3 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4 * w32.c (init_environment): Change the default values of many
5 environment variables in dflt_envvars[] to NULL, to avoid pushing
6 them into environment when they were not already defined. Remove
7 the code that deletes site-lisp subdirectories from the default
8 value of EMACSLOADPATH, as it is no longer needed.
9 (check_windows_init_file): Now external, not static. Use
10 Vload_path as is, without adding anything, as this function is now
11 called when Vload_path is already set up.
13 * w32.h (check_windows_init_file): Add prototype.
15 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
16 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
17 compatibility with Posix platforms.
18 (main): Move the call to check_windows_init_file to here from
20 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
21 any, in the DEFALT argument into the root of the Emacs build or
22 installation tree, as appropriate.
24 * callproc.c (init_callproc_1): Call decode_env_path instead of
25 doing its equivalent by hand.
26 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
27 the code that sets Vexec_path run on MS-Windows.
29 * lread.c (init_lread): Add comments to #ifdef's.
31 * msdos.c (dos_set_window_size, IT_update_begin)
32 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
33 instead of direct references.
35 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
37 Export DEFAULT_REHASH_* to GDB.
38 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
39 Now constants, not macros.
41 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
43 Remove unnecessary casts involving pointers.
44 These casts are no longer needed now that we assume C89 or later,
45 since they involve casting to or from void *.
46 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
47 (make_pure_float, make_pure_vector):
48 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):
49 * macros.c (Fstart_kbd_macro):
50 * menu.c (find_and_return_menu_selection):
51 * minibuf.c (read_minibuf_noninteractive):
52 * sysdep.c (closedir):
53 * xdisp.c (x_produce_glyphs):
54 * xfaces.c (compare_fonts_by_sort_order):
55 * xfns.c (x_real_positions, select_visual):
56 * xselect.c (x_stop_queuing_selection_requests)
57 (x_get_window_property, x_get_window_property_as_lisp_data):
58 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
59 Remove unnecessary pointer casts.
60 * alloc.c (record_xmalloc): New function.
61 * lisp.h (record_xmalloc): New decl.
62 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
63 more like a function. This is because the pointer cast is not
64 needed. All uses changed.
65 * print.c (print_string, print_error_message): Avoid length recalc.
67 Improve fix for macroexp crash with debugging (Bug#12118).
68 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
69 ARRAY_MARK_FLAG when checking subscripts, because ASET is
70 not supposed to be invoked from the garbage collector.
71 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
72 (gc_aset): New function, which is like ASET but can be
73 used in the garbage collector.
74 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
75 (set_hash_index): Use it instead of ASET.

82 (revert_to_self): Forward declarations of static functions.
83 <static BOOL g_b_init_get_security_info>:
84 <g_b_init_create_symbolic_link>: New static flags.
85 (globals_of_w32): Initialize them to zero.
86 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
87 (map_w32_filename): Improve commentary. Simplify switch.
88 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
89 headers (most versions of MinGW w32api don't).
90 (get_security_info, create_symbolic_link)
91 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
93 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
94 in the argument file name.
95 (sys_access): Call unc_volume_file_attributes only if
96 GetFileAttributes fails with network-related error codes.
97 (sys_rename): Diagnose renaming of a symlink when the user doesn't
98 have the required privileges.
99 (get_file_security_desc_by_name): Renamed from
100 get_file_security_desc.
101 (stat_worker): New function, with most of the guts of 'stat', and
102 with addition of handling of symlinks and support for 'lstat'. If
103 possible, get file's attributes and security information by
104 handle, not by name. Produce S_IFLNK bit for symlinks, when
106 (stat, lstat): New functions, call 'stat_worker'.
107 (symlink, readlink, careadlinkat): Rewritten to create and resolve
108 symlinks when the underlying filesystem supports them.
110 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
112 Fix macroexp crash on Windows with debugging (Bug#12118).
113 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
114 checking subscripts; problem introduced with the recent
115 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
116 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
117 since it's used in non-static inline functions now.
119 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
120 Don't assume buffer size fits in 'int'. Remove unused local.
122 Use C99-style 'extern inline' if available.
123 * buffer.h (BUFFER_INLINE):
124 * category.h (CATEGORY_INLINE):
125 * character.h (CHARACTER_INLINE):
126 * charset.h (CHARSET_INLINE):
127 * composite.h (COMPOSITE_INLINE):
128 * dispextern.h (DISPEXTERN_INLINE):

136 * buffer.c (BUFFER_INLINE):
137 * category.c (CATEGORY_INLINE):
138 * character.c (CHARACTER_INLINE):
139 * charset.c (CHARSET_INLINE):
140 * composite.c (COMPOSITE_INLINE):
141 * dispnew.c (DISPEXTERN_INLINE):
142 * sysdep.c (SYSTIME_INLINE):
143 Define to EXTERN_INLINE, so that the corresponding functions
144 are compiled into code.
145 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
146 (INLINE_HEADER_END): New macros.
147 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,
148 since it's used in non-static inline functions now.
149 (VALMASK) [!USE_LSB_TAG]: Likewise.
151 2012-08-02 Glenn Morris <rgm@gnu.org>
153 * s/: Remove empty directory.
155 * s/ms-w32.h: Move to ../nt/inc.

167 hard-coding the path separator.
169 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
171 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
172 This how ASET and AREF are supposed to work, and makes
173 it easier to think about future improvements. See
174 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
175 * charset.h (set_charset_attr): New function.
176 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
177 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

429 does that unconditionally. Remove file, which is now empty.
431 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
434 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

555 w32_console_unicode_input.
556 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
557 (w32_kbd_patch_key, key_event): Use the codepage returned by

579 2012-07-27 Michael Albinus <michael.albinus@gmx.de>
581 * dbusbind.c (XD_DBUS_VALIDATE_BUS_ADDRESS): Canonicalize session
583 (xd_close_bus, Fdbus_init_bus): Handle reference counter properly.
585 2012-07-27 Eli Zaretskii <eliz@gnu.org>
587 * alloc.c (listn): Fix the order the arguments are consed onto the
590 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
591 enumeration constants, as PURE and HEAP are too general, and clash
592 with other headers and sources, such as gmalloc.c and the
593 MS-Windows system headers. All users changed.
595 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
597 Revert last save_excursion_save and save_excursion_restore changes.
598 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

610 Improve GDB symbol export (Bug#12036).
611 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
612 arms of an 'if', not using conditional expressions; otherwise GDB
613 complains about the types in the unevaluated arm when the argument
614 is an integer literal.
615 (xgetint): Simplify expression.
616 * alloc.c (gdb_make_enums_visible): New constant. This ports to
617 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
618 Zaretskii in <http://bugs.gnu.org/12036#13>.
619 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
620 needed now that we have gdb_make_enums_visible.
621 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)

665 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
666 emacs.c, as this is a more-suitable home. Had this been done earlier
667 the fix for 12036 would have avoided some of the problems noted in
668 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
669 would have been more obvious.
670 * emacs.c: Do not include <verify.h>; no longer needed.
671 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
672 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
673 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

679 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
680 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
681 not be usable in #if. This simplifies things.
683 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
685 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
687 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

690 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
691 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
692 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
693 Adjust to changes in lisp.h and emacs.c, by using
694 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
695 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
696 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
697 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
698 instead of gdb_valbits.
699 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
700 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
701 instead of gdb_array_mark_flag.
702 (xboolvector): Get size from $->size, not $->header.size.
703 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
704 (xreload, hook-run, hookpost-run): Remove.
705 * emacs.c: Include <verify.h>.
706 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
707 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
709 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
710 (gdb_USE_LSB_TAG): New enum constants.
711 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
712 Also define these as enum constants, so they're visible to GDB.

714 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
715 as constants, so they're visible to GDB.
716 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
717 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
718 Now enum constants, not macros, so they're visible to GDB.
719 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
720 more convenient now. All uses changed.
721 (VALMASK) [USE_LSB_TAG]: Also define in this case.
722 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
724 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

729 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
731 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
732 add argument, tune behavior, and adjust all callers.
734 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
736 Use typedef for EMACS_INT, EMACS_UINT.
737 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
738 than macros. This simplifies debugging in the usual case, since
739 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
740 and it allows expressions involving EMACS_INT casts.
741 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
743 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
745 * nsterm.m (ns_read_socket): Return early if there is a modal

755 Adjust buffer text indirection counters at the end of Fkill_buffer.
756 * buffer.c (Fkill_buffer): Adjust indirection counters when the
757 buffer is definitely dead. This should really fix an issue reported
758 by Christoph Scholtes again. (Bug#12007).
759 (init_buffer_once): Initialize indirection counters of
760 buffer_defaults and buffer_local_symbols (for sanity and safety).
762 2012-07-24 Eli Zaretskii <eliz@gnu.org>
764 * xdisp.c (init_iterator): Don't compute dimensions of truncation
765 and continuation glyphs on tooltip frames, leave them at zero.
766 Avoids continued lines in tooltips. (Bug#11832)
768 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
770 Simplify copy_overlay.
771 * buffer.c (copy_overlay): Simplify. Use build_marker.

777 or invalid. (Bug#12025)
779 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
780 it signals an error when a tooltip frame is being created.
782 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

795 Swap buffer text indirection counters in Fbuffer_swap_text.
796 * buffer.c (Fbuffer_swap_text): Swap indirections too.
797 This avoids crash reported by Christoph Scholtes at
798 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
800 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
802 * nsmenu.m (Popdown_data): New struct.
803 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
805 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
806 (initWithContentRect): Make imgView and contentView non-static
807 and autorelease them. Also autorelease img and matrix (Bug#12005).

825 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
827 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
828 as it's limited by the amount of memory, not by INT_MAX.
830 2012-07-21 Eli Zaretskii <eliz@gnu.org>
832 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
833 in special-event-map. See the discussion at

859 (compact_buffer): If ENABLE_CHECKING, verify indirection counters.
860 (Fkill_buffer): Adjust indirection counters as needed, don't walk
861 through buffer list if indirection counter is 0.

892 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
893 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
894 Adjust users accordingly.
895 * font.h (font_open_by_name): Adjust prototype.
897 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

913 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
914 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
915 'for_each_per_buffer_object_at'.
916 All uses changed. It's better to use upper-case for macros that
917 cannot be implemented as functions, to give the reader a clue
918 that they're special.
920 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
922 * alloc.c (Fgarbage_collect): Tweak docstring.

1556 * s/aix4-2.h (unix): Remove; no longer needed.
1558 EMACS_TIME simplification (Bug#11875).
1559 This replaces macros (which typically do not work in GDB)
1560 with functions, typedefs and enums, making the code easier to debug.
1561 The functional style also makes code easier to read and maintain.
1562 * systime.h: Include <sys/time.h> on all hosts, not just if
1563 WINDOWSNT, since 'struct timeval' is needed in general.

1575 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
1576 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1577 not functions. All uses rewritten to use the following, respectively:
1578 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1579 (add_emacs_time, sub_emacs_time): New functions.
1580 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
1581 * fileio.c (Fcopy_file):
1582 * xterm.c (XTflash): Get the current time closer to when it's used.
1583 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

1598 (menu_separator_name_p):
1599 * nsmenu.m (ns_update_menubar):
1600 Prefer memcmp to strncmp when either will do.
1601 * nsterm.m: Include <ftoastr.h>.
1603 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1604 Prefer snprintf to strncpy.
1605 * nsterm.m (ns_term_init):
1606 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1607 * nsterm.m (ns_term_init):
1608 Avoid the need for strncpy, by using build_string or
1609 make_unibyte_string directly. Use dtoastr, not snprintf.
1610 * process.c (Fmake_network_process): Diagnose service names that
1611 are too long, rather than silently truncating them or creating
1612 non-null-terminated names.
1613 (Fnetwork_interface_info): Likewise, for interface names.
1614 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1615 Prefer sprintf to strncat.

1622 Clarify fallback case.
1624 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

1628 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1629 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1630 where argument type is known to be a Lisp_Cons.

1642 Optimize pure C strings initialization.
1643 * lisp.h (make_pure_string): Fix prototype.
1644 (build_pure_c_string): New function, defined as static inline. This
1645 provides a better opportunity to optimize away calls to strlen when
1646 the function is called with compile-time constant argument.
1647 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1648 argument, adjust users accordingly. Use build_pure_c_string where

1651 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1652 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1654 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1656 Avoid calls to strlen in miscellaneous functions.
1657 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

1663 Avoid calls to strlen in path processing functions.
1664 * fileio.c (file_name_as_directory): Add comment. Change to add
1665 srclen argument and return the length of result. Adjust users
1667 (directory_file_name): Fix comment. Change to add srclen argument,

1681 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1682 We include usg5-4-common.h, which defines them both.
1684 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1685 O_RDONLY already includes it).
1687 Stop ns builds setting the EMACSLOADPATH environment variable.
1688 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1689 Now it does not set EMACSLOADPATH, just returns the load-path string.
1690 * nsterm.h: Update accordingly.
1691 * lread.c [HAVE_NS]: Include nsterm.h.
1692 (init_lread) [HAVE_NS]: Use ns_load_path.

1695 2012-07-09 Glenn Morris <rgm@gnu.org>
1697 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1698 since the included bsd-common.h does so.
1700 Stop ns builds setting the EMACSPATH environment variable.
1701 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1702 (ns_init_paths): Do not set EMACSPATH.
1703 * nsterm.h (ns_exec_path): Add it.
1704 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1707 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1709 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1711 * process.c (wait_reading_process_output): 'waitchannels' was unset
1712 when read_kbd || !NILP (wait_for_cell); fix this.
1714 Add GCC-style 'const' attribute to functions that can use it.
1715 * character.h (char_resolve_modifier_mask):
1716 * keyboard.h (make_ctrl_char):
1717 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

1762 Move marker debugging code under MARKER_DEBUG.
1763 * marker.c (MARKER_DEBUG): Move marker debugging code under
1764 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1765 for bootstrap with --enable-checking (~3x slowdown reported
1766 by Juanma Barranquero <lekktu@gmail.com>).
1767 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1769 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1771 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.

1776 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1777 has no font, use the frame's font. (Bug#11813)
1778 (display_line): Add commentary about displaying truncation glyphs
1780 (produce_special_glyphs): Move here from term.c.
1782 * term.c (produce_special_glyphs): Move to xdisp.c.
1784 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1787 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1789 * xdisp.c (display_line): Avoid warning about implicit declaration
1792 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1794 * lisp.h: Remove empty conditional.
1796 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1798 * lread.c (load_path_check): Now static.
1800 Fix some minor --with-ns problems found by static checking.
1801 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1802 (x_set_font) [!HAVE_X_WINDOWS]:
1803 * image.c (xpm_load_image) [HAVE_NS]:
1804 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1805 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1806 Remove unused local.
1807 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1808 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.

1819 * lread.c (load_path_check): New function, split from init_lread.
1820 (init_lread): Reorganize. Motivation:
1821 If EMACSLOADPATH is set, check/warn about that rather than the
1822 defaults, which we are not going to use. Hence we can remove
1823 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1824 Don't warn if site-lisp directories are missing.
1825 If not installed, start from a blank load-path, since
1826 PATH_LOADSEARCH refers to the eventual installation directories.
1828 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1830 Support truncation and continuation glyphs on GUI frames, when
1831 fringes are disabled. (Bug#11832)

1833 continuation glyphs even if on GUI frames. Adjust
1834 it->last_visible_x on GUI frames when the left or right fringes,
1835 or both, are absent.
1836 (start_display, move_it_in_display_line_to): Handle the case of a
1837 GUI frame without a fringe to display continuation or truncation
1839 (insert_left_trunc_glyphs): Support GUI frames: make sure
1840 truncation glyphs overwrite enough glyphs from the current line to
1841 have sufficient space in pixels.
1842 (display_line): Support truncation and continuation glyphs on GUI
1843 frames. If some spare pixels are left on the line after inserting
1844 the truncation glyphs, fill that space with a stretch glyph of a
1845 suitably computed width.
1847 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1848 produce_glyphs, to support GUI sessions.
1850 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1852 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1854 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1856 Do not require float-time's arg to fit in time_t (Bug#11825).
1857 This works better on hosts where time_t is unsigned, and where
1858 float-time is applied to the (negative) difference between two times.
1859 * editfns.c (decode_time_components): Last arg is now double *,
1860 not int *, and means to store all the result as a double, without
1861 worrying about whether the seconds part fits in time_t.
1862 All callers changed.
1863 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1864 All callers changed.
1865 (Ffloat_time): Do not fail merely because the specified time falls
1866 outside of time_t range.
1868 2012-07-07 Glenn Morris <rgm@gnu.org>
1870 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1881 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1883 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

1885 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1886 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1887 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

1890 * xfont.c (compare_font_names): Redo to omit the need for casts.
1892 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1894 * xfns.c (Fx_change_window_property): Doc fix.
1895 * w32fns.c (Fx_change_window_property): Doc fix.
1897 * w32fns.c (Fx_window_property): Accept the same arguments as the
1898 X Windows version. Doc fix.
1899 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1901 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1902 Eli Zaretskii <eliz@gnu.org>
1904 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1905 Windows-specific code from nt/config.nt moved here.
1906 Obsolete settings removed.
1908 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1910 * process.c: Avoid unnecessary calls to gettime.
1911 (wait_reading_process_output): Don't get the time of day
1912 when gobbling data immediately and not waiting, as there's no need
1913 for it in that case. This removes a FIXME.
1915 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1917 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1918 is defined (Bug#11768).
1920 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1922 Fix marker debugging code.
1923 * marker.c (byte_char_debug_check): Do not perform the check
1924 if buffer is not multibyte.
1925 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1926 Call byte_char_debug_check with correct arguments.
1928 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1930 Compile marker debugging code only if ENABLE_CHECKING is defined.
1931 * marker.c (byte_char_debug_check, count_markers):
1932 Use only if ENABLE_CHECKING is defined.
1933 (byte_debug_flag): Remove.
1934 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1935 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1937 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1939 Avoid code repetition in marker-related functions.
1940 * marker.c (attach_marker): New function.
1941 (Fset_marker, set_marker_restricted, set_marker_both)
1942 (set_marker_restricted_both): Use it.
1943 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1944 Consistently rename charno to charpos.
1945 (marker_position): Add eassert.
1946 (marker_byte_position): Convert to eassert.
1948 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

1958 * lisp.h (build_marker): New prototype.
1959 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1960 * composite.c (autocmp_chars): Likewise.
1961 * editfns.c (buildmark): Remove.
1962 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1963 (save_restriction_save): Use build_marker.
1964 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1965 * window.c (save_window_save): Likewise.
1967 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1969 Do not use Fdelete_overlay in delete_all_overlays
1970 to avoid redundant calls to unchain_overlay.
1971 * buffer.c (drop_overlay): New function.
1972 (delete_all_overlays, Fdelete_overlay): Use it.
1973 * minibuf.c (get_minibuffer): Fix comment.
1975 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1977 Port to OpenBSD 5.1 amd64.
1978 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1979 This is needed for OpenBSD, and should be harmless on all BSD systems.
1980 Also, include <sys/sysctl.h>, as it should be available on all
1981 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1982 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1983 use p_pid member, not kp_proc.pid.
1985 2012-07-06 Glenn Morris <rgm@gnu.org>
1987 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1989 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1991 More xmalloc and related cleanup.
1992 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

1999 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2000 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2002 Omit needless casts involving void * pointers and allocation.
2003 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2004 as the former is more robust if P's type is changed.
2005 Prefer xzalloc to xmalloc + memset 0.
2006 Simplify malloc-or-realloc to realloc.
2007 Don't worry about xmalloc returning a null pointer.
2008 Prefer xstrdup to xmalloc + strcpy.
2009 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2011 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2012 alloca of a constant.
2014 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2016 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2017 hscroll is larger than the line width. Fixes long and futile
2018 looping inside extend_face_to_end_of_line (on a TTY) producing
2019 glyphs that are not needed and thrown away.
2021 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2023 * marker.c (set_marker_restricted_both): Simplify by using
2026 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2028 * editfns.c (region_limit): Simplify by using clip_to_bounds.

2035 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
2036 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
2037 followed by gtk_box_set_homogeneous (Bug#11768).
2038 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2039 (update_theme_scrollbar_width, xg_create_scroll_bar):
2040 Use gtk_scrollbar_new (Bug#11768).
2041 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2042 (is_box_type): New function (Bug#11768).
2043 (xg_tool_item_stale_p): Call is_box_type.
2044 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2045 with default display (Bug#11768).

2049 * xdisp.c (window_hscroll_limited): New function.
2050 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2051 coordinates when window's hscroll is set to insanely large
2054 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2056 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

2115 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2117 * fileio.c (time_error_value): Check the right error number.
2118 Problem reported by Troels Nielsen in
2119 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

2123 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2124 This should be fixed in a better way; see Eli Zaretskii in
2125 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2126 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2128 * fileio.c (time_error_value): Rename from special_mtime.
2129 The old name's problems were noted by Eli Zaretskii in
2130 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2132 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2133 This variable's comment says Emacs needs at least one GDB-visible
2134 symbol of type enum pvec_type, to work around GDB problems.
2135 The symbol's value doesn't matter.
2137 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2138 that causes compilation to fail on pre-C99 compilers.
2140 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2142 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

2151 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2153 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2154 * lisp.h (enum pvec_type): Use fewer bits.
2155 (PSEUDOVECTOR_SIZE_BITS): New constant.
2156 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2157 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2158 change in pvec_type.
2159 (PSEUDOVECTOR_TYPEP): New macro.
2160 (TYPED_PSEUDOVECTORP): Use it.
2161 * fns.c (internal_equal): Adapt code to extract pvectype.
2162 * emacs.c (gdb_pvec_type): Update type.
2163 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2164 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2165 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2166 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2167 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2168 abusing vector->header.next.nbytes.
2169 (live_vector_p): Use PVEC_TYPE.
2170 (mark_object): Adapt code to extract pvectype. Use switch.
2172 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2174 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2175 Tighten new eassert a bit.
2177 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2179 Fix compilation with --enable-gcc-warnings and -O1
2181 * doprnt.c (doprnt): Change type of tem to int, initialize
2182 to avoid compiler warning. Add eassert.
2183 * search.c (simple_search): Initialize match_byte to avoid
2184 compiler warning. Add eassert.
2186 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2188 Avoid weird behavior with large horizontal scrolls.
2189 Without this change, for example, large hscroll values would
2190 mess up Emacs's display on Fedora 15 x86, presumably due to
2191 overflows in int calculations in the display code.
2192 Also, if buffers had long lines, Emacs would freeze.
2193 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2194 (set_window_hscroll): New function, containing the old guts of
2195 Fset_window_hscroll. Return the clipped value.
2196 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2197 This avoids the need to check against PTRDIFF_MAX.
2199 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2201 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

2205 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2207 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2208 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2209 since GCC 4.4.6 issues a bogus warning for them.
2211 Fix bugs in file timestamp newness comparisons.
2212 * fileio.c (Ffile_newer_than_file_p):
2213 * lread.c (Fload): Use full timestamp resolution of files,
2214 not just the 1-second resolution, so that files that are only
2215 slightly newer still count as newer.
2216 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2217 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2219 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2221 * fileio.c: Improve handling of file time marker. (Bug#11852)
2222 (special_mtime): New function.
2223 (Finsert_file_contents, Fverify_visited_file_modtime):
2224 Use it to set special mtime values consistently.
2226 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2228 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2229 marker for non-existing file. (Bug#11852)
2231 2012-07-03 Glenn Morris <rgm@gnu.org>
2233 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2234 and did not make it into globals.h).
2236 2012-07-03 Tom Tromey <tromey@redhat.com>

2274 2012-07-03 Glenn Morris <rgm@gnu.org>
2276 * lisp.h (Frandom): Make it visible to C.
2277 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2278 buffer for invisible buffers. (Bug#1229)

2282 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2283 values which aren't power of 2.
2284 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2285 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2288 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2290 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2292 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2294 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2296 * alloc.c (allocate_vector_block): Remove redundant
2297 calls to mallopt if DOUG_LEA_MALLOC is defined.
2298 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2299 avoid calls to mallopt if zero_vector is returned.
2301 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2303 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2304 is enabled, avoid dereferencing NULL current_sblock if
2307 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2309 Cleanup basic buffer management.
2310 * buffer.h (struct buffer): Change layout to use generic vector
2311 marking code. Fix some comments. Change type of 'clip_changed'
2312 to bitfield. Remove unused #ifndef old.
2313 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2314 (GET_OVERLAYS_AT): Fix indentation.
2315 (for_each_per_buffer_object_at): New macro.
2316 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2317 (Fbuffer_local_variables): Use it.
2318 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2319 * alloc.c (allocate_buffer): Adjust to match new layout of
2320 struct buffer. Fix comment.
2321 (mark_overlay): New function.
2322 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2323 Lisp area of struct buffer.
2324 (mark_object): Use it. Adjust marking of misc objects
2325 and related comments.
2327 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2329 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2330 wrapper that is not needed because the wrapped code is a no-op (zero
2331 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2332 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2334 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2336 * alloc.c (mark_buffer): Simplify. Remove prototype.
2337 (mark_object): Add comment. Reorganize marking of vector-like
2338 objects. Use CHECK_LIVE for all vector-like objects except buffers
2339 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2340 redundant calls to mark_vectorlike for bool vectors.
2342 2012-06-30 Glenn Morris <rgm@gnu.org>
2344 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2346 * epaths.in (PATH_SITELOADSEARCH): New.
2347 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2348 This is rather than relying on --enable-locallisppath elements
2349 having "site-lisp" in their names. (Bug#10208#25, 11658)
2351 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2353 * w32proc.c (sys_select): Accept and ignore one more argument.
2355 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2357 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2358 (pselect) [!MS_DOS]: Redirect to sys_select.
2360 * sysdep.c: Don't include dos.h and dosfns.h.
2362 * process.c (sys_select):
2363 * msdos.c (sys_select): Accept one more argument and ignore it.
2365 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2366 adapt data types and code to that.
2369 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2370 which clashes with the gnulib function of the same name.
2372 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2374 * font.c (font_style_to_value, font_style_symbolic)
2375 (font_prop_validate_style): Add type checks for values in
2378 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2380 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2383 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2385 * xdisp.c (try_window_id): Undo last change.
2387 * w32.c (getwd): Adjust commentary about startup_dir.
2388 (init_environment): Always call sys_access, even in non-MSVC
2389 builds. Don't chdir to the directory of the Emacs executable.
2390 This undoes code from 1997 which was justified by the need to
2391 "avoid conflicts when removing and renaming directories". But its
2392 downside was that every relative file name was being interpreted
2393 relative to the directory of the Emacs executable, which can never
2394 be TRT. In particular, it broke sys_access when called with
2395 relative file names.
2396 (sys_access): Map GetLastError to errno.
2398 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2400 * window.h (struct window): Change type of 'fringes_outside_margins'
2401 to bitfield. Fix comment. Adjust users accordingly.
2402 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2404 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2407 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2409 * gnutls.c (emacs_gnutls_handshake):
2410 Add QUIT to make the loop interruptible.
2412 2012-06-29 Glenn Morris <rgm@gnu.org>
2414 * charset.c (init_charset): Make lack of etc/charsets fatal.
2416 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2418 * editfns.c (region_limit): Fix type mismatch.
2420 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2422 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2423 undefined. Convert from xassert to eassert.
2424 * nsmenu.m: Convert from xassert to eassert.
2425 * nsterm.m: Likewise.
2427 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2429 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2431 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2433 Avoid integer overflow on scroll-left and scroll-right.
2434 * window.c (HSCROLL_MAX): New macro.
2435 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2436 overflow when requested scroll falls outside ptrdiff_t range.
2438 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2440 * window.h (struct window): Change type of 'hscroll',
2441 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2442 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2443 Adjust users accordingly.
2444 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2445 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2446 from EMACS_INT to ptrdiff_t.
2447 (make_window): Omit redundant initialization.
2449 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
2451 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
2453 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2455 * window.h (struct window): Change type of 'use_time' and
2456 'sequence_number' from Lisp_Object to int.

2464 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
2465 enabled with --enable-checking=[all,glyphs] configure option.
2466 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2467 adjust comments accordingly.

2516 * alloc.c (allocate_string_data): Remove dead code.
2517 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
2518 avoid GCC warning about unused macro.
2520 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2522 * alloc.c (allocate_string): Omit intervals initialization.
2523 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2524 as in make_pure_string and make_pure_c_string.
2526 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2528 * alloc.c (allocate_string): Fix last change.
2530 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2555 2012-06-26 Eli Zaretskii <eliz@gnu.org>
2557 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
2558 _stricmp and _strnicmp.
2559 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.

2576 * term.c (delete_tty): Remove redundant call to memset.
2578 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
2580 * alloc.c: Remove build_string.
2581 * lisp.h: Define build_string as static inline. This provides
2582 a better opportunity to optimize away calls to strlen when the
2583 function is called with compile-time constant argument.
2584 * image.c (imagemagick_error): Convert to build_string.
2585 * w32proc.c (sys_spawnve): Likewise.
2586 * xterm.c (x_term_init): Likewise.
2588 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2590 Use sprintf return value instead of invoking strlen on result.
2591 In the old days this wasn't portable, since some sprintf
2592 implementations returned char *. But they died out years ago and
2593 Emacs already assumes sprintf returns int.
2594 Similarly for float_to_string.
2595 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2596 * ccl.c (ccl_driver):
2597 * character.c (string_escape_byte8):
2598 * data.c (Fnumber_to_string):

2600 * print.c (print_object):
2601 * xdisp.c (message_dolog):
2602 * xfns.c (syms_of_xfns):
2603 Use sprintf or float_to_string result to avoid need to call strlen.
2604 * data.c (Fnumber_to_string):
2605 Use make_unibyte_string, since the string must be ASCII.
2606 * lisp.h, print.c (float_to_string): Now returns int length.
2607 * term.c (produce_glyphless_glyph):
2608 Use sprintf result rather than recomputing it.
2610 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2611 * Makefile.in (ALL_CFLAGS):
2612 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
2613 * gmalloc.c, regex.c: Include <config.h> unconditionally.

2617 * dispextern.h (xstrcasecmp): Define to library function
2618 strcasecmp if available.
2619 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
2621 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
2623 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):
2624 Avoid comma operator.

2634 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
2636 * gtkutil.c (get_utf8_string): Remove redundant assignment.
2637 sprintf already null-terminates its output.
2639 * xfns.c (x_window): Remove redundant cast.
2641 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2643 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
2644 `const char *' to `char *' to avoid compiler warning.
2646 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2648 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2649 instead of truncating it to 63 (admittedly a generous limit).
2651 * process.c: Fix spelling and caps in comments.
2653 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2655 * emacs.c (setpgrp): Remove definition, unused.

2665 (SYSTIME_H): Add nt/inc/sys/time.h.
2667 * systime.h [WINDOWSNT]: Include sys/time.h.
2669 * s/ms-w32.h (struct timespec): Definition moved from
2670 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
2672 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

2702 Remove unnecessary forward decls.
2704 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2706 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
2707 * lisp.h (WAIT_READING_MAX): New macro.
2708 * dispnew.c (Fsleep_for, sit_for):
2709 * keyboard.c (kbd_buffer_get_event):
2710 * process.c (Faccept_process_output):
2711 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2712 This improves on the previous patch, which introduced a bug
2713 when time_t is unsigned and as wide as intmax_t.
2714 See <http://bugs.gnu.org/9000#51>.
2716 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2723 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
2725 * makefile.w32-in: Update dependencies.
2727 * w32.c (ltime): Add return type and declare static.
2728 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
2730 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
2732 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2733 Privately reported by Herbert J. Skuhra.
2734 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2736 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
2737 not make_lisp_timeval, when the argument is of type EMACS_TIME.
2739 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2741 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
2742 last argument of make_unibyte_string.
2744 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
2745 language ID in the event parameters.
2747 * w32term.c (w32_read_socket): Put the new keyboard codepage into
2748 event.code, not the obscure "character set ID".
2750 2012-06-23 Chong Yidong <cyd@gnu.org>
2752 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
2754 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2756 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
2757 * w32.c (fdutimens): New function.
2759 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
2761 * s/ms-w32.h (pselect): Redirect to sys_select.
2763 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.

2767 use_relocatable_buffers.
2769 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
2771 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2772 Privately reported by Herbert J. Skuhra.
2773 [__FreeBSD__]: Remove "*/" typo after "#include".
2774 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
2775 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.

2779 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2781 Support higher-resolution time stamps (Bug#9000).
2782 The time stamps are only nanosecond-resolution at the C level,
2783 since that's the best that any real-world system supports now.
2784 But they are picosecond-resolution at the Lisp level, as that's
2785 easy, and leaves room for future OS improvements.
2787 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2790 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2791 Don't get current time unless it's needed.
2793 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2794 now provides it if it's absent.
2795 (start_atimer): Port to higher-res time stamps.
2796 Check for time stamp overflow. Don't get current time more
2797 often than is needed.
2799 * buffer.h (struct buffer): Buffer modtime now has high resolution.

2845 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2846 Port to higher-resolution time stamps. Do not assume time_t is signed.
2847 (decode_timer): New function. Timers are now vectors of length 9,
2848 not 8, to accommodate the picosecond component.
2849 (timer_check_2): Use it.
2851 * nsterm.m (select_timeout, timeval_subtract): Remove.
2852 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,

2855 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2856 * nsterm.h (ns_select): Adjust prototype.

2860 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2862 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2864 * lisp.h (time_overflow): New decl.
2865 (wait_reading_process_output): First arg is now intmax_t, not int,

2878 (Fprocess_attributes): Now generates ns-resolution time stamps.
2880 * sysdep.c: Include utimens.h. Don't include utime.h
2881 or worry about struct utimbuf; gnulib does that for us now.

2883 (make_timeval): New function.
2884 (set_file_times): Now sets ns-resolution time stamps.

2888 Now returns ns-resolution time stamp. All uses changed.
2889 Check for time stamp overflow.
2891 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2892 provides a substitute now.
2894 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2895 since it guarantees struct timespec.
2896 (EMACS_TIME): Now struct timespec, so that we can support
2897 ns-resolution time stamps.
2898 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2899 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2900 (EMACS_USECS): Remove.
2901 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2902 so multiply the arg by 1000 before storing it.
2903 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2905 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

2912 (make_timeval, make_lisp_time, decode_time_components): New decls.
2913 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2914 that it mishandled time_t overflow. You can't compare by subtracting!
2915 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2916 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

2943 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2944 (timeval_subtract): Remove; no longer needed.
2945 (XTflash, XTring_bell, x_wait_for_event):
2946 Port to ns-resolution time stamps. Don't assume time_t is signed.

2952 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2954 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2955 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2956 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2957 staticidx goes up to 1597 out of 1600 = 0x640.)
2959 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2961 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2962 Otherwise, the umask might be mistakenly 0 while handling input signals.

2995 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2996 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2997 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2998 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

3007 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3008 gets killed during executing of this function (Bug#11665).
3009 Try to always return Qt when the buffer has been actually killed.
3010 (Vkill_buffer_query_functions): In doc-string say that functions
3011 run by this hook should not change the current buffer.
3013 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3015 Fix recently-introduced process.c problems found by static checking.
3016 * process.c (write_queue_push, write_queue_pop, send_process):

3036 This removes the need for CHECK.
3037 (CHECK): Remove. Its comments about always evaluating its
3038 argument were confusing, as 'eassert' typically does not evaluate
3041 * coding.c (produce_chars): Use ptrdiff_t, not int.
3043 * xterm.c (x_draw_underwave): Check for integer overflow.
3044 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3377 * doprnt.c (doprnt): Truncate multibyte char correctly.
3378 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3379 would mishandle a string argument "Xc" if X was a multibyte
3380 character of length 2: it would truncate after X's first byte
3381 rather than including all of X.
3383 2012-06-06 Chong Yidong <cyd@gnu.org>
3385 * buffer.c (word_wrap): Doc fix.

3440 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3443 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3445 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3447 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3449 For a 'struct window', replace some Lisp_Object fields to
3450 bitfields where appropriate, remove unused fields.
3451 * window.h (struct window): Remove unused 'last_mark_x' and
3452 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3453 change it's type from Lisp_Object to bitfield.
3454 Change type of 'force_start', 'optional_new_start',
3455 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

3462 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3463 Use 'float' consistently, rather than 'float' in most places
3464 and 'double' in a couple of places.
3466 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3468 * xdisp.c (handle_stop): Detect whether we have overlay strings
3469 loaded by testing it->current.overlay_string_index to be
3470 non-negative, instead of checking whether n_overlay_strings is
3471 positive. (Bug#11587)
3473 2012-05-31 Chong Yidong <cyd@gnu.org>
3475 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

3481 * search.c (search_buffer): Remove calls to
3482 r_alloc_inhibit_buffer_relocation, as it is now called by
3483 maybe_unify_char, which was the cause of relocation of buffer text
3486 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3488 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3489 for the duration of call to load_charset, to avoid problems with
3490 callers of maybe_unify_char that access buffer text through C
3493 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3494 decrement the inhibition flag, instead of just setting or
3497 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3499 Remove obsolete '#define static' cruft.
3500 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3501 This #undef was "temporary" in 2000; it is no longer needed
3502 now that '#define static' has gone away.
3503 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3504 (gray_bitmap_bits): Remove; no longer needed.
3505 All uses replaced with definiens.
3506 * xterm.c: Include "bitmaps/gray.xbm".
3508 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3510 Clean up __executable_start, monstartup when --enable-profiling.
3511 The following changes affect the code only when profiling.
3512 * dispnew.c (__executable_start): Rename from safe_bcopy.
3513 Define only on platforms that need it.
3514 * emacs.c: Include <sys/gmon.h> when profiling.
3515 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

3517 (safe_bcopy): Remove decl; no longer has that name.
3518 (main): Coalesce #if into single bit of code, for simplicity.

3548 Do not create empty overlays with the evaporate property (Bug#9642).
3549 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3550 Bug#9642, but explicitly check that the buffer the overlay would
3551 be moved to is live and rearrange lines to make sure that errors
3552 will not put the overlay in an inconsistent state.
3553 (Fdelete_overlay): Cosmetics.
3555 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3557 * w32term.c (my_bring_window_to_top): New function.

3571 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3572 This avoids undefined behavior that might cause the eassert
3573 to not catch an out-of-range value.
3575 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3577 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3591 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3592 Only r_alloc_inhibit_buffer_relocation needed to be added;
3593 the others were already declared.
3595 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3596 before checking whether it's out of range. Put the check inside
3598 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

3616 * search.c (search_buffer): Use it to inhibit relocation of buffer
3617 text while re_search_2 is doing its job, because re_search_2 is
3618 passed C pointers to buffer text. (Bug#11519)
3620 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3623 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

3628 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3631 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3633 Fix coding-related core dumps with gcc -ftrapv.
3634 The code was computing A - B, where A and B are pointers, and B is
3635 random garbage. This can lead to core dumps on platforms that
3636 have special pointer registers, and it also leads to core dumps on
3637 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3638 A - B only when B is initialized properly.
3639 * coding.c (coding_set_source, coding_set_destination): Return void.
3640 (coding_change_source, coding_change_destinations): New functions,
3641 with the old behaviors of coding_set_source and coding_set_destination.

3646 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3648 2012-05-26 Eli Zaretskii <eliz@gnu.org>

3651 * xdisp.c (draw_row_with_mouse_face):
3652 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3654 * w32console.c: Include window.h.
3655 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3657 (initialize_w32_display): Initialize mouse-highlight data.
3659 * w32inevt.c: Include termchar.h and window.h.
3660 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3661 moves, call note_mouse_highlight. If help_echo changed, call
3662 gen_help_event to produce help-echo message in the echo area.
3663 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3666 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3668 * lread.c (read1): Simplify slightly to avoid an overflow warning
3669 with GCC 4.7.0 on x86-64.
3671 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3673 * bidi.c (bidi_mirror_char): Revert last change: an int is
3674 definitely wide enough here.

3689 (allocate_pseudovector):
3690 Use int, not EMACS_INT, where int is wide enough.

3708 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3709 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3710 (Foverlay_recenter, last_overlay_modification_hooks_used)
3711 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3712 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3719 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3720 Omit pointer cast, which isn't needed anyway, and doesn't work
3721 after the EMACS_INT -> ptrdiff_t change.
3722 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3723 * buffer.h: Adjust decls to match defn changes elsewhere.

3728 not int, to avoid needless 32-bit limit on 64-bit hosts.
3729 (exec_byte_code): Use tighter memory-full test, one that checks
3730 for alloca overflow. Don't compute the address of the object just
3731 before an array, as that's not portable. Use EMACS_INT, not
3732 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3733 * callint.c (Fcall_interactively):
3734 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3745 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3746 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3747 (casify_object): Avoid integer overflow when overallocating buffer.
3748 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3751 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3752 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3753 integers are now checked earlier. All uses replaced with XINT.
3755 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3756 For CCL_MapSingle, check that content and value are in int range.
3757 (ccl_driver, Fregister_code_conversion_map):
3758 Check that Vcode_version_map_vector is a vector.
3759 (resolve_symbol_ccl_program): Check that vector header is in range.
3760 Always copy the vector, so that we can check its contents reliably
3761 now rather than having to recheck each instruction as it's being
3762 executed. Check that vector words fit in 'int'.
3763 (ccl_get_compiled_code, Fregister_ccl_program)
3764 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3765 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3767 contents are in range.
3768 (Fccl_execute_on_string): Check that status is in range.
3769 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3770 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3771 Accept and return EMACS_INT, not int, because callers can pass values

3778 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3780 avoid mishandling large integers.

3792 Don't assume unsigned int fits into fixnum, or that fixnum fits
3793 into unsigned int. Don't require max_code to be a valid fixnum;
3794 that's not true for gb10830 4-byte on a 32-bit host. Allow
3795 invalid_code to be a cons, for the same reason. Require code_offset
3796 to be a character. Avoid int overflow if max_char is close

3799 this is intended anyway and avoids some undefined behavior.

3801 INDEX_TO_CODE_POINT, as that's what it expects.
3802 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.

3804 this is what was intended anyway, and it avoids undefined behavior.
3805 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3806 integer-overflow issues.

3808 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3809 where the argument is EMACS_INT, and this behavior is not intended.
3810 * chartab.c (Fmake_char_table, Fset_char_table_range)
3811 (uniprop_get_decoder, uniprop_get_encoder):
3812 Don't assume fixnum fits in int.
3813 * cmds.c (move_point): New function, that does the gist of
3814 Fforward_char and Fbackward_char, but does so while checking
3815 for integer overflow more accurately.
3816 (Fforward_char, Fbackward_char): Use it.
3817 (Fforward_line, Fend_of_line, internal_self_insert)
3818 (internal_self_insert):
3819 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4427 (start_hourglass): Use duration_to_sec_usec to do proper
4428 overflow checking on durations.
4429 * xfaces.c (Fbitmap_spec_p):
4430 Check that fixnums are in proper range for system types.
4431 (compare_fonts_by_sort_order):
4432 Avoid mishandling comparisons due to subtraction overflow.

4441 (face_at_string_position):
4442 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4443 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
4444 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
4446 Check that fixnums are in proper range for system types.
4447 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)

4460 (x_get_local_selection, x_reply_selection_request)
4461 (x_handle_selection_request, wait_for_property_change):
4462 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4463 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
4464 short is wide enough.
4465 (x_send_client_event): Don't assume fixnum fits in int.
4466 * xterm.c (x_x_to_emacs_modifiers):
4467 Don't assume EMACS_INT overflows nicely into int.
4468 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
4470 (handle_one_xevent): NATNUMP can eval its arg twice.
4471 (x_connection_closed):
4472 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4473 * xterm.h: Adjust decls to match defn changes elsewhere.
4474 (struct scroll_bar): Use struct vectorlike_header
4475 rather than rolling our own approximation.
4476 (SCROLL_BAR_VEC_SIZE): Remove; not used.
4478 2012-05-25 Glenn Morris <rgm@gnu.org>
4480 * lisp.mk (lisp): Update for more files being compiled now.
4482 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

4485 (read_pure): Remove var.
4486 (unreadpure): Remove function.
4487 (readevalloop): Don't call read_list with -1 flag.
4488 (read1, read_vector): Don't test read_pure any more.
4489 (read_list): Simplify.
4491 * fileio.c, character.h: Minor style tweaks.

4502 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
4505 This directory predates autoconf and is no longer needed nowadays.
4506 Move its few remaining bits of functionality to where they're needed.
4507 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

4515 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
4516 (EMACS_UINT): Define unconditionally now.
4517 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4518 (BITS_PER_EMACS_INT): New constants, replacing
4519 what used to be in config.h, but not useful in #if.
4520 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4521 define them any more.
4522 (VAL_MAX): New macro.
4524 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4525 BITS_PER_EMACS_INT, in #if.
4526 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4527 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4528 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4529 * s/ms-w32.h (DATA_START):
4530 Move here from removed file m/intel386.h.
4531 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4532 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4534 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4536 Assume C89 or later.
4537 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

4544 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4545 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4546 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4547 * xterm.c (input_signal_count): Assume volatile works.
4549 2012-05-21 Ken Brown <kbrown@cornell.edu>
4551 * xgselect.c (xg_select): Fix first argument in call to 'select'
4554 2012-05-20 Ken Brown <kbrown@cornell.edu>
4556 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4557 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4559 2012-05-19 Ken Brown <kbrown@cornell.edu>
4561 * xfns.c (x_in_use): Remove `static' qualifier.
4562 * xterm.h (x_in_use): Declare.
4563 * xgselect.c: Include xterm.h.
4564 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4565 and `display_arg' (bug#9754).
4567 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4569 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4571 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4572 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4574 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4576 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.

4579 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4581 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4582 reference to image_cache->refcount.
4583 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4585 2012-05-17 Juri Linkov <juri@jurta.org>
4587 * search.c (Fword_search_regexp, Fword_search_backward)
4588 (Fword_search_forward, Fword_search_backward_lax)
4589 (Fword_search_forward_lax): Move functions to isearch.el
4590 (bug#10145, bug#11381).
4592 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4594 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4596 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4598 * lread.c (init_obarray): Declare Qt and Qnil as special.
4600 2012-05-14 Glenn Morris <rgm@gnu.org>
4602 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4603 Put "libexec" before "bin", for the sake of init_callproc_1.
4605 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4607 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4609 * unexaix.c: Port to more-recent AIX compilers.
4610 (report_error, report_error_1, make_hdr, copy_sym)
4611 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4612 Make arguments const char *, not char *, to avoid violations of C
4613 standard and to fix some AIX warnings reported by Gilles Pion.
4615 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4617 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4618 already have overlays loaded.
4619 (handle_single_display_spec): Before returning without displaying
4620 fringe bitmap, synchronize the bidi iterator with the main display
4621 iterator, by calling iterate_out_of_display_property.
4622 (iterate_out_of_display_property): Detect buffer iteration by
4623 testing that it->string is a Lisp string.
4624 (get_next_display_element): When the current object is exhausted,
4625 and there's something on it->stack, call set_iterator_to_next to
4626 proceed with what's on the stack, instead of returning zero.
4627 (set_iterator_to_next): If called at the end of a Lisp string,
4628 proceed to consider_string_end without incrementing string
4629 position. Don't increment display vector index past the end of
4630 the display vector. (Bug#11417)
4631 (pos_visible_p): Don't report a position visible when move_it_to
4632 stopped at the last line of window, which happens to be scanned
4633 backwards by the bidi iteration. (Bug#11464)
4635 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4637 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4638 and right-margin display specs even if the spec is invalid or we
4639 are on a TTY, and thus unable to display on the fringes.
4640 That's because the text with the property will not be displayed anyway,
4641 so we need to signal to the caller that this is a "replacing"
4642 display spec. This fixes display when the spec is invalid or we
4645 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4647 * unexaix.c (make_hdr): Fix typo in prototype.
4648 This bug broke the build on AIX. Problem reported by Gilles Pion.
4650 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4652 * keyboard.c (kbd_buffer_get_event): Read special events also in
4653 batch mode. (Bug#11415)
4655 2012-05-12 Glenn Morris <rgm@gnu.org>
4657 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4659 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4661 * lisp.mk (lisp): Add newcomment.elc.
4663 2012-05-12 Glenn Morris <rgm@gnu.org>
4665 * Makefile.in (MKDIR_P): New, set by configure.
4666 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4668 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4670 Remove unused function hourglass_started.
4671 * dispextern.h (hourglass_started):
4672 * w32fns.c (hourglass_started):
4673 * xdisp.c (hourglass_started): Remove.
4675 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4677 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4678 Update dependencies.
4680 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4682 * xgselect.c (xg_select): Put maxfds+1 into a var.
4683 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4685 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4687 2012-05-10 Dave Abrahams <dave@boostpro.com>
4689 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4690 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4692 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4694 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4695 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4696 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4697 Initialize xd_registered_buses.
4699 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4701 Untag more efficiently if USE_LSB_TAG.
4702 This is based on a proposal by YAMAMOTO Mitsuharu in
4703 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4704 For an admittedly artificial (nth 8000 longlist) benchmark on
4705 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4706 Emacs's overall text size by 1%.
4707 * lisp.h (XUNTAG): New macro.
4708 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4709 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4710 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4711 * eval.c (Fautoload):
4712 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4713 * frame.h (XFRAME): Use XUNTAG.
4715 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4716 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4717 Remove unportable assumptions about print widths of types like
4719 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4720 intptr_t when converting between pointer and integer, to avoid GCC
4721 warnings about wrong width.
4723 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4725 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4726 stack for each reader_thread, instead of defaulting to 8MB
4727 determined by the linker. This avoids failures in creating
4728 subprocesses on Windows 7, see the discussion in this thread:
4729 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4731 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4733 Fix up display of the *Minibuf-0* buffer in the mini window.
4734 * keyboard.c (read_char): Don't clear the echo area if there's no
4736 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4737 contents of *Minibuf-0*) if there's no message displayed in its stead.
4739 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4741 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4744 2012-05-06 Chong Yidong <cyd@gnu.org>
4746 * lisp.mk (lisp): Update.
4748 2012-05-05 Jim Meyering <meyering@redhat.com>
4750 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4752 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4754 * data.c (PUT_ERROR): New macro.
4755 (syms_of_data): Use it. Add new error type `user-error'.
4756 * undo.c (user_error): New function.
4757 (Fprimitive_undo): Use it.
4758 * print.c (print_error_message): Adjust print style for `user-error'.
4759 * keyboard.c (user_error): New function.
4760 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4762 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4764 Do not limit current-time-string to years 1000..9999.
4765 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4766 (Fcurrent_time_string): Support any year that is supported by the
4767 underlying localtime representation. Don't use asctime, as it
4768 has undefined behavior for years outside the range -999..9999.
4770 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4772 Fix race conditions involving setenv, gmtime, localtime, asctime.
4773 Without this fix, interrupts could mess up code that uses these
4774 nonreentrant functions, since setting TZ invalidates existing
4775 tm_zone or tzname values, and since most of these functions return
4776 pointers to static storage.
4777 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4778 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4779 Grow the critical sections to include not just invoking
4780 localtime/gmtime, but also accessing these functions' results
4781 including their tm_zone values if any, and any related TZ setting.
4782 (format_time_string): Last arg is now struct tm *, not struct tm **,
4783 so that the struct tm is saved in the critical section.
4784 All callers changed. Simplify allocation of initial buffer, partly
4785 motivated by the fact that memory allocation needs to be outside
4786 the critical section.
4788 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4790 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4791 with RESET_INTERVAL.
4793 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4794 Remove duplicated buffer name initialization.
4796 2012-05-02 Jim Meyering <jim@meyering.net>
4798 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4800 * xfns.c (x_window): Use xstrdup (Bug#11375).
4802 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4804 * xdisp.c (pos_visible_p): If already at a newline from the
4805 display string before the 'while' loop, don't walk back the glyphs
4806 from it3.glyph_row. Solves assertion violation when the display
4807 string begins with a newline (egg.el). (Bug#11367)
4809 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4811 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4814 2012-05-01 Glenn Morris <rgm@gnu.org>
4816 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4817 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4818 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4819 All were removed before 23.1.
4821 * dispnew.c: Remove HAVE_LIBNCURSES test;
4822 it is always true on relevant platforms.
4824 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4825 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4827 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4829 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4831 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4832 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4835 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4837 Do not avoid creating empty evaporating overlays (Bug#9642).
4838 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4839 That is, do not delete an evaporating overlay if it becomes
4840 empty after its bounds are adjusted to fit within its buffer.
4841 This fix caused other problems, and I'm reverting it until we get
4842 to the bottom of them.
4844 2012-04-27 Chong Yidong <cyd@gnu.org>
4846 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4848 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4850 * xdisp.c (pos_visible_p): If the window start position is beyond
4851 ZV, start the display from buffer beginning. Prevents assertion
4852 violation in init_iterator when the minibuffer window is scrolled
4855 * window.c (window_scroll_pixel_based): Likewise.
4857 2012-04-27 Chong Yidong <cyd@gnu.org>
4859 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4861 2012-04-27 Glenn Morris <rgm@gnu.org>
4863 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4864 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4866 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4868 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4869 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4871 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4873 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4874 display element, check also the underlying string or buffer
4875 character. (Bug#11341)
4877 * w32menu.c: Include w32heap.h.
4878 (add_menu_item): If the call to AppendMenuW (via
4879 unicode_append_menu) fails, disable Unicode menus only if we are
4880 running on Windows 9X/Me.

4903 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4905 Do not create empty overlays with the evaporate property (Bug#9642).
4906 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4907 if it becomes empty after its bounds are adjusted to fit within
4908 its buffer. Without this fix, in a nonempty buffer (let ((o
4909 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4910 yields an empty overlay that has the evaporate property, which is
4911 not supposed to happen.

5015 since the two debugging options are incompatible.
5016 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5018 (mem_init, mem_insert, mem_insert_fixup):
5019 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5028 * sysdep.c [__FreeBSD__]: Minor cleanups.
5029 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5030 Use Emacs indenting style more consistently. Avoid some casts.
5031 Use 'double' consistently rather than mixing 'float' and 'double'.

5051 (print_object): Check for cycles even when print-circle is nil and
5052 print-gensym is t, but only check print_depth if print-circle is nil.
5054 2012-04-20 Chong Yidong <cyd@gnu.org>
5056 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5057 set the status to "failed" and ensure that sentinel is run.

5072 farther than the first row after the header line, if any.
5073 Don't consider the header-line row as "partially visible", even if

5112 New extern decls, to avoid calling undeclared functions.
5113 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5114 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5115 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5116 (NEED_MEM_INSERT): New macro.
5117 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5118 Remove one incorrect comment and fix another.

5132 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5133 Remove decls. This fixes an "It stinks!".

5137 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5139 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5155 * s/netbsd.h, s/sol2-6.h:
5156 Remove definition of GC_MARK_STACK, since the default now works.
5157 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5158 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5159 no longer the default.
5160 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5162 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

5185 2012-04-11 Daniel Colascione <dancol@dancol.org>
5187 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5188 against is gone. It's better to use vfork now so that when Cygwin
5189 gains a new, working vfork, we use it automatically (bug#10398).
5191 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5212 being loaded (bug#10424).
5214 2012-04-09 Glenn Morris <rgm@gnu.org>
5216 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

5246 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5248 * xdisp.c (set_cursor_from_row): If the display string appears in
5249 the buffer at position that is closer to point than the position
5250 after the display string, display the cursor on the first glyph of
5251 the display string. Fixes cursor display when a 'display' text
5252 property immediately follows invisible text. (Bug#11094)
5254 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5256 composite.c: use 'double' consistently
5257 * composite.c (get_composition_id): Use 'double' consistently
5258 instead of converting 'float' to 'double' and vice versa; this is
5259 easier to understand and avoids a GCC warning.
5261 2012-04-09 Glenn Morris <rgm@gnu.org>
5263 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5264 preparation for dumping it with emacs. (Bug#4789)

5308 [!WINDOWSNT]: New macros.
5309 (init_libxml2_functions, libxml2_loaded_p): New functions.
5310 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5311 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5312 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5313 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5315 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

5325 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5327 * indent.c (Fvertical_motion): If there is a display string at
5328 point, use it.vpos to compute how many lines to backtrack after
5329 move_it_to point. (Bug#11133)
5331 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5333 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5334 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5335 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5336 macros related to unification of CJK characters. For the details,
5337 see the discussion following the message here:
5338 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5340 2012-04-04 Chong Yidong <cyd@gnu.org>
5342 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5344 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5346 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5347 instead of alloca. (Bug#11138)
5349 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5351 * w32menu.c (is_simple_dialog): Properly check lisp types.
5354 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5356 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5357 position we get to after a call to move_it_to fails the
5358 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5359 only if we wind up in a string from display property. (Bug#11063)
5361 * window.c (Fdelete_other_windows_internal): Invalidate the row
5362 and column information about mouse highlight, so that redisplay
5363 restores it after reallocating the glyph matrices. (Bug#7464)
5365 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5366 string comes from a `display' text property, use the buffer
5367 position of that property as if we actually saw that position in
5369 (move_it_by_lines): Remove the assertion that
5370 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5371 violated when there's a before-string at the beginning of a line.
5374 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5376 * xdisp.c (append_space_for_newline): If the default face was
5377 remapped, use the remapped face for the appended newline.
5378 (extend_face_to_end_of_line): Use the remapped default face for
5379 extending the face to the end of the line.
5380 (display_line): Call extend_face_to_end_of_line when the default
5381 face was remapped. (Bug#11068)
5383 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5385 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5387 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5389 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5391 2012-03-27 Glenn Morris <rgm@gnu.org>
5393 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5396 2012-03-26 Kenichi Handa <handa@m17n.org>
5398 * dispextern.h (struct glyph): Fix previous change. Change the
5399 bit length of glyphless.ch to 25 (Bug#11082).
5401 2012-03-26 Chong Yidong <cyd@gnu.org>
5403 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5404 (command_loop_1): Use it; inhibit selection update for
5405 handle-select-window too (Bug#8996).
5407 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5409 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5411 2012-03-25 Kenichi Handa <handa@m17n.org>
5413 * dispextern.h (struct glyph): Change the bit length of
5414 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5416 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5418 * s/ms-w32.h (tzname): Include time.h before redirecting to
5419 _tzname. Fixes the MSVC build. (Bug#9960)
5421 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5423 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5426 * xterm.c (XTread_socket): Only modify handling_signal if
5427 !SYNC_INPUT. (Bug#11080)
5429 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5431 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5432 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5433 when fetching a multibyte character consumes more bytes than
5434 CHAR_BYTES returns, due to unification of CJK characters in
5435 string_char. (Bug#11073)
5437 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5439 * process.c (wait_reading_process_output): Handle pty disconnect
5440 by refraining from sending oneself a SIGCHLD (bug#10933).
5442 2012-03-22 Chong Yidong <cyd@gnu.org>
5444 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5446 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5447 Mark string as coming from a prefix property.
5448 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5449 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5451 2012-03-21 Chong Yidong <cyd@gnu.org>
5453 * xfaces.c (Vface_remapping_alist): Doc fix.
5455 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5457 * w32proc.c (Fw32_set_console_codepage)
5458 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5461 2012-03-20 Chong Yidong <cyd@gnu.org>
5463 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5464 to reflect default non-nil value of redisplay-dont-pause.
5466 2012-03-19 Kenichi Handa <handa@m17n.org>
5468 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5469 it fit in a valid range (Bug#11003).
5471 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5473 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5474 that is not from display property, accept the row as a "cursor
5475 row" if one of the string's character has a non-nil `cursor'
5476 property. Fixes cursor positioning when there are newlines in
5477 overlay strings, e.g. in icomplete.el. (Bug#11035)
5479 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5481 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5483 2012-03-12 Chong Yidong <cyd@gnu.org>
5485 * eval.c (inhibit_lisp_code): Rename from
5486 inhibit_window_configuration_change_hook; move from window.c.
5488 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5489 * window.c (run_window_configuration_change_hook)
5490 (syms_of_window): Callers changed.
5492 2012-03-11 Chong Yidong <cyd@gnu.org>
5494 * keymap.c (Fkey_description): Doc fix (Bug#9700).
5496 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).

5501 is visible (Bug#10955).
5503 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5505 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5507 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5509 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5510 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5513 2012-03-03 Glenn Morris <rgm@gnu.org>
5515 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5517 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5519 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5520 position past the first glyph_row that ends at ZV. (Bug#10902)
5521 (redisplay_window, next_element_from_string): Fix typos in
5523 (redisplay_window): Pass to move_it_vertically the margin in
5524 pixels, not in screen lines.
5526 2012-03-02 Glenn Morris <rgm@gnu.org>
5528 * buffer.c (buffer-list-update-hook): Doc fix.
5530 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5532 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5533 push_it before setting up the iterator for the first overlay
5534 string, even if we have an empty string loaded.
5535 (next_overlay_string): If there's an empty string on the iterator
5536 stack, pop the stack. (Bug#10903)
5538 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5540 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5541 Suggested by Stefan Monnier in
5542 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5543 * alloc.c (widen_to_Lisp_Object): New static function.
5544 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5545 and widening them to Lisp_Objects. This would work even if
5546 USE_LSB_TAG is defined and wide integers are used, which might
5547 happen in a future version of Emacs.
5549 2012-02-25 Chong Yidong <cyd@gnu.org>
5551 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5554 * xselect.c (Fx_selection_exists_p): Doc fix.
5555 (x_clipboard_manager_save_all): Print an informative message
5556 before saving to clipboard manager.
5558 2012-02-24 Chong Yidong <cyd@gnu.org>
5560 * keyboard.c (process_special_events): Handle all X selection
5561 requests in kbd_buffer, not just the next one (Bug#8869).
5563 2012-02-23 Chong Yidong <cyd@gnu.org>
5565 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5566 call when setting menu-bar-lines and tool-bar-lines parameters.
5567 (unwind_create_frame_1): New helper function.
5569 * window.c (inhibit_window_configuration_change_hook): New var.
5570 (run_window_configuration_change_hook): Obey it.
5571 (syms_of_window): Initialize it.
5573 2012-02-22 Chong Yidong <cyd@gnu.org>
5575 * xterm.c (x_draw_image_relief): Add missing type check for
5576 Vtool_bar_button_margin (Bug#10743).
5578 2012-02-21 Chong Yidong <cyd@gnu.org>
5580 * fileio.c (Vfile_name_handler_alist): Doc fix.
5582 * buffer.c (Fget_file_buffer): Protect against invalid file
5583 handler return value.
5585 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5587 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5588 when computing $valmask.
5590 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5591 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5592 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5593 It's useless in that case, and it can cause problems on hosts
5594 that allocate halves of EMACS_INT values separately.
5595 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5596 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5597 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5598 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5599 it avoids undefined behavior on hosts where shifting right by more
5600 than the word width has undefined behavior.
5602 2012-02-19 Chong Yidong <cyd@gnu.org>
5604 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5605 (Funhandled_file_name_directory, Ffile_name_as_directory)
5606 (Fdirectory_file_name, Fexpand_file_name)
5607 (Fsubstitute_in_file_name): Protect against invalid file handler
5608 return values (Bug#10845).
5610 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5612 * .gdbinit (pitx): Fix incorrect references to fields of the
5615 2012-02-17 Chong Yidong <cyd@gnu.org>
5617 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5619 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5621 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5622 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5624 2012-02-15 Chong Yidong <cyd@gnu.org>
5626 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5627 marked as special. Also, starting docstrings with * is obsolete.
5629 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5631 * gnutls.c (emacs_gnutls_write): Fix last change.
5633 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
5635 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
5638 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5640 * keymap.c (Fsingle_key_description): Handle char ranges.
5642 2012-02-12 Chong Yidong <cyd@gnu.org>
5644 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5645 as that creates a dangerous corner case.
5647 * window.c (Fdelete_window_internal): Invalidate the mouse
5648 highlight (Bug#9904).
5650 2012-02-12 Glenn Morris <rgm@gnu.org>
5652 * xselect.c (Fx_own_selection_internal)
5653 (Fx_get_selection_internal, Fx_disown_selection_internal)
5654 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5655 * nsselect.m (Fx_own_selection_internal)
5656 (Fx_disown_selection_internal, Fx_selection_exists_p)
5657 (Fx_selection_owner_p, Fx_get_selection_internal):
5658 Sync docs and argument specs with the xselect.c versions.
5660 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5662 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5664 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5666 * w32select.c (Fx_selection_exists_p): Sync doc string and
5667 argument list with xselect.c. (Bug#10783)
5669 * w16select.c (Fx_selection_exists_p): Sync doc string and
5670 argument list with xselect.c. (Bug#10783)

5680 2012-02-07 Chong Yidong <cyd@gnu.org>
5682 * buffer.c (Fbuffer_local_variables)
5683 (buffer_lisp_local_variables): Handle unbound vars correctly;
5684 don't let Qunbound leak into Lisp.
5686 2012-02-07 Glenn Morris <rgm@gnu.org>
5688 * image.c (Fimagemagick_types): Doc fix.
5690 * image.c (imagemagick-render-type): Change it from a lisp object
5691 to an integer. Move the doc here from the lisp manual.

5694 2012-02-06 Chong Yidong <cyd@gnu.org>
5696 * doc.c (store_function_docstring): Avoid applying docstring of
5697 alias to base function (Bug#2603).
5699 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5701 * .gdbinit (pp1, pv1): Remove redundant defines.
5704 2012-02-04 Chong Yidong <cyd@gnu.org>
5706 * nsterm.m: Declare a global (Bug#10694).
5708 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5710 * w32.c (get_emacs_configuration_options):
5711 Include --enable-checking, if specified, in the return value.
5713 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5715 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5716 after rounding frame sizes. (Bug#9723)

5720 * keyboard.c (adjust_point_for_property): Don't position point
5721 before BEGV. (Bug#10696)
5723 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5725 Handle overflow when computing char display width (Bug#9496).
5726 * character.c (char_width): Return EMACS_INT, not int.
5727 (char_width, c_string_width): Check for overflow when
5728 computing the width; this is possible now that individual
5729 characters can have unbounded width. Problem introduced
5730 by merge from Emacs 23 on 2012-01-19.
5732 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5734 * dbusbind.c (Fdbus_register_method): Mention the return value

5747 2012-02-02 Kenichi Handa <handa@m17n.org>
5749 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5750 0, do not call append_composite_glyph.
5752 2012-02-02 Kenichi Handa <handa@m17n.org>
5754 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5756 (x_produce_glyphs): If the component of a composition is a null
5757 string, set it->pixel_width to 1 to avoid zero-width glyph.
5759 2012-02-01 Eli Zaretskii <eliz@gnu.org>
5761 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5762 first 2 arguments are identical. This makes inserting large
5763 output from a subprocess an order of magnitude faster on
5764 MS-Windows, where all sbrk'ed memory is always contiguous.
5766 2012-01-31 Glenn Morris <rgm@gnu.org>

5804 2012-01-21 Chong Yidong <cyd@gnu.org>
5806 * floatfns.c (Fcopysign): Make the second argument non-optional,
5807 since nil is not allowed anyway.
5809 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
5811 * process.c (read_process_output): Use p instead of XPROCESS (proc).
5812 (send_process): Likewise.
5814 2012-01-19 Martin Rudalics <rudalics@gmx.at>
5816 * window.c (save_window_save, Fcurrent_window_configuration)

5818 Rewrite doc-strings.
5820 2012-01-19 Kenichi Handa <handa@m17n.org>
5822 * character.c (char_width): New function.
5823 (Fchar_width, c_string_width, lisp_string_width):
5824 Use char_width (Bug#9496).
5826 2012-01-16 Martin Rudalics <rudalics@gmx.at>
5828 * window.c (Vwindow_persistent_parameters): New variable.

6383 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6384 is set, removing the need for VIRT_ADDRESS_VARIES.
6385 (PURE_P): Use a more-efficient implementation that needs just one
6386 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6387 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6388 to 4 (xorl, subq, cmpq, setbe).
6389 * alloc.c (pure): Always extern now, since that's the
6390 VIRT_ADDR_VARIES behavior.
6391 (PURE_POINTER_P): Use a single comparison, not two, for
6392 consistency with the new puresize.h.
6393 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6394 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6400 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6401 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6402 behave as if the cursor position were at the window margin.
6404 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6405 and the cursor position is out of bounds, behave as if the cursor
6406 position were at the window margin. (Bug#10075)
6408 2011-11-18 Chong Yidong <cyd@gnu.org>
6410 * window.c (Fwindow_combination_limit): Make first argument

6432 compute_line_metrics.
6433 (compute_line_metrics): Call row_hash, instead of computing the
6436 * dispnew.c (verify_row_hash): Call row_hash for computing the
6437 hash code of a row, instead of duplicating code from xdisp.c.
6439 * dispextern.h (row_hash): Add prototype.

6475 * image.c (imagemagick_load_image): Fix typo.
6477 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6479 * xdisp.c (display_line): Move the call to
6480 highlight_trailing_whitespace before the call to
6481 compute_line_metrics, since the latter needs to see the final
6482 faces of all the glyphs to compute ROW's hash value.
6483 Fixes assertion violations in row_equal_p. (Bug#10035)
6485 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6487 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6492 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6493 with user-defined heap size. Bump the default size of the temacs
6494 heap to 27MB, to avoid memory warning when running temacs.
6495 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6497 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6544 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6546 Avoid some portability problems by eschewing 'extern inline' functions.
6547 The trivial performance wins aren't worth the portability hassles; see
6548 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6550 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

6552 (window_box_right, window_box_right_offset): Undo previous change,
6553 by removing the "extern"s.
6554 * intervals.c (adjust_intervals_for_insertion)
6555 (adjust_intervals_for_deletion): Undo previous change,
6556 making these static again.
6557 (offset_intervals, temp_set_point_both, temp_set_point)
6558 (copy_intervals_to_string): No longer inline.
6559 * xdisp.c (window_text_bottom_y, window_box_width)

6625 (window_box_right, window_box_right_offset): Declare extern.
6626 Otherwise, these inline functions do not conform to C99 and
6627 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6628 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6629 * intervals.c (adjust_intervals_for_insertion)

6632 (static_offset_intervals): Remove.
6633 (offset_intervals): Rewrite using the old contents of
6634 static_offset_intervals. The old version didn't conform to C99
6635 because an extern inline function contained a reference to an
6636 identifier with static linkage.

6658 (Fwindow_vscroll): Doc fix.
6659 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6660 argument, since it makes no sense to pass a live window and for

6689 (unwind_create_frame): New function (Bug#9943).
6690 (Fx_create_frame): Restructure code to be more similar to the one in
6691 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6692 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6693 Move terminal->reference_count++ just before making the frame official

6794 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6796 * xterm.c: Declare x_handle_net_wm_state to return int.
6797 (handle_one_xevent): Check if we are iconified but don't have
6798 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
6799 (get_current_wm_state): Return non-zero if not hidden,
6800 check for _NET_WM_STATE_HIDDEN (Bug#9893).
6801 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
6802 (x_handle_net_wm_state): Return what get_current_wm_state returns.
6803 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
6805 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6807 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6808 so that this new function doesn't get optimized away by a
6809 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6811 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6813 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6815 2011-10-29 Eli Zaretskii <eliz@gnu.org>
6817 Fix the `xbytecode' command.
6818 * .gdbinit (xprintbytestr): New command.
6819 (xwhichsymbols): Rename from `which'; all callers changed.
6820 (xbytecode): Print the byte-code string as well.
6822 2011-10-29 Kim Storm <storm@cua.dk>
6824 * alloc.c (which_symbols): New function.
6826 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6828 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
6831 2011-10-29 Glenn Morris <rgm@gnu.org>
6833 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6834 Not clear what it was for, and it causes various bugs. (Bug#9839)
6836 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6838 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6839 possible random value that matches one of those tested as
6840 condition to clear the mouse face.
6842 2011-10-28 Chong Yidong <cyd@gnu.org>
6844 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6846 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6848 * window.c (make_window): Initialize phys_cursor_on_p.
6850 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6852 * lisp.h (struct Lisp_Symbol): Update comments.
6854 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6856 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6858 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6860 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6861 <oslsachem@gmail.com> for helping to debug this.
6863 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6864 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6865 (g_b_init_get_glyph_outline_w): New static variables.
6866 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6867 (GetGlyphOutlineW_Proc): New typedefs.
6868 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6869 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6871 (w32font_open_internal, compute_metrics):
6872 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6873 instead of calling the "wide" APIs directly.
6875 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6877 * w32.h (syms_of_w32font): Add prototype.
6879 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6881 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6882 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6883 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6884 (Fmove_to_window_line): Doc fix.
6886 2011-10-27 Chong Yidong <cyd@gnu.org>
6888 * process.c (make_process): Set gnutls_state to NULL.
6890 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6891 non-NULL, regardless of GNUTLS_INITSTAGE.
6892 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6893 an error. Set process slots as soon as we allocate them.
6895 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6897 2011-10-27 Chong Yidong <cyd@gnu.org>
6899 * gnutls.c (emacs_gnutls_deinit): New function.
6900 Deallocate credentials structures as well as calling gnutls_deinit.
6901 (Fgnutls_deinit, Fgnutls_boot): Use it.
6903 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6904 (deactivate_process): Call emacs_gnutls_deinit.
6906 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6908 * image.c (x_create_x_image_and_pixmap):
6909 * w32.c (sys_rename, w32_delayed_load):
6910 * w32font.c (fill_in_logfont):
6911 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6913 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6915 * w32fns.c (w32_default_color_map): New function,
6916 extracted from Fw32_default_color_map.
6917 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6919 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6921 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6923 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6925 * keyboard.c (test_undefined): New function (bug#9751).
6926 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6928 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6930 * sysdep.c (init_sys_modes): Fix the check for the controlling
6931 terminal (Bug#6649).
6933 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6935 * dispextern.h (struct bidi_it): New member next_en_type.
6937 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6938 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6939 current character, check also for next_en_type being WEAK_EN.
6940 (bidi_resolve_weak): Don't enter the expensive loop if the current
6941 position is before next_en_pos. Record the bidi type of the first
6942 non-ET, non-BN character we find, in addition to its position.
6943 (bidi_level_of_next_char): Invalidate next_en_type when
6944 next_en_pos is over-stepped.
6946 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6948 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6949 * editfns.c: Rewrite current-time-zone so that it invokes
6950 the equivalent of (format-time-string "%Z") to get the time zone name.
6951 This fixes a bug when the time zone name contains characters that
6952 need converting from the system time locale to Emacs internal format.
6953 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6954 that patch fixed format-time-string to do the conversion, but
6955 I forgot to fix current-time-zone.
6956 (format_time_string): New function, containing most of
6957 what Fformat_time_string used to contain.
6958 (Fformat_time_string): Rewrite in terms of format_time_string.
6959 This doesn't change this function's behavior.
6960 (current-time-zone): Rewrite to use format_time_string.
6961 This fixes the bug reported by Michael Schierl in
6962 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6963 Jason Rumney's 2007-06-07 change worked around this bug, but
6965 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6967 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6969 * xdisp.c (start_display): If the character at POS is displayed
6970 via a display vector, reset IT->current.dpvec_index to zero.
6971 (try_window_reusing_current_matrix): If a line ends in a display
6972 vector or the next line starts in a display vector, continue
6973 redrawing the window even though the character position of
6974 start_row was reached.
6977 2011-10-18 Chong Yidong <cyd@gnu.org>
6979 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6980 with nobreak-char-display too.
6982 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6984 Fix part 3 of bug#9771.
6985 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6986 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6987 non-neutral characters if the current character is a paragraph
6988 separator (a.k.a. Newline). This avoids running the same
6989 expensive loop twice, once when we consume the preceding newline
6990 and the other time when the line actually needs to be displayed.
6991 Avoid the loop when we see neutrals on the base embedding level
6992 following a character whose directionality is the same as the
6993 paragraph's. This avoids running the expensive loop when a line
6994 ends in a long sequence of neutrals, like control characters.
6995 Add assertion against STRONG_AL type. Slightly rearrange code
6996 that determines the type of a neutral given the first non-neutral
6998 (bidi_level_of_next_char): Set next_en_pos to zero when
6999 invalidating its info.
7001 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7003 * xdisp.c (push_display_prop): Determine whether to record string
7004 or buffer position by IT->string, not by IT->method. Allow
7005 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7006 (move_it_vertically_backward): Don't look for character position
7007 immediately after the newline when in a continuation line.
7010 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7012 * window.c (coordinates_in_window): Rewrite and delabelize
7013 vertical border check. (Bug#5357) (Bug#9618)
7015 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7017 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7018 errors in XSetWindowBorder (bug#9310).
7020 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7022 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7023 avoid crash when xmalloc overrun checking is enabled.
7025 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7027 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7028 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7029 cursor motion with <left> and <right> arrow keys.
7031 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7032 some callers set that themselves.
7034 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7036 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7037 display string and the previous row comes from the same string and
7038 is empty. (Bug#9739) (Bug#9738)
7040 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7042 * doc.c (get_doc_string): Encode file name (bug#9735).
7044 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7046 * bidi.c (bidi_level_of_next_char):
7047 * xdisp.c (get_visually_first_element): Remove old incorrect
7048 comments regarding the Unicode Line Separator character.
7050 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7052 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7054 * alloc.c (Fgc_status): Do not access beyond zombies array
7055 boundary if nzombies > MAX_ZOMBIES.
7056 * alloc.c (dump_zombies): Add missing format specifier.
7058 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7060 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7061 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7063 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7064 Some packages use them to denote characters with modifiers.
7066 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7068 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7069 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7070 matching a pp-number. Rename parameter var to var1.
7072 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7074 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7076 2011-10-08 Glenn Morris <rgm@gnu.org>
7078 * callint.c (Fcall_interactively): Give a more explicit error for the
7079 'c' case with a non-character input. (Bug#8479)
7081 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7083 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7085 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7086 lines that are hscrolled on the left.
7088 * dispnew.c (buffer_posn_from_coords): Account for a possible
7089 presence of header-line. (Bug#4426)
7091 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7093 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7094 Don't advertise functionality which we discourage or doesn't work.
7096 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7098 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7099 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7100 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7101 this makes Emacs dump core during garbage collection on rare
7102 occasions. sizeof is obviously inferior to offsetof here, so
7103 stick with offsetof.
7104 (GC_POINTER_ALIGNMENT): New macro.
7105 (mark_memory): Omit 3rd (offset) arg; caller changed.
7106 Don't assume EMACS_INT alignment is the same as pointer alignment.
7108 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7110 * keyboard.c (read_key_sequence_remapped): New var.
7111 (read_key_sequence): Compute remapping in the right buffer.
7112 (command_loop_1): Use read_key_sequence's remapping directly.
7114 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7116 * dired.c (file_name_completion): Don't expand file name.
7117 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7118 before checking file name handler.
7120 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7121 they've been requested explicitly (bug#9591).
7123 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7125 * keymap.c (Fsingle_key_description): Use make_specified_string
7126 instead of build_string to build string from push_key_description.
7129 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7131 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7132 This fixes a Y2038 bug on 64-bit hosts.
7133 * buffer.c (reset_buffer):
7134 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7135 (Fclear_buffer_auto_save_failure):
7136 Use 0, not -1, to represent an unset failure time, since time_t
7137 might not be signed.
7139 Remove dependency on glibc malloc internals.
7140 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7141 Move back here from lisp.h, but with their new implementations.
7142 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7143 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7144 * charset.c (charset_table_init): New static var.
7145 (syms_of_charset): Use it instead of xmalloc. This removes a
7146 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7147 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7148 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7149 Move back to alloc.c.
7150 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7151 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7153 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7155 * nsterm.m (windowDidResize): Call x_set_window_size only when
7156 ns_in_resize is true. Otherwise set pixelwidth/height and
7157 call change_frame_size (Bug#9628).
7159 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7161 Port --enable-checking=all to Fedora 14 x86-64.
7162 * charset.c (syms_of_charset): Also account for glibc malloc's
7163 internal overhead when calculating the initial malloc maximum.
7165 Port --enable-checking=all to Fedora 14 x86.
7166 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7168 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7169 (overrun_check_realloc, overrun_check_free):
7170 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7171 That way, xmalloc returns a properly-aligned pointer even if
7172 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7173 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7174 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7175 into account when calculating the initial malloc maximum.
7176 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7177 Move here from alloc.c, so that charset.c can use it too.
7178 Properly align; the old code wasn't right for common 32-bit hosts
7179 when configured with --enable-checking=all.
7180 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7181 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7183 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7185 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7188 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7190 * xdisp.c (compute_display_string_end): If there's no display
7191 string at CHARPOS, return -1.
7193 * bidi.c (bidi_fetch_char): When compute_display_string_end
7194 returns a negative value, treat the character as a normal
7195 character not covered by a display string. (Bug#9624)
7197 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7199 * lread.c (Fread_from_string): Fix typo in docstring.
7201 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7203 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7204 newline, reseat the iterator instead of bidi-iterating there one
7205 character at a time. (Bug#9610)
7206 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7207 TO_CHARPOS if the bidi iterator is at base embedding level.
7209 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7211 * lread.c (readevalloop): Use correct code for NBSP.
7212 (read1): Likewise. (Bug#9608)
7214 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7216 * dbusbind.c (Fdbus_register_signal): When service is not
7217 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7219 2011-09-25 Glenn Morris <rgm@gnu.org>
7221 * buffer.c (truncate-lines): Doc fix.
7223 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7225 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7226 (Fset_window_next_buffers): Doc fix.
7228 2011-09-24 Glenn Morris <rgm@gnu.org>
7230 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7232 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7234 Fix minor problems found by static checking.
7235 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7236 * indent.c (Fvertical_motion): Fix == vs = typo.
7238 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7240 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7241 Default value is now t. Doc fix.
7243 * indent.c (Fvertical_motion): Compute and apply the overshoot
7244 logic when moving up, not only when moving down. Fix the
7245 confusing name and values of the it_overshoot_expected variable;
7246 logic changes accordingly. (Bug#9254) (Bug#9549)
7248 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7249 CHARPOS is covered by a display string which includes newlines.
7250 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7251 is covered by a display string with embedded newlines.
7253 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7255 * dbusbind.c (Fdbus_register_signal): Add match rule to
7256 Vdbus_registered_objects_table. (Bug#9581)
7257 (Fdbus_register_method, Vdbus_registered_objects_table):
7260 2011-09-24 Jim Meyering <meyering@redhat.com>
7262 do not ignore write error for any output size
7263 The previous change was incomplete.
7264 While it makes emacs --batch detect the vast majority of stdout
7265 write failures, errors were still ignored whenever the output size is
7266 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7267 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7268 && echo FAIL: ignored write error
7269 FAIL: ignored write error
7270 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7271 && echo FAIL: ignored write error
7272 FAIL: ignored write error
7273 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7275 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7277 * emacs.c (Fkill_emacs): In noninteractive mode exit
7278 non-successfully if a write error occurred on stdout. (Bug#9574)
7280 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7282 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7285 * dispextern.h (struct it): Update the comment documenting what
7288 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7290 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7291 a display string, extend search for cursor position to end of row.
7292 (find_row_edges): If the row ends in a newline from a display
7293 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7294 Handle the case of a display string with multiple newlines.
7295 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7296 non-empty line. Fixes confusing cursor motion with arrow keys at
7297 the beginning of a line that starts with whitespace.
7299 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7301 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7304 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7306 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7309 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7311 * xdisp.c (display_line): Record maximum and minimum buffer
7312 positions even if no glyphs were produced (e.g., by a zero-width
7313 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7314 buffer positions that will be removed from the glyph row because
7316 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7317 column is beyond frame width: don't subtract 1 "pixel" when
7318 computing width of the stretch.
7319 (reseat_at_next_visible_line_start): Undo the change made on
7320 2011-09-17 that saved paragraph information and restored it after
7321 the call to `reseat'. (Bug#9545)
7323 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7325 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7326 and turn window cursor on if cleared (Bug#9415).
7328 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7330 * search.c (boyer_moore): Take unibyte characters from pattern
7331 literally. (Bug#9458)
7333 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7335 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7337 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7339 Fix minor problem found by static checking.
7340 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7341 initialized, to pacify gcc -Wuninitialized.
7343 * fileio.c: Report proper errno when syscall falls.
7344 (Finsert_file_contents): Save and restore errno,
7345 so that report_file_error outputs the correct diagnostic.
7346 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7348 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7350 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7352 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7354 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7355 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7357 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7359 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7360 about the current paragraph and restore it after the call to reseat.
7362 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7363 (bidi_find_paragraph_start): Search back for paragraph beginning
7364 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7365 (bidi_move_to_visually_next): Only trigger paragraph-related
7366 computations when the last character is a newline or at EOB, not
7367 just any NEUTRAL_B. (Bug#9470)
7369 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7370 truncated lines if point is covered by a display string. (Bug#9524)
7372 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7374 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7375 (cons_to_x_long): New function.
7376 (lisp_data_to_selection_data): Use it. Correct the test for
7377 short-versus-long data; it was negated. Break out of vector
7378 loop, for efficiency, when a long datum is discovered.
7380 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7382 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7384 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7386 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7387 GCC PR/17406) by declaring this function with external scope.
7389 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7391 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7392 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7394 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7396 * editfns.c (Fformat): Correctly handle text properties on "%%".

7406 of TAB characters in a composition.
7408 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7410 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7411 This occurs when processing a multibyte format.
7412 Problem reported by Wolfgang Jenker.
7414 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7416 * xdisp.c (try_cursor_movement): Only check for exact match if
7417 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7419 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7421 Remove unused external symbols.
7422 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7423 * xdisp.c (calc_pixel_width_or_height): Now static.
7424 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7425 * indent.c (check_display_width):
7426 * w32term.c: Fix comment to match code.
7427 * xterm.c, xterm.h (x_catching_errors): Remove.
7429 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7431 * xselect.c: Use signed conversions more consistently (Bug#9498).
7432 (selection_data_to_lisp_data): Assume incoming selection data are
7433 signed integers, not unsigned. This is to be consistent with
7434 outgoing selection data, which was modified to use signed integers
7435 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7436 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7437 expects long, not unsigned long.
7439 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7441 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7442 computation of loop end. Reported by Johan Bockgård
7445 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7447 * frame.c (Fother_visible_frames_p): Function deleted.
7449 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7451 * indent.c (compute_motion): Process display vector front to back
7452 rather than the other way around. (Bug#2496)
7454 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7456 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7458 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7460 * minibuf.c (Fread_from_minibuffer): Doc fix.
7462 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7464 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7465 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7467 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7469 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7470 value for non-existent files.
7472 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7474 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7475 set its "size" to -1. This will set the modtime_size field of
7476 the corresponding buffer to -1, which is what
7477 verify-visited-file-modtime expects for files that do not exist.
7480 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7482 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7484 * lisp.h: ... from here. push_key_description is no longer
7485 defined in keyboard.c, so its declaration should not be in
7486 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7487 logically belongs with push_key_description.
7489 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7491 * buffer.h: Include <sys/types.h> instead of <time.h>.
7492 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7493 Problem reported by Herbert J. Skuhra.
7495 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7497 * xml.c (parse_region): Make the parsing work for
7498 non-comment-starting XML files again (bug#9144).
7500 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7502 * image.c (gif_load): Fix calculation of bottom and right corner.
7505 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7507 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7508 redisplay in small windows.
7510 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7512 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7514 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7516 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7517 Operate on live windows only.
7519 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7521 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7523 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7525 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7526 only under bidi iteration.
7528 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7530 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7532 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7534 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7535 Without this fix, the command to link temacs failed due to an
7536 undefined symbol __builtin_isnan. This is because
7537 /usr/include/iso/math_c99.h #defines isnan(x) to
7538 __builtin_isnan(x), but the bundled gcc, which identifies itself
7539 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7541 * floatfns.c (isnan): #undef, and then #define to a clone of
7543 (Fisnan): Always define, since it's always available now.
7544 (syms_of_floatfns): Always define isnan at the Lisp level.
7546 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7548 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7550 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7552 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7553 The previous code assumed that file offsets (off_t values) fit in
7554 EMACS_INT variables, which is not true on typical 32-bit hosts.
7555 The code messed up by falsely reporting buffer overflow in cases
7556 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7557 when "big" contains more than 2**29 bytes, even though this
7558 inserts just one byte and does not overflow the buffer.
7559 (Finsert_file_contents): Store file offsets as off_t
7560 values, not as EMACS_INT values. Check for overflow when
7561 converting between EMACS_INT and off_t. When checking for
7562 buffer overflow or for overlap, take the offsets into account.
7563 Don't use EMACS_INT for small values where int suffices.
7564 When checking for overlap, fix a typo: ZV was used where
7565 ZV_BYTE was intended.
7566 (Fwrite_region): Don't assume off_t fits into 'long'.
7567 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7569 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7571 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7573 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7575 sprintf-related integer and memory overflow issues (Bug#9412).
7577 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7578 (esprintf, exprintf, evxprintf): New functions.
7579 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7580 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7581 (modify_event_symbol): Do not assume that the length of
7582 name_alist_or_stem is safe to alloca and fits in int.
7583 (Fexecute_extended_command): Likewise for function name and binding.
7584 (Frecursion_depth): Wrap around reliably on integer overflow.
7585 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7586 since some callers pass EMACS_INT values.
7587 (Fsingle_key_description): Don't crash if symbol name contains more
7588 than MAX_ALLOCA bytes.
7589 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7590 (get_minibuffer): Arg is now EMACS_INT, not int.
7591 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7592 (esprintf, exprintf, evxprintf): New decls.
7593 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7595 * dbusbind.c (signature_cat): New function.
7596 (xd_signature, Fdbus_register_signal):
7597 Do not overrun buffer; instead, report string overflow.
7599 * dispnew.c (add_window_display_history): Don't overrun buffer.
7600 Truncate instead; this is OK since it's just a log.
7602 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7603 even if the time zone offset is outlandishly large.
7604 Don't mishandle offset == INT_MIN.
7606 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7607 when creating daemon; the previous buffer-overflow check was incorrect.
7609 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7610 which has the guts of the old verror function.
7612 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7613 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7615 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7616 (font_unparse_xlfd): Don't blindly alloca long strings.
7617 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7618 fits in int, when using sprintf. Use single snprintf to count
7619 length of string rather than counting it via multiple sprintfs;
7620 that's simpler and more reliable.
7621 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7622 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7623 sprintf, in case result does not fit in int.
7625 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7626 (fontset_from_font): Print it.
7628 * frame.c (tty_frame_count): Now printmax_t, not int.
7629 (make_terminal_frame, set_term_frame_name): Print it.
7630 (x_report_frame_params): In X, window IDs are unsigned long,
7631 not signed long, so print them as unsigned.
7632 (validate_x_resource_name): Check for implausibly long names,
7633 and don't assume name length fits in 'int'.
7634 (x_get_resource_string): Don't blindly alloca invocation name;
7635 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7638 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7639 (xg_check_special_colors, xg_set_geometry):
7640 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7642 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7643 Use esprintf, not sprintf, in case result does not fit in int.
7645 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7646 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7647 it as a large positive number.
7648 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7649 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7651 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7652 in case result does not fit in int.
7654 * print.c (float_to_string): Detect width overflow more reliably.
7655 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7656 buffer overrun. Don't assume list length fits in 'int'. Treat
7657 print length of 0 as 0, not as infinity; to be consistent with other
7658 uses of print length in this function. Don't overflow print length
7659 index. Don't assume hash table size fits in 'long', or that
7660 vectorlike size fits in 'unsigned long'.
7662 * process.c (make_process): Use printmax_t, not int, to format
7663 process-name gensyms.
7665 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7667 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7668 to avoid potential buffer overrun.
7670 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7671 if X resource line is longer than 512 bytes.
7673 * xfns.c (x_window): Make sprintf buffer a bit bigger
7674 to avoid potential buffer overrun.
7676 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7678 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7680 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7682 Integer overflow fixes for scrolling, etc.
7683 Without these, Emacs silently mishandles large integers sometimes.
7684 For example, "C-u 4294967297 M-x recenter" was treated as if
7685 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7687 * xdisp.c (try_window_id): Check Emacs fixnum range before
7688 converting to 'int'.
7690 * window.c (window_scroll_line_based, Frecenter):
7691 Check that an Emacs fixnum is in range before assigning it to 'int'.
7692 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7693 values converted from Emacs fixnums.
7694 (Frecenter): Don't wrap around a line count if it is out of 'int'
7695 range; instead, treat it as an extreme value.
7696 (Fset_window_configuration, compare_window_configurations):
7697 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7699 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7700 that can exceed INT_MAX. Check that EMACS_INT value is in range
7701 before assigning it to the (possibly-narrower) index.
7702 (match_limit): Don't assume that a fixnum can fit in 'int'.
7704 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7707 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7708 (Fvertical_motion): Don't wrap around LINES values that don't fit
7709 in 'int'. Instead, treat them as extreme values. This is good
7710 enough for windows, which can't have more than INT_MAX lines anyway.
7712 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7714 * Require libxml/parser.h to avoid compilation warning.
7716 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7718 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7719 since this reportedly can destroy thread storage.
7721 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7723 * syntax.c (find_defun_start): Update all cache variables if
7724 exiting early (Bug#9401).
7726 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7728 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7730 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7731 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7732 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7734 * term.c (tty_append_glyph): New function.
7735 (produce_stretch_glyph): Static function and its prototype deleted.
7737 * dispextern.h (produce_stretch_glyph, tty_append_glyph):

7742 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7743 when checking :margin (Bug#9390).
7744 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7745 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7746 so that the name doesn't mislead. All uses changed.
7748 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7750 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7753 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7755 * xdisp.c (move_it_to): Don't bail out early when reaching
7756 position beyond to_charpos, if we are scanning backwards.
7757 (move_it_vertically_backward): When DY == 0, make sure we get to
7758 the first character in the line after the newline.
7760 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7762 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7763 (ccl_driver): Do not generate an out-of-range pointer.
7764 (Fccl_execute_on_string): Remove unnecessary check for
7765 integer overflow, noted by Stefan Monnier in
7766 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7767 Remove a FIXME that didn't need fixing.
7768 Simplify the newly-introduced buffer reallocation code.
7770 2011-08-27 Juanma Barranquero <lekktu@gmail.com>

7774 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7776 Integer and memory overflow issues (Bug#9196).
7778 * doc.c (get_doc_string): Rework so that
7779 get_doc_string_buffer_size is the actual buffer size, rather than
7780 being 1 less than the actual buffer size; this makes xpalloc more
7783 * image.c (x_allocate_bitmap_record, cache_image):
7784 * xselect.c (Fx_register_dnd_atom):
7785 Simplify previous changes by using xpalloc.
7787 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7788 since either will do and ptrdiff_t is convenient with xpalloc.
7790 * charset.c (charset_table_size)
7791 (struct charset_sort_data.priority): Now ptrdiff_t.
7792 (charset_compare): Don't overflow if priorities differ greatly.
7793 (Fsort_charsets): Don't assume list length fits in int.
7794 Check for size-calculation overflow when allocating sort data.
7795 (syms_of_charset): Allocate an initial charset table that is
7796 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7798 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7800 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7801 The actual value is always <= INT_MAX, and leaving it unsigned made
7802 overflow checking harder.
7804 * dispextern.h (struct glyph_matrix.rows_allocated)
7805 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7806 with xpalloc. The values are still always <= INT_MAX.
7808 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7810 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7811 (SAFE_NALLOCA): New macro.

7814 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7815 (set_cache_region, invalidate_region_cache)
7816 (revalidate_region_cache, know_region_cache, region_cache_forward)
7817 (region_cache_backward, pp_cache):
7818 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7819 so that ptrdiff_t * can be passed to xpalloc.
7820 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7821 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7822 (pp_cache): Don't assume cache_len fits in int.
7823 * region-cache.h: Adjust extern decls to match.

7829 (xnmalloc, xnrealloc, xpalloc): New functions.
7831 * bidi.c (bidi_shelve_header_size): New constant.

7833 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7835 * bidi.c (bidi_cache_shrink):
7836 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7838 Don't update size of array until after memory allocation succeeds,
7839 because xmalloc/xrealloc may not return.
7840 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7841 now that we have proper integer overflow checking.
7842 (record_overlay_string, overlay_strings): Catch overflows when
7843 calculating size of overlay_str_buf.
7845 * callproc.c (Fcall_process): Check for size overflow when
7846 calculating size of args2.
7847 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7848 Normally we prefer signed values, but sticking with ptrdiff_t would
7849 require adding more-complicated checks.
7851 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7852 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7853 Redo buffer-overflow calculations to avoid integer overflow.
7854 Add a FIXME comment where memory seems to be over-allocated.
7856 * character.c (Fstring): Check for size-calculation overflow.
7858 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7859 unnecessary integer overflow. Check for size overflow.

7862 * composite.c (get_composition_id): Check for overflow in glyph
7863 length calculations.

7881 (get_doc_string): Check for size calculation overflow.
7882 Don't update size until allocation succeeds.
7883 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7884 EMACS_INT, where ptrdiff_t will do.
7885 (Fsubstitute_command_keys): Check for string overflow.
7887 * editfns.c (set_time_zone_rule): Don't assume environment length
7889 (message_length): Now ptrdiff_t, not int.
7890 (Fmessage_box): Don't update size until allocation succeeds.
7891 Don't assume message length fits in int.
7892 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7894 * emacs.c (main): Do not reallocate argv, since there is a null at
7895 the end that can be overwritten, and this way there's no need to
7896 worry about size-calculation overflow.
7897 (sort_args): Check for size-calculation overflow.
7899 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7901 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7903 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7904 (x_set_scroll_bar_width, x_figure_window_size):
7905 Check for integer overflow.
7906 (x_set_alpha): Do not assume XINT fits in int.
7908 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7909 This is for the members text_lines, text_cols, total_lines, total_cols,
7910 where the system imposes an 'int' limit.
7912 * fringe.c (Fdefine_fringe_bitmap):
7913 Don't update size until alloc works.
7915 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7916 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7918 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7919 Check for size-calculation overflow.
7920 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7921 do, as we prefer signed integers.
7922 (id_to_widget.max_size, id_to_widget.used)
7923 (xg_store_widget_in_map, xg_remove_widget_from_map)
7924 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7925 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7926 Use and return ptrdiff_t, not int.
7927 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7928 * gtkutil.h: Change prototypes to match the above.
7930 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7931 are duplicate now that they've been promoted to lisp.h.
7932 (x_allocate_bitmap_record, x_alloc_image_color)
7933 (make_image_cache, cache_image, xpm_load):

7944 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7945 Use ptrdiff_t, not int, to count maps.

7975 (Fset_match_data): Don't assume list lengths fit in 'int'.
7977 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7978 for command line length. Do not attempt to address one before the

7984 (encode_terminal_code, calculate_costs): Check for size
7985 calculation overflow.

7987 table lengths and related sizes. Don't update size until alloc
7988 done. Redo calculations to avoid overflow.

8009 Check for size calculation overflow.
8010 (cache_face): Treat size calculation overflows as if they were

8013 * xfns.c (x_encode_text, x_set_name_internal)
8014 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8015 sizes, since they can exceed INT_MAX in size. Check for size

8019 (xg_select): Check for size calculation overflow.
8020 Don't update size until alloc done.
8022 * xrdb.c (get_environ_db): Don't assume path length fits in int,

8025 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8026 (X_LONG_MIN): New macros.
8027 Use them to make the following changes clearer.
8028 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

8030 future maintainers not to raise the value too much later.
8031 (SELECTION_QUANTUM): Remove, replacing with ...
8032 (selection_quantum): ... new function, which avoids overflow.
8034 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

8043 Redo calculations to avoid overflow.
8044 (x_reply_selection_request): When sending hint, ceiling it at

8048 (lisp_data_to_selection_data, x_property_data_to_lisp):
8049 Check for size-calculation overflow.

8052 Don't store size until memory allocation succeeds.
8053 (x_get_window_property): Plug memory leak on memory exhaustion.
8054 Don't double-block input; malloc is safe here. Don't assume 2**34
8055 - 4 fits in unsigned long. Add an xassert to check
8056 XGetWindowProperty overflow. Be more careful about overflow
8057 calculations, and distinguish size from memory overflow better.
8058 (receive_incremental_selection): When tracing, don't assume
8059 unsigned int is less than INT_MAX.
8060 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8061 harmful) conversions of unsigned short to int.
8062 (lisp_data_to_selection_data): Don't assume that integers
8063 in the range -65535 through -1 fit in an X unsigned short.
8064 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8065 result parameters unless successful. Rely on cons_to_unsigned
8066 to report problems with elements; the old code wasn't right anyway.
8067 (x_check_property_data): Check for int overflow; we cannot use
8068 a wider type due to X limits.
8069 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8101 * lisp.h (hash_lookup, hash_put):
8102 * minibuf.c (Ftest_completion):
8103 Use ptrdiff_t for hash table indexes, not int (which is too
8104 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8105 32-bit --with-wide-int hosts).
8107 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8108 Add a FIXME comment about memory leaks.

8113 * character.h (CHAR_WIDTH):
8114 * indent.c (MULTIBYTE_BYTES_WIDTH):
8115 Use sanitize_char_width to avoid undefined and/or bad behavior
8116 with outlandish widths.
8117 * character.h (sanitize_tab_width): Rename from sanitize_width,
8118 now that we have two such functions. All uses changed.

8143 (make_lispy_movement): Use same integer type in forward decl
8144 that is used in the definition.
8145 (read_key_sequence, keyremap_step):
8146 Change bufsize argument back to int, undoing my 2011-03-30 change.
8147 We prefer signed types, and int is wide enough here.
8148 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8149 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8150 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8151 length, not size_t. Use ptrdiff_t for index, not int.
8152 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8153 possibility of integer overflow.
8155 Overflow, signedness and related fixes for images.

8165 * xdisp.c (calc_pixel_width_or_height):
8166 * xfns.c (image_cache_refcount):

8168 on typical 64-bit hosts.
8170 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8171 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8179 since parse_image_check makes sure they fit into int.
8180 (png_load, gif_load, svg_load_image):
8181 Prefer int to unsigned where either will do.
8182 (tiff_handler): New function, combining the cores of the
8183 old tiff_error_handler and tiff_warning_handler.
8184 This function is rewritten to use vsnprintf and thereby avoid
8185 stack buffer overflows. It uses only the features of vsnprintf
8186 that are common to both POSIX and native Microsoft.
8187 (tiff_error_handler, tiff_warning_handler): Use it.
8188 (tiff_load, gif_load, imagemagick_load_image):
8189 Don't assume :index value fits in 'int'.
8190 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

8192 the integer types that MagickCropImage accepts. Don't assume
8193 Vimagemagick_render_type has a nonnegative value. Don't assume
8194 size_t fits in 'long'.
8195 (gs_load): Use printmax_t to print the widest integers possible.

8208 handle_single_display_spec, not just 1 or zero.
8209 (handle_single_display_spec): If the display spec is of the form
8210 `(space ...)', and specifies display in the text area, return 2
8212 (try_cursor_movement): Check for the need to scroll more
8213 accurately, and prefer exact match for point under bidi.
8214 Don't advance `row' beyond the last row of the window.

8235 positioning on the newline at EOL of R2L text within L2R
8236 paragraph, and vice versa.
8237 (try_cursor_movement): Check continued rows, in addition to
8238 continuation rows. Fixes unwarranted scroll when point enters a
8239 continued line of R2L text within an L2R paragraph, or vice versa.

8241 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8242 from the end of a short line to the beginning of a continued line
8243 of R2L text within L2R paragraph.
8244 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

8263 extra slot even if the purpose is char-code-property-table.
8265 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8267 * xdisp.c (redisplay_window): When computing centering_position,
8268 account for the height of the header line. (Bug#8874)
8270 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8271 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8272 candidate is selected by the mouse, and that candidate has a
8273 composed character under the mouse.
8275 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8276 coordinates reported by pos-visible-in-window-p for a composed
8277 character in column zero.

8287 composed buffer positions.
8289 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8291 * image.c (gif_load): Don't assume that each subimage has the same
8292 dimensions as the base image. Handle disposal method that is
8293 "undefined" by the gif spec (Bug#9335).
8295 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

8302 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8303 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8304 from an Org mode buffer to a Speedbar frame.
8306 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8307 a composition, take its buffer position from IT->cmp_it.charpos.
8308 Fixes cursor positioning at the beginning of a line that begins
8309 with a composed character.
8311 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8313 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8314 character bidirectional type, use STRONG_L instead. Fixes crashes
8315 in a buffer produced by `describe-categories'.
8317 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8318 members before the level stack, so they would be saved and
8319 restored when copying iterator state. Fixes incorrect reordering
8320 around TABs covered by display properties.
8322 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

8455 buffer/string position, to be restored by pop_it. Fix flags in
8456 the iterator structure wrt the object coming from a display
8457 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8458 properties. (Bug#9284)

8678 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8679 In other words, assume that every image size is allowed, on non-X
8680 hosts. This assumption is probably wrong, but it lets Emacs compile.
8682 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8684 * regex.c (re_iswctype): Convert return values to boolean.
8686 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8688 * xdisp.c (compute_display_string_pos): Don't use cached display
8689 string position if the buffer had its restriction changed.
8692 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8694 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8696 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8698 Integer signedness and overflow and related fixes. (Bug#9079)
8700 * bidi.c: Integer size and overflow fixes.
8701 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8702 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8703 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8704 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8705 (bidi_find_other_level_edge):
8706 Use ptrdiff_t instead of EMACS_INT where either will do.
8707 This works better on 32-bit hosts configured --with-wide-int.
8708 (bidi_cache_ensure_space): Check for size-calculation overflow.
8709 Use % rather than repeated addition, for better worst-case speed.
8710 Don't set bidi_cache_size until after xrealloc returns, because it
8712 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8713 (bidi_cache_ensure_space): Also check that the bidi cache size
8714 does not exceed that of the largest Lisp string or buffer. See Eli
8715 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8717 * alloc.c (__malloc_size_t): Remove.
8718 All uses replaced by size_t. See Andreas Schwab's note
8719 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8721 * image.c: Improve checking for integer overflow.
8722 (check_image_size): Assume that f is nonnull, since
8723 it is always nonnull in practice. This is one less thing to
8724 worry about when checking for integer overflow later.
8725 (x_check_image_size): New function, which checks for integer
8726 overflow issues inside X.
8727 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8728 This removes the need for a memory_full check.
8729 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8730 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8731 (xbm_read_bitmap_data): Change locals back to 'int', since
8732 their values must fit in 'int'.
8733 (xpm_load_image, png_load, tiff_load):
8734 Invoke x_create_x_image_and_pixmap earlier,
8735 to avoid much needless work if the image is too large.
8736 (tiff_load): Treat overly large images as if
8737 x_create_x_image_and_pixmap failed, not as malloc failures.
8738 (gs_load): Use x_check_image_size.
8740 * gtkutil.c: Omit integer casts.
8741 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8742 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8744 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8746 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8747 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8748 would wrongly return t on a 64-bit host.
8750 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8751 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8752 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8753 and therefore cause GCC to emit a bogus diagnostic in some cases.
8755 * image.c: Integer signedness and overflow and related fixes.
8756 This is not an exhaustive set of fixes, but it's time to
8757 record what I've got.
8758 (lookup_pixel_color, check_image_size): Remove redundant decls.
8759 (check_image_size): Don't assume that arbitrary EMACS_INT values
8760 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8761 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8762 (tiff_load, imagemagick_load_image):
8763 Check for overflow in size calculations.
8764 (x_create_x_image_and_pixmap): Remove unnecessary test for
8765 xmalloc returning NULL; that can't happen.
8766 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8767 (xpm_color_bucket): Use better integer hashing function.
8768 (xpm_cache_color): Don't possibly over-allocate memory.
8769 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8770 (gif_memory_source):
8771 Use ptrdiff_t, not int or size_t, to record sizes.
8772 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8773 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8774 either works, as we prefer signed integers.
8775 (tiff_read_from_memory, tiff_write_from_memory):
8776 Return tsize_t, not size_t, since that's what the TIFF API wants.
8777 (tiff_read_from_memory): Don't fail simply because the read would
8778 go past EOF; instead, return a short read.
8779 (tiff_load): Omit no-longer-needed casts.
8780 (Fimagemagick_types): Don't assume size fits into 'int'.
8782 Improve hashing quality when configured --with-wide-int.
8783 * fns.c (hash_string): New function, taken from sxhash_string.
8784 Do not discard information about ASCII character case; this
8785 discarding is no longer needed.
8786 (sxhash-string): Use it. Change sig to match it. Caller changed.
8787 * lisp.h: Declare it.
8788 * lread.c (hash_string): Remove, since we now use fns.c's version.
8789 The fns.c version returns a wider integer if --with-wide-int is
8790 specified, so this should help the quality of the hashing a bit.
8792 * emacs.c: Integer overflow minor fix.
8793 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8794 Define only if GNU_LINUX.
8795 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8797 * dispnew.c: Integer signedness and overflow fixes.
8798 Remove unnecessary forward decls, that were a maintenance hassle.
8799 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8801 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8802 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8803 (prepare_desired_row, line_draw_cost):
8804 Use int, not unsigned, where either works.
8805 (save_current_matrix, restore_current_matrix):
8806 Use ptrdiff_t, not size_t, where either works.
8807 (init_display): Check for overflow more accurately, and without
8808 relying on undefined behavior.
8810 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8811 Remove, replacing with the new symbols in lisp.h. All uses changed.
8812 * fileio.c (make_temp_name):
8813 * filelock.c (lock_file_1, lock_file):
8814 * xdisp.c (message_dolog):
8815 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8816 Use pMd etc. instead.
8817 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8818 replacing the pWIDE etc. symbols removed from editfns.c.
8820 * keyboard.h (num_input_events): Now uintmax_t.
8821 This is (very slightly) less likely to mess up due to wraparound.
8824 * buffer.c: Integer signedness fixes.
8825 (alloc_buffer_text, enlarge_buffer_text):
8826 Use ptrdiff_t rather than size_t when either will do, as we prefer
8829 * alloc.c: Integer signedness and overflow fixes.
8830 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8831 (__malloc_size_t): Default to size_t, not to int.
8832 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8833 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8834 Prefer ptrdiff_t to size_t when either would do, as we prefer
8836 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8837 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8838 Now const. Initialize with values that are in range even if char
8840 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8841 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8842 These functions do the right thing with sizes > 2**32.
8843 (check_depth): Now ptrdiff_t, not int.
8844 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8845 Adjust to new way of storing sizes. Check for size overflow bugs
8847 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8848 slightly wrong anyway, as it missed one instance of
8849 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8850 (refill_memory_reserve): Omit needless cast to size_t.
8851 (mark_object_loop_halt): Mark as externally visible.
8853 * xselect.c: Integer signedness and overflow fixes.
8854 (Fx_register_dnd_atom, x_handle_dnd_message):
8855 Use ptrdiff_t, not size_t, since we prefer signed.
8856 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8857 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8858 x_dnd_atoms_size and x_dnd_atoms_length.
8860 * doprnt.c: Prefer signed to unsigned when either works.
8862 * doprnt.c (doprnt):
8864 * xdisp.c (vmessage):
8865 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8866 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8867 prefer signed arithmetic to avoid comparison confusion.
8868 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8869 but is a bit tricky.
8871 Assume freestanding C89 headers, string.h, stdlib.h.
8872 * data.c, doprnt.c, floatfns.c, print.c:
8873 Include float.h unconditionally.
8874 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8875 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8876 * regex.c: Likewise for stddef.h, string.h.
8877 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8878 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8879 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8880 (STDC_HEADERS): Remove obsolete defines.
8881 * sysdep.c: Include limits.h unconditionally.
8883 Assume support for memcmp, memcpy, memmove, memset.
8884 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8885 * regex.c (memcmp, memcpy):
8886 Remove; we assume C89 now.
8888 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8889 (__malloc_safe_bcopy): Remove; no longer needed.
8891 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8892 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8893 well either way, and we prefer signed to unsigned.
8895 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8897 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8898 closes the connection while we're reading (bug#9182).
8900 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8902 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8903 are specified (Bug#9168).
8905 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8907 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8908 Found by GCC static checking and --with-wide-int on a 32-bit host.
8910 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8912 * xdisp.c (compute_display_string_pos): Fix logic of caching
8913 previous display string position. Initialize cached_prev_pos to
8914 -1. Fixes slow-down at the beginning of a buffer.
8916 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8918 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8919 for attrs[LFACE_FONTSET_INDEX].
8921 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8923 * xml.c (parse_region): Remove unused local
8924 that was recently introduced.
8926 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8928 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8929 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8931 * xdisp.c (move_it_in_display_line_to): Record the best matching
8932 position for TO_CHARPOS while scanning the line, and restore it on
8933 exit if none of the characters scanned was an exact match.
8934 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8935 when exact match is impossible due to invisible text, and the
8936 lines are truncated.
8938 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8940 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8943 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8945 Fix a significant slow-down of cursor motion with C-n, C-p,
8946 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8947 auto-repeat under bidi redisplay in fontified buffers.
8948 * xdisp.c (compute_stop_pos_backwards): New function.
8949 (next_element_from_buffer): Call compute_stop_pos_backwards to
8950 find a suitable prev_stop when we find ourselves before
8952 (reseat): Don't look for prev_stop, as that could mean a very long
8954 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8955 <cached_disp_overlay_modiff>: Cache for last found display string
8957 (compute_display_string_pos): Return the cached position if asked
8958 about the same buffer in the same area of character positions, and
8959 the buffer wasn't changed since the time the display string
8960 position was cached.
8962 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8964 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8965 is an integer, which is important for empty lines. (Bug#9149)
8967 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8969 * frame.c (Fmodify_frame_parameters): In tty case, update the
8970 default face if necessary (Bug#4238).
8972 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8974 * editfns.c (Fstring_to_char): No need to explain what a character
8975 is in the docstring (Bug#6576).
8977 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8979 * xml.c (parse_region): Make sure we always return a tree.
8981 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8983 * xml.c (parse_region): If a document contains only comments,
8986 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8988 * xml.c (make_dom): Return comments, too.
8990 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8993 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8994 and the surrounding thread.
8995 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8996 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8997 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8999 * s/openbsd.h (BROKEN_SIGIO): Define.
9000 * unexelf.c (unexec) [__OpenBSD__]:
9001 Don't update the .mdebug section of the Alpha COFF symbol table.
9003 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9005 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9008 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9010 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9011 This fixes some race conditions on the permissions of any newly
9014 * alloc.c (valid_pointer_p): Use pipe, not open.
9015 This fixes some permissions issues when debugging.
9017 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9018 If fchown fails to set both uid and gid, try to set just gid,
9019 as that is sometimes allowed. Adjust the file's mode to eliminate
9020 setuid or setgid bits that are inappropriate if fchown fails.
9022 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9024 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9025 to compare Lisp_Objects.
9026 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9027 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9028 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9030 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9032 * lread.c (read_integer): Unread even EOF character.
9033 (read1): Likewise. Properly record start position of symbol.
9035 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9036 symbol character follows.
9038 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9040 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9041 This works around a problem with the previous change to Fcopy_file.
9042 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9043 and without this change, GCC might complain about discarding
9044 fchown's return value.
9046 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9048 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9050 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9052 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9054 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9056 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9057 it's used from the C level.
9059 * process.c: Use the same condition for POLL_FOR_INPUT in both
9060 keyboard.c and process.c (bug#1858).
9062 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9064 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9065 (Fgnutls_boot): Use it.
9067 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9069 * doc.c (Fsubstitute_command_keys): Revert last change.
9071 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9073 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9074 quotes the next character, and doesn't affect other longer
9075 sequences (bug#8935).
9077 * lread.c (syms_of_lread): Clarify that is isn't only
9078 `eval-buffer' and `eval-defun' that's affected by
9079 `lexical-binding' (bug#8460).
9081 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9083 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9084 bidi redisplay when a line includes both an image and is truncated.
9086 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9088 Fix minor problems found by static checking.
9089 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9090 (elsz): Now a signed constant, not a size_t var. We prefer signed
9091 types to unsigned, to avoid integer comparison confusion. Without
9092 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9093 "cannot optimize loop, the loop counter may overflow", a symptom
9095 * indent.c (Fvertical_motion): Mark locals as initialized.
9096 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9098 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9100 * search.c (Fre_search_backward): Mention `case-fold-search' in
9101 all the re_search_* functions (bug#8138).
9103 * keyboard.c (Fopen_dribble_file): Document when the file is
9106 2011-07-14 Eli Zaretskii <eliz@gnu.org>
9108 * bidi.c (bidi_dump_cached_states): Fix format of displaying
9111 Support bidi reordering of display and overlay strings.
9112 * xdisp.c (compute_display_string_pos)
9113 (compute_display_string_end): Accept additional argument STRING.
9114 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
9115 (reseat_to_string): Initialize bidi_it->string.s and
9116 bidi_it->string.schars.
9117 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
9118 NULL (avoids a crash in bidi_paragraph_init).
9119 Initialize itb.string.lstring.
9120 (init_iterator): Call bidi_init_it only of a valid
9121 buffer position was specified. Initialize paragraph_embedding to
9123 (reseat_to_string): Initialize the bidi iterator.
9124 (display_string): If we need to ignore text properties of
9125 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9126 original value of -1 will not work with bidi.)
9127 (compute_display_string_pos): First arg is now struct
9128 `text_pos *'; all callers changed. Support display properties on
9130 (compute_display_string_end): Support display properties on Lisp
9132 (init_iterator, reseat_1, reseat_to_string): Initialize the
9133 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9134 when iterating on a string not from display properties).
9135 (compute_display_string_pos, compute_display_string_end):

9620 (clone_per_buffer_values): Don't assume that

9661 Random fixes. E.g., (random) never returned negative values.
9662 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9663 subseconds part to the entropy, as that's a bit more random.
9664 Prefer signed to unsigned, since the signedness doesn't matter and
9665 in general we prefer signed. When given a limit, use a
9666 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9667 latter isn't right if USE_2_TAGS_FOR_INTS.
9668 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9669 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9681 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9682 This is more efficient than Ffile_directory_p and avoids a minor race.
9684 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9686 * buffer.c (Foverlay_put): Say what the return value is
9689 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9690 is a directory before asking whether to use the file name
9692 (barf_or_query_if_file_exists): Make the "File is a directory"
9693 error be more correct.
9695 * fns.c (Frequire): Remove the mention of the .gz files, since
9696 that's installation-specific, but keep the mention of
9697 `get-load-suffixes'.
9699 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9701 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9712 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

9776 (syms_of_keymap): Defsubr make-composed-keymap.
9777 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

9814 * eval.c (struct backtrace): Simplify and port the data structure.
9815 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9816 signed bit field, as this assumption is not portable and it makes
9817 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9818 "char debug_on_exit : 1" as this is not portable either; instead,
9819 use the portable "unsigned int debug_on_exit : 1". Remove unused
9820 member evalargs. Remove obsolete comments about cc bombing out.

10048 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10049 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10050 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10051 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10052 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10054 (debug_method_add): Use va_list and vsprintf rather than relying
10055 on undefined behavior with wrong number of arguments.
10056 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10057 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10058 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10059 since we're not interested in debugging glyphs with old libraries.
10060 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10061 GCC 4.6.0's static checking.
10063 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10065 Integer overflow and signedness fixes (Bug#8873).
10066 A few related buffer overrun fixes, too.
10068 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
10070 * dispextern.h (struct face.stipple):
10071 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)

10073 (x_create_bitmap_from_data, x_create_bitmap_from_file)
10074 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10075 (x_create_bitmap_from_xpm_data):
10076 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10077 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10079 * xfaces.c (load_pixmap):
10080 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10081 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10082 (.bitmaps_last, struct x_output.icon_bitmap):
10083 Use ptrdiff_t, not int, for bitmap indexes.
10084 (x_allocate_bitmap_record): Check for size overflow.
10085 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10087 Use ptrdiff_t, not int, for overlay counts.
10088 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10089 * editfns.c (overlays_around, get_pos_property):
10090 * textprop.c (get_char_property_and_overlay):
10091 * xdisp.c (next_overlay_change, note_mouse_highlight):
10092 * xfaces.c (face_at_buffer_position):
10093 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10094 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10095 (Fnext_overlay_change, Fprevious_overlay_change)
10096 (mouse_face_overlay_overlaps, Foverlays_in):
10097 Use ptrdiff_t, not int, for sizes.
10098 (overlays_at, overlays_in): Check for size-calculation overflow.
10100 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10102 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10103 (x_session_initialize): Do not assume string length fits in int.
10105 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10106 This is unlikely, but can occur if DPI is outlandish.
10108 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10109 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10111 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10112 * xrdb.c (magic_file_p, search_magic_path):
10113 Omit last arg SUFFIX; it was always 0. All callers changed.
10114 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10116 * xfont.c (xfont_match): Avoid need for strlen.
10118 * xfns.c: Don't assume strlen fits in int.
10119 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10121 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10122 not unsigned long, as we prefer signed integers. All callers changed.
10123 Detect integer overflow in repeat count.
10124 (message_dolog): Don't assume print length fits in 39 bytes.
10125 (display_mode_element): Don't assume strlen fits in int.
10127 * termcap.c: Don't assume sizes fit in int and never overflow.
10128 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10129 (gobble_line): Check for size-calculation overflow.
10131 * minibuf.c (Fread_buffer):
10132 * lread.c (intern, intern_c_string):
10133 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10134 Don't assume string length fits in int.
10136 * keyboard.c (parse_tool_bar_item):
10137 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10139 * font.c: Don't assume string length fits in int.
10140 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10141 Use ptrdiff_t, not int.
10142 (font_intern_prop): Don't assume string length fits in int.
10143 Don't assume integer property fits in fixnum.
10144 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10146 * filelock.c: Fix some buffer overrun and integer overflow issues.
10147 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10148 Reformulate so as not to need the command string.
10149 Invoke gzip -cd rather than gunzip, as it's more portable.
10150 (lock_info_type, lock_file_1, lock_file):
10151 Don't assume pid_t and time_t fit in unsigned long.
10152 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10153 (current_lock_owner): Prefer signed type for sizes.
10154 Use memcpy, not strncpy, where memcpy is what is really wanted.
10155 Don't assume (via atoi) that time_t and pid_t fit in int.
10156 Check for time_t and/or pid_t out of range, e.g., via a network share.
10157 Don't alloca where an auto var works fine.
10159 * fileio.c: Fix some integer overflow issues.
10160 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10161 Don't assume string length fits in int.
10162 (directory_file_name): Don't assume string length fits in long.
10163 (make_temp_name): Don't assume pid fits in int, or that its print
10164 length is less than 20.
10166 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10168 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10170 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10172 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10173 We prefer signed integers, even for size calculations.
10175 * emacs.c: Don't assume string length fits in 'int'.
10176 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10177 (main): Don't invoke strlen when not needed.
10179 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10180 (XD_DEBUG_MESSAGE): Don't waste a byte.
10182 * callproc.c (getenv_internal_1, getenv_internal)
10183 (Fgetenv_internal):
10184 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10186 * lread.c (invalid_syntax): Omit length argument.
10187 All uses changed. This doesn't fix a bug, but it simplifies the
10188 code away from its former Hollerith-constant appearance, and it's
10189 one less 'int' to worry about when looking at integer-overflow issues.
10190 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10192 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10193 This didn't break anything, but it didn't help either.
10194 It's confusing to put a bogus integer in a place where the actual
10195 value does not matter.
10196 (LIST_END_P): Remove unused macro and its bogus comment.
10197 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10199 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10200 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10202 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10203 We prefer signed types, and the value cannot exceed the EMACS_INT
10204 range anyway (because otherwise the length would not be representable).
10205 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10206 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10207 This avoids a GCC warning when WIDE_EMACS_INT.
10209 * indent.c (sane_tab_width): New function.
10210 (current_column, scan_for_column, Findent_to, position_indentation)
10211 (compute_motion): Use it. This is just for clarity.
10212 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10214 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10216 * lisp.h (lint_assume): New macro.
10217 * composite.c (composition_gstring_put_cache):
10218 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10220 * editfns.c, insdel.c:
10221 Omit unnecessary forward decls, to simplify future changes.
10223 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10225 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10227 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10228 Use much-faster test for byte-length change.
10229 Don't assume string byte-length fits in 'int'.
10230 Check that character arg fits in 'int'.
10231 (mapcar1): Declare byte as byte, for clarity.
10233 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10235 * fns.c (concat): Catch string overflow earlier.
10236 Do not rely on integer wraparound.
10238 * dispextern.h (struct it.overlay_strings_charpos)
10239 (struct it.selective): Now EMACS_INT, not int.
10240 * xdisp.c (forward_to_next_line_start)
10241 (back_to_previous_visible_line_start)
10242 (reseat_at_next_visible_line_start, next_element_from_buffer):
10243 Don't arbitrarily truncate the value of 'selective' to int.
10245 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10247 * composite.c: Don't truncate sizes to 'int'.
10248 (composition_gstring_p, composition_reseat_it)
10249 (composition_adjust_point): Use EMACS_INT, not int.
10250 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10251 not EMACS_UINT, for indexes.
10253 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10255 * buffer.c: Include <verify.h>.
10256 (struct sortvec.priority, struct sortstr.priority):
10257 Now EMACS_INT, not int.
10258 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10259 (struct sortstr.size, record_overlay_string)
10260 (struct sortstrlist.size, struct sortlist.used):
10261 Don't truncate size to int.
10262 (record_overlay_string): Check for size-calculation overflow.
10263 (init_buffer_once): Check at compile-time, not run-time.
10265 2011-06-22 Jim Meyering <meyering@redhat.com>
10267 Don't leak an XBM-image-sized buffer
10268 * image.c (xbm_load): Free the image buffer after using it.
10270 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10273 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10274 that Sun C diagnosed.
10275 * fns.c (secure_hash): Fix pointer signedness issue.
10276 * intervals.c (static_offset_intervals): New function.
10277 (offset_intervals): Use it.
10279 2011-06-21 Leo Liu <sdl.web@gmail.com>
10282 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10285 * fns.c (secure_hash): Rename from crypto_hash_function and change
10286 the first arg to accept symbols.
10287 (Fsecure_hash): New primitive.
10288 (syms_of_fns): New symbols.
10290 2011-06-20 Deniz Dogan <deniz@dogan.se>
10292 * process.c (Fset_process_buffer): Clarify return value in
10295 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10297 * dispnew.c (add_window_display_history): Use BVAR.
10299 * xdisp.c (debug_method_add): Use BVAR.
10300 (check_window_end, dump_glyph_matrix, dump_glyph)
10301 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10303 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10306 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10307 check till after the cache is created in init_frame_faces.
10309 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10311 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10313 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10315 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10316 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10317 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10319 Improve buffer-overflow checking (Bug#8873).
10320 * fileio.c (Finsert_file_contents):
10321 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10322 Remove the old (too-loose) buffer overflow checks.
10323 They weren't needed, since make_gap checks for buffer overflow.
10324 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10325 The old code merely checked for Emacs fixnum overflow, and relied
10326 on undefined (wraparound) behavior. The new code avoids undefined
10327 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10329 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10330 Tune. Don't use wider integers than needed. Don't use alloca.
10331 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10333 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10335 * insdel.c, lisp.h (buffer_overflow): New function.
10336 (insert_from_buffer_1, replace_range, replace_range_2):
10337 * insdel.c (make_gap_larger):
10338 * editfns.c (Finsert_char):
10339 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10341 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10343 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10345 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10347 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10348 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10350 * fileio.c: Don't assume EMACS_INT fits in off_t.
10351 (emacs_lseek): New static function.
10352 (Finsert_file_contents, Fwrite_region): Use it.
10353 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10355 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10357 * fns.c: Don't overflow int when computing a list length.
10358 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10359 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10360 truncation on 64-bit hosts. Check for QUIT every
10361 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10362 faster and is responsive enough.
10363 (Flength): Report an error instead of overflowing an integer.
10364 (Fsafe_length): Return a float if the value is not representable
10365 as a fixnum. This shouldn't happen except in contrived situations.
10366 (Fnthcdr, Fsort): Don't assume list length fits in int.
10367 (Fcopy_sequence): Don't assume vector length fits in int.
10369 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10370 (header_size, word_size): New constants.
10371 (allocate_vectorlike): Don't check size overflow here.
10372 (allocate_vector): Check it here instead, since this is the only
10373 caller of allocate_vectorlike that could cause overflow.
10374 Check that the new vector's length is representable as a fixnum.
10376 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10377 The previous code was bogus. For example, next_almost_prime (32)
10378 returned 39, which is undesirable as it is a multiple of 3; and
10379 next_almost_prime (24) returned 25, which is a multiple of 5 so
10380 why was the code bothering to check for multiples of 7?
10382 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10384 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10386 Variadic C functions now count arguments with ptrdiff_t.
10387 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10388 Back then I didn't know that the Emacs coding style prefers signed int.
10389 Also, in the meantime I found a few more instances where arguments
10390 were being counted with int, which may truncate counts on 64-bit
10391 machines, or EMACS_INT, which may be unnecessarily wide.
10392 * lisp.h (struct Lisp_Subr.function.aMANY)
10393 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10394 Arg counts are now ptrdiff_t, not size_t.
10395 All variadic functions and their callers changed accordingly.
10396 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10397 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10398 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10399 * callint.c (Fcall_interactively): Check arg count for overflow,
10400 to avoid potential buffer overrun. Use signed char, not 'int',
10401 for 'varies' array, so that we needn't bother to check its size
10402 calculation for overflow.
10403 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10404 * eval.c (apply_lambda):
10405 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10406 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10407 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10409 * callint.c (Fcall_interactively): Don't use index var as event count.
10411 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10412 * mem-limits.h (SIZE): Remove; no longer used.
10414 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10416 Remove unnecessary casts.
10417 * xterm.c (x_term_init):
10418 * xfns.c (x_set_border_pixel):
10419 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10420 These aren't needed now that we assume ANSI C.
10422 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10423 It's more likely to cause problems (due to unsigned overflow)
10426 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10428 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10430 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10432 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10434 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10436 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10438 GLYPH_CODE_FACE returns EMACS_INT, not int.
10439 * dispextern.h (merge_faces):
10440 * xfaces.c (merge_faces):
10441 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10442 Don't assume EMACS_INT fits in int.
10444 * character.h (CHAR_VALID_P): Remove unused parameter.
10445 * fontset.c, lisp.h, xdisp.c: All uses changed.
10447 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10449 * fns.c (concat): Minor tuning based on overflow analysis.
10450 This doesn't fix any bugs. Use int to hold character, instead
10451 of constantly refetching from Emacs object. Use XFASTINT, not
10452 XINT, for value known to be a character. Don't bother comparing
10453 a single byte to 0400, as it's always less.
10455 * floatfns.c (Fexpt):
10456 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10458 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10461 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10463 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10464 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10465 incorrectly succeed when S was a string, because 4294967386 was
10466 truncated before it was used.
10468 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10469 Otherwise, an out-of-range integer could cause undefined behavior
10472 * composite.c: Use int, not EMACS_INT, for characters.
10473 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10474 EMACS_INT, for values that are known to be in character range.
10475 This doesn't fix any bugs but is the usual style inside Emacs and
10476 may generate better code on 32-bit machines.
10478 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10479 This is for reasons similar to the recent CHAR_STRING fix.
10480 * charset.c (Fencode_char): Check that character arg is actually
10481 a character. Pass an int to ENCODE_CHAR.
10482 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10483 wider than 'int', as a compile-time check to prevent future regressions
10486 * character.c (char_string): Remove unnecessary casts.
10488 Make sure a 64-bit char is never passed to CHAR_STRING.
10489 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10490 by silently ignoring the top 32 bits, allowing some values
10491 that were far too large to be valid characters.
10492 * character.h: Include <verify.h>.
10493 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10494 arguments are no wider than unsigned, as a compile-time check
10495 to prevent future regressions in this area.
10497 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10498 (Fsubst_char_in_region):
10500 * xdisp.c (decode_mode_spec_coding):
10501 Adjust to CHAR_STRING's new requirement.
10502 * editfns.c (Finsert_char, Fsubst_char_in_region):
10503 * fns.c (concat): Check that character args are actually
10504 characters. Without this test, these functions did the wrong
10505 thing with wildly out-of-range values on 64-bit hosts.
10507 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10508 These casts should not be needed on 32-bit hosts, either.
10509 * keyboard.c (read_char):
10510 * lread.c (Fload): Remove casts to unsigned.
10512 * lisp.h (UNSIGNED_CMP): New macro.
10513 This fixes comparison bugs on 64-bit hosts.
10514 (ASCII_CHAR_P): Use it.
10515 * casefiddle.c (casify_object):
10516 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10517 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10518 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10519 * dispextern.h (FACE_FROM_ID):
10520 * keyboard.c (read_char): Use UNSIGNED_CMP.
10522 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10523 not to EMACS_INT, to avoid GCC warning.
10525 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10527 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10528 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10529 isn't needed on 32-bit machines.
10531 * buffer.c (Fgenerate_new_buffer_name):
10532 Use EMACS_INT for count, not int.
10533 (advance_to_char_boundary): Return EMACS_INT, not int.
10535 * data.c (Qcompiled_function): Now static.
10537 * window.c (window_body_lines): Now static.
10539 * image.c (gif_load): Rename local to avoid shadowing.
10541 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10542 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10543 * alloc.c (make_save_value): Integer argument is now of type
10544 ptrdiff_t, not int.
10545 (mark_object): Use ptrdiff_t, not int.
10546 * lisp.h (pD): New macro.
10547 * print.c (print_object): Use it.
10549 * alloc.c: Use EMACS_INT, not int, to count objects.
10550 (total_conses, total_markers, total_symbols, total_vector_size)
10551 (total_free_conses, total_free_markers, total_free_symbols)
10552 (total_free_floats, total_floats, total_free_intervals)
10553 (total_intervals, total_strings, total_free_strings):
10554 Now EMACS_INT, not int. All uses changed.
10555 (Fgarbage_collect): Compute overall total using a double, so that
10556 integer overflow is less likely to be a problem. Check for overflow
10557 when converting back to an integer.
10558 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10559 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10560 These were 'int' variables that could overflow on 64-bit hosts;
10561 they were never used, so remove them instead of repairing them.
10562 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10563 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10564 Previously, this ceilinged at INT_MAX, but that doesn't work on
10566 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10568 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10569 (allocate_vectorlike): Check for ptrdiff_t overflow.
10570 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10571 when a (possibly-narrower) signed value would do just as well.
10572 We prefer using signed arithmetic, to avoid comparison confusion.
10574 * alloc.c: Catch some string size overflows that we were missing.
10575 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10576 for convenience in STRING_BYTES_MAX.
10577 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10578 The definition here is exact; the one in lisp.h was approximate.
10579 (allocate_string_data): Check for string overflow. This catches
10580 some instances we weren't catching before. Also, it catches
10581 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10582 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10583 and ptrdiff_t and EMACS_INT are both 64 bits.
10585 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10586 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10587 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10589 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10591 * alloc.c (Fmake_string): Check for out-of-range init.
10593 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10595 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.

10617 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10619 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

10626 * window.c (temp_output_buffer_show): Call display_buffer with
10627 second argument Vtemp_buffer_show_specifiers and reset latter
10628 immediately after the call.
10629 (Vtemp_buffer_show_specifiers): New variable.
10630 (auto_window_vscroll_p, next_screen_context_lines)
10631 (Vscroll_preserve_screen_position): Remove leading asterisks from

11174 (bidi_level_of_next_char): Don't try to lookup the cache for the
11175 next/previous character if nothing is cached there yet, or if we
11176 were just reseat()'ed to a new position.
11178 * xdisp.c (set_cursor_from_row): Set start and stop points
11179 according to the row's direction when priming the loop that looks
11180 for the glyph on which to display cursor.

11182 (display_prop_intangible_p): Reimplement to call
11183 handle_display_spec instead of single_display_spec_intangible_p.

11194 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11195 value of a `display' property is a "replacing spec".
11196 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11197 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11198 the display property, but just return a value indicating whether
11199 the display property will replace the characters it covers.
11200 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11201 frame_window_p members of struct bidi_it.
11202 (compute_display_string_pos, compute_display_string_end):

11227 * gnutls.c: Use Emacs's memory allocators.
11228 Without this change, the gnutls library would invoke malloc etc.
11229 directly, which causes problems on non-SYNC_INPUT hosts, and which
11230 runs afoul of improving memory_full behavior. (Bug#8761)
11231 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11232 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11233 xfree instead of the default malloc, realloc, free.
11234 (Fgnutls_boot): No need to check for memory allocation failure,
11235 since xmalloc does that for us.

11264 need to be updated by these changes.
11265 * fns.c (make_hash_table, maybe_resize_hash_table):
11266 Check for integer overflow with large hash tables.
11267 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11268 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11269 (SXHASH_REDUCE): New macro.
11270 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11271 Use it instead of discarding useful hash info with large hash values.
11272 (sxhash_float): New function.
11273 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11274 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11275 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11276 Rewrite to use FIXNUM_BITS, as this simplifies things.
11277 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11278 Adjust signatures to match updated version of code.
11279 (consing_since_gc): Now EMACS_INT, since a single hash table can
11280 use more than INT_MAX bytes.

11329 Make it possible to run ./temacs.
11331 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11332 syms_of_callproc does the same thing. Remove test for

11352 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11354 * eval.c (Qdebug): Now static.
11355 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11356 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11357 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11359 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11361 * image.c: Various fixes to ImageMagick code comments.
11362 (Fimagemagick_types): Doc fix.
11364 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11366 Minor fixes prompted by GCC 4.6.0 warnings.
11368 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11370 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11371 (x_clipboard_manager_save_all): Move extern decl to ...
11372 * xterm.h: ... here, so that it can be checked for consistency.
11374 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11376 * xselect.c (x_clipboard_manager_save_frame)
11377 (x_clipboard_manager_save_all): New functions.
11378 (Fx_clipboard_manager_save): Lisp function deleted.
11380 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11381 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11383 * xterm.h: Update prototype.
11385 2011-05-28 William Xu <william.xwl@gmail.com>
11387 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11388 exiting (Bug#8239).
11390 2011-05-28 Jim Meyering <meyering@redhat.com>
11392 Avoid a sign-extension bug in crypto_hash_function.
11393 * fns.c (to_uchar): Define.
11394 (crypto_hash_function): Use it to convert some newly-signed
11395 variables to unsigned, to avoid sign-extension bugs. For example,
11396 without this change, (md5 "truc") would evaluate to
11397 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11398 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11399 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11401 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11403 Integer overflow fixes.
11405 * dbusbind.c: Serial number integer overflow fixes.
11406 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11407 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11408 to hold a serial number that is too large for a fixnum.
11409 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11410 Check for serial numbers out of range. Decode any serial number
11411 that was so large that it became a float. (Bug#8722)
11413 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11414 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11415 Use XFASTINT rather than XUINT when numbers are nonnegative.
11416 (xd_append_arg, Fdbus_method_return_internal):
11417 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11418 arguments, check that Lisp number is nonnegative, rather than
11419 silently wrapping negative numbers around. (Bug#8722)
11420 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11423 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11425 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11427 ccl: Add integer overflow checks.
11428 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11429 (IN_INT_RANGE): New macros.
11430 (ccl_driver): Use them to check for integer overflow when
11431 decoding a CCL program. Many of the new checks are whether XINT (x)
11432 fits in int; it doesn't always, on 64-bit hosts. The new version
11433 doesn't catch all possible integer overflows, but it's an
11434 improvement. (Bug#8719)
11436 * alloc.c (make_event_array): Use XINT, not XUINT.
11437 There's no need for unsigned here.
11439 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11440 This follows up to the 2011-05-06 change that substituted uintptr_t
11441 for EMACS_INT. This case wasn't caught back then.
11443 Rework Fformat to avoid integer overflow issues.
11444 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11445 now (part of C89). Include <verify.h>.
11446 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11447 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11448 (Fformat): Avoid the prepass trying to compute sizes; it was only
11449 approximate and thus did not catch overflow reliably. Instead, walk
11450 through the format just once, formatting and computing sizes as we go,
11451 checking for integer overflow at every step, and allocating a larger
11452 buffer as needed. Keep track separately whether the format is
11453 multibyte. Keep only the most-recently calculated precision, rather
11454 than them all. Record whether each argument has been converted to
11455 string. Use EMACS_INT, not int, for byte and char and arg counts.
11456 Support field widths and precisions larger than INT_MAX. Avoid
11457 sprintf's undefined behavior with conversion specifications such as %#d
11458 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11459 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11460 formatting out-of-range floating point numbers with int
11461 formats. (Bug#8668)
11463 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11465 * data.c: Avoid integer truncation in expressions involving floats.
11466 * data.c: Include <intprops.h>.
11467 (arith_driver): When there's an integer overflow in an expression
11468 involving floating point, convert the integers to floating point
11469 so that the resulting value does not suffer from catastrophic
11470 integer truncation. For example, on a 64-bit host (* 4
11471 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11472 Do not rely on undefined behavior after integer overflow.
11474 merge count_size_as_multibyte, parse_str_to_multibyte
11475 * character.c, character.h (count_size_as_multibyte):
11476 Rename from parse_str_to_multibyte; all uses changed.
11477 Check for integer overflow.
11478 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11479 since it's now a duplicate of the other. This is more of
11480 a character than a buffer op, so better that it's in character.c.
11481 * fns.c, print.c: Adjust to above changes.
11483 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11485 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11487 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11489 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11490 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11491 (x_clipboard_manager_save): Now static.
11492 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11494 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11495 (crypto_hash_function): Now static.
11496 Fix pointer signedness problems. Avoid unnecessary initializations.
11498 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11500 * termhooks.h (Vselection_alist): Make it terminal-local.
11502 * terminal.c (create_terminal): Initialize it.
11504 * xselect.c: Support for clipboard managers.
11505 (Vselection_alist): Move to termhooks.h as terminal-local var.
11506 (LOCAL_SELECTION): New macro.
11507 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11508 (symbol_to_x_atom): Remove gratuitous arg.
11509 (x_handle_selection_request, lisp_data_to_selection_data)
11510 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11511 (x_own_selection, x_get_local_selection, x_convert_selection):
11512 New arg, specifying work frame. Use terminal-local Vselection_alist.
11513 (some_frame_on_display): Delete unused function.
11514 (Fx_own_selection_internal, Fx_get_selection_internal)
11515 (Fx_disown_selection_internal, Fx_selection_owner_p)
11516 (Fx_selection_exists_p): New optional frame arg.
11517 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11518 (x_handle_selection_clear): Don't treat other terminals with the
11519 same keyboard specially. Use the terminal-local Vselection_alist.
11520 (x_clear_frame_selections): Use Frun_hook_with_args.
11522 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11524 * xterm.h: Add support for those atoms.
11526 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11528 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11529 (converted_selections, conversion_fail_tag): New global variables.
11530 (x_selection_request_lisp_error): Free the above.
11531 (x_get_local_selection): Remove unnecessary code.
11532 (x_reply_selection_request): Args changed; handle arbitrary array
11533 of converted selections stored in converted_selections.
11534 Separate the XChangeProperty and SelectionNotify steps.
11535 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11536 (x_convert_selection): New function.
11537 (x_handle_selection_event): Simplify.
11538 (x_get_foreign_selection): Don't ignore incoming requests while
11539 waiting for an answer; this will fail when we implement
11540 SAVE_TARGETS, and seems unnecessary anyway.
11541 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11542 (Vx_sent_selection_functions): Doc fix.
11544 2011-05-26 Leo Liu <sdl.web@gmail.com>
11546 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11548 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11550 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11552 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11553 for fringe update if it has periodic bitmap.
11554 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11555 and fringe_bitmap_periodic_p.
11557 * fringe.c (get_fringe_bitmap_data): New function.
11558 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11559 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11560 row. Mark glyph row for fringe update if periodicity changed.
11562 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11563 for fringe update unless it has periodic bitmap.
11565 2011-05-25 Kenichi Handa <handa@m17n.org>
11567 * xdisp.c (get_next_display_element): Set correct it->face_id for
11568 a static composition.
11570 2011-05-24 Leo Liu <sdl.web@gmail.com>
11573 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11575 * fns.c (crypto_hash_function, Fsha1): New function.
11576 (Fmd5): Use crypto_hash_function.
11577 (syms_of_fns): Add Ssha1.
11579 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11581 * gnutls.c: Remove unused macros.
11582 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11583 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11584 Remove macros that are defined and never used.
11585 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11587 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11589 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11590 (Fx_get_selection_internal): Minor cleanup.
11591 (Fx_own_selection_internal): Rename arguments for consistency with
11594 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11596 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11598 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11600 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11602 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11604 * dispnew.c (scrolling_window): Don't exclude the case that the
11605 last enabled row in the desired matrix touches the bottom boundary.
11607 2011-05-21 Glenn Morris <rgm@gnu.org>
11609 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11610 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11611 and add some more files.
11613 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11615 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11616 report_file_error introduced by the change from 2011-05-07.
11618 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11620 * systime.h (Time): Define only if emacs is defined.
11621 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11622 where the include path doesn't have X11/X.h by default. See
11623 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11625 2011-05-20 Kenichi Handa <handa@m17n.org>
11627 * composite.c (find_automatic_composition): Fix previous change.
11629 2011-05-20 Glenn Morris <rgm@gnu.org>
11631 * lisp.mk: New file, split from Makefile.in.
11632 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11633 (shortlisp): Remove.
11634 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11636 2011-05-19 Glenn Morris <rgm@gnu.org>
11638 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11639 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11640 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11641 (lisp): Set the order to that of loadup.el.
11642 (shortlisp): Make it a copy of $lisp.
11643 (SOME_MACHINE_LISP): Remove.
11644 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11645 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11647 2011-05-18 Kenichi Handa <handa@m17n.org>
11649 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11650 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11651 (find_automatic_composition): Mostly rewrite for efficiency.
11653 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11655 * makefile.w32-in: Update dependencies.
11657 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11659 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11660 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11662 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11664 Fix some integer overflow issues, such as string length overflow.
11666 * insdel.c (count_size_as_multibyte): Check for string overflow.
11668 * character.c (lisp_string_width): Check for string overflow.
11669 Use EMACS_INT, not int, for string indexes and lengths; in
11670 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11671 the resulting string length overflows an EMACS_INT; instead,
11672 report a string overflow if no precision given. When checking for
11673 precision exhaustion, use a check that cannot possibly have
11674 integer overflow. (Bug#8675)
11675 * character.h (lisp_string_width): Adjust to new signature.
11677 * alloc.c (string_overflow): New function.
11678 (Fmake_string): Use it. This doesn't change behavior, but saves
11679 a few bytes and will simplify future changes.
11680 * character.c (string_escape_byte8): Likewise.
11681 * lisp.h (string_overflow): New decl.
11683 Fixups, following up to the user-interface timestamp change.
11684 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11685 for UI timestamps, instead of unsigned long.
11686 * msdos.c (mouse_get_pos): Likewise.
11687 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11688 * w32gui.h (Time): Define by including "systime.h" rather than by
11689 declaring it ourselves. (Bug#8664)
11691 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11692 * image.c (clear_image_cache): Likewise.
11694 * term.c (term_mouse_position): Don't assume time_t wraparound.
11696 Be more systematic about user-interface timestamps.
11697 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11698 and sometimes 'EMACS_UINT', to represent these timestamps.
11699 This change causes it to use 'Time' uniformly, as that's what X uses.
11700 This makes the code easier to follow, and makes it easier to catch
11701 integer overflow bugs such as Bug#8664.
11702 * frame.c (Fmouse_position, Fmouse_pixel_position):
11703 Use Time, not unsigned long, for user-interface timestamps.
11704 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11705 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11706 * keyboard.h (last_event_timestamp): Likewise.
11707 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11708 * menu.h (xmenu_show): Likewise.
11709 * term.c (term_mouse_position): Likewise.
11710 * termhooks.h (struct input_event.timestamp): Likewise.
11711 (struct terminal.mouse_position_hook): Likewise.
11712 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11713 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11714 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11715 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11716 what it was before.
11717 * menu.h, termhooks.h: Include "systime.h", for Time.
11719 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11720 Don't assume that the difference between two unsigned long values
11721 can fit into an integer. At this point, we know button_down_time
11722 <= event->timestamp, so the difference must be nonnegative, so
11723 there's no need to cast the result if double-click-time is
11724 nonnegative, as it should be; check that it's nonnegative, just in
11725 case. This bug is triggered when events are more than 2**31 ms
11726 apart (about 25 days). (Bug#8664)
11728 * xselect.c (last_event_timestamp): Remove duplicate decl.
11729 (x_own_selection): Remove needless cast to unsigned long.
11731 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11732 that always fit in int. Use a sentinel instead of a counter, to
11733 avoid a temp and to allay GCC's concerns about possible int overflow.
11734 * frame.h (struct frame): Use int for menu_bar_items_used
11735 instead of EMACS_INT, since it always fits in int.
11737 * menu.c (grow_menu_items): Check for int overflow.
11739 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11741 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11742 Before, the code was not consistent. These values cannot exceed
11743 2**31 - 1 so there's no need to make them unsigned.
11744 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11745 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11746 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11748 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11750 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11751 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11752 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11753 presumably because the widths might not match.
11755 * window.c (size_window): Avoid needless test at loop start.
11757 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11759 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11761 2011-05-12 Drew Adams <drew.adams@oracle.com>
11763 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11765 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11767 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11768 `width' to `bar_area_x' and `bar_area_width', respectively.
11769 (x_scroll_run): Take account of fringe background extension.
11771 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11772 Rename local vars `left' and `width' to `bar_area_x' and
11773 `bar_area_width', respectively.
11774 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11775 background extension.
11777 2011-05-10 Jim Meyering <meyering@redhat.com>
11779 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11781 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11783 * image.c (Finit_image_library): Return t for built-in image types,
11784 like pbm and xbm. (Bug#8640)
11786 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11788 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11790 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11792 * w32console.c (Fset_screen_color): Doc fix.
11793 (Fget_screen_color): New function.
11794 (syms_of_ntterm): Defsubr it.
11796 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11797 unlink the temporary file if Fcall_process didn't create it in the
11799 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11800 child process will be redirected to a file specified with `:file'.
11801 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11802 cue to call_process_cleanup not to close that handle.
11804 2011-05-07 Ben Key <bkey76@gmail.com>
11806 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11807 one of two shell specific rules, either bootstrap-temacs-CMD or
11808 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11809 to the previous implementation of the bootstrap-temacs rule.
11810 The bootstrap-temacs-CMD rule is similar to the previous
11811 implementation of the bootstrap-temacs rule except that it
11812 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11815 These changes, along with some changes to nt/configure.bat,
11816 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11817 earlier fix to add support for --cflags and --ldflags options
11818 that include quotes so that it works whether make uses cmd or
11821 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11823 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11824 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11826 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11827 a string. Handle both cases.
11828 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11829 (Fdbus_register_method): Use Qinvalid_function.
11831 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11833 * makefile.w32-in: Update dependencies.
11834 (LISP_H): Add inttypes.h and stdin.h.
11835 (PROCESS_H): Add unistd.h.
11837 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11839 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11840 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11842 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11844 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11846 * term.c (vfatal): Remove stray call to va_end.
11847 It's not needed and the C Standard doesn't allow it here anyway.
11849 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11850 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11852 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11855 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11857 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11859 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11861 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11863 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11865 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11866 * charset.c (Fdefine_charset_internal): Don't initialize
11867 charset.code_space[15]. The value was garbage, on hosts with
11868 32-bit int (Bug#8600).
11870 * lread.c (read_integer): Be more consistent with string-to-number.
11871 Use string_to_number to do the actual conversion; this avoids
11872 rounding errors and fixes some other screwups. Without this fix,
11873 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11874 (digit_to_number): Move earlier, for benefit of read_integer.
11875 Return -1 if the digit is out of range for the base, -2 if it is
11876 not a digit in any supported base. (Bug#8602)
11878 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11880 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11881 to match comment at start of function. This also removes a
11882 GCC warning about overflow in a 32+64-bit port.
11884 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11886 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11887 Reported by Stefan Monnier in
11888 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11889 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11890 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11892 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11893 (EMACS_UINTPTR): Likewise, with uintptr_t.
11895 * lisp.h: Prefer 64-bit EMACS_INT if available.
11896 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11897 on 32-bit hosts that have 64-bit int, so that they can access
11899 However, temporarily disable this change unless the temporary
11900 symbol WIDE_EMACS_INT is defined.
11902 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11904 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11905 This removes an assumption that EMACS_INT and long are the same
11906 width as pointers. The assumption is true for Emacs porting targets
11907 now, but we want to make other targets possible.
11908 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11909 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11910 In the rest of the code, change types of integers that hold casted
11911 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11912 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11913 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11914 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11915 No need to cast type when ORing.
11916 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11917 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11918 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11919 assume EMACS_INT is the same width as char *.
11920 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11921 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11922 Remove no-longer-needed casts.
11923 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11924 (xg_tool_bar_help_callback, xg_make_tool_item):
11925 Use EMACS_INTPTR to hold an integer
11926 that will be cast to void *; this can avoid a GCC warning
11927 if EMACS_INT is not the same width as void *.
11928 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11929 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11930 (current_message_1, set_message_1):
11931 Use a local to convert to proper width without a cast.
11932 * xmenu.c (dialog_selection_callback): Likewise.
11934 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11935 Also, don't assume VALBITS / RAND_BITS is less than 5,
11936 and don't rely on undefined behavior when shifting a 1 left into
11938 * lisp.h (get_random): Change signature to match.
11940 * lread.c (hash_string): Use size_t, not int, for hash computation.
11941 Normally we prefer signed values; but hashing is special, because
11942 it's better to use unsigned division on hash table sizes so that
11943 the remainder is nonnegative. Also, size_t is the natural width
11944 for hashing into memory. The previous code used 'int', which doesn't
11945 retain enough info to hash well into very large tables.
11946 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11948 * dbusbind.c: Don't possibly lose pointer info when converting.
11949 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11950 Use XPNTR rather than XHASH, so that the high-order bits of
11951 the pointer aren't lost when converting through void *.
11953 * eval.c (Fautoload): Don't double-shift a pointer.
11955 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11957 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11959 * gnutls.c (DEF_GNUTLS_FN):
11960 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11962 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11964 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11967 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11969 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11970 New version that can reserve upto 2GB of heap space.
11972 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11974 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11976 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11978 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11979 `gnutls_certificate_set_x509_key_file'.
11981 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11983 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11984 Update dependencies.
11986 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11988 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11989 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11990 Remove unused parameter `fildes'.
11991 * process.c (read_process_output, send_process): Don't pass it.
11993 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11995 Fix previous change: the library cache is defined in w32.c.
11996 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11997 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11999 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12001 Implement dynamic loading of GnuTLS on Windows.
12003 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12004 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12005 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12008 * gnutls.c (Qgnutls_dll): Define.
12009 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12010 (gnutls_*): Declare function pointers.
12011 (init_gnutls_functions): New function to initialize function pointers.

12014 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12015 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12016 (emacs_gnutls_write, emacs_gnutls_read)
12017 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12018 (Fgnutls_available_p): New function.
12019 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

12027 (w32_delayed_load): Move to w32.c.
12029 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12031 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12032 (w32_delayed_load): Move from image.c. When loading a library, record
12033 its filename in the :loaded-from property of the library id.
12034 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12035 Initialize and staticpro them.
12036 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12038 * process.c: Include lisp.h before w32.h, not after.
12039 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12040 instead of gnutls_record_check_pending.
12042 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12044 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12046 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12047 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12050 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12052 * xterm.c (x_set_frame_alpha): Do not set property on anything
12053 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12055 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12057 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12059 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12061 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

12075 * sysdep.c (wait_for_termination_1): Make static.
12076 (wait_for_termination, interruptible_wait_for_termination):
12077 Move after wait_for_termination_1.
12079 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12081 * sysdep.c (interruptible_wait_for_termination): New function
12082 which is like wait_for_termination, but allows keyboard
12085 * callproc.c (Fcall_process): Add (:file "file") as an option for
12087 (Fcall_process_region): Ditto.
12089 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12091 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12092 rather than `XVECTOR (FOO)->size'.
12094 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12095 inttypes.h, as a gnulib replacement is used if it not available in
12098 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12100 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12101 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12102 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12104 * coding.c (coding_alloc_by_realloc): Error out if destination
12105 will grow beyond MOST_POSITIVE_FIXNUM.
12106 (decode_coding_emacs_mule): Abort if there isn't enough place in
12107 charbuf for the composition carryover bytes. Reserve an extra

12115 aborting when %lld or %lll format is passed.
12116 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12117 %llo or %llx format is passed. (Bug#8545)
12119 * window.c (window_scroll_line_based): Use a marker instead of
12120 simple variables to record original value of point. (Bug#7952)
12122 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12123 produced by %s or %c overflows available buffer space. (Bug#8545)
12125 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12127 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12128 (SIZE_MAX): Move defn after all includes, as they might #define it.
12130 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12132 * w32.c (init_environment): Warn about defaulting HOME to C:\.

12152 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12154 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12156 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12158 * makefile.w32-in: Update dependencies.
12160 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12162 Improve `doprnt' and its usage. (Bug#8545)
12163 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12164 `format_end'. Remove support for %l as a conversion specifier.
12165 Don't use xrealloc. Improve diagnostics when the %l size modifier
12166 is used. Update the commentary.
12168 * eval.c (verror): Simplify calculation of size_t.
12170 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12173 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12175 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12178 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12180 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12181 This makes this file independent of the recent pseudovector change.
12183 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12185 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12187 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12188 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12189 Remove unused local.
12190 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12192 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12193 GCC 4.6.0 optimizes based on type-based alias analysis.
12194 For example, if b is of type struct buffer * and v of type struct
12195 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12196 != &v->size, and therefore "v->size = 1; b->size = 2; return
12197 v->size;" must therefore return 1. This assumption is incorrect
12198 for Emacs, since it type-puns struct Lisp_Vector * with many other
12199 types. To fix this problem, this patch adds a new type struct
12200 vectorlike_header that documents the constraints on layout of vectors
12201 and pseudovectors, and helps optimizing compilers not get fooled
12202 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12203 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12204 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12206 (XSETPVECTYPE): Rewrite in terms of new macro.
12207 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12208 This is a bit clearer, and further avoids the possibility of
12209 undesirable aliasing.
12210 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12211 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12212 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12213 since Lisp_Subr is a special case (no "next" field).
12214 (ASIZE): Now uses header.size rather than size.
12215 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12216 to avoid the hassle of writing XVECTOR (foo)->header.size.
12217 (struct vectorlike_header): New type.
12218 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12219 object, to help avoid aliasing.
12220 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12221 (SUBRP): Likewise, since Lisp_Subr is a special case.
12222 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12223 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12224 (struct Lisp_Hash_Table): Combine first two members into a single
12225 struct vectorlike_header member. All uses of "size" and "next" members
12226 changed to be "header.size" and "header.next".
12227 * buffer.h (struct buffer): Likewise.
12228 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12229 * frame.h (struct frame): Likewise.
12230 * process.h (struct Lisp_Process): Likewise.
12231 * termhooks.h (struct terminal): Likewise.
12232 * window.c (struct save_window_data, struct saved_window): Likewise.
12233 * window.h (struct window): Likewise.
12234 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12235 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12236 * buffer.c (init_buffer_once): Likewise.
12237 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12239 * process.c (Fformat_network_address): Use local var for size,
12242 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12244 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12245 * data.c (atof): Remove decl; no longer used or needed.
12246 (digit_to_number): Move to lread.c.
12247 (Fstring_to_number): Use new string_to_number function, to be
12248 consistent with how the Lisp reader treats infinities and NaNs.
12249 Do not assume that floating-point numbers represent EMACS_INT
12250 without losing information; this is not true on most 64-bit hosts.
12251 Avoid double-rounding errors, by insisting on integers when
12252 parsing non-base-10 numbers, as the documentation specifies.
12253 * lisp.h (string_to_number): New decl, replacing ...
12254 (isfloat_string): Remove.
12255 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12256 (read1): Do not accept +. and -. as integers; this
12257 appears to have been a coding error. Similarly, do not accept
12258 strings like +-1e0 as floating point numbers. Do not report
12259 overflow for integer overflows unless the base is not 10 which
12260 means we have no simple and reliable way to continue.
12261 Break out the floating-point parsing into a new
12262 function string_to_number, so that Fstring_to_number parses
12263 floating point numbers consistently with the Lisp reader.
12264 (digit_to_number): Move here from data.c. Make it static inline.
12265 (E_CHAR, EXP_INT): Remove, replacing with ...
12266 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12267 (string_to_number): New function, replacing isfloat_string.
12268 This function checks for valid syntax and produces the resulting
12269 Lisp float number too. Rework it so that string-to-number
12270 no longer mishandles examples like "1.0e+". Use strtoumax,
12271 so that overflow for non-base-10 numbers is reported only when
12272 there's no portable and simple way to convert to floating point.
12274 * textprop.c (set_text_properties_1): Rewrite for clarity,
12275 and to avoid GCC warning about integer overflow.
12277 * intervals.h (struct interval): Use EMACS_INT for members
12278 where EMACS_UINT might cause problems. See
12279 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12280 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12281 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12283 (offset_intervals): Tell GCC not to worry about length overflow
12284 when negating a negative length.
12286 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12287 (overrun_check_free): Likewise.
12289 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12290 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12293 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12294 (gnutls_make_error): Rename local to avoid shadowing.
12295 (gnutls_emacs_global_deinit): ifdef out; not used.
12296 (Fgnutls_boot): Use const for pointer to readonly storage.
12297 Comment out unused local. Fix pointer signedness problems.
12299 * lread.c (openp): Don't stuff size_t into an 'int'.
12300 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12301 about possible signed overflow.
12303 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12304 (GDK_KEY_g): Don't define if already defined.
12305 (xg_prepare_tooltip): Avoid pointer signedness problem.
12306 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12308 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12309 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12311 * xfns.c (Fx_window_property): Simplify a bit,
12312 to make a bit faster and to avoid GCC 4.6.0 warning.
12313 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12315 * fns.c (internal_equal): Don't assume size_t fits in int.
12317 * alloc.c (compact_small_strings): Tighten assertion a little.
12319 Replace pEd with more-general pI, and fix some printf arg casts.
12320 * lisp.h (pI): New macro, generalizing old pEd macro to other
12321 conversion specifiers. For example, use "...%"pI"d..." rather
12322 than "...%"pEd"...".
12323 (pEd): Remove. All uses replaced with similar uses of pI.
12324 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12325 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12326 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12327 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12328 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12329 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12330 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12332 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12333 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12334 * print.c (safe_debug_print, print_object): Likewise.
12335 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12337 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12338 avoiding the 0 flag, which is not portable.
12339 * process.c (Fmake_network_process): Use pI to avoid cast.
12340 * region-cache.c (pp_cache): Likewise.
12341 * xdisp.c (decode_mode_spec): Likewise.
12342 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12343 behavior on 64-bit hosts with printf arg.
12344 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12345 (x_stop_queuing_selection_requests): Likewise.
12346 (x_get_window_property): Don't truncate byte count to an 'int'
12349 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12350 here, since it parses constructs like leading '-' and spaces,
12351 which are not wanted; and it overflows with large numbers.
12352 Instead, simply match F[0-9]+, which is what is wanted anyway.
12354 * alloc.c: Remove unportable assumptions about struct layout.
12355 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12356 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12357 (allocate_vectorlike, make_pure_vector): Use the new macros,
12358 plus offsetof, to remove unportable assumptions about struct layout.
12359 These assumptions hold on all porting targets that I know of, but
12360 they are not guaranteed, they're easy to remove, and removing them
12361 makes further changes easier.
12363 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12364 This doesn't fix a bug but makes the code clearer.
12365 (string_overrun_cookie): Now const. Use initializers that
12366 don't formally overflow signed char, to avoid warnings.
12367 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12368 can cause Emacs to crash when string overrun checking is enabled.
12369 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12370 multiple of sizeof (EMACS_INT); it need not be, if
12371 alignof(EMACS_INT) < sizeof (EMACS_INT).
12372 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12374 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

12381 supposed to be handshaking. (Bug#8556)
12382 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12384 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

12394 * alloc.c (check_sblock, check_string_bytes)
12395 (check_string_free_list): Convert to standard C.
12397 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12399 * w32.c (emacs_gnutls_push): Fix typo.
12401 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12403 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12404 "cast to pointer from integer of different size".
12406 Improve doprnt and its use in verror. (Bug#8545)
12407 * doprnt.c (doprnt): Document the set of format control sequences
12408 supported by the function. Use SAFE_ALLOCA instead of always
12411 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12412 is one byte too soon. Don't use xrealloc; instead xfree and
12415 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12417 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12420 * gnutls.c: Renamed global_initialized to
12421 gnutls_global_initialized. Added internals for the
12422 :verify-hostname-error, :verify-error, and :verify-flags
12423 parameters of `gnutls-boot' and documented those parameters in the
12424 docstring. Start callback support.
12425 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12426 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12427 on error. Return error code.

12429 (emacs_gnutls_read): Likewise.
12430 (Fgnutls_boot): Return handshake error code.
12431 (emacs_gnutls_handle_error): New function.

12487 changes in globals.h immediately force recompilation.
12488 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12489 $(CURDIR)/s/ms-w32.h.

12494 <char-direction-table>: Deleted.
12496 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12498 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12499 * doprnt.c: Include limits.h.
12500 (SIZE_MAX): New macro.
12501 (doprnt): Return a size_t value. 2nd arg is now size_t.
12502 Many local variables are now size_t instead of int or unsigned.
12503 Improve overflow protection. Support `l' modifier for integer
12504 conversions. Support %l conversion. Don't assume an EMACS_INT
12505 argument for integer conversions and for %c.
12507 * lisp.h (doprnt): Restore prototype.
12509 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12510 $(SRC)/character.h.
12512 * Makefile.in (base_obj): Add back doprnt.o.
12514 * deps.mk (doprnt.o): Add back prerequisites.
12515 (callint.o): Depend on character.h.
12517 * eval.c (internal_lisp_condition_case): Include the handler
12518 representation in the error message.
12519 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12520 when breaking from the loop.

12524 * callint.c (Fcall_interactively): When displaying error message
12525 about invalid control letter, pass the character's codepoint, not
12526 a pointer to its multibyte form. Improve display of the character
12527 in octal and display also its hex code.
12529 * character.c (char_string): Use %x to display the (unsigned)
12530 codepoint of an invalid character, to avoid displaying a bogus
12533 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12534 `error', not SYMBOL_NAME itself.
12536 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12537 character arguments to `error'.
12539 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12540 to `error' in error message about FINAL_CHAR argument. Make sure
12541 FINAL_CHAR is a character, and use %c when it is passed as
12542 argument to `error'.

12606 Define only if needed.
12608 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
12609 by pacifying GCC about it. Maybe it's time to retire it?
12610 * xfaces.c (USG, __TIMEVAL__): Likewise.
12612 * dispextern.h (struct redisplay_interface): Rename param
12613 to avoid shadowing.
12614 * termhooks.h (struct terminal): Likewise.
12615 * xterm.c (xembed_send_message): Likewise.
12617 * insdel.c (make_gap_smaller): Define only if
12618 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
12620 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
12623 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
12624 so that we aren't warned about unused symbols.
12626 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
12628 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
12630 * xfns.c (x_real_positions): Mark locals as initialized.
12632 * xmenu.c (xmenu_show): Don't use uninitialized vars.

12635 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
12636 (x_dispatch_event): Declare static if USE_GTK, and
12637 define if USE_GTK || USE_X_TOOLKIT.
12638 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
12639 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
12640 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
12641 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
12643 * xmenu.c (menu_help_callback): Pointer type fixes.
12644 Use const pointers when pointing at readonly data. Avoid pointer

12660 * bitmaps: Change bitmaps from unsigned char back to the X11
12661 compatible char. Avoid the old compiler warnings about
12662 out-of-range initializers by using, for example, '\xab' rather
12665 * xgselect.c (xgselect_initialize): Check vs interface
12666 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

12731 * nsfont.m: Fixed bugs in ns_get_family and
12732 ns_descriptor_to_entity that were caused by using free to

12735 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
12736 --enable-checking=xmallocoverrun). xfree is now used to
12737 deallocate these memory blocks.

13106 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13108 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13109 it's not optimized away by whole-program optimization.
13110 (message_enable_multibyte, free_misc): Remove.
13111 (catchlist, handlerlist, mark_backtrace):
13112 Declare only if BYTE_MARK_STACK.
13113 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
13114 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
13115 (message_enable_multibyte): Remove decl.
13116 (free_misc, interval_free_list, float_block, float_block_index):
13117 (n_float_blocks, float_free_list, cons_block, cons_block_index):
13118 (cons_free_list, last_marked_index):
13120 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
13121 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13122 (mark_backtrace): Define only if BYTE_MARK_STACK.
13123 * xdisp.c (message_enable_multibyte): Now static.
13125 Declare Lisp_Object Q* variables to be 'static' if not exported.
13126 This makes it easier for human readers (and static analyzers)
13127 to see whether these variables are used from other modules.
13128 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13129 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
13130 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
13131 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
13132 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
13133 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
13134 * xmenu.c, xselect.c:
13135 Declare Q* vars static if they are not used in other modules.
13136 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
13137 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
13138 Remove decls of unexported vars.
13139 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13141 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13143 Make Emacs functions such as Fatom 'static' by default.
13144 This makes it easier for human readers (and static analyzers)
13145 to see whether these functions can be called from other modules.
13146 DEFUN now defines a static function. To make the function external
13147 so that it can be used in other C modules, use the new macro DEFUE.
13148 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13149 (Finit_image_library):
13150 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13151 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13152 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13153 Remove decls, since these functions are now static.
13154 (Funintern, Fget_internal_run_time): New decls, since these functions
13155 were already external.
13157 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13158 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
13159 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
13160 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
13161 * keyboard.c, keymap.c, lread.c:
13162 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
13163 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
13164 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13165 Mark functions with DEFUE instead of DEFUN,
13166 if they are used in other modules.
13167 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13168 decls for now-static functions.
13169 * buffer.h (Fdelete_overlay): Remove decl.
13170 * callproc.c (Fgetenv_internal): Mark as internal.
13171 * composite.c (Fremove_list_of_text_properties): Remove decl.

13175 * doc.c (Fdocumntation_property): New forward static decl.
13176 * eval.c (Ffetch_bytecode): New forward static decl.
13177 (Funintern): Remove extern decl; now in .h file where it belongs.
13178 * fileio.c (Fmake_symbolic_link): New forward static decl.
13179 * image.c (Finit_image_library): New forward static decl.
13180 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13181 * intervals.h (Fprevious_property_change):
13182 (Fremove_list_of_text_properties): Remove decls.
13183 * keyboard.c (Fthis_command_keys): Remove decl.
13184 (Fcommand_execute): New forward static decl.
13185 * keymap.c (Flookup_key): New forward static decl.
13186 (Fcopy_keymap): Now static.
13187 * keymap.h (Flookup_key): Remove decl.
13188 * process.c (Fget_process): New forward static decl.
13189 (Fprocess_datagram_address): Mark as internal.
13190 * syntax.c (Fsyntax_table_p): New forward static decl.
13191 (skip_chars): Remove duplicate decl.

13200 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13202 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13205 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13207 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13208 when at ZV. (Bug#8487)
13210 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13212 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13214 * keyboard.c (parse_tool_bar_item): Likewise.
13215 * sound.c (sound_cleanup, alsa_close): Likewise.
13216 * termcap.c (tgetent): Likewise.
13217 * xfns.c (x_default_font_parameter): Likewise.
13218 * xsettings.c (read_and_apply_settings): Likewise.
13220 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13221 (overrun_check_free): Protoize.
13223 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13225 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13226 since callers should never pass a negative size.
13227 Change the signature to match that of plain 'read' and 'write'; see
13228 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13229 * lisp.h: Update prototypes of emacs_write and emacs_read.
13231 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13233 * xdisp.c (redisplay_window): Don't try to determine the character
13234 position of the scroll margin if the window start point w->startp
13235 is outside the buffer's accessible region. (Bug#8468)
13237 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13239 Fix write-region and its subroutines for buffers > 2GB.
13240 * fileio.c (a_write, e_write): Modify declaration of arguments and
13241 local variables to support buffers larger than 2GB.
13242 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13244 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13245 argument, local variables, and return value.
13247 * lisp.h: Update prototypes of emacs_write and emacs_read.
13249 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13251 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13253 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13255 Fix more problems found by GCC 4.6.0's static checks.
13257 * xdisp.c (vmessage): Use a better test for character truncation.
13259 * charset.c (load_charset_map): <, not <=, for optimization,
13260 and to avoid potential problems with integer overflow.
13261 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13262 * casetab.c (set_identity, shuffle): Likewise.
13263 * editfns.c (Fformat): Likewise.
13264 * syntax.c (skip_chars): Likewise.
13266 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13267 This also lets GCC 4.6.0 generate slightly better loop code.
13269 * callint.c (Fcall_interactively): <, not <=, for optimization.
13270 (Fcall_interactively): Count the number of arguments produced,
13271 not the number of arguments given. This is simpler and lets GCC
13272 4.6.0 generate slightly better code.
13274 * ftfont.c: Distingish more carefully between FcChar8 and char.
13275 The previous code passed unsigned char * to a functions like
13276 strlen and xstrcasecmp that expect char *, which does not
13277 conform to the C standard.
13278 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13279 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13280 char * when the C standard requires it.
13282 * keyboard.c (read_char): Remove unused var.
13284 * eval.c: Port to Windows vsnprintf (Bug#8435).
13285 Include <limits.h>.
13286 (SIZE_MAX): Define if the headers do not.
13287 (verror): Do not give up if vsnprintf returns a negative count.
13288 Instead, grow the buffer. This ports to Windows vsnprintf, which
13289 does not conform to C99. Problem reported by Eli Zaretskii.
13290 Also, simplify the allocation scheme, by avoiding the need for
13291 calling realloc, and removing the ALLOCATED variable.
13293 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13295 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13296 But keep the doprint source code for now, as we might revamp it
13297 and use it again (Bug#8435).
13298 * lisp.h (doprnt): Remove.
13299 * Makefile.in (base_obj): Remove doprnt.o.
13300 * deps.mk (doprnt.o): Remove.
13302 error: Print 32- and 64-bit integers portably (Bug#8435).
13303 Without this change, on typical 64-bit hosts error ("...%d...", N)
13304 was used to print both 32- and 64-bit integers N, which relied on
13305 undefined behavior.
13306 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13307 * lisp.h (error, verror): Mark as printf-like functions.
13308 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13309 Report overflow in size calculations when allocating printf buffer.
13310 Do not truncate output string at its first null byte.
13311 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13312 Truncate the output at a character boundary, since vsnprintf does not
13314 * charset.c (check_iso_charset_parameter): Convert internal
13315 character to string before calling 'error', since %c now has the
13317 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13318 overflow when computing char to be passed to 'error'. Do not
13319 pass Lisp_Object to 'error'; pass the integer instead.
13320 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13321 formatted with plain %d.
13323 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13325 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13327 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13329 * xterm.c (x_catch_errors): Remove duplicate declaration.
13331 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13333 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13335 2011-04-10 Jim Meyering <meyering@redhat.com>
13337 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13338 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13339 return ssize_t not "int", and use size_t as the buffer length.
13340 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13341 * gnutls.h: Update declarations.
13342 * process.c (read_process_output): Use ssize_t, to match.
13343 (send_process): Likewise.
13345 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13347 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13349 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13351 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13352 Use unsigned char, to match FcChar8 type definition.
13354 * xterm.c (handle_one_xevent):
13355 * xmenu.c (create_and_show_popup_menu):
13356 * xselect.c (x_decline_selection_request)
13357 (x_reply_selection_request): Avoid type-punned deref of X events.
13359 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13361 Fix some uses of `int' instead of EMACS_INT.
13362 * search.c (string_match_1, fast_string_match)
13363 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13364 (scan_buffer, find_next_newline_no_quit)
13365 (find_before_next_newline, search_command, Freplace_match)
13366 (Fmatch_data): Make some `int' variables be EMACS_INT.
13368 * xdisp.c (display_count_lines): 3rd argument and return value now
13369 EMACS_INT. All callers changed.
13370 (pint2hrstr): Last argument is now EMACS_INT.
13372 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13373 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13374 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13375 (decode_coding_utf_16, decode_coding_emacs_mule)
13376 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13377 (decode_coding_ccl, decode_coding_charset)
13378 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13379 (decode_coding_iso_2022, decode_coding_emacs_mule)
13380 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13381 <char_offset, last_offset>: Declare EMACS_INT.
13382 (encode_coding_utf_8, encode_coding_utf_16)
13383 (encode_coding_emacs_mule, encode_invocation_designation)
13384 (encode_designation_at_bol, encode_coding_iso_2022)
13385 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13386 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13388 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13389 (encode_invocation_designation): Last argument P_NCHARS is now
13391 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13392 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13394 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13397 * ccl.c (Fccl_execute_on_string): Declare some variables
13400 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13402 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13404 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13406 * process.c (Fformat_network_address): Doc fix.
13408 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13410 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13412 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13414 * keyboard.c (read_char): Call Lisp function help-form-show,
13415 instead of using internal_with_output_to_temp_buffer.
13416 (Qhelp_form_show): New var.
13417 (syms_of_keyboard): Use DEFSYM macro.
13419 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13421 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13423 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13425 * process.c (Flist_processes): Remove to Lisp.
13426 (list_processes_1): Delete.
13428 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13430 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13432 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13434 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13436 Fix more problems found by GCC 4.6.0's static checks.
13438 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13440 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13442 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13444 * xdisp.c (vmessage): Mark as a printf-like function.
13446 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
13448 * sound.c (sound_warning): Don't crash if arg contains a printf format.
13450 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
13451 printf-like functions.
13452 (tiff_load): Add casts to remove these marks before passing them
13453 to system-supplied API.
13455 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13457 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13458 This avoids several warnings with gcc -Wstrict-overflow.
13459 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13460 directly, rather than having caller test rule sign. This avoids
13461 some unnecessary tests.
13462 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13463 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13464 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13466 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13467 (xfont_open): Avoid unnecessary tests.
13469 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13471 * composite.h, composite.c (composition_gstring_put_cache):
13472 Use EMACS_INT, not int, for length.
13474 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13475 breaking out part of COMPOSITION_DECODE_RULE.
13476 (COMPOSITION_DECODE_RULE): Use it.
13477 * composite.c (get_composition_id): Remove unused local vars,
13478 by using the new macro.
13480 * textprop.c (set_text_properties_1): Change while to do-while,
13481 since the condition is always true at first.
13483 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13484 (interval_deletion_adjustment): Return unsigned value.
13487 * process.c (list_processes_1, create_pty, read_process_output):
13488 (exec_sentinel): Remove vars that were set but not used.
13489 (create_pty): Remove unnecessary "volatile"s.
13490 (Fnetwork_interface_info): Avoid possibility of int overflow.
13491 (read_process_output): Do adaptive read buffering even if carryover.
13492 (read_process_output): Simplify nbytes computation if buffered.
13494 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
13496 * syntax.c (scan_words): Remove var that was set but not used.
13497 (update_syntax_table): Use unsigned instead of int.
13499 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13500 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13501 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13503 * print.c (print_error_message): Avoid int overflow.
13505 * font.c (font_list_entities): Redo for clarity,
13506 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13508 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13509 (font_score): Avoid potential overflow in diff calculation.
13511 * fns.c (substring_both): Remove var that is set but not used.
13512 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13514 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13516 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13517 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13518 can always succeed if overflow has undefined behavior.
13520 * search.c (boyer_moore, wordify): Remove vars set but not used.
13521 (wordify): Omit three unnecessary tests.
13523 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13524 All callers changed. This avoids the need for an unused var.
13526 * casefiddle.c (casify_region): Remove var that is set but not used.
13528 * dired.c (file_name_completion): Remove var that is set but not used.
13530 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13532 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13533 (Finsert_file_contents): Remove unnecessary code checking fd.
13535 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13536 Check for integer overflow on size calculations.
13538 * buffer.c (Fprevious_overlay_change): Remove var that is set
13541 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13542 Remove vars that are set but not used.
13543 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13544 (timer_check_2): Mark vars as initialized.

13549 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13551 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13552 that are set but not used.
13554 * xfns.c (make_invisible_cursor): Don't return garbage
13555 if XCreateBitmapFromData fails (Bug#8410).
13557 * xselect.c (x_get_local_selection, x_handle_property_notify):
13558 Remove vars that are set but not used.
13560 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

13566 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13567 Check for overflow.
13569 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13570 (map_tty_color) [!defined MSDOS]: Likewise.
13572 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13574 * coding.c: Remove vars that are set but not used.
13575 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

13584 * print.c (print_object): Remove var that is set but not used.
13586 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13587 The gnulib version avoids calling malloc in the usual case,
13588 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13589 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13590 * filelock.c (current_lock_owner): Likewise.
13591 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13592 * sysdep.c: Include allocator.h, careadlinkat.h.
13593 (emacs_no_realloc_allocator): New static constant.
13594 (emacs_readlink): New function.
13595 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

13622 do not dereference NULL upon failed strdup
13623 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13624 (ns_get_family): Likewise.
13626 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13628 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13630 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13632 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13635 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13637 Add lexical binding.
13639 * window.c (Ftemp_output_buffer_show): New fun.

13648 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13650 (syms_of_lread): Declare `lexical-binding'.
13652 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13654 * keyboard.c (eval_dyn): New fun.
13655 (menu_item_eval_property): Use it.
13657 * image.c (parse_image_spec): Use Ffunctionp.
13659 * fns.c (concat, mapcar1): Accept byte-code-functions.
13661 * eval.c (Fsetq): Handle lexical vars.
13662 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13663 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13664 (FletX, Flet): Obey lexical binding.
13665 (Fcommandp): Handle closures.
13666 (Feval): New `lexical' arg.
13667 (eval_sub): New function extracted from Feval. Use it almost
13668 everywhere where Feval was used. Look up vars in lexical env.
13670 (Ffunctionp): Move from subr.el.
13671 (Ffuncall): Handle closures.
13672 (apply_lambda): Remove `eval_flags'.
13673 (funcall_lambda): Handle closures and new byte-code-functions.
13674 (Fspecial_variable_p): New function.
13675 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13676 but without exporting it to Lisp.
13678 * doc.c (Fdocumentation, store_function_docstring):
13679 * data.c (Finteractive_form): Handle closures.
13681 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13684 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13686 (exec_byte_code): New function extracted from Fbyte_code to handle new
13687 calling convention for byte-code-functions. Add new byte-codes.
13689 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

13695 * xdisp.c (redisplay_internal): Fix prototype.
13697 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13699 * xdisp.c (SCROLL_LIMIT): New macro.
13700 (try_scrolling): Use it when setting scroll_limit.
13701 Limit scrolling to 100 screen lines.
13702 (redisplay_window): Even when falling back on "recentering",
13703 position point in the window according to scroll-conservatively,
13704 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13706 (try_scrolling): When point is above the window, allow searching
13707 as far as scroll_max, or one screenful, to compute vertical
13708 distance from PT to the scroll margin position. This prevents
13709 try_scrolling from unnecessarily failing when
13710 scroll-conservatively is set to a value slightly larger than the
13711 window height. Clean up the case of PT below the margin at bottom
13712 of window: scroll_max can no longer be INT_MAX. When aggressive
13713 scrolling is in use, don't let point enter the opposite scroll
13714 margin as result of the scroll.
13715 (syms_of_xdisp) <scroll-conservatively>: Document the
13716 threshold of 100 lines for never-recentering scrolling.

13723 (message_log_check_duplicate): Remove parameters `prev_bol' and
13724 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13725 (redisplay_internal): Remove parameter `preserve_echo_area',
13726 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13728 * indent.c (Fvertical_motion):
13729 * window.c (window_scroll_pixel_based, Frecenter):
13730 Don't pass `need_y_p' to `move_it_by_lines'.
13732 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13734 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13735 steal a few bits to be more compact.
13736 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13737 Remove unneeded casts.
13739 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13741 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13743 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13744 binding" message (bug#7967).
13746 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13748 Fix more problems found by GCC 4.6.0's static checks.
13750 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13751 Remove unused local var.
13753 * editfns.c (Fmessage_box): Remove unused local var.
13755 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13756 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13757 Omit unused local vars.
13758 * window.c (shrink_windows): Omit unused local var.
13759 * menu.c (digest_single_submenu): Omit unused local var.
13760 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13761 Omit unused local var.
13763 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13764 Don't assume string length fits in int.
13765 (keyremap_step, read_key_sequence): Use size_t for sizes.

13769 instead of alloca (Bug#8344).
13771 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13772 (Fbacktrace_frame): Don't assume nframes fits in int.
13774 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

13781 * cm.c (calccost): Turn while-do into do-while, for clarity.
13783 * keyboard.c (syms_of_keyboard): Use the same style as later
13784 in this function when indexing through an array. This also
13785 works around GCC bug 48267.
13787 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13789 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13791 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13792 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13794 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13795 This avoids undefined behavior on integer overflow, and is a bit
13796 more convenient anyway since it is compared to a size_t variable.
13798 Variadic C functions now count arguments with size_t, not int.
13799 This avoids an unnecessary limitation on 64-bit machines, which
13800 caused (substring ...) to crash on large vectors (Bug#8344).

13810 * fns.c (concat): Likewise.
13811 * frame.c (x_set_frame_parameters): Likewise.
13812 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13813 0 if not found, not -1. All callers changed.
13815 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13816 (stack_copy_size): Now size_t, not int.
13817 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13819 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13821 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

13838 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13839 don't set the hook to nil, but remove the offending function instead.

13841 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13842 Vcommand_hook_internal.

13980 * w32term.c (x_draw_composite_glyph_string_foreground):
13981 Remove unused variable `width'.
13983 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
13985 * w32term.c (x_set_glyph_string_clipping):
13986 Don't pass uninitialized region to CombineRgn.
13988 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
13990 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

14010 2011-03-23 Julien Danjou <julien@danjou.info>
14012 * term.c (Fsuspend_tty, Fresume_tty):
14013 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14014 * window.c (temp_output_buffer_show):
14015 * insdel.c (signal_before_change):
14016 * frame.c (Fhandle_switch_frame):
14017 * fileio.c (Fdo_auto_save):

14020 * cmds.c (internal_self_insert):
14021 * callint.c (Fcall_interactively):
14022 * buffer.c (Fkill_all_local_variables):
14023 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14025 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14026 unconditionally since it does the check itself.
14028 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14030 Fix more problems found by GCC 4.5.2's static checks.
14032 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14033 the first time through the loop, since we know p0 < p1 then.
14034 This also avoids a gcc -Wstrict-overflow warning.
14036 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14037 leading to a memory leak, possible in functions like
14038 load_charset_map_from_file that can allocate an unbounded number
14039 of objects (Bug#8318).
14041 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14042 that could (at least in theory) be that large.
14044 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14045 This is less likely to overflow, and avoids undefined behavior if
14046 overflow does occur. All callers changed. Use strtoul to scan
14047 for the unsigned long integer.
14048 (pint2hrstr): Simplify and tune code slightly.
14049 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14051 * scroll.c (do_scrolling): Work around GCC bug 48228.
14052 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
14054 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
14055 This also avoids a warning with gcc -Wstrict-overflow.
14056 (validate_x_resource_name): Simplify count usage.
14057 This also avoids a warning with gcc -Wstrict-overflow.
14059 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14062 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14064 * process.c (Fmake_network_process): Use socklen_t, not int,
14065 where POSIX says socklen_t is required in portable programs.
14066 This fixes a porting bug on hosts like 64-bit HP-UX, where
14067 socklen_t is wider than int (Bug#8277).
14068 (Fmake_network_process, server_accept_connection):
14069 (wait_reading_process_output, read_process_output):
14072 * process.c: Rename or move locals to avoid shadowing.

14082 Make tparam.h and terminfo.c consistent.
14083 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14084 Include tparam.h instead, since it declares them.
14085 * cm.h (PC): Remove extern decl; tparam.h now does this.
14086 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14087 * terminfo.c: Include tparam.h, to check interfaces.
14088 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14089 (tparam): Adjust signature to match interface in tparam.h;
14090 this removes some undefined behavior. Check that outstring and len
14091 are zero, which they always are with Emacs.
14092 * tparam.h (PC, BC, UP): New extern decls.
14094 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14095 (xftfont_open): Rename locals to avoid shadowing.
14097 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14098 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14099 (OTF_TAG_SYM): Omit macro if not needed.

14107 * xml.c (make_dom): Now static.
14109 * composite.c (composition_compute_stop_pos): Rename local to
14111 (composition_reseat_it): Remove unused locals.
14112 (find_automatic_composition, composition_adjust_point): Likewise.
14113 (composition_update_it): Mark var as initialized.
14114 (find_automatic_composition): Mark vars as initialized,
14115 with a FIXME (Bug#8290).
14117 character.h: Rename locals to avoid shadowing.
14118 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
14119 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14120 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14121 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14122 to avoid shadowing.
14124 * textprop.c (property_change_between_p): Remove; unused.
14126 * intervals.c (interval_start_pos): Now static.
14128 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

14131 Rename locals to avoid shadowing.
14133 * sound.c (wav_play, au_play, Fplay_sound_internal):
14134 Fix pointer signedness.
14135 (alsa_choose_format): Remove unused local var.
14136 (wav_play): Initialize a variable to 0, to prevent undefined
14137 behavior (Bug#8278).
14139 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14141 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14143 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14144 clobbering (Bug#8298).
14145 * sysdep.c (sys_subshell): Likewise.
14146 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14148 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14149 This should get cleaned up, so that child_setup has the
14150 same signature on all platforms.
14152 * callproc.c (call_process_cleanup): Now static.
14153 (relocate_fd): Rename locals to avoid shadowing.
14155 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14157 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14158 not to be necessary, and produces flickering.
14160 2011-03-20 Glenn Morris <rgm@gnu.org>
14162 * config.in: Remove file.
14164 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14166 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14167 are now in src/globals.h.
14168 (syms_of_minibuf): Remove spurious & from previous change.
14170 2011-03-20 Leo Liu <sdl.web@gmail.com>
14172 * minibuf.c (completing-read-function): New variable.
14173 (completing-read-default): Rename from completing-read.
14174 (completing-read): Call completing-read-function.
14176 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14178 * xfaces.c (Fx_load_color_file):
14179 Read color file from absolute filename (bug#8250).
14181 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14183 * makefile.w32-in: Update dependencies.
14185 2011-03-17 Eli Zaretskii <eliz@gnu.org>
14187 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

14194 (sigchld_handler): Now static.
14196 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14197 That way, the code declares only the vars that it needs.
14198 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
14199 * s/cygwin.h (PTY_ITERATION): Likewise.
14200 * s/darwin.h (PTY_ITERATION): Likewise.

14206 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
14207 (CONSTANTLIM): Remove; unused.
14208 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14209 Define only if needed.
14211 * unexelf.c (unexec): Name an expression,
14212 to avoid gcc -Wbad-function-cast warning.
14213 Use a different way to cause a compilation error if anyone uses
14214 n rather than nn, a way that does not involve shadowing.
14215 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14217 * deps.mk (unexalpha.o): Remove; unused.
14219 New file unexec.h, the (simple) interface for unexec (Bug#8267).
14220 * unexec.h: New file.
14221 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
14222 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
14223 Depend on unexec.h.
14224 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
14225 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
14226 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
14227 Change as necessary to match prototype in unexec.h.
14229 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
14231 (back_comment, skip_chars): Mark vars as initialized.

14245 instead of using an uninitialized var.
14246 (font_sort_entities): Mark var as initialized.
14248 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
14250 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

14274 * callint.c (quotify_arg, quotify_args): Now static.
14275 (Fcall_interactively): Rename locals to avoid shadowing.
14276 Use const pointer when appropriate.

14282 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
14283 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14284 some of which prompt warnings from gcc -Wbad-function-cast.
14285 (Fformat_time_string, Fencode_time, Finsert_char):
14286 (Ftranslate_region_internal, Fformat):
14287 Rename or remove local vars to avoid shadowing.
14288 (Ftranslate_region_internal): Mark var as initialized.
14290 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
14293 * lisp.h (eassert): Check that the argument compiles, even if
14294 ENABLE_CHECKING is not defined.
14296 * data.c (Findirect_variable): Name an expression, to avoid
14297 gcc -Wbad-function-cast warning.

14306 Rename locals to avoid shadowing.
14307 (mark_stack): Move local variables into the #ifdef region where
14309 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
14310 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
14312 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
14313 (GC_STRING_CHARS): Remove; not used.
14314 (Fmemory_limit): Cast sbrk's returned value to char *.
14316 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14317 avoids undefined behavior in theory.
14319 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14321 Use functions, not macros, for up- and down-casing (Bug#8254).
14322 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14323 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14324 to use the following functions instead of these macros.
14325 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14326 EMACS_INT, since callers assume the returned value fits in int.
14327 (upcase1): Likewise, for UPCASE_TABLE.
14328 (uppercasep, lowercasep, upcase): New static inline functions.
14329 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

14334 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14335 (regex_compile, re_search_2, re_match_2_internal):
14336 Remove unused local vars.
14337 (FREE_VAR): Rewrite so as not to use empty "else",
14338 which gcc can warn about.
14339 (regex_compile, re_match_2_internal): Mark locals as initialized.
14340 (RETALLOC_IF): Define only if needed.
14341 (WORDCHAR_P): Likewise. This one is never needed, but is used
14342 only in a comment talking about a compiler bug, so put inside
14343 the #if 0 of that comment.
14344 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14345 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14348 * search.c (boyer_moore): Rename locals to avoid shadowing.
14349 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
14350 (PREV_CHAR_BOUNDARY): Likewise.
14352 * search.c (simple_search): Remove unused var.
14354 * dired.c (compile_pattern): Move decl from here ...

14362 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
14363 Rename locals to avoid shadowing.
14364 (Fvertical_motion): Mark locals as initialized.
14366 * casefiddle.c (casify_object, casify_region): Now static.
14367 (casify_region): Mark local as initialized.
14369 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
14371 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14372 New macros, so that the caller can use some names other than
14373 gcpro1, gcpro2, etc.
14374 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14376 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14377 argument, for consistency with GCPRO2_VAR, etc: it is now the
14378 prefix of the variable, not the variable itself. All uses
14380 * dired.c (directory_files_internal, file_name_completion):
14381 Rename locals to avoid shadowing.
14383 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14384 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14385 dired.c's scmp function, had undefined behavior.
14386 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14387 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14388 * buffer.h: ... to here, because these macros use current_buffer,
14389 and the new implementation with inline functions needs to have
14390 current_buffer in scope now, rather than later when the macros
14392 (downcase, upcase1): New static inline functions.
14393 (DOWNCASE, UPCASE1): Reimplement using these functions.
14394 This avoids undefined behavior in expressions like
14395 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14396 from race conditions in accessing the global variables
14397 case_temp1 and case_temp2.
14398 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14399 * lisp.h (case_temp1, case_temp2): Remove their decls.
14400 * character.h (ASCII_CHAR_P): Move from here ...
14401 * lisp.h: ... to here, so that the inline functions mentioned
14402 above can use them.
14404 * dired.c (directory_files_internal_unwind): Now static.
14406 * fileio.c (file_name_as_directory, directory_file_name):
14407 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14409 (file_name_as_directory): Use const pointers when appropriate.
14410 (Fexpand_file_name): Likewise. In particular, newdir might
14411 point at constant storage, so make it a const pointer.
14412 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14413 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14415 (Fset_file_times, Finsert_file_contents, auto_save_error):
14416 Rename locals to avoid shadowing.
14418 * minibuf.c (choose_minibuf_frame_1): Now static.
14419 (Ftry_completion, Fall_completions): Rename or remove locals
14420 to avoid shadowing.
14422 * marker.c (bytepos_to_charpos): Remove; unused.
14424 * lisp.h (verify_bytepos, count_markers): New decls,
14425 so that gcc does not warn that these functions aren't declared.

14848 All callers of tparam changed to use tparam's actual API.
14849 * tparam.c (tparam1, tparam, tgoto):
14850 Use const pointers where appropriate.
14852 * cm.c (calccost, cmgoto): Use const pointers where appropriate.
14853 * cm.h (struct cm): Likewise.
14854 * dispextern.h (do_line_insertion_deletion_costs): Likewise.
14855 * scroll.c (ins_del_costs, do_line_insertion_deletion_costs): Likewise.
14856 * term.c (tty_ins_del_lines, calculate_costs, struct fkey_table):

14858 (turn_on_face, init_tty): Likewise.
14859 * termchar.h (struct tty_display_info): Likewise.
14861 * term.c (term_mouse_position): Rename local to avoid shadowing.
14863 * alloc.c (mark_ttys): Move decl from here ...
14864 * lisp.h (mark_ttys): ... to here, so that it's checked against defn.
