes that Emacs itself created.
1616 * process.h (Lisp_Process): New boolean member 'alive'.
1618 Omit duplicate definitions no longer needed with gcc -g3.
1619 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1620 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1621 Define only as macros. There's no longer any need to also define
1622 these symbols as enums or as constants, since we now assume
1623 gcc -g3 when debugging.
1625 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1627 * lisp.mk: Adjust comments to the fact that term/internal is now
1628 loaded from loadup.el.
1630 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1631 (msdos_fatal_signal): New function.
1632 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1635 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1636 for GCC versions before 4.
1637 (emacs_raise): Define to call msdos_fatal_signal.
1639 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1640 iterator when starting in the middle of a display or overlay
1643 2012-11-03 Chong Yidong <cyd@gnu.org>
1645 * process.c (wait_reading_process_output): Clean up the last
1648 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1650 * process.c (wait_reading_process_output): Avoid a race condition
1651 with SIGIO delivery (Bug#11536).
1653 2012-11-03 Chong Yidong <cyd@gnu.org>
1655 * buffer.c (cursor_type): Untabify docstring.
1657 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1659 * frame.h (struct frame): Drop can_have_scroll_bars member
1660 which is meaningless for a long time. Adjust comments.
1661 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1662 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1664 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1666 * window.c (decode_next_window_args): Update window arg after
1667 calling decode_live_window and so fix crash reported at
1668 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1669 by Juanma Barranquero <lekktu@gmail.com>.
1670 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1671 * font.c (Ffont_at): Likewise.
1673 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1675 * widget.c (resize_cb): New function.
1676 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1677 (EmacsFrameResize): Check if all is up to date before changing frame
1680 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1682 Implement backtrace output for fatal errors on MS-Windows.
1683 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1684 (BACKTRACE_LIMIT_MAX): New macro.
1685 (w32_backtrace): New function.
1686 (emacs_abort): Use w32_backtrace when the user chooses not to
1687 attach a debugger. Update the text of the abort dialog.
1689 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1691 Window-related stuff cleanup here and there.
1692 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1693 Use decode_any_window.
1694 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1695 * xdisp.c (Fformat_mode_line): Likewise.
1696 * font.c (Ffont_at): Use decode_live_window.
1697 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1698 * window.c (decode_next_window_args): Likewise.
1699 (decode_any_window): Remove static.
1700 * window.h (decode_any_window): Add prototype.
1701 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1702 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1705 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1707 Remove pad from struct input_event.
1708 * termhooks.h (struct input_event): Remove padding field.
1710 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1711 member is never cons for a long time. Adjust comment.
1712 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1713 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1714 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1715 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1717 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1719 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1721 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1723 Fix crash when using Emacs as commit editor for git (Bug#12697).
1724 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1725 and it is configured in conf_post.h.
1726 (Fcall_process): Don't invoke both setsid and setpgid; the former
1727 is enough, if it exists.
1728 * callproc.c (Fcall_process, child_setup):
1729 * process.c (create_process): Use setpgid.
1730 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1732 * dispnew.c (init_display): Initialize the foreground group
1733 if we are running a tty display.
1734 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1735 * lisp.h (init_foreground_group): New decl.
1736 * sysdep.c (inherited_pgroup): New static var.
1737 (init_foreground_group, tcsetpgrp_without_stopping)
1738 (narrow_foreground_group, widen_foreground_group): New functions.
1739 (init_sys_modes): Narrow foreground group.
1740 (reset_sys_modes): Widen foreground group.
1742 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1744 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1746 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1748 * minibuf.c (read_minibuf): Restore current buffer since
1749 choose_minibuf_frame calling Fset_frame_selected_window may
1750 change it (Bug#12766).
1752 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1754 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1756 2012-10-30 Kenichi Handa <handa@gnu.org>
1758 * font.c (Ffont_at): If WINDOW is specified and it is not
1759 displaying the current buffer, signal an error.
1761 2012-10-29 Daniel Colascione <dancol@dancol.org>
1763 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1764 In preparation for fixing bug#12739, move these functions from
1767 * coding.h, coding.c: ... to here, and compile them only when
1768 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1769 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1771 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1773 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1774 (timer_loop, getitimer, setitimer): Use it instead of
1775 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1777 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1780 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1782 * nsterm.m (NO_APPDEFINED_DATA): New define.
1783 (last_appdefined_event_data): New variable
1784 (last_appdefined_event): Remove.
1785 (ns_select): Initialize t from last_appdefined_event_data instead
1786 of [last_appdefined_event data1].
1787 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1788 remove last_appdefined_event (Bug#12698).
1790 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1792 * frame.c (x_set_font): Catch internal error.
1794 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1796 Avoid overflow in w32 implementation of interval timers.
1797 When possible, for ITIMER_PROF count only times the main thread
1799 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1800 'volatile ULONGLONG' types. All the other data which was
1801 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1802 (GetThreadTimes_Proc): New typedef.
1803 (w32_get_timer_time): New function, returns a suitable time value
1805 (timer_loop): Enter critical section when accessing ULONGLONG
1806 values of the itimer_data struct, as these accesses are no longer
1807 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1808 Remove unused variable.
1809 (init_timers): Initialize s_pfn_Get_Thread_Times.
1810 (start_timer_thread): Don't assign itimer->caller_thread here.
1811 (getitimer): Assign itimer->caller_thread here.
1812 (setitimer): Always call getitimer to get the value of ticks_now.
1813 (sys_spawnve): Avoid compiler warning about format mismatch.
1815 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1817 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1818 mouse movement events if the menu bar is active. This avoids
1819 producing a busy "hour-glass" cursor by Windows if the mouse
1820 pointer is positioned over a tooltip shown for some menu item.
1822 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1824 Don't assume process IDs fit in int.
1825 * emacs.c (shut_down_emacs) [!DOS_NT]:
1826 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1827 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1828 Use pid_t, not int, to store process IDs, as 'int'
1829 is not wide enough on a few platforms (e.g., AIX and IRIX).
1831 2012-10-23 Kenichi Handa <handa@gnu.org>
1833 The following change is to make face-font-rescale-alist work
1834 correctly for non-ASCII fonts.
1836 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1837 (font_open_for_lface): Handle Vface_font_rescale_alist.
1839 2012-10-23 Chong Yidong <cyd@gnu.org>
1841 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1843 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1845 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1847 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1849 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1852 2012-10-21 Glenn Morris <rgm@gnu.org>
1854 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1856 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1858 Port to OpenBSD 5.1.
1859 * frame.c (Fmouse_position, Fmouse_pixel_position):
1860 * xdisp.c (produce_stretch_glyph):
1861 Declare local vars only when they're needed.
1862 This is clearer and avoids a warning on OpenBSD about unused vars.
1863 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1864 This is safer, and avoids OpenBSD warnings about unused vars.
1865 * keyboard.c (record_menu_key): Remove unnecessary decl.
1866 (poll_timer): Define only if POLL_FOR_INPUT is defined.

2342 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2343 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2344 now a supported configuration.
2346 * Makefile.in: consolidate image variables into LIBIMAGE; add
2347 W32_OBJ and W32_LIBS. Compile new files.
2350 (_DebPrint) declare tracing facility for W32 debugging. We need
2351 to unify tracing later.
2353 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2354 unconditional use of W32 Unicode functions. Cygwin runs only on
2355 100% Unicode operating systems.
2357 * cygw32.c: New file. Define Cygwin-specific facilities.
2358 (Fcygwin_convert_path_to_windows)
2359 (Fcygwin_convert_path_from_windows): New user functions for
2360 accessing Cygwin path-munging routines.
2362 * cygw32.h: New file.
2363 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2364 UTF-16LE strings temporarily inside non-Lisp-visible string
2367 (w32_strerror): Just what it says on the tin.
2369 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2370 also run for Cygwin; both systems have the same problem with using
2371 GUI facilities in a forked child. Also call syms_of_cygw32,
2372 syms_of_w32select in correct places.
2374 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2375 needs fork-then-exec for daemon launching.
2377 * font.h: Include frame.h.
2379 * image.c: Use the image library cache machinery only when we're
2380 compiling for native WINDOWSNT; Cygwin can use shared libraries
2381 like any other Unixlike system.
2383 * keyboard.c: Clarify a comment regarding the input loop.
2385 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2386 functions directly instead of trying to detect at runtime that our
2387 host operating system supports them. We make this change for two
2388 reasons: Cygwin lacks support for the multibyte character
2389 conversion functions used by the legacy menu code, and Cygwin
2390 never needs to rely on non-Unicode APIs.
2392 * unexw32.c (hinst): Declare extern.
2394 * w32.c: Change header order;
2395 (w32_strerror): Move to w32fns.c because we need it for
2396 non-WINDOWSNT builds.
2398 * w32.h: Add #error macro to make sure we don't include w32.h for
2399 Cygwin builds. Remove w32select declarations.
2401 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2402 w32fns.c. w32console.c is WINDOWSNT-only.
2404 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2405 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2407 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2408 (w32_major_version, w32_minor_version, w32_build_number)
2409 (os_subtype, sound_type): Define here
2410 (w32_defined_color): Make color parameter const for consistency
2411 with other _defined_color functions.
2412 (w32_createwindow): Unconditionally call w32_init_class instead of
2413 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2414 through the code is complex and unnecessary because class
2415 registration is practically free.
2416 (w32_name_of_message): New EMACSDEBUG-only function.
2417 (Fset_message_beep): Move here
2418 (Fx_open_connection): Require that the display name for Windows be
2419 "w32" for consistency, emacsclient disambiguation, and maybe, one
2420 day, multi-window-system support.
2421 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2422 Cygwin files for W32 GUI facilities, since these clearly don't
2423 expect Cygwin names.
2424 (_DebPrint): Define.
2425 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2426 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2427 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2428 (w32_last_error): Remove.
2430 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2432 * w32heap.c (syspage_mask): Declare here.
2433 (cache_system_info): Remove.
2435 * w32inevt.c (faked_key): Define globally, not statically.
2436 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2437 (w32_console_toggle_lock_key): Move to w32fns.c.
2439 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2441 * w32proc.c (_DebPrint): Move to w32fns.c.
2442 * w32select.c: Include string.h, stdio.h for Cygwin.
2443 * w32select.h: New File.
2445 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2447 (w32_message_fd): New variable. Under Cygwin, holds the file
2448 descriptor the system used to tell us about pending thread
2451 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2452 that prevented compilation under non-WINDOWSNT systems.
2454 (w32_initialize): Open /dev/windows and assign it to
2455 w32_message_fd. Provide w32 feature.
2457 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2458 (WM_EMACS_INPUT_READY): add.
2459 (prepend_msg, w32_message_fd): Declare globally.
2462 (keyboard_handle): Use only when WINDOWSNT.
2463 (notify_msg_ready): New function. Posts a message to the main
2464 thread's message queue under CYGWIN, which wakes up the main
2465 thread from select(2) by making the /dev/windows file descriptor
2466 ready. Under WINDOWSNT, it sets an event the same way the old
2469 (post, prepend_msg): Actually call notify_msg_ready instead of
2470 setting the input event directly.
2472 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2474 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2475 but it still has blocs in it, don't return it to the system,
2476 instead of aborting. (Bug#12402)
2478 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2480 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2482 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2483 MAC_OS_X_VERSION_10_6.
2484 (syms_of_nsterm): Remove comment about Panther and above for
2486 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2487 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2488 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2490 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2491 MAC_OS_X_VERSION_10_4.
2493 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2494 MAC_OS_X_VERSION_10_2.
2496 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2498 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2499 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2501 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2502 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2503 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2504 Remove ns_in_resize check.
2505 (ns_clear_frame_area): Remove resize handle code.
2507 * nsfns.m (ns_in_resize): Remove.
2508 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2509 Remove ns_in_resize check.
2511 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2513 Improve sys_siglist detection.
2514 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2515 defined as a macro, as is done in Solaris.
2516 (sys_siglist_entries): New macro.
2517 (save_strsignal): Use it.
2518 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2519 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2521 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2523 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2524 fullscreen/Fullscreen.
2526 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2527 tobar_height is new.
2529 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2530 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2531 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2532 (windowDidResize:): Check for correct window if old style fullscreen.
2533 Capitalize word in comment. Remove incorrect comment.
2534 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2535 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2536 error in drawing background.
2537 (toggleFullScreen:): Remove comment. Rearrange calls.
2538 Set toolbar values to zero, save old height in tobar_height.
2539 Restore tool bar height when leaving fullscreen.
2540 (canBecomeMainWindow): New function.
2542 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2544 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2546 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2548 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2550 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2551 that time stamps of directories could also be changed.
2552 Don't request the too broad GENERIC_WRITE, only the more restrictive
2553 FILE_WRITE_ATTRIBUTES access rights.
2555 * fileio.c (Fset_file_times): Special-case ignoring errors for
2556 directories only on MSDOS, not on MS-Windows.
2558 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2560 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2562 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2564 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2565 see whether CreateFile failed.
2567 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2569 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2570 to avoid similar races.
2571 * keyboard.c (pending_signals): Now bool, not int.
2573 Port timers to OpenBSD, plus check for timer failures.
2574 OpenBSD problem reported by Han Boetes.
2575 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2577 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2578 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2579 like OpenBSD, which has timer_settime but does not declare it.
2580 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2581 whether to use itimerspec-related primitives. All uses of
2582 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2584 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2586 * profiler.c (handle_profiler_signal): Fix a malloc race
2587 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2589 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2591 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2593 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2595 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2596 consistent with the change in return value of 'safe_strsignal'.
2598 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2600 Prefer plain 'static' to 'static inline' (Bug#12541).
2601 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2602 (bidi_set_sor_type, bidi_push_embedding_level)
2603 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2604 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2605 (bidi_cache_search, bidi_cache_ensure_space)
2606 (bidi_cache_iterator_state, bidi_cache_find)
2607 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2608 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2609 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2610 Now 'static', not 'static inline'.
2612 Count overruns when profiling; change units to ns.
2613 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2614 Give extra weight to samples after overruns, to attempt to count
2615 the time more accurately.
2616 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2617 the underlying primitives nominally do ns.
2618 (Fprofiler_cpu_start): Document the change. Mention that
2619 the sampling intervals are only approximate.
2621 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2623 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2625 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2626 case for the special 0 coding-system.
2628 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2629 (Fmake_overlay): Remove redundant tests.
2630 (fix_start_end_in_overlays): Remove redundant recentering.
2632 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2634 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2635 Update dependencies.
2637 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2639 Fix a malloc race condition involving strsignal.
2640 A signal can arrive in the middle of a malloc, and Emacs's signal
2641 handler can invoke strsignal, which can invoke malloc, which is
2642 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2643 Fix it by altering the signal handler so that it does not invoke
2645 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2646 * process.c (status_message): Use const pointer, in case strsignal
2647 is #defined to safe_strsignal.
2648 * sysdep.c (sys_siglist, init_signals): Always define and
2649 initialize a substitute sys_siglist if the system does not define
2650 one, even if HAVE_STRSIGNAL.
2651 (safe_strsignal): Rename from strsignal. Always define,
2652 using sys_siglist. Return a const pointer.
2653 * syssignal.h (safe_strsignal): New decl.
2654 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2656 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2658 * w32proc.c (timer_loop): Fix code that waits for timer
2659 expiration, to avoid high CPU usage.
2661 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2663 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2664 (sweep_weak_table): Remove redundant prototypes.
2666 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2668 * emacs.c: Move the inclusion of TERM_HEADER after including
2669 windows.h on WINDOWSNT. This avoids compilation problems with
2672 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2674 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2675 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2676 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2677 as the previous version used 'void *'.
2679 * ralloc.c (ROUNDUP): Fix last change.
2680 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2683 * w32proc.c <disable_itimers>: New static flag.
2684 (init_timers): Initialize it to zero, after creating the critical
2685 sections used by the timer threads.
2686 (term_timers): Set to 1 before deleting the critical sections.
2687 (getitimer, setitimer): If disable_itimers is non-zero, return an
2688 error indication without doing anything. Reported by Fabrice
2689 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2690 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2692 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2695 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2696 term_ntproc after all the other bookkeeping, to get timers working
2697 as long as possible.
2699 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2701 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2702 Suggested by Juri Linkov in
2703 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2705 Prefer plain 'static' to 'static inline' (Bug#12541).
2706 With static functions, modern compilers inline pretty well by
2707 themselves; advice from programmers often hurts as much as it helps.
2708 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2709 this change shrinks the text size of the Emacs executable by 1.1%
2710 without affecting CPU significantly in my benchmark.

3004 (handle_profiler_signal): Rename from sigprof_handler_1,
3005 for consistency with other handlers. Do not check whether
3006 cpu_log is a hash-table if garbage collecting, since it

3009 for consistency with other handlers.
3010 (setup_cpu_timer): New function, with much of what used to be in

3012 Prefer timer_settime if available, and prefer
3013 thread cputime clocks, then process cputime clocks, then
3014 monotonic clocks, to the old realtime clock. Use make_timeval
3015 to round more-correctly when falling back to setitimer.
3016 (Fprofiler_cpu_start): Use it.
3017 (Fprofiler_cpu_stop): Prefer timer_settime if available.

3287 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3289 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3290 fatal_error_backtrace.
3292 * w32proc.c (sys_kill): Undo last change: don't do anything when
3293 invoked to deliver SIGABRT to our own process. This is now
3294 handled by emacs_raise.
3296 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3298 * w32term.c (w32_read_socket): Remove leftover reference to
3299 interrupt_input_pending.
3301 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3303 Do not use SA_NODEFER.
3304 Problem reported by Dani Moncayo in
3305 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3307 * sysdep.c (emacs_abort): Do not reset signal handler.
3308 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3309 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3310 wanted even on POSIXish hosts, and it doesn't work on Windows.
3312 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3314 * xterm.c (x_term_init): Call fixup_locale before and after calling
3315 gtk_init (Bug#12392).
3317 2012-09-23 Chong Yidong <cyd@gnu.org>
3319 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3320 Vdynamic_library_alist.
3322 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3323 (Fgnutls_available_p): Caller changed.
3325 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3326 (Flibxml_parse_xml_region): Likewise.
3328 * dispextern.h (struct image_type): Remove arg from init function.
3330 * image.c (Finit_image_library, lookup_image_type)
3331 (define_image_type): Remove now-unneeded second arg.
3332 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3333 (init_tiff_functions, init_gif_functions, init_svg_functions):
3334 Arglist and w32_delayed_load calling convention changed.
3335 (gs_type): Remove init_gs_functions; there is no such function.
3336 (valid_image_p, make_image): Fix caller to lookup_image_type.
3338 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3340 Simplify and avoid signal-handling races (Bug#12471).
3342 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3343 Avoid recursive loop if there's a fatal error in the function itself.
3344 * atimer.c (pending_atimers):
3345 * blockinput.h: Don't include "atimer.h"; no longer needed.
3346 (interrupt_input_pending): Remove. All uses removed.
3347 pending_signals now counts both atimers and ordinary interrupts.
3348 This is less racy than having three separate pending-signal flags.
3349 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3351 Rename from their upper-case counterparts BLOCK_INPUT,
3352 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3353 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3354 This makes it easier to access volatile variables more accurately.
3355 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3356 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3357 that's more reliable if the code is buggy and sets
3358 interrupt_input_blocked to a negative value. All uses changed.
3359 * atimer.c (deliver_alarm_signal):
3360 Remove. No need to deliver this to the parent; any thread can
3361 handle this signal now. All uses replaced by underlying handler.
3362 * atimer.c (turn_on_atimers):
3363 * dispnew.c (handle_window_change_signal):
3364 * emacs.c (handle_danger_signal):
3365 * keyboard.c (kbd_buffer_get_event):
3366 Don't reestablish signal handler; not needed with sigaction.
3367 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3369 Rework to avoid unnecessary accesses to volatile variables.
3370 (UNBLOCK_INPUT_TO): Now a function.
3371 (totally_unblock_input, unblock_input): New decls.
3372 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3373 (init_data): Remove. Necessary stuff now done in init_signal.
3374 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3375 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3376 (fatal_error_code): Remove; no longer needed.
3377 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3378 it doesn't always backtrace. All uses changed. No need to reset
3379 signal to default, since sigaction and/or die does that for us now.
3380 Use emacs_raise (FOO), not kill (getpid (), FOO).
3381 (main): Check more-accurately whether we're dumping.
3382 Move fatal-error setup to sysdep.c
3383 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3384 * gtkutil.c (xg_get_file_name, xg_get_font):
3385 Remove no-longer-needed signal-mask manipulation.
3386 * keyboard.c, process.c (POLL_FOR_INPUT):
3387 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3388 * keyboard.c (read_avail_input): Remove.
3389 All uses replaced by gobble_input.
3390 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3391 (kbd_buffer_store_event_hold, gobble_input):
3392 (record_asynch_buffer_change) [USABLE_SIGIO]:
3393 (store_user_signal_events):
3394 No need to mess with signal mask.
3395 (gobble_input): If blocking input and there are terminals, simply
3396 set pending_signals to 1 and return. All hooks changed to not
3397 worry about whether input is blocked.
3398 (process_pending_signals): Clear pending_signals before processing
3399 them, in case a signal comes in while we're processing.
3400 By convention callers now test pending_signals before calling us.
3401 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3402 New functions, to support changes to blockinput.h.
3403 (handle_input_available_signal): Now extern.
3404 (reinvoke_input_signal): Remove. All uses replaced by
3406 (quit_count): Now volatile, since a signal handler uses it.
3407 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3408 All callers changed. Block SIGINT only if not already blocked.
3409 Clear sigmask reliably, even if Fsignal returns, which it can.
3410 Omit unnecessary accesses to volatile var.
3411 (quit_throw_to_read_char): No need to restore sigmask.
3412 * keyboard.c (gobble_input, handle_user_signal):
3413 * process.c (wait_reading_process_output):
3414 Call signal-handling code rather than killing ourselves.
3415 * lisp.h: Include <float.h>, for...
3416 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3417 (pending_signals): Now volatile.
3418 (syms_of_data): Now const if IEEE floating point.
3419 (handle_input_available_signal) [USABLE_SIGIO]:
3420 (terminate_due_to_signal, record_child_status_change): New decls.
3421 * process.c (create_process): Avoid disaster if memory is exhausted
3422 while we're processing a vfork, by tightening the critical section
3424 (send_process_frame, process_sent_to, handle_pipe_signal)
3425 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3427 (send_process): No need for setjmp/longjmp any more, since the
3428 SIGPIPE stuff is now gone. Instead, report an error if errno
3430 (record_child_status_change): Now extern. PID and W are now args.
3431 Return void, not bool. All callers changed.
3432 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3433 Remove. All uses removed. This bug should be fixed now in a
3435 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3436 and record the child status change directly. This avoids the
3437 need to futz with the signal mask.
3438 (process_fatal_action): Move here from emacs.c.
3439 (emacs_sigaction_flags): New function, containing
3440 much of what used to be in emacs_sigaction_init.
3441 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3442 caught by emacs, to make races less likely.
3443 (deliver_process_signal): Rename from handle_on_main_thread.
3445 (BACKTRACE_LIMIT_MAX): Now at top level.
3446 (thread_backtrace_buffer, threadback_backtrace_pointers):
3448 (deliver_thread_signal, deliver_fatal_thread_signal):
3449 New functions, for more-accurate delivery of thread-specific signals.
3450 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3451 (deliver_arith_signal): Handle in this thread, not
3452 in the main thread, since it's triggered by this thread.
3453 (maybe_fatal_sig): New function.
3454 (init_signals): New arg DUMPING so that we can be more accurate
3455 about whether we're dumping. Caller changed.
3456 Treat thread-specific signals differently from process-general signals.
3457 Block all signals while handling fatal error; that's safer.
3458 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3460 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3461 Ignore SIGPIPE unless batch.
3462 (emacs_backtrace): Output backtrace for the appropriate thread,
3463 which is not necessarily the main thread.
3464 * syssignal.h: Include <stdbool.h>.
3465 (emacs_raise): New macro.
3466 * xterm.c (x_connection_signal): Remove; no longer needed
3467 now that we use sigaction.
3468 (x_connection_closed): No need to mess with sigmask now.
3469 (x_initialize): No need to reset SIGPIPE handler here, since
3470 init_signals does this for us now.
3472 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3474 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3475 background rect may be larger (Bug#12245).
3477 2012-09-23 Chong Yidong <cyd@gnu.org>
3479 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3481 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3483 * .gdbinit: Just stop at fatal_error_backtrace.
3484 See Stefan Monnier's request in
3485 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3486 Remove no-longer-used query of system type.
3488 2012-09-22 Chong Yidong <cyd@gnu.org>
3490 * search.c (Freplace_match): Doc fix (Bug#12325).
3492 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3494 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3495 (Fline_end_position): Doc fix.
3497 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3499 2012-09-22 Chong Yidong <cyd@gnu.org>
3501 * dispextern.h (struct image_type): Add new slot, storing a type
3502 initialization function.
3504 * image.c (define_image_type): Call the image initializer function
3505 if it is defined. Arguments and return value changed.
3506 (valid_image_p, make_image): Callers changed.
3507 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3508 (gif_type, imagemagick_type, svg_type, gs_type):
3509 Add initialization functions.
3510 (Finit_image_library): Call lookup_image_type.
3511 (CHECK_LIB_AVAILABLE): Macro deleted.
3512 (lookup_image_type): Call define_image_type here, rather than via
3513 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3514 (syms_of_image): Move define_image_type calls for xbm_type and
3515 pbm_type to lookup_image_type.
3517 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3519 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3520 'idle_timers' from here ...
3521 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3522 lists, to avoid infloops when the timer does something stupid,
3523 like reinvoke itself with the same or smaller time-out.
3526 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3528 * window.c (Fsplit_window_internal): Handle only Qt value of
3529 Vwindow_combination_limit separately.
3530 (Qtemp_buffer_resize): New symbol.
3531 (Vwindow_combination_limit): New default value.
3534 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3536 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3537 the new overlay string. (Bug#10159)
3539 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3541 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3542 or that fprintf is async-signal-safe. POSIX doesn't require
3545 2012-09-22 Chong Yidong <cyd@gnu.org>
3547 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3550 2012-09-22 Kenichi Handa <handa@gnu.org>
3552 * composite.c (composition_reseat_it): Handle the case that a
3553 grapheme cluster is not covered by a single font (Bug#12352).
3555 2012-09-21 Chong Yidong <cyd@gnu.org>
3557 * image.c (define_image_type): Avoid adding duplicate types to
3558 image_types (Bug#12463). Suggested by Jörg Walter.
3560 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3562 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3563 (print_load_command_name): Add case LC_DATA_IN_CODE.
3564 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3566 2012-09-21 Glenn Morris <rgm@gnu.org>
3568 * eval.c (Frun_hook_with_args_until_success)
3569 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3571 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3573 * fileio.c (Ffile_selinux_context): Only call freecon when
3574 lgetfilecon succeeded.
3575 (Fset_file_selinux_context): Likewise. (Bug#12444)
3577 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3579 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3580 reordering, locate the cursor by calling set_cursor_from_row; if
3581 that fails, clear the desired glyph matrix before returning a
3582 failure indication to the caller. Fixes leaving garbled display
3583 when fast scrolling with a down-key. (Bug#12403)
3584 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3585 scrolling through multibyte text.
3587 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3589 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3590 calling mark_vectorlike since that's the one that marks the window.
3591 (mark_discard_killed_buffers): Mark the final cdr.
3592 * window.h (struct window): Move prev/next_buffers to the
3593 non-standard fields.
3594 * window.c (make_window): Initialize prev/next_buffers manually.
3596 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3598 Omit unused arg EXPECTED from socket hooks.
3599 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3600 * nsterm.m (ns_term_init):
3601 * termhooks.h (struct terminal.read_socket_hook):
3602 * w32inevt.c (w32_console_read_socket):
3603 * w32term.c (w32_read_socket):
3604 * xterm.c (XTread_socket):
3605 Omit unused arg EXPECTED. All callers changed.
3606 (store_user_signal_events): Return void, not int, since callers no
3607 longer care about the return value. All uses changed.
3609 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3611 * w32gui.h (XParseGeometry): Do not declare.
3613 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3615 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3616 Ignore 'expected'. See Eli Zaretskii in
3617 <http://bugs.gnu.org/12471#8> (last line).
3619 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3620 (XParseGeometry): Now static. Substitute extremal values for
3621 values that are out of range.
3623 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3625 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3627 * nsfns.m (XParseGeometry): Remove.
3628 (Fx_create_frame): Call x_set_offset to correctly interpret
3629 top_pos in geometry.
3631 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3632 (Fx_parse_geometry): If there is a space in string, call
3633 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3635 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3637 * search.c (scan_buffer): Use character positions in calls to
3638 region_cache_forward and region_cache_backward, not byte
3639 positions. (Bug#12196)
3641 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3642 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3644 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3645 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3646 emacs_blocked_malloc, now deleted.
3648 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3650 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3651 The workaround was for improving performance on Solaris 2.4, but
3652 is getting in the way now. Emacs will still work if someone is
3653 still running Solaris 2.4 in a museum somewhere; Sun dropped
3654 support for Solaris 2.4 in 2003.
3655 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3656 * process.c (create_process) [HAVE_WORKING_VFORK]:
3657 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3658 since Emacs no longer uses vfork on that platform.
3660 2012-09-17 Glenn Morris <rgm@gnu.org>
3662 * emacs.c: Use COPYRIGHT.
3664 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3666 Remove configure's --without-sync-input option (Bug#12450).
3667 When auditing signal-handling in preparation for cleaning it up,
3668 I found that SYNC_INPUT has race conditions and would be a real
3669 pain to fix. Since it's an undocumented and deprecated
3670 configure-time option, now seems like a good time to remove it.
3671 Also see <http://bugs.gnu.org/11080#16>.
3672 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3673 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3674 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3675 (malloc_hysteresis):
3676 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3677 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):

3681 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3682 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3683 Remove. All uses removed.
3684 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3685 implementation, one that depends on whether the new macro
3686 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3688 * atimer.c (run_timers, handle_alarm_signal):
3689 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3690 (handle_async_input, process_pending_signals)

3700 * eval.c (handling_signal): Remove. All uses removed.
3701 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3702 All uses replaced with the SYNC_INPUT version.
3703 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3705 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3708 * font.c (Ffont_shape_gstring): Remove unused local.
3710 2012-09-16 Glenn Morris <rgm@gnu.org>
3712 * Makefile.in (clean): No longer run nextstep's clean.
3714 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3716 (ns-app): Move here from ns.mk, and simplify.
3717 (clean): Simplify nextstep entry.
3718 * ns.mk: Remove file.
3720 2012-09-17 Kenichi Handa <handa@gnu.org>
3722 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3723 not covert the last few charactes.
3725 2012-09-16 Kenichi Handa <handa@gnu.org>
3727 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3728 here, but just check the validity of glyphs in the glyph-string.
3730 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3732 * window.c (Fwindow_parameter, Fset_window_parameter):
3733 Accept any window as argument (Bug#12452).
3735 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3737 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3738 to ns_term_init to avoid memory leak.
3740 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3741 explicit retain/release.
3742 (ns_term_init): Only allow one display. Initialize outerpool and
3745 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3747 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3748 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3749 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3750 the Microsoft problem in a different way, by altering ../nt/config.nt.
3752 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3767 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3768 by lisp.h. This completes removal of setjmp.h inclusion
3769 erroneously announced in the previous commit. (Bug#12446)
3771 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3774 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3775 not defined as a macro. The latter happens on MS-Windows.
3778 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3780 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3781 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3782 Some instances of '#include <setjmp.h>' removed, if the
3783 only reason for the instance was because "lisp.h" was included.
3784 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3785 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3786 and _longjmp with the new symbols. Emacs already uses _setjmp if
3787 available, so this change affects only POSIXish hosts that have
3788 sigsetjmp but not _setjmp, such as some versions of Solaris and
3789 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3790 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3791 (png_load_body) [HAVE_PNG]:
3792 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3793 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3794 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3795 since PNG requires jmp_buf. This is the only exception to the
3796 general rule that we now use sys_setjmp and sys_longjmp.
3797 This exception is OK since this code does not change the signal
3798 mask or longjmp out of a signal handler.
3800 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3802 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3803 Include "syssignal.h", for 'main_thread'.
3805 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3807 Avoid out-of-range marker position (Bug#12426).
3808 * insdel.c (replace_range, replace_range_2):
3809 Adjust markers before overlays, as suggested by comments.
3810 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3811 Remove redundant check before calling offset_intervals.
3813 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3815 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3816 current buffer (Bug#12387).
3818 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3820 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3822 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3824 Use a more backwards-compatible timer format (Bug#12430).
3825 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3826 vector element, not from the 4th, since PSECS is now at the end.
3827 (Fcurrent_idle_time): Doc fix.
3829 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3831 Function to mark objects and remove killed buffers at once.
3832 * alloc.c (discard_killed_buffers): Rename to ...
3833 (mark_discard_killed buffers) ... new name. Add marking
3834 of remaining objects. Fix comment. Adjust users.
3835 (mark_object): Do not touch frame buffer lists here.
3836 * frame.c (delete_frame): Reset frame buffer lists here.
3838 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3840 Better workaround for GNOME bug when --enable-gcc-warnings.
3841 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3842 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3843 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3845 Simplify SIGIO usage (Bug#12408).
3846 The code that dealt with SIGIO was crufty and confusing, e.g., it
3847 played tricks like "#undef SIGIO" but these tricks were not used
3848 consistently. Simplify mostly by not #undeffing standard symbols,
3849 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3850 or not as we please) rather than "defined SIGIO" (standard symbol
3851 that we probably shouldn't #undef).
3852 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3853 Modules that need it can include it.
3854 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3855 * dispextern.h (ignore_sigio): New decl.
3856 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3857 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3858 * emacs.c (shut_down_emacs):
3859 * keyboard.c (kbd_buffer_store_event_hold):
3860 Use ignore_sigio rather than invoking 'signal' directly.
3861 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3863 (FIONREAD, SIGIO): Do not #undef.
3864 (tty_read_avail_input): Use #error rather than a syntax error.
3865 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3866 for I_PIPE, used by SETUP_SLAVE_PTY.
3867 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3868 * sysdep.c (croak): Remove; no longer needed. This bit of
3869 temporary code, with Fred N. Fish's comment that it's temporary,
3870 has been in Emacs since at least 1992!
3871 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3872 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3873 * syssignal.h (croak): Remove decl.
3874 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3875 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3876 now that we're termios-only.
3877 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3878 * term.c (dissociate_if_controlling_tty): Use #error rather than
3881 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3882 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3883 to work around GNOME bug 683906.
3884 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3885 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3886 This works around GCC bug 54561.
3888 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3890 More fixes for 'volatile' and setjmp/longjmp.
3891 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3892 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3893 (png_load_body) [HAVE_PNG]:
3894 (jpeg_load_body) [HAVE_JPEG]:
3895 New function, with most of the old parent function's body.
3896 (png_load) [HAVE_PNG]:
3897 (jpeg_load) [HAVE_JPEG]:
3898 Invoke the new function, to avoid longjmp munging our locals.
3899 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3900 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3901 longjmp is passed 2, as the C standard doesn't guarantee this.
3902 Instead, store the failure code into mgr->failure_code.
3904 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3906 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3907 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3908 (syms_of_keyboard): Remove support for unread-command-char.
3910 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3912 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3913 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3914 violation. (Bug#12426)
3916 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3918 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3920 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3922 * eval.c: Add `inhibit-debugger'.
3923 (Qinhibit_debugger): New symbol.
3924 (call_debugger): Bind it instead of Qdebug_on_error.
3925 (maybe_call_debugger): Test Vinhibit_debugger.
3926 (syms_of_eval): Define inhibit-debugger.
3927 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3928 (syms_of_xdisp): Remove inhibit-debug-on-message.
3930 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3932 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3933 If a nonvolatile local variable is written before a _longjmp to
3934 the frame containing the variable, and is read after the _longjmp,
3935 the value read is indeterminate. Some local variables of type
3936 'struct handler' and 'struct catchtag' are used in this way, so
3937 mark each of their slots as volatile if the slot can be set before
3938 _longjmp and read afterwards.
3939 * lisp.h (struct handler): var and chosen_clause are now volatile.
3940 (struct catchtag): val, next, and pdlcount are now volatile.
3942 * bidi.c (bidi_push_it, bidi_pop_it):
3943 * fns.c (copy_hash_table):
3944 * image.c (define_image_type):
3945 * keyboard.c (kbd_buffer_store_event_hold):
3946 * process.c (Fprocess_send_eof):
3947 * xfaces.c (x_create_gc) [HAVE_NS]:
3948 * xgselect.c (xg_select):
3949 Prefer assignment to memcpy when either will do.
3951 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3952 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3953 time an item is removed. No need to mark this function 'inline';
3954 the compiler knows better than we do.
3956 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3958 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3959 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3960 to change_frame_size (Bug#12388).
3961 (windowDidResize:): Pass YES to updateFrameSize.
3963 * nsterm.h: Add delay parameter to updateFrameSize.
3965 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3967 Discard killed buffers from deleted window and frame objects.
3968 This reduces an amount of references to killed buffers and
3969 helps GC to reclaim them faster.
3970 * alloc.c (discard_killed_buffers): New function.
3971 (mark_object): Use it for deleted windows and frames.
3972 (mark_object): If symbol's value is set up for a killed buffer
3973 or deleted frame, restore its global binding.
3974 * data.c (swap_in_global_binding): Add GC notice.
3975 (swap_in_symval_forwarding): Use convenient set_blv_where.
3976 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3977 * window.h: ... to here.
3979 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3981 Convenient macro to check whether the buffer is live.
3982 * buffer.h (BUFFER_LIVE_P): New macro.
3983 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3984 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3986 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3988 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3989 composition cases (Bug#12364).
3991 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3992 overhang of succeeding glyphs overlapping box cursor.
3994 * w32term.c (x_draw_glyph_string): Likewise.
3996 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3998 Simplify, document, and port floating-point (Bug#12381).
3999 The porting part of this patch fixes bugs on non-IEEE platforms
4000 with frexp, ldexp, logb.
4001 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4003 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4004 support, by removing commented-out code and briefly listing the
4005 C89 functions excluded. The commented-out stuff was confusing
4006 maintenance, e.g., we thought we needed cbrt but it was commented out.
4007 (logb): Remove decl; no longer needed.
4008 (isfinite): New macro, if not already supplied.
4009 (isnan): Don't replace any existing macro.
4010 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4011 are present on all C89 platforms.
4012 (Ffrexp): Do not special-case zero, as frexp does the right thing
4014 (Flogb): Do not use logb, as it doesn't have the desired meaning
4015 on hosts that use non-base-2 floating point. Instead, stick with
4016 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4017 frexp, to avoid getting an unspecified result.
4019 * xdisp.c (Qinhibit_debug_on_message): Now static.
4021 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4023 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4024 NSBezierPath (Bug#12131).
4026 2012-09-10 Chong Yidong <cyd@gnu.org>
4028 * fns.c (Fdelq, Fdelete): Doc fix.
4030 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4032 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4033 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4035 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4037 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4038 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4041 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4043 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4044 left fringe if the window has a left margin. This avoids leaving
4045 traces of the cursor because its leftmost pixel is not drawn over.
4047 * dispnew.c (update_window_line): When the left margin area of a
4048 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4049 that screen line. (Bug#12277)
4051 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4053 Assume C89 or later for math functions (Bug#12381).
4054 This simplifies the code, and makes it a bit smaller and faster,
4055 and (most important) makes it easier to clean up signal handling
4056 since we can stop worring about floating-point exceptions in
4057 library code. That was a problem before C89, but the problem
4058 went away many years ago on all practical Emacs targets.
4059 * data.c, image.c, lread.c, print.c:
4060 Don't include <math.h>; no longer needed.
4061 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4062 might be autoconfigured, as that never happens.
4064 * doprnt.c (DBL_MAX_10_EXP):
4065 * print.c (DBL_DIG):
4066 Remove. C89 or later always defines these.
4067 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4068 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4069 (arith_error, domain_error, domain_error2):
4070 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4071 no longer needed -- we simply return what C returns. All uses removed.
4072 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4074 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4075 Remove. All uses expanded, as these macros are no longer used
4076 more than once and are now more trouble than they're worth.
4077 (Ftan): Use tan, not sin / cos.
4078 (Flogb): Assume C89 frexp.
4079 (fmod_float): Assume C89 fmod.
4080 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4081 (init_floatfns): Remove. All uses removed.
4083 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4085 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4086 compositeToPoint for OSX < 10.6 (Bug#12390).
4088 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4090 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4091 This produces more-accurate results.
4093 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4095 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4096 changes (Bug#12088).
4098 2012-09-08 Chong Yidong <cyd@gnu.org>
4100 * syntax.c (Fstring_to_syntax): Doc fix.
4102 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4104 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4105 in the internal border.
4106 (x_set_window_size): Remove static variables and their usage.
4107 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4108 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4109 Remove fringe/internal border adjustment (Bug#11052).
4110 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4111 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4112 (ns_fix_rect_ibw): Remove.
4113 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4114 (ns_dumpglyphs_box_or_relief): Ditto.
4115 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4117 (ns_dumpglyphs_image): Ditto.
4118 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4120 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4121 their usage. Add fringe_extended_p and its use as in other terms.
4122 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4123 scroll bar was removed.
4124 (updateFrameSize): New function.
4125 (windowDidResize): Move code to updateFrameSize and call it.
4127 * nsterm.h (EmacsView): Add updateFrameSize.
4129 2012-09-07 Chong Yidong <cyd@gnu.org>
4131 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4133 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4135 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4137 More signal-handler cleanup (Bug#12327).
4138 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4139 Problem introduced when merging patches. Noted by Eli Zaretskii in
4140 <http://bugs.gnu.org/12327#67>.
4141 * floatfns.c: Comment fix.
4142 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4143 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4144 and anyway the declaration is harmless even if SIGDANGER is not defined.
4145 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4146 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4147 source files not surprisingly expected syssignal.h to define, or
4148 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4149 Include <sys/ioctl.h>, for FIONREAD.
4150 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4151 This eliminates a problem whereby other files mysteriously had
4152 to include "syssignal.h" before including "systty.h" if they
4153 wanted to use "#ifdef SIGIO".
4155 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4157 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4159 * w32.c (sigemptyset): Empty the set.
4160 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4162 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4164 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4166 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4167 (mark_object): Likewise for frame objects.
4169 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4171 * syssignal.h (handle_on_main_thread): Always declare,
4172 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4173 This ports to platforms without HAVE_PTHREAD.
4175 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4177 Signal-handler cleanup (Bug#12327).
4178 Emacs's signal handlers were written in the old 4.2BSD style with
4179 sigblock and sigmask and so forth, and this led to some
4180 inefficiencies and confusion. Rewrite these to use
4181 pthread_sigmask etc. without copying signal sets around. Also,
4182 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4183 'signal', and instead use functions that do not attempt to take
4184 over the system name space. This patch causes Emacs's text
4185 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4186 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4187 Do not include <signal.h> or "syssignal.h", as these
4188 modules do not use signals.
4189 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4190 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4191 Do not include <signal.h>, as "syssignal.h" does that for us now.
4192 * atimer.c (sigmask_atimers): New function.
4193 (block_atimers, unblock_atimers): New functions,
4194 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4196 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4197 no longer needed here.
4198 * emacs.c (main): Inspect existing signal handler with sigaction,
4199 so that there's no need to block and unblock SIGHUP.
4200 * sysdep.c (struct save_signal): New member 'action', replacing
4201 old member 'handler'.
4202 (save_signal_handlers, restore_signal_handlers):
4203 Use sigaction instead of 'signal' to save and restore.
4204 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4205 New function. All users of 'signal' modified to use set_sighandler
4206 if they're writeonly, and to use sys_signal if they're read+write.
4207 (emacs_sigaction_init, forwarded_signal): New functions.
4208 (sys_signal): Remove. All uses replaced by calls to sigaction
4209 and emacs_sigaction_init, or by direct calls to 'signal'.
4210 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4211 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4212 all uses replaced by pthread_sigmask etc. calls.
4213 * syssignal.h: Include <signal.h>.
4214 (emacs_sigaction_init, forwarded_signal): New decls.
4215 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4216 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4217 (sigmask, sys_sigmask): Remove; no longer needed.
4218 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4219 (sigblock, sigunblock, sigfree):
4220 (sigsetmask) [!defined sigsetmask]:
4221 Remove. All uses replaced by pthread_sigmask.
4222 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4223 no longer need to be replaced, and its typical old uses
4224 are now done via emacs_sigaction_init and sigaction.
4225 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4226 (sys_sigdel): Remove; unused.
4227 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4229 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4231 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4232 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4234 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4236 Explicitly mark buffer_defaults and buffer_local_symbols.
4237 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4238 mark_local_symbols here.
4239 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4240 since special buffers aren't marked here any more.
4241 (allocate_buffer): Chain new buffer with all_buffers here...
4242 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4244 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4245 (syms_of_buffer): Remove staticpro of the above.
4246 (init_buffer_once): Set names for buffer_defaults and
4247 buffer_local_symbols.
4249 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4251 Use bool for booleans in font-related modules.
4252 * font.c (font_intern_prop, font_style_to_value)
4253 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4254 (generate_otf_features, font_check_otf_features, font_check_otf)
4255 (font_match_p, font_list_entities, font_at):
4256 * fontset.c (fontset_id_valid_p, reorder_font_vector
4257 (fontset_find_font, Fset_fontset_font)
4258 (face_suitable_for_char_p) [0]:
4259 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4260 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4261 (m17n_flt_initialized, ftfont_shape_by_flt):
4262 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4263 * nsfont.m (nsfont_draw):
4264 * w32font.c (w32font_draw):
4265 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4266 Use bool for booleans.
4267 * font.h: Adjust to above API changes.
4268 (struct font, struct font_driver, struct font_driver_list):
4269 Use bool for booleans.
4270 (struct font): Remove useless member encoding_type.
4272 * fontset.c, xftfont.c: Omit unnecessary static decls.
4274 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4276 * alloc.c (mark_object): Revert window marking code
4277 since it's unsafe for the Fset_window_configuration.
4279 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4281 Fix race conditions with signal handlers and errno (Bug#12327).
4282 Be more systematic about preserving errno whenever a signal
4283 handler returns, even if it's not in the main thread. Do this by
4284 renaming signal handlers to distinguish between signal delivery
4285 and signal handling. All uses changed.
4286 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4287 * data.c (deliver_arith_signal): Rename from arith_error.
4288 * dispnew.c (deliver_window_change_signal): Rename from
4289 window_change_signal.
4290 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4291 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4292 * keyboard.c (deliver_input_available_signal): Rename from
4293 input_available_signal.
4294 (deliver_user_signal): Rename from handle_user_signal.
4295 (deliver_interrupt_signal): Rename from interrupt_signal.
4296 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4297 (deliver_child_signal): Rename from sigchld_handler.
4298 * atimer.c (handle_alarm_signal):
4299 * data.c (handle_arith_signal):
4300 * dispnew.c (handle_window_change_signal):
4301 * emacs.c (handle_fatal_signal, handle_danger_signal):
4302 * keyboard.c (handle_input_available_signal):
4303 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4304 * process.c (handle_pipe_signal, handle_child_signal):
4305 New functions, with the actual signal-handling code taken from the
4306 original respective signal handlers, sans the sporadic attempts to
4307 preserve errno, since that's now done by handle_on_main_thread.
4308 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4309 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4310 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4312 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4313 Move initialization of main_thread to sysdep.c's init_signals.
4314 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4315 our usage, and simplifies the mainline code.
4316 (record_child_status_change): New static function, as a helper
4317 for handle_child_signal, and with most of the old child handler's
4319 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4320 (handle_child_signal): Use the above.
4321 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4322 Moved here from emacs.c.
4323 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4324 code moved here from emacs.c's main function.
4325 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4326 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4327 This lets callers save and restore errno properly.
4329 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4331 Remove redundant or unused things here and there.
4332 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4333 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4334 * editfns.c (Fcompare_buffer_substrings): Likewise.
4335 * frame.h (struct terminal, struct font_driver_list):
4336 Remove redundant declarations.
4337 * window.h (Qleft, Qright): Likewise.
4339 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4341 Do not mark objects from deleted buffers, windows and frames.
4342 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4343 (mark_object): Likewise for windows and frames.
4345 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4347 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4348 buffer_defaults and buffer_local_symbols as valid objects.
4349 Return special value to denote them.
4351 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4353 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4354 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4355 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4356 (file_name_absolute_p, Fsubstitute_in_file_name):
4357 (check_executable, check_writable, Ffile_accessible_directory_p)
4358 (Fset_file_selinux_context, Fdefault_file_modes)
4359 (Finsert_file_contents, choose_write_coding_system)
4360 (Fwrite_region, build_annotations, a_write, e_write)
4362 * filelock.c (boot_time_initialized, get_boot_time)
4363 (get_boot_time_1, lock_file_1, within_one_second):
4364 * floatfns.c (in_float):
4365 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4366 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4367 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4368 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4369 * window.c (compare_window_configurations):
4370 Use bool for booleans.
4371 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4372 (Fdefault_file_modes): Now mode_t, not int, for modes.
4373 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4374 (internal_delete_file): Now returns void, not a (boolean) int,
4375 since nobody was looking at the return value.
4376 * lisp.h, window.h: Adjust to above API changes.
4378 * xdisp.c (set_message): Simplify and reindent last change.
4380 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4382 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4384 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4386 * eval.c (call_debugger): Make the function non-static so that we
4387 can call it from set_message.
4389 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4390 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4392 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4394 Give more-useful info on a fatal error (Bug#12328).
4395 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4396 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4397 of doing the work ourselves.
4398 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4399 do most of the work.
4400 (fatal_error_backtrace): New function, taken from the guts
4401 of the old fatal_error_signal, but with a new option to output
4403 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4404 info about the signal than just its number.
4405 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4406 * sysdep.c: Include <execinfo.h>
4407 (emacs_backtrace): New function, taken partly from the previous
4408 code of the 'die' function.
4409 (emacs_abort): Call fatal_error_backtrace rather than abort.
4411 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4413 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4414 eager (load-time) macro-expansion.
4415 * lisp.mk (lisp): Add macroexp.
4417 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4419 Simplify redefinition of 'abort' (Bug#12316).
4420 Do not try to redefine the 'abort' function. Instead, redo
4421 the code so that it calls 'emacs_abort' rather than 'abort'.
4422 This removes the need for the NO_ABORT configure-time macro
4423 and makes it easier to change the abort code to do a backtrace.
4424 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4425 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4426 Remove; sysdep.c's emacs_abort now takes its place.
4427 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4428 'abort' changed to use 'emacs_abort'.
4429 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4430 (abort) [!defined abort]: Rename to ...
4431 (emacs_abort): ... new name.
4432 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4433 the place of the old 'abort' in emacs.c.
4434 * w32.c, w32fns.c (abort): Do not #undef.
4435 * w32.c (emacs_abort): Rename from w32_abort.
4437 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4439 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4440 offsets[j].dv, since the y axis of the screen coordinates points
4441 down, while the y axis of the font definition coordinates points
4442 up. This fixes display of Arabic diacritics such as KASRA and
4443 KASRATAN. (Bug#11860)
4445 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4447 Be more systematic about _setjmp vs setjmp.
4448 * alloc.c (test_setjmp, mark_stack):
4449 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4450 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4451 (png_load, my_error_exit, jpeg_load):
4452 * process.c (send_process_trap, send_process):
4453 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4454 The underscored versions are up to 30x faster on some hosts.
4455 Formerly, the code used setjmp+longjmp sometimes and
4456 _setjmp+_longjmp at other times, with no particular reason to
4457 prefer setjmp+longjmp.
4459 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4461 Fix minor problem found by static checking.
4462 * buffer.c (Fdelete_all_overlays): Return nil.
4464 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4466 * buffer.c (Fdelete_all_overlays): New function.
4468 2012-09-03 Chong Yidong <cyd@gnu.org>
4470 * gtkutil.c: Add extern decl for Qxft.
4472 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4474 * emacs.c, eval.c: Use bool for boolean.
4475 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4476 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4477 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4478 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4479 (main, decode_env_path, Fdaemon_initialized):
4480 * eval.c (call_debugger, Finteractive_p, interactive_p):
4481 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4482 (maybe_call_debugger, Fbacktrace):
4483 * process.c (read_process_output, exec_sentinel):
4484 Use bool for booleans.
4485 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4486 All callers changed.
4487 * eval.c (interactive_p): Omit always-true boolean argument
4488 EXCLUDE_SUBRS_P. All callers changed.
4489 * dispextern.h, lisp.h: Reflect above API changes.
4490 * firstfile.c (dummy): Use the address of 'main', whose signature
4491 won't change, instead of the address of 'initialize', whose
4492 signature just changed from int to bool.
4493 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4494 * msdos.c (fatal_error_in_progress): ... from here.
4495 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4497 (redisplay_internal, unwind_redisplay): Simply clear
4498 REDISPLAYING_P when unwinding, instead of saving its previous,
4499 always-false value and then restoring it.
4501 Clean up some extern decls.
4502 Mostly, this hoists extern decls out of .c files and into .h files.
4503 That way, we're more likely to catch errors if the interfaces change.
4504 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4505 declare xg_mark_data.
4506 * dispextern.h (x_frame_parm_handlers):
4508 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4509 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4510 (Qultra_bold, Qoblique, Qitalic):
4511 Move extern decl here from .c file.
4512 * alloc.c (xg_mark_data) [USE_GTK]:
4514 * eval.c (Qlexical_binding):
4515 * fns.c (time) [!HAVE_UNISTD_H]:
4516 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
4517 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
4518 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
4519 * lread.c (Qinternal_interpreter_environment):
4520 * minibuf.c (Qbuffer):
4521 * process.c (QCfamily, QCfilter):
4522 * widget.c (free_frame_faces):
4523 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4524 * xfont.c (x_clear_errors):
4525 * xterm.c (x_frame_parm_handlers):
4526 Remove now-redundant extern decls.
4527 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4528 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4530 * xfaces.c: Remove unnecessary static decls.
4531 * xterm.c (updating_frame): Remove decl of nonexistent object.
4533 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4534 when building globals.h, as the objects that are not built on
4535 this host are not needed to compile C files on this host.
4537 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4539 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4541 * frame.h: Add missing prototype for x_wm_set_size_hint.
4543 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4545 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.
4546 * doc.c (read_bytecode_char, get_doc_string, reread_doc_file)
4547 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4548 (Fsubstitute_command_keys):
4549 * editfns.c (region_limit, find_field, Fconstrain_to_field)
4550 (save_excursion_save, save_excursion_restore)
4551 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
4552 (format_time_string, general_insert_function)

4591 offset adjustment values separately for each cluster. (Bug#11860)
4593 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4594 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4595 about implicit conversions from integer to pointer.

4653 window system declarations.
4655 * frame.h: Move common functions here: set_frame_menubar,
4656 x_set_window_size, x_sync, x_get_focus_frame,

4714 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4715 for GCC 4.7.1 x86-64.
4717 2012-08-30 Glenn Morris <rgm@gnu.org>
4719 * lread.c (init_lread): For out-of-tree builds, only add the
4720 source directory's site-lisp dir to the load-path if it exists,
4721 consistent with in-tree builds. (Bug#12302)
4723 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

4957 It was meant to be temporary and it often doesn't work,
4958 because when IDX has side effects the behavior of IDX==IDX
4959 is undefined. See Stefan Monnier in
4960 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

4971 as that's faster and simpler than static storage. Don't bother
4972 with the g_main_context_query overhead if g_main_context_pending
4973 says no events are pending.
4974 (gfds, gfds_size): Remove these static vars.

4976 All uses and decls removed.

5006 Use bool for booleans, instead of int.
5007 * lisp.h, process.h: Adjust prototypes to match above changes.
5008 * callint.c (Fcall_interactively): Don't assume the mark's
5009 offset fits in 'int'.
5011 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5013 * buffer.c, buffer.h: Use bool for boolean.
5014 * buffer.c (reset_buffer_local_variables)
5015 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5016 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

5018 (overlay_touches_p, overlay_strings, Foverlay_put)
5019 (report_overlay_modification, call_overlay_mod_hooks):
5020 (mmap_enlarge, mmap_set_vars):
5021 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5022 Use bool for booleans, instead of int.
5023 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5024 since the 1-or-0 return value is always ignored anyway.
5025 (mmap_initialized_p):
5026 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5027 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5029 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5031 * bidi.c: Use bool for boolean.
5032 This is a bit more readable, and makes the text segment of bidi.o
5033 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5034 Presumably it's faster too.
5035 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5037 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5038 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)

5040 (bidi_explicit_dir_char, bidi_level_of_next_char)
5041 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5042 Use bool for booleans, instead of int.
5043 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5044 (bidi_unshelve_cache): Adjust decls to match code.
5046 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5048 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5051 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5053 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5054 * atimer.h: Include <stdbool.h>.
5056 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5058 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5059 compile time tests instead of run time tests on systems that do
5061 (FRAME_MAC_P): Remove leftover from deleted code.
5062 * frame.c (syms_of_frame): Remove leftover from deleted code.
5064 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5066 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5068 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5070 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5071 Otherwise, the compiler complains about (A?B:C) where B is void
5072 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5073 (fontset_add): Return void, for FONTSET_ADD.
5075 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5077 * alloc.c: Use bool for booleans.
5078 (gc_in_progress, abort_on_gc)
5079 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5080 (dont_register_blocks) [GC_MALLOC_CHECK]:
5081 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5082 (check_string_bytes, make_specified_string, memory_full)
5083 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5084 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5085 (mark_stack, valid_pointer_p, make_pure_string)
5086 (Fgarbage_collect, survives_gc_p, gc_sweep):
5087 Use bool for booleans, instead of int.
5088 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5089 Remove unused local.
5090 * alloc.c (PURE_POINTER_P):
5091 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5092 * editfns.c (Fformat):
5093 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5095 * fns.c (sweep_weak_table):
5096 * lisp.h (suppress_checking, push_message, survives_gc_p)
5097 (make_pure_string, gc_in_progress, abort_on_gc):
5098 * lread.c (readchar, read1):
5099 * print.c (Fprin1_to_string):
5100 * xdisp.c (push_message):
5101 Use bool for booleans affected directly or indirectly by
5104 Make recently-introduced setters macros.
5105 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5106 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5107 (set_fontset_default, set_fontset_fallback): Rename from their
5108 upper-case counterparts, and make them functions rather than macros.
5109 This is more consistent with the other recently-introduced setters.
5110 These don't need to be inline, since they're local.
5112 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5114 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5115 the loop (Bug#12247).
5117 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5119 * lisp.h (vcopy): Use memcpy rather than our own loop.
5120 This fixes a performance regression introduced by the recent
5121 addition of vcopy. This means 'vcopy' will need to be modified
5122 for a copying collector, but that's OK. Also, tighten the
5123 checking in the assertion.
5125 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5127 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5128 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5129 non-base glyph for the width of the base character, according to
5130 what x_draw_composite_glyph_string_foreground expects.
5131 Generate WADJUST value according to composition_gstring_width's
5132 expectations, to produce correct width of the composed character.
5133 Reverse the sign of the DU offset produced by ScriptPlace.
5135 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5137 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5139 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5141 Avoid direct writes to contents member of struct Lisp_Vector.
5142 * lisp.h (vcopy): New function to copy data into vector.
5143 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5144 * fns.c (Ffillarray): Use ASET.
5145 * keyboard.c (timer_check_2): Use AREF and ASET.
5146 (append_tool_bar_item, Frecent_keys): Use vcopy.
5147 * lread.c (read_vector): Use ASET.
5148 * msdos.c (Frecent_doskeys): Use vcopy.
5149 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5150 (Finternal_merge_in_global_face): Use ASET and vcopy.
5151 * xfont.c (xfont_list_pattern): Likewise.
5153 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5155 * window.c (Fwindow_point): For the selected window always return
5156 the position of its buffer's point.
5157 (Fset_window_point): For the selected window always go in its
5158 buffer to the specified position.
5160 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5162 Setter macros for fontsets.
5163 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5164 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5165 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5168 2012-08-20 Glenn Morris <rgm@gnu.org>
5170 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5171 Don't assume that `ln -f' works.
5173 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5175 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5176 and later about non-assignments with no effect. See discussion at
5177 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5180 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5182 Inline setter functions for Lisp_Objects slots of struct specbinding.
5183 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5186 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5188 * window.c (select_window): Always make selected window's buffer
5191 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5193 Use AREF and ASET for docstrings of category tables.
5194 * category.h (CATEGORY_DOCSTRING): Use AREF.
5195 (SET_CATEGORY_DOCSTRING): Use ASET.
5196 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5198 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5200 Inline setter functions for hash table members.
5201 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5202 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5203 (set_hash_key_and_value, set_hash_index, set_hash_next)
5204 (set_hash_hash): New functions.
5205 * charset.c, fns.c: Adjust users.
5207 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5209 Inline getter and setter functions for per-buffer values.
5210 * buffer.h (per_buffer_default, set_per_buffer_default)
5211 (per_buffer_value, set_per_buffer_value): New functions.
5212 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5213 * buffer.c, data.c: Adjust users.
5215 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5217 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5219 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5221 Rely on <config.h> + <unistd.h> to declare 'environ',
5222 as gnulib does this if the system doesn't.
5223 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5224 Remove declaration. MS-Windows declares it on stdlib.h which is
5225 included by conf_post.h.
5226 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5227 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5228 * vm-limit.c: Include <unistd.h>, for 'environ'.
5230 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5231 (start_of_data): Remove decl; mem-limits.h provides it.
5233 * xdisp.c (handle_invisible_prop): Make it a bit faster
5234 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5236 2012-08-19 Chong Yidong <cyd@gnu.org>
5238 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5241 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5243 * .gdbinit: Use call instead of set when calling a function in the
5246 * data.c (set_internal): Don't use set_blv_found.
5247 (Fkill_local_variable): Likewise.
5249 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5251 * nsfont.m (ns_ascii_average_width): Ensure the string
5252 ascii_printable is initialized with a null-terminated character
5253 array. Otherwise, it can contain undesired extra characters.
5255 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5257 port new setting code to Sun C 5.8 2005/10/13
5258 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5259 Return void, not Lisp_Object. Otherwise, the compiler
5260 complains about (A?B:C) where B is void and C is Lisp_Object
5261 when compiling CHAR_TABLE_SET, due to the recent change to
5262 the API of sub_char_table_set_contents.
5264 2012-08-18 Chong Yidong <cyd@gnu.org>
5266 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5267 for the string case (Bug#3874).
5269 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5271 * buffer.h (BSET): Remove (Bug#12215).

5350 are compiled into code.
5351 (tset_param_alist): New setter function.
5353 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

5388 A few more naming-convention fixes for getters and setters.
5389 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,
5390 and rename from buffer_overlays_set_before.
5391 (set_buffer_overlays_after): Move here from buffer.h, and rename
5392 from buffer_overlays_set_after.
5393 * buffer.h (buffer_intervals): Rename from buffer_get_intervals.

5420 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
5421 "set_char_table_parent (char_table, parent);".
5422 The old version was confusing because it used the same name
5423 'parent' for two different things.
5425 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

6094 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6095 * w32.c (init_environment): Change the default values of many
6096 environment variables in dflt_envvars[] to NULL, to avoid pushing
6097 them into environment when they were not already defined.
6098 Remove the code that deletes site-lisp subdirectories from the default
6099 value of EMACSLOADPATH, as it is no longer needed.
6100 (check_windows_init_file): Now external, not static.
6101 Use Vload_path as is, without adding anything, as this function is now
6102 called when Vload_path is already set up.
6104 * w32.h (check_windows_init_file): Add prototype.
6106 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6113 installation tree, as appropriate.
6115 * callproc.c (init_callproc_1): Call decode_env_path instead of
6116 doing its equivalent by hand.

6134 Remove unnecessary casts involving pointers.
6135 These casts are no longer needed now that we assume C89 or later,

6149 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6150 Remove unnecessary pointer casts.
6151 * alloc.c (record_xmalloc): New function.
6152 * lisp.h (record_xmalloc): New decl.
6153 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6154 more like a function. This is because the pointer cast is not
6155 needed. All uses changed.
6156 * print.c (print_string, print_error_message): Avoid length recalc.
6158 Improve fix for macroexp crash with debugging (Bug#12118).
6159 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6160 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6161 not supposed to be invoked from the garbage collector.

6163 (gc_aset): New function, which is like ASET but can be
6164 used in the garbage collector.

6193 with addition of handling of symlinks and support for 'lstat'.
6194 If possible, get file's attributes and security information by
6195 handle, not by name. Produce S_IFLNK bit for symlinks, when
6196 called from 'lstat'.
6197 (stat, lstat): New functions, call 'stat_worker'.
6198 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6199 symlinks when the underlying filesystem supports them.
6201 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6203 Fix macroexp crash on Windows with debugging (Bug#12118).
6204 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6205 checking subscripts; problem introduced with the recent
6206 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6207 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6208 since it's used in non-static inline functions now.
6210 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6211 Don't assume buffer size fits in 'int'. Remove unused local.

6231 * composite.c (COMPOSITE_INLINE):
6232 * dispnew.c (DISPEXTERN_INLINE):
6233 * sysdep.c (SYSTIME_INLINE):
6234 Define to EXTERN_INLINE, so that the corresponding functions
6235 are compiled into code.
6236 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6237 (INLINE_HEADER_END): New macros.
6238 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6258 hard-coding the path separator.
6260 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6262 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6263 This how ASET and AREF are supposed to work, and makes
6264 it easier to think about future improvements. See
6265 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6266 * charset.h (set_charset_attr): New function.

6765 Remove; now done in lisp.h.
6766 * lisp.h (PUBLISH_TO_GDB): New macro.

6770 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6771 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6772 not be usable in #if. This simplifies things.

6781 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6782 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6783 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6784 Adjust to changes in lisp.h and emacs.c, by using
6785 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6786 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6787 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6788 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6789 instead of gdb_valbits.
6790 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6791 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6792 instead of gdb_array_mark_flag.
6793 (xboolvector): Get size from $->size, not $->header.size.
6794 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6795 (xreload, hook-run, hookpost-run): Remove.
6796 * emacs.c: Include <verify.h>.
6797 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6798 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6800 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6801 (gdb_USE_LSB_TAG): New enum constants.
6802 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

6804 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6805 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6806 as constants, so they're visible to GDB.

6808 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6809 Now enum constants, not macros, so they're visible to GDB.
6810 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6811 more convenient now. All uses changed.
6812 (VALMASK) [USE_LSB_TAG]: Also define in this case.

6825 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6827 Use typedef for EMACS_INT, EMACS_UINT.
6828 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6829 than macros. This simplifies debugging in the usual case, since
6830 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6831 and it allows expressions involving EMACS_INT casts.
6832 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6834 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6850 (init_buffer_once): Initialize indirection counters of
6851 buffer_defaults and buffer_local_symbols (for sanity and safety).
6853 2012-07-24 Eli Zaretskii <eliz@gnu.org>

6886 Swap buffer text indirection counters in Fbuffer_swap_text.
6887 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6888 This avoids crash reported by Christoph Scholtes at
6889 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6891 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6893 * nsmenu.m (Popdown_data): New struct.

6916 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6918 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6919 as it's limited by the amount of memory, not by INT_MAX.
6921 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6923 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

7074 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7076 * eval.c (Fdefvar): Don't check constants since we only set the var if
7077 it's not yet defined anyway (bug#11904).

7080 * keyboard.c (command_loop_1): Set it.
7081 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
7082 were auto-added by the command loop (bug#11774).

7663 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
7664 which are not functions. All uses rewritten to use:
7665 (make_emacs_time): New function.
7666 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
7667 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
7668 not functions. All uses rewritten to use the following, respectively:
7669 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
7670 (add_emacs_time, sub_emacs_time): New functions.
7671 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

7697 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7698 * nsterm.m (ns_term_init):
7699 Avoid the need for strncpy, by using build_string or
7700 make_unibyte_string directly. Use dtoastr, not snprintf.
7701 * process.c (Fmake_network_process): Diagnose service names that
7702 are too long, rather than silently truncating them or creating
7703 non-null-terminated names.
7704 (Fnetwork_interface_info): Likewise, for interface names.
7705 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7706 Prefer sprintf to strncat.
7707 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
7708 Prefer vsnprintf to vsprintf + strncpy.

7713 Clarify fallback case.
7715 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

7719 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7720 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

7733 Optimize pure C strings initialization.
7734 * lisp.h (make_pure_string): Fix prototype.
7735 (build_pure_c_string): New function, defined as static inline. This
7736 provides a better opportunity to optimize away calls to strlen when
7737 the function is called with compile-time constant argument.
7738 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7739 argument, adjust users accordingly. Use build_pure_c_string where
7741 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7742 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7743 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7745 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7747 Avoid calls to strlen in miscellaneous functions.
7748 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7749 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7750 * lread.c (openp): Likewise.

7754 Avoid calls to strlen in path processing functions.
7755 * fileio.c (file_name_as_directory): Add comment. Change to add
7756 srclen argument and return the length of result. Adjust users

7760 Adjust users accordingly.
7761 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7763 2012-07-10 Glenn Morris <rgm@gnu.org>
7765 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

7770 * s/gnu.h (DATA_START): Move definitions to configure.
7772 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7773 We include usg5-4-common.h, which defines them both.
7775 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7776 O_RDONLY already includes it).
7778 Stop ns builds setting the EMACSLOADPATH environment variable.
7779 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7780 Now it does not set EMACSLOADPATH, just returns the load-path string.
7781 * nsterm.h: Update accordingly.
7782 * lread.c [HAVE_NS]: Include nsterm.h.
7783 (init_lread) [HAVE_NS]: Use ns_load_path.

7786 2012-07-09 Glenn Morris <rgm@gnu.org>
7788 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7789 since the included bsd-common.h does so.
7791 Stop ns builds setting the EMACSPATH environment variable.
7792 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7793 (ns_init_paths): Do not set EMACSPATH.
7794 * nsterm.h (ns_exec_path): Add it.
7795 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7798 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7800 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7802 * process.c (wait_reading_process_output): 'waitchannels' was unset
7803 when read_kbd || !NILP (wait_for_cell); fix this.
7805 Add GCC-style 'const' attribute to functions that can use it.
7806 * character.h (char_resolve_modifier_mask):
7807 * keyboard.h (make_ctrl_char):
7808 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7815 Declare the dummy function with ATTRIBUTE_CONST.
7816 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7817 Add decls with ATTRIBUTE_CONST.
7819 Minor improvements to make_formatted_string.
7820 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7821 where int is good enough, as vsprintf returns an int.
7822 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7824 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7826 Use make_formatted_string to avoid double length calculation.
7827 * lisp.h (make_formatted_string): New prototype.
7828 * alloc.c (make_formatted_string): New function.
7829 * buffer.c (Fgenerate_new_buffer_name): Use it.

7851 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7853 Move marker debugging code under MARKER_DEBUG.
7854 * marker.c (MARKER_DEBUG): Move marker debugging code under
7855 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7856 for bootstrap with --enable-checking (~3x slowdown reported
7857 by Juanma Barranquero <lekktu@gmail.com>).
7858 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7860 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7862 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7863 See <http://bugs.gnu.org/11825#29>.
7865 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7867 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7868 has no font, use the frame's font. (Bug#11813)
7869 (display_line): Add commentary about displaying truncation glyphs
7871 (produce_special_glyphs): Move here from term.c.
7873 * term.c (produce_special_glyphs): Move to xdisp.c.
7875 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7878 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7880 * xdisp.c (display_line): Avoid warning about implicit declaration
7883 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7885 * lisp.h: Remove empty conditional.
7887 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7889 * lread.c (load_path_check): Now static.
7891 Fix some minor --with-ns problems found by static checking.
7892 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7893 (x_set_font) [!HAVE_X_WINDOWS]:
7894 * image.c (xpm_load_image) [HAVE_NS]:
7895 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7896 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7897 Remove unused local.
7898 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7899 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7900 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7901 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7902 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7903 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7904 Fix pointer signedness problem.
7905 * xfaces.c (FRAME_X_FONT_TABLE):
7906 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7908 2012-07-07 Glenn Morris <rgm@gnu.org>
7910 * lread.c (load_path_check): New function, split from init_lread.
7911 (init_lread): Reorganize. Motivation:
7912 If EMACSLOADPATH is set, check/warn about that rather than the
7913 defaults, which we are not going to use. Hence we can remove
7914 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7915 Don't warn if site-lisp directories are missing.
7916 If not installed, start from a blank load-path, since
7917 PATH_LOADSEARCH refers to the eventual installation directories.
7919 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7921 Support truncation and continuation glyphs on GUI frames, when
7922 fringes are disabled. (Bug#11832)
7923 * xdisp.c (init_iterator): Get dimensions of truncation and
7924 continuation glyphs even if on GUI frames.
7925 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7926 or both, are absent.
7927 (start_display, move_it_in_display_line_to): Handle the case of a
7928 GUI frame without a fringe to display continuation or truncation
7930 (insert_left_trunc_glyphs): Support GUI frames: make sure
7931 truncation glyphs overwrite enough glyphs from the current line to
7932 have sufficient space in pixels.
7933 (display_line): Support truncation and continuation glyphs on GUI
7934 frames. If some spare pixels are left on the line after inserting
7935 the truncation glyphs, fill that space with a stretch glyph of a
7936 suitably computed width.
7938 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7939 produce_glyphs, to support GUI sessions.
7941 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7943 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7945 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7947 Do not require float-time's arg to fit in time_t (Bug#11825).
7948 This works better on hosts where time_t is unsigned, and where
7949 float-time is applied to the (negative) difference between two times.
7950 * editfns.c (decode_time_components): Last arg is now double *,
7951 not int *, and means to store all the result as a double, without
7952 worrying about whether the seconds part fits in time_t.
7953 All callers changed.
7954 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7955 All callers changed.
7956 (Ffloat_time): Do not fail merely because the specified time falls
7957 outside of time_t range.
7959 2012-07-07 Glenn Morris <rgm@gnu.org>
7961 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
7962 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
7963 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
7965 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
7967 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7968 Update dependencies.
7970 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7972 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7974 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

7976 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7977 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7978 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7979 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7981 * xfont.c (compare_font_names): Redo to omit the need for casts.
7983 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7985 * xfns.c (Fx_change_window_property): Doc fix.
7986 * w32fns.c (Fx_change_window_property): Doc fix.
7988 * w32fns.c (Fx_window_property): Accept the same arguments as the
7989 X Windows version. Doc fix.
7990 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7992 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7993 Eli Zaretskii <eliz@gnu.org>
7995 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7996 Windows-specific code from nt/config.nt moved here.
7997 Obsolete settings removed.
7999 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8001 * process.c: Avoid unnecessary calls to gettime.
8002 (wait_reading_process_output): Don't get the time of day
8003 when gobbling data immediately and not waiting, as there's no need
8004 for it in that case. This removes a FIXME.
8006 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8008 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8009 is defined (Bug#11768).
8011 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8013 Fix marker debugging code.
8014 * marker.c (byte_char_debug_check): Do not perform the check
8015 if buffer is not multibyte.
8016 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8017 Call byte_char_debug_check with correct arguments.
8019 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8021 Compile marker debugging code only if ENABLE_CHECKING is defined.
8022 * marker.c (byte_char_debug_check, count_markers):
8023 Use only if ENABLE_CHECKING is defined.
8024 (byte_debug_flag): Remove.
8025 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8026 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8028 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8030 Avoid code repetition in marker-related functions.
8031 * marker.c (attach_marker): New function.
8032 (Fset_marker, set_marker_restricted, set_marker_both)
8033 (set_marker_restricted_both): Use it.
8034 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8035 Consistently rename charno to charpos.
8036 (marker_position): Add eassert.
8037 (marker_byte_position): Convert to eassert.
8039 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8041 Simplify list operations in unchain_overlay and unchain_marker.
8042 * buffer.c (unchain_overlay): Simplify. Add comment.
8043 * marker.c (unchain_marker): Simplify. Fix comments.
8045 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8047 Introduce fast path for the widely used marker operation.
8048 * alloc.c (build_marker): New function.
8049 * lisp.h (build_marker): New prototype.
8050 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
8051 * composite.c (autocmp_chars): Likewise.
8052 * editfns.c (buildmark): Remove.
8053 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8054 (save_restriction_save): Use build_marker.
8055 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8056 * window.c (save_window_save): Likewise.
8058 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8060 Do not use Fdelete_overlay in delete_all_overlays
8061 to avoid redundant calls to unchain_overlay.
8062 * buffer.c (drop_overlay): New function.
8063 (delete_all_overlays, Fdelete_overlay): Use it.
8064 * minibuf.c (get_minibuffer): Fix comment.
8066 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8068 Port to OpenBSD 5.1 amd64.
8069 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8070 This is needed for OpenBSD, and should be harmless on all BSD systems.
8071 Also, include <sys/sysctl.h>, as it should be available on all
8072 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8073 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8074 use p_pid member, not kp_proc.pid.
8076 2012-07-06 Glenn Morris <rgm@gnu.org>
8078 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8080 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8082 More xmalloc and related cleanup.
8083 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8084 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
8085 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
8086 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
8087 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
8088 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
8089 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
8090 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8091 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8093 Omit needless casts involving void * pointers and allocation.
8094 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8095 as the former is more robust if P's type is changed.
8096 Prefer xzalloc to xmalloc + memset 0.
8097 Simplify malloc-or-realloc to realloc.
8098 Don't worry about xmalloc returning a null pointer.
8099 Prefer xstrdup to xmalloc + strcpy.
8100 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8102 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8103 alloca of a constant.
8105 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8107 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8108 hscroll is larger than the line width. Fixes long and futile
8109 looping inside extend_face_to_end_of_line (on a TTY) producing
8110 glyphs that are not needed and thrown away.
8112 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8114 * marker.c (set_marker_restricted_both): Simplify by using

8124 not defined (Bug#11768).
8125 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
8126 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
8127 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
8128 followed by gtk_box_set_homogeneous (Bug#11768).
8129 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8130 (update_theme_scrollbar_width, xg_create_scroll_bar):
8131 Use gtk_scrollbar_new (Bug#11768).
8132 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

8140 * xdisp.c (window_hscroll_limited): New function.
8141 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8142 coordinates when window's hscroll is set to insanely large
8145 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8147 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8209 Problem reported by Troels Nielsen in
8210 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8212 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8214 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8215 This should be fixed in a better way; see Eli Zaretskii in
8216 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8217 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8219 * fileio.c (time_error_value): Rename from special_mtime.
8220 The old name's problems were noted by Eli Zaretskii in
8221 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8223 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8224 This variable's comment says Emacs needs at least one GDB-visible
8225 symbol of type enum pvec_type, to work around GDB problems.
8226 The symbol's value doesn't matter.
8228 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8229 that causes compilation to fail on pre-C99 compilers.
8231 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8233 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8234 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8236 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8238 * buffer.c (init_buffer_once): Fix initialization of
8239 headers for buffer_defaults and buffer_local_symbols.
8240 Reported by Juanma Barranquero <lekktu@gmail.com>.
8242 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8244 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8245 * lisp.h (enum pvec_type): Use fewer bits.
8246 (PSEUDOVECTOR_SIZE_BITS): New constant.
8247 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8248 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8249 change in pvec_type.
8250 (PSEUDOVECTOR_TYPEP): New macro.
8251 (TYPED_PSEUDOVECTORP): Use it.
8252 * fns.c (internal_equal): Adapt code to extract pvectype.

8254 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8255 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8256 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8257 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8258 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8259 abusing vector->header.next.nbytes.
8260 (live_vector_p): Use PVEC_TYPE.
8261 (mark_object): Adapt code to extract pvectype. Use switch.
8263 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8265 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8266 Tighten new eassert a bit.
8268 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8270 Fix compilation with --enable-gcc-warnings and -O1
8272 * doprnt.c (doprnt): Change type of tem to int, initialize
8273 to avoid compiler warning. Add eassert.
8274 * search.c (simple_search): Initialize match_byte to avoid
8275 compiler warning. Add eassert.
8277 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8279 Avoid weird behavior with large horizontal scrolls.
8280 Without this change, for example, large hscroll values would
8281 mess up Emacs's display on Fedora 15 x86, presumably due to
8282 overflows in int calculations in the display code.
8283 Also, if buffers had long lines, Emacs would freeze.
8284 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8285 (set_window_hscroll): New function, containing the old guts of
8286 Fset_window_hscroll. Return the clipped value.
8287 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8288 This avoids the need to check against PTRDIFF_MAX.
8290 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8292 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8294 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8296 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8298 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8299 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8300 since GCC 4.4.6 issues a bogus warning for them.
8302 Fix bugs in file timestamp newness comparisons.
8303 * fileio.c (Ffile_newer_than_file_p):
8304 * lread.c (Fload): Use full timestamp resolution of files,
8305 not just the 1-second resolution, so that files that are only
8306 slightly newer still count as newer.
8307 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8308 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8310 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8312 * fileio.c: Improve handling of file time marker. (Bug#11852)
8313 (special_mtime): New function.
8314 (Finsert_file_contents, Fverify_visited_file_modtime):
8315 Use it to set special mtime values consistently.
8317 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8319 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8320 marker for non-existing file. (Bug#11852)
8322 2012-07-03 Glenn Morris <rgm@gnu.org>
8324 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8325 and did not make it into globals.h).
8327 2012-07-03 Tom Tromey <tromey@redhat.com>
8329 * window.c (Fset_window_margins, Fset_window_fringes)
8330 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8331 * textprop.c (Fprevious_property_change): No longer static.
8332 * syntax.c (Fsyntax_table_p): No longer static.

8354 * intervals.h: Remove EXFUNs.
8355 * fontset.h: Remove EXFUN.

8360 * w32term.h: Remove EXFUNs.
8361 * window.h: Remove EXFUNs.

8363 * xterm.h: Remove EXFUN.
8365 2012-07-03 Glenn Morris <rgm@gnu.org>
8367 * lisp.h (Frandom): Make it visible to C.
8368 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8369 buffer for invisible buffers. (Bug#1229)

8373 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8374 values which aren't power of 2.
8375 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8376 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8379 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8381 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8383 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8385 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8387 * alloc.c (allocate_vector_block): Remove redundant
8388 calls to mallopt if DOUG_LEA_MALLOC is defined.
8389 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8390 avoid calls to mallopt if zero_vector is returned.
8392 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8394 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8395 is enabled, avoid dereferencing NULL current_sblock if
8398 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8400 Cleanup basic buffer management.
8401 * buffer.h (struct buffer): Change layout to use generic vector
8402 marking code. Fix some comments. Change type of 'clip_changed'
8403 to bitfield. Remove unused #ifndef old.
8404 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8405 (GET_OVERLAYS_AT): Fix indentation.
8406 (for_each_per_buffer_object_at): New macro.

8410 * alloc.c (allocate_buffer): Adjust to match new layout of
8411 struct buffer. Fix comment.
8412 (mark_overlay): New function.

8414 Lisp area of struct buffer.
8415 (mark_object): Use it. Adjust marking of misc objects
8416 and related comments.
8418 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8420 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8421 wrapper that is not needed because the wrapped code is a no-op (zero
8422 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8423 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8425 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8427 * alloc.c (mark_buffer): Simplify. Remove prototype.
8428 (mark_object): Add comment. Reorganize marking of vector-like
8429 objects. Use CHECK_LIVE for all vector-like objects except buffers
8430 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8431 Avoid redundant calls to mark_vectorlike for bool vectors.
8433 2012-06-30 Glenn Morris <rgm@gnu.org>
8435 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8437 * epaths.in (PATH_SITELOADSEARCH): New.
8438 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8439 This is rather than relying on --enable-locallisppath elements
8440 having "site-lisp" in their names. (Bug#10208#25, 11658)
8442 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8444 * w32proc.c (sys_select): Accept and ignore one more argument.
8446 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8448 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8449 (pselect) [!MS_DOS]: Redirect to sys_select.
8451 * sysdep.c: Don't include dos.h and dosfns.h.
8453 * process.c (sys_select):
8454 * msdos.c (sys_select): Accept one more argument and ignore it.
8456 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8457 adapt data types and code to that.
8460 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8461 which clashes with the gnulib function of the same name.
8463 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8465 * font.c (font_style_to_value, font_style_symbolic)
8466 (font_prop_validate_style): Add type checks for values in
8469 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8471 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8474 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8476 * xdisp.c (try_window_id): Undo last change.
8478 * w32.c (getwd): Adjust commentary about startup_dir.
8479 (init_environment): Always call sys_access, even in non-MSVC
8480 builds. Don't chdir to the directory of the Emacs executable.
8481 This undoes code from 1997 which was justified by the need to
8482 "avoid conflicts when removing and renaming directories". But its
8483 downside was that every relative file name was being interpreted
8484 relative to the directory of the Emacs executable, which can never
8485 be TRT. In particular, it broke sys_access when called with
8486 relative file names.
8487 (sys_access): Map GetLastError to errno.
8489 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8491 * window.h (struct window): Change type of 'fringes_outside_margins'

8493 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
8495 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8498 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8500 * gnutls.c (emacs_gnutls_handshake):
8501 Add QUIT to make the loop interruptible.
8503 2012-06-29 Glenn Morris <rgm@gnu.org>
8505 * charset.c (init_charset): Make lack of etc/charsets fatal.
8507 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8509 * editfns.c (region_limit): Fix type mismatch.
8511 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8513 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8514 undefined. Convert from xassert to eassert.
8515 * nsmenu.m: Convert from xassert to eassert.
8516 * nsterm.m: Likewise.
8518 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8520 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8522 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8524 Avoid integer overflow on scroll-left and scroll-right.
8525 * window.c (HSCROLL_MAX): New macro.
8526 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8527 overflow when requested scroll falls outside ptrdiff_t range.
8529 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8531 * window.h (struct window): Change type of 'hscroll',
8532 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8533 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8534 Adjust users accordingly.
8535 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8536 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8537 from EMACS_INT to ptrdiff_t.
8538 (make_window): Omit redundant initialization.
8540 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8542 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8544 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8546 * window.h (struct window): Change type of 'use_time' and
8547 'sequence_number' from Lisp_Object to int.
8548 * frame.c (make_frame): Adjust users accordingly.
8549 * print.c (print_object): Likewise.

8551 (make_window): Likewise.
8553 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8555 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
8556 enabled with --enable-checking=[all,glyphs] configure option.
8557 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8558 adjust comments accordingly.
8559 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
8560 undefined, adjust comments accordingly.

8679 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8681 Use sprintf return value instead of invoking strlen on result.
8682 In the old days this wasn't portable, since some sprintf
8683 implementations returned char *. But they died out years ago and
8684 Emacs already assumes sprintf returns int.
8685 Similarly for float_to_string.
8686 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8694 Use sprintf or float_to_string result to avoid need to call strlen.
8695 * data.c (Fnumber_to_string):
8696 Use make_unibyte_string, since the string must be ASCII.
8697 * lisp.h, print.c (float_to_string): Now returns int length.
8698 * term.c (produce_glyphless_glyph):
8699 Use sprintf result rather than recomputing it.
8701 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8702 * Makefile.in (ALL_CFLAGS):
8703 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8732 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8734 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
8735 `const char *' to `char *' to avoid compiler warning.
8737 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8739 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8740 instead of truncating it to 63 (admittedly a generous limit).

8800 * keyboard.c (kbd_buffer_get_event):
8801 * process.c (Faccept_process_output):
8802 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8803 This improves on the previous patch, which introduced a bug
8804 when time_t is unsigned and as wide as intmax_t.
8805 See <http://bugs.gnu.org/9000#51>.
8807 2012-06-23 Eli Zaretskii <eliz@gnu.org>

8824 Privately reported by Herbert J. Skuhra.
8825 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

8836 language ID in the event parameters.
8838 * w32term.c (w32_read_socket): Put the new keyboard codepage into
8839 event.code, not the obscure "character set ID".

8870 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8872 Support higher-resolution time stamps (Bug#9000).
8873 The time stamps are only nanosecond-resolution at the C level,
8874 since that's the best that any real-world system supports now.
8875 But they are picosecond-resolution at the Lisp level, as that's
8876 easy, and leaves room for future OS improvements.
8878 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8881 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8882 Don't get current time unless it's needed.
8884 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8885 now provides it if it's absent.
8886 (start_atimer): Port to higher-res time stamps.
8887 Check for time stamp overflow. Don't get current time more
8888 often than is needed.
8890 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8891 Include systime.h, not time.h.
8892 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8894 * dired.c: Include stat-time.h.
8895 (Ffile-attributes): File times now have higher resolution.

8898 (struct image): Timestamp now has higher resolution.
8900 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8901 has at least microseconds now. All uses removed.
8902 (update_frame, update_single_window, update_window, update_frame_1)
8903 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8904 (duration_to_sec_usec): Remove; no longer needed.
8906 * editfns.c (time_overflow): Now extern.
8907 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8908 (float-time, Fformat_time_string, Fcurrent_time_string)

8912 (decode_time_components, lisp_seconds_argument): New functions.
8913 (make_time): Now static.
8914 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8915 Report an error if the time is invalid, rather than having the caller
8918 * fileio.c: Include <stat-time.h>
8919 (Fcopy_file): Copy higher-resolution time stamps.
8920 Prefer to set the time stamp via a file descriptor if that works.

8922 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8923 (Fvisited_file_modtime, Fset_visited_file_modtime):
8924 Support higher-resolution time stamps.
8926 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8928 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8930 * image.c (prepare_image_for_display, clear_image_cache)
8931 (lookup_image): Port to higer-resolution time stamps.
8933 * keyboard.c (start_polling, bind_polling_period):
8934 Check for time stamp overflow.
8935 (read_char, kbd_buffer_get_event, timer_start_idle)
8936 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8937 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8938 Port to higher-resolution time stamps. Do not assume time_t is signed.
8939 (decode_timer): New function. Timers are now vectors of length 9,
8940 not 8, to accommodate the picosecond component.
8941 (timer_check_2): Use it.
8943 * nsterm.m (select_timeout, timeval_subtract): Remove.
8944 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8945 as they're a bit more accurate and handle overflow better.
8946 (ns_select): Change prototype to be compatible with pselect.
8947 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8948 * nsterm.h (ns_select): Adjust prototype.
8950 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8951 us-resolution time stamps.
8952 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8954 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8956 * lisp.h (time_overflow): New decl.
8957 (wait_reading_process_output): First arg is now intmax_t, not int,
8958 to accommodate larger waits.
8960 * process.h (struct Lisp_Process.read_output_delay):
8961 Now counts nanoseconds, not microseconds.
8962 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8964 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8965 (wait_reading_process_output):
8966 Port to ns-resolution time stamps.
8967 (Faccept_process_output, wait_reading_process_output):
8968 Check for time stamp overflow. Do not assume time_t is signed.
8969 (select_wrapper): Remove; we now use pselect.
8970 (Fprocess_attributes): Now generates ns-resolution time stamps.
8972 * sysdep.c: Include utimens.h. Don't include utime.h
8973 or worry about struct utimbuf; gnulib does that for us now.
8974 (gettimeofday): Remove; gnulib provides a substitute.
8975 (make_timeval): New function.
8976 (set_file_times): Now sets ns-resolution time stamps.
8977 New arg FD; all uses changed.
8978 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8979 (system_process_attributes):
8980 Now returns ns-resolution time stamp. All uses changed.
8981 Check for time stamp overflow.
8983 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8984 provides a substitute now.
8986 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8987 since it guarantees struct timespec.
8988 (EMACS_TIME): Now struct timespec, so that we can support
8989 ns-resolution time stamps.
8990 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8991 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8992 (EMACS_USECS): Remove.
8993 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8994 so multiply the arg by 1000 before storing it.
8995 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8997 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8998 Port to ns-resolution time stamps.
8999 (EMACS_TIME_NEG_P): Remove; replaced by....
9000 (EMACS_TIME_SIGN): New macro.
9001 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9002 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

9004 (make_timeval, make_lisp_time, decode_time_components): New decls.
9005 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9006 that it mishandled time_t overflow. You can't compare by subtracting!
9007 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9008 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9010 * term.c: Include <sys/time.h>.
9011 (timeval_to_Time): New function, for proper overflow wraparound.
9012 (term_mouse_position, term_mouse_click): Use it.
9014 * undo.c (record_first_change): Support higher-resolution time stamps
9016 (Fprimitive_undo): Use them when restoring time stamps.
9018 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9019 (w32_get_internal_run_time):
9020 Port to higher-resolution Emacs time stamps.
9021 (ltime): Now accepts single 64-bit integer, as that's more convenient
9024 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9026 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9027 for compatibility with pselect. Support ns-resolution time stamps.
9029 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9031 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9032 Check for time stamp overflow, and support ns-resolution time stamps.
9034 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9035 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9036 (timeval_subtract): Remove; no longer needed.
9037 (XTflash, XTring_bell, x_wait_for_event):
9038 Port to ns-resolution time stamps. Don't assume time_t is signed.
9040 2012-06-22 Chong Yidong <cyd@gnu.org>
9042 * xdisp.c (x_consider_frame_title): Revert last change.
9044 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9046 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9047 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9048 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9049 staticidx goes up to 1597 out of 1600 = 0x640.)
9051 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9053 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9054 Otherwise, the umask might be mistakenly 0 while handling input signals.
9056 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9058 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9064 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9065 access to `contents' member of Lisp_Vector objects with AREF and ASET

9321 code works fine either way, and efficiency is not a concern here,
9322 as the union type is for debugging, not for production.
9323 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9324 Use an inline function on all platforms when using the union type,
9325 since this is simpler and 'static inline' can be used portably

9470 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9471 would mishandle a string argument "Xc" if X was a multibyte
9472 character of length 2: it would truncate after X's first byte
9473 rather than including all of X.

9547 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9548 fields from Lisp_Object to bitfield. Adjust users accordingly.
9550 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9552 Pacify gcc -Wdouble-precision when using Xaw.
9553 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9554 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9555 Use 'float' consistently, rather than 'float' in most places
9556 and 'double' in a couple of places.
9558 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9560 * xdisp.c (handle_stop): Detect whether we have overlay strings
9561 loaded by testing it->current.overlay_string_index to be
9562 non-negative, instead of checking whether n_overlay_strings is
9563 positive. (Bug#11587)
9565 2012-05-31 Chong Yidong <cyd@gnu.org>
9567 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9569 * doc.c (Fsubstitute_command_keys): Doc fix.
9571 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9573 * search.c (search_buffer): Remove calls to
9574 r_alloc_inhibit_buffer_relocation, as it is now called by
9575 maybe_unify_char, which was the cause of relocation of buffer text
9578 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9580 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9581 for the duration of call to load_charset, to avoid problems with
9582 callers of maybe_unify_char that access buffer text through C
9585 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9586 decrement the inhibition flag, instead of just setting or
9589 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9591 Remove obsolete '#define static' cruft.
9592 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9593 This #undef was "temporary" in 2000; it is no longer needed
9594 now that '#define static' has gone away.
9595 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9596 (gray_bitmap_bits): Remove; no longer needed.
9597 All uses replaced with definiens.
9598 * xterm.c: Include "bitmaps/gray.xbm".
9600 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9602 Clean up __executable_start, monstartup when --enable-profiling.
9603 The following changes affect the code only when profiling.
9604 * dispnew.c (__executable_start): Rename from safe_bcopy.
9605 Define only on platforms that need it.
9606 * emacs.c: Include <sys/gmon.h> when profiling.
9607 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9608 (__executable_start): Remove decl, since lisp.h does it now.
9609 (safe_bcopy): Remove decl; no longer has that name.
9610 (main): Coalesce #if into single bit of code, for simplicity.
9611 Cast pointers to uintptr_t, since standard libraries want integers
9613 * lisp.h (__executable_start): New decl.
9615 2012-05-31 Glenn Morris <rgm@gnu.org>
9617 * image.c (Fimagemagick_types): Doc fix.
9619 2012-05-30 Jim Meyering <meyering@redhat.com>
9621 * callproc.c (Fcall_process_region): Include directory component
9622 in mkstemp error message (Bug#11586).
9624 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9626 * alloc.c, lisp.h (make_pure_vector): Now static.
9628 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

9633 * data.c (Fdefalias): Purify definition, except for keymaps.
9634 (Qdefun): Move from eval.c.
9635 * lisp.h (Qdefun): Remove.
9636 * lread.c (read1): Tiny simplification.
9638 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9640 Do not create empty overlays with the evaporate property (Bug#9642).
9641 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9642 Bug#9642, but explicitly check that the buffer the overlay would
9643 be moved to is live and rearrange lines to make sure that errors
9644 will not put the overlay in an inconsistent state.
9645 (Fdelete_overlay): Cosmetics.
9647 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9649 * w32term.c (my_bring_window_to_top): New function.
9650 (x_raise_frame): Use handle returned by DeferWindowPos, which
9651 could be different from the original one.
9652 Call my_bring_window_to_top instead of my_set_foreground_window.
9655 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9656 by calling BringWindowToTop.
9658 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9659 (WM_EMACS_END): Increase by one.
9661 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9663 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9664 This avoids undefined behavior that might cause the eassert
9665 to not catch an out-of-range value.
9667 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9669 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9670 Update dependencies.
9672 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9674 * bidi.c (bidi_mirror_char): Fix last change.
9676 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9678 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9679 when referring to sectname field in printf format.
9681 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9683 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9684 Only r_alloc_inhibit_buffer_relocation needed to be added;
9685 the others were already declared.
9687 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9688 before checking whether it's out of range. Put the check inside
9690 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9692 2012-05-27 Ken Brown <kbrown@cornell.edu>
9694 * callproc.c (Fcall_process): Restore a line that was accidentally
9695 commented out in the 2011-02-13 change (bug#11547).
9697 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9699 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9700 defined on ralloc.c.
9702 * buffer.c [REL_ALLOC]: Remove prototypes of
9703 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9704 they are now on lisp.h.
9706 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9708 * search.c (search_buffer): Use it to inhibit relocation of buffer
9709 text while re_search_2 is doing its job, because re_search_2 is
9710 passed C pointers to buffer text. (Bug#11519)
9712 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9715 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9716 state after an additional call to move_it_in_display_line_to, keep
9717 the values of it->max_ascent and it->max_descent found for the
9719 (pos_visible_p): Revert the comparison against bottom_y to what it
9720 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9723 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9725 Fix coding-related core dumps with gcc -ftrapv.
9726 The code was computing A - B, where A and B are pointers, and B is
9727 random garbage. This can lead to core dumps on platforms that
9728 have special pointer registers, and it also leads to core dumps on
9729 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9730 A - B only when B is initialized properly.
9731 * coding.c (coding_set_source, coding_set_destination): Return void.
9732 (coding_change_source, coding_change_destinations): New functions,
9733 with the old behaviors of coding_set_source and coding_set_destination.
9734 All callers that need an offset changed to use these new functions.
9736 2012-05-26 Glenn Morris <rgm@gnu.org>
9738 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9740 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9742 Extend mouse support on W32 text-mode console.
9743 * xdisp.c (draw_row_with_mouse_face):
9744 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9746 * w32console.c: Include window.h.
9747 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9749 (initialize_w32_display): Initialize mouse-highlight data.
9751 * w32inevt.c: Include termchar.h and window.h.
9752 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9753 moves, call note_mouse_highlight. If help_echo changed, call
9754 gen_help_event to produce help-echo message in the echo area.
9755 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9758 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9760 * lread.c (read1): Simplify slightly to avoid an overflow warning
9761 with GCC 4.7.0 on x86-64.
9763 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9765 * bidi.c (bidi_mirror_char): Revert last change: an int is
9766 definitely wide enough here.
9768 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9770 Fix integer width and related bugs (Bug#9874).
9771 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9772 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
9773 (string_bytes, check_sblock, allocate_string_data):
9774 (compact_small_strings, Fmake_bool_vector, make_string)
9775 (make_unibyte_string, make_multibyte_string)
9776 (make_string_from_bytes, make_specified_string)
9777 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
9778 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9780 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9781 (allocate_pseudovector):
9782 Use int, not EMACS_INT, where int is wide enough.
9783 (inhibit_garbage_collection, Fgarbage_collect):
9784 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9785 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9786 int might not be wide enough.
9787 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9788 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
9789 (bidi_at_paragraph_end, bidi_find_paragraph_start)
9790 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9791 (bidi_level_of_next_char, bidi_move_to_visually_next):
9792 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9793 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9794 (Fkill_buffer, Fset_buffer_major_mode)
9795 (advance_to_char_boundary, Fbuffer_swap_text)
9796 (Fset_buffer_multibyte, overlays_at, overlays_in)
9797 (overlay_touches_p, struct sortvec, record_overlay_string)
9798 (overlay_strings, recenter_overlay_lists)
9799 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9800 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9801 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9802 (Foverlay_recenter, last_overlay_modification_hooks_used)
9803 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9804 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9805 (validate_region): Omit unnecessary test for b <= e,
9806 since that's guaranteed by the previous test.
9807 (adjust_overlays_for_delete): Avoid pos + length overflow.
9808 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9809 (report_overlay_modification):
9810 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9811 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9812 Omit pointer cast, which isn't needed anyway, and doesn't work
9813 after the EMACS_INT -> ptrdiff_t change.
9814 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9815 * buffer.h: Adjust decls to match defn changes elsewhere.
9816 (struct buffer_text, struct buffer):

9818 Use EMACS_INT, not int, where int might not be wide enough.
9819 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9820 not int, to avoid needless 32-bit limit on 64-bit hosts.
9821 (exec_byte_code): Use tighter memory-full test, one that checks
9822 for alloca overflow. Don't compute the address of the object just
9823 before an array, as that's not portable. Use EMACS_INT, not
9824 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9825 * callint.c (Fcall_interactively):
9826 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9827 * callproc.c (call_process_kill, Fcall_process):
9828 Don't assume pid_t fits into an Emacs fixnum.
9829 (call_process_cleanup, Fcall_process, child_setup):
9830 Don't assume pid_t fits into int.
9831 (call_process_cleanup, Fcall_process, delete_temp_file)
9832 (Fcall_process_region):
9833 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9834 (Fcall_process): Simplify handling of volatile integers.
9835 Use int, not EMACS_INT, where int will do.
9836 * casefiddle.c (casify_object, casify_region, operate_on_word)
9837 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9838 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9839 (casify_object): Avoid integer overflow when overallocating buffer.
9840 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9841 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9842 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9843 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9844 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9845 integers are now checked earlier. All uses replaced with XINT.
9847 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9848 For CCL_MapSingle, check that content and value are in int range.
9849 (ccl_driver, Fregister_code_conversion_map):
9850 Check that Vcode_version_map_vector is a vector.
9851 (resolve_symbol_ccl_program): Check that vector header is in range.
9852 Always copy the vector, so that we can check its contents reliably
9853 now rather than having to recheck each instruction as it's being
9854 executed. Check that vector words fit in 'int'.
9855 (ccl_get_compiled_code, Fregister_ccl_program)
9856 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9857 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9858 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9859 contents are in range.
9860 (Fccl_execute_on_string): Check that status is in range.
9861 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9862 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9863 Accept and return EMACS_INT, not int, because callers can pass values
9865 (c_string_width, strwidth, lisp_string_width, chars_in_text)
9866 (multibyte_chars_in_text, parse_str_as_multibyte)
9867 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
9868 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9869 (string_escape_byte8, Fget_byte):
9870 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9871 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9872 avoid mishandling large integers.
9873 * character.h: Adjust decls to match defn changes elsewhere.
9874 * charset.c (load_charset_map_from_file, find_charsets_in_text)
9875 (Ffind_charset_region):
9876 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9877 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
9878 (load_charset_map_from_vector, Fdefine_charset_internal):
9879 Don't assume fixnum fits in int.
9880 (load_charset_map_from_vector, Fmap_charset_chars):
9881 Remove now-unnecessary CHECK_NATNUMs.
9882 (Fdefine_charset_internal): Check ranges here, more carefully.
9883 Don't rely on undefined behavior with signed left shift overflow.
9884 Don't assume unsigned int fits into fixnum, or that fixnum fits
9885 into unsigned int. Don't require max_code to be a valid fixnum;
9886 that's not true for gb10830 4-byte on a 32-bit host. Allow
9887 invalid_code to be a cons, for the same reason. Require code_offset
9888 to be a character. Avoid int overflow if max_char is close
9890 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9891 this is intended anyway and avoids some undefined behavior.
9892 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9893 INDEX_TO_CODE_POINT, as that's what it expects.
9894 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9895 * charset.h (DECODE_CHAR): Return int, not unsigned;
9896 this is what was intended anyway, and it avoids undefined behavior.
9897 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9898 integer-overflow issues.
9899 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9900 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9901 where the argument is EMACS_INT, and this behavior is not intended.
9902 * chartab.c (Fmake_char_table, Fset_char_table_range)
9903 (uniprop_get_decoder, uniprop_get_encoder):
9904 Don't assume fixnum fits in int.
9905 * cmds.c (move_point): New function, that does the gist of
9906 Fforward_char and Fbackward_char, but does so while checking
9907 for integer overflow more accurately.
9908 (Fforward_char, Fbackward_char): Use it.
9909 (Fforward_line, Fend_of_line, internal_self_insert)
9910 (internal_self_insert):
9911 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9912 Fix a FIXME, by checking for integer overflow when calculating
9913 target_clm and actual_clm.

9945 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9946 (consume_chars): Rewrite to not calculate an address outside buffer.
9947 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
9948 Don't access memory outside of the args array.
9949 (Fdefine_coding_system_internal): Check for charset-id overflow.
9950 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
9951 result of ENCODE_CHAR.
9952 * coding.h: Adjust decls to match defn changes elsewhere.

10643 * xgselect.c (xg_select): Fix first argument in call to 'select'
10646 2012-05-20 Ken Brown <kbrown@cornell.edu>
10648 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
10649 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
10651 2012-05-19 Ken Brown <kbrown@cornell.edu>
10653 * xfns.c (x_in_use): Remove `static' qualifier.
10654 * xterm.h (x_in_use): Declare.
10655 * xgselect.c: Include xterm.h.
10656 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
10657 and `display_arg' (bug#9754).
10659 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
10661 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
10663 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
10664 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
10666 2012-05-18 Eli Zaretskii <eliz@gnu.org>
10668 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
10670 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
10671 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
10673 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
10674 reference to image_cache->refcount.
10675 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10677 2012-05-17 Juri Linkov <juri@jurta.org>
10679 * search.c (Fword_search_regexp, Fword_search_backward)
10680 (Fword_search_forward, Fword_search_backward_lax)
10681 (Fword_search_forward_lax): Move functions to isearch.el
10682 (bug#10145, bug#11381).
10684 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10686 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10688 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10690 * lread.c (init_obarray): Declare Qt and Qnil as special.
10692 2012-05-14 Glenn Morris <rgm@gnu.org>
10694 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10695 Put "libexec" before "bin", for the sake of init_callproc_1.
10697 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10699 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10701 * unexaix.c: Port to more-recent AIX compilers.
10702 (report_error, report_error_1, make_hdr, copy_sym)
10703 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10704 Make arguments const char *, not char *, to avoid violations of C
10705 standard and to fix some AIX warnings reported by Gilles Pion.
10707 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10709 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10710 already have overlays loaded.
10711 (handle_single_display_spec): Before returning without displaying
10712 fringe bitmap, synchronize the bidi iterator with the main display
10713 iterator, by calling iterate_out_of_display_property.
10714 (iterate_out_of_display_property): Detect buffer iteration by
10715 testing that it->string is a Lisp string.
10716 (get_next_display_element): When the current object is exhausted,
10717 and there's something on it->stack, call set_iterator_to_next to
10718 proceed with what's on the stack, instead of returning zero.
10719 (set_iterator_to_next): If called at the end of a Lisp string,
10720 proceed to consider_string_end without incrementing string
10721 position. Don't increment display vector index past the end of
10722 the display vector. (Bug#11417)
10723 (pos_visible_p): Don't report a position visible when move_it_to
10724 stopped at the last line of window, which happens to be scanned
10725 backwards by the bidi iteration. (Bug#11464)
10727 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10729 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10730 and right-margin display specs even if the spec is invalid or we
10731 are on a TTY, and thus unable to display on the fringes.
10732 That's because the text with the property will not be displayed anyway,
10733 so we need to signal to the caller that this is a "replacing"
10734 display spec. This fixes display when the spec is invalid or we
10737 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10739 * unexaix.c (make_hdr): Fix typo in prototype.
10740 This bug broke the build on AIX. Problem reported by Gilles Pion.
10742 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10744 * keyboard.c (kbd_buffer_get_event): Read special events also in
10745 batch mode. (Bug#11415)
10747 2012-05-12 Glenn Morris <rgm@gnu.org>
10749 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10751 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10753 * lisp.mk (lisp): Add newcomment.elc.
10755 2012-05-12 Glenn Morris <rgm@gnu.org>
10757 * Makefile.in (MKDIR_P): New, set by configure.
10758 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10760 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10762 Remove unused function hourglass_started.
10763 * dispextern.h (hourglass_started):
10764 * w32fns.c (hourglass_started):
10765 * xdisp.c (hourglass_started): Remove.
10767 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10769 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10770 Update dependencies.
10772 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10774 * xgselect.c (xg_select): Put maxfds+1 into a var.
10775 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10777 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10779 2012-05-10 Dave Abrahams <dave@boostpro.com>
10781 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10782 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10784 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10786 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10787 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
10788 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10789 Initialize xd_registered_buses.
10791 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10793 Untag more efficiently if USE_LSB_TAG.
10794 This is based on a proposal by YAMAMOTO Mitsuharu in
10795 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10796 For an admittedly artificial (nth 8000 longlist) benchmark on
10797 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10798 Emacs's overall text size by 1%.
10799 * lisp.h (XUNTAG): New macro.
10800 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10801 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10802 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10803 * eval.c (Fautoload):
10804 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10805 * frame.h (XFRAME): Use XUNTAG.
10807 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10808 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10809 Remove unportable assumptions about print widths of types like
10811 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10812 intptr_t when converting between pointer and integer, to avoid GCC
10813 warnings about wrong width.
10815 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10817 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10818 stack for each reader_thread, instead of defaulting to 8MB
10819 determined by the linker. This avoids failures in creating
10820 subprocesses on Windows 7, see the discussion in this thread:
10821 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10823 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10825 Fix up display of the *Minibuf-0* buffer in the mini window.
10826 * keyboard.c (read_char): Don't clear the echo area if there's no
10828 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10829 contents of *Minibuf-0*) if there's no message displayed in its stead.
10831 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10833 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10836 2012-05-06 Chong Yidong <cyd@gnu.org>
10838 * lisp.mk (lisp): Update.
10840 2012-05-05 Jim Meyering <meyering@redhat.com>
10842 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10844 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10846 * data.c (PUT_ERROR): New macro.
10847 (syms_of_data): Use it. Add new error type `user-error'.
10848 * undo.c (user_error): New function.
10849 (Fprimitive_undo): Use it.
10850 * print.c (print_error_message): Adjust print style for `user-error'.
10851 * keyboard.c (user_error): New function.
10852 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10854 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10856 Do not limit current-time-string to years 1000..9999.
10857 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10858 (Fcurrent_time_string): Support any year that is supported by the
10859 underlying localtime representation. Don't use asctime, as it
10860 has undefined behavior for years outside the range -999..9999.
10862 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10864 Fix race conditions involving setenv, gmtime, localtime, asctime.
10865 Without this fix, interrupts could mess up code that uses these
10866 nonreentrant functions, since setting TZ invalidates existing
10867 tm_zone or tzname values, and since most of these functions return
10868 pointers to static storage.
10869 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10870 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10871 Grow the critical sections to include not just invoking
10872 localtime/gmtime, but also accessing these functions' results
10873 including their tm_zone values if any, and any related TZ setting.
10874 (format_time_string): Last arg is now struct tm *, not struct tm **,
10875 so that the struct tm is saved in the critical section.
10876 All callers changed. Simplify allocation of initial buffer, partly
10877 motivated by the fact that memory allocation needs to be outside
10878 the critical section.
10880 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10882 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10883 with RESET_INTERVAL.
10885 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10886 Remove duplicated buffer name initialization.
10888 2012-05-02 Jim Meyering <jim@meyering.net>
10890 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10892 * xfns.c (x_window): Use xstrdup (Bug#11375).
10894 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10896 * xdisp.c (pos_visible_p): If already at a newline from the
10897 display string before the 'while' loop, don't walk back the glyphs
10898 from it3.glyph_row. Solves assertion violation when the display
10899 string begins with a newline (egg.el). (Bug#11367)
10901 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10903 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10906 2012-05-01 Glenn Morris <rgm@gnu.org>
10908 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10909 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10910 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10911 All were removed before 23.1.
10913 * dispnew.c: Remove HAVE_LIBNCURSES test;
10914 it is always true on relevant platforms.
10916 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10917 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10919 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10921 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10923 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10924 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10927 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10929 Do not avoid creating empty evaporating overlays (Bug#9642).
10930 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10931 That is, do not delete an evaporating overlay if it becomes
10932 empty after its bounds are adjusted to fit within its buffer.
10933 This fix caused other problems, and I'm reverting it until we get
10934 to the bottom of them.
10936 2012-04-27 Chong Yidong <cyd@gnu.org>
10938 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10940 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10942 * xdisp.c (pos_visible_p): If the window start position is beyond
10943 ZV, start the display from buffer beginning. Prevents assertion
10944 violation in init_iterator when the minibuffer window is scrolled
10945 via the scroll bar.
10947 * window.c (window_scroll_pixel_based): Likewise.
10949 2012-04-27 Chong Yidong <cyd@gnu.org>
10951 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10953 2012-04-27 Glenn Morris <rgm@gnu.org>
10955 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10956 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10958 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10960 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10961 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10963 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10965 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10966 display element, check also the underlying string or buffer
10967 character. (Bug#11341)
10969 * w32menu.c: Include w32heap.h.
10970 (add_menu_item): If the call to AppendMenuW (via
10971 unicode_append_menu) fails, disable Unicode menus only if we are
10972 running on Windows 9X/Me.
10974 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10976 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10977 (xgetint): Add missing shift for LSB tags.
10979 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10981 * keyboard.c (read_char): Don't wipe echo area for select window
10982 events: These might get delayed via `mouse-autoselect-window'
10985 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10987 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10988 manipulation of :loaded-from data.
10990 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10992 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10993 now a cons (bug#11311).
10995 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10997 Do not create empty overlays with the evaporate property (Bug#9642).
10998 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10999 if it becomes empty after its bounds are adjusted to fit within
11000 its buffer. Without this fix, in a nonempty buffer (let ((o
11001 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11002 yields an empty overlay that has the evaporate property, which is
11003 not supposed to happen.
11005 Fix minor GTK3 problems found by static checking.
11006 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11007 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11008 (struct _EmacsFixedClass, emacs_fixed_get_type):
11009 Move decls here from emacsgtkfixed.h, since they needn't be public.
11010 (emacs_fixed_get_type): Now static.
11011 (emacs_fixed_class_init): Omit unused local.
11012 (emacs_fixed_child_type): Remove; unused.
11013 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11014 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11015 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11016 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11017 (EMACS_FIXED_GET_CLASS): Remove; unused.
11018 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11020 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11021 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11023 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11025 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11026 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11027 (__malloc_size_t, __malloc_ptrdiff_t):
11028 Remove. All uses removed, replaced by the definiens if needed,
11029 since we can assume C89 or better now.
11030 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
11031 (protect_malloc_state, align, get_contiguous_space)
11032 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

11035 (_malloc_internal_nolock, _malloc_internal, malloc, _malloc)
11036 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
11037 (special_realloc, _realloc_internal_nolock, _realloc_internal)
11038 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11039 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11040 Define using prototypes, not old style.
11041 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11042 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11043 (align): Don't assume that signed integer overflow wraps around.
11044 Omit unused local var.
11045 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11046 (_free_internal_nolock, memalign, mallochook, reallochook):
11047 Omit no-longer-needed casts.
11048 (valloc): Use getpagesize, not __getpagesize.
11049 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11050 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11052 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11054 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11056 Move functions from C to Lisp. Make non-blocking method calls
11057 the default. Implement further D-Bus standard interfaces.
11059 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
11060 (QCdbus_request_name_allow_replacement)
11061 (QCdbus_request_name_replace_existing)

11068 (QCdbus_registered_signal): New Lisp objects.
11069 (XD_DEBUG_MESSAGE): Use sizeof.

11072 (XD_DBUS_VALIDATE_BUS_NAME, XD_DBUS_VALIDATE_PATH)
11073 (XD_DBUS_VALIDATE_INTERFACE, XD_DBUS_VALIDATE_MEMBER): New macros.
11074 (XD_CHECK_DBUS_SERIAL): Rename from CHECK_DBUS_SERIAL_GET_SERIAL.
11075 (xd_signature, xd_append_arg): Allow float for integer types.
11076 (xd_get_connection_references): New function.
11077 (xd_get_connection_address): Rename from xd_initialize.
11078 Return cached address.

11118 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11120 * sysdep.c [__FreeBSD__]: Minor cleanups.
11121 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11122 Use Emacs indenting style more consistently. Avoid some casts.

11127 * sysdep.c (list_system_processes, system_process_attributes):
11128 Add implementation for FreeBSD (Bug#5243).

11134 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11136 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11137 It is never used otherwise.
11139 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11141 * print.c (print_preprocess): Only check print_depth if print-circle
11143 (print_object): Check for cycles even when print-circle is nil and
11144 print-gensym is t, but only check print_depth if print-circle is nil.

11148 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11149 set the status to "failed" and ensure that sentinel is run.
11151 2012-04-20 Glenn Morris <rgm@gnu.org>
11153 * process.c (Fset_process_inherit_coding_system_flag)
11154 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11164 farther than the first row after the header line, if any.
11165 Don't consider the header-line row as "partially visible", even if
11166 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
11168 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

11182 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11183 -Wunused-result, -Wunused-variable. This should go away once
11184 the Emacs and Gnulib regex code is merged.
11185 (xmalloc, xrealloc): Now static.
11187 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

11204 New extern decls, to avoid calling undeclared functions.
11205 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11206 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11207 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11208 (NEED_MEM_INSERT): New macro.
11209 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11210 Remove one incorrect comment and fix another.

11225 Remove decls. This fixes an "It stinks!".
11227 * alloc.c (which_symbols): Fix alignment issue / type clash.
11229 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11231 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

11246 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11247 * s/netbsd.h, s/sol2-6.h:
11248 Remove definition of GC_MARK_STACK, since the default now works.
11249 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

11252 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11254 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11256 * lread.c (lisp_file_lexically_bound_p):

11275 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11277 2012-04-11 Daniel Colascione <dancol@dancol.org>
11279 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11280 against is gone. It's better to use vfork now so that when Cygwin
11281 gains a new, working vfork, we use it automatically (bug#10398).
11283 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11303 * w32.c (w32_delayed_load): Record the full path of the library
11304 being loaded (bug#10424).
11306 2012-04-09 Glenn Morris <rgm@gnu.org>
11308 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11309 not just in the obarray, before snarfing them. (Bug#11036)

11326 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11327 attempts per process (connection).
11329 2012-04-09 Chong Yidong <cyd@gnu.org>
11331 * eval.c (Fuser_variable_p, user_variable_p_eh)

11333 (Fdefvar): Caller changed.
11335 * callint.c (Finteractive, Fcall_interactively):
11336 * minibuf.c (Fread_variable): Callers changed.
11338 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11340 * xdisp.c (set_cursor_from_row): If the display string appears in
11341 the buffer at position that is closer to point than the position
11342 after the display string, display the cursor on the first glyph of
11343 the display string. Fixes cursor display when a 'display' text
11344 property immediately follows invisible text. (Bug#11094)
11346 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11348 composite.c: use 'double' consistently
11349 * composite.c (get_composition_id): Use 'double' consistently
11350 instead of converting 'float' to 'double' and vice versa; this is
11351 easier to understand and avoids a GCC warning.
11353 2012-04-09 Glenn Morris <rgm@gnu.org>
11355 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11356 preparation for dumping it with emacs. (Bug#4789)

11378 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11379 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11380 objects, as mark_maybe_pointer will catch them otherwise.

11395 ($(BLD)/xml.$(O)): New dependency list.
11397 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11398 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11399 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11400 [!WINDOWSNT]: New macros.
11401 (init_libxml2_functions, libxml2_loaded_p): New functions.
11402 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11403 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11404 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11405 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11407 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11408 Call init_libxml2_functions before calling libxml2 functions.
11409 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11411 * emacs.c: Don't include libxml/parser.h.
11412 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11413 xmlCleanupParser directly.

11417 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11419 * indent.c (Fvertical_motion): If there is a display string at
11420 point, use it.vpos to compute how many lines to backtrack after
11421 move_it_to point. (Bug#11133)
11423 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11425 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11426 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11427 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11428 macros related to unification of CJK characters. For the details,
11429 see the discussion following the message here:
11430 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11432 2012-04-04 Chong Yidong <cyd@gnu.org>
11434 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11436 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11438 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

11446 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11448 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11449 position we get to after a call to move_it_to fails the
11450 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11451 only if we wind up in a string from display property. (Bug#11063)
11453 * window.c (Fdelete_other_windows_internal): Invalidate the row
11454 and column information about mouse highlight, so that redisplay
11455 restores it after reallocating the glyph matrices. (Bug#7464)
11457 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11458 string comes from a `display' text property, use the buffer
11459 position of that property as if we actually saw that position in
11461 (move_it_by_lines): Remove the assertion that
11462 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11463 violated when there's a before-string at the beginning of a line.
11466 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11468 * xdisp.c (append_space_for_newline): If the default face was
11469 remapped, use the remapped face for the appended newline.
11470 (extend_face_to_end_of_line): Use the remapped default face for
11471 extending the face to the end of the line.
11472 (display_line): Call extend_face_to_end_of_line when the default
11473 face was remapped. (Bug#11068)
11475 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11477 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11479 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

11483 2012-03-27 Glenn Morris <rgm@gnu.org>
11485 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11488 2012-03-26 Kenichi Handa <handa@m17n.org>

11495 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11496 (command_loop_1): Use it; inhibit selection update for

11501 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11503 2012-03-25 Kenichi Handa <handa@m17n.org>
11505 * dispextern.h (struct glyph): Change the bit length of
11506 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11508 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11510 * s/ms-w32.h (tzname): Include time.h before redirecting to

11519 !SYNC_INPUT. (Bug#11080)
11521 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11523 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11524 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11525 when fetching a multibyte character consumes more bytes than
11526 CHAR_BYTES returns, due to unification of CJK characters in
11527 string_char. (Bug#11073)
11529 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11531 * process.c (wait_reading_process_output): Handle pty disconnect

11561 it fit in a valid range (Bug#11003).
11563 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11565 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11566 that is not from display property, accept the row as a "cursor
11567 row" if one of the string's character has a non-nil `cursor'
11568 property. Fixes cursor positioning when there are newlines in
11569 overlay strings, e.g. in icomplete.el. (Bug#11035)
11571 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

11622 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11624 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11625 push_it before setting up the iterator for the first overlay
11626 string, even if we have an empty string loaded.
11627 (next_overlay_string): If there's an empty string on the iterator
11628 stack, pop the stack. (Bug#10903)
11630 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11632 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11633 Suggested by Stefan Monnier in
11634 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11635 * alloc.c (widen_to_Lisp_Object): New static function.
11636 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11637 and widening them to Lisp_Objects. This would work even if
11638 USE_LSB_TAG is defined and wide integers are used, which might
11639 happen in a future version of Emacs.
11641 2012-02-25 Chong Yidong <cyd@gnu.org>
11643 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

11648 before saving to clipboard manager.
11650 2012-02-24 Chong Yidong <cyd@gnu.org>
11652 * keyboard.c (process_special_events): Handle all X selection
11653 requests in kbd_buffer, not just the next one (Bug#8869).
11655 2012-02-23 Chong Yidong <cyd@gnu.org>
11657 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11658 call when setting menu-bar-lines and tool-bar-lines parameters.
11659 (unwind_create_frame_1): New helper function.

11680 when computing $valmask.
11682 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11683 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11684 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11685 It's useless in that case, and it can cause problems on hosts
11686 that allocate halves of EMACS_INT values separately.
11687 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11688 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11689 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11690 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11691 it avoids undefined behavior on hosts where shifting right by more
11692 than the word width has undefined behavior.
11694 2012-02-19 Chong Yidong <cyd@gnu.org>
11696 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11697 (Funhandled_file_name_directory, Ffile_name_as_directory)
11698 (Fdirectory_file_name, Fexpand_file_name)
11699 (Fsubstitute_in_file_name): Protect against invalid file handler
11700 return values (Bug#10845).

11716 2012-02-15 Chong Yidong <cyd@gnu.org>
11718 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11719 marked as special. Also, starting docstrings with * is obsolete.

11734 2012-02-12 Chong Yidong <cyd@gnu.org>
11736 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11737 as that creates a dangerous corner case.
11739 * window.c (Fdelete_window_internal): Invalidate the mouse
11740 highlight (Bug#9904).
11742 2012-02-12 Glenn Morris <rgm@gnu.org>

11747 * nsselect.m (Fx_own_selection_internal)
11748 (Fx_disown_selection_internal, Fx_selection_exists_p)
11749 (Fx_selection_owner_p, Fx_get_selection_internal):
11750 Sync docs and argument specs with the xselect.c versions.
11752 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

11772 2012-02-07 Chong Yidong <cyd@gnu.org>
11774 * buffer.c (Fbuffer_local_variables)
11775 (buffer_lisp_local_variables): Handle unbound vars correctly;
11776 don't let Qunbound leak into Lisp.
11778 2012-02-07 Glenn Morris <rgm@gnu.org>
11780 * image.c (Fimagemagick_types): Doc fix.
11782 * image.c (imagemagick-render-type): Change it from a lisp object
11783 to an integer. Move the doc here from the lisp manual.

11800 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11802 * w32.c (get_emacs_configuration_options):
11803 Include --enable-checking, if specified, in the return value.

11817 Handle overflow when computing char display width (Bug#9496).
11818 * character.c (char_width): Return EMACS_INT, not int.
11819 (char_width, c_string_width): Check for overflow when
11820 computing the width; this is possible now that individual
11821 characters can have unbounded width. Problem introduced
11822 by merge from Emacs 23 on 2012-01-19.

11846 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11848 (x_produce_glyphs): If the component of a composition is a null

11853 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11854 first 2 arguments are identical. This makes inserting large
11855 output from a subprocess an order of magnitude faster on
11856 MS-Windows, where all sbrk'ed memory is always contiguous.
11858 2012-01-31 Glenn Morris <rgm@gnu.org>

11953 2012-01-09 Eli Zaretskii <eliz@gnu.org>
11955 * xdisp.c (rows_from_pos_range): Accept additional argument
11956 DISP_STRING, and accept any glyph in a row whose object is that
11957 string as eligible for mouse highlight. Fixes mouse highlight of
11958 display strings from overlays. (Bug#10464)
11960 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
11962 emacs: fix an auto-save permissions race condition (Bug#10400)

11964 (Fmake_directory_internal): Use it.
11965 (do_auto_save_make_dir): Set it, instead of invoking chmod after

12471 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
12472 Otherwise, valgrind does not work on some platforms.
12473 Problem reported by Andreas Schwab in
12474 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12475 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12476 is set, removing the need for VIRT_ADDRESS_VARIES.
12477 (PURE_P): Use a more-efficient implementation that needs just one
12478 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12479 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12480 to 4 (xorl, subq, cmpq, setbe).
12481 * alloc.c (pure): Always extern now, since that's the
12482 VIRT_ADDR_VARIES behavior.
12483 (PURE_POINTER_P): Use a single comparison, not two, for
12484 consistency with the new puresize.h.
12485 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

12946 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
12948 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
12950 2011-10-28 Eli Zaretskii <eliz@gnu.org>
12952 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
12953 <oslsachem@gmail.com> for helping to debug this.
12955 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
12956 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
12957 (g_b_init_get_glyph_outline_w): New static variables.
12958 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
12959 (GetGlyphOutlineW_Proc): New typedefs.
12960 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
12961 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
12963 (w32font_open_internal, compute_metrics):
12964 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12965 instead of calling the "wide" APIs directly.
12967 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
12969 * w32.h (syms_of_w32font): Add prototype.
12971 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12973 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
12974 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
12975 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
12976 (Fmove_to_window_line): Doc fix.
12978 2011-10-27 Chong Yidong <cyd@gnu.org>
12980 * process.c (make_process): Set gnutls_state to NULL.
12982 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
12983 non-NULL, regardless of GNUTLS_INITSTAGE.
12984 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
12985 an error. Set process slots as soon as we allocate them.
12987 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
12989 2011-10-27 Chong Yidong <cyd@gnu.org>
12991 * gnutls.c (emacs_gnutls_deinit): New function.
12992 Deallocate credentials structures as well as calling gnutls_deinit.
12993 (Fgnutls_deinit, Fgnutls_boot): Use it.
12995 * process.c (make_process): Initialize GnuTLS credentials to NULL.
12996 (deactivate_process): Call emacs_gnutls_deinit.
12998 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13000 * image.c (x_create_x_image_and_pixmap):
13001 * w32.c (sys_rename, w32_delayed_load):
13002 * w32font.c (fill_in_logfont):
13003 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13005 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13007 * w32fns.c (w32_default_color_map): New function,
13008 extracted from Fw32_default_color_map.
13009 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13011 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13013 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13015 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13017 * keyboard.c (test_undefined): New function (bug#9751).
13018 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13020 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13022 * sysdep.c (init_sys_modes): Fix the check for the controlling
13023 terminal (Bug#6649).
13025 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13027 * dispextern.h (struct bidi_it): New member next_en_type.
13029 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13030 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13031 current character, check also for next_en_type being WEAK_EN.
13032 (bidi_resolve_weak): Don't enter the expensive loop if the current
13033 position is before next_en_pos. Record the bidi type of the first
13034 non-ET, non-BN character we find, in addition to its position.
13035 (bidi_level_of_next_char): Invalidate next_en_type when
13036 next_en_pos is over-stepped.
13038 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13040 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13041 * editfns.c: Rewrite current-time-zone so that it invokes
13042 the equivalent of (format-time-string "%Z") to get the time zone name.
13043 This fixes a bug when the time zone name contains characters that
13044 need converting from the system time locale to Emacs internal format.
13045 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13046 that patch fixed format-time-string to do the conversion, but
13047 I forgot to fix current-time-zone.
13048 (format_time_string): New function, containing most of
13049 what Fformat_time_string used to contain.
13050 (Fformat_time_string): Rewrite in terms of format_time_string.
13051 This doesn't change this function's behavior.
13052 (current-time-zone): Rewrite to use format_time_string.
13053 This fixes the bug reported by Michael Schierl in
13054 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13055 Jason Rumney's 2007-06-07 change worked around this bug, but
13057 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13059 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13061 * xdisp.c (start_display): If the character at POS is displayed
13062 via a display vector, reset IT->current.dpvec_index to zero.
13063 (try_window_reusing_current_matrix): If a line ends in a display
13064 vector or the next line starts in a display vector, continue
13065 redrawing the window even though the character position of
13066 start_row was reached.
13069 2011-10-18 Chong Yidong <cyd@gnu.org>
13071 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13072 with nobreak-char-display too.
13074 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13076 Fix part 3 of bug#9771.
13077 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13078 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13079 non-neutral characters if the current character is a paragraph
13080 separator (a.k.a. Newline). This avoids running the same
13081 expensive loop twice, once when we consume the preceding newline
13082 and the other time when the line actually needs to be displayed.
13083 Avoid the loop when we see neutrals on the base embedding level
13084 following a character whose directionality is the same as the
13085 paragraph's. This avoids running the expensive loop when a line
13086 ends in a long sequence of neutrals, like control characters.
13087 Add assertion against STRONG_AL type. Slightly rearrange code
13088 that determines the type of a neutral given the first non-neutral
13090 (bidi_level_of_next_char): Set next_en_pos to zero when
13091 invalidating its info.
13093 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13095 * xdisp.c (push_display_prop): Determine whether to record string
13096 or buffer position by IT->string, not by IT->method. Allow
13097 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13098 (move_it_vertically_backward): Don't look for character position
13099 immediately after the newline when in a continuation line.
13102 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13104 * window.c (coordinates_in_window): Rewrite and delabelize
13105 vertical border check. (Bug#5357) (Bug#9618)
13107 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13109 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13110 errors in XSetWindowBorder (bug#9310).
13112 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13114 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13115 avoid crash when xmalloc overrun checking is enabled.
13117 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13119 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13120 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13121 cursor motion with <left> and <right> arrow keys.
13123 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13124 some callers set that themselves.
13126 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13128 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13129 display string and the previous row comes from the same string and
13130 is empty. (Bug#9739) (Bug#9738)
13132 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13134 * doc.c (get_doc_string): Encode file name (bug#9735).
13136 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13138 * bidi.c (bidi_level_of_next_char):
13139 * xdisp.c (get_visually_first_element): Remove old incorrect
13140 comments regarding the Unicode Line Separator character.
13142 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13144 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13146 * alloc.c (Fgc_status): Do not access beyond zombies array
13147 boundary if nzombies > MAX_ZOMBIES.
13148 * alloc.c (dump_zombies): Add missing format specifier.
13150 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13152 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13153 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13155 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13156 Some packages use them to denote characters with modifiers.
13158 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13160 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13161 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13162 matching a pp-number. Rename parameter var to var1.
13164 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13166 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13168 2011-10-08 Glenn Morris <rgm@gnu.org>
13170 * callint.c (Fcall_interactively): Give a more explicit error for the
13171 'c' case with a non-character input. (Bug#8479)
13173 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13175 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13177 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13178 lines that are hscrolled on the left.
13180 * dispnew.c (buffer_posn_from_coords): Account for a possible
13181 presence of header-line. (Bug#4426)
13183 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13185 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13186 Don't advertise functionality which we discourage or doesn't work.
13188 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13190 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13191 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13192 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13193 this makes Emacs dump core during garbage collection on rare
13194 occasions. sizeof is obviously inferior to offsetof here, so
13195 stick with offsetof.
13196 (GC_POINTER_ALIGNMENT): New macro.
13197 (mark_memory): Omit 3rd (offset) arg; caller changed.
13198 Don't assume EMACS_INT alignment is the same as pointer alignment.
13200 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13202 * keyboard.c (read_key_sequence_remapped): New var.
13203 (read_key_sequence): Compute remapping in the right buffer.
13204 (command_loop_1): Use read_key_sequence's remapping directly.
13206 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13208 * dired.c (file_name_completion): Don't expand file name.
13209 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13210 before checking file name handler.
13212 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13213 they've been requested explicitly (bug#9591).
13215 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13217 * keymap.c (Fsingle_key_description): Use make_specified_string
13218 instead of build_string to build string from push_key_description.
13221 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13223 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13224 This fixes a Y2038 bug on 64-bit hosts.
13225 * buffer.c (reset_buffer):
13226 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13227 (Fclear_buffer_auto_save_failure):
13228 Use 0, not -1, to represent an unset failure time, since time_t
13229 might not be signed.
13231 Remove dependency on glibc malloc internals.
13232 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13233 Move back here from lisp.h, but with their new implementations.
13234 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13235 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13236 * charset.c (charset_table_init): New static var.
13237 (syms_of_charset): Use it instead of xmalloc. This removes a
13238 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13239 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13240 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13241 Move back to alloc.c.
13242 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13243 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13245 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13247 * nsterm.m (windowDidResize): Call x_set_window_size only when
13248 ns_in_resize is true. Otherwise set pixelwidth/height and
13249 call change_frame_size (Bug#9628).
13251 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13253 Port --enable-checking=all to Fedora 14 x86-64.
13254 * charset.c (syms_of_charset): Also account for glibc malloc's
13255 internal overhead when calculating the initial malloc maximum.
13257 Port --enable-checking=all to Fedora 14 x86.
13258 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13260 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13261 (overrun_check_realloc, overrun_check_free):
13262 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13263 That way, xmalloc returns a properly-aligned pointer even if
13264 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13265 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13266 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13267 into account when calculating the initial malloc maximum.
13268 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13269 Move here from alloc.c, so that charset.c can use it too.
13270 Properly align; the old code wasn't right for common 32-bit hosts
13271 when configured with --enable-checking=all.
13272 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13273 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13275 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13277 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13280 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13282 * xdisp.c (compute_display_string_end): If there's no display
13283 string at CHARPOS, return -1.
13285 * bidi.c (bidi_fetch_char): When compute_display_string_end
13286 returns a negative value, treat the character as a normal
13287 character not covered by a display string. (Bug#9624)
13289 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13291 * lread.c (Fread_from_string): Fix typo in docstring.
13293 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13295 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13296 newline, reseat the iterator instead of bidi-iterating there one
13297 character at a time. (Bug#9610)
13298 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13299 TO_CHARPOS if the bidi iterator is at base embedding level.
13301 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13303 * lread.c (readevalloop): Use correct code for NBSP.
13304 (read1): Likewise. (Bug#9608)
13306 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13308 * dbusbind.c (Fdbus_register_signal): When service is not
13309 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13311 2011-09-25 Glenn Morris <rgm@gnu.org>
13313 * buffer.c (truncate-lines): Doc fix.
13315 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13317 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13318 (Fset_window_next_buffers): Doc fix.
13320 2011-09-24 Glenn Morris <rgm@gnu.org>
13322 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13324 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13326 Fix minor problems found by static checking.
13327 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13328 * indent.c (Fvertical_motion): Fix == vs = typo.
13330 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13332 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13333 Default value is now t. Doc fix.
13335 * indent.c (Fvertical_motion): Compute and apply the overshoot
13336 logic when moving up, not only when moving down. Fix the
13337 confusing name and values of the it_overshoot_expected variable;
13338 logic changes accordingly. (Bug#9254) (Bug#9549)
13340 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13341 CHARPOS is covered by a display string which includes newlines.
13342 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13343 is covered by a display string with embedded newlines.
13345 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13347 * dbusbind.c (Fdbus_register_signal): Add match rule to
13348 Vdbus_registered_objects_table. (Bug#9581)
13349 (Fdbus_register_method, Vdbus_registered_objects_table):
13352 2011-09-24 Jim Meyering <meyering@redhat.com>
13354 do not ignore write error for any output size
13355 The previous change was incomplete.
13356 While it makes emacs --batch detect the vast majority of stdout
13357 write failures, errors were still ignored whenever the output size is
13358 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13359 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13360 && echo FAIL: ignored write error
13361 FAIL: ignored write error
13362 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13363 && echo FAIL: ignored write error
13364 FAIL: ignored write error
13365 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13367 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13369 * emacs.c (Fkill_emacs): In noninteractive mode exit
13370 non-successfully if a write error occurred on stdout. (Bug#9574)
13372 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13374 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13377 * dispextern.h (struct it): Update the comment documenting what
13380 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13382 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13383 a display string, extend search for cursor position to end of row.
13384 (find_row_edges): If the row ends in a newline from a display
13385 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13386 Handle the case of a display string with multiple newlines.
13387 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13388 non-empty line. Fixes confusing cursor motion with arrow keys at
13389 the beginning of a line that starts with whitespace.
13391 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13393 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13396 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13398 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13399 boolean (Bug#9154).
13401 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13403 * xdisp.c (display_line): Record maximum and minimum buffer
13404 positions even if no glyphs were produced (e.g., by a zero-width
13405 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13406 buffer positions that will be removed from the glyph row because
13408 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13409 column is beyond frame width: don't subtract 1 "pixel" when
13410 computing width of the stretch.
13411 (reseat_at_next_visible_line_start): Undo the change made on
13412 2011-09-17 that saved paragraph information and restored it after
13413 the call to `reseat'. (Bug#9545)
13415 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13417 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13418 and turn window cursor on if cleared (Bug#9415).
13420 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13422 * search.c (boyer_moore): Take unibyte characters from pattern
13423 literally. (Bug#9458)
13425 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13427 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13429 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13431 Fix minor problem found by static checking.
13432 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13433 initialized, to pacify gcc -Wuninitialized.
13435 * fileio.c: Report proper errno when syscall falls.
13436 (Finsert_file_contents): Save and restore errno,
13437 so that report_file_error outputs the correct diagnostic.
13438 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13440 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13442 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13444 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13446 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13447 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13449 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13451 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13452 about the current paragraph and restore it after the call to reseat.
13454 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13455 (bidi_find_paragraph_start): Search back for paragraph beginning
13456 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13457 (bidi_move_to_visually_next): Only trigger paragraph-related
13458 computations when the last character is a newline or at EOB, not
13459 just any NEUTRAL_B. (Bug#9470)
13461 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13462 truncated lines if point is covered by a display string. (Bug#9524)
13464 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13466 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13467 (cons_to_x_long): New function.
13468 (lisp_data_to_selection_data): Use it. Correct the test for
13469 short-versus-long data; it was negated. Break out of vector
13470 loop, for efficiency, when a long datum is discovered.
13472 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13474 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13476 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13478 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13479 GCC PR/17406) by declaring this function with external scope.
13481 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13483 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13484 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13486 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13488 * editfns.c (Fformat): Correctly handle text properties on "%%".
13490 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13492 * xterm.c (x_draw_composite_glyph_string_foreground):
13493 * w32term.c (x_draw_composite_glyph_string_foreground):
13494 * term.c (encode_terminal_code):
13495 * composite.c (composition_update_it, get_composition_id):
13496 * xdisp.c (get_next_display_element)
13497 (fill_composite_glyph_string): Add comments about special meaning
13498 of TAB characters in a composition.
13500 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13502 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13503 This occurs when processing a multibyte format.
13504 Problem reported by Wolfgang Jenker.
13506 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13508 * xdisp.c (try_cursor_movement): Only check for exact match if
13509 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13511 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13513 Remove unused external symbols.
13514 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13515 * xdisp.c (calc_pixel_width_or_height): Now static.
13516 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13517 * indent.c (check_display_width):
13518 * w32term.c: Fix comment to match code.
13519 * xterm.c, xterm.h (x_catching_errors): Remove.
13521 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13523 * xselect.c: Use signed conversions more consistently (Bug#9498).
13524 (selection_data_to_lisp_data): Assume incoming selection data are
13525 signed integers, not unsigned. This is to be consistent with
13526 outgoing selection data, which was modified to use signed integers
13527 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13528 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13529 expects long, not unsigned long.
13531 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13533 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13534 computation of loop end. Reported by Johan Bockgård
13537 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13539 * frame.c (Fother_visible_frames_p): Function deleted.
13541 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13543 * indent.c (compute_motion): Process display vector front to back
13544 rather than the other way around. (Bug#2496)
13546 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13548 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13550 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13552 * minibuf.c (Fread_from_minibuffer): Doc fix.
13554 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13556 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13557 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13559 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13561 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13562 value for non-existent files.
13564 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13566 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13567 set its "size" to -1. This will set the modtime_size field of
13568 the corresponding buffer to -1, which is what
13569 verify-visited-file-modtime expects for files that do not exist.
13572 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13574 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13576 * lisp.h: ... from here. push_key_description is no longer
13577 defined in keyboard.c, so its declaration should not be in
13578 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13579 logically belongs with push_key_description.
13581 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13583 * buffer.h: Include <sys/types.h> instead of <time.h>.
13584 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13585 Problem reported by Herbert J. Skuhra.
13587 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13589 * xml.c (parse_region): Make the parsing work for
13590 non-comment-starting XML files again (bug#9144).
13592 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13594 * image.c (gif_load): Fix calculation of bottom and right corner.
13597 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13599 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13600 redisplay in small windows.
13602 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13604 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13606 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13608 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13609 Operate on live windows only.
13611 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13613 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13615 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13617 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13618 only under bidi iteration.
13620 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13622 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13624 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13626 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13627 Without this fix, the command to link temacs failed due to an
13628 undefined symbol __builtin_isnan. This is because
13629 /usr/include/iso/math_c99.h #defines isnan(x) to
13630 __builtin_isnan(x), but the bundled gcc, which identifies itself
13631 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13633 * floatfns.c (isnan): #undef, and then #define to a clone of
13635 (Fisnan): Always define, since it's always available now.
13636 (syms_of_floatfns): Always define isnan at the Lisp level.
13638 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13640 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13642 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13644 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13645 The previous code assumed that file offsets (off_t values) fit in
13646 EMACS_INT variables, which is not true on typical 32-bit hosts.
13647 The code messed up by falsely reporting buffer overflow in cases
13648 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13649 when "big" contains more than 2**29 bytes, even though this
13650 inserts just one byte and does not overflow the buffer.
13651 (Finsert_file_contents): Store file offsets as off_t
13652 values, not as EMACS_INT values. Check for overflow when
13653 converting between EMACS_INT and off_t. When checking for
13654 buffer overflow or for overlap, take the offsets into account.
13655 Don't use EMACS_INT for small values where int suffices.
13656 When checking for overlap, fix a typo: ZV was used where
13657 ZV_BYTE was intended.
13658 (Fwrite_region): Don't assume off_t fits into 'long'.
13659 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13661 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13663 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13665 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13667 sprintf-related integer and memory overflow issues (Bug#9412).
13669 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13670 (esprintf, exprintf, evxprintf): New functions.
13671 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13672 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13673 (modify_event_symbol): Do not assume that the length of
13674 name_alist_or_stem is safe to alloca and fits in int.
13675 (Fexecute_extended_command): Likewise for function name and binding.
13676 (Frecursion_depth): Wrap around reliably on integer overflow.
13677 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13678 since some callers pass EMACS_INT values.
13679 (Fsingle_key_description): Don't crash if symbol name contains more
13680 than MAX_ALLOCA bytes.
13681 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13682 (get_minibuffer): Arg is now EMACS_INT, not int.
13683 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13684 (esprintf, exprintf, evxprintf): New decls.
13685 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13687 * dbusbind.c (signature_cat): New function.
13688 (xd_signature, Fdbus_register_signal):
13689 Do not overrun buffer; instead, report string overflow.
13691 * dispnew.c (add_window_display_history): Don't overrun buffer.
13692 Truncate instead; this is OK since it's just a log.
13694 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13695 even if the time zone offset is outlandishly large.
13696 Don't mishandle offset == INT_MIN.
13698 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13699 when creating daemon; the previous buffer-overflow check was incorrect.
13701 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13702 which has the guts of the old verror function.
13704 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13705 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13707 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13708 (font_unparse_xlfd): Don't blindly alloca long strings.
13709 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13710 fits in int, when using sprintf. Use single snprintf to count
13711 length of string rather than counting it via multiple sprintfs;
13712 that's simpler and more reliable.
13713 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13714 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13715 sprintf, in case result does not fit in int.
13717 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13718 (fontset_from_font): Print it.
13720 * frame.c (tty_frame_count): Now printmax_t, not int.
13721 (make_terminal_frame, set_term_frame_name): Print it.
13722 (x_report_frame_params): In X, window IDs are unsigned long,
13723 not signed long, so print them as unsigned.
13724 (validate_x_resource_name): Check for implausibly long names,
13725 and don't assume name length fits in 'int'.
13726 (x_get_resource_string): Don't blindly alloca invocation name;
13727 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13730 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13731 (xg_check_special_colors, xg_set_geometry):
13732 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13734 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13735 Use esprintf, not sprintf, in case result does not fit in int.
13737 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13738 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13739 it as a large positive number.
13740 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13741 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13743 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13744 in case result does not fit in int.
13746 * print.c (float_to_string): Detect width overflow more reliably.
13747 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13748 buffer overrun. Don't assume list length fits in 'int'. Treat
13749 print length of 0 as 0, not as infinity; to be consistent with other
13750 uses of print length in this function. Don't overflow print length
13751 index. Don't assume hash table size fits in 'long', or that
13752 vectorlike size fits in 'unsigned long'.
13754 * process.c (make_process): Use printmax_t, not int, to format
13755 process-name gensyms.
13757 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13759 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13760 to avoid potential buffer overrun.
13762 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13763 if X resource line is longer than 512 bytes.
13765 * xfns.c (x_window): Make sprintf buffer a bit bigger
13766 to avoid potential buffer overrun.
13768 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13770 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13772 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13774 Integer overflow fixes for scrolling, etc.
13775 Without these, Emacs silently mishandles large integers sometimes.
13776 For example, "C-u 4294967297 M-x recenter" was treated as if
13777 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13779 * xdisp.c (try_window_id): Check Emacs fixnum range before
13780 converting to 'int'.
13782 * window.c (window_scroll_line_based, Frecenter):
13783 Check that an Emacs fixnum is in range before assigning it to 'int'.
13784 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13785 values converted from Emacs fixnums.
13786 (Frecenter): Don't wrap around a line count if it is out of 'int'
13787 range; instead, treat it as an extreme value.
13788 (Fset_window_configuration, compare_window_configurations):
13789 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13791 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13792 that can exceed INT_MAX. Check that EMACS_INT value is in range
13793 before assigning it to the (possibly-narrower) index.
13794 (match_limit): Don't assume that a fixnum can fit in 'int'.
13796 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13799 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13800 (Fvertical_motion): Don't wrap around LINES values that don't fit
13801 in 'int'. Instead, treat them as extreme values. This is good
13802 enough for windows, which can't have more than INT_MAX lines anyway.
13804 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13806 * Require libxml/parser.h to avoid compilation warning.
13808 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13810 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13811 since this reportedly can destroy thread storage.
13813 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13815 * syntax.c (find_defun_start): Update all cache variables if
13816 exiting early (Bug#9401).
13818 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13820 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13822 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13823 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13824 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13826 * term.c (tty_append_glyph): New function.
13827 (produce_stretch_glyph): Static function and its prototype deleted.
13829 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13832 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13834 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13835 when checking :margin (Bug#9390).
13836 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13837 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13838 so that the name doesn't mislead. All uses changed.
13840 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13842 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13845 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13847 * xdisp.c (move_it_to): Don't bail out early when reaching
13848 position beyond to_charpos, if we are scanning backwards.

13850 the first character in the line after the newline.
13852 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13854 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13855 (ccl_driver): Do not generate an out-of-range pointer.
13856 (Fccl_execute_on_string): Remove unnecessary check for
13857 integer overflow, noted by Stefan Monnier in
13858 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13859 Remove a FIXME that didn't need fixing.
13860 Simplify the newly-introduced buffer reallocation code.
13862 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13864 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13866 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13868 Integer and memory overflow issues (Bug#9196).
13870 * doc.c (get_doc_string): Rework so that
13871 get_doc_string_buffer_size is the actual buffer size, rather than
13872 being 1 less than the actual buffer size; this makes xpalloc more
13875 * image.c (x_allocate_bitmap_record, cache_image):
13876 * xselect.c (Fx_register_dnd_atom):
13877 Simplify previous changes by using xpalloc.
13879 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13880 since either will do and ptrdiff_t is convenient with xpalloc.
13882 * charset.c (charset_table_size)
13883 (struct charset_sort_data.priority): Now ptrdiff_t.
13884 (charset_compare): Don't overflow if priorities differ greatly.
13885 (Fsort_charsets): Don't assume list length fits in int.
13886 Check for size-calculation overflow when allocating sort data.
13887 (syms_of_charset): Allocate an initial charset table that is
13888 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13890 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13892 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13893 The actual value is always <= INT_MAX, and leaving it unsigned made
13894 overflow checking harder.
13896 * dispextern.h (struct glyph_matrix.rows_allocated)
13897 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13898 with xpalloc. The values are still always <= INT_MAX.
13900 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13902 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13903 (SAFE_NALLOCA): New macro.
13905 * region-cache.c (struct boundary.pos, find_cache_boundary)
13906 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13907 (set_cache_region, invalidate_region_cache)
13908 (revalidate_region_cache, know_region_cache, region_cache_forward)
13909 (region_cache_backward, pp_cache):
13910 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13911 so that ptrdiff_t * can be passed to xpalloc.
13912 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13913 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13914 (pp_cache): Don't assume cache_len fits in int.
13915 * region-cache.h: Adjust extern decls to match.
13917 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13918 EMACS_INT, since either will do, for xpalloc.
13920 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13921 (xnmalloc, xnrealloc, xpalloc): New functions.
13923 * bidi.c (bidi_shelve_header_size): New constant.
13924 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13925 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13927 * bidi.c (bidi_cache_shrink):
13928 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13930 Don't update size of array until after memory allocation succeeds,
13931 because xmalloc/xrealloc may not return.
13932 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13933 now that we have proper integer overflow checking.
13934 (record_overlay_string, overlay_strings): Catch overflows when
13935 calculating size of overlay_str_buf.
13937 * callproc.c (Fcall_process): Check for size overflow when
13938 calculating size of args2.
13939 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13940 Normally we prefer signed values, but sticking with ptrdiff_t would
13941 require adding more-complicated checks.
13943 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13944 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13945 Redo buffer-overflow calculations to avoid integer overflow.
13946 Add a FIXME comment where memory seems to be over-allocated.
13948 * character.c (Fstring): Check for size-calculation overflow.
13950 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13951 unnecessary integer overflow. Check for size overflow.
13952 (encode_coding_object): Don't update size until xmalloc succeeds.
13954 * composite.c (get_composition_id): Check for overflow in glyph
13955 length calculations.
13957 Integer and memory overflow fixes for display code.
13958 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13959 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13960 (scrolling_window): Check for overflow in size calculations.

13972 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13973 (get_doc_string): Check for size calculation overflow.
13974 Don't update size until allocation succeeds.
13975 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13976 EMACS_INT, where ptrdiff_t will do.
13977 (Fsubstitute_command_keys): Check for string overflow.
13979 * editfns.c (set_time_zone_rule): Don't assume environment length
13981 (message_length): Now ptrdiff_t, not int.
13982 (Fmessage_box): Don't update size until allocation succeeds.
13983 Don't assume message length fits in int.
13984 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13986 * emacs.c (main): Do not reallocate argv, since there is a null at
13987 the end that can be overwritten, and this way there's no need to
13988 worry about size-calculation overflow.
13989 (sort_args): Check for size-calculation overflow.
13991 * eval.c (init_eval_once, grow_specpdl): Don't update size until
13993 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
13995 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
13996 (x_set_scroll_bar_width, x_figure_window_size):
13997 Check for integer overflow.
13998 (x_set_alpha): Do not assume XINT fits in int.
14000 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14001 This is for the members text_lines, text_cols, total_lines, total_cols,
14002 where the system imposes an 'int' limit.
14004 * fringe.c (Fdefine_fringe_bitmap):
14005 Don't update size until alloc works.
14007 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14008 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14010 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14011 Check for size-calculation overflow.
14012 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14013 do, as we prefer signed integers.
14014 (id_to_widget.max_size, id_to_widget.used)
14015 (xg_store_widget_in_map, xg_remove_widget_from_map)
14016 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14017 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14018 Use and return ptrdiff_t, not int.
14019 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14020 * gtkutil.h: Change prototypes to match the above.
14022 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14023 are duplicate now that they've been promoted to lisp.h.
14024 (x_allocate_bitmap_record, x_alloc_image_color)
14025 (make_image_cache, cache_image, xpm_load):

14039 calculations. Don't update size until allocation succeeds.
14040 Redo calculations to avoid overflow.

14069 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14070 for command line length. Do not attempt to address one before the
14071 beginning of an array, as that's not portable.
14073 * term.c (max_frame_lines): Remove; unused.
14074 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14076 (encode_terminal_code, calculate_costs): Check for size
14077 calculation overflow.

14083 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14084 subtracting pointers.
14085 (gobble_line): Check for overflow more carefully. Don't update size
14088 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
14089 Don't update size until alloc done.

14099 Use ptrdiff_t, not int, for sizes.
14100 (Finternal_make_lisp_face, cache_face):
14101 Check for size calculation overflow.
14102 (cache_face): Treat size calculation overflows as if they were
14103 memory exhaustion (the usual treatment), rather than aborting.
14105 * xfns.c (x_encode_text, x_set_name_internal)
14106 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14107 sizes, since they can exceed INT_MAX in size. Check for size

14111 (xg_select): Check for size calculation overflow.
14112 Don't update size until alloc done.
14114 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14115 as sprintf is limited to int lengths.
14117 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14118 (X_LONG_MIN): New macros.
14119 Use them to make the following changes clearer.
14120 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14121 This change doesn't affect the value now, but it may help remind
14122 future maintainers not to raise the value too much later.
14123 (SELECTION_QUANTUM): Remove, replacing with ...
14124 (selection_quantum): ... new function, which avoids overflow.
14126 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14127 assumption that selection length fits in 'int'.

14140 (lisp_data_to_selection_data, x_property_data_to_lisp):

14144 Don't store size until memory allocation succeeds.
14145 (x_get_window_property): Plug memory leak on memory exhaustion.
14146 Don't double-block input; malloc is safe here. Don't assume 2**34
14147 - 4 fits in unsigned long. Add an xassert to check
14148 XGetWindowProperty overflow. Be more careful about overflow
14149 calculations, and distinguish size from memory overflow better.
14150 (receive_incremental_selection): When tracing, don't assume
14151 unsigned int is less than INT_MAX.
14152 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14153 harmful) conversions of unsigned short to int.
14154 (lisp_data_to_selection_data): Don't assume that integers
14155 in the range -65535 through -1 fit in an X unsigned short.
14156 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14157 result parameters unless successful. Rely on cons_to_unsigned
14158 to report problems with elements; the old code wasn't right anyway.
14159 (x_check_property_data): Check for int overflow; we cannot use
14160 a wider type due to X limits.
14161 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

14193 * lisp.h (hash_lookup, hash_put):
14194 * minibuf.c (Ftest_completion):
14195 Use ptrdiff_t for hash table indexes, not int (which is too
14196 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14197 32-bit --with-wide-int hosts).
14199 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14200 Add a FIXME comment about memory leaks.
14201 (syms_of_charset): Don't assume xmalloc returns.

14205 * character.h (CHAR_WIDTH):
14206 * indent.c (MULTIBYTE_BYTES_WIDTH):
14207 Use sanitize_char_width to avoid undefined and/or bad behavior
14208 with outlandish widths.
14209 * character.h (sanitize_tab_width): Rename from sanitize_width,
14210 now that we have two such functions. All uses changed.
14211 (sanitize_char_width): New inline function.
14213 Don't assume that tab-width fits in int.
14214 * character.h (sanitize_width): New inline function.

14231 exceed limits imposed by XClientMessageEvent, as well as the usual
14232 ptrdiff_t and size_t limits.
14234 * keyboard.c: Overflow, signedness and related fixes.
14235 (make_lispy_movement): Use same integer type in forward decl
14236 that is used in the definition.
14237 (read_key_sequence, keyremap_step):
14238 Change bufsize argument back to int, undoing my 2011-03-30 change.
14239 We prefer signed types, and int is wide enough here.
14240 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14241 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14242 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14243 length, not size_t. Use ptrdiff_t for index, not int.
14244 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14245 possibility of integer overflow.
14247 Overflow, signedness and related fixes for images.

14257 * xdisp.c (calc_pixel_width_or_height):
14258 * xfns.c (image_cache_refcount):
14259 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

14269 (lookup_image): Remove unnecessary tests.
14270 (xbm_image_p): Locals are now of int, not EMACS_INT,
14271 since parse_image_check makes sure they fit into int.
14272 (png_load, gif_load, svg_load_image):
14273 Prefer int to unsigned where either will do.
14274 (tiff_handler): New function, combining the cores of the
14275 old tiff_error_handler and tiff_warning_handler.
14276 This function is rewritten to use vsnprintf and thereby avoid
14277 stack buffer overflows. It uses only the features of vsnprintf
14278 that are common to both POSIX and native Microsoft.
14279 (tiff_error_handler, tiff_warning_handler): Use it.
14280 (tiff_load, gif_load, imagemagick_load_image):
14281 Don't assume :index value fits in 'int'.
14282 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14283 (imagemagick_load_image): Check that crop parameters fit into
14284 the integer types that MagickCropImage accepts. Don't assume
14285 Vimagemagick_render_type has a nonnegative value. Don't assume
14286 size_t fits in 'long'.
14287 (gs_load): Use printmax_t to print the widest integers possible.
14288 Check for integer overflow when computing image height and width.

14301 (handle_single_display_spec): If the display spec is of the form
14302 `(space ...)', and specifies display in the text area, return 2
14304 (try_cursor_movement): Check for the need to scroll more
14305 accurately, and prefer exact match for point under bidi.
14306 Don't advance `row' beyond the last row of the window.
14308 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
14309 into disp_prop; all users changed.

14327 positioning on the newline at EOL of R2L text within L2R
14328 paragraph, and vice versa.
14329 (try_cursor_movement): Check continued rows, in addition to
14330 continuation rows. Fixes unwarranted scroll when point enters a
14331 continued line of R2L text within an L2R paragraph, or vice versa.
14332 (cursor_row_p): Consider the case of point being equal to
14333 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14334 from the end of a short line to the beginning of a continued line
14335 of R2L text within L2R paragraph.

14359 * xdisp.c (redisplay_window): When computing centering_position,
14360 account for the height of the header line. (Bug#8874)
14362 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14363 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14364 candidate is selected by the mouse, and that candidate has a
14365 composed character under the mouse.
14367 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14368 coordinates reported by pos-visible-in-window-p for a composed
14369 character in column zero.

14378 consider it a hit if to_charpos is anywhere in the range of the
14379 composed buffer positions.
14381 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14383 * image.c (gif_load): Don't assume that each subimage has the same
14384 dimensions as the base image. Handle disposal method that is
14385 "undefined" by the gif spec (Bug#9335).
14387 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14389 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14394 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14395 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14396 from an Org mode buffer to a Speedbar frame.
14398 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14399 a composition, take its buffer position from IT->cmp_it.charpos.
14400 Fixes cursor positioning at the beginning of a line that begins
14401 with a composed character.
14403 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14405 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14406 character bidirectional type, use STRONG_L instead. Fixes crashes
14407 in a buffer produced by `describe-categories'.
14409 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14410 members before the level stack, so they would be saved and
14411 restored when copying iterator state. Fixes incorrect reordering
14412 around TABs covered by display properties.
14414 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

14548 the iterator structure wrt the object coming from a display
14549 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14550 properties. (Bug#9284)

14748 instead of hard-coded value of 2.
14749 (nsfont_draw): Call ns_draw_text_decoration instead.
14751 * nsterm.h: Add declaration for ns_draw_text_decoration.
14753 * nsterm.m (ns_draw_text_decoration): New function for drawing
14754 underline, overline, and strike-through.
14755 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14756 ns_draw_text_decoration. Change treatment of cursor drawing to
14757 accommodate underlining, etc.
14759 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14761 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14764 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14766 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14767 Without this fix, if a signal arrives just after memory fills up,
14768 'malloc' might be invoked reentrantly.
14770 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14771 In other words, assume that every image size is allowed, on non-X
14772 hosts. This assumption is probably wrong, but it lets Emacs compile.
14774 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14776 * regex.c (re_iswctype): Convert return values to boolean.
14778 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14780 * xdisp.c (compute_display_string_pos): Don't use cached display
14781 string position if the buffer had its restriction changed.
14784 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14786 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14788 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14790 Integer signedness and overflow and related fixes. (Bug#9079)
14792 * bidi.c: Integer size and overflow fixes.
14793 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14794 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14795 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14796 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14797 (bidi_find_other_level_edge):
14798 Use ptrdiff_t instead of EMACS_INT where either will do.
14799 This works better on 32-bit hosts configured --with-wide-int.
14800 (bidi_cache_ensure_space): Check for size-calculation overflow.
14801 Use % rather than repeated addition, for better worst-case speed.
14802 Don't set bidi_cache_size until after xrealloc returns, because it
14804 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14805 (bidi_cache_ensure_space): Also check that the bidi cache size
14806 does not exceed that of the largest Lisp string or buffer. See Eli
14807 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14809 * alloc.c (__malloc_size_t): Remove.
14810 All uses replaced by size_t. See Andreas Schwab's note
14811 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14813 * image.c: Improve checking for integer overflow.
14814 (check_image_size): Assume that f is nonnull, since
14815 it is always nonnull in practice. This is one less thing to
14816 worry about when checking for integer overflow later.
14817 (x_check_image_size): New function, which checks for integer
14818 overflow issues inside X.
14819 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14820 This removes the need for a memory_full check.
14821 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14822 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14823 (xbm_read_bitmap_data): Change locals back to 'int', since
14824 their values must fit in 'int'.
14825 (xpm_load_image, png_load, tiff_load):
14826 Invoke x_create_x_image_and_pixmap earlier,
14827 to avoid much needless work if the image is too large.
14828 (tiff_load): Treat overly large images as if
14829 x_create_x_image_and_pixmap failed, not as malloc failures.
14830 (gs_load): Use x_check_image_size.
14832 * gtkutil.c: Omit integer casts.
14833 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14834 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14836 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14838 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14839 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14840 would wrongly return t on a 64-bit host.
14842 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14843 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14844 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14845 and therefore cause GCC to emit a bogus diagnostic in some cases.
14847 * image.c: Integer signedness and overflow and related fixes.
14848 This is not an exhaustive set of fixes, but it's time to
14849 record what I've got.
14850 (lookup_pixel_color, check_image_size): Remove redundant decls.
14851 (check_image_size): Don't assume that arbitrary EMACS_INT values
14852 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14853 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14854 (tiff_load, imagemagick_load_image):
14855 Check for overflow in size calculations.
14856 (x_create_x_image_and_pixmap): Remove unnecessary test for
14857 xmalloc returning NULL; that can't happen.
14858 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14859 (xpm_color_bucket): Use better integer hashing function.
14860 (xpm_cache_color): Don't possibly over-allocate memory.
14861 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14862 (gif_memory_source):
14863 Use ptrdiff_t, not int or size_t, to record sizes.
14864 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14865 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14866 either works, as we prefer signed integers.
14867 (tiff_read_from_memory, tiff_write_from_memory):
14868 Return tsize_t, not size_t, since that's what the TIFF API wants.
14869 (tiff_read_from_memory): Don't fail simply because the read would
14870 go past EOF; instead, return a short read.
14871 (tiff_load): Omit no-longer-needed casts.
14872 (Fimagemagick_types): Don't assume size fits into 'int'.
14874 Improve hashing quality when configured --with-wide-int.
14875 * fns.c (hash_string): New function, taken from sxhash_string.
14876 Do not discard information about ASCII character case; this
14877 discarding is no longer needed.
14878 (sxhash-string): Use it. Change sig to match it. Caller changed.
14879 * lisp.h: Declare it.
14880 * lread.c (hash_string): Remove, since we now use fns.c's version.
14881 The fns.c version returns a wider integer if --with-wide-int is
14882 specified, so this should help the quality of the hashing a bit.
14884 * emacs.c: Integer overflow minor fix.
14885 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14886 Define only if GNU_LINUX.
14887 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14889 * dispnew.c: Integer signedness and overflow fixes.
14890 Remove unnecessary forward decls, that were a maintenance hassle.
14891 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14893 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14894 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14895 (prepare_desired_row, line_draw_cost):
14896 Use int, not unsigned, where either works.
14897 (save_current_matrix, restore_current_matrix):
14898 Use ptrdiff_t, not size_t, where either works.
14899 (init_display): Check for overflow more accurately, and without
14900 relying on undefined behavior.
14902 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14903 Remove, replacing with the new symbols in lisp.h. All uses changed.
14904 * fileio.c (make_temp_name):
14905 * filelock.c (lock_file_1, lock_file):
14906 * xdisp.c (message_dolog):
14907 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14908 Use pMd etc. instead.
14909 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14910 replacing the pWIDE etc. symbols removed from editfns.c.
14912 * keyboard.h (num_input_events): Now uintmax_t.
14913 This is (very slightly) less likely to mess up due to wraparound.
14916 * buffer.c: Integer signedness fixes.
14917 (alloc_buffer_text, enlarge_buffer_text):
14918 Use ptrdiff_t rather than size_t when either will do, as we prefer
14921 * alloc.c: Integer signedness and overflow fixes.
14922 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14923 (__malloc_size_t): Default to size_t, not to int.
14924 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14925 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14926 Prefer ptrdiff_t to size_t when either would do, as we prefer
14928 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14929 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14930 Now const. Initialize with values that are in range even if char
14932 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14933 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14934 These functions do the right thing with sizes > 2**32.
14935 (check_depth): Now ptrdiff_t, not int.
14936 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14937 Adjust to new way of storing sizes. Check for size overflow bugs
14939 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14940 slightly wrong anyway, as it missed one instance of
14941 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14942 (refill_memory_reserve): Omit needless cast to size_t.
14943 (mark_object_loop_halt): Mark as externally visible.
14945 * xselect.c: Integer signedness and overflow fixes.
14946 (Fx_register_dnd_atom, x_handle_dnd_message):
14947 Use ptrdiff_t, not size_t, since we prefer signed.
14948 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14949 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14950 x_dnd_atoms_size and x_dnd_atoms_length.
14952 * doprnt.c: Prefer signed to unsigned when either works.
14954 * doprnt.c (doprnt):
14956 * xdisp.c (vmessage):
14957 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14958 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14959 prefer signed arithmetic to avoid comparison confusion.
14960 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14961 but is a bit tricky.
14963 Assume freestanding C89 headers, string.h, stdlib.h.
14964 * data.c, doprnt.c, floatfns.c, print.c:
14965 Include float.h unconditionally.
14966 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14967 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14968 * regex.c: Likewise for stddef.h, string.h.
14969 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14970 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14971 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14972 (STDC_HEADERS): Remove obsolete defines.
14973 * sysdep.c: Include limits.h unconditionally.
14975 Assume support for memcmp, memcpy, memmove, memset.
14976 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14977 * regex.c (memcmp, memcpy):
14978 Remove; we assume C89 now.
14980 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14981 (__malloc_safe_bcopy): Remove; no longer needed.
14983 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14984 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14985 well either way, and we prefer signed to unsigned.
14987 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14989 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14990 closes the connection while we're reading (bug#9182).
14992 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14994 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14995 are specified (Bug#9168).
14997 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14999 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15000 Found by GCC static checking and --with-wide-int on a 32-bit host.
15002 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15004 * xdisp.c (compute_display_string_pos): Fix logic of caching
15005 previous display string position. Initialize cached_prev_pos to
15006 -1. Fixes slow-down at the beginning of a buffer.
15008 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15010 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15011 for attrs[LFACE_FONTSET_INDEX].
15013 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15015 * xml.c (parse_region): Remove unused local
15016 that was recently introduced.
15018 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15020 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15021 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15023 * xdisp.c (move_it_in_display_line_to): Record the best matching
15024 position for TO_CHARPOS while scanning the line, and restore it on
15025 exit if none of the characters scanned was an exact match.
15026 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15027 when exact match is impossible due to invisible text, and the
15028 lines are truncated.
15030 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15032 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15035 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15037 Fix a significant slow-down of cursor motion with C-n, C-p,
15038 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15039 auto-repeat under bidi redisplay in fontified buffers.
15040 * xdisp.c (compute_stop_pos_backwards): New function.
15041 (next_element_from_buffer): Call compute_stop_pos_backwards to
15042 find a suitable prev_stop when we find ourselves before
15044 (reseat): Don't look for prev_stop, as that could mean a very long
15046 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15047 <cached_disp_overlay_modiff>: Cache for last found display string
15049 (compute_display_string_pos): Return the cached position if asked
15050 about the same buffer in the same area of character positions, and
15051 the buffer wasn't changed since the time the display string
15052 position was cached.
15054 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15056 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15057 is an integer, which is important for empty lines. (Bug#9149)
15059 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15061 * frame.c (Fmodify_frame_parameters): In tty case, update the
15062 default face if necessary (Bug#4238).
15064 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15066 * editfns.c (Fstring_to_char): No need to explain what a character
15067 is in the docstring (Bug#6576).
15069 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15071 * xml.c (parse_region): Make sure we always return a tree.
15073 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15075 * xml.c (parse_region): If a document contains only comments,
15078 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15080 * xml.c (make_dom): Return comments, too.
15082 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15085 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15086 and the surrounding thread.
15087 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15088 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15089 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15091 * s/openbsd.h (BROKEN_SIGIO): Define.
15092 * unexelf.c (unexec) [__OpenBSD__]:
15093 Don't update the .mdebug section of the Alpha COFF symbol table.
15095 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15097 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15100 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15102 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15103 This fixes some race conditions on the permissions of any newly
15106 * alloc.c (valid_pointer_p): Use pipe, not open.
15107 This fixes some permissions issues when debugging.
15109 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15110 If fchown fails to set both uid and gid, try to set just gid,
15111 as that is sometimes allowed. Adjust the file's mode to eliminate
15112 setuid or setgid bits that are inappropriate if fchown fails.
15114 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15116 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15117 to compare Lisp_Objects.
15118 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15119 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15120 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15122 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15124 * lread.c (read_integer): Unread even EOF character.
15125 (read1): Likewise. Properly record start position of symbol.
15127 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15128 symbol character follows.
15130 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15132 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15133 This works around a problem with the previous change to Fcopy_file.
15134 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15135 and without this change, GCC might complain about discarding
15136 fchown's return value.
15138 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15140 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15142 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15144 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15146 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15148 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15149 it's used from the C level.
15151 * process.c: Use the same condition for POLL_FOR_INPUT in both
15152 keyboard.c and process.c (bug#1858).
15154 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15156 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15157 (Fgnutls_boot): Use it.
15159 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15161 * doc.c (Fsubstitute_command_keys): Revert last change.
15163 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15165 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15166 quotes the next character, and doesn't affect other longer
15167 sequences (bug#8935).
15169 * lread.c (syms_of_lread): Clarify that is isn't only
15170 `eval-buffer' and `eval-defun' that's affected by
15171 `lexical-binding' (bug#8460).
15173 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15175 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15176 bidi redisplay when a line includes both an image and is truncated.
15178 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15180 Fix minor problems found by static checking.
15181 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15182 (elsz): Now a signed constant, not a size_t var. We prefer signed
15183 types to unsigned, to avoid integer comparison confusion. Without
15184 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15185 "cannot optimize loop, the loop counter may overflow", a symptom
15187 * indent.c (Fvertical_motion): Mark locals as initialized.

15716 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15717 New macros, used in the buffer.c change.

15753 Random fixes. E.g., (random) never returned negative values.
15754 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15755 subseconds part to the entropy, as that's a bit more random.
15756 Prefer signed to unsigned, since the signedness doesn't matter and
15757 in general we prefer signed. When given a limit, use a
15758 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15759 latter isn't right if USE_2_TAGS_FOR_INTS.
15760 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15761 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15773 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15774 This is more efficient than Ffile_directory_p and avoids a minor race.

15778 * buffer.c (Foverlay_put): Say what the return value is
15781 * fileio.c (barf_or_query_if_file_exists): Check first if the file

15785 error be more correct.
15787 * fns.c (Frequire): Remove the mention of the .gz files, since

15801 Qgnutls_bootprop_verify_error (which is no longer used).
15803 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15804 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15805 Also (re)move comments that are misplaced or no longer relevant.
15807 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15809 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15834 * lread.c (syms_of_lread): Mention single symbols defined by

15906 * eval.c (struct backtrace): Simplify and port the data structure.
15907 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15908 signed bit field, as this assumption is not portable and it makes
15909 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15910 "char debug_on_exit : 1" as this is not portable either; instead,
15911 use the portable "unsigned int debug_on_exit : 1". Remove unused
15912 member evalargs. Remove obsolete comments about cc bombing out.
15914 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16066 * xfaces.c (syms_of_xfaces):
16067 * xfns.c (syms_of_xfns):
16068 * xmenu.c (syms_of_xmenu):
16069 * xsettings.c (syms_of_xsettings):
16070 * xterm.c (syms_of_xterm): Use DEFSYM.
16072 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
16074 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
16076 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16078 Integer and buffer overflow fixes (Bug#8873).
16080 * print.c (printchar, strout): Check for string overflow.
16081 (PRINTPREPARE, printchar, strout):
16082 Don't set size unless allocation succeeds.
16084 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16085 for sizes. Check for string overflow more accurately.
16086 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16088 * macros.c: Integer and buffer overflow fixes.
16089 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16090 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16091 Use ptrdiff_t, not int, for sizes.
16092 Don't increment bufsize until after realloc succeeds.
16093 Check for size-calculation overflow.
16094 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16096 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16098 * lread.c: Integer overflow fixes.
16099 (read_integer): Radix is now EMACS_INT, not int,
16100 to improve quality of diagnostics for out-of-range radices.
16101 Calculate buffer size correctly for out-of-range radices.
16102 (read1): Check for integer overflow in radices, and in
16103 read-circle numbers.
16104 (read_escape): Avoid int overflow.
16105 (Fload, openp, read_buffer_size, read1)
16106 (substitute_object_recurse, read_vector, read_list, map_obarray):
16107 Use ptrdiff_t, not int, for sizes.
16108 (read1): Use EMACS_INT, not int, for sizes.
16109 Check for size overflow.
16111 * image.c (cache_image): Check for size arithmetic overflow.
16113 * lread.c: Integer overflow issues.
16114 (saved_doc_string_size, saved_doc_string_length)
16115 (prev_saved_doc_string_size, prev_saved_doc_string_length):
16116 Now ptrdiff_t, not int.

16118 out-of-range doc string lengths.
16119 (read_list): Don't assume file position fits in int.
16120 (read_escape): Check for hex character overflow.
16122 2011-06-22 Leo Liu <sdl.web@gmail.com>
16124 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16125 Move to minibuffer.el.
16127 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16129 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16130 The following patches are for when GLYPH_DEBUG && !XASSERT.
16131 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16132 * dispnew.c (flush_stdout):
16133 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16134 Mark as externally visible.
16135 * dispnew.c (check_window_matrix_pointers): Now static.
16136 * dispnew.c (window_to_frame_vpos):
16137 * xfns.c (unwind_create_frame):
16138 * xterm.c (x_check_font): Remove unused local.
16139 * scroll.c (CHECK_BOUNDS):
16140 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16141 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16142 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16143 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16144 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16146 (debug_method_add): Use va_list and vsprintf rather than relying
16147 on undefined behavior with wrong number of arguments.
16148 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16149 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16150 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16151 since we're not interested in debugging glyphs with old libraries.
16152 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16153 GCC 4.6.0's static checking.
16155 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16157 Integer overflow and signedness fixes (Bug#8873).

16165 (x_create_bitmap_from_data, x_create_bitmap_from_file)
16166 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16167 (x_create_bitmap_from_xpm_data):
16168 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16169 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16171 * xfaces.c (load_pixmap):
16172 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16173 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16174 (.bitmaps_last, struct x_output.icon_bitmap):
16175 Use ptrdiff_t, not int, for bitmap indexes.
16176 (x_allocate_bitmap_record): Check for size overflow.
16177 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16179 Use ptrdiff_t, not int, for overlay counts.
16180 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16181 * editfns.c (overlays_around, get_pos_property):
16182 * textprop.c (get_char_property_and_overlay):
16183 * xdisp.c (next_overlay_change, note_mouse_highlight):
16184 * xfaces.c (face_at_buffer_position):
16185 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16186 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16187 (Fnext_overlay_change, Fprevious_overlay_change)
16188 (mouse_face_overlay_overlaps, Foverlays_in):
16189 Use ptrdiff_t, not int, for sizes.
16190 (overlays_at, overlays_in): Check for size-calculation overflow.
16192 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16194 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16195 (x_session_initialize): Do not assume string length fits in int.
16197 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16198 This is unlikely, but can occur if DPI is outlandish.
16200 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16201 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16203 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16204 * xrdb.c (magic_file_p, search_magic_path):
16205 Omit last arg SUFFIX; it was always 0. All callers changed.
16206 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16208 * xfont.c (xfont_match): Avoid need for strlen.
16210 * xfns.c: Don't assume strlen fits in int.
16211 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16213 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16214 not unsigned long, as we prefer signed integers. All callers changed.
16215 Detect integer overflow in repeat count.
16216 (message_dolog): Don't assume print length fits in 39 bytes.
16217 (display_mode_element): Don't assume strlen fits in int.
16219 * termcap.c: Don't assume sizes fit in int and never overflow.
16220 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16221 (gobble_line): Check for size-calculation overflow.
16223 * minibuf.c (Fread_buffer):
16224 * lread.c (intern, intern_c_string):
16225 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16226 Don't assume string length fits in int.
16228 * keyboard.c (parse_tool_bar_item):
16229 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16231 * font.c: Don't assume string length fits in int.
16232 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16233 Use ptrdiff_t, not int.
16234 (font_intern_prop): Don't assume string length fits in int.
16235 Don't assume integer property fits in fixnum.
16236 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16238 * filelock.c: Fix some buffer overrun and integer overflow issues.
16239 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16240 Reformulate so as not to need the command string.
16241 Invoke gzip -cd rather than gunzip, as it's more portable.
16242 (lock_info_type, lock_file_1, lock_file):
16243 Don't assume pid_t and time_t fit in unsigned long.
16244 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16245 (current_lock_owner): Prefer signed type for sizes.
16246 Use memcpy, not strncpy, where memcpy is what is really wanted.
16247 Don't assume (via atoi) that time_t and pid_t fit in int.
16248 Check for time_t and/or pid_t out of range, e.g., via a network share.
16249 Don't alloca where an auto var works fine.
16251 * fileio.c: Fix some integer overflow issues.
16252 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16253 Don't assume string length fits in int.
16254 (directory_file_name): Don't assume string length fits in long.
16255 (make_temp_name): Don't assume pid fits in int, or that its print
16256 length is less than 20.
16258 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16260 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16262 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16264 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16265 We prefer signed integers, even for size calculations.
16267 * emacs.c: Don't assume string length fits in 'int'.
16268 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16269 (main): Don't invoke strlen when not needed.
16271 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16272 (XD_DEBUG_MESSAGE): Don't waste a byte.
16274 * callproc.c (getenv_internal_1, getenv_internal)
16275 (Fgetenv_internal):
16276 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16278 * lread.c (invalid_syntax): Omit length argument.
16279 All uses changed. This doesn't fix a bug, but it simplifies the
16280 code away from its former Hollerith-constant appearance, and it's
16281 one less 'int' to worry about when looking at integer-overflow issues.
16282 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16284 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16285 This didn't break anything, but it didn't help either.
16286 It's confusing to put a bogus integer in a place where the actual
16287 value does not matter.
16288 (LIST_END_P): Remove unused macro and its bogus comment.
16289 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16291 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16292 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16294 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16295 We prefer signed types, and the value cannot exceed the EMACS_INT
16296 range anyway (because otherwise the length would not be representable).
16297 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16298 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16299 This avoids a GCC warning when WIDE_EMACS_INT.
16301 * indent.c (sane_tab_width): New function.
16302 (current_column, scan_for_column, Findent_to, position_indentation)
16303 (compute_motion): Use it. This is just for clarity.
16304 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16306 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16308 * lisp.h (lint_assume): New macro.
16309 * composite.c (composition_gstring_put_cache):
16310 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16312 * editfns.c, insdel.c:
16313 Omit unnecessary forward decls, to simplify future changes.
16315 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16317 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16319 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16320 Use much-faster test for byte-length change.
16321 Don't assume string byte-length fits in 'int'.
16322 Check that character arg fits in 'int'.
16323 (mapcar1): Declare byte as byte, for clarity.
16325 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16327 * fns.c (concat): Catch string overflow earlier.
16328 Do not rely on integer wraparound.
16330 * dispextern.h (struct it.overlay_strings_charpos)
16331 (struct it.selective): Now EMACS_INT, not int.
16332 * xdisp.c (forward_to_next_line_start)
16333 (back_to_previous_visible_line_start)
16334 (reseat_at_next_visible_line_start, next_element_from_buffer):
16335 Don't arbitrarily truncate the value of 'selective' to int.
16337 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16339 * composite.c: Don't truncate sizes to 'int'.
16340 (composition_gstring_p, composition_reseat_it)
16341 (composition_adjust_point): Use EMACS_INT, not int.
16342 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16343 not EMACS_UINT, for indexes.
16345 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16347 * buffer.c: Include <verify.h>.
16348 (struct sortvec.priority, struct sortstr.priority):
16349 Now EMACS_INT, not int.
16350 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16351 (struct sortstr.size, record_overlay_string)
16352 (struct sortstrlist.size, struct sortlist.used):
16353 Don't truncate size to int.
16354 (record_overlay_string): Check for size-calculation overflow.
16355 (init_buffer_once): Check at compile-time, not run-time.
16357 2011-06-22 Jim Meyering <meyering@redhat.com>
16359 Don't leak an XBM-image-sized buffer
16360 * image.c (xbm_load): Free the image buffer after using it.
16362 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16365 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16366 that Sun C diagnosed.
16367 * fns.c (secure_hash): Fix pointer signedness issue.
16368 * intervals.c (static_offset_intervals): New function.
16369 (offset_intervals): Use it.
16371 2011-06-21 Leo Liu <sdl.web@gmail.com>
16374 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16377 * fns.c (secure_hash): Rename from crypto_hash_function and change
16378 the first arg to accept symbols.
16379 (Fsecure_hash): New primitive.
16380 (syms_of_fns): New symbols.
16382 2011-06-20 Deniz Dogan <deniz@dogan.se>
16384 * process.c (Fset_process_buffer): Clarify return value in
16387 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16389 * dispnew.c (add_window_display_history): Use BVAR.
16391 * xdisp.c (debug_method_add): Use BVAR.
16392 (check_window_end, dump_glyph_matrix, dump_glyph)
16393 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16395 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16398 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16399 check till after the cache is created in init_frame_faces.
16401 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16403 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16405 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16407 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16408 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16409 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16411 Improve buffer-overflow checking (Bug#8873).
16412 * fileio.c (Finsert_file_contents):
16413 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16414 Remove the old (too-loose) buffer overflow checks.
16415 They weren't needed, since make_gap checks for buffer overflow.
16416 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16417 The old code merely checked for Emacs fixnum overflow, and relied
16418 on undefined (wraparound) behavior. The new code avoids undefined
16419 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16421 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16422 Tune. Don't use wider integers than needed. Don't use alloca.
16423 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16425 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16427 * insdel.c, lisp.h (buffer_overflow): New function.
16428 (insert_from_buffer_1, replace_range, replace_range_2):
16429 * insdel.c (make_gap_larger):
16430 * editfns.c (Finsert_char):
16431 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16433 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16435 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16437 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16439 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16440 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16442 * fileio.c: Don't assume EMACS_INT fits in off_t.
16443 (emacs_lseek): New static function.
16444 (Finsert_file_contents, Fwrite_region): Use it.
16445 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16447 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16449 * fns.c: Don't overflow int when computing a list length.
16450 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16451 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16452 truncation on 64-bit hosts. Check for QUIT every
16453 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16454 faster and is responsive enough.
16455 (Flength): Report an error instead of overflowing an integer.
16456 (Fsafe_length): Return a float if the value is not representable
16457 as a fixnum. This shouldn't happen except in contrived situations.
16458 (Fnthcdr, Fsort): Don't assume list length fits in int.
16459 (Fcopy_sequence): Don't assume vector length fits in int.
16461 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16462 (header_size, word_size): New constants.
16463 (allocate_vectorlike): Don't check size overflow here.
16464 (allocate_vector): Check it here instead, since this is the only
16465 caller of allocate_vectorlike that could cause overflow.
16466 Check that the new vector's length is representable as a fixnum.
16468 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16469 The previous code was bogus. For example, next_almost_prime (32)
16470 returned 39, which is undesirable as it is a multiple of 3; and
16471 next_almost_prime (24) returned 25, which is a multiple of 5 so
16472 why was the code bothering to check for multiples of 7?
16474 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16476 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16478 Variadic C functions now count arguments with ptrdiff_t.
16479 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16480 Back then I didn't know that the Emacs coding style prefers signed int.
16481 Also, in the meantime I found a few more instances where arguments
16482 were being counted with int, which may truncate counts on 64-bit
16483 machines, or EMACS_INT, which may be unnecessarily wide.
16484 * lisp.h (struct Lisp_Subr.function.aMANY)
16485 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16486 Arg counts are now ptrdiff_t, not size_t.
16487 All variadic functions and their callers changed accordingly.
16488 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16489 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16490 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16491 * callint.c (Fcall_interactively): Check arg count for overflow,
16492 to avoid potential buffer overrun. Use signed char, not 'int',
16493 for 'varies' array, so that we needn't bother to check its size
16494 calculation for overflow.
16495 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16496 * eval.c (apply_lambda):
16497 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16498 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16499 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16501 * callint.c (Fcall_interactively): Don't use index var as event count.
16503 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16504 * mem-limits.h (SIZE): Remove; no longer used.
16506 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16508 Remove unnecessary casts.
16509 * xterm.c (x_term_init):
16510 * xfns.c (x_set_border_pixel):
16511 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16512 These aren't needed now that we assume ANSI C.
16514 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16515 It's more likely to cause problems (due to unsigned overflow)
16518 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16520 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16522 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16524 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16526 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16528 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16530 GLYPH_CODE_FACE returns EMACS_INT, not int.
16531 * dispextern.h (merge_faces):
16532 * xfaces.c (merge_faces):
16533 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16534 Don't assume EMACS_INT fits in int.
16536 * character.h (CHAR_VALID_P): Remove unused parameter.
16537 * fontset.c, lisp.h, xdisp.c: All uses changed.
16539 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16541 * fns.c (concat): Minor tuning based on overflow analysis.
16542 This doesn't fix any bugs. Use int to hold character, instead
16543 of constantly refetching from Emacs object. Use XFASTINT, not
16544 XINT, for value known to be a character. Don't bother comparing
16545 a single byte to 0400, as it's always less.
16547 * floatfns.c (Fexpt):
16548 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16550 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16553 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16555 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16556 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16557 incorrectly succeed when S was a string, because 4294967386 was
16558 truncated before it was used.
16560 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16561 Otherwise, an out-of-range integer could cause undefined behavior
16564 * composite.c: Use int, not EMACS_INT, for characters.
16565 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16566 EMACS_INT, for values that are known to be in character range.
16567 This doesn't fix any bugs but is the usual style inside Emacs and
16568 may generate better code on 32-bit machines.
16570 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16571 This is for reasons similar to the recent CHAR_STRING fix.
16572 * charset.c (Fencode_char): Check that character arg is actually
16573 a character. Pass an int to ENCODE_CHAR.
16574 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16575 wider than 'int', as a compile-time check to prevent future regressions
16578 * character.c (char_string): Remove unnecessary casts.
16580 Make sure a 64-bit char is never passed to CHAR_STRING.
16581 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16582 by silently ignoring the top 32 bits, allowing some values
16583 that were far too large to be valid characters.
16584 * character.h: Include <verify.h>.
16585 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16586 arguments are no wider than unsigned, as a compile-time check
16587 to prevent future regressions in this area.
16589 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16590 (Fsubst_char_in_region):
16592 * xdisp.c (decode_mode_spec_coding):
16593 Adjust to CHAR_STRING's new requirement.
16594 * editfns.c (Finsert_char, Fsubst_char_in_region):
16595 * fns.c (concat): Check that character args are actually
16596 characters. Without this test, these functions did the wrong
16597 thing with wildly out-of-range values on 64-bit hosts.
16599 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16600 These casts should not be needed on 32-bit hosts, either.
16601 * keyboard.c (read_char):
16602 * lread.c (Fload): Remove casts to unsigned.
16604 * lisp.h (UNSIGNED_CMP): New macro.
16605 This fixes comparison bugs on 64-bit hosts.
16606 (ASCII_CHAR_P): Use it.
16607 * casefiddle.c (casify_object):
16608 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16609 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16610 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16611 * dispextern.h (FACE_FROM_ID):
16612 * keyboard.c (read_char): Use UNSIGNED_CMP.
16614 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16615 not to EMACS_INT, to avoid GCC warning.
16617 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16619 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16620 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16621 isn't needed on 32-bit machines.
16623 * buffer.c (Fgenerate_new_buffer_name):
16624 Use EMACS_INT for count, not int.
16625 (advance_to_char_boundary): Return EMACS_INT, not int.
16627 * data.c (Qcompiled_function): Now static.
16629 * window.c (window_body_lines): Now static.
16631 * image.c (gif_load): Rename local to avoid shadowing.
16633 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16634 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16635 * alloc.c (make_save_value): Integer argument is now of type
16636 ptrdiff_t, not int.
16637 (mark_object): Use ptrdiff_t, not int.
16638 * lisp.h (pD): New macro.
16639 * print.c (print_object): Use it.
16641 * alloc.c: Use EMACS_INT, not int, to count objects.
16642 (total_conses, total_markers, total_symbols, total_vector_size)
16643 (total_free_conses, total_free_markers, total_free_symbols)
16644 (total_free_floats, total_floats, total_free_intervals)
16645 (total_intervals, total_strings, total_free_strings):
16646 Now EMACS_INT, not int. All uses changed.
16647 (Fgarbage_collect): Compute overall total using a double, so that
16648 integer overflow is less likely to be a problem. Check for overflow
16649 when converting back to an integer.
16650 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16651 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16652 These were 'int' variables that could overflow on 64-bit hosts;
16653 they were never used, so remove them instead of repairing them.
16654 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16655 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16656 Previously, this ceilinged at INT_MAX, but that doesn't work on
16658 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16660 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16661 (allocate_vectorlike): Check for ptrdiff_t overflow.
16662 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16663 when a (possibly-narrower) signed value would do just as well.
16664 We prefer using signed arithmetic, to avoid comparison confusion.
16666 * alloc.c: Catch some string size overflows that we were missing.
16667 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16668 for convenience in STRING_BYTES_MAX.
16669 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16670 The definition here is exact; the one in lisp.h was approximate.
16671 (allocate_string_data): Check for string overflow. This catches
16672 some instances we weren't catching before. Also, it catches
16673 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16674 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16675 and ptrdiff_t and EMACS_INT are both 64 bits.
16677 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16678 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16679 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16681 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16683 * alloc.c (Fmake_string): Check for out-of-range init.
16685 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16687 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16689 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16691 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16692 xg_get_default_scrollbar_width.
16694 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16695 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16696 (style_changed_cb): Call update_theme_scrollbar_width and call
16697 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16698 all frames (Bug#8505).
16699 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16700 Call gtk_window_set_resizable if HAVE_GTK3.

16702 and height if HAVE_GTK3 (Bug#8505).
16703 (scroll_bar_width_for_theme): New variable.
16704 (update_theme_scrollbar_width): New function.
16705 (xg_get_default_scrollbar_width): Move code to
16706 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16707 (xg_initialize): Call update_theme_scrollbar_width.
16709 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16711 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16713 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16715 * frame.c (make_frame): Call other_buffer_safely instead of
16718 * window.c (temp_output_buffer_show): Call display_buffer with
16719 second argument Vtemp_buffer_show_specifiers and reset latter
16720 immediately after the call.
16721 (Vtemp_buffer_show_specifiers): New variable.
16722 (auto_window_vscroll_p, next_screen_context_lines)
16723 (Vscroll_preserve_screen_position): Remove leading asterisks from

16768 * window.c (delete_deletable_window): Re-add.
16769 (Fset_window_configuration): Rewrite to handle dead buffers and
16770 consequently deletable windows.
16771 (window_tree, Fwindow_tree): Remove. Supply functionality in
16773 (compare_window_configurations): Simplify code.

16906 Remove static from declaration of Qdelete_window, it's
16907 temporarily needed by Fbury_buffer.
16908 (replace_window): Don't assign orig_top_line and
16910 (Fdelete_window, delete_window): Remove. Window deletion is

16912 (window_loop): Remove DELETE_OTHER_WINDOWS case.
16913 Replace Fdelete_window calls with calls to Qdelete_window.
16914 (Fdelete_other_windows): Remove. Deleting other windows is

17320 Without this change, the gnutls library would invoke malloc etc.
17321 directly, which causes problems on non-SYNC_INPUT hosts, and which
17322 runs afoul of improving memory_full behavior. (Bug#8761)
17323 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17324 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17325 xfree instead of the default malloc, realloc, free.
17326 (Fgnutls_boot): No need to check for memory allocation failure,
17327 since xmalloc does that for us.

17356 need to be updated by these changes.
17357 * fns.c (make_hash_table, maybe_resize_hash_table):
17358 Check for integer overflow with large hash tables.
17359 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17360 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17361 (SXHASH_REDUCE): New macro.

17365 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17366 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17367 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17368 Rewrite to use FIXNUM_BITS, as this simplifies things.
17369 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17370 Adjust signatures to match updated version of code.
17371 (consing_since_gc): Now EMACS_INT, since a single hash table can
17372 use more than INT_MAX bytes.
17374 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17376 Make it possible to build with GCC-4.6+ -O2 -flto.
17378 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17380 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17382 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17383 Call minibuffer-inactive-mode.
17385 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17387 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17388 Update dependencies.
17390 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17392 * data.c (init_data): Remove code for UTS, this system is not
17395 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17397 Don't force ./temacs to start in terminal mode.
17399 * frame.c (make_initial_frame): Initialize faces in all cases, not
17400 only when CANNOT_DUMP is defined.
17401 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17403 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17405 * dispnew.c (add_window_display_history): Use const for the string
17406 pointer. Remove declaration, not needed.
17408 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17410 Use 'inline', not 'INLINE'.
17411 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17412 * alloc.c, fontset.c (INLINE): Remove.
17413 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17414 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17415 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17416 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17417 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17419 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17421 Make it possible to run ./temacs.
17423 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17424 syms_of_callproc does the same thing. Remove test for
17425 "initialized", do it in the caller.
17426 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17428 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17430 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17431 (read_minibuf): Use get_minibuffer.
17432 (syms_of_minibuf): Use DEFSYM.
17433 (Qmetadata): New var.
17434 * data.c (Qbuffer): Don't make it static.
17435 (syms_of_data): Use DEFSYM.
17437 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17439 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17440 (CCL_CODE_MIN): New macro.
17442 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17444 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17446 * eval.c (Qdebug): Now static.
17447 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17448 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17449 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17451 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17453 * image.c: Various fixes to ImageMagick code comments.
17454 (Fimagemagick_types): Doc fix.
17456 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17458 Minor fixes prompted by GCC 4.6.0 warnings.
17460 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17462 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17463 (x_clipboard_manager_save_all): Move extern decl to ...
17464 * xterm.h: ... here, so that it can be checked for consistency.
17466 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17468 * xselect.c (x_clipboard_manager_save_frame)
17469 (x_clipboard_manager_save_all): New functions.
17470 (Fx_clipboard_manager_save): Lisp function deleted.
17472 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17473 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17475 * xterm.h: Update prototype.
17477 2011-05-28 William Xu <william.xwl@gmail.com>
17479 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17480 exiting (Bug#8239).
17482 2011-05-28 Jim Meyering <meyering@redhat.com>
17484 Avoid a sign-extension bug in crypto_hash_function.
17485 * fns.c (to_uchar): Define.
17486 (crypto_hash_function): Use it to convert some newly-signed
17487 variables to unsigned, to avoid sign-extension bugs. For example,
17488 without this change, (md5 "truc") would evaluate to
17489 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17490 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17491 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17493 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17495 Integer overflow fixes.
17497 * dbusbind.c: Serial number integer overflow fixes.
17498 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17499 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17500 to hold a serial number that is too large for a fixnum.
17501 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17502 Check for serial numbers out of range. Decode any serial number
17503 that was so large that it became a float. (Bug#8722)
17505 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17506 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17507 Use XFASTINT rather than XUINT when numbers are nonnegative.
17508 (xd_append_arg, Fdbus_method_return_internal):
17509 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17510 arguments, check that Lisp number is nonnegative, rather than
17511 silently wrapping negative numbers around. (Bug#8722)
17512 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17515 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17517 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17519 ccl: Add integer overflow checks.
17520 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17521 (IN_INT_RANGE): New macros.
17522 (ccl_driver): Use them to check for integer overflow when
17523 decoding a CCL program. Many of the new checks are whether XINT (x)
17524 fits in int; it doesn't always, on 64-bit hosts. The new version
17525 doesn't catch all possible integer overflows, but it's an
17526 improvement. (Bug#8719)
17528 * alloc.c (make_event_array): Use XINT, not XUINT.
17529 There's no need for unsigned here.
17531 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17532 This follows up to the 2011-05-06 change that substituted uintptr_t
17533 for EMACS_INT. This case wasn't caught back then.
17535 Rework Fformat to avoid integer overflow issues.
17536 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17537 now (part of C89). Include <verify.h>.
17538 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17539 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17540 (Fformat): Avoid the prepass trying to compute sizes; it was only
17541 approximate and thus did not catch overflow reliably. Instead, walk
17542 through the format just once, formatting and computing sizes as we go,
17543 checking for integer overflow at every step, and allocating a larger
17544 buffer as needed. Keep track separately whether the format is
17545 multibyte. Keep only the most-recently calculated precision, rather
17546 than them all. Record whether each argument has been converted to
17547 string. Use EMACS_INT, not int, for byte and char and arg counts.
17548 Support field widths and precisions larger than INT_MAX. Avoid
17549 sprintf's undefined behavior with conversion specifications such as %#d
17550 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17551 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17552 formatting out-of-range floating point numbers with int
17553 formats. (Bug#8668)
17555 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17557 * data.c: Avoid integer truncation in expressions involving floats.
17558 * data.c: Include <intprops.h>.
17559 (arith_driver): When there's an integer overflow in an expression
17560 involving floating point, convert the integers to floating point
17561 so that the resulting value does not suffer from catastrophic
17562 integer truncation. For example, on a 64-bit host (* 4
17563 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17564 Do not rely on undefined behavior after integer overflow.
17566 merge count_size_as_multibyte, parse_str_to_multibyte
17567 * character.c, character.h (count_size_as_multibyte):
17568 Rename from parse_str_to_multibyte; all uses changed.
17569 Check for integer overflow.
17570 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17571 since it's now a duplicate of the other. This is more of
17572 a character than a buffer op, so better that it's in character.c.
17573 * fns.c, print.c: Adjust to above changes.
17575 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17577 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17579 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17581 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17582 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17583 (x_clipboard_manager_save): Now static.
17584 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17586 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17587 (crypto_hash_function): Now static.
17588 Fix pointer signedness problems. Avoid unnecessary initializations.
17590 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17592 * termhooks.h (Vselection_alist): Make it terminal-local.
17594 * terminal.c (create_terminal): Initialize it.
17596 * xselect.c: Support for clipboard managers.
17597 (Vselection_alist): Move to termhooks.h as terminal-local var.
17598 (LOCAL_SELECTION): New macro.
17599 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17600 (symbol_to_x_atom): Remove gratuitous arg.
17601 (x_handle_selection_request, lisp_data_to_selection_data)
17602 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17603 (x_own_selection, x_get_local_selection, x_convert_selection):
17604 New arg, specifying work frame. Use terminal-local Vselection_alist.
17605 (some_frame_on_display): Delete unused function.
17606 (Fx_own_selection_internal, Fx_get_selection_internal)
17607 (Fx_disown_selection_internal, Fx_selection_owner_p)
17608 (Fx_selection_exists_p): New optional frame arg.
17609 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17610 (x_handle_selection_clear): Don't treat other terminals with the
17611 same keyboard specially. Use the terminal-local Vselection_alist.
17612 (x_clear_frame_selections): Use Frun_hook_with_args.
17614 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17616 * xterm.h: Add support for those atoms.
17618 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17620 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17621 (converted_selections, conversion_fail_tag): New global variables.
17622 (x_selection_request_lisp_error): Free the above.
17623 (x_get_local_selection): Remove unnecessary code.
17624 (x_reply_selection_request): Args changed; handle arbitrary array
17625 of converted selections stored in converted_selections.
17626 Separate the XChangeProperty and SelectionNotify steps.
17627 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17628 (x_convert_selection): New function.
17629 (x_handle_selection_event): Simplify.
17630 (x_get_foreign_selection): Don't ignore incoming requests while
17631 waiting for an answer; this will fail when we implement
17632 SAVE_TARGETS, and seems unnecessary anyway.
17633 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17634 (Vx_sent_selection_functions): Doc fix.
17636 2011-05-26 Leo Liu <sdl.web@gmail.com>
17638 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17640 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17642 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17644 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17645 for fringe update if it has periodic bitmap.
17646 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17647 and fringe_bitmap_periodic_p.
17649 * fringe.c (get_fringe_bitmap_data): New function.
17650 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17651 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17652 row. Mark glyph row for fringe update if periodicity changed.
17654 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17655 for fringe update unless it has periodic bitmap.
17657 2011-05-25 Kenichi Handa <handa@m17n.org>
17659 * xdisp.c (get_next_display_element): Set correct it->face_id for
17660 a static composition.
17662 2011-05-24 Leo Liu <sdl.web@gmail.com>
17665 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17667 * fns.c (crypto_hash_function, Fsha1): New function.
17668 (Fmd5): Use crypto_hash_function.
17669 (syms_of_fns): Add Ssha1.
17671 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17673 * gnutls.c: Remove unused macros.
17674 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17675 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17676 Remove macros that are defined and never used.
17677 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17679 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17681 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17682 (Fx_get_selection_internal): Minor cleanup.
17683 (Fx_own_selection_internal): Rename arguments for consistency with
17686 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17688 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17690 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17692 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17694 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17696 * dispnew.c (scrolling_window): Don't exclude the case that the
17697 last enabled row in the desired matrix touches the bottom boundary.
17699 2011-05-21 Glenn Morris <rgm@gnu.org>
17701 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17702 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17703 and add some more files.
17705 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17707 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17708 report_file_error introduced by the change from 2011-05-07.
17710 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17712 * systime.h (Time): Define only if emacs is defined.
17713 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17714 where the include path doesn't have X11/X.h by default. See
17715 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17717 2011-05-20 Kenichi Handa <handa@m17n.org>
17719 * composite.c (find_automatic_composition): Fix previous change.
17721 2011-05-20 Glenn Morris <rgm@gnu.org>
17723 * lisp.mk: New file, split from Makefile.in.
17724 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17725 (shortlisp): Remove.
17726 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17728 2011-05-19 Glenn Morris <rgm@gnu.org>
17730 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17731 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17732 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17733 (lisp): Set the order to that of loadup.el.
17734 (shortlisp): Make it a copy of $lisp.
17735 (SOME_MACHINE_LISP): Remove.
17736 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17737 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17739 2011-05-18 Kenichi Handa <handa@m17n.org>
17741 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17742 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17743 (find_automatic_composition): Mostly rewrite for efficiency.
17745 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17747 * makefile.w32-in: Update dependencies.
17749 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17751 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17752 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17754 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17756 Fix some integer overflow issues, such as string length overflow.
17758 * insdel.c (count_size_as_multibyte): Check for string overflow.
17760 * character.c (lisp_string_width): Check for string overflow.
17761 Use EMACS_INT, not int, for string indexes and lengths; in
17762 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17763 the resulting string length overflows an EMACS_INT; instead,
17764 report a string overflow if no precision given. When checking for
17765 precision exhaustion, use a check that cannot possibly have
17766 integer overflow. (Bug#8675)
17767 * character.h (lisp_string_width): Adjust to new signature.
17769 * alloc.c (string_overflow): New function.
17770 (Fmake_string): Use it. This doesn't change behavior, but saves
17771 a few bytes and will simplify future changes.
17772 * character.c (string_escape_byte8): Likewise.
17773 * lisp.h (string_overflow): New decl.
17775 Fixups, following up to the user-interface timestamp change.
17776 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17777 for UI timestamps, instead of unsigned long.
17778 * msdos.c (mouse_get_pos): Likewise.
17779 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17780 * w32gui.h (Time): Define by including "systime.h" rather than by
17781 declaring it ourselves. (Bug#8664)
17783 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17784 * image.c (clear_image_cache): Likewise.
17786 * term.c (term_mouse_position): Don't assume time_t wraparound.
17788 Be more systematic about user-interface timestamps.
17789 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17790 and sometimes 'EMACS_UINT', to represent these timestamps.
17791 This change causes it to use 'Time' uniformly, as that's what X uses.
17792 This makes the code easier to follow, and makes it easier to catch
17793 integer overflow bugs such as Bug#8664.
17794 * frame.c (Fmouse_position, Fmouse_pixel_position):
17795 Use Time, not unsigned long, for user-interface timestamps.
17796 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17797 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17798 * keyboard.h (last_event_timestamp): Likewise.
17799 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17800 * menu.h (xmenu_show): Likewise.
17801 * term.c (term_mouse_position): Likewise.
17802 * termhooks.h (struct input_event.timestamp): Likewise.
17803 (struct terminal.mouse_position_hook): Likewise.
17804 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17805 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17806 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17807 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17808 what it was before.
17809 * menu.h, termhooks.h: Include "systime.h", for Time.
17811 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17812 Don't assume that the difference between two unsigned long values
17813 can fit into an integer. At this point, we know button_down_time
17814 <= event->timestamp, so the difference must be nonnegative, so
17815 there's no need to cast the result if double-click-time is
17816 nonnegative, as it should be; check that it's nonnegative, just in
17817 case. This bug is triggered when events are more than 2**31 ms
17818 apart (about 25 days). (Bug#8664)
17820 * xselect.c (last_event_timestamp): Remove duplicate decl.
17821 (x_own_selection): Remove needless cast to unsigned long.
17823 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17824 that always fit in int. Use a sentinel instead of a counter, to
17825 avoid a temp and to allay GCC's concerns about possible int overflow.
17826 * frame.h (struct frame): Use int for menu_bar_items_used
17827 instead of EMACS_INT, since it always fits in int.
17829 * menu.c (grow_menu_items): Check for int overflow.
17831 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17833 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17834 Before, the code was not consistent. These values cannot exceed
17835 2**31 - 1 so there's no need to make them unsigned.
17836 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17837 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17838 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17840 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17842 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17843 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17844 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17845 presumably because the widths might not match.
17847 * window.c (size_window): Avoid needless test at loop start.
17849 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17851 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17853 2011-05-12 Drew Adams <drew.adams@oracle.com>
17855 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17857 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17859 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17860 `width' to `bar_area_x' and `bar_area_width', respectively.
17861 (x_scroll_run): Take account of fringe background extension.
17863 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17864 Rename local vars `left' and `width' to `bar_area_x' and
17865 `bar_area_width', respectively.
17866 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17867 background extension.
17869 2011-05-10 Jim Meyering <meyering@redhat.com>
17871 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17873 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17875 * image.c (Finit_image_library): Return t for built-in image types,
17876 like pbm and xbm. (Bug#8640)
17878 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17880 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17882 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17884 * w32console.c (Fset_screen_color): Doc fix.
17885 (Fget_screen_color): New function.
17886 (syms_of_ntterm): Defsubr it.
17888 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17889 unlink the temporary file if Fcall_process didn't create it in the
17891 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17892 child process will be redirected to a file specified with `:file'.
17893 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17894 cue to call_process_cleanup not to close that handle.
17896 2011-05-07 Ben Key <bkey76@gmail.com>
17898 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17899 one of two shell specific rules, either bootstrap-temacs-CMD or
17900 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17901 to the previous implementation of the bootstrap-temacs rule.
17902 The bootstrap-temacs-CMD rule is similar to the previous
17903 implementation of the bootstrap-temacs rule except that it
17904 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17907 These changes, along with some changes to nt/configure.bat,
17908 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17909 earlier fix to add support for --cflags and --ldflags options
17910 that include quotes so that it works whether make uses cmd or
17913 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17915 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17916 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17918 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17919 a string. Handle both cases.
17920 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17921 (Fdbus_register_method): Use Qinvalid_function.
17923 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17925 * makefile.w32-in: Update dependencies.
17926 (LISP_H): Add inttypes.h and stdin.h.
17927 (PROCESS_H): Add unistd.h.
17929 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17931 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17932 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17934 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17936 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17938 * term.c (vfatal): Remove stray call to va_end.
17939 It's not needed and the C Standard doesn't allow it here anyway.
17941 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17942 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17944 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17947 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17949 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17951 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17953 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17955 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17957 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17958 * charset.c (Fdefine_charset_internal): Don't initialize
17959 charset.code_space[15]. The value was garbage, on hosts with
17960 32-bit int (Bug#8600).
17962 * lread.c (read_integer): Be more consistent with string-to-number.
17963 Use string_to_number to do the actual conversion; this avoids
17964 rounding errors and fixes some other screwups. Without this fix,
17965 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17966 (digit_to_number): Move earlier, for benefit of read_integer.
17967 Return -1 if the digit is out of range for the base, -2 if it is
17968 not a digit in any supported base. (Bug#8602)
17970 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17972 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17973 to match comment at start of function. This also removes a
17974 GCC warning about overflow in a 32+64-bit port.
17976 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17978 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17979 Reported by Stefan Monnier in
17980 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17981 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17982 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17984 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17985 (EMACS_UINTPTR): Likewise, with uintptr_t.
17987 * lisp.h: Prefer 64-bit EMACS_INT if available.
17988 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17989 on 32-bit hosts that have 64-bit int, so that they can access
17991 However, temporarily disable this change unless the temporary
17992 symbol WIDE_EMACS_INT is defined.
17994 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17996 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17997 This removes an assumption that EMACS_INT and long are the same
17998 width as pointers. The assumption is true for Emacs porting targets
17999 now, but we want to make other targets possible.
18000 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18001 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18002 In the rest of the code, change types of integers that hold casted
18003 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18004 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18005 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18006 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18007 No need to cast type when ORing.
18008 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18009 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18010 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18011 assume EMACS_INT is the same width as char *.
18012 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18013 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18014 Remove no-longer-needed casts.
18015 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18016 (xg_tool_bar_help_callback, xg_make_tool_item):
18017 Use EMACS_INTPTR to hold an integer
18018 that will be cast to void *; this can avoid a GCC warning
18019 if EMACS_INT is not the same width as void *.
18020 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18021 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18022 (current_message_1, set_message_1):
18023 Use a local to convert to proper width without a cast.
18024 * xmenu.c (dialog_selection_callback): Likewise.
18026 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18027 Also, don't assume VALBITS / RAND_BITS is less than 5,
18028 and don't rely on undefined behavior when shifting a 1 left into
18030 * lisp.h (get_random): Change signature to match.
18032 * lread.c (hash_string): Use size_t, not int, for hash computation.
18033 Normally we prefer signed values; but hashing is special, because
18034 it's better to use unsigned division on hash table sizes so that
18035 the remainder is nonnegative. Also, size_t is the natural width
18036 for hashing into memory. The previous code used 'int', which doesn't
18037 retain enough info to hash well into very large tables.
18038 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18040 * dbusbind.c: Don't possibly lose pointer info when converting.
18041 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18042 Use XPNTR rather than XHASH, so that the high-order bits of
18043 the pointer aren't lost when converting through void *.
18045 * eval.c (Fautoload): Don't double-shift a pointer.
18047 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18049 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18051 * gnutls.c (DEF_GNUTLS_FN):
18052 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18054 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18056 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18059 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18061 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18062 New version that can reserve upto 2GB of heap space.
18064 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18066 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18068 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18070 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18071 `gnutls_certificate_set_x509_key_file'.
18073 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18075 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18076 Update dependencies.
18078 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18080 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18081 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18082 Remove unused parameter `fildes'.
18083 * process.c (read_process_output, send_process): Don't pass it.
18085 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18087 Fix previous change: the library cache is defined in w32.c.
18088 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18089 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18091 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18093 Implement dynamic loading of GnuTLS on Windows.
18095 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18096 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18097 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18100 * gnutls.c (Qgnutls_dll): Define.
18101 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18102 (gnutls_*): Declare function pointers.
18103 (init_gnutls_functions): New function to initialize function pointers.
18104 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18105 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18106 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18107 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18108 (emacs_gnutls_write, emacs_gnutls_read)
18109 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18110 (Fgnutls_available_p): New function.
18111 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18112 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18113 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18115 * image.c: Include w32.h.
18116 (Vimage_type_cache): Delete.
18117 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18118 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18119 (w32_delayed_load): Move to w32.c.
18121 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18123 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18124 (w32_delayed_load): Move from image.c. When loading a library, record
18125 its filename in the :loaded-from property of the library id.
18126 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18127 Initialize and staticpro them.
18128 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18130 * process.c: Include lisp.h before w32.h, not after.
18131 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18132 instead of gnutls_record_check_pending.
18134 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18136 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18138 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18139 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18142 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18144 * xterm.c (x_set_frame_alpha): Do not set property on anything
18145 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18147 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18149 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18151 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18153 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
18154 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

18160 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
18161 (Qgnutls_bootprop_callbacks_verify): Make static.
18163 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18165 * callproc.c: Indentation fixup.
18167 * sysdep.c (wait_for_termination_1): Make static.
18168 (wait_for_termination, interruptible_wait_for_termination):
18169 Move after wait_for_termination_1.
18171 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18173 * sysdep.c (interruptible_wait_for_termination): New function
18174 which is like wait_for_termination, but allows keyboard
18177 * callproc.c (Fcall_process): Add (:file "file") as an option for
18179 (Fcall_process_region): Ditto.
18181 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18183 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18184 rather than `XVECTOR (FOO)->size'.
18186 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18187 inttypes.h, as a gnulib replacement is used if it not available in
18190 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18192 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18193 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18194 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18196 * coding.c (coding_alloc_by_realloc): Error out if destination
18197 will grow beyond MOST_POSITIVE_FIXNUM.
18198 (decode_coding_emacs_mule): Abort if there isn't enough place in
18199 charbuf for the composition carryover bytes. Reserve an extra
18200 space for up to 2 characters produced in a loop.
18201 (decode_coding_iso_2022): Abort if there isn't enough place in
18202 charbuf for the composition carryover bytes.
18204 2011-04-21 Eli Zaretskii <eliz@gnu.org>

18207 aborting when %lld or %lll format is passed.
18208 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18209 %llo or %llx format is passed. (Bug#8545)
18211 * window.c (window_scroll_line_based): Use a marker instead of
18212 simple variables to record original value of point. (Bug#7952)
18214 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18215 produced by %s or %c overflows available buffer space. (Bug#8545)
18217 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18219 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18220 (SIZE_MAX): Move defn after all includes, as they might #define it.
18222 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18224 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18226 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

18229 (command_loop_1): Run `delayed-warnings-hook'
18230 if Vdelayed_warnings_list is non-nil.
18231 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18232 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18234 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18236 * doprnt.c (doprnt): Don't return value smaller than the buffer
18237 size if the message was truncated. (Bug#8545).
18239 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18241 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18242 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18244 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18246 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18248 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18250 * makefile.w32-in: Update dependencies.
18252 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18254 Improve `doprnt' and its usage. (Bug#8545)
18255 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18256 `format_end'. Remove support for %l as a conversion specifier.
18257 Don't use xrealloc. Improve diagnostics when the %l size modifier
18258 is used. Update the commentary.
18260 * eval.c (verror): Simplify calculation of size_t.
18262 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18265 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18267 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18270 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18272 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18273 This makes this file independent of the recent pseudovector change.
18275 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18277 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18279 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18280 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18281 Remove unused local.
18282 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18284 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18285 GCC 4.6.0 optimizes based on type-based alias analysis.
18286 For example, if b is of type struct buffer * and v of type struct
18287 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18288 != &v->size, and therefore "v->size = 1; b->size = 2; return
18289 v->size;" must therefore return 1. This assumption is incorrect
18290 for Emacs, since it type-puns struct Lisp_Vector * with many other
18291 types. To fix this problem, this patch adds a new type struct
18292 vectorlike_header that documents the constraints on layout of vectors
18293 and pseudovectors, and helps optimizing compilers not get fooled
18294 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18295 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18296 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18298 (XSETPVECTYPE): Rewrite in terms of new macro.
18299 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18300 This is a bit clearer, and further avoids the possibility of
18301 undesirable aliasing.
18302 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18303 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18304 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18305 since Lisp_Subr is a special case (no "next" field).
18306 (ASIZE): Now uses header.size rather than size.
18307 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18308 to avoid the hassle of writing XVECTOR (foo)->header.size.
18309 (struct vectorlike_header): New type.
18310 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18311 object, to help avoid aliasing.
18312 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18313 (SUBRP): Likewise, since Lisp_Subr is a special case.
18314 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18315 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18316 (struct Lisp_Hash_Table): Combine first two members into a single
18317 struct vectorlike_header member. All uses of "size" and "next" members
18318 changed to be "header.size" and "header.next".
18319 * buffer.h (struct buffer): Likewise.
18320 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18321 * frame.h (struct frame): Likewise.
18322 * process.h (struct Lisp_Process): Likewise.
18323 * termhooks.h (struct terminal): Likewise.
18324 * window.c (struct save_window_data, struct saved_window): Likewise.
18325 * window.h (struct window): Likewise.
18326 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18327 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18328 * buffer.c (init_buffer_once): Likewise.
18329 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18331 * process.c (Fformat_network_address): Use local var for size,
18334 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18336 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18337 * data.c (atof): Remove decl; no longer used or needed.
18338 (digit_to_number): Move to lread.c.
18339 (Fstring_to_number): Use new string_to_number function, to be
18340 consistent with how the Lisp reader treats infinities and NaNs.
18341 Do not assume that floating-point numbers represent EMACS_INT
18342 without losing information; this is not true on most 64-bit hosts.
18343 Avoid double-rounding errors, by insisting on integers when
18344 parsing non-base-10 numbers, as the documentation specifies.
18345 * lisp.h (string_to_number): New decl, replacing ...
18346 (isfloat_string): Remove.
18347 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18348 (read1): Do not accept +. and -. as integers; this
18349 appears to have been a coding error. Similarly, do not accept
18350 strings like +-1e0 as floating point numbers. Do not report
18351 overflow for integer overflows unless the base is not 10 which
18352 means we have no simple and reliable way to continue.
18353 Break out the floating-point parsing into a new
18354 function string_to_number, so that Fstring_to_number parses
18355 floating point numbers consistently with the Lisp reader.
18356 (digit_to_number): Move here from data.c. Make it static inline.
18357 (E_CHAR, EXP_INT): Remove, replacing with ...
18358 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18359 (string_to_number): New function, replacing isfloat_string.
18360 This function checks for valid syntax and produces the resulting
18361 Lisp float number too. Rework it so that string-to-number
18362 no longer mishandles examples like "1.0e+". Use strtoumax,
18363 so that overflow for non-base-10 numbers is reported only when
18364 there's no portable and simple way to convert to floating point.
18366 * textprop.c (set_text_properties_1): Rewrite for clarity,
18367 and to avoid GCC warning about integer overflow.
18369 * intervals.h (struct interval): Use EMACS_INT for members
18370 where EMACS_UINT might cause problems. See
18371 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18372 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18373 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18375 (offset_intervals): Tell GCC not to worry about length overflow
18376 when negating a negative length.
18378 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18379 (overrun_check_free): Likewise.
18381 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18382 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18385 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18386 (gnutls_make_error): Rename local to avoid shadowing.
18387 (gnutls_emacs_global_deinit): ifdef out; not used.
18388 (Fgnutls_boot): Use const for pointer to readonly storage.
18389 Comment out unused local. Fix pointer signedness problems.
18391 * lread.c (openp): Don't stuff size_t into an 'int'.
18392 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18393 about possible signed overflow.
18395 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18396 (GDK_KEY_g): Don't define if already defined.
18397 (xg_prepare_tooltip): Avoid pointer signedness problem.
18398 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18400 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18401 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18403 * xfns.c (Fx_window_property): Simplify a bit,
18404 to make a bit faster and to avoid GCC 4.6.0 warning.
18405 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18407 * fns.c (internal_equal): Don't assume size_t fits in int.
18409 * alloc.c (compact_small_strings): Tighten assertion a little.
18411 Replace pEd with more-general pI, and fix some printf arg casts.
18412 * lisp.h (pI): New macro, generalizing old pEd macro to other
18413 conversion specifiers. For example, use "...%"pI"d..." rather
18414 than "...%"pEd"...".
18415 (pEd): Remove. All uses replaced with similar uses of pI.
18416 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18417 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18418 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18419 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18420 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18421 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18422 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18424 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18425 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18426 * print.c (safe_debug_print, print_object): Likewise.
18427 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18429 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18430 avoiding the 0 flag, which is not portable.
18431 * process.c (Fmake_network_process): Use pI to avoid cast.
18432 * region-cache.c (pp_cache): Likewise.
18433 * xdisp.c (decode_mode_spec): Likewise.
18434 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18435 behavior on 64-bit hosts with printf arg.
18436 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18437 (x_stop_queuing_selection_requests): Likewise.
18438 (x_get_window_property): Don't truncate byte count to an 'int'
18441 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18442 here, since it parses constructs like leading '-' and spaces,
18443 which are not wanted; and it overflows with large numbers.
18444 Instead, simply match F[0-9]+, which is what is wanted anyway.
18446 * alloc.c: Remove unportable assumptions about struct layout.
18447 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18448 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18449 (allocate_vectorlike, make_pure_vector): Use the new macros,
18450 plus offsetof, to remove unportable assumptions about struct layout.
18451 These assumptions hold on all porting targets that I know of, but
18452 they are not guaranteed, they're easy to remove, and removing them
18453 makes further changes easier.
18455 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18456 This doesn't fix a bug but makes the code clearer.
18457 (string_overrun_cookie): Now const. Use initializers that
18458 don't formally overflow signed char, to avoid warnings.
18459 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18460 can cause Emacs to crash when string overrun checking is enabled.
18461 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18462 multiple of sizeof (EMACS_INT); it need not be, if
18463 alignof(EMACS_INT) < sizeof (EMACS_INT).
18464 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18466 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
18468 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
18470 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18472 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18473 supposed to be handshaking. (Bug#8556)
18474 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18476 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18478 * lisp.h (Qdebug): List symbol.
18479 * eval.c (Qdebug): Restore global linkage.
18480 * keyboard.c (debug-on-event): New variable.
18481 (handle_user_signal): Break into debugger when debug-on-event
18482 matches the current signal symbol.
18484 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18486 * alloc.c (check_sblock, check_string_bytes)
18487 (check_string_free_list): Convert to standard C.
18489 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18491 * w32.c (emacs_gnutls_push): Fix typo.
18493 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18495 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18496 "cast to pointer from integer of different size".
18498 Improve doprnt and its use in verror. (Bug#8545)
18499 * doprnt.c (doprnt): Document the set of format control sequences
18500 supported by the function. Use SAFE_ALLOCA instead of always
18503 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18504 is one byte too soon. Don't use xrealloc; instead xfree and
18507 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18509 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18512 * gnutls.c: Renamed global_initialized to
18513 gnutls_global_initialized. Added internals for the
18514 :verify-hostname-error, :verify-error, and :verify-flags
18515 parameters of `gnutls-boot' and documented those parameters in the
18516 docstring. Start callback support.
18517 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18518 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18519 on error. Return error code.
18520 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18521 (emacs_gnutls_read): Likewise.
18522 (Fgnutls_boot): Return handshake error code.
18523 (emacs_gnutls_handle_error): New function.
18524 (wsaerror_to_errno): Likewise.

18535 buffered some data internally if no FDs are set for TLS
18538 * makefile.w32-in (OBJ2): Add gnutls.$(O).

18586 <char-direction-table>: Deleted.
18588 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18590 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
18591 * doprnt.c: Include limits.h.
18592 (SIZE_MAX): New macro.
18593 (doprnt): Return a size_t value. 2nd arg is now size_t.
18594 Many local variables are now size_t instead of int or unsigned.
18595 Improve overflow protection. Support `l' modifier for integer
18596 conversions. Support %l conversion. Don't assume an EMACS_INT
18597 argument for integer conversions and for %c.
18599 * lisp.h (doprnt): Restore prototype.
18601 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18602 $(SRC)/character.h.
18604 * Makefile.in (base_obj): Add back doprnt.o.
18606 * deps.mk (doprnt.o): Add back prerequisites.
18607 (callint.o): Depend on character.h.
18609 * eval.c (internal_lisp_condition_case): Include the handler
18610 representation in the error message.
18611 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
18612 when breaking from the loop.
18614 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
18616 * callint.c (Fcall_interactively): When displaying error message
18617 about invalid control letter, pass the character's codepoint, not
18618 a pointer to its multibyte form. Improve display of the character
18619 in octal and display also its hex code.
18621 * character.c (char_string): Use %x to display the (unsigned)
18622 codepoint of an invalid character, to avoid displaying a bogus
18625 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18626 `error', not SYMBOL_NAME itself.
18628 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18629 character arguments to `error'.
18631 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18632 to `error' in error message about FINAL_CHAR argument. Make sure
18633 FINAL_CHAR is a character, and use %c when it is passed as
18634 argument to `error'.
18636 2011-04-23 Eli Zaretskii <eliz@gnu.org>

18698 Define only if needed.
18700 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18701 by pacifying GCC about it. Maybe it's time to retire it?

18704 * dispextern.h (struct redisplay_interface): Rename param

18753 compatible char. Avoid the old compiler warnings about
18754 out-of-range initializers by using, for example, '\xab' rather
18757 * xgselect.c (xgselect_initialize): Check vs interface
18758 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

18823 * nsfont.m: Fixed bugs in ns_get_family and
18824 ns_descriptor_to_entity that were caused by using free to
18825 deallocate memory blocks that were allocated by xmalloc (via
18826 xstrdup). This caused Emacs to crash when compiled with
18827 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18828 --enable-checking=xmallocoverrun). xfree is now used to
18829 deallocate these memory blocks.

18843 (emacs_read, emacs_write): Remove check for negative size, as the
18844 Emacs source code has been audited now.
18845 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
18846 (emacs_read, emacs_write): Use it.
18847 * process.c (send_process): Adjust to the new signatures of
18848 emacs_write and emacs_gnutls_write. Do not attempt to store
18849 a byte offset into an 'int'; it might overflow.
18850 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

19180 * buffer.c (buffer_count): Remove unused var.
19182 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

19184 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
19185 * dispextern.h (bidi_dump_cached_states): Remove, since it's
19186 exported only to the debugger.
19188 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
19189 * atimer.h (run_all_atimers): Remove; not exported.
19191 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19192 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19193 was inaccessible from Lisp.
19194 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19195 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19197 alloc.c: Import and export fewer symbols, and remove unused items.
19198 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19200 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19201 it's not optimized away by whole-program optimization.

19214 (mark_backtrace): Define only if BYTE_MARK_STACK.
19215 * xdisp.c (message_enable_multibyte): Now static.
19217 Declare Lisp_Object Q* variables to be 'static' if not exported.
19218 This makes it easier for human readers (and static analyzers)
19219 to see whether these variables are used from other modules.
19220 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

19231 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19233 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19235 Make Emacs functions such as Fatom 'static' by default.
19236 This makes it easier for human readers (and static analyzers)
19237 to see whether these functions can be called from other modules.
19238 DEFUN now defines a static function. To make the function external
19239 so that it can be used in other C modules, use the new macro DEFUE.

19245 Remove decls, since these functions are now static.
19246 (Funintern, Fget_internal_run_time): New decls, since these functions
19247 were already external.

19257 Mark functions with DEFUE instead of DEFUN,
19258 if they are used in other modules.

19260 decls for now-static functions.
19261 * buffer.h (Fdelete_overlay): Remove decl.

19297 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19299 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19300 when at ZV. (Bug#8487)
19302 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>

19310 * xsettings.c (read_and_apply_settings): Likewise.
19312 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19313 (overrun_check_free): Protoize.
19315 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19317 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19318 since callers should never pass a negative size.
19319 Change the signature to match that of plain 'read' and 'write'; see
19320 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19321 * lisp.h: Update prototypes of emacs_write and emacs_read.
19323 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19325 * xdisp.c (redisplay_window): Don't try to determine the character
19326 position of the scroll margin if the window start point w->startp
19327 is outside the buffer's accessible region. (Bug#8468)
19329 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19331 Fix write-region and its subroutines for buffers > 2GB.
19332 * fileio.c (a_write, e_write): Modify declaration of arguments and
19333 local variables to support buffers larger than 2GB.
19334 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19336 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19337 argument, local variables, and return value.
19339 * lisp.h: Update prototypes of emacs_write and emacs_read.
19341 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19343 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19345 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19347 Fix more problems found by GCC 4.6.0's static checks.
19349 * xdisp.c (vmessage): Use a better test for character truncation.
19351 * charset.c (load_charset_map): <, not <=, for optimization,
19352 and to avoid potential problems with integer overflow.
19353 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19354 * casetab.c (set_identity, shuffle): Likewise.
19355 * editfns.c (Fformat): Likewise.
19356 * syntax.c (skip_chars): Likewise.
19358 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19359 This also lets GCC 4.6.0 generate slightly better loop code.
19361 * callint.c (Fcall_interactively): <, not <=, for optimization.
19362 (Fcall_interactively): Count the number of arguments produced,
19363 not the number of arguments given. This is simpler and lets GCC
19364 4.6.0 generate slightly better code.
19366 * ftfont.c: Distingish more carefully between FcChar8 and char.
19367 The previous code passed unsigned char * to a functions like
19368 strlen and xstrcasecmp that expect char *, which does not
19369 conform to the C standard.
19370 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19371 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19372 char * when the C standard requires it.
19374 * keyboard.c (read_char): Remove unused var.
19376 * eval.c: Port to Windows vsnprintf (Bug#8435).
19377 Include <limits.h>.
19378 (SIZE_MAX): Define if the headers do not.
19379 (verror): Do not give up if vsnprintf returns a negative count.
19380 Instead, grow the buffer. This ports to Windows vsnprintf, which
19381 does not conform to C99. Problem reported by Eli Zaretskii.
19382 Also, simplify the allocation scheme, by avoiding the need for
19383 calling realloc, and removing the ALLOCATED variable.
19385 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19387 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19388 But keep the doprint source code for now, as we might revamp it
19389 and use it again (Bug#8435).
19390 * lisp.h (doprnt): Remove.
19391 * Makefile.in (base_obj): Remove doprnt.o.
19392 * deps.mk (doprnt.o): Remove.
19394 error: Print 32- and 64-bit integers portably (Bug#8435).
19395 Without this change, on typical 64-bit hosts error ("...%d...", N)
19396 was used to print both 32- and 64-bit integers N, which relied on
19397 undefined behavior.
19398 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19399 * lisp.h (error, verror): Mark as printf-like functions.
19400 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19401 Report overflow in size calculations when allocating printf buffer.
19402 Do not truncate output string at its first null byte.
19403 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19404 Truncate the output at a character boundary, since vsnprintf does not
19406 * charset.c (check_iso_charset_parameter): Convert internal
19407 character to string before calling 'error', since %c now has the
19409 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19410 overflow when computing char to be passed to 'error'. Do not
19411 pass Lisp_Object to 'error'; pass the integer instead.
19412 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19413 formatted with plain %d.
19415 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19417 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19419 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19421 * xterm.c (x_catch_errors): Remove duplicate declaration.
19423 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19425 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19427 2011-04-10 Jim Meyering <meyering@redhat.com>
19429 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19430 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19431 return ssize_t not "int", and use size_t as the buffer length.
19432 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19433 * gnutls.h: Update declarations.
19434 * process.c (read_process_output): Use ssize_t, to match.
19435 (send_process): Likewise.
19437 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19439 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19441 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19443 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19444 Use unsigned char, to match FcChar8 type definition.
19446 * xterm.c (handle_one_xevent):
19447 * xmenu.c (create_and_show_popup_menu):
19448 * xselect.c (x_decline_selection_request)
19449 (x_reply_selection_request): Avoid type-punned deref of X events.
19451 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19453 Fix some uses of `int' instead of EMACS_INT.
19454 * search.c (string_match_1, fast_string_match)
19455 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19456 (scan_buffer, find_next_newline_no_quit)
19457 (find_before_next_newline, search_command, Freplace_match)
19458 (Fmatch_data): Make some `int' variables be EMACS_INT.
19460 * xdisp.c (display_count_lines): 3rd argument and return value now
19461 EMACS_INT. All callers changed.
19462 (pint2hrstr): Last argument is now EMACS_INT.
19464 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19465 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19466 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19477 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19478 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19480 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19481 (encode_invocation_designation): Last argument P_NCHARS is now
19483 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19484 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19486 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19489 * ccl.c (Fccl_execute_on_string): Declare some variables
19492 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19494 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19496 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19498 * process.c (Fformat_network_address): Doc fix.
19500 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19502 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19504 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19506 * keyboard.c (read_char): Call Lisp function help-form-show,
19507 instead of using internal_with_output_to_temp_buffer.
19508 (Qhelp_form_show): New var.
19509 (syms_of_keyboard): Use DEFSYM macro.
19511 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19518 (list_processes_1): Delete.
19520 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19522 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19524 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19526 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19528 Fix more problems found by GCC 4.6.0's static checks.
19530 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

19534 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19536 * xdisp.c (vmessage): Mark as a printf-like function.
19538 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19540 * sound.c (sound_warning): Don't crash if arg contains a printf format.

19549 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19550 This avoids several warnings with gcc -Wstrict-overflow.
19551 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19552 directly, rather than having caller test rule sign. This avoids
19553 some unnecessary tests.
19554 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19555 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19556 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19558 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19559 (xfont_open): Avoid unnecessary tests.
19561 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19563 * composite.h, composite.c (composition_gstring_put_cache):
19564 Use EMACS_INT, not int, for length.
19566 * composite.h (COMPOSITION_DECODE_REFS): New macro,
19567 breaking out part of COMPOSITION_DECODE_RULE.
19568 (COMPOSITION_DECODE_RULE): Use it.
19569 * composite.c (get_composition_id): Remove unused local vars,
19570 by using the new macro.
19572 * textprop.c (set_text_properties_1): Change while to do-while,
19573 since the condition is always true at first.
19575 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19576 (interval_deletion_adjustment): Return unsigned value.
19579 * process.c (list_processes_1, create_pty, read_process_output):
19580 (exec_sentinel): Remove vars that were set but not used.
19581 (create_pty): Remove unnecessary "volatile"s.
19582 (Fnetwork_interface_info): Avoid possibility of int overflow.
19583 (read_process_output): Do adaptive read buffering even if carryover.
19584 (read_process_output): Simplify nbytes computation if buffered.

19592 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19593 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19595 * print.c (print_error_message): Avoid int overflow.
19597 * font.c (font_list_entities): Redo for clarity,
19598 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19600 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19601 (font_score): Avoid potential overflow in diff calculation.

19604 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19606 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19608 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19609 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19610 can always succeed if overflow has undefined behavior.
19612 * search.c (boyer_moore, wordify): Remove vars set but not used.
19613 (wordify): Omit three unnecessary tests.
19615 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19616 All callers changed. This avoids the need for an unused var.
19618 * casefiddle.c (casify_region): Remove var that is set but not used.
19620 * dired.c (file_name_completion): Remove var that is set but not used.
19622 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19624 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19625 (Finsert_file_contents): Remove unnecessary code checking fd.
19627 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19628 Check for integer overflow on size calculations.
19630 * buffer.c (Fprevious_overlay_change): Remove var that is set
19633 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19634 Remove vars that are set but not used.
19635 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19636 (timer_check_2): Mark vars as initialized.
19638 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19640 * image.c (lookup_image): Remove var that is set but not used.
19641 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19643 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19644 that are set but not used.
19646 * xfns.c (make_invisible_cursor): Don't return garbage
19647 if XCreateBitmapFromData fails (Bug#8410).
19649 * xselect.c (x_get_local_selection, x_handle_property_notify):
19650 Remove vars that are set but not used.
19652 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19653 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19655 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19656 Remove var that is set but not used.
19657 (scroll_bar_windows_size): Now size_t, not int.
19658 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19659 Check for overflow.
19661 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19662 (map_tty_color) [!defined MSDOS]: Likewise.
19664 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19666 * coding.c: Remove vars that are set but not used.
19667 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19668 All callers changed.
19669 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19670 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19671 (decode_coding_charset): Remove vars that are set but not used.
19673 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19674 that is set but not used.
19676 * print.c (print_object): Remove var that is set but not used.
19678 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19679 The gnulib version avoids calling malloc in the usual case,
19680 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19681 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19682 * filelock.c (current_lock_owner): Likewise.
19683 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19684 * sysdep.c: Include allocator.h, careadlinkat.h.
19685 (emacs_no_realloc_allocator): New static constant.
19686 (emacs_readlink): New function.
19687 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19688 ../lib/careadlinkat.h.
19690 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19692 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19693 first non-nil return value).
19695 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
19697 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
19698 if not defined (Bug#8403).
19700 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19702 * xdisp.c (display_count_lines): Remove parameter `start',
19703 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19704 (get_char_face_and_encoding): Remove parameter `multibyte_p',
19705 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19707 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19708 and thereabouts. All callers changed.
19709 (get_per_char_metric): Remove parameter `f', unused since
19710 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19712 2011-04-02 Jim Meyering <meyering@redhat.com>
19714 do not dereference NULL upon failed strdup
19715 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19716 (ns_get_family): Likewise.
19718 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19720 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19722 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19724 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19727 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19729 Add lexical binding.
19731 * window.c (Ftemp_output_buffer_show): New fun.
19732 (Fsave_window_excursion):
19733 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19735 * lread.c (lisp_file_lexically_bound_p): New function.
19736 (Fload): Bind Qlexical_binding.
19737 (readevalloop): Remove `evalfun' arg.
19738 Bind Qinternal_interpreter_environment.
19739 (Feval_buffer): Bind Qlexical_binding.
19740 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19742 (syms_of_lread): Declare `lexical-binding'.
19744 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19746 * keyboard.c (eval_dyn): New fun.
19747 (menu_item_eval_property): Use it.
19749 * image.c (parse_image_spec): Use Ffunctionp.
19751 * fns.c (concat, mapcar1): Accept byte-code-functions.
19753 * eval.c (Fsetq): Handle lexical vars.
19754 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19755 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19756 (FletX, Flet): Obey lexical binding.
19757 (Fcommandp): Handle closures.
19758 (Feval): New `lexical' arg.
19759 (eval_sub): New function extracted from Feval. Use it almost
19760 everywhere where Feval was used. Look up vars in lexical env.
19762 (Ffunctionp): Move from subr.el.
19763 (Ffuncall): Handle closures.
19764 (apply_lambda): Remove `eval_flags'.
19765 (funcall_lambda): Handle closures and new byte-code-functions.
19766 (Fspecial_variable_p): New function.
19767 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19768 but without exporting it to Lisp.
19770 * doc.c (Fdocumentation, store_function_docstring):
19771 * data.c (Finteractive_form): Handle closures.
19773 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19776 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19778 (exec_byte_code): New function extracted from Fbyte_code to handle new
19779 calling convention for byte-code-functions. Add new byte-codes.
19781 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19783 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19785 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19787 * xdisp.c (redisplay_internal): Fix prototype.
19789 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19791 * xdisp.c (SCROLL_LIMIT): New macro.
19792 (try_scrolling): Use it when setting scroll_limit.
19793 Limit scrolling to 100 screen lines.
19794 (redisplay_window): Even when falling back on "recentering",
19795 position point in the window according to scroll-conservatively,
19796 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19798 (try_scrolling): When point is above the window, allow searching
19799 as far as scroll_max, or one screenful, to compute vertical
19800 distance from PT to the scroll margin position. This prevents
19801 try_scrolling from unnecessarily failing when
19802 scroll-conservatively is set to a value slightly larger than the
19803 window height. Clean up the case of PT below the margin at bottom
19804 of window: scroll_max can no longer be INT_MAX. When aggressive
19805 scrolling is in use, don't let point enter the opposite scroll
19806 margin as result of the scroll.
19807 (syms_of_xdisp) <scroll-conservatively>: Document the
19808 threshold of 100 lines for never-recentering scrolling.
19810 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

19815 (message_log_check_duplicate): Remove parameters `prev_bol' and
19816 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19817 (redisplay_internal): Remove parameter `preserve_echo_area',
19818 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19820 * indent.c (Fvertical_motion):
19821 * window.c (window_scroll_pixel_based, Frecenter):
19822 Don't pass `need_y_p' to `move_it_by_lines'.
19824 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19826 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19827 steal a few bits to be more compact.
19828 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19829 Remove unneeded casts.
19831 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19833 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19835 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19836 binding" message (bug#7967).
19838 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19840 Fix more problems found by GCC 4.6.0's static checks.
19842 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19843 Remove unused local var.
19845 * editfns.c (Fmessage_box): Remove unused local var.
19847 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19848 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19849 Omit unused local vars.
19850 * window.c (shrink_windows): Omit unused local var.
19851 * menu.c (digest_single_submenu): Omit unused local var.
19852 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19853 Omit unused local var.
19855 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19856 Don't assume string length fits in int.
19857 (keyremap_step, read_key_sequence): Use size_t for sizes.
19858 (read_key_sequence): Don't check last_real_key_start redundantly.
19860 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19861 instead of alloca (Bug#8344).
19863 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19864 (Fbacktrace_frame): Don't assume nframes fits in int.
19866 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

19871 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19873 * cm.c (calccost): Turn while-do into do-while, for clarity.
19875 * keyboard.c (syms_of_keyboard): Use the same style as later
19876 in this function when indexing through an array. This also
19877 works around GCC bug 48267.
19879 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19881 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19883 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19884 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19886 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19887 This avoids undefined behavior on integer overflow, and is a bit
19888 more convenient anyway since it is compared to a size_t variable.
19890 Variadic C functions now count arguments with size_t, not int.
19891 This avoids an unnecessary limitation on 64-bit machines, which
19892 caused (substring ...) to crash on large vectors (Bug#8344).
19893 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19894 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

19902 * fns.c (concat): Likewise.
19903 * frame.c (x_set_frame_parameters): Likewise.
19904 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19905 0 if not found, not -1. All callers changed.
19907 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19908 (stack_copy_size): Now size_t, not int.
19909 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19911 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19913 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19914 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19915 All callers changed.
19917 * lisp.h (multibyte_char_to_unibyte):
19918 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19919 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19930 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19931 don't set the hook to nil, but remove the offending function instead.
19932 (Qcommand_hook_internal): Remove, unused.
19933 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19934 Vcommand_hook_internal.
19936 * eval.c (enum run_hooks_condition): Remove.
19937 (funcall_nil, funcall_not): New functions.
19938 (run_hook_with_args): Call each function through a `funcall' argument.

19952 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19953 All callers changed.
19955 * w32.c (_wsa_errlist): Use braces for struct initializers.
19957 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

20115 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20117 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20118 unconditionally since it does the check itself.
20120 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20122 Fix more problems found by GCC 4.5.2's static checks.
20124 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20125 the first time through the loop, since we know p0 < p1 then.
20126 This also avoids a gcc -Wstrict-overflow warning.
20128 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20129 leading to a memory leak, possible in functions like
20130 load_charset_map_from_file that can allocate an unbounded number
20131 of objects (Bug#8318).
20133 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20134 that could (at least in theory) be that large.
20136 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20137 This is less likely to overflow, and avoids undefined behavior if
20138 overflow does occur. All callers changed. Use strtoul to scan
20139 for the unsigned long integer.
20140 (pint2hrstr): Simplify and tune code slightly.
20141 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20151 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20154 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20156 * process.c (Fmake_network_process): Use socklen_t, not int,
20157 where POSIX says socklen_t is required in portable programs.
20158 This fixes a porting bug on hosts like 64-bit HP-UX, where
20159 socklen_t is wider than int (Bug#8277).
20160 (Fmake_network_process, server_accept_connection):
20161 (wait_reading_process_output, read_process_output):
20164 * process.c: Rename or move locals to avoid shadowing.

20174 Make tparam.h and terminfo.c consistent.
20175 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20176 Include tparam.h instead, since it declares them.
20177 * cm.h (PC): Remove extern decl; tparam.h now does this.
20178 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20179 * terminfo.c: Include tparam.h, to check interfaces.
20180 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20181 (tparam): Adjust signature to match interface in tparam.h;
20182 this removes some undefined behavior. Check that outstring and len
20183 are zero, which they always are with Emacs.
20184 * tparam.h (PC, BC, UP): New extern decls.
20186 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20187 (xftfont_open): Rename locals to avoid shadowing.
20189 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

20204 (find_automatic_composition, composition_adjust_point): Likewise.
20205 (composition_update_it): Mark var as initialized.
20206 (find_automatic_composition): Mark vars as initialized,
20207 with a FIXME (Bug#8290).

20211 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20212 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20213 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20214 to avoid shadowing.
20216 * textprop.c (property_change_between_p): Remove; unused.
20218 * intervals.c (interval_start_pos): Now static.
20220 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20226 Fix pointer signedness.
20227 (alsa_choose_format): Remove unused local var.
20228 (wav_play): Initialize a variable to 0, to prevent undefined
20229 behavior (Bug#8278).
20231 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20233 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20235 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20236 clobbering (Bug#8298).
20237 * sysdep.c (sys_subshell): Likewise.
20238 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20240 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20241 This should get cleaned up, so that child_setup has the
20242 same signature on all platforms.
20244 * callproc.c (call_process_cleanup): Now static.
20245 (relocate_fd): Rename locals to avoid shadowing.
20247 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20249 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20250 not to be necessary, and produces flickering.
20252 2011-03-20 Glenn Morris <rgm@gnu.org>
20254 * config.in: Remove file.
20256 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20258 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20259 are now in src/globals.h.

20286 (sigchld_handler): Now static.
20288 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20289 That way, the code declares only the vars that it needs.

20300 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20301 Define only if needed.
20303 * unexelf.c (unexec): Name an expression,
20304 to avoid gcc -Wbad-function-cast warning.
20305 Use a different way to cause a compilation error if anyone uses
20306 n rather than nn, a way that does not involve shadowing.
20307 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20309 * deps.mk (unexalpha.o): Remove; unused.
20311 New file unexec.h, the (simple) interface for unexec (Bug#8267).

20382 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20385 * lisp.h (eassert): Check that the argument compiles, even if
20386 ENABLE_CHECKING is not defined.
20388 * data.c (Findirect_variable): Name an expression, to avoid
20389 gcc -Wbad-function-cast warning.

20406 (Fmemory_limit): Cast sbrk's returned value to char *.

20432 (RETALLOC_IF): Define only if needed.
20433 (WORDCHAR_P): Likewise. This one is never needed, but is used
20434 only in a comment talking about a compiler bug, so put inside
20435 the #if 0 of that comment.

20465 gcpro1, gcpro2, etc.
20466 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20468 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

20473 Rename locals to avoid shadowing.
20475 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

20479 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...

20484 (downcase, upcase1): New static inline functions.
20485 (DOWNCASE, UPCASE1): Reimplement using these functions.
20486 This avoids undefined behavior in expressions like

20520 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

20527 * buffer.c (fix_overlays_before): Mark locals as initialized.
20528 (fix_start_end_in_overlays): Likewise. This function should be
20529 simplified by using pointers-to-pointers, but that's a different

20538 to suppress a gcc -Wclobbered warning that does not seem to be right.
20539 (MAXPATHLEN): Define only if needed.
20541 * process.c (serial_open, serial_configure): Move decls from here ...
20542 * systty.h: ... to here, so that they can be checked.

20888 a block, when the outer 'i' will do.

20901 -Wuninitialized does not deduce are never used uninitialized.
20902 (detect_coding_iso_2022): Initialize a local variable that might
20903 be used uninitialized. Leave a FIXME because it's not clear that
