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

728 installation tree, as appropriate.
730 * callproc.c (init_callproc_1): Call decode_env_path instead of

765 Remove unnecessary pointer casts.
766 * alloc.c (record_xmalloc): New function.
767 * lisp.h (record_xmalloc): New decl.
768 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
769 more like a function. This is because the pointer cast is not
770 needed. All uses changed.
771 * print.c (print_string, print_error_message): Avoid length recalc.
773 Improve fix for macroexp crash with debugging (Bug#12118).
774 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
775 ARRAY_MARK_FLAG when checking subscripts, because ASET is
776 not supposed to be invoked from the garbage collector.
777 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.

795 headers (most versions of MinGW w32api don't).
796 (get_security_info, create_symbolic_link)
797 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
799 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

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

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

851 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
852 (INLINE_HEADER_END): New macros.
853 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

875 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
877 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
878 This how ASET and AREF are supposed to work, and makes
879 it easier to think about future improvements. See
880 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
881 * charset.h (set_charset_attr): New function.

1383 (DATA_SEG_BITS): Use it.
1384 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
1385 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1386 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1387 not be usable in #if. This simplifies things.
1389 2012-07-26 Juanma Barranquero <lekktu@gmail.com>

1396 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1397 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1398 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1399 Adjust to changes in lisp.h and emacs.c, by using
1400 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1401 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1402 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1403 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
1404 instead of gdb_valbits.
1405 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
1406 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
1407 instead of gdb_array_mark_flag.
1408 (xboolvector): Get size from $->size, not $->header.size.
1409 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1410 (xreload, hook-run, hookpost-run): Remove.
1411 * emacs.c: Include <verify.h>.
1412 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

1416 (gdb_USE_LSB_TAG): New enum constants.
1417 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1418 Also define these as enum constants, so they're visible to GDB.
1419 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
1420 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
1421 as constants, so they're visible to GDB.
1422 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
1423 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
1424 Now enum constants, not macros, so they're visible to GDB.
1425 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1426 more convenient now. All uses changed.
1427 (VALMASK) [USE_LSB_TAG]: Also define in this case.

1440 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
1442 Use typedef for EMACS_INT, EMACS_UINT.
1443 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1444 than macros. This simplifies debugging in the usual case, since
1445 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1446 and it allows expressions involving EMACS_INT casts.
1447 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1449 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

1465 (init_buffer_once): Initialize indirection counters of
1466 buffer_defaults and buffer_local_symbols (for sanity and safety).
1468 2012-07-24 Eli Zaretskii <eliz@gnu.org>

1499 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1501 Swap buffer text indirection counters in Fbuffer_swap_text.
1502 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1503 This avoids crash reported by Christoph Scholtes at
1504 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1506 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1508 * nsmenu.m (Popdown_data): New struct.

1531 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
1533 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
1534 as it's limited by the amount of memory, not by INT_MAX.
1536 2012-07-21 Eli Zaretskii <eliz@gnu.org>
1538 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

1689 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
1691 * eval.c (Fdefvar): Don't check constants since we only set the var if
1692 it's not yet defined anyway (bug#11904).

1695 * keyboard.c (command_loop_1): Set it.
1696 * cmds.c (Fself_insert_command): Use it to only remove boundaries that

2281 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
2282 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
2283 not functions. All uses rewritten to use the following, respectively:
2284 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
2285 (add_emacs_time, sub_emacs_time): New functions.
2286 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

2312 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2313 * nsterm.m (ns_term_init):
2314 Avoid the need for strncpy, by using build_string or
2315 make_unibyte_string directly. Use dtoastr, not snprintf.
2316 * process.c (Fmake_network_process): Diagnose service names that
2317 are too long, rather than silently truncating them or creating
2318 non-null-terminated names.
2319 (Fnetwork_interface_info): Likewise, for interface names.
2320 * sysdep.c (system_process_attributes) [GNU_LINUX]:
2321 Prefer sprintf to strncat.
2322 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

2334 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
2335 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

2348 Optimize pure C strings initialization.
2349 * lisp.h (make_pure_string): Fix prototype.
2350 (build_pure_c_string): New function, defined as static inline. This
2351 provides a better opportunity to optimize away calls to strlen when
2352 the function is called with compile-time constant argument.
2353 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2354 argument, adjust users accordingly. Use build_pure_c_string where
2356 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2357 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
2358 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
2360 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2362 Avoid calls to strlen in miscellaneous functions.
2363 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
2364 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
2365 * lread.c (openp): Likewise.

2369 Avoid calls to strlen in path processing functions.
2370 * fileio.c (file_name_as_directory): Add comment. Change to add
2371 srclen argument and return the length of result. Adjust users

2375 Adjust users accordingly.
2376 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2378 2012-07-10 Glenn Morris <rgm@gnu.org>

2385 * s/gnu.h (DATA_START): Move definitions to configure.
2387 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2388 We include usg5-4-common.h, which defines them both.
2390 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2391 O_RDONLY already includes it).
2393 Stop ns builds setting the EMACSLOADPATH environment variable.
2394 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2395 Now it does not set EMACSLOADPATH, just returns the load-path string.
2396 * nsterm.h: Update accordingly.
2397 * lread.c [HAVE_NS]: Include nsterm.h.
2398 (init_lread) [HAVE_NS]: Use ns_load_path.

2401 2012-07-09 Glenn Morris <rgm@gnu.org>
2403 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2404 since the included bsd-common.h does so.
2406 Stop ns builds setting the EMACSPATH environment variable.
2407 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2408 (ns_init_paths): Do not set EMACSPATH.
2409 * nsterm.h (ns_exec_path): Add it.
2410 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2413 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2415 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2417 * process.c (wait_reading_process_output): 'waitchannels' was unset
2418 when read_kbd || !NILP (wait_for_cell); fix this.
2420 Add GCC-style 'const' attribute to functions that can use it.
2421 * character.h (char_resolve_modifier_mask):
2422 * keyboard.h (make_ctrl_char):
2423 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

2432 Add decls with ATTRIBUTE_CONST.
2434 Minor improvements to make_formatted_string.
2435 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2436 where int is good enough, as vsprintf returns an int.
2437 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2439 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2441 Use make_formatted_string to avoid double length calculation.
2442 * lisp.h (make_formatted_string): New prototype.
2443 * alloc.c (make_formatted_string): New function.
2444 * buffer.c (Fgenerate_new_buffer_name): Use it.

2466 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2468 Move marker debugging code under MARKER_DEBUG.
2469 * marker.c (MARKER_DEBUG): Move marker debugging code under
2470 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2471 for bootstrap with --enable-checking (~3x slowdown reported
2472 by Juanma Barranquero <lekktu@gmail.com>).
2473 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2475 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2477 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2478 See <http://bugs.gnu.org/11825#29>.
2480 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2482 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2483 has no font, use the frame's font. (Bug#11813)
2484 (display_line): Add commentary about displaying truncation glyphs
2486 (produce_special_glyphs): Move here from term.c.
2488 * term.c (produce_special_glyphs): Move to xdisp.c.
2490 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2493 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2495 * xdisp.c (display_line): Avoid warning about implicit declaration
2498 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2500 * lisp.h: Remove empty conditional.
2502 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2504 * lread.c (load_path_check): Now static.
2506 Fix some minor --with-ns problems found by static checking.
2507 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2508 (x_set_font) [!HAVE_X_WINDOWS]:
2509 * image.c (xpm_load_image) [HAVE_NS]:
2510 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2511 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2512 Remove unused local.
2513 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2514 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2515 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2516 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2517 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2518 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2519 Fix pointer signedness problem.
2520 * xfaces.c (FRAME_X_FONT_TABLE):
2521 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2523 2012-07-07 Glenn Morris <rgm@gnu.org>
2525 * lread.c (load_path_check): New function, split from init_lread.
2526 (init_lread): Reorganize. Motivation:
2527 If EMACSLOADPATH is set, check/warn about that rather than the
2528 defaults, which we are not going to use. Hence we can remove
2529 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2530 Don't warn if site-lisp directories are missing.
2531 If not installed, start from a blank load-path, since
2532 PATH_LOADSEARCH refers to the eventual installation directories.
2534 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2536 Support truncation and continuation glyphs on GUI frames, when
2537 fringes are disabled. (Bug#11832)
2538 * xdisp.c (init_iterator): Get dimensions of truncation and
2539 continuation glyphs even if on GUI frames.
2540 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2541 or both, are absent.
2542 (start_display, move_it_in_display_line_to): Handle the case of a
2543 GUI frame without a fringe to display continuation or truncation
2545 (insert_left_trunc_glyphs): Support GUI frames: make sure
2546 truncation glyphs overwrite enough glyphs from the current line to
2547 have sufficient space in pixels.
2548 (display_line): Support truncation and continuation glyphs on GUI
2549 frames. If some spare pixels are left on the line after inserting
2550 the truncation glyphs, fill that space with a stretch glyph of a
2551 suitably computed width.
2553 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2554 produce_glyphs, to support GUI sessions.
2556 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2558 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2560 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2562 Do not require float-time's arg to fit in time_t (Bug#11825).
2563 This works better on hosts where time_t is unsigned, and where
2564 float-time is applied to the (negative) difference between two times.
2565 * editfns.c (decode_time_components): Last arg is now double *,
2566 not int *, and means to store all the result as a double, without
2567 worrying about whether the seconds part fits in time_t.
2568 All callers changed.
2569 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2570 All callers changed.
2571 (Ffloat_time): Do not fail merely because the specified time falls
2572 outside of time_t range.
2574 2012-07-07 Glenn Morris <rgm@gnu.org>
2576 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
2577 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
2578 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
2580 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
2582 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2583 Update dependencies.
2585 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2587 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2589 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

2591 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2592 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2593 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2594 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2596 * xfont.c (compare_font_names): Redo to omit the need for casts.
2598 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2600 * xfns.c (Fx_change_window_property): Doc fix.
2601 * w32fns.c (Fx_change_window_property): Doc fix.
2603 * w32fns.c (Fx_window_property): Accept the same arguments as the
2604 X Windows version. Doc fix.
2605 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2607 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2608 Eli Zaretskii <eliz@gnu.org>
2610 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2611 Windows-specific code from nt/config.nt moved here.
2612 Obsolete settings removed.
2614 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2616 * process.c: Avoid unnecessary calls to gettime.
2617 (wait_reading_process_output): Don't get the time of day
2618 when gobbling data immediately and not waiting, as there's no need
2619 for it in that case. This removes a FIXME.
2621 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2623 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2624 is defined (Bug#11768).
2626 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2628 Fix marker debugging code.
2629 * marker.c (byte_char_debug_check): Do not perform the check
2630 if buffer is not multibyte.
2631 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2632 Call byte_char_debug_check with correct arguments.
2634 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2636 Compile marker debugging code only if ENABLE_CHECKING is defined.
2637 * marker.c (byte_char_debug_check, count_markers):
2638 Use only if ENABLE_CHECKING is defined.
2639 (byte_debug_flag): Remove.
2640 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2641 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2643 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2645 Avoid code repetition in marker-related functions.
2646 * marker.c (attach_marker): New function.
2647 (Fset_marker, set_marker_restricted, set_marker_both)
2648 (set_marker_restricted_both): Use it.
2649 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2650 Consistently rename charno to charpos.
2651 (marker_position): Add eassert.
2652 (marker_byte_position): Convert to eassert.
2654 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

2670 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2671 * window.c (save_window_save): Likewise.
2673 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2675 Do not use Fdelete_overlay in delete_all_overlays
2676 to avoid redundant calls to unchain_overlay.
2677 * buffer.c (drop_overlay): New function.
2678 (delete_all_overlays, Fdelete_overlay): Use it.
2679 * minibuf.c (get_minibuffer): Fix comment.
2681 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2683 Port to OpenBSD 5.1 amd64.
2684 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2685 This is needed for OpenBSD, and should be harmless on all BSD systems.
2686 Also, include <sys/sysctl.h>, as it should be available on all
2687 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2688 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2689 use p_pid member, not kp_proc.pid.
2691 2012-07-06 Glenn Morris <rgm@gnu.org>
2693 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2695 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2697 More xmalloc and related cleanup.
2698 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2699 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
2700 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
2701 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
2702 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
2703 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
2704 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2705 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2706 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2708 Omit needless casts involving void * pointers and allocation.
2709 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2710 as the former is more robust if P's type is changed.
2711 Prefer xzalloc to xmalloc + memset 0.
2712 Simplify malloc-or-realloc to realloc.
2713 Don't worry about xmalloc returning a null pointer.
2714 Prefer xstrdup to xmalloc + strcpy.
2715 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2717 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2718 alloca of a constant.
2720 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2722 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2723 hscroll is larger than the line width. Fixes long and futile
2724 looping inside extend_face_to_end_of_line (on a TTY) producing
2725 glyphs that are not needed and thrown away.
2727 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2729 * marker.c (set_marker_restricted_both): Simplify by using

2739 not defined (Bug#11768).
2740 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
2741 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2742 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2743 followed by gtk_box_set_homogeneous (Bug#11768).
2744 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2745 (update_theme_scrollbar_width, xg_create_scroll_bar):
2746 Use gtk_scrollbar_new (Bug#11768).
2747 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

2755 * xdisp.c (window_hscroll_limited): New function.
2756 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2757 coordinates when window's hscroll is set to insanely large
2760 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2762 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

2823 * fileio.c (time_error_value): Check the right error number.
2824 Problem reported by Troels Nielsen in
2825 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

2829 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2830 This should be fixed in a better way; see Eli Zaretskii in
2831 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2832 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2834 * fileio.c (time_error_value): Rename from special_mtime.
2835 The old name's problems were noted by Eli Zaretskii in
2836 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2838 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2839 This variable's comment says Emacs needs at least one GDB-visible
2840 symbol of type enum pvec_type, to work around GDB problems.
2841 The symbol's value doesn't matter.
2843 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2844 that causes compilation to fail on pre-C99 compilers.
2846 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2848 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2849 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2851 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2853 * buffer.c (init_buffer_once): Fix initialization of
2854 headers for buffer_defaults and buffer_local_symbols.
2855 Reported by Juanma Barranquero <lekktu@gmail.com>.
2857 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2859 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2860 * lisp.h (enum pvec_type): Use fewer bits.
2861 (PSEUDOVECTOR_SIZE_BITS): New constant.
2862 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2863 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2864 change in pvec_type.
2865 (PSEUDOVECTOR_TYPEP): New macro.
2866 (TYPED_PSEUDOVECTORP): Use it.
2867 * fns.c (internal_equal): Adapt code to extract pvectype.

2871 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2872 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2873 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2874 abusing vector->header.next.nbytes.
2875 (live_vector_p): Use PVEC_TYPE.
2876 (mark_object): Adapt code to extract pvectype. Use switch.
2878 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2880 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2881 Tighten new eassert a bit.
2883 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2885 Fix compilation with --enable-gcc-warnings and -O1
2887 * doprnt.c (doprnt): Change type of tem to int, initialize
2888 to avoid compiler warning. Add eassert.
2889 * search.c (simple_search): Initialize match_byte to avoid
2890 compiler warning. Add eassert.
2892 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2894 Avoid weird behavior with large horizontal scrolls.
2895 Without this change, for example, large hscroll values would
2896 mess up Emacs's display on Fedora 15 x86, presumably due to
2897 overflows in int calculations in the display code.
2898 Also, if buffers had long lines, Emacs would freeze.
2899 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2900 (set_window_hscroll): New function, containing the old guts of
2901 Fset_window_hscroll. Return the clipped value.
2902 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2903 This avoids the need to check against PTRDIFF_MAX.
2905 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2907 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2909 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2911 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2913 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2914 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2915 since GCC 4.4.6 issues a bogus warning for them.
2917 Fix bugs in file timestamp newness comparisons.
2918 * fileio.c (Ffile_newer_than_file_p):
2919 * lread.c (Fload): Use full timestamp resolution of files,
2920 not just the 1-second resolution, so that files that are only
2921 slightly newer still count as newer.
2922 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2923 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2925 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2927 * fileio.c: Improve handling of file time marker. (Bug#11852)
2928 (special_mtime): New function.
2929 (Finsert_file_contents, Fverify_visited_file_modtime):
2930 Use it to set special mtime values consistently.
2932 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2934 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2935 marker for non-existing file. (Bug#11852)
2937 2012-07-03 Glenn Morris <rgm@gnu.org>
2939 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2940 and did not make it into globals.h).
2942 2012-07-03 Tom Tromey <tromey@redhat.com>
2944 * window.c (Fset_window_margins, Fset_window_fringes)
2945 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2946 * textprop.c (Fprevious_property_change): No longer static.
2947 * syntax.c (Fsyntax_table_p): No longer static.

2969 * intervals.h: Remove EXFUNs.
2970 * fontset.h: Remove EXFUN.

2978 * xterm.h: Remove EXFUN.
2980 2012-07-03 Glenn Morris <rgm@gnu.org>
2982 * lisp.h (Frandom): Make it visible to C.
2983 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2984 buffer for invisible buffers. (Bug#1229)
2986 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2988 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2989 values which aren't power of 2.
2990 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
2991 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2994 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2996 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2998 * alloc.c (mark_object): Revert part of last patch to use `switch'.
3000 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3002 * alloc.c (allocate_vector_block): Remove redundant
3003 calls to mallopt if DOUG_LEA_MALLOC is defined.
3004 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
3005 avoid calls to mallopt if zero_vector is returned.
3007 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3009 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
3010 is enabled, avoid dereferencing NULL current_sblock if
3013 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3015 Cleanup basic buffer management.
3016 * buffer.h (struct buffer): Change layout to use generic vector
3017 marking code. Fix some comments. Change type of 'clip_changed'
3018 to bitfield. Remove unused #ifndef old.
3019 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
3020 (GET_OVERLAYS_AT): Fix indentation.
3021 (for_each_per_buffer_object_at): New macro.

3025 * alloc.c (allocate_buffer): Adjust to match new layout of
3026 struct buffer. Fix comment.
3027 (mark_overlay): New function.

3030 (mark_object): Use it. Adjust marking of misc objects
3031 and related comments.
3033 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
3035 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
3036 wrapper that is not needed because the wrapped code is a no-op (zero
3037 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
3038 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
3040 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
3042 * alloc.c (mark_buffer): Simplify. Remove prototype.
3043 (mark_object): Add comment. Reorganize marking of vector-like
3044 objects. Use CHECK_LIVE for all vector-like objects except buffers
3045 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
3046 Avoid redundant calls to mark_vectorlike for bool vectors.
3048 2012-06-30 Glenn Morris <rgm@gnu.org>
3050 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
3052 * epaths.in (PATH_SITELOADSEARCH): New.
3053 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
3054 This is rather than relying on --enable-locallisppath elements
3055 having "site-lisp" in their names. (Bug#10208#25, 11658)
3057 2012-06-30 Eli Zaretskii <eliz@gnu.org>
3059 * w32proc.c (sys_select): Accept and ignore one more argument.
3061 * w32.c (emacs_gnutls_pull): Call select with one more argument.
3063 * sysselect.h [DOS_NT]: Don't include sys/select.h.
3064 (pselect) [!MS_DOS]: Redirect to sys_select.
3066 * sysdep.c: Don't include dos.h and dosfns.h.
3068 * process.c (sys_select):
3069 * msdos.c (sys_select): Accept one more argument and ignore it.
3071 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
3072 adapt data types and code to that.
3075 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
3076 which clashes with the gnulib function of the same name.
3078 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3080 * font.c (font_style_to_value, font_style_symbolic)
3081 (font_prop_validate_style): Add type checks for values in
3084 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3086 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3089 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3091 * xdisp.c (try_window_id): Undo last change.
3093 * w32.c (getwd): Adjust commentary about startup_dir.
3094 (init_environment): Always call sys_access, even in non-MSVC
3095 builds. Don't chdir to the directory of the Emacs executable.
3096 This undoes code from 1997 which was justified by the need to
3097 "avoid conflicts when removing and renaming directories". But its
3098 downside was that every relative file name was being interpreted
3099 relative to the directory of the Emacs executable, which can never
3100 be TRT. In particular, it broke sys_access when called with
3101 relative file names.
3102 (sys_access): Map GetLastError to errno.
3104 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3106 * window.h (struct window): Change type of 'fringes_outside_margins'

3110 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3113 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
3115 * gnutls.c (emacs_gnutls_handshake):
3116 Add QUIT to make the loop interruptible.
3118 2012-06-29 Glenn Morris <rgm@gnu.org>
3120 * charset.c (init_charset): Make lack of etc/charsets fatal.
3122 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3124 * editfns.c (region_limit): Fix type mismatch.
3126 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3128 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3129 undefined. Convert from xassert to eassert.
3130 * nsmenu.m: Convert from xassert to eassert.
3131 * nsterm.m: Likewise.
3133 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3135 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3137 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3139 Avoid integer overflow on scroll-left and scroll-right.
3140 * window.c (HSCROLL_MAX): New macro.
3141 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3142 overflow when requested scroll falls outside ptrdiff_t range.
3144 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3146 * window.h (struct window): Change type of 'hscroll',
3147 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3148 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3149 Adjust users accordingly.
3150 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3151 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3152 from EMACS_INT to ptrdiff_t.
3153 (make_window): Omit redundant initialization.
3155 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
3157 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
3159 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3161 * window.h (struct window): Change type of 'use_time' and
3162 'sequence_number' from Lisp_Object to int.
3163 * frame.c (make_frame): Adjust users accordingly.

3166 (make_window): Likewise.
3168 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3170 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
3171 enabled with --enable-checking=[all,glyphs] configure option.
3172 Fix GLYPH_DEBUG usage assuming that it may be undefined,
3173 adjust comments accordingly.

3294 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3296 Use sprintf return value instead of invoking strlen on result.
3297 In the old days this wasn't portable, since some sprintf
3298 implementations returned char *. But they died out years ago and
3299 Emacs already assumes sprintf returns int.
3300 Similarly for float_to_string.
3301 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

3308 * xfns.c (syms_of_xfns):
3309 Use sprintf or float_to_string result to avoid need to call strlen.
3310 * data.c (Fnumber_to_string):
3311 Use make_unibyte_string, since the string must be ASCII.
3312 * lisp.h, print.c (float_to_string): Now returns int length.
3313 * term.c (produce_glyphless_glyph):
3314 Use sprintf result rather than recomputing it.
3316 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3317 * Makefile.in (ALL_CFLAGS):
3318 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
3319 * gmalloc.c, regex.c: Include <config.h> unconditionally.

3343 sprintf already null-terminates its output.
3345 * xfns.c (x_window): Remove redundant cast.
3347 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3349 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
3350 `const char *' to `char *' to avoid compiler warning.
3352 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3354 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
3355 instead of truncating it to 63 (admittedly a generous limit).
3357 * process.c: Fix spelling and caps in comments.

3410 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3412 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

3414 * dispnew.c (Fsleep_for, sit_for):
3415 * keyboard.c (kbd_buffer_get_event):
3416 * process.c (Faccept_process_output):
3417 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3418 This improves on the previous patch, which introduced a bug
3419 when time_t is unsigned and as wide as intmax_t.
3420 See <http://bugs.gnu.org/9000#51>.
3422 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3439 Privately reported by Herbert J. Skuhra.
3440 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

3443 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3445 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3448 last argument of make_unibyte_string.
3450 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
3451 language ID in the event parameters.
3453 * w32term.c (w32_read_socket): Put the new keyboard codepage into
3454 event.code, not the obscure "character set ID".

3485 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3487 Support higher-resolution time stamps (Bug#9000).
3488 The time stamps are only nanosecond-resolution at the C level,
3489 since that's the best that any real-world system supports now.
3490 But they are picosecond-resolution at the Lisp level, as that's
3491 easy, and leaves room for future OS improvements.
3493 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3496 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3497 Don't get current time unless it's needed.
3499 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3500 now provides it if it's absent.
3501 (start_atimer): Port to higher-res time stamps.
3502 Check for time stamp overflow. Don't get current time more
3503 often than is needed.
3505 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3506 Include systime.h, not time.h.
3507 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3509 * dired.c: Include stat-time.h.
3510 (Ffile-attributes): File times now have higher resolution.
3512 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3513 (struct image): Timestamp now has higher resolution.
3515 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3516 has at least microseconds now. All uses removed.
3517 (update_frame, update_single_window, update_window, update_frame_1)
3518 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3519 (duration_to_sec_usec): Remove; no longer needed.
3521 * editfns.c (time_overflow): Now extern.
3522 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3523 (float-time, Fformat_time_string, Fcurrent_time_string)

3527 (decode_time_components, lisp_seconds_argument): New functions.
3528 (make_time): Now static.
3529 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3530 Report an error if the time is invalid, rather than having the caller
3533 * fileio.c: Include <stat-time.h>
3534 (Fcopy_file): Copy higher-resolution time stamps.
3535 Prefer to set the time stamp via a file descriptor if that works.

3537 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3538 (Fvisited_file_modtime, Fset_visited_file_modtime):
3539 Support higher-resolution time stamps.
3541 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3543 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3545 * image.c (prepare_image_for_display, clear_image_cache)
3546 (lookup_image): Port to higer-resolution time stamps.
3548 * keyboard.c (start_polling, bind_polling_period):
3549 Check for time stamp overflow.
3550 (read_char, kbd_buffer_get_event, timer_start_idle)
3551 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3552 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3553 Port to higher-resolution time stamps. Do not assume time_t is signed.
3554 (decode_timer): New function. Timers are now vectors of length 9,
3555 not 8, to accommodate the picosecond component.
3556 (timer_check_2): Use it.
3558 * nsterm.m (select_timeout, timeval_subtract): Remove.
3559 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3560 as they're a bit more accurate and handle overflow better.
3561 (ns_select): Change prototype to be compatible with pselect.
3562 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3563 * nsterm.h (ns_select): Adjust prototype.
3565 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3566 us-resolution time stamps.
3567 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3569 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3571 * lisp.h (time_overflow): New decl.
3572 (wait_reading_process_output): First arg is now intmax_t, not int,
3573 to accommodate larger waits.
3575 * process.h (struct Lisp_Process.read_output_delay):
3576 Now counts nanoseconds, not microseconds.
3577 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3579 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3580 (wait_reading_process_output):
3581 Port to ns-resolution time stamps.
3582 (Faccept_process_output, wait_reading_process_output):
3583 Check for time stamp overflow. Do not assume time_t is signed.
3584 (select_wrapper): Remove; we now use pselect.
3585 (Fprocess_attributes): Now generates ns-resolution time stamps.
3587 * sysdep.c: Include utimens.h. Don't include utime.h
3588 or worry about struct utimbuf; gnulib does that for us now.
3589 (gettimeofday): Remove; gnulib provides a substitute.
3590 (make_timeval): New function.
3591 (set_file_times): Now sets ns-resolution time stamps.
3592 New arg FD; all uses changed.
3593 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3594 (system_process_attributes):
3595 Now returns ns-resolution time stamp. All uses changed.
3596 Check for time stamp overflow.
3598 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3599 provides a substitute now.
3601 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3602 since it guarantees struct timespec.
3603 (EMACS_TIME): Now struct timespec, so that we can support
3604 ns-resolution time stamps.
3605 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3606 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3607 (EMACS_USECS): Remove.
3608 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3609 so multiply the arg by 1000 before storing it.
3610 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3612 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3613 Port to ns-resolution time stamps.
3614 (EMACS_TIME_NEG_P): Remove; replaced by....
3615 (EMACS_TIME_SIGN): New macro.
3616 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3617 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

3619 (make_timeval, make_lisp_time, decode_time_components): New decls.
3620 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3621 that it mishandled time_t overflow. You can't compare by subtracting!
3622 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3623 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3625 * term.c: Include <sys/time.h>.
3626 (timeval_to_Time): New function, for proper overflow wraparound.
3627 (term_mouse_position, term_mouse_click): Use it.
3629 * undo.c (record_first_change): Support higher-resolution time stamps
3631 (Fprimitive_undo): Use them when restoring time stamps.
3633 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3634 (w32_get_internal_run_time):
3635 Port to higher-resolution Emacs time stamps.
3636 (ltime): Now accepts single 64-bit integer, as that's more convenient
3639 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3641 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3642 for compatibility with pselect. Support ns-resolution time stamps.
3644 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3646 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3647 Check for time stamp overflow, and support ns-resolution time stamps.
3649 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3650 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3651 (timeval_subtract): Remove; no longer needed.
3652 (XTflash, XTring_bell, x_wait_for_event):
3653 Port to ns-resolution time stamps. Don't assume time_t is signed.
3655 2012-06-22 Chong Yidong <cyd@gnu.org>
3657 * xdisp.c (x_consider_frame_title): Revert last change.
3659 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3661 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3662 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3663 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3664 staticidx goes up to 1597 out of 1600 = 0x640.)
3666 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3668 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3669 Otherwise, the umask might be mistakenly 0 while handling input signals.
3671 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3673 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

3679 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3680 access to `contents' member of Lisp_Vector objects with AREF and ASET
3683 2012-06-19 Chong Yidong <cyd@gnu.org>
3685 * frame.c (delete_frame): When selecting a frame on a different

3938 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3939 Use an inline function on all platforms when using the union type,
3940 since this is simpler and 'static inline' can be used portably

4084 * doprnt.c (doprnt): Truncate multibyte char correctly.
4085 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4086 would mishandle a string argument "Xc" if X was a multibyte
4087 character of length 2: it would truncate after X's first byte
4088 rather than including all of X.

4165 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4167 Pacify gcc -Wdouble-precision when using Xaw.
4168 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
4169 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
4170 Use 'float' consistently, rather than 'float' in most places
4171 and 'double' in a couple of places.
4173 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4175 * xdisp.c (handle_stop): Detect whether we have overlay strings
4176 loaded by testing it->current.overlay_string_index to be
4177 non-negative, instead of checking whether n_overlay_strings is
4178 positive. (Bug#11587)
4180 2012-05-31 Chong Yidong <cyd@gnu.org>
4182 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
4184 * doc.c (Fsubstitute_command_keys): Doc fix.
4186 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4188 * search.c (search_buffer): Remove calls to
4189 r_alloc_inhibit_buffer_relocation, as it is now called by
4190 maybe_unify_char, which was the cause of relocation of buffer text
4193 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4195 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4196 for the duration of call to load_charset, to avoid problems with
4197 callers of maybe_unify_char that access buffer text through C
4200 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4201 decrement the inhibition flag, instead of just setting or
4204 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4206 Remove obsolete '#define static' cruft.
4207 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
4208 This #undef was "temporary" in 2000; it is no longer needed
4209 now that '#define static' has gone away.
4210 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
4211 (gray_bitmap_bits): Remove; no longer needed.
4212 All uses replaced with definiens.
4213 * xterm.c: Include "bitmaps/gray.xbm".
4215 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4217 Clean up __executable_start, monstartup when --enable-profiling.
4218 The following changes affect the code only when profiling.
4219 * dispnew.c (__executable_start): Rename from safe_bcopy.
4220 Define only on platforms that need it.
4221 * emacs.c: Include <sys/gmon.h> when profiling.
4222 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
4223 (__executable_start): Remove decl, since lisp.h does it now.
4224 (safe_bcopy): Remove decl; no longer has that name.
4225 (main): Coalesce #if into single bit of code, for simplicity.
4226 Cast pointers to uintptr_t, since standard libraries want integers
4228 * lisp.h (__executable_start): New decl.
4230 2012-05-31 Glenn Morris <rgm@gnu.org>
4232 * image.c (Fimagemagick_types): Doc fix.
4234 2012-05-30 Jim Meyering <meyering@redhat.com>
4236 * callproc.c (Fcall_process_region): Include directory component
4237 in mkstemp error message (Bug#11586).
4239 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4241 * alloc.c, lisp.h (make_pure_vector): Now static.
4243 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

4248 * data.c (Fdefalias): Purify definition, except for keymaps.
4249 (Qdefun): Move from eval.c.
4250 * lisp.h (Qdefun): Remove.
4251 * lread.c (read1): Tiny simplification.
4253 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4255 Do not create empty overlays with the evaporate property (Bug#9642).
4256 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4257 Bug#9642, but explicitly check that the buffer the overlay would
4258 be moved to is live and rearrange lines to make sure that errors
4259 will not put the overlay in an inconsistent state.
4260 (Fdelete_overlay): Cosmetics.
4262 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4264 * w32term.c (my_bring_window_to_top): New function.
4265 (x_raise_frame): Use handle returned by DeferWindowPos, which
4266 could be different from the original one.
4267 Call my_bring_window_to_top instead of my_set_foreground_window.
4270 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4271 by calling BringWindowToTop.
4273 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4274 (WM_EMACS_END): Increase by one.
4276 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4278 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4279 This avoids undefined behavior that might cause the eassert
4280 to not catch an out-of-range value.
4282 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4284 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4285 Update dependencies.
4287 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4289 * bidi.c (bidi_mirror_char): Fix last change.
4291 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
4293 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
4294 when referring to sectname field in printf format.
4296 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4298 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4299 Only r_alloc_inhibit_buffer_relocation needed to be added;
4300 the others were already declared.
4302 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4303 before checking whether it's out of range. Put the check inside
4305 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4307 2012-05-27 Ken Brown <kbrown@cornell.edu>
4309 * callproc.c (Fcall_process): Restore a line that was accidentally
4310 commented out in the 2011-02-13 change (bug#11547).
4312 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4314 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4315 defined on ralloc.c.
4317 * buffer.c [REL_ALLOC]: Remove prototypes of
4318 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4319 they are now on lisp.h.
4321 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4323 * search.c (search_buffer): Use it to inhibit relocation of buffer
4324 text while re_search_2 is doing its job, because re_search_2 is
4325 passed C pointers to buffer text. (Bug#11519)
4327 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4330 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4331 state after an additional call to move_it_in_display_line_to, keep
4332 the values of it->max_ascent and it->max_descent found for the
4334 (pos_visible_p): Revert the comparison against bottom_y to what it
4335 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4338 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4340 Fix coding-related core dumps with gcc -ftrapv.
4341 The code was computing A - B, where A and B are pointers, and B is
4342 random garbage. This can lead to core dumps on platforms that
4343 have special pointer registers, and it also leads to core dumps on
4344 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4345 A - B only when B is initialized properly.
4346 * coding.c (coding_set_source, coding_set_destination): Return void.
4347 (coding_change_source, coding_change_destinations): New functions,
4348 with the old behaviors of coding_set_source and coding_set_destination.
4349 All callers that need an offset changed to use these new functions.
4351 2012-05-26 Glenn Morris <rgm@gnu.org>
4353 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4355 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4357 Extend mouse support on W32 text-mode console.
4358 * xdisp.c (draw_row_with_mouse_face):
4359 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4361 * w32console.c: Include window.h.
4362 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4364 (initialize_w32_display): Initialize mouse-highlight data.
4366 * w32inevt.c: Include termchar.h and window.h.
4367 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4368 moves, call note_mouse_highlight. If help_echo changed, call
4369 gen_help_event to produce help-echo message in the echo area.
4370 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4373 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4375 * lread.c (read1): Simplify slightly to avoid an overflow warning
4376 with GCC 4.7.0 on x86-64.
4378 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4380 * bidi.c (bidi_mirror_char): Revert last change: an int is
4381 definitely wide enough here.
4383 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4385 Fix integer width and related bugs (Bug#9874).
4386 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
4387 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
4388 (string_bytes, check_sblock, allocate_string_data):
4389 (compact_small_strings, Fmake_bool_vector, make_string)
4390 (make_unibyte_string, make_multibyte_string)
4391 (make_string_from_bytes, make_specified_string)
4392 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
4393 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4395 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4396 (allocate_pseudovector):
4397 Use int, not EMACS_INT, where int is wide enough.
4398 (inhibit_garbage_collection, Fgarbage_collect):
4399 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4400 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4401 int might not be wide enough.
4402 (bidi_cache_search, bidi_cache_find, bidi_init_it)
4403 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4404 (bidi_at_paragraph_end, bidi_find_paragraph_start)
4405 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4406 (bidi_level_of_next_char, bidi_move_to_visually_next):
4407 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4408 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4409 (Fkill_buffer, Fset_buffer_major_mode)
4410 (advance_to_char_boundary, Fbuffer_swap_text)
4411 (Fset_buffer_multibyte, overlays_at, overlays_in)
4412 (overlay_touches_p, struct sortvec, record_overlay_string)
4413 (overlay_strings, recenter_overlay_lists)
4414 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4415 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4416 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4417 (Foverlay_recenter, last_overlay_modification_hooks_used)
4418 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4419 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4420 (validate_region): Omit unnecessary test for b <= e,
4421 since that's guaranteed by the previous test.
4422 (adjust_overlays_for_delete): Avoid pos + length overflow.
4423 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4424 (report_overlay_modification):
4425 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4426 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4427 Omit pointer cast, which isn't needed anyway, and doesn't work
4428 after the EMACS_INT -> ptrdiff_t change.
4429 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4430 * buffer.h: Adjust decls to match defn changes elsewhere.
4431 (struct buffer_text, struct buffer):

4433 Use EMACS_INT, not int, where int might not be wide enough.
4434 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
4435 not int, to avoid needless 32-bit limit on 64-bit hosts.
4436 (exec_byte_code): Use tighter memory-full test, one that checks
4437 for alloca overflow. Don't compute the address of the object just
4438 before an array, as that's not portable. Use EMACS_INT, not
4439 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4440 * callint.c (Fcall_interactively):
4441 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4442 * callproc.c (call_process_kill, Fcall_process):
4443 Don't assume pid_t fits into an Emacs fixnum.
4444 (call_process_cleanup, Fcall_process, child_setup):

4446 (call_process_cleanup, Fcall_process, delete_temp_file)
4447 (Fcall_process_region):
4448 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4449 (Fcall_process): Simplify handling of volatile integers.
4450 Use int, not EMACS_INT, where int will do.
4451 * casefiddle.c (casify_object, casify_region, operate_on_word)
4452 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4453 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4454 (casify_object): Avoid integer overflow when overallocating buffer.
4455 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4456 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4457 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4458 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4459 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4460 integers are now checked earlier. All uses replaced with XINT.
4462 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4463 For CCL_MapSingle, check that content and value are in int range.
4464 (ccl_driver, Fregister_code_conversion_map):
4465 Check that Vcode_version_map_vector is a vector.
4466 (resolve_symbol_ccl_program): Check that vector header is in range.
4467 Always copy the vector, so that we can check its contents reliably
4468 now rather than having to recheck each instruction as it's being
4469 executed. Check that vector words fit in 'int'.
4470 (ccl_get_compiled_code, Fregister_ccl_program)
4471 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4472 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4473 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4474 contents are in range.
4475 (Fccl_execute_on_string): Check that status is in range.
4476 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4477 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4478 Accept and return EMACS_INT, not int, because callers can pass values
4480 (c_string_width, strwidth, lisp_string_width, chars_in_text)
4481 (multibyte_chars_in_text, parse_str_as_multibyte)
4482 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
4483 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4484 (string_escape_byte8, Fget_byte):
4485 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4486 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4487 avoid mishandling large integers.
4488 * character.h: Adjust decls to match defn changes elsewhere.
4489 * charset.c (load_charset_map_from_file, find_charsets_in_text)
4490 (Ffind_charset_region):
4491 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4492 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
4493 (load_charset_map_from_vector, Fdefine_charset_internal):
4494 Don't assume fixnum fits in int.
4495 (load_charset_map_from_vector, Fmap_charset_chars):
4496 Remove now-unnecessary CHECK_NATNUMs.
4497 (Fdefine_charset_internal): Check ranges here, more carefully.
4498 Don't rely on undefined behavior with signed left shift overflow.
4499 Don't assume unsigned int fits into fixnum, or that fixnum fits
4500 into unsigned int. Don't require max_code to be a valid fixnum;
4501 that's not true for gb10830 4-byte on a 32-bit host. Allow
4502 invalid_code to be a cons, for the same reason. Require code_offset
4503 to be a character. Avoid int overflow if max_char is close
4505 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4506 this is intended anyway and avoids some undefined behavior.
4507 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4508 INDEX_TO_CODE_POINT, as that's what it expects.
4509 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4510 * charset.h (DECODE_CHAR): Return int, not unsigned;
4511 this is what was intended anyway, and it avoids undefined behavior.
4512 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4513 integer-overflow issues.
4514 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4515 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4516 where the argument is EMACS_INT, and this behavior is not intended.
4517 * chartab.c (Fmake_char_table, Fset_char_table_range)
4518 (uniprop_get_decoder, uniprop_get_encoder):
4519 Don't assume fixnum fits in int.
4520 * cmds.c (move_point): New function, that does the gist of
4521 Fforward_char and Fbackward_char, but does so while checking
4522 for integer overflow more accurately.
4523 (Fforward_char, Fbackward_char): Use it.
4524 (Fforward_line, Fend_of_line, internal_self_insert)
4525 (internal_self_insert):
4526 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4527 Fix a FIXME, by checking for integer overflow when calculating
4528 target_clm and actual_clm.

4560 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4561 (consume_chars): Rewrite to not calculate an address outside buffer.
4562 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
4563 Don't access memory outside of the args array.
4564 (Fdefine_coding_system_internal): Check for charset-id overflow.
4565 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4566 result of ENCODE_CHAR.
4567 * coding.h: Adjust decls to match defn changes elsewhere.

5299 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
5301 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
5303 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
5305 * lread.c (init_obarray): Declare Qt and Qnil as special.
5307 2012-05-14 Glenn Morris <rgm@gnu.org>
5309 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
5310 Put "libexec" before "bin", for the sake of init_callproc_1.
5312 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5314 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
5316 * unexaix.c: Port to more-recent AIX compilers.
5317 (report_error, report_error_1, make_hdr, copy_sym)
5318 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
5319 Make arguments const char *, not char *, to avoid violations of C
5320 standard and to fix some AIX warnings reported by Gilles Pion.
5322 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5324 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
5325 already have overlays loaded.
5326 (handle_single_display_spec): Before returning without displaying
5327 fringe bitmap, synchronize the bidi iterator with the main display
5328 iterator, by calling iterate_out_of_display_property.
5329 (iterate_out_of_display_property): Detect buffer iteration by
5330 testing that it->string is a Lisp string.
5331 (get_next_display_element): When the current object is exhausted,
5332 and there's something on it->stack, call set_iterator_to_next to
5333 proceed with what's on the stack, instead of returning zero.
5334 (set_iterator_to_next): If called at the end of a Lisp string,
5335 proceed to consider_string_end without incrementing string
5336 position. Don't increment display vector index past the end of
5337 the display vector. (Bug#11417)
5338 (pos_visible_p): Don't report a position visible when move_it_to
5339 stopped at the last line of window, which happens to be scanned
5340 backwards by the bidi iteration. (Bug#11464)
5342 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5344 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5345 and right-margin display specs even if the spec is invalid or we
5346 are on a TTY, and thus unable to display on the fringes.
5347 That's because the text with the property will not be displayed anyway,
5348 so we need to signal to the caller that this is a "replacing"
5349 display spec. This fixes display when the spec is invalid or we
5352 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5354 * unexaix.c (make_hdr): Fix typo in prototype.
5355 This bug broke the build on AIX. Problem reported by Gilles Pion.
5357 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5359 * keyboard.c (kbd_buffer_get_event): Read special events also in
5360 batch mode. (Bug#11415)
5362 2012-05-12 Glenn Morris <rgm@gnu.org>
5364 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5366 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5368 * lisp.mk (lisp): Add newcomment.elc.
5370 2012-05-12 Glenn Morris <rgm@gnu.org>
5372 * Makefile.in (MKDIR_P): New, set by configure.
5373 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5375 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5377 Remove unused function hourglass_started.
5378 * dispextern.h (hourglass_started):
5379 * w32fns.c (hourglass_started):
5380 * xdisp.c (hourglass_started): Remove.
5382 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5384 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5385 Update dependencies.
5387 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5389 * xgselect.c (xg_select): Put maxfds+1 into a var.
5390 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5392 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5394 2012-05-10 Dave Abrahams <dave@boostpro.com>
5396 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5397 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5399 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5401 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5402 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5403 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5404 Initialize xd_registered_buses.
5406 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5408 Untag more efficiently if USE_LSB_TAG.
5409 This is based on a proposal by YAMAMOTO Mitsuharu in
5410 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5411 For an admittedly artificial (nth 8000 longlist) benchmark on
5412 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5413 Emacs's overall text size by 1%.
5414 * lisp.h (XUNTAG): New macro.
5415 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5416 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5417 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5418 * eval.c (Fautoload):
5419 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5420 * frame.h (XFRAME): Use XUNTAG.
5422 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5423 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5424 Remove unportable assumptions about print widths of types like
5426 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5427 intptr_t when converting between pointer and integer, to avoid GCC
5428 warnings about wrong width.
5430 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5432 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5433 stack for each reader_thread, instead of defaulting to 8MB
5434 determined by the linker. This avoids failures in creating
5435 subprocesses on Windows 7, see the discussion in this thread:
5436 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5438 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5440 Fix up display of the *Minibuf-0* buffer in the mini window.
5441 * keyboard.c (read_char): Don't clear the echo area if there's no
5443 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5444 contents of *Minibuf-0*) if there's no message displayed in its stead.
5446 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5448 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5451 2012-05-06 Chong Yidong <cyd@gnu.org>
5453 * lisp.mk (lisp): Update.
5455 2012-05-05 Jim Meyering <meyering@redhat.com>
5457 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5459 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5461 * data.c (PUT_ERROR): New macro.
5462 (syms_of_data): Use it. Add new error type `user-error'.
5463 * undo.c (user_error): New function.
5464 (Fprimitive_undo): Use it.
5465 * print.c (print_error_message): Adjust print style for `user-error'.
5466 * keyboard.c (user_error): New function.
5467 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5469 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5471 Do not limit current-time-string to years 1000..9999.
5472 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5473 (Fcurrent_time_string): Support any year that is supported by the
5474 underlying localtime representation. Don't use asctime, as it
5475 has undefined behavior for years outside the range -999..9999.
5477 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5479 Fix race conditions involving setenv, gmtime, localtime, asctime.
5480 Without this fix, interrupts could mess up code that uses these
5481 nonreentrant functions, since setting TZ invalidates existing
5482 tm_zone or tzname values, and since most of these functions return
5483 pointers to static storage.
5484 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5485 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5486 Grow the critical sections to include not just invoking
5487 localtime/gmtime, but also accessing these functions' results
5488 including their tm_zone values if any, and any related TZ setting.
5489 (format_time_string): Last arg is now struct tm *, not struct tm **,
5490 so that the struct tm is saved in the critical section.
5491 All callers changed. Simplify allocation of initial buffer, partly
5492 motivated by the fact that memory allocation needs to be outside
5493 the critical section.
5495 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5497 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5498 with RESET_INTERVAL.
5500 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5501 Remove duplicated buffer name initialization.
5503 2012-05-02 Jim Meyering <jim@meyering.net>
5505 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5507 * xfns.c (x_window): Use xstrdup (Bug#11375).
5509 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5511 * xdisp.c (pos_visible_p): If already at a newline from the
5512 display string before the 'while' loop, don't walk back the glyphs
5513 from it3.glyph_row. Solves assertion violation when the display
5514 string begins with a newline (egg.el). (Bug#11367)
5516 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5518 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5521 2012-05-01 Glenn Morris <rgm@gnu.org>
5523 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5524 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5525 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5526 All were removed before 23.1.
5528 * dispnew.c: Remove HAVE_LIBNCURSES test;
5529 it is always true on relevant platforms.
5531 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5532 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5534 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5536 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5538 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5539 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5542 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5544 Do not avoid creating empty evaporating overlays (Bug#9642).
5545 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5546 That is, do not delete an evaporating overlay if it becomes
5547 empty after its bounds are adjusted to fit within its buffer.
5548 This fix caused other problems, and I'm reverting it until we get
5549 to the bottom of them.
5551 2012-04-27 Chong Yidong <cyd@gnu.org>
5553 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5555 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5557 * xdisp.c (pos_visible_p): If the window start position is beyond
5558 ZV, start the display from buffer beginning. Prevents assertion
5559 violation in init_iterator when the minibuffer window is scrolled
5562 * window.c (window_scroll_pixel_based): Likewise.
5564 2012-04-27 Chong Yidong <cyd@gnu.org>
5566 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5568 2012-04-27 Glenn Morris <rgm@gnu.org>
5570 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5571 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5573 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5575 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5576 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5578 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5580 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5581 display element, check also the underlying string or buffer
5582 character. (Bug#11341)
5584 * w32menu.c: Include w32heap.h.
5585 (add_menu_item): If the call to AppendMenuW (via
5586 unicode_append_menu) fails, disable Unicode menus only if we are
5587 running on Windows 9X/Me.
5589 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5591 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5592 (xgetint): Add missing shift for LSB tags.
5594 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5596 * keyboard.c (read_char): Don't wipe echo area for select window
5597 events: These might get delayed via `mouse-autoselect-window'
5600 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5602 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5603 manipulation of :loaded-from data.
5605 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5607 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5608 now a cons (bug#11311).
5610 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5612 Do not create empty overlays with the evaporate property (Bug#9642).
5613 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5614 if it becomes empty after its bounds are adjusted to fit within
5615 its buffer. Without this fix, in a nonempty buffer (let ((o
5616 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5617 yields an empty overlay that has the evaporate property, which is
5618 not supposed to happen.
5620 Fix minor GTK3 problems found by static checking.
5621 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5622 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5623 (struct _EmacsFixedClass, emacs_fixed_get_type):
5624 Move decls here from emacsgtkfixed.h, since they needn't be public.

5626 (emacs_fixed_class_init): Omit unused local.
5627 (emacs_fixed_child_type): Remove; unused.

5630 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
5631 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5632 (EMACS_FIXED_GET_CLASS): Remove; unused.
5633 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5635 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5636 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5638 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5640 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5641 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5642 (__malloc_size_t, __malloc_ptrdiff_t):
5643 Remove. All uses removed, replaced by the definiens if needed,
5644 since we can assume C89 or better now.
5645 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5646 (protect_malloc_state, align, get_contiguous_space)
5647 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5653 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5654 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5655 Define using prototypes, not old style.
5656 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5657 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5658 (align): Don't assume that signed integer overflow wraps around.
5659 Omit unused local var.
5660 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5661 (_free_internal_nolock, memalign, mallochook, reallochook):
5662 Omit no-longer-needed casts.
5663 (valloc): Use getpagesize, not __getpagesize.
5664 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
5665 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5667 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5669 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
5671 Move functions from C to Lisp. Make non-blocking method calls
5672 the default. Implement further D-Bus standard interfaces.

5708 (Vdbus_message_type_invalid, Vdbus_message_type_method_call)
5709 (Vdbus_message_type_method_return, Vdbus_message_type_error)

5714 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5716 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
5717 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
5718 Do not assume ptrdiff_t is the same width as 'int'.
5720 * alloc.c: Handle unusual debugging option combinations.
5721 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5722 since the two debugging options are incompatible.
5723 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5725 (mem_init, mem_insert, mem_insert_fixup):
5726 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
5727 (NEED_MEM_INSERT): Remove; no longer needed.
5729 2012-04-22 Leo Liu <sdl.web@gmail.com>
5731 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
5733 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5735 * sysdep.c [__FreeBSD__]: Minor cleanups.
5736 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5737 Use Emacs indenting style more consistently. Avoid some casts.
5738 Use 'double' consistently rather than mixing 'float' and 'double'.
5740 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5742 * sysdep.c (list_system_processes, system_process_attributes):
5743 Add implementation for FreeBSD (Bug#5243).
5745 2012-04-21 Andreas Schwab <schwab@linux-m68k.org>
5747 * lisp.mk (lisp): Update.
5749 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
5751 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
5752 It is never used otherwise.

5756 * print.c (print_preprocess): Only check print_depth if print-circle
5758 (print_object): Check for cycles even when print-circle is nil and
5759 print-gensym is t, but only check print_depth if print-circle is nil.
5761 2012-04-20 Chong Yidong <cyd@gnu.org>
5763 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5764 set the status to "failed" and ensure that sentinel is run.

5779 farther than the first row after the header line, if any.
5780 Don't consider the header-line row as "partially visible", even if
5781 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
5783 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5818 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5819 New extern decls, to avoid calling undeclared functions.
5820 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5821 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5822 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

5824 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5825 Remove one incorrect comment and fix another.

5839 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5840 Remove decls. This fixes an "It stinks!".

5844 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5846 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5859 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5860 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5861 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5862 * s/netbsd.h, s/sol2-6.h:
5863 Remove definition of GC_MARK_STACK, since the default now works.
5864 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5865 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5866 no longer the default.
5867 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5869 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5871 * lread.c (lisp_file_lexically_bound_p):

5892 2012-04-11 Daniel Colascione <dancol@dancol.org>
5894 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5895 against is gone. It's better to use vfork now so that when Cygwin
5896 gains a new, working vfork, we use it automatically (bug#10398).
5898 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5916 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5918 * w32.c (w32_delayed_load): Record the full path of the library
5919 being loaded (bug#10424).
5921 2012-04-09 Glenn Morris <rgm@gnu.org>
5923 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5924 not just in the obarray, before snarfing them. (Bug#11036)
5926 * Makefile.in ($(leimdir)/leim-list.el):
5927 Pass EMACS rather than BUILT_EMACS.

5936 Add convenience `GNUTLS_LOG2i' macro.
5938 * gnutls.c (gnutls_log_function2i): Convenience log function.
5939 (emacs_gnutls_read): Use new log functions,
5940 `gnutls_handshakes_tried' process member, and

5951 * minibuf.c (Fread_variable): Callers changed.
5953 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5955 * xdisp.c (set_cursor_from_row): If the display string appears in
5956 the buffer at position that is closer to point than the position
5957 after the display string, display the cursor on the first glyph of
5958 the display string. Fixes cursor display when a 'display' text
5959 property immediately follows invisible text. (Bug#11094)
5961 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5963 composite.c: use 'double' consistently
5964 * composite.c (get_composition_id): Use 'double' consistently
5965 instead of converting 'float' to 'double' and vice versa; this is
5966 easier to understand and avoids a GCC warning.
5968 2012-04-09 Glenn Morris <rgm@gnu.org>
5970 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5971 preparation for dumping it with emacs. (Bug#4789)

5993 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5994 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5995 objects, as mark_maybe_pointer will catch them otherwise.
5996 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5997 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5999 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
6001 Fix typo that broke non-Windows builds.
6002 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

6013 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
6014 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
6015 [!WINDOWSNT]: New macros.
6016 (init_libxml2_functions, libxml2_loaded_p): New functions.
6017 (parse_region): Call fn_xmlCheckVersion instead of using the macro
6018 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
6019 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
6020 Calls xmlCleanupParser only if libxml2 was loaded (or statically
6022 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
6023 Call init_libxml2_functions before calling libxml2 functions.
6024 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
6026 * emacs.c: Don't include libxml/parser.h.
6027 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
6028 xmlCleanupParser directly.
6030 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
6032 2012-04-07 Eli Zaretskii <eliz@gnu.org>

6040 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
6041 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
6042 about subtle differences between FETCH_CHAR* and STRING_CHAR*
6043 macros related to unification of CJK characters. For the details,
6044 see the discussion following the message here:
6045 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
6047 2012-04-04 Chong Yidong <cyd@gnu.org>
6049 * keyboard.c (Vdelayed_warnings_list): Doc fix.
6051 2012-04-01 Eli Zaretskii <eliz@gnu.org>
6053 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

6061 2012-03-31 Eli Zaretskii <eliz@gnu.org>
6063 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
6064 position we get to after a call to move_it_to fails the
6065 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
6066 only if we wind up in a string from display property. (Bug#11063)
6068 * window.c (Fdelete_other_windows_internal): Invalidate the row
6069 and column information about mouse highlight, so that redisplay
6070 restores it after reallocating the glyph matrices. (Bug#7464)
6072 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
6073 string comes from a `display' text property, use the buffer
6074 position of that property as if we actually saw that position in
6076 (move_it_by_lines): Remove the assertion that
6077 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6078 violated when there's a before-string at the beginning of a line.
6081 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6083 * xdisp.c (append_space_for_newline): If the default face was
6084 remapped, use the remapped face for the appended newline.
6085 (extend_face_to_end_of_line): Use the remapped default face for
6086 extending the face to the end of the line.
6087 (display_line): Call extend_face_to_end_of_line when the default
6088 face was remapped. (Bug#11068)

6116 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
6118 2012-03-25 Kenichi Handa <handa@m17n.org>
6120 * dispextern.h (struct glyph): Change the bit length of
6121 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6123 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6125 * s/ms-w32.h (tzname): Include time.h before redirecting to
6126 _tzname. Fixes the MSVC build. (Bug#9960)

6130 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6133 * xterm.c (XTread_socket): Only modify handling_signal if
6134 !SYNC_INPUT. (Bug#11080)
6136 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6138 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6139 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6140 when fetching a multibyte character consumes more bytes than
6141 CHAR_BYTES returns, due to unification of CJK characters in
6142 string_char. (Bug#11073)
6144 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6146 * process.c (wait_reading_process_output): Handle pty disconnect
6147 by refraining from sending oneself a SIGCHLD (bug#10933).

6178 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6180 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6181 that is not from display property, accept the row as a "cursor
6182 row" if one of the string's character has a non-nil `cursor'
6183 property. Fixes cursor positioning when there are newlines in
6184 overlay strings, e.g. in icomplete.el. (Bug#11035)
6186 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6188 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

6192 * eval.c (inhibit_lisp_code): Rename from
6193 inhibit_window_configuration_change_hook; move from window.c.
6195 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6196 * window.c (run_window_configuration_change_hook)
6197 (syms_of_window): Callers changed.
6199 2012-03-11 Chong Yidong <cyd@gnu.org>
6201 * keymap.c (Fkey_description): Doc fix (Bug#9700).
6203 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
6205 2012-03-10 Chong Yidong <cyd@gnu.org>
6207 * frame.c (other_visible_frames): Don't assume the selected frame
6208 is visible (Bug#10955).
6210 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
6212 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6214 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6216 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6217 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6220 2012-03-03 Glenn Morris <rgm@gnu.org>
6222 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6224 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6226 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6227 position past the first glyph_row that ends at ZV. (Bug#10902)
6228 (redisplay_window, next_element_from_string): Fix typos in
6230 (redisplay_window): Pass to move_it_vertically the margin in
6231 pixels, not in screen lines.

6235 * buffer.c (buffer-list-update-hook): Doc fix.
6237 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6239 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6240 push_it before setting up the iterator for the first overlay
6241 string, even if we have an empty string loaded.
6242 (next_overlay_string): If there's an empty string on the iterator
6243 stack, pop the stack. (Bug#10903)
6245 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6247 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6248 Suggested by Stefan Monnier in
6249 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6250 * alloc.c (widen_to_Lisp_Object): New static function.
6251 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6252 and widening them to Lisp_Objects. This would work even if
6253 USE_LSB_TAG is defined and wide integers are used, which might
6254 happen in a future version of Emacs.
6256 2012-02-25 Chong Yidong <cyd@gnu.org>
6258 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6261 * xselect.c (Fx_selection_exists_p): Doc fix.
6262 (x_clipboard_manager_save_all): Print an informative message
6263 before saving to clipboard manager.
6265 2012-02-24 Chong Yidong <cyd@gnu.org>
6267 * keyboard.c (process_special_events): Handle all X selection

6272 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
6273 call when setting menu-bar-lines and tool-bar-lines parameters.
6274 (unwind_create_frame_1): New helper function.
6276 * window.c (inhibit_window_configuration_change_hook): New var.
6277 (run_window_configuration_change_hook): Obey it.
6278 (syms_of_window): Initialize it.
6280 2012-02-22 Chong Yidong <cyd@gnu.org>
6282 * xterm.c (x_draw_image_relief): Add missing type check for

6295 when computing $valmask.
6297 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6298 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6299 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6300 It's useless in that case, and it can cause problems on hosts
6301 that allocate halves of EMACS_INT values separately.
6302 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6303 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6304 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6305 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6306 it avoids undefined behavior on hosts where shifting right by more
6307 than the word width has undefined behavior.
6309 2012-02-19 Chong Yidong <cyd@gnu.org>
6311 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
6312 (Funhandled_file_name_directory, Ffile_name_as_directory)

6331 2012-02-15 Chong Yidong <cyd@gnu.org>
6333 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

6352 as that creates a dangerous corner case.
6354 * window.c (Fdelete_window_internal): Invalidate the mouse
6355 highlight (Bug#9904).
6357 2012-02-12 Glenn Morris <rgm@gnu.org>

6387 2012-02-07 Chong Yidong <cyd@gnu.org>
6389 * buffer.c (Fbuffer_local_variables)
6390 (buffer_lisp_local_variables): Handle unbound vars correctly;
6391 don't let Qunbound leak into Lisp.
6393 2012-02-07 Glenn Morris <rgm@gnu.org>
6395 * image.c (Fimagemagick_types): Doc fix.
6397 * image.c (imagemagick-render-type): Change it from a lisp object

6430 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
6432 Handle overflow when computing char display width (Bug#9496).
6433 * character.c (char_width): Return EMACS_INT, not int.
6434 (char_width, c_string_width): Check for overflow when
6435 computing the width; this is possible now that individual
6436 characters can have unbounded width. Problem introduced
6437 by merge from Emacs 23 on 2012-01-19.
6439 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

6579 (Fmake_directory_internal): Use it.
6580 (do_auto_save_make_dir): Set it, instead of invoking chmod after

7109 behave as if the cursor position were at the window margin.
7111 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7112 and the cursor position is out of bounds, behave as if the cursor

7143 * dispnew.c (verify_row_hash): Call row_hash for computing the
7144 hash code of a row, instead of duplicating code from xdisp.c.
7146 * dispextern.h (row_hash): Add prototype.
7148 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

7182 * image.c (imagemagick_load_image): Fix typo.
7184 2011-11-14 Eli Zaretskii <eliz@gnu.org>
7186 * xdisp.c (display_line): Move the call to

7253 Avoid some portability problems by eschewing 'extern inline' functions.
7254 The trivial performance wins aren't worth the portability hassles; see
7255 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
7257 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

7284 2011-11-07 Eli Zaretskii <eliz@gnu.org>
7286 * w32.c (check_windows_init_file): Don't look for term/w32-win.el
7287 if Vpurify_flag is non-nil. Fixes a crash when running w32 build

7290 2011-11-07 Martin Rudalics <rudalics@gmx.at>
7292 * window.h: Declare delete_all_child_windows instead of

7305 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
7306 This is also needed for porting to any host where GC_MARK_STACK is
7307 not GC_MAKE_GCPROS_NOOPS.
7308 (which_symbols): Use it.
7310 2011-11-07 Kenichi Handa <handa@m17n.org>

7331 (window_box_width, window_box_left, window_box_left_offset)
7332 (window_box_right, window_box_right_offset): Declare extern.
7333 Otherwise, these inline functions do not conform to C99 and
7334 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7335 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7336 * intervals.c (adjust_intervals_for_insertion)
7337 (adjust_intervals_for_deletion): Now extern, because otherwise the
7338 extern inline functions 'offset_intervals' couldn't refer to it.
7339 (static_offset_intervals): Remove.
7340 (offset_intervals): Rewrite using the old contents of
7341 static_offset_intervals. The old version didn't conform to C99
7342 because an extern inline function contained a reference to an
7343 identifier with static linkage.

7365 (Fwindow_vscroll): Doc fix.
7366 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
7367 argument, since it makes no sense to pass a live window and for
7368 consistency with window-child.

7655 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7656 * editfns.c: Rewrite current-time-zone so that it invokes
7657 the equivalent of (format-time-string "%Z") to get the time zone name.
7658 This fixes a bug when the time zone name contains characters that
7659 need converting from the system time locale to Emacs internal format.
7660 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7661 that patch fixed format-time-string to do the conversion, but
7662 I forgot to fix current-time-zone.
7663 (format_time_string): New function, containing most of
7664 what Fformat_time_string used to contain.

7674 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7676 * xdisp.c (start_display): If the character at POS is displayed
7677 via a display vector, reset IT->current.dpvec_index to zero.
7678 (try_window_reusing_current_matrix): If a line ends in a display
7679 vector or the next line starts in a display vector, continue
7680 redrawing the window even though the character position of
7681 start_row was reached.

7686 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7687 with nobreak-char-display too.
7689 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7691 Fix part 3 of bug#9771.
7692 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7693 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7694 non-neutral characters if the current character is a paragraph
7695 separator (a.k.a. Newline). This avoids running the same
7696 expensive loop twice, once when we consume the preceding newline
7697 and the other time when the line actually needs to be displayed.
7698 Avoid the loop when we see neutrals on the base embedding level
7699 following a character whose directionality is the same as the
7700 paragraph's. This avoids running the expensive loop when a line
7701 ends in a long sequence of neutrals, like control characters.
7702 Add assertion against STRONG_AL type. Slightly rearrange code
7703 that determines the type of a neutral given the first non-neutral
7705 (bidi_level_of_next_char): Set next_en_pos to zero when
7706 invalidating its info.
7708 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7710 * xdisp.c (push_display_prop): Determine whether to record string
7711 or buffer position by IT->string, not by IT->method. Allow
7712 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7713 (move_it_vertically_backward): Don't look for character position
7714 immediately after the newline when in a continuation line.
7717 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7719 * window.c (coordinates_in_window): Rewrite and delabelize
7720 vertical border check. (Bug#5357) (Bug#9618)
7722 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7724 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7725 errors in XSetWindowBorder (bug#9310).
7727 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7729 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7730 avoid crash when xmalloc overrun checking is enabled.
7732 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7734 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7735 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7736 cursor motion with <left> and <right> arrow keys.
7738 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7739 some callers set that themselves.
7741 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7743 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7744 display string and the previous row comes from the same string and
7745 is empty. (Bug#9739) (Bug#9738)
7747 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7749 * doc.c (get_doc_string): Encode file name (bug#9735).
7751 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7753 * bidi.c (bidi_level_of_next_char):
7754 * xdisp.c (get_visually_first_element): Remove old incorrect
7755 comments regarding the Unicode Line Separator character.
7757 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7759 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7761 * alloc.c (Fgc_status): Do not access beyond zombies array
7762 boundary if nzombies > MAX_ZOMBIES.
7763 * alloc.c (dump_zombies): Add missing format specifier.
7765 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7767 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7768 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7770 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7771 Some packages use them to denote characters with modifiers.
7773 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7775 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7776 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7777 matching a pp-number. Rename parameter var to var1.
7779 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7781 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7783 2011-10-08 Glenn Morris <rgm@gnu.org>
7785 * callint.c (Fcall_interactively): Give a more explicit error for the
7786 'c' case with a non-character input. (Bug#8479)
7788 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7790 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7792 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7793 lines that are hscrolled on the left.
7795 * dispnew.c (buffer_posn_from_coords): Account for a possible
7796 presence of header-line. (Bug#4426)
7798 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7800 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7801 Don't advertise functionality which we discourage or doesn't work.
7803 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7805 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7806 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7807 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7808 this makes Emacs dump core during garbage collection on rare
7809 occasions. sizeof is obviously inferior to offsetof here, so
7810 stick with offsetof.
7811 (GC_POINTER_ALIGNMENT): New macro.
7812 (mark_memory): Omit 3rd (offset) arg; caller changed.
7813 Don't assume EMACS_INT alignment is the same as pointer alignment.
7815 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7817 * keyboard.c (read_key_sequence_remapped): New var.
7818 (read_key_sequence): Compute remapping in the right buffer.
7819 (command_loop_1): Use read_key_sequence's remapping directly.
7821 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7823 * dired.c (file_name_completion): Don't expand file name.
7824 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7825 before checking file name handler.
7827 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7828 they've been requested explicitly (bug#9591).
7830 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7832 * keymap.c (Fsingle_key_description): Use make_specified_string
7833 instead of build_string to build string from push_key_description.
7836 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7838 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7839 This fixes a Y2038 bug on 64-bit hosts.
7840 * buffer.c (reset_buffer):
7841 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7842 (Fclear_buffer_auto_save_failure):
7843 Use 0, not -1, to represent an unset failure time, since time_t
7844 might not be signed.
7846 Remove dependency on glibc malloc internals.
7847 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7848 Move back here from lisp.h, but with their new implementations.
7849 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7850 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7851 * charset.c (charset_table_init): New static var.
7852 (syms_of_charset): Use it instead of xmalloc. This removes a
7853 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7854 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7855 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7856 Move back to alloc.c.
7857 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7858 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7860 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7862 * nsterm.m (windowDidResize): Call x_set_window_size only when
7863 ns_in_resize is true. Otherwise set pixelwidth/height and
7864 call change_frame_size (Bug#9628).
7866 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7868 Port --enable-checking=all to Fedora 14 x86-64.
7869 * charset.c (syms_of_charset): Also account for glibc malloc's
7870 internal overhead when calculating the initial malloc maximum.
7872 Port --enable-checking=all to Fedora 14 x86.
7873 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7875 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7876 (overrun_check_realloc, overrun_check_free):
7877 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7878 That way, xmalloc returns a properly-aligned pointer even if
7879 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7880 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7881 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7882 into account when calculating the initial malloc maximum.
7883 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7884 Move here from alloc.c, so that charset.c can use it too.
7885 Properly align; the old code wasn't right for common 32-bit hosts
7886 when configured with --enable-checking=all.
7887 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7888 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7890 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7892 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7895 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7897 * xdisp.c (compute_display_string_end): If there's no display
7898 string at CHARPOS, return -1.
7900 * bidi.c (bidi_fetch_char): When compute_display_string_end
7901 returns a negative value, treat the character as a normal
7902 character not covered by a display string. (Bug#9624)
7904 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7906 * lread.c (Fread_from_string): Fix typo in docstring.
7908 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7910 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7911 newline, reseat the iterator instead of bidi-iterating there one
7912 character at a time. (Bug#9610)
7913 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7914 TO_CHARPOS if the bidi iterator is at base embedding level.
7916 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7918 * lread.c (readevalloop): Use correct code for NBSP.
7919 (read1): Likewise. (Bug#9608)
7921 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7923 * dbusbind.c (Fdbus_register_signal): When service is not
7924 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7926 2011-09-25 Glenn Morris <rgm@gnu.org>
7928 * buffer.c (truncate-lines): Doc fix.
7930 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7932 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7933 (Fset_window_next_buffers): Doc fix.
7935 2011-09-24 Glenn Morris <rgm@gnu.org>
7937 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7939 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7941 Fix minor problems found by static checking.
7942 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7943 * indent.c (Fvertical_motion): Fix == vs = typo.
7945 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7947 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7948 Default value is now t. Doc fix.
7950 * indent.c (Fvertical_motion): Compute and apply the overshoot
7951 logic when moving up, not only when moving down. Fix the
7952 confusing name and values of the it_overshoot_expected variable;
7953 logic changes accordingly. (Bug#9254) (Bug#9549)
7955 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7956 CHARPOS is covered by a display string which includes newlines.
7957 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7958 is covered by a display string with embedded newlines.
7960 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7962 * dbusbind.c (Fdbus_register_signal): Add match rule to
7963 Vdbus_registered_objects_table. (Bug#9581)
7964 (Fdbus_register_method, Vdbus_registered_objects_table):
7967 2011-09-24 Jim Meyering <meyering@redhat.com>
7969 do not ignore write error for any output size
7970 The previous change was incomplete.
7971 While it makes emacs --batch detect the vast majority of stdout
7972 write failures, errors were still ignored whenever the output size is
7973 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7974 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7975 && echo FAIL: ignored write error
7976 FAIL: ignored write error
7977 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7978 && echo FAIL: ignored write error
7979 FAIL: ignored write error
7980 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7982 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>

7985 non-successfully if a write error occurred on stdout. (Bug#9574)
7987 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7989 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7992 * dispextern.h (struct it): Update the comment documenting what
7995 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7997 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7998 a display string, extend search for cursor position to end of row.
7999 (find_row_edges): If the row ends in a newline from a display
8000 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
8001 Handle the case of a display string with multiple newlines.
8002 (Fcurrent_bidi_paragraph_direction): Fix search for previous
8003 non-empty line. Fixes confusing cursor motion with arrow keys at
8004 the beginning of a line that starts with whitespace.

8013 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
8016 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8018 * xdisp.c (display_line): Record maximum and minimum buffer
8019 positions even if no glyphs were produced (e.g., by a zero-width
8020 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
8021 buffer positions that will be removed from the glyph row because
8023 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
8024 column is beyond frame width: don't subtract 1 "pixel" when
8025 computing width of the stretch.
8026 (reseat_at_next_visible_line_start): Undo the change made on
8027 2011-09-17 that saved paragraph information and restored it after
8028 the call to `reseat'. (Bug#9545)
8030 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8032 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
8033 and turn window cursor on if cleared (Bug#9415).

8046 Fix minor problem found by static checking.
8047 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
8048 initialized, to pacify gcc -Wuninitialized.
8050 * fileio.c: Report proper errno when syscall falls.
8051 (Finsert_file_contents): Save and restore errno,
8052 so that report_file_error outputs the correct diagnostic.
8053 (Fwrite_region) [CLASH_DETECTION]: Likewise.
8055 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8057 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
8059 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8061 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
8062 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
8064 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8066 * xdisp.c (reseat_at_next_visible_line_start): Keep information
8067 about the current paragraph and restore it after the call to reseat.
8069 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
8070 (bidi_find_paragraph_start): Search back for paragraph beginning
8071 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
8072 (bidi_move_to_visually_next): Only trigger paragraph-related
8073 computations when the last character is a newline or at EOB, not
8074 just any NEUTRAL_B. (Bug#9470)
8076 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
8077 truncated lines if point is covered by a display string. (Bug#9524)
8079 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
8081 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8082 (cons_to_x_long): New function.
8083 (lisp_data_to_selection_data): Use it. Correct the test for
8084 short-versus-long data; it was negated. Break out of vector
8085 loop, for efficiency, when a long datum is discovered.
8087 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8089 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8091 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8093 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
8094 GCC PR/17406) by declaring this function with external scope.
8096 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

8117 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8118 This occurs when processing a multibyte format.
8119 Problem reported by Wolfgang Jenker.
8121 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8123 * xdisp.c (try_cursor_movement): Only check for exact match if
8124 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8126 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8128 Remove unused external symbols.
8129 * dispextern.h (calc_pixel_width_or_height): Remove decl.

8134 * xterm.c, xterm.h (x_catching_errors): Remove.
8136 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8138 * xselect.c: Use signed conversions more consistently (Bug#9498).
8139 (selection_data_to_lisp_data): Assume incoming selection data are
8140 signed integers, not unsigned. This is to be consistent with
8141 outgoing selection data, which was modified to use signed integers
8142 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8143 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8144 expects long, not unsigned long.

8148 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
8149 computation of loop end. Reported by Johan Bockgård

8159 rather than the other way around. (Bug#2496)
8161 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
8163 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
8165 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
8167 * minibuf.c (Fread_from_minibuffer): Doc fix.
8169 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8171 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8172 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8174 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8176 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8177 value for non-existent files.
8179 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8181 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8182 set its "size" to -1. This will set the modtime_size field of
8183 the corresponding buffer to -1, which is what
8184 verify-visited-file-modtime expects for files that do not exist.
8187 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8189 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8191 * lisp.h: ... from here. push_key_description is no longer
8192 defined in keyboard.c, so its declaration should not be in
8193 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8194 logically belongs with push_key_description.
8196 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8198 * buffer.h: Include <sys/types.h> instead of <time.h>.
8199 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8200 Problem reported by Herbert J. Skuhra.
8202 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8204 * xml.c (parse_region): Make the parsing work for
8205 non-comment-starting XML files again (bug#9144).
8207 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8209 * image.c (gif_load): Fix calculation of bottom and right corner.
8212 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8214 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8215 redisplay in small windows.
8217 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8219 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8221 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8223 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8224 Operate on live windows only.
8226 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8228 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8230 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8232 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8233 only under bidi iteration.
8235 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8237 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8239 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8241 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8242 Without this fix, the command to link temacs failed due to an
8243 undefined symbol __builtin_isnan. This is because
8244 /usr/include/iso/math_c99.h #defines isnan(x) to
8245 __builtin_isnan(x), but the bundled gcc, which identifies itself
8246 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8248 * floatfns.c (isnan): #undef, and then #define to a clone of
8250 (Fisnan): Always define, since it's always available now.
8251 (syms_of_floatfns): Always define isnan at the Lisp level.
8253 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8255 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8257 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8259 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8260 The previous code assumed that file offsets (off_t values) fit in
8261 EMACS_INT variables, which is not true on typical 32-bit hosts.
8262 The code messed up by falsely reporting buffer overflow in cases
8263 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8264 when "big" contains more than 2**29 bytes, even though this
8265 inserts just one byte and does not overflow the buffer.
8266 (Finsert_file_contents): Store file offsets as off_t
8267 values, not as EMACS_INT values. Check for overflow when
8268 converting between EMACS_INT and off_t. When checking for
8269 buffer overflow or for overlap, take the offsets into account.
8270 Don't use EMACS_INT for small values where int suffices.
8271 When checking for overlap, fix a typo: ZV was used where
8272 ZV_BYTE was intended.
8273 (Fwrite_region): Don't assume off_t fits into 'long'.
8274 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8276 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8278 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8280 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8282 sprintf-related integer and memory overflow issues (Bug#9412).
8284 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8285 (esprintf, exprintf, evxprintf): New functions.
8286 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8287 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8288 (modify_event_symbol): Do not assume that the length of
8289 name_alist_or_stem is safe to alloca and fits in int.
8290 (Fexecute_extended_command): Likewise for function name and binding.
8291 (Frecursion_depth): Wrap around reliably on integer overflow.
8292 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8293 since some callers pass EMACS_INT values.
8294 (Fsingle_key_description): Don't crash if symbol name contains more
8295 than MAX_ALLOCA bytes.
8296 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8297 (get_minibuffer): Arg is now EMACS_INT, not int.
8298 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8299 (esprintf, exprintf, evxprintf): New decls.
8300 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8302 * dbusbind.c (signature_cat): New function.
8303 (xd_signature, Fdbus_register_signal):
8304 Do not overrun buffer; instead, report string overflow.
8306 * dispnew.c (add_window_display_history): Don't overrun buffer.
8307 Truncate instead; this is OK since it's just a log.
8309 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8310 even if the time zone offset is outlandishly large.
8311 Don't mishandle offset == INT_MIN.
8313 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8314 when creating daemon; the previous buffer-overflow check was incorrect.
8316 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8317 which has the guts of the old verror function.
8319 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8320 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8322 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8323 (font_unparse_xlfd): Don't blindly alloca long strings.
8324 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8325 fits in int, when using sprintf. Use single snprintf to count
8326 length of string rather than counting it via multiple sprintfs;
8327 that's simpler and more reliable.
8328 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8329 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8330 sprintf, in case result does not fit in int.
8332 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8333 (fontset_from_font): Print it.
8335 * frame.c (tty_frame_count): Now printmax_t, not int.
8336 (make_terminal_frame, set_term_frame_name): Print it.
8337 (x_report_frame_params): In X, window IDs are unsigned long,
8338 not signed long, so print them as unsigned.
8339 (validate_x_resource_name): Check for implausibly long names,
8340 and don't assume name length fits in 'int'.
8341 (x_get_resource_string): Don't blindly alloca invocation name;
8342 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8345 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8346 (xg_check_special_colors, xg_set_geometry):
8347 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8349 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8350 Use esprintf, not sprintf, in case result does not fit in int.
8352 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8353 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8354 it as a large positive number.
8355 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8356 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8358 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8359 in case result does not fit in int.
8361 * print.c (float_to_string): Detect width overflow more reliably.
8362 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8363 buffer overrun. Don't assume list length fits in 'int'. Treat
8364 print length of 0 as 0, not as infinity; to be consistent with other
8365 uses of print length in this function. Don't overflow print length
8366 index. Don't assume hash table size fits in 'long', or that
8367 vectorlike size fits in 'unsigned long'.
8369 * process.c (make_process): Use printmax_t, not int, to format
8370 process-name gensyms.
8372 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8374 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8375 to avoid potential buffer overrun.
8377 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8378 if X resource line is longer than 512 bytes.
8380 * xfns.c (x_window): Make sprintf buffer a bit bigger
8381 to avoid potential buffer overrun.
8383 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8385 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8387 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8389 Integer overflow fixes for scrolling, etc.
8390 Without these, Emacs silently mishandles large integers sometimes.
8391 For example, "C-u 4294967297 M-x recenter" was treated as if
8392 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8394 * xdisp.c (try_window_id): Check Emacs fixnum range before
8395 converting to 'int'.
8397 * window.c (window_scroll_line_based, Frecenter):
8398 Check that an Emacs fixnum is in range before assigning it to 'int'.
8399 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8400 values converted from Emacs fixnums.
8401 (Frecenter): Don't wrap around a line count if it is out of 'int'
8402 range; instead, treat it as an extreme value.
8403 (Fset_window_configuration, compare_window_configurations):
8404 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8406 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8407 that can exceed INT_MAX. Check that EMACS_INT value is in range
8408 before assigning it to the (possibly-narrower) index.
8409 (match_limit): Don't assume that a fixnum can fit in 'int'.
8411 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8414 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8415 (Fvertical_motion): Don't wrap around LINES values that don't fit
8416 in 'int'. Instead, treat them as extreme values. This is good
8417 enough for windows, which can't have more than INT_MAX lines anyway.
8419 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8421 * Require libxml/parser.h to avoid compilation warning.
8423 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8425 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8426 since this reportedly can destroy thread storage.
8428 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8430 * syntax.c (find_defun_start): Update all cache variables if
8431 exiting early (Bug#9401).
8433 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8435 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8437 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8438 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8439 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8441 * term.c (tty_append_glyph): New function.
8442 (produce_stretch_glyph): Static function and its prototype deleted.
8444 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8447 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8449 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8450 when checking :margin (Bug#9390).
8451 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8452 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8453 so that the name doesn't mislead. All uses changed.
8455 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8457 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8460 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8462 * xdisp.c (move_it_to): Don't bail out early when reaching
8463 position beyond to_charpos, if we are scanning backwards.
8464 (move_it_vertically_backward): When DY == 0, make sure we get to
8465 the first character in the line after the newline.
8467 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8469 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8470 (ccl_driver): Do not generate an out-of-range pointer.
8471 (Fccl_execute_on_string): Remove unnecessary check for
8472 integer overflow, noted by Stefan Monnier in
8473 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8474 Remove a FIXME that didn't need fixing.
8475 Simplify the newly-introduced buffer reallocation code.
8477 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8479 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8481 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8483 Integer and memory overflow issues (Bug#9196).
8485 * doc.c (get_doc_string): Rework so that
8486 get_doc_string_buffer_size is the actual buffer size, rather than
8487 being 1 less than the actual buffer size; this makes xpalloc more
8490 * image.c (x_allocate_bitmap_record, cache_image):
8491 * xselect.c (Fx_register_dnd_atom):
8492 Simplify previous changes by using xpalloc.
8494 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8495 since either will do and ptrdiff_t is convenient with xpalloc.
8497 * charset.c (charset_table_size)
8498 (struct charset_sort_data.priority): Now ptrdiff_t.
8499 (charset_compare): Don't overflow if priorities differ greatly.
8500 (Fsort_charsets): Don't assume list length fits in int.
8501 Check for size-calculation overflow when allocating sort data.
8502 (syms_of_charset): Allocate an initial charset table that is
8503 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8505 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8507 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8508 The actual value is always <= INT_MAX, and leaving it unsigned made
8509 overflow checking harder.
8511 * dispextern.h (struct glyph_matrix.rows_allocated)
8512 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8513 with xpalloc. The values are still always <= INT_MAX.
8515 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8517 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8518 (SAFE_NALLOCA): New macro.
8520 * region-cache.c (struct boundary.pos, find_cache_boundary)
8521 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8522 (set_cache_region, invalidate_region_cache)
8523 (revalidate_region_cache, know_region_cache, region_cache_forward)
8524 (region_cache_backward, pp_cache):
8525 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8526 so that ptrdiff_t * can be passed to xpalloc.
8527 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8528 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8529 (pp_cache): Don't assume cache_len fits in int.
8530 * region-cache.h: Adjust extern decls to match.
8532 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8533 EMACS_INT, since either will do, for xpalloc.
8535 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8536 (xnmalloc, xnrealloc, xpalloc): New functions.
8538 * bidi.c (bidi_shelve_header_size): New constant.
8539 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8540 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8542 * bidi.c (bidi_cache_shrink):
8543 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8545 Don't update size of array until after memory allocation succeeds,
8546 because xmalloc/xrealloc may not return.
8547 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8548 now that we have proper integer overflow checking.
8549 (record_overlay_string, overlay_strings): Catch overflows when
8550 calculating size of overlay_str_buf.
8552 * callproc.c (Fcall_process): Check for size overflow when
8553 calculating size of args2.
8554 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8555 Normally we prefer signed values, but sticking with ptrdiff_t would
8556 require adding more-complicated checks.
8558 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8559 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8560 Redo buffer-overflow calculations to avoid integer overflow.
8561 Add a FIXME comment where memory seems to be over-allocated.
8563 * character.c (Fstring): Check for size-calculation overflow.
8565 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8566 unnecessary integer overflow. Check for size overflow.
8567 (encode_coding_object): Don't update size until xmalloc succeeds.
8569 * composite.c (get_composition_id): Check for overflow in glyph
8570 length calculations.
8572 Integer and memory overflow fixes for display code.
8573 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8574 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8575 (scrolling_window): Check for overflow in size calculations.
8576 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8577 Don't assume glyph table len fits in int.
8578 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8579 (row_table_size): Now ptrdiff_t, not int.
8580 (scrolling_window): Avoid overflow in size calculations.
8581 Don't update size until allocation succeeds.
8582 * fns.c (concat): Check for overflow in size calculations.
8583 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8584 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8585 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8587 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8588 (get_doc_string): Check for size calculation overflow.
8589 Don't update size until allocation succeeds.
8590 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8591 EMACS_INT, where ptrdiff_t will do.
8592 (Fsubstitute_command_keys): Check for string overflow.
8594 * editfns.c (set_time_zone_rule): Don't assume environment length
8596 (message_length): Now ptrdiff_t, not int.
8597 (Fmessage_box): Don't update size until allocation succeeds.
8598 Don't assume message length fits in int.
8599 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8601 * emacs.c (main): Do not reallocate argv, since there is a null at
8602 the end that can be overwritten, and this way there's no need to
8603 worry about size-calculation overflow.
8604 (sort_args): Check for size-calculation overflow.
8606 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8608 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8610 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8611 (x_set_scroll_bar_width, x_figure_window_size):
8612 Check for integer overflow.
8613 (x_set_alpha): Do not assume XINT fits in int.
8615 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8616 This is for the members text_lines, text_cols, total_lines, total_cols,
8617 where the system imposes an 'int' limit.
8619 * fringe.c (Fdefine_fringe_bitmap):
8620 Don't update size until alloc works.
8622 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8623 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8625 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8626 Check for size-calculation overflow.
8627 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8628 do, as we prefer signed integers.
8629 (id_to_widget.max_size, id_to_widget.used)

8682 (Fset_match_data): Don't assume list lengths fit in 'int'.
8684 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,

8732 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8733 (X_LONG_MIN): New macros.
8734 Use them to make the following changes clearer.
8735 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8736 This change doesn't affect the value now, but it may help remind
8737 future maintainers not to raise the value too much later.
8738 (SELECTION_QUANTUM): Remove, replacing with ...
8739 (selection_quantum): ... new function, which avoids overflow.
8741 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

8759 Don't store size until memory allocation succeeds.
8760 (x_get_window_property): Plug memory leak on memory exhaustion.
8761 Don't double-block input; malloc is safe here. Don't assume 2**34
8762 - 4 fits in unsigned long. Add an xassert to check
8763 XGetWindowProperty overflow. Be more careful about overflow
8764 calculations, and distinguish size from memory overflow better.

8770 in the range -65535 through -1 fit in an X unsigned short.
8771 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8772 result parameters unless successful. Rely on cons_to_unsigned
8773 to report problems with elements; the old code wasn't right anyway.
8774 (x_check_property_data): Check for int overflow; we cannot use
8775 a wider type due to X limits.

8808 * lisp.h (hash_lookup, hash_put):
8809 * minibuf.c (Ftest_completion):
8810 Use ptrdiff_t for hash table indexes, not int (which is too
8811 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8812 32-bit --with-wide-int hosts).

8845 (x_send_scroll_bar_event): Likewise. Check that the size does not
8846 exceed limits imposed by XClientMessageEvent, as well as the usual
8847 ptrdiff_t and size_t limits.
8849 * keyboard.c: Overflow, signedness and related fixes.
8850 (make_lispy_movement): Use same integer type in forward decl
8851 that is used in the definition.
8852 (read_key_sequence, keyremap_step):
8853 Change bufsize argument back to int, undoing my 2011-03-30 change.
8854 We prefer signed types, and int is wide enough here.
8855 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8856 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8857 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8858 length, not size_t. Use ptrdiff_t for index, not int.
8859 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8860 possibility of integer overflow.

8886 since parse_image_check makes sure they fit into int.
8887 (png_load, gif_load, svg_load_image):
8888 Prefer int to unsigned where either will do.
8889 (tiff_handler): New function, combining the cores of the
8890 old tiff_error_handler and tiff_warning_handler.
8891 This function is rewritten to use vsnprintf and thereby avoid
8892 stack buffer overflows. It uses only the features of vsnprintf
8893 that are common to both POSIX and native Microsoft.
8894 (tiff_error_handler, tiff_warning_handler): Use it.
8895 (tiff_load, gif_load, imagemagick_load_image):

8899 the integer types that MagickCropImage accepts. Don't assume
8900 Vimagemagick_render_type has a nonnegative value. Don't assume
8901 size_t fits in 'long'.
8902 (gs_load): Use printmax_t to print the widest integers possible.

8920 accurately, and prefer exact match for point under bidi.
8921 Don't advance `row' beyond the last row of the window.
8923 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8924 into disp_prop; all users changed.

8942 positioning on the newline at EOL of R2L text within L2R
8943 paragraph, and vice versa.
8944 (try_cursor_movement): Check continued rows, in addition to
8945 continuation rows. Fixes unwarranted scroll when point enters a
8946 continued line of R2L text within an L2R paragraph, or vice versa.
8947 (cursor_row_p): Consider the case of point being equal to
8948 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8949 from the end of a short line to the beginning of a continued line

8977 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8978 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8979 candidate is selected by the mouse, and that candidate has a
8980 composed character under the mouse.
8982 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8983 coordinates reported by pos-visible-in-window-p for a composed

8998 * image.c (gif_load): Don't assume that each subimage has the same
8999 dimensions as the base image. Handle disposal method that is
9000 "undefined" by the gif spec (Bug#9335).
9002 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
9004 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

9009 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
9010 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
9011 from an Org mode buffer to a Speedbar frame.
9013 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
9014 a composition, take its buffer position from IT->cmp_it.charpos.
9015 Fixes cursor positioning at the beginning of a line that begins
9016 with a composed character.
9018 2011-08-18 Eli Zaretskii <eliz@gnu.org>
9020 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
9021 character bidirectional type, use STRONG_L instead. Fixes crashes
9022 in a buffer produced by `describe-categories'.
9024 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
9025 members before the level stack, so they would be saved and
9026 restored when copying iterator state. Fixes incorrect reordering
9027 around TABs covered by display properties.
9029 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

9094 2011-08-14 Kenichi Handa <handa@m17n.org>
9096 * process.c (create_process): Call setup_process_coding_systems
9097 after the pid of the process is set to -1 (Bug#8162).
9099 2011-08-14 Eli Zaretskii <eliz@gnu.org>
9101 * xdisp.c (move_it_in_display_line_to): Don't invoke
9102 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
9103 ppos_it. Fixes vertical cursor motion when line beginning is
9104 covered by an image. (Bug#9296)
9106 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
9108 * nsterm.h (ns_run_ascript): Declare.
9109 (NSAPP_DATA2_RUNASSCRIPT): Define.
9111 * nsfns.m (as_script, as_result, as_status): New static variables.
9112 (ns_run_ascript): New function.
9113 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
9114 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
9115 the event loop. Get status from as_status (Bug#7276).
9117 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9118 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
9119 the event loop (Bug#7276).
9121 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
9123 * gnutls.c (QCgnutls_bootprop_priority)
9124 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
9125 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
9126 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
9127 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
9128 (QCgnutls_bootprop_verify_hostname_error)
9129 (QCgnutls_bootprop_callbacks_verify): Rename from
9130 Qgnutls_bootprop_..., all uses changed.
9132 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
9135 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
9137 * xfaces.c (Qframe_set_background_mode): Now static.
9138 * dispextern.h (Qframe_set_background_mode): Remove decl.
9140 * process.c (Fnetwork_interface_info): Declare local only if needed.
9142 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
9144 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
9145 (Fnetwork_interface_list): Allocate in increments of bytes instead
9146 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
9147 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
9149 (struct ifflag_def): notrailers is smart on OSX.
9150 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9151 Get hardware address with getifaddrs if available.
9153 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9155 * xdisp.c (iterate_out_of_display_property): xassert that
9156 IT->position is set to within IT->object's boundaries. Break from
9157 the loop as soon as EOB is reached; avoids infloops in redisplay
9158 when IT->position is set up wrongly due to some bug.
9159 Set IT->current to match the bidi iterator unconditionally.
9160 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9161 entry. Force push_it to save on the stack the current
9162 buffer/string position, to be restored by pop_it. Fix flags in
9163 the iterator structure wrt the object coming from a display
9164 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9165 properties. (Bug#9284)
9167 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9169 * fontset.c (fontset_get_font_group): Add proper type checks.
9172 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

9175 and LC_VERSION_MIN_MACOSX.
9176 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
9177 (dump_it) [LC_FUNCTION_STARTS]: Use it.
9179 2011-08-08 Eli Zaretskii <eliz@gnu.org>
9181 * xdisp.c (forward_to_next_line_start): Allow to use the
9182 no-display-properties-and-no-overlays under bidi display.
9183 Set disp_pos in the bidi iterator to avoid searches for display
9184 properties and overlays.
9186 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9188 * editfns.c (Fset_time_zone_rule): Document relationship with the
9191 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9192 the font entity extracted from the cache (Bug#8109).
9194 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9196 * composite.c (autocmp_chars): Don't reset point. That is done by
9197 restore_point_unwind (Bug#5984).
9199 2011-08-07 Juri Linkov <juri@jurta.org>
9201 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9202 to show the arg `TIME' instead of `TIMEVAL'.
9204 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9206 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9207 display property strides EOL and includes a newline, as in
9208 longlines-mode. (Bug#9254)
9209 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9210 word-wrap under bidirectional display. (Bug#9224)
9212 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9213 is non-zero, even if the data buffer is NULL. Fixes a crash in
9214 vertical-motion with longlines-mode. (Bug#9254)
9216 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9218 * bidi.c <bidi_cache_total_alloc>: Now static.
9219 (bidi_initialize): Initialize bidi_cache_total_alloc.
9221 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9224 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9225 amount allocated this far in `bidi_cache_total_alloc'.
9226 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9227 non-zero, only free the data buffer without restoring the cache
9228 contents. All callers changed.
9230 * dispextern.h (bidi_unshelve_cache): Update prototype.
9232 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9233 (move_it_in_display_line, move_it_to)
9234 (move_it_vertically_backward, move_it_by_lines): Replace the call
9235 to xfree to an equivalent call to bidi_unshelve_cache.
9236 (move_it_in_display_line_to): Fix logic of returning
9237 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9239 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9241 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9242 came from a string character with a `cursor' property. (Bug#9229)
9244 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9246 * Makefile.in (LIB_PTHREAD): New variable.
9247 (LIBES): Add LIB_PTHREAD (Bug#9216).
9249 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9250 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9252 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9254 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9256 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9258 * xterm.c (x_find_topmost_parent): New function.
9259 (x_set_frame_alpha): Find topmost parent window with
9260 x_find_topmost_parent and set the property there also (bug#9181).
9261 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9263 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9265 * callproc.c (Fcall_process): Avoid vfork clobbering
9266 the local vars buffer, coding_systems, current_dir.
9268 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9270 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9272 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9274 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9275 so that it is not optimized away.
9277 * xdisp.c (compute_display_string_pos): Remove unused local.
9279 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9281 Fix slow cursor motion and scrolling in large buffers with
9282 selective display, like Org Mode buffers. (Bug#9218)
9284 * dispextern.h (struct bidi_it): New member disp_prop_p.
9286 * xdisp.c: Remove one-slot cache of display string positions.
9287 (compute_display_string_pos): Accept an additional argument
9288 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9289 for a display string or property. If found, set DISP_PROP_P
9292 * bidi.c (bidi_fetch_char): Accept an additional argument
9293 DISP_PROP_P, and pass it to compute_display_string_pos.
9294 Only handle text covered by a display string if DISP_PROP_P is returned
9295 non-zero. All callers of bidi_fetch_char changed.
9297 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9299 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9301 2010-12-03 Don March <don@ohspite.net>
9303 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9304 last character M-[char] is translated to ESC [char] (bug#7541).
9306 2011-08-02 Kenichi Handa <handa@m17n.org>
9308 * lisp.h (uniprop_table): Extern it.
9310 * chartab.c (uniprop_table): Make it non-static.
9312 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9314 * xdisp.c (forward_to_next_line_start): Accept additional argument
9315 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9317 (reseat_at_next_visible_line_start): Use the bidi iterator state
9318 returned by forward_to_next_line_start to restore the state of
9319 it->bidi_it after backing up to previous newline. (Bug#9212)
9321 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9323 * regex.c (re_comp): Protoize.
9324 (re_exec): Fix return type.
9325 (regexec): Fix type of `ret'. (Bug#9203)
9327 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9329 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9330 This is needed if max-image-size is a floating-point number.
9332 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9334 * print.c (print_object): Print empty symbol as ##.
9336 * lread.c (read1): Read ## as empty symbol.
9338 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9340 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9341 setting frame foreground color (Bug#9175).
9342 (x_set_background_color): Likewise.
9344 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9345 contents (Bug#9176).
9346 (EmacsTooltip -init): Remove bezels and add shadows to
9349 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9350 or scroll bar (Bug#8470).
9352 * nsfont.m (nsfont_open): Remove assignment to voffset and
9353 unnecessary vars hshink, expand, hd, full_height, min_height.
9354 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9356 * nsterm.h (nsfont_info): Remove voffset field.
9358 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9360 Implement strike-through and overline on NextStep (Bug#8863).
9362 * nsfont.m (nsfont_open): Use underline position provided by font,
9363 instead of hard-coded value of 2.
9364 (nsfont_draw): Call ns_draw_text_decoration instead.
9366 * nsterm.h: Add declaration for ns_draw_text_decoration.
9368 * nsterm.m (ns_draw_text_decoration): New function for drawing
9369 underline, overline, and strike-through.
9370 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9371 ns_draw_text_decoration. Change treatment of cursor drawing to
9372 accommodate underlining, etc.
9374 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9376 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9379 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9381 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9382 Without this fix, if a signal arrives just after memory fills up,
9383 'malloc' might be invoked reentrantly.
9385 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9386 In other words, assume that every image size is allowed, on non-X
9387 hosts. This assumption is probably wrong, but it lets Emacs compile.
9389 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9391 * regex.c (re_iswctype): Convert return values to boolean.
9393 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9395 * xdisp.c (compute_display_string_pos): Don't use cached display
9396 string position if the buffer had its restriction changed.
9399 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9401 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9403 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9405 Integer signedness and overflow and related fixes. (Bug#9079)
9407 * bidi.c: Integer size and overflow fixes.
9408 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9409 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9410 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9411 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9412 (bidi_find_other_level_edge):
9413 Use ptrdiff_t instead of EMACS_INT where either will do.
9414 This works better on 32-bit hosts configured --with-wide-int.
9415 (bidi_cache_ensure_space): Check for size-calculation overflow.
9416 Use % rather than repeated addition, for better worst-case speed.
9417 Don't set bidi_cache_size until after xrealloc returns, because it
9419 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9420 (bidi_cache_ensure_space): Also check that the bidi cache size
9421 does not exceed that of the largest Lisp string or buffer. See Eli
9422 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9424 * alloc.c (__malloc_size_t): Remove.
9425 All uses replaced by size_t. See Andreas Schwab's note
9426 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9428 * image.c: Improve checking for integer overflow.
9429 (check_image_size): Assume that f is nonnull, since
9430 it is always nonnull in practice. This is one less thing to
9431 worry about when checking for integer overflow later.
9432 (x_check_image_size): New function, which checks for integer
9433 overflow issues inside X.
9434 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9435 This removes the need for a memory_full check.
9436 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9437 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9438 (xbm_read_bitmap_data): Change locals back to 'int', since
9439 their values must fit in 'int'.
9440 (xpm_load_image, png_load, tiff_load):
9441 Invoke x_create_x_image_and_pixmap earlier,
9442 to avoid much needless work if the image is too large.
9443 (tiff_load): Treat overly large images as if
9444 x_create_x_image_and_pixmap failed, not as malloc failures.
9445 (gs_load): Use x_check_image_size.
9447 * gtkutil.c: Omit integer casts.
9448 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9449 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9451 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9453 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9454 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9455 would wrongly return t on a 64-bit host.
9457 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9458 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9459 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9460 and therefore cause GCC to emit a bogus diagnostic in some cases.
9462 * image.c: Integer signedness and overflow and related fixes.
9463 This is not an exhaustive set of fixes, but it's time to
9464 record what I've got.
9465 (lookup_pixel_color, check_image_size): Remove redundant decls.
9466 (check_image_size): Don't assume that arbitrary EMACS_INT values
9467 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9468 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9469 (tiff_load, imagemagick_load_image):
9470 Check for overflow in size calculations.
9471 (x_create_x_image_and_pixmap): Remove unnecessary test for
9472 xmalloc returning NULL; that can't happen.
9473 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9474 (xpm_color_bucket): Use better integer hashing function.
9475 (xpm_cache_color): Don't possibly over-allocate memory.
9476 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9477 (gif_memory_source):
9478 Use ptrdiff_t, not int or size_t, to record sizes.
9479 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9480 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9481 either works, as we prefer signed integers.
9482 (tiff_read_from_memory, tiff_write_from_memory):
9483 Return tsize_t, not size_t, since that's what the TIFF API wants.
9484 (tiff_read_from_memory): Don't fail simply because the read would
9485 go past EOF; instead, return a short read.
9486 (tiff_load): Omit no-longer-needed casts.
9487 (Fimagemagick_types): Don't assume size fits into 'int'.
9489 Improve hashing quality when configured --with-wide-int.
9490 * fns.c (hash_string): New function, taken from sxhash_string.
9491 Do not discard information about ASCII character case; this
9492 discarding is no longer needed.
9493 (sxhash-string): Use it. Change sig to match it. Caller changed.
9494 * lisp.h: Declare it.
9495 * lread.c (hash_string): Remove, since we now use fns.c's version.
9496 The fns.c version returns a wider integer if --with-wide-int is
9497 specified, so this should help the quality of the hashing a bit.
9499 * emacs.c: Integer overflow minor fix.
9500 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9501 Define only if GNU_LINUX.
9502 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9504 * dispnew.c: Integer signedness and overflow fixes.
9505 Remove unnecessary forward decls, that were a maintenance hassle.
9506 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9508 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9509 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9510 (prepare_desired_row, line_draw_cost):
9511 Use int, not unsigned, where either works.
9512 (save_current_matrix, restore_current_matrix):
9513 Use ptrdiff_t, not size_t, where either works.
9514 (init_display): Check for overflow more accurately, and without
9515 relying on undefined behavior.
9517 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9518 Remove, replacing with the new symbols in lisp.h. All uses changed.
9519 * fileio.c (make_temp_name):
9520 * filelock.c (lock_file_1, lock_file):
9521 * xdisp.c (message_dolog):
9522 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9523 Use pMd etc. instead.
9524 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9525 replacing the pWIDE etc. symbols removed from editfns.c.
9527 * keyboard.h (num_input_events): Now uintmax_t.
9528 This is (very slightly) less likely to mess up due to wraparound.
9531 * buffer.c: Integer signedness fixes.
9532 (alloc_buffer_text, enlarge_buffer_text):
9533 Use ptrdiff_t rather than size_t when either will do, as we prefer
9536 * alloc.c: Integer signedness and overflow fixes.
9537 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9538 (__malloc_size_t): Default to size_t, not to int.
9539 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9540 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9541 Prefer ptrdiff_t to size_t when either would do, as we prefer
9543 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9544 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9545 Now const. Initialize with values that are in range even if char
9547 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9548 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9549 These functions do the right thing with sizes > 2**32.
9550 (check_depth): Now ptrdiff_t, not int.
9551 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9552 Adjust to new way of storing sizes. Check for size overflow bugs
9554 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9555 slightly wrong anyway, as it missed one instance of
9556 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9557 (refill_memory_reserve): Omit needless cast to size_t.
9558 (mark_object_loop_halt): Mark as externally visible.
9560 * xselect.c: Integer signedness and overflow fixes.
9561 (Fx_register_dnd_atom, x_handle_dnd_message):
9562 Use ptrdiff_t, not size_t, since we prefer signed.
9563 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9564 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9565 x_dnd_atoms_size and x_dnd_atoms_length.
9567 * doprnt.c: Prefer signed to unsigned when either works.
9569 * doprnt.c (doprnt):
9571 * xdisp.c (vmessage):
9572 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9573 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9574 prefer signed arithmetic to avoid comparison confusion.
9575 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9576 but is a bit tricky.
9578 Assume freestanding C89 headers, string.h, stdlib.h.
9579 * data.c, doprnt.c, floatfns.c, print.c:
9580 Include float.h unconditionally.
9581 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9582 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9583 * regex.c: Likewise for stddef.h, string.h.
9584 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9585 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9586 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9587 (STDC_HEADERS): Remove obsolete defines.
9588 * sysdep.c: Include limits.h unconditionally.
9590 Assume support for memcmp, memcpy, memmove, memset.
9591 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9592 * regex.c (memcmp, memcpy):
9593 Remove; we assume C89 now.
9595 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9596 (__malloc_safe_bcopy): Remove; no longer needed.
9598 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9599 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9600 well either way, and we prefer signed to unsigned.
9602 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9604 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9605 closes the connection while we're reading (bug#9182).
9607 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9609 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9610 are specified (Bug#9168).
9612 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9614 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9615 Found by GCC static checking and --with-wide-int on a 32-bit host.
9617 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9619 * xdisp.c (compute_display_string_pos): Fix logic of caching
9620 previous display string position. Initialize cached_prev_pos to
9621 -1. Fixes slow-down at the beginning of a buffer.
9623 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9625 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9626 for attrs[LFACE_FONTSET_INDEX].
9628 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9630 * xml.c (parse_region): Remove unused local
9631 that was recently introduced.
9633 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9635 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9636 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9638 * xdisp.c (move_it_in_display_line_to): Record the best matching
9639 position for TO_CHARPOS while scanning the line, and restore it on
9640 exit if none of the characters scanned was an exact match.
9641 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9642 when exact match is impossible due to invisible text, and the
9643 lines are truncated.
9645 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9647 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9650 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9652 Fix a significant slow-down of cursor motion with C-n, C-p,
9653 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9654 auto-repeat under bidi redisplay in fontified buffers.
9655 * xdisp.c (compute_stop_pos_backwards): New function.
9656 (next_element_from_buffer): Call compute_stop_pos_backwards to
9657 find a suitable prev_stop when we find ourselves before
9659 (reseat): Don't look for prev_stop, as that could mean a very long
9661 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9662 <cached_disp_overlay_modiff>: Cache for last found display string
9664 (compute_display_string_pos): Return the cached position if asked
9665 about the same buffer in the same area of character positions, and
9666 the buffer wasn't changed since the time the display string
9667 position was cached.
9669 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9671 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9672 is an integer, which is important for empty lines. (Bug#9149)
9674 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9676 * frame.c (Fmodify_frame_parameters): In tty case, update the
9677 default face if necessary (Bug#4238).
9679 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9681 * editfns.c (Fstring_to_char): No need to explain what a character
9682 is in the docstring (Bug#6576).
9684 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9686 * xml.c (parse_region): Make sure we always return a tree.
9688 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9690 * xml.c (parse_region): If a document contains only comments,
9693 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9695 * xml.c (make_dom): Return comments, too.
9697 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9700 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9701 and the surrounding thread.
9702 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9703 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9704 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9706 * s/openbsd.h (BROKEN_SIGIO): Define.
9707 * unexelf.c (unexec) [__OpenBSD__]:
9708 Don't update the .mdebug section of the Alpha COFF symbol table.
9710 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9712 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9715 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9717 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9718 This fixes some race conditions on the permissions of any newly
9721 * alloc.c (valid_pointer_p): Use pipe, not open.
9722 This fixes some permissions issues when debugging.
9724 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9725 If fchown fails to set both uid and gid, try to set just gid,
9726 as that is sometimes allowed. Adjust the file's mode to eliminate
9727 setuid or setgid bits that are inappropriate if fchown fails.
9729 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9731 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9732 to compare Lisp_Objects.
9733 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9734 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9735 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9737 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9739 * lread.c (read_integer): Unread even EOF character.
9740 (read1): Likewise. Properly record start position of symbol.
9742 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9743 symbol character follows.
9745 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9747 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9748 This works around a problem with the previous change to Fcopy_file.
9749 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9750 and without this change, GCC might complain about discarding
9751 fchown's return value.
9753 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9755 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9757 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9759 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9761 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9763 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9764 it's used from the C level.
9766 * process.c: Use the same condition for POLL_FOR_INPUT in both
9767 keyboard.c and process.c (bug#1858).
9769 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9771 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9772 (Fgnutls_boot): Use it.
9774 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9776 * doc.c (Fsubstitute_command_keys): Revert last change.
9778 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9780 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9781 quotes the next character, and doesn't affect other longer
9782 sequences (bug#8935).
9784 * lread.c (syms_of_lread): Clarify that is isn't only
9785 `eval-buffer' and `eval-defun' that's affected by
9786 `lexical-binding' (bug#8460).
9788 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9790 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9791 bidi redisplay when a line includes both an image and is truncated.
9793 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9795 Fix minor problems found by static checking.
9796 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9797 (elsz): Now a signed constant, not a size_t var. We prefer signed
9798 types to unsigned, to avoid integer comparison confusion. Without
9799 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9800 "cannot optimize loop, the loop counter may overflow", a symptom
9802 * indent.c (Fvertical_motion): Mark locals as initialized.
9803 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9805 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9807 * search.c (Fre_search_backward): Mention `case-fold-search' in
9808 all the re_search_* functions (bug#8138).
9810 * keyboard.c (Fopen_dribble_file): Document when the file is

9820 (compute_display_string_end): Accept additional argument STRING.
9821 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
9822 (reseat_to_string): Initialize bidi_it->string.s and
9823 bidi_it->string.schars.
9824 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
9825 NULL (avoids a crash in bidi_paragraph_init).
9826 Initialize itb.string.lstring.
9827 (init_iterator): Call bidi_init_it only of a valid
9828 buffer position was specified. Initialize paragraph_embedding to
9830 (reseat_to_string): Initialize the bidi iterator.
9831 (display_string): If we need to ignore text properties of
9832 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9833 original value of -1 will not work with bidi.)
9834 (compute_display_string_pos): First arg is now struct
9835 `text_pos *'; all callers changed. Support display properties on
9837 (compute_display_string_end): Support display properties on Lisp
9839 (init_iterator, reseat_1, reseat_to_string): Initialize the
9840 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9841 when iterating on a string not from display properties).
9842 (compute_display_string_pos, compute_display_string_end):
9843 Fix calculation of the object to scan. Fixes an error when using
9845 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9846 base_level_stop; instead, set base_level_stop to BEGV.
9847 Fixes crashes in vertical-motion.
9848 (next_element_from_buffer): Improve commentary for when
9849 the iterator is before prev_stop.
9850 (init_iterator): Initialize bidi_p from the default value of
9851 bidi-display-reordering, not from buffer-local value. Use the
9852 buffer-local value only if initializing for buffer iteration.
9853 (handle_invisible_prop): Support invisible properties on strings
9854 that are being bidi-reordered.
9855 (set_iterator_to_next): Support bidi reordering of C strings and
9857 (next_element_from_string): Support bidi reordering of Lisp
9859 (handle_stop_backwards): Support Lisp strings as well.
9860 (display_string): Support display of R2L glyph rows.
9861 Use IT_STRING_CHARPOS when displaying from a Lisp string.
9862 (init_iterator): Don't initialize it->bidi_p for strings
9864 (reseat_to_string): Initialize it->bidi_p for strings here.
9865 (next_element_from_string, next_element_from_c_string)
9866 (next_element_from_buffer): Add xassert's for correspondence
9867 between IT's object being iterated and it->bidi_it.string
9869 (face_before_or_after_it_pos): Support bidi iteration.

9871 character that is not the first one in the visual order.
9872 (get_visually_first_element): New function, refactored from common
9873 parts of next_element_from_buffer, next_element_from_string, and
9874 next_element_from_c_string.
9875 (tool_bar_lines_needed, redisplay_tool_bar)
9876 (display_menu_bar): Force left-to-right direction. Add a FIXME
9877 comment for making that be controlled by a user option.

9879 bidi iterator. Save and restore the bidi_p flag.
9880 (pop_it): Iterate out of display property for string iteration as
9882 (iterate_out_of_display_property): Support iteration over strings.
9883 (handle_single_display_spec): Set up it->bidi_it for iteration
9884 over a display string, and call bidi_init_it.

9887 iterator for displaying display or overlay strings.
9888 (forward_to_next_line_start): Don't use the shortcut if
9890 (back_to_previous_visible_line_start): If handle_display_prop
9891 pushed the iterator stack, restore the internal state of the bidi
9892 iterator by calling bidi_pop_it same number of times.
9893 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9894 and we are bidi-iterating, don't decrement the iterator position;
9895 instead, set the first_elt flag in the bidi iterator, to produce
9897 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9898 (push_display_prop): xassert that we are iterating a buffer.
9899 (push_it, pop_it): Save and restore paragraph_embedding member.
9900 (handle_single_display_spec, next_overlay_string)

9902 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9903 correctly. Don't assume unibyte strings are not bidi-reordered.
9904 (compute_display_string_pos)
9905 (compute_display_string_end): Fix handling the case of C string.
9906 (push_it, pop_it): Save and restore from_disp_prop_p.
9907 (handle_single_display_spec, push_display_prop): Set the
9908 from_disp_prop_p flag.
9909 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

9913 for verifying that the iterator position is in sync with the bidi
9915 (handle_single_display_spec, get_overlay_strings_1)
9916 (push_display_prop): Fix initialization of paragraph direction for
9917 string when that of the parent object is not yet determined.

9919 iterator with IT's position. (Bug#7616)
9920 (find_row_edges): If ROW->start.pos gives position
9921 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

9930 saving a temporary copy of the iterator and restoring it back.
9931 (back_to_previous_visible_line_start, reseat_1)
9932 (init_iterator): Empty the bidi cache "stack".
9933 (move_it_in_display_line_to): If iterator ended up at
9934 EOL, but we never saw any buffer positions smaller than
9935 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9936 motion in bidi-reordered lines.
9937 (move_it_in_display_line_to): Record prev_method and prev_pos
9938 immediately before the call to set_iterator_to_next. Fixes cursor

9940 displayed in margins. (Bug#8133) (Bug#8867)
9941 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9943 (pos_visible_p): Support positions in bidi-reordered lines.
9944 Save and restore bidi cache.
9946 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9947 (bidi_paragraph_info): Delete unused struct.
9948 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9949 (bidi_cache_start): New variable.
9950 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

9955 (bidi_level_of_next_char, bidi_find_other_level_edge)
9956 (bidi_move_to_visually_next): Compare cache index with
9957 bidi_cache_start rather than with zero.
9958 (bidi_fetch_char): Accept new argument STRING; all callers
9959 changed. Support iteration over a string. Support strings with
9960 display properties. Support unibyte strings. Fix the type of
9961 `len' according to what STRING_CHAR_AND_LENGTH expects.
9962 (bidi_paragraph_init, bidi_resolve_explicit_1)
9963 (bidi_resolve_explicit, bidi_resolve_weak)

9974 initialized to valid values.
9975 (bidi_init_it): Don't initialize charpos and bytepos with invalid
9977 (bidi_level_of_next_char): Allow the sentinel "position" to pass
9978 the test for valid cached positions. Fix the logic for looking up
9979 the sentinel state in the cache. GCPRO the Lisp string we are
9981 (bidi_push_it, bidi_pop_it): New functions.
9982 (bidi_initialize): Initialize the bidi cache start stack pointer.
9983 (bidi_cache_ensure_space): New function, refactored from part of

10059 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
10060 The old code sometimes used this field without initializing it.
10062 * alloc.c (gc_sweep): Don't read past end of array.
10063 In theory, the old code could also have corrupted Emacs internals,
10064 though it'd be very unlikely.

10329 This isn't true in general, and it's particularly not true
10330 if Emacs is configured with --with-wide-int.
10331 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

10368 Random fixes. E.g., (random) never returned negative values.
10369 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10370 subseconds part to the entropy, as that's a bit more random.
10371 Prefer signed to unsigned, since the signedness doesn't matter and
10372 in general we prefer signed. When given a limit, use a
10373 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10374 latter isn't right if USE_2_TAGS_FOR_INTS.
10375 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10376 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10388 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
10389 This is more efficient than Ffile_directory_p and avoids a minor race.
10391 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
10393 * buffer.c (Foverlay_put): Say what the return value is
10396 * fileio.c (barf_or_query_if_file_exists): Check first if the file
10397 is a directory before asking whether to use the file name
10399 (barf_or_query_if_file_exists): Make the "File is a directory"
10400 error be more correct.
10402 * fns.c (Frequire): Remove the mention of the .gz files, since
10403 that's installation-specific, but keep the mention of

10416 Qgnutls_bootprop_verify_error (which is no longer used).
10418 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
10419 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
10420 Also (re)move comments that are misplaced or no longer relevant.

10445 leave any prefix arg for the up event (Bug#1586).
10447 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
10449 * lread.c (syms_of_lread): Mention single symbols defined by
10450 `defvar' or `defconst' (bug#7154).
10452 * fns.c (Frequire): Mention .el.gz files (bug#7314).

10521 * eval.c (struct backtrace): Simplify and port the data structure.
10522 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10523 signed bit field, as this assumption is not portable and it makes
10524 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10525 "char debug_on_exit : 1" as this is not portable either; instead,
10526 use the portable "unsigned int debug_on_exit : 1". Remove unused
10527 member evalargs. Remove obsolete comments about cc bombing out.

10717 (read1): Check for integer overflow in radices, and in
10718 read-circle numbers.

10762 on undefined behavior with wrong number of arguments.
10763 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10764 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10765 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10766 since we're not interested in debugging glyphs with old libraries.
10767 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10768 GCC 4.6.0's static checking.

10810 (x_session_initialize): Do not assume string length fits in int.
10812 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

10861 Use memcpy, not strncpy, where memcpy is what is really wanted.
10862 Don't assume (via atoi) that time_t and pid_t fit in int.
10863 Check for time_t and/or pid_t out of range, e.g., via a network share.
10864 Don't alloca where an auto var works fine.

10891 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10893 * lread.c (invalid_syntax): Omit length argument.
10894 All uses changed. This doesn't fix a bug, but it simplifies the
10895 code away from its former Hollerith-constant appearance, and it's
10896 one less 'int' to worry about when looking at integer-overflow issues.
10897 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10899 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10900 This didn't break anything, but it didn't help either.
10901 It's confusing to put a bogus integer in a place where the actual
10902 value does not matter.
10903 (LIST_END_P): Remove unused macro and its bogus comment.
10904 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10906 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10907 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10909 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10910 We prefer signed types, and the value cannot exceed the EMACS_INT
10911 range anyway (because otherwise the length would not be representable).
10912 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10913 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10914 This avoids a GCC warning when WIDE_EMACS_INT.
10916 * indent.c (sane_tab_width): New function.
10917 (current_column, scan_for_column, Findent_to, position_indentation)
10918 (compute_motion): Use it. This is just for clarity.
10919 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10921 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10923 * lisp.h (lint_assume): New macro.
10924 * composite.c (composition_gstring_put_cache):
10925 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10927 * editfns.c, insdel.c:
10928 Omit unnecessary forward decls, to simplify future changes.
10930 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10932 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10934 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10935 Use much-faster test for byte-length change.
10936 Don't assume string byte-length fits in 'int'.
10937 Check that character arg fits in 'int'.
10938 (mapcar1): Declare byte as byte, for clarity.
10940 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10942 * fns.c (concat): Catch string overflow earlier.
10943 Do not rely on integer wraparound.
10945 * dispextern.h (struct it.overlay_strings_charpos)
10946 (struct it.selective): Now EMACS_INT, not int.
10947 * xdisp.c (forward_to_next_line_start)
10948 (back_to_previous_visible_line_start)
10949 (reseat_at_next_visible_line_start, next_element_from_buffer):
10950 Don't arbitrarily truncate the value of 'selective' to int.
10952 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10954 * composite.c: Don't truncate sizes to 'int'.
10955 (composition_gstring_p, composition_reseat_it)
10956 (composition_adjust_point): Use EMACS_INT, not int.
10957 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10958 not EMACS_UINT, for indexes.
10960 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10962 * buffer.c: Include <verify.h>.
10963 (struct sortvec.priority, struct sortstr.priority):
10964 Now EMACS_INT, not int.
10965 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10966 (struct sortstr.size, record_overlay_string)
10967 (struct sortstrlist.size, struct sortlist.used):
10968 Don't truncate size to int.
10969 (record_overlay_string): Check for size-calculation overflow.
10970 (init_buffer_once): Check at compile-time, not run-time.
10972 2011-06-22 Jim Meyering <meyering@redhat.com>
10974 Don't leak an XBM-image-sized buffer
10975 * image.c (xbm_load): Free the image buffer after using it.
10977 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10980 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10981 that Sun C diagnosed.
10982 * fns.c (secure_hash): Fix pointer signedness issue.
10983 * intervals.c (static_offset_intervals): New function.
10984 (offset_intervals): Use it.
10986 2011-06-21 Leo Liu <sdl.web@gmail.com>
10989 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10992 * fns.c (secure_hash): Rename from crypto_hash_function and change
10993 the first arg to accept symbols.
10994 (Fsecure_hash): New primitive.
10995 (syms_of_fns): New symbols.
10997 2011-06-20 Deniz Dogan <deniz@dogan.se>
10999 * process.c (Fset_process_buffer): Clarify return value in
11002 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
11004 * dispnew.c (add_window_display_history): Use BVAR.
11006 * xdisp.c (debug_method_add): Use BVAR.
11007 (check_window_end, dump_glyph_matrix, dump_glyph)
11008 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
11010 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
11013 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
11014 check till after the cache is created in init_frame_faces.
11016 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
11018 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
11020 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
11022 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
11023 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
11024 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
11026 Improve buffer-overflow checking (Bug#8873).
11027 * fileio.c (Finsert_file_contents):
11028 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
11029 Remove the old (too-loose) buffer overflow checks.
11030 They weren't needed, since make_gap checks for buffer overflow.
11031 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
11032 The old code merely checked for Emacs fixnum overflow, and relied
11033 on undefined (wraparound) behavior. The new code avoids undefined
11034 behavior, and also checks for ptrdiff_t and/or size_t overflow.
11036 * editfns.c (Finsert_char): Don't dump core with very negative counts.
11037 Tune. Don't use wider integers than needed. Don't use alloca.
11038 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
11040 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
11042 * insdel.c, lisp.h (buffer_overflow): New function.
11043 (insert_from_buffer_1, replace_range, replace_range_2):
11044 * insdel.c (make_gap_larger):
11045 * editfns.c (Finsert_char):
11046 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
11048 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
11050 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
11052 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
11054 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
11055 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
11057 * fileio.c: Don't assume EMACS_INT fits in off_t.
11058 (emacs_lseek): New static function.
11059 (Finsert_file_contents, Fwrite_region): Use it.
11060 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
11062 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
11064 * fns.c: Don't overflow int when computing a list length.
11065 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
11066 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
11067 truncation on 64-bit hosts. Check for QUIT every
11068 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
11069 faster and is responsive enough.
11070 (Flength): Report an error instead of overflowing an integer.
11071 (Fsafe_length): Return a float if the value is not representable
11072 as a fixnum. This shouldn't happen except in contrived situations.
11073 (Fnthcdr, Fsort): Don't assume list length fits in int.
11074 (Fcopy_sequence): Don't assume vector length fits in int.
11076 * alloc.c: Check that resized vectors' lengths fit in fixnums.
11077 (header_size, word_size): New constants.
11078 (allocate_vectorlike): Don't check size overflow here.
11079 (allocate_vector): Check it here instead, since this is the only
11080 caller of allocate_vectorlike that could cause overflow.
11081 Check that the new vector's length is representable as a fixnum.
11083 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11084 The previous code was bogus. For example, next_almost_prime (32)
11085 returned 39, which is undesirable as it is a multiple of 3; and
11086 next_almost_prime (24) returned 25, which is a multiple of 5 so
11087 why was the code bothering to check for multiples of 7?
11089 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11091 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11093 Variadic C functions now count arguments with ptrdiff_t.
11094 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11095 Back then I didn't know that the Emacs coding style prefers signed int.
11096 Also, in the meantime I found a few more instances where arguments
11097 were being counted with int, which may truncate counts on 64-bit
11098 machines, or EMACS_INT, which may be unnecessarily wide.
11099 * lisp.h (struct Lisp_Subr.function.aMANY)
11100 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11101 Arg counts are now ptrdiff_t, not size_t.
11102 All variadic functions and their callers changed accordingly.
11103 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11104 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11105 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11106 * callint.c (Fcall_interactively): Check arg count for overflow,
11107 to avoid potential buffer overrun. Use signed char, not 'int',
11108 for 'varies' array, so that we needn't bother to check its size
11109 calculation for overflow.
11110 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11111 * eval.c (apply_lambda):
11112 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11113 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11114 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11116 * callint.c (Fcall_interactively): Don't use index var as event count.
11118 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11119 * mem-limits.h (SIZE): Remove; no longer used.
11121 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11123 Remove unnecessary casts.
11124 * xterm.c (x_term_init):
11125 * xfns.c (x_set_border_pixel):
11126 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11127 These aren't needed now that we assume ANSI C.
11129 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11130 It's more likely to cause problems (due to unsigned overflow)
11133 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11135 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11137 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11139 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11141 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11143 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11145 GLYPH_CODE_FACE returns EMACS_INT, not int.
11146 * dispextern.h (merge_faces):
11147 * xfaces.c (merge_faces):
11148 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11149 Don't assume EMACS_INT fits in int.
11151 * character.h (CHAR_VALID_P): Remove unused parameter.
11152 * fontset.c, lisp.h, xdisp.c: All uses changed.
11154 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11156 * fns.c (concat): Minor tuning based on overflow analysis.
11157 This doesn't fix any bugs. Use int to hold character, instead
11158 of constantly refetching from Emacs object. Use XFASTINT, not
11159 XINT, for value known to be a character. Don't bother comparing
11160 a single byte to 0400, as it's always less.
11162 * floatfns.c (Fexpt):
11163 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11165 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11168 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11170 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11171 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11172 incorrectly succeed when S was a string, because 4294967386 was
11173 truncated before it was used.
11175 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11176 Otherwise, an out-of-range integer could cause undefined behavior
11179 * composite.c: Use int, not EMACS_INT, for characters.
11180 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11181 EMACS_INT, for values that are known to be in character range.
11182 This doesn't fix any bugs but is the usual style inside Emacs and
11183 may generate better code on 32-bit machines.
11185 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11186 This is for reasons similar to the recent CHAR_STRING fix.
11187 * charset.c (Fencode_char): Check that character arg is actually
11188 a character. Pass an int to ENCODE_CHAR.
11189 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11190 wider than 'int', as a compile-time check to prevent future regressions
11193 * character.c (char_string): Remove unnecessary casts.
11195 Make sure a 64-bit char is never passed to CHAR_STRING.
11196 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11197 by silently ignoring the top 32 bits, allowing some values
11198 that were far too large to be valid characters.
11199 * character.h: Include <verify.h>.
11200 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11201 arguments are no wider than unsigned, as a compile-time check
11202 to prevent future regressions in this area.
11204 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11205 (Fsubst_char_in_region):
11207 * xdisp.c (decode_mode_spec_coding):
11208 Adjust to CHAR_STRING's new requirement.
11209 * editfns.c (Finsert_char, Fsubst_char_in_region):
11210 * fns.c (concat): Check that character args are actually
11211 characters. Without this test, these functions did the wrong
11212 thing with wildly out-of-range values on 64-bit hosts.
11214 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11215 These casts should not be needed on 32-bit hosts, either.
11216 * keyboard.c (read_char):
11217 * lread.c (Fload): Remove casts to unsigned.
11219 * lisp.h (UNSIGNED_CMP): New macro.
11220 This fixes comparison bugs on 64-bit hosts.
11221 (ASCII_CHAR_P): Use it.
11222 * casefiddle.c (casify_object):
11223 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11224 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11225 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11226 * dispextern.h (FACE_FROM_ID):
11227 * keyboard.c (read_char): Use UNSIGNED_CMP.
11229 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11230 not to EMACS_INT, to avoid GCC warning.
11232 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11234 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11235 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11236 isn't needed on 32-bit machines.
11238 * buffer.c (Fgenerate_new_buffer_name):
11239 Use EMACS_INT for count, not int.
11240 (advance_to_char_boundary): Return EMACS_INT, not int.
11242 * data.c (Qcompiled_function): Now static.
11244 * window.c (window_body_lines): Now static.
11246 * image.c (gif_load): Rename local to avoid shadowing.
11248 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11249 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11250 * alloc.c (make_save_value): Integer argument is now of type
11251 ptrdiff_t, not int.
11252 (mark_object): Use ptrdiff_t, not int.
11253 * lisp.h (pD): New macro.
11254 * print.c (print_object): Use it.
11256 * alloc.c: Use EMACS_INT, not int, to count objects.
11257 (total_conses, total_markers, total_symbols, total_vector_size)
11258 (total_free_conses, total_free_markers, total_free_symbols)
11259 (total_free_floats, total_floats, total_free_intervals)
11260 (total_intervals, total_strings, total_free_strings):
11261 Now EMACS_INT, not int. All uses changed.
11262 (Fgarbage_collect): Compute overall total using a double, so that
11263 integer overflow is less likely to be a problem. Check for overflow
11264 when converting back to an integer.
11265 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11266 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11267 These were 'int' variables that could overflow on 64-bit hosts;
11268 they were never used, so remove them instead of repairing them.
11269 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11270 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
11271 Previously, this ceilinged at INT_MAX, but that doesn't work on
11273 (allocate_pseudovector): Don't use EMACS_INT when int would do.
11275 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
11276 (allocate_vectorlike): Check for ptrdiff_t overflow.
11277 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
11278 when a (possibly-narrower) signed value would do just as well.
11279 We prefer using signed arithmetic, to avoid comparison confusion.
11281 * alloc.c: Catch some string size overflows that we were missing.
11282 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
11283 for convenience in STRING_BYTES_MAX.
11284 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11285 The definition here is exact; the one in lisp.h was approximate.
11286 (allocate_string_data): Check for string overflow. This catches
11287 some instances we weren't catching before. Also, it catches
11288 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11289 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11290 and ptrdiff_t and EMACS_INT are both 64 bits.
11292 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11293 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
11294 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
11296 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
11298 * alloc.c (Fmake_string): Check for out-of-range init.
11300 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
11302 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
11304 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
11306 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
11307 xg_get_default_scrollbar_width.
11309 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
11310 (int_gtk_range_get_value): Move to the scroll bar part of the file.
11311 (style_changed_cb): Call update_theme_scrollbar_width and call
11312 x_set_scroll_bar_default_width and xg_frame_set_char_size for
11313 all frames (Bug#8505).
11314 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
11315 Call gtk_window_set_resizable if HAVE_GTK3.
11316 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
11317 and height if HAVE_GTK3 (Bug#8505).
11318 (scroll_bar_width_for_theme): New variable.
11319 (update_theme_scrollbar_width): New function.
11320 (xg_get_default_scrollbar_width): Move code to
11321 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
11322 (xg_initialize): Call update_theme_scrollbar_width.
11324 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
11326 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
11328 2011-06-12 Martin Rudalics <rudalics@gmx.at>

11790 (Fwindow_minibuffer_p): Move up in code and simplify.
11791 (Fset_frame_selected_window): Move here from frame.c.
11793 (Fselected_window, select_window, Fselect_window): Move up in
11794 code. Minor doc-string fixes.
11796 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
11798 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
11799 Do not assume that spare memory exists; that assumption is valid
11800 only if SYSTEM_MALLOC.
11801 (LARGE_REQUEST): New macro, so that the issue of large requests
11802 is separated from the issue of spare memory.
11804 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
11806 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

11832 New error handlers.
11833 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
11834 Obey Vx_select_enable_clipboard_manager. Catch errors in
11835 x_clipboard_manager_save (Bug#8779).
11836 (Vx_select_enable_clipboard_manager): New variable.
11837 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
11839 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
11841 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
11843 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11845 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
11846 in the current matrix if keep_current_p is non-zero.

11850 * bidi.c (bidi_level_of_next_char): Fix last change.
11852 2011-06-03 Eli Zaretskii <eliz@gnu.org>
11854 Support bidi reordering of text covered by display properties.
11856 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
11857 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
11858 (bidi_cache_search, bidi_cache_iterator_state)
11859 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11860 (bidi_level_of_next_char, bidi_move_to_visually_next):
11861 Support character positions inside a run of characters covered by a
11863 (bidi_paragraph_init, bidi_resolve_explicit_1)
11864 (bidi_level_of_next_char): Call bidi_fetch_char and
11865 bidi_fetch_char_advance instead of FETCH_CHAR and
11866 FETCH_CHAR_ADVANCE.

11868 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11870 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11871 instead of using explicit *_CHAR codes.
11872 (bidi_resolve_explicit, bidi_resolve_weak):
11873 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11874 bidirectional text is supported only in multibyte buffers.
11875 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11876 it to initialize the frame_window_p member of struct bidi_it.
11877 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11878 (bidi_resolve_explicit, bidi_resolve_weak)

11880 bidi_it->nchars is non-positive.
11881 (bidi_level_of_next_char): Don't try to lookup the cache for the
11882 next/previous character if nothing is cached there yet, or if we
11883 were just reseat()'ed to a new position.
11885 * xdisp.c (set_cursor_from_row): Set start and stop points
11886 according to the row's direction when priming the loop that looks
11887 for the glyph on which to display cursor.
11888 (single_display_spec_intangible_p): Function deleted.
11889 (display_prop_intangible_p): Reimplement to call
11890 handle_display_spec instead of single_display_spec_intangible_p.
11891 Accept 3 additional arguments needed by handle_display_spec.
11892 This fixes incorrect cursor motion across display property with complex
11893 values: lists, `(when COND...)' forms, etc.
11894 (single_display_spec_string_p): Support property values that are
11895 lists with the argument STRING its top-level element.
11896 (display_prop_string_p): Fix the condition for processing a
11897 property that is a list to be consistent with handle_display_spec.
11898 (handle_display_spec): New function, refactored from the
11899 last portion of handle_display_prop.
11900 (compute_display_string_pos): Accept additional argument
11901 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11902 value of a `display' property is a "replacing spec".
11903 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11904 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11905 the display property, but just return a value indicating whether
11906 the display property will replace the characters it covers.
11907 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11908 frame_window_p members of struct bidi_it.
11909 (compute_display_string_pos, compute_display_string_end):
11911 (push_it): Accept second argument POSITION, where pop_it should
11912 jump to continue iteration.
11913 (reseat_1): Initialize bidi_it.disp_pos.
11915 * keyboard.c (adjust_point_for_property): Adjust the call to
11916 display_prop_intangible_p to its new signature.
11918 * dispextern.h (struct bidi_it): New member frame_window_p.
11919 (bidi_init_it): Update prototypes.
11920 (display_prop_intangible_p): Update prototype.
11921 (compute_display_string_pos, compute_display_string_end):
11922 Declare prototypes.
11923 (struct bidi_it): New members nchars and disp_pos. ch_len is now
11926 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
11928 Malloc failure behavior now depends on size of allocation.
11929 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11930 * lisp.h: Change signatures accordingly.
11931 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11932 All callers changed. (Bug#8762)
11934 * gnutls.c: Use Emacs's memory allocators.
11935 Without this change, the gnutls library would invoke malloc etc.
11936 directly, which causes problems on non-SYNC_INPUT hosts, and which
11937 runs afoul of improving memory_full behavior. (Bug#8761)
11938 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11939 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11940 xfree instead of the default malloc, realloc, free.
11941 (Fgnutls_boot): No need to check for memory allocation failure,
11942 since xmalloc does that for us.
11944 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11945 * category.c (hash_get_category_set):
11946 * ccl.c (ccl_driver):
11947 * charset.c (Fdefine_charset_internal):
11948 * charset.h (struct charset.hash_index):
11949 * composite.c (get_composition_id, gstring_lookup_cache)
11950 (composition_gstring_put_cache):
11951 * composite.h (struct composition.hash_index):
11952 * dispextern.h (struct image.hash):
11953 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
11954 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
11955 (hashfn_equal, hashfn_user_defined, make_hash_table)
11956 (maybe_resize_hash_table, hash_lookup, hash_put)
11957 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
11958 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
11959 (Fsxhash, Fgethash, Fputhash, Fmaphash):
11960 * image.c (make_image, search_image_cache, lookup_image)
11961 (xpm_put_color_table_h):
11962 * lisp.h (struct Lisp_Hash_Table):
11963 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11964 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11965 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11966 * alloc.c (allocate_vectorlike):
11967 Check for overflow in vector size calculations.
11968 * ccl.c (ccl_driver):
11969 Check for overflow when converting EMACS_INT to int.
11970 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11971 need to be updated by these changes.
11972 * fns.c (make_hash_table, maybe_resize_hash_table):
11973 Check for integer overflow with large hash tables.
11974 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11975 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11976 (SXHASH_REDUCE): New macro.
11977 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11978 Use it instead of discarding useful hash info with large hash values.
11979 (sxhash_float): New function.
11980 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11981 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11982 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11983 Rewrite to use FIXNUM_BITS, as this simplifies things.
11984 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11985 Adjust signatures to match updated version of code.
11986 (consing_since_gc): Now EMACS_INT, since a single hash table can
11987 use more than INT_MAX bytes.
11989 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11991 Make it possible to build with GCC-4.6+ -O2 -flto.
11993 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11995 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11997 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11998 Call minibuffer-inactive-mode.
12000 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
12002 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
12003 Update dependencies.
12005 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12007 * data.c (init_data): Remove code for UTS, this system is not
12010 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12012 Don't force ./temacs to start in terminal mode.
12014 * frame.c (make_initial_frame): Initialize faces in all cases, not
12015 only when CANNOT_DUMP is defined.
12016 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
12018 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12020 * dispnew.c (add_window_display_history): Use const for the string
12021 pointer. Remove declaration, not needed.
12023 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12025 Use 'inline', not 'INLINE'.
12026 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
12027 * alloc.c, fontset.c (INLINE): Remove.
12028 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
12029 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
12030 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
12031 * gmalloc.c (register_heapinfo): Use inline unconditionally.
12032 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
12034 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12036 Make it possible to run ./temacs.
12038 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
12039 syms_of_callproc does the same thing. Remove test for
12040 "initialized", do it in the caller.
12041 * emacs.c (main): Avoid calling set_initial_environment when dumping.
12043 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
12045 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
12046 (read_minibuf): Use get_minibuffer.
12047 (syms_of_minibuf): Use DEFSYM.
12048 (Qmetadata): New var.
12049 * data.c (Qbuffer): Don't make it static.
12050 (syms_of_data): Use DEFSYM.
12052 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12054 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
12055 (CCL_CODE_MIN): New macro.
12057 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
12059 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
12061 * eval.c (Qdebug): Now static.
12062 * lisp.h (Qdebug): Remove decl. This reverts a part of the
12063 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
12064 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
12066 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12068 * image.c: Various fixes to ImageMagick code comments.
12069 (Fimagemagick_types): Doc fix.
12071 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
12073 Minor fixes prompted by GCC 4.6.0 warnings.
12075 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12077 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12078 (x_clipboard_manager_save_all): Move extern decl to ...
12079 * xterm.h: ... here, so that it can be checked for consistency.
12081 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12083 * xselect.c (x_clipboard_manager_save_frame)
12084 (x_clipboard_manager_save_all): New functions.
12085 (Fx_clipboard_manager_save): Lisp function deleted.
12087 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12088 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12090 * xterm.h: Update prototype.
12092 2011-05-28 William Xu <william.xwl@gmail.com>
12094 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12095 exiting (Bug#8239).
12097 2011-05-28 Jim Meyering <meyering@redhat.com>
12099 Avoid a sign-extension bug in crypto_hash_function.
12100 * fns.c (to_uchar): Define.
12101 (crypto_hash_function): Use it to convert some newly-signed
12102 variables to unsigned, to avoid sign-extension bugs. For example,
12103 without this change, (md5 "truc") would evaluate to
12104 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12105 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12106 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12108 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12110 Integer overflow fixes.
12112 * dbusbind.c: Serial number integer overflow fixes.
12113 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12114 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12115 to hold a serial number that is too large for a fixnum.
12116 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12117 Check for serial numbers out of range. Decode any serial number
12118 that was so large that it became a float. (Bug#8722)
12120 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12121 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12122 Use XFASTINT rather than XUINT when numbers are nonnegative.
12123 (xd_append_arg, Fdbus_method_return_internal):
12124 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12125 arguments, check that Lisp number is nonnegative, rather than
12126 silently wrapping negative numbers around. (Bug#8722)
12127 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12130 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12132 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12134 ccl: Add integer overflow checks.
12135 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12136 (IN_INT_RANGE): New macros.
12137 (ccl_driver): Use them to check for integer overflow when
12138 decoding a CCL program. Many of the new checks are whether XINT (x)
12139 fits in int; it doesn't always, on 64-bit hosts. The new version
12140 doesn't catch all possible integer overflows, but it's an
12141 improvement. (Bug#8719)
12143 * alloc.c (make_event_array): Use XINT, not XUINT.
12144 There's no need for unsigned here.
12146 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12147 This follows up to the 2011-05-06 change that substituted uintptr_t
12148 for EMACS_INT. This case wasn't caught back then.
12150 Rework Fformat to avoid integer overflow issues.
12151 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12152 now (part of C89). Include <verify.h>.
12153 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12154 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12155 (Fformat): Avoid the prepass trying to compute sizes; it was only
12156 approximate and thus did not catch overflow reliably. Instead, walk
12157 through the format just once, formatting and computing sizes as we go,
12158 checking for integer overflow at every step, and allocating a larger
12159 buffer as needed. Keep track separately whether the format is
12160 multibyte. Keep only the most-recently calculated precision, rather
12161 than them all. Record whether each argument has been converted to
12162 string. Use EMACS_INT, not int, for byte and char and arg counts.
12163 Support field widths and precisions larger than INT_MAX. Avoid
12164 sprintf's undefined behavior with conversion specifications such as %#d
12165 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12166 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12167 formatting out-of-range floating point numbers with int
12168 formats. (Bug#8668)
12170 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12172 * data.c: Avoid integer truncation in expressions involving floats.
12173 * data.c: Include <intprops.h>.
12174 (arith_driver): When there's an integer overflow in an expression
12175 involving floating point, convert the integers to floating point
12176 so that the resulting value does not suffer from catastrophic
12177 integer truncation. For example, on a 64-bit host (* 4
12178 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12179 Do not rely on undefined behavior after integer overflow.
12181 merge count_size_as_multibyte, parse_str_to_multibyte
12182 * character.c, character.h (count_size_as_multibyte):
12183 Rename from parse_str_to_multibyte; all uses changed.
12184 Check for integer overflow.
12185 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12186 since it's now a duplicate of the other. This is more of
12187 a character than a buffer op, so better that it's in character.c.
12188 * fns.c, print.c: Adjust to above changes.
12190 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12192 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12194 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12196 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12197 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12198 (x_clipboard_manager_save): Now static.
12199 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12201 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12202 (crypto_hash_function): Now static.
12203 Fix pointer signedness problems. Avoid unnecessary initializations.
12205 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12207 * termhooks.h (Vselection_alist): Make it terminal-local.
12209 * terminal.c (create_terminal): Initialize it.
12211 * xselect.c: Support for clipboard managers.
12212 (Vselection_alist): Move to termhooks.h as terminal-local var.
12213 (LOCAL_SELECTION): New macro.
12214 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12215 (symbol_to_x_atom): Remove gratuitous arg.
12216 (x_handle_selection_request, lisp_data_to_selection_data)
12217 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12218 (x_own_selection, x_get_local_selection, x_convert_selection):
12219 New arg, specifying work frame. Use terminal-local Vselection_alist.
12220 (some_frame_on_display): Delete unused function.
12221 (Fx_own_selection_internal, Fx_get_selection_internal)
12222 (Fx_disown_selection_internal, Fx_selection_owner_p)
12223 (Fx_selection_exists_p): New optional frame arg.
12224 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12225 (x_handle_selection_clear): Don't treat other terminals with the
12226 same keyboard specially. Use the terminal-local Vselection_alist.
12227 (x_clear_frame_selections): Use Frun_hook_with_args.
12229 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12231 * xterm.h: Add support for those atoms.
12233 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12235 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12236 (converted_selections, conversion_fail_tag): New global variables.
12237 (x_selection_request_lisp_error): Free the above.
12238 (x_get_local_selection): Remove unnecessary code.
12239 (x_reply_selection_request): Args changed; handle arbitrary array
12240 of converted selections stored in converted_selections.
12241 Separate the XChangeProperty and SelectionNotify steps.
12242 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12243 (x_convert_selection): New function.
12244 (x_handle_selection_event): Simplify.
12245 (x_get_foreign_selection): Don't ignore incoming requests while
12246 waiting for an answer; this will fail when we implement
12247 SAVE_TARGETS, and seems unnecessary anyway.
12248 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12249 (Vx_sent_selection_functions): Doc fix.
12251 2011-05-26 Leo Liu <sdl.web@gmail.com>
12253 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12255 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12257 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12259 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12260 for fringe update if it has periodic bitmap.
12261 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12262 and fringe_bitmap_periodic_p.
12264 * fringe.c (get_fringe_bitmap_data): New function.
12265 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12266 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12267 row. Mark glyph row for fringe update if periodicity changed.
12269 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12270 for fringe update unless it has periodic bitmap.
12272 2011-05-25 Kenichi Handa <handa@m17n.org>
12274 * xdisp.c (get_next_display_element): Set correct it->face_id for
12275 a static composition.
12277 2011-05-24 Leo Liu <sdl.web@gmail.com>
12280 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12282 * fns.c (crypto_hash_function, Fsha1): New function.
12283 (Fmd5): Use crypto_hash_function.
12284 (syms_of_fns): Add Ssha1.
12286 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12288 * gnutls.c: Remove unused macros.
12289 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12290 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12291 Remove macros that are defined and never used.
12292 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12294 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12296 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12297 (Fx_get_selection_internal): Minor cleanup.
12298 (Fx_own_selection_internal): Rename arguments for consistency with
12301 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12303 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12305 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12307 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12309 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12311 * dispnew.c (scrolling_window): Don't exclude the case that the
12312 last enabled row in the desired matrix touches the bottom boundary.
12314 2011-05-21 Glenn Morris <rgm@gnu.org>
12316 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12317 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12318 and add some more files.
12320 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12322 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12323 report_file_error introduced by the change from 2011-05-07.
12325 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12327 * systime.h (Time): Define only if emacs is defined.
12328 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12329 where the include path doesn't have X11/X.h by default. See
12330 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12332 2011-05-20 Kenichi Handa <handa@m17n.org>
12334 * composite.c (find_automatic_composition): Fix previous change.
12336 2011-05-20 Glenn Morris <rgm@gnu.org>
12338 * lisp.mk: New file, split from Makefile.in.
12339 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12340 (shortlisp): Remove.
12341 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12343 2011-05-19 Glenn Morris <rgm@gnu.org>
12345 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12346 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12347 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12348 (lisp): Set the order to that of loadup.el.
12349 (shortlisp): Make it a copy of $lisp.
12350 (SOME_MACHINE_LISP): Remove.
12351 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12352 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12354 2011-05-18 Kenichi Handa <handa@m17n.org>
12356 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12357 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12358 (find_automatic_composition): Mostly rewrite for efficiency.
12360 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12362 * makefile.w32-in: Update dependencies.
12364 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12366 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12367 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12369 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12371 Fix some integer overflow issues, such as string length overflow.
12373 * insdel.c (count_size_as_multibyte): Check for string overflow.
12375 * character.c (lisp_string_width): Check for string overflow.
12376 Use EMACS_INT, not int, for string indexes and lengths; in
12377 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12378 the resulting string length overflows an EMACS_INT; instead,
12379 report a string overflow if no precision given. When checking for
12380 precision exhaustion, use a check that cannot possibly have
12381 integer overflow. (Bug#8675)
12382 * character.h (lisp_string_width): Adjust to new signature.
12384 * alloc.c (string_overflow): New function.
12385 (Fmake_string): Use it. This doesn't change behavior, but saves
12386 a few bytes and will simplify future changes.
12387 * character.c (string_escape_byte8): Likewise.
12388 * lisp.h (string_overflow): New decl.
12390 Fixups, following up to the user-interface timestamp change.
12391 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12392 for UI timestamps, instead of unsigned long.
12393 * msdos.c (mouse_get_pos): Likewise.
12394 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12395 * w32gui.h (Time): Define by including "systime.h" rather than by
12396 declaring it ourselves. (Bug#8664)
12398 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12399 * image.c (clear_image_cache): Likewise.
12401 * term.c (term_mouse_position): Don't assume time_t wraparound.
12403 Be more systematic about user-interface timestamps.
12404 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12405 and sometimes 'EMACS_UINT', to represent these timestamps.
12406 This change causes it to use 'Time' uniformly, as that's what X uses.
12407 This makes the code easier to follow, and makes it easier to catch
12408 integer overflow bugs such as Bug#8664.
12409 * frame.c (Fmouse_position, Fmouse_pixel_position):
12410 Use Time, not unsigned long, for user-interface timestamps.
12411 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12412 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12413 * keyboard.h (last_event_timestamp): Likewise.
12414 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12415 * menu.h (xmenu_show): Likewise.
12416 * term.c (term_mouse_position): Likewise.
12417 * termhooks.h (struct input_event.timestamp): Likewise.
12418 (struct terminal.mouse_position_hook): Likewise.
12419 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12420 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12421 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12422 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12423 what it was before.
12424 * menu.h, termhooks.h: Include "systime.h", for Time.
12426 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12427 Don't assume that the difference between two unsigned long values
12428 can fit into an integer. At this point, we know button_down_time
12429 <= event->timestamp, so the difference must be nonnegative, so
12430 there's no need to cast the result if double-click-time is
12431 nonnegative, as it should be; check that it's nonnegative, just in
12432 case. This bug is triggered when events are more than 2**31 ms
12433 apart (about 25 days). (Bug#8664)
12435 * xselect.c (last_event_timestamp): Remove duplicate decl.
12436 (x_own_selection): Remove needless cast to unsigned long.
12438 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12439 that always fit in int. Use a sentinel instead of a counter, to
12440 avoid a temp and to allay GCC's concerns about possible int overflow.
12441 * frame.h (struct frame): Use int for menu_bar_items_used
12442 instead of EMACS_INT, since it always fits in int.
12444 * menu.c (grow_menu_items): Check for int overflow.
12446 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12448 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12449 Before, the code was not consistent. These values cannot exceed
12450 2**31 - 1 so there's no need to make them unsigned.
12451 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12452 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12453 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12455 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12457 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12458 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12459 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12460 presumably because the widths might not match.
12462 * window.c (size_window): Avoid needless test at loop start.
12464 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12466 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12468 2011-05-12 Drew Adams <drew.adams@oracle.com>
12470 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12472 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12474 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12475 `width' to `bar_area_x' and `bar_area_width', respectively.
12476 (x_scroll_run): Take account of fringe background extension.
12478 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12479 Rename local vars `left' and `width' to `bar_area_x' and
12480 `bar_area_width', respectively.
12481 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12482 background extension.
12484 2011-05-10 Jim Meyering <meyering@redhat.com>
12486 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12488 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12490 * image.c (Finit_image_library): Return t for built-in image types,
12491 like pbm and xbm. (Bug#8640)
12493 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12495 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12497 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12499 * w32console.c (Fset_screen_color): Doc fix.
12500 (Fget_screen_color): New function.
12501 (syms_of_ntterm): Defsubr it.
12503 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12504 unlink the temporary file if Fcall_process didn't create it in the
12506 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12507 child process will be redirected to a file specified with `:file'.
12508 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12509 cue to call_process_cleanup not to close that handle.
12511 2011-05-07 Ben Key <bkey76@gmail.com>
12513 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12514 one of two shell specific rules, either bootstrap-temacs-CMD or
12515 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12516 to the previous implementation of the bootstrap-temacs rule.
12517 The bootstrap-temacs-CMD rule is similar to the previous
12518 implementation of the bootstrap-temacs rule except that it
12519 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12522 These changes, along with some changes to nt/configure.bat,
12523 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12524 earlier fix to add support for --cflags and --ldflags options
12525 that include quotes so that it works whether make uses cmd or
12528 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12530 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12531 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12533 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12534 a string. Handle both cases.
12535 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12536 (Fdbus_register_method): Use Qinvalid_function.
12538 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12540 * makefile.w32-in: Update dependencies.
12541 (LISP_H): Add inttypes.h and stdin.h.
12542 (PROCESS_H): Add unistd.h.
12544 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12546 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12547 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12549 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12551 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12553 * term.c (vfatal): Remove stray call to va_end.
12554 It's not needed and the C Standard doesn't allow it here anyway.
12556 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12557 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12559 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12562 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12564 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12566 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12568 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12570 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12572 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12573 * charset.c (Fdefine_charset_internal): Don't initialize
12574 charset.code_space[15]. The value was garbage, on hosts with
12575 32-bit int (Bug#8600).
12577 * lread.c (read_integer): Be more consistent with string-to-number.
12578 Use string_to_number to do the actual conversion; this avoids
12579 rounding errors and fixes some other screwups. Without this fix,
12580 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12581 (digit_to_number): Move earlier, for benefit of read_integer.
12582 Return -1 if the digit is out of range for the base, -2 if it is
12583 not a digit in any supported base. (Bug#8602)
12585 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12587 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12588 to match comment at start of function. This also removes a
12589 GCC warning about overflow in a 32+64-bit port.
12591 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12593 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12594 Reported by Stefan Monnier in
12595 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12596 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12597 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12599 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12600 (EMACS_UINTPTR): Likewise, with uintptr_t.
12602 * lisp.h: Prefer 64-bit EMACS_INT if available.
12603 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12604 on 32-bit hosts that have 64-bit int, so that they can access
12606 However, temporarily disable this change unless the temporary
12607 symbol WIDE_EMACS_INT is defined.
12609 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12611 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12612 This removes an assumption that EMACS_INT and long are the same
12613 width as pointers. The assumption is true for Emacs porting targets
12614 now, but we want to make other targets possible.
12615 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12616 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12617 In the rest of the code, change types of integers that hold casted
12618 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12619 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12620 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12621 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12622 No need to cast type when ORing.
12623 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12624 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12625 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12626 assume EMACS_INT is the same width as char *.
12627 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12628 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12629 Remove no-longer-needed casts.
12630 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12631 (xg_tool_bar_help_callback, xg_make_tool_item):
12632 Use EMACS_INTPTR to hold an integer
12633 that will be cast to void *; this can avoid a GCC warning
12634 if EMACS_INT is not the same width as void *.
12635 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12636 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12637 (current_message_1, set_message_1):
12638 Use a local to convert to proper width without a cast.
12639 * xmenu.c (dialog_selection_callback): Likewise.
12641 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12642 Also, don't assume VALBITS / RAND_BITS is less than 5,
12643 and don't rely on undefined behavior when shifting a 1 left into
12645 * lisp.h (get_random): Change signature to match.
12647 * lread.c (hash_string): Use size_t, not int, for hash computation.
12648 Normally we prefer signed values; but hashing is special, because
12649 it's better to use unsigned division on hash table sizes so that
12650 the remainder is nonnegative. Also, size_t is the natural width
12651 for hashing into memory. The previous code used 'int', which doesn't
12652 retain enough info to hash well into very large tables.
12653 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12655 * dbusbind.c: Don't possibly lose pointer info when converting.
12656 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12657 Use XPNTR rather than XHASH, so that the high-order bits of
12658 the pointer aren't lost when converting through void *.
12660 * eval.c (Fautoload): Don't double-shift a pointer.
12662 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

12696 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12697 Remove unused parameter `fildes'.
12698 * process.c (read_process_output, send_process): Don't pass it.
12700 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12702 Fix previous change: the library cache is defined in w32.c.
12703 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12704 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

12747 instead of gnutls_record_check_pending.
12749 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12751 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12753 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12754 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12757 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12759 * xterm.c (x_set_frame_alpha): Do not set property on anything

12794 (Fcall_process_region): Ditto.
12796 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12798 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12799 rather than `XVECTOR (FOO)->size'.
12801 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12802 inttypes.h, as a gnulib replacement is used if it not available in
12805 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12807 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12808 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12809 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12811 * coding.c (coding_alloc_by_realloc): Error out if destination
12812 will grow beyond MOST_POSITIVE_FIXNUM.
12813 (decode_coding_emacs_mule): Abort if there isn't enough place in
12814 charbuf for the composition carryover bytes. Reserve an extra

12869 Improve `doprnt' and its usage. (Bug#8545)
12870 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12871 `format_end'. Remove support for %l as a conversion specifier.
12872 Don't use xrealloc. Improve diagnostics when the %l size modifier
12873 is used. Update the commentary.
12875 * eval.c (verror): Simplify calculation of size_t.
12877 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12880 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12882 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12885 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12887 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12888 This makes this file independent of the recent pseudovector change.
12890 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12892 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12894 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12895 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12896 Remove unused local.
12897 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12899 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12900 GCC 4.6.0 optimizes based on type-based alias analysis.
12901 For example, if b is of type struct buffer * and v of type struct
12902 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12903 != &v->size, and therefore "v->size = 1; b->size = 2; return
12904 v->size;" must therefore return 1. This assumption is incorrect
12905 for Emacs, since it type-puns struct Lisp_Vector * with many other
12906 types. To fix this problem, this patch adds a new type struct
12907 vectorlike_header that documents the constraints on layout of vectors
12908 and pseudovectors, and helps optimizing compilers not get fooled
12909 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12910 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12911 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12913 (XSETPVECTYPE): Rewrite in terms of new macro.
12914 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12915 This is a bit clearer, and further avoids the possibility of
12916 undesirable aliasing.
12917 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12918 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12919 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12920 since Lisp_Subr is a special case (no "next" field).
12921 (ASIZE): Now uses header.size rather than size.
12922 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12923 to avoid the hassle of writing XVECTOR (foo)->header.size.
12924 (struct vectorlike_header): New type.
12925 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12926 object, to help avoid aliasing.
12927 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12928 (SUBRP): Likewise, since Lisp_Subr is a special case.
12929 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12930 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12931 (struct Lisp_Hash_Table): Combine first two members into a single
12932 struct vectorlike_header member. All uses of "size" and "next" members
12933 changed to be "header.size" and "header.next".
12934 * buffer.h (struct buffer): Likewise.
12935 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12936 * frame.h (struct frame): Likewise.
12937 * process.h (struct Lisp_Process): Likewise.
12938 * termhooks.h (struct terminal): Likewise.
12939 * window.c (struct save_window_data, struct saved_window): Likewise.
12940 * window.h (struct window): Likewise.
12941 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12942 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12943 * buffer.c (init_buffer_once): Likewise.
12944 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12946 * process.c (Fformat_network_address): Use local var for size,
12949 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12951 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12952 * data.c (atof): Remove decl; no longer used or needed.
12953 (digit_to_number): Move to lread.c.
12954 (Fstring_to_number): Use new string_to_number function, to be
12955 consistent with how the Lisp reader treats infinities and NaNs.
12956 Do not assume that floating-point numbers represent EMACS_INT
12957 without losing information; this is not true on most 64-bit hosts.
12958 Avoid double-rounding errors, by insisting on integers when
12959 parsing non-base-10 numbers, as the documentation specifies.
12960 * lisp.h (string_to_number): New decl, replacing ...
12961 (isfloat_string): Remove.
12962 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12963 (read1): Do not accept +. and -. as integers; this
12964 appears to have been a coding error. Similarly, do not accept
12965 strings like +-1e0 as floating point numbers. Do not report
12966 overflow for integer overflows unless the base is not 10 which
12967 means we have no simple and reliable way to continue.
12968 Break out the floating-point parsing into a new
12969 function string_to_number, so that Fstring_to_number parses
12970 floating point numbers consistently with the Lisp reader.
12971 (digit_to_number): Move here from data.c. Make it static inline.
12972 (E_CHAR, EXP_INT): Remove, replacing with ...
12973 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12974 (string_to_number): New function, replacing isfloat_string.
12975 This function checks for valid syntax and produces the resulting
12976 Lisp float number too. Rework it so that string-to-number
12977 no longer mishandles examples like "1.0e+". Use strtoumax,
12978 so that overflow for non-base-10 numbers is reported only when
12979 there's no portable and simple way to convert to floating point.
12981 * textprop.c (set_text_properties_1): Rewrite for clarity,
12982 and to avoid GCC warning about integer overflow.
12984 * intervals.h (struct interval): Use EMACS_INT for members
12985 where EMACS_UINT might cause problems. See
12986 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12987 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12988 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12990 (offset_intervals): Tell GCC not to worry about length overflow
12991 when negating a negative length.
12993 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12994 (overrun_check_free): Likewise.
12996 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12997 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
13000 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13001 (gnutls_make_error): Rename local to avoid shadowing.
13002 (gnutls_emacs_global_deinit): ifdef out; not used.
13003 (Fgnutls_boot): Use const for pointer to readonly storage.
13004 Comment out unused local. Fix pointer signedness problems.
13006 * lread.c (openp): Don't stuff size_t into an 'int'.
13007 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
13008 about possible signed overflow.
13010 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13011 (GDK_KEY_g): Don't define if already defined.
13012 (xg_prepare_tooltip): Avoid pointer signedness problem.
13013 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
13015 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
13016 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
13018 * xfns.c (Fx_window_property): Simplify a bit,
13019 to make a bit faster and to avoid GCC 4.6.0 warning.
13020 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
13022 * fns.c (internal_equal): Don't assume size_t fits in int.
13024 * alloc.c (compact_small_strings): Tighten assertion a little.
13026 Replace pEd with more-general pI, and fix some printf arg casts.
13027 * lisp.h (pI): New macro, generalizing old pEd macro to other
13028 conversion specifiers. For example, use "...%"pI"d..." rather
13029 than "...%"pEd"...".
13030 (pEd): Remove. All uses replaced with similar uses of pI.
13031 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
13032 * alloc.c (check_pure_size): Don't overflow by converting size to int.
13033 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
13034 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
13035 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
13036 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
13037 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
13039 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
13040 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
13041 * print.c (safe_debug_print, print_object): Likewise.
13042 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
13044 Use pI instead of if-then-else-abort. Use %p to avoid casts,
13045 avoiding the 0 flag, which is not portable.
13046 * process.c (Fmake_network_process): Use pI to avoid cast.
13047 * region-cache.c (pp_cache): Likewise.
13048 * xdisp.c (decode_mode_spec): Likewise.
13049 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
13050 behavior on 64-bit hosts with printf arg.
13051 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
13052 (x_stop_queuing_selection_requests): Likewise.
13053 (x_get_window_property): Don't truncate byte count to an 'int'
13056 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
13057 here, since it parses constructs like leading '-' and spaces,
13058 which are not wanted; and it overflows with large numbers.
13059 Instead, simply match F[0-9]+, which is what is wanted anyway.
13061 * alloc.c: Remove unportable assumptions about struct layout.
13062 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
13063 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
13064 (allocate_vectorlike, make_pure_vector): Use the new macros,
13065 plus offsetof, to remove unportable assumptions about struct layout.
13066 These assumptions hold on all porting targets that I know of, but
13067 they are not guaranteed, they're easy to remove, and removing them
13068 makes further changes easier.
13070 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
13071 This doesn't fix a bug but makes the code clearer.
13072 (string_overrun_cookie): Now const. Use initializers that
13073 don't formally overflow signed char, to avoid warnings.
13074 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
13075 can cause Emacs to crash when string overrun checking is enabled.
13076 (allocate_buffer): Don't assume sizeof (struct buffer) is a
13077 multiple of sizeof (EMACS_INT); it need not be, if
13078 alignof(EMACS_INT) < sizeof (EMACS_INT).
13079 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

13114 * doprnt.c (doprnt): Document the set of format control sequences
13115 supported by the function. Use SAFE_ALLOCA instead of always
13118 * eval.c (verror): Don't limit the buffer size at size_max-1, that
13119 is one byte too soon. Don't use xrealloc; instead xfree and

13131 docstring. Start callback support.
13132 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
13133 unless a fatal error occurred. Call gnutls_alert_send_appropriate

13237 codepoint of an invalid character, to avoid displaying a bogus
13240 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
13241 `error', not SYMBOL_NAME itself.
13243 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
13244 character arguments to `error'.
13246 * charset.c (check_iso_charset_parameter): Fix incorrect argument
13247 to `error' in error message about FINAL_CHAR argument. Make sure
13248 FINAL_CHAR is a character, and use %c when it is passed as
13249 argument to `error'.
13251 2011-04-23 Eli Zaretskii <eliz@gnu.org>
13253 * s/ms-w32.h (localtime): Redirect to sys_localtime.
13255 * w32.c: Include <time.h>.

13319 * dispextern.h (struct redisplay_interface): Rename param
13320 to avoid shadowing.
13321 * termhooks.h (struct terminal): Likewise.

13438 * nsfont.m: Fixed bugs in ns_get_family and
13439 ns_descriptor_to_entity that were caused by using free to
13440 deallocate memory blocks that were allocated by xmalloc (via
13441 xstrdup). This caused Emacs to crash when compiled with
13442 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
13443 --enable-checking=xmallocoverrun). xfree is now used to
13444 deallocate these memory blocks.

13460 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
13461 (emacs_read, emacs_write): Use it.
13462 * process.c (send_process): Adjust to the new signatures of
13463 emacs_write and emacs_gnutls_write. Do not attempt to store
13464 a byte offset into an 'int'; it might overflow.

13941 position of the scroll margin if the window start point w->startp
13942 is outside the buffer's accessible region. (Bug#8468)
13944 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13946 Fix write-region and its subroutines for buffers > 2GB.
13947 * fileio.c (a_write, e_write): Modify declaration of arguments and
13948 local variables to support buffers larger than 2GB.
13949 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13951 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13952 argument, local variables, and return value.
13954 * lisp.h: Update prototypes of emacs_write and emacs_read.
13956 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13958 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13960 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13962 Fix more problems found by GCC 4.6.0's static checks.
13964 * xdisp.c (vmessage): Use a better test for character truncation.
13966 * charset.c (load_charset_map): <, not <=, for optimization,
13967 and to avoid potential problems with integer overflow.
13968 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13969 * casetab.c (set_identity, shuffle): Likewise.
13970 * editfns.c (Fformat): Likewise.
13971 * syntax.c (skip_chars): Likewise.
13973 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13974 This also lets GCC 4.6.0 generate slightly better loop code.
13976 * callint.c (Fcall_interactively): <, not <=, for optimization.
13977 (Fcall_interactively): Count the number of arguments produced,
13978 not the number of arguments given. This is simpler and lets GCC
13979 4.6.0 generate slightly better code.
13981 * ftfont.c: Distingish more carefully between FcChar8 and char.
13982 The previous code passed unsigned char * to a functions like
13983 strlen and xstrcasecmp that expect char *, which does not
13984 conform to the C standard.
13985 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13986 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13987 char * when the C standard requires it.
13989 * keyboard.c (read_char): Remove unused var.
13991 * eval.c: Port to Windows vsnprintf (Bug#8435).
13992 Include <limits.h>.
13993 (SIZE_MAX): Define if the headers do not.
13994 (verror): Do not give up if vsnprintf returns a negative count.
13995 Instead, grow the buffer. This ports to Windows vsnprintf, which
13996 does not conform to C99. Problem reported by Eli Zaretskii.
13997 Also, simplify the allocation scheme, by avoiding the need for
13998 calling realloc, and removing the ALLOCATED variable.
14000 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
14002 Remove invocations of doprnt, as Emacs now uses vsnprintf.
14003 But keep the doprint source code for now, as we might revamp it
14004 and use it again (Bug#8435).
14005 * lisp.h (doprnt): Remove.
14006 * Makefile.in (base_obj): Remove doprnt.o.
14007 * deps.mk (doprnt.o): Remove.
14009 error: Print 32- and 64-bit integers portably (Bug#8435).
14010 Without this change, on typical 64-bit hosts error ("...%d...", N)
14011 was used to print both 32- and 64-bit integers N, which relied on
14012 undefined behavior.
14013 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
14014 * lisp.h (error, verror): Mark as printf-like functions.
14015 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
14016 Report overflow in size calculations when allocating printf buffer.
14017 Do not truncate output string at its first null byte.
14018 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
14019 Truncate the output at a character boundary, since vsnprintf does not
14021 * charset.c (check_iso_charset_parameter): Convert internal
14022 character to string before calling 'error', since %c now has the
14024 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
14025 overflow when computing char to be passed to 'error'. Do not
14026 pass Lisp_Object to 'error'; pass the integer instead.
14027 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
14028 formatted with plain %d.
14030 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
14032 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
14034 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
14036 * xterm.c (x_catch_errors): Remove duplicate declaration.
14038 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
14040 * xdisp.c, lisp.h (message_nolog): Remove; unused.
14042 2011-04-10 Jim Meyering <meyering@redhat.com>
14044 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
14045 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
14046 return ssize_t not "int", and use size_t as the buffer length.
14047 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
14048 * gnutls.h: Update declarations.
14049 * process.c (read_process_output): Use ssize_t, to match.
14050 (send_process): Likewise.
14052 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14054 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
14056 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14058 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
14059 Use unsigned char, to match FcChar8 type definition.
14061 * xterm.c (handle_one_xevent):
14062 * xmenu.c (create_and_show_popup_menu):
14063 * xselect.c (x_decline_selection_request)
14064 (x_reply_selection_request): Avoid type-punned deref of X events.
14066 2011-04-09 Eli Zaretskii <eliz@gnu.org>
14068 Fix some uses of `int' instead of EMACS_INT.
14069 * search.c (string_match_1, fast_string_match)
14070 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
14071 (scan_buffer, find_next_newline_no_quit)
14072 (find_before_next_newline, search_command, Freplace_match)
14073 (Fmatch_data): Make some `int' variables be EMACS_INT.
14075 * xdisp.c (display_count_lines): 3rd argument and return value now
14076 EMACS_INT. All callers changed.
14077 (pint2hrstr): Last argument is now EMACS_INT.
14079 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
14080 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
14081 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
14082 (decode_coding_utf_16, decode_coding_emacs_mule)
14083 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
14084 (decode_coding_ccl, decode_coding_charset)
14085 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
14086 (decode_coding_iso_2022, decode_coding_emacs_mule)
14087 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
14088 <char_offset, last_offset>: Declare EMACS_INT.
14089 (encode_coding_utf_8, encode_coding_utf_16)
14090 (encode_coding_emacs_mule, encode_invocation_designation)
14091 (encode_designation_at_bol, encode_coding_iso_2022)
14092 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
14093 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
14095 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
14096 (encode_invocation_designation): Last argument P_NCHARS is now
14098 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
14099 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
14101 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
14104 * ccl.c (Fccl_execute_on_string): Declare some variables
14107 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
14109 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
14111 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
14113 * process.c (Fformat_network_address): Doc fix.
14115 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
14117 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
14119 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
14121 * keyboard.c (read_char): Call Lisp function help-form-show,
14122 instead of using internal_with_output_to_temp_buffer.
14123 (Qhelp_form_show): New var.
14124 (syms_of_keyboard): Use DEFSYM macro.
14126 * print.c (internal_with_output_to_temp_buffer): Function deleted.
14128 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
14130 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
14132 * process.c (Flist_processes): Remove to Lisp.
14133 (list_processes_1): Delete.
14135 2011-04-06 Eli Zaretskii <eliz@gnu.org>
14137 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
14139 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
14141 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
14143 Fix more problems found by GCC 4.6.0's static checks.
14145 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
14147 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
14149 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
14151 * xdisp.c (vmessage): Mark as a printf-like function.
14153 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
14155 * sound.c (sound_warning): Don't crash if arg contains a printf format.
14157 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
14158 printf-like functions.
14159 (tiff_load): Add casts to remove these marks before passing them
14160 to system-supplied API.
14162 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14164 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14165 This avoids several warnings with gcc -Wstrict-overflow.
14166 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14167 directly, rather than having caller test rule sign. This avoids
14168 some unnecessary tests.
14169 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14170 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14171 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14173 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14174 (xfont_open): Avoid unnecessary tests.
14176 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14178 * composite.h, composite.c (composition_gstring_put_cache):
14179 Use EMACS_INT, not int, for length.
14181 * composite.h (COMPOSITION_DECODE_REFS): New macro,
14182 breaking out part of COMPOSITION_DECODE_RULE.
14183 (COMPOSITION_DECODE_RULE): Use it.
14184 * composite.c (get_composition_id): Remove unused local vars,
14185 by using the new macro.
14187 * textprop.c (set_text_properties_1): Change while to do-while,
14188 since the condition is always true at first.
14190 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14191 (interval_deletion_adjustment): Return unsigned value.
14194 * process.c (list_processes_1, create_pty, read_process_output):
14195 (exec_sentinel): Remove vars that were set but not used.
14196 (create_pty): Remove unnecessary "volatile"s.
14197 (Fnetwork_interface_info): Avoid possibility of int overflow.

14204 (update_syntax_table): Use unsigned instead of int.
14206 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
14207 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
14208 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
14210 * print.c (print_error_message): Avoid int overflow.
14212 * font.c (font_list_entities): Redo for clarity,
14213 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14215 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14216 (font_score): Avoid potential overflow in diff calculation.
14218 * fns.c (substring_both): Remove var that is set but not used.
14219 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14221 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14223 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14224 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14225 can always succeed if overflow has undefined behavior.
14227 * search.c (boyer_moore, wordify): Remove vars set but not used.
14228 (wordify): Omit three unnecessary tests.
14230 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
14231 All callers changed. This avoids the need for an unused var.
14233 * casefiddle.c (casify_region): Remove var that is set but not used.
14235 * dired.c (file_name_completion): Remove var that is set but not used.
14237 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
14239 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
14240 (Finsert_file_contents): Remove unnecessary code checking fd.
14242 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14243 Check for integer overflow on size calculations.
14245 * buffer.c (Fprevious_overlay_change): Remove var that is set
14248 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14249 Remove vars that are set but not used.
14250 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
14251 (timer_check_2): Mark vars as initialized.
14253 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
14255 * image.c (lookup_image): Remove var that is set but not used.
14256 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
14258 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14259 that are set but not used.
14261 * xfns.c (make_invisible_cursor): Don't return garbage
14262 if XCreateBitmapFromData fails (Bug#8410).
14264 * xselect.c (x_get_local_selection, x_handle_property_notify):
14265 Remove vars that are set but not used.
14267 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

14277 (map_tty_color) [!defined MSDOS]: Likewise.
14279 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14281 * coding.c: Remove vars that are set but not used.
14282 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14283 All callers changed.
14284 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
14285 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
14286 (decode_coding_charset): Remove vars that are set but not used.
14288 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
14289 that is set but not used.
14291 * print.c (print_object): Remove var that is set but not used.
14293 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14294 The gnulib version avoids calling malloc in the usual case,
14295 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14296 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14297 * filelock.c (current_lock_owner): Likewise.
14298 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14299 * sysdep.c: Include allocator.h, careadlinkat.h.
14300 (emacs_no_realloc_allocator): New static constant.
14301 (emacs_readlink): New function.
14302 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14303 ../lib/careadlinkat.h.
14305 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14307 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14308 first non-nil return value).

14312 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
14313 if not defined (Bug#8403).

14322 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
14323 and thereabouts. All callers changed.
14324 (get_per_char_metric): Remove parameter `f', unused since
14325 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

14329 do not dereference NULL upon failed strdup
14330 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
14331 (ns_get_family): Likewise.
14333 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14335 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.

14372 (Fcommandp): Handle closures.
14373 (Feval): New `lexical' arg.
14374 (eval_sub): New function extracted from Feval. Use it almost

14406 * xdisp.c (SCROLL_LIMIT): New macro.
14407 (try_scrolling): Use it when setting scroll_limit.
14408 Limit scrolling to 100 screen lines.
14409 (redisplay_window): Even when falling back on "recentering",
14410 position point in the window according to scroll-conservatively,
14411 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14413 (try_scrolling): When point is above the window, allow searching
14414 as far as scroll_max, or one screenful, to compute vertical
14415 distance from PT to the scroll margin position. This prevents
14416 try_scrolling from unnecessarily failing when
14417 scroll-conservatively is set to a value slightly larger than the
14418 window height. Clean up the case of PT below the margin at bottom
14419 of window: scroll_max can no longer be INT_MAX. When aggressive
14420 scrolling is in use, don't let point enter the opposite scroll
14421 margin as result of the scroll.
14422 (syms_of_xdisp) <scroll-conservatively>: Document the
14423 threshold of 100 lines for never-recentering scrolling.
14425 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14427 * dispextern.h (move_it_by_lines):
14428 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
14429 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
14430 (message_log_check_duplicate): Remove parameters `prev_bol' and
14431 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14432 (redisplay_internal): Remove parameter `preserve_echo_area',
14433 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14435 * indent.c (Fvertical_motion):
14436 * window.c (window_scroll_pixel_based, Frecenter):
14437 Don't pass `need_y_p' to `move_it_by_lines'.
14439 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14441 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14442 steal a few bits to be more compact.
14443 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14444 Remove unneeded casts.
14446 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14448 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14450 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14451 binding" message (bug#7967).
14453 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14455 Fix more problems found by GCC 4.6.0's static checks.
14457 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14458 Remove unused local var.
14460 * editfns.c (Fmessage_box): Remove unused local var.
14462 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14463 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14464 Omit unused local vars.
14465 * window.c (shrink_windows): Omit unused local var.
14466 * menu.c (digest_single_submenu): Omit unused local var.
14467 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14468 Omit unused local var.
14470 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14471 Don't assume string length fits in int.
14472 (keyremap_step, read_key_sequence): Use size_t for sizes.
14473 (read_key_sequence): Don't check last_real_key_start redundantly.
14475 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14476 instead of alloca (Bug#8344).
14478 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14479 (Fbacktrace_frame): Don't assume nframes fits in int.
14481 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14483 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14486 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14488 * cm.c (calccost): Turn while-do into do-while, for clarity.
14490 * keyboard.c (syms_of_keyboard): Use the same style as later
14491 in this function when indexing through an array. This also
14492 works around GCC bug 48267.
14494 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14496 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14498 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14499 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14501 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14502 This avoids undefined behavior on integer overflow, and is a bit
14503 more convenient anyway since it is compared to a size_t variable.
14505 Variadic C functions now count arguments with size_t, not int.
14506 This avoids an unnecessary limitation on 64-bit machines, which
14507 caused (substring ...) to crash on large vectors (Bug#8344).
14508 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14509 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

14513 * editfns.c (general_insert_function): Likewise.
14514 * eval.c (struct backtrace.nargs, interactive_p)
14515 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14516 (funcall_lambda, mark_backtrace): Likewise.
14517 * fns.c (concat): Likewise.
14518 * frame.c (x_set_frame_parameters): Likewise.
14519 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14520 0 if not found, not -1. All callers changed.
14522 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14523 (stack_copy_size): Now size_t, not int.
14524 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14526 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14528 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14529 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14530 All callers changed.
14532 * lisp.h (multibyte_char_to_unibyte):
14533 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14534 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14535 * character.h (CHAR_TO_BYTE8):
14536 * cmds.c (internal_self_insert):
14537 * editfns.c (general_insert_function):
14538 * keymap.c (push_key_description):
14539 * search.c (Freplace_match):
14540 * xdisp.c (message_dolog, set_message_1): All callers changed.
14542 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14544 * keyboard.c (safe_run_hook_funcall): New function.
14545 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14546 don't set the hook to nil, but remove the offending function instead.
14547 (Qcommand_hook_internal): Remove, unused.
14548 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14549 Vcommand_hook_internal.
14551 * eval.c (enum run_hooks_condition): Remove.
14552 (funcall_nil, funcall_not): New functions.
14553 (run_hook_with_args): Call each function through a `funcall' argument.
14554 Remove `cond' argument, now redundant.
14555 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14556 (Frun_hook_with_args_until_failure): Adjust accordingly.
14557 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14559 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14561 * dispextern.h (string_buffer_position): Remove declaration.
14563 * print.c (strout): Remove parameter `multibyte', unused since
14564 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14566 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14567 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14568 All callers changed.
14570 * w32.c (_wsa_errlist): Use braces for struct initializers.
14572 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14573 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14574 All callers changed.
14575 (string_buffer_position): Likewise. Also, make static (it's never
14576 used outside xdisp.c).
14577 (cursor_row_p): Remove parameter `w', unused since
14578 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14580 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14581 All callers changed.
14583 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14585 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

14591 (ns_update_auto_hide_menu_bar): New functions.
14592 (ns_update_begin): Call ns_update_auto_hide_menu_bar.
14593 (applicationDidBecomeActive): Call ns_update_auto_hide_menu_bar and

14596 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14598 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14600 * nsmenu.m (runDialogAt): Remove argument to timer_check.
14602 2011-03-27 Glenn Morris <rgm@gnu.org>
14604 * syssignal.h: Replace RETSIGTYPE with void.
14605 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
14606 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
14607 Replace SIGTYPE with void everywhere.
14608 * s/usg5-4-common.h (SIGTYPE): Remove definition.
14609 * s/template.h (SIGTYPE): Remove commented out definition.
14611 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14613 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14614 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14616 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14618 * w32.c (read_unc_volume): Use parameter `henum', instead of
14619 global variable `wget_enum_handle'.
14621 * keymap.c (describe_vector): Remove parameters `indices' and
14622 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14625 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
14627 * keyboard.c (timer_check): Remove parameter `do_it_now',
14628 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
14629 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
14630 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
14632 * keyboard.c (read_char):
14633 * w32menu.c (w32_menu_display_help):
14634 * xmenu.c (show_help_event, menu_help_callback):
14635 Adjust calls to `show_help_echo'.
14637 * gtkutil.c (xg_maybe_add_timer):
14638 * keyboard.c (readable_events):
14639 * process.c (wait_reading_process_output):
14640 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14642 * insdel.c (adjust_markers_gap_motion):
14643 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
14644 (gap_left, gap_right): Don't call it.
14646 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

14692 * w32term.c (x_set_glyph_string_clipping):
14693 Don't pass uninitialized region to CombineRgn.
14695 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
14697 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

14717 2011-03-23 Julien Danjou <julien@danjou.info>
14719 * term.c (Fsuspend_tty, Fresume_tty):
14720 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14721 * window.c (temp_output_buffer_show):
14722 * insdel.c (signal_before_change):
14723 * frame.c (Fhandle_switch_frame):
14724 * fileio.c (Fdo_auto_save):
14725 * emacs.c (Fkill_emacs):
14726 * editfns.c (save_excursion_restore):
14727 * cmds.c (internal_self_insert):
14728 * callint.c (Fcall_interactively):
14729 * buffer.c (Fkill_all_local_variables):
14730 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14732 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14733 unconditionally since it does the check itself.
14735 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14737 Fix more problems found by GCC 4.5.2's static checks.
14739 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14740 the first time through the loop, since we know p0 < p1 then.
14741 This also avoids a gcc -Wstrict-overflow warning.
14743 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14744 leading to a memory leak, possible in functions like
14745 load_charset_map_from_file that can allocate an unbounded number
14746 of objects (Bug#8318).
14748 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14749 that could (at least in theory) be that large.
14751 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14752 This is less likely to overflow, and avoids undefined behavior if
14753 overflow does occur. All callers changed. Use strtoul to scan
14754 for the unsigned long integer.
14755 (pint2hrstr): Simplify and tune code slightly.
14756 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14758 * scroll.c (do_scrolling): Work around GCC bug 48228.
14759 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
14761 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
14762 This also avoids a warning with gcc -Wstrict-overflow.
14763 (validate_x_resource_name): Simplify count usage.
14764 This also avoids a warning with gcc -Wstrict-overflow.
14766 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14769 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14771 * process.c (Fmake_network_process): Use socklen_t, not int,
14772 where POSIX says socklen_t is required in portable programs.
14773 This fixes a porting bug on hosts like 64-bit HP-UX, where
14774 socklen_t is wider than int (Bug#8277).
14775 (Fmake_network_process, server_accept_connection):
14776 (wait_reading_process_output, read_process_output):
14779 * process.c: Rename or move locals to avoid shadowing.
14780 (list_processes_1, Fmake_network_process):
14781 (read_process_output_error_handler, exec_sentinel_error_handler):
14782 Rename or move locals.
14783 (Fmake_network_process): Define label "retry_connect" only if needed.
14784 (Fnetwork_interface_info): Fix pointer signedness.
14785 (process_send_signal): Add cast to avoid pointer signedness problem.
14786 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14787 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14789 Make tparam.h and terminfo.c consistent.
14790 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14791 Include tparam.h instead, since it declares them.
14792 * cm.h (PC): Remove extern decl; tparam.h now does this.
14793 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14794 * terminfo.c: Include tparam.h, to check interfaces.
14795 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14796 (tparam): Adjust signature to match interface in tparam.h;
14797 this removes some undefined behavior. Check that outstring and len
14798 are zero, which they always are with Emacs.
14799 * tparam.h (PC, BC, UP): New extern decls.
14801 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14802 (xftfont_open): Rename locals to avoid shadowing.
14804 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14805 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14806 (OTF_TAG_SYM): Omit macro if not needed.
14807 (ftfont_list): Remove unused local.
14808 (get_adstyle_property, ftfont_pattern_entity):
14809 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
14810 Rename locals to avoid shadowing.
14812 * xfont.c (xfont_list_family): Mark var as initialized.
14814 * xml.c (make_dom): Now static.
14816 * composite.c (composition_compute_stop_pos): Rename local to
14818 (composition_reseat_it): Remove unused locals.
14819 (find_automatic_composition, composition_adjust_point): Likewise.
14820 (composition_update_it): Mark var as initialized.
14821 (find_automatic_composition): Mark vars as initialized,
14822 with a FIXME (Bug#8290).
14824 character.h: Rename locals to avoid shadowing.
14825 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14826 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14827 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14828 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14829 to avoid shadowing.

14848 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14850 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14851 clobbering (Bug#8298).
14852 * sysdep.c (sys_subshell): Likewise.
14853 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14855 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14856 This should get cleaned up, so that child_setup has the
14857 same signature on all platforms.
14859 * callproc.c (call_process_cleanup): Now static.
14860 (relocate_fd): Rename locals to avoid shadowing.
14862 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

14990 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14991 some of which prompt warnings from gcc -Wbad-function-cast.
14992 (Fformat_time_string, Fencode_time, Finsert_char):

15021 (Fmemory_limit): Cast sbrk's returned value to char *.
15023 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

15026 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
15028 Use functions, not macros, for up- and down-casing (Bug#8254).
15029 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15030 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
15031 to use the following functions instead of these macros.
15032 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
15033 EMACS_INT, since callers assume the returned value fits in int.
15034 (upcase1): Likewise, for UPCASE_TABLE.
15035 (uppercasep, lowercasep, upcase): New static inline functions.
15036 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

15046 (regex_compile, re_match_2_internal): Mark locals as initialized.
15047 (RETALLOC_IF): Define only if needed.
15048 (WORDCHAR_P): Likewise. This one is never needed, but is used
15049 only in a comment talking about a compiler bug, so put inside
15050 the #if 0 of that comment.
15051 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
15052 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

15078 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
15079 New macros, so that the caller can use some names other than
15080 gcpro1, gcpro2, etc.
15081 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15083 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15084 argument, for consistency with GCPRO2_VAR, etc: it is now the
15085 prefix of the variable, not the variable itself. All uses
15087 * dired.c (directory_files_internal, file_name_completion):
15088 Rename locals to avoid shadowing.
15090 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15091 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15092 dired.c's scmp function, had undefined behavior.
15093 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15094 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15095 * buffer.h: ... to here, because these macros use current_buffer,
15096 and the new implementation with inline functions needs to have
15097 current_buffer in scope now, rather than later when the macros
15099 (downcase, upcase1): New static inline functions.
15100 (DOWNCASE, UPCASE1): Reimplement using these functions.
15101 This avoids undefined behavior in expressions like
15102 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15103 from race conditions in accessing the global variables
15104 case_temp1 and case_temp2.
15105 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15106 * lisp.h (case_temp1, case_temp2): Remove their decls.
15107 * character.h (ASCII_CHAR_P): Move from here ...
15108 * lisp.h: ... to here, so that the inline functions mentioned
15109 above can use them.
15111 * dired.c (directory_files_internal_unwind): Now static.
15113 * fileio.c (file_name_as_directory, directory_file_name):

15116 (file_name_as_directory): Use const pointers when appropriate.
15117 (Fexpand_file_name): Likewise. In particular, newdir might
15118 point at constant storage, so make it a const pointer.
15119 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
15120 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15122 (Fset_file_times, Finsert_file_contents, auto_save_error):
15123 Rename locals to avoid shadowing.

15127 to avoid shadowing.
15129 * marker.c (bytepos_to_charpos): Remove; unused.
15131 * lisp.h (verify_bytepos, count_markers): New decls,
15132 so that gcc does not warn that these functions aren't declared.
15134 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
15135 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
15136 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
15137 (copy_text): Remove unused local var.
15139 * filelock.c (within_one_second): Now static.
15140 (lock_file_1): Rename local to avoid shadowing.
15142 * buffer.c (fix_overlays_before): Mark locals as initialized.
15143 (fix_start_end_in_overlays): Likewise. This function should be
15144 simplified by using pointers-to-pointers, but that's a different
15146 (switch_to_buffer_1): Now static.
15147 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15148 (report_overlay_modification): Rename locals to avoid shadowing.
15150 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
15151 Fix pointer signedness issue.
15152 (sys_subshell): Mark local as volatile if checking for lint,
15153 to suppress a gcc -Wclobbered warning that does not seem to be right.
15154 (MAXPATHLEN): Define only if needed.
15156 * process.c (serial_open, serial_configure): Move decls from here ...
15157 * systty.h: ... to here, so that they can be checked.
15159 * fns.c (get_random, seed_random): Move extern decls from here ...
15160 * lisp.h: ... to here, so that they can be checked.
15162 * sysdep.c (reset_io): Now static.
15163 (wait_for_termination_signal): Remove; unused.
15165 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
15166 (copy_keymap_item, append_key, push_text_char_description):
15168 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
15169 (DENSE_TABLE_SIZE): Remove; unused.
15170 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
15171 (describe_map_tree):
15172 Rename locals to avoid shadowing.
15174 * keyboard.c: Declare functions static if they are not used elsewhere.

15259 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
15260 These macros can no longer be used for assignment.
