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

718 Remove unnecessary pointer casts.
719 * alloc.c (record_xmalloc): New function.
720 * lisp.h (record_xmalloc): New decl.
721 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
722 more like a function. This is because the pointer cast is not
723 needed. All uses changed.
724 * print.c (print_string, print_error_message): Avoid length recalc.
726 Improve fix for macroexp crash with debugging (Bug#12118).
727 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
728 ARRAY_MARK_FLAG when checking subscripts, because ASET is
729 not supposed to be invoked from the garbage collector.
730 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.

748 headers (most versions of MinGW w32api don't).
749 (get_security_info, create_symbolic_link)
750 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
752 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

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

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

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

830 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
831 This how ASET and AREF are supposed to work, and makes
832 it easier to think about future improvements. See
833 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
834 * charset.h (set_charset_attr): New function.

1326 the fix for 12036 would have avoided some of the problems noted in

1338 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1339 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1340 not be usable in #if. This simplifies things.
1342 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1344 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

1351 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1352 Adjust to changes in lisp.h and emacs.c, by using

1362 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1363 (xreload, hook-run, hookpost-run): Remove.
1364 * emacs.c: Include <verify.h>.
1365 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1366 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
1368 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
1369 (gdb_USE_LSB_TAG): New enum constants.
1370 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

1373 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

2262 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
2263 Prefer snprintf to strncpy.
2264 * nsterm.m (ns_term_init):
2265 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2266 * nsterm.m (ns_term_init):
2267 Avoid the need for strncpy, by using build_string or
2268 make_unibyte_string directly. Use dtoastr, not snprintf.
2269 * process.c (Fmake_network_process): Diagnose service names that
2270 are too long, rather than silently truncating them or creating
2271 non-null-terminated names.

2301 Optimize pure C strings initialization.
2302 * lisp.h (make_pure_string): Fix prototype.
2303 (build_pure_c_string): New function, defined as static inline. This
2304 provides a better opportunity to optimize away calls to strlen when
2305 the function is called with compile-time constant argument.
2306 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2307 argument, adjust users accordingly. Use build_pure_c_string where
2309 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2310 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
2311 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
2313 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2315 Avoid calls to strlen in miscellaneous functions.
2316 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

2318 * lread.c (openp): Likewise.
2320 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2322 Avoid calls to strlen in path processing functions.
2323 * fileio.c (file_name_as_directory): Add comment. Change to add
2324 srclen argument and return the length of result. Adjust users
2326 (directory_file_name): Fix comment. Change to add srclen argument,

2328 Adjust users accordingly.
2329 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2331 2012-07-10 Glenn Morris <rgm@gnu.org>
2333 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

2338 * s/gnu.h (DATA_START): Move definitions to configure.
2340 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2341 We include usg5-4-common.h, which defines them both.
2343 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2344 O_RDONLY already includes it).
2346 Stop ns builds setting the EMACSLOADPATH environment variable.
2347 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2348 Now it does not set EMACSLOADPATH, just returns the load-path string.
2349 * nsterm.h: Update accordingly.
2350 * lread.c [HAVE_NS]: Include nsterm.h.
2351 (init_lread) [HAVE_NS]: Use ns_load_path.

2354 2012-07-09 Glenn Morris <rgm@gnu.org>
2356 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2357 since the included bsd-common.h does so.
2359 Stop ns builds setting the EMACSPATH environment variable.
2360 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2361 (ns_init_paths): Do not set EMACSPATH.
2362 * nsterm.h (ns_exec_path): Add it.
2363 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2366 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2368 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2370 * process.c (wait_reading_process_output): 'waitchannels' was unset
2371 when read_kbd || !NILP (wait_for_cell); fix this.
2373 Add GCC-style 'const' attribute to functions that can use it.
2374 * character.h (char_resolve_modifier_mask):
2375 * keyboard.h (make_ctrl_char):
2376 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

2385 Add decls with ATTRIBUTE_CONST.
2387 Minor improvements to make_formatted_string.
2388 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2389 where int is good enough, as vsprintf returns an int.
2390 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2392 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2394 Use make_formatted_string to avoid double length calculation.
2395 * lisp.h (make_formatted_string): New prototype.
2396 * alloc.c (make_formatted_string): New function.
2397 * buffer.c (Fgenerate_new_buffer_name): Use it.

2419 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2421 Move marker debugging code under MARKER_DEBUG.
2422 * marker.c (MARKER_DEBUG): Move marker debugging code under
2423 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2424 for bootstrap with --enable-checking (~3x slowdown reported
2425 by Juanma Barranquero <lekktu@gmail.com>).
2426 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2428 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2430 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2431 See <http://bugs.gnu.org/11825#29>.
2433 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2435 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2436 has no font, use the frame's font. (Bug#11813)
2437 (display_line): Add commentary about displaying truncation glyphs
2439 (produce_special_glyphs): Move here from term.c.
2441 * term.c (produce_special_glyphs): Move to xdisp.c.
2443 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2446 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2448 * xdisp.c (display_line): Avoid warning about implicit declaration
2451 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2453 * lisp.h: Remove empty conditional.
2455 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2457 * lread.c (load_path_check): Now static.
2459 Fix some minor --with-ns problems found by static checking.
2460 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2461 (x_set_font) [!HAVE_X_WINDOWS]:
2462 * image.c (xpm_load_image) [HAVE_NS]:
2463 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2464 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2465 Remove unused local.
2466 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2467 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2468 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2469 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2470 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2471 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2472 Fix pointer signedness problem.
2473 * xfaces.c (FRAME_X_FONT_TABLE):
2474 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2476 2012-07-07 Glenn Morris <rgm@gnu.org>
2478 * lread.c (load_path_check): New function, split from init_lread.
2479 (init_lread): Reorganize. Motivation:
2480 If EMACSLOADPATH is set, check/warn about that rather than the
2481 defaults, which we are not going to use. Hence we can remove
2482 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2483 Don't warn if site-lisp directories are missing.
2484 If not installed, start from a blank load-path, since
2485 PATH_LOADSEARCH refers to the eventual installation directories.
2487 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2489 Support truncation and continuation glyphs on GUI frames, when
2490 fringes are disabled. (Bug#11832)
2491 * xdisp.c (init_iterator): Get dimensions of truncation and
2492 continuation glyphs even if on GUI frames.
2493 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2494 or both, are absent.
2495 (start_display, move_it_in_display_line_to): Handle the case of a
2496 GUI frame without a fringe to display continuation or truncation
2498 (insert_left_trunc_glyphs): Support GUI frames: make sure
2499 truncation glyphs overwrite enough glyphs from the current line to
2500 have sufficient space in pixels.
2501 (display_line): Support truncation and continuation glyphs on GUI
2502 frames. If some spare pixels are left on the line after inserting
2503 the truncation glyphs, fill that space with a stretch glyph of a
2504 suitably computed width.
2506 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2507 produce_glyphs, to support GUI sessions.
2509 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2511 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2513 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2515 Do not require float-time's arg to fit in time_t (Bug#11825).
2516 This works better on hosts where time_t is unsigned, and where
2517 float-time is applied to the (negative) difference between two times.
2518 * editfns.c (decode_time_components): Last arg is now double *,
2519 not int *, and means to store all the result as a double, without
2520 worrying about whether the seconds part fits in time_t.
2521 All callers changed.
2522 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2523 All callers changed.
2524 (Ffloat_time): Do not fail merely because the specified time falls
2525 outside of time_t range.
2527 2012-07-07 Glenn Morris <rgm@gnu.org>
2529 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2536 Update dependencies.
2538 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2540 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

2544 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2545 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2546 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

2549 * xfont.c (compare_font_names): Redo to omit the need for casts.
2551 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2553 * xfns.c (Fx_change_window_property): Doc fix.
2554 * w32fns.c (Fx_change_window_property): Doc fix.
2556 * w32fns.c (Fx_window_property): Accept the same arguments as the
2557 X Windows version. Doc fix.
2558 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2560 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2561 Eli Zaretskii <eliz@gnu.org>
2563 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2564 Windows-specific code from nt/config.nt moved here.
2565 Obsolete settings removed.
2567 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2569 * process.c: Avoid unnecessary calls to gettime.
2570 (wait_reading_process_output): Don't get the time of day
2571 when gobbling data immediately and not waiting, as there's no need
2572 for it in that case. This removes a FIXME.
2574 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2576 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2577 is defined (Bug#11768).
2579 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2581 Fix marker debugging code.
2582 * marker.c (byte_char_debug_check): Do not perform the check
2583 if buffer is not multibyte.
2584 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2585 Call byte_char_debug_check with correct arguments.
2587 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2589 Compile marker debugging code only if ENABLE_CHECKING is defined.
2590 * marker.c (byte_char_debug_check, count_markers):
2591 Use only if ENABLE_CHECKING is defined.
2592 (byte_debug_flag): Remove.
2593 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2594 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2596 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2598 Avoid code repetition in marker-related functions.
2599 * marker.c (attach_marker): New function.
2600 (Fset_marker, set_marker_restricted, set_marker_both)
2601 (set_marker_restricted_both): Use it.
2602 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2603 Consistently rename charno to charpos.

2624 * window.c (save_window_save): Likewise.
2626 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2628 Do not use Fdelete_overlay in delete_all_overlays
2629 to avoid redundant calls to unchain_overlay.
2630 * buffer.c (drop_overlay): New function.
2631 (delete_all_overlays, Fdelete_overlay): Use it.
2632 * minibuf.c (get_minibuffer): Fix comment.

2636 Port to OpenBSD 5.1 amd64.
2637 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2638 This is needed for OpenBSD, and should be harmless on all BSD systems.
2639 Also, include <sys/sysctl.h>, as it should be available on all
2640 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2641 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2642 use p_pid member, not kp_proc.pid.
2644 2012-07-06 Glenn Morris <rgm@gnu.org>
2646 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2648 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2650 More xmalloc and related cleanup.

2659 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2661 Omit needless casts involving void * pointers and allocation.
2662 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2663 as the former is more robust if P's type is changed.
2664 Prefer xzalloc to xmalloc + memset 0.
2665 Simplify malloc-or-realloc to realloc.
2666 Don't worry about xmalloc returning a null pointer.
2667 Prefer xstrdup to xmalloc + strcpy.
2668 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2670 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2671 alloca of a constant.
2673 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2675 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2676 hscroll is larger than the line width. Fixes long and futile
2677 looping inside extend_face_to_end_of_line (on a TTY) producing
2678 glyphs that are not needed and thrown away.
2680 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2682 * marker.c (set_marker_restricted_both): Simplify by using

2708 * xdisp.c (window_hscroll_limited): New function.
2709 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2710 coordinates when window's hscroll is set to insanely large
2713 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2715 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

2776 * fileio.c (time_error_value): Check the right error number.
2777 Problem reported by Troels Nielsen in
2778 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2780 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2782 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2783 This should be fixed in a better way; see Eli Zaretskii in
2784 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2785 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2787 * fileio.c (time_error_value): Rename from special_mtime.
2788 The old name's problems were noted by Eli Zaretskii in
2789 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2791 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2792 This variable's comment says Emacs needs at least one GDB-visible
2793 symbol of type enum pvec_type, to work around GDB problems.
2794 The symbol's value doesn't matter.
2796 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2797 that causes compilation to fail on pre-C99 compilers.
2799 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2801 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2802 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2804 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2806 * buffer.c (init_buffer_once): Fix initialization of
2807 headers for buffer_defaults and buffer_local_symbols.
2808 Reported by Juanma Barranquero <lekktu@gmail.com>.
2810 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2812 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2813 * lisp.h (enum pvec_type): Use fewer bits.
2814 (PSEUDOVECTOR_SIZE_BITS): New constant.
2815 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2816 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2817 change in pvec_type.
2818 (PSEUDOVECTOR_TYPEP): New macro.
2819 (TYPED_PSEUDOVECTORP): Use it.
2820 * fns.c (internal_equal): Adapt code to extract pvectype.
2821 * emacs.c (gdb_pvec_type): Update type.
2822 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2823 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2824 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2825 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2826 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2827 abusing vector->header.next.nbytes.
2828 (live_vector_p): Use PVEC_TYPE.
2829 (mark_object): Adapt code to extract pvectype. Use switch.
2831 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2833 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2834 Tighten new eassert a bit.
2836 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2838 Fix compilation with --enable-gcc-warnings and -O1
2840 * doprnt.c (doprnt): Change type of tem to int, initialize
2841 to avoid compiler warning. Add eassert.
2842 * search.c (simple_search): Initialize match_byte to avoid
2843 compiler warning. Add eassert.
2845 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2847 Avoid weird behavior with large horizontal scrolls.
2848 Without this change, for example, large hscroll values would
2849 mess up Emacs's display on Fedora 15 x86, presumably due to
2850 overflows in int calculations in the display code.
2851 Also, if buffers had long lines, Emacs would freeze.
2852 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2853 (set_window_hscroll): New function, containing the old guts of
2854 Fset_window_hscroll. Return the clipped value.
2855 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2856 This avoids the need to check against PTRDIFF_MAX.
2858 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2860 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2862 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2864 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2866 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2867 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2868 since GCC 4.4.6 issues a bogus warning for them.
2870 Fix bugs in file timestamp newness comparisons.
2871 * fileio.c (Ffile_newer_than_file_p):
2872 * lread.c (Fload): Use full timestamp resolution of files,
2873 not just the 1-second resolution, so that files that are only
2874 slightly newer still count as newer.
2875 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2876 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2878 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2880 * fileio.c: Improve handling of file time marker. (Bug#11852)
2881 (special_mtime): New function.
2882 (Finsert_file_contents, Fverify_visited_file_modtime):
2883 Use it to set special mtime values consistently.
2885 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2887 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2888 marker for non-existing file. (Bug#11852)
2890 2012-07-03 Glenn Morris <rgm@gnu.org>
2892 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2893 and did not make it into globals.h).
2895 2012-07-03 Tom Tromey <tromey@redhat.com>
2897 * window.c (Fset_window_margins, Fset_window_fringes)
2898 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2899 * textprop.c (Fprevious_property_change): No longer static.
2900 * syntax.c (Fsyntax_table_p): No longer static.

2922 * intervals.h: Remove EXFUNs.
2923 * fontset.h: Remove EXFUN.

2928 * w32term.h: Remove EXFUNs.
2929 * window.h: Remove EXFUNs.
2930 * xsettings.h: Remove EXFUN.
2931 * xterm.h: Remove EXFUN.
2933 2012-07-03 Glenn Morris <rgm@gnu.org>
2935 * lisp.h (Frandom): Make it visible to C.
2936 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2937 buffer for invisible buffers. (Bug#1229)
2939 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2941 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2942 values which aren't power of 2.
2943 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
2944 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2947 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2949 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2951 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2953 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2955 * alloc.c (allocate_vector_block): Remove redundant
2956 calls to mallopt if DOUG_LEA_MALLOC is defined.
2957 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2958 avoid calls to mallopt if zero_vector is returned.
2960 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2962 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2963 is enabled, avoid dereferencing NULL current_sblock if
2966 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2968 Cleanup basic buffer management.
2969 * buffer.h (struct buffer): Change layout to use generic vector
2970 marking code. Fix some comments. Change type of 'clip_changed'
2971 to bitfield. Remove unused #ifndef old.
2972 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2973 (GET_OVERLAYS_AT): Fix indentation.
2974 (for_each_per_buffer_object_at): New macro.
2975 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2978 * alloc.c (allocate_buffer): Adjust to match new layout of
2979 struct buffer. Fix comment.
2980 (mark_overlay): New function.

2983 (mark_object): Use it. Adjust marking of misc objects
2984 and related comments.
2986 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2988 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2989 wrapper that is not needed because the wrapped code is a no-op (zero
2990 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2991 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2993 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2995 * alloc.c (mark_buffer): Simplify. Remove prototype.
2996 (mark_object): Add comment. Reorganize marking of vector-like
2997 objects. Use CHECK_LIVE for all vector-like objects except buffers
2998 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
2999 Avoid redundant calls to mark_vectorlike for bool vectors.
3001 2012-06-30 Glenn Morris <rgm@gnu.org>
3003 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
3005 * epaths.in (PATH_SITELOADSEARCH): New.
3006 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
3007 This is rather than relying on --enable-locallisppath elements
3008 having "site-lisp" in their names. (Bug#10208#25, 11658)
3010 2012-06-30 Eli Zaretskii <eliz@gnu.org>
3012 * w32proc.c (sys_select): Accept and ignore one more argument.
3014 * w32.c (emacs_gnutls_pull): Call select with one more argument.
3016 * sysselect.h [DOS_NT]: Don't include sys/select.h.
3017 (pselect) [!MS_DOS]: Redirect to sys_select.
3019 * sysdep.c: Don't include dos.h and dosfns.h.
3021 * process.c (sys_select):
3022 * msdos.c (sys_select): Accept one more argument and ignore it.
3024 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
3025 adapt data types and code to that.
3028 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
3029 which clashes with the gnulib function of the same name.
3031 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3033 * font.c (font_style_to_value, font_style_symbolic)
3034 (font_prop_validate_style): Add type checks for values in
3037 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3039 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3042 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3044 * xdisp.c (try_window_id): Undo last change.
3046 * w32.c (getwd): Adjust commentary about startup_dir.
3047 (init_environment): Always call sys_access, even in non-MSVC
3048 builds. Don't chdir to the directory of the Emacs executable.
3049 This undoes code from 1997 which was justified by the need to
3050 "avoid conflicts when removing and renaming directories". But its
3051 downside was that every relative file name was being interpreted
3052 relative to the directory of the Emacs executable, which can never
3053 be TRT. In particular, it broke sys_access when called with
3054 relative file names.
3055 (sys_access): Map GetLastError to errno.
3057 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3059 * window.h (struct window): Change type of 'fringes_outside_margins'

3063 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3066 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

3069 Add QUIT to make the loop interruptible.
3071 2012-06-29 Glenn Morris <rgm@gnu.org>
3073 * charset.c (init_charset): Make lack of etc/charsets fatal.
3075 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3077 * editfns.c (region_limit): Fix type mismatch.
3079 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3081 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3082 undefined. Convert from xassert to eassert.
3083 * nsmenu.m: Convert from xassert to eassert.
3084 * nsterm.m: Likewise.
3086 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3088 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3090 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3092 Avoid integer overflow on scroll-left and scroll-right.
3093 * window.c (HSCROLL_MAX): New macro.
3094 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3095 overflow when requested scroll falls outside ptrdiff_t range.
3097 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3099 * window.h (struct window): Change type of 'hscroll',
3100 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3101 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3102 Adjust users accordingly.
3103 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3104 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3105 from EMACS_INT to ptrdiff_t.
3106 (make_window): Omit redundant initialization.
3108 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
3110 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
3112 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3114 * window.h (struct window): Change type of 'use_time' and
3115 'sequence_number' from Lisp_Object to int.
3116 * frame.c (make_frame): Adjust users accordingly.

3125 Fix GLYPH_DEBUG usage assuming that it may be undefined,
3126 adjust comments accordingly.

3181 * alloc.c (allocate_string): Omit intervals initialization.
3182 * alloc.c (make_uninit_multibyte_string): Initialize intervals
3183 as in make_pure_string and make_pure_c_string.
3185 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

3239 * alloc.c: Remove build_string.
3240 * lisp.h: Define build_string as static inline. This provides
3241 a better opportunity to optimize away calls to strlen when the
3242 function is called with compile-time constant argument.
3243 * image.c (imagemagick_error): Convert to build_string.
3244 * w32proc.c (sys_spawnve): Likewise.
3245 * xterm.c (x_term_init): Likewise.
3247 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3249 Use sprintf return value instead of invoking strlen on result.
3250 In the old days this wasn't portable, since some sprintf
3251 implementations returned char *. But they died out years ago and
3252 Emacs already assumes sprintf returns int.
3253 Similarly for float_to_string.
3254 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
3255 * ccl.c (ccl_driver):
3256 * character.c (string_escape_byte8):
3257 * data.c (Fnumber_to_string):

3259 * print.c (print_object):
3260 * xdisp.c (message_dolog):
3261 * xfns.c (syms_of_xfns):
3262 Use sprintf or float_to_string result to avoid need to call strlen.
3263 * data.c (Fnumber_to_string):
3264 Use make_unibyte_string, since the string must be ASCII.
3265 * lisp.h, print.c (float_to_string): Now returns int length.
3266 * term.c (produce_glyphless_glyph):
3267 Use sprintf result rather than recomputing it.
3269 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3270 * Makefile.in (ALL_CFLAGS):
3271 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
3272 * gmalloc.c, regex.c: Include <config.h> unconditionally.
3274 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3276 * dispextern.h (xstrcasecmp): Define to library function
3277 strcasecmp if available.
3278 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
3280 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

3293 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
3295 * gtkutil.c (get_utf8_string): Remove redundant assignment.
3296 sprintf already null-terminates its output.
3298 * xfns.c (x_window): Remove redundant cast.
3300 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3302 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
3303 `const char *' to `char *' to avoid compiler warning.
3305 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3307 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
3308 instead of truncating it to 63 (admittedly a generous limit).
3310 * process.c: Fix spelling and caps in comments.
3312 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
3314 * emacs.c (setpgrp): Remove definition, unused.

3358 Use _Noreturn rather than NO_RETURN.
3359 No need for separate decl merely because of _Noreturn.
3360 * sound.c (sound_warning, parse_sound):
3361 Remove unnecessary forward decls.
3363 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3365 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
3366 * lisp.h (WAIT_READING_MAX): New macro.
3367 * dispnew.c (Fsleep_for, sit_for):
3368 * keyboard.c (kbd_buffer_get_event):
3369 * process.c (Faccept_process_output):
3370 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3371 This improves on the previous patch, which introduced a bug
3372 when time_t is unsigned and as wide as intmax_t.
3373 See <http://bugs.gnu.org/9000#51>.
3375 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3377 * dispnew.c (sit_for, Fsleep_for):
3378 * keyboard.c (kbd_buffer_get_event):

3391 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
3392 Privately reported by Herbert J. Skuhra.
3393 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
3395 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
3396 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3398 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3400 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
3401 last argument of make_unibyte_string.
3403 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
3404 language ID in the event parameters.
3406 * w32term.c (w32_read_socket): Put the new keyboard codepage into
3407 event.code, not the obscure "character set ID".

3430 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
3431 Privately reported by Herbert J. Skuhra.
3432 [__FreeBSD__]: Remove "*/" typo after "#include".

3434 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
3435 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
3436 Don't assume EMACS_TIME and struct timeval are the same type.
3438 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3440 Support higher-resolution time stamps (Bug#9000).
3441 The time stamps are only nanosecond-resolution at the C level,
3442 since that's the best that any real-world system supports now.
3443 But they are picosecond-resolution at the Lisp level, as that's
3444 easy, and leaves room for future OS improvements.
3446 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3449 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3450 Don't get current time unless it's needed.
3452 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3453 now provides it if it's absent.
3454 (start_atimer): Port to higher-res time stamps.
3455 Check for time stamp overflow. Don't get current time more
3456 often than is needed.
3458 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3459 Include systime.h, not time.h.
3460 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3462 * dired.c: Include stat-time.h.
3463 (Ffile-attributes): File times now have higher resolution.
3465 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3466 (struct image): Timestamp now has higher resolution.
3468 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3469 has at least microseconds now. All uses removed.
3470 (update_frame, update_single_window, update_window, update_frame_1)
3471 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3472 (duration_to_sec_usec): Remove; no longer needed.
3474 * editfns.c (time_overflow): Now extern.
3475 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3476 (float-time, Fformat_time_string, Fcurrent_time_string)
3477 (Fcurrent_time_zone): Accept and generate higher-resolution
3479 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3480 (decode_time_components, lisp_seconds_argument): New functions.
3481 (make_time): Now static.
3482 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3483 Report an error if the time is invalid, rather than having the caller
3486 * fileio.c: Include <stat-time.h>
3487 (Fcopy_file): Copy higher-resolution time stamps.
3488 Prefer to set the time stamp via a file descriptor if that works.
3489 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3490 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3491 (Fvisited_file_modtime, Fset_visited_file_modtime):
3492 Support higher-resolution time stamps.
3494 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3496 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3498 * image.c (prepare_image_for_display, clear_image_cache)
3499 (lookup_image): Port to higer-resolution time stamps.
3501 * keyboard.c (start_polling, bind_polling_period):
3502 Check for time stamp overflow.
3503 (read_char, kbd_buffer_get_event, timer_start_idle)
3504 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3505 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3506 Port to higher-resolution time stamps. Do not assume time_t is signed.
3507 (decode_timer): New function. Timers are now vectors of length 9,
3508 not 8, to accommodate the picosecond component.
3509 (timer_check_2): Use it.
3511 * nsterm.m (select_timeout, timeval_subtract): Remove.
3512 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3513 as they're a bit more accurate and handle overflow better.
3514 (ns_select): Change prototype to be compatible with pselect.
3515 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3516 * nsterm.h (ns_select): Adjust prototype.
3518 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3519 us-resolution time stamps.
3520 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3522 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3524 * lisp.h (time_overflow): New decl.
3525 (wait_reading_process_output): First arg is now intmax_t, not int,
3526 to accommodate larger waits.
3528 * process.h (struct Lisp_Process.read_output_delay):
3529 Now counts nanoseconds, not microseconds.
3530 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3532 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3533 (wait_reading_process_output):
3534 Port to ns-resolution time stamps.
3535 (Faccept_process_output, wait_reading_process_output):
3536 Check for time stamp overflow. Do not assume time_t is signed.
3537 (select_wrapper): Remove; we now use pselect.
3538 (Fprocess_attributes): Now generates ns-resolution time stamps.
3540 * sysdep.c: Include utimens.h. Don't include utime.h
3541 or worry about struct utimbuf; gnulib does that for us now.
3542 (gettimeofday): Remove; gnulib provides a substitute.
3543 (make_timeval): New function.
3544 (set_file_times): Now sets ns-resolution time stamps.
3545 New arg FD; all uses changed.
3546 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3547 (system_process_attributes):
3548 Now returns ns-resolution time stamp. All uses changed.
3549 Check for time stamp overflow.
3551 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3552 provides a substitute now.
3554 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3555 since it guarantees struct timespec.
3556 (EMACS_TIME): Now struct timespec, so that we can support
3557 ns-resolution time stamps.
3558 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3559 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3560 (EMACS_USECS): Remove.
3561 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3562 so multiply the arg by 1000 before storing it.
3563 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3565 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3566 Port to ns-resolution time stamps.
3567 (EMACS_TIME_NEG_P): Remove; replaced by....
3568 (EMACS_TIME_SIGN): New macro.
3569 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3570 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3571 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3572 (make_timeval, make_lisp_time, decode_time_components): New decls.
3573 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3574 that it mishandled time_t overflow. You can't compare by subtracting!
3575 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3576 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3578 * term.c: Include <sys/time.h>.
3579 (timeval_to_Time): New function, for proper overflow wraparound.
3580 (term_mouse_position, term_mouse_click): Use it.
3582 * undo.c (record_first_change): Support higher-resolution time stamps
3584 (Fprimitive_undo): Use them when restoring time stamps.
3586 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3587 (w32_get_internal_run_time):
3588 Port to higher-resolution Emacs time stamps.
3589 (ltime): Now accepts single 64-bit integer, as that's more convenient
3592 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3594 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3595 for compatibility with pselect. Support ns-resolution time stamps.
3597 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3599 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3600 Check for time stamp overflow, and support ns-resolution time stamps.
3602 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3603 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3604 (timeval_subtract): Remove; no longer needed.
3605 (XTflash, XTring_bell, x_wait_for_event):
3606 Port to ns-resolution time stamps. Don't assume time_t is signed.
3608 2012-06-22 Chong Yidong <cyd@gnu.org>
3610 * xdisp.c (x_consider_frame_title): Revert last change.
3612 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3614 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3615 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3616 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3617 staticidx goes up to 1597 out of 1600 = 0x640.)
3619 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3621 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3622 Otherwise, the umask might be mistakenly 0 while handling input signals.
3624 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3626 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
3628 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>

3631 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
3632 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3633 access to `contents' member of Lisp_Vector objects with AREF and ASET
3636 2012-06-19 Chong Yidong <cyd@gnu.org>
3638 * frame.c (delete_frame): When selecting a frame on a different
3639 text terminal, do not alter the terminal's top-frame.

3642 frame's selected window and its terminal's top-frame.
3643 (unwind_format_mode_line): Restore them.
3644 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3646 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3647 since tty frames can be explicitly named.
3648 (prepare_menu_bars): Likewise.
3650 * term.c (Ftty_top_frame): New function.
3652 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3654 Port byte-code-meter to modern targets.
3655 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3656 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3657 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3658 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3659 (METER_1, METER_2): Simplify.
3661 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3663 * data.c (Fdefalias): Return `symbol' (bug#11686).
3665 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3667 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3668 gets killed during executing of this function (Bug#11665).
3669 Try to always return Qt when the buffer has been actually killed.
3670 (Vkill_buffer_query_functions): In doc-string say that functions
3671 run by this hook should not change the current buffer.
3673 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3675 Fix recently-introduced process.c problems found by static checking.
3676 * process.c (write_queue_push, write_queue_pop, send_process):
3677 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
3678 (write_queue_pop): Fix pointer signedness problem.
3679 (send_process): Remove unused local.
3681 2012-06-17 Chong Yidong <cyd@gnu.org>
3683 * xdisp.c (redisplay_internal): No need to redisplay terminal
3684 frames that are not on top.
3686 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
3688 * process.c (make_process): Initialize write_queue.
3689 (write_queue_push, write_queue_pop): New functions.
3690 (send_process): Use them to maintain correct ordering of process
3693 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3695 * lisp.h (eassert): Assume C89 or later.
3696 This removes the need for CHECK.
3697 (CHECK): Remove. Its comments about always evaluating its

3891 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3892 Use an inline function on all platforms when using the union type,
3893 since this is simpler and 'static inline' can be used portably

4037 * doprnt.c (doprnt): Truncate multibyte char correctly.
4038 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4039 would mishandle a string argument "Xc" if X was a multibyte

4115 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
4116 fields from Lisp_Object to bitfield. Adjust users accordingly.

4124 and 'double' in a couple of places.
4126 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4128 * xdisp.c (handle_stop): Detect whether we have overlay strings
4129 loaded by testing it->current.overlay_string_index to be
4130 non-negative, instead of checking whether n_overlay_strings is
4131 positive. (Bug#11587)

4143 maybe_unify_char, which was the cause of relocation of buffer text
4146 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4148 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4149 for the duration of call to load_charset, to avoid problems with
4150 callers of maybe_unify_char that access buffer text through C
4153 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4154 decrement the inhibition flag, instead of just setting or

4160 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

4164 (gray_bitmap_bits): Remove; no longer needed.

4177 (safe_bcopy): Remove decl; no longer has that name.
4178 (main): Coalesce #if into single bit of code, for simplicity.
4179 Cast pointers to uintptr_t, since standard libraries want integers
4181 * lisp.h (__executable_start): New decl.
4183 2012-05-31 Glenn Morris <rgm@gnu.org>
4185 * image.c (Fimagemagick_types): Doc fix.

4206 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4208 Do not create empty overlays with the evaporate property (Bug#9642).
4209 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4210 Bug#9642, but explicitly check that the buffer the overlay would
4211 be moved to is live and rearrange lines to make sure that errors
4212 will not put the overlay in an inconsistent state.
4213 (Fdelete_overlay): Cosmetics.
4215 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4217 * w32term.c (my_bring_window_to_top): New function.
4218 (x_raise_frame): Use handle returned by DeferWindowPos, which
4219 could be different from the original one.

4223 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4224 by calling BringWindowToTop.
4226 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4227 (WM_EMACS_END): Increase by one.
4229 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4231 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4232 This avoids undefined behavior that might cause the eassert
4233 to not catch an out-of-range value.
4235 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4237 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4238 Update dependencies.
4240 2012-05-27 Eli Zaretskii <eliz@gnu.org>

4247 when referring to sectname field in printf format.
4249 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4251 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4252 Only r_alloc_inhibit_buffer_relocation needed to be added;
4253 the others were already declared.
4255 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4256 before checking whether it's out of range. Put the check inside
4258 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4260 2012-05-27 Ken Brown <kbrown@cornell.edu>
4262 * callproc.c (Fcall_process): Restore a line that was accidentally
4263 commented out in the 2011-02-13 change (bug#11547).
4265 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4267 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4268 defined on ralloc.c.
4270 * buffer.c [REL_ALLOC]: Remove prototypes of
4271 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4272 they are now on lisp.h.
4274 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4276 * search.c (search_buffer): Use it to inhibit relocation of buffer
4277 text while re_search_2 is doing its job, because re_search_2 is
4278 passed C pointers to buffer text. (Bug#11519)
4280 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4283 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4284 state after an additional call to move_it_in_display_line_to, keep
4285 the values of it->max_ascent and it->max_descent found for the
4287 (pos_visible_p): Revert the comparison against bottom_y to what it
4288 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4291 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4293 Fix coding-related core dumps with gcc -ftrapv.
4294 The code was computing A - B, where A and B are pointers, and B is
4295 random garbage. This can lead to core dumps on platforms that
4296 have special pointer registers, and it also leads to core dumps on
4297 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4298 A - B only when B is initialized properly.
4299 * coding.c (coding_set_source, coding_set_destination): Return void.
4300 (coding_change_source, coding_change_destinations): New functions,
4301 with the old behaviors of coding_set_source and coding_set_destination.
4302 All callers that need an offset changed to use these new functions.
4304 2012-05-26 Glenn Morris <rgm@gnu.org>
4306 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4308 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4310 Extend mouse support on W32 text-mode console.
4311 * xdisp.c (draw_row_with_mouse_face):
4312 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4314 * w32console.c: Include window.h.
4315 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4317 (initialize_w32_display): Initialize mouse-highlight data.
4319 * w32inevt.c: Include termchar.h and window.h.
4320 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4321 moves, call note_mouse_highlight. If help_echo changed, call
4322 gen_help_event to produce help-echo message in the echo area.
4323 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4326 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4328 * lread.c (read1): Simplify slightly to avoid an overflow warning
4329 with GCC 4.7.0 on x86-64.
4331 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4333 * bidi.c (bidi_mirror_char): Revert last change: an int is
4334 definitely wide enough here.
4336 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4338 Fix integer width and related bugs (Bug#9874).

4346 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4348 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4349 (allocate_pseudovector):
4350 Use int, not EMACS_INT, where int is wide enough.
4351 (inhibit_garbage_collection, Fgarbage_collect):
4352 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4353 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4354 int might not be wide enough.
4355 (bidi_cache_search, bidi_cache_find, bidi_init_it)

4359 (bidi_level_of_next_char, bidi_move_to_visually_next):
4360 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4361 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4362 (Fkill_buffer, Fset_buffer_major_mode)

4369 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4370 (Foverlay_recenter, last_overlay_modification_hooks_used)
4371 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4372 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4373 (validate_region): Omit unnecessary test for b <= e,
4374 since that's guaranteed by the previous test.
4375 (adjust_overlays_for_delete): Avoid pos + length overflow.
4376 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4377 (report_overlay_modification):
4378 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4379 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4380 Omit pointer cast, which isn't needed anyway, and doesn't work
4381 after the EMACS_INT -> ptrdiff_t change.

4383 * buffer.h: Adjust decls to match defn changes elsewhere.

4387 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
4388 not int, to avoid needless 32-bit limit on 64-bit hosts.
4389 (exec_byte_code): Use tighter memory-full test, one that checks
4390 for alloca overflow. Don't compute the address of the object just
4391 before an array, as that's not portable. Use EMACS_INT, not
4392 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4393 * callint.c (Fcall_interactively):
4394 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4395 * callproc.c (call_process_kill, Fcall_process):

4405 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4406 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4407 (casify_object): Avoid integer overflow when overallocating buffer.
4408 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4409 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4410 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4411 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4412 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4413 integers are now checked earlier. All uses replaced with XINT.
4415 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4416 For CCL_MapSingle, check that content and value are in int range.
4417 (ccl_driver, Fregister_code_conversion_map):
4418 Check that Vcode_version_map_vector is a vector.
4419 (resolve_symbol_ccl_program): Check that vector header is in range.
4420 Always copy the vector, so that we can check its contents reliably
4421 now rather than having to recheck each instruction as it's being
4422 executed. Check that vector words fit in 'int'.
4423 (ccl_get_compiled_code, Fregister_ccl_program)
4424 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4425 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4426 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4427 contents are in range.
4428 (Fccl_execute_on_string): Check that status is in range.
4429 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4430 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4431 Accept and return EMACS_INT, not int, because callers can pass values
4433 (c_string_width, strwidth, lisp_string_width, chars_in_text)

4437 (string_escape_byte8, Fget_byte):
4438 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4439 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4440 avoid mishandling large integers.
4441 * character.h: Adjust decls to match defn changes elsewhere.

4450 (Fdefine_charset_internal): Check ranges here, more carefully.
4451 Don't rely on undefined behavior with signed left shift overflow.
4452 Don't assume unsigned int fits into fixnum, or that fixnum fits
4453 into unsigned int. Don't require max_code to be a valid fixnum;
4454 that's not true for gb10830 4-byte on a 32-bit host. Allow
4455 invalid_code to be a cons, for the same reason. Require code_offset
4456 to be a character. Avoid int overflow if max_char is close
4458 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4459 this is intended anyway and avoids some undefined behavior.
4460 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4461 INDEX_TO_CODE_POINT, as that's what it expects.
4462 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4463 * charset.h (DECODE_CHAR): Return int, not unsigned;
4464 this is what was intended anyway, and it avoids undefined behavior.
4465 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4466 integer-overflow issues.
4467 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4468 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4469 where the argument is EMACS_INT, and this behavior is not intended.
4470 * chartab.c (Fmake_char_table, Fset_char_table_range)
4471 (uniprop_get_decoder, uniprop_get_encoder):
4472 Don't assume fixnum fits in int.
4473 * cmds.c (move_point): New function, that does the gist of
4474 Fforward_char and Fbackward_char, but does so while checking
4475 for integer overflow more accurately.
4476 (Fforward_char, Fbackward_char): Use it.
4477 (Fforward_line, Fend_of_line, internal_self_insert)
4478 (internal_self_insert):
4479 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4480 Fix a FIXME, by checking for integer overflow when calculating
4481 target_clm and actual_clm.

4516 Don't access memory outside of the args array.
4517 (Fdefine_coding_system_internal): Check for charset-id overflow.

4538 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
4539 Do not attempt to compute the address of the object just before a
4540 buffer; this is not portable.

4543 (Faset): Use int, not EMACS_INT, where int is wide enough.
4544 (Fstring_to_number): Don't assume fixnums fit in int.

5298 and right-margin display specs even if the spec is invalid or we
5299 are on a TTY, and thus unable to display on the fringes.
5300 That's because the text with the property will not be displayed anyway,
5301 so we need to signal to the caller that this is a "replacing"
5302 display spec. This fixes display when the spec is invalid or we

5307 * unexaix.c (make_hdr): Fix typo in prototype.
5308 This bug broke the build on AIX. Problem reported by Gilles Pion.
5310 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5312 * keyboard.c (kbd_buffer_get_event): Read special events also in
5313 batch mode. (Bug#11415)
5315 2012-05-12 Glenn Morris <rgm@gnu.org>
5317 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5319 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5321 * lisp.mk (lisp): Add newcomment.elc.
5323 2012-05-12 Glenn Morris <rgm@gnu.org>
5325 * Makefile.in (MKDIR_P): New, set by configure.
5326 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5328 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5330 Remove unused function hourglass_started.
5331 * dispextern.h (hourglass_started):
5332 * w32fns.c (hourglass_started):
5333 * xdisp.c (hourglass_started): Remove.
5335 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5337 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5338 Update dependencies.
5340 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5342 * xgselect.c (xg_select): Put maxfds+1 into a var.
5343 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5345 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5347 2012-05-10 Dave Abrahams <dave@boostpro.com>
5349 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5350 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5352 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5354 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5355 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5356 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5357 Initialize xd_registered_buses.
5359 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5361 Untag more efficiently if USE_LSB_TAG.
5362 This is based on a proposal by YAMAMOTO Mitsuharu in
5363 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5364 For an admittedly artificial (nth 8000 longlist) benchmark on
5365 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5366 Emacs's overall text size by 1%.
5367 * lisp.h (XUNTAG): New macro.
5368 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5369 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5370 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5371 * eval.c (Fautoload):
5372 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5373 * frame.h (XFRAME): Use XUNTAG.
5375 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5376 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5377 Remove unportable assumptions about print widths of types like
5379 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5380 intptr_t when converting between pointer and integer, to avoid GCC
5381 warnings about wrong width.
5383 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5385 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5386 stack for each reader_thread, instead of defaulting to 8MB
5387 determined by the linker. This avoids failures in creating
5388 subprocesses on Windows 7, see the discussion in this thread:
5389 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5391 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5393 Fix up display of the *Minibuf-0* buffer in the mini window.
5394 * keyboard.c (read_char): Don't clear the echo area if there's no
5396 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5397 contents of *Minibuf-0*) if there's no message displayed in its stead.
5399 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5401 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5404 2012-05-06 Chong Yidong <cyd@gnu.org>
5406 * lisp.mk (lisp): Update.
5408 2012-05-05 Jim Meyering <meyering@redhat.com>
5410 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5412 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5414 * data.c (PUT_ERROR): New macro.
5415 (syms_of_data): Use it. Add new error type `user-error'.
5416 * undo.c (user_error): New function.
5417 (Fprimitive_undo): Use it.
5418 * print.c (print_error_message): Adjust print style for `user-error'.
5419 * keyboard.c (user_error): New function.
5420 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5422 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5424 Do not limit current-time-string to years 1000..9999.
5425 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5426 (Fcurrent_time_string): Support any year that is supported by the
5427 underlying localtime representation. Don't use asctime, as it
5428 has undefined behavior for years outside the range -999..9999.
5430 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5432 Fix race conditions involving setenv, gmtime, localtime, asctime.
5433 Without this fix, interrupts could mess up code that uses these
5434 nonreentrant functions, since setting TZ invalidates existing
5435 tm_zone or tzname values, and since most of these functions return
5436 pointers to static storage.
5437 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5438 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5439 Grow the critical sections to include not just invoking
5440 localtime/gmtime, but also accessing these functions' results
5441 including their tm_zone values if any, and any related TZ setting.
5442 (format_time_string): Last arg is now struct tm *, not struct tm **,
5443 so that the struct tm is saved in the critical section.
5444 All callers changed. Simplify allocation of initial buffer, partly
5445 motivated by the fact that memory allocation needs to be outside
5446 the critical section.
5448 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5450 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5451 with RESET_INTERVAL.
5453 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5454 Remove duplicated buffer name initialization.
5456 2012-05-02 Jim Meyering <jim@meyering.net>
5458 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5460 * xfns.c (x_window): Use xstrdup (Bug#11375).
5462 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5464 * xdisp.c (pos_visible_p): If already at a newline from the
5465 display string before the 'while' loop, don't walk back the glyphs
5466 from it3.glyph_row. Solves assertion violation when the display
5467 string begins with a newline (egg.el). (Bug#11367)
5469 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5471 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5474 2012-05-01 Glenn Morris <rgm@gnu.org>
5476 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5477 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5478 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5479 All were removed before 23.1.
5481 * dispnew.c: Remove HAVE_LIBNCURSES test;
5482 it is always true on relevant platforms.
5484 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5485 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5487 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5489 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5491 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5492 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5495 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5497 Do not avoid creating empty evaporating overlays (Bug#9642).
5498 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5499 That is, do not delete an evaporating overlay if it becomes
5500 empty after its bounds are adjusted to fit within its buffer.
5501 This fix caused other problems, and I'm reverting it until we get
5502 to the bottom of them.
5504 2012-04-27 Chong Yidong <cyd@gnu.org>
5506 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5508 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5510 * xdisp.c (pos_visible_p): If the window start position is beyond
5511 ZV, start the display from buffer beginning. Prevents assertion
5512 violation in init_iterator when the minibuffer window is scrolled
5515 * window.c (window_scroll_pixel_based): Likewise.
5517 2012-04-27 Chong Yidong <cyd@gnu.org>
5519 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5521 2012-04-27 Glenn Morris <rgm@gnu.org>
5523 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5524 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5526 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5528 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5529 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5531 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5533 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5534 display element, check also the underlying string or buffer
5535 character. (Bug#11341)
5537 * w32menu.c: Include w32heap.h.
5538 (add_menu_item): If the call to AppendMenuW (via
5539 unicode_append_menu) fails, disable Unicode menus only if we are
5540 running on Windows 9X/Me.
5542 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5544 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5545 (xgetint): Add missing shift for LSB tags.
5547 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5549 * keyboard.c (read_char): Don't wipe echo area for select window
5550 events: These might get delayed via `mouse-autoselect-window'
5553 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5555 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5556 manipulation of :loaded-from data.
5558 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5560 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5561 now a cons (bug#11311).
5563 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5565 Do not create empty overlays with the evaporate property (Bug#9642).
5566 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5567 if it becomes empty after its bounds are adjusted to fit within
5568 its buffer. Without this fix, in a nonempty buffer (let ((o
5569 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5570 yields an empty overlay that has the evaporate property, which is
5571 not supposed to happen.
5573 Fix minor GTK3 problems found by static checking.
5574 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5575 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5576 (struct _EmacsFixedClass, emacs_fixed_get_type):

5584 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5585 (EMACS_FIXED_GET_CLASS): Remove; unused.
5586 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5588 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5589 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5591 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5593 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5594 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5595 (__malloc_size_t, __malloc_ptrdiff_t):
5596 Remove. All uses removed, replaced by the definiens if needed,
5597 since we can assume C89 or better now.
5598 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5599 (protect_malloc_state, align, get_contiguous_space)
5600 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5606 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5607 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5608 Define using prototypes, not old style.
5609 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5610 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5611 (align): Don't assume that signed integer overflow wraps around.
5612 Omit unused local var.
5613 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5614 (_free_internal_nolock, memalign, mallochook, reallochook):
5615 Omit no-longer-needed casts.
5616 (valloc): Use getpagesize, not __getpagesize.

5618 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5620 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5622 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

5673 * alloc.c: Handle unusual debugging option combinations.
5674 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5675 since the two debugging options are incompatible.

5688 * sysdep.c [__FreeBSD__]: Minor cleanups.
5689 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5690 Use Emacs indenting style more consistently. Avoid some casts.
5691 Use 'double' consistently rather than mixing 'float' and 'double'.
5693 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5695 * sysdep.c (list_system_processes, system_process_attributes):

5730 row, return zero immediately.
5731 (try_cursor_movement): If inside continuation line, don't back up
5732 farther than the first row after the header line, if any.
5733 Don't consider the header-line row as "partially visible", even if
5734 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
5736 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5771 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5772 New extern decls, to avoid calling undeclared functions.
5773 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5774 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5775 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5776 (NEED_MEM_INSERT): New macro.
5777 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5778 Remove one incorrect comment and fix another.

5784 (r_alloc_sbrk): Now static.
5786 Improve ralloc.c interface checking.
5787 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

5792 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5793 Remove decls. This fixes an "It stinks!".
5795 * alloc.c (which_symbols): Fix alignment issue / type clash.
5797 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5799 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5812 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5813 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5814 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5815 * s/netbsd.h, s/sol2-6.h:
5816 Remove definition of GC_MARK_STACK, since the default now works.
5817 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5818 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5819 no longer the default.
5820 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5822 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5824 * lread.c (lisp_file_lexically_bound_p):

5845 2012-04-11 Daniel Colascione <dancol@dancol.org>
5847 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5848 against is gone. It's better to use vfork now so that when Cygwin
5849 gains a new, working vfork, we use it automatically (bug#10398).
5851 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5869 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5871 * w32.c (w32_delayed_load): Record the full path of the library
5872 being loaded (bug#10424).
5874 2012-04-09 Glenn Morris <rgm@gnu.org>
5876 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5877 not just in the obarray, before snarfing them. (Bug#11036)
5879 * Makefile.in ($(leimdir)/leim-list.el):
5880 Pass EMACS rather than BUILT_EMACS.

5889 Add convenience `GNUTLS_LOG2i' macro.
5891 * gnutls.c (gnutls_log_function2i): Convenience log function.
5892 (emacs_gnutls_read): Use new log functions,
5893 `gnutls_handshakes_tried' process member, and

5904 * minibuf.c (Fread_variable): Callers changed.
5906 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5908 * xdisp.c (set_cursor_from_row): If the display string appears in
5909 the buffer at position that is closer to point than the position
5910 after the display string, display the cursor on the first glyph of
5911 the display string. Fixes cursor display when a 'display' text
5912 property immediately follows invisible text. (Bug#11094)
5914 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5916 composite.c: use 'double' consistently
5917 * composite.c (get_composition_id): Use 'double' consistently
5918 instead of converting 'float' to 'double' and vice versa; this is
5919 easier to understand and avoids a GCC warning.
5921 2012-04-09 Glenn Morris <rgm@gnu.org>
5923 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5924 preparation for dumping it with emacs. (Bug#4789)

5946 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5947 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5948 objects, as mark_maybe_pointer will catch them otherwise.
5949 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5950 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

5954 Fix typo that broke non-Windows builds.
5955 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5965 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5966 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5967 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5968 [!WINDOWSNT]: New macros.
5969 (init_libxml2_functions, libxml2_loaded_p): New functions.
5970 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5971 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5972 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5973 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5975 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5976 Call init_libxml2_functions before calling libxml2 functions.
5977 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5979 * emacs.c: Don't include libxml/parser.h.
5980 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5981 xmlCleanupParser directly.
5983 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5985 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5987 * indent.c (Fvertical_motion): If there is a display string at
5988 point, use it.vpos to compute how many lines to backtrack after

5993 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5994 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5995 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5996 macros related to unification of CJK characters. For the details,
5997 see the discussion following the message here:
5998 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
6000 2012-04-04 Chong Yidong <cyd@gnu.org>
6002 * keyboard.c (Vdelayed_warnings_list): Doc fix.
6004 2012-04-01 Eli Zaretskii <eliz@gnu.org>
6006 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

6014 2012-03-31 Eli Zaretskii <eliz@gnu.org>
6016 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
6017 position we get to after a call to move_it_to fails the
6018 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
6019 only if we wind up in a string from display property. (Bug#11063)
6021 * window.c (Fdelete_other_windows_internal): Invalidate the row
6022 and column information about mouse highlight, so that redisplay
6023 restores it after reallocating the glyph matrices. (Bug#7464)
6025 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
6026 string comes from a `display' text property, use the buffer
6027 position of that property as if we actually saw that position in
6029 (move_it_by_lines): Remove the assertion that
6030 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6031 violated when there's a before-string at the beginning of a line.
6034 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6036 * xdisp.c (append_space_for_newline): If the default face was
6037 remapped, use the remapped face for the appended newline.
6038 (extend_face_to_end_of_line): Use the remapped default face for
6039 extending the face to the end of the line.
6040 (display_line): Call extend_face_to_end_of_line when the default
6041 face was remapped. (Bug#11068)
6043 2012-03-29 Eli Zaretskii <eliz@gnu.org>
6045 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

6073 * dispextern.h (struct glyph): Change the bit length of
6074 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6076 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6078 * s/ms-w32.h (tzname): Include time.h before redirecting to
6079 _tzname. Fixes the MSVC build. (Bug#9960)
6081 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
6083 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6086 * xterm.c (XTread_socket): Only modify handling_signal if
6087 !SYNC_INPUT. (Bug#11080)
6089 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6091 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6092 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6093 when fetching a multibyte character consumes more bytes than
6094 CHAR_BYTES returns, due to unification of CJK characters in
6095 string_char. (Bug#11073)
6097 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6099 * process.c (wait_reading_process_output): Handle pty disconnect

6133 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6134 that is not from display property, accept the row as a "cursor
6135 row" if one of the string's character has a non-nil `cursor'
6136 property. Fixes cursor positioning when there are newlines in
6137 overlay strings, e.g. in icomplete.el. (Bug#11035)
6139 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

6145 * eval.c (inhibit_lisp_code): Rename from
6146 inhibit_window_configuration_change_hook; move from window.c.
6148 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6149 * window.c (run_window_configuration_change_hook)
6150 (syms_of_window): Callers changed.
6152 2012-03-11 Chong Yidong <cyd@gnu.org>

6165 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6167 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6169 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6170 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6173 2012-03-03 Glenn Morris <rgm@gnu.org>
6175 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6177 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6179 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6180 position past the first glyph_row that ends at ZV. (Bug#10902)
6181 (redisplay_window, next_element_from_string): Fix typos in
6183 (redisplay_window): Pass to move_it_vertically the margin in
6184 pixels, not in screen lines.
6186 2012-03-02 Glenn Morris <rgm@gnu.org>
6188 * buffer.c (buffer-list-update-hook): Doc fix.
6190 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6192 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6193 push_it before setting up the iterator for the first overlay
6194 string, even if we have an empty string loaded.
6195 (next_overlay_string): If there's an empty string on the iterator
6196 stack, pop the stack. (Bug#10903)
6198 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6200 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6201 Suggested by Stefan Monnier in
6202 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6203 * alloc.c (widen_to_Lisp_Object): New static function.
6204 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6205 and widening them to Lisp_Objects. This would work even if
6206 USE_LSB_TAG is defined and wide integers are used, which might
6207 happen in a future version of Emacs.
6209 2012-02-25 Chong Yidong <cyd@gnu.org>
6211 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6214 * xselect.c (Fx_selection_exists_p): Doc fix.
6215 (x_clipboard_manager_save_all): Print an informative message
6216 before saving to clipboard manager.
6218 2012-02-24 Chong Yidong <cyd@gnu.org>

6247 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
6248 when computing $valmask.
6250 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6251 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6252 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6253 It's useless in that case, and it can cause problems on hosts
6254 that allocate halves of EMACS_INT values separately.
6255 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6256 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6257 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6258 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6259 it avoids undefined behavior on hosts where shifting right by more
6260 than the word width has undefined behavior.

6386 * character.c (char_width): Return EMACS_INT, not int.
6387 (char_width, c_string_width): Check for overflow when
6388 computing the width; this is possible now that individual
6389 characters can have unbounded width. Problem introduced

7048 to 4 (xorl, subq, cmpq, setbe).
7049 * alloc.c (pure): Always extern now, since that's the

7062 behave as if the cursor position were at the window margin.
7064 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7065 and the cursor position is out of bounds, behave as if the cursor

7096 * dispnew.c (verify_row_hash): Call row_hash for computing the
7097 hash code of a row, instead of duplicating code from xdisp.c.
7099 * dispextern.h (row_hash): Add prototype.
7101 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
7103 * frame.c (delete_frame): Don't delete the terminal when the last

7241 of temacs in GUI mode.
7243 2011-11-07 Martin Rudalics <rudalics@gmx.at>
7245 * window.h: Declare delete_all_child_windows instead of

7258 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
7259 This is also needed for porting to any host where GC_MARK_STACK is
7260 not GC_MAKE_GCPROS_NOOPS.
7261 (which_symbols): Use it.
7263 2011-11-07 Kenichi Handa <handa@m17n.org>
7265 * coding.c (coding_set_destination): Check coding->src_pos only

7276 * xmenu.c (cleanup_widget_value_tree): New function.
7277 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

7280 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
7282 Fix some portability problems with 'inline'.
7283 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
7284 (window_box_width, window_box_left, window_box_left_offset)
7285 (window_box_right, window_box_right_offset): Declare extern.
7286 Otherwise, these inline functions do not conform to C99 and
7287 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7288 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7289 * intervals.c (adjust_intervals_for_insertion)
7290 (adjust_intervals_for_deletion): Now extern, because otherwise the
7291 extern inline functions 'offset_intervals' couldn't refer to it.
7292 (static_offset_intervals): Remove.
7293 (offset_intervals): Rewrite using the old contents of
7294 static_offset_intervals. The old version didn't conform to C99
7295 because an extern inline function contained a reference to an
7296 identifier with static linkage.
7298 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
7300 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

7318 (Fwindow_vscroll): Doc fix.
7319 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
7320 argument, since it makes no sense to pass a live window and for
7321 consistency with window-child.

7351 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
7352 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
7353 Move terminal->reference_count++ just before making the frame official

7402 * xdisp.c (note_mouse_highlight): If either of
7403 previous/next-single-property-change returns nil, treat that as

7432 Rename cover_string to disp_string.
7434 2011-11-01 Martin Rudalics <rudalics@gmx.at>

7465 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
7467 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
7468 so that this new function doesn't get optimized away by a
7469 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
7471 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
7473 * frame.h (MOUSE_HL_INFO): Remove excess parens.

7496 2011-10-28 Eli Zaretskii <eliz@gnu.org>
7498 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

7500 condition to clear the mouse face.
7502 2011-10-28 Chong Yidong <cyd@gnu.org>

7529 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
7531 (w32font_open_internal, compute_metrics):
7532 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7533 instead of calling the "wide" APIs directly.
7535 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
7537 * w32.h (syms_of_w32font): Add prototype.
7539 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

7543 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

7548 * process.c (make_process): Set gnutls_state to NULL.
7550 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
7551 non-NULL, regardless of GNUTLS_INITSTAGE.
7552 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7553 an error. Set process slots as soon as we allocate them.

7599 current character, check also for next_en_type being WEAK_EN.
7600 (bidi_resolve_weak): Don't enter the expensive loop if the current
7601 position is before next_en_pos. Record the bidi type of the first
7602 non-ET, non-BN character we find, in addition to its position.
7603 (bidi_level_of_next_char): Invalidate next_en_type when
7604 next_en_pos is over-stepped.
7606 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7608 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7609 * editfns.c: Rewrite current-time-zone so that it invokes
7610 the equivalent of (format-time-string "%Z") to get the time zone name.
7611 This fixes a bug when the time zone name contains characters that
7612 need converting from the system time locale to Emacs internal format.
7613 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7614 that patch fixed format-time-string to do the conversion, but
7615 I forgot to fix current-time-zone.
7616 (format_time_string): New function, containing most of
7617 what Fformat_time_string used to contain.
7618 (Fformat_time_string): Rewrite in terms of format_time_string.
7619 This doesn't change this function's behavior.
7620 (current-time-zone): Rewrite to use format_time_string.
7621 This fixes the bug reported by Michael Schierl in
7622 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7623 Jason Rumney's 2007-06-07 change worked around this bug, but
7625 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7627 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7629 * xdisp.c (start_display): If the character at POS is displayed
7630 via a display vector, reset IT->current.dpvec_index to zero.
7631 (try_window_reusing_current_matrix): If a line ends in a display
7632 vector or the next line starts in a display vector, continue
7633 redrawing the window even though the character position of
7634 start_row was reached.
7637 2011-10-18 Chong Yidong <cyd@gnu.org>
7639 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7640 with nobreak-char-display too.
7642 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7644 Fix part 3 of bug#9771.
7645 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7646 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7647 non-neutral characters if the current character is a paragraph
7648 separator (a.k.a. Newline). This avoids running the same
7649 expensive loop twice, once when we consume the preceding newline
7650 and the other time when the line actually needs to be displayed.
7651 Avoid the loop when we see neutrals on the base embedding level
7652 following a character whose directionality is the same as the
7653 paragraph's. This avoids running the expensive loop when a line
7654 ends in a long sequence of neutrals, like control characters.
7655 Add assertion against STRONG_AL type. Slightly rearrange code
7656 that determines the type of a neutral given the first non-neutral
7658 (bidi_level_of_next_char): Set next_en_pos to zero when
7659 invalidating its info.
7661 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7663 * xdisp.c (push_display_prop): Determine whether to record string
7664 or buffer position by IT->string, not by IT->method. Allow
7665 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7666 (move_it_vertically_backward): Don't look for character position
7667 immediately after the newline when in a continuation line.
7670 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7672 * window.c (coordinates_in_window): Rewrite and delabelize
7673 vertical border check. (Bug#5357) (Bug#9618)
7675 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7677 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7678 errors in XSetWindowBorder (bug#9310).
7680 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7682 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7683 avoid crash when xmalloc overrun checking is enabled.
7685 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7687 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7688 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7689 cursor motion with <left> and <right> arrow keys.
7691 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7692 some callers set that themselves.
7694 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7696 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7697 display string and the previous row comes from the same string and
7698 is empty. (Bug#9739) (Bug#9738)
7700 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7702 * doc.c (get_doc_string): Encode file name (bug#9735).
7704 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7706 * bidi.c (bidi_level_of_next_char):
7707 * xdisp.c (get_visually_first_element): Remove old incorrect
7708 comments regarding the Unicode Line Separator character.
7710 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7712 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7714 * alloc.c (Fgc_status): Do not access beyond zombies array
7715 boundary if nzombies > MAX_ZOMBIES.
7716 * alloc.c (dump_zombies): Add missing format specifier.
7718 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7720 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7721 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7723 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7724 Some packages use them to denote characters with modifiers.
7726 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7728 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7729 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7730 matching a pp-number. Rename parameter var to var1.
7732 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7734 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7736 2011-10-08 Glenn Morris <rgm@gnu.org>
7738 * callint.c (Fcall_interactively): Give a more explicit error for the
7739 'c' case with a non-character input. (Bug#8479)
7741 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7743 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7745 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7746 lines that are hscrolled on the left.
7748 * dispnew.c (buffer_posn_from_coords): Account for a possible
7749 presence of header-line. (Bug#4426)
7751 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7753 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7754 Don't advertise functionality which we discourage or doesn't work.
7756 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7758 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7759 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7760 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7761 this makes Emacs dump core during garbage collection on rare
7762 occasions. sizeof is obviously inferior to offsetof here, so
7763 stick with offsetof.
7764 (GC_POINTER_ALIGNMENT): New macro.
7765 (mark_memory): Omit 3rd (offset) arg; caller changed.
7766 Don't assume EMACS_INT alignment is the same as pointer alignment.
7768 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7770 * keyboard.c (read_key_sequence_remapped): New var.
7771 (read_key_sequence): Compute remapping in the right buffer.
7772 (command_loop_1): Use read_key_sequence's remapping directly.
7774 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7776 * dired.c (file_name_completion): Don't expand file name.
7777 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7778 before checking file name handler.
7780 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7781 they've been requested explicitly (bug#9591).
7783 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7785 * keymap.c (Fsingle_key_description): Use make_specified_string
7786 instead of build_string to build string from push_key_description.
7789 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7791 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7792 This fixes a Y2038 bug on 64-bit hosts.
7793 * buffer.c (reset_buffer):
7794 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7795 (Fclear_buffer_auto_save_failure):
7796 Use 0, not -1, to represent an unset failure time, since time_t
7797 might not be signed.
7799 Remove dependency on glibc malloc internals.
7800 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7801 Move back here from lisp.h, but with their new implementations.
7802 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7803 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7804 * charset.c (charset_table_init): New static var.
7805 (syms_of_charset): Use it instead of xmalloc. This removes a
7806 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7807 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7808 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7809 Move back to alloc.c.
7810 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7811 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7813 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7815 * nsterm.m (windowDidResize): Call x_set_window_size only when
7816 ns_in_resize is true. Otherwise set pixelwidth/height and
7817 call change_frame_size (Bug#9628).
7819 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7821 Port --enable-checking=all to Fedora 14 x86-64.
7822 * charset.c (syms_of_charset): Also account for glibc malloc's
7823 internal overhead when calculating the initial malloc maximum.
7825 Port --enable-checking=all to Fedora 14 x86.
7826 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7828 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7829 (overrun_check_realloc, overrun_check_free):
7830 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7831 That way, xmalloc returns a properly-aligned pointer even if
7832 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7833 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7834 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7835 into account when calculating the initial malloc maximum.
7836 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7837 Move here from alloc.c, so that charset.c can use it too.
7838 Properly align; the old code wasn't right for common 32-bit hosts
7839 when configured with --enable-checking=all.
7840 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7841 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7843 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7845 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7848 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7850 * xdisp.c (compute_display_string_end): If there's no display
7851 string at CHARPOS, return -1.
7853 * bidi.c (bidi_fetch_char): When compute_display_string_end
7854 returns a negative value, treat the character as a normal
7855 character not covered by a display string. (Bug#9624)
7857 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7859 * lread.c (Fread_from_string): Fix typo in docstring.
7861 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7863 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7864 newline, reseat the iterator instead of bidi-iterating there one
7865 character at a time. (Bug#9610)
7866 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7867 TO_CHARPOS if the bidi iterator is at base embedding level.
7869 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7871 * lread.c (readevalloop): Use correct code for NBSP.
7872 (read1): Likewise. (Bug#9608)
7874 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7876 * dbusbind.c (Fdbus_register_signal): When service is not
7877 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7879 2011-09-25 Glenn Morris <rgm@gnu.org>
7881 * buffer.c (truncate-lines): Doc fix.
7883 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7885 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7886 (Fset_window_next_buffers): Doc fix.
7888 2011-09-24 Glenn Morris <rgm@gnu.org>
7890 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7892 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7894 Fix minor problems found by static checking.
7895 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7896 * indent.c (Fvertical_motion): Fix == vs = typo.
7898 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7900 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7901 Default value is now t. Doc fix.
7903 * indent.c (Fvertical_motion): Compute and apply the overshoot
7904 logic when moving up, not only when moving down. Fix the
7905 confusing name and values of the it_overshoot_expected variable;
7906 logic changes accordingly. (Bug#9254) (Bug#9549)
7908 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7909 CHARPOS is covered by a display string which includes newlines.
7910 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7911 is covered by a display string with embedded newlines.
7913 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7915 * dbusbind.c (Fdbus_register_signal): Add match rule to
7916 Vdbus_registered_objects_table. (Bug#9581)
7917 (Fdbus_register_method, Vdbus_registered_objects_table):
7920 2011-09-24 Jim Meyering <meyering@redhat.com>
7922 do not ignore write error for any output size
7923 The previous change was incomplete.
7924 While it makes emacs --batch detect the vast majority of stdout
7925 write failures, errors were still ignored whenever the output size is
7926 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7927 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7928 && echo FAIL: ignored write error
7929 FAIL: ignored write error
7930 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7931 && echo FAIL: ignored write error
7932 FAIL: ignored write error
7933 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7935 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7937 * emacs.c (Fkill_emacs): In noninteractive mode exit
7938 non-successfully if a write error occurred on stdout. (Bug#9574)
7940 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7942 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7945 * dispextern.h (struct it): Update the comment documenting what
7948 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7950 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7951 a display string, extend search for cursor position to end of row.
7952 (find_row_edges): If the row ends in a newline from a display
7953 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7954 Handle the case of a display string with multiple newlines.
7955 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7956 non-empty line. Fixes confusing cursor motion with arrow keys at
7957 the beginning of a line that starts with whitespace.
7959 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7961 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7964 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7966 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7969 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7971 * xdisp.c (display_line): Record maximum and minimum buffer
7972 positions even if no glyphs were produced (e.g., by a zero-width
7973 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7974 buffer positions that will be removed from the glyph row because
7976 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7977 column is beyond frame width: don't subtract 1 "pixel" when
7978 computing width of the stretch.
7979 (reseat_at_next_visible_line_start): Undo the change made on
7980 2011-09-17 that saved paragraph information and restored it after
7981 the call to `reseat'. (Bug#9545)
7983 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7985 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7986 and turn window cursor on if cleared (Bug#9415).
7988 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7990 * search.c (boyer_moore): Take unibyte characters from pattern
7991 literally. (Bug#9458)
7993 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7995 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7997 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7999 Fix minor problem found by static checking.
8000 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
8001 initialized, to pacify gcc -Wuninitialized.
8003 * fileio.c: Report proper errno when syscall falls.
8004 (Finsert_file_contents): Save and restore errno,
8005 so that report_file_error outputs the correct diagnostic.
8006 (Fwrite_region) [CLASH_DETECTION]: Likewise.
8008 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8010 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
8012 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8014 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
8015 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
8017 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8019 * xdisp.c (reseat_at_next_visible_line_start): Keep information
8020 about the current paragraph and restore it after the call to reseat.
8022 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
8023 (bidi_find_paragraph_start): Search back for paragraph beginning
8024 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
8025 (bidi_move_to_visually_next): Only trigger paragraph-related
8026 computations when the last character is a newline or at EOB, not
8027 just any NEUTRAL_B. (Bug#9470)
8029 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
8030 truncated lines if point is covered by a display string. (Bug#9524)
8032 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
8034 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8035 (cons_to_x_long): New function.
8036 (lisp_data_to_selection_data): Use it. Correct the test for
8037 short-versus-long data; it was negated. Break out of vector
8038 loop, for efficiency, when a long datum is discovered.
8040 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8042 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8044 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8046 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
8047 GCC PR/17406) by declaring this function with external scope.
8049 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8051 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
8052 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
8054 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
8056 * editfns.c (Fformat): Correctly handle text properties on "%%".
8058 2011-09-15 Eli Zaretskii <eliz@gnu.org>
8060 * xterm.c (x_draw_composite_glyph_string_foreground):
8061 * w32term.c (x_draw_composite_glyph_string_foreground):
8062 * term.c (encode_terminal_code):
8063 * composite.c (composition_update_it, get_composition_id):
8064 * xdisp.c (get_next_display_element)
8065 (fill_composite_glyph_string): Add comments about special meaning
8066 of TAB characters in a composition.
8068 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8070 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8071 This occurs when processing a multibyte format.
8072 Problem reported by Wolfgang Jenker.
8074 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8076 * xdisp.c (try_cursor_movement): Only check for exact match if
8077 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8079 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8081 Remove unused external symbols.
8082 * dispextern.h (calc_pixel_width_or_height): Remove decl.
8083 * xdisp.c (calc_pixel_width_or_height): Now static.
8084 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
8085 * indent.c (check_display_width):
8086 * w32term.c: Fix comment to match code.
8087 * xterm.c, xterm.h (x_catching_errors): Remove.
8089 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8091 * xselect.c: Use signed conversions more consistently (Bug#9498).
8092 (selection_data_to_lisp_data): Assume incoming selection data are
8093 signed integers, not unsigned. This is to be consistent with
8094 outgoing selection data, which was modified to use signed integers
8095 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8096 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8097 expects long, not unsigned long.
8099 2011-09-14 Eli Zaretskii <eliz@gnu.org>
8101 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
8102 computation of loop end. Reported by Johan Bockgård
8105 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
8107 * frame.c (Fother_visible_frames_p): Function deleted.
8109 2011-09-12 Eli Zaretskii <eliz@gnu.org>
8111 * indent.c (compute_motion): Process display vector front to back
8112 rather than the other way around. (Bug#2496)
8114 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
8116 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
8118 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
8120 * minibuf.c (Fread_from_minibuffer): Doc fix.
8122 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8124 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8125 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8127 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8129 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8130 value for non-existent files.
8132 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8134 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8135 set its "size" to -1. This will set the modtime_size field of
8136 the corresponding buffer to -1, which is what
8137 verify-visited-file-modtime expects for files that do not exist.
8140 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8142 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8144 * lisp.h: ... from here. push_key_description is no longer
8145 defined in keyboard.c, so its declaration should not be in
8146 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8147 logically belongs with push_key_description.
8149 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8151 * buffer.h: Include <sys/types.h> instead of <time.h>.
8152 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8153 Problem reported by Herbert J. Skuhra.
8155 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8157 * xml.c (parse_region): Make the parsing work for
8158 non-comment-starting XML files again (bug#9144).
8160 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8162 * image.c (gif_load): Fix calculation of bottom and right corner.
8165 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8167 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8168 redisplay in small windows.
8170 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8172 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8174 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8176 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8177 Operate on live windows only.
8179 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8181 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8183 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8185 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8186 only under bidi iteration.
8188 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8190 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8192 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8194 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8195 Without this fix, the command to link temacs failed due to an
8196 undefined symbol __builtin_isnan. This is because
8197 /usr/include/iso/math_c99.h #defines isnan(x) to
8198 __builtin_isnan(x), but the bundled gcc, which identifies itself
8199 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8201 * floatfns.c (isnan): #undef, and then #define to a clone of
8203 (Fisnan): Always define, since it's always available now.
8204 (syms_of_floatfns): Always define isnan at the Lisp level.
8206 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8208 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8210 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8212 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8213 The previous code assumed that file offsets (off_t values) fit in
8214 EMACS_INT variables, which is not true on typical 32-bit hosts.
8215 The code messed up by falsely reporting buffer overflow in cases
8216 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8217 when "big" contains more than 2**29 bytes, even though this
8218 inserts just one byte and does not overflow the buffer.
8219 (Finsert_file_contents): Store file offsets as off_t
8220 values, not as EMACS_INT values. Check for overflow when
8221 converting between EMACS_INT and off_t. When checking for
8222 buffer overflow or for overlap, take the offsets into account.
8223 Don't use EMACS_INT for small values where int suffices.
8224 When checking for overlap, fix a typo: ZV was used where
8225 ZV_BYTE was intended.
8226 (Fwrite_region): Don't assume off_t fits into 'long'.
8227 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8229 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8231 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8233 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8235 sprintf-related integer and memory overflow issues (Bug#9412).
8237 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8238 (esprintf, exprintf, evxprintf): New functions.
8239 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8240 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8241 (modify_event_symbol): Do not assume that the length of
8242 name_alist_or_stem is safe to alloca and fits in int.
8243 (Fexecute_extended_command): Likewise for function name and binding.
8244 (Frecursion_depth): Wrap around reliably on integer overflow.
8245 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8246 since some callers pass EMACS_INT values.
8247 (Fsingle_key_description): Don't crash if symbol name contains more
8248 than MAX_ALLOCA bytes.
8249 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8250 (get_minibuffer): Arg is now EMACS_INT, not int.
8251 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8252 (esprintf, exprintf, evxprintf): New decls.
8253 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8255 * dbusbind.c (signature_cat): New function.
8256 (xd_signature, Fdbus_register_signal):
8257 Do not overrun buffer; instead, report string overflow.
8259 * dispnew.c (add_window_display_history): Don't overrun buffer.
8260 Truncate instead; this is OK since it's just a log.
8262 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8263 even if the time zone offset is outlandishly large.
8264 Don't mishandle offset == INT_MIN.
8266 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8267 when creating daemon; the previous buffer-overflow check was incorrect.
8269 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8270 which has the guts of the old verror function.
8272 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8273 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8275 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8276 (font_unparse_xlfd): Don't blindly alloca long strings.
8277 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8278 fits in int, when using sprintf. Use single snprintf to count
8279 length of string rather than counting it via multiple sprintfs;
8280 that's simpler and more reliable.
8281 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8282 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8283 sprintf, in case result does not fit in int.
8285 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8286 (fontset_from_font): Print it.
8288 * frame.c (tty_frame_count): Now printmax_t, not int.
8289 (make_terminal_frame, set_term_frame_name): Print it.
8290 (x_report_frame_params): In X, window IDs are unsigned long,
8291 not signed long, so print them as unsigned.
8292 (validate_x_resource_name): Check for implausibly long names,
8293 and don't assume name length fits in 'int'.
8294 (x_get_resource_string): Don't blindly alloca invocation name;
8295 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8298 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8299 (xg_check_special_colors, xg_set_geometry):
8300 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8302 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8303 Use esprintf, not sprintf, in case result does not fit in int.
8305 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8306 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8307 it as a large positive number.
8308 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8309 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8311 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8312 in case result does not fit in int.
8314 * print.c (float_to_string): Detect width overflow more reliably.
8315 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8316 buffer overrun. Don't assume list length fits in 'int'. Treat
8317 print length of 0 as 0, not as infinity; to be consistent with other
8318 uses of print length in this function. Don't overflow print length
8319 index. Don't assume hash table size fits in 'long', or that
8320 vectorlike size fits in 'unsigned long'.
8322 * process.c (make_process): Use printmax_t, not int, to format
8323 process-name gensyms.
8325 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8327 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8328 to avoid potential buffer overrun.
8330 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8331 if X resource line is longer than 512 bytes.
8333 * xfns.c (x_window): Make sprintf buffer a bit bigger
8334 to avoid potential buffer overrun.
8336 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8338 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8340 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8342 Integer overflow fixes for scrolling, etc.
8343 Without these, Emacs silently mishandles large integers sometimes.
8344 For example, "C-u 4294967297 M-x recenter" was treated as if
8345 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8347 * xdisp.c (try_window_id): Check Emacs fixnum range before
8348 converting to 'int'.
8350 * window.c (window_scroll_line_based, Frecenter):
8351 Check that an Emacs fixnum is in range before assigning it to 'int'.
8352 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8353 values converted from Emacs fixnums.
8354 (Frecenter): Don't wrap around a line count if it is out of 'int'
8355 range; instead, treat it as an extreme value.
8356 (Fset_window_configuration, compare_window_configurations):
8357 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8359 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8360 that can exceed INT_MAX. Check that EMACS_INT value is in range
8361 before assigning it to the (possibly-narrower) index.
8362 (match_limit): Don't assume that a fixnum can fit in 'int'.
8364 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8367 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8368 (Fvertical_motion): Don't wrap around LINES values that don't fit
8369 in 'int'. Instead, treat them as extreme values. This is good
8370 enough for windows, which can't have more than INT_MAX lines anyway.
8372 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8374 * Require libxml/parser.h to avoid compilation warning.
8376 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8378 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8379 since this reportedly can destroy thread storage.
8381 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8383 * syntax.c (find_defun_start): Update all cache variables if
8384 exiting early (Bug#9401).
8386 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8388 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8390 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8391 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8392 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8394 * term.c (tty_append_glyph): New function.
8395 (produce_stretch_glyph): Static function and its prototype deleted.
8397 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8400 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8402 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8403 when checking :margin (Bug#9390).
8404 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8405 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8406 so that the name doesn't mislead. All uses changed.
8408 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8410 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8413 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8415 * xdisp.c (move_it_to): Don't bail out early when reaching
8416 position beyond to_charpos, if we are scanning backwards.
8417 (move_it_vertically_backward): When DY == 0, make sure we get to
8418 the first character in the line after the newline.
8420 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8422 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8423 (ccl_driver): Do not generate an out-of-range pointer.
8424 (Fccl_execute_on_string): Remove unnecessary check for
8425 integer overflow, noted by Stefan Monnier in
8426 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8427 Remove a FIXME that didn't need fixing.
8428 Simplify the newly-introduced buffer reallocation code.
8430 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8432 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8434 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8436 Integer and memory overflow issues (Bug#9196).
8438 * doc.c (get_doc_string): Rework so that
8439 get_doc_string_buffer_size is the actual buffer size, rather than
8440 being 1 less than the actual buffer size; this makes xpalloc more
8443 * image.c (x_allocate_bitmap_record, cache_image):
8444 * xselect.c (Fx_register_dnd_atom):
8445 Simplify previous changes by using xpalloc.
8447 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8448 since either will do and ptrdiff_t is convenient with xpalloc.
8450 * charset.c (charset_table_size)
8451 (struct charset_sort_data.priority): Now ptrdiff_t.
8452 (charset_compare): Don't overflow if priorities differ greatly.
8453 (Fsort_charsets): Don't assume list length fits in int.
8454 Check for size-calculation overflow when allocating sort data.
8455 (syms_of_charset): Allocate an initial charset table that is
8456 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8458 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8460 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8461 The actual value is always <= INT_MAX, and leaving it unsigned made
8462 overflow checking harder.
8464 * dispextern.h (struct glyph_matrix.rows_allocated)
8465 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8466 with xpalloc. The values are still always <= INT_MAX.
8468 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8470 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8471 (SAFE_NALLOCA): New macro.
8473 * region-cache.c (struct boundary.pos, find_cache_boundary)
8474 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8475 (set_cache_region, invalidate_region_cache)
8476 (revalidate_region_cache, know_region_cache, region_cache_forward)
8477 (region_cache_backward, pp_cache):
8478 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8479 so that ptrdiff_t * can be passed to xpalloc.
8480 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8481 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8482 (pp_cache): Don't assume cache_len fits in int.
8483 * region-cache.h: Adjust extern decls to match.
8485 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8486 EMACS_INT, since either will do, for xpalloc.
8488 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8489 (xnmalloc, xnrealloc, xpalloc): New functions.
8491 * bidi.c (bidi_shelve_header_size): New constant.
8492 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8493 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8495 * bidi.c (bidi_cache_shrink):
8496 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8498 Don't update size of array until after memory allocation succeeds,
8499 because xmalloc/xrealloc may not return.
8500 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8501 now that we have proper integer overflow checking.
8502 (record_overlay_string, overlay_strings): Catch overflows when
8503 calculating size of overlay_str_buf.
8505 * callproc.c (Fcall_process): Check for size overflow when
8506 calculating size of args2.
8507 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8508 Normally we prefer signed values, but sticking with ptrdiff_t would
8509 require adding more-complicated checks.
8511 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8512 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8513 Redo buffer-overflow calculations to avoid integer overflow.
8514 Add a FIXME comment where memory seems to be over-allocated.
8516 * character.c (Fstring): Check for size-calculation overflow.
8518 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8519 unnecessary integer overflow. Check for size overflow.
8520 (encode_coding_object): Don't update size until xmalloc succeeds.
8522 * composite.c (get_composition_id): Check for overflow in glyph
8523 length calculations.
8525 Integer and memory overflow fixes for display code.
8526 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8527 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8528 (scrolling_window): Check for overflow in size calculations.
8529 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8530 Don't assume glyph table len fits in int.
8531 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8532 (row_table_size): Now ptrdiff_t, not int.
8533 (scrolling_window): Avoid overflow in size calculations.
8534 Don't update size until allocation succeeds.
8535 * fns.c (concat): Check for overflow in size calculations.
8536 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8537 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8538 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8540 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8541 (get_doc_string): Check for size calculation overflow.
8542 Don't update size until allocation succeeds.
8543 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8544 EMACS_INT, where ptrdiff_t will do.
8545 (Fsubstitute_command_keys): Check for string overflow.
8547 * editfns.c (set_time_zone_rule): Don't assume environment length
8549 (message_length): Now ptrdiff_t, not int.
8550 (Fmessage_box): Don't update size until allocation succeeds.
8551 Don't assume message length fits in int.
8552 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8554 * emacs.c (main): Do not reallocate argv, since there is a null at
8555 the end that can be overwritten, and this way there's no need to
8556 worry about size-calculation overflow.
8557 (sort_args): Check for size-calculation overflow.
8559 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8561 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8563 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8564 (x_set_scroll_bar_width, x_figure_window_size):
8565 Check for integer overflow.
8566 (x_set_alpha): Do not assume XINT fits in int.
8568 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8569 This is for the members text_lines, text_cols, total_lines, total_cols,
8570 where the system imposes an 'int' limit.
8572 * fringe.c (Fdefine_fringe_bitmap):
8573 Don't update size until alloc works.
8575 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8576 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8578 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8579 Check for size-calculation overflow.
8580 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8581 do, as we prefer signed integers.
8582 (id_to_widget.max_size, id_to_widget.used)
8583 (xg_store_widget_in_map, xg_remove_widget_from_map)
8584 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8585 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8586 Use and return ptrdiff_t, not int.
8587 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8588 * gtkutil.h: Change prototypes to match the above.
8590 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8591 are duplicate now that they've been promoted to lisp.h.
8592 (x_allocate_bitmap_record, x_alloc_image_color)
8593 (make_image_cache, cache_image, xpm_load):
8594 Don't update size until alloc is done.
8595 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8597 Check for size calculation overflow.
8598 (ct_colors_allocated_max): New constant.
8599 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
8602 * keyboard.c (read_char, menu_bar_items, tool_bar_items)

8604 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8605 Use ptrdiff_t, not int, to count maps.
8606 (read_char_minibuf_menu_prompt): Check for overflow in size
8607 calculations. Don't update size until allocation succeeds.
8608 Redo calculations to avoid overflow.
8609 * keyboard.h: Change prototypes to match the above.
8611 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

8618 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
8619 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8621 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8622 Now ptrdiff_t, not int.
8623 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8624 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
8626 * process.c (Fnetwork_interface_list): Check for overflow
8627 in size calculation.
8629 * region-cache.c (move_cache_gap): Check for size calculation overflow.
8631 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
8632 overflow. Don't bother calling xmalloc when xrealloc will do.
8634 * search.c (Freplace_match): Check for size calculation overflow.
8635 (Fset_match_data): Don't assume list lengths fit in 'int'.
8637 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8638 for command line length. Do not attempt to address one before the
8639 beginning of an array, as that's not portable.
8641 * term.c (max_frame_lines): Remove; unused.
8642 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8644 (encode_terminal_code, calculate_costs): Check for size
8645 calculation overflow.
8646 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
8647 table lengths and related sizes. Don't update size until alloc
8648 done. Redo calculations to avoid overflow.
8649 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8651 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
8652 subtracting pointers.
8653 (gobble_line): Check for overflow more carefully. Don't update size

8667 Use ptrdiff_t, not int, for sizes.
8668 (Finternal_make_lisp_face, cache_face):
8669 Check for size calculation overflow.
8670 (cache_face): Treat size calculation overflows as if they were
8671 memory exhaustion (the usual treatment), rather than aborting.
8673 * xfns.c (x_encode_text, x_set_name_internal)
8674 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8675 sizes, since they can exceed INT_MAX in size. Check for size
8676 calculation overflow.
8678 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8679 (xg_select): Check for size calculation overflow.
8680 Don't update size until alloc done.
8682 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8683 as sprintf is limited to int lengths.
8685 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8686 (X_LONG_MIN): New macros.
8687 Use them to make the following changes clearer.
8688 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8689 This change doesn't affect the value now, but it may help remind
8690 future maintainers not to raise the value too much later.
8691 (SELECTION_QUANTUM): Remove, replacing with ...
8692 (selection_quantum): ... new function, which avoids overflow.
8694 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8695 assumption that selection length fits in 'int'.
8696 (x_reply_selection_request, x_handle_selection_request)
8697 (x_get_window_property, receive_incremental_selection)

8703 Redo calculations to avoid overflow.
8704 (x_reply_selection_request): When sending hint, ceiling it at
8705 X_LONG_MAX rather than relying on wraparound overflow to send

8708 (lisp_data_to_selection_data, x_property_data_to_lisp):
8709 Check for size-calculation overflow.

8712 Don't store size until memory allocation succeeds.
8713 (x_get_window_property): Plug memory leak on memory exhaustion.
8714 Don't double-block input; malloc is safe here. Don't assume 2**34
8715 - 4 fits in unsigned long. Add an xassert to check
8716 XGetWindowProperty overflow. Be more careful about overflow
8717 calculations, and distinguish size from memory overflow better.
8718 (receive_incremental_selection): When tracing, don't assume
8719 unsigned int is less than INT_MAX.
8720 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8721 harmful) conversions of unsigned short to int.
8722 (lisp_data_to_selection_data): Don't assume that integers
8723 in the range -65535 through -1 fit in an X unsigned short.
8724 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8725 result parameters unless successful. Rely on cons_to_unsigned
8726 to report problems with elements; the old code wasn't right anyway.
8727 (x_check_property_data): Check for int overflow; we cannot use
8728 a wider type due to X limits.
8729 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8731 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
8733 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
8734 (x_term_init): Check for size calculation overflow.
8735 (x_color_cells): Don't store size until memory allocation succeeds.

8760 * image.c (xpm_get_color_table_h):
8761 * lisp.h (hash_lookup, hash_put):
8762 * minibuf.c (Ftest_completion):
8763 Use ptrdiff_t for hash table indexes, not int (which is too
8764 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8765 32-bit --with-wide-int hosts).
8767 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8768 Add a FIXME comment about memory leaks.

8773 * character.h (CHAR_WIDTH):
8774 * indent.c (MULTIBYTE_BYTES_WIDTH):
8775 Use sanitize_char_width to avoid undefined and/or bad behavior
8776 with outlandish widths.
8777 * character.h (sanitize_tab_width): Rename from sanitize_width,
8778 now that we have two such functions. All uses changed.
8779 (sanitize_char_width): New inline function.
8781 Don't assume that tab-width fits in int.
8782 * character.h (sanitize_width): New inline function.
8783 (SANE_TAB_WIDTH): New macro.

8797 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8798 (x_send_scroll_bar_event): Likewise. Check that the size does not
8799 exceed limits imposed by XClientMessageEvent, as well as the usual
8800 ptrdiff_t and size_t limits.
8802 * keyboard.c: Overflow, signedness and related fixes.
8803 (make_lispy_movement): Use same integer type in forward decl
8804 that is used in the definition.
8805 (read_key_sequence, keyremap_step):
8806 Change bufsize argument back to int, undoing my 2011-03-30 change.
8807 We prefer signed types, and int is wide enough here.
8808 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8809 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8810 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8811 length, not size_t. Use ptrdiff_t for index, not int.
8812 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8813 possibility of integer overflow.
8815 Overflow, signedness and related fixes for images.

8825 * xdisp.c (calc_pixel_width_or_height):
8826 * xfns.c (image_cache_refcount):
8827 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8828 on typical 64-bit hosts.
8830 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8831 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8836 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8837 (lookup_image): Remove unnecessary tests.
8838 (xbm_image_p): Locals are now of int, not EMACS_INT,
8839 since parse_image_check makes sure they fit into int.
8840 (png_load, gif_load, svg_load_image):
8841 Prefer int to unsigned where either will do.
8842 (tiff_handler): New function, combining the cores of the
8843 old tiff_error_handler and tiff_warning_handler.
8844 This function is rewritten to use vsnprintf and thereby avoid
8845 stack buffer overflows. It uses only the features of vsnprintf
8846 that are common to both POSIX and native Microsoft.
8847 (tiff_error_handler, tiff_warning_handler): Use it.
8848 (tiff_load, gif_load, imagemagick_load_image):
8849 Don't assume :index value fits in 'int'.
8850 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8851 (imagemagick_load_image): Check that crop parameters fit into
8852 the integer types that MagickCropImage accepts. Don't assume
8853 Vimagemagick_render_type has a nonnegative value. Don't assume
8854 size_t fits in 'long'.
8855 (gs_load): Use printmax_t to print the widest integers possible.

8868 handle_single_display_spec, not just 1 or zero.
8869 (handle_single_display_spec): If the display spec is of the form
8870 `(space ...)', and specifies display in the text area, return 2
8872 (try_cursor_movement): Check for the need to scroll more
8873 accurately, and prefer exact match for point under bidi.
8874 Don't advance `row' beyond the last row of the window.
8876 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8877 into disp_prop; all users changed.
8879 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8895 positioning on the newline at EOL of R2L text within L2R
8896 paragraph, and vice versa.
8897 (try_cursor_movement): Check continued rows, in addition to
8898 continuation rows. Fixes unwarranted scroll when point enters a
8899 continued line of R2L text within an L2R paragraph, or vice versa.
8900 (cursor_row_p): Consider the case of point being equal to
8901 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8902 from the end of a short line to the beginning of a continued line
8903 of R2L text within L2R paragraph.
8904 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

8920 2011-08-22 Kenichi Handa <handa@m17n.org>
8922 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8923 extra slot even if the purpose is char-code-property-table.
8925 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8927 * xdisp.c (redisplay_window): When computing centering_position,
8928 account for the height of the header line. (Bug#8874)
8930 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8931 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8932 candidate is selected by the mouse, and that candidate has a
8933 composed character under the mouse.
8935 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8936 coordinates reported by pos-visible-in-window-p for a composed
8937 character in column zero.

8947 composed buffer positions.
8949 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8951 * image.c (gif_load): Don't assume that each subimage has the same
8952 dimensions as the base image. Handle disposal method that is
8953 "undefined" by the gif spec (Bug#9335).
8955 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8957 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8958 (Fcondition_case): Document `debug' symbol in error handler.
8960 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8962 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8963 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8964 from an Org mode buffer to a Speedbar frame.
8966 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8967 a composition, take its buffer position from IT->cmp_it.charpos.
8968 Fixes cursor positioning at the beginning of a line that begins
8969 with a composed character.
8971 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8973 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8974 character bidirectional type, use STRONG_L instead. Fixes crashes
8975 in a buffer produced by `describe-categories'.
8977 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8978 members before the level stack, so they would be saved and
8979 restored when copying iterator state. Fixes incorrect reordering
8980 around TABs covered by display properties.
8982 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

9068 the event loop. Get status from as_status (Bug#7276).
9070 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9071 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
9072 the event loop (Bug#7276).

9097 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
9098 (Fnetwork_interface_list): Allocate in increments of bytes instead
9099 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
9100 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
9102 (struct ifflag_def): notrailers is smart on OSX.
9103 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9104 Get hardware address with getifaddrs if available.
9106 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9108 * xdisp.c (iterate_out_of_display_property): xassert that
9109 IT->position is set to within IT->object's boundaries. Break from
9110 the loop as soon as EOB is reached; avoids infloops in redisplay
9111 when IT->position is set up wrongly due to some bug.
9112 Set IT->current to match the bidi iterator unconditionally.
9113 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9114 entry. Force push_it to save on the stack the current
9115 buffer/string position, to be restored by pop_it. Fix flags in
9116 the iterator structure wrt the object coming from a display
9117 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9118 properties. (Bug#9284)
9120 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9122 * fontset.c (fontset_get_font_group): Add proper type checks.
9125 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9127 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
9128 and LC_VERSION_MIN_MACOSX.
9129 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
9130 (dump_it) [LC_FUNCTION_STARTS]: Use it.
9132 2011-08-08 Eli Zaretskii <eliz@gnu.org>
9134 * xdisp.c (forward_to_next_line_start): Allow to use the
9135 no-display-properties-and-no-overlays under bidi display.
9136 Set disp_pos in the bidi iterator to avoid searches for display
9137 properties and overlays.
9139 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9141 * editfns.c (Fset_time_zone_rule): Document relationship with the
9144 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9145 the font entity extracted from the cache (Bug#8109).
9147 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9149 * composite.c (autocmp_chars): Don't reset point. That is done by
9150 restore_point_unwind (Bug#5984).
9152 2011-08-07 Juri Linkov <juri@jurta.org>
9154 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9155 to show the arg `TIME' instead of `TIMEVAL'.
9157 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9159 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9160 display property strides EOL and includes a newline, as in
9161 longlines-mode. (Bug#9254)
9162 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9163 word-wrap under bidirectional display. (Bug#9224)
9165 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9166 is non-zero, even if the data buffer is NULL. Fixes a crash in
9167 vertical-motion with longlines-mode. (Bug#9254)
9169 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9171 * bidi.c <bidi_cache_total_alloc>: Now static.
9172 (bidi_initialize): Initialize bidi_cache_total_alloc.
9174 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9177 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9178 amount allocated this far in `bidi_cache_total_alloc'.
9179 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9180 non-zero, only free the data buffer without restoring the cache
9181 contents. All callers changed.
9183 * dispextern.h (bidi_unshelve_cache): Update prototype.
9185 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9186 (move_it_in_display_line, move_it_to)
9187 (move_it_vertically_backward, move_it_by_lines): Replace the call
9188 to xfree to an equivalent call to bidi_unshelve_cache.
9189 (move_it_in_display_line_to): Fix logic of returning
9190 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9192 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9194 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9195 came from a string character with a `cursor' property. (Bug#9229)
9197 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9199 * Makefile.in (LIB_PTHREAD): New variable.
9200 (LIBES): Add LIB_PTHREAD (Bug#9216).
9202 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9203 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9205 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9207 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9209 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9211 * xterm.c (x_find_topmost_parent): New function.
9212 (x_set_frame_alpha): Find topmost parent window with
9213 x_find_topmost_parent and set the property there also (bug#9181).
9214 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9216 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9218 * callproc.c (Fcall_process): Avoid vfork clobbering
9219 the local vars buffer, coding_systems, current_dir.
9221 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9223 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9225 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9227 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9228 so that it is not optimized away.
9230 * xdisp.c (compute_display_string_pos): Remove unused local.
9232 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9234 Fix slow cursor motion and scrolling in large buffers with
9235 selective display, like Org Mode buffers. (Bug#9218)
9237 * dispextern.h (struct bidi_it): New member disp_prop_p.
9239 * xdisp.c: Remove one-slot cache of display string positions.
9240 (compute_display_string_pos): Accept an additional argument
9241 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9242 for a display string or property. If found, set DISP_PROP_P
9245 * bidi.c (bidi_fetch_char): Accept an additional argument
9246 DISP_PROP_P, and pass it to compute_display_string_pos.
9247 Only handle text covered by a display string if DISP_PROP_P is returned
9248 non-zero. All callers of bidi_fetch_char changed.
9250 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9252 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9254 2010-12-03 Don March <don@ohspite.net>
9256 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9257 last character M-[char] is translated to ESC [char] (bug#7541).
9259 2011-08-02 Kenichi Handa <handa@m17n.org>
9261 * lisp.h (uniprop_table): Extern it.
9263 * chartab.c (uniprop_table): Make it non-static.
9265 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9267 * xdisp.c (forward_to_next_line_start): Accept additional argument
9268 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9270 (reseat_at_next_visible_line_start): Use the bidi iterator state
9271 returned by forward_to_next_line_start to restore the state of
9272 it->bidi_it after backing up to previous newline. (Bug#9212)
9274 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9276 * regex.c (re_comp): Protoize.
9277 (re_exec): Fix return type.
9278 (regexec): Fix type of `ret'. (Bug#9203)
9280 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9282 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9283 This is needed if max-image-size is a floating-point number.
9285 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9287 * print.c (print_object): Print empty symbol as ##.
9289 * lread.c (read1): Read ## as empty symbol.
9291 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9293 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9294 setting frame foreground color (Bug#9175).
9295 (x_set_background_color): Likewise.
9297 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9298 contents (Bug#9176).
9299 (EmacsTooltip -init): Remove bezels and add shadows to
9302 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9303 or scroll bar (Bug#8470).
9305 * nsfont.m (nsfont_open): Remove assignment to voffset and
9306 unnecessary vars hshink, expand, hd, full_height, min_height.
9307 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9309 * nsterm.h (nsfont_info): Remove voffset field.
9311 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9313 Implement strike-through and overline on NextStep (Bug#8863).
9315 * nsfont.m (nsfont_open): Use underline position provided by font,
9316 instead of hard-coded value of 2.
9317 (nsfont_draw): Call ns_draw_text_decoration instead.
9319 * nsterm.h: Add declaration for ns_draw_text_decoration.
9321 * nsterm.m (ns_draw_text_decoration): New function for drawing
9322 underline, overline, and strike-through.
9323 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9324 ns_draw_text_decoration. Change treatment of cursor drawing to
9325 accommodate underlining, etc.
9327 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9329 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9332 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9334 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9335 Without this fix, if a signal arrives just after memory fills up,
9336 'malloc' might be invoked reentrantly.
9338 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9339 In other words, assume that every image size is allowed, on non-X
9340 hosts. This assumption is probably wrong, but it lets Emacs compile.
9342 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9344 * regex.c (re_iswctype): Convert return values to boolean.
9346 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9348 * xdisp.c (compute_display_string_pos): Don't use cached display
9349 string position if the buffer had its restriction changed.
9352 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9354 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9356 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9358 Integer signedness and overflow and related fixes. (Bug#9079)
9360 * bidi.c: Integer size and overflow fixes.
9361 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9362 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9363 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9364 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9365 (bidi_find_other_level_edge):
9366 Use ptrdiff_t instead of EMACS_INT where either will do.
9367 This works better on 32-bit hosts configured --with-wide-int.
9368 (bidi_cache_ensure_space): Check for size-calculation overflow.
9369 Use % rather than repeated addition, for better worst-case speed.
9370 Don't set bidi_cache_size until after xrealloc returns, because it
9372 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9373 (bidi_cache_ensure_space): Also check that the bidi cache size
9374 does not exceed that of the largest Lisp string or buffer. See Eli
9375 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9377 * alloc.c (__malloc_size_t): Remove.
9378 All uses replaced by size_t. See Andreas Schwab's note
9379 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9381 * image.c: Improve checking for integer overflow.
9382 (check_image_size): Assume that f is nonnull, since
9383 it is always nonnull in practice. This is one less thing to
9384 worry about when checking for integer overflow later.
9385 (x_check_image_size): New function, which checks for integer
9386 overflow issues inside X.
9387 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9388 This removes the need for a memory_full check.
9389 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9390 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9391 (xbm_read_bitmap_data): Change locals back to 'int', since
9392 their values must fit in 'int'.
9393 (xpm_load_image, png_load, tiff_load):
9394 Invoke x_create_x_image_and_pixmap earlier,
9395 to avoid much needless work if the image is too large.
9396 (tiff_load): Treat overly large images as if
9397 x_create_x_image_and_pixmap failed, not as malloc failures.
9398 (gs_load): Use x_check_image_size.
9400 * gtkutil.c: Omit integer casts.
9401 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9402 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9404 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9406 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9407 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9408 would wrongly return t on a 64-bit host.
9410 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9411 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9412 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9413 and therefore cause GCC to emit a bogus diagnostic in some cases.
9415 * image.c: Integer signedness and overflow and related fixes.
9416 This is not an exhaustive set of fixes, but it's time to
9417 record what I've got.
9418 (lookup_pixel_color, check_image_size): Remove redundant decls.
9419 (check_image_size): Don't assume that arbitrary EMACS_INT values
9420 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9421 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9422 (tiff_load, imagemagick_load_image):
9423 Check for overflow in size calculations.
9424 (x_create_x_image_and_pixmap): Remove unnecessary test for
9425 xmalloc returning NULL; that can't happen.
9426 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9427 (xpm_color_bucket): Use better integer hashing function.
9428 (xpm_cache_color): Don't possibly over-allocate memory.
9429 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9430 (gif_memory_source):
9431 Use ptrdiff_t, not int or size_t, to record sizes.
9432 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9433 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9434 either works, as we prefer signed integers.
9435 (tiff_read_from_memory, tiff_write_from_memory):
9436 Return tsize_t, not size_t, since that's what the TIFF API wants.
9437 (tiff_read_from_memory): Don't fail simply because the read would
9438 go past EOF; instead, return a short read.
9439 (tiff_load): Omit no-longer-needed casts.
9440 (Fimagemagick_types): Don't assume size fits into 'int'.
9442 Improve hashing quality when configured --with-wide-int.
9443 * fns.c (hash_string): New function, taken from sxhash_string.
9444 Do not discard information about ASCII character case; this
9445 discarding is no longer needed.
9446 (sxhash-string): Use it. Change sig to match it. Caller changed.
9447 * lisp.h: Declare it.
9448 * lread.c (hash_string): Remove, since we now use fns.c's version.
9449 The fns.c version returns a wider integer if --with-wide-int is
9450 specified, so this should help the quality of the hashing a bit.
9452 * emacs.c: Integer overflow minor fix.
9453 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9454 Define only if GNU_LINUX.
9455 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9457 * dispnew.c: Integer signedness and overflow fixes.
9458 Remove unnecessary forward decls, that were a maintenance hassle.
9459 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9461 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9462 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9463 (prepare_desired_row, line_draw_cost):
9464 Use int, not unsigned, where either works.
9465 (save_current_matrix, restore_current_matrix):
9466 Use ptrdiff_t, not size_t, where either works.
9467 (init_display): Check for overflow more accurately, and without
9468 relying on undefined behavior.
9470 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9471 Remove, replacing with the new symbols in lisp.h. All uses changed.
9472 * fileio.c (make_temp_name):
9473 * filelock.c (lock_file_1, lock_file):
9474 * xdisp.c (message_dolog):
9475 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9476 Use pMd etc. instead.
9477 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9478 replacing the pWIDE etc. symbols removed from editfns.c.
9480 * keyboard.h (num_input_events): Now uintmax_t.
9481 This is (very slightly) less likely to mess up due to wraparound.
9484 * buffer.c: Integer signedness fixes.
9485 (alloc_buffer_text, enlarge_buffer_text):
9486 Use ptrdiff_t rather than size_t when either will do, as we prefer
9489 * alloc.c: Integer signedness and overflow fixes.
9490 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9491 (__malloc_size_t): Default to size_t, not to int.
9492 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9493 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9494 Prefer ptrdiff_t to size_t when either would do, as we prefer
9496 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9497 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9498 Now const. Initialize with values that are in range even if char
9500 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9501 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9502 These functions do the right thing with sizes > 2**32.
9503 (check_depth): Now ptrdiff_t, not int.
9504 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9505 Adjust to new way of storing sizes. Check for size overflow bugs
9507 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9508 slightly wrong anyway, as it missed one instance of
9509 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9510 (refill_memory_reserve): Omit needless cast to size_t.
9511 (mark_object_loop_halt): Mark as externally visible.
9513 * xselect.c: Integer signedness and overflow fixes.
9514 (Fx_register_dnd_atom, x_handle_dnd_message):
9515 Use ptrdiff_t, not size_t, since we prefer signed.
9516 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9517 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9518 x_dnd_atoms_size and x_dnd_atoms_length.
9520 * doprnt.c: Prefer signed to unsigned when either works.
9522 * doprnt.c (doprnt):
9524 * xdisp.c (vmessage):
9525 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9526 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9527 prefer signed arithmetic to avoid comparison confusion.
9528 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9529 but is a bit tricky.
9531 Assume freestanding C89 headers, string.h, stdlib.h.
9532 * data.c, doprnt.c, floatfns.c, print.c:
9533 Include float.h unconditionally.
9534 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9535 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9536 * regex.c: Likewise for stddef.h, string.h.
9537 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9538 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9539 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9540 (STDC_HEADERS): Remove obsolete defines.
9541 * sysdep.c: Include limits.h unconditionally.
9543 Assume support for memcmp, memcpy, memmove, memset.
9544 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9545 * regex.c (memcmp, memcpy):
9546 Remove; we assume C89 now.
9548 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9549 (__malloc_safe_bcopy): Remove; no longer needed.
9551 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9552 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9553 well either way, and we prefer signed to unsigned.
9555 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9557 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9558 closes the connection while we're reading (bug#9182).
9560 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9562 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9563 are specified (Bug#9168).
9565 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9567 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9568 Found by GCC static checking and --with-wide-int on a 32-bit host.
9570 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9572 * xdisp.c (compute_display_string_pos): Fix logic of caching
9573 previous display string position. Initialize cached_prev_pos to
9574 -1. Fixes slow-down at the beginning of a buffer.
9576 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9578 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9579 for attrs[LFACE_FONTSET_INDEX].
9581 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9583 * xml.c (parse_region): Remove unused local
9584 that was recently introduced.
9586 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9588 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9589 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9591 * xdisp.c (move_it_in_display_line_to): Record the best matching
9592 position for TO_CHARPOS while scanning the line, and restore it on
9593 exit if none of the characters scanned was an exact match.
9594 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9595 when exact match is impossible due to invisible text, and the
9596 lines are truncated.
9598 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9600 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask

9605 Fix a significant slow-down of cursor motion with C-n, C-p,
9606 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9607 auto-repeat under bidi redisplay in fontified buffers.
9608 * xdisp.c (compute_stop_pos_backwards): New function.
9609 (next_element_from_buffer): Call compute_stop_pos_backwards to
9610 find a suitable prev_stop when we find ourselves before
9612 (reseat): Don't look for prev_stop, as that could mean a very long
9614 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9615 <cached_disp_overlay_modiff>: Cache for last found display string
9617 (compute_display_string_pos): Return the cached position if asked
9618 about the same buffer in the same area of character positions, and
9619 the buffer wasn't changed since the time the display string
9620 position was cached.
9622 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9624 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9625 is an integer, which is important for empty lines. (Bug#9149)
9627 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9629 * frame.c (Fmodify_frame_parameters): In tty case, update the
9630 default face if necessary (Bug#4238).
9632 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9634 * editfns.c (Fstring_to_char): No need to explain what a character
9635 is in the docstring (Bug#6576).
9637 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9639 * xml.c (parse_region): Make sure we always return a tree.
9641 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9643 * xml.c (parse_region): If a document contains only comments,
9646 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9648 * xml.c (make_dom): Return comments, too.
9650 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9653 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9654 and the surrounding thread.
9655 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9656 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9657 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9659 * s/openbsd.h (BROKEN_SIGIO): Define.
9660 * unexelf.c (unexec) [__OpenBSD__]:
9661 Don't update the .mdebug section of the Alpha COFF symbol table.
9663 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9665 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9668 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>

9671 This fixes some race conditions on the permissions of any newly
9674 * alloc.c (valid_pointer_p): Use pipe, not open.
9675 This fixes some permissions issues when debugging.
9677 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9678 If fchown fails to set both uid and gid, try to set just gid,
9679 as that is sometimes allowed. Adjust the file's mode to eliminate
9680 setuid or setgid bits that are inappropriate if fchown fails.
9682 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9684 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9685 to compare Lisp_Objects.

9696 symbol character follows.
9698 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9700 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9701 This works around a problem with the previous change to Fcopy_file.
9702 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9703 and without this change, GCC might complain about discarding
9704 fchown's return value.
9706 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9708 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9710 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9712 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9714 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9716 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9717 it's used from the C level.
9719 * process.c: Use the same condition for POLL_FOR_INPUT in both
9720 keyboard.c and process.c (bug#1858).
9722 2011-07-09 Lawrence Mitchell <wence@gmx.li>

9729 * doc.c (Fsubstitute_command_keys): Revert last change.
9731 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9733 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9734 quotes the next character, and doesn't affect other longer
9735 sequences (bug#8935).
9737 * lread.c (syms_of_lread): Clarify that is isn't only
9738 `eval-buffer' and `eval-defun' that's affected by
9739 `lexical-binding' (bug#8460).

9743 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9744 bidi redisplay when a line includes both an image and is truncated.

9749 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9750 (elsz): Now a signed constant, not a size_t var. We prefer signed
9751 types to unsigned, to avoid integer comparison confusion. Without
9752 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9753 "cannot optimize loop, the loop counter may overflow", a symptom
9755 * indent.c (Fvertical_motion): Mark locals as initialized.
9756 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9758 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9760 * search.c (Fre_search_backward): Mention `case-fold-search' in
9761 all the re_search_* functions (bug#8138).

9781 buffer position was specified. Initialize paragraph_embedding to
9783 (reseat_to_string): Initialize the bidi iterator.
9784 (display_string): If we need to ignore text properties of
9785 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

9790 (compute_display_string_end): Support display properties on Lisp
9792 (init_iterator, reseat_1, reseat_to_string): Initialize the
9793 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9794 when iterating on a string not from display properties).

9796 Fix calculation of the object to scan. Fixes an error when using
9798 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9799 base_level_stop; instead, set base_level_stop to BEGV.
9800 Fixes crashes in vertical-motion.
9801 (next_element_from_buffer): Improve commentary for when
9802 the iterator is before prev_stop.
9803 (init_iterator): Initialize bidi_p from the default value of
9804 bidi-display-reordering, not from buffer-local value. Use the
9805 buffer-local value only if initializing for buffer iteration.

9807 that are being bidi-reordered.
9808 (set_iterator_to_next): Support bidi reordering of C strings and

9826 parts of next_element_from_buffer, next_element_from_string, and
9827 next_element_from_c_string.
9828 (tool_bar_lines_needed, redisplay_tool_bar)
9829 (display_menu_bar): Force left-to-right direction. Add a FIXME

9844 pushed the iterator stack, restore the internal state of the bidi
9845 iterator by calling bidi_pop_it same number of times.
9846 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9847 and we are bidi-iterating, don't decrement the iterator position;
9848 instead, set the first_elt flag in the bidi iterator, to produce
9850 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9851 (push_display_prop): xassert that we are iterating a buffer.

9858 (compute_display_string_end): Fix handling the case of C string.
9859 (push_it, pop_it): Save and restore from_disp_prop_p.
9860 (handle_single_display_spec, push_display_prop): Set the
9861 from_disp_prop_p flag.
9862 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

10016 In theory, the old code could also have corrupted Emacs internals,

10322 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10323 subseconds part to the entropy, as that's a bit more random.
10324 Prefer signed to unsigned, since the signedness doesn't matter and
10325 in general we prefer signed. When given a limit, use a
10326 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10327 latter isn't right if USE_2_TAGS_FOR_INTS.
10328 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10329 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10342 This is more efficient than Ffile_directory_p and avoids a minor race.

10346 * buffer.c (Foverlay_put): Say what the return value is

10372 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
10373 Also (re)move comments that are misplaced or no longer relevant.

10469 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
10472 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
10474 * eval.c (struct backtrace): Simplify and port the data structure.
10475 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10476 signed bit field, as this assumption is not portable and it makes
10477 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10478 "char debug_on_exit : 1" as this is not portable either; instead,
10479 use the portable "unsigned int debug_on_exit : 1". Remove unused
10480 member evalargs. Remove obsolete comments about cc bombing out.
10482 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

10550 (emacs_fixed_new): Set priv->f to argument.
10551 (emacs_fixed_get_preferred_width)
10552 (emacs_fixed_get_preferred_height): Use min_width/height from
10553 frames size_hint to set minimum and natural (Bug#8919).
10554 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
10555 and use min_width/height from frames size_hint to set
10556 min_width/height (Bug#8919).

10576 Use gnulib's dup2 module instead of rolling our own.
10577 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

10644 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10646 Integer and buffer overflow fixes (Bug#8873).
10648 * print.c (printchar, strout): Check for string overflow.
10649 (PRINTPREPARE, printchar, strout):
10650 Don't set size unless allocation succeeds.
10652 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10653 for sizes. Check for string overflow more accurately.
10654 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10656 * macros.c: Integer and buffer overflow fixes.
10657 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10658 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

10662 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10664 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10666 * lread.c: Integer overflow fixes.
10667 (read_integer): Radix is now EMACS_INT, not int,
10668 to improve quality of diagnostics for out-of-range radices.
10669 Calculate buffer size correctly for out-of-range radices.
10670 (read1): Check for integer overflow in radices, and in
10671 read-circle numbers.
10672 (read_escape): Avoid int overflow.
10673 (Fload, openp, read_buffer_size, read1)
10674 (substitute_object_recurse, read_vector, read_list, map_obarray):
10675 Use ptrdiff_t, not int, for sizes.

10690 2011-06-22 Leo Liu <sdl.web@gmail.com>
10692 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10693 Move to minibuffer.el.
10695 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10697 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10698 The following patches are for when GLYPH_DEBUG && !XASSERT.
10699 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10700 * dispnew.c (flush_stdout):
10701 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10702 Mark as externally visible.
10703 * dispnew.c (check_window_matrix_pointers): Now static.
10704 * dispnew.c (window_to_frame_vpos):
10705 * xfns.c (unwind_create_frame):
10706 * xterm.c (x_check_font): Remove unused local.
10707 * scroll.c (CHECK_BOUNDS):
10708 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10709 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10710 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10711 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10712 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10714 (debug_method_add): Use va_list and vsprintf rather than relying
10715 on undefined behavior with wrong number of arguments.
10716 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10717 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10718 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10719 since we're not interested in debugging glyphs with old libraries.
10720 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10721 GCC 4.6.0's static checking.
10723 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10725 Integer overflow and signedness fixes (Bug#8873).

10735 (x_create_bitmap_from_xpm_data):
10736 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10737 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10739 * xfaces.c (load_pixmap):
10740 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10741 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10742 (.bitmaps_last, struct x_output.icon_bitmap):
10743 Use ptrdiff_t, not int, for bitmap indexes.
10744 (x_allocate_bitmap_record): Check for size overflow.
10745 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10747 Use ptrdiff_t, not int, for overlay counts.
10748 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10749 * editfns.c (overlays_around, get_pos_property):
10750 * textprop.c (get_char_property_and_overlay):
10751 * xdisp.c (next_overlay_change, note_mouse_highlight):
10752 * xfaces.c (face_at_buffer_position):
10753 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10754 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10755 (Fnext_overlay_change, Fprevious_overlay_change)
10756 (mouse_face_overlay_overlaps, Foverlays_in):
10757 Use ptrdiff_t, not int, for sizes.
10758 (overlays_at, overlays_in): Check for size-calculation overflow.
10760 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10762 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10763 (x_session_initialize): Do not assume string length fits in int.
10765 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10766 This is unlikely, but can occur if DPI is outlandish.
10768 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10769 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10771 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10772 * xrdb.c (magic_file_p, search_magic_path):
10773 Omit last arg SUFFIX; it was always 0. All callers changed.
10774 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10776 * xfont.c (xfont_match): Avoid need for strlen.
10778 * xfns.c: Don't assume strlen fits in int.
10779 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10781 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10782 not unsigned long, as we prefer signed integers. All callers changed.
10783 Detect integer overflow in repeat count.
10784 (message_dolog): Don't assume print length fits in 39 bytes.
10785 (display_mode_element): Don't assume strlen fits in int.
10787 * termcap.c: Don't assume sizes fit in int and never overflow.
10788 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10789 (gobble_line): Check for size-calculation overflow.
10791 * minibuf.c (Fread_buffer):
10792 * lread.c (intern, intern_c_string):
10793 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10794 Don't assume string length fits in int.

10797 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10799 * font.c: Don't assume string length fits in int.

10803 Don't assume integer property fits in fixnum.
10804 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10806 * filelock.c: Fix some buffer overrun and integer overflow issues.
10807 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10808 Reformulate so as not to need the command string.
10809 Invoke gzip -cd rather than gunzip, as it's more portable.
10810 (lock_info_type, lock_file_1, lock_file):
10811 Don't assume pid_t and time_t fit in unsigned long.
10812 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10813 (current_lock_owner): Prefer signed type for sizes.
10814 Use memcpy, not strncpy, where memcpy is what is really wanted.
10815 Don't assume (via atoi) that time_t and pid_t fit in int.
10816 Check for time_t and/or pid_t out of range, e.g., via a network share.
10817 Don't alloca where an auto var works fine.
10819 * fileio.c: Fix some integer overflow issues.
10820 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10821 Don't assume string length fits in int.
10822 (directory_file_name): Don't assume string length fits in long.
10823 (make_temp_name): Don't assume pid fits in int, or that its print
10824 length is less than 20.
10826 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10828 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10830 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10832 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10833 We prefer signed integers, even for size calculations.
10835 * emacs.c: Don't assume string length fits in 'int'.
10836 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10837 (main): Don't invoke strlen when not needed.

10842 * callproc.c (getenv_internal_1, getenv_internal)
10843 (Fgetenv_internal):
10844 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10846 * lread.c (invalid_syntax): Omit length argument.
10847 All uses changed. This doesn't fix a bug, but it simplifies the
10848 code away from its former Hollerith-constant appearance, and it's
10849 one less 'int' to worry about when looking at integer-overflow issues.
10850 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10852 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10853 This didn't break anything, but it didn't help either.
10854 It's confusing to put a bogus integer in a place where the actual
10855 value does not matter.
10856 (LIST_END_P): Remove unused macro and its bogus comment.
10857 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10859 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10860 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10862 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10863 We prefer signed types, and the value cannot exceed the EMACS_INT
10864 range anyway (because otherwise the length would not be representable).
10865 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10866 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10867 This avoids a GCC warning when WIDE_EMACS_INT.
10869 * indent.c (sane_tab_width): New function.
10870 (current_column, scan_for_column, Findent_to, position_indentation)
10871 (compute_motion): Use it. This is just for clarity.
10872 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10874 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10876 * lisp.h (lint_assume): New macro.
10877 * composite.c (composition_gstring_put_cache):
10878 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10880 * editfns.c, insdel.c:
10881 Omit unnecessary forward decls, to simplify future changes.
10883 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10885 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10887 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10888 Use much-faster test for byte-length change.
10889 Don't assume string byte-length fits in 'int'.
10890 Check that character arg fits in 'int'.
10891 (mapcar1): Declare byte as byte, for clarity.
10893 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10895 * fns.c (concat): Catch string overflow earlier.
10896 Do not rely on integer wraparound.
10898 * dispextern.h (struct it.overlay_strings_charpos)
10899 (struct it.selective): Now EMACS_INT, not int.
10900 * xdisp.c (forward_to_next_line_start)
10901 (back_to_previous_visible_line_start)
10902 (reseat_at_next_visible_line_start, next_element_from_buffer):
10903 Don't arbitrarily truncate the value of 'selective' to int.
10905 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10907 * composite.c: Don't truncate sizes to 'int'.
10908 (composition_gstring_p, composition_reseat_it)
10909 (composition_adjust_point): Use EMACS_INT, not int.
10910 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10911 not EMACS_UINT, for indexes.
10913 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10915 * buffer.c: Include <verify.h>.
10916 (struct sortvec.priority, struct sortstr.priority):
10917 Now EMACS_INT, not int.
10918 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10919 (struct sortstr.size, record_overlay_string)
10920 (struct sortstrlist.size, struct sortlist.used):
10921 Don't truncate size to int.
10922 (record_overlay_string): Check for size-calculation overflow.
10923 (init_buffer_once): Check at compile-time, not run-time.
10925 2011-06-22 Jim Meyering <meyering@redhat.com>
10927 Don't leak an XBM-image-sized buffer
10928 * image.c (xbm_load): Free the image buffer after using it.
10930 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10933 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10934 that Sun C diagnosed.
10935 * fns.c (secure_hash): Fix pointer signedness issue.
10936 * intervals.c (static_offset_intervals): New function.
10937 (offset_intervals): Use it.
10939 2011-06-21 Leo Liu <sdl.web@gmail.com>
10942 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10945 * fns.c (secure_hash): Rename from crypto_hash_function and change
10946 the first arg to accept symbols.
10947 (Fsecure_hash): New primitive.
10948 (syms_of_fns): New symbols.
10950 2011-06-20 Deniz Dogan <deniz@dogan.se>
10952 * process.c (Fset_process_buffer): Clarify return value in
10955 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10957 * dispnew.c (add_window_display_history): Use BVAR.
10959 * xdisp.c (debug_method_add): Use BVAR.
10960 (check_window_end, dump_glyph_matrix, dump_glyph)
10961 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10963 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10966 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10967 check till after the cache is created in init_frame_faces.
10969 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10971 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10973 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10975 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10976 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10977 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10979 Improve buffer-overflow checking (Bug#8873).
10980 * fileio.c (Finsert_file_contents):
10981 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10982 Remove the old (too-loose) buffer overflow checks.
10983 They weren't needed, since make_gap checks for buffer overflow.
10984 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10985 The old code merely checked for Emacs fixnum overflow, and relied
10986 on undefined (wraparound) behavior. The new code avoids undefined
10987 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10989 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10990 Tune. Don't use wider integers than needed. Don't use alloca.
10991 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10993 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10995 * insdel.c, lisp.h (buffer_overflow): New function.
10996 (insert_from_buffer_1, replace_range, replace_range_2):
10997 * insdel.c (make_gap_larger):
10998 * editfns.c (Finsert_char):
10999 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
11001 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
11003 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
11005 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
11007 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
11008 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
11010 * fileio.c: Don't assume EMACS_INT fits in off_t.
11011 (emacs_lseek): New static function.
11012 (Finsert_file_contents, Fwrite_region): Use it.
11013 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
11015 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
11017 * fns.c: Don't overflow int when computing a list length.
11018 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
11019 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
11020 truncation on 64-bit hosts. Check for QUIT every
11021 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
11022 faster and is responsive enough.
11023 (Flength): Report an error instead of overflowing an integer.
11024 (Fsafe_length): Return a float if the value is not representable
11025 as a fixnum. This shouldn't happen except in contrived situations.
11026 (Fnthcdr, Fsort): Don't assume list length fits in int.
11027 (Fcopy_sequence): Don't assume vector length fits in int.
11029 * alloc.c: Check that resized vectors' lengths fit in fixnums.
11030 (header_size, word_size): New constants.
11031 (allocate_vectorlike): Don't check size overflow here.
11032 (allocate_vector): Check it here instead, since this is the only
11033 caller of allocate_vectorlike that could cause overflow.
11034 Check that the new vector's length is representable as a fixnum.
11036 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11037 The previous code was bogus. For example, next_almost_prime (32)
11038 returned 39, which is undesirable as it is a multiple of 3; and
11039 next_almost_prime (24) returned 25, which is a multiple of 5 so
11040 why was the code bothering to check for multiples of 7?
11042 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11044 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11046 Variadic C functions now count arguments with ptrdiff_t.
11047 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11048 Back then I didn't know that the Emacs coding style prefers signed int.
11049 Also, in the meantime I found a few more instances where arguments
11050 were being counted with int, which may truncate counts on 64-bit
11051 machines, or EMACS_INT, which may be unnecessarily wide.
11052 * lisp.h (struct Lisp_Subr.function.aMANY)
11053 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11054 Arg counts are now ptrdiff_t, not size_t.
11055 All variadic functions and their callers changed accordingly.
11056 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11057 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11058 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11059 * callint.c (Fcall_interactively): Check arg count for overflow,
11060 to avoid potential buffer overrun. Use signed char, not 'int',
11061 for 'varies' array, so that we needn't bother to check its size
11062 calculation for overflow.
11063 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11064 * eval.c (apply_lambda):
11065 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11066 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11067 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11069 * callint.c (Fcall_interactively): Don't use index var as event count.
11071 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11072 * mem-limits.h (SIZE): Remove; no longer used.
11074 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11076 Remove unnecessary casts.
11077 * xterm.c (x_term_init):
11078 * xfns.c (x_set_border_pixel):
11079 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11080 These aren't needed now that we assume ANSI C.
11082 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11083 It's more likely to cause problems (due to unsigned overflow)
11086 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11088 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11090 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11092 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11094 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11096 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11098 GLYPH_CODE_FACE returns EMACS_INT, not int.
11099 * dispextern.h (merge_faces):
11100 * xfaces.c (merge_faces):
11101 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11102 Don't assume EMACS_INT fits in int.
11104 * character.h (CHAR_VALID_P): Remove unused parameter.
11105 * fontset.c, lisp.h, xdisp.c: All uses changed.
11107 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11109 * fns.c (concat): Minor tuning based on overflow analysis.
11110 This doesn't fix any bugs. Use int to hold character, instead
11111 of constantly refetching from Emacs object. Use XFASTINT, not
11112 XINT, for value known to be a character. Don't bother comparing
11113 a single byte to 0400, as it's always less.
11115 * floatfns.c (Fexpt):
11116 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11118 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11121 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11123 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11124 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11125 incorrectly succeed when S was a string, because 4294967386 was
11126 truncated before it was used.
11128 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11129 Otherwise, an out-of-range integer could cause undefined behavior
11132 * composite.c: Use int, not EMACS_INT, for characters.
11133 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11134 EMACS_INT, for values that are known to be in character range.
11135 This doesn't fix any bugs but is the usual style inside Emacs and
11136 may generate better code on 32-bit machines.
11138 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11139 This is for reasons similar to the recent CHAR_STRING fix.
11140 * charset.c (Fencode_char): Check that character arg is actually
11141 a character. Pass an int to ENCODE_CHAR.
11142 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11143 wider than 'int', as a compile-time check to prevent future regressions
11146 * character.c (char_string): Remove unnecessary casts.
11148 Make sure a 64-bit char is never passed to CHAR_STRING.
11149 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11150 by silently ignoring the top 32 bits, allowing some values
11151 that were far too large to be valid characters.
11152 * character.h: Include <verify.h>.
11153 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11154 arguments are no wider than unsigned, as a compile-time check
11155 to prevent future regressions in this area.
11157 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11158 (Fsubst_char_in_region):
11160 * xdisp.c (decode_mode_spec_coding):
11161 Adjust to CHAR_STRING's new requirement.
11162 * editfns.c (Finsert_char, Fsubst_char_in_region):
11163 * fns.c (concat): Check that character args are actually
11164 characters. Without this test, these functions did the wrong
11165 thing with wildly out-of-range values on 64-bit hosts.
11167 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11168 These casts should not be needed on 32-bit hosts, either.
11169 * keyboard.c (read_char):
11170 * lread.c (Fload): Remove casts to unsigned.
11172 * lisp.h (UNSIGNED_CMP): New macro.
11173 This fixes comparison bugs on 64-bit hosts.
11174 (ASCII_CHAR_P): Use it.
11175 * casefiddle.c (casify_object):
11176 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11177 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11178 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11179 * dispextern.h (FACE_FROM_ID):
11180 * keyboard.c (read_char): Use UNSIGNED_CMP.
11182 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11183 not to EMACS_INT, to avoid GCC warning.
11185 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11187 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11188 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11189 isn't needed on 32-bit machines.
11191 * buffer.c (Fgenerate_new_buffer_name):
11192 Use EMACS_INT for count, not int.
11193 (advance_to_char_boundary): Return EMACS_INT, not int.
11195 * data.c (Qcompiled_function): Now static.
11197 * window.c (window_body_lines): Now static.
11199 * image.c (gif_load): Rename local to avoid shadowing.
11201 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11202 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11203 * alloc.c (make_save_value): Integer argument is now of type
11204 ptrdiff_t, not int.
11205 (mark_object): Use ptrdiff_t, not int.
11206 * lisp.h (pD): New macro.
11207 * print.c (print_object): Use it.
11209 * alloc.c: Use EMACS_INT, not int, to count objects.
11210 (total_conses, total_markers, total_symbols, total_vector_size)
11211 (total_free_conses, total_free_markers, total_free_symbols)
11212 (total_free_floats, total_floats, total_free_intervals)
11213 (total_intervals, total_strings, total_free_strings):
11214 Now EMACS_INT, not int. All uses changed.
11215 (Fgarbage_collect): Compute overall total using a double, so that
11216 integer overflow is less likely to be a problem. Check for overflow
11217 when converting back to an integer.
11218 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11219 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11220 These were 'int' variables that could overflow on 64-bit hosts;
11221 they were never used, so remove them instead of repairing them.
11222 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11223 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
11224 Previously, this ceilinged at INT_MAX, but that doesn't work on
11226 (allocate_pseudovector): Don't use EMACS_INT when int would do.
11228 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
11229 (allocate_vectorlike): Check for ptrdiff_t overflow.
11230 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
11231 when a (possibly-narrower) signed value would do just as well.
11232 We prefer using signed arithmetic, to avoid comparison confusion.
11234 * alloc.c: Catch some string size overflows that we were missing.
11235 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
11236 for convenience in STRING_BYTES_MAX.
11237 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11238 The definition here is exact; the one in lisp.h was approximate.
11239 (allocate_string_data): Check for string overflow. This catches
11240 some instances we weren't catching before. Also, it catches
11241 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11242 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11243 and ptrdiff_t and EMACS_INT are both 64 bits.
11245 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11246 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
11247 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
11249 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
11251 * alloc.c (Fmake_string): Check for out-of-range init.
11253 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
11255 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
11257 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
11259 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
11260 xg_get_default_scrollbar_width.
11262 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
11263 (int_gtk_range_get_value): Move to the scroll bar part of the file.
11264 (style_changed_cb): Call update_theme_scrollbar_width and call
11265 x_set_scroll_bar_default_width and xg_frame_set_char_size for
11266 all frames (Bug#8505).
11267 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
11268 Call gtk_window_set_resizable if HAVE_GTK3.
11269 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
11270 and height if HAVE_GTK3 (Bug#8505).
11271 (scroll_bar_width_for_theme): New variable.
11272 (update_theme_scrollbar_width): New function.
11273 (xg_get_default_scrollbar_width): Move code to
11274 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
11275 (xg_initialize): Call update_theme_scrollbar_width.
11277 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
11279 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
11281 2011-06-12 Martin Rudalics <rudalics@gmx.at>
11283 * frame.c (make_frame): Call other_buffer_safely instead of
11286 * window.c (temp_output_buffer_show): Call display_buffer with
11287 second argument Vtemp_buffer_show_specifiers and reset latter
11288 immediately after the call.
11289 (Vtemp_buffer_show_specifiers): New variable.
11290 (auto_window_vscroll_p, next_screen_context_lines)
11291 (Vscroll_preserve_screen_position): Remove leading asterisks from
11294 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
11296 Fix minor problems found by GCC 4.6.0 static checking.
11297 * buffer.c (Qclone_number): Remove for now, as it's unused.
11298 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
11299 (record_buffer): Remove unused local.
11300 * frame.c (other_visible_frames, frame_buffer_list): Now static.
11301 (set_frame_buffer_list): Remove; unused.
11302 * frame.h (other_visible_frames): Remove decl.
11303 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
11304 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
11305 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
11307 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
11308 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
11309 Define only if HAVE_GPM.
11310 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
11311 (update_hints_inhibit): Remove; never set. All uses removed.
11312 * widgetprv.h (emacsFrameClassRec): Remove decl.
11313 * window.c (delete_deletable_window): Now returns void, since it
11314 wasn't returning anything.
11315 (compare_window_configurations): Remove unused locals.
11316 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
11317 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
11318 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
11319 the same widths as pointers. This follows up on the 2011-05-06 patch.
11320 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
11321 * xterm.h: Likewise.
11322 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
11324 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
11326 * makefile.w32-in: Update dependencies.
11327 (LISP_H): Add lib/intprops.h.
11329 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
11331 * image.c (gif_load): Add animation frame delay to the metadata.

11787 Obey Vx_select_enable_clipboard_manager. Catch errors in
11788 x_clipboard_manager_save (Bug#8779).
11789 (Vx_select_enable_clipboard_manager): New variable.
11790 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
11792 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
11794 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
11796 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11798 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
11799 in the current matrix if keep_current_p is non-zero.

11803 * bidi.c (bidi_level_of_next_char): Fix last change.
11805 2011-06-03 Eli Zaretskii <eliz@gnu.org>
11807 Support bidi reordering of text covered by display properties.
11809 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
11810 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
11811 (bidi_cache_search, bidi_cache_iterator_state)
11812 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11813 (bidi_level_of_next_char, bidi_move_to_visually_next):
11814 Support character positions inside a run of characters covered by a
11816 (bidi_paragraph_init, bidi_resolve_explicit_1)
11817 (bidi_level_of_next_char): Call bidi_fetch_char and
11818 bidi_fetch_char_advance instead of FETCH_CHAR and
11819 FETCH_CHAR_ADVANCE.
11820 (bidi_init_it): Initialize new members.
11821 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11823 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11824 instead of using explicit *_CHAR codes.
11825 (bidi_resolve_explicit, bidi_resolve_weak):
11826 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11827 bidirectional text is supported only in multibyte buffers.
11828 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11829 it to initialize the frame_window_p member of struct bidi_it.
11830 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11831 (bidi_resolve_explicit, bidi_resolve_weak)
11832 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
11833 bidi_it->nchars is non-positive.
11834 (bidi_level_of_next_char): Don't try to lookup the cache for the
11835 next/previous character if nothing is cached there yet, or if we
11836 were just reseat()'ed to a new position.
11838 * xdisp.c (set_cursor_from_row): Set start and stop points
11839 according to the row's direction when priming the loop that looks
11840 for the glyph on which to display cursor.
11841 (single_display_spec_intangible_p): Function deleted.
11842 (display_prop_intangible_p): Reimplement to call
11843 handle_display_spec instead of single_display_spec_intangible_p.
11844 Accept 3 additional arguments needed by handle_display_spec.
11845 This fixes incorrect cursor motion across display property with complex
11846 values: lists, `(when COND...)' forms, etc.
11847 (single_display_spec_string_p): Support property values that are
11848 lists with the argument STRING its top-level element.
11849 (display_prop_string_p): Fix the condition for processing a
11850 property that is a list to be consistent with handle_display_spec.
11851 (handle_display_spec): New function, refactored from the
11852 last portion of handle_display_prop.
11853 (compute_display_string_pos): Accept additional argument
11854 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11855 value of a `display' property is a "replacing spec".
11856 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11857 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11858 the display property, but just return a value indicating whether
11859 the display property will replace the characters it covers.
11860 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11861 frame_window_p members of struct bidi_it.
11862 (compute_display_string_pos, compute_display_string_end):
11864 (push_it): Accept second argument POSITION, where pop_it should
11865 jump to continue iteration.
11866 (reseat_1): Initialize bidi_it.disp_pos.
11868 * keyboard.c (adjust_point_for_property): Adjust the call to
11869 display_prop_intangible_p to its new signature.
11871 * dispextern.h (struct bidi_it): New member frame_window_p.
11872 (bidi_init_it): Update prototypes.
11873 (display_prop_intangible_p): Update prototype.
11874 (compute_display_string_pos, compute_display_string_end):
11875 Declare prototypes.
11876 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11879 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11881 Malloc failure behavior now depends on size of allocation.
11882 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11883 * lisp.h: Change signatures accordingly.
11884 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11885 All callers changed. (Bug#8762)
11887 * gnutls.c: Use Emacs's memory allocators.
11888 Without this change, the gnutls library would invoke malloc etc.
11889 directly, which causes problems on non-SYNC_INPUT hosts, and which
11890 runs afoul of improving memory_full behavior. (Bug#8761)
11891 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11892 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11893 xfree instead of the default malloc, realloc, free.
11894 (Fgnutls_boot): No need to check for memory allocation failure,
11895 since xmalloc does that for us.
11897 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11898 * category.c (hash_get_category_set):
11899 * ccl.c (ccl_driver):
11900 * charset.c (Fdefine_charset_internal):
11901 * charset.h (struct charset.hash_index):
11902 * composite.c (get_composition_id, gstring_lookup_cache)
11903 (composition_gstring_put_cache):
11904 * composite.h (struct composition.hash_index):
11905 * dispextern.h (struct image.hash):
11906 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11907 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
11908 (hashfn_equal, hashfn_user_defined, make_hash_table)
11909 (maybe_resize_hash_table, hash_lookup, hash_put)
11910 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11911 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11912 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11913 * image.c (make_image, search_image_cache, lookup_image)
11914 (xpm_put_color_table_h):
11915 * lisp.h (struct Lisp_Hash_Table):
11916 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11917 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11918 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11919 * alloc.c (allocate_vectorlike):
11920 Check for overflow in vector size calculations.
11921 * ccl.c (ccl_driver):
11922 Check for overflow when converting EMACS_INT to int.
11923 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11924 need to be updated by these changes.
11925 * fns.c (make_hash_table, maybe_resize_hash_table):
11926 Check for integer overflow with large hash tables.
11927 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11928 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11929 (SXHASH_REDUCE): New macro.
11930 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11931 Use it instead of discarding useful hash info with large hash values.
11932 (sxhash_float): New function.
11933 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11934 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11935 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11936 Rewrite to use FIXNUM_BITS, as this simplifies things.
11937 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11938 Adjust signatures to match updated version of code.
11939 (consing_since_gc): Now EMACS_INT, since a single hash table can
11940 use more than INT_MAX bytes.
11942 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11944 Make it possible to build with GCC-4.6+ -O2 -flto.
11946 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11948 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11950 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11951 Call minibuffer-inactive-mode.
11953 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11955 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11956 Update dependencies.
11958 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11960 * data.c (init_data): Remove code for UTS, this system is not
11963 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11965 Don't force ./temacs to start in terminal mode.
11967 * frame.c (make_initial_frame): Initialize faces in all cases, not
11968 only when CANNOT_DUMP is defined.
11969 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11971 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11973 * dispnew.c (add_window_display_history): Use const for the string
11974 pointer. Remove declaration, not needed.
11976 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11978 Use 'inline', not 'INLINE'.
11979 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11980 * alloc.c, fontset.c (INLINE): Remove.
11981 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11982 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11983 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11984 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11985 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11987 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11989 Make it possible to run ./temacs.
11991 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11992 syms_of_callproc does the same thing. Remove test for
11993 "initialized", do it in the caller.
11994 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11996 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11998 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11999 (read_minibuf): Use get_minibuffer.
12000 (syms_of_minibuf): Use DEFSYM.
12001 (Qmetadata): New var.
12002 * data.c (Qbuffer): Don't make it static.
12003 (syms_of_data): Use DEFSYM.
12005 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12007 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
12008 (CCL_CODE_MIN): New macro.
12010 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
12012 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
12014 * eval.c (Qdebug): Now static.
12015 * lisp.h (Qdebug): Remove decl. This reverts a part of the
12016 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
12017 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
12019 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12021 * image.c: Various fixes to ImageMagick code comments.
12022 (Fimagemagick_types): Doc fix.
12024 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
12026 Minor fixes prompted by GCC 4.6.0 warnings.
12028 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12030 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12031 (x_clipboard_manager_save_all): Move extern decl to ...
12032 * xterm.h: ... here, so that it can be checked for consistency.
12034 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12036 * xselect.c (x_clipboard_manager_save_frame)
12037 (x_clipboard_manager_save_all): New functions.
12038 (Fx_clipboard_manager_save): Lisp function deleted.
12040 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12041 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12043 * xterm.h: Update prototype.
12045 2011-05-28 William Xu <william.xwl@gmail.com>
12047 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12048 exiting (Bug#8239).
12050 2011-05-28 Jim Meyering <meyering@redhat.com>
12052 Avoid a sign-extension bug in crypto_hash_function.
12053 * fns.c (to_uchar): Define.
12054 (crypto_hash_function): Use it to convert some newly-signed
12055 variables to unsigned, to avoid sign-extension bugs. For example,
12056 without this change, (md5 "truc") would evaluate to
12057 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12058 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12059 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12061 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12063 Integer overflow fixes.
12065 * dbusbind.c: Serial number integer overflow fixes.
12066 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12067 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12068 to hold a serial number that is too large for a fixnum.
12069 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12070 Check for serial numbers out of range. Decode any serial number
12071 that was so large that it became a float. (Bug#8722)
12073 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12074 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12075 Use XFASTINT rather than XUINT when numbers are nonnegative.
12076 (xd_append_arg, Fdbus_method_return_internal):
12077 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12078 arguments, check that Lisp number is nonnegative, rather than
12079 silently wrapping negative numbers around. (Bug#8722)
12080 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12083 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12085 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12087 ccl: Add integer overflow checks.
12088 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12089 (IN_INT_RANGE): New macros.
12090 (ccl_driver): Use them to check for integer overflow when
12091 decoding a CCL program. Many of the new checks are whether XINT (x)
12092 fits in int; it doesn't always, on 64-bit hosts. The new version
12093 doesn't catch all possible integer overflows, but it's an
12094 improvement. (Bug#8719)
12096 * alloc.c (make_event_array): Use XINT, not XUINT.
12097 There's no need for unsigned here.
12099 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12100 This follows up to the 2011-05-06 change that substituted uintptr_t
12101 for EMACS_INT. This case wasn't caught back then.
12103 Rework Fformat to avoid integer overflow issues.
12104 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12105 now (part of C89). Include <verify.h>.
12106 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12107 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12108 (Fformat): Avoid the prepass trying to compute sizes; it was only
12109 approximate and thus did not catch overflow reliably. Instead, walk
12110 through the format just once, formatting and computing sizes as we go,
12111 checking for integer overflow at every step, and allocating a larger
12112 buffer as needed. Keep track separately whether the format is
12113 multibyte. Keep only the most-recently calculated precision, rather
12114 than them all. Record whether each argument has been converted to
12115 string. Use EMACS_INT, not int, for byte and char and arg counts.
12116 Support field widths and precisions larger than INT_MAX. Avoid
12117 sprintf's undefined behavior with conversion specifications such as %#d
12118 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12119 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12120 formatting out-of-range floating point numbers with int
12121 formats. (Bug#8668)
12123 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12125 * data.c: Avoid integer truncation in expressions involving floats.
12126 * data.c: Include <intprops.h>.
12127 (arith_driver): When there's an integer overflow in an expression
12128 involving floating point, convert the integers to floating point
12129 so that the resulting value does not suffer from catastrophic
12130 integer truncation. For example, on a 64-bit host (* 4
12131 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12132 Do not rely on undefined behavior after integer overflow.
12134 merge count_size_as_multibyte, parse_str_to_multibyte
12135 * character.c, character.h (count_size_as_multibyte):
12136 Rename from parse_str_to_multibyte; all uses changed.
12137 Check for integer overflow.
12138 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12139 since it's now a duplicate of the other. This is more of
12140 a character than a buffer op, so better that it's in character.c.
12141 * fns.c, print.c: Adjust to above changes.
12143 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12145 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12147 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12149 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12150 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12151 (x_clipboard_manager_save): Now static.
12152 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12154 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12155 (crypto_hash_function): Now static.
12156 Fix pointer signedness problems. Avoid unnecessary initializations.
12158 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12160 * termhooks.h (Vselection_alist): Make it terminal-local.
12162 * terminal.c (create_terminal): Initialize it.
12164 * xselect.c: Support for clipboard managers.
12165 (Vselection_alist): Move to termhooks.h as terminal-local var.
12166 (LOCAL_SELECTION): New macro.
12167 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12168 (symbol_to_x_atom): Remove gratuitous arg.
12169 (x_handle_selection_request, lisp_data_to_selection_data)
12170 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12171 (x_own_selection, x_get_local_selection, x_convert_selection):
12172 New arg, specifying work frame. Use terminal-local Vselection_alist.
12173 (some_frame_on_display): Delete unused function.
12174 (Fx_own_selection_internal, Fx_get_selection_internal)
12175 (Fx_disown_selection_internal, Fx_selection_owner_p)
12176 (Fx_selection_exists_p): New optional frame arg.
12177 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12178 (x_handle_selection_clear): Don't treat other terminals with the
12179 same keyboard specially. Use the terminal-local Vselection_alist.
12180 (x_clear_frame_selections): Use Frun_hook_with_args.
12182 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12184 * xterm.h: Add support for those atoms.
12186 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12188 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12189 (converted_selections, conversion_fail_tag): New global variables.
12190 (x_selection_request_lisp_error): Free the above.
12191 (x_get_local_selection): Remove unnecessary code.
12192 (x_reply_selection_request): Args changed; handle arbitrary array
12193 of converted selections stored in converted_selections.
12194 Separate the XChangeProperty and SelectionNotify steps.
12195 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12196 (x_convert_selection): New function.
12197 (x_handle_selection_event): Simplify.
12198 (x_get_foreign_selection): Don't ignore incoming requests while
12199 waiting for an answer; this will fail when we implement
12200 SAVE_TARGETS, and seems unnecessary anyway.
12201 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12202 (Vx_sent_selection_functions): Doc fix.
12204 2011-05-26 Leo Liu <sdl.web@gmail.com>
12206 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12208 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12210 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12212 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12213 for fringe update if it has periodic bitmap.
12214 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12215 and fringe_bitmap_periodic_p.
12217 * fringe.c (get_fringe_bitmap_data): New function.
12218 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12219 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12220 row. Mark glyph row for fringe update if periodicity changed.
12222 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12223 for fringe update unless it has periodic bitmap.
12225 2011-05-25 Kenichi Handa <handa@m17n.org>
12227 * xdisp.c (get_next_display_element): Set correct it->face_id for
12228 a static composition.
12230 2011-05-24 Leo Liu <sdl.web@gmail.com>
12233 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12235 * fns.c (crypto_hash_function, Fsha1): New function.
12236 (Fmd5): Use crypto_hash_function.
12237 (syms_of_fns): Add Ssha1.
12239 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12241 * gnutls.c: Remove unused macros.
12242 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12243 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12244 Remove macros that are defined and never used.
12245 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12247 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12249 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12250 (Fx_get_selection_internal): Minor cleanup.
12251 (Fx_own_selection_internal): Rename arguments for consistency with
12254 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12256 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12258 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12260 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12262 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12264 * dispnew.c (scrolling_window): Don't exclude the case that the
12265 last enabled row in the desired matrix touches the bottom boundary.
12267 2011-05-21 Glenn Morris <rgm@gnu.org>
12269 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12270 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12271 and add some more files.
12273 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12275 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12276 report_file_error introduced by the change from 2011-05-07.
12278 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12280 * systime.h (Time): Define only if emacs is defined.
12281 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12282 where the include path doesn't have X11/X.h by default. See
12283 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12285 2011-05-20 Kenichi Handa <handa@m17n.org>
12287 * composite.c (find_automatic_composition): Fix previous change.
12289 2011-05-20 Glenn Morris <rgm@gnu.org>
12291 * lisp.mk: New file, split from Makefile.in.
12292 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12293 (shortlisp): Remove.
12294 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12296 2011-05-19 Glenn Morris <rgm@gnu.org>
12298 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12299 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12300 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12301 (lisp): Set the order to that of loadup.el.
12302 (shortlisp): Make it a copy of $lisp.
12303 (SOME_MACHINE_LISP): Remove.
12304 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12305 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12307 2011-05-18 Kenichi Handa <handa@m17n.org>
12309 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12310 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12311 (find_automatic_composition): Mostly rewrite for efficiency.
12313 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12315 * makefile.w32-in: Update dependencies.
12317 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12319 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12320 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12322 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12324 Fix some integer overflow issues, such as string length overflow.
12326 * insdel.c (count_size_as_multibyte): Check for string overflow.
12328 * character.c (lisp_string_width): Check for string overflow.
12329 Use EMACS_INT, not int, for string indexes and lengths; in
12330 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12331 the resulting string length overflows an EMACS_INT; instead,
12332 report a string overflow if no precision given. When checking for
12333 precision exhaustion, use a check that cannot possibly have
12334 integer overflow. (Bug#8675)
12335 * character.h (lisp_string_width): Adjust to new signature.
12337 * alloc.c (string_overflow): New function.
12338 (Fmake_string): Use it. This doesn't change behavior, but saves
12339 a few bytes and will simplify future changes.
12340 * character.c (string_escape_byte8): Likewise.
12341 * lisp.h (string_overflow): New decl.
12343 Fixups, following up to the user-interface timestamp change.
12344 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12345 for UI timestamps, instead of unsigned long.
12346 * msdos.c (mouse_get_pos): Likewise.
12347 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12348 * w32gui.h (Time): Define by including "systime.h" rather than by
12349 declaring it ourselves. (Bug#8664)
12351 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12352 * image.c (clear_image_cache): Likewise.
12354 * term.c (term_mouse_position): Don't assume time_t wraparound.
12356 Be more systematic about user-interface timestamps.
12357 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12358 and sometimes 'EMACS_UINT', to represent these timestamps.
12359 This change causes it to use 'Time' uniformly, as that's what X uses.
12360 This makes the code easier to follow, and makes it easier to catch
12361 integer overflow bugs such as Bug#8664.
12362 * frame.c (Fmouse_position, Fmouse_pixel_position):
12363 Use Time, not unsigned long, for user-interface timestamps.
12364 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12365 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12366 * keyboard.h (last_event_timestamp): Likewise.
12367 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12368 * menu.h (xmenu_show): Likewise.
12369 * term.c (term_mouse_position): Likewise.
12370 * termhooks.h (struct input_event.timestamp): Likewise.
12371 (struct terminal.mouse_position_hook): Likewise.
12372 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12373 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12374 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12375 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12376 what it was before.
12377 * menu.h, termhooks.h: Include "systime.h", for Time.
12379 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12380 Don't assume that the difference between two unsigned long values
12381 can fit into an integer. At this point, we know button_down_time
12382 <= event->timestamp, so the difference must be nonnegative, so
12383 there's no need to cast the result if double-click-time is
12384 nonnegative, as it should be; check that it's nonnegative, just in
12385 case. This bug is triggered when events are more than 2**31 ms
12386 apart (about 25 days). (Bug#8664)
12388 * xselect.c (last_event_timestamp): Remove duplicate decl.
12389 (x_own_selection): Remove needless cast to unsigned long.
12391 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12392 that always fit in int. Use a sentinel instead of a counter, to
12393 avoid a temp and to allay GCC's concerns about possible int overflow.
12394 * frame.h (struct frame): Use int for menu_bar_items_used
12395 instead of EMACS_INT, since it always fits in int.
12397 * menu.c (grow_menu_items): Check for int overflow.
12399 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12401 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12402 Before, the code was not consistent. These values cannot exceed
12403 2**31 - 1 so there's no need to make them unsigned.
12404 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12405 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12406 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12408 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12410 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12411 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12412 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12413 presumably because the widths might not match.
12415 * window.c (size_window): Avoid needless test at loop start.
12417 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12419 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12421 2011-05-12 Drew Adams <drew.adams@oracle.com>
12423 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12425 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12427 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12428 `width' to `bar_area_x' and `bar_area_width', respectively.
12429 (x_scroll_run): Take account of fringe background extension.
12431 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12432 Rename local vars `left' and `width' to `bar_area_x' and
12433 `bar_area_width', respectively.
12434 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12435 background extension.
12437 2011-05-10 Jim Meyering <meyering@redhat.com>
12439 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12441 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12443 * image.c (Finit_image_library): Return t for built-in image types,
12444 like pbm and xbm. (Bug#8640)
12446 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12448 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12450 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12452 * w32console.c (Fset_screen_color): Doc fix.
12453 (Fget_screen_color): New function.
12454 (syms_of_ntterm): Defsubr it.
12456 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12457 unlink the temporary file if Fcall_process didn't create it in the
12459 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12460 child process will be redirected to a file specified with `:file'.
12461 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12462 cue to call_process_cleanup not to close that handle.
12464 2011-05-07 Ben Key <bkey76@gmail.com>
12466 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12467 one of two shell specific rules, either bootstrap-temacs-CMD or
12468 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12469 to the previous implementation of the bootstrap-temacs rule.
12470 The bootstrap-temacs-CMD rule is similar to the previous
12471 implementation of the bootstrap-temacs rule except that it
12472 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12475 These changes, along with some changes to nt/configure.bat,
12476 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12477 earlier fix to add support for --cflags and --ldflags options
12478 that include quotes so that it works whether make uses cmd or
12481 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12483 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12484 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12486 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12487 a string. Handle both cases.
12488 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12489 (Fdbus_register_method): Use Qinvalid_function.
12491 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12493 * makefile.w32-in: Update dependencies.
12494 (LISP_H): Add inttypes.h and stdin.h.
12495 (PROCESS_H): Add unistd.h.
12497 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12499 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12500 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12502 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12504 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12506 * term.c (vfatal): Remove stray call to va_end.
12507 It's not needed and the C Standard doesn't allow it here anyway.
12509 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12510 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12512 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12515 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12517 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12519 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12521 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12523 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12525 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12526 * charset.c (Fdefine_charset_internal): Don't initialize
12527 charset.code_space[15]. The value was garbage, on hosts with
12528 32-bit int (Bug#8600).
12530 * lread.c (read_integer): Be more consistent with string-to-number.
12531 Use string_to_number to do the actual conversion; this avoids
12532 rounding errors and fixes some other screwups. Without this fix,
12533 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12534 (digit_to_number): Move earlier, for benefit of read_integer.
12535 Return -1 if the digit is out of range for the base, -2 if it is
12536 not a digit in any supported base. (Bug#8602)
12538 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12540 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12541 to match comment at start of function. This also removes a
12542 GCC warning about overflow in a 32+64-bit port.
12544 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12546 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12547 Reported by Stefan Monnier in
12548 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12549 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12550 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12552 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12553 (EMACS_UINTPTR): Likewise, with uintptr_t.
12555 * lisp.h: Prefer 64-bit EMACS_INT if available.
12556 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12557 on 32-bit hosts that have 64-bit int, so that they can access
12559 However, temporarily disable this change unless the temporary
12560 symbol WIDE_EMACS_INT is defined.
12562 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12564 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12565 This removes an assumption that EMACS_INT and long are the same
12566 width as pointers. The assumption is true for Emacs porting targets
12567 now, but we want to make other targets possible.
12568 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12569 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12570 In the rest of the code, change types of integers that hold casted
12571 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12572 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12573 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12574 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12575 No need to cast type when ORing.
12576 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12577 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12578 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12579 assume EMACS_INT is the same width as char *.
12580 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12581 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12582 Remove no-longer-needed casts.
12583 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12584 (xg_tool_bar_help_callback, xg_make_tool_item):
12585 Use EMACS_INTPTR to hold an integer
12586 that will be cast to void *; this can avoid a GCC warning
12587 if EMACS_INT is not the same width as void *.
12588 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12589 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12590 (current_message_1, set_message_1):
12591 Use a local to convert to proper width without a cast.
12592 * xmenu.c (dialog_selection_callback): Likewise.
12594 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12595 Also, don't assume VALBITS / RAND_BITS is less than 5,
12596 and don't rely on undefined behavior when shifting a 1 left into
12598 * lisp.h (get_random): Change signature to match.
12600 * lread.c (hash_string): Use size_t, not int, for hash computation.
12601 Normally we prefer signed values; but hashing is special, because
12602 it's better to use unsigned division on hash table sizes so that
12603 the remainder is nonnegative. Also, size_t is the natural width
12604 for hashing into memory. The previous code used 'int', which doesn't
12605 retain enough info to hash well into very large tables.
12606 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12608 * dbusbind.c: Don't possibly lose pointer info when converting.
12609 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12610 Use XPNTR rather than XHASH, so that the high-order bits of
12611 the pointer aren't lost when converting through void *.
12613 * eval.c (Fautoload): Don't double-shift a pointer.
12615 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12617 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12619 * gnutls.c (DEF_GNUTLS_FN):
12620 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12622 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12624 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12627 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12629 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12630 New version that can reserve upto 2GB of heap space.
12632 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12634 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12636 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12638 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to

12698 * process.c: Include lisp.h before w32.h, not after.
12699 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12700 instead of gnutls_record_check_pending.
12702 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12704 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12706 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

12752 rather than `XVECTOR (FOO)->size'.
12754 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12755 inttypes.h, as a gnulib replacement is used if it not available in
12758 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12760 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

12770 charbuf for the composition carryover bytes.
12772 2011-04-21 Eli Zaretskii <eliz@gnu.org>

12775 aborting when %lld or %lll format is passed.
12776 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12777 %llo or %llx format is passed. (Bug#8545)
12779 * window.c (window_scroll_line_based): Use a marker instead of
12780 simple variables to record original value of point. (Bug#7952)
12782 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12783 produced by %s or %c overflows available buffer space. (Bug#8545)
12785 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12787 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12788 (SIZE_MAX): Move defn after all includes, as they might #define it.
12790 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12792 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12794 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12796 * keyboard.c (Qdelayed_warnings_hook): Define.
12797 (command_loop_1): Run `delayed-warnings-hook'
12798 if Vdelayed_warnings_list is non-nil.
12799 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12800 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12802 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12804 * doprnt.c (doprnt): Don't return value smaller than the buffer
12805 size if the message was truncated. (Bug#8545).
12807 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12809 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12810 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12812 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12814 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12816 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12818 * makefile.w32-in: Update dependencies.
12820 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12822 Improve `doprnt' and its usage. (Bug#8545)
12823 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12824 `format_end'. Remove support for %l as a conversion specifier.
12825 Don't use xrealloc. Improve diagnostics when the %l size modifier
12826 is used. Update the commentary.
12828 * eval.c (verror): Simplify calculation of size_t.
12830 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12833 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12835 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12838 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12840 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12841 This makes this file independent of the recent pseudovector change.
12843 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12845 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12847 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12848 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12849 Remove unused local.
12850 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12852 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12853 GCC 4.6.0 optimizes based on type-based alias analysis.
12854 For example, if b is of type struct buffer * and v of type struct
12855 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12856 != &v->size, and therefore "v->size = 1; b->size = 2; return
12857 v->size;" must therefore return 1. This assumption is incorrect
12858 for Emacs, since it type-puns struct Lisp_Vector * with many other
12859 types. To fix this problem, this patch adds a new type struct
12860 vectorlike_header that documents the constraints on layout of vectors
12861 and pseudovectors, and helps optimizing compilers not get fooled
12862 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12863 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12864 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12866 (XSETPVECTYPE): Rewrite in terms of new macro.
12867 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12868 This is a bit clearer, and further avoids the possibility of
12869 undesirable aliasing.
12870 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12871 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12872 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12873 since Lisp_Subr is a special case (no "next" field).
12874 (ASIZE): Now uses header.size rather than size.
12875 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12876 to avoid the hassle of writing XVECTOR (foo)->header.size.
12877 (struct vectorlike_header): New type.
12878 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12879 object, to help avoid aliasing.
12880 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12881 (SUBRP): Likewise, since Lisp_Subr is a special case.
12882 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12883 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12884 (struct Lisp_Hash_Table): Combine first two members into a single
12885 struct vectorlike_header member. All uses of "size" and "next" members
12886 changed to be "header.size" and "header.next".
12887 * buffer.h (struct buffer): Likewise.
12888 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12889 * frame.h (struct frame): Likewise.
12890 * process.h (struct Lisp_Process): Likewise.
12891 * termhooks.h (struct terminal): Likewise.
12892 * window.c (struct save_window_data, struct saved_window): Likewise.
12893 * window.h (struct window): Likewise.
12894 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12895 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12896 * buffer.c (init_buffer_once): Likewise.
12897 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12899 * process.c (Fformat_network_address): Use local var for size,
12902 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12904 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12905 * data.c (atof): Remove decl; no longer used or needed.
12906 (digit_to_number): Move to lread.c.
12907 (Fstring_to_number): Use new string_to_number function, to be
12908 consistent with how the Lisp reader treats infinities and NaNs.
12909 Do not assume that floating-point numbers represent EMACS_INT
12910 without losing information; this is not true on most 64-bit hosts.
12911 Avoid double-rounding errors, by insisting on integers when
12912 parsing non-base-10 numbers, as the documentation specifies.
12913 * lisp.h (string_to_number): New decl, replacing ...
12914 (isfloat_string): Remove.
12915 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12916 (read1): Do not accept +. and -. as integers; this
12917 appears to have been a coding error. Similarly, do not accept
12918 strings like +-1e0 as floating point numbers. Do not report
12919 overflow for integer overflows unless the base is not 10 which
12920 means we have no simple and reliable way to continue.
12921 Break out the floating-point parsing into a new
12922 function string_to_number, so that Fstring_to_number parses
12923 floating point numbers consistently with the Lisp reader.
12924 (digit_to_number): Move here from data.c. Make it static inline.
12925 (E_CHAR, EXP_INT): Remove, replacing with ...
12926 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12927 (string_to_number): New function, replacing isfloat_string.
12928 This function checks for valid syntax and produces the resulting
12929 Lisp float number too. Rework it so that string-to-number
12930 no longer mishandles examples like "1.0e+". Use strtoumax,
12931 so that overflow for non-base-10 numbers is reported only when
12932 there's no portable and simple way to convert to floating point.
12934 * textprop.c (set_text_properties_1): Rewrite for clarity,
12935 and to avoid GCC warning about integer overflow.
12937 * intervals.h (struct interval): Use EMACS_INT for members
12938 where EMACS_UINT might cause problems. See
12939 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12940 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12941 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12943 (offset_intervals): Tell GCC not to worry about length overflow
12944 when negating a negative length.
12946 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12947 (overrun_check_free): Likewise.
12949 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12950 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12953 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12954 (gnutls_make_error): Rename local to avoid shadowing.
12955 (gnutls_emacs_global_deinit): ifdef out; not used.
12956 (Fgnutls_boot): Use const for pointer to readonly storage.
12957 Comment out unused local. Fix pointer signedness problems.
12959 * lread.c (openp): Don't stuff size_t into an 'int'.
12960 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12961 about possible signed overflow.
12963 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12964 (GDK_KEY_g): Don't define if already defined.
12965 (xg_prepare_tooltip): Avoid pointer signedness problem.
12966 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12968 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12969 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12971 * xfns.c (Fx_window_property): Simplify a bit,
12972 to make a bit faster and to avoid GCC 4.6.0 warning.
12973 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12975 * fns.c (internal_equal): Don't assume size_t fits in int.
12977 * alloc.c (compact_small_strings): Tighten assertion a little.
12979 Replace pEd with more-general pI, and fix some printf arg casts.
12980 * lisp.h (pI): New macro, generalizing old pEd macro to other
12981 conversion specifiers. For example, use "...%"pI"d..." rather
12982 than "...%"pEd"...".
12983 (pEd): Remove. All uses replaced with similar uses of pI.
12984 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12985 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12986 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12987 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12988 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12989 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12990 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12992 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12993 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12994 * print.c (safe_debug_print, print_object): Likewise.
12995 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12997 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12998 avoiding the 0 flag, which is not portable.
12999 * process.c (Fmake_network_process): Use pI to avoid cast.
13000 * region-cache.c (pp_cache): Likewise.
13001 * xdisp.c (decode_mode_spec): Likewise.
13002 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
13003 behavior on 64-bit hosts with printf arg.
13004 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
13005 (x_stop_queuing_selection_requests): Likewise.
13006 (x_get_window_property): Don't truncate byte count to an 'int'
13009 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
13010 here, since it parses constructs like leading '-' and spaces,
13011 which are not wanted; and it overflows with large numbers.
13012 Instead, simply match F[0-9]+, which is what is wanted anyway.
13014 * alloc.c: Remove unportable assumptions about struct layout.
13015 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
13016 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
13017 (allocate_vectorlike, make_pure_vector): Use the new macros,
13018 plus offsetof, to remove unportable assumptions about struct layout.
13019 These assumptions hold on all porting targets that I know of, but
13020 they are not guaranteed, they're easy to remove, and removing them
13021 makes further changes easier.
13023 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
13024 This doesn't fix a bug but makes the code clearer.
13025 (string_overrun_cookie): Now const. Use initializers that
13026 don't formally overflow signed char, to avoid warnings.
13027 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
13028 can cause Emacs to crash when string overrun checking is enabled.
13029 (allocate_buffer): Don't assume sizeof (struct buffer) is a
13030 multiple of sizeof (EMACS_INT); it need not be, if
13031 alignof(EMACS_INT) < sizeof (EMACS_INT).
13032 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
13034 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
13036 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
13038 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
13040 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
13041 supposed to be handshaking. (Bug#8556)
13042 Reported by Paul Eggert <eggert@cs.ucla.edu>.
13044 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
13046 * lisp.h (Qdebug): List symbol.
13047 * eval.c (Qdebug): Restore global linkage.
13048 * keyboard.c (debug-on-event): New variable.
13049 (handle_user_signal): Break into debugger when debug-on-event
13050 matches the current signal symbol.
13052 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>

13805 to see whether these functions can be called from other modules.
13806 DEFUN now defines a static function. To make the function external
13807 so that it can be used in other C modules, use the new macro DEFUE.

13885 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13886 since callers should never pass a negative size.
13887 Change the signature to match that of plain 'read' and 'write'; see
13888 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13889 * lisp.h: Update prototypes of emacs_write and emacs_read.
13891 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13893 * xdisp.c (redisplay_window): Don't try to determine the character
13894 position of the scroll margin if the window start point w->startp
13895 is outside the buffer's accessible region. (Bug#8468)
13897 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13899 Fix write-region and its subroutines for buffers > 2GB.
13900 * fileio.c (a_write, e_write): Modify declaration of arguments and
13901 local variables to support buffers larger than 2GB.
13902 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13904 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13905 argument, local variables, and return value.
13907 * lisp.h: Update prototypes of emacs_write and emacs_read.
13909 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13911 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13913 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

13917 * xdisp.c (vmessage): Use a better test for character truncation.
13919 * charset.c (load_charset_map): <, not <=, for optimization,

13929 * callint.c (Fcall_interactively): <, not <=, for optimization.
13930 (Fcall_interactively): Count the number of arguments produced,
13931 not the number of arguments given. This is simpler and lets GCC
13932 4.6.0 generate slightly better code.
13934 * ftfont.c: Distingish more carefully between FcChar8 and char.
13935 The previous code passed unsigned char * to a functions like
13936 strlen and xstrcasecmp that expect char *, which does not
13937 conform to the C standard.
13938 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13939 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13940 char * when the C standard requires it.
13942 * keyboard.c (read_char): Remove unused var.
13944 * eval.c: Port to Windows vsnprintf (Bug#8435).

13947 (verror): Do not give up if vsnprintf returns a negative count.
13948 Instead, grow the buffer. This ports to Windows vsnprintf, which
13949 does not conform to C99. Problem reported by Eli Zaretskii.
13950 Also, simplify the allocation scheme, by avoiding the need for
13951 calling realloc, and removing the ALLOCATED variable.
13953 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13955 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13956 But keep the doprint source code for now, as we might revamp it
13957 and use it again (Bug#8435).
13958 * lisp.h (doprnt): Remove.
13959 * Makefile.in (base_obj): Remove doprnt.o.
13960 * deps.mk (doprnt.o): Remove.
13962 error: Print 32- and 64-bit integers portably (Bug#8435).
13963 Without this change, on typical 64-bit hosts error ("...%d...", N)
13964 was used to print both 32- and 64-bit integers N, which relied on
13965 undefined behavior.
13966 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13967 * lisp.h (error, verror): Mark as printf-like functions.
13968 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13969 Report overflow in size calculations when allocating printf buffer.
13970 Do not truncate output string at its first null byte.
13971 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13972 Truncate the output at a character boundary, since vsnprintf does not
13974 * charset.c (check_iso_charset_parameter): Convert internal
13975 character to string before calling 'error', since %c now has the
13977 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13978 overflow when computing char to be passed to 'error'. Do not
13979 pass Lisp_Object to 'error'; pass the integer instead.
13980 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13981 formatted with plain %d.
13983 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13985 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13987 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13989 * xterm.c (x_catch_errors): Remove duplicate declaration.
13991 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13993 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13995 2011-04-10 Jim Meyering <meyering@redhat.com>
13997 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13998 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13999 return ssize_t not "int", and use size_t as the buffer length.
14000 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
14001 * gnutls.h: Update declarations.
14002 * process.c (read_process_output): Use ssize_t, to match.
14003 (send_process): Likewise.
14005 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14007 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
14009 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14011 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
14012 Use unsigned char, to match FcChar8 type definition.
14014 * xterm.c (handle_one_xevent):
14015 * xmenu.c (create_and_show_popup_menu):
14016 * xselect.c (x_decline_selection_request)
14017 (x_reply_selection_request): Avoid type-punned deref of X events.
14019 2011-04-09 Eli Zaretskii <eliz@gnu.org>
14021 Fix some uses of `int' instead of EMACS_INT.
14022 * search.c (string_match_1, fast_string_match)

14028 * xdisp.c (display_count_lines): 3rd argument and return value now
14029 EMACS_INT. All callers changed.
14030 (pint2hrstr): Last argument is now EMACS_INT.
14032 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)

14045 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
14046 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
14048 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
14049 (encode_invocation_designation): Last argument P_NCHARS is now
14051 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
14052 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
14054 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
14057 * ccl.c (Fccl_execute_on_string): Declare some variables
14060 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

14075 instead of using internal_with_output_to_temp_buffer.
14076 (Qhelp_form_show): New var.
14077 (syms_of_keyboard): Use DEFSYM macro.
14079 * print.c (internal_with_output_to_temp_buffer): Function deleted.

14102 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
14104 * xdisp.c (vmessage): Mark as a printf-like function.
14106 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

14113 to system-supplied API.
14115 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14117 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14118 This avoids several warnings with gcc -Wstrict-overflow.
14119 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14120 directly, rather than having caller test rule sign. This avoids
14121 some unnecessary tests.
14122 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14123 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14124 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14126 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14127 (xfont_open): Avoid unnecessary tests.
14129 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14131 * composite.h, composite.c (composition_gstring_put_cache):
14132 Use EMACS_INT, not int, for length.

14135 breaking out part of COMPOSITION_DECODE_RULE.
14136 (COMPOSITION_DECODE_RULE): Use it.
14137 * composite.c (get_composition_id): Remove unused local vars,
14138 by using the new macro.
14140 * textprop.c (set_text_properties_1): Change while to do-while,
14141 since the condition is always true at first.
14143 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14144 (interval_deletion_adjustment): Return unsigned value.
14147 * process.c (list_processes_1, create_pty, read_process_output):
14148 (exec_sentinel): Remove vars that were set but not used.
14149 (create_pty): Remove unnecessary "volatile"s.

14159 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
14160 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
14161 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
14163 * print.c (print_error_message): Avoid int overflow.
14165 * font.c (font_list_entities): Redo for clarity,
14166 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14168 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14169 (font_score): Avoid potential overflow in diff calculation.
14171 * fns.c (substring_both): Remove var that is set but not used.
14172 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14174 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14176 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14177 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14178 can always succeed if overflow has undefined behavior.
14180 * search.c (boyer_moore, wordify): Remove vars set but not used.
14181 (wordify): Omit three unnecessary tests.
14183 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
14184 All callers changed. This avoids the need for an unused var.
14186 * casefiddle.c (casify_region): Remove var that is set but not used.
14188 * dired.c (file_name_completion): Remove var that is set but not used.
14190 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
14192 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
14193 (Finsert_file_contents): Remove unnecessary code checking fd.
14195 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14196 Check for integer overflow on size calculations.
14198 * buffer.c (Fprevious_overlay_change): Remove var that is set
14201 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14202 Remove vars that are set but not used.
14203 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
14204 (timer_check_2): Mark vars as initialized.
14206 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
14208 * image.c (lookup_image): Remove var that is set but not used.
14209 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
14211 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14212 that are set but not used.
14214 * xfns.c (make_invisible_cursor): Don't return garbage
14215 if XCreateBitmapFromData fails (Bug#8410).
14217 * xselect.c (x_get_local_selection, x_handle_property_notify):
14218 Remove vars that are set but not used.
14220 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
14221 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
14223 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
14224 Remove var that is set but not used.
14225 (scroll_bar_windows_size): Now size_t, not int.
14226 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
14227 Check for overflow.
14229 * xfaces.c (realize_named_face): Remove vars that are set but not used.
14230 (map_tty_color) [!defined MSDOS]: Likewise.
14232 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14234 * coding.c: Remove vars that are set but not used.
14235 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14236 All callers changed.
14237 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
14238 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
14239 (decode_coding_charset): Remove vars that are set but not used.
14241 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
14242 that is set but not used.
14244 * print.c (print_object): Remove var that is set but not used.
14246 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14247 The gnulib version avoids calling malloc in the usual case,
14248 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14249 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14250 * filelock.c (current_lock_owner): Likewise.
14251 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14252 * sysdep.c: Include allocator.h, careadlinkat.h.
14253 (emacs_no_realloc_allocator): New static constant.
14254 (emacs_readlink): New function.
14255 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14256 ../lib/careadlinkat.h.
14258 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14260 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14261 first non-nil return value).
14263 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
14265 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
14266 if not defined (Bug#8403).

14275 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
14276 and thereabouts. All callers changed.
14277 (get_per_char_metric): Remove parameter `f', unused since
14278 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
14280 2011-04-02 Jim Meyering <meyering@redhat.com>
14282 do not dereference NULL upon failed strdup
14283 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
14284 (ns_get_family): Likewise.
14286 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14288 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
14290 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
14292 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
14295 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
14297 Add lexical binding.
14299 * window.c (Ftemp_output_buffer_show): New fun.

14310 (syms_of_lread): Declare `lexical-binding'.
14312 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
14314 * keyboard.c (eval_dyn): New fun.
14315 (menu_item_eval_property): Use it.
14317 * image.c (parse_image_spec): Use Ffunctionp.
14319 * fns.c (concat, mapcar1): Accept byte-code-functions.
14321 * eval.c (Fsetq): Handle lexical vars.
14322 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
14323 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
14324 (FletX, Flet): Obey lexical binding.
14325 (Fcommandp): Handle closures.
14326 (Feval): New `lexical' arg.
14327 (eval_sub): New function extracted from Feval. Use it almost
14328 everywhere where Feval was used. Look up vars in lexical env.
14330 (Ffunctionp): Move from subr.el.
14331 (Ffuncall): Handle closures.
14332 (apply_lambda): Remove `eval_flags'.
14333 (funcall_lambda): Handle closures and new byte-code-functions.
14334 (Fspecial_variable_p): New function.
14335 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14336 but without exporting it to Lisp.
14338 * doc.c (Fdocumentation, store_function_docstring):
14339 * data.c (Finteractive_form): Handle closures.
14341 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14344 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14346 (exec_byte_code): New function extracted from Fbyte_code to handle new
14347 calling convention for byte-code-functions. Add new byte-codes.
14349 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14351 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14353 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14355 * xdisp.c (redisplay_internal): Fix prototype.
14357 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14359 * xdisp.c (SCROLL_LIMIT): New macro.
14360 (try_scrolling): Use it when setting scroll_limit.
14361 Limit scrolling to 100 screen lines.
14362 (redisplay_window): Even when falling back on "recentering",
14363 position point in the window according to scroll-conservatively,
14364 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14366 (try_scrolling): When point is above the window, allow searching
14367 as far as scroll_max, or one screenful, to compute vertical
14368 distance from PT to the scroll margin position. This prevents
14369 try_scrolling from unnecessarily failing when
14370 scroll-conservatively is set to a value slightly larger than the
14371 window height. Clean up the case of PT below the margin at bottom
14372 of window: scroll_max can no longer be INT_MAX. When aggressive
14373 scrolling is in use, don't let point enter the opposite scroll
14374 margin as result of the scroll.
14375 (syms_of_xdisp) <scroll-conservatively>: Document the
14376 threshold of 100 lines for never-recentering scrolling.

14383 (message_log_check_duplicate): Remove parameters `prev_bol' and
14384 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14385 (redisplay_internal): Remove parameter `preserve_echo_area',
14386 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14388 * indent.c (Fvertical_motion):
14389 * window.c (window_scroll_pixel_based, Frecenter):
14390 Don't pass `need_y_p' to `move_it_by_lines'.
14392 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14394 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14395 steal a few bits to be more compact.
14396 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14397 Remove unneeded casts.
14399 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14401 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14403 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14404 binding" message (bug#7967).
14406 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14408 Fix more problems found by GCC 4.6.0's static checks.
14410 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14411 Remove unused local var.
14413 * editfns.c (Fmessage_box): Remove unused local var.
14415 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14416 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14417 Omit unused local vars.
14418 * window.c (shrink_windows): Omit unused local var.
14419 * menu.c (digest_single_submenu): Omit unused local var.
14420 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14421 Omit unused local var.
14423 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14424 Don't assume string length fits in int.
14425 (keyremap_step, read_key_sequence): Use size_t for sizes.
14426 (read_key_sequence): Don't check last_real_key_start redundantly.
14428 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14429 instead of alloca (Bug#8344).
14431 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14432 (Fbacktrace_frame): Don't assume nframes fits in int.
14434 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14436 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14439 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14441 * cm.c (calccost): Turn while-do into do-while, for clarity.
14443 * keyboard.c (syms_of_keyboard): Use the same style as later
14444 in this function when indexing through an array. This also
14445 works around GCC bug 48267.
14447 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14449 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

14452 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14454 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14455 This avoids undefined behavior on integer overflow, and is a bit
14456 more convenient anyway since it is compared to a size_t variable.
14458 Variadic C functions now count arguments with size_t, not int.
14459 This avoids an unnecessary limitation on 64-bit machines, which
14460 caused (substring ...) to crash on large vectors (Bug#8344).
14461 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14462 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14463 All variadic functions and their callers changed accordingly.
14464 (struct gcpro.nvars): Now size_t, not int. All uses changed.

14466 * editfns.c (general_insert_function): Likewise.
14467 * eval.c (struct backtrace.nargs, interactive_p)
14468 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14469 (funcall_lambda, mark_backtrace): Likewise.
14470 * fns.c (concat): Likewise.
14471 * frame.c (x_set_frame_parameters): Likewise.
14472 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14473 0 if not found, not -1. All callers changed.
14475 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14476 (stack_copy_size): Now size_t, not int.
14477 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14479 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14481 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14482 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14483 All callers changed.
14485 * lisp.h (multibyte_char_to_unibyte):
14486 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14487 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14488 * character.h (CHAR_TO_BYTE8):
14489 * cmds.c (internal_self_insert):
14490 * editfns.c (general_insert_function):
14491 * keymap.c (push_key_description):
14492 * search.c (Freplace_match):
14493 * xdisp.c (message_dolog, set_message_1): All callers changed.
14495 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14497 * keyboard.c (safe_run_hook_funcall): New function.
14498 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14499 don't set the hook to nil, but remove the offending function instead.
14500 (Qcommand_hook_internal): Remove, unused.
14501 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14502 Vcommand_hook_internal.
14504 * eval.c (enum run_hooks_condition): Remove.
14505 (funcall_nil, funcall_not): New functions.
14506 (run_hook_with_args): Call each function through a `funcall' argument.
14507 Remove `cond' argument, now redundant.
14508 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14509 (Frun_hook_with_args_until_failure): Adjust accordingly.
14510 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14512 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14514 * dispextern.h (string_buffer_position): Remove declaration.
14516 * print.c (strout): Remove parameter `multibyte', unused since
14517 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14519 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14520 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14521 All callers changed.
14523 * w32.c (_wsa_errlist): Use braces for struct initializers.
14525 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14526 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14527 All callers changed.
14528 (string_buffer_position): Likewise. Also, make static (it's never
14529 used outside xdisp.c).
14530 (cursor_row_p): Remove parameter `w', unused since
14531 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14533 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14534 All callers changed.
14536 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14538 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
14540 2011-03-27 Anders Lindgren <andlind@gmail.com>

14543 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
14544 (ns_update_auto_hide_menu_bar): New functions.
14545 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

14549 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14551 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14553 * nsmenu.m (runDialogAt): Remove argument to timer_check.
14555 2011-03-27 Glenn Morris <rgm@gnu.org>
14557 * syssignal.h: Replace RETSIGTYPE with void.
14558 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
14559 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
14560 Replace SIGTYPE with void everywhere.

14564 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14566 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14567 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14569 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14571 * w32.c (read_unc_volume): Use parameter `henum', instead of
14572 global variable `wget_enum_handle'.
14574 * keymap.c (describe_vector): Remove parameters `indices' and
14575 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14587 * xmenu.c (show_help_event, menu_help_callback):
14588 Adjust calls to `show_help_echo'.
14590 * gtkutil.c (xg_maybe_add_timer):
14591 * keyboard.c (readable_events):
14592 * process.c (wait_reading_process_output):
14593 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14595 * insdel.c (adjust_markers_gap_motion):
14596 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

14670 2011-03-23 Julien Danjou <julien@danjou.info>
14672 * term.c (Fsuspend_tty, Fresume_tty):
14673 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14674 * window.c (temp_output_buffer_show):
14675 * insdel.c (signal_before_change):
14676 * frame.c (Fhandle_switch_frame):

14679 * editfns.c (save_excursion_restore):
14680 * cmds.c (internal_self_insert):
14681 * callint.c (Fcall_interactively):
14682 * buffer.c (Fkill_all_local_variables):
14683 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14685 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14686 unconditionally since it does the check itself.
14688 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14690 Fix more problems found by GCC 4.5.2's static checks.
14692 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14693 the first time through the loop, since we know p0 < p1 then.
14694 This also avoids a gcc -Wstrict-overflow warning.
14696 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14697 leading to a memory leak, possible in functions like
14698 load_charset_map_from_file that can allocate an unbounded number
14699 of objects (Bug#8318).
14701 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14702 that could (at least in theory) be that large.
14704 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14705 This is less likely to overflow, and avoids undefined behavior if
14706 overflow does occur. All callers changed. Use strtoul to scan
14707 for the unsigned long integer.
14708 (pint2hrstr): Simplify and tune code slightly.
14709 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14719 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14722 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14724 * process.c (Fmake_network_process): Use socklen_t, not int,
14725 where POSIX says socklen_t is required in portable programs.
14726 This fixes a porting bug on hosts like 64-bit HP-UX, where
14727 socklen_t is wider than int (Bug#8277).
14728 (Fmake_network_process, server_accept_connection):
14729 (wait_reading_process_output, read_process_output):
14732 * process.c: Rename or move locals to avoid shadowing.
14733 (list_processes_1, Fmake_network_process):
14734 (read_process_output_error_handler, exec_sentinel_error_handler):
14735 Rename or move locals.
14736 (Fmake_network_process): Define label "retry_connect" only if needed.
14737 (Fnetwork_interface_info): Fix pointer signedness.

14739 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14740 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14742 Make tparam.h and terminfo.c consistent.
14743 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14744 Include tparam.h instead, since it declares them.
14745 * cm.h (PC): Remove extern decl; tparam.h now does this.
14746 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14747 * terminfo.c: Include tparam.h, to check interfaces.
14748 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14749 (tparam): Adjust signature to match interface in tparam.h;
14750 this removes some undefined behavior. Check that outstring and len
14751 are zero, which they always are with Emacs.
14752 * tparam.h (PC, BC, UP): New extern decls.
14754 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14755 (xftfont_open): Rename locals to avoid shadowing.
14757 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14758 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14759 (OTF_TAG_SYM): Omit macro if not needed.
14760 (ftfont_list): Remove unused local.
14761 (get_adstyle_property, ftfont_pattern_entity):
14762 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
14763 Rename locals to avoid shadowing.
14765 * xfont.c (xfont_list_family): Mark var as initialized.
14767 * xml.c (make_dom): Now static.
14769 * composite.c (composition_compute_stop_pos): Rename local to
14771 (composition_reseat_it): Remove unused locals.
14772 (find_automatic_composition, composition_adjust_point): Likewise.
14773 (composition_update_it): Mark var as initialized.
14774 (find_automatic_composition): Mark vars as initialized,
14775 with a FIXME (Bug#8290).
14777 character.h: Rename locals to avoid shadowing.
14778 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14779 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14780 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14781 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14782 to avoid shadowing.
14784 * textprop.c (property_change_between_p): Remove; unused.
14786 * intervals.c (interval_start_pos): Now static.
14788 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
14790 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
14791 Rename locals to avoid shadowing.
14793 * sound.c (wav_play, au_play, Fplay_sound_internal):
14794 Fix pointer signedness.
14795 (alsa_choose_format): Remove unused local var.
14796 (wav_play): Initialize a variable to 0, to prevent undefined
14797 behavior (Bug#8278).
14799 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14801 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14803 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14804 clobbering (Bug#8298).
14805 * sysdep.c (sys_subshell): Likewise.
14806 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14808 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14809 This should get cleaned up, so that child_setup has the
14810 same signature on all platforms.
14812 * callproc.c (call_process_cleanup): Now static.
14813 (relocate_fd): Rename locals to avoid shadowing.
14815 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14817 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14818 not to be necessary, and produces flickering.
14820 2011-03-20 Glenn Morris <rgm@gnu.org>
14822 * config.in: Remove file.
14824 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14826 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14827 are now in src/globals.h.
14828 (syms_of_minibuf): Remove spurious & from previous change.

14838 * xfaces.c (Fx_load_color_file):
14839 Read color file from absolute filename (bug#8250).
14841 2011-03-19 Juanma Barranquero <lekktu@gmail.com>

14928 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
14929 (Fdefvar): Rewrite so as not to use empty "else".

14943 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14944 some of which prompt warnings from gcc -Wbad-function-cast.
14945 (Fformat_time_string, Fencode_time, Finsert_char):
14946 (Ftranslate_region_internal, Fformat):

14977 avoids undefined behavior in theory.
14979 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14981 Use functions, not macros, for up- and down-casing (Bug#8254).
14982 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14983 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14984 to use the following functions instead of these macros.
14985 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14986 EMACS_INT, since callers assume the returned value fits in int.
14987 (upcase1): Likewise, for UPCASE_TABLE.
14988 (uppercasep, lowercasep, upcase): New static inline functions.
14989 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14998 which gcc can warn about.
14999 (regex_compile, re_match_2_internal): Mark locals as initialized.
15000 (RETALLOC_IF): Define only if needed.
15001 (WORDCHAR_P): Likewise. This one is never needed, but is used
15002 only in a comment talking about a compiler bug, so put inside
15003 the #if 0 of that comment.
15004 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
15005 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
15008 * search.c (boyer_moore): Rename locals to avoid shadowing.

15023 Rename locals to avoid shadowing.
15024 (Fvertical_motion): Mark locals as initialized.
15026 * casefiddle.c (casify_object, casify_region): Now static.
15027 (casify_region): Mark local as initialized.

15031 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
15032 New macros, so that the caller can use some names other than
15033 gcpro1, gcpro2, etc.
15034 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15036 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15037 argument, for consistency with GCPRO2_VAR, etc: it is now the
15038 prefix of the variable, not the variable itself. All uses
15040 * dired.c (directory_files_internal, file_name_completion):
15041 Rename locals to avoid shadowing.
15043 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15044 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15045 dired.c's scmp function, had undefined behavior.
15046 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15047 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15048 * buffer.h: ... to here, because these macros use current_buffer,
15049 and the new implementation with inline functions needs to have
15050 current_buffer in scope now, rather than later when the macros
15052 (downcase, upcase1): New static inline functions.
15053 (DOWNCASE, UPCASE1): Reimplement using these functions.
15054 This avoids undefined behavior in expressions like
15055 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15056 from race conditions in accessing the global variables
15057 case_temp1 and case_temp2.
15058 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15059 * lisp.h (case_temp1, case_temp2): Remove their decls.
15060 * character.h (ASCII_CHAR_P): Move from here ...
15061 * lisp.h: ... to here, so that the inline functions mentioned
15062 above can use them.
15064 * dired.c (directory_files_internal_unwind): Now static.
15066 * fileio.c (file_name_as_directory, directory_file_name):
15067 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
15069 (file_name_as_directory): Use const pointers when appropriate.
15070 (Fexpand_file_name): Likewise. In particular, newdir might
15071 point at constant storage, so make it a const pointer.
15072 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
15073 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15075 (Fset_file_times, Finsert_file_contents, auto_save_error):

15080 to avoid shadowing.
15082 * marker.c (bytepos_to_charpos): Remove; unused.
15084 * lisp.h (verify_bytepos, count_markers): New decls,
15085 so that gcc does not warn that these functions aren't declared.
15087 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
15088 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
15089 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
15090 (copy_text): Remove unused local var.
15092 * filelock.c (within_one_second): Now static.
15093 (lock_file_1): Rename local to avoid shadowing.
15095 * buffer.c (fix_overlays_before): Mark locals as initialized.
15096 (fix_start_end_in_overlays): Likewise. This function should be
15097 simplified by using pointers-to-pointers, but that's a different
15099 (switch_to_buffer_1): Now static.
15100 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15101 (report_overlay_modification): Rename locals to avoid shadowing.
15103 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
15104 Fix pointer signedness issue.
15105 (sys_subshell): Mark local as volatile if checking for lint,
15106 to suppress a gcc -Wclobbered warning that does not seem to be right.
15107 (MAXPATHLEN): Define only if needed.
15109 * process.c (serial_open, serial_configure): Move decls from here ...
15110 * systty.h: ... to here, so that they can be checked.
15112 * fns.c (get_random, seed_random): Move extern decls from here ...
15113 * lisp.h: ... to here, so that they can be checked.
15115 * sysdep.c (reset_io): Now static.
15116 (wait_for_termination_signal): Remove; unused.
15118 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
15119 (copy_keymap_item, append_key, push_text_char_description):
15121 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
15122 (DENSE_TABLE_SIZE): Remove; unused.
15123 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
15124 (describe_map_tree):
15125 Rename locals to avoid shadowing.
15127 * keyboard.c: Declare functions static if they are not used elsewhere.
15128 (echo_char, echo_dash, cmd_error, top_level_2):
15129 (poll_for_input, handle_async_input): Now static.
15130 (read_char, kbd_buffer_get_event, make_lispy_position):
15131 (make_lispy_event, make_lispy_movement, apply_modifiers):
15132 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
15133 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
15134 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
15135 (read_key_sequence, read_char): Mark locals as initialized.

15212 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
15213 These macros can no longer be used for assignment.
15215 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

15271 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
15273 Improve quality of tests for time stamp overflow.
15274 For example, without this patch (encode-time 0 0 0 1 1
15275 1152921504606846976) returns the obviously-bogus value (-948597
15276 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
15277 reports time overflow. See
15278 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
15279 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
