640 * w32.c (init_environment): Change the default values of many
641 environment variables in dflt_envvars[] to NULL, to avoid pushing
642 them into environment when they were not already defined.
643 Remove the code that deletes site-lisp subdirectories from the default
644 value of EMACSLOADPATH, as it is no longer needed.
645 (check_windows_init_file): Now external, not static.

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

656 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
657 any, in the DEFALT argument into the root of the Emacs build or
658 installation tree, as appropriate.
660 * callproc.c (init_callproc_1): Call decode_env_path instead of
661 doing its equivalent by hand.
662 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
663 the code that sets Vexec_path run on MS-Windows.

694 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
695 Remove unnecessary pointer casts.
696 * alloc.c (record_xmalloc): New function.
697 * lisp.h (record_xmalloc): New decl.
698 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
699 more like a function. This is because the pointer cast is not
700 needed. All uses changed.
701 * print.c (print_string, print_error_message): Avoid length recalc.
703 Improve fix for macroexp crash with debugging (Bug#12118).
704 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
705 ARRAY_MARK_FLAG when checking subscripts, because ASET is
706 not supposed to be invoked from the garbage collector.
707 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
708 (gc_aset): New function, which is like ASET but can be
709 used in the garbage collector.

725 headers (most versions of MinGW w32api don't).
726 (get_security_info, create_symbolic_link)
727 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
729 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
730 in the argument file name.

738 with addition of handling of symlinks and support for 'lstat'.
739 If possible, get file's attributes and security information by
740 handle, not by name. Produce S_IFLNK bit for symlinks, when
742 (stat, lstat): New functions, call 'stat_worker'.
743 (symlink, readlink, careadlinkat): Rewritten to create and resolve
744 symlinks when the underlying filesystem supports them.
746 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
748 Fix macroexp crash on Windows with debugging (Bug#12118).
749 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
750 checking subscripts; problem introduced with the recent
751 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
752 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
753 since it's used in non-static inline functions now.
755 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
756 Don't assume buffer size fits in 'int'. Remove unused local.
758 Use C99-style 'extern inline' if available.

776 * composite.c (COMPOSITE_INLINE):
777 * dispnew.c (DISPEXTERN_INLINE):
778 * sysdep.c (SYSTIME_INLINE):
779 Define to EXTERN_INLINE, so that the corresponding functions
780 are compiled into code.
781 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
782 (INLINE_HEADER_END): New macros.
783 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

805 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
807 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
808 This how ASET and AREF are supposed to work, and makes
809 it easier to think about future improvements. See
810 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
811 * charset.h (set_charset_attr): New function.

1303 the fix for 12036 would have avoided some of the problems noted in

1315 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1316 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1317 not be usable in #if. This simplifies things.
1319 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1321 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

1328 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1329 Adjust to changes in lisp.h and emacs.c, by using

1332 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

1339 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1340 (xreload, hook-run, hookpost-run): Remove.
1341 * emacs.c: Include <verify.h>.
1342 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1343 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
1345 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
1346 (gdb_USE_LSB_TAG): New enum constants.
1347 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

1350 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

1365 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
1367 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
1368 add argument, tune behavior, and adjust all callers.

2240 Prefer snprintf to strncpy.
2241 * nsterm.m (ns_term_init):
2242 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2243 * nsterm.m (ns_term_init):
2244 Avoid the need for strncpy, by using build_string or
2245 make_unibyte_string directly. Use dtoastr, not snprintf.
2246 * process.c (Fmake_network_process): Diagnose service names that
2247 are too long, rather than silently truncating them or creating

2265 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
2266 where argument type is known to be a Lisp_Cons.

2279 * lisp.h (make_pure_string): Fix prototype.
2280 (build_pure_c_string): New function, defined as static inline. This
2281 provides a better opportunity to optimize away calls to strlen when
2282 the function is called with compile-time constant argument.
2283 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2284 argument, adjust users accordingly. Use build_pure_c_string where
2286 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2287 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
2288 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
2290 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2292 Avoid calls to strlen in miscellaneous functions.
2293 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
2294 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
2295 * lread.c (openp): Likewise.
2297 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2299 Avoid calls to strlen in path processing functions.
2300 * fileio.c (file_name_as_directory): Add comment. Change to add
2301 srclen argument and return the length of result. Adjust users
2303 (directory_file_name): Fix comment. Change to add srclen argument,
2304 swap 1st and 2nd arguments to obey the common convention.
2305 Adjust users accordingly.
2306 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2308 2012-07-10 Glenn Morris <rgm@gnu.org>
2310 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
2311 Move PENDING_OUTPUT_COUNT definition to configure.
2313 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
2314 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
2315 * s/gnu.h (DATA_START): Move definitions to configure.
2317 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2318 We include usg5-4-common.h, which defines them both.
2320 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2321 O_RDONLY already includes it).
2323 Stop ns builds setting the EMACSLOADPATH environment variable.
2324 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2325 Now it does not set EMACSLOADPATH, just returns the load-path string.
2326 * nsterm.h: Update accordingly.
2327 * lread.c [HAVE_NS]: Include nsterm.h.
2328 (init_lread) [HAVE_NS]: Use ns_load_path.
2329 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
2331 2012-07-09 Glenn Morris <rgm@gnu.org>
2333 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2334 since the included bsd-common.h does so.
2336 Stop ns builds setting the EMACSPATH environment variable.
2337 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2338 (ns_init_paths): Do not set EMACSPATH.
2339 * nsterm.h (ns_exec_path): Add it.
2340 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2343 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2345 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2347 * process.c (wait_reading_process_output): 'waitchannels' was unset
2348 when read_kbd || !NILP (wait_for_cell); fix this.
2350 Add GCC-style 'const' attribute to functions that can use it.
2351 * character.h (char_resolve_modifier_mask):
2352 * keyboard.h (make_ctrl_char):
2353 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
2354 (init_character_once, next_almost_prime, init_fns, init_image)
2355 (flush_pending_output, init_sound):

2360 Declare the dummy function with ATTRIBUTE_CONST.
2361 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2362 Add decls with ATTRIBUTE_CONST.
2364 Minor improvements to make_formatted_string.
2365 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2366 where int is good enough, as vsprintf returns an int.
2367 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2369 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2371 Use make_formatted_string to avoid double length calculation.
2372 * lisp.h (make_formatted_string): New prototype.
2373 * alloc.c (make_formatted_string): New function.
2374 * buffer.c (Fgenerate_new_buffer_name): Use it.
2375 * dbus.c (syms_of_dbusbind): Likewise.
2376 * editfns.c (Fcurrent_time_zone): Likewise.
2377 * filelock.c (get_boot_time): Likewise.
2378 * frame.c (make_terminal_frame, set_term_frame_name)
2379 (x_report_frame_params): Likewise.
2380 * image.c (gs_load): Likewise.
2381 * minibuf.c (get_minibuffer): Likewise.

2394 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
2396 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2398 Move marker debugging code under MARKER_DEBUG.
2399 * marker.c (MARKER_DEBUG): Move marker debugging code under
2400 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2401 for bootstrap with --enable-checking (~3x slowdown reported
2402 by Juanma Barranquero <lekktu@gmail.com>).
2403 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2405 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2407 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2408 See <http://bugs.gnu.org/11825#29>.
2410 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2412 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2413 has no font, use the frame's font. (Bug#11813)
2414 (display_line): Add commentary about displaying truncation glyphs
2416 (produce_special_glyphs): Move here from term.c.
2418 * term.c (produce_special_glyphs): Move to xdisp.c.
2420 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2423 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2425 * xdisp.c (display_line): Avoid warning about implicit declaration
2428 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2430 * lisp.h: Remove empty conditional.
2432 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2434 * lread.c (load_path_check): Now static.
2436 Fix some minor --with-ns problems found by static checking.
2437 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2438 (x_set_font) [!HAVE_X_WINDOWS]:
2439 * image.c (xpm_load_image) [HAVE_NS]:
2440 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2441 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2442 Remove unused local.
2443 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2444 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2445 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2446 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2447 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2448 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2449 Fix pointer signedness problem.
2450 * xfaces.c (FRAME_X_FONT_TABLE):
2451 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2453 2012-07-07 Glenn Morris <rgm@gnu.org>
2455 * lread.c (load_path_check): New function, split from init_lread.
2456 (init_lread): Reorganize. Motivation:
2457 If EMACSLOADPATH is set, check/warn about that rather than the
2458 defaults, which we are not going to use. Hence we can remove
2459 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2460 Don't warn if site-lisp directories are missing.
2461 If not installed, start from a blank load-path, since
2462 PATH_LOADSEARCH refers to the eventual installation directories.
2464 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2466 Support truncation and continuation glyphs on GUI frames, when
2467 fringes are disabled. (Bug#11832)
2468 * xdisp.c (init_iterator): Get dimensions of truncation and
2469 continuation glyphs even if on GUI frames.
2470 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2471 or both, are absent.
2472 (start_display, move_it_in_display_line_to): Handle the case of a
2473 GUI frame without a fringe to display continuation or truncation
2475 (insert_left_trunc_glyphs): Support GUI frames: make sure
2476 truncation glyphs overwrite enough glyphs from the current line to
2477 have sufficient space in pixels.
2478 (display_line): Support truncation and continuation glyphs on GUI
2479 frames. If some spare pixels are left on the line after inserting
2480 the truncation glyphs, fill that space with a stretch glyph of a
2481 suitably computed width.
2483 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2484 produce_glyphs, to support GUI sessions.
2486 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2488 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2490 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2492 Do not require float-time's arg to fit in time_t (Bug#11825).
2493 This works better on hosts where time_t is unsigned, and where
2494 float-time is applied to the (negative) difference between two times.
2495 * editfns.c (decode_time_components): Last arg is now double *,
2496 not int *, and means to store all the result as a double, without
2497 worrying about whether the seconds part fits in time_t.
2498 All callers changed.
2499 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2500 All callers changed.
2501 (Ffloat_time): Do not fail merely because the specified time falls
2502 outside of time_t range.
2504 2012-07-07 Glenn Morris <rgm@gnu.org>
2506 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2512 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2513 Update dependencies.
2515 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2517 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2519 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

2521 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2522 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2523 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2524 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2526 * xfont.c (compare_font_names): Redo to omit the need for casts.
2528 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2530 * xfns.c (Fx_change_window_property): Doc fix.
2531 * w32fns.c (Fx_change_window_property): Doc fix.
2533 * w32fns.c (Fx_window_property): Accept the same arguments as the
2534 X Windows version. Doc fix.
2535 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2537 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2538 Eli Zaretskii <eliz@gnu.org>
2540 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2541 Windows-specific code from nt/config.nt moved here.
2542 Obsolete settings removed.
2544 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2546 * process.c: Avoid unnecessary calls to gettime.
2547 (wait_reading_process_output): Don't get the time of day
2548 when gobbling data immediately and not waiting, as there's no need
2549 for it in that case. This removes a FIXME.
2551 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2553 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2554 is defined (Bug#11768).
2556 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

2559 * marker.c (byte_char_debug_check): Do not perform the check
2560 if buffer is not multibyte.
2561 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2562 Call byte_char_debug_check with correct arguments.
2564 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2566 Compile marker debugging code only if ENABLE_CHECKING is defined.
2567 * marker.c (byte_char_debug_check, count_markers):
2568 Use only if ENABLE_CHECKING is defined.
2569 (byte_debug_flag): Remove.
2570 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2571 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2573 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2575 Avoid code repetition in marker-related functions.
2576 * marker.c (attach_marker): New function.
2577 (Fset_marker, set_marker_restricted, set_marker_both)
2578 (set_marker_restricted_both): Use it.
2579 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2580 Consistently rename charno to charpos.
2581 (marker_position): Add eassert.
2582 (marker_byte_position): Convert to eassert.

2601 * window.c (save_window_save): Likewise.
2603 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2605 Do not use Fdelete_overlay in delete_all_overlays
2606 to avoid redundant calls to unchain_overlay.
2607 * buffer.c (drop_overlay): New function.
2608 (delete_all_overlays, Fdelete_overlay): Use it.
2609 * minibuf.c (get_minibuffer): Fix comment.
2611 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2613 Port to OpenBSD 5.1 amd64.
2614 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2615 This is needed for OpenBSD, and should be harmless on all BSD systems.
2616 Also, include <sys/sysctl.h>, as it should be available on all
2617 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2618 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2619 use p_pid member, not kp_proc.pid.
2621 2012-07-06 Glenn Morris <rgm@gnu.org>
2623 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.

2636 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2638 Omit needless casts involving void * pointers and allocation.
2639 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2640 as the former is more robust if P's type is changed.
2641 Prefer xzalloc to xmalloc + memset 0.
2642 Simplify malloc-or-realloc to realloc.
2643 Don't worry about xmalloc returning a null pointer.
2644 Prefer xstrdup to xmalloc + strcpy.
2645 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2647 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2648 alloca of a constant.
2650 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2652 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2653 hscroll is larger than the line width. Fixes long and futile
2654 looping inside extend_face_to_end_of_line (on a TTY) producing
2655 glyphs that are not needed and thrown away.
2657 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

2685 * xdisp.c (window_hscroll_limited): New function.
2686 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2687 coordinates when window's hscroll is set to insanely large
2690 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2692 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

2753 * fileio.c (time_error_value): Check the right error number.
2754 Problem reported by Troels Nielsen in
2755 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2757 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2759 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2760 This should be fixed in a better way; see Eli Zaretskii in
2761 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2762 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2764 * fileio.c (time_error_value): Rename from special_mtime.
2765 The old name's problems were noted by Eli Zaretskii in
2766 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2768 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2769 This variable's comment says Emacs needs at least one GDB-visible
2770 symbol of type enum pvec_type, to work around GDB problems.
2771 The symbol's value doesn't matter.
2773 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2774 that causes compilation to fail on pre-C99 compilers.
2776 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2778 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2779 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2781 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2783 * buffer.c (init_buffer_once): Fix initialization of
2784 headers for buffer_defaults and buffer_local_symbols.
2785 Reported by Juanma Barranquero <lekktu@gmail.com>.
2787 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2789 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2790 * lisp.h (enum pvec_type): Use fewer bits.
2791 (PSEUDOVECTOR_SIZE_BITS): New constant.
2792 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2793 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2794 change in pvec_type.
2795 (PSEUDOVECTOR_TYPEP): New macro.
2796 (TYPED_PSEUDOVECTORP): Use it.
2797 * fns.c (internal_equal): Adapt code to extract pvectype.
2798 * emacs.c (gdb_pvec_type): Update type.
2799 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2800 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2801 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2802 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2803 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2804 abusing vector->header.next.nbytes.
2805 (live_vector_p): Use PVEC_TYPE.
2806 (mark_object): Adapt code to extract pvectype. Use switch.
2808 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2810 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2811 Tighten new eassert a bit.
2813 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2815 Fix compilation with --enable-gcc-warnings and -O1
2817 * doprnt.c (doprnt): Change type of tem to int, initialize
2818 to avoid compiler warning. Add eassert.
2819 * search.c (simple_search): Initialize match_byte to avoid
2820 compiler warning. Add eassert.
2822 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2824 Avoid weird behavior with large horizontal scrolls.
2825 Without this change, for example, large hscroll values would
2826 mess up Emacs's display on Fedora 15 x86, presumably due to
2827 overflows in int calculations in the display code.
2828 Also, if buffers had long lines, Emacs would freeze.
2829 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2830 (set_window_hscroll): New function, containing the old guts of
2831 Fset_window_hscroll. Return the clipped value.
2832 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2833 This avoids the need to check against PTRDIFF_MAX.
2835 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2837 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2839 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2841 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2843 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2844 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2845 since GCC 4.4.6 issues a bogus warning for them.
2847 Fix bugs in file timestamp newness comparisons.
2848 * fileio.c (Ffile_newer_than_file_p):
2849 * lread.c (Fload): Use full timestamp resolution of files,
2850 not just the 1-second resolution, so that files that are only
2851 slightly newer still count as newer.
2852 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2853 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2855 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2857 * fileio.c: Improve handling of file time marker. (Bug#11852)
2858 (special_mtime): New function.
2859 (Finsert_file_contents, Fverify_visited_file_modtime):
2860 Use it to set special mtime values consistently.
2862 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2864 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2865 marker for non-existing file. (Bug#11852)
2867 2012-07-03 Glenn Morris <rgm@gnu.org>
2869 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2870 and did not make it into globals.h).
2872 2012-07-03 Tom Tromey <tromey@redhat.com>
2874 * window.c (Fset_window_margins, Fset_window_fringes)
2875 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2876 * textprop.c (Fprevious_property_change): No longer static.

2910 2012-07-03 Glenn Morris <rgm@gnu.org>
2912 * lisp.h (Frandom): Make it visible to C.
2913 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2914 buffer for invisible buffers. (Bug#1229)
2916 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2918 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2919 values which aren't power of 2.
2920 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
2921 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2924 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2926 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2928 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2930 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2932 * alloc.c (allocate_vector_block): Remove redundant
2933 calls to mallopt if DOUG_LEA_MALLOC is defined.
2934 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2935 avoid calls to mallopt if zero_vector is returned.
2937 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2939 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2940 is enabled, avoid dereferencing NULL current_sblock if
2943 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2945 Cleanup basic buffer management.
2946 * buffer.h (struct buffer): Change layout to use generic vector
2947 marking code. Fix some comments. Change type of 'clip_changed'
2948 to bitfield. Remove unused #ifndef old.
2949 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2950 (GET_OVERLAYS_AT): Fix indentation.
2951 (for_each_per_buffer_object_at): New macro.
2952 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2954 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2955 * alloc.c (allocate_buffer): Adjust to match new layout of
2956 struct buffer. Fix comment.
2957 (mark_overlay): New function.
2958 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2959 Lisp area of struct buffer.
2960 (mark_object): Use it. Adjust marking of misc objects
2961 and related comments.
2963 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2965 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2966 wrapper that is not needed because the wrapped code is a no-op (zero
2967 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2968 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2970 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2972 * alloc.c (mark_buffer): Simplify. Remove prototype.
2973 (mark_object): Add comment. Reorganize marking of vector-like
2974 objects. Use CHECK_LIVE for all vector-like objects except buffers
2975 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
2976 Avoid redundant calls to mark_vectorlike for bool vectors.
2978 2012-06-30 Glenn Morris <rgm@gnu.org>
2980 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2982 * epaths.in (PATH_SITELOADSEARCH): New.
2983 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2984 This is rather than relying on --enable-locallisppath elements
2985 having "site-lisp" in their names. (Bug#10208#25, 11658)
2987 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2989 * w32proc.c (sys_select): Accept and ignore one more argument.
2991 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2993 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2994 (pselect) [!MS_DOS]: Redirect to sys_select.
2996 * sysdep.c: Don't include dos.h and dosfns.h.
2998 * process.c (sys_select):
2999 * msdos.c (sys_select): Accept one more argument and ignore it.
3001 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
3002 adapt data types and code to that.
3005 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
3006 which clashes with the gnulib function of the same name.
3008 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3010 * font.c (font_style_to_value, font_style_symbolic)
3011 (font_prop_validate_style): Add type checks for values in
3014 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3016 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3019 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3021 * xdisp.c (try_window_id): Undo last change.
3023 * w32.c (getwd): Adjust commentary about startup_dir.
3024 (init_environment): Always call sys_access, even in non-MSVC
3025 builds. Don't chdir to the directory of the Emacs executable.
3026 This undoes code from 1997 which was justified by the need to
3027 "avoid conflicts when removing and renaming directories". But its
3028 downside was that every relative file name was being interpreted
3029 relative to the directory of the Emacs executable, which can never
3030 be TRT. In particular, it broke sys_access when called with
3031 relative file names.
3032 (sys_access): Map GetLastError to errno.
3034 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3036 * window.h (struct window): Change type of 'fringes_outside_margins'
3037 to bitfield. Fix comment. Adjust users accordingly.
3038 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
3040 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3043 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
3045 * gnutls.c (emacs_gnutls_handshake):
3046 Add QUIT to make the loop interruptible.
3048 2012-06-29 Glenn Morris <rgm@gnu.org>
3050 * charset.c (init_charset): Make lack of etc/charsets fatal.
3052 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3054 * editfns.c (region_limit): Fix type mismatch.
3056 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3058 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3059 undefined. Convert from xassert to eassert.
3060 * nsmenu.m: Convert from xassert to eassert.
3061 * nsterm.m: Likewise.
3063 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3065 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3067 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3069 Avoid integer overflow on scroll-left and scroll-right.
3070 * window.c (HSCROLL_MAX): New macro.
3071 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3072 overflow when requested scroll falls outside ptrdiff_t range.
3074 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3076 * window.h (struct window): Change type of 'hscroll',
3077 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3078 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3079 Adjust users accordingly.
3080 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3081 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3082 from EMACS_INT to ptrdiff_t.
3083 (make_window): Omit redundant initialization.
3085 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

3089 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3091 * window.h (struct window): Change type of 'use_time' and
3092 'sequence_number' from Lisp_Object to int.

3154 avoid GCC warning about unused macro.
3156 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3158 * alloc.c (allocate_string): Omit intervals initialization.
3159 * alloc.c (make_uninit_multibyte_string): Initialize intervals
3160 as in make_pure_string and make_pure_c_string.
3162 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3164 * alloc.c (allocate_string): Fix last change.
3166 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

3216 * alloc.c: Remove build_string.
3217 * lisp.h: Define build_string as static inline. This provides
3218 a better opportunity to optimize away calls to strlen when the
3219 function is called with compile-time constant argument.
3220 * image.c (imagemagick_error): Convert to build_string.
3221 * w32proc.c (sys_spawnve): Likewise.

3224 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3226 Use sprintf return value instead of invoking strlen on result.
3227 In the old days this wasn't portable, since some sprintf
3228 implementations returned char *. But they died out years ago and
3229 Emacs already assumes sprintf returns int.
3230 Similarly for float_to_string.
3231 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

3239 Use sprintf or float_to_string result to avoid need to call strlen.
3240 * data.c (Fnumber_to_string):
3241 Use make_unibyte_string, since the string must be ASCII.
3242 * lisp.h, print.c (float_to_string): Now returns int length.
3243 * term.c (produce_glyphless_glyph):
3244 Use sprintf result rather than recomputing it.

3345 * keyboard.c (kbd_buffer_get_event):
3346 * process.c (Faccept_process_output):
3347 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3348 This improves on the previous patch, which introduced a bug
3349 when time_t is unsigned and as wide as intmax_t.
3350 See <http://bugs.gnu.org/9000#51>.

3413 Don't assume EMACS_TIME and struct timeval are the same type.
3415 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3417 Support higher-resolution time stamps (Bug#9000).
3418 The time stamps are only nanosecond-resolution at the C level,
3419 since that's the best that any real-world system supports now.
3420 But they are picosecond-resolution at the Lisp level, as that's
3421 easy, and leaves room for future OS improvements.
3423 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3426 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3427 Don't get current time unless it's needed.
3429 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3430 now provides it if it's absent.
3431 (start_atimer): Port to higher-res time stamps.
3432 Check for time stamp overflow. Don't get current time more
3433 often than is needed.
3435 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3436 Include systime.h, not time.h.
3437 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3439 * dired.c: Include stat-time.h.
3440 (Ffile-attributes): File times now have higher resolution.

3443 (struct image): Timestamp now has higher resolution.
3445 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3446 has at least microseconds now. All uses removed.
3447 (update_frame, update_single_window, update_window, update_frame_1)
3448 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3450 * editfns.c (time_overflow): Now extern.
3451 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3452 (float-time, Fformat_time_string, Fcurrent_time_string)
3453 (Fcurrent_time_zone): Accept and generate higher-resolution
3455 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3456 (decode_time_components, lisp_seconds_argument): New functions.
3457 (make_time): Now static.
3458 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3459 Report an error if the time is invalid, rather than having the caller
3462 * fileio.c: Include <stat-time.h>
3463 (Fcopy_file): Copy higher-resolution time stamps.
3464 Prefer to set the time stamp via a file descriptor if that works.
3465 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3466 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3467 (Fvisited_file_modtime, Fset_visited_file_modtime):
3468 Support higher-resolution time stamps.
3470 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3472 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3474 * image.c (prepare_image_for_display, clear_image_cache)
3475 (lookup_image): Port to higer-resolution time stamps.
3477 * keyboard.c (start_polling, bind_polling_period):
3478 Check for time stamp overflow.
3479 (read_char, kbd_buffer_get_event, timer_start_idle)
3480 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3481 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3482 Port to higher-resolution time stamps. Do not assume time_t is signed.
3483 (decode_timer): New function. Timers are now vectors of length 9,
3484 not 8, to accommodate the picosecond component.
3485 (timer_check_2): Use it.
3487 * nsterm.m (select_timeout, timeval_subtract): Remove.
3488 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3489 as they're a bit more accurate and handle overflow better.
3490 (ns_select): Change prototype to be compatible with pselect.
3491 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3492 * nsterm.h (ns_select): Adjust prototype.
3494 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3495 us-resolution time stamps.
3496 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3498 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3500 * lisp.h (time_overflow): New decl.
3501 (wait_reading_process_output): First arg is now intmax_t, not int,
3502 to accommodate larger waits.
3504 * process.h (struct Lisp_Process.read_output_delay):
3505 Now counts nanoseconds, not microseconds.
3506 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3508 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3509 (wait_reading_process_output):
3510 Port to ns-resolution time stamps.
3511 (Faccept_process_output, wait_reading_process_output):
3512 Check for time stamp overflow. Do not assume time_t is signed.
3513 (select_wrapper): Remove; we now use pselect.
3514 (Fprocess_attributes): Now generates ns-resolution time stamps.
3516 * sysdep.c: Include utimens.h. Don't include utime.h
3517 or worry about struct utimbuf; gnulib does that for us now.
3518 (gettimeofday): Remove; gnulib provides a substitute.
3519 (make_timeval): New function.
3520 (set_file_times): Now sets ns-resolution time stamps.
3521 New arg FD; all uses changed.
3522 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3523 (system_process_attributes):
3524 Now returns ns-resolution time stamp. All uses changed.
3525 Check for time stamp overflow.
3527 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3528 provides a substitute now.
3530 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3531 since it guarantees struct timespec.
3532 (EMACS_TIME): Now struct timespec, so that we can support
3533 ns-resolution time stamps.
3534 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3535 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3536 (EMACS_USECS): Remove.
3537 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3538 so multiply the arg by 1000 before storing it.
3539 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3541 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3542 Port to ns-resolution time stamps.
3543 (EMACS_TIME_NEG_P): Remove; replaced by....
3544 (EMACS_TIME_SIGN): New macro.
3545 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3546 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3547 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3548 (make_timeval, make_lisp_time, decode_time_components): New decls.
3549 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3550 that it mishandled time_t overflow. You can't compare by subtracting!
3551 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3552 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3554 * term.c: Include <sys/time.h>.
3555 (timeval_to_Time): New function, for proper overflow wraparound.
3556 (term_mouse_position, term_mouse_click): Use it.
3558 * undo.c (record_first_change): Support higher-resolution time stamps
3560 (Fprimitive_undo): Use them when restoring time stamps.
3562 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3563 (w32_get_internal_run_time):
3564 Port to higher-resolution Emacs time stamps.
3565 (ltime): Now accepts single 64-bit integer, as that's more convenient
3568 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3570 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3571 for compatibility with pselect. Support ns-resolution time stamps.
3573 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3575 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3576 Check for time stamp overflow, and support ns-resolution time stamps.
3578 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3579 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3580 (timeval_subtract): Remove; no longer needed.
3581 (XTflash, XTring_bell, x_wait_for_event):
3582 Port to ns-resolution time stamps. Don't assume time_t is signed.
3584 2012-06-22 Chong Yidong <cyd@gnu.org>

3588 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3590 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3591 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3592 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3593 staticidx goes up to 1597 out of 1600 = 0x640.)
3595 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3597 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3598 Otherwise, the umask might be mistakenly 0 while handling input signals.
3600 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3602 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

3608 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3609 access to `contents' member of Lisp_Vector objects with AREF and ASET
3612 2012-06-19 Chong Yidong <cyd@gnu.org>
3614 * frame.c (delete_frame): When selecting a frame on a different
3615 text terminal, do not alter the terminal's top-frame.

3618 frame's selected window and its terminal's top-frame.
3619 (unwind_format_mode_line): Restore them.
3620 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3622 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3623 since tty frames can be explicitly named.
3624 (prepare_menu_bars): Likewise.
3626 * term.c (Ftty_top_frame): New function.
3628 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3630 Port byte-code-meter to modern targets.
3631 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3632 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3633 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3634 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3635 (METER_1, METER_2): Simplify.
3637 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3639 * data.c (Fdefalias): Return `symbol' (bug#11686).
3641 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3643 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3644 gets killed during executing of this function (Bug#11665).
3645 Try to always return Qt when the buffer has been actually killed.
3646 (Vkill_buffer_query_functions): In doc-string say that functions
3647 run by this hook should not change the current buffer.
3649 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3651 Fix recently-introduced process.c problems found by static checking.
3652 * process.c (write_queue_push, write_queue_pop, send_process):

3654 (write_queue_pop): Fix pointer signedness problem.
3655 (send_process): Remove unused local.
3657 2012-06-17 Chong Yidong <cyd@gnu.org>

3660 frames that are not on top.
3662 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
3664 * process.c (make_process): Initialize write_queue.
3665 (write_queue_push, write_queue_pop): New functions.
3666 (send_process): Use them to maintain correct ordering of process
3669 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3671 * lisp.h (eassert): Assume C89 or later.
3672 This removes the need for CHECK.
3673 (CHECK): Remove. Its comments about always evaluating its
3674 argument were confusing, as 'eassert' typically does not evaluate
3677 * coding.c (produce_chars): Use ptrdiff_t, not int.
3679 * xterm.c (x_draw_underwave): Check for integer overflow.
3680 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
3682 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
3684 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

3867 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3868 Use an inline function on all platforms when using the union type,
3869 since this is simpler and 'static inline' can be used portably

3984 Block-based vector allocation of small vectors.

4013 * doprnt.c (doprnt): Truncate multibyte char correctly.
4014 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4015 would mishandle a string argument "Xc" if X was a multibyte

4070 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
4071 Convert pctcpu and pctmem to Lisp float properly.
4072 Let the compiler fold better, as 100.0/0x8000 is exact.

4091 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
4092 fields from Lisp_Object to bitfield. Adjust users accordingly.

4100 and 'double' in a couple of places.
4102 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4104 * xdisp.c (handle_stop): Detect whether we have overlay strings
4105 loaded by testing it->current.overlay_string_index to be
4106 non-negative, instead of checking whether n_overlay_strings is
4107 positive. (Bug#11587)

4117 * search.c (search_buffer): Remove calls to
4118 r_alloc_inhibit_buffer_relocation, as it is now called by
4119 maybe_unify_char, which was the cause of relocation of buffer text
4122 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4124 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4125 for the duration of call to load_charset, to avoid problems with
4126 callers of maybe_unify_char that access buffer text through C
4129 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4130 decrement the inhibition flag, instead of just setting or
4133 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>

4136 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

4140 (gray_bitmap_bits): Remove; no longer needed.

4182 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4184 Do not create empty overlays with the evaporate property (Bug#9642).
4185 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4186 Bug#9642, but explicitly check that the buffer the overlay would
4187 be moved to is live and rearrange lines to make sure that errors
4188 will not put the overlay in an inconsistent state.
4189 (Fdelete_overlay): Cosmetics.
4191 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4193 * w32term.c (my_bring_window_to_top): New function.
4194 (x_raise_frame): Use handle returned by DeferWindowPos, which
4195 could be different from the original one.

4199 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4200 by calling BringWindowToTop.
4202 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4203 (WM_EMACS_END): Increase by one.
4205 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4207 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4208 This avoids undefined behavior that might cause the eassert
4209 to not catch an out-of-range value.
4211 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4213 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4214 Update dependencies.

4223 when referring to sectname field in printf format.
4225 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4227 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4228 Only r_alloc_inhibit_buffer_relocation needed to be added;
4229 the others were already declared.
4231 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4232 before checking whether it's out of range. Put the check inside
4234 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4236 2012-05-27 Ken Brown <kbrown@cornell.edu>
4238 * callproc.c (Fcall_process): Restore a line that was accidentally
4239 commented out in the 2011-02-13 change (bug#11547).
4241 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4243 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4244 defined on ralloc.c.
4246 * buffer.c [REL_ALLOC]: Remove prototypes of
4247 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4248 they are now on lisp.h.
4250 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4252 * search.c (search_buffer): Use it to inhibit relocation of buffer
4253 text while re_search_2 is doing its job, because re_search_2 is
4254 passed C pointers to buffer text. (Bug#11519)
4256 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4259 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4260 state after an additional call to move_it_in_display_line_to, keep
4261 the values of it->max_ascent and it->max_descent found for the
4263 (pos_visible_p): Revert the comparison against bottom_y to what it
4264 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4267 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4269 Fix coding-related core dumps with gcc -ftrapv.
4270 The code was computing A - B, where A and B are pointers, and B is
4271 random garbage. This can lead to core dumps on platforms that
4272 have special pointer registers, and it also leads to core dumps on
4273 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4274 A - B only when B is initialized properly.
4275 * coding.c (coding_set_source, coding_set_destination): Return void.
4276 (coding_change_source, coding_change_destinations): New functions,
4277 with the old behaviors of coding_set_source and coding_set_destination.
4278 All callers that need an offset changed to use these new functions.
4280 2012-05-26 Glenn Morris <rgm@gnu.org>
4282 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4284 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4286 Extend mouse support on W32 text-mode console.
4287 * xdisp.c (draw_row_with_mouse_face):
4288 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4290 * w32console.c: Include window.h.
4291 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4293 (initialize_w32_display): Initialize mouse-highlight data.
4295 * w32inevt.c: Include termchar.h and window.h.
4296 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4297 moves, call note_mouse_highlight. If help_echo changed, call
4298 gen_help_event to produce help-echo message in the echo area.
4299 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4302 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4304 * lread.c (read1): Simplify slightly to avoid an overflow warning
4305 with GCC 4.7.0 on x86-64.
4307 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4309 * bidi.c (bidi_mirror_char): Revert last change: an int is
4310 definitely wide enough here.
4312 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4314 Fix integer width and related bugs (Bug#9874).

4322 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4324 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4325 (allocate_pseudovector):
4326 Use int, not EMACS_INT, where int is wide enough.
4327 (inhibit_garbage_collection, Fgarbage_collect):
4328 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4329 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4330 int might not be wide enough.
4331 (bidi_cache_search, bidi_cache_find, bidi_init_it)

4335 (bidi_level_of_next_char, bidi_move_to_visually_next):
4336 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4337 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4338 (Fkill_buffer, Fset_buffer_major_mode)

4345 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4346 (Foverlay_recenter, last_overlay_modification_hooks_used)
4347 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4348 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4349 (validate_region): Omit unnecessary test for b <= e,
4350 since that's guaranteed by the previous test.
4351 (adjust_overlays_for_delete): Avoid pos + length overflow.
4352 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4353 (report_overlay_modification):
4354 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4355 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4356 Omit pointer cast, which isn't needed anyway, and doesn't work
4357 after the EMACS_INT -> ptrdiff_t change.
4358 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4359 * buffer.h: Adjust decls to match defn changes elsewhere.

4364 not int, to avoid needless 32-bit limit on 64-bit hosts.
4365 (exec_byte_code): Use tighter memory-full test, one that checks
4366 for alloca overflow. Don't compute the address of the object just
4367 before an array, as that's not portable. Use EMACS_INT, not
4368 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4369 * callint.c (Fcall_interactively):
4370 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

4381 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4382 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4383 (casify_object): Avoid integer overflow when overallocating buffer.
4384 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4385 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4386 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4387 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4388 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4389 integers are now checked earlier. All uses replaced with XINT.
4391 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4392 For CCL_MapSingle, check that content and value are in int range.
4393 (ccl_driver, Fregister_code_conversion_map):
4394 Check that Vcode_version_map_vector is a vector.
4395 (resolve_symbol_ccl_program): Check that vector header is in range.
4396 Always copy the vector, so that we can check its contents reliably
4397 now rather than having to recheck each instruction as it's being
4398 executed. Check that vector words fit in 'int'.
4399 (ccl_get_compiled_code, Fregister_ccl_program)
4400 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4401 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4402 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4403 contents are in range.
4404 (Fccl_execute_on_string): Check that status is in range.
4405 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4406 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4407 Accept and return EMACS_INT, not int, because callers can pass values
4409 (c_string_width, strwidth, lisp_string_width, chars_in_text)

4412 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4413 (string_escape_byte8, Fget_byte):
4414 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4415 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4416 avoid mishandling large integers.
4417 * character.h: Adjust decls to match defn changes elsewhere.

4426 (Fdefine_charset_internal): Check ranges here, more carefully.
4427 Don't rely on undefined behavior with signed left shift overflow.
4428 Don't assume unsigned int fits into fixnum, or that fixnum fits
4429 into unsigned int. Don't require max_code to be a valid fixnum;
4430 that's not true for gb10830 4-byte on a 32-bit host. Allow
4431 invalid_code to be a cons, for the same reason. Require code_offset
4432 to be a character. Avoid int overflow if max_char is close
4434 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4435 this is intended anyway and avoids some undefined behavior.
4436 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4437 INDEX_TO_CODE_POINT, as that's what it expects.
4438 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4439 * charset.h (DECODE_CHAR): Return int, not unsigned;
4440 this is what was intended anyway, and it avoids undefined behavior.
4441 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4442 integer-overflow issues.
4443 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4444 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4445 where the argument is EMACS_INT, and this behavior is not intended.
4446 * chartab.c (Fmake_char_table, Fset_char_table_range)
4447 (uniprop_get_decoder, uniprop_get_encoder):
4448 Don't assume fixnum fits in int.
4449 * cmds.c (move_point): New function, that does the gist of
4450 Fforward_char and Fbackward_char, but does so while checking
4451 for integer overflow more accurately.
4452 (Fforward_char, Fbackward_char): Use it.
4453 (Fforward_line, Fend_of_line, internal_self_insert)
4454 (internal_self_insert):
4455 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4456 Fix a FIXME, by checking for integer overflow when calculating
4457 target_clm and actual_clm.

4492 Don't access memory outside of the args array.
4493 (Fdefine_coding_system_internal): Check for charset-id overflow.

5254 already have overlays loaded.
5255 (handle_single_display_spec): Before returning without displaying
5256 fringe bitmap, synchronize the bidi iterator with the main display
5257 iterator, by calling iterate_out_of_display_property.

5259 testing that it->string is a Lisp string.
5260 (get_next_display_element): When the current object is exhausted,

5266 the display vector. (Bug#11417)
5267 (pos_visible_p): Don't report a position visible when move_it_to
5268 stopped at the last line of window, which happens to be scanned

5273 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5274 and right-margin display specs even if the spec is invalid or we
5275 are on a TTY, and thus unable to display on the fringes.
5276 That's because the text with the property will not be displayed anyway,
5277 so we need to signal to the caller that this is a "replacing"
5278 display spec. This fixes display when the spec is invalid or we
5281 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5283 * unexaix.c (make_hdr): Fix typo in prototype.

5313 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5314 Update dependencies.
5316 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5318 * xgselect.c (xg_select): Put maxfds+1 into a var.
5319 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5321 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5323 2012-05-10 Dave Abrahams <dave@boostpro.com>
5325 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5326 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5328 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5330 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5331 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5332 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5333 Initialize xd_registered_buses.
5335 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5337 Untag more efficiently if USE_LSB_TAG.
5338 This is based on a proposal by YAMAMOTO Mitsuharu in
5339 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5340 For an admittedly artificial (nth 8000 longlist) benchmark on
5341 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5342 Emacs's overall text size by 1%.
5343 * lisp.h (XUNTAG): New macro.
5344 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5345 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5346 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5347 * eval.c (Fautoload):
5348 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5349 * frame.h (XFRAME): Use XUNTAG.
5351 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5352 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5353 Remove unportable assumptions about print widths of types like
5355 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5356 intptr_t when converting between pointer and integer, to avoid GCC
5357 warnings about wrong width.
5359 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5361 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5362 stack for each reader_thread, instead of defaulting to 8MB
5363 determined by the linker. This avoids failures in creating
5364 subprocesses on Windows 7, see the discussion in this thread:
5365 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5367 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5369 Fix up display of the *Minibuf-0* buffer in the mini window.
5370 * keyboard.c (read_char): Don't clear the echo area if there's no
5372 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5373 contents of *Minibuf-0*) if there's no message displayed in its stead.
5375 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5377 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5380 2012-05-06 Chong Yidong <cyd@gnu.org>
5382 * lisp.mk (lisp): Update.
5384 2012-05-05 Jim Meyering <meyering@redhat.com>
5386 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5388 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5390 * data.c (PUT_ERROR): New macro.
5391 (syms_of_data): Use it. Add new error type `user-error'.
5392 * undo.c (user_error): New function.
5393 (Fprimitive_undo): Use it.
5394 * print.c (print_error_message): Adjust print style for `user-error'.
5395 * keyboard.c (user_error): New function.
5396 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5398 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5400 Do not limit current-time-string to years 1000..9999.
5401 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5402 (Fcurrent_time_string): Support any year that is supported by the
5403 underlying localtime representation. Don't use asctime, as it
5404 has undefined behavior for years outside the range -999..9999.
5406 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5408 Fix race conditions involving setenv, gmtime, localtime, asctime.
5409 Without this fix, interrupts could mess up code that uses these
5410 nonreentrant functions, since setting TZ invalidates existing
5411 tm_zone or tzname values, and since most of these functions return
5412 pointers to static storage.
5413 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5414 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5415 Grow the critical sections to include not just invoking
5416 localtime/gmtime, but also accessing these functions' results
5417 including their tm_zone values if any, and any related TZ setting.
5418 (format_time_string): Last arg is now struct tm *, not struct tm **,
5419 so that the struct tm is saved in the critical section.
5420 All callers changed. Simplify allocation of initial buffer, partly
5421 motivated by the fact that memory allocation needs to be outside
5422 the critical section.
5424 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5426 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5427 with RESET_INTERVAL.
5429 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5430 Remove duplicated buffer name initialization.
5432 2012-05-02 Jim Meyering <jim@meyering.net>
5434 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5436 * xfns.c (x_window): Use xstrdup (Bug#11375).
5438 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5440 * xdisp.c (pos_visible_p): If already at a newline from the
5441 display string before the 'while' loop, don't walk back the glyphs
5442 from it3.glyph_row. Solves assertion violation when the display
5443 string begins with a newline (egg.el). (Bug#11367)
5445 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5447 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5450 2012-05-01 Glenn Morris <rgm@gnu.org>
5452 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5453 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5454 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5455 All were removed before 23.1.
5457 * dispnew.c: Remove HAVE_LIBNCURSES test;
5458 it is always true on relevant platforms.
5460 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5461 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5463 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5465 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5467 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5468 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5471 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5473 Do not avoid creating empty evaporating overlays (Bug#9642).
5474 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5475 That is, do not delete an evaporating overlay if it becomes
5476 empty after its bounds are adjusted to fit within its buffer.
5477 This fix caused other problems, and I'm reverting it until we get
5478 to the bottom of them.
5480 2012-04-27 Chong Yidong <cyd@gnu.org>
5482 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5484 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5486 * xdisp.c (pos_visible_p): If the window start position is beyond
5487 ZV, start the display from buffer beginning. Prevents assertion
5488 violation in init_iterator when the minibuffer window is scrolled
5491 * window.c (window_scroll_pixel_based): Likewise.
5493 2012-04-27 Chong Yidong <cyd@gnu.org>
5495 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5497 2012-04-27 Glenn Morris <rgm@gnu.org>
5499 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5500 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5502 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5504 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5505 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5507 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5509 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5510 display element, check also the underlying string or buffer
5511 character. (Bug#11341)
5513 * w32menu.c: Include w32heap.h.
5514 (add_menu_item): If the call to AppendMenuW (via
5515 unicode_append_menu) fails, disable Unicode menus only if we are
5516 running on Windows 9X/Me.
5518 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5520 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5521 (xgetint): Add missing shift for LSB tags.
5523 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5525 * keyboard.c (read_char): Don't wipe echo area for select window
5526 events: These might get delayed via `mouse-autoselect-window'
5529 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5531 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5532 manipulation of :loaded-from data.
5534 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5536 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5537 now a cons (bug#11311).
5539 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5541 Do not create empty overlays with the evaporate property (Bug#9642).
5542 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5543 if it becomes empty after its bounds are adjusted to fit within
5544 its buffer. Without this fix, in a nonempty buffer (let ((o
5545 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5546 yields an empty overlay that has the evaporate property, which is
5547 not supposed to happen.
5549 Fix minor GTK3 problems found by static checking.
5550 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5551 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5552 (struct _EmacsFixedClass, emacs_fixed_get_type):

5562 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5564 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5565 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5567 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5569 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5570 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5571 (__malloc_size_t, __malloc_ptrdiff_t):
5572 Remove. All uses removed, replaced by the definiens if needed,
5573 since we can assume C89 or better now.
5574 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5575 (protect_malloc_state, align, get_contiguous_space)
5576 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5582 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5583 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5584 Define using prototypes, not old style.
5585 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5586 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5587 (align): Don't assume that signed integer overflow wraps around.
5588 Omit unused local var.
5589 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5590 (_free_internal_nolock, memalign, mallochook, reallochook):

5596 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5598 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

5649 * alloc.c: Handle unusual debugging option combinations.
5650 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5651 since the two debugging options are incompatible.

5664 * sysdep.c [__FreeBSD__]: Minor cleanups.
5665 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5666 Use Emacs indenting style more consistently. Avoid some casts.
5667 Use 'double' consistently rather than mixing 'float' and 'double'.

5708 farther than the first row after the header line, if any.
5709 Don't consider the header-line row as "partially visible", even if
5710 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

5763 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
5764 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
5765 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
5766 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
5767 [REL_ALLOC]: ... to here, to check interface.
5768 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5769 Remove decls. This fixes an "It stinks!".
5771 * alloc.c (which_symbols): Fix alignment issue / type clash.
5773 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5775 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
5776 (struct Lisp_Misc_Any): Likewise.
5777 (struct Lisp_Free): Likewise.
5778 * alloc.c (union aligned_Lisp_Symbol): Define.
5779 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
5780 aligned_Lisp_Symbol instead of struct Lisp_Symbol.

5782 (MARKER_BLOCK_SIZE, struct marker_block): Use union
5783 aligned_Lisp_Misc instead of union Lisp_Misc.
5784 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
5786 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5788 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5789 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5790 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5791 * s/netbsd.h, s/sol2-6.h:
5792 Remove definition of GC_MARK_STACK, since the default now works.
5793 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5794 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5795 no longer the default.
5796 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5798 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5800 * lread.c (lisp_file_lexically_bound_p):
5801 Fix hang at ";-*-\n" (bug#11238).

5808 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5810 * nsterm.m (constrainFrameRect): Always constrain when there is only
5811 one screen (Bug#10962).
5813 2012-04-13 Ken Brown <kbrown@cornell.edu>
5815 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
5817 2012-04-13 Reuben Thomas <rrt@sc3d.org>
5819 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
5821 2012-04-11 Daniel Colascione <dancol@dancol.org>
5823 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5824 against is gone. It's better to use vfork now so that when Cygwin
5825 gains a new, working vfork, we use it automatically (bug#10398).
5827 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5829 * window.c (save_window_save): Obey window-point-insertion-type.
5831 2012-04-11 Glenn Morris <rgm@gnu.org>
5833 * Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.
5835 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5837 * alloc.c (lisp_align_malloc): Remove unneeded prototype.
5839 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
5841 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
5842 (force_quit_count): New var.
5843 (handle_interrupt): Use it.
5845 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5847 * w32.c (w32_delayed_load): Record the full path of the library
5848 being loaded (bug#10424).
5850 2012-04-09 Glenn Morris <rgm@gnu.org>
5852 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5853 not just in the obarray, before snarfing them. (Bug#11036)
5855 * Makefile.in ($(leimdir)/leim-list.el):
5856 Pass EMACS rather than BUILT_EMACS.
5858 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5860 * process.c (make_process):
5861 * process.h: Add integer `gnutls_handshakes_tried' member to
5864 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5865 Add convenience `GNUTLS_LOG2i' macro.
5867 * gnutls.c (gnutls_log_function2i): Convenience log function.
5868 (emacs_gnutls_read): Use new log functions,
5869 `gnutls_handshakes_tried' process member, and
5870 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5871 attempts per process (connection).
5873 2012-04-09 Chong Yidong <cyd@gnu.org>
5875 * eval.c (Fuser_variable_p, user_variable_p_eh)
5876 (lisp_indirect_variable): Functions deleted.
5877 (Fdefvar): Caller changed.
5879 * callint.c (Finteractive, Fcall_interactively):
5880 * minibuf.c (Fread_variable): Callers changed.
5882 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5884 * xdisp.c (set_cursor_from_row): If the display string appears in
5885 the buffer at position that is closer to point than the position
5886 after the display string, display the cursor on the first glyph of
5887 the display string. Fixes cursor display when a 'display' text
5888 property immediately follows invisible text. (Bug#11094)
5890 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5892 composite.c: use 'double' consistently
5893 * composite.c (get_composition_id): Use 'double' consistently
5894 instead of converting 'float' to 'double' and vice versa; this is
5895 easier to understand and avoids a GCC warning.
5897 2012-04-09 Glenn Morris <rgm@gnu.org>
5899 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5900 preparation for dumping it with emacs. (Bug#4789)
5901 (leimdir): New variable.
5902 ($(leimdir)/leim-list.el): New rule.
5903 (emacs$(EXEEXT)): Depend on leim-list.el.

5906 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
5907 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
5909 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
5911 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5914 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
5916 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5917 Remove unused local variable.
5919 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5921 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5922 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5923 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5924 objects, as mark_maybe_pointer will catch them otherwise.
5925 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5926 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5928 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5930 Fix typo that broke non-Windows builds.
5931 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5933 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5935 Support building on MS-Windows with libxml2.
5937 * makefile.w32-in (OBJ2): Add xml.$(O).
5938 (GLOBAL_SOURCES): Add xml.c.
5939 ($(BLD)/xml.$(O)): New dependency list.
5941 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5942 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5943 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5944 [!WINDOWSNT]: New macros.
5945 (init_libxml2_functions, libxml2_loaded_p): New functions.
5946 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5947 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5948 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5949 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5951 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5952 Call init_libxml2_functions before calling libxml2 functions.
5953 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5955 * emacs.c: Don't include libxml/parser.h.
5956 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5957 xmlCleanupParser directly.
5959 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5961 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5963 * indent.c (Fvertical_motion): If there is a display string at
5964 point, use it.vpos to compute how many lines to backtrack after
5965 move_it_to point. (Bug#11133)
5967 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5969 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5970 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5971 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5972 macros related to unification of CJK characters. For the details,
5973 see the discussion following the message here:
5974 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5976 2012-04-04 Chong Yidong <cyd@gnu.org>
5978 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5980 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5982 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5983 instead of alloca. (Bug#11138)
5985 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5987 * w32menu.c (is_simple_dialog): Properly check lisp types.
5990 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5992 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5993 position we get to after a call to move_it_to fails the
5994 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5995 only if we wind up in a string from display property. (Bug#11063)
5997 * window.c (Fdelete_other_windows_internal): Invalidate the row
5998 and column information about mouse highlight, so that redisplay
5999 restores it after reallocating the glyph matrices. (Bug#7464)
6001 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
6002 string comes from a `display' text property, use the buffer
6003 position of that property as if we actually saw that position in
6005 (move_it_by_lines): Remove the assertion that
6006 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6007 violated when there's a before-string at the beginning of a line.
6010 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6012 * xdisp.c (append_space_for_newline): If the default face was
6013 remapped, use the remapped face for the appended newline.
6014 (extend_face_to_end_of_line): Use the remapped default face for
6015 extending the face to the end of the line.
6016 (display_line): Call extend_face_to_end_of_line when the default
6017 face was remapped. (Bug#11068)
6019 2012-03-29 Eli Zaretskii <eliz@gnu.org>
6021 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
6023 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
6025 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
6027 2012-03-27 Glenn Morris <rgm@gnu.org>
6029 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
6032 2012-03-26 Kenichi Handa <handa@m17n.org>
6034 * dispextern.h (struct glyph): Fix previous change. Change the
6035 bit length of glyphless.ch to 25 (Bug#11082).
6037 2012-03-26 Chong Yidong <cyd@gnu.org>
6039 * keyboard.c (Vselection_inhibit_update_commands): New variable.
6040 (command_loop_1): Use it; inhibit selection update for
6041 handle-select-window too (Bug#8996).
6043 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
6045 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
6047 2012-03-25 Kenichi Handa <handa@m17n.org>
6049 * dispextern.h (struct glyph): Change the bit length of
6050 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6052 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6054 * s/ms-w32.h (tzname): Include time.h before redirecting to
6055 _tzname. Fixes the MSVC build. (Bug#9960)
6057 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
6059 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6062 * xterm.c (XTread_socket): Only modify handling_signal if
6063 !SYNC_INPUT. (Bug#11080)
6065 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6067 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6068 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6069 when fetching a multibyte character consumes more bytes than
6070 CHAR_BYTES returns, due to unification of CJK characters in
6071 string_char. (Bug#11073)
6073 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6075 * process.c (wait_reading_process_output): Handle pty disconnect
6076 by refraining from sending oneself a SIGCHLD (bug#10933).
6078 2012-03-22 Chong Yidong <cyd@gnu.org>
6080 * dispextern.h (struct it): New member string_from_prefix_prop_p.
6082 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
6083 Mark string as coming from a prefix property.
6084 (handle_face_prop): Use default face for prefix strings (Bug#4281).
6085 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
6087 2012-03-21 Chong Yidong <cyd@gnu.org>
6089 * xfaces.c (Vface_remapping_alist): Doc fix.
6091 2012-03-20 Eli Zaretskii <eliz@gnu.org>
6093 * w32proc.c (Fw32_set_console_codepage)
6094 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
6097 2012-03-20 Chong Yidong <cyd@gnu.org>
6099 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
6100 to reflect default non-nil value of redisplay-dont-pause.
6102 2012-03-19 Kenichi Handa <handa@m17n.org>
6104 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
6105 it fit in a valid range (Bug#11003).
6107 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6109 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6110 that is not from display property, accept the row as a "cursor
6111 row" if one of the string's character has a non-nil `cursor'
6112 property. Fixes cursor positioning when there are newlines in
6113 overlay strings, e.g. in icomplete.el. (Bug#11035)
6115 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6117 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
6119 2012-03-12 Chong Yidong <cyd@gnu.org>
6121 * eval.c (inhibit_lisp_code): Rename from
6122 inhibit_window_configuration_change_hook; move from window.c.
6124 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6125 * window.c (run_window_configuration_change_hook)
6126 (syms_of_window): Callers changed.
6128 2012-03-11 Chong Yidong <cyd@gnu.org>
6130 * keymap.c (Fkey_description): Doc fix (Bug#9700).
6132 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
6134 2012-03-10 Chong Yidong <cyd@gnu.org>
6136 * frame.c (other_visible_frames): Don't assume the selected frame
6137 is visible (Bug#10955).
6139 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
6141 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6143 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6145 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6146 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6149 2012-03-03 Glenn Morris <rgm@gnu.org>
6151 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6153 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6155 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6156 position past the first glyph_row that ends at ZV. (Bug#10902)
6157 (redisplay_window, next_element_from_string): Fix typos in
6159 (redisplay_window): Pass to move_it_vertically the margin in
6160 pixels, not in screen lines.
6162 2012-03-02 Glenn Morris <rgm@gnu.org>
6164 * buffer.c (buffer-list-update-hook): Doc fix.
6166 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6168 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6169 push_it before setting up the iterator for the first overlay
6170 string, even if we have an empty string loaded.
6171 (next_overlay_string): If there's an empty string on the iterator
6172 stack, pop the stack. (Bug#10903)
6174 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6176 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6177 Suggested by Stefan Monnier in
6178 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6179 * alloc.c (widen_to_Lisp_Object): New static function.
6180 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6181 and widening them to Lisp_Objects. This would work even if
6182 USE_LSB_TAG is defined and wide integers are used, which might
6183 happen in a future version of Emacs.
6185 2012-02-25 Chong Yidong <cyd@gnu.org>
6187 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6190 * xselect.c (Fx_selection_exists_p): Doc fix.
6191 (x_clipboard_manager_save_all): Print an informative message
6192 before saving to clipboard manager.
6194 2012-02-24 Chong Yidong <cyd@gnu.org>
6196 * keyboard.c (process_special_events): Handle all X selection
6197 requests in kbd_buffer, not just the next one (Bug#8869).
6199 2012-02-23 Chong Yidong <cyd@gnu.org>
6201 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
6202 call when setting menu-bar-lines and tool-bar-lines parameters.
6203 (unwind_create_frame_1): New helper function.
6205 * window.c (inhibit_window_configuration_change_hook): New var.
6206 (run_window_configuration_change_hook): Obey it.
6207 (syms_of_window): Initialize it.
6209 2012-02-22 Chong Yidong <cyd@gnu.org>
6211 * xterm.c (x_draw_image_relief): Add missing type check for
6212 Vtool_bar_button_margin (Bug#10743).
6214 2012-02-21 Chong Yidong <cyd@gnu.org>
6216 * fileio.c (Vfile_name_handler_alist): Doc fix.
6218 * buffer.c (Fget_file_buffer): Protect against invalid file
6219 handler return value.
6221 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
6223 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
6224 when computing $valmask.
6226 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6227 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6228 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6229 It's useless in that case, and it can cause problems on hosts
6230 that allocate halves of EMACS_INT values separately.
6231 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6232 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6233 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6234 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6235 it avoids undefined behavior on hosts where shifting right by more
6236 than the word width has undefined behavior.
6238 2012-02-19 Chong Yidong <cyd@gnu.org>
6240 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
6241 (Funhandled_file_name_directory, Ffile_name_as_directory)
6242 (Fdirectory_file_name, Fexpand_file_name)

7024 to 4 (xorl, subq, cmpq, setbe).
7025 * alloc.c (pure): Always extern now, since that's the

7038 behave as if the cursor position were at the window margin.
7040 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7041 and the cursor position is out of bounds, behave as if the cursor
7042 position were at the window margin. (Bug#10075)

7072 * dispnew.c (verify_row_hash): Call row_hash for computing the
7073 hash code of a row, instead of duplicating code from xdisp.c.
7075 * dispextern.h (row_hash): Add prototype.
7077 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
7079 * frame.c (delete_frame): Don't delete the terminal when the last

7234 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
7235 This is also needed for porting to any host where GC_MARK_STACK is
7236 not GC_MAKE_GCPROS_NOOPS.
7237 (which_symbols): Use it.
7239 2011-11-07 Kenichi Handa <handa@m17n.org>
7241 * coding.c (coding_set_destination): Check coding->src_pos only
7242 when coding->src_object is a buffer (bug#9910).

7252 * xmenu.c (cleanup_widget_value_tree): New function.
7253 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
7254 calling free_menubar_widget_value_tree directly (Bug#9830).
7256 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
7258 Fix some portability problems with 'inline'.
7259 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
7260 (window_box_width, window_box_left, window_box_left_offset)
7261 (window_box_right, window_box_right_offset): Declare extern.
7262 Otherwise, these inline functions do not conform to C99 and
7263 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7264 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7265 * intervals.c (adjust_intervals_for_insertion)
7266 (adjust_intervals_for_deletion): Now extern, because otherwise the
7267 extern inline functions 'offset_intervals' couldn't refer to it.
7268 (static_offset_intervals): Remove.
7269 (offset_intervals): Rewrite using the old contents of
7270 static_offset_intervals. The old version didn't conform to C99
7271 because an extern inline function contained a reference to an
7272 identifier with static linkage.
7274 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
7276 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

7294 (Fwindow_vscroll): Doc fix.
7295 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
7296 argument, since it makes no sense to pass a live window and for
7297 consistency with window-child.

7325 (unwind_create_frame): New function (Bug#9943).
7326 (Fx_create_frame): Restructure code to be more similar to the one in
7327 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
7328 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
7329 Move terminal->reference_count++ just before making the frame official

7408 Rename cover_string to disp_string.
7410 2011-11-01 Martin Rudalics <rudalics@gmx.at>

7443 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
7444 so that this new function doesn't get optimized away by a
7445 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
7447 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
7449 * frame.h (MOUSE_HL_INFO): Remove excess parens.

7505 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
7507 (w32font_open_internal, compute_metrics):
7508 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7509 instead of calling the "wide" APIs directly.
7511 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

7524 * process.c (make_process): Set gnutls_state to NULL.
7526 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
7527 non-NULL, regardless of GNUTLS_INITSTAGE.
7528 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7529 an error. Set process slots as soon as we allocate them.

7576 (bidi_resolve_weak): Don't enter the expensive loop if the current
7577 position is before next_en_pos. Record the bidi type of the first
7578 non-ET, non-BN character we find, in addition to its position.
7579 (bidi_level_of_next_char): Invalidate next_en_type when
7580 next_en_pos is over-stepped.
7582 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7584 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7585 * editfns.c: Rewrite current-time-zone so that it invokes
7586 the equivalent of (format-time-string "%Z") to get the time zone name.
7587 This fixes a bug when the time zone name contains characters that
7588 need converting from the system time locale to Emacs internal format.
7589 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7590 that patch fixed format-time-string to do the conversion, but
7591 I forgot to fix current-time-zone.
7592 (format_time_string): New function, containing most of
7593 what Fformat_time_string used to contain.
7594 (Fformat_time_string): Rewrite in terms of format_time_string.
7595 This doesn't change this function's behavior.
7596 (current-time-zone): Rewrite to use format_time_string.
7597 This fixes the bug reported by Michael Schierl in
7598 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7599 Jason Rumney's 2007-06-07 change worked around this bug, but
7601 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7603 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7605 * xdisp.c (start_display): If the character at POS is displayed
7606 via a display vector, reset IT->current.dpvec_index to zero.
7607 (try_window_reusing_current_matrix): If a line ends in a display
7608 vector or the next line starts in a display vector, continue
7609 redrawing the window even though the character position of
7610 start_row was reached.
7613 2011-10-18 Chong Yidong <cyd@gnu.org>
7615 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7616 with nobreak-char-display too.
7618 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7620 Fix part 3 of bug#9771.
7621 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7622 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7623 non-neutral characters if the current character is a paragraph
7624 separator (a.k.a. Newline). This avoids running the same
7625 expensive loop twice, once when we consume the preceding newline
7626 and the other time when the line actually needs to be displayed.
7627 Avoid the loop when we see neutrals on the base embedding level
7628 following a character whose directionality is the same as the
7629 paragraph's. This avoids running the expensive loop when a line
7630 ends in a long sequence of neutrals, like control characters.
7631 Add assertion against STRONG_AL type. Slightly rearrange code
7632 that determines the type of a neutral given the first non-neutral
7634 (bidi_level_of_next_char): Set next_en_pos to zero when
7635 invalidating its info.
7637 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7639 * xdisp.c (push_display_prop): Determine whether to record string
7640 or buffer position by IT->string, not by IT->method. Allow
7641 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7642 (move_it_vertically_backward): Don't look for character position
7643 immediately after the newline when in a continuation line.
7646 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7648 * window.c (coordinates_in_window): Rewrite and delabelize
7649 vertical border check. (Bug#5357) (Bug#9618)
7651 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7653 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7654 errors in XSetWindowBorder (bug#9310).

7658 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7659 avoid crash when xmalloc overrun checking is enabled.
7661 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7663 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7664 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7665 cursor motion with <left> and <right> arrow keys.
7667 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7668 some callers set that themselves.
7670 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7672 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7673 display string and the previous row comes from the same string and
7674 is empty. (Bug#9739) (Bug#9738)
7676 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7678 * doc.c (get_doc_string): Encode file name (bug#9735).
7680 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7682 * bidi.c (bidi_level_of_next_char):
7683 * xdisp.c (get_visually_first_element): Remove old incorrect
7684 comments regarding the Unicode Line Separator character.
7686 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.

7696 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7697 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7699 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7700 Some packages use them to denote characters with modifiers.
7702 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7704 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7705 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7706 matching a pp-number. Rename parameter var to var1.
7708 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7710 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7712 2011-10-08 Glenn Morris <rgm@gnu.org>
7714 * callint.c (Fcall_interactively): Give a more explicit error for the
7715 'c' case with a non-character input. (Bug#8479)
7717 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7719 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7721 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7722 lines that are hscrolled on the left.
7724 * dispnew.c (buffer_posn_from_coords): Account for a possible
7725 presence of header-line. (Bug#4426)
7727 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7729 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7730 Don't advertise functionality which we discourage or doesn't work.
7732 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7734 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7735 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7736 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7737 this makes Emacs dump core during garbage collection on rare
7738 occasions. sizeof is obviously inferior to offsetof here, so
7739 stick with offsetof.
7740 (GC_POINTER_ALIGNMENT): New macro.
7741 (mark_memory): Omit 3rd (offset) arg; caller changed.
7742 Don't assume EMACS_INT alignment is the same as pointer alignment.
7744 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7746 * keyboard.c (read_key_sequence_remapped): New var.
7747 (read_key_sequence): Compute remapping in the right buffer.
7748 (command_loop_1): Use read_key_sequence's remapping directly.
7750 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7752 * dired.c (file_name_completion): Don't expand file name.
7753 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7754 before checking file name handler.
7756 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7757 they've been requested explicitly (bug#9591).
7759 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7761 * keymap.c (Fsingle_key_description): Use make_specified_string
7762 instead of build_string to build string from push_key_description.
7765 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7767 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7768 This fixes a Y2038 bug on 64-bit hosts.
7769 * buffer.c (reset_buffer):
7770 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7771 (Fclear_buffer_auto_save_failure):
7772 Use 0, not -1, to represent an unset failure time, since time_t
7773 might not be signed.
7775 Remove dependency on glibc malloc internals.
7776 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7777 Move back here from lisp.h, but with their new implementations.
7778 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7779 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7780 * charset.c (charset_table_init): New static var.
7781 (syms_of_charset): Use it instead of xmalloc. This removes a
7782 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7783 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7784 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7785 Move back to alloc.c.
7786 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7787 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7789 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7791 * nsterm.m (windowDidResize): Call x_set_window_size only when
7792 ns_in_resize is true. Otherwise set pixelwidth/height and
7793 call change_frame_size (Bug#9628).
7795 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7797 Port --enable-checking=all to Fedora 14 x86-64.
7798 * charset.c (syms_of_charset): Also account for glibc malloc's
7799 internal overhead when calculating the initial malloc maximum.
7801 Port --enable-checking=all to Fedora 14 x86.
7802 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7804 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7805 (overrun_check_realloc, overrun_check_free):
7806 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7807 That way, xmalloc returns a properly-aligned pointer even if
7808 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7809 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7810 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7811 into account when calculating the initial malloc maximum.
7812 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7813 Move here from alloc.c, so that charset.c can use it too.
7814 Properly align; the old code wasn't right for common 32-bit hosts
7815 when configured with --enable-checking=all.
7816 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7817 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7819 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7821 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7824 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7826 * xdisp.c (compute_display_string_end): If there's no display
7827 string at CHARPOS, return -1.
7829 * bidi.c (bidi_fetch_char): When compute_display_string_end
7830 returns a negative value, treat the character as a normal
7831 character not covered by a display string. (Bug#9624)
7833 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7835 * lread.c (Fread_from_string): Fix typo in docstring.
7837 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7839 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7840 newline, reseat the iterator instead of bidi-iterating there one
7841 character at a time. (Bug#9610)
7842 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7843 TO_CHARPOS if the bidi iterator is at base embedding level.
7845 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7847 * lread.c (readevalloop): Use correct code for NBSP.
7848 (read1): Likewise. (Bug#9608)
7850 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7852 * dbusbind.c (Fdbus_register_signal): When service is not
7853 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7855 2011-09-25 Glenn Morris <rgm@gnu.org>
7857 * buffer.c (truncate-lines): Doc fix.
7859 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7861 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7862 (Fset_window_next_buffers): Doc fix.
7864 2011-09-24 Glenn Morris <rgm@gnu.org>
7866 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7868 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7870 Fix minor problems found by static checking.
7871 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7872 * indent.c (Fvertical_motion): Fix == vs = typo.
7874 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7876 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7877 Default value is now t. Doc fix.
7879 * indent.c (Fvertical_motion): Compute and apply the overshoot
7880 logic when moving up, not only when moving down. Fix the
7881 confusing name and values of the it_overshoot_expected variable;
7882 logic changes accordingly. (Bug#9254) (Bug#9549)
7884 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7885 CHARPOS is covered by a display string which includes newlines.
7886 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7887 is covered by a display string with embedded newlines.
7889 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7891 * dbusbind.c (Fdbus_register_signal): Add match rule to
7892 Vdbus_registered_objects_table. (Bug#9581)
7893 (Fdbus_register_method, Vdbus_registered_objects_table):
7896 2011-09-24 Jim Meyering <meyering@redhat.com>
7898 do not ignore write error for any output size
7899 The previous change was incomplete.
7900 While it makes emacs --batch detect the vast majority of stdout
7901 write failures, errors were still ignored whenever the output size is
7902 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7903 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7904 && echo FAIL: ignored write error
7905 FAIL: ignored write error
7906 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7907 && echo FAIL: ignored write error
7908 FAIL: ignored write error
7909 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7911 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7913 * emacs.c (Fkill_emacs): In noninteractive mode exit
7914 non-successfully if a write error occurred on stdout. (Bug#9574)
7916 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7918 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7921 * dispextern.h (struct it): Update the comment documenting what
7924 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7926 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7927 a display string, extend search for cursor position to end of row.
7928 (find_row_edges): If the row ends in a newline from a display
7929 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7930 Handle the case of a display string with multiple newlines.
7931 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7932 non-empty line. Fixes confusing cursor motion with arrow keys at
7933 the beginning of a line that starts with whitespace.
7935 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7937 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7940 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7942 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7945 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7947 * xdisp.c (display_line): Record maximum and minimum buffer
7948 positions even if no glyphs were produced (e.g., by a zero-width
7949 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7950 buffer positions that will be removed from the glyph row because
7952 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7953 column is beyond frame width: don't subtract 1 "pixel" when
7954 computing width of the stretch.
7955 (reseat_at_next_visible_line_start): Undo the change made on
7956 2011-09-17 that saved paragraph information and restored it after
7957 the call to `reseat'. (Bug#9545)
7959 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7961 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7962 and turn window cursor on if cleared (Bug#9415).
7964 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7966 * search.c (boyer_moore): Take unibyte characters from pattern
7967 literally. (Bug#9458)
7969 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7971 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7973 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7975 Fix minor problem found by static checking.
7976 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7977 initialized, to pacify gcc -Wuninitialized.
7979 * fileio.c: Report proper errno when syscall falls.
7980 (Finsert_file_contents): Save and restore errno,
7981 so that report_file_error outputs the correct diagnostic.
7982 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7984 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7986 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7988 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7990 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7991 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7993 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7995 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7996 about the current paragraph and restore it after the call to reseat.
7998 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7999 (bidi_find_paragraph_start): Search back for paragraph beginning
8000 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
8001 (bidi_move_to_visually_next): Only trigger paragraph-related
8002 computations when the last character is a newline or at EOB, not
8003 just any NEUTRAL_B. (Bug#9470)
8005 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
8006 truncated lines if point is covered by a display string. (Bug#9524)
8008 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
8010 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8011 (cons_to_x_long): New function.
8012 (lisp_data_to_selection_data): Use it. Correct the test for
8013 short-versus-long data; it was negated. Break out of vector
8014 loop, for efficiency, when a long datum is discovered.
8016 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8018 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8020 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8022 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
8023 GCC PR/17406) by declaring this function with external scope.
8025 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8027 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
8028 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
8030 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
8032 * editfns.c (Fformat): Correctly handle text properties on "%%".
8034 2011-09-15 Eli Zaretskii <eliz@gnu.org>
8036 * xterm.c (x_draw_composite_glyph_string_foreground):
8037 * w32term.c (x_draw_composite_glyph_string_foreground):
8038 * term.c (encode_terminal_code):
8039 * composite.c (composition_update_it, get_composition_id):
8040 * xdisp.c (get_next_display_element)
8041 (fill_composite_glyph_string): Add comments about special meaning
8042 of TAB characters in a composition.
8044 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8046 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8047 This occurs when processing a multibyte format.
8048 Problem reported by Wolfgang Jenker.
8050 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8052 * xdisp.c (try_cursor_movement): Only check for exact match if
8053 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8055 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8057 Remove unused external symbols.
8058 * dispextern.h (calc_pixel_width_or_height): Remove decl.
8059 * xdisp.c (calc_pixel_width_or_height): Now static.
8060 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
8061 * indent.c (check_display_width):
8062 * w32term.c: Fix comment to match code.
8063 * xterm.c, xterm.h (x_catching_errors): Remove.
8065 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8067 * xselect.c: Use signed conversions more consistently (Bug#9498).
8068 (selection_data_to_lisp_data): Assume incoming selection data are
8069 signed integers, not unsigned. This is to be consistent with
8070 outgoing selection data, which was modified to use signed integers
8071 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8072 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8073 expects long, not unsigned long.
8075 2011-09-14 Eli Zaretskii <eliz@gnu.org>
8077 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
8078 computation of loop end. Reported by Johan Bockgård
8081 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
8083 * frame.c (Fother_visible_frames_p): Function deleted.
8085 2011-09-12 Eli Zaretskii <eliz@gnu.org>
8087 * indent.c (compute_motion): Process display vector front to back
8088 rather than the other way around. (Bug#2496)
8090 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
8092 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
8094 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
8096 * minibuf.c (Fread_from_minibuffer): Doc fix.
8098 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8100 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8101 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8103 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8105 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8106 value for non-existent files.
8108 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8110 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8111 set its "size" to -1. This will set the modtime_size field of
8112 the corresponding buffer to -1, which is what
8113 verify-visited-file-modtime expects for files that do not exist.
8116 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8118 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8120 * lisp.h: ... from here. push_key_description is no longer
8121 defined in keyboard.c, so its declaration should not be in
8122 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8123 logically belongs with push_key_description.
8125 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8127 * buffer.h: Include <sys/types.h> instead of <time.h>.
8128 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8129 Problem reported by Herbert J. Skuhra.
8131 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8133 * xml.c (parse_region): Make the parsing work for
8134 non-comment-starting XML files again (bug#9144).
8136 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8138 * image.c (gif_load): Fix calculation of bottom and right corner.
8141 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8143 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8144 redisplay in small windows.
8146 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8148 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8150 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8152 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8153 Operate on live windows only.
8155 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8157 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8159 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8161 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8162 only under bidi iteration.
8164 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8166 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8168 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8170 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8171 Without this fix, the command to link temacs failed due to an
8172 undefined symbol __builtin_isnan. This is because
8173 /usr/include/iso/math_c99.h #defines isnan(x) to
8174 __builtin_isnan(x), but the bundled gcc, which identifies itself
8175 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8177 * floatfns.c (isnan): #undef, and then #define to a clone of
8179 (Fisnan): Always define, since it's always available now.
8180 (syms_of_floatfns): Always define isnan at the Lisp level.
8182 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8184 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8186 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8188 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8189 The previous code assumed that file offsets (off_t values) fit in
8190 EMACS_INT variables, which is not true on typical 32-bit hosts.
8191 The code messed up by falsely reporting buffer overflow in cases
8192 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8193 when "big" contains more than 2**29 bytes, even though this
8194 inserts just one byte and does not overflow the buffer.
8195 (Finsert_file_contents): Store file offsets as off_t
8196 values, not as EMACS_INT values. Check for overflow when
8197 converting between EMACS_INT and off_t. When checking for
8198 buffer overflow or for overlap, take the offsets into account.
8199 Don't use EMACS_INT for small values where int suffices.
8200 When checking for overlap, fix a typo: ZV was used where
8201 ZV_BYTE was intended.
8202 (Fwrite_region): Don't assume off_t fits into 'long'.
8203 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8205 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8207 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8209 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8211 sprintf-related integer and memory overflow issues (Bug#9412).
8213 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8214 (esprintf, exprintf, evxprintf): New functions.
8215 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8216 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8217 (modify_event_symbol): Do not assume that the length of
8218 name_alist_or_stem is safe to alloca and fits in int.
8219 (Fexecute_extended_command): Likewise for function name and binding.
8220 (Frecursion_depth): Wrap around reliably on integer overflow.
8221 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8222 since some callers pass EMACS_INT values.
8223 (Fsingle_key_description): Don't crash if symbol name contains more
8224 than MAX_ALLOCA bytes.
8225 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8226 (get_minibuffer): Arg is now EMACS_INT, not int.
8227 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8228 (esprintf, exprintf, evxprintf): New decls.
8229 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8231 * dbusbind.c (signature_cat): New function.
8232 (xd_signature, Fdbus_register_signal):
8233 Do not overrun buffer; instead, report string overflow.
8235 * dispnew.c (add_window_display_history): Don't overrun buffer.
8236 Truncate instead; this is OK since it's just a log.
8238 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8239 even if the time zone offset is outlandishly large.
8240 Don't mishandle offset == INT_MIN.
8242 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8243 when creating daemon; the previous buffer-overflow check was incorrect.
8245 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8246 which has the guts of the old verror function.
8248 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8249 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8251 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8252 (font_unparse_xlfd): Don't blindly alloca long strings.
8253 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8254 fits in int, when using sprintf. Use single snprintf to count
8255 length of string rather than counting it via multiple sprintfs;
8256 that's simpler and more reliable.
8257 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8258 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8259 sprintf, in case result does not fit in int.
8261 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8262 (fontset_from_font): Print it.
8264 * frame.c (tty_frame_count): Now printmax_t, not int.
8265 (make_terminal_frame, set_term_frame_name): Print it.
8266 (x_report_frame_params): In X, window IDs are unsigned long,
8267 not signed long, so print them as unsigned.
8268 (validate_x_resource_name): Check for implausibly long names,
8269 and don't assume name length fits in 'int'.
8270 (x_get_resource_string): Don't blindly alloca invocation name;
8271 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8274 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8275 (xg_check_special_colors, xg_set_geometry):
8276 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8278 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8279 Use esprintf, not sprintf, in case result does not fit in int.
8281 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8282 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8283 it as a large positive number.
8284 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8285 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8287 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8288 in case result does not fit in int.
8290 * print.c (float_to_string): Detect width overflow more reliably.
8291 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8292 buffer overrun. Don't assume list length fits in 'int'. Treat
8293 print length of 0 as 0, not as infinity; to be consistent with other
8294 uses of print length in this function. Don't overflow print length
8295 index. Don't assume hash table size fits in 'long', or that
8296 vectorlike size fits in 'unsigned long'.
8298 * process.c (make_process): Use printmax_t, not int, to format
8299 process-name gensyms.
8301 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8303 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8304 to avoid potential buffer overrun.
8306 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8307 if X resource line is longer than 512 bytes.
8309 * xfns.c (x_window): Make sprintf buffer a bit bigger
8310 to avoid potential buffer overrun.
8312 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8314 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8316 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8318 Integer overflow fixes for scrolling, etc.
8319 Without these, Emacs silently mishandles large integers sometimes.
8320 For example, "C-u 4294967297 M-x recenter" was treated as if
8321 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8323 * xdisp.c (try_window_id): Check Emacs fixnum range before
8324 converting to 'int'.
8326 * window.c (window_scroll_line_based, Frecenter):
8327 Check that an Emacs fixnum is in range before assigning it to 'int'.
8328 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8329 values converted from Emacs fixnums.
8330 (Frecenter): Don't wrap around a line count if it is out of 'int'
8331 range; instead, treat it as an extreme value.
8332 (Fset_window_configuration, compare_window_configurations):
8333 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8335 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8336 that can exceed INT_MAX. Check that EMACS_INT value is in range
8337 before assigning it to the (possibly-narrower) index.
8338 (match_limit): Don't assume that a fixnum can fit in 'int'.
8340 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8343 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8344 (Fvertical_motion): Don't wrap around LINES values that don't fit
8345 in 'int'. Instead, treat them as extreme values. This is good
8346 enough for windows, which can't have more than INT_MAX lines anyway.
8348 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8350 * Require libxml/parser.h to avoid compilation warning.
8352 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8354 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8355 since this reportedly can destroy thread storage.
8357 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8359 * syntax.c (find_defun_start): Update all cache variables if
8360 exiting early (Bug#9401).
8362 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8364 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8366 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8367 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8368 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8370 * term.c (tty_append_glyph): New function.
8371 (produce_stretch_glyph): Static function and its prototype deleted.
8373 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8376 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8378 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8379 when checking :margin (Bug#9390).
8380 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8381 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8382 so that the name doesn't mislead. All uses changed.
8384 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8386 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8389 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8391 * xdisp.c (move_it_to): Don't bail out early when reaching
8392 position beyond to_charpos, if we are scanning backwards.
8393 (move_it_vertically_backward): When DY == 0, make sure we get to
8394 the first character in the line after the newline.
8396 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8398 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8399 (ccl_driver): Do not generate an out-of-range pointer.
8400 (Fccl_execute_on_string): Remove unnecessary check for
8401 integer overflow, noted by Stefan Monnier in
8402 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8403 Remove a FIXME that didn't need fixing.
8404 Simplify the newly-introduced buffer reallocation code.
8406 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8408 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8410 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8412 Integer and memory overflow issues (Bug#9196).
8414 * doc.c (get_doc_string): Rework so that
8415 get_doc_string_buffer_size is the actual buffer size, rather than
8416 being 1 less than the actual buffer size; this makes xpalloc more
8419 * image.c (x_allocate_bitmap_record, cache_image):
8420 * xselect.c (Fx_register_dnd_atom):
8421 Simplify previous changes by using xpalloc.
8423 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8424 since either will do and ptrdiff_t is convenient with xpalloc.
8426 * charset.c (charset_table_size)
8427 (struct charset_sort_data.priority): Now ptrdiff_t.
8428 (charset_compare): Don't overflow if priorities differ greatly.
8429 (Fsort_charsets): Don't assume list length fits in int.
8430 Check for size-calculation overflow when allocating sort data.
8431 (syms_of_charset): Allocate an initial charset table that is
8432 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8434 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8436 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8437 The actual value is always <= INT_MAX, and leaving it unsigned made
8438 overflow checking harder.
8440 * dispextern.h (struct glyph_matrix.rows_allocated)
8441 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8442 with xpalloc. The values are still always <= INT_MAX.
8444 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8446 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8447 (SAFE_NALLOCA): New macro.
8449 * region-cache.c (struct boundary.pos, find_cache_boundary)
8450 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8451 (set_cache_region, invalidate_region_cache)
8452 (revalidate_region_cache, know_region_cache, region_cache_forward)
8453 (region_cache_backward, pp_cache):
8454 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8455 so that ptrdiff_t * can be passed to xpalloc.
8456 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8457 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8458 (pp_cache): Don't assume cache_len fits in int.
8459 * region-cache.h: Adjust extern decls to match.
8461 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8462 EMACS_INT, since either will do, for xpalloc.
8464 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8465 (xnmalloc, xnrealloc, xpalloc): New functions.
8467 * bidi.c (bidi_shelve_header_size): New constant.
8468 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8469 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8471 * bidi.c (bidi_cache_shrink):
8472 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8474 Don't update size of array until after memory allocation succeeds,
8475 because xmalloc/xrealloc may not return.
8476 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8477 now that we have proper integer overflow checking.
8478 (record_overlay_string, overlay_strings): Catch overflows when
8479 calculating size of overlay_str_buf.
8481 * callproc.c (Fcall_process): Check for size overflow when
8482 calculating size of args2.
8483 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8484 Normally we prefer signed values, but sticking with ptrdiff_t would
8485 require adding more-complicated checks.
8487 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8488 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8489 Redo buffer-overflow calculations to avoid integer overflow.
8490 Add a FIXME comment where memory seems to be over-allocated.
8492 * character.c (Fstring): Check for size-calculation overflow.
8494 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8495 unnecessary integer overflow. Check for size overflow.
8496 (encode_coding_object): Don't update size until xmalloc succeeds.
8498 * composite.c (get_composition_id): Check for overflow in glyph
8499 length calculations.
8501 Integer and memory overflow fixes for display code.
8502 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8503 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8504 (scrolling_window): Check for overflow in size calculations.
8505 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8506 Don't assume glyph table len fits in int.
8507 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8508 (row_table_size): Now ptrdiff_t, not int.
8509 (scrolling_window): Avoid overflow in size calculations.
8510 Don't update size until allocation succeeds.
8511 * fns.c (concat): Check for overflow in size calculations.
8512 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8513 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8514 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8516 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8517 (get_doc_string): Check for size calculation overflow.
8518 Don't update size until allocation succeeds.
8519 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8520 EMACS_INT, where ptrdiff_t will do.
8521 (Fsubstitute_command_keys): Check for string overflow.
8523 * editfns.c (set_time_zone_rule): Don't assume environment length
8525 (message_length): Now ptrdiff_t, not int.
8526 (Fmessage_box): Don't update size until allocation succeeds.
8527 Don't assume message length fits in int.
8528 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8530 * emacs.c (main): Do not reallocate argv, since there is a null at
8531 the end that can be overwritten, and this way there's no need to
8532 worry about size-calculation overflow.
8533 (sort_args): Check for size-calculation overflow.
8535 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8537 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8539 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8540 (x_set_scroll_bar_width, x_figure_window_size):
8541 Check for integer overflow.
8542 (x_set_alpha): Do not assume XINT fits in int.
8544 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8545 This is for the members text_lines, text_cols, total_lines, total_cols,
8546 where the system imposes an 'int' limit.
8548 * fringe.c (Fdefine_fringe_bitmap):
8549 Don't update size until alloc works.
8551 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8552 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8554 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8555 Check for size-calculation overflow.
8556 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8557 do, as we prefer signed integers.
8558 (id_to_widget.max_size, id_to_widget.used)
8559 (xg_store_widget_in_map, xg_remove_widget_from_map)
8560 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8561 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8562 Use and return ptrdiff_t, not int.
8563 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8564 * gtkutil.h: Change prototypes to match the above.
8566 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8567 are duplicate now that they've been promoted to lisp.h.
8568 (x_allocate_bitmap_record, x_alloc_image_color)
8569 (make_image_cache, cache_image, xpm_load):
8570 Don't update size until alloc is done.
8571 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8573 Check for size calculation overflow.
8574 (ct_colors_allocated_max): New constant.
8575 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

8580 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8581 Use ptrdiff_t, not int, to count maps.
8582 (read_char_minibuf_menu_prompt): Check for overflow in size
8583 calculations. Don't update size until allocation succeeds.
8584 Redo calculations to avoid overflow.

8595 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8597 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8598 Now ptrdiff_t, not int.
8599 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8600 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
8602 * process.c (Fnetwork_interface_list): Check for overflow
8603 in size calculation.
8605 * region-cache.c (move_cache_gap): Check for size calculation overflow.

8608 overflow. Don't bother calling xmalloc when xrealloc will do.
8610 * search.c (Freplace_match): Check for size calculation overflow.
8611 (Fset_match_data): Don't assume list lengths fit in 'int'.
8613 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8614 for command line length. Do not attempt to address one before the
8615 beginning of an array, as that's not portable.

8618 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8620 (encode_terminal_code, calculate_costs): Check for size
8621 calculation overflow.
8622 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
8623 table lengths and related sizes. Don't update size until alloc
8624 done. Redo calculations to avoid overflow.

8627 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
8628 subtracting pointers.

8633 Don't update size until alloc done.
8634 Redo size calculations to avoid overflow.

8644 (Finternal_make_lisp_face, cache_face):
8645 Check for size calculation overflow.
8646 (cache_face): Treat size calculation overflows as if they were
8647 memory exhaustion (the usual treatment), rather than aborting.
8649 * xfns.c (x_encode_text, x_set_name_internal)
8650 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8651 sizes, since they can exceed INT_MAX in size. Check for size
8652 calculation overflow.
8654 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8655 (xg_select): Check for size calculation overflow.
8656 Don't update size until alloc done.
8658 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8659 as sprintf is limited to int lengths.
8661 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8662 (X_LONG_MIN): New macros.
8663 Use them to make the following changes clearer.
8664 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8665 This change doesn't affect the value now, but it may help remind
8666 future maintainers not to raise the value too much later.
8667 (SELECTION_QUANTUM): Remove, replacing with ...
8668 (selection_quantum): ... new function, which avoids overflow.
8670 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8671 assumption that selection length fits in 'int'.
8672 (x_reply_selection_request, x_handle_selection_request)
8673 (x_get_window_property, receive_incremental_selection)
8674 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8675 (lisp_data_to_selection_data, clean_local_selection_data):
8676 Use ptrdiff_t, not int, to record length of selection.

8678 (receive_incremental_selection, x_property_data_to_lisp):
8679 Redo calculations to avoid overflow.
8680 (x_reply_selection_request): When sending hint, ceiling it at
8681 X_LONG_MAX rather than relying on wraparound overflow to send
8683 (x_get_window_property, receive_incremental_selection)
8684 (lisp_data_to_selection_data, x_property_data_to_lisp):
8685 Check for size-calculation overflow.
8686 (x_get_window_property, receive_incremental_selection)

8688 Don't store size until memory allocation succeeds.
8689 (x_get_window_property): Plug memory leak on memory exhaustion.
8690 Don't double-block input; malloc is safe here. Don't assume 2**34
8691 - 4 fits in unsigned long. Add an xassert to check
8692 XGetWindowProperty overflow. Be more careful about overflow
8693 calculations, and distinguish size from memory overflow better.
8694 (receive_incremental_selection): When tracing, don't assume
8695 unsigned int is less than INT_MAX.
8696 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8697 harmful) conversions of unsigned short to int.
8698 (lisp_data_to_selection_data): Don't assume that integers
8699 in the range -65535 through -1 fit in an X unsigned short.
8700 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8701 result parameters unless successful. Rely on cons_to_unsigned
8702 to report problems with elements; the old code wasn't right anyway.
8703 (x_check_property_data): Check for int overflow; we cannot use
8704 a wider type due to X limits.
8705 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8707 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
8709 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
8710 (x_term_init): Check for size calculation overflow.
8711 (x_color_cells): Don't store size until memory allocation succeeds.
8712 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
8713 Don't assume alloca size is less than MAX_ALLOCA.

8736 * image.c (xpm_get_color_table_h):
8737 * lisp.h (hash_lookup, hash_put):
8738 * minibuf.c (Ftest_completion):
8739 Use ptrdiff_t for hash table indexes, not int (which is too
8740 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8741 32-bit --with-wide-int hosts).
8743 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8744 Add a FIXME comment about memory leaks.
8745 (syms_of_charset): Don't assume xmalloc returns.
8747 Don't assume that stated character widths fit in int.
8748 * character.c (Fchar_width, c_string_width, lisp_string_width):
8749 * character.h (CHAR_WIDTH):
8750 * indent.c (MULTIBYTE_BYTES_WIDTH):
8751 Use sanitize_char_width to avoid undefined and/or bad behavior
8752 with outlandish widths.
8753 * character.h (sanitize_tab_width): Rename from sanitize_width,
8754 now that we have two such functions. All uses changed.
8755 (sanitize_char_width): New inline function.
8757 Don't assume that tab-width fits in int.
8758 * character.h (sanitize_width): New inline function.
8759 (SANE_TAB_WIDTH): New macro.
8760 (ASCII_CHAR_WIDTH): Use it.
8761 * indent.c (sane_tab_width): Remove. All uses replaced by
8762 SANE_TAB_WIDTH (current_buffer).
8763 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
8765 * fileio.c: Integer overflow issues with file modes.
8766 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.

8772 * xterm.c: Don't go over XClientMessageEvent limit.
8773 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8774 (x_send_scroll_bar_event): Likewise. Check that the size does not
8775 exceed limits imposed by XClientMessageEvent, as well as the usual
8776 ptrdiff_t and size_t limits.
8778 * keyboard.c: Overflow, signedness and related fixes.
8779 (make_lispy_movement): Use same integer type in forward decl
8780 that is used in the definition.
8781 (read_key_sequence, keyremap_step):
8782 Change bufsize argument back to int, undoing my 2011-03-30 change.
8783 We prefer signed types, and int is wide enough here.
8784 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8785 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8786 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8787 length, not size_t. Use ptrdiff_t for index, not int.
8788 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8789 possibility of integer overflow.
8791 Overflow, signedness and related fixes for images.
8793 * dispextern.h (struct it.stack[0].u.image.image_id)
8794 (struct_it.image_id, struct image.id, struct image_cache.size)

8800 * nsmenu.m (update_frame_tool_bar):
8801 * xdisp.c (calc_pixel_width_or_height):
8802 * xfns.c (image_cache_refcount):
8803 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8804 on typical 64-bit hosts.
8806 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8807 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8812 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8813 (lookup_image): Remove unnecessary tests.
8814 (xbm_image_p): Locals are now of int, not EMACS_INT,
8815 since parse_image_check makes sure they fit into int.
8816 (png_load, gif_load, svg_load_image):
8817 Prefer int to unsigned where either will do.
8818 (tiff_handler): New function, combining the cores of the
8819 old tiff_error_handler and tiff_warning_handler.
8820 This function is rewritten to use vsnprintf and thereby avoid
8821 stack buffer overflows. It uses only the features of vsnprintf
8822 that are common to both POSIX and native Microsoft.
8823 (tiff_error_handler, tiff_warning_handler): Use it.
8824 (tiff_load, gif_load, imagemagick_load_image):
8825 Don't assume :index value fits in 'int'.
8826 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8827 (imagemagick_load_image): Check that crop parameters fit into
8828 the integer types that MagickCropImage accepts. Don't assume
8829 Vimagemagick_render_type has a nonnegative value. Don't assume
8830 size_t fits in 'long'.
8831 (gs_load): Use printmax_t to print the widest integers possible.
8832 Check for integer overflow when computing image height and width.
8834 2011-08-26 Eli Zaretskii <eliz@gnu.org>
8836 * xdisp.c (redisplay_window): Don't force window start if point
8837 will be invisible in the resulting window. (Bug#9324)
8839 2011-08-25 Eli Zaretskii <eliz@gnu.org>
8841 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8842 the display spec is of the form `(space ...)'.
8843 (handle_display_spec): Return the value returned by
8844 handle_single_display_spec, not just 1 or zero.
8845 (handle_single_display_spec): If the display spec is of the form
8846 `(space ...)', and specifies display in the text area, return 2
8848 (try_cursor_movement): Check for the need to scroll more
8849 accurately, and prefer exact match for point under bidi.
8850 Don't advance `row' beyond the last row of the window.
8852 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8853 into disp_prop; all users changed.
8855 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8856 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8857 for the text covered by the display property.
8859 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
8861 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

8867 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
8868 buffers, return left-to-right.
8869 (set_cursor_from_row): Consider candidate row a win if its glyph
8870 represents a newline and point is on that newline. Fixes cursor
8871 positioning on the newline at EOL of R2L text within L2R
8872 paragraph, and vice versa.
8873 (try_cursor_movement): Check continued rows, in addition to
8874 continuation rows. Fixes unwarranted scroll when point enters a
8875 continued line of R2L text within an L2R paragraph, or vice versa.
8876 (cursor_row_p): Consider the case of point being equal to
8877 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8878 from the end of a short line to the beginning of a continued line
8879 of R2L text within L2R paragraph.
8880 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8881 composed characters.
8883 * bidi.c (bidi_check_type): Use xassert.
8884 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
8887 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8889 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
8892 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
8894 * nsfont.m (ns_otf_to_script): Fix typo.
8896 2011-08-22 Kenichi Handa <handa@m17n.org>
8898 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8899 extra slot even if the purpose is char-code-property-table.
8901 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8903 * xdisp.c (redisplay_window): When computing centering_position,
8904 account for the height of the header line. (Bug#8874)
8906 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8907 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8908 candidate is selected by the mouse, and that candidate has a
8909 composed character under the mouse.
8911 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8912 coordinates reported by pos-visible-in-window-p for a composed
8913 character in column zero.
8915 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8917 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8919 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8921 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8922 consider it a hit if to_charpos is anywhere in the range of the
8923 composed buffer positions.
8925 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8927 * image.c (gif_load): Don't assume that each subimage has the same
8928 dimensions as the base image. Handle disposal method that is
8929 "undefined" by the gif spec (Bug#9335).
8931 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8933 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8934 (Fcondition_case): Document `debug' symbol in error handler.
8936 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8938 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8939 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8940 from an Org mode buffer to a Speedbar frame.
8942 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8943 a composition, take its buffer position from IT->cmp_it.charpos.
8944 Fixes cursor positioning at the beginning of a line that begins
8945 with a composed character.
8947 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8949 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8950 character bidirectional type, use STRONG_L instead. Fixes crashes
8951 in a buffer produced by `describe-categories'.
8953 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8954 members before the level stack, so they would be saved and
8955 restored when copying iterator state. Fixes incorrect reordering
8956 around TABs covered by display properties.
8958 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8960 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
8962 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
8964 * eval.c (internal_condition_case, internal_condition_case_1)
8965 (internal_condition_case_2, internal_condition_case_n):
8966 Remove unnecessary aborts (Bug#9081).
8968 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8970 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8971 has no `load' handler, try opening the file locally. (Bug#9311)
8973 2011-08-16 Ken Brown <kbrown@cornell.edu>
8975 * gmalloc.c: Expand comment.
8977 2011-08-16 Eli Zaretskii <eliz@gnu.org>
8979 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
8980 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
8982 2011-08-16 Ken Brown <kbrown@cornell.edu>
8984 Fix memory allocation problems in Cygwin build (Bug#9273).
8986 * unexcw.c ( __malloc_initialized): Declare external variable.
8987 (fixup_executable): Force the dumped emacs to reinitialize malloc.
8989 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
8991 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8993 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8995 [CYGWIN] (special_realloc): New function.
8996 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8997 requests to realloc storage in the static heap.
8999 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
9001 * bidi.c (bidi_initialize): Remove unused local.

9006 * biditype.h: Remove file.
9007 * makefile.w32-in ($(BLD)/bidi.$(O)):
9008 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
9010 * dispextern.h: Fix a typo in the comment to bidi_type_t.
9012 * chartab.c: Improve commentary for the uniprop_table API.
9014 * bidi.c (bidi_paragraph_init): Support zero value of
9015 bidi_ignore_explicit_marks_for_paragraph_level.
9016 (bidi_initialize): Use uniprop_table instead of including
9017 biditype.h and bidimirror.h.
9019 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
9020 coordinates of the iterator when restoring from ppos_it.
9023 2011-08-14 Kenichi Handa <handa@m17n.org>
9025 * process.c (create_process): Call setup_process_coding_systems
9026 after the pid of the process is set to -1 (Bug#8162).
9028 2011-08-14 Eli Zaretskii <eliz@gnu.org>
9030 * xdisp.c (move_it_in_display_line_to): Don't invoke
9031 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
9032 ppos_it. Fixes vertical cursor motion when line beginning is
9033 covered by an image. (Bug#9296)
9035 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
9037 * nsterm.h (ns_run_ascript): Declare.
9038 (NSAPP_DATA2_RUNASSCRIPT): Define.
9040 * nsfns.m (as_script, as_result, as_status): New static variables.
9041 (ns_run_ascript): New function.
9042 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
9043 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
9044 the event loop. Get status from as_status (Bug#7276).
9046 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9047 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
9048 the event loop (Bug#7276).
9050 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
9052 * gnutls.c (QCgnutls_bootprop_priority)
9053 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
9054 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
9055 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
9056 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
9057 (QCgnutls_bootprop_verify_hostname_error)
9058 (QCgnutls_bootprop_callbacks_verify): Rename from
9059 Qgnutls_bootprop_..., all uses changed.
9061 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
9064 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
9066 * xfaces.c (Qframe_set_background_mode): Now static.
9067 * dispextern.h (Qframe_set_background_mode): Remove decl.
9069 * process.c (Fnetwork_interface_info): Declare local only if needed.
9071 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
9073 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
9074 (Fnetwork_interface_list): Allocate in increments of bytes instead
9075 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
9076 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
9078 (struct ifflag_def): notrailers is smart on OSX.
9079 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9080 Get hardware address with getifaddrs if available.
9082 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9084 * xdisp.c (iterate_out_of_display_property): xassert that
9085 IT->position is set to within IT->object's boundaries. Break from
9086 the loop as soon as EOB is reached; avoids infloops in redisplay
9087 when IT->position is set up wrongly due to some bug.
9088 Set IT->current to match the bidi iterator unconditionally.
9089 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9090 entry. Force push_it to save on the stack the current
9091 buffer/string position, to be restored by pop_it. Fix flags in
9092 the iterator structure wrt the object coming from a display
9093 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9094 properties. (Bug#9284)
9096 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>

9110 * xdisp.c (forward_to_next_line_start): Allow to use the
9111 no-display-properties-and-no-overlays under bidi display.
9112 Set disp_pos in the bidi iterator to avoid searches for display
9113 properties and overlays.
9115 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9117 * editfns.c (Fset_time_zone_rule): Document relationship with the
9120 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9121 the font entity extracted from the cache (Bug#8109).
9123 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9125 * composite.c (autocmp_chars): Don't reset point. That is done by
9126 restore_point_unwind (Bug#5984).
9128 2011-08-07 Juri Linkov <juri@jurta.org>
9130 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9131 to show the arg `TIME' instead of `TIMEVAL'.
9133 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9135 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9136 display property strides EOL and includes a newline, as in
9137 longlines-mode. (Bug#9254)
9138 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9139 word-wrap under bidirectional display. (Bug#9224)
9141 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9142 is non-zero, even if the data buffer is NULL. Fixes a crash in
9143 vertical-motion with longlines-mode. (Bug#9254)
9145 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9147 * bidi.c <bidi_cache_total_alloc>: Now static.
9148 (bidi_initialize): Initialize bidi_cache_total_alloc.
9150 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9153 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9154 amount allocated this far in `bidi_cache_total_alloc'.
9155 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9156 non-zero, only free the data buffer without restoring the cache
9157 contents. All callers changed.
9159 * dispextern.h (bidi_unshelve_cache): Update prototype.
9161 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9162 (move_it_in_display_line, move_it_to)
9163 (move_it_vertically_backward, move_it_by_lines): Replace the call
9164 to xfree to an equivalent call to bidi_unshelve_cache.
9165 (move_it_in_display_line_to): Fix logic of returning
9166 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9168 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9170 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9171 came from a string character with a `cursor' property. (Bug#9229)
9173 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9175 * Makefile.in (LIB_PTHREAD): New variable.
9176 (LIBES): Add LIB_PTHREAD (Bug#9216).
9178 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9179 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9181 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9183 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9185 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9187 * xterm.c (x_find_topmost_parent): New function.
9188 (x_set_frame_alpha): Find topmost parent window with
9189 x_find_topmost_parent and set the property there also (bug#9181).
9190 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9192 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9194 * callproc.c (Fcall_process): Avoid vfork clobbering
9195 the local vars buffer, coding_systems, current_dir.
9197 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9199 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9201 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9203 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9204 so that it is not optimized away.
9206 * xdisp.c (compute_display_string_pos): Remove unused local.
9208 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9210 Fix slow cursor motion and scrolling in large buffers with
9211 selective display, like Org Mode buffers. (Bug#9218)
9213 * dispextern.h (struct bidi_it): New member disp_prop_p.
9215 * xdisp.c: Remove one-slot cache of display string positions.
9216 (compute_display_string_pos): Accept an additional argument
9217 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9218 for a display string or property. If found, set DISP_PROP_P
9221 * bidi.c (bidi_fetch_char): Accept an additional argument
9222 DISP_PROP_P, and pass it to compute_display_string_pos.
9223 Only handle text covered by a display string if DISP_PROP_P is returned
9224 non-zero. All callers of bidi_fetch_char changed.
9226 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9228 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9230 2010-12-03 Don March <don@ohspite.net>
9232 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9233 last character M-[char] is translated to ESC [char] (bug#7541).
9235 2011-08-02 Kenichi Handa <handa@m17n.org>
9237 * lisp.h (uniprop_table): Extern it.
9239 * chartab.c (uniprop_table): Make it non-static.
9241 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9243 * xdisp.c (forward_to_next_line_start): Accept additional argument
9244 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9246 (reseat_at_next_visible_line_start): Use the bidi iterator state
9247 returned by forward_to_next_line_start to restore the state of
9248 it->bidi_it after backing up to previous newline. (Bug#9212)
9250 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9252 * regex.c (re_comp): Protoize.
9253 (re_exec): Fix return type.
9254 (regexec): Fix type of `ret'. (Bug#9203)
9256 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9258 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9259 This is needed if max-image-size is a floating-point number.
9261 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9263 * print.c (print_object): Print empty symbol as ##.
9265 * lread.c (read1): Read ## as empty symbol.
9267 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9269 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9270 setting frame foreground color (Bug#9175).
9271 (x_set_background_color): Likewise.
9273 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9274 contents (Bug#9176).
9275 (EmacsTooltip -init): Remove bezels and add shadows to
9278 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9279 or scroll bar (Bug#8470).
9281 * nsfont.m (nsfont_open): Remove assignment to voffset and
9282 unnecessary vars hshink, expand, hd, full_height, min_height.
9283 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9285 * nsterm.h (nsfont_info): Remove voffset field.
9287 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9289 Implement strike-through and overline on NextStep (Bug#8863).
9291 * nsfont.m (nsfont_open): Use underline position provided by font,
9292 instead of hard-coded value of 2.
9293 (nsfont_draw): Call ns_draw_text_decoration instead.
9295 * nsterm.h: Add declaration for ns_draw_text_decoration.
9297 * nsterm.m (ns_draw_text_decoration): New function for drawing
9298 underline, overline, and strike-through.
9299 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9300 ns_draw_text_decoration. Change treatment of cursor drawing to
9301 accommodate underlining, etc.
9303 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9305 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9308 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9310 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9311 Without this fix, if a signal arrives just after memory fills up,
9312 'malloc' might be invoked reentrantly.
9314 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9315 In other words, assume that every image size is allowed, on non-X
9316 hosts. This assumption is probably wrong, but it lets Emacs compile.
9318 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9320 * regex.c (re_iswctype): Convert return values to boolean.
9322 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9324 * xdisp.c (compute_display_string_pos): Don't use cached display
9325 string position if the buffer had its restriction changed.
9328 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9330 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9332 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9334 Integer signedness and overflow and related fixes. (Bug#9079)
9336 * bidi.c: Integer size and overflow fixes.
9337 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9338 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9339 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9340 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9341 (bidi_find_other_level_edge):
9342 Use ptrdiff_t instead of EMACS_INT where either will do.
9343 This works better on 32-bit hosts configured --with-wide-int.
9344 (bidi_cache_ensure_space): Check for size-calculation overflow.
9345 Use % rather than repeated addition, for better worst-case speed.
9346 Don't set bidi_cache_size until after xrealloc returns, because it
9348 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9349 (bidi_cache_ensure_space): Also check that the bidi cache size
9350 does not exceed that of the largest Lisp string or buffer. See Eli
9351 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9353 * alloc.c (__malloc_size_t): Remove.
9354 All uses replaced by size_t. See Andreas Schwab's note
9355 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9357 * image.c: Improve checking for integer overflow.
9358 (check_image_size): Assume that f is nonnull, since
9359 it is always nonnull in practice. This is one less thing to
9360 worry about when checking for integer overflow later.
9361 (x_check_image_size): New function, which checks for integer
9362 overflow issues inside X.
9363 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9364 This removes the need for a memory_full check.
9365 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9366 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9367 (xbm_read_bitmap_data): Change locals back to 'int', since
9368 their values must fit in 'int'.
9369 (xpm_load_image, png_load, tiff_load):
9370 Invoke x_create_x_image_and_pixmap earlier,
9371 to avoid much needless work if the image is too large.
9372 (tiff_load): Treat overly large images as if
9373 x_create_x_image_and_pixmap failed, not as malloc failures.
9374 (gs_load): Use x_check_image_size.
9376 * gtkutil.c: Omit integer casts.
9377 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9378 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9380 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9382 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9383 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9384 would wrongly return t on a 64-bit host.
9386 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9387 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9388 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9389 and therefore cause GCC to emit a bogus diagnostic in some cases.
9391 * image.c: Integer signedness and overflow and related fixes.
9392 This is not an exhaustive set of fixes, but it's time to
9393 record what I've got.
9394 (lookup_pixel_color, check_image_size): Remove redundant decls.
9395 (check_image_size): Don't assume that arbitrary EMACS_INT values
9396 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9397 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9398 (tiff_load, imagemagick_load_image):
9399 Check for overflow in size calculations.
9400 (x_create_x_image_and_pixmap): Remove unnecessary test for
9401 xmalloc returning NULL; that can't happen.
9402 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9403 (xpm_color_bucket): Use better integer hashing function.
9404 (xpm_cache_color): Don't possibly over-allocate memory.
9405 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9406 (gif_memory_source):
9407 Use ptrdiff_t, not int or size_t, to record sizes.
9408 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9409 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9410 either works, as we prefer signed integers.
9411 (tiff_read_from_memory, tiff_write_from_memory):
9412 Return tsize_t, not size_t, since that's what the TIFF API wants.
9413 (tiff_read_from_memory): Don't fail simply because the read would
9414 go past EOF; instead, return a short read.
9415 (tiff_load): Omit no-longer-needed casts.
9416 (Fimagemagick_types): Don't assume size fits into 'int'.
9418 Improve hashing quality when configured --with-wide-int.
9419 * fns.c (hash_string): New function, taken from sxhash_string.
9420 Do not discard information about ASCII character case; this
9421 discarding is no longer needed.
9422 (sxhash-string): Use it. Change sig to match it. Caller changed.
9423 * lisp.h: Declare it.
9424 * lread.c (hash_string): Remove, since we now use fns.c's version.
9425 The fns.c version returns a wider integer if --with-wide-int is
9426 specified, so this should help the quality of the hashing a bit.
9428 * emacs.c: Integer overflow minor fix.
9429 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9430 Define only if GNU_LINUX.
9431 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9433 * dispnew.c: Integer signedness and overflow fixes.
9434 Remove unnecessary forward decls, that were a maintenance hassle.
9435 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9437 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9438 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9439 (prepare_desired_row, line_draw_cost):
9440 Use int, not unsigned, where either works.
9441 (save_current_matrix, restore_current_matrix):
9442 Use ptrdiff_t, not size_t, where either works.
9443 (init_display): Check for overflow more accurately, and without
9444 relying on undefined behavior.
9446 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9447 Remove, replacing with the new symbols in lisp.h. All uses changed.
9448 * fileio.c (make_temp_name):
9449 * filelock.c (lock_file_1, lock_file):
9450 * xdisp.c (message_dolog):
9451 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9452 Use pMd etc. instead.
9453 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9454 replacing the pWIDE etc. symbols removed from editfns.c.
9456 * keyboard.h (num_input_events): Now uintmax_t.
9457 This is (very slightly) less likely to mess up due to wraparound.
9460 * buffer.c: Integer signedness fixes.
9461 (alloc_buffer_text, enlarge_buffer_text):
9462 Use ptrdiff_t rather than size_t when either will do, as we prefer
9465 * alloc.c: Integer signedness and overflow fixes.
9466 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9467 (__malloc_size_t): Default to size_t, not to int.
9468 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9469 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9470 Prefer ptrdiff_t to size_t when either would do, as we prefer
9472 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9473 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9474 Now const. Initialize with values that are in range even if char
9476 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9477 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9478 These functions do the right thing with sizes > 2**32.
9479 (check_depth): Now ptrdiff_t, not int.
9480 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9481 Adjust to new way of storing sizes. Check for size overflow bugs
9483 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9484 slightly wrong anyway, as it missed one instance of
9485 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9486 (refill_memory_reserve): Omit needless cast to size_t.
9487 (mark_object_loop_halt): Mark as externally visible.
9489 * xselect.c: Integer signedness and overflow fixes.
9490 (Fx_register_dnd_atom, x_handle_dnd_message):
9491 Use ptrdiff_t, not size_t, since we prefer signed.
9492 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9493 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9494 x_dnd_atoms_size and x_dnd_atoms_length.
9496 * doprnt.c: Prefer signed to unsigned when either works.
9498 * doprnt.c (doprnt):
9500 * xdisp.c (vmessage):
9501 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9502 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9503 prefer signed arithmetic to avoid comparison confusion.
9504 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9505 but is a bit tricky.
9507 Assume freestanding C89 headers, string.h, stdlib.h.
9508 * data.c, doprnt.c, floatfns.c, print.c:
9509 Include float.h unconditionally.
9510 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9511 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9512 * regex.c: Likewise for stddef.h, string.h.
9513 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9514 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9515 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9516 (STDC_HEADERS): Remove obsolete defines.
9517 * sysdep.c: Include limits.h unconditionally.
9519 Assume support for memcmp, memcpy, memmove, memset.
9520 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9521 * regex.c (memcmp, memcpy):
9522 Remove; we assume C89 now.
9524 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9525 (__malloc_safe_bcopy): Remove; no longer needed.
9527 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9528 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9529 well either way, and we prefer signed to unsigned.
9531 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9533 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9534 closes the connection while we're reading (bug#9182).
9536 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9538 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9539 are specified (Bug#9168).
9541 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9543 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9544 Found by GCC static checking and --with-wide-int on a 32-bit host.
9546 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9548 * xdisp.c (compute_display_string_pos): Fix logic of caching
9549 previous display string position. Initialize cached_prev_pos to
9550 -1. Fixes slow-down at the beginning of a buffer.
9552 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9554 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9555 for attrs[LFACE_FONTSET_INDEX].
9557 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9559 * xml.c (parse_region): Remove unused local
9560 that was recently introduced.
9562 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9564 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9565 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9567 * xdisp.c (move_it_in_display_line_to): Record the best matching
9568 position for TO_CHARPOS while scanning the line, and restore it on
9569 exit if none of the characters scanned was an exact match.
9570 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9571 when exact match is impossible due to invisible text, and the
9572 lines are truncated.
9574 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9576 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9579 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9581 Fix a significant slow-down of cursor motion with C-n, C-p,
9582 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9583 auto-repeat under bidi redisplay in fontified buffers.
9584 * xdisp.c (compute_stop_pos_backwards): New function.
9585 (next_element_from_buffer): Call compute_stop_pos_backwards to
9586 find a suitable prev_stop when we find ourselves before
9588 (reseat): Don't look for prev_stop, as that could mean a very long
9590 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9591 <cached_disp_overlay_modiff>: Cache for last found display string
9593 (compute_display_string_pos): Return the cached position if asked
9594 about the same buffer in the same area of character positions, and
9595 the buffer wasn't changed since the time the display string
9596 position was cached.
9598 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9600 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9601 is an integer, which is important for empty lines. (Bug#9149)
9603 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9605 * frame.c (Fmodify_frame_parameters): In tty case, update the
9606 default face if necessary (Bug#4238).
9608 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9610 * editfns.c (Fstring_to_char): No need to explain what a character
9611 is in the docstring (Bug#6576).
9613 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9615 * xml.c (parse_region): Make sure we always return a tree.
9617 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9619 * xml.c (parse_region): If a document contains only comments,
9622 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9624 * xml.c (make_dom): Return comments, too.
9626 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9629 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9630 and the surrounding thread.
9631 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9632 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9633 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9635 * s/openbsd.h (BROKEN_SIGIO): Define.
9636 * unexelf.c (unexec) [__OpenBSD__]:
9637 Don't update the .mdebug section of the Alpha COFF symbol table.
9639 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9641 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9644 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9646 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9647 This fixes some race conditions on the permissions of any newly
9650 * alloc.c (valid_pointer_p): Use pipe, not open.
9651 This fixes some permissions issues when debugging.
9653 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9654 If fchown fails to set both uid and gid, try to set just gid,
9655 as that is sometimes allowed. Adjust the file's mode to eliminate
9656 setuid or setgid bits that are inappropriate if fchown fails.
9658 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9660 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9661 to compare Lisp_Objects.
9662 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9663 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9664 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9666 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9668 * lread.c (read_integer): Unread even EOF character.

9671 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9672 symbol character follows.
9674 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9676 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9677 This works around a problem with the previous change to Fcopy_file.
9678 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9679 and without this change, GCC might complain about discarding
9680 fchown's return value.
9682 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9684 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9686 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9688 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9690 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9692 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9693 it's used from the C level.
9695 * process.c: Use the same condition for POLL_FOR_INPUT in both
9696 keyboard.c and process.c (bug#1858).
9698 2011-07-09 Lawrence Mitchell <wence@gmx.li>

9701 (Fgnutls_boot): Use it.
9703 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9705 * doc.c (Fsubstitute_command_keys): Revert last change.
9707 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9709 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9710 quotes the next character, and doesn't affect other longer
9711 sequences (bug#8935).
9713 * lread.c (syms_of_lread): Clarify that is isn't only
9714 `eval-buffer' and `eval-defun' that's affected by
9715 `lexical-binding' (bug#8460).
9717 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9719 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9720 bidi redisplay when a line includes both an image and is truncated.
9722 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9724 Fix minor problems found by static checking.
9725 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9726 (elsz): Now a signed constant, not a size_t var. We prefer signed
9727 types to unsigned, to avoid integer comparison confusion. Without
9728 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9729 "cannot optimize loop, the loop counter may overflow", a symptom
9731 * indent.c (Fvertical_motion): Mark locals as initialized.
9732 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9734 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9736 * search.c (Fre_search_backward): Mention `case-fold-search' in
9737 all the re_search_* functions (bug#8138).
9739 * keyboard.c (Fopen_dribble_file): Document when the file is

9755 Initialize itb.string.lstring.
9756 (init_iterator): Call bidi_init_it only of a valid
9757 buffer position was specified. Initialize paragraph_embedding to
9759 (reseat_to_string): Initialize the bidi iterator.
9760 (display_string): If we need to ignore text properties of
9761 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

9766 (compute_display_string_end): Support display properties on Lisp
9768 (init_iterator, reseat_1, reseat_to_string): Initialize the
9769 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9770 when iterating on a string not from display properties).
9771 (compute_display_string_pos, compute_display_string_end):
9772 Fix calculation of the object to scan. Fixes an error when using
9774 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9775 base_level_stop; instead, set base_level_stop to BEGV.
9776 Fixes crashes in vertical-motion.
9777 (next_element_from_buffer): Improve commentary for when
9778 the iterator is before prev_stop.
9779 (init_iterator): Initialize bidi_p from the default value of
9780 bidi-display-reordering, not from buffer-local value. Use the
9781 buffer-local value only if initializing for buffer iteration.
9782 (handle_invisible_prop): Support invisible properties on strings
9783 that are being bidi-reordered.
9784 (set_iterator_to_next): Support bidi reordering of C strings and

9800 character that is not the first one in the visual order.
9801 (get_visually_first_element): New function, refactored from common
9802 parts of next_element_from_buffer, next_element_from_string, and
9803 next_element_from_c_string.
9804 (tool_bar_lines_needed, redisplay_tool_bar)
9805 (display_menu_bar): Force left-to-right direction. Add a FIXME
9806 comment for making that be controlled by a user option.

9820 pushed the iterator stack, restore the internal state of the bidi
9821 iterator by calling bidi_pop_it same number of times.
9822 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9823 and we are bidi-iterating, don't decrement the iterator position;
9824 instead, set the first_elt flag in the bidi iterator, to produce
9826 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9827 (push_display_prop): xassert that we are iterating a buffer.
9828 (push_it, pop_it): Save and restore paragraph_embedding member.

9834 (compute_display_string_end): Fix handling the case of C string.
9835 (push_it, pop_it): Save and restore from_disp_prop_p.
9836 (handle_single_display_spec, push_display_prop): Set the
9837 from_disp_prop_p flag.
9838 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9860 (back_to_previous_visible_line_start, reseat_1)
9861 (init_iterator): Empty the bidi cache "stack".
9862 (move_it_in_display_line_to): If iterator ended up at

9873 Save and restore bidi cache.
9875 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9876 (bidi_paragraph_info): Delete unused struct.
9877 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9878 (bidi_cache_start): New variable.

9885 (bidi_move_to_visually_next): Compare cache index with
9886 bidi_cache_start rather than with zero.
9887 (bidi_fetch_char): Accept new argument STRING; all callers
9888 changed. Support iteration over a string. Support strings with
9889 display properties. Support unibyte strings. Fix the type of
9890 `len' according to what STRING_CHAR_AND_LENGTH expects.
9891 (bidi_paragraph_init, bidi_resolve_explicit_1)

9989 The old code sometimes used this field without initializing it.
9991 * alloc.c (gc_sweep): Don't read past end of array.
9992 In theory, the old code could also have corrupted Emacs internals,
9993 though it'd be very unlikely.

9997 * character.c (Fcharacterp): Don't advertise optional ignored
9998 argument. (Bug#4026)

10012 * xsettings.c (store_monospaced_changed): Define this function only
10013 if (defined HAVE_GSETTINGS || defined HAVE_GCONF), as it's
10014 not used otherwise.

10256 (clone_per_buffer_values): Don't assume that
10257 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
10258 This isn't true in general, and it's particularly not true
10259 if Emacs is configured with --with-wide-int.
10260 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
10261 New macros, used in the buffer.c change.

10297 Random fixes. E.g., (random) never returned negative values.
10298 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10299 subseconds part to the entropy, as that's a bit more random.
10300 Prefer signed to unsigned, since the signedness doesn't matter and
10301 in general we prefer signed. When given a limit, use a
10302 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10303 latter isn't right if USE_2_TAGS_FOR_INTS.
10304 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10305 not 0..VALMASK. Don't discard "excess" bits that random () returns.
10307 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10309 * textprop.c (text_property_stickiness):
10310 Obey Vtext_property_default_nonsticky.

10317 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
10318 This is more efficient than Ffile_directory_p and avoids a minor race.
10320 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
10322 * buffer.c (Foverlay_put): Say what the return value is
10325 * fileio.c (barf_or_query_if_file_exists): Check first if the file
10326 is a directory before asking whether to use the file name
10328 (barf_or_query_if_file_exists): Make the "File is a directory"
10329 error be more correct.
10331 * fns.c (Frequire): Remove the mention of the .gz files, since
10332 that's installation-specific, but keep the mention of
10333 `get-load-suffixes'.
10335 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
10337 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

10345 Qgnutls_bootprop_verify_error (which is no longer used).
10347 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
10348 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
10349 Also (re)move comments that are misplaced or no longer relevant.
10351 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10353 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

10371 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
10373 * keyboard.c (command_loop_1): If a down-mouse event is unbound,
10374 leave any prefix arg for the up event (Bug#1586).
10376 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
10378 * lread.c (syms_of_lread): Mention single symbols defined by
10379 `defvar' or `defconst' (bug#7154).
10381 * fns.c (Frequire): Mention .el.gz files (bug#7314).
10382 (Frequire): Mention get-load-suffixes.
10384 2011-07-02 Martin Rudalics <rudalics@gmx.at>
10386 * window.h (window): Remove clone_number slot.
10387 * window.c (Fwindow_clone_number, Fset_window_clone_number):

10405 (Fcopy_keymap): Handle embedded parents.
10406 (Fcommand_remapping, define_as_prefix): Simplify.
10407 (Fkey_binding): Simplify.

10409 minibuffer-local-filename-completion-map,
10410 minibuffer-local-must-match-map, and
10411 minibuffer-local-filename-must-match-map to Elisp.
10412 (syms_of_keymap): Defsubr make-composed-keymap.
10413 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
10414 (parse_menu_item): Trivial simplification.
10416 2011-07-01 Glenn Morris <rgm@gnu.org>
10418 * Makefile.in (SETTINGS_LIBS): Fix typo.

10442 (xgselect_initialize): Ditto.
10444 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h
10445 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
10448 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
10450 * eval.c (struct backtrace): Simplify and port the data structure.
10451 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10452 signed bit field, as this assumption is not portable and it makes
10453 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10454 "char debug_on_exit : 1" as this is not portable either; instead,
10455 use the portable "unsigned int debug_on_exit : 1". Remove unused
10456 member evalargs. Remove obsolete comments about cc bombing out.
10458 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

10624 * print.c (printchar, strout): Check for string overflow.
10625 (PRINTPREPARE, printchar, strout):
10626 Don't set size unless allocation succeeds.
10628 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10629 for sizes. Check for string overflow more accurately.
10630 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10632 * macros.c: Integer and buffer overflow fixes.
10633 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10634 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

10638 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10640 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10642 * lread.c: Integer overflow fixes.
10643 (read_integer): Radix is now EMACS_INT, not int,
10644 to improve quality of diagnostics for out-of-range radices.
10645 Calculate buffer size correctly for out-of-range radices.
10646 (read1): Check for integer overflow in radices, and in
10647 read-circle numbers.
10648 (read_escape): Avoid int overflow.
10649 (Fload, openp, read_buffer_size, read1)
10650 (substitute_object_recurse, read_vector, read_list, map_obarray):
10651 Use ptrdiff_t, not int, for sizes.

10666 2011-06-22 Leo Liu <sdl.web@gmail.com>
10668 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10669 Move to minibuffer.el.
10671 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10673 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10674 The following patches are for when GLYPH_DEBUG && !XASSERT.
10675 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10676 * dispnew.c (flush_stdout):
10677 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10678 Mark as externally visible.
10679 * dispnew.c (check_window_matrix_pointers): Now static.
10680 * dispnew.c (window_to_frame_vpos):
10681 * xfns.c (unwind_create_frame):

10683 * scroll.c (CHECK_BOUNDS):
10684 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10685 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10686 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10687 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10688 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10690 (debug_method_add): Use va_list and vsprintf rather than relying
10691 on undefined behavior with wrong number of arguments.
10692 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10693 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10694 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10695 since we're not interested in debugging glyphs with old libraries.
10696 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10697 GCC 4.6.0's static checking.
10699 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10701 Integer overflow and signedness fixes (Bug#8873).

10717 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10718 (.bitmaps_last, struct x_output.icon_bitmap):
10719 Use ptrdiff_t, not int, for bitmap indexes.
10720 (x_allocate_bitmap_record): Check for size overflow.
10721 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10723 Use ptrdiff_t, not int, for overlay counts.
10724 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10725 * editfns.c (overlays_around, get_pos_property):
10726 * textprop.c (get_char_property_and_overlay):
10727 * xdisp.c (next_overlay_change, note_mouse_highlight):
10728 * xfaces.c (face_at_buffer_position):
10729 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10730 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10731 (Fnext_overlay_change, Fprevious_overlay_change)
10732 (mouse_face_overlay_overlaps, Foverlays_in):
10733 Use ptrdiff_t, not int, for sizes.
10734 (overlays_at, overlays_in): Check for size-calculation overflow.
10736 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10738 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10739 (x_session_initialize): Do not assume string length fits in int.
10741 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10742 This is unlikely, but can occur if DPI is outlandish.
10744 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10745 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10747 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10748 * xrdb.c (magic_file_p, search_magic_path):
10749 Omit last arg SUFFIX; it was always 0. All callers changed.
10750 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10752 * xfont.c (xfont_match): Avoid need for strlen.
10754 * xfns.c: Don't assume strlen fits in int.

10757 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10758 not unsigned long, as we prefer signed integers. All callers changed.
10759 Detect integer overflow in repeat count.
10760 (message_dolog): Don't assume print length fits in 39 bytes.
10761 (display_mode_element): Don't assume strlen fits in int.
10763 * termcap.c: Don't assume sizes fit in int and never overflow.
10764 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10765 (gobble_line): Check for size-calculation overflow.
10767 * minibuf.c (Fread_buffer):
10768 * lread.c (intern, intern_c_string):
10769 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

10782 * filelock.c: Fix some buffer overrun and integer overflow issues.
10783 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10784 Reformulate so as not to need the command string.
10785 Invoke gzip -cd rather than gunzip, as it's more portable.
10786 (lock_info_type, lock_file_1, lock_file):
10787 Don't assume pid_t and time_t fit in unsigned long.
10788 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10789 (current_lock_owner): Prefer signed type for sizes.
10790 Use memcpy, not strncpy, where memcpy is what is really wanted.
10791 Don't assume (via atoi) that time_t and pid_t fit in int.
10792 Check for time_t and/or pid_t out of range, e.g., via a network share.
10793 Don't alloca where an auto var works fine.
10795 * fileio.c: Fix some integer overflow issues.
10796 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10797 Don't assume string length fits in int.
10798 (directory_file_name): Don't assume string length fits in long.
10799 (make_temp_name): Don't assume pid fits in int, or that its print
10800 length is less than 20.
10802 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10804 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10806 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

10819 (Fgetenv_internal):
10820 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10822 * lread.c (invalid_syntax): Omit length argument.
10823 All uses changed. This doesn't fix a bug, but it simplifies the
10824 code away from its former Hollerith-constant appearance, and it's
10825 one less 'int' to worry about when looking at integer-overflow issues.
10826 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10828 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10829 This didn't break anything, but it didn't help either.
10830 It's confusing to put a bogus integer in a place where the actual
10831 value does not matter.
10832 (LIST_END_P): Remove unused macro and its bogus comment.
10833 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10835 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10836 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10838 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10839 We prefer signed types, and the value cannot exceed the EMACS_INT
10840 range anyway (because otherwise the length would not be representable).
10841 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10842 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10843 This avoids a GCC warning when WIDE_EMACS_INT.
10845 * indent.c (sane_tab_width): New function.
10846 (current_column, scan_for_column, Findent_to, position_indentation)
10847 (compute_motion): Use it. This is just for clarity.
10848 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10850 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10852 * lisp.h (lint_assume): New macro.
10853 * composite.c (composition_gstring_put_cache):
10854 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10856 * editfns.c, insdel.c:
10857 Omit unnecessary forward decls, to simplify future changes.
10859 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10861 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10863 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10864 Use much-faster test for byte-length change.
10865 Don't assume string byte-length fits in 'int'.
10866 Check that character arg fits in 'int'.
10867 (mapcar1): Declare byte as byte, for clarity.
10869 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10871 * fns.c (concat): Catch string overflow earlier.
10872 Do not rely on integer wraparound.
10874 * dispextern.h (struct it.overlay_strings_charpos)
10875 (struct it.selective): Now EMACS_INT, not int.
10876 * xdisp.c (forward_to_next_line_start)
10877 (back_to_previous_visible_line_start)
10878 (reseat_at_next_visible_line_start, next_element_from_buffer):
10879 Don't arbitrarily truncate the value of 'selective' to int.
10881 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10883 * composite.c: Don't truncate sizes to 'int'.
10884 (composition_gstring_p, composition_reseat_it)
10885 (composition_adjust_point): Use EMACS_INT, not int.
10886 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10887 not EMACS_UINT, for indexes.
10889 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10891 * buffer.c: Include <verify.h>.
10892 (struct sortvec.priority, struct sortstr.priority):
10893 Now EMACS_INT, not int.
10894 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10895 (struct sortstr.size, record_overlay_string)
10896 (struct sortstrlist.size, struct sortlist.used):
10897 Don't truncate size to int.
10898 (record_overlay_string): Check for size-calculation overflow.
10899 (init_buffer_once): Check at compile-time, not run-time.
10901 2011-06-22 Jim Meyering <meyering@redhat.com>
10903 Don't leak an XBM-image-sized buffer
10904 * image.c (xbm_load): Free the image buffer after using it.
10906 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10909 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10910 that Sun C diagnosed.
10911 * fns.c (secure_hash): Fix pointer signedness issue.
10912 * intervals.c (static_offset_intervals): New function.
10913 (offset_intervals): Use it.
10915 2011-06-21 Leo Liu <sdl.web@gmail.com>
10918 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10921 * fns.c (secure_hash): Rename from crypto_hash_function and change
10922 the first arg to accept symbols.
10923 (Fsecure_hash): New primitive.
10924 (syms_of_fns): New symbols.
10926 2011-06-20 Deniz Dogan <deniz@dogan.se>
10928 * process.c (Fset_process_buffer): Clarify return value in
10931 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10933 * dispnew.c (add_window_display_history): Use BVAR.
10935 * xdisp.c (debug_method_add): Use BVAR.
10936 (check_window_end, dump_glyph_matrix, dump_glyph)
10937 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10939 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10942 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10943 check till after the cache is created in init_frame_faces.
10945 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10947 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10949 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10951 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10952 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10953 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10955 Improve buffer-overflow checking (Bug#8873).
10956 * fileio.c (Finsert_file_contents):
10957 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10958 Remove the old (too-loose) buffer overflow checks.
10959 They weren't needed, since make_gap checks for buffer overflow.
10960 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10961 The old code merely checked for Emacs fixnum overflow, and relied
10962 on undefined (wraparound) behavior. The new code avoids undefined
10963 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10965 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10966 Tune. Don't use wider integers than needed. Don't use alloca.
10967 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10969 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10971 * insdel.c, lisp.h (buffer_overflow): New function.
10972 (insert_from_buffer_1, replace_range, replace_range_2):
10973 * insdel.c (make_gap_larger):
10974 * editfns.c (Finsert_char):
10975 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10977 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10979 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10981 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10983 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10984 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10986 * fileio.c: Don't assume EMACS_INT fits in off_t.
10987 (emacs_lseek): New static function.
10988 (Finsert_file_contents, Fwrite_region): Use it.
10989 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10991 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10993 * fns.c: Don't overflow int when computing a list length.
10994 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10995 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10996 truncation on 64-bit hosts. Check for QUIT every
10997 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10998 faster and is responsive enough.
10999 (Flength): Report an error instead of overflowing an integer.
11000 (Fsafe_length): Return a float if the value is not representable
11001 as a fixnum. This shouldn't happen except in contrived situations.
11002 (Fnthcdr, Fsort): Don't assume list length fits in int.
11003 (Fcopy_sequence): Don't assume vector length fits in int.
11005 * alloc.c: Check that resized vectors' lengths fit in fixnums.
11006 (header_size, word_size): New constants.
11007 (allocate_vectorlike): Don't check size overflow here.
11008 (allocate_vector): Check it here instead, since this is the only
11009 caller of allocate_vectorlike that could cause overflow.
11010 Check that the new vector's length is representable as a fixnum.
11012 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11013 The previous code was bogus. For example, next_almost_prime (32)
11014 returned 39, which is undesirable as it is a multiple of 3; and
11015 next_almost_prime (24) returned 25, which is a multiple of 5 so
11016 why was the code bothering to check for multiples of 7?
11018 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11020 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11022 Variadic C functions now count arguments with ptrdiff_t.
11023 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11024 Back then I didn't know that the Emacs coding style prefers signed int.
11025 Also, in the meantime I found a few more instances where arguments
11026 were being counted with int, which may truncate counts on 64-bit
11027 machines, or EMACS_INT, which may be unnecessarily wide.
11028 * lisp.h (struct Lisp_Subr.function.aMANY)
11029 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11030 Arg counts are now ptrdiff_t, not size_t.
11031 All variadic functions and their callers changed accordingly.
11032 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11033 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11034 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11035 * callint.c (Fcall_interactively): Check arg count for overflow,
11036 to avoid potential buffer overrun. Use signed char, not 'int',
11037 for 'varies' array, so that we needn't bother to check its size
11038 calculation for overflow.
11039 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11040 * eval.c (apply_lambda):
11041 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11042 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11043 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11045 * callint.c (Fcall_interactively): Don't use index var as event count.
11047 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11048 * mem-limits.h (SIZE): Remove; no longer used.
11050 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11052 Remove unnecessary casts.
11053 * xterm.c (x_term_init):
11054 * xfns.c (x_set_border_pixel):
11055 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11056 These aren't needed now that we assume ANSI C.
11058 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11059 It's more likely to cause problems (due to unsigned overflow)
11062 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11064 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11066 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11068 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11070 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11072 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11074 GLYPH_CODE_FACE returns EMACS_INT, not int.
11075 * dispextern.h (merge_faces):
11076 * xfaces.c (merge_faces):
11077 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11078 Don't assume EMACS_INT fits in int.
11080 * character.h (CHAR_VALID_P): Remove unused parameter.
11081 * fontset.c, lisp.h, xdisp.c: All uses changed.
11083 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11085 * fns.c (concat): Minor tuning based on overflow analysis.
11086 This doesn't fix any bugs. Use int to hold character, instead
11087 of constantly refetching from Emacs object. Use XFASTINT, not
11088 XINT, for value known to be a character. Don't bother comparing
11089 a single byte to 0400, as it's always less.
11091 * floatfns.c (Fexpt):
11092 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11094 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11097 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11099 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11100 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11101 incorrectly succeed when S was a string, because 4294967386 was
11102 truncated before it was used.
11104 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11105 Otherwise, an out-of-range integer could cause undefined behavior
11108 * composite.c: Use int, not EMACS_INT, for characters.
11109 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11110 EMACS_INT, for values that are known to be in character range.
11111 This doesn't fix any bugs but is the usual style inside Emacs and
11112 may generate better code on 32-bit machines.
11114 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11115 This is for reasons similar to the recent CHAR_STRING fix.
11116 * charset.c (Fencode_char): Check that character arg is actually
11117 a character. Pass an int to ENCODE_CHAR.
11118 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11119 wider than 'int', as a compile-time check to prevent future regressions
11122 * character.c (char_string): Remove unnecessary casts.
11124 Make sure a 64-bit char is never passed to CHAR_STRING.
11125 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11126 by silently ignoring the top 32 bits, allowing some values
11127 that were far too large to be valid characters.
11128 * character.h: Include <verify.h>.
11129 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11130 arguments are no wider than unsigned, as a compile-time check
11131 to prevent future regressions in this area.
11133 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11134 (Fsubst_char_in_region):
11136 * xdisp.c (decode_mode_spec_coding):
11137 Adjust to CHAR_STRING's new requirement.
11138 * editfns.c (Finsert_char, Fsubst_char_in_region):
11139 * fns.c (concat): Check that character args are actually
11140 characters. Without this test, these functions did the wrong
11141 thing with wildly out-of-range values on 64-bit hosts.
11143 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11144 These casts should not be needed on 32-bit hosts, either.
11145 * keyboard.c (read_char):
11146 * lread.c (Fload): Remove casts to unsigned.
11148 * lisp.h (UNSIGNED_CMP): New macro.
11149 This fixes comparison bugs on 64-bit hosts.
11150 (ASCII_CHAR_P): Use it.
11151 * casefiddle.c (casify_object):
11152 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11153 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11154 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11155 * dispextern.h (FACE_FROM_ID):
11156 * keyboard.c (read_char): Use UNSIGNED_CMP.
11158 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11159 not to EMACS_INT, to avoid GCC warning.
11161 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11163 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11164 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11165 isn't needed on 32-bit machines.
11167 * buffer.c (Fgenerate_new_buffer_name):
11168 Use EMACS_INT for count, not int.
11169 (advance_to_char_boundary): Return EMACS_INT, not int.
11171 * data.c (Qcompiled_function): Now static.
11173 * window.c (window_body_lines): Now static.
11175 * image.c (gif_load): Rename local to avoid shadowing.
11177 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11178 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11179 * alloc.c (make_save_value): Integer argument is now of type
11180 ptrdiff_t, not int.
11181 (mark_object): Use ptrdiff_t, not int.
11182 * lisp.h (pD): New macro.
11183 * print.c (print_object): Use it.
11185 * alloc.c: Use EMACS_INT, not int, to count objects.
11186 (total_conses, total_markers, total_symbols, total_vector_size)
11187 (total_free_conses, total_free_markers, total_free_symbols)
11188 (total_free_floats, total_floats, total_free_intervals)
11189 (total_intervals, total_strings, total_free_strings):
11190 Now EMACS_INT, not int. All uses changed.
11191 (Fgarbage_collect): Compute overall total using a double, so that
11192 integer overflow is less likely to be a problem. Check for overflow
11193 when converting back to an integer.
11194 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11195 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11196 These were 'int' variables that could overflow on 64-bit hosts;
11197 they were never used, so remove them instead of repairing them.
11198 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11199 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
11200 Previously, this ceilinged at INT_MAX, but that doesn't work on
11202 (allocate_pseudovector): Don't use EMACS_INT when int would do.
11204 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
11205 (allocate_vectorlike): Check for ptrdiff_t overflow.
11206 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
11207 when a (possibly-narrower) signed value would do just as well.
11208 We prefer using signed arithmetic, to avoid comparison confusion.
11210 * alloc.c: Catch some string size overflows that we were missing.
11211 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
11212 for convenience in STRING_BYTES_MAX.
11213 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11214 The definition here is exact; the one in lisp.h was approximate.
11215 (allocate_string_data): Check for string overflow. This catches
11216 some instances we weren't catching before. Also, it catches
11217 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11218 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11219 and ptrdiff_t and EMACS_INT are both 64 bits.
11221 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11222 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
11223 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
11225 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
11227 * alloc.c (Fmake_string): Check for out-of-range init.
11229 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
11231 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
11233 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
11235 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
11236 xg_get_default_scrollbar_width.
11238 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
11239 (int_gtk_range_get_value): Move to the scroll bar part of the file.
11240 (style_changed_cb): Call update_theme_scrollbar_width and call
11241 x_set_scroll_bar_default_width and xg_frame_set_char_size for
11242 all frames (Bug#8505).
11243 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
11244 Call gtk_window_set_resizable if HAVE_GTK3.
11245 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
11246 and height if HAVE_GTK3 (Bug#8505).
11247 (scroll_bar_width_for_theme): New variable.
11248 (update_theme_scrollbar_width): New function.
11249 (xg_get_default_scrollbar_width): Move code to
11250 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
11251 (xg_initialize): Call update_theme_scrollbar_width.
11253 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
11255 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
11257 2011-06-12 Martin Rudalics <rudalics@gmx.at>
11259 * frame.c (make_frame): Call other_buffer_safely instead of
11262 * window.c (temp_output_buffer_show): Call display_buffer with
11263 second argument Vtemp_buffer_show_specifiers and reset latter
11264 immediately after the call.
11265 (Vtemp_buffer_show_specifiers): New variable.
11266 (auto_window_vscroll_p, next_screen_context_lines)
11267 (Vscroll_preserve_screen_position): Remove leading asterisks from
11270 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
11272 Fix minor problems found by GCC 4.6.0 static checking.
11273 * buffer.c (Qclone_number): Remove for now, as it's unused.
11274 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
11275 (record_buffer): Remove unused local.
11276 * frame.c (other_visible_frames, frame_buffer_list): Now static.
11277 (set_frame_buffer_list): Remove; unused.
11278 * frame.h (other_visible_frames): Remove decl.
11279 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
11280 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
11281 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
11283 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
11284 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
11285 Define only if HAVE_GPM.
11286 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
11287 (update_hints_inhibit): Remove; never set. All uses removed.
11288 * widgetprv.h (emacsFrameClassRec): Remove decl.
11289 * window.c (delete_deletable_window): Now returns void, since it
11290 wasn't returning anything.
11291 (compare_window_configurations): Remove unused locals.
11292 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
11293 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
11294 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
11295 the same widths as pointers. This follows up on the 2011-05-06 patch.
11296 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
11297 * xterm.h: Likewise.
11298 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
11300 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
11302 * makefile.w32-in: Update dependencies.
11303 (LISP_H): Add lib/intprops.h.
11305 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
11307 * image.c (gif_load): Add animation frame delay to the metadata.
11308 (syms_of_image): Use DEFSYM. New symbol `delay'.
11310 2011-06-11 Martin Rudalics <rudalics@gmx.at>
11312 * window.c (delete_deletable_window): Re-add.
11313 (Fset_window_configuration): Rewrite to handle dead buffers and
11314 consequently deletable windows.
11315 (window_tree, Fwindow_tree): Remove. Supply functionality in
11317 (compare_window_configurations): Simplify code.
11319 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
11321 * image.c (imagemagick_load_image): Fix type mismatch.
11322 (Fimagemagick_types): Likewise.
11324 * window.h (replace_buffer_in_windows): Declare.
11326 2011-06-11 Martin Rudalics <rudalics@gmx.at>
11328 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
11329 Qclone_number. Remove external declaration of Qdelete_window.
11330 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
11332 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
11333 Run Qbuffer_list_update_hook if allowed.
11334 (Fother_buffer): Rewrite doc-string. Major rewrite for new

11787 (bidi_cache_search, bidi_cache_iterator_state)
11788 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11789 (bidi_level_of_next_char, bidi_move_to_visually_next):
11790 Support character positions inside a run of characters covered by a
11792 (bidi_paragraph_init, bidi_resolve_explicit_1)
11793 (bidi_level_of_next_char): Call bidi_fetch_char and
11794 bidi_fetch_char_advance instead of FETCH_CHAR and
11795 FETCH_CHAR_ADVANCE.
11796 (bidi_init_it): Initialize new members.
11797 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11799 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11800 instead of using explicit *_CHAR codes.
11801 (bidi_resolve_explicit, bidi_resolve_weak):
11802 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11803 bidirectional text is supported only in multibyte buffers.
11804 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11805 it to initialize the frame_window_p member of struct bidi_it.
11806 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11807 (bidi_resolve_explicit, bidi_resolve_weak)
11808 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
11809 bidi_it->nchars is non-positive.
11810 (bidi_level_of_next_char): Don't try to lookup the cache for the
11811 next/previous character if nothing is cached there yet, or if we
11812 were just reseat()'ed to a new position.
11814 * xdisp.c (set_cursor_from_row): Set start and stop points
11815 according to the row's direction when priming the loop that looks
11816 for the glyph on which to display cursor.
11817 (single_display_spec_intangible_p): Function deleted.
11818 (display_prop_intangible_p): Reimplement to call
11819 handle_display_spec instead of single_display_spec_intangible_p.
11820 Accept 3 additional arguments needed by handle_display_spec.
11821 This fixes incorrect cursor motion across display property with complex
11822 values: lists, `(when COND...)' forms, etc.
11823 (single_display_spec_string_p): Support property values that are
11824 lists with the argument STRING its top-level element.
11825 (display_prop_string_p): Fix the condition for processing a
11826 property that is a list to be consistent with handle_display_spec.
11827 (handle_display_spec): New function, refactored from the
11828 last portion of handle_display_prop.
11829 (compute_display_string_pos): Accept additional argument
11830 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11831 value of a `display' property is a "replacing spec".
11832 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11833 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11834 the display property, but just return a value indicating whether
11835 the display property will replace the characters it covers.
11836 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11837 frame_window_p members of struct bidi_it.
11838 (compute_display_string_pos, compute_display_string_end):
11840 (push_it): Accept second argument POSITION, where pop_it should
11841 jump to continue iteration.
11842 (reseat_1): Initialize bidi_it.disp_pos.
11844 * keyboard.c (adjust_point_for_property): Adjust the call to
11845 display_prop_intangible_p to its new signature.
11847 * dispextern.h (struct bidi_it): New member frame_window_p.
11848 (bidi_init_it): Update prototypes.
11849 (display_prop_intangible_p): Update prototype.
11850 (compute_display_string_pos, compute_display_string_end):
11851 Declare prototypes.
11852 (struct bidi_it): New members nchars and disp_pos. ch_len is now

11857 Malloc failure behavior now depends on size of allocation.
11858 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11859 * lisp.h: Change signatures accordingly.
11860 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11861 All callers changed. (Bug#8762)
11863 * gnutls.c: Use Emacs's memory allocators.
11864 Without this change, the gnutls library would invoke malloc etc.
11865 directly, which causes problems on non-SYNC_INPUT hosts, and which
11866 runs afoul of improving memory_full behavior. (Bug#8761)
11867 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11868 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11869 xfree instead of the default malloc, realloc, free.
11870 (Fgnutls_boot): No need to check for memory allocation failure,
11871 since xmalloc does that for us.
11873 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11874 * category.c (hash_get_category_set):
11875 * ccl.c (ccl_driver):
11876 * charset.c (Fdefine_charset_internal):

11883 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
11884 (hashfn_equal, hashfn_user_defined, make_hash_table)
11885 (maybe_resize_hash_table, hash_lookup, hash_put)
11886 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11887 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11888 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11889 * image.c (make_image, search_image_cache, lookup_image)
11890 (xpm_put_color_table_h):
11891 * lisp.h (struct Lisp_Hash_Table):
11892 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11893 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11894 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11895 * alloc.c (allocate_vectorlike):
11896 Check for overflow in vector size calculations.
11897 * ccl.c (ccl_driver):
11898 Check for overflow when converting EMACS_INT to int.
11899 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11900 need to be updated by these changes.
11901 * fns.c (make_hash_table, maybe_resize_hash_table):
11902 Check for integer overflow with large hash tables.
11903 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11904 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11905 (SXHASH_REDUCE): New macro.
11906 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11907 Use it instead of discarding useful hash info with large hash values.
11908 (sxhash_float): New function.
11909 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11910 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11911 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11912 Rewrite to use FIXNUM_BITS, as this simplifies things.
11913 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11914 Adjust signatures to match updated version of code.
11915 (consing_since_gc): Now EMACS_INT, since a single hash table can
11916 use more than INT_MAX bytes.
11918 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11920 Make it possible to build with GCC-4.6+ -O2 -flto.
11922 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11924 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11926 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11927 Call minibuffer-inactive-mode.
11929 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11931 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11932 Update dependencies.
11934 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11936 * data.c (init_data): Remove code for UTS, this system is not
11939 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11941 Don't force ./temacs to start in terminal mode.
11943 * frame.c (make_initial_frame): Initialize faces in all cases, not
11944 only when CANNOT_DUMP is defined.
11945 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11947 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11949 * dispnew.c (add_window_display_history): Use const for the string
11950 pointer. Remove declaration, not needed.
11952 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11954 Use 'inline', not 'INLINE'.
11955 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11956 * alloc.c, fontset.c (INLINE): Remove.
11957 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11958 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11959 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11960 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11961 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11963 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11965 Make it possible to run ./temacs.
11967 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11968 syms_of_callproc does the same thing. Remove test for
11969 "initialized", do it in the caller.
11970 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11972 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11974 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11975 (read_minibuf): Use get_minibuffer.
11976 (syms_of_minibuf): Use DEFSYM.
11977 (Qmetadata): New var.
11978 * data.c (Qbuffer): Don't make it static.
11979 (syms_of_data): Use DEFSYM.
11981 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11983 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11984 (CCL_CODE_MIN): New macro.
11986 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11988 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11990 * eval.c (Qdebug): Now static.
11991 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11992 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11993 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11995 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11997 * image.c: Various fixes to ImageMagick code comments.
11998 (Fimagemagick_types): Doc fix.
12000 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
12002 Minor fixes prompted by GCC 4.6.0 warnings.
12004 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12006 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12007 (x_clipboard_manager_save_all): Move extern decl to ...
12008 * xterm.h: ... here, so that it can be checked for consistency.
12010 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12012 * xselect.c (x_clipboard_manager_save_frame)
12013 (x_clipboard_manager_save_all): New functions.
12014 (Fx_clipboard_manager_save): Lisp function deleted.
12016 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12017 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12019 * xterm.h: Update prototype.
12021 2011-05-28 William Xu <william.xwl@gmail.com>
12023 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12024 exiting (Bug#8239).
12026 2011-05-28 Jim Meyering <meyering@redhat.com>
12028 Avoid a sign-extension bug in crypto_hash_function.
12029 * fns.c (to_uchar): Define.
12030 (crypto_hash_function): Use it to convert some newly-signed
12031 variables to unsigned, to avoid sign-extension bugs. For example,
12032 without this change, (md5 "truc") would evaluate to
12033 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12034 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12035 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12037 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12039 Integer overflow fixes.
12041 * dbusbind.c: Serial number integer overflow fixes.
12042 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12043 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12044 to hold a serial number that is too large for a fixnum.
12045 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12046 Check for serial numbers out of range. Decode any serial number
12047 that was so large that it became a float. (Bug#8722)
12049 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12050 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12051 Use XFASTINT rather than XUINT when numbers are nonnegative.
12052 (xd_append_arg, Fdbus_method_return_internal):
12053 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12054 arguments, check that Lisp number is nonnegative, rather than
12055 silently wrapping negative numbers around. (Bug#8722)
12056 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12059 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12061 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12063 ccl: Add integer overflow checks.
12064 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12065 (IN_INT_RANGE): New macros.
12066 (ccl_driver): Use them to check for integer overflow when
12067 decoding a CCL program. Many of the new checks are whether XINT (x)
12068 fits in int; it doesn't always, on 64-bit hosts. The new version
12069 doesn't catch all possible integer overflows, but it's an
12070 improvement. (Bug#8719)
12072 * alloc.c (make_event_array): Use XINT, not XUINT.
12073 There's no need for unsigned here.
12075 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12076 This follows up to the 2011-05-06 change that substituted uintptr_t
12077 for EMACS_INT. This case wasn't caught back then.
12079 Rework Fformat to avoid integer overflow issues.
12080 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12081 now (part of C89). Include <verify.h>.
12082 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12083 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12084 (Fformat): Avoid the prepass trying to compute sizes; it was only
12085 approximate and thus did not catch overflow reliably. Instead, walk
12086 through the format just once, formatting and computing sizes as we go,
12087 checking for integer overflow at every step, and allocating a larger
12088 buffer as needed. Keep track separately whether the format is
12089 multibyte. Keep only the most-recently calculated precision, rather
12090 than them all. Record whether each argument has been converted to
12091 string. Use EMACS_INT, not int, for byte and char and arg counts.
12092 Support field widths and precisions larger than INT_MAX. Avoid
12093 sprintf's undefined behavior with conversion specifications such as %#d
12094 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12095 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12096 formatting out-of-range floating point numbers with int
12097 formats. (Bug#8668)
12099 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12101 * data.c: Avoid integer truncation in expressions involving floats.
12102 * data.c: Include <intprops.h>.
12103 (arith_driver): When there's an integer overflow in an expression
12104 involving floating point, convert the integers to floating point
12105 so that the resulting value does not suffer from catastrophic
12106 integer truncation. For example, on a 64-bit host (* 4
12107 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12108 Do not rely on undefined behavior after integer overflow.
12110 merge count_size_as_multibyte, parse_str_to_multibyte
12111 * character.c, character.h (count_size_as_multibyte):
12112 Rename from parse_str_to_multibyte; all uses changed.
12113 Check for integer overflow.
12114 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12115 since it's now a duplicate of the other. This is more of
12116 a character than a buffer op, so better that it's in character.c.
12117 * fns.c, print.c: Adjust to above changes.
12119 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12121 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12123 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12125 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12126 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12127 (x_clipboard_manager_save): Now static.
12128 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12130 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12131 (crypto_hash_function): Now static.
12132 Fix pointer signedness problems. Avoid unnecessary initializations.
12134 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12136 * termhooks.h (Vselection_alist): Make it terminal-local.
12138 * terminal.c (create_terminal): Initialize it.
12140 * xselect.c: Support for clipboard managers.
12141 (Vselection_alist): Move to termhooks.h as terminal-local var.
12142 (LOCAL_SELECTION): New macro.
12143 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12144 (symbol_to_x_atom): Remove gratuitous arg.
12145 (x_handle_selection_request, lisp_data_to_selection_data)
12146 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12147 (x_own_selection, x_get_local_selection, x_convert_selection):
12148 New arg, specifying work frame. Use terminal-local Vselection_alist.
12149 (some_frame_on_display): Delete unused function.
12150 (Fx_own_selection_internal, Fx_get_selection_internal)
12151 (Fx_disown_selection_internal, Fx_selection_owner_p)
12152 (Fx_selection_exists_p): New optional frame arg.
12153 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12154 (x_handle_selection_clear): Don't treat other terminals with the
12155 same keyboard specially. Use the terminal-local Vselection_alist.
12156 (x_clear_frame_selections): Use Frun_hook_with_args.
12158 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12160 * xterm.h: Add support for those atoms.
12162 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12164 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12165 (converted_selections, conversion_fail_tag): New global variables.
12166 (x_selection_request_lisp_error): Free the above.
12167 (x_get_local_selection): Remove unnecessary code.
12168 (x_reply_selection_request): Args changed; handle arbitrary array
12169 of converted selections stored in converted_selections.
12170 Separate the XChangeProperty and SelectionNotify steps.
12171 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12172 (x_convert_selection): New function.
12173 (x_handle_selection_event): Simplify.
12174 (x_get_foreign_selection): Don't ignore incoming requests while
12175 waiting for an answer; this will fail when we implement
12176 SAVE_TARGETS, and seems unnecessary anyway.
12177 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12178 (Vx_sent_selection_functions): Doc fix.
12180 2011-05-26 Leo Liu <sdl.web@gmail.com>
12182 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12184 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12186 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12188 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12189 for fringe update if it has periodic bitmap.
12190 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12191 and fringe_bitmap_periodic_p.
12193 * fringe.c (get_fringe_bitmap_data): New function.
12194 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12195 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12196 row. Mark glyph row for fringe update if periodicity changed.
12198 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12199 for fringe update unless it has periodic bitmap.
12201 2011-05-25 Kenichi Handa <handa@m17n.org>
12203 * xdisp.c (get_next_display_element): Set correct it->face_id for
12204 a static composition.
12206 2011-05-24 Leo Liu <sdl.web@gmail.com>
12209 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12211 * fns.c (crypto_hash_function, Fsha1): New function.
12212 (Fmd5): Use crypto_hash_function.
12213 (syms_of_fns): Add Ssha1.
12215 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12217 * gnutls.c: Remove unused macros.
12218 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12219 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12220 Remove macros that are defined and never used.
12221 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12223 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12225 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12226 (Fx_get_selection_internal): Minor cleanup.
12227 (Fx_own_selection_internal): Rename arguments for consistency with
12230 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12232 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12234 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12236 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12238 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12240 * dispnew.c (scrolling_window): Don't exclude the case that the
12241 last enabled row in the desired matrix touches the bottom boundary.
12243 2011-05-21 Glenn Morris <rgm@gnu.org>
12245 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12246 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12247 and add some more files.
12249 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12251 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12252 report_file_error introduced by the change from 2011-05-07.
12254 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12256 * systime.h (Time): Define only if emacs is defined.
12257 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12258 where the include path doesn't have X11/X.h by default. See
12259 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12261 2011-05-20 Kenichi Handa <handa@m17n.org>
12263 * composite.c (find_automatic_composition): Fix previous change.
12265 2011-05-20 Glenn Morris <rgm@gnu.org>
12267 * lisp.mk: New file, split from Makefile.in.
12268 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12269 (shortlisp): Remove.
12270 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12272 2011-05-19 Glenn Morris <rgm@gnu.org>
12274 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12275 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12276 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12277 (lisp): Set the order to that of loadup.el.
12278 (shortlisp): Make it a copy of $lisp.
12279 (SOME_MACHINE_LISP): Remove.
12280 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12281 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12283 2011-05-18 Kenichi Handa <handa@m17n.org>
12285 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12286 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12287 (find_automatic_composition): Mostly rewrite for efficiency.
12289 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12291 * makefile.w32-in: Update dependencies.
12293 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12295 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12296 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12298 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12300 Fix some integer overflow issues, such as string length overflow.
12302 * insdel.c (count_size_as_multibyte): Check for string overflow.
12304 * character.c (lisp_string_width): Check for string overflow.
12305 Use EMACS_INT, not int, for string indexes and lengths; in
12306 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12307 the resulting string length overflows an EMACS_INT; instead,
12308 report a string overflow if no precision given. When checking for
12309 precision exhaustion, use a check that cannot possibly have
12310 integer overflow. (Bug#8675)
12311 * character.h (lisp_string_width): Adjust to new signature.
12313 * alloc.c (string_overflow): New function.
12314 (Fmake_string): Use it. This doesn't change behavior, but saves
12315 a few bytes and will simplify future changes.
12316 * character.c (string_escape_byte8): Likewise.
12317 * lisp.h (string_overflow): New decl.
12319 Fixups, following up to the user-interface timestamp change.
12320 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12321 for UI timestamps, instead of unsigned long.
12322 * msdos.c (mouse_get_pos): Likewise.
12323 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12324 * w32gui.h (Time): Define by including "systime.h" rather than by
12325 declaring it ourselves. (Bug#8664)
12327 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12328 * image.c (clear_image_cache): Likewise.
12330 * term.c (term_mouse_position): Don't assume time_t wraparound.
12332 Be more systematic about user-interface timestamps.
12333 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12334 and sometimes 'EMACS_UINT', to represent these timestamps.
12335 This change causes it to use 'Time' uniformly, as that's what X uses.
12336 This makes the code easier to follow, and makes it easier to catch
12337 integer overflow bugs such as Bug#8664.
12338 * frame.c (Fmouse_position, Fmouse_pixel_position):
12339 Use Time, not unsigned long, for user-interface timestamps.
12340 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12341 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12342 * keyboard.h (last_event_timestamp): Likewise.
12343 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12344 * menu.h (xmenu_show): Likewise.
12345 * term.c (term_mouse_position): Likewise.
12346 * termhooks.h (struct input_event.timestamp): Likewise.
12347 (struct terminal.mouse_position_hook): Likewise.
12348 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12349 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12350 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12351 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12352 what it was before.
12353 * menu.h, termhooks.h: Include "systime.h", for Time.
12355 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12356 Don't assume that the difference between two unsigned long values
12357 can fit into an integer. At this point, we know button_down_time
12358 <= event->timestamp, so the difference must be nonnegative, so
12359 there's no need to cast the result if double-click-time is
12360 nonnegative, as it should be; check that it's nonnegative, just in
12361 case. This bug is triggered when events are more than 2**31 ms
12362 apart (about 25 days). (Bug#8664)
12364 * xselect.c (last_event_timestamp): Remove duplicate decl.
12365 (x_own_selection): Remove needless cast to unsigned long.
12367 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12368 that always fit in int. Use a sentinel instead of a counter, to
12369 avoid a temp and to allay GCC's concerns about possible int overflow.
12370 * frame.h (struct frame): Use int for menu_bar_items_used
12371 instead of EMACS_INT, since it always fits in int.
12373 * menu.c (grow_menu_items): Check for int overflow.
12375 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12377 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12378 Before, the code was not consistent. These values cannot exceed
12379 2**31 - 1 so there's no need to make them unsigned.
12380 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12381 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12382 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12384 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12386 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12387 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12388 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12389 presumably because the widths might not match.
12391 * window.c (size_window): Avoid needless test at loop start.
12393 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12395 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12397 2011-05-12 Drew Adams <drew.adams@oracle.com>
12399 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12401 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12403 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12404 `width' to `bar_area_x' and `bar_area_width', respectively.
12405 (x_scroll_run): Take account of fringe background extension.
12407 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12408 Rename local vars `left' and `width' to `bar_area_x' and
12409 `bar_area_width', respectively.
12410 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12411 background extension.
12413 2011-05-10 Jim Meyering <meyering@redhat.com>
12415 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12417 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12419 * image.c (Finit_image_library): Return t for built-in image types,
12420 like pbm and xbm. (Bug#8640)
12422 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12424 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12426 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12428 * w32console.c (Fset_screen_color): Doc fix.
12429 (Fget_screen_color): New function.
12430 (syms_of_ntterm): Defsubr it.
12432 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12433 unlink the temporary file if Fcall_process didn't create it in the
12435 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12436 child process will be redirected to a file specified with `:file'.
12437 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12438 cue to call_process_cleanup not to close that handle.
12440 2011-05-07 Ben Key <bkey76@gmail.com>
12442 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12443 one of two shell specific rules, either bootstrap-temacs-CMD or
12444 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12445 to the previous implementation of the bootstrap-temacs rule.
12446 The bootstrap-temacs-CMD rule is similar to the previous
12447 implementation of the bootstrap-temacs rule except that it
12448 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12451 These changes, along with some changes to nt/configure.bat,
12452 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12453 earlier fix to add support for --cflags and --ldflags options
12454 that include quotes so that it works whether make uses cmd or
12457 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12459 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12460 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12462 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12463 a string. Handle both cases.
12464 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12465 (Fdbus_register_method): Use Qinvalid_function.
12467 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12469 * makefile.w32-in: Update dependencies.
12470 (LISP_H): Add inttypes.h and stdin.h.
12471 (PROCESS_H): Add unistd.h.
12473 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12475 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12476 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12478 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12480 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12482 * term.c (vfatal): Remove stray call to va_end.
12483 It's not needed and the C Standard doesn't allow it here anyway.
12485 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12486 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12488 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12491 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12493 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12495 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12497 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12499 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12501 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12502 * charset.c (Fdefine_charset_internal): Don't initialize
12503 charset.code_space[15]. The value was garbage, on hosts with
12504 32-bit int (Bug#8600).
12506 * lread.c (read_integer): Be more consistent with string-to-number.
12507 Use string_to_number to do the actual conversion; this avoids
12508 rounding errors and fixes some other screwups. Without this fix,
12509 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12510 (digit_to_number): Move earlier, for benefit of read_integer.
12511 Return -1 if the digit is out of range for the base, -2 if it is
12512 not a digit in any supported base. (Bug#8602)
12514 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12516 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12517 to match comment at start of function. This also removes a
12518 GCC warning about overflow in a 32+64-bit port.
12520 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12522 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12523 Reported by Stefan Monnier in
12524 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12525 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12526 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12528 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12529 (EMACS_UINTPTR): Likewise, with uintptr_t.
12531 * lisp.h: Prefer 64-bit EMACS_INT if available.
12532 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12533 on 32-bit hosts that have 64-bit int, so that they can access
12535 However, temporarily disable this change unless the temporary
12536 symbol WIDE_EMACS_INT is defined.
12538 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12540 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12541 This removes an assumption that EMACS_INT and long are the same
12542 width as pointers. The assumption is true for Emacs porting targets
12543 now, but we want to make other targets possible.
12544 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12545 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12546 In the rest of the code, change types of integers that hold casted
12547 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12548 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12549 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12550 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12551 No need to cast type when ORing.
12552 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12553 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12554 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12555 assume EMACS_INT is the same width as char *.
12556 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12557 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12558 Remove no-longer-needed casts.
12559 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12560 (xg_tool_bar_help_callback, xg_make_tool_item):
12561 Use EMACS_INTPTR to hold an integer
12562 that will be cast to void *; this can avoid a GCC warning
12563 if EMACS_INT is not the same width as void *.
12564 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12565 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12566 (current_message_1, set_message_1):
12567 Use a local to convert to proper width without a cast.
12568 * xmenu.c (dialog_selection_callback): Likewise.
12570 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12571 Also, don't assume VALBITS / RAND_BITS is less than 5,
12572 and don't rely on undefined behavior when shifting a 1 left into
12574 * lisp.h (get_random): Change signature to match.
12576 * lread.c (hash_string): Use size_t, not int, for hash computation.
12577 Normally we prefer signed values; but hashing is special, because
12578 it's better to use unsigned division on hash table sizes so that
12579 the remainder is nonnegative. Also, size_t is the natural width
12580 for hashing into memory. The previous code used 'int', which doesn't
12581 retain enough info to hash well into very large tables.
12582 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12584 * dbusbind.c: Don't possibly lose pointer info when converting.
12585 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12586 Use XPNTR rather than XHASH, so that the high-order bits of
12587 the pointer aren't lost when converting through void *.
12589 * eval.c (Fautoload): Don't double-shift a pointer.
12591 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12593 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12595 * gnutls.c (DEF_GNUTLS_FN):
12596 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12598 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12600 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12603 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12605 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12606 New version that can reserve upto 2GB of heap space.
12608 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12610 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12612 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12614 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12615 `gnutls_certificate_set_x509_key_file'.
12617 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12619 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12620 Update dependencies.
12622 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12624 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12625 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12626 Remove unused parameter `fildes'.
12627 * process.c (read_process_output, send_process): Don't pass it.
12629 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12631 Fix previous change: the library cache is defined in w32.c.
12632 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12633 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12635 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12637 Implement dynamic loading of GnuTLS on Windows.

12674 * process.c: Include lisp.h before w32.h, not after.
12675 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12676 instead of gnutls_record_check_pending.

12680 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12682 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

12728 rather than `XVECTOR (FOO)->size'.
12730 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12731 inttypes.h, as a gnulib replacement is used if it not available in

12759 produced by %s or %c overflows available buffer space. (Bug#8545)
12761 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12763 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

12766 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12768 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12770 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12772 * keyboard.c (Qdelayed_warnings_hook): Define.
12773 (command_loop_1): Run `delayed-warnings-hook'
12774 if Vdelayed_warnings_list is non-nil.
12775 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12776 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.

12780 * doprnt.c (doprnt): Don't return value smaller than the buffer
12781 size if the message was truncated. (Bug#8545).

12785 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

12792 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12794 * makefile.w32-in: Update dependencies.
12796 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12798 Improve `doprnt' and its usage. (Bug#8545)
12799 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12800 `format_end'. Remove support for %l as a conversion specifier.
12801 Don't use xrealloc. Improve diagnostics when the %l size modifier
12802 is used. Update the commentary.
12804 * eval.c (verror): Simplify calculation of size_t.
12806 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12809 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12811 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12814 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12816 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12817 This makes this file independent of the recent pseudovector change.
12819 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12821 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12823 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12824 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12825 Remove unused local.
12826 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12828 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12829 GCC 4.6.0 optimizes based on type-based alias analysis.
12830 For example, if b is of type struct buffer * and v of type struct
12831 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12832 != &v->size, and therefore "v->size = 1; b->size = 2; return
12833 v->size;" must therefore return 1. This assumption is incorrect
12834 for Emacs, since it type-puns struct Lisp_Vector * with many other
12835 types. To fix this problem, this patch adds a new type struct
12836 vectorlike_header that documents the constraints on layout of vectors
12837 and pseudovectors, and helps optimizing compilers not get fooled
12838 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12839 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12840 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12842 (XSETPVECTYPE): Rewrite in terms of new macro.
12843 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12844 This is a bit clearer, and further avoids the possibility of
12845 undesirable aliasing.
12846 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12847 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12848 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12849 since Lisp_Subr is a special case (no "next" field).
12850 (ASIZE): Now uses header.size rather than size.
12851 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12852 to avoid the hassle of writing XVECTOR (foo)->header.size.
12853 (struct vectorlike_header): New type.
12854 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12855 object, to help avoid aliasing.
12856 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12857 (SUBRP): Likewise, since Lisp_Subr is a special case.
12858 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12859 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12860 (struct Lisp_Hash_Table): Combine first two members into a single
12861 struct vectorlike_header member. All uses of "size" and "next" members
12862 changed to be "header.size" and "header.next".
12863 * buffer.h (struct buffer): Likewise.
12864 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12865 * frame.h (struct frame): Likewise.
12866 * process.h (struct Lisp_Process): Likewise.
12867 * termhooks.h (struct terminal): Likewise.
12868 * window.c (struct save_window_data, struct saved_window): Likewise.
12869 * window.h (struct window): Likewise.
12870 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12871 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12872 * buffer.c (init_buffer_once): Likewise.
12873 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12875 * process.c (Fformat_network_address): Use local var for size,
12878 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12880 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12881 * data.c (atof): Remove decl; no longer used or needed.
12882 (digit_to_number): Move to lread.c.
12883 (Fstring_to_number): Use new string_to_number function, to be
12884 consistent with how the Lisp reader treats infinities and NaNs.
12885 Do not assume that floating-point numbers represent EMACS_INT
12886 without losing information; this is not true on most 64-bit hosts.
12887 Avoid double-rounding errors, by insisting on integers when
12888 parsing non-base-10 numbers, as the documentation specifies.
12889 * lisp.h (string_to_number): New decl, replacing ...
12890 (isfloat_string): Remove.
12891 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12892 (read1): Do not accept +. and -. as integers; this
12893 appears to have been a coding error. Similarly, do not accept
12894 strings like +-1e0 as floating point numbers. Do not report
12895 overflow for integer overflows unless the base is not 10 which
12896 means we have no simple and reliable way to continue.
12897 Break out the floating-point parsing into a new
12898 function string_to_number, so that Fstring_to_number parses
12899 floating point numbers consistently with the Lisp reader.
12900 (digit_to_number): Move here from data.c. Make it static inline.
12901 (E_CHAR, EXP_INT): Remove, replacing with ...
12902 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12903 (string_to_number): New function, replacing isfloat_string.
12904 This function checks for valid syntax and produces the resulting
12905 Lisp float number too. Rework it so that string-to-number
12906 no longer mishandles examples like "1.0e+". Use strtoumax,
12907 so that overflow for non-base-10 numbers is reported only when
12908 there's no portable and simple way to convert to floating point.
12910 * textprop.c (set_text_properties_1): Rewrite for clarity,
12911 and to avoid GCC warning about integer overflow.
12913 * intervals.h (struct interval): Use EMACS_INT for members
12914 where EMACS_UINT might cause problems. See
12915 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12916 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12917 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12919 (offset_intervals): Tell GCC not to worry about length overflow
12920 when negating a negative length.
12922 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12923 (overrun_check_free): Likewise.
12925 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12926 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12929 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12930 (gnutls_make_error): Rename local to avoid shadowing.
12931 (gnutls_emacs_global_deinit): ifdef out; not used.
12932 (Fgnutls_boot): Use const for pointer to readonly storage.
12933 Comment out unused local. Fix pointer signedness problems.
12935 * lread.c (openp): Don't stuff size_t into an 'int'.
12936 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12937 about possible signed overflow.
12939 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12940 (GDK_KEY_g): Don't define if already defined.
12941 (xg_prepare_tooltip): Avoid pointer signedness problem.
12942 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12944 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12945 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12947 * xfns.c (Fx_window_property): Simplify a bit,
12948 to make a bit faster and to avoid GCC 4.6.0 warning.
12949 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12951 * fns.c (internal_equal): Don't assume size_t fits in int.
12953 * alloc.c (compact_small_strings): Tighten assertion a little.
12955 Replace pEd with more-general pI, and fix some printf arg casts.
12956 * lisp.h (pI): New macro, generalizing old pEd macro to other
12957 conversion specifiers. For example, use "...%"pI"d..." rather
12958 than "...%"pEd"...".
12959 (pEd): Remove. All uses replaced with similar uses of pI.
12960 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12961 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12962 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12963 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12964 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12965 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12966 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12968 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12969 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12970 * print.c (safe_debug_print, print_object): Likewise.
12971 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12973 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12974 avoiding the 0 flag, which is not portable.
12975 * process.c (Fmake_network_process): Use pI to avoid cast.
12976 * region-cache.c (pp_cache): Likewise.
12977 * xdisp.c (decode_mode_spec): Likewise.
12978 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12979 behavior on 64-bit hosts with printf arg.
12980 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12981 (x_stop_queuing_selection_requests): Likewise.
12982 (x_get_window_property): Don't truncate byte count to an 'int'
12985 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12986 here, since it parses constructs like leading '-' and spaces,
12987 which are not wanted; and it overflows with large numbers.
12988 Instead, simply match F[0-9]+, which is what is wanted anyway.
12990 * alloc.c: Remove unportable assumptions about struct layout.
12991 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12992 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12993 (allocate_vectorlike, make_pure_vector): Use the new macros,
12994 plus offsetof, to remove unportable assumptions about struct layout.
12995 These assumptions hold on all porting targets that I know of, but
12996 they are not guaranteed, they're easy to remove, and removing them
12997 makes further changes easier.
12999 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
13000 This doesn't fix a bug but makes the code clearer.
13001 (string_overrun_cookie): Now const. Use initializers that
13002 don't formally overflow signed char, to avoid warnings.
13003 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
13004 can cause Emacs to crash when string overrun checking is enabled.
13005 (allocate_buffer): Don't assume sizeof (struct buffer) is a
13006 multiple of sizeof (EMACS_INT); it need not be, if
13007 alignof(EMACS_INT) < sizeof (EMACS_INT).
13008 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
13010 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
13012 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
13014 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
13016 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
13017 supposed to be handshaking. (Bug#8556)
13018 Reported by Paul Eggert <eggert@cs.ucla.edu>.
13020 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
13022 * lisp.h (Qdebug): List symbol.
13023 * eval.c (Qdebug): Restore global linkage.
13024 * keyboard.c (debug-on-event): New variable.
13025 (handle_user_signal): Break into debugger when debug-on-event
13026 matches the current signal symbol.
13028 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
13030 * alloc.c (check_sblock, check_string_bytes)
13031 (check_string_free_list): Convert to standard C.
13033 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
13035 * w32.c (emacs_gnutls_push): Fix typo.
13037 2011-04-25 Eli Zaretskii <eliz@gnu.org>
13039 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
13040 "cast to pointer from integer of different size".
13042 Improve doprnt and its use in verror. (Bug#8545)
13043 * doprnt.c (doprnt): Document the set of format control sequences
13044 supported by the function. Use SAFE_ALLOCA instead of always
13047 * eval.c (verror): Don't limit the buffer size at size_max-1, that
13048 is one byte too soon. Don't use xrealloc; instead xfree and
13051 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
13053 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
13056 * gnutls.c: Renamed global_initialized to
13057 gnutls_global_initialized. Added internals for the
13058 :verify-hostname-error, :verify-error, and :verify-flags
13059 parameters of `gnutls-boot' and documented those parameters in the

13543 * xdisp.c (redisplay_window): Simplify code, to make it more
13544 obvious that ignore_mouse_drag_p is not accessed if !defined
13545 USE_GTK && !defined HAVE_NS.
13547 * intervals.c: Make symbols static if they're not exported.

13550 * intervals.h (merge_interval_right, delete_interval): Remove decls.
13552 * insdel.c: Make symbols static if they're not exported.
13553 However, leave prepare_to_modify_buffer alone. It's never
13554 called from outside this function, but that appears to be a bug.
13555 (combine_after_change_list, combine_after_change_buffer):
13556 (adjust_after_replace, signal_before_change): Now static.
13557 (adjust_after_replace_noundo): Remove; unused.

13585 * font.c (font_close_object): Now static.
13586 * font.h (font_close_object): Remove.
13587 * fontset.c (FONTSET_OBJLIST): Remove.
13588 (free_realized_fontset) #if-0 the body, which does nothing.
13589 (face_suitable_for_char_p): #if-0, as it's never called.
13590 * fontset.h (face_suitable_for_char_p): Remove decl.
13591 * xfaces.c (face_at_string_position):
13592 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
13593 since 0 is always ASCII.
13595 * fns.c (weak_hash_tables): Now static.
13597 * fileio.c: Make symbols static if they're not exported.

13616 * editfns.c, lisp.h (get_operating_system_release): Remove.
13617 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
13618 worth the hassle of breaking this out.
13620 * xterm.c: Make symbols static if they're not exported.
13621 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

13724 * buffer.c (buffer_count): Remove unused var.

13728 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13729 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13730 exported only to the debugger.

13733 * atimer.h (run_all_atimers): Remove; not exported.
13735 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13736 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13737 was inaccessible from Lisp.
13738 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13739 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13741 alloc.c: Import and export fewer symbols, and remove unused items.
13742 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13744 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13745 it's not optimized away by whole-program optimization.
13746 (message_enable_multibyte, free_misc): Remove.
13747 (catchlist, handlerlist, mark_backtrace):
13748 Declare only if BYTE_MARK_STACK.

13757 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13758 (mark_backtrace): Define only if BYTE_MARK_STACK.
13759 * xdisp.c (message_enable_multibyte): Now static.
13761 Declare Lisp_Object Q* variables to be 'static' if not exported.
13762 This makes it easier for human readers (and static analyzers)
13763 to see whether these variables are used from other modules.
13764 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13765 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

13774 Remove decls of unexported vars.
13775 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13777 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13779 Make Emacs functions such as Fatom 'static' by default.
13780 This makes it easier for human readers (and static analyzers)
13781 to see whether these functions can be called from other modules.
13782 DEFUN now defines a static function. To make the function external
13783 so that it can be used in other C modules, use the new macro DEFUE.
13784 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13785 (Finit_image_library):
13786 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13787 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13788 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13789 Remove decls, since these functions are now static.
13790 (Funintern, Fget_internal_run_time): New decls, since these functions
13791 were already external.
13793 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13794 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

13800 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13801 Mark functions with DEFUE instead of DEFUN,
13802 if they are used in other modules.
13803 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13804 decls for now-static functions.
13805 * buffer.h (Fdelete_overlay): Remove decl.
13806 * callproc.c (Fgetenv_internal): Mark as internal.
13807 * composite.c (Fremove_list_of_text_properties): Remove decl.

13814 * fileio.c (Fmake_symbolic_link): New forward static decl.
13815 * image.c (Finit_image_library): New forward static decl.
13816 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13817 * intervals.h (Fprevious_property_change):
13818 (Fremove_list_of_text_properties): Remove decls.
13819 * keyboard.c (Fthis_command_keys): Remove decl.
13820 (Fcommand_execute): New forward static decl.

13836 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13838 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13841 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13843 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13844 when at ZV. (Bug#8487)
13846 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13848 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13850 * keyboard.c (parse_tool_bar_item): Likewise.
13851 * sound.c (sound_cleanup, alsa_close): Likewise.
13852 * termcap.c (tgetent): Likewise.
13853 * xfns.c (x_default_font_parameter): Likewise.
13854 * xsettings.c (read_and_apply_settings): Likewise.
13856 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13857 (overrun_check_free): Protoize.
13859 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13861 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13862 since callers should never pass a negative size.
13863 Change the signature to match that of plain 'read' and 'write'; see
13864 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13865 * lisp.h: Update prototypes of emacs_write and emacs_read.
13867 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13869 * xdisp.c (redisplay_window): Don't try to determine the character
13870 position of the scroll margin if the window start point w->startp
13871 is outside the buffer's accessible region. (Bug#8468)
13873 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13875 Fix write-region and its subroutines for buffers > 2GB.
13876 * fileio.c (a_write, e_write): Modify declaration of arguments and
13877 local variables to support buffers larger than 2GB.
13878 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13880 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13881 argument, local variables, and return value.
13883 * lisp.h: Update prototypes of emacs_write and emacs_read.
13885 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13887 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13889 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13891 Fix more problems found by GCC 4.6.0's static checks.
13893 * xdisp.c (vmessage): Use a better test for character truncation.
13895 * charset.c (load_charset_map): <, not <=, for optimization,
13896 and to avoid potential problems with integer overflow.
13897 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13898 * casetab.c (set_identity, shuffle): Likewise.
13899 * editfns.c (Fformat): Likewise.
13900 * syntax.c (skip_chars): Likewise.
13902 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13903 This also lets GCC 4.6.0 generate slightly better loop code.
13905 * callint.c (Fcall_interactively): <, not <=, for optimization.
13906 (Fcall_interactively): Count the number of arguments produced,
13907 not the number of arguments given. This is simpler and lets GCC
13908 4.6.0 generate slightly better code.
13910 * ftfont.c: Distingish more carefully between FcChar8 and char.
13911 The previous code passed unsigned char * to a functions like
13912 strlen and xstrcasecmp that expect char *, which does not
13913 conform to the C standard.
13914 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13915 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13916 char * when the C standard requires it.
13918 * keyboard.c (read_char): Remove unused var.
13920 * eval.c: Port to Windows vsnprintf (Bug#8435).
13921 Include <limits.h>.
13922 (SIZE_MAX): Define if the headers do not.
13923 (verror): Do not give up if vsnprintf returns a negative count.
13924 Instead, grow the buffer. This ports to Windows vsnprintf, which
13925 does not conform to C99. Problem reported by Eli Zaretskii.
13926 Also, simplify the allocation scheme, by avoiding the need for
13927 calling realloc, and removing the ALLOCATED variable.
13929 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13931 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13932 But keep the doprint source code for now, as we might revamp it
13933 and use it again (Bug#8435).
13934 * lisp.h (doprnt): Remove.
13935 * Makefile.in (base_obj): Remove doprnt.o.
13936 * deps.mk (doprnt.o): Remove.
13938 error: Print 32- and 64-bit integers portably (Bug#8435).
13939 Without this change, on typical 64-bit hosts error ("...%d...", N)
13940 was used to print both 32- and 64-bit integers N, which relied on
13941 undefined behavior.
13942 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13943 * lisp.h (error, verror): Mark as printf-like functions.
13944 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.

14094 This avoids several warnings with gcc -Wstrict-overflow.
14095 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14096 directly, rather than having caller test rule sign. This avoids
14097 some unnecessary tests.
14098 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14099 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14100 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14102 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14103 (xfont_open): Avoid unnecessary tests.
14105 * composite.c (composition_gstring_put_cache): Use unsigned integer.

14117 since the condition is always true at first.
14119 * intervals.c (graft_intervals_into_buffer): Mark var as used.

14150 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14152 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14153 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14154 can always succeed if overflow has undefined behavior.
14156 * search.c (boyer_moore, wordify): Remove vars set but not used.
14157 (wordify): Omit three unnecessary tests.
14159 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

14171 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14172 Check for integer overflow on size calculations.
14174 * buffer.c (Fprevious_overlay_change): Remove var that is set
14177 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14178 Remove vars that are set but not used.
14179 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.

14187 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14188 that are set but not used.
14190 * xfns.c (make_invisible_cursor): Don't return garbage
14191 if XCreateBitmapFromData fails (Bug#8410).
14193 * xselect.c (x_get_local_selection, x_handle_property_notify):
14194 Remove vars that are set but not used.
14196 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
14197 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

14200 Remove var that is set but not used.
14201 (scroll_bar_windows_size): Now size_t, not int.
14202 (x_send_scroll_bar_event): Use size_t, not int, for sizes.

14218 that is set but not used.
14220 * print.c (print_object): Remove var that is set but not used.
14222 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14223 The gnulib version avoids calling malloc in the usual case,
14224 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14225 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14226 * filelock.c (current_lock_owner): Likewise.
14227 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14228 * sysdep.c: Include allocator.h, careadlinkat.h.
14229 (emacs_no_realloc_allocator): New static constant.
14230 (emacs_readlink): New function.
14231 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14232 ../lib/careadlinkat.h.
14234 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14236 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14237 first non-nil return value).

14253 (get_per_char_metric): Remove parameter `f', unused since
14254 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

14298 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
14299 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
14300 (FletX, Flet): Obey lexical binding.
14301 (Fcommandp): Handle closures.
14302 (Feval): New `lexical' arg.
14303 (eval_sub): New function extracted from Feval. Use it almost
14304 everywhere where Feval was used. Look up vars in lexical env.
14306 (Ffunctionp): Move from subr.el.
14307 (Ffuncall): Handle closures.
14308 (apply_lambda): Remove `eval_flags'.
14309 (funcall_lambda): Handle closures and new byte-code-functions.
14310 (Fspecial_variable_p): New function.
14311 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14312 but without exporting it to Lisp.
14314 * doc.c (Fdocumentation, store_function_docstring):
14315 * data.c (Finteractive_form): Handle closures.
14317 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14320 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14322 (exec_byte_code): New function extracted from Fbyte_code to handle new
14323 calling convention for byte-code-functions. Add new byte-codes.

14337 Limit scrolling to 100 screen lines.
14338 (redisplay_window): Even when falling back on "recentering",
14339 position point in the window according to scroll-conservatively,
14340 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14342 (try_scrolling): When point is above the window, allow searching
14343 as far as scroll_max, or one screenful, to compute vertical
14344 distance from PT to the scroll margin position. This prevents
14345 try_scrolling from unnecessarily failing when
14346 scroll-conservatively is set to a value slightly larger than the
14347 window height. Clean up the case of PT below the margin at bottom
14348 of window: scroll_max can no longer be INT_MAX. When aggressive
14349 scrolling is in use, don't let point enter the opposite scroll
14350 margin as result of the scroll.
14351 (syms_of_xdisp) <scroll-conservatively>: Document the
14352 threshold of 100 lines for never-recentering scrolling.

14361 (redisplay_internal): Remove parameter `preserve_echo_area',
14362 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14364 * indent.c (Fvertical_motion):
14365 * window.c (window_scroll_pixel_based, Frecenter):
14366 Don't pass `need_y_p' to `move_it_by_lines'.

14405 instead of alloca (Bug#8344).
14407 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14408 (Fbacktrace_frame): Don't assume nframes fits in int.
14410 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14412 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14415 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14417 * cm.c (calccost): Turn while-do into do-while, for clarity.
14419 * keyboard.c (syms_of_keyboard): Use the same style as later
14420 in this function when indexing through an array. This also
14421 works around GCC bug 48267.
14423 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14425 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

14428 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14430 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14431 This avoids undefined behavior on integer overflow, and is a bit
14432 more convenient anyway since it is compared to a size_t variable.
14434 Variadic C functions now count arguments with size_t, not int.
14435 This avoids an unnecessary limitation on 64-bit machines, which
14436 caused (substring ...) to crash on large vectors (Bug#8344).
14437 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14438 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14439 All variadic functions and their callers changed accordingly.
14440 (struct gcpro.nvars): Now size_t, not int. All uses changed.

14442 * editfns.c (general_insert_function): Likewise.
14443 * eval.c (struct backtrace.nargs, interactive_p)
14444 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14445 (funcall_lambda, mark_backtrace): Likewise.
14446 * fns.c (concat): Likewise.
14447 * frame.c (x_set_frame_parameters): Likewise.
14448 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14449 0 if not found, not -1. All callers changed.
14451 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14452 (stack_copy_size): Now size_t, not int.
14453 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

14459 All callers changed.
14461 * lisp.h (multibyte_char_to_unibyte):
14462 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14463 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

14468 * search.c (Freplace_match):
14469 * xdisp.c (message_dolog, set_message_1): All callers changed.
14471 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14473 * keyboard.c (safe_run_hook_funcall): New function.
14474 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14475 don't set the hook to nil, but remove the offending function instead.
14476 (Qcommand_hook_internal): Remove, unused.
14477 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14478 Vcommand_hook_internal.
14480 * eval.c (enum run_hooks_condition): Remove.
14481 (funcall_nil, funcall_not): New functions.
14482 (run_hook_with_args): Call each function through a `funcall' argument.
14483 Remove `cond' argument, now redundant.
14484 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14485 (Frun_hook_with_args_until_failure): Adjust accordingly.
14486 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

14490 * dispextern.h (string_buffer_position): Remove declaration.
14492 * print.c (strout): Remove parameter `multibyte', unused since
14493 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14495 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14496 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14497 All callers changed.
14499 * w32.c (_wsa_errlist): Use braces for struct initializers.
14501 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14502 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14503 All callers changed.

14505 used outside xdisp.c).
14506 (cursor_row_p): Remove parameter `w', unused since
14507 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14509 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14510 All callers changed.
14512 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14514 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

14525 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14527 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

14540 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14542 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14543 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14545 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14547 * w32.c (read_unc_volume): Use parameter `henum', instead of
14548 global variable `wget_enum_handle'.
14550 * keymap.c (describe_vector): Remove parameters `indices' and
14551 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14566 * gtkutil.c (xg_maybe_add_timer):
14567 * keyboard.c (readable_events):
14568 * process.c (wait_reading_process_output):
14569 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14571 * insdel.c (adjust_markers_gap_motion):
14572 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

14646 2011-03-23 Julien Danjou <julien@danjou.info>
14648 * term.c (Fsuspend_tty, Fresume_tty):
14649 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14650 * window.c (temp_output_buffer_show):

14657 * callint.c (Fcall_interactively):
14658 * buffer.c (Fkill_all_local_variables):
14659 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14661 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14662 unconditionally since it does the check itself.
14664 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14666 Fix more problems found by GCC 4.5.2's static checks.
14668 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14669 the first time through the loop, since we know p0 < p1 then.
14670 This also avoids a gcc -Wstrict-overflow warning.
14672 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14673 leading to a memory leak, possible in functions like
14674 load_charset_map_from_file that can allocate an unbounded number
14675 of objects (Bug#8318).
14677 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14678 that could (at least in theory) be that large.
14680 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14681 This is less likely to overflow, and avoids undefined behavior if
14682 overflow does occur. All callers changed. Use strtoul to scan
14683 for the unsigned long integer.
14684 (pint2hrstr): Simplify and tune code slightly.
14685 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14687 * scroll.c (do_scrolling): Work around GCC bug 48228.
14688 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

14695 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14698 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14700 * process.c (Fmake_network_process): Use socklen_t, not int,
14701 where POSIX says socklen_t is required in portable programs.
14702 This fixes a porting bug on hosts like 64-bit HP-UX, where
14703 socklen_t is wider than int (Bug#8277).
14704 (Fmake_network_process, server_accept_connection):
14705 (wait_reading_process_output, read_process_output):
14708 * process.c: Rename or move locals to avoid shadowing.

14715 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14716 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14718 Make tparam.h and terminfo.c consistent.
14719 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14720 Include tparam.h instead, since it declares them.
14721 * cm.h (PC): Remove extern decl; tparam.h now does this.
14722 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14723 * terminfo.c: Include tparam.h, to check interfaces.
14724 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14725 (tparam): Adjust signature to match interface in tparam.h;
14726 this removes some undefined behavior. Check that outstring and len
14727 are zero, which they always are with Emacs.
14728 * tparam.h (PC, BC, UP): New extern decls.
14730 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14731 (xftfont_open): Rename locals to avoid shadowing.
14733 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14734 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14735 (OTF_TAG_SYM): Omit macro if not needed.
14736 (ftfont_list): Remove unused local.
14737 (get_adstyle_property, ftfont_pattern_entity):
14738 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
14739 Rename locals to avoid shadowing.
14741 * xfont.c (xfont_list_family): Mark var as initialized.
14743 * xml.c (make_dom): Now static.
14745 * composite.c (composition_compute_stop_pos): Rename local to
14747 (composition_reseat_it): Remove unused locals.
14748 (find_automatic_composition, composition_adjust_point): Likewise.
14749 (composition_update_it): Mark var as initialized.
14750 (find_automatic_composition): Mark vars as initialized,
14751 with a FIXME (Bug#8290).
14753 character.h: Rename locals to avoid shadowing.
14754 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14755 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14756 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14757 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14758 to avoid shadowing.
14760 * textprop.c (property_change_between_p): Remove; unused.
14762 * intervals.c (interval_start_pos): Now static.
14764 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
14766 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
14767 Rename locals to avoid shadowing.
14769 * sound.c (wav_play, au_play, Fplay_sound_internal):
14770 Fix pointer signedness.
14771 (alsa_choose_format): Remove unused local var.
14772 (wav_play): Initialize a variable to 0, to prevent undefined
14773 behavior (Bug#8278).
14775 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14777 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14779 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14780 clobbering (Bug#8298).
14781 * sysdep.c (sys_subshell): Likewise.
14782 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14784 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14785 This should get cleaned up, so that child_setup has the
14786 same signature on all platforms.
14788 * callproc.c (call_process_cleanup): Now static.
14789 (relocate_fd): Rename locals to avoid shadowing.
14791 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14793 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14794 not to be necessary, and produces flickering.
14796 2011-03-20 Glenn Morris <rgm@gnu.org>
14798 * config.in: Remove file.
14800 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14802 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14803 are now in src/globals.h.
14804 (syms_of_minibuf): Remove spurious & from previous change.

14821 2011-03-17 Eli Zaretskii <eliz@gnu.org>
14823 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

14830 (sigchld_handler): Now static.
14832 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14833 That way, the code declares only the vars that it needs.
14834 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
14835 * s/cygwin.h (PTY_ITERATION): Likewise.
14836 * s/darwin.h (PTY_ITERATION): Likewise.

14839 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
14840 * process.c (allocate_pty): Don't declare stb unless it's needed.
14842 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
14843 (CONSTANTLIM): Remove; unused.
14844 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14845 Define only if needed.
14847 * unexelf.c (unexec): Name an expression,

14918 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
14919 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14920 some of which prompt warnings from gcc -Wbad-function-cast.
14921 (Fformat_time_string, Fencode_time, Finsert_char):
14922 (Ftranslate_region_internal, Fformat):

14950 (Fmemory_limit): Cast sbrk's returned value to char *.
14952 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14955 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14957 Use functions, not macros, for up- and down-casing (Bug#8254).
14958 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14959 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14960 to use the following functions instead of these macros.
14961 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14962 EMACS_INT, since callers assume the returned value fits in int.
14963 (upcase1): Likewise, for UPCASE_TABLE.
14964 (uppercasep, lowercasep, upcase): New static inline functions.
14965 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14975 (regex_compile, re_match_2_internal): Mark locals as initialized.
14976 (RETALLOC_IF): Define only if needed.
14977 (WORDCHAR_P): Likewise. This one is never needed, but is used
14978 only in a comment talking about a compiler bug, so put inside
14979 the #if 0 of that comment.
14980 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14981 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

15007 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
15008 New macros, so that the caller can use some names other than
15009 gcpro1, gcpro2, etc.
15010 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15012 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15013 argument, for consistency with GCPRO2_VAR, etc: it is now the
15014 prefix of the variable, not the variable itself. All uses
15016 * dired.c (directory_files_internal, file_name_completion):
15017 Rename locals to avoid shadowing.
15019 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15020 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15021 dired.c's scmp function, had undefined behavior.
15022 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15023 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15024 * buffer.h: ... to here, because these macros use current_buffer,
15025 and the new implementation with inline functions needs to have
15026 current_buffer in scope now, rather than later when the macros
15028 (downcase, upcase1): New static inline functions.
15029 (DOWNCASE, UPCASE1): Reimplement using these functions.
15030 This avoids undefined behavior in expressions like
15031 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15032 from race conditions in accessing the global variables
15033 case_temp1 and case_temp2.
15034 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15035 * lisp.h (case_temp1, case_temp2): Remove their decls.
15036 * character.h (ASCII_CHAR_P): Move from here ...
15037 * lisp.h: ... to here, so that the inline functions mentioned
15038 above can use them.
15040 * dired.c (directory_files_internal_unwind): Now static.
15042 * fileio.c (file_name_as_directory, directory_file_name):

15045 (file_name_as_directory): Use const pointers when appropriate.
15046 (Fexpand_file_name): Likewise. In particular, newdir might
15047 point at constant storage, so make it a const pointer.
15048 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
15049 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15051 (Fset_file_times, Finsert_file_contents, auto_save_error):

15056 to avoid shadowing.
15058 * marker.c (bytepos_to_charpos): Remove; unused.
15060 * lisp.h (verify_bytepos, count_markers): New decls,
15061 so that gcc does not warn that these functions aren't declared.
15063 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
15064 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
15065 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
15066 (copy_text): Remove unused local var.
15068 * filelock.c (within_one_second): Now static.
15069 (lock_file_1): Rename local to avoid shadowing.
15071 * buffer.c (fix_overlays_before): Mark locals as initialized.
15072 (fix_start_end_in_overlays): Likewise. This function should be
15073 simplified by using pointers-to-pointers, but that's a different
15075 (switch_to_buffer_1): Now static.
15076 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15077 (report_overlay_modification): Rename locals to avoid shadowing.
15079 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
15080 Fix pointer signedness issue.
15081 (sys_subshell): Mark local as volatile if checking for lint,
15082 to suppress a gcc -Wclobbered warning that does not seem to be right.
15083 (MAXPATHLEN): Define only if needed.
15085 * process.c (serial_open, serial_configure): Move decls from here ...
15086 * systty.h: ... to here, so that they can be checked.
15088 * fns.c (get_random, seed_random): Move extern decls from here ...
15089 * lisp.h: ... to here, so that they can be checked.
15091 * sysdep.c (reset_io): Now static.
15092 (wait_for_termination_signal): Remove; unused.
15094 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

15097 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
15098 (DENSE_TABLE_SIZE): Remove; unused.
15099 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
15100 (describe_map_tree):
15101 Rename locals to avoid shadowing.
15103 * keyboard.c: Declare functions static if they are not used elsewhere.

15188 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
15189 These macros can no longer be used for assignment.

15250 For example, without this patch (encode-time 0 0 0 1 1
15251 1152921504606846976) returns the obviously-bogus value (-948597
15252 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
15253 reports time overflow. See
15254 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
15255 * deps.mk (editfns.o): Depend on ../lib/intprops.h.

15270 * editfns.c (time_overflow): New function, refactoring common code.
15271 (Fformat_time_string, Fdecode_time, Fencode_time):
