3 Use faccessat, not access, when checking file permissions (Bug#12632).
4 This fixes a bug that has been present in Emacs since its creation.
5 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
6 which must set some sort of record. (Torek's bug report was against
7 a predecessor of GNU Emacs, but GNU Emacs happened to have the
8 same common flaw.) See Torek's Usenet posting
9 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
10 Posted: Fri Apr 8 14:18:56 1983.
11 * Makefile.in (LIB_EACCESS): New macro.
13 * callproc.c (init_callproc):
14 * charset.c (init_charset):
15 * fileio.c (check_existing, check_executable, check_writable)
17 * lread.c (openp, load_path_check):
18 * process.c (allocate_pty):
20 Use effective UID when checking permissions, not real UID.
21 * callproc.c (init_callproc):
22 * charset.c (init_charset):
23 * lread.c (load_path_check, init_lread):
24 Test whether directories are accessible, not merely whether they exist.
25 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
26 * fileio.c (check_existing, check_executable, check_writable)
28 Use symbolic names instead of integers for the flags, as they're
30 (check_writable): New arg AMODE. All uses changed.
32 (Ffile_readable_p): Use faccessat, not stat + open + close.
33 (Ffile_writable_p): No need to call check_existing + check_writable.
34 Just call check_writable and then look at errno. This saves a syscall.
35 dir should never be nil; replace an unnecessary runtime check
36 with an eassert. When checking the parent directory of a nonexistent
37 file, check that the directory is searchable as well as writable, as
38 we can't create files in unsearchable directories.
39 (file_directory_p): New function, which uses 'stat' on most platforms
40 but faccessat with D_OK (for efficiency) if WINDOWSNT.
41 (Ffile_directory_p, Fset_file_times): Use it.
42 (file_accessible_directory_p): New function, which uses a single
43 syscall for efficiency.
44 (Ffile_accessible_directory_p): Use it.
45 * xrdb.c (file_p): Use file_directory_p.
46 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
47 * lread.c (openp): When opening a file, use fstat rather than
48 stat, as that avoids a permissions race. When not opening a file,
49 use file_directory_p rather than stat.
50 (dir_warning): First arg is now a usage string, not a format.
51 Use errno. All uses changed.
52 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
53 that merely introduced a race.
54 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
55 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
56 and similarly for the other O_* flags.
57 * w32.c (sys_faccessat): Rename from sys_access and switch to
58 faccessat's API. All uses changed.
59 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
60 (magic_db): Rename from magic_file_p.
61 (magic_db, search_magic_path): Return an XrmDatabase rather than a
62 char *, so that we don't have to test for file existence
63 separately from opening the file for reading. This removes a race
64 fixes a permission-checking problem, and simplifies the code.
66 (file_p): Remove; no longer needed.
68 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
70 Omit glyphs initialization at startup.
71 * dispnew.c (glyphs_initialized_initially_p): Remove.
72 (adjust_frame_glyphs_initially): Likewise. Adjust users.
73 (Fredraw_frame): Move actual code from here...
74 (redraw_frame): ...to here. Add eassert. Adjust comment.
75 (Fredraw_display): Use redraw_frame.
76 * xdisp.c (clear_garbaged_frames): Likewise.
78 2012-11-13 Eli Zaretskii <eliz@gnu.org>
80 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
81 passed to pint2str and pint2hrstr to be at most the size of the
82 frame's decode_mode_spec_buffer. This avoids crashes with very
83 large values of FIELD_WIDTH argument to decode_mode_spec.
86 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
88 Fix a race with verify-visited-file-modtime (Bug#12863).
89 Since at least 1991 Emacs has ignored an mtime difference of no
90 more than one second, but my guess is that this was to work around
91 file system bugs that were fixed long ago. Since the race is
92 causing problems now, let's remove that code.
93 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
94 whose time stamp is off by no more than a second. Insist that the
95 file time stamps match exactly.
97 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
99 * frame.h (struct frame): Convert external_tool_bar member to
100 1-bit unsigned bitfield.
101 * termhooks.h (struct terminal): Remove mouse_moved member since
102 all users are long dead. Adjust comment on mouse_position_hook.
104 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
106 Simplify by using FOR_EACH_FRAME here and there.
107 * frame.c (next_frame, prev_frame, other_visible_frames)
108 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
109 * w32term.c (x_window_to_scroll_bar): Likewise.
110 * window.c (window_list): Likewise.
111 * xdisp.c (x_consider_frame_title): Likewise.
112 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
113 * xfns.c (x_window_to_frame, x_any_window_to_frame)
114 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
115 * xmenu.c (menubar_id_to_frame): Likewise.
116 * xselect.c (frame_for_x_selection): Likewise.
117 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
118 (x_window_to_menu_bar): Likewise.
119 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
121 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
123 * data.c (Qdefalias_fset_function): Now static.
125 Another tweak to vectorlike_header change.
126 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
127 Remove, and replace all uses with ...
128 (next_in_free_list, set_next_in_free_list):
129 New functions, which respect C's aliasing rules better.
131 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
133 * window.c (list4i): Rename from 'quad'. All uses changed.
134 Needed because <sys/types.h> defines 'quad' on Solaris 10.
136 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
138 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
139 warning about mixing declarations and code in ISO C90.
141 2012-11-10 Martin Rudalics <rudalics@gmx.at>
143 * window.c (Fsplit_window_internal): Set combination limit of
144 new parent window to t iff Vwindow_combination_limit is t;
145 fixing a regression introduced with the change from 2012-09-22.
146 (Fset_window_combination_limit): Fix doc-string.
148 2012-11-10 Eli Zaretskii <eliz@gnu.org>
150 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
151 amount when the scroll margins are too large. When scrolling
152 backwards in the buffer, give up if cannot reach point or the
153 scroll margin within a reasonable number of screen lines. Fixes
154 point position in window under scroll-up/down-aggressively when
155 point is positioned many lines beyond the window top/bottom.
158 * ralloc.c (relinquish): If real_morecore fails to return memory
159 to the system, don't crash; instead, leave the last heap
160 unchanged and return. (Bug#12774)
162 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
164 * lisp.h (AUTOLOADP): New macro.
165 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
166 * data.c (Ffset): Remove special ad-advice-info handling.
167 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
169 (Finteractive_form): Simplify.

178 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
179 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
181 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
183 Fix recently introduced crash on MS-Windows (Bug#12839).
184 * w32term.h (struct scroll_bar): Use convenient header.
185 (SCROLL_BAR_VEC_SIZE): Remove.
186 * w32term.c (x_scroll_bar_create): Use VECSIZE.
188 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
190 Tweak last vectorlike_header change.
191 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
192 vectorlike object on the free list. This is introduced to avoid
193 some (but not all) pointer casting and aliasing problems, see
194 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
195 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
197 (xvectype, xvecsize): Use them to examine Lisp_Object values.
199 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
201 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
202 been removed, so remove them here also.
204 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
206 * doc.c (Fdocumentation): Handle new property
207 dynamic-docstring-function to replace the old ad-advice-info.
209 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
211 * fns.c (Qeql, hashtest_eq): Now static.
213 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
215 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
216 * fns.c (hashfn_eq, hashfn_eql, sxhash):
217 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
218 * buffer.c (compare_overlays): Use XLI rather than XHASH.
220 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
222 Use same hash function for hashfn_profiler as for hash_string etc.

224 * lisp.h (sxhash_combine): New inline function, with the contents
225 of the old SXHASH_COMBINE.
226 * profiler.c (hashfn_profiler): Use it, instead of having a
227 special hash function containing a comparison that always yields 1.
229 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
231 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
232 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
233 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
236 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
238 * image.c (xpm_make_color_table_h): Fix compiler error because
239 make_hash_table changed.
241 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
243 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
245 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
247 Use ad-hoc comparison function for the profiler's hash-tables.
248 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
249 (make_log): Use them.

311 (allocate_buffer): Use BUFFER_PVEC_INIT.
312 (live_vector_p): Adjust to match large vector.
313 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
314 * buffer.h (struct buffer): Add next member.
315 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
317 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

332 2012-11-07 Eli Zaretskii <eliz@gnu.org>
334 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
335 such as Scroll Lock, if the respective keys are treated as
336 function keys, not as modifiers. This avoids destroying non-ASCII
337 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
339 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
341 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
343 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
345 Restore some duplicate definitions (Bug#12814).
346 This undoes part of the 2012-11-03 changes. Some people build
347 with plain -g rather than with -g3, and they need the duplicate
348 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
349 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
350 Define as macros, as well as as enums or as constants.

355 to keypad keys (Bug#12816).
357 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
359 Minor adjustments of recently-changed frame functions.
360 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
361 known to be a frame (we're in the FRAMEP branch).
362 * lisp.h (Qframep): Remove decl. frame.h declares this.
363 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
364 since they're meant for Lisp fixnum values.
366 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
368 * window.c (Fwindow_combination_limit): Revert to the only
369 required argument and adjust docstring as suggested in
370 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
371 by Martin Rudalics <rudalics@gmx.at>.

415 (Fwindow_fringes): Use list3.
416 (Fwindow_scroll_bars): Use list4.
417 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
418 (Fwindow_combination_limit): Allow zero number of arguments.
420 2012-11-05 Eli Zaretskii <eliz@gnu.org>
422 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
424 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
425 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
426 file descriptor 2 for standard error. (Bug#12805)
428 2012-11-05 Chong Yidong <cyd@gnu.org>
430 * process.c (wait_reading_process_output): Revert previous change.
432 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
434 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
435 This removes code that has been obsolete since around 1990.
436 * callproc.c (Fcall_process):
438 * process.c (create_process):
439 * term.c (dissociate_if_controlling_tty):
440 Assume setsid exists.
441 * callproc.c (child_setup): Assume setpgid exists and behaves as
442 per POSIX.1-1988 or later.
443 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
444 * emacs.c (shut_down_emacs):

447 * msdos.c (setpgrp): Remove.
448 (tcgetpgrp, setpgid, setsid): New functions.
449 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.

454 Simplify by assuming __fpending.
455 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
456 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
457 Do not assume that __fpending's result fits in int.
459 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
461 Remove EMACS_OUTQSIZE+sleep hack.
462 * dispnew.c (update_frame_1): Remove hack for terminals slower
463 than 2400 bps, which throttled Emacs by having it sleep.
464 This code hasn't worked since at least 2007, when the multi-tty stuff
465 was added, and anyway those old terminals are long dead.
466 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
467 without the dispnew.c change, as dispnew.c doesn't include systty.h.
469 Fix data-loss with --version (Bug#9574).
470 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
471 as we can't assume that emacs_strerror is initialized, and strerror
473 (main): Invoke atexit earlier, to catch earlier instances of
474 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
476 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
478 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
479 (keyDown): Remap keypad keys to X11 virtual key codes.
481 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
483 Fix data-loss with --batch (Bug#9574).
484 * emacs.c: Include <close-stream.h>.
485 (close_output_streams): New function.
486 (main): Pass it to atexit, so that Emacs closes stdout and stderr
487 and handles errors appropriately.
488 (Fkill_emacs): Don't worry about flushing, as close_output_stream
491 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
492 The symptom is a diagnostic "GLib-WARNING **: In call to
493 g_spawn_sync(), exit status of a child process was requested but
494 SIGCHLD action was set to SIG_IGN and ECHILD was received by
495 waitpid(), so exit status can't be returned." The diagnostic
496 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
497 The real bug is a race condition between Emacs and glib: Emacs
498 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
499 so that glib can't find it. Work around the bug by invoking
500 waitpid only on subprocesses that Emacs itself creates.
501 * process.c (create_process, record_child_status_change):
502 Don't use special value -1 in pid field, as the caller now must
503 know the pid rather than having the callee infer it.
504 The inference was sometimes incorrect anyway, due to another race.
505 (create_process): Set new 'alive' member if child is created.
506 (process_status_retrieved): New function.
507 (record_child_status_change): Use it.
508 Accept negative 1st argument, which means to wait for the
509 processes that Emacs already knows about. Move special-case code
510 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
511 processes that have already been waited for, by testing and
512 clearing new 'alive' member.
513 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
514 now does this internally.
515 (handle_child_signal): Let record_child_status_change do all
516 the work, since we do not want to reap all exited child processes,
517 only the child processes that Emacs itself created.
518 * process.h (Lisp_Process): New boolean member 'alive'.
520 Omit duplicate definitions no longer needed with gcc -g3.
521 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
522 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
523 Define only as macros. There's no longer any need to also define
524 these symbols as enums or as constants, since we now assume
525 gcc -g3 when debugging.
527 2012-11-03 Eli Zaretskii <eliz@gnu.org>
529 * lisp.mk: Adjust comments to the fact that term/internal is now
530 loaded from loadup.el.
532 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
533 (msdos_fatal_signal): New function.
534 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
537 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
538 for GCC versions before 4.
539 (emacs_raise): Define to call msdos_fatal_signal.
541 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
542 iterator when starting in the middle of a display or overlay
545 2012-11-03 Chong Yidong <cyd@gnu.org>
547 * process.c (wait_reading_process_output): Clean up the last
550 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
552 * process.c (wait_reading_process_output): Avoid a race condition
553 with SIGIO delivery (Bug#11536).
555 2012-11-03 Chong Yidong <cyd@gnu.org>
557 * buffer.c (cursor_type): Untabify docstring.
559 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
561 * frame.h (struct frame): Drop can_have_scroll_bars member
562 which is meaningless for a long time. Adjust comments.
563 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
564 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
566 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
568 * window.c (decode_next_window_args): Update window arg after
569 calling decode_live_window and so fix crash reported at
570 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
571 by Juanma Barranquero <lekktu@gmail.com>.
572 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
573 * font.c (Ffont_at): Likewise.
575 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
577 * widget.c (resize_cb): New function.
578 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
579 (EmacsFrameResize): Check if all is up to date before changing frame
582 2012-11-02 Eli Zaretskii <eliz@gnu.org>
584 Implement backtrace output for fatal errors on MS-Windows.
585 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
586 (BACKTRACE_LIMIT_MAX): New macro.
587 (w32_backtrace): New function.
588 (emacs_abort): Use w32_backtrace when the user chooses not to
589 attach a debugger. Update the text of the abort dialog.
591 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
593 Window-related stuff cleanup here and there.
594 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
595 Use decode_any_window.
596 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
597 * xdisp.c (Fformat_mode_line): Likewise.
598 * font.c (Ffont_at): Use decode_live_window.
599 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
600 * window.c (decode_next_window_args): Likewise.
601 (decode_any_window): Remove static.
602 * window.h (decode_any_window): Add prototype.
603 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
604 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
607 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
609 Remove pad from struct input_event.
610 * termhooks.h (struct input_event): Remove padding field.
612 * keyboard.c (event_to_kboard): Simplify because frame_or_window
613 member is never cons for a long time. Adjust comment.
614 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
615 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
616 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
617 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
619 2012-11-01 Eli Zaretskii <eliz@gnu.org>
621 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
623 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
625 Fix crash when using Emacs as commit editor for git (Bug#12697).
626 * callproc.c (setpgrp): Remove macro, as we now use setpgid
627 and it is configured in conf_post.h.
628 (Fcall_process): Don't invoke both setsid and setpgid; the former
629 is enough, if it exists.
630 * callproc.c (Fcall_process, child_setup):
631 * process.c (create_process): Use setpgid.
632 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
634 * dispnew.c (init_display): Initialize the foreground group
635 if we are running a tty display.
636 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
637 * lisp.h (init_foreground_group): New decl.
638 * sysdep.c (inherited_pgroup): New static var.
639 (init_foreground_group, tcsetpgrp_without_stopping)
640 (narrow_foreground_group, widen_foreground_group): New functions.
641 (init_sys_modes): Narrow foreground group.
642 (reset_sys_modes): Widen foreground group.
644 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
646 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
648 2012-10-31 Martin Rudalics <rudalics@gmx.at>
650 * minibuf.c (read_minibuf): Restore current buffer since
651 choose_minibuf_frame calling Fset_frame_selected_window may
652 change it (Bug#12766).
654 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
656 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
658 2012-10-30 Kenichi Handa <handa@gnu.org>
660 * font.c (Ffont_at): If WINDOW is specified and it is not
661 displaying the current buffer, signal an error.
663 2012-10-29 Daniel Colascione <dancol@dancol.org>
665 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
666 In preparation for fixing bug#12739, move these functions from
669 * coding.h, coding.c: ... to here, and compile them only when
670 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
671 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
673 2012-10-28 Eli Zaretskii <eliz@gnu.org>
675 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
676 (timer_loop, getitimer, setitimer): Use it instead of
677 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
679 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
682 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
684 * nsterm.m (NO_APPDEFINED_DATA): New define.
685 (last_appdefined_event_data): New variable
686 (last_appdefined_event): Remove.
687 (ns_select): Initialize t from last_appdefined_event_data instead
688 of [last_appdefined_event data1].
689 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
690 remove last_appdefined_event (Bug#12698).
692 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
694 * frame.c (x_set_font): Catch internal error.
696 2012-10-27 Eli Zaretskii <eliz@gnu.org>
698 Avoid overflow in w32 implementation of interval timers.
699 When possible, for ITIMER_PROF count only times the main thread
701 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
702 'volatile ULONGLONG' types. All the other data which was
703 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
704 (GetThreadTimes_Proc): New typedef.
705 (w32_get_timer_time): New function, returns a suitable time value
707 (timer_loop): Enter critical section when accessing ULONGLONG
708 values of the itimer_data struct, as these accesses are no longer
709 atomic. Call 'w32_get_timer_time' instead of 'clock'.
710 Remove unused variable.
711 (init_timers): Initialize s_pfn_Get_Thread_Times.
712 (start_timer_thread): Don't assign itimer->caller_thread here.
713 (getitimer): Assign itimer->caller_thread here.
714 (setitimer): Always call getitimer to get the value of ticks_now.
715 (sys_spawnve): Avoid compiler warning about format mismatch.
717 2012-10-26 Eli Zaretskii <eliz@gnu.org>
719 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
720 mouse movement events if the menu bar is active. This avoids
721 producing a busy "hour-glass" cursor by Windows if the mouse
722 pointer is positioned over a tooltip shown for some menu item.
724 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
726 Don't assume process IDs fit in int.
727 * emacs.c (shut_down_emacs) [!DOS_NT]:
728 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
729 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
730 Use pid_t, not int, to store process IDs, as 'int'
731 is not wide enough on a few platforms (e.g., AIX and IRIX).
733 2012-10-23 Kenichi Handa <handa@gnu.org>
735 The following change is to make face-font-rescale-alist work
736 correctly for non-ASCII fonts.
738 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
739 (font_open_for_lface): Handle Vface_font_rescale_alist.
741 2012-10-23 Chong Yidong <cyd@gnu.org>
743 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
745 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
747 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
749 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
751 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
754 2012-10-21 Glenn Morris <rgm@gnu.org>
756 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
758 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
761 * frame.c (Fmouse_position, Fmouse_pixel_position):
762 * xdisp.c (produce_stretch_glyph):
763 Declare local vars only when they're needed.
764 This is clearer and avoids a warning on OpenBSD about unused vars.
765 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
766 This is safer, and avoids OpenBSD warnings about unused vars.
767 * keyboard.c (record_menu_key): Remove unnecessary decl.
768 (poll_timer): Define only if POLL_FOR_INPUT is defined.
769 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
770 as our definition clashes with OpenBSD's.
771 * xfaces.c (load_face_colors, check_lface_attrs)
772 (get_lface_attributes_no_remap, get_lface_attributes)
773 (lface_fully_specified_p, x_supports_face_attributes_p)
774 (tty_supports_face_attributes_p, face_fontset, realize_face)
775 (realize_x_face, realize_tty_face):
776 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
777 merely Lisp_Object *. This is more informative and avoids
778 a warning on OpenBSD about accessing beyond an object's size.
780 2012-10-20 Chong Yidong <cyd@gnu.org>
782 * lread.c (Fload): Doc fix (Bug#12592).
784 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
786 * font.c (Ffont_at): Fix previous change.
788 2012-10-19 Eli Zaretskii <eliz@gnu.org>
790 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
791 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
794 * alloc.c (NSTATICS): Decrease to 0x800.
796 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

804 FD_ISSET (Bug#12668).
806 2012-10-18 Daniel Colascione <dancol@dancol.org>
808 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
809 (staticpro): If we run out of staticpro slots, die with an
810 informative error instead of just calling emacs_abort.
812 2012-10-18 Martin Rudalics <rudalics@gmx.at>
814 Fix two flaws reported by Dmitry Antipov.

824 ($(BLD)/unexw32.$(O)):
825 ($(BLD)/fileio.$(O)):
826 ($(BLD)/dispnew.$(O)): Update dependencies.
828 * w32term.h (w32_initialize_display_info, initialize_w32_display):

839 * w32.c: Include w32select.h.
840 (sys_access, e_malloc, sys_select): Add prototypes.

843 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
845 * unexw32.c: Include lisp.h and w32.h.
847 * term.c [WINDOWSNT]: Include w32term.h.
849 * process.c [WINDOWSNT]: Add prototype of sys_select.
851 * fileio.c [WINDOWSNT]: Include w32.h.

855 * cygw32.c (Fcygwin_convert_path_to_windows)
856 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
857 Lisp_Object values. (Bug#12661)
859 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
860 to Lisp_Object. (Bug#12661)
862 2012-10-17 Kenichi Handa <handa@gnu.org>
864 * xdisp.c (reseat_1): Make the information stored in it->cmp_it

898 * window.c (Fwindow_end): Rewrite check whether cached position
899 can be used (Bug#12600).
900 (resize_frame_windows, grow_mini_window, shrink_mini_window):
901 Set windows_or_buffers_changed.
903 2012-10-15 Daniel Colascione <dancol@dancol.org>
905 * dbusbind.c: Fix cygw32 build break when compiling with dbus
906 enabled by undefining the symbol "interface", which the platform
907 headers define to something incompatible.
909 2012-10-14 Daniel Colascione <dancol@dancol.org>
911 * image.c (init_tiff_functions, init_imagemagick_functions)
912 (init_svg_functions): Fix cygw32 build break by using these
913 functions only when WINDOWSNT _and_ HAVE_NTGUI.

936 removed or renamed by some other process immediately after Emacs
937 writes it but before Emacs stats it. Do not assume that stat (or

940 rather than stat + fopen.
941 (pbm_read_file) [0]: Remove unused code with stat race.
942 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
943 Remove ineffective code with stat race.
945 2012-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
947 * doc.c (get_doc_string): Don't signal an error if the file is missing.
949 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
951 * nsterm.m (hold_event_q): New static variable.

960 2012-10-12 Juanma Barranquero <lekktu@gmail.com>
962 * makefile.w32-in ($(BLD)/w32select.$(O)): Update dependencies.
964 2012-10-12 Eli Zaretskii <eliz@gnu.org>
966 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
968 * fileio.c (check_existing): New function.
969 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
970 instead of calling 'stat', when what's needed is to check whether
971 a file exists. This avoids expensive system calls on MS-Windows.
974 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
976 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
977 determine whether a file exists and is not a directory.
979 * lisp.h (check_existing): Add prototype.
981 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
983 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

1013 Use bool for booleans.
1014 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
1015 as it's not a predicate. All uses changed. Omit unnecessary
1018 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
1020 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.
1021 (save_excursion_restore): Do not restore mark if it was not saved.
1023 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
1025 * marker.c (cached_modiff): EMACS_INT, not int.
1027 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
1028 instead of having a wrong decl.
1029 * nsmenu.m (waiting_for_input): Remove wrong decl.
1031 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>

1067 * process.c (wait_reading_process_output):
1068 Use unsigned for counter where wraparound-on-overflow is desired,
1069 since unsigned is guaranteed to have that behavior and signed is not.
1070 (read_char): Use ptrdiff_t for string length.
1071 (get_input_pending): Remove first argument, since it was always
1072 the same pointer-to-int (now pointer-to-boolean) &input_pending,
1073 and behave as if it had that value. Return new value of
1074 input_pending. All callers changed.
1075 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
1076 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
1078 * keymap.c (push_key_description): Omit last arg, which was always 1.
1079 All callers changed.
1081 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
1083 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

1098 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
1099 Don't include termopts.h.
1101 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
1103 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
1105 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
1107 * commands.h (immediate_quit): Remove duplicate decl.
1109 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
1111 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
1113 (nsfont_open): Remove setting of Vfonts_in_cache.
1114 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
1116 2012-10-09 Eli Zaretskii <eliz@gnu.org>
1118 * w32fns.c (w32_last_error): Change the return value to DWORD, to
1119 match what GetLastError returns. Explain why the function is
1122 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
1123 'is_tooltip_frame', to avoid confusion with its global namesake.
1125 2012-10-08 Daniel Colascione <dancol@dancol.org>
1127 * xdisp.c (start_hourglass): Call w32_note_current_window when
1128 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
1129 build that caused Emacs to display the hourglass cursor forever.
1131 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
1132 which is broken under remote desktop, calculate the number of
1133 colors available for a display based on the display's number of
1134 planes and number of bits per pixel per plane. (bug#10397).
1136 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
1138 * nsfont.m (Vfonts_in_cache): New variable.
1139 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
1140 are used. Add cached fonts to Vfonts_in_cache.
1141 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
1143 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
1145 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
1147 (FONT_H): Define after FRAME_H.
1148 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
1149 Update dependencies.
1151 * w32term.c: Remove leftover declaration of keyboard_codepage.
1153 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1155 * makefile.w32-in (FONT_H): Add $(FRAME_H).
1156 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
1157 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
1158 (GLOBAL_SOURCES): Add cygw32.c.
1159 ($(BLD)/unexw32.$(O)):
1161 ($(BLD)/w32console.$(O)):
1162 ($(BLD)/w32fns.$(O)):
1163 ($(BLD)/w32heap.$(O)):
1164 ($(BLD)/w32menu.$(O)):
1165 ($(BLD)/w32proc.$(O)): Add w32common.h.
1167 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
1169 (x_to_w32_color): Don't modify the argument, modify a copy instead.
1171 2012-10-08 Daniel Colascione <dancol@dancol.org>
1173 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
1174 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
1175 accidental message numbering hole. Change other messages to
1178 * w32select.h (HAVE_W32SELECT): Remove.
1180 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
1181 w32common.h instead of w32heap.h.
1183 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
1184 (get_allocation_unit, get_processor_type, get_w32_major_version)
1185 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1186 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1187 (OS_NT, os_subtype, cache_system_info): Move declarations to
1190 * w32heap.c: Include w32common.h.
1191 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
1192 (w32_minor_version, w32_build_number, w32_subtype):
1193 Remove duplicate definitions.
1195 * w32fns.c: Include w32common.h; include w32heap.h only in
1198 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
1199 Use `report_file_error' instead of `error' in order to better
1200 inform users of what went wrong. Increase NTGUI_UNICODE file
1201 dialog box file name length to 32k, the maximum allowed by the NT
1204 * w32common.h: New file.
1205 (ROUND_UP, ROUND_DOWN, get_page_size)
1206 (get_allocation_unit, get_processor_type, get_w32_major_version)
1207 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1208 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1209 (OS_NT, os_subtype, cache_system_info): Move here.
1211 * unexw32.c, unexcw.c: Include w32common.h.
1213 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1214 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1215 to call syms_of_w32select.
1217 * cygw32.h: Remove obsolete EXFUN declarations.
1219 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
1221 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
1222 of w32inevt.o from SOME_MACHINE_OBJECTS.
1224 2012-10-08 Daniel Colascione <dancol@dancol.org>
1226 * image.c: Permanent fix for JPEG compilation issue --- limit
1227 jpeglib `boolean' redefinition to Cygwin builds.
1229 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1231 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1233 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1236 2012-10-08 Daniel Colascione <dancol@dancol.org>
1238 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1239 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1240 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1241 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1242 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1243 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1244 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1245 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1246 now a supported configuration.
1248 * Makefile.in: consolidate image variables into LIBIMAGE; add
1249 W32_OBJ and W32_LIBS. Compile new files.
1252 (_DebPrint) declare tracing facility for W32 debugging. We need
1253 to unify tracing later.
1255 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1256 unconditional use of W32 Unicode functions. Cygwin runs only on
1257 100% Unicode operating systems.
1259 * cygw32.c: New file. Define Cygwin-specific facilities.
1260 (Fcygwin_convert_path_to_windows)
1261 (Fcygwin_convert_path_from_windows): New user functions for
1262 accessing Cygwin path-munging routines.
1264 * cygw32.h: New file.
1265 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1266 UTF-16LE strings temporarily inside non-Lisp-visible string
1269 (w32_strerror): Just what it says on the tin.
1271 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1272 also run for Cygwin; both systems have the same problem with using
1273 GUI facilities in a forked child. Also call syms_of_cygw32,
1274 syms_of_w32select in correct places.
1276 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1277 needs fork-then-exec for daemon launching.
1279 * font.h: Include frame.h.
1281 * image.c: Use the image library cache machinery only when we're
1282 compiling for native WINDOWSNT; Cygwin can use shared libraries
1283 like any other Unixlike system.
1285 * keyboard.c: Clarify a comment regarding the input loop.
1287 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1288 functions directly instead of trying to detect at runtime that our
1289 host operating system supports them. We make this change for two
1290 reasons: Cygwin lacks support for the multibyte character
1291 conversion functions used by the legacy menu code, and Cygwin
1292 never needs to rely on non-Unicode APIs.
1294 * unexw32.c (hinst): Declare extern.
1296 * w32.c: Change header order;
1297 (w32_strerror): Move to w32fns.c because we need it for
1298 non-WINDOWSNT builds.
1300 * w32.h: Add #error macro to make sure we don't include w32.h for
1301 Cygwin builds. Remove w32select declarations.
1303 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1304 w32fns.c. w32console.c is WINDOWSNT-only.
1306 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1307 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1309 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1310 (w32_major_version, w32_minor_version, w32_build_number)
1311 (os_subtype, sound_type): Define here
1312 (w32_defined_color): Make color parameter const for consistency
1313 with other _defined_color functions.
1314 (w32_createwindow): Unconditionally call w32_init_class instead of
1315 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1316 through the code is complex and unnecessary because class
1317 registration is practically free.
1318 (w32_name_of_message): New EMACSDEBUG-only function.
1319 (Fset_message_beep): Move here
1320 (Fx_open_connection): Require that the display name for Windows be
1321 "w32" for consistency, emacsclient disambiguation, and maybe, one
1322 day, multi-window-system support.
1323 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1324 Cygwin files for W32 GUI facilities, since these clearly don't
1325 expect Cygwin names.
1326 (_DebPrint): Define.
1327 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1328 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1329 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1330 (w32_last_error): Remove.
1332 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1334 * w32heap.c (syspage_mask): Declare here.
1335 (cache_system_info): Remove.
1337 * w32inevt.c (faked_key): Define globally, not statically.
1338 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1339 (w32_console_toggle_lock_key): Move to w32fns.c.
1341 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1343 * w32proc.c (_DebPrint): Move to w32fns.c.
1344 * w32select.c: Include string.h, stdio.h for Cygwin.
1345 * w32select.h: New File.
1347 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1349 (w32_message_fd): New variable. Under Cygwin, holds the file
1350 descriptor the system used to tell us about pending thread
1353 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1354 that prevented compilation under non-WINDOWSNT systems.
1356 (w32_initialize): Open /dev/windows and assign it to
1357 w32_message_fd. Provide w32 feature.
1359 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1360 (WM_EMACS_INPUT_READY): add.
1361 (prepend_msg, w32_message_fd): Declare globally.
1364 (keyboard_handle): Use only when WINDOWSNT.
1365 (notify_msg_ready): New function. Posts a message to the main
1366 thread's message queue under CYGWIN, which wakes up the main
1367 thread from select(2) by making the /dev/windows file descriptor
1368 ready. Under WINDOWSNT, it sets an event the same way the old
1371 (post, prepend_msg): Actually call notify_msg_ready instead of
1372 setting the input event directly.
1374 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1376 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1377 but it still has blocs in it, don't return it to the system,
1378 instead of aborting. (Bug#12402)
1380 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1382 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
1384 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
1385 MAC_OS_X_VERSION_10_6.
1386 (syms_of_nsterm): Remove comment about Panther and above for
1388 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
1389 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
1390 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
1392 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
1393 MAC_OS_X_VERSION_10_4.
1395 * nsmenu.m (fillWithWidgetValue:): Remove code for <
1396 MAC_OS_X_VERSION_10_2.
1398 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
1400 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
1401 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
1403 * nsterm.m (ns_in_resize): Remove (Bug#12479).
1404 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
1405 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
1406 Remove ns_in_resize check.
1407 (ns_clear_frame_area): Remove resize handle code.
1409 * nsfns.m (ns_in_resize): Remove.
1410 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
1411 Remove ns_in_resize check.
1413 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
1415 Improve sys_siglist detection.
1416 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1417 defined as a macro, as is done in Solaris.
1418 (sys_siglist_entries): New macro.
1419 (save_strsignal): Use it.
1420 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1421 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1423 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1425 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1426 fullscreen/Fullscreen.
1428 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1429 tobar_height is new.

1432 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1433 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
1434 (windowDidResize:): Check for correct window if old style fullscreen.
1435 Capitalize word in comment. Remove incorrect comment.
1436 (initFrameFromEmacs:): tbar_height renamed tibar_height.
1437 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
1438 error in drawing background.
1439 (toggleFullScreen:): Remove comment. Rearrange calls.
1440 Set toolbar values to zero, save old height in tobar_height.

1442 (canBecomeMainWindow): New function.
1444 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
1446 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1448 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1450 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1452 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1453 that time stamps of directories could also be changed.
1454 Don't request the too broad GENERIC_WRITE, only the more restrictive
1455 FILE_WRITE_ATTRIBUTES access rights.
1457 * fileio.c (Fset_file_times): Special-case ignoring errors for
1458 directories only on MSDOS, not on MS-Windows.
1460 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1462 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1464 2012-10-04 Eli Zaretskii <eliz@gnu.org>
1466 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
1467 see whether CreateFile failed.
1469 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1471 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1472 to avoid similar races.
1473 * keyboard.c (pending_signals): Now bool, not int.
1475 Port timers to OpenBSD, plus check for timer failures.
1476 OpenBSD problem reported by Han Boetes.
1477 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1479 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1480 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1481 like OpenBSD, which has timer_settime but does not declare it.
1482 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1483 whether to use itimerspec-related primitives. All uses of
1484 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1486 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1488 * profiler.c (handle_profiler_signal): Fix a malloc race
1489 that caused Emacs to hang on Fedora 17 when profiling Lisp.

1493 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1495 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1497 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1498 consistent with the change in return value of 'safe_strsignal'.
1500 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1502 Prefer plain 'static' to 'static inline' (Bug#12541).
1503 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1504 (bidi_set_sor_type, bidi_push_embedding_level)
1505 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

1510 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1511 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1512 Now 'static', not 'static inline'.
1514 Count overruns when profiling; change units to ns.
1515 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1516 Give extra weight to samples after overruns, to attempt to count
1517 the time more accurately.
1518 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1519 the underlying primitives nominally do ns.
1520 (Fprofiler_cpu_start): Document the change. Mention that
1521 the sampling intervals are only approximate.
1523 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1525 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1527 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1528 case for the special 0 coding-system.
1530 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1531 (Fmake_overlay): Remove redundant tests.
1532 (fix_start_end_in_overlays): Remove redundant recentering.
1534 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1536 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1537 Update dependencies.
1539 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1541 Fix a malloc race condition involving strsignal.
1542 A signal can arrive in the middle of a malloc, and Emacs's signal
1543 handler can invoke strsignal, which can invoke malloc, which is
1544 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1545 Fix it by altering the signal handler so that it does not invoke
1547 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1548 * process.c (status_message): Use const pointer, in case strsignal
1549 is #defined to safe_strsignal.
1550 * sysdep.c (sys_siglist, init_signals): Always define and
1551 initialize a substitute sys_siglist if the system does not define
1552 one, even if HAVE_STRSIGNAL.
1553 (safe_strsignal): Rename from strsignal. Always define,
1554 using sys_siglist. Return a const pointer.
1555 * syssignal.h (safe_strsignal): New decl.
1556 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1558 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1560 * w32proc.c (timer_loop): Fix code that waits for timer
1561 expiration, to avoid high CPU usage.
1563 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1565 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1566 (sweep_weak_table): Remove redundant prototypes.
1568 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1570 * emacs.c: Move the inclusion of TERM_HEADER after including
1571 windows.h on WINDOWSNT. This avoids compilation problems with
1574 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1576 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1577 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1578 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1579 as the previous version used 'void *'.
1581 * ralloc.c (ROUNDUP): Fix last change.
1582 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1585 * w32proc.c <disable_itimers>: New static flag.
1586 (init_timers): Initialize it to zero, after creating the critical
1587 sections used by the timer threads.
1588 (term_timers): Set to 1 before deleting the critical sections.
1589 (getitimer, setitimer): If disable_itimers is non-zero, return an
1590 error indication without doing anything. Reported by Fabrice
1591 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1592 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1594 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1597 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1598 term_ntproc after all the other bookkeeping, to get timers working
1599 as long as possible.
1601 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1603 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1604 Suggested by Juri Linkov in
1605 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1607 Prefer plain 'static' to 'static inline' (Bug#12541).
1608 With static functions, modern compilers inline pretty well by
1609 themselves; advice from programmers often hurts as much as it helps.
1610 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1611 this change shrinks the text size of the Emacs executable by 1.1%
1612 without affecting CPU significantly in my benchmark.
1613 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

1693 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1695 Revert the FOLLOW-SYMLINKS change for file-attributes.
1696 Doing it right would require several changes to Tramp, and there's
1697 not enough time to get that tested before the freeze today.
1698 * dired.c (directory_files_internal, Ffile_attributes):
1701 * frame.c (x_report_frame_params): Port better to wider ints.
1702 Do not assume that EMACS_UINT is the same width as uprintmax_t,
1703 or that pointers can be printed in 15 decimal digits.

1822 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
1824 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
1826 * w32.h (init_timers, term_timers): Add prototypes.
1828 2012-09-30 Kenichi Handa <handa@gnu.org>
1830 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
1831 to the buffer relocation which may be caused by ccl_driver.

1866 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
1867 (EmacsFSWindow): New interface for fullscreen.
1869 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
1871 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
1873 2012-09-30 Chong Yidong <cyd@gnu.org>
1875 * fns.c (Frandom): Doc fix.
1877 2012-09-30 Martin Rudalics <rudalics@gmx.at>
1879 * window.c (Vwindow_combination_limit): New default value.
1880 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
1882 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1884 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
1885 Suggested by Eli Zaretskii in
1886 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
1888 2012-09-30 Eli Zaretskii <eliz@gnu.org>
1890 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
1891 HAVE_TIMER_SETTIME is defined.
1893 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1895 Profiler improvements: more-accurate timers, overflow checks.
1896 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1897 signal.h, setjmp.h. Include systime.h instead.
1898 (saturated_add): New function.
1899 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
1900 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
1901 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
1903 (enum profiler_cpu_running): New enum.
1904 (profiler_cpu_running): Now of that enum type, not bool.
1905 All uses changed to store the new value.
1906 (handle_profiler_signal): Rename from sigprof_handler_1,
1907 for consistency with other handlers. Do not check whether
1908 cpu_log is a hash-table if garbage collecting, since it
1909 doesn't matter in that case.
1910 (deliver_profiler_signal): Rename from sigprof_handler,
1911 for consistency with other handlers.
1912 (setup_cpu_timer): New function, with much of what used to be in
1913 Fprofiler_cpu_start. Check for out-of-range argument.
1914 Prefer timer_settime if available, and prefer
1915 thread cputime clocks, then process cputime clocks, then
1916 monotonic clocks, to the old realtime clock. Use make_timeval
1917 to round more-correctly when falling back to setitimer.
1918 (Fprofiler_cpu_start): Use it.
1919 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1920 Don't assume that passing NULL as the 2nd argument of setitimer
1921 is the same as passing a pointer to all-zero storage.
1922 Ignore SIGPROF afterwards.
1923 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1924 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1925 non-fatal signal handlers. Ignore SIGPROF on startup.
1926 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1927 in profiler.c, since sysdep.c now uses it.
1929 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1930 Suggested by Eli Zaretskii in
1931 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1944 (Fbacktrace_frame): Adjust accordingly.
1946 2012-09-28 Glenn Morris <rgm@gnu.org>
1948 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
1949 (Frun_hook_with_args_until_failure): Doc fixes.
1951 2012-09-28 Eli Zaretskii <eliz@gnu.org>
1953 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
1954 Qautomatic_redisplay and change the symbol name. All users changed.
1956 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
1958 * profiler.c (sigprof_handler): Fix race condition.

1967 * Makefile.in (LIB_TIMER_TIME): New macro.
1969 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
1970 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to

1981 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
1983 * character.h (MAYBE_UNIFY_CHAR): Remove.
1984 * charset.c, charset.h (maybe_unify_char): Now static.
1985 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1986 Since this stuff is now private to charset.c, there's no need for
1987 a public macro and no need to inline by hand.
1989 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
1990 Stefan Monnier <monnier@iro.umontreal.ca>
1991 Juanma Barranquero <lekktu@gmail.com>

2016 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
2018 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
2020 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
2022 Prefer POSIX timers if available.
2023 They avoid a race if the timer is too close to the current time.
2024 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
2025 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
2026 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
2028 2012-09-25 Eli Zaretskii <eliz@gnu.org>
2030 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
2031 CHAR_STRING_ADVANCE.
2032 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
2033 STRING_CHAR_ADVANCE.
2035 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
2037 Move Vlibrary_cache to emacs.c and reset before dumping.

2049 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
2051 * w32.h (Vlibrary_cache): Do not declare.
2053 2012-09-25 Eli Zaretskii <eliz@gnu.org>
2055 * w32proc.c (sys_signal): Handle all signals defined by the
2056 MS-Windows runtime, not just SIGCHLD. Actually install the signal
2057 handlers for signals supported by Windows. Don't override
2058 term_ntproc as the handler for SIGABRT.
2059 (sigaction): Rewrite to call sys_signal instead of duplicating its
2061 (sys_kill): Improve commentary.
2063 * w32.c (term_ntproc): Accept (and ignore) one argument, for
2064 consistency with a signature of a signal handler. All callers
2066 (init_ntproc): Accept an argument DUMPING. If dumping, don't
2067 install term_ntproc as a signal handler for SIGABRT, as that
2068 should be done by the dumped Emacs.
2070 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
2072 * w32select.c (term_w32select): Protect against repeated
2073 invocation by setting clipboard_owner to NULL after calling
2076 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
2077 and term_ntproc to their modified signatures.
2079 * character.c (char_string, string_char): Remove calls to
2080 MAYBE_UNIFY_CHAR. See the discussion starting at

2084 2012-09-25 Chong Yidong <cyd@gnu.org>
2086 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
2088 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
2090 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
2091 when encountering an unknown bytecode.
2093 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
2095 image.c, indent.c: Use bool for booleans.
2096 * dispextern.h (struct image_type): Members valid_p, load, init
2097 now return bool, not int. All uses changed.
2098 * image.c: Omit unnecessary static decls.
2099 (x_create_bitmap_mask, x_build_heuristic_mask):
2100 Return void, not int, since callers don't care about the return value.

2135 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2137 Move pid_t related decls out of lisp.h.
2138 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
2139 (interruptible_wait_for_termination):
2140 Move these decls from lisp.h to syswait.h, since they use pid_t.
2141 Needed on FreeBSD; see Herbert J. Skuhra in
2142 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
2143 * callproc.c: Include syswait.h.

2189 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2191 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2192 fatal_error_backtrace.
2194 * w32proc.c (sys_kill): Undo last change: don't do anything when
2195 invoked to deliver SIGABRT to our own process. This is now
2196 handled by emacs_raise.
2198 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2200 * w32term.c (w32_read_socket): Remove leftover reference to
2201 interrupt_input_pending.
2203 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2205 Do not use SA_NODEFER.
2206 Problem reported by Dani Moncayo in
2207 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2209 * sysdep.c (emacs_abort): Do not reset signal handler.
2210 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2211 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2212 wanted even on POSIXish hosts, and it doesn't work on Windows.
2214 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2216 * xterm.c (x_term_init): Call fixup_locale before and after calling
2217 gtk_init (Bug#12392).
2219 2012-09-23 Chong Yidong <cyd@gnu.org>
2221 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2222 Vdynamic_library_alist.
2224 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2225 (Fgnutls_available_p): Caller changed.
2227 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2228 (Flibxml_parse_xml_region): Likewise.
2230 * dispextern.h (struct image_type): Remove arg from init function.
2232 * image.c (Finit_image_library, lookup_image_type)
2233 (define_image_type): Remove now-unneeded second arg.
2234 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2235 (init_tiff_functions, init_gif_functions, init_svg_functions):
2236 Arglist and w32_delayed_load calling convention changed.
2237 (gs_type): Remove init_gs_functions; there is no such function.
2238 (valid_image_p, make_image): Fix caller to lookup_image_type.
2240 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2242 Simplify and avoid signal-handling races (Bug#12471).
2244 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2245 Avoid recursive loop if there's a fatal error in the function itself.
2246 * atimer.c (pending_atimers):
2247 * blockinput.h: Don't include "atimer.h"; no longer needed.
2248 (interrupt_input_pending): Remove. All uses removed.
2249 pending_signals now counts both atimers and ordinary interrupts.
2250 This is less racy than having three separate pending-signal flags.
2251 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2253 Rename from their upper-case counterparts BLOCK_INPUT,
2254 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2255 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2256 This makes it easier to access volatile variables more accurately.
2257 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2258 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2259 that's more reliable if the code is buggy and sets
2260 interrupt_input_blocked to a negative value. All uses changed.
2261 * atimer.c (deliver_alarm_signal):
2262 Remove. No need to deliver this to the parent; any thread can
2263 handle this signal now. All uses replaced by underlying handler.
2264 * atimer.c (turn_on_atimers):
2265 * dispnew.c (handle_window_change_signal):
2266 * emacs.c (handle_danger_signal):
2267 * keyboard.c (kbd_buffer_get_event):
2268 Don't reestablish signal handler; not needed with sigaction.
2269 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2271 Rework to avoid unnecessary accesses to volatile variables.
2272 (UNBLOCK_INPUT_TO): Now a function.
2273 (totally_unblock_input, unblock_input): New decls.
2274 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2275 (init_data): Remove. Necessary stuff now done in init_signal.
2276 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2277 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2278 (fatal_error_code): Remove; no longer needed.
2279 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2280 it doesn't always backtrace. All uses changed. No need to reset
2281 signal to default, since sigaction and/or die does that for us now.
2282 Use emacs_raise (FOO), not kill (getpid (), FOO).
2283 (main): Check more-accurately whether we're dumping.
2284 Move fatal-error setup to sysdep.c
2285 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2286 * gtkutil.c (xg_get_file_name, xg_get_font):
2287 Remove no-longer-needed signal-mask manipulation.
2288 * keyboard.c, process.c (POLL_FOR_INPUT):
2289 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2290 * keyboard.c (read_avail_input): Remove.
2291 All uses replaced by gobble_input.
2292 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2293 (kbd_buffer_store_event_hold, gobble_input):
2294 (record_asynch_buffer_change) [USABLE_SIGIO]:
2295 (store_user_signal_events):
2296 No need to mess with signal mask.
2297 (gobble_input): If blocking input and there are terminals, simply
2298 set pending_signals to 1 and return. All hooks changed to not
2299 worry about whether input is blocked.
2300 (process_pending_signals): Clear pending_signals before processing
2301 them, in case a signal comes in while we're processing.
2302 By convention callers now test pending_signals before calling us.
2303 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2304 New functions, to support changes to blockinput.h.
2305 (handle_input_available_signal): Now extern.
2306 (reinvoke_input_signal): Remove. All uses replaced by
2308 (quit_count): Now volatile, since a signal handler uses it.
2309 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2310 All callers changed. Block SIGINT only if not already blocked.
2311 Clear sigmask reliably, even if Fsignal returns, which it can.
2312 Omit unnecessary accesses to volatile var.
2313 (quit_throw_to_read_char): No need to restore sigmask.
2314 * keyboard.c (gobble_input, handle_user_signal):
2315 * process.c (wait_reading_process_output):
2316 Call signal-handling code rather than killing ourselves.
2317 * lisp.h: Include <float.h>, for...
2318 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2319 (pending_signals): Now volatile.
2320 (syms_of_data): Now const if IEEE floating point.
2321 (handle_input_available_signal) [USABLE_SIGIO]:
2322 (terminate_due_to_signal, record_child_status_change): New decls.
2323 * process.c (create_process): Avoid disaster if memory is exhausted
2324 while we're processing a vfork, by tightening the critical section
2326 (send_process_frame, process_sent_to, handle_pipe_signal)
2327 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2329 (send_process): No need for setjmp/longjmp any more, since the
2330 SIGPIPE stuff is now gone. Instead, report an error if errno
2332 (record_child_status_change): Now extern. PID and W are now args.
2333 Return void, not bool. All callers changed.
2334 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2335 Remove. All uses removed. This bug should be fixed now in a
2337 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2338 and record the child status change directly. This avoids the
2339 need to futz with the signal mask.
2340 (process_fatal_action): Move here from emacs.c.
2341 (emacs_sigaction_flags): New function, containing
2342 much of what used to be in emacs_sigaction_init.
2343 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2344 caught by emacs, to make races less likely.
2345 (deliver_process_signal): Rename from handle_on_main_thread.
2347 (BACKTRACE_LIMIT_MAX): Now at top level.
2348 (thread_backtrace_buffer, threadback_backtrace_pointers):
2350 (deliver_thread_signal, deliver_fatal_thread_signal):
2351 New functions, for more-accurate delivery of thread-specific signals.
2352 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2353 (deliver_arith_signal): Handle in this thread, not
2354 in the main thread, since it's triggered by this thread.
2355 (maybe_fatal_sig): New function.
2356 (init_signals): New arg DUMPING so that we can be more accurate
2357 about whether we're dumping. Caller changed.
2358 Treat thread-specific signals differently from process-general signals.
2359 Block all signals while handling fatal error; that's safer.
2360 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2362 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2363 Ignore SIGPIPE unless batch.
2364 (emacs_backtrace): Output backtrace for the appropriate thread,
2365 which is not necessarily the main thread.
2366 * syssignal.h: Include <stdbool.h>.
2367 (emacs_raise): New macro.
2368 * xterm.c (x_connection_signal): Remove; no longer needed
2369 now that we use sigaction.
2370 (x_connection_closed): No need to mess with sigmask now.
2371 (x_initialize): No need to reset SIGPIPE handler here, since
2372 init_signals does this for us now.
2374 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2376 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2377 background rect may be larger (Bug#12245).
2379 2012-09-23 Chong Yidong <cyd@gnu.org>
2381 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2383 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2385 * .gdbinit: Just stop at fatal_error_backtrace.
2386 See Stefan Monnier's request in
2387 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2388 Remove no-longer-used query of system type.
2390 2012-09-22 Chong Yidong <cyd@gnu.org>
2392 * search.c (Freplace_match): Doc fix (Bug#12325).
2394 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2396 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2397 (Fline_end_position): Doc fix.
2399 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2401 2012-09-22 Chong Yidong <cyd@gnu.org>
2403 * dispextern.h (struct image_type): Add new slot, storing a type
2404 initialization function.
2406 * image.c (define_image_type): Call the image initializer function
2407 if it is defined. Arguments and return value changed.
2408 (valid_image_p, make_image): Callers changed.
2409 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2410 (gif_type, imagemagick_type, svg_type, gs_type):
2411 Add initialization functions.
2412 (Finit_image_library): Call lookup_image_type.
2413 (CHECK_LIB_AVAILABLE): Macro deleted.
2414 (lookup_image_type): Call define_image_type here, rather than via
2415 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2416 (syms_of_image): Move define_image_type calls for xbm_type and
2417 pbm_type to lookup_image_type.
2419 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2421 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2422 'idle_timers' from here ...
2423 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2424 lists, to avoid infloops when the timer does something stupid,
2425 like reinvoke itself with the same or smaller time-out.
2428 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2430 * window.c (Fsplit_window_internal): Handle only Qt value of
2431 Vwindow_combination_limit separately.
2432 (Qtemp_buffer_resize): New symbol.
2433 (Vwindow_combination_limit): New default value.
2436 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2438 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2439 the new overlay string. (Bug#10159)
2441 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2443 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2444 or that fprintf is async-signal-safe. POSIX doesn't require
2447 2012-09-22 Chong Yidong <cyd@gnu.org>
2449 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2452 2012-09-22 Kenichi Handa <handa@gnu.org>
2454 * composite.c (composition_reseat_it): Handle the case that a
2455 grapheme cluster is not covered by a single font (Bug#12352).
2457 2012-09-21 Chong Yidong <cyd@gnu.org>
2459 * image.c (define_image_type): Avoid adding duplicate types to
2460 image_types (Bug#12463). Suggested by Jörg Walter.
2462 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2464 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2465 (print_load_command_name): Add case LC_DATA_IN_CODE.
2466 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2468 2012-09-21 Glenn Morris <rgm@gnu.org>
2470 * eval.c (Frun_hook_with_args_until_success)
2471 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2473 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2475 * fileio.c (Ffile_selinux_context): Only call freecon when
2476 lgetfilecon succeeded.
2477 (Fset_file_selinux_context): Likewise. (Bug#12444)
2479 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2481 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2482 reordering, locate the cursor by calling set_cursor_from_row; if
2483 that fails, clear the desired glyph matrix before returning a
2484 failure indication to the caller. Fixes leaving garbled display
2485 when fast scrolling with a down-key. (Bug#12403)
2486 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2487 scrolling through multibyte text.
2489 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2491 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2492 calling mark_vectorlike since that's the one that marks the window.
2493 (mark_discard_killed_buffers): Mark the final cdr.
2494 * window.h (struct window): Move prev/next_buffers to the
2495 non-standard fields.
2496 * window.c (make_window): Initialize prev/next_buffers manually.
2498 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2500 Omit unused arg EXPECTED from socket hooks.
2501 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2502 * nsterm.m (ns_term_init):
2503 * termhooks.h (struct terminal.read_socket_hook):
2504 * w32inevt.c (w32_console_read_socket):
2505 * w32term.c (w32_read_socket):
2506 * xterm.c (XTread_socket):
2507 Omit unused arg EXPECTED. All callers changed.
2508 (store_user_signal_events): Return void, not int, since callers no
2509 longer care about the return value. All uses changed.
2511 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2513 * w32gui.h (XParseGeometry): Do not declare.
2515 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2517 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2518 Ignore 'expected'. See Eli Zaretskii in
2519 <http://bugs.gnu.org/12471#8> (last line).
2521 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2522 (XParseGeometry): Now static. Substitute extremal values for
2523 values that are out of range.
2525 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2527 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2529 * nsfns.m (XParseGeometry): Remove.
2530 (Fx_create_frame): Call x_set_offset to correctly interpret
2531 top_pos in geometry.
2533 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2534 (Fx_parse_geometry): If there is a space in string, call
2535 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2537 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2539 * search.c (scan_buffer): Use character positions in calls to
2540 region_cache_forward and region_cache_backward, not byte
2541 positions. (Bug#12196)
2543 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2544 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2546 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2547 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2548 emacs_blocked_malloc, now deleted.
2550 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2552 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2553 The workaround was for improving performance on Solaris 2.4, but
2554 is getting in the way now. Emacs will still work if someone is
2555 still running Solaris 2.4 in a museum somewhere; Sun dropped
2556 support for Solaris 2.4 in 2003.
2557 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2558 * process.c (create_process) [HAVE_WORKING_VFORK]:
2559 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2560 since Emacs no longer uses vfork on that platform.
2562 2012-09-17 Glenn Morris <rgm@gnu.org>
2564 * emacs.c: Use COPYRIGHT.
2566 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2568 Remove configure's --without-sync-input option (Bug#12450).
2569 When auditing signal-handling in preparation for cleaning it up,
2570 I found that SYNC_INPUT has race conditions and would be a real
2571 pain to fix. Since it's an undocumented and deprecated
2572 configure-time option, now seems like a good time to remove it.
2573 Also see <http://bugs.gnu.org/11080#16>.
2574 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2575 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2576 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2577 (malloc_hysteresis):
2578 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2579 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2580 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2581 (dont_register_blocks, bytes_used_when_reconsidered)
2582 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2583 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2584 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2585 Remove. All uses removed.
2586 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2587 implementation, one that depends on whether the new macro
2588 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2590 * atimer.c (run_timers, handle_alarm_signal):
2591 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2592 (handle_async_input, process_pending_signals)
2593 (handle_input_available_signal, init_keyboard):
2594 * nsterm.m (ns_read_socket):
2595 * process.c (wait_reading_process_output):
2596 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2597 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2599 * xterm.c (XTread_socket):
2601 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2602 * eval.c (handling_signal): Remove. All uses removed.
2603 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2604 All uses replaced with the SYNC_INPUT version.
2605 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2607 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2610 * font.c (Ffont_shape_gstring): Remove unused local.
2612 2012-09-16 Glenn Morris <rgm@gnu.org>
2614 * Makefile.in (clean): No longer run nextstep's clean.
2616 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2618 (ns-app): Move here from ns.mk, and simplify.
2619 (clean): Simplify nextstep entry.
2620 * ns.mk: Remove file.
2622 2012-09-17 Kenichi Handa <handa@gnu.org>
2624 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2625 not covert the last few charactes.
2627 2012-09-16 Kenichi Handa <handa@gnu.org>
2629 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2630 here, but just check the validity of glyphs in the glyph-string.
2632 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2634 * window.c (Fwindow_parameter, Fset_window_parameter):
2635 Accept any window as argument (Bug#12452).
2637 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2639 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2640 to ns_term_init to avoid memory leak.
2642 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2643 explicit retain/release.
2644 (ns_term_init): Only allow one display. Initialize outerpool and
2647 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2649 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2650 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2651 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2652 the Microsoft problem in a different way, by altering ../nt/config.nt.
2654 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2669 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2670 by lisp.h. This completes removal of setjmp.h inclusion
2671 erroneously announced in the previous commit. (Bug#12446)
2673 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2676 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2677 not defined as a macro. The latter happens on MS-Windows.
2680 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2682 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2683 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2684 Some instances of '#include <setjmp.h>' removed, if the
2685 only reason for the instance was because "lisp.h" was included.
2686 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2687 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2688 and _longjmp with the new symbols. Emacs already uses _setjmp if
2689 available, so this change affects only POSIXish hosts that have
2690 sigsetjmp but not _setjmp, such as some versions of Solaris and
2691 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2692 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2693 (png_load_body) [HAVE_PNG]:
2694 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2695 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2696 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2697 since PNG requires jmp_buf. This is the only exception to the
2698 general rule that we now use sys_setjmp and sys_longjmp.
2699 This exception is OK since this code does not change the signal
2700 mask or longjmp out of a signal handler.
2702 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2704 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2705 Include "syssignal.h", for 'main_thread'.
2707 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2709 Avoid out-of-range marker position (Bug#12426).
2710 * insdel.c (replace_range, replace_range_2):
2711 Adjust markers before overlays, as suggested by comments.
2712 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2713 Remove redundant check before calling offset_intervals.
2715 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2717 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2718 current buffer (Bug#12387).
2720 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2722 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2724 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2726 Use a more backwards-compatible timer format (Bug#12430).
2727 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2728 vector element, not from the 4th, since PSECS is now at the end.
2729 (Fcurrent_idle_time): Doc fix.
2731 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2733 Function to mark objects and remove killed buffers at once.
2734 * alloc.c (discard_killed_buffers): Rename to ...
2735 (mark_discard_killed buffers) ... new name. Add marking
2736 of remaining objects. Fix comment. Adjust users.
2737 (mark_object): Do not touch frame buffer lists here.
2738 * frame.c (delete_frame): Reset frame buffer lists here.
2740 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2742 Better workaround for GNOME bug when --enable-gcc-warnings.
2743 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2744 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2745 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2747 Simplify SIGIO usage (Bug#12408).
2748 The code that dealt with SIGIO was crufty and confusing, e.g., it
2749 played tricks like "#undef SIGIO" but these tricks were not used
2750 consistently. Simplify mostly by not #undeffing standard symbols,
2751 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2752 or not as we please) rather than "defined SIGIO" (standard symbol
2753 that we probably shouldn't #undef).
2754 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2755 Modules that need it can include it.
2756 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2757 * dispextern.h (ignore_sigio): New decl.
2758 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2759 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2760 * emacs.c (shut_down_emacs):
2761 * keyboard.c (kbd_buffer_store_event_hold):
2762 Use ignore_sigio rather than invoking 'signal' directly.
2763 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2765 (FIONREAD, SIGIO): Do not #undef.
2766 (tty_read_avail_input): Use #error rather than a syntax error.
2767 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2768 for I_PIPE, used by SETUP_SLAVE_PTY.
2769 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2770 * sysdep.c (croak): Remove; no longer needed. This bit of
2771 temporary code, with Fred N. Fish's comment that it's temporary,
2772 has been in Emacs since at least 1992!
2773 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2774 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2775 * syssignal.h (croak): Remove decl.
2776 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2777 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2778 now that we're termios-only.
2779 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2780 * term.c (dissociate_if_controlling_tty): Use #error rather than
2783 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2784 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2785 to work around GNOME bug 683906.
2786 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2787 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2788 This works around GCC bug 54561.
2790 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2792 More fixes for 'volatile' and setjmp/longjmp.
2793 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2794 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2795 (png_load_body) [HAVE_PNG]:
2796 (jpeg_load_body) [HAVE_JPEG]:
2797 New function, with most of the old parent function's body.
2798 (png_load) [HAVE_PNG]:
2799 (jpeg_load) [HAVE_JPEG]:
2800 Invoke the new function, to avoid longjmp munging our locals.
2801 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2802 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2803 longjmp is passed 2, as the C standard doesn't guarantee this.
2804 Instead, store the failure code into mgr->failure_code.
2806 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2808 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2809 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2810 (syms_of_keyboard): Remove support for unread-command-char.
2812 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2814 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2815 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2816 violation. (Bug#12426)
2818 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2820 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2822 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2824 * eval.c: Add `inhibit-debugger'.
2825 (Qinhibit_debugger): New symbol.
2826 (call_debugger): Bind it instead of Qdebug_on_error.
2827 (maybe_call_debugger): Test Vinhibit_debugger.
2828 (syms_of_eval): Define inhibit-debugger.
2829 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2830 (syms_of_xdisp): Remove inhibit-debug-on-message.
2832 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2834 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2835 If a nonvolatile local variable is written before a _longjmp to
2836 the frame containing the variable, and is read after the _longjmp,
2837 the value read is indeterminate. Some local variables of type
2838 'struct handler' and 'struct catchtag' are used in this way, so
2839 mark each of their slots as volatile if the slot can be set before
2840 _longjmp and read afterwards.
2841 * lisp.h (struct handler): var and chosen_clause are now volatile.
2842 (struct catchtag): val, next, and pdlcount are now volatile.
2844 * bidi.c (bidi_push_it, bidi_pop_it):
2845 * fns.c (copy_hash_table):
2846 * image.c (define_image_type):
2847 * keyboard.c (kbd_buffer_store_event_hold):
2848 * process.c (Fprocess_send_eof):
2849 * xfaces.c (x_create_gc) [HAVE_NS]:
2850 * xgselect.c (xg_select):
2851 Prefer assignment to memcpy when either will do.
2853 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2854 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2855 time an item is removed. No need to mark this function 'inline';
2856 the compiler knows better than we do.
2858 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2860 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2861 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2862 to change_frame_size (Bug#12388).
2863 (windowDidResize:): Pass YES to updateFrameSize.
2865 * nsterm.h: Add delay parameter to updateFrameSize.
2867 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2869 Discard killed buffers from deleted window and frame objects.
2870 This reduces an amount of references to killed buffers and
2871 helps GC to reclaim them faster.
2872 * alloc.c (discard_killed_buffers): New function.
2873 (mark_object): Use it for deleted windows and frames.
2874 (mark_object): If symbol's value is set up for a killed buffer
2875 or deleted frame, restore its global binding.
2876 * data.c (swap_in_global_binding): Add GC notice.
2877 (swap_in_symval_forwarding): Use convenient set_blv_where.
2878 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2879 * window.h: ... to here.
2881 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2883 Convenient macro to check whether the buffer is live.
2884 * buffer.h (BUFFER_LIVE_P): New macro.
2885 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2886 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2888 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2890 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2891 composition cases (Bug#12364).
2893 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2894 overhang of succeeding glyphs overlapping box cursor.
2896 * w32term.c (x_draw_glyph_string): Likewise.
2898 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2900 Simplify, document, and port floating-point (Bug#12381).
2901 The porting part of this patch fixes bugs on non-IEEE platforms
2902 with frexp, ldexp, logb.
2903 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2905 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2906 support, by removing commented-out code and briefly listing the
2907 C89 functions excluded. The commented-out stuff was confusing
2908 maintenance, e.g., we thought we needed cbrt but it was commented out.
2909 (logb): Remove decl; no longer needed.
2910 (isfinite): New macro, if not already supplied.
2911 (isnan): Don't replace any existing macro.
2912 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2913 are present on all C89 platforms.
2914 (Ffrexp): Do not special-case zero, as frexp does the right thing
2916 (Flogb): Do not use logb, as it doesn't have the desired meaning
2917 on hosts that use non-base-2 floating point. Instead, stick with
2918 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2919 frexp, to avoid getting an unspecified result.
2921 * xdisp.c (Qinhibit_debug_on_message): Now static.
2923 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2925 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2926 NSBezierPath (Bug#12131).
2928 2012-09-10 Chong Yidong <cyd@gnu.org>
2930 * fns.c (Fdelq, Fdelete): Doc fix.
2932 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2934 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2935 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2937 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2939 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2940 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2943 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2945 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2946 left fringe if the window has a left margin. This avoids leaving
2947 traces of the cursor because its leftmost pixel is not drawn over.
2949 * dispnew.c (update_window_line): When the left margin area of a
2950 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2951 that screen line. (Bug#12277)
2953 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2955 Assume C89 or later for math functions (Bug#12381).
2956 This simplifies the code, and makes it a bit smaller and faster,
2957 and (most important) makes it easier to clean up signal handling
2958 since we can stop worring about floating-point exceptions in
2959 library code. That was a problem before C89, but the problem
2960 went away many years ago on all practical Emacs targets.
2961 * data.c, image.c, lread.c, print.c:
2962 Don't include <math.h>; no longer needed.
2963 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2964 might be autoconfigured, as that never happens.
2966 * doprnt.c (DBL_MAX_10_EXP):
2967 * print.c (DBL_DIG):
2968 Remove. C89 or later always defines these.
2969 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2970 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2971 (arith_error, domain_error, domain_error2):
2972 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2973 no longer needed -- we simply return what C returns. All uses removed.
2974 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2976 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2977 Remove. All uses expanded, as these macros are no longer used
2978 more than once and are now more trouble than they're worth.
2979 (Ftan): Use tan, not sin / cos.
2980 (Flogb): Assume C89 frexp.
2981 (fmod_float): Assume C89 fmod.
2982 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2983 (init_floatfns): Remove. All uses removed.
2985 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2987 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2988 compositeToPoint for OSX < 10.6 (Bug#12390).
2990 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2992 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2993 This produces more-accurate results.
2995 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2997 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2998 changes (Bug#12088).
3000 2012-09-08 Chong Yidong <cyd@gnu.org>
3002 * syntax.c (Fstring_to_syntax): Doc fix.
3004 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3006 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3007 in the internal border.
3008 (x_set_window_size): Remove static variables and their usage.
3009 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3010 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3011 Remove fringe/internal border adjustment (Bug#11052).
3012 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3013 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3014 (ns_fix_rect_ibw): Remove.
3015 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3016 (ns_dumpglyphs_box_or_relief): Ditto.
3017 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3019 (ns_dumpglyphs_image): Ditto.
3020 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3022 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3023 their usage. Add fringe_extended_p and its use as in other terms.
3024 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3025 scroll bar was removed.
3026 (updateFrameSize): New function.
3027 (windowDidResize): Move code to updateFrameSize and call it.
3029 * nsterm.h (EmacsView): Add updateFrameSize.
3031 2012-09-07 Chong Yidong <cyd@gnu.org>
3033 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3035 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3037 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3039 More signal-handler cleanup (Bug#12327).
3040 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3041 Problem introduced when merging patches. Noted by Eli Zaretskii in
3042 <http://bugs.gnu.org/12327#67>.
3043 * floatfns.c: Comment fix.
3044 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3045 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3046 and anyway the declaration is harmless even if SIGDANGER is not defined.
3047 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3048 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3049 source files not surprisingly expected syssignal.h to define, or
3050 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3051 Include <sys/ioctl.h>, for FIONREAD.
3052 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3053 This eliminates a problem whereby other files mysteriously had
3054 to include "syssignal.h" before including "systty.h" if they
3055 wanted to use "#ifdef SIGIO".
3057 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3059 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3061 * w32.c (sigemptyset): Empty the set.
3062 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3064 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3066 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3068 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3069 (mark_object): Likewise for frame objects.
3071 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3073 * syssignal.h (handle_on_main_thread): Always declare,
3074 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3075 This ports to platforms without HAVE_PTHREAD.
3077 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3079 Signal-handler cleanup (Bug#12327).
3080 Emacs's signal handlers were written in the old 4.2BSD style with
3081 sigblock and sigmask and so forth, and this led to some
3082 inefficiencies and confusion. Rewrite these to use
3083 pthread_sigmask etc. without copying signal sets around. Also,
3084 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3085 'signal', and instead use functions that do not attempt to take
3086 over the system name space. This patch causes Emacs's text
3087 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3088 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3089 Do not include <signal.h> or "syssignal.h", as these
3090 modules do not use signals.
3091 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3092 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3093 Do not include <signal.h>, as "syssignal.h" does that for us now.
3094 * atimer.c (sigmask_atimers): New function.
3095 (block_atimers, unblock_atimers): New functions,
3096 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3098 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3099 no longer needed here.
3100 * emacs.c (main): Inspect existing signal handler with sigaction,
3101 so that there's no need to block and unblock SIGHUP.
3102 * sysdep.c (struct save_signal): New member 'action', replacing
3103 old member 'handler'.
3104 (save_signal_handlers, restore_signal_handlers):
3105 Use sigaction instead of 'signal' to save and restore.
3106 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3107 New function. All users of 'signal' modified to use set_sighandler
3108 if they're writeonly, and to use sys_signal if they're read+write.
3109 (emacs_sigaction_init, forwarded_signal): New functions.
3110 (sys_signal): Remove. All uses replaced by calls to sigaction
3111 and emacs_sigaction_init, or by direct calls to 'signal'.
3112 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3113 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3114 all uses replaced by pthread_sigmask etc. calls.
3115 * syssignal.h: Include <signal.h>.
3116 (emacs_sigaction_init, forwarded_signal): New decls.
3117 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3118 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3119 (sigmask, sys_sigmask): Remove; no longer needed.
3120 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3121 (sigblock, sigunblock, sigfree):
3122 (sigsetmask) [!defined sigsetmask]:
3123 Remove. All uses replaced by pthread_sigmask.
3124 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3125 no longer need to be replaced, and its typical old uses
3126 are now done via emacs_sigaction_init and sigaction.
3127 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3128 (sys_sigdel): Remove; unused.
3129 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3131 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3133 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3134 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3136 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3138 Explicitly mark buffer_defaults and buffer_local_symbols.
3139 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3140 mark_local_symbols here.
3141 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3142 since special buffers aren't marked here any more.
3143 (allocate_buffer): Chain new buffer with all_buffers here...
3144 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3146 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3147 (syms_of_buffer): Remove staticpro of the above.
3148 (init_buffer_once): Set names for buffer_defaults and
3149 buffer_local_symbols.
3151 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3153 Use bool for booleans in font-related modules.
3154 * font.c (font_intern_prop, font_style_to_value)
3155 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3156 (generate_otf_features, font_check_otf_features, font_check_otf)
3157 (font_match_p, font_list_entities, font_at):
3158 * fontset.c (fontset_id_valid_p, reorder_font_vector
3159 (fontset_find_font, Fset_fontset_font)
3160 (face_suitable_for_char_p) [0]:
3161 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3162 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3163 (m17n_flt_initialized, ftfont_shape_by_flt):
3164 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3165 * nsfont.m (nsfont_draw):
3166 * w32font.c (w32font_draw):
3167 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3168 Use bool for booleans.
3169 * font.h: Adjust to above API changes.
3170 (struct font, struct font_driver, struct font_driver_list):
3171 Use bool for booleans.
3172 (struct font): Remove useless member encoding_type.
3174 * fontset.c, xftfont.c: Omit unnecessary static decls.
3176 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3178 * alloc.c (mark_object): Revert window marking code
3179 since it's unsafe for the Fset_window_configuration.
3181 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3183 Fix race conditions with signal handlers and errno (Bug#12327).
3184 Be more systematic about preserving errno whenever a signal
3185 handler returns, even if it's not in the main thread. Do this by
3186 renaming signal handlers to distinguish between signal delivery
3187 and signal handling. All uses changed.
3188 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3189 * data.c (deliver_arith_signal): Rename from arith_error.
3190 * dispnew.c (deliver_window_change_signal): Rename from
3191 window_change_signal.
3192 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3193 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3194 * keyboard.c (deliver_input_available_signal): Rename from
3195 input_available_signal.
3196 (deliver_user_signal): Rename from handle_user_signal.
3197 (deliver_interrupt_signal): Rename from interrupt_signal.
3198 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3199 (deliver_child_signal): Rename from sigchld_handler.
3200 * atimer.c (handle_alarm_signal):
3201 * data.c (handle_arith_signal):
3202 * dispnew.c (handle_window_change_signal):
3203 * emacs.c (handle_fatal_signal, handle_danger_signal):
3204 * keyboard.c (handle_input_available_signal):
3205 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3206 * process.c (handle_pipe_signal, handle_child_signal):
3207 New functions, with the actual signal-handling code taken from the
3208 original respective signal handlers, sans the sporadic attempts to
3209 preserve errno, since that's now done by handle_on_main_thread.
3210 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3211 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3212 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3214 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3215 Move initialization of main_thread to sysdep.c's init_signals.
3216 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3217 our usage, and simplifies the mainline code.
3218 (record_child_status_change): New static function, as a helper
3219 for handle_child_signal, and with most of the old child handler's
3221 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3222 (handle_child_signal): Use the above.
3223 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3224 Moved here from emacs.c.
3225 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3226 code moved here from emacs.c's main function.
3227 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3228 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3229 This lets callers save and restore errno properly.
3231 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3233 Remove redundant or unused things here and there.
3234 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3235 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3236 * editfns.c (Fcompare_buffer_substrings): Likewise.
3237 * frame.h (struct terminal, struct font_driver_list):
3238 Remove redundant declarations.
3239 * window.h (Qleft, Qright): Likewise.
3241 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3243 Do not mark objects from deleted buffers, windows and frames.
3244 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3245 (mark_object): Likewise for windows and frames.
3247 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3249 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3250 buffer_defaults and buffer_local_symbols as valid objects.
3251 Return special value to denote them.
3253 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3255 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3256 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3257 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3258 (file_name_absolute_p, Fsubstitute_in_file_name):
3259 (check_executable, check_writable, Ffile_accessible_directory_p)
3260 (Fset_file_selinux_context, Fdefault_file_modes)
3261 (Finsert_file_contents, choose_write_coding_system)
3262 (Fwrite_region, build_annotations, a_write, e_write)
3264 * filelock.c (boot_time_initialized, get_boot_time)
3265 (get_boot_time_1, lock_file_1, within_one_second):
3266 * floatfns.c (in_float):
3267 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3268 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3269 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3270 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3271 * window.c (compare_window_configurations):
3272 Use bool for booleans.
3273 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3274 (Fdefault_file_modes): Now mode_t, not int, for modes.
3275 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3276 (internal_delete_file): Now returns void, not a (boolean) int,
3277 since nobody was looking at the return value.
3278 * lisp.h, window.h: Adjust to above API changes.
3280 * xdisp.c (set_message): Simplify and reindent last change.
3282 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3284 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3286 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3288 * eval.c (call_debugger): Make the function non-static so that we
3289 can call it from set_message.
3291 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3292 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3294 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3296 Give more-useful info on a fatal error (Bug#12328).
3297 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3298 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3299 of doing the work ourselves.
3300 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3301 do most of the work.
3302 (fatal_error_backtrace): New function, taken from the guts
3303 of the old fatal_error_signal, but with a new option to output
3305 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3306 info about the signal than just its number.
3307 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3308 * sysdep.c: Include <execinfo.h>
3309 (emacs_backtrace): New function, taken partly from the previous
3310 code of the 'die' function.
3311 (emacs_abort): Call fatal_error_backtrace rather than abort.
3313 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3315 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3316 eager (load-time) macro-expansion.
3317 * lisp.mk (lisp): Add macroexp.
3319 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3321 Simplify redefinition of 'abort' (Bug#12316).
3322 Do not try to redefine the 'abort' function. Instead, redo
3323 the code so that it calls 'emacs_abort' rather than 'abort'.
3324 This removes the need for the NO_ABORT configure-time macro
3325 and makes it easier to change the abort code to do a backtrace.
3326 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3327 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3328 Remove; sysdep.c's emacs_abort now takes its place.
3329 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3330 'abort' changed to use 'emacs_abort'.
3331 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3332 (abort) [!defined abort]: Rename to ...
3333 (emacs_abort): ... new name.
3334 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3335 the place of the old 'abort' in emacs.c.
3336 * w32.c, w32fns.c (abort): Do not #undef.
3337 * w32.c (emacs_abort): Rename from w32_abort.
3339 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3341 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3342 offsets[j].dv, since the y axis of the screen coordinates points
3343 down, while the y axis of the font definition coordinates points
3344 up. This fixes display of Arabic diacritics such as KASRA and
3345 KASRATAN. (Bug#11860)
3347 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3349 Be more systematic about _setjmp vs setjmp.
3350 * alloc.c (test_setjmp, mark_stack):
3351 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3352 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3353 (png_load, my_error_exit, jpeg_load):
3354 * process.c (send_process_trap, send_process):
3355 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3356 The underscored versions are up to 30x faster on some hosts.
3357 Formerly, the code used setjmp+longjmp sometimes and
3358 _setjmp+_longjmp at other times, with no particular reason to
3359 prefer setjmp+longjmp.
3361 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3363 Fix minor problem found by static checking.
3364 * buffer.c (Fdelete_all_overlays): Return nil.
3366 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3368 * buffer.c (Fdelete_all_overlays): New function.
3370 2012-09-03 Chong Yidong <cyd@gnu.org>
3372 * gtkutil.c: Add extern decl for Qxft.
3374 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3376 * emacs.c, eval.c: Use bool for boolean.
3377 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3378 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3379 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

3384 (maybe_call_debugger, Fbacktrace):
3385 * process.c (read_process_output, exec_sentinel):
3386 Use bool for booleans.
3387 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3388 All callers changed.
3389 * eval.c (interactive_p): Omit always-true boolean argument
3390 EXCLUDE_SUBRS_P. All callers changed.
3391 * dispextern.h, lisp.h: Reflect above API changes.
3392 * firstfile.c (dummy): Use the address of 'main', whose signature
3393 won't change, instead of the address of 'initialize', whose
3394 signature just changed from int to bool.
3395 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3396 * msdos.c (fatal_error_in_progress): ... from here.
3397 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3399 (redisplay_internal, unwind_redisplay): Simply clear
3400 REDISPLAYING_P when unwinding, instead of saving its previous,
3401 always-false value and then restoring it.
3403 Clean up some extern decls.
3404 Mostly, this hoists extern decls out of .c files and into .h files.
3405 That way, we're more likely to catch errors if the interfaces change.
3406 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3407 declare xg_mark_data.
3408 * dispextern.h (x_frame_parm_handlers):
3410 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3411 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3412 (Qultra_bold, Qoblique, Qitalic):
3413 Move extern decl here from .c file.
3414 * alloc.c (xg_mark_data) [USE_GTK]:
3416 * eval.c (Qlexical_binding):
3417 * fns.c (time) [!HAVE_UNISTD_H]:

3423 * process.c (QCfamily, QCfilter):
3424 * widget.c (free_frame_faces):
3425 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3426 * xfont.c (x_clear_errors):
3427 * xterm.c (x_frame_parm_handlers):
3428 Remove now-redundant extern decls.
3429 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3430 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3432 * xfaces.c: Remove unnecessary static decls.
3433 * xterm.c (updating_frame): Remove decl of nonexistent object.
3435 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3436 when building globals.h, as the objects that are not built on
3437 this host are not needed to compile C files on this host.
3439 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3441 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

3449 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
3450 (Fsubstitute_command_keys):

3454 (format_time_string, general_insert_function)
3455 (make_buffer_string, make_buffer_string_both)
3456 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
3457 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)
3458 (copy_text, insert_1, insert_1_both, insert_from_string)
3459 (insert_from_string_before_markers, insert_from_string_1)

3468 (set_intervals_multibyte_1, set_intervals_multibyte):
3469 * keyboard.c (decode_timer):
3470 Use bool for boolean.
3471 * intervals.h, lisp.h, systime.h: Reflect above API changes.

3474 2012-09-02 Chong Yidong <cyd@gnu.org>
3476 * keymap.c (push_key_description): Print M-TAB as C-M-i
3479 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3481 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3482 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3487 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3489 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3491 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3492 more than one grapheme cluster passed to the shaper: compute the
3493 offset adjustment values separately for each cluster. (Bug#11860)
3495 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3496 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3497 about implicit conversions from integer to pointer.
3499 2012-09-01 Daniel Colascione <dancol@dancol.org>
3501 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3502 system used too early.
3504 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3506 Better seed support for (random).
3507 * emacs.c (main): Call init_random.
3508 * fns.c (Frandom): Set the seed from a string argument, if given.
3509 Remove long-obsolete Gentzel cruft.

3524 window-system headers.
3526 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

3530 directly accessing frame internals.
3532 * w32font.h: Include font.h. Define syms_of_w32font and
3535 * process.c: Include TERM_HEADER instead of listing all possible
3536 window-system headers.
3538 * nsterm.h: Remove declarations now in frame.h.
3539 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3541 * menu.c: Include TERM_HEADER instead of listing all possible
3542 window-system headers.
3544 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3547 * keyboard.c: Include TERM_HEADER instead of listing all possible
3548 window-system headers.
3550 * image.c: Include TERM_HEADER instead of listing all possible
3551 window-system headers. Declare Vlibrary_cache when compiling for
3554 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3555 window system declarations.
3557 * frame.h: Move common functions here: set_frame_menubar,
3558 x_set_window_size, x_sync, x_get_focus_frame,
3559 x_set_mouse_position, x_set_mouse_pixel_position,
3560 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
3561 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
3562 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,

3581 the current window system; include in list of objects to link into
3584 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3586 Remove mark_ttys function and fix tty_display_info initialization.
3587 * lisp.h (mark_ttys): Remove prototype.
3588 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3589 to mark_ttys because all possible values of 'top_frame' slot are
3590 the frames which are reachable from Vframe_list.
3591 * term.c (mark_ttys): Remove.
3592 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3594 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3596 Change struct frame bitfields from unsigned char to unsigned.
3597 * frame.h (struct frame): Change type of 'display_preempted',
3598 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
3599 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
3600 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3601 bitfields from unsigned char to unsigned.
3603 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3605 Remove unused member of struct x_output and struct w32_output.
3606 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.

3609 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
3611 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
3612 does not become zero (Bug#12234).
3614 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
3616 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3617 for GCC 4.7.1 x86-64.
3619 2012-08-30 Glenn Morris <rgm@gnu.org>
3621 * lread.c (init_lread): For out-of-tree builds, only add the
3622 source directory's site-lisp dir to the load-path if it exists,
3623 consistent with in-tree builds. (Bug#12302)
3625 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3627 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
3628 button_values to NULL. Call setStykeMask so dialogs get a close button.
3629 (windowShouldClose:): Set window_closed.
3630 (dealloc): New member, free button_values.
3631 (process_dialog:): Make member function. Remove window argument,
3632 replace window with self. Count buttons and allocate and store values
3634 (addButton:value:row:): value is int with the name tag. Call setTag
3635 with tag. Remove return self, declare return value as void.
3636 (addString:row:): Remove return self, declare return value as void.
3637 (addSplit): Remove return self, declare return value as void.
3638 (clicked:): Remove return self, declare return value as void.
3639 Set dialog_return to button_values[seltag]. Code formatting change.
3640 (initFromContents:isQuestion:): Adjust call to process_dialog.
3641 Code formatting change.
3642 (timeout_handler:): Set timer_fired to YES.
3643 (runDialogAt:): Set timer_fired to NO.
3644 Handle click on close button as quit.
3646 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3647 Add window_closed and button_values. Add void as return value for
3648 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3649 Add process_dialog as new member.
3651 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3653 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
3654 is not one of the heaps we manage. (Bug#12242)
3656 2012-08-28 Glenn Morris <rgm@gnu.org>
3658 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

3669 * buffer.c (Fset_buffer_major_mode): Signal an error
3670 if the buffer is dead.
3671 (Fother_buffer, other_buffer_safely): Remove redundant
3674 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3676 Always use set_buffer_if_live to restore original buffer at unwind.
3677 * buffer.h (record_unwind_current_buffer): New function.
3678 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:

3680 * undo.c, window.c: Adjust users.
3681 * buffer.c (set_buffer_if_live): Fix comment.
3683 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3685 Fix usage of set_buffer_internal.
3686 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
3687 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
3688 * coding.c (decode_coding): Omit redundant test.

3716 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
3717 and remove last int (actually boolean) argument, which was always 0.
3718 All callers changed.
3719 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
3720 * dispextern.h (struct composition_it): Use bool for boolean.
3721 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
3722 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
3723 * dired.c (file_name_completion):
3724 Use bool for boolean. (This was missed in an earlier change.)
3726 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3728 * window.c (Fset_window_configuration): Revert first part of
3731 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3733 * nsterm.h (NSPanel): New class variable dialog_return.
3735 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
3736 Initialize dialog_return.
3737 (windowShouldClose:): Use stop instead of stopModalWithCode.
3738 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3739 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3741 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

3786 Use bool for booleans.
3787 * coding.h, lisp.h: Reflect above API changes.
3788 * coding.c: Remove unnecessary static function decls.
3789 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3790 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3791 not a boolean 'int', since callers never look at the return value.
3792 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3793 * coding.h (decoding_buffer_size, encoding_buffer_size)
3794 (emacs_mule_string_char): Remove unused extern decls.
3795 (struct iso_2022_spec, struct coding_system):

3797 (struct emacs_mule_spec): Remove unused field 'full_support'.
3798 All initializations removed.
3799 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3801 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3803 Fix spare memory change (Bug#12286).
3804 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3805 (valid_lisp_object_p): Likewise.
3807 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3809 * window.c (Fset_window_configuration): Record any window's old
3810 buffer if it's replaced (see Bug#8789). If the new current
3811 buffer doesn't appear in the selected window, go to its old
3814 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3816 Special MEM_TYPE_SPARE to denote reserved memory.
3817 * alloc.c (enum mem_type): New memory type.
3818 (refill_memory_reserve): Use new type for spare memory.
3819 This prevents live_cons_p and live_string_p from incorrect
3820 detection of uninitialized objects from spare memory as live.
3822 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3825 * Makefile.in (.PHONY): versioclean -> versionclean.
3827 Remove unused external symbols.
3828 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3829 * window.c (Qwindow_valid_p, decode_valid_window):
3830 Now static, not extern.
3831 * data.c (Qinterval): Remove; unused.
3832 (syms_of_data): Do not define 'interval'.
3833 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3834 * window.h (decode_valid_window):
3837 * character.c, charset.c, chartab.c: Use bool for booleans.

3848 (map_sub_char_table):
3849 Use bool for boolean.
3850 * character.c (str_to_unibyte): Omit last boolean argument; it was
3851 always 0. All callers changed.
3852 * character.h, charset.h: Adjust to match previous changes.
3853 * character.h (char_printable_p): Remove decl of nonexistent function.
3854 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3855 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3856 are all boolean, so make them single-bit bitfields.
3858 * lisp.h (ASET): Remove attempt to detect side effects.
3859 It was meant to be temporary and it often doesn't work,
3860 because when IDX has side effects the behavior of IDX==IDX
3861 is undefined. See Stefan Monnier in
3862 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3864 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3866 * lisp.h (functionp): New function (extracted from Ffunctionp).
3867 (FUNCTIONP): Use it.
3868 * eval.c (Ffunctionp): Use it.
3870 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3872 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3873 as that's faster and simpler than static storage. Don't bother
3874 with the g_main_context_query overhead if g_main_context_pending
3875 says no events are pending.
3876 (gfds, gfds_size): Remove these static vars.
3877 (xgselect_initialize): Remove; no longer needed.
3878 All uses and decls removed.
3880 * emacs.c (fatal_error_signal_hook): Remove.
3881 All uses removed. This leftover from old code was always 0.
3883 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3884 * casefiddle.c (casify_object, casify_region):
3885 * casetab.c (set_case_table):
3886 * category.c, category.h (word_boundary_p):
3887 * category.h (CHAR_HAS_CATEGORY):
3888 Use bool for booleans, instead of int.
3890 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3892 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3894 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3896 On assertion failure, print backtrace if available.
3897 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3898 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3899 * Makefile.in (LIB_EXECINFO): New macro.
3902 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3903 * bytecode.c (exec_byte_code):
3904 * callint.c (check_mark, Fcall_interactively):
3905 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3906 (getenv_internal, sync_process_alive, call_process_exited):
3907 * lisp.h (USE_SAFE_ALLOCA):
3908 Use bool for booleans, instead of int.
3909 * lisp.h, process.h: Adjust prototypes to match above changes.
3910 * callint.c (Fcall_interactively): Don't assume the mark's
3911 offset fits in 'int'.
3913 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3915 * buffer.c, buffer.h: Use bool for boolean.
3916 * buffer.c (reset_buffer_local_variables)

3922 (mmap_enlarge, mmap_set_vars):
3923 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3924 Use bool for booleans, instead of int.
3925 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3926 since the 1-or-0 return value is always ignored anyway.
3927 (mmap_initialized_p):
3928 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3929 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3931 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3933 * bidi.c: Use bool for boolean.
3934 This is a bit more readable, and makes the text segment of bidi.o
3935 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3936 Presumably it's faster too.
3937 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3939 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3940 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)

3942 (bidi_explicit_dir_char, bidi_level_of_next_char)
3943 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3944 Use bool for booleans, instead of int.
3945 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3946 (bidi_unshelve_cache): Adjust decls to match code.
3948 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3950 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3953 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3955 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3956 * atimer.h: Include <stdbool.h>.
3958 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3960 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3961 compile time tests instead of run time tests on systems that do
3963 (FRAME_MAC_P): Remove leftover from deleted code.
3964 * frame.c (syms_of_frame): Remove leftover from deleted code.
3966 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3968 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3970 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3972 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3973 Otherwise, the compiler complains about (A?B:C) where B is void
3974 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3975 (fontset_add): Return void, for FONTSET_ADD.
3977 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3979 * alloc.c: Use bool for booleans.
3980 (gc_in_progress, abort_on_gc)
3981 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3982 (dont_register_blocks) [GC_MALLOC_CHECK]:
3983 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

3985 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3986 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3987 (mark_stack, valid_pointer_p, make_pure_string)
3988 (Fgarbage_collect, survives_gc_p, gc_sweep):
3989 Use bool for booleans, instead of int.
3990 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3991 Remove unused local.
3992 * alloc.c (PURE_POINTER_P):
3993 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3994 * editfns.c (Fformat):
3995 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3997 * fns.c (sweep_weak_table):
3998 * lisp.h (suppress_checking, push_message, survives_gc_p)
3999 (make_pure_string, gc_in_progress, abort_on_gc):
4000 * lread.c (readchar, read1):
4001 * print.c (Fprin1_to_string):
4002 * xdisp.c (push_message):
4003 Use bool for booleans affected directly or indirectly by
4006 Make recently-introduced setters macros.
4007 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4008 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4009 (set_fontset_default, set_fontset_fallback): Rename from their
4010 upper-case counterparts, and make them functions rather than macros.
4011 This is more consistent with the other recently-introduced setters.
4012 These don't need to be inline, since they're local.
4014 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4016 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4017 the loop (Bug#12247).
4019 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4021 * lisp.h (vcopy): Use memcpy rather than our own loop.
4022 This fixes a performance regression introduced by the recent
4023 addition of vcopy. This means 'vcopy' will need to be modified
4024 for a copying collector, but that's OK. Also, tighten the
4025 checking in the assertion.
4027 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4029 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4030 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4031 non-base glyph for the width of the base character, according to
4032 what x_draw_composite_glyph_string_foreground expects.
4033 Generate WADJUST value according to composition_gstring_width's
4034 expectations, to produce correct width of the composed character.
4035 Reverse the sign of the DU offset produced by ScriptPlace.
4037 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4039 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4041 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4043 Avoid direct writes to contents member of struct Lisp_Vector.
4044 * lisp.h (vcopy): New function to copy data into vector.
4045 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4046 * fns.c (Ffillarray): Use ASET.
4047 * keyboard.c (timer_check_2): Use AREF and ASET.
4048 (append_tool_bar_item, Frecent_keys): Use vcopy.
4049 * lread.c (read_vector): Use ASET.
4050 * msdos.c (Frecent_doskeys): Use vcopy.
4051 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4052 (Finternal_merge_in_global_face): Use ASET and vcopy.
4053 * xfont.c (xfont_list_pattern): Likewise.
4055 2012-08-21 Martin Rudalics <rudalics@gmx.at>
4057 * window.c (Fwindow_point): For the selected window always return
4058 the position of its buffer's point.
4059 (Fset_window_point): For the selected window always go in its
4060 buffer to the specified position.
4062 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4064 Setter macros for fontsets.
4065 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)

4121 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4123 Rely on <config.h> + <unistd.h> to declare 'environ',
4124 as gnulib does this if the system doesn't.
4125 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4126 Remove declaration. MS-Windows declares it on stdlib.h which is

4160 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4161 Return void, not Lisp_Object. Otherwise, the compiler

4996 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4997 * w32.c (init_environment): Change the default values of many
4998 environment variables in dflt_envvars[] to NULL, to avoid pushing
4999 them into environment when they were not already defined.
5000 Remove the code that deletes site-lisp subdirectories from the default
5001 value of EMACSLOADPATH, as it is no longer needed.
5002 (check_windows_init_file): Now external, not static.
5003 Use Vload_path as is, without adding anything, as this function is now
5004 called when Vload_path is already set up.
5006 * w32.h (check_windows_init_file): Add prototype.
5008 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
5009 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
5010 compatibility with Posix platforms.
5011 (main): Move the call to check_windows_init_file to here from
5013 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
5014 any, in the DEFALT argument into the root of the Emacs build or
5015 installation tree, as appropriate.
5017 * callproc.c (init_callproc_1): Call decode_env_path instead of
5018 doing its equivalent by hand.
5019 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
5020 the code that sets Vexec_path run on MS-Windows.

5032 Now constants, not macros.
5034 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
5036 Remove unnecessary casts involving pointers.
5037 These casts are no longer needed now that we assume C89 or later,
5038 since they involve casting to or from void *.
5039 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
5040 (make_pure_float, make_pure_vector):
5041 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

5050 (x_get_window_property, x_get_window_property_as_lisp_data):
5051 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5052 Remove unnecessary pointer casts.
5053 * alloc.c (record_xmalloc): New function.
5054 * lisp.h (record_xmalloc): New decl.
5055 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5056 more like a function. This is because the pointer cast is not
5057 needed. All uses changed.
5058 * print.c (print_string, print_error_message): Avoid length recalc.
5060 Improve fix for macroexp crash with debugging (Bug#12118).
5061 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5062 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5063 not supposed to be invoked from the garbage collector.
5064 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
5065 (gc_aset): New function, which is like ASET but can be
5066 used in the garbage collector.
5067 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

5080 (map_w32_filename): Improve commentary. Simplify switch.
5081 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
5082 headers (most versions of MinGW w32api don't).
5083 (get_security_info, create_symbolic_link)
5084 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
5086 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
5087 in the argument file name.

5090 (sys_rename): Diagnose renaming of a symlink when the user doesn't
5091 have the required privileges.
5092 (get_file_security_desc_by_name): Rename from
5093 get_file_security_desc.

5095 with addition of handling of symlinks and support for 'lstat'.
5096 If possible, get file's attributes and security information by
5097 handle, not by name. Produce S_IFLNK bit for symlinks, when
5098 called from 'lstat'.
5099 (stat, lstat): New functions, call 'stat_worker'.
5100 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5101 symlinks when the underlying filesystem supports them.
5103 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5105 Fix macroexp crash on Windows with debugging (Bug#12118).
5106 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5107 checking subscripts; problem introduced with the recent
5108 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5109 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5110 since it's used in non-static inline functions now.
5112 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5113 Don't assume buffer size fits in 'int'. Remove unused local.

5131 * character.c (CHARACTER_INLINE):
5132 * charset.c (CHARSET_INLINE):
5133 * composite.c (COMPOSITE_INLINE):
5134 * dispnew.c (DISPEXTERN_INLINE):
5135 * sysdep.c (SYSTIME_INLINE):
5136 Define to EXTERN_INLINE, so that the corresponding functions
5137 are compiled into code.

5139 (INLINE_HEADER_END): New macros.
5140 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5160 hard-coding the path separator.
5162 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5164 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5165 This how ASET and AREF are supposed to work, and makes
5166 it easier to think about future improvements. See
5167 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5168 * charset.h (set_charset_attr): New function.

5422 does that unconditionally. Remove file, which is now empty.
5424 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
5427 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

5442 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
5443 Move to after the definition of struct Lisp_Char_Table,
5444 since the former now needs that type defined.

5545 * w32inevt.c: Include w32inevt.h.
5546 (w32_read_console_input): New inline function, calls either
5547 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
5548 w32_console_unicode_input.
5549 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
5550 (w32_kbd_patch_key, key_event): Use the codepage returned by
5551 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
5552 (key_event): use uChar.UnicodeChar only if
5553 w32_console_unicode_input is non-zero.

5583 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5584 enumeration constants, as PURE and HEAP are too general, and clash
5585 with other headers and sources, such as gmalloc.c and the
5586 MS-Windows system headers. All users changed.
5588 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5590 Revert last save_excursion_save and save_excursion_restore changes.
5591 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5601 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
5603 Improve GDB symbol export (Bug#12036).
5604 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5605 arms of an 'if', not using conditional expressions; otherwise GDB
5606 complains about the types in the unevaluated arm when the argument
5607 is an integer literal.
5608 (xgetint): Simplify expression.
5609 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5610 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5611 Zaretskii in <http://bugs.gnu.org/12036#13>.
5612 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5613 needed now that we have gdb_make_enums_visible.
5614 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5615 (enum enum_USE_LSB_TAG):
5616 New enum types, packaging up enums that need to be exported to GDB.

5635 * xfns.c (syms_of_xfns): Likewise.
5637 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5639 Fast save_excursion_save and save_excursion_restore.
5640 * lisp.h (struct Lisp_Excursion): New data type.
5641 (PVEC_EXCURSION): New pseudovector type.
5642 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
5643 to deal with it. Adjust comments.

5654 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
5656 Fix export of symbols to GDB (Bug#12036).
5657 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
5658 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5659 emacs.c, as this is a more-suitable home. Had this been done earlier
5660 the fix for 12036 would have avoided some of the problems noted in
5661 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5662 would have been more obvious.
5663 * emacs.c: Do not include <verify.h>; no longer needed.
5664 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5665 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5666 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5667 Remove; now done in lisp.h.

5672 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5673 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5674 not be usable in #if. This simplifies things.
5676 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5678 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
5680 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

5683 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5684 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5685 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5686 Adjust to changes in lisp.h and emacs.c, by using
5687 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5688 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5689 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5690 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5691 instead of gdb_valbits.
5692 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5693 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5694 instead of gdb_array_mark_flag.
5695 (xboolvector): Get size from $->size, not $->header.size.
5696 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5697 (xreload, hook-run, hookpost-run): Remove.
5698 * emacs.c: Include <verify.h>.
5699 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5700 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5702 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5703 (gdb_USE_LSB_TAG): New enum constants.
5704 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5705 Also define these as enum constants, so they're visible to GDB.
5706 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5707 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5708 as constants, so they're visible to GDB.
5709 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
5710 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5711 Now enum constants, not macros, so they're visible to GDB.
5712 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5713 more convenient now. All uses changed.
5714 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5715 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5717 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
5719 Explicitly free restriction data that are not needed anymore.
5720 * editfns.c (save_restriction_restore): Free restriction data.
5722 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
5724 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5725 add argument, tune behavior, and adjust all callers.
5727 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5729 Use typedef for EMACS_INT, EMACS_UINT.
5730 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5731 than macros. This simplifies debugging in the usual case, since
5732 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5733 and it allows expressions involving EMACS_INT casts.
5734 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5736 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5744 that FOCUS-FRAME can be omitted.
5746 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5748 Adjust buffer text indirection counters at the end of Fkill_buffer.
5749 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5750 buffer is definitely dead. This should really fix an issue reported
5751 by Christoph Scholtes again. (Bug#12007).
5752 (init_buffer_once): Initialize indirection counters of
5753 buffer_defaults and buffer_local_symbols (for sanity and safety).
5755 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5757 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5758 and continuation glyphs on tooltip frames, leave them at zero.
5759 Avoids continued lines in tooltips. (Bug#11832)
5761 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
5763 Simplify copy_overlay.
5764 * buffer.c (copy_overlay): Simplify. Use build_marker.

5770 or invalid. (Bug#12025)
5772 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
5773 it signals an error when a tooltip frame is being created.
5775 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5777 Cleanup miscellaneous objects allocation and initialization.
5778 * alloc.c (allocate_misc): Change to static. Add argument to
5779 specify the subtype. Adjust comment and users.
5780 (build_overlay): New function.
5781 * buffer.c (copy_overlays, Fmake_overlay): Use it.
5782 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
5783 (allocate_misc): Remove prototype.
5784 (build_overlay): Add prototype.
5786 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5788 Swap buffer text indirection counters in Fbuffer_swap_text.
5789 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5790 This avoids crash reported by Christoph Scholtes at
5791 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5793 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5795 * nsmenu.m (Popdown_data): New struct.
5796 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
5798 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
5799 (initWithContentRect): Make imgView and contentView non-static
5800 and autorelease them. Also autorelease img and matrix (Bug#12005).
5801 (dealloc): Remove (Bug#12005).
5803 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
5805 Adjust consing_since_gc when objects are explicitly freed.
5806 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
5807 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
5808 (free_cons, free_misc): Subtract object size from consing_since_gc.
5810 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

5814 (live_buffer, set_marker_internal): New function.
5815 (Fset_marker, set_marker_restricted): Use set_marker_internal.
5816 (set_marker_both, set_marker_restricted_both): Use live_buffer.
5818 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5820 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5821 as it's limited by the amount of memory, not by INT_MAX.

6549 * s/aix4-2.h (unix): Remove; no longer needed.
6551 EMACS_TIME simplification (Bug#11875).
6552 This replaces macros (which typically do not work in GDB)
6553 with functions, typedefs and enums, making the code easier to debug.
6554 The functional style also makes code easier to read and maintain.
6555 * systime.h: Include <sys/time.h> on all hosts, not just if
6556 WINDOWSNT, since 'struct timeval' is needed in general.

6569 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
6570 not functions. All uses rewritten to use the following, respectively:
6571 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
6572 (add_emacs_time, sub_emacs_time): New functions.
6573 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

6596 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6597 Prefer snprintf to strncpy.
6598 * nsterm.m (ns_term_init):
6599 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6600 * nsterm.m (ns_term_init):
6601 Avoid the need for strncpy, by using build_string or
6602 make_unibyte_string directly. Use dtoastr, not snprintf.
6603 * process.c (Fmake_network_process): Diagnose service names that
6604 are too long, rather than silently truncating them or creating
6605 non-null-terminated names.
6606 (Fnetwork_interface_info): Likewise, for interface names.
6607 * sysdep.c (system_process_attributes) [GNU_LINUX]:
6608 Prefer sprintf to strncat.

6621 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
6622 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6623 where argument type is known to be a Lisp_Cons.

6639 the function is called with compile-time constant argument.
6640 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
6641 argument, adjust users accordingly. Use build_pure_c_string where

6675 We include usg5-4-common.h, which defines them both.
6677 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
6678 O_RDONLY already includes it).
6680 Stop ns builds setting the EMACSLOADPATH environment variable.
6681 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6682 Now it does not set EMACSLOADPATH, just returns the load-path string.
6683 * nsterm.h: Update accordingly.
6684 * lread.c [HAVE_NS]: Include nsterm.h.
6685 (init_lread) [HAVE_NS]: Use ns_load_path.

6688 2012-07-09 Glenn Morris <rgm@gnu.org>
6690 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,

6695 (ns_init_paths): Do not set EMACSPATH.
6696 * nsterm.h (ns_exec_path): Add it.
6697 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6700 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6702 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>

6724 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6726 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6728 Use make_formatted_string to avoid double length calculation.
6729 * lisp.h (make_formatted_string): New prototype.
6730 * alloc.c (make_formatted_string): New function.
6731 * buffer.c (Fgenerate_new_buffer_name): Use it.

6734 * filelock.c (get_boot_time): Likewise.
6735 * frame.c (make_terminal_frame, set_term_frame_name)
6736 (x_report_frame_params): Likewise.

6749 * nsterm.h (ns_etc_directory): Add it.
6750 * callproc.c [HAVE_NS]: Include nsterm.h.
6751 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
6753 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6755 Move marker debugging code under MARKER_DEBUG.
6756 * marker.c (MARKER_DEBUG): Move marker debugging code under
6757 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6758 for bootstrap with --enable-checking (~3x slowdown reported
6759 by Juanma Barranquero <lekktu@gmail.com>).
6760 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6762 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6764 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6765 See <http://bugs.gnu.org/11825#29>.
6767 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6769 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6770 has no font, use the frame's font. (Bug#11813)
6771 (display_line): Add commentary about displaying truncation glyphs
6773 (produce_special_glyphs): Move here from term.c.
6775 * term.c (produce_special_glyphs): Move to xdisp.c.
6777 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6780 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6782 * xdisp.c (display_line): Avoid warning about implicit declaration
6785 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6787 * lisp.h: Remove empty conditional.
6789 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6791 * lread.c (load_path_check): Now static.
6793 Fix some minor --with-ns problems found by static checking.
6794 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6795 (x_set_font) [!HAVE_X_WINDOWS]:
6796 * image.c (xpm_load_image) [HAVE_NS]:
6797 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6798 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6799 Remove unused local.
6800 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6801 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6802 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6803 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6804 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):

6808 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6810 2012-07-07 Glenn Morris <rgm@gnu.org>
6812 * lread.c (load_path_check): New function, split from init_lread.
6813 (init_lread): Reorganize. Motivation:
6814 If EMACSLOADPATH is set, check/warn about that rather than the
6815 defaults, which we are not going to use. Hence we can remove
6816 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6817 Don't warn if site-lisp directories are missing.
6818 If not installed, start from a blank load-path, since
6819 PATH_LOADSEARCH refers to the eventual installation directories.
6821 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6823 Support truncation and continuation glyphs on GUI frames, when
6824 fringes are disabled. (Bug#11832)
6825 * xdisp.c (init_iterator): Get dimensions of truncation and
6826 continuation glyphs even if on GUI frames.
6827 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6828 or both, are absent.
6829 (start_display, move_it_in_display_line_to): Handle the case of a
6830 GUI frame without a fringe to display continuation or truncation
6832 (insert_left_trunc_glyphs): Support GUI frames: make sure
6833 truncation glyphs overwrite enough glyphs from the current line to
6834 have sufficient space in pixels.
6835 (display_line): Support truncation and continuation glyphs on GUI
6836 frames. If some spare pixels are left on the line after inserting
6837 the truncation glyphs, fill that space with a stretch glyph of a
6838 suitably computed width.
6840 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6841 produce_glyphs, to support GUI sessions.
6843 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6845 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6847 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6849 Do not require float-time's arg to fit in time_t (Bug#11825).
6850 This works better on hosts where time_t is unsigned, and where
6851 float-time is applied to the (negative) difference between two times.
6852 * editfns.c (decode_time_components): Last arg is now double *,
6853 not int *, and means to store all the result as a double, without
6854 worrying about whether the seconds part fits in time_t.
6855 All callers changed.
6856 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6857 All callers changed.
6858 (Ffloat_time): Do not fail merely because the specified time falls
6859 outside of time_t range.
6861 2012-07-07 Glenn Morris <rgm@gnu.org>
6863 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

6870 Update dependencies.
6872 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6874 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6876 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

6878 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6879 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6880 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

6883 * xfont.c (compare_font_names): Redo to omit the need for casts.
6885 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6887 * xfns.c (Fx_change_window_property): Doc fix.
6888 * w32fns.c (Fx_change_window_property): Doc fix.
6890 * w32fns.c (Fx_window_property): Accept the same arguments as the
6891 X Windows version. Doc fix.
6892 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6894 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6895 Eli Zaretskii <eliz@gnu.org>
6897 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6898 Windows-specific code from nt/config.nt moved here.
6899 Obsolete settings removed.
6901 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6903 * process.c: Avoid unnecessary calls to gettime.
6904 (wait_reading_process_output): Don't get the time of day
6905 when gobbling data immediately and not waiting, as there's no need
6906 for it in that case. This removes a FIXME.
6908 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6910 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6911 is defined (Bug#11768).
6913 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6915 Fix marker debugging code.
6916 * marker.c (byte_char_debug_check): Do not perform the check
6917 if buffer is not multibyte.
6918 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6919 Call byte_char_debug_check with correct arguments.
6921 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6923 Compile marker debugging code only if ENABLE_CHECKING is defined.
6924 * marker.c (byte_char_debug_check, count_markers):
6925 Use only if ENABLE_CHECKING is defined.
6926 (byte_debug_flag): Remove.
6927 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6928 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6930 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6932 Avoid code repetition in marker-related functions.
6933 * marker.c (attach_marker): New function.
6934 (Fset_marker, set_marker_restricted, set_marker_both)
6935 (set_marker_restricted_both): Use it.
6936 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6937 Consistently rename charno to charpos.
6938 (marker_position): Add eassert.
6939 (marker_byte_position): Convert to eassert.

6955 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6956 (save_restriction_save): Use build_marker.
6957 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6958 * window.c (save_window_save): Likewise.
6960 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6962 Do not use Fdelete_overlay in delete_all_overlays
6963 to avoid redundant calls to unchain_overlay.
6964 * buffer.c (drop_overlay): New function.
6965 (delete_all_overlays, Fdelete_overlay): Use it.
6966 * minibuf.c (get_minibuffer): Fix comment.
6968 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6970 Port to OpenBSD 5.1 amd64.
6971 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6972 This is needed for OpenBSD, and should be harmless on all BSD systems.
6973 Also, include <sys/sysctl.h>, as it should be available on all
6974 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6975 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6976 use p_pid member, not kp_proc.pid.
6978 2012-07-06 Glenn Morris <rgm@gnu.org>
6980 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6982 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6984 More xmalloc and related cleanup.
6985 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

6993 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6995 Omit needless casts involving void * pointers and allocation.
6996 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6997 as the former is more robust if P's type is changed.
6998 Prefer xzalloc to xmalloc + memset 0.
6999 Simplify malloc-or-realloc to realloc.
7000 Don't worry about xmalloc returning a null pointer.
7001 Prefer xstrdup to xmalloc + strcpy.
7002 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7004 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7005 alloca of a constant.
7007 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7009 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7010 hscroll is larger than the line width. Fixes long and futile
7011 looping inside extend_face_to_end_of_line (on a TTY) producing
7012 glyphs that are not needed and thrown away.
7014 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7016 * marker.c (set_marker_restricted_both): Simplify by using
7019 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

7031 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7032 (update_theme_scrollbar_width, xg_create_scroll_bar):
7033 Use gtk_scrollbar_new (Bug#11768).

7036 (xg_tool_item_stale_p): Call is_box_type.
7037 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
7038 with default display (Bug#11768).

7042 * xdisp.c (window_hscroll_limited): New function.
7043 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7044 coordinates when window's hscroll is set to insanely large
7047 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7049 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

7116 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7117 This should be fixed in a better way; see Eli Zaretskii in
7118 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7119 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7121 * fileio.c (time_error_value): Rename from special_mtime.
7122 The old name's problems were noted by Eli Zaretskii in
7123 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7125 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7126 This variable's comment says Emacs needs at least one GDB-visible
7127 symbol of type enum pvec_type, to work around GDB problems.
7128 The symbol's value doesn't matter.
7130 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7131 that causes compilation to fail on pre-C99 compilers.
7133 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

7158 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7159 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7160 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7161 abusing vector->header.next.nbytes.
7162 (live_vector_p): Use PVEC_TYPE.
7163 (mark_object): Adapt code to extract pvectype. Use switch.
7165 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7167 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7168 Tighten new eassert a bit.
7170 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7172 Fix compilation with --enable-gcc-warnings and -O1
7174 * doprnt.c (doprnt): Change type of tem to int, initialize
7175 to avoid compiler warning. Add eassert.
7176 * search.c (simple_search): Initialize match_byte to avoid
7177 compiler warning. Add eassert.
7179 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7181 Avoid weird behavior with large horizontal scrolls.
7182 Without this change, for example, large hscroll values would
7183 mess up Emacs's display on Fedora 15 x86, presumably due to
7184 overflows in int calculations in the display code.
7185 Also, if buffers had long lines, Emacs would freeze.
7186 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7187 (set_window_hscroll): New function, containing the old guts of
7188 Fset_window_hscroll. Return the clipped value.
7189 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7190 This avoids the need to check against PTRDIFF_MAX.
7192 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7194 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7196 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7198 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7200 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7201 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7202 since GCC 4.4.6 issues a bogus warning for them.
7204 Fix bugs in file timestamp newness comparisons.
7205 * fileio.c (Ffile_newer_than_file_p):
7206 * lread.c (Fload): Use full timestamp resolution of files,
7207 not just the 1-second resolution, so that files that are only
7208 slightly newer still count as newer.
7209 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7210 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7212 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7214 * fileio.c: Improve handling of file time marker. (Bug#11852)
7215 (special_mtime): New function.
7216 (Finsert_file_contents, Fverify_visited_file_modtime):
7217 Use it to set special mtime values consistently.
7219 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7221 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7222 marker for non-existing file. (Bug#11852)
7224 2012-07-03 Glenn Morris <rgm@gnu.org>
7226 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7227 and did not make it into globals.h).
7229 2012-07-03 Tom Tromey <tromey@redhat.com>
7231 * window.c (Fset_window_margins, Fset_window_fringes)
7232 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7233 * textprop.c (Fprevious_property_change): No longer static.
7234 * syntax.c (Fsyntax_table_p): No longer static.

7263 * window.h: Remove EXFUNs.

7267 2012-07-03 Glenn Morris <rgm@gnu.org>
7269 * lisp.h (Frandom): Make it visible to C.

7271 buffer for invisible buffers. (Bug#1229)
7273 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7275 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7276 values which aren't power of 2.
7277 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7278 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7281 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7283 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7285 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7287 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7289 * alloc.c (allocate_vector_block): Remove redundant
7290 calls to mallopt if DOUG_LEA_MALLOC is defined.
7291 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7292 avoid calls to mallopt if zero_vector is returned.
7294 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7296 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7297 is enabled, avoid dereferencing NULL current_sblock if
7300 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7302 Cleanup basic buffer management.
7303 * buffer.h (struct buffer): Change layout to use generic vector
7304 marking code. Fix some comments. Change type of 'clip_changed'
7305 to bitfield. Remove unused #ifndef old.
7306 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7307 (GET_OVERLAYS_AT): Fix indentation.
7308 (for_each_per_buffer_object_at): New macro.
7309 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
7310 (Fbuffer_local_variables): Use it.
7311 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
7312 * alloc.c (allocate_buffer): Adjust to match new layout of
7313 struct buffer. Fix comment.
7314 (mark_overlay): New function.
7315 (mark_buffer): Use it. Use mark_vectorlike to mark normal
7316 Lisp area of struct buffer.
7317 (mark_object): Use it. Adjust marking of misc objects
7318 and related comments.
7320 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7322 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7323 wrapper that is not needed because the wrapped code is a no-op (zero
7324 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7325 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7327 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7329 * alloc.c (mark_buffer): Simplify. Remove prototype.
7330 (mark_object): Add comment. Reorganize marking of vector-like
7331 objects. Use CHECK_LIVE for all vector-like objects except buffers
7332 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7333 Avoid redundant calls to mark_vectorlike for bool vectors.
7335 2012-06-30 Glenn Morris <rgm@gnu.org>
7337 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7339 * epaths.in (PATH_SITELOADSEARCH): New.
7340 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7341 This is rather than relying on --enable-locallisppath elements
7342 having "site-lisp" in their names. (Bug#10208#25, 11658)
7344 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7346 * w32proc.c (sys_select): Accept and ignore one more argument.
7348 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7350 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7351 (pselect) [!MS_DOS]: Redirect to sys_select.
7353 * sysdep.c: Don't include dos.h and dosfns.h.
7355 * process.c (sys_select):
7356 * msdos.c (sys_select): Accept one more argument and ignore it.
7358 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7359 adapt data types and code to that.
7362 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7363 which clashes with the gnulib function of the same name.
7365 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7367 * font.c (font_style_to_value, font_style_symbolic)
7368 (font_prop_validate_style): Add type checks for values in
7371 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7373 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7376 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7378 * xdisp.c (try_window_id): Undo last change.
7380 * w32.c (getwd): Adjust commentary about startup_dir.
7381 (init_environment): Always call sys_access, even in non-MSVC
7382 builds. Don't chdir to the directory of the Emacs executable.
7383 This undoes code from 1997 which was justified by the need to
7384 "avoid conflicts when removing and renaming directories". But its
7385 downside was that every relative file name was being interpreted
7386 relative to the directory of the Emacs executable, which can never
7387 be TRT. In particular, it broke sys_access when called with
7388 relative file names.
7389 (sys_access): Map GetLastError to errno.
7391 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7393 * window.h (struct window): Change type of 'fringes_outside_margins'

7397 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7400 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
7402 * gnutls.c (emacs_gnutls_handshake):
7403 Add QUIT to make the loop interruptible.
7405 2012-06-29 Glenn Morris <rgm@gnu.org>
7407 * charset.c (init_charset): Make lack of etc/charsets fatal.
7409 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7411 * editfns.c (region_limit): Fix type mismatch.
7413 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7415 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
7416 undefined. Convert from xassert to eassert.
7417 * nsmenu.m: Convert from xassert to eassert.
7418 * nsterm.m: Likewise.
7420 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7422 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7424 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7426 Avoid integer overflow on scroll-left and scroll-right.
7427 * window.c (HSCROLL_MAX): New macro.
7428 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7429 overflow when requested scroll falls outside ptrdiff_t range.
7431 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7433 * window.h (struct window): Change type of 'hscroll',
7434 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7435 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7436 Adjust users accordingly.
7437 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7438 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7439 from EMACS_INT to ptrdiff_t.
7440 (make_window): Omit redundant initialization.
7442 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

7446 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7448 * window.h (struct window): Change type of 'use_time' and

7511 avoid GCC warning about unused macro.

7515 * alloc.c (allocate_string): Omit intervals initialization.
7516 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7517 as in make_pure_string and make_pure_c_string.
7519 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
7521 * alloc.c (allocate_string): Fix last change.
7523 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

7573 * alloc.c: Remove build_string.
7574 * lisp.h: Define build_string as static inline. This provides
7575 a better opportunity to optimize away calls to strlen when the
7576 function is called with compile-time constant argument.
7577 * image.c (imagemagick_error): Convert to build_string.
7578 * w32proc.c (sys_spawnve): Likewise.
7579 * xterm.c (x_term_init): Likewise.
7581 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7583 Use sprintf return value instead of invoking strlen on result.
7584 In the old days this wasn't portable, since some sprintf
7585 implementations returned char *. But they died out years ago and
7586 Emacs already assumes sprintf returns int.
7587 Similarly for float_to_string.
7588 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
7589 * ccl.c (ccl_driver):
7590 * character.c (string_escape_byte8):

7595 * xfns.c (syms_of_xfns):
7596 Use sprintf or float_to_string result to avoid need to call strlen.
7597 * data.c (Fnumber_to_string):
7598 Use make_unibyte_string, since the string must be ASCII.
7599 * lisp.h, print.c (float_to_string): Now returns int length.
7600 * term.c (produce_glyphless_glyph):
7601 Use sprintf result rather than recomputing it.
7603 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7604 * Makefile.in (ALL_CFLAGS):

7636 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

7641 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7642 instead of truncating it to 63 (admittedly a generous limit).
7644 * process.c: Fix spelling and caps in comments.

7772 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7774 Support higher-resolution time stamps (Bug#9000).
7775 The time stamps are only nanosecond-resolution at the C level,
7776 since that's the best that any real-world system supports now.
7777 But they are picosecond-resolution at the Lisp level, as that's
7778 easy, and leaves room for future OS improvements.
7780 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7783 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7784 Don't get current time unless it's needed.
7786 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7787 now provides it if it's absent.
7788 (start_atimer): Port to higher-res time stamps.
7789 Check for time stamp overflow. Don't get current time more
7790 often than is needed.
7792 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7793 Include systime.h, not time.h.
7794 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7796 * dired.c: Include stat-time.h.
7797 (Ffile-attributes): File times now have higher resolution.

7800 (struct image): Timestamp now has higher resolution.
7802 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7803 has at least microseconds now. All uses removed.
7804 (update_frame, update_single_window, update_window, update_frame_1)
7805 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7806 (duration_to_sec_usec): Remove; no longer needed.
7808 * editfns.c (time_overflow): Now extern.

7814 (decode_time_components, lisp_seconds_argument): New functions.
7815 (make_time): Now static.
7816 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7817 Report an error if the time is invalid, rather than having the caller
7820 * fileio.c: Include <stat-time.h>
7821 (Fcopy_file): Copy higher-resolution time stamps.
7822 Prefer to set the time stamp via a file descriptor if that works.

7824 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7825 (Fvisited_file_modtime, Fset_visited_file_modtime):
7826 Support higher-resolution time stamps.
7828 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7830 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7832 * image.c (prepare_image_for_display, clear_image_cache)
7833 (lookup_image): Port to higer-resolution time stamps.
7835 * keyboard.c (start_polling, bind_polling_period):
7836 Check for time stamp overflow.
7837 (read_char, kbd_buffer_get_event, timer_start_idle)
7838 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7839 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7840 Port to higher-resolution time stamps. Do not assume time_t is signed.
7841 (decode_timer): New function. Timers are now vectors of length 9,
7842 not 8, to accommodate the picosecond component.
7843 (timer_check_2): Use it.
7845 * nsterm.m (select_timeout, timeval_subtract): Remove.
7846 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7847 as they're a bit more accurate and handle overflow better.
7848 (ns_select): Change prototype to be compatible with pselect.
7849 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7850 * nsterm.h (ns_select): Adjust prototype.
7852 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7853 us-resolution time stamps.
7854 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7856 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7858 * lisp.h (time_overflow): New decl.
7859 (wait_reading_process_output): First arg is now intmax_t, not int,
7860 to accommodate larger waits.
7862 * process.h (struct Lisp_Process.read_output_delay):
7863 Now counts nanoseconds, not microseconds.
7864 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7866 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7867 (wait_reading_process_output):
7868 Port to ns-resolution time stamps.
7869 (Faccept_process_output, wait_reading_process_output):
7870 Check for time stamp overflow. Do not assume time_t is signed.
7871 (select_wrapper): Remove; we now use pselect.
7872 (Fprocess_attributes): Now generates ns-resolution time stamps.
7874 * sysdep.c: Include utimens.h. Don't include utime.h
7875 or worry about struct utimbuf; gnulib does that for us now.
7876 (gettimeofday): Remove; gnulib provides a substitute.
7877 (make_timeval): New function.
7878 (set_file_times): Now sets ns-resolution time stamps.
7879 New arg FD; all uses changed.
7880 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7881 (system_process_attributes):
7882 Now returns ns-resolution time stamp. All uses changed.
7883 Check for time stamp overflow.
7885 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7886 provides a substitute now.
7888 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7889 since it guarantees struct timespec.
7890 (EMACS_TIME): Now struct timespec, so that we can support
7891 ns-resolution time stamps.
7892 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7893 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7894 (EMACS_USECS): Remove.
7895 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7896 so multiply the arg by 1000 before storing it.
7897 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7899 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7900 Port to ns-resolution time stamps.
7901 (EMACS_TIME_NEG_P): Remove; replaced by....
7902 (EMACS_TIME_SIGN): New macro.
7903 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7904 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7905 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7906 (make_timeval, make_lisp_time, decode_time_components): New decls.
7907 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7908 that it mishandled time_t overflow. You can't compare by subtracting!
7909 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7910 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7912 * term.c: Include <sys/time.h>.

7918 (Fprimitive_undo): Use them when restoring time stamps.
7920 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7921 (w32_get_internal_run_time):
7922 Port to higher-resolution Emacs time stamps.
7923 (ltime): Now accepts single 64-bit integer, as that's more convenient
7926 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7928 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7929 for compatibility with pselect. Support ns-resolution time stamps.
7931 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7933 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7934 Check for time stamp overflow, and support ns-resolution time stamps.
7936 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7937 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7938 (timeval_subtract): Remove; no longer needed.
7939 (XTflash, XTring_bell, x_wait_for_event):
7940 Port to ns-resolution time stamps. Don't assume time_t is signed.
7942 2012-06-22 Chong Yidong <cyd@gnu.org>

7946 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7948 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7949 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7950 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7951 staticidx goes up to 1597 out of 1600 = 0x640.)
7953 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7955 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7956 Otherwise, the umask might be mistakenly 0 while handling input signals.

7978 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7980 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

8001 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8002 gets killed during executing of this function (Bug#11665).
8003 Try to always return Qt when the buffer has been actually killed.
8004 (Vkill_buffer_query_functions): In doc-string say that functions
8005 run by this hook should not change the current buffer.
8007 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8027 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
8029 * lisp.h (eassert): Assume C89 or later.
8030 This removes the need for CHECK.
8031 (CHECK): Remove. Its comments about always evaluating its
8032 argument were confusing, as 'eassert' typically does not evaluate
8035 * coding.c (produce_chars): Use ptrdiff_t, not int.
8037 * xterm.c (x_draw_underwave): Check for integer overflow.
8038 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

8167 (TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.
8168 (make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler.

8177 * s/usg5-4-common.h (USG5_4): No longer define; unused.
8179 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
8181 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
8184 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
8186 * emacs.c (gdb_use_struct): Rename from gdb_use_union.

8190 * frame.c (delete_frame): Remove outdated comment.
8191 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
8192 USE_LISP_UNION_TYPE.

8211 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
8212 * alloc.c (make_number) [!defined make_number]:
8213 Remove, as lisp.h always defines this now.

8216 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
8217 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.

8220 USE_LSB_TAG now is always defined to be either 0 or 1.
8222 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
8223 code works fine either way, and efficiency is not a concern here,
8224 as the union type is for debugging, not for production.
8225 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8226 Use an inline function on all platforms when using the union type,
8227 since this is simpler and 'static inline' can be used portably
8229 (LISP_INITIALLY_ZERO): New macro.
8230 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
8231 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

8257 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/darwin.h:
8258 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
8259 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
8260 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

8299 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
8300 dbus_type_is_basic if available.
8301 (xd_extract_signed, xd_extract_unsigned): Rename from
8302 extract_signed and extract_unsigned, respectively. Adapt callers.
8304 2012-06-09 Chong Yidong <cyd@gnu.org>

8313 * xdisp.c (vmessage): Treat frame message as multibyte.
8314 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
8315 would generate the diagnostic "Making \302\247 buffer-local while

8333 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
8334 function warning (the only call is inside #if 0 since revno:108521).
8336 2012-06-08 Eli Zaretskii <eliz@gnu.org>
8338 * alloc.c (allocate_vectorlike): Fix last change.
8340 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
8342 Block-based vector allocation of small vectors.
8343 * lisp.h (struct vectorlike_header): New field `nbytes',
8344 adjust comment accordingly.
8345 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

8367 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
8369 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
8371 * doprnt.c (doprnt): Truncate multibyte char correctly.
8372 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8373 would mishandle a string argument "Xc" if X was a multibyte
8374 character of length 2: it would truncate after X's first byte
8375 rather than including all of X.
8377 2012-06-06 Chong Yidong <cyd@gnu.org>
8379 * buffer.c (word_wrap): Doc fix.

8428 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8429 Convert pctcpu and pctmem to Lisp float properly.
8430 Let the compiler fold better, as 100.0/0x8000 is exact.
8432 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8434 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
8437 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
8439 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
8441 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
8443 For a 'struct window', replace some Lisp_Object fields to
8444 bitfields where appropriate, remove unused fields.
8445 * window.h (struct window): Remove unused 'last_mark_x' and
8446 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
8447 change its type from Lisp_Object to bitfield.
8448 Change type of 'force_start', 'optional_new_start',
8449 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8450 fields from Lisp_Object to bitfield. Adjust users accordingly.
8452 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8454 Pacify gcc -Wdouble-precision when using Xaw.
8455 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
8456 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
8457 Use 'float' consistently, rather than 'float' in most places
8458 and 'double' in a couple of places.
8460 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8462 * xdisp.c (handle_stop): Detect whether we have overlay strings
8463 loaded by testing it->current.overlay_string_index to be
8464 non-negative, instead of checking whether n_overlay_strings is
8465 positive. (Bug#11587)
8467 2012-05-31 Chong Yidong <cyd@gnu.org>
8469 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
8471 * doc.c (Fsubstitute_command_keys): Doc fix.
8473 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8475 * search.c (search_buffer): Remove calls to
8476 r_alloc_inhibit_buffer_relocation, as it is now called by
8477 maybe_unify_char, which was the cause of relocation of buffer text
8480 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8482 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8483 for the duration of call to load_charset, to avoid problems with
8484 callers of maybe_unify_char that access buffer text through C
8487 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8488 decrement the inhibition flag, instead of just setting or
8491 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8493 Remove obsolete '#define static' cruft.
8494 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8495 This #undef was "temporary" in 2000; it is no longer needed
8496 now that '#define static' has gone away.
8497 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8498 (gray_bitmap_bits): Remove; no longer needed.
8499 All uses replaced with definiens.
8500 * xterm.c: Include "bitmaps/gray.xbm".
8502 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8504 Clean up __executable_start, monstartup when --enable-profiling.
8505 The following changes affect the code only when profiling.
8506 * dispnew.c (__executable_start): Rename from safe_bcopy.
8507 Define only on platforms that need it.
8508 * emacs.c: Include <sys/gmon.h> when profiling.
8509 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
8510 (__executable_start): Remove decl, since lisp.h does it now.
8511 (safe_bcopy): Remove decl; no longer has that name.
8512 (main): Coalesce #if into single bit of code, for simplicity.
8513 Cast pointers to uintptr_t, since standard libraries want integers

8538 * lread.c (read1): Tiny simplification.
8540 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
8542 Do not create empty overlays with the evaporate property (Bug#9642).
8543 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8544 Bug#9642, but explicitly check that the buffer the overlay would
8545 be moved to is live and rearrange lines to make sure that errors
8546 will not put the overlay in an inconsistent state.
8547 (Fdelete_overlay): Cosmetics.
8549 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8551 * w32term.c (my_bring_window_to_top): New function.
8552 (x_raise_frame): Use handle returned by DeferWindowPos, which
8553 could be different from the original one.

8557 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
8558 by calling BringWindowToTop.

8563 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
8565 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
8566 This avoids undefined behavior that might cause the eassert
8567 to not catch an out-of-range value.
8569 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8571 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

8581 when referring to sectname field in printf format.
8583 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
8585 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8586 Only r_alloc_inhibit_buffer_relocation needed to be added;
8587 the others were already declared.
8589 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8590 before checking whether it's out of range. Put the check inside
8592 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8594 2012-05-27 Ken Brown <kbrown@cornell.edu>
8596 * callproc.c (Fcall_process): Restore a line that was accidentally
8597 commented out in the 2011-02-13 change (bug#11547).

8601 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8602 defined on ralloc.c.
8604 * buffer.c [REL_ALLOC]: Remove prototypes of
8605 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8606 they are now on lisp.h.
8608 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8610 * search.c (search_buffer): Use it to inhibit relocation of buffer
8611 text while re_search_2 is doing its job, because re_search_2 is
8612 passed C pointers to buffer text. (Bug#11519)
8614 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8617 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8618 state after an additional call to move_it_in_display_line_to, keep
8619 the values of it->max_ascent and it->max_descent found for the
8621 (pos_visible_p): Revert the comparison against bottom_y to what it
8622 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8625 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8627 Fix coding-related core dumps with gcc -ftrapv.
8628 The code was computing A - B, where A and B are pointers, and B is
8629 random garbage. This can lead to core dumps on platforms that
8630 have special pointer registers, and it also leads to core dumps on
8631 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8632 A - B only when B is initialized properly.

8656 gen_help_event to produce help-echo message in the echo area.
8657 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8660 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8662 * lread.c (read1): Simplify slightly to avoid an overflow warning
8663 with GCC 4.7.0 on x86-64.
8665 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8667 * bidi.c (bidi_mirror_char): Revert last change: an int is
8668 definitely wide enough here.
8670 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
8672 Fix integer width and related bugs (Bug#9874).

8684 Use int, not EMACS_INT, where int is wide enough.

8704 (Foverlay_recenter, last_overlay_modification_hooks_used)
8705 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8706 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8707 (validate_region): Omit unnecessary test for b <= e,
8708 since that's guaranteed by the previous test.
8709 (adjust_overlays_for_delete): Avoid pos + length overflow.
8710 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8711 (report_overlay_modification):
8712 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8713 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

8722 not int, to avoid needless 32-bit limit on 64-bit hosts.
8723 (exec_byte_code): Use tighter memory-full test, one that checks
8724 for alloca overflow. Don't compute the address of the object just
8725 before an array, as that's not portable. Use EMACS_INT, not
8726 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8727 * callint.c (Fcall_interactively):
8728 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8740 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8741 (casify_object): Avoid integer overflow when overallocating buffer.
8742 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

8745 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8746 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

8750 For CCL_MapSingle, check that content and value are in int range.

8752 Check that Vcode_version_map_vector is a vector.
8753 (resolve_symbol_ccl_program): Check that vector header is in range.
8754 Always copy the vector, so that we can check its contents reliably
8755 now rather than having to recheck each instruction as it's being
8756 executed. Check that vector words fit in 'int'.
8757 (ccl_get_compiled_code, Fregister_ccl_program)
8758 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8759 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

8761 contents are in range.
8762 (Fccl_execute_on_string): Check that status is in range.
8763 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8764 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8765 Accept and return EMACS_INT, not int, because callers can pass values

8772 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8774 avoid mishandling large integers.
8775 * character.h: Adjust decls to match defn changes elsewhere.

8785 Don't rely on undefined behavior with signed left shift overflow.
8786 Don't assume unsigned int fits into fixnum, or that fixnum fits
8787 into unsigned int. Don't require max_code to be a valid fixnum;
8788 that's not true for gb10830 4-byte on a 32-bit host. Allow
8789 invalid_code to be a cons, for the same reason. Require code_offset
8790 to be a character. Avoid int overflow if max_char is close
8792 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8793 this is intended anyway and avoids some undefined behavior.
8794 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8795 INDEX_TO_CODE_POINT, as that's what it expects.
8796 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8797 * charset.h (DECODE_CHAR): Return int, not unsigned;
8798 this is what was intended anyway, and it avoids undefined behavior.
8799 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8800 integer-overflow issues.
8801 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8802 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8803 where the argument is EMACS_INT, and this behavior is not intended.
8804 * chartab.c (Fmake_char_table, Fset_char_table_range)
8805 (uniprop_get_decoder, uniprop_get_encoder):
8806 Don't assume fixnum fits in int.
8807 * cmds.c (move_point): New function, that does the gist of
8808 Fforward_char and Fbackward_char, but does so while checking
8809 for integer overflow more accurately.
8810 (Fforward_char, Fbackward_char): Use it.
8811 (Fforward_line, Fend_of_line, internal_self_insert)
8812 (internal_self_insert):
8813 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9594 2012-05-14 Glenn Morris <rgm@gnu.org>
9596 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9597 Put "libexec" before "bin", for the sake of init_callproc_1.
9599 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9601 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

9604 (report_error, report_error_1, make_hdr, copy_sym)
9605 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9606 Make arguments const char *, not char *, to avoid violations of C
9607 standard and to fix some AIX warnings reported by Gilles Pion.
9609 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9611 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9612 already have overlays loaded.
9613 (handle_single_display_spec): Before returning without displaying
9614 fringe bitmap, synchronize the bidi iterator with the main display
9615 iterator, by calling iterate_out_of_display_property.
9616 (iterate_out_of_display_property): Detect buffer iteration by
9617 testing that it->string is a Lisp string.
9618 (get_next_display_element): When the current object is exhausted,
9619 and there's something on it->stack, call set_iterator_to_next to
9620 proceed with what's on the stack, instead of returning zero.
9621 (set_iterator_to_next): If called at the end of a Lisp string,
9622 proceed to consider_string_end without incrementing string
9623 position. Don't increment display vector index past the end of
9624 the display vector. (Bug#11417)
9625 (pos_visible_p): Don't report a position visible when move_it_to
9626 stopped at the last line of window, which happens to be scanned
9627 backwards by the bidi iteration. (Bug#11464)
9629 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9631 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9632 and right-margin display specs even if the spec is invalid or we
9633 are on a TTY, and thus unable to display on the fringes.
9634 That's because the text with the property will not be displayed anyway,
9635 so we need to signal to the caller that this is a "replacing"
9636 display spec. This fixes display when the spec is invalid or we
9639 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9641 * unexaix.c (make_hdr): Fix typo in prototype.
9642 This bug broke the build on AIX. Problem reported by Gilles Pion.
9644 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9646 * keyboard.c (kbd_buffer_get_event): Read special events also in
9647 batch mode. (Bug#11415)
9649 2012-05-12 Glenn Morris <rgm@gnu.org>

9657 2012-05-12 Glenn Morris <rgm@gnu.org>
9659 * Makefile.in (MKDIR_P): New, set by configure.
9660 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9662 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9664 Remove unused function hourglass_started.

9672 Update dependencies.
9674 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9676 * xgselect.c (xg_select): Put maxfds+1 into a var.
9677 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9679 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9681 2012-05-10 Dave Abrahams <dave@boostpro.com>
9683 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9684 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9686 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9688 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9689 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9690 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9691 Initialize xd_registered_buses.
9693 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9695 Untag more efficiently if USE_LSB_TAG.
9696 This is based on a proposal by YAMAMOTO Mitsuharu in
9697 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9698 For an admittedly artificial (nth 8000 longlist) benchmark on
9699 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9700 Emacs's overall text size by 1%.
9701 * lisp.h (XUNTAG): New macro.
9702 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9703 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9704 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9705 * eval.c (Fautoload):
9706 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9707 * frame.h (XFRAME): Use XUNTAG.
9709 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9710 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9711 Remove unportable assumptions about print widths of types like
9713 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9714 intptr_t when converting between pointer and integer, to avoid GCC
9715 warnings about wrong width.
9717 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9719 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9720 stack for each reader_thread, instead of defaulting to 8MB
9721 determined by the linker. This avoids failures in creating
9722 subprocesses on Windows 7, see the discussion in this thread:
9723 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9725 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9727 Fix up display of the *Minibuf-0* buffer in the mini window.
9728 * keyboard.c (read_char): Don't clear the echo area if there's no
9730 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9731 contents of *Minibuf-0*) if there's no message displayed in its stead.
9733 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9735 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9738 2012-05-06 Chong Yidong <cyd@gnu.org>
9740 * lisp.mk (lisp): Update.
9742 2012-05-05 Jim Meyering <meyering@redhat.com>
9744 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9746 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9748 * data.c (PUT_ERROR): New macro.
9749 (syms_of_data): Use it. Add new error type `user-error'.
9750 * undo.c (user_error): New function.
9751 (Fprimitive_undo): Use it.
9752 * print.c (print_error_message): Adjust print style for `user-error'.
9753 * keyboard.c (user_error): New function.
9754 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9756 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9758 Do not limit current-time-string to years 1000..9999.
9759 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9760 (Fcurrent_time_string): Support any year that is supported by the
9761 underlying localtime representation. Don't use asctime, as it
9762 has undefined behavior for years outside the range -999..9999.
9764 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9766 Fix race conditions involving setenv, gmtime, localtime, asctime.
9767 Without this fix, interrupts could mess up code that uses these
9768 nonreentrant functions, since setting TZ invalidates existing
9769 tm_zone or tzname values, and since most of these functions return
9770 pointers to static storage.
9771 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9772 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9773 Grow the critical sections to include not just invoking
9774 localtime/gmtime, but also accessing these functions' results
9775 including their tm_zone values if any, and any related TZ setting.
9776 (format_time_string): Last arg is now struct tm *, not struct tm **,
9777 so that the struct tm is saved in the critical section.
9778 All callers changed. Simplify allocation of initial buffer, partly
9779 motivated by the fact that memory allocation needs to be outside
9780 the critical section.
9782 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9784 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9785 with RESET_INTERVAL.
9787 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9788 Remove duplicated buffer name initialization.
9790 2012-05-02 Jim Meyering <jim@meyering.net>
9792 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9794 * xfns.c (x_window): Use xstrdup (Bug#11375).
9796 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9798 * xdisp.c (pos_visible_p): If already at a newline from the
9799 display string before the 'while' loop, don't walk back the glyphs
9800 from it3.glyph_row. Solves assertion violation when the display
9801 string begins with a newline (egg.el). (Bug#11367)
9803 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9805 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9808 2012-05-01 Glenn Morris <rgm@gnu.org>
9810 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9811 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9812 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9813 All were removed before 23.1.
9815 * dispnew.c: Remove HAVE_LIBNCURSES test;
9816 it is always true on relevant platforms.
9818 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9819 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9821 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9823 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9825 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9826 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9829 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9831 Do not avoid creating empty evaporating overlays (Bug#9642).
9832 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9833 That is, do not delete an evaporating overlay if it becomes
9834 empty after its bounds are adjusted to fit within its buffer.
9835 This fix caused other problems, and I'm reverting it until we get
9836 to the bottom of them.
9838 2012-04-27 Chong Yidong <cyd@gnu.org>
9840 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9842 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9844 * xdisp.c (pos_visible_p): If the window start position is beyond
9845 ZV, start the display from buffer beginning. Prevents assertion
9846 violation in init_iterator when the minibuffer window is scrolled
9849 * window.c (window_scroll_pixel_based): Likewise.
9851 2012-04-27 Chong Yidong <cyd@gnu.org>
9853 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9855 2012-04-27 Glenn Morris <rgm@gnu.org>
9857 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9858 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9860 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9862 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9863 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9865 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9867 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9868 display element, check also the underlying string or buffer
9869 character. (Bug#11341)
9871 * w32menu.c: Include w32heap.h.
9872 (add_menu_item): If the call to AppendMenuW (via
9873 unicode_append_menu) fails, disable Unicode menus only if we are
9874 running on Windows 9X/Me.
9876 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9878 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9879 (xgetint): Add missing shift for LSB tags.
9881 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9883 * keyboard.c (read_char): Don't wipe echo area for select window
9884 events: These might get delayed via `mouse-autoselect-window'
9887 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9889 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9890 manipulation of :loaded-from data.
9892 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9894 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9895 now a cons (bug#11311).
9897 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9899 Do not create empty overlays with the evaporate property (Bug#9642).
9900 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9901 if it becomes empty after its bounds are adjusted to fit within
9902 its buffer. Without this fix, in a nonempty buffer (let ((o
9903 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9904 yields an empty overlay that has the evaporate property, which is
9905 not supposed to happen.
9907 Fix minor GTK3 problems found by static checking.
9908 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9909 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9910 (struct _EmacsFixedClass, emacs_fixed_get_type):

9918 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
9919 (EMACS_FIXED_GET_CLASS): Remove; unused.
9920 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9922 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9923 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9925 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9927 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9928 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9929 (__malloc_size_t, __malloc_ptrdiff_t):
9930 Remove. All uses removed, replaced by the definiens if needed,
9931 since we can assume C89 or better now.
9932 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
9933 (protect_malloc_state, align, get_contiguous_space)

9941 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9942 Define using prototypes, not old style.
9943 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9944 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

10007 * alloc.c: Handle unusual debugging option combinations.
10008 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
10009 since the two debugging options are incompatible.

10020 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10022 * sysdep.c [__FreeBSD__]: Minor cleanups.
10023 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10024 Use Emacs indenting style more consistently. Avoid some casts.
10025 Use 'double' consistently rather than mixing 'float' and 'double'.
10027 2012-04-21 Eduard Wiebe <usenet@pusto.de>
10029 * sysdep.c (list_system_processes, system_process_attributes):
10030 Add implementation for FreeBSD (Bug#5243).

10036 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
10038 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
10039 It is never used otherwise.
10041 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
10043 * print.c (print_preprocess): Only check print_depth if print-circle
10045 (print_object): Check for cycles even when print-circle is nil and
10046 print-gensym is t, but only check print_depth if print-circle is nil.
10048 2012-04-20 Chong Yidong <cyd@gnu.org>
10050 * process.c (wait_reading_process_output): If EIO occurs on a pty,
10051 set the status to "failed" and ensure that sentinel is run.
10053 2012-04-20 Glenn Morris <rgm@gnu.org>
10055 * process.c (Fset_process_inherit_coding_system_flag)
10056 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

10066 farther than the first row after the header line, if any.
10067 Don't consider the header-line row as "partially visible", even if
10068 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
10070 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

10108 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
10109 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10110 (NEED_MEM_INSERT): New macro.
10111 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10112 Remove one incorrect comment and fix another.

10121 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
10122 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
10123 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
10124 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
10125 [REL_ALLOC]: ... to here, to check interface.
10126 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
10127 Remove decls. This fixes an "It stinks!".
10129 * alloc.c (which_symbols): Fix alignment issue / type clash.
10131 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
10133 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

10148 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10149 * s/netbsd.h, s/sol2-6.h:
10150 Remove definition of GC_MARK_STACK, since the default now works.
10151 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
10152 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
10153 no longer the default.
10154 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
10156 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
10158 * lread.c (lisp_file_lexically_bound_p):

10177 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
10179 2012-04-11 Daniel Colascione <dancol@dancol.org>
10181 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10182 against is gone. It's better to use vfork now so that when Cygwin
10183 gains a new, working vfork, we use it automatically (bug#10398).
10185 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10200 (force_quit_count): New var.
10201 (handle_interrupt): Use it.
10203 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
10205 * w32.c (w32_delayed_load): Record the full path of the library
10206 being loaded (bug#10424).
10208 2012-04-09 Glenn Morris <rgm@gnu.org>
10210 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
10211 not just in the obarray, before snarfing them. (Bug#11036)
10213 * Makefile.in ($(leimdir)/leim-list.el):
10214 Pass EMACS rather than BUILT_EMACS.
10216 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
10218 * process.c (make_process):
10219 * process.h: Add integer `gnutls_handshakes_tried' member to
10222 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
10223 Add convenience `GNUTLS_LOG2i' macro.
10225 * gnutls.c (gnutls_log_function2i): Convenience log function.
10226 (emacs_gnutls_read): Use new log functions,
10227 `gnutls_handshakes_tried' process member, and
10228 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10229 attempts per process (connection).
10231 2012-04-09 Chong Yidong <cyd@gnu.org>
10233 * eval.c (Fuser_variable_p, user_variable_p_eh)

10238 * minibuf.c (Fread_variable): Callers changed.
10240 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10242 * xdisp.c (set_cursor_from_row): If the display string appears in
10243 the buffer at position that is closer to point than the position
10244 after the display string, display the cursor on the first glyph of
10245 the display string. Fixes cursor display when a 'display' text
10246 property immediately follows invisible text. (Bug#11094)
10248 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10250 composite.c: use 'double' consistently
10251 * composite.c (get_composition_id): Use 'double' consistently
10252 instead of converting 'float' to 'double' and vice versa; this is
10253 easier to understand and avoids a GCC warning.
10255 2012-04-09 Glenn Morris <rgm@gnu.org>
10257 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10258 preparation for dumping it with emacs. (Bug#4789)
10259 (leimdir): New variable.
10260 ($(leimdir)/leim-list.el): New rule.
10261 (emacs$(EXEEXT)): Depend on leim-list.el.

10277 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
10279 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
10280 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10281 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10282 objects, as mark_maybe_pointer will catch them otherwise.
10283 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
10284 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

10288 Fix typo that broke non-Windows builds.
10289 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
10291 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10293 Support building on MS-Windows with libxml2.
10295 * makefile.w32-in (OBJ2): Add xml.$(O).
10296 (GLOBAL_SOURCES): Add xml.c.
10297 ($(BLD)/xml.$(O)): New dependency list.
10299 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10300 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10301 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10302 [!WINDOWSNT]: New macros.
10303 (init_libxml2_functions, libxml2_loaded_p): New functions.
10304 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10305 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10306 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10307 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10309 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10310 Call init_libxml2_functions before calling libxml2 functions.
10311 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10313 * emacs.c: Don't include libxml/parser.h.
10314 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10315 xmlCleanupParser directly.
10317 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10319 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10321 * indent.c (Fvertical_motion): If there is a display string at
10322 point, use it.vpos to compute how many lines to backtrack after
10323 move_it_to point. (Bug#11133)
10325 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10327 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10328 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10329 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10330 macros related to unification of CJK characters. For the details,
10331 see the discussion following the message here:
10332 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10334 2012-04-04 Chong Yidong <cyd@gnu.org>
10336 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10338 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10340 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
10341 instead of alloca. (Bug#11138)
10343 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
10345 * w32menu.c (is_simple_dialog): Properly check lisp types.
10348 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10350 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10351 position we get to after a call to move_it_to fails the
10352 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10353 only if we wind up in a string from display property. (Bug#11063)
10355 * window.c (Fdelete_other_windows_internal): Invalidate the row
10356 and column information about mouse highlight, so that redisplay
10357 restores it after reallocating the glyph matrices. (Bug#7464)
10359 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10360 string comes from a `display' text property, use the buffer
10361 position of that property as if we actually saw that position in
10363 (move_it_by_lines): Remove the assertion that
10364 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10365 violated when there's a before-string at the beginning of a line.
10368 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10370 * xdisp.c (append_space_for_newline): If the default face was
10371 remapped, use the remapped face for the appended newline.
10372 (extend_face_to_end_of_line): Use the remapped default face for
10373 extending the face to the end of the line.
10374 (display_line): Call extend_face_to_end_of_line when the default
10375 face was remapped. (Bug#11068)
10377 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10379 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
10381 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
10383 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
10385 2012-03-27 Glenn Morris <rgm@gnu.org>
10387 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
10390 2012-03-26 Kenichi Handa <handa@m17n.org>
10392 * dispextern.h (struct glyph): Fix previous change. Change the
10393 bit length of glyphless.ch to 25 (Bug#11082).
10395 2012-03-26 Chong Yidong <cyd@gnu.org>
10397 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10398 (command_loop_1): Use it; inhibit selection update for
10399 handle-select-window too (Bug#8996).
10401 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
10403 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10405 2012-03-25 Kenichi Handa <handa@m17n.org>
10407 * dispextern.h (struct glyph): Change the bit length of
10408 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10410 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10412 * s/ms-w32.h (tzname): Include time.h before redirecting to
10413 _tzname. Fixes the MSVC build. (Bug#9960)
10415 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
10417 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10420 * xterm.c (XTread_socket): Only modify handling_signal if
10421 !SYNC_INPUT. (Bug#11080)
10423 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10425 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10426 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10427 when fetching a multibyte character consumes more bytes than
10428 CHAR_BYTES returns, due to unification of CJK characters in
10429 string_char. (Bug#11073)
10431 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10433 * process.c (wait_reading_process_output): Handle pty disconnect
10434 by refraining from sending oneself a SIGCHLD (bug#10933).
10436 2012-03-22 Chong Yidong <cyd@gnu.org>

10441 Mark string as coming from a prefix property.
10442 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10443 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10445 2012-03-21 Chong Yidong <cyd@gnu.org>
10447 * xfaces.c (Vface_remapping_alist): Doc fix.
10449 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10451 * w32proc.c (Fw32_set_console_codepage)
10452 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
10455 2012-03-20 Chong Yidong <cyd@gnu.org>
10457 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10458 to reflect default non-nil value of redisplay-dont-pause.
10460 2012-03-19 Kenichi Handa <handa@m17n.org>
10462 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10463 it fit in a valid range (Bug#11003).
10465 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10467 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10468 that is not from display property, accept the row as a "cursor
10469 row" if one of the string's character has a non-nil `cursor'
10470 property. Fixes cursor positioning when there are newlines in
10471 overlay strings, e.g. in icomplete.el. (Bug#11035)
10473 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10475 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10477 2012-03-12 Chong Yidong <cyd@gnu.org>
10479 * eval.c (inhibit_lisp_code): Rename from
10480 inhibit_window_configuration_change_hook; move from window.c.
10482 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10483 * window.c (run_window_configuration_change_hook)
10484 (syms_of_window): Callers changed.
10486 2012-03-11 Chong Yidong <cyd@gnu.org>
10488 * keymap.c (Fkey_description): Doc fix (Bug#9700).
10490 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10492 2012-03-10 Chong Yidong <cyd@gnu.org>
10494 * frame.c (other_visible_frames): Don't assume the selected frame
10495 is visible (Bug#10955).
10497 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10499 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
10501 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
10503 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10504 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10507 2012-03-03 Glenn Morris <rgm@gnu.org>
10509 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10511 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10513 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10514 position past the first glyph_row that ends at ZV. (Bug#10902)
10515 (redisplay_window, next_element_from_string): Fix typos in
10517 (redisplay_window): Pass to move_it_vertically the margin in
10518 pixels, not in screen lines.
10520 2012-03-02 Glenn Morris <rgm@gnu.org>
10522 * buffer.c (buffer-list-update-hook): Doc fix.
10524 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10526 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10527 push_it before setting up the iterator for the first overlay
10528 string, even if we have an empty string loaded.
10529 (next_overlay_string): If there's an empty string on the iterator
10530 stack, pop the stack. (Bug#10903)
10532 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10534 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10535 Suggested by Stefan Monnier in
10536 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10537 * alloc.c (widen_to_Lisp_Object): New static function.
10538 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10539 and widening them to Lisp_Objects. This would work even if
10540 USE_LSB_TAG is defined and wide integers are used, which might
10541 happen in a future version of Emacs.
10543 2012-02-25 Chong Yidong <cyd@gnu.org>
10545 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10548 * xselect.c (Fx_selection_exists_p): Doc fix.
10549 (x_clipboard_manager_save_all): Print an informative message
10550 before saving to clipboard manager.
10552 2012-02-24 Chong Yidong <cyd@gnu.org>
10554 * keyboard.c (process_special_events): Handle all X selection
10555 requests in kbd_buffer, not just the next one (Bug#8869).
10557 2012-02-23 Chong Yidong <cyd@gnu.org>
10559 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10560 call when setting menu-bar-lines and tool-bar-lines parameters.
10561 (unwind_create_frame_1): New helper function.
10563 * window.c (inhibit_window_configuration_change_hook): New var.
10564 (run_window_configuration_change_hook): Obey it.

10582 when computing $valmask.
10584 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10585 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10586 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10587 It's useless in that case, and it can cause problems on hosts
10588 that allocate halves of EMACS_INT values separately.
10589 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10590 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10591 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10592 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10593 it avoids undefined behavior on hosts where shifting right by more
10594 than the word width has undefined behavior.
10596 2012-02-19 Chong Yidong <cyd@gnu.org>
10598 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10599 (Funhandled_file_name_directory, Ffile_name_as_directory)
10600 (Fdirectory_file_name, Fexpand_file_name)
10601 (Fsubstitute_in_file_name): Protect against invalid file handler
10602 return values (Bug#10845).
10604 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10606 * .gdbinit (pitx): Fix incorrect references to fields of the

10613 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
10615 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
10616 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10618 2012-02-15 Chong Yidong <cyd@gnu.org>
10620 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10621 marked as special. Also, starting docstrings with * is obsolete.
10623 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
10625 * gnutls.c (emacs_gnutls_write): Fix last change.

10636 2012-02-12 Chong Yidong <cyd@gnu.org>
10638 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10639 as that creates a dangerous corner case.
10641 * window.c (Fdelete_window_internal): Invalidate the mouse
10642 highlight (Bug#9904).
10644 2012-02-12 Glenn Morris <rgm@gnu.org>
10646 * xselect.c (Fx_own_selection_internal)
10647 (Fx_get_selection_internal, Fx_disown_selection_internal)
10648 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
10649 * nsselect.m (Fx_own_selection_internal)
10650 (Fx_disown_selection_internal, Fx_selection_exists_p)
10651 (Fx_selection_owner_p, Fx_get_selection_internal):
10652 Sync docs and argument specs with the xselect.c versions.
10654 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
10656 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
10658 2012-02-11 Eli Zaretskii <eliz@gnu.org>
10660 * w32select.c (Fx_selection_exists_p): Sync doc string and
10661 argument list with xselect.c. (Bug#10783)
10663 * w16select.c (Fx_selection_exists_p): Sync doc string and

11211 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
11212 verifies glyph row's hash code--we have just reallocated the
11213 glyphs, so their contents can be complete garbage. (Bug#10164)

11377 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
11378 is set, removing the need for VIRT_ADDRESS_VARIES.
11379 (PURE_P): Use a more-efficient implementation that needs just one
11380 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
11381 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
11382 to 4 (xorl, subq, cmpq, setbe).
11383 * alloc.c (pure): Always extern now, since that's the

11386 consistency with the new puresize.h.
11387 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
11388 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

11394 (erase_phys_cursor, update_window_cursor, show_mouse_face)
11395 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
11396 behave as if the cursor position were at the window margin.
11398 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11399 and the cursor position is out of bounds, behave as if the cursor
11400 position were at the window margin. (Bug#10075)
11402 2011-11-18 Chong Yidong <cyd@gnu.org>
11404 * window.c (Fwindow_combination_limit): Make first argument

11423 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
11425 * xdisp.c (row_hash): New function, body extracted from
11426 compute_line_metrics.
11427 (compute_line_metrics): Call row_hash, instead of computing the
11430 * dispnew.c (verify_row_hash): Call row_hash for computing the
11431 hash code of a row, instead of duplicating code from xdisp.c.
11433 * dispextern.h (row_hash): Add prototype.
11435 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11437 * frame.c (delete_frame): Don't delete the terminal when the last

11473 * xdisp.c (display_line): Move the call to
11474 highlight_trailing_whitespace before the call to
11475 compute_line_metrics, since the latter needs to see the final
11476 faces of all the glyphs to compute ROW's hash value.

11486 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11487 with user-defined heap size. Bump the default size of the temacs

11491 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11492 current_matrix and desired_matrix. (Bug#9990)
11493 (verify_row_hash) [XASSERTS]: New function.

11618 (window_box_width, window_box_left, window_box_left_offset)
11619 (window_box_right, window_box_right_offset): Declare extern.
11620 Otherwise, these inline functions do not conform to C99 and
11621 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11622 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11623 * intervals.c (adjust_intervals_for_insertion)
11624 (adjust_intervals_for_deletion): Now extern, because otherwise the
11625 extern inline functions 'offset_intervals' couldn't refer to it.
11626 (static_offset_intervals): Remove.
11627 (offset_intervals): Rewrite using the old contents of
11628 static_offset_intervals. The old version didn't conform to C99
11629 because an extern inline function contained a reference to an
11630 identifier with static linkage.
11632 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
11634 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

11652 (Fwindow_vscroll): Doc fix.
11653 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
11654 argument, since it makes no sense to pass a live window and for
11655 consistency with window-child.

11683 (unwind_create_frame): New function (Bug#9943).
11684 (Fx_create_frame): Restructure code to be more similar to the one in
11685 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

11696 official. Move initialization of image_cache_refcount and
11697 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

11737 previous/next-single-property-change returns nil, treat that as
11738 the beginning or the end of the buffer. (Bug#9955)
11740 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
11742 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

11802 so that this new function doesn't get optimized away by a

11830 2011-10-28 Eli Zaretskii <eliz@gnu.org>

11865 (w32font_open_internal, compute_metrics):
11866 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11867 instead of calling the "wide" APIs directly.

11871 * w32.h (syms_of_w32font): Add prototype.

11877 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
11878 (Fmove_to_window_line): Doc fix.
11880 2011-10-27 Chong Yidong <cyd@gnu.org>
11882 * process.c (make_process): Set gnutls_state to NULL.
11884 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11885 non-NULL, regardless of GNUTLS_INITSTAGE.
11886 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

11913 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
11915 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).

11934 (bidi_resolve_weak): Don't enter the expensive loop if the current
11935 position is before next_en_pos. Record the bidi type of the first
11936 non-ET, non-BN character we find, in addition to its position.
11937 (bidi_level_of_next_char): Invalidate next_en_type when
11938 next_en_pos is over-stepped.
11940 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11942 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11943 * editfns.c: Rewrite current-time-zone so that it invokes
11944 the equivalent of (format-time-string "%Z") to get the time zone name.
11945 This fixes a bug when the time zone name contains characters that
11946 need converting from the system time locale to Emacs internal format.
11947 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11948 that patch fixed format-time-string to do the conversion, but
11949 I forgot to fix current-time-zone.
11950 (format_time_string): New function, containing most of
11951 what Fformat_time_string used to contain.
11952 (Fformat_time_string): Rewrite in terms of format_time_string.
11953 This doesn't change this function's behavior.
11954 (current-time-zone): Rewrite to use format_time_string.
11955 This fixes the bug reported by Michael Schierl in
11956 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11957 Jason Rumney's 2007-06-07 change worked around this bug, but
11959 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11961 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11963 * xdisp.c (start_display): If the character at POS is displayed
11964 via a display vector, reset IT->current.dpvec_index to zero.
11965 (try_window_reusing_current_matrix): If a line ends in a display
11966 vector or the next line starts in a display vector, continue
11967 redrawing the window even though the character position of
11968 start_row was reached.
11971 2011-10-18 Chong Yidong <cyd@gnu.org>
11973 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11974 with nobreak-char-display too.
11976 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11978 Fix part 3 of bug#9771.
11979 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11980 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11981 non-neutral characters if the current character is a paragraph
11982 separator (a.k.a. Newline). This avoids running the same
11983 expensive loop twice, once when we consume the preceding newline
11984 and the other time when the line actually needs to be displayed.
11985 Avoid the loop when we see neutrals on the base embedding level
11986 following a character whose directionality is the same as the
11987 paragraph's. This avoids running the expensive loop when a line
11988 ends in a long sequence of neutrals, like control characters.
11989 Add assertion against STRONG_AL type. Slightly rearrange code
11990 that determines the type of a neutral given the first non-neutral
11992 (bidi_level_of_next_char): Set next_en_pos to zero when
11993 invalidating its info.
11995 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11997 * xdisp.c (push_display_prop): Determine whether to record string
11998 or buffer position by IT->string, not by IT->method. Allow
11999 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12000 (move_it_vertically_backward): Don't look for character position
12001 immediately after the newline when in a continuation line.
12004 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12006 * window.c (coordinates_in_window): Rewrite and delabelize
12007 vertical border check. (Bug#5357) (Bug#9618)
12009 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12011 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12012 errors in XSetWindowBorder (bug#9310).
12014 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12016 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12017 avoid crash when xmalloc overrun checking is enabled.
12019 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12021 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12022 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12023 cursor motion with <left> and <right> arrow keys.
12025 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12026 some callers set that themselves.
12028 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12030 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12031 display string and the previous row comes from the same string and
12032 is empty. (Bug#9739) (Bug#9738)
12034 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12036 * doc.c (get_doc_string): Encode file name (bug#9735).
12038 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12040 * bidi.c (bidi_level_of_next_char):
12041 * xdisp.c (get_visually_first_element): Remove old incorrect
12042 comments regarding the Unicode Line Separator character.
12044 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12046 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

12049 boundary if nzombies > MAX_ZOMBIES.
12050 * alloc.c (dump_zombies): Add missing format specifier.
12052 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12054 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12055 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12057 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12058 Some packages use them to denote characters with modifiers.
12060 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12062 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12063 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12064 matching a pp-number. Rename parameter var to var1.
12066 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12068 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12070 2011-10-08 Glenn Morris <rgm@gnu.org>
12072 * callint.c (Fcall_interactively): Give a more explicit error for the
12073 'c' case with a non-character input. (Bug#8479)
12075 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12077 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12079 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12080 lines that are hscrolled on the left.
12082 * dispnew.c (buffer_posn_from_coords): Account for a possible
12083 presence of header-line. (Bug#4426)
12085 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12087 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12088 Don't advertise functionality which we discourage or doesn't work.
12090 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12092 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12093 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12094 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12095 this makes Emacs dump core during garbage collection on rare
12096 occasions. sizeof is obviously inferior to offsetof here, so
12097 stick with offsetof.
12098 (GC_POINTER_ALIGNMENT): New macro.
12099 (mark_memory): Omit 3rd (offset) arg; caller changed.
12100 Don't assume EMACS_INT alignment is the same as pointer alignment.
12102 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12104 * keyboard.c (read_key_sequence_remapped): New var.
12105 (read_key_sequence): Compute remapping in the right buffer.
12106 (command_loop_1): Use read_key_sequence's remapping directly.
12108 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12110 * dired.c (file_name_completion): Don't expand file name.
12111 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12112 before checking file name handler.
12114 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12115 they've been requested explicitly (bug#9591).
12117 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12119 * keymap.c (Fsingle_key_description): Use make_specified_string
12120 instead of build_string to build string from push_key_description.
12123 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12125 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12126 This fixes a Y2038 bug on 64-bit hosts.
12127 * buffer.c (reset_buffer):
12128 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12129 (Fclear_buffer_auto_save_failure):
12130 Use 0, not -1, to represent an unset failure time, since time_t
12131 might not be signed.
12133 Remove dependency on glibc malloc internals.
12134 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12135 Move back here from lisp.h, but with their new implementations.
12136 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12137 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12138 * charset.c (charset_table_init): New static var.
12139 (syms_of_charset): Use it instead of xmalloc. This removes a
12140 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12141 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12142 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12143 Move back to alloc.c.
12144 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12145 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12147 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12149 * nsterm.m (windowDidResize): Call x_set_window_size only when
12150 ns_in_resize is true. Otherwise set pixelwidth/height and
12151 call change_frame_size (Bug#9628).
12153 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12155 Port --enable-checking=all to Fedora 14 x86-64.
12156 * charset.c (syms_of_charset): Also account for glibc malloc's
12157 internal overhead when calculating the initial malloc maximum.
12159 Port --enable-checking=all to Fedora 14 x86.
12160 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12162 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12163 (overrun_check_realloc, overrun_check_free):
12164 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12165 That way, xmalloc returns a properly-aligned pointer even if
12166 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12167 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12168 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12169 into account when calculating the initial malloc maximum.
12170 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12171 Move here from alloc.c, so that charset.c can use it too.
12172 Properly align; the old code wasn't right for common 32-bit hosts
12173 when configured with --enable-checking=all.
12174 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12175 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12177 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12179 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12182 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12184 * xdisp.c (compute_display_string_end): If there's no display
12185 string at CHARPOS, return -1.
12187 * bidi.c (bidi_fetch_char): When compute_display_string_end
12188 returns a negative value, treat the character as a normal
12189 character not covered by a display string. (Bug#9624)
12191 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12193 * lread.c (Fread_from_string): Fix typo in docstring.
12195 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12197 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12198 newline, reseat the iterator instead of bidi-iterating there one
12199 character at a time. (Bug#9610)
12200 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12201 TO_CHARPOS if the bidi iterator is at base embedding level.
12203 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12205 * lread.c (readevalloop): Use correct code for NBSP.
12206 (read1): Likewise. (Bug#9608)
12208 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12210 * dbusbind.c (Fdbus_register_signal): When service is not
12211 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12213 2011-09-25 Glenn Morris <rgm@gnu.org>
12215 * buffer.c (truncate-lines): Doc fix.
12217 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12219 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12220 (Fset_window_next_buffers): Doc fix.
12222 2011-09-24 Glenn Morris <rgm@gnu.org>
12224 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12226 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12228 Fix minor problems found by static checking.
12229 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12230 * indent.c (Fvertical_motion): Fix == vs = typo.
12232 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12234 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12235 Default value is now t. Doc fix.
12237 * indent.c (Fvertical_motion): Compute and apply the overshoot
12238 logic when moving up, not only when moving down. Fix the
12239 confusing name and values of the it_overshoot_expected variable;
12240 logic changes accordingly. (Bug#9254) (Bug#9549)
12242 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12243 CHARPOS is covered by a display string which includes newlines.
12244 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12245 is covered by a display string with embedded newlines.
12247 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12249 * dbusbind.c (Fdbus_register_signal): Add match rule to
12250 Vdbus_registered_objects_table. (Bug#9581)
12251 (Fdbus_register_method, Vdbus_registered_objects_table):
12254 2011-09-24 Jim Meyering <meyering@redhat.com>
12256 do not ignore write error for any output size
12257 The previous change was incomplete.
12258 While it makes emacs --batch detect the vast majority of stdout
12259 write failures, errors were still ignored whenever the output size is
12260 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12261 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12262 && echo FAIL: ignored write error
12263 FAIL: ignored write error
12264 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12265 && echo FAIL: ignored write error
12266 FAIL: ignored write error
12267 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12269 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12271 * emacs.c (Fkill_emacs): In noninteractive mode exit
12272 non-successfully if a write error occurred on stdout. (Bug#9574)
12274 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12276 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12279 * dispextern.h (struct it): Update the comment documenting what
12282 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12284 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12285 a display string, extend search for cursor position to end of row.
12286 (find_row_edges): If the row ends in a newline from a display
12287 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12288 Handle the case of a display string with multiple newlines.
12289 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12290 non-empty line. Fixes confusing cursor motion with arrow keys at
12291 the beginning of a line that starts with whitespace.
12293 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12295 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12298 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12300 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12301 boolean (Bug#9154).
12303 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12305 * xdisp.c (display_line): Record maximum and minimum buffer
12306 positions even if no glyphs were produced (e.g., by a zero-width
12307 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12308 buffer positions that will be removed from the glyph row because
12310 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12311 column is beyond frame width: don't subtract 1 "pixel" when
12312 computing width of the stretch.
12313 (reseat_at_next_visible_line_start): Undo the change made on
12314 2011-09-17 that saved paragraph information and restored it after
12315 the call to `reseat'. (Bug#9545)
12317 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12319 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12320 and turn window cursor on if cleared (Bug#9415).
12322 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12324 * search.c (boyer_moore): Take unibyte characters from pattern
12325 literally. (Bug#9458)
12327 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12329 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12331 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12333 Fix minor problem found by static checking.
12334 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12335 initialized, to pacify gcc -Wuninitialized.
12337 * fileio.c: Report proper errno when syscall falls.
12338 (Finsert_file_contents): Save and restore errno,
12339 so that report_file_error outputs the correct diagnostic.
12340 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12342 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12344 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12346 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12348 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12349 2011-08-30 (revision 105619). (Bug#9530)
12351 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12353 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12354 about the current paragraph and restore it after the call to reseat.
12356 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12357 (bidi_find_paragraph_start): Search back for paragraph beginning
12358 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12359 (bidi_move_to_visually_next): Only trigger paragraph-related
12360 computations when the last character is a newline or at EOB, not
12361 just any NEUTRAL_B. (Bug#9470)
12363 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12364 truncated lines if point is covered by a display string. (Bug#9524)
12366 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12368 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12369 (cons_to_x_long): New function.
12370 (lisp_data_to_selection_data): Use it. Correct the test for
12371 short-versus-long data; it was negated. Break out of vector
12372 loop, for efficiency, when a long datum is discovered.
12374 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12376 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12378 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12380 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12381 GCC PR/17406) by declaring this function with external scope.
12383 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12385 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12386 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12388 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12390 * editfns.c (Fformat): Correctly handle text properties on "%%".
12392 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12394 * xterm.c (x_draw_composite_glyph_string_foreground):
12395 * w32term.c (x_draw_composite_glyph_string_foreground):
12396 * term.c (encode_terminal_code):
12397 * composite.c (composition_update_it, get_composition_id):
12398 * xdisp.c (get_next_display_element)
12399 (fill_composite_glyph_string): Add comments about special meaning
12400 of TAB characters in a composition.
12402 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12404 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12405 This occurs when processing a multibyte format.
12406 Problem reported by Wolfgang Jenker.
12408 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12410 * xdisp.c (try_cursor_movement): Only check for exact match if
12411 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12413 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12415 Remove unused external symbols.
12416 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12417 * xdisp.c (calc_pixel_width_or_height): Now static.
12418 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12419 * indent.c (check_display_width):
12420 * w32term.c: Fix comment to match code.
12421 * xterm.c, xterm.h (x_catching_errors): Remove.
12423 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12425 * xselect.c: Use signed conversions more consistently (Bug#9498).
12426 (selection_data_to_lisp_data): Assume incoming selection data are
12427 signed integers, not unsigned. This is to be consistent with
12428 outgoing selection data, which was modified to use signed integers
12429 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12430 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12431 expects long, not unsigned long.
12433 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12435 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12436 computation of loop end. Reported by Johan Bockgård
12439 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12441 * frame.c (Fother_visible_frames_p): Function deleted.
12443 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12445 * indent.c (compute_motion): Process display vector front to back
12446 rather than the other way around. (Bug#2496)
12448 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12450 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12452 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12454 * minibuf.c (Fread_from_minibuffer): Doc fix.
12456 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12458 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12459 2011-08-30 (revision 105619). (Bug#9475)
12461 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12463 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12464 value for non-existent files.
12466 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12468 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12469 set its "size" to -1. This will set the modtime_size field of
12470 the corresponding buffer to -1, which is what
12471 verify-visited-file-modtime expects for files that do not exist.
12474 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12476 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12478 * lisp.h: ... from here. push_key_description is no longer
12479 defined in keyboard.c, so its declaration should not be in
12480 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12481 logically belongs with push_key_description.
12483 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12485 * buffer.h: Include <sys/types.h> instead of <time.h>.
12486 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12487 Problem reported by Herbert J. Skuhra.
12489 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12491 * xml.c (parse_region): Make the parsing work for
12492 non-comment-starting XML files again (bug#9144).
12494 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12496 * image.c (gif_load): Fix calculation of bottom and right corner.
12499 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12501 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12502 redisplay in small windows.
12504 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12506 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12508 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12510 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12511 Operate on live windows only.
12513 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12515 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12517 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12519 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12520 only under bidi iteration.
12522 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12524 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.

12528 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12529 Without this fix, the command to link temacs failed due to an
12530 undefined symbol __builtin_isnan. This is because
12531 /usr/include/iso/math_c99.h #defines isnan(x) to
12532 __builtin_isnan(x), but the bundled gcc, which identifies itself
12533 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12535 * floatfns.c (isnan): #undef, and then #define to a clone of
12537 (Fisnan): Always define, since it's always available now.
12538 (syms_of_floatfns): Always define isnan at the Lisp level.
12540 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12542 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12544 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12546 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12547 The previous code assumed that file offsets (off_t values) fit in
12548 EMACS_INT variables, which is not true on typical 32-bit hosts.
12549 The code messed up by falsely reporting buffer overflow in cases
12550 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12551 when "big" contains more than 2**29 bytes, even though this
12552 inserts just one byte and does not overflow the buffer.
12553 (Finsert_file_contents): Store file offsets as off_t
12554 values, not as EMACS_INT values. Check for overflow when
12555 converting between EMACS_INT and off_t. When checking for
12556 buffer overflow or for overlap, take the offsets into account.
12557 Don't use EMACS_INT for small values where int suffices.
12558 When checking for overlap, fix a typo: ZV was used where
12559 ZV_BYTE was intended.
12560 (Fwrite_region): Don't assume off_t fits into 'long'.
12561 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12563 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12565 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12567 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12569 sprintf-related integer and memory overflow issues (Bug#9412).
12571 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12572 (esprintf, exprintf, evxprintf): New functions.
12573 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12574 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12575 (modify_event_symbol): Do not assume that the length of
12576 name_alist_or_stem is safe to alloca and fits in int.
12577 (Fexecute_extended_command): Likewise for function name and binding.
12578 (Frecursion_depth): Wrap around reliably on integer overflow.
12579 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12580 since some callers pass EMACS_INT values.
12581 (Fsingle_key_description): Don't crash if symbol name contains more
12582 than MAX_ALLOCA bytes.
12583 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12584 (get_minibuffer): Arg is now EMACS_INT, not int.
12585 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12586 (esprintf, exprintf, evxprintf): New decls.
12587 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12589 * dbusbind.c (signature_cat): New function.
12590 (xd_signature, Fdbus_register_signal):
12591 Do not overrun buffer; instead, report string overflow.
12593 * dispnew.c (add_window_display_history): Don't overrun buffer.
12594 Truncate instead; this is OK since it's just a log.
12596 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12597 even if the time zone offset is outlandishly large.
12598 Don't mishandle offset == INT_MIN.
12600 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12601 when creating daemon; the previous buffer-overflow check was incorrect.
12603 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12604 which has the guts of the old verror function.
12606 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12607 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12609 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12610 (font_unparse_xlfd): Don't blindly alloca long strings.
12611 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12612 fits in int, when using sprintf. Use single snprintf to count
12613 length of string rather than counting it via multiple sprintfs;
12614 that's simpler and more reliable.
12615 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12616 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12617 sprintf, in case result does not fit in int.
12619 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12620 (fontset_from_font): Print it.
12622 * frame.c (tty_frame_count): Now printmax_t, not int.
12623 (make_terminal_frame, set_term_frame_name): Print it.
12624 (x_report_frame_params): In X, window IDs are unsigned long,
12625 not signed long, so print them as unsigned.
12626 (validate_x_resource_name): Check for implausibly long names,
12627 and don't assume name length fits in 'int'.
12628 (x_get_resource_string): Don't blindly alloca invocation name;
12629 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12632 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12633 (xg_check_special_colors, xg_set_geometry):
12634 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12636 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12637 Use esprintf, not sprintf, in case result does not fit in int.
12639 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12640 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12641 it as a large positive number.
12642 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12643 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12645 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12646 in case result does not fit in int.
12648 * print.c (float_to_string): Detect width overflow more reliably.
12649 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12650 buffer overrun. Don't assume list length fits in 'int'. Treat
12651 print length of 0 as 0, not as infinity; to be consistent with other
12652 uses of print length in this function. Don't overflow print length
12653 index. Don't assume hash table size fits in 'long', or that
12654 vectorlike size fits in 'unsigned long'.
12656 * process.c (make_process): Use printmax_t, not int, to format
12657 process-name gensyms.
12659 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12661 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12662 to avoid potential buffer overrun.
12664 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12665 if X resource line is longer than 512 bytes.
12667 * xfns.c (x_window): Make sprintf buffer a bit bigger
12668 to avoid potential buffer overrun.
12670 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12672 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12674 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12676 Integer overflow fixes for scrolling, etc.
12677 Without these, Emacs silently mishandles large integers sometimes.
12678 For example, "C-u 4294967297 M-x recenter" was treated as if
12679 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12681 * xdisp.c (try_window_id): Check Emacs fixnum range before
12682 converting to 'int'.
12684 * window.c (window_scroll_line_based, Frecenter):
12685 Check that an Emacs fixnum is in range before assigning it to 'int'.
12686 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12687 values converted from Emacs fixnums.
12688 (Frecenter): Don't wrap around a line count if it is out of 'int'
12689 range; instead, treat it as an extreme value.
12690 (Fset_window_configuration, compare_window_configurations):
12691 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12693 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12694 that can exceed INT_MAX. Check that EMACS_INT value is in range
12695 before assigning it to the (possibly-narrower) index.
12696 (match_limit): Don't assume that a fixnum can fit in 'int'.
12698 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12701 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12702 (Fvertical_motion): Don't wrap around LINES values that don't fit
12703 in 'int'. Instead, treat them as extreme values. This is good
12704 enough for windows, which can't have more than INT_MAX lines anyway.
12706 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12708 * Require libxml/parser.h to avoid compilation warning.
12710 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12712 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12713 since this reportedly can destroy thread storage.
12715 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12717 * syntax.c (find_defun_start): Update all cache variables if
12718 exiting early (Bug#9401).
12720 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12722 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12724 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12725 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12726 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12728 * term.c (tty_append_glyph): New function.
12729 (produce_stretch_glyph): Static function and its prototype deleted.
12731 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12734 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12736 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12737 when checking :margin (Bug#9390).
12738 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12739 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12740 so that the name doesn't mislead. All uses changed.
12742 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12744 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12747 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12749 * xdisp.c (move_it_to): Don't bail out early when reaching
12750 position beyond to_charpos, if we are scanning backwards.
12751 (move_it_vertically_backward): When DY == 0, make sure we get to
12752 the first character in the line after the newline.
12754 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12756 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12757 (ccl_driver): Do not generate an out-of-range pointer.
12758 (Fccl_execute_on_string): Remove unnecessary check for
12759 integer overflow, noted by Stefan Monnier in
12760 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12761 Remove a FIXME that didn't need fixing.
12762 Simplify the newly-introduced buffer reallocation code.
12764 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12766 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12768 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12770 Integer and memory overflow issues (Bug#9196).
12772 * doc.c (get_doc_string): Rework so that
12773 get_doc_string_buffer_size is the actual buffer size, rather than
12774 being 1 less than the actual buffer size; this makes xpalloc more
12777 * image.c (x_allocate_bitmap_record, cache_image):
12778 * xselect.c (Fx_register_dnd_atom):
12779 Simplify previous changes by using xpalloc.
12781 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12782 since either will do and ptrdiff_t is convenient with xpalloc.
12784 * charset.c (charset_table_size)
12785 (struct charset_sort_data.priority): Now ptrdiff_t.
12786 (charset_compare): Don't overflow if priorities differ greatly.
12787 (Fsort_charsets): Don't assume list length fits in int.
12788 Check for size-calculation overflow when allocating sort data.
12789 (syms_of_charset): Allocate an initial charset table that is
12790 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12792 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12794 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12795 The actual value is always <= INT_MAX, and leaving it unsigned made
12796 overflow checking harder.
12798 * dispextern.h (struct glyph_matrix.rows_allocated)
12799 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12800 with xpalloc. The values are still always <= INT_MAX.
12802 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12804 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12805 (SAFE_NALLOCA): New macro.
12807 * region-cache.c (struct boundary.pos, find_cache_boundary)
12808 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12809 (set_cache_region, invalidate_region_cache)
12810 (revalidate_region_cache, know_region_cache, region_cache_forward)
12811 (region_cache_backward, pp_cache):
12812 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12813 so that ptrdiff_t * can be passed to xpalloc.
12814 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12815 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12816 (pp_cache): Don't assume cache_len fits in int.
12817 * region-cache.h: Adjust extern decls to match.
12819 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12820 EMACS_INT, since either will do, for xpalloc.
12822 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12823 (xnmalloc, xnrealloc, xpalloc): New functions.
12825 * bidi.c (bidi_shelve_header_size): New constant.
12826 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12827 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12829 * bidi.c (bidi_cache_shrink):
12830 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12832 Don't update size of array until after memory allocation succeeds,
12833 because xmalloc/xrealloc may not return.
12834 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12835 now that we have proper integer overflow checking.
12836 (record_overlay_string, overlay_strings): Catch overflows when
12837 calculating size of overlay_str_buf.
12839 * callproc.c (Fcall_process): Check for size overflow when
12840 calculating size of args2.
12841 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12842 Normally we prefer signed values, but sticking with ptrdiff_t would
12843 require adding more-complicated checks.
12845 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12846 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12847 Redo buffer-overflow calculations to avoid integer overflow.
12848 Add a FIXME comment where memory seems to be over-allocated.
12850 * character.c (Fstring): Check for size-calculation overflow.
12852 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12853 unnecessary integer overflow. Check for size overflow.
12854 (encode_coding_object): Don't update size until xmalloc succeeds.
12856 * composite.c (get_composition_id): Check for overflow in glyph
12857 length calculations.
12859 Integer and memory overflow fixes for display code.
12860 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12861 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12862 (scrolling_window): Check for overflow in size calculations.
12863 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12864 Don't assume glyph table len fits in int.

12866 (row_table_size): Now ptrdiff_t, not int.
12867 (scrolling_window): Avoid overflow in size calculations.
12868 Don't update size until allocation succeeds.
12869 * fns.c (concat): Check for overflow in size calculations.
12870 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12871 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
12872 (NEXT_ALMOST_PRIME_LIMIT): New constant.
12874 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12875 (get_doc_string): Check for size calculation overflow.
12876 Don't update size until allocation succeeds.
12877 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12878 EMACS_INT, where ptrdiff_t will do.
12879 (Fsubstitute_command_keys): Check for string overflow.
12881 * editfns.c (set_time_zone_rule): Don't assume environment length
12883 (message_length): Now ptrdiff_t, not int.
12884 (Fmessage_box): Don't update size until allocation succeeds.
12885 Don't assume message length fits in int.
12886 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12888 * emacs.c (main): Do not reallocate argv, since there is a null at
12889 the end that can be overwritten, and this way there's no need to
12890 worry about size-calculation overflow.
12891 (sort_args): Check for size-calculation overflow.
12893 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12895 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12897 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12898 (x_set_scroll_bar_width, x_figure_window_size):
12899 Check for integer overflow.
12900 (x_set_alpha): Do not assume XINT fits in int.
12902 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12903 This is for the members text_lines, text_cols, total_lines, total_cols,
12904 where the system imposes an 'int' limit.
12906 * fringe.c (Fdefine_fringe_bitmap):
12907 Don't update size until alloc works.
12909 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12910 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12912 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12913 Check for size-calculation overflow.
12914 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12915 do, as we prefer signed integers.
12916 (id_to_widget.max_size, id_to_widget.used)
12917 (xg_store_widget_in_map, xg_remove_widget_from_map)
12918 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12919 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12920 Use and return ptrdiff_t, not int.
12921 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12922 * gtkutil.h: Change prototypes to match the above.
12924 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12925 are duplicate now that they've been promoted to lisp.h.
12926 (x_allocate_bitmap_record, x_alloc_image_color)
12927 (make_image_cache, cache_image, xpm_load):
12928 Don't update size until alloc is done.
12929 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
12931 Check for size calculation overflow.
12932 (ct_colors_allocated_max): New constant.
12933 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
12936 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
12937 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
12938 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12939 Use ptrdiff_t, not int, to count maps.
12940 (read_char_minibuf_menu_prompt): Check for overflow in size
12941 calculations. Don't update size until allocation succeeds.
12942 Redo calculations to avoid overflow.
12943 * keyboard.h: Change prototypes to match the above.
12945 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
12947 (current_minor_maps): Check for size calculation overflow.
12948 * keymap.h: Change prototypes to match the above.
12950 * lread.c (read1, init_obarray): Don't update size until alloc done.
12952 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
12953 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
12955 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
12956 Now ptrdiff_t, not int.
12957 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
12958 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
12960 * process.c (Fnetwork_interface_list): Check for overflow
12961 in size calculation.
12963 * region-cache.c (move_cache_gap): Check for size calculation overflow.
12965 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
12966 overflow. Don't bother calling xmalloc when xrealloc will do.
12968 * search.c (Freplace_match): Check for size calculation overflow.
12969 (Fset_match_data): Don't assume list lengths fit in 'int'.
12971 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12972 for command line length. Do not attempt to address one before the
12973 beginning of an array, as that's not portable.
12975 * term.c (max_frame_lines): Remove; unused.
12976 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12978 (encode_terminal_code, calculate_costs): Check for size
12979 calculation overflow.

12981 table lengths and related sizes. Don't update size until alloc
12982 done. Redo calculations to avoid overflow.
12983 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
12985 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
12986 subtracting pointers.
12987 (gobble_line): Check for overflow more carefully. Don't update size
12990 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
12991 Don't update size until alloc done.
12992 Redo size calculations to avoid overflow.
12993 Check for size calculation overflow.
12994 (main) [DEBUG]: Fix typo in invoking tparam1.

13001 Use ptrdiff_t, not int, for sizes.
13002 (Finternal_make_lisp_face, cache_face):
13003 Check for size calculation overflow.
13004 (cache_face): Treat size calculation overflows as if they were
13005 memory exhaustion (the usual treatment), rather than aborting.
13007 * xfns.c (x_encode_text, x_set_name_internal)
13008 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13009 sizes, since they can exceed INT_MAX in size. Check for size
13010 calculation overflow.
13012 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
13013 (xg_select): Check for size calculation overflow.
13014 Don't update size until alloc done.
13016 * xrdb.c (get_environ_db): Don't assume path length fits in int,
13017 as sprintf is limited to int lengths.
13019 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13020 (X_LONG_MIN): New macros.
13021 Use them to make the following changes clearer.
13022 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13023 This change doesn't affect the value now, but it may help remind
13024 future maintainers not to raise the value too much later.
13025 (SELECTION_QUANTUM): Remove, replacing with ...
13026 (selection_quantum): ... new function, which avoids overflow.
13028 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13029 assumption that selection length fits in 'int'.
13030 (x_reply_selection_request, x_handle_selection_request)
13031 (x_get_window_property, receive_incremental_selection)
13032 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
13033 (lisp_data_to_selection_data, clean_local_selection_data):

13035 (x_reply_selection_request, x_get_window_property)
13036 (receive_incremental_selection, x_property_data_to_lisp):
13037 Redo calculations to avoid overflow.
13038 (x_reply_selection_request): When sending hint, ceiling it at
13039 X_LONG_MAX rather than relying on wraparound overflow to send
13041 (x_get_window_property, receive_incremental_selection)
13042 (lisp_data_to_selection_data, x_property_data_to_lisp):
13043 Check for size-calculation overflow.
13044 (x_get_window_property, receive_incremental_selection)

13046 Don't store size until memory allocation succeeds.
13047 (x_get_window_property): Plug memory leak on memory exhaustion.
13048 Don't double-block input; malloc is safe here. Don't assume 2**34
13049 - 4 fits in unsigned long. Add an xassert to check
13050 XGetWindowProperty overflow. Be more careful about overflow
13051 calculations, and distinguish size from memory overflow better.
13052 (receive_incremental_selection): When tracing, don't assume
13053 unsigned int is less than INT_MAX.
13054 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
13055 harmful) conversions of unsigned short to int.
13056 (lisp_data_to_selection_data): Don't assume that integers
13057 in the range -65535 through -1 fit in an X unsigned short.
13058 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13059 result parameters unless successful. Rely on cons_to_unsigned
13060 to report problems with elements; the old code wasn't right anyway.
13061 (x_check_property_data): Check for int overflow; we cannot use
13062 a wider type due to X limits.
13063 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
13065 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
13067 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
13068 (x_term_init): Check for size calculation overflow.
13069 (x_color_cells): Don't store size until memory allocation succeeds.
13070 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
13071 Don't assume alloca size is less than MAX_ALLOCA.
13072 (x_term_init): Don't assume length fits in int (sprintf is limited

13094 * image.c (xpm_get_color_table_h):
13095 * lisp.h (hash_lookup, hash_put):
13096 * minibuf.c (Ftest_completion):
13097 Use ptrdiff_t for hash table indexes, not int (which is too
13098 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
13099 32-bit --with-wide-int hosts).
13101 * charset.c (Fdefine_charset_internal): Check for integer overflow.
13102 Add a FIXME comment about memory leaks.
13103 (syms_of_charset): Don't assume xmalloc returns.

13110 with outlandish widths.
13111 * character.h (sanitize_tab_width): Rename from sanitize_width,
13112 now that we have two such functions. All uses changed.

13124 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
13126 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
13127 Remove unreachable code.

13130 * xterm.c: Don't go over XClientMessageEvent limit.
13131 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
13132 (x_send_scroll_bar_event): Likewise. Check that the size does not
13133 exceed limits imposed by XClientMessageEvent, as well as the usual
13134 ptrdiff_t and size_t limits.
13136 * keyboard.c: Overflow, signedness and related fixes.
13137 (make_lispy_movement): Use same integer type in forward decl
13138 that is used in the definition.
13139 (read_key_sequence, keyremap_step):
13140 Change bufsize argument back to int, undoing my 2011-03-30 change.
13141 We prefer signed types, and int is wide enough here.
13142 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13143 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13144 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13145 length, not size_t. Use ptrdiff_t for index, not int.
13146 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13147 possibility of integer overflow.
13149 Overflow, signedness and related fixes for images.
13151 * dispextern.h (struct it.stack[0].u.image.image_id)

13159 * xdisp.c (calc_pixel_width_or_height):
13160 * xfns.c (image_cache_refcount):

13169 (image_ascent): Redo ascent calculation to avoid int overflow.
13170 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
13171 (lookup_image): Remove unnecessary tests.
13172 (xbm_image_p): Locals are now of int, not EMACS_INT,
13173 since parse_image_check makes sure they fit into int.
13174 (png_load, gif_load, svg_load_image):
13175 Prefer int to unsigned where either will do.
13176 (tiff_handler): New function, combining the cores of the
13177 old tiff_error_handler and tiff_warning_handler.
13178 This function is rewritten to use vsnprintf and thereby avoid
13179 stack buffer overflows. It uses only the features of vsnprintf
13180 that are common to both POSIX and native Microsoft.
13181 (tiff_error_handler, tiff_warning_handler): Use it.
13182 (tiff_load, gif_load, imagemagick_load_image):
13183 Don't assume :index value fits in 'int'.
13184 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
13185 (imagemagick_load_image): Check that crop parameters fit into
13186 the integer types that MagickCropImage accepts. Don't assume
13187 Vimagemagick_render_type has a nonnegative value. Don't assume
13188 size_t fits in 'long'.
13189 (gs_load): Use printmax_t to print the widest integers possible.
13190 Check for integer overflow when computing image height and width.
13192 2011-08-26 Eli Zaretskii <eliz@gnu.org>
13194 * xdisp.c (redisplay_window): Don't force window start if point
13195 will be invisible in the resulting window. (Bug#9324)

13199 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
13200 the display spec is of the form `(space ...)'.
13201 (handle_display_spec): Return the value returned by
13202 handle_single_display_spec, not just 1 or zero.
13203 (handle_single_display_spec): If the display spec is of the form
13204 `(space ...)', and specifies display in the text area, return 2
13206 (try_cursor_movement): Check for the need to scroll more
13207 accurately, and prefer exact match for point under bidi.
13208 Don't advance `row' beyond the last row of the window.
13210 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
13211 into disp_prop; all users changed.
13213 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

13225 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
13226 buffers, return left-to-right.
13227 (set_cursor_from_row): Consider candidate row a win if its glyph
13228 represents a newline and point is on that newline. Fixes cursor
13229 positioning on the newline at EOL of R2L text within L2R
13230 paragraph, and vice versa.
13231 (try_cursor_movement): Check continued rows, in addition to
13232 continuation rows. Fixes unwarranted scroll when point enters a
13233 continued line of R2L text within an L2R paragraph, or vice versa.
13234 (cursor_row_p): Consider the case of point being equal to
13235 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13236 from the end of a short line to the beginning of a continued line
13237 of R2L text within L2R paragraph.
13238 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
13239 composed characters.

13264 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13265 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13266 candidate is selected by the mouse, and that candidate has a
13267 composed character under the mouse.
13269 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13270 coordinates reported by pos-visible-in-window-p for a composed
13271 character in column zero.
13273 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

13277 2011-08-22 Eli Zaretskii <eliz@gnu.org>
13279 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
13280 consider it a hit if to_charpos is anywhere in the range of the
13281 composed buffer positions.
13283 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13285 * image.c (gif_load): Don't assume that each subimage has the same
13286 dimensions as the base image. Handle disposal method that is
13287 "undefined" by the gif spec (Bug#9335).
13289 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13291 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

13297 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13298 from an Org mode buffer to a Speedbar frame.
13300 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13301 a composition, take its buffer position from IT->cmp_it.charpos.
13302 Fixes cursor positioning at the beginning of a line that begins
13303 with a composed character.
13305 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13307 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13308 character bidirectional type, use STRONG_L instead. Fixes crashes
13309 in a buffer produced by `describe-categories'.
13311 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13312 members before the level stack, so they would be saved and
13313 restored when copying iterator state. Fixes incorrect reordering
13314 around TABs covered by display properties.
13316 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

13342 Fix memory allocation problems in Cygwin build (Bug#9273).
13344 * unexcw.c ( __malloc_initialized): Declare external variable.
13345 (fixup_executable): Force the dumped emacs to reinitialize malloc.
13347 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
13349 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

13388 * xdisp.c (move_it_in_display_line_to): Don't invoke
13389 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13390 ppos_it. Fixes vertical cursor motion when line beginning is
13391 covered by an image. (Bug#9296)
13393 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
13395 * nsterm.h (ns_run_ascript): Declare.

13402 the event loop. Get status from as_status (Bug#7276).
13404 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13405 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13406 the event loop (Bug#7276).

13413 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
13414 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
13415 (QCgnutls_bootprop_verify_hostname_error)
13416 (QCgnutls_bootprop_callbacks_verify): Rename from
13417 Qgnutls_bootprop_..., all uses changed.
13419 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
13422 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
13424 * xfaces.c (Qframe_set_background_mode): Now static.
13425 * dispextern.h (Qframe_set_background_mode): Remove decl.
13427 * process.c (Fnetwork_interface_info): Declare local only if needed.
13429 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
13431 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13432 (Fnetwork_interface_list): Allocate in increments of bytes instead
13433 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13434 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13436 (struct ifflag_def): notrailers is smart on OSX.
13437 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13438 Get hardware address with getifaddrs if available.
13440 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13442 * xdisp.c (iterate_out_of_display_property): xassert that
13443 IT->position is set to within IT->object's boundaries. Break from
13444 the loop as soon as EOB is reached; avoids infloops in redisplay
13445 when IT->position is set up wrongly due to some bug.
13446 Set IT->current to match the bidi iterator unconditionally.
13447 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13448 entry. Force push_it to save on the stack the current
13449 buffer/string position, to be restored by pop_it. Fix flags in
13450 the iterator structure wrt the object coming from a display
13451 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13452 properties. (Bug#9284)
13454 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13456 * fontset.c (fontset_get_font_group): Add proper type checks.
13459 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13461 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
13462 and LC_VERSION_MIN_MACOSX.
13463 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
13464 (dump_it) [LC_FUNCTION_STARTS]: Use it.
13466 2011-08-08 Eli Zaretskii <eliz@gnu.org>
13468 * xdisp.c (forward_to_next_line_start): Allow to use the
13469 no-display-properties-and-no-overlays under bidi display.
13470 Set disp_pos in the bidi iterator to avoid searches for display
13471 properties and overlays.
13473 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13475 * editfns.c (Fset_time_zone_rule): Document relationship with the
13478 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
13479 the font entity extracted from the cache (Bug#8109).
13481 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13483 * composite.c (autocmp_chars): Don't reset point. That is done by
13484 restore_point_unwind (Bug#5984).
13486 2011-08-07 Juri Linkov <juri@jurta.org>
13488 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13489 to show the arg `TIME' instead of `TIMEVAL'.
13491 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13493 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13494 display property strides EOL and includes a newline, as in
13495 longlines-mode. (Bug#9254)
13496 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13497 word-wrap under bidirectional display. (Bug#9224)
13499 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13500 is non-zero, even if the data buffer is NULL. Fixes a crash in
13501 vertical-motion with longlines-mode. (Bug#9254)
13503 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13505 * bidi.c <bidi_cache_total_alloc>: Now static.
13506 (bidi_initialize): Initialize bidi_cache_total_alloc.
13508 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13511 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13512 amount allocated this far in `bidi_cache_total_alloc'.
13513 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13514 non-zero, only free the data buffer without restoring the cache
13515 contents. All callers changed.
13517 * dispextern.h (bidi_unshelve_cache): Update prototype.
13519 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13520 (move_it_in_display_line, move_it_to)
13521 (move_it_vertically_backward, move_it_by_lines): Replace the call
13522 to xfree to an equivalent call to bidi_unshelve_cache.
13523 (move_it_in_display_line_to): Fix logic of returning
13524 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13526 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13528 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13529 came from a string character with a `cursor' property. (Bug#9229)
13531 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13533 * Makefile.in (LIB_PTHREAD): New variable.
13534 (LIBES): Add LIB_PTHREAD (Bug#9216).
13536 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13537 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13539 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13541 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13543 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13545 * xterm.c (x_find_topmost_parent): New function.
13546 (x_set_frame_alpha): Find topmost parent window with
13547 x_find_topmost_parent and set the property there also (bug#9181).
13548 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13550 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13552 * callproc.c (Fcall_process): Avoid vfork clobbering
13553 the local vars buffer, coding_systems, current_dir.
13555 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13557 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13559 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13561 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13562 so that it is not optimized away.
13564 * xdisp.c (compute_display_string_pos): Remove unused local.
13566 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13568 Fix slow cursor motion and scrolling in large buffers with
13569 selective display, like Org Mode buffers. (Bug#9218)
13571 * dispextern.h (struct bidi_it): New member disp_prop_p.
13573 * xdisp.c: Remove one-slot cache of display string positions.
13574 (compute_display_string_pos): Accept an additional argument
13575 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13576 for a display string or property. If found, set DISP_PROP_P
13579 * bidi.c (bidi_fetch_char): Accept an additional argument
13580 DISP_PROP_P, and pass it to compute_display_string_pos.
13581 Only handle text covered by a display string if DISP_PROP_P is returned
13582 non-zero. All callers of bidi_fetch_char changed.
13584 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13586 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13588 2010-12-03 Don March <don@ohspite.net>
13590 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13591 last character M-[char] is translated to ESC [char] (bug#7541).
13593 2011-08-02 Kenichi Handa <handa@m17n.org>
13595 * lisp.h (uniprop_table): Extern it.
13597 * chartab.c (uniprop_table): Make it non-static.
13599 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13601 * xdisp.c (forward_to_next_line_start): Accept additional argument
13602 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13604 (reseat_at_next_visible_line_start): Use the bidi iterator state
13605 returned by forward_to_next_line_start to restore the state of
13606 it->bidi_it after backing up to previous newline. (Bug#9212)
13608 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13610 * regex.c (re_comp): Protoize.
13611 (re_exec): Fix return type.
13612 (regexec): Fix type of `ret'. (Bug#9203)
13614 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13616 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13617 This is needed if max-image-size is a floating-point number.
13619 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13621 * print.c (print_object): Print empty symbol as ##.
13623 * lread.c (read1): Read ## as empty symbol.
13625 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13627 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13628 setting frame foreground color (Bug#9175).
13629 (x_set_background_color): Likewise.
13631 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13632 contents (Bug#9176).
13633 (EmacsTooltip -init): Remove bezels and add shadows to
13636 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13637 or scroll bar (Bug#8470).
13639 * nsfont.m (nsfont_open): Remove assignment to voffset and
13640 unnecessary vars hshink, expand, hd, full_height, min_height.
13641 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13643 * nsterm.h (nsfont_info): Remove voffset field.
13645 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13647 Implement strike-through and overline on NextStep (Bug#8863).
13649 * nsfont.m (nsfont_open): Use underline position provided by font,
13650 instead of hard-coded value of 2.
13651 (nsfont_draw): Call ns_draw_text_decoration instead.
13653 * nsterm.h: Add declaration for ns_draw_text_decoration.
13655 * nsterm.m (ns_draw_text_decoration): New function for drawing
13656 underline, overline, and strike-through.
13657 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13658 ns_draw_text_decoration. Change treatment of cursor drawing to
13659 accommodate underlining, etc.
13661 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13663 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13666 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13668 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13669 Without this fix, if a signal arrives just after memory fills up,
13670 'malloc' might be invoked reentrantly.
13672 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13673 In other words, assume that every image size is allowed, on non-X
13674 hosts. This assumption is probably wrong, but it lets Emacs compile.
13676 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13678 * regex.c (re_iswctype): Convert return values to boolean.
13680 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13682 * xdisp.c (compute_display_string_pos): Don't use cached display
13683 string position if the buffer had its restriction changed.
13686 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13688 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13690 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13692 Integer signedness and overflow and related fixes. (Bug#9079)
13694 * bidi.c: Integer size and overflow fixes.
13695 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13696 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13697 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13698 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13699 (bidi_find_other_level_edge):
13700 Use ptrdiff_t instead of EMACS_INT where either will do.
13701 This works better on 32-bit hosts configured --with-wide-int.
13702 (bidi_cache_ensure_space): Check for size-calculation overflow.
13703 Use % rather than repeated addition, for better worst-case speed.
13704 Don't set bidi_cache_size until after xrealloc returns, because it
13706 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13707 (bidi_cache_ensure_space): Also check that the bidi cache size
13708 does not exceed that of the largest Lisp string or buffer. See Eli
13709 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13711 * alloc.c (__malloc_size_t): Remove.
13712 All uses replaced by size_t. See Andreas Schwab's note
13713 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13715 * image.c: Improve checking for integer overflow.
13716 (check_image_size): Assume that f is nonnull, since
13717 it is always nonnull in practice. This is one less thing to
13718 worry about when checking for integer overflow later.
13719 (x_check_image_size): New function, which checks for integer
13720 overflow issues inside X.
13721 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13722 This removes the need for a memory_full check.
13723 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13724 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13725 (xbm_read_bitmap_data): Change locals back to 'int', since
13726 their values must fit in 'int'.
13727 (xpm_load_image, png_load, tiff_load):
13728 Invoke x_create_x_image_and_pixmap earlier,
13729 to avoid much needless work if the image is too large.
13730 (tiff_load): Treat overly large images as if
13731 x_create_x_image_and_pixmap failed, not as malloc failures.
13732 (gs_load): Use x_check_image_size.
13734 * gtkutil.c: Omit integer casts.
13735 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13736 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13738 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13740 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13741 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13742 would wrongly return t on a 64-bit host.
13744 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13745 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13746 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13747 and therefore cause GCC to emit a bogus diagnostic in some cases.
13749 * image.c: Integer signedness and overflow and related fixes.
13750 This is not an exhaustive set of fixes, but it's time to
13751 record what I've got.
13752 (lookup_pixel_color, check_image_size): Remove redundant decls.
13753 (check_image_size): Don't assume that arbitrary EMACS_INT values
13754 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13755 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13756 (tiff_load, imagemagick_load_image):
13757 Check for overflow in size calculations.
13758 (x_create_x_image_and_pixmap): Remove unnecessary test for
13759 xmalloc returning NULL; that can't happen.
13760 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13761 (xpm_color_bucket): Use better integer hashing function.
13762 (xpm_cache_color): Don't possibly over-allocate memory.
13763 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13764 (gif_memory_source):
13765 Use ptrdiff_t, not int or size_t, to record sizes.
13766 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13767 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13768 either works, as we prefer signed integers.
13769 (tiff_read_from_memory, tiff_write_from_memory):
13770 Return tsize_t, not size_t, since that's what the TIFF API wants.
13771 (tiff_read_from_memory): Don't fail simply because the read would
13772 go past EOF; instead, return a short read.
13773 (tiff_load): Omit no-longer-needed casts.
13774 (Fimagemagick_types): Don't assume size fits into 'int'.
13776 Improve hashing quality when configured --with-wide-int.
13777 * fns.c (hash_string): New function, taken from sxhash_string.
13778 Do not discard information about ASCII character case; this
13779 discarding is no longer needed.
13780 (sxhash-string): Use it. Change sig to match it. Caller changed.
13781 * lisp.h: Declare it.
13782 * lread.c (hash_string): Remove, since we now use fns.c's version.
13783 The fns.c version returns a wider integer if --with-wide-int is
13784 specified, so this should help the quality of the hashing a bit.
13786 * emacs.c: Integer overflow minor fix.
13787 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13788 Define only if GNU_LINUX.
13789 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13791 * dispnew.c: Integer signedness and overflow fixes.
13792 Remove unnecessary forward decls, that were a maintenance hassle.
13793 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13795 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13796 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13797 (prepare_desired_row, line_draw_cost):
13798 Use int, not unsigned, where either works.
13799 (save_current_matrix, restore_current_matrix):
13800 Use ptrdiff_t, not size_t, where either works.
13801 (init_display): Check for overflow more accurately, and without
13802 relying on undefined behavior.
13804 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13805 Remove, replacing with the new symbols in lisp.h. All uses changed.
13806 * fileio.c (make_temp_name):
13807 * filelock.c (lock_file_1, lock_file):
13808 * xdisp.c (message_dolog):
13809 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13810 Use pMd etc. instead.
13811 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13812 replacing the pWIDE etc. symbols removed from editfns.c.
13814 * keyboard.h (num_input_events): Now uintmax_t.
13815 This is (very slightly) less likely to mess up due to wraparound.
13818 * buffer.c: Integer signedness fixes.
13819 (alloc_buffer_text, enlarge_buffer_text):
13820 Use ptrdiff_t rather than size_t when either will do, as we prefer
13823 * alloc.c: Integer signedness and overflow fixes.
13824 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13825 (__malloc_size_t): Default to size_t, not to int.
13826 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13827 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13828 Prefer ptrdiff_t to size_t when either would do, as we prefer
13830 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13831 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13832 Now const. Initialize with values that are in range even if char
13834 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13835 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13836 These functions do the right thing with sizes > 2**32.
13837 (check_depth): Now ptrdiff_t, not int.
13838 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13839 Adjust to new way of storing sizes. Check for size overflow bugs
13841 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13842 slightly wrong anyway, as it missed one instance of
13843 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13844 (refill_memory_reserve): Omit needless cast to size_t.
13845 (mark_object_loop_halt): Mark as externally visible.
13847 * xselect.c: Integer signedness and overflow fixes.
13848 (Fx_register_dnd_atom, x_handle_dnd_message):
13849 Use ptrdiff_t, not size_t, since we prefer signed.
13850 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13851 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13852 x_dnd_atoms_size and x_dnd_atoms_length.
13854 * doprnt.c: Prefer signed to unsigned when either works.
13856 * doprnt.c (doprnt):
13858 * xdisp.c (vmessage):
13859 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13860 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13861 prefer signed arithmetic to avoid comparison confusion.
13862 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13863 but is a bit tricky.
13865 Assume freestanding C89 headers, string.h, stdlib.h.
13866 * data.c, doprnt.c, floatfns.c, print.c:
13867 Include float.h unconditionally.
13868 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13869 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13870 * regex.c: Likewise for stddef.h, string.h.
13871 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13872 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13873 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13874 (STDC_HEADERS): Remove obsolete defines.
13875 * sysdep.c: Include limits.h unconditionally.
13877 Assume support for memcmp, memcpy, memmove, memset.
13878 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13879 * regex.c (memcmp, memcpy):
13880 Remove; we assume C89 now.
13882 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13883 (__malloc_safe_bcopy): Remove; no longer needed.
13885 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13886 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13887 well either way, and we prefer signed to unsigned.
13889 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13891 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13892 closes the connection while we're reading (bug#9182).
13894 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13896 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13897 are specified (Bug#9168).
13899 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13901 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13902 Found by GCC static checking and --with-wide-int on a 32-bit host.
13904 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13906 * xdisp.c (compute_display_string_pos): Fix logic of caching
13907 previous display string position. Initialize cached_prev_pos to
13908 -1. Fixes slow-down at the beginning of a buffer.
13910 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13912 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13913 for attrs[LFACE_FONTSET_INDEX].
13915 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13917 * xml.c (parse_region): Remove unused local
13918 that was recently introduced.
13920 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13922 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13923 revision 84777 on 2008-02-22.
13925 * xdisp.c (move_it_in_display_line_to): Record the best matching
13926 position for TO_CHARPOS while scanning the line, and restore it on
13927 exit if none of the characters scanned was an exact match.
13928 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13929 when exact match is impossible due to invisible text, and the
13930 lines are truncated.
13932 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13934 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13937 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13939 Fix a significant slow-down of cursor motion with C-n, C-p,
13940 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13941 auto-repeat under bidi redisplay in fontified buffers.
13942 * xdisp.c (compute_stop_pos_backwards): New function.
13943 (next_element_from_buffer): Call compute_stop_pos_backwards to
13944 find a suitable prev_stop when we find ourselves before
13946 (reseat): Don't look for prev_stop, as that could mean a very long
13948 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13949 <cached_disp_overlay_modiff>: Cache for last found display string
13951 (compute_display_string_pos): Return the cached position if asked
13952 about the same buffer in the same area of character positions, and
13953 the buffer wasn't changed since the time the display string
13954 position was cached.
13956 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13958 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13959 is an integer, which is important for empty lines. (Bug#9149)
13961 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13963 * frame.c (Fmodify_frame_parameters): In tty case, update the
13964 default face if necessary (Bug#4238).
13966 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13968 * editfns.c (Fstring_to_char): No need to explain what a character
13969 is in the docstring (Bug#6576).
13971 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13973 * xml.c (parse_region): Make sure we always return a tree.
13975 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13977 * xml.c (parse_region): If a document contains only comments,
13980 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13982 * xml.c (make_dom): Return comments, too.
13984 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13987 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13988 and the surrounding thread.
13989 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13990 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13991 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13993 * s/openbsd.h (BROKEN_SIGIO): Define.
13994 * unexelf.c (unexec) [__OpenBSD__]:
13995 Don't update the .mdebug section of the Alpha COFF symbol table.
13997 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13999 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14002 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14004 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14005 This fixes some race conditions on the permissions of any newly
14008 * alloc.c (valid_pointer_p): Use pipe, not open.
14009 This fixes some permissions issues when debugging.
14011 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14012 If fchown fails to set both uid and gid, try to set just gid,
14013 as that is sometimes allowed. Adjust the file's mode to eliminate
14014 setuid or setgid bits that are inappropriate if fchown fails.
14016 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14018 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14019 to compare Lisp_Objects.
14020 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14021 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14022 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14024 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14026 * lread.c (read_integer): Unread even EOF character.
14027 (read1): Likewise. Properly record start position of symbol.
14029 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14030 symbol character follows.
14032 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14034 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14035 This works around a problem with the previous change to Fcopy_file.
14036 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14037 and without this change, GCC might complain about discarding
14038 fchown's return value.
14040 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14042 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14044 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14046 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14048 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14050 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14051 it's used from the C level.
14053 * process.c: Use the same condition for POLL_FOR_INPUT in both
14054 keyboard.c and process.c (bug#1858).
14056 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14058 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14059 (Fgnutls_boot): Use it.
14061 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14063 * doc.c (Fsubstitute_command_keys): Revert last change.
14065 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14067 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14068 quotes the next character, and doesn't affect other longer
14069 sequences (bug#8935).
14071 * lread.c (syms_of_lread): Clarify that is isn't only
14072 `eval-buffer' and `eval-defun' that's affected by
14073 `lexical-binding' (bug#8460).
14075 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14077 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14078 bidi redisplay when a line includes both an image and is truncated.
14080 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14082 Fix minor problems found by static checking.
14083 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14084 (elsz): Now a signed constant, not a size_t var. We prefer signed
14085 types to unsigned, to avoid integer comparison confusion. Without
14086 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14087 "cannot optimize loop, the loop counter may overflow", a symptom
14089 * indent.c (Fvertical_motion): Mark locals as initialized.
14090 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14092 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14094 * search.c (Fre_search_backward): Mention `case-fold-search' in
14095 all the re_search_* functions (bug#8138).
14097 * keyboard.c (Fopen_dribble_file): Document when the file is

14108 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
14109 (reseat_to_string): Initialize bidi_it->string.s and
14110 bidi_it->string.schars.
14111 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
14112 NULL (avoids a crash in bidi_paragraph_init).
14113 Initialize itb.string.lstring.
14114 (init_iterator): Call bidi_init_it only of a valid
14115 buffer position was specified. Initialize paragraph_embedding to
14117 (reseat_to_string): Initialize the bidi iterator.
14118 (display_string): If we need to ignore text properties of
14119 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14120 original value of -1 will not work with bidi.)
14121 (compute_display_string_pos): First arg is now struct
14122 `text_pos *'; all callers changed. Support display properties on
14124 (compute_display_string_end): Support display properties on Lisp
14126 (init_iterator, reseat_1, reseat_to_string): Initialize the
14127 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
14128 when iterating on a string not from display properties).
14129 (compute_display_string_pos, compute_display_string_end):
14130 Fix calculation of the object to scan. Fixes an error when using
14132 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
14133 base_level_stop; instead, set base_level_stop to BEGV.
14134 Fixes crashes in vertical-motion.
14135 (next_element_from_buffer): Improve commentary for when
14136 the iterator is before prev_stop.
14137 (init_iterator): Initialize bidi_p from the default value of
14138 bidi-display-reordering, not from buffer-local value. Use the
14139 buffer-local value only if initializing for buffer iteration.
14140 (handle_invisible_prop): Support invisible properties on strings
14141 that are being bidi-reordered.
14142 (set_iterator_to_next): Support bidi reordering of C strings and
14144 (next_element_from_string): Support bidi reordering of Lisp
14146 (handle_stop_backwards): Support Lisp strings as well.
14147 (display_string): Support display of R2L glyph rows.
14148 Use IT_STRING_CHARPOS when displaying from a Lisp string.
14149 (init_iterator): Don't initialize it->bidi_p for strings
14151 (reseat_to_string): Initialize it->bidi_p for strings here.
14152 (next_element_from_string, next_element_from_c_string)
14153 (next_element_from_buffer): Add xassert's for correspondence
14154 between IT's object being iterated and it->bidi_it.string

14158 character that is not the first one in the visual order.
14159 (get_visually_first_element): New function, refactored from common
14160 parts of next_element_from_buffer, next_element_from_string, and
14161 next_element_from_c_string.
14162 (tool_bar_lines_needed, redisplay_tool_bar)
14163 (display_menu_bar): Force left-to-right direction. Add a FIXME
14164 comment for making that be controlled by a user option.
14165 (push_it, pop_it): Save and restore the state of the
14166 bidi iterator. Save and restore the bidi_p flag.
14167 (pop_it): Iterate out of display property for string iteration as
14169 (iterate_out_of_display_property): Support iteration over strings.
14170 (handle_single_display_spec): Set up it->bidi_it for iteration
14171 over a display string, and call bidi_init_it.
14172 (handle_single_display_spec, next_overlay_string)
14173 (get_overlay_strings_1, push_display_prop): Set up the bidi
14174 iterator for displaying display or overlay strings.
14175 (forward_to_next_line_start): Don't use the shortcut if
14177 (back_to_previous_visible_line_start): If handle_display_prop
14178 pushed the iterator stack, restore the internal state of the bidi
14179 iterator by calling bidi_pop_it same number of times.
14180 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
14181 and we are bidi-iterating, don't decrement the iterator position;
14182 instead, set the first_elt flag in the bidi iterator, to produce
14184 (reseat_1): Remove redundant setting of string_from_display_prop_p.
14185 (push_display_prop): xassert that we are iterating a buffer.
14186 (push_it, pop_it): Save and restore paragraph_embedding member.
14187 (handle_single_display_spec, next_overlay_string)
14188 (get_overlay_strings_1, reseat_1, reseat_to_string)
14189 (push_display_prop): Set up the `unibyte' member of bidi_it.string
14190 correctly. Don't assume unibyte strings are not bidi-reordered.
14191 (compute_display_string_pos)
14192 (compute_display_string_end): Fix handling the case of C string.
14193 (push_it, pop_it): Save and restore from_disp_prop_p.

14198 popping after iteration over a string that came from a display
14199 property. Fix a typo in popping stretch info. Add an assertion
14200 for verifying that the iterator position is in sync with the bidi
14202 (handle_single_display_spec, get_overlay_strings_1)
14203 (push_display_prop): Fix initialization of paragraph direction for
14204 string when that of the parent object is not yet determined.

14206 iterator with IT's position. (Bug#7616)
14207 (find_row_edges): If ROW->start.pos gives position
14208 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

14210 Reset the from_disp_prop_p flag.
14211 (SAVE_IT, RESTORE_IT): New macros.

14215 (move_it_to, move_it_vertically_backward, move_it_by_lines)
14216 (try_scrolling, redisplay_window, display_line): Use them when
14217 saving a temporary copy of the iterator and restoring it back.
14218 (back_to_previous_visible_line_start, reseat_1)
14219 (init_iterator): Empty the bidi cache "stack".
14220 (move_it_in_display_line_to): If iterator ended up at
14221 EOL, but we never saw any buffer positions smaller than
14222 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
14223 motion in bidi-reordered lines.
14224 (move_it_in_display_line_to): Record prev_method and prev_pos
14225 immediately before the call to set_iterator_to_next. Fixes cursor
14226 motion in bidi-reordered lines with stretch glyphs and strings
14227 displayed in margins. (Bug#8133) (Bug#8867)
14228 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
14230 (pos_visible_p): Support positions in bidi-reordered lines.
14231 Save and restore bidi cache.
14233 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
14234 (bidi_paragraph_info): Delete unused struct.
14235 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
14236 (bidi_cache_start): New variable.
14237 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

14245 (bidi_fetch_char): Accept new argument STRING; all callers
14246 changed. Support iteration over a string. Support strings with
14247 display properties. Support unibyte strings. Fix the type of
14248 `len' according to what STRING_CHAR_AND_LENGTH expects.
14249 (bidi_paragraph_init, bidi_resolve_explicit_1)
14250 (bidi_resolve_explicit, bidi_resolve_weak)
14251 (bidi_level_of_next_char, bidi_move_to_visually_next):
14252 Support iteration over a string.
14253 (bidi_set_sor_type, bidi_resolve_explicit_1)
14254 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
14255 can now be zero (for strings); special values 0 and -1 were
14256 changed to -1 and -2, respectively.
14257 (bidi_char_at_pos): New function.
14258 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
14259 Call it instead of FETCH_MULTIBYTE_CHAR.

14269 (bidi_initialize): Initialize the bidi cache start stack pointer.
14270 (bidi_cache_ensure_space): New function, refactored from part of

14274 (bidi_count_bytes, bidi_char_at_pos): New functions.
14275 (bidi_cache_search): Don't assume bidi_cache_last_idx is

14277 (bidi_cache_find_level_change): xassert that bidi_cache_last_idx
14278 is valid if it's going to be used.

14342 Vx_lost_selection_functions to Frun_hook_with_args.
14344 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
14346 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
14347 The old code sometimes used this field without initializing it.
14349 * alloc.c (gc_sweep): Don't read past end of array.
14350 In theory, the old code could also have corrupted Emacs internals,
14351 though it'd be very unlikely.

14355 * character.c (Fcharacterp): Don't advertise optional ignored

14454 Use pthread_sigmask, not sigprocmask (Bug#9010).
14455 sigprocmask is portable only for single-threaded applications, and
14456 Emacs can be multi-threaded when it uses GTK.

14614 (clone_per_buffer_values): Don't assume that

14616 This isn't true in general, and it's particularly not true
14617 if Emacs is configured with --with-wide-int.
14618 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
14619 New macros, used in the buffer.c change.

14655 Random fixes. E.g., (random) never returned negative values.
14656 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14657 subseconds part to the entropy, as that's a bit more random.
14658 Prefer signed to unsigned, since the signedness doesn't matter and
14659 in general we prefer signed. When given a limit, use a
14660 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14661 latter isn't right if USE_2_TAGS_FOR_INTS.
14662 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14663 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14673 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
14675 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14676 This is more efficient than Ffile_directory_p and avoids a minor race.
14678 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14680 * buffer.c (Foverlay_put): Say what the return value is
14683 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14684 is a directory before asking whether to use the file name
14686 (barf_or_query_if_file_exists): Make the "File is a directory"
14687 error be more correct.
14689 * fns.c (Frequire): Remove the mention of the .gz files, since
14690 that's installation-specific, but keep the mention of
14691 `get-load-suffixes'.

14695 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

14703 Qgnutls_bootprop_verify_error (which is no longer used).
14705 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14706 unused since revno:102982 (2011-01-26). All callers changed.
14707 Also (re)move comments that are misplaced or no longer relevant.
14709 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14711 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

14732 leave any prefix arg for the up event (Bug#1586).
14734 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
14736 * lread.c (syms_of_lread): Mention single symbols defined by

14808 * eval.c (struct backtrace): Simplify and port the data structure.
14809 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14810 signed bit field, as this assumption is not portable and it makes
14811 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14812 "char debug_on_exit : 1" as this is not portable either; instead,
14813 use the portable "unsigned int debug_on_exit : 1". Remove unused
14814 member evalargs. Remove obsolete comments about cc bombing out.

15004 (read1): Check for integer overflow in radices, and in
15005 read-circle numbers.
15006 (read_escape): Avoid int overflow.
15007 (Fload, openp, read_buffer_size, read1)
15008 (substitute_object_recurse, read_vector, read_list, map_obarray):

15049 on undefined behavior with wrong number of arguments.
15050 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15051 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15052 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15053 since we're not interested in debugging glyphs with old libraries.
15054 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15055 GCC 4.6.0's static checking.

15148 Use memcpy, not strncpy, where memcpy is what is really wanted.
15149 Don't assume (via atoi) that time_t and pid_t fit in int.
15150 Check for time_t and/or pid_t out of range, e.g., via a network share.
15151 Don't alloca where an auto var works fine.

15176 * callproc.c (getenv_internal_1, getenv_internal)
15177 (Fgetenv_internal):
15178 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15180 * lread.c (invalid_syntax): Omit length argument.
15181 All uses changed. This doesn't fix a bug, but it simplifies the
15182 code away from its former Hollerith-constant appearance, and it's
15183 one less 'int' to worry about when looking at integer-overflow issues.
15184 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15186 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15187 This didn't break anything, but it didn't help either.
15188 It's confusing to put a bogus integer in a place where the actual
15189 value does not matter.
15190 (LIST_END_P): Remove unused macro and its bogus comment.
15191 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15193 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15194 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15196 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15197 We prefer signed types, and the value cannot exceed the EMACS_INT
15198 range anyway (because otherwise the length would not be representable).
15199 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15200 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15201 This avoids a GCC warning when WIDE_EMACS_INT.
15203 * indent.c (sane_tab_width): New function.
15204 (current_column, scan_for_column, Findent_to, position_indentation)
15205 (compute_motion): Use it. This is just for clarity.
15206 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15208 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15210 * lisp.h (lint_assume): New macro.
15211 * composite.c (composition_gstring_put_cache):
15212 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15214 * editfns.c, insdel.c:
15215 Omit unnecessary forward decls, to simplify future changes.
15217 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15219 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15221 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15222 Use much-faster test for byte-length change.
15223 Don't assume string byte-length fits in 'int'.
15224 Check that character arg fits in 'int'.
15225 (mapcar1): Declare byte as byte, for clarity.
15227 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15229 * fns.c (concat): Catch string overflow earlier.
15230 Do not rely on integer wraparound.
15232 * dispextern.h (struct it.overlay_strings_charpos)
15233 (struct it.selective): Now EMACS_INT, not int.
15234 * xdisp.c (forward_to_next_line_start)
15235 (back_to_previous_visible_line_start)
15236 (reseat_at_next_visible_line_start, next_element_from_buffer):
15237 Don't arbitrarily truncate the value of 'selective' to int.
15239 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15241 * composite.c: Don't truncate sizes to 'int'.
15242 (composition_gstring_p, composition_reseat_it)
15243 (composition_adjust_point): Use EMACS_INT, not int.
15244 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15245 not EMACS_UINT, for indexes.
15247 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15249 * buffer.c: Include <verify.h>.
15250 (struct sortvec.priority, struct sortstr.priority):
15251 Now EMACS_INT, not int.
15252 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15253 (struct sortstr.size, record_overlay_string)
15254 (struct sortstrlist.size, struct sortlist.used):
15255 Don't truncate size to int.
15256 (record_overlay_string): Check for size-calculation overflow.
15257 (init_buffer_once): Check at compile-time, not run-time.
15259 2011-06-22 Jim Meyering <meyering@redhat.com>
15261 Don't leak an XBM-image-sized buffer
15262 * image.c (xbm_load): Free the image buffer after using it.
15264 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15267 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15268 that Sun C diagnosed.
15269 * fns.c (secure_hash): Fix pointer signedness issue.
15270 * intervals.c (static_offset_intervals): New function.
15271 (offset_intervals): Use it.
15273 2011-06-21 Leo Liu <sdl.web@gmail.com>
15276 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15279 * fns.c (secure_hash): Rename from crypto_hash_function and change
15280 the first arg to accept symbols.
15281 (Fsecure_hash): New primitive.
15282 (syms_of_fns): New symbols.
15284 2011-06-20 Deniz Dogan <deniz@dogan.se>
15286 * process.c (Fset_process_buffer): Clarify return value in
15289 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15291 * dispnew.c (add_window_display_history): Use BVAR.
15293 * xdisp.c (debug_method_add): Use BVAR.
15294 (check_window_end, dump_glyph_matrix, dump_glyph)
15295 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15297 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15300 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15301 check till after the cache is created in init_frame_faces.
15303 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15305 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15307 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15309 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15310 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15311 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15313 Improve buffer-overflow checking (Bug#8873).
15314 * fileio.c (Finsert_file_contents):
15315 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15316 Remove the old (too-loose) buffer overflow checks.
15317 They weren't needed, since make_gap checks for buffer overflow.
15318 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15319 The old code merely checked for Emacs fixnum overflow, and relied
15320 on undefined (wraparound) behavior. The new code avoids undefined
15321 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15323 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15324 Tune. Don't use wider integers than needed. Don't use alloca.
15325 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15327 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15329 * insdel.c, lisp.h (buffer_overflow): New function.
15330 (insert_from_buffer_1, replace_range, replace_range_2):
15331 * insdel.c (make_gap_larger):
15332 * editfns.c (Finsert_char):
15333 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15335 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15337 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15339 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15341 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15342 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15344 * fileio.c: Don't assume EMACS_INT fits in off_t.
15345 (emacs_lseek): New static function.
15346 (Finsert_file_contents, Fwrite_region): Use it.
15347 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15349 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15351 * fns.c: Don't overflow int when computing a list length.
15352 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15353 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15354 truncation on 64-bit hosts. Check for QUIT every
15355 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15356 faster and is responsive enough.
15357 (Flength): Report an error instead of overflowing an integer.
15358 (Fsafe_length): Return a float if the value is not representable
15359 as a fixnum. This shouldn't happen except in contrived situations.
15360 (Fnthcdr, Fsort): Don't assume list length fits in int.
15361 (Fcopy_sequence): Don't assume vector length fits in int.
15363 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15364 (header_size, word_size): New constants.
15365 (allocate_vectorlike): Don't check size overflow here.
15366 (allocate_vector): Check it here instead, since this is the only
15367 caller of allocate_vectorlike that could cause overflow.
15368 Check that the new vector's length is representable as a fixnum.
15370 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15371 The previous code was bogus. For example, next_almost_prime (32)
15372 returned 39, which is undesirable as it is a multiple of 3; and
15373 next_almost_prime (24) returned 25, which is a multiple of 5 so
15374 why was the code bothering to check for multiples of 7?
15376 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15378 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15380 Variadic C functions now count arguments with ptrdiff_t.
15381 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15382 Back then I didn't know that the Emacs coding style prefers signed int.
15383 Also, in the meantime I found a few more instances where arguments
15384 were being counted with int, which may truncate counts on 64-bit
15385 machines, or EMACS_INT, which may be unnecessarily wide.
15386 * lisp.h (struct Lisp_Subr.function.aMANY)
15387 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15388 Arg counts are now ptrdiff_t, not size_t.
15389 All variadic functions and their callers changed accordingly.
15390 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15391 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15392 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15393 * callint.c (Fcall_interactively): Check arg count for overflow,
15394 to avoid potential buffer overrun. Use signed char, not 'int',
15395 for 'varies' array, so that we needn't bother to check its size
15396 calculation for overflow.
15397 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15398 * eval.c (apply_lambda):
15399 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15400 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15401 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15403 * callint.c (Fcall_interactively): Don't use index var as event count.
15405 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15406 * mem-limits.h (SIZE): Remove; no longer used.
15408 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15410 Remove unnecessary casts.
15411 * xterm.c (x_term_init):
15412 * xfns.c (x_set_border_pixel):
15413 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15414 These aren't needed now that we assume ANSI C.
15416 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15417 It's more likely to cause problems (due to unsigned overflow)
15420 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15422 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15424 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15426 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15428 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15430 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15432 GLYPH_CODE_FACE returns EMACS_INT, not int.
15433 * dispextern.h (merge_faces):
15434 * xfaces.c (merge_faces):
15435 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15436 Don't assume EMACS_INT fits in int.
15438 * character.h (CHAR_VALID_P): Remove unused parameter.
15439 * fontset.c, lisp.h, xdisp.c: All uses changed.
15441 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15443 * fns.c (concat): Minor tuning based on overflow analysis.
15444 This doesn't fix any bugs. Use int to hold character, instead
15445 of constantly refetching from Emacs object. Use XFASTINT, not
15446 XINT, for value known to be a character. Don't bother comparing
15447 a single byte to 0400, as it's always less.
15449 * floatfns.c (Fexpt):
15450 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15452 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15455 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15457 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15458 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15459 incorrectly succeed when S was a string, because 4294967386 was
15460 truncated before it was used.
15462 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15463 Otherwise, an out-of-range integer could cause undefined behavior
15466 * composite.c: Use int, not EMACS_INT, for characters.
15467 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15468 EMACS_INT, for values that are known to be in character range.
15469 This doesn't fix any bugs but is the usual style inside Emacs and
15470 may generate better code on 32-bit machines.
15472 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15473 This is for reasons similar to the recent CHAR_STRING fix.
15474 * charset.c (Fencode_char): Check that character arg is actually
15475 a character. Pass an int to ENCODE_CHAR.
15476 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15477 wider than 'int', as a compile-time check to prevent future regressions
15480 * character.c (char_string): Remove unnecessary casts.
15482 Make sure a 64-bit char is never passed to CHAR_STRING.
15483 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15484 by silently ignoring the top 32 bits, allowing some values
15485 that were far too large to be valid characters.
15486 * character.h: Include <verify.h>.
15487 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15488 arguments are no wider than unsigned, as a compile-time check
15489 to prevent future regressions in this area.
15491 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15492 (Fsubst_char_in_region):
15494 * xdisp.c (decode_mode_spec_coding):
15495 Adjust to CHAR_STRING's new requirement.
15496 * editfns.c (Finsert_char, Fsubst_char_in_region):
15497 * fns.c (concat): Check that character args are actually
15498 characters. Without this test, these functions did the wrong
15499 thing with wildly out-of-range values on 64-bit hosts.
15501 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15502 These casts should not be needed on 32-bit hosts, either.
15503 * keyboard.c (read_char):
15504 * lread.c (Fload): Remove casts to unsigned.
15506 * lisp.h (UNSIGNED_CMP): New macro.
15507 This fixes comparison bugs on 64-bit hosts.
15508 (ASCII_CHAR_P): Use it.
15509 * casefiddle.c (casify_object):
15510 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15511 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15512 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15513 * dispextern.h (FACE_FROM_ID):
15514 * keyboard.c (read_char): Use UNSIGNED_CMP.
15516 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15517 not to EMACS_INT, to avoid GCC warning.
15519 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15521 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15522 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15523 isn't needed on 32-bit machines.
15525 * buffer.c (Fgenerate_new_buffer_name):
15526 Use EMACS_INT for count, not int.
15527 (advance_to_char_boundary): Return EMACS_INT, not int.
15529 * data.c (Qcompiled_function): Now static.
15531 * window.c (window_body_lines): Now static.
15533 * image.c (gif_load): Rename local to avoid shadowing.
15535 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15536 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15537 * alloc.c (make_save_value): Integer argument is now of type
15538 ptrdiff_t, not int.
15539 (mark_object): Use ptrdiff_t, not int.
15540 * lisp.h (pD): New macro.
15541 * print.c (print_object): Use it.
15543 * alloc.c: Use EMACS_INT, not int, to count objects.
15544 (total_conses, total_markers, total_symbols, total_vector_size)
15545 (total_free_conses, total_free_markers, total_free_symbols)
15546 (total_free_floats, total_floats, total_free_intervals)
15547 (total_intervals, total_strings, total_free_strings):
15548 Now EMACS_INT, not int. All uses changed.
15549 (Fgarbage_collect): Compute overall total using a double, so that
15550 integer overflow is less likely to be a problem. Check for overflow
15551 when converting back to an integer.
15552 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15553 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15554 These were 'int' variables that could overflow on 64-bit hosts;
15555 they were never used, so remove them instead of repairing them.
15556 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15557 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15558 Previously, this ceilinged at INT_MAX, but that doesn't work on
15560 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15562 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15563 (allocate_vectorlike): Check for ptrdiff_t overflow.
15564 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15565 when a (possibly-narrower) signed value would do just as well.
15566 We prefer using signed arithmetic, to avoid comparison confusion.
15568 * alloc.c: Catch some string size overflows that we were missing.
15569 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15570 for convenience in STRING_BYTES_MAX.
15571 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15572 The definition here is exact; the one in lisp.h was approximate.
15573 (allocate_string_data): Check for string overflow. This catches
15574 some instances we weren't catching before. Also, it catches
15575 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15576 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15577 and ptrdiff_t and EMACS_INT are both 64 bits.
15579 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15580 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15581 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15583 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15585 * alloc.c (Fmake_string): Check for out-of-range init.
15587 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15589 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15591 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15593 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15594 xg_get_default_scrollbar_width.
15596 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15597 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15598 (style_changed_cb): Call update_theme_scrollbar_width and call
15599 x_set_scroll_bar_default_width and xg_frame_set_char_size for
15600 all frames (Bug#8505).
15601 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
15602 Call gtk_window_set_resizable if HAVE_GTK3.
15603 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
15604 and height if HAVE_GTK3 (Bug#8505).
15605 (scroll_bar_width_for_theme): New variable.
15606 (update_theme_scrollbar_width): New function.
15607 (xg_get_default_scrollbar_width): Move code to
15608 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15609 (xg_initialize): Call update_theme_scrollbar_width.
15611 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.

16077 (Fwindow_minibuffer_p): Move up in code and simplify.
16078 (Fset_frame_selected_window): Move here from frame.c.
16080 (Fselected_window, select_window, Fselect_window): Move up in
16081 code. Minor doc-string fixes.
16083 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
16085 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
16086 Do not assume that spare memory exists; that assumption is valid
16087 only if SYSTEM_MALLOC.
16088 (LARGE_REQUEST): New macro, so that the issue of large requests
16089 is separated from the issue of spare memory.
16091 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
16093 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

16119 New error handlers.
16120 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
16121 Obey Vx_select_enable_clipboard_manager. Catch errors in
16122 x_clipboard_manager_save (Bug#8779).
16123 (Vx_select_enable_clipboard_manager): New variable.
16124 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
16126 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
16128 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
16130 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16132 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
16133 in the current matrix if keep_current_p is non-zero.

16137 * bidi.c (bidi_level_of_next_char): Fix last change.
16139 2011-06-03 Eli Zaretskii <eliz@gnu.org>
16141 Support bidi reordering of text covered by display properties.
16143 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
16144 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
16145 (bidi_cache_search, bidi_cache_iterator_state)
16146 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
16147 (bidi_level_of_next_char, bidi_move_to_visually_next):
16148 Support character positions inside a run of characters covered by a
16150 (bidi_paragraph_init, bidi_resolve_explicit_1)
16151 (bidi_level_of_next_char): Call bidi_fetch_char and
16152 bidi_fetch_char_advance instead of FETCH_CHAR and
16153 FETCH_CHAR_ADVANCE.

16155 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
16157 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
16158 instead of using explicit *_CHAR codes.
16159 (bidi_resolve_explicit, bidi_resolve_weak):
16160 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
16161 bidirectional text is supported only in multibyte buffers.
16162 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
16163 it to initialize the frame_window_p member of struct bidi_it.
16164 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
16165 (bidi_resolve_explicit, bidi_resolve_weak)

16167 bidi_it->nchars is non-positive.
16168 (bidi_level_of_next_char): Don't try to lookup the cache for the
16169 next/previous character if nothing is cached there yet, or if we
16170 were just reseat()'ed to a new position.
16172 * xdisp.c (set_cursor_from_row): Set start and stop points
16173 according to the row's direction when priming the loop that looks
16174 for the glyph on which to display cursor.
16175 (single_display_spec_intangible_p): Function deleted.
16176 (display_prop_intangible_p): Reimplement to call
16177 handle_display_spec instead of single_display_spec_intangible_p.
16178 Accept 3 additional arguments needed by handle_display_spec.
16179 This fixes incorrect cursor motion across display property with complex
16180 values: lists, `(when COND...)' forms, etc.
16181 (single_display_spec_string_p): Support property values that are
16182 lists with the argument STRING its top-level element.
16183 (display_prop_string_p): Fix the condition for processing a
16184 property that is a list to be consistent with handle_display_spec.
16185 (handle_display_spec): New function, refactored from the
16186 last portion of handle_display_prop.
16187 (compute_display_string_pos): Accept additional argument
16188 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
16189 value of a `display' property is a "replacing spec".
16190 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16191 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
16192 the display property, but just return a value indicating whether
16193 the display property will replace the characters it covers.
16194 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
16195 frame_window_p members of struct bidi_it.
16196 (compute_display_string_pos, compute_display_string_end):
16198 (push_it): Accept second argument POSITION, where pop_it should
16199 jump to continue iteration.
16200 (reseat_1): Initialize bidi_it.disp_pos.
16202 * keyboard.c (adjust_point_for_property): Adjust the call to
16203 display_prop_intangible_p to its new signature.
16205 * dispextern.h (struct bidi_it): New member frame_window_p.
16206 (bidi_init_it): Update prototypes.
16207 (display_prop_intangible_p): Update prototype.
16208 (compute_display_string_pos, compute_display_string_end):
16209 Declare prototypes.
16210 (struct bidi_it): New members nchars and disp_pos. ch_len is now
16213 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
16215 Malloc failure behavior now depends on size of allocation.
16216 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
16217 * lisp.h: Change signatures accordingly.
16218 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
16219 All callers changed. (Bug#8762)
16221 * gnutls.c: Use Emacs's memory allocators.
16222 Without this change, the gnutls library would invoke malloc etc.
16223 directly, which causes problems on non-SYNC_INPUT hosts, and which
16224 runs afoul of improving memory_full behavior. (Bug#8761)
16225 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16226 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16227 xfree instead of the default malloc, realloc, free.
16228 (Fgnutls_boot): No need to check for memory allocation failure,
16229 since xmalloc does that for us.
16231 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
16232 * category.c (hash_get_category_set):
16233 * ccl.c (ccl_driver):
16234 * charset.c (Fdefine_charset_internal):
16235 * charset.h (struct charset.hash_index):

16245 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
16246 (Fsxhash, Fgethash, Fputhash, Fmaphash):
16247 * image.c (make_image, search_image_cache, lookup_image)
16248 (xpm_put_color_table_h):
16249 * lisp.h (struct Lisp_Hash_Table):
16250 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
16251 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
16252 for hashes and hash indexes, instead of 'unsigned' and 'int'.
16253 * alloc.c (allocate_vectorlike):
16254 Check for overflow in vector size calculations.
16255 * ccl.c (ccl_driver):
16256 Check for overflow when converting EMACS_INT to int.
16257 * fns.c, image.c: Remove unnecessary static decls that would otherwise
16258 need to be updated by these changes.
16259 * fns.c (make_hash_table, maybe_resize_hash_table):
16260 Check for integer overflow with large hash tables.
16261 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16262 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16263 (SXHASH_REDUCE): New macro.
16264 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16265 Use it instead of discarding useful hash info with large hash values.
16266 (sxhash_float): New function.
16267 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16268 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16269 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16270 Rewrite to use FIXNUM_BITS, as this simplifies things.
16271 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16272 Adjust signatures to match updated version of code.
16273 (consing_since_gc): Now EMACS_INT, since a single hash table can
16274 use more than INT_MAX bytes.
16276 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
16278 Make it possible to build with GCC-4.6+ -O2 -flto.
16280 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
16282 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
16284 * minibuf.c (get_minibuffer, read_minibuf_unwind):
16285 Call minibuffer-inactive-mode.
16287 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
16289 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
16290 Update dependencies.
16292 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16294 * data.c (init_data): Remove code for UTS, this system is not
16297 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16299 Don't force ./temacs to start in terminal mode.
16301 * frame.c (make_initial_frame): Initialize faces in all cases, not
16302 only when CANNOT_DUMP is defined.
16303 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
16305 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16307 * dispnew.c (add_window_display_history): Use const for the string
16308 pointer. Remove declaration, not needed.
16310 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16312 Use 'inline', not 'INLINE'.
16313 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
16314 * alloc.c, fontset.c (INLINE): Remove.
16315 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
16316 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
16317 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16318 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16319 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16321 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16323 Make it possible to run ./temacs.
16325 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16326 syms_of_callproc does the same thing. Remove test for
16327 "initialized", do it in the caller.
16328 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16330 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16332 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16333 (read_minibuf): Use get_minibuffer.
16334 (syms_of_minibuf): Use DEFSYM.
16335 (Qmetadata): New var.
16336 * data.c (Qbuffer): Don't make it static.
16337 (syms_of_data): Use DEFSYM.
16339 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16341 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16342 (CCL_CODE_MIN): New macro.
16344 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16346 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16348 * eval.c (Qdebug): Now static.
16349 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16350 2011-04-26 change (bzr 104015) that inadvertently undid part of
16351 the 2011-04-14 change (bzr 103913).
16353 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16355 * image.c: Various fixes to ImageMagick code comments.
16356 (Fimagemagick_types): Doc fix.
16358 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16360 Minor fixes prompted by GCC 4.6.0 warnings.
16362 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16364 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16365 (x_clipboard_manager_save_all): Move extern decl to ...
16366 * xterm.h: ... here, so that it can be checked for consistency.
16368 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16370 * xselect.c (x_clipboard_manager_save_frame)
16371 (x_clipboard_manager_save_all): New functions.
16372 (Fx_clipboard_manager_save): Lisp function deleted.
16374 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16375 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16377 * xterm.h: Update prototype.
16379 2011-05-28 William Xu <william.xwl@gmail.com>
16381 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16382 exiting (Bug#8239).
16384 2011-05-28 Jim Meyering <meyering@redhat.com>
16386 Avoid a sign-extension bug in crypto_hash_function.
16387 * fns.c (to_uchar): Define.
16388 (crypto_hash_function): Use it to convert some newly-signed
16389 variables to unsigned, to avoid sign-extension bugs. For example,
16390 without this change, (md5 "truc") would evaluate to
16391 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16392 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16393 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16395 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16397 Integer overflow fixes.
16399 * dbusbind.c: Serial number integer overflow fixes.
16400 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16401 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16402 to hold a serial number that is too large for a fixnum.
16403 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16404 Check for serial numbers out of range. Decode any serial number
16405 that was so large that it became a float. (Bug#8722)
16407 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16408 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16409 Use XFASTINT rather than XUINT when numbers are nonnegative.
16410 (xd_append_arg, Fdbus_method_return_internal):
16411 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16412 arguments, check that Lisp number is nonnegative, rather than
16413 silently wrapping negative numbers around. (Bug#8722)
16414 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16417 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16419 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16421 ccl: Add integer overflow checks.
16422 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16423 (IN_INT_RANGE): New macros.
16424 (ccl_driver): Use them to check for integer overflow when
16425 decoding a CCL program. Many of the new checks are whether XINT (x)
16426 fits in int; it doesn't always, on 64-bit hosts. The new version
16427 doesn't catch all possible integer overflows, but it's an
16428 improvement. (Bug#8719)
16430 * alloc.c (make_event_array): Use XINT, not XUINT.
16431 There's no need for unsigned here.
16433 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16434 This follows up to the 2011-05-06 change that substituted uintptr_t
16435 for EMACS_INT. This case wasn't caught back then.
16437 Rework Fformat to avoid integer overflow issues.
16438 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16439 now (part of C89). Include <verify.h>.
16440 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16441 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16442 (Fformat): Avoid the prepass trying to compute sizes; it was only
16443 approximate and thus did not catch overflow reliably. Instead, walk
16444 through the format just once, formatting and computing sizes as we go,
16445 checking for integer overflow at every step, and allocating a larger
16446 buffer as needed. Keep track separately whether the format is
16447 multibyte. Keep only the most-recently calculated precision, rather
16448 than them all. Record whether each argument has been converted to
16449 string. Use EMACS_INT, not int, for byte and char and arg counts.
16450 Support field widths and precisions larger than INT_MAX. Avoid
16451 sprintf's undefined behavior with conversion specifications such as %#d
16452 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16453 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16454 formatting out-of-range floating point numbers with int
16455 formats. (Bug#8668)
16457 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16459 * data.c: Avoid integer truncation in expressions involving floats.
16460 * data.c: Include <intprops.h>.
16461 (arith_driver): When there's an integer overflow in an expression
16462 involving floating point, convert the integers to floating point
16463 so that the resulting value does not suffer from catastrophic
16464 integer truncation. For example, on a 64-bit host (* 4
16465 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16466 Do not rely on undefined behavior after integer overflow.
16468 merge count_size_as_multibyte, parse_str_to_multibyte
16469 * character.c, character.h (count_size_as_multibyte):
16470 Rename from parse_str_to_multibyte; all uses changed.
16471 Check for integer overflow.
16472 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16473 since it's now a duplicate of the other. This is more of
16474 a character than a buffer op, so better that it's in character.c.
16475 * fns.c, print.c: Adjust to above changes.
16477 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16479 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16481 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16483 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16484 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16485 (x_clipboard_manager_save): Now static.
16486 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16488 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16489 (crypto_hash_function): Now static.
16490 Fix pointer signedness problems. Avoid unnecessary initializations.
16492 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16494 * termhooks.h (Vselection_alist): Make it terminal-local.
16496 * terminal.c (create_terminal): Initialize it.
16498 * xselect.c: Support for clipboard managers.
16499 (Vselection_alist): Move to termhooks.h as terminal-local var.
16500 (LOCAL_SELECTION): New macro.
16501 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16502 (symbol_to_x_atom): Remove gratuitous arg.
16503 (x_handle_selection_request, lisp_data_to_selection_data)
16504 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16505 (x_own_selection, x_get_local_selection, x_convert_selection):
16506 New arg, specifying work frame. Use terminal-local Vselection_alist.
16507 (some_frame_on_display): Delete unused function.
16508 (Fx_own_selection_internal, Fx_get_selection_internal)
16509 (Fx_disown_selection_internal, Fx_selection_owner_p)
16510 (Fx_selection_exists_p): New optional frame arg.
16511 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16512 (x_handle_selection_clear): Don't treat other terminals with the
16513 same keyboard specially. Use the terminal-local Vselection_alist.
16514 (x_clear_frame_selections): Use Frun_hook_with_args.
16516 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16518 * xterm.h: Add support for those atoms.
16520 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16522 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16523 (converted_selections, conversion_fail_tag): New global variables.
16524 (x_selection_request_lisp_error): Free the above.
16525 (x_get_local_selection): Remove unnecessary code.
16526 (x_reply_selection_request): Args changed; handle arbitrary array
16527 of converted selections stored in converted_selections.
16528 Separate the XChangeProperty and SelectionNotify steps.
16529 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16530 (x_convert_selection): New function.
16531 (x_handle_selection_event): Simplify.
16532 (x_get_foreign_selection): Don't ignore incoming requests while
16533 waiting for an answer; this will fail when we implement
16534 SAVE_TARGETS, and seems unnecessary anyway.
16535 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16536 (Vx_sent_selection_functions): Doc fix.
16538 2011-05-26 Leo Liu <sdl.web@gmail.com>
16540 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16542 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16544 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16546 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16547 for fringe update if it has periodic bitmap.
16548 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16549 and fringe_bitmap_periodic_p.
16551 * fringe.c (get_fringe_bitmap_data): New function.
16552 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16553 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16554 row. Mark glyph row for fringe update if periodicity changed.
16556 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16557 for fringe update unless it has periodic bitmap.
16559 2011-05-25 Kenichi Handa <handa@m17n.org>
16561 * xdisp.c (get_next_display_element): Set correct it->face_id for
16562 a static composition.
16564 2011-05-24 Leo Liu <sdl.web@gmail.com>
16567 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16569 * fns.c (crypto_hash_function, Fsha1): New function.
16570 (Fmd5): Use crypto_hash_function.
16571 (syms_of_fns): Add Ssha1.
16573 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16575 * gnutls.c: Remove unused macros.
16576 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16577 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16578 Remove macros that are defined and never used.
16579 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16581 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16583 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16584 (Fx_get_selection_internal): Minor cleanup.
16585 (Fx_own_selection_internal): Rename arguments for consistency with
16588 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16590 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16592 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16594 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16596 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16598 * dispnew.c (scrolling_window): Don't exclude the case that the
16599 last enabled row in the desired matrix touches the bottom boundary.
16601 2011-05-21 Glenn Morris <rgm@gnu.org>
16603 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16604 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16605 and add some more files.
16607 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16609 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16610 report_file_error introduced by the change from 2011-05-07.
16612 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16614 * systime.h (Time): Define only if emacs is defined.
16615 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16616 where the include path doesn't have X11/X.h by default. See
16617 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16619 2011-05-20 Kenichi Handa <handa@m17n.org>
16621 * composite.c (find_automatic_composition): Fix previous change.
16623 2011-05-20 Glenn Morris <rgm@gnu.org>
16625 * lisp.mk: New file, split from Makefile.in.
16626 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16627 (shortlisp): Remove.
16628 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16630 2011-05-19 Glenn Morris <rgm@gnu.org>
16632 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16633 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16634 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16635 (lisp): Set the order to that of loadup.el.
16636 (shortlisp): Make it a copy of $lisp.
16637 (SOME_MACHINE_LISP): Remove.
16638 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16639 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16641 2011-05-18 Kenichi Handa <handa@m17n.org>
16643 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16644 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16645 (find_automatic_composition): Mostly rewrite for efficiency.
16647 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16649 * makefile.w32-in: Update dependencies.
16651 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16653 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16656 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16658 Fix some integer overflow issues, such as string length overflow.
16660 * insdel.c (count_size_as_multibyte): Check for string overflow.
16662 * character.c (lisp_string_width): Check for string overflow.
16663 Use EMACS_INT, not int, for string indexes and lengths; in
16664 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16665 the resulting string length overflows an EMACS_INT; instead,
16666 report a string overflow if no precision given. When checking for
16667 precision exhaustion, use a check that cannot possibly have
16668 integer overflow. (Bug#8675)
16669 * character.h (lisp_string_width): Adjust to new signature.
16671 * alloc.c (string_overflow): New function.
16672 (Fmake_string): Use it. This doesn't change behavior, but saves
16673 a few bytes and will simplify future changes.
16674 * character.c (string_escape_byte8): Likewise.
16675 * lisp.h (string_overflow): New decl.
16677 Fixups, following up to the user-interface timestamp change.
16678 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16679 for UI timestamps, instead of unsigned long.
16680 * msdos.c (mouse_get_pos): Likewise.
16681 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16682 * w32gui.h (Time): Define by including "systime.h" rather than by
16683 declaring it ourselves. (Bug#8664)
16685 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16686 * image.c (clear_image_cache): Likewise.
16688 * term.c (term_mouse_position): Don't assume time_t wraparound.
16690 Be more systematic about user-interface timestamps.
16691 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16692 and sometimes 'EMACS_UINT', to represent these timestamps.
16693 This change causes it to use 'Time' uniformly, as that's what X uses.
16694 This makes the code easier to follow, and makes it easier to catch
16695 integer overflow bugs such as Bug#8664.
16696 * frame.c (Fmouse_position, Fmouse_pixel_position):
16697 Use Time, not unsigned long, for user-interface timestamps.
16698 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16699 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16700 * keyboard.h (last_event_timestamp): Likewise.
16701 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16702 * menu.h (xmenu_show): Likewise.
16703 * term.c (term_mouse_position): Likewise.
16704 * termhooks.h (struct input_event.timestamp): Likewise.
16705 (struct terminal.mouse_position_hook): Likewise.
16706 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16707 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16708 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16709 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16710 what it was before.
16711 * menu.h, termhooks.h: Include "systime.h", for Time.
16713 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16714 Don't assume that the difference between two unsigned long values
16715 can fit into an integer. At this point, we know button_down_time
16716 <= event->timestamp, so the difference must be nonnegative, so
16717 there's no need to cast the result if double-click-time is
16718 nonnegative, as it should be; check that it's nonnegative, just in
16719 case. This bug is triggered when events are more than 2**31 ms
16720 apart (about 25 days). (Bug#8664)
16722 * xselect.c (last_event_timestamp): Remove duplicate decl.
16723 (x_own_selection): Remove needless cast to unsigned long.
16725 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16726 that always fit in int. Use a sentinel instead of a counter, to
16727 avoid a temp and to allay GCC's concerns about possible int overflow.
16728 * frame.h (struct frame): Use int for menu_bar_items_used
16729 instead of EMACS_INT, since it always fits in int.
16731 * menu.c (grow_menu_items): Check for int overflow.
16733 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16735 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16736 Before, the code was not consistent. These values cannot exceed
16737 2**31 - 1 so there's no need to make them unsigned.
16738 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16739 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16740 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16742 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16744 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16745 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16746 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16747 presumably because the widths might not match.
16749 * window.c (size_window): Avoid needless test at loop start.
16751 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16753 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16755 2011-05-12 Drew Adams <drew.adams@oracle.com>
16757 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16759 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16761 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16762 `width' to `bar_area_x' and `bar_area_width', respectively.
16763 (x_scroll_run): Take account of fringe background extension.
16765 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16766 Rename local vars `left' and `width' to `bar_area_x' and
16767 `bar_area_width', respectively.
16768 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16769 background extension.
16771 2011-05-10 Jim Meyering <meyering@redhat.com>
16773 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16775 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16777 * image.c (Finit_image_library): Return t for built-in image types,
16778 like pbm and xbm. (Bug#8640)
16780 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16782 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16784 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16786 * w32console.c (Fset_screen_color): Doc fix.
16787 (Fget_screen_color): New function.
16788 (syms_of_ntterm): Defsubr it.
16790 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16791 unlink the temporary file if Fcall_process didn't create it in the
16793 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16794 child process will be redirected to a file specified with `:file'.
16795 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16796 cue to call_process_cleanup not to close that handle.
16798 2011-05-07 Ben Key <bkey76@gmail.com>
16800 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16801 one of two shell specific rules, either bootstrap-temacs-CMD or
16802 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16803 to the previous implementation of the bootstrap-temacs rule.
16804 The bootstrap-temacs-CMD rule is similar to the previous
16805 implementation of the bootstrap-temacs rule except that it
16806 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16809 These changes, along with some changes to nt/configure.bat,
16810 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16811 earlier fix to add support for --cflags and --ldflags options
16812 that include quotes so that it works whether make uses cmd or
16815 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16817 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16818 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16820 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16821 a string. Handle both cases.
16822 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16823 (Fdbus_register_method): Use Qinvalid_function.
16825 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16827 * makefile.w32-in: Update dependencies.
16828 (LISP_H): Add inttypes.h and stdin.h.
16829 (PROCESS_H): Add unistd.h.
16831 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16833 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16836 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16838 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16840 * term.c (vfatal): Remove stray call to va_end.
16841 It's not needed and the C Standard doesn't allow it here anyway.
16843 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16844 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16846 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16849 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16851 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16853 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16855 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16857 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16859 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16860 * charset.c (Fdefine_charset_internal): Don't initialize
16861 charset.code_space[15]. The value was garbage, on hosts with
16862 32-bit int (Bug#8600).
16864 * lread.c (read_integer): Be more consistent with string-to-number.
16865 Use string_to_number to do the actual conversion; this avoids
16866 rounding errors and fixes some other screwups. Without this fix,
16867 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16868 (digit_to_number): Move earlier, for benefit of read_integer.
16869 Return -1 if the digit is out of range for the base, -2 if it is
16870 not a digit in any supported base. (Bug#8602)
16872 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16874 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16875 to match comment at start of function. This also removes a
16876 GCC warning about overflow in a 32+64-bit port.
16878 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16880 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16881 Reported by Stefan Monnier in
16882 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16883 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16884 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16886 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16887 (EMACS_UINTPTR): Likewise, with uintptr_t.
16889 * lisp.h: Prefer 64-bit EMACS_INT if available.
16890 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16891 on 32-bit hosts that have 64-bit int, so that they can access
16893 However, temporarily disable this change unless the temporary
16894 symbol WIDE_EMACS_INT is defined.
16896 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16898 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16899 This removes an assumption that EMACS_INT and long are the same
16900 width as pointers. The assumption is true for Emacs porting targets
16901 now, but we want to make other targets possible.
16902 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16903 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16904 In the rest of the code, change types of integers that hold casted
16905 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16906 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16907 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16908 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16909 No need to cast type when ORing.
16910 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16911 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16912 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16913 assume EMACS_INT is the same width as char *.
16914 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16915 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16916 Remove no-longer-needed casts.
16917 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16918 (xg_tool_bar_help_callback, xg_make_tool_item):
16919 Use EMACS_INTPTR to hold an integer
16920 that will be cast to void *; this can avoid a GCC warning
16921 if EMACS_INT is not the same width as void *.
16922 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16923 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16924 (current_message_1, set_message_1):
16925 Use a local to convert to proper width without a cast.
16926 * xmenu.c (dialog_selection_callback): Likewise.
16928 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16929 Also, don't assume VALBITS / RAND_BITS is less than 5,
16930 and don't rely on undefined behavior when shifting a 1 left into
16932 * lisp.h (get_random): Change signature to match.
16934 * lread.c (hash_string): Use size_t, not int, for hash computation.
16935 Normally we prefer signed values; but hashing is special, because
16936 it's better to use unsigned division on hash table sizes so that
16937 the remainder is nonnegative. Also, size_t is the natural width
16938 for hashing into memory. The previous code used 'int', which doesn't
16939 retain enough info to hash well into very large tables.
16940 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16942 * dbusbind.c: Don't possibly lose pointer info when converting.
16943 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16944 Use XPNTR rather than XHASH, so that the high-order bits of
16945 the pointer aren't lost when converting through void *.
16947 * eval.c (Fautoload): Don't double-shift a pointer.
16949 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

16983 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16984 Remove unused parameter `fildes'.
16985 * process.c (read_process_output, send_process): Don't pass it.
16987 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16989 Fix previous change: the library cache is defined in w32.c.
16990 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16991 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

17034 instead of gnutls_record_check_pending.
17036 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17038 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17040 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17041 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17044 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17046 * xterm.c (x_set_frame_alpha): Do not set property on anything

17081 (Fcall_process_region): Ditto.
17083 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17085 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17086 rather than `XVECTOR (FOO)->size'.
17088 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17089 inttypes.h, as a gnulib replacement is used if it not available in
17092 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17094 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17095 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17096 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17098 * coding.c (coding_alloc_by_realloc): Error out if destination
17099 will grow beyond MOST_POSITIVE_FIXNUM.
17100 (decode_coding_emacs_mule): Abort if there isn't enough place in
17101 charbuf for the composition carryover bytes. Reserve an extra
17102 space for up to 2 characters produced in a loop.

17117 produced by %s or %c overflows available buffer space. (Bug#8545)
17119 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17121 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

17138 * doprnt.c (doprnt): Don't return value smaller than the buffer
17139 size if the message was truncated. (Bug#8545).
17141 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17143 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

17152 * makefile.w32-in: Update dependencies.
17154 2011-04-27 Eli Zaretskii <eliz@gnu.org>
17156 Improve `doprnt' and its usage. (Bug#8545)
17157 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17158 `format_end'. Remove support for %l as a conversion specifier.
17159 Don't use xrealloc. Improve diagnostics when the %l size modifier
17160 is used. Update the commentary.
17162 * eval.c (verror): Simplify calculation of size_t.
17164 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17167 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17169 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17172 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17174 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17175 This makes this file independent of the recent pseudovector change.
17177 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17179 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17181 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17182 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17183 Remove unused local.
17184 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17186 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17187 GCC 4.6.0 optimizes based on type-based alias analysis.
17188 For example, if b is of type struct buffer * and v of type struct
17189 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17190 != &v->size, and therefore "v->size = 1; b->size = 2; return
17191 v->size;" must therefore return 1. This assumption is incorrect
17192 for Emacs, since it type-puns struct Lisp_Vector * with many other
17193 types. To fix this problem, this patch adds a new type struct
17194 vectorlike_header that documents the constraints on layout of vectors
17195 and pseudovectors, and helps optimizing compilers not get fooled
17196 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17197 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17198 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17200 (XSETPVECTYPE): Rewrite in terms of new macro.
17201 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17202 This is a bit clearer, and further avoids the possibility of
17203 undesirable aliasing.
17204 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17205 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17206 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17207 since Lisp_Subr is a special case (no "next" field).
17208 (ASIZE): Now uses header.size rather than size.
17209 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17210 to avoid the hassle of writing XVECTOR (foo)->header.size.
17211 (struct vectorlike_header): New type.
17212 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17213 object, to help avoid aliasing.
17214 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17215 (SUBRP): Likewise, since Lisp_Subr is a special case.
17216 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17217 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17218 (struct Lisp_Hash_Table): Combine first two members into a single
17219 struct vectorlike_header member. All uses of "size" and "next" members
17220 changed to be "header.size" and "header.next".
17221 * buffer.h (struct buffer): Likewise.
17222 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17223 * frame.h (struct frame): Likewise.
17224 * process.h (struct Lisp_Process): Likewise.
17225 * termhooks.h (struct terminal): Likewise.
17226 * window.c (struct save_window_data, struct saved_window): Likewise.
17227 * window.h (struct window): Likewise.
17228 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17229 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17230 * buffer.c (init_buffer_once): Likewise.
17231 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17233 * process.c (Fformat_network_address): Use local var for size,
17236 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17238 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17239 * data.c (atof): Remove decl; no longer used or needed.
17240 (digit_to_number): Move to lread.c.
17241 (Fstring_to_number): Use new string_to_number function, to be
17242 consistent with how the Lisp reader treats infinities and NaNs.
17243 Do not assume that floating-point numbers represent EMACS_INT
17244 without losing information; this is not true on most 64-bit hosts.
17245 Avoid double-rounding errors, by insisting on integers when
17246 parsing non-base-10 numbers, as the documentation specifies.
17247 * lisp.h (string_to_number): New decl, replacing ...
17248 (isfloat_string): Remove.
17249 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17250 (read1): Do not accept +. and -. as integers; this
17251 appears to have been a coding error. Similarly, do not accept
17252 strings like +-1e0 as floating point numbers. Do not report
17253 overflow for integer overflows unless the base is not 10 which
17254 means we have no simple and reliable way to continue.
17255 Break out the floating-point parsing into a new
17256 function string_to_number, so that Fstring_to_number parses
17257 floating point numbers consistently with the Lisp reader.
17258 (digit_to_number): Move here from data.c. Make it static inline.
17259 (E_CHAR, EXP_INT): Remove, replacing with ...
17260 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17261 (string_to_number): New function, replacing isfloat_string.
17262 This function checks for valid syntax and produces the resulting
17263 Lisp float number too. Rework it so that string-to-number
17264 no longer mishandles examples like "1.0e+". Use strtoumax,
17265 so that overflow for non-base-10 numbers is reported only when
17266 there's no portable and simple way to convert to floating point.
17268 * textprop.c (set_text_properties_1): Rewrite for clarity,
17269 and to avoid GCC warning about integer overflow.
17271 * intervals.h (struct interval): Use EMACS_INT for members
17272 where EMACS_UINT might cause problems. See
17273 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17274 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17275 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17277 (offset_intervals): Tell GCC not to worry about length overflow
17278 when negating a negative length.
17280 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17281 (overrun_check_free): Likewise.
17283 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17284 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17287 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17288 (gnutls_make_error): Rename local to avoid shadowing.
17289 (gnutls_emacs_global_deinit): ifdef out; not used.
17290 (Fgnutls_boot): Use const for pointer to readonly storage.
17291 Comment out unused local. Fix pointer signedness problems.
17293 * lread.c (openp): Don't stuff size_t into an 'int'.
17294 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17295 about possible signed overflow.
17297 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17298 (GDK_KEY_g): Don't define if already defined.
17299 (xg_prepare_tooltip): Avoid pointer signedness problem.
17300 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17302 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17303 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17305 * xfns.c (Fx_window_property): Simplify a bit,
17306 to make a bit faster and to avoid GCC 4.6.0 warning.
17307 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17309 * fns.c (internal_equal): Don't assume size_t fits in int.
17311 * alloc.c (compact_small_strings): Tighten assertion a little.
17313 Replace pEd with more-general pI, and fix some printf arg casts.
17314 * lisp.h (pI): New macro, generalizing old pEd macro to other
17315 conversion specifiers. For example, use "...%"pI"d..." rather
17316 than "...%"pEd"...".
17317 (pEd): Remove. All uses replaced with similar uses of pI.
17318 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17319 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17320 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17321 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17322 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17323 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17324 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17326 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17327 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17328 * print.c (safe_debug_print, print_object): Likewise.
17329 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17331 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17332 avoiding the 0 flag, which is not portable.
17333 * process.c (Fmake_network_process): Use pI to avoid cast.
17334 * region-cache.c (pp_cache): Likewise.
17335 * xdisp.c (decode_mode_spec): Likewise.
17336 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17337 behavior on 64-bit hosts with printf arg.
17338 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17339 (x_stop_queuing_selection_requests): Likewise.
17340 (x_get_window_property): Don't truncate byte count to an 'int'
17343 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17344 here, since it parses constructs like leading '-' and spaces,
17345 which are not wanted; and it overflows with large numbers.
17346 Instead, simply match F[0-9]+, which is what is wanted anyway.
17348 * alloc.c: Remove unportable assumptions about struct layout.
17349 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17350 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17351 (allocate_vectorlike, make_pure_vector): Use the new macros,
17352 plus offsetof, to remove unportable assumptions about struct layout.
17353 These assumptions hold on all porting targets that I know of, but
17354 they are not guaranteed, they're easy to remove, and removing them
17355 makes further changes easier.
17357 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17358 This doesn't fix a bug but makes the code clearer.
17359 (string_overrun_cookie): Now const. Use initializers that
17360 don't formally overflow signed char, to avoid warnings.
17361 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17362 can cause Emacs to crash when string overrun checking is enabled.
17363 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17364 multiple of sizeof (EMACS_INT); it need not be, if
17365 alignof(EMACS_INT) < sizeof (EMACS_INT).
17366 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

17397 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17398 "cast to pointer from integer of different size".

17401 * doprnt.c (doprnt): Document the set of format control sequences
17402 supported by the function. Use SAFE_ALLOCA instead of always
17405 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17406 is one byte too soon. Don't use xrealloc; instead xfree and

17418 docstring. Start callback support.
17419 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17420 unless a fatal error occurred. Call gnutls_alert_send_appropriate

17524 codepoint of an invalid character, to avoid displaying a bogus
17527 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
17528 `error', not SYMBOL_NAME itself.
17530 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
17531 character arguments to `error'.
17533 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17534 to `error' in error message about FINAL_CHAR argument. Make sure
17535 FINAL_CHAR is a character, and use %c when it is passed as
17536 argument to `error'.
17538 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17540 * s/ms-w32.h (localtime): Redirect to sys_localtime.
17542 * w32.c: Include <time.h>.

17606 * dispextern.h (struct redisplay_interface): Rename param
17607 to avoid shadowing.
17608 * termhooks.h (struct terminal): Likewise.

17725 * nsfont.m: Fixed bugs in ns_get_family and
17726 ns_descriptor_to_entity that were caused by using free to
17727 deallocate memory blocks that were allocated by xmalloc (via
17728 xstrdup). This caused Emacs to crash when compiled with
17729 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
17730 --enable-checking=xmallocoverrun). xfree is now used to
17731 deallocate these memory blocks.

17747 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
17748 (emacs_read, emacs_write): Use it.
17749 * process.c (send_process): Adjust to the new signatures of
17750 emacs_write and emacs_gnutls_write. Do not attempt to store
17751 a byte offset into an 'int'; it might overflow.

18229 is outside the buffer's accessible region. (Bug#8468)
18231 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18233 Fix write-region and its subroutines for buffers > 2GB.
18234 * fileio.c (a_write, e_write): Modify declaration of arguments and
18235 local variables to support buffers larger than 2GB.
18236 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18238 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18239 argument, local variables, and return value.
18241 * lisp.h: Update prototypes of emacs_write and emacs_read.
18243 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18245 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18247 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18249 Fix more problems found by GCC 4.6.0's static checks.
18251 * xdisp.c (vmessage): Use a better test for character truncation.
18253 * charset.c (load_charset_map): <, not <=, for optimization,
18254 and to avoid potential problems with integer overflow.
18255 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18256 * casetab.c (set_identity, shuffle): Likewise.
18257 * editfns.c (Fformat): Likewise.
18258 * syntax.c (skip_chars): Likewise.
18260 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18261 This also lets GCC 4.6.0 generate slightly better loop code.
18263 * callint.c (Fcall_interactively): <, not <=, for optimization.
18264 (Fcall_interactively): Count the number of arguments produced,
18265 not the number of arguments given. This is simpler and lets GCC
18266 4.6.0 generate slightly better code.
18268 * ftfont.c: Distingish more carefully between FcChar8 and char.
18269 The previous code passed unsigned char * to a functions like
18270 strlen and xstrcasecmp that expect char *, which does not
18271 conform to the C standard.
18272 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18273 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18274 char * when the C standard requires it.
18276 * keyboard.c (read_char): Remove unused var.
18278 * eval.c: Port to Windows vsnprintf (Bug#8435).
18279 Include <limits.h>.
18280 (SIZE_MAX): Define if the headers do not.
18281 (verror): Do not give up if vsnprintf returns a negative count.
18282 Instead, grow the buffer. This ports to Windows vsnprintf, which
18283 does not conform to C99. Problem reported by Eli Zaretskii.
18284 Also, simplify the allocation scheme, by avoiding the need for
18285 calling realloc, and removing the ALLOCATED variable.
18287 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18289 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18290 But keep the doprint source code for now, as we might revamp it
18291 and use it again (Bug#8435).
18292 * lisp.h (doprnt): Remove.
18293 * Makefile.in (base_obj): Remove doprnt.o.
18294 * deps.mk (doprnt.o): Remove.
18296 error: Print 32- and 64-bit integers portably (Bug#8435).
18297 Without this change, on typical 64-bit hosts error ("...%d...", N)
18298 was used to print both 32- and 64-bit integers N, which relied on
18299 undefined behavior.
18300 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18301 * lisp.h (error, verror): Mark as printf-like functions.
18302 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18303 Report overflow in size calculations when allocating printf buffer.
18304 Do not truncate output string at its first null byte.
18305 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18306 Truncate the output at a character boundary, since vsnprintf does not
18308 * charset.c (check_iso_charset_parameter): Convert internal
18309 character to string before calling 'error', since %c now has the
18311 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18312 overflow when computing char to be passed to 'error'. Do not
18313 pass Lisp_Object to 'error'; pass the integer instead.
18314 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18315 formatted with plain %d.
18317 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18319 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18321 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18323 * xterm.c (x_catch_errors): Remove duplicate declaration.
18325 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18327 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18329 2011-04-10 Jim Meyering <meyering@redhat.com>
18331 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18332 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18333 return ssize_t not "int", and use size_t as the buffer length.
18334 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18335 * gnutls.h: Update declarations.
18336 * process.c (read_process_output): Use ssize_t, to match.
18337 (send_process): Likewise.
18339 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18341 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18343 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18345 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18346 Use unsigned char, to match FcChar8 type definition.
18348 * xterm.c (handle_one_xevent):
18349 * xmenu.c (create_and_show_popup_menu):
18350 * xselect.c (x_decline_selection_request)
18351 (x_reply_selection_request): Avoid type-punned deref of X events.
18353 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18355 Fix some uses of `int' instead of EMACS_INT.
18356 * search.c (string_match_1, fast_string_match)
18357 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18358 (scan_buffer, find_next_newline_no_quit)
18359 (find_before_next_newline, search_command, Freplace_match)
18360 (Fmatch_data): Make some `int' variables be EMACS_INT.
18362 * xdisp.c (display_count_lines): 3rd argument and return value now
18363 EMACS_INT. All callers changed.
18364 (pint2hrstr): Last argument is now EMACS_INT.
18366 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18367 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18368 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18369 (decode_coding_utf_16, decode_coding_emacs_mule)
18370 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
18371 (decode_coding_ccl, decode_coding_charset)
18372 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18373 (decode_coding_iso_2022, decode_coding_emacs_mule)
18374 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18375 <char_offset, last_offset>: Declare EMACS_INT.
18376 (encode_coding_utf_8, encode_coding_utf_16)
18377 (encode_coding_emacs_mule, encode_invocation_designation)
18378 (encode_designation_at_bol, encode_coding_iso_2022)
18379 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18380 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18382 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18383 (encode_invocation_designation): Last argument P_NCHARS is now
18385 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18386 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18388 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18391 * ccl.c (Fccl_execute_on_string): Declare some variables
18394 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18396 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18398 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18400 * process.c (Fformat_network_address): Doc fix.
18402 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18404 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18406 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18408 * keyboard.c (read_char): Call Lisp function help-form-show,
18409 instead of using internal_with_output_to_temp_buffer.
18410 (Qhelp_form_show): New var.
18411 (syms_of_keyboard): Use DEFSYM macro.
18413 * print.c (internal_with_output_to_temp_buffer): Function deleted.
18415 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
18417 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18419 * process.c (Flist_processes): Remove to Lisp.
18420 (list_processes_1): Delete.

18426 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18428 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18430 Fix more problems found by GCC 4.6.0's static checks.

18434 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18436 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18438 * xdisp.c (vmessage): Mark as a printf-like function.
18440 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18442 * sound.c (sound_warning): Don't crash if arg contains a printf format.

18447 to system-supplied API.
18449 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18451 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18452 This avoids several warnings with gcc -Wstrict-overflow.
18453 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18454 directly, rather than having caller test rule sign. This avoids
18455 some unnecessary tests.
18456 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18457 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18458 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18460 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18461 (xfont_open): Avoid unnecessary tests.
18463 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18465 * composite.h, composite.c (composition_gstring_put_cache):
18466 Use EMACS_INT, not int, for length.

18469 breaking out part of COMPOSITION_DECODE_RULE.
18470 (COMPOSITION_DECODE_RULE): Use it.
18471 * composite.c (get_composition_id): Remove unused local vars,
18472 by using the new macro.
18474 * textprop.c (set_text_properties_1): Change while to do-while,
18475 since the condition is always true at first.
18477 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18478 (interval_deletion_adjustment): Return unsigned value.
18481 * process.c (list_processes_1, create_pty, read_process_output):

18493 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18494 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18495 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18497 * print.c (print_error_message): Avoid int overflow.
18499 * font.c (font_list_entities): Redo for clarity,
18500 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18502 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18503 (font_score): Avoid potential overflow in diff calculation.
18505 * fns.c (substring_both): Remove var that is set but not used.
18506 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18508 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18510 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18511 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18512 can always succeed if overflow has undefined behavior.
18514 * search.c (boyer_moore, wordify): Remove vars set but not used.
18515 (wordify): Omit three unnecessary tests.
18517 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18518 All callers changed. This avoids the need for an unused var.
18520 * casefiddle.c (casify_region): Remove var that is set but not used.
18522 * dired.c (file_name_completion): Remove var that is set but not used.
18524 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18526 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18527 (Finsert_file_contents): Remove unnecessary code checking fd.
18529 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18530 Check for integer overflow on size calculations.
18532 * buffer.c (Fprevious_overlay_change): Remove var that is set
18535 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18536 Remove vars that are set but not used.
18537 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18538 (timer_check_2): Mark vars as initialized.
18540 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18542 * image.c (lookup_image): Remove var that is set but not used.
18543 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18545 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18546 that are set but not used.
18548 * xfns.c (make_invisible_cursor): Don't return garbage
18549 if XCreateBitmapFromData fails (Bug#8410).
18551 * xselect.c (x_get_local_selection, x_handle_property_notify):
18552 Remove vars that are set but not used.

18569 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18570 All callers changed.

18572 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18573 (decode_coding_charset): Remove vars that are set but not used.
18575 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18576 that is set but not used.
18578 * print.c (print_object): Remove var that is set but not used.
18580 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18581 The gnulib version avoids calling malloc in the usual case,
18582 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18583 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18584 * filelock.c (current_lock_owner): Likewise.
18585 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

18588 (emacs_readlink): New function.
18589 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18590 ../lib/careadlinkat.h.
18592 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18594 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18595 first non-nil return value).

18609 unused at least since Kim's GUI unification at revno:50135 (2003-03-16)
18610 and thereabouts. All callers changed.
18611 (get_per_char_metric): Remove parameter `f', unused since
18612 revno:87605 (2008-05-14). All callers changed.

18616 do not dereference NULL upon failed strdup
18617 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.

18694 (try_scrolling): Use it when setting scroll_limit.
18695 Limit scrolling to 100 screen lines.
18696 (redisplay_window): Even when falling back on "recentering",
18697 position point in the window according to scroll-conservatively,
18698 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18700 (try_scrolling): When point is above the window, allow searching
18701 as far as scroll_max, or one screenful, to compute vertical
18702 distance from PT to the scroll margin position. This prevents
18703 try_scrolling from unnecessarily failing when
18704 scroll-conservatively is set to a value slightly larger than the
18705 window height. Clean up the case of PT below the margin at bottom
18706 of window: scroll_max can no longer be INT_MAX. When aggressive
18707 scrolling is in use, don't let point enter the opposite scroll
18708 margin as result of the scroll.
18709 (syms_of_xdisp) <scroll-conservatively>: Document the
18710 threshold of 100 lines for never-recentering scrolling.
18712 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18714 * dispextern.h (move_it_by_lines):
18715 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
18716 since revno:34925 (2000-12-29). All callers changed.
18717 (message_log_check_duplicate): Remove parameters `prev_bol' and
18718 `this_bol', unused since revno:20537 (1998-01-01). All callers changed.
18719 (redisplay_internal): Remove parameter `preserve_echo_area',
18720 unused since revno:25013 (1999-07-21). All callers changed.
18722 * indent.c (Fvertical_motion):
18723 * window.c (window_scroll_pixel_based, Frecenter):
18724 Don't pass `need_y_p' to `move_it_by_lines'.
18726 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18728 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18729 steal a few bits to be more compact.
18730 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18731 Remove unneeded casts.
18733 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18735 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18737 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18738 binding" message (bug#7967).
18740 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18742 Fix more problems found by GCC 4.6.0's static checks.
18744 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18745 Remove unused local var.
18747 * editfns.c (Fmessage_box): Remove unused local var.
18749 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18750 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18751 Omit unused local vars.
18752 * window.c (shrink_windows): Omit unused local var.
18753 * menu.c (digest_single_submenu): Omit unused local var.
18754 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18755 Omit unused local var.
18757 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18758 Don't assume string length fits in int.
18759 (keyremap_step, read_key_sequence): Use size_t for sizes.
18760 (read_key_sequence): Don't check last_real_key_start redundantly.
18762 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18763 instead of alloca (Bug#8344).
18765 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18766 (Fbacktrace_frame): Don't assume nframes fits in int.
18768 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18770 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18773 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18775 * cm.c (calccost): Turn while-do into do-while, for clarity.
18777 * keyboard.c (syms_of_keyboard): Use the same style as later
18778 in this function when indexing through an array. This also
18779 works around GCC bug 48267.
18781 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18783 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18785 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18786 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18788 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18789 This avoids undefined behavior on integer overflow, and is a bit
18790 more convenient anyway since it is compared to a size_t variable.
18792 Variadic C functions now count arguments with size_t, not int.
18793 This avoids an unnecessary limitation on 64-bit machines, which
18794 caused (substring ...) to crash on large vectors (Bug#8344).
18795 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18796 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
18797 All variadic functions and their callers changed accordingly.
18798 (struct gcpro.nvars): Now size_t, not int. All uses changed.
18799 * data.c (arith_driver, float_arith_driver): Likewise.
18800 * editfns.c (general_insert_function): Likewise.
18801 * eval.c (struct backtrace.nargs, interactive_p)

18803 (funcall_lambda, mark_backtrace): Likewise.
18804 * fns.c (concat): Likewise.
18805 * frame.c (x_set_frame_parameters): Likewise.
18806 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18807 0 if not found, not -1. All callers changed.
18809 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18810 (stack_copy_size): Now size_t, not int.
18811 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
18813 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18815 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
18816 unused since revno:43563.1.17 (2002-03-01) and revno:84043 (2008-02-1).
18817 All callers changed.
18819 * lisp.h (multibyte_char_to_unibyte):
18820 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18821 unused since revno:43563.1.16 (2002-03-01) and revno:84043 (2008-02-1).
18822 * character.h (CHAR_TO_BYTE8):
18823 * cmds.c (internal_self_insert):
18824 * editfns.c (general_insert_function):
18825 * keymap.c (push_key_description):
18826 * search.c (Freplace_match):
18827 * xdisp.c (message_dolog, set_message_1): All callers changed.
18829 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18831 * keyboard.c (safe_run_hook_funcall): New function.
18832 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18833 don't set the hook to nil, but remove the offending function instead.
18834 (Qcommand_hook_internal): Remove, unused.
18835 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18836 Vcommand_hook_internal.
18838 * eval.c (enum run_hooks_condition): Remove.
18839 (funcall_nil, funcall_not): New functions.
18840 (run_hook_with_args): Call each function through a `funcall' argument.
18841 Remove `cond' argument, now redundant.
18842 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
18843 (Frun_hook_with_args_until_failure): Adjust accordingly.
18844 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
18846 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18848 * dispextern.h (string_buffer_position): Remove declaration.
18850 * print.c (strout): Remove parameter `multibyte', unused since
18851 revno:25356 (1999-08-21). All callers changed.
18853 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18854 never used since function introduction in revno:20870 (1998-02-08).
18855 All callers changed.
18857 * w32.c (_wsa_errlist): Use braces for struct initializers.
18859 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
18860 never used since function introduction in revno:36704 (2001-03-09).
18861 All callers changed.
18862 (string_buffer_position): Likewise. Also, make static (it's never
18863 used outside xdisp.c).
18864 (cursor_row_p): Remove parameter `w', unused since
18865 revno:32591 (2000-10-17). All callers changed.
18866 (decode_mode_spec): Remove parameter `precision', introduced during
18867 Gerd Moellmann's rewrite at revno:25013 (1999-07-21), but never used.
18868 All callers changed.

18876 * nsterm.m (ns_menu_bar_is_hidden): New variable.
18877 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
18878 (ns_update_auto_hide_menu_bar): New functions.
18879 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

18881 ns_constrain_all_frames.
18882 (constrainFrameRect): Return at once if ns_menu_bar_should_be_hidden.
18883 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.

18889 2011-03-27 Glenn Morris <rgm@gnu.org>
18891 * syssignal.h: Replace RETSIGTYPE with void.
18892 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
18893 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
18894 Replace SIGTYPE with void everywhere.
18895 * s/usg5-4-common.h (SIGTYPE): Remove definition.

18901 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18903 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18905 * w32.c (read_unc_volume): Use parameter `henum', instead of
18906 global variable `wget_enum_handle'.
18908 * keymap.c (describe_vector): Remove parameters `indices' and
18909 `char_table_depth', unused since revno:43563.1.32 (2002-03-01).

18916 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
18917 unused since revno:86854 (2008-04-19).
18919 * keyboard.c (read_char):
18920 * w32menu.c (w32_menu_display_help):
18921 * xmenu.c (show_help_event, menu_help_callback):
18922 Adjust calls to `show_help_echo'.
18924 * gtkutil.c (xg_maybe_add_timer):
18925 * keyboard.c (readable_events):
18926 * process.c (wait_reading_process_output):
18927 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18929 * insdel.c (adjust_markers_gap_motion):
18930 Remove; no-op since revno:20569 (1998-01-02).
18931 (gap_left, gap_right): Don't call it.
18933 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
18935 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
18936 incurred during fontification.

19004 2011-03-23 Julien Danjou <julien@danjou.info>
19006 * term.c (Fsuspend_tty, Fresume_tty):
19007 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
19008 * window.c (temp_output_buffer_show):
19009 * insdel.c (signal_before_change):
19010 * frame.c (Fhandle_switch_frame):

19015 * callint.c (Fcall_interactively):
19016 * buffer.c (Fkill_all_local_variables):
19017 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19019 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19020 unconditionally since it does the check itself.
19022 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19024 Fix more problems found by GCC 4.5.2's static checks.
19026 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19027 the first time through the loop, since we know p0 < p1 then.
19028 This also avoids a gcc -Wstrict-overflow warning.
19030 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19031 leading to a memory leak, possible in functions like
19032 load_charset_map_from_file that can allocate an unbounded number
19033 of objects (Bug#8318).
19035 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19036 that could (at least in theory) be that large.
19038 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19039 This is less likely to overflow, and avoids undefined behavior if
19040 overflow does occur. All callers changed. Use strtoul to scan
19041 for the unsigned long integer.
19042 (pint2hrstr): Simplify and tune code slightly.
19043 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
19045 * scroll.c (do_scrolling): Work around GCC bug 48228.
19046 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
19048 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
19049 This also avoids a warning with gcc -Wstrict-overflow.
19050 (validate_x_resource_name): Simplify count usage.
19051 This also avoids a warning with gcc -Wstrict-overflow.
19053 * fileio.c (Fcopy_file): Report error if fchown or fchmod
19056 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
19058 * process.c (Fmake_network_process): Use socklen_t, not int,
19059 where POSIX says socklen_t is required in portable programs.
19060 This fixes a porting bug on hosts like 64-bit HP-UX, where
19061 socklen_t is wider than int (Bug#8277).
19062 (Fmake_network_process, server_accept_connection):
19063 (wait_reading_process_output, read_process_output):
19066 * process.c: Rename or move locals to avoid shadowing.

19070 (Fmake_network_process): Define label "retry_connect" only if needed.
19071 (Fnetwork_interface_info): Fix pointer signedness.
19072 (process_send_signal): Add cast to avoid pointer signedness problem.
19073 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
19074 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
19076 Make tparam.h and terminfo.c consistent.
19077 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19078 Include tparam.h instead, since it declares them.
19079 * cm.h (PC): Remove extern decl; tparam.h now does this.
19080 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19081 * terminfo.c: Include tparam.h, to check interfaces.
19082 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19083 (tparam): Adjust signature to match interface in tparam.h;
19084 this removes some undefined behavior. Check that outstring and len
19085 are zero, which they always are with Emacs.
19086 * tparam.h (PC, BC, UP): New extern decls.
19088 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19089 (xftfont_open): Rename locals to avoid shadowing.
19091 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
19092 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
19093 (OTF_TAG_SYM): Omit macro if not needed.
19094 (ftfont_list): Remove unused local.
19095 (get_adstyle_property, ftfont_pattern_entity):
19096 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
19097 Rename locals to avoid shadowing.
19099 * xfont.c (xfont_list_family): Mark var as initialized.
19101 * xml.c (make_dom): Now static.
19103 * composite.c (composition_compute_stop_pos): Rename local to
19105 (composition_reseat_it): Remove unused locals.
19106 (find_automatic_composition, composition_adjust_point): Likewise.
19107 (composition_update_it): Mark var as initialized.
19108 (find_automatic_composition): Mark vars as initialized,
19109 with a FIXME (Bug#8290).
19111 character.h: Rename locals to avoid shadowing.
19112 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
19113 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
19114 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
19115 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19116 to avoid shadowing.
19118 * textprop.c (property_change_between_p): Remove; unused.
19120 * intervals.c (interval_start_pos): Now static.
19122 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
19124 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
19125 Rename locals to avoid shadowing.
19127 * sound.c (wav_play, au_play, Fplay_sound_internal):
19128 Fix pointer signedness.
19129 (alsa_choose_format): Remove unused local var.
19130 (wav_play): Initialize a variable to 0, to prevent undefined

19138 clobbering (Bug#8298).
19139 * sysdep.c (sys_subshell): Likewise.
19140 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19142 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19143 This should get cleaned up, so that child_setup has the
19144 same signature on all platforms.
19146 * callproc.c (call_process_cleanup): Now static.
19147 (relocate_fd): Rename locals to avoid shadowing.
19149 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

19278 some of which prompt warnings from gcc -Wbad-function-cast.
19279 (Fformat_time_string, Fencode_time, Finsert_char):

19308 (Fmemory_limit): Cast sbrk's returned value to char *.
19310 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

19313 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
19315 Use functions, not macros, for up- and down-casing (Bug#8254).
19316 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19317 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
19318 to use the following functions instead of these macros.
19319 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19320 EMACS_INT, since callers assume the returned value fits in int.
19321 (upcase1): Likewise, for UPCASE_TABLE.
19322 (uppercasep, lowercasep, upcase): New static inline functions.
19323 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

19333 (regex_compile, re_match_2_internal): Mark locals as initialized.
19334 (RETALLOC_IF): Define only if needed.
19335 (WORDCHAR_P): Likewise. This one is never needed, but is used
19336 only in a comment talking about a compiler bug, so put inside
19337 the #if 0 of that comment.
19338 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19339 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

19365 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
19366 New macros, so that the caller can use some names other than
19367 gcpro1, gcpro2, etc.
19368 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19370 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19371 argument, for consistency with GCPRO2_VAR, etc: it is now the
19372 prefix of the variable, not the variable itself. All uses
19374 * dired.c (directory_files_internal, file_name_completion):
19375 Rename locals to avoid shadowing.
19377 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19378 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19379 dired.c's scmp function, had undefined behavior.
19380 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19381 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19382 * buffer.h: ... to here, because these macros use current_buffer,
19383 and the new implementation with inline functions needs to have
19384 current_buffer in scope now, rather than later when the macros
19386 (downcase, upcase1): New static inline functions.
19387 (DOWNCASE, UPCASE1): Reimplement using these functions.
19388 This avoids undefined behavior in expressions like
19389 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19390 from race conditions in accessing the global variables
19391 case_temp1 and case_temp2.
19392 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19393 * lisp.h (case_temp1, case_temp2): Remove their decls.
19394 * character.h (ASCII_CHAR_P): Move from here ...
19395 * lisp.h: ... to here, so that the inline functions mentioned
19396 above can use them.
19398 * dired.c (directory_files_internal_unwind): Now static.
19400 * fileio.c (file_name_as_directory, directory_file_name):

19403 (file_name_as_directory): Use const pointers when appropriate.
19404 (Fexpand_file_name): Likewise. In particular, newdir might
19405 point at constant storage, so make it a const pointer.
19406 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
19407 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19409 (Fset_file_times, Finsert_file_contents, auto_save_error):

19414 to avoid shadowing.
19416 * marker.c (bytepos_to_charpos): Remove; unused.
19418 * lisp.h (verify_bytepos, count_markers): New decls,
19419 so that gcc does not warn that these functions aren't declared.
19421 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
19422 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19423 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19424 (copy_text): Remove unused local var.
19426 * filelock.c (within_one_second): Now static.
19427 (lock_file_1): Rename local to avoid shadowing.
19429 * buffer.c (fix_overlays_before): Mark locals as initialized.
19430 (fix_start_end_in_overlays): Likewise. This function should be
19431 simplified by using pointers-to-pointers, but that's a different
19433 (switch_to_buffer_1): Now static.
19434 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19435 (report_overlay_modification): Rename locals to avoid shadowing.
19437 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
19438 Fix pointer signedness issue.
19439 (sys_subshell): Mark local as volatile if checking for lint,
19440 to suppress a gcc -Wclobbered warning that does not seem to be right.
19441 (MAXPATHLEN): Define only if needed.
19443 * process.c (serial_open, serial_configure): Move decls from here ...
19444 * systty.h: ... to here, so that they can be checked.
19446 * fns.c (get_random, seed_random): Move extern decls from here ...
19447 * lisp.h: ... to here, so that they can be checked.
19449 * sysdep.c (reset_io): Now static.
19450 (wait_for_termination_signal): Remove; unused.
19452 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

19455 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
19456 (DENSE_TABLE_SIZE): Remove; unused.
19457 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
19458 (describe_map_tree):
19459 Rename locals to avoid shadowing.
19461 * keyboard.c: Declare functions static if they are not used elsewhere.
