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

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

689 installation tree, as appropriate.
691 * callproc.c (init_callproc_1): Call decode_env_path instead of
692 doing its equivalent by hand.

725 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
726 Remove unnecessary pointer casts.
727 * alloc.c (record_xmalloc): New function.
728 * lisp.h (record_xmalloc): New decl.
729 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
730 more like a function. This is because the pointer cast is not
731 needed. All uses changed.
732 * print.c (print_string, print_error_message): Avoid length recalc.
734 Improve fix for macroexp crash with debugging (Bug#12118).
735 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
736 ARRAY_MARK_FLAG when checking subscripts, because ASET is
737 not supposed to be invoked from the garbage collector.
738 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
739 (gc_aset): New function, which is like ASET but can be
740 used in the garbage collector.

756 headers (most versions of MinGW w32api don't).
757 (get_security_info, create_symbolic_link)
758 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
760 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

771 handle, not by name. Produce S_IFLNK bit for symlinks, when
773 (stat, lstat): New functions, call 'stat_worker'.
774 (symlink, readlink, careadlinkat): Rewritten to create and resolve
775 symlinks when the underlying filesystem supports them.
777 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
779 Fix macroexp crash on Windows with debugging (Bug#12118).
780 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
781 checking subscripts; problem introduced with the recent
782 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
783 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
784 since it's used in non-static inline functions now.
786 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
787 Don't assume buffer size fits in 'int'. Remove unused local.
789 Use C99-style 'extern inline' if available.

807 * composite.c (COMPOSITE_INLINE):
808 * dispnew.c (DISPEXTERN_INLINE):
809 * sysdep.c (SYSTIME_INLINE):

811 are compiled into code.
812 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
813 (INLINE_HEADER_END): New macros.
814 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

836 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
838 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
839 This how ASET and AREF are supposed to work, and makes
840 it easier to think about future improvements. See
841 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
842 * charset.h (set_charset_attr): New function.

1224 (w32_kbd_patch_key, key_event): Use the codepage returned by
1225 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

1334 the fix for 12036 would have avoided some of the problems noted in
1335 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
1336 would have been more obvious.

1346 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1347 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1348 not be usable in #if. This simplifies things.
1350 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1352 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

1357 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1358 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1359 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1360 Adjust to changes in lisp.h and emacs.c, by using

1363 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

1365 instead of gdb_valbits.
1366 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
1367 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
1368 instead of gdb_array_mark_flag.
1369 (xboolvector): Get size from $->size, not $->header.size.
1370 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1371 (xreload, hook-run, hookpost-run): Remove.
1372 * emacs.c: Include <verify.h>.
1373 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1374 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):

2265 (menu_separator_name_p):

2267 Prefer memcmp to strncmp when either will do.
2268 * nsterm.m: Include <ftoastr.h>.
2270 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
2271 Prefer snprintf to strncpy.
2272 * nsterm.m (ns_term_init):
2273 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2274 * nsterm.m (ns_term_init):
2275 Avoid the need for strncpy, by using build_string or
2276 make_unibyte_string directly. Use dtoastr, not snprintf.
2277 * process.c (Fmake_network_process): Diagnose service names that
2278 are too long, rather than silently truncating them or creating
2279 non-null-terminated names.

2309 Optimize pure C strings initialization.
2310 * lisp.h (make_pure_string): Fix prototype.
2311 (build_pure_c_string): New function, defined as static inline. This
2312 provides a better opportunity to optimize away calls to strlen when
2313 the function is called with compile-time constant argument.
2314 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2315 argument, adjust users accordingly. Use build_pure_c_string where
2317 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2318 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
2319 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
2321 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2323 Avoid calls to strlen in miscellaneous functions.
2324 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
2325 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.

2336 Adjust users accordingly.
2337 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2339 2012-07-10 Glenn Morris <rgm@gnu.org>

2346 * s/gnu.h (DATA_START): Move definitions to configure.
2348 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2349 We include usg5-4-common.h, which defines them both.
2351 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2352 O_RDONLY already includes it).
2354 Stop ns builds setting the EMACSLOADPATH environment variable.
2355 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2356 Now it does not set EMACSLOADPATH, just returns the load-path string.
2357 * nsterm.h: Update accordingly.
2358 * lread.c [HAVE_NS]: Include nsterm.h.
2359 (init_lread) [HAVE_NS]: Use ns_load_path.

2362 2012-07-09 Glenn Morris <rgm@gnu.org>
2364 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2365 since the included bsd-common.h does so.
2367 Stop ns builds setting the EMACSPATH environment variable.
2368 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2369 (ns_init_paths): Do not set EMACSPATH.
2370 * nsterm.h (ns_exec_path): Add it.
2371 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2374 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2376 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2378 * process.c (wait_reading_process_output): 'waitchannels' was unset
2379 when read_kbd || !NILP (wait_for_cell); fix this.
2381 Add GCC-style 'const' attribute to functions that can use it.
2382 * character.h (char_resolve_modifier_mask):
2383 * keyboard.h (make_ctrl_char):
2384 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

2393 Add decls with ATTRIBUTE_CONST.
2395 Minor improvements to make_formatted_string.
2396 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2397 where int is good enough, as vsprintf returns an int.
2398 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2400 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2402 Use make_formatted_string to avoid double length calculation.
2403 * lisp.h (make_formatted_string): New prototype.
2404 * alloc.c (make_formatted_string): New function.
2405 * buffer.c (Fgenerate_new_buffer_name): Use it.

2427 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2429 Move marker debugging code under MARKER_DEBUG.
2430 * marker.c (MARKER_DEBUG): Move marker debugging code under
2431 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2432 for bootstrap with --enable-checking (~3x slowdown reported
2433 by Juanma Barranquero <lekktu@gmail.com>).
2434 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2436 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2438 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2439 See <http://bugs.gnu.org/11825#29>.
2441 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2443 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2444 has no font, use the frame's font. (Bug#11813)
2445 (display_line): Add commentary about displaying truncation glyphs
2447 (produce_special_glyphs): Move here from term.c.
2449 * term.c (produce_special_glyphs): Move to xdisp.c.
2451 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2454 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2456 * xdisp.c (display_line): Avoid warning about implicit declaration
2459 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2461 * lisp.h: Remove empty conditional.
2463 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2465 * lread.c (load_path_check): Now static.
2467 Fix some minor --with-ns problems found by static checking.
2468 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2469 (x_set_font) [!HAVE_X_WINDOWS]:
2470 * image.c (xpm_load_image) [HAVE_NS]:
2471 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2472 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2473 Remove unused local.
2474 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2475 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2476 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2477 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2478 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2479 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2480 Fix pointer signedness problem.
2481 * xfaces.c (FRAME_X_FONT_TABLE):
2482 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2484 2012-07-07 Glenn Morris <rgm@gnu.org>
2486 * lread.c (load_path_check): New function, split from init_lread.
2487 (init_lread): Reorganize. Motivation:
2488 If EMACSLOADPATH is set, check/warn about that rather than the
2489 defaults, which we are not going to use. Hence we can remove
2490 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2491 Don't warn if site-lisp directories are missing.
2492 If not installed, start from a blank load-path, since
2493 PATH_LOADSEARCH refers to the eventual installation directories.
2495 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2497 Support truncation and continuation glyphs on GUI frames, when
2498 fringes are disabled. (Bug#11832)
2499 * xdisp.c (init_iterator): Get dimensions of truncation and
2500 continuation glyphs even if on GUI frames.
2501 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2502 or both, are absent.
2503 (start_display, move_it_in_display_line_to): Handle the case of a
2504 GUI frame without a fringe to display continuation or truncation
2506 (insert_left_trunc_glyphs): Support GUI frames: make sure
2507 truncation glyphs overwrite enough glyphs from the current line to
2508 have sufficient space in pixels.
2509 (display_line): Support truncation and continuation glyphs on GUI
2510 frames. If some spare pixels are left on the line after inserting
2511 the truncation glyphs, fill that space with a stretch glyph of a
2512 suitably computed width.
2514 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2515 produce_glyphs, to support GUI sessions.
2517 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2519 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2521 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2523 Do not require float-time's arg to fit in time_t (Bug#11825).
2524 This works better on hosts where time_t is unsigned, and where
2525 float-time is applied to the (negative) difference between two times.
2526 * editfns.c (decode_time_components): Last arg is now double *,
2527 not int *, and means to store all the result as a double, without
2528 worrying about whether the seconds part fits in time_t.
2529 All callers changed.
2530 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2531 All callers changed.
2532 (Ffloat_time): Do not fail merely because the specified time falls
2533 outside of time_t range.
2535 2012-07-07 Glenn Morris <rgm@gnu.org>
2537 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2552 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2553 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2554 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

2557 * xfont.c (compare_font_names): Redo to omit the need for casts.
2559 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2561 * xfns.c (Fx_change_window_property): Doc fix.
2562 * w32fns.c (Fx_change_window_property): Doc fix.
2564 * w32fns.c (Fx_window_property): Accept the same arguments as the
2565 X Windows version. Doc fix.
2566 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2568 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2569 Eli Zaretskii <eliz@gnu.org>
2571 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2572 Windows-specific code from nt/config.nt moved here.
2573 Obsolete settings removed.
2575 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2577 * process.c: Avoid unnecessary calls to gettime.
2578 (wait_reading_process_output): Don't get the time of day
2579 when gobbling data immediately and not waiting, as there's no need
2580 for it in that case. This removes a FIXME.
2582 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2584 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2585 is defined (Bug#11768).
2587 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2589 Fix marker debugging code.
2590 * marker.c (byte_char_debug_check): Do not perform the check
2591 if buffer is not multibyte.
2592 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2593 Call byte_char_debug_check with correct arguments.
2595 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2597 Compile marker debugging code only if ENABLE_CHECKING is defined.
2598 * marker.c (byte_char_debug_check, count_markers):
2599 Use only if ENABLE_CHECKING is defined.
2600 (byte_debug_flag): Remove.
2601 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2602 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2604 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2606 Avoid code repetition in marker-related functions.
2607 * marker.c (attach_marker): New function.
2608 (Fset_marker, set_marker_restricted, set_marker_both)
2609 (set_marker_restricted_both): Use it.
2610 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2611 Consistently rename charno to charpos.
2612 (marker_position): Add eassert.
2613 (marker_byte_position): Convert to eassert.

2632 * window.c (save_window_save): Likewise.
2634 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2636 Do not use Fdelete_overlay in delete_all_overlays
2637 to avoid redundant calls to unchain_overlay.
2638 * buffer.c (drop_overlay): New function.
2639 (delete_all_overlays, Fdelete_overlay): Use it.
2640 * minibuf.c (get_minibuffer): Fix comment.
2642 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2644 Port to OpenBSD 5.1 amd64.
2645 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2646 This is needed for OpenBSD, and should be harmless on all BSD systems.
2647 Also, include <sys/sysctl.h>, as it should be available on all
2648 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2649 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2650 use p_pid member, not kp_proc.pid.
2652 2012-07-06 Glenn Morris <rgm@gnu.org>
2654 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2656 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2658 More xmalloc and related cleanup.

2667 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2669 Omit needless casts involving void * pointers and allocation.
2670 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2671 as the former is more robust if P's type is changed.
2672 Prefer xzalloc to xmalloc + memset 0.
2673 Simplify malloc-or-realloc to realloc.
2674 Don't worry about xmalloc returning a null pointer.
2675 Prefer xstrdup to xmalloc + strcpy.
2676 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2678 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2679 alloca of a constant.
2681 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2683 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2684 hscroll is larger than the line width. Fixes long and futile
2685 looping inside extend_face_to_end_of_line (on a TTY) producing
2686 glyphs that are not needed and thrown away.
2688 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2690 * marker.c (set_marker_restricted_both): Simplify by using
2693 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

2716 * xdisp.c (window_hscroll_limited): New function.
2717 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2718 coordinates when window's hscroll is set to insanely large

2782 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2784 * fileio.c (time_error_value): Check the right error number.
2785 Problem reported by Troels Nielsen in
2786 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2788 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2790 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2791 This should be fixed in a better way; see Eli Zaretskii in
2792 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2793 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2795 * fileio.c (time_error_value): Rename from special_mtime.
2796 The old name's problems were noted by Eli Zaretskii in
2797 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2799 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2800 This variable's comment says Emacs needs at least one GDB-visible
2801 symbol of type enum pvec_type, to work around GDB problems.
2802 The symbol's value doesn't matter.
2804 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2805 that causes compilation to fail on pre-C99 compilers.
2807 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2809 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2810 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2812 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2814 * buffer.c (init_buffer_once): Fix initialization of
2815 headers for buffer_defaults and buffer_local_symbols.
2816 Reported by Juanma Barranquero <lekktu@gmail.com>.
2818 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2820 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2821 * lisp.h (enum pvec_type): Use fewer bits.
2822 (PSEUDOVECTOR_SIZE_BITS): New constant.
2823 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2824 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2825 change in pvec_type.
2826 (PSEUDOVECTOR_TYPEP): New macro.
2827 (TYPED_PSEUDOVECTORP): Use it.
2828 * fns.c (internal_equal): Adapt code to extract pvectype.
2829 * emacs.c (gdb_pvec_type): Update type.
2830 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2831 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2832 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2833 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2834 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2835 abusing vector->header.next.nbytes.
2836 (live_vector_p): Use PVEC_TYPE.
2837 (mark_object): Adapt code to extract pvectype. Use switch.
2839 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2841 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2842 Tighten new eassert a bit.
2844 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2846 Fix compilation with --enable-gcc-warnings and -O1
2848 * doprnt.c (doprnt): Change type of tem to int, initialize
2849 to avoid compiler warning. Add eassert.
2850 * search.c (simple_search): Initialize match_byte to avoid
2851 compiler warning. Add eassert.
2853 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2855 Avoid weird behavior with large horizontal scrolls.
2856 Without this change, for example, large hscroll values would
2857 mess up Emacs's display on Fedora 15 x86, presumably due to
2858 overflows in int calculations in the display code.
2859 Also, if buffers had long lines, Emacs would freeze.
2860 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2861 (set_window_hscroll): New function, containing the old guts of
2862 Fset_window_hscroll. Return the clipped value.
2863 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2864 This avoids the need to check against PTRDIFF_MAX.
2866 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2868 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2870 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2872 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2874 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2875 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2876 since GCC 4.4.6 issues a bogus warning for them.
2878 Fix bugs in file timestamp newness comparisons.
2879 * fileio.c (Ffile_newer_than_file_p):
2880 * lread.c (Fload): Use full timestamp resolution of files,
2881 not just the 1-second resolution, so that files that are only
2882 slightly newer still count as newer.
2883 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2884 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2886 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2888 * fileio.c: Improve handling of file time marker. (Bug#11852)
2889 (special_mtime): New function.
2890 (Finsert_file_contents, Fverify_visited_file_modtime):
2891 Use it to set special mtime values consistently.
2893 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2895 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2896 marker for non-existing file. (Bug#11852)
2898 2012-07-03 Glenn Morris <rgm@gnu.org>
2900 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2901 and did not make it into globals.h).
2903 2012-07-03 Tom Tromey <tromey@redhat.com>
2905 * window.c (Fset_window_margins, Fset_window_fringes)
2906 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2907 * textprop.c (Fprevious_property_change): No longer static.
2908 * syntax.c (Fsyntax_table_p): No longer static.
2909 * process.c (Fget_process, Fprocess_datagram_address): No longer

2925 * callproc.c (Fgetenv_internal): No longer static.
2927 * ccl.h: Remove EXFUNs.
2928 * buffer.h: Remove EXFUNs.
2929 * dispextern.h: Remove EXFUNs.
2930 * intervals.h: Remove EXFUNs.
2931 * fontset.h: Remove EXFUN.
2932 * font.h: Remove EXFUNs.
2933 * dosfns.c (system_process_attributes): Remove EXFUN.
2934 * keymap.h: Remove EXFUNs.

2936 * w32term.h: Remove EXFUNs.
2937 * window.h: Remove EXFUNs.
2938 * xsettings.h: Remove EXFUN.
2939 * xterm.h: Remove EXFUN.
2941 2012-07-03 Glenn Morris <rgm@gnu.org>
2943 * lisp.h (Frandom): Make it visible to C.
2944 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2945 buffer for invisible buffers. (Bug#1229)
2947 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2949 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2950 values which aren't power of 2.
2951 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
2952 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2955 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2957 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2959 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2961 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2963 * alloc.c (allocate_vector_block): Remove redundant
2964 calls to mallopt if DOUG_LEA_MALLOC is defined.
2965 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2966 avoid calls to mallopt if zero_vector is returned.
2968 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2970 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2971 is enabled, avoid dereferencing NULL current_sblock if
2974 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2976 Cleanup basic buffer management.
2977 * buffer.h (struct buffer): Change layout to use generic vector
2978 marking code. Fix some comments. Change type of 'clip_changed'
2979 to bitfield. Remove unused #ifndef old.
2980 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2981 (GET_OVERLAYS_AT): Fix indentation.
2982 (for_each_per_buffer_object_at): New macro.
2983 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2986 * alloc.c (allocate_buffer): Adjust to match new layout of
2987 struct buffer. Fix comment.
2988 (mark_overlay): New function.

2990 Lisp area of struct buffer.
2991 (mark_object): Use it. Adjust marking of misc objects
2992 and related comments.
2994 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2996 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2997 wrapper that is not needed because the wrapped code is a no-op (zero
2998 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2999 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
3001 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
3003 * alloc.c (mark_buffer): Simplify. Remove prototype.
3004 (mark_object): Add comment. Reorganize marking of vector-like
3005 objects. Use CHECK_LIVE for all vector-like objects except buffers
3006 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
3007 Avoid redundant calls to mark_vectorlike for bool vectors.
3009 2012-06-30 Glenn Morris <rgm@gnu.org>
3011 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
3013 * epaths.in (PATH_SITELOADSEARCH): New.
3014 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
3015 This is rather than relying on --enable-locallisppath elements
3016 having "site-lisp" in their names. (Bug#10208#25, 11658)
3018 2012-06-30 Eli Zaretskii <eliz@gnu.org>
3020 * w32proc.c (sys_select): Accept and ignore one more argument.
3022 * w32.c (emacs_gnutls_pull): Call select with one more argument.
3024 * sysselect.h [DOS_NT]: Don't include sys/select.h.
3025 (pselect) [!MS_DOS]: Redirect to sys_select.
3027 * sysdep.c: Don't include dos.h and dosfns.h.
3029 * process.c (sys_select):
3030 * msdos.c (sys_select): Accept one more argument and ignore it.
3032 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
3033 adapt data types and code to that.
3036 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
3037 which clashes with the gnulib function of the same name.
3039 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3041 * font.c (font_style_to_value, font_style_symbolic)
3042 (font_prop_validate_style): Add type checks for values in
3045 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3047 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3050 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3052 * xdisp.c (try_window_id): Undo last change.
3054 * w32.c (getwd): Adjust commentary about startup_dir.
3055 (init_environment): Always call sys_access, even in non-MSVC
3056 builds. Don't chdir to the directory of the Emacs executable.
3057 This undoes code from 1997 which was justified by the need to
3058 "avoid conflicts when removing and renaming directories". But its
3059 downside was that every relative file name was being interpreted
3060 relative to the directory of the Emacs executable, which can never
3061 be TRT. In particular, it broke sys_access when called with
3062 relative file names.
3063 (sys_access): Map GetLastError to errno.
3065 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3067 * window.h (struct window): Change type of 'fringes_outside_margins'

3071 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3074 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
3076 * gnutls.c (emacs_gnutls_handshake):
3077 Add QUIT to make the loop interruptible.
3079 2012-06-29 Glenn Morris <rgm@gnu.org>
3081 * charset.c (init_charset): Make lack of etc/charsets fatal.
3083 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3085 * editfns.c (region_limit): Fix type mismatch.
3087 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3089 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3090 undefined. Convert from xassert to eassert.
3091 * nsmenu.m: Convert from xassert to eassert.
3092 * nsterm.m: Likewise.
3094 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3096 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3098 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3100 Avoid integer overflow on scroll-left and scroll-right.
3101 * window.c (HSCROLL_MAX): New macro.
3102 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3103 overflow when requested scroll falls outside ptrdiff_t range.
3105 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3107 * window.h (struct window): Change type of 'hscroll',
3108 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3109 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3110 Adjust users accordingly.
3111 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3112 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3113 from EMACS_INT to ptrdiff_t.
3114 (make_window): Omit redundant initialization.
3116 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
3118 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
3120 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3122 * window.h (struct window): Change type of 'use_time' and
3123 'sequence_number' from Lisp_Object to int.
3124 * frame.c (make_frame): Adjust users accordingly.
3125 * print.c (print_object): Likewise.
3126 * window.c (select_window, Fwindow_use_time, make_parent_window)
3127 (make_window): Likewise.
3129 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3131 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
3132 enabled with --enable-checking=[all,glyphs] configure option.
3133 Fix GLYPH_DEBUG usage assuming that it may be undefined,
3134 adjust comments accordingly.

3185 avoid GCC warning about unused macro.
3187 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3189 * alloc.c (allocate_string): Omit intervals initialization.
3190 * alloc.c (make_uninit_multibyte_string): Initialize intervals
3191 as in make_pure_string and make_pure_c_string.
3193 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3195 * alloc.c (allocate_string): Fix last change.
3197 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

3255 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3257 Use sprintf return value instead of invoking strlen on result.
3258 In the old days this wasn't portable, since some sprintf
3259 implementations returned char *. But they died out years ago and
3260 Emacs already assumes sprintf returns int.
3261 Similarly for float_to_string.
3262 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
3263 * ccl.c (ccl_driver):
3264 * character.c (string_escape_byte8):

3269 * xfns.c (syms_of_xfns):
3270 Use sprintf or float_to_string result to avoid need to call strlen.
3271 * data.c (Fnumber_to_string):
3272 Use make_unibyte_string, since the string must be ASCII.
3273 * lisp.h, print.c (float_to_string): Now returns int length.
3274 * term.c (produce_glyphless_glyph):
3275 Use sprintf result rather than recomputing it.
3277 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3278 * Makefile.in (ALL_CFLAGS):
3279 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
3280 * gmalloc.c, regex.c: Include <config.h> unconditionally.
3282 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3284 * dispextern.h (xstrcasecmp): Define to library function
3285 strcasecmp if available.
3286 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

3301 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
3303 * gtkutil.c (get_utf8_string): Remove redundant assignment.
3304 sprintf already null-terminates its output.
3306 * xfns.c (x_window): Remove redundant cast.
3308 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3310 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
3311 `const char *' to `char *' to avoid compiler warning.
3313 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3315 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
3316 instead of truncating it to 63 (admittedly a generous limit).
3318 * process.c: Fix spelling and caps in comments.
3320 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
3322 * emacs.c (setpgrp): Remove definition, unused.

3369 Remove unnecessary forward decls.
3371 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3373 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

3375 * dispnew.c (Fsleep_for, sit_for):
3376 * keyboard.c (kbd_buffer_get_event):
3377 * process.c (Faccept_process_output):
3378 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3379 This improves on the previous patch, which introduced a bug
3380 when time_t is unsigned and as wide as intmax_t.
3381 See <http://bugs.gnu.org/9000#51>.
3383 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3399 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
3400 Privately reported by Herbert J. Skuhra.
3401 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
3403 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
3404 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3406 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3409 last argument of make_unibyte_string.
3411 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
3412 language ID in the event parameters.
3414 * w32term.c (w32_read_socket): Put the new keyboard codepage into
3415 event.code, not the obscure "character set ID".

3446 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3448 Support higher-resolution time stamps (Bug#9000).
3449 The time stamps are only nanosecond-resolution at the C level,
3450 since that's the best that any real-world system supports now.
3451 But they are picosecond-resolution at the Lisp level, as that's
3452 easy, and leaves room for future OS improvements.
3454 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3457 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3458 Don't get current time unless it's needed.
3460 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3461 now provides it if it's absent.
3462 (start_atimer): Port to higher-res time stamps.
3463 Check for time stamp overflow. Don't get current time more
3464 often than is needed.
3466 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3467 Include systime.h, not time.h.
3468 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3470 * dired.c: Include stat-time.h.
3471 (Ffile-attributes): File times now have higher resolution.
3473 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3474 (struct image): Timestamp now has higher resolution.
3476 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3477 has at least microseconds now. All uses removed.
3478 (update_frame, update_single_window, update_window, update_frame_1)
3479 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3480 (duration_to_sec_usec): Remove; no longer needed.
3482 * editfns.c (time_overflow): Now extern.
3483 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3484 (float-time, Fformat_time_string, Fcurrent_time_string)

3487 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3488 (decode_time_components, lisp_seconds_argument): New functions.
3489 (make_time): Now static.
3490 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3491 Report an error if the time is invalid, rather than having the caller
3494 * fileio.c: Include <stat-time.h>
3495 (Fcopy_file): Copy higher-resolution time stamps.
3496 Prefer to set the time stamp via a file descriptor if that works.
3497 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3498 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3499 (Fvisited_file_modtime, Fset_visited_file_modtime):
3500 Support higher-resolution time stamps.
3502 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3504 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3506 * image.c (prepare_image_for_display, clear_image_cache)
3507 (lookup_image): Port to higer-resolution time stamps.
3509 * keyboard.c (start_polling, bind_polling_period):
3510 Check for time stamp overflow.
3511 (read_char, kbd_buffer_get_event, timer_start_idle)
3512 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3513 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3514 Port to higher-resolution time stamps. Do not assume time_t is signed.
3515 (decode_timer): New function. Timers are now vectors of length 9,
3516 not 8, to accommodate the picosecond component.
3517 (timer_check_2): Use it.
3519 * nsterm.m (select_timeout, timeval_subtract): Remove.
3520 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3521 as they're a bit more accurate and handle overflow better.
3522 (ns_select): Change prototype to be compatible with pselect.
3523 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3524 * nsterm.h (ns_select): Adjust prototype.
3526 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3527 us-resolution time stamps.
3528 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3530 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3532 * lisp.h (time_overflow): New decl.
3533 (wait_reading_process_output): First arg is now intmax_t, not int,
3534 to accommodate larger waits.
3536 * process.h (struct Lisp_Process.read_output_delay):
3537 Now counts nanoseconds, not microseconds.
3538 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3540 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3541 (wait_reading_process_output):
3542 Port to ns-resolution time stamps.
3543 (Faccept_process_output, wait_reading_process_output):
3544 Check for time stamp overflow. Do not assume time_t is signed.
3545 (select_wrapper): Remove; we now use pselect.
3546 (Fprocess_attributes): Now generates ns-resolution time stamps.
3548 * sysdep.c: Include utimens.h. Don't include utime.h
3549 or worry about struct utimbuf; gnulib does that for us now.
3550 (gettimeofday): Remove; gnulib provides a substitute.
3551 (make_timeval): New function.
3552 (set_file_times): Now sets ns-resolution time stamps.
3553 New arg FD; all uses changed.
3554 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3555 (system_process_attributes):
3556 Now returns ns-resolution time stamp. All uses changed.
3557 Check for time stamp overflow.
3559 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3560 provides a substitute now.
3562 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3563 since it guarantees struct timespec.
3564 (EMACS_TIME): Now struct timespec, so that we can support
3565 ns-resolution time stamps.
3566 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3567 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3568 (EMACS_USECS): Remove.
3569 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3570 so multiply the arg by 1000 before storing it.
3571 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3573 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3574 Port to ns-resolution time stamps.
3575 (EMACS_TIME_NEG_P): Remove; replaced by....
3576 (EMACS_TIME_SIGN): New macro.
3577 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3578 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

3580 (make_timeval, make_lisp_time, decode_time_components): New decls.
3581 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3582 that it mishandled time_t overflow. You can't compare by subtracting!
3583 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3584 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3586 * term.c: Include <sys/time.h>.
3587 (timeval_to_Time): New function, for proper overflow wraparound.

3592 (Fprimitive_undo): Use them when restoring time stamps.
3594 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3595 (w32_get_internal_run_time):
3596 Port to higher-resolution Emacs time stamps.
3597 (ltime): Now accepts single 64-bit integer, as that's more convenient
3600 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3602 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3603 for compatibility with pselect. Support ns-resolution time stamps.
3605 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3607 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3608 Check for time stamp overflow, and support ns-resolution time stamps.
3610 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3611 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3612 (timeval_subtract): Remove; no longer needed.
3613 (XTflash, XTring_bell, x_wait_for_event):
3614 Port to ns-resolution time stamps. Don't assume time_t is signed.
3616 2012-06-22 Chong Yidong <cyd@gnu.org>
3618 * xdisp.c (x_consider_frame_title): Revert last change.
3620 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3622 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3623 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3624 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3625 staticidx goes up to 1597 out of 1600 = 0x640.)
3627 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3629 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3630 Otherwise, the umask might be mistakenly 0 while handling input signals.
3632 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3634 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

3651 (unwind_format_mode_line): Restore them.
3652 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3654 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3655 since tty frames can be explicitly named.
3656 (prepare_menu_bars): Likewise.
3658 * term.c (Ftty_top_frame): New function.
3660 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3662 Port byte-code-meter to modern targets.
3663 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3664 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3665 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3666 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3667 (METER_1, METER_2): Simplify.
3669 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3671 * data.c (Fdefalias): Return `symbol' (bug#11686).
3673 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3675 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3676 gets killed during executing of this function (Bug#11665).
3677 Try to always return Qt when the buffer has been actually killed.
3678 (Vkill_buffer_query_functions): In doc-string say that functions
3679 run by this hook should not change the current buffer.
3681 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3683 Fix recently-introduced process.c problems found by static checking.
3684 * process.c (write_queue_push, write_queue_pop, send_process):

3687 (send_process): Remove unused local.
3689 2012-06-17 Chong Yidong <cyd@gnu.org>

3897 code works fine either way, and efficiency is not a concern here,
3898 as the union type is for debugging, not for production.
3899 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3900 Use an inline function on all platforms when using the union type,
3901 since this is simpler and 'static inline' can be used portably

4045 * doprnt.c (doprnt): Truncate multibyte char correctly.
4046 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4047 would mishandle a string argument "Xc" if X was a multibyte
4048 character of length 2: it would truncate after X's first byte
4049 rather than including all of X.

4132 and 'double' in a couple of places.
4134 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4136 * xdisp.c (handle_stop): Detect whether we have overlay strings
4137 loaded by testing it->current.overlay_string_index to be
4138 non-negative, instead of checking whether n_overlay_strings is
4139 positive. (Bug#11587)

4151 maybe_unify_char, which was the cause of relocation of buffer text
4154 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4156 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4157 for the duration of call to load_charset, to avoid problems with
4158 callers of maybe_unify_char that access buffer text through C
4161 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4162 decrement the inhibition flag, instead of just setting or
4165 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>

4168 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

4170 now that '#define static' has gone away.
4171 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
4172 (gray_bitmap_bits): Remove; no longer needed.

4176 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4178 Clean up __executable_start, monstartup when --enable-profiling.
4179 The following changes affect the code only when profiling.
4180 * dispnew.c (__executable_start): Rename from safe_bcopy.
4181 Define only on platforms that need it.
4182 * emacs.c: Include <sys/gmon.h> when profiling.
4183 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
4184 (__executable_start): Remove decl, since lisp.h does it now.
4185 (safe_bcopy): Remove decl; no longer has that name.
4186 (main): Coalesce #if into single bit of code, for simplicity.
4187 Cast pointers to uintptr_t, since standard libraries want integers
4189 * lisp.h (__executable_start): New decl.
4191 2012-05-31 Glenn Morris <rgm@gnu.org>
4193 * image.c (Fimagemagick_types): Doc fix.

4216 Do not create empty overlays with the evaporate property (Bug#9642).
4217 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4218 Bug#9642, but explicitly check that the buffer the overlay would
4219 be moved to is live and rearrange lines to make sure that errors
4220 will not put the overlay in an inconsistent state.
4221 (Fdelete_overlay): Cosmetics.
4223 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4225 * w32term.c (my_bring_window_to_top): New function.

4231 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4232 by calling BringWindowToTop.
4234 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4235 (WM_EMACS_END): Increase by one.
4237 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4239 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4240 This avoids undefined behavior that might cause the eassert
4241 to not catch an out-of-range value.
4243 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4245 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4246 Update dependencies.

4255 when referring to sectname field in printf format.
4257 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4259 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4260 Only r_alloc_inhibit_buffer_relocation needed to be added;
4261 the others were already declared.
4263 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4264 before checking whether it's out of range. Put the check inside
4266 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4268 2012-05-27 Ken Brown <kbrown@cornell.edu>
4270 * callproc.c (Fcall_process): Restore a line that was accidentally
4271 commented out in the 2011-02-13 change (bug#11547).
4273 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4275 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4276 defined on ralloc.c.
4278 * buffer.c [REL_ALLOC]: Remove prototypes of
4279 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4280 they are now on lisp.h.
4282 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4284 * search.c (search_buffer): Use it to inhibit relocation of buffer
4285 text while re_search_2 is doing its job, because re_search_2 is
4286 passed C pointers to buffer text. (Bug#11519)
4288 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4291 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4292 state after an additional call to move_it_in_display_line_to, keep
4293 the values of it->max_ascent and it->max_descent found for the
4295 (pos_visible_p): Revert the comparison against bottom_y to what it
4296 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4299 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4301 Fix coding-related core dumps with gcc -ftrapv.
4302 The code was computing A - B, where A and B are pointers, and B is
4303 random garbage. This can lead to core dumps on platforms that
4304 have special pointer registers, and it also leads to core dumps on
4305 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4306 A - B only when B is initialized properly.
4307 * coding.c (coding_set_source, coding_set_destination): Return void.
4308 (coding_change_source, coding_change_destinations): New functions,
4309 with the old behaviors of coding_set_source and coding_set_destination.
4310 All callers that need an offset changed to use these new functions.

4319 * xdisp.c (draw_row_with_mouse_face):
4320 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4322 * w32console.c: Include window.h.
4323 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4325 (initialize_w32_display): Initialize mouse-highlight data.
4327 * w32inevt.c: Include termchar.h and window.h.
4328 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4329 moves, call note_mouse_highlight. If help_echo changed, call
4330 gen_help_event to produce help-echo message in the echo area.
4331 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4334 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4336 * lread.c (read1): Simplify slightly to avoid an overflow warning
4337 with GCC 4.7.0 on x86-64.
4339 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4341 * bidi.c (bidi_mirror_char): Revert last change: an int is
4342 definitely wide enough here.
4344 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4346 Fix integer width and related bugs (Bug#9874).

4357 (allocate_pseudovector):
4358 Use int, not EMACS_INT, where int is wide enough.
4359 (inhibit_garbage_collection, Fgarbage_collect):
4360 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

4362 int might not be wide enough.
4363 (bidi_cache_search, bidi_cache_find, bidi_init_it)

4367 (bidi_level_of_next_char, bidi_move_to_visually_next):
4368 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4369 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4370 (Fkill_buffer, Fset_buffer_major_mode)

4376 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4377 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4378 (Foverlay_recenter, last_overlay_modification_hooks_used)
4379 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4380 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4381 (validate_region): Omit unnecessary test for b <= e,
4382 since that's guaranteed by the previous test.
4383 (adjust_overlays_for_delete): Avoid pos + length overflow.
4384 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4385 (report_overlay_modification):
4386 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4387 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4388 Omit pointer cast, which isn't needed anyway, and doesn't work
4389 after the EMACS_INT -> ptrdiff_t change.

4391 * buffer.h: Adjust decls to match defn changes elsewhere.

4396 not int, to avoid needless 32-bit limit on 64-bit hosts.
4397 (exec_byte_code): Use tighter memory-full test, one that checks
4398 for alloca overflow. Don't compute the address of the object just
4399 before an array, as that's not portable. Use EMACS_INT, not
4400 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4401 * callint.c (Fcall_interactively):
4402 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4403 * callproc.c (call_process_kill, Fcall_process):

4413 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4414 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4415 (casify_object): Avoid integer overflow when overallocating buffer.
4416 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4417 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4418 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4419 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4420 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4421 integers are now checked earlier. All uses replaced with XINT.
4423 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4424 For CCL_MapSingle, check that content and value are in int range.
4425 (ccl_driver, Fregister_code_conversion_map):
4426 Check that Vcode_version_map_vector is a vector.
4427 (resolve_symbol_ccl_program): Check that vector header is in range.
4428 Always copy the vector, so that we can check its contents reliably
4429 now rather than having to recheck each instruction as it's being
4430 executed. Check that vector words fit in 'int'.
4431 (ccl_get_compiled_code, Fregister_ccl_program)
4432 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4433 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4434 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4435 contents are in range.
4436 (Fccl_execute_on_string): Check that status is in range.
4437 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4438 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4439 Accept and return EMACS_INT, not int, because callers can pass values
4441 (c_string_width, strwidth, lisp_string_width, chars_in_text)

4445 (string_escape_byte8, Fget_byte):
4446 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4447 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4448 avoid mishandling large integers.
4449 * character.h: Adjust decls to match defn changes elsewhere.

4458 (Fdefine_charset_internal): Check ranges here, more carefully.
4459 Don't rely on undefined behavior with signed left shift overflow.
4460 Don't assume unsigned int fits into fixnum, or that fixnum fits
4461 into unsigned int. Don't require max_code to be a valid fixnum;
4462 that's not true for gb10830 4-byte on a 32-bit host. Allow
4463 invalid_code to be a cons, for the same reason. Require code_offset
4464 to be a character. Avoid int overflow if max_char is close
4466 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4467 this is intended anyway and avoids some undefined behavior.
4468 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4469 INDEX_TO_CODE_POINT, as that's what it expects.
4470 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4471 * charset.h (DECODE_CHAR): Return int, not unsigned;
4472 this is what was intended anyway, and it avoids undefined behavior.
4473 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4474 integer-overflow issues.
4475 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4476 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4477 where the argument is EMACS_INT, and this behavior is not intended.
4478 * chartab.c (Fmake_char_table, Fset_char_table_range)
4479 (uniprop_get_decoder, uniprop_get_encoder):
4480 Don't assume fixnum fits in int.
4481 * cmds.c (move_point): New function, that does the gist of
4482 Fforward_char and Fbackward_char, but does so while checking
4483 for integer overflow more accurately.
4484 (Fforward_char, Fbackward_char): Use it.
4485 (Fforward_line, Fend_of_line, internal_self_insert)
4486 (internal_self_insert):
4487 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4488 Fix a FIXME, by checking for integer overflow when calculating
4489 target_clm and actual_clm.

4524 Don't access memory outside of the args array.
4525 (Fdefine_coding_system_internal): Check for charset-id overflow.
4526 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4527 result of ENCODE_CHAR.

4546 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
4547 Do not attempt to compute the address of the object just before a
4548 buffer; this is not portable.
4550 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4551 (Faset): Use int, not EMACS_INT, where int is wide enough.
4552 (Fstring_to_number): Don't assume fixnums fit in int.

5305 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5306 and right-margin display specs even if the spec is invalid or we
5307 are on a TTY, and thus unable to display on the fringes.
5308 That's because the text with the property will not be displayed anyway,
5309 so we need to signal to the caller that this is a "replacing"
5310 display spec. This fixes display when the spec is invalid or we
5313 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5315 * unexaix.c (make_hdr): Fix typo in prototype.
5316 This bug broke the build on AIX. Problem reported by Gilles Pion.
5318 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5320 * keyboard.c (kbd_buffer_get_event): Read special events also in
5321 batch mode. (Bug#11415)
5323 2012-05-12 Glenn Morris <rgm@gnu.org>
5325 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5327 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5329 * lisp.mk (lisp): Add newcomment.elc.
5331 2012-05-12 Glenn Morris <rgm@gnu.org>
5333 * Makefile.in (MKDIR_P): New, set by configure.
5334 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5336 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5338 Remove unused function hourglass_started.
5339 * dispextern.h (hourglass_started):
5340 * w32fns.c (hourglass_started):
5341 * xdisp.c (hourglass_started): Remove.
5343 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5345 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5346 Update dependencies.
5348 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5350 * xgselect.c (xg_select): Put maxfds+1 into a var.
5351 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5353 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5355 2012-05-10 Dave Abrahams <dave@boostpro.com>
5357 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5358 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5360 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5362 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5363 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5364 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5365 Initialize xd_registered_buses.
5367 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5369 Untag more efficiently if USE_LSB_TAG.
5370 This is based on a proposal by YAMAMOTO Mitsuharu in
5371 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5372 For an admittedly artificial (nth 8000 longlist) benchmark on
5373 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5374 Emacs's overall text size by 1%.
5375 * lisp.h (XUNTAG): New macro.
5376 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5377 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5378 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5379 * eval.c (Fautoload):
5380 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5381 * frame.h (XFRAME): Use XUNTAG.
5383 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5384 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5385 Remove unportable assumptions about print widths of types like
5387 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5388 intptr_t when converting between pointer and integer, to avoid GCC
5389 warnings about wrong width.
5391 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5393 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5394 stack for each reader_thread, instead of defaulting to 8MB
5395 determined by the linker. This avoids failures in creating
5396 subprocesses on Windows 7, see the discussion in this thread:
5397 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5399 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5401 Fix up display of the *Minibuf-0* buffer in the mini window.
5402 * keyboard.c (read_char): Don't clear the echo area if there's no
5404 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5405 contents of *Minibuf-0*) if there's no message displayed in its stead.
5407 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5409 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5412 2012-05-06 Chong Yidong <cyd@gnu.org>
5414 * lisp.mk (lisp): Update.
5416 2012-05-05 Jim Meyering <meyering@redhat.com>
5418 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5420 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5422 * data.c (PUT_ERROR): New macro.
5423 (syms_of_data): Use it. Add new error type `user-error'.
5424 * undo.c (user_error): New function.
5425 (Fprimitive_undo): Use it.
5426 * print.c (print_error_message): Adjust print style for `user-error'.
5427 * keyboard.c (user_error): New function.
5428 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5430 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5432 Do not limit current-time-string to years 1000..9999.
5433 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5434 (Fcurrent_time_string): Support any year that is supported by the
5435 underlying localtime representation. Don't use asctime, as it
5436 has undefined behavior for years outside the range -999..9999.
5438 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5440 Fix race conditions involving setenv, gmtime, localtime, asctime.
5441 Without this fix, interrupts could mess up code that uses these
5442 nonreentrant functions, since setting TZ invalidates existing
5443 tm_zone or tzname values, and since most of these functions return
5444 pointers to static storage.
5445 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5446 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5447 Grow the critical sections to include not just invoking
5448 localtime/gmtime, but also accessing these functions' results
5449 including their tm_zone values if any, and any related TZ setting.
5450 (format_time_string): Last arg is now struct tm *, not struct tm **,
5451 so that the struct tm is saved in the critical section.
5452 All callers changed. Simplify allocation of initial buffer, partly
5453 motivated by the fact that memory allocation needs to be outside
5454 the critical section.
5456 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5458 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5459 with RESET_INTERVAL.
5461 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5462 Remove duplicated buffer name initialization.
5464 2012-05-02 Jim Meyering <jim@meyering.net>
5466 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5468 * xfns.c (x_window): Use xstrdup (Bug#11375).
5470 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5472 * xdisp.c (pos_visible_p): If already at a newline from the
5473 display string before the 'while' loop, don't walk back the glyphs
5474 from it3.glyph_row. Solves assertion violation when the display
5475 string begins with a newline (egg.el). (Bug#11367)
5477 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5479 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5482 2012-05-01 Glenn Morris <rgm@gnu.org>
5484 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5485 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5486 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5487 All were removed before 23.1.
5489 * dispnew.c: Remove HAVE_LIBNCURSES test;
5490 it is always true on relevant platforms.
5492 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5493 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5495 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5497 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5499 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5500 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5503 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5505 Do not avoid creating empty evaporating overlays (Bug#9642).
5506 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5507 That is, do not delete an evaporating overlay if it becomes
5508 empty after its bounds are adjusted to fit within its buffer.
5509 This fix caused other problems, and I'm reverting it until we get
5510 to the bottom of them.
5512 2012-04-27 Chong Yidong <cyd@gnu.org>
5514 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5516 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5518 * xdisp.c (pos_visible_p): If the window start position is beyond
5519 ZV, start the display from buffer beginning. Prevents assertion
5520 violation in init_iterator when the minibuffer window is scrolled
5523 * window.c (window_scroll_pixel_based): Likewise.
5525 2012-04-27 Chong Yidong <cyd@gnu.org>
5527 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5529 2012-04-27 Glenn Morris <rgm@gnu.org>
5531 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5532 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5534 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5536 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5537 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5539 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5541 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5542 display element, check also the underlying string or buffer
5543 character. (Bug#11341)
5545 * w32menu.c: Include w32heap.h.
5546 (add_menu_item): If the call to AppendMenuW (via
5547 unicode_append_menu) fails, disable Unicode menus only if we are
5548 running on Windows 9X/Me.
5550 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5552 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5553 (xgetint): Add missing shift for LSB tags.
5555 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5557 * keyboard.c (read_char): Don't wipe echo area for select window
5558 events: These might get delayed via `mouse-autoselect-window'
5561 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5563 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5564 manipulation of :loaded-from data.
5566 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5568 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5569 now a cons (bug#11311).
5571 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5573 Do not create empty overlays with the evaporate property (Bug#9642).
5574 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5575 if it becomes empty after its bounds are adjusted to fit within
5576 its buffer. Without this fix, in a nonempty buffer (let ((o
5577 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5578 yields an empty overlay that has the evaporate property, which is
5579 not supposed to happen.
5581 Fix minor GTK3 problems found by static checking.
5582 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5583 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5584 (struct _EmacsFixedClass, emacs_fixed_get_type):

5592 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5593 (EMACS_FIXED_GET_CLASS): Remove; unused.
5594 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5596 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5597 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5599 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5601 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5602 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5603 (__malloc_size_t, __malloc_ptrdiff_t):
5604 Remove. All uses removed, replaced by the definiens if needed,
5605 since we can assume C89 or better now.
5606 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5607 (protect_malloc_state, align, get_contiguous_space)
5608 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5614 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5615 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5616 Define using prototypes, not old style.
5617 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5618 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5619 (align): Don't assume that signed integer overflow wraps around.
5620 Omit unused local var.
5621 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5622 (_free_internal_nolock, memalign, mallochook, reallochook):

5626 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5628 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5630 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

5681 * alloc.c: Handle unusual debugging option combinations.
5682 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5683 since the two debugging options are incompatible.
5684 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

5694 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5696 * sysdep.c [__FreeBSD__]: Minor cleanups.
5697 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5698 Use Emacs indenting style more consistently. Avoid some casts.
5699 Use 'double' consistently rather than mixing 'float' and 'double'.
5701 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5703 * sysdep.c (list_system_processes, system_process_attributes):

5738 row, return zero immediately.
5739 (try_cursor_movement): If inside continuation line, don't back up
5740 farther than the first row after the header line, if any.
5741 Don't consider the header-line row as "partially visible", even if
5742 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

5779 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5780 New extern decls, to avoid calling undeclared functions.
5781 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5782 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5783 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5784 (NEED_MEM_INSERT): New macro.
5785 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5786 Remove one incorrect comment and fix another.

5792 (r_alloc_sbrk): Now static.
5794 Improve ralloc.c interface checking.
5795 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

5800 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5801 Remove decls. This fixes an "It stinks!".

5805 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5807 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5818 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5820 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5821 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5822 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5823 * s/netbsd.h, s/sol2-6.h:
5824 Remove definition of GC_MARK_STACK, since the default now works.
5825 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5826 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5827 no longer the default.
5828 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5830 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5832 * lread.c (lisp_file_lexically_bound_p):

5840 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5842 * nsterm.m (constrainFrameRect): Always constrain when there is only
5843 one screen (Bug#10962).
5845 2012-04-13 Ken Brown <kbrown@cornell.edu>

5853 2012-04-11 Daniel Colascione <dancol@dancol.org>
5855 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5856 against is gone. It's better to use vfork now so that when Cygwin
5857 gains a new, working vfork, we use it automatically (bug#10398).
5859 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5875 (handle_interrupt): Use it.
5877 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5879 * w32.c (w32_delayed_load): Record the full path of the library
5880 being loaded (bug#10424).
5882 2012-04-09 Glenn Morris <rgm@gnu.org>
5884 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5885 not just in the obarray, before snarfing them. (Bug#11036)
5887 * Makefile.in ($(leimdir)/leim-list.el):
5888 Pass EMACS rather than BUILT_EMACS.

5897 Add convenience `GNUTLS_LOG2i' macro.
5899 * gnutls.c (gnutls_log_function2i): Convenience log function.
5900 (emacs_gnutls_read): Use new log functions,
5901 `gnutls_handshakes_tried' process member, and

5903 attempts per process (connection).
5905 2012-04-09 Chong Yidong <cyd@gnu.org>

5912 * minibuf.c (Fread_variable): Callers changed.
5914 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5916 * xdisp.c (set_cursor_from_row): If the display string appears in
5917 the buffer at position that is closer to point than the position
5918 after the display string, display the cursor on the first glyph of
5919 the display string. Fixes cursor display when a 'display' text
5920 property immediately follows invisible text. (Bug#11094)
5922 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5924 composite.c: use 'double' consistently
5925 * composite.c (get_composition_id): Use 'double' consistently
5926 instead of converting 'float' to 'double' and vice versa; this is
5927 easier to understand and avoids a GCC warning.
5929 2012-04-09 Glenn Morris <rgm@gnu.org>
5931 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5932 preparation for dumping it with emacs. (Bug#4789)

5954 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5955 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5956 objects, as mark_maybe_pointer will catch them otherwise.
5957 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5958 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5960 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5962 Fix typo that broke non-Windows builds.
5963 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5965 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5967 Support building on MS-Windows with libxml2.
5969 * makefile.w32-in (OBJ2): Add xml.$(O).

5973 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5974 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5975 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5976 [!WINDOWSNT]: New macros.
5977 (init_libxml2_functions, libxml2_loaded_p): New functions.
5978 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5979 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5980 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5981 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5983 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5984 Call init_libxml2_functions before calling libxml2 functions.
5985 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5987 * emacs.c: Don't include libxml/parser.h.
5988 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5989 xmlCleanupParser directly.
5991 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5993 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5995 * indent.c (Fvertical_motion): If there is a display string at
5996 point, use it.vpos to compute how many lines to backtrack after

6001 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
6002 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
6003 about subtle differences between FETCH_CHAR* and STRING_CHAR*
6004 macros related to unification of CJK characters. For the details,
6005 see the discussion following the message here:
6006 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
6008 2012-04-04 Chong Yidong <cyd@gnu.org>
6010 * keyboard.c (Vdelayed_warnings_list): Doc fix.
6012 2012-04-01 Eli Zaretskii <eliz@gnu.org>
6014 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

6022 2012-03-31 Eli Zaretskii <eliz@gnu.org>
6024 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
6025 position we get to after a call to move_it_to fails the
6026 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
6027 only if we wind up in a string from display property. (Bug#11063)
6029 * window.c (Fdelete_other_windows_internal): Invalidate the row
6030 and column information about mouse highlight, so that redisplay
6031 restores it after reallocating the glyph matrices. (Bug#7464)
6033 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
6034 string comes from a `display' text property, use the buffer
6035 position of that property as if we actually saw that position in
6037 (move_it_by_lines): Remove the assertion that
6038 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6039 violated when there's a before-string at the beginning of a line.
6042 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6044 * xdisp.c (append_space_for_newline): If the default face was
6045 remapped, use the remapped face for the appended newline.
6046 (extend_face_to_end_of_line): Use the remapped default face for
6047 extending the face to the end of the line.
6048 (display_line): Call extend_face_to_end_of_line when the default
6049 face was remapped. (Bug#11068)
6051 2012-03-29 Eli Zaretskii <eliz@gnu.org>
6053 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

6081 * dispextern.h (struct glyph): Change the bit length of
6082 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6084 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6086 * s/ms-w32.h (tzname): Include time.h before redirecting to
6087 _tzname. Fixes the MSVC build. (Bug#9960)
6089 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
6091 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6094 * xterm.c (XTread_socket): Only modify handling_signal if
6095 !SYNC_INPUT. (Bug#11080)
6097 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6099 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6100 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6101 when fetching a multibyte character consumes more bytes than
6102 CHAR_BYTES returns, due to unification of CJK characters in
6103 string_char. (Bug#11073)
6105 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6107 * process.c (wait_reading_process_output): Handle pty disconnect

6141 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6142 that is not from display property, accept the row as a "cursor
6143 row" if one of the string's character has a non-nil `cursor'
6144 property. Fixes cursor positioning when there are newlines in
6145 overlay strings, e.g. in icomplete.el. (Bug#11035)
6147 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

6153 * eval.c (inhibit_lisp_code): Rename from
6154 inhibit_window_configuration_change_hook; move from window.c.
6156 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6157 * window.c (run_window_configuration_change_hook)
6158 (syms_of_window): Callers changed.
6160 2012-03-11 Chong Yidong <cyd@gnu.org>

6173 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6175 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6177 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6178 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6181 2012-03-03 Glenn Morris <rgm@gnu.org>
6183 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6185 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6187 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6188 position past the first glyph_row that ends at ZV. (Bug#10902)
6189 (redisplay_window, next_element_from_string): Fix typos in
6191 (redisplay_window): Pass to move_it_vertically the margin in
6192 pixels, not in screen lines.
6194 2012-03-02 Glenn Morris <rgm@gnu.org>
6196 * buffer.c (buffer-list-update-hook): Doc fix.
6198 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6200 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6201 push_it before setting up the iterator for the first overlay
6202 string, even if we have an empty string loaded.
6203 (next_overlay_string): If there's an empty string on the iterator
6204 stack, pop the stack. (Bug#10903)
6206 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6208 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6209 Suggested by Stefan Monnier in
6210 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6211 * alloc.c (widen_to_Lisp_Object): New static function.
6212 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6213 and widening them to Lisp_Objects. This would work even if
6214 USE_LSB_TAG is defined and wide integers are used, which might
6215 happen in a future version of Emacs.
6217 2012-02-25 Chong Yidong <cyd@gnu.org>
6219 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6222 * xselect.c (Fx_selection_exists_p): Doc fix.
6223 (x_clipboard_manager_save_all): Print an informative message
6224 before saving to clipboard manager.
6226 2012-02-24 Chong Yidong <cyd@gnu.org>

6255 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
6256 when computing $valmask.
6258 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6259 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6260 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6261 It's useless in that case, and it can cause problems on hosts
6262 that allocate halves of EMACS_INT values separately.
6263 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6264 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6265 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6266 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6267 it avoids undefined behavior on hosts where shifting right by more
6268 than the word width has undefined behavior.

6394 * character.c (char_width): Return EMACS_INT, not int.
6395 (char_width, c_string_width): Check for overflow when
6396 computing the width; this is possible now that individual
6397 characters can have unbounded width. Problem introduced

7056 to 4 (xorl, subq, cmpq, setbe).
7057 * alloc.c (pure): Always extern now, since that's the
7058 VIRT_ADDR_VARIES behavior.
7059 (PURE_POINTER_P): Use a single comparison, not two, for
7060 consistency with the new puresize.h.
7061 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

7070 behave as if the cursor position were at the window margin.
7072 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7073 and the cursor position is out of bounds, behave as if the cursor
7074 position were at the window margin. (Bug#10075)
7076 2011-11-18 Chong Yidong <cyd@gnu.org>
7078 * window.c (Fwindow_combination_limit): Make first argument

7104 * dispnew.c (verify_row_hash): Call row_hash for computing the
7105 hash code of a row, instead of duplicating code from xdisp.c.
7107 * dispextern.h (row_hash): Add prototype.
7109 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
7111 * frame.c (delete_frame): Don't delete the terminal when the last

7143 * image.c (imagemagick_load_image): Fix typo.
7145 2011-11-14 Eli Zaretskii <eliz@gnu.org>
7147 * xdisp.c (display_line): Move the call to
7148 highlight_trailing_whitespace before the call to
7149 compute_line_metrics, since the latter needs to see the final
7150 faces of all the glyphs to compute ROW's hash value.

7215 The trivial performance wins aren't worth the portability hassles; see
7216 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
7218 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

7251 2011-11-07 Martin Rudalics <rudalics@gmx.at>
7253 * window.h: Declare delete_all_child_windows instead of

7266 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
7267 This is also needed for porting to any host where GC_MARK_STACK is
7268 not GC_MAKE_GCPROS_NOOPS.
7269 (which_symbols): Use it.
7271 2011-11-07 Kenichi Handa <handa@m17n.org>

7284 * xmenu.c (cleanup_widget_value_tree): New function.
7285 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

7290 Fix some portability problems with 'inline'.
7291 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
7292 (window_box_width, window_box_left, window_box_left_offset)
7293 (window_box_right, window_box_right_offset): Declare extern.
7294 Otherwise, these inline functions do not conform to C99 and
7295 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7296 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7297 * intervals.c (adjust_intervals_for_insertion)
7298 (adjust_intervals_for_deletion): Now extern, because otherwise the
7299 extern inline functions 'offset_intervals' couldn't refer to it.
7300 (static_offset_intervals): Remove.
7301 (offset_intervals): Rewrite using the old contents of
7302 static_offset_intervals. The old version didn't conform to C99
7303 because an extern inline function contained a reference to an
7304 identifier with static linkage.
7306 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
7308 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

7326 (Fwindow_vscroll): Doc fix.
7327 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
7328 argument, since it makes no sense to pass a live window and for
7329 consistency with window-child.

7359 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
7360 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
7361 Move terminal->reference_count++ just before making the frame official

7475 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
7476 so that this new function doesn't get optimized away by a
7477 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
7479 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>

7508 condition to clear the mouse face.
7510 2011-10-28 Chong Yidong <cyd@gnu.org>

7539 (w32font_open_internal, compute_metrics):
7540 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7541 instead of calling the "wide" APIs directly.
7543 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

7559 non-NULL, regardless of GNUTLS_INITSTAGE.
7560 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7561 an error. Set process slots as soon as we allocate them.

7608 (bidi_resolve_weak): Don't enter the expensive loop if the current
7609 position is before next_en_pos. Record the bidi type of the first
7610 non-ET, non-BN character we find, in addition to its position.
7611 (bidi_level_of_next_char): Invalidate next_en_type when
7612 next_en_pos is over-stepped.
7614 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7616 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7617 * editfns.c: Rewrite current-time-zone so that it invokes
7618 the equivalent of (format-time-string "%Z") to get the time zone name.
7619 This fixes a bug when the time zone name contains characters that
7620 need converting from the system time locale to Emacs internal format.
7621 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7622 that patch fixed format-time-string to do the conversion, but
7623 I forgot to fix current-time-zone.
7624 (format_time_string): New function, containing most of
7625 what Fformat_time_string used to contain.
7626 (Fformat_time_string): Rewrite in terms of format_time_string.
7627 This doesn't change this function's behavior.
7628 (current-time-zone): Rewrite to use format_time_string.
7629 This fixes the bug reported by Michael Schierl in
7630 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7631 Jason Rumney's 2007-06-07 change worked around this bug, but
7633 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7635 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7637 * xdisp.c (start_display): If the character at POS is displayed
7638 via a display vector, reset IT->current.dpvec_index to zero.
7639 (try_window_reusing_current_matrix): If a line ends in a display
7640 vector or the next line starts in a display vector, continue
7641 redrawing the window even though the character position of
7642 start_row was reached.
7645 2011-10-18 Chong Yidong <cyd@gnu.org>
7647 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7648 with nobreak-char-display too.
7650 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7652 Fix part 3 of bug#9771.
7653 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7654 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7655 non-neutral characters if the current character is a paragraph
7656 separator (a.k.a. Newline). This avoids running the same
7657 expensive loop twice, once when we consume the preceding newline
7658 and the other time when the line actually needs to be displayed.
7659 Avoid the loop when we see neutrals on the base embedding level
7660 following a character whose directionality is the same as the
7661 paragraph's. This avoids running the expensive loop when a line
7662 ends in a long sequence of neutrals, like control characters.
7663 Add assertion against STRONG_AL type. Slightly rearrange code
7664 that determines the type of a neutral given the first non-neutral
7666 (bidi_level_of_next_char): Set next_en_pos to zero when
7667 invalidating its info.
7669 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7671 * xdisp.c (push_display_prop): Determine whether to record string
7672 or buffer position by IT->string, not by IT->method. Allow
7673 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7674 (move_it_vertically_backward): Don't look for character position
7675 immediately after the newline when in a continuation line.
7678 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7680 * window.c (coordinates_in_window): Rewrite and delabelize
7681 vertical border check. (Bug#5357) (Bug#9618)
7683 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7685 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7686 errors in XSetWindowBorder (bug#9310).
7688 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7690 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7691 avoid crash when xmalloc overrun checking is enabled.
7693 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7695 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7696 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7697 cursor motion with <left> and <right> arrow keys.
7699 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7700 some callers set that themselves.
7702 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7704 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7705 display string and the previous row comes from the same string and
7706 is empty. (Bug#9739) (Bug#9738)
7708 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7710 * doc.c (get_doc_string): Encode file name (bug#9735).
7712 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7714 * bidi.c (bidi_level_of_next_char):
7715 * xdisp.c (get_visually_first_element): Remove old incorrect
7716 comments regarding the Unicode Line Separator character.
7718 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7720 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7722 * alloc.c (Fgc_status): Do not access beyond zombies array
7723 boundary if nzombies > MAX_ZOMBIES.
7724 * alloc.c (dump_zombies): Add missing format specifier.
7726 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7728 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7729 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7731 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7732 Some packages use them to denote characters with modifiers.
7734 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7736 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7737 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7738 matching a pp-number. Rename parameter var to var1.
7740 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7742 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7744 2011-10-08 Glenn Morris <rgm@gnu.org>
7746 * callint.c (Fcall_interactively): Give a more explicit error for the
7747 'c' case with a non-character input. (Bug#8479)
7749 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7751 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7753 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7754 lines that are hscrolled on the left.
7756 * dispnew.c (buffer_posn_from_coords): Account for a possible
7757 presence of header-line. (Bug#4426)
7759 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7761 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7762 Don't advertise functionality which we discourage or doesn't work.
7764 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7766 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7767 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7768 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7769 this makes Emacs dump core during garbage collection on rare
7770 occasions. sizeof is obviously inferior to offsetof here, so
7771 stick with offsetof.
7772 (GC_POINTER_ALIGNMENT): New macro.
7773 (mark_memory): Omit 3rd (offset) arg; caller changed.
7774 Don't assume EMACS_INT alignment is the same as pointer alignment.
7776 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7778 * keyboard.c (read_key_sequence_remapped): New var.
7779 (read_key_sequence): Compute remapping in the right buffer.
7780 (command_loop_1): Use read_key_sequence's remapping directly.
7782 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7784 * dired.c (file_name_completion): Don't expand file name.
7785 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7786 before checking file name handler.
7788 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7789 they've been requested explicitly (bug#9591).
7791 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7793 * keymap.c (Fsingle_key_description): Use make_specified_string
7794 instead of build_string to build string from push_key_description.
7797 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7799 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7800 This fixes a Y2038 bug on 64-bit hosts.
7801 * buffer.c (reset_buffer):
7802 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7803 (Fclear_buffer_auto_save_failure):
7804 Use 0, not -1, to represent an unset failure time, since time_t
7805 might not be signed.
7807 Remove dependency on glibc malloc internals.
7808 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7809 Move back here from lisp.h, but with their new implementations.
7810 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7811 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7812 * charset.c (charset_table_init): New static var.
7813 (syms_of_charset): Use it instead of xmalloc. This removes a
7814 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7815 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7816 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7817 Move back to alloc.c.
7818 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7819 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7821 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7823 * nsterm.m (windowDidResize): Call x_set_window_size only when
7824 ns_in_resize is true. Otherwise set pixelwidth/height and
7825 call change_frame_size (Bug#9628).
7827 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7829 Port --enable-checking=all to Fedora 14 x86-64.
7830 * charset.c (syms_of_charset): Also account for glibc malloc's
7831 internal overhead when calculating the initial malloc maximum.
7833 Port --enable-checking=all to Fedora 14 x86.
7834 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7836 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7837 (overrun_check_realloc, overrun_check_free):
7838 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7839 That way, xmalloc returns a properly-aligned pointer even if
7840 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7841 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7842 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7843 into account when calculating the initial malloc maximum.
7844 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7845 Move here from alloc.c, so that charset.c can use it too.
7846 Properly align; the old code wasn't right for common 32-bit hosts
7847 when configured with --enable-checking=all.
7848 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7849 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7851 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7853 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7856 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7858 * xdisp.c (compute_display_string_end): If there's no display
7859 string at CHARPOS, return -1.
7861 * bidi.c (bidi_fetch_char): When compute_display_string_end
7862 returns a negative value, treat the character as a normal
7863 character not covered by a display string. (Bug#9624)
7865 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7867 * lread.c (Fread_from_string): Fix typo in docstring.
7869 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7871 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7872 newline, reseat the iterator instead of bidi-iterating there one
7873 character at a time. (Bug#9610)
7874 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7875 TO_CHARPOS if the bidi iterator is at base embedding level.
7877 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7879 * lread.c (readevalloop): Use correct code for NBSP.
7880 (read1): Likewise. (Bug#9608)
7882 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7884 * dbusbind.c (Fdbus_register_signal): When service is not
7885 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7887 2011-09-25 Glenn Morris <rgm@gnu.org>
7889 * buffer.c (truncate-lines): Doc fix.
7891 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7893 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7894 (Fset_window_next_buffers): Doc fix.
7896 2011-09-24 Glenn Morris <rgm@gnu.org>
7898 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7900 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7902 Fix minor problems found by static checking.
7903 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7904 * indent.c (Fvertical_motion): Fix == vs = typo.
7906 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7908 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7909 Default value is now t. Doc fix.
7911 * indent.c (Fvertical_motion): Compute and apply the overshoot
7912 logic when moving up, not only when moving down. Fix the
7913 confusing name and values of the it_overshoot_expected variable;
7914 logic changes accordingly. (Bug#9254) (Bug#9549)
7916 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7917 CHARPOS is covered by a display string which includes newlines.
7918 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7919 is covered by a display string with embedded newlines.
7921 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7923 * dbusbind.c (Fdbus_register_signal): Add match rule to
7924 Vdbus_registered_objects_table. (Bug#9581)
7925 (Fdbus_register_method, Vdbus_registered_objects_table):
7928 2011-09-24 Jim Meyering <meyering@redhat.com>
7930 do not ignore write error for any output size
7931 The previous change was incomplete.
7932 While it makes emacs --batch detect the vast majority of stdout
7933 write failures, errors were still ignored whenever the output size is
7934 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7935 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7936 && echo FAIL: ignored write error
7937 FAIL: ignored write error
7938 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7939 && echo FAIL: ignored write error
7940 FAIL: ignored write error
7941 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7943 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7945 * emacs.c (Fkill_emacs): In noninteractive mode exit
7946 non-successfully if a write error occurred on stdout. (Bug#9574)
7948 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7950 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7953 * dispextern.h (struct it): Update the comment documenting what
7956 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7958 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7959 a display string, extend search for cursor position to end of row.
7960 (find_row_edges): If the row ends in a newline from a display
7961 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7962 Handle the case of a display string with multiple newlines.
7963 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7964 non-empty line. Fixes confusing cursor motion with arrow keys at
7965 the beginning of a line that starts with whitespace.
7967 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7969 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7972 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7974 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7977 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7979 * xdisp.c (display_line): Record maximum and minimum buffer
7980 positions even if no glyphs were produced (e.g., by a zero-width
7981 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7982 buffer positions that will be removed from the glyph row because
7984 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7985 column is beyond frame width: don't subtract 1 "pixel" when
7986 computing width of the stretch.
7987 (reseat_at_next_visible_line_start): Undo the change made on
7988 2011-09-17 that saved paragraph information and restored it after
7989 the call to `reseat'. (Bug#9545)
7991 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7993 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7994 and turn window cursor on if cleared (Bug#9415).
7996 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7998 * search.c (boyer_moore): Take unibyte characters from pattern
7999 literally. (Bug#9458)
8001 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8003 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
8005 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
8007 Fix minor problem found by static checking.
8008 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
8009 initialized, to pacify gcc -Wuninitialized.
8011 * fileio.c: Report proper errno when syscall falls.
8012 (Finsert_file_contents): Save and restore errno,
8013 so that report_file_error outputs the correct diagnostic.
8014 (Fwrite_region) [CLASH_DETECTION]: Likewise.
8016 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8018 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
8020 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8022 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
8023 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
8025 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8027 * xdisp.c (reseat_at_next_visible_line_start): Keep information
8028 about the current paragraph and restore it after the call to reseat.
8030 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
8031 (bidi_find_paragraph_start): Search back for paragraph beginning
8032 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
8033 (bidi_move_to_visually_next): Only trigger paragraph-related
8034 computations when the last character is a newline or at EOB, not
8035 just any NEUTRAL_B. (Bug#9470)
8037 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
8038 truncated lines if point is covered by a display string. (Bug#9524)
8040 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
8042 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8043 (cons_to_x_long): New function.
8044 (lisp_data_to_selection_data): Use it. Correct the test for
8045 short-versus-long data; it was negated. Break out of vector
8046 loop, for efficiency, when a long datum is discovered.
8048 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8050 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8052 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8054 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
8055 GCC PR/17406) by declaring this function with external scope.
8057 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8059 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
8060 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
8062 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
8064 * editfns.c (Fformat): Correctly handle text properties on "%%".
8066 2011-09-15 Eli Zaretskii <eliz@gnu.org>
8068 * xterm.c (x_draw_composite_glyph_string_foreground):
8069 * w32term.c (x_draw_composite_glyph_string_foreground):
8070 * term.c (encode_terminal_code):
8071 * composite.c (composition_update_it, get_composition_id):
8072 * xdisp.c (get_next_display_element)
8073 (fill_composite_glyph_string): Add comments about special meaning
8074 of TAB characters in a composition.
8076 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8078 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8079 This occurs when processing a multibyte format.
8080 Problem reported by Wolfgang Jenker.
8082 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8084 * xdisp.c (try_cursor_movement): Only check for exact match if
8085 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8087 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8089 Remove unused external symbols.
8090 * dispextern.h (calc_pixel_width_or_height): Remove decl.
8091 * xdisp.c (calc_pixel_width_or_height): Now static.
8092 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
8093 * indent.c (check_display_width):
8094 * w32term.c: Fix comment to match code.
8095 * xterm.c, xterm.h (x_catching_errors): Remove.
8097 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8099 * xselect.c: Use signed conversions more consistently (Bug#9498).
8100 (selection_data_to_lisp_data): Assume incoming selection data are
8101 signed integers, not unsigned. This is to be consistent with
8102 outgoing selection data, which was modified to use signed integers
8103 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8104 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8105 expects long, not unsigned long.
8107 2011-09-14 Eli Zaretskii <eliz@gnu.org>
8109 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
8110 computation of loop end. Reported by Johan Bockgård
8113 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
8115 * frame.c (Fother_visible_frames_p): Function deleted.
8117 2011-09-12 Eli Zaretskii <eliz@gnu.org>
8119 * indent.c (compute_motion): Process display vector front to back
8120 rather than the other way around. (Bug#2496)
8122 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
8124 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
8126 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
8128 * minibuf.c (Fread_from_minibuffer): Doc fix.
8130 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8132 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8133 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8135 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8137 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8138 value for non-existent files.
8140 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8142 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8143 set its "size" to -1. This will set the modtime_size field of
8144 the corresponding buffer to -1, which is what
8145 verify-visited-file-modtime expects for files that do not exist.
8148 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8150 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8152 * lisp.h: ... from here. push_key_description is no longer
8153 defined in keyboard.c, so its declaration should not be in
8154 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8155 logically belongs with push_key_description.
8157 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8159 * buffer.h: Include <sys/types.h> instead of <time.h>.
8160 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8161 Problem reported by Herbert J. Skuhra.
8163 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8165 * xml.c (parse_region): Make the parsing work for
8166 non-comment-starting XML files again (bug#9144).
8168 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8170 * image.c (gif_load): Fix calculation of bottom and right corner.
8173 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8175 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8176 redisplay in small windows.
8178 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8180 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8182 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8184 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8185 Operate on live windows only.
8187 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8189 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8191 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8193 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8194 only under bidi iteration.
8196 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8198 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8200 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8202 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8203 Without this fix, the command to link temacs failed due to an
8204 undefined symbol __builtin_isnan. This is because
8205 /usr/include/iso/math_c99.h #defines isnan(x) to
8206 __builtin_isnan(x), but the bundled gcc, which identifies itself
8207 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8209 * floatfns.c (isnan): #undef, and then #define to a clone of
8211 (Fisnan): Always define, since it's always available now.
8212 (syms_of_floatfns): Always define isnan at the Lisp level.
8214 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8216 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8218 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8220 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8221 The previous code assumed that file offsets (off_t values) fit in
8222 EMACS_INT variables, which is not true on typical 32-bit hosts.
8223 The code messed up by falsely reporting buffer overflow in cases
8224 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8225 when "big" contains more than 2**29 bytes, even though this
8226 inserts just one byte and does not overflow the buffer.
8227 (Finsert_file_contents): Store file offsets as off_t
8228 values, not as EMACS_INT values. Check for overflow when
8229 converting between EMACS_INT and off_t. When checking for
8230 buffer overflow or for overlap, take the offsets into account.
8231 Don't use EMACS_INT for small values where int suffices.
8232 When checking for overlap, fix a typo: ZV was used where
8233 ZV_BYTE was intended.
8234 (Fwrite_region): Don't assume off_t fits into 'long'.
8235 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8237 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8239 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8241 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8243 sprintf-related integer and memory overflow issues (Bug#9412).
8245 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8246 (esprintf, exprintf, evxprintf): New functions.
8247 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8248 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8249 (modify_event_symbol): Do not assume that the length of
8250 name_alist_or_stem is safe to alloca and fits in int.
8251 (Fexecute_extended_command): Likewise for function name and binding.
8252 (Frecursion_depth): Wrap around reliably on integer overflow.
8253 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8254 since some callers pass EMACS_INT values.
8255 (Fsingle_key_description): Don't crash if symbol name contains more
8256 than MAX_ALLOCA bytes.
8257 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8258 (get_minibuffer): Arg is now EMACS_INT, not int.
8259 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8260 (esprintf, exprintf, evxprintf): New decls.
8261 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8263 * dbusbind.c (signature_cat): New function.
8264 (xd_signature, Fdbus_register_signal):
8265 Do not overrun buffer; instead, report string overflow.
8267 * dispnew.c (add_window_display_history): Don't overrun buffer.
8268 Truncate instead; this is OK since it's just a log.
8270 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8271 even if the time zone offset is outlandishly large.
8272 Don't mishandle offset == INT_MIN.
8274 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8275 when creating daemon; the previous buffer-overflow check was incorrect.
8277 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8278 which has the guts of the old verror function.
8280 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8281 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8283 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8284 (font_unparse_xlfd): Don't blindly alloca long strings.
8285 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8286 fits in int, when using sprintf. Use single snprintf to count
8287 length of string rather than counting it via multiple sprintfs;
8288 that's simpler and more reliable.
8289 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8290 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8291 sprintf, in case result does not fit in int.
8293 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8294 (fontset_from_font): Print it.
8296 * frame.c (tty_frame_count): Now printmax_t, not int.
8297 (make_terminal_frame, set_term_frame_name): Print it.
8298 (x_report_frame_params): In X, window IDs are unsigned long,
8299 not signed long, so print them as unsigned.
8300 (validate_x_resource_name): Check for implausibly long names,
8301 and don't assume name length fits in 'int'.
8302 (x_get_resource_string): Don't blindly alloca invocation name;
8303 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8306 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8307 (xg_check_special_colors, xg_set_geometry):
8308 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8310 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8311 Use esprintf, not sprintf, in case result does not fit in int.
8313 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8314 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8315 it as a large positive number.
8316 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8317 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8319 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8320 in case result does not fit in int.
8322 * print.c (float_to_string): Detect width overflow more reliably.
8323 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8324 buffer overrun. Don't assume list length fits in 'int'. Treat
8325 print length of 0 as 0, not as infinity; to be consistent with other
8326 uses of print length in this function. Don't overflow print length
8327 index. Don't assume hash table size fits in 'long', or that
8328 vectorlike size fits in 'unsigned long'.
8330 * process.c (make_process): Use printmax_t, not int, to format
8331 process-name gensyms.
8333 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8335 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8336 to avoid potential buffer overrun.
8338 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8339 if X resource line is longer than 512 bytes.
8341 * xfns.c (x_window): Make sprintf buffer a bit bigger
8342 to avoid potential buffer overrun.
8344 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8346 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8348 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8350 Integer overflow fixes for scrolling, etc.
8351 Without these, Emacs silently mishandles large integers sometimes.
8352 For example, "C-u 4294967297 M-x recenter" was treated as if
8353 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8355 * xdisp.c (try_window_id): Check Emacs fixnum range before
8356 converting to 'int'.
8358 * window.c (window_scroll_line_based, Frecenter):
8359 Check that an Emacs fixnum is in range before assigning it to 'int'.
8360 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8361 values converted from Emacs fixnums.
8362 (Frecenter): Don't wrap around a line count if it is out of 'int'
8363 range; instead, treat it as an extreme value.
8364 (Fset_window_configuration, compare_window_configurations):
8365 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8367 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8368 that can exceed INT_MAX. Check that EMACS_INT value is in range
8369 before assigning it to the (possibly-narrower) index.
8370 (match_limit): Don't assume that a fixnum can fit in 'int'.
8372 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8375 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8376 (Fvertical_motion): Don't wrap around LINES values that don't fit
8377 in 'int'. Instead, treat them as extreme values. This is good
8378 enough for windows, which can't have more than INT_MAX lines anyway.
8380 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8382 * Require libxml/parser.h to avoid compilation warning.
8384 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8386 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8387 since this reportedly can destroy thread storage.
8389 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8391 * syntax.c (find_defun_start): Update all cache variables if
8392 exiting early (Bug#9401).
8394 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8396 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8398 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8399 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8400 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8402 * term.c (tty_append_glyph): New function.
8403 (produce_stretch_glyph): Static function and its prototype deleted.
8405 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8408 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8410 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8411 when checking :margin (Bug#9390).
8412 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8413 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8414 so that the name doesn't mislead. All uses changed.
8416 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8418 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8421 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8423 * xdisp.c (move_it_to): Don't bail out early when reaching
8424 position beyond to_charpos, if we are scanning backwards.
8425 (move_it_vertically_backward): When DY == 0, make sure we get to
8426 the first character in the line after the newline.
8428 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8430 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8431 (ccl_driver): Do not generate an out-of-range pointer.
8432 (Fccl_execute_on_string): Remove unnecessary check for
8433 integer overflow, noted by Stefan Monnier in
8434 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8435 Remove a FIXME that didn't need fixing.
8436 Simplify the newly-introduced buffer reallocation code.
8438 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8440 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8442 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8444 Integer and memory overflow issues (Bug#9196).
8446 * doc.c (get_doc_string): Rework so that
8447 get_doc_string_buffer_size is the actual buffer size, rather than
8448 being 1 less than the actual buffer size; this makes xpalloc more
8451 * image.c (x_allocate_bitmap_record, cache_image):
8452 * xselect.c (Fx_register_dnd_atom):
8453 Simplify previous changes by using xpalloc.
8455 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8456 since either will do and ptrdiff_t is convenient with xpalloc.
8458 * charset.c (charset_table_size)
8459 (struct charset_sort_data.priority): Now ptrdiff_t.
8460 (charset_compare): Don't overflow if priorities differ greatly.
8461 (Fsort_charsets): Don't assume list length fits in int.
8462 Check for size-calculation overflow when allocating sort data.
8463 (syms_of_charset): Allocate an initial charset table that is
8464 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8466 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8468 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8469 The actual value is always <= INT_MAX, and leaving it unsigned made
8470 overflow checking harder.
8472 * dispextern.h (struct glyph_matrix.rows_allocated)
8473 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8474 with xpalloc. The values are still always <= INT_MAX.
8476 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8478 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8479 (SAFE_NALLOCA): New macro.
8481 * region-cache.c (struct boundary.pos, find_cache_boundary)
8482 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8483 (set_cache_region, invalidate_region_cache)
8484 (revalidate_region_cache, know_region_cache, region_cache_forward)
8485 (region_cache_backward, pp_cache):
8486 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8487 so that ptrdiff_t * can be passed to xpalloc.
8488 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8489 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8490 (pp_cache): Don't assume cache_len fits in int.
8491 * region-cache.h: Adjust extern decls to match.
8493 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8494 EMACS_INT, since either will do, for xpalloc.
8496 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8497 (xnmalloc, xnrealloc, xpalloc): New functions.
8499 * bidi.c (bidi_shelve_header_size): New constant.
8500 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8501 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8503 * bidi.c (bidi_cache_shrink):
8504 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8506 Don't update size of array until after memory allocation succeeds,
8507 because xmalloc/xrealloc may not return.
8508 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8509 now that we have proper integer overflow checking.
8510 (record_overlay_string, overlay_strings): Catch overflows when
8511 calculating size of overlay_str_buf.
8513 * callproc.c (Fcall_process): Check for size overflow when
8514 calculating size of args2.
8515 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8516 Normally we prefer signed values, but sticking with ptrdiff_t would
8517 require adding more-complicated checks.
8519 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8520 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8521 Redo buffer-overflow calculations to avoid integer overflow.
8522 Add a FIXME comment where memory seems to be over-allocated.
8524 * character.c (Fstring): Check for size-calculation overflow.
8526 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8527 unnecessary integer overflow. Check for size overflow.
8528 (encode_coding_object): Don't update size until xmalloc succeeds.
8530 * composite.c (get_composition_id): Check for overflow in glyph
8531 length calculations.
8533 Integer and memory overflow fixes for display code.
8534 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8535 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8536 (scrolling_window): Check for overflow in size calculations.
8537 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8538 Don't assume glyph table len fits in int.
8539 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8540 (row_table_size): Now ptrdiff_t, not int.
8541 (scrolling_window): Avoid overflow in size calculations.
8542 Don't update size until allocation succeeds.
8543 * fns.c (concat): Check for overflow in size calculations.
8544 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8545 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8546 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8548 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8549 (get_doc_string): Check for size calculation overflow.
8550 Don't update size until allocation succeeds.
8551 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8552 EMACS_INT, where ptrdiff_t will do.
8553 (Fsubstitute_command_keys): Check for string overflow.
8555 * editfns.c (set_time_zone_rule): Don't assume environment length
8557 (message_length): Now ptrdiff_t, not int.
8558 (Fmessage_box): Don't update size until allocation succeeds.
8559 Don't assume message length fits in int.
8560 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8562 * emacs.c (main): Do not reallocate argv, since there is a null at
8563 the end that can be overwritten, and this way there's no need to
8564 worry about size-calculation overflow.
8565 (sort_args): Check for size-calculation overflow.
8567 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8569 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8571 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8572 (x_set_scroll_bar_width, x_figure_window_size):
8573 Check for integer overflow.
8574 (x_set_alpha): Do not assume XINT fits in int.
8576 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8577 This is for the members text_lines, text_cols, total_lines, total_cols,
8578 where the system imposes an 'int' limit.
8580 * fringe.c (Fdefine_fringe_bitmap):
8581 Don't update size until alloc works.
8583 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8584 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8586 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8587 Check for size-calculation overflow.
8588 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8589 do, as we prefer signed integers.
8590 (id_to_widget.max_size, id_to_widget.used)
8591 (xg_store_widget_in_map, xg_remove_widget_from_map)
8592 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8593 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8594 Use and return ptrdiff_t, not int.
8595 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8596 * gtkutil.h: Change prototypes to match the above.
8598 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8599 are duplicate now that they've been promoted to lisp.h.
8600 (x_allocate_bitmap_record, x_alloc_image_color)
8601 (make_image_cache, cache_image, xpm_load):
8602 Don't update size until alloc is done.
8603 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8605 Check for size calculation overflow.
8606 (ct_colors_allocated_max): New constant.
8607 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
8610 * keyboard.c (read_char, menu_bar_items, tool_bar_items)

8612 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8613 Use ptrdiff_t, not int, to count maps.
8614 (read_char_minibuf_menu_prompt): Check for overflow in size
8615 calculations. Don't update size until allocation succeeds.
8616 Redo calculations to avoid overflow.
8617 * keyboard.h: Change prototypes to match the above.
8619 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

8626 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
8627 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8629 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8630 Now ptrdiff_t, not int.
8631 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8632 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
8634 * process.c (Fnetwork_interface_list): Check for overflow

8640 overflow. Don't bother calling xmalloc when xrealloc will do.
8642 * search.c (Freplace_match): Check for size calculation overflow.
8643 (Fset_match_data): Don't assume list lengths fit in 'int'.
8645 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8646 for command line length. Do not attempt to address one before the
8647 beginning of an array, as that's not portable.

8650 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8652 (encode_terminal_code, calculate_costs): Check for size
8653 calculation overflow.
8654 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
8655 table lengths and related sizes. Don't update size until alloc
8656 done. Redo calculations to avoid overflow.
8657 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8659 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
8660 subtracting pointers.

8675 Use ptrdiff_t, not int, for sizes.
8676 (Finternal_make_lisp_face, cache_face):
8677 Check for size calculation overflow.
8678 (cache_face): Treat size calculation overflows as if they were
8679 memory exhaustion (the usual treatment), rather than aborting.
8681 * xfns.c (x_encode_text, x_set_name_internal)
8682 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8683 sizes, since they can exceed INT_MAX in size. Check for size
8684 calculation overflow.
8686 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8687 (xg_select): Check for size calculation overflow.
8688 Don't update size until alloc done.
8690 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8691 as sprintf is limited to int lengths.
8693 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8694 (X_LONG_MIN): New macros.
8695 Use them to make the following changes clearer.
8696 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8697 This change doesn't affect the value now, but it may help remind
8698 future maintainers not to raise the value too much later.
8699 (SELECTION_QUANTUM): Remove, replacing with ...
8700 (selection_quantum): ... new function, which avoids overflow.
8702 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8703 assumption that selection length fits in 'int'.
8704 (x_reply_selection_request, x_handle_selection_request)
8705 (x_get_window_property, receive_incremental_selection)

8711 Redo calculations to avoid overflow.
8712 (x_reply_selection_request): When sending hint, ceiling it at
8713 X_LONG_MAX rather than relying on wraparound overflow to send

8716 (lisp_data_to_selection_data, x_property_data_to_lisp):
8717 Check for size-calculation overflow.

8720 Don't store size until memory allocation succeeds.
8721 (x_get_window_property): Plug memory leak on memory exhaustion.
8722 Don't double-block input; malloc is safe here. Don't assume 2**34
8723 - 4 fits in unsigned long. Add an xassert to check
8724 XGetWindowProperty overflow. Be more careful about overflow
8725 calculations, and distinguish size from memory overflow better.
8726 (receive_incremental_selection): When tracing, don't assume
8727 unsigned int is less than INT_MAX.
8728 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8729 harmful) conversions of unsigned short to int.
8730 (lisp_data_to_selection_data): Don't assume that integers
8731 in the range -65535 through -1 fit in an X unsigned short.
8732 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8733 result parameters unless successful. Rely on cons_to_unsigned
8734 to report problems with elements; the old code wasn't right anyway.
8735 (x_check_property_data): Check for int overflow; we cannot use
8736 a wider type due to X limits.
8737 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8739 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
8741 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
8742 (x_term_init): Check for size calculation overflow.
8743 (x_color_cells): Don't store size until memory allocation succeeds.

8769 * lisp.h (hash_lookup, hash_put):
8770 * minibuf.c (Ftest_completion):
8771 Use ptrdiff_t for hash table indexes, not int (which is too
8772 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8773 32-bit --with-wide-int hosts).
8775 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8776 Add a FIXME comment about memory leaks.

8781 * character.h (CHAR_WIDTH):
8782 * indent.c (MULTIBYTE_BYTES_WIDTH):
8783 Use sanitize_char_width to avoid undefined and/or bad behavior
8784 with outlandish widths.
8785 * character.h (sanitize_tab_width): Rename from sanitize_width,
8786 now that we have two such functions. All uses changed.
8787 (sanitize_char_width): New inline function.
8789 Don't assume that tab-width fits in int.

8805 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8806 (x_send_scroll_bar_event): Likewise. Check that the size does not
8807 exceed limits imposed by XClientMessageEvent, as well as the usual
8808 ptrdiff_t and size_t limits.
8810 * keyboard.c: Overflow, signedness and related fixes.
8811 (make_lispy_movement): Use same integer type in forward decl
8812 that is used in the definition.
8813 (read_key_sequence, keyremap_step):
8814 Change bufsize argument back to int, undoing my 2011-03-30 change.
8815 We prefer signed types, and int is wide enough here.
8816 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8817 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8818 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8819 length, not size_t. Use ptrdiff_t for index, not int.
8820 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8821 possibility of integer overflow.

8833 * xdisp.c (calc_pixel_width_or_height):
8834 * xfns.c (image_cache_refcount):
8835 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8836 on typical 64-bit hosts.

8844 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8845 (lookup_image): Remove unnecessary tests.
8846 (xbm_image_p): Locals are now of int, not EMACS_INT,
8847 since parse_image_check makes sure they fit into int.
8848 (png_load, gif_load, svg_load_image):
8849 Prefer int to unsigned where either will do.
8850 (tiff_handler): New function, combining the cores of the
8851 old tiff_error_handler and tiff_warning_handler.
8852 This function is rewritten to use vsnprintf and thereby avoid
8853 stack buffer overflows. It uses only the features of vsnprintf
8854 that are common to both POSIX and native Microsoft.
8855 (tiff_error_handler, tiff_warning_handler): Use it.
8856 (tiff_load, gif_load, imagemagick_load_image):
8857 Don't assume :index value fits in 'int'.
8858 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8859 (imagemagick_load_image): Check that crop parameters fit into
8860 the integer types that MagickCropImage accepts. Don't assume
8861 Vimagemagick_render_type has a nonnegative value. Don't assume
8862 size_t fits in 'long'.
8863 (gs_load): Use printmax_t to print the widest integers possible.

8876 handle_single_display_spec, not just 1 or zero.
8877 (handle_single_display_spec): If the display spec is of the form
8878 `(space ...)', and specifies display in the text area, return 2
8880 (try_cursor_movement): Check for the need to scroll more
8881 accurately, and prefer exact match for point under bidi.
8882 Don't advance `row' beyond the last row of the window.
8884 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8885 into disp_prop; all users changed.
8887 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8903 positioning on the newline at EOL of R2L text within L2R
8904 paragraph, and vice versa.
8905 (try_cursor_movement): Check continued rows, in addition to
8906 continuation rows. Fixes unwarranted scroll when point enters a
8907 continued line of R2L text within an L2R paragraph, or vice versa.
8908 (cursor_row_p): Consider the case of point being equal to
8909 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8910 from the end of a short line to the beginning of a continued line
8911 of R2L text within L2R paragraph.
8912 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

8938 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8939 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8940 candidate is selected by the mouse, and that candidate has a
8941 composed character under the mouse.
8943 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8944 coordinates reported by pos-visible-in-window-p for a composed

8955 composed buffer positions.
8957 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8959 * image.c (gif_load): Don't assume that each subimage has the same
8960 dimensions as the base image. Handle disposal method that is
8961 "undefined" by the gif spec (Bug#9335).
8963 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8965 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8968 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8970 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8971 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8972 from an Org mode buffer to a Speedbar frame.
8974 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8975 a composition, take its buffer position from IT->cmp_it.charpos.
8976 Fixes cursor positioning at the beginning of a line that begins
8977 with a composed character.
8979 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8981 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8982 character bidirectional type, use STRONG_L instead. Fixes crashes
8983 in a buffer produced by `describe-categories'.
8985 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8986 members before the level stack, so they would be saved and
8987 restored when copying iterator state. Fixes incorrect reordering
8988 around TABs covered by display properties.
8990 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8992 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

9078 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9079 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
9080 the event loop (Bug#7276).

9101 * process.c (Fnetwork_interface_info): Declare local only if needed.
9103 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
9105 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
9106 (Fnetwork_interface_list): Allocate in increments of bytes instead
9107 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
9108 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
9110 (struct ifflag_def): notrailers is smart on OSX.
9111 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9112 Get hardware address with getifaddrs if available.
9114 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9116 * xdisp.c (iterate_out_of_display_property): xassert that
9117 IT->position is set to within IT->object's boundaries. Break from
9118 the loop as soon as EOB is reached; avoids infloops in redisplay
9119 when IT->position is set up wrongly due to some bug.
9120 Set IT->current to match the bidi iterator unconditionally.
9121 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9122 entry. Force push_it to save on the stack the current
9123 buffer/string position, to be restored by pop_it. Fix flags in
9124 the iterator structure wrt the object coming from a display
9125 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9126 properties. (Bug#9284)
9128 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9130 * fontset.c (fontset_get_font_group): Add proper type checks.
9133 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9135 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
9136 and LC_VERSION_MIN_MACOSX.
9137 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
9138 (dump_it) [LC_FUNCTION_STARTS]: Use it.
9140 2011-08-08 Eli Zaretskii <eliz@gnu.org>
9142 * xdisp.c (forward_to_next_line_start): Allow to use the
9143 no-display-properties-and-no-overlays under bidi display.
9144 Set disp_pos in the bidi iterator to avoid searches for display
9145 properties and overlays.
9147 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9149 * editfns.c (Fset_time_zone_rule): Document relationship with the
9152 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9153 the font entity extracted from the cache (Bug#8109).
9155 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9157 * composite.c (autocmp_chars): Don't reset point. That is done by
9158 restore_point_unwind (Bug#5984).
9160 2011-08-07 Juri Linkov <juri@jurta.org>
9162 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9163 to show the arg `TIME' instead of `TIMEVAL'.
9165 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9167 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9168 display property strides EOL and includes a newline, as in
9169 longlines-mode. (Bug#9254)
9170 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9171 word-wrap under bidirectional display. (Bug#9224)
9173 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9174 is non-zero, even if the data buffer is NULL. Fixes a crash in
9175 vertical-motion with longlines-mode. (Bug#9254)
9177 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9179 * bidi.c <bidi_cache_total_alloc>: Now static.
9180 (bidi_initialize): Initialize bidi_cache_total_alloc.
9182 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9185 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9186 amount allocated this far in `bidi_cache_total_alloc'.
9187 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9188 non-zero, only free the data buffer without restoring the cache
9189 contents. All callers changed.
9191 * dispextern.h (bidi_unshelve_cache): Update prototype.
9193 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9194 (move_it_in_display_line, move_it_to)
9195 (move_it_vertically_backward, move_it_by_lines): Replace the call
9196 to xfree to an equivalent call to bidi_unshelve_cache.
9197 (move_it_in_display_line_to): Fix logic of returning
9198 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9200 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9202 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9203 came from a string character with a `cursor' property. (Bug#9229)
9205 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9207 * Makefile.in (LIB_PTHREAD): New variable.
9208 (LIBES): Add LIB_PTHREAD (Bug#9216).
9210 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9211 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9213 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9215 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9217 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9219 * xterm.c (x_find_topmost_parent): New function.
9220 (x_set_frame_alpha): Find topmost parent window with
9221 x_find_topmost_parent and set the property there also (bug#9181).
9222 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9224 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9226 * callproc.c (Fcall_process): Avoid vfork clobbering
9227 the local vars buffer, coding_systems, current_dir.
9229 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9231 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9233 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9235 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9236 so that it is not optimized away.
9238 * xdisp.c (compute_display_string_pos): Remove unused local.
9240 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9242 Fix slow cursor motion and scrolling in large buffers with
9243 selective display, like Org Mode buffers. (Bug#9218)
9245 * dispextern.h (struct bidi_it): New member disp_prop_p.
9247 * xdisp.c: Remove one-slot cache of display string positions.
9248 (compute_display_string_pos): Accept an additional argument
9249 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9250 for a display string or property. If found, set DISP_PROP_P
9253 * bidi.c (bidi_fetch_char): Accept an additional argument
9254 DISP_PROP_P, and pass it to compute_display_string_pos.
9255 Only handle text covered by a display string if DISP_PROP_P is returned
9256 non-zero. All callers of bidi_fetch_char changed.
9258 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9260 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9262 2010-12-03 Don March <don@ohspite.net>
9264 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9265 last character M-[char] is translated to ESC [char] (bug#7541).
9267 2011-08-02 Kenichi Handa <handa@m17n.org>
9269 * lisp.h (uniprop_table): Extern it.
9271 * chartab.c (uniprop_table): Make it non-static.
9273 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9275 * xdisp.c (forward_to_next_line_start): Accept additional argument
9276 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9278 (reseat_at_next_visible_line_start): Use the bidi iterator state
9279 returned by forward_to_next_line_start to restore the state of
9280 it->bidi_it after backing up to previous newline. (Bug#9212)
9282 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9284 * regex.c (re_comp): Protoize.
9285 (re_exec): Fix return type.
9286 (regexec): Fix type of `ret'. (Bug#9203)
9288 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9290 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9291 This is needed if max-image-size is a floating-point number.
9293 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9295 * print.c (print_object): Print empty symbol as ##.
9297 * lread.c (read1): Read ## as empty symbol.
9299 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9301 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9302 setting frame foreground color (Bug#9175).
9303 (x_set_background_color): Likewise.
9305 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9306 contents (Bug#9176).
9307 (EmacsTooltip -init): Remove bezels and add shadows to
9310 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9311 or scroll bar (Bug#8470).
9313 * nsfont.m (nsfont_open): Remove assignment to voffset and
9314 unnecessary vars hshink, expand, hd, full_height, min_height.
9315 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9317 * nsterm.h (nsfont_info): Remove voffset field.
9319 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9321 Implement strike-through and overline on NextStep (Bug#8863).
9323 * nsfont.m (nsfont_open): Use underline position provided by font,
9324 instead of hard-coded value of 2.
9325 (nsfont_draw): Call ns_draw_text_decoration instead.
9327 * nsterm.h: Add declaration for ns_draw_text_decoration.
9329 * nsterm.m (ns_draw_text_decoration): New function for drawing
9330 underline, overline, and strike-through.
9331 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9332 ns_draw_text_decoration. Change treatment of cursor drawing to
9333 accommodate underlining, etc.
9335 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9337 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9340 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9342 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9343 Without this fix, if a signal arrives just after memory fills up,
9344 'malloc' might be invoked reentrantly.
9346 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9347 In other words, assume that every image size is allowed, on non-X
9348 hosts. This assumption is probably wrong, but it lets Emacs compile.
9350 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9352 * regex.c (re_iswctype): Convert return values to boolean.
9354 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9356 * xdisp.c (compute_display_string_pos): Don't use cached display
9357 string position if the buffer had its restriction changed.
9360 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9362 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9364 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9366 Integer signedness and overflow and related fixes. (Bug#9079)
9368 * bidi.c: Integer size and overflow fixes.
9369 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9370 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9371 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9372 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9373 (bidi_find_other_level_edge):
9374 Use ptrdiff_t instead of EMACS_INT where either will do.
9375 This works better on 32-bit hosts configured --with-wide-int.
9376 (bidi_cache_ensure_space): Check for size-calculation overflow.
9377 Use % rather than repeated addition, for better worst-case speed.
9378 Don't set bidi_cache_size until after xrealloc returns, because it
9380 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9381 (bidi_cache_ensure_space): Also check that the bidi cache size
9382 does not exceed that of the largest Lisp string or buffer. See Eli
9383 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9385 * alloc.c (__malloc_size_t): Remove.
9386 All uses replaced by size_t. See Andreas Schwab's note
9387 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9389 * image.c: Improve checking for integer overflow.
9390 (check_image_size): Assume that f is nonnull, since
9391 it is always nonnull in practice. This is one less thing to
9392 worry about when checking for integer overflow later.
9393 (x_check_image_size): New function, which checks for integer
9394 overflow issues inside X.
9395 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9396 This removes the need for a memory_full check.
9397 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9398 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9399 (xbm_read_bitmap_data): Change locals back to 'int', since
9400 their values must fit in 'int'.
9401 (xpm_load_image, png_load, tiff_load):
9402 Invoke x_create_x_image_and_pixmap earlier,
9403 to avoid much needless work if the image is too large.
9404 (tiff_load): Treat overly large images as if
9405 x_create_x_image_and_pixmap failed, not as malloc failures.
9406 (gs_load): Use x_check_image_size.
9408 * gtkutil.c: Omit integer casts.
9409 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9410 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9412 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9414 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9415 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9416 would wrongly return t on a 64-bit host.
9418 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9419 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9420 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9421 and therefore cause GCC to emit a bogus diagnostic in some cases.
9423 * image.c: Integer signedness and overflow and related fixes.
9424 This is not an exhaustive set of fixes, but it's time to
9425 record what I've got.
9426 (lookup_pixel_color, check_image_size): Remove redundant decls.
9427 (check_image_size): Don't assume that arbitrary EMACS_INT values
9428 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9429 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9430 (tiff_load, imagemagick_load_image):
9431 Check for overflow in size calculations.
9432 (x_create_x_image_and_pixmap): Remove unnecessary test for
9433 xmalloc returning NULL; that can't happen.
9434 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9435 (xpm_color_bucket): Use better integer hashing function.
9436 (xpm_cache_color): Don't possibly over-allocate memory.
9437 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9438 (gif_memory_source):
9439 Use ptrdiff_t, not int or size_t, to record sizes.
9440 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9441 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9442 either works, as we prefer signed integers.
9443 (tiff_read_from_memory, tiff_write_from_memory):
9444 Return tsize_t, not size_t, since that's what the TIFF API wants.
9445 (tiff_read_from_memory): Don't fail simply because the read would
9446 go past EOF; instead, return a short read.
9447 (tiff_load): Omit no-longer-needed casts.
9448 (Fimagemagick_types): Don't assume size fits into 'int'.
9450 Improve hashing quality when configured --with-wide-int.
9451 * fns.c (hash_string): New function, taken from sxhash_string.
9452 Do not discard information about ASCII character case; this
9453 discarding is no longer needed.
9454 (sxhash-string): Use it. Change sig to match it. Caller changed.
9455 * lisp.h: Declare it.
9456 * lread.c (hash_string): Remove, since we now use fns.c's version.
9457 The fns.c version returns a wider integer if --with-wide-int is
9458 specified, so this should help the quality of the hashing a bit.
9460 * emacs.c: Integer overflow minor fix.
9461 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9462 Define only if GNU_LINUX.
9463 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9465 * dispnew.c: Integer signedness and overflow fixes.
9466 Remove unnecessary forward decls, that were a maintenance hassle.
9467 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9469 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9470 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9471 (prepare_desired_row, line_draw_cost):
9472 Use int, not unsigned, where either works.
9473 (save_current_matrix, restore_current_matrix):
9474 Use ptrdiff_t, not size_t, where either works.
9475 (init_display): Check for overflow more accurately, and without
9476 relying on undefined behavior.
9478 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9479 Remove, replacing with the new symbols in lisp.h. All uses changed.
9480 * fileio.c (make_temp_name):
9481 * filelock.c (lock_file_1, lock_file):
9482 * xdisp.c (message_dolog):
9483 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9484 Use pMd etc. instead.
9485 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9486 replacing the pWIDE etc. symbols removed from editfns.c.
9488 * keyboard.h (num_input_events): Now uintmax_t.
9489 This is (very slightly) less likely to mess up due to wraparound.
9492 * buffer.c: Integer signedness fixes.
9493 (alloc_buffer_text, enlarge_buffer_text):
9494 Use ptrdiff_t rather than size_t when either will do, as we prefer
9497 * alloc.c: Integer signedness and overflow fixes.
9498 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9499 (__malloc_size_t): Default to size_t, not to int.
9500 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9501 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9502 Prefer ptrdiff_t to size_t when either would do, as we prefer
9504 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9505 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9506 Now const. Initialize with values that are in range even if char
9508 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9509 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9510 These functions do the right thing with sizes > 2**32.
9511 (check_depth): Now ptrdiff_t, not int.
9512 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9513 Adjust to new way of storing sizes. Check for size overflow bugs
9515 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9516 slightly wrong anyway, as it missed one instance of
9517 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9518 (refill_memory_reserve): Omit needless cast to size_t.
9519 (mark_object_loop_halt): Mark as externally visible.
9521 * xselect.c: Integer signedness and overflow fixes.
9522 (Fx_register_dnd_atom, x_handle_dnd_message):
9523 Use ptrdiff_t, not size_t, since we prefer signed.
9524 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9525 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9526 x_dnd_atoms_size and x_dnd_atoms_length.
9528 * doprnt.c: Prefer signed to unsigned when either works.
9530 * doprnt.c (doprnt):
9532 * xdisp.c (vmessage):
9533 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9534 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9535 prefer signed arithmetic to avoid comparison confusion.
9536 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9537 but is a bit tricky.
9539 Assume freestanding C89 headers, string.h, stdlib.h.
9540 * data.c, doprnt.c, floatfns.c, print.c:
9541 Include float.h unconditionally.
9542 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9543 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9544 * regex.c: Likewise for stddef.h, string.h.
9545 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9546 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9547 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9548 (STDC_HEADERS): Remove obsolete defines.
9549 * sysdep.c: Include limits.h unconditionally.
9551 Assume support for memcmp, memcpy, memmove, memset.
9552 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9553 * regex.c (memcmp, memcpy):
9554 Remove; we assume C89 now.
9556 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9557 (__malloc_safe_bcopy): Remove; no longer needed.
9559 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9560 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9561 well either way, and we prefer signed to unsigned.
9563 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9565 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9566 closes the connection while we're reading (bug#9182).
9568 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9570 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9571 are specified (Bug#9168).
9573 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9575 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9576 Found by GCC static checking and --with-wide-int on a 32-bit host.
9578 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9580 * xdisp.c (compute_display_string_pos): Fix logic of caching
9581 previous display string position. Initialize cached_prev_pos to
9582 -1. Fixes slow-down at the beginning of a buffer.
9584 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9586 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9587 for attrs[LFACE_FONTSET_INDEX].
9589 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9591 * xml.c (parse_region): Remove unused local
9592 that was recently introduced.
9594 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9596 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9597 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9599 * xdisp.c (move_it_in_display_line_to): Record the best matching
9600 position for TO_CHARPOS while scanning the line, and restore it on
9601 exit if none of the characters scanned was an exact match.
9602 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9603 when exact match is impossible due to invisible text, and the
9604 lines are truncated.
9606 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9608 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9611 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9613 Fix a significant slow-down of cursor motion with C-n, C-p,
9614 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9615 auto-repeat under bidi redisplay in fontified buffers.
9616 * xdisp.c (compute_stop_pos_backwards): New function.
9617 (next_element_from_buffer): Call compute_stop_pos_backwards to
9618 find a suitable prev_stop when we find ourselves before
9620 (reseat): Don't look for prev_stop, as that could mean a very long
9622 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9623 <cached_disp_overlay_modiff>: Cache for last found display string
9625 (compute_display_string_pos): Return the cached position if asked
9626 about the same buffer in the same area of character positions, and
9627 the buffer wasn't changed since the time the display string
9628 position was cached.
9630 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9632 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9633 is an integer, which is important for empty lines. (Bug#9149)
9635 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9637 * frame.c (Fmodify_frame_parameters): In tty case, update the
9638 default face if necessary (Bug#4238).
9640 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9642 * editfns.c (Fstring_to_char): No need to explain what a character
9643 is in the docstring (Bug#6576).
9645 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9647 * xml.c (parse_region): Make sure we always return a tree.
9649 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9651 * xml.c (parse_region): If a document contains only comments,
9654 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9656 * xml.c (make_dom): Return comments, too.
9658 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9661 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9662 and the surrounding thread.
9663 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9664 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9665 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9667 * s/openbsd.h (BROKEN_SIGIO): Define.
9668 * unexelf.c (unexec) [__OpenBSD__]:
9669 Don't update the .mdebug section of the Alpha COFF symbol table.
9671 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9673 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9676 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9678 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9679 This fixes some race conditions on the permissions of any newly
9682 * alloc.c (valid_pointer_p): Use pipe, not open.
9683 This fixes some permissions issues when debugging.
9685 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9686 If fchown fails to set both uid and gid, try to set just gid,
9687 as that is sometimes allowed. Adjust the file's mode to eliminate
9688 setuid or setgid bits that are inappropriate if fchown fails.
9690 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9692 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9693 to compare Lisp_Objects.
9694 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to

9704 symbol character follows.
9706 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9708 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9709 This works around a problem with the previous change to Fcopy_file.
9710 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9711 and without this change, GCC might complain about discarding
9712 fchown's return value.
9714 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9716 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9718 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9720 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9722 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9724 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9725 it's used from the C level.
9727 * process.c: Use the same condition for POLL_FOR_INPUT in both
9728 keyboard.c and process.c (bug#1858).
9730 2011-07-09 Lawrence Mitchell <wence@gmx.li>

9737 * doc.c (Fsubstitute_command_keys): Revert last change.
9739 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9741 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9742 quotes the next character, and doesn't affect other longer
9743 sequences (bug#8935).
9745 * lread.c (syms_of_lread): Clarify that is isn't only
9746 `eval-buffer' and `eval-defun' that's affected by
9747 `lexical-binding' (bug#8460).
9749 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9751 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9752 bidi redisplay when a line includes both an image and is truncated.
9754 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9756 Fix minor problems found by static checking.
9757 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9758 (elsz): Now a signed constant, not a size_t var. We prefer signed
9759 types to unsigned, to avoid integer comparison confusion. Without
9760 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9761 "cannot optimize loop, the loop counter may overflow", a symptom
9763 * indent.c (Fvertical_motion): Mark locals as initialized.
9764 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9766 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9768 * search.c (Fre_search_backward): Mention `case-fold-search' in
9769 all the re_search_* functions (bug#8138).

9787 Initialize itb.string.lstring.
9788 (init_iterator): Call bidi_init_it only of a valid
9789 buffer position was specified. Initialize paragraph_embedding to
9791 (reseat_to_string): Initialize the bidi iterator.
9792 (display_string): If we need to ignore text properties of
9793 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9794 original value of -1 will not work with bidi.)

9798 (compute_display_string_end): Support display properties on Lisp
9800 (init_iterator, reseat_1, reseat_to_string): Initialize the
9801 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9802 when iterating on a string not from display properties).
9803 (compute_display_string_pos, compute_display_string_end):
9804 Fix calculation of the object to scan. Fixes an error when using
9806 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9807 base_level_stop; instead, set base_level_stop to BEGV.
9808 Fixes crashes in vertical-motion.
9809 (next_element_from_buffer): Improve commentary for when
9810 the iterator is before prev_stop.
9811 (init_iterator): Initialize bidi_p from the default value of
9812 bidi-display-reordering, not from buffer-local value. Use the
9813 buffer-local value only if initializing for buffer iteration.
9814 (handle_invisible_prop): Support invisible properties on strings
9815 that are being bidi-reordered.
9816 (set_iterator_to_next): Support bidi reordering of C strings and

9833 (get_visually_first_element): New function, refactored from common
9834 parts of next_element_from_buffer, next_element_from_string, and
9835 next_element_from_c_string.
9836 (tool_bar_lines_needed, redisplay_tool_bar)
9837 (display_menu_bar): Force left-to-right direction. Add a FIXME
9838 comment for making that be controlled by a user option.

9848 iterator for displaying display or overlay strings.
9849 (forward_to_next_line_start): Don't use the shortcut if
9851 (back_to_previous_visible_line_start): If handle_display_prop
9852 pushed the iterator stack, restore the internal state of the bidi
9853 iterator by calling bidi_pop_it same number of times.
9854 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9855 and we are bidi-iterating, don't decrement the iterator position;
9856 instead, set the first_elt flag in the bidi iterator, to produce
9858 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9859 (push_display_prop): xassert that we are iterating a buffer.
9860 (push_it, pop_it): Save and restore paragraph_embedding member.
9861 (handle_single_display_spec, next_overlay_string)

9864 correctly. Don't assume unibyte strings are not bidi-reordered.
9865 (compute_display_string_pos)
9866 (compute_display_string_end): Fix handling the case of C string.
9867 (push_it, pop_it): Save and restore from_disp_prop_p.
9868 (handle_single_display_spec, push_display_prop): Set the
9869 from_disp_prop_p flag.
9870 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9917 (bidi_move_to_visually_next): Compare cache index with
9918 bidi_cache_start rather than with zero.
9919 (bidi_fetch_char): Accept new argument STRING; all callers
9920 changed. Support iteration over a string. Support strings with
9921 display properties. Support unibyte strings. Fix the type of
9922 `len' according to what STRING_CHAR_AND_LENGTH expects.
9923 (bidi_paragraph_init, bidi_resolve_explicit_1)

10018 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
10020 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
10021 The old code sometimes used this field without initializing it.
10023 * alloc.c (gc_sweep): Don't read past end of array.
10024 In theory, the old code could also have corrupted Emacs internals,
10025 though it'd be very unlikely.

10292 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

10330 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10331 subseconds part to the entropy, as that's a bit more random.
10332 Prefer signed to unsigned, since the signedness doesn't matter and
10333 in general we prefer signed. When given a limit, use a
10334 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10335 latter isn't right if USE_2_TAGS_FOR_INTS.
10336 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10337 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10349 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
10350 This is more efficient than Ffile_directory_p and avoids a minor race.

10354 * buffer.c (Foverlay_put): Say what the return value is
10357 * fileio.c (barf_or_query_if_file_exists): Check first if the file

10361 error be more correct.
10363 * fns.c (Frequire): Remove the mention of the .gz files, since

10380 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
10381 Also (re)move comments that are misplaced or no longer relevant.

10410 * lread.c (syms_of_lread): Mention single symbols defined by

10467 with value as argument.
10468 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
10469 g_settings_new (Bug#8967). Do not create gsettings_obj.

10480 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
10482 * eval.c (struct backtrace): Simplify and port the data structure.
10483 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10484 signed bit field, as this assumption is not portable and it makes
10485 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10486 "char debug_on_exit : 1" as this is not portable either; instead,
10487 use the portable "unsigned int debug_on_exit : 1". Remove unused
10488 member evalargs. Remove obsolete comments about cc bombing out.
10490 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

10558 (emacs_fixed_new): Set priv->f to argument.
10559 (emacs_fixed_get_preferred_width)
10560 (emacs_fixed_get_preferred_height): Use min_width/height from
10561 frames size_hint to set minimum and natural (Bug#8919).
10562 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
10563 and use min_width/height from frames size_hint to set
10564 min_width/height (Bug#8919).

10584 Use gnulib's dup2 module instead of rolling our own.
10585 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
10587 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10589 * dispnew.c (scrolling_window): Before scrolling, turn off a

10652 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10654 Integer and buffer overflow fixes (Bug#8873).
10656 * print.c (printchar, strout): Check for string overflow.
10657 (PRINTPREPARE, printchar, strout):
10658 Don't set size unless allocation succeeds.
10660 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10661 for sizes. Check for string overflow more accurately.
10662 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10664 * macros.c: Integer and buffer overflow fixes.
10665 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10666 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10667 Use ptrdiff_t, not int, for sizes.

10669 Check for size-calculation overflow.
10670 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10672 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10674 * lread.c: Integer overflow fixes.
10675 (read_integer): Radix is now EMACS_INT, not int,
10676 to improve quality of diagnostics for out-of-range radices.
10677 Calculate buffer size correctly for out-of-range radices.
10678 (read1): Check for integer overflow in radices, and in
10679 read-circle numbers.
10680 (read_escape): Avoid int overflow.
10681 (Fload, openp, read_buffer_size, read1)
10682 (substitute_object_recurse, read_vector, read_list, map_obarray):
10683 Use ptrdiff_t, not int, for sizes.

10698 2011-06-22 Leo Liu <sdl.web@gmail.com>
10700 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10701 Move to minibuffer.el.
10703 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10705 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10706 The following patches are for when GLYPH_DEBUG && !XASSERT.
10707 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10708 * dispnew.c (flush_stdout):
10709 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10710 Mark as externally visible.
10711 * dispnew.c (check_window_matrix_pointers): Now static.
10712 * dispnew.c (window_to_frame_vpos):
10713 * xfns.c (unwind_create_frame):
10714 * xterm.c (x_check_font): Remove unused local.
10715 * scroll.c (CHECK_BOUNDS):
10716 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10717 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10718 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10719 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10720 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10722 (debug_method_add): Use va_list and vsprintf rather than relying
10723 on undefined behavior with wrong number of arguments.
10724 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10725 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10726 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10727 since we're not interested in debugging glyphs with old libraries.
10728 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10729 GCC 4.6.0's static checking.
10731 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10733 Integer overflow and signedness fixes (Bug#8873).

10742 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10743 (x_create_bitmap_from_xpm_data):
10744 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10745 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10747 * xfaces.c (load_pixmap):
10748 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10749 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10750 (.bitmaps_last, struct x_output.icon_bitmap):
10751 Use ptrdiff_t, not int, for bitmap indexes.
10752 (x_allocate_bitmap_record): Check for size overflow.
10753 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10755 Use ptrdiff_t, not int, for overlay counts.
10756 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10757 * editfns.c (overlays_around, get_pos_property):
10758 * textprop.c (get_char_property_and_overlay):
10759 * xdisp.c (next_overlay_change, note_mouse_highlight):
10760 * xfaces.c (face_at_buffer_position):
10761 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10762 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10763 (Fnext_overlay_change, Fprevious_overlay_change)
10764 (mouse_face_overlay_overlaps, Foverlays_in):
10765 Use ptrdiff_t, not int, for sizes.
10766 (overlays_at, overlays_in): Check for size-calculation overflow.
10768 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10770 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10771 (x_session_initialize): Do not assume string length fits in int.
10773 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10774 This is unlikely, but can occur if DPI is outlandish.
10776 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10777 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10779 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10780 * xrdb.c (magic_file_p, search_magic_path):
10781 Omit last arg SUFFIX; it was always 0. All callers changed.
10782 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10784 * xfont.c (xfont_match): Avoid need for strlen.
10786 * xfns.c: Don't assume strlen fits in int.
10787 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10789 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10790 not unsigned long, as we prefer signed integers. All callers changed.
10791 Detect integer overflow in repeat count.
10792 (message_dolog): Don't assume print length fits in 39 bytes.
10793 (display_mode_element): Don't assume strlen fits in int.
10795 * termcap.c: Don't assume sizes fit in int and never overflow.
10796 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10797 (gobble_line): Check for size-calculation overflow.
10799 * minibuf.c (Fread_buffer):
10800 * lread.c (intern, intern_c_string):
10801 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10802 Don't assume string length fits in int.
10804 * keyboard.c (parse_tool_bar_item):
10805 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10807 * font.c: Don't assume string length fits in int.
10808 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):

10811 Don't assume integer property fits in fixnum.
10812 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10814 * filelock.c: Fix some buffer overrun and integer overflow issues.
10815 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10816 Reformulate so as not to need the command string.
10817 Invoke gzip -cd rather than gunzip, as it's more portable.
10818 (lock_info_type, lock_file_1, lock_file):
10819 Don't assume pid_t and time_t fit in unsigned long.
10820 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10821 (current_lock_owner): Prefer signed type for sizes.
10822 Use memcpy, not strncpy, where memcpy is what is really wanted.
10823 Don't assume (via atoi) that time_t and pid_t fit in int.
10824 Check for time_t and/or pid_t out of range, e.g., via a network share.
10825 Don't alloca where an auto var works fine.
10827 * fileio.c: Fix some integer overflow issues.
10828 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10829 Don't assume string length fits in int.
10830 (directory_file_name): Don't assume string length fits in long.
10831 (make_temp_name): Don't assume pid fits in int, or that its print
10832 length is less than 20.
10834 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10836 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10838 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10840 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10841 We prefer signed integers, even for size calculations.
10843 * emacs.c: Don't assume string length fits in 'int'.
10844 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10845 (main): Don't invoke strlen when not needed.
10847 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

10850 * callproc.c (getenv_internal_1, getenv_internal)
10851 (Fgetenv_internal):
10852 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10854 * lread.c (invalid_syntax): Omit length argument.
10855 All uses changed. This doesn't fix a bug, but it simplifies the
10856 code away from its former Hollerith-constant appearance, and it's
10857 one less 'int' to worry about when looking at integer-overflow issues.
10858 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10860 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10861 This didn't break anything, but it didn't help either.
10862 It's confusing to put a bogus integer in a place where the actual
10863 value does not matter.
10864 (LIST_END_P): Remove unused macro and its bogus comment.
10865 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10867 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10868 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10870 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10871 We prefer signed types, and the value cannot exceed the EMACS_INT
10872 range anyway (because otherwise the length would not be representable).
10873 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10874 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10875 This avoids a GCC warning when WIDE_EMACS_INT.
10877 * indent.c (sane_tab_width): New function.
10878 (current_column, scan_for_column, Findent_to, position_indentation)
10879 (compute_motion): Use it. This is just for clarity.
10880 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10882 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10884 * lisp.h (lint_assume): New macro.
10885 * composite.c (composition_gstring_put_cache):
10886 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10888 * editfns.c, insdel.c:
10889 Omit unnecessary forward decls, to simplify future changes.
10891 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10893 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10895 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10896 Use much-faster test for byte-length change.
10897 Don't assume string byte-length fits in 'int'.
10898 Check that character arg fits in 'int'.
10899 (mapcar1): Declare byte as byte, for clarity.
10901 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10903 * fns.c (concat): Catch string overflow earlier.
10904 Do not rely on integer wraparound.
10906 * dispextern.h (struct it.overlay_strings_charpos)
10907 (struct it.selective): Now EMACS_INT, not int.
10908 * xdisp.c (forward_to_next_line_start)
10909 (back_to_previous_visible_line_start)
10910 (reseat_at_next_visible_line_start, next_element_from_buffer):
10911 Don't arbitrarily truncate the value of 'selective' to int.
10913 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10915 * composite.c: Don't truncate sizes to 'int'.
10916 (composition_gstring_p, composition_reseat_it)
10917 (composition_adjust_point): Use EMACS_INT, not int.
10918 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10919 not EMACS_UINT, for indexes.
10921 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10923 * buffer.c: Include <verify.h>.
10924 (struct sortvec.priority, struct sortstr.priority):
10925 Now EMACS_INT, not int.
10926 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10927 (struct sortstr.size, record_overlay_string)
10928 (struct sortstrlist.size, struct sortlist.used):
10929 Don't truncate size to int.
10930 (record_overlay_string): Check for size-calculation overflow.
10931 (init_buffer_once): Check at compile-time, not run-time.
10933 2011-06-22 Jim Meyering <meyering@redhat.com>
10935 Don't leak an XBM-image-sized buffer
10936 * image.c (xbm_load): Free the image buffer after using it.
10938 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10941 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10942 that Sun C diagnosed.
10943 * fns.c (secure_hash): Fix pointer signedness issue.
10944 * intervals.c (static_offset_intervals): New function.
10945 (offset_intervals): Use it.
10947 2011-06-21 Leo Liu <sdl.web@gmail.com>
10950 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10953 * fns.c (secure_hash): Rename from crypto_hash_function and change
10954 the first arg to accept symbols.
10955 (Fsecure_hash): New primitive.
10956 (syms_of_fns): New symbols.
10958 2011-06-20 Deniz Dogan <deniz@dogan.se>
10960 * process.c (Fset_process_buffer): Clarify return value in
10963 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10965 * dispnew.c (add_window_display_history): Use BVAR.
10967 * xdisp.c (debug_method_add): Use BVAR.
10968 (check_window_end, dump_glyph_matrix, dump_glyph)
10969 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10971 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10974 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10975 check till after the cache is created in init_frame_faces.
10977 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10979 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10981 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10983 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10984 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10985 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10987 Improve buffer-overflow checking (Bug#8873).
10988 * fileio.c (Finsert_file_contents):
10989 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10990 Remove the old (too-loose) buffer overflow checks.
10991 They weren't needed, since make_gap checks for buffer overflow.
10992 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10993 The old code merely checked for Emacs fixnum overflow, and relied
10994 on undefined (wraparound) behavior. The new code avoids undefined
10995 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10997 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10998 Tune. Don't use wider integers than needed. Don't use alloca.
10999 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
11001 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
11003 * insdel.c, lisp.h (buffer_overflow): New function.
11004 (insert_from_buffer_1, replace_range, replace_range_2):
11005 * insdel.c (make_gap_larger):
11006 * editfns.c (Finsert_char):
11007 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
11009 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
11011 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
11013 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
11015 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
11016 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
11018 * fileio.c: Don't assume EMACS_INT fits in off_t.
11019 (emacs_lseek): New static function.
11020 (Finsert_file_contents, Fwrite_region): Use it.
11021 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
11023 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
11025 * fns.c: Don't overflow int when computing a list length.
11026 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
11027 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
11028 truncation on 64-bit hosts. Check for QUIT every
11029 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
11030 faster and is responsive enough.
11031 (Flength): Report an error instead of overflowing an integer.
11032 (Fsafe_length): Return a float if the value is not representable
11033 as a fixnum. This shouldn't happen except in contrived situations.
11034 (Fnthcdr, Fsort): Don't assume list length fits in int.
11035 (Fcopy_sequence): Don't assume vector length fits in int.
11037 * alloc.c: Check that resized vectors' lengths fit in fixnums.
11038 (header_size, word_size): New constants.
11039 (allocate_vectorlike): Don't check size overflow here.
11040 (allocate_vector): Check it here instead, since this is the only
11041 caller of allocate_vectorlike that could cause overflow.
11042 Check that the new vector's length is representable as a fixnum.
11044 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11045 The previous code was bogus. For example, next_almost_prime (32)
11046 returned 39, which is undesirable as it is a multiple of 3; and
11047 next_almost_prime (24) returned 25, which is a multiple of 5 so
11048 why was the code bothering to check for multiples of 7?
11050 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11052 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11054 Variadic C functions now count arguments with ptrdiff_t.
11055 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11056 Back then I didn't know that the Emacs coding style prefers signed int.
11057 Also, in the meantime I found a few more instances where arguments
11058 were being counted with int, which may truncate counts on 64-bit
11059 machines, or EMACS_INT, which may be unnecessarily wide.
11060 * lisp.h (struct Lisp_Subr.function.aMANY)
11061 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11062 Arg counts are now ptrdiff_t, not size_t.
11063 All variadic functions and their callers changed accordingly.
11064 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11065 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11066 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11067 * callint.c (Fcall_interactively): Check arg count for overflow,
11068 to avoid potential buffer overrun. Use signed char, not 'int',
11069 for 'varies' array, so that we needn't bother to check its size
11070 calculation for overflow.
11071 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11072 * eval.c (apply_lambda):
11073 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11074 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11075 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11077 * callint.c (Fcall_interactively): Don't use index var as event count.
11079 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11080 * mem-limits.h (SIZE): Remove; no longer used.
11082 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11084 Remove unnecessary casts.
11085 * xterm.c (x_term_init):
11086 * xfns.c (x_set_border_pixel):
11087 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11088 These aren't needed now that we assume ANSI C.
11090 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11091 It's more likely to cause problems (due to unsigned overflow)
11094 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11096 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11098 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11100 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11102 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11104 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11106 GLYPH_CODE_FACE returns EMACS_INT, not int.
11107 * dispextern.h (merge_faces):
11108 * xfaces.c (merge_faces):
11109 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11110 Don't assume EMACS_INT fits in int.
11112 * character.h (CHAR_VALID_P): Remove unused parameter.
11113 * fontset.c, lisp.h, xdisp.c: All uses changed.
11115 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11117 * fns.c (concat): Minor tuning based on overflow analysis.
11118 This doesn't fix any bugs. Use int to hold character, instead
11119 of constantly refetching from Emacs object. Use XFASTINT, not
11120 XINT, for value known to be a character. Don't bother comparing
11121 a single byte to 0400, as it's always less.
11123 * floatfns.c (Fexpt):
11124 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11126 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11129 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11131 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11132 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11133 incorrectly succeed when S was a string, because 4294967386 was
11134 truncated before it was used.
11136 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11137 Otherwise, an out-of-range integer could cause undefined behavior
11140 * composite.c: Use int, not EMACS_INT, for characters.
11141 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11142 EMACS_INT, for values that are known to be in character range.
11143 This doesn't fix any bugs but is the usual style inside Emacs and
11144 may generate better code on 32-bit machines.
11146 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11147 This is for reasons similar to the recent CHAR_STRING fix.
11148 * charset.c (Fencode_char): Check that character arg is actually
11149 a character. Pass an int to ENCODE_CHAR.
11150 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11151 wider than 'int', as a compile-time check to prevent future regressions
11154 * character.c (char_string): Remove unnecessary casts.
11156 Make sure a 64-bit char is never passed to CHAR_STRING.
11157 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11158 by silently ignoring the top 32 bits, allowing some values
11159 that were far too large to be valid characters.
11160 * character.h: Include <verify.h>.
11161 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11162 arguments are no wider than unsigned, as a compile-time check
11163 to prevent future regressions in this area.
11165 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11166 (Fsubst_char_in_region):
11168 * xdisp.c (decode_mode_spec_coding):
11169 Adjust to CHAR_STRING's new requirement.
11170 * editfns.c (Finsert_char, Fsubst_char_in_region):
11171 * fns.c (concat): Check that character args are actually
11172 characters. Without this test, these functions did the wrong
11173 thing with wildly out-of-range values on 64-bit hosts.
11175 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11176 These casts should not be needed on 32-bit hosts, either.
11177 * keyboard.c (read_char):
11178 * lread.c (Fload): Remove casts to unsigned.
11180 * lisp.h (UNSIGNED_CMP): New macro.
11181 This fixes comparison bugs on 64-bit hosts.
11182 (ASCII_CHAR_P): Use it.
11183 * casefiddle.c (casify_object):
11184 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11185 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11186 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11187 * dispextern.h (FACE_FROM_ID):
11188 * keyboard.c (read_char): Use UNSIGNED_CMP.
11190 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11191 not to EMACS_INT, to avoid GCC warning.
11193 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11195 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11196 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11197 isn't needed on 32-bit machines.
11199 * buffer.c (Fgenerate_new_buffer_name):
11200 Use EMACS_INT for count, not int.
11201 (advance_to_char_boundary): Return EMACS_INT, not int.
11203 * data.c (Qcompiled_function): Now static.
11205 * window.c (window_body_lines): Now static.
11207 * image.c (gif_load): Rename local to avoid shadowing.
11209 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11210 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11211 * alloc.c (make_save_value): Integer argument is now of type
11212 ptrdiff_t, not int.
11213 (mark_object): Use ptrdiff_t, not int.
11214 * lisp.h (pD): New macro.
11215 * print.c (print_object): Use it.
11217 * alloc.c: Use EMACS_INT, not int, to count objects.
11218 (total_conses, total_markers, total_symbols, total_vector_size)
11219 (total_free_conses, total_free_markers, total_free_symbols)
11220 (total_free_floats, total_floats, total_free_intervals)
11221 (total_intervals, total_strings, total_free_strings):
11222 Now EMACS_INT, not int. All uses changed.
11223 (Fgarbage_collect): Compute overall total using a double, so that
11224 integer overflow is less likely to be a problem. Check for overflow
11225 when converting back to an integer.
11226 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11227 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11228 These were 'int' variables that could overflow on 64-bit hosts;
11229 they were never used, so remove them instead of repairing them.
11230 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11231 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
11232 Previously, this ceilinged at INT_MAX, but that doesn't work on
11234 (allocate_pseudovector): Don't use EMACS_INT when int would do.
11236 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
11237 (allocate_vectorlike): Check for ptrdiff_t overflow.
11238 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
11239 when a (possibly-narrower) signed value would do just as well.
11240 We prefer using signed arithmetic, to avoid comparison confusion.
11242 * alloc.c: Catch some string size overflows that we were missing.
11243 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
11244 for convenience in STRING_BYTES_MAX.
11245 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11246 The definition here is exact; the one in lisp.h was approximate.
11247 (allocate_string_data): Check for string overflow. This catches
11248 some instances we weren't catching before. Also, it catches
11249 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11250 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11251 and ptrdiff_t and EMACS_INT are both 64 bits.
11253 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11254 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
11255 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
11257 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
11259 * alloc.c (Fmake_string): Check for out-of-range init.
11261 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
11263 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
11265 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
11267 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
11268 xg_get_default_scrollbar_width.
11270 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
11271 (int_gtk_range_get_value): Move to the scroll bar part of the file.
11272 (style_changed_cb): Call update_theme_scrollbar_width and call
11273 x_set_scroll_bar_default_width and xg_frame_set_char_size for
11274 all frames (Bug#8505).
11275 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
11276 Call gtk_window_set_resizable if HAVE_GTK3.
11277 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
11278 and height if HAVE_GTK3 (Bug#8505).
11279 (scroll_bar_width_for_theme): New variable.
11280 (update_theme_scrollbar_width): New function.
11281 (xg_get_default_scrollbar_width): Move code to
11282 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
11283 (xg_initialize): Call update_theme_scrollbar_width.
11285 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
11287 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
11289 2011-06-12 Martin Rudalics <rudalics@gmx.at>
11291 * frame.c (make_frame): Call other_buffer_safely instead of
11294 * window.c (temp_output_buffer_show): Call display_buffer with
11295 second argument Vtemp_buffer_show_specifiers and reset latter
11296 immediately after the call.
11297 (Vtemp_buffer_show_specifiers): New variable.
11298 (auto_window_vscroll_p, next_screen_context_lines)
11299 (Vscroll_preserve_screen_position): Remove leading asterisks from
11302 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
11304 Fix minor problems found by GCC 4.6.0 static checking.
11305 * buffer.c (Qclone_number): Remove for now, as it's unused.
11306 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
11307 (record_buffer): Remove unused local.
11308 * frame.c (other_visible_frames, frame_buffer_list): Now static.
11309 (set_frame_buffer_list): Remove; unused.
11310 * frame.h (other_visible_frames): Remove decl.
11311 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
11312 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
11313 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
11315 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
11316 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
11317 Define only if HAVE_GPM.
11318 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
11319 (update_hints_inhibit): Remove; never set. All uses removed.
11320 * widgetprv.h (emacsFrameClassRec): Remove decl.
11321 * window.c (delete_deletable_window): Now returns void, since it
11322 wasn't returning anything.
11323 (compare_window_configurations): Remove unused locals.
11324 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
11325 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
11326 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
11327 the same widths as pointers. This follows up on the 2011-05-06 patch.
11328 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.

11792 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
11793 New error handlers.
11794 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
11795 Obey Vx_select_enable_clipboard_manager. Catch errors in
11796 x_clipboard_manager_save (Bug#8779).
11797 (Vx_select_enable_clipboard_manager): New variable.
11798 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
11800 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
11802 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
11804 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11806 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
11807 in the current matrix if keep_current_p is non-zero.

11813 2011-06-03 Eli Zaretskii <eliz@gnu.org>
11815 Support bidi reordering of text covered by display properties.
11817 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
11818 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
11819 (bidi_cache_search, bidi_cache_iterator_state)
11820 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11821 (bidi_level_of_next_char, bidi_move_to_visually_next):
11822 Support character positions inside a run of characters covered by a
11824 (bidi_paragraph_init, bidi_resolve_explicit_1)
11825 (bidi_level_of_next_char): Call bidi_fetch_char and
11826 bidi_fetch_char_advance instead of FETCH_CHAR and
11827 FETCH_CHAR_ADVANCE.

11829 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11831 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11832 instead of using explicit *_CHAR codes.
11833 (bidi_resolve_explicit, bidi_resolve_weak):
11834 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11835 bidirectional text is supported only in multibyte buffers.
11836 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11837 it to initialize the frame_window_p member of struct bidi_it.
11838 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11839 (bidi_resolve_explicit, bidi_resolve_weak)

11841 bidi_it->nchars is non-positive.
11842 (bidi_level_of_next_char): Don't try to lookup the cache for the
11843 next/previous character if nothing is cached there yet, or if we
11844 were just reseat()'ed to a new position.
11846 * xdisp.c (set_cursor_from_row): Set start and stop points
11847 according to the row's direction when priming the loop that looks
11848 for the glyph on which to display cursor.
11849 (single_display_spec_intangible_p): Function deleted.
11850 (display_prop_intangible_p): Reimplement to call
11851 handle_display_spec instead of single_display_spec_intangible_p.
11852 Accept 3 additional arguments needed by handle_display_spec.
11853 This fixes incorrect cursor motion across display property with complex
11854 values: lists, `(when COND...)' forms, etc.
11855 (single_display_spec_string_p): Support property values that are
11856 lists with the argument STRING its top-level element.
11857 (display_prop_string_p): Fix the condition for processing a
11858 property that is a list to be consistent with handle_display_spec.
11859 (handle_display_spec): New function, refactored from the
11860 last portion of handle_display_prop.
11861 (compute_display_string_pos): Accept additional argument
11862 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11863 value of a `display' property is a "replacing spec".
11864 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11865 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11866 the display property, but just return a value indicating whether
11867 the display property will replace the characters it covers.
11868 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11869 frame_window_p members of struct bidi_it.
11870 (compute_display_string_pos, compute_display_string_end):
11872 (push_it): Accept second argument POSITION, where pop_it should
11873 jump to continue iteration.
11874 (reseat_1): Initialize bidi_it.disp_pos.
11876 * keyboard.c (adjust_point_for_property): Adjust the call to
11877 display_prop_intangible_p to its new signature.
11879 * dispextern.h (struct bidi_it): New member frame_window_p.
11880 (bidi_init_it): Update prototypes.
11881 (display_prop_intangible_p): Update prototype.
11882 (compute_display_string_pos, compute_display_string_end):
11883 Declare prototypes.
11884 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11887 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>

11890 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11891 * lisp.h: Change signatures accordingly.
11892 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11893 All callers changed. (Bug#8762)
11895 * gnutls.c: Use Emacs's memory allocators.
11896 Without this change, the gnutls library would invoke malloc etc.
11897 directly, which causes problems on non-SYNC_INPUT hosts, and which
11898 runs afoul of improving memory_full behavior. (Bug#8761)
11899 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11900 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11901 xfree instead of the default malloc, realloc, free.
11902 (Fgnutls_boot): No need to check for memory allocation failure,
11903 since xmalloc does that for us.
11905 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11906 * category.c (hash_get_category_set):
11907 * ccl.c (ccl_driver):
11908 * charset.c (Fdefine_charset_internal):

11919 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11920 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11921 * image.c (make_image, search_image_cache, lookup_image)
11922 (xpm_put_color_table_h):
11923 * lisp.h (struct Lisp_Hash_Table):
11924 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11925 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11926 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11927 * alloc.c (allocate_vectorlike):
11928 Check for overflow in vector size calculations.
11929 * ccl.c (ccl_driver):
11930 Check for overflow when converting EMACS_INT to int.
11931 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11932 need to be updated by these changes.
11933 * fns.c (make_hash_table, maybe_resize_hash_table):
11934 Check for integer overflow with large hash tables.
11935 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11936 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11937 (SXHASH_REDUCE): New macro.
11938 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11939 Use it instead of discarding useful hash info with large hash values.
11940 (sxhash_float): New function.
11941 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11942 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11943 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11944 Rewrite to use FIXNUM_BITS, as this simplifies things.
11945 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11946 Adjust signatures to match updated version of code.
11947 (consing_since_gc): Now EMACS_INT, since a single hash table can
11948 use more than INT_MAX bytes.
11950 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11952 Make it possible to build with GCC-4.6+ -O2 -flto.
11954 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11956 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11958 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11959 Call minibuffer-inactive-mode.
11961 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11963 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11964 Update dependencies.
11966 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11968 * data.c (init_data): Remove code for UTS, this system is not
11971 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11973 Don't force ./temacs to start in terminal mode.
11975 * frame.c (make_initial_frame): Initialize faces in all cases, not
11976 only when CANNOT_DUMP is defined.
11977 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11979 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11981 * dispnew.c (add_window_display_history): Use const for the string
11982 pointer. Remove declaration, not needed.
11984 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11986 Use 'inline', not 'INLINE'.
11987 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11988 * alloc.c, fontset.c (INLINE): Remove.
11989 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11990 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11991 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11992 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11993 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11995 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11997 Make it possible to run ./temacs.
11999 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
12000 syms_of_callproc does the same thing. Remove test for
12001 "initialized", do it in the caller.
12002 * emacs.c (main): Avoid calling set_initial_environment when dumping.
12004 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
12006 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
12007 (read_minibuf): Use get_minibuffer.
12008 (syms_of_minibuf): Use DEFSYM.
12009 (Qmetadata): New var.
12010 * data.c (Qbuffer): Don't make it static.
12011 (syms_of_data): Use DEFSYM.
12013 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12015 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
12016 (CCL_CODE_MIN): New macro.
12018 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
12020 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
12022 * eval.c (Qdebug): Now static.
12023 * lisp.h (Qdebug): Remove decl. This reverts a part of the
12024 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
12025 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
12027 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12029 * image.c: Various fixes to ImageMagick code comments.
12030 (Fimagemagick_types): Doc fix.
12032 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
12034 Minor fixes prompted by GCC 4.6.0 warnings.
12036 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12038 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12039 (x_clipboard_manager_save_all): Move extern decl to ...
12040 * xterm.h: ... here, so that it can be checked for consistency.
12042 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12044 * xselect.c (x_clipboard_manager_save_frame)
12045 (x_clipboard_manager_save_all): New functions.
12046 (Fx_clipboard_manager_save): Lisp function deleted.
12048 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12049 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12051 * xterm.h: Update prototype.
12053 2011-05-28 William Xu <william.xwl@gmail.com>
12055 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12056 exiting (Bug#8239).
12058 2011-05-28 Jim Meyering <meyering@redhat.com>
12060 Avoid a sign-extension bug in crypto_hash_function.
12061 * fns.c (to_uchar): Define.
12062 (crypto_hash_function): Use it to convert some newly-signed
12063 variables to unsigned, to avoid sign-extension bugs. For example,
12064 without this change, (md5 "truc") would evaluate to
12065 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12066 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12067 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12069 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12071 Integer overflow fixes.
12073 * dbusbind.c: Serial number integer overflow fixes.
12074 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12075 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12076 to hold a serial number that is too large for a fixnum.
12077 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12078 Check for serial numbers out of range. Decode any serial number
12079 that was so large that it became a float. (Bug#8722)
12081 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12082 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12083 Use XFASTINT rather than XUINT when numbers are nonnegative.
12084 (xd_append_arg, Fdbus_method_return_internal):
12085 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12086 arguments, check that Lisp number is nonnegative, rather than
12087 silently wrapping negative numbers around. (Bug#8722)
12088 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12091 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12093 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12095 ccl: Add integer overflow checks.
12096 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12097 (IN_INT_RANGE): New macros.
12098 (ccl_driver): Use them to check for integer overflow when
12099 decoding a CCL program. Many of the new checks are whether XINT (x)
12100 fits in int; it doesn't always, on 64-bit hosts. The new version
12101 doesn't catch all possible integer overflows, but it's an
12102 improvement. (Bug#8719)
12104 * alloc.c (make_event_array): Use XINT, not XUINT.
12105 There's no need for unsigned here.
12107 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12108 This follows up to the 2011-05-06 change that substituted uintptr_t
12109 for EMACS_INT. This case wasn't caught back then.
12111 Rework Fformat to avoid integer overflow issues.
12112 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12113 now (part of C89). Include <verify.h>.
12114 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12115 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12116 (Fformat): Avoid the prepass trying to compute sizes; it was only
12117 approximate and thus did not catch overflow reliably. Instead, walk
12118 through the format just once, formatting and computing sizes as we go,
12119 checking for integer overflow at every step, and allocating a larger
12120 buffer as needed. Keep track separately whether the format is
12121 multibyte. Keep only the most-recently calculated precision, rather
12122 than them all. Record whether each argument has been converted to
12123 string. Use EMACS_INT, not int, for byte and char and arg counts.
12124 Support field widths and precisions larger than INT_MAX. Avoid
12125 sprintf's undefined behavior with conversion specifications such as %#d
12126 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12127 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12128 formatting out-of-range floating point numbers with int
12129 formats. (Bug#8668)
12131 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12133 * data.c: Avoid integer truncation in expressions involving floats.
12134 * data.c: Include <intprops.h>.
12135 (arith_driver): When there's an integer overflow in an expression
12136 involving floating point, convert the integers to floating point
12137 so that the resulting value does not suffer from catastrophic
12138 integer truncation. For example, on a 64-bit host (* 4
12139 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12140 Do not rely on undefined behavior after integer overflow.
12142 merge count_size_as_multibyte, parse_str_to_multibyte
12143 * character.c, character.h (count_size_as_multibyte):
12144 Rename from parse_str_to_multibyte; all uses changed.
12145 Check for integer overflow.
12146 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12147 since it's now a duplicate of the other. This is more of
12148 a character than a buffer op, so better that it's in character.c.
12149 * fns.c, print.c: Adjust to above changes.
12151 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12153 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12155 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12157 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12158 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12159 (x_clipboard_manager_save): Now static.
12160 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12162 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12163 (crypto_hash_function): Now static.
12164 Fix pointer signedness problems. Avoid unnecessary initializations.
12166 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12168 * termhooks.h (Vselection_alist): Make it terminal-local.
12170 * terminal.c (create_terminal): Initialize it.
12172 * xselect.c: Support for clipboard managers.
12173 (Vselection_alist): Move to termhooks.h as terminal-local var.
12174 (LOCAL_SELECTION): New macro.
12175 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12176 (symbol_to_x_atom): Remove gratuitous arg.
12177 (x_handle_selection_request, lisp_data_to_selection_data)
12178 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12179 (x_own_selection, x_get_local_selection, x_convert_selection):
12180 New arg, specifying work frame. Use terminal-local Vselection_alist.
12181 (some_frame_on_display): Delete unused function.
12182 (Fx_own_selection_internal, Fx_get_selection_internal)
12183 (Fx_disown_selection_internal, Fx_selection_owner_p)
12184 (Fx_selection_exists_p): New optional frame arg.
12185 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12186 (x_handle_selection_clear): Don't treat other terminals with the
12187 same keyboard specially. Use the terminal-local Vselection_alist.
12188 (x_clear_frame_selections): Use Frun_hook_with_args.
12190 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12192 * xterm.h: Add support for those atoms.
12194 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12196 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12197 (converted_selections, conversion_fail_tag): New global variables.
12198 (x_selection_request_lisp_error): Free the above.
12199 (x_get_local_selection): Remove unnecessary code.
12200 (x_reply_selection_request): Args changed; handle arbitrary array
12201 of converted selections stored in converted_selections.
12202 Separate the XChangeProperty and SelectionNotify steps.
12203 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12204 (x_convert_selection): New function.
12205 (x_handle_selection_event): Simplify.
12206 (x_get_foreign_selection): Don't ignore incoming requests while
12207 waiting for an answer; this will fail when we implement
12208 SAVE_TARGETS, and seems unnecessary anyway.
12209 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12210 (Vx_sent_selection_functions): Doc fix.
12212 2011-05-26 Leo Liu <sdl.web@gmail.com>
12214 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12216 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12218 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12220 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12221 for fringe update if it has periodic bitmap.
12222 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12223 and fringe_bitmap_periodic_p.
12225 * fringe.c (get_fringe_bitmap_data): New function.
12226 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12227 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12228 row. Mark glyph row for fringe update if periodicity changed.
12230 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12231 for fringe update unless it has periodic bitmap.
12233 2011-05-25 Kenichi Handa <handa@m17n.org>
12235 * xdisp.c (get_next_display_element): Set correct it->face_id for
12236 a static composition.
12238 2011-05-24 Leo Liu <sdl.web@gmail.com>
12241 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12243 * fns.c (crypto_hash_function, Fsha1): New function.
12244 (Fmd5): Use crypto_hash_function.
12245 (syms_of_fns): Add Ssha1.
12247 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12249 * gnutls.c: Remove unused macros.
12250 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12251 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12252 Remove macros that are defined and never used.
12253 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12255 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12257 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12258 (Fx_get_selection_internal): Minor cleanup.
12259 (Fx_own_selection_internal): Rename arguments for consistency with
12262 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12264 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12266 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12268 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12270 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12272 * dispnew.c (scrolling_window): Don't exclude the case that the
12273 last enabled row in the desired matrix touches the bottom boundary.
12275 2011-05-21 Glenn Morris <rgm@gnu.org>
12277 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12278 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12279 and add some more files.
12281 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12283 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12284 report_file_error introduced by the change from 2011-05-07.
12286 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12288 * systime.h (Time): Define only if emacs is defined.
12289 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12290 where the include path doesn't have X11/X.h by default. See
12291 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12293 2011-05-20 Kenichi Handa <handa@m17n.org>
12295 * composite.c (find_automatic_composition): Fix previous change.
12297 2011-05-20 Glenn Morris <rgm@gnu.org>
12299 * lisp.mk: New file, split from Makefile.in.
12300 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12301 (shortlisp): Remove.
12302 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12304 2011-05-19 Glenn Morris <rgm@gnu.org>
12306 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12307 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12308 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12309 (lisp): Set the order to that of loadup.el.
12310 (shortlisp): Make it a copy of $lisp.
12311 (SOME_MACHINE_LISP): Remove.
12312 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12313 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12315 2011-05-18 Kenichi Handa <handa@m17n.org>
12317 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12318 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12319 (find_automatic_composition): Mostly rewrite for efficiency.
12321 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12323 * makefile.w32-in: Update dependencies.
12325 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12327 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12328 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12330 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12332 Fix some integer overflow issues, such as string length overflow.
12334 * insdel.c (count_size_as_multibyte): Check for string overflow.
12336 * character.c (lisp_string_width): Check for string overflow.
12337 Use EMACS_INT, not int, for string indexes and lengths; in
12338 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12339 the resulting string length overflows an EMACS_INT; instead,
12340 report a string overflow if no precision given. When checking for
12341 precision exhaustion, use a check that cannot possibly have
12342 integer overflow. (Bug#8675)
12343 * character.h (lisp_string_width): Adjust to new signature.
12345 * alloc.c (string_overflow): New function.
12346 (Fmake_string): Use it. This doesn't change behavior, but saves
12347 a few bytes and will simplify future changes.
12348 * character.c (string_escape_byte8): Likewise.
12349 * lisp.h (string_overflow): New decl.
12351 Fixups, following up to the user-interface timestamp change.
12352 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12353 for UI timestamps, instead of unsigned long.
12354 * msdos.c (mouse_get_pos): Likewise.
12355 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12356 * w32gui.h (Time): Define by including "systime.h" rather than by
12357 declaring it ourselves. (Bug#8664)
12359 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12360 * image.c (clear_image_cache): Likewise.
12362 * term.c (term_mouse_position): Don't assume time_t wraparound.
12364 Be more systematic about user-interface timestamps.
12365 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12366 and sometimes 'EMACS_UINT', to represent these timestamps.
12367 This change causes it to use 'Time' uniformly, as that's what X uses.
12368 This makes the code easier to follow, and makes it easier to catch
12369 integer overflow bugs such as Bug#8664.
12370 * frame.c (Fmouse_position, Fmouse_pixel_position):
12371 Use Time, not unsigned long, for user-interface timestamps.
12372 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12373 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12374 * keyboard.h (last_event_timestamp): Likewise.
12375 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12376 * menu.h (xmenu_show): Likewise.
12377 * term.c (term_mouse_position): Likewise.
12378 * termhooks.h (struct input_event.timestamp): Likewise.
12379 (struct terminal.mouse_position_hook): Likewise.
12380 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12381 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12382 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12383 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12384 what it was before.
12385 * menu.h, termhooks.h: Include "systime.h", for Time.
12387 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12388 Don't assume that the difference between two unsigned long values
12389 can fit into an integer. At this point, we know button_down_time
12390 <= event->timestamp, so the difference must be nonnegative, so
12391 there's no need to cast the result if double-click-time is
12392 nonnegative, as it should be; check that it's nonnegative, just in
12393 case. This bug is triggered when events are more than 2**31 ms
12394 apart (about 25 days). (Bug#8664)
12396 * xselect.c (last_event_timestamp): Remove duplicate decl.
12397 (x_own_selection): Remove needless cast to unsigned long.
12399 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12400 that always fit in int. Use a sentinel instead of a counter, to
12401 avoid a temp and to allay GCC's concerns about possible int overflow.
12402 * frame.h (struct frame): Use int for menu_bar_items_used
12403 instead of EMACS_INT, since it always fits in int.
12405 * menu.c (grow_menu_items): Check for int overflow.
12407 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12409 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12410 Before, the code was not consistent. These values cannot exceed
12411 2**31 - 1 so there's no need to make them unsigned.
12412 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12413 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12414 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12416 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12418 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12419 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12420 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12421 presumably because the widths might not match.
12423 * window.c (size_window): Avoid needless test at loop start.
12425 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12427 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12429 2011-05-12 Drew Adams <drew.adams@oracle.com>
12431 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12433 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12435 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12436 `width' to `bar_area_x' and `bar_area_width', respectively.
12437 (x_scroll_run): Take account of fringe background extension.
12439 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12440 Rename local vars `left' and `width' to `bar_area_x' and
12441 `bar_area_width', respectively.
12442 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12443 background extension.
12445 2011-05-10 Jim Meyering <meyering@redhat.com>
12447 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12449 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12451 * image.c (Finit_image_library): Return t for built-in image types,
12452 like pbm and xbm. (Bug#8640)
12454 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12456 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12458 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12460 * w32console.c (Fset_screen_color): Doc fix.
12461 (Fget_screen_color): New function.
12462 (syms_of_ntterm): Defsubr it.
12464 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12465 unlink the temporary file if Fcall_process didn't create it in the
12467 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12468 child process will be redirected to a file specified with `:file'.
12469 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12470 cue to call_process_cleanup not to close that handle.
12472 2011-05-07 Ben Key <bkey76@gmail.com>
12474 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12475 one of two shell specific rules, either bootstrap-temacs-CMD or
12476 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12477 to the previous implementation of the bootstrap-temacs rule.
12478 The bootstrap-temacs-CMD rule is similar to the previous
12479 implementation of the bootstrap-temacs rule except that it
12480 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12483 These changes, along with some changes to nt/configure.bat,
12484 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12485 earlier fix to add support for --cflags and --ldflags options
12486 that include quotes so that it works whether make uses cmd or
12489 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12491 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12492 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12494 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12495 a string. Handle both cases.
12496 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12497 (Fdbus_register_method): Use Qinvalid_function.
12499 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12501 * makefile.w32-in: Update dependencies.
12502 (LISP_H): Add inttypes.h and stdin.h.
12503 (PROCESS_H): Add unistd.h.
12505 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12507 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12508 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12510 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12512 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12514 * term.c (vfatal): Remove stray call to va_end.
12515 It's not needed and the C Standard doesn't allow it here anyway.
12517 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12518 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12520 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12523 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12525 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12527 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12529 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12531 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12533 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12534 * charset.c (Fdefine_charset_internal): Don't initialize
12535 charset.code_space[15]. The value was garbage, on hosts with
12536 32-bit int (Bug#8600).
12538 * lread.c (read_integer): Be more consistent with string-to-number.
12539 Use string_to_number to do the actual conversion; this avoids
12540 rounding errors and fixes some other screwups. Without this fix,
12541 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12542 (digit_to_number): Move earlier, for benefit of read_integer.
12543 Return -1 if the digit is out of range for the base, -2 if it is
12544 not a digit in any supported base. (Bug#8602)
12546 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12548 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12549 to match comment at start of function. This also removes a
12550 GCC warning about overflow in a 32+64-bit port.
12552 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12554 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12555 Reported by Stefan Monnier in
12556 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12557 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12558 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12560 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12561 (EMACS_UINTPTR): Likewise, with uintptr_t.
12563 * lisp.h: Prefer 64-bit EMACS_INT if available.
12564 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12565 on 32-bit hosts that have 64-bit int, so that they can access
12567 However, temporarily disable this change unless the temporary
12568 symbol WIDE_EMACS_INT is defined.
12570 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12572 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12573 This removes an assumption that EMACS_INT and long are the same
12574 width as pointers. The assumption is true for Emacs porting targets
12575 now, but we want to make other targets possible.
12576 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12577 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12578 In the rest of the code, change types of integers that hold casted
12579 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12580 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12581 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12582 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12583 No need to cast type when ORing.
12584 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12585 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12586 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12587 assume EMACS_INT is the same width as char *.
12588 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12589 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12590 Remove no-longer-needed casts.
12591 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12592 (xg_tool_bar_help_callback, xg_make_tool_item):
12593 Use EMACS_INTPTR to hold an integer
12594 that will be cast to void *; this can avoid a GCC warning
12595 if EMACS_INT is not the same width as void *.
12596 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12597 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12598 (current_message_1, set_message_1):
12599 Use a local to convert to proper width without a cast.
12600 * xmenu.c (dialog_selection_callback): Likewise.
12602 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12603 Also, don't assume VALBITS / RAND_BITS is less than 5,
12604 and don't rely on undefined behavior when shifting a 1 left into
12606 * lisp.h (get_random): Change signature to match.
12608 * lread.c (hash_string): Use size_t, not int, for hash computation.
12609 Normally we prefer signed values; but hashing is special, because
12610 it's better to use unsigned division on hash table sizes so that
12611 the remainder is nonnegative. Also, size_t is the natural width
12612 for hashing into memory. The previous code used 'int', which doesn't
12613 retain enough info to hash well into very large tables.
12614 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12616 * dbusbind.c: Don't possibly lose pointer info when converting.
12617 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12618 Use XPNTR rather than XHASH, so that the high-order bits of
12619 the pointer aren't lost when converting through void *.
12621 * eval.c (Fautoload): Don't double-shift a pointer.
12623 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12625 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12627 * gnutls.c (DEF_GNUTLS_FN):
12628 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12630 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12632 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12635 2011-05-05 Eli Zaretskii <eliz@gnu.org>

12706 * process.c: Include lisp.h before w32.h, not after.
12707 (wait_reading_process_output): Call emacs_gnutls_record_check_pending

12712 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12714 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

12760 rather than `XVECTOR (FOO)->size'.
12762 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12763 inttypes.h, as a gnulib replacement is used if it not available in
12766 2011-04-21 Eli Zaretskii <eliz@gnu.org>

12785 %llo or %llx format is passed. (Bug#8545)
12787 * window.c (window_scroll_line_based): Use a marker instead of
12788 simple variables to record original value of point. (Bug#7952)
12790 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12791 produced by %s or %c overflows available buffer space. (Bug#8545)
12793 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12795 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12796 (SIZE_MAX): Move defn after all includes, as they might #define it.
12798 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12800 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12802 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12804 * keyboard.c (Qdelayed_warnings_hook): Define.
12805 (command_loop_1): Run `delayed-warnings-hook'
12806 if Vdelayed_warnings_list is non-nil.
12807 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12808 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12810 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12812 * doprnt.c (doprnt): Don't return value smaller than the buffer
12813 size if the message was truncated. (Bug#8545).
12815 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12817 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12818 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12820 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12822 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12824 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12826 * makefile.w32-in: Update dependencies.
12828 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12830 Improve `doprnt' and its usage. (Bug#8545)
12831 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12832 `format_end'. Remove support for %l as a conversion specifier.
12833 Don't use xrealloc. Improve diagnostics when the %l size modifier
12834 is used. Update the commentary.
12836 * eval.c (verror): Simplify calculation of size_t.
12838 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12841 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12843 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12846 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12848 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12849 This makes this file independent of the recent pseudovector change.
12851 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12853 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12855 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12856 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12857 Remove unused local.
12858 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12860 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12861 GCC 4.6.0 optimizes based on type-based alias analysis.
12862 For example, if b is of type struct buffer * and v of type struct
12863 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12864 != &v->size, and therefore "v->size = 1; b->size = 2; return
12865 v->size;" must therefore return 1. This assumption is incorrect
12866 for Emacs, since it type-puns struct Lisp_Vector * with many other
12867 types. To fix this problem, this patch adds a new type struct
12868 vectorlike_header that documents the constraints on layout of vectors
12869 and pseudovectors, and helps optimizing compilers not get fooled
12870 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12871 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12872 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12874 (XSETPVECTYPE): Rewrite in terms of new macro.
12875 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12876 This is a bit clearer, and further avoids the possibility of
12877 undesirable aliasing.
12878 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12879 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12880 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12881 since Lisp_Subr is a special case (no "next" field).
12882 (ASIZE): Now uses header.size rather than size.
12883 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12884 to avoid the hassle of writing XVECTOR (foo)->header.size.
12885 (struct vectorlike_header): New type.
12886 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12887 object, to help avoid aliasing.
12888 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12889 (SUBRP): Likewise, since Lisp_Subr is a special case.
12890 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12891 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12892 (struct Lisp_Hash_Table): Combine first two members into a single
12893 struct vectorlike_header member. All uses of "size" and "next" members
12894 changed to be "header.size" and "header.next".
12895 * buffer.h (struct buffer): Likewise.
12896 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12897 * frame.h (struct frame): Likewise.
12898 * process.h (struct Lisp_Process): Likewise.
12899 * termhooks.h (struct terminal): Likewise.
12900 * window.c (struct save_window_data, struct saved_window): Likewise.
12901 * window.h (struct window): Likewise.
12902 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12903 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12904 * buffer.c (init_buffer_once): Likewise.
12905 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12907 * process.c (Fformat_network_address): Use local var for size,
12910 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12912 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12913 * data.c (atof): Remove decl; no longer used or needed.
12914 (digit_to_number): Move to lread.c.
12915 (Fstring_to_number): Use new string_to_number function, to be
12916 consistent with how the Lisp reader treats infinities and NaNs.
12917 Do not assume that floating-point numbers represent EMACS_INT
12918 without losing information; this is not true on most 64-bit hosts.
12919 Avoid double-rounding errors, by insisting on integers when
12920 parsing non-base-10 numbers, as the documentation specifies.
12921 * lisp.h (string_to_number): New decl, replacing ...
12922 (isfloat_string): Remove.
12923 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12924 (read1): Do not accept +. and -. as integers; this
12925 appears to have been a coding error. Similarly, do not accept
12926 strings like +-1e0 as floating point numbers. Do not report
12927 overflow for integer overflows unless the base is not 10 which
12928 means we have no simple and reliable way to continue.
12929 Break out the floating-point parsing into a new
12930 function string_to_number, so that Fstring_to_number parses
12931 floating point numbers consistently with the Lisp reader.
12932 (digit_to_number): Move here from data.c. Make it static inline.
12933 (E_CHAR, EXP_INT): Remove, replacing with ...
12934 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12935 (string_to_number): New function, replacing isfloat_string.
12936 This function checks for valid syntax and produces the resulting
12937 Lisp float number too. Rework it so that string-to-number
12938 no longer mishandles examples like "1.0e+". Use strtoumax,
12939 so that overflow for non-base-10 numbers is reported only when
12940 there's no portable and simple way to convert to floating point.
12942 * textprop.c (set_text_properties_1): Rewrite for clarity,
12943 and to avoid GCC warning about integer overflow.
12945 * intervals.h (struct interval): Use EMACS_INT for members
12946 where EMACS_UINT might cause problems. See
12947 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12948 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12949 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12951 (offset_intervals): Tell GCC not to worry about length overflow
12952 when negating a negative length.
12954 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12955 (overrun_check_free): Likewise.
12957 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12958 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12961 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12962 (gnutls_make_error): Rename local to avoid shadowing.
12963 (gnutls_emacs_global_deinit): ifdef out; not used.
12964 (Fgnutls_boot): Use const for pointer to readonly storage.
12965 Comment out unused local. Fix pointer signedness problems.
12967 * lread.c (openp): Don't stuff size_t into an 'int'.
12968 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12969 about possible signed overflow.
12971 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12972 (GDK_KEY_g): Don't define if already defined.
12973 (xg_prepare_tooltip): Avoid pointer signedness problem.
12974 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12976 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12977 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12979 * xfns.c (Fx_window_property): Simplify a bit,
12980 to make a bit faster and to avoid GCC 4.6.0 warning.
12981 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12983 * fns.c (internal_equal): Don't assume size_t fits in int.
12985 * alloc.c (compact_small_strings): Tighten assertion a little.
12987 Replace pEd with more-general pI, and fix some printf arg casts.
12988 * lisp.h (pI): New macro, generalizing old pEd macro to other
12989 conversion specifiers. For example, use "...%"pI"d..." rather
12990 than "...%"pEd"...".
12991 (pEd): Remove. All uses replaced with similar uses of pI.
12992 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12993 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12994 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12995 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12996 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12997 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12998 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
13000 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
13001 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
13002 * print.c (safe_debug_print, print_object): Likewise.
13003 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
13005 Use pI instead of if-then-else-abort. Use %p to avoid casts,
13006 avoiding the 0 flag, which is not portable.
13007 * process.c (Fmake_network_process): Use pI to avoid cast.
13008 * region-cache.c (pp_cache): Likewise.
13009 * xdisp.c (decode_mode_spec): Likewise.
13010 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
13011 behavior on 64-bit hosts with printf arg.
13012 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
13013 (x_stop_queuing_selection_requests): Likewise.
13014 (x_get_window_property): Don't truncate byte count to an 'int'
13017 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
13018 here, since it parses constructs like leading '-' and spaces,
13019 which are not wanted; and it overflows with large numbers.
13020 Instead, simply match F[0-9]+, which is what is wanted anyway.
13022 * alloc.c: Remove unportable assumptions about struct layout.
13023 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
13024 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
13025 (allocate_vectorlike, make_pure_vector): Use the new macros,
13026 plus offsetof, to remove unportable assumptions about struct layout.
13027 These assumptions hold on all porting targets that I know of, but
13028 they are not guaranteed, they're easy to remove, and removing them
13029 makes further changes easier.
13031 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
13032 This doesn't fix a bug but makes the code clearer.
13033 (string_overrun_cookie): Now const. Use initializers that
13034 don't formally overflow signed char, to avoid warnings.
13035 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
13036 can cause Emacs to crash when string overrun checking is enabled.
13037 (allocate_buffer): Don't assume sizeof (struct buffer) is a
13038 multiple of sizeof (EMACS_INT); it need not be, if
13039 alignof(EMACS_INT) < sizeof (EMACS_INT).
13040 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
13042 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
13044 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
13046 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
13048 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
13049 supposed to be handshaking. (Bug#8556)
13050 Reported by Paul Eggert <eggert@cs.ucla.edu>.
13052 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

13623 * xfaces.c (face_at_string_position):
13624 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
13625 since 0 is always ASCII.

13813 to see whether these functions can be called from other modules.
13814 DEFUN now defines a static function. To make the function external
13815 so that it can be used in other C modules, use the new macro DEFUE.

13891 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13893 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13894 since callers should never pass a negative size.
13895 Change the signature to match that of plain 'read' and 'write'; see
13896 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13897 * lisp.h: Update prototypes of emacs_write and emacs_read.
13899 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13901 * xdisp.c (redisplay_window): Don't try to determine the character
13902 position of the scroll margin if the window start point w->startp
13903 is outside the buffer's accessible region. (Bug#8468)
13905 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13907 Fix write-region and its subroutines for buffers > 2GB.
13908 * fileio.c (a_write, e_write): Modify declaration of arguments and
13909 local variables to support buffers larger than 2GB.
13910 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13912 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13913 argument, local variables, and return value.
13915 * lisp.h: Update prototypes of emacs_write and emacs_read.
13917 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13919 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13921 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13923 Fix more problems found by GCC 4.6.0's static checks.
13925 * xdisp.c (vmessage): Use a better test for character truncation.
13927 * charset.c (load_charset_map): <, not <=, for optimization,

13937 * callint.c (Fcall_interactively): <, not <=, for optimization.
13938 (Fcall_interactively): Count the number of arguments produced,
13939 not the number of arguments given. This is simpler and lets GCC
13940 4.6.0 generate slightly better code.
13942 * ftfont.c: Distingish more carefully between FcChar8 and char.
13943 The previous code passed unsigned char * to a functions like
13944 strlen and xstrcasecmp that expect char *, which does not
13945 conform to the C standard.
13946 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13947 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13948 char * when the C standard requires it.
13950 * keyboard.c (read_char): Remove unused var.
13952 * eval.c: Port to Windows vsnprintf (Bug#8435).
13953 Include <limits.h>.
13954 (SIZE_MAX): Define if the headers do not.
13955 (verror): Do not give up if vsnprintf returns a negative count.
13956 Instead, grow the buffer. This ports to Windows vsnprintf, which
13957 does not conform to C99. Problem reported by Eli Zaretskii.
13958 Also, simplify the allocation scheme, by avoiding the need for
13959 calling realloc, and removing the ALLOCATED variable.
13961 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13963 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13964 But keep the doprint source code for now, as we might revamp it
13965 and use it again (Bug#8435).
13966 * lisp.h (doprnt): Remove.
13967 * Makefile.in (base_obj): Remove doprnt.o.
13968 * deps.mk (doprnt.o): Remove.
13970 error: Print 32- and 64-bit integers portably (Bug#8435).
13971 Without this change, on typical 64-bit hosts error ("...%d...", N)
13972 was used to print both 32- and 64-bit integers N, which relied on
13973 undefined behavior.
13974 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13975 * lisp.h (error, verror): Mark as printf-like functions.
13976 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13977 Report overflow in size calculations when allocating printf buffer.
13978 Do not truncate output string at its first null byte.
13979 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13980 Truncate the output at a character boundary, since vsnprintf does not
13982 * charset.c (check_iso_charset_parameter): Convert internal
13983 character to string before calling 'error', since %c now has the
13985 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13986 overflow when computing char to be passed to 'error'. Do not
13987 pass Lisp_Object to 'error'; pass the integer instead.
13988 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13989 formatted with plain %d.
13991 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13993 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13995 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13997 * xterm.c (x_catch_errors): Remove duplicate declaration.
13999 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
14001 * xdisp.c, lisp.h (message_nolog): Remove; unused.
14003 2011-04-10 Jim Meyering <meyering@redhat.com>
14005 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
14006 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
14007 return ssize_t not "int", and use size_t as the buffer length.
14008 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
14009 * gnutls.h: Update declarations.
14010 * process.c (read_process_output): Use ssize_t, to match.
14011 (send_process): Likewise.

14015 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
14017 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14019 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
14020 Use unsigned char, to match FcChar8 type definition.
14022 * xterm.c (handle_one_xevent):
14023 * xmenu.c (create_and_show_popup_menu):
14024 * xselect.c (x_decline_selection_request)
14025 (x_reply_selection_request): Avoid type-punned deref of X events.
14027 2011-04-09 Eli Zaretskii <eliz@gnu.org>
14029 Fix some uses of `int' instead of EMACS_INT.
14030 * search.c (string_match_1, fast_string_match)

14034 (Fmatch_data): Make some `int' variables be EMACS_INT.
14036 * xdisp.c (display_count_lines): 3rd argument and return value now
14037 EMACS_INT. All callers changed.
14038 (pint2hrstr): Last argument is now EMACS_INT.
14040 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
14041 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
14042 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

14053 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
14054 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
14056 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
14057 (encode_invocation_designation): Last argument P_NCHARS is now
14059 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
14060 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
14062 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
14065 * ccl.c (Fccl_execute_on_string): Declare some variables
14068 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

14083 instead of using internal_with_output_to_temp_buffer.
14084 (Qhelp_form_show): New var.
14085 (syms_of_keyboard): Use DEFSYM macro.
14087 * print.c (internal_with_output_to_temp_buffer): Function deleted.

14108 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
14110 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
14112 * xdisp.c (vmessage): Mark as a printf-like function.
14114 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

14121 to system-supplied API.
14123 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14125 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14126 This avoids several warnings with gcc -Wstrict-overflow.
14127 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14128 directly, rather than having caller test rule sign. This avoids
14129 some unnecessary tests.
14130 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14131 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14132 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14134 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14135 (xfont_open): Avoid unnecessary tests.
14137 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14139 * composite.h, composite.c (composition_gstring_put_cache):
14140 Use EMACS_INT, not int, for length.

14143 breaking out part of COMPOSITION_DECODE_RULE.
14144 (COMPOSITION_DECODE_RULE): Use it.
14145 * composite.c (get_composition_id): Remove unused local vars,
14146 by using the new macro.
14148 * textprop.c (set_text_properties_1): Change while to do-while,
14149 since the condition is always true at first.
14151 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14152 (interval_deletion_adjustment): Return unsigned value.
14155 * process.c (list_processes_1, create_pty, read_process_output):
14156 (exec_sentinel): Remove vars that were set but not used.
14157 (create_pty): Remove unnecessary "volatile"s.

14171 * print.c (print_error_message): Avoid int overflow.
14173 * font.c (font_list_entities): Redo for clarity,
14174 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14176 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14177 (font_score): Avoid potential overflow in diff calculation.
14179 * fns.c (substring_both): Remove var that is set but not used.
14180 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14182 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14184 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14185 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14186 can always succeed if overflow has undefined behavior.
14188 * search.c (boyer_moore, wordify): Remove vars set but not used.
14189 (wordify): Omit three unnecessary tests.
14191 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
14192 All callers changed. This avoids the need for an unused var.
14194 * casefiddle.c (casify_region): Remove var that is set but not used.
14196 * dired.c (file_name_completion): Remove var that is set but not used.
14198 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
14200 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
14201 (Finsert_file_contents): Remove unnecessary code checking fd.
14203 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14204 Check for integer overflow on size calculations.
14206 * buffer.c (Fprevious_overlay_change): Remove var that is set
14209 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14210 Remove vars that are set but not used.
14211 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
14212 (timer_check_2): Mark vars as initialized.
14214 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
14216 * image.c (lookup_image): Remove var that is set but not used.
14217 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
14219 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14220 that are set but not used.
14222 * xfns.c (make_invisible_cursor): Don't return garbage
14223 if XCreateBitmapFromData fails (Bug#8410).
14225 * xselect.c (x_get_local_selection, x_handle_property_notify):
14226 Remove vars that are set but not used.
14228 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
14229 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
14231 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
14232 Remove var that is set but not used.
14233 (scroll_bar_windows_size): Now size_t, not int.
14234 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
14235 Check for overflow.
14237 * xfaces.c (realize_named_face): Remove vars that are set but not used.
14238 (map_tty_color) [!defined MSDOS]: Likewise.
14240 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14242 * coding.c: Remove vars that are set but not used.
14243 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14244 All callers changed.
14245 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
14246 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
14247 (decode_coding_charset): Remove vars that are set but not used.
14249 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
14250 that is set but not used.
14252 * print.c (print_object): Remove var that is set but not used.
14254 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14255 The gnulib version avoids calling malloc in the usual case,
14256 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14257 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14258 * filelock.c (current_lock_owner): Likewise.
14259 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14260 * sysdep.c: Include allocator.h, careadlinkat.h.
14261 (emacs_no_realloc_allocator): New static constant.
14262 (emacs_readlink): New function.
14263 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14264 ../lib/careadlinkat.h.
14266 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14268 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14269 first non-nil return value).
14271 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
14273 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
14274 if not defined (Bug#8403).

14283 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
14284 and thereabouts. All callers changed.
14285 (get_per_char_metric): Remove parameter `f', unused since
14286 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
14288 2011-04-02 Jim Meyering <meyering@redhat.com>
14290 do not dereference NULL upon failed strdup
14291 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
14292 (ns_get_family): Likewise.
14294 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14296 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
14298 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
14300 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
14303 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
14305 Add lexical binding.
14307 * window.c (Ftemp_output_buffer_show): New fun.

14316 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
14318 (syms_of_lread): Declare `lexical-binding'.
14320 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
14322 * keyboard.c (eval_dyn): New fun.
14323 (menu_item_eval_property): Use it.
14325 * image.c (parse_image_spec): Use Ffunctionp.
14327 * fns.c (concat, mapcar1): Accept byte-code-functions.
14329 * eval.c (Fsetq): Handle lexical vars.
14330 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
14331 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
14332 (FletX, Flet): Obey lexical binding.
14333 (Fcommandp): Handle closures.
14334 (Feval): New `lexical' arg.
14335 (eval_sub): New function extracted from Feval. Use it almost
14336 everywhere where Feval was used. Look up vars in lexical env.
14338 (Ffunctionp): Move from subr.el.
14339 (Ffuncall): Handle closures.
14340 (apply_lambda): Remove `eval_flags'.
14341 (funcall_lambda): Handle closures and new byte-code-functions.
14342 (Fspecial_variable_p): New function.
14343 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14344 but without exporting it to Lisp.
14346 * doc.c (Fdocumentation, store_function_docstring):
14347 * data.c (Finteractive_form): Handle closures.
14349 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14352 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14354 (exec_byte_code): New function extracted from Fbyte_code to handle new
14355 calling convention for byte-code-functions. Add new byte-codes.
14357 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14359 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14361 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14363 * xdisp.c (redisplay_internal): Fix prototype.
14365 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14367 * xdisp.c (SCROLL_LIMIT): New macro.
14368 (try_scrolling): Use it when setting scroll_limit.
14369 Limit scrolling to 100 screen lines.
14370 (redisplay_window): Even when falling back on "recentering",
14371 position point in the window according to scroll-conservatively,
14372 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14374 (try_scrolling): When point is above the window, allow searching
14375 as far as scroll_max, or one screenful, to compute vertical
14376 distance from PT to the scroll margin position. This prevents
14377 try_scrolling from unnecessarily failing when
14378 scroll-conservatively is set to a value slightly larger than the
14379 window height. Clean up the case of PT below the margin at bottom
14380 of window: scroll_max can no longer be INT_MAX. When aggressive
14381 scrolling is in use, don't let point enter the opposite scroll
14382 margin as result of the scroll.
14383 (syms_of_xdisp) <scroll-conservatively>: Document the
14384 threshold of 100 lines for never-recentering scrolling.

14391 (message_log_check_duplicate): Remove parameters `prev_bol' and
14392 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14393 (redisplay_internal): Remove parameter `preserve_echo_area',
14394 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14396 * indent.c (Fvertical_motion):
14397 * window.c (window_scroll_pixel_based, Frecenter):
14398 Don't pass `need_y_p' to `move_it_by_lines'.
14400 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14402 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14403 steal a few bits to be more compact.
14404 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14405 Remove unneeded casts.
14407 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14409 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14411 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14412 binding" message (bug#7967).
14414 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14416 Fix more problems found by GCC 4.6.0's static checks.
14418 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14419 Remove unused local var.
14421 * editfns.c (Fmessage_box): Remove unused local var.
14423 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14424 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14425 Omit unused local vars.
14426 * window.c (shrink_windows): Omit unused local var.
14427 * menu.c (digest_single_submenu): Omit unused local var.
14428 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14429 Omit unused local var.
14431 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14432 Don't assume string length fits in int.
14433 (keyremap_step, read_key_sequence): Use size_t for sizes.
14434 (read_key_sequence): Don't check last_real_key_start redundantly.
14436 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14437 instead of alloca (Bug#8344).
14439 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14440 (Fbacktrace_frame): Don't assume nframes fits in int.
14442 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14444 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14447 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14449 * cm.c (calccost): Turn while-do into do-while, for clarity.
14451 * keyboard.c (syms_of_keyboard): Use the same style as later
14452 in this function when indexing through an array. This also
14453 works around GCC bug 48267.
14455 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14457 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

14460 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14462 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14463 This avoids undefined behavior on integer overflow, and is a bit
14464 more convenient anyway since it is compared to a size_t variable.
14466 Variadic C functions now count arguments with size_t, not int.
14467 This avoids an unnecessary limitation on 64-bit machines, which
14468 caused (substring ...) to crash on large vectors (Bug#8344).
14469 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14470 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14471 All variadic functions and their callers changed accordingly.
14472 (struct gcpro.nvars): Now size_t, not int. All uses changed.

14474 * editfns.c (general_insert_function): Likewise.
14475 * eval.c (struct backtrace.nargs, interactive_p)
14476 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14477 (funcall_lambda, mark_backtrace): Likewise.
14478 * fns.c (concat): Likewise.
14479 * frame.c (x_set_frame_parameters): Likewise.
14480 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14481 0 if not found, not -1. All callers changed.
14483 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14484 (stack_copy_size): Now size_t, not int.
14485 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

14490 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14491 All callers changed.
14493 * lisp.h (multibyte_char_to_unibyte):
14494 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14495 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

14497 * cmds.c (internal_self_insert):
14498 * editfns.c (general_insert_function):
14499 * keymap.c (push_key_description):
14500 * search.c (Freplace_match):
14501 * xdisp.c (message_dolog, set_message_1): All callers changed.
14503 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14505 * keyboard.c (safe_run_hook_funcall): New function.
14506 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14507 don't set the hook to nil, but remove the offending function instead.
14508 (Qcommand_hook_internal): Remove, unused.
14509 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14510 Vcommand_hook_internal.
14512 * eval.c (enum run_hooks_condition): Remove.
14513 (funcall_nil, funcall_not): New functions.
14514 (run_hook_with_args): Call each function through a `funcall' argument.
14515 Remove `cond' argument, now redundant.
14516 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14517 (Frun_hook_with_args_until_failure): Adjust accordingly.
14518 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14520 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14522 * dispextern.h (string_buffer_position): Remove declaration.
14524 * print.c (strout): Remove parameter `multibyte', unused since
14525 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14527 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14528 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14529 All callers changed.
14531 * w32.c (_wsa_errlist): Use braces for struct initializers.
14533 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14534 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14535 All callers changed.
14536 (string_buffer_position): Likewise. Also, make static (it's never
14537 used outside xdisp.c).
14538 (cursor_row_p): Remove parameter `w', unused since
14539 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14541 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14542 All callers changed.
14544 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14546 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
14548 2011-03-27 Anders Lindgren <andlind@gmail.com>

14557 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14559 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

14572 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14574 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14575 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14577 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14579 * w32.c (read_unc_volume): Use parameter `henum', instead of
14580 global variable `wget_enum_handle'.
14582 * keymap.c (describe_vector): Remove parameters `indices' and
14583 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14598 * gtkutil.c (xg_maybe_add_timer):
14599 * keyboard.c (readable_events):
14600 * process.c (wait_reading_process_output):
14601 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14603 * insdel.c (adjust_markers_gap_motion):
14604 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

14678 2011-03-23 Julien Danjou <julien@danjou.info>
14680 * term.c (Fsuspend_tty, Fresume_tty):
14681 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14682 * window.c (temp_output_buffer_show):
14683 * insdel.c (signal_before_change):
14684 * frame.c (Fhandle_switch_frame):

14686 * emacs.c (Fkill_emacs):
14687 * editfns.c (save_excursion_restore):
14688 * cmds.c (internal_self_insert):
14689 * callint.c (Fcall_interactively):
14690 * buffer.c (Fkill_all_local_variables):
14691 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14693 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14694 unconditionally since it does the check itself.
14696 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14698 Fix more problems found by GCC 4.5.2's static checks.
14700 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14701 the first time through the loop, since we know p0 < p1 then.
14702 This also avoids a gcc -Wstrict-overflow warning.
14704 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14705 leading to a memory leak, possible in functions like
14706 load_charset_map_from_file that can allocate an unbounded number
14707 of objects (Bug#8318).
14709 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14710 that could (at least in theory) be that large.
14712 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14713 This is less likely to overflow, and avoids undefined behavior if
14714 overflow does occur. All callers changed. Use strtoul to scan
14715 for the unsigned long integer.
14716 (pint2hrstr): Simplify and tune code slightly.
14717 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14727 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14730 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14732 * process.c (Fmake_network_process): Use socklen_t, not int,
14733 where POSIX says socklen_t is required in portable programs.
14734 This fixes a porting bug on hosts like 64-bit HP-UX, where
14735 socklen_t is wider than int (Bug#8277).
14736 (Fmake_network_process, server_accept_connection):
14737 (wait_reading_process_output, read_process_output):
14740 * process.c: Rename or move locals to avoid shadowing.
14741 (list_processes_1, Fmake_network_process):
14742 (read_process_output_error_handler, exec_sentinel_error_handler):
14743 Rename or move locals.
14744 (Fmake_network_process): Define label "retry_connect" only if needed.
14745 (Fnetwork_interface_info): Fix pointer signedness.

14747 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14748 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14750 Make tparam.h and terminfo.c consistent.
14751 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14752 Include tparam.h instead, since it declares them.
14753 * cm.h (PC): Remove extern decl; tparam.h now does this.
14754 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14755 * terminfo.c: Include tparam.h, to check interfaces.
14756 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14757 (tparam): Adjust signature to match interface in tparam.h;
14758 this removes some undefined behavior. Check that outstring and len
14759 are zero, which they always are with Emacs.
14760 * tparam.h (PC, BC, UP): New extern decls.
14762 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14763 (xftfont_open): Rename locals to avoid shadowing.
14765 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14766 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14767 (OTF_TAG_SYM): Omit macro if not needed.
14768 (ftfont_list): Remove unused local.
14769 (get_adstyle_property, ftfont_pattern_entity):
14770 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
14771 Rename locals to avoid shadowing.
14773 * xfont.c (xfont_list_family): Mark var as initialized.
14775 * xml.c (make_dom): Now static.
14777 * composite.c (composition_compute_stop_pos): Rename local to
14779 (composition_reseat_it): Remove unused locals.
14780 (find_automatic_composition, composition_adjust_point): Likewise.
14781 (composition_update_it): Mark var as initialized.
14782 (find_automatic_composition): Mark vars as initialized,
14783 with a FIXME (Bug#8290).
14785 character.h: Rename locals to avoid shadowing.
14786 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14787 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14788 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14789 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14790 to avoid shadowing.
14792 * textprop.c (property_change_between_p): Remove; unused.
14794 * intervals.c (interval_start_pos): Now static.
14796 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
14798 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
14799 Rename locals to avoid shadowing.
14801 * sound.c (wav_play, au_play, Fplay_sound_internal):
14802 Fix pointer signedness.
14803 (alsa_choose_format): Remove unused local var.
14804 (wav_play): Initialize a variable to 0, to prevent undefined
14805 behavior (Bug#8278).
14807 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14809 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14811 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14812 clobbering (Bug#8298).
14813 * sysdep.c (sys_subshell): Likewise.
14814 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14816 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14817 This should get cleaned up, so that child_setup has the
14818 same signature on all platforms.
14820 * callproc.c (call_process_cleanup): Now static.
14821 (relocate_fd): Rename locals to avoid shadowing.
14823 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14825 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14826 not to be necessary, and produces flickering.
14828 2011-03-20 Glenn Morris <rgm@gnu.org>
14830 * config.in: Remove file.
14832 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14834 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14835 are now in src/globals.h.
14836 (syms_of_minibuf): Remove spurious & from previous change.

14951 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14952 some of which prompt warnings from gcc -Wbad-function-cast.

14990 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14991 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14992 to use the following functions instead of these macros.
14993 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14994 EMACS_INT, since callers assume the returned value fits in int.
14995 (upcase1): Likewise, for UPCASE_TABLE.
14996 (uppercasep, lowercasep, upcase): New static inline functions.
14997 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

15007 (regex_compile, re_match_2_internal): Mark locals as initialized.
15008 (RETALLOC_IF): Define only if needed.
15009 (WORDCHAR_P): Likewise. This one is never needed, but is used
15010 only in a comment talking about a compiler bug, so put inside
15011 the #if 0 of that comment.
15012 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
15013 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

15039 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
15040 New macros, so that the caller can use some names other than
15041 gcpro1, gcpro2, etc.
15042 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15044 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15045 argument, for consistency with GCPRO2_VAR, etc: it is now the
15046 prefix of the variable, not the variable itself. All uses
15048 * dired.c (directory_files_internal, file_name_completion):
15049 Rename locals to avoid shadowing.
15051 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15052 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15053 dired.c's scmp function, had undefined behavior.
15054 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15055 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15056 * buffer.h: ... to here, because these macros use current_buffer,
15057 and the new implementation with inline functions needs to have
15058 current_buffer in scope now, rather than later when the macros
15060 (downcase, upcase1): New static inline functions.
15061 (DOWNCASE, UPCASE1): Reimplement using these functions.
15062 This avoids undefined behavior in expressions like
15063 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15064 from race conditions in accessing the global variables
15065 case_temp1 and case_temp2.
15066 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15067 * lisp.h (case_temp1, case_temp2): Remove their decls.
15068 * character.h (ASCII_CHAR_P): Move from here ...
15069 * lisp.h: ... to here, so that the inline functions mentioned
15070 above can use them.
15072 * dired.c (directory_files_internal_unwind): Now static.
15074 * fileio.c (file_name_as_directory, directory_file_name):
15075 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
15077 (file_name_as_directory): Use const pointers when appropriate.
15078 (Fexpand_file_name): Likewise. In particular, newdir might
15079 point at constant storage, so make it a const pointer.
15080 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
15081 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15083 (Fset_file_times, Finsert_file_contents, auto_save_error):

15088 to avoid shadowing.
15090 * marker.c (bytepos_to_charpos): Remove; unused.
15092 * lisp.h (verify_bytepos, count_markers): New decls,
15093 so that gcc does not warn that these functions aren't declared.
15095 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
15096 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
15097 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
15098 (copy_text): Remove unused local var.
15100 * filelock.c (within_one_second): Now static.
15101 (lock_file_1): Rename local to avoid shadowing.
15103 * buffer.c (fix_overlays_before): Mark locals as initialized.
15104 (fix_start_end_in_overlays): Likewise. This function should be
15105 simplified by using pointers-to-pointers, but that's a different
15107 (switch_to_buffer_1): Now static.
15108 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15109 (report_overlay_modification): Rename locals to avoid shadowing.
15111 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
15112 Fix pointer signedness issue.
15113 (sys_subshell): Mark local as volatile if checking for lint,
15114 to suppress a gcc -Wclobbered warning that does not seem to be right.
15115 (MAXPATHLEN): Define only if needed.
15117 * process.c (serial_open, serial_configure): Move decls from here ...
15118 * systty.h: ... to here, so that they can be checked.
15120 * fns.c (get_random, seed_random): Move extern decls from here ...
15121 * lisp.h: ... to here, so that they can be checked.
15123 * sysdep.c (reset_io): Now static.
15124 (wait_for_termination_signal): Remove; unused.
15126 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
15127 (copy_keymap_item, append_key, push_text_char_description):
15129 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
15130 (DENSE_TABLE_SIZE): Remove; unused.
15131 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
15132 (describe_map_tree):
15133 Rename locals to avoid shadowing.
15135 * keyboard.c: Declare functions static if they are not used elsewhere.
15136 (echo_char, echo_dash, cmd_error, top_level_2):
15137 (poll_for_input, handle_async_input): Now static.
15138 (read_char, kbd_buffer_get_event, make_lispy_position):

15220 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
15221 These macros can no longer be used for assignment.

15281 Improve quality of tests for time stamp overflow.
15282 For example, without this patch (encode-time 0 0 0 1 1
15283 1152921504606846976) returns the obviously-bogus value (-948597
