3 port new setting code to Sun C 5.8 2005/10/13
4 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5 Return void, not Lisp_Object. Otherwise, the compiler
6 complains about (A?B:C) where B is void and C is Lisp_Object
7 when compiling CHAR_TABLE_SET, due to the recent change to
8 the API of sub_char_table_set_contents.

392
393 Use bool, not int, for Lisp booleans.
394 This is more natural, and on my platform (GCC 4.7.1 x86-64) it
395 makes Emacs a bit smaller and presumably a bit faster.
396 * lisp.h: Include <stdbool.h>.
397 (struct Lisp_Boolfwd, defvar_bool):
398 * lread.c (defvar_bool): Use bool, not int, for Lisp booleans.

837
838 2012-08-04 Eli Zaretskii <eliz@gnu.org>
839
840 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
841 * w32.c (init_environment): Change the default values of many
842 environment variables in dflt_envvars[] to NULL, to avoid pushing
843 them into environment when they were not already defined.
844 Remove the code that deletes site-lisp subdirectories from the default
845 value of EMACSLOADPATH, as it is no longer needed.
846 (check_windows_init_file): Now external, not static.
847 Use Vload_path as is, without adding anything, as this function is now
848 called when Vload_path is already set up.
849
850 * w32.h (check_windows_init_file): Add prototype.
851
852 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
853 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
854 compatibility with Posix platforms.
855 (main): Move the call to check_windows_init_file to here from
856 w32.c.
857 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
858 any, in the DEFALT argument into the root of the Emacs build or
859 installation tree, as appropriate.
860
861 * callproc.c (init_callproc_1): Call decode_env_path instead of
862 doing its equivalent by hand.
863 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
864 the code that sets Vexec_path run on MS-Windows.
865
866 * lread.c (init_lread): Add comments to #ifdef's.
867
868 * msdos.c (dos_set_window_size, IT_update_begin)
869 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
870 instead of direct references.
871
872 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
873
874 Export DEFAULT_REHASH_* to GDB.
875 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
876 Now constants, not macros.
877
878 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
879
880 Remove unnecessary casts involving pointers.
881 These casts are no longer needed now that we assume C89 or later,
882 since they involve casting to or from void *.
883 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
884 (make_pure_float, make_pure_vector):
885 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

893 * xselect.c (x_stop_queuing_selection_requests)
894 (x_get_window_property, x_get_window_property_as_lisp_data):
895 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
896 Remove unnecessary pointer casts.
897 * alloc.c (record_xmalloc): New function.
898 * lisp.h (record_xmalloc): New decl.
899 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
900 more like a function. This is because the pointer cast is not
901 needed. All uses changed.
902 * print.c (print_string, print_error_message): Avoid length recalc.
903
904 Improve fix for macroexp crash with debugging (Bug#12118).
905 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
906 ARRAY_MARK_FLAG when checking subscripts, because ASET is
907 not supposed to be invoked from the garbage collector.
908 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
909 (gc_aset): New function, which is like ASET but can be
910 used in the garbage collector.
911 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
912 (set_hash_index): Use it instead of ASET.
913

921 <g_b_init_create_symbolic_link>: New static flags.
922 (globals_of_w32): Initialize them to zero.
923 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
924 (map_w32_filename): Improve commentary. Simplify switch.
925 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
926 headers (most versions of MinGW w32api don't).
927 (get_security_info, create_symbolic_link)
928 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
929 New functions.
930 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
931 in the argument file name.
932 (sys_access): Call unc_volume_file_attributes only if
933 GetFileAttributes fails with network-related error codes.
934 (sys_rename): Diagnose renaming of a symlink when the user doesn't
935 have the required privileges.
936 (get_file_security_desc_by_name): Rename from
937 get_file_security_desc.
938 (stat_worker): New function, with most of the guts of 'stat', and
939 with addition of handling of symlinks and support for 'lstat'.
940 If possible, get file's attributes and security information by
941 handle, not by name. Produce S_IFLNK bit for symlinks, when
942 called from 'lstat'.
943 (stat, lstat): New functions, call 'stat_worker'.
944 (symlink, readlink, careadlinkat): Rewritten to create and resolve
945 symlinks when the underlying filesystem supports them.
946
947 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
948
949 Fix macroexp crash on Windows with debugging (Bug#12118).
950 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
951 checking subscripts; problem introduced with the recent
952 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
953 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
954 since it's used in non-static inline functions now.
955
956 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
957 Don't assume buffer size fits in 'int'. Remove unused local.
958
959 Use C99-style 'extern inline' if available.
960 * buffer.h (BUFFER_INLINE):
961 * category.h (CATEGORY_INLINE):

969 * buffer.h, category.h, character.h, charset.h, composite.h:
970 * dispextern.h, lisp.h, systime.h:
971 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
972 * alloc.c (LISP_INLINE):
973 * buffer.c (BUFFER_INLINE):
974 * category.c (CATEGORY_INLINE):
975 * character.c (CHARACTER_INLINE):
976 * charset.c (CHARSET_INLINE):
977 * composite.c (COMPOSITE_INLINE):
978 * dispnew.c (DISPEXTERN_INLINE):
979 * sysdep.c (SYSTIME_INLINE):
980 Define to EXTERN_INLINE, so that the corresponding functions
981 are compiled into code.
982 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
983 (INLINE_HEADER_END): New macros.
984 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,
985 since it's used in non-static inline functions now.
986 (VALMASK) [!USE_LSB_TAG]: Likewise.
987
988 2012-08-02 Glenn Morris <rgm@gnu.org>

1004 hard-coding the path separator.
1005
1006 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
1007
1008 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
1009 This how ASET and AREF are supposed to work, and makes
1010 it easier to think about future improvements. See
1011 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
1012 * charset.h (set_charset_attr): New function.

1425 list.
1426
1427 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for

1429 with other headers and sources, such as gmalloc.c and the
1430 MS-Windows system headers. All users changed.
1431
1432 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
1433
1434 Revert last save_excursion_save and save_excursion_restore changes.

1437
1438 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
1439
1440 Fix recently-introduced typos in Windows port.
1441 Reported by Martin Rudalics <rudalics@gmx.at>.

1445 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
1446

1448 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
1449 arms of an 'if', not using conditional expressions; otherwise GDB
1450 complains about the types in the unevaluated arm when the argument
1451 is an integer literal.
1452 (xgetint): Simplify expression.
1453 * alloc.c (gdb_make_enums_visible): New constant. This ports to
1454 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
1455 Zaretskii in <http://bugs.gnu.org/12036#13>.
1456 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
1457 needed now that we have gdb_make_enums_visible.
1458 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
1459 (enum enum_USE_LSB_TAG):
1460 New enum types, packaging up enums that need to be exported to GDB.
1461
1462 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
1463
1464 Utility function to make a list from specified amount of objects.

1483 Fast save_excursion_save and save_excursion_restore.
1484 * lisp.h (struct Lisp_Excursion): New data type.
1485 (PVEC_EXCURSION): New pseudovector type.
1486 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
1487 to deal with it. Adjust comments.
1488 (init_marker, attach_marker): New prototype.
1489 (unchain_marker): Adjust prototype.
1490 * marker.c (attach_marker): Change to global.
1491 (init_marker): New function.
1492 * alloc.c (Fmake_marker, build_marker): Use it.
1493 (build_marker): More easserts.
1494 (mark_object): Handle struct Lisp_Excursion.
1495 * editfns.c (save_excursion_save, save_excursion_restore):
1496 Reimplement to use struct Lisp_Excursion. Add comments.

1498 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
1499
1500 Fix export of symbols to GDB (Bug#12036).
1501 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
1502 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
1503 emacs.c, as this is a more-suitable home. Had this been done earlier
1504 the fix for 12036 would have avoided some of the problems noted in
1505 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
1506 would have been more obvious.
1507 * emacs.c: Do not include <verify.h>; no longer needed.
1508 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

1513 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
1514 (DATA_SEG_BITS): Use it.
1515 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
1516 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1517 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1518 not be usable in #if. This simplifies things.
1519
1520 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1521
1522 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
1523
1524 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
1525
1526 Simplify export of symbols to GDB (Bug#12036).
1527 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1528 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1529 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1530 Adjust to changes in lisp.h and emacs.c, by using
1531 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1532 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1533 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1534 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
1535 instead of gdb_valbits.
1536 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
1537 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
1538 instead of gdb_array_mark_flag.
1539 (xboolvector): Get size from $->size, not $->header.size.
1540 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1541 (xreload, hook-run, hookpost-run): Remove.
1542 * emacs.c: Include <verify.h>.
1543 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1544 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
1545 Remove.
1546 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
1547 (gdb_USE_LSB_TAG): New enum constants.
1548 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1549 Also define these as enum constants, so they're visible to GDB.
1550 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
1551 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
1552 as constants, so they're visible to GDB.
1553 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
1554 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
1555 Now enum constants, not macros, so they're visible to GDB.
1556 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1557 more convenient now. All uses changed.
1558 (VALMASK) [USE_LSB_TAG]: Also define in this case.
1559 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
1560
1561 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
1562
1563 Explicitly free restriction data that are not needed anymore.
1564 * editfns.c (save_restriction_restore): Free restriction data.
1565
1566 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
1567
1568 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
1569 add argument, tune behavior, and adjust all callers.
1570
1571 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
1572
1573 Use typedef for EMACS_INT, EMACS_UINT.
1574 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1575 than macros. This simplifies debugging in the usual case, since
1576 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1577 and it allows expressions involving EMACS_INT casts.
1578 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1579
1580 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
1581
1582 * nsterm.m (ns_read_socket): Return early if there is a modal
1583 window (Bug#12043).
1584
1585 2012-07-25 Martin Rudalics <rudalics@gmx.at>
1586
1587 * frame.c (Fredirect_frame_focus): In doc-string don't mention
1588 that FOCUS-FRAME can be omitted.
1589
1590 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
1591
1592 Adjust buffer text indirection counters at the end of Fkill_buffer.
1593 * buffer.c (Fkill_buffer): Adjust indirection counters when the
1594 buffer is definitely dead. This should really fix an issue reported
1595 by Christoph Scholtes again. (Bug#12007).
1596 (init_buffer_once): Initialize indirection counters of
1597 buffer_defaults and buffer_local_symbols (for sanity and safety).
1598
1599 2012-07-24 Eli Zaretskii <eliz@gnu.org>
1600
1601 * xdisp.c (init_iterator): Don't compute dimensions of truncation
1602 and continuation glyphs on tooltip frames, leave them at zero.

1610
1611 2012-07-23 Eli Zaretskii <eliz@gnu.org>
1612
1613 * print.c (print_object): Don't crash when a frame's name is nil
1614 or invalid. (Bug#12025)
1615
1616 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
1617 it signals an error when a tooltip frame is being created.
1618
1619 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1620
1621 Cleanup miscellaneous objects allocation and initialization.
1622 * alloc.c (allocate_misc): Change to static. Add argument to
1623 specify the subtype. Adjust comment and users.
1624 (build_overlay): New function.
1625 * buffer.c (copy_overlays, Fmake_overlay): Use it.
1626 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
1627 (allocate_misc): Remove prototype.
1628 (build_overlay): Add prototype.
1629
1630 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1631
1632 Swap buffer text indirection counters in Fbuffer_swap_text.
1633 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1634 This avoids crash reported by Christoph Scholtes at
1635 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1636
1637 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1638
1639 * nsmenu.m (Popdown_data): New struct.
1640 (pop_down_menu): p->pointer is Popdown_data. Release the pool and

2395 EMACS_TIME simplification (Bug#11875).
2396 This replaces macros (which typically do not work in GDB)

2398 The functional style also makes code easier to read and maintain.
2399 * systime.h: Include <sys/time.h> on all hosts, not just if
2400 WINDOWSNT, since 'struct timeval' is needed in general.
2401 (EMACS_TIME): Now a typedef, not a macro.
2402 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
2403 not macros.

2413 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
2414 not functions. All uses rewritten to use the following, respectively:
2415 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
2416 (add_emacs_time, sub_emacs_time): New functions.
2417 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

2419 * xterm.c (XTflash): Get the current time closer to when it's used.
2420 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

2434 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
2435 (menu_separator_name_p):
2436 * nsmenu.m (ns_update_menubar):
2437 Prefer memcmp to strncmp when either will do.
2438 * nsterm.m: Include <ftoastr.h>.
2439 (ns_get_color):
2440 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
2441 Prefer snprintf to strncpy.
2442 * nsterm.m (ns_term_init):
2443 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2444 * nsterm.m (ns_term_init):
2445 Avoid the need for strncpy, by using build_string or
2446 make_unibyte_string directly. Use dtoastr, not snprintf.
2447 * process.c (Fmake_network_process): Diagnose service names that
2448 are too long, rather than silently truncating them or creating
2449 non-null-terminated names.
2450 (Fnetwork_interface_info): Likewise, for interface names.
2451 * sysdep.c (system_process_attributes) [GNU_LINUX]:
2452 Prefer sprintf to strncat.
2453 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
2454 Prefer vsnprintf to vsprintf + strncpy.
2455
2456 2012-07-10 Glenn Morris <rgm@gnu.org>
2457
2458 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
2459 Clarify fallback case.
2460
2461 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

2464 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
2465 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
2466 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
2467 where argument type is known to be a Lisp_Cons.

2477 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2478
2479 Optimize pure C strings initialization.
2480 * lisp.h (make_pure_string): Fix prototype.
2481 (build_pure_c_string): New function, defined as static inline. This
2482 provides a better opportunity to optimize away calls to strlen when
2483 the function is called with compile-time constant argument.
2484 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2485 argument, adjust users accordingly. Use build_pure_c_string where
2486 appropriate.
2487 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2488 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,

2494 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
2495 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
2496 * lread.c (openp): Likewise.
2497
2498 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2499
2500 Avoid calls to strlen in path processing functions.
2501 * fileio.c (file_name_as_directory): Add comment. Change to add
2502 srclen argument and return the length of result. Adjust users
2503 accordingly.
2504 (directory_file_name): Fix comment. Change to add srclen argument,
2505 swap 1st and 2nd arguments to obey the common convention.
2506 Adjust users accordingly.
2507 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2508
2509 2012-07-10 Glenn Morris <rgm@gnu.org>
2510
2511 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
2512 Move PENDING_OUTPUT_COUNT definition to configure.
2513
2514 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
2515 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):

2517
2518 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2519 We include usg5-4-common.h, which defines them both.
2520
2521 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2522 O_RDONLY already includes it).
2523
2524 Stop ns builds setting the EMACSLOADPATH environment variable.
2525 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2526 Now it does not set EMACSLOADPATH, just returns the load-path string.
2527 * nsterm.h: Update accordingly.
2528 * lread.c [HAVE_NS]: Include nsterm.h.
2529 (init_lread) [HAVE_NS]: Use ns_load_path.
2530 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
2531
2532 2012-07-09 Glenn Morris <rgm@gnu.org>
2533
2534 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2535 since the included bsd-common.h does so.
2536
2537 Stop ns builds setting the EMACSPATH environment variable.
2538 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2539 (ns_init_paths): Do not set EMACSPATH.
2540 * nsterm.h (ns_exec_path): Add it.

2545
2546 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2547
2548 * process.c (wait_reading_process_output): 'waitchannels' was unset
2549 when read_kbd || !NILP (wait_for_cell); fix this.
2550
2551 Add GCC-style 'const' attribute to functions that can use it.
2552 * character.h (char_resolve_modifier_mask):
2553 * keyboard.h (make_ctrl_char):
2554 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
2555 (init_character_once, next_almost_prime, init_fns, init_image)
2556 (flush_pending_output, init_sound):
2557 * mem-limits.h (start_of_data):
2558 * menu.h (finish_menu_items):
2559 Add ATTRIBUTE_CONST.
2560 * emacs.c (DEFINE_DUMMY_FUNCTION):
2561 Declare the dummy function with ATTRIBUTE_CONST.
2562 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2563 Add decls with ATTRIBUTE_CONST.
2564
2565 Minor improvements to make_formatted_string.
2566 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2567 where int is good enough, as vsprintf returns an int.
2568 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2569
2570 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2571
2572 Use make_formatted_string to avoid double length calculation.

2591 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
2592 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
2593 * nsterm.h (ns_etc_directory): Add it.
2594 * callproc.c [HAVE_NS]: Include nsterm.h.
2595 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
2596
2597 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2598
2599 Move marker debugging code under MARKER_DEBUG.
2600 * marker.c (MARKER_DEBUG): Move marker debugging code under
2601 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2602 for bootstrap with --enable-checking (~3x slowdown reported
2603 by Juanma Barranquero <lekktu@gmail.com>).
2604 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2605
2606 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2607
2608 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2609 See <http://bugs.gnu.org/11825#29>.
2610
2611 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2612
2613 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2614 has no font, use the frame's font. (Bug#11813)
2615 (display_line): Add commentary about displaying truncation glyphs
2616 on GUI frames.
2617 (produce_special_glyphs): Move here from term.c.
2618
2619 * term.c (produce_special_glyphs): Move to xdisp.c.
2620
2621 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2622 section.
2623
2624 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2625
2626 * xdisp.c (display_line): Avoid warning about implicit declaration
2627 of FRAME_FONT.
2628
2629 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2630
2631 * lisp.h: Remove empty conditional.
2632
2633 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2634
2635 * lread.c (load_path_check): Now static.
2636
2637 Fix some minor --with-ns problems found by static checking.
2638 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2639 (x_set_font) [!HAVE_X_WINDOWS]:
2640 * image.c (xpm_load_image) [HAVE_NS]:
2641 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2642 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2643 Remove unused local.
2644 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2645 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2646 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2647 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2648 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2649 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2650 Fix pointer signedness problem.
2651 * xfaces.c (FRAME_X_FONT_TABLE):
2652 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2653
2654 2012-07-07 Glenn Morris <rgm@gnu.org>
2655
2656 * lread.c (load_path_check): New function, split from init_lread.
2657 (init_lread): Reorganize. Motivation:
2658 If EMACSLOADPATH is set, check/warn about that rather than the
2659 defaults, which we are not going to use. Hence we can remove
2660 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2661 Don't warn if site-lisp directories are missing.
2662 If not installed, start from a blank load-path, since
2663 PATH_LOADSEARCH refers to the eventual installation directories.
2664
2665 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2666
2667 Support truncation and continuation glyphs on GUI frames, when
2668 fringes are disabled. (Bug#11832)
2669 * xdisp.c (init_iterator): Get dimensions of truncation and
2670 continuation glyphs even if on GUI frames.
2671 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2672 or both, are absent.
2673 (start_display, move_it_in_display_line_to): Handle the case of a
2674 GUI frame without a fringe to display continuation or truncation
2675 glyphs.
2676 (insert_left_trunc_glyphs): Support GUI frames: make sure
2677 truncation glyphs overwrite enough glyphs from the current line to
2678 have sufficient space in pixels.
2679 (display_line): Support truncation and continuation glyphs on GUI
2680 frames. If some spare pixels are left on the line after inserting
2681 the truncation glyphs, fill that space with a stretch glyph of a
2682 suitably computed width.
2683
2684 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2685 produce_glyphs, to support GUI sessions.
2686
2687 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2688
2689 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2690
2691 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2692
2693 Do not require float-time's arg to fit in time_t (Bug#11825).
2694 This works better on hosts where time_t is unsigned, and where
2695 float-time is applied to the (negative) difference between two times.
2696 * editfns.c (decode_time_components): Last arg is now double *,
2697 not int *, and means to store all the result as a double, without
2698 worrying about whether the seconds part fits in time_t.
2699 All callers changed.
2700 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2701 All callers changed.
2702 (Ffloat_time): Do not fail merely because the specified time falls
2703 outside of time_t range.
2704
2705 2012-07-07 Glenn Morris <rgm@gnu.org>
2706
2707 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
2708 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
2709 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
2710
2711 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
2712
2713 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2714 Update dependencies.
2715
2716 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2717
2718 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2719
2720 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
2721 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
2722 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2723 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2724 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2725 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2726
2727 * xfont.c (compare_font_names): Redo to omit the need for casts.
2728
2729 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2730
2731 * xfns.c (Fx_change_window_property): Doc fix.
2732 * w32fns.c (Fx_change_window_property): Doc fix.
2733
2734 * w32fns.c (Fx_window_property): Accept the same arguments as the
2735 X Windows version. Doc fix.
2736 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2737
2738 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2739 Eli Zaretskii <eliz@gnu.org>
2740
2741 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2742 Windows-specific code from nt/config.nt moved here.
2743 Obsolete settings removed.
2744
2745 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2746
2747 * process.c: Avoid unnecessary calls to gettime.
2748 (wait_reading_process_output): Don't get the time of day
2749 when gobbling data immediately and not waiting, as there's no need
2750 for it in that case. This removes a FIXME.
2751
2752 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2753
2754 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2755 is defined (Bug#11768).
2756
2757 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2758
2759 Fix marker debugging code.
2760 * marker.c (byte_char_debug_check): Do not perform the check
2761 if buffer is not multibyte.
2762 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2763 Call byte_char_debug_check with correct arguments.
2764
2765 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2766
2767 Compile marker debugging code only if ENABLE_CHECKING is defined.
2768 * marker.c (byte_char_debug_check, count_markers):
2769 Use only if ENABLE_CHECKING is defined.
2770 (byte_debug_flag): Remove.
2771 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2772 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2773
2774 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2775
2776 Avoid code repetition in marker-related functions.
2777 * marker.c (attach_marker): New function.
2778 (Fset_marker, set_marker_restricted, set_marker_both)
2779 (set_marker_restricted_both): Use it.
2780 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2781 Consistently rename charno to charpos.
2782 (marker_position): Add eassert.
2783 (marker_byte_position): Convert to eassert.
2784
2785 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2786
2787 Simplify list operations in unchain_overlay and unchain_marker.
2788 * buffer.c (unchain_overlay): Simplify. Add comment.
2789 * marker.c (unchain_marker): Simplify. Fix comments.
2790
2791 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2792
2793 Introduce fast path for the widely used marker operation.
2794 * alloc.c (build_marker): New function.
2795 * lisp.h (build_marker): New prototype.
2796 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
2797 * composite.c (autocmp_chars): Likewise.
2798 * editfns.c (buildmark): Remove.
2799 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2800 (save_restriction_save): Use build_marker.

2805
2806 Do not use Fdelete_overlay in delete_all_overlays
2807 to avoid redundant calls to unchain_overlay.
2808 * buffer.c (drop_overlay): New function.
2809 (delete_all_overlays, Fdelete_overlay): Use it.
2810 * minibuf.c (get_minibuffer): Fix comment.
2811
2812 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2813
2814 Port to OpenBSD 5.1 amd64.
2815 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2816 This is needed for OpenBSD, and should be harmless on all BSD systems.
2817 Also, include <sys/sysctl.h>, as it should be available on all
2818 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2819 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2820 use p_pid member, not kp_proc.pid.
2821
2822 2012-07-06 Glenn Morris <rgm@gnu.org>
2823
2824 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2825
2826 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2827
2828 More xmalloc and related cleanup.
2829 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2830 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
2831 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

2833 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
2834 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
2835 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:

2837 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2838 * xterm.c:
2839 Omit needless casts involving void * pointers and allocation.
2840 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2841 as the former is more robust if P's type is changed.
2842 Prefer xzalloc to xmalloc + memset 0.
2843 Simplify malloc-or-realloc to realloc.
2844 Don't worry about xmalloc returning a null pointer.
2845 Prefer xstrdup to xmalloc + strcpy.
2846 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2847 growing it.
2848 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2849 alloca of a constant.
2850
2851 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2852
2853 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2854 hscroll is larger than the line width. Fixes long and futile
2855 looping inside extend_face_to_end_of_line (on a TTY) producing
2856 glyphs that are not needed and thrown away.

2866
2867 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
2868
2869 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
2870 not defined (Bug#11768).
2871 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
2872 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)

2886 * xdisp.c (window_hscroll_limited): New function.
2887 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2888 coordinates when window's hscroll is set to insanely large
2889 values. (Bug#11857)
2890
2891 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2892

2953
2954 * fileio.c (time_error_value): Check the right error number.
2955 Problem reported by Troels Nielsen in
2956 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2957
2958 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2959
2960 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2961 This should be fixed in a better way; see Eli Zaretskii in
2962 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2963 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2964
2965 * fileio.c (time_error_value): Rename from special_mtime.
2966 The old name's problems were noted by Eli Zaretskii in
2967 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2968
2969 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2970 This variable's comment says Emacs needs at least one GDB-visible
2971 symbol of type enum pvec_type, to work around GDB problems.
2972 The symbol's value doesn't matter.
2973
2974 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2975 that causes compilation to fail on pre-C99 compilers.
2976
2977 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2978
2979 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

2989
2990 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2991 * lisp.h (enum pvec_type): Use fewer bits.
2992 (PSEUDOVECTOR_SIZE_BITS): New constant.
2993 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2994 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2995 change in pvec_type.
2996 (PSEUDOVECTOR_TYPEP): New macro.
2997 (TYPED_PSEUDOVECTORP): Use it.
2998 * fns.c (internal_equal): Adapt code to extract pvectype.
2999 * emacs.c (gdb_pvec_type): Update type.
3000 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
3001 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
3002 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
3003 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
3004 (sweep_vectors): Use it. Use local var `total_bytes' instead of
3005 abusing vector->header.next.nbytes.
3006 (live_vector_p): Use PVEC_TYPE.
3007 (mark_object): Adapt code to extract pvectype. Use switch.
3008
3009 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3010
3011 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
3012 Tighten new eassert a bit.
3013
3014 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3015
3016 Fix compilation with --enable-gcc-warnings and -O1
3017 optimization level.
3018 * doprnt.c (doprnt): Change type of tem to int, initialize
3019 to avoid compiler warning. Add eassert.
3020 * search.c (simple_search): Initialize match_byte to avoid
3021 compiler warning. Add eassert.
3022
3023 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3024
3025 Avoid weird behavior with large horizontal scrolls.
3026 Without this change, for example, large hscroll values would
3027 mess up Emacs's display on Fedora 15 x86, presumably due to
3028 overflows in int calculations in the display code.
3029 Also, if buffers had long lines, Emacs would freeze.
3030 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
3031 (set_window_hscroll): New function, containing the old guts of
3032 Fset_window_hscroll. Return the clipped value.
3033 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
3034 This avoids the need to check against PTRDIFF_MAX.
3035
3036 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
3037
3038 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3039
3040 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
3041
3042 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3043
3044 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
3045 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
3046 since GCC 4.4.6 issues a bogus warning for them.
3047
3048 Fix bugs in file timestamp newness comparisons.
3049 * fileio.c (Ffile_newer_than_file_p):
3050 * lread.c (Fload): Use full timestamp resolution of files,
3051 not just the 1-second resolution, so that files that are only
3052 slightly newer still count as newer.
3053 * fileio.c (Ffile_newer_than_file_p): Don't assume file
3054 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
3055
3056 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
3057
3058 * fileio.c: Improve handling of file time marker. (Bug#11852)
3059 (special_mtime): New function.
3060 (Finsert_file_contents, Fverify_visited_file_modtime):
3061 Use it to set special mtime values consistently.
3062
3063 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
3064
3065 * fileio.c (Finsert_file_contents): Properly handle st_mtime
3066 marker for non-existing file. (Bug#11852)
3067
3068 2012-07-03 Glenn Morris <rgm@gnu.org>
3069
3070 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
3071 and did not make it into globals.h).
3072
3073 2012-07-03 Tom Tromey <tromey@redhat.com>
3074
3075 * window.c (Fset_window_margins, Fset_window_fringes)
3076 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

3113 * lisp.h (Frandom): Make it visible to C.
3114 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
3115 buffer for invisible buffers. (Bug#1229)
3116
3117 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3118
3119 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
3120 values which aren't power of 2.
3121 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
3122 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
3123 accordingly.
3124
3125 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
3126
3127 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
3128
3129 * alloc.c (mark_object): Revert part of last patch to use `switch'.
3130
3131 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3132
3133 * alloc.c (allocate_vector_block): Remove redundant
3134 calls to mallopt if DOUG_LEA_MALLOC is defined.
3135 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
3136 avoid calls to mallopt if zero_vector is returned.
3137
3138 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3139
3140 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES

3145
3146 Cleanup basic buffer management.
3147 * buffer.h (struct buffer): Change layout to use generic vector
3148 marking code. Fix some comments. Change type of 'clip_changed'
3149 to bitfield. Remove unused #ifndef old.
3150 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
3151 (GET_OVERLAYS_AT): Fix indentation.
3152 (for_each_per_buffer_object_at): New macro.
3153 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
3154 (Fbuffer_local_variables): Use it.
3155 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
3156 * alloc.c (allocate_buffer): Adjust to match new layout of
3157 struct buffer. Fix comment.
3158 (mark_overlay): New function.
3159 (mark_buffer): Use it. Use mark_vectorlike to mark normal
3160 Lisp area of struct buffer.
3161 (mark_object): Use it. Adjust marking of misc objects
3162 and related comments.
3163
3164 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
3165
3166 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
3167 wrapper that is not needed because the wrapped code is a no-op (zero
3168 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
3169 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
3170
3171 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
3172
3173 * alloc.c (mark_buffer): Simplify. Remove prototype.
3174 (mark_object): Add comment. Reorganize marking of vector-like
3175 objects. Use CHECK_LIVE for all vector-like objects except buffers
3176 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
3177 Avoid redundant calls to mark_vectorlike for bool vectors.
3178
3179 2012-06-30 Glenn Morris <rgm@gnu.org>
3180
3181 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
3182
3183 * epaths.in (PATH_SITELOADSEARCH): New.
3184 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
3185 This is rather than relying on --enable-locallisppath elements
3186 having "site-lisp" in their names. (Bug#10208#25, 11658)
3187
3188 2012-06-30 Eli Zaretskii <eliz@gnu.org>
3189
3190 * w32proc.c (sys_select): Accept and ignore one more argument.
3191
3192 * w32.c (emacs_gnutls_pull): Call select with one more argument.
3193
3194 * sysselect.h [DOS_NT]: Don't include sys/select.h.
3195 (pselect) [!MS_DOS]: Redirect to sys_select.
3196
3197 * sysdep.c: Don't include dos.h and dosfns.h.
3198
3199 * process.c (sys_select):
3200 * msdos.c (sys_select): Accept one more argument and ignore it.
3201
3202 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
3203 adapt data types and code to that.
3204
3205 * dosfns.c:
3206 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
3207 which clashes with the gnulib function of the same name.
3208
3209 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3210
3211 * font.c (font_style_to_value, font_style_symbolic)
3212 (font_prop_validate_style): Add type checks for values in
3213 font_style_table.
3214
3215 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3216 argument.
3217 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3218 uses.
3219
3220 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3221
3222 * xdisp.c (try_window_id): Undo last change.
3223
3224 * w32.c (getwd): Adjust commentary about startup_dir.
3225 (init_environment): Always call sys_access, even in non-MSVC
3226 builds. Don't chdir to the directory of the Emacs executable.
3227 This undoes code from 1997 which was justified by the need to
3228 "avoid conflicts when removing and renaming directories". But its
3229 downside was that every relative file name was being interpreted
3230 relative to the directory of the Emacs executable, which can never
3231 be TRT. In particular, it broke sys_access when called with
3232 relative file names.
3233 (sys_access): Map GetLastError to errno.
3234
3235 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3236
3237 * window.h (struct window): Change type of 'fringes_outside_margins'
3238 to bitfield. Fix comment. Adjust users accordingly.
3239 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
3240 Adjust comment.
3241 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3242 to ptrdiff_t.
3243
3244 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
3245
3246 * gnutls.c (emacs_gnutls_handshake):
3247 Add QUIT to make the loop interruptible.
3248
3249 2012-06-29 Glenn Morris <rgm@gnu.org>
3250
3251 * charset.c (init_charset): Make lack of etc/charsets fatal.
3252
3253 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3254
3255 * editfns.c (region_limit): Fix type mismatch.
3256
3257 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3258
3259 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3260 undefined. Convert from xassert to eassert.
3261 * nsmenu.m: Convert from xassert to eassert.
3262 * nsterm.m: Likewise.
3263
3264 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3265
3266 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3267
3268 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3269
3270 Avoid integer overflow on scroll-left and scroll-right.
3271 * window.c (HSCROLL_MAX): New macro.
3272 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3273 overflow when requested scroll falls outside ptrdiff_t range.
3274
3275 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3276
3277 * window.h (struct window): Change type of 'hscroll',
3278 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3279 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3280 Adjust users accordingly.
3281 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3282 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3283 from EMACS_INT to ptrdiff_t.
3284 (make_window): Omit redundant initialization.
3285
3286 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
3287

3416
3417 * alloc.c: Remove build_string.
3418 * lisp.h: Define build_string as static inline. This provides

3426
3427 Use sprintf return value instead of invoking strlen on result.
3428 In the old days this wasn't portable, since some sprintf
3429 implementations returned char *. But they died out years ago and
3430 Emacs already assumes sprintf returns int.
3431 Similarly for float_to_string.
3432 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
3433 * ccl.c (ccl_driver):

3439 * xfns.c (syms_of_xfns):
3440 Use sprintf or float_to_string result to avoid need to call strlen.
3441 * data.c (Fnumber_to_string):
3442 Use make_unibyte_string, since the string must be ASCII.
3443 * lisp.h, print.c (float_to_string): Now returns int length.
3444 * term.c (produce_glyphless_glyph):
3445 Use sprintf result rather than recomputing it.
3446
3447 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3448 * Makefile.in (ALL_CFLAGS):

3471 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
3472
3473 * gtkutil.c (get_utf8_string): Remove redundant assignment.
3474 sprintf already null-terminates its output.
3475
3476 * xfns.c (x_window): Remove redundant cast.
3477
3478 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3479
3480 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
3481 `const char *' to `char *' to avoid compiler warning.

3484
3485 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
3486 instead of truncating it to 63 (admittedly a generous limit).

3543 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
3544 * lisp.h (WAIT_READING_MAX): New macro.
3545 * dispnew.c (Fsleep_for, sit_for):
3546 * keyboard.c (kbd_buffer_get_event):
3547 * process.c (Faccept_process_output):
3548 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3549 This improves on the previous patch, which introduced a bug
3550 when time_t is unsigned and as wide as intmax_t.
3551 See <http://bugs.gnu.org/9000#51>.
3552
3553 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3572 All uses changed.
3573 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
3574 not make_lisp_timeval, when the argument is of type EMACS_TIME.

3616 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3617
3618 Support higher-resolution time stamps (Bug#9000).
3619 The time stamps are only nanosecond-resolution at the C level,
3620 since that's the best that any real-world system supports now.
3621 But they are picosecond-resolution at the Lisp level, as that's
3622 easy, and leaves room for future OS improvements.
3623
3624 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3625 (LIBES): Use it.
3626
3627 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3628 Don't get current time unless it's needed.
3629
3630 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3631 now provides it if it's absent.
3632 (start_atimer): Port to higher-res time stamps.
3633 Check for time stamp overflow. Don't get current time more
3634 often than is needed.
3635
3636 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3637 Include systime.h, not time.h.
3638 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3639
3640 * dired.c: Include stat-time.h.
3641 (Ffile-attributes): File times now have higher resolution.
3642
3643 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3644 (struct image): Timestamp now has higher resolution.
3645
3646 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3647 has at least microseconds now. All uses removed.
3648 (update_frame, update_single_window, update_window, update_frame_1)
3649 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3650 (duration_to_sec_usec): Remove; no longer needed.
3651
3652 * editfns.c (time_overflow): Now extern.
3653 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3654 (float-time, Fformat_time_string, Fcurrent_time_string)
3655 (Fcurrent_time_zone): Accept and generate higher-resolution
3656 time stamps.
3657 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3658 (decode_time_components, lisp_seconds_argument): New functions.
3659 (make_time): Now static.
3660 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3661 Report an error if the time is invalid, rather than having the caller
3662 do that.
3663
3664 * fileio.c: Include <stat-time.h>
3665 (Fcopy_file): Copy higher-resolution time stamps.
3666 Prefer to set the time stamp via a file descriptor if that works.
3667 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3668 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3669 (Fvisited_file_modtime, Fset_visited_file_modtime):
3670 Support higher-resolution time stamps.
3671
3672 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3673
3674 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3675
3676 * image.c (prepare_image_for_display, clear_image_cache)
3677 (lookup_image): Port to higer-resolution time stamps.
3678
3679 * keyboard.c (start_polling, bind_polling_period):
3680 Check for time stamp overflow.
3681 (read_char, kbd_buffer_get_event, timer_start_idle)
3682 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3683 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3684 Port to higher-resolution time stamps. Do not assume time_t is signed.
3685 (decode_timer): New function. Timers are now vectors of length 9,
3686 not 8, to accommodate the picosecond component.
3687 (timer_check_2): Use it.
3688
3689 * nsterm.m (select_timeout, timeval_subtract): Remove.
3690 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3691 as they're a bit more accurate and handle overflow better.
3692 (ns_select): Change prototype to be compatible with pselect.
3693 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3694 * nsterm.h (ns_select): Adjust prototype.
3695
3696 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3697 us-resolution time stamps.
3698 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3699
3700 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3701
3702 * lisp.h (time_overflow): New decl.
3703 (wait_reading_process_output): First arg is now intmax_t, not int,
3704 to accommodate larger waits.
3705
3706 * process.h (struct Lisp_Process.read_output_delay):
3707 Now counts nanoseconds, not microseconds.
3708 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3709 EMACS_HAS_USECS.
3710 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3711 (wait_reading_process_output):
3712 Port to ns-resolution time stamps.
3713 (Faccept_process_output, wait_reading_process_output):
3714 Check for time stamp overflow. Do not assume time_t is signed.
3715 (select_wrapper): Remove; we now use pselect.
3716 (Fprocess_attributes): Now generates ns-resolution time stamps.
3717
3718 * sysdep.c: Include utimens.h. Don't include utime.h
3719 or worry about struct utimbuf; gnulib does that for us now.
3720 (gettimeofday): Remove; gnulib provides a substitute.
3721 (make_timeval): New function.
3722 (set_file_times): Now sets ns-resolution time stamps.
3723 New arg FD; all uses changed.
3724 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3725 (system_process_attributes):
3726 Now returns ns-resolution time stamp. All uses changed.
3727 Check for time stamp overflow.
3728
3729 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3730 provides a substitute now.
3731
3732 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3733 since it guarantees struct timespec.
3734 (EMACS_TIME): Now struct timespec, so that we can support
3735 ns-resolution time stamps.
3736 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3737 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3738 (EMACS_USECS): Remove.
3739 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3740 so multiply the arg by 1000 before storing it.
3741 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3742 New macros.
3743 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3744 Port to ns-resolution time stamps.
3745 (EMACS_TIME_NEG_P): Remove; replaced by....

3748 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3749 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3750 (make_timeval, make_lisp_time, decode_time_components): New decls.
3751 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3752 that it mishandled time_t overflow. You can't compare by subtracting!
3753 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3754 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3755
3756 * term.c: Include <sys/time.h>.
3757 (timeval_to_Time): New function, for proper overflow wraparound.
3758 (term_mouse_position, term_mouse_click): Use it.
3759
3760 * undo.c (record_first_change): Support higher-resolution time stamps
3761 in the undo buffer.
3762 (Fprimitive_undo): Use them when restoring time stamps.
3763
3764 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3765 (w32_get_internal_run_time):
3766 Port to higher-resolution Emacs time stamps.
3767 (ltime): Now accepts single 64-bit integer, as that's more convenient
3768 for callers.
3769
3770 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3771
3772 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3773 for compatibility with pselect. Support ns-resolution time stamps.
3774
3775 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3776
3777 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3778 Check for time stamp overflow, and support ns-resolution time stamps.
3779
3780 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3781 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3782 (timeval_subtract): Remove; no longer needed.
3783 (XTflash, XTring_bell, x_wait_for_event):
3784 Port to ns-resolution time stamps. Don't assume time_t is signed.
3785

3790 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3791
3792 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3793 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3794 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3795 staticidx goes up to 1597 out of 1600 = 0x640.)
3796
3797 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3798
3799 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3800 Otherwise, the umask might be mistakenly 0 while handling input signals.

3803
3804 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

3810 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3811 access to `contents' member of Lisp_Vector objects with AREF and ASET
3812 where appropriate.
3813
3814 2012-06-19 Chong Yidong <cyd@gnu.org>
3815
3816 * frame.c (delete_frame): When selecting a frame on a different

3820 frame's selected window and its terminal's top-frame.
3821 (unwind_format_mode_line): Restore them.
3822 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3823 Callers changed.
3824 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3825 since tty frames can be explicitly named.
3826 (prepare_menu_bars): Likewise.
3827
3828 * term.c (Ftty_top_frame): New function.
3829
3830 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3831
3832 Port byte-code-meter to modern targets.
3833 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3834 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3835 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3836 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3837 (METER_1, METER_2): Simplify.
3838
3839 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3840
3841 * data.c (Fdefalias): Return `symbol' (bug#11686).
3842
3843 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3844
3845 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3846 gets killed during executing of this function (Bug#11665).
3847 Try to always return Qt when the buffer has been actually killed.
3848 (Vkill_buffer_query_functions): In doc-string say that functions
3849 run by this hook should not change the current buffer.
3850
3851 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3852
3853 Fix recently-introduced process.c problems found by static checking.
3854 * process.c (write_queue_push, write_queue_pop, send_process):
3855 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
3856 (write_queue_pop): Fix pointer signedness problem.
3857 (send_process): Remove unused local.
3858

3871 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3872
3873 * lisp.h (eassert): Assume C89 or later.
3874 This removes the need for CHECK.
3875 (CHECK): Remove. Its comments about always evaluating its
3876 argument were confusing, as 'eassert' typically does not evaluate
3877 its argument.
3878
3879 * coding.c (produce_chars): Use ptrdiff_t, not int.
3880
3881 * xterm.c (x_draw_underwave): Check for integer overflow.
3882 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
3883

3973 2012-06-16 Eli Zaretskii <eliz@gnu.org>
3974
3975 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
3976 If all the glyphs of the glyph row came from strings, and we have no
3977 cursor positioning clues, put the cursor on the first glyph of the
3978 row.
3979 (handle_face_prop): Use chunk-relative overlay string index when
3980 indexing into it->string_overlays array. (Bug#11653)

4008 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
4009 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):
4010 Simplify now that USE_LSB_TAG is always defined.
4011 (TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.
4012 (make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler.

4022
4023 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
4024
4025 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
4026 instead of union.
4027 (XLI, XIL): Define.
4028 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
4029 Use them.

4034 * frame.c (delete_frame): Remove outdated comment.

4064 USE_LSB_TAG now is always defined to be either 0 or 1.
4065 All uses changed.
4066 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
4067 code works fine either way, and efficiency is not a concern here,
4068 as the union type is for debugging, not for production.
4069 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
4070 Use an inline function on all platforms when using the union type,
4071 since this is simpler and 'static inline' can be used portably
4072 within Emacs now.
4073 (LISP_INITIALLY_ZERO): New macro.
4074 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

4155 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
4156
4157 * xdisp.c (vmessage): Treat frame message as multibyte.
4158 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
4159 would generate the diagnostic "Making \302\247 buffer-local while
4160 let-bound!".
4161
4162 2012-06-08 Eli Zaretskii <eliz@gnu.org>

4178 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
4179
4180 2012-06-08 Eli Zaretskii <eliz@gnu.org>
4181
4182 * alloc.c (allocate_vectorlike): Fix last change.

4185
4186 Block-based vector allocation of small vectors.
4187 * lisp.h (struct vectorlike_header): New field `nbytes',
4188 adjust comment accordingly.
4189 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
4190 to denote vector blocks. Adjust users (live_vector_p,
4191 mark_maybe_pointer, valid_lisp_object_p) accordingly.
4192 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
4193 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
4194 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
4195 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),

4213 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
4214
4215 * doprnt.c (doprnt): Truncate multibyte char correctly.
4216 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4217 would mishandle a string argument "Xc" if X was a multibyte
4218 character of length 2: it would truncate after X's first byte
4219 rather than including all of X.
4220
4221 2012-06-06 Chong Yidong <cyd@gnu.org>
4222
4223 * buffer.c (word_wrap): Doc fix.

4236 (temacs$(EXEEXT)): Disable memory randomization for the temacs
4237 binary via PaX flags if the paxctl utility is available.
4238 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):

4246 2012-06-03 Chong Yidong <cyd@gnu.org>
4247
4248 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
4249 (note_mode_line_or_margin_highlight): If there is no help echo,
4250 use mode-line-default-help-echo. Handle the case where the mouse
4251 position is past the end of the mode line string.
4252
4253 * buffer.c (buffer_local_value_1): New function, split from
4254 Fbuffer_local_value; can return Qunbound.

4269
4270 * minibuf.c (Fassoc_string): Remove duplicate declaration.
4271
4272 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
4273 Convert pctcpu and pctmem to Lisp float properly.
4274 Let the compiler fold better, as 100.0/0x8000 is exact.
4275
4276 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
4277
4278 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
4279 cons_block.

4283 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
4284
4285 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
4286
4287 For a 'struct window', replace some Lisp_Object fields to
4288 bitfields where appropriate, remove unused fields.
4289 * window.h (struct window): Remove unused 'last_mark_x' and
4290 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
4291 change it's type from Lisp_Object to bitfield.
4292 Change type of 'force_start', 'optional_new_start',
4293 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
4294 fields from Lisp_Object to bitfield. Adjust users accordingly.
4295
4296 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4297
4298 Pacify gcc -Wdouble-precision when using Xaw.
4299 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
4300 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
4301 Use 'float' consistently, rather than 'float' in most places
4302 and 'double' in a couple of places.
4303
4304 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4305
4306 * xdisp.c (handle_stop): Detect whether we have overlay strings
4307 loaded by testing it->current.overlay_string_index to be
4308 non-negative, instead of checking whether n_overlay_strings is
4309 positive. (Bug#11587)
4310
4311 2012-05-31 Chong Yidong <cyd@gnu.org>
4312
4313 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
4314
4315 * doc.c (Fsubstitute_command_keys): Doc fix.
4316
4317 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4318
4319 * search.c (search_buffer): Remove calls to
4320 r_alloc_inhibit_buffer_relocation, as it is now called by
4321 maybe_unify_char, which was the cause of relocation of buffer text
4322 in bug#11519.
4323
4324 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4325
4326 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4327 for the duration of call to load_charset, to avoid problems with
4328 callers of maybe_unify_char that access buffer text through C
4329 pointers.
4330
4331 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4332 decrement the inhibition flag, instead of just setting or
4333 resetting it.
4334
4335 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4336
4337 Remove obsolete '#define static' cruft.
4338 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
4339 This #undef was "temporary" in 2000; it is no longer needed
4340 now that '#define static' has gone away.
4341 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
4342 (gray_bitmap_bits): Remove; no longer needed.
4343 All uses replaced with definiens.
4344 * xterm.c: Include "bitmaps/gray.xbm".
4345
4346 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4347
4348 Clean up __executable_start, monstartup when --enable-profiling.
4349 The following changes affect the code only when profiling.
4350 * dispnew.c (__executable_start): Rename from safe_bcopy.
4351 Define only on platforms that need it.
4352 * emacs.c: Include <sys/gmon.h> when profiling.
4353 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
4354 (__executable_start): Remove decl, since lisp.h does it now.
4355 (safe_bcopy): Remove decl; no longer has that name.
4356 (main): Coalesce #if into single bit of code, for simplicity.
4357 Cast pointers to uintptr_t, since standard libraries want integers
4358 and not pointers.
4359 * lisp.h (__executable_start): New decl.
4360
4361 2012-05-31 Glenn Morris <rgm@gnu.org>
4362
4363 * image.c (Fimagemagick_types): Doc fix.
4364
4365 2012-05-30 Jim Meyering <meyering@redhat.com>
4366
4367 * callproc.c (Fcall_process_region): Include directory component
4368 in mkstemp error message (Bug#11586).
4369
4370 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4371
4372 * alloc.c, lisp.h (make_pure_vector): Now static.
4373
4374 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
4375
4376 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):

4385
4386 Do not create empty overlays with the evaporate property (Bug#9642).
4387 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4388 Bug#9642, but explicitly check that the buffer the overlay would
4389 be moved to is live and rearrange lines to make sure that errors
4390 will not put the overlay in an inconsistent state.
4391 (Fdelete_overlay): Cosmetics.
4392
4393 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4394
4395 * w32term.c (my_bring_window_to_top): New function.
4396 (x_raise_frame): Use handle returned by DeferWindowPos, which
4397 could be different from the original one.
4398 Call my_bring_window_to_top instead of my_set_foreground_window.
4399 (Bug#11513)
4400
4401 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4402 by calling BringWindowToTop.
4403
4404 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4405 (WM_EMACS_END): Increase by one.
4406
4407 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4408
4409 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4410 This avoids undefined behavior that might cause the eassert
4411 to not catch an out-of-range value.
4412
4413 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4414
4415 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

4425 when referring to sectname field in printf format.
4426
4427 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4428
4429 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4430 Only r_alloc_inhibit_buffer_relocation needed to be added;
4431 the others were already declared.
4432
4433 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4434 before checking whether it's out of range. Put the check inside
4435 eassert. See
4436 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4437
4438 2012-05-27 Ken Brown <kbrown@cornell.edu>
4439
4440 * callproc.c (Fcall_process): Restore a line that was accidentally
4441 commented out in the 2011-02-13 change (bug#11547).
4442
4443 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4444
4445 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4446 defined on ralloc.c.
4447
4448 * buffer.c [REL_ALLOC]: Remove prototypes of
4449 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4450 they are now on lisp.h.
4451
4452 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4453
4454 * search.c (search_buffer): Use it to inhibit relocation of buffer
4455 text while re_search_2 is doing its job, because re_search_2 is
4456 passed C pointers to buffer text. (Bug#11519)
4457
4458 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4459 Update value to 24.
4460
4461 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4462 state after an additional call to move_it_in_display_line_to, keep
4463 the values of it->max_ascent and it->max_descent found for the
4464 entire line.
4465 (pos_visible_p): Revert the comparison against bottom_y to what it
4466 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4467 (Bug#11464)
4468
4469 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4470
4471 Fix coding-related core dumps with gcc -ftrapv.
4472 The code was computing A - B, where A and B are pointers, and B is
4473 random garbage. This can lead to core dumps on platforms that
4474 have special pointer registers, and it also leads to core dumps on
4475 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4476 A - B only when B is initialized properly.
4477 * coding.c (coding_set_source, coding_set_destination): Return void.
4478 (coding_change_source, coding_change_destinations): New functions,
4479 with the old behaviors of coding_set_source and coding_set_destination.
4480 All callers that need an offset changed to use these new functions.
4481
4482 2012-05-26 Glenn Morris <rgm@gnu.org>
4483
4484 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4485
4486 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4487
4488 Extend mouse support on W32 text-mode console.
4489 * xdisp.c (draw_row_with_mouse_face):
4490 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4491
4492 * w32console.c: Include window.h.
4493 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4494 New functions.
4495 (initialize_w32_display): Initialize mouse-highlight data.
4496
4497 * w32inevt.c: Include termchar.h and window.h.
4498 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4499 moves, call note_mouse_highlight. If help_echo changed, call
4500 gen_help_event to produce help-echo message in the echo area.
4501 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4502 highlight info.
4503
4504 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4505
4506 * lread.c (read1): Simplify slightly to avoid an overflow warning
4507 with GCC 4.7.0 on x86-64.
4508
4509 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4510
4511 * bidi.c (bidi_mirror_char): Revert last change: an int is
4512 definitely wide enough here.
4513
4514 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4515
4516 Fix integer width and related bugs (Bug#9874).

4518 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
4519 (string_bytes, check_sblock, allocate_string_data):
4520 (compact_small_strings, Fmake_bool_vector, make_string)
4521 (make_unibyte_string, make_multibyte_string)
4522 (make_string_from_bytes, make_specified_string)

4524 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4525 (mark_vectorlike):
4526 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4527 (allocate_pseudovector):
4528 Use int, not EMACS_INT, where int is wide enough.
4529 (inhibit_garbage_collection, Fgarbage_collect):
4530 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4531 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4532 int might not be wide enough.
4533 (bidi_cache_search, bidi_cache_find, bidi_init_it)
4534 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4535 (bidi_at_paragraph_end, bidi_find_paragraph_start)
4536 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4537 (bidi_level_of_next_char, bidi_move_to_visually_next):
4538 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4539 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4540 (Fkill_buffer, Fset_buffer_major_mode)
4541 (advance_to_char_boundary, Fbuffer_swap_text)
4542 (Fset_buffer_multibyte, overlays_at, overlays_in)
4543 (overlay_touches_p, struct sortvec, record_overlay_string)
4544 (overlay_strings, recenter_overlay_lists)

4548 (Foverlay_recenter, last_overlay_modification_hooks_used)
4549 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4550 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4551 (validate_region): Omit unnecessary test for b <= e,
4552 since that's guaranteed by the previous test.
4553 (adjust_overlays_for_delete): Avoid pos + length overflow.
4554 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4555 (report_overlay_modification):
4556 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4557 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4558 Omit pointer cast, which isn't needed anyway, and doesn't work
4559 after the EMACS_INT -> ptrdiff_t change.
4560 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4561 * buffer.h: Adjust decls to match defn changes elsewhere.

4566 not int, to avoid needless 32-bit limit on 64-bit hosts.
4567 (exec_byte_code): Use tighter memory-full test, one that checks
4568 for alloca overflow. Don't compute the address of the object just
4569 before an array, as that's not portable. Use EMACS_INT, not
4570 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4571 * callint.c (Fcall_interactively):
4572 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4573 * callproc.c (call_process_kill, Fcall_process):

4584 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4585 (casify_object): Avoid integer overflow when overallocating buffer.
4586 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

4589 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4590 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4591 integers are now checked earlier. All uses replaced with XINT.
4592 (ccl_driver):
4593 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4594 For CCL_MapSingle, check that content and value are in int range.
4595 (ccl_driver, Fregister_code_conversion_map):
4596 Check that Vcode_version_map_vector is a vector.
4597 (resolve_symbol_ccl_program): Check that vector header is in range.
4598 Always copy the vector, so that we can check its contents reliably
4599 now rather than having to recheck each instruction as it's being
4600 executed. Check that vector words fit in 'int'.
4601 (ccl_get_compiled_code, Fregister_ccl_program)
4602 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4603 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4604 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4605 contents are in range.
4606 (Fccl_execute_on_string): Check that status is in range.
4607 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4608 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4609 Accept and return EMACS_INT, not int, because callers can pass values
4610 out of 'int' range.

4616 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4617 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4618 avoid mishandling large integers.

4629 Don't rely on undefined behavior with signed left shift overflow.
4630 Don't assume unsigned int fits into fixnum, or that fixnum fits
4631 into unsigned int. Don't require max_code to be a valid fixnum;
4632 that's not true for gb10830 4-byte on a 32-bit host. Allow
4633 invalid_code to be a cons, for the same reason. Require code_offset
4634 to be a character. Avoid int overflow if max_char is close
4635 to INT_MAX.
4636 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4637 this is intended anyway and avoids some undefined behavior.
4638 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4639 INDEX_TO_CODE_POINT, as that's what it expects.
4640 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4641 * charset.h (DECODE_CHAR): Return int, not unsigned;
4642 this is what was intended anyway, and it avoids undefined behavior.
4643 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4644 integer-overflow issues.
4645 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4646 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4647 where the argument is EMACS_INT, and this behavior is not intended.
4648 * chartab.c (Fmake_char_table, Fset_char_table_range)
4649 (uniprop_get_decoder, uniprop_get_encoder):
4650 Don't assume fixnum fits in int.
4651 * cmds.c (move_point): New function, that does the gist of
4652 Fforward_char and Fbackward_char, but does so while checking
4653 for integer overflow more accurately.
4654 (Fforward_char, Fbackward_char): Use it.
4655 (Fforward_line, Fend_of_line, internal_self_insert)
4656 (internal_self_insert):
4657 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

5305 Don't assume EMACS_INT overflows nicely into int.
5306 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
5307 may come from Lisp.
5308 (handle_one_xevent): NATNUMP can eval its arg twice.
5309 (x_connection_closed):

5315
5316 2012-05-25 Glenn Morris <rgm@gnu.org>
5317
5318 * lisp.mk (lisp): Update for more files being compiled now.
5319
5320 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
5321
5322 * lread.c: Remove `read_pure' which makes no difference.
5323 (read_pure): Remove var.
5324 (unreadpure): Remove function.
5325 (readevalloop): Don't call read_list with -1 flag.
5326 (read1, read_vector): Don't test read_pure any more.
5327 (read_list): Simplify.
5328
5329 * fileio.c, character.h: Minor style tweaks.
5330
5331 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
5332
5333 * window.h (clip_changed): Remove useless declaration.
5334
5335 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
5336
5337 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
5338 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
5339
5340 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
5341
5342 Remove src/m/*.
5343 This directory predates autoconf and is no longer needed nowadays.
5344 Move its few remaining bits of functionality to where they're needed.
5345 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
5346 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
5347 * m/template.h: Remove.
5348 * Makefile.in (M_FILE): Remove. All uses removed.
5349 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
5350 * lisp.h (USE_LSB_TAG):
5351 * mem-limits.h (EXCEEDS_LISP_PTR):
5352 Use VAL_MAX, not VALBITS, in #if.
5353 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
5354 (EMACS_UINT): Define unconditionally now.
5355 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
5356 (BITS_PER_EMACS_INT): New constants, replacing
5357 what used to be in config.h, but not useful in #if.
5358 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
5359 define them any more.
5360 (VAL_MAX): New macro.
5361 (VALMASK): Use it.
5362 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
5363 BITS_PER_EMACS_INT, in #if.
5364 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
5365 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.

5367 * s/ms-w32.h (DATA_START):
5368 Move here from removed file m/intel386.h.
5369 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
5370 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
5371
5372 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
5373
5374 Assume C89 or later.
5375 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
5376 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
5377 (xrealloc):
5378 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
5379 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
5380 * textprop.c, tparam.c (NULL): Remove.
5381 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
5382 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
5383 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
5384 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
5385 * xterm.c (input_signal_count): Assume volatile works.
5386
5387 2012-05-21 Ken Brown <kbrown@cornell.edu>
5388
5389 * xgselect.c (xg_select): Fix first argument in call to 'select'
5390 (bug#11508).
5391
5392 2012-05-20 Ken Brown <kbrown@cornell.edu>
5393
5394 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
5395 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
5396
5397 2012-05-19 Ken Brown <kbrown@cornell.edu>
5398
5399 * xfns.c (x_in_use): Remove `static' qualifier.
5400 * xterm.h (x_in_use): Declare.
5401 * xgselect.c: Include xterm.h.
5402 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
5403 and `display_arg' (bug#9754).
5404
5405 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
5406
5407 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
5408
5409 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
5410 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
5411
5412 2012-05-18 Eli Zaretskii <eliz@gnu.org>
5413
5414 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
5415
5416 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
5417 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
5418
5419 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
5420 reference to image_cache->refcount.
5421 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
5422
5423 2012-05-17 Juri Linkov <juri@jurta.org>
5424
5425 * search.c (Fword_search_regexp, Fword_search_backward)
5426 (Fword_search_forward, Fword_search_backward_lax)
5427 (Fword_search_forward_lax): Move functions to isearch.el
5428 (bug#10145, bug#11381).
5429
5430 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
5431
5432 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
5433
5434 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
5435
5436 * lread.c (init_obarray): Declare Qt and Qnil as special.
5437
5438 2012-05-14 Glenn Morris <rgm@gnu.org>
5439
5440 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
5441 Put "libexec" before "bin", for the sake of init_callproc_1.
5442
5443 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5444
5445 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
5446
5447 * unexaix.c: Port to more-recent AIX compilers.
5448 (report_error, report_error_1, make_hdr, copy_sym)
5449 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
5450 Make arguments const char *, not char *, to avoid violations of C
5451 standard and to fix some AIX warnings reported by Gilles Pion.
5452
5453 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5454
5455 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
5456 already have overlays loaded.
5457 (handle_single_display_spec): Before returning without displaying
5458 fringe bitmap, synchronize the bidi iterator with the main display
5459 iterator, by calling iterate_out_of_display_property.
5460 (iterate_out_of_display_property): Detect buffer iteration by
5461 testing that it->string is a Lisp string.
5462 (get_next_display_element): When the current object is exhausted,
5463 and there's something on it->stack, call set_iterator_to_next to
5464 proceed with what's on the stack, instead of returning zero.
5465 (set_iterator_to_next): If called at the end of a Lisp string,
5466 proceed to consider_string_end without incrementing string
5467 position. Don't increment display vector index past the end of
5468 the display vector. (Bug#11417)
5469 (pos_visible_p): Don't report a position visible when move_it_to
5470 stopped at the last line of window, which happens to be scanned
5471 backwards by the bidi iteration. (Bug#11464)
5472
5473 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5474
5475 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5476 and right-margin display specs even if the spec is invalid or we
5477 are on a TTY, and thus unable to display on the fringes.
5478 That's because the text with the property will not be displayed anyway,
5479 so we need to signal to the caller that this is a "replacing"
5480 display spec. This fixes display when the spec is invalid or we
5481 are on a TTY.
5482
5483 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5484
5485 * unexaix.c (make_hdr): Fix typo in prototype.
5486 This bug broke the build on AIX. Problem reported by Gilles Pion.
5487
5488 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5489
5490 * keyboard.c (kbd_buffer_get_event): Read special events also in
5491 batch mode. (Bug#11415)
5492
5493 2012-05-12 Glenn Morris <rgm@gnu.org>
5494
5495 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5496
5497 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5498
5499 * lisp.mk (lisp): Add newcomment.elc.
5500
5501 2012-05-12 Glenn Morris <rgm@gnu.org>
5502
5503 * Makefile.in (MKDIR_P): New, set by configure.
5504 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5505
5506 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5507
5508 Remove unused function hourglass_started.
5509 * dispextern.h (hourglass_started):
5510 * w32fns.c (hourglass_started):
5511 * xdisp.c (hourglass_started): Remove.
5512
5513 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5514
5515 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5516 Update dependencies.
5517
5518 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5519
5520 * xgselect.c (xg_select): Put maxfds+1 into a var.
5521 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5522
5523 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5524
5525 2012-05-10 Dave Abrahams <dave@boostpro.com>
5526
5527 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5528 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5529
5530 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5531
5532 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5533 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5534 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5535 Initialize xd_registered_buses.
5536
5537 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5538
5539 Untag more efficiently if USE_LSB_TAG.
5540 This is based on a proposal by YAMAMOTO Mitsuharu in
5541 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5542 For an admittedly artificial (nth 8000 longlist) benchmark on
5543 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5544 Emacs's overall text size by 1%.
5545 * lisp.h (XUNTAG): New macro.
5546 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5547 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5548 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5549 * eval.c (Fautoload):
5550 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5551 * frame.h (XFRAME): Use XUNTAG.
5552
5553 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5554 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5555 Remove unportable assumptions about print widths of types like
5556 dbus_uint32_t.
5557 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5558 intptr_t when converting between pointer and integer, to avoid GCC
5559 warnings about wrong width.
5560
5561 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5562
5563 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5564 stack for each reader_thread, instead of defaulting to 8MB
5565 determined by the linker. This avoids failures in creating
5566 subprocesses on Windows 7, see the discussion in this thread:
5567 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5568
5569 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5570
5571 Fix up display of the *Minibuf-0* buffer in the mini window.
5572 * keyboard.c (read_char): Don't clear the echo area if there's no
5573 message to clear.
5574 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5575 contents of *Minibuf-0*) if there's no message displayed in its stead.
5576
5577 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5578
5579 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5580 batch mode.
5581
5582 2012-05-06 Chong Yidong <cyd@gnu.org>
5583
5584 * lisp.mk (lisp): Update.
5585
5586 2012-05-05 Jim Meyering <meyering@redhat.com>
5587
5588 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5589
5590 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5591
5592 * data.c (PUT_ERROR): New macro.
5593 (syms_of_data): Use it. Add new error type `user-error'.
5594 * undo.c (user_error): New function.
5595 (Fprimitive_undo): Use it.
5596 * print.c (print_error_message): Adjust print style for `user-error'.
5597 * keyboard.c (user_error): New function.
5598 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5599
5600 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5601
5602 Do not limit current-time-string to years 1000..9999.
5603 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5604 (Fcurrent_time_string): Support any year that is supported by the
5605 underlying localtime representation. Don't use asctime, as it
5606 has undefined behavior for years outside the range -999..9999.
5607
5608 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5609
5610 Fix race conditions involving setenv, gmtime, localtime, asctime.
5611 Without this fix, interrupts could mess up code that uses these
5612 nonreentrant functions, since setting TZ invalidates existing
5613 tm_zone or tzname values, and since most of these functions return
5614 pointers to static storage.
5615 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5616 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5617 Grow the critical sections to include not just invoking
5618 localtime/gmtime, but also accessing these functions' results
5619 including their tm_zone values if any, and any related TZ setting.
5620 (format_time_string): Last arg is now struct tm *, not struct tm **,
5621 so that the struct tm is saved in the critical section.
5622 All callers changed. Simplify allocation of initial buffer, partly
5623 motivated by the fact that memory allocation needs to be outside
5624 the critical section.
5625

5639
5640 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5641
5642 * xdisp.c (pos_visible_p): If already at a newline from the
5643 display string before the 'while' loop, don't walk back the glyphs
5644 from it3.glyph_row. Solves assertion violation when the display
5645 string begins with a newline (egg.el). (Bug#11367)
5646
5647 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5648
5649 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):

5654 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5655 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5656 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5657 All were removed before 23.1.
5658
5659 * dispnew.c: Remove HAVE_LIBNCURSES test;
5660 it is always true on relevant platforms.

5674
5675 Do not avoid creating empty evaporating overlays (Bug#9642).
5676 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5677 That is, do not delete an evaporating overlay if it becomes
5678 empty after its bounds are adjusted to fit within its buffer.
5679 This fix caused other problems, and I'm reverting it until we get
5680 to the bottom of them.
5681

5688 * xdisp.c (pos_visible_p): If the window start position is beyond
5689 ZV, start the display from buffer beginning. Prevents assertion
5690 violation in init_iterator when the minibuffer window is scrolled
5691 via the scroll bar.
5692
5693 * window.c (window_scroll_pixel_based): Likewise.
5694
5695 2012-04-27 Chong Yidong <cyd@gnu.org>

5708
5709 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5710
5711 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5712 display element, check also the underlying string or buffer
5713 character. (Bug#11341)
5714
5715 * w32menu.c: Include w32heap.h.
5716 (add_menu_item): If the call to AppendMenuW (via
5717 unicode_append_menu) fails, disable Unicode menus only if we are
5718 running on Windows 9X/Me.
5719
5720 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5721

5723 (xgetint): Add missing shift for LSB tags.
5724
5725 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5726
5727 * keyboard.c (read_char): Don't wipe echo area for select window
5728 events: These might get delayed via `mouse-autoselect-window'
5729 (Bug#11304).
5730
5731 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5732

5734 manipulation of :loaded-from data.
5735
5736 2012-04-23 Juanma Barranquero <lekktu@gmail.com>

5738 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5739 now a cons (bug#11311).
5740
5741 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5742
5743 Do not create empty overlays with the evaporate property (Bug#9642).
5744 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5745 if it becomes empty after its bounds are adjusted to fit within
5746 its buffer. Without this fix, in a nonempty buffer (let ((o
5747 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5748 yields an empty overlay that has the evaporate property, which is
5749 not supposed to happen.
5750
5751 Fix minor GTK3 problems found by static checking.
5752 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

5772 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5773 (__malloc_size_t, __malloc_ptrdiff_t):

5880 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
5881
5882 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
5883 It is never used otherwise.
5884
5885 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>

5887 * print.c (print_preprocess): Only check print_depth if print-circle
5888 is nil.
5889 (print_object): Check for cycles even when print-circle is nil and
5890 print-gensym is t, but only check print_depth if print-circle is nil.
5891
5892 2012-04-20 Chong Yidong <cyd@gnu.org>
5893
5894 * process.c (wait_reading_process_output): If EIO occurs on a pty,

5903 2012-04-20 Eli Zaretskii <eliz@gnu.org>
5904
5905 * xdisp.c (string_buffer_position_lim): Limit starting position to
5906 BEGV.

5954 (NEED_MEM_INSERT): New macro.
5955 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5956 Remove one incorrect comment and fix another.

5992 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5993 * s/netbsd.h, s/sol2-6.h:
5994 Remove definition of GC_MARK_STACK, since the default now works.
5995 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5996 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's

6022
6023 2012-04-11 Daniel Colascione <dancol@dancol.org>
6024
6025 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
6026 against is gone. It's better to use vfork now so that when Cygwin

6042
6043 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
6044 (force_quit_count): New var.

6052 2012-04-09 Glenn Morris <rgm@gnu.org>
6053
6054 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
6055 not just in the obarray, before snarfing them. (Bug#11036)
6056
6057 * Makefile.in ($(leimdir)/leim-list.el):
6058 Pass EMACS rather than BUILT_EMACS.
6059
6060 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
6061
6062 * process.c (make_process):
6063 * process.h: Add integer `gnutls_handshakes_tried' member to
6064 process struct.
6065
6066 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
6067 Add convenience `GNUTLS_LOG2i' macro.
6068
6069 * gnutls.c (gnutls_log_function2i): Convenience log function.
6070 (emacs_gnutls_read): Use new log functions,
6071 `gnutls_handshakes_tried' process member, and
6072 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
6073 attempts per process (connection).
6074
6075 2012-04-09 Chong Yidong <cyd@gnu.org>
6076
6077 * eval.c (Fuser_variable_p, user_variable_p_eh)

6083
6084 2012-04-09 Eli Zaretskii <eliz@gnu.org>
6085
6086 * xdisp.c (set_cursor_from_row): If the display string appears in
6087 the buffer at position that is closer to point than the position
6088 after the display string, display the cursor on the first glyph of
6089 the display string. Fixes cursor display when a 'display' text
6090 property immediately follows invisible text. (Bug#11094)
6091
6092 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
6093
6094 composite.c: use 'double' consistently
6095 * composite.c (get_composition_id): Use 'double' consistently
6096 instead of converting 'float' to 'double' and vice versa; this is
6097 easier to understand and avoids a GCC warning.
6098
6099 2012-04-09 Glenn Morris <rgm@gnu.org>
6100
6101 * Makefile.in: Generate leim-list with bootstrap-emacs, in

6110
6111 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
6112
6113 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
6114 proper alignment.
6115
6116 2012-04-07 Juanma Barranquero <lekktu@gmail.com>

6121 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
6122
6123 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
6124 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
6125 (mark_memory): Mark Lisp_Objects only if pointers might hide in
6126 objects, as mark_maybe_pointer will catch them otherwise.
6127 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
6128 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
6129
6130 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
6131
6132 Fix typo that broke non-Windows builds.
6133 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
6134
6135 2012-04-07 Eli Zaretskii <eliz@gnu.org>
6136
6137 Support building on MS-Windows with libxml2.
6138

6145 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
6146 [!WINDOWSNT]: New macros.
6147 (init_libxml2_functions, libxml2_loaded_p): New functions.
6148 (parse_region): Call fn_xmlCheckVersion instead of using the macro
6149 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
6150 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
6151 Calls xmlCleanupParser only if libxml2 was loaded (or statically
6152 linked in).
6153 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
6154 Call init_libxml2_functions before calling libxml2 functions.
6155 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
6156
6157 * emacs.c: Don't include libxml/parser.h.
6158 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
6159 xmlCleanupParser directly.
6160
6161 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
6162
6163 2012-04-07 Eli Zaretskii <eliz@gnu.org>
6164
6165 * indent.c (Fvertical_motion): If there is a display string at
6166 point, use it.vpos to compute how many lines to backtrack after
6167 move_it_to point. (Bug#11133)
6168
6169 2012-04-06 Eli Zaretskii <eliz@gnu.org>
6170
6171 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
6172 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
6173 about subtle differences between FETCH_CHAR* and STRING_CHAR*
6174 macros related to unification of CJK characters. For the details,
6175 see the discussion following the message here:
6176 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
6177
6178 2012-04-04 Chong Yidong <cyd@gnu.org>

6180 * keyboard.c (Vdelayed_warnings_list): Doc fix.
6181
6182 2012-04-01 Eli Zaretskii <eliz@gnu.org>

6188
6189 * w32menu.c (is_simple_dialog): Properly check lisp types.
6190 (Bug#11141)
6191
6192 2012-03-31 Eli Zaretskii <eliz@gnu.org>
6193
6194 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
6195 position we get to after a call to move_it_to fails the
6196 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
6197 only if we wind up in a string from display property. (Bug#11063)
6198
6199 * window.c (Fdelete_other_windows_internal): Invalidate the row
6200 and column information about mouse highlight, so that redisplay
6201 restores it after reallocating the glyph matrices. (Bug#7464)
6202
6203 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
6204 string comes from a `display' text property, use the buffer
6205 position of that property as if we actually saw that position in
6206 the row's glyphs.
6207 (move_it_by_lines): Remove the assertion that
6208 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6209 violated when there's a before-string at the beginning of a line.
6210 (Bug#11063)
6211
6212 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6213
6214 * xdisp.c (append_space_for_newline): If the default face was
6215 remapped, use the remapped face for the appended newline.
6216 (extend_face_to_end_of_line): Use the remapped default face for
6217 extending the face to the end of the line.
6218 (display_line): Call extend_face_to_end_of_line when the default
6219 face was remapped. (Bug#11068)
6220
6221 2012-03-29 Eli Zaretskii <eliz@gnu.org>
6222
6223 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
6224
6225 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
6226
6227 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
6228
6229 2012-03-27 Glenn Morris <rgm@gnu.org>
6230
6231 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
6232 Doc fixes.
6233
6234 2012-03-26 Kenichi Handa <handa@m17n.org>
6235
6236 * dispextern.h (struct glyph): Fix previous change. Change the
6237 bit length of glyphless.ch to 25 (Bug#11082).
6238
6239 2012-03-26 Chong Yidong <cyd@gnu.org>
6240
6241 * keyboard.c (Vselection_inhibit_update_commands): New variable.
6242 (command_loop_1): Use it; inhibit selection update for
6243 handle-select-window too (Bug#8996).
6244
6245 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
6246
6247 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
6248
6249 2012-03-25 Kenichi Handa <handa@m17n.org>
6250
6251 * dispextern.h (struct glyph): Change the bit length of
6252 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6253
6254 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6255
6256 * s/ms-w32.h (tzname): Include time.h before redirecting to
6257 _tzname. Fixes the MSVC build. (Bug#9960)

6259 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
6260
6261 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6262 characters.
6263
6264 * xterm.c (XTread_socket): Only modify handling_signal if
6265 !SYNC_INPUT. (Bug#11080)
6266
6267 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6268
6269 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6270 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6271 when fetching a multibyte character consumes more bytes than
6272 CHAR_BYTES returns, due to unification of CJK characters in
6273 string_char. (Bug#11073)
6274
6275 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6276
6277 * process.c (wait_reading_process_output): Handle pty disconnect
6278 by refraining from sending oneself a SIGCHLD (bug#10933).
6279
6280 2012-03-22 Chong Yidong <cyd@gnu.org>
6281
6282 * dispextern.h (struct it): New member string_from_prefix_prop_p.
6283
6284 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
6285 Mark string as coming from a prefix property.
6286 (handle_face_prop): Use default face for prefix strings (Bug#4281).
6287 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
6288
6289 2012-03-21 Chong Yidong <cyd@gnu.org>
6290
6291 * xfaces.c (Vface_remapping_alist): Doc fix.
6292
6293 2012-03-20 Eli Zaretskii <eliz@gnu.org>
6294
6295 * w32proc.c (Fw32_set_console_codepage)
6296 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
6297 Doc fixes.
6298
6299 2012-03-20 Chong Yidong <cyd@gnu.org>
6300
6301 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
6302 to reflect default non-nil value of redisplay-dont-pause.
6303
6304 2012-03-19 Kenichi Handa <handa@m17n.org>
6305
6306 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
6307 it fit in a valid range (Bug#11003).
6308
6309 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6310
6311 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6312 that is not from display property, accept the row as a "cursor
6313 row" if one of the string's character has a non-nil `cursor'
6314 property. Fixes cursor positioning when there are newlines in
6315 overlay strings, e.g. in icomplete.el. (Bug#11035)
6316
6317 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6318
6319 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
6320
6321 2012-03-12 Chong Yidong <cyd@gnu.org>
6322
6323 * eval.c (inhibit_lisp_code): Rename from
6324 inhibit_window_configuration_change_hook; move from window.c.
6325
6326 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6327 * window.c (run_window_configuration_change_hook)
6328 (syms_of_window): Callers changed.
6329
6330 2012-03-11 Chong Yidong <cyd@gnu.org>
6331
6332 * keymap.c (Fkey_description): Doc fix (Bug#9700).
6333
6334 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
6335
6336 2012-03-10 Chong Yidong <cyd@gnu.org>
6337
6338 * frame.c (other_visible_frames): Don't assume the selected frame
6339 is visible (Bug#10955).

6342
6343 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6344
6345 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6346
6347 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6348 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6349 zero (Bug#10954).
6350
6351 2012-03-03 Glenn Morris <rgm@gnu.org>
6352
6353 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6354
6355 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6356
6357 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6358 position past the first glyph_row that ends at ZV. (Bug#10902)
6359 (redisplay_window, next_element_from_string): Fix typos in
6360 comments.
6361 (redisplay_window): Pass to move_it_vertically the margin in
6362 pixels, not in screen lines.
6363
6364 2012-03-02 Glenn Morris <rgm@gnu.org>
6365
6366 * buffer.c (buffer-list-update-hook): Doc fix.
6367
6368 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6369
6370 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6371 push_it before setting up the iterator for the first overlay
6372 string, even if we have an empty string loaded.
6373 (next_overlay_string): If there's an empty string on the iterator
6374 stack, pop the stack. (Bug#10903)
6375
6376 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6377
6378 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6379 Suggested by Stefan Monnier in
6380 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6381 * alloc.c (widen_to_Lisp_Object): New static function.
6382 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6383 and widening them to Lisp_Objects. This would work even if
6384 USE_LSB_TAG is defined and wide integers are used, which might
6385 happen in a future version of Emacs.
6386
6387 2012-02-25 Chong Yidong <cyd@gnu.org>
6388
6389 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6390 Doc fix.
6391
6392 * xselect.c (Fx_selection_exists_p): Doc fix.
6393 (x_clipboard_manager_save_all): Print an informative message
6394 before saving to clipboard manager.
6395
6396 2012-02-24 Chong Yidong <cyd@gnu.org>
6397
6398 * keyboard.c (process_special_events): Handle all X selection
6399 requests in kbd_buffer, not just the next one (Bug#8869).
6400
6401 2012-02-23 Chong Yidong <cyd@gnu.org>
6402
6403 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
6404 call when setting menu-bar-lines and tool-bar-lines parameters.
6405 (unwind_create_frame_1): New helper function.
6406
6407 * window.c (inhibit_window_configuration_change_hook): New var.
6408 (run_window_configuration_change_hook): Obey it.
6409 (syms_of_window): Initialize it.
6410
6411 2012-02-22 Chong Yidong <cyd@gnu.org>
6412
6413 * xterm.c (x_draw_image_relief): Add missing type check for
6414 Vtool_bar_button_margin (Bug#10743).
6415
6416 2012-02-21 Chong Yidong <cyd@gnu.org>
6417
6418 * fileio.c (Vfile_name_handler_alist): Doc fix.
6419
6420 * buffer.c (Fget_file_buffer): Protect against invalid file
6421 handler return value.
6422
6423 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
6424
6425 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
6426 when computing $valmask.
6427
6428 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6429 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6430 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6431 It's useless in that case, and it can cause problems on hosts
6432 that allocate halves of EMACS_INT values separately.
6433 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6434 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6435 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6436 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6437 it avoids undefined behavior on hosts where shifting right by more
6438 than the word width has undefined behavior.
6439
6440 2012-02-19 Chong Yidong <cyd@gnu.org>
6441
6442 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

6446 return values (Bug#10845).
6447
6448 2012-02-18 Eli Zaretskii <eliz@gnu.org>
6449
6450 * .gdbinit (pitx): Fix incorrect references to fields of the
6451 iterator stack.
6452
6453 2012-02-17 Chong Yidong <cyd@gnu.org>

7068
7069 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>

7218 Otherwise, valgrind does not work on some platforms.
7219 Problem reported by Andreas Schwab in
7220 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
7221 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
7222 is set, removing the need for VIRT_ADDRESS_VARIES.
7223 (PURE_P): Use a more-efficient implementation that needs just one
7224 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
7225 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
7226 to 4 (xorl, subq, cmpq, setbe).
7227 * alloc.c (pure): Always extern now, since that's the
7228 VIRT_ADDR_VARIES behavior.
7229 (PURE_POINTER_P): Use a single comparison, not two, for
7230 consistency with the new puresize.h.
7231 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
7232 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

7238 (erase_phys_cursor, update_window_cursor, show_mouse_face)
7239 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
7240 behave as if the cursor position were at the window margin.
7241
7242 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7243 and the cursor position is out of bounds, behave as if the cursor
7244 position were at the window margin. (Bug#10075)
7245
7246 2011-11-18 Chong Yidong <cyd@gnu.org>
7247
7248 * window.c (Fwindow_combination_limit): Make first argument

7266 hash values of the two rows. (Bug#10035)
7267 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
7268
7269 * xdisp.c (row_hash): New function, body extracted from
7270 compute_line_metrics.
7271 (compute_line_metrics): Call row_hash, instead of computing the
7272 hash code inline.
7273
7274 * dispnew.c (verify_row_hash): Call row_hash for computing the
7275 hash code of a row, instead of duplicating code from xdisp.c.
7276

7316
7317 * xdisp.c (display_line): Move the call to
7318 highlight_trailing_whitespace before the call to
7319 compute_line_metrics, since the latter needs to see the final
7320 faces of all the glyphs to compute ROW's hash value.
7321 Fixes assertion violations in row_equal_p. (Bug#10035)
7322
7323 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

7334
7335 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

7416
7417 * w32.c (check_windows_init_file): Don't look for term/w32-win.el

7462 (window_box_width, window_box_left, window_box_left_offset)
7463 (window_box_right, window_box_right_offset): Declare extern.
7464 Otherwise, these inline functions do not conform to C99 and
7465 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7466 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7467 * intervals.c (adjust_intervals_for_insertion)

7470 (static_offset_intervals): Remove.
7471 (offset_intervals): Rewrite using the old contents of
7472 static_offset_intervals. The old version didn't conform to C99
7473 because an extern inline function contained a reference to an
7474 identifier with static linkage.

7496 (Fwindow_vscroll): Doc fix.

7498 argument, since it makes no sense to pass a live window and for
7499 consistency with window-child.

7724 2011-10-27 Chong Yidong <cyd@gnu.org>
7725
7726 * process.c (make_process): Set gnutls_state to NULL.
7727
7728 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
7729 non-NULL, regardless of GNUTLS_INITSTAGE.
7730 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7731 an error. Set process slots as soon as we allocate them.
7732
7733 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
7734
7735 2011-10-27 Chong Yidong <cyd@gnu.org>
7736
7737 * gnutls.c (emacs_gnutls_deinit): New function.
7738 Deallocate credentials structures as well as calling gnutls_deinit.
7739 (Fgnutls_deinit, Fgnutls_boot): Use it.
7740
7741 * process.c (make_process): Initialize GnuTLS credentials to NULL.
7742 (deactivate_process): Call emacs_gnutls_deinit.

7754 extracted from Fw32_default_color_map.
7755 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
7756
7757 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
7758
7759 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
7760
7761 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
7762

7769 terminal (Bug#6649).
7770
7771 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7772
7773 * dispextern.h (struct bidi_it): New member next_en_type.
7774
7775 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7776 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7777 current character, check also for next_en_type being WEAK_EN.
7778 (bidi_resolve_weak): Don't enter the expensive loop if the current
7779 position is before next_en_pos. Record the bidi type of the first
7780 non-ET, non-BN character we find, in addition to its position.
7781 (bidi_level_of_next_char): Invalidate next_en_type when
7782 next_en_pos is over-stepped.
7783
7784 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7785
7786 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7787 * editfns.c: Rewrite current-time-zone so that it invokes
7788 the equivalent of (format-time-string "%Z") to get the time zone name.
7789 This fixes a bug when the time zone name contains characters that
7790 need converting from the system time locale to Emacs internal format.
7791 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7792 that patch fixed format-time-string to do the conversion, but
7793 I forgot to fix current-time-zone.
7794 (format_time_string): New function, containing most of
7795 what Fformat_time_string used to contain.
7796 (Fformat_time_string): Rewrite in terms of format_time_string.
7797 This doesn't change this function's behavior.
7798 (current-time-zone): Rewrite to use format_time_string.
7799 This fixes the bug reported by Michael Schierl in
7800 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7801 Jason Rumney's 2007-06-07 change worked around this bug, but
7802 didn't fix it.
7803 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7804
7805 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7806
7807 * xdisp.c (start_display): If the character at POS is displayed
7808 via a display vector, reset IT->current.dpvec_index to zero.
7809 (try_window_reusing_current_matrix): If a line ends in a display
7810 vector or the next line starts in a display vector, continue
7811 redrawing the window even though the character position of
7812 start_row was reached.
7813 (Bug#9771, part 2)
7814
7815 2011-10-18 Chong Yidong <cyd@gnu.org>
7816
7817 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7818 with nobreak-char-display too.
7819
7820 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7821
7822 Fix part 3 of bug#9771.
7823 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7824 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7825 non-neutral characters if the current character is a paragraph
7826 separator (a.k.a. Newline). This avoids running the same
7827 expensive loop twice, once when we consume the preceding newline
7828 and the other time when the line actually needs to be displayed.
7829 Avoid the loop when we see neutrals on the base embedding level
7830 following a character whose directionality is the same as the
7831 paragraph's. This avoids running the expensive loop when a line
7832 ends in a long sequence of neutrals, like control characters.
7833 Add assertion against STRONG_AL type. Slightly rearrange code
7834 that determines the type of a neutral given the first non-neutral
7835 that follows it.
7836 (bidi_level_of_next_char): Set next_en_pos to zero when
7837 invalidating its info.
7838
7839 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7840
7841 * xdisp.c (push_display_prop): Determine whether to record string
7842 or buffer position by IT->string, not by IT->method. Allow
7843 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7844 (move_it_vertically_backward): Don't look for character position
7845 immediately after the newline when in a continuation line.
7846 (Bug#9771, part 1)
7847
7848 2011-10-15 Martin Rudalics <rudalics@gmx.at>

7857
7858 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7859
7860 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7861 avoid crash when xmalloc overrun checking is enabled.
7862
7863 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7864
7865 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7866 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7867 cursor motion with <left> and <right> arrow keys.
7868
7869 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7870 some callers set that themselves.
7871
7872 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7873
7874 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7875 display string and the previous row comes from the same string and
7876 is empty. (Bug#9739) (Bug#9738)
7877
7878 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>

7883
7884 * bidi.c (bidi_level_of_next_char):
7885 * xdisp.c (get_visually_first_element): Remove old incorrect
7886 comments regarding the Unicode Line Separator character.
7887
7888 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7889
7890 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7891
7892 * alloc.c (Fgc_status): Do not access beyond zombies array
7893 boundary if nzombies > MAX_ZOMBIES.
7894 * alloc.c (dump_zombies): Add missing format specifier.
7895
7896 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7897
7898 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7899 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7900
7901 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7902 Some packages use them to denote characters with modifiers.
7903
7904 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7905
7906 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7907 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7908 matching a pp-number. Rename parameter var to var1.
7909
7910 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7911
7912 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7913
7914 2011-10-08 Glenn Morris <rgm@gnu.org>
7915
7916 * callint.c (Fcall_interactively): Give a more explicit error for the
7917 'c' case with a non-character input. (Bug#8479)
7918
7919 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7920
7921 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7922 lines.
7923 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7924 lines that are hscrolled on the left.
7925
7926 * dispnew.c (buffer_posn_from_coords): Account for a possible
7927 presence of header-line. (Bug#4426)
7928
7929 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7930
7931 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7932 Don't advertise functionality which we discourage or doesn't work.
7933
7934 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7935
7936 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7937 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7938 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7939 this makes Emacs dump core during garbage collection on rare
7940 occasions. sizeof is obviously inferior to offsetof here, so
7941 stick with offsetof.
7942 (GC_POINTER_ALIGNMENT): New macro.
7943 (mark_memory): Omit 3rd (offset) arg; caller changed.
7944 Don't assume EMACS_INT alignment is the same as pointer alignment.
7945
7946 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7947
7948 * keyboard.c (read_key_sequence_remapped): New var.
7949 (read_key_sequence): Compute remapping in the right buffer.
7950 (command_loop_1): Use read_key_sequence's remapping directly.
7951
7952 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7953
7954 * dired.c (file_name_completion): Don't expand file name.
7955 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7956 before checking file name handler.
7957
7958 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7959 they've been requested explicitly (bug#9591).
7960
7961 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7962
7963 * keymap.c (Fsingle_key_description): Use make_specified_string
7964 instead of build_string to build string from push_key_description.
7965 (Bug#5193)
7966
7967 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7968
7969 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7970 This fixes a Y2038 bug on 64-bit hosts.
7971 * buffer.c (reset_buffer):
7972 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7973 (Fclear_buffer_auto_save_failure):
7974 Use 0, not -1, to represent an unset failure time, since time_t
7975 might not be signed.
7976
7977 Remove dependency on glibc malloc internals.
7978 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7979 Move back here from lisp.h, but with their new implementations.
7980 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7981 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7982 * charset.c (charset_table_init): New static var.
7983 (syms_of_charset): Use it instead of xmalloc. This removes a
7984 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7985 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7986 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7987 Move back to alloc.c.
7988 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7989 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7990
7991 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7992
7993 * nsterm.m (windowDidResize): Call x_set_window_size only when
7994 ns_in_resize is true. Otherwise set pixelwidth/height and
7995 call change_frame_size (Bug#9628).
7996
7997 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7998
7999 Port --enable-checking=all to Fedora 14 x86-64.
8000 * charset.c (syms_of_charset): Also account for glibc malloc's
8001 internal overhead when calculating the initial malloc maximum.
8002
8003 Port --enable-checking=all to Fedora 14 x86.
8004 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8005 Move to lisp.h.
8006 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
8007 (overrun_check_realloc, overrun_check_free):
8008 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
8009 That way, xmalloc returns a properly-aligned pointer even if
8010 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
8011 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
8012 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
8013 into account when calculating the initial malloc maximum.
8014 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8015 Move here from alloc.c, so that charset.c can use it too.
8016 Properly align; the old code wasn't right for common 32-bit hosts
8017 when configured with --enable-checking=all.
8018 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8019 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
8020
8021 2011-09-29 Eli Zaretskii <eliz@gnu.org>
8022
8023 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
8024 use EDOM.
8025
8026 2011-09-28 Eli Zaretskii <eliz@gnu.org>
8027
8028 * xdisp.c (compute_display_string_end): If there's no display
8029 string at CHARPOS, return -1.
8030
8031 * bidi.c (bidi_fetch_char): When compute_display_string_end
8032 returns a negative value, treat the character as a normal
8033 character not covered by a display string. (Bug#9624)
8034
8035 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
8036
8037 * lread.c (Fread_from_string): Fix typo in docstring.
8038
8039 2011-09-27 Eli Zaretskii <eliz@gnu.org>
8040
8041 * xdisp.c (handle_invisible_prop): If invisible text ends on a
8042 newline, reseat the iterator instead of bidi-iterating there one
8043 character at a time. (Bug#9610)
8044 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
8045 TO_CHARPOS if the bidi iterator is at base embedding level.
8046
8047 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
8048
8049 * lread.c (readevalloop): Use correct code for NBSP.
8050 (read1): Likewise. (Bug#9608)
8051
8052 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
8053
8054 * dbusbind.c (Fdbus_register_signal): When service is not

8056
8057 2011-09-25 Glenn Morris <rgm@gnu.org>

8065
8066 2011-09-24 Glenn Morris <rgm@gnu.org>
8067
8068 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)

8075
8076 2011-09-24 Eli Zaretskii <eliz@gnu.org>
8077
8078 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
8079 Default value is now t. Doc fix.
8080
8081 * indent.c (Fvertical_motion): Compute and apply the overshoot
8082 logic when moving up, not only when moving down. Fix the
8083 confusing name and values of the it_overshoot_expected variable;
8084 logic changes accordingly. (Bug#9254) (Bug#9549)
8085
8086 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
8087 CHARPOS is covered by a display string which includes newlines.
8088 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
8089 is covered by a display string with embedded newlines.
8090
8091 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
8092
8093 * dbusbind.c (Fdbus_register_signal): Add match rule to
8094 Vdbus_registered_objects_table. (Bug#9581)
8095 (Fdbus_register_method, Vdbus_registered_objects_table):
8096 Fix docstring.
8097
8098 2011-09-24 Jim Meyering <meyering@redhat.com>
8099
8100 do not ignore write error for any output size
8101 The previous change was incomplete.
8102 While it makes emacs --batch detect the vast majority of stdout
8103 write failures, errors were still ignored whenever the output size is
8104 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
8105 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
8106 && echo FAIL: ignored write error
8107 FAIL: ignored write error
8108 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
8109 && echo FAIL: ignored write error
8110 FAIL: ignored write error
8111 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
8112
8113 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
8114
8115 * emacs.c (Fkill_emacs): In noninteractive mode exit
8116 non-successfully if a write error occurred on stdout. (Bug#9574)
8117
8118 2011-09-21 Eli Zaretskii <eliz@gnu.org>
8119
8120 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
8121 the xassert test.
8122
8123 * dispextern.h (struct it): Update the comment documenting what
8124 can it->OBJECT be.
8125
8126 2011-09-20 Eli Zaretskii <eliz@gnu.org>
8127
8128 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
8129 a display string, extend search for cursor position to end of row.
8130 (find_row_edges): If the row ends in a newline from a display
8131 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
8132 Handle the case of a display string with multiple newlines.
8133 (Fcurrent_bidi_paragraph_direction): Fix search for previous
8134 non-empty line. Fixes confusing cursor motion with arrow keys at
8135 the beginning of a line that starts with whitespace.
8136
8137 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8138
8139 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
8140 (bug#9493).

8148
8149 * xdisp.c (display_line): Record maximum and minimum buffer
8150 positions even if no glyphs were produced (e.g., by a zero-width
8151 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
8152 buffer positions that will be removed from the glyph row because
8153 they don't fit.
8154 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
8155 column is beyond frame width: don't subtract 1 "pixel" when
8156 computing width of the stretch.
8157 (reseat_at_next_visible_line_start): Undo the change made on
8158 2011-09-17 that saved paragraph information and restored it after
8159 the call to `reseat'. (Bug#9545)
8160
8161 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8162
8163 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
8164 and turn window cursor on if cleared (Bug#9415).
8165
8166 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
8167
8168 * search.c (boyer_moore): Take unibyte characters from pattern
8169 literally. (Bug#9458)
8170
8171 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8172

8175 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
8176
8177 Fix minor problem found by static checking.
8178 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
8179 initialized, to pacify gcc -Wuninitialized.
8180
8181 * fileio.c: Report proper errno when syscall falls.
8182 (Finsert_file_contents): Save and restore errno,
8183 so that report_file_error outputs the correct diagnostic.
8184 (Fwrite_region) [CLASH_DETECTION]: Likewise.
8185
8186 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8187

8189
8190 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8191
8192 * xdisp.c (produce_stretch_glyph): Another fix for changes made on

8194
8195 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8196
8197 * xdisp.c (reseat_at_next_visible_line_start): Keep information
8198 about the current paragraph and restore it after the call to reseat.
8199
8200 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
8201 (bidi_find_paragraph_start): Search back for paragraph beginning
8202 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
8203 (bidi_move_to_visually_next): Only trigger paragraph-related
8204 computations when the last character is a newline or at EOB, not
8205 just any NEUTRAL_B. (Bug#9470)
8206
8207 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
8208 truncated lines if point is covered by a display string. (Bug#9524)
8209
8210 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
8211
8212 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8213 (cons_to_x_long): New function.
8214 (lisp_data_to_selection_data): Use it. Correct the test for
8215 short-versus-long data; it was negated. Break out of vector
8216 loop, for efficiency, when a long datum is discovered.
8217
8218 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8219
8220 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8221
8222 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8223
8224 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
8225 GCC PR/17406) by declaring this function with external scope.
8226
8227 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8228
8229 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
8230 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
8231
8232 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
8233

8247
8248 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8249 This occurs when processing a multibyte format.
8250 Problem reported by Wolfgang Jenker.
8251
8252 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8253

8255 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8256
8257 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8258
8259 Remove unused external symbols.
8260 * dispextern.h (calc_pixel_width_or_height): Remove decl.

8266
8267 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8268
8269 * xselect.c: Use signed conversions more consistently (Bug#9498).
8270 (selection_data_to_lisp_data): Assume incoming selection data are
8271 signed integers, not unsigned. This is to be consistent with
8272 outgoing selection data, which was modified to use signed integers
8273 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8274 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8275 expects long, not unsigned long.
8276
8277 2011-09-14 Eli Zaretskii <eliz@gnu.org>
8278
8279 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect

8286
8287 2011-09-12 Eli Zaretskii <eliz@gnu.org>
8288
8289 * indent.c (compute_motion): Process display vector front to back
8290 rather than the other way around. (Bug#2496)
8291
8292 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>

8295
8296 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
8297
8298 * minibuf.c (Fread_from_minibuffer): Doc fix.
8299
8300 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8301
8302 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8303 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8304
8305 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8306
8307 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8308 value for non-existent files.
8309
8310 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8311
8312 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8313 set its "size" to -1. This will set the modtime_size field of
8314 the corresponding buffer to -1, which is what
8315 verify-visited-file-modtime expects for files that do not exist.
8316 (Bug#9139)
8317
8318 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8319
8320 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8321 here ...
8322 * lisp.h: ... from here. push_key_description is no longer
8323 defined in keyboard.c, so its declaration should not be in
8324 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8325 logically belongs with push_key_description.
8326
8327 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8328
8329 * buffer.h: Include <sys/types.h> instead of <time.h>.
8330 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8331 Problem reported by Herbert J. Skuhra.
8332
8333 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>

8346 redisplay in small windows.
8347
8348 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8349
8350 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8351
8352 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8353
8354 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8355 Operate on live windows only.
8356
8357 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8358
8359 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.

8361 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8362

8370 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8371
8372 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8373 Without this fix, the command to link temacs failed due to an
8374 undefined symbol __builtin_isnan. This is because
8375 /usr/include/iso/math_c99.h #defines isnan(x) to
8376 __builtin_isnan(x), but the bundled gcc, which identifies itself
8377 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8378 a __builtin_isnan.
8379 * floatfns.c (isnan): #undef, and then #define to a clone of
8380 what's in data.c.
8381 (Fisnan): Always define, since it's always available now.
8382 (syms_of_floatfns): Always define isnan at the Lisp level.
8383
8384 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8385
8386 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8387
8388 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8389
8390 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8391 The previous code assumed that file offsets (off_t values) fit in
8392 EMACS_INT variables, which is not true on typical 32-bit hosts.
8393 The code messed up by falsely reporting buffer overflow in cases
8394 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8395 when "big" contains more than 2**29 bytes, even though this
8396 inserts just one byte and does not overflow the buffer.
8397 (Finsert_file_contents): Store file offsets as off_t
8398 values, not as EMACS_INT values. Check for overflow when
8399 converting between EMACS_INT and off_t. When checking for
8400 buffer overflow or for overlap, take the offsets into account.
8401 Don't use EMACS_INT for small values where int suffices.
8402 When checking for overlap, fix a typo: ZV was used where
8403 ZV_BYTE was intended.
8404 (Fwrite_region): Don't assume off_t fits into 'long'.
8405 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8406
8407 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8408
8409 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8410
8411 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8412
8413 sprintf-related integer and memory overflow issues (Bug#9412).
8414
8415 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8416 (esprintf, exprintf, evxprintf): New functions.
8417 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8418 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8419 (modify_event_symbol): Do not assume that the length of
8420 name_alist_or_stem is safe to alloca and fits in int.
8421 (Fexecute_extended_command): Likewise for function name and binding.
8422 (Frecursion_depth): Wrap around reliably on integer overflow.
8423 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8424 since some callers pass EMACS_INT values.
8425 (Fsingle_key_description): Don't crash if symbol name contains more
8426 than MAX_ALLOCA bytes.
8427 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8428 (get_minibuffer): Arg is now EMACS_INT, not int.
8429 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8430 (esprintf, exprintf, evxprintf): New decls.
8431 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8432
8433 * dbusbind.c (signature_cat): New function.
8434 (xd_signature, Fdbus_register_signal):
8435 Do not overrun buffer; instead, report string overflow.
8436
8437 * dispnew.c (add_window_display_history): Don't overrun buffer.
8438 Truncate instead; this is OK since it's just a log.
8439
8440 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8441 even if the time zone offset is outlandishly large.
8442 Don't mishandle offset == INT_MIN.
8443
8444 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8445 when creating daemon; the previous buffer-overflow check was incorrect.
8446
8447 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8448 which has the guts of the old verror function.
8449
8450 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8451 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8452
8453 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8454 (font_unparse_xlfd): Don't blindly alloca long strings.
8455 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8456 fits in int, when using sprintf. Use single snprintf to count
8457 length of string rather than counting it via multiple sprintfs;
8458 that's simpler and more reliable.
8459 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8460 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8461 sprintf, in case result does not fit in int.
8462
8463 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8464 (fontset_from_font): Print it.
8465
8466 * frame.c (tty_frame_count): Now printmax_t, not int.
8467 (make_terminal_frame, set_term_frame_name): Print it.
8468 (x_report_frame_params): In X, window IDs are unsigned long,
8469 not signed long, so print them as unsigned.
8470 (validate_x_resource_name): Check for implausibly long names,
8471 and don't assume name length fits in 'int'.
8472 (x_get_resource_string): Don't blindly alloca invocation name;
8473 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8474 not fit in int.
8475
8476 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8477 (xg_check_special_colors, xg_set_geometry):
8478 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8479
8480 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8481 Use esprintf, not sprintf, in case result does not fit in int.
8482
8483 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8484 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8485 it as a large positive number.
8486 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8487 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8488
8489 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8490 in case result does not fit in int.
8491
8492 * print.c (float_to_string): Detect width overflow more reliably.
8493 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8494 buffer overrun. Don't assume list length fits in 'int'. Treat
8495 print length of 0 as 0, not as infinity; to be consistent with other
8496 uses of print length in this function. Don't overflow print length
8497 index. Don't assume hash table size fits in 'long', or that
8498 vectorlike size fits in 'unsigned long'.
8499
8500 * process.c (make_process): Use printmax_t, not int, to format
8501 process-name gensyms.
8502
8503 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8504
8505 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8506 to avoid potential buffer overrun.
8507
8508 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8509 if X resource line is longer than 512 bytes.
8510
8511 * xfns.c (x_window): Make sprintf buffer a bit bigger
8512 to avoid potential buffer overrun.
8513
8514 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8515
8516 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8517
8518 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8519
8520 Integer overflow fixes for scrolling, etc.
8521 Without these, Emacs silently mishandles large integers sometimes.
8522 For example, "C-u 4294967297 M-x recenter" was treated as if
8523 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8524
8525 * xdisp.c (try_window_id): Check Emacs fixnum range before
8526 converting to 'int'.
8527
8528 * window.c (window_scroll_line_based, Frecenter):
8529 Check that an Emacs fixnum is in range before assigning it to 'int'.
8530 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8531 values converted from Emacs fixnums.
8532 (Frecenter): Don't wrap around a line count if it is out of 'int'
8533 range; instead, treat it as an extreme value.
8534 (Fset_window_configuration, compare_window_configurations):
8535 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8536
8537 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8538 that can exceed INT_MAX. Check that EMACS_INT value is in range
8539 before assigning it to the (possibly-narrower) index.
8540 (match_limit): Don't assume that a fixnum can fit in 'int'.
8541
8542 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8543 exceed INT_MAX.
8544
8545 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8546 (Fvertical_motion): Don't wrap around LINES values that don't fit
8547 in 'int'. Instead, treat them as extreme values. This is good
8548 enough for windows, which can't have more than INT_MAX lines anyway.
8549
8550 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8551
8552 * Require libxml/parser.h to avoid compilation warning.
8553
8554 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8555
8556 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8557 since this reportedly can destroy thread storage.
8558
8559 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8560
8561 * syntax.c (find_defun_start): Update all cache variables if
8562 exiting early (Bug#9401).
8563
8564 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8565
8566 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8567
8568 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8569 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8570 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8571
8572 * term.c (tty_append_glyph): New function.
8573 (produce_stretch_glyph): Static function and its prototype deleted.
8574
8575 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8576 Add prototypes.
8577
8578 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8579
8580 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8581 when checking :margin (Bug#9390).
8582 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8583 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8584 so that the name doesn't mislead. All uses changed.
8585
8586 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8587
8588 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8589 set_tty_hooks.
8590
8591 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8592
8593 * xdisp.c (move_it_to): Don't bail out early when reaching
8594 position beyond to_charpos, if we are scanning backwards.
8595 (move_it_vertically_backward): When DY == 0, make sure we get to
8596 the first character in the line after the newline.
8597
8598 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8599
8600 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8601 (ccl_driver): Do not generate an out-of-range pointer.
8602 (Fccl_execute_on_string): Remove unnecessary check for
8603 integer overflow, noted by Stefan Monnier in
8604 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8605 Remove a FIXME that didn't need fixing.
8606 Simplify the newly-introduced buffer reallocation code.
8607
8608 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8609
8610 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8611
8612 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8613
8614 Integer and memory overflow issues (Bug#9196).
8615
8616 * doc.c (get_doc_string): Rework so that
8617 get_doc_string_buffer_size is the actual buffer size, rather than
8618 being 1 less than the actual buffer size; this makes xpalloc more
8619 convenient.
8620
8621 * image.c (x_allocate_bitmap_record, cache_image):
8622 * xselect.c (Fx_register_dnd_atom):
8623 Simplify previous changes by using xpalloc.
8624
8625 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8626 since either will do and ptrdiff_t is convenient with xpalloc.
8627
8628 * charset.c (charset_table_size)
8629 (struct charset_sort_data.priority): Now ptrdiff_t.
8630 (charset_compare): Don't overflow if priorities differ greatly.
8631 (Fsort_charsets): Don't assume list length fits in int.
8632 Check for size-calculation overflow when allocating sort data.
8633 (syms_of_charset): Allocate an initial charset table that is
8634 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8635
8636 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8637
8638 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8639 The actual value is always <= INT_MAX, and leaving it unsigned made
8640 overflow checking harder.
8641
8642 * dispextern.h (struct glyph_matrix.rows_allocated)
8643 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8644 with xpalloc. The values are still always <= INT_MAX.
8645
8646 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8647
8648 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8649 (SAFE_NALLOCA): New macro.
8650
8651 * region-cache.c (struct boundary.pos, find_cache_boundary)

8653 (set_cache_region, invalidate_region_cache)
8654 (revalidate_region_cache, know_region_cache, region_cache_forward)
8655 (region_cache_backward, pp_cache):
8656 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8657 so that ptrdiff_t * can be passed to xpalloc.
8658 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8659 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8660 (pp_cache): Don't assume cache_len fits in int.
8661 * region-cache.h: Adjust extern decls to match.
8662
8663 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8664 EMACS_INT, since either will do, for xpalloc.
8665
8666 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8667 (xnmalloc, xnrealloc, xpalloc): New functions.
8668
8669 * bidi.c (bidi_shelve_header_size): New constant.
8670 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8671 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8672
8673 * bidi.c (bidi_cache_shrink):
8674 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8675 (overlay_strings):
8676 Don't update size of array until after memory allocation succeeds,
8677 because xmalloc/xrealloc may not return.
8678 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8679 now that we have proper integer overflow checking.
8680 (record_overlay_string, overlay_strings): Catch overflows when
8681 calculating size of overlay_str_buf.
8682
8683 * callproc.c (Fcall_process): Check for size overflow when
8684 calculating size of args2.
8685 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8686 Normally we prefer signed values, but sticking with ptrdiff_t would
8687 require adding more-complicated checks.
8688
8689 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8690 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8691 Redo buffer-overflow calculations to avoid integer overflow.
8692 Add a FIXME comment where memory seems to be over-allocated.
8693
8694 * character.c (Fstring): Check for size-calculation overflow.
8695
8696 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8697 unnecessary integer overflow. Check for size overflow.
8698 (encode_coding_object): Don't update size until xmalloc succeeds.
8699
8700 * composite.c (get_composition_id): Check for overflow in glyph
8701 length calculations.
8702

8705 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8706 (scrolling_window): Check for overflow in size calculations.
8707 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8708 Don't assume glyph table len fits in int.

8710 (row_table_size): Now ptrdiff_t, not int.
8711 (scrolling_window): Avoid overflow in size calculations.
8712 Don't update size until allocation succeeds.
8713 * fns.c (concat): Check for overflow in size calculations.
8714 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.

8722 EMACS_INT, where ptrdiff_t will do.
8723 (Fsubstitute_command_keys): Check for string overflow.
8724
8725 * editfns.c (set_time_zone_rule): Don't assume environment length
8726 fits in int.
8727 (message_length): Now ptrdiff_t, not int.
8728 (Fmessage_box): Don't update size until allocation succeeds.
8729 Don't assume message length fits in int.
8730 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8731
8732 * emacs.c (main): Do not reallocate argv, since there is a null at
8733 the end that can be overwritten, and this way there's no need to
8734 worry about size-calculation overflow.
8735 (sort_args): Check for size-calculation overflow.
8736
8737 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8738 alloc succeeds.
8739 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8740
8741 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8742 (x_set_scroll_bar_width, x_figure_window_size):
8743 Check for integer overflow.
8744 (x_set_alpha): Do not assume XINT fits in int.
8745
8746 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8747 This is for the members text_lines, text_cols, total_lines, total_cols,
8748 where the system imposes an 'int' limit.
8749
8750 * fringe.c (Fdefine_fringe_bitmap):
8751 Don't update size until alloc works.
8752
8753 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8754 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8755
8756 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8757 Check for size-calculation overflow.
8758 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8759 do, as we prefer signed integers.
8760 (id_to_widget.max_size, id_to_widget.used)
8761 (xg_store_widget_in_map, xg_remove_widget_from_map)
8762 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8763 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8764 Use and return ptrdiff_t, not int.
8765 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8766 * gtkutil.h: Change prototypes to match the above.
8767
8768 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8769 are duplicate now that they've been promoted to lisp.h.
8770 (x_allocate_bitmap_record, x_alloc_image_color)
8771 (make_image_cache, cache_image, xpm_load):
8772 Don't update size until alloc is done.
8773 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8774 (x_detect_edges):
8775 Check for size calculation overflow.

8782 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8783 Use ptrdiff_t, not int, to count maps.
8784 (read_char_minibuf_menu_prompt): Check for overflow in size
8785 calculations. Don't update size until allocation succeeds.
8786 Redo calculations to avoid overflow.
8787 * keyboard.h: Change prototypes to match the above.
8788
8789 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
8790 to count maps.
8791 (current_minor_maps): Check for size calculation overflow.
8792 * keymap.h: Change prototypes to match the above.

8814
8815 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8816 for command line length. Do not attempt to address one before the
8817 beginning of an array, as that's not portable.
8818
8819 * term.c (max_frame_lines): Remove; unused.
8820 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8821 not int.
8822 (encode_terminal_code, calculate_costs): Check for size
8823 calculation overflow.

8828
8829 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
8830 subtracting pointers.
8831 (gobble_line): Check for overflow more carefully. Don't update size
8832 until alloc done.
8833
8834 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
8835 Don't update size until alloc done.

8846 (Finternal_make_lisp_face, cache_face):
8847 Check for size calculation overflow.
8848 (cache_face): Treat size calculation overflows as if they were

8850
8851 * xfns.c (x_encode_text, x_set_name_internal)
8852 (Fx_change_window_property): Use ptrdiff_t, not int, to count

8857 (xg_select): Check for size calculation overflow.
8858 Don't update size until alloc done.
8859
8860 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8861 as sprintf is limited to int lengths.
8862
8863 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8864 (X_LONG_MIN): New macros.
8865 Use them to make the following changes clearer.
8866 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8867 This change doesn't affect the value now, but it may help remind
8868 future maintainers not to raise the value too much later.
8869 (SELECTION_QUANTUM): Remove, replacing with ...
8870 (selection_quantum): ... new function, which avoids overflow.
8871 All uses changed.
8872 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8873 assumption that selection length fits in 'int'.

8875 (x_get_window_property, receive_incremental_selection)
8876 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8877 (lisp_data_to_selection_data, clean_local_selection_data):

8879 (x_reply_selection_request, x_get_window_property)
8880 (receive_incremental_selection, x_property_data_to_lisp):
8881 Redo calculations to avoid overflow.
8882 (x_reply_selection_request): When sending hint, ceiling it at
8883 X_LONG_MAX rather than relying on wraparound overflow to send
8884 something.
8885 (x_get_window_property, receive_incremental_selection)
8886 (lisp_data_to_selection_data, x_property_data_to_lisp):

8890 Don't store size until memory allocation succeeds.
8891 (x_get_window_property): Plug memory leak on memory exhaustion.
8892 Don't double-block input; malloc is safe here. Don't assume 2**34
8893 - 4 fits in unsigned long. Add an xassert to check
8894 XGetWindowProperty overflow. Be more careful about overflow
8895 calculations, and distinguish size from memory overflow better.
8896 (receive_incremental_selection): When tracing, don't assume
8897 unsigned int is less than INT_MAX.
8898 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8899 harmful) conversions of unsigned short to int.
8900 (lisp_data_to_selection_data): Don't assume that integers
8901 in the range -65535 through -1 fit in an X unsigned short.
8902 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8903 result parameters unless successful. Rely on cons_to_unsigned
8904 to report problems with elements; the old code wasn't right anyway.
8905 (x_check_property_data): Check for int overflow; we cannot use
8906 a wider type due to X limits.
8907 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8908
8909 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

8916 (x_term_init): Don't assume length fits in int (sprintf is limited
8917 to int size).
8918

8938 * image.c (xpm_get_color_table_h):
8939 * lisp.h (hash_lookup, hash_put):
8940 * minibuf.c (Ftest_completion):
8941 Use ptrdiff_t for hash table indexes, not int (which is too
8942 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8943 32-bit --with-wide-int hosts).
8944
8945 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8946 Add a FIXME comment about memory leaks.
8947 (syms_of_charset): Don't assume xmalloc returns.
8948

8954 with outlandish widths.
8955 * character.h (sanitize_tab_width): Rename from sanitize_width,
8956 now that we have two such functions. All uses changed.
8957 (sanitize_char_width): New inline function.
8958
8959 Don't assume that tab-width fits in int.
8960 * character.h (sanitize_width): New inline function.
8961 (SANE_TAB_WIDTH): New macro.
8962 (ASCII_CHAR_WIDTH): Use it.

8966
8967 * fileio.c: Integer overflow issues with file modes.
8968 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
8969
8970 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
8971 Remove unreachable code.
8972 (read_hex, load_charset_map_from_file): Check for integer overflow.
8973
8974 * xterm.c: Don't go over XClientMessageEvent limit.
8975 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8976 (x_send_scroll_bar_event): Likewise. Check that the size does not
8977 exceed limits imposed by XClientMessageEvent, as well as the usual
8978 ptrdiff_t and size_t limits.
8979
8980 * keyboard.c: Overflow, signedness and related fixes.
8981 (make_lispy_movement): Use same integer type in forward decl
8982 that is used in the definition.
8983 (read_key_sequence, keyremap_step):
8984 Change bufsize argument back to int, undoing my 2011-03-30 change.
8985 We prefer signed types, and int is wide enough here.
8986 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8987 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8988 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8989 length, not size_t. Use ptrdiff_t for index, not int.
8990 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8991 possibility of integer overflow.
8992
8993 Overflow, signedness and related fixes for images.

9001 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
9002 * nsmenu.m (update_frame_tool_bar):
9003 * xdisp.c (calc_pixel_width_or_height):
9004 * xfns.c (image_cache_refcount):
9005 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
9006 on typical 64-bit hosts.
9007
9008 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
9009 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

9012 when the callers expect that.
9013 (image_ascent): Redo ascent calculation to avoid int overflow.
9014 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
9015 (lookup_image): Remove unnecessary tests.
9016 (xbm_image_p): Locals are now of int, not EMACS_INT,
9017 since parse_image_check makes sure they fit into int.
9018 (png_load, gif_load, svg_load_image):
9019 Prefer int to unsigned where either will do.
9020 (tiff_handler): New function, combining the cores of the
9021 old tiff_error_handler and tiff_warning_handler.
9022 This function is rewritten to use vsnprintf and thereby avoid
9023 stack buffer overflows. It uses only the features of vsnprintf
9024 that are common to both POSIX and native Microsoft.
9025 (tiff_error_handler, tiff_warning_handler): Use it.
9026 (tiff_load, gif_load, imagemagick_load_image):
9027 Don't assume :index value fits in 'int'.
9028 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
9029 (imagemagick_load_image): Check that crop parameters fit into
9030 the integer types that MagickCropImage accepts. Don't assume
9031 Vimagemagick_render_type has a nonnegative value. Don't assume
9032 size_t fits in 'long'.
9033 (gs_load): Use printmax_t to print the widest integers possible.
9034 Check for integer overflow when computing image height and width.

9040
9041 2011-08-25 Eli Zaretskii <eliz@gnu.org>
9042
9043 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
9044 the display spec is of the form `(space ...)'.
9045 (handle_display_spec): Return the value returned by
9046 handle_single_display_spec, not just 1 or zero.
9047 (handle_single_display_spec): If the display spec is of the form
9048 `(space ...)', and specifies display in the text area, return 2
9049 rather than 1.
9050 (try_cursor_movement): Check for the need to scroll more
9051 accurately, and prefer exact match for point under bidi.
9052 Don't advance `row' beyond the last row of the window.
9053
9054 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
9055 into disp_prop; all users changed.
9056
9057 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
9058 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
9059 for the text covered by the display property.

9068
9069 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
9070 buffers, return left-to-right.
9071 (set_cursor_from_row): Consider candidate row a win if its glyph
9072 represents a newline and point is on that newline. Fixes cursor
9073 positioning on the newline at EOL of R2L text within L2R
9074 paragraph, and vice versa.
9075 (try_cursor_movement): Check continued rows, in addition to
9076 continuation rows. Fixes unwarranted scroll when point enters a
9077 continued line of R2L text within an L2R paragraph, or vice versa.
9078 (cursor_row_p): Consider the case of point being equal to
9079 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
9080 from the end of a short line to the beginning of a continued line
9081 of R2L text within L2R paragraph.
9082 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
9083 composed characters.
9084
9085 * bidi.c (bidi_check_type): Use xassert.
9086 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
9087 members.
9088
9089 2011-08-23 Eli Zaretskii <eliz@gnu.org>

9104
9105 * xdisp.c (redisplay_window): When computing centering_position,
9106 account for the height of the header line. (Bug#8874)
9107
9108 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
9109 instead of CHAR_TO_BYTE. Fixes a crash when a completion
9110 candidate is selected by the mouse, and that candidate has a
9111 composed character under the mouse.
9112
9113 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
9114 coordinates reported by pos-visible-in-window-p for a composed
9115 character in column zero.
9116
9117 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

9121 2011-08-22 Eli Zaretskii <eliz@gnu.org>
9122
9123 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
9124 consider it a hit if to_charpos is anywhere in the range of the
9125 composed buffer positions.
9126
9127 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
9128
9129 * image.c (gif_load): Don't assume that each subimage has the same
9130 dimensions as the base image. Handle disposal method that is
9131 "undefined" by the gif spec (Bug#9335).
9132
9133 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
9134

9139
9140 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
9141 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
9142 from an Org mode buffer to a Speedbar frame.
9143
9144 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
9145 a composition, take its buffer position from IT->cmp_it.charpos.
9146 Fixes cursor positioning at the beginning of a line that begins
9147 with a composed character.
9148
9149 2011-08-18 Eli Zaretskii <eliz@gnu.org>
9150
9151 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
9152 character bidirectional type, use STRONG_L instead. Fixes crashes
9153 in a buffer produced by `describe-categories'.
9154
9155 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
9156 members before the level stack, so they would be saved and
9157 restored when copying iterator state. Fixes incorrect reordering
9158 around TABs covered by display properties.
9159
9160 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
9161

9246 the event loop. Get status from as_status (Bug#7276).
9247
9248 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9249 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
9250 the event loop (Bug#7276).

9285
9286 * xdisp.c (iterate_out_of_display_property): xassert that
9287 IT->position is set to within IT->object's boundaries. Break from
9288 the loop as soon as EOB is reached; avoids infloops in redisplay
9289 when IT->position is set up wrongly due to some bug.
9290 Set IT->current to match the bidi iterator unconditionally.
9291 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9292 entry. Force push_it to save on the stack the current
9293 buffer/string position, to be restored by pop_it. Fix flags in
9294 the iterator structure wrt the object coming from a display
9295 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9296 properties. (Bug#9284)
9297
9298 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9299

9336
9337 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9338 display property strides EOL and includes a newline, as in
9339 longlines-mode. (Bug#9254)
9340 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9341 word-wrap under bidirectional display. (Bug#9224)
9342
9343 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9344 is non-zero, even if the data buffer is NULL. Fixes a crash in
9345 vertical-motion with longlines-mode. (Bug#9254)
9346
9347 2011-08-05 Eli Zaretskii <eliz@gnu.org>

9355 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9356 amount allocated this far in `bidi_cache_total_alloc'.
9357 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9358 non-zero, only free the data buffer without restoring the cache
9359 contents. All callers changed.
9360
9361 * dispextern.h (bidi_unshelve_cache): Update prototype.
9362
9363 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9364 (move_it_in_display_line, move_it_to)
9365 (move_it_vertically_backward, move_it_by_lines): Replace the call
9366 to xfree to an equivalent call to bidi_unshelve_cache.

9386
9387 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9388
9389 * xterm.c (x_find_topmost_parent): New function.
9390 (x_set_frame_alpha): Find topmost parent window with
9391 x_find_topmost_parent and set the property there also (bug#9181).
9392 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9393
9394 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9395
9396 * callproc.c (Fcall_process): Avoid vfork clobbering
9397 the local vars buffer, coding_systems, current_dir.
9398
9399 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9400
9401 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9402
9403 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9404
9405 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9406 so that it is not optimized away.
9407
9408 * xdisp.c (compute_display_string_pos): Remove unused local.
9409
9410 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9411
9412 Fix slow cursor motion and scrolling in large buffers with
9413 selective display, like Org Mode buffers. (Bug#9218)
9414
9415 * dispextern.h (struct bidi_it): New member disp_prop_p.
9416
9417 * xdisp.c: Remove one-slot cache of display string positions.
9418 (compute_display_string_pos): Accept an additional argument
9419 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9420 for a display string or property. If found, set DISP_PROP_P
9421 non-zero.
9422
9423 * bidi.c (bidi_fetch_char): Accept an additional argument
9424 DISP_PROP_P, and pass it to compute_display_string_pos.
9425 Only handle text covered by a display string if DISP_PROP_P is returned
9426 non-zero. All callers of bidi_fetch_char changed.
9427
9428 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9429
9430 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9431
9432 2010-12-03 Don March <don@ohspite.net>
9433
9434 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9435 last character M-[char] is translated to ESC [char] (bug#7541).
9436
9437 2011-08-02 Kenichi Handa <handa@m17n.org>
9438
9439 * lisp.h (uniprop_table): Extern it.
9440
9441 * chartab.c (uniprop_table): Make it non-static.
9442
9443 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9444
9445 * xdisp.c (forward_to_next_line_start): Accept additional argument
9446 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9447 on the newline.
9448 (reseat_at_next_visible_line_start): Use the bidi iterator state
9449 returned by forward_to_next_line_start to restore the state of
9450 it->bidi_it after backing up to previous newline. (Bug#9212)
9451
9452 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9453
9454 * regex.c (re_comp): Protoize.
9455 (re_exec): Fix return type.
9456 (regexec): Fix type of `ret'. (Bug#9203)
9457
9458 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9459
9460 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9461 This is needed if max-image-size is a floating-point number.
9462
9463 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9464
9465 * print.c (print_object): Print empty symbol as ##.
9466
9467 * lread.c (read1): Read ## as empty symbol.
9468
9469 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9470
9471 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9472 setting frame foreground color (Bug#9175).
9473 (x_set_background_color): Likewise.
9474
9475 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9476 contents (Bug#9176).
9477 (EmacsTooltip -init): Remove bezels and add shadows to
9478 tooltip windows.
9479
9480 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9481 or scroll bar (Bug#8470).
9482
9483 * nsfont.m (nsfont_open): Remove assignment to voffset and
9484 unnecessary vars hshink, expand, hd, full_height, min_height.
9485 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9486
9487 * nsterm.h (nsfont_info): Remove voffset field.
9488
9489 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9490
9491 Implement strike-through and overline on NextStep (Bug#8863).
9492
9493 * nsfont.m (nsfont_open): Use underline position provided by font,
9494 instead of hard-coded value of 2.
9495 (nsfont_draw): Call ns_draw_text_decoration instead.
9496
9497 * nsterm.h: Add declaration for ns_draw_text_decoration.
9498
9499 * nsterm.m (ns_draw_text_decoration): New function for drawing
9500 underline, overline, and strike-through.
9501 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9502 ns_draw_text_decoration. Change treatment of cursor drawing to
9503 accommodate underlining, etc.
9504
9505 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9506
9507 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9508 default.
9509
9510 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9511
9512 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9513 Without this fix, if a signal arrives just after memory fills up,
9514 'malloc' might be invoked reentrantly.
9515
9516 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9517 In other words, assume that every image size is allowed, on non-X
9518 hosts. This assumption is probably wrong, but it lets Emacs compile.
9519
9520 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9521
9522 * regex.c (re_iswctype): Convert return values to boolean.
9523
9524 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9525
9526 * xdisp.c (compute_display_string_pos): Don't use cached display
9527 string position if the buffer had its restriction changed.
9528 (Bug#9184)
9529
9530 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9531
9532 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9533
9534 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9535
9536 Integer signedness and overflow and related fixes. (Bug#9079)
9537
9538 * bidi.c: Integer size and overflow fixes.
9539 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9540 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9541 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9542 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9543 (bidi_find_other_level_edge):
9544 Use ptrdiff_t instead of EMACS_INT where either will do.
9545 This works better on 32-bit hosts configured --with-wide-int.
9546 (bidi_cache_ensure_space): Check for size-calculation overflow.
9547 Use % rather than repeated addition, for better worst-case speed.
9548 Don't set bidi_cache_size until after xrealloc returns, because it
9549 might not return.
9550 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9551 (bidi_cache_ensure_space): Also check that the bidi cache size
9552 does not exceed that of the largest Lisp string or buffer. See Eli
9553 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9554
9555 * alloc.c (__malloc_size_t): Remove.
9556 All uses replaced by size_t. See Andreas Schwab's note
9557 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9558
9559 * image.c: Improve checking for integer overflow.
9560 (check_image_size): Assume that f is nonnull, since
9561 it is always nonnull in practice. This is one less thing to
9562 worry about when checking for integer overflow later.
9563 (x_check_image_size): New function, which checks for integer
9564 overflow issues inside X.
9565 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9566 This removes the need for a memory_full check.
9567 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9568 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9569 (xbm_read_bitmap_data): Change locals back to 'int', since
9570 their values must fit in 'int'.
9571 (xpm_load_image, png_load, tiff_load):
9572 Invoke x_create_x_image_and_pixmap earlier,
9573 to avoid much needless work if the image is too large.
9574 (tiff_load): Treat overly large images as if
9575 x_create_x_image_and_pixmap failed, not as malloc failures.
9576 (gs_load): Use x_check_image_size.
9577
9578 * gtkutil.c: Omit integer casts.
9579 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9580 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9581
9582 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9583
9584 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9585 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9586 would wrongly return t on a 64-bit host.
9587
9588 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9589 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9590 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9591 and therefore cause GCC to emit a bogus diagnostic in some cases.
9592
9593 * image.c: Integer signedness and overflow and related fixes.
9594 This is not an exhaustive set of fixes, but it's time to
9595 record what I've got.
9596 (lookup_pixel_color, check_image_size): Remove redundant decls.
9597 (check_image_size): Don't assume that arbitrary EMACS_INT values
9598 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9599 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9600 (tiff_load, imagemagick_load_image):
9601 Check for overflow in size calculations.
9602 (x_create_x_image_and_pixmap): Remove unnecessary test for
9603 xmalloc returning NULL; that can't happen.
9604 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9605 (xpm_color_bucket): Use better integer hashing function.
9606 (xpm_cache_color): Don't possibly over-allocate memory.
9607 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9608 (gif_memory_source):
9609 Use ptrdiff_t, not int or size_t, to record sizes.
9610 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9611 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9612 either works, as we prefer signed integers.
9613 (tiff_read_from_memory, tiff_write_from_memory):
9614 Return tsize_t, not size_t, since that's what the TIFF API wants.
9615 (tiff_read_from_memory): Don't fail simply because the read would
9616 go past EOF; instead, return a short read.
9617 (tiff_load): Omit no-longer-needed casts.
9618 (Fimagemagick_types): Don't assume size fits into 'int'.
9619
9620 Improve hashing quality when configured --with-wide-int.
9621 * fns.c (hash_string): New function, taken from sxhash_string.
9622 Do not discard information about ASCII character case; this
9623 discarding is no longer needed.
9624 (sxhash-string): Use it. Change sig to match it. Caller changed.
9625 * lisp.h: Declare it.
9626 * lread.c (hash_string): Remove, since we now use fns.c's version.
9627 The fns.c version returns a wider integer if --with-wide-int is
9628 specified, so this should help the quality of the hashing a bit.
9629
9630 * emacs.c: Integer overflow minor fix.
9631 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9632 Define only if GNU_LINUX.
9633 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9634
9635 * dispnew.c: Integer signedness and overflow fixes.
9636 Remove unnecessary forward decls, that were a maintenance hassle.
9637 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9638 All uses changed.
9639 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9640 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9641 (prepare_desired_row, line_draw_cost):
9642 Use int, not unsigned, where either works.
9643 (save_current_matrix, restore_current_matrix):
9644 Use ptrdiff_t, not size_t, where either works.
9645 (init_display): Check for overflow more accurately, and without
9646 relying on undefined behavior.
9647
9648 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9649 Remove, replacing with the new symbols in lisp.h. All uses changed.
9650 * fileio.c (make_temp_name):
9651 * filelock.c (lock_file_1, lock_file):
9652 * xdisp.c (message_dolog):
9653 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9654 Use pMd etc. instead.
9655 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9656 replacing the pWIDE etc. symbols removed from editfns.c.
9657
9658 * keyboard.h (num_input_events): Now uintmax_t.
9659 This is (very slightly) less likely to mess up due to wraparound.
9660 All uses changed.
9661
9662 * buffer.c: Integer signedness fixes.
9663 (alloc_buffer_text, enlarge_buffer_text):
9664 Use ptrdiff_t rather than size_t when either will do, as we prefer
9665 signed integers.
9666
9667 * alloc.c: Integer signedness and overflow fixes.
9668 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9669 (__malloc_size_t): Default to size_t, not to int.
9670 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9671 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9672 Prefer ptrdiff_t to size_t when either would do, as we prefer
9673 signed integers.
9674 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9675 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9676 Now const. Initialize with values that are in range even if char
9677 is signed.
9678 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9679 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9680 These functions do the right thing with sizes > 2**32.
9681 (check_depth): Now ptrdiff_t, not int.
9682 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9683 Adjust to new way of storing sizes. Check for size overflow bugs
9684 in rest of code.
9685 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9686 slightly wrong anyway, as it missed one instance of
9687 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9688 (refill_memory_reserve): Omit needless cast to size_t.
9689 (mark_object_loop_halt): Mark as externally visible.
9690
9691 * xselect.c: Integer signedness and overflow fixes.
9692 (Fx_register_dnd_atom, x_handle_dnd_message):
9693 Use ptrdiff_t, not size_t, since we prefer signed.
9694 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9695 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9696 x_dnd_atoms_size and x_dnd_atoms_length.
9697
9698 * doprnt.c: Prefer signed to unsigned when either works.
9699 * eval.c (verror):
9700 * doprnt.c (doprnt):
9701 * lisp.h (doprnt):
9702 * xdisp.c (vmessage):
9703 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9704 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9705 prefer signed arithmetic to avoid comparison confusion.
9706 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9707 but is a bit tricky.
9708
9709 Assume freestanding C89 headers, string.h, stdlib.h.
9710 * data.c, doprnt.c, floatfns.c, print.c:
9711 Include float.h unconditionally.
9712 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9713 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9714 * regex.c: Likewise for stddef.h, string.h.
9715 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9716 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9717 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9718 (STDC_HEADERS): Remove obsolete defines.
9719 * sysdep.c: Include limits.h unconditionally.
9720
9721 Assume support for memcmp, memcpy, memmove, memset.
9722 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9723 * regex.c (memcmp, memcpy):
9724 Remove; we assume C89 now.
9725
9726 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9727 (__malloc_safe_bcopy): Remove; no longer needed.
9728
9729 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9730 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9731 well either way, and we prefer signed to unsigned.
9732
9733 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9734
9735 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9736 closes the connection while we're reading (bug#9182).
9737
9738 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9739
9740 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9741 are specified (Bug#9168).
9742
9743 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9744
9745 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9746 Found by GCC static checking and --with-wide-int on a 32-bit host.
9747
9748 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9749
9750 * xdisp.c (compute_display_string_pos): Fix logic of caching
9751 previous display string position. Initialize cached_prev_pos to
9752 -1. Fixes slow-down at the beginning of a buffer.
9753
9754 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9755
9756 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9757 for attrs[LFACE_FONTSET_INDEX].
9758
9759 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9760
9761 * xml.c (parse_region): Remove unused local
9762 that was recently introduced.
9763
9764 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9765
9766 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9767 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9768
9769 * xdisp.c (move_it_in_display_line_to): Record the best matching
9770 position for TO_CHARPOS while scanning the line, and restore it on
9771 exit if none of the characters scanned was an exact match.
9772 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9773 when exact match is impossible due to invisible text, and the
9774 lines are truncated.
9775
9776 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9777
9778 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9779 for OSX >= 10.7.
9780
9781 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9782
9783 Fix a significant slow-down of cursor motion with C-n, C-p,
9784 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9785 auto-repeat under bidi redisplay in fontified buffers.
9786 * xdisp.c (compute_stop_pos_backwards): New function.
9787 (next_element_from_buffer): Call compute_stop_pos_backwards to
9788 find a suitable prev_stop when we find ourselves before
9789 base_level_stop.
9790 (reseat): Don't look for prev_stop, as that could mean a very long
9791 run.
9792 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9793 <cached_disp_overlay_modiff>: Cache for last found display string
9794 position.
9795 (compute_display_string_pos): Return the cached position if asked
9796 about the same buffer in the same area of character positions, and
9797 the buffer wasn't changed since the time the display string
9798 position was cached.

9800 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9801
9802 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9803 is an integer, which is important for empty lines. (Bug#9149)
9804
9805 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9806
9807 * frame.c (Fmodify_frame_parameters): In tty case, update the
9808 default face if necessary (Bug#4238).
9809
9810 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9811
9812 * editfns.c (Fstring_to_char): No need to explain what a character
9813 is in the docstring (Bug#6576).
9814
9815 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9816
9817 * xml.c (parse_region): Make sure we always return a tree.
9818
9819 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9820
9821 * xml.c (parse_region): If a document contains only comments,
9822 return that, too.
9823
9824 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9825
9826 * xml.c (make_dom): Return comments, too.
9827
9828 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9829
9830 Port to OpenBSD.
9831 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9832 and the surrounding thread.
9833 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9834 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9835 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9836 timer goes off.
9837 * s/openbsd.h (BROKEN_SIGIO): Define.
9838 * unexelf.c (unexec) [__OpenBSD__]:
9839 Don't update the .mdebug section of the Alpha COFF symbol table.
9840
9841 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9842
9843 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9844 (bug#8460).
9845
9846 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9847
9848 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9849 This fixes some race conditions on the permissions of any newly
9850 created file.
9851
9852 * alloc.c (valid_pointer_p): Use pipe, not open.
9853 This fixes some permissions issues when debugging.
9854
9855 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9856 If fchown fails to set both uid and gid, try to set just gid,
9857 as that is sometimes allowed. Adjust the file's mode to eliminate
9858 setuid or setgid bits that are inappropriate if fchown fails.
9859
9860 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9861
9862 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9863 to compare Lisp_Objects.
9864 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9865 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9866 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9867
9868 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9869
9870 * lread.c (read_integer): Unread even EOF character.
9871 (read1): Likewise. Properly record start position of symbol.
9872
9873 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9874 symbol character follows.
9875
9876 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9877
9878 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9879 This works around a problem with the previous change to Fcopy_file.
9880 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9881 and without this change, GCC might complain about discarding
9882 fchown's return value.
9883
9884 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9885
9886 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9887
9888 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9889
9890 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9891
9892 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9893
9894 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9895 it's used from the C level.
9896
9897 * process.c: Use the same condition for POLL_FOR_INPUT in both
9898 keyboard.c and process.c (bug#1858).
9899
9900 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9901
9902 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9903 (Fgnutls_boot): Use it.
9904
9905 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9906
9907 * doc.c (Fsubstitute_command_keys): Revert last change.
9908
9909 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9910
9911 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9912 quotes the next character, and doesn't affect other longer
9913 sequences (bug#8935).
9914
9915 * lread.c (syms_of_lread): Clarify that is isn't only
9916 `eval-buffer' and `eval-defun' that's affected by
9917 `lexical-binding' (bug#8460).
9918
9919 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9920
9921 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9922 bidi redisplay when a line includes both an image and is truncated.
9923
9924 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9925
9926 Fix minor problems found by static checking.
9927 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9928 (elsz): Now a signed constant, not a size_t var. We prefer signed
9929 types to unsigned, to avoid integer comparison confusion. Without
9930 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9931 "cannot optimize loop, the loop counter may overflow", a symptom
9932 of the confusion.
9933 * indent.c (Fvertical_motion): Mark locals as initialized.
9934 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9935
9936 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9937
9938 * search.c (Fre_search_backward): Mention `case-fold-search' in
9939 all the re_search_* functions (bug#8138).
9940
9941 * keyboard.c (Fopen_dribble_file): Document when the file is
9942 closed (bug#8056).
9943
9944 2011-07-14 Eli Zaretskii <eliz@gnu.org>
9945
9946 * bidi.c (bidi_dump_cached_states): Fix format of displaying
9947 bidi_cache_idx.
9948
9949 Support bidi reordering of display and overlay strings.
9950 * xdisp.c (compute_display_string_pos)
9951 (compute_display_string_end): Accept additional argument STRING.
9952 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
9953 (reseat_to_string): Initialize bidi_it->string.s and
9954 bidi_it->string.schars.
9955 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
9956 NULL (avoids a crash in bidi_paragraph_init).
9957 Initialize itb.string.lstring.
9958 (init_iterator): Call bidi_init_it only of a valid
9959 buffer position was specified. Initialize paragraph_embedding to
9960 L2R.
9961 (reseat_to_string): Initialize the bidi iterator.
9962 (display_string): If we need to ignore text properties of
9963 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9964 original value of -1 will not work with bidi.)
9965 (compute_display_string_pos): First arg is now struct
9966 `text_pos *'; all callers changed. Support display properties on
9967 Lisp strings.
9968 (compute_display_string_end): Support display properties on Lisp
9969 strings.
9970 (init_iterator, reseat_1, reseat_to_string): Initialize the
9971 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9972 when iterating on a string not from display properties).
9973 (compute_display_string_pos, compute_display_string_end):
9974 Fix calculation of the object to scan. Fixes an error when using
9975 arrow keys.
9976 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9977 base_level_stop; instead, set base_level_stop to BEGV.
9978 Fixes crashes in vertical-motion.
9979 (next_element_from_buffer): Improve commentary for when
9980 the iterator is before prev_stop.
9981 (init_iterator): Initialize bidi_p from the default value of
9982 bidi-display-reordering, not from buffer-local value. Use the
9983 buffer-local value only if initializing for buffer iteration.
9984 (handle_invisible_prop): Support invisible properties on strings
9985 that are being bidi-reordered.
9986 (set_iterator_to_next): Support bidi reordering of C strings and
9987 Lisp strings.
9988 (next_element_from_string): Support bidi reordering of Lisp
9989 strings.
9990 (handle_stop_backwards): Support Lisp strings as well.
9991 (display_string): Support display of R2L glyph rows.
9992 Use IT_STRING_CHARPOS when displaying from a Lisp string.

9994 here.
9995 (reseat_to_string): Initialize it->bidi_p for strings here.
9996 (next_element_from_string, next_element_from_c_string)
9997 (next_element_from_buffer): Add xassert's for correspondence
9998 between IT's object being iterated and it->bidi_it.string
9999 structure.
10000 (face_before_or_after_it_pos): Support bidi iteration.
10001 (next_element_from_c_string): Handle the case of the first string
10002 character that is not the first one in the visual order.
10003 (get_visually_first_element): New function, refactored from common
10004 parts of next_element_from_buffer, next_element_from_string, and
10005 next_element_from_c_string.
10006 (tool_bar_lines_needed, redisplay_tool_bar)
10007 (display_menu_bar): Force left-to-right direction. Add a FIXME
10008 comment for making that be controlled by a user option.
10009 (push_it, pop_it): Save and restore the state of the
10010 bidi iterator. Save and restore the bidi_p flag.

10018 iterator for displaying display or overlay strings.
10019 (forward_to_next_line_start): Don't use the shortcut if
10020 bidi-iterating.
10021 (back_to_previous_visible_line_start): If handle_display_prop
10022 pushed the iterator stack, restore the internal state of the bidi
10023 iterator by calling bidi_pop_it same number of times.
10024 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
10025 and we are bidi-iterating, don't decrement the iterator position;
10026 instead, set the first_elt flag in the bidi iterator, to produce
10027 the same effect.
10028 (reseat_1): Remove redundant setting of string_from_display_prop_p.
10029 (push_display_prop): xassert that we are iterating a buffer.
10030 (push_it, pop_it): Save and restore paragraph_embedding member.

10040 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
10041 (pop_it): Call iterate_out_of_display_property only if we are
10042 popping after iteration over a string that came from a display
10043 property. Fix a typo in popping stretch info. Add an assertion
10044 for verifying that the iterator position is in sync with the bidi
10045 iterator.
10046 (handle_single_display_spec, get_overlay_strings_1)
10047 (push_display_prop): Fix initialization of paragraph direction for
10048 string when that of the parent object is not yet determined.
10049 (reseat_1): Call bidi_init_it to resync the bidi
10050 iterator with IT's position. (Bug#7616)
10051 (find_row_edges): If ROW->start.pos gives position
10052 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
10053 (handle_stop, back_to_previous_visible_line_start, reseat_1):
10054 Reset the from_disp_prop_p flag.
10055 (SAVE_IT, RESTORE_IT): New macros.

10061 saving a temporary copy of the iterator and restoring it back.
10062 (back_to_previous_visible_line_start, reseat_1)
10063 (init_iterator): Empty the bidi cache "stack".
10064 (move_it_in_display_line_to): If iterator ended up at
10065 EOL, but we never saw any buffer positions smaller than
10066 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
10067 motion in bidi-reordered lines.
10068 (move_it_in_display_line_to): Record prev_method and prev_pos
10069 immediately before the call to set_iterator_to_next. Fixes cursor
10070 motion in bidi-reordered lines with stretch glyphs and strings
10071 displayed in margins. (Bug#8133) (Bug#8867)
10072 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
10073 TO_CHARPOS.
10074 (pos_visible_p): Support positions in bidi-reordered lines.
10075 Save and restore bidi cache.
10076

10087 (bidi_move_to_visually_next): Compare cache index with
10088 bidi_cache_start rather than with zero.
10089 (bidi_fetch_char): Accept new argument STRING; all callers
10090 changed. Support iteration over a string. Support strings with
10091 display properties. Support unibyte strings. Fix the type of
10092 `len' according to what STRING_CHAR_AND_LENGTH expects.

10113 (bidi_initialize): Initialize the bidi cache start stack pointer.
10114 (bidi_cache_ensure_space): New function, refactored from part of

10122 is valid if it's going to be used.
10123 (bidi_shelve_cache, bidi_unshelve_cache): New functions.

10127 (bidi_find_other_level_edge, bidi_cache_start_stack):
10128 All variables related to cache indices are now EMACS_INT.
10129
10130 * dispextern.h (struct bidi_string_data): New structure.
10131 (struct bidi_it): New member `string'. Make flag members be 1-bit
10132 fields, and put them last in the struct.

10169
10170 * gnutls.c (init_gnutls_functions): Honor gnutls_log_level (bug#9059).

10180 (Qx_sent_selection_functions): New vars.
10181 (syms_of_xselect): DEFSYM them.
10182 (x_handle_selection_request): Pass Qx_sent_selection_functions
10183 rather than Vx_sent_selection_functions to Frun_hook_with_args.
10184 (x_handle_selection_clear,x_clear_frame_selections):
10185 Pass Qx_lost_selection_functions rather than
10186 Vx_lost_selection_functions to Frun_hook_with_args.
10187
10188 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
10189
10190 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
10191 The old code sometimes used this field without initializing it.
10192
10193 * alloc.c (gc_sweep): Don't read past end of array.
10194 In theory, the old code could also have corrupted Emacs internals,
10195 though it'd be very unlikely.

10498
10499 Random fixes. E.g., (random) never returned negative values.
10500 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10501 subseconds part to the entropy, as that's a bit more random.
10502 Prefer signed to unsigned, since the signedness doesn't matter and
10503 in general we prefer signed. When given a limit, use a
10504 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10505 latter isn't right if USE_2_TAGS_FOR_INTS.
10506 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10507 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10518
10519 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.

10531 error be more correct.

10547 Qgnutls_bootprop_verify_error (which is no longer used).
10548
10549 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
10550 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

10651
10652 * eval.c (struct backtrace): Simplify and port the data structure.
10653 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10654 signed bit field, as this assumption is not portable and it makes
10655 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10656 "char debug_on_exit : 1" as this is not portable either; instead,
10657 use the portable "unsigned int debug_on_exit : 1". Remove unused
10658 member evalargs. Remove obsolete comments about cc bombing out.

10695 clearly which files are directly included by each source file,
10696 and not through other includes.
10697
10698 2011-06-27 Martin Rudalics <rudalics@gmx.at>
10699

10741
10742 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling

10744 called at ZV.
10745
10746 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
10747
10748 * process.c (wait_reading_process_output): Bypass select if

10830 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10831 for sizes. Check for string overflow more accurately.

10848 (read1): Check for integer overflow in radices, and in
10849 read-circle numbers.
10850 (read_escape): Avoid int overflow.
10851 (Fload, openp, read_buffer_size, read1)
10852 (substitute_object_recurse, read_vector, read_list, map_obarray):

10874
10875 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10876 The following patches are for when GLYPH_DEBUG && !XASSERT.
10877 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10878 * dispnew.c (flush_stdout):
10879 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10880 Mark as externally visible.
10881 * dispnew.c (check_window_matrix_pointers): Now static.

10891 Now static.
10892 (debug_method_add): Use va_list and vsprintf rather than relying
10893 on undefined behavior with wrong number of arguments.
10894 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10895 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10896 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10897 since we're not interested in debugging glyphs with old libraries.
10898 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10899 GCC 4.6.0's static checking.
10900

10985 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10986 Reformulate so as not to need the command string.
10987 Invoke gzip -cd rather than gunzip, as it's more portable.
10988 (lock_info_type, lock_file_1, lock_file):
10989 Don't assume pid_t and time_t fit in unsigned long.
10990 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10991 (current_lock_owner): Prefer signed type for sizes.
10992 Use memcpy, not strncpy, where memcpy is what is really wanted.
10993 Don't assume (via atoi) that time_t and pid_t fit in int.
10994 Check for time_t and/or pid_t out of range, e.g., via a network share.
10995 Don't alloca where an auto var works fine.
10996
10997 * fileio.c: Fix some integer overflow issues.
10998 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10999 Don't assume string length fits in int.
11000 (directory_file_name): Don't assume string length fits in long.
11001 (make_temp_name): Don't assume pid fits in int, or that its print
11002 length is less than 20.
11003
11004 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
11005
11006 * coding.c (make_subsidiaries): Don't assume string length fits in int.
11007
11008 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
11009
11010 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
11011 We prefer signed integers, even for size calculations.
11012
11013 * emacs.c: Don't assume string length fits in 'int'.
11014 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
11015 (main): Don't invoke strlen when not needed.
11016
11017 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
11018 (XD_DEBUG_MESSAGE): Don't waste a byte.
11019
11020 * callproc.c (getenv_internal_1, getenv_internal)
11021 (Fgetenv_internal):
11022 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
11023
11024 * lread.c (invalid_syntax): Omit length argument.
11025 All uses changed. This doesn't fix a bug, but it simplifies the
11026 code away from its former Hollerith-constant appearance, and it's
11027 one less 'int' to worry about when looking at integer-overflow issues.
11028 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
11029
11030 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
11031 This didn't break anything, but it didn't help either.
11032 It's confusing to put a bogus integer in a place where the actual
11033 value does not matter.
11034 (LIST_END_P): Remove unused macro and its bogus comment.
11035 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
11036
11037 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
11038 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
11039 implementation.
11040 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
11041 We prefer signed types, and the value cannot exceed the EMACS_INT
11042 range anyway (because otherwise the length would not be representable).
11043 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
11044 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
11045 This avoids a GCC warning when WIDE_EMACS_INT.
11046
11047 * indent.c (sane_tab_width): New function.
11048 (current_column, scan_for_column, Findent_to, position_indentation)
11049 (compute_motion): Use it. This is just for clarity.
11050 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
11051
11052 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
11053
11054 * lisp.h (lint_assume): New macro.
11055 * composite.c (composition_gstring_put_cache):
11056 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
11057
11058 * editfns.c, insdel.c:
11059 Omit unnecessary forward decls, to simplify future changes.
11060
11061 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
11062
11063 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
11064
11065 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
11066 Use much-faster test for byte-length change.
11067 Don't assume string byte-length fits in 'int'.
11068 Check that character arg fits in 'int'.
11069 (mapcar1): Declare byte as byte, for clarity.
11070
11071 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
11072
11073 * fns.c (concat): Catch string overflow earlier.
11074 Do not rely on integer wraparound.
11075
11076 * dispextern.h (struct it.overlay_strings_charpos)
11077 (struct it.selective): Now EMACS_INT, not int.
11078 * xdisp.c (forward_to_next_line_start)
11079 (back_to_previous_visible_line_start)
11080 (reseat_at_next_visible_line_start, next_element_from_buffer):
11081 Don't arbitrarily truncate the value of 'selective' to int.
11082
11083 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
11084
11085 * composite.c: Don't truncate sizes to 'int'.
11086 (composition_gstring_p, composition_reseat_it)
11087 (composition_adjust_point): Use EMACS_INT, not int.
11088 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
11089 not EMACS_UINT, for indexes.
11090
11091 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
11092
11093 * buffer.c: Include <verify.h>.
11094 (struct sortvec.priority, struct sortstr.priority):
11095 Now EMACS_INT, not int.
11096 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
11097 (struct sortstr.size, record_overlay_string)
11098 (struct sortstrlist.size, struct sortlist.used):
11099 Don't truncate size to int.
11100 (record_overlay_string): Check for size-calculation overflow.
11101 (init_buffer_once): Check at compile-time, not run-time.
11102
11103 2011-06-22 Jim Meyering <meyering@redhat.com>
11104
11105 Don't leak an XBM-image-sized buffer
11106 * image.c (xbm_load): Free the image buffer after using it.
11107
11108 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
11109
11110 Port to Sun C.
11111 * composite.c (find_automatic_composition): Omit needless 'return 0;'
11112 that Sun C diagnosed.
11113 * fns.c (secure_hash): Fix pointer signedness issue.
11114 * intervals.c (static_offset_intervals): New function.
11115 (offset_intervals): Use it.
11116
11117 2011-06-21 Leo Liu <sdl.web@gmail.com>
11118
11119 * deps.mk (fns.o):
11120 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
11121 sha512.h.
11122
11123 * fns.c (secure_hash): Rename from crypto_hash_function and change
11124 the first arg to accept symbols.
11125 (Fsecure_hash): New primitive.
11126 (syms_of_fns): New symbols.
11127
11128 2011-06-20 Deniz Dogan <deniz@dogan.se>
11129
11130 * process.c (Fset_process_buffer): Clarify return value in
11131 docstring.
11132
11133 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
11134
11135 * dispnew.c (add_window_display_history): Use BVAR.
11136
11137 * xdisp.c (debug_method_add): Use BVAR.
11138 (check_window_end, dump_glyph_matrix, dump_glyph)
11139 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
11140
11141 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
11142 Likewise.
11143
11144 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
11145 check till after the cache is created in init_frame_faces.
11146
11147 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
11148
11149 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
11150
11151 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
11152
11153 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
11154 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
11155 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
11156
11157 Improve buffer-overflow checking (Bug#8873).
11158 * fileio.c (Finsert_file_contents):
11159 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
11160 Remove the old (too-loose) buffer overflow checks.
11161 They weren't needed, since make_gap checks for buffer overflow.
11162 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
11163 The old code merely checked for Emacs fixnum overflow, and relied
11164 on undefined (wraparound) behavior. The new code avoids undefined
11165 behavior, and also checks for ptrdiff_t and/or size_t overflow.
11166
11167 * editfns.c (Finsert_char): Don't dump core with very negative counts.
11168 Tune. Don't use wider integers than needed. Don't use alloca.
11169 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
11170
11171 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
11172
11173 * insdel.c, lisp.h (buffer_overflow): New function.
11174 (insert_from_buffer_1, replace_range, replace_range_2):
11175 * insdel.c (make_gap_larger):
11176 * editfns.c (Finsert_char):
11177 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
11178
11179 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
11180
11181 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
11182
11183 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
11184
11185 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
11186 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
11187
11188 * fileio.c: Don't assume EMACS_INT fits in off_t.
11189 (emacs_lseek): New static function.
11190 (Finsert_file_contents, Fwrite_region): Use it.
11191 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
11192
11193 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
11194
11195 * fns.c: Don't overflow int when computing a list length.
11196 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
11197 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
11198 truncation on 64-bit hosts. Check for QUIT every
11199 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
11200 faster and is responsive enough.
11201 (Flength): Report an error instead of overflowing an integer.
11202 (Fsafe_length): Return a float if the value is not representable
11203 as a fixnum. This shouldn't happen except in contrived situations.
11204 (Fnthcdr, Fsort): Don't assume list length fits in int.
11205 (Fcopy_sequence): Don't assume vector length fits in int.
11206
11207 * alloc.c: Check that resized vectors' lengths fit in fixnums.
11208 (header_size, word_size): New constants.
11209 (allocate_vectorlike): Don't check size overflow here.
11210 (allocate_vector): Check it here instead, since this is the only
11211 caller of allocate_vectorlike that could cause overflow.
11212 Check that the new vector's length is representable as a fixnum.
11213
11214 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11215 The previous code was bogus. For example, next_almost_prime (32)
11216 returned 39, which is undesirable as it is a multiple of 3; and
11217 next_almost_prime (24) returned 25, which is a multiple of 5 so
11218 why was the code bothering to check for multiples of 7?
11219
11220 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11221
11222 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11223
11224 Variadic C functions now count arguments with ptrdiff_t.
11225 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11226 Back then I didn't know that the Emacs coding style prefers signed int.
11227 Also, in the meantime I found a few more instances where arguments
11228 were being counted with int, which may truncate counts on 64-bit
11229 machines, or EMACS_INT, which may be unnecessarily wide.
11230 * lisp.h (struct Lisp_Subr.function.aMANY)
11231 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11232 Arg counts are now ptrdiff_t, not size_t.
11233 All variadic functions and their callers changed accordingly.
11234 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11235 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11236 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11237 * callint.c (Fcall_interactively): Check arg count for overflow,
11238 to avoid potential buffer overrun. Use signed char, not 'int',
11239 for 'varies' array, so that we needn't bother to check its size
11240 calculation for overflow.
11241 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11242 * eval.c (apply_lambda):
11243 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11244 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11245 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11246
11247 * callint.c (Fcall_interactively): Don't use index var as event count.
11248
11249 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11250 * mem-limits.h (SIZE): Remove; no longer used.
11251
11252 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11253
11254 Remove unnecessary casts.
11255 * xterm.c (x_term_init):
11256 * xfns.c (x_set_border_pixel):
11257 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11258 These aren't needed now that we assume ANSI C.
11259
11260 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11261 It's more likely to cause problems (due to unsigned overflow)
11262 than to cure them.
11263
11264 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11265
11266 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11267
11268 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11269
11270 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11271
11272 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11273
11274 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11275
11276 GLYPH_CODE_FACE returns EMACS_INT, not int.
11277 * dispextern.h (merge_faces):
11278 * xfaces.c (merge_faces):
11279 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11280 Don't assume EMACS_INT fits in int.
11281
11282 * character.h (CHAR_VALID_P): Remove unused parameter.
11283 * fontset.c, lisp.h, xdisp.c: All uses changed.
11284
11285 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11286
11287 * fns.c (concat): Minor tuning based on overflow analysis.
11288 This doesn't fix any bugs. Use int to hold character, instead
11289 of constantly refetching from Emacs object. Use XFASTINT, not
11290 XINT, for value known to be a character. Don't bother comparing
11291 a single byte to 0400, as it's always less.
11292
11293 * floatfns.c (Fexpt):
11294 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11295
11296 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11297 for characters.
11298
11299 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11300
11301 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11302 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11303 incorrectly succeed when S was a string, because 4294967386 was
11304 truncated before it was used.
11305
11306 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11307 Otherwise, an out-of-range integer could cause undefined behavior
11308 on a 64-bit host.
11309
11310 * composite.c: Use int, not EMACS_INT, for characters.
11311 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11312 EMACS_INT, for values that are known to be in character range.
11313 This doesn't fix any bugs but is the usual style inside Emacs and
11314 may generate better code on 32-bit machines.
11315
11316 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11317 This is for reasons similar to the recent CHAR_STRING fix.
11318 * charset.c (Fencode_char): Check that character arg is actually
11319 a character. Pass an int to ENCODE_CHAR.
11320 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11321 wider than 'int', as a compile-time check to prevent future regressions
11322 in this area.
11323
11324 * character.c (char_string): Remove unnecessary casts.
11325
11326 Make sure a 64-bit char is never passed to CHAR_STRING.
11327 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11328 by silently ignoring the top 32 bits, allowing some values
11329 that were far too large to be valid characters.
11330 * character.h: Include <verify.h>.
11331 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11332 arguments are no wider than unsigned, as a compile-time check
11333 to prevent future regressions in this area.
11334 * data.c (Faset):
11335 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11336 (Fsubst_char_in_region):
11337 * fns.c (concat):
11338 * xdisp.c (decode_mode_spec_coding):
11339 Adjust to CHAR_STRING's new requirement.
11340 * editfns.c (Finsert_char, Fsubst_char_in_region):
11341 * fns.c (concat): Check that character args are actually
11342 characters. Without this test, these functions did the wrong
11343 thing with wildly out-of-range values on 64-bit hosts.
11344
11345 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11346 These casts should not be needed on 32-bit hosts, either.
11347 * keyboard.c (read_char):
11348 * lread.c (Fload): Remove casts to unsigned.
11349
11350 * lisp.h (UNSIGNED_CMP): New macro.
11351 This fixes comparison bugs on 64-bit hosts.
11352 (ASCII_CHAR_P): Use it.
11353 * casefiddle.c (casify_object):
11354 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11355 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11356 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11357 * dispextern.h (FACE_FROM_ID):
11358 * keyboard.c (read_char): Use UNSIGNED_CMP.
11359
11360 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11361 not to EMACS_INT, to avoid GCC warning.
11362
11363 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11364
11365 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11366 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11367 isn't needed on 32-bit machines.
11368
11369 * buffer.c (Fgenerate_new_buffer_name):
11370 Use EMACS_INT for count, not int.
11371 (advance_to_char_boundary): Return EMACS_INT, not int.
11372
11373 * data.c (Qcompiled_function): Now static.
11374
11375 * window.c (window_body_lines): Now static.
11376
11377 * image.c (gif_load): Rename local to avoid shadowing.
11378
11379 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11380 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11381 * alloc.c (make_save_value): Integer argument is now of type
11382 ptrdiff_t, not int.
11383 (mark_object): Use ptrdiff_t, not int.
11384 * lisp.h (pD): New macro.
11385 * print.c (print_object): Use it.
11386

11391 (total_intervals, total_strings, total_free_strings):
11392 Now EMACS_INT, not int. All uses changed.
11393 (Fgarbage_collect): Compute overall total using a double, so that
11394 integer overflow is less likely to be a problem. Check for overflow
11395 when converting back to an integer.
11396 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11397 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11398 These were 'int' variables that could overflow on 64-bit hosts;
11399 they were never used, so remove them instead of repairing them.
11400 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11401 (inhibit_garbage_collection): Set gc_cons_threshold to max value.

11415 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11416 The definition here is exact; the one in lisp.h was approximate.
11417 (allocate_string_data): Check for string overflow. This catches
11418 some instances we weren't catching before. Also, it catches
11419 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11420 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11421 and ptrdiff_t and EMACS_INT are both 64 bits.
11422
11423 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11424 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

11845 Use STRING_BYTES_MAX, not MOST_POSITIVE_FIXNUM,
11846 since they may not be the same number.

11853 All uses changed.
11854 (slurp_file): Check that file size fits in both size_t (for

11858 if b->modtime has its maximal value.
11859
11860 * dired.c (Ffile_attributes): Don't assume EMACS_INT has >32 bits.

11872 * ftfont.c (ftfont_spec_pattern):
11873 * keymap.c (access_keymap, silly_event_symbol_error):
11874 XUINT -> XFASTINT, since the integer must be nonnegative.
11875 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
11876 since it makes no difference and we prefer signed.
11877 * keyboard.c (record_char): Use XUINT when all the neighbors do.
11878 (access_keymap): NATNUMP -> INTEGERP, since the integer must be
11879 nonnegative.

11926
11927 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
11928
11929 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
11930 Do not assume that spare memory exists; that assumption is valid
11931 only if SYSTEM_MALLOC.
11932 (LARGE_REQUEST): New macro, so that the issue of large requests
11933 is separated from the issue of spare memory.
11934

11993 display string.
11994 (bidi_paragraph_init, bidi_resolve_explicit_1)
11995 (bidi_level_of_next_char): Call bidi_fetch_char and
11996 bidi_fetch_char_advance instead of FETCH_CHAR and
11997 FETCH_CHAR_ADVANCE.
11998 (bidi_init_it): Initialize new members.
11999 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
12000 definitions.
12001 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
12002 instead of using explicit *_CHAR codes.
12003 (bidi_resolve_explicit, bidi_resolve_weak):
12004 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
12005 bidirectional text is supported only in multibyte buffers.
12006 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
12007 it to initialize the frame_window_p member of struct bidi_it.

12014 were just reseat()'ed to a new position.
12015
12016 * xdisp.c (set_cursor_from_row): Set start and stop points
12017 according to the row's direction when priming the loop that looks
12018 for the glyph on which to display cursor.
12019 (single_display_spec_intangible_p): Function deleted.
12020 (display_prop_intangible_p): Reimplement to call
12021 handle_display_spec instead of single_display_spec_intangible_p.
12022 Accept 3 additional arguments needed by handle_display_spec.
12023 This fixes incorrect cursor motion across display property with complex
12024 values: lists, `(when COND...)' forms, etc.
12025 (single_display_spec_string_p): Support property values that are
12026 lists with the argument STRING its top-level element.
12027 (display_prop_string_p): Fix the condition for processing a
12028 property that is a list to be consistent with handle_display_spec.
12029 (handle_display_spec): New function, refactored from the
12030 last portion of handle_display_prop.
12031 (compute_display_string_pos): Accept additional argument

12038 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
12039 frame_window_p members of struct bidi_it.
12040 (compute_display_string_pos, compute_display_string_end):

12045
12046 * keyboard.c (adjust_point_for_property): Adjust the call to
12047 display_prop_intangible_p to its new signature.
12048
12049 * dispextern.h (struct bidi_it): New member frame_window_p.
12050 (bidi_init_it): Update prototypes.

12064
12065 * gnutls.c: Use Emacs's memory allocators.
12066 Without this change, the gnutls library would invoke malloc etc.
12067 directly, which causes problems on non-SYNC_INPUT hosts, and which
12068 runs afoul of improving memory_full behavior. (Bug#8761)
12069 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
12070 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
12071 xfree instead of the default malloc, realloc, free.
12072 (Fgnutls_boot): No need to check for memory allocation failure,
12073 since xmalloc does that for us.
12074

12088 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
12089 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
12090 (Fsxhash, Fgethash, Fputhash, Fmaphash):

12092 (xpm_put_color_table_h):
12093 * lisp.h (struct Lisp_Hash_Table):
12094 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
12095 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
12096 for hashes and hash indexes, instead of 'unsigned' and 'int'.
12097 * alloc.c (allocate_vectorlike):
12098 Check for overflow in vector size calculations.
12099 * ccl.c (ccl_driver):
12100 Check for overflow when converting EMACS_INT to int.
12101 * fns.c, image.c: Remove unnecessary static decls that would otherwise
12102 need to be updated by these changes.
12103 * fns.c (make_hash_table, maybe_resize_hash_table):
12104 Check for integer overflow with large hash tables.
12105 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
12106 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
12107 (SXHASH_REDUCE): New macro.
12108 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
12109 Use it instead of discarding useful hash info with large hash values.
12110 (sxhash_float): New function.
12111 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
12112 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
12113 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
12114 Rewrite to use FIXNUM_BITS, as this simplifies things.
12115 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
12116 Adjust signatures to match updated version of code.
12117 (consing_since_gc): Now EMACS_INT, since a single hash table can
12118 use more than INT_MAX bytes.

12168
12169 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
12170 syms_of_callproc does the same thing. Remove test for
12171 "initialized", do it in the caller.
12172 * emacs.c (main): Avoid calling set_initial_environment when dumping.
12173
12174 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
12175
12176 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
12177 (read_minibuf): Use get_minibuffer.
12178 (syms_of_minibuf): Use DEFSYM.
12179 (Qmetadata): New var.
12180 * data.c (Qbuffer): Don't make it static.
12181 (syms_of_data): Use DEFSYM.
12182
12183 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12184
12185 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
12186 (CCL_CODE_MIN): New macro.
12187
12188 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
12189
12190 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
12191
12192 * eval.c (Qdebug): Now static.
12193 * lisp.h (Qdebug): Remove decl. This reverts a part of the
12194 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
12195 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
12196
12197 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12198
12199 * image.c: Various fixes to ImageMagick code comments.
12200 (Fimagemagick_types): Doc fix.
12201
12202 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
12203
12204 Minor fixes prompted by GCC 4.6.0 warnings.
12205
12206 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12207
12208 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12209 (x_clipboard_manager_save_all): Move extern decl to ...
12210 * xterm.h: ... here, so that it can be checked for consistency.
12211
12212 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12213
12214 * xselect.c (x_clipboard_manager_save_frame)
12215 (x_clipboard_manager_save_all): New functions.
12216 (Fx_clipboard_manager_save): Lisp function deleted.
12217
12218 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12219 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12220
12221 * xterm.h: Update prototype.
12222
12223 2011-05-28 William Xu <william.xwl@gmail.com>
12224
12225 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12226 exiting (Bug#8239).
12227
12228 2011-05-28 Jim Meyering <meyering@redhat.com>
12229
12230 Avoid a sign-extension bug in crypto_hash_function.
12231 * fns.c (to_uchar): Define.
12232 (crypto_hash_function): Use it to convert some newly-signed
12233 variables to unsigned, to avoid sign-extension bugs. For example,
12234 without this change, (md5 "truc") would evaluate to
12235 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12236 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12237 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12238
12239 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12240
12241 Integer overflow fixes.
12242
12243 * dbusbind.c: Serial number integer overflow fixes.
12244 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12245 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12246 to hold a serial number that is too large for a fixnum.
12247 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12248 Check for serial numbers out of range. Decode any serial number
12249 that was so large that it became a float. (Bug#8722)
12250
12251 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12252 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12253 Use XFASTINT rather than XUINT when numbers are nonnegative.
12254 (xd_append_arg, Fdbus_method_return_internal):
12255 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12256 arguments, check that Lisp number is nonnegative, rather than
12257 silently wrapping negative numbers around. (Bug#8722)
12258 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12259 (Bug#8722)
12260
12261 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12262
12263 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12264
12265 ccl: Add integer overflow checks.
12266 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12267 (IN_INT_RANGE): New macros.
12268 (ccl_driver): Use them to check for integer overflow when
12269 decoding a CCL program. Many of the new checks are whether XINT (x)
12270 fits in int; it doesn't always, on 64-bit hosts. The new version
12271 doesn't catch all possible integer overflows, but it's an
12272 improvement. (Bug#8719)
12273
12274 * alloc.c (make_event_array): Use XINT, not XUINT.
12275 There's no need for unsigned here.
12276
12277 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12278 This follows up to the 2011-05-06 change that substituted uintptr_t
12279 for EMACS_INT. This case wasn't caught back then.
12280
12281 Rework Fformat to avoid integer overflow issues.
12282 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12283 now (part of C89). Include <verify.h>.
12284 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12285 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12286 (Fformat): Avoid the prepass trying to compute sizes; it was only
12287 approximate and thus did not catch overflow reliably. Instead, walk
12288 through the format just once, formatting and computing sizes as we go,
12289 checking for integer overflow at every step, and allocating a larger
12290 buffer as needed. Keep track separately whether the format is
12291 multibyte. Keep only the most-recently calculated precision, rather
12292 than them all. Record whether each argument has been converted to
12293 string. Use EMACS_INT, not int, for byte and char and arg counts.
12294 Support field widths and precisions larger than INT_MAX. Avoid
12295 sprintf's undefined behavior with conversion specifications such as %#d
12296 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12297 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12298 formatting out-of-range floating point numbers with int
12299 formats. (Bug#8668)
12300
12301 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12302
12303 * data.c: Avoid integer truncation in expressions involving floats.
12304 * data.c: Include <intprops.h>.
12305 (arith_driver): When there's an integer overflow in an expression
12306 involving floating point, convert the integers to floating point
12307 so that the resulting value does not suffer from catastrophic
12308 integer truncation. For example, on a 64-bit host (* 4
12309 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12310 Do not rely on undefined behavior after integer overflow.
12311
12312 merge count_size_as_multibyte, parse_str_to_multibyte
12313 * character.c, character.h (count_size_as_multibyte):
12314 Rename from parse_str_to_multibyte; all uses changed.
12315 Check for integer overflow.
12316 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12317 since it's now a duplicate of the other. This is more of
12318 a character than a buffer op, so better that it's in character.c.
12319 * fns.c, print.c: Adjust to above changes.
12320
12321 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12322
12323 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12324
12325 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12326
12327 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12328 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12329 (x_clipboard_manager_save): Now static.
12330 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12331
12332 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12333 (crypto_hash_function): Now static.
12334 Fix pointer signedness problems. Avoid unnecessary initializations.
12335
12336 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12337
12338 * termhooks.h (Vselection_alist): Make it terminal-local.
12339
12340 * terminal.c (create_terminal): Initialize it.
12341
12342 * xselect.c: Support for clipboard managers.
12343 (Vselection_alist): Move to termhooks.h as terminal-local var.
12344 (LOCAL_SELECTION): New macro.
12345 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12346 (symbol_to_x_atom): Remove gratuitous arg.
12347 (x_handle_selection_request, lisp_data_to_selection_data)
12348 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12349 (x_own_selection, x_get_local_selection, x_convert_selection):
12350 New arg, specifying work frame. Use terminal-local Vselection_alist.
12351 (some_frame_on_display): Delete unused function.
12352 (Fx_own_selection_internal, Fx_get_selection_internal)
12353 (Fx_disown_selection_internal, Fx_selection_owner_p)
12354 (Fx_selection_exists_p): New optional frame arg.
12355 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12356 (x_handle_selection_clear): Don't treat other terminals with the
12357 same keyboard specially. Use the terminal-local Vselection_alist.
12358 (x_clear_frame_selections): Use Frun_hook_with_args.
12359
12360 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12361
12362 * xterm.h: Add support for those atoms.
12363
12364 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12365
12366 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12367 (converted_selections, conversion_fail_tag): New global variables.
12368 (x_selection_request_lisp_error): Free the above.
12369 (x_get_local_selection): Remove unnecessary code.
12370 (x_reply_selection_request): Args changed; handle arbitrary array
12371 of converted selections stored in converted_selections.
12372 Separate the XChangeProperty and SelectionNotify steps.
12373 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12374 (x_convert_selection): New function.
12375 (x_handle_selection_event): Simplify.
12376 (x_get_foreign_selection): Don't ignore incoming requests while
12377 waiting for an answer; this will fail when we implement
12378 SAVE_TARGETS, and seems unnecessary anyway.
12379 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12380 (Vx_sent_selection_functions): Doc fix.
12381
12382 2011-05-26 Leo Liu <sdl.web@gmail.com>
12383
12384 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12385
12386 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12387
12388 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12389
12390 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12391 for fringe update if it has periodic bitmap.
12392 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12393 and fringe_bitmap_periodic_p.
12394
12395 * fringe.c (get_fringe_bitmap_data): New function.
12396 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12397 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12398 row. Mark glyph row for fringe update if periodicity changed.
12399
12400 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12401 for fringe update unless it has periodic bitmap.
12402
12403 2011-05-25 Kenichi Handa <handa@m17n.org>
12404
12405 * xdisp.c (get_next_display_element): Set correct it->face_id for
12406 a static composition.
12407
12408 2011-05-24 Leo Liu <sdl.web@gmail.com>
12409
12410 * deps.mk (fns.o):
12411 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12412
12413 * fns.c (crypto_hash_function, Fsha1): New function.
12414 (Fmd5): Use crypto_hash_function.
12415 (syms_of_fns): Add Ssha1.
12416
12417 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12418
12419 * gnutls.c: Remove unused macros.
12420 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12421 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12422 Remove macros that are defined and never used.
12423 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12424
12425 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12426
12427 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12428 (Fx_get_selection_internal): Minor cleanup.
12429 (Fx_own_selection_internal): Rename arguments for consistency with
12430 select.el.
12431
12432 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12433
12434 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12435
12436 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12437
12438 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12439
12440 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12441
12442 * dispnew.c (scrolling_window): Don't exclude the case that the
12443 last enabled row in the desired matrix touches the bottom boundary.
12444
12445 2011-05-21 Glenn Morris <rgm@gnu.org>
12446
12447 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12448 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12449 and add some more files.
12450
12451 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12452
12453 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12454 report_file_error introduced by the change from 2011-05-07.
12455
12456 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12457
12458 * systime.h (Time): Define only if emacs is defined.
12459 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12460 where the include path doesn't have X11/X.h by default. See
12461 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12462
12463 2011-05-20 Kenichi Handa <handa@m17n.org>
12464
12465 * composite.c (find_automatic_composition): Fix previous change.
12466
12467 2011-05-20 Glenn Morris <rgm@gnu.org>
12468
12469 * lisp.mk: New file, split from Makefile.in.
12470 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12471 (shortlisp): Remove.
12472 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12473
12474 2011-05-19 Glenn Morris <rgm@gnu.org>
12475
12476 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12477 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12478 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12479 (lisp): Set the order to that of loadup.el.
12480 (shortlisp): Make it a copy of $lisp.
12481 (SOME_MACHINE_LISP): Remove.
12482 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12483 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12484
12485 2011-05-18 Kenichi Handa <handa@m17n.org>
12486
12487 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12488 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12489 (find_automatic_composition): Mostly rewrite for efficiency.
12490
12491 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12492
12493 * makefile.w32-in: Update dependencies.
12494
12495 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12496
12497 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12498 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12499
12500 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12501
12502 Fix some integer overflow issues, such as string length overflow.
12503
12504 * insdel.c (count_size_as_multibyte): Check for string overflow.
12505
12506 * character.c (lisp_string_width): Check for string overflow.
12507 Use EMACS_INT, not int, for string indexes and lengths; in
12508 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12509 the resulting string length overflows an EMACS_INT; instead,
12510 report a string overflow if no precision given. When checking for
12511 precision exhaustion, use a check that cannot possibly have
12512 integer overflow. (Bug#8675)
12513 * character.h (lisp_string_width): Adjust to new signature.
12514
12515 * alloc.c (string_overflow): New function.
12516 (Fmake_string): Use it. This doesn't change behavior, but saves
12517 a few bytes and will simplify future changes.
12518 * character.c (string_escape_byte8): Likewise.
12519 * lisp.h (string_overflow): New decl.
12520
12521 Fixups, following up to the user-interface timestamp change.
12522 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12523 for UI timestamps, instead of unsigned long.
12524 * msdos.c (mouse_get_pos): Likewise.
12525 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12526 * w32gui.h (Time): Define by including "systime.h" rather than by
12527 declaring it ourselves. (Bug#8664)
12528
12529 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12530 * image.c (clear_image_cache): Likewise.
12531
12532 * term.c (term_mouse_position): Don't assume time_t wraparound.
12533
12534 Be more systematic about user-interface timestamps.
12535 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12536 and sometimes 'EMACS_UINT', to represent these timestamps.
12537 This change causes it to use 'Time' uniformly, as that's what X uses.
12538 This makes the code easier to follow, and makes it easier to catch
12539 integer overflow bugs such as Bug#8664.
12540 * frame.c (Fmouse_position, Fmouse_pixel_position):
12541 Use Time, not unsigned long, for user-interface timestamps.
12542 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12543 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12544 * keyboard.h (last_event_timestamp): Likewise.
12545 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12546 * menu.h (xmenu_show): Likewise.
12547 * term.c (term_mouse_position): Likewise.
12548 * termhooks.h (struct input_event.timestamp): Likewise.
12549 (struct terminal.mouse_position_hook): Likewise.
12550 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12551 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12552 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12553 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12554 what it was before.
12555 * menu.h, termhooks.h: Include "systime.h", for Time.
12556
12557 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12558 Don't assume that the difference between two unsigned long values
12559 can fit into an integer. At this point, we know button_down_time
12560 <= event->timestamp, so the difference must be nonnegative, so
12561 there's no need to cast the result if double-click-time is
12562 nonnegative, as it should be; check that it's nonnegative, just in
12563 case. This bug is triggered when events are more than 2**31 ms
12564 apart (about 25 days). (Bug#8664)
12565
12566 * xselect.c (last_event_timestamp): Remove duplicate decl.
12567 (x_own_selection): Remove needless cast to unsigned long.
12568
12569 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12570 that always fit in int. Use a sentinel instead of a counter, to
12571 avoid a temp and to allay GCC's concerns about possible int overflow.
12572 * frame.h (struct frame): Use int for menu_bar_items_used
12573 instead of EMACS_INT, since it always fits in int.
12574
12575 * menu.c (grow_menu_items): Check for int overflow.
12576
12577 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12578
12579 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12580 Before, the code was not consistent. These values cannot exceed
12581 2**31 - 1 so there's no need to make them unsigned.
12582 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12583 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12584 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12585 as modifiers.
12586 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12587
12588 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12589 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12590 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12591 presumably because the widths might not match.
12592
12593 * window.c (size_window): Avoid needless test at loop start.
12594
12595 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12596
12597 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12598
12599 2011-05-12 Drew Adams <drew.adams@oracle.com>
12600
12601 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12602
12603 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12604
12605 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12606 `width' to `bar_area_x' and `bar_area_width', respectively.
12607 (x_scroll_run): Take account of fringe background extension.
12608
12609 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12610 Rename local vars `left' and `width' to `bar_area_x' and
12611 `bar_area_width', respectively.
12612 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12613 background extension.
12614
12615 2011-05-10 Jim Meyering <meyering@redhat.com>
12616
12617 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12618
12619 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12620
12621 * image.c (Finit_image_library): Return t for built-in image types,
12622 like pbm and xbm. (Bug#8640)
12623
12624 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12625
12626 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12627
12628 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12629
12630 * w32console.c (Fset_screen_color): Doc fix.
12631 (Fget_screen_color): New function.
12632 (syms_of_ntterm): Defsubr it.
12633
12634 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12635 unlink the temporary file if Fcall_process didn't create it in the
12636 first place.
12637 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12638 child process will be redirected to a file specified with `:file'.
12639 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12640 cue to call_process_cleanup not to close that handle.
12641
12642 2011-05-07 Ben Key <bkey76@gmail.com>
12643
12644 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12645 one of two shell specific rules, either bootstrap-temacs-CMD or
12646 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12647 to the previous implementation of the bootstrap-temacs rule.
12648 The bootstrap-temacs-CMD rule is similar to the previous
12649 implementation of the bootstrap-temacs rule except that it
12650 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12651 variable.
12652
12653 These changes, along with some changes to nt/configure.bat,
12654 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12655 earlier fix to add support for --cflags and --ldflags options
12656 that include quotes so that it works whether make uses cmd or
12657 sh as the shell.
12658
12659 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12660
12661 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12662 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12663 is a constant.
12664 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12665 a string. Handle both cases.
12666 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12667 (Fdbus_register_method): Use Qinvalid_function.
12668
12669 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12670
12671 * makefile.w32-in: Update dependencies.
12672 (LISP_H): Add inttypes.h and stdin.h.
12673 (PROCESS_H): Add unistd.h.
12674
12675 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12676
12677 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12678 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12679
12680 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12681
12682 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12683
12684 * term.c (vfatal): Remove stray call to va_end.
12685 It's not needed and the C Standard doesn't allow it here anyway.
12686
12687 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12688 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12689
12690 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12691 bytes.
12692
12693 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12694
12695 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12696
12697 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12698
12699 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12700
12701 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12702
12703 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12704 * charset.c (Fdefine_charset_internal): Don't initialize
12705 charset.code_space[15]. The value was garbage, on hosts with
12706 32-bit int (Bug#8600).
12707
12708 * lread.c (read_integer): Be more consistent with string-to-number.
12709 Use string_to_number to do the actual conversion; this avoids
12710 rounding errors and fixes some other screwups. Without this fix,
12711 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12712 (digit_to_number): Move earlier, for benefit of read_integer.
12713 Return -1 if the digit is out of range for the base, -2 if it is
12714 not a digit in any supported base. (Bug#8602)
12715
12716 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12717
12718 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12719 to match comment at start of function. This also removes a
12720 GCC warning about overflow in a 32+64-bit port.
12721
12722 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12723
12724 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12725 Reported by Stefan Monnier in
12726 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12727 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12728 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12729
12730 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12731 (EMACS_UINTPTR): Likewise, with uintptr_t.
12732
12733 * lisp.h: Prefer 64-bit EMACS_INT if available.
12734 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12735 on 32-bit hosts that have 64-bit int, so that they can access
12736 large files.
12737 However, temporarily disable this change unless the temporary
12738 symbol WIDE_EMACS_INT is defined.
12739
12740 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12741
12742 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12743 This removes an assumption that EMACS_INT and long are the same
12744 width as pointers. The assumption is true for Emacs porting targets
12745 now, but we want to make other targets possible.
12746 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12747 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12748 In the rest of the code, change types of integers that hold casted
12749 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12750 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12751 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12752 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12753 No need to cast type when ORing.
12754 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12755 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12756 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12757 assume EMACS_INT is the same width as char *.
12758 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12759 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12760 Remove no-longer-needed casts.
12761 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12762 (xg_tool_bar_help_callback, xg_make_tool_item):
12763 Use EMACS_INTPTR to hold an integer
12764 that will be cast to void *; this can avoid a GCC warning
12765 if EMACS_INT is not the same width as void *.
12766 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12767 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12768 (current_message_1, set_message_1):
12769 Use a local to convert to proper width without a cast.
12770 * xmenu.c (dialog_selection_callback): Likewise.
12771
12772 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12773 Also, don't assume VALBITS / RAND_BITS is less than 5,
12774 and don't rely on undefined behavior when shifting a 1 left into
12775 the sign bit.
12776 * lisp.h (get_random): Change signature to match.
12777
12778 * lread.c (hash_string): Use size_t, not int, for hash computation.
12779 Normally we prefer signed values; but hashing is special, because
12780 it's better to use unsigned division on hash table sizes so that
12781 the remainder is nonnegative. Also, size_t is the natural width
12782 for hashing into memory. The previous code used 'int', which doesn't
12783 retain enough info to hash well into very large tables.
12784 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12785
12786 * dbusbind.c: Don't possibly lose pointer info when converting.
12787 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12788 Use XPNTR rather than XHASH, so that the high-order bits of
12789 the pointer aren't lost when converting through void *.
12790
12791 * eval.c (Fautoload): Don't double-shift a pointer.
12792
12793 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12794
12795 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12796
12797 * gnutls.c (DEF_GNUTLS_FN):
12798 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12799
12800 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12801
12802 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12803 marker. (Bug#8610)
12804
12805 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12806
12807 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12808 New version that can reserve upto 2GB of heap space.
12809
12810 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12811
12812 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12813
12814 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12815
12816 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12817 `gnutls_certificate_set_x509_key_file'.
12818
12819 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12820
12821 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12822 Update dependencies.
12823
12824 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12825
12826 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12827 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12828 Remove unused parameter `fildes'.
12829 * process.c (read_process_output, send_process): Don't pass it.
12830
12831 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12832
12833 Fix previous change: the library cache is defined in w32.c.
12834 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12835 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12836
12837 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12838
12839 Implement dynamic loading of GnuTLS on Windows.
12840
12841 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12842 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12843 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12844 Declare.
12845
12846 * gnutls.c (Qgnutls_dll): Define.
12847 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12848 (gnutls_*): Declare function pointers.
12849 (init_gnutls_functions): New function to initialize function pointers.
12850 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12851 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12852 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12853 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12854 (emacs_gnutls_write, emacs_gnutls_read)
12855 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12856 (Fgnutls_available_p): New function.
12857 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

12859 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12860
12861 * image.c: Include w32.h.
12862 (Vimage_type_cache): Delete.
12863 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12864 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12865 (w32_delayed_load): Move to w32.c.
12866
12867 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12868
12869 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12870 (w32_delayed_load): Move from image.c. When loading a library, record
12871 its filename in the :loaded-from property of the library id.
12872 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12873 Initialize and staticpro them.
12874 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12875
12876 * process.c: Include lisp.h before w32.h, not after.
12877 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12878 instead of gnutls_record_check_pending.
12879
12880 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12881
12882 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12883
12884 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12885 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12886 as passed in.
12887
12888 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12889
12890 * xterm.c (x_set_frame_alpha): Do not set property on anything
12891 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12892
12893 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12894
12895 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12896
12897 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12898
12899 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12900 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
12901 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)
12902 (gnutls_global_initialized, Qgnutls_bootprop_priority)
12903 (Qgnutls_bootprop_trustfiles, Qgnutls_bootprop_keyfiles)
12904 (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel)
12905 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
12906 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
12907 (Qgnutls_bootprop_callbacks_verify): Make static.
12908
12909 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
12910
12911 * callproc.c: Indentation fixup.
12912
12913 * sysdep.c (wait_for_termination_1): Make static.
12914 (wait_for_termination, interruptible_wait_for_termination):
12915 Move after wait_for_termination_1.
12916
12917 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12918
12919 * sysdep.c (interruptible_wait_for_termination): New function
12920 which is like wait_for_termination, but allows keyboard
12921 interruptions.
12922
12923 * callproc.c (Fcall_process): Add (:file "file") as an option for
12924 the STDOUT buffer.
12925 (Fcall_process_region): Ditto.
12926
12927 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12928
12929 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12930 rather than `XVECTOR (FOO)->size'.
12931
12932 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12933 inttypes.h, as a gnulib replacement is used if it not available in
12934 system headers.
12935

12938 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12939 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12940 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12941
12942 * coding.c (coding_alloc_by_realloc): Error out if destination
12943 will grow beyond MOST_POSITIVE_FIXNUM.
12944 (decode_coding_emacs_mule): Abort if there isn't enough place in
12945 charbuf for the composition carryover bytes. Reserve an extra
12946 space for up to 2 characters produced in a loop.
12947 (decode_coding_iso_2022): Abort if there isn't enough place in
12948 charbuf for the composition carryover bytes.
12949
12950 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12951
12952 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12953 aborting when %lld or %lll format is passed.
12954 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12955 %llo or %llx format is passed. (Bug#8545)
12956
12957 * window.c (window_scroll_line_based): Use a marker instead of
12958 simple variables to record original value of point. (Bug#7952)
12959
12960 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12961 produced by %s or %c overflows available buffer space. (Bug#8545)
12962
12963 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12964
12965 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12966 (SIZE_MAX): Move defn after all includes, as they might #define it.
12967
12968 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12969
12970 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12971
12972 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12973
12974 * keyboard.c (Qdelayed_warnings_hook): Define.
12975 (command_loop_1): Run `delayed-warnings-hook'
12976 if Vdelayed_warnings_list is non-nil.
12977 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12978 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12979
12980 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12981
12982 * doprnt.c (doprnt): Don't return value smaller than the buffer
12983 size if the message was truncated. (Bug#8545).
12984
12985 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12986
12987 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12988 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12989
12990 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12991
12992 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12993
12994 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12995
12996 * makefile.w32-in: Update dependencies.
12997
12998 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12999
13000 Improve `doprnt' and its usage. (Bug#8545)
13001 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
13002 `format_end'. Remove support for %l as a conversion specifier.
13003 Don't use xrealloc. Improve diagnostics when the %l size modifier
13004 is used. Update the commentary.
13005
13006 * eval.c (verror): Simplify calculation of size_t.
13007
13008 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
13009 messages.
13010
13011 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
13012
13013 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
13014 change.
13015
13016 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
13017
13018 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
13019 This makes this file independent of the recent pseudovector change.
13020
13021 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
13022
13023 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
13024
13025 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
13026 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
13027 Remove unused local.
13028 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
13029
13030 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
13031 GCC 4.6.0 optimizes based on type-based alias analysis.
13032 For example, if b is of type struct buffer * and v of type struct
13033 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
13034 != &v->size, and therefore "v->size = 1; b->size = 2; return
13035 v->size;" must therefore return 1. This assumption is incorrect
13036 for Emacs, since it type-puns struct Lisp_Vector * with many other
13037 types. To fix this problem, this patch adds a new type struct
13038 vectorlike_header that documents the constraints on layout of vectors
13039 and pseudovectors, and helps optimizing compilers not get fooled
13040 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
13041 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
13042 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
13043 the size member.
13044 (XSETPVECTYPE): Rewrite in terms of new macro.
13045 (XSETPVECTYPESIZE): New macro, specifying both type and size.
13046 This is a bit clearer, and further avoids the possibility of
13047 undesirable aliasing.
13048 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
13049 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
13050 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
13051 since Lisp_Subr is a special case (no "next" field).
13052 (ASIZE): Now uses header.size rather than size.
13053 All previous uses of XVECTOR (foo)->size replaced to use this macro,
13054 to avoid the hassle of writing XVECTOR (foo)->header.size.
13055 (struct vectorlike_header): New type.
13056 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
13057 object, to help avoid aliasing.
13058 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
13059 (SUBRP): Likewise, since Lisp_Subr is a special case.
13060 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
13061 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
13062 (struct Lisp_Hash_Table): Combine first two members into a single
13063 struct vectorlike_header member. All uses of "size" and "next" members
13064 changed to be "header.size" and "header.next".
13065 * buffer.h (struct buffer): Likewise.
13066 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
13067 * frame.h (struct frame): Likewise.
13068 * process.h (struct Lisp_Process): Likewise.
13069 * termhooks.h (struct terminal): Likewise.
13070 * window.c (struct save_window_data, struct saved_window): Likewise.
13071 * window.h (struct window): Likewise.
13072 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
13073 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
13074 * buffer.c (init_buffer_once): Likewise.
13075 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
13076 special case.
13077 * process.c (Fformat_network_address): Use local var for size,
13078 for brevity.
13079
13080 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
13081
13082 Make the Lisp reader and string-to-float more consistent (Bug#8525)
13083 * data.c (atof): Remove decl; no longer used or needed.
13084 (digit_to_number): Move to lread.c.
13085 (Fstring_to_number): Use new string_to_number function, to be
13086 consistent with how the Lisp reader treats infinities and NaNs.
13087 Do not assume that floating-point numbers represent EMACS_INT
13088 without losing information; this is not true on most 64-bit hosts.
13089 Avoid double-rounding errors, by insisting on integers when
13090 parsing non-base-10 numbers, as the documentation specifies.
13091 * lisp.h (string_to_number): New decl, replacing ...
13092 (isfloat_string): Remove.
13093 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
13094 (read1): Do not accept +. and -. as integers; this
13095 appears to have been a coding error. Similarly, do not accept
13096 strings like +-1e0 as floating point numbers. Do not report
13097 overflow for integer overflows unless the base is not 10 which
13098 means we have no simple and reliable way to continue.
13099 Break out the floating-point parsing into a new
13100 function string_to_number, so that Fstring_to_number parses
13101 floating point numbers consistently with the Lisp reader.
13102 (digit_to_number): Move here from data.c. Make it static inline.
13103 (E_CHAR, EXP_INT): Remove, replacing with ...
13104 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
13105 (string_to_number): New function, replacing isfloat_string.
13106 This function checks for valid syntax and produces the resulting
13107 Lisp float number too. Rework it so that string-to-number
13108 no longer mishandles examples like "1.0e+". Use strtoumax,
13109 so that overflow for non-base-10 numbers is reported only when
13110 there's no portable and simple way to convert to floating point.
13111
13112 * textprop.c (set_text_properties_1): Rewrite for clarity,
13113 and to avoid GCC warning about integer overflow.
13114
13115 * intervals.h (struct interval): Use EMACS_INT for members
13116 where EMACS_UINT might cause problems. See
13117 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
13118 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
13119 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
13120 All uses changed.
13121 (offset_intervals): Tell GCC not to worry about length overflow
13122 when negating a negative length.
13123
13124 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
13125 (overrun_check_free): Likewise.
13126
13127 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
13128 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
13129 word size.
13130
13131 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13132 (gnutls_make_error): Rename local to avoid shadowing.
13133 (gnutls_emacs_global_deinit): ifdef out; not used.
13134 (Fgnutls_boot): Use const for pointer to readonly storage.
13135 Comment out unused local. Fix pointer signedness problems.
13136
13137 * lread.c (openp): Don't stuff size_t into an 'int'.
13138 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
13139 about possible signed overflow.
13140
13141 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13142 (GDK_KEY_g): Don't define if already defined.
13143 (xg_prepare_tooltip): Avoid pointer signedness problem.
13144 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
13145
13146 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
13147 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
13148
13149 * xfns.c (Fx_window_property): Simplify a bit,
13150 to make a bit faster and to avoid GCC 4.6.0 warning.
13151 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
13152
13153 * fns.c (internal_equal): Don't assume size_t fits in int.
13154
13155 * alloc.c (compact_small_strings): Tighten assertion a little.
13156
13157 Replace pEd with more-general pI, and fix some printf arg casts.
13158 * lisp.h (pI): New macro, generalizing old pEd macro to other
13159 conversion specifiers. For example, use "...%"pI"d..." rather
13160 than "...%"pEd"...".
13161 (pEd): Remove. All uses replaced with similar uses of pI.
13162 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
13163 * alloc.c (check_pure_size): Don't overflow by converting size to int.
13164 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
13165 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
13166 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
13167 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
13168 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
13169 64-bit hosts.
13170 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
13171 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
13172 * print.c (safe_debug_print, print_object): Likewise.
13173 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
13174 to int.
13175 Use pI instead of if-then-else-abort. Use %p to avoid casts,
13176 avoiding the 0 flag, which is not portable.
13177 * process.c (Fmake_network_process): Use pI to avoid cast.
13178 * region-cache.c (pp_cache): Likewise.
13179 * xdisp.c (decode_mode_spec): Likewise.
13180 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
13181 behavior on 64-bit hosts with printf arg.
13182 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
13183 (x_stop_queuing_selection_requests): Likewise.
13184 (x_get_window_property): Don't truncate byte count to an 'int'
13185 when tracing.
13186
13187 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
13188 here, since it parses constructs like leading '-' and spaces,
13189 which are not wanted; and it overflows with large numbers.
13190 Instead, simply match F[0-9]+, which is what is wanted anyway.
13191
13192 * alloc.c: Remove unportable assumptions about struct layout.
13193 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
13194 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
13195 (allocate_vectorlike, make_pure_vector): Use the new macros,
13196 plus offsetof, to remove unportable assumptions about struct layout.
13197 These assumptions hold on all porting targets that I know of, but
13198 they are not guaranteed, they're easy to remove, and removing them
13199 makes further changes easier.
13200
13201 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
13202 This doesn't fix a bug but makes the code clearer.
13203 (string_overrun_cookie): Now const. Use initializers that
13204 don't formally overflow signed char, to avoid warnings.
13205 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
13206 can cause Emacs to crash when string overrun checking is enabled.
13207 (allocate_buffer): Don't assume sizeof (struct buffer) is a
13208 multiple of sizeof (EMACS_INT); it need not be, if
13209 alignof(EMACS_INT) < sizeof (EMACS_INT).
13210 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
13211
13212 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
13213
13214 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
13215
13216 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
13217
13218 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
13219 supposed to be handshaking. (Bug#8556)
13220 Reported by Paul Eggert <eggert@cs.ucla.edu>.
13221
13222 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
13223
13224 * lisp.h (Qdebug): List symbol.
13225 * eval.c (Qdebug): Restore global linkage.
13226 * keyboard.c (debug-on-event): New variable.
13227 (handle_user_signal): Break into debugger when debug-on-event
13228 matches the current signal symbol.
13229
13230 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
13231
13232 * alloc.c (check_sblock, check_string_bytes)
13233 (check_string_free_list): Convert to standard C.
13234
13235 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
13236
13237 * w32.c (emacs_gnutls_push): Fix typo.
13238
13239 2011-04-25 Eli Zaretskii <eliz@gnu.org>
13240
13241 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
13242 "cast to pointer from integer of different size".
13243
13244 Improve doprnt and its use in verror. (Bug#8545)
13245 * doprnt.c (doprnt): Document the set of format control sequences
13246 supported by the function. Use SAFE_ALLOCA instead of always
13247 using `alloca'.
13248
13249 * eval.c (verror): Don't limit the buffer size at size_max-1, that
13250 is one byte too soon. Don't use xrealloc; instead xfree and
13251 xmalloc anew.
13252
13253 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
13254
13255 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
13256 callbacks stage.
13257
13258 * gnutls.c: Renamed global_initialized to
13259 gnutls_global_initialized. Added internals for the
13260 :verify-hostname-error, :verify-error, and :verify-flags
13261 parameters of `gnutls-boot' and documented those parameters in the
13262 docstring. Start callback support.
13263 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
13264 unless a fatal error occurred. Call gnutls_alert_send_appropriate
13265 on error. Return error code.
13266 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
13267 (emacs_gnutls_read): Likewise.
13268 (Fgnutls_boot): Return handshake error code.
13269 (emacs_gnutls_handle_error): New function.
13270 (wsaerror_to_errno): Likewise.
13271
13272 * w32.h (emacs_gnutls_pull): Add prototype.
13273 (emacs_gnutls_push): Likewise.
13274
13275 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
13276 (emacs_gnutls_push): Likewise.
13277
13278 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
13279
13280 * process.c (wait_reading_process_output): Check if GnuTLS
13281 buffered some data internally if no FDs are set for TLS
13282 connections.
13283
13284 * makefile.w32-in (OBJ2): Add gnutls.$(O).
13285 (LIBS): Link to USER_LIBS.
13286 ($(BLD)/gnutls.$(0)): New target.
13287
13288 2011-04-24 Eli Zaretskii <eliz@gnu.org>
13289
13290 * xdisp.c (handle_single_display_spec): Rename the
13291 display_replaced_before_p argument into display_replaced_p, to
13292 make it consistent with the commentary. Fix typos in the
13293 commentary.
13294
13295 * textprop.c (syms_of_textprop): Remove dead code.
13296 (copy_text_properties): Delete obsolete commentary about an
13297 interface that was deleted long ago. Fix typos in the description
13298 of arguments.
13299
13300 * msdos.c (XMenuActivate, XMenuAddSelection): Adjust argument list
13301 to changes in oldXMenu/XMenu.h from 2011-04-16.
13302 <menu_help_message, prev_menu_help_message>: Constify.
13303 (IT_menu_make_room): menu->help_text is now `const char **';
13304 adjust.
13305
13306 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
13307 to changes in oldXMenu/XMenu.h from 2011-04-16.
13308 (struct XMenu): Declare `help_text' `const char **'.
13309
13310 * xfaces.c <Qunspecified>: Make extern again.
13311
13312 * syntax.c: Include sys/types.h before including regex.h, as
13313 required by POSIX.
13314
13315 * doc.c (get_doc_string): Improve the format passed to `error'.
13316
13317 * doprnt.c (doprnt): Improve commentary.
13318
13319 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
13320
13321 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
13322 them with etags.
13323

13570 ns_descriptor_to_entity that were caused by using free to

13573 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
13574 --enable-checking=xmallocoverrun). xfree is now used to
13575 deallocate these memory blocks.

14104 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
14105 This also lets GCC 4.6.0 generate slightly better loop code.
14106
14107 * callint.c (Fcall_interactively): <, not <=, for optimization.
14108 (Fcall_interactively): Count the number of arguments produced,
14109 not the number of arguments given. This is simpler and lets GCC
14110 4.6.0 generate slightly better code.
14111
14112 * ftfont.c: Distingish more carefully between FcChar8 and char.
14113 The previous code passed unsigned char * to a functions like
14114 strlen and xstrcasecmp that expect char *, which does not
14115 conform to the C standard.
14116 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
14117 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
14118 char * when the C standard requires it.
14119
14120 * keyboard.c (read_char): Remove unused var.
14121
14122 * eval.c: Port to Windows vsnprintf (Bug#8435).
14123 Include <limits.h>.
14124 (SIZE_MAX): Define if the headers do not.
14125 (verror): Do not give up if vsnprintf returns a negative count.
14126 Instead, grow the buffer. This ports to Windows vsnprintf, which
14127 does not conform to C99. Problem reported by Eli Zaretskii.
14128 Also, simplify the allocation scheme, by avoiding the need for
14129 calling realloc, and removing the ALLOCATED variable.
14130
14131 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
14132
14133 Remove invocations of doprnt, as Emacs now uses vsnprintf.
14134 But keep the doprint source code for now, as we might revamp it
14135 and use it again (Bug#8435).
14136 * lisp.h (doprnt): Remove.
14137 * Makefile.in (base_obj): Remove doprnt.o.
14138 * deps.mk (doprnt.o): Remove.
14139
14140 error: Print 32- and 64-bit integers portably (Bug#8435).
14141 Without this change, on typical 64-bit hosts error ("...%d...", N)
14142 was used to print both 32- and 64-bit integers N, which relied on
14143 undefined behavior.
14144 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
14145 * lisp.h (error, verror): Mark as printf-like functions.
14146 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
14147 Report overflow in size calculations when allocating printf buffer.
14148 Do not truncate output string at its first null byte.
14149 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
14150 Truncate the output at a character boundary, since vsnprintf does not
14151 do that.
14152 * charset.c (check_iso_charset_parameter): Convert internal
14153 character to string before calling 'error', since %c now has the
14154 printf meaning.
14155 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
14156 overflow when computing char to be passed to 'error'. Do not
14157 pass Lisp_Object to 'error'; pass the integer instead.
14158 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
14159 formatted with plain %d.
14160
14161 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
14162
14163 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
14164
14165 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
14166
14167 * xterm.c (x_catch_errors): Remove duplicate declaration.
14168
14169 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
14170
14171 * xdisp.c, lisp.h (message_nolog): Remove; unused.
14172
14173 2011-04-10 Jim Meyering <meyering@redhat.com>
14174
14175 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
14176 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
14177 return ssize_t not "int", and use size_t as the buffer length.
14178 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
14179 * gnutls.h: Update declarations.
14180 * process.c (read_process_output): Use ssize_t, to match.
14181 (send_process): Likewise.
14182
14183 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14184
14185 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
14186
14187 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14188
14189 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
14190 Use unsigned char, to match FcChar8 type definition.
14191
14192 * xterm.c (handle_one_xevent):
14193 * xmenu.c (create_and_show_popup_menu):
14194 * xselect.c (x_decline_selection_request)
14195 (x_reply_selection_request): Avoid type-punned deref of X events.
14196
14197 2011-04-09 Eli Zaretskii <eliz@gnu.org>
14198
14199 Fix some uses of `int' instead of EMACS_INT.
14200 * search.c (string_match_1, fast_string_match)
14201 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
14202 (scan_buffer, find_next_newline_no_quit)
14203 (find_before_next_newline, search_command, Freplace_match)
14204 (Fmatch_data): Make some `int' variables be EMACS_INT.
14205
14206 * xdisp.c (display_count_lines): 3rd argument and return value now
14207 EMACS_INT. All callers changed.
14208 (pint2hrstr): Last argument is now EMACS_INT.
14209
14210 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
14211 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
14212 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
14213 (decode_coding_utf_16, decode_coding_emacs_mule)
14214 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
14215 (decode_coding_ccl, decode_coding_charset)
14216 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
14217 (decode_coding_iso_2022, decode_coding_emacs_mule)
14218 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
14219 <char_offset, last_offset>: Declare EMACS_INT.
14220 (encode_coding_utf_8, encode_coding_utf_16)
14221 (encode_coding_emacs_mule, encode_invocation_designation)
14222 (encode_designation_at_bol, encode_coding_iso_2022)
14223 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
14224 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
14225 Declare EMACS_INT.
14226 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
14227 (encode_invocation_designation): Last argument P_NCHARS is now
14228 EMACS_INT.
14229 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
14230 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
14231
14232 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
14233 All users changed.
14234
14235 * ccl.c (Fccl_execute_on_string): Declare some variables
14236 EMACS_INT.
14237
14238 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
14239
14240 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
14241
14242 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
14243
14244 * process.c (Fformat_network_address): Doc fix.
14245
14246 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
14247
14248 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
14249
14250 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
14251
14252 * keyboard.c (read_char): Call Lisp function help-form-show,
14253 instead of using internal_with_output_to_temp_buffer.
14254 (Qhelp_form_show): New var.
14255 (syms_of_keyboard): Use DEFSYM macro.
14256
14257 * print.c (internal_with_output_to_temp_buffer): Function deleted.
14258
14259 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
14260
14261 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
14262
14263 * process.c (Flist_processes): Remove to Lisp.
14264 (list_processes_1): Delete.
14265
14266 2011-04-06 Eli Zaretskii <eliz@gnu.org>
14267
14268 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
14269
14270 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
14271
14272 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
14273
14274 Fix more problems found by GCC 4.6.0's static checks.
14275
14276 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
14277
14278 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
14279
14280 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
14281
14282 * xdisp.c (vmessage): Mark as a printf-like function.
14283
14284 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
14285
14286 * sound.c (sound_warning): Don't crash if arg contains a printf format.
14287
14288 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
14289 printf-like functions.
14290 (tiff_load): Add casts to remove these marks before passing them
14291 to system-supplied API.
14292
14293 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14294
14295 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14296 This avoids several warnings with gcc -Wstrict-overflow.
14297 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14298 directly, rather than having caller test rule sign. This avoids
14299 some unnecessary tests.
14300 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14301 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14302 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14303
14304 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14305 (xfont_open): Avoid unnecessary tests.
14306
14307 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14308
14309 * composite.h, composite.c (composition_gstring_put_cache):
14310 Use EMACS_INT, not int, for length.
14311
14312 * composite.h (COMPOSITION_DECODE_REFS): New macro,
14313 breaking out part of COMPOSITION_DECODE_RULE.
14314 (COMPOSITION_DECODE_RULE): Use it.
14315 * composite.c (get_composition_id): Remove unused local vars,
14316 by using the new macro.
14317
14318 * textprop.c (set_text_properties_1): Change while to do-while,
14319 since the condition is always true at first.
14320
14321 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14322 (interval_deletion_adjustment): Return unsigned value.
14323 All uses changed.
14324
14325 * process.c (list_processes_1, create_pty, read_process_output):
14326 (exec_sentinel): Remove vars that were set but not used.
14327 (create_pty): Remove unnecessary "volatile"s.
14328 (Fnetwork_interface_info): Avoid possibility of int overflow.
14329 (read_process_output): Do adaptive read buffering even if carryover.
14330 (read_process_output): Simplify nbytes computation if buffered.
14331
14332 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
14333
14334 * syntax.c (scan_words): Remove var that was set but not used.
14335 (update_syntax_table): Use unsigned instead of int.
14336
14337 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
14338 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
14339 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
14340
14341 * print.c (print_error_message): Avoid int overflow.
14342
14343 * font.c (font_list_entities): Redo for clarity,
14344 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14345
14346 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14347 (font_score): Avoid potential overflow in diff calculation.
14348
14349 * fns.c (substring_both): Remove var that is set but not used.
14350 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14351
14352 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14353
14354 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14355 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14356 can always succeed if overflow has undefined behavior.
14357
14358 * search.c (boyer_moore, wordify): Remove vars set but not used.
14359 (wordify): Omit three unnecessary tests.
14360
14361 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
14362 All callers changed. This avoids the need for an unused var.
14363
14364 * casefiddle.c (casify_region): Remove var that is set but not used.
14365
14366 * dired.c (file_name_completion): Remove var that is set but not used.
14367
14368 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
14369
14370 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
14371 (Finsert_file_contents): Remove unnecessary code checking fd.
14372
14373 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14374 Check for integer overflow on size calculations.
14375
14376 * buffer.c (Fprevious_overlay_change): Remove var that is set
14377 but not used.
14378
14379 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14380 Remove vars that are set but not used.
14381 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
14382 (timer_check_2): Mark vars as initialized.
14383
14384 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
14385
14386 * image.c (lookup_image): Remove var that is set but not used.
14387 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
14388
14389 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14390 that are set but not used.
14391
14392 * xfns.c (make_invisible_cursor): Don't return garbage
14393 if XCreateBitmapFromData fails (Bug#8410).
14394
14395 * xselect.c (x_get_local_selection, x_handle_property_notify):
14396 Remove vars that are set but not used.
14397
14398 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
14399 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
14400
14401 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
14402 Remove var that is set but not used.
14403 (scroll_bar_windows_size): Now size_t, not int.
14404 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
14405 Check for overflow.
14406
14407 * xfaces.c (realize_named_face): Remove vars that are set but not used.
14408 (map_tty_color) [!defined MSDOS]: Likewise.
14409
14410 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14411
14412 * coding.c: Remove vars that are set but not used.
14413 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14414 All callers changed.
14415 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
14416 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):

14418
14419 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
14420 that is set but not used.
14421
14422 * print.c (print_object): Remove var that is set but not used.
14423
14424 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14425 The gnulib version avoids calling malloc in the usual case,
14426 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14427 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14428 * filelock.c (current_lock_owner): Likewise.
14429 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14430 * sysdep.c: Include allocator.h, careadlinkat.h.
14431 (emacs_no_realloc_allocator): New static constant.

14437
14438 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14439 first non-nil return value).
14440
14441 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
14442
14443 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
14444 if not defined (Bug#8403).
14445
14446 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14447
14448 * xdisp.c (display_count_lines): Remove parameter `start',
14449 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

14451 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
14452 (fill_stretch_glyph_string): Remove parameters `row' and `area',
14453 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
14454 and thereabouts. All callers changed.
14455 (get_per_char_metric): Remove parameter `f', unused since
14456 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
14457
14458 2011-04-02 Jim Meyering <meyering@redhat.com>
14459
14460 do not dereference NULL upon failed strdup
14461 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
14462 (ns_get_family): Likewise.
14463
14464 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14465
14466 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
14467
14468 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
14469
14470 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
14471 later (Bug#8403).

14494
14495 * image.c (parse_image_spec): Use Ffunctionp.

14497 * fns.c (concat, mapcar1): Accept byte-code-functions.
14498
14499 * eval.c (Fsetq): Handle lexical vars.
14500 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.

14504 (Feval): New `lexical' arg.
14505 (eval_sub): New function extracted from Feval. Use it almost
14506 everywhere where Feval was used. Look up vars in lexical env.
14507 Handle closures.
14508 (Ffunctionp): Move from subr.el.
14509 (Ffuncall): Handle closures.
14510 (apply_lambda): Remove `eval_flags'.
14511 (funcall_lambda): Handle closures and new byte-code-functions.
14512 (Fspecial_variable_p): New function.
14513 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14514 but without exporting it to Lisp.
14515
14516 * doc.c (Fdocumentation, store_function_docstring):
14517 * data.c (Finteractive_form): Handle closures.
14518
14519 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14520 interactive spec.
14521
14522 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14523 New byte-codes.
14524 (exec_byte_code): New function extracted from Fbyte_code to handle new
14525 calling convention for byte-code-functions. Add new byte-codes.
14526
14527 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14528
14529 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14530
14531 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14532
14533 * xdisp.c (redisplay_internal): Fix prototype.
14534
14535 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14536
14537 * xdisp.c (SCROLL_LIMIT): New macro.
14538 (try_scrolling): Use it when setting scroll_limit.
14539 Limit scrolling to 100 screen lines.
14540 (redisplay_window): Even when falling back on "recentering",
14541 position point in the window according to scroll-conservatively,
14542 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14543
14544 (try_scrolling): When point is above the window, allow searching
14545 as far as scroll_max, or one screenful, to compute vertical
14546 distance from PT to the scroll margin position. This prevents
14547 try_scrolling from unnecessarily failing when
14548 scroll-conservatively is set to a value slightly larger than the
14549 window height. Clean up the case of PT below the margin at bottom
14550 of window: scroll_max can no longer be INT_MAX. When aggressive
14551 scrolling is in use, don't let point enter the opposite scroll
14552 margin as result of the scroll.
14553 (syms_of_xdisp) <scroll-conservatively>: Document the
14554 threshold of 100 lines for never-recentering scrolling.
14555
14556 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14557
14558 * dispextern.h (move_it_by_lines):
14559 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
14560 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.

14562 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14563 (redisplay_internal): Remove parameter `preserve_echo_area',
14564 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14565
14566 * indent.c (Fvertical_motion):
14567 * window.c (window_scroll_pixel_based, Frecenter):
14568 Don't pass `need_y_p' to `move_it_by_lines'.
14569
14570 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14571
14572 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14573 steal a few bits to be more compact.
14574 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14575 Remove unneeded casts.
14576
14577 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14578
14579 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14580
14581 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14582 binding" message (bug#7967).
14583
14584 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14585
14586 Fix more problems found by GCC 4.6.0's static checks.
14587
14588 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14589 Remove unused local var.
14590
14591 * editfns.c (Fmessage_box): Remove unused local var.
14592
14593 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14594 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14595 Omit unused local vars.
14596 * window.c (shrink_windows): Omit unused local var.
14597 * menu.c (digest_single_submenu): Omit unused local var.
14598 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14599 Omit unused local var.
14600
14601 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14602 Don't assume string length fits in int.
14603 (keyremap_step, read_key_sequence): Use size_t for sizes.
14604 (read_key_sequence): Don't check last_real_key_start redundantly.
14605
14606 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14607 instead of alloca (Bug#8344).
14608
14609 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14610 (Fbacktrace_frame): Don't assume nframes fits in int.
14611
14612 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14613
14614 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14615 concerns.
14616
14617 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14618
14619 * cm.c (calccost): Turn while-do into do-while, for clarity.
14620
14621 * keyboard.c (syms_of_keyboard): Use the same style as later
14622 in this function when indexing through an array. This also
14623 works around GCC bug 48267.
14624
14625 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14626
14627 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14628
14629 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14630 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14631
14632 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14633 This avoids undefined behavior on integer overflow, and is a bit
14634 more convenient anyway since it is compared to a size_t variable.
14635
14636 Variadic C functions now count arguments with size_t, not int.
14637 This avoids an unnecessary limitation on 64-bit machines, which
14638 caused (substring ...) to crash on large vectors (Bug#8344).
14639 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14640 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14641 All variadic functions and their callers changed accordingly.
14642 (struct gcpro.nvars): Now size_t, not int. All uses changed.
14643 * data.c (arith_driver, float_arith_driver): Likewise.
14644 * editfns.c (general_insert_function): Likewise.
14645 * eval.c (struct backtrace.nargs, interactive_p)
14646 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14647 (funcall_lambda, mark_backtrace): Likewise.
14648 * fns.c (concat): Likewise.
14649 * frame.c (x_set_frame_parameters): Likewise.
14650 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14651 0 if not found, not -1. All callers changed.
14652
14653 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14654 (stack_copy_size): Now size_t, not int.
14655 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14656

14661 All callers changed.
14662
14663 * lisp.h (multibyte_char_to_unibyte):
14664 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14665 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14666 * character.h (CHAR_TO_BYTE8):
14667 * cmds.c (internal_self_insert):
14668 * editfns.c (general_insert_function):
14669 * keymap.c (push_key_description):
14670 * search.c (Freplace_match):
14671 * xdisp.c (message_dolog, set_message_1): All callers changed.
14672
14673 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14674
14675 * keyboard.c (safe_run_hook_funcall): New function.
14676 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14677 don't set the hook to nil, but remove the offending function instead.
14678 (Qcommand_hook_internal): Remove, unused.
14679 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14680 Vcommand_hook_internal.
14681
14682 * eval.c (enum run_hooks_condition): Remove.
14683 (funcall_nil, funcall_not): New functions.
14684 (run_hook_with_args): Call each function through a `funcall' argument.
14685 Remove `cond' argument, now redundant.
14686 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14687 (Frun_hook_with_args_until_failure): Adjust accordingly.
14688 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14689
14690 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14691
14692 * dispextern.h (string_buffer_position): Remove declaration.

14698 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14699 All callers changed.
14700
14701 * w32.c (_wsa_errlist): Use braces for struct initializers.
14702

14707 used outside xdisp.c).
14708 (cursor_row_p): Remove parameter `w', unused since
14709 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14737 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
14738 Replace SIGTYPE with void everywhere.
14739 * s/usg5-4-common.h (SIGTYPE): Remove definition.

14741
14742 2011-03-26 Eli Zaretskii <eliz@gnu.org>
14743
14744 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
14745 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
14746
14747 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
14748
14749 * w32.c (read_unc_volume): Use parameter `henum', instead of
14750 global variable `wget_enum_handle'.
14751
14752 * keymap.c (describe_vector): Remove parameters `indices' and
14753 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

14824 Don't pass uninitialized region to CombineRgn.
14825
14826 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
14827
14828 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
14829 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
14830 (Fx_close_connection): Remove unused variable `i'.

14832 * w32font.c (w32font_draw): Return number of glyphs.
14833 (w32font_open_internal): Remove unused variable `i'.
14834 (w32font_driver): Add missing initializer.

14862 Use Frun_hooks.
14863 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14864 unconditionally since it does the check itself.
14865
14866 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14867
14868 Fix more problems found by GCC 4.5.2's static checks.
14869
14870 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14871 the first time through the loop, since we know p0 < p1 then.
14872 This also avoids a gcc -Wstrict-overflow warning.
14873
14874 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14875 leading to a memory leak, possible in functions like
14876 load_charset_map_from_file that can allocate an unbounded number
14877 of objects (Bug#8318).
14878
14879 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14880 that could (at least in theory) be that large.
14881
14882 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14883 This is less likely to overflow, and avoids undefined behavior if
14884 overflow does occur. All callers changed. Use strtoul to scan
14885 for the unsigned long integer.
14886 (pint2hrstr): Simplify and tune code slightly.
14887 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14888
14889 * scroll.c (do_scrolling): Work around GCC bug 48228.
14890 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
14891
14892 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
14893 This also avoids a warning with gcc -Wstrict-overflow.

14895 This also avoids a warning with gcc -Wstrict-overflow.
14896
14897 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14898 fail (Bug#8306).
14899

14901
14902 * process.c (Fmake_network_process): Use socklen_t, not int,
14903 where POSIX says socklen_t is required in portable programs.
14904 This fixes a porting bug on hosts like 64-bit HP-UX, where
14905 socklen_t is wider than int (Bug#8277).
14906 (Fmake_network_process, server_accept_connection):

14919
14920 Make tparam.h and terminfo.c consistent.
14921 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14922 Include tparam.h instead, since it declares them.
14923 * cm.h (PC): Remove extern decl; tparam.h now does this.
14924 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14925 * terminfo.c: Include tparam.h, to check interfaces.
14926 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14927 (tparam): Adjust signature to match interface in tparam.h;
14928 this removes some undefined behavior. Check that outstring and len
14929 are zero, which they always are with Emacs.
14930 * tparam.h (PC, BC, UP): New extern decls.
14931
14932 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

14948 avoid shadowing.
14949 (composition_reseat_it): Remove unused locals.
14950 (find_automatic_composition, composition_adjust_point): Likewise.
14951 (composition_update_it): Mark var as initialized.
14952 (find_automatic_composition): Mark vars as initialized,
14953 with a FIXME (Bug#8290).

14958 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14959 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14960 to avoid shadowing.
14961

14963
14964 * intervals.c (interval_start_pos): Now static.
14965
14966 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

14969 Rename locals to avoid shadowing.
14970
14971 * sound.c (wav_play, au_play, Fplay_sound_internal):
14972 Fix pointer signedness.
14973 (alsa_choose_format): Remove unused local var.
14974 (wav_play): Initialize a variable to 0, to prevent undefined
14975 behavior (Bug#8278).
14976
14977 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14978
14979 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14980
14981 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14982 clobbering (Bug#8298).
14983 * sysdep.c (sys_subshell): Likewise.
14984 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14985
14986 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14987 This should get cleaned up, so that child_setup has the
14988 same signature on all platforms.
14989
14990 * callproc.c (call_process_cleanup): Now static.
14991 (relocate_fd): Rename locals to avoid shadowing.
14992
14993 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14994
14995 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14996 not to be necessary, and produces flickering.
14997
14998 2011-03-20 Glenn Morris <rgm@gnu.org>
14999
15000 * config.in: Remove file.
15001
15002 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
15003
15004 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
15005 are now in src/globals.h.
15006 (syms_of_minibuf): Remove spurious & from previous change.
15007
15008 2011-03-20 Leo Liu <sdl.web@gmail.com>
15009
15010 * minibuf.c (completing-read-function): New variable.
15011 (completing-read-default): Rename from completing-read.
15012 (completing-read): Call completing-read-function.
15013
15014 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
15015
15016 * xfaces.c (Fx_load_color_file):

15032 (sigchld_handler): Now static.
15033
15034 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
15035 That way, the code declares only the vars that it needs.

15053 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
15054
15055 * deps.mk (unexalpha.o): Remove; unused.

15080 warning when compiling print.c.
15081
15082 * font.c (font_unparse_fcname): Abort in an "impossible" situation
15083 instead of using an uninitialized var.

15120 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
15121 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
15122 some of which prompt warnings from gcc -Wbad-function-cast.
15123 (Fformat_time_string, Fencode_time, Finsert_char):
15124 (Ftranslate_region_internal, Fformat):
15125 Rename or remove local vars to avoid shadowing.
15126 (Ftranslate_region_internal): Mark var as initialized.
15127
15128 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
15129 avoid shadowing.
15130
15131 * lisp.h (eassert): Check that the argument compiles, even if
15132 ENABLE_CHECKING is not defined.
15133
15134 * data.c (Findirect_variable): Name an expression, to avoid
15135 gcc -Wbad-function-cast warning.

15146 they're used.
15147 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
15148 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
15149 needed otherwise.

15151 (GC_STRING_CHARS): Remove; not used.
15152 (Fmemory_limit): Cast sbrk's returned value to char *.
15153
15154 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
15155 avoids undefined behavior in theory.
15156
15157 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
15158
15159 Use functions, not macros, for up- and down-casing (Bug#8254).
15160 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15161 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
15162 to use the following functions instead of these macros.
15163 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
15164 EMACS_INT, since callers assume the returned value fits in int.
15165 (upcase1): Likewise, for UPCASE_TABLE.
15166 (uppercasep, lowercasep, upcase): New static inline functions.
15167 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

15171 Rename locals to avoid shadowing.
15172 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
15173 (regex_compile, re_search_2, re_match_2_internal):
15174 Remove unused local vars.
15175 (FREE_VAR): Rewrite so as not to use empty "else",
15176 which gcc can warn about.
15177 (regex_compile, re_match_2_internal): Mark locals as initialized.
15178 (RETALLOC_IF): Define only if needed.
15179 (WORDCHAR_P): Likewise. This one is never needed, but is used
15180 only in a comment talking about a compiler bug, so put inside
15181 the #if 0 of that comment.
15182 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
15183 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
15184 Remove; unused.
15185
15186 * search.c (boyer_moore): Rename locals to avoid shadowing.

15191
15192 * dired.c (compile_pattern): Move decl from here ...
15193 * lisp.h: ... to here, so that it can be checked.
15194 (struct re_registers): New forward decl.
15195
15196 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
15197
15198 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
15199 All uses changed.
15200 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
15201 Rename locals to avoid shadowing.
15202 (Fvertical_motion): Mark locals as initialized.
15203
15204 * casefiddle.c (casify_object, casify_region): Now static.
15205 (casify_region): Mark local as initialized.
15206
15207 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
15208
15209 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
15210 New macros, so that the caller can use some names other than
15211 gcpro1, gcpro2, etc.
15212 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15213 of the new macros.
15214 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15215 argument, for consistency with GCPRO2_VAR, etc: it is now the
15216 prefix of the variable, not the variable itself. All uses
15217 changed.
15218 * dired.c (directory_files_internal, file_name_completion):
15219 Rename locals to avoid shadowing.
15220
15221 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15222 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15223 dired.c's scmp function, had undefined behavior.
15224 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15225 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15226 * buffer.h: ... to here, because these macros use current_buffer,
15227 and the new implementation with inline functions needs to have
15228 current_buffer in scope now, rather than later when the macros
15229 are used.
15230 (downcase, upcase1): New static inline functions.
15231 (DOWNCASE, UPCASE1): Reimplement using these functions.
15232 This avoids undefined behavior in expressions like
15233 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15234 from race conditions in accessing the global variables
15235 case_temp1 and case_temp2.
15236 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15237 * lisp.h (case_temp1, case_temp2): Remove their decls.
15238 * character.h (ASCII_CHAR_P): Move from here ...
15239 * lisp.h: ... to here, so that the inline functions mentioned
15240 above can use them.
15241
15242 * dired.c (directory_files_internal_unwind): Now static.
15243
15244 * fileio.c (file_name_as_directory, directory_file_name):
15245 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
15246 Now static.
15247 (file_name_as_directory): Use const pointers when appropriate.
15248 (Fexpand_file_name): Likewise. In particular, newdir might
15249 point at constant storage, so make it a const pointer.
15250 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
15251 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15252 signedness issues.
15253 (Fset_file_times, Finsert_file_contents, auto_save_error):
15254 Rename locals to avoid shadowing.
15255
15256 * minibuf.c (choose_minibuf_frame_1): Now static.
15257 (Ftry_completion, Fall_completions): Rename or remove locals
15258 to avoid shadowing.
15259
15260 * marker.c (bytepos_to_charpos): Remove; unused.
15261
15262 * lisp.h (verify_bytepos, count_markers): New decls,
15263 so that gcc does not warn that these functions aren't declared.
15264
15265 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
15266 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
15267 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
15268 (copy_text): Remove unused local var.
15269
15270 * filelock.c (within_one_second): Now static.
15271 (lock_file_1): Rename local to avoid shadowing.
15272
15273 * buffer.c (fix_overlays_before): Mark locals as initialized.
15274 (fix_start_end_in_overlays): Likewise. This function should be
15275 simplified by using pointers-to-pointers, but that's a different
15276 matter.
15277 (switch_to_buffer_1): Now static.
15278 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15279 (report_overlay_modification): Rename locals to avoid shadowing.
15280
15281 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
15282 Fix pointer signedness issue.
15283 (sys_subshell): Mark local as volatile if checking for lint,
15284 to suppress a gcc -Wclobbered warning that does not seem to be right.
15285 (MAXPATHLEN): Define only if needed.
15286
15287 * process.c (serial_open, serial_configure): Move decls from here ...
15288 * systty.h: ... to here, so that they can be checked.
15289
15290 * fns.c (get_random, seed_random): Move extern decls from here ...
15291 * lisp.h: ... to here, so that they can be checked.
15292
15293 * sysdep.c (reset_io): Now static.
15294 (wait_for_termination_signal): Remove; unused.
15295
15296 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
15297 (copy_keymap_item, append_key, push_text_char_description):

15683 Move these decls to tparam.h, and make them agree with what
15684 is actually in tparam.c. The previous trick of using incompatible
15685 decls in different modules does not conform to the C standard.

15688 Use const pointers where appropriate.
