636 Remove the code that deletes site-lisp subdirectories from the default
637 value of EMACSLOADPATH, as it is no longer needed.
638 (check_windows_init_file): Now external, not static.

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

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

718 headers (most versions of MinGW w32api don't).
719 (get_security_info, create_symbolic_link)
720 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
722 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

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

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

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

798 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
800 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
801 This how ASET and AREF are supposed to work, and makes
802 it easier to think about future improvements. See
803 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
804 * charset.h (set_charset_attr): New function.

1185 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
1186 (w32_kbd_patch_key, key_event): Use the codepage returned by

1219 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
1220 enumeration constants, as PURE and HEAP are too general, and clash
1221 with other headers and sources, such as gmalloc.c and the
1222 MS-Windows system headers. All users changed.
1224 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
1226 Revert last save_excursion_save and save_excursion_restore changes.
1227 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

1243 is an integer literal.
1244 (xgetint): Simplify expression.
1245 * alloc.c (gdb_make_enums_visible): New constant. This ports to

1247 Zaretskii in <http://bugs.gnu.org/12036#13>.
1248 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
1249 needed now that we have gdb_make_enums_visible.

1294 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
1295 emacs.c, as this is a more-suitable home. Had this been done earlier
1296 the fix for 12036 would have avoided some of the problems noted in
1297 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
1298 would have been more obvious.
1299 * emacs.c: Do not include <verify.h>; no longer needed.
1300 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

1308 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1309 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1310 not be usable in #if. This simplifies things.
1312 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1314 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

1319 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1320 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1321 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1322 Adjust to changes in lisp.h and emacs.c, by using
1323 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1324 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1325 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

1327 instead of gdb_valbits.
1328 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
1329 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
1330 instead of gdb_array_mark_flag.
1331 (xboolvector): Get size from $->size, not $->header.size.
1332 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1333 (xreload, hook-run, hookpost-run): Remove.
1334 * emacs.c: Include <verify.h>.
1335 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1336 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
1338 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
1339 (gdb_USE_LSB_TAG): New enum constants.
1340 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1341 Also define these as enum constants, so they're visible to GDB.

1343 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

1347 Now enum constants, not macros, so they're visible to GDB.
1348 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1349 more convenient now. All uses changed.
1350 (VALMASK) [USE_LSB_TAG]: Also define in this case.

1358 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
1360 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
1361 add argument, tune behavior, and adjust all callers.
1363 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
1365 Use typedef for EMACS_INT, EMACS_UINT.
1366 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather

2232 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
2233 Prefer snprintf to strncpy.
2234 * nsterm.m (ns_term_init):
2235 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2236 * nsterm.m (ns_term_init):
2237 Avoid the need for strncpy, by using build_string or
2238 make_unibyte_string directly. Use dtoastr, not snprintf.
2239 * process.c (Fmake_network_process): Diagnose service names that
2240 are too long, rather than silently truncating them or creating

2274 provides a better opportunity to optimize away calls to strlen when
2275 the function is called with compile-time constant argument.
2276 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2277 argument, adjust users accordingly. Use build_pure_c_string where
2279 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2280 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
2281 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
2283 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2285 Avoid calls to strlen in miscellaneous functions.
2286 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
2287 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
2288 * lread.c (openp): Likewise.
2290 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2292 Avoid calls to strlen in path processing functions.
2293 * fileio.c (file_name_as_directory): Add comment. Change to add
2294 srclen argument and return the length of result. Adjust users
2296 (directory_file_name): Fix comment. Change to add srclen argument,
2297 swap 1st and 2nd arguments to obey the common convention.
2298 Adjust users accordingly.
2299 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2301 2012-07-10 Glenn Morris <rgm@gnu.org>
2303 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
2304 Move PENDING_OUTPUT_COUNT definition to configure.
2306 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
2307 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
2308 * s/gnu.h (DATA_START): Move definitions to configure.
2310 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2311 We include usg5-4-common.h, which defines them both.
2313 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2314 O_RDONLY already includes it).
2316 Stop ns builds setting the EMACSLOADPATH environment variable.
2317 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2318 Now it does not set EMACSLOADPATH, just returns the load-path string.
2319 * nsterm.h: Update accordingly.
2320 * lread.c [HAVE_NS]: Include nsterm.h.
2321 (init_lread) [HAVE_NS]: Use ns_load_path.

2324 2012-07-09 Glenn Morris <rgm@gnu.org>
2326 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2327 since the included bsd-common.h does so.
2329 Stop ns builds setting the EMACSPATH environment variable.
2330 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2331 (ns_init_paths): Do not set EMACSPATH.
2332 * nsterm.h (ns_exec_path): Add it.
2333 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2336 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2338 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2340 * process.c (wait_reading_process_output): 'waitchannels' was unset
2341 when read_kbd || !NILP (wait_for_cell); fix this.
2343 Add GCC-style 'const' attribute to functions that can use it.
2344 * character.h (char_resolve_modifier_mask):
2345 * keyboard.h (make_ctrl_char):
2346 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

2353 Declare the dummy function with ATTRIBUTE_CONST.
2354 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2355 Add decls with ATTRIBUTE_CONST.
2357 Minor improvements to make_formatted_string.
2358 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2359 where int is good enough, as vsprintf returns an int.
2360 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2362 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2364 Use make_formatted_string to avoid double length calculation.
2365 * lisp.h (make_formatted_string): New prototype.
2366 * alloc.c (make_formatted_string): New function.
2367 * buffer.c (Fgenerate_new_buffer_name): Use it.

2371 * frame.c (make_terminal_frame, set_term_frame_name)
2372 (x_report_frame_params): Likewise.
2373 * image.c (gs_load): Likewise.

2389 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2391 Move marker debugging code under MARKER_DEBUG.
2392 * marker.c (MARKER_DEBUG): Move marker debugging code under
2393 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2394 for bootstrap with --enable-checking (~3x slowdown reported
2395 by Juanma Barranquero <lekktu@gmail.com>).
2396 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2398 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2400 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2401 See <http://bugs.gnu.org/11825#29>.
2403 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2405 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2406 has no font, use the frame's font. (Bug#11813)
2407 (display_line): Add commentary about displaying truncation glyphs
2409 (produce_special_glyphs): Move here from term.c.
2411 * term.c (produce_special_glyphs): Move to xdisp.c.
2413 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2416 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2418 * xdisp.c (display_line): Avoid warning about implicit declaration
2421 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2423 * lisp.h: Remove empty conditional.
2425 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2427 * lread.c (load_path_check): Now static.
2429 Fix some minor --with-ns problems found by static checking.
2430 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2431 (x_set_font) [!HAVE_X_WINDOWS]:
2432 * image.c (xpm_load_image) [HAVE_NS]:
2433 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2434 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2435 Remove unused local.
2436 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2437 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2438 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2439 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2440 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2441 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2442 Fix pointer signedness problem.
2443 * xfaces.c (FRAME_X_FONT_TABLE):
2444 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2446 2012-07-07 Glenn Morris <rgm@gnu.org>
2448 * lread.c (load_path_check): New function, split from init_lread.
2449 (init_lread): Reorganize. Motivation:
2450 If EMACSLOADPATH is set, check/warn about that rather than the
2451 defaults, which we are not going to use. Hence we can remove
2452 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2453 Don't warn if site-lisp directories are missing.
2454 If not installed, start from a blank load-path, since
2455 PATH_LOADSEARCH refers to the eventual installation directories.
2457 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2459 Support truncation and continuation glyphs on GUI frames, when
2460 fringes are disabled. (Bug#11832)
2461 * xdisp.c (init_iterator): Get dimensions of truncation and
2462 continuation glyphs even if on GUI frames.
2463 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2464 or both, are absent.
2465 (start_display, move_it_in_display_line_to): Handle the case of a
2466 GUI frame without a fringe to display continuation or truncation
2468 (insert_left_trunc_glyphs): Support GUI frames: make sure
2469 truncation glyphs overwrite enough glyphs from the current line to
2470 have sufficient space in pixels.
2471 (display_line): Support truncation and continuation glyphs on GUI
2472 frames. If some spare pixels are left on the line after inserting
2473 the truncation glyphs, fill that space with a stretch glyph of a
2474 suitably computed width.
2476 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2477 produce_glyphs, to support GUI sessions.
2479 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2481 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2483 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2485 Do not require float-time's arg to fit in time_t (Bug#11825).
2486 This works better on hosts where time_t is unsigned, and where
2487 float-time is applied to the (negative) difference between two times.
2488 * editfns.c (decode_time_components): Last arg is now double *,
2489 not int *, and means to store all the result as a double, without
2490 worrying about whether the seconds part fits in time_t.
2491 All callers changed.
2492 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2493 All callers changed.
2494 (Ffloat_time): Do not fail merely because the specified time falls
2495 outside of time_t range.
2497 2012-07-07 Glenn Morris <rgm@gnu.org>
2499 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2505 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2506 Update dependencies.
2508 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2510 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2512 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

2514 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2515 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2516 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

2519 * xfont.c (compare_font_names): Redo to omit the need for casts.
2521 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2523 * xfns.c (Fx_change_window_property): Doc fix.
2524 * w32fns.c (Fx_change_window_property): Doc fix.
2526 * w32fns.c (Fx_window_property): Accept the same arguments as the
2527 X Windows version. Doc fix.
2528 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2530 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2531 Eli Zaretskii <eliz@gnu.org>
2533 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2534 Windows-specific code from nt/config.nt moved here.
2535 Obsolete settings removed.
2537 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2539 * process.c: Avoid unnecessary calls to gettime.
2540 (wait_reading_process_output): Don't get the time of day
2541 when gobbling data immediately and not waiting, as there's no need
2542 for it in that case. This removes a FIXME.
2544 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2546 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2547 is defined (Bug#11768).

2552 * marker.c (byte_char_debug_check): Do not perform the check
2553 if buffer is not multibyte.
2554 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2555 Call byte_char_debug_check with correct arguments.
2557 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2559 Compile marker debugging code only if ENABLE_CHECKING is defined.
2560 * marker.c (byte_char_debug_check, count_markers):
2561 Use only if ENABLE_CHECKING is defined.
2562 (byte_debug_flag): Remove.
2563 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2564 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2566 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2568 Avoid code repetition in marker-related functions.
2569 * marker.c (attach_marker): New function.
2570 (Fset_marker, set_marker_restricted, set_marker_both)
2571 (set_marker_restricted_both): Use it.
2572 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2573 Consistently rename charno to charpos.
2574 (marker_position): Add eassert.
2575 (marker_byte_position): Convert to eassert.

2594 * window.c (save_window_save): Likewise.
2596 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2598 Do not use Fdelete_overlay in delete_all_overlays
2599 to avoid redundant calls to unchain_overlay.
2600 * buffer.c (drop_overlay): New function.
2601 (delete_all_overlays, Fdelete_overlay): Use it.
2602 * minibuf.c (get_minibuffer): Fix comment.

2606 Port to OpenBSD 5.1 amd64.
2607 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2608 This is needed for OpenBSD, and should be harmless on all BSD systems.
2609 Also, include <sys/sysctl.h>, as it should be available on all
2610 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2611 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2612 use p_pid member, not kp_proc.pid.
2614 2012-07-06 Glenn Morris <rgm@gnu.org>
2616 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2618 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

2629 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2631 Omit needless casts involving void * pointers and allocation.
2632 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2633 as the former is more robust if P's type is changed.
2634 Prefer xzalloc to xmalloc + memset 0.
2635 Simplify malloc-or-realloc to realloc.
2636 Don't worry about xmalloc returning a null pointer.
2637 Prefer xstrdup to xmalloc + strcpy.
2638 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2640 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2641 alloca of a constant.
2643 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2645 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2646 hscroll is larger than the line width. Fixes long and futile
2647 looping inside extend_face_to_end_of_line (on a TTY) producing
2648 glyphs that are not needed and thrown away.
2650 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

2678 * xdisp.c (window_hscroll_limited): New function.
2679 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2680 coordinates when window's hscroll is set to insanely large

2746 * fileio.c (time_error_value): Check the right error number.
2747 Problem reported by Troels Nielsen in
2748 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2750 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2752 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2753 This should be fixed in a better way; see Eli Zaretskii in
2754 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2755 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2757 * fileio.c (time_error_value): Rename from special_mtime.
2758 The old name's problems were noted by Eli Zaretskii in
2759 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2761 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2762 This variable's comment says Emacs needs at least one GDB-visible
2763 symbol of type enum pvec_type, to work around GDB problems.
2764 The symbol's value doesn't matter.
2766 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2767 that causes compilation to fail on pre-C99 compilers.
2769 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2771 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2772 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2774 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2776 * buffer.c (init_buffer_once): Fix initialization of
2777 headers for buffer_defaults and buffer_local_symbols.
2778 Reported by Juanma Barranquero <lekktu@gmail.com>.
2780 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2782 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2783 * lisp.h (enum pvec_type): Use fewer bits.
2784 (PSEUDOVECTOR_SIZE_BITS): New constant.
2785 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2786 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2787 change in pvec_type.
2788 (PSEUDOVECTOR_TYPEP): New macro.
2789 (TYPED_PSEUDOVECTORP): Use it.
2790 * fns.c (internal_equal): Adapt code to extract pvectype.
2791 * emacs.c (gdb_pvec_type): Update type.
2792 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2793 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2794 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2795 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2796 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2797 abusing vector->header.next.nbytes.
2798 (live_vector_p): Use PVEC_TYPE.
2799 (mark_object): Adapt code to extract pvectype. Use switch.
2801 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2803 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2804 Tighten new eassert a bit.
2806 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2808 Fix compilation with --enable-gcc-warnings and -O1
2810 * doprnt.c (doprnt): Change type of tem to int, initialize
2811 to avoid compiler warning. Add eassert.
2812 * search.c (simple_search): Initialize match_byte to avoid
2813 compiler warning. Add eassert.
2815 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2817 Avoid weird behavior with large horizontal scrolls.
2818 Without this change, for example, large hscroll values would
2819 mess up Emacs's display on Fedora 15 x86, presumably due to
2820 overflows in int calculations in the display code.
2821 Also, if buffers had long lines, Emacs would freeze.
2822 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2823 (set_window_hscroll): New function, containing the old guts of
2824 Fset_window_hscroll. Return the clipped value.
2825 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2826 This avoids the need to check against PTRDIFF_MAX.
2828 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2830 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2832 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2834 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2836 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2837 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2838 since GCC 4.4.6 issues a bogus warning for them.
2840 Fix bugs in file timestamp newness comparisons.
2841 * fileio.c (Ffile_newer_than_file_p):
2842 * lread.c (Fload): Use full timestamp resolution of files,
2843 not just the 1-second resolution, so that files that are only
2844 slightly newer still count as newer.
2845 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2846 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2848 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2850 * fileio.c: Improve handling of file time marker. (Bug#11852)
2851 (special_mtime): New function.
2852 (Finsert_file_contents, Fverify_visited_file_modtime):
2853 Use it to set special mtime values consistently.
2855 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2857 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2858 marker for non-existing file. (Bug#11852)
2860 2012-07-03 Glenn Morris <rgm@gnu.org>
2862 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2863 and did not make it into globals.h).
2865 2012-07-03 Tom Tromey <tromey@redhat.com>
2867 * window.c (Fset_window_margins, Fset_window_fringes)
2868 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2869 * textprop.c (Fprevious_property_change): No longer static.
2870 * syntax.c (Fsyntax_table_p): No longer static.

2899 * window.h: Remove EXFUNs.

2901 * xterm.h: Remove EXFUN.
2903 2012-07-03 Glenn Morris <rgm@gnu.org>
2905 * lisp.h (Frandom): Make it visible to C.
2906 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2907 buffer for invisible buffers. (Bug#1229)
2909 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2911 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2912 values which aren't power of 2.
2913 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
2914 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2917 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2919 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2921 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2923 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2925 * alloc.c (allocate_vector_block): Remove redundant
2926 calls to mallopt if DOUG_LEA_MALLOC is defined.
2927 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2928 avoid calls to mallopt if zero_vector is returned.
2930 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2932 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2933 is enabled, avoid dereferencing NULL current_sblock if
2936 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2938 Cleanup basic buffer management.
2939 * buffer.h (struct buffer): Change layout to use generic vector
2940 marking code. Fix some comments. Change type of 'clip_changed'
2941 to bitfield. Remove unused #ifndef old.
2942 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2943 (GET_OVERLAYS_AT): Fix indentation.
2944 (for_each_per_buffer_object_at): New macro.
2945 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2947 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2948 * alloc.c (allocate_buffer): Adjust to match new layout of
2949 struct buffer. Fix comment.
2950 (mark_overlay): New function.
2951 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2952 Lisp area of struct buffer.
2953 (mark_object): Use it. Adjust marking of misc objects
2954 and related comments.
2956 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2958 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2959 wrapper that is not needed because the wrapped code is a no-op (zero
2960 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2961 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2963 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2965 * alloc.c (mark_buffer): Simplify. Remove prototype.
2966 (mark_object): Add comment. Reorganize marking of vector-like
2967 objects. Use CHECK_LIVE for all vector-like objects except buffers
2968 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
2969 Avoid redundant calls to mark_vectorlike for bool vectors.
2971 2012-06-30 Glenn Morris <rgm@gnu.org>
2973 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2975 * epaths.in (PATH_SITELOADSEARCH): New.
2976 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2977 This is rather than relying on --enable-locallisppath elements
2978 having "site-lisp" in their names. (Bug#10208#25, 11658)
2980 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2982 * w32proc.c (sys_select): Accept and ignore one more argument.
2984 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2986 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2987 (pselect) [!MS_DOS]: Redirect to sys_select.
2989 * sysdep.c: Don't include dos.h and dosfns.h.
2991 * process.c (sys_select):
2992 * msdos.c (sys_select): Accept one more argument and ignore it.
2994 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2995 adapt data types and code to that.
2998 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2999 which clashes with the gnulib function of the same name.
3001 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3003 * font.c (font_style_to_value, font_style_symbolic)
3004 (font_prop_validate_style): Add type checks for values in
3007 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3009 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3012 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3014 * xdisp.c (try_window_id): Undo last change.
3016 * w32.c (getwd): Adjust commentary about startup_dir.
3017 (init_environment): Always call sys_access, even in non-MSVC
3018 builds. Don't chdir to the directory of the Emacs executable.
3019 This undoes code from 1997 which was justified by the need to
3020 "avoid conflicts when removing and renaming directories". But its
3021 downside was that every relative file name was being interpreted
3022 relative to the directory of the Emacs executable, which can never
3023 be TRT. In particular, it broke sys_access when called with
3024 relative file names.
3025 (sys_access): Map GetLastError to errno.
3027 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3029 * window.h (struct window): Change type of 'fringes_outside_margins'
3030 to bitfield. Fix comment. Adjust users accordingly.
3031 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
3033 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3036 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
3038 * gnutls.c (emacs_gnutls_handshake):
3039 Add QUIT to make the loop interruptible.
3041 2012-06-29 Glenn Morris <rgm@gnu.org>
3043 * charset.c (init_charset): Make lack of etc/charsets fatal.
3045 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3047 * editfns.c (region_limit): Fix type mismatch.
3049 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3051 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3052 undefined. Convert from xassert to eassert.
3053 * nsmenu.m: Convert from xassert to eassert.
3054 * nsterm.m: Likewise.
3056 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3058 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3060 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3062 Avoid integer overflow on scroll-left and scroll-right.
3063 * window.c (HSCROLL_MAX): New macro.
3064 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3065 overflow when requested scroll falls outside ptrdiff_t range.
3067 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3069 * window.h (struct window): Change type of 'hscroll',
3070 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3071 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3072 Adjust users accordingly.
3073 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3074 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3075 from EMACS_INT to ptrdiff_t.
3076 (make_window): Omit redundant initialization.
3078 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
3080 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
3082 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3084 * window.h (struct window): Change type of 'use_time' and
3085 'sequence_number' from Lisp_Object to int.

3147 avoid GCC warning about unused macro.
3149 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3151 * alloc.c (allocate_string): Omit intervals initialization.
3152 * alloc.c (make_uninit_multibyte_string): Initialize intervals
3153 as in make_pure_string and make_pure_c_string.
3155 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3157 * alloc.c (allocate_string): Fix last change.
3159 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

3209 * alloc.c: Remove build_string.
3210 * lisp.h: Define build_string as static inline. This provides
3211 a better opportunity to optimize away calls to strlen when the
3212 function is called with compile-time constant argument.
3213 * image.c (imagemagick_error): Convert to build_string.
3214 * w32proc.c (sys_spawnve): Likewise.

3217 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3219 Use sprintf return value instead of invoking strlen on result.
3220 In the old days this wasn't portable, since some sprintf
3221 implementations returned char *. But they died out years ago and
3222 Emacs already assumes sprintf returns int.
3223 Similarly for float_to_string.
3224 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

3231 * xfns.c (syms_of_xfns):
3232 Use sprintf or float_to_string result to avoid need to call strlen.
3233 * data.c (Fnumber_to_string):

3235 * lisp.h, print.c (float_to_string): Now returns int length.
3236 * term.c (produce_glyphless_glyph):
3237 Use sprintf result rather than recomputing it.
3239 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

3331 Remove unnecessary forward decls.
3333 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3335 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

3337 * dispnew.c (Fsleep_for, sit_for):
3338 * keyboard.c (kbd_buffer_get_event):
3339 * process.c (Faccept_process_output):
3340 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3341 This improves on the previous patch, which introduced a bug
3342 when time_t is unsigned and as wide as intmax_t.
3343 See <http://bugs.gnu.org/9000#51>.
3345 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3347 * dispnew.c (sit_for, Fsleep_for):

3362 Privately reported by Herbert J. Skuhra.
3363 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

3366 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3368 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3370 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in

3374 language ID in the event parameters.
3376 * w32term.c (w32_read_socket): Put the new keyboard codepage into

3406 Don't assume EMACS_TIME and struct timeval are the same type.
3408 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3410 Support higher-resolution time stamps (Bug#9000).
3411 The time stamps are only nanosecond-resolution at the C level,
3412 since that's the best that any real-world system supports now.
3413 But they are picosecond-resolution at the Lisp level, as that's
3414 easy, and leaves room for future OS improvements.
3416 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3419 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3420 Don't get current time unless it's needed.
3422 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3423 now provides it if it's absent.
3424 (start_atimer): Port to higher-res time stamps.
3425 Check for time stamp overflow. Don't get current time more
3426 often than is needed.
3428 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3429 Include systime.h, not time.h.
3430 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3432 * dired.c: Include stat-time.h.
3433 (Ffile-attributes): File times now have higher resolution.

3436 (struct image): Timestamp now has higher resolution.
3438 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3439 has at least microseconds now. All uses removed.
3440 (update_frame, update_single_window, update_window, update_frame_1)
3441 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3443 * editfns.c (time_overflow): Now extern.
3444 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3445 (float-time, Fformat_time_string, Fcurrent_time_string)
3446 (Fcurrent_time_zone): Accept and generate higher-resolution
3448 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3449 (decode_time_components, lisp_seconds_argument): New functions.
3450 (make_time): Now static.
3451 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3452 Report an error if the time is invalid, rather than having the caller
3455 * fileio.c: Include <stat-time.h>
3456 (Fcopy_file): Copy higher-resolution time stamps.
3457 Prefer to set the time stamp via a file descriptor if that works.
3458 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3459 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3460 (Fvisited_file_modtime, Fset_visited_file_modtime):
3461 Support higher-resolution time stamps.
3463 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3465 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3467 * image.c (prepare_image_for_display, clear_image_cache)
3468 (lookup_image): Port to higer-resolution time stamps.
3470 * keyboard.c (start_polling, bind_polling_period):
3471 Check for time stamp overflow.
3472 (read_char, kbd_buffer_get_event, timer_start_idle)
3473 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3474 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3475 Port to higher-resolution time stamps. Do not assume time_t is signed.
3476 (decode_timer): New function. Timers are now vectors of length 9,
3477 not 8, to accommodate the picosecond component.
3478 (timer_check_2): Use it.
3480 * nsterm.m (select_timeout, timeval_subtract): Remove.
3481 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3482 as they're a bit more accurate and handle overflow better.
3483 (ns_select): Change prototype to be compatible with pselect.
3484 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3485 * nsterm.h (ns_select): Adjust prototype.
3487 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3488 us-resolution time stamps.
3489 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3491 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3493 * lisp.h (time_overflow): New decl.
3494 (wait_reading_process_output): First arg is now intmax_t, not int,
3495 to accommodate larger waits.
3497 * process.h (struct Lisp_Process.read_output_delay):
3498 Now counts nanoseconds, not microseconds.
3499 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3501 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3502 (wait_reading_process_output):
3503 Port to ns-resolution time stamps.
3504 (Faccept_process_output, wait_reading_process_output):
3505 Check for time stamp overflow. Do not assume time_t is signed.
3506 (select_wrapper): Remove; we now use pselect.
3507 (Fprocess_attributes): Now generates ns-resolution time stamps.
3509 * sysdep.c: Include utimens.h. Don't include utime.h
3510 or worry about struct utimbuf; gnulib does that for us now.
3511 (gettimeofday): Remove; gnulib provides a substitute.
3512 (make_timeval): New function.
3513 (set_file_times): Now sets ns-resolution time stamps.
3514 New arg FD; all uses changed.
3515 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3516 (system_process_attributes):
3517 Now returns ns-resolution time stamp. All uses changed.
3518 Check for time stamp overflow.
3520 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3521 provides a substitute now.
3523 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3524 since it guarantees struct timespec.
3525 (EMACS_TIME): Now struct timespec, so that we can support
3526 ns-resolution time stamps.
3527 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3528 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3529 (EMACS_USECS): Remove.
3530 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3531 so multiply the arg by 1000 before storing it.
3532 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3534 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3535 Port to ns-resolution time stamps.
3536 (EMACS_TIME_NEG_P): Remove; replaced by....
3537 (EMACS_TIME_SIGN): New macro.
3538 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3539 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3540 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3541 (make_timeval, make_lisp_time, decode_time_components): New decls.
3542 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3543 that it mishandled time_t overflow. You can't compare by subtracting!
3544 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3545 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3547 * term.c: Include <sys/time.h>.
3548 (timeval_to_Time): New function, for proper overflow wraparound.

3553 (Fprimitive_undo): Use them when restoring time stamps.
3555 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3556 (w32_get_internal_run_time):
3557 Port to higher-resolution Emacs time stamps.
3558 (ltime): Now accepts single 64-bit integer, as that's more convenient
3561 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3563 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3564 for compatibility with pselect. Support ns-resolution time stamps.
3566 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3568 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3569 Check for time stamp overflow, and support ns-resolution time stamps.
3571 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3572 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3573 (timeval_subtract): Remove; no longer needed.
3574 (XTflash, XTring_bell, x_wait_for_event):
3575 Port to ns-resolution time stamps. Don't assume time_t is signed.
3577 2012-06-22 Chong Yidong <cyd@gnu.org>

3581 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3583 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3584 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3585 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3586 staticidx goes up to 1597 out of 1600 = 0x640.)
3588 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3590 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3591 Otherwise, the umask might be mistakenly 0 while handling input signals.
3593 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3595 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

3601 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3602 access to `contents' member of Lisp_Vector objects with AREF and ASET
3605 2012-06-19 Chong Yidong <cyd@gnu.org>
3607 * frame.c (delete_frame): When selecting a frame on a different
3608 text terminal, do not alter the terminal's top-frame.

3611 frame's selected window and its terminal's top-frame.
3612 (unwind_format_mode_line): Restore them.
3613 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3615 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3616 since tty frames can be explicitly named.
3617 (prepare_menu_bars): Likewise.
3619 * term.c (Ftty_top_frame): New function.
3621 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3623 Port byte-code-meter to modern targets.
3624 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3625 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3626 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3627 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3628 (METER_1, METER_2): Simplify.
3630 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3632 * data.c (Fdefalias): Return `symbol' (bug#11686).
3634 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3636 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3637 gets killed during executing of this function (Bug#11665).
3638 Try to always return Qt when the buffer has been actually killed.
3639 (Vkill_buffer_query_functions): In doc-string say that functions
3640 run by this hook should not change the current buffer.
3642 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3644 Fix recently-introduced process.c problems found by static checking.
3645 * process.c (write_queue_push, write_queue_pop, send_process):

3648 (send_process): Remove unused local.
3650 2012-06-17 Chong Yidong <cyd@gnu.org>

3653 frames that are not on top.
3655 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
3657 * process.c (make_process): Initialize write_queue.
3658 (write_queue_push, write_queue_pop): New functions.
3659 (send_process): Use them to maintain correct ordering of process
3662 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3664 * lisp.h (eassert): Assume C89 or later.
3665 This removes the need for CHECK.
3666 (CHECK): Remove. Its comments about always evaluating its
3667 argument were confusing, as 'eassert' typically does not evaluate
3670 * coding.c (produce_chars): Use ptrdiff_t, not int.
3672 * xterm.c (x_draw_underwave): Check for integer overflow.
3673 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
3675 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
3677 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

3858 code works fine either way, and efficiency is not a concern here,
3859 as the union type is for debugging, not for production.
3860 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3861 Use an inline function on all platforms when using the union type,
3862 since this is simpler and 'static inline' can be used portably

4006 * doprnt.c (doprnt): Truncate multibyte char correctly.
4007 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4008 would mishandle a string argument "Xc" if X was a multibyte

4010 rather than including all of X.

4063 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
4064 Convert pctcpu and pctmem to Lisp float properly.
4065 Let the compiler fold better, as 100.0/0x8000 is exact.

4084 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
4085 fields from Lisp_Object to bitfield. Adjust users accordingly.

4093 and 'double' in a couple of places.
4095 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4097 * xdisp.c (handle_stop): Detect whether we have overlay strings
4098 loaded by testing it->current.overlay_string_index to be
4099 non-negative, instead of checking whether n_overlay_strings is
4100 positive. (Bug#11587)

4110 * search.c (search_buffer): Remove calls to
4111 r_alloc_inhibit_buffer_relocation, as it is now called by
4112 maybe_unify_char, which was the cause of relocation of buffer text
4115 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4117 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4118 for the duration of call to load_charset, to avoid problems with
4119 callers of maybe_unify_char that access buffer text through C
4122 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4123 decrement the inhibition flag, instead of just setting or
4126 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>

4129 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

4133 (gray_bitmap_bits): Remove; no longer needed.

4175 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4177 Do not create empty overlays with the evaporate property (Bug#9642).
4178 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4179 Bug#9642, but explicitly check that the buffer the overlay would
4180 be moved to is live and rearrange lines to make sure that errors
4181 will not put the overlay in an inconsistent state.
4182 (Fdelete_overlay): Cosmetics.
4184 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4186 * w32term.c (my_bring_window_to_top): New function.
4187 (x_raise_frame): Use handle returned by DeferWindowPos, which
4188 could be different from the original one.

4192 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4193 by calling BringWindowToTop.
4195 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4196 (WM_EMACS_END): Increase by one.
4198 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4200 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4201 This avoids undefined behavior that might cause the eassert
4202 to not catch an out-of-range value.
4204 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4206 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4207 Update dependencies.

4216 when referring to sectname field in printf format.
4218 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4220 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4221 Only r_alloc_inhibit_buffer_relocation needed to be added;
4222 the others were already declared.
4224 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4225 before checking whether it's out of range. Put the check inside
4227 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4229 2012-05-27 Ken Brown <kbrown@cornell.edu>
4231 * callproc.c (Fcall_process): Restore a line that was accidentally
4232 commented out in the 2011-02-13 change (bug#11547).
4234 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4236 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4237 defined on ralloc.c.
4239 * buffer.c [REL_ALLOC]: Remove prototypes of
4240 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4241 they are now on lisp.h.
4243 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4245 * search.c (search_buffer): Use it to inhibit relocation of buffer
4246 text while re_search_2 is doing its job, because re_search_2 is
4247 passed C pointers to buffer text. (Bug#11519)
4249 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4252 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4253 state after an additional call to move_it_in_display_line_to, keep
4254 the values of it->max_ascent and it->max_descent found for the
4256 (pos_visible_p): Revert the comparison against bottom_y to what it
4257 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4260 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4262 Fix coding-related core dumps with gcc -ftrapv.
4263 The code was computing A - B, where A and B are pointers, and B is
4264 random garbage. This can lead to core dumps on platforms that
4265 have special pointer registers, and it also leads to core dumps on
4266 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4267 A - B only when B is initialized properly.
4268 * coding.c (coding_set_source, coding_set_destination): Return void.
4269 (coding_change_source, coding_change_destinations): New functions,
4270 with the old behaviors of coding_set_source and coding_set_destination.
4271 All callers that need an offset changed to use these new functions.
4273 2012-05-26 Glenn Morris <rgm@gnu.org>
4275 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4277 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4279 Extend mouse support on W32 text-mode console.
4280 * xdisp.c (draw_row_with_mouse_face):
4281 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4283 * w32console.c: Include window.h.
4284 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4286 (initialize_w32_display): Initialize mouse-highlight data.
4288 * w32inevt.c: Include termchar.h and window.h.
4289 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4290 moves, call note_mouse_highlight. If help_echo changed, call
4291 gen_help_event to produce help-echo message in the echo area.
4292 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4295 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4297 * lread.c (read1): Simplify slightly to avoid an overflow warning
4298 with GCC 4.7.0 on x86-64.
4300 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4302 * bidi.c (bidi_mirror_char): Revert last change: an int is
4303 definitely wide enough here.
4305 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4307 Fix integer width and related bugs (Bug#9874).

4315 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4317 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4318 (allocate_pseudovector):
4319 Use int, not EMACS_INT, where int is wide enough.
4320 (inhibit_garbage_collection, Fgarbage_collect):
4321 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4322 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4323 int might not be wide enough.
4324 (bidi_cache_search, bidi_cache_find, bidi_init_it)

4328 (bidi_level_of_next_char, bidi_move_to_visually_next):
4329 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4330 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4331 (Fkill_buffer, Fset_buffer_major_mode)

4338 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4339 (Foverlay_recenter, last_overlay_modification_hooks_used)
4340 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4341 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4342 (validate_region): Omit unnecessary test for b <= e,
4343 since that's guaranteed by the previous test.
4344 (adjust_overlays_for_delete): Avoid pos + length overflow.
4345 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4346 (report_overlay_modification):
4347 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4348 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4349 Omit pointer cast, which isn't needed anyway, and doesn't work
4350 after the EMACS_INT -> ptrdiff_t change.

4352 * buffer.h: Adjust decls to match defn changes elsewhere.

4357 not int, to avoid needless 32-bit limit on 64-bit hosts.
4358 (exec_byte_code): Use tighter memory-full test, one that checks
4359 for alloca overflow. Don't compute the address of the object just
4360 before an array, as that's not portable. Use EMACS_INT, not
4361 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4362 * callint.c (Fcall_interactively):
4363 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

4374 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4375 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4376 (casify_object): Avoid integer overflow when overallocating buffer.
4377 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4378 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4379 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4380 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4381 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4382 integers are now checked earlier. All uses replaced with XINT.
4384 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4385 For CCL_MapSingle, check that content and value are in int range.
4386 (ccl_driver, Fregister_code_conversion_map):
4387 Check that Vcode_version_map_vector is a vector.
4388 (resolve_symbol_ccl_program): Check that vector header is in range.
4389 Always copy the vector, so that we can check its contents reliably
4390 now rather than having to recheck each instruction as it's being
4391 executed. Check that vector words fit in 'int'.
4392 (ccl_get_compiled_code, Fregister_ccl_program)
4393 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4394 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4395 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4396 contents are in range.
4397 (Fccl_execute_on_string): Check that status is in range.
4398 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4399 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4400 Accept and return EMACS_INT, not int, because callers can pass values
4402 (c_string_width, strwidth, lisp_string_width, chars_in_text)

4406 (string_escape_byte8, Fget_byte):
4407 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4408 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4409 avoid mishandling large integers.
4410 * character.h: Adjust decls to match defn changes elsewhere.

4419 (Fdefine_charset_internal): Check ranges here, more carefully.
4420 Don't rely on undefined behavior with signed left shift overflow.
4421 Don't assume unsigned int fits into fixnum, or that fixnum fits
4422 into unsigned int. Don't require max_code to be a valid fixnum;
4423 that's not true for gb10830 4-byte on a 32-bit host. Allow
4424 invalid_code to be a cons, for the same reason. Require code_offset
4425 to be a character. Avoid int overflow if max_char is close
4427 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4428 this is intended anyway and avoids some undefined behavior.
4429 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4430 INDEX_TO_CODE_POINT, as that's what it expects.
4431 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4432 * charset.h (DECODE_CHAR): Return int, not unsigned;
4433 this is what was intended anyway, and it avoids undefined behavior.
4434 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4435 integer-overflow issues.
4436 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4437 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4438 where the argument is EMACS_INT, and this behavior is not intended.
4439 * chartab.c (Fmake_char_table, Fset_char_table_range)
4440 (uniprop_get_decoder, uniprop_get_encoder):
4441 Don't assume fixnum fits in int.
4442 * cmds.c (move_point): New function, that does the gist of
4443 Fforward_char and Fbackward_char, but does so while checking
4444 for integer overflow more accurately.
4445 (Fforward_char, Fbackward_char): Use it.
4446 (Fforward_line, Fend_of_line, internal_self_insert)
4447 (internal_self_insert):
4448 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4449 Fix a FIXME, by checking for integer overflow when calculating
4450 target_clm and actual_clm.

4485 Don't access memory outside of the args array.
4486 (Fdefine_coding_system_internal): Check for charset-id overflow.

5250 iterator, by calling iterate_out_of_display_property.

5252 testing that it->string is a Lisp string.
5253 (get_next_display_element): When the current object is exhausted,

5266 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5267 and right-margin display specs even if the spec is invalid or we
5268 are on a TTY, and thus unable to display on the fringes.
5269 That's because the text with the property will not be displayed anyway,
5270 so we need to signal to the caller that this is a "replacing"
5271 display spec. This fixes display when the spec is invalid or we
5274 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5276 * unexaix.c (make_hdr): Fix typo in prototype.

5309 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5311 * xgselect.c (xg_select): Put maxfds+1 into a var.
5312 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5314 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5316 2012-05-10 Dave Abrahams <dave@boostpro.com>
5318 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5319 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5321 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5323 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5324 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5325 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5326 Initialize xd_registered_buses.
5328 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5330 Untag more efficiently if USE_LSB_TAG.
5331 This is based on a proposal by YAMAMOTO Mitsuharu in
5332 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5333 For an admittedly artificial (nth 8000 longlist) benchmark on
5334 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5335 Emacs's overall text size by 1%.
5336 * lisp.h (XUNTAG): New macro.
5337 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5338 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5339 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5340 * eval.c (Fautoload):
5341 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5342 * frame.h (XFRAME): Use XUNTAG.
5344 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5345 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5346 Remove unportable assumptions about print widths of types like
5348 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5349 intptr_t when converting between pointer and integer, to avoid GCC
5350 warnings about wrong width.
5352 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5354 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5355 stack for each reader_thread, instead of defaulting to 8MB
5356 determined by the linker. This avoids failures in creating
5357 subprocesses on Windows 7, see the discussion in this thread:
5358 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5360 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5362 Fix up display of the *Minibuf-0* buffer in the mini window.
5363 * keyboard.c (read_char): Don't clear the echo area if there's no
5365 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5366 contents of *Minibuf-0*) if there's no message displayed in its stead.
5368 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5370 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5373 2012-05-06 Chong Yidong <cyd@gnu.org>
5375 * lisp.mk (lisp): Update.
5377 2012-05-05 Jim Meyering <meyering@redhat.com>
5379 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5381 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5383 * data.c (PUT_ERROR): New macro.
5384 (syms_of_data): Use it. Add new error type `user-error'.
5385 * undo.c (user_error): New function.
5386 (Fprimitive_undo): Use it.
5387 * print.c (print_error_message): Adjust print style for `user-error'.
5388 * keyboard.c (user_error): New function.
5389 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5391 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5393 Do not limit current-time-string to years 1000..9999.
5394 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5395 (Fcurrent_time_string): Support any year that is supported by the
5396 underlying localtime representation. Don't use asctime, as it
5397 has undefined behavior for years outside the range -999..9999.
5399 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5401 Fix race conditions involving setenv, gmtime, localtime, asctime.
5402 Without this fix, interrupts could mess up code that uses these
5403 nonreentrant functions, since setting TZ invalidates existing
5404 tm_zone or tzname values, and since most of these functions return
5405 pointers to static storage.
5406 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5407 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5408 Grow the critical sections to include not just invoking
5409 localtime/gmtime, but also accessing these functions' results
5410 including their tm_zone values if any, and any related TZ setting.
5411 (format_time_string): Last arg is now struct tm *, not struct tm **,
5412 so that the struct tm is saved in the critical section.
5413 All callers changed. Simplify allocation of initial buffer, partly
5414 motivated by the fact that memory allocation needs to be outside
5415 the critical section.
5417 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5419 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5420 with RESET_INTERVAL.
5422 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5423 Remove duplicated buffer name initialization.
5425 2012-05-02 Jim Meyering <jim@meyering.net>
5427 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5429 * xfns.c (x_window): Use xstrdup (Bug#11375).
5431 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5433 * xdisp.c (pos_visible_p): If already at a newline from the
5434 display string before the 'while' loop, don't walk back the glyphs
5435 from it3.glyph_row. Solves assertion violation when the display
5436 string begins with a newline (egg.el). (Bug#11367)
5438 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5440 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5443 2012-05-01 Glenn Morris <rgm@gnu.org>
5445 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5446 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5447 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5448 All were removed before 23.1.
5450 * dispnew.c: Remove HAVE_LIBNCURSES test;
5451 it is always true on relevant platforms.
5453 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5454 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5456 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5458 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5460 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5461 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5464 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5466 Do not avoid creating empty evaporating overlays (Bug#9642).
5467 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5468 That is, do not delete an evaporating overlay if it becomes
5469 empty after its bounds are adjusted to fit within its buffer.
5470 This fix caused other problems, and I'm reverting it until we get
5471 to the bottom of them.
5473 2012-04-27 Chong Yidong <cyd@gnu.org>
5475 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5477 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5479 * xdisp.c (pos_visible_p): If the window start position is beyond
5480 ZV, start the display from buffer beginning. Prevents assertion
5481 violation in init_iterator when the minibuffer window is scrolled
5484 * window.c (window_scroll_pixel_based): Likewise.
5486 2012-04-27 Chong Yidong <cyd@gnu.org>
5488 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5490 2012-04-27 Glenn Morris <rgm@gnu.org>
5492 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5493 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5495 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5497 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5498 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5500 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5502 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5503 display element, check also the underlying string or buffer
5504 character. (Bug#11341)
5506 * w32menu.c: Include w32heap.h.
5507 (add_menu_item): If the call to AppendMenuW (via
5508 unicode_append_menu) fails, disable Unicode menus only if we are
5509 running on Windows 9X/Me.
5511 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5513 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5514 (xgetint): Add missing shift for LSB tags.
5516 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5518 * keyboard.c (read_char): Don't wipe echo area for select window
5519 events: These might get delayed via `mouse-autoselect-window'
5522 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5524 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5525 manipulation of :loaded-from data.
5527 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5529 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5530 now a cons (bug#11311).
5532 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5534 Do not create empty overlays with the evaporate property (Bug#9642).
5535 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5536 if it becomes empty after its bounds are adjusted to fit within
5537 its buffer. Without this fix, in a nonempty buffer (let ((o
5538 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5539 yields an empty overlay that has the evaporate property, which is
5540 not supposed to happen.
5542 Fix minor GTK3 problems found by static checking.
5543 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5544 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5545 (struct _EmacsFixedClass, emacs_fixed_get_type):

5555 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5557 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5558 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5560 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5562 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5563 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5564 (__malloc_size_t, __malloc_ptrdiff_t):
5565 Remove. All uses removed, replaced by the definiens if needed,
5566 since we can assume C89 or better now.
5567 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5568 (protect_malloc_state, align, get_contiguous_space)
5569 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

5575 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5576 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5577 Define using prototypes, not old style.
5578 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5579 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5580 (align): Don't assume that signed integer overflow wraps around.
5581 Omit unused local var.
5582 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5583 (_free_internal_nolock, memalign, mallochook, reallochook):

5642 * alloc.c: Handle unusual debugging option combinations.
5643 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,

5657 * sysdep.c [__FreeBSD__]: Minor cleanups.
5658 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5659 Use Emacs indenting style more consistently. Avoid some casts.

5701 farther than the first row after the header line, if any.
5702 Don't consider the header-line row as "partially visible", even if
5703 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

5758 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
5759 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
5760 [REL_ALLOC]: ... to here, to check interface.
5761 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5762 Remove decls. This fixes an "It stinks!".
5764 * alloc.c (which_symbols): Fix alignment issue / type clash.
5766 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5768 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
5769 (struct Lisp_Misc_Any): Likewise.
5770 (struct Lisp_Free): Likewise.
5771 * alloc.c (union aligned_Lisp_Symbol): Define.
5772 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
5773 aligned_Lisp_Symbol instead of struct Lisp_Symbol.
5774 (union aligned_Lisp_Misc): Define.
5775 (MARKER_BLOCK_SIZE, struct marker_block): Use union
5776 aligned_Lisp_Misc instead of union Lisp_Misc.
5777 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
5779 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5781 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5782 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5783 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5784 * s/netbsd.h, s/sol2-6.h:
5785 Remove definition of GC_MARK_STACK, since the default now works.
5786 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5787 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5788 no longer the default.
5789 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5791 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5793 * lread.c (lisp_file_lexically_bound_p):
5794 Fix hang at ";-*-\n" (bug#11238).

5801 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5803 * nsterm.m (constrainFrameRect): Always constrain when there is only
5804 one screen (Bug#10962).
5806 2012-04-13 Ken Brown <kbrown@cornell.edu>
5808 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

5814 2012-04-11 Daniel Colascione <dancol@dancol.org>
5816 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5817 against is gone. It's better to use vfork now so that when Cygwin
5818 gains a new, working vfork, we use it automatically (bug#10398).
5820 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5822 * window.c (save_window_save): Obey window-point-insertion-type.

5832 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
5834 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
5835 (force_quit_count): New var.
5836 (handle_interrupt): Use it.
5838 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5840 * w32.c (w32_delayed_load): Record the full path of the library
5841 being loaded (bug#10424).
5843 2012-04-09 Glenn Morris <rgm@gnu.org>
5845 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5846 not just in the obarray, before snarfing them. (Bug#11036)
5848 * Makefile.in ($(leimdir)/leim-list.el):
5849 Pass EMACS rather than BUILT_EMACS.
5851 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5853 * process.c (make_process):
5854 * process.h: Add integer `gnutls_handshakes_tried' member to
5857 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5858 Add convenience `GNUTLS_LOG2i' macro.
5860 * gnutls.c (gnutls_log_function2i): Convenience log function.
5861 (emacs_gnutls_read): Use new log functions,
5862 `gnutls_handshakes_tried' process member, and
5863 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5864 attempts per process (connection).
5866 2012-04-09 Chong Yidong <cyd@gnu.org>
5868 * eval.c (Fuser_variable_p, user_variable_p_eh)
5869 (lisp_indirect_variable): Functions deleted.
5870 (Fdefvar): Caller changed.
5872 * callint.c (Finteractive, Fcall_interactively):
5873 * minibuf.c (Fread_variable): Callers changed.
5875 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5877 * xdisp.c (set_cursor_from_row): If the display string appears in
5878 the buffer at position that is closer to point than the position
5879 after the display string, display the cursor on the first glyph of
5880 the display string. Fixes cursor display when a 'display' text
5881 property immediately follows invisible text. (Bug#11094)
5883 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5885 composite.c: use 'double' consistently
5886 * composite.c (get_composition_id): Use 'double' consistently
5887 instead of converting 'float' to 'double' and vice versa; this is
5888 easier to understand and avoids a GCC warning.
5890 2012-04-09 Glenn Morris <rgm@gnu.org>
5892 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5893 preparation for dumping it with emacs. (Bug#4789)
5894 (leimdir): New variable.
5895 ($(leimdir)/leim-list.el): New rule.
5896 (emacs$(EXEEXT)): Depend on leim-list.el.

5902 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
5904 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5907 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
5909 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5910 Remove unused local variable.
5912 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5914 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5915 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5916 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5917 objects, as mark_maybe_pointer will catch them otherwise.
5918 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5919 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5921 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5923 Fix typo that broke non-Windows builds.
5924 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5926 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5928 Support building on MS-Windows with libxml2.
5930 * makefile.w32-in (OBJ2): Add xml.$(O).
5931 (GLOBAL_SOURCES): Add xml.c.
5932 ($(BLD)/xml.$(O)): New dependency list.
5934 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5935 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5936 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5937 [!WINDOWSNT]: New macros.
5938 (init_libxml2_functions, libxml2_loaded_p): New functions.
5939 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5940 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5941 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5942 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5944 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5945 Call init_libxml2_functions before calling libxml2 functions.
5946 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5948 * emacs.c: Don't include libxml/parser.h.
5949 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5950 xmlCleanupParser directly.
5952 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5954 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5956 * indent.c (Fvertical_motion): If there is a display string at
5957 point, use it.vpos to compute how many lines to backtrack after
5958 move_it_to point. (Bug#11133)
5960 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5962 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5963 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5964 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5965 macros related to unification of CJK characters. For the details,
5966 see the discussion following the message here:
5967 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5969 2012-04-04 Chong Yidong <cyd@gnu.org>
5971 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5973 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5975 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5976 instead of alloca. (Bug#11138)
5978 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5980 * w32menu.c (is_simple_dialog): Properly check lisp types.
5983 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5985 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5986 position we get to after a call to move_it_to fails the
5987 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5988 only if we wind up in a string from display property. (Bug#11063)
5990 * window.c (Fdelete_other_windows_internal): Invalidate the row
5991 and column information about mouse highlight, so that redisplay
5992 restores it after reallocating the glyph matrices. (Bug#7464)
5994 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5995 string comes from a `display' text property, use the buffer
5996 position of that property as if we actually saw that position in
5998 (move_it_by_lines): Remove the assertion that
5999 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6000 violated when there's a before-string at the beginning of a line.
6003 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6005 * xdisp.c (append_space_for_newline): If the default face was
6006 remapped, use the remapped face for the appended newline.
6007 (extend_face_to_end_of_line): Use the remapped default face for
6008 extending the face to the end of the line.
6009 (display_line): Call extend_face_to_end_of_line when the default
6010 face was remapped. (Bug#11068)
6012 2012-03-29 Eli Zaretskii <eliz@gnu.org>
6014 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
6016 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
6018 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
6020 2012-03-27 Glenn Morris <rgm@gnu.org>
6022 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
6025 2012-03-26 Kenichi Handa <handa@m17n.org>
6027 * dispextern.h (struct glyph): Fix previous change. Change the
6028 bit length of glyphless.ch to 25 (Bug#11082).
6030 2012-03-26 Chong Yidong <cyd@gnu.org>
6032 * keyboard.c (Vselection_inhibit_update_commands): New variable.
6033 (command_loop_1): Use it; inhibit selection update for
6034 handle-select-window too (Bug#8996).
6036 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
6038 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
6040 2012-03-25 Kenichi Handa <handa@m17n.org>
6042 * dispextern.h (struct glyph): Change the bit length of
6043 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6045 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6047 * s/ms-w32.h (tzname): Include time.h before redirecting to
6048 _tzname. Fixes the MSVC build. (Bug#9960)
6050 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
6052 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6055 * xterm.c (XTread_socket): Only modify handling_signal if
6056 !SYNC_INPUT. (Bug#11080)
6058 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6060 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6061 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6062 when fetching a multibyte character consumes more bytes than
6063 CHAR_BYTES returns, due to unification of CJK characters in
6064 string_char. (Bug#11073)
6066 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6068 * process.c (wait_reading_process_output): Handle pty disconnect
6069 by refraining from sending oneself a SIGCHLD (bug#10933).
6071 2012-03-22 Chong Yidong <cyd@gnu.org>
6073 * dispextern.h (struct it): New member string_from_prefix_prop_p.
6075 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
6076 Mark string as coming from a prefix property.
6077 (handle_face_prop): Use default face for prefix strings (Bug#4281).
6078 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
6080 2012-03-21 Chong Yidong <cyd@gnu.org>
6082 * xfaces.c (Vface_remapping_alist): Doc fix.
6084 2012-03-20 Eli Zaretskii <eliz@gnu.org>
6086 * w32proc.c (Fw32_set_console_codepage)
6087 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
6090 2012-03-20 Chong Yidong <cyd@gnu.org>
6092 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
6093 to reflect default non-nil value of redisplay-dont-pause.
6095 2012-03-19 Kenichi Handa <handa@m17n.org>
6097 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
6098 it fit in a valid range (Bug#11003).
6100 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6102 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6103 that is not from display property, accept the row as a "cursor
6104 row" if one of the string's character has a non-nil `cursor'
6105 property. Fixes cursor positioning when there are newlines in
6106 overlay strings, e.g. in icomplete.el. (Bug#11035)
6108 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6110 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
6112 2012-03-12 Chong Yidong <cyd@gnu.org>
6114 * eval.c (inhibit_lisp_code): Rename from
6115 inhibit_window_configuration_change_hook; move from window.c.
6117 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6118 * window.c (run_window_configuration_change_hook)
6119 (syms_of_window): Callers changed.
6121 2012-03-11 Chong Yidong <cyd@gnu.org>
6123 * keymap.c (Fkey_description): Doc fix (Bug#9700).
6125 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
6127 2012-03-10 Chong Yidong <cyd@gnu.org>
6129 * frame.c (other_visible_frames): Don't assume the selected frame
6130 is visible (Bug#10955).
6132 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
6134 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6136 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6138 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6139 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6142 2012-03-03 Glenn Morris <rgm@gnu.org>
6144 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6146 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6148 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6149 position past the first glyph_row that ends at ZV. (Bug#10902)
6150 (redisplay_window, next_element_from_string): Fix typos in
6152 (redisplay_window): Pass to move_it_vertically the margin in
6153 pixels, not in screen lines.
6155 2012-03-02 Glenn Morris <rgm@gnu.org>
6157 * buffer.c (buffer-list-update-hook): Doc fix.
6159 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6161 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6162 push_it before setting up the iterator for the first overlay
6163 string, even if we have an empty string loaded.
6164 (next_overlay_string): If there's an empty string on the iterator
6165 stack, pop the stack. (Bug#10903)
6167 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6169 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6170 Suggested by Stefan Monnier in
6171 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6172 * alloc.c (widen_to_Lisp_Object): New static function.
6173 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6174 and widening them to Lisp_Objects. This would work even if
6175 USE_LSB_TAG is defined and wide integers are used, which might
6176 happen in a future version of Emacs.
6178 2012-02-25 Chong Yidong <cyd@gnu.org>
6180 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6183 * xselect.c (Fx_selection_exists_p): Doc fix.
6184 (x_clipboard_manager_save_all): Print an informative message
6185 before saving to clipboard manager.
6187 2012-02-24 Chong Yidong <cyd@gnu.org>
6189 * keyboard.c (process_special_events): Handle all X selection
6190 requests in kbd_buffer, not just the next one (Bug#8869).
6192 2012-02-23 Chong Yidong <cyd@gnu.org>
6194 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
6195 call when setting menu-bar-lines and tool-bar-lines parameters.
6196 (unwind_create_frame_1): New helper function.
6198 * window.c (inhibit_window_configuration_change_hook): New var.
6199 (run_window_configuration_change_hook): Obey it.
6200 (syms_of_window): Initialize it.
6202 2012-02-22 Chong Yidong <cyd@gnu.org>
6204 * xterm.c (x_draw_image_relief): Add missing type check for
6205 Vtool_bar_button_margin (Bug#10743).
6207 2012-02-21 Chong Yidong <cyd@gnu.org>
6209 * fileio.c (Vfile_name_handler_alist): Doc fix.
6211 * buffer.c (Fget_file_buffer): Protect against invalid file
6212 handler return value.
6214 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
6216 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
6217 when computing $valmask.
6219 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6220 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6221 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6222 It's useless in that case, and it can cause problems on hosts
6223 that allocate halves of EMACS_INT values separately.
6224 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6225 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6226 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6227 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6228 it avoids undefined behavior on hosts where shifting right by more
6229 than the word width has undefined behavior.
6231 2012-02-19 Chong Yidong <cyd@gnu.org>
6233 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
6234 (Funhandled_file_name_directory, Ffile_name_as_directory)
6235 (Fdirectory_file_name, Fexpand_file_name)
6236 (Fsubstitute_in_file_name): Protect against invalid file handler

7017 to 4 (xorl, subq, cmpq, setbe).
7018 * alloc.c (pure): Always extern now, since that's the

7031 behave as if the cursor position were at the window margin.
7033 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7034 and the cursor position is out of bounds, behave as if the cursor

7065 * dispnew.c (verify_row_hash): Call row_hash for computing the
7066 hash code of a row, instead of duplicating code from xdisp.c.
7068 * dispextern.h (row_hash): Add prototype.
7070 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
7072 * frame.c (delete_frame): Don't delete the terminal when the last

7227 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
7228 This is also needed for porting to any host where GC_MARK_STACK is
7229 not GC_MAKE_GCPROS_NOOPS.
7230 (which_symbols): Use it.
7232 2011-11-07 Kenichi Handa <handa@m17n.org>
7234 * coding.c (coding_set_destination): Check coding->src_pos only
7235 when coding->src_object is a buffer (bug#9910).

7243 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7245 * xmenu.c (cleanup_widget_value_tree): New function.
7246 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
7247 calling free_menubar_widget_value_tree directly (Bug#9830).
7249 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
7251 Fix some portability problems with 'inline'.
7252 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
7253 (window_box_width, window_box_left, window_box_left_offset)
7254 (window_box_right, window_box_right_offset): Declare extern.
7255 Otherwise, these inline functions do not conform to C99 and
7256 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7257 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7258 * intervals.c (adjust_intervals_for_insertion)
7259 (adjust_intervals_for_deletion): Now extern, because otherwise the
7260 extern inline functions 'offset_intervals' couldn't refer to it.
7261 (static_offset_intervals): Remove.
7262 (offset_intervals): Rewrite using the old contents of
7263 static_offset_intervals. The old version didn't conform to C99
7264 because an extern inline function contained a reference to an
7265 identifier with static linkage.
7267 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
7269 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

7287 (Fwindow_vscroll): Doc fix.
7288 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
7289 argument, since it makes no sense to pass a live window and for
7290 consistency with window-child.

7320 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
7321 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
7322 Move terminal->reference_count++ just before making the frame official
7325 * nsterm.m (x_free_frame_resources): New function.
7326 (x_destroy_window): Move code to x_free_frame_resources.

7371 * xdisp.c (note_mouse_highlight): If either of
7372 previous/next-single-property-change returns nil, treat that as
7373 the beginning or the end of the buffer. (Bug#9955)

7401 Rename cover_string to disp_string.
7403 2011-11-01 Martin Rudalics <rudalics@gmx.at>

7434 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
7436 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
7437 so that this new function doesn't get optimized away by a
7438 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
7440 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>

7498 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
7500 (w32font_open_internal, compute_metrics):
7501 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7502 instead of calling the "wide" APIs directly.
7504 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

7517 * process.c (make_process): Set gnutls_state to NULL.
7519 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
7520 non-NULL, regardless of GNUTLS_INITSTAGE.
7521 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7522 an error. Set process slots as soon as we allocate them.

7568 current character, check also for next_en_type being WEAK_EN.
7569 (bidi_resolve_weak): Don't enter the expensive loop if the current
7570 position is before next_en_pos. Record the bidi type of the first
7571 non-ET, non-BN character we find, in addition to its position.
7572 (bidi_level_of_next_char): Invalidate next_en_type when
7573 next_en_pos is over-stepped.
7575 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7577 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7578 * editfns.c: Rewrite current-time-zone so that it invokes
7579 the equivalent of (format-time-string "%Z") to get the time zone name.
7580 This fixes a bug when the time zone name contains characters that
7581 need converting from the system time locale to Emacs internal format.
7582 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7583 that patch fixed format-time-string to do the conversion, but
7584 I forgot to fix current-time-zone.
7585 (format_time_string): New function, containing most of
7586 what Fformat_time_string used to contain.
7587 (Fformat_time_string): Rewrite in terms of format_time_string.
7588 This doesn't change this function's behavior.
7589 (current-time-zone): Rewrite to use format_time_string.
7590 This fixes the bug reported by Michael Schierl in
7591 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7592 Jason Rumney's 2007-06-07 change worked around this bug, but
7594 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7596 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7598 * xdisp.c (start_display): If the character at POS is displayed
7599 via a display vector, reset IT->current.dpvec_index to zero.
7600 (try_window_reusing_current_matrix): If a line ends in a display
7601 vector or the next line starts in a display vector, continue
7602 redrawing the window even though the character position of
7603 start_row was reached.
7606 2011-10-18 Chong Yidong <cyd@gnu.org>
7608 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7609 with nobreak-char-display too.
7611 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7613 Fix part 3 of bug#9771.
7614 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7615 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7616 non-neutral characters if the current character is a paragraph
7617 separator (a.k.a. Newline). This avoids running the same
7618 expensive loop twice, once when we consume the preceding newline
7619 and the other time when the line actually needs to be displayed.
7620 Avoid the loop when we see neutrals on the base embedding level
7621 following a character whose directionality is the same as the
7622 paragraph's. This avoids running the expensive loop when a line
7623 ends in a long sequence of neutrals, like control characters.
7624 Add assertion against STRONG_AL type. Slightly rearrange code
7625 that determines the type of a neutral given the first non-neutral
7627 (bidi_level_of_next_char): Set next_en_pos to zero when
7628 invalidating its info.
7630 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7632 * xdisp.c (push_display_prop): Determine whether to record string
7633 or buffer position by IT->string, not by IT->method. Allow
7634 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7635 (move_it_vertically_backward): Don't look for character position
7636 immediately after the newline when in a continuation line.
7639 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7641 * window.c (coordinates_in_window): Rewrite and delabelize
7642 vertical border check. (Bug#5357) (Bug#9618)
7644 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7646 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7647 errors in XSetWindowBorder (bug#9310).

7651 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7652 avoid crash when xmalloc overrun checking is enabled.
7654 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7656 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7657 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7658 cursor motion with <left> and <right> arrow keys.
7660 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7661 some callers set that themselves.
7663 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7665 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7666 display string and the previous row comes from the same string and
7667 is empty. (Bug#9739) (Bug#9738)
7669 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7671 * doc.c (get_doc_string): Encode file name (bug#9735).
7673 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7675 * bidi.c (bidi_level_of_next_char):
7676 * xdisp.c (get_visually_first_element): Remove old incorrect
7677 comments regarding the Unicode Line Separator character.
7679 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7681 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

7687 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7689 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7690 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7692 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7693 Some packages use them to denote characters with modifiers.

7697 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7698 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7699 matching a pp-number. Rename parameter var to var1.
7701 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7703 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7705 2011-10-08 Glenn Morris <rgm@gnu.org>
7707 * callint.c (Fcall_interactively): Give a more explicit error for the
7708 'c' case with a non-character input. (Bug#8479)
7710 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7712 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7714 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7715 lines that are hscrolled on the left.
7717 * dispnew.c (buffer_posn_from_coords): Account for a possible
7718 presence of header-line. (Bug#4426)
7720 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7722 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7723 Don't advertise functionality which we discourage or doesn't work.
7725 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7727 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7728 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7729 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7730 this makes Emacs dump core during garbage collection on rare
7731 occasions. sizeof is obviously inferior to offsetof here, so
7732 stick with offsetof.
7733 (GC_POINTER_ALIGNMENT): New macro.
7734 (mark_memory): Omit 3rd (offset) arg; caller changed.
7735 Don't assume EMACS_INT alignment is the same as pointer alignment.
7737 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7739 * keyboard.c (read_key_sequence_remapped): New var.
7740 (read_key_sequence): Compute remapping in the right buffer.
7741 (command_loop_1): Use read_key_sequence's remapping directly.
7743 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7745 * dired.c (file_name_completion): Don't expand file name.
7746 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7747 before checking file name handler.
7749 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7750 they've been requested explicitly (bug#9591).
7752 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7754 * keymap.c (Fsingle_key_description): Use make_specified_string
7755 instead of build_string to build string from push_key_description.
7758 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7760 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7761 This fixes a Y2038 bug on 64-bit hosts.
7762 * buffer.c (reset_buffer):
7763 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7764 (Fclear_buffer_auto_save_failure):
7765 Use 0, not -1, to represent an unset failure time, since time_t
7766 might not be signed.
7768 Remove dependency on glibc malloc internals.
7769 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7770 Move back here from lisp.h, but with their new implementations.
7771 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7772 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7773 * charset.c (charset_table_init): New static var.
7774 (syms_of_charset): Use it instead of xmalloc. This removes a
7775 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7776 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7777 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7778 Move back to alloc.c.
7779 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7780 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7782 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7784 * nsterm.m (windowDidResize): Call x_set_window_size only when
7785 ns_in_resize is true. Otherwise set pixelwidth/height and
7786 call change_frame_size (Bug#9628).
7788 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7790 Port --enable-checking=all to Fedora 14 x86-64.
7791 * charset.c (syms_of_charset): Also account for glibc malloc's
7792 internal overhead when calculating the initial malloc maximum.
7794 Port --enable-checking=all to Fedora 14 x86.
7795 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7797 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7798 (overrun_check_realloc, overrun_check_free):
7799 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7800 That way, xmalloc returns a properly-aligned pointer even if
7801 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7802 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7803 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7804 into account when calculating the initial malloc maximum.
7805 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7806 Move here from alloc.c, so that charset.c can use it too.
7807 Properly align; the old code wasn't right for common 32-bit hosts
7808 when configured with --enable-checking=all.
7809 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7810 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7812 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7814 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7817 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7819 * xdisp.c (compute_display_string_end): If there's no display
7820 string at CHARPOS, return -1.
7822 * bidi.c (bidi_fetch_char): When compute_display_string_end
7823 returns a negative value, treat the character as a normal
7824 character not covered by a display string. (Bug#9624)
7826 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7828 * lread.c (Fread_from_string): Fix typo in docstring.
7830 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7832 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7833 newline, reseat the iterator instead of bidi-iterating there one
7834 character at a time. (Bug#9610)
7835 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7836 TO_CHARPOS if the bidi iterator is at base embedding level.
7838 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7840 * lread.c (readevalloop): Use correct code for NBSP.
7841 (read1): Likewise. (Bug#9608)
7843 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7845 * dbusbind.c (Fdbus_register_signal): When service is not
7846 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7848 2011-09-25 Glenn Morris <rgm@gnu.org>
7850 * buffer.c (truncate-lines): Doc fix.
7852 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7854 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7855 (Fset_window_next_buffers): Doc fix.
7857 2011-09-24 Glenn Morris <rgm@gnu.org>
7859 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7861 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7863 Fix minor problems found by static checking.
7864 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7865 * indent.c (Fvertical_motion): Fix == vs = typo.
7867 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7869 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7870 Default value is now t. Doc fix.
7872 * indent.c (Fvertical_motion): Compute and apply the overshoot
7873 logic when moving up, not only when moving down. Fix the
7874 confusing name and values of the it_overshoot_expected variable;
7875 logic changes accordingly. (Bug#9254) (Bug#9549)
7877 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7878 CHARPOS is covered by a display string which includes newlines.
7879 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7880 is covered by a display string with embedded newlines.
7882 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7884 * dbusbind.c (Fdbus_register_signal): Add match rule to
7885 Vdbus_registered_objects_table. (Bug#9581)
7886 (Fdbus_register_method, Vdbus_registered_objects_table):
7889 2011-09-24 Jim Meyering <meyering@redhat.com>
7891 do not ignore write error for any output size
7892 The previous change was incomplete.
7893 While it makes emacs --batch detect the vast majority of stdout
7894 write failures, errors were still ignored whenever the output size is
7895 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7896 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7897 && echo FAIL: ignored write error
7898 FAIL: ignored write error
7899 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7900 && echo FAIL: ignored write error
7901 FAIL: ignored write error
7902 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7904 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7906 * emacs.c (Fkill_emacs): In noninteractive mode exit
7907 non-successfully if a write error occurred on stdout. (Bug#9574)
7909 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7911 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7914 * dispextern.h (struct it): Update the comment documenting what
7917 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7919 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7920 a display string, extend search for cursor position to end of row.
7921 (find_row_edges): If the row ends in a newline from a display
7922 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7923 Handle the case of a display string with multiple newlines.
7924 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7925 non-empty line. Fixes confusing cursor motion with arrow keys at
7926 the beginning of a line that starts with whitespace.
7928 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7930 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7933 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7935 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7938 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7940 * xdisp.c (display_line): Record maximum and minimum buffer
7941 positions even if no glyphs were produced (e.g., by a zero-width
7942 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7943 buffer positions that will be removed from the glyph row because
7945 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7946 column is beyond frame width: don't subtract 1 "pixel" when
7947 computing width of the stretch.
7948 (reseat_at_next_visible_line_start): Undo the change made on
7949 2011-09-17 that saved paragraph information and restored it after
7950 the call to `reseat'. (Bug#9545)
7952 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7954 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7955 and turn window cursor on if cleared (Bug#9415).
7957 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7959 * search.c (boyer_moore): Take unibyte characters from pattern
7960 literally. (Bug#9458)
7962 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7964 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7966 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7968 Fix minor problem found by static checking.
7969 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7970 initialized, to pacify gcc -Wuninitialized.
7972 * fileio.c: Report proper errno when syscall falls.
7973 (Finsert_file_contents): Save and restore errno,
7974 so that report_file_error outputs the correct diagnostic.
7975 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7977 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7979 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7981 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7983 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7984 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7986 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7988 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7989 about the current paragraph and restore it after the call to reseat.
7991 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7992 (bidi_find_paragraph_start): Search back for paragraph beginning
7993 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7994 (bidi_move_to_visually_next): Only trigger paragraph-related
7995 computations when the last character is a newline or at EOB, not
7996 just any NEUTRAL_B. (Bug#9470)
7998 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7999 truncated lines if point is covered by a display string. (Bug#9524)
8001 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
8003 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8004 (cons_to_x_long): New function.
8005 (lisp_data_to_selection_data): Use it. Correct the test for
8006 short-versus-long data; it was negated. Break out of vector
8007 loop, for efficiency, when a long datum is discovered.
8009 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8011 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8013 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8015 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
8016 GCC PR/17406) by declaring this function with external scope.
8018 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8020 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
8021 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
8023 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
8025 * editfns.c (Fformat): Correctly handle text properties on "%%".
8027 2011-09-15 Eli Zaretskii <eliz@gnu.org>
8029 * xterm.c (x_draw_composite_glyph_string_foreground):
8030 * w32term.c (x_draw_composite_glyph_string_foreground):
8031 * term.c (encode_terminal_code):
8032 * composite.c (composition_update_it, get_composition_id):
8033 * xdisp.c (get_next_display_element)

8035 of TAB characters in a composition.
8037 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8039 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8040 This occurs when processing a multibyte format.
8041 Problem reported by Wolfgang Jenker.
8043 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8045 * xdisp.c (try_cursor_movement): Only check for exact match if
8046 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8048 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8050 Remove unused external symbols.
8051 * dispextern.h (calc_pixel_width_or_height): Remove decl.
8052 * xdisp.c (calc_pixel_width_or_height): Now static.
8053 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
8054 * indent.c (check_display_width):
8055 * w32term.c: Fix comment to match code.
8056 * xterm.c, xterm.h (x_catching_errors): Remove.
8058 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8060 * xselect.c: Use signed conversions more consistently (Bug#9498).
8061 (selection_data_to_lisp_data): Assume incoming selection data are
8062 signed integers, not unsigned. This is to be consistent with
8063 outgoing selection data, which was modified to use signed integers
8064 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8065 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8066 expects long, not unsigned long.
8068 2011-09-14 Eli Zaretskii <eliz@gnu.org>
8070 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
8071 computation of loop end. Reported by Johan Bockgård
8074 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
8076 * frame.c (Fother_visible_frames_p): Function deleted.
8078 2011-09-12 Eli Zaretskii <eliz@gnu.org>
8080 * indent.c (compute_motion): Process display vector front to back
8081 rather than the other way around. (Bug#2496)
8083 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
8085 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
8087 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
8089 * minibuf.c (Fread_from_minibuffer): Doc fix.
8091 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8093 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8094 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8096 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8098 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8099 value for non-existent files.
8101 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8103 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8104 set its "size" to -1. This will set the modtime_size field of
8105 the corresponding buffer to -1, which is what
8106 verify-visited-file-modtime expects for files that do not exist.
8109 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8111 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8113 * lisp.h: ... from here. push_key_description is no longer
8114 defined in keyboard.c, so its declaration should not be in
8115 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8116 logically belongs with push_key_description.
8118 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8120 * buffer.h: Include <sys/types.h> instead of <time.h>.
8121 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8122 Problem reported by Herbert J. Skuhra.
8124 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8126 * xml.c (parse_region): Make the parsing work for
8127 non-comment-starting XML files again (bug#9144).
8129 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8131 * image.c (gif_load): Fix calculation of bottom and right corner.
8134 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8136 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8137 redisplay in small windows.
8139 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8141 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8143 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8145 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8146 Operate on live windows only.
8148 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8150 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8152 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8154 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8155 only under bidi iteration.
8157 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8159 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8161 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8163 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8164 Without this fix, the command to link temacs failed due to an
8165 undefined symbol __builtin_isnan. This is because
8166 /usr/include/iso/math_c99.h #defines isnan(x) to
8167 __builtin_isnan(x), but the bundled gcc, which identifies itself
8168 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8170 * floatfns.c (isnan): #undef, and then #define to a clone of
8172 (Fisnan): Always define, since it's always available now.
8173 (syms_of_floatfns): Always define isnan at the Lisp level.
8175 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8177 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8179 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8181 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8182 The previous code assumed that file offsets (off_t values) fit in
8183 EMACS_INT variables, which is not true on typical 32-bit hosts.
8184 The code messed up by falsely reporting buffer overflow in cases
8185 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8186 when "big" contains more than 2**29 bytes, even though this
8187 inserts just one byte and does not overflow the buffer.
8188 (Finsert_file_contents): Store file offsets as off_t
8189 values, not as EMACS_INT values. Check for overflow when
8190 converting between EMACS_INT and off_t. When checking for
8191 buffer overflow or for overlap, take the offsets into account.
8192 Don't use EMACS_INT for small values where int suffices.
8193 When checking for overlap, fix a typo: ZV was used where
8194 ZV_BYTE was intended.
8195 (Fwrite_region): Don't assume off_t fits into 'long'.
8196 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8198 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8200 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8202 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8204 sprintf-related integer and memory overflow issues (Bug#9412).
8206 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8207 (esprintf, exprintf, evxprintf): New functions.
8208 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8209 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8210 (modify_event_symbol): Do not assume that the length of
8211 name_alist_or_stem is safe to alloca and fits in int.
8212 (Fexecute_extended_command): Likewise for function name and binding.
8213 (Frecursion_depth): Wrap around reliably on integer overflow.
8214 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8215 since some callers pass EMACS_INT values.
8216 (Fsingle_key_description): Don't crash if symbol name contains more
8217 than MAX_ALLOCA bytes.
8218 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8219 (get_minibuffer): Arg is now EMACS_INT, not int.
8220 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8221 (esprintf, exprintf, evxprintf): New decls.
8222 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8224 * dbusbind.c (signature_cat): New function.
8225 (xd_signature, Fdbus_register_signal):
8226 Do not overrun buffer; instead, report string overflow.
8228 * dispnew.c (add_window_display_history): Don't overrun buffer.
8229 Truncate instead; this is OK since it's just a log.
8231 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8232 even if the time zone offset is outlandishly large.
8233 Don't mishandle offset == INT_MIN.
8235 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8236 when creating daemon; the previous buffer-overflow check was incorrect.
8238 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8239 which has the guts of the old verror function.
8241 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8242 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8244 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8245 (font_unparse_xlfd): Don't blindly alloca long strings.
8246 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8247 fits in int, when using sprintf. Use single snprintf to count
8248 length of string rather than counting it via multiple sprintfs;
8249 that's simpler and more reliable.
8250 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8251 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8252 sprintf, in case result does not fit in int.
8254 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8255 (fontset_from_font): Print it.
8257 * frame.c (tty_frame_count): Now printmax_t, not int.
8258 (make_terminal_frame, set_term_frame_name): Print it.
8259 (x_report_frame_params): In X, window IDs are unsigned long,
8260 not signed long, so print them as unsigned.
8261 (validate_x_resource_name): Check for implausibly long names,
8262 and don't assume name length fits in 'int'.
8263 (x_get_resource_string): Don't blindly alloca invocation name;
8264 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8267 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8268 (xg_check_special_colors, xg_set_geometry):
8269 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8271 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8272 Use esprintf, not sprintf, in case result does not fit in int.
8274 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8275 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8276 it as a large positive number.
8277 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8278 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8280 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8281 in case result does not fit in int.
8283 * print.c (float_to_string): Detect width overflow more reliably.
8284 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8285 buffer overrun. Don't assume list length fits in 'int'. Treat
8286 print length of 0 as 0, not as infinity; to be consistent with other
8287 uses of print length in this function. Don't overflow print length
8288 index. Don't assume hash table size fits in 'long', or that
8289 vectorlike size fits in 'unsigned long'.
8291 * process.c (make_process): Use printmax_t, not int, to format
8292 process-name gensyms.
8294 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8296 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8297 to avoid potential buffer overrun.
8299 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8300 if X resource line is longer than 512 bytes.
8302 * xfns.c (x_window): Make sprintf buffer a bit bigger
8303 to avoid potential buffer overrun.
8305 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8307 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8309 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8311 Integer overflow fixes for scrolling, etc.
8312 Without these, Emacs silently mishandles large integers sometimes.
8313 For example, "C-u 4294967297 M-x recenter" was treated as if
8314 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8316 * xdisp.c (try_window_id): Check Emacs fixnum range before
8317 converting to 'int'.
8319 * window.c (window_scroll_line_based, Frecenter):
8320 Check that an Emacs fixnum is in range before assigning it to 'int'.
8321 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8322 values converted from Emacs fixnums.
8323 (Frecenter): Don't wrap around a line count if it is out of 'int'
8324 range; instead, treat it as an extreme value.
8325 (Fset_window_configuration, compare_window_configurations):
8326 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8328 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8329 that can exceed INT_MAX. Check that EMACS_INT value is in range
8330 before assigning it to the (possibly-narrower) index.
8331 (match_limit): Don't assume that a fixnum can fit in 'int'.
8333 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8336 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8337 (Fvertical_motion): Don't wrap around LINES values that don't fit
8338 in 'int'. Instead, treat them as extreme values. This is good
8339 enough for windows, which can't have more than INT_MAX lines anyway.
8341 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8343 * Require libxml/parser.h to avoid compilation warning.
8345 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8347 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8348 since this reportedly can destroy thread storage.
8350 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8352 * syntax.c (find_defun_start): Update all cache variables if
8353 exiting early (Bug#9401).
8355 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8357 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8359 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8360 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8361 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8363 * term.c (tty_append_glyph): New function.
8364 (produce_stretch_glyph): Static function and its prototype deleted.
8366 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8369 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8371 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8372 when checking :margin (Bug#9390).
8373 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8374 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8375 so that the name doesn't mislead. All uses changed.
8377 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8379 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8382 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8384 * xdisp.c (move_it_to): Don't bail out early when reaching
8385 position beyond to_charpos, if we are scanning backwards.
8386 (move_it_vertically_backward): When DY == 0, make sure we get to
8387 the first character in the line after the newline.
8389 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8391 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8392 (ccl_driver): Do not generate an out-of-range pointer.
8393 (Fccl_execute_on_string): Remove unnecessary check for
8394 integer overflow, noted by Stefan Monnier in
8395 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8396 Remove a FIXME that didn't need fixing.
8397 Simplify the newly-introduced buffer reallocation code.
8399 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8401 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8403 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8405 Integer and memory overflow issues (Bug#9196).
8407 * doc.c (get_doc_string): Rework so that
8408 get_doc_string_buffer_size is the actual buffer size, rather than
8409 being 1 less than the actual buffer size; this makes xpalloc more
8412 * image.c (x_allocate_bitmap_record, cache_image):
8413 * xselect.c (Fx_register_dnd_atom):
8414 Simplify previous changes by using xpalloc.
8416 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8417 since either will do and ptrdiff_t is convenient with xpalloc.
8419 * charset.c (charset_table_size)
8420 (struct charset_sort_data.priority): Now ptrdiff_t.
8421 (charset_compare): Don't overflow if priorities differ greatly.
8422 (Fsort_charsets): Don't assume list length fits in int.
8423 Check for size-calculation overflow when allocating sort data.
8424 (syms_of_charset): Allocate an initial charset table that is
8425 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8427 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8429 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8430 The actual value is always <= INT_MAX, and leaving it unsigned made
8431 overflow checking harder.
8433 * dispextern.h (struct glyph_matrix.rows_allocated)
8434 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8435 with xpalloc. The values are still always <= INT_MAX.
8437 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8439 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8440 (SAFE_NALLOCA): New macro.
8442 * region-cache.c (struct boundary.pos, find_cache_boundary)
8443 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8444 (set_cache_region, invalidate_region_cache)
8445 (revalidate_region_cache, know_region_cache, region_cache_forward)
8446 (region_cache_backward, pp_cache):
8447 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8448 so that ptrdiff_t * can be passed to xpalloc.
8449 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8450 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8451 (pp_cache): Don't assume cache_len fits in int.
8452 * region-cache.h: Adjust extern decls to match.
8454 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8455 EMACS_INT, since either will do, for xpalloc.
8457 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8458 (xnmalloc, xnrealloc, xpalloc): New functions.
8460 * bidi.c (bidi_shelve_header_size): New constant.
8461 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8462 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8464 * bidi.c (bidi_cache_shrink):
8465 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8467 Don't update size of array until after memory allocation succeeds,
8468 because xmalloc/xrealloc may not return.
8469 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8470 now that we have proper integer overflow checking.
8471 (record_overlay_string, overlay_strings): Catch overflows when
8472 calculating size of overlay_str_buf.
8474 * callproc.c (Fcall_process): Check for size overflow when
8475 calculating size of args2.
8476 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8477 Normally we prefer signed values, but sticking with ptrdiff_t would
8478 require adding more-complicated checks.
8480 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8481 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8482 Redo buffer-overflow calculations to avoid integer overflow.
8483 Add a FIXME comment where memory seems to be over-allocated.
8485 * character.c (Fstring): Check for size-calculation overflow.
8487 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8488 unnecessary integer overflow. Check for size overflow.
8489 (encode_coding_object): Don't update size until xmalloc succeeds.
8491 * composite.c (get_composition_id): Check for overflow in glyph
8492 length calculations.
8494 Integer and memory overflow fixes for display code.
8495 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8496 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8497 (scrolling_window): Check for overflow in size calculations.
8498 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8499 Don't assume glyph table len fits in int.
8500 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8501 (row_table_size): Now ptrdiff_t, not int.
8502 (scrolling_window): Avoid overflow in size calculations.
8503 Don't update size until allocation succeeds.
8504 * fns.c (concat): Check for overflow in size calculations.
8505 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8506 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8507 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8509 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8510 (get_doc_string): Check for size calculation overflow.
8511 Don't update size until allocation succeeds.
8512 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8513 EMACS_INT, where ptrdiff_t will do.
8514 (Fsubstitute_command_keys): Check for string overflow.

8518 (message_length): Now ptrdiff_t, not int.
8519 (Fmessage_box): Don't update size until allocation succeeds.
8520 Don't assume message length fits in int.
8521 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8523 * emacs.c (main): Do not reallocate argv, since there is a null at
8524 the end that can be overwritten, and this way there's no need to
8525 worry about size-calculation overflow.
8526 (sort_args): Check for size-calculation overflow.
8528 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8530 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8532 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8533 (x_set_scroll_bar_width, x_figure_window_size):
8534 Check for integer overflow.
8535 (x_set_alpha): Do not assume XINT fits in int.
8537 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8538 This is for the members text_lines, text_cols, total_lines, total_cols,
8539 where the system imposes an 'int' limit.
8541 * fringe.c (Fdefine_fringe_bitmap):
8542 Don't update size until alloc works.
8544 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8545 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8547 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8548 Check for size-calculation overflow.
8549 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8550 do, as we prefer signed integers.
8551 (id_to_widget.max_size, id_to_widget.used)
8552 (xg_store_widget_in_map, xg_remove_widget_from_map)
8553 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8554 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8555 Use and return ptrdiff_t, not int.
8556 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8557 * gtkutil.h: Change prototypes to match the above.
8559 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8560 are duplicate now that they've been promoted to lisp.h.
8561 (x_allocate_bitmap_record, x_alloc_image_color)
8562 (make_image_cache, cache_image, xpm_load):
8563 Don't update size until alloc is done.
8564 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8566 Check for size calculation overflow.
8567 (ct_colors_allocated_max): New constant.
8568 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

8573 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8574 Use ptrdiff_t, not int, to count maps.
8575 (read_char_minibuf_menu_prompt): Check for overflow in size
8576 calculations. Don't update size until allocation succeeds.

8588 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8590 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8591 Now ptrdiff_t, not int.
8592 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
8593 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
8595 * process.c (Fnetwork_interface_list): Check for overflow
8596 in size calculation.
8598 * region-cache.c (move_cache_gap): Check for size calculation overflow.

8601 overflow. Don't bother calling xmalloc when xrealloc will do.
8603 * search.c (Freplace_match): Check for size calculation overflow.
8604 (Fset_match_data): Don't assume list lengths fit in 'int'.
8606 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8607 for command line length. Do not attempt to address one before the
8608 beginning of an array, as that's not portable.

8611 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8613 (encode_terminal_code, calculate_costs): Check for size
8614 calculation overflow.

8626 Don't update size until alloc done.
8627 Redo size calculations to avoid overflow.

8639 (cache_face): Treat size calculation overflows as if they were
8640 memory exhaustion (the usual treatment), rather than aborting.
8642 * xfns.c (x_encode_text, x_set_name_internal)
8643 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8644 sizes, since they can exceed INT_MAX in size. Check for size
8645 calculation overflow.
8647 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8648 (xg_select): Check for size calculation overflow.
8649 Don't update size until alloc done.
8651 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8652 as sprintf is limited to int lengths.
8654 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8655 (X_LONG_MIN): New macros.
8656 Use them to make the following changes clearer.
8657 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8658 This change doesn't affect the value now, but it may help remind
8659 future maintainers not to raise the value too much later.
8660 (SELECTION_QUANTUM): Remove, replacing with ...
8661 (selection_quantum): ... new function, which avoids overflow.
8663 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8664 assumption that selection length fits in 'int'.
8665 (x_reply_selection_request, x_handle_selection_request)
8666 (x_get_window_property, receive_incremental_selection)
8667 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8668 (lisp_data_to_selection_data, clean_local_selection_data):
8669 Use ptrdiff_t, not int, to record length of selection.
8670 (x_reply_selection_request, x_get_window_property)
8671 (receive_incremental_selection, x_property_data_to_lisp):
8672 Redo calculations to avoid overflow.
8673 (x_reply_selection_request): When sending hint, ceiling it at
8674 X_LONG_MAX rather than relying on wraparound overflow to send
8676 (x_get_window_property, receive_incremental_selection)
8677 (lisp_data_to_selection_data, x_property_data_to_lisp):
8678 Check for size-calculation overflow.
8679 (x_get_window_property, receive_incremental_selection)
8680 (lisp_data_to_selection_data, Fx_register_dnd_atom):
8681 Don't store size until memory allocation succeeds.
8682 (x_get_window_property): Plug memory leak on memory exhaustion.
8683 Don't double-block input; malloc is safe here. Don't assume 2**34
8684 - 4 fits in unsigned long. Add an xassert to check
8685 XGetWindowProperty overflow. Be more careful about overflow
8686 calculations, and distinguish size from memory overflow better.
8687 (receive_incremental_selection): When tracing, don't assume
8688 unsigned int is less than INT_MAX.
8689 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8690 harmful) conversions of unsigned short to int.
8691 (lisp_data_to_selection_data): Don't assume that integers
8692 in the range -65535 through -1 fit in an X unsigned short.
8693 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8694 result parameters unless successful. Rely on cons_to_unsigned
8695 to report problems with elements; the old code wasn't right anyway.
8696 (x_check_property_data): Check for int overflow; we cannot use
8697 a wider type due to X limits.
8698 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8700 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
8702 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
8703 (x_term_init): Check for size calculation overflow.
8704 (x_color_cells): Don't store size until memory allocation succeeds.
8705 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
8706 Don't assume alloca size is less than MAX_ALLOCA.
8707 (x_term_init): Don't assume length fits in int (sprintf is limited

8717 Use ptrdiff_t, not int, for composition IDs.
8718 * composite.c (get_composition_id): Check for integer overflow.
8719 * composite.h: Adjust prototypes to match the above changes.
8721 Use ptrdiff_t for hash table indexes.

8729 * image.c (xpm_get_color_table_h):
8730 * lisp.h (hash_lookup, hash_put):
8731 * minibuf.c (Ftest_completion):
8732 Use ptrdiff_t for hash table indexes, not int (which is too
8733 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8734 32-bit --with-wide-int hosts).
8736 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8737 Add a FIXME comment about memory leaks.
8738 (syms_of_charset): Don't assume xmalloc returns.
8740 Don't assume that stated character widths fit in int.
8741 * character.c (Fchar_width, c_string_width, lisp_string_width):
8742 * character.h (CHAR_WIDTH):
8743 * indent.c (MULTIBYTE_BYTES_WIDTH):
8744 Use sanitize_char_width to avoid undefined and/or bad behavior
8745 with outlandish widths.
8746 * character.h (sanitize_tab_width): Rename from sanitize_width,
8747 now that we have two such functions. All uses changed.
8748 (sanitize_char_width): New inline function.
8750 Don't assume that tab-width fits in int.
8751 * character.h (sanitize_width): New inline function.
8752 (SANE_TAB_WIDTH): New macro.
8753 (ASCII_CHAR_WIDTH): Use it.
8754 * indent.c (sane_tab_width): Remove. All uses replaced by
8755 SANE_TAB_WIDTH (current_buffer).
8756 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
8758 * fileio.c: Integer overflow issues with file modes.
8759 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
8761 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

8765 * xterm.c: Don't go over XClientMessageEvent limit.
8766 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8767 (x_send_scroll_bar_event): Likewise. Check that the size does not
8768 exceed limits imposed by XClientMessageEvent, as well as the usual
8769 ptrdiff_t and size_t limits.
8771 * keyboard.c: Overflow, signedness and related fixes.
8772 (make_lispy_movement): Use same integer type in forward decl
8773 that is used in the definition.
8774 (read_key_sequence, keyremap_step):
8775 Change bufsize argument back to int, undoing my 2011-03-30 change.
8776 We prefer signed types, and int is wide enough here.
8777 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8778 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8779 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8780 length, not size_t. Use ptrdiff_t for index, not int.
8781 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8782 possibility of integer overflow.
8784 Overflow, signedness and related fixes for images.
8786 * dispextern.h (struct it.stack[0].u.image.image_id)
8787 (struct_it.image_id, struct image.id, struct image_cache.size)

8793 * nsmenu.m (update_frame_tool_bar):
8794 * xdisp.c (calc_pixel_width_or_height):
8795 * xfns.c (image_cache_refcount):
8796 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8797 on typical 64-bit hosts.
8799 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8800 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8805 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8806 (lookup_image): Remove unnecessary tests.
8807 (xbm_image_p): Locals are now of int, not EMACS_INT,
8808 since parse_image_check makes sure they fit into int.
8809 (png_load, gif_load, svg_load_image):
8810 Prefer int to unsigned where either will do.
8811 (tiff_handler): New function, combining the cores of the
8812 old tiff_error_handler and tiff_warning_handler.
8813 This function is rewritten to use vsnprintf and thereby avoid
8814 stack buffer overflows. It uses only the features of vsnprintf
8815 that are common to both POSIX and native Microsoft.
8816 (tiff_error_handler, tiff_warning_handler): Use it.
8817 (tiff_load, gif_load, imagemagick_load_image):
8818 Don't assume :index value fits in 'int'.
8819 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8820 (imagemagick_load_image): Check that crop parameters fit into
8821 the integer types that MagickCropImage accepts. Don't assume
8822 Vimagemagick_render_type has a nonnegative value. Don't assume
8823 size_t fits in 'long'.
8824 (gs_load): Use printmax_t to print the widest integers possible.
8825 Check for integer overflow when computing image height and width.
8827 2011-08-26 Eli Zaretskii <eliz@gnu.org>
8829 * xdisp.c (redisplay_window): Don't force window start if point
8830 will be invisible in the resulting window. (Bug#9324)
8832 2011-08-25 Eli Zaretskii <eliz@gnu.org>
8834 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8835 the display spec is of the form `(space ...)'.
8836 (handle_display_spec): Return the value returned by
8837 handle_single_display_spec, not just 1 or zero.
8838 (handle_single_display_spec): If the display spec is of the form
8839 `(space ...)', and specifies display in the text area, return 2
8841 (try_cursor_movement): Check for the need to scroll more
8842 accurately, and prefer exact match for point under bidi.
8843 Don't advance `row' beyond the last row of the window.
8845 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8846 into disp_prop; all users changed.
8848 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
8849 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
8850 for the text covered by the display property.
8852 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
8854 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

8860 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
8861 buffers, return left-to-right.
8862 (set_cursor_from_row): Consider candidate row a win if its glyph
8863 represents a newline and point is on that newline. Fixes cursor
8864 positioning on the newline at EOL of R2L text within L2R
8865 paragraph, and vice versa.
8866 (try_cursor_movement): Check continued rows, in addition to
8867 continuation rows. Fixes unwarranted scroll when point enters a
8868 continued line of R2L text within an L2R paragraph, or vice versa.
8869 (cursor_row_p): Consider the case of point being equal to
8870 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8871 from the end of a short line to the beginning of a continued line
8872 of R2L text within L2R paragraph.
8873 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8874 composed characters.
8876 * bidi.c (bidi_check_type): Use xassert.
8877 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
8880 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8882 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
8885 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
8887 * nsfont.m (ns_otf_to_script): Fix typo.
8889 2011-08-22 Kenichi Handa <handa@m17n.org>
8891 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8892 extra slot even if the purpose is char-code-property-table.
8894 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8896 * xdisp.c (redisplay_window): When computing centering_position,
8897 account for the height of the header line. (Bug#8874)
8899 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8900 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8901 candidate is selected by the mouse, and that candidate has a
8902 composed character under the mouse.
8904 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8905 coordinates reported by pos-visible-in-window-p for a composed
8906 character in column zero.
8908 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8910 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8912 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8914 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8915 consider it a hit if to_charpos is anywhere in the range of the
8916 composed buffer positions.
8918 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8920 * image.c (gif_load): Don't assume that each subimage has the same
8921 dimensions as the base image. Handle disposal method that is
8922 "undefined" by the gif spec (Bug#9335).
8924 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8926 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8927 (Fcondition_case): Document `debug' symbol in error handler.
8929 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8931 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8932 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8933 from an Org mode buffer to a Speedbar frame.
8935 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8936 a composition, take its buffer position from IT->cmp_it.charpos.
8937 Fixes cursor positioning at the beginning of a line that begins
8938 with a composed character.
8940 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8942 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8943 character bidirectional type, use STRONG_L instead. Fixes crashes
8944 in a buffer produced by `describe-categories'.
8946 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8947 members before the level stack, so they would be saved and
8948 restored when copying iterator state. Fixes incorrect reordering
8949 around TABs covered by display properties.
8951 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8953 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
8955 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
8957 * eval.c (internal_condition_case, internal_condition_case_1)
8958 (internal_condition_case_2, internal_condition_case_n):
8959 Remove unnecessary aborts (Bug#9081).
8961 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8963 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8964 has no `load' handler, try opening the file locally. (Bug#9311)
8966 2011-08-16 Ken Brown <kbrown@cornell.edu>
8968 * gmalloc.c: Expand comment.
8970 2011-08-16 Eli Zaretskii <eliz@gnu.org>
8972 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
8973 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
8975 2011-08-16 Ken Brown <kbrown@cornell.edu>
8977 Fix memory allocation problems in Cygwin build (Bug#9273).
8979 * unexcw.c ( __malloc_initialized): Declare external variable.
8980 (fixup_executable): Force the dumped emacs to reinitialize malloc.
8982 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
8984 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8986 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8988 [CYGWIN] (special_realloc): New function.
8989 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8990 requests to realloc storage in the static heap.
8992 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
8994 * bidi.c (bidi_initialize): Remove unused local.

8999 * biditype.h: Remove file.
9000 * makefile.w32-in ($(BLD)/bidi.$(O)):
9001 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
9003 * dispextern.h: Fix a typo in the comment to bidi_type_t.
9005 * chartab.c: Improve commentary for the uniprop_table API.
9007 * bidi.c (bidi_paragraph_init): Support zero value of
9008 bidi_ignore_explicit_marks_for_paragraph_level.
9009 (bidi_initialize): Use uniprop_table instead of including
9010 biditype.h and bidimirror.h.
9012 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
9013 coordinates of the iterator when restoring from ppos_it.
9016 2011-08-14 Kenichi Handa <handa@m17n.org>
9018 * process.c (create_process): Call setup_process_coding_systems
9019 after the pid of the process is set to -1 (Bug#8162).
9021 2011-08-14 Eli Zaretskii <eliz@gnu.org>
9023 * xdisp.c (move_it_in_display_line_to): Don't invoke
9024 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
9025 ppos_it. Fixes vertical cursor motion when line beginning is
9026 covered by an image. (Bug#9296)
9028 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
9030 * nsterm.h (ns_run_ascript): Declare.
9031 (NSAPP_DATA2_RUNASSCRIPT): Define.
9033 * nsfns.m (as_script, as_result, as_status): New static variables.
9034 (ns_run_ascript): New function.
9035 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
9036 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
9037 the event loop. Get status from as_status (Bug#7276).
9039 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9040 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
9041 the event loop (Bug#7276).
9043 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
9045 * gnutls.c (QCgnutls_bootprop_priority)
9046 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
9047 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
9048 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

9050 (QCgnutls_bootprop_verify_hostname_error)
9051 (QCgnutls_bootprop_callbacks_verify): Rename from
9052 Qgnutls_bootprop_..., all uses changed.
9054 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
9057 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
9059 * xfaces.c (Qframe_set_background_mode): Now static.
9060 * dispextern.h (Qframe_set_background_mode): Remove decl.
9062 * process.c (Fnetwork_interface_info): Declare local only if needed.
9064 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
9066 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
9067 (Fnetwork_interface_list): Allocate in increments of bytes instead
9068 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
9069 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
9071 (struct ifflag_def): notrailers is smart on OSX.
9072 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9073 Get hardware address with getifaddrs if available.
9075 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9077 * xdisp.c (iterate_out_of_display_property): xassert that
9078 IT->position is set to within IT->object's boundaries. Break from
9079 the loop as soon as EOB is reached; avoids infloops in redisplay
9080 when IT->position is set up wrongly due to some bug.
9081 Set IT->current to match the bidi iterator unconditionally.
9082 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9083 entry. Force push_it to save on the stack the current
9084 buffer/string position, to be restored by pop_it. Fix flags in
9085 the iterator structure wrt the object coming from a display
9086 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9087 properties. (Bug#9284)
9089 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9091 * fontset.c (fontset_get_font_group): Add proper type checks.
9094 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

9103 * xdisp.c (forward_to_next_line_start): Allow to use the
9104 no-display-properties-and-no-overlays under bidi display.
9105 Set disp_pos in the bidi iterator to avoid searches for display
9106 properties and overlays.
9108 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9110 * editfns.c (Fset_time_zone_rule): Document relationship with the
9113 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9114 the font entity extracted from the cache (Bug#8109).
9116 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9118 * composite.c (autocmp_chars): Don't reset point. That is done by
9119 restore_point_unwind (Bug#5984).
9121 2011-08-07 Juri Linkov <juri@jurta.org>
9123 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9124 to show the arg `TIME' instead of `TIMEVAL'.
9126 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9128 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9129 display property strides EOL and includes a newline, as in
9130 longlines-mode. (Bug#9254)
9131 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9132 word-wrap under bidirectional display. (Bug#9224)
9134 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9135 is non-zero, even if the data buffer is NULL. Fixes a crash in
9136 vertical-motion with longlines-mode. (Bug#9254)
9138 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9140 * bidi.c <bidi_cache_total_alloc>: Now static.
9141 (bidi_initialize): Initialize bidi_cache_total_alloc.
9143 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9146 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9147 amount allocated this far in `bidi_cache_total_alloc'.
9148 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9149 non-zero, only free the data buffer without restoring the cache
9150 contents. All callers changed.
9152 * dispextern.h (bidi_unshelve_cache): Update prototype.
9154 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9155 (move_it_in_display_line, move_it_to)
9156 (move_it_vertically_backward, move_it_by_lines): Replace the call
9157 to xfree to an equivalent call to bidi_unshelve_cache.
9158 (move_it_in_display_line_to): Fix logic of returning
9159 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9161 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9163 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9164 came from a string character with a `cursor' property. (Bug#9229)
9166 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9168 * Makefile.in (LIB_PTHREAD): New variable.
9169 (LIBES): Add LIB_PTHREAD (Bug#9216).
9171 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9172 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9174 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9176 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9178 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9180 * xterm.c (x_find_topmost_parent): New function.
9181 (x_set_frame_alpha): Find topmost parent window with
9182 x_find_topmost_parent and set the property there also (bug#9181).
9183 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9185 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9187 * callproc.c (Fcall_process): Avoid vfork clobbering
9188 the local vars buffer, coding_systems, current_dir.
9190 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9192 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9194 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9196 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9197 so that it is not optimized away.
9199 * xdisp.c (compute_display_string_pos): Remove unused local.
9201 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9203 Fix slow cursor motion and scrolling in large buffers with
9204 selective display, like Org Mode buffers. (Bug#9218)
9206 * dispextern.h (struct bidi_it): New member disp_prop_p.
9208 * xdisp.c: Remove one-slot cache of display string positions.
9209 (compute_display_string_pos): Accept an additional argument
9210 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9211 for a display string or property. If found, set DISP_PROP_P
9214 * bidi.c (bidi_fetch_char): Accept an additional argument
9215 DISP_PROP_P, and pass it to compute_display_string_pos.
9216 Only handle text covered by a display string if DISP_PROP_P is returned
9217 non-zero. All callers of bidi_fetch_char changed.
9219 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9221 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9223 2010-12-03 Don March <don@ohspite.net>
9225 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9226 last character M-[char] is translated to ESC [char] (bug#7541).
9228 2011-08-02 Kenichi Handa <handa@m17n.org>
9230 * lisp.h (uniprop_table): Extern it.
9232 * chartab.c (uniprop_table): Make it non-static.
9234 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9236 * xdisp.c (forward_to_next_line_start): Accept additional argument
9237 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9239 (reseat_at_next_visible_line_start): Use the bidi iterator state
9240 returned by forward_to_next_line_start to restore the state of
9241 it->bidi_it after backing up to previous newline. (Bug#9212)
9243 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9245 * regex.c (re_comp): Protoize.
9246 (re_exec): Fix return type.
9247 (regexec): Fix type of `ret'. (Bug#9203)
9249 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9251 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9252 This is needed if max-image-size is a floating-point number.
9254 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9256 * print.c (print_object): Print empty symbol as ##.
9258 * lread.c (read1): Read ## as empty symbol.
9260 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9262 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9263 setting frame foreground color (Bug#9175).
9264 (x_set_background_color): Likewise.
9266 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9267 contents (Bug#9176).
9268 (EmacsTooltip -init): Remove bezels and add shadows to
9271 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9272 or scroll bar (Bug#8470).
9274 * nsfont.m (nsfont_open): Remove assignment to voffset and
9275 unnecessary vars hshink, expand, hd, full_height, min_height.
9276 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9278 * nsterm.h (nsfont_info): Remove voffset field.
9280 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9282 Implement strike-through and overline on NextStep (Bug#8863).
9284 * nsfont.m (nsfont_open): Use underline position provided by font,
9285 instead of hard-coded value of 2.
9286 (nsfont_draw): Call ns_draw_text_decoration instead.
9288 * nsterm.h: Add declaration for ns_draw_text_decoration.
9290 * nsterm.m (ns_draw_text_decoration): New function for drawing
9291 underline, overline, and strike-through.
9292 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9293 ns_draw_text_decoration. Change treatment of cursor drawing to
9294 accommodate underlining, etc.
9296 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9298 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9301 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9303 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9304 Without this fix, if a signal arrives just after memory fills up,
9305 'malloc' might be invoked reentrantly.
9307 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9308 In other words, assume that every image size is allowed, on non-X
9309 hosts. This assumption is probably wrong, but it lets Emacs compile.
9311 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9313 * regex.c (re_iswctype): Convert return values to boolean.
9315 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9317 * xdisp.c (compute_display_string_pos): Don't use cached display
9318 string position if the buffer had its restriction changed.
9321 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9323 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9325 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9327 Integer signedness and overflow and related fixes. (Bug#9079)
9329 * bidi.c: Integer size and overflow fixes.
9330 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9331 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9332 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9333 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9334 (bidi_find_other_level_edge):
9335 Use ptrdiff_t instead of EMACS_INT where either will do.
9336 This works better on 32-bit hosts configured --with-wide-int.
9337 (bidi_cache_ensure_space): Check for size-calculation overflow.
9338 Use % rather than repeated addition, for better worst-case speed.
9339 Don't set bidi_cache_size until after xrealloc returns, because it
9341 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9342 (bidi_cache_ensure_space): Also check that the bidi cache size
9343 does not exceed that of the largest Lisp string or buffer. See Eli
9344 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9346 * alloc.c (__malloc_size_t): Remove.
9347 All uses replaced by size_t. See Andreas Schwab's note
9348 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9350 * image.c: Improve checking for integer overflow.
9351 (check_image_size): Assume that f is nonnull, since
9352 it is always nonnull in practice. This is one less thing to
9353 worry about when checking for integer overflow later.
9354 (x_check_image_size): New function, which checks for integer
9355 overflow issues inside X.
9356 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9357 This removes the need for a memory_full check.
9358 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9359 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9360 (xbm_read_bitmap_data): Change locals back to 'int', since
9361 their values must fit in 'int'.
9362 (xpm_load_image, png_load, tiff_load):
9363 Invoke x_create_x_image_and_pixmap earlier,
9364 to avoid much needless work if the image is too large.
9365 (tiff_load): Treat overly large images as if
9366 x_create_x_image_and_pixmap failed, not as malloc failures.
9367 (gs_load): Use x_check_image_size.
9369 * gtkutil.c: Omit integer casts.
9370 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9371 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9373 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9375 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9376 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9377 would wrongly return t on a 64-bit host.
9379 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9380 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9381 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9382 and therefore cause GCC to emit a bogus diagnostic in some cases.
9384 * image.c: Integer signedness and overflow and related fixes.
9385 This is not an exhaustive set of fixes, but it's time to
9386 record what I've got.
9387 (lookup_pixel_color, check_image_size): Remove redundant decls.
9388 (check_image_size): Don't assume that arbitrary EMACS_INT values
9389 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9390 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9391 (tiff_load, imagemagick_load_image):
9392 Check for overflow in size calculations.
9393 (x_create_x_image_and_pixmap): Remove unnecessary test for
9394 xmalloc returning NULL; that can't happen.
9395 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9396 (xpm_color_bucket): Use better integer hashing function.
9397 (xpm_cache_color): Don't possibly over-allocate memory.
9398 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9399 (gif_memory_source):
9400 Use ptrdiff_t, not int or size_t, to record sizes.
9401 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9402 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9403 either works, as we prefer signed integers.
9404 (tiff_read_from_memory, tiff_write_from_memory):
9405 Return tsize_t, not size_t, since that's what the TIFF API wants.
9406 (tiff_read_from_memory): Don't fail simply because the read would
9407 go past EOF; instead, return a short read.
9408 (tiff_load): Omit no-longer-needed casts.
9409 (Fimagemagick_types): Don't assume size fits into 'int'.
9411 Improve hashing quality when configured --with-wide-int.
9412 * fns.c (hash_string): New function, taken from sxhash_string.
9413 Do not discard information about ASCII character case; this
9414 discarding is no longer needed.
9415 (sxhash-string): Use it. Change sig to match it. Caller changed.
9416 * lisp.h: Declare it.
9417 * lread.c (hash_string): Remove, since we now use fns.c's version.
9418 The fns.c version returns a wider integer if --with-wide-int is
9419 specified, so this should help the quality of the hashing a bit.
9421 * emacs.c: Integer overflow minor fix.
9422 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9423 Define only if GNU_LINUX.
9424 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9426 * dispnew.c: Integer signedness and overflow fixes.
9427 Remove unnecessary forward decls, that were a maintenance hassle.
9428 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9430 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9431 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9432 (prepare_desired_row, line_draw_cost):
9433 Use int, not unsigned, where either works.
9434 (save_current_matrix, restore_current_matrix):
9435 Use ptrdiff_t, not size_t, where either works.
9436 (init_display): Check for overflow more accurately, and without
9437 relying on undefined behavior.
9439 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9440 Remove, replacing with the new symbols in lisp.h. All uses changed.
9441 * fileio.c (make_temp_name):
9442 * filelock.c (lock_file_1, lock_file):
9443 * xdisp.c (message_dolog):
9444 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9445 Use pMd etc. instead.
9446 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9447 replacing the pWIDE etc. symbols removed from editfns.c.
9449 * keyboard.h (num_input_events): Now uintmax_t.
9450 This is (very slightly) less likely to mess up due to wraparound.
9453 * buffer.c: Integer signedness fixes.
9454 (alloc_buffer_text, enlarge_buffer_text):
9455 Use ptrdiff_t rather than size_t when either will do, as we prefer
9458 * alloc.c: Integer signedness and overflow fixes.
9459 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9460 (__malloc_size_t): Default to size_t, not to int.
9461 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9462 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9463 Prefer ptrdiff_t to size_t when either would do, as we prefer
9465 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9466 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9467 Now const. Initialize with values that are in range even if char
9469 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9470 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9471 These functions do the right thing with sizes > 2**32.
9472 (check_depth): Now ptrdiff_t, not int.
9473 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9474 Adjust to new way of storing sizes. Check for size overflow bugs
9476 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9477 slightly wrong anyway, as it missed one instance of
9478 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9479 (refill_memory_reserve): Omit needless cast to size_t.
9480 (mark_object_loop_halt): Mark as externally visible.
9482 * xselect.c: Integer signedness and overflow fixes.
9483 (Fx_register_dnd_atom, x_handle_dnd_message):
9484 Use ptrdiff_t, not size_t, since we prefer signed.
9485 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9486 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9487 x_dnd_atoms_size and x_dnd_atoms_length.
9489 * doprnt.c: Prefer signed to unsigned when either works.
9491 * doprnt.c (doprnt):
9493 * xdisp.c (vmessage):
9494 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9495 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9496 prefer signed arithmetic to avoid comparison confusion.
9497 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9498 but is a bit tricky.
9500 Assume freestanding C89 headers, string.h, stdlib.h.
9501 * data.c, doprnt.c, floatfns.c, print.c:
9502 Include float.h unconditionally.
9503 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9504 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9505 * regex.c: Likewise for stddef.h, string.h.
9506 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9507 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9508 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9509 (STDC_HEADERS): Remove obsolete defines.
9510 * sysdep.c: Include limits.h unconditionally.
9512 Assume support for memcmp, memcpy, memmove, memset.
9513 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9514 * regex.c (memcmp, memcpy):
9515 Remove; we assume C89 now.
9517 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9518 (__malloc_safe_bcopy): Remove; no longer needed.
9520 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9521 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9522 well either way, and we prefer signed to unsigned.
9524 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9526 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9527 closes the connection while we're reading (bug#9182).
9529 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9531 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9532 are specified (Bug#9168).
9534 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9536 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9537 Found by GCC static checking and --with-wide-int on a 32-bit host.
9539 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9541 * xdisp.c (compute_display_string_pos): Fix logic of caching
9542 previous display string position. Initialize cached_prev_pos to
9543 -1. Fixes slow-down at the beginning of a buffer.
9545 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9547 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9548 for attrs[LFACE_FONTSET_INDEX].
9550 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9552 * xml.c (parse_region): Remove unused local
9553 that was recently introduced.
9555 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9557 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9558 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9560 * xdisp.c (move_it_in_display_line_to): Record the best matching
9561 position for TO_CHARPOS while scanning the line, and restore it on
9562 exit if none of the characters scanned was an exact match.
9563 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9564 when exact match is impossible due to invisible text, and the
9565 lines are truncated.
9567 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9569 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9572 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9574 Fix a significant slow-down of cursor motion with C-n, C-p,
9575 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9576 auto-repeat under bidi redisplay in fontified buffers.
9577 * xdisp.c (compute_stop_pos_backwards): New function.
9578 (next_element_from_buffer): Call compute_stop_pos_backwards to
9579 find a suitable prev_stop when we find ourselves before
9581 (reseat): Don't look for prev_stop, as that could mean a very long
9583 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9584 <cached_disp_overlay_modiff>: Cache for last found display string
9586 (compute_display_string_pos): Return the cached position if asked
9587 about the same buffer in the same area of character positions, and
9588 the buffer wasn't changed since the time the display string
9589 position was cached.
9591 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9593 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9594 is an integer, which is important for empty lines. (Bug#9149)
9596 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9598 * frame.c (Fmodify_frame_parameters): In tty case, update the
9599 default face if necessary (Bug#4238).
9601 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9603 * editfns.c (Fstring_to_char): No need to explain what a character
9604 is in the docstring (Bug#6576).
9606 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9608 * xml.c (parse_region): Make sure we always return a tree.
9610 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9612 * xml.c (parse_region): If a document contains only comments,
9615 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9617 * xml.c (make_dom): Return comments, too.

9622 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9623 and the surrounding thread.
9624 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9625 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9626 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9628 * s/openbsd.h (BROKEN_SIGIO): Define.
9629 * unexelf.c (unexec) [__OpenBSD__]:
9630 Don't update the .mdebug section of the Alpha COFF symbol table.
9632 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9634 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9637 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>

9640 This fixes some race conditions on the permissions of any newly
9643 * alloc.c (valid_pointer_p): Use pipe, not open.
9644 This fixes some permissions issues when debugging.
9646 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9647 If fchown fails to set both uid and gid, try to set just gid,
9648 as that is sometimes allowed. Adjust the file's mode to eliminate
9649 setuid or setgid bits that are inappropriate if fchown fails.
9651 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9653 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9654 to compare Lisp_Objects.
9655 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to

9665 symbol character follows.
9667 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9669 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9670 This works around a problem with the previous change to Fcopy_file.
9671 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9672 and without this change, GCC might complain about discarding
9673 fchown's return value.
9675 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9677 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9679 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9681 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9683 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9685 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9686 it's used from the C level.
9688 * process.c: Use the same condition for POLL_FOR_INPUT in both
9689 keyboard.c and process.c (bug#1858).
9691 2011-07-09 Lawrence Mitchell <wence@gmx.li>

9698 * doc.c (Fsubstitute_command_keys): Revert last change.
9700 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9702 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9703 quotes the next character, and doesn't affect other longer
9704 sequences (bug#8935).
9706 * lread.c (syms_of_lread): Clarify that is isn't only
9707 `eval-buffer' and `eval-defun' that's affected by
9708 `lexical-binding' (bug#8460).
9710 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9712 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9713 bidi redisplay when a line includes both an image and is truncated.

9717 Fix minor problems found by static checking.
9718 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9719 (elsz): Now a signed constant, not a size_t var. We prefer signed
9720 types to unsigned, to avoid integer comparison confusion. Without
9721 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9722 "cannot optimize loop, the loop counter may overflow", a symptom
9724 * indent.c (Fvertical_motion): Mark locals as initialized.
9725 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9727 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9729 * search.c (Fre_search_backward): Mention `case-fold-search' in
9730 all the re_search_* functions (bug#8138).

9750 buffer position was specified. Initialize paragraph_embedding to
9752 (reseat_to_string): Initialize the bidi iterator.
9753 (display_string): If we need to ignore text properties of
9754 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9755 original value of -1 will not work with bidi.)

9759 (compute_display_string_end): Support display properties on Lisp
9761 (init_iterator, reseat_1, reseat_to_string): Initialize the
9762 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9763 when iterating on a string not from display properties).
9764 (compute_display_string_pos, compute_display_string_end):
9765 Fix calculation of the object to scan. Fixes an error when using
9767 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9768 base_level_stop; instead, set base_level_stop to BEGV.
9769 Fixes crashes in vertical-motion.
9770 (next_element_from_buffer): Improve commentary for when
9771 the iterator is before prev_stop.
9772 (init_iterator): Initialize bidi_p from the default value of
9773 bidi-display-reordering, not from buffer-local value. Use the
9774 buffer-local value only if initializing for buffer iteration.
9775 (handle_invisible_prop): Support invisible properties on strings
9776 that are being bidi-reordered.
9777 (set_iterator_to_next): Support bidi reordering of C strings and

9795 parts of next_element_from_buffer, next_element_from_string, and
9796 next_element_from_c_string.
9797 (tool_bar_lines_needed, redisplay_tool_bar)
9798 (display_menu_bar): Force left-to-right direction. Add a FIXME

9813 pushed the iterator stack, restore the internal state of the bidi
9814 iterator by calling bidi_pop_it same number of times.
9815 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9816 and we are bidi-iterating, don't decrement the iterator position;
9817 instead, set the first_elt flag in the bidi iterator, to produce
9819 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9820 (push_display_prop): xassert that we are iterating a buffer.

9853 (back_to_previous_visible_line_start, reseat_1)
9854 (init_iterator): Empty the bidi cache "stack".
9855 (move_it_in_display_line_to): If iterator ended up at

9881 changed. Support iteration over a string. Support strings with
9882 display properties. Support unibyte strings. Fix the type of
9883 `len' according to what STRING_CHAR_AND_LENGTH expects.

9982 The old code sometimes used this field without initializing it.
9984 * alloc.c (gc_sweep): Don't read past end of array.

9990 * character.c (Fcharacterp): Don't advertise optional ignored
9991 argument. (Bug#4026)

10005 * xsettings.c (store_monospaced_changed): Define this function only
10006 if (defined HAVE_GSETTINGS || defined HAVE_GCONF), as it's
10007 not used otherwise.
10009 2011-07-12 Chong Yidong <cyd@stupidchicken.com>
10011 * xdisp.c (Vresize_mini_windows): Minor doc fix (Bug#3300).

10249 (clone_per_buffer_values): Don't assume that

10251 This isn't true in general, and it's particularly not true
10252 if Emacs is configured with --with-wide-int.
10253 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
10254 New macros, used in the buffer.c change.

10290 Random fixes. E.g., (random) never returned negative values.
10291 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10292 subseconds part to the entropy, as that's a bit more random.
10293 Prefer signed to unsigned, since the signedness doesn't matter and
10294 in general we prefer signed. When given a limit, use a
10295 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10296 latter isn't right if USE_2_TAGS_FOR_INTS.
10297 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10298 not 0..VALMASK. Don't discard "excess" bits that random () returns.
10300 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10302 * textprop.c (text_property_stickiness):

10310 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
10311 This is more efficient than Ffile_directory_p and avoids a minor race.
10313 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
10315 * buffer.c (Foverlay_put): Say what the return value is
10318 * fileio.c (barf_or_query_if_file_exists): Check first if the file
10319 is a directory before asking whether to use the file name
10321 (barf_or_query_if_file_exists): Make the "File is a directory"
10322 error be more correct.
10324 * fns.c (Frequire): Remove the mention of the .gz files, since
10325 that's installation-specific, but keep the mention of
10326 `get-load-suffixes'.
10328 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
10330 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

10338 Qgnutls_bootprop_verify_error (which is no longer used).
10340 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
10341 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
10342 Also (re)move comments that are misplaced or no longer relevant.

10367 leave any prefix arg for the up event (Bug#1586).
10369 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
10371 * lread.c (syms_of_lread): Mention single symbols defined by
10372 `defvar' or `defconst' (bug#7154).
10374 * fns.c (Frequire): Mention .el.gz files (bug#7314).
10375 (Frequire): Mention get-load-suffixes.
10377 2011-07-02 Martin Rudalics <rudalics@gmx.at>
10379 * window.h (window): Remove clone_number slot.
10380 * window.c (Fwindow_clone_number, Fset_window_clone_number):

10404 minibuffer-local-filename-must-match-map to Elisp.
10405 (syms_of_keymap): Defsubr make-composed-keymap.
10406 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

10435 (xgselect_initialize): Ditto.
10437 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h

10441 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
10443 * eval.c (struct backtrace): Simplify and port the data structure.
10444 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10445 signed bit field, as this assumption is not portable and it makes
10446 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10447 "char debug_on_exit : 1" as this is not portable either; instead,
10448 use the portable "unsigned int debug_on_exit : 1". Remove unused
10449 member evalargs. Remove obsolete comments about cc bombing out.
10451 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

10617 * print.c (printchar, strout): Check for string overflow.
10618 (PRINTPREPARE, printchar, strout):
10619 Don't set size unless allocation succeeds.
10621 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10622 for sizes. Check for string overflow more accurately.
10623 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10625 * macros.c: Integer and buffer overflow fixes.
10626 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10627 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

10631 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10633 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10635 * lread.c: Integer overflow fixes.
10636 (read_integer): Radix is now EMACS_INT, not int,
10637 to improve quality of diagnostics for out-of-range radices.
10638 Calculate buffer size correctly for out-of-range radices.
10639 (read1): Check for integer overflow in radices, and in
10640 read-circle numbers.
10641 (read_escape): Avoid int overflow.
10642 (Fload, openp, read_buffer_size, read1)
10643 (substitute_object_recurse, read_vector, read_list, map_obarray):
10644 Use ptrdiff_t, not int, for sizes.

10659 2011-06-22 Leo Liu <sdl.web@gmail.com>
10661 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10662 Move to minibuffer.el.
10664 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10666 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10667 The following patches are for when GLYPH_DEBUG && !XASSERT.
10668 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10669 * dispnew.c (flush_stdout):
10670 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10671 Mark as externally visible.
10672 * dispnew.c (check_window_matrix_pointers): Now static.
10673 * dispnew.c (window_to_frame_vpos):
10674 * xfns.c (unwind_create_frame):
10675 * xterm.c (x_check_font): Remove unused local.
10676 * scroll.c (CHECK_BOUNDS):
10677 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10678 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10679 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10680 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10681 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10683 (debug_method_add): Use va_list and vsprintf rather than relying
10684 on undefined behavior with wrong number of arguments.
10685 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10686 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10687 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10688 since we're not interested in debugging glyphs with old libraries.
10689 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10690 GCC 4.6.0's static checking.
10692 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10694 Integer overflow and signedness fixes (Bug#8873).

10710 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10711 (.bitmaps_last, struct x_output.icon_bitmap):
10712 Use ptrdiff_t, not int, for bitmap indexes.
10713 (x_allocate_bitmap_record): Check for size overflow.
10714 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10716 Use ptrdiff_t, not int, for overlay counts.
10717 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10718 * editfns.c (overlays_around, get_pos_property):
10719 * textprop.c (get_char_property_and_overlay):
10720 * xdisp.c (next_overlay_change, note_mouse_highlight):
10721 * xfaces.c (face_at_buffer_position):
10722 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10723 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10724 (Fnext_overlay_change, Fprevious_overlay_change)
10725 (mouse_face_overlay_overlaps, Foverlays_in):
10726 Use ptrdiff_t, not int, for sizes.
10727 (overlays_at, overlays_in): Check for size-calculation overflow.
10729 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10731 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10732 (x_session_initialize): Do not assume string length fits in int.
10734 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10735 This is unlikely, but can occur if DPI is outlandish.
10737 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10738 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10740 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10741 * xrdb.c (magic_file_p, search_magic_path):
10742 Omit last arg SUFFIX; it was always 0. All callers changed.
10743 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10745 * xfont.c (xfont_match): Avoid need for strlen.
10747 * xfns.c: Don't assume strlen fits in int.
10748 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10750 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10751 not unsigned long, as we prefer signed integers. All callers changed.
10752 Detect integer overflow in repeat count.
10753 (message_dolog): Don't assume print length fits in 39 bytes.
10754 (display_mode_element): Don't assume strlen fits in int.
10756 * termcap.c: Don't assume sizes fit in int and never overflow.
10757 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10758 (gobble_line): Check for size-calculation overflow.
10760 * minibuf.c (Fread_buffer):
10761 * lread.c (intern, intern_c_string):
10762 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

10775 * filelock.c: Fix some buffer overrun and integer overflow issues.
10776 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10777 Reformulate so as not to need the command string.
10778 Invoke gzip -cd rather than gunzip, as it's more portable.
10779 (lock_info_type, lock_file_1, lock_file):
10780 Don't assume pid_t and time_t fit in unsigned long.
10781 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10782 (current_lock_owner): Prefer signed type for sizes.
10783 Use memcpy, not strncpy, where memcpy is what is really wanted.
10784 Don't assume (via atoi) that time_t and pid_t fit in int.
10785 Check for time_t and/or pid_t out of range, e.g., via a network share.
10786 Don't alloca where an auto var works fine.
10788 * fileio.c: Fix some integer overflow issues.
10789 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10790 Don't assume string length fits in int.
10791 (directory_file_name): Don't assume string length fits in long.
10792 (make_temp_name): Don't assume pid fits in int, or that its print
10793 length is less than 20.
10795 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10797 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10799 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10801 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.

10805 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10806 (main): Don't invoke strlen when not needed.

10812 (Fgetenv_internal):
10813 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10815 * lread.c (invalid_syntax): Omit length argument.
10816 All uses changed. This doesn't fix a bug, but it simplifies the
10817 code away from its former Hollerith-constant appearance, and it's
10818 one less 'int' to worry about when looking at integer-overflow issues.
10819 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10821 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10822 This didn't break anything, but it didn't help either.
10823 It's confusing to put a bogus integer in a place where the actual
10824 value does not matter.
10825 (LIST_END_P): Remove unused macro and its bogus comment.
10826 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10828 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10829 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10831 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10832 We prefer signed types, and the value cannot exceed the EMACS_INT
10833 range anyway (because otherwise the length would not be representable).
10834 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10835 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10836 This avoids a GCC warning when WIDE_EMACS_INT.
10838 * indent.c (sane_tab_width): New function.
10839 (current_column, scan_for_column, Findent_to, position_indentation)
10840 (compute_motion): Use it. This is just for clarity.
10841 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10843 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10845 * lisp.h (lint_assume): New macro.
10846 * composite.c (composition_gstring_put_cache):
10847 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10849 * editfns.c, insdel.c:
10850 Omit unnecessary forward decls, to simplify future changes.
10852 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10854 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10856 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10857 Use much-faster test for byte-length change.
10858 Don't assume string byte-length fits in 'int'.
10859 Check that character arg fits in 'int'.
10860 (mapcar1): Declare byte as byte, for clarity.
10862 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10864 * fns.c (concat): Catch string overflow earlier.
10865 Do not rely on integer wraparound.
10867 * dispextern.h (struct it.overlay_strings_charpos)
10868 (struct it.selective): Now EMACS_INT, not int.
10869 * xdisp.c (forward_to_next_line_start)
10870 (back_to_previous_visible_line_start)
10871 (reseat_at_next_visible_line_start, next_element_from_buffer):
10872 Don't arbitrarily truncate the value of 'selective' to int.
10874 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10876 * composite.c: Don't truncate sizes to 'int'.
10877 (composition_gstring_p, composition_reseat_it)
10878 (composition_adjust_point): Use EMACS_INT, not int.
10879 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10880 not EMACS_UINT, for indexes.
10882 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10884 * buffer.c: Include <verify.h>.
10885 (struct sortvec.priority, struct sortstr.priority):
10886 Now EMACS_INT, not int.
10887 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10888 (struct sortstr.size, record_overlay_string)
10889 (struct sortstrlist.size, struct sortlist.used):
10890 Don't truncate size to int.
10891 (record_overlay_string): Check for size-calculation overflow.
10892 (init_buffer_once): Check at compile-time, not run-time.

10896 Don't leak an XBM-image-sized buffer
10897 * image.c (xbm_load): Free the image buffer after using it.
10899 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10902 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10903 that Sun C diagnosed.
10904 * fns.c (secure_hash): Fix pointer signedness issue.
10905 * intervals.c (static_offset_intervals): New function.
10906 (offset_intervals): Use it.
10908 2011-06-21 Leo Liu <sdl.web@gmail.com>
10911 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10914 * fns.c (secure_hash): Rename from crypto_hash_function and change
10915 the first arg to accept symbols.
10916 (Fsecure_hash): New primitive.
10917 (syms_of_fns): New symbols.
10919 2011-06-20 Deniz Dogan <deniz@dogan.se>
10921 * process.c (Fset_process_buffer): Clarify return value in
10924 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10926 * dispnew.c (add_window_display_history): Use BVAR.
10928 * xdisp.c (debug_method_add): Use BVAR.
10929 (check_window_end, dump_glyph_matrix, dump_glyph)
10930 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10932 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10935 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10936 check till after the cache is created in init_frame_faces.
10938 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10940 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10942 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10944 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10945 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10946 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10948 Improve buffer-overflow checking (Bug#8873).
10949 * fileio.c (Finsert_file_contents):
10950 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10951 Remove the old (too-loose) buffer overflow checks.
10952 They weren't needed, since make_gap checks for buffer overflow.
10953 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10954 The old code merely checked for Emacs fixnum overflow, and relied
10955 on undefined (wraparound) behavior. The new code avoids undefined
10956 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10958 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10959 Tune. Don't use wider integers than needed. Don't use alloca.
10960 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10962 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10964 * insdel.c, lisp.h (buffer_overflow): New function.
10965 (insert_from_buffer_1, replace_range, replace_range_2):
10966 * insdel.c (make_gap_larger):
10967 * editfns.c (Finsert_char):
10968 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10970 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10972 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10974 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10976 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10977 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10979 * fileio.c: Don't assume EMACS_INT fits in off_t.
10980 (emacs_lseek): New static function.
10981 (Finsert_file_contents, Fwrite_region): Use it.
10982 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10984 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10986 * fns.c: Don't overflow int when computing a list length.
10987 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10988 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10989 truncation on 64-bit hosts. Check for QUIT every
10990 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10991 faster and is responsive enough.
10992 (Flength): Report an error instead of overflowing an integer.
10993 (Fsafe_length): Return a float if the value is not representable
10994 as a fixnum. This shouldn't happen except in contrived situations.
10995 (Fnthcdr, Fsort): Don't assume list length fits in int.
10996 (Fcopy_sequence): Don't assume vector length fits in int.
10998 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10999 (header_size, word_size): New constants.
11000 (allocate_vectorlike): Don't check size overflow here.
11001 (allocate_vector): Check it here instead, since this is the only
11002 caller of allocate_vectorlike that could cause overflow.
11003 Check that the new vector's length is representable as a fixnum.
11005 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11006 The previous code was bogus. For example, next_almost_prime (32)
11007 returned 39, which is undesirable as it is a multiple of 3; and
11008 next_almost_prime (24) returned 25, which is a multiple of 5 so
11009 why was the code bothering to check for multiples of 7?
11011 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11013 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11015 Variadic C functions now count arguments with ptrdiff_t.
11016 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11017 Back then I didn't know that the Emacs coding style prefers signed int.
11018 Also, in the meantime I found a few more instances where arguments
11019 were being counted with int, which may truncate counts on 64-bit
11020 machines, or EMACS_INT, which may be unnecessarily wide.
11021 * lisp.h (struct Lisp_Subr.function.aMANY)
11022 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11023 Arg counts are now ptrdiff_t, not size_t.
11024 All variadic functions and their callers changed accordingly.
11025 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11026 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11027 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11028 * callint.c (Fcall_interactively): Check arg count for overflow,
11029 to avoid potential buffer overrun. Use signed char, not 'int',
11030 for 'varies' array, so that we needn't bother to check its size
11031 calculation for overflow.
11032 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11033 * eval.c (apply_lambda):
11034 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11035 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11036 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11038 * callint.c (Fcall_interactively): Don't use index var as event count.
11040 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11041 * mem-limits.h (SIZE): Remove; no longer used.
11043 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11045 Remove unnecessary casts.
11046 * xterm.c (x_term_init):
11047 * xfns.c (x_set_border_pixel):
11048 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11049 These aren't needed now that we assume ANSI C.
11051 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11052 It's more likely to cause problems (due to unsigned overflow)
11055 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11057 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11059 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11061 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11063 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11065 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11067 GLYPH_CODE_FACE returns EMACS_INT, not int.
11068 * dispextern.h (merge_faces):
11069 * xfaces.c (merge_faces):
11070 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11071 Don't assume EMACS_INT fits in int.
11073 * character.h (CHAR_VALID_P): Remove unused parameter.
11074 * fontset.c, lisp.h, xdisp.c: All uses changed.
11076 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11078 * fns.c (concat): Minor tuning based on overflow analysis.
11079 This doesn't fix any bugs. Use int to hold character, instead
11080 of constantly refetching from Emacs object. Use XFASTINT, not
11081 XINT, for value known to be a character. Don't bother comparing
11082 a single byte to 0400, as it's always less.
11084 * floatfns.c (Fexpt):
11085 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11087 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11090 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11092 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11093 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11094 incorrectly succeed when S was a string, because 4294967386 was
11095 truncated before it was used.
11097 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11098 Otherwise, an out-of-range integer could cause undefined behavior
11101 * composite.c: Use int, not EMACS_INT, for characters.
11102 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11103 EMACS_INT, for values that are known to be in character range.
11104 This doesn't fix any bugs but is the usual style inside Emacs and
11105 may generate better code on 32-bit machines.
11107 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11108 This is for reasons similar to the recent CHAR_STRING fix.
11109 * charset.c (Fencode_char): Check that character arg is actually
11110 a character. Pass an int to ENCODE_CHAR.
11111 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11112 wider than 'int', as a compile-time check to prevent future regressions
11115 * character.c (char_string): Remove unnecessary casts.
11117 Make sure a 64-bit char is never passed to CHAR_STRING.
11118 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11119 by silently ignoring the top 32 bits, allowing some values
11120 that were far too large to be valid characters.
11121 * character.h: Include <verify.h>.
11122 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11123 arguments are no wider than unsigned, as a compile-time check
11124 to prevent future regressions in this area.
11126 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11127 (Fsubst_char_in_region):
11129 * xdisp.c (decode_mode_spec_coding):
11130 Adjust to CHAR_STRING's new requirement.
11131 * editfns.c (Finsert_char, Fsubst_char_in_region):
11132 * fns.c (concat): Check that character args are actually
11133 characters. Without this test, these functions did the wrong
11134 thing with wildly out-of-range values on 64-bit hosts.
11136 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11137 These casts should not be needed on 32-bit hosts, either.
11138 * keyboard.c (read_char):
11139 * lread.c (Fload): Remove casts to unsigned.
11141 * lisp.h (UNSIGNED_CMP): New macro.
11142 This fixes comparison bugs on 64-bit hosts.
11143 (ASCII_CHAR_P): Use it.
11144 * casefiddle.c (casify_object):
11145 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11146 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11147 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11148 * dispextern.h (FACE_FROM_ID):
11149 * keyboard.c (read_char): Use UNSIGNED_CMP.
11151 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11152 not to EMACS_INT, to avoid GCC warning.
11154 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11156 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11157 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11158 isn't needed on 32-bit machines.
11160 * buffer.c (Fgenerate_new_buffer_name):
11161 Use EMACS_INT for count, not int.
11162 (advance_to_char_boundary): Return EMACS_INT, not int.
11164 * data.c (Qcompiled_function): Now static.
11166 * window.c (window_body_lines): Now static.
11168 * image.c (gif_load): Rename local to avoid shadowing.
11170 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11171 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11172 * alloc.c (make_save_value): Integer argument is now of type
11173 ptrdiff_t, not int.
11174 (mark_object): Use ptrdiff_t, not int.
11175 * lisp.h (pD): New macro.
11176 * print.c (print_object): Use it.
11178 * alloc.c: Use EMACS_INT, not int, to count objects.
11179 (total_conses, total_markers, total_symbols, total_vector_size)
11180 (total_free_conses, total_free_markers, total_free_symbols)
11181 (total_free_floats, total_floats, total_free_intervals)
11182 (total_intervals, total_strings, total_free_strings):
11183 Now EMACS_INT, not int. All uses changed.
11184 (Fgarbage_collect): Compute overall total using a double, so that
11185 integer overflow is less likely to be a problem. Check for overflow
11186 when converting back to an integer.
11187 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11188 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11189 These were 'int' variables that could overflow on 64-bit hosts;
11190 they were never used, so remove them instead of repairing them.
11191 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11192 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
11193 Previously, this ceilinged at INT_MAX, but that doesn't work on
11195 (allocate_pseudovector): Don't use EMACS_INT when int would do.
11197 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
11198 (allocate_vectorlike): Check for ptrdiff_t overflow.
11199 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
11200 when a (possibly-narrower) signed value would do just as well.
11201 We prefer using signed arithmetic, to avoid comparison confusion.
11203 * alloc.c: Catch some string size overflows that we were missing.
11204 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
11205 for convenience in STRING_BYTES_MAX.
11206 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11207 The definition here is exact; the one in lisp.h was approximate.
11208 (allocate_string_data): Check for string overflow. This catches
11209 some instances we weren't catching before. Also, it catches
11210 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11211 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11212 and ptrdiff_t and EMACS_INT are both 64 bits.
11214 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11215 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
11216 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
11218 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
11220 * alloc.c (Fmake_string): Check for out-of-range init.
11222 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
11224 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
11226 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
11228 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
11229 xg_get_default_scrollbar_width.
11231 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
11232 (int_gtk_range_get_value): Move to the scroll bar part of the file.
11233 (style_changed_cb): Call update_theme_scrollbar_width and call
11234 x_set_scroll_bar_default_width and xg_frame_set_char_size for
11235 all frames (Bug#8505).
11236 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
11237 Call gtk_window_set_resizable if HAVE_GTK3.
11238 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
11239 and height if HAVE_GTK3 (Bug#8505).
11240 (scroll_bar_width_for_theme): New variable.
11241 (update_theme_scrollbar_width): New function.
11242 (xg_get_default_scrollbar_width): Move code to
11243 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
11244 (xg_initialize): Call update_theme_scrollbar_width.
11246 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
11248 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
11250 2011-06-12 Martin Rudalics <rudalics@gmx.at>
11252 * frame.c (make_frame): Call other_buffer_safely instead of
11255 * window.c (temp_output_buffer_show): Call display_buffer with
11256 second argument Vtemp_buffer_show_specifiers and reset latter
11257 immediately after the call.
11258 (Vtemp_buffer_show_specifiers): New variable.
11259 (auto_window_vscroll_p, next_screen_context_lines)
11260 (Vscroll_preserve_screen_position): Remove leading asterisks from
11263 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
11265 Fix minor problems found by GCC 4.6.0 static checking.
11266 * buffer.c (Qclone_number): Remove for now, as it's unused.
11267 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
11268 (record_buffer): Remove unused local.
11269 * frame.c (other_visible_frames, frame_buffer_list): Now static.
11270 (set_frame_buffer_list): Remove; unused.
11271 * frame.h (other_visible_frames): Remove decl.
11272 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
11273 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
11274 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
11276 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
11277 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
11278 Define only if HAVE_GPM.
11279 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
11280 (update_hints_inhibit): Remove; never set. All uses removed.
11281 * widgetprv.h (emacsFrameClassRec): Remove decl.
11282 * window.c (delete_deletable_window): Now returns void, since it
11283 wasn't returning anything.
11284 (compare_window_configurations): Remove unused locals.
11285 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
11286 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
11287 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
11288 the same widths as pointers. This follows up on the 2011-05-06 patch.
11289 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
11290 * xterm.h: Likewise.
11291 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
11293 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
11295 * makefile.w32-in: Update dependencies.
11296 (LISP_H): Add lib/intprops.h.
11298 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
11300 * image.c (gif_load): Add animation frame delay to the metadata.
11301 (syms_of_image): Use DEFSYM. New symbol `delay'.
11303 2011-06-11 Martin Rudalics <rudalics@gmx.at>
11305 * window.c (delete_deletable_window): Re-add.
11306 (Fset_window_configuration): Rewrite to handle dead buffers and
11307 consequently deletable windows.
11308 (window_tree, Fwindow_tree): Remove. Supply functionality in
11310 (compare_window_configurations): Simplify code.
11312 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
11314 * image.c (imagemagick_load_image): Fix type mismatch.
11315 (Fimagemagick_types): Likewise.
11317 * window.h (replace_buffer_in_windows): Declare.
11319 2011-06-11 Martin Rudalics <rudalics@gmx.at>
11321 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
11322 Qclone_number. Remove external declaration of Qdelete_window.
11323 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
11325 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
11326 Run Qbuffer_list_update_hook if allowed.
11327 (Fother_buffer): Rewrite doc-string. Major rewrite for new
11328 buffer list implementation.
11329 (other_buffer_safely): New function.
11330 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
11331 calls to replace_buffer_in_windows and

11783 Support character positions inside a run of characters covered by a
11785 (bidi_paragraph_init, bidi_resolve_explicit_1)
11786 (bidi_level_of_next_char): Call bidi_fetch_char and
11787 bidi_fetch_char_advance instead of FETCH_CHAR and
11788 FETCH_CHAR_ADVANCE.
11789 (bidi_init_it): Initialize new members.
11790 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
11792 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11793 instead of using explicit *_CHAR codes.
11794 (bidi_resolve_explicit, bidi_resolve_weak):
11795 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11796 bidirectional text is supported only in multibyte buffers.
11797 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11798 it to initialize the frame_window_p member of struct bidi_it.
11799 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
11800 (bidi_resolve_explicit, bidi_resolve_weak)
11801 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
11802 bidi_it->nchars is non-positive.
11803 (bidi_level_of_next_char): Don't try to lookup the cache for the
11804 next/previous character if nothing is cached there yet, or if we
11805 were just reseat()'ed to a new position.
11807 * xdisp.c (set_cursor_from_row): Set start and stop points
11808 according to the row's direction when priming the loop that looks
11809 for the glyph on which to display cursor.
11810 (single_display_spec_intangible_p): Function deleted.
11811 (display_prop_intangible_p): Reimplement to call
11812 handle_display_spec instead of single_display_spec_intangible_p.
11813 Accept 3 additional arguments needed by handle_display_spec.
11814 This fixes incorrect cursor motion across display property with complex
11815 values: lists, `(when COND...)' forms, etc.
11816 (single_display_spec_string_p): Support property values that are
11817 lists with the argument STRING its top-level element.
11818 (display_prop_string_p): Fix the condition for processing a
11819 property that is a list to be consistent with handle_display_spec.
11820 (handle_display_spec): New function, refactored from the
11821 last portion of handle_display_prop.
11822 (compute_display_string_pos): Accept additional argument
11823 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11824 value of a `display' property is a "replacing spec".
11825 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11826 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11827 the display property, but just return a value indicating whether
11828 the display property will replace the characters it covers.
11829 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11830 frame_window_p members of struct bidi_it.
11831 (compute_display_string_pos, compute_display_string_end):
11833 (push_it): Accept second argument POSITION, where pop_it should
11834 jump to continue iteration.
11835 (reseat_1): Initialize bidi_it.disp_pos.
11837 * keyboard.c (adjust_point_for_property): Adjust the call to
11838 display_prop_intangible_p to its new signature.
11840 * dispextern.h (struct bidi_it): New member frame_window_p.
11841 (bidi_init_it): Update prototypes.
11842 (display_prop_intangible_p): Update prototype.
11843 (compute_display_string_pos, compute_display_string_end):
11844 Declare prototypes.

11850 Malloc failure behavior now depends on size of allocation.
11851 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
11852 * lisp.h: Change signatures accordingly.
11853 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
11854 All callers changed. (Bug#8762)
11856 * gnutls.c: Use Emacs's memory allocators.
11857 Without this change, the gnutls library would invoke malloc etc.
11858 directly, which causes problems on non-SYNC_INPUT hosts, and which
11859 runs afoul of improving memory_full behavior. (Bug#8761)
11860 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11861 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11862 xfree instead of the default malloc, realloc, free.
11863 (Fgnutls_boot): No need to check for memory allocation failure,
11864 since xmalloc does that for us.
11866 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11867 * category.c (hash_get_category_set):
11868 * ccl.c (ccl_driver):

11882 * image.c (make_image, search_image_cache, lookup_image)
11883 (xpm_put_color_table_h):
11884 * lisp.h (struct Lisp_Hash_Table):
11885 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11886 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11887 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11888 * alloc.c (allocate_vectorlike):
11889 Check for overflow in vector size calculations.
11890 * ccl.c (ccl_driver):
11891 Check for overflow when converting EMACS_INT to int.
11892 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11893 need to be updated by these changes.
11894 * fns.c (make_hash_table, maybe_resize_hash_table):
11895 Check for integer overflow with large hash tables.
11896 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11897 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11898 (SXHASH_REDUCE): New macro.
11899 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11900 Use it instead of discarding useful hash info with large hash values.
11901 (sxhash_float): New function.
11902 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11903 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11904 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11905 Rewrite to use FIXNUM_BITS, as this simplifies things.
11906 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11907 Adjust signatures to match updated version of code.
11908 (consing_since_gc): Now EMACS_INT, since a single hash table can
11909 use more than INT_MAX bytes.
11911 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11913 Make it possible to build with GCC-4.6+ -O2 -flto.
11915 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
11917 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
11919 * minibuf.c (get_minibuffer, read_minibuf_unwind):
11920 Call minibuffer-inactive-mode.
11922 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11924 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11925 Update dependencies.
11927 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11929 * data.c (init_data): Remove code for UTS, this system is not
11932 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11934 Don't force ./temacs to start in terminal mode.
11936 * frame.c (make_initial_frame): Initialize faces in all cases, not
11937 only when CANNOT_DUMP is defined.
11938 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11940 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11942 * dispnew.c (add_window_display_history): Use const for the string
11943 pointer. Remove declaration, not needed.
11945 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11947 Use 'inline', not 'INLINE'.
11948 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11949 * alloc.c, fontset.c (INLINE): Remove.
11950 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11951 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11952 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11953 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11954 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11956 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11958 Make it possible to run ./temacs.
11960 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11961 syms_of_callproc does the same thing. Remove test for
11962 "initialized", do it in the caller.
11963 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11965 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11967 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11968 (read_minibuf): Use get_minibuffer.
11969 (syms_of_minibuf): Use DEFSYM.
11970 (Qmetadata): New var.
11971 * data.c (Qbuffer): Don't make it static.
11972 (syms_of_data): Use DEFSYM.
11974 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11976 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11977 (CCL_CODE_MIN): New macro.
11979 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11981 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11983 * eval.c (Qdebug): Now static.
11984 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11985 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11986 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11988 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11990 * image.c: Various fixes to ImageMagick code comments.
11991 (Fimagemagick_types): Doc fix.
11993 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11995 Minor fixes prompted by GCC 4.6.0 warnings.
11997 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11999 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12000 (x_clipboard_manager_save_all): Move extern decl to ...
12001 * xterm.h: ... here, so that it can be checked for consistency.
12003 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12005 * xselect.c (x_clipboard_manager_save_frame)
12006 (x_clipboard_manager_save_all): New functions.
12007 (Fx_clipboard_manager_save): Lisp function deleted.
12009 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12010 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12012 * xterm.h: Update prototype.
12014 2011-05-28 William Xu <william.xwl@gmail.com>
12016 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12017 exiting (Bug#8239).
12019 2011-05-28 Jim Meyering <meyering@redhat.com>
12021 Avoid a sign-extension bug in crypto_hash_function.
12022 * fns.c (to_uchar): Define.
12023 (crypto_hash_function): Use it to convert some newly-signed
12024 variables to unsigned, to avoid sign-extension bugs. For example,
12025 without this change, (md5 "truc") would evaluate to
12026 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12027 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12028 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12030 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12032 Integer overflow fixes.
12034 * dbusbind.c: Serial number integer overflow fixes.
12035 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12036 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12037 to hold a serial number that is too large for a fixnum.
12038 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12039 Check for serial numbers out of range. Decode any serial number
12040 that was so large that it became a float. (Bug#8722)
12042 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12043 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12044 Use XFASTINT rather than XUINT when numbers are nonnegative.
12045 (xd_append_arg, Fdbus_method_return_internal):
12046 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12047 arguments, check that Lisp number is nonnegative, rather than
12048 silently wrapping negative numbers around. (Bug#8722)
12049 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12052 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12054 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12056 ccl: Add integer overflow checks.
12057 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12058 (IN_INT_RANGE): New macros.
12059 (ccl_driver): Use them to check for integer overflow when
12060 decoding a CCL program. Many of the new checks are whether XINT (x)
12061 fits in int; it doesn't always, on 64-bit hosts. The new version
12062 doesn't catch all possible integer overflows, but it's an
12063 improvement. (Bug#8719)
12065 * alloc.c (make_event_array): Use XINT, not XUINT.
12066 There's no need for unsigned here.
12068 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12069 This follows up to the 2011-05-06 change that substituted uintptr_t
12070 for EMACS_INT. This case wasn't caught back then.
12072 Rework Fformat to avoid integer overflow issues.
12073 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12074 now (part of C89). Include <verify.h>.
12075 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12076 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12077 (Fformat): Avoid the prepass trying to compute sizes; it was only
12078 approximate and thus did not catch overflow reliably. Instead, walk
12079 through the format just once, formatting and computing sizes as we go,
12080 checking for integer overflow at every step, and allocating a larger
12081 buffer as needed. Keep track separately whether the format is
12082 multibyte. Keep only the most-recently calculated precision, rather
12083 than them all. Record whether each argument has been converted to
12084 string. Use EMACS_INT, not int, for byte and char and arg counts.
12085 Support field widths and precisions larger than INT_MAX. Avoid
12086 sprintf's undefined behavior with conversion specifications such as %#d
12087 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12088 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12089 formatting out-of-range floating point numbers with int
12090 formats. (Bug#8668)
12092 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12094 * data.c: Avoid integer truncation in expressions involving floats.
12095 * data.c: Include <intprops.h>.
12096 (arith_driver): When there's an integer overflow in an expression
12097 involving floating point, convert the integers to floating point
12098 so that the resulting value does not suffer from catastrophic
12099 integer truncation. For example, on a 64-bit host (* 4
12100 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12101 Do not rely on undefined behavior after integer overflow.
12103 merge count_size_as_multibyte, parse_str_to_multibyte
12104 * character.c, character.h (count_size_as_multibyte):
12105 Rename from parse_str_to_multibyte; all uses changed.
12106 Check for integer overflow.
12107 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12108 since it's now a duplicate of the other. This is more of
12109 a character than a buffer op, so better that it's in character.c.
12110 * fns.c, print.c: Adjust to above changes.
12112 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12114 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12116 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12118 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12119 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12120 (x_clipboard_manager_save): Now static.
12121 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12123 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12124 (crypto_hash_function): Now static.
12125 Fix pointer signedness problems. Avoid unnecessary initializations.
12127 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12129 * termhooks.h (Vselection_alist): Make it terminal-local.
12131 * terminal.c (create_terminal): Initialize it.
12133 * xselect.c: Support for clipboard managers.
12134 (Vselection_alist): Move to termhooks.h as terminal-local var.
12135 (LOCAL_SELECTION): New macro.
12136 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12137 (symbol_to_x_atom): Remove gratuitous arg.
12138 (x_handle_selection_request, lisp_data_to_selection_data)
12139 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12140 (x_own_selection, x_get_local_selection, x_convert_selection):
12141 New arg, specifying work frame. Use terminal-local Vselection_alist.
12142 (some_frame_on_display): Delete unused function.
12143 (Fx_own_selection_internal, Fx_get_selection_internal)
12144 (Fx_disown_selection_internal, Fx_selection_owner_p)
12145 (Fx_selection_exists_p): New optional frame arg.
12146 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12147 (x_handle_selection_clear): Don't treat other terminals with the
12148 same keyboard specially. Use the terminal-local Vselection_alist.
12149 (x_clear_frame_selections): Use Frun_hook_with_args.
12151 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12153 * xterm.h: Add support for those atoms.
12155 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12157 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12158 (converted_selections, conversion_fail_tag): New global variables.
12159 (x_selection_request_lisp_error): Free the above.
12160 (x_get_local_selection): Remove unnecessary code.
12161 (x_reply_selection_request): Args changed; handle arbitrary array
12162 of converted selections stored in converted_selections.
12163 Separate the XChangeProperty and SelectionNotify steps.
12164 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12165 (x_convert_selection): New function.
12166 (x_handle_selection_event): Simplify.
12167 (x_get_foreign_selection): Don't ignore incoming requests while
12168 waiting for an answer; this will fail when we implement
12169 SAVE_TARGETS, and seems unnecessary anyway.
12170 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12171 (Vx_sent_selection_functions): Doc fix.
12173 2011-05-26 Leo Liu <sdl.web@gmail.com>
12175 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12177 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12179 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12181 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12182 for fringe update if it has periodic bitmap.
12183 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12184 and fringe_bitmap_periodic_p.
12186 * fringe.c (get_fringe_bitmap_data): New function.
12187 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12188 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12189 row. Mark glyph row for fringe update if periodicity changed.
12191 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12192 for fringe update unless it has periodic bitmap.
12194 2011-05-25 Kenichi Handa <handa@m17n.org>
12196 * xdisp.c (get_next_display_element): Set correct it->face_id for
12197 a static composition.
12199 2011-05-24 Leo Liu <sdl.web@gmail.com>

12204 * fns.c (crypto_hash_function, Fsha1): New function.
12205 (Fmd5): Use crypto_hash_function.
12206 (syms_of_fns): Add Ssha1.
12208 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12210 * gnutls.c: Remove unused macros.
12211 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12212 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12213 Remove macros that are defined and never used.
12214 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12216 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12218 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12219 (Fx_get_selection_internal): Minor cleanup.
12220 (Fx_own_selection_internal): Rename arguments for consistency with
12223 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12225 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12227 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12229 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12231 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12233 * dispnew.c (scrolling_window): Don't exclude the case that the
12234 last enabled row in the desired matrix touches the bottom boundary.
12236 2011-05-21 Glenn Morris <rgm@gnu.org>
12238 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12239 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12240 and add some more files.
12242 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12244 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12245 report_file_error introduced by the change from 2011-05-07.
12247 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12249 * systime.h (Time): Define only if emacs is defined.
12250 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12251 where the include path doesn't have X11/X.h by default. See
12252 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12254 2011-05-20 Kenichi Handa <handa@m17n.org>
12256 * composite.c (find_automatic_composition): Fix previous change.
12258 2011-05-20 Glenn Morris <rgm@gnu.org>
12260 * lisp.mk: New file, split from Makefile.in.
12261 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12262 (shortlisp): Remove.
12263 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12265 2011-05-19 Glenn Morris <rgm@gnu.org>
12267 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12268 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12269 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12270 (lisp): Set the order to that of loadup.el.
12271 (shortlisp): Make it a copy of $lisp.
12272 (SOME_MACHINE_LISP): Remove.
12273 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12274 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12276 2011-05-18 Kenichi Handa <handa@m17n.org>
12278 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12279 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12280 (find_automatic_composition): Mostly rewrite for efficiency.
12282 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12284 * makefile.w32-in: Update dependencies.
12286 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12288 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12289 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12291 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12293 Fix some integer overflow issues, such as string length overflow.
12295 * insdel.c (count_size_as_multibyte): Check for string overflow.
12297 * character.c (lisp_string_width): Check for string overflow.
12298 Use EMACS_INT, not int, for string indexes and lengths; in
12299 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12300 the resulting string length overflows an EMACS_INT; instead,
12301 report a string overflow if no precision given. When checking for
12302 precision exhaustion, use a check that cannot possibly have
12303 integer overflow. (Bug#8675)
12304 * character.h (lisp_string_width): Adjust to new signature.
12306 * alloc.c (string_overflow): New function.
12307 (Fmake_string): Use it. This doesn't change behavior, but saves
12308 a few bytes and will simplify future changes.
12309 * character.c (string_escape_byte8): Likewise.
12310 * lisp.h (string_overflow): New decl.
12312 Fixups, following up to the user-interface timestamp change.
12313 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12314 for UI timestamps, instead of unsigned long.
12315 * msdos.c (mouse_get_pos): Likewise.
12316 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12317 * w32gui.h (Time): Define by including "systime.h" rather than by
12318 declaring it ourselves. (Bug#8664)
12320 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12321 * image.c (clear_image_cache): Likewise.
12323 * term.c (term_mouse_position): Don't assume time_t wraparound.
12325 Be more systematic about user-interface timestamps.
12326 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12327 and sometimes 'EMACS_UINT', to represent these timestamps.
12328 This change causes it to use 'Time' uniformly, as that's what X uses.
12329 This makes the code easier to follow, and makes it easier to catch
12330 integer overflow bugs such as Bug#8664.
12331 * frame.c (Fmouse_position, Fmouse_pixel_position):
12332 Use Time, not unsigned long, for user-interface timestamps.
12333 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12334 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12335 * keyboard.h (last_event_timestamp): Likewise.
12336 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12337 * menu.h (xmenu_show): Likewise.
12338 * term.c (term_mouse_position): Likewise.
12339 * termhooks.h (struct input_event.timestamp): Likewise.
12340 (struct terminal.mouse_position_hook): Likewise.
12341 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12342 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12343 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12344 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12345 what it was before.
12346 * menu.h, termhooks.h: Include "systime.h", for Time.
12348 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12349 Don't assume that the difference between two unsigned long values
12350 can fit into an integer. At this point, we know button_down_time
12351 <= event->timestamp, so the difference must be nonnegative, so
12352 there's no need to cast the result if double-click-time is
12353 nonnegative, as it should be; check that it's nonnegative, just in
12354 case. This bug is triggered when events are more than 2**31 ms
12355 apart (about 25 days). (Bug#8664)
12357 * xselect.c (last_event_timestamp): Remove duplicate decl.
12358 (x_own_selection): Remove needless cast to unsigned long.
12360 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12361 that always fit in int. Use a sentinel instead of a counter, to
12362 avoid a temp and to allay GCC's concerns about possible int overflow.
12363 * frame.h (struct frame): Use int for menu_bar_items_used
12364 instead of EMACS_INT, since it always fits in int.
12366 * menu.c (grow_menu_items): Check for int overflow.
12368 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12370 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12371 Before, the code was not consistent. These values cannot exceed
12372 2**31 - 1 so there's no need to make them unsigned.
12373 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12374 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12375 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12377 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12379 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12380 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12381 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12382 presumably because the widths might not match.
12384 * window.c (size_window): Avoid needless test at loop start.
12386 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12388 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12390 2011-05-12 Drew Adams <drew.adams@oracle.com>
12392 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12394 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12396 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12397 `width' to `bar_area_x' and `bar_area_width', respectively.
12398 (x_scroll_run): Take account of fringe background extension.
12400 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12401 Rename local vars `left' and `width' to `bar_area_x' and
12402 `bar_area_width', respectively.
12403 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12404 background extension.
12406 2011-05-10 Jim Meyering <meyering@redhat.com>
12408 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12410 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12412 * image.c (Finit_image_library): Return t for built-in image types,
12413 like pbm and xbm. (Bug#8640)
12415 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12417 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12419 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12421 * w32console.c (Fset_screen_color): Doc fix.
12422 (Fget_screen_color): New function.
12423 (syms_of_ntterm): Defsubr it.
12425 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12426 unlink the temporary file if Fcall_process didn't create it in the
12428 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12429 child process will be redirected to a file specified with `:file'.
12430 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12431 cue to call_process_cleanup not to close that handle.
12433 2011-05-07 Ben Key <bkey76@gmail.com>
12435 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12436 one of two shell specific rules, either bootstrap-temacs-CMD or
12437 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12438 to the previous implementation of the bootstrap-temacs rule.
12439 The bootstrap-temacs-CMD rule is similar to the previous
12440 implementation of the bootstrap-temacs rule except that it
12441 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12444 These changes, along with some changes to nt/configure.bat,
12445 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12446 earlier fix to add support for --cflags and --ldflags options
12447 that include quotes so that it works whether make uses cmd or
12450 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12452 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12453 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12455 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12456 a string. Handle both cases.
12457 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12458 (Fdbus_register_method): Use Qinvalid_function.
12460 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12462 * makefile.w32-in: Update dependencies.
12463 (LISP_H): Add inttypes.h and stdin.h.
12464 (PROCESS_H): Add unistd.h.
12466 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12468 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12469 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12471 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12473 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12475 * term.c (vfatal): Remove stray call to va_end.
12476 It's not needed and the C Standard doesn't allow it here anyway.
12478 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12479 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12481 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12484 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12486 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12488 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12490 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12492 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12494 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12495 * charset.c (Fdefine_charset_internal): Don't initialize
12496 charset.code_space[15]. The value was garbage, on hosts with
12497 32-bit int (Bug#8600).
12499 * lread.c (read_integer): Be more consistent with string-to-number.
12500 Use string_to_number to do the actual conversion; this avoids
12501 rounding errors and fixes some other screwups. Without this fix,
12502 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12503 (digit_to_number): Move earlier, for benefit of read_integer.
12504 Return -1 if the digit is out of range for the base, -2 if it is
12505 not a digit in any supported base. (Bug#8602)
12507 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12509 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12510 to match comment at start of function. This also removes a
12511 GCC warning about overflow in a 32+64-bit port.
12513 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12515 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12516 Reported by Stefan Monnier in
12517 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12518 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12519 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12521 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12522 (EMACS_UINTPTR): Likewise, with uintptr_t.
12524 * lisp.h: Prefer 64-bit EMACS_INT if available.
12525 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12526 on 32-bit hosts that have 64-bit int, so that they can access
12528 However, temporarily disable this change unless the temporary
12529 symbol WIDE_EMACS_INT is defined.
12531 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12533 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12534 This removes an assumption that EMACS_INT and long are the same
12535 width as pointers. The assumption is true for Emacs porting targets
12536 now, but we want to make other targets possible.
12537 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12538 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12539 In the rest of the code, change types of integers that hold casted
12540 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12541 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12542 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12543 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12544 No need to cast type when ORing.
12545 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12546 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12547 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12548 assume EMACS_INT is the same width as char *.
12549 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12550 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12551 Remove no-longer-needed casts.
12552 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12553 (xg_tool_bar_help_callback, xg_make_tool_item):
12554 Use EMACS_INTPTR to hold an integer
12555 that will be cast to void *; this can avoid a GCC warning
12556 if EMACS_INT is not the same width as void *.
12557 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12558 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12559 (current_message_1, set_message_1):
12560 Use a local to convert to proper width without a cast.
12561 * xmenu.c (dialog_selection_callback): Likewise.
12563 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12564 Also, don't assume VALBITS / RAND_BITS is less than 5,
12565 and don't rely on undefined behavior when shifting a 1 left into
12567 * lisp.h (get_random): Change signature to match.
12569 * lread.c (hash_string): Use size_t, not int, for hash computation.
12570 Normally we prefer signed values; but hashing is special, because
12571 it's better to use unsigned division on hash table sizes so that
12572 the remainder is nonnegative. Also, size_t is the natural width
12573 for hashing into memory. The previous code used 'int', which doesn't
12574 retain enough info to hash well into very large tables.
12575 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12577 * dbusbind.c: Don't possibly lose pointer info when converting.
12578 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12579 Use XPNTR rather than XHASH, so that the high-order bits of
12580 the pointer aren't lost when converting through void *.
12582 * eval.c (Fautoload): Don't double-shift a pointer.
12584 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12586 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12588 * gnutls.c (DEF_GNUTLS_FN):
12589 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12591 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12593 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12596 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12598 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12599 New version that can reserve upto 2GB of heap space.
12601 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12603 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12605 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12607 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12608 `gnutls_certificate_set_x509_key_file'.
12610 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12612 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12613 Update dependencies.
12615 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12617 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12618 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12619 Remove unused parameter `fildes'.
12620 * process.c (read_process_output, send_process): Don't pass it.
12622 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12624 Fix previous change: the library cache is defined in w32.c.
12625 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12626 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12628 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12630 Implement dynamic loading of GnuTLS on Windows.
12632 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12633 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12634 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):

12664 Initialize and staticpro them.
12665 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12667 * process.c: Include lisp.h before w32.h, not after.
12668 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12669 instead of gnutls_record_check_pending.
12671 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12673 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12675 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12676 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12679 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12681 * xterm.c (x_set_frame_alpha): Do not set property on anything

12718 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12720 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12721 rather than `XVECTOR (FOO)->size'.
12723 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12724 inttypes.h, as a gnulib replacement is used if it not available in
12727 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12729 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12730 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12731 of MOST_POSITIVE_FIXNUM. (Bug#8528)

12734 will grow beyond MOST_POSITIVE_FIXNUM.
12735 (decode_coding_emacs_mule): Abort if there isn't enough place in

12737 space for up to 2 characters produced in a loop.
12738 (decode_coding_iso_2022): Abort if there isn't enough place in
12739 charbuf for the composition carryover bytes.
12741 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12743 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12744 aborting when %lld or %lll format is passed.
12745 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12746 %llo or %llx format is passed. (Bug#8545)
12748 * window.c (window_scroll_line_based): Use a marker instead of
12749 simple variables to record original value of point. (Bug#7952)
12751 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12752 produced by %s or %c overflows available buffer space. (Bug#8545)
12754 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12756 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12757 (SIZE_MAX): Move defn after all includes, as they might #define it.
12759 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12761 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12763 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12765 * keyboard.c (Qdelayed_warnings_hook): Define.
12766 (command_loop_1): Run `delayed-warnings-hook'
12767 if Vdelayed_warnings_list is non-nil.
12768 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12769 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12771 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12773 * doprnt.c (doprnt): Don't return value smaller than the buffer
12774 size if the message was truncated. (Bug#8545).
12776 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12778 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12779 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12781 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12783 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12785 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12787 * makefile.w32-in: Update dependencies.
12789 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12791 Improve `doprnt' and its usage. (Bug#8545)
12792 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12793 `format_end'. Remove support for %l as a conversion specifier.
12794 Don't use xrealloc. Improve diagnostics when the %l size modifier
12795 is used. Update the commentary.
12797 * eval.c (verror): Simplify calculation of size_t.
12799 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12802 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12804 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12807 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12809 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12810 This makes this file independent of the recent pseudovector change.
12812 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12814 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12816 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12817 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12818 Remove unused local.
12819 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12821 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12822 GCC 4.6.0 optimizes based on type-based alias analysis.
12823 For example, if b is of type struct buffer * and v of type struct
12824 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12825 != &v->size, and therefore "v->size = 1; b->size = 2; return
12826 v->size;" must therefore return 1. This assumption is incorrect
12827 for Emacs, since it type-puns struct Lisp_Vector * with many other
12828 types. To fix this problem, this patch adds a new type struct
12829 vectorlike_header that documents the constraints on layout of vectors
12830 and pseudovectors, and helps optimizing compilers not get fooled
12831 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12832 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12833 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12835 (XSETPVECTYPE): Rewrite in terms of new macro.
12836 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12837 This is a bit clearer, and further avoids the possibility of
12838 undesirable aliasing.
12839 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12840 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12841 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12842 since Lisp_Subr is a special case (no "next" field).
12843 (ASIZE): Now uses header.size rather than size.
12844 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12845 to avoid the hassle of writing XVECTOR (foo)->header.size.
12846 (struct vectorlike_header): New type.
12847 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12848 object, to help avoid aliasing.
12849 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12850 (SUBRP): Likewise, since Lisp_Subr is a special case.
12851 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12852 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12853 (struct Lisp_Hash_Table): Combine first two members into a single
12854 struct vectorlike_header member. All uses of "size" and "next" members
12855 changed to be "header.size" and "header.next".
12856 * buffer.h (struct buffer): Likewise.
12857 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12858 * frame.h (struct frame): Likewise.
12859 * process.h (struct Lisp_Process): Likewise.
12860 * termhooks.h (struct terminal): Likewise.
12861 * window.c (struct save_window_data, struct saved_window): Likewise.
12862 * window.h (struct window): Likewise.
12863 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12864 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12865 * buffer.c (init_buffer_once): Likewise.
12866 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12868 * process.c (Fformat_network_address): Use local var for size,
12871 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12873 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12874 * data.c (atof): Remove decl; no longer used or needed.
12875 (digit_to_number): Move to lread.c.
12876 (Fstring_to_number): Use new string_to_number function, to be
12877 consistent with how the Lisp reader treats infinities and NaNs.
12878 Do not assume that floating-point numbers represent EMACS_INT
12879 without losing information; this is not true on most 64-bit hosts.
12880 Avoid double-rounding errors, by insisting on integers when
12881 parsing non-base-10 numbers, as the documentation specifies.
12882 * lisp.h (string_to_number): New decl, replacing ...
12883 (isfloat_string): Remove.
12884 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12885 (read1): Do not accept +. and -. as integers; this
12886 appears to have been a coding error. Similarly, do not accept
12887 strings like +-1e0 as floating point numbers. Do not report
12888 overflow for integer overflows unless the base is not 10 which
12889 means we have no simple and reliable way to continue.
12890 Break out the floating-point parsing into a new
12891 function string_to_number, so that Fstring_to_number parses
12892 floating point numbers consistently with the Lisp reader.
12893 (digit_to_number): Move here from data.c. Make it static inline.
12894 (E_CHAR, EXP_INT): Remove, replacing with ...
12895 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12896 (string_to_number): New function, replacing isfloat_string.
12897 This function checks for valid syntax and produces the resulting
12898 Lisp float number too. Rework it so that string-to-number
12899 no longer mishandles examples like "1.0e+". Use strtoumax,
12900 so that overflow for non-base-10 numbers is reported only when
12901 there's no portable and simple way to convert to floating point.
12903 * textprop.c (set_text_properties_1): Rewrite for clarity,
12904 and to avoid GCC warning about integer overflow.
12906 * intervals.h (struct interval): Use EMACS_INT for members
12907 where EMACS_UINT might cause problems. See
12908 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12909 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12910 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12912 (offset_intervals): Tell GCC not to worry about length overflow
12913 when negating a negative length.
12915 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12916 (overrun_check_free): Likewise.
12918 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12919 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12922 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12923 (gnutls_make_error): Rename local to avoid shadowing.
12924 (gnutls_emacs_global_deinit): ifdef out; not used.
12925 (Fgnutls_boot): Use const for pointer to readonly storage.
12926 Comment out unused local. Fix pointer signedness problems.
12928 * lread.c (openp): Don't stuff size_t into an 'int'.
12929 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12930 about possible signed overflow.
12932 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12933 (GDK_KEY_g): Don't define if already defined.
12934 (xg_prepare_tooltip): Avoid pointer signedness problem.
12935 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12937 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12938 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12940 * xfns.c (Fx_window_property): Simplify a bit,
12941 to make a bit faster and to avoid GCC 4.6.0 warning.
12942 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12944 * fns.c (internal_equal): Don't assume size_t fits in int.
12946 * alloc.c (compact_small_strings): Tighten assertion a little.
12948 Replace pEd with more-general pI, and fix some printf arg casts.
12949 * lisp.h (pI): New macro, generalizing old pEd macro to other
12950 conversion specifiers. For example, use "...%"pI"d..." rather
12951 than "...%"pEd"...".
12952 (pEd): Remove. All uses replaced with similar uses of pI.
12953 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12954 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12955 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12956 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12957 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12958 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12959 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12961 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12962 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12963 * print.c (safe_debug_print, print_object): Likewise.
12964 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12966 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12967 avoiding the 0 flag, which is not portable.
12968 * process.c (Fmake_network_process): Use pI to avoid cast.
12969 * region-cache.c (pp_cache): Likewise.
12970 * xdisp.c (decode_mode_spec): Likewise.
12971 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12972 behavior on 64-bit hosts with printf arg.
12973 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12974 (x_stop_queuing_selection_requests): Likewise.
12975 (x_get_window_property): Don't truncate byte count to an 'int'
12978 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12979 here, since it parses constructs like leading '-' and spaces,
12980 which are not wanted; and it overflows with large numbers.
12981 Instead, simply match F[0-9]+, which is what is wanted anyway.
12983 * alloc.c: Remove unportable assumptions about struct layout.
12984 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12985 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12986 (allocate_vectorlike, make_pure_vector): Use the new macros,
12987 plus offsetof, to remove unportable assumptions about struct layout.
12988 These assumptions hold on all porting targets that I know of, but
12989 they are not guaranteed, they're easy to remove, and removing them
12990 makes further changes easier.
12992 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12993 This doesn't fix a bug but makes the code clearer.
12994 (string_overrun_cookie): Now const. Use initializers that
12995 don't formally overflow signed char, to avoid warnings.
12996 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12997 can cause Emacs to crash when string overrun checking is enabled.
12998 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12999 multiple of sizeof (EMACS_INT); it need not be, if
13000 alignof(EMACS_INT) < sizeof (EMACS_INT).
13001 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
13003 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
13005 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
13007 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
13009 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
13010 supposed to be handshaking. (Bug#8556)
13011 Reported by Paul Eggert <eggert@cs.ucla.edu>.
13013 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
13015 * lisp.h (Qdebug): List symbol.
13016 * eval.c (Qdebug): Restore global linkage.
13017 * keyboard.c (debug-on-event): New variable.
13018 (handle_user_signal): Break into debugger when debug-on-event
13019 matches the current signal symbol.
13021 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
13023 * alloc.c (check_sblock, check_string_bytes)
13024 (check_string_free_list): Convert to standard C.
13026 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
13028 * w32.c (emacs_gnutls_push): Fix typo.
13030 2011-04-25 Eli Zaretskii <eliz@gnu.org>
13032 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
13033 "cast to pointer from integer of different size".
13035 Improve doprnt and its use in verror. (Bug#8545)
13036 * doprnt.c (doprnt): Document the set of format control sequences
13037 supported by the function. Use SAFE_ALLOCA instead of always
13040 * eval.c (verror): Don't limit the buffer size at size_max-1, that
13041 is one byte too soon. Don't use xrealloc; instead xfree and
13044 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
13046 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
13049 * gnutls.c: Renamed global_initialized to
13050 gnutls_global_initialized. Added internals for the
13051 :verify-hostname-error, :verify-error, and :verify-flags
13052 parameters of `gnutls-boot' and documented those parameters in the
13053 docstring. Start callback support.
13054 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
13055 unless a fatal error occurred. Call gnutls_alert_send_appropriate
13056 on error. Return error code.

13545 * insdel.c: Make symbols static if they're not exported.
13546 However, leave prepare_to_modify_buffer alone. It's never
13547 called from outside this function, but that appears to be a bug.

13583 * fontset.h (face_suitable_for_char_p): Remove decl.
13584 * xfaces.c (face_at_string_position):
13585 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
13586 since 0 is always ASCII.
13588 * fns.c (weak_hash_tables): Now static.

13609 * editfns.c, lisp.h (get_operating_system_release): Remove.

13728 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.

13730 was inaccessible from Lisp.
13731 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13732 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13734 alloc.c: Import and export fewer symbols, and remove unused items.
13735 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13737 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13738 it's not optimized away by whole-program optimization.

13752 * xdisp.c (message_enable_multibyte): Now static.
13754 Declare Lisp_Object Q* variables to be 'static' if not exported.
13755 This makes it easier for human readers (and static analyzers)
13756 to see whether these variables are used from other modules.
13757 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

13768 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13770 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13772 Make Emacs functions such as Fatom 'static' by default.
13773 This makes it easier for human readers (and static analyzers)
13774 to see whether these functions can be called from other modules.
13775 DEFUN now defines a static function. To make the function external
13776 so that it can be used in other C modules, use the new macro DEFUE.
13777 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13778 (Finit_image_library):
13779 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

13782 Remove decls, since these functions are now static.
13783 (Funintern, Fget_internal_run_time): New decls, since these functions
13784 were already external.
13786 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

13793 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13794 Mark functions with DEFUE instead of DEFUN,
13795 if they are used in other modules.
13796 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13797 decls for now-static functions.
13798 * buffer.h (Fdelete_overlay): Remove decl.

13829 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13831 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13834 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13836 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13837 when at ZV. (Bug#8487)
13839 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13841 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13843 * keyboard.c (parse_tool_bar_item): Likewise.
13844 * sound.c (sound_cleanup, alsa_close): Likewise.
13845 * termcap.c (tgetent): Likewise.

13850 (overrun_check_free): Protoize.
13852 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13854 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13855 since callers should never pass a negative size.
13856 Change the signature to match that of plain 'read' and 'write'; see
13857 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13858 * lisp.h: Update prototypes of emacs_write and emacs_read.
13860 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13862 * xdisp.c (redisplay_window): Don't try to determine the character
13863 position of the scroll margin if the window start point w->startp
13864 is outside the buffer's accessible region. (Bug#8468)
13866 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13868 Fix write-region and its subroutines for buffers > 2GB.
13869 * fileio.c (a_write, e_write): Modify declaration of arguments and
13870 local variables to support buffers larger than 2GB.
13871 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13873 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13874 argument, local variables, and return value.
13876 * lisp.h: Update prototypes of emacs_write and emacs_read.
13878 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13880 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13882 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13884 Fix more problems found by GCC 4.6.0's static checks.
13886 * xdisp.c (vmessage): Use a better test for character truncation.
13888 * charset.c (load_charset_map): <, not <=, for optimization,
13889 and to avoid potential problems with integer overflow.
13890 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13891 * casetab.c (set_identity, shuffle): Likewise.
13892 * editfns.c (Fformat): Likewise.
13893 * syntax.c (skip_chars): Likewise.
13895 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13896 This also lets GCC 4.6.0 generate slightly better loop code.
13898 * callint.c (Fcall_interactively): <, not <=, for optimization.
13899 (Fcall_interactively): Count the number of arguments produced,
13900 not the number of arguments given. This is simpler and lets GCC
13901 4.6.0 generate slightly better code.
13903 * ftfont.c: Distingish more carefully between FcChar8 and char.
13904 The previous code passed unsigned char * to a functions like
13905 strlen and xstrcasecmp that expect char *, which does not
13906 conform to the C standard.
13907 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13908 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13909 char * when the C standard requires it.
13911 * keyboard.c (read_char): Remove unused var.
13913 * eval.c: Port to Windows vsnprintf (Bug#8435).
13914 Include <limits.h>.
13915 (SIZE_MAX): Define if the headers do not.
13916 (verror): Do not give up if vsnprintf returns a negative count.
13917 Instead, grow the buffer. This ports to Windows vsnprintf, which
13918 does not conform to C99. Problem reported by Eli Zaretskii.
13919 Also, simplify the allocation scheme, by avoiding the need for
13920 calling realloc, and removing the ALLOCATED variable.
13922 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13924 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13925 But keep the doprint source code for now, as we might revamp it
13926 and use it again (Bug#8435).
13927 * lisp.h (doprnt): Remove.
13928 * Makefile.in (base_obj): Remove doprnt.o.
13929 * deps.mk (doprnt.o): Remove.
13931 error: Print 32- and 64-bit integers portably (Bug#8435).
13932 Without this change, on typical 64-bit hosts error ("...%d...", N)
13933 was used to print both 32- and 64-bit integers N, which relied on
13934 undefined behavior.
13935 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13936 * lisp.h (error, verror): Mark as printf-like functions.
13937 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13938 Report overflow in size calculations when allocating printf buffer.
13939 Do not truncate output string at its first null byte.
13940 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13941 Truncate the output at a character boundary, since vsnprintf does not

13967 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13968 return ssize_t not "int", and use size_t as the buffer length.
13969 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13970 * gnutls.h: Update declarations.

14087 This avoids several warnings with gcc -Wstrict-overflow.
14088 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14089 directly, rather than having caller test rule sign. This avoids
14090 some unnecessary tests.
14091 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14092 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14093 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

14110 since the condition is always true at first.
14112 * intervals.c (graft_intervals_into_buffer): Mark var as used.

14143 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14145 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14146 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14147 can always succeed if overflow has undefined behavior.
14149 * search.c (boyer_moore, wordify): Remove vars set but not used.
14150 (wordify): Omit three unnecessary tests.
14152 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

14170 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14171 Remove vars that are set but not used.
14172 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.

14180 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14181 that are set but not used.
14183 * xfns.c (make_invisible_cursor): Don't return garbage
14184 if XCreateBitmapFromData fails (Bug#8410).
14186 * xselect.c (x_get_local_selection, x_handle_property_notify):
14187 Remove vars that are set but not used.
14189 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
14190 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

14211 that is set but not used.
14213 * print.c (print_object): Remove var that is set but not used.
14215 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14216 The gnulib version avoids calling malloc in the usual case,
14217 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14218 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14219 * filelock.c (current_lock_owner): Likewise.
14220 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14221 * sysdep.c: Include allocator.h, careadlinkat.h.
14222 (emacs_no_realloc_allocator): New static constant.
14223 (emacs_readlink): New function.
14224 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14225 ../lib/careadlinkat.h.
14227 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14229 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14230 first non-nil return value).

14246 (get_per_char_metric): Remove parameter `f', unused since
14247 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

14292 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
14293 (FletX, Flet): Obey lexical binding.
14294 (Fcommandp): Handle closures.
14295 (Feval): New `lexical' arg.
14296 (eval_sub): New function extracted from Feval. Use it almost
14297 everywhere where Feval was used. Look up vars in lexical env.
14299 (Ffunctionp): Move from subr.el.

14301 (apply_lambda): Remove `eval_flags'.
14302 (funcall_lambda): Handle closures and new byte-code-functions.
14303 (Fspecial_variable_p): New function.
14304 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,

14307 * doc.c (Fdocumentation, store_function_docstring):
14308 * data.c (Finteractive_form): Handle closures.
14310 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14313 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14315 (exec_byte_code): New function extracted from Fbyte_code to handle new
14316 calling convention for byte-code-functions. Add new byte-codes.

14331 (redisplay_window): Even when falling back on "recentering",
14332 position point in the window according to scroll-conservatively,
14333 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14335 (try_scrolling): When point is above the window, allow searching
14336 as far as scroll_max, or one screenful, to compute vertical
14337 distance from PT to the scroll margin position. This prevents
14338 try_scrolling from unnecessarily failing when
14339 scroll-conservatively is set to a value slightly larger than the
14340 window height. Clean up the case of PT below the margin at bottom
14341 of window: scroll_max can no longer be INT_MAX. When aggressive
14342 scrolling is in use, don't let point enter the opposite scroll
14343 margin as result of the scroll.
14344 (syms_of_xdisp) <scroll-conservatively>: Document the
14345 threshold of 100 lines for never-recentering scrolling.

14354 (redisplay_internal): Remove parameter `preserve_echo_area',
14355 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14357 * indent.c (Fvertical_motion):
14358 * window.c (window_scroll_pixel_based, Frecenter):
14359 Don't pass `need_y_p' to `move_it_by_lines'.

14408 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14410 * cm.c (calccost): Turn while-do into do-while, for clarity.
14412 * keyboard.c (syms_of_keyboard): Use the same style as later
14413 in this function when indexing through an array. This also
14414 works around GCC bug 48267.
14416 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14418 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14420 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14421 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14423 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14424 This avoids undefined behavior on integer overflow, and is a bit
14425 more convenient anyway since it is compared to a size_t variable.
14427 Variadic C functions now count arguments with size_t, not int.
14428 This avoids an unnecessary limitation on 64-bit machines, which
14429 caused (substring ...) to crash on large vectors (Bug#8344).
14430 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14431 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14432 All variadic functions and their callers changed accordingly.
14433 (struct gcpro.nvars): Now size_t, not int. All uses changed.

14435 * editfns.c (general_insert_function): Likewise.
14436 * eval.c (struct backtrace.nargs, interactive_p)
14437 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14438 (funcall_lambda, mark_backtrace): Likewise.
14439 * fns.c (concat): Likewise.
14440 * frame.c (x_set_frame_parameters): Likewise.
14441 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14442 0 if not found, not -1. All callers changed.
14444 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14445 (stack_copy_size): Now size_t, not int.
14446 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

14452 All callers changed.
14454 * lisp.h (multibyte_char_to_unibyte):
14455 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14456 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

14462 * xdisp.c (message_dolog, set_message_1): All callers changed.
14464 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14466 * keyboard.c (safe_run_hook_funcall): New function.
14467 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14468 don't set the hook to nil, but remove the offending function instead.
14469 (Qcommand_hook_internal): Remove, unused.
14470 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14471 Vcommand_hook_internal.
14473 * eval.c (enum run_hooks_condition): Remove.
14474 (funcall_nil, funcall_not): New functions.
14475 (run_hook_with_args): Call each function through a `funcall' argument.
14476 Remove `cond' argument, now redundant.

14478 (Frun_hook_with_args_until_failure): Adjust accordingly.
14479 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

14485 * print.c (strout): Remove parameter `multibyte', unused since
14486 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14488 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14489 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14490 All callers changed.
14492 * w32.c (_wsa_errlist): Use braces for struct initializers.

14498 used outside xdisp.c).
14499 (cursor_row_p): Remove parameter `w', unused since
14500 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14502 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14503 All callers changed.
14505 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14507 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

14518 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14520 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

14533 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14535 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14536 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14538 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14540 * w32.c (read_unc_volume): Use parameter `henum', instead of
14541 global variable `wget_enum_handle'.
14543 * keymap.c (describe_vector): Remove parameters `indices' and
14544 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14559 * gtkutil.c (xg_maybe_add_timer):
14560 * keyboard.c (readable_events):
14561 * process.c (wait_reading_process_output):
14562 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
14564 * insdel.c (adjust_markers_gap_motion):
14565 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

14639 2011-03-23 Julien Danjou <julien@danjou.info>
14641 * term.c (Fsuspend_tty, Fresume_tty):
14642 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14643 * window.c (temp_output_buffer_show):

14650 * callint.c (Fcall_interactively):
14651 * buffer.c (Fkill_all_local_variables):
14652 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14654 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14655 unconditionally since it does the check itself.
14657 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14659 Fix more problems found by GCC 4.5.2's static checks.
14661 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14662 the first time through the loop, since we know p0 < p1 then.
14663 This also avoids a gcc -Wstrict-overflow warning.
14665 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14666 leading to a memory leak, possible in functions like
14667 load_charset_map_from_file that can allocate an unbounded number
14668 of objects (Bug#8318).
14670 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14671 that could (at least in theory) be that large.
14673 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14674 This is less likely to overflow, and avoids undefined behavior if
14675 overflow does occur. All callers changed. Use strtoul to scan
14676 for the unsigned long integer.
14677 (pint2hrstr): Simplify and tune code slightly.
14678 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14680 * scroll.c (do_scrolling): Work around GCC bug 48228.
14681 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

14686 This also avoids a warning with gcc -Wstrict-overflow.
14688 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14691 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14693 * process.c (Fmake_network_process): Use socklen_t, not int,
14694 where POSIX says socklen_t is required in portable programs.
14695 This fixes a porting bug on hosts like 64-bit HP-UX, where
14696 socklen_t is wider than int (Bug#8277).
14697 (Fmake_network_process, server_accept_connection):
14698 (wait_reading_process_output, read_process_output):
14701 * process.c: Rename or move locals to avoid shadowing.

14708 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14709 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14711 Make tparam.h and terminfo.c consistent.
14712 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14713 Include tparam.h instead, since it declares them.
14714 * cm.h (PC): Remove extern decl; tparam.h now does this.
14715 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14716 * terminfo.c: Include tparam.h, to check interfaces.
14717 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14718 (tparam): Adjust signature to match interface in tparam.h;
14719 this removes some undefined behavior. Check that outstring and len
14720 are zero, which they always are with Emacs.
14721 * tparam.h (PC, BC, UP): New extern decls.
14723 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14724 (xftfont_open): Rename locals to avoid shadowing.
14726 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14727 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14728 (OTF_TAG_SYM): Omit macro if not needed.
14729 (ftfont_list): Remove unused local.
14730 (get_adstyle_property, ftfont_pattern_entity):
14731 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
14732 Rename locals to avoid shadowing.
14734 * xfont.c (xfont_list_family): Mark var as initialized.
14736 * xml.c (make_dom): Now static.
14738 * composite.c (composition_compute_stop_pos): Rename local to
14740 (composition_reseat_it): Remove unused locals.
14741 (find_automatic_composition, composition_adjust_point): Likewise.
14742 (composition_update_it): Mark var as initialized.
14743 (find_automatic_composition): Mark vars as initialized,
14744 with a FIXME (Bug#8290).
14746 character.h: Rename locals to avoid shadowing.
14747 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14748 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14749 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14750 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14751 to avoid shadowing.
14753 * textprop.c (property_change_between_p): Remove; unused.
14755 * intervals.c (interval_start_pos): Now static.
14757 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
14759 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
14760 Rename locals to avoid shadowing.
14762 * sound.c (wav_play, au_play, Fplay_sound_internal):
14763 Fix pointer signedness.
14764 (alsa_choose_format): Remove unused local var.
14765 (wav_play): Initialize a variable to 0, to prevent undefined
14766 behavior (Bug#8278).
14768 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14770 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14772 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14773 clobbering (Bug#8298).
14774 * sysdep.c (sys_subshell): Likewise.
14775 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14777 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14778 This should get cleaned up, so that child_setup has the
14779 same signature on all platforms.
14781 * callproc.c (call_process_cleanup): Now static.
14782 (relocate_fd): Rename locals to avoid shadowing.
14784 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14786 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14787 not to be necessary, and produces flickering.
14789 2011-03-20 Glenn Morris <rgm@gnu.org>
14791 * config.in: Remove file.
14793 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14795 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14796 are now in src/globals.h.
14797 (syms_of_minibuf): Remove spurious & from previous change.

14807 * xfaces.c (Fx_load_color_file):
14808 Read color file from absolute filename (bug#8250).
14810 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14812 * makefile.w32-in: Update dependencies.
14814 2011-03-17 Eli Zaretskii <eliz@gnu.org>
14816 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

14823 (sigchld_handler): Now static.
14825 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14826 That way, the code declares only the vars that it needs.
14827 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
14828 * s/cygwin.h (PTY_ITERATION): Likewise.
14829 * s/darwin.h (PTY_ITERATION): Likewise.

14832 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
14833 * process.c (allocate_pty): Don't declare stb unless it's needed.
14835 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
14836 (CONSTANTLIM): Remove; unused.
14837 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14838 Define only if needed.
14840 * unexelf.c (unexec): Name an expression,
14841 to avoid gcc -Wbad-function-cast warning.
14842 Use a different way to cause a compilation error if anyone uses
14843 n rather than nn, a way that does not involve shadowing.

14912 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14913 some of which prompt warnings from gcc -Wbad-function-cast.
14914 (Fformat_time_string, Fencode_time, Finsert_char):

14943 (Fmemory_limit): Cast sbrk's returned value to char *.
14945 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

14948 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14950 Use functions, not macros, for up- and down-casing (Bug#8254).
14951 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14952 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14953 to use the following functions instead of these macros.
14954 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14955 EMACS_INT, since callers assume the returned value fits in int.
14956 (upcase1): Likewise, for UPCASE_TABLE.
14957 (uppercasep, lowercasep, upcase): New static inline functions.
14958 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14968 (regex_compile, re_match_2_internal): Mark locals as initialized.
14969 (RETALLOC_IF): Define only if needed.
14970 (WORDCHAR_P): Likewise. This one is never needed, but is used
14971 only in a comment talking about a compiler bug, so put inside
14972 the #if 0 of that comment.
14973 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14974 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

15000 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
15001 New macros, so that the caller can use some names other than
15002 gcpro1, gcpro2, etc.
15003 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15005 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15006 argument, for consistency with GCPRO2_VAR, etc: it is now the
15007 prefix of the variable, not the variable itself. All uses
15009 * dired.c (directory_files_internal, file_name_completion):
15010 Rename locals to avoid shadowing.
15012 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15013 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15014 dired.c's scmp function, had undefined behavior.
15015 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15016 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15017 * buffer.h: ... to here, because these macros use current_buffer,
15018 and the new implementation with inline functions needs to have
15019 current_buffer in scope now, rather than later when the macros
15021 (downcase, upcase1): New static inline functions.
15022 (DOWNCASE, UPCASE1): Reimplement using these functions.
15023 This avoids undefined behavior in expressions like
15024 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15025 from race conditions in accessing the global variables
15026 case_temp1 and case_temp2.
15027 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15028 * lisp.h (case_temp1, case_temp2): Remove their decls.
15029 * character.h (ASCII_CHAR_P): Move from here ...
15030 * lisp.h: ... to here, so that the inline functions mentioned
15031 above can use them.
15033 * dired.c (directory_files_internal_unwind): Now static.
15035 * fileio.c (file_name_as_directory, directory_file_name):

15038 (file_name_as_directory): Use const pointers when appropriate.
15039 (Fexpand_file_name): Likewise. In particular, newdir might
15040 point at constant storage, so make it a const pointer.
15041 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
15042 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15044 (Fset_file_times, Finsert_file_contents, auto_save_error):

15049 to avoid shadowing.
15051 * marker.c (bytepos_to_charpos): Remove; unused.
15053 * lisp.h (verify_bytepos, count_markers): New decls,
15054 so that gcc does not warn that these functions aren't declared.
15056 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
15057 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
15058 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
15059 (copy_text): Remove unused local var.
15061 * filelock.c (within_one_second): Now static.
15062 (lock_file_1): Rename local to avoid shadowing.
15064 * buffer.c (fix_overlays_before): Mark locals as initialized.
15065 (fix_start_end_in_overlays): Likewise. This function should be
15066 simplified by using pointers-to-pointers, but that's a different
15068 (switch_to_buffer_1): Now static.
15069 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15070 (report_overlay_modification): Rename locals to avoid shadowing.
15072 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
15073 Fix pointer signedness issue.
15074 (sys_subshell): Mark local as volatile if checking for lint,
15075 to suppress a gcc -Wclobbered warning that does not seem to be right.
15076 (MAXPATHLEN): Define only if needed.
15078 * process.c (serial_open, serial_configure): Move decls from here ...
15079 * systty.h: ... to here, so that they can be checked.
15081 * fns.c (get_random, seed_random): Move extern decls from here ...
15082 * lisp.h: ... to here, so that they can be checked.
15084 * sysdep.c (reset_io): Now static.
15085 (wait_for_termination_signal): Remove; unused.
15087 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

15092 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
15093 (describe_map_tree):
15094 Rename locals to avoid shadowing.
15096 * keyboard.c: Declare functions static if they are not used elsewhere.

15181 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
15182 These macros can no longer be used for assignment.

15243 For example, without this patch (encode-time 0 0 0 1 1
15244 1152921504606846976) returns the obviously-bogus value (-948597
15245 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
15246 reports time overflow. See
15247 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
15248 * deps.mk (editfns.o): Depend on ../lib/intprops.h.

15263 * editfns.c (time_overflow): New function, refactoring common code.
15264 (Fformat_time_string, Fdecode_time, Fencode_time):
