8 * fileio.c (Finsert_file_contents): Doc fix.
10 * w32proc.c (new_child, delete_child, find_child_pid): For a
11 subprocess, consider its slot being in use as long as its process
12 handle (procinfo.hProcess) is not NULL. This avoids reusing the
13 slot when a new process is started immediately after killing
14 another one, without waiting enough time for the first process to
15 be reaped and resources allocated for it be orderly freed.
17 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
19 2012-12-21 Chong Yidong <cyd@gnu.org>
21 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).

25 2012-12-21 Eli Zaretskii <eliz@gnu.org>
27 * w32.c (get_name_and_id): Always pass NULL as the first argument
28 of lookup_account_sid. Avoids crashes with UNC file names that
29 refer to DFS domains, not to specific machine names. (Bug#12621)
30 Remove now unused argument FNAME; all callers changed.
31 (get_file_owner_and_group): Remove now unused argument FNAME; all
34 2012-12-21 Chong Yidong <cyd@gnu.org>
36 * editfns.c (Finsert_char): Since read-char-by-name now signals an
37 error for invalid chars, don't check for a nil return value.
39 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
41 Avoid calls to CHAR_TO_BYTE if byte position is known.

70 * intervals.c (graft_intervals_info_buffer): Find an interval here.
72 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
74 * coding.c (Fdetect_coding_region): Do not check start and end with
75 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
76 (code_convert_region): Likewise.
78 2012-12-18 Eli Zaretskii <eliz@gnu.org>
80 * w32.c (acl_get_file, acl_set_file): Run the file name through

125 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
127 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
128 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
129 for some of that bug's symptoms can now cause Emacs to abort.
130 Remove the workaround.
131 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
132 The bug that caused SIGCHLD to get lost has been fixed, and the

135 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
137 * sysdep.c (emacs_abort): Bump backtrace size to 40.

161 (record_infile, record_pending_deletion): New prototypes.
163 * w32proc.c (new_child): Initialize input_file and
164 pending_deletion members of the child.
165 (delete_child): Delete the child's temporary input file, if any,
166 that is pending deletion.

177 * callproc.c (Fcall_process): Don't overwrite infile with result
179 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
180 asynchronous subprocess, record the name of the input file name,
182 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
183 delete the file, record it as pending deletion when the subprocess
186 2012-12-14 Eli Zaretskii <eliz@gnu.org>
188 * editfns.c [HAVE_PWD_H]: Include grp.h.
190 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

194 Fix permissions bugs with setgid directories etc. (Bug#13125)
195 * dired.c (Ffile_attributes): Return t as the 9th attribute,
196 to mark it as a placeholder. The old value was often wrong.

198 file-ownership-preserved-p instead, with its new group arg.
199 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

208 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
209 try to get accurate owner and group information from NT file
210 security APIs. This is to make most callers of 'stat' and
211 'lstat', which don't need that information, much faster.
213 * dired.c (Ffile_attributes) [WINDOWSNT]:
214 Set w32_stat_get_owner_group to a non-zero value, to request accurate
215 owner and group information from 'lstat'.

219 * fileio.c (Finsert_file_contents): Don't put tail into head area,
220 as that confuses set-auto-coding, so insist on the head-read
221 returning the full 1024 bytes. Let lseek compute the tail offset;

249 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
251 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
252 fstat shouldn't fail, and if it does fail copy-file should not proceed.
253 Remove unnecessary S_ISLNK test, as (contra the comments) this
254 function can't copy symlinks. Improve quality of error message
255 when attempting to copy files that are neither regular files nor
258 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>

266 2012-12-12 Daniel Colascione <dancol@dancol.org>
268 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
269 the dumped Emacs is not a sparse file, greatly improving Cygwin

275 incoming inotify event.
277 2012-12-11 Eli Zaretskii <eliz@gnu.org>
279 * xdisp.c (handle_face_prop): Fix logic of computing
280 it->start_of_box_run_p.
281 (append_space_for_newline): If the glyph row is R2L, reset the
282 iterator's end_of_box_run_p flag before prepending the space glyph.
283 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
284 iterator's start_of_box_run_p flag before prepending the stretch.
285 (append_glyph, produce_image_glyph, append_composite_glyph)
286 (append_stretch_glyph, append_glyphless_glyph): Reverse the
287 left_box_line_p and right_box_line_p flags of the glyph for R2L
288 glyph rows. (Bug#13011)

300 2012-12-11 Eli Zaretskii <eliz@gnu.org>
302 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
303 encoded_file_name, which is what it is.

338 (hinst): Remove unneeded extern declaration.
339 (_start): Remove initialization of above variables; remove
340 initialization of hinst, as cache_system_info now does that.
342 * emacs.c (main): Call cache_system_info early in startup; we
343 previously weren't calling it in Cygwin builds.

505 (syms_of_editfns): Don't initialize initial_tz;
506 init_editfns now does it.
507 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
508 * lisp.h (xputenv): New decl.
510 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
512 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
514 2012-12-08 Eli Zaretskii <eliz@gnu.org>
516 * w32.c (unsetenv, sys_putenv): New functions.
518 2012-12-08 Chong Yidong <cyd@gnu.org>
520 * editfns.c (Finsert_char): Make the error message more
521 informative (Bug#12992).
523 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
525 Simplify get_lim_data.
526 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
527 Remove USG and vlimit methods; no longer used these days.
528 Add #error catchall just in case.
530 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
531 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
532 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
533 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
534 (deleted_pid_list, Fdelete_process, create_process)
535 (record_child_status_change, handle_child_signal, deliver_child_signal)
536 (init_process_emacs, syms_of_process):
537 Assume SIGCHLD is defined.
538 (parse_signal): Remove. All uses removed.
539 (abbr_to_signal): New static function.
540 (Fsignal_process): Use it to convert signal names to ints.
541 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
542 kill (getpgrp (), ...).
543 (emacs_sigaction_init): Assume SIGCHLD is defined.
544 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
545 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
546 * syssignal.h (EMACS_KILLPG): Remove.
547 All uses replaced by 'kill' with a negative pid.
548 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
549 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
551 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
553 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
554 This will cause a production Emacs to dump core instead of
557 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
559 * frame.c (make_frame): Do not set window's buffer to t.
560 * window.c (Fsplit_window_internal): Likewise. Previously it was
561 used to indicate that the window is being set up. Now we use
562 set_window_buffer for all new windows, so the condition in ...
563 (Fset_window_buffer): ... is always true and can be removed.
565 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
567 Convenient macro to check whether the buffer is hidden.
568 * buffer.h (BUFFER_HIDDEN_P): New macro.
569 * frame.c (make_frame): Use it. Adjust comment.
570 * buffer.c (candidate_buffer): New function.
571 (Fother_buffer, other_buffer_safely): Use it.
573 2012-12-06 Eli Zaretskii <eliz@gnu.org>
575 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
576 if the child process is still running. Instead, exit the wait
577 loop and return zero. (Bug#13086)
579 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
581 * frame.h (x_char_width, x_char_height): Remove prototypes.

590 (command_loop_2, top_level_1): Add static to match prototype.
592 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
594 Fix a recently-introduced delete-process race condition.
595 * callproc.c, process.h (record_kill_process):
596 New function, containing part of the old call_process_kill.
597 (call_process_kill): Use it.
598 This does not change call_process_kill's behavior.
599 * process.c (Fdelete_process): Use record_kill_process to fix a
600 race condition that could cause Emacs to lose track of a child.
602 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
604 Avoid code duplication between prev_frame and next_frame.
605 * frame.c (candidate_frame): New function. Add comment.
606 (prev_frame, next_frame): Use it. Adjust comment.
608 2012-12-06 Eli Zaretskii <eliz@gnu.org>
610 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
611 fails, signal an error instead of continuing with an empty
613 Encode expanded temp file pattern before passing it to mkstemp or
616 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
617 Encode the file name before passing it to dostounix_filename, in
618 case it will downcase it (under w32-downcase-file-names).
621 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
623 Minor call-process cleanups.
624 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
625 at the same time as other platforms, to simplify analysis.
626 No need for fd0_volatile since we have synch_process_fd.
627 Avoid needless emacs_close; arg is always negative.
629 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
631 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
634 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
636 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
637 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
638 and mouse_face_hidden members to a bitfields.
639 * frame.h (struct frame): Remove set-but-not-used space_width member.
640 (FRAME_SPACE_WIDTH): Remove.
641 * nsterm.m, w32term.c, xterm.c: Adjust users.
642 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
643 member. Adjust users. Convert term_initted, delete_in_insert_mode,
644 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
645 members to a bitfields.
647 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
649 Don't let call-process be a zombie factory (Bug#12980).
650 Fixing this bug required some cleanup of the signal-handling code.
651 As a side effect, this change also fixes a longstanding rare race
652 condition whereby Emacs could mistakenly kill unrelated processes,
653 and it fixes a bug where a second C-g does not kill a recalcitrant
654 synchronous process in GNU/Linux and similar platforms.
655 The patch should also fix the last vestiges of Bug#9488,
656 a bug which has mostly been fixed on the trunk by other changes.
657 * callproc.c, process.h (synch_process_alive, synch_process_death)
658 (synch_process_termsig, sync_process_retcode):
659 Remove. All uses removed, to simplify analysis and so that
660 less consing is done inside critical sections.
661 * callproc.c (call_process_exited): Remove. All uses replaced
662 with !synch_process_pid.
663 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
664 These take the role of what used to be in unwind-protect arg.
666 (block_child_signal, unblock_child_signal):
667 New functions, to avoid races that could kill innocent-victim processes.
668 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
669 (call_process_kill): Record killed processes as deleted, so that
670 zombies do not clutter up the system. Do this inside a critical
671 section, to avoid a race that would allow the clutter.
672 (call_process_cleanup): Fix code so that the second C-g works again
673 on common platforms such as GNU/Linux.
674 (Fcall_process): Create the child process in a critical section,
675 to fix a race condition. If creating an asynchronous process,
676 record it as deleted so that zombies do not clutter up the system.
677 Do unwind-protect for WINDOWSNT too, as that's simpler in the
678 light of these changes. Omit unnecessary call to emacs_close
679 before failure, as the unwind-protect code does that.
680 * callproc.c (call_process_cleanup):
681 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
682 * process.c (record_deleted_pid): New function, containing
683 code refactored out of Fdelete_process.
684 (Fdelete_process): Use it.
685 (process_status_retrieved): Remove. All callers changed to use
687 (record_child_status_change): Remove, folding its contents into ...
688 (handle_child_signal): ... this signal handler. Now, this
689 function is purely a handler for SIGCHLD, and is not called after
690 a synchronous waitpid returns; the synchronous code is moved to
691 wait_for_termination. There is no need to worry about reaping
692 more than one child now.
693 * sysdep.c (get_child_status, child_status_changed): New functions.
694 (wait_for_termination): Now takes int * status and bool
695 interruptible arguments, too. Do not record child status change;
696 that's now the caller's responsibility. All callers changed.
697 Reimplement in terms of get_child_status.
698 (wait_for_termination_1, interruptible_wait_for_termination):
699 Remove. All callers changed to use wait_for_termination.
700 * syswait.h: Include <stdbool.h>, for bool.
701 (record_child_status_change, interruptible_wait_for_termination):
703 (record_deleted_pid, child_status_changed): New decls.
704 (wait_for_termination): Adjust to API changes noted above.
706 * bytecode.c, lisp.h (Qbytecode): Remove.
707 No longer needed after 2012-11-20 interactive-p changes.
709 2012-12-03 Eli Zaretskii <eliz@gnu.org>
711 * xdisp.c (redisplay_window): If the cursor is visible, but inside
712 the scroll margin, move point outside the margin. (Bug#13055)
714 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
716 * gtkutil.c (my_log_handler): New function.
717 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
719 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
721 * lisp.h (modify_region): Rename to...
722 (modify_region_1): ...new prototype.
723 * textprop.c (modify_region): Now static. Adjust users.
724 * insdel.c (modify_region): Rename to...
725 (modify_region_1): ...new function to work with current buffer.
726 Adjust comment and users. Use true and false for booleans.
728 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
730 * alloc.c (free_save_value): New function.
731 (safe_alloca_unwind): Use it.
732 * lisp.h (free_save_value): New prototype.
733 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
735 (save_excursion_restore): Adjust to match saved data structure.
736 Use free_save_value to offload some work from GC. Drop obsolete
739 2012-12-03 Chong Yidong <cyd@gnu.org>
741 * fileio.c (Vauto_save_list_file_name): Doc fix.
743 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
745 * w32fns.c: Remove prototype of atof.
746 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
748 (file_dialog_callback): Make it UINT_PTR.
750 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
753 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
754 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
757 2012-12-03 Glenn Morris <rgm@gnu.org>
759 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
761 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
763 Fix xpalloc confusion after memory is exhausted.
764 * alloc.c (xpalloc): Comment fix.
765 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
766 and signals an error, do not clear charset_table_size, as
767 charset_table is still valid.
768 * doprnt.c (evxprintf): Clear *BUF after freeing it.
770 Use execve to avoid need to munge environ (Bug#13054).
771 * callproc.c (Fcall_process):
772 * process.c (create_process):
773 Don't save and restore environ; no longer needed.
774 * callproc.c (child_setup):
775 Use execve, not execvp, to preserve environ.
777 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
779 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
781 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
783 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
784 display for sliced images (Bug#10500).
786 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.

791 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
793 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
795 * xdisp.c (window_outdated): Remove eassert since it hits
796 some suspicious corner cases (see Bug#13007 and Bug#13012).
797 (mode_line_update_needed): New function.
798 (redisplay_internal, redisplay_window): Use it.
799 (ensure_selected_frame): New function.
800 (redisplay_internal, unwind_redisplay): Use it.
801 (redisplay_internal): Move comment about buffer_shared...
802 (buffer_shared_and_changed): ...near to its real use.
804 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
806 * callproc.c (Fcall_process): Don't misreport vfork failure.
808 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
810 * callproc.c (Fcall_process): Fix vfork portability problems.
811 Do not assume that fd[0], count, filefd, and save_environ survive
812 vfork. Fix bug whereby wrong errno value could be reported for
813 pipe failure. Some minor cleanups, too, as follows. Move buf and
814 bufsize to the context where they're needed. Change new_argv to
815 be of type char **, as this is more convenient and avoids casts.
816 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
817 Now local constants, not macros.
819 2012-11-18 Kenichi Handa <handa@gnu.org>
821 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
822 for the variable "f".
824 2012-11-13 Kenichi Handa <handa@gnu.org>
826 * font.c (font_unparse_xlfd): Exclude special characters from the
827 generating XLFD name.

852 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
853 highlighting on the frame was cleared. Prevents assertion
854 violations when repeatedly clicking on the "Top" link of the
855 "bread-crumbs" in Info buffers.

869 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
870 between bpos_covered and bpos_max. This fixes cursor display when
871 several display strings follow each other.
873 * .gdbinit (pgx): If the glyph's object is a string, display the
874 pointer to string data, rather than the value of the string object
875 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
877 * indent.c (Fvertical_motion): If the starting position is covered
878 by a display string, return to one position before that, to avoid
879 overshooting it inside move_it_to. (Bug#12930)
881 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

907 (NAMLEN): Remove, replacing with ...
908 (dirent_namelen): New function. All uses changed. Use the GNU macro
909 _D_EXACT_NAMELEN if available, as it's faster than strlen.
910 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
911 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
912 * makefile.w32-in (DIR_H): Remove. All uses replaced with
914 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
915 * ndir.h: Rename to ../nt/inc/dirent.h.
916 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
917 Do not include <dirent.h>; no longer needed.
918 * w32.c: Include <dirent.h> rather than "ndir.h".
920 2012-11-23 Chong Yidong <cyd@gnu.org>
922 * xftfont.c (xftfont_open): Remove duplicate assignment.
924 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
926 * alloc.c (Fgarbage_collect): Unblock input after clearing
927 gc_in_progress to avoid note_mouse_highlight glitch with GC.
928 * frame.h (FRAME_MOUSE_UPDATE): New macro.
929 * msdos.c (IT_frame_up_to_date): Use it here...
930 * w32term.c (w32_frame_up_to_date): ...here...
931 * xterm.c (XTframe_up_to_date): ...and here...
932 * nsterm.m (ns_frame_up_to_date): ...but not here.
933 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
935 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
936 Do not check whether GC is in progress.

940 * xdisp.c (window_buffer_changed): New function.
941 (update_menu_bar, update_tool_bar): Use it to
942 simplify large 'if' statements.
943 (redisplay_internal): Generalize commonly used
944 'tail' and 'frame' local variables.
946 2012-11-22 Eli Zaretskii <eliz@gnu.org>

949 with Windows system header.
951 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
953 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
954 * alloc.c: Assume unistd.h exists.
955 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
956 * sysdep.c (get_current_dir_name): Assume getcwd exists.
957 (getwd) [USG]: Remove; no longer needed.

974 2012-11-21 Eli Zaretskii <eliz@gnu.org>
976 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
977 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
978 Define for the MSVC compiler.
980 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
982 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
983 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
984 dostounix_filename. Prevents crashes down the road, because
985 dostounix_filename assumes it gets a unibyte string.
986 Reported by Michel de Ruiter <michel@sentient.nl>, see

989 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
991 Conflate Qnil and Qunbound for `symbol-function'.

993 * lread.c (init_obarray): Set `function' fields to Qnil.
994 * eval.c (Fcommandp): Ignore Qunbound.
995 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
996 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
997 Test NILP rather than Qunbound.
998 (Ffmakunbound): Set to Qnil.
999 (Fsymbol_function): Never signal an error.
1000 (Finteractive_form): Ignore Qunbound.
1002 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1004 * eval.c (interactive_p): Remove no-longer-used decl.
1006 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1008 * xdisp.c (buffer_shared): Adjust comment.
1009 (buffer_shared_and_changed): New function.
1010 (prepare_menu_bars, redisplay_internal): Use it to
1011 decide whether all windows or frames should be updated.
1012 (window_outdated): New function.
1013 (text_outside_line_unchanged_p, redisplay_window): Use it.
1014 (redisplay_internal): Likewise. Fix indentation.
1016 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1018 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1019 (syms_of_eval): Remove corresponding defsubr.
1020 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1022 2012-11-19 Daniel Colascione <dancol@dancol.org>
1024 * w32fns.c (Fx_file_dialog):
1025 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1026 cygwin_convert_file_name*.
1028 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1029 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1031 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1033 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1035 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1037 * w32select.c: Include w32common.h before w32term.h, so that
1038 windows.h gets included before w32term.h uses some of its
1039 features, see below.
1041 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1043 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1045 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1047 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1049 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1050 (ns_select): Return at once if events are held (Bug#12834).
1052 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1054 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1055 Needed following 2012-10-20 change. (Bug#12902)
1057 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1059 * w32proc.c (waitpid): Remove unused label get_result.
1061 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1063 * makefile.w32-in (SYSWAIT_H): New macro.
1064 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1065 ($(BLD)/sysdep.$(O)): Update dependencies.
1067 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1069 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1070 * callproc.c (relocate_fd): Assume F_DUPFD.
1071 * emacs.c, term.c (O_RDWR): Remove.
1072 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1073 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1074 * nsterm.m: Assume <fcntl.h> exists.
1075 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1076 (create_pty, Fmake_network_process, server_accept_connection)
1077 (wait_reading_process_output, init_process_emacs):
1079 (wait_reading_process_output): Put in a special case for WINDOWSNT
1080 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1081 It's not clear this is needed, but it's a more-conservative change.
1082 (create_process): Assume FD_CLOEXEC.
1083 (create_process, create_pty): Assume O_NOCTTY.
1084 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1085 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1086 Omit if not DOS_NT, since F_GETFL is not defined there.
1087 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1088 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1090 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1091 lack it, since gnulib guarantees this.
1092 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1094 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1096 * w32.c (faccessat): Pretend that directories have the execute bit
1097 set. Emacs expects that, e.g., in files.el:cd-absolute.
1099 * w32proc.c (create_child): Don't clip the PID of the child
1100 process to fit into an Emacs integer, as this is no longer a
1102 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1103 reaping only the process specified by PID argument, if that is
1104 positive. Use PID instead of dead_child to know which process to
1105 reap. Wait for the child to die only if WNOHANG is not in
1107 (sys_select): Don't set dead_child.
1109 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1110 as it is no longer needed.
1112 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1114 (record_child_status_change): Remove the setting of
1115 record_at_most_one_child for the !WNOHANG case.
1117 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1119 Fix problems in ns port found by static checking.
1120 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1121 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1122 not to process group.
1123 (ns_select): Use emacs_write, not write, as that's more robust
1124 in the presence of signals.
1125 (fd_handler:): Check for read errors.
1127 2012-11-16 Glenn Morris <rgm@gnu.org>
1129 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1131 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1133 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1135 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1137 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1138 use the same value of thread handle.
1139 (start_timer_thread): If the timer thread exited (due to error),
1140 clean up by closing the two handles it used. Duplicate the caller
1141 thread's handle here, so it gets duplicated only once, when
1142 launching the timer thread. Set priority of the timer thread, not
1144 (getitimer): Don't duplicate the caller thread's handle here.
1147 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1149 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1152 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1154 Remove no-longer-used pty_max_bytes variable.
1155 * process.c (pty_max_bytes): Remove; unused.
1156 (send_process): Do not set it.
1158 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1160 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1161 Update dependencies.
1163 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1165 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1166 This follows up on the 2012-09-29 patch that removed indirection
1167 for the 'function' field. Reported by Sergey Vinokurov in
1168 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1170 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1172 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1173 different name, as the MS runtime does not have such a function,
1174 and probably never will.) All callers changed. Ignore DIRFD
1175 value if PATH is an absolute file name, to match Posix spec
1176 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1179 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1181 * xdisp.c (echo_area_display, redisplay_internal):
1182 Omit redundant check whether frame_garbaged is set.
1184 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1186 Use faccessat, not access, when checking file permissions (Bug#12632).
1187 This fixes a bug that has been present in Emacs since its creation.
1188 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1189 which must set some sort of record. (Torek's bug report was against
1190 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1191 same common flaw.) See Torek's Usenet posting
1192 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1193 Posted: Fri Apr 8 14:18:56 1983.
1194 * Makefile.in (LIB_EACCESS): New macro.
1196 * callproc.c (init_callproc):
1197 * charset.c (init_charset):
1198 * fileio.c (check_existing, check_executable, check_writable)
1200 * lread.c (openp, load_path_check):
1201 * process.c (allocate_pty):
1203 Use effective UID when checking permissions, not real UID.
1204 * callproc.c (init_callproc):
1205 * charset.c (init_charset):
1206 * lread.c (load_path_check, init_lread):
1207 Test whether directories are accessible, not merely whether they exist.
1208 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1209 * fileio.c (check_existing, check_executable, check_writable)
1211 Use symbolic names instead of integers for the flags, as they're
1213 (check_writable): New arg AMODE. All uses changed.
1214 Set errno on failure.
1215 (Ffile_readable_p): Use faccessat, not stat + open + close.
1216 (Ffile_writable_p): No need to call check_existing + check_writable.
1217 Just call check_writable and then look at errno. This saves a syscall.
1218 dir should never be nil; replace an unnecessary runtime check
1219 with an eassert. When checking the parent directory of a nonexistent
1220 file, check that the directory is searchable as well as writable, as
1221 we can't create files in unsearchable directories.
1222 (file_directory_p): New function, which uses 'stat' on most platforms
1223 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1224 (Ffile_directory_p, Fset_file_times): Use it.
1225 (file_accessible_directory_p): New function, which uses a single
1226 syscall for efficiency.
1227 (Ffile_accessible_directory_p): Use it.
1228 * xrdb.c (file_p): Use file_directory_p.
1229 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1230 * lread.c (openp): When opening a file, use fstat rather than
1231 stat, as that avoids a permissions race. When not opening a file,
1232 use file_directory_p rather than stat.
1233 (dir_warning): First arg is now a usage string, not a format.
1234 Use errno. All uses changed.
1235 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1236 that merely introduced a race.
1237 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1238 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1239 and similarly for the other O_* flags.
1240 * w32.c (sys_faccessat): Rename from sys_access and switch to
1241 faccessat's API. All uses changed.
1242 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1243 (magic_db): Rename from magic_file_p.
1244 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1245 char *, so that we don't have to test for file existence
1246 separately from opening the file for reading. This removes a race
1247 fixes a permission-checking problem, and simplifies the code.
1249 (file_p): Remove; no longer needed.
1251 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1253 Omit glyphs initialization at startup.
1254 * dispnew.c (glyphs_initialized_initially_p): Remove.
1255 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1256 (Fredraw_frame): Move actual code from here...
1257 (redraw_frame): ...to here. Add eassert. Adjust comment.
1258 (Fredraw_display): Use redraw_frame.
1259 * xdisp.c (clear_garbaged_frames): Likewise.
1261 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1263 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1264 passed to pint2str and pint2hrstr to be at most the size of the
1265 frame's decode_mode_spec_buffer. This avoids crashes with very
1266 large values of FIELD_WIDTH argument to decode_mode_spec.
1269 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1271 Fix a race with verify-visited-file-modtime (Bug#12863).
1272 Since at least 1991 Emacs has ignored an mtime difference of no
1273 more than one second, but my guess is that this was to work around
1274 file system bugs that were fixed long ago. Since the race is
1275 causing problems now, let's remove that code.
1276 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1277 whose time stamp is off by no more than a second. Insist that the
1278 file time stamps match exactly.
1280 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1282 * frame.h (struct frame): Convert external_tool_bar member to
1283 1-bit unsigned bitfield.
1284 * termhooks.h (struct terminal): Remove mouse_moved member since
1285 all users are long dead. Adjust comment on mouse_position_hook.
1287 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1289 Simplify by using FOR_EACH_FRAME here and there.
1290 * frame.c (next_frame, prev_frame, other_visible_frames)
1291 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1292 * w32term.c (x_window_to_scroll_bar): Likewise.
1293 * window.c (window_list): Likewise.
1294 * xdisp.c (x_consider_frame_title): Likewise.
1295 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1296 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1297 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1298 * xmenu.c (menubar_id_to_frame): Likewise.
1299 * xselect.c (frame_for_x_selection): Likewise.
1300 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1301 (x_window_to_menu_bar): Likewise.
1302 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1304 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1306 * data.c (Qdefalias_fset_function): Now static.
1308 Another tweak to vectorlike_header change.
1309 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1310 Remove, and replace all uses with ...
1311 (next_in_free_list, set_next_in_free_list):
1312 New functions, which respect C's aliasing rules better.
1314 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1316 * window.c (list4i): Rename from 'quad'. All uses changed.
1317 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1319 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1321 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1322 warning about mixing declarations and code in ISO C90.
1324 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1326 * window.c (Fsplit_window_internal): Set combination limit of
1327 new parent window to t iff Vwindow_combination_limit is t;
1328 fixing a regression introduced with the change from 2012-09-22.
1329 (Fset_window_combination_limit): Fix doc-string.
1331 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1333 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1334 amount when the scroll margins are too large. When scrolling
1335 backwards in the buffer, give up if cannot reach point or the
1336 scroll margin within a reasonable number of screen lines.
1337 Fixes point position in window under scroll-up/down-aggressively when
1338 point is positioned many lines beyond the window top/bottom.
1341 * ralloc.c (relinquish): If real_morecore fails to return memory
1342 to the system, don't crash; instead, leave the last heap
1343 unchanged and return. (Bug#12774)
1345 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1347 * lisp.h (AUTOLOADP): New macro.
1348 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1349 * data.c (Ffset): Remove special ad-advice-info handling.
1350 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1352 (Finteractive_form): Simplify.
1353 (Fquo): Don't insist on having at least 2 arguments.
1354 (Qdefalias_fset_function): New var.
1356 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1358 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1360 * nsfont.m (Qcondensed, Qexpanded): New variables.
1361 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1362 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1364 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1366 Fix recently introduced crash on MS-Windows (Bug#12839).
1367 * w32term.h (struct scroll_bar): Use convenient header.
1368 (SCROLL_BAR_VEC_SIZE): Remove.
1369 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1371 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1373 Tweak last vectorlike_header change.
1374 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1375 vectorlike object on the free list. This is introduced to avoid
1376 some (but not all) pointer casting and aliasing problems, see
1377 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1378 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1380 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1382 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1384 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1385 been removed, so remove them here also.
1387 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1389 * doc.c (Fdocumentation): Handle new property
1390 dynamic-docstring-function to replace the old ad-advice-info.
1392 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1394 * fns.c (Qeql, hashtest_eq): Now static.
1396 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1398 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1399 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1400 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1401 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1403 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1405 Use same hash function for hashfn_profiler as for hash_string etc.
1406 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1407 * lisp.h (sxhash_combine): New inline function, with the contents
1408 of the old SXHASH_COMBINE.
1409 * profiler.c (hashfn_profiler): Use it, instead of having a
1410 special hash function containing a comparison that always yields 1.
1412 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1414 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1415 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1416 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1419 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1421 * image.c (xpm_make_color_table_h): Fix compiler error because
1422 make_hash_table changed.
1424 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1426 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1428 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1430 Use ad-hoc comparison function for the profiler's hash-tables.
1431 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1432 (make_log): Use them.
1433 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1434 call Fequal any more.
1435 (Ffunction_equal): New function.
1436 (cmpfn_profiler, hashfn_profiler): New functions.

1443 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1444 (hash_lookup, hash_remove_from_table): Move assertion checking of
1445 hashfn result here. Check hash-equality before calling cmpfn.
1446 (Fmake_hash_table): Adjust call to make_hash_table.
1447 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
1448 (syms_of_fns): Initialize them.

1453 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
1455 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1457 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1458 value of w32-scroll-lock-modifier is neither nil nor one of the
1459 known key modifiers. (Bug#12806)
1461 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1463 Shrink struct vectorlike_header to the only size field.
1464 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1466 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1467 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1468 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1469 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1470 information from the vector header. Adjust comment.

1480 (enum mem_type): Adjust comment.
1481 (NEXT_IN_FREE_LIST): New macro.
1482 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1483 (Fmake_bool_vector): Likewise.
1484 (struct large_vector): New type to represent allocation unit for
1485 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1486 (large_vectors): Change type to struct large_vector.
1487 (allocate_vector_from_block): Simplify.
1488 (PSEUDOVECTOR_NBYTES): Replace with...
1489 (vector_nbytes): ...new function. Adjust users.
1490 (sweep_vectors): Adjust processing of large vectors.
1491 (allocate_vectorlike): Likewise.
1492 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1493 Add easserts. Adjust XSETPVECTYPESIZE usage.
1494 (allocate_buffer): Use BUFFER_PVEC_INIT.
1495 (live_vector_p): Adjust to match large vector.
1496 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1497 * buffer.h (struct buffer): Add next member.
1498 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1500 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

1506 (xvecsize): New command.
1508 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1510 * keyboard.c (event_to_kboard): Do not dereference
1511 frame_or_window field of SELECTION_REQUEST_EVENT
1512 and SELECTION_CLEAR_EVENT events (Bug#12814).
1513 * xterm.h (struct selection_input_event): Adjust comment.
1515 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1517 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1518 such as Scroll Lock, if the respective keys are treated as
1519 function keys, not as modifiers. This avoids destroying non-ASCII
1520 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1522 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1524 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1526 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1528 Restore some duplicate definitions (Bug#12814).
1529 This undoes part of the 2012-11-03 changes. Some people build
1530 with plain -g rather than with -g3, and they need the duplicate
1531 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1532 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1533 Define as macros, as well as as enums or as constants.
1535 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1537 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1538 to keypad keys (Bug#12816).
1540 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1542 Minor adjustments of recently-changed frame functions.
1543 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1544 known to be a frame (we're in the FRAMEP branch).
1545 * lisp.h (Qframep): Remove decl. frame.h declares this.
1546 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1547 since they're meant for Lisp fixnum values.
1549 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1551 * window.c (Fwindow_combination_limit): Revert to the only
1552 required argument and adjust docstring as suggested in
1553 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1554 by Martin Rudalics <rudalics@gmx.at>.
1556 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1558 Widely used frame validity and checking functions.
1559 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1560 * frame.c (decode_live_frame, decode_any_frame): New functions.
1561 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1562 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1563 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1564 (Fframe_pointer_visible_p): Use decode_any_frame.

1567 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1568 (Fframe_focus): Likewise. Allow zero number of arguments.
1570 (frame_buffer_list, frame_buffer_predicate): Remove.
1571 * lisp.h (frame_buffer_predicate): Remove prototype.
1572 * buffer.c (Fother_buffer): Use decode_any_frame.
1573 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1574 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1575 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1576 (Fclose_font, Ffont_info): Use decode_live_frame.
1577 * fontset.c (check_fontset_name): Likewise.
1578 * terminal.c (Fframe_terminal): Likewise.
1579 * w32fns.c (check_x_frame): Likewise.
1580 * window.c (Fminibuffer_window, Fwindow_at)
1581 (Fcurrent_window_configuration): Likewise.
1582 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1583 Likewise. Allow zero number of arguments. Adjust docstring.
1584 * dispnew.c (Fredraw_frame): Likewise.
1585 * xfaces.c (frame_or_selected_frame): Remove.
1586 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1587 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1588 (Fframe_face_alist): Use decode_live_frame.
1589 * xfns.c (check_x_frame): Likewise.
1591 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1593 * window.c (quad): New function.
1594 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1595 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1596 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1597 (Fwindow_line_height): Use it.
1598 (Fwindow_fringes): Use list3.
1599 (Fwindow_scroll_bars): Use list4.
1600 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1601 (Fwindow_combination_limit): Allow zero number of arguments.
1603 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1605 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1607 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1608 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1609 file descriptor 2 for standard error. (Bug#12805)
1611 2012-11-05 Chong Yidong <cyd@gnu.org>
1613 * process.c (wait_reading_process_output): Revert previous change.
1615 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1617 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1618 This removes code that has been obsolete since around 1990.
1619 * callproc.c (Fcall_process):
1621 * process.c (create_process):
1622 * term.c (dissociate_if_controlling_tty):
1623 Assume setsid exists.
1624 * callproc.c (child_setup): Assume setpgid exists and behaves as
1625 per POSIX.1-1988 or later.
1626 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1627 * emacs.c (shut_down_emacs):
1628 * sysdep.c (sys_suspend, init_foreground_group):
1629 Assume getpgrp behaves as per POSIX.1-1998 or later.
1630 * msdos.c (setpgrp): Remove.
1631 (tcgetpgrp, setpgid, setsid): New functions.
1632 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1633 * term.c (no_controlling_tty): Remove; unused.
1634 * w32proc.c (setpgrp): Remove.
1635 (setsid, tcgetpgrp): New functions.
1637 Simplify by assuming __fpending.
1638 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1639 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1640 Do not assume that __fpending's result fits in int.
1642 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1644 Remove EMACS_OUTQSIZE+sleep hack.
1645 * dispnew.c (update_frame_1): Remove hack for terminals slower
1646 than 2400 bps, which throttled Emacs by having it sleep.
1647 This code hasn't worked since at least 2007, when the multi-tty stuff
1648 was added, and anyway those old terminals are long dead.
1649 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1650 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1652 Fix data-loss with --version (Bug#9574).
1653 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1654 as we can't assume that emacs_strerror is initialized, and strerror
1655 is good enough here.
1656 (main): Invoke atexit earlier, to catch earlier instances of
1657 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1659 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1661 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1662 (keyDown): Remap keypad keys to X11 virtual key codes.
1664 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1666 Fix data-loss with --batch (Bug#9574).
1667 * emacs.c: Include <close-stream.h>.
1668 (close_output_streams): New function.
1669 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1670 and handles errors appropriately.
1671 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1674 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1675 The symptom is a diagnostic "GLib-WARNING **: In call to
1676 g_spawn_sync(), exit status of a child process was requested but
1677 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1678 waitpid(), so exit status can't be returned." The diagnostic
1679 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1680 The real bug is a race condition between Emacs and glib: Emacs
1681 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1682 so that glib can't find it. Work around the bug by invoking
1683 waitpid only on subprocesses that Emacs itself creates.
1684 * process.c (create_process, record_child_status_change):
1685 Don't use special value -1 in pid field, as the caller now must
1686 know the pid rather than having the callee infer it.
1687 The inference was sometimes incorrect anyway, due to another race.
1688 (create_process): Set new 'alive' member if child is created.
1689 (process_status_retrieved): New function.
1690 (record_child_status_change): Use it.
1691 Accept negative 1st argument, which means to wait for the
1692 processes that Emacs already knows about. Move special-case code
1693 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1694 processes that have already been waited for, by testing and
1695 clearing new 'alive' member.
1696 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1697 now does this internally.
1698 (handle_child_signal): Let record_child_status_change do all
1699 the work, since we do not want to reap all exited child processes,
1700 only the child processes that Emacs itself created.
1701 * process.h (Lisp_Process): New boolean member 'alive'.
1703 Omit duplicate definitions no longer needed with gcc -g3.
1704 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1705 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1706 Define only as macros. There's no longer any need to also define
1707 these symbols as enums or as constants, since we now assume
1708 gcc -g3 when debugging.
1710 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1712 * lisp.mk: Adjust comments to the fact that term/internal is now
1713 loaded from loadup.el.
1715 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1716 (msdos_fatal_signal): New function.
1717 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1720 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1721 for GCC versions before 4.
1722 (emacs_raise): Define to call msdos_fatal_signal.
1724 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1725 iterator when starting in the middle of a display or overlay
1728 2012-11-03 Chong Yidong <cyd@gnu.org>
1730 * process.c (wait_reading_process_output): Clean up the last
1733 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1735 * process.c (wait_reading_process_output): Avoid a race condition
1736 with SIGIO delivery (Bug#11536).
1738 2012-11-03 Chong Yidong <cyd@gnu.org>
1740 * buffer.c (cursor_type): Untabify docstring.
1742 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1744 * frame.h (struct frame): Drop can_have_scroll_bars member
1745 which is meaningless for a long time. Adjust comments.
1746 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1747 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1749 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1751 * window.c (decode_next_window_args): Update window arg after
1752 calling decode_live_window and so fix crash reported at
1753 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1754 by Juanma Barranquero <lekktu@gmail.com>.
1755 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1756 * font.c (Ffont_at): Likewise.
1758 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1760 * widget.c (resize_cb): New function.
1761 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1762 (EmacsFrameResize): Check if all is up to date before changing frame
1765 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1767 Implement backtrace output for fatal errors on MS-Windows.
1768 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1769 (BACKTRACE_LIMIT_MAX): New macro.
1770 (w32_backtrace): New function.
1771 (emacs_abort): Use w32_backtrace when the user chooses not to
1772 attach a debugger. Update the text of the abort dialog.
1774 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1776 Window-related stuff cleanup here and there.
1777 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1778 Use decode_any_window.
1779 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1780 * xdisp.c (Fformat_mode_line): Likewise.
1781 * font.c (Ffont_at): Use decode_live_window.
1782 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1783 * window.c (decode_next_window_args): Likewise.
1784 (decode_any_window): Remove static.
1785 * window.h (decode_any_window): Add prototype.
1786 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1787 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1790 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1792 Remove pad from struct input_event.
1793 * termhooks.h (struct input_event): Remove padding field.
1795 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1796 member is never cons for a long time. Adjust comment.
1797 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1798 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1799 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1800 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1802 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1804 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1806 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1808 Fix crash when using Emacs as commit editor for git (Bug#12697).
1809 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1810 and it is configured in conf_post.h.
1811 (Fcall_process): Don't invoke both setsid and setpgid; the former
1812 is enough, if it exists.
1813 * callproc.c (Fcall_process, child_setup):
1814 * process.c (create_process): Use setpgid.
1815 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1817 * dispnew.c (init_display): Initialize the foreground group
1818 if we are running a tty display.
1819 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1820 * lisp.h (init_foreground_group): New decl.
1821 * sysdep.c (inherited_pgroup): New static var.
1822 (init_foreground_group, tcsetpgrp_without_stopping)
1823 (narrow_foreground_group, widen_foreground_group): New functions.
1824 (init_sys_modes): Narrow foreground group.
1825 (reset_sys_modes): Widen foreground group.
1827 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1829 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1831 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1833 * minibuf.c (read_minibuf): Restore current buffer since
1834 choose_minibuf_frame calling Fset_frame_selected_window may
1835 change it (Bug#12766).
1837 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1839 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1841 2012-10-30 Kenichi Handa <handa@gnu.org>
1843 * font.c (Ffont_at): If WINDOW is specified and it is not
1844 displaying the current buffer, signal an error.
1846 2012-10-29 Daniel Colascione <dancol@dancol.org>
1848 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1849 In preparation for fixing bug#12739, move these functions from
1852 * coding.h, coding.c: ... to here, and compile them only when
1853 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1854 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1856 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1858 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1859 (timer_loop, getitimer, setitimer): Use it instead of
1860 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1862 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1865 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1867 * nsterm.m (NO_APPDEFINED_DATA): New define.
1868 (last_appdefined_event_data): New variable
1869 (last_appdefined_event): Remove.
1870 (ns_select): Initialize t from last_appdefined_event_data instead
1871 of [last_appdefined_event data1].

1877 * frame.c (x_set_font): Catch internal error.
1879 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1881 Avoid overflow in w32 implementation of interval timers.
1882 When possible, for ITIMER_PROF count only times the main thread
1884 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1885 'volatile ULONGLONG' types. All the other data which was
1886 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1887 (GetThreadTimes_Proc): New typedef.
1888 (w32_get_timer_time): New function, returns a suitable time value
1890 (timer_loop): Enter critical section when accessing ULONGLONG
1891 values of the itimer_data struct, as these accesses are no longer
1892 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1893 Remove unused variable.
1894 (init_timers): Initialize s_pfn_Get_Thread_Times.
1895 (start_timer_thread): Don't assign itimer->caller_thread here.

1902 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1903 mouse movement events if the menu bar is active. This avoids
1904 producing a busy "hour-glass" cursor by Windows if the mouse
1905 pointer is positioned over a tooltip shown for some menu item.
1907 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>

1910 * emacs.c (shut_down_emacs) [!DOS_NT]:
1911 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1912 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1913 Use pid_t, not int, to store process IDs, as 'int'
1914 is not wide enough on a few platforms (e.g., AIX and IRIX).
1916 2012-10-23 Kenichi Handa <handa@gnu.org>
1918 The following change is to make face-font-rescale-alist work

1944 * frame.c (Fmouse_position, Fmouse_pixel_position):
1945 * xdisp.c (produce_stretch_glyph):
1946 Declare local vars only when they're needed.
1947 This is clearer and avoids a warning on OpenBSD about unused vars.

1949 This is safer, and avoids OpenBSD warnings about unused vars.
1950 * keyboard.c (record_menu_key): Remove unnecessary decl.
1951 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1952 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1953 as our definition clashes with OpenBSD's.
1954 * xfaces.c (load_face_colors, check_lface_attrs)
1955 (get_lface_attributes_no_remap, get_lface_attributes)
1956 (lface_fully_specified_p, x_supports_face_attributes_p)
1957 (tty_supports_face_attributes_p, face_fontset, realize_face)
1958 (realize_x_face, realize_tty_face):
1959 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1960 merely Lisp_Object *. This is more informative and avoids
1961 a warning on OpenBSD about accessing beyond an object's size.
1963 2012-10-20 Chong Yidong <cyd@gnu.org>
1965 * lread.c (Fload): Doc fix (Bug#12592).

1991 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1992 (staticpro): If we run out of staticpro slots, die with an
1993 informative error instead of just calling emacs_abort.
1995 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1997 Fix two flaws reported by Dmitry Antipov.

2255 the same pointer-to-int (now pointer-to-boolean) &input_pending,

2308 2012-10-08 Daniel Colascione <dancol@dancol.org>
2310 * xdisp.c (start_hourglass): Call w32_note_current_window when

2312 build that caused Emacs to display the hourglass cursor forever.
2314 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2315 which is broken under remote desktop, calculate the number of
2316 colors available for a display based on the display's number of

2350 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2352 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2354 2012-10-08 Daniel Colascione <dancol@dancol.org>
2356 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2357 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2358 accidental message numbering hole. Change other messages to
2361 * w32select.h (HAVE_W32SELECT): Remove.
2363 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2364 w32common.h instead of w32heap.h.
2366 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2367 (get_allocation_unit, get_processor_type, get_w32_major_version)
2368 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2369 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2370 (OS_NT, os_subtype, cache_system_info): Move declarations to
2373 * w32heap.c: Include w32common.h.
2374 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2375 (w32_minor_version, w32_build_number, w32_subtype):
2376 Remove duplicate definitions.
2378 * w32fns.c: Include w32common.h; include w32heap.h only in
2381 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2382 Use `report_file_error' instead of `error' in order to better
2383 inform users of what went wrong. Increase NTGUI_UNICODE file
2384 dialog box file name length to 32k, the maximum allowed by the NT
2387 * w32common.h: New file.
2388 (ROUND_UP, ROUND_DOWN, get_page_size)
2389 (get_allocation_unit, get_processor_type, get_w32_major_version)
2390 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2391 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2392 (OS_NT, os_subtype, cache_system_info): Move here.
2394 * unexw32.c, unexcw.c: Include w32common.h.
2396 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2397 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2398 to call syms_of_w32select.
2400 * cygw32.h: Remove obsolete EXFUN declarations.
2402 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2404 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2405 of w32inevt.o from SOME_MACHINE_OBJECTS.
2407 2012-10-08 Daniel Colascione <dancol@dancol.org>
2409 * image.c: Permanent fix for JPEG compilation issue --- limit
2410 jpeglib `boolean' redefinition to Cygwin builds.
2412 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2414 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2416 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2419 2012-10-08 Daniel Colascione <dancol@dancol.org>
2421 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2422 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2423 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2424 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2425 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2426 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2427 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2428 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2429 now a supported configuration.
2431 * Makefile.in: consolidate image variables into LIBIMAGE; add
2432 W32_OBJ and W32_LIBS. Compile new files.
2435 (_DebPrint) declare tracing facility for W32 debugging. We need
2436 to unify tracing later.
2438 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2439 unconditional use of W32 Unicode functions. Cygwin runs only on
2440 100% Unicode operating systems.
2442 * cygw32.c: New file. Define Cygwin-specific facilities.
2443 (Fcygwin_convert_path_to_windows)
2444 (Fcygwin_convert_path_from_windows): New user functions for
2445 accessing Cygwin path-munging routines.
2447 * cygw32.h: New file.
2448 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2449 UTF-16LE strings temporarily inside non-Lisp-visible string
2452 (w32_strerror): Just what it says on the tin.
2454 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2455 also run for Cygwin; both systems have the same problem with using
2456 GUI facilities in a forked child. Also call syms_of_cygw32,
2457 syms_of_w32select in correct places.
2459 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2460 needs fork-then-exec for daemon launching.
2462 * font.h: Include frame.h.
2464 * image.c: Use the image library cache machinery only when we're
2465 compiling for native WINDOWSNT; Cygwin can use shared libraries
2466 like any other Unixlike system.
2468 * keyboard.c: Clarify a comment regarding the input loop.
2470 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2471 functions directly instead of trying to detect at runtime that our
2472 host operating system supports them. We make this change for two
2473 reasons: Cygwin lacks support for the multibyte character
2474 conversion functions used by the legacy menu code, and Cygwin
2475 never needs to rely on non-Unicode APIs.
2477 * unexw32.c (hinst): Declare extern.
2479 * w32.c: Change header order;
2480 (w32_strerror): Move to w32fns.c because we need it for
2481 non-WINDOWSNT builds.
2483 * w32.h: Add #error macro to make sure we don't include w32.h for
2484 Cygwin builds. Remove w32select declarations.
2486 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2487 w32fns.c. w32console.c is WINDOWSNT-only.
2489 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2490 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2492 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2493 (w32_major_version, w32_minor_version, w32_build_number)
2494 (os_subtype, sound_type): Define here
2495 (w32_defined_color): Make color parameter const for consistency
2496 with other _defined_color functions.
2497 (w32_createwindow): Unconditionally call w32_init_class instead of
2498 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2499 through the code is complex and unnecessary because class
2500 registration is practically free.
2501 (w32_name_of_message): New EMACSDEBUG-only function.
2502 (Fset_message_beep): Move here
2503 (Fx_open_connection): Require that the display name for Windows be
2504 "w32" for consistency, emacsclient disambiguation, and maybe, one
2505 day, multi-window-system support.
2506 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2507 Cygwin files for W32 GUI facilities, since these clearly don't
2508 expect Cygwin names.
2509 (_DebPrint): Define.
2510 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2511 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2512 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2513 (w32_last_error): Remove.
2515 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2517 * w32heap.c (syspage_mask): Declare here.
2518 (cache_system_info): Remove.
2520 * w32inevt.c (faked_key): Define globally, not statically.
2521 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2522 (w32_console_toggle_lock_key): Move to w32fns.c.
2524 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2526 * w32proc.c (_DebPrint): Move to w32fns.c.
2527 * w32select.c: Include string.h, stdio.h for Cygwin.
2528 * w32select.h: New File.
2530 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2532 (w32_message_fd): New variable. Under Cygwin, holds the file
2533 descriptor the system used to tell us about pending thread
2536 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2537 that prevented compilation under non-WINDOWSNT systems.
2539 (w32_initialize): Open /dev/windows and assign it to
2540 w32_message_fd. Provide w32 feature.
2542 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2543 (WM_EMACS_INPUT_READY): add.
2544 (prepend_msg, w32_message_fd): Declare globally.
2547 (keyboard_handle): Use only when WINDOWSNT.
2548 (notify_msg_ready): New function. Posts a message to the main
2549 thread's message queue under CYGWIN, which wakes up the main
2550 thread from select(2) by making the /dev/windows file descriptor
2551 ready. Under WINDOWSNT, it sets an event the same way the old
2554 (post, prepend_msg): Actually call notify_msg_ready instead of
2555 setting the input event directly.
2557 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2559 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2560 but it still has blocs in it, don't return it to the system,
2561 instead of aborting. (Bug#12402)
2563 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2565 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2567 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2568 MAC_OS_X_VERSION_10_6.
2569 (syms_of_nsterm): Remove comment about Panther and above for
2571 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2572 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2573 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2575 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2576 MAC_OS_X_VERSION_10_4.
2578 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2579 MAC_OS_X_VERSION_10_2.
2581 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2583 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2584 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2586 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2587 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2588 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2589 Remove ns_in_resize check.
2590 (ns_clear_frame_area): Remove resize handle code.
2592 * nsfns.m (ns_in_resize): Remove.
2593 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2594 Remove ns_in_resize check.
2596 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2598 Improve sys_siglist detection.
2599 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2600 defined as a macro, as is done in Solaris.
2601 (sys_siglist_entries): New macro.
2602 (save_strsignal): Use it.
2603 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2604 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2606 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2608 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2609 fullscreen/Fullscreen.
2611 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2612 tobar_height is new.
2614 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2615 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2616 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2617 (windowDidResize:): Check for correct window if old style fullscreen.
2618 Capitalize word in comment. Remove incorrect comment.
2619 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2620 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2621 error in drawing background.
2622 (toggleFullScreen:): Remove comment. Rearrange calls.
2623 Set toolbar values to zero, save old height in tobar_height.
2624 Restore tool bar height when leaving fullscreen.
2625 (canBecomeMainWindow): New function.
2627 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2629 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2631 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2633 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2635 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2636 that time stamps of directories could also be changed.
2637 Don't request the too broad GENERIC_WRITE, only the more restrictive
2638 FILE_WRITE_ATTRIBUTES access rights.
2640 * fileio.c (Fset_file_times): Special-case ignoring errors for
2641 directories only on MSDOS, not on MS-Windows.
2643 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2645 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2647 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2649 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2650 see whether CreateFile failed.
2652 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2654 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2655 to avoid similar races.
2656 * keyboard.c (pending_signals): Now bool, not int.
2658 Port timers to OpenBSD, plus check for timer failures.
2659 OpenBSD problem reported by Han Boetes.
2660 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2662 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2663 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2664 like OpenBSD, which has timer_settime but does not declare it.
2665 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2666 whether to use itimerspec-related primitives. All uses of
2667 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2669 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2671 * profiler.c (handle_profiler_signal): Fix a malloc race
2672 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2674 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2676 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2678 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2680 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2681 consistent with the change in return value of 'safe_strsignal'.
2683 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2685 Prefer plain 'static' to 'static inline' (Bug#12541).
2686 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2687 (bidi_set_sor_type, bidi_push_embedding_level)
2688 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2689 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2690 (bidi_cache_search, bidi_cache_ensure_space)
2691 (bidi_cache_iterator_state, bidi_cache_find)
2692 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2693 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2694 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2695 Now 'static', not 'static inline'.
2697 Count overruns when profiling; change units to ns.
2698 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2699 Give extra weight to samples after overruns, to attempt to count
2700 the time more accurately.
2701 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2702 the underlying primitives nominally do ns.
2703 (Fprofiler_cpu_start): Document the change. Mention that
2704 the sampling intervals are only approximate.
2706 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2708 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2710 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2711 case for the special 0 coding-system.
2713 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2714 (Fmake_overlay): Remove redundant tests.
2715 (fix_start_end_in_overlays): Remove redundant recentering.
2717 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2719 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2720 Update dependencies.
2722 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2724 Fix a malloc race condition involving strsignal.
2725 A signal can arrive in the middle of a malloc, and Emacs's signal
2726 handler can invoke strsignal, which can invoke malloc, which is
2727 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2728 Fix it by altering the signal handler so that it does not invoke
2730 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2731 * process.c (status_message): Use const pointer, in case strsignal
2732 is #defined to safe_strsignal.
2733 * sysdep.c (sys_siglist, init_signals): Always define and
2734 initialize a substitute sys_siglist if the system does not define
2735 one, even if HAVE_STRSIGNAL.
2736 (safe_strsignal): Rename from strsignal. Always define,
2737 using sys_siglist. Return a const pointer.
2738 * syssignal.h (safe_strsignal): New decl.
2739 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2741 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2743 * w32proc.c (timer_loop): Fix code that waits for timer
2744 expiration, to avoid high CPU usage.
2746 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2748 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2749 (sweep_weak_table): Remove redundant prototypes.
2751 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2753 * emacs.c: Move the inclusion of TERM_HEADER after including
2754 windows.h on WINDOWSNT. This avoids compilation problems with
2757 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2759 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2760 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2761 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2762 as the previous version used 'void *'.
2764 * ralloc.c (ROUNDUP): Fix last change.
2765 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2768 * w32proc.c <disable_itimers>: New static flag.
2769 (init_timers): Initialize it to zero, after creating the critical
2770 sections used by the timer threads.
2771 (term_timers): Set to 1 before deleting the critical sections.
2772 (getitimer, setitimer): If disable_itimers is non-zero, return an
2773 error indication without doing anything. Reported by Fabrice
2774 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2775 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2777 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2780 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2781 term_ntproc after all the other bookkeeping, to get timers working
2782 as long as possible.
2784 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2786 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2787 Suggested by Juri Linkov in
2788 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2790 Prefer plain 'static' to 'static inline' (Bug#12541).
2791 With static functions, modern compilers inline pretty well by
2792 themselves; advice from programmers often hurts as much as it helps.
2793 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2794 this change shrinks the text size of the Emacs executable by 1.1%
2795 without affecting CPU significantly in my benchmark.
2796 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
2797 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
2798 (mark_maybe_object, mark_maybe_pointer, bounded_number):
2799 * buffer.c (bset_abbrev_mode, bset_abbrev_table)
2800 (bset_auto_fill_function, bset_auto_save_file_format)
2801 (bset_auto_save_file_name, bset_backed_up, bset_begv_marker)

3094 for consistency with other handlers.
3095 (setup_cpu_timer): New function, with much of what used to be in

3097 Prefer timer_settime if available, and prefer
3098 thread cputime clocks, then process cputime clocks, then
3099 monotonic clocks, to the old realtime clock. Use make_timeval
3100 to round more-correctly when falling back to setitimer.
3101 (Fprofiler_cpu_start): Use it.
3102 (Fprofiler_cpu_stop): Prefer timer_settime if available.

3168 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3169 Since this stuff is now private to charset.c, there's no need for
3170 a public macro and no need to inline by hand.

3278 image.c, indent.c: Use bool for booleans.
3279 * dispextern.h (struct image_type): Members valid_p, load, init
3280 now return bool, not int. All uses changed.
3281 * image.c: Omit unnecessary static decls.
3282 (x_create_bitmap_mask, x_build_heuristic_mask):
3283 Return void, not int, since callers don't care about the return value.

3318 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3320 Move pid_t related decls out of lisp.h.
3321 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3322 (interruptible_wait_for_termination):
3323 Move these decls from lisp.h to syswait.h, since they use pid_t.
3324 Needed on FreeBSD; see Herbert J. Skuhra in
3325 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3326 * callproc.c: Include syswait.h.

3346 Use bool for boolean.
3347 * gtkutil.c (xg_update_frame_menubar):
3348 * xmenu.c (update_frame_menubar):
3349 Return void, not int, since caller ignores return value.

3353 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3355 * makefile.w32-in (BLOCKINPUT_H): Remove.

3372 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3374 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3375 fatal_error_backtrace.
3377 * w32proc.c (sys_kill): Undo last change: don't do anything when
3378 invoked to deliver SIGABRT to our own process. This is now
3379 handled by emacs_raise.
3381 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3383 * w32term.c (w32_read_socket): Remove leftover reference to
3384 interrupt_input_pending.
3386 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3388 Do not use SA_NODEFER.
3389 Problem reported by Dani Moncayo in
3390 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3392 * sysdep.c (emacs_abort): Do not reset signal handler.
3393 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3394 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3395 wanted even on POSIXish hosts, and it doesn't work on Windows.
3397 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3399 * xterm.c (x_term_init): Call fixup_locale before and after calling
3400 gtk_init (Bug#12392).
3402 2012-09-23 Chong Yidong <cyd@gnu.org>
3404 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3405 Vdynamic_library_alist.
3407 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3408 (Fgnutls_available_p): Caller changed.
3410 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3411 (Flibxml_parse_xml_region): Likewise.
3413 * dispextern.h (struct image_type): Remove arg from init function.
3415 * image.c (Finit_image_library, lookup_image_type)
3416 (define_image_type): Remove now-unneeded second arg.
3417 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3418 (init_tiff_functions, init_gif_functions, init_svg_functions):
3419 Arglist and w32_delayed_load calling convention changed.
3420 (gs_type): Remove init_gs_functions; there is no such function.
3421 (valid_image_p, make_image): Fix caller to lookup_image_type.
3423 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3425 Simplify and avoid signal-handling races (Bug#12471).
3427 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3428 Avoid recursive loop if there's a fatal error in the function itself.
3429 * atimer.c (pending_atimers):
3430 * blockinput.h: Don't include "atimer.h"; no longer needed.
3431 (interrupt_input_pending): Remove. All uses removed.
3432 pending_signals now counts both atimers and ordinary interrupts.
3433 This is less racy than having three separate pending-signal flags.
3434 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3436 Rename from their upper-case counterparts BLOCK_INPUT,
3437 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3438 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3439 This makes it easier to access volatile variables more accurately.
3440 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3441 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3442 that's more reliable if the code is buggy and sets
3443 interrupt_input_blocked to a negative value. All uses changed.
3444 * atimer.c (deliver_alarm_signal):
3445 Remove. No need to deliver this to the parent; any thread can
3446 handle this signal now. All uses replaced by underlying handler.
3447 * atimer.c (turn_on_atimers):
3448 * dispnew.c (handle_window_change_signal):
3449 * emacs.c (handle_danger_signal):
3450 * keyboard.c (kbd_buffer_get_event):
3451 Don't reestablish signal handler; not needed with sigaction.
3452 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3454 Rework to avoid unnecessary accesses to volatile variables.
3455 (UNBLOCK_INPUT_TO): Now a function.
3456 (totally_unblock_input, unblock_input): New decls.
3457 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3458 (init_data): Remove. Necessary stuff now done in init_signal.
3459 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3460 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3461 (fatal_error_code): Remove; no longer needed.
3462 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3463 it doesn't always backtrace. All uses changed. No need to reset
3464 signal to default, since sigaction and/or die does that for us now.
3465 Use emacs_raise (FOO), not kill (getpid (), FOO).
3466 (main): Check more-accurately whether we're dumping.
3467 Move fatal-error setup to sysdep.c
3468 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3469 * gtkutil.c (xg_get_file_name, xg_get_font):
3470 Remove no-longer-needed signal-mask manipulation.
3471 * keyboard.c, process.c (POLL_FOR_INPUT):
3472 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3473 * keyboard.c (read_avail_input): Remove.
3474 All uses replaced by gobble_input.
3475 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3476 (kbd_buffer_store_event_hold, gobble_input):
3477 (record_asynch_buffer_change) [USABLE_SIGIO]:
3478 (store_user_signal_events):
3479 No need to mess with signal mask.
3480 (gobble_input): If blocking input and there are terminals, simply
3481 set pending_signals to 1 and return. All hooks changed to not
3482 worry about whether input is blocked.
3483 (process_pending_signals): Clear pending_signals before processing
3484 them, in case a signal comes in while we're processing.
3485 By convention callers now test pending_signals before calling us.
3486 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3487 New functions, to support changes to blockinput.h.
3488 (handle_input_available_signal): Now extern.
3489 (reinvoke_input_signal): Remove. All uses replaced by
3491 (quit_count): Now volatile, since a signal handler uses it.
3492 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3493 All callers changed. Block SIGINT only if not already blocked.
3494 Clear sigmask reliably, even if Fsignal returns, which it can.
3495 Omit unnecessary accesses to volatile var.
3496 (quit_throw_to_read_char): No need to restore sigmask.
3497 * keyboard.c (gobble_input, handle_user_signal):
3498 * process.c (wait_reading_process_output):
3499 Call signal-handling code rather than killing ourselves.
3500 * lisp.h: Include <float.h>, for...
3501 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3502 (pending_signals): Now volatile.
3503 (syms_of_data): Now const if IEEE floating point.
3504 (handle_input_available_signal) [USABLE_SIGIO]:
3505 (terminate_due_to_signal, record_child_status_change): New decls.
3506 * process.c (create_process): Avoid disaster if memory is exhausted
3507 while we're processing a vfork, by tightening the critical section
3509 (send_process_frame, process_sent_to, handle_pipe_signal)
3510 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3512 (send_process): No need for setjmp/longjmp any more, since the
3513 SIGPIPE stuff is now gone. Instead, report an error if errno
3515 (record_child_status_change): Now extern. PID and W are now args.
3516 Return void, not bool. All callers changed.
3517 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3518 Remove. All uses removed. This bug should be fixed now in a
3520 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3521 and record the child status change directly. This avoids the
3522 need to futz with the signal mask.
3523 (process_fatal_action): Move here from emacs.c.
3524 (emacs_sigaction_flags): New function, containing
3525 much of what used to be in emacs_sigaction_init.
3526 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3527 caught by emacs, to make races less likely.
3528 (deliver_process_signal): Rename from handle_on_main_thread.
3530 (BACKTRACE_LIMIT_MAX): Now at top level.
3531 (thread_backtrace_buffer, threadback_backtrace_pointers):
3533 (deliver_thread_signal, deliver_fatal_thread_signal):
3534 New functions, for more-accurate delivery of thread-specific signals.
3535 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3536 (deliver_arith_signal): Handle in this thread, not
3537 in the main thread, since it's triggered by this thread.
3538 (maybe_fatal_sig): New function.
3539 (init_signals): New arg DUMPING so that we can be more accurate
3540 about whether we're dumping. Caller changed.
3541 Treat thread-specific signals differently from process-general signals.
3542 Block all signals while handling fatal error; that's safer.
3543 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3545 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3546 Ignore SIGPIPE unless batch.
3547 (emacs_backtrace): Output backtrace for the appropriate thread,
3548 which is not necessarily the main thread.
3549 * syssignal.h: Include <stdbool.h>.
3550 (emacs_raise): New macro.
3551 * xterm.c (x_connection_signal): Remove; no longer needed
3552 now that we use sigaction.
3553 (x_connection_closed): No need to mess with sigmask now.
3554 (x_initialize): No need to reset SIGPIPE handler here, since
3555 init_signals does this for us now.
3557 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3559 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3560 background rect may be larger (Bug#12245).
3562 2012-09-23 Chong Yidong <cyd@gnu.org>
3564 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3566 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3568 * .gdbinit: Just stop at fatal_error_backtrace.
3569 See Stefan Monnier's request in
3570 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3571 Remove no-longer-used query of system type.
3573 2012-09-22 Chong Yidong <cyd@gnu.org>
3575 * search.c (Freplace_match): Doc fix (Bug#12325).
3577 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3579 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3580 (Fline_end_position): Doc fix.
3582 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3584 2012-09-22 Chong Yidong <cyd@gnu.org>
3586 * dispextern.h (struct image_type): Add new slot, storing a type
3587 initialization function.
3589 * image.c (define_image_type): Call the image initializer function
3590 if it is defined. Arguments and return value changed.
3591 (valid_image_p, make_image): Callers changed.
3592 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3593 (gif_type, imagemagick_type, svg_type, gs_type):
3594 Add initialization functions.
3595 (Finit_image_library): Call lookup_image_type.
3596 (CHECK_LIB_AVAILABLE): Macro deleted.
3597 (lookup_image_type): Call define_image_type here, rather than via
3598 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3599 (syms_of_image): Move define_image_type calls for xbm_type and
3600 pbm_type to lookup_image_type.
3602 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3604 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3605 'idle_timers' from here ...
3606 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3607 lists, to avoid infloops when the timer does something stupid,
3608 like reinvoke itself with the same or smaller time-out.
3611 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3613 * window.c (Fsplit_window_internal): Handle only Qt value of
3614 Vwindow_combination_limit separately.
3615 (Qtemp_buffer_resize): New symbol.
3616 (Vwindow_combination_limit): New default value.
3619 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3621 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3622 the new overlay string. (Bug#10159)
3624 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3626 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3627 or that fprintf is async-signal-safe. POSIX doesn't require
3630 2012-09-22 Chong Yidong <cyd@gnu.org>
3632 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3635 2012-09-22 Kenichi Handa <handa@gnu.org>
3637 * composite.c (composition_reseat_it): Handle the case that a
3638 grapheme cluster is not covered by a single font (Bug#12352).
3640 2012-09-21 Chong Yidong <cyd@gnu.org>
3642 * image.c (define_image_type): Avoid adding duplicate types to
3643 image_types (Bug#12463). Suggested by Jörg Walter.
3645 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3647 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3648 (print_load_command_name): Add case LC_DATA_IN_CODE.
3649 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3651 2012-09-21 Glenn Morris <rgm@gnu.org>
3653 * eval.c (Frun_hook_with_args_until_success)
3654 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3656 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3658 * fileio.c (Ffile_selinux_context): Only call freecon when
3659 lgetfilecon succeeded.
3660 (Fset_file_selinux_context): Likewise. (Bug#12444)
3662 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3664 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3665 reordering, locate the cursor by calling set_cursor_from_row; if
3666 that fails, clear the desired glyph matrix before returning a
3667 failure indication to the caller. Fixes leaving garbled display
3668 when fast scrolling with a down-key. (Bug#12403)
3669 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3670 scrolling through multibyte text.
3672 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3674 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3675 calling mark_vectorlike since that's the one that marks the window.
3676 (mark_discard_killed_buffers): Mark the final cdr.
3677 * window.h (struct window): Move prev/next_buffers to the
3678 non-standard fields.
3679 * window.c (make_window): Initialize prev/next_buffers manually.
3681 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3683 Omit unused arg EXPECTED from socket hooks.
3684 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3685 * nsterm.m (ns_term_init):
3686 * termhooks.h (struct terminal.read_socket_hook):
3687 * w32inevt.c (w32_console_read_socket):
3688 * w32term.c (w32_read_socket):
3689 * xterm.c (XTread_socket):
3690 Omit unused arg EXPECTED. All callers changed.
3691 (store_user_signal_events): Return void, not int, since callers no
3692 longer care about the return value. All uses changed.
3694 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3696 * w32gui.h (XParseGeometry): Do not declare.
3698 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3700 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3701 Ignore 'expected'. See Eli Zaretskii in
3702 <http://bugs.gnu.org/12471#8> (last line).
3704 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3705 (XParseGeometry): Now static. Substitute extremal values for
3706 values that are out of range.
3708 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3710 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3712 * nsfns.m (XParseGeometry): Remove.
3713 (Fx_create_frame): Call x_set_offset to correctly interpret
3714 top_pos in geometry.
3716 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3717 (Fx_parse_geometry): If there is a space in string, call
3718 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3720 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3722 * search.c (scan_buffer): Use character positions in calls to
3723 region_cache_forward and region_cache_backward, not byte
3724 positions. (Bug#12196)
3726 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3727 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3729 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3730 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3731 emacs_blocked_malloc, now deleted.
3733 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3735 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3736 The workaround was for improving performance on Solaris 2.4, but
3737 is getting in the way now. Emacs will still work if someone is
3738 still running Solaris 2.4 in a museum somewhere; Sun dropped
3739 support for Solaris 2.4 in 2003.
3740 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3741 * process.c (create_process) [HAVE_WORKING_VFORK]:
3742 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3743 since Emacs no longer uses vfork on that platform.
3745 2012-09-17 Glenn Morris <rgm@gnu.org>
3747 * emacs.c: Use COPYRIGHT.
3749 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3751 Remove configure's --without-sync-input option (Bug#12450).
3752 When auditing signal-handling in preparation for cleaning it up,
3753 I found that SYNC_INPUT has race conditions and would be a real
3754 pain to fix. Since it's an undocumented and deprecated
3755 configure-time option, now seems like a good time to remove it.
3756 Also see <http://bugs.gnu.org/11080#16>.
3757 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3758 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3759 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3760 (malloc_hysteresis):
3761 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3762 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3763 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3764 (dont_register_blocks, bytes_used_when_reconsidered)
3765 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3766 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3767 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3768 Remove. All uses removed.
3769 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3770 implementation, one that depends on whether the new macro
3771 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3773 * atimer.c (run_timers, handle_alarm_signal):
3774 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3775 (handle_async_input, process_pending_signals)
3776 (handle_input_available_signal, init_keyboard):
3777 * nsterm.m (ns_read_socket):
3778 * process.c (wait_reading_process_output):
3779 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3780 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3782 * xterm.c (XTread_socket):
3784 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3785 * eval.c (handling_signal): Remove. All uses removed.
3786 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3787 All uses replaced with the SYNC_INPUT version.
3788 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3790 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3793 * font.c (Ffont_shape_gstring): Remove unused local.
3795 2012-09-16 Glenn Morris <rgm@gnu.org>
3797 * Makefile.in (clean): No longer run nextstep's clean.
3799 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3801 (ns-app): Move here from ns.mk, and simplify.
3802 (clean): Simplify nextstep entry.
3803 * ns.mk: Remove file.
3805 2012-09-17 Kenichi Handa <handa@gnu.org>
3807 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3808 not covert the last few charactes.
3810 2012-09-16 Kenichi Handa <handa@gnu.org>
3812 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3813 here, but just check the validity of glyphs in the glyph-string.
3815 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3817 * window.c (Fwindow_parameter, Fset_window_parameter):
3818 Accept any window as argument (Bug#12452).
3820 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3822 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3823 to ns_term_init to avoid memory leak.
3825 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3826 explicit retain/release.
3827 (ns_term_init): Only allow one display. Initialize outerpool and
3830 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3832 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3833 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3834 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3835 the Microsoft problem in a different way, by altering ../nt/config.nt.
3837 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3852 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3853 by lisp.h. This completes removal of setjmp.h inclusion
3854 erroneously announced in the previous commit. (Bug#12446)
3856 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3859 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3860 not defined as a macro. The latter happens on MS-Windows.
3863 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3865 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3866 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3867 Some instances of '#include <setjmp.h>' removed, if the
3868 only reason for the instance was because "lisp.h" was included.
3869 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3870 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3871 and _longjmp with the new symbols. Emacs already uses _setjmp if
3872 available, so this change affects only POSIXish hosts that have
3873 sigsetjmp but not _setjmp, such as some versions of Solaris and
3874 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3875 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3876 (png_load_body) [HAVE_PNG]:
3877 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3878 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3879 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3880 since PNG requires jmp_buf. This is the only exception to the
3881 general rule that we now use sys_setjmp and sys_longjmp.
3882 This exception is OK since this code does not change the signal
3883 mask or longjmp out of a signal handler.
3885 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3887 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3888 Include "syssignal.h", for 'main_thread'.
3890 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3892 Avoid out-of-range marker position (Bug#12426).
3893 * insdel.c (replace_range, replace_range_2):
3894 Adjust markers before overlays, as suggested by comments.
3895 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3896 Remove redundant check before calling offset_intervals.
3898 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3900 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3901 current buffer (Bug#12387).
3903 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3905 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3907 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3909 Use a more backwards-compatible timer format (Bug#12430).
3910 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3911 vector element, not from the 4th, since PSECS is now at the end.
3912 (Fcurrent_idle_time): Doc fix.
3914 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3916 Function to mark objects and remove killed buffers at once.
3917 * alloc.c (discard_killed_buffers): Rename to ...
3918 (mark_discard_killed buffers) ... new name. Add marking
3919 of remaining objects. Fix comment. Adjust users.
3920 (mark_object): Do not touch frame buffer lists here.
3921 * frame.c (delete_frame): Reset frame buffer lists here.
3923 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3925 Better workaround for GNOME bug when --enable-gcc-warnings.
3926 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3927 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3928 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3930 Simplify SIGIO usage (Bug#12408).
3931 The code that dealt with SIGIO was crufty and confusing, e.g., it
3932 played tricks like "#undef SIGIO" but these tricks were not used
3933 consistently. Simplify mostly by not #undeffing standard symbols,
3934 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3935 or not as we please) rather than "defined SIGIO" (standard symbol
3936 that we probably shouldn't #undef).
3937 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3938 Modules that need it can include it.
3939 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3940 * dispextern.h (ignore_sigio): New decl.
3941 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3942 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3943 * emacs.c (shut_down_emacs):
3944 * keyboard.c (kbd_buffer_store_event_hold):
3945 Use ignore_sigio rather than invoking 'signal' directly.
3946 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3948 (FIONREAD, SIGIO): Do not #undef.
3949 (tty_read_avail_input): Use #error rather than a syntax error.
3950 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3951 for I_PIPE, used by SETUP_SLAVE_PTY.
3952 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3953 * sysdep.c (croak): Remove; no longer needed. This bit of
3954 temporary code, with Fred N. Fish's comment that it's temporary,
3955 has been in Emacs since at least 1992!
3956 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3957 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3958 * syssignal.h (croak): Remove decl.
3959 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3960 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3961 now that we're termios-only.
3962 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3963 * term.c (dissociate_if_controlling_tty): Use #error rather than
3966 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3967 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3968 to work around GNOME bug 683906.
3969 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3970 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3971 This works around GCC bug 54561.
3973 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3975 More fixes for 'volatile' and setjmp/longjmp.
3976 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3977 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3978 (png_load_body) [HAVE_PNG]:
3979 (jpeg_load_body) [HAVE_JPEG]:
3980 New function, with most of the old parent function's body.
3981 (png_load) [HAVE_PNG]:
3982 (jpeg_load) [HAVE_JPEG]:
3983 Invoke the new function, to avoid longjmp munging our locals.
3984 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3985 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3986 longjmp is passed 2, as the C standard doesn't guarantee this.
3987 Instead, store the failure code into mgr->failure_code.
3989 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3991 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3992 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3993 (syms_of_keyboard): Remove support for unread-command-char.
3995 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3997 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3998 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3999 violation. (Bug#12426)
4001 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4003 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4005 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4007 * eval.c: Add `inhibit-debugger'.
4008 (Qinhibit_debugger): New symbol.
4009 (call_debugger): Bind it instead of Qdebug_on_error.
4010 (maybe_call_debugger): Test Vinhibit_debugger.
4011 (syms_of_eval): Define inhibit-debugger.
4012 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4013 (syms_of_xdisp): Remove inhibit-debug-on-message.
4015 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4017 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4018 If a nonvolatile local variable is written before a _longjmp to
4019 the frame containing the variable, and is read after the _longjmp,
4020 the value read is indeterminate. Some local variables of type
4021 'struct handler' and 'struct catchtag' are used in this way, so
4022 mark each of their slots as volatile if the slot can be set before
4023 _longjmp and read afterwards.
4024 * lisp.h (struct handler): var and chosen_clause are now volatile.
4025 (struct catchtag): val, next, and pdlcount are now volatile.
4027 * bidi.c (bidi_push_it, bidi_pop_it):
4028 * fns.c (copy_hash_table):
4029 * image.c (define_image_type):
4030 * keyboard.c (kbd_buffer_store_event_hold):
4031 * process.c (Fprocess_send_eof):
4032 * xfaces.c (x_create_gc) [HAVE_NS]:
4033 * xgselect.c (xg_select):
4034 Prefer assignment to memcpy when either will do.
4036 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4037 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4038 time an item is removed. No need to mark this function 'inline';
4039 the compiler knows better than we do.
4041 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4043 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4044 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4045 to change_frame_size (Bug#12388).
4046 (windowDidResize:): Pass YES to updateFrameSize.
4048 * nsterm.h: Add delay parameter to updateFrameSize.
4050 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4052 Discard killed buffers from deleted window and frame objects.
4053 This reduces an amount of references to killed buffers and
4054 helps GC to reclaim them faster.
4055 * alloc.c (discard_killed_buffers): New function.
4056 (mark_object): Use it for deleted windows and frames.
4057 (mark_object): If symbol's value is set up for a killed buffer
4058 or deleted frame, restore its global binding.
4059 * data.c (swap_in_global_binding): Add GC notice.
4060 (swap_in_symval_forwarding): Use convenient set_blv_where.
4061 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4062 * window.h: ... to here.
4064 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4066 Convenient macro to check whether the buffer is live.
4067 * buffer.h (BUFFER_LIVE_P): New macro.
4068 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4069 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4071 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4073 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4074 composition cases (Bug#12364).
4076 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4077 overhang of succeeding glyphs overlapping box cursor.
4079 * w32term.c (x_draw_glyph_string): Likewise.
4081 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4083 Simplify, document, and port floating-point (Bug#12381).
4084 The porting part of this patch fixes bugs on non-IEEE platforms
4085 with frexp, ldexp, logb.
4086 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4088 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4089 support, by removing commented-out code and briefly listing the
4090 C89 functions excluded. The commented-out stuff was confusing
4091 maintenance, e.g., we thought we needed cbrt but it was commented out.
4092 (logb): Remove decl; no longer needed.
4093 (isfinite): New macro, if not already supplied.
4094 (isnan): Don't replace any existing macro.
4095 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4096 are present on all C89 platforms.
4097 (Ffrexp): Do not special-case zero, as frexp does the right thing
4099 (Flogb): Do not use logb, as it doesn't have the desired meaning
4100 on hosts that use non-base-2 floating point. Instead, stick with
4101 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4102 frexp, to avoid getting an unspecified result.
4104 * xdisp.c (Qinhibit_debug_on_message): Now static.
4106 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4108 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4109 NSBezierPath (Bug#12131).
4111 2012-09-10 Chong Yidong <cyd@gnu.org>
4113 * fns.c (Fdelq, Fdelete): Doc fix.
4115 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4117 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4118 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4120 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4122 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4123 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4126 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4128 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4129 left fringe if the window has a left margin. This avoids leaving
4130 traces of the cursor because its leftmost pixel is not drawn over.
4132 * dispnew.c (update_window_line): When the left margin area of a
4133 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4134 that screen line. (Bug#12277)
4136 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4138 Assume C89 or later for math functions (Bug#12381).
4139 This simplifies the code, and makes it a bit smaller and faster,
4140 and (most important) makes it easier to clean up signal handling
4141 since we can stop worring about floating-point exceptions in
4142 library code. That was a problem before C89, but the problem
4143 went away many years ago on all practical Emacs targets.
4144 * data.c, image.c, lread.c, print.c:
4145 Don't include <math.h>; no longer needed.
4146 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4147 might be autoconfigured, as that never happens.
4149 * doprnt.c (DBL_MAX_10_EXP):
4150 * print.c (DBL_DIG):
4151 Remove. C89 or later always defines these.
4152 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4153 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4154 (arith_error, domain_error, domain_error2):
4155 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4156 no longer needed -- we simply return what C returns. All uses removed.
4157 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4159 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4160 Remove. All uses expanded, as these macros are no longer used
4161 more than once and are now more trouble than they're worth.
4162 (Ftan): Use tan, not sin / cos.
4163 (Flogb): Assume C89 frexp.
4164 (fmod_float): Assume C89 fmod.
4165 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4166 (init_floatfns): Remove. All uses removed.
4168 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4170 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4171 compositeToPoint for OSX < 10.6 (Bug#12390).
4173 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4175 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4176 This produces more-accurate results.
4178 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4180 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4181 changes (Bug#12088).
4183 2012-09-08 Chong Yidong <cyd@gnu.org>
4185 * syntax.c (Fstring_to_syntax): Doc fix.
4187 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4189 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4190 in the internal border.
4191 (x_set_window_size): Remove static variables and their usage.
4192 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4193 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4194 Remove fringe/internal border adjustment (Bug#11052).
4195 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4196 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4197 (ns_fix_rect_ibw): Remove.
4198 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4199 (ns_dumpglyphs_box_or_relief): Ditto.
4200 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4202 (ns_dumpglyphs_image): Ditto.
4203 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4205 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4206 their usage. Add fringe_extended_p and its use as in other terms.
4207 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4208 scroll bar was removed.
4209 (updateFrameSize): New function.
4210 (windowDidResize): Move code to updateFrameSize and call it.
4212 * nsterm.h (EmacsView): Add updateFrameSize.
4214 2012-09-07 Chong Yidong <cyd@gnu.org>
4216 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4218 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4220 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4222 More signal-handler cleanup (Bug#12327).
4223 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4224 Problem introduced when merging patches. Noted by Eli Zaretskii in
4225 <http://bugs.gnu.org/12327#67>.
4226 * floatfns.c: Comment fix.
4227 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4228 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4229 and anyway the declaration is harmless even if SIGDANGER is not defined.
4230 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4231 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4232 source files not surprisingly expected syssignal.h to define, or
4233 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4234 Include <sys/ioctl.h>, for FIONREAD.
4235 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4236 This eliminates a problem whereby other files mysteriously had
4237 to include "syssignal.h" before including "systty.h" if they
4238 wanted to use "#ifdef SIGIO".
4240 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4242 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4244 * w32.c (sigemptyset): Empty the set.
4245 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4247 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4249 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4251 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4252 (mark_object): Likewise for frame objects.
4254 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4256 * syssignal.h (handle_on_main_thread): Always declare,
4257 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4258 This ports to platforms without HAVE_PTHREAD.
4260 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4262 Signal-handler cleanup (Bug#12327).
4263 Emacs's signal handlers were written in the old 4.2BSD style with
4264 sigblock and sigmask and so forth, and this led to some
4265 inefficiencies and confusion. Rewrite these to use
4266 pthread_sigmask etc. without copying signal sets around. Also,
4267 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4268 'signal', and instead use functions that do not attempt to take
4269 over the system name space. This patch causes Emacs's text
4270 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4271 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4272 Do not include <signal.h> or "syssignal.h", as these
4273 modules do not use signals.
4274 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4275 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4276 Do not include <signal.h>, as "syssignal.h" does that for us now.
4277 * atimer.c (sigmask_atimers): New function.
4278 (block_atimers, unblock_atimers): New functions,
4279 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4281 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4282 no longer needed here.
4283 * emacs.c (main): Inspect existing signal handler with sigaction,
4284 so that there's no need to block and unblock SIGHUP.
4285 * sysdep.c (struct save_signal): New member 'action', replacing
4286 old member 'handler'.
4287 (save_signal_handlers, restore_signal_handlers):
4288 Use sigaction instead of 'signal' to save and restore.
4289 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4290 New function. All users of 'signal' modified to use set_sighandler
4291 if they're writeonly, and to use sys_signal if they're read+write.
4292 (emacs_sigaction_init, forwarded_signal): New functions.
4293 (sys_signal): Remove. All uses replaced by calls to sigaction
4294 and emacs_sigaction_init, or by direct calls to 'signal'.
4295 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4296 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4297 all uses replaced by pthread_sigmask etc. calls.
4298 * syssignal.h: Include <signal.h>.
4299 (emacs_sigaction_init, forwarded_signal): New decls.
4300 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4301 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4302 (sigmask, sys_sigmask): Remove; no longer needed.
4303 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4304 (sigblock, sigunblock, sigfree):
4305 (sigsetmask) [!defined sigsetmask]:
4306 Remove. All uses replaced by pthread_sigmask.
4307 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4308 no longer need to be replaced, and its typical old uses
4309 are now done via emacs_sigaction_init and sigaction.
4310 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4311 (sys_sigdel): Remove; unused.
4312 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4314 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4316 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4317 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4319 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4321 Explicitly mark buffer_defaults and buffer_local_symbols.
4322 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4323 mark_local_symbols here.
4324 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4325 since special buffers aren't marked here any more.
4326 (allocate_buffer): Chain new buffer with all_buffers here...
4327 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4329 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4330 (syms_of_buffer): Remove staticpro of the above.
4331 (init_buffer_once): Set names for buffer_defaults and
4332 buffer_local_symbols.
4334 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4336 Use bool for booleans in font-related modules.
4337 * font.c (font_intern_prop, font_style_to_value)
4338 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4339 (generate_otf_features, font_check_otf_features, font_check_otf)
4340 (font_match_p, font_list_entities, font_at):
4341 * fontset.c (fontset_id_valid_p, reorder_font_vector
4342 (fontset_find_font, Fset_fontset_font)
4343 (face_suitable_for_char_p) [0]:
4344 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4345 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4346 (m17n_flt_initialized, ftfont_shape_by_flt):
4347 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4348 * nsfont.m (nsfont_draw):
4349 * w32font.c (w32font_draw):
4350 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4351 Use bool for booleans.
4352 * font.h: Adjust to above API changes.
4353 (struct font, struct font_driver, struct font_driver_list):
4354 Use bool for booleans.
4355 (struct font): Remove useless member encoding_type.
4357 * fontset.c, xftfont.c: Omit unnecessary static decls.
4359 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4361 * alloc.c (mark_object): Revert window marking code
4362 since it's unsafe for the Fset_window_configuration.
4364 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4366 Fix race conditions with signal handlers and errno (Bug#12327).
4367 Be more systematic about preserving errno whenever a signal
4368 handler returns, even if it's not in the main thread. Do this by
4369 renaming signal handlers to distinguish between signal delivery
4370 and signal handling. All uses changed.
4371 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4372 * data.c (deliver_arith_signal): Rename from arith_error.
4373 * dispnew.c (deliver_window_change_signal): Rename from
4374 window_change_signal.
4375 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4376 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4377 * keyboard.c (deliver_input_available_signal): Rename from
4378 input_available_signal.
4379 (deliver_user_signal): Rename from handle_user_signal.
4380 (deliver_interrupt_signal): Rename from interrupt_signal.
4381 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4382 (deliver_child_signal): Rename from sigchld_handler.
4383 * atimer.c (handle_alarm_signal):
4384 * data.c (handle_arith_signal):
4385 * dispnew.c (handle_window_change_signal):
4386 * emacs.c (handle_fatal_signal, handle_danger_signal):
4387 * keyboard.c (handle_input_available_signal):
4388 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4389 * process.c (handle_pipe_signal, handle_child_signal):
4390 New functions, with the actual signal-handling code taken from the
4391 original respective signal handlers, sans the sporadic attempts to
4392 preserve errno, since that's now done by handle_on_main_thread.
4393 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4394 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4395 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4397 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4398 Move initialization of main_thread to sysdep.c's init_signals.
4399 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4400 our usage, and simplifies the mainline code.
4401 (record_child_status_change): New static function, as a helper
4402 for handle_child_signal, and with most of the old child handler's
4404 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4405 (handle_child_signal): Use the above.
4406 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4407 Moved here from emacs.c.
4408 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4409 code moved here from emacs.c's main function.
4410 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4411 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4412 This lets callers save and restore errno properly.
4414 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4416 Remove redundant or unused things here and there.
4417 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4418 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4419 * editfns.c (Fcompare_buffer_substrings): Likewise.
4420 * frame.h (struct terminal, struct font_driver_list):
4421 Remove redundant declarations.
4422 * window.h (Qleft, Qright): Likewise.
4424 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4426 Do not mark objects from deleted buffers, windows and frames.
4427 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4428 (mark_object): Likewise for windows and frames.
4430 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4432 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4433 buffer_defaults and buffer_local_symbols as valid objects.
4434 Return special value to denote them.
4436 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4438 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4439 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4440 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4441 (file_name_absolute_p, Fsubstitute_in_file_name):
4442 (check_executable, check_writable, Ffile_accessible_directory_p)
4443 (Fset_file_selinux_context, Fdefault_file_modes)
4444 (Finsert_file_contents, choose_write_coding_system)
4445 (Fwrite_region, build_annotations, a_write, e_write)
4447 * filelock.c (boot_time_initialized, get_boot_time)
4448 (get_boot_time_1, lock_file_1, within_one_second):
4449 * floatfns.c (in_float):
4450 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4451 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4452 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4453 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4454 * window.c (compare_window_configurations):
4455 Use bool for booleans.
4456 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4457 (Fdefault_file_modes): Now mode_t, not int, for modes.
4458 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4459 (internal_delete_file): Now returns void, not a (boolean) int,
4460 since nobody was looking at the return value.
4461 * lisp.h, window.h: Adjust to above API changes.
4463 * xdisp.c (set_message): Simplify and reindent last change.
4465 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4467 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4469 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4471 * eval.c (call_debugger): Make the function non-static so that we
4472 can call it from set_message.
4474 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4475 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4477 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4479 Give more-useful info on a fatal error (Bug#12328).
4480 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4481 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4482 of doing the work ourselves.
4483 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4484 do most of the work.
4485 (fatal_error_backtrace): New function, taken from the guts
4486 of the old fatal_error_signal, but with a new option to output
4488 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4489 info about the signal than just its number.
4490 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4491 * sysdep.c: Include <execinfo.h>
4492 (emacs_backtrace): New function, taken partly from the previous
4493 code of the 'die' function.
4494 (emacs_abort): Call fatal_error_backtrace rather than abort.
4496 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4498 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4499 eager (load-time) macro-expansion.
4500 * lisp.mk (lisp): Add macroexp.
4502 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4504 Simplify redefinition of 'abort' (Bug#12316).
4505 Do not try to redefine the 'abort' function. Instead, redo
4506 the code so that it calls 'emacs_abort' rather than 'abort'.
4507 This removes the need for the NO_ABORT configure-time macro
4508 and makes it easier to change the abort code to do a backtrace.
4509 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4510 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4511 Remove; sysdep.c's emacs_abort now takes its place.
4512 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4513 'abort' changed to use 'emacs_abort'.
4514 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4515 (abort) [!defined abort]: Rename to ...
4516 (emacs_abort): ... new name.
4517 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4518 the place of the old 'abort' in emacs.c.
4519 * w32.c, w32fns.c (abort): Do not #undef.
4520 * w32.c (emacs_abort): Rename from w32_abort.
4522 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4524 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4525 offsets[j].dv, since the y axis of the screen coordinates points
4526 down, while the y axis of the font definition coordinates points
4527 up. This fixes display of Arabic diacritics such as KASRA and
4528 KASRATAN. (Bug#11860)
4530 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4532 Be more systematic about _setjmp vs setjmp.
4533 * alloc.c (test_setjmp, mark_stack):
4534 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4535 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4536 (png_load, my_error_exit, jpeg_load):
4537 * process.c (send_process_trap, send_process):
4538 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4539 The underscored versions are up to 30x faster on some hosts.
4540 Formerly, the code used setjmp+longjmp sometimes and
4541 _setjmp+_longjmp at other times, with no particular reason to
4542 prefer setjmp+longjmp.
4544 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4546 Fix minor problem found by static checking.
4547 * buffer.c (Fdelete_all_overlays): Return nil.
4549 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4551 * buffer.c (Fdelete_all_overlays): New function.
4553 2012-09-03 Chong Yidong <cyd@gnu.org>
4555 * gtkutil.c: Add extern decl for Qxft.
4557 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4559 * emacs.c, eval.c: Use bool for boolean.
4560 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4561 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4562 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4563 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4564 (main, decode_env_path, Fdaemon_initialized):
4565 * eval.c (call_debugger, Finteractive_p, interactive_p):

4583 REDISPLAYING_P when unwinding, instead of saving its previous,
4584 always-false value and then restoring it.
4586 Clean up some extern decls.
4587 Mostly, this hoists extern decls out of .c files and into .h files.
4588 That way, we're more likely to catch errors if the interfaces change.

4674 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4675 more than one grapheme cluster passed to the shaper: compute the
4676 offset adjustment values separately for each cluster. (Bug#11860)
4678 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4679 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4680 about implicit conversions from integer to pointer.
4682 2012-09-01 Daniel Colascione <dancol@dancol.org>
4684 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

4738 window system declarations.
4740 * frame.h: Move common functions here: set_frame_menubar,
4741 x_set_window_size, x_sync, x_get_focus_frame,
4742 x_set_mouse_position, x_set_mouse_pixel_position,
4743 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4804 * lread.c (init_lread): For out-of-tree builds, only add the
4805 source directory's site-lisp dir to the load-path if it exists,
4806 consistent with in-tree builds. (Bug#12302)
4808 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

4829 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4830 Add window_closed and button_values. Add void as return value for
4831 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4832 Add process_dialog as new member.

5015 (syms_of_data): Do not define 'interval'.
5016 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5017 * window.h (decode_valid_window):
5020 * character.c, charset.c, chartab.c: Use bool for booleans.
5021 * character.c (lisp_string_width, string_count_byte8)
5022 (string_escape_byte8):
5023 * charset.c (charset_map_loaded, load_charset_map, read_hex):
5024 (load_charset_map_from_file, map_charset_chars)
5025 (Fdefine_charset_internal, define_charset_internal)
5026 (Fdeclare_equiv_charset, find_charsets_in_text)
5027 (Ffind_charset_region, char_charset, Fiso_charset):
5028 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
5029 (sub_char_table_set, sub_char_table_set_range)
5030 (char_table_set_range, optimize_sub_char_table)
5031 (map_sub_char_table):
5032 Use bool for boolean.
5033 * character.c (str_to_unibyte): Omit last boolean argument; it was
5034 always 0. All callers changed.
5035 * character.h, charset.h: Adjust to match previous changes.
5036 * character.h (char_printable_p): Remove decl of nonexistent function.
5037 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5038 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5039 are all boolean, so make them single-bit bitfields.
5041 * lisp.h (ASET): Remove attempt to detect side effects.
5042 It was meant to be temporary and it often doesn't work,
5043 because when IDX has side effects the behavior of IDX==IDX
5044 is undefined. See Stefan Monnier in
5045 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5047 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5049 * lisp.h (functionp): New function (extracted from Ffunctionp).
5050 (FUNCTIONP): Use it.
5051 * eval.c (Ffunctionp): Use it.
5053 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5055 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5056 as that's faster and simpler than static storage. Don't bother
5057 with the g_main_context_query overhead if g_main_context_pending
5058 says no events are pending.
5059 (gfds, gfds_size): Remove these static vars.
5060 (xgselect_initialize): Remove; no longer needed.
5061 All uses and decls removed.
5063 * emacs.c (fatal_error_signal_hook): Remove.
5064 All uses removed. This leftover from old code was always 0.
5066 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5067 * casefiddle.c (casify_object, casify_region):
5068 * casetab.c (set_case_table):
5069 * category.c, category.h (word_boundary_p):
5070 * category.h (CHAR_HAS_CATEGORY):
5071 Use bool for booleans, instead of int.
5073 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5075 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5077 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5079 On assertion failure, print backtrace if available.
5080 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5081 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5082 * Makefile.in (LIB_EXECINFO): New macro.
5085 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5086 * bytecode.c (exec_byte_code):
5087 * callint.c (check_mark, Fcall_interactively):
5088 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5089 (getenv_internal, sync_process_alive, call_process_exited):
5090 * lisp.h (USE_SAFE_ALLOCA):
5091 Use bool for booleans, instead of int.
5092 * lisp.h, process.h: Adjust prototypes to match above changes.
5093 * callint.c (Fcall_interactively): Don't assume the mark's
5094 offset fits in 'int'.
5096 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5098 * buffer.c, buffer.h: Use bool for boolean.
5099 * buffer.c (reset_buffer_local_variables)
5100 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5101 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5102 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5103 (overlay_touches_p, overlay_strings, Foverlay_put)
5104 (report_overlay_modification, call_overlay_mod_hooks):
5105 (mmap_enlarge, mmap_set_vars):
5106 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5107 Use bool for booleans, instead of int.
5108 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5109 since the 1-or-0 return value is always ignored anyway.
5110 (mmap_initialized_p):
5111 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5112 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5114 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5116 * bidi.c: Use bool for boolean.
5117 This is a bit more readable, and makes the text segment of bidi.o
5118 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5119 Presumably it's faster too.
5120 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5122 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5123 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5124 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5125 (bidi_explicit_dir_char, bidi_level_of_next_char)
5126 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5127 Use bool for booleans, instead of int.
5128 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5129 (bidi_unshelve_cache): Adjust decls to match code.
5131 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5133 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5136 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5138 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5139 * atimer.h: Include <stdbool.h>.
5141 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5143 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5144 compile time tests instead of run time tests on systems that do
5146 (FRAME_MAC_P): Remove leftover from deleted code.
5147 * frame.c (syms_of_frame): Remove leftover from deleted code.
5149 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5151 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5153 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5155 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5156 Otherwise, the compiler complains about (A?B:C) where B is void
5157 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5158 (fontset_add): Return void, for FONTSET_ADD.
5160 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5162 * alloc.c: Use bool for booleans.
5163 (gc_in_progress, abort_on_gc)
5164 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5165 (dont_register_blocks) [GC_MALLOC_CHECK]:
5166 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5167 (check_string_bytes, make_specified_string, memory_full)
5168 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5169 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5170 (mark_stack, valid_pointer_p, make_pure_string)
5171 (Fgarbage_collect, survives_gc_p, gc_sweep):
5172 Use bool for booleans, instead of int.
5173 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5174 Remove unused local.
5175 * alloc.c (PURE_POINTER_P):
5176 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5177 * editfns.c (Fformat):
5178 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5180 * fns.c (sweep_weak_table):
5181 * lisp.h (suppress_checking, push_message, survives_gc_p)
5182 (make_pure_string, gc_in_progress, abort_on_gc):
5183 * lread.c (readchar, read1):
5184 * print.c (Fprin1_to_string):
5185 * xdisp.c (push_message):
5186 Use bool for booleans affected directly or indirectly by
5189 Make recently-introduced setters macros.
5190 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5191 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5192 (set_fontset_default, set_fontset_fallback): Rename from their
5193 upper-case counterparts, and make them functions rather than macros.
5194 This is more consistent with the other recently-introduced setters.
5195 These don't need to be inline, since they're local.
5197 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5199 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5200 the loop (Bug#12247).
5202 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5204 * lisp.h (vcopy): Use memcpy rather than our own loop.
5205 This fixes a performance regression introduced by the recent
5206 addition of vcopy. This means 'vcopy' will need to be modified
5207 for a copying collector, but that's OK. Also, tighten the
5208 checking in the assertion.
5210 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5212 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5213 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5214 non-base glyph for the width of the base character, according to
5215 what x_draw_composite_glyph_string_foreground expects.
5216 Generate WADJUST value according to composition_gstring_width's
5217 expectations, to produce correct width of the composed character.
5218 Reverse the sign of the DU offset produced by ScriptPlace.
5220 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5222 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5224 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5226 Avoid direct writes to contents member of struct Lisp_Vector.
5227 * lisp.h (vcopy): New function to copy data into vector.
5228 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5229 * fns.c (Ffillarray): Use ASET.
5230 * keyboard.c (timer_check_2): Use AREF and ASET.
5231 (append_tool_bar_item, Frecent_keys): Use vcopy.
5232 * lread.c (read_vector): Use ASET.
5233 * msdos.c (Frecent_doskeys): Use vcopy.
5234 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5235 (Finternal_merge_in_global_face): Use ASET and vcopy.
5236 * xfont.c (xfont_list_pattern): Likewise.
5238 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5240 * window.c (Fwindow_point): For the selected window always return
5241 the position of its buffer's point.
5242 (Fset_window_point): For the selected window always go in its
5243 buffer to the specified position.
5245 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5247 Setter macros for fontsets.
5248 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5249 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5250 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5253 2012-08-20 Glenn Morris <rgm@gnu.org>
5255 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5256 Don't assume that `ln -f' works.
5258 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5260 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5261 and later about non-assignments with no effect. See discussion at
5262 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5265 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5267 Inline setter functions for Lisp_Objects slots of struct specbinding.
5268 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5271 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5273 * window.c (select_window): Always make selected window's buffer
5276 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5278 Use AREF and ASET for docstrings of category tables.
5279 * category.h (CATEGORY_DOCSTRING): Use AREF.
5280 (SET_CATEGORY_DOCSTRING): Use ASET.
5281 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5283 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5285 Inline setter functions for hash table members.
5286 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5287 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5288 (set_hash_key_and_value, set_hash_index, set_hash_next)
5289 (set_hash_hash): New functions.
5290 * charset.c, fns.c: Adjust users.
5292 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5294 Inline getter and setter functions for per-buffer values.
5295 * buffer.h (per_buffer_default, set_per_buffer_default)
5296 (per_buffer_value, set_per_buffer_value): New functions.
5297 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5298 * buffer.c, data.c: Adjust users.
5300 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5302 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5304 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5306 Rely on <config.h> + <unistd.h> to declare 'environ',
5307 as gnulib does this if the system doesn't.
5308 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5309 Remove declaration. MS-Windows declares it on stdlib.h which is
5310 included by conf_post.h.
5311 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5312 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5313 * vm-limit.c: Include <unistd.h>, for 'environ'.
5315 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5316 (start_of_data): Remove decl; mem-limits.h provides it.
5318 * xdisp.c (handle_invisible_prop): Make it a bit faster
5319 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5321 2012-08-19 Chong Yidong <cyd@gnu.org>
5323 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5326 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5328 * .gdbinit: Use call instead of set when calling a function in the
5331 * data.c (set_internal): Don't use set_blv_found.
5332 (Fkill_local_variable): Likewise.
5334 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5336 * nsfont.m (ns_ascii_average_width): Ensure the string
5337 ascii_printable is initialized with a null-terminated character
5338 array. Otherwise, it can contain undesired extra characters.
5340 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5342 port new setting code to Sun C 5.8 2005/10/13
5343 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5344 Return void, not Lisp_Object. Otherwise, the compiler
5345 complains about (A?B:C) where B is void and C is Lisp_Object
5346 when compiling CHAR_TABLE_SET, due to the recent change to
5347 the API of sub_char_table_set_contents.
5349 2012-08-18 Chong Yidong <cyd@gnu.org>
5351 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5352 for the string case (Bug#3874).
5354 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5356 * buffer.h (BSET): Remove (Bug#12215).

5426 New setter functions.
5428 * termhooks.h (TSET): Remove (Bug#12215).

5430 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
5431 (TERMHOOKS_INLINE): New macro.
5432 (tset_charset_list, tset_selection_alist): New setter functions.
5433 * terminal.c (TERMHOOKS_INLINE):
5434 Define to EXTERN_INLINE, so that the corresponding functions
5435 are compiled into code.
5436 (tset_param_alist): New setter function.
5438 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

6184 value of EMACSLOADPATH, as it is no longer needed.
6185 (check_windows_init_file): Now external, not static.

6191 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6236 * alloc.c (record_xmalloc): New function.
6237 * lisp.h (record_xmalloc): New decl.
6238 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6239 more like a function. This is because the pointer cast is not
6240 needed. All uses changed.
6241 * print.c (print_string, print_error_message): Avoid length recalc.
6243 Improve fix for macroexp crash with debugging (Bug#12118).
6244 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6245 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6246 not supposed to be invoked from the garbage collector.

6248 (gc_aset): New function, which is like ASET but can be
6249 used in the garbage collector.

6278 with addition of handling of symlinks and support for 'lstat'.
6279 If possible, get file's attributes and security information by
6280 handle, not by name. Produce S_IFLNK bit for symlinks, when
6281 called from 'lstat'.
6282 (stat, lstat): New functions, call 'stat_worker'.
6283 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6284 symlinks when the underlying filesystem supports them.
6286 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6288 Fix macroexp crash on Windows with debugging (Bug#12118).
6289 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6290 checking subscripts; problem introduced with the recent
6291 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6292 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6293 since it's used in non-static inline functions now.
6295 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

6787 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6788 arms of an 'if', not using conditional expressions; otherwise GDB
6789 complains about the types in the unevaluated arm when the argument
6790 is an integer literal.
6791 (xgetint): Simplify expression.
6792 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6793 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6794 Zaretskii in <http://bugs.gnu.org/12036#13>.
6795 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6796 needed now that we have gdb_make_enums_visible.
6797 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6798 (enum enum_USE_LSB_TAG):
6799 New enum types, packaging up enums that need to be exported to GDB.
6801 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

6817 * xdisp.c (syms_of_xdisp): Likewise.
6818 * xfns.c (syms_of_xfns): Likewise.
6820 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6822 Fast save_excursion_save and save_excursion_restore.
6823 * lisp.h (struct Lisp_Excursion): New data type.
6824 (PVEC_EXCURSION): New pseudovector type.
6825 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6826 to deal with it. Adjust comments.
6827 (init_marker, attach_marker): New prototype.
6828 (unchain_marker): Adjust prototype.

6837 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6839 Fix export of symbols to GDB (Bug#12036).
6840 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6841 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6842 emacs.c, as this is a more-suitable home. Had this been done earlier
6843 the fix for 12036 would have avoided some of the problems noted in
6844 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6845 would have been more obvious.
6846 * emacs.c: Do not include <verify.h>; no longer needed.
6847 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6848 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6849 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6850 Remove; now done in lisp.h.
6851 * lisp.h (PUBLISH_TO_GDB): New macro.

6853 (DATA_SEG_BITS): Use it.
6854 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6855 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6856 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6857 not be usable in #if. This simplifies things.
6859 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6861 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6863 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6865 Simplify export of symbols to GDB (Bug#12036).
6866 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6867 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6868 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6869 Adjust to changes in lisp.h and emacs.c, by using
6870 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6871 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6872 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6873 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6874 instead of gdb_valbits.
6875 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6876 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6877 instead of gdb_array_mark_flag.
6878 (xboolvector): Get size from $->size, not $->header.size.
6879 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6880 (xreload, hook-run, hookpost-run): Remove.
6881 * emacs.c: Include <verify.h>.
6882 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6883 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6885 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6886 (gdb_USE_LSB_TAG): New enum constants.
6887 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6888 Also define these as enum constants, so they're visible to GDB.
6889 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6890 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6891 as constants, so they're visible to GDB.
6892 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6893 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6894 Now enum constants, not macros, so they're visible to GDB.
6895 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6896 more convenient now. All uses changed.
6897 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6898 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6900 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6907 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6908 add argument, tune behavior, and adjust all callers.
6910 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6912 Use typedef for EMACS_INT, EMACS_UINT.
6913 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6914 than macros. This simplifies debugging in the usual case, since
6915 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6916 and it allows expressions involving EMACS_INT casts.
6917 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6919 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6927 that FOCUS-FRAME can be omitted.
6929 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6931 Adjust buffer text indirection counters at the end of Fkill_buffer.
6932 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6933 buffer is definitely dead. This should really fix an issue reported
6934 by Christoph Scholtes again. (Bug#12007).
6935 (init_buffer_once): Initialize indirection counters of
6936 buffer_defaults and buffer_local_symbols (for sanity and safety).
6938 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6940 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6941 and continuation glyphs on tooltip frames, leave them at zero.

6969 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6971 Swap buffer text indirection counters in Fbuffer_swap_text.
6972 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6973 This avoids crash reported by Christoph Scholtes at
6974 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6976 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6978 * nsmenu.m (Popdown_data): New struct.

6983 and autorelease them. Also autorelease img and matrix (Bug#12005).
6984 (dealloc): Remove (Bug#12005).

7001 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7003 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7004 as it's limited by the amount of memory, not by INT_MAX.
7006 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7008 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7009 in special-event-map. See the discussion at

7069 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
7070 Adjust users accordingly.
7071 * font.h (font_open_by_name): Adjust prototype.

7090 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
7091 'for_each_per_buffer_object_at'.
7092 All uses changed. It's better to use upper-case for macros that
7093 cannot be implemented as functions, to give the reader a clue
7094 that they're special.
7096 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>

7139 * intervals.c (merge_interval_right, merge_interval_left):
7140 Do not zero out this interval if it is absorbed by its children,
7141 as this interval's total length doesn't change in that case. See
7142 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
7144 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
7146 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
7147 when invoking (make-bool-vector N t) and N is a positive

7151 * alloc.c (bool_header_size): New constant.
7152 (header_size, word_size): Move earlier, as they're now used earlier.

7155 padding before the data member of a bool vector.
7156 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
7157 than doing the check by hand with an abort ().
7159 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7161 * eval.c (Fdefvar): Don't check constants since we only set the var if
7162 it's not yet defined anyway (bug#11904).
7164 * lisp.h (last_undo_boundary): Declare new var.
7165 * keyboard.c (command_loop_1): Set it.
7166 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
7167 were auto-added by the command loop (bug#11774).
7169 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
7171 * w32font.c (Qsymbol): Remove local definition.

7670 Move CLASH_DETECTION to configure.
7672 * s/gnu.h: Remove file, which is now empty.
7674 * s/gnu.h, s/gnu-linux.h:
7675 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
7677 2012-07-11 John Wiegley <johnw@newartisans.com>
7679 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
7680 function attribute, so we only use it if it exists in the
7683 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
7685 Avoid call to strlen in fast_c_string_match_ignore_case.
7686 * search.c (fast_c_string_match_ignore_case): Change to use
7687 length argument. Adjust users accordingly.
7688 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
7690 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

7731 Remove "#define unix" that is no longer needed (Bug#11905).
7732 * s/aix4-2.h (unix): Remove; no longer needed.
7734 EMACS_TIME simplification (Bug#11875).
7735 This replaces macros (which typically do not work in GDB)
7736 with functions, typedefs and enums, making the code easier to debug.
7737 The functional style also makes code easier to read and maintain.
7738 * systime.h: Include <sys/time.h> on all hosts, not just if
7739 WINDOWSNT, since 'struct timeval' is needed in general.
7740 (EMACS_TIME): Now a typedef, not a macro.
7741 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
7743 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

7746 (EMACS_TIME_LE): Now functions, not macros.
7747 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
7748 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
7749 which are not functions. All uses rewritten to use:
7750 (make_emacs_time): New function.
7751 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
7752 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
7753 not functions. All uses rewritten to use the following, respectively:
7754 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
7755 (add_emacs_time, sub_emacs_time): New functions.
7756 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
7757 * fileio.c (Fcopy_file):
7758 * xterm.c (XTflash): Get the current time closer to when it's used.
7759 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

7767 * gtkutil.c (get_utf8_string):
7769 * nsmenu.m (ns_update_menubar):
7770 * regex.c (regerror):
7771 Prefer memcpy to strncpy and strncat when either will do.
7772 * fileio.c (Fsubstitute_in_file_name):
7773 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
7774 (menu_separator_name_p):
7775 * nsmenu.m (ns_update_menubar):
7776 Prefer memcmp to strncmp when either will do.
7777 * nsterm.m: Include <ftoastr.h>.
7779 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7780 Prefer snprintf to strncpy.
7781 * nsterm.m (ns_term_init):
7782 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7783 * nsterm.m (ns_term_init):
7784 Avoid the need for strncpy, by using build_string or
7785 make_unibyte_string directly. Use dtoastr, not snprintf.
7786 * process.c (Fmake_network_process): Diagnose service names that
7787 are too long, rather than silently truncating them or creating
7788 non-null-terminated names.
7789 (Fnetwork_interface_info): Likewise, for interface names.
7790 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7791 Prefer sprintf to strncat.
7792 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
7793 Prefer vsnprintf to vsprintf + strncpy.
7795 2012-07-10 Glenn Morris <rgm@gnu.org>
7797 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
7798 Clarify fallback case.
7800 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7802 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
7803 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
7804 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7805 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7806 where argument type is known to be a Lisp_Cons.
7808 2012-07-10 Tom Tromey <tromey@redhat.com>
7810 * bytecode.c (BYTE_CODE_THREADED): New macro.
7811 (BYTE_CODES): New macro. Replaces all old byte-code defines.

7818 Optimize pure C strings initialization.
7819 * lisp.h (make_pure_string): Fix prototype.
7820 (build_pure_c_string): New function, defined as static inline. This
7821 provides a better opportunity to optimize away calls to strlen when
7822 the function is called with compile-time constant argument.
7823 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7824 argument, adjust users accordingly. Use build_pure_c_string where
7826 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7827 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7828 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7830 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7832 Avoid calls to strlen in miscellaneous functions.
7833 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7834 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7835 * lread.c (openp): Likewise.
7837 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7839 Avoid calls to strlen in path processing functions.
7840 * fileio.c (file_name_as_directory): Add comment. Change to add
7841 srclen argument and return the length of result. Adjust users
7843 (directory_file_name): Fix comment. Change to add srclen argument,
7844 swap 1st and 2nd arguments to obey the common convention.
7845 Adjust users accordingly.
7846 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7848 2012-07-10 Glenn Morris <rgm@gnu.org>
7850 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

7855 * s/gnu.h (DATA_START): Move definitions to configure.
7857 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7858 We include usg5-4-common.h, which defines them both.
7860 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7861 O_RDONLY already includes it).
7863 Stop ns builds setting the EMACSLOADPATH environment variable.
7864 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7865 Now it does not set EMACSLOADPATH, just returns the load-path string.
7866 * nsterm.h: Update accordingly.
7867 * lread.c [HAVE_NS]: Include nsterm.h.
7868 (init_lread) [HAVE_NS]: Use ns_load_path.
7869 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7871 2012-07-09 Glenn Morris <rgm@gnu.org>
7873 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7874 since the included bsd-common.h does so.
7876 Stop ns builds setting the EMACSPATH environment variable.
7877 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7878 (ns_init_paths): Do not set EMACSPATH.
7879 * nsterm.h (ns_exec_path): Add it.
7880 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7883 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7885 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7887 * process.c (wait_reading_process_output): 'waitchannels' was unset
7888 when read_kbd || !NILP (wait_for_cell); fix this.
7890 Add GCC-style 'const' attribute to functions that can use it.
7891 * character.h (char_resolve_modifier_mask):
7892 * keyboard.h (make_ctrl_char):
7893 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
7894 (init_character_once, next_almost_prime, init_fns, init_image)
7895 (flush_pending_output, init_sound):
7896 * mem-limits.h (start_of_data):

7900 Declare the dummy function with ATTRIBUTE_CONST.
7901 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7902 Add decls with ATTRIBUTE_CONST.
7904 Minor improvements to make_formatted_string.
7905 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7906 where int is good enough, as vsprintf returns an int.
7907 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7909 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7911 Use make_formatted_string to avoid double length calculation.
7912 * lisp.h (make_formatted_string): New prototype.

7919 (x_report_frame_params): Likewise.
7920 * image.c (gs_load): Likewise.
7921 * minibuf.c (get_minibuffer): Likewise.

7936 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7938 Move marker debugging code under MARKER_DEBUG.
7939 * marker.c (MARKER_DEBUG): Move marker debugging code under
7940 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7941 for bootstrap with --enable-checking (~3x slowdown reported
7942 by Juanma Barranquero <lekktu@gmail.com>).
7943 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7945 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7947 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7948 See <http://bugs.gnu.org/11825#29>.
7950 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7952 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7953 has no font, use the frame's font. (Bug#11813)
7954 (display_line): Add commentary about displaying truncation glyphs
7956 (produce_special_glyphs): Move here from term.c.
7958 * term.c (produce_special_glyphs): Move to xdisp.c.
7960 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7963 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7965 * xdisp.c (display_line): Avoid warning about implicit declaration
7968 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7970 * lisp.h: Remove empty conditional.
7972 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7974 * lread.c (load_path_check): Now static.
7976 Fix some minor --with-ns problems found by static checking.
7977 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7978 (x_set_font) [!HAVE_X_WINDOWS]:
7979 * image.c (xpm_load_image) [HAVE_NS]:
7980 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7981 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7982 Remove unused local.
7983 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7984 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.

7986 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7987 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7988 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7989 Fix pointer signedness problem.
7990 * xfaces.c (FRAME_X_FONT_TABLE):
7991 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7993 2012-07-07 Glenn Morris <rgm@gnu.org>
7995 * lread.c (load_path_check): New function, split from init_lread.
7996 (init_lread): Reorganize. Motivation:
7997 If EMACSLOADPATH is set, check/warn about that rather than the
7998 defaults, which we are not going to use. Hence we can remove
7999 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8000 Don't warn if site-lisp directories are missing.
8001 If not installed, start from a blank load-path, since
8002 PATH_LOADSEARCH refers to the eventual installation directories.
8004 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8006 Support truncation and continuation glyphs on GUI frames, when
8007 fringes are disabled. (Bug#11832)
8008 * xdisp.c (init_iterator): Get dimensions of truncation and
8009 continuation glyphs even if on GUI frames.
8010 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8011 or both, are absent.
8012 (start_display, move_it_in_display_line_to): Handle the case of a
8013 GUI frame without a fringe to display continuation or truncation
8015 (insert_left_trunc_glyphs): Support GUI frames: make sure
8016 truncation glyphs overwrite enough glyphs from the current line to
8017 have sufficient space in pixels.
8018 (display_line): Support truncation and continuation glyphs on GUI
8019 frames. If some spare pixels are left on the line after inserting
8020 the truncation glyphs, fill that space with a stretch glyph of a
8021 suitably computed width.
8023 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8024 produce_glyphs, to support GUI sessions.
8026 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8028 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8030 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8032 Do not require float-time's arg to fit in time_t (Bug#11825).
8033 This works better on hosts where time_t is unsigned, and where
8034 float-time is applied to the (negative) difference between two times.
8035 * editfns.c (decode_time_components): Last arg is now double *,
8036 not int *, and means to store all the result as a double, without
8037 worrying about whether the seconds part fits in time_t.
8038 All callers changed.
8039 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8040 All callers changed.
8041 (Ffloat_time): Do not fail merely because the specified time falls
8042 outside of time_t range.
8044 2012-07-07 Glenn Morris <rgm@gnu.org>

8050 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
8052 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8053 Update dependencies.
8055 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8057 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8059 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
8060 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
8061 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8062 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8063 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8064 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8066 * xfont.c (compare_font_names): Redo to omit the need for casts.
8068 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8070 * xfns.c (Fx_change_window_property): Doc fix.
8071 * w32fns.c (Fx_change_window_property): Doc fix.
8073 * w32fns.c (Fx_window_property): Accept the same arguments as the
8074 X Windows version. Doc fix.
8075 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8077 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8078 Eli Zaretskii <eliz@gnu.org>
8080 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8081 Windows-specific code from nt/config.nt moved here.
8082 Obsolete settings removed.
8084 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8086 * process.c: Avoid unnecessary calls to gettime.
8087 (wait_reading_process_output): Don't get the time of day
8088 when gobbling data immediately and not waiting, as there's no need
8089 for it in that case. This removes a FIXME.
8091 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8093 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8094 is defined (Bug#11768).
8096 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8098 Fix marker debugging code.
8099 * marker.c (byte_char_debug_check): Do not perform the check
8100 if buffer is not multibyte.
8101 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8102 Call byte_char_debug_check with correct arguments.
8104 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8106 Compile marker debugging code only if ENABLE_CHECKING is defined.
8107 * marker.c (byte_char_debug_check, count_markers):
8108 Use only if ENABLE_CHECKING is defined.
8109 (byte_debug_flag): Remove.
8110 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8111 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

8115 Avoid code repetition in marker-related functions.
8116 * marker.c (attach_marker): New function.
8117 (Fset_marker, set_marker_restricted, set_marker_both)
8118 (set_marker_restricted_both): Use it.
8119 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8120 Consistently rename charno to charpos.
8121 (marker_position): Add eassert.
8122 (marker_byte_position): Convert to eassert.
8124 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8126 Simplify list operations in unchain_overlay and unchain_marker.
8127 * buffer.c (unchain_overlay): Simplify. Add comment.
8128 * marker.c (unchain_marker): Simplify. Fix comments.
8130 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8132 Introduce fast path for the widely used marker operation.
8133 * alloc.c (build_marker): New function.
8134 * lisp.h (build_marker): New prototype.
8135 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
8136 * composite.c (autocmp_chars): Likewise.
8137 * editfns.c (buildmark): Remove.
8138 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8139 (save_restriction_save): Use build_marker.
8140 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8141 * window.c (save_window_save): Likewise.
8143 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8146 to avoid redundant calls to unchain_overlay.
8147 * buffer.c (drop_overlay): New function.
8148 (delete_all_overlays, Fdelete_overlay): Use it.
8149 * minibuf.c (get_minibuffer): Fix comment.
8151 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8153 Port to OpenBSD 5.1 amd64.
8154 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8155 This is needed for OpenBSD, and should be harmless on all BSD systems.
8156 Also, include <sys/sysctl.h>, as it should be available on all
8157 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8158 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8159 use p_pid member, not kp_proc.pid.
8161 2012-07-06 Glenn Morris <rgm@gnu.org>
8163 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8165 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8167 More xmalloc and related cleanup.
8168 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

8175 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8176 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8178 Omit needless casts involving void * pointers and allocation.
8179 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8180 as the former is more robust if P's type is changed.
8181 Prefer xzalloc to xmalloc + memset 0.
8182 Simplify malloc-or-realloc to realloc.
8183 Don't worry about xmalloc returning a null pointer.
8184 Prefer xstrdup to xmalloc + strcpy.
8185 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8187 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8188 alloca of a constant.
8190 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8192 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8193 hscroll is larger than the line width. Fixes long and futile
8194 looping inside extend_face_to_end_of_line (on a TTY) producing
8195 glyphs that are not needed and thrown away.
8197 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8199 * marker.c (set_marker_restricted_both): Simplify by using
8202 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8204 * editfns.c (region_limit): Simplify by using clip_to_bounds.
8206 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
8208 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
8209 not defined (Bug#11768).

8211 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
8212 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
8213 followed by gtk_box_set_homogeneous (Bug#11768).
8214 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8215 (update_theme_scrollbar_width, xg_create_scroll_bar):
8216 Use gtk_scrollbar_new (Bug#11768).
8217 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8218 (is_box_type): New function (Bug#11768).
8219 (xg_tool_item_stale_p): Call is_box_type.
8220 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8221 with default display (Bug#11768).

8225 * xdisp.c (window_hscroll_limited): New function.
8226 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8227 coordinates when window's hscroll is set to insanely large
8230 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8232 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8235 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8238 * lisp.h (xzalloc): New prototype. Omit needless casts.
8239 * alloc.c (xzalloc): New function. Omit needless casts.
8240 * charset.c: Omit needless casts. Convert all calls to
8241 xmalloc with following memset to xzalloc.

8291 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8293 * fileio.c (time_error_value): Check the right error number.
8294 Problem reported by Troels Nielsen in
8295 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8297 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8299 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8300 This should be fixed in a better way; see Eli Zaretskii in
8301 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8302 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8304 * fileio.c (time_error_value): Rename from special_mtime.
8305 The old name's problems were noted by Eli Zaretskii in
8306 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8308 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8309 This variable's comment says Emacs needs at least one GDB-visible
8310 symbol of type enum pvec_type, to work around GDB problems.
8311 The symbol's value doesn't matter.
8313 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8314 that causes compilation to fail on pre-C99 compilers.
8316 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8318 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8319 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8321 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8323 * buffer.c (init_buffer_once): Fix initialization of
8324 headers for buffer_defaults and buffer_local_symbols.
8325 Reported by Juanma Barranquero <lekktu@gmail.com>.
8327 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8329 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8330 * lisp.h (enum pvec_type): Use fewer bits.
8331 (PSEUDOVECTOR_SIZE_BITS): New constant.
8332 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8333 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8334 change in pvec_type.
8335 (PSEUDOVECTOR_TYPEP): New macro.
8336 (TYPED_PSEUDOVECTORP): Use it.
8337 * fns.c (internal_equal): Adapt code to extract pvectype.

8339 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8340 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8341 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8342 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8343 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8344 abusing vector->header.next.nbytes.
8345 (live_vector_p): Use PVEC_TYPE.
8346 (mark_object): Adapt code to extract pvectype. Use switch.
8348 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8350 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8351 Tighten new eassert a bit.
8353 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8355 Fix compilation with --enable-gcc-warnings and -O1
8357 * doprnt.c (doprnt): Change type of tem to int, initialize
8358 to avoid compiler warning. Add eassert.
8359 * search.c (simple_search): Initialize match_byte to avoid
8360 compiler warning. Add eassert.
8362 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8364 Avoid weird behavior with large horizontal scrolls.
8365 Without this change, for example, large hscroll values would
8366 mess up Emacs's display on Fedora 15 x86, presumably due to
8367 overflows in int calculations in the display code.
8368 Also, if buffers had long lines, Emacs would freeze.
8369 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8370 (set_window_hscroll): New function, containing the old guts of
8371 Fset_window_hscroll. Return the clipped value.
8372 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8373 This avoids the need to check against PTRDIFF_MAX.
8375 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8377 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8379 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8381 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8383 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8384 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8385 since GCC 4.4.6 issues a bogus warning for them.
8387 Fix bugs in file timestamp newness comparisons.
8388 * fileio.c (Ffile_newer_than_file_p):
8389 * lread.c (Fload): Use full timestamp resolution of files,
8390 not just the 1-second resolution, so that files that are only
8391 slightly newer still count as newer.
8392 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8393 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8395 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8397 * fileio.c: Improve handling of file time marker. (Bug#11852)
8398 (special_mtime): New function.
8399 (Finsert_file_contents, Fverify_visited_file_modtime):
8400 Use it to set special mtime values consistently.
8402 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8404 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8405 marker for non-existing file. (Bug#11852)
8407 2012-07-03 Glenn Morris <rgm@gnu.org>
8409 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8410 and did not make it into globals.h).
8412 2012-07-03 Tom Tromey <tromey@redhat.com>
8414 * window.c (Fset_window_margins, Fset_window_fringes)
8415 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8416 * textprop.c (Fprevious_property_change): No longer static.
8417 * syntax.c (Fsyntax_table_p): No longer static.
8418 * process.c (Fget_process, Fprocess_datagram_address): No longer

8432 * dired.c (Ffile_attributes): No longer static.
8433 * composite.c (Fcomposition_get_gstring): No longer static.
8434 * callproc.c (Fgetenv_internal): No longer static.
8436 * ccl.h: Remove EXFUNs.
8437 * buffer.h: Remove EXFUNs.
8438 * dispextern.h: Remove EXFUNs.
8439 * intervals.h: Remove EXFUNs.
8440 * fontset.h: Remove EXFUN.
8441 * font.h: Remove EXFUNs.
8442 * dosfns.c (system_process_attributes): Remove EXFUN.
8443 * keymap.h: Remove EXFUNs.
8444 * lisp.h: Remove EXFUNs.
8445 * w32term.h: Remove EXFUNs.
8446 * window.h: Remove EXFUNs.
8447 * xsettings.h: Remove EXFUN.
8448 * xterm.h: Remove EXFUN.
8450 2012-07-03 Glenn Morris <rgm@gnu.org>
8452 * lisp.h (Frandom): Make it visible to C.
8453 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8454 buffer for invisible buffers. (Bug#1229)
8456 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8458 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8459 values which aren't power of 2.
8460 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8461 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8464 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8466 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8468 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8470 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8472 * alloc.c (allocate_vector_block): Remove redundant
8473 calls to mallopt if DOUG_LEA_MALLOC is defined.
8474 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8475 avoid calls to mallopt if zero_vector is returned.
8477 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8479 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8480 is enabled, avoid dereferencing NULL current_sblock if
8483 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8485 Cleanup basic buffer management.
8486 * buffer.h (struct buffer): Change layout to use generic vector
8487 marking code. Fix some comments. Change type of 'clip_changed'
8488 to bitfield. Remove unused #ifndef old.
8489 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8490 (GET_OVERLAYS_AT): Fix indentation.
8491 (for_each_per_buffer_object_at): New macro.
8492 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8493 (Fbuffer_local_variables): Use it.
8494 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8495 * alloc.c (allocate_buffer): Adjust to match new layout of
8496 struct buffer. Fix comment.
8497 (mark_overlay): New function.
8498 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8499 Lisp area of struct buffer.
8500 (mark_object): Use it. Adjust marking of misc objects
8501 and related comments.
8503 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8505 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8506 wrapper that is not needed because the wrapped code is a no-op (zero
8507 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8508 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8510 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8512 * alloc.c (mark_buffer): Simplify. Remove prototype.
8513 (mark_object): Add comment. Reorganize marking of vector-like
8514 objects. Use CHECK_LIVE for all vector-like objects except buffers
8515 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8516 Avoid redundant calls to mark_vectorlike for bool vectors.
8518 2012-06-30 Glenn Morris <rgm@gnu.org>
8520 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8522 * epaths.in (PATH_SITELOADSEARCH): New.
8523 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8524 This is rather than relying on --enable-locallisppath elements
8525 having "site-lisp" in their names. (Bug#10208#25, 11658)
8527 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8529 * w32proc.c (sys_select): Accept and ignore one more argument.
8531 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8533 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8534 (pselect) [!MS_DOS]: Redirect to sys_select.
8536 * sysdep.c: Don't include dos.h and dosfns.h.
8538 * process.c (sys_select):
8539 * msdos.c (sys_select): Accept one more argument and ignore it.
8541 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8542 adapt data types and code to that.
8545 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8546 which clashes with the gnulib function of the same name.
8548 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8550 * font.c (font_style_to_value, font_style_symbolic)
8551 (font_prop_validate_style): Add type checks for values in
8554 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8556 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8559 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8561 * xdisp.c (try_window_id): Undo last change.
8563 * w32.c (getwd): Adjust commentary about startup_dir.
8564 (init_environment): Always call sys_access, even in non-MSVC
8565 builds. Don't chdir to the directory of the Emacs executable.
8566 This undoes code from 1997 which was justified by the need to
8567 "avoid conflicts when removing and renaming directories". But its
8568 downside was that every relative file name was being interpreted
8569 relative to the directory of the Emacs executable, which can never
8570 be TRT. In particular, it broke sys_access when called with
8571 relative file names.
8572 (sys_access): Map GetLastError to errno.
8574 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8576 * window.h (struct window): Change type of 'fringes_outside_margins'
8577 to bitfield. Fix comment. Adjust users accordingly.
8578 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
8580 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8583 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

8766 Use sprintf return value instead of invoking strlen on result.
8767 In the old days this wasn't portable, since some sprintf
8768 implementations returned char *. But they died out years ago and
8769 Emacs already assumes sprintf returns int.
8770 Similarly for float_to_string.

8779 Use sprintf or float_to_string result to avoid need to call strlen.
8780 * data.c (Fnumber_to_string):
8781 Use make_unibyte_string, since the string must be ASCII.
8782 * lisp.h, print.c (float_to_string): Now returns int length.
8783 * term.c (produce_glyphless_glyph):
8784 Use sprintf result rather than recomputing it.
8786 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8787 * Makefile.in (ALL_CFLAGS):
8788 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8817 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8819 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8822 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8824 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8825 instead of truncating it to 63 (admittedly a generous limit).

8885 * keyboard.c (kbd_buffer_get_event):
8886 * process.c (Faccept_process_output):
8887 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8888 This improves on the previous patch, which introduced a bug
8889 when time_t is unsigned and as wide as intmax_t.
8890 See <http://bugs.gnu.org/9000#51>.
8892 2012-06-23 Eli Zaretskii <eliz@gnu.org>

8955 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8957 Support higher-resolution time stamps (Bug#9000).
8958 The time stamps are only nanosecond-resolution at the C level,
8959 since that's the best that any real-world system supports now.
8960 But they are picosecond-resolution at the Lisp level, as that's
8961 easy, and leaves room for future OS improvements.
8963 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8966 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8967 Don't get current time unless it's needed.
8969 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8970 now provides it if it's absent.
8971 (start_atimer): Port to higher-res time stamps.
8972 Check for time stamp overflow. Don't get current time more
8973 often than is needed.
8975 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8976 Include systime.h, not time.h.
8977 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

8983 (struct image): Timestamp now has higher resolution.
8985 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8986 has at least microseconds now. All uses removed.
8987 (update_frame, update_single_window, update_window, update_frame_1)
8988 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8989 (duration_to_sec_usec): Remove; no longer needed.
8991 * editfns.c (time_overflow): Now extern.
8992 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8993 (float-time, Fformat_time_string, Fcurrent_time_string)

8997 (decode_time_components, lisp_seconds_argument): New functions.
8998 (make_time): Now static.
8999 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9000 Report an error if the time is invalid, rather than having the caller
9003 * fileio.c: Include <stat-time.h>
9004 (Fcopy_file): Copy higher-resolution time stamps.
9005 Prefer to set the time stamp via a file descriptor if that works.
9006 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9007 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9008 (Fvisited_file_modtime, Fset_visited_file_modtime):
9009 Support higher-resolution time stamps.
9011 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9013 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9015 * image.c (prepare_image_for_display, clear_image_cache)
9016 (lookup_image): Port to higer-resolution time stamps.
9018 * keyboard.c (start_polling, bind_polling_period):
9019 Check for time stamp overflow.
9020 (read_char, kbd_buffer_get_event, timer_start_idle)
9021 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9022 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9023 Port to higher-resolution time stamps. Do not assume time_t is signed.
9024 (decode_timer): New function. Timers are now vectors of length 9,
9025 not 8, to accommodate the picosecond component.
9026 (timer_check_2): Use it.
9028 * nsterm.m (select_timeout, timeval_subtract): Remove.
9029 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9030 as they're a bit more accurate and handle overflow better.
9031 (ns_select): Change prototype to be compatible with pselect.
9032 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9033 * nsterm.h (ns_select): Adjust prototype.
9035 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9036 us-resolution time stamps.
9037 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9039 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9041 * lisp.h (time_overflow): New decl.
9042 (wait_reading_process_output): First arg is now intmax_t, not int,
9043 to accommodate larger waits.
9045 * process.h (struct Lisp_Process.read_output_delay):
9046 Now counts nanoseconds, not microseconds.
9047 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9049 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9050 (wait_reading_process_output):
9051 Port to ns-resolution time stamps.
9052 (Faccept_process_output, wait_reading_process_output):
9053 Check for time stamp overflow. Do not assume time_t is signed.
9054 (select_wrapper): Remove; we now use pselect.
9055 (Fprocess_attributes): Now generates ns-resolution time stamps.
9057 * sysdep.c: Include utimens.h. Don't include utime.h
9058 or worry about struct utimbuf; gnulib does that for us now.
9059 (gettimeofday): Remove; gnulib provides a substitute.
9060 (make_timeval): New function.
9061 (set_file_times): Now sets ns-resolution time stamps.
9062 New arg FD; all uses changed.
9063 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9064 (system_process_attributes):
9065 Now returns ns-resolution time stamp. All uses changed.
9066 Check for time stamp overflow.
9068 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9069 provides a substitute now.
9071 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9072 since it guarantees struct timespec.
9073 (EMACS_TIME): Now struct timespec, so that we can support
9074 ns-resolution time stamps.
9075 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9076 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9077 (EMACS_USECS): Remove.
9078 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,

9089 (make_timeval, make_lisp_time, decode_time_components): New decls.
9090 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

9092 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9093 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

9132 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9133 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

9184 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9185 gets killed during executing of this function (Bug#11665).
9186 Try to always return Qt when the buffer has been actually killed.
9187 (Vkill_buffer_query_functions): In doc-string say that functions
9188 run by this hook should not change the current buffer.
9190 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9218 * coding.c (produce_chars): Use ptrdiff_t, not int.
9220 * xterm.c (x_draw_underwave): Check for integer overflow.
9221 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9543 0 items. Allocate new vector from block if vector size is less than
9544 or equal to VBLOCK_BYTES_MAX.
9545 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
9546 (init_alloc_once): Add call to init_vectors.
9548 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
9550 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
9552 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9554 * doprnt.c (doprnt): Truncate multibyte char correctly.
9555 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9556 would mishandle a string argument "Xc" if X was a multibyte
9557 character of length 2: it would truncate after X's first byte
9558 rather than including all of X.
9560 2012-06-06 Chong Yidong <cyd@gnu.org>
9562 * buffer.c (word_wrap): Doc fix.
9564 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
9566 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.

9582 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
9585 2012-06-03 Chong Yidong <cyd@gnu.org>
9587 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
9588 (note_mode_line_or_margin_highlight): If there is no help echo,
9589 use mode-line-default-help-echo. Handle the case where the mouse
9590 position is past the end of the mode line string.
9592 * buffer.c (buffer_local_value_1): New function, split from
9593 Fbuffer_local_value; can return Qunbound.
9594 (Fbuffer_local_value): Use it.
9595 (Vmode_line_format): Docstring tweaks.
9597 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
9599 * sysdep.c (system_process_attributes): Improve comment.
9601 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
9603 * keyboard.c: Export real-this-command to Elisp.
9604 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
9605 and DEFVAR it. Update all users.
9607 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
9609 * minibuf.c (Fassoc_string): Remove duplicate declaration.
9611 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9612 Convert pctcpu and pctmem to Lisp float properly.
9613 Let the compiler fold better, as 100.0/0x8000 is exact.
9615 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9617 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9620 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9622 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9624 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9626 For a 'struct window', replace some Lisp_Object fields to
9627 bitfields where appropriate, remove unused fields.
9628 * window.h (struct window): Remove unused 'last_mark_x' and
9629 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
9630 change its type from Lisp_Object to bitfield.
9631 Change type of 'force_start', 'optional_new_start',
9632 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9633 fields from Lisp_Object to bitfield. Adjust users accordingly.
9635 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9637 Pacify gcc -Wdouble-precision when using Xaw.
9638 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9639 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9640 Use 'float' consistently, rather than 'float' in most places
9641 and 'double' in a couple of places.
9643 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9645 * xdisp.c (handle_stop): Detect whether we have overlay strings
9646 loaded by testing it->current.overlay_string_index to be
9647 non-negative, instead of checking whether n_overlay_strings is
9648 positive. (Bug#11587)
9650 2012-05-31 Chong Yidong <cyd@gnu.org>
9652 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9654 * doc.c (Fsubstitute_command_keys): Doc fix.
9656 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9658 * search.c (search_buffer): Remove calls to
9659 r_alloc_inhibit_buffer_relocation, as it is now called by
9660 maybe_unify_char, which was the cause of relocation of buffer text
9663 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9665 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9666 for the duration of call to load_charset, to avoid problems with
9667 callers of maybe_unify_char that access buffer text through C
9670 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9671 decrement the inhibition flag, instead of just setting or
9674 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9676 Remove obsolete '#define static' cruft.
9677 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9678 This #undef was "temporary" in 2000; it is no longer needed
9679 now that '#define static' has gone away.
9680 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9681 (gray_bitmap_bits): Remove; no longer needed.
9682 All uses replaced with definiens.
9683 * xterm.c: Include "bitmaps/gray.xbm".
9685 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9687 Clean up __executable_start, monstartup when --enable-profiling.
9688 The following changes affect the code only when profiling.
9689 * dispnew.c (__executable_start): Rename from safe_bcopy.
9690 Define only on platforms that need it.
9691 * emacs.c: Include <sys/gmon.h> when profiling.
9692 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9693 (__executable_start): Remove decl, since lisp.h does it now.
9694 (safe_bcopy): Remove decl; no longer has that name.
9695 (main): Coalesce #if into single bit of code, for simplicity.
9696 Cast pointers to uintptr_t, since standard libraries want integers
9698 * lisp.h (__executable_start): New decl.
9700 2012-05-31 Glenn Morris <rgm@gnu.org>
9702 * image.c (Fimagemagick_types): Doc fix.
9704 2012-05-30 Jim Meyering <meyering@redhat.com>
9706 * callproc.c (Fcall_process_region): Include directory component
9707 in mkstemp error message (Bug#11586).

9711 * alloc.c, lisp.h (make_pure_vector): Now static.
9713 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

9716 Move to byte-run.el.
9717 (Fautoload): Do the hash-doc more carefully.
9718 * data.c (Fdefalias): Purify definition, except for keymaps.
9719 (Qdefun): Move from eval.c.
9720 * lisp.h (Qdefun): Remove.
9721 * lread.c (read1): Tiny simplification.
9723 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9725 Do not create empty overlays with the evaporate property (Bug#9642).
9726 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9727 Bug#9642, but explicitly check that the buffer the overlay would
9728 be moved to is live and rearrange lines to make sure that errors
9729 will not put the overlay in an inconsistent state.
9730 (Fdelete_overlay): Cosmetics.
9732 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9734 * w32term.c (my_bring_window_to_top): New function.
9735 (x_raise_frame): Use handle returned by DeferWindowPos, which
9736 could be different from the original one.
9737 Call my_bring_window_to_top instead of my_set_foreground_window.
9740 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9741 by calling BringWindowToTop.
9743 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9744 (WM_EMACS_END): Increase by one.
9746 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9748 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9749 This avoids undefined behavior that might cause the eassert
9750 to not catch an out-of-range value.
9752 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9754 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9755 Update dependencies.
9757 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9759 * bidi.c (bidi_mirror_char): Fix last change.
9761 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9763 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9764 when referring to sectname field in printf format.
9766 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9768 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9769 Only r_alloc_inhibit_buffer_relocation needed to be added;
9770 the others were already declared.
9772 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9773 before checking whether it's out of range. Put the check inside
9775 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9777 2012-05-27 Ken Brown <kbrown@cornell.edu>
9779 * callproc.c (Fcall_process): Restore a line that was accidentally
9780 commented out in the 2011-02-13 change (bug#11547).
9782 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9784 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9785 defined on ralloc.c.
9787 * buffer.c [REL_ALLOC]: Remove prototypes of
9788 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9789 they are now on lisp.h.
9791 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9793 * search.c (search_buffer): Use it to inhibit relocation of buffer
9794 text while re_search_2 is doing its job, because re_search_2 is
9795 passed C pointers to buffer text. (Bug#11519)
9797 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9800 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9801 state after an additional call to move_it_in_display_line_to, keep
9802 the values of it->max_ascent and it->max_descent found for the
9804 (pos_visible_p): Revert the comparison against bottom_y to what it
9805 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9808 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9810 Fix coding-related core dumps with gcc -ftrapv.
9811 The code was computing A - B, where A and B are pointers, and B is
9812 random garbage. This can lead to core dumps on platforms that
9813 have special pointer registers, and it also leads to core dumps on
9814 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9815 A - B only when B is initialized properly.
9816 * coding.c (coding_set_source, coding_set_destination): Return void.
9817 (coding_change_source, coding_change_destinations): New functions,
9818 with the old behaviors of coding_set_source and coding_set_destination.
9819 All callers that need an offset changed to use these new functions.
9821 2012-05-26 Glenn Morris <rgm@gnu.org>
9823 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9825 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9827 Extend mouse support on W32 text-mode console.
9828 * xdisp.c (draw_row_with_mouse_face):
9829 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9831 * w32console.c: Include window.h.
9832 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9834 (initialize_w32_display): Initialize mouse-highlight data.
9836 * w32inevt.c: Include termchar.h and window.h.
9837 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9838 moves, call note_mouse_highlight. If help_echo changed, call
9839 gen_help_event to produce help-echo message in the echo area.
9840 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9843 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9845 * lread.c (read1): Simplify slightly to avoid an overflow warning
9846 with GCC 4.7.0 on x86-64.
9848 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9850 * bidi.c (bidi_mirror_char): Revert last change: an int is
9851 definitely wide enough here.
9853 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9855 Fix integer width and related bugs (Bug#9874).
9856 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9857 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
9858 (string_bytes, check_sblock, allocate_string_data):
9859 (compact_small_strings, Fmake_bool_vector, make_string)
9860 (make_unibyte_string, make_multibyte_string)
9861 (make_string_from_bytes, make_specified_string)
9862 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
9863 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9865 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9866 (allocate_pseudovector):
9867 Use int, not EMACS_INT, where int is wide enough.
9868 (inhibit_garbage_collection, Fgarbage_collect):
9869 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9870 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9871 int might not be wide enough.
9872 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9873 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
9874 (bidi_at_paragraph_end, bidi_find_paragraph_start)
9875 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9876 (bidi_level_of_next_char, bidi_move_to_visually_next):
9877 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9878 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9879 (Fkill_buffer, Fset_buffer_major_mode)
9880 (advance_to_char_boundary, Fbuffer_swap_text)
9881 (Fset_buffer_multibyte, overlays_at, overlays_in)
9882 (overlay_touches_p, struct sortvec, record_overlay_string)
9883 (overlay_strings, recenter_overlay_lists)
9884 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9885 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9886 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9887 (Foverlay_recenter, last_overlay_modification_hooks_used)
9888 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9889 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9890 (validate_region): Omit unnecessary test for b <= e,
9891 since that's guaranteed by the previous test.
9892 (adjust_overlays_for_delete): Avoid pos + length overflow.
9893 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9894 (report_overlay_modification):
9895 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9896 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9897 Omit pointer cast, which isn't needed anyway, and doesn't work
9898 after the EMACS_INT -> ptrdiff_t change.
9899 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9900 * buffer.h: Adjust decls to match defn changes elsewhere.
9901 (struct buffer_text, struct buffer):
9902 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9903 Use EMACS_INT, not int, where int might not be wide enough.
9904 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9905 not int, to avoid needless 32-bit limit on 64-bit hosts.
9906 (exec_byte_code): Use tighter memory-full test, one that checks
9907 for alloca overflow. Don't compute the address of the object just
9908 before an array, as that's not portable. Use EMACS_INT, not
9909 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9910 * callint.c (Fcall_interactively):
9911 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9912 * callproc.c (call_process_kill, Fcall_process):
9913 Don't assume pid_t fits into an Emacs fixnum.
9914 (call_process_cleanup, Fcall_process, child_setup):
9915 Don't assume pid_t fits into int.
9916 (call_process_cleanup, Fcall_process, delete_temp_file)
9917 (Fcall_process_region):
9918 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9919 (Fcall_process): Simplify handling of volatile integers.
9920 Use int, not EMACS_INT, where int will do.
9921 * casefiddle.c (casify_object, casify_region, operate_on_word)
9922 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9923 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9924 (casify_object): Avoid integer overflow when overallocating buffer.
9925 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9926 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9927 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9928 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9929 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9930 integers are now checked earlier. All uses replaced with XINT.
9932 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9933 For CCL_MapSingle, check that content and value are in int range.
9934 (ccl_driver, Fregister_code_conversion_map):
9935 Check that Vcode_version_map_vector is a vector.
9936 (resolve_symbol_ccl_program): Check that vector header is in range.
9937 Always copy the vector, so that we can check its contents reliably
9938 now rather than having to recheck each instruction as it's being
9939 executed. Check that vector words fit in 'int'.
9940 (ccl_get_compiled_code, Fregister_ccl_program)
9941 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9942 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9943 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9944 contents are in range.
9945 (Fccl_execute_on_string): Check that status is in range.
9946 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9947 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9948 Accept and return EMACS_INT, not int, because callers can pass values
9950 (c_string_width, strwidth, lisp_string_width, chars_in_text)
9951 (multibyte_chars_in_text, parse_str_as_multibyte)
9952 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
9953 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9954 (string_escape_byte8, Fget_byte):
9955 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9956 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9957 avoid mishandling large integers.
9958 * character.h: Adjust decls to match defn changes elsewhere.
9959 * charset.c (load_charset_map_from_file, find_charsets_in_text)
9960 (Ffind_charset_region):
9961 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9962 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
9963 (load_charset_map_from_vector, Fdefine_charset_internal):
9964 Don't assume fixnum fits in int.
9965 (load_charset_map_from_vector, Fmap_charset_chars):
9966 Remove now-unnecessary CHECK_NATNUMs.
9967 (Fdefine_charset_internal): Check ranges here, more carefully.
9968 Don't rely on undefined behavior with signed left shift overflow.
9969 Don't assume unsigned int fits into fixnum, or that fixnum fits
9970 into unsigned int. Don't require max_code to be a valid fixnum;
9971 that's not true for gb10830 4-byte on a 32-bit host. Allow
9972 invalid_code to be a cons, for the same reason. Require code_offset
9973 to be a character. Avoid int overflow if max_char is close
9975 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9976 this is intended anyway and avoids some undefined behavior.
9977 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9978 INDEX_TO_CODE_POINT, as that's what it expects.
9979 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9980 * charset.h (DECODE_CHAR): Return int, not unsigned;
9981 this is what was intended anyway, and it avoids undefined behavior.
9982 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9983 integer-overflow issues.
9984 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.

10655 2012-05-25 Glenn Morris <rgm@gnu.org>
10657 * lisp.mk (lisp): Update for more files being compiled now.
10659 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
10661 * lread.c: Remove `read_pure' which makes no difference.
10662 (read_pure): Remove var.
10663 (unreadpure): Remove function.
10664 (readevalloop): Don't call read_list with -1 flag.
10665 (read1, read_vector): Don't test read_pure any more.
10666 (read_list): Simplify.
10668 * fileio.c, character.h: Minor style tweaks.
10670 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
10672 * window.h (clip_changed): Remove useless declaration.
10674 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
10676 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
10677 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
10679 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
10682 This directory predates autoconf and is no longer needed nowadays.
10683 Move its few remaining bits of functionality to where they're needed.
10684 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
10685 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
10686 * m/template.h: Remove.
10687 * Makefile.in (M_FILE): Remove. All uses removed.
10688 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
10689 * lisp.h (USE_LSB_TAG):
10690 * mem-limits.h (EXCEEDS_LISP_PTR):
10691 Use VAL_MAX, not VALBITS, in #if.
10692 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
10693 (EMACS_UINT): Define unconditionally now.
10694 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
10695 (BITS_PER_EMACS_INT): New constants, replacing
10696 what used to be in config.h, but not useful in #if.
10697 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
10698 define them any more.
10699 (VAL_MAX): New macro.
10701 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
10702 BITS_PER_EMACS_INT, in #if.
10703 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
10704 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
10705 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
10706 * s/ms-w32.h (DATA_START):
10707 Move here from removed file m/intel386.h.
10708 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
10709 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
10711 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
10713 Assume C89 or later.
10714 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
10715 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
10717 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
10718 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
10719 * textprop.c, tparam.c (NULL): Remove.
10720 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
10721 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
10722 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
10723 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
10724 * xterm.c (input_signal_count): Assume volatile works.
10726 2012-05-21 Ken Brown <kbrown@cornell.edu>
10728 * xgselect.c (xg_select): Fix first argument in call to 'select'
10731 2012-05-20 Ken Brown <kbrown@cornell.edu>
10733 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
10734 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
10736 2012-05-19 Ken Brown <kbrown@cornell.edu>
10738 * xfns.c (x_in_use): Remove `static' qualifier.
10739 * xterm.h (x_in_use): Declare.
10740 * xgselect.c: Include xterm.h.
10741 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
10742 and `display_arg' (bug#9754).
10744 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
10746 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
10748 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
10749 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
10751 2012-05-18 Eli Zaretskii <eliz@gnu.org>
10753 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
10755 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
10756 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
10758 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
10759 reference to image_cache->refcount.
10760 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10762 2012-05-17 Juri Linkov <juri@jurta.org>
10764 * search.c (Fword_search_regexp, Fword_search_backward)
10765 (Fword_search_forward, Fword_search_backward_lax)
10766 (Fword_search_forward_lax): Move functions to isearch.el
10767 (bug#10145, bug#11381).
10769 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10771 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10773 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10775 * lread.c (init_obarray): Declare Qt and Qnil as special.
10777 2012-05-14 Glenn Morris <rgm@gnu.org>
10779 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10780 Put "libexec" before "bin", for the sake of init_callproc_1.
10782 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10784 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10786 * unexaix.c: Port to more-recent AIX compilers.
10787 (report_error, report_error_1, make_hdr, copy_sym)
10788 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10789 Make arguments const char *, not char *, to avoid violations of C
10790 standard and to fix some AIX warnings reported by Gilles Pion.
10792 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10794 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10795 already have overlays loaded.
10796 (handle_single_display_spec): Before returning without displaying
10797 fringe bitmap, synchronize the bidi iterator with the main display
10798 iterator, by calling iterate_out_of_display_property.
10799 (iterate_out_of_display_property): Detect buffer iteration by
10800 testing that it->string is a Lisp string.
10801 (get_next_display_element): When the current object is exhausted,
10802 and there's something on it->stack, call set_iterator_to_next to
10803 proceed with what's on the stack, instead of returning zero.
10804 (set_iterator_to_next): If called at the end of a Lisp string,
10805 proceed to consider_string_end without incrementing string
10806 position. Don't increment display vector index past the end of
10807 the display vector. (Bug#11417)
10808 (pos_visible_p): Don't report a position visible when move_it_to
10809 stopped at the last line of window, which happens to be scanned
10810 backwards by the bidi iteration. (Bug#11464)
10812 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10814 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10815 and right-margin display specs even if the spec is invalid or we
10816 are on a TTY, and thus unable to display on the fringes.
10817 That's because the text with the property will not be displayed anyway,
10818 so we need to signal to the caller that this is a "replacing"
10819 display spec. This fixes display when the spec is invalid or we
10822 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10824 * unexaix.c (make_hdr): Fix typo in prototype.
10825 This bug broke the build on AIX. Problem reported by Gilles Pion.
10827 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10829 * keyboard.c (kbd_buffer_get_event): Read special events also in
10830 batch mode. (Bug#11415)
10832 2012-05-12 Glenn Morris <rgm@gnu.org>
10834 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10836 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10838 * lisp.mk (lisp): Add newcomment.elc.
10840 2012-05-12 Glenn Morris <rgm@gnu.org>
10842 * Makefile.in (MKDIR_P): New, set by configure.
10843 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10845 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10847 Remove unused function hourglass_started.
10848 * dispextern.h (hourglass_started):
10849 * w32fns.c (hourglass_started):
10850 * xdisp.c (hourglass_started): Remove.
10852 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10854 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10855 Update dependencies.
10857 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10859 * xgselect.c (xg_select): Put maxfds+1 into a var.
10860 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10862 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10864 2012-05-10 Dave Abrahams <dave@boostpro.com>
10866 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10867 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10869 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10871 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10872 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
10873 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10874 Initialize xd_registered_buses.
10876 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10878 Untag more efficiently if USE_LSB_TAG.
10879 This is based on a proposal by YAMAMOTO Mitsuharu in
10880 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10881 For an admittedly artificial (nth 8000 longlist) benchmark on
10882 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10883 Emacs's overall text size by 1%.
10884 * lisp.h (XUNTAG): New macro.
10885 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10886 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10887 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10888 * eval.c (Fautoload):
10889 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10890 * frame.h (XFRAME): Use XUNTAG.
10892 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10893 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10894 Remove unportable assumptions about print widths of types like
10896 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10897 intptr_t when converting between pointer and integer, to avoid GCC
10898 warnings about wrong width.
10900 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10902 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10903 stack for each reader_thread, instead of defaulting to 8MB
10904 determined by the linker. This avoids failures in creating
10905 subprocesses on Windows 7, see the discussion in this thread:
10906 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10908 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10910 Fix up display of the *Minibuf-0* buffer in the mini window.
10911 * keyboard.c (read_char): Don't clear the echo area if there's no
10913 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10914 contents of *Minibuf-0*) if there's no message displayed in its stead.
10916 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10918 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10921 2012-05-06 Chong Yidong <cyd@gnu.org>
10923 * lisp.mk (lisp): Update.
10925 2012-05-05 Jim Meyering <meyering@redhat.com>
10927 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10929 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10931 * data.c (PUT_ERROR): New macro.
10932 (syms_of_data): Use it. Add new error type `user-error'.
10933 * undo.c (user_error): New function.
10934 (Fprimitive_undo): Use it.
10935 * print.c (print_error_message): Adjust print style for `user-error'.
10936 * keyboard.c (user_error): New function.
10937 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10939 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10941 Do not limit current-time-string to years 1000..9999.
10942 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10943 (Fcurrent_time_string): Support any year that is supported by the
10944 underlying localtime representation. Don't use asctime, as it
10945 has undefined behavior for years outside the range -999..9999.
10947 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10949 Fix race conditions involving setenv, gmtime, localtime, asctime.
10950 Without this fix, interrupts could mess up code that uses these
10951 nonreentrant functions, since setting TZ invalidates existing
10952 tm_zone or tzname values, and since most of these functions return
10953 pointers to static storage.
10954 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10955 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10956 Grow the critical sections to include not just invoking
10957 localtime/gmtime, but also accessing these functions' results
10958 including their tm_zone values if any, and any related TZ setting.
10959 (format_time_string): Last arg is now struct tm *, not struct tm **,
10960 so that the struct tm is saved in the critical section.
10961 All callers changed. Simplify allocation of initial buffer, partly
10962 motivated by the fact that memory allocation needs to be outside
10963 the critical section.
10965 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10967 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10968 with RESET_INTERVAL.
10970 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10971 Remove duplicated buffer name initialization.
10973 2012-05-02 Jim Meyering <jim@meyering.net>
10975 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10977 * xfns.c (x_window): Use xstrdup (Bug#11375).
10979 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10981 * xdisp.c (pos_visible_p): If already at a newline from the
10982 display string before the 'while' loop, don't walk back the glyphs
10983 from it3.glyph_row. Solves assertion violation when the display
10984 string begins with a newline (egg.el). (Bug#11367)
10986 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10988 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10991 2012-05-01 Glenn Morris <rgm@gnu.org>
10993 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10994 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10995 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10996 All were removed before 23.1.
10998 * dispnew.c: Remove HAVE_LIBNCURSES test;
10999 it is always true on relevant platforms.
11001 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11002 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11004 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11006 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11008 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11009 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11012 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11014 Do not avoid creating empty evaporating overlays (Bug#9642).
11015 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11016 That is, do not delete an evaporating overlay if it becomes
11017 empty after its bounds are adjusted to fit within its buffer.
11018 This fix caused other problems, and I'm reverting it until we get
11019 to the bottom of them.
11021 2012-04-27 Chong Yidong <cyd@gnu.org>
11023 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11025 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11027 * xdisp.c (pos_visible_p): If the window start position is beyond
11028 ZV, start the display from buffer beginning. Prevents assertion
11029 violation in init_iterator when the minibuffer window is scrolled
11030 via the scroll bar.
11032 * window.c (window_scroll_pixel_based): Likewise.
11034 2012-04-27 Chong Yidong <cyd@gnu.org>
11036 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11038 2012-04-27 Glenn Morris <rgm@gnu.org>
11040 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11041 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11043 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11045 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11046 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11048 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11050 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11051 display element, check also the underlying string or buffer
11052 character. (Bug#11341)
11054 * w32menu.c: Include w32heap.h.
11055 (add_menu_item): If the call to AppendMenuW (via
11056 unicode_append_menu) fails, disable Unicode menus only if we are
11057 running on Windows 9X/Me.
11059 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11061 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11062 (xgetint): Add missing shift for LSB tags.
11064 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11066 * keyboard.c (read_char): Don't wipe echo area for select window
11067 events: These might get delayed via `mouse-autoselect-window'
11070 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11072 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11073 manipulation of :loaded-from data.
11075 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11077 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11078 now a cons (bug#11311).
11080 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11082 Do not create empty overlays with the evaporate property (Bug#9642).
11083 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11084 if it becomes empty after its bounds are adjusted to fit within
11085 its buffer. Without this fix, in a nonempty buffer (let ((o
11086 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11087 yields an empty overlay that has the evaporate property, which is
11088 not supposed to happen.
11090 Fix minor GTK3 problems found by static checking.
11091 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11092 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11093 (struct _EmacsFixedClass, emacs_fixed_get_type):
11094 Move decls here from emacsgtkfixed.h, since they needn't be public.
11095 (emacs_fixed_get_type): Now static.
11096 (emacs_fixed_class_init): Omit unused local.

11292 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11293 (NEED_MEM_INSERT): New macro.
11294 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11295 Remove one incorrect comment and fix another.

11362 2012-04-11 Daniel Colascione <dancol@dancol.org>
11364 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11365 against is gone. It's better to use vfork now so that when Cygwin
11366 gains a new, working vfork, we use it automatically (bug#10398).
11368 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11421 * minibuf.c (Fread_variable): Callers changed.
11423 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11425 * xdisp.c (set_cursor_from_row): If the display string appears in
11426 the buffer at position that is closer to point than the position
11427 after the display string, display the cursor on the first glyph of
11428 the display string. Fixes cursor display when a 'display' text
11429 property immediately follows invisible text. (Bug#11094)
11431 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11433 composite.c: use 'double' consistently
11434 * composite.c (get_composition_id): Use 'double' consistently
11435 instead of converting 'float' to 'double' and vice versa; this is
11436 easier to understand and avoids a GCC warning.
11438 2012-04-09 Glenn Morris <rgm@gnu.org>

11490 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11492 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

11505 point, use it.vpos to compute how many lines to backtrack after
11506 move_it_to point. (Bug#11133)
11508 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11510 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11511 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11512 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11513 macros related to unification of CJK characters. For the details,
11514 see the discussion following the message here:

11531 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11533 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11534 position we get to after a call to move_it_to fails the
11535 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11536 only if we wind up in a string from display property. (Bug#11063)
11538 * window.c (Fdelete_other_windows_internal): Invalidate the row
11539 and column information about mouse highlight, so that redisplay
11540 restores it after reallocating the glyph matrices. (Bug#7464)
11542 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11543 string comes from a `display' text property, use the buffer
11544 position of that property as if we actually saw that position in
11546 (move_it_by_lines): Remove the assertion that
11547 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11548 violated when there's a before-string at the beginning of a line.
11551 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11553 * xdisp.c (append_space_for_newline): If the default face was
11554 remapped, use the remapped face for the appended newline.
11555 (extend_face_to_end_of_line): Use the remapped default face for
11556 extending the face to the end of the line.
11557 (display_line): Call extend_face_to_end_of_line when the default
11558 face was remapped. (Bug#11068)
11560 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11562 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11564 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11566 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11568 2012-03-27 Glenn Morris <rgm@gnu.org>
11570 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11573 2012-03-26 Kenichi Handa <handa@m17n.org>
11575 * dispextern.h (struct glyph): Fix previous change. Change the
11576 bit length of glyphless.ch to 25 (Bug#11082).
11578 2012-03-26 Chong Yidong <cyd@gnu.org>
11580 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11581 (command_loop_1): Use it; inhibit selection update for
11582 handle-select-window too (Bug#8996).
11584 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11586 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11588 2012-03-25 Kenichi Handa <handa@m17n.org>
11590 * dispextern.h (struct glyph): Change the bit length of
11591 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11593 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11595 * s/ms-w32.h (tzname): Include time.h before redirecting to
11596 _tzname. Fixes the MSVC build. (Bug#9960)
11598 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11600 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11603 * xterm.c (XTread_socket): Only modify handling_signal if
11604 !SYNC_INPUT. (Bug#11080)
11606 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11608 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11609 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11610 when fetching a multibyte character consumes more bytes than
11611 CHAR_BYTES returns, due to unification of CJK characters in
11612 string_char. (Bug#11073)
11614 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11616 * process.c (wait_reading_process_output): Handle pty disconnect
11617 by refraining from sending oneself a SIGCHLD (bug#10933).
11619 2012-03-22 Chong Yidong <cyd@gnu.org>
11621 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11623 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11624 Mark string as coming from a prefix property.
11625 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11626 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11628 2012-03-21 Chong Yidong <cyd@gnu.org>
11630 * xfaces.c (Vface_remapping_alist): Doc fix.
11632 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11634 * w32proc.c (Fw32_set_console_codepage)
11635 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
11638 2012-03-20 Chong Yidong <cyd@gnu.org>
11640 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
11641 to reflect default non-nil value of redisplay-dont-pause.
11643 2012-03-19 Kenichi Handa <handa@m17n.org>
11645 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11646 it fit in a valid range (Bug#11003).
11648 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11650 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11651 that is not from display property, accept the row as a "cursor
11652 row" if one of the string's character has a non-nil `cursor'
11653 property. Fixes cursor positioning when there are newlines in
11654 overlay strings, e.g. in icomplete.el. (Bug#11035)
11656 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11658 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11660 2012-03-12 Chong Yidong <cyd@gnu.org>
11662 * eval.c (inhibit_lisp_code): Rename from
11663 inhibit_window_configuration_change_hook; move from window.c.
11665 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11666 * window.c (run_window_configuration_change_hook)
11667 (syms_of_window): Callers changed.
11669 2012-03-11 Chong Yidong <cyd@gnu.org>
11671 * keymap.c (Fkey_description): Doc fix (Bug#9700).
11673 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
11675 2012-03-10 Chong Yidong <cyd@gnu.org>
11677 * frame.c (other_visible_frames): Don't assume the selected frame
11678 is visible (Bug#10955).
11680 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11682 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11684 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11686 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11687 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11690 2012-03-03 Glenn Morris <rgm@gnu.org>
11692 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11694 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11696 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11697 position past the first glyph_row that ends at ZV. (Bug#10902)
11698 (redisplay_window, next_element_from_string): Fix typos in
11700 (redisplay_window): Pass to move_it_vertically the margin in
11701 pixels, not in screen lines.
11703 2012-03-02 Glenn Morris <rgm@gnu.org>
11705 * buffer.c (buffer-list-update-hook): Doc fix.
11707 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11709 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11710 push_it before setting up the iterator for the first overlay
11711 string, even if we have an empty string loaded.
11712 (next_overlay_string): If there's an empty string on the iterator
11713 stack, pop the stack. (Bug#10903)
11715 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11717 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11718 Suggested by Stefan Monnier in
11719 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11720 * alloc.c (widen_to_Lisp_Object): New static function.
11721 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11722 and widening them to Lisp_Objects. This would work even if
11723 USE_LSB_TAG is defined and wide integers are used, which might
11724 happen in a future version of Emacs.
11726 2012-02-25 Chong Yidong <cyd@gnu.org>
11728 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11731 * xselect.c (Fx_selection_exists_p): Doc fix.
11732 (x_clipboard_manager_save_all): Print an informative message
11733 before saving to clipboard manager.
11735 2012-02-24 Chong Yidong <cyd@gnu.org>
11737 * keyboard.c (process_special_events): Handle all X selection
11738 requests in kbd_buffer, not just the next one (Bug#8869).
11740 2012-02-23 Chong Yidong <cyd@gnu.org>
11742 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11743 call when setting menu-bar-lines and tool-bar-lines parameters.
11744 (unwind_create_frame_1): New helper function.
11746 * window.c (inhibit_window_configuration_change_hook): New var.
11747 (run_window_configuration_change_hook): Obey it.
11748 (syms_of_window): Initialize it.
11750 2012-02-22 Chong Yidong <cyd@gnu.org>
11752 * xterm.c (x_draw_image_relief): Add missing type check for
11753 Vtool_bar_button_margin (Bug#10743).
11755 2012-02-21 Chong Yidong <cyd@gnu.org>
11757 * fileio.c (Vfile_name_handler_alist): Doc fix.
11759 * buffer.c (Fget_file_buffer): Protect against invalid file
11760 handler return value.
11762 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
11764 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11765 when computing $valmask.
11767 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11768 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11769 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11770 It's useless in that case, and it can cause problems on hosts
11771 that allocate halves of EMACS_INT values separately.
11772 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11773 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11774 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11775 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11776 it avoids undefined behavior on hosts where shifting right by more
11777 than the word width has undefined behavior.
11779 2012-02-19 Chong Yidong <cyd@gnu.org>
11781 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11782 (Funhandled_file_name_directory, Ffile_name_as_directory)
11783 (Fdirectory_file_name, Fexpand_file_name)
11784 (Fsubstitute_in_file_name): Protect against invalid file handler
11785 return values (Bug#10845).
11787 2012-02-18 Eli Zaretskii <eliz@gnu.org>
11789 * .gdbinit (pitx): Fix incorrect references to fields of the
11792 2012-02-17 Chong Yidong <cyd@gnu.org>

11796 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
11798 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
11799 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11801 2012-02-15 Chong Yidong <cyd@gnu.org>
11803 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11804 marked as special. Also, starting docstrings with * is obsolete.
11806 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
11808 * gnutls.c (emacs_gnutls_write): Fix last change.
11810 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
11812 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
11815 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
11817 * keymap.c (Fsingle_key_description): Handle char ranges.
11819 2012-02-12 Chong Yidong <cyd@gnu.org>
11821 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11822 as that creates a dangerous corner case.
11824 * window.c (Fdelete_window_internal): Invalidate the mouse
11825 highlight (Bug#9904).
11827 2012-02-12 Glenn Morris <rgm@gnu.org>
11829 * xselect.c (Fx_own_selection_internal)
11830 (Fx_get_selection_internal, Fx_disown_selection_internal)
11831 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
11832 * nsselect.m (Fx_own_selection_internal)
11833 (Fx_disown_selection_internal, Fx_selection_exists_p)
11834 (Fx_selection_owner_p, Fx_get_selection_internal):
11835 Sync docs and argument specs with the xselect.c versions.
11837 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
11839 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
11841 2012-02-11 Eli Zaretskii <eliz@gnu.org>
11843 * w32select.c (Fx_selection_exists_p): Sync doc string and
11844 argument list with xselect.c. (Bug#10783)
11846 * w16select.c (Fx_selection_exists_p): Sync doc string and
11847 argument list with xselect.c. (Bug#10783)

11851 * fns.c (Fsecure_hash): Doc fix.
11853 2012-02-09 Kenichi Handa <handa@m17n.org>
11855 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
11857 2012-02-07 Chong Yidong <cyd@gnu.org>
11859 * buffer.c (Fbuffer_local_variables)
11860 (buffer_lisp_local_variables): Handle unbound vars correctly;
11861 don't let Qunbound leak into Lisp.
11863 2012-02-07 Glenn Morris <rgm@gnu.org>
11865 * image.c (Fimagemagick_types): Doc fix.
11867 * image.c (imagemagick-render-type): Change it from a lisp object
11868 to an integer. Move the doc here from the lisp manual.
11869 Treat all values not equal to 0 the same.
11871 2012-02-06 Chong Yidong <cyd@gnu.org>
11873 * doc.c (store_function_docstring): Avoid applying docstring of
11874 alias to base function (Bug#2603).
11876 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>

11881 2012-02-04 Chong Yidong <cyd@gnu.org>
11883 * nsterm.m: Declare a global (Bug#10694).
11885 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11887 * w32.c (get_emacs_configuration_options):
11888 Include --enable-checking, if specified, in the return value.
11890 2012-02-04 Martin Rudalics <rudalics@gmx.at>
11892 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
11893 after rounding frame sizes. (Bug#9723)
11895 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11897 * keyboard.c (adjust_point_for_property): Don't position point
11898 before BEGV. (Bug#10696)
11900 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11902 Handle overflow when computing char display width (Bug#9496).
11903 * character.c (char_width): Return EMACS_INT, not int.
11904 (char_width, c_string_width): Check for overflow when
11905 computing the width; this is possible now that individual
11906 characters can have unbounded width. Problem introduced
11907 by merge from Emacs 23 on 2012-01-19.
11909 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
11911 * dbusbind.c (Fdbus_register_method): Mention the return value
11912 :ignore in the docstring.
11914 2012-02-02 Glenn Morris <rgm@gnu.org>
11916 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
11918 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
11919 Unconditionally set to t. (Bug#10673)

11924 2012-02-02 Kenichi Handa <handa@m17n.org>
11926 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
11927 0, do not call append_composite_glyph.
11929 2012-02-02 Kenichi Handa <handa@m17n.org>
11931 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11933 (x_produce_glyphs): If the component of a composition is a null
11934 string, set it->pixel_width to 1 to avoid zero-width glyph.
11936 2012-02-01 Eli Zaretskii <eliz@gnu.org>
11938 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11939 first 2 arguments are identical. This makes inserting large
11940 output from a subprocess an order of magnitude faster on
11941 MS-Windows, where all sbrk'ed memory is always contiguous.
11943 2012-01-31 Glenn Morris <rgm@gnu.org>
11945 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

11981 2012-01-21 Chong Yidong <cyd@gnu.org>
11983 * floatfns.c (Fcopysign): Make the second argument non-optional,
11984 since nil is not allowed anyway.
11986 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
11988 * process.c (read_process_output): Use p instead of XPROCESS (proc).
11989 (send_process): Likewise.
11991 2012-01-19 Martin Rudalics <rudalics@gmx.at>
11993 * window.c (save_window_save, Fcurrent_window_configuration)
11994 (Vwindow_persistent_parameters): Do not use Qstate.
11995 Rewrite doc-strings.
11997 2012-01-19 Kenichi Handa <handa@m17n.org>
11999 * character.c (char_width): New function.
12000 (Fchar_width, c_string_width, lisp_string_width):
12001 Use char_width (Bug#9496).
12003 2012-01-16 Martin Rudalics <rudalics@gmx.at>
12005 * window.c (Vwindow_persistent_parameters): New variable.
12006 (Fset_window_configuration, save_window_save): Handle persistent
12009 2012-01-14 Eli Zaretskii <eliz@gnu.org>
12011 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
12012 thrashing the stack of the thread. (Bug#9087)
12014 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>

12556 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
12557 Otherwise, valgrind does not work on some platforms.
12558 Problem reported by Andreas Schwab in
12559 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12560 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12561 is set, removing the need for VIRT_ADDRESS_VARIES.
12562 (PURE_P): Use a more-efficient implementation that needs just one
12563 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12564 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12565 to 4 (xorl, subq, cmpq, setbe).
12566 * alloc.c (pure): Always extern now, since that's the
12567 VIRT_ADDR_VARIES behavior.
12568 (PURE_POINTER_P): Use a single comparison, not two, for
12569 consistency with the new puresize.h.
12570 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12571 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12579 behave as if the cursor position were at the window margin.
12581 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12582 and the cursor position is out of bounds, behave as if the cursor
12583 position were at the window margin. (Bug#10075)
12585 2011-11-18 Chong Yidong <cyd@gnu.org>
12587 * window.c (Fwindow_combination_limit): Make first argument

12609 compute_line_metrics.
12610 (compute_line_metrics): Call row_hash, instead of computing the
12613 * dispnew.c (verify_row_hash): Call row_hash for computing the
12614 hash code of a row, instead of duplicating code from xdisp.c.
12616 * dispextern.h (row_hash): Add prototype.
12618 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

12654 2011-11-14 Eli Zaretskii <eliz@gnu.org>
12656 * xdisp.c (display_line): Move the call to
12657 highlight_trailing_whitespace before the call to
12658 compute_line_metrics, since the latter needs to see the final
12659 faces of all the glyphs to compute ROW's hash value.
12660 Fixes assertion violations in row_equal_p. (Bug#10035)
12662 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
12664 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

12669 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12670 with user-defined heap size. Bump the default size of the temacs

12674 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12675 current_matrix and desired_matrix. (Bug#9990)
12676 (verify_row_hash) [XASSERTS]: New function.

12723 Avoid some portability problems by eschewing 'extern inline' functions.
12724 The trivial performance wins aren't worth the portability hassles; see

12793 * xmenu.c (cleanup_widget_value_tree): New function.
12794 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

12801 (window_box_width, window_box_left, window_box_left_offset)
12802 (window_box_right, window_box_right_offset): Declare extern.
12803 Otherwise, these inline functions do not conform to C99 and
12804 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12805 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12806 * intervals.c (adjust_intervals_for_insertion)

12809 (static_offset_intervals): Remove.
12810 (offset_intervals): Rewrite using the old contents of
12811 static_offset_intervals. The old version didn't conform to C99

12943 2011-11-01 Eli Zaretskii <eliz@gnu.org>
12945 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
12946 Don't stop backward scan on the continuation glyph, even though
12947 its CHARPOS is positive.
12948 (mouse_face_from_buffer_pos, note_mouse_highlight):
12949 Rename cover_string to disp_string.
12951 2011-11-01 Martin Rudalics <rudalics@gmx.at>
12953 * window.c (temp_output_buffer_show): Don't use
12954 Vtemp_buffer_show_specifiers.
12955 (Vtemp_buffer_show_specifiers): Remove unused variable.
12957 2011-10-30 Eli Zaretskii <eliz@gnu.org>
12959 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
12960 past the beginning of the current glyph matrix.
12962 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
12964 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
12965 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
12966 HAVE_GTK3 (Bug#9869).
12968 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
12969 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
12971 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
12973 * xterm.c: Declare x_handle_net_wm_state to return int.
12974 (handle_one_xevent): Check if we are iconified but don't have
12975 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
12976 (get_current_wm_state): Return non-zero if not hidden,
12977 check for _NET_WM_STATE_HIDDEN (Bug#9893).
12978 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
12979 (x_handle_net_wm_state): Return what get_current_wm_state returns.
12980 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
12982 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
12984 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
12985 so that this new function doesn't get optimized away by a
12986 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
12988 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
12990 * frame.h (MOUSE_HL_INFO): Remove excess parens.
12992 2011-10-29 Eli Zaretskii <eliz@gnu.org>
12994 Fix the `xbytecode' command.
12995 * .gdbinit (xprintbytestr): New command.
12996 (xwhichsymbols): Rename from `which'; all callers changed.
12997 (xbytecode): Print the byte-code string as well.
12999 2011-10-29 Kim Storm <storm@cua.dk>
13001 * alloc.c (which_symbols): New function.
13003 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
13005 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
13008 2011-10-29 Glenn Morris <rgm@gnu.org>
13010 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
13011 Not clear what it was for, and it causes various bugs. (Bug#9839)
13013 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13015 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
13016 possible random value that matches one of those tested as
13017 condition to clear the mouse face.
13019 2011-10-28 Chong Yidong <cyd@gnu.org>
13021 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
13023 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
13025 * window.c (make_window): Initialize phys_cursor_on_p.
13027 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
13029 * lisp.h (struct Lisp_Symbol): Update comments.
13031 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
13033 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
13035 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13037 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13038 <oslsachem@gmail.com> for helping to debug this.
13040 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13041 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13042 (g_b_init_get_glyph_outline_w): New static variables.
13043 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
13044 (GetGlyphOutlineW_Proc): New typedefs.
13045 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
13046 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13048 (w32font_open_internal, compute_metrics):
13049 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13050 instead of calling the "wide" APIs directly.
13052 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13054 * w32.h (syms_of_w32font): Add prototype.
13056 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13058 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13059 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13060 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13061 (Fmove_to_window_line): Doc fix.
13063 2011-10-27 Chong Yidong <cyd@gnu.org>
13065 * process.c (make_process): Set gnutls_state to NULL.
13067 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13068 non-NULL, regardless of GNUTLS_INITSTAGE.
13069 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13070 an error. Set process slots as soon as we allocate them.
13072 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13074 2011-10-27 Chong Yidong <cyd@gnu.org>
13076 * gnutls.c (emacs_gnutls_deinit): New function.
13077 Deallocate credentials structures as well as calling gnutls_deinit.
13078 (Fgnutls_deinit, Fgnutls_boot): Use it.
13080 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13081 (deactivate_process): Call emacs_gnutls_deinit.
13083 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13085 * image.c (x_create_x_image_and_pixmap):
13086 * w32.c (sys_rename, w32_delayed_load):
13087 * w32font.c (fill_in_logfont):
13088 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13090 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13092 * w32fns.c (w32_default_color_map): New function,
13093 extracted from Fw32_default_color_map.
13094 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13096 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13098 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13100 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13102 * keyboard.c (test_undefined): New function (bug#9751).
13103 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13105 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13107 * sysdep.c (init_sys_modes): Fix the check for the controlling
13108 terminal (Bug#6649).
13110 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13112 * dispextern.h (struct bidi_it): New member next_en_type.
13114 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13115 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13116 current character, check also for next_en_type being WEAK_EN.
13117 (bidi_resolve_weak): Don't enter the expensive loop if the current
13118 position is before next_en_pos. Record the bidi type of the first
13119 non-ET, non-BN character we find, in addition to its position.
13120 (bidi_level_of_next_char): Invalidate next_en_type when
13121 next_en_pos is over-stepped.
13123 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13125 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13126 * editfns.c: Rewrite current-time-zone so that it invokes
13127 the equivalent of (format-time-string "%Z") to get the time zone name.
13128 This fixes a bug when the time zone name contains characters that
13129 need converting from the system time locale to Emacs internal format.
13130 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13131 that patch fixed format-time-string to do the conversion, but
13132 I forgot to fix current-time-zone.
13133 (format_time_string): New function, containing most of
13134 what Fformat_time_string used to contain.
13135 (Fformat_time_string): Rewrite in terms of format_time_string.
13136 This doesn't change this function's behavior.
13137 (current-time-zone): Rewrite to use format_time_string.
13138 This fixes the bug reported by Michael Schierl in
13139 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13140 Jason Rumney's 2007-06-07 change worked around this bug, but
13142 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13144 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13146 * xdisp.c (start_display): If the character at POS is displayed
13147 via a display vector, reset IT->current.dpvec_index to zero.
13148 (try_window_reusing_current_matrix): If a line ends in a display
13149 vector or the next line starts in a display vector, continue
13150 redrawing the window even though the character position of
13151 start_row was reached.
13154 2011-10-18 Chong Yidong <cyd@gnu.org>
13156 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13157 with nobreak-char-display too.
13159 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13161 Fix part 3 of bug#9771.
13162 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13163 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13164 non-neutral characters if the current character is a paragraph
13165 separator (a.k.a. Newline). This avoids running the same
13166 expensive loop twice, once when we consume the preceding newline
13167 and the other time when the line actually needs to be displayed.
13168 Avoid the loop when we see neutrals on the base embedding level
13169 following a character whose directionality is the same as the
13170 paragraph's. This avoids running the expensive loop when a line
13171 ends in a long sequence of neutrals, like control characters.
13172 Add assertion against STRONG_AL type. Slightly rearrange code
13173 that determines the type of a neutral given the first non-neutral
13175 (bidi_level_of_next_char): Set next_en_pos to zero when
13176 invalidating its info.
13178 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13180 * xdisp.c (push_display_prop): Determine whether to record string
13181 or buffer position by IT->string, not by IT->method. Allow
13182 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13183 (move_it_vertically_backward): Don't look for character position
13184 immediately after the newline when in a continuation line.
13187 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13189 * window.c (coordinates_in_window): Rewrite and delabelize
13190 vertical border check. (Bug#5357) (Bug#9618)
13192 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13194 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13195 errors in XSetWindowBorder (bug#9310).
13197 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13199 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13200 avoid crash when xmalloc overrun checking is enabled.
13202 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13204 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13205 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13206 cursor motion with <left> and <right> arrow keys.
13208 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13209 some callers set that themselves.
13211 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13213 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13214 display string and the previous row comes from the same string and
13215 is empty. (Bug#9739) (Bug#9738)
13217 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13219 * doc.c (get_doc_string): Encode file name (bug#9735).
13221 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13223 * bidi.c (bidi_level_of_next_char):
13224 * xdisp.c (get_visually_first_element): Remove old incorrect
13225 comments regarding the Unicode Line Separator character.
13227 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13229 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13231 * alloc.c (Fgc_status): Do not access beyond zombies array
13232 boundary if nzombies > MAX_ZOMBIES.
13233 * alloc.c (dump_zombies): Add missing format specifier.
13235 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13237 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13238 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13240 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13241 Some packages use them to denote characters with modifiers.
13243 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13245 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13246 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13247 matching a pp-number. Rename parameter var to var1.
13249 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13251 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13253 2011-10-08 Glenn Morris <rgm@gnu.org>
13255 * callint.c (Fcall_interactively): Give a more explicit error for the
13256 'c' case with a non-character input. (Bug#8479)
13258 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13260 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13262 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13263 lines that are hscrolled on the left.
13265 * dispnew.c (buffer_posn_from_coords): Account for a possible
13266 presence of header-line. (Bug#4426)
13268 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13270 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13271 Don't advertise functionality which we discourage or doesn't work.
13273 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13275 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13276 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13277 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13278 this makes Emacs dump core during garbage collection on rare
13279 occasions. sizeof is obviously inferior to offsetof here, so
13280 stick with offsetof.
13281 (GC_POINTER_ALIGNMENT): New macro.
13282 (mark_memory): Omit 3rd (offset) arg; caller changed.
13283 Don't assume EMACS_INT alignment is the same as pointer alignment.
13285 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13287 * keyboard.c (read_key_sequence_remapped): New var.
13288 (read_key_sequence): Compute remapping in the right buffer.
13289 (command_loop_1): Use read_key_sequence's remapping directly.
13291 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13293 * dired.c (file_name_completion): Don't expand file name.
13294 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13295 before checking file name handler.
13297 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13298 they've been requested explicitly (bug#9591).
13300 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13302 * keymap.c (Fsingle_key_description): Use make_specified_string
13303 instead of build_string to build string from push_key_description.
13306 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13308 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13309 This fixes a Y2038 bug on 64-bit hosts.
13310 * buffer.c (reset_buffer):
13311 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13312 (Fclear_buffer_auto_save_failure):
13313 Use 0, not -1, to represent an unset failure time, since time_t
13314 might not be signed.
13316 Remove dependency on glibc malloc internals.
13317 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13318 Move back here from lisp.h, but with their new implementations.
13319 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13320 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13321 * charset.c (charset_table_init): New static var.
13322 (syms_of_charset): Use it instead of xmalloc. This removes a
13323 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13324 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13325 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13326 Move back to alloc.c.
13327 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13328 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13330 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13332 * nsterm.m (windowDidResize): Call x_set_window_size only when
13333 ns_in_resize is true. Otherwise set pixelwidth/height and
13334 call change_frame_size (Bug#9628).
13336 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13338 Port --enable-checking=all to Fedora 14 x86-64.
13339 * charset.c (syms_of_charset): Also account for glibc malloc's
13340 internal overhead when calculating the initial malloc maximum.
13342 Port --enable-checking=all to Fedora 14 x86.
13343 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13345 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13346 (overrun_check_realloc, overrun_check_free):
13347 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13348 That way, xmalloc returns a properly-aligned pointer even if
13349 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13350 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13351 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13352 into account when calculating the initial malloc maximum.
13353 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13354 Move here from alloc.c, so that charset.c can use it too.
13355 Properly align; the old code wasn't right for common 32-bit hosts
13356 when configured with --enable-checking=all.
13357 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13358 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13360 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13362 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13365 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13367 * xdisp.c (compute_display_string_end): If there's no display
13368 string at CHARPOS, return -1.
13370 * bidi.c (bidi_fetch_char): When compute_display_string_end
13371 returns a negative value, treat the character as a normal
13372 character not covered by a display string. (Bug#9624)
13374 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13376 * lread.c (Fread_from_string): Fix typo in docstring.
13378 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13380 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13381 newline, reseat the iterator instead of bidi-iterating there one
13382 character at a time. (Bug#9610)
13383 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13384 TO_CHARPOS if the bidi iterator is at base embedding level.
13386 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13388 * lread.c (readevalloop): Use correct code for NBSP.

13391 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13393 * dbusbind.c (Fdbus_register_signal): When service is not
13394 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13396 2011-09-25 Glenn Morris <rgm@gnu.org>
13398 * buffer.c (truncate-lines): Doc fix.
13400 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13402 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13403 (Fset_window_next_buffers): Doc fix.

13415 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13417 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13418 Default value is now t. Doc fix.
13420 * indent.c (Fvertical_motion): Compute and apply the overshoot
13421 logic when moving up, not only when moving down. Fix the
13422 confusing name and values of the it_overshoot_expected variable;
13423 logic changes accordingly. (Bug#9254) (Bug#9549)
13425 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13426 CHARPOS is covered by a display string which includes newlines.
13427 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13428 is covered by a display string with embedded newlines.
13430 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13432 * dbusbind.c (Fdbus_register_signal): Add match rule to
13433 Vdbus_registered_objects_table. (Bug#9581)
13434 (Fdbus_register_method, Vdbus_registered_objects_table):
13437 2011-09-24 Jim Meyering <meyering@redhat.com>
13439 do not ignore write error for any output size
13440 The previous change was incomplete.
13441 While it makes emacs --batch detect the vast majority of stdout
13442 write failures, errors were still ignored whenever the output size is
13443 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13444 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13445 && echo FAIL: ignored write error
13446 FAIL: ignored write error
13447 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13448 && echo FAIL: ignored write error
13449 FAIL: ignored write error
13450 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13452 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13454 * emacs.c (Fkill_emacs): In noninteractive mode exit
13455 non-successfully if a write error occurred on stdout. (Bug#9574)
13457 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13459 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13462 * dispextern.h (struct it): Update the comment documenting what
13465 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13467 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13468 a display string, extend search for cursor position to end of row.
13469 (find_row_edges): If the row ends in a newline from a display
13470 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13471 Handle the case of a display string with multiple newlines.
13472 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13473 non-empty line. Fixes confusing cursor motion with arrow keys at
13474 the beginning of a line that starts with whitespace.
13476 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13478 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13481 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13483 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13484 boolean (Bug#9154).
13486 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13488 * xdisp.c (display_line): Record maximum and minimum buffer
13489 positions even if no glyphs were produced (e.g., by a zero-width
13490 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13491 buffer positions that will be removed from the glyph row because
13493 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13494 column is beyond frame width: don't subtract 1 "pixel" when
13495 computing width of the stretch.
13496 (reseat_at_next_visible_line_start): Undo the change made on
13497 2011-09-17 that saved paragraph information and restored it after
13498 the call to `reseat'. (Bug#9545)
13500 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13502 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13503 and turn window cursor on if cleared (Bug#9415).
13505 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13507 * search.c (boyer_moore): Take unibyte characters from pattern
13508 literally. (Bug#9458)

13518 initialized, to pacify gcc -Wuninitialized.
13520 * fileio.c: Report proper errno when syscall falls.
13521 (Finsert_file_contents): Save and restore errno,
13522 so that report_file_error outputs the correct diagnostic.
13523 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13525 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13527 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13529 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13531 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13532 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13534 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13536 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13537 about the current paragraph and restore it after the call to reseat.
13539 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13540 (bidi_find_paragraph_start): Search back for paragraph beginning
13541 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13542 (bidi_move_to_visually_next): Only trigger paragraph-related
13543 computations when the last character is a newline or at EOB, not
13544 just any NEUTRAL_B. (Bug#9470)
13546 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13547 truncated lines if point is covered by a display string. (Bug#9524)
13549 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13551 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13552 (cons_to_x_long): New function.
13553 (lisp_data_to_selection_data): Use it. Correct the test for
13554 short-versus-long data; it was negated. Break out of vector
13555 loop, for efficiency, when a long datum is discovered.
13557 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13559 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13561 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13563 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13564 GCC PR/17406) by declaring this function with external scope.
13566 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13568 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13569 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13571 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13573 * editfns.c (Fformat): Correctly handle text properties on "%%".

13583 of TAB characters in a composition.
13585 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13587 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13588 This occurs when processing a multibyte format.
13589 Problem reported by Wolfgang Jenker.
13591 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13593 * xdisp.c (try_cursor_movement): Only check for exact match if
13594 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13596 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13598 Remove unused external symbols.
13599 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13600 * xdisp.c (calc_pixel_width_or_height): Now static.
13601 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13602 * indent.c (check_display_width):
13603 * w32term.c: Fix comment to match code.
13604 * xterm.c, xterm.h (x_catching_errors): Remove.
13606 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13608 * xselect.c: Use signed conversions more consistently (Bug#9498).
13609 (selection_data_to_lisp_data): Assume incoming selection data are
13610 signed integers, not unsigned. This is to be consistent with
13611 outgoing selection data, which was modified to use signed integers
13612 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13613 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13614 expects long, not unsigned long.
13616 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13618 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13619 computation of loop end. Reported by Johan Bockgård
13622 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13624 * frame.c (Fother_visible_frames_p): Function deleted.
13626 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13628 * indent.c (compute_motion): Process display vector front to back
13629 rather than the other way around. (Bug#2496)
13631 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13633 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13635 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13637 * minibuf.c (Fread_from_minibuffer): Doc fix.
13639 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13641 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13642 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13644 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13646 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13647 value for non-existent files.
13649 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13651 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13652 set its "size" to -1. This will set the modtime_size field of
13653 the corresponding buffer to -1, which is what
13654 verify-visited-file-modtime expects for files that do not exist.
13657 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13659 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13661 * lisp.h: ... from here. push_key_description is no longer
13662 defined in keyboard.c, so its declaration should not be in
13663 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13664 logically belongs with push_key_description.
13666 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13668 * buffer.h: Include <sys/types.h> instead of <time.h>.
13669 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13670 Problem reported by Herbert J. Skuhra.
13672 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13674 * xml.c (parse_region): Make the parsing work for
13675 non-comment-starting XML files again (bug#9144).
13677 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13679 * image.c (gif_load): Fix calculation of bottom and right corner.
13682 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13684 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13685 redisplay in small windows.
13687 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13689 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13691 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13693 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13694 Operate on live windows only.
13696 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13698 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13700 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13702 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13703 only under bidi iteration.
13705 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13707 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13709 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13711 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13712 Without this fix, the command to link temacs failed due to an
13713 undefined symbol __builtin_isnan. This is because
13714 /usr/include/iso/math_c99.h #defines isnan(x) to
13715 __builtin_isnan(x), but the bundled gcc, which identifies itself
13716 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13718 * floatfns.c (isnan): #undef, and then #define to a clone of
13720 (Fisnan): Always define, since it's always available now.
13721 (syms_of_floatfns): Always define isnan at the Lisp level.
13723 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13725 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13727 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13729 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13730 The previous code assumed that file offsets (off_t values) fit in
13731 EMACS_INT variables, which is not true on typical 32-bit hosts.
13732 The code messed up by falsely reporting buffer overflow in cases
13733 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13734 when "big" contains more than 2**29 bytes, even though this
13735 inserts just one byte and does not overflow the buffer.
13736 (Finsert_file_contents): Store file offsets as off_t
13737 values, not as EMACS_INT values. Check for overflow when
13738 converting between EMACS_INT and off_t. When checking for
13739 buffer overflow or for overlap, take the offsets into account.
13740 Don't use EMACS_INT for small values where int suffices.
13741 When checking for overlap, fix a typo: ZV was used where
13742 ZV_BYTE was intended.
13743 (Fwrite_region): Don't assume off_t fits into 'long'.
13744 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13746 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13748 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13750 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13752 sprintf-related integer and memory overflow issues (Bug#9412).
13754 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13755 (esprintf, exprintf, evxprintf): New functions.
13756 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13757 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13758 (modify_event_symbol): Do not assume that the length of
13759 name_alist_or_stem is safe to alloca and fits in int.
13760 (Fexecute_extended_command): Likewise for function name and binding.
13761 (Frecursion_depth): Wrap around reliably on integer overflow.
13762 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13763 since some callers pass EMACS_INT values.
13764 (Fsingle_key_description): Don't crash if symbol name contains more
13765 than MAX_ALLOCA bytes.
13766 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13767 (get_minibuffer): Arg is now EMACS_INT, not int.
13768 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13769 (esprintf, exprintf, evxprintf): New decls.
13770 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13772 * dbusbind.c (signature_cat): New function.
13773 (xd_signature, Fdbus_register_signal):
13774 Do not overrun buffer; instead, report string overflow.
13776 * dispnew.c (add_window_display_history): Don't overrun buffer.
13777 Truncate instead; this is OK since it's just a log.
13779 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13780 even if the time zone offset is outlandishly large.
13781 Don't mishandle offset == INT_MIN.
13783 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13784 when creating daemon; the previous buffer-overflow check was incorrect.
13786 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13787 which has the guts of the old verror function.
13789 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13790 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13792 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13793 (font_unparse_xlfd): Don't blindly alloca long strings.
13794 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13795 fits in int, when using sprintf. Use single snprintf to count
13796 length of string rather than counting it via multiple sprintfs;
13797 that's simpler and more reliable.
13798 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13799 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13800 sprintf, in case result does not fit in int.
13802 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13803 (fontset_from_font): Print it.
13805 * frame.c (tty_frame_count): Now printmax_t, not int.
13806 (make_terminal_frame, set_term_frame_name): Print it.
13807 (x_report_frame_params): In X, window IDs are unsigned long,
13808 not signed long, so print them as unsigned.
13809 (validate_x_resource_name): Check for implausibly long names,
13810 and don't assume name length fits in 'int'.
13811 (x_get_resource_string): Don't blindly alloca invocation name;
13812 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13815 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13816 (xg_check_special_colors, xg_set_geometry):
13817 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13819 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13820 Use esprintf, not sprintf, in case result does not fit in int.
13822 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13823 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13824 it as a large positive number.
13825 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13826 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13828 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13829 in case result does not fit in int.
13831 * print.c (float_to_string): Detect width overflow more reliably.
13832 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13833 buffer overrun. Don't assume list length fits in 'int'. Treat
13834 print length of 0 as 0, not as infinity; to be consistent with other
13835 uses of print length in this function. Don't overflow print length
13836 index. Don't assume hash table size fits in 'long', or that
13837 vectorlike size fits in 'unsigned long'.
13839 * process.c (make_process): Use printmax_t, not int, to format
13840 process-name gensyms.
13842 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13844 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13845 to avoid potential buffer overrun.
13847 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13848 if X resource line is longer than 512 bytes.
13850 * xfns.c (x_window): Make sprintf buffer a bit bigger
13851 to avoid potential buffer overrun.
13853 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13855 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13857 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13859 Integer overflow fixes for scrolling, etc.
13860 Without these, Emacs silently mishandles large integers sometimes.
13861 For example, "C-u 4294967297 M-x recenter" was treated as if
13862 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13864 * xdisp.c (try_window_id): Check Emacs fixnum range before
13865 converting to 'int'.
13867 * window.c (window_scroll_line_based, Frecenter):
13868 Check that an Emacs fixnum is in range before assigning it to 'int'.
13869 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13870 values converted from Emacs fixnums.
13871 (Frecenter): Don't wrap around a line count if it is out of 'int'
13872 range; instead, treat it as an extreme value.
13873 (Fset_window_configuration, compare_window_configurations):
13874 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13876 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13877 that can exceed INT_MAX. Check that EMACS_INT value is in range
13878 before assigning it to the (possibly-narrower) index.
13879 (match_limit): Don't assume that a fixnum can fit in 'int'.
13881 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13884 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13885 (Fvertical_motion): Don't wrap around LINES values that don't fit
13886 in 'int'. Instead, treat them as extreme values. This is good
13887 enough for windows, which can't have more than INT_MAX lines anyway.
13889 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13891 * Require libxml/parser.h to avoid compilation warning.
13893 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13895 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13896 since this reportedly can destroy thread storage.
13898 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13900 * syntax.c (find_defun_start): Update all cache variables if
13901 exiting early (Bug#9401).
13903 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13905 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13907 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13908 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13909 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13911 * term.c (tty_append_glyph): New function.
13912 (produce_stretch_glyph): Static function and its prototype deleted.
13914 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13917 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13919 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13920 when checking :margin (Bug#9390).
13921 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13922 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13923 so that the name doesn't mislead. All uses changed.
13925 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13927 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13930 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13932 * xdisp.c (move_it_to): Don't bail out early when reaching
13933 position beyond to_charpos, if we are scanning backwards.
13934 (move_it_vertically_backward): When DY == 0, make sure we get to
13935 the first character in the line after the newline.
13937 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13939 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13940 (ccl_driver): Do not generate an out-of-range pointer.
13941 (Fccl_execute_on_string): Remove unnecessary check for
13942 integer overflow, noted by Stefan Monnier in
13943 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13944 Remove a FIXME that didn't need fixing.
13945 Simplify the newly-introduced buffer reallocation code.
13947 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13949 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13951 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13953 Integer and memory overflow issues (Bug#9196).
13955 * doc.c (get_doc_string): Rework so that
13956 get_doc_string_buffer_size is the actual buffer size, rather than
13957 being 1 less than the actual buffer size; this makes xpalloc more
13960 * image.c (x_allocate_bitmap_record, cache_image):
13961 * xselect.c (Fx_register_dnd_atom):
13962 Simplify previous changes by using xpalloc.
13964 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13965 since either will do and ptrdiff_t is convenient with xpalloc.
13967 * charset.c (charset_table_size)
13968 (struct charset_sort_data.priority): Now ptrdiff_t.
13969 (charset_compare): Don't overflow if priorities differ greatly.
13970 (Fsort_charsets): Don't assume list length fits in int.
13971 Check for size-calculation overflow when allocating sort data.
13972 (syms_of_charset): Allocate an initial charset table that is
13973 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13975 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13977 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13978 The actual value is always <= INT_MAX, and leaving it unsigned made
13979 overflow checking harder.
13981 * dispextern.h (struct glyph_matrix.rows_allocated)
13982 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13983 with xpalloc. The values are still always <= INT_MAX.
13985 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13987 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13988 (SAFE_NALLOCA): New macro.
13990 * region-cache.c (struct boundary.pos, find_cache_boundary)
13991 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13992 (set_cache_region, invalidate_region_cache)
13993 (revalidate_region_cache, know_region_cache, region_cache_forward)
13994 (region_cache_backward, pp_cache):
13995 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13996 so that ptrdiff_t * can be passed to xpalloc.
13997 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13998 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13999 (pp_cache): Don't assume cache_len fits in int.
14000 * region-cache.h: Adjust extern decls to match.
14002 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14003 EMACS_INT, since either will do, for xpalloc.
14005 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14006 (xnmalloc, xnrealloc, xpalloc): New functions.
14008 * bidi.c (bidi_shelve_header_size): New constant.
14009 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14010 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14012 * bidi.c (bidi_cache_shrink):
14013 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14015 Don't update size of array until after memory allocation succeeds,
14016 because xmalloc/xrealloc may not return.
14017 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14018 now that we have proper integer overflow checking.
14019 (record_overlay_string, overlay_strings): Catch overflows when
14020 calculating size of overlay_str_buf.
14022 * callproc.c (Fcall_process): Check for size overflow when
14023 calculating size of args2.
14024 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14025 Normally we prefer signed values, but sticking with ptrdiff_t would
14026 require adding more-complicated checks.
14028 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14029 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14030 Redo buffer-overflow calculations to avoid integer overflow.
14031 Add a FIXME comment where memory seems to be over-allocated.
14033 * character.c (Fstring): Check for size-calculation overflow.
14035 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14036 unnecessary integer overflow. Check for size overflow.
14037 (encode_coding_object): Don't update size until xmalloc succeeds.
14039 * composite.c (get_composition_id): Check for overflow in glyph
14040 length calculations.
14042 Integer and memory overflow fixes for display code.
14043 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14044 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14045 (scrolling_window): Check for overflow in size calculations.

14049 (row_table_size): Now ptrdiff_t, not int.
14050 (scrolling_window): Avoid overflow in size calculations.
14051 Don't update size until allocation succeeds.
14052 * fns.c (concat): Check for overflow in size calculations.
14053 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14054 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

14057 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14058 (get_doc_string): Check for size calculation overflow.
14059 Don't update size until allocation succeeds.
14060 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14061 EMACS_INT, where ptrdiff_t will do.
14062 (Fsubstitute_command_keys): Check for string overflow.
14064 * editfns.c (set_time_zone_rule): Don't assume environment length
14066 (message_length): Now ptrdiff_t, not int.
14067 (Fmessage_box): Don't update size until allocation succeeds.
14068 Don't assume message length fits in int.
14069 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14071 * emacs.c (main): Do not reallocate argv, since there is a null at
14072 the end that can be overwritten, and this way there's no need to
14073 worry about size-calculation overflow.
14074 (sort_args): Check for size-calculation overflow.
14076 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14078 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14080 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14081 (x_set_scroll_bar_width, x_figure_window_size):
14082 Check for integer overflow.
14083 (x_set_alpha): Do not assume XINT fits in int.
14085 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14086 This is for the members text_lines, text_cols, total_lines, total_cols,
14087 where the system imposes an 'int' limit.
14089 * fringe.c (Fdefine_fringe_bitmap):
14090 Don't update size until alloc works.
14092 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14093 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14095 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14096 Check for size-calculation overflow.
14097 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14098 do, as we prefer signed integers.
14099 (id_to_widget.max_size, id_to_widget.used)
14100 (xg_store_widget_in_map, xg_remove_widget_from_map)
14101 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14102 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14103 Use and return ptrdiff_t, not int.
14104 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14105 * gtkutil.h: Change prototypes to match the above.
14107 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14108 are duplicate now that they've been promoted to lisp.h.
14109 (x_allocate_bitmap_record, x_alloc_image_color)
14110 (make_image_cache, cache_image, xpm_load):
14111 Don't update size until alloc is done.
14112 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
14114 Check for size calculation overflow.
14115 (ct_colors_allocated_max): New constant.
14116 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

14122 Use ptrdiff_t, not int, to count maps.
14123 (read_char_minibuf_menu_prompt): Check for overflow in size
14124 calculations. Don't update size until allocation succeeds.
14125 Redo calculations to avoid overflow.
14126 * keyboard.h: Change prototypes to match the above.
14128 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14130 (current_minor_maps): Check for size calculation overflow.
14131 * keymap.h: Change prototypes to match the above.
14133 * lread.c (read1, init_obarray): Don't update size until alloc done.
14135 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
14136 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
14138 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
14139 Now ptrdiff_t, not int.
14140 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

14152 (Fset_match_data): Don't assume list lengths fit in 'int'.
14154 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14155 for command line length. Do not attempt to address one before the
14156 beginning of an array, as that's not portable.
14158 * term.c (max_frame_lines): Remove; unused.
14159 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14161 (encode_terminal_code, calculate_costs): Check for size
14162 calculation overflow.

14165 done. Redo calculations to avoid overflow.
14166 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
14168 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14169 subtracting pointers.
14170 (gobble_line): Check for overflow more carefully. Don't update size
14173 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

14184 Use ptrdiff_t, not int, for sizes.
14185 (Finternal_make_lisp_face, cache_face):
14186 Check for size calculation overflow.
14187 (cache_face): Treat size calculation overflows as if they were
14188 memory exhaustion (the usual treatment), rather than aborting.
14190 * xfns.c (x_encode_text, x_set_name_internal)
14191 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14192 sizes, since they can exceed INT_MAX in size. Check for size
14193 calculation overflow.
14195 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14196 (xg_select): Check for size calculation overflow.
14197 Don't update size until alloc done.
14199 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14200 as sprintf is limited to int lengths.
14202 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14203 (X_LONG_MIN): New macros.
14204 Use them to make the following changes clearer.
14205 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14206 This change doesn't affect the value now, but it may help remind
14207 future maintainers not to raise the value too much later.
14208 (SELECTION_QUANTUM): Remove, replacing with ...
14209 (selection_quantum): ... new function, which avoids overflow.
14211 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14212 assumption that selection length fits in 'int'.
14213 (x_reply_selection_request, x_handle_selection_request)
14214 (x_get_window_property, receive_incremental_selection)
14215 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
14216 (lisp_data_to_selection_data, clean_local_selection_data):

14218 (x_reply_selection_request, x_get_window_property)
14219 (receive_incremental_selection, x_property_data_to_lisp):
14220 Redo calculations to avoid overflow.
14221 (x_reply_selection_request): When sending hint, ceiling it at
14222 X_LONG_MAX rather than relying on wraparound overflow to send
14224 (x_get_window_property, receive_incremental_selection)
14225 (lisp_data_to_selection_data, x_property_data_to_lisp):
14226 Check for size-calculation overflow.
14227 (x_get_window_property, receive_incremental_selection)
14228 (lisp_data_to_selection_data, Fx_register_dnd_atom):
14229 Don't store size until memory allocation succeeds.
14230 (x_get_window_property): Plug memory leak on memory exhaustion.
14231 Don't double-block input; malloc is safe here. Don't assume 2**34
14232 - 4 fits in unsigned long. Add an xassert to check
14233 XGetWindowProperty overflow. Be more careful about overflow
14234 calculations, and distinguish size from memory overflow better.
14235 (receive_incremental_selection): When tracing, don't assume
14236 unsigned int is less than INT_MAX.
14237 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14238 harmful) conversions of unsigned short to int.
14239 (lisp_data_to_selection_data): Don't assume that integers
14240 in the range -65535 through -1 fit in an X unsigned short.
14241 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14242 result parameters unless successful. Rely on cons_to_unsigned
14243 to report problems with elements; the old code wasn't right anyway.
14244 (x_check_property_data): Check for int overflow; we cannot use
14245 a wider type due to X limits.
14246 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
14248 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
14250 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
14251 (x_term_init): Check for size calculation overflow.
14252 (x_color_cells): Don't store size until memory allocation succeeds.

14277 * image.c (xpm_get_color_table_h):
14278 * lisp.h (hash_lookup, hash_put):
14279 * minibuf.c (Ftest_completion):
14280 Use ptrdiff_t for hash table indexes, not int (which is too
14281 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14282 32-bit --with-wide-int hosts).
14284 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14285 Add a FIXME comment about memory leaks.
14286 (syms_of_charset): Don't assume xmalloc returns.
14288 Don't assume that stated character widths fit in int.
14289 * character.c (Fchar_width, c_string_width, lisp_string_width):
14290 * character.h (CHAR_WIDTH):
14291 * indent.c (MULTIBYTE_BYTES_WIDTH):
14292 Use sanitize_char_width to avoid undefined and/or bad behavior
14293 with outlandish widths.
14294 * character.h (sanitize_tab_width): Rename from sanitize_width,
14295 now that we have two such functions. All uses changed.
14296 (sanitize_char_width): New inline function.
14298 Don't assume that tab-width fits in int.
14299 * character.h (sanitize_width): New inline function.
14300 (SANE_TAB_WIDTH): New macro.
14301 (ASCII_CHAR_WIDTH): Use it.

14306 * fileio.c: Integer overflow issues with file modes.
14307 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
14309 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
14310 Remove unreachable code.
14311 (read_hex, load_charset_map_from_file): Check for integer overflow.
14313 * xterm.c: Don't go over XClientMessageEvent limit.
14314 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14315 (x_send_scroll_bar_event): Likewise. Check that the size does not
14316 exceed limits imposed by XClientMessageEvent, as well as the usual
14317 ptrdiff_t and size_t limits.
14319 * keyboard.c: Overflow, signedness and related fixes.
14320 (make_lispy_movement): Use same integer type in forward decl
14321 that is used in the definition.
14322 (read_key_sequence, keyremap_step):
14323 Change bufsize argument back to int, undoing my 2011-03-30 change.
14324 We prefer signed types, and int is wide enough here.
14325 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14326 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14327 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14328 length, not size_t. Use ptrdiff_t for index, not int.
14329 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14330 possibility of integer overflow.
14332 Overflow, signedness and related fixes for images.
14334 * dispextern.h (struct it.stack[0].u.image.image_id)
14335 (struct_it.image_id, struct image.id, struct image_cache.size)

14342 * xdisp.c (calc_pixel_width_or_height):
14343 * xfns.c (image_cache_refcount):
14344 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
14345 on typical 64-bit hosts.

14351 when the callers expect that.
14352 (image_ascent): Redo ascent calculation to avoid int overflow.
14353 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14354 (lookup_image): Remove unnecessary tests.
14355 (xbm_image_p): Locals are now of int, not EMACS_INT,
14356 since parse_image_check makes sure they fit into int.
14357 (png_load, gif_load, svg_load_image):
14358 Prefer int to unsigned where either will do.
14359 (tiff_handler): New function, combining the cores of the
14360 old tiff_error_handler and tiff_warning_handler.
14361 This function is rewritten to use vsnprintf and thereby avoid
14362 stack buffer overflows. It uses only the features of vsnprintf
14363 that are common to both POSIX and native Microsoft.
14364 (tiff_error_handler, tiff_warning_handler): Use it.
14365 (tiff_load, gif_load, imagemagick_load_image):
14366 Don't assume :index value fits in 'int'.
14367 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14368 (imagemagick_load_image): Check that crop parameters fit into
14369 the integer types that MagickCropImage accepts. Don't assume
14370 Vimagemagick_render_type has a nonnegative value. Don't assume
14371 size_t fits in 'long'.
14372 (gs_load): Use printmax_t to print the widest integers possible.
14373 Check for integer overflow when computing image height and width.

14385 handle_single_display_spec, not just 1 or zero.
14386 (handle_single_display_spec): If the display spec is of the form
14387 `(space ...)', and specifies display in the text area, return 2
14389 (try_cursor_movement): Check for the need to scroll more
14390 accurately, and prefer exact match for point under bidi.
14391 Don't advance `row' beyond the last row of the window.
14393 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
14394 into disp_prop; all users changed.
14396 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
14397 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
14398 for the text covered by the display property.

14408 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14409 buffers, return left-to-right.
14410 (set_cursor_from_row): Consider candidate row a win if its glyph
14411 represents a newline and point is on that newline. Fixes cursor
14412 positioning on the newline at EOL of R2L text within L2R
14413 paragraph, and vice versa.
14414 (try_cursor_movement): Check continued rows, in addition to
14415 continuation rows. Fixes unwarranted scroll when point enters a
14416 continued line of R2L text within an L2R paragraph, or vice versa.
14417 (cursor_row_p): Consider the case of point being equal to
14418 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14419 from the end of a short line to the beginning of a continued line
14420 of R2L text within L2R paragraph.
14421 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
14422 composed characters.
14424 * bidi.c (bidi_check_type): Use xassert.

14435 * nsfont.m (ns_otf_to_script): Fix typo.
14437 2011-08-22 Kenichi Handa <handa@m17n.org>
14439 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
14440 extra slot even if the purpose is char-code-property-table.
14442 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14444 * xdisp.c (redisplay_window): When computing centering_position,
14445 account for the height of the header line. (Bug#8874)
14447 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14448 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14449 candidate is selected by the mouse, and that candidate has a
14450 composed character under the mouse.
14452 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14453 coordinates reported by pos-visible-in-window-p for a composed
14454 character in column zero.
14456 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
14458 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
14460 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14462 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14463 consider it a hit if to_charpos is anywhere in the range of the
14464 composed buffer positions.
14466 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14468 * image.c (gif_load): Don't assume that each subimage has the same
14469 dimensions as the base image. Handle disposal method that is
14470 "undefined" by the gif spec (Bug#9335).
14472 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14474 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14477 2011-08-19 Eli Zaretskii <eliz@gnu.org>
14479 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14480 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14481 from an Org mode buffer to a Speedbar frame.
14483 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14484 a composition, take its buffer position from IT->cmp_it.charpos.
14485 Fixes cursor positioning at the beginning of a line that begins
14486 with a composed character.
14488 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14490 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14491 character bidirectional type, use STRONG_L instead. Fixes crashes
14492 in a buffer produced by `describe-categories'.
14494 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14495 members before the level stack, so they would be saved and
14496 restored when copying iterator state. Fixes incorrect reordering
14497 around TABs covered by display properties.
14499 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

14507 Remove unnecessary aborts (Bug#9081).
14509 2011-08-17 Eli Zaretskii <eliz@gnu.org>
14511 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
14512 has no `load' handler, try opening the file locally. (Bug#9311)
14514 2011-08-16 Ken Brown <kbrown@cornell.edu>
14516 * gmalloc.c: Expand comment.
14518 2011-08-16 Eli Zaretskii <eliz@gnu.org>
14520 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate

14571 * xdisp.c (move_it_in_display_line_to): Don't invoke
14572 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14573 ppos_it. Fixes vertical cursor motion when line beginning is
14574 covered by an image. (Bug#9296)
14576 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14578 * nsterm.h (ns_run_ascript): Declare.

14582 (ns_run_ascript): New function.
14583 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14584 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14585 the event loop. Get status from as_status (Bug#7276).
14587 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14588 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14589 the event loop (Bug#7276).
14591 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

14615 (Fnetwork_interface_list): Allocate in increments of bytes instead
14616 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14617 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14619 (struct ifflag_def): notrailers is smart on OSX.
14620 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14621 Get hardware address with getifaddrs if available.
14623 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14625 * xdisp.c (iterate_out_of_display_property): xassert that
14626 IT->position is set to within IT->object's boundaries. Break from
14627 the loop as soon as EOB is reached; avoids infloops in redisplay

14629 Set IT->current to match the bidi iterator unconditionally.
14630 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14631 entry. Force push_it to save on the stack the current
14632 buffer/string position, to be restored by pop_it. Fix flags in
14633 the iterator structure wrt the object coming from a display
14634 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14635 properties. (Bug#9284)
14637 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14639 * fontset.c (fontset_get_font_group): Add proper type checks.

14652 no-display-properties-and-no-overlays under bidi display.
14653 Set disp_pos in the bidi iterator to avoid searches for display
14654 properties and overlays.
14656 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14658 * editfns.c (Fset_time_zone_rule): Document relationship with the

14667 restore_point_unwind (Bug#5984).
14669 2011-08-07 Juri Linkov <juri@jurta.org>
14671 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14672 to show the arg `TIME' instead of `TIMEVAL'.
14674 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14676 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14677 display property strides EOL and includes a newline, as in
14678 longlines-mode. (Bug#9254)
14679 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14680 word-wrap under bidirectional display. (Bug#9224)
14682 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14683 is non-zero, even if the data buffer is NULL. Fixes a crash in
14684 vertical-motion with longlines-mode. (Bug#9254)
14686 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14688 * bidi.c <bidi_cache_total_alloc>: Now static.

14691 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14694 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14695 amount allocated this far in `bidi_cache_total_alloc'.
14696 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14697 non-zero, only free the data buffer without restoring the cache
14698 contents. All callers changed.
14700 * dispextern.h (bidi_unshelve_cache): Update prototype.
14702 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14703 (move_it_in_display_line, move_it_to)
14704 (move_it_vertically_backward, move_it_by_lines): Replace the call
14705 to xfree to an equivalent call to bidi_unshelve_cache.
14706 (move_it_in_display_line_to): Fix logic of returning
14707 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14709 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14711 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14712 came from a string character with a `cursor' property. (Bug#9229)

14742 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14744 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14745 so that it is not optimized away.
14747 * xdisp.c (compute_display_string_pos): Remove unused local.
14749 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14751 Fix slow cursor motion and scrolling in large buffers with
14752 selective display, like Org Mode buffers. (Bug#9218)
14754 * dispextern.h (struct bidi_it): New member disp_prop_p.
14756 * xdisp.c: Remove one-slot cache of display string positions.
14757 (compute_display_string_pos): Accept an additional argument
14758 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14759 for a display string or property. If found, set DISP_PROP_P
14762 * bidi.c (bidi_fetch_char): Accept an additional argument
14763 DISP_PROP_P, and pass it to compute_display_string_pos.
14764 Only handle text covered by a display string if DISP_PROP_P is returned
14765 non-zero. All callers of bidi_fetch_char changed.
14767 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14769 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14771 2010-12-03 Don March <don@ohspite.net>
14773 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14774 last character M-[char] is translated to ESC [char] (bug#7541).
14776 2011-08-02 Kenichi Handa <handa@m17n.org>
14778 * lisp.h (uniprop_table): Extern it.
14780 * chartab.c (uniprop_table): Make it non-static.
14782 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14784 * xdisp.c (forward_to_next_line_start): Accept additional argument
14785 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14787 (reseat_at_next_visible_line_start): Use the bidi iterator state
14788 returned by forward_to_next_line_start to restore the state of
14789 it->bidi_it after backing up to previous newline. (Bug#9212)
14791 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14793 * regex.c (re_comp): Protoize.
14794 (re_exec): Fix return type.
14795 (regexec): Fix type of `ret'. (Bug#9203)
14797 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14799 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14800 This is needed if max-image-size is a floating-point number.
14802 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14804 * print.c (print_object): Print empty symbol as ##.
14806 * lread.c (read1): Read ## as empty symbol.
14808 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14810 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14811 setting frame foreground color (Bug#9175).
14812 (x_set_background_color): Likewise.
14814 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14815 contents (Bug#9176).
14816 (EmacsTooltip -init): Remove bezels and add shadows to
14819 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14820 or scroll bar (Bug#8470).
14822 * nsfont.m (nsfont_open): Remove assignment to voffset and
14823 unnecessary vars hshink, expand, hd, full_height, min_height.
14824 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14826 * nsterm.h (nsfont_info): Remove voffset field.
14828 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14830 Implement strike-through and overline on NextStep (Bug#8863).
14832 * nsfont.m (nsfont_open): Use underline position provided by font,
14833 instead of hard-coded value of 2.
14834 (nsfont_draw): Call ns_draw_text_decoration instead.
14836 * nsterm.h: Add declaration for ns_draw_text_decoration.
14838 * nsterm.m (ns_draw_text_decoration): New function for drawing
14839 underline, overline, and strike-through.
14840 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14841 ns_draw_text_decoration. Change treatment of cursor drawing to
14842 accommodate underlining, etc.
14844 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14846 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14849 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14851 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14852 Without this fix, if a signal arrives just after memory fills up,
14853 'malloc' might be invoked reentrantly.
14855 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14856 In other words, assume that every image size is allowed, on non-X
14857 hosts. This assumption is probably wrong, but it lets Emacs compile.
14859 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14861 * regex.c (re_iswctype): Convert return values to boolean.
14863 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14865 * xdisp.c (compute_display_string_pos): Don't use cached display
14866 string position if the buffer had its restriction changed.
14869 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14871 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14873 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14875 Integer signedness and overflow and related fixes. (Bug#9079)
14877 * bidi.c: Integer size and overflow fixes.
14878 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14879 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14880 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14881 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14882 (bidi_find_other_level_edge):
14883 Use ptrdiff_t instead of EMACS_INT where either will do.
14884 This works better on 32-bit hosts configured --with-wide-int.
14885 (bidi_cache_ensure_space): Check for size-calculation overflow.
14886 Use % rather than repeated addition, for better worst-case speed.
14887 Don't set bidi_cache_size until after xrealloc returns, because it
14889 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14890 (bidi_cache_ensure_space): Also check that the bidi cache size
14891 does not exceed that of the largest Lisp string or buffer. See Eli
14892 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14894 * alloc.c (__malloc_size_t): Remove.
14895 All uses replaced by size_t. See Andreas Schwab's note
14896 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14898 * image.c: Improve checking for integer overflow.
14899 (check_image_size): Assume that f is nonnull, since
14900 it is always nonnull in practice. This is one less thing to
14901 worry about when checking for integer overflow later.
14902 (x_check_image_size): New function, which checks for integer
14903 overflow issues inside X.
14904 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14905 This removes the need for a memory_full check.
14906 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14907 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14908 (xbm_read_bitmap_data): Change locals back to 'int', since
14909 their values must fit in 'int'.
14910 (xpm_load_image, png_load, tiff_load):
14911 Invoke x_create_x_image_and_pixmap earlier,
14912 to avoid much needless work if the image is too large.
14913 (tiff_load): Treat overly large images as if
14914 x_create_x_image_and_pixmap failed, not as malloc failures.
14915 (gs_load): Use x_check_image_size.
14917 * gtkutil.c: Omit integer casts.
14918 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14919 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14921 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14923 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14924 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14925 would wrongly return t on a 64-bit host.
14927 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14928 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14929 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14930 and therefore cause GCC to emit a bogus diagnostic in some cases.
14932 * image.c: Integer signedness and overflow and related fixes.
14933 This is not an exhaustive set of fixes, but it's time to
14934 record what I've got.
14935 (lookup_pixel_color, check_image_size): Remove redundant decls.
14936 (check_image_size): Don't assume that arbitrary EMACS_INT values
14937 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14938 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14939 (tiff_load, imagemagick_load_image):
14940 Check for overflow in size calculations.
14941 (x_create_x_image_and_pixmap): Remove unnecessary test for
14942 xmalloc returning NULL; that can't happen.
14943 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14944 (xpm_color_bucket): Use better integer hashing function.
14945 (xpm_cache_color): Don't possibly over-allocate memory.
14946 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14947 (gif_memory_source):
14948 Use ptrdiff_t, not int or size_t, to record sizes.
14949 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14950 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14951 either works, as we prefer signed integers.
14952 (tiff_read_from_memory, tiff_write_from_memory):
14953 Return tsize_t, not size_t, since that's what the TIFF API wants.
14954 (tiff_read_from_memory): Don't fail simply because the read would
14955 go past EOF; instead, return a short read.
14956 (tiff_load): Omit no-longer-needed casts.
14957 (Fimagemagick_types): Don't assume size fits into 'int'.
14959 Improve hashing quality when configured --with-wide-int.
14960 * fns.c (hash_string): New function, taken from sxhash_string.
14961 Do not discard information about ASCII character case; this
14962 discarding is no longer needed.
14963 (sxhash-string): Use it. Change sig to match it. Caller changed.
14964 * lisp.h: Declare it.
14965 * lread.c (hash_string): Remove, since we now use fns.c's version.
14966 The fns.c version returns a wider integer if --with-wide-int is
14967 specified, so this should help the quality of the hashing a bit.
14969 * emacs.c: Integer overflow minor fix.
14970 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14971 Define only if GNU_LINUX.
14972 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14974 * dispnew.c: Integer signedness and overflow fixes.
14975 Remove unnecessary forward decls, that were a maintenance hassle.
14976 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14978 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14979 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14980 (prepare_desired_row, line_draw_cost):
14981 Use int, not unsigned, where either works.
14982 (save_current_matrix, restore_current_matrix):
14983 Use ptrdiff_t, not size_t, where either works.
14984 (init_display): Check for overflow more accurately, and without
14985 relying on undefined behavior.
14987 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14988 Remove, replacing with the new symbols in lisp.h. All uses changed.
14989 * fileio.c (make_temp_name):
14990 * filelock.c (lock_file_1, lock_file):
14991 * xdisp.c (message_dolog):
14992 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14993 Use pMd etc. instead.
14994 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14995 replacing the pWIDE etc. symbols removed from editfns.c.
14997 * keyboard.h (num_input_events): Now uintmax_t.
14998 This is (very slightly) less likely to mess up due to wraparound.
15001 * buffer.c: Integer signedness fixes.
15002 (alloc_buffer_text, enlarge_buffer_text):
15003 Use ptrdiff_t rather than size_t when either will do, as we prefer
15006 * alloc.c: Integer signedness and overflow fixes.
15007 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15008 (__malloc_size_t): Default to size_t, not to int.
15009 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15010 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15011 Prefer ptrdiff_t to size_t when either would do, as we prefer
15013 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15014 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15015 Now const. Initialize with values that are in range even if char
15017 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15018 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15019 These functions do the right thing with sizes > 2**32.
15020 (check_depth): Now ptrdiff_t, not int.
15021 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15022 Adjust to new way of storing sizes. Check for size overflow bugs
15024 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15025 slightly wrong anyway, as it missed one instance of
15026 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15027 (refill_memory_reserve): Omit needless cast to size_t.
15028 (mark_object_loop_halt): Mark as externally visible.
15030 * xselect.c: Integer signedness and overflow fixes.
15031 (Fx_register_dnd_atom, x_handle_dnd_message):
15032 Use ptrdiff_t, not size_t, since we prefer signed.
15033 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15034 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15035 x_dnd_atoms_size and x_dnd_atoms_length.
15037 * doprnt.c: Prefer signed to unsigned when either works.
15039 * doprnt.c (doprnt):
15041 * xdisp.c (vmessage):
15042 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15043 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15044 prefer signed arithmetic to avoid comparison confusion.
15045 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15046 but is a bit tricky.
15048 Assume freestanding C89 headers, string.h, stdlib.h.
15049 * data.c, doprnt.c, floatfns.c, print.c:
15050 Include float.h unconditionally.
15051 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15052 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15053 * regex.c: Likewise for stddef.h, string.h.
15054 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15055 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15056 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15057 (STDC_HEADERS): Remove obsolete defines.
15058 * sysdep.c: Include limits.h unconditionally.
15060 Assume support for memcmp, memcpy, memmove, memset.
15061 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15062 * regex.c (memcmp, memcpy):
15063 Remove; we assume C89 now.
15065 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15066 (__malloc_safe_bcopy): Remove; no longer needed.
15068 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15069 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15070 well either way, and we prefer signed to unsigned.
15072 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15074 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15075 closes the connection while we're reading (bug#9182).
15077 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15079 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15080 are specified (Bug#9168).
15082 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15084 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15085 Found by GCC static checking and --with-wide-int on a 32-bit host.
15087 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15089 * xdisp.c (compute_display_string_pos): Fix logic of caching
15090 previous display string position. Initialize cached_prev_pos to
15091 -1. Fixes slow-down at the beginning of a buffer.
15093 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15095 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15096 for attrs[LFACE_FONTSET_INDEX].
15098 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15100 * xml.c (parse_region): Remove unused local
15101 that was recently introduced.
15103 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15105 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15106 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15108 * xdisp.c (move_it_in_display_line_to): Record the best matching
15109 position for TO_CHARPOS while scanning the line, and restore it on
15110 exit if none of the characters scanned was an exact match.
15111 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15112 when exact match is impossible due to invisible text, and the
15113 lines are truncated.
15115 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15117 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15120 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15122 Fix a significant slow-down of cursor motion with C-n, C-p,
15123 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15124 auto-repeat under bidi redisplay in fontified buffers.
15125 * xdisp.c (compute_stop_pos_backwards): New function.
15126 (next_element_from_buffer): Call compute_stop_pos_backwards to
15127 find a suitable prev_stop when we find ourselves before
15129 (reseat): Don't look for prev_stop, as that could mean a very long
15131 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15132 <cached_disp_overlay_modiff>: Cache for last found display string
15134 (compute_display_string_pos): Return the cached position if asked
15135 about the same buffer in the same area of character positions, and
15136 the buffer wasn't changed since the time the display string
15137 position was cached.
15139 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15141 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15142 is an integer, which is important for empty lines. (Bug#9149)
15144 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15146 * frame.c (Fmodify_frame_parameters): In tty case, update the
15147 default face if necessary (Bug#4238).
15149 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15151 * editfns.c (Fstring_to_char): No need to explain what a character
15152 is in the docstring (Bug#6576).
15154 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15156 * xml.c (parse_region): Make sure we always return a tree.
15158 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15160 * xml.c (parse_region): If a document contains only comments,
15163 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15165 * xml.c (make_dom): Return comments, too.
15167 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15170 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15171 and the surrounding thread.
15172 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15173 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15174 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15176 * s/openbsd.h (BROKEN_SIGIO): Define.
15177 * unexelf.c (unexec) [__OpenBSD__]:
15178 Don't update the .mdebug section of the Alpha COFF symbol table.
15180 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15182 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15185 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15187 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15188 This fixes some race conditions on the permissions of any newly
15191 * alloc.c (valid_pointer_p): Use pipe, not open.
15192 This fixes some permissions issues when debugging.
15194 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15195 If fchown fails to set both uid and gid, try to set just gid,
15196 as that is sometimes allowed. Adjust the file's mode to eliminate
15197 setuid or setgid bits that are inappropriate if fchown fails.
15199 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15201 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15202 to compare Lisp_Objects.

15207 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15209 * lread.c (read_integer): Unread even EOF character.
15210 (read1): Likewise. Properly record start position of symbol.

15213 symbol character follows.
15215 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15217 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15218 This works around a problem with the previous change to Fcopy_file.
15219 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15220 and without this change, GCC might complain about discarding
15221 fchown's return value.
15223 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15225 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15227 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15229 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15231 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15233 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15234 it's used from the C level.
15236 * process.c: Use the same condition for POLL_FOR_INPUT in both
15237 keyboard.c and process.c (bug#1858).

15246 * doc.c (Fsubstitute_command_keys): Revert last change.
15248 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15250 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15251 quotes the next character, and doesn't affect other longer
15252 sequences (bug#8935).
15254 * lread.c (syms_of_lread): Clarify that is isn't only
15255 `eval-buffer' and `eval-defun' that's affected by
15256 `lexical-binding' (bug#8460).

15265 Fix minor problems found by static checking.
15266 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15267 (elsz): Now a signed constant, not a size_t var. We prefer signed
15268 types to unsigned, to avoid integer comparison confusion. Without
15269 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15270 "cannot optimize loop, the loop counter may overflow", a symptom
15272 * indent.c (Fvertical_motion): Mark locals as initialized.
15273 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15275 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

15301 (display_string): If we need to ignore text properties of
15302 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15303 original value of -1 will not work with bidi.)
15304 (compute_display_string_pos): First arg is now struct
15305 `text_pos *'; all callers changed. Support display properties on
15307 (compute_display_string_end): Support display properties on Lisp
15309 (init_iterator, reseat_1, reseat_to_string): Initialize the
15310 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15311 when iterating on a string not from display properties).
15312 (compute_display_string_pos, compute_display_string_end):
15313 Fix calculation of the object to scan. Fixes an error when using
15315 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15316 base_level_stop; instead, set base_level_stop to BEGV.
15317 Fixes crashes in vertical-motion.
15318 (next_element_from_buffer): Improve commentary for when
15319 the iterator is before prev_stop.
15320 (init_iterator): Initialize bidi_p from the default value of
15321 bidi-display-reordering, not from buffer-local value. Use the
15322 buffer-local value only if initializing for buffer iteration.

15343 parts of next_element_from_buffer, next_element_from_string, and
15344 next_element_from_c_string.
15345 (tool_bar_lines_needed, redisplay_tool_bar)
15346 (display_menu_bar): Force left-to-right direction. Add a FIXME
15347 comment for making that be controlled by a user option.

15357 iterator for displaying display or overlay strings.
15358 (forward_to_next_line_start): Don't use the shortcut if
15360 (back_to_previous_visible_line_start): If handle_display_prop
15361 pushed the iterator stack, restore the internal state of the bidi
15362 iterator by calling bidi_pop_it same number of times.
15363 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15364 and we are bidi-iterating, don't decrement the iterator position;
15365 instead, set the first_elt flag in the bidi iterator, to produce
15367 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15368 (push_display_prop): xassert that we are iterating a buffer.

15372 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15373 correctly. Don't assume unibyte strings are not bidi-reordered.

15382 property. Fix a typo in popping stretch info. Add an assertion
15383 for verifying that the iterator position is in sync with the bidi
15385 (handle_single_display_spec, get_overlay_strings_1)

15797 (clone_per_buffer_values): Don't assume that

15799 This isn't true in general, and it's particularly not true
15800 if Emacs is configured with --with-wide-int.
15801 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15802 New macros, used in the buffer.c change.

15838 Random fixes. E.g., (random) never returned negative values.
15839 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15840 subseconds part to the entropy, as that's a bit more random.
15841 Prefer signed to unsigned, since the signedness doesn't matter and
15842 in general we prefer signed. When given a limit, use a
15843 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15844 latter isn't right if USE_2_TAGS_FOR_INTS.
15845 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15846 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15858 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15859 This is more efficient than Ffile_directory_p and avoids a minor race.

15863 * buffer.c (Foverlay_put): Say what the return value is
15866 * fileio.c (barf_or_query_if_file_exists): Check first if the file

15870 error be more correct.
15872 * fns.c (Frequire): Remove the mention of the .gz files, since
15873 that's installation-specific, but keep the mention of
15874 `get-load-suffixes'.

15889 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15890 Also (re)move comments that are misplaced or no longer relevant.

15919 * lread.c (syms_of_lread): Mention single symbols defined by

15991 * eval.c (struct backtrace): Simplify and port the data structure.
15992 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15993 signed bit field, as this assumption is not portable and it makes
15994 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15995 "char debug_on_exit : 1" as this is not portable either; instead,
15996 use the portable "unsigned int debug_on_exit : 1". Remove unused
15997 member evalargs. Remove obsolete comments about cc bombing out.
15999 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16066 (get_parent_class, emacs_fixed_set_min_size): Remove.
16067 (emacs_fixed_new): Set priv->f to argument.
16068 (emacs_fixed_get_preferred_width)
16069 (emacs_fixed_get_preferred_height): Use min_width/height from
16070 frames size_hint to set minimum and natural (Bug#8919).
16071 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
16072 and use min_width/height from frames size_hint to set
16073 min_width/height (Bug#8919).
16075 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
16076 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.
16079 2011-06-26 Eli Zaretskii <eliz@gnu.org>
16081 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
16082 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
16085 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
16087 * process.c (wait_reading_process_output): Bypass select if
16088 waiting for a cell while ignoring keyboard input, and input is
16089 pending. Suggested by Jan Djärv (Bug#8869).
16091 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
16093 Use gnulib's dup2 module instead of rolling our own.
16094 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
16096 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16098 * dispnew.c (scrolling_window): Before scrolling, turn off a
16099 mouse-highlight in the window being scrolled.
16101 2011-06-24 Juanma Barranquero <lekktu@gmail.com>

16161 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16163 Integer and buffer overflow fixes (Bug#8873).
16165 * print.c (printchar, strout): Check for string overflow.
16166 (PRINTPREPARE, printchar, strout):
16167 Don't set size unless allocation succeeds.
16169 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16170 for sizes. Check for string overflow more accurately.
16171 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16173 * macros.c: Integer and buffer overflow fixes.
16174 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16175 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16176 Use ptrdiff_t, not int, for sizes.
16177 Don't increment bufsize until after realloc succeeds.
16178 Check for size-calculation overflow.
16179 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16181 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16183 * lread.c: Integer overflow fixes.
16184 (read_integer): Radix is now EMACS_INT, not int,
16185 to improve quality of diagnostics for out-of-range radices.
16186 Calculate buffer size correctly for out-of-range radices.
16187 (read1): Check for integer overflow in radices, and in
16188 read-circle numbers.
16189 (read_escape): Avoid int overflow.
16190 (Fload, openp, read_buffer_size, read1)
16191 (substitute_object_recurse, read_vector, read_list, map_obarray):
16192 Use ptrdiff_t, not int, for sizes.

16207 2011-06-22 Leo Liu <sdl.web@gmail.com>
16209 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16210 Move to minibuffer.el.
16212 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16214 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16215 The following patches are for when GLYPH_DEBUG && !XASSERT.
16216 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16217 * dispnew.c (flush_stdout):
16218 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16219 Mark as externally visible.
16220 * dispnew.c (check_window_matrix_pointers): Now static.
16221 * dispnew.c (window_to_frame_vpos):
16222 * xfns.c (unwind_create_frame):
16223 * xterm.c (x_check_font): Remove unused local.
16224 * scroll.c (CHECK_BOUNDS):
16225 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16226 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16227 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16228 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16229 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16231 (debug_method_add): Use va_list and vsprintf rather than relying
16232 on undefined behavior with wrong number of arguments.
16233 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16234 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16235 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16236 since we're not interested in debugging glyphs with old libraries.
16237 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16238 GCC 4.6.0's static checking.
16240 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16242 Integer overflow and signedness fixes (Bug#8873).

16251 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16252 (x_create_bitmap_from_xpm_data):
16253 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16254 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16256 * xfaces.c (load_pixmap):

16258 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16259 (.bitmaps_last, struct x_output.icon_bitmap):
16260 Use ptrdiff_t, not int, for bitmap indexes.
16261 (x_allocate_bitmap_record): Check for size overflow.
16262 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16264 Use ptrdiff_t, not int, for overlay counts.
16265 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16266 * editfns.c (overlays_around, get_pos_property):
16267 * textprop.c (get_char_property_and_overlay):
16268 * xdisp.c (next_overlay_change, note_mouse_highlight):
16269 * xfaces.c (face_at_buffer_position):
16270 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16271 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16272 (Fnext_overlay_change, Fprevious_overlay_change)
16273 (mouse_face_overlay_overlaps, Foverlays_in):
16274 Use ptrdiff_t, not int, for sizes.
16275 (overlays_at, overlays_in): Check for size-calculation overflow.
16277 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16279 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16280 (x_session_initialize): Do not assume string length fits in int.
16282 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16283 This is unlikely, but can occur if DPI is outlandish.
16285 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16286 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16288 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16289 * xrdb.c (magic_file_p, search_magic_path):
16290 Omit last arg SUFFIX; it was always 0. All callers changed.
16291 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16293 * xfont.c (xfont_match): Avoid need for strlen.
16295 * xfns.c: Don't assume strlen fits in int.
16296 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16298 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16299 not unsigned long, as we prefer signed integers. All callers changed.
16300 Detect integer overflow in repeat count.
16301 (message_dolog): Don't assume print length fits in 39 bytes.
16302 (display_mode_element): Don't assume strlen fits in int.
16304 * termcap.c: Don't assume sizes fit in int and never overflow.
16305 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16306 (gobble_line): Check for size-calculation overflow.
16308 * minibuf.c (Fread_buffer):
16309 * lread.c (intern, intern_c_string):
16310 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

16314 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16316 * font.c: Don't assume string length fits in int.
16317 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16318 Use ptrdiff_t, not int.
16319 (font_intern_prop): Don't assume string length fits in int.
16320 Don't assume integer property fits in fixnum.
16321 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16323 * filelock.c: Fix some buffer overrun and integer overflow issues.
16324 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16325 Reformulate so as not to need the command string.
16326 Invoke gzip -cd rather than gunzip, as it's more portable.
16327 (lock_info_type, lock_file_1, lock_file):
16328 Don't assume pid_t and time_t fit in unsigned long.
16329 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16330 (current_lock_owner): Prefer signed type for sizes.
16331 Use memcpy, not strncpy, where memcpy is what is really wanted.
16332 Don't assume (via atoi) that time_t and pid_t fit in int.
16333 Check for time_t and/or pid_t out of range, e.g., via a network share.
16334 Don't alloca where an auto var works fine.
16336 * fileio.c: Fix some integer overflow issues.
16337 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16338 Don't assume string length fits in int.
16339 (directory_file_name): Don't assume string length fits in long.
16340 (make_temp_name): Don't assume pid fits in int, or that its print
16341 length is less than 20.
16343 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16345 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16347 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16349 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16350 We prefer signed integers, even for size calculations.
16352 * emacs.c: Don't assume string length fits in 'int'.
16353 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16354 (main): Don't invoke strlen when not needed.
16356 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16357 (XD_DEBUG_MESSAGE): Don't waste a byte.
16359 * callproc.c (getenv_internal_1, getenv_internal)
16360 (Fgetenv_internal):
16361 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16363 * lread.c (invalid_syntax): Omit length argument.
16364 All uses changed. This doesn't fix a bug, but it simplifies the
16365 code away from its former Hollerith-constant appearance, and it's
16366 one less 'int' to worry about when looking at integer-overflow issues.
16367 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16369 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16370 This didn't break anything, but it didn't help either.
16371 It's confusing to put a bogus integer in a place where the actual
16372 value does not matter.
16373 (LIST_END_P): Remove unused macro and its bogus comment.
16374 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16376 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16377 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16379 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16380 We prefer signed types, and the value cannot exceed the EMACS_INT
16381 range anyway (because otherwise the length would not be representable).
16382 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16383 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16384 This avoids a GCC warning when WIDE_EMACS_INT.
16386 * indent.c (sane_tab_width): New function.
16387 (current_column, scan_for_column, Findent_to, position_indentation)
16388 (compute_motion): Use it. This is just for clarity.
16389 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16391 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16393 * lisp.h (lint_assume): New macro.
16394 * composite.c (composition_gstring_put_cache):
16395 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16397 * editfns.c, insdel.c:
16398 Omit unnecessary forward decls, to simplify future changes.
16400 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16402 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16404 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16405 Use much-faster test for byte-length change.
16406 Don't assume string byte-length fits in 'int'.
16407 Check that character arg fits in 'int'.
16408 (mapcar1): Declare byte as byte, for clarity.
16410 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16412 * fns.c (concat): Catch string overflow earlier.
16413 Do not rely on integer wraparound.
16415 * dispextern.h (struct it.overlay_strings_charpos)
16416 (struct it.selective): Now EMACS_INT, not int.
16417 * xdisp.c (forward_to_next_line_start)
16418 (back_to_previous_visible_line_start)
16419 (reseat_at_next_visible_line_start, next_element_from_buffer):
16420 Don't arbitrarily truncate the value of 'selective' to int.
16422 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16424 * composite.c: Don't truncate sizes to 'int'.
16425 (composition_gstring_p, composition_reseat_it)
16426 (composition_adjust_point): Use EMACS_INT, not int.
16427 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16428 not EMACS_UINT, for indexes.
16430 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16432 * buffer.c: Include <verify.h>.
16433 (struct sortvec.priority, struct sortstr.priority):
16434 Now EMACS_INT, not int.
16435 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16436 (struct sortstr.size, record_overlay_string)
16437 (struct sortstrlist.size, struct sortlist.used):
16438 Don't truncate size to int.
16439 (record_overlay_string): Check for size-calculation overflow.
16440 (init_buffer_once): Check at compile-time, not run-time.
16442 2011-06-22 Jim Meyering <meyering@redhat.com>
16444 Don't leak an XBM-image-sized buffer
16445 * image.c (xbm_load): Free the image buffer after using it.
16447 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16450 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16451 that Sun C diagnosed.
16452 * fns.c (secure_hash): Fix pointer signedness issue.
16453 * intervals.c (static_offset_intervals): New function.
16454 (offset_intervals): Use it.
16456 2011-06-21 Leo Liu <sdl.web@gmail.com>
16459 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16462 * fns.c (secure_hash): Rename from crypto_hash_function and change
16463 the first arg to accept symbols.
16464 (Fsecure_hash): New primitive.
16465 (syms_of_fns): New symbols.
16467 2011-06-20 Deniz Dogan <deniz@dogan.se>
16469 * process.c (Fset_process_buffer): Clarify return value in
16472 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16474 * dispnew.c (add_window_display_history): Use BVAR.
16476 * xdisp.c (debug_method_add): Use BVAR.
16477 (check_window_end, dump_glyph_matrix, dump_glyph)
16478 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16480 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16483 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16484 check till after the cache is created in init_frame_faces.
16486 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16488 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16490 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16492 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16493 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16494 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16496 Improve buffer-overflow checking (Bug#8873).
16497 * fileio.c (Finsert_file_contents):
16498 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16499 Remove the old (too-loose) buffer overflow checks.
16500 They weren't needed, since make_gap checks for buffer overflow.
16501 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16502 The old code merely checked for Emacs fixnum overflow, and relied
16503 on undefined (wraparound) behavior. The new code avoids undefined
16504 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16506 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16507 Tune. Don't use wider integers than needed. Don't use alloca.
16508 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16510 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16512 * insdel.c, lisp.h (buffer_overflow): New function.
16513 (insert_from_buffer_1, replace_range, replace_range_2):
16514 * insdel.c (make_gap_larger):
16515 * editfns.c (Finsert_char):
16516 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16518 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16520 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16522 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16524 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16525 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16527 * fileio.c: Don't assume EMACS_INT fits in off_t.
16528 (emacs_lseek): New static function.
16529 (Finsert_file_contents, Fwrite_region): Use it.
16530 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16532 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16534 * fns.c: Don't overflow int when computing a list length.
16535 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16536 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16537 truncation on 64-bit hosts. Check for QUIT every
16538 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16539 faster and is responsive enough.
16540 (Flength): Report an error instead of overflowing an integer.
16541 (Fsafe_length): Return a float if the value is not representable
16542 as a fixnum. This shouldn't happen except in contrived situations.
16543 (Fnthcdr, Fsort): Don't assume list length fits in int.
16544 (Fcopy_sequence): Don't assume vector length fits in int.
16546 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16547 (header_size, word_size): New constants.
16548 (allocate_vectorlike): Don't check size overflow here.
16549 (allocate_vector): Check it here instead, since this is the only
16550 caller of allocate_vectorlike that could cause overflow.
16551 Check that the new vector's length is representable as a fixnum.
16553 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16554 The previous code was bogus. For example, next_almost_prime (32)
16555 returned 39, which is undesirable as it is a multiple of 3; and
16556 next_almost_prime (24) returned 25, which is a multiple of 5 so
16557 why was the code bothering to check for multiples of 7?
16559 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16561 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16563 Variadic C functions now count arguments with ptrdiff_t.
16564 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16565 Back then I didn't know that the Emacs coding style prefers signed int.
16566 Also, in the meantime I found a few more instances where arguments
16567 were being counted with int, which may truncate counts on 64-bit
16568 machines, or EMACS_INT, which may be unnecessarily wide.
16569 * lisp.h (struct Lisp_Subr.function.aMANY)
16570 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16571 Arg counts are now ptrdiff_t, not size_t.
16572 All variadic functions and their callers changed accordingly.
16573 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16574 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16575 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16576 * callint.c (Fcall_interactively): Check arg count for overflow,
16577 to avoid potential buffer overrun. Use signed char, not 'int',
16578 for 'varies' array, so that we needn't bother to check its size
16579 calculation for overflow.
16580 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16581 * eval.c (apply_lambda):
16582 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16583 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16584 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16586 * callint.c (Fcall_interactively): Don't use index var as event count.
16588 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16589 * mem-limits.h (SIZE): Remove; no longer used.
16591 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16593 Remove unnecessary casts.
16594 * xterm.c (x_term_init):
16595 * xfns.c (x_set_border_pixel):
16596 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16597 These aren't needed now that we assume ANSI C.
16599 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16600 It's more likely to cause problems (due to unsigned overflow)
16603 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16605 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16607 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16609 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16611 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16613 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16615 GLYPH_CODE_FACE returns EMACS_INT, not int.
16616 * dispextern.h (merge_faces):
16617 * xfaces.c (merge_faces):
16618 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16619 Don't assume EMACS_INT fits in int.
16621 * character.h (CHAR_VALID_P): Remove unused parameter.
16622 * fontset.c, lisp.h, xdisp.c: All uses changed.
16624 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16626 * fns.c (concat): Minor tuning based on overflow analysis.
16627 This doesn't fix any bugs. Use int to hold character, instead
16628 of constantly refetching from Emacs object. Use XFASTINT, not
16629 XINT, for value known to be a character. Don't bother comparing
16630 a single byte to 0400, as it's always less.
16632 * floatfns.c (Fexpt):
16633 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16635 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16638 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16640 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16641 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16642 incorrectly succeed when S was a string, because 4294967386 was
16643 truncated before it was used.
16645 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16646 Otherwise, an out-of-range integer could cause undefined behavior
16649 * composite.c: Use int, not EMACS_INT, for characters.
16650 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16651 EMACS_INT, for values that are known to be in character range.
16652 This doesn't fix any bugs but is the usual style inside Emacs and
16653 may generate better code on 32-bit machines.
16655 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16656 This is for reasons similar to the recent CHAR_STRING fix.
16657 * charset.c (Fencode_char): Check that character arg is actually
16658 a character. Pass an int to ENCODE_CHAR.
16659 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16660 wider than 'int', as a compile-time check to prevent future regressions
16663 * character.c (char_string): Remove unnecessary casts.
16665 Make sure a 64-bit char is never passed to CHAR_STRING.
16666 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16667 by silently ignoring the top 32 bits, allowing some values
16668 that were far too large to be valid characters.
16669 * character.h: Include <verify.h>.
16670 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16671 arguments are no wider than unsigned, as a compile-time check
16672 to prevent future regressions in this area.
16674 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16675 (Fsubst_char_in_region):
16677 * xdisp.c (decode_mode_spec_coding):
16678 Adjust to CHAR_STRING's new requirement.
16679 * editfns.c (Finsert_char, Fsubst_char_in_region):
16680 * fns.c (concat): Check that character args are actually
16681 characters. Without this test, these functions did the wrong
16682 thing with wildly out-of-range values on 64-bit hosts.
16684 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16685 These casts should not be needed on 32-bit hosts, either.
16686 * keyboard.c (read_char):
16687 * lread.c (Fload): Remove casts to unsigned.
16689 * lisp.h (UNSIGNED_CMP): New macro.
16690 This fixes comparison bugs on 64-bit hosts.
16691 (ASCII_CHAR_P): Use it.
16692 * casefiddle.c (casify_object):
16693 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16694 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16695 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16696 * dispextern.h (FACE_FROM_ID):
16697 * keyboard.c (read_char): Use UNSIGNED_CMP.
16699 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16700 not to EMACS_INT, to avoid GCC warning.
16702 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16704 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16705 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16706 isn't needed on 32-bit machines.
16708 * buffer.c (Fgenerate_new_buffer_name):
16709 Use EMACS_INT for count, not int.
16710 (advance_to_char_boundary): Return EMACS_INT, not int.
16712 * data.c (Qcompiled_function): Now static.
16714 * window.c (window_body_lines): Now static.
16716 * image.c (gif_load): Rename local to avoid shadowing.
16718 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16719 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16720 * alloc.c (make_save_value): Integer argument is now of type
16721 ptrdiff_t, not int.
16722 (mark_object): Use ptrdiff_t, not int.
16723 * lisp.h (pD): New macro.
16724 * print.c (print_object): Use it.
16726 * alloc.c: Use EMACS_INT, not int, to count objects.
16727 (total_conses, total_markers, total_symbols, total_vector_size)
16728 (total_free_conses, total_free_markers, total_free_symbols)
16729 (total_free_floats, total_floats, total_free_intervals)
16730 (total_intervals, total_strings, total_free_strings):
16731 Now EMACS_INT, not int. All uses changed.
16732 (Fgarbage_collect): Compute overall total using a double, so that
16733 integer overflow is less likely to be a problem. Check for overflow
16734 when converting back to an integer.
16735 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16736 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16737 These were 'int' variables that could overflow on 64-bit hosts;
16738 they were never used, so remove them instead of repairing them.
16739 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16740 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16741 Previously, this ceilinged at INT_MAX, but that doesn't work on
16743 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16745 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16746 (allocate_vectorlike): Check for ptrdiff_t overflow.
16747 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16748 when a (possibly-narrower) signed value would do just as well.
16749 We prefer using signed arithmetic, to avoid comparison confusion.
16751 * alloc.c: Catch some string size overflows that we were missing.
16752 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16753 for convenience in STRING_BYTES_MAX.
16754 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16755 The definition here is exact; the one in lisp.h was approximate.
16756 (allocate_string_data): Check for string overflow. This catches
16757 some instances we weren't catching before. Also, it catches
16758 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16759 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16760 and ptrdiff_t and EMACS_INT are both 64 bits.
16762 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16763 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16764 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16766 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16768 * alloc.c (Fmake_string): Check for out-of-range init.
16770 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16772 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16774 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16776 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16777 xg_get_default_scrollbar_width.
16779 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16780 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16781 (style_changed_cb): Call update_theme_scrollbar_width and call
16782 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16783 all frames (Bug#8505).
16784 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16785 Call gtk_window_set_resizable if HAVE_GTK3.
16786 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16787 and height if HAVE_GTK3 (Bug#8505).
16788 (scroll_bar_width_for_theme): New variable.
16789 (update_theme_scrollbar_width): New function.
16790 (xg_get_default_scrollbar_width): Move code to
16791 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16792 (xg_initialize): Call update_theme_scrollbar_width.
16794 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16796 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16798 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16800 * frame.c (make_frame): Call other_buffer_safely instead of
16803 * window.c (temp_output_buffer_show): Call display_buffer with
16804 second argument Vtemp_buffer_show_specifiers and reset latter
16805 immediately after the call.
16806 (Vtemp_buffer_show_specifiers): New variable.
16807 (auto_window_vscroll_p, next_screen_context_lines)
16808 (Vscroll_preserve_screen_position): Remove leading asterisks from
16811 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
16813 Fix minor problems found by GCC 4.6.0 static checking.
16814 * buffer.c (Qclone_number): Remove for now, as it's unused.
16815 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
16816 (record_buffer): Remove unused local.
16817 * frame.c (other_visible_frames, frame_buffer_list): Now static.
16818 (set_frame_buffer_list): Remove; unused.
16819 * frame.h (other_visible_frames): Remove decl.
16820 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
16821 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
16822 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
16824 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
16825 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
16826 Define only if HAVE_GPM.
16827 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
16828 (update_hints_inhibit): Remove; never set. All uses removed.
16829 * widgetprv.h (emacsFrameClassRec): Remove decl.
16830 * window.c (delete_deletable_window): Now returns void, since it
16831 wasn't returning anything.
16832 (compare_window_configurations): Remove unused locals.
16833 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
16834 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
16835 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
16836 the same widths as pointers. This follows up on the 2011-05-06 patch.
16837 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
16838 * xterm.h: Likewise.
16839 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

16844 (LISP_H): Add lib/intprops.h.
16846 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
16848 * image.c (gif_load): Add animation frame delay to the metadata.
16849 (syms_of_image): Use DEFSYM. New symbol `delay'.
16851 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16853 * window.c (delete_deletable_window): Re-add.
16854 (Fset_window_configuration): Rewrite to handle dead buffers and
16855 consequently deletable windows.
16856 (window_tree, Fwindow_tree): Remove. Supply functionality in
16858 (compare_window_configurations): Simplify code.
16860 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
16862 * image.c (imagemagick_load_image): Fix type mismatch.
16863 (Fimagemagick_types): Likewise.
16865 * window.h (replace_buffer_in_windows): Declare.
16867 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16869 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
16870 Qclone_number. Remove external declaration of Qdelete_window.
16871 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
16873 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
16874 Run Qbuffer_list_update_hook if allowed.
16875 (Fother_buffer): Rewrite doc-string. Major rewrite for new
16876 buffer list implementation.
16877 (other_buffer_safely): New function.
16878 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
16879 calls to replace_buffer_in_windows and
16880 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
16882 (record_buffer): Inhibit quitting and rewrite using quittable
16883 functions. Run Qbuffer_list_update_hook if allowed.
16884 (Frecord_buffer, Funrecord_buffer): New functions.
16885 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
16886 Move switch-to-buffer to window.el.
16887 (bury-buffer): Move to window.el.
16888 (Vbuffer_list_update_hook): New variable.
16890 * lisp.h (other_buffer_safely): Add prototype in buffer.c
16893 * window.h (resize_frame_windows): Move up in code.
16894 (Fwindow_frame): Remove EXFUN.
16895 (replace_buffer_in_all_windows): Remove prototype.
16896 (replace_buffer_in_windows_safely): Add prototype.
16898 * window.c: Declare Qdelete_window static again. Move down
16899 declaration of select_count.
16900 (Fnext_window, Fprevious_window): Rewrite doc-strings.
16901 (Fother_window): Move to window.el.
16902 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
16903 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
16904 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
16906 (replace_buffer_in_windows): Implement by calling
16907 Qreplace_buffer_in_windows.
16908 (replace_buffer_in_all_windows): Remove with some functionality
16909 moved into replace_buffer_in_windows_safely.
16910 (replace_buffer_in_windows_safely): New function.
16911 (select_window_norecord, select_frame_norecord): Move in front
16912 of run_window_configuration_change_hook. Remove now obsolete
16914 (Fset_window_buffer): Rewrite doc-string.
16915 Call Qrecord_window_buffer.
16916 (keys_of_window): Move binding for other-window to window.el.
16918 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
16920 * dispextern.h (struct image): Replace data member, whose int_val
16921 and ptr_val fields were not used by anything, with a single
16924 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
16925 (gif_clear_image, gif_load, imagemagick_load_image)
16926 (gs_clear_image, gs_load): Callers changed.
16928 2011-06-10 Paul Eggert <eggert@cs.ucla.edu>

17379 (compute_display_string_pos, compute_display_string_end):
17381 (push_it): Accept second argument POSITION, where pop_it should
17382 jump to continue iteration.
17383 (reseat_1): Initialize bidi_it.disp_pos.
17385 * keyboard.c (adjust_point_for_property): Adjust the call to
17386 display_prop_intangible_p to its new signature.

17396 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
17398 Malloc failure behavior now depends on size of allocation.
17399 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
17400 * lisp.h: Change signatures accordingly.
17401 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
17402 All callers changed. (Bug#8762)
17404 * gnutls.c: Use Emacs's memory allocators.
17405 Without this change, the gnutls library would invoke malloc etc.
17406 directly, which causes problems on non-SYNC_INPUT hosts, and which
17407 runs afoul of improving memory_full behavior. (Bug#8761)
17408 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17409 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17410 xfree instead of the default malloc, realloc, free.
17411 (Fgnutls_boot): No need to check for memory allocation failure,
17412 since xmalloc does that for us.
17414 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17415 * category.c (hash_get_category_set):
17416 * ccl.c (ccl_driver):
17417 * charset.c (Fdefine_charset_internal):
17418 * charset.h (struct charset.hash_index):
17419 * composite.c (get_composition_id, gstring_lookup_cache)
17420 (composition_gstring_put_cache):
17421 * composite.h (struct composition.hash_index):

17428 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
17429 (Fsxhash, Fgethash, Fputhash, Fmaphash):
17430 * image.c (make_image, search_image_cache, lookup_image)
17431 (xpm_put_color_table_h):
17432 * lisp.h (struct Lisp_Hash_Table):
17433 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
17434 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17435 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17436 * alloc.c (allocate_vectorlike):
17437 Check for overflow in vector size calculations.
17438 * ccl.c (ccl_driver):
17439 Check for overflow when converting EMACS_INT to int.
17440 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17441 need to be updated by these changes.
17442 * fns.c (make_hash_table, maybe_resize_hash_table):
17443 Check for integer overflow with large hash tables.
17444 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17445 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17446 (SXHASH_REDUCE): New macro.
17447 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17448 Use it instead of discarding useful hash info with large hash values.
17449 (sxhash_float): New function.
17450 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17451 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17452 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17453 Rewrite to use FIXNUM_BITS, as this simplifies things.
17454 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17455 Adjust signatures to match updated version of code.
17456 (consing_since_gc): Now EMACS_INT, since a single hash table can
17457 use more than INT_MAX bytes.
17459 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17461 Make it possible to build with GCC-4.6+ -O2 -flto.
17463 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17465 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17467 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17468 Call minibuffer-inactive-mode.
17470 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17472 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17473 Update dependencies.
17475 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17477 * data.c (init_data): Remove code for UTS, this system is not
17480 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17482 Don't force ./temacs to start in terminal mode.
17484 * frame.c (make_initial_frame): Initialize faces in all cases, not
17485 only when CANNOT_DUMP is defined.
17486 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17488 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17490 * dispnew.c (add_window_display_history): Use const for the string
17491 pointer. Remove declaration, not needed.
17493 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17495 Use 'inline', not 'INLINE'.
17496 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17497 * alloc.c, fontset.c (INLINE): Remove.
17498 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17499 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17500 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17501 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17502 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17504 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17506 Make it possible to run ./temacs.
17508 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17509 syms_of_callproc does the same thing. Remove test for
17510 "initialized", do it in the caller.
17511 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17513 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17515 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17516 (read_minibuf): Use get_minibuffer.
17517 (syms_of_minibuf): Use DEFSYM.
17518 (Qmetadata): New var.
17519 * data.c (Qbuffer): Don't make it static.
17520 (syms_of_data): Use DEFSYM.
17522 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17524 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17525 (CCL_CODE_MIN): New macro.
17527 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17529 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17531 * eval.c (Qdebug): Now static.
17532 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17533 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17534 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17536 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17538 * image.c: Various fixes to ImageMagick code comments.
17539 (Fimagemagick_types): Doc fix.
17541 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17543 Minor fixes prompted by GCC 4.6.0 warnings.
17545 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17547 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17548 (x_clipboard_manager_save_all): Move extern decl to ...
17549 * xterm.h: ... here, so that it can be checked for consistency.
17551 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17553 * xselect.c (x_clipboard_manager_save_frame)
17554 (x_clipboard_manager_save_all): New functions.
17555 (Fx_clipboard_manager_save): Lisp function deleted.
17557 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17558 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17560 * xterm.h: Update prototype.
17562 2011-05-28 William Xu <william.xwl@gmail.com>
17564 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17565 exiting (Bug#8239).
17567 2011-05-28 Jim Meyering <meyering@redhat.com>
17569 Avoid a sign-extension bug in crypto_hash_function.
17570 * fns.c (to_uchar): Define.
17571 (crypto_hash_function): Use it to convert some newly-signed
17572 variables to unsigned, to avoid sign-extension bugs. For example,
17573 without this change, (md5 "truc") would evaluate to
17574 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17575 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17576 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17578 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17580 Integer overflow fixes.
17582 * dbusbind.c: Serial number integer overflow fixes.
17583 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17584 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17585 to hold a serial number that is too large for a fixnum.
17586 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17587 Check for serial numbers out of range. Decode any serial number
17588 that was so large that it became a float. (Bug#8722)
17590 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17591 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17592 Use XFASTINT rather than XUINT when numbers are nonnegative.
17593 (xd_append_arg, Fdbus_method_return_internal):
17594 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17595 arguments, check that Lisp number is nonnegative, rather than
17596 silently wrapping negative numbers around. (Bug#8722)
17597 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17600 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17602 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17604 ccl: Add integer overflow checks.
17605 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17606 (IN_INT_RANGE): New macros.
17607 (ccl_driver): Use them to check for integer overflow when
17608 decoding a CCL program. Many of the new checks are whether XINT (x)
17609 fits in int; it doesn't always, on 64-bit hosts. The new version
17610 doesn't catch all possible integer overflows, but it's an
17611 improvement. (Bug#8719)
17613 * alloc.c (make_event_array): Use XINT, not XUINT.
17614 There's no need for unsigned here.
17616 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17617 This follows up to the 2011-05-06 change that substituted uintptr_t
17618 for EMACS_INT. This case wasn't caught back then.
17620 Rework Fformat to avoid integer overflow issues.
17621 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17622 now (part of C89). Include <verify.h>.
17623 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17624 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17625 (Fformat): Avoid the prepass trying to compute sizes; it was only
17626 approximate and thus did not catch overflow reliably. Instead, walk
17627 through the format just once, formatting and computing sizes as we go,
17628 checking for integer overflow at every step, and allocating a larger
17629 buffer as needed. Keep track separately whether the format is
17630 multibyte. Keep only the most-recently calculated precision, rather
17631 than them all. Record whether each argument has been converted to
17632 string. Use EMACS_INT, not int, for byte and char and arg counts.
17633 Support field widths and precisions larger than INT_MAX. Avoid
17634 sprintf's undefined behavior with conversion specifications such as %#d
17635 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17636 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17637 formatting out-of-range floating point numbers with int
17638 formats. (Bug#8668)
17640 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17642 * data.c: Avoid integer truncation in expressions involving floats.
17643 * data.c: Include <intprops.h>.
17644 (arith_driver): When there's an integer overflow in an expression
17645 involving floating point, convert the integers to floating point
17646 so that the resulting value does not suffer from catastrophic
17647 integer truncation. For example, on a 64-bit host (* 4
17648 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17649 Do not rely on undefined behavior after integer overflow.
17651 merge count_size_as_multibyte, parse_str_to_multibyte
17652 * character.c, character.h (count_size_as_multibyte):
17653 Rename from parse_str_to_multibyte; all uses changed.
17654 Check for integer overflow.
17655 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17656 since it's now a duplicate of the other. This is more of
17657 a character than a buffer op, so better that it's in character.c.
17658 * fns.c, print.c: Adjust to above changes.
17660 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17662 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17664 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17666 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17667 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17668 (x_clipboard_manager_save): Now static.
17669 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17671 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17672 (crypto_hash_function): Now static.
17673 Fix pointer signedness problems. Avoid unnecessary initializations.
17675 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17677 * termhooks.h (Vselection_alist): Make it terminal-local.
17679 * terminal.c (create_terminal): Initialize it.
17681 * xselect.c: Support for clipboard managers.
17682 (Vselection_alist): Move to termhooks.h as terminal-local var.
17683 (LOCAL_SELECTION): New macro.
17684 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17685 (symbol_to_x_atom): Remove gratuitous arg.
17686 (x_handle_selection_request, lisp_data_to_selection_data)
17687 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17688 (x_own_selection, x_get_local_selection, x_convert_selection):
17689 New arg, specifying work frame. Use terminal-local Vselection_alist.
17690 (some_frame_on_display): Delete unused function.
17691 (Fx_own_selection_internal, Fx_get_selection_internal)
17692 (Fx_disown_selection_internal, Fx_selection_owner_p)
17693 (Fx_selection_exists_p): New optional frame arg.
17694 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17695 (x_handle_selection_clear): Don't treat other terminals with the
17696 same keyboard specially. Use the terminal-local Vselection_alist.
17697 (x_clear_frame_selections): Use Frun_hook_with_args.
17699 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17701 * xterm.h: Add support for those atoms.
17703 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17705 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17706 (converted_selections, conversion_fail_tag): New global variables.
17707 (x_selection_request_lisp_error): Free the above.
17708 (x_get_local_selection): Remove unnecessary code.
17709 (x_reply_selection_request): Args changed; handle arbitrary array
17710 of converted selections stored in converted_selections.
17711 Separate the XChangeProperty and SelectionNotify steps.
17712 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17713 (x_convert_selection): New function.
17714 (x_handle_selection_event): Simplify.
17715 (x_get_foreign_selection): Don't ignore incoming requests while
17716 waiting for an answer; this will fail when we implement
17717 SAVE_TARGETS, and seems unnecessary anyway.
17718 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17719 (Vx_sent_selection_functions): Doc fix.
17721 2011-05-26 Leo Liu <sdl.web@gmail.com>
17723 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17725 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17727 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17729 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17730 for fringe update if it has periodic bitmap.
17731 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17732 and fringe_bitmap_periodic_p.
17734 * fringe.c (get_fringe_bitmap_data): New function.
17735 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17736 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17737 row. Mark glyph row for fringe update if periodicity changed.
17739 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17740 for fringe update unless it has periodic bitmap.
17742 2011-05-25 Kenichi Handa <handa@m17n.org>

17760 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17761 Remove macros that are defined and never used.
17762 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17764 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17766 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17767 (Fx_get_selection_internal): Minor cleanup.

17795 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17797 * systime.h (Time): Define only if emacs is defined.
17798 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17799 where the include path doesn't have X11/X.h by default. See
17800 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17802 2011-05-20 Kenichi Handa <handa@m17n.org>
17804 * composite.c (find_automatic_composition): Fix previous change.
17806 2011-05-20 Glenn Morris <rgm@gnu.org>

17815 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17816 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17817 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17818 (lisp): Set the order to that of loadup.el.
17819 (shortlisp): Make it a copy of $lisp.
17820 (SOME_MACHINE_LISP): Remove.
17821 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17822 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17824 2011-05-18 Kenichi Handa <handa@m17n.org>
17826 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17827 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17828 (find_automatic_composition): Mostly rewrite for efficiency.
17830 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17832 * makefile.w32-in: Update dependencies.
17834 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17836 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17837 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17839 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17841 Fix some integer overflow issues, such as string length overflow.
17843 * insdel.c (count_size_as_multibyte): Check for string overflow.
17845 * character.c (lisp_string_width): Check for string overflow.
17846 Use EMACS_INT, not int, for string indexes and lengths; in
17847 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17848 the resulting string length overflows an EMACS_INT; instead,
17849 report a string overflow if no precision given. When checking for
17850 precision exhaustion, use a check that cannot possibly have
17851 integer overflow. (Bug#8675)
17852 * character.h (lisp_string_width): Adjust to new signature.
17854 * alloc.c (string_overflow): New function.
17855 (Fmake_string): Use it. This doesn't change behavior, but saves
17856 a few bytes and will simplify future changes.
17857 * character.c (string_escape_byte8): Likewise.
17858 * lisp.h (string_overflow): New decl.
17860 Fixups, following up to the user-interface timestamp change.
17861 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17862 for UI timestamps, instead of unsigned long.
17863 * msdos.c (mouse_get_pos): Likewise.
17864 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17865 * w32gui.h (Time): Define by including "systime.h" rather than by
17866 declaring it ourselves. (Bug#8664)
17868 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17869 * image.c (clear_image_cache): Likewise.
17871 * term.c (term_mouse_position): Don't assume time_t wraparound.
17873 Be more systematic about user-interface timestamps.
17874 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17875 and sometimes 'EMACS_UINT', to represent these timestamps.
17876 This change causes it to use 'Time' uniformly, as that's what X uses.
17877 This makes the code easier to follow, and makes it easier to catch
17878 integer overflow bugs such as Bug#8664.
17879 * frame.c (Fmouse_position, Fmouse_pixel_position):
17880 Use Time, not unsigned long, for user-interface timestamps.
17881 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17882 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17883 * keyboard.h (last_event_timestamp): Likewise.
17884 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17885 * menu.h (xmenu_show): Likewise.
17886 * term.c (term_mouse_position): Likewise.
17887 * termhooks.h (struct input_event.timestamp): Likewise.
17888 (struct terminal.mouse_position_hook): Likewise.
17889 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17890 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17891 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17892 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17893 what it was before.
17894 * menu.h, termhooks.h: Include "systime.h", for Time.
17896 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17897 Don't assume that the difference between two unsigned long values
17898 can fit into an integer. At this point, we know button_down_time
17899 <= event->timestamp, so the difference must be nonnegative, so
17900 there's no need to cast the result if double-click-time is
17901 nonnegative, as it should be; check that it's nonnegative, just in
17902 case. This bug is triggered when events are more than 2**31 ms
17903 apart (about 25 days). (Bug#8664)
17905 * xselect.c (last_event_timestamp): Remove duplicate decl.
17906 (x_own_selection): Remove needless cast to unsigned long.
17908 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17909 that always fit in int. Use a sentinel instead of a counter, to
17910 avoid a temp and to allay GCC's concerns about possible int overflow.
17911 * frame.h (struct frame): Use int for menu_bar_items_used
17912 instead of EMACS_INT, since it always fits in int.
17914 * menu.c (grow_menu_items): Check for int overflow.
17916 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17918 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17919 Before, the code was not consistent. These values cannot exceed
17920 2**31 - 1 so there's no need to make them unsigned.
17921 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17922 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17923 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17925 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17927 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17928 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17929 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17930 presumably because the widths might not match.
17932 * window.c (size_window): Avoid needless test at loop start.
17934 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17936 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17938 2011-05-12 Drew Adams <drew.adams@oracle.com>
17940 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17942 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17944 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17945 `width' to `bar_area_x' and `bar_area_width', respectively.
17946 (x_scroll_run): Take account of fringe background extension.
17948 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17949 Rename local vars `left' and `width' to `bar_area_x' and
17950 `bar_area_width', respectively.
17951 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17952 background extension.
17954 2011-05-10 Jim Meyering <meyering@redhat.com>
17956 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17958 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17960 * image.c (Finit_image_library): Return t for built-in image types,
17961 like pbm and xbm. (Bug#8640)
17963 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17965 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17967 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17969 * w32console.c (Fset_screen_color): Doc fix.
17970 (Fget_screen_color): New function.
17971 (syms_of_ntterm): Defsubr it.
17973 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17974 unlink the temporary file if Fcall_process didn't create it in the
17976 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17977 child process will be redirected to a file specified with `:file'.
17978 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17979 cue to call_process_cleanup not to close that handle.
17981 2011-05-07 Ben Key <bkey76@gmail.com>
17983 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17984 one of two shell specific rules, either bootstrap-temacs-CMD or
17985 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17986 to the previous implementation of the bootstrap-temacs rule.
17987 The bootstrap-temacs-CMD rule is similar to the previous
17988 implementation of the bootstrap-temacs rule except that it
17989 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17992 These changes, along with some changes to nt/configure.bat,
17993 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17994 earlier fix to add support for --cflags and --ldflags options
17995 that include quotes so that it works whether make uses cmd or
17998 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18000 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18001 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18003 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18004 a string. Handle both cases.
18005 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18006 (Fdbus_register_method): Use Qinvalid_function.
18008 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18010 * makefile.w32-in: Update dependencies.
18011 (LISP_H): Add inttypes.h and stdin.h.
18012 (PROCESS_H): Add unistd.h.
18014 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18016 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18017 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18019 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18021 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18023 * term.c (vfatal): Remove stray call to va_end.
18024 It's not needed and the C Standard doesn't allow it here anyway.
18026 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18027 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18029 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18032 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18034 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18036 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18038 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18040 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18042 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18043 * charset.c (Fdefine_charset_internal): Don't initialize
18044 charset.code_space[15]. The value was garbage, on hosts with
18045 32-bit int (Bug#8600).
18047 * lread.c (read_integer): Be more consistent with string-to-number.
18048 Use string_to_number to do the actual conversion; this avoids
18049 rounding errors and fixes some other screwups. Without this fix,
18050 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18051 (digit_to_number): Move earlier, for benefit of read_integer.
18052 Return -1 if the digit is out of range for the base, -2 if it is
18053 not a digit in any supported base. (Bug#8602)
18055 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18057 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18058 to match comment at start of function. This also removes a
18059 GCC warning about overflow in a 32+64-bit port.
18061 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18063 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18064 Reported by Stefan Monnier in
18065 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18066 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18067 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18069 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18070 (EMACS_UINTPTR): Likewise, with uintptr_t.
18072 * lisp.h: Prefer 64-bit EMACS_INT if available.
18073 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18074 on 32-bit hosts that have 64-bit int, so that they can access
18076 However, temporarily disable this change unless the temporary
18077 symbol WIDE_EMACS_INT is defined.
18079 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18081 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18082 This removes an assumption that EMACS_INT and long are the same
18083 width as pointers. The assumption is true for Emacs porting targets
18084 now, but we want to make other targets possible.
18085 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18086 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18087 In the rest of the code, change types of integers that hold casted
18088 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18089 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18090 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18091 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18092 No need to cast type when ORing.
18093 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18094 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18095 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18096 assume EMACS_INT is the same width as char *.
18097 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18098 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18099 Remove no-longer-needed casts.
18100 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18101 (xg_tool_bar_help_callback, xg_make_tool_item):
18102 Use EMACS_INTPTR to hold an integer
18103 that will be cast to void *; this can avoid a GCC warning
18104 if EMACS_INT is not the same width as void *.
18105 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18106 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18107 (current_message_1, set_message_1):
18108 Use a local to convert to proper width without a cast.
18109 * xmenu.c (dialog_selection_callback): Likewise.
18111 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18112 Also, don't assume VALBITS / RAND_BITS is less than 5,
18113 and don't rely on undefined behavior when shifting a 1 left into
18115 * lisp.h (get_random): Change signature to match.
18117 * lread.c (hash_string): Use size_t, not int, for hash computation.
18118 Normally we prefer signed values; but hashing is special, because
18119 it's better to use unsigned division on hash table sizes so that
18120 the remainder is nonnegative. Also, size_t is the natural width
18121 for hashing into memory. The previous code used 'int', which doesn't
18122 retain enough info to hash well into very large tables.
18123 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18125 * dbusbind.c: Don't possibly lose pointer info when converting.
18126 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18127 Use XPNTR rather than XHASH, so that the high-order bits of
18128 the pointer aren't lost when converting through void *.
18130 * eval.c (Fautoload): Don't double-shift a pointer.
18132 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18134 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18136 * gnutls.c (DEF_GNUTLS_FN):
18137 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18139 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18141 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18144 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18146 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18147 New version that can reserve upto 2GB of heap space.
18149 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18151 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18153 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18155 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18156 `gnutls_certificate_set_x509_key_file'.
18158 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18160 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18161 Update dependencies.
18163 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18165 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18166 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18167 Remove unused parameter `fildes'.
18168 * process.c (read_process_output, send_process): Don't pass it.
18170 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18172 Fix previous change: the library cache is defined in w32.c.
18173 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18174 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18176 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18178 Implement dynamic loading of GnuTLS on Windows.
18180 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18181 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18182 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18185 * gnutls.c (Qgnutls_dll): Define.
18186 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18187 (gnutls_*): Declare function pointers.
18188 (init_gnutls_functions): New function to initialize function pointers.
18189 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18190 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18191 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18192 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18193 (emacs_gnutls_write, emacs_gnutls_read)
18194 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18195 (Fgnutls_available_p): New function.
18196 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18197 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18198 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18200 * image.c: Include w32.h.
18201 (Vimage_type_cache): Delete.
18202 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18203 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18204 (w32_delayed_load): Move to w32.c.
18206 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18208 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18209 (w32_delayed_load): Move from image.c. When loading a library, record
18210 its filename in the :loaded-from property of the library id.
18211 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18212 Initialize and staticpro them.
18213 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18215 * process.c: Include lisp.h before w32.h, not after.
18216 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18217 instead of gnutls_record_check_pending.
18219 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18221 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18223 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18224 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18227 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18229 * xterm.c (x_set_frame_alpha): Do not set property on anything
18230 else than FRAME_X_OUTER_WINDOW (Bug#8608).

18266 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18268 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18269 rather than `XVECTOR (FOO)->size'.
18271 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18272 inttypes.h, as a gnulib replacement is used if it not available in
18275 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18277 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18278 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18279 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18281 * coding.c (coding_alloc_by_realloc): Error out if destination
18282 will grow beyond MOST_POSITIVE_FIXNUM.
18283 (decode_coding_emacs_mule): Abort if there isn't enough place in
18284 charbuf for the composition carryover bytes. Reserve an extra
18285 space for up to 2 characters produced in a loop.
18286 (decode_coding_iso_2022): Abort if there isn't enough place in
18287 charbuf for the composition carryover bytes.
18289 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18291 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18292 aborting when %lld or %lll format is passed.
18293 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18294 %llo or %llx format is passed. (Bug#8545)
18296 * window.c (window_scroll_line_based): Use a marker instead of
18297 simple variables to record original value of point. (Bug#7952)
18299 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18300 produced by %s or %c overflows available buffer space. (Bug#8545)
18302 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18304 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18305 (SIZE_MAX): Move defn after all includes, as they might #define it.
18307 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18309 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18311 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18313 * keyboard.c (Qdelayed_warnings_hook): Define.
18314 (command_loop_1): Run `delayed-warnings-hook'
18315 if Vdelayed_warnings_list is non-nil.
18316 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18317 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18319 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18321 * doprnt.c (doprnt): Don't return value smaller than the buffer
18322 size if the message was truncated. (Bug#8545).
18324 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18326 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18327 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18329 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18331 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18333 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18335 * makefile.w32-in: Update dependencies.
18337 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18339 Improve `doprnt' and its usage. (Bug#8545)
18340 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18341 `format_end'. Remove support for %l as a conversion specifier.
18342 Don't use xrealloc. Improve diagnostics when the %l size modifier
18343 is used. Update the commentary.
18345 * eval.c (verror): Simplify calculation of size_t.
18347 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18350 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18352 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18355 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18357 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18358 This makes this file independent of the recent pseudovector change.
18360 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18362 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18364 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18365 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18366 Remove unused local.
18367 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18369 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18370 GCC 4.6.0 optimizes based on type-based alias analysis.
18371 For example, if b is of type struct buffer * and v of type struct
18372 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18373 != &v->size, and therefore "v->size = 1; b->size = 2; return
18374 v->size;" must therefore return 1. This assumption is incorrect
18375 for Emacs, since it type-puns struct Lisp_Vector * with many other
18376 types. To fix this problem, this patch adds a new type struct
18377 vectorlike_header that documents the constraints on layout of vectors
18378 and pseudovectors, and helps optimizing compilers not get fooled
18379 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18380 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18381 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18383 (XSETPVECTYPE): Rewrite in terms of new macro.
18384 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18385 This is a bit clearer, and further avoids the possibility of
18386 undesirable aliasing.
18387 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18388 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18389 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18390 since Lisp_Subr is a special case (no "next" field).
18391 (ASIZE): Now uses header.size rather than size.
18392 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18393 to avoid the hassle of writing XVECTOR (foo)->header.size.
18394 (struct vectorlike_header): New type.
18395 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18396 object, to help avoid aliasing.
18397 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18398 (SUBRP): Likewise, since Lisp_Subr is a special case.
18399 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18400 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18401 (struct Lisp_Hash_Table): Combine first two members into a single
18402 struct vectorlike_header member. All uses of "size" and "next" members
18403 changed to be "header.size" and "header.next".
18404 * buffer.h (struct buffer): Likewise.
18405 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18406 * frame.h (struct frame): Likewise.
18407 * process.h (struct Lisp_Process): Likewise.
18408 * termhooks.h (struct terminal): Likewise.
18409 * window.c (struct save_window_data, struct saved_window): Likewise.
18410 * window.h (struct window): Likewise.
18411 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18412 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18413 * buffer.c (init_buffer_once): Likewise.
18414 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18416 * process.c (Fformat_network_address): Use local var for size,
18419 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18421 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18422 * data.c (atof): Remove decl; no longer used or needed.
18423 (digit_to_number): Move to lread.c.
18424 (Fstring_to_number): Use new string_to_number function, to be
18425 consistent with how the Lisp reader treats infinities and NaNs.
18426 Do not assume that floating-point numbers represent EMACS_INT
18427 without losing information; this is not true on most 64-bit hosts.
18428 Avoid double-rounding errors, by insisting on integers when
18429 parsing non-base-10 numbers, as the documentation specifies.
18430 * lisp.h (string_to_number): New decl, replacing ...
18431 (isfloat_string): Remove.
18432 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18433 (read1): Do not accept +. and -. as integers; this
18434 appears to have been a coding error. Similarly, do not accept
18435 strings like +-1e0 as floating point numbers. Do not report
18436 overflow for integer overflows unless the base is not 10 which
18437 means we have no simple and reliable way to continue.
18438 Break out the floating-point parsing into a new
18439 function string_to_number, so that Fstring_to_number parses
18440 floating point numbers consistently with the Lisp reader.
18441 (digit_to_number): Move here from data.c. Make it static inline.
18442 (E_CHAR, EXP_INT): Remove, replacing with ...
18443 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18444 (string_to_number): New function, replacing isfloat_string.
18445 This function checks for valid syntax and produces the resulting
18446 Lisp float number too. Rework it so that string-to-number
18447 no longer mishandles examples like "1.0e+". Use strtoumax,
18448 so that overflow for non-base-10 numbers is reported only when
18449 there's no portable and simple way to convert to floating point.
18451 * textprop.c (set_text_properties_1): Rewrite for clarity,
18452 and to avoid GCC warning about integer overflow.
18454 * intervals.h (struct interval): Use EMACS_INT for members
18455 where EMACS_UINT might cause problems. See
18456 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18457 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18458 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18460 (offset_intervals): Tell GCC not to worry about length overflow
18461 when negating a negative length.
18463 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18464 (overrun_check_free): Likewise.
18466 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18467 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18470 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18471 (gnutls_make_error): Rename local to avoid shadowing.
18472 (gnutls_emacs_global_deinit): ifdef out; not used.
18473 (Fgnutls_boot): Use const for pointer to readonly storage.
18474 Comment out unused local. Fix pointer signedness problems.
18476 * lread.c (openp): Don't stuff size_t into an 'int'.
18477 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18478 about possible signed overflow.
18480 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18481 (GDK_KEY_g): Don't define if already defined.
18482 (xg_prepare_tooltip): Avoid pointer signedness problem.
18483 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18485 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18486 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18488 * xfns.c (Fx_window_property): Simplify a bit,
18489 to make a bit faster and to avoid GCC 4.6.0 warning.
18490 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18492 * fns.c (internal_equal): Don't assume size_t fits in int.
18494 * alloc.c (compact_small_strings): Tighten assertion a little.
18496 Replace pEd with more-general pI, and fix some printf arg casts.
18497 * lisp.h (pI): New macro, generalizing old pEd macro to other
18498 conversion specifiers. For example, use "...%"pI"d..." rather
18499 than "...%"pEd"...".
18500 (pEd): Remove. All uses replaced with similar uses of pI.
18501 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18502 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18503 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18504 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18505 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18506 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18507 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18509 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18510 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18511 * print.c (safe_debug_print, print_object): Likewise.
18512 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18514 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18515 avoiding the 0 flag, which is not portable.
18516 * process.c (Fmake_network_process): Use pI to avoid cast.
18517 * region-cache.c (pp_cache): Likewise.
18518 * xdisp.c (decode_mode_spec): Likewise.
18519 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18520 behavior on 64-bit hosts with printf arg.
18521 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18522 (x_stop_queuing_selection_requests): Likewise.
18523 (x_get_window_property): Don't truncate byte count to an 'int'
18526 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18527 here, since it parses constructs like leading '-' and spaces,
18528 which are not wanted; and it overflows with large numbers.
18529 Instead, simply match F[0-9]+, which is what is wanted anyway.
18531 * alloc.c: Remove unportable assumptions about struct layout.
18532 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18533 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18534 (allocate_vectorlike, make_pure_vector): Use the new macros,
18535 plus offsetof, to remove unportable assumptions about struct layout.
18536 These assumptions hold on all porting targets that I know of, but
18537 they are not guaranteed, they're easy to remove, and removing them
18538 makes further changes easier.
18540 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18541 This doesn't fix a bug but makes the code clearer.
18542 (string_overrun_cookie): Now const. Use initializers that
18543 don't formally overflow signed char, to avoid warnings.
18544 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18545 can cause Emacs to crash when string overrun checking is enabled.
18546 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18547 multiple of sizeof (EMACS_INT); it need not be, if
18548 alignof(EMACS_INT) < sizeof (EMACS_INT).
18549 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18551 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
18553 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
18555 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18557 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18558 supposed to be handshaking. (Bug#8556)
18559 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18561 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18563 * lisp.h (Qdebug): List symbol.
18564 * eval.c (Qdebug): Restore global linkage.
18565 * keyboard.c (debug-on-event): New variable.
18566 (handle_user_signal): Break into debugger when debug-on-event
18567 matches the current signal symbol.
18569 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18571 * alloc.c (check_sblock, check_string_bytes)
18572 (check_string_free_list): Convert to standard C.
18574 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18576 * w32.c (emacs_gnutls_push): Fix typo.
18578 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18580 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18581 "cast to pointer from integer of different size".
18583 Improve doprnt and its use in verror. (Bug#8545)
18584 * doprnt.c (doprnt): Document the set of format control sequences
18585 supported by the function. Use SAFE_ALLOCA instead of always
18588 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18589 is one byte too soon. Don't use xrealloc; instead xfree and
18592 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18594 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18597 * gnutls.c: Renamed global_initialized to
18598 gnutls_global_initialized. Added internals for the
18599 :verify-hostname-error, :verify-error, and :verify-flags
18600 parameters of `gnutls-boot' and documented those parameters in the
18601 docstring. Start callback support.
18602 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18603 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18604 on error. Return error code.
18605 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18606 (emacs_gnutls_read): Likewise.
18607 (Fgnutls_boot): Return handshake error code.
18608 (emacs_gnutls_handle_error): New function.
18609 (wsaerror_to_errno): Likewise.
18611 * w32.h (emacs_gnutls_pull): Add prototype.
18612 (emacs_gnutls_push): Likewise.
18614 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
18615 (emacs_gnutls_push): Likewise.
18617 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
18619 * process.c (wait_reading_process_output): Check if GnuTLS
18620 buffered some data internally if no FDs are set for TLS
18623 * makefile.w32-in (OBJ2): Add gnutls.$(O).
18624 (LIBS): Link to USER_LIBS.

18629 * xdisp.c (handle_single_display_spec): Rename the
18630 display_replaced_before_p argument into display_replaced_p, to
18631 make it consistent with the commentary. Fix typos in the
18634 * textprop.c (syms_of_textprop): Remove dead code.

18640 to changes in oldXMenu/XMenu.h from 2011-04-16.
18641 <menu_help_message, prev_menu_help_message>: Constify.
18642 (IT_menu_make_room): menu->help_text is now `const char **';
18645 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
18646 to changes in oldXMenu/XMenu.h from 2011-04-16.
18647 (struct XMenu): Declare `help_text' `const char **'.

18658 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
18660 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
18663 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
18664 changes in globals.h immediately force recompilation.
18665 (TAGS): Depend on $(CURDIR)/m/intel386.h and
18666 $(CURDIR)/s/ms-w32.h.

18909 ns_descriptor_to_entity that were caused by using free to
18910 deallocate memory blocks that were allocated by xmalloc (via
18911 xstrdup). This caused Emacs to crash when compiled with

18931 (emacs_read, emacs_write): Use it.
18932 * process.c (send_process): Adjust to the new signatures of
18933 emacs_write and emacs_gnutls_write. Do not attempt to store

19136 * fns.c (weak_hash_tables): Now static.
19138 * fileio.c: Make symbols static if they're not exported.
19139 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

19153 * lisp.h (fatal_error_signal_hook): Remove decl.
19154 (fatal_error_signal): Declare only if FLOAT_CATCH_SIGKILL.

19157 * editfns.c, lisp.h (get_operating_system_release): Remove.
19158 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
19159 worth the hassle of breaking this out.
19161 * xterm.c: Make symbols static if they're not exported.
19162 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
19163 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

19265 * buffer.c (buffer_count): Remove unused var.
19267 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

19274 * atimer.h (run_all_atimers): Remove; not exported.
19276 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19277 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19278 was inaccessible from Lisp.
19279 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19280 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19282 alloc.c: Import and export fewer symbols, and remove unused items.
19283 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19285 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19286 it's not optimized away by whole-program optimization.

19289 Declare only if BYTE_MARK_STACK.

19298 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
19299 (mark_backtrace): Define only if BYTE_MARK_STACK.
19300 * xdisp.c (message_enable_multibyte): Now static.
19302 Declare Lisp_Object Q* variables to be 'static' if not exported.
19303 This makes it easier for human readers (and static analyzers)
19304 to see whether these variables are used from other modules.
19305 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
19306 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
19307 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

19315 Remove decls of unexported vars.
19316 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19318 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19320 Make Emacs functions such as Fatom 'static' by default.
19321 This makes it easier for human readers (and static analyzers)
19322 to see whether these functions can be called from other modules.
19323 DEFUN now defines a static function. To make the function external
19324 so that it can be used in other C modules, use the new macro DEFUE.
19325 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19326 (Finit_image_library):
19327 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19328 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19329 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19330 Remove decls, since these functions are now static.
19331 (Funintern, Fget_internal_run_time): New decls, since these functions
19332 were already external.
19334 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19335 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

19341 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19342 Mark functions with DEFUE instead of DEFUN,
19343 if they are used in other modules.
19344 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19345 decls for now-static functions.
19346 * buffer.h (Fdelete_overlay): Remove decl.
19347 * callproc.c (Fgetenv_internal): Mark as internal.

19356 * image.c (Finit_image_library): New forward static decl.
19357 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19358 * intervals.h (Fprevious_property_change):
19359 (Fremove_list_of_text_properties): Remove decls.
19360 * keyboard.c (Fthis_command_keys): Remove decl.
19361 (Fcommand_execute): New forward static decl.

19382 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19384 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19385 when at ZV. (Bug#8487)
19387 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19389 * charset.c (Fclear_charset_maps): Use xfree instead of free.

19392 * sound.c (sound_cleanup, alsa_close): Likewise.
19393 * termcap.c (tgetent): Likewise.
19394 * xfns.c (x_default_font_parameter): Likewise.
19395 * xsettings.c (read_and_apply_settings): Likewise.
19397 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19398 (overrun_check_free): Protoize.
19400 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19402 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19403 since callers should never pass a negative size.
19404 Change the signature to match that of plain 'read' and 'write'; see
19405 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19406 * lisp.h: Update prototypes of emacs_write and emacs_read.
19408 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19410 * xdisp.c (redisplay_window): Don't try to determine the character
19411 position of the scroll margin if the window start point w->startp
19412 is outside the buffer's accessible region. (Bug#8468)
19414 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19416 Fix write-region and its subroutines for buffers > 2GB.
19417 * fileio.c (a_write, e_write): Modify declaration of arguments and
19418 local variables to support buffers larger than 2GB.
19419 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19421 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19422 argument, local variables, and return value.
19424 * lisp.h: Update prototypes of emacs_write and emacs_read.
19426 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19428 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19430 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19432 Fix more problems found by GCC 4.6.0's static checks.
19434 * xdisp.c (vmessage): Use a better test for character truncation.
19436 * charset.c (load_charset_map): <, not <=, for optimization,
19437 and to avoid potential problems with integer overflow.
19438 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19439 * casetab.c (set_identity, shuffle): Likewise.
19440 * editfns.c (Fformat): Likewise.
19441 * syntax.c (skip_chars): Likewise.
19443 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19444 This also lets GCC 4.6.0 generate slightly better loop code.
19446 * callint.c (Fcall_interactively): <, not <=, for optimization.
19447 (Fcall_interactively): Count the number of arguments produced,
19448 not the number of arguments given. This is simpler and lets GCC
19449 4.6.0 generate slightly better code.
19451 * ftfont.c: Distingish more carefully between FcChar8 and char.
19452 The previous code passed unsigned char * to a functions like
19453 strlen and xstrcasecmp that expect char *, which does not
19454 conform to the C standard.
19455 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19456 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19457 char * when the C standard requires it.
19459 * keyboard.c (read_char): Remove unused var.
19461 * eval.c: Port to Windows vsnprintf (Bug#8435).
19462 Include <limits.h>.
19463 (SIZE_MAX): Define if the headers do not.
19464 (verror): Do not give up if vsnprintf returns a negative count.
19465 Instead, grow the buffer. This ports to Windows vsnprintf, which
19466 does not conform to C99. Problem reported by Eli Zaretskii.
19467 Also, simplify the allocation scheme, by avoiding the need for
19468 calling realloc, and removing the ALLOCATED variable.
19470 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19472 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19473 But keep the doprint source code for now, as we might revamp it
19474 and use it again (Bug#8435).
19475 * lisp.h (doprnt): Remove.
19476 * Makefile.in (base_obj): Remove doprnt.o.
19477 * deps.mk (doprnt.o): Remove.
19479 error: Print 32- and 64-bit integers portably (Bug#8435).
19480 Without this change, on typical 64-bit hosts error ("...%d...", N)
19481 was used to print both 32- and 64-bit integers N, which relied on
19482 undefined behavior.
19483 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19484 * lisp.h (error, verror): Mark as printf-like functions.
19485 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19486 Report overflow in size calculations when allocating printf buffer.
19487 Do not truncate output string at its first null byte.
19488 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19489 Truncate the output at a character boundary, since vsnprintf does not
19491 * charset.c (check_iso_charset_parameter): Convert internal
19492 character to string before calling 'error', since %c now has the
19494 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19495 overflow when computing char to be passed to 'error'. Do not
19496 pass Lisp_Object to 'error'; pass the integer instead.
19497 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19498 formatted with plain %d.
19500 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19502 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19504 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19506 * xterm.c (x_catch_errors): Remove duplicate declaration.
19508 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19510 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19512 2011-04-10 Jim Meyering <meyering@redhat.com>
19514 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19515 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19516 return ssize_t not "int", and use size_t as the buffer length.
19517 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19518 * gnutls.h: Update declarations.
19519 * process.c (read_process_output): Use ssize_t, to match.
19520 (send_process): Likewise.
19522 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19524 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19526 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19528 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19529 Use unsigned char, to match FcChar8 type definition.
19531 * xterm.c (handle_one_xevent):
19532 * xmenu.c (create_and_show_popup_menu):
19533 * xselect.c (x_decline_selection_request)
19534 (x_reply_selection_request): Avoid type-punned deref of X events.
19536 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19538 Fix some uses of `int' instead of EMACS_INT.
19539 * search.c (string_match_1, fast_string_match)
19540 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19541 (scan_buffer, find_next_newline_no_quit)
19542 (find_before_next_newline, search_command, Freplace_match)
19543 (Fmatch_data): Make some `int' variables be EMACS_INT.
19545 * xdisp.c (display_count_lines): 3rd argument and return value now
19546 EMACS_INT. All callers changed.
19547 (pint2hrstr): Last argument is now EMACS_INT.

19565 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19566 (encode_invocation_designation): Last argument P_NCHARS is now
19568 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19569 (produce_chars): from_nchars and to_nchars are now EMACS_INT.

19592 instead of using internal_with_output_to_temp_buffer.
19593 (Qhelp_form_show): New var.
19594 (syms_of_keyboard): Use DEFSYM macro.
19596 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19609 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19611 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19613 Fix more problems found by GCC 4.6.0's static checks.
19615 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

19619 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19621 * xdisp.c (vmessage): Mark as a printf-like function.
19623 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

19630 to system-supplied API.
19632 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19634 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19635 This avoids several warnings with gcc -Wstrict-overflow.
19636 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19637 directly, rather than having caller test rule sign. This avoids
19638 some unnecessary tests.
19639 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19640 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19641 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19643 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19644 (xfont_open): Avoid unnecessary tests.
19646 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19648 * composite.h, composite.c (composition_gstring_put_cache):
19649 Use EMACS_INT, not int, for length.
19651 * composite.h (COMPOSITION_DECODE_REFS): New macro,
19652 breaking out part of COMPOSITION_DECODE_RULE.
19653 (COMPOSITION_DECODE_RULE): Use it.
19654 * composite.c (get_composition_id): Remove unused local vars,
19655 by using the new macro.
19657 * textprop.c (set_text_properties_1): Change while to do-while,
19658 since the condition is always true at first.
19660 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19661 (interval_deletion_adjustment): Return unsigned value.
19664 * process.c (list_processes_1, create_pty, read_process_output):
19665 (exec_sentinel): Remove vars that were set but not used.
19666 (create_pty): Remove unnecessary "volatile"s.
19667 (Fnetwork_interface_info): Avoid possibility of int overflow.

19680 * print.c (print_error_message): Avoid int overflow.
19682 * font.c (font_list_entities): Redo for clarity,
19683 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19685 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19686 (font_score): Avoid potential overflow in diff calculation.
19688 * fns.c (substring_both): Remove var that is set but not used.
19689 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19691 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19693 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19694 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19695 can always succeed if overflow has undefined behavior.
19697 * search.c (boyer_moore, wordify): Remove vars set but not used.
19698 (wordify): Omit three unnecessary tests.
19700 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19701 All callers changed. This avoids the need for an unused var.
19703 * casefiddle.c (casify_region): Remove var that is set but not used.
19705 * dired.c (file_name_completion): Remove var that is set but not used.
19707 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19709 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19710 (Finsert_file_contents): Remove unnecessary code checking fd.
19712 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19713 Check for integer overflow on size calculations.
19715 * buffer.c (Fprevious_overlay_change): Remove var that is set
19718 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19719 Remove vars that are set but not used.
19720 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19721 (timer_check_2): Mark vars as initialized.
19723 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19725 * image.c (lookup_image): Remove var that is set but not used.
19726 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19728 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19729 that are set but not used.
19731 * xfns.c (make_invisible_cursor): Don't return garbage
19732 if XCreateBitmapFromData fails (Bug#8410).
19734 * xselect.c (x_get_local_selection, x_handle_property_notify):
19735 Remove vars that are set but not used.
19737 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19738 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19740 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19741 Remove var that is set but not used.
19742 (scroll_bar_windows_size): Now size_t, not int.
19743 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19744 Check for overflow.
19746 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19747 (map_tty_color) [!defined MSDOS]: Likewise.
19749 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19751 * coding.c: Remove vars that are set but not used.
19752 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19753 All callers changed.
19754 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19755 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19756 (decode_coding_charset): Remove vars that are set but not used.
19758 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19759 that is set but not used.
19761 * print.c (print_object): Remove var that is set but not used.
19763 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19764 The gnulib version avoids calling malloc in the usual case,
19765 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19766 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19767 * filelock.c (current_lock_owner): Likewise.
19768 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19769 * sysdep.c: Include allocator.h, careadlinkat.h.
19770 (emacs_no_realloc_allocator): New static constant.
19771 (emacs_readlink): New function.
19772 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19773 ../lib/careadlinkat.h.
19775 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19777 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19778 first non-nil return value).
19780 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
19782 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
19783 if not defined (Bug#8403).
19785 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19787 * xdisp.c (display_count_lines): Remove parameter `start',
19788 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19789 (get_char_face_and_encoding): Remove parameter `multibyte_p',
19790 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19792 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19793 and thereabouts. All callers changed.
19794 (get_per_char_metric): Remove parameter `f', unused since
19795 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19797 2011-04-02 Jim Meyering <meyering@redhat.com>
19799 do not dereference NULL upon failed strdup
19800 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19801 (ns_get_family): Likewise.
19803 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19805 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19807 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19809 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19812 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19814 Add lexical binding.
19816 * window.c (Ftemp_output_buffer_show): New fun.
19817 (Fsave_window_excursion):
19818 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19820 * lread.c (lisp_file_lexically_bound_p): New function.
19821 (Fload): Bind Qlexical_binding.
19822 (readevalloop): Remove `evalfun' arg.
19823 Bind Qinternal_interpreter_environment.
19824 (Feval_buffer): Bind Qlexical_binding.
19825 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19827 (syms_of_lread): Declare `lexical-binding'.
19829 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19831 * keyboard.c (eval_dyn): New fun.
19832 (menu_item_eval_property): Use it.
19834 * image.c (parse_image_spec): Use Ffunctionp.
19836 * fns.c (concat, mapcar1): Accept byte-code-functions.
19838 * eval.c (Fsetq): Handle lexical vars.
19839 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19840 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19841 (FletX, Flet): Obey lexical binding.
19842 (Fcommandp): Handle closures.
19843 (Feval): New `lexical' arg.
19844 (eval_sub): New function extracted from Feval. Use it almost
19845 everywhere where Feval was used. Look up vars in lexical env.
19847 (Ffunctionp): Move from subr.el.
19848 (Ffuncall): Handle closures.
19849 (apply_lambda): Remove `eval_flags'.
19850 (funcall_lambda): Handle closures and new byte-code-functions.
19851 (Fspecial_variable_p): New function.
19852 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19853 but without exporting it to Lisp.
19855 * doc.c (Fdocumentation, store_function_docstring):
19856 * data.c (Finteractive_form): Handle closures.
19858 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19861 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19863 (exec_byte_code): New function extracted from Fbyte_code to handle new
19864 calling convention for byte-code-functions. Add new byte-codes.
19866 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19868 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19870 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19872 * xdisp.c (redisplay_internal): Fix prototype.
19874 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19876 * xdisp.c (SCROLL_LIMIT): New macro.
19877 (try_scrolling): Use it when setting scroll_limit.
19878 Limit scrolling to 100 screen lines.
19879 (redisplay_window): Even when falling back on "recentering",
19880 position point in the window according to scroll-conservatively,
19881 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19883 (try_scrolling): When point is above the window, allow searching
19884 as far as scroll_max, or one screenful, to compute vertical
19885 distance from PT to the scroll margin position. This prevents
19886 try_scrolling from unnecessarily failing when
19887 scroll-conservatively is set to a value slightly larger than the
19888 window height. Clean up the case of PT below the margin at bottom
19889 of window: scroll_max can no longer be INT_MAX. When aggressive
19890 scrolling is in use, don't let point enter the opposite scroll
19891 margin as result of the scroll.
19892 (syms_of_xdisp) <scroll-conservatively>: Document the
19893 threshold of 100 lines for never-recentering scrolling.
19895 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19897 * dispextern.h (move_it_by_lines):
19898 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
19899 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
19900 (message_log_check_duplicate): Remove parameters `prev_bol' and
19901 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19902 (redisplay_internal): Remove parameter `preserve_echo_area',
19903 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19905 * indent.c (Fvertical_motion):
19906 * window.c (window_scroll_pixel_based, Frecenter):
19907 Don't pass `need_y_p' to `move_it_by_lines'.
19909 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19911 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19912 steal a few bits to be more compact.
19913 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19914 Remove unneeded casts.
19916 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19918 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19920 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19921 binding" message (bug#7967).
19923 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19925 Fix more problems found by GCC 4.6.0's static checks.
19927 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19928 Remove unused local var.
19930 * editfns.c (Fmessage_box): Remove unused local var.
19932 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19933 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19934 Omit unused local vars.
19935 * window.c (shrink_windows): Omit unused local var.
19936 * menu.c (digest_single_submenu): Omit unused local var.
19937 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19938 Omit unused local var.
19940 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19941 Don't assume string length fits in int.
19942 (keyremap_step, read_key_sequence): Use size_t for sizes.
19943 (read_key_sequence): Don't check last_real_key_start redundantly.
19945 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19946 instead of alloca (Bug#8344).
19948 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19949 (Fbacktrace_frame): Don't assume nframes fits in int.
19951 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19953 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19956 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19958 * cm.c (calccost): Turn while-do into do-while, for clarity.
19960 * keyboard.c (syms_of_keyboard): Use the same style as later
19961 in this function when indexing through an array. This also
19962 works around GCC bug 48267.
19964 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19966 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19968 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19969 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19971 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19972 This avoids undefined behavior on integer overflow, and is a bit
19973 more convenient anyway since it is compared to a size_t variable.
19975 Variadic C functions now count arguments with size_t, not int.
19976 This avoids an unnecessary limitation on 64-bit machines, which
19977 caused (substring ...) to crash on large vectors (Bug#8344).
19978 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19979 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
19980 All variadic functions and their callers changed accordingly.

19987 * fns.c (concat): Likewise.
19988 * frame.c (x_set_frame_parameters): Likewise.
19989 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19990 0 if not found, not -1. All callers changed.
19992 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19993 (stack_copy_size): Now size_t, not int.
19994 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19996 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19998 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19999 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20200 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20202 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20203 unconditionally since it does the check itself.
20205 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20207 Fix more problems found by GCC 4.5.2's static checks.
20209 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20210 the first time through the loop, since we know p0 < p1 then.
20211 This also avoids a gcc -Wstrict-overflow warning.
20213 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20214 leading to a memory leak, possible in functions like
20215 load_charset_map_from_file that can allocate an unbounded number
20216 of objects (Bug#8318).
20218 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20219 that could (at least in theory) be that large.
20221 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20222 This is less likely to overflow, and avoids undefined behavior if
20223 overflow does occur. All callers changed. Use strtoul to scan
20224 for the unsigned long integer.
20225 (pint2hrstr): Simplify and tune code slightly.
20226 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20241 * process.c (Fmake_network_process): Use socklen_t, not int,
20242 where POSIX says socklen_t is required in portable programs.
20243 This fixes a porting bug on hosts like 64-bit HP-UX, where
20244 socklen_t is wider than int (Bug#8277).
20245 (Fmake_network_process, server_accept_connection):
20246 (wait_reading_process_output, read_process_output):
20249 * process.c: Rename or move locals to avoid shadowing.

20259 Make tparam.h and terminfo.c consistent.
20260 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20261 Include tparam.h instead, since it declares them.
20262 * cm.h (PC): Remove extern decl; tparam.h now does this.
20263 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20264 * terminfo.c: Include tparam.h, to check interfaces.
20265 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20266 (tparam): Adjust signature to match interface in tparam.h;
20267 this removes some undefined behavior. Check that outstring and len
20268 are zero, which they always are with Emacs.
20269 * tparam.h (PC, BC, UP): New extern decls.
20271 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20272 (xftfont_open): Rename locals to avoid shadowing.

20290 (composition_update_it): Mark var as initialized.
20291 (find_automatic_composition): Mark vars as initialized,
20292 with a FIXME (Bug#8290).

20298 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20299 to avoid shadowing.

20311 Fix pointer signedness.
20312 (alsa_choose_format): Remove unused local var.
20313 (wav_play): Initialize a variable to 0, to prevent undefined
20314 behavior (Bug#8278).
20316 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20318 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20320 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20321 clobbering (Bug#8298).
20322 * sysdep.c (sys_subshell): Likewise.
20323 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20325 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20326 This should get cleaned up, so that child_setup has the
20327 same signature on all platforms.
20329 * callproc.c (call_process_cleanup): Now static.
20330 (relocate_fd): Rename locals to avoid shadowing.
20332 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20334 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20335 not to be necessary, and produces flickering.
20337 2011-03-20 Glenn Morris <rgm@gnu.org>
20339 * config.in: Remove file.
20341 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

20386 Define only if needed.
20388 * unexelf.c (unexec): Name an expression,
20389 to avoid gcc -Wbad-function-cast warning.
20390 Use a different way to cause a compilation error if anyone uses
20391 n rather than nn, a way that does not involve shadowing.
20392 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20394 * deps.mk (unexalpha.o): Remove; unused.

20451 * callint.c (quotify_arg, quotify_args): Now static.
20452 (Fcall_interactively): Rename locals to avoid shadowing.

20460 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20461 some of which prompt warnings from gcc -Wbad-function-cast.
20462 (Fformat_time_string, Fencode_time, Finsert_char):
20463 (Ftranslate_region_internal, Fformat):
20464 Rename or remove local vars to avoid shadowing.

20491 (Fmemory_limit): Cast sbrk's returned value to char *.
20493 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

20499 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20500 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20501 to use the following functions instead of these macros.
20502 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20503 EMACS_INT, since callers assume the returned value fits in int.
20504 (upcase1): Likewise, for UPCASE_TABLE.
20505 (uppercasep, lowercasep, upcase): New static inline functions.
20506 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20516 (regex_compile, re_match_2_internal): Mark locals as initialized.
20517 (RETALLOC_IF): Define only if needed.
20518 (WORDCHAR_P): Likewise. This one is never needed, but is used
20519 only in a comment talking about a compiler bug, so put inside
20520 the #if 0 of that comment.
20521 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20522 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

20548 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20549 New macros, so that the caller can use some names other than
20550 gcpro1, gcpro2, etc.
20551 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20553 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20554 argument, for consistency with GCPRO2_VAR, etc: it is now the
20555 prefix of the variable, not the variable itself. All uses
20557 * dired.c (directory_files_internal, file_name_completion):
20558 Rename locals to avoid shadowing.
20560 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20561 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20562 dired.c's scmp function, had undefined behavior.
20563 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20564 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20565 * buffer.h: ... to here, because these macros use current_buffer,
20566 and the new implementation with inline functions needs to have
20567 current_buffer in scope now, rather than later when the macros
20569 (downcase, upcase1): New static inline functions.
20570 (DOWNCASE, UPCASE1): Reimplement using these functions.
20571 This avoids undefined behavior in expressions like
20572 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20573 from race conditions in accessing the global variables
20574 case_temp1 and case_temp2.
20575 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20576 * lisp.h (case_temp1, case_temp2): Remove their decls.
20577 * character.h (ASCII_CHAR_P): Move from here ...
20578 * lisp.h: ... to here, so that the inline functions mentioned
20579 above can use them.

20583 * fileio.c (file_name_as_directory, directory_file_name):

20586 (file_name_as_directory): Use const pointers when appropriate.
20587 (Fexpand_file_name): Likewise. In particular, newdir might
20588 point at constant storage, so make it a const pointer.
20589 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20590 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20592 (Fset_file_times, Finsert_file_contents, auto_save_error):

20597 to avoid shadowing.
20599 * marker.c (bytepos_to_charpos): Remove; unused.
20601 * lisp.h (verify_bytepos, count_markers): New decls,
20602 so that gcc does not warn that these functions aren't declared.
20604 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20605 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20606 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20607 (copy_text): Remove unused local var.

20610 (lock_file_1): Rename local to avoid shadowing.
20612 * buffer.c (fix_overlays_before): Mark locals as initialized.
20613 (fix_start_end_in_overlays): Likewise. This function should be
20614 simplified by using pointers-to-pointers, but that's a different

20617 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20618 (report_overlay_modification): Rename locals to avoid shadowing.

20623 to suppress a gcc -Wclobbered warning that does not seem to be right.
20624 (MAXPATHLEN): Define only if needed.
20626 * process.c (serial_open, serial_configure): Move decls from here ...
20627 * systty.h: ... to here, so that they can be checked.
20629 * fns.c (get_random, seed_random): Move extern decls from here ...
20630 * lisp.h: ... to here, so that they can be checked.
20632 * sysdep.c (reset_io): Now static.

20793 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
