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

695 called when Vload_path is already set up.
697 * w32.h (check_windows_init_file): Add prototype.
699 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

706 installation tree, as appropriate.
708 * callproc.c (init_callproc_1): Call decode_env_path instead of
709 doing its equivalent by hand.

743 Remove unnecessary pointer casts.
744 * alloc.c (record_xmalloc): New function.
745 * lisp.h (record_xmalloc): New decl.
746 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
747 more like a function. This is because the pointer cast is not
748 needed. All uses changed.
749 * print.c (print_string, print_error_message): Avoid length recalc.
751 Improve fix for macroexp crash with debugging (Bug#12118).
752 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
753 ARRAY_MARK_FLAG when checking subscripts, because ASET is
754 not supposed to be invoked from the garbage collector.
755 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.

773 headers (most versions of MinGW w32api don't).
774 (get_security_info, create_symbolic_link)
775 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
777 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

788 handle, not by name. Produce S_IFLNK bit for symlinks, when
790 (stat, lstat): New functions, call 'stat_worker'.
791 (symlink, readlink, careadlinkat): Rewritten to create and resolve
792 symlinks when the underlying filesystem supports them.

796 Fix macroexp crash on Windows with debugging (Bug#12118).
797 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
798 checking subscripts; problem introduced with the recent
799 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
800 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
801 since it's used in non-static inline functions now.
803 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
804 Don't assume buffer size fits in 'int'. Remove unused local.
806 Use C99-style 'extern inline' if available.

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

853 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
855 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
856 This how ASET and AREF are supposed to work, and makes
857 it easier to think about future improvements. See
858 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
859 * charset.h (set_charset_attr): New function.

1351 the fix for 12036 would have avoided some of the problems noted in
1352 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
1353 would have been more obvious.

1365 not be usable in #if. This simplifies things.
1367 2012-07-26 Juanma Barranquero <lekktu@gmail.com>

1377 Adjust to changes in lisp.h and emacs.c, by using
1378 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1379 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1380 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1381 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS

1387 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1388 (xreload, hook-run, hookpost-run): Remove.

1421 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1422 than macros. This simplifies debugging in the usual case, since
1423 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1424 and it allows expressions involving EMACS_INT casts.
1425 * .gdbinit (xreload): Simplify by using EMACS_INT cast.

1480 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1481 This avoids crash reported by Christoph Scholtes at
1482 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1484 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>

2290 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2291 * nsterm.m (ns_term_init):
2292 Avoid the need for strncpy, by using build_string or
2293 make_unibyte_string directly. Use dtoastr, not snprintf.
2294 * process.c (Fmake_network_process): Diagnose service names that
2295 are too long, rather than silently truncating them or creating
2296 non-null-terminated names.
2297 (Fnetwork_interface_info): Likewise, for interface names.
2298 * sysdep.c (system_process_attributes) [GNU_LINUX]:
2299 Prefer sprintf to strncat.
2300 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

2326 Optimize pure C strings initialization.
2327 * lisp.h (make_pure_string): Fix prototype.
2328 (build_pure_c_string): New function, defined as static inline. This
2329 provides a better opportunity to optimize away calls to strlen when
2330 the function is called with compile-time constant argument.
2331 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2332 argument, adjust users accordingly. Use build_pure_c_string where
2334 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2335 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
2336 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
2338 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2340 Avoid calls to strlen in miscellaneous functions.
2341 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
2342 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
2343 * lread.c (openp): Likewise.

2347 Avoid calls to strlen in path processing functions.
2348 * fileio.c (file_name_as_directory): Add comment. Change to add
2349 srclen argument and return the length of result. Adjust users

2353 Adjust users accordingly.
2354 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2356 2012-07-10 Glenn Morris <rgm@gnu.org>

2363 * s/gnu.h (DATA_START): Move definitions to configure.
2365 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2366 We include usg5-4-common.h, which defines them both.
2368 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2369 O_RDONLY already includes it).
2371 Stop ns builds setting the EMACSLOADPATH environment variable.
2372 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2373 Now it does not set EMACSLOADPATH, just returns the load-path string.
2374 * nsterm.h: Update accordingly.
2375 * lread.c [HAVE_NS]: Include nsterm.h.
2376 (init_lread) [HAVE_NS]: Use ns_load_path.

2379 2012-07-09 Glenn Morris <rgm@gnu.org>
2381 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2382 since the included bsd-common.h does so.
2384 Stop ns builds setting the EMACSPATH environment variable.
2385 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2386 (ns_init_paths): Do not set EMACSPATH.
2387 * nsterm.h (ns_exec_path): Add it.
2388 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2391 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2393 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2395 * process.c (wait_reading_process_output): 'waitchannels' was unset
2396 when read_kbd || !NILP (wait_for_cell); fix this.
2398 Add GCC-style 'const' attribute to functions that can use it.
2399 * character.h (char_resolve_modifier_mask):
2400 * keyboard.h (make_ctrl_char):
2401 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

2408 Declare the dummy function with ATTRIBUTE_CONST.
2409 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2410 Add decls with ATTRIBUTE_CONST.
2412 Minor improvements to make_formatted_string.
2413 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2414 where int is good enough, as vsprintf returns an int.
2415 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2417 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2419 Use make_formatted_string to avoid double length calculation.

2444 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2446 Move marker debugging code under MARKER_DEBUG.
2447 * marker.c (MARKER_DEBUG): Move marker debugging code under
2448 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2449 for bootstrap with --enable-checking (~3x slowdown reported
2450 by Juanma Barranquero <lekktu@gmail.com>).
2451 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2453 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2455 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2456 See <http://bugs.gnu.org/11825#29>.
2458 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2460 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2461 has no font, use the frame's font. (Bug#11813)
2462 (display_line): Add commentary about displaying truncation glyphs
2464 (produce_special_glyphs): Move here from term.c.
2466 * term.c (produce_special_glyphs): Move to xdisp.c.
2468 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2471 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2473 * xdisp.c (display_line): Avoid warning about implicit declaration
2476 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2478 * lisp.h: Remove empty conditional.
2480 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2482 * lread.c (load_path_check): Now static.
2484 Fix some minor --with-ns problems found by static checking.
2485 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2486 (x_set_font) [!HAVE_X_WINDOWS]:
2487 * image.c (xpm_load_image) [HAVE_NS]:
2488 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2489 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2490 Remove unused local.
2491 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2492 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2493 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2494 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2495 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2496 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2497 Fix pointer signedness problem.
2498 * xfaces.c (FRAME_X_FONT_TABLE):
2499 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2501 2012-07-07 Glenn Morris <rgm@gnu.org>
2503 * lread.c (load_path_check): New function, split from init_lread.
2504 (init_lread): Reorganize. Motivation:
2505 If EMACSLOADPATH is set, check/warn about that rather than the
2506 defaults, which we are not going to use. Hence we can remove
2507 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2508 Don't warn if site-lisp directories are missing.
2509 If not installed, start from a blank load-path, since
2510 PATH_LOADSEARCH refers to the eventual installation directories.
2512 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2514 Support truncation and continuation glyphs on GUI frames, when
2515 fringes are disabled. (Bug#11832)
2516 * xdisp.c (init_iterator): Get dimensions of truncation and
2517 continuation glyphs even if on GUI frames.
2518 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2519 or both, are absent.
2520 (start_display, move_it_in_display_line_to): Handle the case of a
2521 GUI frame without a fringe to display continuation or truncation
2523 (insert_left_trunc_glyphs): Support GUI frames: make sure
2524 truncation glyphs overwrite enough glyphs from the current line to
2525 have sufficient space in pixels.
2526 (display_line): Support truncation and continuation glyphs on GUI
2527 frames. If some spare pixels are left on the line after inserting
2528 the truncation glyphs, fill that space with a stretch glyph of a
2529 suitably computed width.
2531 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2532 produce_glyphs, to support GUI sessions.
2534 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2536 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2538 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2540 Do not require float-time's arg to fit in time_t (Bug#11825).
2541 This works better on hosts where time_t is unsigned, and where
2542 float-time is applied to the (negative) difference between two times.
2543 * editfns.c (decode_time_components): Last arg is now double *,
2544 not int *, and means to store all the result as a double, without
2545 worrying about whether the seconds part fits in time_t.
2546 All callers changed.
2547 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2548 All callers changed.
2549 (Ffloat_time): Do not fail merely because the specified time falls
2550 outside of time_t range.
2552 2012-07-07 Glenn Morris <rgm@gnu.org>
2554 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2558 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
2560 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2561 Update dependencies.

2569 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2570 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2571 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

2574 * xfont.c (compare_font_names): Redo to omit the need for casts.
2576 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2578 * xfns.c (Fx_change_window_property): Doc fix.
2579 * w32fns.c (Fx_change_window_property): Doc fix.
2581 * w32fns.c (Fx_window_property): Accept the same arguments as the
2582 X Windows version. Doc fix.
2583 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2585 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2586 Eli Zaretskii <eliz@gnu.org>
2588 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2589 Windows-specific code from nt/config.nt moved here.
2590 Obsolete settings removed.
2592 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2594 * process.c: Avoid unnecessary calls to gettime.
2595 (wait_reading_process_output): Don't get the time of day
2596 when gobbling data immediately and not waiting, as there's no need
2597 for it in that case. This removes a FIXME.
2599 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2601 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2602 is defined (Bug#11768).
2604 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2606 Fix marker debugging code.
2607 * marker.c (byte_char_debug_check): Do not perform the check
2608 if buffer is not multibyte.
2609 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2610 Call byte_char_debug_check with correct arguments.
2612 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2614 Compile marker debugging code only if ENABLE_CHECKING is defined.
2615 * marker.c (byte_char_debug_check, count_markers):
2616 Use only if ENABLE_CHECKING is defined.
2617 (byte_debug_flag): Remove.
2618 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2619 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2621 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2623 Avoid code repetition in marker-related functions.
2624 * marker.c (attach_marker): New function.
2625 (Fset_marker, set_marker_restricted, set_marker_both)
2626 (set_marker_restricted_both): Use it.
2627 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2628 Consistently rename charno to charpos.
2629 (marker_position): Add eassert.
2630 (marker_byte_position): Convert to eassert.

2649 * window.c (save_window_save): Likewise.
2651 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2653 Do not use Fdelete_overlay in delete_all_overlays
2654 to avoid redundant calls to unchain_overlay.
2655 * buffer.c (drop_overlay): New function.
2656 (delete_all_overlays, Fdelete_overlay): Use it.
2657 * minibuf.c (get_minibuffer): Fix comment.
2659 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2661 Port to OpenBSD 5.1 amd64.
2662 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2663 This is needed for OpenBSD, and should be harmless on all BSD systems.
2664 Also, include <sys/sysctl.h>, as it should be available on all
2665 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2666 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2667 use p_pid member, not kp_proc.pid.
2669 2012-07-06 Glenn Morris <rgm@gnu.org>
2671 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2673 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2675 More xmalloc and related cleanup.
2676 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2677 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2679 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
2680 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
2681 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
2682 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2683 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2684 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2686 Omit needless casts involving void * pointers and allocation.
2687 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2688 as the former is more robust if P's type is changed.
2689 Prefer xzalloc to xmalloc + memset 0.
2690 Simplify malloc-or-realloc to realloc.
2691 Don't worry about xmalloc returning a null pointer.
2692 Prefer xstrdup to xmalloc + strcpy.
2693 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2695 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2696 alloca of a constant.
2698 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2700 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2701 hscroll is larger than the line width. Fixes long and futile
2702 looping inside extend_face_to_end_of_line (on a TTY) producing
2703 glyphs that are not needed and thrown away.
2705 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2707 * marker.c (set_marker_restricted_both): Simplify by using
2710 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

2720 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2721 followed by gtk_box_set_homogeneous (Bug#11768).
2722 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2723 (update_theme_scrollbar_width, xg_create_scroll_bar):
2724 Use gtk_scrollbar_new (Bug#11768).
2725 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

2733 * xdisp.c (window_hscroll_limited): New function.
2734 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2735 coordinates when window's hscroll is set to insanely large
2738 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2740 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2741 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2743 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2746 * lisp.h (xzalloc): New prototype. Omit needless casts.

2801 * fileio.c (time_error_value): Check the right error number.
2802 Problem reported by Troels Nielsen in
2803 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2805 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2807 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2808 This should be fixed in a better way; see Eli Zaretskii in
2809 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2810 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2812 * fileio.c (time_error_value): Rename from special_mtime.
2813 The old name's problems were noted by Eli Zaretskii in
2814 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2816 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2817 This variable's comment says Emacs needs at least one GDB-visible
2818 symbol of type enum pvec_type, to work around GDB problems.
2819 The symbol's value doesn't matter.
2821 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2822 that causes compilation to fail on pre-C99 compilers.
2824 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2826 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2827 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2829 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2831 * buffer.c (init_buffer_once): Fix initialization of
2832 headers for buffer_defaults and buffer_local_symbols.
2833 Reported by Juanma Barranquero <lekktu@gmail.com>.
2835 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2837 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2838 * lisp.h (enum pvec_type): Use fewer bits.
2839 (PSEUDOVECTOR_SIZE_BITS): New constant.
2840 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2841 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2842 change in pvec_type.
2843 (PSEUDOVECTOR_TYPEP): New macro.
2844 (TYPED_PSEUDOVECTORP): Use it.
2845 * fns.c (internal_equal): Adapt code to extract pvectype.

2847 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2848 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2849 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2850 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2851 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2852 abusing vector->header.next.nbytes.
2853 (live_vector_p): Use PVEC_TYPE.
2854 (mark_object): Adapt code to extract pvectype. Use switch.
2856 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2858 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2859 Tighten new eassert a bit.
2861 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2863 Fix compilation with --enable-gcc-warnings and -O1
2865 * doprnt.c (doprnt): Change type of tem to int, initialize
2866 to avoid compiler warning. Add eassert.
2867 * search.c (simple_search): Initialize match_byte to avoid
2868 compiler warning. Add eassert.
2870 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2872 Avoid weird behavior with large horizontal scrolls.
2873 Without this change, for example, large hscroll values would
2874 mess up Emacs's display on Fedora 15 x86, presumably due to
2875 overflows in int calculations in the display code.
2876 Also, if buffers had long lines, Emacs would freeze.
2877 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2878 (set_window_hscroll): New function, containing the old guts of
2879 Fset_window_hscroll. Return the clipped value.
2880 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2881 This avoids the need to check against PTRDIFF_MAX.
2883 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2885 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2887 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2889 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2891 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2892 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2893 since GCC 4.4.6 issues a bogus warning for them.
2895 Fix bugs in file timestamp newness comparisons.
2896 * fileio.c (Ffile_newer_than_file_p):
2897 * lread.c (Fload): Use full timestamp resolution of files,
2898 not just the 1-second resolution, so that files that are only
2899 slightly newer still count as newer.
2900 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2901 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2903 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2905 * fileio.c: Improve handling of file time marker. (Bug#11852)
2906 (special_mtime): New function.
2907 (Finsert_file_contents, Fverify_visited_file_modtime):
2908 Use it to set special mtime values consistently.
2910 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2912 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2913 marker for non-existing file. (Bug#11852)
2915 2012-07-03 Glenn Morris <rgm@gnu.org>
2917 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2918 and did not make it into globals.h).
2920 2012-07-03 Tom Tromey <tromey@redhat.com>
2922 * window.c (Fset_window_margins, Fset_window_fringes)
2923 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2924 * textprop.c (Fprevious_property_change): No longer static.
2925 * syntax.c (Fsyntax_table_p): No longer static.
2926 * process.c (Fget_process, Fprocess_datagram_address): No longer

2947 * intervals.h: Remove EXFUNs.
2948 * fontset.h: Remove EXFUN.

2953 * w32term.h: Remove EXFUNs.
2954 * window.h: Remove EXFUNs.
2955 * xsettings.h: Remove EXFUN.
2956 * xterm.h: Remove EXFUN.
2958 2012-07-03 Glenn Morris <rgm@gnu.org>
2960 * lisp.h (Frandom): Make it visible to C.
2961 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2962 buffer for invisible buffers. (Bug#1229)
2964 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2966 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2967 values which aren't power of 2.
2968 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
2969 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2972 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2974 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2976 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2978 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2980 * alloc.c (allocate_vector_block): Remove redundant
2981 calls to mallopt if DOUG_LEA_MALLOC is defined.
2982 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2983 avoid calls to mallopt if zero_vector is returned.
2985 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2987 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2988 is enabled, avoid dereferencing NULL current_sblock if
2991 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2993 Cleanup basic buffer management.
2994 * buffer.h (struct buffer): Change layout to use generic vector
2995 marking code. Fix some comments. Change type of 'clip_changed'
2996 to bitfield. Remove unused #ifndef old.
2997 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2998 (GET_OVERLAYS_AT): Fix indentation.
2999 (for_each_per_buffer_object_at): New macro.

3003 * alloc.c (allocate_buffer): Adjust to match new layout of
3004 struct buffer. Fix comment.
3005 (mark_overlay): New function.

3008 (mark_object): Use it. Adjust marking of misc objects
3009 and related comments.
3011 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
3013 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
3014 wrapper that is not needed because the wrapped code is a no-op (zero
3015 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
3016 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
3018 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
3020 * alloc.c (mark_buffer): Simplify. Remove prototype.
3021 (mark_object): Add comment. Reorganize marking of vector-like
3022 objects. Use CHECK_LIVE for all vector-like objects except buffers
3023 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
3024 Avoid redundant calls to mark_vectorlike for bool vectors.
3026 2012-06-30 Glenn Morris <rgm@gnu.org>
3028 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
3030 * epaths.in (PATH_SITELOADSEARCH): New.
3031 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
3032 This is rather than relying on --enable-locallisppath elements
3033 having "site-lisp" in their names. (Bug#10208#25, 11658)
3035 2012-06-30 Eli Zaretskii <eliz@gnu.org>
3037 * w32proc.c (sys_select): Accept and ignore one more argument.
3039 * w32.c (emacs_gnutls_pull): Call select with one more argument.
3041 * sysselect.h [DOS_NT]: Don't include sys/select.h.
3042 (pselect) [!MS_DOS]: Redirect to sys_select.
3044 * sysdep.c: Don't include dos.h and dosfns.h.
3046 * process.c (sys_select):
3047 * msdos.c (sys_select): Accept one more argument and ignore it.
3049 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
3050 adapt data types and code to that.
3053 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
3054 which clashes with the gnulib function of the same name.
3056 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3058 * font.c (font_style_to_value, font_style_symbolic)
3059 (font_prop_validate_style): Add type checks for values in
3062 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3064 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3067 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3069 * xdisp.c (try_window_id): Undo last change.
3071 * w32.c (getwd): Adjust commentary about startup_dir.
3072 (init_environment): Always call sys_access, even in non-MSVC
3073 builds. Don't chdir to the directory of the Emacs executable.
3074 This undoes code from 1997 which was justified by the need to
3075 "avoid conflicts when removing and renaming directories". But its
3076 downside was that every relative file name was being interpreted
3077 relative to the directory of the Emacs executable, which can never
3078 be TRT. In particular, it broke sys_access when called with
3079 relative file names.
3080 (sys_access): Map GetLastError to errno.
3082 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3084 * window.h (struct window): Change type of 'fringes_outside_margins'

3088 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3091 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
3093 * gnutls.c (emacs_gnutls_handshake):
3094 Add QUIT to make the loop interruptible.
3096 2012-06-29 Glenn Morris <rgm@gnu.org>
3098 * charset.c (init_charset): Make lack of etc/charsets fatal.
3100 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3102 * editfns.c (region_limit): Fix type mismatch.
3104 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3106 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3107 undefined. Convert from xassert to eassert.
3108 * nsmenu.m: Convert from xassert to eassert.
3109 * nsterm.m: Likewise.
3111 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3113 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3115 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3117 Avoid integer overflow on scroll-left and scroll-right.
3118 * window.c (HSCROLL_MAX): New macro.
3119 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3120 overflow when requested scroll falls outside ptrdiff_t range.
3122 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3124 * window.h (struct window): Change type of 'hscroll',
3125 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3126 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3127 Adjust users accordingly.
3128 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3129 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3130 from EMACS_INT to ptrdiff_t.
3131 (make_window): Omit redundant initialization.
3133 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
3135 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
3137 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3139 * window.h (struct window): Change type of 'use_time' and
3140 'sequence_number' from Lisp_Object to int.
3141 * frame.c (make_frame): Adjust users accordingly.

3149 enabled with --enable-checking=[all,glyphs] configure option.
3150 Fix GLYPH_DEBUG usage assuming that it may be undefined,
3151 adjust comments accordingly.

3202 avoid GCC warning about unused macro.
3204 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3206 * alloc.c (allocate_string): Omit intervals initialization.
3207 * alloc.c (make_uninit_multibyte_string): Initialize intervals
3208 as in make_pure_string and make_pure_c_string.
3210 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3212 * alloc.c (allocate_string): Fix last change.
3214 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

3233 when building with Clang.
3235 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>
3237 * eval.c (Fapply): Allow calling it with a single argument.
3239 2012-06-26 Eli Zaretskii <eliz@gnu.org>

3264 * alloc.c: Remove build_string.
3265 * lisp.h: Define build_string as static inline. This provides
3266 a better opportunity to optimize away calls to strlen when the
3267 function is called with compile-time constant argument.
3268 * image.c (imagemagick_error): Convert to build_string.
3269 * w32proc.c (sys_spawnve): Likewise.
3270 * xterm.c (x_term_init): Likewise.
3272 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3274 Use sprintf return value instead of invoking strlen on result.
3275 In the old days this wasn't portable, since some sprintf
3276 implementations returned char *. But they died out years ago and
3277 Emacs already assumes sprintf returns int.
3278 Similarly for float_to_string.
3279 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
3280 * ccl.c (ccl_driver):
3281 * character.c (string_escape_byte8):

3284 * print.c (print_object):
3285 * xdisp.c (message_dolog):
3286 * xfns.c (syms_of_xfns):
3287 Use sprintf or float_to_string result to avoid need to call strlen.
3288 * data.c (Fnumber_to_string):
3289 Use make_unibyte_string, since the string must be ASCII.
3290 * lisp.h, print.c (float_to_string): Now returns int length.
3291 * term.c (produce_glyphless_glyph):
3292 Use sprintf result rather than recomputing it.
3294 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3295 * Makefile.in (ALL_CFLAGS):
3296 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
3297 * gmalloc.c, regex.c: Include <config.h> unconditionally.
3299 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3301 * dispextern.h (xstrcasecmp): Define to library function
3302 strcasecmp if available.
3303 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
3305 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

3318 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
3320 * gtkutil.c (get_utf8_string): Remove redundant assignment.
3321 sprintf already null-terminates its output.
3323 * xfns.c (x_window): Remove redundant cast.
3325 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3327 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
3328 `const char *' to `char *' to avoid compiler warning.
3330 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3332 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
3333 instead of truncating it to 63 (admittedly a generous limit).
3335 * process.c: Fix spelling and caps in comments.
3337 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
3339 * emacs.c (setpgrp): Remove definition, unused.

3385 * sound.c (sound_warning, parse_sound):
3386 Remove unnecessary forward decls.
3388 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3390 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
3391 * lisp.h (WAIT_READING_MAX): New macro.
3392 * dispnew.c (Fsleep_for, sit_for):
3393 * keyboard.c (kbd_buffer_get_event):
3394 * process.c (Faccept_process_output):
3395 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3396 This improves on the previous patch, which introduced a bug
3397 when time_t is unsigned and as wide as intmax_t.
3398 See <http://bugs.gnu.org/9000#51>.
3400 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3402 * dispnew.c (sit_for, Fsleep_for):
3403 * keyboard.c (kbd_buffer_get_event):

3416 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
3417 Privately reported by Herbert J. Skuhra.
3418 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
3420 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
3421 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3423 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3425 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
3426 last argument of make_unibyte_string.
3428 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
3429 language ID in the event parameters.
3431 * w32term.c (w32_read_socket): Put the new keyboard codepage into
3432 event.code, not the obscure "character set ID".
3434 2012-06-23 Chong Yidong <cyd@gnu.org>
3436 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
3438 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3455 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
3456 Privately reported by Herbert J. Skuhra.
3457 [__FreeBSD__]: Remove "*/" typo after "#include".

3463 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3465 Support higher-resolution time stamps (Bug#9000).
3466 The time stamps are only nanosecond-resolution at the C level,
3467 since that's the best that any real-world system supports now.
3468 But they are picosecond-resolution at the Lisp level, as that's
3469 easy, and leaves room for future OS improvements.
3471 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3474 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3475 Don't get current time unless it's needed.
3477 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3478 now provides it if it's absent.
3479 (start_atimer): Port to higher-res time stamps.
3480 Check for time stamp overflow. Don't get current time more
3481 often than is needed.
3483 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3484 Include systime.h, not time.h.
3485 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3487 * dired.c: Include stat-time.h.
3488 (Ffile-attributes): File times now have higher resolution.
3490 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3491 (struct image): Timestamp now has higher resolution.
3493 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3494 has at least microseconds now. All uses removed.
3495 (update_frame, update_single_window, update_window, update_frame_1)
3496 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3497 (duration_to_sec_usec): Remove; no longer needed.
3499 * editfns.c (time_overflow): Now extern.
3500 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3501 (float-time, Fformat_time_string, Fcurrent_time_string)
3502 (Fcurrent_time_zone): Accept and generate higher-resolution
3504 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3505 (decode_time_components, lisp_seconds_argument): New functions.
3506 (make_time): Now static.
3507 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3508 Report an error if the time is invalid, rather than having the caller
3511 * fileio.c: Include <stat-time.h>
3512 (Fcopy_file): Copy higher-resolution time stamps.
3513 Prefer to set the time stamp via a file descriptor if that works.
3514 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3515 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3516 (Fvisited_file_modtime, Fset_visited_file_modtime):
3517 Support higher-resolution time stamps.
3519 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3521 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3523 * image.c (prepare_image_for_display, clear_image_cache)
3524 (lookup_image): Port to higer-resolution time stamps.
3526 * keyboard.c (start_polling, bind_polling_period):
3527 Check for time stamp overflow.
3528 (read_char, kbd_buffer_get_event, timer_start_idle)
3529 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3530 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3531 Port to higher-resolution time stamps. Do not assume time_t is signed.
3532 (decode_timer): New function. Timers are now vectors of length 9,
3533 not 8, to accommodate the picosecond component.
3534 (timer_check_2): Use it.
3536 * nsterm.m (select_timeout, timeval_subtract): Remove.
3537 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3538 as they're a bit more accurate and handle overflow better.
3539 (ns_select): Change prototype to be compatible with pselect.
3540 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3541 * nsterm.h (ns_select): Adjust prototype.
3543 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3544 us-resolution time stamps.
3545 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3547 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3549 * lisp.h (time_overflow): New decl.
3550 (wait_reading_process_output): First arg is now intmax_t, not int,
3551 to accommodate larger waits.
3553 * process.h (struct Lisp_Process.read_output_delay):
3554 Now counts nanoseconds, not microseconds.
3555 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3557 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3558 (wait_reading_process_output):
3559 Port to ns-resolution time stamps.
3560 (Faccept_process_output, wait_reading_process_output):
3561 Check for time stamp overflow. Do not assume time_t is signed.
3562 (select_wrapper): Remove; we now use pselect.
3563 (Fprocess_attributes): Now generates ns-resolution time stamps.
3565 * sysdep.c: Include utimens.h. Don't include utime.h
3566 or worry about struct utimbuf; gnulib does that for us now.
3567 (gettimeofday): Remove; gnulib provides a substitute.
3568 (make_timeval): New function.
3569 (set_file_times): Now sets ns-resolution time stamps.
3570 New arg FD; all uses changed.
3571 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3572 (system_process_attributes):
3573 Now returns ns-resolution time stamp. All uses changed.
3574 Check for time stamp overflow.
3576 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3577 provides a substitute now.
3579 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3580 since it guarantees struct timespec.
3581 (EMACS_TIME): Now struct timespec, so that we can support
3582 ns-resolution time stamps.
3583 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3584 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3585 (EMACS_USECS): Remove.
3586 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3587 so multiply the arg by 1000 before storing it.
3588 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3590 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3591 Port to ns-resolution time stamps.
3592 (EMACS_TIME_NEG_P): Remove; replaced by....
3593 (EMACS_TIME_SIGN): New macro.
3594 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3595 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3596 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3597 (make_timeval, make_lisp_time, decode_time_components): New decls.
3598 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3599 that it mishandled time_t overflow. You can't compare by subtracting!
3600 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3601 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3603 * term.c: Include <sys/time.h>.
3604 (timeval_to_Time): New function, for proper overflow wraparound.
3605 (term_mouse_position, term_mouse_click): Use it.
3607 * undo.c (record_first_change): Support higher-resolution time stamps
3609 (Fprimitive_undo): Use them when restoring time stamps.
3611 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3612 (w32_get_internal_run_time):
3613 Port to higher-resolution Emacs time stamps.
3614 (ltime): Now accepts single 64-bit integer, as that's more convenient
3617 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3619 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3620 for compatibility with pselect. Support ns-resolution time stamps.
3622 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3624 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3625 Check for time stamp overflow, and support ns-resolution time stamps.
3627 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3628 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3629 (timeval_subtract): Remove; no longer needed.
3630 (XTflash, XTring_bell, x_wait_for_event):
3631 Port to ns-resolution time stamps. Don't assume time_t is signed.
3633 2012-06-22 Chong Yidong <cyd@gnu.org>
3635 * xdisp.c (x_consider_frame_title): Revert last change.
3637 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3639 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3640 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3641 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3642 staticidx goes up to 1597 out of 1600 = 0x640.)
3644 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3646 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3647 Otherwise, the umask might be mistakenly 0 while handling input signals.
3649 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3651 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
3653 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>

3656 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
3657 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3658 access to `contents' member of Lisp_Vector objects with AREF and ASET
3661 2012-06-19 Chong Yidong <cyd@gnu.org>
3663 * frame.c (delete_frame): When selecting a frame on a different
3664 text terminal, do not alter the terminal's top-frame.
3666 * xdisp.c (format_mode_line_unwind_data): Record the target
3667 frame's selected window and its terminal's top-frame.
3668 (unwind_format_mode_line): Restore them.
3669 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3671 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3672 since tty frames can be explicitly named.
3673 (prepare_menu_bars): Likewise.
3675 * term.c (Ftty_top_frame): New function.
3677 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3679 Port byte-code-meter to modern targets.
3680 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3681 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3682 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3683 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

3916 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3917 Use an inline function on all platforms when using the union type,
3918 since this is simpler and 'static inline' can be used portably

4062 * doprnt.c (doprnt): Truncate multibyte char correctly.
4063 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4064 would mishandle a string argument "Xc" if X was a multibyte
4065 character of length 2: it would truncate after X's first byte
4066 rather than including all of X.

4149 and 'double' in a couple of places.
4151 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4153 * xdisp.c (handle_stop): Detect whether we have overlay strings
4154 loaded by testing it->current.overlay_string_index to be
4155 non-negative, instead of checking whether n_overlay_strings is
4156 positive. (Bug#11587)

4166 * search.c (search_buffer): Remove calls to
4167 r_alloc_inhibit_buffer_relocation, as it is now called by
4168 maybe_unify_char, which was the cause of relocation of buffer text
4171 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4173 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4174 for the duration of call to load_charset, to avoid problems with
4175 callers of maybe_unify_char that access buffer text through C
4178 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4179 decrement the inhibition flag, instead of just setting or
4182 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4184 Remove obsolete '#define static' cruft.
4185 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
4186 This #undef was "temporary" in 2000; it is no longer needed
4187 now that '#define static' has gone away.
4188 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
4189 (gray_bitmap_bits): Remove; no longer needed.
4190 All uses replaced with definiens.
4191 * xterm.c: Include "bitmaps/gray.xbm".
4193 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4195 Clean up __executable_start, monstartup when --enable-profiling.
4196 The following changes affect the code only when profiling.
4197 * dispnew.c (__executable_start): Rename from safe_bcopy.
4198 Define only on platforms that need it.
4199 * emacs.c: Include <sys/gmon.h> when profiling.
4200 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
4201 (__executable_start): Remove decl, since lisp.h does it now.
4202 (safe_bcopy): Remove decl; no longer has that name.
4203 (main): Coalesce #if into single bit of code, for simplicity.
4204 Cast pointers to uintptr_t, since standard libraries want integers
4206 * lisp.h (__executable_start): New decl.
4208 2012-05-31 Glenn Morris <rgm@gnu.org>
4210 * image.c (Fimagemagick_types): Doc fix.
4212 2012-05-30 Jim Meyering <meyering@redhat.com>
4214 * callproc.c (Fcall_process_region): Include directory component

4227 (Qdefun): Move from eval.c.
4228 * lisp.h (Qdefun): Remove.
4229 * lread.c (read1): Tiny simplification.
4231 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4233 Do not create empty overlays with the evaporate property (Bug#9642).
4234 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4235 Bug#9642, but explicitly check that the buffer the overlay would
4236 be moved to is live and rearrange lines to make sure that errors
4237 will not put the overlay in an inconsistent state.
4238 (Fdelete_overlay): Cosmetics.
4240 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4242 * w32term.c (my_bring_window_to_top): New function.
4243 (x_raise_frame): Use handle returned by DeferWindowPos, which
4244 could be different from the original one.
4245 Call my_bring_window_to_top instead of my_set_foreground_window.
4248 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4249 by calling BringWindowToTop.
4251 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4252 (WM_EMACS_END): Increase by one.
4254 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4256 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4257 This avoids undefined behavior that might cause the eassert
4258 to not catch an out-of-range value.
4260 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4262 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4263 Update dependencies.
4265 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4267 * bidi.c (bidi_mirror_char): Fix last change.
4269 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
4271 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
4272 when referring to sectname field in printf format.
4274 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4276 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4277 Only r_alloc_inhibit_buffer_relocation needed to be added;
4278 the others were already declared.
4280 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4281 before checking whether it's out of range. Put the check inside
4283 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4285 2012-05-27 Ken Brown <kbrown@cornell.edu>
4287 * callproc.c (Fcall_process): Restore a line that was accidentally
4288 commented out in the 2011-02-13 change (bug#11547).
4290 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4292 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4293 defined on ralloc.c.
4295 * buffer.c [REL_ALLOC]: Remove prototypes of
4296 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4297 they are now on lisp.h.
4299 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4301 * search.c (search_buffer): Use it to inhibit relocation of buffer
4302 text while re_search_2 is doing its job, because re_search_2 is
4303 passed C pointers to buffer text. (Bug#11519)
4305 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4308 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4309 state after an additional call to move_it_in_display_line_to, keep
4310 the values of it->max_ascent and it->max_descent found for the
4312 (pos_visible_p): Revert the comparison against bottom_y to what it
4313 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4316 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4318 Fix coding-related core dumps with gcc -ftrapv.
4319 The code was computing A - B, where A and B are pointers, and B is
4320 random garbage. This can lead to core dumps on platforms that
4321 have special pointer registers, and it also leads to core dumps on
4322 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4323 A - B only when B is initialized properly.
4324 * coding.c (coding_set_source, coding_set_destination): Return void.
4325 (coding_change_source, coding_change_destinations): New functions,
4326 with the old behaviors of coding_set_source and coding_set_destination.
4327 All callers that need an offset changed to use these new functions.
4329 2012-05-26 Glenn Morris <rgm@gnu.org>
4331 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4333 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4335 Extend mouse support on W32 text-mode console.
4336 * xdisp.c (draw_row_with_mouse_face):
4337 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4339 * w32console.c: Include window.h.
4340 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4342 (initialize_w32_display): Initialize mouse-highlight data.
4344 * w32inevt.c: Include termchar.h and window.h.
4345 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4346 moves, call note_mouse_highlight. If help_echo changed, call
4347 gen_help_event to produce help-echo message in the echo area.
4348 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4351 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4353 * lread.c (read1): Simplify slightly to avoid an overflow warning
4354 with GCC 4.7.0 on x86-64.
4356 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4358 * bidi.c (bidi_mirror_char): Revert last change: an int is
4359 definitely wide enough here.
4361 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4363 Fix integer width and related bugs (Bug#9874).
4364 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
4365 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)

4371 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4373 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4374 (allocate_pseudovector):
4375 Use int, not EMACS_INT, where int is wide enough.
4376 (inhibit_garbage_collection, Fgarbage_collect):
4377 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4378 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4379 int might not be wide enough.
4380 (bidi_cache_search, bidi_cache_find, bidi_init_it)
4381 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

4383 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4384 (bidi_level_of_next_char, bidi_move_to_visually_next):
4385 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4386 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4387 (Fkill_buffer, Fset_buffer_major_mode)
4388 (advance_to_char_boundary, Fbuffer_swap_text)

4391 (overlay_strings, recenter_overlay_lists)
4392 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4393 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4394 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4395 (Foverlay_recenter, last_overlay_modification_hooks_used)
4396 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4397 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4398 (validate_region): Omit unnecessary test for b <= e,
4399 since that's guaranteed by the previous test.
4400 (adjust_overlays_for_delete): Avoid pos + length overflow.
4401 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4402 (report_overlay_modification):
4403 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4404 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4405 Omit pointer cast, which isn't needed anyway, and doesn't work
4406 after the EMACS_INT -> ptrdiff_t change.
4407 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4408 * buffer.h: Adjust decls to match defn changes elsewhere.
4409 (struct buffer_text, struct buffer):

4411 Use EMACS_INT, not int, where int might not be wide enough.
4412 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
4413 not int, to avoid needless 32-bit limit on 64-bit hosts.
4414 (exec_byte_code): Use tighter memory-full test, one that checks
4415 for alloca overflow. Don't compute the address of the object just
4416 before an array, as that's not portable. Use EMACS_INT, not
4417 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4418 * callint.c (Fcall_interactively):
4419 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4420 * callproc.c (call_process_kill, Fcall_process):
4421 Don't assume pid_t fits into an Emacs fixnum.

4430 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4431 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4432 (casify_object): Avoid integer overflow when overallocating buffer.
4433 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4434 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4435 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4436 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4437 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4438 integers are now checked earlier. All uses replaced with XINT.
4440 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4441 For CCL_MapSingle, check that content and value are in int range.
4442 (ccl_driver, Fregister_code_conversion_map):
4443 Check that Vcode_version_map_vector is a vector.
4444 (resolve_symbol_ccl_program): Check that vector header is in range.
4445 Always copy the vector, so that we can check its contents reliably
4446 now rather than having to recheck each instruction as it's being
4447 executed. Check that vector words fit in 'int'.
4448 (ccl_get_compiled_code, Fregister_ccl_program)
4449 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4450 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4451 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4452 contents are in range.
4453 (Fccl_execute_on_string): Check that status is in range.
4454 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4455 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4456 Accept and return EMACS_INT, not int, because callers can pass values
4458 (c_string_width, strwidth, lisp_string_width, chars_in_text)

4461 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4462 (string_escape_byte8, Fget_byte):
4463 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4464 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4465 avoid mishandling large integers.
4466 * character.h: Adjust decls to match defn changes elsewhere.
4467 * charset.c (load_charset_map_from_file, find_charsets_in_text)

4475 (Fdefine_charset_internal): Check ranges here, more carefully.
4476 Don't rely on undefined behavior with signed left shift overflow.
4477 Don't assume unsigned int fits into fixnum, or that fixnum fits
4478 into unsigned int. Don't require max_code to be a valid fixnum;
4479 that's not true for gb10830 4-byte on a 32-bit host. Allow
4480 invalid_code to be a cons, for the same reason. Require code_offset
4481 to be a character. Avoid int overflow if max_char is close
4483 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4484 this is intended anyway and avoids some undefined behavior.
4485 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4486 INDEX_TO_CODE_POINT, as that's what it expects.
4487 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4488 * charset.h (DECODE_CHAR): Return int, not unsigned;
4489 this is what was intended anyway, and it avoids undefined behavior.
4490 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4491 integer-overflow issues.
4492 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4493 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4494 where the argument is EMACS_INT, and this behavior is not intended.
4495 * chartab.c (Fmake_char_table, Fset_char_table_range)
4496 (uniprop_get_decoder, uniprop_get_encoder):
4497 Don't assume fixnum fits in int.
4498 * cmds.c (move_point): New function, that does the gist of
4499 Fforward_char and Fbackward_char, but does so while checking
4500 for integer overflow more accurately.
4501 (Fforward_char, Fbackward_char): Use it.
4502 (Fforward_line, Fend_of_line, internal_self_insert)
4503 (internal_self_insert):
4504 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4505 Fix a FIXME, by checking for integer overflow when calculating
4506 target_clm and actual_clm.

4538 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4539 (consume_chars): Rewrite to not calculate an address outside buffer.
4540 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
4541 Don't access memory outside of the args array.
4542 (Fdefine_coding_system_internal): Check for charset-id overflow.
4543 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4544 result of ENCODE_CHAR.
4545 * coding.h: Adjust decls to match defn changes elsewhere.
4546 (struct coding_system):
4547 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4562 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4563 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
4564 Do not attempt to compute the address of the object just before a
4565 buffer; this is not portable.
4567 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4568 (Faset): Use int, not EMACS_INT, where int is wide enough.
4569 (Fstring_to_number): Don't assume fixnums fit in int.

5300 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5302 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
5303 already have overlays loaded.
5304 (handle_single_display_spec): Before returning without displaying
5305 fringe bitmap, synchronize the bidi iterator with the main display
5306 iterator, by calling iterate_out_of_display_property.
5307 (iterate_out_of_display_property): Detect buffer iteration by
5308 testing that it->string is a Lisp string.
5309 (get_next_display_element): When the current object is exhausted,
5310 and there's something on it->stack, call set_iterator_to_next to
5311 proceed with what's on the stack, instead of returning zero.
5312 (set_iterator_to_next): If called at the end of a Lisp string,
5313 proceed to consider_string_end without incrementing string
5314 position. Don't increment display vector index past the end of
5315 the display vector. (Bug#11417)
5316 (pos_visible_p): Don't report a position visible when move_it_to
5317 stopped at the last line of window, which happens to be scanned
5318 backwards by the bidi iteration. (Bug#11464)
5320 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5322 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5323 and right-margin display specs even if the spec is invalid or we
5324 are on a TTY, and thus unable to display on the fringes.
5325 That's because the text with the property will not be displayed anyway,
5326 so we need to signal to the caller that this is a "replacing"
5327 display spec. This fixes display when the spec is invalid or we
5330 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5332 * unexaix.c (make_hdr): Fix typo in prototype.
5333 This bug broke the build on AIX. Problem reported by Gilles Pion.
5335 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5337 * keyboard.c (kbd_buffer_get_event): Read special events also in
5338 batch mode. (Bug#11415)
5340 2012-05-12 Glenn Morris <rgm@gnu.org>
5342 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5344 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5346 * lisp.mk (lisp): Add newcomment.elc.
5348 2012-05-12 Glenn Morris <rgm@gnu.org>
5350 * Makefile.in (MKDIR_P): New, set by configure.
5351 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5353 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5355 Remove unused function hourglass_started.
5356 * dispextern.h (hourglass_started):
5357 * w32fns.c (hourglass_started):
5358 * xdisp.c (hourglass_started): Remove.
5360 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5362 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5363 Update dependencies.
5365 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5367 * xgselect.c (xg_select): Put maxfds+1 into a var.
5368 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5370 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5372 2012-05-10 Dave Abrahams <dave@boostpro.com>
5374 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5375 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5377 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5379 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5380 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5381 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5382 Initialize xd_registered_buses.
5384 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5386 Untag more efficiently if USE_LSB_TAG.
5387 This is based on a proposal by YAMAMOTO Mitsuharu in
5388 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5389 For an admittedly artificial (nth 8000 longlist) benchmark on
5390 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5391 Emacs's overall text size by 1%.
5392 * lisp.h (XUNTAG): New macro.
5393 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5394 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5395 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5396 * eval.c (Fautoload):
5397 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5398 * frame.h (XFRAME): Use XUNTAG.
5400 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5401 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5402 Remove unportable assumptions about print widths of types like
5404 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5405 intptr_t when converting between pointer and integer, to avoid GCC
5406 warnings about wrong width.
5408 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5410 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5411 stack for each reader_thread, instead of defaulting to 8MB
5412 determined by the linker. This avoids failures in creating
5413 subprocesses on Windows 7, see the discussion in this thread:
5414 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5416 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5418 Fix up display of the *Minibuf-0* buffer in the mini window.
5419 * keyboard.c (read_char): Don't clear the echo area if there's no
5421 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5422 contents of *Minibuf-0*) if there's no message displayed in its stead.
5424 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5426 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5429 2012-05-06 Chong Yidong <cyd@gnu.org>
5431 * lisp.mk (lisp): Update.
5433 2012-05-05 Jim Meyering <meyering@redhat.com>
5435 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5437 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5439 * data.c (PUT_ERROR): New macro.
5440 (syms_of_data): Use it. Add new error type `user-error'.
5441 * undo.c (user_error): New function.
5442 (Fprimitive_undo): Use it.
5443 * print.c (print_error_message): Adjust print style for `user-error'.
5444 * keyboard.c (user_error): New function.
5445 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5447 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5449 Do not limit current-time-string to years 1000..9999.
5450 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5451 (Fcurrent_time_string): Support any year that is supported by the
5452 underlying localtime representation. Don't use asctime, as it
5453 has undefined behavior for years outside the range -999..9999.
5455 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5457 Fix race conditions involving setenv, gmtime, localtime, asctime.
5458 Without this fix, interrupts could mess up code that uses these
5459 nonreentrant functions, since setting TZ invalidates existing
5460 tm_zone or tzname values, and since most of these functions return
5461 pointers to static storage.
5462 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5463 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5464 Grow the critical sections to include not just invoking
5465 localtime/gmtime, but also accessing these functions' results
5466 including their tm_zone values if any, and any related TZ setting.
5467 (format_time_string): Last arg is now struct tm *, not struct tm **,
5468 so that the struct tm is saved in the critical section.
5469 All callers changed. Simplify allocation of initial buffer, partly
5470 motivated by the fact that memory allocation needs to be outside
5471 the critical section.
5473 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5475 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5476 with RESET_INTERVAL.
5478 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5479 Remove duplicated buffer name initialization.
5481 2012-05-02 Jim Meyering <jim@meyering.net>
5483 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5485 * xfns.c (x_window): Use xstrdup (Bug#11375).
5487 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5489 * xdisp.c (pos_visible_p): If already at a newline from the
5490 display string before the 'while' loop, don't walk back the glyphs
5491 from it3.glyph_row. Solves assertion violation when the display
5492 string begins with a newline (egg.el). (Bug#11367)
5494 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5496 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5499 2012-05-01 Glenn Morris <rgm@gnu.org>
5501 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5502 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5503 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5504 All were removed before 23.1.
5506 * dispnew.c: Remove HAVE_LIBNCURSES test;
5507 it is always true on relevant platforms.
5509 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5510 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5512 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5514 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5516 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5517 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5520 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5522 Do not avoid creating empty evaporating overlays (Bug#9642).
5523 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5524 That is, do not delete an evaporating overlay if it becomes
5525 empty after its bounds are adjusted to fit within its buffer.
5526 This fix caused other problems, and I'm reverting it until we get
5527 to the bottom of them.
5529 2012-04-27 Chong Yidong <cyd@gnu.org>
5531 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5533 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5535 * xdisp.c (pos_visible_p): If the window start position is beyond
5536 ZV, start the display from buffer beginning. Prevents assertion
5537 violation in init_iterator when the minibuffer window is scrolled
5540 * window.c (window_scroll_pixel_based): Likewise.
5542 2012-04-27 Chong Yidong <cyd@gnu.org>
5544 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5546 2012-04-27 Glenn Morris <rgm@gnu.org>
5548 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5549 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5551 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5553 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5554 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5556 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5558 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5559 display element, check also the underlying string or buffer
5560 character. (Bug#11341)
5562 * w32menu.c: Include w32heap.h.
5563 (add_menu_item): If the call to AppendMenuW (via
5564 unicode_append_menu) fails, disable Unicode menus only if we are
5565 running on Windows 9X/Me.
5567 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5569 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5570 (xgetint): Add missing shift for LSB tags.
5572 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5574 * keyboard.c (read_char): Don't wipe echo area for select window
5575 events: These might get delayed via `mouse-autoselect-window'
5578 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5580 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5581 manipulation of :loaded-from data.
5583 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5585 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5586 now a cons (bug#11311).
5588 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5590 Do not create empty overlays with the evaporate property (Bug#9642).
5591 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5592 if it becomes empty after its bounds are adjusted to fit within
5593 its buffer. Without this fix, in a nonempty buffer (let ((o
5594 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5595 yields an empty overlay that has the evaporate property, which is
5596 not supposed to happen.
5598 Fix minor GTK3 problems found by static checking.
5599 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

5609 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5610 (EMACS_FIXED_GET_CLASS): Remove; unused.
5611 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5613 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5614 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5616 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5618 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5619 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5620 (__malloc_size_t, __malloc_ptrdiff_t):
5621 Remove. All uses removed, replaced by the definiens if needed,
5622 since we can assume C89 or better now.
5623 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5624 (protect_malloc_state, align, get_contiguous_space)
5625 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5631 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5632 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5633 Define using prototypes, not old style.
5634 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5635 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5636 (align): Don't assume that signed integer overflow wraps around.
5637 Omit unused local var.
5638 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5639 (_free_internal_nolock, memalign, mallochook, reallochook):
5640 Omit no-longer-needed casts.
5641 (valloc): Use getpagesize, not __getpagesize.
5642 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
5643 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5645 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5647 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
5649 Move functions from C to Lisp. Make non-blocking method calls
5650 the default. Implement further D-Bus standard interfaces.

5692 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5694 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
5695 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
5696 Do not assume ptrdiff_t is the same width as 'int'.
5698 * alloc.c: Handle unusual debugging option combinations.
5699 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5700 since the two debugging options are incompatible.
5701 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5703 (mem_init, mem_insert, mem_insert_fixup):
5704 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
5705 (NEED_MEM_INSERT): Remove; no longer needed.
5707 2012-04-22 Leo Liu <sdl.web@gmail.com>

5711 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5713 * sysdep.c [__FreeBSD__]: Minor cleanups.
5714 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5715 Use Emacs indenting style more consistently. Avoid some casts.
5716 Use 'double' consistently rather than mixing 'float' and 'double'.
5718 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5720 * sysdep.c (list_system_processes, system_process_attributes):
5721 Add implementation for FreeBSD (Bug#5243).
5723 2012-04-21 Andreas Schwab <schwab@linux-m68k.org>
5725 * lisp.mk (lisp): Update.
5727 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
5729 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.

5734 * print.c (print_preprocess): Only check print_depth if print-circle
5736 (print_object): Check for cycles even when print-circle is nil and

5739 2012-04-20 Chong Yidong <cyd@gnu.org>
5741 * process.c (wait_reading_process_output): If EIO occurs on a pty,

5755 row, return zero immediately.
5756 (try_cursor_movement): If inside continuation line, don't back up
5757 farther than the first row after the header line, if any.
5758 Don't consider the header-line row as "partially visible", even if
5759 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
5761 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5775 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
5776 -Wunused-result, -Wunused-variable. This should go away once
5777 the Emacs and Gnulib regex code is merged.
5778 (xmalloc, xrealloc): Now static.
5780 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

5793 2012-04-16 Paul Eggert <eggert@cs.ucla.edu>
5795 Fix minor alloc.c problems found by static checking.
5796 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5797 New extern decls, to avoid calling undeclared functions.
5798 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5799 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5800 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5801 (NEED_MEM_INSERT): New macro.
5802 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5803 Remove one incorrect comment and fix another.

5808 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
5809 (r_alloc_sbrk): Now static.
5811 Improve ralloc.c interface checking.
5812 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

5816 [REL_ALLOC]: ... to here, to check interface.
5817 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5818 Remove decls. This fixes an "It stinks!".
5820 * alloc.c (which_symbols): Fix alignment issue / type clash.
5822 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5824 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
5825 (struct Lisp_Misc_Any): Likewise.
5826 (struct Lisp_Free): Likewise.

5835 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5837 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5838 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5839 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5840 * s/netbsd.h, s/sol2-6.h:
5841 Remove definition of GC_MARK_STACK, since the default now works.
5842 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5843 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5844 no longer the default.
5845 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5847 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5849 * lread.c (lisp_file_lexically_bound_p):
5850 Fix hang at ";-*-\n" (bug#11238).

5857 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5859 * nsterm.m (constrainFrameRect): Always constrain when there is only
5860 one screen (Bug#10962).
5862 2012-04-13 Ken Brown <kbrown@cornell.edu>
5864 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

5870 2012-04-11 Daniel Colascione <dancol@dancol.org>
5872 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5873 against is gone. It's better to use vfork now so that when Cygwin
5874 gains a new, working vfork, we use it automatically (bug#10398).
5876 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5878 * window.c (save_window_save): Obey window-point-insertion-type.

5890 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
5891 (force_quit_count): New var.
5892 (handle_interrupt): Use it.
5894 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5896 * w32.c (w32_delayed_load): Record the full path of the library
5897 being loaded (bug#10424).
5899 2012-04-09 Glenn Morris <rgm@gnu.org>
5901 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5902 not just in the obarray, before snarfing them. (Bug#11036)
5904 * Makefile.in ($(leimdir)/leim-list.el):
5905 Pass EMACS rather than BUILT_EMACS.
5907 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5909 * process.c (make_process):
5910 * process.h: Add integer `gnutls_handshakes_tried' member to
5913 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5914 Add convenience `GNUTLS_LOG2i' macro.
5916 * gnutls.c (gnutls_log_function2i): Convenience log function.
5917 (emacs_gnutls_read): Use new log functions,
5918 `gnutls_handshakes_tried' process member, and
5919 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5920 attempts per process (connection).
5922 2012-04-09 Chong Yidong <cyd@gnu.org>

5929 * minibuf.c (Fread_variable): Callers changed.
5931 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5933 * xdisp.c (set_cursor_from_row): If the display string appears in
5934 the buffer at position that is closer to point than the position
5935 after the display string, display the cursor on the first glyph of
5936 the display string. Fixes cursor display when a 'display' text
5937 property immediately follows invisible text. (Bug#11094)
5939 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5941 composite.c: use 'double' consistently
5942 * composite.c (get_composition_id): Use 'double' consistently
5943 instead of converting 'float' to 'double' and vice versa; this is
5944 easier to understand and avoids a GCC warning.
5946 2012-04-09 Glenn Morris <rgm@gnu.org>
5948 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5949 preparation for dumping it with emacs. (Bug#4789)

5968 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5970 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5971 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5972 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5973 objects, as mark_maybe_pointer will catch them otherwise.
5974 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5975 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5977 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5979 Fix typo that broke non-Windows builds.
5980 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5982 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5984 Support building on MS-Windows with libxml2.
5986 * makefile.w32-in (OBJ2): Add xml.$(O).
5987 (GLOBAL_SOURCES): Add xml.c.
5988 ($(BLD)/xml.$(O)): New dependency list.
5990 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5991 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5992 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5993 [!WINDOWSNT]: New macros.
5994 (init_libxml2_functions, libxml2_loaded_p): New functions.
5995 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5996 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5997 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5998 Calls xmlCleanupParser only if libxml2 was loaded (or statically
6000 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
6001 Call init_libxml2_functions before calling libxml2 functions.
6002 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
6004 * emacs.c: Don't include libxml/parser.h.
6005 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
6006 xmlCleanupParser directly.
6008 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
6010 2012-04-07 Eli Zaretskii <eliz@gnu.org>
6012 * indent.c (Fvertical_motion): If there is a display string at
6013 point, use it.vpos to compute how many lines to backtrack after
6014 move_it_to point. (Bug#11133)
6016 2012-04-06 Eli Zaretskii <eliz@gnu.org>
6018 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
6019 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
6020 about subtle differences between FETCH_CHAR* and STRING_CHAR*
6021 macros related to unification of CJK characters. For the details,
6022 see the discussion following the message here:
6023 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
6025 2012-04-04 Chong Yidong <cyd@gnu.org>
6027 * keyboard.c (Vdelayed_warnings_list): Doc fix.
6029 2012-04-01 Eli Zaretskii <eliz@gnu.org>
6031 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
6032 instead of alloca. (Bug#11138)

6039 2012-03-31 Eli Zaretskii <eliz@gnu.org>
6041 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
6042 position we get to after a call to move_it_to fails the
6043 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
6044 only if we wind up in a string from display property. (Bug#11063)
6046 * window.c (Fdelete_other_windows_internal): Invalidate the row
6047 and column information about mouse highlight, so that redisplay
6048 restores it after reallocating the glyph matrices. (Bug#7464)
6050 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
6051 string comes from a `display' text property, use the buffer
6052 position of that property as if we actually saw that position in
6054 (move_it_by_lines): Remove the assertion that
6055 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6056 violated when there's a before-string at the beginning of a line.
6059 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6061 * xdisp.c (append_space_for_newline): If the default face was
6062 remapped, use the remapped face for the appended newline.
6063 (extend_face_to_end_of_line): Use the remapped default face for
6064 extending the face to the end of the line.
6065 (display_line): Call extend_face_to_end_of_line when the default
6066 face was remapped. (Bug#11068)
6068 2012-03-29 Eli Zaretskii <eliz@gnu.org>
6070 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

6088 * keyboard.c (Vselection_inhibit_update_commands): New variable.
6089 (command_loop_1): Use it; inhibit selection update for
6090 handle-select-window too (Bug#8996).
6092 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
6094 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
6096 2012-03-25 Kenichi Handa <handa@m17n.org>
6098 * dispextern.h (struct glyph): Change the bit length of
6099 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6101 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6103 * s/ms-w32.h (tzname): Include time.h before redirecting to
6104 _tzname. Fixes the MSVC build. (Bug#9960)
6106 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
6108 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6111 * xterm.c (XTread_socket): Only modify handling_signal if
6112 !SYNC_INPUT. (Bug#11080)
6114 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6116 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6117 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6118 when fetching a multibyte character consumes more bytes than
6119 CHAR_BYTES returns, due to unification of CJK characters in
6120 string_char. (Bug#11073)
6122 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6124 * process.c (wait_reading_process_output): Handle pty disconnect
6125 by refraining from sending oneself a SIGCHLD (bug#10933).

6136 2012-03-21 Chong Yidong <cyd@gnu.org>
6138 * xfaces.c (Vface_remapping_alist): Doc fix.
6140 2012-03-20 Eli Zaretskii <eliz@gnu.org>
6142 * w32proc.c (Fw32_set_console_codepage)
6143 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

6148 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
6149 to reflect default non-nil value of redisplay-dont-pause.
6151 2012-03-19 Kenichi Handa <handa@m17n.org>

6154 it fit in a valid range (Bug#11003).
6156 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6158 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6159 that is not from display property, accept the row as a "cursor
6160 row" if one of the string's character has a non-nil `cursor'
6161 property. Fixes cursor positioning when there are newlines in
6162 overlay strings, e.g. in icomplete.el. (Bug#11035)
6164 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6166 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
6168 2012-03-12 Chong Yidong <cyd@gnu.org>
6170 * eval.c (inhibit_lisp_code): Rename from
6171 inhibit_window_configuration_change_hook; move from window.c.
6173 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6174 * window.c (run_window_configuration_change_hook)
6175 (syms_of_window): Callers changed.
6177 2012-03-11 Chong Yidong <cyd@gnu.org>
6179 * keymap.c (Fkey_description): Doc fix (Bug#9700).
6181 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
6183 2012-03-10 Chong Yidong <cyd@gnu.org>
6185 * frame.c (other_visible_frames): Don't assume the selected frame
6186 is visible (Bug#10955).
6188 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
6190 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6192 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6194 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6195 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6198 2012-03-03 Glenn Morris <rgm@gnu.org>
6200 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6202 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6204 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6205 position past the first glyph_row that ends at ZV. (Bug#10902)
6206 (redisplay_window, next_element_from_string): Fix typos in
6208 (redisplay_window): Pass to move_it_vertically the margin in
6209 pixels, not in screen lines.
6211 2012-03-02 Glenn Morris <rgm@gnu.org>
6213 * buffer.c (buffer-list-update-hook): Doc fix.
6215 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6217 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6218 push_it before setting up the iterator for the first overlay
6219 string, even if we have an empty string loaded.
6220 (next_overlay_string): If there's an empty string on the iterator
6221 stack, pop the stack. (Bug#10903)
6223 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6225 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6226 Suggested by Stefan Monnier in
6227 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6228 * alloc.c (widen_to_Lisp_Object): New static function.
6229 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6230 and widening them to Lisp_Objects. This would work even if
6231 USE_LSB_TAG is defined and wide integers are used, which might
6232 happen in a future version of Emacs.
6234 2012-02-25 Chong Yidong <cyd@gnu.org>

6273 when computing $valmask.
6275 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6276 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6277 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6278 It's useless in that case, and it can cause problems on hosts
6279 that allocate halves of EMACS_INT values separately.
6280 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6281 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6282 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6283 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6284 it avoids undefined behavior on hosts where shifting right by more
6285 than the word width has undefined behavior.
6287 2012-02-19 Chong Yidong <cyd@gnu.org>
6289 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

6333 highlight (Bug#9904).
6335 2012-02-12 Glenn Morris <rgm@gnu.org>

6367 * buffer.c (Fbuffer_local_variables)
6368 (buffer_lisp_local_variables): Handle unbound vars correctly;

6371 2012-02-07 Glenn Morris <rgm@gnu.org>
6373 * image.c (Fimagemagick_types): Doc fix.
6375 * image.c (imagemagick-render-type): Change it from a lisp object

6411 * character.c (char_width): Return EMACS_INT, not int.
6412 (char_width, c_string_width): Check for overflow when
6413 computing the width; this is possible now that individual
6414 characters can have unbounded width. Problem introduced
6415 by merge from Emacs 23 on 2012-01-19.

7087 behave as if the cursor position were at the window margin.
7089 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7090 and the cursor position is out of bounds, behave as if the cursor

7121 * dispnew.c (verify_row_hash): Call row_hash for computing the
7122 hash code of a row, instead of duplicating code from xdisp.c.
7124 * dispextern.h (row_hash): Add prototype.
7126 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

7229 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
7231 Avoid some portability problems by eschewing 'extern inline' functions.
7232 The trivial performance wins aren't worth the portability hassles; see
7233 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
7235 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
7236 (window_box_width, window_box_left, window_box_left_offset)
7237 (window_box_right, window_box_right_offset): Undo previous change,
7238 by removing the "extern"s.
7239 * intervals.c (adjust_intervals_for_insertion)
7240 (adjust_intervals_for_deletion): Undo previous change,
7241 making these static again.
7242 (offset_intervals, temp_set_point_both, temp_set_point)
7243 (copy_intervals_to_string): No longer inline.
7244 * xdisp.c (window_text_bottom_y, window_box_width)
7245 (window_box_height, window_box_left_offset)
7246 (window_box_right_offset, window_box_left, window_box_right)

7259 * lisp.h (syms_of_abbrev): Remove declaration.
7260 Reported by CHENG Gao <chenggao@royau.me>.
7262 2011-11-07 Eli Zaretskii <eliz@gnu.org>
7264 * w32.c (check_windows_init_file): Don't look for term/w32-win.el
7265 if Vpurify_flag is non-nil. Fixes a crash when running w32 build
7266 of temacs in GUI mode.
7268 2011-11-07 Martin Rudalics <rudalics@gmx.at>
7270 * window.h: Declare delete_all_child_windows instead of
7271 delete_all_subwindows.
7272 * window.c (Fwindow_nest, Fset_window_nest)
7273 (Fset_window_new_total, Fset_window_new_normal)

7275 (delete_all_subwindows): Rename to delete_all_child_windows.
7276 (Fdelete_other_windows_internal, Fset_window_configuration):
7277 Call delete_all_child_windows instead of delete_all_subwindows.
7278 * frame.c (delete_frame): Call delete_all_child_windows instead
7279 of delete_all_subwindows.
7281 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
7283 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
7284 This is also needed for porting to any host where GC_MARK_STACK is
7285 not GC_MAKE_GCPROS_NOOPS.
7286 (which_symbols): Use it.
7288 2011-11-07 Kenichi Handa <handa@m17n.org>
7290 * coding.c (coding_set_destination): Check coding->src_pos only

7297 process_coding to 0 (bug#9912).
7299 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7301 * xmenu.c (cleanup_widget_value_tree): New function.
7302 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
7303 calling free_menubar_widget_value_tree directly (Bug#9830).
7305 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
7307 Fix some portability problems with 'inline'.
7308 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
7309 (window_box_width, window_box_left, window_box_left_offset)
7310 (window_box_right, window_box_right_offset): Declare extern.
7311 Otherwise, these inline functions do not conform to C99 and
7312 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7313 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7314 * intervals.c (adjust_intervals_for_insertion)
7315 (adjust_intervals_for_deletion): Now extern, because otherwise the
7316 extern inline functions 'offset_intervals' couldn't refer to it.
7317 (static_offset_intervals): Remove.
7318 (offset_intervals): Rewrite using the old contents of
7319 static_offset_intervals. The old version didn't conform to C99
7320 because an extern inline function contained a reference to an
7321 identifier with static linkage.
7323 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
7325 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

7341 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
7342 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
7343 (Fwindow_vscroll): Doc fix.
7344 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
7345 argument, since it makes no sense to pass a live window and for
7346 consistency with window-child.

7373 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
7374 (unwind_create_frame): New function (Bug#9943).
7375 (Fx_create_frame): Restructure code to be more similar to the one in
7376 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
7377 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
7378 Move terminal->reference_count++ just before making the frame official
7381 * nsterm.m (x_free_frame_resources): New function.
7382 (x_destroy_window): Move code to x_free_frame_resources.
7384 * xfns.c (unwind_create_frame): Fix comment.

7386 Move terminal->reference_count++ just before making the frame
7387 official. Move initialization of image_cache_refcount and
7388 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

7427 * xdisp.c (note_mouse_highlight): If either of
7428 previous/next-single-property-change returns nil, treat that as
7429 the beginning or the end of the buffer. (Bug#9955)

7433 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
7434 label is not null (Bug#9951).

7456 (mouse_face_from_buffer_pos, note_mouse_highlight):
7457 Rename cover_string to disp_string.
7459 2011-11-01 Martin Rudalics <rudalics@gmx.at>

7490 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
7492 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
7493 so that this new function doesn't get optimized away by a
7494 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
7496 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
7498 * frame.h (MOUSE_HL_INFO): Remove excess parens.
7500 2011-10-29 Eli Zaretskii <eliz@gnu.org>

7519 Not clear what it was for, and it causes various bugs. (Bug#9839)
7521 2011-10-28 Eli Zaretskii <eliz@gnu.org>
7523 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
7524 possible random value that matches one of those tested as
7525 condition to clear the mouse face.
7527 2011-10-28 Chong Yidong <cyd@gnu.org>
7529 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

7554 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
7556 (w32font_open_internal, compute_metrics):
7557 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7558 instead of calling the "wide" APIs directly.
7560 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
7562 * w32.h (syms_of_w32font): Add prototype.
7564 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
7566 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
7567 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
7568 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

7571 2011-10-27 Chong Yidong <cyd@gnu.org>
7573 * process.c (make_process): Set gnutls_state to NULL.
7575 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
7576 non-NULL, regardless of GNUTLS_INITSTAGE.
7577 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7578 an error. Set process slots as soon as we allocate them.

7624 current character, check also for next_en_type being WEAK_EN.
7625 (bidi_resolve_weak): Don't enter the expensive loop if the current
7626 position is before next_en_pos. Record the bidi type of the first
7627 non-ET, non-BN character we find, in addition to its position.
7628 (bidi_level_of_next_char): Invalidate next_en_type when
7629 next_en_pos is over-stepped.
7631 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7633 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7634 * editfns.c: Rewrite current-time-zone so that it invokes
7635 the equivalent of (format-time-string "%Z") to get the time zone name.
7636 This fixes a bug when the time zone name contains characters that
7637 need converting from the system time locale to Emacs internal format.
7638 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7639 that patch fixed format-time-string to do the conversion, but
7640 I forgot to fix current-time-zone.
7641 (format_time_string): New function, containing most of
7642 what Fformat_time_string used to contain.
7643 (Fformat_time_string): Rewrite in terms of format_time_string.
7644 This doesn't change this function's behavior.
7645 (current-time-zone): Rewrite to use format_time_string.
7646 This fixes the bug reported by Michael Schierl in
7647 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7648 Jason Rumney's 2007-06-07 change worked around this bug, but
7650 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7652 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7654 * xdisp.c (start_display): If the character at POS is displayed
7655 via a display vector, reset IT->current.dpvec_index to zero.
7656 (try_window_reusing_current_matrix): If a line ends in a display
7657 vector or the next line starts in a display vector, continue
7658 redrawing the window even though the character position of
7659 start_row was reached.
7662 2011-10-18 Chong Yidong <cyd@gnu.org>
7664 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7665 with nobreak-char-display too.
7667 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7669 Fix part 3 of bug#9771.
7670 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7671 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7672 non-neutral characters if the current character is a paragraph
7673 separator (a.k.a. Newline). This avoids running the same
7674 expensive loop twice, once when we consume the preceding newline
7675 and the other time when the line actually needs to be displayed.
7676 Avoid the loop when we see neutrals on the base embedding level
7677 following a character whose directionality is the same as the
7678 paragraph's. This avoids running the expensive loop when a line
7679 ends in a long sequence of neutrals, like control characters.
7680 Add assertion against STRONG_AL type. Slightly rearrange code
7681 that determines the type of a neutral given the first non-neutral
7683 (bidi_level_of_next_char): Set next_en_pos to zero when
7684 invalidating its info.
7686 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7688 * xdisp.c (push_display_prop): Determine whether to record string
7689 or buffer position by IT->string, not by IT->method. Allow
7690 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7691 (move_it_vertically_backward): Don't look for character position
7692 immediately after the newline when in a continuation line.
7695 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7697 * window.c (coordinates_in_window): Rewrite and delabelize
7698 vertical border check. (Bug#5357) (Bug#9618)
7700 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7702 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7703 errors in XSetWindowBorder (bug#9310).
7705 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7707 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7708 avoid crash when xmalloc overrun checking is enabled.
7710 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7712 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7713 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7714 cursor motion with <left> and <right> arrow keys.
7716 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7717 some callers set that themselves.
7719 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7721 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7722 display string and the previous row comes from the same string and
7723 is empty. (Bug#9739) (Bug#9738)
7725 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7727 * doc.c (get_doc_string): Encode file name (bug#9735).
7729 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7731 * bidi.c (bidi_level_of_next_char):
7732 * xdisp.c (get_visually_first_element): Remove old incorrect
7733 comments regarding the Unicode Line Separator character.
7735 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7737 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7739 * alloc.c (Fgc_status): Do not access beyond zombies array
7740 boundary if nzombies > MAX_ZOMBIES.
7741 * alloc.c (dump_zombies): Add missing format specifier.
7743 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7745 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7746 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7748 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7749 Some packages use them to denote characters with modifiers.
7751 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7753 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7754 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7755 matching a pp-number. Rename parameter var to var1.
7757 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7759 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7761 2011-10-08 Glenn Morris <rgm@gnu.org>
7763 * callint.c (Fcall_interactively): Give a more explicit error for the
7764 'c' case with a non-character input. (Bug#8479)
7766 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7768 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7770 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7771 lines that are hscrolled on the left.
7773 * dispnew.c (buffer_posn_from_coords): Account for a possible
7774 presence of header-line. (Bug#4426)
7776 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7778 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7779 Don't advertise functionality which we discourage or doesn't work.
7781 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7783 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7784 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7785 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7786 this makes Emacs dump core during garbage collection on rare
7787 occasions. sizeof is obviously inferior to offsetof here, so
7788 stick with offsetof.
7789 (GC_POINTER_ALIGNMENT): New macro.
7790 (mark_memory): Omit 3rd (offset) arg; caller changed.
7791 Don't assume EMACS_INT alignment is the same as pointer alignment.
7793 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7795 * keyboard.c (read_key_sequence_remapped): New var.
7796 (read_key_sequence): Compute remapping in the right buffer.
7797 (command_loop_1): Use read_key_sequence's remapping directly.
7799 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7801 * dired.c (file_name_completion): Don't expand file name.
7802 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7803 before checking file name handler.
7805 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7806 they've been requested explicitly (bug#9591).
7808 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7810 * keymap.c (Fsingle_key_description): Use make_specified_string
7811 instead of build_string to build string from push_key_description.
7814 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7816 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7817 This fixes a Y2038 bug on 64-bit hosts.
7818 * buffer.c (reset_buffer):
7819 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7820 (Fclear_buffer_auto_save_failure):
7821 Use 0, not -1, to represent an unset failure time, since time_t
7822 might not be signed.
7824 Remove dependency on glibc malloc internals.
7825 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7826 Move back here from lisp.h, but with their new implementations.
7827 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7828 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7829 * charset.c (charset_table_init): New static var.
7830 (syms_of_charset): Use it instead of xmalloc. This removes a
7831 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7832 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7833 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7834 Move back to alloc.c.
7835 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7836 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7838 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7840 * nsterm.m (windowDidResize): Call x_set_window_size only when
7841 ns_in_resize is true. Otherwise set pixelwidth/height and
7842 call change_frame_size (Bug#9628).
7844 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7846 Port --enable-checking=all to Fedora 14 x86-64.
7847 * charset.c (syms_of_charset): Also account for glibc malloc's
7848 internal overhead when calculating the initial malloc maximum.
7850 Port --enable-checking=all to Fedora 14 x86.
7851 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7853 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7854 (overrun_check_realloc, overrun_check_free):
7855 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7856 That way, xmalloc returns a properly-aligned pointer even if
7857 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7858 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7859 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7860 into account when calculating the initial malloc maximum.
7861 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7862 Move here from alloc.c, so that charset.c can use it too.
7863 Properly align; the old code wasn't right for common 32-bit hosts
7864 when configured with --enable-checking=all.
7865 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7866 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7868 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7870 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7873 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7875 * xdisp.c (compute_display_string_end): If there's no display
7876 string at CHARPOS, return -1.
7878 * bidi.c (bidi_fetch_char): When compute_display_string_end
7879 returns a negative value, treat the character as a normal
7880 character not covered by a display string. (Bug#9624)
7882 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7884 * lread.c (Fread_from_string): Fix typo in docstring.
7886 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7888 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7889 newline, reseat the iterator instead of bidi-iterating there one
7890 character at a time. (Bug#9610)
7891 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7892 TO_CHARPOS if the bidi iterator is at base embedding level.
7894 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7896 * lread.c (readevalloop): Use correct code for NBSP.
7897 (read1): Likewise. (Bug#9608)
7899 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7901 * dbusbind.c (Fdbus_register_signal): When service is not
7902 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7904 2011-09-25 Glenn Morris <rgm@gnu.org>
7906 * buffer.c (truncate-lines): Doc fix.
7908 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7910 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7911 (Fset_window_next_buffers): Doc fix.
7913 2011-09-24 Glenn Morris <rgm@gnu.org>
7915 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7917 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7919 Fix minor problems found by static checking.
7920 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7921 * indent.c (Fvertical_motion): Fix == vs = typo.
7923 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7925 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7926 Default value is now t. Doc fix.
7928 * indent.c (Fvertical_motion): Compute and apply the overshoot
7929 logic when moving up, not only when moving down. Fix the
7930 confusing name and values of the it_overshoot_expected variable;
7931 logic changes accordingly. (Bug#9254) (Bug#9549)
7933 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7934 CHARPOS is covered by a display string which includes newlines.
7935 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7936 is covered by a display string with embedded newlines.
7938 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7940 * dbusbind.c (Fdbus_register_signal): Add match rule to
7941 Vdbus_registered_objects_table. (Bug#9581)
7942 (Fdbus_register_method, Vdbus_registered_objects_table):
7945 2011-09-24 Jim Meyering <meyering@redhat.com>
7947 do not ignore write error for any output size
7948 The previous change was incomplete.
7949 While it makes emacs --batch detect the vast majority of stdout
7950 write failures, errors were still ignored whenever the output size is
7951 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7952 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7953 && echo FAIL: ignored write error
7954 FAIL: ignored write error
7955 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7956 && echo FAIL: ignored write error
7957 FAIL: ignored write error
7958 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)

7963 non-successfully if a write error occurred on stdout. (Bug#9574)
7965 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7967 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7970 * dispextern.h (struct it): Update the comment documenting what
7973 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7975 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7976 a display string, extend search for cursor position to end of row.
7977 (find_row_edges): If the row ends in a newline from a display
7978 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7979 Handle the case of a display string with multiple newlines.
7980 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7981 non-empty line. Fixes confusing cursor motion with arrow keys at
7982 the beginning of a line that starts with whitespace.

7994 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7996 * xdisp.c (display_line): Record maximum and minimum buffer
7997 positions even if no glyphs were produced (e.g., by a zero-width
7998 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7999 buffer positions that will be removed from the glyph row because
8001 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
8002 column is beyond frame width: don't subtract 1 "pixel" when
8003 computing width of the stretch.
8004 (reseat_at_next_visible_line_start): Undo the change made on
8005 2011-09-17 that saved paragraph information and restored it after
8006 the call to `reseat'. (Bug#9545)
8008 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8010 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
8011 and turn window cursor on if cleared (Bug#9415).

8025 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
8026 initialized, to pacify gcc -Wuninitialized.
8028 * fileio.c: Report proper errno when syscall falls.
8029 (Finsert_file_contents): Save and restore errno,
8030 so that report_file_error outputs the correct diagnostic.
8031 (Fwrite_region) [CLASH_DETECTION]: Likewise.
8033 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8035 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
8037 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8039 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
8040 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
8042 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8044 * xdisp.c (reseat_at_next_visible_line_start): Keep information
8045 about the current paragraph and restore it after the call to reseat.
8047 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
8048 (bidi_find_paragraph_start): Search back for paragraph beginning
8049 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.

8051 computations when the last character is a newline or at EOB, not
8052 just any NEUTRAL_B. (Bug#9470)

8059 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8060 (cons_to_x_long): New function.
8061 (lisp_data_to_selection_data): Use it. Correct the test for
8062 short-versus-long data; it was negated. Break out of vector
8063 loop, for efficiency, when a long datum is discovered.
8065 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8067 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8069 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8071 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see

8095 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8096 This occurs when processing a multibyte format.
8097 Problem reported by Wolfgang Jenker.
8099 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8101 * xdisp.c (try_cursor_movement): Only check for exact match if
8102 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8104 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8106 Remove unused external symbols.
8107 * dispextern.h (calc_pixel_width_or_height): Remove decl.

8112 * xterm.c, xterm.h (x_catching_errors): Remove.
8114 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8116 * xselect.c: Use signed conversions more consistently (Bug#9498).
8117 (selection_data_to_lisp_data): Assume incoming selection data are
8118 signed integers, not unsigned. This is to be consistent with
8119 outgoing selection data, which was modified to use signed integers
8120 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8121 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8122 expects long, not unsigned long.

8155 value for non-existent files.
8157 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8159 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8160 set its "size" to -1. This will set the modtime_size field of
8161 the corresponding buffer to -1, which is what
8162 verify-visited-file-modtime expects for files that do not exist.
8165 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8167 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8169 * lisp.h: ... from here. push_key_description is no longer
8170 defined in keyboard.c, so its declaration should not be in
8171 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8172 logically belongs with push_key_description.
8174 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8176 * buffer.h: Include <sys/types.h> instead of <time.h>.
8177 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8178 Problem reported by Herbert J. Skuhra.
8180 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8182 * xml.c (parse_region): Make the parsing work for
8183 non-comment-starting XML files again (bug#9144).
8185 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8187 * image.c (gif_load): Fix calculation of bottom and right corner.
8190 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8192 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8193 redisplay in small windows.
8195 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8197 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8199 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8201 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8202 Operate on live windows only.
8204 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8206 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8208 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8210 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8211 only under bidi iteration.
8213 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8215 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8217 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8219 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8220 Without this fix, the command to link temacs failed due to an
8221 undefined symbol __builtin_isnan. This is because
8222 /usr/include/iso/math_c99.h #defines isnan(x) to
8223 __builtin_isnan(x), but the bundled gcc, which identifies itself
8224 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8226 * floatfns.c (isnan): #undef, and then #define to a clone of
8228 (Fisnan): Always define, since it's always available now.
8229 (syms_of_floatfns): Always define isnan at the Lisp level.
8231 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8233 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8235 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8237 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8238 The previous code assumed that file offsets (off_t values) fit in
8239 EMACS_INT variables, which is not true on typical 32-bit hosts.
8240 The code messed up by falsely reporting buffer overflow in cases
8241 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8242 when "big" contains more than 2**29 bytes, even though this
8243 inserts just one byte and does not overflow the buffer.
8244 (Finsert_file_contents): Store file offsets as off_t
8245 values, not as EMACS_INT values. Check for overflow when
8246 converting between EMACS_INT and off_t. When checking for
8247 buffer overflow or for overlap, take the offsets into account.
8248 Don't use EMACS_INT for small values where int suffices.
8249 When checking for overlap, fix a typo: ZV was used where
8250 ZV_BYTE was intended.
8251 (Fwrite_region): Don't assume off_t fits into 'long'.
8252 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8254 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8256 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8258 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8260 sprintf-related integer and memory overflow issues (Bug#9412).
8262 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8263 (esprintf, exprintf, evxprintf): New functions.
8264 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8265 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8266 (modify_event_symbol): Do not assume that the length of
8267 name_alist_or_stem is safe to alloca and fits in int.
8268 (Fexecute_extended_command): Likewise for function name and binding.
8269 (Frecursion_depth): Wrap around reliably on integer overflow.
8270 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8271 since some callers pass EMACS_INT values.
8272 (Fsingle_key_description): Don't crash if symbol name contains more
8273 than MAX_ALLOCA bytes.
8274 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8275 (get_minibuffer): Arg is now EMACS_INT, not int.
8276 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8277 (esprintf, exprintf, evxprintf): New decls.
8278 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8280 * dbusbind.c (signature_cat): New function.
8281 (xd_signature, Fdbus_register_signal):
8282 Do not overrun buffer; instead, report string overflow.
8284 * dispnew.c (add_window_display_history): Don't overrun buffer.
8285 Truncate instead; this is OK since it's just a log.
8287 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8288 even if the time zone offset is outlandishly large.
8289 Don't mishandle offset == INT_MIN.
8291 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8292 when creating daemon; the previous buffer-overflow check was incorrect.
8294 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8295 which has the guts of the old verror function.
8297 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8298 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8300 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8301 (font_unparse_xlfd): Don't blindly alloca long strings.
8302 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8303 fits in int, when using sprintf. Use single snprintf to count
8304 length of string rather than counting it via multiple sprintfs;
8305 that's simpler and more reliable.
8306 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8307 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8308 sprintf, in case result does not fit in int.
8310 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8311 (fontset_from_font): Print it.
8313 * frame.c (tty_frame_count): Now printmax_t, not int.
8314 (make_terminal_frame, set_term_frame_name): Print it.
8315 (x_report_frame_params): In X, window IDs are unsigned long,
8316 not signed long, so print them as unsigned.
8317 (validate_x_resource_name): Check for implausibly long names,
8318 and don't assume name length fits in 'int'.
8319 (x_get_resource_string): Don't blindly alloca invocation name;
8320 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8323 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8324 (xg_check_special_colors, xg_set_geometry):
8325 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8327 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8328 Use esprintf, not sprintf, in case result does not fit in int.
8330 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8331 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8332 it as a large positive number.
8333 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8334 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8336 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8337 in case result does not fit in int.
8339 * print.c (float_to_string): Detect width overflow more reliably.
8340 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8341 buffer overrun. Don't assume list length fits in 'int'. Treat
8342 print length of 0 as 0, not as infinity; to be consistent with other
8343 uses of print length in this function. Don't overflow print length
8344 index. Don't assume hash table size fits in 'long', or that
8345 vectorlike size fits in 'unsigned long'.
8347 * process.c (make_process): Use printmax_t, not int, to format
8348 process-name gensyms.
8350 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8352 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8353 to avoid potential buffer overrun.
8355 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8356 if X resource line is longer than 512 bytes.
8358 * xfns.c (x_window): Make sprintf buffer a bit bigger
8359 to avoid potential buffer overrun.
8361 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8363 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8365 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8367 Integer overflow fixes for scrolling, etc.
8368 Without these, Emacs silently mishandles large integers sometimes.
8369 For example, "C-u 4294967297 M-x recenter" was treated as if
8370 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8372 * xdisp.c (try_window_id): Check Emacs fixnum range before
8373 converting to 'int'.
8375 * window.c (window_scroll_line_based, Frecenter):
8376 Check that an Emacs fixnum is in range before assigning it to 'int'.
8377 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8378 values converted from Emacs fixnums.
8379 (Frecenter): Don't wrap around a line count if it is out of 'int'
8380 range; instead, treat it as an extreme value.
8381 (Fset_window_configuration, compare_window_configurations):
8382 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8384 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8385 that can exceed INT_MAX. Check that EMACS_INT value is in range
8386 before assigning it to the (possibly-narrower) index.
8387 (match_limit): Don't assume that a fixnum can fit in 'int'.
8389 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8392 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8393 (Fvertical_motion): Don't wrap around LINES values that don't fit
8394 in 'int'. Instead, treat them as extreme values. This is good
8395 enough for windows, which can't have more than INT_MAX lines anyway.
8397 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8399 * Require libxml/parser.h to avoid compilation warning.
8401 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8403 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8404 since this reportedly can destroy thread storage.
8406 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8408 * syntax.c (find_defun_start): Update all cache variables if
8409 exiting early (Bug#9401).
8411 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8413 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8415 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8416 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8417 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8419 * term.c (tty_append_glyph): New function.
8420 (produce_stretch_glyph): Static function and its prototype deleted.
8422 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8425 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8427 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8428 when checking :margin (Bug#9390).
8429 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8430 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8431 so that the name doesn't mislead. All uses changed.
8433 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8435 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8438 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8440 * xdisp.c (move_it_to): Don't bail out early when reaching
8441 position beyond to_charpos, if we are scanning backwards.
8442 (move_it_vertically_backward): When DY == 0, make sure we get to
8443 the first character in the line after the newline.
8445 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8447 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8448 (ccl_driver): Do not generate an out-of-range pointer.
8449 (Fccl_execute_on_string): Remove unnecessary check for
8450 integer overflow, noted by Stefan Monnier in
8451 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8452 Remove a FIXME that didn't need fixing.
8453 Simplify the newly-introduced buffer reallocation code.
8455 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8457 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8459 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8461 Integer and memory overflow issues (Bug#9196).
8463 * doc.c (get_doc_string): Rework so that
8464 get_doc_string_buffer_size is the actual buffer size, rather than
8465 being 1 less than the actual buffer size; this makes xpalloc more
8468 * image.c (x_allocate_bitmap_record, cache_image):
8469 * xselect.c (Fx_register_dnd_atom):
8470 Simplify previous changes by using xpalloc.
8472 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8473 since either will do and ptrdiff_t is convenient with xpalloc.
8475 * charset.c (charset_table_size)
8476 (struct charset_sort_data.priority): Now ptrdiff_t.
8477 (charset_compare): Don't overflow if priorities differ greatly.
8478 (Fsort_charsets): Don't assume list length fits in int.
8479 Check for size-calculation overflow when allocating sort data.
8480 (syms_of_charset): Allocate an initial charset table that is
8481 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8483 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8485 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8486 The actual value is always <= INT_MAX, and leaving it unsigned made
8487 overflow checking harder.
8489 * dispextern.h (struct glyph_matrix.rows_allocated)
8490 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8491 with xpalloc. The values are still always <= INT_MAX.
8493 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8495 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8496 (SAFE_NALLOCA): New macro.
8498 * region-cache.c (struct boundary.pos, find_cache_boundary)
8499 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8500 (set_cache_region, invalidate_region_cache)
8501 (revalidate_region_cache, know_region_cache, region_cache_forward)
8502 (region_cache_backward, pp_cache):
8503 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8504 so that ptrdiff_t * can be passed to xpalloc.
8505 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8506 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8507 (pp_cache): Don't assume cache_len fits in int.
8508 * region-cache.h: Adjust extern decls to match.
8510 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8511 EMACS_INT, since either will do, for xpalloc.
8513 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8514 (xnmalloc, xnrealloc, xpalloc): New functions.
8516 * bidi.c (bidi_shelve_header_size): New constant.
8517 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8518 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8520 * bidi.c (bidi_cache_shrink):
8521 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8523 Don't update size of array until after memory allocation succeeds,
8524 because xmalloc/xrealloc may not return.
8525 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8526 now that we have proper integer overflow checking.
8527 (record_overlay_string, overlay_strings): Catch overflows when
8528 calculating size of overlay_str_buf.
8530 * callproc.c (Fcall_process): Check for size overflow when
8531 calculating size of args2.
8532 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8533 Normally we prefer signed values, but sticking with ptrdiff_t would
8534 require adding more-complicated checks.
8536 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8537 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8538 Redo buffer-overflow calculations to avoid integer overflow.
8539 Add a FIXME comment where memory seems to be over-allocated.
8541 * character.c (Fstring): Check for size-calculation overflow.
8543 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8544 unnecessary integer overflow. Check for size overflow.
8545 (encode_coding_object): Don't update size until xmalloc succeeds.
8547 * composite.c (get_composition_id): Check for overflow in glyph
8548 length calculations.
8550 Integer and memory overflow fixes for display code.
8551 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8552 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8553 (scrolling_window): Check for overflow in size calculations.
8554 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8555 Don't assume glyph table len fits in int.
8556 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8557 (row_table_size): Now ptrdiff_t, not int.
8558 (scrolling_window): Avoid overflow in size calculations.
8559 Don't update size until allocation succeeds.
8560 * fns.c (concat): Check for overflow in size calculations.
8561 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8562 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8563 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8565 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8566 (get_doc_string): Check for size calculation overflow.
8567 Don't update size until allocation succeeds.
8568 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8569 EMACS_INT, where ptrdiff_t will do.
8570 (Fsubstitute_command_keys): Check for string overflow.
8572 * editfns.c (set_time_zone_rule): Don't assume environment length
8574 (message_length): Now ptrdiff_t, not int.
8575 (Fmessage_box): Don't update size until allocation succeeds.
8576 Don't assume message length fits in int.
8577 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8579 * emacs.c (main): Do not reallocate argv, since there is a null at
8580 the end that can be overwritten, and this way there's no need to
8581 worry about size-calculation overflow.
8582 (sort_args): Check for size-calculation overflow.
8584 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8586 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8588 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8589 (x_set_scroll_bar_width, x_figure_window_size):
8590 Check for integer overflow.
8591 (x_set_alpha): Do not assume XINT fits in int.
8593 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8594 This is for the members text_lines, text_cols, total_lines, total_cols,
8595 where the system imposes an 'int' limit.
8597 * fringe.c (Fdefine_fringe_bitmap):
8598 Don't update size until alloc works.
8600 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8601 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8603 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8604 Check for size-calculation overflow.
8605 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8606 do, as we prefer signed integers.
8607 (id_to_widget.max_size, id_to_widget.used)
8608 (xg_store_widget_in_map, xg_remove_widget_from_map)
8609 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8610 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8611 Use and return ptrdiff_t, not int.
8612 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8613 * gtkutil.h: Change prototypes to match the above.
8615 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8616 are duplicate now that they've been promoted to lisp.h.
8617 (x_allocate_bitmap_record, x_alloc_image_color)
8618 (make_image_cache, cache_image, xpm_load):
8619 Don't update size until alloc is done.
8620 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8622 Check for size calculation overflow.
8623 (ct_colors_allocated_max): New constant.
8624 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
8627 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
8628 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
8629 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8630 Use ptrdiff_t, not int, to count maps.
8631 (read_char_minibuf_menu_prompt): Check for overflow in size

8660 (Fset_match_data): Don't assume list lengths fit in 'int'.
8662 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,

8694 Check for size calculation overflow.
8695 (cache_face): Treat size calculation overflows as if they were
8696 memory exhaustion (the usual treatment), rather than aborting.
8698 * xfns.c (x_encode_text, x_set_name_internal)
8699 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8700 sizes, since they can exceed INT_MAX in size. Check for size

8704 (xg_select): Check for size calculation overflow.
8705 Don't update size until alloc done.
8707 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8708 as sprintf is limited to int lengths.
8710 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8711 (X_LONG_MIN): New macros.
8712 Use them to make the following changes clearer.
8713 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8714 This change doesn't affect the value now, but it may help remind
8715 future maintainers not to raise the value too much later.
8716 (SELECTION_QUANTUM): Remove, replacing with ...
8717 (selection_quantum): ... new function, which avoids overflow.
8719 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8720 assumption that selection length fits in 'int'.

8733 (lisp_data_to_selection_data, x_property_data_to_lisp):
8734 Check for size-calculation overflow.

8737 Don't store size until memory allocation succeeds.
8738 (x_get_window_property): Plug memory leak on memory exhaustion.
8739 Don't double-block input; malloc is safe here. Don't assume 2**34
8740 - 4 fits in unsigned long. Add an xassert to check
8741 XGetWindowProperty overflow. Be more careful about overflow
8742 calculations, and distinguish size from memory overflow better.
8743 (receive_incremental_selection): When tracing, don't assume
8744 unsigned int is less than INT_MAX.
8745 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

8748 in the range -65535 through -1 fit in an X unsigned short.
8749 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8750 result parameters unless successful. Rely on cons_to_unsigned
8751 to report problems with elements; the old code wasn't right anyway.
8752 (x_check_property_data): Check for int overflow; we cannot use
8753 a wider type due to X limits.
8754 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8786 * lisp.h (hash_lookup, hash_put):
8787 * minibuf.c (Ftest_completion):
8788 Use ptrdiff_t for hash table indexes, not int (which is too
8789 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8790 32-bit --with-wide-int hosts).
8792 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8793 Add a FIXME comment about memory leaks.

8823 (x_send_scroll_bar_event): Likewise. Check that the size does not
8824 exceed limits imposed by XClientMessageEvent, as well as the usual
8825 ptrdiff_t and size_t limits.
8827 * keyboard.c: Overflow, signedness and related fixes.
8828 (make_lispy_movement): Use same integer type in forward decl
8829 that is used in the definition.
8830 (read_key_sequence, keyremap_step):
8831 Change bufsize argument back to int, undoing my 2011-03-30 change.
8832 We prefer signed types, and int is wide enough here.
8833 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8834 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8835 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8836 length, not size_t. Use ptrdiff_t for index, not int.
8837 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8838 possibility of integer overflow.

8865 (png_load, gif_load, svg_load_image):
8866 Prefer int to unsigned where either will do.
8867 (tiff_handler): New function, combining the cores of the
8868 old tiff_error_handler and tiff_warning_handler.
8869 This function is rewritten to use vsnprintf and thereby avoid
8870 stack buffer overflows. It uses only the features of vsnprintf
8871 that are common to both POSIX and native Microsoft.
8872 (tiff_error_handler, tiff_warning_handler): Use it.
8873 (tiff_load, gif_load, imagemagick_load_image):
8874 Don't assume :index value fits in 'int'.
8875 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

8877 the integer types that MagickCropImage accepts. Don't assume
8878 Vimagemagick_render_type has a nonnegative value. Don't assume
8879 size_t fits in 'long'.
8880 (gs_load): Use printmax_t to print the widest integers possible.

8893 handle_single_display_spec, not just 1 or zero.
8894 (handle_single_display_spec): If the display spec is of the form
8895 `(space ...)', and specifies display in the text area, return 2
8897 (try_cursor_movement): Check for the need to scroll more
8898 accurately, and prefer exact match for point under bidi.
8899 Don't advance `row' beyond the last row of the window.
8901 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8902 into disp_prop; all users changed.
8904 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8920 positioning on the newline at EOL of R2L text within L2R
8921 paragraph, and vice versa.
8922 (try_cursor_movement): Check continued rows, in addition to
8923 continuation rows. Fixes unwarranted scroll when point enters a
8924 continued line of R2L text within an L2R paragraph, or vice versa.
8925 (cursor_row_p): Consider the case of point being equal to
8926 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8927 from the end of a short line to the beginning of a continued line
8928 of R2L text within L2R paragraph.

8955 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8956 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8957 candidate is selected by the mouse, and that candidate has a
8958 composed character under the mouse.
8960 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8961 coordinates reported by pos-visible-in-window-p for a composed

8976 * image.c (gif_load): Don't assume that each subimage has the same
8977 dimensions as the base image. Handle disposal method that is
8978 "undefined" by the gif spec (Bug#9335).
8980 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8982 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8987 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8988 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8989 from an Org mode buffer to a Speedbar frame.
8991 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8992 a composition, take its buffer position from IT->cmp_it.charpos.
8993 Fixes cursor positioning at the beginning of a line that begins
8994 with a composed character.
8996 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8998 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8999 character bidirectional type, use STRONG_L instead. Fixes crashes
9000 in a buffer produced by `describe-categories'.
9002 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
9003 members before the level stack, so they would be saved and
9004 restored when copying iterator state. Fixes incorrect reordering
9005 around TABs covered by display properties.
9007 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

9093 the event loop. Get status from as_status (Bug#7276).
9095 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9096 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
9097 the event loop (Bug#7276).
9099 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
9101 * gnutls.c (QCgnutls_bootprop_priority)
9102 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
9103 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
9104 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
9105 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
9106 (QCgnutls_bootprop_verify_hostname_error)
9107 (QCgnutls_bootprop_callbacks_verify): Rename from
9108 Qgnutls_bootprop_..., all uses changed.
9110 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
9113 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
9115 * xfaces.c (Qframe_set_background_mode): Now static.
9116 * dispextern.h (Qframe_set_background_mode): Remove decl.
9118 * process.c (Fnetwork_interface_info): Declare local only if needed.
9120 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
9122 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
9123 (Fnetwork_interface_list): Allocate in increments of bytes instead
9124 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
9125 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
9127 (struct ifflag_def): notrailers is smart on OSX.
9128 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9129 Get hardware address with getifaddrs if available.
9131 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9133 * xdisp.c (iterate_out_of_display_property): xassert that
9134 IT->position is set to within IT->object's boundaries. Break from
9135 the loop as soon as EOB is reached; avoids infloops in redisplay
9136 when IT->position is set up wrongly due to some bug.
9137 Set IT->current to match the bidi iterator unconditionally.
9138 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9139 entry. Force push_it to save on the stack the current
9140 buffer/string position, to be restored by pop_it. Fix flags in
9141 the iterator structure wrt the object coming from a display
9142 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9143 properties. (Bug#9284)
9145 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9147 * fontset.c (fontset_get_font_group): Add proper type checks.
9150 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9152 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
9153 and LC_VERSION_MIN_MACOSX.
9154 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
9155 (dump_it) [LC_FUNCTION_STARTS]: Use it.
9157 2011-08-08 Eli Zaretskii <eliz@gnu.org>
9159 * xdisp.c (forward_to_next_line_start): Allow to use the
9160 no-display-properties-and-no-overlays under bidi display.
9161 Set disp_pos in the bidi iterator to avoid searches for display
9162 properties and overlays.
9164 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9166 * editfns.c (Fset_time_zone_rule): Document relationship with the
9169 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9170 the font entity extracted from the cache (Bug#8109).
9172 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9174 * composite.c (autocmp_chars): Don't reset point. That is done by
9175 restore_point_unwind (Bug#5984).
9177 2011-08-07 Juri Linkov <juri@jurta.org>
9179 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9180 to show the arg `TIME' instead of `TIMEVAL'.
9182 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9184 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9185 display property strides EOL and includes a newline, as in
9186 longlines-mode. (Bug#9254)
9187 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9188 word-wrap under bidirectional display. (Bug#9224)
9190 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9191 is non-zero, even if the data buffer is NULL. Fixes a crash in
9192 vertical-motion with longlines-mode. (Bug#9254)
9194 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9196 * bidi.c <bidi_cache_total_alloc>: Now static.
9197 (bidi_initialize): Initialize bidi_cache_total_alloc.
9199 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9202 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9203 amount allocated this far in `bidi_cache_total_alloc'.
9204 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9205 non-zero, only free the data buffer without restoring the cache
9206 contents. All callers changed.
9208 * dispextern.h (bidi_unshelve_cache): Update prototype.
9210 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9211 (move_it_in_display_line, move_it_to)
9212 (move_it_vertically_backward, move_it_by_lines): Replace the call
9213 to xfree to an equivalent call to bidi_unshelve_cache.
9214 (move_it_in_display_line_to): Fix logic of returning
9215 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9217 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9219 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9220 came from a string character with a `cursor' property. (Bug#9229)
9222 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9224 * Makefile.in (LIB_PTHREAD): New variable.
9225 (LIBES): Add LIB_PTHREAD (Bug#9216).
9227 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9228 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9230 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9232 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9234 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9236 * xterm.c (x_find_topmost_parent): New function.
9237 (x_set_frame_alpha): Find topmost parent window with
9238 x_find_topmost_parent and set the property there also (bug#9181).
9239 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9241 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9243 * callproc.c (Fcall_process): Avoid vfork clobbering
9244 the local vars buffer, coding_systems, current_dir.
9246 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9248 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9250 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9252 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9253 so that it is not optimized away.
9255 * xdisp.c (compute_display_string_pos): Remove unused local.
9257 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9259 Fix slow cursor motion and scrolling in large buffers with
9260 selective display, like Org Mode buffers. (Bug#9218)
9262 * dispextern.h (struct bidi_it): New member disp_prop_p.
9264 * xdisp.c: Remove one-slot cache of display string positions.
9265 (compute_display_string_pos): Accept an additional argument
9266 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9267 for a display string or property. If found, set DISP_PROP_P
9270 * bidi.c (bidi_fetch_char): Accept an additional argument
9271 DISP_PROP_P, and pass it to compute_display_string_pos.
9272 Only handle text covered by a display string if DISP_PROP_P is returned
9273 non-zero. All callers of bidi_fetch_char changed.
9275 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9277 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9279 2010-12-03 Don March <don@ohspite.net>
9281 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9282 last character M-[char] is translated to ESC [char] (bug#7541).
9284 2011-08-02 Kenichi Handa <handa@m17n.org>
9286 * lisp.h (uniprop_table): Extern it.
9288 * chartab.c (uniprop_table): Make it non-static.
9290 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9292 * xdisp.c (forward_to_next_line_start): Accept additional argument
9293 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9295 (reseat_at_next_visible_line_start): Use the bidi iterator state
9296 returned by forward_to_next_line_start to restore the state of
9297 it->bidi_it after backing up to previous newline. (Bug#9212)
9299 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9301 * regex.c (re_comp): Protoize.
9302 (re_exec): Fix return type.
9303 (regexec): Fix type of `ret'. (Bug#9203)
9305 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9307 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9308 This is needed if max-image-size is a floating-point number.
9310 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9312 * print.c (print_object): Print empty symbol as ##.
9314 * lread.c (read1): Read ## as empty symbol.
9316 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9318 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9319 setting frame foreground color (Bug#9175).
9320 (x_set_background_color): Likewise.
9322 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9323 contents (Bug#9176).
9324 (EmacsTooltip -init): Remove bezels and add shadows to
9327 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9328 or scroll bar (Bug#8470).
9330 * nsfont.m (nsfont_open): Remove assignment to voffset and
9331 unnecessary vars hshink, expand, hd, full_height, min_height.
9332 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9334 * nsterm.h (nsfont_info): Remove voffset field.
9336 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9338 Implement strike-through and overline on NextStep (Bug#8863).
9340 * nsfont.m (nsfont_open): Use underline position provided by font,
9341 instead of hard-coded value of 2.
9342 (nsfont_draw): Call ns_draw_text_decoration instead.
9344 * nsterm.h: Add declaration for ns_draw_text_decoration.
9346 * nsterm.m (ns_draw_text_decoration): New function for drawing
9347 underline, overline, and strike-through.
9348 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9349 ns_draw_text_decoration. Change treatment of cursor drawing to
9350 accommodate underlining, etc.
9352 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9354 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9357 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9359 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9360 Without this fix, if a signal arrives just after memory fills up,
9361 'malloc' might be invoked reentrantly.
9363 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9364 In other words, assume that every image size is allowed, on non-X
9365 hosts. This assumption is probably wrong, but it lets Emacs compile.
9367 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9369 * regex.c (re_iswctype): Convert return values to boolean.
9371 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9373 * xdisp.c (compute_display_string_pos): Don't use cached display
9374 string position if the buffer had its restriction changed.
9377 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9379 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9381 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9383 Integer signedness and overflow and related fixes. (Bug#9079)
9385 * bidi.c: Integer size and overflow fixes.
9386 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9387 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9388 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9389 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9390 (bidi_find_other_level_edge):
9391 Use ptrdiff_t instead of EMACS_INT where either will do.
9392 This works better on 32-bit hosts configured --with-wide-int.
9393 (bidi_cache_ensure_space): Check for size-calculation overflow.
9394 Use % rather than repeated addition, for better worst-case speed.
9395 Don't set bidi_cache_size until after xrealloc returns, because it
9397 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9398 (bidi_cache_ensure_space): Also check that the bidi cache size
9399 does not exceed that of the largest Lisp string or buffer. See Eli
9400 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9402 * alloc.c (__malloc_size_t): Remove.
9403 All uses replaced by size_t. See Andreas Schwab's note
9404 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9406 * image.c: Improve checking for integer overflow.
9407 (check_image_size): Assume that f is nonnull, since
9408 it is always nonnull in practice. This is one less thing to
9409 worry about when checking for integer overflow later.
9410 (x_check_image_size): New function, which checks for integer
9411 overflow issues inside X.
9412 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9413 This removes the need for a memory_full check.
9414 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9415 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9416 (xbm_read_bitmap_data): Change locals back to 'int', since
9417 their values must fit in 'int'.
9418 (xpm_load_image, png_load, tiff_load):
9419 Invoke x_create_x_image_and_pixmap earlier,
9420 to avoid much needless work if the image is too large.
9421 (tiff_load): Treat overly large images as if
9422 x_create_x_image_and_pixmap failed, not as malloc failures.
9423 (gs_load): Use x_check_image_size.
9425 * gtkutil.c: Omit integer casts.
9426 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9427 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9429 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9431 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9432 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9433 would wrongly return t on a 64-bit host.
9435 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9436 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9437 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9438 and therefore cause GCC to emit a bogus diagnostic in some cases.
9440 * image.c: Integer signedness and overflow and related fixes.
9441 This is not an exhaustive set of fixes, but it's time to
9442 record what I've got.
9443 (lookup_pixel_color, check_image_size): Remove redundant decls.
9444 (check_image_size): Don't assume that arbitrary EMACS_INT values
9445 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9446 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9447 (tiff_load, imagemagick_load_image):
9448 Check for overflow in size calculations.
9449 (x_create_x_image_and_pixmap): Remove unnecessary test for
9450 xmalloc returning NULL; that can't happen.
9451 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9452 (xpm_color_bucket): Use better integer hashing function.
9453 (xpm_cache_color): Don't possibly over-allocate memory.
9454 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9455 (gif_memory_source):
9456 Use ptrdiff_t, not int or size_t, to record sizes.
9457 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9458 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9459 either works, as we prefer signed integers.
9460 (tiff_read_from_memory, tiff_write_from_memory):
9461 Return tsize_t, not size_t, since that's what the TIFF API wants.
9462 (tiff_read_from_memory): Don't fail simply because the read would
9463 go past EOF; instead, return a short read.
9464 (tiff_load): Omit no-longer-needed casts.
9465 (Fimagemagick_types): Don't assume size fits into 'int'.
9467 Improve hashing quality when configured --with-wide-int.
9468 * fns.c (hash_string): New function, taken from sxhash_string.
9469 Do not discard information about ASCII character case; this
9470 discarding is no longer needed.
9471 (sxhash-string): Use it. Change sig to match it. Caller changed.
9472 * lisp.h: Declare it.
9473 * lread.c (hash_string): Remove, since we now use fns.c's version.
9474 The fns.c version returns a wider integer if --with-wide-int is
9475 specified, so this should help the quality of the hashing a bit.
9477 * emacs.c: Integer overflow minor fix.
9478 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9479 Define only if GNU_LINUX.
9480 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9482 * dispnew.c: Integer signedness and overflow fixes.
9483 Remove unnecessary forward decls, that were a maintenance hassle.
9484 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9486 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9487 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9488 (prepare_desired_row, line_draw_cost):
9489 Use int, not unsigned, where either works.
9490 (save_current_matrix, restore_current_matrix):
9491 Use ptrdiff_t, not size_t, where either works.
9492 (init_display): Check for overflow more accurately, and without
9493 relying on undefined behavior.
9495 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9496 Remove, replacing with the new symbols in lisp.h. All uses changed.
9497 * fileio.c (make_temp_name):
9498 * filelock.c (lock_file_1, lock_file):
9499 * xdisp.c (message_dolog):
9500 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9501 Use pMd etc. instead.
9502 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9503 replacing the pWIDE etc. symbols removed from editfns.c.
9505 * keyboard.h (num_input_events): Now uintmax_t.
9506 This is (very slightly) less likely to mess up due to wraparound.
9509 * buffer.c: Integer signedness fixes.
9510 (alloc_buffer_text, enlarge_buffer_text):
9511 Use ptrdiff_t rather than size_t when either will do, as we prefer
9514 * alloc.c: Integer signedness and overflow fixes.
9515 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9516 (__malloc_size_t): Default to size_t, not to int.
9517 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9518 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9519 Prefer ptrdiff_t to size_t when either would do, as we prefer
9521 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9522 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9523 Now const. Initialize with values that are in range even if char
9525 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9526 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9527 These functions do the right thing with sizes > 2**32.
9528 (check_depth): Now ptrdiff_t, not int.
9529 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9530 Adjust to new way of storing sizes. Check for size overflow bugs
9532 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9533 slightly wrong anyway, as it missed one instance of
9534 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9535 (refill_memory_reserve): Omit needless cast to size_t.
9536 (mark_object_loop_halt): Mark as externally visible.
9538 * xselect.c: Integer signedness and overflow fixes.
9539 (Fx_register_dnd_atom, x_handle_dnd_message):
9540 Use ptrdiff_t, not size_t, since we prefer signed.
9541 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9542 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9543 x_dnd_atoms_size and x_dnd_atoms_length.
9545 * doprnt.c: Prefer signed to unsigned when either works.
9547 * doprnt.c (doprnt):
9549 * xdisp.c (vmessage):
9550 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9551 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9552 prefer signed arithmetic to avoid comparison confusion.
9553 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9554 but is a bit tricky.
9556 Assume freestanding C89 headers, string.h, stdlib.h.
9557 * data.c, doprnt.c, floatfns.c, print.c:
9558 Include float.h unconditionally.
9559 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9560 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9561 * regex.c: Likewise for stddef.h, string.h.
9562 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9563 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9564 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9565 (STDC_HEADERS): Remove obsolete defines.
9566 * sysdep.c: Include limits.h unconditionally.
9568 Assume support for memcmp, memcpy, memmove, memset.
9569 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9570 * regex.c (memcmp, memcpy):
9571 Remove; we assume C89 now.
9573 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9574 (__malloc_safe_bcopy): Remove; no longer needed.
9576 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9577 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9578 well either way, and we prefer signed to unsigned.
9580 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9582 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9583 closes the connection while we're reading (bug#9182).
9585 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9587 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9588 are specified (Bug#9168).
9590 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9592 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9593 Found by GCC static checking and --with-wide-int on a 32-bit host.
9595 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9597 * xdisp.c (compute_display_string_pos): Fix logic of caching
9598 previous display string position. Initialize cached_prev_pos to
9599 -1. Fixes slow-down at the beginning of a buffer.
9601 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9603 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9604 for attrs[LFACE_FONTSET_INDEX].
9606 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9608 * xml.c (parse_region): Remove unused local
9609 that was recently introduced.
9611 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9613 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9614 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9616 * xdisp.c (move_it_in_display_line_to): Record the best matching
9617 position for TO_CHARPOS while scanning the line, and restore it on
9618 exit if none of the characters scanned was an exact match.
9619 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9620 when exact match is impossible due to invisible text, and the
9621 lines are truncated.
9623 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9625 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9628 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9630 Fix a significant slow-down of cursor motion with C-n, C-p,
9631 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9632 auto-repeat under bidi redisplay in fontified buffers.
9633 * xdisp.c (compute_stop_pos_backwards): New function.
9634 (next_element_from_buffer): Call compute_stop_pos_backwards to
9635 find a suitable prev_stop when we find ourselves before
9637 (reseat): Don't look for prev_stop, as that could mean a very long
9639 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9640 <cached_disp_overlay_modiff>: Cache for last found display string
9642 (compute_display_string_pos): Return the cached position if asked
9643 about the same buffer in the same area of character positions, and
9644 the buffer wasn't changed since the time the display string
9645 position was cached.
9647 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9649 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9650 is an integer, which is important for empty lines. (Bug#9149)
9652 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9654 * frame.c (Fmodify_frame_parameters): In tty case, update the
9655 default face if necessary (Bug#4238).
9657 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9659 * editfns.c (Fstring_to_char): No need to explain what a character
9660 is in the docstring (Bug#6576).
9662 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9664 * xml.c (parse_region): Make sure we always return a tree.
9666 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9668 * xml.c (parse_region): If a document contains only comments,
9671 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9673 * xml.c (make_dom): Return comments, too.
9675 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9678 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9679 and the surrounding thread.
9680 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9681 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9682 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9684 * s/openbsd.h (BROKEN_SIGIO): Define.
9685 * unexelf.c (unexec) [__OpenBSD__]:
9686 Don't update the .mdebug section of the Alpha COFF symbol table.
9688 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9690 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9693 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9695 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9696 This fixes some race conditions on the permissions of any newly
9699 * alloc.c (valid_pointer_p): Use pipe, not open.
9700 This fixes some permissions issues when debugging.
9702 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9703 If fchown fails to set both uid and gid, try to set just gid,
9704 as that is sometimes allowed. Adjust the file's mode to eliminate
9705 setuid or setgid bits that are inappropriate if fchown fails.
9707 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9709 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9710 to compare Lisp_Objects.
9711 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to

9715 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9717 * lread.c (read_integer): Unread even EOF character.
9718 (read1): Likewise. Properly record start position of symbol.
9720 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9721 symbol character follows.
9723 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9725 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9726 This works around a problem with the previous change to Fcopy_file.
9727 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9728 and without this change, GCC might complain about discarding
9729 fchown's return value.
9731 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9733 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9735 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9737 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9739 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9741 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9742 it's used from the C level.
9744 * process.c: Use the same condition for POLL_FOR_INPUT in both
9745 keyboard.c and process.c (bug#1858).
9747 2011-07-09 Lawrence Mitchell <wence@gmx.li>

9754 * doc.c (Fsubstitute_command_keys): Revert last change.
9756 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9758 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9759 quotes the next character, and doesn't affect other longer
9760 sequences (bug#8935).
9762 * lread.c (syms_of_lread): Clarify that is isn't only
9763 `eval-buffer' and `eval-defun' that's affected by
9764 `lexical-binding' (bug#8460).
9766 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9768 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9769 bidi redisplay when a line includes both an image and is truncated.
9771 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9773 Fix minor problems found by static checking.
9774 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9775 (elsz): Now a signed constant, not a size_t var. We prefer signed
9776 types to unsigned, to avoid integer comparison confusion. Without
9777 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9778 "cannot optimize loop, the loop counter may overflow", a symptom
9780 * indent.c (Fvertical_motion): Mark locals as initialized.
9781 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9783 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9785 * search.c (Fre_search_backward): Mention `case-fold-search' in
9786 all the re_search_* functions (bug#8138).
9788 * keyboard.c (Fopen_dribble_file): Document when the file is

9803 NULL (avoids a crash in bidi_paragraph_init).
9804 Initialize itb.string.lstring.
9805 (init_iterator): Call bidi_init_it only of a valid
9806 buffer position was specified. Initialize paragraph_embedding to
9808 (reseat_to_string): Initialize the bidi iterator.
9809 (display_string): If we need to ignore text properties of
9810 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9811 original value of -1 will not work with bidi.)

9813 `text_pos *'; all callers changed. Support display properties on
9815 (compute_display_string_end): Support display properties on Lisp
9817 (init_iterator, reseat_1, reseat_to_string): Initialize the
9818 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9819 when iterating on a string not from display properties).
9820 (compute_display_string_pos, compute_display_string_end):
9821 Fix calculation of the object to scan. Fixes an error when using
9823 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9824 base_level_stop; instead, set base_level_stop to BEGV.
9825 Fixes crashes in vertical-motion.
9826 (next_element_from_buffer): Improve commentary for when
9827 the iterator is before prev_stop.
9828 (init_iterator): Initialize bidi_p from the default value of
9829 bidi-display-reordering, not from buffer-local value. Use the
9830 buffer-local value only if initializing for buffer iteration.
9831 (handle_invisible_prop): Support invisible properties on strings
9832 that are being bidi-reordered.
9833 (set_iterator_to_next): Support bidi reordering of C strings and
9835 (next_element_from_string): Support bidi reordering of Lisp
9837 (handle_stop_backwards): Support Lisp strings as well.

9843 (next_element_from_string, next_element_from_c_string)
9844 (next_element_from_buffer): Add xassert's for correspondence
9845 between IT's object being iterated and it->bidi_it.string

9849 character that is not the first one in the visual order.
9850 (get_visually_first_element): New function, refactored from common
9851 parts of next_element_from_buffer, next_element_from_string, and
9852 next_element_from_c_string.
9853 (tool_bar_lines_needed, redisplay_tool_bar)
9854 (display_menu_bar): Force left-to-right direction. Add a FIXME
9855 comment for making that be controlled by a user option.

9857 bidi iterator. Save and restore the bidi_p flag.
9858 (pop_it): Iterate out of display property for string iteration as
9860 (iterate_out_of_display_property): Support iteration over strings.
9861 (handle_single_display_spec): Set up it->bidi_it for iteration
9862 over a display string, and call bidi_init_it.

9865 iterator for displaying display or overlay strings.
9866 (forward_to_next_line_start): Don't use the shortcut if
9868 (back_to_previous_visible_line_start): If handle_display_prop
9869 pushed the iterator stack, restore the internal state of the bidi
9870 iterator by calling bidi_pop_it same number of times.
9871 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9872 and we are bidi-iterating, don't decrement the iterator position;
9873 instead, set the first_elt flag in the bidi iterator, to produce
9875 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9876 (push_display_prop): xassert that we are iterating a buffer.
9877 (push_it, pop_it): Save and restore paragraph_embedding member.
9878 (handle_single_display_spec, next_overlay_string)

9881 correctly. Don't assume unibyte strings are not bidi-reordered.
9882 (compute_display_string_pos)
9883 (compute_display_string_end): Fix handling the case of C string.
9884 (push_it, pop_it): Save and restore from_disp_prop_p.
9885 (handle_single_display_spec, push_display_prop): Set the
9886 from_disp_prop_p flag.
9887 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9893 (handle_single_display_spec, get_overlay_strings_1)
9894 (push_display_prop): Fix initialization of paragraph direction for
9895 string when that of the parent object is not yet determined.

9909 (back_to_previous_visible_line_start, reseat_1)
9910 (init_iterator): Empty the bidi cache "stack".
9911 (move_it_in_display_line_to): If iterator ended up at

9914 motion in bidi-reordered lines.
9915 (move_it_in_display_line_to): Record prev_method and prev_pos

9933 (bidi_level_of_next_char, bidi_find_other_level_edge)
9934 (bidi_move_to_visually_next): Compare cache index with
9935 bidi_cache_start rather than with zero.
9936 (bidi_fetch_char): Accept new argument STRING; all callers
9937 changed. Support iteration over a string. Support strings with
9938 display properties. Support unibyte strings. Fix the type of
9939 `len' according to what STRING_CHAR_AND_LENGTH expects.
9940 (bidi_paragraph_init, bidi_resolve_explicit_1)

9956 the test for valid cached positions. Fix the logic for looking up
9957 the sentinel state in the cache. GCPRO the Lisp string we are
9959 (bidi_push_it, bidi_pop_it): New functions.
9960 (bidi_initialize): Initialize the bidi cache start stack pointer.

10035 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
10037 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
10038 The old code sometimes used this field without initializing it.
10040 * alloc.c (gc_sweep): Don't read past end of array.
10041 In theory, the old code could also have corrupted Emacs internals,
10042 though it'd be very unlikely.

10307 This isn't true in general, and it's particularly not true
10308 if Emacs is configured with --with-wide-int.
10309 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

10346 Random fixes. E.g., (random) never returned negative values.
10347 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10348 subseconds part to the entropy, as that's a bit more random.
10349 Prefer signed to unsigned, since the signedness doesn't matter and
10350 in general we prefer signed. When given a limit, use a
10351 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10352 latter isn't right if USE_2_TAGS_FOR_INTS.
10353 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10354 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10366 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
10367 This is more efficient than Ffile_directory_p and avoids a minor race.
10369 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
10371 * buffer.c (Foverlay_put): Say what the return value is
10374 * fileio.c (barf_or_query_if_file_exists): Check first if the file
10375 is a directory before asking whether to use the file name

10378 error be more correct.
10380 * fns.c (Frequire): Remove the mention of the .gz files, since
10381 that's installation-specific, but keep the mention of

10397 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
10398 Also (re)move comments that are misplaced or no longer relevant.

10427 * lread.c (syms_of_lread): Mention single symbols defined by

10460 minibuffer-local-filename-must-match-map to Elisp.
10461 (syms_of_keymap): Defsubr make-composed-keymap.
10462 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
10463 (parse_menu_item): Trivial simplification.
10465 2011-07-01 Glenn Morris <rgm@gnu.org>
10467 * Makefile.in (SETTINGS_LIBS): Fix typo.

10499 * eval.c (struct backtrace): Simplify and port the data structure.
10500 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10501 signed bit field, as this assumption is not portable and it makes
10502 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10503 "char debug_on_exit : 1" as this is not portable either; instead,
10504 use the portable "unsigned int debug_on_exit : 1". Remove unused
10505 member evalargs. Remove obsolete comments about cc bombing out.
10507 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
10509 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

10575 (emacs_fixed_new): Set priv->f to argument.
10576 (emacs_fixed_get_preferred_width)
10577 (emacs_fixed_get_preferred_height): Use min_width/height from
10578 frames size_hint to set minimum and natural (Bug#8919).
10579 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
10580 and use min_width/height from frames size_hint to set
10581 min_width/height (Bug#8919).
10583 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

10601 Use gnulib's dup2 module instead of rolling our own.
10602 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

10669 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10671 Integer and buffer overflow fixes (Bug#8873).
10673 * print.c (printchar, strout): Check for string overflow.
10674 (PRINTPREPARE, printchar, strout):
10675 Don't set size unless allocation succeeds.
10677 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10678 for sizes. Check for string overflow more accurately.
10679 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10681 * macros.c: Integer and buffer overflow fixes.
10682 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10683 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

10687 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10689 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10691 * lread.c: Integer overflow fixes.
10692 (read_integer): Radix is now EMACS_INT, not int,
10693 to improve quality of diagnostics for out-of-range radices.
10694 Calculate buffer size correctly for out-of-range radices.
10695 (read1): Check for integer overflow in radices, and in
10696 read-circle numbers.
10697 (read_escape): Avoid int overflow.
10698 (Fload, openp, read_buffer_size, read1)
10699 (substitute_object_recurse, read_vector, read_list, map_obarray):
10700 Use ptrdiff_t, not int, for sizes.

10715 2011-06-22 Leo Liu <sdl.web@gmail.com>
10717 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10718 Move to minibuffer.el.
10720 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10722 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10723 The following patches are for when GLYPH_DEBUG && !XASSERT.
10724 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10725 * dispnew.c (flush_stdout):
10726 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10727 Mark as externally visible.
10728 * dispnew.c (check_window_matrix_pointers): Now static.
10729 * dispnew.c (window_to_frame_vpos):
10730 * xfns.c (unwind_create_frame):
10731 * xterm.c (x_check_font): Remove unused local.
10732 * scroll.c (CHECK_BOUNDS):
10733 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10734 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10735 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10736 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10737 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10739 (debug_method_add): Use va_list and vsprintf rather than relying
10740 on undefined behavior with wrong number of arguments.
10741 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10742 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10743 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10744 since we're not interested in debugging glyphs with old libraries.
10745 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10746 GCC 4.6.0's static checking.
10748 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10750 Integer overflow and signedness fixes (Bug#8873).

10759 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10760 (x_create_bitmap_from_xpm_data):
10761 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10762 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10764 * xfaces.c (load_pixmap):
10765 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10766 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10767 (.bitmaps_last, struct x_output.icon_bitmap):
10768 Use ptrdiff_t, not int, for bitmap indexes.
10769 (x_allocate_bitmap_record): Check for size overflow.
10770 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10772 Use ptrdiff_t, not int, for overlay counts.
10773 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10774 * editfns.c (overlays_around, get_pos_property):
10775 * textprop.c (get_char_property_and_overlay):
10776 * xdisp.c (next_overlay_change, note_mouse_highlight):
10777 * xfaces.c (face_at_buffer_position):
10778 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10779 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10780 (Fnext_overlay_change, Fprevious_overlay_change)
10781 (mouse_face_overlay_overlaps, Foverlays_in):
10782 Use ptrdiff_t, not int, for sizes.
10783 (overlays_at, overlays_in): Check for size-calculation overflow.
10785 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10787 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10788 (x_session_initialize): Do not assume string length fits in int.
10790 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10791 This is unlikely, but can occur if DPI is outlandish.
10793 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10794 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10796 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10797 * xrdb.c (magic_file_p, search_magic_path):
10798 Omit last arg SUFFIX; it was always 0. All callers changed.
10799 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10801 * xfont.c (xfont_match): Avoid need for strlen.
10803 * xfns.c: Don't assume strlen fits in int.

10806 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10807 not unsigned long, as we prefer signed integers. All callers changed.
10808 Detect integer overflow in repeat count.
10809 (message_dolog): Don't assume print length fits in 39 bytes.
10810 (display_mode_element): Don't assume strlen fits in int.
10812 * termcap.c: Don't assume sizes fit in int and never overflow.
10813 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10814 (gobble_line): Check for size-calculation overflow.
10816 * minibuf.c (Fread_buffer):
10817 * lread.c (intern, intern_c_string):
10818 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10819 Don't assume string length fits in int.

10831 * filelock.c: Fix some buffer overrun and integer overflow issues.
10832 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10833 Reformulate so as not to need the command string.
10834 Invoke gzip -cd rather than gunzip, as it's more portable.
10835 (lock_info_type, lock_file_1, lock_file):
10836 Don't assume pid_t and time_t fit in unsigned long.
10837 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10838 (current_lock_owner): Prefer signed type for sizes.
10839 Use memcpy, not strncpy, where memcpy is what is really wanted.
10840 Don't assume (via atoi) that time_t and pid_t fit in int.
10841 Check for time_t and/or pid_t out of range, e.g., via a network share.
10842 Don't alloca where an auto var works fine.
10844 * fileio.c: Fix some integer overflow issues.
10845 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10846 Don't assume string length fits in int.
10847 (directory_file_name): Don't assume string length fits in long.
10848 (make_temp_name): Don't assume pid fits in int, or that its print
10849 length is less than 20.
10851 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10853 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10855 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10857 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10858 We prefer signed integers, even for size calculations.
10860 * emacs.c: Don't assume string length fits in 'int'.
10861 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10862 (main): Don't invoke strlen when not needed.
10864 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

10867 * callproc.c (getenv_internal_1, getenv_internal)
10868 (Fgetenv_internal):
10869 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10871 * lread.c (invalid_syntax): Omit length argument.
10872 All uses changed. This doesn't fix a bug, but it simplifies the
10873 code away from its former Hollerith-constant appearance, and it's
10874 one less 'int' to worry about when looking at integer-overflow issues.
10875 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10877 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10878 This didn't break anything, but it didn't help either.
10879 It's confusing to put a bogus integer in a place where the actual
10880 value does not matter.
10881 (LIST_END_P): Remove unused macro and its bogus comment.
10882 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10884 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10885 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10887 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10888 We prefer signed types, and the value cannot exceed the EMACS_INT
10889 range anyway (because otherwise the length would not be representable).
10890 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10891 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10892 This avoids a GCC warning when WIDE_EMACS_INT.
10894 * indent.c (sane_tab_width): New function.
10895 (current_column, scan_for_column, Findent_to, position_indentation)
10896 (compute_motion): Use it. This is just for clarity.
10897 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10899 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10901 * lisp.h (lint_assume): New macro.
10902 * composite.c (composition_gstring_put_cache):
10903 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10905 * editfns.c, insdel.c:
10906 Omit unnecessary forward decls, to simplify future changes.
10908 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10910 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10912 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10913 Use much-faster test for byte-length change.
10914 Don't assume string byte-length fits in 'int'.
10915 Check that character arg fits in 'int'.
10916 (mapcar1): Declare byte as byte, for clarity.
10918 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10920 * fns.c (concat): Catch string overflow earlier.
10921 Do not rely on integer wraparound.
10923 * dispextern.h (struct it.overlay_strings_charpos)
10924 (struct it.selective): Now EMACS_INT, not int.
10925 * xdisp.c (forward_to_next_line_start)
10926 (back_to_previous_visible_line_start)
10927 (reseat_at_next_visible_line_start, next_element_from_buffer):
10928 Don't arbitrarily truncate the value of 'selective' to int.
10930 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10932 * composite.c: Don't truncate sizes to 'int'.
10933 (composition_gstring_p, composition_reseat_it)
10934 (composition_adjust_point): Use EMACS_INT, not int.
10935 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10936 not EMACS_UINT, for indexes.
10938 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10940 * buffer.c: Include <verify.h>.
10941 (struct sortvec.priority, struct sortstr.priority):
10942 Now EMACS_INT, not int.
10943 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10944 (struct sortstr.size, record_overlay_string)
10945 (struct sortstrlist.size, struct sortlist.used):
10946 Don't truncate size to int.
10947 (record_overlay_string): Check for size-calculation overflow.
10948 (init_buffer_once): Check at compile-time, not run-time.
10950 2011-06-22 Jim Meyering <meyering@redhat.com>
10952 Don't leak an XBM-image-sized buffer
10953 * image.c (xbm_load): Free the image buffer after using it.
10955 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10958 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10959 that Sun C diagnosed.
10960 * fns.c (secure_hash): Fix pointer signedness issue.
10961 * intervals.c (static_offset_intervals): New function.
10962 (offset_intervals): Use it.
10964 2011-06-21 Leo Liu <sdl.web@gmail.com>
10967 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10970 * fns.c (secure_hash): Rename from crypto_hash_function and change
10971 the first arg to accept symbols.
10972 (Fsecure_hash): New primitive.
10973 (syms_of_fns): New symbols.
10975 2011-06-20 Deniz Dogan <deniz@dogan.se>
10977 * process.c (Fset_process_buffer): Clarify return value in
10980 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10982 * dispnew.c (add_window_display_history): Use BVAR.
10984 * xdisp.c (debug_method_add): Use BVAR.
10985 (check_window_end, dump_glyph_matrix, dump_glyph)
10986 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10988 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10991 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10992 check till after the cache is created in init_frame_faces.
10994 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10996 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10998 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
11000 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
11001 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
11002 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
11004 Improve buffer-overflow checking (Bug#8873).
11005 * fileio.c (Finsert_file_contents):
11006 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
11007 Remove the old (too-loose) buffer overflow checks.
11008 They weren't needed, since make_gap checks for buffer overflow.
11009 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
11010 The old code merely checked for Emacs fixnum overflow, and relied
11011 on undefined (wraparound) behavior. The new code avoids undefined
11012 behavior, and also checks for ptrdiff_t and/or size_t overflow.
11014 * editfns.c (Finsert_char): Don't dump core with very negative counts.
11015 Tune. Don't use wider integers than needed. Don't use alloca.
11016 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
11018 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
11020 * insdel.c, lisp.h (buffer_overflow): New function.
11021 (insert_from_buffer_1, replace_range, replace_range_2):
11022 * insdel.c (make_gap_larger):
11023 * editfns.c (Finsert_char):
11024 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
11026 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
11028 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
11030 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
11032 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
11033 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
11035 * fileio.c: Don't assume EMACS_INT fits in off_t.
11036 (emacs_lseek): New static function.
11037 (Finsert_file_contents, Fwrite_region): Use it.
11038 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
11040 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
11042 * fns.c: Don't overflow int when computing a list length.
11043 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
11044 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
11045 truncation on 64-bit hosts. Check for QUIT every
11046 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
11047 faster and is responsive enough.
11048 (Flength): Report an error instead of overflowing an integer.
11049 (Fsafe_length): Return a float if the value is not representable
11050 as a fixnum. This shouldn't happen except in contrived situations.
11051 (Fnthcdr, Fsort): Don't assume list length fits in int.
11052 (Fcopy_sequence): Don't assume vector length fits in int.
11054 * alloc.c: Check that resized vectors' lengths fit in fixnums.
11055 (header_size, word_size): New constants.
11056 (allocate_vectorlike): Don't check size overflow here.
11057 (allocate_vector): Check it here instead, since this is the only
11058 caller of allocate_vectorlike that could cause overflow.
11059 Check that the new vector's length is representable as a fixnum.
11061 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11062 The previous code was bogus. For example, next_almost_prime (32)
11063 returned 39, which is undesirable as it is a multiple of 3; and
11064 next_almost_prime (24) returned 25, which is a multiple of 5 so
11065 why was the code bothering to check for multiples of 7?
11067 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11069 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11071 Variadic C functions now count arguments with ptrdiff_t.
11072 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11073 Back then I didn't know that the Emacs coding style prefers signed int.
11074 Also, in the meantime I found a few more instances where arguments
11075 were being counted with int, which may truncate counts on 64-bit
11076 machines, or EMACS_INT, which may be unnecessarily wide.
11077 * lisp.h (struct Lisp_Subr.function.aMANY)
11078 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11079 Arg counts are now ptrdiff_t, not size_t.
11080 All variadic functions and their callers changed accordingly.
11081 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11082 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11083 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11084 * callint.c (Fcall_interactively): Check arg count for overflow,
11085 to avoid potential buffer overrun. Use signed char, not 'int',
11086 for 'varies' array, so that we needn't bother to check its size
11087 calculation for overflow.
11088 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11089 * eval.c (apply_lambda):
11090 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11091 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11092 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11094 * callint.c (Fcall_interactively): Don't use index var as event count.
11096 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11097 * mem-limits.h (SIZE): Remove; no longer used.
11099 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11101 Remove unnecessary casts.
11102 * xterm.c (x_term_init):
11103 * xfns.c (x_set_border_pixel):
11104 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11105 These aren't needed now that we assume ANSI C.
11107 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11108 It's more likely to cause problems (due to unsigned overflow)
11111 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11113 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11115 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11117 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11119 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11121 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11123 GLYPH_CODE_FACE returns EMACS_INT, not int.
11124 * dispextern.h (merge_faces):
11125 * xfaces.c (merge_faces):
11126 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11127 Don't assume EMACS_INT fits in int.
11129 * character.h (CHAR_VALID_P): Remove unused parameter.
11130 * fontset.c, lisp.h, xdisp.c: All uses changed.
11132 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11134 * fns.c (concat): Minor tuning based on overflow analysis.
11135 This doesn't fix any bugs. Use int to hold character, instead
11136 of constantly refetching from Emacs object. Use XFASTINT, not
11137 XINT, for value known to be a character. Don't bother comparing
11138 a single byte to 0400, as it's always less.
11140 * floatfns.c (Fexpt):
11141 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11143 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11146 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11148 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11149 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11150 incorrectly succeed when S was a string, because 4294967386 was
11151 truncated before it was used.
11153 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11154 Otherwise, an out-of-range integer could cause undefined behavior
11157 * composite.c: Use int, not EMACS_INT, for characters.
11158 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11159 EMACS_INT, for values that are known to be in character range.
11160 This doesn't fix any bugs but is the usual style inside Emacs and
11161 may generate better code on 32-bit machines.
11163 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11164 This is for reasons similar to the recent CHAR_STRING fix.
11165 * charset.c (Fencode_char): Check that character arg is actually
11166 a character. Pass an int to ENCODE_CHAR.
11167 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11168 wider than 'int', as a compile-time check to prevent future regressions
11171 * character.c (char_string): Remove unnecessary casts.
11173 Make sure a 64-bit char is never passed to CHAR_STRING.
11174 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11175 by silently ignoring the top 32 bits, allowing some values
11176 that were far too large to be valid characters.
11177 * character.h: Include <verify.h>.
11178 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11179 arguments are no wider than unsigned, as a compile-time check
11180 to prevent future regressions in this area.
11182 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11183 (Fsubst_char_in_region):
11185 * xdisp.c (decode_mode_spec_coding):
11186 Adjust to CHAR_STRING's new requirement.
11187 * editfns.c (Finsert_char, Fsubst_char_in_region):
11188 * fns.c (concat): Check that character args are actually
11189 characters. Without this test, these functions did the wrong
11190 thing with wildly out-of-range values on 64-bit hosts.
11192 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11193 These casts should not be needed on 32-bit hosts, either.
11194 * keyboard.c (read_char):
11195 * lread.c (Fload): Remove casts to unsigned.
11197 * lisp.h (UNSIGNED_CMP): New macro.
11198 This fixes comparison bugs on 64-bit hosts.
11199 (ASCII_CHAR_P): Use it.
11200 * casefiddle.c (casify_object):
11201 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11202 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11203 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11204 * dispextern.h (FACE_FROM_ID):
11205 * keyboard.c (read_char): Use UNSIGNED_CMP.
11207 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11208 not to EMACS_INT, to avoid GCC warning.
11210 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11212 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11213 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11214 isn't needed on 32-bit machines.
11216 * buffer.c (Fgenerate_new_buffer_name):
11217 Use EMACS_INT for count, not int.
11218 (advance_to_char_boundary): Return EMACS_INT, not int.
11220 * data.c (Qcompiled_function): Now static.
11222 * window.c (window_body_lines): Now static.
11224 * image.c (gif_load): Rename local to avoid shadowing.
11226 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11227 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11228 * alloc.c (make_save_value): Integer argument is now of type
11229 ptrdiff_t, not int.
11230 (mark_object): Use ptrdiff_t, not int.
11231 * lisp.h (pD): New macro.
11232 * print.c (print_object): Use it.
11234 * alloc.c: Use EMACS_INT, not int, to count objects.
11235 (total_conses, total_markers, total_symbols, total_vector_size)
11236 (total_free_conses, total_free_markers, total_free_symbols)
11237 (total_free_floats, total_floats, total_free_intervals)
11238 (total_intervals, total_strings, total_free_strings):
11239 Now EMACS_INT, not int. All uses changed.
11240 (Fgarbage_collect): Compute overall total using a double, so that
11241 integer overflow is less likely to be a problem. Check for overflow
11242 when converting back to an integer.
11243 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11244 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11245 These were 'int' variables that could overflow on 64-bit hosts;
11246 they were never used, so remove them instead of repairing them.
11247 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11248 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
11249 Previously, this ceilinged at INT_MAX, but that doesn't work on
11251 (allocate_pseudovector): Don't use EMACS_INT when int would do.
11253 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
11254 (allocate_vectorlike): Check for ptrdiff_t overflow.
11255 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
11256 when a (possibly-narrower) signed value would do just as well.
11257 We prefer using signed arithmetic, to avoid comparison confusion.
11259 * alloc.c: Catch some string size overflows that we were missing.
11260 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
11261 for convenience in STRING_BYTES_MAX.
11262 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11263 The definition here is exact; the one in lisp.h was approximate.
11264 (allocate_string_data): Check for string overflow. This catches
11265 some instances we weren't catching before. Also, it catches
11266 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11267 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11268 and ptrdiff_t and EMACS_INT are both 64 bits.
11270 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11271 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
11272 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
11274 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
11276 * alloc.c (Fmake_string): Check for out-of-range init.
11278 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
11280 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
11282 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
11284 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
11285 xg_get_default_scrollbar_width.
11287 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
11288 (int_gtk_range_get_value): Move to the scroll bar part of the file.
11289 (style_changed_cb): Call update_theme_scrollbar_width and call
11290 x_set_scroll_bar_default_width and xg_frame_set_char_size for
11291 all frames (Bug#8505).
11292 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
11293 Call gtk_window_set_resizable if HAVE_GTK3.
11294 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
11295 and height if HAVE_GTK3 (Bug#8505).
11296 (scroll_bar_width_for_theme): New variable.
11297 (update_theme_scrollbar_width): New function.
11298 (xg_get_default_scrollbar_width): Move code to
11299 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
11300 (xg_initialize): Call update_theme_scrollbar_width.
11302 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
11304 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
11306 2011-06-12 Martin Rudalics <rudalics@gmx.at>
11308 * frame.c (make_frame): Call other_buffer_safely instead of
11311 * window.c (temp_output_buffer_show): Call display_buffer with
11312 second argument Vtemp_buffer_show_specifiers and reset latter
11313 immediately after the call.
11314 (Vtemp_buffer_show_specifiers): New variable.
11315 (auto_window_vscroll_p, next_screen_context_lines)
11316 (Vscroll_preserve_screen_position): Remove leading asterisks from
11319 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
11321 Fix minor problems found by GCC 4.6.0 static checking.
11322 * buffer.c (Qclone_number): Remove for now, as it's unused.
11323 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
11324 (record_buffer): Remove unused local.
11325 * frame.c (other_visible_frames, frame_buffer_list): Now static.
11326 (set_frame_buffer_list): Remove; unused.
11327 * frame.h (other_visible_frames): Remove decl.
11328 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
11329 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
11330 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only

11777 Do not assume that spare memory exists; that assumption is valid
11778 only if SYSTEM_MALLOC.
11779 (LARGE_REQUEST): New macro, so that the issue of large requests
11780 is separated from the issue of spare memory.
11782 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
11784 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

11799 min width by calling x_set_scroll_bar_default_width (Bug#8505).
11801 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
11803 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
11805 2011-06-04 Chong Yidong <cyd@stupidchicken.com>
11807 * xselect.c (x_clipboard_manager_save): Remove redundant arg.
11808 (x_clipboard_manager_save): Add return value.
11809 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
11810 New error handlers.
11811 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
11812 Obey Vx_select_enable_clipboard_manager. Catch errors in
11813 x_clipboard_manager_save (Bug#8779).
11814 (Vx_select_enable_clipboard_manager): New variable.
11815 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
11817 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
11819 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
11821 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11823 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
11824 in the current matrix if keep_current_p is non-zero.

11828 * bidi.c (bidi_level_of_next_char): Fix last change.
11830 2011-06-03 Eli Zaretskii <eliz@gnu.org>
11832 Support bidi reordering of text covered by display properties.
11834 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
11835 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
11836 (bidi_cache_search, bidi_cache_iterator_state)
11837 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11838 (bidi_level_of_next_char, bidi_move_to_visually_next):
11839 Support character positions inside a run of characters covered by a
11841 (bidi_paragraph_init, bidi_resolve_explicit_1)
11842 (bidi_level_of_next_char): Call bidi_fetch_char and
11843 bidi_fetch_char_advance instead of FETCH_CHAR and
11844 FETCH_CHAR_ADVANCE.
11845 (bidi_init_it): Initialize new members.
11846 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11848 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11849 instead of using explicit *_CHAR codes.
11850 (bidi_resolve_explicit, bidi_resolve_weak):
11851 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11852 bidirectional text is supported only in multibyte buffers.
11853 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11854 it to initialize the frame_window_p member of struct bidi_it.
11855 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11856 (bidi_resolve_explicit, bidi_resolve_weak)

11858 bidi_it->nchars is non-positive.
11859 (bidi_level_of_next_char): Don't try to lookup the cache for the
11860 next/previous character if nothing is cached there yet, or if we
11861 were just reseat()'ed to a new position.
11863 * xdisp.c (set_cursor_from_row): Set start and stop points
11864 according to the row's direction when priming the loop that looks
11865 for the glyph on which to display cursor.
11866 (single_display_spec_intangible_p): Function deleted.
11867 (display_prop_intangible_p): Reimplement to call
11868 handle_display_spec instead of single_display_spec_intangible_p.
11869 Accept 3 additional arguments needed by handle_display_spec.
11870 This fixes incorrect cursor motion across display property with complex
11871 values: lists, `(when COND...)' forms, etc.
11872 (single_display_spec_string_p): Support property values that are
11873 lists with the argument STRING its top-level element.
11874 (display_prop_string_p): Fix the condition for processing a
11875 property that is a list to be consistent with handle_display_spec.
11876 (handle_display_spec): New function, refactored from the
11877 last portion of handle_display_prop.
11878 (compute_display_string_pos): Accept additional argument
11879 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11880 value of a `display' property is a "replacing spec".
11881 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11882 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11883 the display property, but just return a value indicating whether
11884 the display property will replace the characters it covers.
11885 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11886 frame_window_p members of struct bidi_it.
11887 (compute_display_string_pos, compute_display_string_end):
11889 (push_it): Accept second argument POSITION, where pop_it should
11890 jump to continue iteration.
11891 (reseat_1): Initialize bidi_it.disp_pos.
11893 * keyboard.c (adjust_point_for_property): Adjust the call to
11894 display_prop_intangible_p to its new signature.
11896 * dispextern.h (struct bidi_it): New member frame_window_p.
11897 (bidi_init_it): Update prototypes.
11898 (display_prop_intangible_p): Update prototype.
11899 (compute_display_string_pos, compute_display_string_end):
11900 Declare prototypes.
11901 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11904 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11906 Malloc failure behavior now depends on size of allocation.
11907 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11908 * lisp.h: Change signatures accordingly.
11909 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11910 All callers changed. (Bug#8762)
11912 * gnutls.c: Use Emacs's memory allocators.
11913 Without this change, the gnutls library would invoke malloc etc.
11914 directly, which causes problems on non-SYNC_INPUT hosts, and which
11915 runs afoul of improving memory_full behavior. (Bug#8761)
11916 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11917 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11918 xfree instead of the default malloc, realloc, free.
11919 (Fgnutls_boot): No need to check for memory allocation failure,
11920 since xmalloc does that for us.
11922 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11923 * category.c (hash_get_category_set):
11924 * ccl.c (ccl_driver):
11925 * charset.c (Fdefine_charset_internal):
11926 * charset.h (struct charset.hash_index):
11927 * composite.c (get_composition_id, gstring_lookup_cache)
11928 (composition_gstring_put_cache):
11929 * composite.h (struct composition.hash_index):
11930 * dispextern.h (struct image.hash):
11931 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11932 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
11933 (hashfn_equal, hashfn_user_defined, make_hash_table)
11934 (maybe_resize_hash_table, hash_lookup, hash_put)
11935 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11936 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11937 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11938 * image.c (make_image, search_image_cache, lookup_image)
11939 (xpm_put_color_table_h):
11940 * lisp.h (struct Lisp_Hash_Table):
11941 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11942 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11943 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11944 * alloc.c (allocate_vectorlike):
11945 Check for overflow in vector size calculations.
11946 * ccl.c (ccl_driver):
11947 Check for overflow when converting EMACS_INT to int.
11948 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11949 need to be updated by these changes.
11950 * fns.c (make_hash_table, maybe_resize_hash_table):
11951 Check for integer overflow with large hash tables.
11952 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11953 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11954 (SXHASH_REDUCE): New macro.
11955 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11956 Use it instead of discarding useful hash info with large hash values.
11957 (sxhash_float): New function.
11958 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11959 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11960 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11961 Rewrite to use FIXNUM_BITS, as this simplifies things.
11962 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11963 Adjust signatures to match updated version of code.
11964 (consing_since_gc): Now EMACS_INT, since a single hash table can
11965 use more than INT_MAX bytes.
11967 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11969 Make it possible to build with GCC-4.6+ -O2 -flto.
11971 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11973 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11975 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11976 Call minibuffer-inactive-mode.
11978 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11980 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11981 Update dependencies.
11983 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11985 * data.c (init_data): Remove code for UTS, this system is not
11988 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11990 Don't force ./temacs to start in terminal mode.
11992 * frame.c (make_initial_frame): Initialize faces in all cases, not
11993 only when CANNOT_DUMP is defined.
11994 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11996 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11998 * dispnew.c (add_window_display_history): Use const for the string
11999 pointer. Remove declaration, not needed.
12001 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12003 Use 'inline', not 'INLINE'.
12004 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
12005 * alloc.c, fontset.c (INLINE): Remove.
12006 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
12007 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
12008 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
12009 * gmalloc.c (register_heapinfo): Use inline unconditionally.
12010 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
12012 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12014 Make it possible to run ./temacs.
12016 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
12017 syms_of_callproc does the same thing. Remove test for
12018 "initialized", do it in the caller.
12019 * emacs.c (main): Avoid calling set_initial_environment when dumping.
12021 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
12023 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
12024 (read_minibuf): Use get_minibuffer.
12025 (syms_of_minibuf): Use DEFSYM.
12026 (Qmetadata): New var.
12027 * data.c (Qbuffer): Don't make it static.
12028 (syms_of_data): Use DEFSYM.
12030 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12032 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
12033 (CCL_CODE_MIN): New macro.
12035 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
12037 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
12039 * eval.c (Qdebug): Now static.
12040 * lisp.h (Qdebug): Remove decl. This reverts a part of the
12041 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
12042 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
12044 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12046 * image.c: Various fixes to ImageMagick code comments.
12047 (Fimagemagick_types): Doc fix.
12049 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
12051 Minor fixes prompted by GCC 4.6.0 warnings.
12053 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12055 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12056 (x_clipboard_manager_save_all): Move extern decl to ...
12057 * xterm.h: ... here, so that it can be checked for consistency.
12059 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12061 * xselect.c (x_clipboard_manager_save_frame)
12062 (x_clipboard_manager_save_all): New functions.
12063 (Fx_clipboard_manager_save): Lisp function deleted.
12065 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12066 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12068 * xterm.h: Update prototype.
12070 2011-05-28 William Xu <william.xwl@gmail.com>
12072 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12073 exiting (Bug#8239).
12075 2011-05-28 Jim Meyering <meyering@redhat.com>
12077 Avoid a sign-extension bug in crypto_hash_function.
12078 * fns.c (to_uchar): Define.
12079 (crypto_hash_function): Use it to convert some newly-signed
12080 variables to unsigned, to avoid sign-extension bugs. For example,
12081 without this change, (md5 "truc") would evaluate to
12082 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12083 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12084 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12086 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12088 Integer overflow fixes.
12090 * dbusbind.c: Serial number integer overflow fixes.
12091 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12092 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12093 to hold a serial number that is too large for a fixnum.
12094 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12095 Check for serial numbers out of range. Decode any serial number
12096 that was so large that it became a float. (Bug#8722)
12098 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12099 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12100 Use XFASTINT rather than XUINT when numbers are nonnegative.
12101 (xd_append_arg, Fdbus_method_return_internal):
12102 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12103 arguments, check that Lisp number is nonnegative, rather than
12104 silently wrapping negative numbers around. (Bug#8722)
12105 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12108 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12110 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12112 ccl: Add integer overflow checks.
12113 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12114 (IN_INT_RANGE): New macros.
12115 (ccl_driver): Use them to check for integer overflow when
12116 decoding a CCL program. Many of the new checks are whether XINT (x)
12117 fits in int; it doesn't always, on 64-bit hosts. The new version
12118 doesn't catch all possible integer overflows, but it's an
12119 improvement. (Bug#8719)
12121 * alloc.c (make_event_array): Use XINT, not XUINT.
12122 There's no need for unsigned here.
12124 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12125 This follows up to the 2011-05-06 change that substituted uintptr_t
12126 for EMACS_INT. This case wasn't caught back then.
12128 Rework Fformat to avoid integer overflow issues.
12129 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12130 now (part of C89). Include <verify.h>.
12131 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12132 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12133 (Fformat): Avoid the prepass trying to compute sizes; it was only
12134 approximate and thus did not catch overflow reliably. Instead, walk
12135 through the format just once, formatting and computing sizes as we go,
12136 checking for integer overflow at every step, and allocating a larger
12137 buffer as needed. Keep track separately whether the format is
12138 multibyte. Keep only the most-recently calculated precision, rather
12139 than them all. Record whether each argument has been converted to
12140 string. Use EMACS_INT, not int, for byte and char and arg counts.
12141 Support field widths and precisions larger than INT_MAX. Avoid
12142 sprintf's undefined behavior with conversion specifications such as %#d
12143 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12144 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12145 formatting out-of-range floating point numbers with int
12146 formats. (Bug#8668)
12148 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12150 * data.c: Avoid integer truncation in expressions involving floats.
12151 * data.c: Include <intprops.h>.
12152 (arith_driver): When there's an integer overflow in an expression
12153 involving floating point, convert the integers to floating point
12154 so that the resulting value does not suffer from catastrophic
12155 integer truncation. For example, on a 64-bit host (* 4
12156 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12157 Do not rely on undefined behavior after integer overflow.
12159 merge count_size_as_multibyte, parse_str_to_multibyte
12160 * character.c, character.h (count_size_as_multibyte):
12161 Rename from parse_str_to_multibyte; all uses changed.
12162 Check for integer overflow.
12163 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12164 since it's now a duplicate of the other. This is more of
12165 a character than a buffer op, so better that it's in character.c.
12166 * fns.c, print.c: Adjust to above changes.
12168 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12170 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12172 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12174 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12175 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12176 (x_clipboard_manager_save): Now static.
12177 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12179 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12180 (crypto_hash_function): Now static.
12181 Fix pointer signedness problems. Avoid unnecessary initializations.
12183 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12185 * termhooks.h (Vselection_alist): Make it terminal-local.
12187 * terminal.c (create_terminal): Initialize it.
12189 * xselect.c: Support for clipboard managers.
12190 (Vselection_alist): Move to termhooks.h as terminal-local var.
12191 (LOCAL_SELECTION): New macro.
12192 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12193 (symbol_to_x_atom): Remove gratuitous arg.
12194 (x_handle_selection_request, lisp_data_to_selection_data)
12195 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12196 (x_own_selection, x_get_local_selection, x_convert_selection):
12197 New arg, specifying work frame. Use terminal-local Vselection_alist.
12198 (some_frame_on_display): Delete unused function.
12199 (Fx_own_selection_internal, Fx_get_selection_internal)
12200 (Fx_disown_selection_internal, Fx_selection_owner_p)
12201 (Fx_selection_exists_p): New optional frame arg.
12202 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12203 (x_handle_selection_clear): Don't treat other terminals with the
12204 same keyboard specially. Use the terminal-local Vselection_alist.
12205 (x_clear_frame_selections): Use Frun_hook_with_args.
12207 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12209 * xterm.h: Add support for those atoms.
12211 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12213 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12214 (converted_selections, conversion_fail_tag): New global variables.
12215 (x_selection_request_lisp_error): Free the above.
12216 (x_get_local_selection): Remove unnecessary code.
12217 (x_reply_selection_request): Args changed; handle arbitrary array
12218 of converted selections stored in converted_selections.
12219 Separate the XChangeProperty and SelectionNotify steps.
12220 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12221 (x_convert_selection): New function.
12222 (x_handle_selection_event): Simplify.
12223 (x_get_foreign_selection): Don't ignore incoming requests while
12224 waiting for an answer; this will fail when we implement
12225 SAVE_TARGETS, and seems unnecessary anyway.
12226 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12227 (Vx_sent_selection_functions): Doc fix.
12229 2011-05-26 Leo Liu <sdl.web@gmail.com>
12231 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12233 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12235 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12237 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12238 for fringe update if it has periodic bitmap.
12239 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12240 and fringe_bitmap_periodic_p.
12242 * fringe.c (get_fringe_bitmap_data): New function.
12243 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12244 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12245 row. Mark glyph row for fringe update if periodicity changed.
12247 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12248 for fringe update unless it has periodic bitmap.
12250 2011-05-25 Kenichi Handa <handa@m17n.org>
12252 * xdisp.c (get_next_display_element): Set correct it->face_id for
12253 a static composition.
12255 2011-05-24 Leo Liu <sdl.web@gmail.com>
12258 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12260 * fns.c (crypto_hash_function, Fsha1): New function.
12261 (Fmd5): Use crypto_hash_function.
12262 (syms_of_fns): Add Ssha1.
12264 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12266 * gnutls.c: Remove unused macros.
12267 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12268 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12269 Remove macros that are defined and never used.
12270 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12272 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12274 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12275 (Fx_get_selection_internal): Minor cleanup.
12276 (Fx_own_selection_internal): Rename arguments for consistency with
12279 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12281 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12283 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12285 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12287 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12289 * dispnew.c (scrolling_window): Don't exclude the case that the
12290 last enabled row in the desired matrix touches the bottom boundary.
12292 2011-05-21 Glenn Morris <rgm@gnu.org>
12294 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12295 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12296 and add some more files.
12298 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12300 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12301 report_file_error introduced by the change from 2011-05-07.
12303 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12305 * systime.h (Time): Define only if emacs is defined.
12306 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12307 where the include path doesn't have X11/X.h by default. See
12308 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12310 2011-05-20 Kenichi Handa <handa@m17n.org>
12312 * composite.c (find_automatic_composition): Fix previous change.
12314 2011-05-20 Glenn Morris <rgm@gnu.org>
12316 * lisp.mk: New file, split from Makefile.in.
12317 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12318 (shortlisp): Remove.
12319 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12321 2011-05-19 Glenn Morris <rgm@gnu.org>
12323 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12324 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12325 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12326 (lisp): Set the order to that of loadup.el.
12327 (shortlisp): Make it a copy of $lisp.
12328 (SOME_MACHINE_LISP): Remove.
12329 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12330 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12332 2011-05-18 Kenichi Handa <handa@m17n.org>
12334 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12335 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12336 (find_automatic_composition): Mostly rewrite for efficiency.
12338 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12340 * makefile.w32-in: Update dependencies.
12342 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12344 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12345 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12347 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12349 Fix some integer overflow issues, such as string length overflow.
12351 * insdel.c (count_size_as_multibyte): Check for string overflow.
12353 * character.c (lisp_string_width): Check for string overflow.
12354 Use EMACS_INT, not int, for string indexes and lengths; in
12355 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12356 the resulting string length overflows an EMACS_INT; instead,
12357 report a string overflow if no precision given. When checking for
12358 precision exhaustion, use a check that cannot possibly have
12359 integer overflow. (Bug#8675)
12360 * character.h (lisp_string_width): Adjust to new signature.
12362 * alloc.c (string_overflow): New function.
12363 (Fmake_string): Use it. This doesn't change behavior, but saves
12364 a few bytes and will simplify future changes.
12365 * character.c (string_escape_byte8): Likewise.
12366 * lisp.h (string_overflow): New decl.
12368 Fixups, following up to the user-interface timestamp change.
12369 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12370 for UI timestamps, instead of unsigned long.
12371 * msdos.c (mouse_get_pos): Likewise.
12372 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12373 * w32gui.h (Time): Define by including "systime.h" rather than by
12374 declaring it ourselves. (Bug#8664)
12376 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12377 * image.c (clear_image_cache): Likewise.
12379 * term.c (term_mouse_position): Don't assume time_t wraparound.
12381 Be more systematic about user-interface timestamps.
12382 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12383 and sometimes 'EMACS_UINT', to represent these timestamps.
12384 This change causes it to use 'Time' uniformly, as that's what X uses.
12385 This makes the code easier to follow, and makes it easier to catch
12386 integer overflow bugs such as Bug#8664.
12387 * frame.c (Fmouse_position, Fmouse_pixel_position):
12388 Use Time, not unsigned long, for user-interface timestamps.
12389 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12390 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12391 * keyboard.h (last_event_timestamp): Likewise.
12392 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12393 * menu.h (xmenu_show): Likewise.
12394 * term.c (term_mouse_position): Likewise.
12395 * termhooks.h (struct input_event.timestamp): Likewise.
12396 (struct terminal.mouse_position_hook): Likewise.
12397 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12398 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12399 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12400 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12401 what it was before.
12402 * menu.h, termhooks.h: Include "systime.h", for Time.
12404 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12405 Don't assume that the difference between two unsigned long values
12406 can fit into an integer. At this point, we know button_down_time
12407 <= event->timestamp, so the difference must be nonnegative, so
12408 there's no need to cast the result if double-click-time is
12409 nonnegative, as it should be; check that it's nonnegative, just in
12410 case. This bug is triggered when events are more than 2**31 ms
12411 apart (about 25 days). (Bug#8664)
12413 * xselect.c (last_event_timestamp): Remove duplicate decl.
12414 (x_own_selection): Remove needless cast to unsigned long.
12416 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12417 that always fit in int. Use a sentinel instead of a counter, to
12418 avoid a temp and to allay GCC's concerns about possible int overflow.
12419 * frame.h (struct frame): Use int for menu_bar_items_used
12420 instead of EMACS_INT, since it always fits in int.
12422 * menu.c (grow_menu_items): Check for int overflow.
12424 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12426 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12427 Before, the code was not consistent. These values cannot exceed
12428 2**31 - 1 so there's no need to make them unsigned.
12429 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12430 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12431 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12433 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12435 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12436 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12437 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12438 presumably because the widths might not match.
12440 * window.c (size_window): Avoid needless test at loop start.
12442 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12444 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12446 2011-05-12 Drew Adams <drew.adams@oracle.com>
12448 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12450 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12452 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12453 `width' to `bar_area_x' and `bar_area_width', respectively.
12454 (x_scroll_run): Take account of fringe background extension.
12456 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12457 Rename local vars `left' and `width' to `bar_area_x' and
12458 `bar_area_width', respectively.
12459 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12460 background extension.
12462 2011-05-10 Jim Meyering <meyering@redhat.com>
12464 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12466 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12468 * image.c (Finit_image_library): Return t for built-in image types,
12469 like pbm and xbm. (Bug#8640)
12471 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12473 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12475 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12477 * w32console.c (Fset_screen_color): Doc fix.
12478 (Fget_screen_color): New function.
12479 (syms_of_ntterm): Defsubr it.
12481 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12482 unlink the temporary file if Fcall_process didn't create it in the
12484 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12485 child process will be redirected to a file specified with `:file'.
12486 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12487 cue to call_process_cleanup not to close that handle.
12489 2011-05-07 Ben Key <bkey76@gmail.com>
12491 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12492 one of two shell specific rules, either bootstrap-temacs-CMD or
12493 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12494 to the previous implementation of the bootstrap-temacs rule.
12495 The bootstrap-temacs-CMD rule is similar to the previous
12496 implementation of the bootstrap-temacs rule except that it
12497 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12500 These changes, along with some changes to nt/configure.bat,
12501 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12502 earlier fix to add support for --cflags and --ldflags options
12503 that include quotes so that it works whether make uses cmd or
12506 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12508 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12509 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12511 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12512 a string. Handle both cases.
12513 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12514 (Fdbus_register_method): Use Qinvalid_function.
12516 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12518 * makefile.w32-in: Update dependencies.
12519 (LISP_H): Add inttypes.h and stdin.h.
12520 (PROCESS_H): Add unistd.h.
12522 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12524 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12525 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12527 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12529 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12531 * term.c (vfatal): Remove stray call to va_end.
12532 It's not needed and the C Standard doesn't allow it here anyway.
12534 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12535 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12537 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12540 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12542 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12544 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12546 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12548 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12550 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12551 * charset.c (Fdefine_charset_internal): Don't initialize
12552 charset.code_space[15]. The value was garbage, on hosts with
12553 32-bit int (Bug#8600).
12555 * lread.c (read_integer): Be more consistent with string-to-number.
12556 Use string_to_number to do the actual conversion; this avoids
12557 rounding errors and fixes some other screwups. Without this fix,
12558 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12559 (digit_to_number): Move earlier, for benefit of read_integer.
12560 Return -1 if the digit is out of range for the base, -2 if it is
12561 not a digit in any supported base. (Bug#8602)
12563 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12565 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12566 to match comment at start of function. This also removes a
12567 GCC warning about overflow in a 32+64-bit port.
12569 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12571 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12572 Reported by Stefan Monnier in
12573 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12574 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12575 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12577 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12578 (EMACS_UINTPTR): Likewise, with uintptr_t.
12580 * lisp.h: Prefer 64-bit EMACS_INT if available.
12581 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12582 on 32-bit hosts that have 64-bit int, so that they can access
12584 However, temporarily disable this change unless the temporary
12585 symbol WIDE_EMACS_INT is defined.
12587 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12589 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12590 This removes an assumption that EMACS_INT and long are the same
12591 width as pointers. The assumption is true for Emacs porting targets
12592 now, but we want to make other targets possible.
12593 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12594 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12595 In the rest of the code, change types of integers that hold casted
12596 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12597 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12598 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12599 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12600 No need to cast type when ORing.
12601 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12602 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12603 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12604 assume EMACS_INT is the same width as char *.
12605 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12606 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12607 Remove no-longer-needed casts.
12608 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12609 (xg_tool_bar_help_callback, xg_make_tool_item):
12610 Use EMACS_INTPTR to hold an integer
12611 that will be cast to void *; this can avoid a GCC warning
12612 if EMACS_INT is not the same width as void *.
12613 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12614 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12615 (current_message_1, set_message_1):
12616 Use a local to convert to proper width without a cast.
12617 * xmenu.c (dialog_selection_callback): Likewise.
12619 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12620 Also, don't assume VALBITS / RAND_BITS is less than 5,
12621 and don't rely on undefined behavior when shifting a 1 left into
12623 * lisp.h (get_random): Change signature to match.
12625 * lread.c (hash_string): Use size_t, not int, for hash computation.
12626 Normally we prefer signed values; but hashing is special, because
12627 it's better to use unsigned division on hash table sizes so that
12628 the remainder is nonnegative. Also, size_t is the natural width
12629 for hashing into memory. The previous code used 'int', which doesn't
12630 retain enough info to hash well into very large tables.
12631 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12633 * dbusbind.c: Don't possibly lose pointer info when converting.
12634 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12635 Use XPNTR rather than XHASH, so that the high-order bits of
12636 the pointer aren't lost when converting through void *.
12638 * eval.c (Fautoload): Don't double-shift a pointer.
12640 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

12723 * process.c: Include lisp.h before w32.h, not after.
12724 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12725 instead of gnutls_record_check_pending.

12729 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12731 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

12777 rather than `XVECTOR (FOO)->size'.
12779 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12780 inttypes.h, as a gnulib replacement is used if it not available in
12783 2011-04-21 Eli Zaretskii <eliz@gnu.org>

12795 charbuf for the composition carryover bytes.
12797 2011-04-21 Eli Zaretskii <eliz@gnu.org>

12802 %llo or %llx format is passed. (Bug#8545)
12804 * window.c (window_scroll_line_based): Use a marker instead of
12805 simple variables to record original value of point. (Bug#7952)
12807 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12808 produced by %s or %c overflows available buffer space. (Bug#8545)
12810 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12812 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12813 (SIZE_MAX): Move defn after all includes, as they might #define it.
12815 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12817 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12819 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12821 * keyboard.c (Qdelayed_warnings_hook): Define.
12822 (command_loop_1): Run `delayed-warnings-hook'
12823 if Vdelayed_warnings_list is non-nil.
12824 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12825 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12827 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12829 * doprnt.c (doprnt): Don't return value smaller than the buffer
12830 size if the message was truncated. (Bug#8545).
12832 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12834 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12835 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12837 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12839 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12841 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12843 * makefile.w32-in: Update dependencies.
12845 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12847 Improve `doprnt' and its usage. (Bug#8545)
12848 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12849 `format_end'. Remove support for %l as a conversion specifier.
12850 Don't use xrealloc. Improve diagnostics when the %l size modifier
12851 is used. Update the commentary.
12853 * eval.c (verror): Simplify calculation of size_t.
12855 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12858 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12860 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12863 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12865 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12866 This makes this file independent of the recent pseudovector change.
12868 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12870 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12872 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12873 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12874 Remove unused local.
12875 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12877 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12878 GCC 4.6.0 optimizes based on type-based alias analysis.
12879 For example, if b is of type struct buffer * and v of type struct
12880 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12881 != &v->size, and therefore "v->size = 1; b->size = 2; return
12882 v->size;" must therefore return 1. This assumption is incorrect
12883 for Emacs, since it type-puns struct Lisp_Vector * with many other
12884 types. To fix this problem, this patch adds a new type struct
12885 vectorlike_header that documents the constraints on layout of vectors
12886 and pseudovectors, and helps optimizing compilers not get fooled
12887 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12888 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12889 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12891 (XSETPVECTYPE): Rewrite in terms of new macro.
12892 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12893 This is a bit clearer, and further avoids the possibility of
12894 undesirable aliasing.
12895 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12896 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12897 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12898 since Lisp_Subr is a special case (no "next" field).
12899 (ASIZE): Now uses header.size rather than size.
12900 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12901 to avoid the hassle of writing XVECTOR (foo)->header.size.
12902 (struct vectorlike_header): New type.
12903 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12904 object, to help avoid aliasing.
12905 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12906 (SUBRP): Likewise, since Lisp_Subr is a special case.
12907 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12908 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12909 (struct Lisp_Hash_Table): Combine first two members into a single
12910 struct vectorlike_header member. All uses of "size" and "next" members
12911 changed to be "header.size" and "header.next".
12912 * buffer.h (struct buffer): Likewise.
12913 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12914 * frame.h (struct frame): Likewise.
12915 * process.h (struct Lisp_Process): Likewise.
12916 * termhooks.h (struct terminal): Likewise.
12917 * window.c (struct save_window_data, struct saved_window): Likewise.
12918 * window.h (struct window): Likewise.
12919 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12920 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12921 * buffer.c (init_buffer_once): Likewise.
12922 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12924 * process.c (Fformat_network_address): Use local var for size,
12927 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12929 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12930 * data.c (atof): Remove decl; no longer used or needed.
12931 (digit_to_number): Move to lread.c.
12932 (Fstring_to_number): Use new string_to_number function, to be
12933 consistent with how the Lisp reader treats infinities and NaNs.
12934 Do not assume that floating-point numbers represent EMACS_INT
12935 without losing information; this is not true on most 64-bit hosts.
12936 Avoid double-rounding errors, by insisting on integers when
12937 parsing non-base-10 numbers, as the documentation specifies.
12938 * lisp.h (string_to_number): New decl, replacing ...
12939 (isfloat_string): Remove.
12940 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12941 (read1): Do not accept +. and -. as integers; this
12942 appears to have been a coding error. Similarly, do not accept
12943 strings like +-1e0 as floating point numbers. Do not report
12944 overflow for integer overflows unless the base is not 10 which
12945 means we have no simple and reliable way to continue.
12946 Break out the floating-point parsing into a new
12947 function string_to_number, so that Fstring_to_number parses
12948 floating point numbers consistently with the Lisp reader.
12949 (digit_to_number): Move here from data.c. Make it static inline.
12950 (E_CHAR, EXP_INT): Remove, replacing with ...
12951 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12952 (string_to_number): New function, replacing isfloat_string.
12953 This function checks for valid syntax and produces the resulting
12954 Lisp float number too. Rework it so that string-to-number
12955 no longer mishandles examples like "1.0e+". Use strtoumax,
12956 so that overflow for non-base-10 numbers is reported only when
12957 there's no portable and simple way to convert to floating point.
12959 * textprop.c (set_text_properties_1): Rewrite for clarity,
12960 and to avoid GCC warning about integer overflow.
12962 * intervals.h (struct interval): Use EMACS_INT for members
12963 where EMACS_UINT might cause problems. See
12964 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12965 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12966 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12968 (offset_intervals): Tell GCC not to worry about length overflow
12969 when negating a negative length.
12971 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12972 (overrun_check_free): Likewise.
12974 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12975 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12978 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12979 (gnutls_make_error): Rename local to avoid shadowing.
12980 (gnutls_emacs_global_deinit): ifdef out; not used.
12981 (Fgnutls_boot): Use const for pointer to readonly storage.
12982 Comment out unused local. Fix pointer signedness problems.
12984 * lread.c (openp): Don't stuff size_t into an 'int'.
12985 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12986 about possible signed overflow.
12988 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12989 (GDK_KEY_g): Don't define if already defined.
12990 (xg_prepare_tooltip): Avoid pointer signedness problem.
12991 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12993 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12994 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12996 * xfns.c (Fx_window_property): Simplify a bit,
12997 to make a bit faster and to avoid GCC 4.6.0 warning.
12998 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
13000 * fns.c (internal_equal): Don't assume size_t fits in int.
13002 * alloc.c (compact_small_strings): Tighten assertion a little.
13004 Replace pEd with more-general pI, and fix some printf arg casts.
13005 * lisp.h (pI): New macro, generalizing old pEd macro to other
13006 conversion specifiers. For example, use "...%"pI"d..." rather
13007 than "...%"pEd"...".
13008 (pEd): Remove. All uses replaced with similar uses of pI.
13009 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
13010 * alloc.c (check_pure_size): Don't overflow by converting size to int.
13011 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
13012 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
13013 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
13014 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
13015 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
13017 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
13018 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
13019 * print.c (safe_debug_print, print_object): Likewise.
13020 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
13022 Use pI instead of if-then-else-abort. Use %p to avoid casts,
13023 avoiding the 0 flag, which is not portable.
13024 * process.c (Fmake_network_process): Use pI to avoid cast.
13025 * region-cache.c (pp_cache): Likewise.
13026 * xdisp.c (decode_mode_spec): Likewise.
13027 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
13028 behavior on 64-bit hosts with printf arg.
13029 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
13030 (x_stop_queuing_selection_requests): Likewise.
13031 (x_get_window_property): Don't truncate byte count to an 'int'
13034 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
13035 here, since it parses constructs like leading '-' and spaces,
13036 which are not wanted; and it overflows with large numbers.
13037 Instead, simply match F[0-9]+, which is what is wanted anyway.
13039 * alloc.c: Remove unportable assumptions about struct layout.
13040 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
13041 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
13042 (allocate_vectorlike, make_pure_vector): Use the new macros,
13043 plus offsetof, to remove unportable assumptions about struct layout.
13044 These assumptions hold on all porting targets that I know of, but
13045 they are not guaranteed, they're easy to remove, and removing them
13046 makes further changes easier.
13048 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
13049 This doesn't fix a bug but makes the code clearer.
13050 (string_overrun_cookie): Now const. Use initializers that

13945 and to avoid potential problems with integer overflow.
13946 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13947 * casetab.c (set_identity, shuffle): Likewise.
13948 * editfns.c (Fformat): Likewise.
13949 * syntax.c (skip_chars): Likewise.
13951 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13952 This also lets GCC 4.6.0 generate slightly better loop code.
13954 * callint.c (Fcall_interactively): <, not <=, for optimization.
13955 (Fcall_interactively): Count the number of arguments produced,
13956 not the number of arguments given. This is simpler and lets GCC
13957 4.6.0 generate slightly better code.
13959 * ftfont.c: Distingish more carefully between FcChar8 and char.
13960 The previous code passed unsigned char * to a functions like
13961 strlen and xstrcasecmp that expect char *, which does not
13962 conform to the C standard.
13963 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13964 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13965 char * when the C standard requires it.
13967 * keyboard.c (read_char): Remove unused var.
13969 * eval.c: Port to Windows vsnprintf (Bug#8435).
13970 Include <limits.h>.
13971 (SIZE_MAX): Define if the headers do not.
13972 (verror): Do not give up if vsnprintf returns a negative count.
13973 Instead, grow the buffer. This ports to Windows vsnprintf, which
13974 does not conform to C99. Problem reported by Eli Zaretskii.
13975 Also, simplify the allocation scheme, by avoiding the need for
13976 calling realloc, and removing the ALLOCATED variable.
13978 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13980 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13981 But keep the doprint source code for now, as we might revamp it
13982 and use it again (Bug#8435).
13983 * lisp.h (doprnt): Remove.
13984 * Makefile.in (base_obj): Remove doprnt.o.
13985 * deps.mk (doprnt.o): Remove.
13987 error: Print 32- and 64-bit integers portably (Bug#8435).
13988 Without this change, on typical 64-bit hosts error ("...%d...", N)
13989 was used to print both 32- and 64-bit integers N, which relied on
13990 undefined behavior.
13991 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13992 * lisp.h (error, verror): Mark as printf-like functions.
13993 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13994 Report overflow in size calculations when allocating printf buffer.
13995 Do not truncate output string at its first null byte.
13996 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13997 Truncate the output at a character boundary, since vsnprintf does not
13999 * charset.c (check_iso_charset_parameter): Convert internal
14000 character to string before calling 'error', since %c now has the
14002 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
14003 overflow when computing char to be passed to 'error'. Do not
14004 pass Lisp_Object to 'error'; pass the integer instead.
14005 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
14006 formatted with plain %d.
14008 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
14010 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
14012 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
14014 * xterm.c (x_catch_errors): Remove duplicate declaration.
14016 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
14018 * xdisp.c, lisp.h (message_nolog): Remove; unused.
14020 2011-04-10 Jim Meyering <meyering@redhat.com>
14022 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
14023 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
14024 return ssize_t not "int", and use size_t as the buffer length.
14025 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
14026 * gnutls.h: Update declarations.
14027 * process.c (read_process_output): Use ssize_t, to match.
14028 (send_process): Likewise.
14030 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14032 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
14034 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14036 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
14037 Use unsigned char, to match FcChar8 type definition.
14039 * xterm.c (handle_one_xevent):
14040 * xmenu.c (create_and_show_popup_menu):
14041 * xselect.c (x_decline_selection_request)
14042 (x_reply_selection_request): Avoid type-punned deref of X events.
14044 2011-04-09 Eli Zaretskii <eliz@gnu.org>
14046 Fix some uses of `int' instead of EMACS_INT.
14047 * search.c (string_match_1, fast_string_match)
14048 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
14049 (scan_buffer, find_next_newline_no_quit)
14050 (find_before_next_newline, search_command, Freplace_match)
14051 (Fmatch_data): Make some `int' variables be EMACS_INT.
14053 * xdisp.c (display_count_lines): 3rd argument and return value now
14054 EMACS_INT. All callers changed.
14055 (pint2hrstr): Last argument is now EMACS_INT.
14057 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
14058 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
14059 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
14060 (decode_coding_utf_16, decode_coding_emacs_mule)
14061 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
14062 (decode_coding_ccl, decode_coding_charset)
14063 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
14064 (decode_coding_iso_2022, decode_coding_emacs_mule)
14065 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
14066 <char_offset, last_offset>: Declare EMACS_INT.
14067 (encode_coding_utf_8, encode_coding_utf_16)
14068 (encode_coding_emacs_mule, encode_invocation_designation)
14069 (encode_designation_at_bol, encode_coding_iso_2022)
14070 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
14071 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
14073 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
14074 (encode_invocation_designation): Last argument P_NCHARS is now
14076 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
14077 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
14079 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
14082 * ccl.c (Fccl_execute_on_string): Declare some variables
14085 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
14087 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
14089 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
14091 * process.c (Fformat_network_address): Doc fix.
14093 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
14095 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
14097 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
14099 * keyboard.c (read_char): Call Lisp function help-form-show,
14100 instead of using internal_with_output_to_temp_buffer.
14101 (Qhelp_form_show): New var.
14102 (syms_of_keyboard): Use DEFSYM macro.
14104 * print.c (internal_with_output_to_temp_buffer): Function deleted.
14106 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
14108 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
14110 * process.c (Flist_processes): Remove to Lisp.
14111 (list_processes_1): Delete.
14113 2011-04-06 Eli Zaretskii <eliz@gnu.org>
14115 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
14117 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
14119 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
14121 Fix more problems found by GCC 4.6.0's static checks.
14123 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
14125 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
14127 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
14129 * xdisp.c (vmessage): Mark as a printf-like function.
14131 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
14133 * sound.c (sound_warning): Don't crash if arg contains a printf format.
14135 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
14136 printf-like functions.
14137 (tiff_load): Add casts to remove these marks before passing them
14138 to system-supplied API.
14140 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14142 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14143 This avoids several warnings with gcc -Wstrict-overflow.
14144 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14145 directly, rather than having caller test rule sign. This avoids
14146 some unnecessary tests.
14147 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14148 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14149 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14151 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14152 (xfont_open): Avoid unnecessary tests.
14154 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14156 * composite.h, composite.c (composition_gstring_put_cache):
14157 Use EMACS_INT, not int, for length.
14159 * composite.h (COMPOSITION_DECODE_REFS): New macro,
14160 breaking out part of COMPOSITION_DECODE_RULE.
14161 (COMPOSITION_DECODE_RULE): Use it.
14162 * composite.c (get_composition_id): Remove unused local vars,
14163 by using the new macro.
14165 * textprop.c (set_text_properties_1): Change while to do-while,
14166 since the condition is always true at first.
14168 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14169 (interval_deletion_adjustment): Return unsigned value.
14172 * process.c (list_processes_1, create_pty, read_process_output):
14173 (exec_sentinel): Remove vars that were set but not used.
14174 (create_pty): Remove unnecessary "volatile"s.
14175 (Fnetwork_interface_info): Avoid possibility of int overflow.

14177 (read_process_output): Simplify nbytes computation if buffered.
14179 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
14181 * syntax.c (scan_words): Remove var that was set but not used.
14182 (update_syntax_table): Use unsigned instead of int.
14184 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
14185 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
14186 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
14188 * print.c (print_error_message): Avoid int overflow.
14190 * font.c (font_list_entities): Redo for clarity,
14191 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14193 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14194 (font_score): Avoid potential overflow in diff calculation.
14196 * fns.c (substring_both): Remove var that is set but not used.
14197 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14199 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14201 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14202 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14203 can always succeed if overflow has undefined behavior.
14205 * search.c (boyer_moore, wordify): Remove vars set but not used.
14206 (wordify): Omit three unnecessary tests.
14208 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
14209 All callers changed. This avoids the need for an unused var.
14211 * casefiddle.c (casify_region): Remove var that is set but not used.
14213 * dired.c (file_name_completion): Remove var that is set but not used.
14215 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
14217 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
14218 (Finsert_file_contents): Remove unnecessary code checking fd.
14220 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14221 Check for integer overflow on size calculations.
14223 * buffer.c (Fprevious_overlay_change): Remove var that is set
14226 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14227 Remove vars that are set but not used.
14228 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
14229 (timer_check_2): Mark vars as initialized.
14231 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
14233 * image.c (lookup_image): Remove var that is set but not used.
14234 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
14236 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14237 that are set but not used.
14239 * xfns.c (make_invisible_cursor): Don't return garbage
14240 if XCreateBitmapFromData fails (Bug#8410).
14242 * xselect.c (x_get_local_selection, x_handle_property_notify):
14243 Remove vars that are set but not used.
14245 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
14246 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
14248 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
14249 Remove var that is set but not used.
14250 (scroll_bar_windows_size): Now size_t, not int.
14251 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
14252 Check for overflow.
14254 * xfaces.c (realize_named_face): Remove vars that are set but not used.
14255 (map_tty_color) [!defined MSDOS]: Likewise.
14257 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14259 * coding.c: Remove vars that are set but not used.
14260 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14261 All callers changed.
14262 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
14263 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
14264 (decode_coding_charset): Remove vars that are set but not used.
14266 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
14267 that is set but not used.
14269 * print.c (print_object): Remove var that is set but not used.
14271 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14272 The gnulib version avoids calling malloc in the usual case,
14273 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14274 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14275 * filelock.c (current_lock_owner): Likewise.
14276 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14277 * sysdep.c: Include allocator.h, careadlinkat.h.
14278 (emacs_no_realloc_allocator): New static constant.
14279 (emacs_readlink): New function.
14280 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14281 ../lib/careadlinkat.h.
14283 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14285 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14286 first non-nil return value).
14288 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
14290 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
14291 if not defined (Bug#8403).
14293 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14295 * xdisp.c (display_count_lines): Remove parameter `start',
14296 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14297 (get_char_face_and_encoding): Remove parameter `multibyte_p',
14298 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
14299 (fill_stretch_glyph_string): Remove parameters `row' and `area',
14300 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
14301 and thereabouts. All callers changed.
14302 (get_per_char_metric): Remove parameter `f', unused since
14303 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
14305 2011-04-02 Jim Meyering <meyering@redhat.com>
14307 do not dereference NULL upon failed strdup
14308 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
14309 (ns_get_family): Likewise.
14311 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14313 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
14315 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
14317 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
14320 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
14322 Add lexical binding.
14324 * window.c (Ftemp_output_buffer_show): New fun.
14325 (Fsave_window_excursion):
14326 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
14328 * lread.c (lisp_file_lexically_bound_p): New function.
14329 (Fload): Bind Qlexical_binding.
14330 (readevalloop): Remove `evalfun' arg.
14331 Bind Qinternal_interpreter_environment.
14332 (Feval_buffer): Bind Qlexical_binding.
14333 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
14335 (syms_of_lread): Declare `lexical-binding'.
14337 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
14339 * keyboard.c (eval_dyn): New fun.
14340 (menu_item_eval_property): Use it.
14342 * image.c (parse_image_spec): Use Ffunctionp.
14344 * fns.c (concat, mapcar1): Accept byte-code-functions.
14346 * eval.c (Fsetq): Handle lexical vars.
14347 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
14348 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
14349 (FletX, Flet): Obey lexical binding.
14350 (Fcommandp): Handle closures.
14351 (Feval): New `lexical' arg.
14352 (eval_sub): New function extracted from Feval. Use it almost
14353 everywhere where Feval was used. Look up vars in lexical env.
14355 (Ffunctionp): Move from subr.el.
14356 (Ffuncall): Handle closures.
14357 (apply_lambda): Remove `eval_flags'.
14358 (funcall_lambda): Handle closures and new byte-code-functions.
14359 (Fspecial_variable_p): New function.
14360 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14361 but without exporting it to Lisp.
14363 * doc.c (Fdocumentation, store_function_docstring):
14364 * data.c (Finteractive_form): Handle closures.
14366 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14369 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14371 (exec_byte_code): New function extracted from Fbyte_code to handle new
14372 calling convention for byte-code-functions. Add new byte-codes.
14374 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14376 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14378 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14380 * xdisp.c (redisplay_internal): Fix prototype.
14382 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14384 * xdisp.c (SCROLL_LIMIT): New macro.
14385 (try_scrolling): Use it when setting scroll_limit.
14386 Limit scrolling to 100 screen lines.
14387 (redisplay_window): Even when falling back on "recentering",
14388 position point in the window according to scroll-conservatively,
14389 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14391 (try_scrolling): When point is above the window, allow searching
14392 as far as scroll_max, or one screenful, to compute vertical
14393 distance from PT to the scroll margin position. This prevents
14394 try_scrolling from unnecessarily failing when
14395 scroll-conservatively is set to a value slightly larger than the
14396 window height. Clean up the case of PT below the margin at bottom
14397 of window: scroll_max can no longer be INT_MAX. When aggressive
14398 scrolling is in use, don't let point enter the opposite scroll
14399 margin as result of the scroll.
14400 (syms_of_xdisp) <scroll-conservatively>: Document the
14401 threshold of 100 lines for never-recentering scrolling.
14403 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14405 * dispextern.h (move_it_by_lines):
14406 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
14407 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
14408 (message_log_check_duplicate): Remove parameters `prev_bol' and
14409 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14410 (redisplay_internal): Remove parameter `preserve_echo_area',
14411 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14413 * indent.c (Fvertical_motion):
14414 * window.c (window_scroll_pixel_based, Frecenter):
14415 Don't pass `need_y_p' to `move_it_by_lines'.
14417 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14419 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14420 steal a few bits to be more compact.
14421 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14422 Remove unneeded casts.
14424 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14426 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14428 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14429 binding" message (bug#7967).
14431 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14433 Fix more problems found by GCC 4.6.0's static checks.
14435 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14436 Remove unused local var.
14438 * editfns.c (Fmessage_box): Remove unused local var.
14440 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14441 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14442 Omit unused local vars.
14443 * window.c (shrink_windows): Omit unused local var.
14444 * menu.c (digest_single_submenu): Omit unused local var.
14445 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14446 Omit unused local var.
14448 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14449 Don't assume string length fits in int.
14450 (keyremap_step, read_key_sequence): Use size_t for sizes.
14451 (read_key_sequence): Don't check last_real_key_start redundantly.
14453 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14454 instead of alloca (Bug#8344).
14456 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14457 (Fbacktrace_frame): Don't assume nframes fits in int.
14459 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14461 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14464 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14466 * cm.c (calccost): Turn while-do into do-while, for clarity.
14468 * keyboard.c (syms_of_keyboard): Use the same style as later
14469 in this function when indexing through an array. This also
14470 works around GCC bug 48267.
14472 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14474 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

14477 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14479 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14480 This avoids undefined behavior on integer overflow, and is a bit
14481 more convenient anyway since it is compared to a size_t variable.
14483 Variadic C functions now count arguments with size_t, not int.
14484 This avoids an unnecessary limitation on 64-bit machines, which
14485 caused (substring ...) to crash on large vectors (Bug#8344).
14486 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14487 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

14494 (funcall_lambda, mark_backtrace): Likewise.
14495 * fns.c (concat): Likewise.
14496 * frame.c (x_set_frame_parameters): Likewise.
14497 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14498 0 if not found, not -1. All callers changed.
14500 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14501 (stack_copy_size): Now size_t, not int.
14502 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

14507 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14508 All callers changed.
14510 * lisp.h (multibyte_char_to_unibyte):
14511 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14512 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14513 * character.h (CHAR_TO_BYTE8):
14514 * cmds.c (internal_self_insert):
14515 * editfns.c (general_insert_function):
14516 * keymap.c (push_key_description):
14517 * search.c (Freplace_match):
14518 * xdisp.c (message_dolog, set_message_1): All callers changed.
14520 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14522 * keyboard.c (safe_run_hook_funcall): New function.
14523 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14524 don't set the hook to nil, but remove the offending function instead.
14525 (Qcommand_hook_internal): Remove, unused.
14526 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14527 Vcommand_hook_internal.
14529 * eval.c (enum run_hooks_condition): Remove.
14530 (funcall_nil, funcall_not): New functions.
14531 (run_hook_with_args): Call each function through a `funcall' argument.
14532 Remove `cond' argument, now redundant.
14533 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14534 (Frun_hook_with_args_until_failure): Adjust accordingly.
14535 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

14539 * dispextern.h (string_buffer_position): Remove declaration.
14541 * print.c (strout): Remove parameter `multibyte', unused since
14542 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14544 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14545 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14546 All callers changed.
14548 * w32.c (_wsa_errlist): Use braces for struct initializers.
14550 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14551 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14552 All callers changed.
14553 (string_buffer_position): Likewise. Also, make static (it's never
14554 used outside xdisp.c).

14558 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14559 All callers changed.
14561 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14563 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

14574 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14576 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14578 * nsmenu.m (runDialogAt): Remove argument to timer_check.
14580 2011-03-27 Glenn Morris <rgm@gnu.org>
14582 * syssignal.h: Replace RETSIGTYPE with void.
14583 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:

14592 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14594 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14596 * w32.c (read_unc_volume): Use parameter `henum', instead of
14597 global variable `wget_enum_handle'.
14599 * keymap.c (describe_vector): Remove parameters `indices' and
14600 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14615 * gtkutil.c (xg_maybe_add_timer):
14616 * keyboard.c (readable_events):
14617 * process.c (wait_reading_process_output):
14618 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14620 * insdel.c (adjust_markers_gap_motion):
14621 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

14695 2011-03-23 Julien Danjou <julien@danjou.info>
14697 * term.c (Fsuspend_tty, Fresume_tty):
14698 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14699 * window.c (temp_output_buffer_show):
14700 * insdel.c (signal_before_change):
14701 * frame.c (Fhandle_switch_frame):

14703 * emacs.c (Fkill_emacs):
14704 * editfns.c (save_excursion_restore):
14705 * cmds.c (internal_self_insert):
14706 * callint.c (Fcall_interactively):
14707 * buffer.c (Fkill_all_local_variables):
14708 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14710 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14711 unconditionally since it does the check itself.
14713 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14715 Fix more problems found by GCC 4.5.2's static checks.
14717 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14718 the first time through the loop, since we know p0 < p1 then.
14719 This also avoids a gcc -Wstrict-overflow warning.
14721 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14722 leading to a memory leak, possible in functions like
14723 load_charset_map_from_file that can allocate an unbounded number
14724 of objects (Bug#8318).
14726 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14727 that could (at least in theory) be that large.
14729 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14730 This is less likely to overflow, and avoids undefined behavior if
14731 overflow does occur. All callers changed. Use strtoul to scan
14732 for the unsigned long integer.
14733 (pint2hrstr): Simplify and tune code slightly.
14734 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14742 This also avoids a warning with gcc -Wstrict-overflow.
14744 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14747 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14749 * process.c (Fmake_network_process): Use socklen_t, not int,
14750 where POSIX says socklen_t is required in portable programs.
14751 This fixes a porting bug on hosts like 64-bit HP-UX, where
14752 socklen_t is wider than int (Bug#8277).
14753 (Fmake_network_process, server_accept_connection):
14754 (wait_reading_process_output, read_process_output):
14757 * process.c: Rename or move locals to avoid shadowing.
14758 (list_processes_1, Fmake_network_process):
14759 (read_process_output_error_handler, exec_sentinel_error_handler):
14760 Rename or move locals.
14761 (Fmake_network_process): Define label "retry_connect" only if needed.
14762 (Fnetwork_interface_info): Fix pointer signedness.
14763 (process_send_signal): Add cast to avoid pointer signedness problem.
14764 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14765 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14767 Make tparam.h and terminfo.c consistent.
14768 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14769 Include tparam.h instead, since it declares them.
14770 * cm.h (PC): Remove extern decl; tparam.h now does this.
14771 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14772 * terminfo.c: Include tparam.h, to check interfaces.
14773 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14774 (tparam): Adjust signature to match interface in tparam.h;
14775 this removes some undefined behavior. Check that outstring and len
14776 are zero, which they always are with Emacs.
14777 * tparam.h (PC, BC, UP): New extern decls.
14779 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14780 (xftfont_open): Rename locals to avoid shadowing.
14782 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14783 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14784 (OTF_TAG_SYM): Omit macro if not needed.
14785 (ftfont_list): Remove unused local.
14786 (get_adstyle_property, ftfont_pattern_entity):
14787 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
14788 Rename locals to avoid shadowing.
14790 * xfont.c (xfont_list_family): Mark var as initialized.
14792 * xml.c (make_dom): Now static.
14794 * composite.c (composition_compute_stop_pos): Rename local to
14796 (composition_reseat_it): Remove unused locals.
14797 (find_automatic_composition, composition_adjust_point): Likewise.
14798 (composition_update_it): Mark var as initialized.
14799 (find_automatic_composition): Mark vars as initialized,
14800 with a FIXME (Bug#8290).
14802 character.h: Rename locals to avoid shadowing.
14803 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14804 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14805 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14806 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14807 to avoid shadowing.
14809 * textprop.c (property_change_between_p): Remove; unused.
14811 * intervals.c (interval_start_pos): Now static.
14813 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
14815 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
14816 Rename locals to avoid shadowing.
14818 * sound.c (wav_play, au_play, Fplay_sound_internal):
14819 Fix pointer signedness.
14820 (alsa_choose_format): Remove unused local var.
14821 (wav_play): Initialize a variable to 0, to prevent undefined
14822 behavior (Bug#8278).
14824 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14826 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14828 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14829 clobbering (Bug#8298).
14830 * sysdep.c (sys_subshell): Likewise.
14831 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14833 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14834 This should get cleaned up, so that child_setup has the

15006 Use functions, not macros, for up- and down-casing (Bug#8254).
15007 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15008 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
15009 to use the following functions instead of these macros.
15010 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
15011 EMACS_INT, since callers assume the returned value fits in int.
15012 (upcase1): Likewise, for UPCASE_TABLE.
15013 (uppercasep, lowercasep, upcase): New static inline functions.
15014 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

15024 (regex_compile, re_match_2_internal): Mark locals as initialized.
15025 (RETALLOC_IF): Define only if needed.
15026 (WORDCHAR_P): Likewise. This one is never needed, but is used
15027 only in a comment talking about a compiler bug, so put inside
15028 the #if 0 of that comment.
15029 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
15030 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

15056 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
15057 New macros, so that the caller can use some names other than
15058 gcpro1, gcpro2, etc.
15059 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15061 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15062 argument, for consistency with GCPRO2_VAR, etc: it is now the
15063 prefix of the variable, not the variable itself. All uses
15065 * dired.c (directory_files_internal, file_name_completion):
15066 Rename locals to avoid shadowing.
15068 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15069 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15070 dired.c's scmp function, had undefined behavior.
15071 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15072 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15073 * buffer.h: ... to here, because these macros use current_buffer,
15074 and the new implementation with inline functions needs to have
15075 current_buffer in scope now, rather than later when the macros
15077 (downcase, upcase1): New static inline functions.
15078 (DOWNCASE, UPCASE1): Reimplement using these functions.
15079 This avoids undefined behavior in expressions like
15080 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15081 from race conditions in accessing the global variables
15082 case_temp1 and case_temp2.
15083 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15084 * lisp.h (case_temp1, case_temp2): Remove their decls.
15085 * character.h (ASCII_CHAR_P): Move from here ...
15086 * lisp.h: ... to here, so that the inline functions mentioned
15087 above can use them.
15089 * dired.c (directory_files_internal_unwind): Now static.
15091 * fileio.c (file_name_as_directory, directory_file_name):

15094 (file_name_as_directory): Use const pointers when appropriate.
15095 (Fexpand_file_name): Likewise. In particular, newdir might
15096 point at constant storage, so make it a const pointer.
15097 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
15098 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15100 (Fset_file_times, Finsert_file_contents, auto_save_error):

15105 to avoid shadowing.
15107 * marker.c (bytepos_to_charpos): Remove; unused.
15109 * lisp.h (verify_bytepos, count_markers): New decls,
15110 so that gcc does not warn that these functions aren't declared.
15112 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
15113 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
15114 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
15115 (copy_text): Remove unused local var.
15117 * filelock.c (within_one_second): Now static.
15118 (lock_file_1): Rename local to avoid shadowing.
15120 * buffer.c (fix_overlays_before): Mark locals as initialized.
15121 (fix_start_end_in_overlays): Likewise. This function should be
15122 simplified by using pointers-to-pointers, but that's a different
15124 (switch_to_buffer_1): Now static.
15125 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15126 (report_overlay_modification): Rename locals to avoid shadowing.
15128 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
15129 Fix pointer signedness issue.
15130 (sys_subshell): Mark local as volatile if checking for lint,
15131 to suppress a gcc -Wclobbered warning that does not seem to be right.
15132 (MAXPATHLEN): Define only if needed.
15134 * process.c (serial_open, serial_configure): Move decls from here ...
15135 * systty.h: ... to here, so that they can be checked.
15137 * fns.c (get_random, seed_random): Move extern decls from here ...
15138 * lisp.h: ... to here, so that they can be checked.
15140 * sysdep.c (reset_io): Now static.
15141 (wait_for_termination_signal): Remove; unused.
15143 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

15146 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
15147 (DENSE_TABLE_SIZE): Remove; unused.
15148 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
15149 (describe_map_tree):
15150 Rename locals to avoid shadowing.
15152 * keyboard.c: Declare functions static if they are not used elsewhere.
