99 * w32.c (init_environment): Change the default values of many
100 environment variables in dflt_envvars[] to NULL, to avoid pushing
101 them into environment when they were not already defined. Remove
102 the code that deletes site-lisp subdirectories from the default
103 value of EMACSLOADPATH, as it is no longer needed.
104 (check_windows_init_file): Now external, not static. Use
105 Vload_path as is, without adding anything, as this function is now
106 called when Vload_path is already set up.
108 * w32.h (check_windows_init_file): Add prototype.
110 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

115 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
116 any, in the DEFALT argument into the root of the Emacs build or
117 installation tree, as appropriate.
119 * callproc.c (init_callproc_1): Call decode_env_path instead of
120 doing its equivalent by hand.
121 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
122 the code that sets Vexec_path run on MS-Windows.
124 * lread.c (init_lread): Add comments to #ifdef's.
126 * msdos.c (dos_set_window_size, IT_update_begin)
127 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR

134 Now constants, not macros.
136 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
138 Remove unnecessary casts involving pointers.
139 These casts are no longer needed now that we assume C89 or later,
140 since they involve casting to or from void *.
141 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
142 (make_pure_float, make_pure_vector):
143 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

152 (x_get_window_property, x_get_window_property_as_lisp_data):
153 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
154 Remove unnecessary pointer casts.
155 * alloc.c (record_xmalloc): New function.
156 * lisp.h (record_xmalloc): New decl.
157 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
158 more like a function. This is because the pointer cast is not
159 needed. All uses changed.
160 * print.c (print_string, print_error_message): Avoid length recalc.
162 Improve fix for macroexp crash with debugging (Bug#12118).
163 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
164 ARRAY_MARK_FLAG when checking subscripts, because ASET is
165 not supposed to be invoked from the garbage collector.
166 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
167 (gc_aset): New function, which is like ASET but can be
168 used in the garbage collector.

181 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
182 (map_w32_filename): Improve commentary. Simplify switch.
183 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
184 headers (most versions of MinGW w32api don't).
185 (get_security_info, create_symbolic_link)
186 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
188 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
189 in the argument file name.

191 GetFileAttributes fails with network-related error codes.
192 (sys_rename): Diagnose renaming of a symlink when the user doesn't
193 have the required privileges.
194 (get_file_security_desc_by_name): Renamed from
195 get_file_security_desc.
196 (stat_worker): New function, with most of the guts of 'stat', and
197 with addition of handling of symlinks and support for 'lstat'. If
198 possible, get file's attributes and security information by
199 handle, not by name. Produce S_IFLNK bit for symlinks, when
201 (stat, lstat): New functions, call 'stat_worker'.
202 (symlink, readlink, careadlinkat): Rewritten to create and resolve
203 symlinks when the underlying filesystem supports them.
205 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
207 Fix macroexp crash on Windows with debugging (Bug#12118).
208 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
209 checking subscripts; problem introduced with the recent
210 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
211 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
212 since it's used in non-static inline functions now.
214 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
215 Don't assume buffer size fits in 'int'. Remove unused local.
217 Use C99-style 'extern inline' if available.
218 * buffer.h (BUFFER_INLINE):

235 * composite.c (COMPOSITE_INLINE):
236 * dispnew.c (DISPEXTERN_INLINE):
237 * sysdep.c (SYSTIME_INLINE):
238 Define to EXTERN_INLINE, so that the corresponding functions
239 are compiled into code.
240 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
241 (INLINE_HEADER_END): New macros.
242 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

264 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
266 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
267 This how ASET and AREF are supposed to work, and makes
268 it easier to think about future improvements. See
269 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
270 * charset.h (set_charset_attr): New function.

524 does that unconditionally. Remove file, which is now empty.
526 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
529 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

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

680 2012-07-27 Eli Zaretskii <eliz@gnu.org>
682 * alloc.c (listn): Fix the order the arguments are consed onto the
685 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
686 enumeration constants, as PURE and HEAP are too general, and clash
687 with other headers and sources, such as gmalloc.c and the
688 MS-Windows system headers. All users changed.
690 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

705 Improve GDB symbol export (Bug#12036).
706 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different

708 complains about the types in the unevaluated arm when the argument
709 is an integer literal.
710 (xgetint): Simplify expression.
711 * alloc.c (gdb_make_enums_visible): New constant. This ports to
712 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
713 Zaretskii in <http://bugs.gnu.org/12036#13>.
714 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
715 needed now that we have gdb_make_enums_visible.

760 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
761 emacs.c, as this is a more-suitable home. Had this been done earlier
762 the fix for 12036 would have avoided some of the problems noted in
763 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
764 would have been more obvious.
765 * emacs.c: Do not include <verify.h>; no longer needed.
766 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
767 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)

774 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
775 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
776 not be usable in #if. This simplifies things.
778 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
780 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
782 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

785 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
786 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
787 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
788 Adjust to changes in lisp.h and emacs.c, by using
789 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
790 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
791 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
792 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
793 instead of gdb_valbits.
794 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
795 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
796 instead of gdb_array_mark_flag.
797 (xboolvector): Get size from $->size, not $->header.size.
798 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
799 (xreload, hook-run, hookpost-run): Remove.
800 * emacs.c: Include <verify.h>.
801 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
802 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
804 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
805 (gdb_USE_LSB_TAG): New enum constants.
806 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

809 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
810 as constants, so they're visible to GDB.
811 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
812 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
813 Now enum constants, not macros, so they're visible to GDB.
814 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
815 more convenient now. All uses changed.
816 (VALMASK) [USE_LSB_TAG]: Also define in this case.

827 add argument, tune behavior, and adjust all callers.
829 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
831 Use typedef for EMACS_INT, EMACS_UINT.
832 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
833 than macros. This simplifies debugging in the usual case, since
834 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
835 and it allows expressions involving EMACS_INT casts.
836 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
838 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

850 Adjust buffer text indirection counters at the end of Fkill_buffer.
851 * buffer.c (Fkill_buffer): Adjust indirection counters when the
852 buffer is definitely dead. This should really fix an issue reported
853 by Christoph Scholtes again. (Bug#12007).
854 (init_buffer_once): Initialize indirection counters of
855 buffer_defaults and buffer_local_symbols (for sanity and safety).
857 2012-07-24 Eli Zaretskii <eliz@gnu.org>
859 * xdisp.c (init_iterator): Don't compute dimensions of truncation
860 and continuation glyphs on tooltip frames, leave them at zero.
861 Avoids continued lines in tooltips. (Bug#11832)
863 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
865 Simplify copy_overlay.
866 * buffer.c (copy_overlay): Simplify. Use build_marker.

872 or invalid. (Bug#12025)
874 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
875 it signals an error when a tooltip frame is being created.
877 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

890 Swap buffer text indirection counters in Fbuffer_swap_text.
891 * buffer.c (Fbuffer_swap_text): Swap indirections too.
892 This avoids crash reported by Christoph Scholtes at
893 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
895 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
897 * nsmenu.m (Popdown_data): New struct.
898 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
900 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
901 (initWithContentRect): Make imgView and contentView non-static
902 and autorelease them. Also autorelease img and matrix (Bug#12005).

1651 * s/aix4-2.h (unix): Remove; no longer needed.
1653 EMACS_TIME simplification (Bug#11875).
1654 This replaces macros (which typically do not work in GDB)
1655 with functions, typedefs and enums, making the code easier to debug.
1656 The functional style also makes code easier to read and maintain.
1657 * systime.h: Include <sys/time.h> on all hosts, not just if
1658 WINDOWSNT, since 'struct timeval' is needed in general.

1671 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1672 not functions. All uses rewritten to use the following, respectively:
1673 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1674 (add_emacs_time, sub_emacs_time): New functions.
1675 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1696 * nsterm.m: Include <ftoastr.h>.
1698 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1699 Prefer snprintf to strncpy.
1700 * nsterm.m (ns_term_init):
1701 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1702 * nsterm.m (ns_term_init):
1703 Avoid the need for strncpy, by using build_string or
1704 make_unibyte_string directly. Use dtoastr, not snprintf.
1705 * process.c (Fmake_network_process): Diagnose service names that
1706 are too long, rather than silently truncating them or creating
1707 non-null-terminated names.
1708 (Fnetwork_interface_info): Likewise, for interface names.
1709 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1710 Prefer sprintf to strncat.

1717 Clarify fallback case.
1719 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

1724 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1725 where argument type is known to be a Lisp_Cons.

1741 the function is called with compile-time constant argument.
1742 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1743 argument, adjust users accordingly. Use build_pure_c_string where

1777 We include usg5-4-common.h, which defines them both.
1779 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1780 O_RDONLY already includes it).
1782 Stop ns builds setting the EMACSLOADPATH environment variable.
1783 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1784 Now it does not set EMACSLOADPATH, just returns the load-path string.
1785 * nsterm.h: Update accordingly.
1786 * lread.c [HAVE_NS]: Include nsterm.h.
1787 (init_lread) [HAVE_NS]: Use ns_load_path.

1790 2012-07-09 Glenn Morris <rgm@gnu.org>
1792 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,

1797 (ns_init_paths): Do not set EMACSPATH.
1798 * nsterm.h (ns_exec_path): Add it.
1799 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1802 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1804 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1806 * process.c (wait_reading_process_output): 'waitchannels' was unset

1828 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1830 Use make_formatted_string to avoid double length calculation.
1831 * lisp.h (make_formatted_string): New prototype.
1832 * alloc.c (make_formatted_string): New function.
1833 * buffer.c (Fgenerate_new_buffer_name): Use it.

1836 * filelock.c (get_boot_time): Likewise.
1837 * frame.c (make_terminal_frame, set_term_frame_name)
1838 (x_report_frame_params): Likewise.
1839 * image.c (gs_load): Likewise.

1851 * nsterm.h (ns_etc_directory): Add it.
1852 * callproc.c [HAVE_NS]: Include nsterm.h.
1853 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1855 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1857 Move marker debugging code under MARKER_DEBUG.
1858 * marker.c (MARKER_DEBUG): Move marker debugging code under
1859 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1860 for bootstrap with --enable-checking (~3x slowdown reported
1861 by Juanma Barranquero <lekktu@gmail.com>).
1862 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1864 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1866 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1867 See <http://bugs.gnu.org/11825#29>.
1869 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1871 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1872 has no font, use the frame's font. (Bug#11813)
1873 (display_line): Add commentary about displaying truncation glyphs
1875 (produce_special_glyphs): Move here from term.c.
1877 * term.c (produce_special_glyphs): Move to xdisp.c.
1879 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1882 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1884 * xdisp.c (display_line): Avoid warning about implicit declaration
1887 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1889 * lisp.h: Remove empty conditional.
1891 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1893 * lread.c (load_path_check): Now static.
1895 Fix some minor --with-ns problems found by static checking.
1896 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1897 (x_set_font) [!HAVE_X_WINDOWS]:
1898 * image.c (xpm_load_image) [HAVE_NS]:
1899 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1900 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1901 Remove unused local.
1902 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1903 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1904 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1905 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1906 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1907 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1908 Fix pointer signedness problem.
1909 * xfaces.c (FRAME_X_FONT_TABLE):
1910 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1912 2012-07-07 Glenn Morris <rgm@gnu.org>
1914 * lread.c (load_path_check): New function, split from init_lread.
1915 (init_lread): Reorganize. Motivation:
1916 If EMACSLOADPATH is set, check/warn about that rather than the
1917 defaults, which we are not going to use. Hence we can remove
1918 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1919 Don't warn if site-lisp directories are missing.
1920 If not installed, start from a blank load-path, since
1921 PATH_LOADSEARCH refers to the eventual installation directories.
1923 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1925 Support truncation and continuation glyphs on GUI frames, when
1926 fringes are disabled. (Bug#11832)
1927 * xdisp.c (init_iterator): Get dimensions of truncation and
1928 continuation glyphs even if on GUI frames. Adjust
1929 it->last_visible_x on GUI frames when the left or right fringes,
1930 or both, are absent.
1931 (start_display, move_it_in_display_line_to): Handle the case of a
1932 GUI frame without a fringe to display continuation or truncation
1934 (insert_left_trunc_glyphs): Support GUI frames: make sure
1935 truncation glyphs overwrite enough glyphs from the current line to
1936 have sufficient space in pixels.
1937 (display_line): Support truncation and continuation glyphs on GUI
1938 frames. If some spare pixels are left on the line after inserting
1939 the truncation glyphs, fill that space with a stretch glyph of a
1940 suitably computed width.
1942 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1943 produce_glyphs, to support GUI sessions.
1945 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1947 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1949 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1951 Do not require float-time's arg to fit in time_t (Bug#11825).
1952 This works better on hosts where time_t is unsigned, and where
1953 float-time is applied to the (negative) difference between two times.
1954 * editfns.c (decode_time_components): Last arg is now double *,
1955 not int *, and means to store all the result as a double, without
1956 worrying about whether the seconds part fits in time_t.
1957 All callers changed.
1958 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1959 All callers changed.
1960 (Ffloat_time): Do not fail merely because the specified time falls
1961 outside of time_t range.
1963 2012-07-07 Glenn Morris <rgm@gnu.org>
1965 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1971 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1972 Update dependencies.
1974 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1976 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1978 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1979 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1980 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1981 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1982 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1983 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1985 * xfont.c (compare_font_names): Redo to omit the need for casts.
1987 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1989 * xfns.c (Fx_change_window_property): Doc fix.
1990 * w32fns.c (Fx_change_window_property): Doc fix.
1992 * w32fns.c (Fx_window_property): Accept the same arguments as the
1993 X Windows version. Doc fix.
1994 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1996 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1997 Eli Zaretskii <eliz@gnu.org>
1999 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2000 Windows-specific code from nt/config.nt moved here.
2001 Obsolete settings removed.
2003 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2005 * process.c: Avoid unnecessary calls to gettime.
2006 (wait_reading_process_output): Don't get the time of day
2007 when gobbling data immediately and not waiting, as there's no need
2008 for it in that case. This removes a FIXME.
2010 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2012 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2013 is defined (Bug#11768).
2015 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2017 Fix marker debugging code.
2018 * marker.c (byte_char_debug_check): Do not perform the check
2019 if buffer is not multibyte.
2020 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2021 Call byte_char_debug_check with correct arguments.
2023 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2025 Compile marker debugging code only if ENABLE_CHECKING is defined.
2026 * marker.c (byte_char_debug_check, count_markers):
2027 Use only if ENABLE_CHECKING is defined.
2028 (byte_debug_flag): Remove.
2029 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2030 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2032 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2034 Avoid code repetition in marker-related functions.
2035 * marker.c (attach_marker): New function.
2036 (Fset_marker, set_marker_restricted, set_marker_both)
2037 (set_marker_restricted_both): Use it.
2038 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2039 Consistently rename charno to charpos.
2040 (marker_position): Add eassert.
2041 (marker_byte_position): Convert to eassert.

2056 * editfns.c (buildmark): Remove.
2057 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2058 (save_restriction_save): Use build_marker.
2059 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2060 * window.c (save_window_save): Likewise.
2062 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2064 Do not use Fdelete_overlay in delete_all_overlays
2065 to avoid redundant calls to unchain_overlay.
2066 * buffer.c (drop_overlay): New function.
2067 (delete_all_overlays, Fdelete_overlay): Use it.
2068 * minibuf.c (get_minibuffer): Fix comment.
2070 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2072 Port to OpenBSD 5.1 amd64.
2073 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2074 This is needed for OpenBSD, and should be harmless on all BSD systems.
2075 Also, include <sys/sysctl.h>, as it should be available on all
2076 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2077 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2078 use p_pid member, not kp_proc.pid.
2080 2012-07-06 Glenn Morris <rgm@gnu.org>
2082 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2084 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2086 More xmalloc and related cleanup.
2087 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2088 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

2093 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
2094 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
2095 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2097 Omit needless casts involving void * pointers and allocation.
2098 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2099 as the former is more robust if P's type is changed.
2100 Prefer xzalloc to xmalloc + memset 0.
2101 Simplify malloc-or-realloc to realloc.
2102 Don't worry about xmalloc returning a null pointer.
2103 Prefer xstrdup to xmalloc + strcpy.
2104 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2106 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2107 alloca of a constant.
2109 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2111 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2112 hscroll is larger than the line width. Fixes long and futile
2113 looping inside extend_face_to_end_of_line (on a TTY) producing
2114 glyphs that are not needed and thrown away.
2116 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2118 * marker.c (set_marker_restricted_both): Simplify by using
2121 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

2132 followed by gtk_box_set_homogeneous (Bug#11768).
2133 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2134 (update_theme_scrollbar_width, xg_create_scroll_bar):
2135 Use gtk_scrollbar_new (Bug#11768).
2136 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2137 (is_box_type): New function (Bug#11768).
2138 (xg_tool_item_stale_p): Call is_box_type.
2139 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2140 with default display (Bug#11768).
2142 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2144 * xdisp.c (window_hscroll_limited): New function.
2145 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2146 coordinates when window's hscroll is set to insanely large
2149 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2151 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2152 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

2218 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2219 This should be fixed in a better way; see Eli Zaretskii in
2220 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2221 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2223 * fileio.c (time_error_value): Rename from special_mtime.
2224 The old name's problems were noted by Eli Zaretskii in
2225 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2227 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2228 This variable's comment says Emacs needs at least one GDB-visible
2229 symbol of type enum pvec_type, to work around GDB problems.
2230 The symbol's value doesn't matter.
2232 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2233 that causes compilation to fail on pre-C99 compilers.
2235 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2237 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

2248 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2249 * lisp.h (enum pvec_type): Use fewer bits.
2250 (PSEUDOVECTOR_SIZE_BITS): New constant.
2251 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2252 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2253 change in pvec_type.
2254 (PSEUDOVECTOR_TYPEP): New macro.
2255 (TYPED_PSEUDOVECTORP): Use it.
2256 * fns.c (internal_equal): Adapt code to extract pvectype.
2257 * emacs.c (gdb_pvec_type): Update type.
2258 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
2259 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
2260 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2261 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2262 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2263 abusing vector->header.next.nbytes.
2264 (live_vector_p): Use PVEC_TYPE.
2265 (mark_object): Adapt code to extract pvectype. Use switch.
2267 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2269 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2270 Tighten new eassert a bit.
2272 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2274 Fix compilation with --enable-gcc-warnings and -O1
2276 * doprnt.c (doprnt): Change type of tem to int, initialize
2277 to avoid compiler warning. Add eassert.
2278 * search.c (simple_search): Initialize match_byte to avoid
2279 compiler warning. Add eassert.
2281 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2283 Avoid weird behavior with large horizontal scrolls.
2284 Without this change, for example, large hscroll values would
2285 mess up Emacs's display on Fedora 15 x86, presumably due to
2286 overflows in int calculations in the display code.
2287 Also, if buffers had long lines, Emacs would freeze.
2288 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2289 (set_window_hscroll): New function, containing the old guts of
2290 Fset_window_hscroll. Return the clipped value.
2291 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2292 This avoids the need to check against PTRDIFF_MAX.
2294 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2296 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2298 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2300 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2302 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2303 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2304 since GCC 4.4.6 issues a bogus warning for them.
2306 Fix bugs in file timestamp newness comparisons.
2307 * fileio.c (Ffile_newer_than_file_p):
2308 * lread.c (Fload): Use full timestamp resolution of files,
2309 not just the 1-second resolution, so that files that are only
2310 slightly newer still count as newer.
2311 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2312 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2314 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2316 * fileio.c: Improve handling of file time marker. (Bug#11852)
2317 (special_mtime): New function.
2318 (Finsert_file_contents, Fverify_visited_file_modtime):
2319 Use it to set special mtime values consistently.
2321 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2323 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2324 marker for non-existing file. (Bug#11852)
2326 2012-07-03 Glenn Morris <rgm@gnu.org>
2328 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2329 and did not make it into globals.h).
2331 2012-07-03 Tom Tromey <tromey@redhat.com>
2333 * window.c (Fset_window_margins, Fset_window_fringes)
2334 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2335 * textprop.c (Fprevious_property_change): No longer static.
2336 * syntax.c (Fsyntax_table_p): No longer static.

2352 * composite.c (Fcomposition_get_gstring): No longer static.
2353 * callproc.c (Fgetenv_internal): No longer static.

2365 * window.h: Remove EXFUNs.
2366 * xsettings.h: Remove EXFUN.
2367 * xterm.h: Remove EXFUN.
2369 2012-07-03 Glenn Morris <rgm@gnu.org>
2371 * lisp.h (Frandom): Make it visible to C.
2372 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2373 buffer for invisible buffers. (Bug#1229)
2375 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2377 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2378 values which aren't power of 2.
2379 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
2380 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2383 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2385 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2387 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2389 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2391 * alloc.c (allocate_vector_block): Remove redundant
2392 calls to mallopt if DOUG_LEA_MALLOC is defined.
2393 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2394 avoid calls to mallopt if zero_vector is returned.
2396 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2398 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2399 is enabled, avoid dereferencing NULL current_sblock if
2402 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2404 Cleanup basic buffer management.
2405 * buffer.h (struct buffer): Change layout to use generic vector
2406 marking code. Fix some comments. Change type of 'clip_changed'
2407 to bitfield. Remove unused #ifndef old.
2408 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2409 (GET_OVERLAYS_AT): Fix indentation.
2410 (for_each_per_buffer_object_at): New macro.
2411 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2412 (Fbuffer_local_variables): Use it.
2413 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2414 * alloc.c (allocate_buffer): Adjust to match new layout of
2415 struct buffer. Fix comment.
2416 (mark_overlay): New function.
2417 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2418 Lisp area of struct buffer.
2419 (mark_object): Use it. Adjust marking of misc objects
2420 and related comments.
2422 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2424 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2425 wrapper that is not needed because the wrapped code is a no-op (zero
2426 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2427 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2429 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2431 * alloc.c (mark_buffer): Simplify. Remove prototype.
2432 (mark_object): Add comment. Reorganize marking of vector-like
2433 objects. Use CHECK_LIVE for all vector-like objects except buffers
2434 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
2435 redundant calls to mark_vectorlike for bool vectors.
2437 2012-06-30 Glenn Morris <rgm@gnu.org>
2439 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2441 * epaths.in (PATH_SITELOADSEARCH): New.
2442 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2443 This is rather than relying on --enable-locallisppath elements
2444 having "site-lisp" in their names. (Bug#10208#25, 11658)
2446 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2448 * w32proc.c (sys_select): Accept and ignore one more argument.
2450 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2452 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2453 (pselect) [!MS_DOS]: Redirect to sys_select.
2455 * sysdep.c: Don't include dos.h and dosfns.h.
2457 * process.c (sys_select):
2458 * msdos.c (sys_select): Accept one more argument and ignore it.
2460 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2461 adapt data types and code to that.
2464 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2465 which clashes with the gnulib function of the same name.
2467 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2469 * font.c (font_style_to_value, font_style_symbolic)
2470 (font_prop_validate_style): Add type checks for values in
2473 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2475 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2478 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2480 * xdisp.c (try_window_id): Undo last change.
2482 * w32.c (getwd): Adjust commentary about startup_dir.
2483 (init_environment): Always call sys_access, even in non-MSVC
2484 builds. Don't chdir to the directory of the Emacs executable.
2485 This undoes code from 1997 which was justified by the need to
2486 "avoid conflicts when removing and renaming directories". But its
2487 downside was that every relative file name was being interpreted
2488 relative to the directory of the Emacs executable, which can never
2489 be TRT. In particular, it broke sys_access when called with
2490 relative file names.
2491 (sys_access): Map GetLastError to errno.
2493 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2495 * window.h (struct window): Change type of 'fringes_outside_margins'
2496 to bitfield. Fix comment. Adjust users accordingly.
2497 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2499 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2502 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2504 * gnutls.c (emacs_gnutls_handshake):
2505 Add QUIT to make the loop interruptible.
2507 2012-06-29 Glenn Morris <rgm@gnu.org>
2509 * charset.c (init_charset): Make lack of etc/charsets fatal.
2511 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2513 * editfns.c (region_limit): Fix type mismatch.
2515 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2517 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2518 undefined. Convert from xassert to eassert.
2519 * nsmenu.m: Convert from xassert to eassert.
2520 * nsterm.m: Likewise.
2522 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
2524 * editfns.c (region_limit): Clip to narrowing (bug#11770).
2526 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2528 Avoid integer overflow on scroll-left and scroll-right.
2529 * window.c (HSCROLL_MAX): New macro.
2530 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2531 overflow when requested scroll falls outside ptrdiff_t range.
2533 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2535 * window.h (struct window): Change type of 'hscroll',
2536 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2537 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2538 Adjust users accordingly.
2539 * xdisp.c (try_cursor_movement): Replace type check with eassert.
2540 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
2541 from EMACS_INT to ptrdiff_t.
2542 (make_window): Omit redundant initialization.
2544 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

2548 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2550 * window.h (struct window): Change type of 'use_time' and
2551 'sequence_number' from Lisp_Object to int.

2561 Fix GLYPH_DEBUG usage assuming that it may be undefined,
2562 adjust comments accordingly.

2612 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
2613 avoid GCC warning about unused macro.
2615 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2617 * alloc.c (allocate_string): Omit intervals initialization.
2618 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2619 as in make_pure_string and make_pure_c_string.
2621 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2623 * alloc.c (allocate_string): Fix last change.
2625 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2675 * alloc.c: Remove build_string.
2676 * lisp.h: Define build_string as static inline. This provides
2677 a better opportunity to optimize away calls to strlen when the
2678 function is called with compile-time constant argument.
2679 * image.c (imagemagick_error): Convert to build_string.
2680 * w32proc.c (sys_spawnve): Likewise.
2681 * xterm.c (x_term_init): Likewise.
2683 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2685 Use sprintf return value instead of invoking strlen on result.
2686 In the old days this wasn't portable, since some sprintf
2687 implementations returned char *. But they died out years ago and
2688 Emacs already assumes sprintf returns int.
2689 Similarly for float_to_string.
2690 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2691 * ccl.c (ccl_driver):
2692 * character.c (string_escape_byte8):

2695 * print.c (print_object):
2696 * xdisp.c (message_dolog):
2697 * xfns.c (syms_of_xfns):
2698 Use sprintf or float_to_string result to avoid need to call strlen.
2699 * data.c (Fnumber_to_string):
2700 Use make_unibyte_string, since the string must be ASCII.
2701 * lisp.h, print.c (float_to_string): Now returns int length.
2702 * term.c (produce_glyphless_glyph):
2703 Use sprintf result rather than recomputing it.
2705 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2706 * Makefile.in (ALL_CFLAGS):
2707 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2713 strcasecmp if available.

2738 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2741 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2743 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2744 instead of truncating it to 63 (admittedly a generous limit).
2746 * process.c: Fix spelling and caps in comments.
2748 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2750 * emacs.c (setpgrp): Remove definition, unused.

2762 * systime.h [WINDOWSNT]: Include sys/time.h.
2764 * s/ms-w32.h (struct timespec): Definition moved from
2765 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.

2874 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2876 Support higher-resolution time stamps (Bug#9000).
2877 The time stamps are only nanosecond-resolution at the C level,
2878 since that's the best that any real-world system supports now.
2879 But they are picosecond-resolution at the Lisp level, as that's
2880 easy, and leaves room for future OS improvements.
2882 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2885 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2886 Don't get current time unless it's needed.
2888 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2889 now provides it if it's absent.
2890 (start_atimer): Port to higher-res time stamps.
2891 Check for time stamp overflow. Don't get current time more
2892 often than is needed.
2894 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2895 Include systime.h, not time.h.
2896 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2898 * dired.c: Include stat-time.h.
2899 (Ffile-attributes): File times now have higher resolution.

2902 (struct image): Timestamp now has higher resolution.
2904 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2905 has at least microseconds now. All uses removed.
2906 (update_frame, update_single_window, update_window, update_frame_1)
2907 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2909 * editfns.c (time_overflow): Now extern.
2910 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

2915 (decode_time_components, lisp_seconds_argument): New functions.
2916 (make_time): Now static.
2917 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2918 Report an error if the time is invalid, rather than having the caller
2921 * fileio.c: Include <stat-time.h>
2922 (Fcopy_file): Copy higher-resolution time stamps.
2923 Prefer to set the time stamp via a file descriptor if that works.
2924 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2925 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2926 (Fvisited_file_modtime, Fset_visited_file_modtime):
2927 Support higher-resolution time stamps.
2929 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2931 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2933 * image.c (prepare_image_for_display, clear_image_cache)
2934 (lookup_image): Port to higer-resolution time stamps.
2936 * keyboard.c (start_polling, bind_polling_period):
2937 Check for time stamp overflow.
2938 (read_char, kbd_buffer_get_event, timer_start_idle)
2939 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2940 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2941 Port to higher-resolution time stamps. Do not assume time_t is signed.
2942 (decode_timer): New function. Timers are now vectors of length 9,
2943 not 8, to accommodate the picosecond component.
2944 (timer_check_2): Use it.
2946 * nsterm.m (select_timeout, timeval_subtract): Remove.
2947 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2948 as they're a bit more accurate and handle overflow better.
2949 (ns_select): Change prototype to be compatible with pselect.
2950 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2951 * nsterm.h (ns_select): Adjust prototype.
2953 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2954 us-resolution time stamps.
2955 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2957 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2959 * lisp.h (time_overflow): New decl.
2960 (wait_reading_process_output): First arg is now intmax_t, not int,
2961 to accommodate larger waits.
2963 * process.h (struct Lisp_Process.read_output_delay):
2964 Now counts nanoseconds, not microseconds.
2965 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2967 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2968 (wait_reading_process_output):
2969 Port to ns-resolution time stamps.
2970 (Faccept_process_output, wait_reading_process_output):
2971 Check for time stamp overflow. Do not assume time_t is signed.
2972 (select_wrapper): Remove; we now use pselect.
2973 (Fprocess_attributes): Now generates ns-resolution time stamps.
2975 * sysdep.c: Include utimens.h. Don't include utime.h
2976 or worry about struct utimbuf; gnulib does that for us now.
2977 (gettimeofday): Remove; gnulib provides a substitute.
2978 (make_timeval): New function.
2979 (set_file_times): Now sets ns-resolution time stamps.
2980 New arg FD; all uses changed.
2981 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2982 (system_process_attributes):
2983 Now returns ns-resolution time stamp. All uses changed.
2984 Check for time stamp overflow.
2986 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2987 provides a substitute now.
2989 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2990 since it guarantees struct timespec.
2991 (EMACS_TIME): Now struct timespec, so that we can support
2992 ns-resolution time stamps.
2993 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2994 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2995 (EMACS_USECS): Remove.
2996 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2997 so multiply the arg by 1000 before storing it.
2998 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3000 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3001 Port to ns-resolution time stamps.
3002 (EMACS_TIME_NEG_P): Remove; replaced by....
3003 (EMACS_TIME_SIGN): New macro.
3004 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3005 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3006 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3007 (make_timeval, make_lisp_time, decode_time_components): New decls.
3008 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3009 that it mishandled time_t overflow. You can't compare by subtracting!
3010 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3011 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3013 * term.c: Include <sys/time.h>.
3014 (timeval_to_Time): New function, for proper overflow wraparound.

3019 (Fprimitive_undo): Use them when restoring time stamps.
3021 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3022 (w32_get_internal_run_time):
3023 Port to higher-resolution Emacs time stamps.
3024 (ltime): Now accepts single 64-bit integer, as that's more convenient
3027 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3029 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3030 for compatibility with pselect. Support ns-resolution time stamps.
3032 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3034 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3035 Check for time stamp overflow, and support ns-resolution time stamps.
3037 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3038 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3039 (timeval_subtract): Remove; no longer needed.
3040 (XTflash, XTring_bell, x_wait_for_event):
3041 Port to ns-resolution time stamps. Don't assume time_t is signed.
3043 2012-06-22 Chong Yidong <cyd@gnu.org>

3047 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3049 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3050 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3051 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3052 staticidx goes up to 1597 out of 1600 = 0x640.)
3054 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3056 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3057 Otherwise, the umask might be mistakenly 0 while handling input signals.

3079 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3081 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3082 since tty frames can be explicitly named.
3083 (prepare_menu_bars): Likewise.

3091 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3092 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3093 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

3102 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3103 gets killed during executing of this function (Bug#11665).
3104 Try to always return Qt when the buffer has been actually killed.
3105 (Vkill_buffer_query_functions): In doc-string say that functions
3106 run by this hook should not change the current buffer.
3108 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3110 Fix recently-introduced process.c problems found by static checking.

3128 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3130 * lisp.h (eassert): Assume C89 or later.
3131 This removes the need for CHECK.
3132 (CHECK): Remove. Its comments about always evaluating its
3133 argument were confusing, as 'eassert' typically does not evaluate
3136 * coding.c (produce_chars): Use ptrdiff_t, not int.
3138 * xterm.c (x_draw_underwave): Check for integer overflow.
3139 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

3263 Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
3264 (INTTYPEBITS): New macro, for clarity.
3265 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
3266 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

3278 * s/usg5-4-common.h (USG5_4): No longer define; unused.
3280 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
3282 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
3285 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
3287 * emacs.c (gdb_use_struct): Rename from gdb_use_union.
3288 * .gdbinit: Check gdb_use_struct instead of gdb_use_union.
3289 * alloc.c (widen_to_Lisp_Object): Remove.

3291 * frame.c (delete_frame): Remove outdated comment.
3292 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
3293 USE_LISP_UNION_TYPE.

3310 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
3312 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
3313 * alloc.c (make_number) [!defined make_number]:
3314 Remove, as lisp.h always defines this now.
3315 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
3316 (roundup_size): Verify that it is a power of 2.
3317 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
3318 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
3319 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
3320 -DUSE_LSB_TAG=0, to override the automatically-selected default.
3321 USE_LSB_TAG now is always defined to be either 0 or 1.
3323 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3324 code works fine either way, and efficiency is not a concern here,
3325 as the union type is for debugging, not for production.
3326 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3327 Use an inline function on all platforms when using the union type,
3328 since this is simpler and 'static inline' can be used portably
3330 (LISP_INITIALLY_ZERO): New macro.
3331 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3332 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3359 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
3360 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
3361 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

3401 dbus_type_is_basic if available.
3402 (xd_extract_signed, xd_extract_unsigned): Rename from
3403 extract_signed and extract_unsigned, respectively. Adapt callers.
3405 2012-06-09 Chong Yidong <cyd@gnu.org>

3414 * xdisp.c (vmessage): Treat frame message as multibyte.
3415 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
3416 would generate the diagnostic "Making \302\247 buffer-local while
3419 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3421 * dispnew.c (showing_window_margins_p): Undo last change, which

3435 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
3437 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3439 * alloc.c (allocate_vectorlike): Fix last change.
3441 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
3443 Block-based vector allocation of small vectors.
3444 * lisp.h (struct vectorlike_header): New field `nbytes',
3445 adjust comment accordingly.

3470 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3472 * doprnt.c (doprnt): Truncate multibyte char correctly.
3473 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3474 would mishandle a string argument "Xc" if X was a multibyte
3475 character of length 2: it would truncate after X's first byte
3476 rather than including all of X.
3478 2012-06-06 Chong Yidong <cyd@gnu.org>
3480 * buffer.c (word_wrap): Doc fix.

3529 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3530 Convert pctcpu and pctmem to Lisp float properly.
3531 Let the compiler fold better, as 100.0/0x8000 is exact.
3533 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3535 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3538 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
3540 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
3542 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
3544 For a 'struct window', replace some Lisp_Object fields to
3545 bitfields where appropriate, remove unused fields.
3546 * window.h (struct window): Remove unused 'last_mark_x' and
3547 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
3548 change it's type from Lisp_Object to bitfield.
3549 Change type of 'force_start', 'optional_new_start',
3550 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
3551 fields from Lisp_Object to bitfield. Adjust users accordingly.
3553 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3555 Pacify gcc -Wdouble-precision when using Xaw.
3556 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
3557 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
3558 Use 'float' consistently, rather than 'float' in most places
3559 and 'double' in a couple of places.
3561 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3563 * xdisp.c (handle_stop): Detect whether we have overlay strings
3564 loaded by testing it->current.overlay_string_index to be
3565 non-negative, instead of checking whether n_overlay_strings is
3566 positive. (Bug#11587)
3568 2012-05-31 Chong Yidong <cyd@gnu.org>
3570 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
3572 * doc.c (Fsubstitute_command_keys): Doc fix.
3574 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3576 * search.c (search_buffer): Remove calls to
3577 r_alloc_inhibit_buffer_relocation, as it is now called by
3578 maybe_unify_char, which was the cause of relocation of buffer text
3581 2012-05-31 Eli Zaretskii <eliz@gnu.org>
3583 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
3584 for the duration of call to load_charset, to avoid problems with
3585 callers of maybe_unify_char that access buffer text through C
3588 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
3589 decrement the inhibition flag, instead of just setting or
3592 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
3594 Remove obsolete '#define static' cruft.
3595 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3596 This #undef was "temporary" in 2000; it is no longer needed
3597 now that '#define static' has gone away.
3598 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3599 (gray_bitmap_bits): Remove; no longer needed.
3600 All uses replaced with definiens.
3601 * xterm.c: Include "bitmaps/gray.xbm".
3603 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3605 Clean up __executable_start, monstartup when --enable-profiling.
3606 The following changes affect the code only when profiling.
3607 * dispnew.c (__executable_start): Rename from safe_bcopy.
3608 Define only on platforms that need it.
3609 * emacs.c: Include <sys/gmon.h> when profiling.
3610 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3611 (__executable_start): Remove decl, since lisp.h does it now.
3612 (safe_bcopy): Remove decl; no longer has that name.
3613 (main): Coalesce #if into single bit of code, for simplicity.
3614 Cast pointers to uintptr_t, since standard libraries want integers

3643 Do not create empty overlays with the evaporate property (Bug#9642).
3644 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3645 Bug#9642, but explicitly check that the buffer the overlay would
3646 be moved to is live and rearrange lines to make sure that errors
3647 will not put the overlay in an inconsistent state.
3648 (Fdelete_overlay): Cosmetics.
3650 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3652 * w32term.c (my_bring_window_to_top): New function.
3653 (x_raise_frame): Use handle returned by DeferWindowPos, which

3658 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3659 by calling BringWindowToTop.

3664 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3666 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3667 This avoids undefined behavior that might cause the eassert
3668 to not catch an out-of-range value.
3670 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3672 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3682 when referring to sectname field in printf format.
3684 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3686 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3687 Only r_alloc_inhibit_buffer_relocation needed to be added;
3688 the others were already declared.
3690 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3691 before checking whether it's out of range. Put the check inside
3693 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3695 2012-05-27 Ken Brown <kbrown@cornell.edu>
3697 * callproc.c (Fcall_process): Restore a line that was accidentally
3698 commented out in the 2011-02-13 change (bug#11547).

3702 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3703 defined on ralloc.c.
3705 * buffer.c [REL_ALLOC]: Remove prototypes of
3706 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3707 they are now on lisp.h.
3709 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3711 * search.c (search_buffer): Use it to inhibit relocation of buffer
3712 text while re_search_2 is doing its job, because re_search_2 is
3713 passed C pointers to buffer text. (Bug#11519)
3715 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3718 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3719 state after an additional call to move_it_in_display_line_to, keep
3720 the values of it->max_ascent and it->max_descent found for the
3722 (pos_visible_p): Revert the comparison against bottom_y to what it
3723 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3726 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3728 Fix coding-related core dumps with gcc -ftrapv.
3729 The code was computing A - B, where A and B are pointers, and B is
3730 random garbage. This can lead to core dumps on platforms that
3731 have special pointer registers, and it also leads to core dumps on
3732 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3733 A - B only when B is initialized properly.

3757 gen_help_event to produce help-echo message in the echo area.
3758 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3761 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3763 * lread.c (read1): Simplify slightly to avoid an overflow warning
3764 with GCC 4.7.0 on x86-64.
3766 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3768 * bidi.c (bidi_mirror_char): Revert last change: an int is
3769 definitely wide enough here.
3771 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3773 Fix integer width and related bugs (Bug#9874).

3785 Use int, not EMACS_INT, where int is wide enough.

3805 (Foverlay_recenter, last_overlay_modification_hooks_used)
3806 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3807 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3808 (validate_region): Omit unnecessary test for b <= e,
3809 since that's guaranteed by the previous test.
3810 (adjust_overlays_for_delete): Avoid pos + length overflow.
3811 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3812 (report_overlay_modification):

3814 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

3823 not int, to avoid needless 32-bit limit on 64-bit hosts.
3824 (exec_byte_code): Use tighter memory-full test, one that checks
3825 for alloca overflow. Don't compute the address of the object just
3826 before an array, as that's not portable. Use EMACS_INT, not
3827 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3828 * callint.c (Fcall_interactively):
3829 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3841 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3842 (casify_object): Avoid integer overflow when overallocating buffer.
3843 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3846 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3847 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

3850 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3851 For CCL_MapSingle, check that content and value are in int range.

3853 Check that Vcode_version_map_vector is a vector.
3854 (resolve_symbol_ccl_program): Check that vector header is in range.
3855 Always copy the vector, so that we can check its contents reliably
3856 now rather than having to recheck each instruction as it's being
3857 executed. Check that vector words fit in 'int'.
3858 (ccl_get_compiled_code, Fregister_ccl_program)
3859 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3860 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3862 contents are in range.
3863 (Fccl_execute_on_string): Check that status is in range.
3864 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3865 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3866 Accept and return EMACS_INT, not int, because callers can pass values

3872 (string_escape_byte8, Fget_byte):
3873 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3875 avoid mishandling large integers.
3876 * character.h: Adjust decls to match defn changes elsewhere.

3886 Don't rely on undefined behavior with signed left shift overflow.
3887 Don't assume unsigned int fits into fixnum, or that fixnum fits
3888 into unsigned int. Don't require max_code to be a valid fixnum;
3889 that's not true for gb10830 4-byte on a 32-bit host. Allow
3890 invalid_code to be a cons, for the same reason. Require code_offset
3891 to be a character. Avoid int overflow if max_char is close
3893 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3894 this is intended anyway and avoids some undefined behavior.
3895 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3896 INDEX_TO_CODE_POINT, as that's what it expects.
3897 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3898 * charset.h (DECODE_CHAR): Return int, not unsigned;
3899 this is what was intended anyway, and it avoids undefined behavior.
3900 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3901 integer-overflow issues.
3902 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3903 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3904 where the argument is EMACS_INT, and this behavior is not intended.
3905 * chartab.c (Fmake_char_table, Fset_char_table_range)
3906 (uniprop_get_decoder, uniprop_get_encoder):
3907 Don't assume fixnum fits in int.
3908 * cmds.c (move_point): New function, that does the gist of
3909 Fforward_char and Fbackward_char, but does so while checking
3910 for integer overflow more accurately.
3911 (Fforward_char, Fbackward_char): Use it.
3912 (Fforward_line, Fend_of_line, internal_self_insert)
3913 (internal_self_insert):
3914 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

4695 2012-05-14 Glenn Morris <rgm@gnu.org>
4697 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4698 Put "libexec" before "bin", for the sake of init_callproc_1.
4700 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4702 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

4705 (report_error, report_error_1, make_hdr, copy_sym)
4706 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4707 Make arguments const char *, not char *, to avoid violations of C
4708 standard and to fix some AIX warnings reported by Gilles Pion.
4710 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4712 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4713 already have overlays loaded.
4714 (handle_single_display_spec): Before returning without displaying
4715 fringe bitmap, synchronize the bidi iterator with the main display
4716 iterator, by calling iterate_out_of_display_property.
4717 (iterate_out_of_display_property): Detect buffer iteration by
4718 testing that it->string is a Lisp string.
4719 (get_next_display_element): When the current object is exhausted,
4720 and there's something on it->stack, call set_iterator_to_next to
4721 proceed with what's on the stack, instead of returning zero.
4722 (set_iterator_to_next): If called at the end of a Lisp string,
4723 proceed to consider_string_end without incrementing string
4724 position. Don't increment display vector index past the end of
4725 the display vector. (Bug#11417)
4726 (pos_visible_p): Don't report a position visible when move_it_to
4727 stopped at the last line of window, which happens to be scanned
4728 backwards by the bidi iteration. (Bug#11464)
4730 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4732 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4733 and right-margin display specs even if the spec is invalid or we
4734 are on a TTY, and thus unable to display on the fringes.
4735 That's because the text with the property will not be displayed anyway,
4736 so we need to signal to the caller that this is a "replacing"
4737 display spec. This fixes display when the spec is invalid or we
4740 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4742 * unexaix.c (make_hdr): Fix typo in prototype.
4743 This bug broke the build on AIX. Problem reported by Gilles Pion.
4745 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4747 * keyboard.c (kbd_buffer_get_event): Read special events also in
4748 batch mode. (Bug#11415)

4758 2012-05-12 Glenn Morris <rgm@gnu.org>
4760 * Makefile.in (MKDIR_P): New, set by configure.
4761 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4763 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>

4773 Update dependencies.
4775 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4777 * xgselect.c (xg_select): Put maxfds+1 into a var.
4778 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4780 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4782 2012-05-10 Dave Abrahams <dave@boostpro.com>
4784 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4785 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4787 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4789 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4790 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4791 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4792 Initialize xd_registered_buses.
4794 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4796 Untag more efficiently if USE_LSB_TAG.
4797 This is based on a proposal by YAMAMOTO Mitsuharu in
4798 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4799 For an admittedly artificial (nth 8000 longlist) benchmark on
4800 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4801 Emacs's overall text size by 1%.
4802 * lisp.h (XUNTAG): New macro.
4803 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4804 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4805 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4806 * eval.c (Fautoload):
4807 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4808 * frame.h (XFRAME): Use XUNTAG.
4810 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4811 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4812 Remove unportable assumptions about print widths of types like
4814 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4815 intptr_t when converting between pointer and integer, to avoid GCC
4816 warnings about wrong width.
4818 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4820 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4821 stack for each reader_thread, instead of defaulting to 8MB
4822 determined by the linker. This avoids failures in creating
4823 subprocesses on Windows 7, see the discussion in this thread:
4824 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4826 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4828 Fix up display of the *Minibuf-0* buffer in the mini window.
4829 * keyboard.c (read_char): Don't clear the echo area if there's no
4831 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4832 contents of *Minibuf-0*) if there's no message displayed in its stead.
4834 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4836 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4839 2012-05-06 Chong Yidong <cyd@gnu.org>
4841 * lisp.mk (lisp): Update.
4843 2012-05-05 Jim Meyering <meyering@redhat.com>
4845 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4847 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4849 * data.c (PUT_ERROR): New macro.
4850 (syms_of_data): Use it. Add new error type `user-error'.
4851 * undo.c (user_error): New function.
4852 (Fprimitive_undo): Use it.
4853 * print.c (print_error_message): Adjust print style for `user-error'.
4854 * keyboard.c (user_error): New function.
4855 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.

4859 Do not limit current-time-string to years 1000..9999.
4860 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4861 (Fcurrent_time_string): Support any year that is supported by the
4862 underlying localtime representation. Don't use asctime, as it
4863 has undefined behavior for years outside the range -999..9999.
4865 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4867 Fix race conditions involving setenv, gmtime, localtime, asctime.
4868 Without this fix, interrupts could mess up code that uses these
4869 nonreentrant functions, since setting TZ invalidates existing
4870 tm_zone or tzname values, and since most of these functions return
4871 pointers to static storage.
4872 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4873 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4874 Grow the critical sections to include not just invoking
4875 localtime/gmtime, but also accessing these functions' results
4876 including their tm_zone values if any, and any related TZ setting.
4877 (format_time_string): Last arg is now struct tm *, not struct tm **,
4878 so that the struct tm is saved in the critical section.
4879 All callers changed. Simplify allocation of initial buffer, partly
4880 motivated by the fact that memory allocation needs to be outside
4881 the critical section.
4883 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4885 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4886 with RESET_INTERVAL.
4888 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4889 Remove duplicated buffer name initialization.
4891 2012-05-02 Jim Meyering <jim@meyering.net>
4893 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4895 * xfns.c (x_window): Use xstrdup (Bug#11375).
4897 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4899 * xdisp.c (pos_visible_p): If already at a newline from the
4900 display string before the 'while' loop, don't walk back the glyphs
4901 from it3.glyph_row. Solves assertion violation when the display
4902 string begins with a newline (egg.el). (Bug#11367)
4904 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4906 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4909 2012-05-01 Glenn Morris <rgm@gnu.org>
4911 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4912 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4913 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4914 All were removed before 23.1.
4916 * dispnew.c: Remove HAVE_LIBNCURSES test;
4917 it is always true on relevant platforms.
4919 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4920 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4922 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4924 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4926 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4927 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4930 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4932 Do not avoid creating empty evaporating overlays (Bug#9642).
4933 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4934 That is, do not delete an evaporating overlay if it becomes
4935 empty after its bounds are adjusted to fit within its buffer.
4936 This fix caused other problems, and I'm reverting it until we get
4937 to the bottom of them.
4939 2012-04-27 Chong Yidong <cyd@gnu.org>
4941 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4943 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4945 * xdisp.c (pos_visible_p): If the window start position is beyond
4946 ZV, start the display from buffer beginning. Prevents assertion
4947 violation in init_iterator when the minibuffer window is scrolled
4950 * window.c (window_scroll_pixel_based): Likewise.
4952 2012-04-27 Chong Yidong <cyd@gnu.org>
4954 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4956 2012-04-27 Glenn Morris <rgm@gnu.org>
4958 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4959 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4961 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4963 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4964 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4966 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4968 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4969 display element, check also the underlying string or buffer
4970 character. (Bug#11341)
4972 * w32menu.c: Include w32heap.h.
4973 (add_menu_item): If the call to AppendMenuW (via
4974 unicode_append_menu) fails, disable Unicode menus only if we are
4975 running on Windows 9X/Me.
4977 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4979 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4980 (xgetint): Add missing shift for LSB tags.
4982 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4984 * keyboard.c (read_char): Don't wipe echo area for select window
4985 events: These might get delayed via `mouse-autoselect-window'
4988 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4990 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4991 manipulation of :loaded-from data.
4993 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4995 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4996 now a cons (bug#11311).
4998 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5000 Do not create empty overlays with the evaporate property (Bug#9642).
5001 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5002 if it becomes empty after its bounds are adjusted to fit within
5003 its buffer. Without this fix, in a nonempty buffer (let ((o
5004 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5005 yields an empty overlay that has the evaporate property, which is
5006 not supposed to happen.
5008 Fix minor GTK3 problems found by static checking.
5009 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5010 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5011 (struct _EmacsFixedClass, emacs_fixed_get_type):

5021 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5023 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5024 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5026 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5028 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5029 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5030 (__malloc_size_t, __malloc_ptrdiff_t):
5031 Remove. All uses removed, replaced by the definiens if needed,
5032 since we can assume C89 or better now.
5033 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

5043 Define using prototypes, not old style.
5044 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5045 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5046 (align): Don't assume that signed integer overflow wraps around.
5047 Omit unused local var.
5048 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

5108 * alloc.c: Handle unusual debugging option combinations.
5109 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5110 since the two debugging options are incompatible.
5111 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5113 (mem_init, mem_insert, mem_insert_fixup):
5114 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

5123 * sysdep.c [__FreeBSD__]: Minor cleanups.
5124 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5125 Use Emacs indenting style more consistently. Avoid some casts.
5126 Use 'double' consistently rather than mixing 'float' and 'double'.
5128 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5130 * sysdep.c (list_system_processes, system_process_attributes):
5131 Add implementation for FreeBSD (Bug#5243).

5144 * print.c (print_preprocess): Only check print_depth if print-circle
5146 (print_object): Check for cycles even when print-circle is nil and
5147 print-gensym is t, but only check print_depth if print-circle is nil.
5149 2012-04-20 Chong Yidong <cyd@gnu.org>
5151 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5152 set the status to "failed" and ensure that sentinel is run.

5167 farther than the first row after the header line, if any.
5168 Don't consider the header-line row as "partially visible", even if
5169 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

5207 New extern decls, to avoid calling undeclared functions.
5208 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5209 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5210 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5211 (NEED_MEM_INSERT): New macro.
5212 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5213 Remove one incorrect comment and fix another.

5227 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5228 Remove decls. This fixes an "It stinks!".
5230 * alloc.c (which_symbols): Fix alignment issue / type clash.
5232 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5234 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

5245 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5247 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5248 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5249 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5250 * s/netbsd.h, s/sol2-6.h:
5251 Remove definition of GC_MARK_STACK, since the default now works.
5252 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5253 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5254 no longer the default.
5255 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5257 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5259 * lread.c (lisp_file_lexically_bound_p):

5280 2012-04-11 Daniel Colascione <dancol@dancol.org>
5282 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5283 against is gone. It's better to use vfork now so that when Cygwin
5284 gains a new, working vfork, we use it automatically (bug#10398).
5286 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

5307 being loaded (bug#10424).
5309 2012-04-09 Glenn Morris <rgm@gnu.org>
5311 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5312 not just in the obarray, before snarfing them. (Bug#11036)
5314 * Makefile.in ($(leimdir)/leim-list.el):
5315 Pass EMACS rather than BUILT_EMACS.
5317 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5319 * process.c (make_process):
5320 * process.h: Add integer `gnutls_handshakes_tried' member to
5323 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5324 Add convenience `GNUTLS_LOG2i' macro.
5326 * gnutls.c (gnutls_log_function2i): Convenience log function.
5327 (emacs_gnutls_read): Use new log functions,
5328 `gnutls_handshakes_tried' process member, and
5329 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5330 attempts per process (connection).
5332 2012-04-09 Chong Yidong <cyd@gnu.org>
5334 * eval.c (Fuser_variable_p, user_variable_p_eh)

5339 * minibuf.c (Fread_variable): Callers changed.
5341 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5343 * xdisp.c (set_cursor_from_row): If the display string appears in
5344 the buffer at position that is closer to point than the position
5345 after the display string, display the cursor on the first glyph of
5346 the display string. Fixes cursor display when a 'display' text
5347 property immediately follows invisible text. (Bug#11094)
5349 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5351 composite.c: use 'double' consistently
5352 * composite.c (get_composition_id): Use 'double' consistently
5353 instead of converting 'float' to 'double' and vice versa; this is
5354 easier to understand and avoids a GCC warning.
5356 2012-04-09 Glenn Morris <rgm@gnu.org>
5358 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5359 preparation for dumping it with emacs. (Bug#4789)
5360 (leimdir): New variable.
5361 ($(leimdir)/leim-list.el): New rule.

5378 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5380 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5381 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5382 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5383 objects, as mark_maybe_pointer will catch them otherwise.
5384 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5385 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5387 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5389 Fix typo that broke non-Windows builds.
5390 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

5394 Support building on MS-Windows with libxml2.
5396 * makefile.w32-in (OBJ2): Add xml.$(O).
5397 (GLOBAL_SOURCES): Add xml.c.
5398 ($(BLD)/xml.$(O)): New dependency list.
5400 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5401 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5402 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5403 [!WINDOWSNT]: New macros.
5404 (init_libxml2_functions, libxml2_loaded_p): New functions.
5405 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5406 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5407 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5408 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5410 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5411 Call init_libxml2_functions before calling libxml2 functions.
5412 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5414 * emacs.c: Don't include libxml/parser.h.
5415 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5416 xmlCleanupParser directly.
5418 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5420 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5422 * indent.c (Fvertical_motion): If there is a display string at
5423 point, use it.vpos to compute how many lines to backtrack after
5424 move_it_to point. (Bug#11133)
5426 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5428 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5429 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5430 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5431 macros related to unification of CJK characters. For the details,
5432 see the discussion following the message here:
5433 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5435 2012-04-04 Chong Yidong <cyd@gnu.org>
5437 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5439 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5441 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5442 instead of alloca. (Bug#11138)
5444 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5446 * w32menu.c (is_simple_dialog): Properly check lisp types.
5449 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5451 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5452 position we get to after a call to move_it_to fails the
5453 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5454 only if we wind up in a string from display property. (Bug#11063)
5456 * window.c (Fdelete_other_windows_internal): Invalidate the row
5457 and column information about mouse highlight, so that redisplay
5458 restores it after reallocating the glyph matrices. (Bug#7464)
5460 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5461 string comes from a `display' text property, use the buffer
5462 position of that property as if we actually saw that position in
5464 (move_it_by_lines): Remove the assertion that
5465 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5466 violated when there's a before-string at the beginning of a line.
5469 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5471 * xdisp.c (append_space_for_newline): If the default face was
5472 remapped, use the remapped face for the appended newline.
5473 (extend_face_to_end_of_line): Use the remapped default face for
5474 extending the face to the end of the line.
5475 (display_line): Call extend_face_to_end_of_line when the default
5476 face was remapped. (Bug#11068)
5478 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5480 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5482 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5484 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5486 2012-03-27 Glenn Morris <rgm@gnu.org>
5488 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5491 2012-03-26 Kenichi Handa <handa@m17n.org>
5493 * dispextern.h (struct glyph): Fix previous change. Change the
5494 bit length of glyphless.ch to 25 (Bug#11082).
5496 2012-03-26 Chong Yidong <cyd@gnu.org>
5498 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5499 (command_loop_1): Use it; inhibit selection update for
5500 handle-select-window too (Bug#8996).
5502 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5504 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5506 2012-03-25 Kenichi Handa <handa@m17n.org>
5508 * dispextern.h (struct glyph): Change the bit length of
5509 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5511 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5513 * s/ms-w32.h (tzname): Include time.h before redirecting to
5514 _tzname. Fixes the MSVC build. (Bug#9960)
5516 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5518 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5521 * xterm.c (XTread_socket): Only modify handling_signal if
5522 !SYNC_INPUT. (Bug#11080)
5524 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5526 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5527 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5528 when fetching a multibyte character consumes more bytes than
5529 CHAR_BYTES returns, due to unification of CJK characters in
5530 string_char. (Bug#11073)
5532 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5534 * process.c (wait_reading_process_output): Handle pty disconnect
5535 by refraining from sending oneself a SIGCHLD (bug#10933).
5537 2012-03-22 Chong Yidong <cyd@gnu.org>
5539 * dispextern.h (struct it): New member string_from_prefix_prop_p.
5541 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
5542 Mark string as coming from a prefix property.
5543 (handle_face_prop): Use default face for prefix strings (Bug#4281).
5544 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
5546 2012-03-21 Chong Yidong <cyd@gnu.org>
5548 * xfaces.c (Vface_remapping_alist): Doc fix.
5550 2012-03-20 Eli Zaretskii <eliz@gnu.org>
5552 * w32proc.c (Fw32_set_console_codepage)
5553 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
5556 2012-03-20 Chong Yidong <cyd@gnu.org>
5558 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
5559 to reflect default non-nil value of redisplay-dont-pause.
5561 2012-03-19 Kenichi Handa <handa@m17n.org>
5563 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
5564 it fit in a valid range (Bug#11003).
5566 2012-03-18 Eli Zaretskii <eliz@gnu.org>
5568 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
5569 that is not from display property, accept the row as a "cursor
5570 row" if one of the string's character has a non-nil `cursor'
5571 property. Fixes cursor positioning when there are newlines in
5572 overlay strings, e.g. in icomplete.el. (Bug#11035)
5574 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
5576 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
5578 2012-03-12 Chong Yidong <cyd@gnu.org>
5580 * eval.c (inhibit_lisp_code): Rename from
5581 inhibit_window_configuration_change_hook; move from window.c.
5583 * xfns.c (unwind_create_frame_1, Fx_create_frame):
5584 * window.c (run_window_configuration_change_hook)
5585 (syms_of_window): Callers changed.
5587 2012-03-11 Chong Yidong <cyd@gnu.org>

5596 is visible (Bug#10955).
5598 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5600 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5602 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5604 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5605 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5608 2012-03-03 Glenn Morris <rgm@gnu.org>
5610 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5612 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5614 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5615 position past the first glyph_row that ends at ZV. (Bug#10902)
5616 (redisplay_window, next_element_from_string): Fix typos in
5618 (redisplay_window): Pass to move_it_vertically the margin in
5619 pixels, not in screen lines.
5621 2012-03-02 Glenn Morris <rgm@gnu.org>
5623 * buffer.c (buffer-list-update-hook): Doc fix.
5625 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5627 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5628 push_it before setting up the iterator for the first overlay
5629 string, even if we have an empty string loaded.
5630 (next_overlay_string): If there's an empty string on the iterator
5631 stack, pop the stack. (Bug#10903)
5633 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5635 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5636 Suggested by Stefan Monnier in
5637 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5638 * alloc.c (widen_to_Lisp_Object): New static function.
5639 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5640 and widening them to Lisp_Objects. This would work even if
5641 USE_LSB_TAG is defined and wide integers are used, which might
5642 happen in a future version of Emacs.
5644 2012-02-25 Chong Yidong <cyd@gnu.org>
5646 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5649 * xselect.c (Fx_selection_exists_p): Doc fix.
5650 (x_clipboard_manager_save_all): Print an informative message
5651 before saving to clipboard manager.
5653 2012-02-24 Chong Yidong <cyd@gnu.org>
5655 * keyboard.c (process_special_events): Handle all X selection
5656 requests in kbd_buffer, not just the next one (Bug#8869).
5658 2012-02-23 Chong Yidong <cyd@gnu.org>
5660 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5661 call when setting menu-bar-lines and tool-bar-lines parameters.
5662 (unwind_create_frame_1): New helper function.
5664 * window.c (inhibit_window_configuration_change_hook): New var.
5665 (run_window_configuration_change_hook): Obey it.
5666 (syms_of_window): Initialize it.
5668 2012-02-22 Chong Yidong <cyd@gnu.org>

5677 * buffer.c (Fget_file_buffer): Protect against invalid file
5678 handler return value.

5683 when computing $valmask.
5685 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5686 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5687 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5688 It's useless in that case, and it can cause problems on hosts
5689 that allocate halves of EMACS_INT values separately.
5690 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5691 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5692 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5693 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5694 it avoids undefined behavior on hosts where shifting right by more
5695 than the word width has undefined behavior.
5697 2012-02-19 Chong Yidong <cyd@gnu.org>
5699 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5700 (Funhandled_file_name_directory, Ffile_name_as_directory)
5701 (Fdirectory_file_name, Fexpand_file_name)
5702 (Fsubstitute_in_file_name): Protect against invalid file handler
5703 return values (Bug#10845).
5705 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5707 * .gdbinit (pitx): Fix incorrect references to fields of the
5710 2012-02-17 Chong Yidong <cyd@gnu.org>

5717 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5719 2012-02-15 Chong Yidong <cyd@gnu.org>
5721 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5722 marked as special. Also, starting docstrings with * is obsolete.
5724 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5726 * gnutls.c (emacs_gnutls_write): Fix last change.

5737 2012-02-12 Chong Yidong <cyd@gnu.org>
5739 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5740 as that creates a dangerous corner case.
5742 * window.c (Fdelete_window_internal): Invalidate the mouse
5743 highlight (Bug#9904).
5745 2012-02-12 Glenn Morris <rgm@gnu.org>
5747 * xselect.c (Fx_own_selection_internal)
5748 (Fx_get_selection_internal, Fx_disown_selection_internal)
5749 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5750 * nsselect.m (Fx_own_selection_internal)
5751 (Fx_disown_selection_internal, Fx_selection_exists_p)
5752 (Fx_selection_owner_p, Fx_get_selection_internal):
5753 Sync docs and argument specs with the xselect.c versions.
5755 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5757 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5759 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5761 * w32select.c (Fx_selection_exists_p): Sync doc string and
5762 argument list with xselect.c. (Bug#10783)

5775 2012-02-07 Chong Yidong <cyd@gnu.org>
5777 * buffer.c (Fbuffer_local_variables)
5778 (buffer_lisp_local_variables): Handle unbound vars correctly;
5779 don't let Qunbound leak into Lisp.
5781 2012-02-07 Glenn Morris <rgm@gnu.org>
5783 * image.c (Fimagemagick_types): Doc fix.
5785 * image.c (imagemagick-render-type): Change it from a lisp object
5786 to an integer. Move the doc here from the lisp manual.

5791 * doc.c (store_function_docstring): Avoid applying docstring of
5792 alias to base function (Bug#2603).

6347 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
6348 of scroll runs so as to avoid assigning disabled bogus rows and
6349 unnecessary graphics copy operations.
6351 2011-11-27 Eli Zaretskii <eliz@gnu.org>
6353 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

6356 (malloc, free, realloc, calloc): Redirect to e_* only when
6359 * lisp.h (GCTYPEBITS): Move before first use.
6360 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
6361 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
6362 this macro definition.
6364 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
6367 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

6385 Indent for consistency with usual Emacs style.
6387 2011-11-25 Eli Zaretskii <eliz@gnu.org>
6389 * xdisp.c (redisplay_window): If cursor row is not fully visible
6390 after recentering, and scroll-conservatively is set to a large
6391 number, scroll window by a few more lines to make the cursor fully
6392 visible and out of scroll-margin. (Bug#10105)
6393 (start_display): Don't move to the next line if the display should
6394 start at a newline that is part of a display vector or an overlay

6475 Otherwise, valgrind does not work on some platforms.
6476 Problem reported by Andreas Schwab in
6477 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
6478 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
6479 is set, removing the need for VIRT_ADDRESS_VARIES.
6480 (PURE_P): Use a more-efficient implementation that needs just one
6481 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
6482 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
6483 to 4 (xorl, subq, cmpq, setbe).
6484 * alloc.c (pure): Always extern now, since that's the
6485 VIRT_ADDR_VARIES behavior.
6486 (PURE_POINTER_P): Use a single comparison, not two, for
6487 consistency with the new puresize.h.
6488 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
6489 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

6495 (erase_phys_cursor, update_window_cursor, show_mouse_face)
6496 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6497 behave as if the cursor position were at the window margin.
6499 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6500 and the cursor position is out of bounds, behave as if the cursor
6501 position were at the window margin. (Bug#10075)
6503 2011-11-18 Chong Yidong <cyd@gnu.org>
6505 * window.c (Fwindow_combination_limit): Make first argument
6506 non-optional, since it is meaningless for live windows like the

6521 hash values of the two rows.
6522 (copy_row_except_pointers): Preserve the used[] arrays and the
6523 hash values of the two rows. (Bug#10035)
6524 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
6526 * xdisp.c (row_hash): New function, body extracted from
6527 compute_line_metrics.
6528 (compute_line_metrics): Call row_hash, instead of computing the
6531 * dispnew.c (verify_row_hash): Call row_hash for computing the
6532 hash code of a row, instead of duplicating code from xdisp.c.
6534 * dispextern.h (row_hash): Add prototype.
6536 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6538 * frame.c (delete_frame): Don't delete the terminal when the last
6539 X frame is closed if emacs is built with GTK toolkit.

6562 (Vwindow_nest): Rename to Vwindow_combination_limit.
6563 (recombine_windows, make_parent_window, make_window)
6564 (Fsplit_window_internal, saved_window)
6565 (Fset_window_configuration, save_window_save): Rename all
6566 occurrences of window_nest to window_combination_limit.
6568 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
6570 * image.c (imagemagick_load_image): Fix typo.
6572 2011-11-14 Eli Zaretskii <eliz@gnu.org>
6574 * xdisp.c (display_line): Move the call to
6575 highlight_trailing_whitespace before the call to
6576 compute_line_metrics, since the latter needs to see the final
6577 faces of all the glyphs to compute ROW's hash value.
6578 Fixes assertion violations in row_equal_p. (Bug#10035)
6580 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
6582 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

6587 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
6588 with user-defined heap size. Bump the default size of the temacs
6589 heap to 27MB, to avoid memory warning when running temacs.
6590 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6592 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6639 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6641 Avoid some portability problems by eschewing 'extern inline' functions.
6642 The trivial performance wins aren't worth the portability hassles; see
6643 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6645 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6646 (window_box_width, window_box_left, window_box_left_offset)
6647 (window_box_right, window_box_right_offset): Undo previous change,
6648 by removing the "extern"s.
6649 * intervals.c (adjust_intervals_for_insertion)
6650 (adjust_intervals_for_deletion): Undo previous change,
6651 making these static again.
6652 (offset_intervals, temp_set_point_both, temp_set_point)
6653 (copy_intervals_to_string): No longer inline.
6654 * xdisp.c (window_text_bottom_y, window_box_width)

6691 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
6693 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6694 This is also needed for porting to any host where GC_MARK_STACK is
6695 not GC_MAKE_GCPROS_NOOPS.
6696 (which_symbols): Use it.
6698 2011-11-07 Kenichi Handa <handa@m17n.org>

6711 * xmenu.c (cleanup_widget_value_tree): New function.
6712 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6719 (window_box_width, window_box_left, window_box_left_offset)
6720 (window_box_right, window_box_right_offset): Declare extern.
6721 Otherwise, these inline functions do not conform to C99 and
6722 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6723 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6724 * intervals.c (adjust_intervals_for_insertion)
6725 (adjust_intervals_for_deletion): Now extern, because otherwise the
6726 extern inline functions 'offset_intervals' couldn't refer to it.
6727 (static_offset_intervals): Remove.
6728 (offset_intervals): Rewrite using the old contents of
6729 static_offset_intervals. The old version didn't conform to C99
6730 because an extern inline function contained a reference to an
6731 identifier with static linkage.
6733 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6735 * keyboard.c (interrupt_signal): Don't call kill-emacs while in
6738 2011-11-06 Eli Zaretskii <eliz@gnu.org>

6750 (Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
6751 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
6752 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
6753 (Fwindow_vscroll): Doc fix.
6754 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6755 argument, since it makes no sense to pass a live window and for
6756 consistency with window-child.

6866 (mouse_face_from_buffer_pos, note_mouse_highlight):
6867 Rename cover_string to disp_string.
6869 2011-11-01 Martin Rudalics <rudalics@gmx.at>

6906 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6908 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6910 2011-10-29 Eli Zaretskii <eliz@gnu.org>

6929 Not clear what it was for, and it causes various bugs. (Bug#9839)
6931 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6933 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6934 possible random value that matches one of those tested as
6935 condition to clear the mouse face.
6937 2011-10-28 Chong Yidong <cyd@gnu.org>
6939 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

6959 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6960 (g_b_init_get_glyph_outline_w): New static variables.
6961 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)

6963 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6964 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6966 (w32font_open_internal, compute_metrics):
6967 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6968 instead of calling the "wide" APIs directly.
6970 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6972 * w32.h (syms_of_w32font): Add prototype.
6974 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6976 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)

7010 * w32fns.c (w32_default_color_map): New function,
7011 extracted from Fw32_default_color_map.
7012 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
7014 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
7016 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
7018 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
7020 * keyboard.c (test_undefined): New function (bug#9751).
7021 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
7023 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
7025 * sysdep.c (init_sys_modes): Fix the check for the controlling
7026 terminal (Bug#6649).
7028 2011-10-20 Eli Zaretskii <eliz@gnu.org>
7030 * dispextern.h (struct bidi_it): New member next_en_type.
7032 * bidi.c (bidi_line_init): Initialize the next_en_type member.
7033 (bidi_resolve_explicit_1): When next_en_pos is valid for the
7034 current character, check also for next_en_type being WEAK_EN.
7035 (bidi_resolve_weak): Don't enter the expensive loop if the current
7036 position is before next_en_pos. Record the bidi type of the first
7037 non-ET, non-BN character we find, in addition to its position.
7038 (bidi_level_of_next_char): Invalidate next_en_type when
7039 next_en_pos is over-stepped.
7041 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
7043 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7044 * editfns.c: Rewrite current-time-zone so that it invokes
7045 the equivalent of (format-time-string "%Z") to get the time zone name.
7046 This fixes a bug when the time zone name contains characters that
7047 need converting from the system time locale to Emacs internal format.
7048 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7049 that patch fixed format-time-string to do the conversion, but
7050 I forgot to fix current-time-zone.
7051 (format_time_string): New function, containing most of
7052 what Fformat_time_string used to contain.
7053 (Fformat_time_string): Rewrite in terms of format_time_string.
7054 This doesn't change this function's behavior.
7055 (current-time-zone): Rewrite to use format_time_string.
7056 This fixes the bug reported by Michael Schierl in
7057 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7058 Jason Rumney's 2007-06-07 change worked around this bug, but
7060 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7062 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7064 * xdisp.c (start_display): If the character at POS is displayed
7065 via a display vector, reset IT->current.dpvec_index to zero.
7066 (try_window_reusing_current_matrix): If a line ends in a display
7067 vector or the next line starts in a display vector, continue
7068 redrawing the window even though the character position of
7069 start_row was reached.
7072 2011-10-18 Chong Yidong <cyd@gnu.org>
7074 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7075 with nobreak-char-display too.
7077 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7079 Fix part 3 of bug#9771.
7080 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7081 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7082 non-neutral characters if the current character is a paragraph
7083 separator (a.k.a. Newline). This avoids running the same
7084 expensive loop twice, once when we consume the preceding newline
7085 and the other time when the line actually needs to be displayed.
7086 Avoid the loop when we see neutrals on the base embedding level
7087 following a character whose directionality is the same as the
7088 paragraph's. This avoids running the expensive loop when a line
7089 ends in a long sequence of neutrals, like control characters.
7090 Add assertion against STRONG_AL type. Slightly rearrange code
7091 that determines the type of a neutral given the first non-neutral
7093 (bidi_level_of_next_char): Set next_en_pos to zero when
7094 invalidating its info.
7096 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7098 * xdisp.c (push_display_prop): Determine whether to record string
7099 or buffer position by IT->string, not by IT->method. Allow
7100 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7101 (move_it_vertically_backward): Don't look for character position
7102 immediately after the newline when in a continuation line.
7105 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7107 * window.c (coordinates_in_window): Rewrite and delabelize
7108 vertical border check. (Bug#5357) (Bug#9618)
7110 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7112 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7113 errors in XSetWindowBorder (bug#9310).
7115 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7117 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7118 avoid crash when xmalloc overrun checking is enabled.
7120 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7122 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7123 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7124 cursor motion with <left> and <right> arrow keys.
7126 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7127 some callers set that themselves.
7129 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7131 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7132 display string and the previous row comes from the same string and
7133 is empty. (Bug#9739) (Bug#9738)
7135 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7137 * doc.c (get_doc_string): Encode file name (bug#9735).
7139 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7141 * bidi.c (bidi_level_of_next_char):
7142 * xdisp.c (get_visually_first_element): Remove old incorrect
7143 comments regarding the Unicode Line Separator character.
7145 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7147 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7149 * alloc.c (Fgc_status): Do not access beyond zombies array
7150 boundary if nzombies > MAX_ZOMBIES.
7151 * alloc.c (dump_zombies): Add missing format specifier.
7153 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7155 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7156 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7158 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7159 Some packages use them to denote characters with modifiers.
7161 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7163 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7164 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7165 matching a pp-number. Rename parameter var to var1.
7167 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7169 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7171 2011-10-08 Glenn Morris <rgm@gnu.org>
7173 * callint.c (Fcall_interactively): Give a more explicit error for the
7174 'c' case with a non-character input. (Bug#8479)
7176 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7178 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7180 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7181 lines that are hscrolled on the left.
7183 * dispnew.c (buffer_posn_from_coords): Account for a possible
7184 presence of header-line. (Bug#4426)
7186 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7188 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7189 Don't advertise functionality which we discourage or doesn't work.
7191 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7193 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7194 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7195 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7196 this makes Emacs dump core during garbage collection on rare
7197 occasions. sizeof is obviously inferior to offsetof here, so
7198 stick with offsetof.
7199 (GC_POINTER_ALIGNMENT): New macro.
7200 (mark_memory): Omit 3rd (offset) arg; caller changed.
7201 Don't assume EMACS_INT alignment is the same as pointer alignment.
7203 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7205 * keyboard.c (read_key_sequence_remapped): New var.
7206 (read_key_sequence): Compute remapping in the right buffer.
7207 (command_loop_1): Use read_key_sequence's remapping directly.
7209 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7211 * dired.c (file_name_completion): Don't expand file name.
7212 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7213 before checking file name handler.
7215 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7216 they've been requested explicitly (bug#9591).
7218 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7220 * keymap.c (Fsingle_key_description): Use make_specified_string
7221 instead of build_string to build string from push_key_description.
7224 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7226 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7227 This fixes a Y2038 bug on 64-bit hosts.
7228 * buffer.c (reset_buffer):
7229 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7230 (Fclear_buffer_auto_save_failure):
7231 Use 0, not -1, to represent an unset failure time, since time_t
7232 might not be signed.
7234 Remove dependency on glibc malloc internals.
7235 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7236 Move back here from lisp.h, but with their new implementations.
7237 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7238 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7239 * charset.c (charset_table_init): New static var.
7240 (syms_of_charset): Use it instead of xmalloc. This removes a
7241 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7242 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7243 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7244 Move back to alloc.c.
7245 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7246 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7248 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7250 * nsterm.m (windowDidResize): Call x_set_window_size only when
7251 ns_in_resize is true. Otherwise set pixelwidth/height and
7252 call change_frame_size (Bug#9628).
7254 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7256 Port --enable-checking=all to Fedora 14 x86-64.
7257 * charset.c (syms_of_charset): Also account for glibc malloc's
7258 internal overhead when calculating the initial malloc maximum.
7260 Port --enable-checking=all to Fedora 14 x86.
7261 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7263 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7264 (overrun_check_realloc, overrun_check_free):
7265 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7266 That way, xmalloc returns a properly-aligned pointer even if
7267 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7268 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7269 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7270 into account when calculating the initial malloc maximum.
7271 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7272 Move here from alloc.c, so that charset.c can use it too.
7273 Properly align; the old code wasn't right for common 32-bit hosts
7274 when configured with --enable-checking=all.
7275 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7276 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7278 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7280 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7283 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7285 * xdisp.c (compute_display_string_end): If there's no display
7286 string at CHARPOS, return -1.
7288 * bidi.c (bidi_fetch_char): When compute_display_string_end
7289 returns a negative value, treat the character as a normal
7290 character not covered by a display string. (Bug#9624)
7292 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7294 * lread.c (Fread_from_string): Fix typo in docstring.
7296 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7298 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7299 newline, reseat the iterator instead of bidi-iterating there one
7300 character at a time. (Bug#9610)
7301 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7302 TO_CHARPOS if the bidi iterator is at base embedding level.
7304 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7306 * lread.c (readevalloop): Use correct code for NBSP.
7307 (read1): Likewise. (Bug#9608)
7309 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7311 * dbusbind.c (Fdbus_register_signal): When service is not
7312 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7314 2011-09-25 Glenn Morris <rgm@gnu.org>
7316 * buffer.c (truncate-lines): Doc fix.
7318 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7320 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7321 (Fset_window_next_buffers): Doc fix.
7323 2011-09-24 Glenn Morris <rgm@gnu.org>
7325 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7327 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7329 Fix minor problems found by static checking.
7330 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7331 * indent.c (Fvertical_motion): Fix == vs = typo.
7333 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7335 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7336 Default value is now t. Doc fix.
7338 * indent.c (Fvertical_motion): Compute and apply the overshoot
7339 logic when moving up, not only when moving down. Fix the
7340 confusing name and values of the it_overshoot_expected variable;
7341 logic changes accordingly. (Bug#9254) (Bug#9549)
7343 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7344 CHARPOS is covered by a display string which includes newlines.
7345 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7346 is covered by a display string with embedded newlines.
7348 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7350 * dbusbind.c (Fdbus_register_signal): Add match rule to
7351 Vdbus_registered_objects_table. (Bug#9581)
7352 (Fdbus_register_method, Vdbus_registered_objects_table):
7355 2011-09-24 Jim Meyering <meyering@redhat.com>
7357 do not ignore write error for any output size
7358 The previous change was incomplete.
7359 While it makes emacs --batch detect the vast majority of stdout
7360 write failures, errors were still ignored whenever the output size is
7361 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7362 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7363 && echo FAIL: ignored write error
7364 FAIL: ignored write error
7365 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7366 && echo FAIL: ignored write error
7367 FAIL: ignored write error
7368 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7370 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7372 * emacs.c (Fkill_emacs): In noninteractive mode exit
7373 non-successfully if a write error occurred on stdout. (Bug#9574)
7375 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7377 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7380 * dispextern.h (struct it): Update the comment documenting what
7383 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7385 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7386 a display string, extend search for cursor position to end of row.
7387 (find_row_edges): If the row ends in a newline from a display
7388 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7389 Handle the case of a display string with multiple newlines.
7390 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7391 non-empty line. Fixes confusing cursor motion with arrow keys at
7392 the beginning of a line that starts with whitespace.
7394 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7396 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7399 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7401 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7404 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7406 * xdisp.c (display_line): Record maximum and minimum buffer
7407 positions even if no glyphs were produced (e.g., by a zero-width
7408 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7409 buffer positions that will be removed from the glyph row because
7411 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7412 column is beyond frame width: don't subtract 1 "pixel" when
7413 computing width of the stretch.
7414 (reseat_at_next_visible_line_start): Undo the change made on
7415 2011-09-17 that saved paragraph information and restored it after
7416 the call to `reseat'. (Bug#9545)
7418 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7420 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7421 and turn window cursor on if cleared (Bug#9415).
7423 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7425 * search.c (boyer_moore): Take unibyte characters from pattern
7426 literally. (Bug#9458)
7428 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7430 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7432 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7434 Fix minor problem found by static checking.
7435 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7436 initialized, to pacify gcc -Wuninitialized.
7438 * fileio.c: Report proper errno when syscall falls.
7439 (Finsert_file_contents): Save and restore errno,
7440 so that report_file_error outputs the correct diagnostic.
7441 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7443 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7445 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7447 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7449 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7450 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7452 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7454 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7455 about the current paragraph and restore it after the call to reseat.
7457 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7458 (bidi_find_paragraph_start): Search back for paragraph beginning
7459 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7460 (bidi_move_to_visually_next): Only trigger paragraph-related
7461 computations when the last character is a newline or at EOB, not
7462 just any NEUTRAL_B. (Bug#9470)
7464 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7465 truncated lines if point is covered by a display string. (Bug#9524)
7467 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7469 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7470 (cons_to_x_long): New function.
7471 (lisp_data_to_selection_data): Use it. Correct the test for
7472 short-versus-long data; it was negated. Break out of vector
7473 loop, for efficiency, when a long datum is discovered.
7475 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7477 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7479 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7481 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7482 GCC PR/17406) by declaring this function with external scope.
7484 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7486 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7487 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7489 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7491 * editfns.c (Fformat): Correctly handle text properties on "%%".

7501 of TAB characters in a composition.
7503 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7505 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7506 This occurs when processing a multibyte format.
7507 Problem reported by Wolfgang Jenker.
7509 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7511 * xdisp.c (try_cursor_movement): Only check for exact match if
7512 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7514 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7516 Remove unused external symbols.
7517 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7518 * xdisp.c (calc_pixel_width_or_height): Now static.
7519 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7520 * indent.c (check_display_width):
7521 * w32term.c: Fix comment to match code.
7522 * xterm.c, xterm.h (x_catching_errors): Remove.
7524 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7526 * xselect.c: Use signed conversions more consistently (Bug#9498).
7527 (selection_data_to_lisp_data): Assume incoming selection data are
7528 signed integers, not unsigned. This is to be consistent with
7529 outgoing selection data, which was modified to use signed integers
7530 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7531 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7532 expects long, not unsigned long.
7534 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7536 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7537 computation of loop end. Reported by Johan Bockgård
7540 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
7542 * frame.c (Fother_visible_frames_p): Function deleted.
7544 2011-09-12 Eli Zaretskii <eliz@gnu.org>
7546 * indent.c (compute_motion): Process display vector front to back
7547 rather than the other way around. (Bug#2496)
7549 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7551 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
7553 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7555 * minibuf.c (Fread_from_minibuffer): Doc fix.
7557 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7559 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
7560 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
7562 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
7564 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
7565 value for non-existent files.
7567 2011-09-11 Eli Zaretskii <eliz@gnu.org>
7569 * fileio.c (Finsert_file_contents): If the file cannot be opened,
7570 set its "size" to -1. This will set the modtime_size field of
7571 the corresponding buffer to -1, which is what
7572 verify-visited-file-modtime expects for files that do not exist.
7575 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
7577 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
7579 * lisp.h: ... from here. push_key_description is no longer
7580 defined in keyboard.c, so its declaration should not be in
7581 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
7582 logically belongs with push_key_description.
7584 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
7586 * buffer.h: Include <sys/types.h> instead of <time.h>.
7587 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
7588 Problem reported by Herbert J. Skuhra.
7590 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7592 * xml.c (parse_region): Make the parsing work for
7593 non-comment-starting XML files again (bug#9144).
7595 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7597 * image.c (gif_load): Fix calculation of bottom and right corner.
7600 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7602 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7603 redisplay in small windows.
7605 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7607 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7609 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7611 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7612 Operate on live windows only.
7614 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7616 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7618 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7620 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7621 only under bidi iteration.
7623 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7625 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7627 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7629 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7630 Without this fix, the command to link temacs failed due to an
7631 undefined symbol __builtin_isnan. This is because
7632 /usr/include/iso/math_c99.h #defines isnan(x) to
7633 __builtin_isnan(x), but the bundled gcc, which identifies itself
7634 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7636 * floatfns.c (isnan): #undef, and then #define to a clone of
7638 (Fisnan): Always define, since it's always available now.
7639 (syms_of_floatfns): Always define isnan at the Lisp level.
7641 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7643 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7645 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7647 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7648 The previous code assumed that file offsets (off_t values) fit in
7649 EMACS_INT variables, which is not true on typical 32-bit hosts.
7650 The code messed up by falsely reporting buffer overflow in cases
7651 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7652 when "big" contains more than 2**29 bytes, even though this
7653 inserts just one byte and does not overflow the buffer.
7654 (Finsert_file_contents): Store file offsets as off_t
7655 values, not as EMACS_INT values. Check for overflow when
7656 converting between EMACS_INT and off_t. When checking for
7657 buffer overflow or for overlap, take the offsets into account.
7658 Don't use EMACS_INT for small values where int suffices.
7659 When checking for overlap, fix a typo: ZV was used where
7660 ZV_BYTE was intended.
7661 (Fwrite_region): Don't assume off_t fits into 'long'.
7662 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7664 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7666 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7668 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7670 sprintf-related integer and memory overflow issues (Bug#9412).
7672 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7673 (esprintf, exprintf, evxprintf): New functions.
7674 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7675 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7676 (modify_event_symbol): Do not assume that the length of
7677 name_alist_or_stem is safe to alloca and fits in int.
7678 (Fexecute_extended_command): Likewise for function name and binding.
7679 (Frecursion_depth): Wrap around reliably on integer overflow.
7680 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7681 since some callers pass EMACS_INT values.
7682 (Fsingle_key_description): Don't crash if symbol name contains more
7683 than MAX_ALLOCA bytes.
7684 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7685 (get_minibuffer): Arg is now EMACS_INT, not int.
7686 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7687 (esprintf, exprintf, evxprintf): New decls.
7688 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7690 * dbusbind.c (signature_cat): New function.
7691 (xd_signature, Fdbus_register_signal):
7692 Do not overrun buffer; instead, report string overflow.
7694 * dispnew.c (add_window_display_history): Don't overrun buffer.
7695 Truncate instead; this is OK since it's just a log.
7697 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7698 even if the time zone offset is outlandishly large.
7699 Don't mishandle offset == INT_MIN.
7701 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7702 when creating daemon; the previous buffer-overflow check was incorrect.
7704 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7705 which has the guts of the old verror function.
7707 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7708 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7710 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7711 (font_unparse_xlfd): Don't blindly alloca long strings.
7712 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7713 fits in int, when using sprintf. Use single snprintf to count
7714 length of string rather than counting it via multiple sprintfs;
7715 that's simpler and more reliable.
7716 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7717 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7718 sprintf, in case result does not fit in int.
7720 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7721 (fontset_from_font): Print it.
7723 * frame.c (tty_frame_count): Now printmax_t, not int.
7724 (make_terminal_frame, set_term_frame_name): Print it.
7725 (x_report_frame_params): In X, window IDs are unsigned long,
7726 not signed long, so print them as unsigned.
7727 (validate_x_resource_name): Check for implausibly long names,
7728 and don't assume name length fits in 'int'.
7729 (x_get_resource_string): Don't blindly alloca invocation name;
7730 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7733 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7734 (xg_check_special_colors, xg_set_geometry):
7735 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7737 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7738 Use esprintf, not sprintf, in case result does not fit in int.
7740 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7741 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7742 it as a large positive number.
7743 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7744 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7746 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7747 in case result does not fit in int.
7749 * print.c (float_to_string): Detect width overflow more reliably.
7750 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7751 buffer overrun. Don't assume list length fits in 'int'. Treat
7752 print length of 0 as 0, not as infinity; to be consistent with other
7753 uses of print length in this function. Don't overflow print length
7754 index. Don't assume hash table size fits in 'long', or that
7755 vectorlike size fits in 'unsigned long'.
7757 * process.c (make_process): Use printmax_t, not int, to format
7758 process-name gensyms.
7760 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7762 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7763 to avoid potential buffer overrun.
7765 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7766 if X resource line is longer than 512 bytes.
7768 * xfns.c (x_window): Make sprintf buffer a bit bigger
7769 to avoid potential buffer overrun.
7771 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

7775 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7777 Integer overflow fixes for scrolling, etc.
7778 Without these, Emacs silently mishandles large integers sometimes.
7779 For example, "C-u 4294967297 M-x recenter" was treated as if
7780 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7782 * xdisp.c (try_window_id): Check Emacs fixnum range before
7783 converting to 'int'.
7785 * window.c (window_scroll_line_based, Frecenter):
7786 Check that an Emacs fixnum is in range before assigning it to 'int'.
7787 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7788 values converted from Emacs fixnums.
7789 (Frecenter): Don't wrap around a line count if it is out of 'int'
7790 range; instead, treat it as an extreme value.
7791 (Fset_window_configuration, compare_window_configurations):
7792 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7794 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7795 that can exceed INT_MAX. Check that EMACS_INT value is in range
7796 before assigning it to the (possibly-narrower) index.
7797 (match_limit): Don't assume that a fixnum can fit in 'int'.
7799 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7802 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7803 (Fvertical_motion): Don't wrap around LINES values that don't fit
7804 in 'int'. Instead, treat them as extreme values. This is good
7805 enough for windows, which can't have more than INT_MAX lines anyway.
7807 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7809 * Require libxml/parser.h to avoid compilation warning.
7811 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7813 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7814 since this reportedly can destroy thread storage.
7816 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7818 * syntax.c (find_defun_start): Update all cache variables if
7819 exiting early (Bug#9401).
7821 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7823 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7825 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7826 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7827 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7829 * term.c (tty_append_glyph): New function.
7830 (produce_stretch_glyph): Static function and its prototype deleted.
7832 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7835 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7837 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7838 when checking :margin (Bug#9390).
7839 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7840 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7841 so that the name doesn't mislead. All uses changed.
7843 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7845 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7848 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7850 * xdisp.c (move_it_to): Don't bail out early when reaching
7851 position beyond to_charpos, if we are scanning backwards.
7852 (move_it_vertically_backward): When DY == 0, make sure we get to
7853 the first character in the line after the newline.
7855 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7857 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7858 (ccl_driver): Do not generate an out-of-range pointer.
7859 (Fccl_execute_on_string): Remove unnecessary check for
7860 integer overflow, noted by Stefan Monnier in
7861 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7862 Remove a FIXME that didn't need fixing.
7863 Simplify the newly-introduced buffer reallocation code.
7865 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7867 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7869 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7871 Integer and memory overflow issues (Bug#9196).
7873 * doc.c (get_doc_string): Rework so that
7874 get_doc_string_buffer_size is the actual buffer size, rather than
7875 being 1 less than the actual buffer size; this makes xpalloc more
7878 * image.c (x_allocate_bitmap_record, cache_image):
7879 * xselect.c (Fx_register_dnd_atom):
7880 Simplify previous changes by using xpalloc.
7882 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7883 since either will do and ptrdiff_t is convenient with xpalloc.
7885 * charset.c (charset_table_size)
7886 (struct charset_sort_data.priority): Now ptrdiff_t.
7887 (charset_compare): Don't overflow if priorities differ greatly.
7888 (Fsort_charsets): Don't assume list length fits in int.
7889 Check for size-calculation overflow when allocating sort data.
7890 (syms_of_charset): Allocate an initial charset table that is
7891 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7893 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7895 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7896 The actual value is always <= INT_MAX, and leaving it unsigned made
7897 overflow checking harder.
7899 * dispextern.h (struct glyph_matrix.rows_allocated)
7900 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7901 with xpalloc. The values are still always <= INT_MAX.
7903 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7905 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7906 (SAFE_NALLOCA): New macro.
7908 * region-cache.c (struct boundary.pos, find_cache_boundary)
7909 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7910 (set_cache_region, invalidate_region_cache)
7911 (revalidate_region_cache, know_region_cache, region_cache_forward)
7912 (region_cache_backward, pp_cache):
7913 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7914 so that ptrdiff_t * can be passed to xpalloc.
7915 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7916 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7917 (pp_cache): Don't assume cache_len fits in int.
7918 * region-cache.h: Adjust extern decls to match.
7920 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7921 EMACS_INT, since either will do, for xpalloc.
7923 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7924 (xnmalloc, xnrealloc, xpalloc): New functions.
7926 * bidi.c (bidi_shelve_header_size): New constant.
7927 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7928 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7930 * bidi.c (bidi_cache_shrink):
7931 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7933 Don't update size of array until after memory allocation succeeds,
7934 because xmalloc/xrealloc may not return.
7935 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7936 now that we have proper integer overflow checking.
7937 (record_overlay_string, overlay_strings): Catch overflows when
7938 calculating size of overlay_str_buf.
7940 * callproc.c (Fcall_process): Check for size overflow when
7941 calculating size of args2.
7942 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7943 Normally we prefer signed values, but sticking with ptrdiff_t would
7944 require adding more-complicated checks.
7946 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7947 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7948 Redo buffer-overflow calculations to avoid integer overflow.
7949 Add a FIXME comment where memory seems to be over-allocated.
7951 * character.c (Fstring): Check for size-calculation overflow.
7953 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7954 unnecessary integer overflow. Check for size overflow.
7955 (encode_coding_object): Don't update size until xmalloc succeeds.
7957 * composite.c (get_composition_id): Check for overflow in glyph
7958 length calculations.
7960 Integer and memory overflow fixes for display code.
7961 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7962 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7963 (scrolling_window): Check for overflow in size calculations.
7964 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7975 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7976 (get_doc_string): Check for size calculation overflow.
7977 Don't update size until allocation succeeds.
7978 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7979 EMACS_INT, where ptrdiff_t will do.
7980 (Fsubstitute_command_keys): Check for string overflow.
7982 * editfns.c (set_time_zone_rule): Don't assume environment length
7984 (message_length): Now ptrdiff_t, not int.
7985 (Fmessage_box): Don't update size until allocation succeeds.
7986 Don't assume message length fits in int.
7987 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7989 * emacs.c (main): Do not reallocate argv, since there is a null at
7990 the end that can be overwritten, and this way there's no need to
7991 worry about size-calculation overflow.
7992 (sort_args): Check for size-calculation overflow.
7994 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7996 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7998 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7999 (x_set_scroll_bar_width, x_figure_window_size):
8000 Check for integer overflow.
8001 (x_set_alpha): Do not assume XINT fits in int.
8003 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8004 This is for the members text_lines, text_cols, total_lines, total_cols,
8005 where the system imposes an 'int' limit.
8007 * fringe.c (Fdefine_fringe_bitmap):
8008 Don't update size until alloc works.
8010 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
8011 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
8013 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
8014 Check for size-calculation overflow.
8015 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8016 do, as we prefer signed integers.
8017 (id_to_widget.max_size, id_to_widget.used)
8018 (xg_store_widget_in_map, xg_remove_widget_from_map)
8019 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
8020 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
8021 Use and return ptrdiff_t, not int.
8022 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
8023 * gtkutil.h: Change prototypes to match the above.
8025 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
8026 are duplicate now that they've been promoted to lisp.h.
8027 (x_allocate_bitmap_record, x_alloc_image_color)
8028 (make_image_cache, cache_image, xpm_load):
8029 Don't update size until alloc is done.
8030 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
8032 Check for size calculation overflow.
8033 (ct_colors_allocated_max): New constant.
8034 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

8039 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
8040 Use ptrdiff_t, not int, to count maps.
8041 (read_char_minibuf_menu_prompt): Check for overflow in size
8042 calculations. Don't update size until allocation succeeds.

8054 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
8056 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
8057 Now ptrdiff_t, not int.
8058 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

8069 * search.c (Freplace_match): Check for size calculation overflow.
8070 (Fset_match_data): Don't assume list lengths fit in 'int'.
8072 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8073 for command line length. Do not attempt to address one before the
8074 beginning of an array, as that's not portable.

8077 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
8079 (encode_terminal_code, calculate_costs): Check for size
8080 calculation overflow.

8082 table lengths and related sizes. Don't update size until alloc
8083 done. Redo calculations to avoid overflow.
8084 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
8086 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

8102 Use ptrdiff_t, not int, for sizes.
8103 (Finternal_make_lisp_face, cache_face):
8104 Check for size calculation overflow.
8105 (cache_face): Treat size calculation overflows as if they were
8106 memory exhaustion (the usual treatment), rather than aborting.
8108 * xfns.c (x_encode_text, x_set_name_internal)
8109 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8110 sizes, since they can exceed INT_MAX in size. Check for size
8111 calculation overflow.
8113 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8114 (xg_select): Check for size calculation overflow.
8115 Don't update size until alloc done.
8117 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8118 as sprintf is limited to int lengths.
8120 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8121 (X_LONG_MIN): New macros.
8122 Use them to make the following changes clearer.
8123 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8124 This change doesn't affect the value now, but it may help remind
8125 future maintainers not to raise the value too much later.
8126 (SELECTION_QUANTUM): Remove, replacing with ...
8127 (selection_quantum): ... new function, which avoids overflow.
8129 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8130 assumption that selection length fits in 'int'.
8131 (x_reply_selection_request, x_handle_selection_request)
8132 (x_get_window_property, receive_incremental_selection)
8133 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
8134 (lisp_data_to_selection_data, clean_local_selection_data):

8136 (x_reply_selection_request, x_get_window_property)
8137 (receive_incremental_selection, x_property_data_to_lisp):
8138 Redo calculations to avoid overflow.
8139 (x_reply_selection_request): When sending hint, ceiling it at
8140 X_LONG_MAX rather than relying on wraparound overflow to send
8142 (x_get_window_property, receive_incremental_selection)
8143 (lisp_data_to_selection_data, x_property_data_to_lisp):
8144 Check for size-calculation overflow.
8145 (x_get_window_property, receive_incremental_selection)

8147 Don't store size until memory allocation succeeds.
8148 (x_get_window_property): Plug memory leak on memory exhaustion.
8149 Don't double-block input; malloc is safe here. Don't assume 2**34
8150 - 4 fits in unsigned long. Add an xassert to check
8151 XGetWindowProperty overflow. Be more careful about overflow
8152 calculations, and distinguish size from memory overflow better.
8153 (receive_incremental_selection): When tracing, don't assume
8154 unsigned int is less than INT_MAX.
8155 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8156 harmful) conversions of unsigned short to int.
8157 (lisp_data_to_selection_data): Don't assume that integers
8158 in the range -65535 through -1 fit in an X unsigned short.
8159 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8160 result parameters unless successful. Rely on cons_to_unsigned
8161 to report problems with elements; the old code wasn't right anyway.
8162 (x_check_property_data): Check for int overflow; we cannot use
8163 a wider type due to X limits.
8164 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

8195 * image.c (xpm_get_color_table_h):
8196 * lisp.h (hash_lookup, hash_put):
8197 * minibuf.c (Ftest_completion):
8198 Use ptrdiff_t for hash table indexes, not int (which is too
8199 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8200 32-bit --with-wide-int hosts).
8202 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8203 Add a FIXME comment about memory leaks.
8204 (syms_of_charset): Don't assume xmalloc returns.
8206 Don't assume that stated character widths fit in int.
8207 * character.c (Fchar_width, c_string_width, lisp_string_width):
8208 * character.h (CHAR_WIDTH):
8209 * indent.c (MULTIBYTE_BYTES_WIDTH):
8210 Use sanitize_char_width to avoid undefined and/or bad behavior
8211 with outlandish widths.
8212 * character.h (sanitize_tab_width): Rename from sanitize_width,
8213 now that we have two such functions. All uses changed.
8214 (sanitize_char_width): New inline function.

8224 * fileio.c: Integer overflow issues with file modes.
8225 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.

8232 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
8233 (x_send_scroll_bar_event): Likewise. Check that the size does not
8234 exceed limits imposed by XClientMessageEvent, as well as the usual
8235 ptrdiff_t and size_t limits.
8237 * keyboard.c: Overflow, signedness and related fixes.
8238 (make_lispy_movement): Use same integer type in forward decl
8239 that is used in the definition.
8240 (read_key_sequence, keyremap_step):
8241 Change bufsize argument back to int, undoing my 2011-03-30 change.
8242 We prefer signed types, and int is wide enough here.
8243 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8244 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8245 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8246 length, not size_t. Use ptrdiff_t for index, not int.
8247 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8248 possibility of integer overflow.
8250 Overflow, signedness and related fixes for images.

8271 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8272 (lookup_image): Remove unnecessary tests.
8273 (xbm_image_p): Locals are now of int, not EMACS_INT,
8274 since parse_image_check makes sure they fit into int.
8275 (png_load, gif_load, svg_load_image):
8276 Prefer int to unsigned where either will do.
8277 (tiff_handler): New function, combining the cores of the
8278 old tiff_error_handler and tiff_warning_handler.
8279 This function is rewritten to use vsnprintf and thereby avoid
8280 stack buffer overflows. It uses only the features of vsnprintf
8281 that are common to both POSIX and native Microsoft.
8282 (tiff_error_handler, tiff_warning_handler): Use it.
8283 (tiff_load, gif_load, imagemagick_load_image):
8284 Don't assume :index value fits in 'int'.
8285 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8286 (imagemagick_load_image): Check that crop parameters fit into
8287 the integer types that MagickCropImage accepts. Don't assume
8288 Vimagemagick_render_type has a nonnegative value. Don't assume
8289 size_t fits in 'long'.
8290 (gs_load): Use printmax_t to print the widest integers possible.

8300 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8301 the display spec is of the form `(space ...)'.
8302 (handle_display_spec): Return the value returned by
8303 handle_single_display_spec, not just 1 or zero.
8304 (handle_single_display_spec): If the display spec is of the form
8305 `(space ...)', and specifies display in the text area, return 2
8307 (try_cursor_movement): Check for the need to scroll more
8308 accurately, and prefer exact match for point under bidi.
8309 Don't advance `row' beyond the last row of the window.
8311 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8312 into disp_prop; all users changed.
8314 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8326 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
8327 buffers, return left-to-right.
8328 (set_cursor_from_row): Consider candidate row a win if its glyph
8329 represents a newline and point is on that newline. Fixes cursor
8330 positioning on the newline at EOL of R2L text within L2R
8331 paragraph, and vice versa.
8332 (try_cursor_movement): Check continued rows, in addition to
8333 continuation rows. Fixes unwarranted scroll when point enters a
8334 continued line of R2L text within an L2R paragraph, or vice versa.
8335 (cursor_row_p): Consider the case of point being equal to
8336 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8337 from the end of a short line to the beginning of a continued line
8338 of R2L text within L2R paragraph.
8339 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
8340 composed characters.
8342 * bidi.c (bidi_check_type): Use xassert.
8343 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p

8355 2011-08-22 Kenichi Handa <handa@m17n.org>
8357 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
8358 extra slot even if the purpose is char-code-property-table.
8360 2011-08-23 Eli Zaretskii <eliz@gnu.org>
8362 * xdisp.c (redisplay_window): When computing centering_position,
8363 account for the height of the header line. (Bug#8874)
8365 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8366 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8367 candidate is selected by the mouse, and that candidate has a
8368 composed character under the mouse.
8370 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8371 coordinates reported by pos-visible-in-window-p for a composed
8372 character in column zero.
8374 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
8376 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
8378 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8380 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8381 consider it a hit if to_charpos is anywhere in the range of the
8382 composed buffer positions.
8384 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8386 * image.c (gif_load): Don't assume that each subimage has the same
8387 dimensions as the base image. Handle disposal method that is
8388 "undefined" by the gif spec (Bug#9335).
8390 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8392 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8393 (Fcondition_case): Document `debug' symbol in error handler.
8395 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8397 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8398 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8399 from an Org mode buffer to a Speedbar frame.
8401 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8402 a composition, take its buffer position from IT->cmp_it.charpos.
8403 Fixes cursor positioning at the beginning of a line that begins
8404 with a composed character.
8406 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8408 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8409 character bidirectional type, use STRONG_L instead. Fixes crashes
8410 in a buffer produced by `describe-categories'.
8412 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8413 members before the level stack, so they would be saved and
8414 restored when copying iterator state. Fixes incorrect reordering
8415 around TABs covered by display properties.
8417 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8419 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8424 (internal_condition_case_2, internal_condition_case_n):
8425 Remove unnecessary aborts (Bug#9081).
8427 2011-08-17 Eli Zaretskii <eliz@gnu.org>
8429 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
8430 has no `load' handler, try opening the file locally. (Bug#9311)
8432 2011-08-16 Ken Brown <kbrown@cornell.edu>

8489 * xdisp.c (move_it_in_display_line_to): Don't invoke
8490 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8491 ppos_it. Fixes vertical cursor motion when line beginning is
8492 covered by an image. (Bug#9296)
8494 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8496 * nsterm.h (ns_run_ascript): Declare.

8499 * nsfns.m (as_script, as_result, as_status): New static variables.
8500 (ns_run_ascript): New function.
8501 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8502 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8503 the event loop. Get status from as_status (Bug#7276).
8505 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8506 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8507 the event loop (Bug#7276).

8533 (Fnetwork_interface_list): Allocate in increments of bytes instead
8534 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8535 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8537 (struct ifflag_def): notrailers is smart on OSX.
8538 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8539 Get hardware address with getifaddrs if available.
8541 2011-08-12 Eli Zaretskii <eliz@gnu.org>
8543 * xdisp.c (iterate_out_of_display_property): xassert that
8544 IT->position is set to within IT->object's boundaries. Break from
8545 the loop as soon as EOB is reached; avoids infloops in redisplay
8546 when IT->position is set up wrongly due to some bug.
8547 Set IT->current to match the bidi iterator unconditionally.
8548 (push_display_prop): Allow GET_FROM_STRING as IT->method on
8549 entry. Force push_it to save on the stack the current
8550 buffer/string position, to be restored by pop_it. Fix flags in
8551 the iterator structure wrt the object coming from a display
8552 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
8553 properties. (Bug#9284)
8555 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
8557 * fontset.c (fontset_get_font_group): Add proper type checks.

8565 (dump_it) [LC_FUNCTION_STARTS]: Use it.
8567 2011-08-08 Eli Zaretskii <eliz@gnu.org>
8569 * xdisp.c (forward_to_next_line_start): Allow to use the
8570 no-display-properties-and-no-overlays under bidi display.
8571 Set disp_pos in the bidi iterator to avoid searches for display
8572 properties and overlays.
8574 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
8576 * editfns.c (Fset_time_zone_rule): Document relationship with the

8582 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
8584 * composite.c (autocmp_chars): Don't reset point. That is done by
8585 restore_point_unwind (Bug#5984).
8587 2011-08-07 Juri Linkov <juri@jurta.org>
8589 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
8590 to show the arg `TIME' instead of `TIMEVAL'.
8592 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8594 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8595 display property strides EOL and includes a newline, as in
8596 longlines-mode. (Bug#9254)
8597 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8598 word-wrap under bidirectional display. (Bug#9224)
8600 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8601 is non-zero, even if the data buffer is NULL. Fixes a crash in
8602 vertical-motion with longlines-mode. (Bug#9254)
8604 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8606 * bidi.c <bidi_cache_total_alloc>: Now static.
8607 (bidi_initialize): Initialize bidi_cache_total_alloc.
8609 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8612 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8613 amount allocated this far in `bidi_cache_total_alloc'.
8614 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8615 non-zero, only free the data buffer without restoring the cache
8616 contents. All callers changed.
8618 * dispextern.h (bidi_unshelve_cache): Update prototype.
8620 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8621 (move_it_in_display_line, move_it_to)
8622 (move_it_vertically_backward, move_it_by_lines): Replace the call
8623 to xfree to an equivalent call to bidi_unshelve_cache.
8624 (move_it_in_display_line_to): Fix logic of returning
8625 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8627 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8629 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8630 came from a string character with a `cursor' property. (Bug#9229)
8632 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8634 * Makefile.in (LIB_PTHREAD): New variable.

8649 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8651 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8653 * callproc.c (Fcall_process): Avoid vfork clobbering
8654 the local vars buffer, coding_systems, current_dir.
8656 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8658 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8660 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8662 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8663 so that it is not optimized away.
8665 * xdisp.c (compute_display_string_pos): Remove unused local.
8667 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8669 Fix slow cursor motion and scrolling in large buffers with
8670 selective display, like Org Mode buffers. (Bug#9218)
8672 * dispextern.h (struct bidi_it): New member disp_prop_p.
8674 * xdisp.c: Remove one-slot cache of display string positions.
8675 (compute_display_string_pos): Accept an additional argument
8676 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8677 for a display string or property. If found, set DISP_PROP_P
8680 * bidi.c (bidi_fetch_char): Accept an additional argument
8681 DISP_PROP_P, and pass it to compute_display_string_pos.
8682 Only handle text covered by a display string if DISP_PROP_P is returned
8683 non-zero. All callers of bidi_fetch_char changed.
8685 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8687 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8689 2010-12-03 Don March <don@ohspite.net>
8691 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8692 last character M-[char] is translated to ESC [char] (bug#7541).
8694 2011-08-02 Kenichi Handa <handa@m17n.org>
8696 * lisp.h (uniprop_table): Extern it.
8698 * chartab.c (uniprop_table): Make it non-static.
8700 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8702 * xdisp.c (forward_to_next_line_start): Accept additional argument
8703 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8705 (reseat_at_next_visible_line_start): Use the bidi iterator state
8706 returned by forward_to_next_line_start to restore the state of
8707 it->bidi_it after backing up to previous newline. (Bug#9212)
8709 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8711 * regex.c (re_comp): Protoize.
8712 (re_exec): Fix return type.
8713 (regexec): Fix type of `ret'. (Bug#9203)
8715 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8717 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8718 This is needed if max-image-size is a floating-point number.
8720 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8722 * print.c (print_object): Print empty symbol as ##.
8724 * lread.c (read1): Read ## as empty symbol.
8726 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8728 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8729 setting frame foreground color (Bug#9175).
8730 (x_set_background_color): Likewise.
8732 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8733 contents (Bug#9176).
8734 (EmacsTooltip -init): Remove bezels and add shadows to
8737 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8738 or scroll bar (Bug#8470).
8740 * nsfont.m (nsfont_open): Remove assignment to voffset and
8741 unnecessary vars hshink, expand, hd, full_height, min_height.
8742 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8744 * nsterm.h (nsfont_info): Remove voffset field.
8746 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8748 Implement strike-through and overline on NextStep (Bug#8863).
8750 * nsfont.m (nsfont_open): Use underline position provided by font,
8751 instead of hard-coded value of 2.
8752 (nsfont_draw): Call ns_draw_text_decoration instead.
8754 * nsterm.h: Add declaration for ns_draw_text_decoration.
8756 * nsterm.m (ns_draw_text_decoration): New function for drawing
8757 underline, overline, and strike-through.
8758 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8759 ns_draw_text_decoration. Change treatment of cursor drawing to
8760 accommodate underlining, etc.
8762 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8764 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8767 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8769 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8770 Without this fix, if a signal arrives just after memory fills up,
8771 'malloc' might be invoked reentrantly.
8773 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8774 In other words, assume that every image size is allowed, on non-X
8775 hosts. This assumption is probably wrong, but it lets Emacs compile.
8777 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8779 * regex.c (re_iswctype): Convert return values to boolean.
8781 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8783 * xdisp.c (compute_display_string_pos): Don't use cached display
8784 string position if the buffer had its restriction changed.
8787 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8789 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8791 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8793 Integer signedness and overflow and related fixes. (Bug#9079)
8795 * bidi.c: Integer size and overflow fixes.
8796 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8797 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8798 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8799 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8800 (bidi_find_other_level_edge):
8801 Use ptrdiff_t instead of EMACS_INT where either will do.
8802 This works better on 32-bit hosts configured --with-wide-int.
8803 (bidi_cache_ensure_space): Check for size-calculation overflow.
8804 Use % rather than repeated addition, for better worst-case speed.
8805 Don't set bidi_cache_size until after xrealloc returns, because it
8807 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8808 (bidi_cache_ensure_space): Also check that the bidi cache size
8809 does not exceed that of the largest Lisp string or buffer. See Eli
8810 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8812 * alloc.c (__malloc_size_t): Remove.
8813 All uses replaced by size_t. See Andreas Schwab's note
8814 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8816 * image.c: Improve checking for integer overflow.
8817 (check_image_size): Assume that f is nonnull, since
8818 it is always nonnull in practice. This is one less thing to
8819 worry about when checking for integer overflow later.
8820 (x_check_image_size): New function, which checks for integer
8821 overflow issues inside X.
8822 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8823 This removes the need for a memory_full check.
8824 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8825 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8826 (xbm_read_bitmap_data): Change locals back to 'int', since
8827 their values must fit in 'int'.
8828 (xpm_load_image, png_load, tiff_load):
8829 Invoke x_create_x_image_and_pixmap earlier,
8830 to avoid much needless work if the image is too large.
8831 (tiff_load): Treat overly large images as if
8832 x_create_x_image_and_pixmap failed, not as malloc failures.
8833 (gs_load): Use x_check_image_size.
8835 * gtkutil.c: Omit integer casts.
8836 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8837 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8839 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8841 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8842 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8843 would wrongly return t on a 64-bit host.
8845 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8846 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8847 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8848 and therefore cause GCC to emit a bogus diagnostic in some cases.
8850 * image.c: Integer signedness and overflow and related fixes.
8851 This is not an exhaustive set of fixes, but it's time to
8852 record what I've got.
8853 (lookup_pixel_color, check_image_size): Remove redundant decls.
8854 (check_image_size): Don't assume that arbitrary EMACS_INT values
8855 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8856 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8857 (tiff_load, imagemagick_load_image):
8858 Check for overflow in size calculations.
8859 (x_create_x_image_and_pixmap): Remove unnecessary test for
8860 xmalloc returning NULL; that can't happen.
8861 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8862 (xpm_color_bucket): Use better integer hashing function.
8863 (xpm_cache_color): Don't possibly over-allocate memory.
8864 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8865 (gif_memory_source):
8866 Use ptrdiff_t, not int or size_t, to record sizes.
8867 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8868 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8869 either works, as we prefer signed integers.
8870 (tiff_read_from_memory, tiff_write_from_memory):
8871 Return tsize_t, not size_t, since that's what the TIFF API wants.
8872 (tiff_read_from_memory): Don't fail simply because the read would
8873 go past EOF; instead, return a short read.
8874 (tiff_load): Omit no-longer-needed casts.
8875 (Fimagemagick_types): Don't assume size fits into 'int'.
8877 Improve hashing quality when configured --with-wide-int.
8878 * fns.c (hash_string): New function, taken from sxhash_string.
8879 Do not discard information about ASCII character case; this
8880 discarding is no longer needed.
8881 (sxhash-string): Use it. Change sig to match it. Caller changed.
8882 * lisp.h: Declare it.
8883 * lread.c (hash_string): Remove, since we now use fns.c's version.
8884 The fns.c version returns a wider integer if --with-wide-int is
8885 specified, so this should help the quality of the hashing a bit.
8887 * emacs.c: Integer overflow minor fix.
8888 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8889 Define only if GNU_LINUX.
8890 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8892 * dispnew.c: Integer signedness and overflow fixes.
8893 Remove unnecessary forward decls, that were a maintenance hassle.
8894 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8896 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8897 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8898 (prepare_desired_row, line_draw_cost):
8899 Use int, not unsigned, where either works.
8900 (save_current_matrix, restore_current_matrix):
8901 Use ptrdiff_t, not size_t, where either works.
8902 (init_display): Check for overflow more accurately, and without
8903 relying on undefined behavior.
8905 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8906 Remove, replacing with the new symbols in lisp.h. All uses changed.
8907 * fileio.c (make_temp_name):
8908 * filelock.c (lock_file_1, lock_file):
8909 * xdisp.c (message_dolog):
8910 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8911 Use pMd etc. instead.
8912 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8913 replacing the pWIDE etc. symbols removed from editfns.c.
8915 * keyboard.h (num_input_events): Now uintmax_t.
8916 This is (very slightly) less likely to mess up due to wraparound.
8919 * buffer.c: Integer signedness fixes.
8920 (alloc_buffer_text, enlarge_buffer_text):
8921 Use ptrdiff_t rather than size_t when either will do, as we prefer
8924 * alloc.c: Integer signedness and overflow fixes.
8925 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8926 (__malloc_size_t): Default to size_t, not to int.
8927 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8928 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8929 Prefer ptrdiff_t to size_t when either would do, as we prefer
8931 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8932 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8933 Now const. Initialize with values that are in range even if char
8935 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8936 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8937 These functions do the right thing with sizes > 2**32.
8938 (check_depth): Now ptrdiff_t, not int.
8939 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8940 Adjust to new way of storing sizes. Check for size overflow bugs
8942 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8943 slightly wrong anyway, as it missed one instance of
8944 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8945 (refill_memory_reserve): Omit needless cast to size_t.
8946 (mark_object_loop_halt): Mark as externally visible.
8948 * xselect.c: Integer signedness and overflow fixes.
8949 (Fx_register_dnd_atom, x_handle_dnd_message):
8950 Use ptrdiff_t, not size_t, since we prefer signed.
8951 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8952 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8953 x_dnd_atoms_size and x_dnd_atoms_length.
8955 * doprnt.c: Prefer signed to unsigned when either works.
8957 * doprnt.c (doprnt):
8959 * xdisp.c (vmessage):
8960 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8961 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8962 prefer signed arithmetic to avoid comparison confusion.
8963 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8964 but is a bit tricky.
8966 Assume freestanding C89 headers, string.h, stdlib.h.
8967 * data.c, doprnt.c, floatfns.c, print.c:
8968 Include float.h unconditionally.
8969 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8970 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8971 * regex.c: Likewise for stddef.h, string.h.
8972 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8973 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8974 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8975 (STDC_HEADERS): Remove obsolete defines.
8976 * sysdep.c: Include limits.h unconditionally.
8978 Assume support for memcmp, memcpy, memmove, memset.
8979 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8980 * regex.c (memcmp, memcpy):
8981 Remove; we assume C89 now.
8983 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8984 (__malloc_safe_bcopy): Remove; no longer needed.
8986 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8987 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8988 well either way, and we prefer signed to unsigned.
8990 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8992 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8993 closes the connection while we're reading (bug#9182).
8995 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8997 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8998 are specified (Bug#9168).
9000 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9002 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9003 Found by GCC static checking and --with-wide-int on a 32-bit host.
9005 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9007 * xdisp.c (compute_display_string_pos): Fix logic of caching
9008 previous display string position. Initialize cached_prev_pos to
9009 -1. Fixes slow-down at the beginning of a buffer.
9011 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9013 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9014 for attrs[LFACE_FONTSET_INDEX].
9016 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9018 * xml.c (parse_region): Remove unused local
9019 that was recently introduced.
9021 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9023 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9024 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9026 * xdisp.c (move_it_in_display_line_to): Record the best matching
9027 position for TO_CHARPOS while scanning the line, and restore it on
9028 exit if none of the characters scanned was an exact match.
9029 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9030 when exact match is impossible due to invisible text, and the
9031 lines are truncated.
9033 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9035 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9038 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9040 Fix a significant slow-down of cursor motion with C-n, C-p,
9041 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9042 auto-repeat under bidi redisplay in fontified buffers.
9043 * xdisp.c (compute_stop_pos_backwards): New function.
9044 (next_element_from_buffer): Call compute_stop_pos_backwards to
9045 find a suitable prev_stop when we find ourselves before
9047 (reseat): Don't look for prev_stop, as that could mean a very long
9049 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9050 <cached_disp_overlay_modiff>: Cache for last found display string
9052 (compute_display_string_pos): Return the cached position if asked
9053 about the same buffer in the same area of character positions, and
9054 the buffer wasn't changed since the time the display string
9055 position was cached.
9057 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9059 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9060 is an integer, which is important for empty lines. (Bug#9149)
9062 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9064 * frame.c (Fmodify_frame_parameters): In tty case, update the
9065 default face if necessary (Bug#4238).
9067 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9069 * editfns.c (Fstring_to_char): No need to explain what a character
9070 is in the docstring (Bug#6576).
9072 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9074 * xml.c (parse_region): Make sure we always return a tree.
9076 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9078 * xml.c (parse_region): If a document contains only comments,
9081 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9083 * xml.c (make_dom): Return comments, too.
9085 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9088 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9089 and the surrounding thread.
9090 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9091 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9092 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9094 * s/openbsd.h (BROKEN_SIGIO): Define.
9095 * unexelf.c (unexec) [__OpenBSD__]:
9096 Don't update the .mdebug section of the Alpha COFF symbol table.
9098 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9100 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9103 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9105 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9106 This fixes some race conditions on the permissions of any newly
9109 * alloc.c (valid_pointer_p): Use pipe, not open.
9110 This fixes some permissions issues when debugging.
9112 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9113 If fchown fails to set both uid and gid, try to set just gid,
9114 as that is sometimes allowed. Adjust the file's mode to eliminate
9115 setuid or setgid bits that are inappropriate if fchown fails.
9117 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>

9135 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9136 This works around a problem with the previous change to Fcopy_file.
9137 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9138 and without this change, GCC might complain about discarding
9139 fchown's return value.
9141 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9143 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

9168 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9169 quotes the next character, and doesn't affect other longer
9170 sequences (bug#8935).

9184 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9185 (elsz): Now a signed constant, not a size_t var. We prefer signed
9186 types to unsigned, to avoid integer comparison confusion. Without
9187 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9188 "cannot optimize loop, the loop counter may overflow", a symptom
9190 * indent.c (Fvertical_motion): Mark locals as initialized.
9191 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9193 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9195 * search.c (Fre_search_backward): Mention `case-fold-search' in
9196 all the re_search_* functions (bug#8138).

9237 the iterator is before prev_stop.
9238 (init_iterator): Initialize bidi_p from the default value of
9239 bidi-display-reordering, not from buffer-local value. Use the
9240 buffer-local value only if initializing for buffer iteration.

9756 Random fixes. E.g., (random) never returned negative values.
9757 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9758 subseconds part to the entropy, as that's a bit more random.
9759 Prefer signed to unsigned, since the signedness doesn't matter and
9760 in general we prefer signed. When given a limit, use a
9761 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9762 latter isn't right if USE_2_TAGS_FOR_INTS.
9763 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9764 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9777 This is more efficient than Ffile_directory_p and avoids a minor race.
9779 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9781 * buffer.c (Foverlay_put): Say what the return value is
9784 * fileio.c (barf_or_query_if_file_exists): Check first if the file

9788 error be more correct.
9790 * fns.c (Frequire): Remove the mention of the .gz files, since
9791 that's installation-specific, but keep the mention of

9909 * eval.c (struct backtrace): Simplify and port the data structure.
9910 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9911 signed bit field, as this assumption is not portable and it makes
9912 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9913 "char debug_on_exit : 1" as this is not portable either; instead,
9914 use the portable "unsigned int debug_on_exit : 1". Remove unused

10079 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
10081 Integer and buffer overflow fixes (Bug#8873).
10083 * print.c (printchar, strout): Check for string overflow.
10084 (PRINTPREPARE, printchar, strout):
10085 Don't set size unless allocation succeeds.
10087 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
10088 for sizes. Check for string overflow more accurately.
10089 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
10091 * macros.c: Integer and buffer overflow fixes.
10092 * keyboard.h (struct keyboard.kbd_macro_bufsize):
10093 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
10094 Use ptrdiff_t, not int, for sizes.
10095 Don't increment bufsize until after realloc succeeds.
10096 Check for size-calculation overflow.
10097 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
10099 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
10101 * lread.c: Integer overflow fixes.
10102 (read_integer): Radix is now EMACS_INT, not int,
10103 to improve quality of diagnostics for out-of-range radices.
10104 Calculate buffer size correctly for out-of-range radices.
10105 (read1): Check for integer overflow in radices, and in
10106 read-circle numbers.
10107 (read_escape): Avoid int overflow.
10108 (Fload, openp, read_buffer_size, read1)
10109 (substitute_object_recurse, read_vector, read_list, map_obarray):
10110 Use ptrdiff_t, not int, for sizes.
10111 (read1): Use EMACS_INT, not int, for sizes.
10112 Check for size overflow.
10114 * image.c (cache_image): Check for size arithmetic overflow.

10122 (read_list): Don't assume file position fits in int.
10123 (read_escape): Check for hex character overflow.
10125 2011-06-22 Leo Liu <sdl.web@gmail.com>
10127 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
10128 Move to minibuffer.el.
10130 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10132 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10133 The following patches are for when GLYPH_DEBUG && !XASSERT.
10134 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10135 * dispnew.c (flush_stdout):
10136 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10137 Mark as externally visible.
10138 * dispnew.c (check_window_matrix_pointers): Now static.
10139 * dispnew.c (window_to_frame_vpos):
10140 * xfns.c (unwind_create_frame):
10141 * xterm.c (x_check_font): Remove unused local.
10142 * scroll.c (CHECK_BOUNDS):
10143 * xfaces.c (cache_fache): Rename local to avoid shadowing.
10144 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
10145 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
10146 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
10147 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
10149 (debug_method_add): Use va_list and vsprintf rather than relying
10150 on undefined behavior with wrong number of arguments.
10151 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10152 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10153 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10154 since we're not interested in debugging glyphs with old libraries.
10155 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10156 GCC 4.6.0's static checking.
10158 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10160 Integer overflow and signedness fixes (Bug#8873).

10169 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
10170 (x_create_bitmap_from_xpm_data):
10171 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
10172 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
10174 * xfaces.c (load_pixmap):
10175 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
10176 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
10177 (.bitmaps_last, struct x_output.icon_bitmap):
10178 Use ptrdiff_t, not int, for bitmap indexes.
10179 (x_allocate_bitmap_record): Check for size overflow.
10180 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
10182 Use ptrdiff_t, not int, for overlay counts.
10183 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
10184 * editfns.c (overlays_around, get_pos_property):
10185 * textprop.c (get_char_property_and_overlay):
10186 * xdisp.c (next_overlay_change, note_mouse_highlight):
10187 * xfaces.c (face_at_buffer_position):
10188 * buffer.c (OVERLAY_COUNT_MAX): New macro.
10189 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
10190 (Fnext_overlay_change, Fprevious_overlay_change)
10191 (mouse_face_overlay_overlaps, Foverlays_in):
10192 Use ptrdiff_t, not int, for sizes.
10193 (overlays_at, overlays_in): Check for size-calculation overflow.
10195 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10197 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10198 (x_session_initialize): Do not assume string length fits in int.
10200 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10201 This is unlikely, but can occur if DPI is outlandish.
10203 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10204 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10206 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10207 * xrdb.c (magic_file_p, search_magic_path):
10208 Omit last arg SUFFIX; it was always 0. All callers changed.
10209 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10211 * xfont.c (xfont_match): Avoid need for strlen.
10213 * xfns.c: Don't assume strlen fits in int.
10214 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10216 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10217 not unsigned long, as we prefer signed integers. All callers changed.
10218 Detect integer overflow in repeat count.
10219 (message_dolog): Don't assume print length fits in 39 bytes.
10220 (display_mode_element): Don't assume strlen fits in int.
10222 * termcap.c: Don't assume sizes fit in int and never overflow.
10223 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10224 (gobble_line): Check for size-calculation overflow.
10226 * minibuf.c (Fread_buffer):
10227 * lread.c (intern, intern_c_string):
10228 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10229 Don't assume string length fits in int.
10231 * keyboard.c (parse_tool_bar_item):
10232 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10234 * font.c: Don't assume string length fits in int.
10235 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10236 Use ptrdiff_t, not int.
10237 (font_intern_prop): Don't assume string length fits in int.
10238 Don't assume integer property fits in fixnum.
10239 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10241 * filelock.c: Fix some buffer overrun and integer overflow issues.
10242 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10243 Reformulate so as not to need the command string.
10244 Invoke gzip -cd rather than gunzip, as it's more portable.
10245 (lock_info_type, lock_file_1, lock_file):
10246 Don't assume pid_t and time_t fit in unsigned long.
10247 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10248 (current_lock_owner): Prefer signed type for sizes.
10249 Use memcpy, not strncpy, where memcpy is what is really wanted.
10250 Don't assume (via atoi) that time_t and pid_t fit in int.
10251 Check for time_t and/or pid_t out of range, e.g., via a network share.
10252 Don't alloca where an auto var works fine.
10254 * fileio.c: Fix some integer overflow issues.
10255 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10256 Don't assume string length fits in int.
10257 (directory_file_name): Don't assume string length fits in long.
10258 (make_temp_name): Don't assume pid fits in int, or that its print
10259 length is less than 20.
10261 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10263 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10265 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10267 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10268 We prefer signed integers, even for size calculations.
10270 * emacs.c: Don't assume string length fits in 'int'.
10271 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10272 (main): Don't invoke strlen when not needed.
10274 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10275 (XD_DEBUG_MESSAGE): Don't waste a byte.
10277 * callproc.c (getenv_internal_1, getenv_internal)
10278 (Fgetenv_internal):
10279 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10281 * lread.c (invalid_syntax): Omit length argument.
10282 All uses changed. This doesn't fix a bug, but it simplifies the
10283 code away from its former Hollerith-constant appearance, and it's
10284 one less 'int' to worry about when looking at integer-overflow issues.
10285 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10287 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10288 This didn't break anything, but it didn't help either.
10289 It's confusing to put a bogus integer in a place where the actual
10290 value does not matter.
10291 (LIST_END_P): Remove unused macro and its bogus comment.
10292 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10294 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10295 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10297 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10298 We prefer signed types, and the value cannot exceed the EMACS_INT
10299 range anyway (because otherwise the length would not be representable).
10300 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10301 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10302 This avoids a GCC warning when WIDE_EMACS_INT.
10304 * indent.c (sane_tab_width): New function.
10305 (current_column, scan_for_column, Findent_to, position_indentation)
10306 (compute_motion): Use it. This is just for clarity.
10307 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10309 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10311 * lisp.h (lint_assume): New macro.
10312 * composite.c (composition_gstring_put_cache):
10313 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10315 * editfns.c, insdel.c:
10316 Omit unnecessary forward decls, to simplify future changes.
10318 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10320 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10322 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10323 Use much-faster test for byte-length change.
10324 Don't assume string byte-length fits in 'int'.
10325 Check that character arg fits in 'int'.
10326 (mapcar1): Declare byte as byte, for clarity.
10328 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10330 * fns.c (concat): Catch string overflow earlier.
10331 Do not rely on integer wraparound.
10333 * dispextern.h (struct it.overlay_strings_charpos)
10334 (struct it.selective): Now EMACS_INT, not int.
10335 * xdisp.c (forward_to_next_line_start)
10336 (back_to_previous_visible_line_start)
10337 (reseat_at_next_visible_line_start, next_element_from_buffer):
10338 Don't arbitrarily truncate the value of 'selective' to int.
10340 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10342 * composite.c: Don't truncate sizes to 'int'.
10343 (composition_gstring_p, composition_reseat_it)
10344 (composition_adjust_point): Use EMACS_INT, not int.
10345 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10346 not EMACS_UINT, for indexes.
10348 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10350 * buffer.c: Include <verify.h>.
10351 (struct sortvec.priority, struct sortstr.priority):
10352 Now EMACS_INT, not int.
10353 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10354 (struct sortstr.size, record_overlay_string)
10355 (struct sortstrlist.size, struct sortlist.used):
10356 Don't truncate size to int.
10357 (record_overlay_string): Check for size-calculation overflow.
10358 (init_buffer_once): Check at compile-time, not run-time.
10360 2011-06-22 Jim Meyering <meyering@redhat.com>
10362 Don't leak an XBM-image-sized buffer
10363 * image.c (xbm_load): Free the image buffer after using it.
10365 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10368 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10369 that Sun C diagnosed.
10370 * fns.c (secure_hash): Fix pointer signedness issue.
10371 * intervals.c (static_offset_intervals): New function.
10372 (offset_intervals): Use it.
10374 2011-06-21 Leo Liu <sdl.web@gmail.com>
10377 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10380 * fns.c (secure_hash): Rename from crypto_hash_function and change
10381 the first arg to accept symbols.
10382 (Fsecure_hash): New primitive.
10383 (syms_of_fns): New symbols.
10385 2011-06-20 Deniz Dogan <deniz@dogan.se>
10387 * process.c (Fset_process_buffer): Clarify return value in
10390 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10392 * dispnew.c (add_window_display_history): Use BVAR.
10394 * xdisp.c (debug_method_add): Use BVAR.
10395 (check_window_end, dump_glyph_matrix, dump_glyph)
10396 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10398 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10401 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10402 check till after the cache is created in init_frame_faces.
10404 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10406 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10408 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10410 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10411 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10412 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10414 Improve buffer-overflow checking (Bug#8873).
10415 * fileio.c (Finsert_file_contents):
10416 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10417 Remove the old (too-loose) buffer overflow checks.
10418 They weren't needed, since make_gap checks for buffer overflow.
10419 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10420 The old code merely checked for Emacs fixnum overflow, and relied
10421 on undefined (wraparound) behavior. The new code avoids undefined
10422 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10424 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10425 Tune. Don't use wider integers than needed. Don't use alloca.
10426 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10428 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10430 * insdel.c, lisp.h (buffer_overflow): New function.
10431 (insert_from_buffer_1, replace_range, replace_range_2):
10432 * insdel.c (make_gap_larger):
10433 * editfns.c (Finsert_char):
10434 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10436 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10438 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10440 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10442 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10443 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10445 * fileio.c: Don't assume EMACS_INT fits in off_t.
10446 (emacs_lseek): New static function.
10447 (Finsert_file_contents, Fwrite_region): Use it.
10448 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10450 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10452 * fns.c: Don't overflow int when computing a list length.
10453 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10454 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10455 truncation on 64-bit hosts. Check for QUIT every
10456 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10457 faster and is responsive enough.
10458 (Flength): Report an error instead of overflowing an integer.
10459 (Fsafe_length): Return a float if the value is not representable
10460 as a fixnum. This shouldn't happen except in contrived situations.
10461 (Fnthcdr, Fsort): Don't assume list length fits in int.
10462 (Fcopy_sequence): Don't assume vector length fits in int.
10464 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10465 (header_size, word_size): New constants.
10466 (allocate_vectorlike): Don't check size overflow here.
10467 (allocate_vector): Check it here instead, since this is the only
10468 caller of allocate_vectorlike that could cause overflow.
10469 Check that the new vector's length is representable as a fixnum.
10471 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10472 The previous code was bogus. For example, next_almost_prime (32)
10473 returned 39, which is undesirable as it is a multiple of 3; and
10474 next_almost_prime (24) returned 25, which is a multiple of 5 so
10475 why was the code bothering to check for multiples of 7?
10477 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10479 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10481 Variadic C functions now count arguments with ptrdiff_t.
10482 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10483 Back then I didn't know that the Emacs coding style prefers signed int.
10484 Also, in the meantime I found a few more instances where arguments
10485 were being counted with int, which may truncate counts on 64-bit
10486 machines, or EMACS_INT, which may be unnecessarily wide.
10487 * lisp.h (struct Lisp_Subr.function.aMANY)
10488 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10489 Arg counts are now ptrdiff_t, not size_t.
10490 All variadic functions and their callers changed accordingly.
10491 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10492 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10493 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10494 * callint.c (Fcall_interactively): Check arg count for overflow,
10495 to avoid potential buffer overrun. Use signed char, not 'int',
10496 for 'varies' array, so that we needn't bother to check its size
10497 calculation for overflow.
10498 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10499 * eval.c (apply_lambda):
10500 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10501 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10502 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10504 * callint.c (Fcall_interactively): Don't use index var as event count.
10506 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10507 * mem-limits.h (SIZE): Remove; no longer used.
10509 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10511 Remove unnecessary casts.
10512 * xterm.c (x_term_init):
10513 * xfns.c (x_set_border_pixel):
10514 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10515 These aren't needed now that we assume ANSI C.
10517 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10518 It's more likely to cause problems (due to unsigned overflow)
10521 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10523 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10525 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10527 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10529 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10531 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10533 GLYPH_CODE_FACE returns EMACS_INT, not int.
10534 * dispextern.h (merge_faces):
10535 * xfaces.c (merge_faces):
10536 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10537 Don't assume EMACS_INT fits in int.
10539 * character.h (CHAR_VALID_P): Remove unused parameter.
10540 * fontset.c, lisp.h, xdisp.c: All uses changed.
10542 * editfns.c (Ftranslate_region_internal): Omit redundant test.
10544 * fns.c (concat): Minor tuning based on overflow analysis.
10545 This doesn't fix any bugs. Use int to hold character, instead
10546 of constantly refetching from Emacs object. Use XFASTINT, not
10547 XINT, for value known to be a character. Don't bother comparing
10548 a single byte to 0400, as it's always less.
10550 * floatfns.c (Fexpt):
10551 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
10553 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
10556 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
10558 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
10559 Without this fix, on a 64-bit host (aset S 0 4294967386) would
10560 incorrectly succeed when S was a string, because 4294967386 was
10561 truncated before it was used.
10563 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
10564 Otherwise, an out-of-range integer could cause undefined behavior
10567 * composite.c: Use int, not EMACS_INT, for characters.
10568 (fill_gstring_body, composition_compute_stop_pos): Use int, not
10569 EMACS_INT, for values that are known to be in character range.
10570 This doesn't fix any bugs but is the usual style inside Emacs and
10571 may generate better code on 32-bit machines.
10573 Make sure a 64-bit char is never passed to ENCODE_CHAR.
10574 This is for reasons similar to the recent CHAR_STRING fix.
10575 * charset.c (Fencode_char): Check that character arg is actually
10576 a character. Pass an int to ENCODE_CHAR.
10577 * charset.h (ENCODE_CHAR): Verify that the character argument is no
10578 wider than 'int', as a compile-time check to prevent future regressions
10581 * character.c (char_string): Remove unnecessary casts.
10583 Make sure a 64-bit char is never passed to CHAR_STRING.
10584 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
10585 by silently ignoring the top 32 bits, allowing some values
10586 that were far too large to be valid characters.
10587 * character.h: Include <verify.h>.
10588 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
10589 arguments are no wider than unsigned, as a compile-time check
10590 to prevent future regressions in this area.
10592 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10593 (Fsubst_char_in_region):
10595 * xdisp.c (decode_mode_spec_coding):
10596 Adjust to CHAR_STRING's new requirement.
10597 * editfns.c (Finsert_char, Fsubst_char_in_region):
10598 * fns.c (concat): Check that character args are actually
10599 characters. Without this test, these functions did the wrong
10600 thing with wildly out-of-range values on 64-bit hosts.
10602 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10603 These casts should not be needed on 32-bit hosts, either.
10604 * keyboard.c (read_char):
10605 * lread.c (Fload): Remove casts to unsigned.
10607 * lisp.h (UNSIGNED_CMP): New macro.
10608 This fixes comparison bugs on 64-bit hosts.
10609 (ASCII_CHAR_P): Use it.
10610 * casefiddle.c (casify_object):
10611 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10612 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10613 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10614 * dispextern.h (FACE_FROM_ID):
10615 * keyboard.c (read_char): Use UNSIGNED_CMP.
10617 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10618 not to EMACS_INT, to avoid GCC warning.
10620 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10622 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10623 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10624 isn't needed on 32-bit machines.
10626 * buffer.c (Fgenerate_new_buffer_name):
10627 Use EMACS_INT for count, not int.
10628 (advance_to_char_boundary): Return EMACS_INT, not int.
10630 * data.c (Qcompiled_function): Now static.
10632 * window.c (window_body_lines): Now static.
10634 * image.c (gif_load): Rename local to avoid shadowing.
10636 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10637 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10638 * alloc.c (make_save_value): Integer argument is now of type
10639 ptrdiff_t, not int.
10640 (mark_object): Use ptrdiff_t, not int.
10641 * lisp.h (pD): New macro.
10642 * print.c (print_object): Use it.
10644 * alloc.c: Use EMACS_INT, not int, to count objects.
10645 (total_conses, total_markers, total_symbols, total_vector_size)
10646 (total_free_conses, total_free_markers, total_free_symbols)
10647 (total_free_floats, total_floats, total_free_intervals)
10648 (total_intervals, total_strings, total_free_strings):
10649 Now EMACS_INT, not int. All uses changed.
10650 (Fgarbage_collect): Compute overall total using a double, so that
10651 integer overflow is less likely to be a problem. Check for overflow
10652 when converting back to an integer.
10653 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10654 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10655 These were 'int' variables that could overflow on 64-bit hosts;
10656 they were never used, so remove them instead of repairing them.
10657 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10658 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10659 Previously, this ceilinged at INT_MAX, but that doesn't work on
10661 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10663 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10664 (allocate_vectorlike): Check for ptrdiff_t overflow.
10665 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10666 when a (possibly-narrower) signed value would do just as well.
10667 We prefer using signed arithmetic, to avoid comparison confusion.
10669 * alloc.c: Catch some string size overflows that we were missing.
10670 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10671 for convenience in STRING_BYTES_MAX.
10672 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10673 The definition here is exact; the one in lisp.h was approximate.
10674 (allocate_string_data): Check for string overflow. This catches
10675 some instances we weren't catching before. Also, it catches
10676 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10677 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10678 and ptrdiff_t and EMACS_INT are both 64 bits.
10680 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10681 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10682 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10684 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10686 * alloc.c (Fmake_string): Check for out-of-range init.
10688 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10690 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10692 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10694 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10695 xg_get_default_scrollbar_width.
10697 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10698 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10699 (style_changed_cb): Call update_theme_scrollbar_width and call
10700 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10701 all frames (Bug#8505).
10702 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10703 Call gtk_window_set_resizable if HAVE_GTK3.
10704 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10705 and height if HAVE_GTK3 (Bug#8505).
10706 (scroll_bar_width_for_theme): New variable.
10707 (update_theme_scrollbar_width): New function.
10708 (xg_get_default_scrollbar_width): Move code to
10709 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10710 (xg_initialize): Call update_theme_scrollbar_width.
10712 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10714 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10716 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10718 * frame.c (make_frame): Call other_buffer_safely instead of
10721 * window.c (temp_output_buffer_show): Call display_buffer with
10722 second argument Vtemp_buffer_show_specifiers and reset latter
10723 immediately after the call.
10724 (Vtemp_buffer_show_specifiers): New variable.
10725 (auto_window_vscroll_p, next_screen_context_lines)
10726 (Vscroll_preserve_screen_position): Remove leading asterisks from
10729 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10731 Fix minor problems found by GCC 4.6.0 static checking.
10732 * buffer.c (Qclone_number): Remove for now, as it's unused.
10733 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10734 (record_buffer): Remove unused local.
10735 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10736 (set_frame_buffer_list): Remove; unused.

10740 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10742 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10743 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10744 Define only if HAVE_GPM.
10745 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10746 (update_hints_inhibit): Remove; never set. All uses removed.
10747 * widgetprv.h (emacsFrameClassRec): Remove decl.
10748 * window.c (delete_deletable_window): Now returns void, since it
10749 wasn't returning anything.
10750 (compare_window_configurations): Remove unused locals.
10751 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10752 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10753 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10754 the same widths as pointers. This follows up on the 2011-05-06 patch.
10755 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10756 * xterm.h: Likewise.

10764 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10766 * image.c (gif_load): Add animation frame delay to the metadata.
10767 (syms_of_image): Use DEFSYM. New symbol `delay'.
10769 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10771 * window.c (delete_deletable_window): Re-add.
10772 (Fset_window_configuration): Rewrite to handle dead buffers and
10773 consequently deletable windows.
10774 (window_tree, Fwindow_tree): Remove. Supply functionality in
10776 (compare_window_configurations): Simplify code.
10778 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10780 * image.c (imagemagick_load_image): Fix type mismatch.
10781 (Fimagemagick_types): Likewise.
10783 * window.h (replace_buffer_in_windows): Declare.
10785 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10787 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10788 Qclone_number. Remove external declaration of Qdelete_window.
10789 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10791 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10792 Run Qbuffer_list_update_hook if allowed.
10793 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10794 buffer list implementation.
10795 (other_buffer_safely): New function.
10796 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10797 calls to replace_buffer_in_windows and
10798 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10800 (record_buffer): Inhibit quitting and rewrite using quittable
10801 functions. Run Qbuffer_list_update_hook if allowed.
10802 (Frecord_buffer, Funrecord_buffer): New functions.
10803 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10804 Move switch-to-buffer to window.el.
10805 (bury-buffer): Move to window.el.
10806 (Vbuffer_list_update_hook): New variable.
10808 * lisp.h (other_buffer_safely): Add prototype in buffer.c

10813 (replace_buffer_in_all_windows): Remove prototype.
10814 (replace_buffer_in_windows_safely): Add prototype.
10816 * window.c: Declare Qdelete_window static again. Move down
10817 declaration of select_count.
10818 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10819 (Fother_window): Move to window.el.
10820 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10821 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.

10825 Qreplace_buffer_in_windows.
10826 (replace_buffer_in_all_windows): Remove with some functionality
10827 moved into replace_buffer_in_windows_safely.
10828 (replace_buffer_in_windows_safely): New function.
10829 (select_window_norecord, select_frame_norecord): Move in front
10830 of run_window_configuration_change_hook. Remove now obsolete

10834 (keys_of_window): Move binding for other-window to window.el.
10836 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10838 * dispextern.h (struct image): Replace data member, whose int_val
10839 and ptr_val fields were not used by anything, with a single
10842 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
10843 (gif_clear_image, gif_load, imagemagick_load_image)

10902 match the prototype.
10904 2011-06-10 Martin Rudalics <rudalics@gmx.at>
10906 * window.c: Remove declarations of Qwindow_size_fixed,
10907 window_min_size_1, window_min_size_2, window_min_size,
10908 size_window, window_fixed_size_p, enlarge_window, delete_window.
10909 Remove static from declaration of Qdelete_window, it's

11289 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11290 value of a `display' property is a "replacing spec".
11291 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11292 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

11322 * gnutls.c: Use Emacs's memory allocators.
11323 Without this change, the gnutls library would invoke malloc etc.
11324 directly, which causes problems on non-SYNC_INPUT hosts, and which
11325 runs afoul of improving memory_full behavior. (Bug#8761)
11326 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11327 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11328 xfree instead of the default malloc, realloc, free.
11329 (Fgnutls_boot): No need to check for memory allocation failure,
11330 since xmalloc does that for us.

11350 * lisp.h (struct Lisp_Hash_Table):
11351 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11352 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11353 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11354 * alloc.c (allocate_vectorlike):
11355 Check for overflow in vector size calculations.
11356 * ccl.c (ccl_driver):
11357 Check for overflow when converting EMACS_INT to int.
11358 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11359 need to be updated by these changes.
11360 * fns.c (make_hash_table, maybe_resize_hash_table):
11361 Check for integer overflow with large hash tables.
11362 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11363 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11364 (SXHASH_REDUCE): New macro.
11365 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11366 Use it instead of discarding useful hash info with large hash values.
11367 (sxhash_float): New function.
11368 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11369 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11370 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11371 Rewrite to use FIXNUM_BITS, as this simplifies things.
11372 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11373 Adjust signatures to match updated version of code.
11374 (consing_since_gc): Now EMACS_INT, since a single hash table can
11375 use more than INT_MAX bytes.
11377 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
11379 Make it possible to build with GCC-4.6+ -O2 -flto.

11388 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
11390 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
11391 Update dependencies.
11393 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11395 * data.c (init_data): Remove code for UTS, this system is not
11398 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11400 Don't force ./temacs to start in terminal mode.
11402 * frame.c (make_initial_frame): Initialize faces in all cases, not
11403 only when CANNOT_DUMP is defined.
11404 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
11406 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11408 * dispnew.c (add_window_display_history): Use const for the string
11409 pointer. Remove declaration, not needed.
11411 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11413 Use 'inline', not 'INLINE'.
11414 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
11415 * alloc.c, fontset.c (INLINE): Remove.
11416 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
11417 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
11418 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
11419 * gmalloc.c (register_heapinfo): Use inline unconditionally.
11420 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
11422 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
11424 Make it possible to run ./temacs.
11426 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11427 syms_of_callproc does the same thing. Remove test for
11428 "initialized", do it in the caller.
11429 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11431 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
11433 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
11434 (read_minibuf): Use get_minibuffer.
11435 (syms_of_minibuf): Use DEFSYM.
11436 (Qmetadata): New var.
11437 * data.c (Qbuffer): Don't make it static.
11438 (syms_of_data): Use DEFSYM.
11440 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
11442 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
11443 (CCL_CODE_MIN): New macro.
11445 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
11447 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
11449 * eval.c (Qdebug): Now static.
11450 * lisp.h (Qdebug): Remove decl. This reverts a part of the
11451 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
11452 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
11454 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11456 * image.c: Various fixes to ImageMagick code comments.
11457 (Fimagemagick_types): Doc fix.
11459 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
11461 Minor fixes prompted by GCC 4.6.0 warnings.
11463 * xselect.c (converted_selections, conversion_fail_tag): Now static.
11465 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
11466 (x_clipboard_manager_save_all): Move extern decl to ...
11467 * xterm.h: ... here, so that it can be checked for consistency.
11469 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
11471 * xselect.c (x_clipboard_manager_save_frame)
11472 (x_clipboard_manager_save_all): New functions.
11473 (Fx_clipboard_manager_save): Lisp function deleted.
11475 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
11476 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
11478 * xterm.h: Update prototype.
11480 2011-05-28 William Xu <william.xwl@gmail.com>
11482 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
11483 exiting (Bug#8239).
11485 2011-05-28 Jim Meyering <meyering@redhat.com>
11487 Avoid a sign-extension bug in crypto_hash_function.
11488 * fns.c (to_uchar): Define.
11489 (crypto_hash_function): Use it to convert some newly-signed
11490 variables to unsigned, to avoid sign-extension bugs. For example,
11491 without this change, (md5 "truc") would evaluate to
11492 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11493 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11494 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11496 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11498 Integer overflow fixes.
11500 * dbusbind.c: Serial number integer overflow fixes.
11501 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11502 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11503 to hold a serial number that is too large for a fixnum.
11504 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11505 Check for serial numbers out of range. Decode any serial number
11506 that was so large that it became a float. (Bug#8722)
11508 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11509 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11510 Use XFASTINT rather than XUINT when numbers are nonnegative.
11511 (xd_append_arg, Fdbus_method_return_internal):
11512 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11513 arguments, check that Lisp number is nonnegative, rather than
11514 silently wrapping negative numbers around. (Bug#8722)
11515 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11518 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11520 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11522 ccl: Add integer overflow checks.
11523 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11524 (IN_INT_RANGE): New macros.
11525 (ccl_driver): Use them to check for integer overflow when
11526 decoding a CCL program. Many of the new checks are whether XINT (x)
11527 fits in int; it doesn't always, on 64-bit hosts. The new version
11528 doesn't catch all possible integer overflows, but it's an
11529 improvement. (Bug#8719)
11531 * alloc.c (make_event_array): Use XINT, not XUINT.
11532 There's no need for unsigned here.
11534 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11535 This follows up to the 2011-05-06 change that substituted uintptr_t
11536 for EMACS_INT. This case wasn't caught back then.
11538 Rework Fformat to avoid integer overflow issues.
11539 * editfns.c: Include <float.h> unconditionally, as it's everywhere
11540 now (part of C89). Include <verify.h>.
11541 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
11542 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
11543 (Fformat): Avoid the prepass trying to compute sizes; it was only
11544 approximate and thus did not catch overflow reliably. Instead, walk
11545 through the format just once, formatting and computing sizes as we go,
11546 checking for integer overflow at every step, and allocating a larger
11547 buffer as needed. Keep track separately whether the format is
11548 multibyte. Keep only the most-recently calculated precision, rather
11549 than them all. Record whether each argument has been converted to
11550 string. Use EMACS_INT, not int, for byte and char and arg counts.
11551 Support field widths and precisions larger than INT_MAX. Avoid
11552 sprintf's undefined behavior with conversion specifications such as %#d
11553 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
11554 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
11555 formatting out-of-range floating point numbers with int
11556 formats. (Bug#8668)
11558 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
11560 * data.c: Avoid integer truncation in expressions involving floats.
11561 * data.c: Include <intprops.h>.
11562 (arith_driver): When there's an integer overflow in an expression
11563 involving floating point, convert the integers to floating point
11564 so that the resulting value does not suffer from catastrophic
11565 integer truncation. For example, on a 64-bit host (* 4
11566 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
11567 Do not rely on undefined behavior after integer overflow.
11569 merge count_size_as_multibyte, parse_str_to_multibyte
11570 * character.c, character.h (count_size_as_multibyte):
11571 Rename from parse_str_to_multibyte; all uses changed.
11572 Check for integer overflow.
11573 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
11574 since it's now a duplicate of the other. This is more of
11575 a character than a buffer op, so better that it's in character.c.
11576 * fns.c, print.c: Adjust to above changes.
11578 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
11580 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
11582 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11584 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11585 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
11586 (x_clipboard_manager_save): Now static.
11587 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
11589 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
11590 (crypto_hash_function): Now static.
11591 Fix pointer signedness problems. Avoid unnecessary initializations.
11593 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11595 * termhooks.h (Vselection_alist): Make it terminal-local.
11597 * terminal.c (create_terminal): Initialize it.
11599 * xselect.c: Support for clipboard managers.
11600 (Vselection_alist): Move to termhooks.h as terminal-local var.
11601 (LOCAL_SELECTION): New macro.
11602 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11603 (symbol_to_x_atom): Remove gratuitous arg.
11604 (x_handle_selection_request, lisp_data_to_selection_data)
11605 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11606 (x_own_selection, x_get_local_selection, x_convert_selection):
11607 New arg, specifying work frame. Use terminal-local Vselection_alist.
11608 (some_frame_on_display): Delete unused function.
11609 (Fx_own_selection_internal, Fx_get_selection_internal)
11610 (Fx_disown_selection_internal, Fx_selection_owner_p)
11611 (Fx_selection_exists_p): New optional frame arg.
11612 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11613 (x_handle_selection_clear): Don't treat other terminals with the
11614 same keyboard specially. Use the terminal-local Vselection_alist.
11615 (x_clear_frame_selections): Use Frun_hook_with_args.
11617 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11619 * xterm.h: Add support for those atoms.
11621 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11623 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11624 (converted_selections, conversion_fail_tag): New global variables.
11625 (x_selection_request_lisp_error): Free the above.
11626 (x_get_local_selection): Remove unnecessary code.
11627 (x_reply_selection_request): Args changed; handle arbitrary array
11628 of converted selections stored in converted_selections.
11629 Separate the XChangeProperty and SelectionNotify steps.
11630 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11631 (x_convert_selection): New function.
11632 (x_handle_selection_event): Simplify.
11633 (x_get_foreign_selection): Don't ignore incoming requests while
11634 waiting for an answer; this will fail when we implement
11635 SAVE_TARGETS, and seems unnecessary anyway.
11636 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11637 (Vx_sent_selection_functions): Doc fix.
11639 2011-05-26 Leo Liu <sdl.web@gmail.com>
11641 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11643 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11645 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11647 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11648 for fringe update if it has periodic bitmap.
11649 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11650 and fringe_bitmap_periodic_p.
11652 * fringe.c (get_fringe_bitmap_data): New function.
11653 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11654 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11655 row. Mark glyph row for fringe update if periodicity changed.
11657 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11658 for fringe update unless it has periodic bitmap.
11660 2011-05-25 Kenichi Handa <handa@m17n.org>
11662 * xdisp.c (get_next_display_element): Set correct it->face_id for
11663 a static composition.
11665 2011-05-24 Leo Liu <sdl.web@gmail.com>
11668 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11670 * fns.c (crypto_hash_function, Fsha1): New function.
11671 (Fmd5): Use crypto_hash_function.
11672 (syms_of_fns): Add Ssha1.
11674 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11676 * gnutls.c: Remove unused macros.
11677 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11678 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11679 Remove macros that are defined and never used.
11680 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11682 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11684 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11685 (Fx_get_selection_internal): Minor cleanup.
11686 (Fx_own_selection_internal): Rename arguments for consistency with
11689 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11691 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.

11704 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11705 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11706 and add some more files.

11710 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11711 report_file_error introduced by the change from 2011-05-07.
11713 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11715 * systime.h (Time): Define only if emacs is defined.
11716 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11717 where the include path doesn't have X11/X.h by default. See
11718 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11720 2011-05-20 Kenichi Handa <handa@m17n.org>
11722 * composite.c (find_automatic_composition): Fix previous change.
11724 2011-05-20 Glenn Morris <rgm@gnu.org>
11726 * lisp.mk: New file, split from Makefile.in.
11727 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11728 (shortlisp): Remove.
11729 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11731 2011-05-19 Glenn Morris <rgm@gnu.org>
11733 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11734 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11735 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11736 (lisp): Set the order to that of loadup.el.
11737 (shortlisp): Make it a copy of $lisp.
11738 (SOME_MACHINE_LISP): Remove.
11739 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11740 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11742 2011-05-18 Kenichi Handa <handa@m17n.org>
11744 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11745 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11746 (find_automatic_composition): Mostly rewrite for efficiency.
11748 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11750 * makefile.w32-in: Update dependencies.
11752 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11754 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11755 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11757 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11759 Fix some integer overflow issues, such as string length overflow.
11761 * insdel.c (count_size_as_multibyte): Check for string overflow.
11763 * character.c (lisp_string_width): Check for string overflow.
11764 Use EMACS_INT, not int, for string indexes and lengths; in
11765 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11766 the resulting string length overflows an EMACS_INT; instead,
11767 report a string overflow if no precision given. When checking for
11768 precision exhaustion, use a check that cannot possibly have
11769 integer overflow. (Bug#8675)
11770 * character.h (lisp_string_width): Adjust to new signature.
11772 * alloc.c (string_overflow): New function.
11773 (Fmake_string): Use it. This doesn't change behavior, but saves
11774 a few bytes and will simplify future changes.
11775 * character.c (string_escape_byte8): Likewise.
11776 * lisp.h (string_overflow): New decl.
11778 Fixups, following up to the user-interface timestamp change.
11779 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11780 for UI timestamps, instead of unsigned long.
11781 * msdos.c (mouse_get_pos): Likewise.
11782 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11783 * w32gui.h (Time): Define by including "systime.h" rather than by
11784 declaring it ourselves. (Bug#8664)
11786 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11787 * image.c (clear_image_cache): Likewise.
11789 * term.c (term_mouse_position): Don't assume time_t wraparound.
11791 Be more systematic about user-interface timestamps.
11792 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11793 and sometimes 'EMACS_UINT', to represent these timestamps.
11794 This change causes it to use 'Time' uniformly, as that's what X uses.
11795 This makes the code easier to follow, and makes it easier to catch
11796 integer overflow bugs such as Bug#8664.
11797 * frame.c (Fmouse_position, Fmouse_pixel_position):
11798 Use Time, not unsigned long, for user-interface timestamps.
11799 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11800 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11801 * keyboard.h (last_event_timestamp): Likewise.
11802 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11803 * menu.h (xmenu_show): Likewise.
11804 * term.c (term_mouse_position): Likewise.
11805 * termhooks.h (struct input_event.timestamp): Likewise.
11806 (struct terminal.mouse_position_hook): Likewise.
11807 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11808 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11809 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11810 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11811 what it was before.
11812 * menu.h, termhooks.h: Include "systime.h", for Time.
11814 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11815 Don't assume that the difference between two unsigned long values
11816 can fit into an integer. At this point, we know button_down_time
11817 <= event->timestamp, so the difference must be nonnegative, so
11818 there's no need to cast the result if double-click-time is
11819 nonnegative, as it should be; check that it's nonnegative, just in
11820 case. This bug is triggered when events are more than 2**31 ms
11821 apart (about 25 days). (Bug#8664)
11823 * xselect.c (last_event_timestamp): Remove duplicate decl.
11824 (x_own_selection): Remove needless cast to unsigned long.
11826 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11827 that always fit in int. Use a sentinel instead of a counter, to
11828 avoid a temp and to allay GCC's concerns about possible int overflow.
11829 * frame.h (struct frame): Use int for menu_bar_items_used
11830 instead of EMACS_INT, since it always fits in int.
11832 * menu.c (grow_menu_items): Check for int overflow.
11834 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11836 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11837 Before, the code was not consistent. These values cannot exceed
11838 2**31 - 1 so there's no need to make them unsigned.
11839 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11840 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11841 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11843 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11845 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11846 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11847 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11848 presumably because the widths might not match.
11850 * window.c (size_window): Avoid needless test at loop start.
11852 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11854 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11856 2011-05-12 Drew Adams <drew.adams@oracle.com>
11858 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11860 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11862 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11863 `width' to `bar_area_x' and `bar_area_width', respectively.
11864 (x_scroll_run): Take account of fringe background extension.
11866 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11867 Rename local vars `left' and `width' to `bar_area_x' and
11868 `bar_area_width', respectively.
11869 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11870 background extension.
11872 2011-05-10 Jim Meyering <meyering@redhat.com>
11874 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11876 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11878 * image.c (Finit_image_library): Return t for built-in image types,
11879 like pbm and xbm. (Bug#8640)
11881 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11883 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11885 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11887 * w32console.c (Fset_screen_color): Doc fix.
11888 (Fget_screen_color): New function.
11889 (syms_of_ntterm): Defsubr it.
11891 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11892 unlink the temporary file if Fcall_process didn't create it in the
11894 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11895 child process will be redirected to a file specified with `:file'.
11896 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11897 cue to call_process_cleanup not to close that handle.
11899 2011-05-07 Ben Key <bkey76@gmail.com>
11901 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11902 one of two shell specific rules, either bootstrap-temacs-CMD or
11903 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11904 to the previous implementation of the bootstrap-temacs rule.
11905 The bootstrap-temacs-CMD rule is similar to the previous
11906 implementation of the bootstrap-temacs rule except that it
11907 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11910 These changes, along with some changes to nt/configure.bat,
11911 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11912 earlier fix to add support for --cflags and --ldflags options
11913 that include quotes so that it works whether make uses cmd or
11916 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11918 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11919 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11921 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11922 a string. Handle both cases.
11923 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11924 (Fdbus_register_method): Use Qinvalid_function.
11926 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11928 * makefile.w32-in: Update dependencies.
11929 (LISP_H): Add inttypes.h and stdin.h.
11930 (PROCESS_H): Add unistd.h.
11932 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11934 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11935 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11937 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11939 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11941 * term.c (vfatal): Remove stray call to va_end.
11942 It's not needed and the C Standard doesn't allow it here anyway.
11944 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11945 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11947 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11950 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11952 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11954 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11956 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11958 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11960 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11961 * charset.c (Fdefine_charset_internal): Don't initialize
11962 charset.code_space[15]. The value was garbage, on hosts with
11963 32-bit int (Bug#8600).
11965 * lread.c (read_integer): Be more consistent with string-to-number.
11966 Use string_to_number to do the actual conversion; this avoids
11967 rounding errors and fixes some other screwups. Without this fix,
11968 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11969 (digit_to_number): Move earlier, for benefit of read_integer.
11970 Return -1 if the digit is out of range for the base, -2 if it is
11971 not a digit in any supported base. (Bug#8602)
11973 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11975 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11976 to match comment at start of function. This also removes a
11977 GCC warning about overflow in a 32+64-bit port.
11979 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11981 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11982 Reported by Stefan Monnier in
11983 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11984 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11985 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11987 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11988 (EMACS_UINTPTR): Likewise, with uintptr_t.
11990 * lisp.h: Prefer 64-bit EMACS_INT if available.
11991 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11992 on 32-bit hosts that have 64-bit int, so that they can access
11994 However, temporarily disable this change unless the temporary
11995 symbol WIDE_EMACS_INT is defined.
11997 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11999 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12000 This removes an assumption that EMACS_INT and long are the same
12001 width as pointers. The assumption is true for Emacs porting targets
12002 now, but we want to make other targets possible.
12003 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12004 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12005 In the rest of the code, change types of integers that hold casted
12006 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12007 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12008 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12009 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12010 No need to cast type when ORing.
12011 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12012 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12013 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12014 assume EMACS_INT is the same width as char *.
12015 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12016 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12017 Remove no-longer-needed casts.
12018 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12019 (xg_tool_bar_help_callback, xg_make_tool_item):
12020 Use EMACS_INTPTR to hold an integer
12021 that will be cast to void *; this can avoid a GCC warning
12022 if EMACS_INT is not the same width as void *.
12023 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12024 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12025 (current_message_1, set_message_1):
12026 Use a local to convert to proper width without a cast.
12027 * xmenu.c (dialog_selection_callback): Likewise.
12029 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12030 Also, don't assume VALBITS / RAND_BITS is less than 5,
12031 and don't rely on undefined behavior when shifting a 1 left into
12033 * lisp.h (get_random): Change signature to match.
12035 * lread.c (hash_string): Use size_t, not int, for hash computation.
12036 Normally we prefer signed values; but hashing is special, because
12037 it's better to use unsigned division on hash table sizes so that
12038 the remainder is nonnegative. Also, size_t is the natural width
12039 for hashing into memory. The previous code used 'int', which doesn't
12040 retain enough info to hash well into very large tables.
12041 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12043 * dbusbind.c: Don't possibly lose pointer info when converting.
12044 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12045 Use XPNTR rather than XHASH, so that the high-order bits of
12046 the pointer aren't lost when converting through void *.
12048 * eval.c (Fautoload): Don't double-shift a pointer.
12050 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12052 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12054 * gnutls.c (DEF_GNUTLS_FN):
12055 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12057 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12059 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12062 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12064 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12065 New version that can reserve upto 2GB of heap space.
12067 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12069 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12071 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12073 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12074 `gnutls_certificate_set_x509_key_file'.
12076 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12078 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12079 Update dependencies.
12081 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12083 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12084 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12085 Remove unused parameter `fildes'.
12086 * process.c (read_process_output, send_process): Don't pass it.
12088 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12090 Fix previous change: the library cache is defined in w32.c.
12091 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12092 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12094 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12096 Implement dynamic loading of GnuTLS on Windows.
12098 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12099 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12100 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12103 * gnutls.c (Qgnutls_dll): Define.
12104 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12105 (gnutls_*): Declare function pointers.
12106 (init_gnutls_functions): New function to initialize function pointers.
12107 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12108 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12109 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12110 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12111 (emacs_gnutls_write, emacs_gnutls_read)
12112 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12113 (Fgnutls_available_p): New function.
12114 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12115 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
12116 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
12118 * image.c: Include w32.h.
12119 (Vimage_type_cache): Delete.
12120 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12121 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12122 (w32_delayed_load): Move to w32.c.
12124 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12126 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12127 (w32_delayed_load): Move from image.c. When loading a library, record
12128 its filename in the :loaded-from property of the library id.
12129 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12130 Initialize and staticpro them.
12131 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12133 * process.c: Include lisp.h before w32.h, not after.
12134 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12135 instead of gnutls_record_check_pending.
12137 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12139 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12141 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12142 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12145 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12147 * xterm.c (x_set_frame_alpha): Do not set property on anything
12148 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12150 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12152 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12154 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12156 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12157 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
12158 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

12163 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
12164 (Qgnutls_bootprop_callbacks_verify): Make static.
12166 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
12168 * callproc.c: Indentation fixup.
12170 * sysdep.c (wait_for_termination_1): Make static.
12171 (wait_for_termination, interruptible_wait_for_termination):
12172 Move after wait_for_termination_1.
12174 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12176 * sysdep.c (interruptible_wait_for_termination): New function
12177 which is like wait_for_termination, but allows keyboard
12180 * callproc.c (Fcall_process): Add (:file "file") as an option for
12182 (Fcall_process_region): Ditto.
12184 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12186 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12187 rather than `XVECTOR (FOO)->size'.
12189 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12190 inttypes.h, as a gnulib replacement is used if it not available in
12193 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12195 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12196 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12197 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12199 * coding.c (coding_alloc_by_realloc): Error out if destination
12200 will grow beyond MOST_POSITIVE_FIXNUM.
12201 (decode_coding_emacs_mule): Abort if there isn't enough place in
12202 charbuf for the composition carryover bytes. Reserve an extra
12203 space for up to 2 characters produced in a loop.
12204 (decode_coding_iso_2022): Abort if there isn't enough place in
12205 charbuf for the composition carryover bytes.
12207 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12209 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12210 aborting when %lld or %lll format is passed.
12211 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12212 %llo or %llx format is passed. (Bug#8545)
12214 * window.c (window_scroll_line_based): Use a marker instead of
12215 simple variables to record original value of point. (Bug#7952)
12217 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12218 produced by %s or %c overflows available buffer space. (Bug#8545)
12220 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12222 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12223 (SIZE_MAX): Move defn after all includes, as they might #define it.
12225 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12227 * w32.c (init_environment): Warn about defaulting HOME to C:\.
12229 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12231 * keyboard.c (Qdelayed_warnings_hook): Define.
12232 (command_loop_1): Run `delayed-warnings-hook'
12233 if Vdelayed_warnings_list is non-nil.
12234 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
12235 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12237 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12239 * doprnt.c (doprnt): Don't return value smaller than the buffer
12240 size if the message was truncated. (Bug#8545).
12242 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12244 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12245 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12247 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12249 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12251 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12253 * makefile.w32-in: Update dependencies.
12255 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12257 Improve `doprnt' and its usage. (Bug#8545)
12258 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12259 `format_end'. Remove support for %l as a conversion specifier.
12260 Don't use xrealloc. Improve diagnostics when the %l size modifier
12261 is used. Update the commentary.
12263 * eval.c (verror): Simplify calculation of size_t.
12265 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12268 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12270 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12273 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12275 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12276 This makes this file independent of the recent pseudovector change.
12278 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12280 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12282 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12283 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12284 Remove unused local.
12285 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12287 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12288 GCC 4.6.0 optimizes based on type-based alias analysis.
12289 For example, if b is of type struct buffer * and v of type struct
12290 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12291 != &v->size, and therefore "v->size = 1; b->size = 2; return
12292 v->size;" must therefore return 1. This assumption is incorrect
12293 for Emacs, since it type-puns struct Lisp_Vector * with many other
12294 types. To fix this problem, this patch adds a new type struct
12295 vectorlike_header that documents the constraints on layout of vectors
12296 and pseudovectors, and helps optimizing compilers not get fooled
12297 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12298 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12299 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12301 (XSETPVECTYPE): Rewrite in terms of new macro.
12302 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12303 This is a bit clearer, and further avoids the possibility of
12304 undesirable aliasing.
12305 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12306 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12307 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12308 since Lisp_Subr is a special case (no "next" field).
12309 (ASIZE): Now uses header.size rather than size.
12310 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12311 to avoid the hassle of writing XVECTOR (foo)->header.size.
12312 (struct vectorlike_header): New type.
12313 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12314 object, to help avoid aliasing.
12315 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12316 (SUBRP): Likewise, since Lisp_Subr is a special case.
12317 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12318 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12319 (struct Lisp_Hash_Table): Combine first two members into a single
12320 struct vectorlike_header member. All uses of "size" and "next" members
12321 changed to be "header.size" and "header.next".
12322 * buffer.h (struct buffer): Likewise.
12323 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12324 * frame.h (struct frame): Likewise.
12325 * process.h (struct Lisp_Process): Likewise.
12326 * termhooks.h (struct terminal): Likewise.
12327 * window.c (struct save_window_data, struct saved_window): Likewise.
12328 * window.h (struct window): Likewise.
12329 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12330 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12331 * buffer.c (init_buffer_once): Likewise.
12332 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12334 * process.c (Fformat_network_address): Use local var for size,
12337 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12339 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12340 * data.c (atof): Remove decl; no longer used or needed.
12341 (digit_to_number): Move to lread.c.
12342 (Fstring_to_number): Use new string_to_number function, to be
12343 consistent with how the Lisp reader treats infinities and NaNs.
12344 Do not assume that floating-point numbers represent EMACS_INT
12345 without losing information; this is not true on most 64-bit hosts.
12346 Avoid double-rounding errors, by insisting on integers when
12347 parsing non-base-10 numbers, as the documentation specifies.
12348 * lisp.h (string_to_number): New decl, replacing ...
12349 (isfloat_string): Remove.
12350 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12351 (read1): Do not accept +. and -. as integers; this
12352 appears to have been a coding error. Similarly, do not accept
12353 strings like +-1e0 as floating point numbers. Do not report
12354 overflow for integer overflows unless the base is not 10 which
12355 means we have no simple and reliable way to continue.
12356 Break out the floating-point parsing into a new
12357 function string_to_number, so that Fstring_to_number parses
12358 floating point numbers consistently with the Lisp reader.
12359 (digit_to_number): Move here from data.c. Make it static inline.
12360 (E_CHAR, EXP_INT): Remove, replacing with ...
12361 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12362 (string_to_number): New function, replacing isfloat_string.
12363 This function checks for valid syntax and produces the resulting
12364 Lisp float number too. Rework it so that string-to-number
12365 no longer mishandles examples like "1.0e+". Use strtoumax,
12366 so that overflow for non-base-10 numbers is reported only when
12367 there's no portable and simple way to convert to floating point.
12369 * textprop.c (set_text_properties_1): Rewrite for clarity,
12370 and to avoid GCC warning about integer overflow.
12372 * intervals.h (struct interval): Use EMACS_INT for members
12373 where EMACS_UINT might cause problems. See
12374 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12375 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12376 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12378 (offset_intervals): Tell GCC not to worry about length overflow
12379 when negating a negative length.
12381 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12382 (overrun_check_free): Likewise.
12384 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12385 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12388 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12389 (gnutls_make_error): Rename local to avoid shadowing.
12390 (gnutls_emacs_global_deinit): ifdef out; not used.
12391 (Fgnutls_boot): Use const for pointer to readonly storage.
12392 Comment out unused local. Fix pointer signedness problems.
12394 * lread.c (openp): Don't stuff size_t into an 'int'.
12395 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12396 about possible signed overflow.
12398 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12399 (GDK_KEY_g): Don't define if already defined.
12400 (xg_prepare_tooltip): Avoid pointer signedness problem.
12401 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12403 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12404 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12406 * xfns.c (Fx_window_property): Simplify a bit,
12407 to make a bit faster and to avoid GCC 4.6.0 warning.
12408 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12410 * fns.c (internal_equal): Don't assume size_t fits in int.
12412 * alloc.c (compact_small_strings): Tighten assertion a little.
12414 Replace pEd with more-general pI, and fix some printf arg casts.
12415 * lisp.h (pI): New macro, generalizing old pEd macro to other
12416 conversion specifiers. For example, use "...%"pI"d..." rather
12417 than "...%"pEd"...".
12418 (pEd): Remove. All uses replaced with similar uses of pI.
12419 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12420 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12421 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12422 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12423 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12424 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12425 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12427 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12428 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12429 * print.c (safe_debug_print, print_object): Likewise.
12430 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12432 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12433 avoiding the 0 flag, which is not portable.
12434 * process.c (Fmake_network_process): Use pI to avoid cast.
12435 * region-cache.c (pp_cache): Likewise.
12436 * xdisp.c (decode_mode_spec): Likewise.
12437 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12438 behavior on 64-bit hosts with printf arg.
12439 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12440 (x_stop_queuing_selection_requests): Likewise.
12441 (x_get_window_property): Don't truncate byte count to an 'int'
12444 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12445 here, since it parses constructs like leading '-' and spaces,
12446 which are not wanted; and it overflows with large numbers.
12447 Instead, simply match F[0-9]+, which is what is wanted anyway.
12449 * alloc.c: Remove unportable assumptions about struct layout.
12450 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12451 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12452 (allocate_vectorlike, make_pure_vector): Use the new macros,
12453 plus offsetof, to remove unportable assumptions about struct layout.
12454 These assumptions hold on all porting targets that I know of, but
12455 they are not guaranteed, they're easy to remove, and removing them
12456 makes further changes easier.
12458 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12459 This doesn't fix a bug but makes the code clearer.
12460 (string_overrun_cookie): Now const. Use initializers that
12461 don't formally overflow signed char, to avoid warnings.
12462 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12463 can cause Emacs to crash when string overrun checking is enabled.
12464 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12465 multiple of sizeof (EMACS_INT); it need not be, if
12466 alignof(EMACS_INT) < sizeof (EMACS_INT).
12467 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12469 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12471 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12473 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12475 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12476 supposed to be handshaking. (Bug#8556)
12477 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12479 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12481 * lisp.h (Qdebug): List symbol.
12482 * eval.c (Qdebug): Restore global linkage.
12483 * keyboard.c (debug-on-event): New variable.
12484 (handle_user_signal): Break into debugger when debug-on-event
12485 matches the current signal symbol.
12487 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12489 * alloc.c (check_sblock, check_string_bytes)
12490 (check_string_free_list): Convert to standard C.
12492 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12494 * w32.c (emacs_gnutls_push): Fix typo.
12496 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12498 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12499 "cast to pointer from integer of different size".
12501 Improve doprnt and its use in verror. (Bug#8545)
12502 * doprnt.c (doprnt): Document the set of format control sequences
12503 supported by the function. Use SAFE_ALLOCA instead of always
12506 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12507 is one byte too soon. Don't use xrealloc; instead xfree and
12510 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12512 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12515 * gnutls.c: Renamed global_initialized to
12516 gnutls_global_initialized. Added internals for the
12517 :verify-hostname-error, :verify-error, and :verify-flags
12518 parameters of `gnutls-boot' and documented those parameters in the
12519 docstring. Start callback support.
12520 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12521 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12522 on error. Return error code.
12523 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12524 (emacs_gnutls_read): Likewise.
12525 (Fgnutls_boot): Return handshake error code.
12526 (emacs_gnutls_handle_error): New function.
12527 (wsaerror_to_errno): Likewise.

12564 to changes in oldXMenu/XMenu.h from 2011-04-16.
12565 (struct XMenu): Declare `help_text' `const char **'.

12582 changes in globals.h immediately force recompilation.
12583 (TAGS): Depend on $(CURDIR)/m/intel386.h and
12584 $(CURDIR)/s/ms-w32.h.
12585 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

12589 <char-direction-table>: Deleted.
12591 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12593 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
12594 * doprnt.c: Include limits.h.
12595 (SIZE_MAX): New macro.
12596 (doprnt): Return a size_t value. 2nd arg is now size_t.
12597 Many local variables are now size_t instead of int or unsigned.
12598 Improve overflow protection. Support `l' modifier for integer
12599 conversions. Support %l conversion. Don't assume an EMACS_INT
12600 argument for integer conversions and for %c.
12602 * lisp.h (doprnt): Restore prototype.
12604 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
12605 $(SRC)/character.h.
12607 * Makefile.in (base_obj): Add back doprnt.o.
12609 * deps.mk (doprnt.o): Add back prerequisites.
12610 (callint.o): Depend on character.h.
12612 * eval.c (internal_lisp_condition_case): Include the handler
12613 representation in the error message.
12614 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
12615 when breaking from the loop.
12617 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
12619 * callint.c (Fcall_interactively): When displaying error message
12620 about invalid control letter, pass the character's codepoint, not
12621 a pointer to its multibyte form. Improve display of the character
12622 in octal and display also its hex code.
12624 * character.c (char_string): Use %x to display the (unsigned)
12625 codepoint of an invalid character, to avoid displaying a bogus
12628 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
12629 `error', not SYMBOL_NAME itself.
12631 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
12632 character arguments to `error'.
12634 * charset.c (check_iso_charset_parameter): Fix incorrect argument
12635 to `error' in error message about FINAL_CHAR argument. Make sure
12636 FINAL_CHAR is a character, and use %c when it is passed as
12637 argument to `error'.
12639 2011-04-23 Eli Zaretskii <eliz@gnu.org>

12827 ns_descriptor_to_entity that were caused by using free to
12828 deallocate memory blocks that were allocated by xmalloc (via

12850 * process.c (send_process): Adjust to the new signatures of
12851 emacs_write and emacs_gnutls_write. Do not attempt to store

13183 * buffer.c (buffer_count): Remove unused var.

13187 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
13188 * dispextern.h (bidi_dump_cached_states): Remove, since it's
13189 exported only to the debugger.

13192 * atimer.h (run_all_atimers): Remove; not exported.
13194 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
13195 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
13196 was inaccessible from Lisp.
13197 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
13198 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
13200 alloc.c: Import and export fewer symbols, and remove unused items.
13201 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13203 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13204 it's not optimized away by whole-program optimization.
13205 (message_enable_multibyte, free_misc): Remove.
13206 (catchlist, handlerlist, mark_backtrace):

13217 (mark_backtrace): Define only if BYTE_MARK_STACK.
13218 * xdisp.c (message_enable_multibyte): Now static.
13220 Declare Lisp_Object Q* variables to be 'static' if not exported.
13221 This makes it easier for human readers (and static analyzers)
13222 to see whether these variables are used from other modules.
13223 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

13233 Remove decls of unexported vars.
13234 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13236 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13238 Make Emacs functions such as Fatom 'static' by default.
13239 This makes it easier for human readers (and static analyzers)
13240 to see whether these functions can be called from other modules.
13241 DEFUN now defines a static function. To make the function external
13242 so that it can be used in other C modules, use the new macro DEFUE.

13248 Remove decls, since these functions are now static.
13249 (Funintern, Fget_internal_run_time): New decls, since these functions
13250 were already external.
13252 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

13260 Mark functions with DEFUE instead of DEFUN,
13261 if they are used in other modules.
13262 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13263 decls for now-static functions.
13264 * buffer.h (Fdelete_overlay): Remove decl.
13265 * callproc.c (Fgetenv_internal): Mark as internal.

13274 * image.c (Finit_image_library): New forward static decl.
13275 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13276 * intervals.h (Fprevious_property_change):
13277 (Fremove_list_of_text_properties): Remove decls.
13278 * keyboard.c (Fthis_command_keys): Remove decl.
13279 (Fcommand_execute): New forward static decl.

13295 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13297 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13300 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13302 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13303 when at ZV. (Bug#8487)
13305 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13307 * charset.c (Fclear_charset_maps): Use xfree instead of free.

13313 * xsettings.c (read_and_apply_settings): Likewise.
13315 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13316 (overrun_check_free): Protoize.
13318 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13320 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13321 since callers should never pass a negative size.
13322 Change the signature to match that of plain 'read' and 'write'; see
13323 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13324 * lisp.h: Update prototypes of emacs_write and emacs_read.
13326 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13328 * xdisp.c (redisplay_window): Don't try to determine the character
13329 position of the scroll margin if the window start point w->startp
13330 is outside the buffer's accessible region. (Bug#8468)
13332 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13334 Fix write-region and its subroutines for buffers > 2GB.
13335 * fileio.c (a_write, e_write): Modify declaration of arguments and
13336 local variables to support buffers larger than 2GB.
13337 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13339 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13340 argument, local variables, and return value.
13342 * lisp.h: Update prototypes of emacs_write and emacs_read.
13344 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13346 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13348 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13350 Fix more problems found by GCC 4.6.0's static checks.
13352 * xdisp.c (vmessage): Use a better test for character truncation.
13354 * charset.c (load_charset_map): <, not <=, for optimization,
13355 and to avoid potential problems with integer overflow.
13356 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13357 * casetab.c (set_identity, shuffle): Likewise.
13358 * editfns.c (Fformat): Likewise.
13359 * syntax.c (skip_chars): Likewise.
13361 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13362 This also lets GCC 4.6.0 generate slightly better loop code.
13364 * callint.c (Fcall_interactively): <, not <=, for optimization.
13365 (Fcall_interactively): Count the number of arguments produced,
13366 not the number of arguments given. This is simpler and lets GCC
13367 4.6.0 generate slightly better code.
13369 * ftfont.c: Distingish more carefully between FcChar8 and char.
13370 The previous code passed unsigned char * to a functions like
13371 strlen and xstrcasecmp that expect char *, which does not
13372 conform to the C standard.
13373 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13374 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13375 char * when the C standard requires it.
13377 * keyboard.c (read_char): Remove unused var.
13379 * eval.c: Port to Windows vsnprintf (Bug#8435).
13380 Include <limits.h>.
13381 (SIZE_MAX): Define if the headers do not.
13382 (verror): Do not give up if vsnprintf returns a negative count.
13383 Instead, grow the buffer. This ports to Windows vsnprintf, which
13384 does not conform to C99. Problem reported by Eli Zaretskii.
13385 Also, simplify the allocation scheme, by avoiding the need for
13386 calling realloc, and removing the ALLOCATED variable.
13388 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13390 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13391 But keep the doprint source code for now, as we might revamp it
13392 and use it again (Bug#8435).
13393 * lisp.h (doprnt): Remove.
13394 * Makefile.in (base_obj): Remove doprnt.o.
13395 * deps.mk (doprnt.o): Remove.
13397 error: Print 32- and 64-bit integers portably (Bug#8435).
13398 Without this change, on typical 64-bit hosts error ("...%d...", N)
13399 was used to print both 32- and 64-bit integers N, which relied on
13400 undefined behavior.
13401 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13402 * lisp.h (error, verror): Mark as printf-like functions.
13403 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13404 Report overflow in size calculations when allocating printf buffer.
13405 Do not truncate output string at its first null byte.
13406 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13407 Truncate the output at a character boundary, since vsnprintf does not
13409 * charset.c (check_iso_charset_parameter): Convert internal
13410 character to string before calling 'error', since %c now has the
13412 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13413 overflow when computing char to be passed to 'error'. Do not
13414 pass Lisp_Object to 'error'; pass the integer instead.
13415 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13416 formatted with plain %d.
13418 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13420 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13422 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13424 * xterm.c (x_catch_errors): Remove duplicate declaration.
13426 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13428 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13430 2011-04-10 Jim Meyering <meyering@redhat.com>
13432 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13433 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13434 return ssize_t not "int", and use size_t as the buffer length.
13435 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13436 * gnutls.h: Update declarations.
13437 * process.c (read_process_output): Use ssize_t, to match.
13438 (send_process): Likewise.
13440 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13442 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13444 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13446 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13447 Use unsigned char, to match FcChar8 type definition.
13449 * xterm.c (handle_one_xevent):
13450 * xmenu.c (create_and_show_popup_menu):
13451 * xselect.c (x_decline_selection_request)
13452 (x_reply_selection_request): Avoid type-punned deref of X events.
13454 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13456 Fix some uses of `int' instead of EMACS_INT.
13457 * search.c (string_match_1, fast_string_match)
13458 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13459 (scan_buffer, find_next_newline_no_quit)
13460 (find_before_next_newline, search_command, Freplace_match)
13461 (Fmatch_data): Make some `int' variables be EMACS_INT.
13463 * xdisp.c (display_count_lines): 3rd argument and return value now
13464 EMACS_INT. All callers changed.
13465 (pint2hrstr): Last argument is now EMACS_INT.
13467 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13468 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13469 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

13480 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13481 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13483 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13484 (encode_invocation_designation): Last argument P_NCHARS is now
13486 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13487 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13489 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13492 * ccl.c (Fccl_execute_on_string): Declare some variables
13495 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13497 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13499 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13501 * process.c (Fformat_network_address): Doc fix.
13503 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13505 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13507 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13509 * keyboard.c (read_char): Call Lisp function help-form-show,
13510 instead of using internal_with_output_to_temp_buffer.

13527 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13529 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13531 Fix more problems found by GCC 4.6.0's static checks.
13533 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

13537 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13539 * xdisp.c (vmessage): Mark as a printf-like function.
13541 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

13546 printf-like functions.
13547 (tiff_load): Add casts to remove these marks before passing them
13548 to system-supplied API.
13550 * eval.c (Fsignal): Remove excess argument to 'fatal'.
13552 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
13553 This avoids several warnings with gcc -Wstrict-overflow.
13554 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
13555 directly, rather than having caller test rule sign. This avoids
13556 some unnecessary tests.
13557 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
13558 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
13559 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
13561 * xfont.c (xfont_text_extents): Remove var that was set but not used.
13562 (xfont_open): Avoid unnecessary tests.
13564 * composite.c (composition_gstring_put_cache): Use unsigned integer.
13566 * composite.h, composite.c (composition_gstring_put_cache):
13567 Use EMACS_INT, not int, for length.
13569 * composite.h (COMPOSITION_DECODE_REFS): New macro,
13570 breaking out part of COMPOSITION_DECODE_RULE.
13571 (COMPOSITION_DECODE_RULE): Use it.
13572 * composite.c (get_composition_id): Remove unused local vars,
13573 by using the new macro.
13575 * textprop.c (set_text_properties_1): Change while to do-while,
13576 since the condition is always true at first.
13578 * intervals.c (graft_intervals_into_buffer): Mark var as used.
13579 (interval_deletion_adjustment): Return unsigned value.
13582 * process.c (list_processes_1, create_pty, read_process_output):
13583 (exec_sentinel): Remove vars that were set but not used.
13584 (create_pty): Remove unnecessary "volatile"s.
13585 (Fnetwork_interface_info): Avoid possibility of int overflow.
13586 (read_process_output): Do adaptive read buffering even if carryover.
13587 (read_process_output): Simplify nbytes computation if buffered.

13591 * syntax.c (scan_words): Remove var that was set but not used.
13592 (update_syntax_table): Use unsigned instead of int.
13594 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
13595 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
13596 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13598 * print.c (print_error_message): Avoid int overflow.
13600 * font.c (font_list_entities): Redo for clarity,
13601 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13603 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13604 (font_score): Avoid potential overflow in diff calculation.
13606 * fns.c (substring_both): Remove var that is set but not used.
13607 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13609 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13611 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13612 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13613 can always succeed if overflow has undefined behavior.
13615 * search.c (boyer_moore, wordify): Remove vars set but not used.
13616 (wordify): Omit three unnecessary tests.
13618 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13619 All callers changed. This avoids the need for an unused var.
13621 * casefiddle.c (casify_region): Remove var that is set but not used.
13623 * dired.c (file_name_completion): Remove var that is set but not used.
13625 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13627 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13628 (Finsert_file_contents): Remove unnecessary code checking fd.
13630 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13631 Check for integer overflow on size calculations.
13633 * buffer.c (Fprevious_overlay_change): Remove var that is set
13636 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13637 Remove vars that are set but not used.
13638 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13639 (timer_check_2): Mark vars as initialized.
13641 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13643 * image.c (lookup_image): Remove var that is set but not used.
13644 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13646 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13647 that are set but not used.
13649 * xfns.c (make_invisible_cursor): Don't return garbage
13650 if XCreateBitmapFromData fails (Bug#8410).
13652 * xselect.c (x_get_local_selection, x_handle_property_notify):
13653 Remove vars that are set but not used.
13655 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13656 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13658 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13659 Remove var that is set but not used.
13660 (scroll_bar_windows_size): Now size_t, not int.
13661 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13662 Check for overflow.
13664 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13665 (map_tty_color) [!defined MSDOS]: Likewise.
13667 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13669 * coding.c: Remove vars that are set but not used.
13670 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13671 All callers changed.
13672 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13673 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13674 (decode_coding_charset): Remove vars that are set but not used.
13676 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13677 that is set but not used.
13679 * print.c (print_object): Remove var that is set but not used.
13681 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13682 The gnulib version avoids calling malloc in the usual case,
13683 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13684 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13685 * filelock.c (current_lock_owner): Likewise.
13686 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13687 * sysdep.c: Include allocator.h, careadlinkat.h.
13688 (emacs_no_realloc_allocator): New static constant.
13689 (emacs_readlink): New function.
13690 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13691 ../lib/careadlinkat.h.
13693 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13695 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13696 first non-nil return value).
13698 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13700 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13701 if not defined (Bug#8403).
13703 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13705 * xdisp.c (display_count_lines): Remove parameter `start',
13706 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13707 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13708 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

13710 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13711 and thereabouts. All callers changed.
13712 (get_per_char_metric): Remove parameter `f', unused since
13713 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13715 2011-04-02 Jim Meyering <meyering@redhat.com>
13717 do not dereference NULL upon failed strdup
13718 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13719 (ns_get_family): Likewise.
13721 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13723 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13725 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13727 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13730 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13732 Add lexical binding.
13734 * window.c (Ftemp_output_buffer_show): New fun.
13735 (Fsave_window_excursion):
13736 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13738 * lread.c (lisp_file_lexically_bound_p): New function.
13739 (Fload): Bind Qlexical_binding.
13740 (readevalloop): Remove `evalfun' arg.
13741 Bind Qinternal_interpreter_environment.
13742 (Feval_buffer): Bind Qlexical_binding.
13743 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13745 (syms_of_lread): Declare `lexical-binding'.
13747 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13749 * keyboard.c (eval_dyn): New fun.
13750 (menu_item_eval_property): Use it.
13752 * image.c (parse_image_spec): Use Ffunctionp.
13754 * fns.c (concat, mapcar1): Accept byte-code-functions.
13756 * eval.c (Fsetq): Handle lexical vars.
13757 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13758 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13759 (FletX, Flet): Obey lexical binding.
13760 (Fcommandp): Handle closures.
13761 (Feval): New `lexical' arg.
13762 (eval_sub): New function extracted from Feval. Use it almost
13763 everywhere where Feval was used. Look up vars in lexical env.
13765 (Ffunctionp): Move from subr.el.
13766 (Ffuncall): Handle closures.
13767 (apply_lambda): Remove `eval_flags'.
13768 (funcall_lambda): Handle closures and new byte-code-functions.
13769 (Fspecial_variable_p): New function.
13770 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13771 but without exporting it to Lisp.
13773 * doc.c (Fdocumentation, store_function_docstring):
13774 * data.c (Finteractive_form): Handle closures.
13776 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13779 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13781 (exec_byte_code): New function extracted from Fbyte_code to handle new
13782 calling convention for byte-code-functions. Add new byte-codes.
13784 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13786 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13788 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13790 * xdisp.c (redisplay_internal): Fix prototype.
13792 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13794 * xdisp.c (SCROLL_LIMIT): New macro.
13795 (try_scrolling): Use it when setting scroll_limit.
13796 Limit scrolling to 100 screen lines.
13797 (redisplay_window): Even when falling back on "recentering",
13798 position point in the window according to scroll-conservatively,
13799 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13801 (try_scrolling): When point is above the window, allow searching
13802 as far as scroll_max, or one screenful, to compute vertical
13803 distance from PT to the scroll margin position. This prevents
13804 try_scrolling from unnecessarily failing when
13805 scroll-conservatively is set to a value slightly larger than the
13806 window height. Clean up the case of PT below the margin at bottom
13807 of window: scroll_max can no longer be INT_MAX. When aggressive
13808 scrolling is in use, don't let point enter the opposite scroll
13809 margin as result of the scroll.
13810 (syms_of_xdisp) <scroll-conservatively>: Document the
13811 threshold of 100 lines for never-recentering scrolling.
13813 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13815 * dispextern.h (move_it_by_lines):
13816 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13817 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13818 (message_log_check_duplicate): Remove parameters `prev_bol' and
13819 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13820 (redisplay_internal): Remove parameter `preserve_echo_area',
13821 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13823 * indent.c (Fvertical_motion):
13824 * window.c (window_scroll_pixel_based, Frecenter):
13825 Don't pass `need_y_p' to `move_it_by_lines'.
13827 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13829 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13830 steal a few bits to be more compact.
13831 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13832 Remove unneeded casts.
13834 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13836 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13838 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13839 binding" message (bug#7967).
13841 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13843 Fix more problems found by GCC 4.6.0's static checks.
13845 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13846 Remove unused local var.
13848 * editfns.c (Fmessage_box): Remove unused local var.
13850 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13851 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13852 Omit unused local vars.
13853 * window.c (shrink_windows): Omit unused local var.
13854 * menu.c (digest_single_submenu): Omit unused local var.
13855 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13856 Omit unused local var.
13858 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13859 Don't assume string length fits in int.
13860 (keyremap_step, read_key_sequence): Use size_t for sizes.
13861 (read_key_sequence): Don't check last_real_key_start redundantly.
13863 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13864 instead of alloca (Bug#8344).
13866 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13867 (Fbacktrace_frame): Don't assume nframes fits in int.
13869 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13871 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13874 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13876 * cm.c (calccost): Turn while-do into do-while, for clarity.
13878 * keyboard.c (syms_of_keyboard): Use the same style as later
13879 in this function when indexing through an array. This also
13880 works around GCC bug 48267.
13882 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13884 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13886 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13887 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13889 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13890 This avoids undefined behavior on integer overflow, and is a bit
13891 more convenient anyway since it is compared to a size_t variable.
13893 Variadic C functions now count arguments with size_t, not int.
13894 This avoids an unnecessary limitation on 64-bit machines, which
13895 caused (substring ...) to crash on large vectors (Bug#8344).
13896 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13897 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13905 * fns.c (concat): Likewise.
13906 * frame.c (x_set_frame_parameters): Likewise.
13907 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13908 0 if not found, not -1. All callers changed.
13910 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13911 (stack_copy_size): Now size_t, not int.
13912 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13914 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13916 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13917 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13918 All callers changed.
13920 * lisp.h (multibyte_char_to_unibyte):
13921 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13922 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13926 * keymap.c (push_key_description):
13927 * search.c (Freplace_match):
13928 * xdisp.c (message_dolog, set_message_1): All callers changed.
13930 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13932 * keyboard.c (safe_run_hook_funcall): New function.
13933 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13934 don't set the hook to nil, but remove the offending function instead.
13935 (Qcommand_hook_internal): Remove, unused.
13936 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13937 Vcommand_hook_internal.
13939 * eval.c (enum run_hooks_condition): Remove.
13940 (funcall_nil, funcall_not): New functions.
13941 (run_hook_with_args): Call each function through a `funcall' argument.
13942 Remove `cond' argument, now redundant.
13943 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13944 (Frun_hook_with_args_until_failure): Adjust accordingly.
13945 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

13951 * print.c (strout): Remove parameter `multibyte', unused since
13952 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13954 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13955 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13956 All callers changed.
13958 * w32.c (_wsa_errlist): Use braces for struct initializers.
13960 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13961 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13962 All callers changed.

14117 * buffer.c (Fkill_all_local_variables):
14118 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14120 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14121 unconditionally since it does the check itself.
14123 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14125 Fix more problems found by GCC 4.5.2's static checks.
14127 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14128 the first time through the loop, since we know p0 < p1 then.
14129 This also avoids a gcc -Wstrict-overflow warning.
14131 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14132 leading to a memory leak, possible in functions like
14133 load_charset_map_from_file that can allocate an unbounded number
14134 of objects (Bug#8318).
14136 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14137 that could (at least in theory) be that large.
14139 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14140 This is less likely to overflow, and avoids undefined behavior if
14141 overflow does occur. All callers changed. Use strtoul to scan
14142 for the unsigned long integer.
14143 (pint2hrstr): Simplify and tune code slightly.
14144 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

14159 * process.c (Fmake_network_process): Use socklen_t, not int,
14160 where POSIX says socklen_t is required in portable programs.
14161 This fixes a porting bug on hosts like 64-bit HP-UX, where
14162 socklen_t is wider than int (Bug#8277).
14163 (Fmake_network_process, server_accept_connection):
14164 (wait_reading_process_output, read_process_output):
14167 * process.c: Rename or move locals to avoid shadowing.

14177 Make tparam.h and terminfo.c consistent.
14178 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14179 Include tparam.h instead, since it declares them.
14180 * cm.h (PC): Remove extern decl; tparam.h now does this.
14181 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14182 * terminfo.c: Include tparam.h, to check interfaces.
14183 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14184 (tparam): Adjust signature to match interface in tparam.h;
14185 this removes some undefined behavior. Check that outstring and len
14186 are zero, which they always are with Emacs.
14187 * tparam.h (PC, BC, UP): New extern decls.
14189 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14190 (xftfont_open): Rename locals to avoid shadowing.

14207 (find_automatic_composition, composition_adjust_point): Likewise.
14208 (composition_update_it): Mark var as initialized.
14209 (find_automatic_composition): Mark vars as initialized,
14210 with a FIXME (Bug#8290).

14214 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14215 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14216 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14217 to avoid shadowing.

14229 Fix pointer signedness.
14230 (alsa_choose_format): Remove unused local var.
14231 (wav_play): Initialize a variable to 0, to prevent undefined
14232 behavior (Bug#8278).
14234 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14236 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14238 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14239 clobbering (Bug#8298).
14240 * sysdep.c (sys_subshell): Likewise.
14241 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14243 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14244 This should get cleaned up, so that child_setup has the
14245 same signature on all platforms.
14247 * callproc.c (call_process_cleanup): Now static.
14248 (relocate_fd): Rename locals to avoid shadowing.
14250 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14252 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14253 not to be necessary, and produces flickering.
14255 2011-03-20 Glenn Morris <rgm@gnu.org>
14257 * config.in: Remove file.
14259 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

14304 Define only if needed.
14306 * unexelf.c (unexec): Name an expression,
14307 to avoid gcc -Wbad-function-cast warning.
14308 Use a different way to cause a compilation error if anyone uses
14309 n rather than nn, a way that does not involve shadowing.
14310 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14312 * deps.mk (unexalpha.o): Remove; unused.

14418 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14419 to use the following functions instead of these macros.
14420 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14421 EMACS_INT, since callers assume the returned value fits in int.
14422 (upcase1): Likewise, for UPCASE_TABLE.
14423 (uppercasep, lowercasep, upcase): New static inline functions.
14424 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
14425 the race-condition problem in the old DOWNCASE.
14427 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
14428 Rename locals to avoid shadowing.
14429 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14430 (regex_compile, re_search_2, re_match_2_internal):
14431 Remove unused local vars.
14432 (FREE_VAR): Rewrite so as not to use empty "else",
14433 which gcc can warn about.
14434 (regex_compile, re_match_2_internal): Mark locals as initialized.
14435 (RETALLOC_IF): Define only if needed.
14436 (WORDCHAR_P): Likewise. This one is never needed, but is used
14437 only in a comment talking about a compiler bug, so put inside
14438 the #if 0 of that comment.
14439 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14440 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14443 * search.c (boyer_moore): Rename locals to avoid shadowing.
14444 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
14445 (PREV_CHAR_BOUNDARY): Likewise.
14447 * search.c (simple_search): Remove unused var.
14449 * dired.c (compile_pattern): Move decl from here ...

14453 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
14455 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
14457 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
14458 Rename locals to avoid shadowing.
14459 (Fvertical_motion): Mark locals as initialized.

14462 (casify_region): Mark local as initialized.
14464 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
14466 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14467 New macros, so that the caller can use some names other than
14468 gcpro1, gcpro2, etc.
14469 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14471 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14472 argument, for consistency with GCPRO2_VAR, etc: it is now the
14473 prefix of the variable, not the variable itself. All uses
14475 * dired.c (directory_files_internal, file_name_completion):
14476 Rename locals to avoid shadowing.
14478 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14479 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14480 dired.c's scmp function, had undefined behavior.
14481 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14482 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14483 * buffer.h: ... to here, because these macros use current_buffer,
14484 and the new implementation with inline functions needs to have
14485 current_buffer in scope now, rather than later when the macros
14487 (downcase, upcase1): New static inline functions.
14488 (DOWNCASE, UPCASE1): Reimplement using these functions.
14489 This avoids undefined behavior in expressions like
14490 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14491 from race conditions in accessing the global variables
14492 case_temp1 and case_temp2.
14493 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14494 * lisp.h (case_temp1, case_temp2): Remove their decls.
14495 * character.h (ASCII_CHAR_P): Move from here ...
14496 * lisp.h: ... to here, so that the inline functions mentioned
14497 above can use them.
14499 * dired.c (directory_files_internal_unwind): Now static.
14501 * fileio.c (file_name_as_directory, directory_file_name):
14502 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
14504 (file_name_as_directory): Use const pointers when appropriate.
14505 (Fexpand_file_name): Likewise. In particular, newdir might
14506 point at constant storage, so make it a const pointer.
14507 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
14508 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
14510 (Fset_file_times, Finsert_file_contents, auto_save_error):

14514 (Ftry_completion, Fall_completions): Rename or remove locals
14515 to avoid shadowing.
14517 * marker.c (bytepos_to_charpos): Remove; unused.
14519 * lisp.h (verify_bytepos, count_markers): New decls,
14520 so that gcc does not warn that these functions aren't declared.
14522 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
14523 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
14524 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
14525 (copy_text): Remove unused local var.
14527 * filelock.c (within_one_second): Now static.
14528 (lock_file_1): Rename local to avoid shadowing.
14530 * buffer.c (fix_overlays_before): Mark locals as initialized.
14531 (fix_start_end_in_overlays): Likewise. This function should be
14532 simplified by using pointers-to-pointers, but that's a different
14534 (switch_to_buffer_1): Now static.
14535 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
14536 (report_overlay_modification): Rename locals to avoid shadowing.
14538 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
14539 Fix pointer signedness issue.
14540 (sys_subshell): Mark local as volatile if checking for lint,
14541 to suppress a gcc -Wclobbered warning that does not seem to be right.
14542 (MAXPATHLEN): Define only if needed.
14544 * process.c (serial_open, serial_configure): Move decls from here ...
14545 * systty.h: ... to here, so that they can be checked.
14547 * fns.c (get_random, seed_random): Move extern decls from here ...
14548 * lisp.h: ... to here, so that they can be checked.
14550 * sysdep.c (reset_io): Now static.
14551 (wait_for_termination_signal): Remove; unused.
14553 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
14554 (copy_keymap_item, append_key, push_text_char_description):
14556 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
14557 (DENSE_TABLE_SIZE): Remove; unused.
14558 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
14559 (describe_map_tree):
14560 Rename locals to avoid shadowing.
14562 * keyboard.c: Declare functions static if they are not used elsewhere.
